Lil Find: Maternity Tights That Ride High, Not Low

babysugar — Sat, 13 Sep 2008 05:00:52 -0700

Tights can be downright uncomfortable even when you aren't pregnant, but a growing belly only exacerbates the slip and slide tight action around your middle. I've found Italian low rise tights are more comfy than regular hosiery, but plenty of designers make maternity tights.

I like these full length Mama Spanx ($28) because they have a pregnancy panel with underbelly support and can be pulled up above your belly instead of sitting under it like most maternity pants.

Fetal-maternal erythrocyte distribution

admin — Thu, 04 Sep 2008 19:09:54 -0700

HEALTH GUIDE REFERENCE FROM A.D.A.M

Definition

The fetal-maternal erythrocyte distribution test is used to measure the number of fetal red blood cells in a pregnant woman's blood. (See also Rh incompatibility.)

Alternative Names

Kleihauer-Betke stain

How the test is performed

Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic. An elastic band is placed around the upper arm to apply pressure and cause the vein to swell with blood.

A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the band is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.

The sample is taken to the laboratory where the hemoglobin is removed and both fetal and maternal red blood cells are counted. Based on that count a ratio of fetal to maternal blood cells is determined.

How to prepare for the test

No special preparation is necessary for this test.

How the test will feel

When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.

Why the test is performed

Rh incompatibility occurs when the mother's blood type is Rh-negative (Rh-) and her unborn baby's blood type is Rh-positive (Rh+). If the mother is Rh+, or if both parents are Rh-, there is no reason to worry about Rh incompatibility.

If the baby's blood is Rh+ and gets into the mother's Rh- blood stream, her body will produce antibodies. These antibodies could pass back through the placenta and harm the developing baby's red blood cells, causing mild to serious anemia in the fetus.

This test determines the amount of blood that has been exchanged between the mother and fetus. All Rh- pregnant women should receive this test when bleeding or risk of bleeding events occur during a pregnancy.

In a woman whose blood is ABO incompatible with her infant, this test helps determine the amount of Rh immune globulin (RhoGAM) an Rh-negative woman must receive to prevent her from developing abnormal proteins that attack the fetus in future pregnancies.

Normal Values

A normal value indicates that no or few fetal cells are present in the maternal blood. The standard dose of RhoGAM is sufficient in this case.

What abnormal results mean

A high fetal-maternal red blood cell ratio means there blood from the fetus is leaking into the mother's blood circulation. The greater the amount of fetal cells present, the greater the amount of Rh immune globulin the mother must receive.

What the risks are

The risks associated with drawing blood are slight, but include:

Excessive bleeding
Fainting or feeling light-headed
Hematoma (blood accumulating under the skin)
Infection (a slight risk any time the skin is broken)
Multiple punctures to locate veins

Global Prevalence of Tension-Type Headache

Tension-type headaches account for nearly half of all headaches, according to a 2007 study in Cephalagia. The researchers estimated that more people are disabled by tension-type headache than by migraine.

Causes of Tension-Type Headaches

Doctors are not really sure why tension-type headaches occur. Possible causes include muscle contractions or changes in brain chemicals. Several studies in 2006 and 2007 presented the theory that tension-type headaches may be due to myofascial trigger points in the shoulders and neck, as well as poor head posture. Some researchers suggest that tension-type headaches may be related to fibromyalgia, a condition that is also characterized by myofascial pain.

Tension-type headaches may be triggered by:

Chronic poor posture
Overwork and stress
Lack of sleep
Dental problems, including temporomandibular joint disorder (TMJ)
Certain types of foods
Skipping meals
Medication overuse
Hormonal changes related to menstruation

Managing Tension-Type Headaches

Acetaminophen (Tylenol) or non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen (Motrin, Advil), naproxen (Aleve), or ketoprofen (Actron, Orudis KT) can usually provide pain relief for tension-type headache attacks. Patients who have chronic headaches sometimes take amitriptyline (Elavil), a prescription tricyclic antidepressant, to help prevent attacks. Exercise, stress reduction, and relaxation techniques are very important lifestyle approaches for controlling tension-type headaches.

Introduction

Most people are familiar with headaches, the all too common affliction marked by throbbing, piercing, or vise-like pain around much or a part of the head. There are many different kinds of headaches, and they range from being an infrequent annoyance to a persistent, severe, and disabling medical condition.

The brain itself is insensitive to pain, so that is not what hurts when a headache arises. The pain, instead, occurs in the following locations:

The tissues covering the brain
The attaching structures at the base of the brain
Muscles and blood vessels around the scalp, face, and neck

Doctors categorize headaches as either primary or secondary, which helps to distinguish the many different kinds of headaches and to determine appropriate treatments for each.

Primary Headaches. A headache is considered primary when a disease or other medical condition does not cause it. Most primary headaches fall into three main types: Tension-type, migraine, and cluster headaches.

Tension headache is the most common primary headache and accounts for 90% of all headaches.
Neurovascular headaches are the second most frequently occurring primary headaches and include migraines (the more common) and cluster headaches. Such headaches are caused by an interaction between blood vessel and nerve abnormalities. [See In-Depth Report #97: Migraine headaches and In-DepthReport #99: Cluster headaches.]

Headaches are usually caused by muscle tension, vascular problems, or both. Migraines are vascular in origin, and may be preceded by visual disturbances, loss of peripheral vision, and fatigue. Over-the-counter pain medications can relieve most headaches.

Symptoms of migraine and tension-type headaches often overlap, and a diagnosis is sometimes difficult.

Secondary Headaches. Secondary headaches are caused by other medical conditions, such as sinus infections, neck injuries, and strokes. About 2% of headaches are secondary to abnormalities or infections in the nasal or sinus passages, and they are commonly referred to as sinus headaches.

Chronic Daily Headaches. The International Headache Society's classification system includes a category called chronic daily headaches. They may originate as tension headaches, migraines, or a combination of these or other headache types. Chronic daily headaches affect 4 - 5% of the population.

Click the icon to see an image of the different types of headache.

Chronic daily headaches are defined as any benign headache that occurs at least 15 days a month and is not associated with a serious neurologic abnormality. Most people with these headaches have them daily, or almost daily, and they can be quite debilitating.

Chronic daily headaches are, in turn, subdivided into two categories:

Short-duration headaches last fewer than 4 hours. The most common short-acting chronic headaches are cluster headaches.
Long-duration headaches last more than 4 hours. Tension-type headaches are the most common type of long-duration chronic (recurring) headaches and, in fact, the most common type of chronic headaches in general.

General Description. Tension-type headaches, also called muscle contraction headaches or simply tension headaches, are the most common of all headaches. Tension-type headaches can last minutes to days and have the following characteristics:

The pain is commonly described as a tight feeling, as if the head were in a vise. It usually occurs on both sides of the head and is often experienced in the forehead, in the back of the head and neck, or in both regions. Soreness in the shoulders or neck is common.
Depression, anxiety, and sleeping problems may accompany persistent headaches.
Sufferers of tension-type headaches may also have migraine-like symptoms, including being sensitive to light or noise (but not both). Some patients also may suffer from visual disturbances. (Such symptoms in tension headaches, however, tend to be less severe than in migraine. Tension headaches also do not cause nausea or limit activities to the degree that migraines do.)

Types of Tension Headache. In 2004, the International Headache Society updated its original 1988 classification criteria. Tension-type headaches are now divided into the following four classifications:

Frequent episodic tension-type headache. Headaches occur at least once but not more than 15 days per month for at least 3 months (a minimum of 12 days but not more than 180 days per year). Headaches last from at least 30 minutes to 7 days.
Infrequent episodic tension-type headache. At least 10 episodes of headache that occur less than 1 day per month (12 days per year). Because these headaches occur infrequently, they do not impact a patient's quality of life as severely as frequent episodic headaches and may not require attention from a medical professional.
Chronic tension-type headache. Headaches occur at least 15 days per month for at least 3 months (180 days per year). The headache persists for hours at a time and may be continuous.
Probable tension-type headache. Probable tension headaches may be classified as probable frequent episodic, probable infrequent episodic, or probable chronic. They have most, but not all, of the symptoms of tension-type headaches and are not attributed to migraine without aura or other neurological disorders. Probable chronic tension-type headache may be related to medication overuse.

Migraine Headache: General Description of Its Course. Migraine is now recognized as a chronic illness, not simply as a headache. These headaches are often classified by whether or not auras accompany them:

Common migraines are without auras. About 75% of migraines are the common type.
Classic migraines are those with auras.

A person may experience one or the other at different times.

In general, there are four symptom phases to a migraine (although they may not all occur in every patient): the prodrome phase, auras, the attack, and the postdrome phase.

Prodrome. The prodrome phase is a group of vague symptoms that may precede a migraine attack by several hours, or even a day or two. Prodrome symptoms include:

Sensitivity to light or sound
Changes in appetite
Fatigue and yawning
Malaise
Mood changes
Food cravings

Auras. Auras are sensory disturbances that occur before the migraine attack in between 20 - 25% of patients. Visually, auras are referred to as being positive or negative:

Positive auras include bright or shimmering light or shapes at the edge of their field of vision called scintillating scotoma. They can enlarge and fill the line of vision. Other positive aura experiences are zigzag lines or stars.
Negative auras are dark holes, blind spots, or tunnel vision (inability to see to the side).
Patients may have mixed positive and negative auras. This is a visual experience that is sometimes described as a fortress with sharp angles around a dark center.

Other neurologic symptoms may occur at the same time as the aura, although they are less common. They include:

Speech disturbances
Tingling, numbness, or weakness in an arm or leg
Perceptual disturbances such as space or size distortions
Confusion

Migraine Attack. If untreated, attacks usually last from four to 72 hours. A typical migraine attack produces the following symptoms:

Throbbing pain on one side of the head. The word migraine, in fact, is derived from the Greek word hemikrania, meaning "half of the head" because the pain of migraine often occurs on one side. Pain also sometimes spreads to affect the entire head.
Pain worsened by physical activity.
Nausea, sometimes with vomiting.
Visual symptoms.
Facial tingling or numbness.
Extreme sensitivity to light and noise.
Looking pale and feeling cold.
Less common symptoms include tearing and redness in one eye, swelling of the eyelid, and nasal congestion, including runny nose. (Such symptoms are more common in certain other headaches, notably cluster headaches. In one study, however, they occurred in over 40% of migraine sufferers.)

Postdrome. After a migraine attack, there is usually a postdrome phase, in which patients may feel exhausted and mentally foggy for a while.

Cluster Headache. Cluster headaches are very painful events. Patients typically awaken a few hours after they go to sleep with the following symptoms:

Very severe, stabbing pain centered in one eye.
Excessive tearing, a drooping eyelid, and one stuffy or runny nostril, all on the same side as the pain.
Feelings of intense restlessness are common. People in the throes of a cluster headache may pace the floor or may even bang their heads against the wall in an attempt to cope with the pain.
Cluster headaches often have a cycle with the following pattern:
Attacks themselves are usually brief, lasting 30 - 90 minutes, although they can persist for up to 3 hours.
During an active period, sufferers can experience as few as one attack every other day to one or more daily. In a rare form of cluster headache, known as chronic paroxysmal hemicrania, as many as six attacks per day can occur.
An active period of recurrent cluster attacks typically extends over 4 - 12 weeks.
Headache-free periods last several months to even years.

Hemicrania Continua. Hemicrania continua is a rare form of chronic headache. Such headaches occur on one side of the face, mostly in women. The patient generally experiences continuous low-level headache with periodic attacks that can last days to weeks. (About 10% of patients experience remissions.) The actual attacks can be mild to severe, and may resemble migraines. The headaches can usually be treated successfully with NSAIDs such as indomethacin (Indocin). Migraine medications are typically not as helpful.

Prognosis

Both episodic tension-type headache and chronic daily headache affect quality of life. Tension-type headache episodes are rarely disabling, however, and rarely require emergency treatment. If they do, usually there is a migraine component occurring with the tension-type headache.

Nevertheless, although they are not medically dangerous, chronic tension headaches have a negative impact on quality of life, families, and work productivity. Several studies have reported lower quality of life with any chronic daily headache compared to those with no headaches or who have only episodic ones. In one study, people with tension-type headaches tended to have higher anxiety and lower quality of life during a headache attack than people with migraines (who, however, were less able to cope during a migraine attack).

In one study, two-thirds of patients with chronic tension-type headaches reported daily or near daily headaches for an average of 7 years. Only 12% reported headaches occurring less than 20 days a month. In the study, 74% of the patients had to take some time off from work because of the headaches, and about a third reported impaired sleep, less energy, and reduced emotional well-being on 10 or more days a month. Most were able to carry out their daily responsibilities even when in pain, although at lower than normal capacity. This and other studies report a strong association between anxiety and depression and chronic tension-type headaches.

Causes

There does not appear to be a single cause of chronic tension-type headache. Many factors are likely involved.

One of the most popular theories on the cause of tension-type headaches involves muscle contraction in the head, neck, and shoulders. There are several ideas about how muscle tension may produce these headaches.

The most common cause of tension-type headaches is muscle contraction in the head, neck or shoulders.

Studies have suggested that tension-type headache sufferers may have higher-than-average muscle tenderness in the face and head that make them more susceptible to headache after muscle contractions. A few studies suggest that some patients with chronic headaches may be overly sensitive to pain in general or may overestimate muscle contraction pain.

One theory suggests that sustained tension or stress that produces muscle contractions in the tender areas around the skull constrict blood vessels. Blood flow is reduced so oxygen is blocked and waste matter builds up, resulting in pain.

Still, pain can last long after the muscles have relaxed, and clear evidence is lacking on how or even if muscle contractions are a major cause of tension headache.

Researchers are increasingly finding evidence to support factors that are common to both migraine and tension-type headache. Some research suggests that both problems may result from a continuum of abnormalities in the central nervous system (the nerves in the brain and spine). Such changes trigger a progression of symptoms starting with mild sensations, developing into tension headache, and finally, progressing in some people to a migraine.

Serotonin and Other Neurotransmitter Levels. Neurotransmitters are chemical messengers in the brain. Serotonin is a neurotransmitter (chemical messenger in the brain) that is important for sleep, well-being, and other factors that affect quality of life. Abnormalities in serotonin levels have been observed in both tension-type and migraine headache sufferers. Altered levels of other neurotransmitters, importantly dopamine and stress hormones, also occur with migraine and tension-type headaches.

Dopamine, for example, may act as a stimulant of the migraine process. Some evidence suggests that certain genetic factors make people oversensitive to the effects of dopamine, which include nerve cell excitation. Such nerve-cell over-activity could trigger the events in the brain leading to migraine. The prodromal symptoms (mood changes, yawning, drowsiness), for example, have been associated with increased dopamine activity. Dopamine receptors are also involved in regulation of blood flow in the brain.

Reduced Magnesium Levels. Magnesium deficiencies have been observed in people with both tension-type and migraine headaches. Researchers have noted a drop in magnesium levels before or during a migraine attack. Magnesium plays a role in nerve cell function. Reduced levels could be a destabilizing factor, causing the nerves in the brain to misfire, possibly even accounting for the auras that many sufferers experience.

Nitric Oxide. Other research suggests that over-excitable neurons release nitric oxide, a small molecular messenger, which may be important in triggering in most primary headaches (tension-type, cluster, and migraines). Elevated levels have been observed in blood cells of patients with tension-type headache. Some evidence suggests that the release of this molecule in blood vessels may activate nerve pathways in the brain, muscles, or elsewhere and increase pain.

Estrogen Fluctuations in Women. Tension-type headaches and migraine headaches are more common in females during adolescence and adulthood. Most likely hormone fluctuations, rather than whether levels are elevated or low, trigger headaches. Some research suggests that fluctuations in estrogen levels may impact levels of serotonin and other pain-modulating substances that affect these headaches.

Inflammation in the Maxillary Nerve. Early studies suggest that some chronic tension-type and migraine headaches may be caused by inflammation in the nerve that runs behind the cheekbone (the maxillary nerve) -- not around the covering of the brain. In fact, some work using ice water for reducing swelling in areas of the gums above the last upper molars has relieved some severe migraine and tension-type headaches.

Genetic factors appear to play a role in predisposing people to recurrent tension headaches. One study of twins suggested that the chances of inheriting the susceptibility to recurring headaches (both migraine and tension) were about 70% in close relatives. The trait is equal in both boys and girls. Because such headaches tend to occur more in females, however, hormonal, social, psychological, or other factors must play a role in their development.

Tension-type headache has been highly associated with an intense response to stress. Some studies suggest that patients with chronic tension-type headaches have more general feelings of anxiety or depression and are less able to express their emotions. One study indicated that patients with tension headaches tend to perceive everyday events as more stressful than those without headaches. Some research even suggests that tension-type headache victims may have some biological predisposition for translating stress into muscle contraction. Still, the link between stress and tension-type headaches is not fully understood, and some evidence challenges any causal association.

Whiplash, concussions, and other head and neck injuries, even mild ones, may result in persistent tension-type or migraine headaches in both adults and children. Such headaches should be treated as if they were the primary types. The risk for tension headaches may persist for years after the injury.

Myofascial pain involves the fascia (connective tissue) and muscles. Some researchers think that tension-type headaches may be linked to myofascial trigger points in the neck and shoulder muscles. Trigger points are knots in the muscle tissue that can cause tightness, weakness, and intense pain in various areas of the body. (For example, a trigger point in the shoulder may result in headache.) Because fibromyalgia is also characterized by myofascial pain, researchers are exploring whether there may be an association between this condition and tension-type headache. [See In-Depth Report #76: Fibromyalgia.]

Medication Overuse (Rebound) Headache. About a third of persistent headaches -- whether chronic migraine or tension-type -- are medication-overuse headaches. These are the result of a rebound effect caused by the regular overuse of headache medications. Nearly any headache medication can produce this effect. In one study of headache sufferers, medication-overuse headaches developed after an average of 1.7 years of regular use of triptans (18 doses a month), after 2.7 years of ergot use (37 doses as month), and after 4.8 years using painkillers (114 doses a month). Regular use of painkillers for any chronic problem (such as arthritis) poses a 2% risk for medication-overuse headache, with risk being highest in people who already have primary headaches, especially migraines.

Chronic Migraines. In some cases, migraines naturally evolve into chronic, daily headaches referred to as transformed migraines.

About 90% of people seeking help for headaches have a primary headache. The rest are secondary headaches, caused by an underlying disorder that produces headache as a symptom. More than 300 conditions can cause headaches. Some of the most common are listed below.

Sinus Headaches. Many primary headaches, including migraines, are misdiagnosed as sinus headaches. Sinus headaches can occur in the front of the face, usually around the eyes, across the cheeks, or over the forehead. They are usually mild in the morning and increase during the day and are usually accompanied by fever, runny nose, congestion, and general debilitation. Sinus headaches spread over a larger area of the head than migraines, but it is often difficult to tell them apart, particularly if headache is the only symptom of sinusitis. They even coexist in many cases. Often, the visual changes associated with migraine can rule out sinusitis, but such visual changes do not occur with all migraines. (In rare cases, sinusitis can cause double vision and even vision loss, a sign of very serious infection.)

Headaches that Originate in the Neck. Some headaches may be caused by abnormalities of the neck muscles (called cervicogenic headaches). Nerves in the neck converge in the trigeminal nerve, which is the largest nerve in the skull. It originates in the brain stem and supplies sensation to the face. This nerve can generate pain signals to the facial area that the brain may interpret as headache. Pain is usually on one side. Even if it affects both sides of the head it is usually more severe on one side. The quality of the headache may be difficult to distinguish from an aching tension headache or a mild migraine without aura. Cervicogenic headaches can result from prolonged poor posture (such as that caused by sitting in front of a computer keyboard or driving daily for long periods), arthritis, injuries of the upper spine, or abnormalities in the cervical spine (the spinal bones in the neck).

Temporomandibular Joint Disorder. Muscle contractions that cause headaches may be a result of temporomandibular joint dysfunction (TMJ, also known as TMD), which is caused by clenching the jaws or grinding the teeth (usually during sleep), or by abnormalities in the jaw joints themselves. The diagnosis is easy if chewing produces pain or if jaw motion is restricted or noisy. TMJ pain can occur in the ear, cheek, temples, neck, or shoulders. This condition often coexists with chronic tension headache.

Click the icon to see an image of temporomandibular joint dysfunction.

Glaucoma. Acute glaucoma is caused by increased pressure in the eye and requires immediate medical attention. Throbbing pain may be felt around or behind the eyes or in the forehead. Patients have redness in the eye and may see halos or rings around lights.

Brain Tumor. Fear of brain tumor is common among people with headaches, but headache is almost never the first or only sign of a tumor. Changes in personality and mental functioning, vomiting, seizures, and other symptoms are more likely to appear first. When the headache does develop, it is often worse early in the morning or may awaken sufferers during the night.

Neuralgia. Neuralgia is pain due to nerve abnormalities, which can occur in the facial area and resemble migraines or sinus headaches.

Hypertension. Although many people attribute headaches to high blood pressure, evidence suggests that hypertension does not cause headaches. An exception is malignant hypertension, an uncommon medical emergency in which the blood pressure abruptly rises to extreme levels, causing damage to blood vessels in the brain, heart, and kidneys.

Strokes Caused by Blood Clots or Hemorrhages. A blood clot or hemorrhage in the brain leading to a stroke can cause a severe headache, sometimes referred to as a thunderclap headache when it is very sudden and severe. The onset of such a headache, particularly if it is associated with confusion, stupor, or other neurologic symptoms, mandates prompt medical attention.

Epilepsy. Severe headaches that can last 12 hours or longer are very common in epilepsy. Migraine is particularly associated with epilepsy.

Head Injuries. It is obvious that a significant blow to the head will cause pain. In most cases, the pain is similar to tension-type headache and is treated in the same way as the primary headache. Post-injury headaches, however, can reflect serious damage, ranging from skull fractures to internal bleeding, and monitoring is important.

Disorders of the Meninges. The meninges are the membranes covering the brain and the spinal cord. Meningitis, which is an infection or irritation of these membranes, is an uncommon but potentially serious cause of severe headache. Other symptoms include nausea and stiffness or pain in the neck.

Gynecologic Problems. Many clinicians have anecdotally linked gynecologic problems, such as ovarian cysts and menstrual disorders, to chronic headaches, and new data are emerging to support this association.

Temporal (Giant Cell) Arteritis. Certain causes of headaches are unique to the elderly, such as temporal arteritis, also called giant cell arteritis. Inflammation in arteries that carry blood to the head, neck, and sometimes the upper part of the body can cause very severe headaches. The risk for this headache is highest in people over age 70, especially among women, people of European heritage, and patients with polymyalgia rheumatica.

Miscellaneous Causes of Benign Headaches. Rapid consumption of ice cream or other very cold foods or beverages is the most common trigger of sudden headache pain, which may be prevented by warming the food or drink for a few seconds in the front of the mouth before swallowing. Other common benign causes of headache include eyestrain, dental problems, allergies, systemic infections, and caffeine withdrawal. Headaches may be induced by sexual activity or intense physical exertion. Leakage from spinal cord fluid is rare but can cause headaches that may be mistaken for brain tumors.

Risk Factors

Tension-type headaches are the most common headaches, accounting for nearly half of all headaches. According to one study, nearly 40% of Americans have at least one episode of tension headache during the course of a year. Some reports estimate that over 85% of women and about 63% of men will have a tension-type headache at some point during a year. Nearly everyone has at least one tension-type headache during their lifetime.

Surveys indicate that about 3 - 5% of the general population has chronic tension-type headache, with the prevalence being higher in women.

About 40% of people with tension-type headaches first have them before they are age 20, and another 40% first experience them between ages 20 - 40. Most of the remaining headache sufferers first have tension-type headaches in the decade between ages 40 - 50. Chronic tension-type headache tends to occur in older adults.

Headaches in Children. Headaches are rare before age 4 but increase in prevalence throughout childhood, reaching a peak around age 13. In one large study, about 7% of seven year olds and 15% of 11 year olds had headaches. Ten percent of these childhood headaches were recurrent. In many of these patients, chronic headaches persist into adulthood. In addition, as adults these patients have a tendency to develop multiple physical or psychiatric complaints, such as back pain, muscle aches, digestive complaints, and depression.

Studies have found that only a minority of chronic childhood headaches are due to physical conditions, such as head injuries or medical problems. In one study, over 62% of children with tension-type headache episodes suffered some form of emotional disorder. In the study, every child reported the presence of a stress factor.

Psychological factors associated with childhood tension-type headaches include:

Sleep problems. According to one study, more than two-thirds of children who experience chronic daily headaches suffer from sleep disturbances, especially difficulty falling asleep.
Moderate or severe depression.
Emotional rigidity in a child and more repressed anger than their peers.
Family stress. This includes maternal illness or separation, family bereavement, relationship problems, mental illness in a family member, and other stressful family events.
Problems at school. According to a National Headache Foundation survey, nearly 30% of children miss school because of headaches. For many children, the start of the school season can be a particularly stressful time.

The National Headache Foundation recommends these tips for parents:

Keep a diary of child’s headaches noting time of onset, length and intensity of attack, location of pain, and food triggers.
Make sure child gets plenty of sleep at regular times.
Avoid changes in child’s eating routing (hunger and eating at irregular times can trigger headaches).
Discuss any headache concerns with child’s doctor.

The following conditions can make people susceptible to tension-type headaches.

Chronic poor posture
Chronic overwork
Upper respiratory tract infections, such as colds and flu
Sleep disorders. Sleep problems, such as insomnia, sleep apnea, or habitual snoring, are common in all primary headaches. Headache can disturb sleep, but sleep disorders may also contribute directly to tension headache, particularly those that occur at night or early morning. (In one study, treating people who had chronic headaches for sleep apnea cured the headaches in many cases.)
Obesity
Hypothyroidism (decreased thyroid function)
Dental problems
Allergies
Substance or alcohol abuse
Temporomandibular joint dysfunction (TMJ, also called TMD). This is a condition in which there are abnormalities in the jaw joints. TMJ itself can cause headache, and it also often coexists with chronic tension headache.

Certain triggers, including the following, may cause headache episodes in people with chronic tension-type headaches:

Specific stressful events
Not eating on time
Fatigue or lack of sleep
Crying. In one study, only stress, anxiety, and menstruation were more important headache triggers in women.
Withdrawal from over-used substances (caffeine, nicotine, alcohol, pain relievers)
Eyestrain
Intense physical exertion, including sexual activity. Athletes are at higher risk for headaches. Patients with tension-type headaches should not avoid exercise, however. Ordinary levels of physical activity do not usually precipitate these headaches. Furthermore, a sedentary lifestyle may increase the risks for stress and obesity and thereby for tension headaches in susceptible people.
Certain foods, such as chocolate, cheese, and the flavor enhancer monosodium glutamate (MSG), are commonly cited as triggers for tension headaches as they are for migraines.
Medications (overuse of headache medications, nitrates, certain anti-depressants, some drugs used to treat high blood pressure, and many others.)
Hormonal changes, such as specific menstrual phases, in women.

Weather conditions, certain smells, smoke, and light, which can set off migraines, are not common triggers for tension-type headaches.

The rapid consumption of ice cream or other very cold foods or beverages is a well-known trigger of sudden headache pain -- the so-called "ice cream" headache. It can be easily prevented by warming the food or drink for a few seconds in the front of the mouth before swallowing. Drinking a glass of room-temperature water quickly relieves the pain.

Diagnosis

Diagnosing the cause of persistent daily headache is difficult, even for expert doctors. Studies report that people who visit the emergency room with disabling headache are often misdiagnosed as tension-type headaches instead of migraines. It is important to choose a doctor who is sensitive to the needs of headache sufferers and aware of the latest advances in treatment.

Extensive testing may be advised for anyone with a chronic, daily headache. Tracking times of medications, withdrawal, and headache, using the headache diary, is usually very helpful in diagnosis.

According to the International Headache Society, a diagnosis of tension-type headache is suggested by the following symptoms:

Pressing or tightening (but non-pulsating) feeling
Mild-to-moderate pain on both sides of the head
Not aggravated by routine physical activity (walking, etc.)

In episodic tension-type headaches:

No nausea or vomiting
Photophobia (intolerance of light) or phonophobia (intolerance of sound) may be absent or one of these symptoms (but not both) may be present

In chronic tension-type headaches:

No vomiting
No moderate or severe nausea
No more than one of the following symptoms: Mild nausea, photophobia, or phonophobia
Some types of chronic tension headache may include tenderness upon manual palpitation of the head (pericranial tenderness).

Differentiating Medication-Overuse (Rebound) Headache from Tension-Type Headache. About a third of persistent headaches are the result of the rebound effect caused by the overuse of headache medications (formerly called rebound headaches).

Usually in such cases, medications have been taken on an ongoing basis for more than 3 days each week. If patients stop taking these drugs, the headaches come back. The patient then starts taking the drugs again. Eventually the headache simply persists and medications are no longer effective. Even after successful medication withdrawal, relapse is common, particularly with drugs that contain caffeine, so doctors should check for this type of headache even in patients who have previously been treated.

Medications implicated in medication-overuse headache include barbiturates, sedatives, narcotics, and migraine medications, particularly those that also contain caffeine. (Heavy caffeine use can also cause this condition.) Simple painkillers, such as aspirin or ibuprofen, are less likely causes of medication-overuse headaches.

Differentiating Tension Headaches from Chronic Migraines. It is often difficult to differentiate between chronic migraine and chronic tension-type headaches. The McGill Pain Questionnaire may be useful for ruling out migraine. According to a 2003 study, patients with migraine who answer the questionnaire report significantly more severe specific symptoms (throbbing, stabbing, gnawing, hot, sickening, exhausting) than those with tension-type headaches. There is very little difference between these headaches, however, in scores of overall severity of the pain.

For an accurate diagnosis, the patient should describe the following:

Duration and frequency of headaches
Recent changes in their character
Location of the pain
Type of pain (throbbing or steady pressure)
Intensity of the headache
Associated symptoms, such as visual disturbances or nausea and vomiting. (These are seen most often with migraines.)
Behaviors during a headache. Different behaviors may help distinguish between migraine and tension headaches. People with tension headaches tend to relieve pain by massaging the scalp, temples, or the nape of the neck. People with migraines are more likely to compress the forehead and temples (tying a scarf around the head) or to apply cold to the area. They also tend to isolate themselves, lie down, induce vomiting, and use more pillows than usual. (None of these maneuvers do much good in relieving either headache, unfortunately.)

The patient should try to recall what seems to bring on the headache and anything that relieves it. Keeping a headache diary is a useful way to identify triggers that bring on headaches. Be sure to include all events preceding an attack. Often two or more triggers interact to produce a headache.

Researchers are investigating triggers of headaches to determine if certain ones are more likely to set off different primary headaches. In general, however, the same stimuli seem to trigger any of the primary headaches, although people with migraines may be more sensitive to some of them (weather, certain smells, light, and smoke) than people with tension headaches.

Tracking medications is an important way of identifying medication-overuse headache or transformed migraine.

Be sure to attempt to define the intensity of the headache. There are different scoring symptoms available that help communicate the severity of the pain to the doctor. For instance, the following is a number system that can be helpful:

1 = Mild, barely noticeable

2 = Noticeable, but does not interfere with work/activities

3 = Distracts from work/activities

4 = Makes work/activities very difficult

5 = Incapacitating

The patient should report any other conditions that might be associated with headache, including but not limited to the following:

Any chronic or recent illness and their treatments
Any injuries, particularly head or back injuries
An uncharacteristic dietary changes
Any current medications or recent withdrawal from any drugs, including over-the-counter or natural remedies
Any history of caffeine, alcohol, or drug abuse
Any serious stress, depression, and anxiety
The doctor will also need the patient's general medical and family history, particularly concerning headaches or other diseases such as epilepsy. Migraine, in particular, tends to run in families.

In order to diagnose a chronic headache, the doctor will examine the head and neck and will usually perform a neurologic examination, which includes a series of simple exercises to test strength, reflexes, coordination, and sensation. The doctor will also examine the eyes to rule out pressure build-up in the eye as a cause of headache. The doctor may ask questions to test short-term memory and related aspects of mental function.

Imaging tests of the brain may be recommended under the following circumstances:

If the results of the history and physical examination suggest neurologic problems.
For patients with headache that wakes them at night.
For new headaches in the elderly. In this age group, it is particularly important to first rule out age-related disorders, including stroke, hypoglycemia, hydrocephalus, and head injuries (usually from falls).
For patients with worsening headache.

They are not recommended for patients with migraine and with no other abnormal indications.

The following tests may be used:

A CT (computed tomography) scan may be ordered to rule out other conditions, particularly chronic sinusitis, which, in one study, occurred in 20% of patients with chronic headache. Other findings include aneurysms, benign or cancerous growths, and other abnormalities in the brain.
X-rays and other tests may also be used if sinusitis is strongly suspected.
A neck x-ray can reveal arthritis or spinal problems.
Other tests include an MRI (magnetic resonance imaging), EEG (electroencephalogram), lumbar puncture, ultrasound testing, and cerebral angiography, which are only performed if there is reason to suspect an underlying disease.

Headaches indicating a serious underlying problem, such as cerebrovascular disorder or malignant hypertension, are uncommon. (It should again be emphasized that a headache is not a common symptom of a brain tumor.) People with existing chronic headaches, however, might miss a more serious condition believing it to be one of their usual headaches. Such patients should immediately call a doctor if the quality of a headache or accompanying symptoms has changed. Everyone should call a doctor for any of the following symptoms:

Sudden, severe headache that persists or increases in intensity over the following hours, sometimes accompanied by nausea, vomiting, or altered mental states (possible hemorrhagic stroke).
Sudden, very severe headache, worse than any headache ever experienced (possible indication of hemorrhage or a ruptured aneurysm).
Chronic or severe headaches that begin after age 50.
Headaches in the back of the head accompanied by other symptoms, such as memory loss, confusion, loss of balance, changes in speech or vision, or loss of strength in or numbness or tingling in arms or legs (possibility of small stroke in the base of the skull).
Headaches after head injury, especially if drowsiness or nausea are present (possibility of hemorrhage).
Headaches accompanied by fever, stiff neck, nausea, and vomiting (possibility of spinal meningitis).
Headaches that increase with coughing or straining (possibility of brain swelling).
A throbbing pain around or behind the eyes or in the forehead accompanied by redness in the eye and perceptions of halos or rings around lights (possibility of acute glaucoma).
A one-sided headache in the temple in elderly people; the artery in the temple is firm and knotty and has no pulse; scalp is tender (possibility of temporal arteritis, which can cause blindness or even stroke if not treated).
Sudden onset and then persistent, throbbing pain around the eye possibly spreading to the ear or neck unrelieved by pain medication (possibility of blood clot in one of the sinus veins of the brain).

Managing Tension-Type Headaches

Given the very high prevalence of tension-type headaches, some experts express frustration over the lack of serious scientific attention given to this problem. Unfortunately, few tension headache sufferers seek medical help for their problem, and 60% of those with severe headaches use only over-the-counter medications. Many patients fear that they will not be taken seriously by their doctor or believe the widespread misperceptions that their problem is due solely to stress. With medications, relaxation training, lifestyle changes, and other therapies, over 90% of patients can be helped.

Fortunately, most acute tension-type headaches get better without any treatment, and simple over-the-counter pain relievers such as acetaminophen or non-steroidal anti-inflammatory drugs (NSAIDs) can treat mild symptoms.

The most common pain relievers are:

Acetaminophen (Tylenol, Anacin-3, Panadal, Phenaphen, Valadol)
Over-the-counter NSAIDs include aspirin, ibuprofen (Motrin IB, Advil, Nuprin, Rufen), naproxen (Aleve), ketoprofen (Actron, Orudis KT)
Prescription NSAIDs include ibuprofen (Motrin), naproxen (Naprosyn, Anaprox), diclofenac (Voltaren), tolmetin (Tolectin), ketoprofen (Orudis, Oruvail)

Acetaminophen may be effective for moderate-to-severe headaches only at high doses (1,000 mg), while NSAIDs can be effective at lower doses. One study indicated that ibuprofen and naproxen were more effective than aspirin or acetaminophen.

There are few proven therapies for treating or preventing chronic tension-type headaches, and studies are weak. To date, the major treatments used for chronic tension-type headache are a group of antidepressants called tricyclics, and cognitive-behavior therapy. Used alone either of these approaches achieves modest benefits, at best. A combination, however, may be very helpful in some cases.

Some research suggests the following steps in treating this condition:

Because many chronic daily headaches are due to over-use of headache medications, withdrawal from such drugs is the first action. (NSAIDs or other painkillers should not be used to prevent chronic tension-type headaches.)
Cognitive behavioral therapies, including relaxation and stress-reduction techniques, should be used next for managing headaches. They should be the first option for children and adolescents with chronic headaches.
If medication withdrawal and psychological methods fail to bring improvement, tricyclic antidepressants are tried next in combination with cognitive therapy.
Physical therapy, massage therapy, or acupuncture may help some people.

If headaches develop because of medication overuse, the patients cannot recover without stopping the drugs. (If caffeine is the culprit, a person may only need to reduce coffee or tea drinking to a reasonable level, not necessarily stop drinking it altogether.) The patient usually has the option of stopping abruptly or gradually and should expect the following course:

Most headache drugs can be stopped abruptly, but the patient should be sure to check with the doctor before withdrawal. Certain non-headache medications, such as anti-anxiety drugs or beta-blockers, require gradual withdrawal.
If the patient chooses to taper off standard headache medications, withdrawal should be completed within three days or shorter. Otherwise the patient may become discouraged.
No matter which approach is used for stopping medication, the patient must expect a period of worsening headache for a few days afterward. Alternative pain relievers may be administered during the first days to help withdrawal.
Most people feel better within 2 weeks, although headache symptoms can persist up to 16 weeks (and in rare cases even longer).

Studies suggest that nearly half of patients with medication-overuse headaches relapse. According to one study, the relapse rate may be much higher for tension headaches (73%) than for migraine headaches (22%). More research is needed to determine the optimal methods for drug withdrawal. On the encouraging side, some patients experience dramatic long-term relief from all headaches afterward.

Medications

The standard treatments for tension-type headaches are non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen, and tricyclic antidepressants, usually amitriptyline (Elavil, Endep).

Several pain relievers are helpful for mild-to-moderate headaches. They should not be used to prevent headaches, however.

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs). NSAIDs are common pain relievers that block prostaglandins, substances that dilate blood vessels and cause inflammation and pain. NSAIDs are usually the first drugs tried for almost any kind of headache. There are dozens of NSAIDs. Aspirin is the most common, but it is not as effective for acute tension-type headache as other NSAIDs. Common NSAIDs include:

Over-the-counter NSAIDs. Aspirin, ibuprofen (Motrin), naproxen (Aleve), ketoprofen (Actron, Orudis KT)
Prescription NSAIDs. Diclofenac (Voltaren, Cataflam, Solaraze), tolmetin (Tolectin), indomethacin (Indocin)

Patients should be aware that long-term use of high-dose NSAIDs may increase the risk for stomach bleeding and heart problems, including heart attack and stroke.

Acetaminophen. Acetaminophen (Tylenol) is a good alternative to NSAIDs when stomach distress, ulcers, or allergic reactions prohibit their use. A high dose (1,000 mg), however, is needed for this drug to be effective for headaches. Midrin (a combination of a drug that narrows blood vessels, a mild sedative, and acetaminophen) may be very helpful for tension-type headaches.

Acetaminophen does have some adverse effects, however, and the daily dose should not exceed 4 grams (4,000 mg). Patients who take high doses of this drug for long periods are at risk for liver damage, particularly if they drink alcohol and do not eat regularly. Acetaminophen may cause serious kidney problems in people who already have kidney disease. It also may interact with certain medications, including the blood thinner warfarin.

Antidepressants known as tricyclics are most often used for prevention of severe chronic tension-type headaches. Newer selective serotonin-reuptake inhibitors (SSRIs) antidepressants are also sometimes used in milder cases.

Tricyclic Antidepressants. Tricyclics are not only useful for depression but also appear to help relieve muscle pain and improve sleep. They are sometimes classified in one of two categories: tertiary or secondary amines:

Tertiary amines include amitriptyline (Elavil) and imipramine (Tofranil). Amitriptyline is the tricyclic most commonly used for tension-type headache. These drugs tend to cause more drowsiness than secondary amines, which may be helpful for patients with sleep problems.)
Secondary amines include desipramine (Norpramin) and nortriptyline (Pamelor, Aventyl). Secondary amines may have fewer side effects than tertiary amines, but they are just as toxic in high amounts.

Less commonly used tricyclics include doxepin (Sinequan), amoxapine (Asendin), maprotiline (Ludiomill), protriptyline (Vivactil), trimipramine (Surmontil), mianserin (Bolvidon), and dothiepin (Prothiaden).

Unfortunately, these drugs can lose effectiveness over time. Side effects are also fairly common with these medications. Drowsiness is the most common, but may vary by specific drug. In addition, side effects most often reported include dry mouth, constipation, blurred vision, sexual dysfunction, weight gain, trouble urinating, heart rhythm problems, and dizziness. Blood pressure may also drop suddenly when sitting up or standing.

Tricyclics can have serious, although rare, side effects, including heart rhythm problems, which can be dangerous for some patients with certain heart diseases. These drugs can be fatal with overdose.

Selective Serotonin-Reuptake Inhibitors. Selective serotonin-reuptake inhibitors (SSRIs) work by increasing levels of serotonin in the brain. SSRIs include fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), fluvoxamine (Luvox), and citalopram (Celexa). Because they act on serotonin specifically, they have fewer side effects than the older antidepressants, such as monoamine oxidase inhibitors (MAOIs), which affect a number of chemicals in the body. SSRIs take 2 - 4 weeks to be effective in most adults and sometimes longer, up to 12 weeks, so their value for treating headaches is limited.

Side effects may include nausea, stomach problems, agitation, insomnia, mild tremor, impulsivity, temporary weight gain or loss, and sexual dysfunction. Death from overdose is extremely rare. Serious interactions can occur with other antidepressants, such as tricyclics and MAOIs.

Designer Antidepressants. Several drugs target other neurotransmitters, such as norepinephrine, alone or in addition to serotonin, and are showing promise for prevention of tension-type headache. The following are some examples:

In one study, bupropion (Wellbutrin) was as effective as a tricyclic in preventing tension-type headaches.
Nefazodone (Serzone), a fast-acting designer antidepressant, was particularly beneficial in a study of patients with chronic daily headaches. After 3 months of treatment, symptoms were reduced by half in over 70% of patients. Nearly 60% of them said their symptoms improved over 75%.
Venlafaxine (Effexor), a designer antidepressant that targets both serotonin and the brain chemical norepinephrine, is showing promise for preventing chronic tension-type headaches (as well as migraines). In one study, patients who took the extended-release form of the drug for 6 months went from an average of 24 tension headaches a month to 15.
Mirtazapine (Remeron) is a unique antidepressant known as a 5-HT2 blocker. It may indirectly enhance the affects of both serotonin and norepinephrine. In one study, it was as effective in treating chronic tension-type headache as the tricyclic Elavil. Mirtazapine has significantly fewer side effects than tricyclics, although it may slightly raise cholesterol and triglyceride levels. It may also cause blurred vision and slight weight gain.

Mild anti-anxiety drugs are occasionally used as an adjunct in treating chronic headaches to decrease muscle contraction or to calm anxiety symptoms during periods of extreme stress. They include alprazolam (Xanax) and clonazepam (Klonopin). They tend to be highly addictive, however, and patients should therefore use them only on a short-term basis.

Tramadol. Tramadol (Ultram) is a pain reliever that has been used as an alternative to opioids. It has opioid-like properties but is not as addictive. (Dependence and abuse have been reported, however.) It can cause nausea, but does not cause severe gastrointestinal problems, as NSAIDs can. Some patients experience severe itching. A combination of tramadol and acetaminophen (Ultracet) is now available and provides more rapid pain relief than tramadol alone and more durable relief than acetaminophen alone. Side effects are the same as for each of these drugs.

Opioids. Opioids, such as codeine or hydrocodone, are sometimes prescribed for severe headaches, although their use is controversial because of the risk for addiction. Methadone is showing promise for patients who do not respond to standard treatments. These drugs are narcotics, however, and may be subject to abuse. Patients must be monitored and reevaluated regularly. Overuse of these drugs can reduce their effectiveness and lead to medication-overuse headaches, so it is important for a doctor to supervise this type of medication. Long-term, high-dosage use of some of these drugs can also lead to kidney disease and ulcers. Other, less serious side effects include gastrointestinal upset, dizziness, and ringing in the ears (tinnitus).

Sedatives. Barbiturates, particularly butalbital (Butalan) and its combinations (Fioricet, Axocet), are occasionally prescribed if other medications fail to provide relief. These drugs are sedatives that also contain pain relievers. Because they pose a very high risk for alcohol-like intoxication, dependence and drug-induced headaches during withdrawal, they should be used very sparingly. Some experts believe they should not be used at all for headaches.

Valproate. In some studies, the anticonvulsant medication valproate has been effective for stopping headaches in some patients with persistent migraines and tension-type chronic daily headaches. In one study, 75% of patients with either type of headache experienced at least a 50% reduction in headache frequency and severity. Minor side effects occurred in a third of the patients. Other anti-seizure medications are under investigation.

Botulinum Toxin. Botulinum toxin A (Botox) injections are now widely used to relax muscles and reduce skin wrinkles. They are also being investigated for chronic daily headaches, which include tension-type headache. This potentially deadly toxin is very safe when tiny amounts are injected into small muscles. In a 2003 study of various headache types (including tension-type headache), over 85% of all the patients had fewer headaches per month and the intensity of the pain. Several 2005 studies reported that Botox injections every 3 months might help patients with chronic daily headaches have fewer headaches. However, other studies have reported no benefit. Botox is not approved for headache treatment.

It should be noted that Botox also causes headaches in about 1% of cases. In some cases, the headaches can be very severe and long lasting (from 8 days to a month). Some researchers suggest that either a contaminated batch of Botox or a specific injection technique may be the cause, but additional investigation is needed.

Tizanidine. Tizanidine (Zanaflex) is a muscle relaxant that is emerging as a possible effective preventive drug in chronic tension-type headaches. Called an alpha2-adrenergic agonist, it blocks the release and effectiveness of a stress chemical in the body called norepinephrine and may also help prevent muscle spasms. Studies have reported that nearly 70% of patients with chronic tension-type headaches experienced a reduction in headache symptoms of 50% or more. It also appears to help patients experiencing medication-overuse headache to withdraw from medications. Side effects are usually minor and include fatigue and dry mouth, although patients taking the drug need to be monitored periodically for potential liver damage.

Nitric Oxide Synthase Inhibitors. Nitric oxide synthase inhibitors block nitric oxide, which may play a role in increasing nerve activity that leads to headache. Drugs being investigated include L-NG methyl arginine hydrochloride (L-NMMA) and L-NG-nitro-arginine. Studies suggest they may be very helpful in reducing chronic tension-type pain.

Treatment

In cases where abnormalities or injuries in the cervical spine (the spinal bones in the neck) cause headaches, a cervical epidural nerve block may be beneficial in treating and preventing further pain. This procedure involves injecting small amounts of a corticosteroid and anesthetic into spaces between the vertebrae in the neck to block the nerves. Some patients have reported significant pain relief from this procedure.

Dental Adjustment. Some reports suggest that dental adjustment to help teeth bite down evenly might help some people with temporomandibular joint disorder and chronic headaches. The results indicated that dental adjustments may be helpful. A systematic review in 2003, however, reported no headache relief from this approach.

Nociceptive Trigeminal Inhibition. A dental device called the NTI (nociceptive trigeminal inhibition) tension suppression system has been approved for relief of headaches due to jaw clenching during the night. The small plastic mouthpiece is fitted by a dentist and slips over the two front teeth, preventing teeth clenching at night. Preliminary studies report some benefits for relief of migraines and associated tension-type headaches.

Techniques using acupuncture points on the body have become popular for managing pain. Studies do show some benefits.

Standard Acupuncture. A major 2001 analysis of 26 trials of acupuncture suggested that it may have some benefit for tension headache, but the evidence to date is not completely convincing. Some studies comparing short-term acupuncture to sham (dummy) procedures report no benefits. A 2005 study suggested that acupuncture may help tension-type headache, but needling at non-acupuncture points worked just as well. This suggests a placebo effect may account for the headache relief experienced by acupuncture patients.

Acupuncture, hypnosis and biofeedback are all alternative ways to control pain. Acupuncture involves the insertion of tiny sterile needles, slightly thicker than a human hair, at specific points on the body.

Percutaneous Electrical Nerve Stimulation. A technique called percutaneous electrical nerve stimulation (PENS) uses low-level electrical pulses delivered through acupuncture needles into soft tissue. Patients are barely aware of the sensation. Some studies are showing some benefits, but strong evidence is still lacking to confirm or refute its benefits.

Acupressure. One acupressure practitioner reports that pressing for 60 seconds on the web space between the forefinger and thumb of the dominant hand erases headache in patients with migraine and tension-type headaches. The specific spot pressed should be the most tender point in the web area. The patient should then lie down for about 15 minutes.

Two investigational procedures called automated or electrical twitch obtaining intramuscular stimulation (ATOIMS or ETOIMS) are showing promise. ATOIMS uses an automated mechanical device that vibrates the muscle using a tiny pin. (The sensation is described as similar to a mosquito bite.) ETOIMS uses an extremely mild electrical current. They can also be used together. Both approaches cause the muscles to twitch and relax, and then the process is stopped. Discomfort is minimal. Small studies are reporting some help in relieving a number of conditions that cause chronic pain, including tension headache.

Spinal manipulation by chiropractors or osteopaths may have some benefits for preventing tension-type headaches. Evidence is stronger on benefits of spinal manipulation for patients with headaches originating from nerve or muscular problems in the neck. Some researchers believe that tension-type headaches relieved by spinal manipulation are probably really caused by neck problems.

In a small 2006 study, daily relaxation exercises combined with three sessions of osteopathic treatment helped reduce the frequency -- but not the intensity -- of tension-type headaches. Another 2006 study suggested that physical therapy that incorporates a craniocervical (head and neck) training program may help reduce tension-type headache frequency, intensity, and duration as well as reduce the need for pain medication. In the 6-week program, patients performed 10-minute exercises twice a day. The exercises were designed to retrain muscles in the head, neck, and shoulders. The benefits of these exercises lasted up to 6 months after the program had ended.

Lifestyle Changes

Good health habits -- including adequate sleep, healthy diet, regular exercise, and good stress management -- are important, along with the following specific measures for headache management. Quitting smoking is essential in reducing the risks for all headaches.

An ancient and potentially effective remedy for tension headaches uses pressure applied to the head (such as a headband or a towel wrapped around the head) plus either heat or cold. In one study, 87% of headache sufferers experienced significant relief, and the rest reported moderate relief while they were wearing special headbands that could be tightened. They applied packs that were frozen or heated in a microwave. (Either heat or cold packs were useful, although people with tension headaches generally preferred cold packs.)

A healthy diet rich in fresh fruits and vegetables and whole grains and low in saturated fats (animal fats) is important to everyone. Fish (particularly oily fish, such as salmon and tuna) and soy are protein sources that may be a good alternative to red meats.

Caffeine. In some people with headaches, caffeine appears to be an excellent companion to medications. One study found that the caffeine equivalent of two and a half of cups of coffee can help treat a tension-type headache by itself. Many medications contain combinations of pain or anxiety relievers and caffeine, which boosts pain-relieving potency and counters drowsiness. Taking ibuprofen along with caffeine is even more effective than either substance alone. (It should be noted that in some people with migraines, the tannin found in coffee or tea may be a trigger for the headache. In addition, withdrawal from caffeine is a major cause of headache.)

Headaches that occur during the night and early morning may be related to sleep disorders. One study reported that treating an underlying sleep disorder, such as sleep apnea or insomnia, in patients who also had headaches resulted in headache cure or improvement in all patients except those who suffered from restless legs syndrome.

Several stress-reduction methods are available that may help counteract the tendency for muscle contraction and uneven blood flow associated with some headaches. Such approaches may be especially helpful for children and pregnant women with chronic headaches. (For information on acupuncture and spinal manipulation, see the Treatment section of this report.)

Among the stress reduction techniques that may be helpful are:

Guided imagery. (This uses body awareness and visualization of pleasant or positive images.)
Biofeedback. This technique works when patients develop awareness of their physical responses and learn to feed this information back to the brain for the purpose of replicating that response. It is often used to reduce muscle tension. One interesting and sometimes effective technique for headaches is called thermal biofeedback. It is based on the concept that hand-warming reduces blood flow to the brain and so relieves headache. The patient learns techniques (such as using specific images) that can raise the temperatures of the hand during a headache. Studies suggest the approach has been helpful in children with tension and migraine headaches.
Autogenic training. This approach combines elements of meditation, relaxation, and self-hypnosis. In one study, it reduced headache frequency and use of medications in patients with tension-type and migraine headaches. It was more successful for tension-type headache.
Massage therapy. In one study, massage therapy of the neck and shoulder muscles reduced the frequency of chronic daily tension-type headaches within the first week of treatment. (It did not have any effect on the intensity of headaches, however.)
Reflexology, an alternative massage method that manipulates the feet, was associated with improvement in 81% of patients with tension or migraine headaches. Patients reported an improvement in energy, well-being, and increased ability to understand the cause of the headaches. In the study, 19% went off medication.
Muscle relaxation exercises.
Self-hypnosis.
Breathing exercises. Studies have reported that correct and rhythmic breathing from the diaphragm can sometimes relieve tension-type headaches. Such breathing exercises may be particularly beneficial when performed with physical movements. (Yoga, in fact, is a practice that combines both and has been helpful in people with headaches.)

Any of these therapies may be used in conjunction with drug therapy.

Numerous herbal remedies are promoted for tension-type headache. It is important that anyone taking herbal or so-called natural remedies be aware of the lack of regulations governing their quality and effectiveness.

Essential Oils. Some patients find relief using two drops of peppermint, eucalyptus, or lavender oil added to one cup of water. The patient soaks a cloth in the solution and applies it as a compress to the head.

Herbs. Generally, manufacturers of herbal remedies and dietary supplements do not need approval from the Food and Drug Administration (FDA) to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been several reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

The following are special concerns for people taking natural remedies for headache:

Feverfew is the most studied herbal remedy for headaches. It does appear to help some people. However, like all effective headache remedies, long-term use can cause a rebound effect. Some experts recommend purchasing feverfew in dried leaf form. Feverfew is generally safe, but side effects can be distressing, particularly canker sores in the mouth (5 - 15% of cases) and stomach distress. Pregnant women or women hoping to become pregnant should not take this herb. People with any blood-clotting disorders should not take it.
Valerian has sedative qualities and is listed on the FDA's list of generally safe products. However, its effects can be dangerously increased if it is used with pharmaceutical sedatives. High doses of valerian can cause blurred vision, excitability, vivid dreams, and changes in heart rhythm.
Comfrey is an herbal remedy used to treat several inflammatory problems. Evidence suggests that comfrey is toxic to the liver. Animal studies have reported a possible cancer risk. It is banned in several countries.

Highlights

Some people are pre-programmed for a heightened response to stress by conditions in the womb. Pregnant women under stress who eat a diet high in protein and low in carbohydrates have babies with higher cortisol levels. Later on, these levels increase in response to stress.
The impact of stress on the heart and circulation system is becoming more clear. Stress causes the body to release inflammatory markers that may worsen heart and circulatory diseases as well as inflammatory disease, such as rheumatoid arthritis. High levels of inflammatory markers are associated with increased risk of heart attack and stroke. Extreme stress can also produce a condition that mimics a heart attack, but is reversible. People under severe stress can experience irregular heart beats that make them susceptible to sudden cardiac death.
Stress also increases the risk of developing type 2 diabetes in women.
Traumatic stress has long been known to cause amnesia, emotional numbness, nightmares, and memory problems. Now it is known that traumatic emotional stress can cause permanent changes in the brain that interfere with the normal way information is accepted, coded, and retrieved.
The good news is that our physical response to stress is increasingly understood. Knowing what occurs at the cellular level may help researchers find more ways to counteract the detrimental physical and emotional effects of stress.

Introduction

Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, the immune system, the lungs, the digestive system, the sensory organs, and brain) gear up to meet the perceived danger.

These stresses could prove beneficial in a critical, life-or-death situation. Over time, however, repeated stressful situations put a strain on the body that may contribute to physical and psychological problems. Chronic (long-term) stress can have real health consequences and should be addressed like any other health concern.

Fortunately, research is showing that lifestyle changes and stress-reduction techniques can help people learn to manage their stress.

People can experience stress from external or internal factors.

External stressors include adverse physical conditions (such as pain or hot or cold temperatures) or stressful psychological environments (such as poor working conditions or abusive relationships). Humans, like animals, can also experience external stressors.
Internal stressors can also be physical (infections, inflammation) or psychological (such as intense worry about a harmful event that may or may not occur). As far as anyone can tell, internal psychological stressors are rare or absent in most animals except humans.

Stressors can also be defined as short-term (acute) or long-term (chronic).

Acute Stress. Acute stress is the reaction to an immediate threat, commonly known as the fight or flight response. The threat can be any situation that is perceived, even subconsciously or falsely, as a danger.

Common acute stressors include:

Noise (which can trigger a stress response even during sleep)
Crowding
Isolation
Hunger
Danger
Infection
High technology effects (playing video games, frequently ringing mobile phones)
Imagining a threat or remembering a dangerous event

Under most circumstances, once the acute threat has passed, levels of stress hormones return to normal. This is called the relaxation response.

Chronic Stress. Frequently, modern life poses ongoing stressful situations that are not short-lived. The urge to act (to fight or flee) must therefore be controlled. Stress, then, becomes chronic.

Common chronic stressors include:

On-going highly pressured work
Long-term relationship problems
Loneliness
Persistent financial worries

The Body's Response

The best way to envision the effect of acute stress is to imagine yourself in a primitive situation, such as being chased by a bear.

In response to seeing the bear, a part of the brain called the hypothalamic-pituitary-adrenal (HPA) system is activated.

Release of Steroid Hormones and the Stress Hormone Cortisol. The HPA systems trigger the production and release of steroid hormones (glucocorticoids), including the primary stress hormone cortisol. Cortisol is very important in organizing systems throughout the body (including the heart, lungs, circulation, metabolism, immune systems, and skin) to deal quickly with the bear.

Release of Catecholamines. The HPA system also releases certain neurotransmitters (chemical messengers) called catecholamines, particularly those known as dopamine, norepinephrine, and epinephrine (also called adrenaline).

Catecholamines activate an area inside the brain called the amygdala, which appears to trigger an emotional response to a stressful event. In the case of the bear, this emotion is most likely fear.

Release of Neuropeptide S. The brain releases neuropeptide S, a small protein that modulates stress by decreasing sleep and increasing alertness and a sense of anxiety. This gives the person a sense of urgency to run away from the bear.

Effects on Long- and Short-Term Memory. During the stressful event, catecholamines also suppress activity in areas at the front of the brain concerned with short-term memory, concentration, inhibition, and rational thought. This sequence of mental events allows a person to react quickly, either to fight the bear or to flee from it. It also interferes with the ability to handle difficult social or intellectual tasks and behaviors during that time.

On the other hand, neurotransmitters at the same time signal the hippocampus (a nearby area in the brain) to store the emotionally loaded experience in long-term memory. In primitive times, this brain action would have been essential for survival, since long-lasting memories of dangerous stimuli (such as the large bear) would be critical for avoiding such threats in the future.

The stress response also affects the heart, lungs, and circulation:

As the bear comes closer, the heart rate and blood pressure increase instantaneously.
Breathing becomes rapid, and the lungs take in more oxygen.
The spleen discharges red and white blood cells, allowing the blood to transport more oxygen throughout the body. Blood flow may actually increase 300 - 400%, priming the muscles, lungs, and brain for added demands.

The effect on the immune system from confrontation with the bear is similar to organizing a defensive line of soldiers to potentially critical areas. The steroid hormones reduce the activity in parts of the immune system, so that specific infection fighters (including important white blood cells) or other immune molecules can be repositioned. These immune-boosting troops are sent to the body's front lines where injury or infection is most likely to occur, such as the skin and the lymph nodes.

As the bear gets closer, fluids are diverted from nonessential locations, including the mouth. This causes dryness and difficulty in talking. In addition, stress can cause spasms of the throat muscles, making it difficult to swallow.

The stress effect moves blood flow away from the skin to support the heart and muscle tissues. This also reduces blood loss in the event that the bear causes a wound. The physical effect is a cool, clammy, sweaty skin. The scalp also tightens so that the hair seems to stand up.

Stress shuts down digestive activity, a nonessential body function during short-term periods of hard physical work or crisis.

Once the threat has passed and the effect has not been harmful (for example, the bear has not wounded the human), the stress hormones return to normal. This is known as the relaxation response. In turn, the body's systems also return to normal.

Complications

In prehistoric times, the physical changes in response to stress were an essential adaptation for meeting natural threats. Even in the modern world, the stress response can be an asset for raising levels of performance during critical events, such as a sports activity, an important meeting, or in situations of actual danger or crisis.

If stress becomes persistent and low-level, however, all parts of the body's stress apparatus (the brain, heart, lungs, vessels, and muscles) become chronically over- or under-activated. Such chronic stress may produce physical or psychological damage over time. Acute stress can also be harmful in certain situations, particularly in individuals with preexisting heart conditions.

Studies suggest that the inability to adapt to stress is associated with the onset of depression or anxiety. In one study, two-thirds of subjects who experienced a stressful situation had nearly 6 times the risk of developing depression within that month.

Some evidence suggests that repeated release of stress hormones produces hyperactivity in the hypothalamic-pituitary-adrenal (HPA) system, and disrupts normal levels of serotonin, the nerve chemical that is critical for feelings of well-being. Some people appear to be more at risk for an overactive HPA system under stress, including those with the personality traits that cause perfectionism. Certainly, on a more obvious level, stress reduces the quality of life by reducing feelings of pleasure and accomplishment. In addition, relationships are often threatened in times of stress.

The full impact of mental stress on heart disease is just coming to light, but the underlying mechanisms are not always clear. Stress can certainly influence the activity of the heart when it activates the automatic part of the nervous system that affects many organs, including the heart. Such actions and others could theoretically affect the heart badly in several ways:

Sudden stress increases the pumping action and rate of the heart, while at the same time causing the arteries to constrict (narrow). This restricts blood flow to the heart. A 2002 study suggested that such actions may be responsible for some cases of acute stress that have been associated with a higher risk for serious heart problems. These problems include heart rhythm abnormalities and heart attacks, and even death in people with heart disease.
Emotional effects of stress alter the heart rhythms, which could pose a risk for serious arrhythmias (rhythm abnormalities) in people with existing heart rhythm disturbances.
Stress causes blood to become stickier (possibly in preparation of potential injury), increasing the likelihood of an artery-clogging blood clot.
Stress appears to impair the clearance of fat molecules in the body, raising blood-cholesterol levels, at least temporarily.
Stress that leads to depression appears to be associated with increased intima-medial thickness, a measure of the arteries that signifies worsening blood vessel disease.
Chronic stress may lead to the production of immune factors called cytokines, although study results vary widely. Cytokines produce an inflammatory response that is now believed to be responsible for damaging the arteries. Such damage contributes to heart disease. New studies indicate that some people under stress may have increased levels of C-reactive protein (CRP), a risk marker for heart attack. Each 1 mg/L increase in CRP has been linked to a 20% increased risk of myocaridal ischemia, a condition that signals poor blood flow to the heart muscle.
Stress causes the body to release inflammatory markers into the bloodstream. These markers may worsen heart disease or increase the risk of heart attack or stroke.
Studies have reported an association between stress and high blood pressure, which may be more pronounced in men than in women. According to some evidence, people who regularly experience sudden spikes in blood pressure (caused by mental stress) may, over time, develop injuries in the inner lining of their blood vessels. In one 20-year study, for example, men who periodically measured highest on the stress scale were twice as likely to have high blood pressure as those with normal stress.

Evidence is still needed to confirm any clear-cut relationship between stress and heart disease. For example, a 2002 study in Scotland found no greater risk for actual heart disease or heart events even in men who reported higher mental stress. In fact, higher stress was associated with fewer heart events. Men with high stress levels did tend to complain of chest pain and to go to the hospital for it more often than those with lower stress. They also went to the hospital more often.

Evidence links stress to heart disease in men, particularly in work situations where they lack control. The association between stress and heart problems in women is weaker, and there is some evidence that the ways women cope with stress may be more heart-protective. In one study, men were more apt than women to use alcohol or eat less healthily in response to stress, which might account for their higher heart risks from stress. Different stressors may affect genders differently. In one study, work stress was associated with a higher risk for heart disease in men, but marital stress -- not work stress -- was associated with more severe heart disease in women with existing heart problems.

A condition called stress cardiomyopathy (or Takotsubo cardiomyopathy) is widely recognized. In this disease, intense emotional or physical stress causes severe but reversible heart dysfunction. The patient experiences chest pain, and EKGs and echocardiograms indicate a heart attack, but further tests show no underlying obstructive coronary artery disease.

Acute emotional stress can create abnormal heartbeats. MRI studies show that asymmetric brain activity may play a role in making a stressed heart susceptible to ventricular arrhythmias by creating electrical instability. In some patients, this can cause sudden cardiac death.

Psychological stress is also recognized as a possible cause of acute coronary syndrome (ACS), a collection of symptoms that signify heart attack or approaching heart attack. In one study of men who suffered ACS at work or up to 2 hours after work, many of the men were found to have anger and negative emotions. A 2007 review of studies on blood qualities, coagulation, fibrinolysis, and platelet reactivity found that high levels of psychological stress are associated with harmful changes to the blood. The research suggests that stress has the potential to trigger ACS, particularly in patients with heart disease. The studies also suggest that the risk is greatest immediately after the stressful incident, rather than during it.

Stress Reduction and Heart Disease. Studies suggest that treatments that reduce psychological distress improve long-term outlook in people with heart disease, including after a heart attack. Evidence indicates that stress management programs may reduce the risk of heart attacks by up to 75% in people with heart disease. Specific stress management techniques may help some problems but not others. For example, acupuncture in one study helped people with heart failure but had no effect on blood pressure. Relaxation methods, on the other hand, may help people with high blood pressure.

One survey revealed that men who had a more intense response to stressful situations, such as waiting in line or problems at work, were more likely to have strokes than those who did not report such distress. In some people, prolonged or frequent mental stress causes an exaggerated increase in blood pressure.

Chronic stress affects the immune system in complicated ways, and may have various results.

Susceptibility to Infections. Chronic stress appears to blunt the immune system's response to infections, and may even impair a person's response to immunizations. Several studies have shown that people under chronic stress have low white blood cell counts and are vulnerable to colds. Once a person catches a cold or flu, stress can make symptoms worse. People who carry the herpes virus or HIV may be more susceptible to viral activation following exposure to stress. Even more serious, some research has found that HIV-infected men with high stress levels progress more rapidly to AIDS when compared to those with lower stress levels.

Inflammatory Response. Some evidence suggests that chronic stress triggers an over-production of certain immune factors called cytokines. In excess levels, these chemicals can have very damaging effects. A recent study found that students unable to cope with stress had high levels of TNF-alpha, an inflammatory cytokine. Such findings may partly explain the association between chronic stress and numerous diseases, including heart disease and asthma.

Whether or not stress causes or aggravates cancer is not entirely clear. One study reported no association between stressful life events and recurrence in women who had been treated for breast cancer. Nevertheless, some animal studies suggest that lack of control over stress (not simply stress itself) had negative effects on immune function and contributed to tumor growth.

That being said, a 2007 study found that stress activates a gene that may cause metastatic cancer, as measured by increasing levels of the marker AGR2.

Although stress reduction techniques have no effect on survival rates, studies show that they are very helpful in improving a cancer patient's quality of life. Stress is also known to be one cause of hyponatremia (low plasma sodium levels) in cancer patients. Fortunately, this imbalance can be corrected with drugs called AVP-receptor agonists, developed for use in heart failure.

The brain and intestines are strongly related, and are controlled by many of the same hormones and parts of the nervous system. Indeed, some research suggests that the gut itself has features of a primitive brain. It is not surprising then that prolonged stress can disrupt the digestive system, irritating the large intestine and causing diarrhea, constipation, cramping, and bloating. Excessive production of digestive acids in the stomach may cause a painful burning.

Irritable Bowel Syndrome. Irritable bowel syndrome (or spastic colon) is strongly related to stress. With this condition, the large intestine becomes irritated, and its muscular contractions are spastic rather than smooth and wave-like. The abdomen is bloated, and the patient experiences cramping and alternating periods of constipation and diarrhea. Sleep disturbances due to stress can make irritable bowel syndrome even worse.

Peptic Ulcers. It is now well-established that most peptic ulcers are either caused by the H. pylori bacteria or the use of nonsteroidal anti-inflammatory (NSAID) medications (such as aspirin and ibuprofen). Nevertheless, studies still suggest that stress may predispose someone to ulcers, or sustain existing ulcers. Some experts estimate that social and psychological factors play some contributing role in 30 - 60% of peptic ulcer cases, whether they are caused by H. pylori or NSAIDs. In any case, some experts believe that the anecdotal relationship between stress and ulcers is so strong that attention to psychological factors is still warranted.

Inflammatory Bowel Disease. Although stress is not a cause of inflammatory bowel disease (Crohn's disease or ulcerative colitis), there are reports of an association between stress and symptom flare-ups. One study, for example, found that while short-term (over the previous month) stress did not significantly exacerbate ulcerative colitis symptoms, long-term perceived stress tripled the rate of flare-ups compared to patients who did not report feelings of stress.

Stress can have varying effects on eating problems and weight.

Weight Gain. Often stress is related to weight gain and obesity. Many people develop cravings for salt, fat, and sugar to counteract tension. As a result, they gain weight. Weight gain can occur even with a healthy diet, however, in some people exposed to stress. In addition, the weight gained is often abdominal fat, a predictor of diabetes and heart problems.

The release of cortisol, a major stress hormone, appears to encourage abdominal fat and may be the primary connection between stress and weight gain. Cortisol is a glucocorticoid. These hormones, along with insulin, appear to be responsible for stress-related food cravings. A 2005 study showed that hormonally induced cravings for "comfort foods" may have a biological benefit for managing stress. Eating comfort foods appears to reduce the negative hormonal and behavioral changes associated with stress, which might lessen the impact of stress on an individual. Carbohydrates in particular have been found to significantly increase levels of tryptophan and large neutral amino acids. This produces serotonin, which improves mood and performance under stress.

A 2007 study proposes a "reward-based stress eating" model. In this theory, stress and tasty, high-calorie foods cause the brain to make chemicals called endogenous opioids. These neurotransmitters help protect against the harmful effects of stress by slowing activity of a brain process called the hypothalamic-pituitary-adrenal (HPA) axis, thus weakening the stress response. Repeated stimulation of the reward pathways through stress-induced HPA stimulation, eating tasty food, or both, may lead to changes in the brain that cause compulsive overeating.

Weight Loss. Some people suffer a loss of appetite and lose weight during periods of stress. In rare cases, stress may trigger hyperactivity of the thyroid gland, stimulating appetite but causing the body to burn up calories at a faster than normal rate.

Eating Disorders. Chronically elevated levels of stress chemicals have been observed in patients with anorexia and bulimia. Some studies, however, have not found any strong link between stress and eating disorders. More work is needed to determine if changes in stress hormones are a cause or result of eating disorders.

Chronic stress has been associated with the development of insulin resistance, a condition in which the body is unable to use insulin effectively to regulate glucose (blood sugar). Insulin resistance is a primary factor in diabetes. In the Healthy Women Study, a large population of healthy women was studied for 15 years. Very stressful life events and severe depression greatly increased the risk of developing insulin resistance.

In another study of more than 33,000 Swedish workers, the development of type 2 diabetes was strongly correlated with work stress and low emotional support. However, the effect was seen in women, but not in men.

Stress can also exacerbate existing diabetes by impairing the patient's ability to manage the disease effectively.

Researchers are attempting to find the relationship between pain and emotion, but the area is complicated by many factors, including effects of personality types, fear of pain, and stress itself. A recent study suggests that chronic pain may impair the action of neutrophils, thereby weakening the immune response.

Muscular and Joint Pain. Stress may intensify chronic pain caused by arthritis and other conditions. According to a study on patients with rheumatoid arthritis, however, stress management techniques do not appear to have much effect on arthritic pain. Psychological distress also plays a significant role in the severity of back pain. Some studies have clearly associated job dissatisfaction and depression to back problems, although it is still unclear if stress is a direct cause of the back pain.

Headaches. Tension-type headaches are highly associated with stress and stressful events. Sometimes the headache does not start until long after the stressful event has ended. Additionally, stress can contribute to the development of headaches or cause headaches to occur more often.

Some research suggests that people who suffer from tension-type headaches may have some biological predisposition for translating stress into muscle contractions. Among the wide range of possible migraine triggers is emotional stress (although the headaches often erupt after the stress has eased). One study suggested that women with migraines tend to have personalities that over-respond to stressful situations.

The tensions of unresolved stress frequently cause insomnia, generally keeping the stressed person awake or causing awakening in the middle of the night or early morning. This appears to be due to the fact that stress causes physiological arousal during non-rapid eye movement (NREM) sleep.

Sexual Function. Stress can lead to diminished sexual desire and an inability to achieve orgasm in women. Stress response can cause androgen levels to drop, causing temporary impotence in men. Part of the stress response involves the release of brain chemicals that constrict the smooth muscles of the penis and its arteries. This constriction reduces the blood flow into and increases the blood flow out of the penis, which can prevent erection.

Premenstrual Syndrome. Some studies indicate that the stress response in women with premenstrual syndrome may be more intense than in those without the syndrome.

Fertility. Stress may even affect fertility. Stress hormones have an impact on the hypothalamus gland, which produces reproductive hormones. Severely elevated cortisol levels can even shut down menstruation. One small study reported a significantly higher incidence of pregnancy loss in women who had both high stress and prolonged menstrual cycles. Another reported that women with stressful jobs had shorter periods than women with low-stress jobs.

Effects on Pregnancy. Old wives' tales about a pregnant woman's emotions affecting her baby may have some credence. Stress may cause physiologic alterations, such as increased adrenal hormone levels or resistance in the arteries, which may interfere with normal blood flow to the placenta. Maternal stress during pregnancy has been linked to a higher risk for miscarriage, lower birth weights, and increased incidence of premature births. Some evidence also suggests that stress experienced by expectant mothers can even influence the way in which the baby's brain and nervous system will react to stressful events. Indeed, one study found a higher rate of crying and low attention in infants of mothers who had been stressed during pregnancy.

Menopause. A drop in estrogen levels during perimenopause and menopause may be responsible for changes in mood precipitated by stress. Estrogen replacement therapy can soften this response to stressful events.

Stress affects the brain, particularly memory, but the effects vary widely depending on whether the stress is acute or chronic.

Effect of Acute Stress on Memory and Concentration. Studies indicate that the immediate effect of acute stress impairs short-term memory, particularly verbal memory. On the plus side, high levels of stress hormone during short-term stress have been associated with enhanced memory storage and greater concentration on immediate events. The difference in effect may be due to how cortisol impacts glucocorticoid receptors in the hippocampus and prefrontal cortex. In a study of 20 men and 20 women, those whose cortisol levels increased in response to unpleasant, emotionally arousing photos had less memory recall later than those whose cortisol levels did not rise.

Effect of Chronic Stress on Memory. If stress becomes chronic, sufferers often experience loss of concentration at work and home, and they may become inefficient and accident-prone. In children, the physiologic responses to chronic stress can clearly inhibit learning. Chronic stress in older people may play an even more important role in memory loss than the aging process. In one study, for example, older adults with low stress hormone levels tested as well as younger adults in cognitive tests; those with higher stress levels tested 20 - 50% lower.

Studies have connected long-term exposure to excess amounts of cortisol (a major stress hormone) to shrinking of the hippocampus, the brain’s memory center. For example, two studies reported that groups who suffered from post-traumatic stress disorder (Vietnam veterans and women who suffered from sexual abuse) displayed up to 8% shrinking of the hippocampus. It is not yet known if this shrinking is reversible.

Allergies. Stress has been related to skin allergies. Some research suggests that stress, not indoor pollutants, may actually be a cause of the so-called sick-building syndrome. Sick-building syndrome produces allergy-like symptoms, such as eczema, headaches, asthma, and sinus problems, in office workers.

Compulsive Hoarding. People with obsessive-compulsive disorder (OCD) and compulsive hoarding are far more likely to have experienced a traumatically stressful event than people with OCD who are not hoarders. Hoarders who have experienced traumatic events have significantly more severe hoarding than those who have not been traumatized. The strongest association with traumatic stress is found in the clutter factor of compulsive hoarding, rather than in difficulty discarding objects.

Chronic Fatigue. Stress increases the risk of developing chronic fatigue syndrome, although studies suggest that high levels of emotional instability may genetically predispose someone to the syndrome.

Skin Disorders. Stress plays a role in worsening numerous skin conditions, including hives, psoriasis, acne, rosacea, and eczema, and is one of the most common causes of eczema. Unexplained itching may also be caused by stress. Evidence suggests that experiencing the stress of a traumatic event (parental divorce or separation, or a severe disease in a family member) before age 2 increases the risk of developing eczema.

Unexplained Hair Loss (Alopecia Areata). Alopecia areata is hair loss that occurs in localized (individual) patches. The cause is unknown, but stress is suspected as a player in this condition. For example, hair loss often occurs during periods of intense stress, such as mourning.

Teeth and Gums. Stress has now been implicated in increasing the risk for periodontal disease, which is disease in the gums that can cause tooth loss.

People under chronic stress often turn to alcohol abuse or tobacco use for relief. The damage these self-destructive habits cause under ordinary circumstances is compounded by the physiological effects of stress itself. Many people also resort to abnormal eating patterns or passive activities, such as watching television. The results of a national survey, released in February 2006, show that: "Americans engage in unhealthy behaviors such as comfort eating, poor diet choices, smoking and inactivity to help deal with stress."

Alcohol affects receptors in the brain that reduce stress. Lack of nicotine increases stress in smokers, which creates a cycle of dependency on smoking. One study indicated that nicotine has calming effects in women but not in men. In fact, in the study, smoking increased aggression in men.

The cycle is self-perpetuating: a sedentary routine, an unhealthy diet, alcohol abuse, and smoking all promote heart disease. They also interfere with sleep patterns, and lead to increased rather than reduced tension levels. Drinking four or five cups of coffee, for example, can cause changes in blood pressure and stress hormone levels similar to those produced by chronic stress. Animal fats, simple sugars, and salt are known contributors to health problems.

Conditions with Similar Symptoms

The physical symptoms of anxiety disorders mirror many symptoms of stress, including:

A fast heart rate
Rapid, shallow breathing
Increased muscle tension

Anxiety is an emotional disorder, however, and is characterized by feelings of apprehension, uncertainty, fear, or panic. Unlike stress, the triggers for anxiety are not necessarily or even usually associated with specific stressful or threatening conditions. Some individuals with anxiety disorders have numerous physical complaints, such as headaches, gastrointestinal disturbances, dizziness, and chest pain. Severe cases of anxiety disorders are debilitating, and interfere with career, family, and social spheres.

Depression can be a disabling condition, and, like anxiety disorders, may result from chronic stress. A 2005 study of Canadian workers found that individuals with a high level of work-related stress are more than twice as likely to experience a major depressive episode, compared with people under less stress. Evidence also suggests that certain people may be genetically susceptible to depression after stressful life events. Depression also mimics some of the symptoms of stress, including changes in appetite, sleep patterns, and concentration. Serious depression, however, is distinguished from stress by feelings of sadness, hopelessness, loss of interest in life, and, sometimes, thoughts of suicide. Acute depression is also accompanied by significant changes in the patient's functioning. Professional therapy may be needed in order to determine if depression is caused by stress, or if it is the primary problem.

Post-traumatic stress disorder (PTSD) is a reaction to a very traumatic event, and it is actually classified as an anxiety disorder. The event that brings on PTSD is usually outside the norm of human experience, such as intense combat or sexual assault. The patient struggles to forget the traumatic event and frequently develops emotional numbness and event-related amnesia. Often, however, there is a mental flashback, and the patient re-experiences the painful circumstance in the form of dreams and disturbing thoughts and memories. These thoughts and dreams resemble or recall the trauma. Other symptoms may include lack of pleasure in formerly enjoyed activities, hopelessness, irritability, mood swings, sleep problems, inability to concentrate, and an excessive startle-response to noise.

Treatment

Perhaps the best general approach for treating stress can be found in the elegant passage by Reinhold Niebuhr, "Grant me the courage to change the things I can change, the serenity to accept the things I can't change, and the wisdom to know the difference." The process of learning to control stress is life-long, and will not only contribute to better health, but a greater ability to succeed in one's own agenda.

Stress can be a factor in a variety of physical and emotional illnesses, which should be professionally treated. Many stress symptoms are mild and can be managed by over-the-counter medications (for example, aspirin, acetaminophen, or ibuprofen for tension headaches; antacids, anti-diarrhea medications, or laxatives for mild stomach distress). A physician should be consulted, however, for physical symptoms that are out of the ordinary, particularly those that get worse or wake a person up at night. A mental health professional should be consulted for unmanageable acute stress or for severe anxiety or depression. Often short-term therapy can resolve stress-related emotional problems.

In choosing specific strategies for treating stress, several factors should be considered.

No single method is always successful: A combination of approaches is generally most effective.
What works for one person does not necessarily work for someone else.
Stress can be positive as well as negative. Appropriate and controllable stress provides interest and excitement and motivates the individual to greater achievement. A lack of stress may lead to boredom and depression.

Stress may play a part in making people vulnerable to illness. A physician or psychologist should be consulted if there are any indications of accompanying medical or psychological conditions, such as heart symptoms, significant pain, anxiety, or depression.

People often succeed in relieving stress for the short term. However, they go back to previous ways of stressful thinking and behaving because of outside pressure, long-held beliefs, or habits. The following are some obstacles to managing stress:

The fight or flight urge: The very idea of relaxation can feel threatening, because it is perceived as letting down one's guard. For example, an over-demanding boss may put a subordinate into a psychological state of fighting-readiness, even though there is no safe opportunity for the subordinate to fight back or express anger. Stress builds up, but the worker has the illusion, even subconsciously, that the stress itself is providing safety or preparedness. For this reason, the employee does nothing to correct the condition.
Many people are afraid of being perceived as selfish if they engage in stress-reducing activities that benefit only themselves. The truth is that self-sacrifice (in the form of not reducing one’s stress) may be inappropriate and even damaging, if the person making the sacrifice is unhappy, angry, or physically unwell.
Some people believe that certain emotional responses to stress, such as anger, are natural and unchangeable features of personality. Research has shown, however, that with cognitive behavioral therapy, individuals can be taught to change their emotional reactions to stressful events.

It is essential to remember that reducing stress and staying relaxed clears the mind, so it can begin appropriate actions to get rid of the stress-ridden conditions.

Although treating stress cannot cure medical problems, stress management can be a very important part of medical treatment. Specific stress reduction approaches may benefit different medical problems. For example, acupuncture in one study helped reduce harmful heart muscle actions in people with heart failure, but it had no effect on blood pressure. Relaxation methods, on the other hand, may help people with high blood pressure. Stress reduction may improve well-being and quality of life for many patients who are experiencing stress because of severe or chronic medical conditions.

Important Note: Never use stress reduction techniques as the only treatment, or in place of proven treatments, for any medical condition.

Risk Factors

At some point in their lives virtually everyone will experience stressful events or situations that overwhelm their natural coping mechanisms. In one poll, 89% of respondents indicated that they had experienced serious stress in their lives. Some people are simply biologically prone to stress. Many outside factors influence susceptibility as well.

Conditions Most Likely To Produce Stress-Related Health Problems. Conditions that are most likely to be associated with stress and negative physical effects include the following:

An accumulation of persistent stressful situations, particularly those that a person cannot easily control (for example, high-pressured work plus an unhappy relationship)
Persistent stress following a severe acute response to a traumatic event (such as an automobile accident)
Acute stress accompanying serious illness, such as heart disease

Factors That Influence the Response to Stress. People respond to stress differently, depending on different factors:

Early nurturing: Abusive behavior towards children may cause long-term abnormalities in the hypothalamus-pituitary system, which regulates stress.
Personality traits: Certain people have personality traits that cause them to over-respond to stressful events.
Genetic factors: Some people have genetic factors that affect stress, such as having a more or less efficient relaxation response. One study found a genetic abnormality in serotonin regulation that was connected with a heightened reaction of heart rates and blood pressure in response to stress. (Serotonin is a brain chemical involved with feelings of well-being.)
Immune regulated diseases: Certain diseases that are associated with immune abnormalities (such as rheumatoid arthritis or eczema) may actually weaken a response to stress.
The length and quality of stressors: Naturally, the longer the duration and more intense the stressors, the more harmful the effects.

Individuals at Higher Risk for Stress. Studies indicate that the following people are more vulnerable to the effects of stress than others:

Older adults: As people age, achieving a relaxation response after a stressful event becomes more difficult. Aging may simply wear out the systems in the brain that respond to stress, so that they become inefficient. The elderly, too, are very often exposed to major stressors such as medical problems, the loss of a spouse and friends, a change in a living situation, and financial worries. No one is immune to stress, however, and it may simply go unnoticed in the very young and old.
Women in general and working mothers specifically: Working mothers, regardless of whether they are married or single, face higher stress levels and possibly adverse health effects, most likely because they bear a greater and more diffuse work load than men or other women. This has been observed in women in the U.S. and in Europe. Such stress may also have a domino and harmful effect on their children. It is not clear, however, if stress has the same adverse effects on women's hearts as it does on men's.
Less educated individuals.
Divorced or widowed individuals: Numerous studies indicate that unmarried people generally do not live as long as their married contemporaries.
Anyone experiencing financial strain, particularly long-term unemployed and those without health insurance.
People who are isolated or lonely.
People who are targets of racial or sexual discrimination.
People who live in cities.

Children are frequent victims of stress because they are often unable to communicate their feelings accurately. They also have trouble communicating their responses to events over which they have no control. Certain physical symptoms, notably repeated abdominal pain without a known cause, may be indicators of stress in children.

Various conditions can affect their susceptibility to stress.

Low Birth Weight. One study reported that low birth weight and slow growth up until age 7 was related to stress in adulthood.

Parental Stress. Parental stress, especially in mothers, is a particularly powerful source of stress in children, even more important than poverty or overcrowding. In a 2002 study, for example, young children of mothers who were highly stressed (particularly if they were depressed) tended to be at high risk for developing stress-related problems. This was especially true if the mothers were stressed during both the child's infancy and early years. Some evidence even supports the old idea that stress during pregnancy can have adverse effects on the infant's mood and behavior. Older children with stressed mothers may become aggressive and anti-social. One study suggested that stress-reduction techniques in parents may improve their children's behavior.

Gender Differences in Adolescent Stress. Adolescent boys and girls experience equal amounts of stress, but the source and effects may differ. Girls tend to become stressed from interpersonal situations, and stress is more likely to lead to depression in girls than in boys. For boys, however, specific events, such as changing schools or getting poor grades, appear to be the major sources of stress.

A report issued in October 2006 by the American Academy of Pediatrics recommends more unstructured play time for children. The report notes that today’s overscheduled, hurried lifestyle that many children experience is a source of stress and anxiety in some children.

In a 1999 study of 46,000 workers, health care costs were 147% higher in workers who were stressed or depressed than in others who were not. Furthermore, according to one survey, 40% of American workers describe their jobs as very stressful, making job-related stress an important and preventable health hazard.

Several studies are now suggesting that job-related stress is as great a threat to health as smoking or not exercising. Stress impairs concentration, causes sleeplessness, and increases the risk for illness, back problems, accidents, and lost time from work. Work stress can lead to harassment or even violence while on the job. At its most extreme, chronic stress places a burden on the heart and circulation that in some cases may be fatal. The Japanese even have a word for sudden death due to overwork, karoushi.

Not all work stress is harmful. However, studies suggest the following job-related stressors may increase people's -- particularly men's -- health risks:

Having no say in decisions that affect one's responsibilities
Unrelenting and unreasonable performance demands
Lack of effective communication and conflict-resolution methods among workers and employers
Lack of job security
Night-shift work, long hours, or both
Too much time spent away from home and family
Wages not matching levels of responsibility

Reducing Stress on the Job. Many institutions within the current culture, while paying lip service to stress reduction, put intense pressure on individuals to behave in ways that increase tension. Yet, there are numerous effective management tools and techniques available to reduce stress. Furthermore, treatment for work-related stress has proven benefits for both the employee and employer. In one study, at the end of 2 years, a company that instituted a stress management program saved nearly $150,000 in workers compensations costs (the cost of the program was only $6,000). Other studies have reported specific health benefits resulting from workplace stress-management programs. In one of the studies, workers with hypertension experienced reduced blood pressure after even a brief (16-hour) program that helped them manage stress behaviorally.

In general, however, few workplaces offer stress management programs, and it is usually up to the employee to find their own ways to reduce stress. Here are some suggestions:

Seek out someone in the Human Resources department or a sympathetic manager and communicate concerns about job stress. Work with them in a non-confrontational way to improve working conditions, letting them know that productivity can be improved if some of the pressure is off.
Establish or reinforce a network of friends at work and at home.
Restructure priorities and eliminate unnecessary tasks.
Learn to focus on positive outcomes.
If the job is unendurable, plan and execute a career change. Send out resumes or work on transfers within the company.
If this isn't possible, be sure to schedule daily pleasant activities and physical exercise during free time.

It may be helpful to keep in mind that bosses are also victimized by the same stressful conditions they are imposing. For example, in one study of male managers in three Swedish companies, those who worked in a bureaucracy had greater stress-related heart risks than those who worked in companies with social supports.

Caregivers of Family Members. Studies show that caregivers of physically or mentally disabled family members are at risk for chronic stress. One study reported that overall mortality rates were over 60% higher in caregivers who were under constant stress. Spouses caring for a disabled partner are particularly vulnerable to a range of stress-related health threats, including influenza, depression, heart disease, and even poorer survival rates. Caring for a spouse with even minor disabilities can induce severe stress.

Specific risk factors that put caregivers at higher risk for severe stress, or stress-related illnesses, include:

Caregiving wives: Some studies suggest that wives experience significantly greater stress from caregiving than husbands do.
Having a low income.
Being African-American: African-American people tend to be in poorer physical health, and have lower incomes, than Caucasians. They therefore face greater stress as caregivers to their spouses than their white counterparts.
Living alone with the patient.
Helping a highly dependent patient.
Having a difficult relationship with the patient.

Intervention programs that are aimed at helping the caregiver approach the situation positively can reduce stress, and help the caregiver maintain a positive attitude. A 2002 program also demonstrated that moderate-intensity exercise was very helpful in reducing stress and improving sleep in caregivers.

Health Professional Caregivers. Caregiving among the health professionals is also a high risk factor for stress. One study, for example, found that registered nurses with low job control, high job demands, and low work-related social support experienced very dramatic health declines, both physically and emotionally.

People who are less emotionally stable or have high anxiety levels tend to experience specific events as more stressful than others. Some doctors describe an exaggerated negative response to stress as "catastrophizing" the event (turning it into a catastrophe). Nevertheless, a 2003 study of patients with anxiety disorder did not find any differences in actual physical response to stress (heart rate, blood pressure, release of stress hormones) compared to people without anxiety.

The lack of an established network of family and friends predisposes one to stress disorders and stress-related health problems, including heart disease and infections. A study, meanwhile, reported that older people who maintain active relationships with their adult children are buffered against the adverse health effects of chronic stress-inducing situations, such as low income or lower social class. Another study suggested this may be because people who live alone are unable to discuss negative feelings as a means to relieve their stress.

Studies of people who remain happy and healthy despite many life stresses conclude that most have very good networks of social support. One study indicated that support even from strangers reduced blood pressure surges in people undergoing a stressful event. Many studies suggest that having a pet helps reduce medical problems aggravated by stress, including heart disease and high blood pressure.

Lifestyle Changes

A healthy lifestyle is an essential companion to any stress-reduction program. General health and stress resistance can be enhanced by regular exercise, a diet rich in a variety of whole grains, vegetables, and fruits, and by avoiding excessive alcohol, caffeine, and tobacco.

Of interest, a 2003 study suggested that fish oil, which has been associated with a lower risk for heart disease and stroke, may blunt some of the harmful effects of mental stress on the heart.

In one study, high doses of vitamin C reduced stress levels and blood pressure. The doses given were higher than the recommended upper limit of 2,000 mg per day. High doses may cause headaches and diarrhea. Long-term use increases risk for kidney stones and has other adverse effects in specific individuals.

Exercise in combination with stress management techniques is extremely important for many reasons:

Exercise is an effective distraction from stressful events.
Exercise may directly blunt the harmful effects of stress on blood pressure and the heart (exercise protects the heart in any case).

Usually, a varied exercise regime is more interesting, and thus easier to stick to. Start slowly. Strenuous exercise in people who are not used to it can be very dangerous and any exercise program should be discussed with a physician. In addition, half of all people who begin a vigorous training regime drop out within a year. The key is to find activities that are exciting, challenging, and satisfying. The following are some suggestions:

Sign up for aerobics classes at a gym.
Brisk walking is an excellent aerobic exercise that is free and available to nearly anyone. Even short brisk walks can relieve bouts of stress.
Swimming is an ideal exercise for many stressed people, including pregnant women, individuals with musculoskeletal problems, and those who suffer exercise-induced asthma.
Yoga or Tai Chi can be very effective, combining many of the benefits of breathing, muscle relaxation, and meditation while toning and stretching the muscles. The benefits of yoga may be considerable. Numerous studies have found it beneficial for many conditions in which stress is an important factor, such as anxiety, headaches, high blood pressure, and asthma. It also elevates mood and improves concentration and the ability to focus.

As in other areas of stress management, making a plan and executing it successfully develops feelings of mastery and control, which are very beneficial in and of themselves. Start small. Just 10 minutes of exercise three times a week can build a good base for novices. Gradually build up the length of these every-other-day sessions to 30 minutes or more.

Cognitive-behavioral techniques (CBT) are among the most effective ways of reducing stress. A 2005 study found that CBT training can have a long-term impact one’s ability to cope with stress. In the study, participants received CBT training and were exposed to a stressful situation 4 months later. The participants who had received CBT training had significantly less stress-induced cortisol responses compared with individuals who had received no stress management training. This effect was observed in both men and women, although the CBT had a greater effect on men. CBT may be particularly helpful when the source of stress is chronic pain or a chronic disease. In fact, in a study of patients with HIV, CBT was more helpful than support groups for improving well-being and quality-of-life.

A typical CBT approach includes identifying sources of stress, restructuring priorities, changing one's response to stress, and finding methods for managing and reducing stress.

Identifying Sources of Stress. One key component in most CBT approaches is a diary that keeps an informal inventory of daily events and activities. While this exercise might itself seem stress producing (and yet one more chore), it need not be done in painstaking detail. A few words accompanying a time and date are usually enough to serve as reminders of significant events or activities.

The first step is to note activities that put a strain on energy and time, trigger anger or anxiety, or precipitate a negative physical response (such as a sour stomach or headache).

Also note positive experiences, such as those that are mentally or physically refreshing or produce a sense of accomplishment.

After a week or two, try to identify two or three events or activities that have been significantly upsetting or overwhelming.

Questioning the Sources of Stress. Individuals should then ask themselves the following questions:

Do these stressful activities meet my goals or someone else's?
Have I taken on tasks that I can reasonably accomplish?
Which tasks are under my control and which ones aren't?

Restructuring Priorities: Adding Stress Reducing Activities. The next step is to attempt to shift the balance from stress-producing to stress-reducing activities. Eliminating stress is rarely practical or feasible, but there are many ways to reduce its impact.

Consider as many relief options as possible. Examples include:

Listen to music. Music is an effective stress reducer in both healthy individuals and people with health problems. In one study, for example, students who listened to a well-known gentle classical piece of music during a stressful task had reduced feelings of anxiety, heart rate, and blood pressure.
Take long weekends or, ideally, vacations.
If the source of stress is in the home, plan times away, even if it is only an hour or two a week.
Replace unnecessary time-consuming chores with pleasurable or interesting activities.
Make time for recreation. This is as essential as paying bills or shopping for groceries.
Own a pet. In a study of people with high blood pressure, pet owners had much lower blood pressure increase in response to stress than non-owners. Note that owning a pet was beneficial only for people who like animals to begin with.

Discuss Feelings. The concept of communication and letting your feelings out has been so excessively promoted and parodied that it has nearly lost its value as good psychological advice. Nevertheless, feelings of anger or frustration that are not expressed in an acceptable way may lead to hostility, a sense of helplessness, and depression.

Expressing feelings does not mean venting frustration on waiters and subordinates, boring friends with emotional minutia, or wallowing in self-pity. In fact, because blood pressure may spike when certain chronically hostile individuals become angry, some therapists strongly advise that just talking, not simply venting anger, is the best approach, especially for these people.

The primary goal is to explain and assert one's needs to a trusted individual in as positive a way as possible. Direct communication may not even be necessary. Writing in a journal, writing a poem, or composing a letter that is never mailed may be sufficient.

Expressing one's feelings solves only half of the communication puzzle. Learning to listen, empathize, and respond to others with understanding is just as important for maintaining the strong relationships necessary for emotional fulfillment and reduced stress.

Keep Perspective and Look for the Positive. Reversing negative ideas and learning to focus on positive outcomes helps reduce tension and achieve goals. The following steps, using an example of a person who is alarmed at the prospect of giving a speech, may be useful:

First, identify the worst possible outcomes (forgetting the speech, stumbling over words, humiliation, audience contempt).
Rate the likelihood of these bad outcomes happening (probably very low or that speaker wouldn't have been selected in the first place).
Envision a favorable result (a well-rounded, articulate presentation with rewarding applause).
Develop a specific plan to achieve the positive outcome (preparing in front of a mirror, using a video camera or tape recorder, relaxation exercises).
Try to recall previous situations that initially seemed negative but ended well.

Use Humor. Research has shown that humor is a very effective mechanism for coping with acute stress. Keeping a sense of humor during difficult situations is a common recommendation from stress management experts. Laughter not only releases the tension of pent-up feelings and helps keep perspective, but it appears to have actual physical effects that reduce stress hormone levels. It is not uncommon for people to recall laughing intensely even during tragic events, such as the death of a loved one, and to remember this laughter as helping them to endure the emotional pain.

Relaxation Methods. Since stress is here to stay, everyone needs to develop methods to promote the relaxation response, the natural unwinding of the stress response. Relaxation lowers blood pressure, respiration, and pulse rates, releases muscle tension, and eases emotional strains. This response is highly individualized, but there are certain approaches that seem to work.

Combinations are probably best. For example, in a study of children and adolescents with adjustment disorder and depression, a combination of yoga, a brief massage, and progressive muscle relaxation effectively reduced both feelings of anxiety and stress hormone levels. A 2005 study of organ transplant recipients showed that training in meditation and gentle yoga led to significant improvements in quality of sleep and lessened anxiety and depression.

No one should expect a total resolution of stress from these approaches, but if done regularly, these programs can be very effective.

Acupuncture. Some evidence suggests that acupuncture may also be helpful. It might even improve some physical factors associated with stress and health problems. For example, in a study of heart failure patients, acupuncture improved stress-related heart muscle activity, which could be an important benefit in these patients. However, acupuncture had no effect on stress-related blood pressure or heart rate.

Hypnosis. Hypnosis may also benefit some people with severe stress. In one study of patients with irritable bowel, stress reduction by hypnosis correlated with improvement in many bowel symptoms.


*Deep Breathing Exercises.* During stress, breathing becomes shallow and rapid. Taking a deep breath is an automatic and effective technique for winding down. Deep breathing exercises consciously intensify this natural physiologic reaction and can be very useful during a stressful situation, or for maintaining a relaxed state during the day.	Inhale through the nose slowly and deeply to the count of 10. Make sure that the stomach and abdomen expand, but the chest does not rise. Exhale through the nose, slowly and completely, also to the count of 10. To help quiet the mind, concentrate fully on breathing and counting through each cycle. Repeat five to 10 times, and make a habit of doing the exercise several times each day, even when not feeling stressed.
*Muscle Relaxation.* Muscle relaxation techniques, often combined with deep breathing, are simple to learn and very useful for getting to sleep. In the beginning it is useful to have a friend or partner check for tension by lifting an arm and dropping it. The arm should fall freely. Practice makes the exercise much more effective and produces relaxation much more rapidly. Small studies have reported beneficial effects on blood pressure in patients with high blood pressure who use this technique.	After lying down in a comfortable position without crossing the limbs, concentrate on each part of the body. Maintain a slow, deep breathing pattern throughout this exercise. Tense each muscle as tightly as possible for a count of five to 10, and then release it completely. Experience the muscle as totally relaxed and lead-heavy. Begin with the top of the head and progress downward to focus on all the muscles in the body. Be sure to include the forehead, ears, eyes, mouth, neck, shoulders, arms and hands, fingers, chest, belly, thighs, calves, and feet. Once the external review is complete, imagine tensing and releasing internal muscles.
*Meditation.* Meditation, used for many years in Eastern cultures, is now widely accepted in this country as a relaxation technique. The goal of all meditative procedures, both religious and therapeutic, is to quiet the mind (essentially, to relax thought). Small studies have suggested that regular meditation can benefit the heart and help reduce blood pressure. Better research is needed, however, to confirm such claims. Some recommend meditating for no longer than 20 minutes in the morning after awakening and then again in early evening before dinner. Even once a day is helpful. Note: Meditating before going to bed may cause some people to wake up in the middle of the night, alert and unable to return to sleep. New practitioners should understand that it can be difficult to quiet the mind, and should not be discouraged by lack of immediate results. Several techniques are available. A few are discussed here. The only potential risks from meditating are in people with psychosis, in whom meditating may trigger a psychotic event.	Mindfulness Meditation. Mindfulness is a common practice that focuses on breathing. It employs the basic technique used in other forms of meditation. Sit upright with the spine straight, either cross-legged or sitting on a firm chair with both feet on the floor, uncrossed. With the eyes closed or gently looking a few feet ahead, observe the exhalation of the breath. As the mind wanders, simply note it as a fact and returns to the "out" breath. It may be helpful to imagine your thoughts as clouds dissipating away. Transcendental Meditation (TM). TM uses a mantra (a word that has a specific chanting sound but no meaning). The person meditating repeats the word silently, letting thoughts come and go. In one study, TM was as effective as exercise in elevating mood. Mini-Meditation. The method involves heightening awareness of the immediate surrounding environment. Choose a routine activity when alone. For example: While washing dishes, concentrate on the feel of the water and dishes. Allow the mind to wander to any immediate sensory experience (sounds outside the window, smells from the stove, colors in the room). If the mind begins to think about the past or future, or fills with unformed thoughts or worries, redirect it gently back. This redirection of brain activity from your thoughts and worries to your senses disrupts the stress response and prompts relaxation. It also helps promote an emotional and sensual appreciation of simple pleasures already present in a person's life.
*Biofeedback.* Biofeedback is a technique that measures bodily functions, like breathing, heart rate, blood pressure, skin temperature, and muscle tension. By watching these measurements, you can learn how to alter these functions by relaxing or holding pleasant images in your mind.	During biofeedback, electric leads are taped to a subject's head. The person is encouraged to relax using methods such as those described above. Brain waves are measured and an audible signal is emitted when alpha waves are detected, a frequency which coincides with a state of deep relaxation. By repeating the process, subjects associate the sound with the relaxed state and learn to achieve relaxation by themselves.
*Massage Therapy.* A 2005 report that reviewed data from multiple studies showed that massage therapy decreases cortisol levels. Another 2005 study showed that massage from a stable romantic partner can reduce physiological responses to a subsequent stressful event. In the study, women who received instructed shoulder-neck-massage from their partners before being exposed to stress had lowered cortisol responses, and smaller heart rate increases after the stressful event. Interestingly, massage was more beneficial than receiving social support from the partner, indicating the power of physical touch in managing stress. Several massage therapies are available.	Many massage techniques are available, such as the following: Swedish massage is the standard massage technique. It uses long smooth strokes, and kneading and tapping of the muscles. Shiatsu applies intense pressure to the same points targeted in acupuncture. It can be painful, but people report deep relaxation afterward. Reflexology manipulates acupuncture points in the hands and feet.

Some people who experience chronic stress seek herbal or natural remedies. It should be strongly noted, however, that just as with standard drugs, so-called natural remedies can cause problems, sometimes serious ones.

Probiotics. Probiotics are helpful bacterial strains that by themselves may provide a barrier against harmful bacteria. They do so through various mechanisms, such as excreting certain acids (for example, lactate, acetate) that inhibit harmful bacteria. They may also compete with them for nutrients. Stress reduces levels of these bacteria. Research even suggests that probiotics may help maintain remission in patients with IBD. In one small study, people suffering from stress and exhaustion significantly reduced their stress symptoms and gastrointestinal complaints when they took a probiotic supplement for 6 months. The specific bacteria that might be beneficial, however, are not fully known. The most well-known probiotics are the lactobacilli strains, such as acidophilus, which is found in yogurt and other fermented milk products. Others, however, may prove to be more important, such as bifidobacteria and GG lactobacilli. Other probiotics include the lactobacilli rhamnosus, casel, plantarium, bulgaricus, and salivarius, and also Enterococcus faecium and Streptococcus thermophilus.

Aromatherapy. The smell of lavender has long been associated with a calming effect. In a Japanese study, 14 women who were put in a room with a lavender scent experienced reduced mental stress. Several aromatherapies are now used for relaxation. Use caution, however, as some of the exotic plant extracts in these formulas have been associated with a wide range of skin allergies.

Valerian. Valerian is an herb that has sedative qualities and may reduce stress and associated physical effects. This herb is on the FDA's list of generally safe products. Of note, however, the herb's effects could be dangerously increased if it is used with standard sedatives. Other interactions and long-term side effects are unknown. Side effects include vivid dreams. High doses of valerian can cause blurred vision, excitability, and changes in heart rhythm.

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, however, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been numerous reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

Special Warning on Kava. Kava has been commonly used to reduce anxiety and stress. It is now highly associated with liver injury and even liver failure in a few cases. Experts now strongly warn against its use.

People seeking relief from stress should be wary of things that promise a quick cure, or plans that include the purchase of expensive treatments. These treatments may be useless and sometimes even dangerous.

Highlights

Systematic Lupus Erythematosus (SLE)

SLE is an autoimmune disease that causes a chronic inflammatory condition. The inflammation triggered by SLE affects many organs in the body, including skin, joints, kidneys, lung, and nervous system. Women, especially African-American and Asian women, are at highest risk for developing SLE.

Symptoms and Diagnosis

Not all patients with SLE experience the same symptoms. The most common symptoms are joint pain, skin rash, and fever. Symptoms can develop slowly or appear suddenly. Many patients with SLE have “flares,” in which symptoms suddenly worsen and then disappear for long periods of time. Diagnosing SLE is complicated because symptoms vary widely and can resemble other conditions. A doctor will base an SLE diagnosis on certain specific criteria including symptom history and the results of blood tests for antinuclear antibodies.

Treatment

No drug can cure SLE, but many different drugs can help control symptoms and relieve discomfort. The choice of drugs depends on the severity of the condition as well as other factors. Patients with mild SLE may be helped by nonsteroidal anti-inflammatory drugs (NSAIDs) while patients with more severe SLE may require corticosteroids or immunosuppressants. Researchers are working to develop new drugs and treatments for SLE.

Living with SLE

Patients can make lifestyle changes to help cope with SLE. These include:

Avoid excessive sunlight exposure, and wear sunscreen (ultraviolet light is the one of the main triggers of flares).
Get plenty of rest (fatigue is another common SLE symptom).
Engage in regular light-to-moderate exercise to help fight fatigue and heart disease, and to keep joints flexible.

Introduction

Systemic lupus erythematosus (SLE) is a chronic, often life-long, autoimmune disease. It can be mild to severe, and affects mostly women. SLE may affect various parts of the body, but it most often manifests in the skin, joints, blood, and kidneys. SLE was first described in 1828. Its very name helps define the disease:

Systemic is used because the disease can affect organs and tissue throughout the body.
Lupus is Latin for wolf. It refers to the rash that extends across the bridge of the nose and upper cheekbones and was thought to resemble a wolf bite.
Erythematosus is from the Greek word for red and refers to the color of the rash.

Lupus has many different symptoms. Common ones include:

Fatigue
Joint pain or swelling
Skin rashes

Causes

Systemic lupus erythematosus is a complex disorder that occurs as a consequence of a number of independent processes and factors.

Environmental factors, such as viruses, exposure to chemicals, or sunlight trigger inflammatory or immune activity. This immune activation may begin as an appropriate response to an unwanted "invader." But, because of a combination of genetic factors, an individual with lupus develops an ongoing immune response that does not shut itself off appropriately. This leads to waxing and waning flares of inflammation that can involve various organs of the body, depending on specific features of this self-perpetuating immune response in individual patients.

The exact combination of genes that predispose individuals to SLE may differ somewhat from patient to patient, but probably share certain common features which tend to impair the ability of the body to get rid of immune-triggering particles and which tend to prolong or increase the degree of immune responsiveness to these triggers.

A major characteristic of lupus is that it is an autoimmune response in which immune factors, called autoantibodies, attack the person's own cells. Some autoantibodies are normal in a well-balanced immune system, and serve various roles to help the body dispose of wastes, protect from infectious invaders, and to keep blood vessels clear. In healthy people, autoantibodies tend to be well-regulated and well "masked," or covered up, until needed. Therefore, it is probably the high activity and high detectability of autoantibodies that makes lupus unique, not the fact that they exist.

The Normal Immune System Response. The inflammatory process is a byproduct of the activity of the body's immune system, which fights infection and heals wounds and injuries:

When an injury or an infection occurs, white blood cells are mobilized to rid the body of any foreign proteins, such as a virus.
The masses of blood cells that gather at the injured or infected site produce factors to fight any infections.
In the process, the surrounding area becomes inflamed and some healthy tissue is injured. The immune system is then called upon to repair wounds by clotting any bleeding blood vessels and initiating fiber-like patches to the tissue.
Under normal conditions, the immune system has special factors that control and limit this inflammatory process.

The Infection Fighters. B cells and T cells are two important components of the immune system that play a role in the inflammation associated with lupus. Both B cells and T cells belong to a family of immune cells called lymphocytes. Lymphocytes help fight infection.

B cells and T cells are involved in the immune system's response to infection. Antigens are foreign bodies (such as bacteria and viruses) that stimulate the immune system to produce autoantibodies. When a T cell recognizes an antigen it will produce chemicals (cytokines) that cause B cells to multiply and release many immune proteins (antibodies). These antibodies circulate widely in the bloodstream, recognizing the foreign particles and triggering inflammation in order to rid the body of the invasion.

An antigen is a substance that can provoke an immune response. Typically antigens are substances not usually found in the body.

For reasons that are still not completely understood, both the T cells and B cells become overactive in lupus patients. In lupus, a complex interaction between activated immune cells and an impaired antigen-elimination process leads to a greater than normal range of what the antibodies recognize. Eventually, antibodies are made that recognize more of the body's own tissues in a stronger or more persistent manner than is healthy, and inflammatory responses are mounted in these tissues.

Autoantibodies. In the majority of patients with SLE, antinuclear antibodies (ANA) are detectable. Such autoantibodies may be present in individuals up to 7 years prior to their developing symptoms of lupus. Some subtypes of ANA are found in lupus patients and only rarely in people without lupus. These include:

Anti-ds DNA. An autoantibody called anti-double stranded DNA (anti-ds DNA) may play an important role in some lupus patients.
Anti-Sm antibodies. This antibody is found most often in lupus patients of African descent and is almost never detected in people without lupus.
Anti-Ro (SSA) and Anti-La (SSB)
Antiphospholipid antibodies

Cytokines. Most immune cells secrete or stimulate the production of powerful immune factors called cytokines. In small amounts, cytokines are indispensable for maintaining the balance of the body during immune responses, including:

Infections
Injuries
Tissue repair
Blood clotting
Clearing of debris from inflamed blood vessels
Other aspects of healing.

If overproduced, however, they can cause serious damage, including dangerous levels of inflammation and cellular injury. Specific cytokines called interferons and interleukins play a critical role in SLE by regulating the secretion of autoantibodies by B cells.

Complement. Another immune factor of high interest in SLE is the complement system. This is comprised of more than 30 proteins and is important for defending and regulating the immune response. Inherited deficiencies in certain complement components (C1q, C1r, C1s, C4, and C2) have long been associated with SLE.

Researchers estimated that 20 - 100 different genetic factors may be involved in the alterations of the immune system set point that could make a person susceptible to SLE.

Research published in 2003 identified a particular set of genes, now commonly called the "interferon signature," that is activated by interferon in patients with severe lupus. This discovery may help doctors identify patients at particular risk for severe disease before they develop symptoms.
A genetic risk factor for lupus in African-American women has been identified.
Other research has identified defects in genes that regulate apoptosis, the natural process by which cells self-destruct.
An abnormal gene identified in some patients with SLE promotes the build-up of immune complexes that can cause kidney damage. HLA (human leukocyte antigen) is a protein that presents antigens to T cells by holding them up from the surface of macrophages or other antigen-presenting cells. Among the types of HLA associated with lupus are HLA-DR2, -DR3, -A1, -B8, and DMA-0104.

In genetically susceptible people, there are various external factors that can provoke an immune response. Possible SLE triggers include colds, fatigue, stress, chemicals, sunlight, and certain drugs.

Viruses. Blood tests reveal that patients with SLE are more likely to have been exposed to certain viruses than the general population. These viruses include the Epstein-Barr virus (the cause of mononucleosis), cytomegalovirus, and parvovirus-B1.

Results from a 2005 study, conducted by researchers at the National Institute of Environmental Health Sciences, suggested a strong association between Epstein-Barr virus (EBV) and increased risk of lupus, particularly for African-Americans. The association was not as strong for whites, but increased with age (patients over 50 years of age had four times higher risk).

The researchers also observed that a genetic variation in CTLA-4, a protein that helps regulate T cell immune system response, appeared to modify the risk of lupus associated with EBV-IgA antibodies. Therefore, an individual’s CTLA-4 genotype could determine the immune system’s responsiveness in fighting repeat episodes of EBV infection.

Some research suggests that different viruses may imprint specific types of SLE. For instance cytomegalovirus may affect blood vessels and cause problems such as Raynaud's phenomenon or blood abnormalities, but may not affect the kidney as much. These are speculations, however, and not a proven association.

Sunlight. Ultraviolet (UV) rays found in sunlight are important SLE triggers. When they bombard the skin, they can alter the structure of DNA in cells below the surface. The immune system may perceive these altered skin cells as foreign and trigger an autoimmune response against them. UV light is categorized as UVB or UVA depending on the length of the wave.

UVB are short waves (280 - 320 nm). The shorter the wavelengths, the more damage they do.
UVA are longer waves (320 - 400 nm). Some research suggests that UVA wavelengths in the longest range, known as UVA1 (340 - 400 nm), may actually repair DNA and normalize immune responses.

Chemicals. Clusters of SLE cases have occurred in populations with high exposure to certain chemicals. Chlorinated pesticides and crystalline silica are two suspects. A number of other chemicals are under investigation. However, it is very difficult to determine a causal role for any specific chemicals. (Silicone breast implants have been under intense scrutiny as a possible trigger of autoimmune diseases, including SLE. The weight of evidence to date, however, finds no support for this concern.) Some drugs have been associated with a temporary lupus syndrome (drug-induced lupus), which resolves when these drugs are stopped.

Hormones. Cytokines, major immune factors that are active in SLE, are directly affected by sex hormones. In general, estrogen enhances antibody production, and testosterone reduces antibody production, although their exact role in SLE may be more complicated than that since there are various ways in which each hormone might influence various immune cells. Women with SLE may have lower levels of several active male hormones (androgens), and some men who are affected by SLE may also have abnormal androgen levels.

Premature menopause, and its accompanying symptoms (such as hot flashes), is common in women with SLE. Hormone replacement therapy (HRT), which is used to relieve these symptoms, increases the risk for blood clots and heart problems. It is not clear whether HRT triggers SLE flares. Women should discuss with their doctors whether HRT is an appropriate and safe choice. Guidelines recommend that women who take HRT use the lowest possible dose for the shortest possible time. Women with SLE who have active disease, antiphospholipid antibodies, or a history of blood clots or heart disease should not use HRT.

Oral Contraceptives. Female patients with lupus used to be cautioned against taking oral contraceptives (OCs) due to the possibility that estrogen could trigger lupus flare-ups. However, recent evidence indicates that OCs are safe, at least for women with inactive or stable lupus. Women who have been newly diagnosed with lupus should avoid OCs. Lupus can cause complications in its early stages. For this reason, women should wait until the disease reaches a stable state before taking OCs. In addition, women who have a history of, or who are at high risk for, blood clots (particularly women with antiphospholipid syndrome) should not use OCs. The estrogen in OCs increases the risk for blood clots.

Risk Factors

The number of people diagnosed with lupus has more than tripled over the past four decades. Some experts believe this may simply indicate a greater degree of doctor training in recognizing the syndrome.

About 90% of lupus patients are women, most diagnosed when they are in their childbearing ages. Hormones may be an explanation. After menopause, women are only 2.5 times as likely as men to contract SLE. Flares also become somewhat less common after menopause in women who have chronic SLE.

African-Americans are three to four times more likely to develop the disease than Caucasians and to have severe complications. Hispanics and Asians are also more susceptible to the disease.

A family history plays a strong role in SLE. A brother or sister of a patient with the disorder has 20 times the risk as someone without an immediate family member with SLE.

The disease is rare in childhood. When it does occur, it is often associated with thrombotic thrombocytopenia purpura, a condition resulting from abnormally low levels of blood platelets. SLE in children may also be caused by certain medications, including minocycline and zafirlukast.

Rheumatoid Arthritis. Studies have investigated the relationship among hormones, SLE, and rheumatoid arthritis, another autoimmune disease. Higher levels of estrogen are associated with SLE, while lower levels are associated with rheumatoid arthritis. Some research suggests that some patients, in fact, progress from one disease to the other, and that such transitions occur during major hormonal shifts, such as the onset of menopause or pregnancy.

Rheumatoid arthritis is a systemic autoimmune disease that initially attacks the lining, or synovium, of the joints.

Many prescription drugs can cause lupus-like skin symptoms. In one study, the most common drugs causing these symptoms were high blood pressure (hypertension) medications, including hydrochlorothiazide, angiotensin-converting-enzyme inhibitors, and calcium-channel blockers. About 40 different drugs have been linked to lupus onset. Anyone diagnosed with cutaneous lupus erythematosus should be sure to tell their doctors all the medications (including herbs and supplements) that they are taking.

Smoking. Smoking may be a risk factor for triggering SLE and can increase the risk for skin and kidney problems in women who have the disease.

Symptoms

SLE symptoms may develop slowly over months or years, or they may appear suddenly. Symptoms tend to be worse during winter months, perhaps because prolonged exposure to sunlight in the summer causes a gradual build-up of factors that trigger symptoms months later.

The most common symptom is joint pain, which occurs in about 90% of patients with SLE. Characteristics of this symptom vary widely:

It is often accompanied by swelling and redness.
It can last from hours to months.
It may be mild or severe.
It can occur in one joint, move from one to another, or flare erratically.
Pain often occurs in the morning and improves during the day, only to return later when the patient tires.
The joints most affected are fingers, wrists, elbows, knees, and ankles. (Joints in the spine and neck are not affected.)

Children may experience these symptoms as growing pains, and, in all patients, they may be the only symptoms for many years.

Fever occurs in 90% of patients with SLE and is usually caused by the inflammatory process of the disease, not by infection. It is low-grade except during an acute lupus crisis.

Three-quarters of patients with SLE have skin inflammation and skin lesions (ulcers, rashes, or other injured areas). About half of these lesions are photosensitive; that is, they are aggravated by ultraviolet (UV) radiation from sunlight, even from light coming through a window. (UV radiation may even trigger systemic flares in patients with SLE.)

A number of different skin conditions have been described in patients with SLE.

Discoid Lupus Erythematosus. About 20% of patients have discoid lesions. In such cases, the condition is often known as discoid lupus erythematosus (DLE). Patients with this condition may have the following skin abnormalities:

Discoid means coin-shaped, so these lesions are round and raised. They are also scaly. Untreated, the margins gradually extend outward as the center dries out and shrivels, causing severe scarring. If discoid lesions appear on the scalp, they can plug hair follicles and cause irreversible hair loss. Discoid lesions can also appear on the upper body.

Lupus, discoid -- view of lesions on the chest: This close-up picture of the neck clearly shows the typical rounded appearance of discoid lupus. The whitish appearance is caused by scaling. The two dark spots are biopsy sites and are not part of the disease.

A butterfly-shaped rash across the face may accompany this condition. This rash causes little scarring, although spidery, branching lines of swollen capillaries (the tiniest blood vessels) may appear.

Most patients with this condition have only a limited skin disorder. In only about 10% of cases does discoid lupus develop into full-blown SLE.

Subacute Cutaneous Lupus Erythematosus. Subacute cutaneous lupus erythematosus (SCLE) can cause skin lesions on parts of the body that are exposed to sunlight. These lesions do not cause scarring.

Vasculitis. Patients with SLE sometimes develop inflammation in the blood vessels (vasculitis) that may have the following effects on the skin:

Red welts may form across large areas of the body.
Sometimes deep red bumps may appear, particularly on the leg, where they may ulcerate.
In some people, reddish-purple lesions appear on the pads of fingers and toes or near the nails of fingers and toes.
Lesions caused by vasculitis may ulcerate or blister if they erupt on mucous membranes in the mouth, nose, or vagina and can be painful if they occur on the throat.
Vasulitis can attack blood vessels in almost any other organ, including the brain, the heart, and the gastrointestinal tract.

Other symptoms include:

Fatigue
Loss of appetite, nausea, and weight loss
Chest pain
Bruising
Menstrual irregularities
Thought and concentration disturbances
Personality changes
Sleep disorders, such as restless legs syndrome and sleep apnea
Dryness of the eyes and mouth
Brittle hair or hair loss

Hair loss or breakage may also occur in about half of patients with SLE during severe flares or after pregnancy or severe illness. In such cases, hair grows back.

Raynaud's phenomenon is a condition in which cold or stress can cause spasms in impaired blood vessels, resulting in pain in fingers and toes. It occurs as part of the inflammatory response in blood vessels, which can narrow them and reduce circulation. In extreme cases, gangrene can result.

Click the icon to see an image of Raynaud's phenomenon.

A number of conditions may resemble SLE:

Scleroderma: Hardening of the skin caused by overproduction of collagen
Multiple sclerosis: Fatigue, heaviness or clumsiness in the arms and legs
Rheumatoid arthritis: Inflammation of the lining of the joints
Sjögren syndrome: Characterized by dry eyes and dry mouth
Mixed connective tissue disorder: Similar to SLE, but milder
Myositis: Inflammation and degeneration of muscle tissues
Rosacea: Flushed face with pus-filled blisters
Seborrheic dermatitis: Sores on lips and nose
Lichen planus: Swollen rash that itches, typically on scalp, arms, legs, or in the mouth
Dermatomyositis: Bluish-red skin eruptions on face and upper body
Lyme disease: Bulls-eye rash, joint inflammation, and flu-like symptoms

Complications

Systemic lupus erythematosus (SLE) is one of the most serious rheumatic diseases. According to a 2002 government study, the annual number of deaths has risen from 879 - 1,406 since 1979. About a third of these deaths occur in people aged 15 - 44 years, mostly women. Such numbers may be underestimates, since SLE can affect so many organs that a cause of death in some people with SLE may not be directly attributed to the condition. A primary cause of death among patients with lupus is atherosclerosis, a disease of the coronary blood vessels resulting from accelerated buildup of plaque.

SLE is unpredictable and varies greatly form one individual to the next. Severity also appears to differ among ethnic groups and countries. In European and North American patients with SLE for example, overall 5-year survival rates are 93 - 95%, while in Asia or Africa they are considerable lower (60 - 70%). Other research indicates that African-American and Hispanic American patients suffer greater organ damage than Caucasian patients. Genetic factors appear to have some influence on specific effects of SLE on organ damage among ethnic groups. However, the poorer outlook among minority groups and in underdeveloped nations is probably due to less access to good health care.

Mild SLE. About 20 - 30% of cases are mild. For many of these patients, the only symptoms may be the skin rashes of discoid lupus erythematosus (DLE) or subacute cutaneous lupus erythematosus (SCLE) with or without joint aches. The number and intensity of symptoms in mild cases often decrease over time, as does the likelihood of major organ involvement. These skin conditions, however, are not absolute insurance against more severe disease, and patients with mild SLE should be tested for organ involvement.

Widespread SLE. Most commonly, SLE is a chronic, life-long disease, alternating between periods of symptom relapse, (called flares), and remission. The disease may begin in any of the various systems of the body and progress unpredictably to others. The following are typical patterns:

Symptom relapses, or flares, occur on the average of two or three times a year.
Between flares, most patients with SLE function at about 90% of normal capacity.

The degree of severity depends on different factors:

Severity of the inflammatory response
Frequency of episodes
The degree of organ or system involvement

Vital organs or systems, such as lungs, kidneys, nervous system, joints skin, and others are affected in 50 - 75% of patients with SLE. Infections followed by kidney failure are the chief causes of death in patients with SLE.

Because of more effective and aggressive treatment, the prognosis for SLE has improved markedly over the past two decades. Long-term progress of the disease is affected greatly by treatment in the initial acute phase of the disease, so a speedy and accurate diagnosis is all-important. The 10-year survival rate with treatment is now 85 - 95%, and many people have a normal life span. SLE that develops later in life is generally less serious than SLE that strikes in childhood.

Almost 85% of patients with SLE experience problems associated with abnormalities in the blood.

Anemia. About half of patients with SLE are anemic. Causes include:

Iron deficiencies resulting from excessive menstruation
Iron deficiencies from gastro-intestinal bleeding caused by some of the treatments
A specific anemia called hemolytic anemia, which destroys red blood cells
Anemia of chronic disease

Hemolytic anemia can occur with very high levels of the anticardiolipin antibody. It can be chronic or develop suddenly and be severely (acute).

Antiphospholipid Syndrome. Between 34 - 42% of patients with SLE have antiphospholipid syndrome (APS). This is a specific set of conditions related to the presence of autoantibodies called lupus anticoagulant and anticardiolipin. These autoantibodies react against fat molecules called phospholipids, and so are called antiphospholipids. Their actions have complex effects that include causing narrowing and abnormalities of blood vessels.

Patients who have APS have a very incidence of blood clots, which most often occur in the deep veins in the legs (32%). Blood clotting, in turn, puts patients at higher risk for stroke (13%) and pulmonary embolism (clots in the lungs) (9%).

This picture shows a red and swollen thigh and leg caused by a blood clot (thrombus) in the deep veins in the groin (iliofemoral veins). Such a clot prevents normal return of blood from the leg to the heart.

About 22% of patients have thrombocytopenia -- a reduction in blood platelets that can cause bleeding.
The effects on blood vessels have also been associated with confusion, headaches, and seizures. Leg ulcers can also develop.
Patients with APS who become pregnant have a high incidence of pregnancy loss, especially in the late term.

Not all patients with APS carry both of the autoantibodies, and they can also wax and wane and so have varying effects. APS also occurs without lupus in about half of patients with the syndrome.

Thrombocytopenia. In thrombocytopenia, antibodies attack blood platelets. In such cases, blood clotting is impaired, which causes bruising and bleeding from the skin, nose, gums, or intestines. (This condition can also occur in APS, but it is not considered to be one of the standard features of the syndrome.)

Neutropenia. Neutropenia is a drop in the number of white blood cells. Patients with SLE often neutropenia, but the condition is usually harmless unless the reductions are so severe that they leave the patient vulnerable to infections.

Acute Lupus Hemophagocyte Syndrome. A rare blood complication of SLE that occurs primarily in Asians is called acute lupus hemophagocytic syndrome. It is generally of short duration and characterized by fever and a sudden drop in blood cells and platelets.

Lymphomas. Patients with SLE and other autoimmune disorders have a greater risk for developing lymph system cancers such as Hodgkin’s disease and non-Hodgkin’s lymphoma (NHL). A 2005 study reported that patients with SLE were over seven times more likely to develop NHL than healthy patients.

Heart disease is a primary cause of death in lupus patients. The immune response in SLE can cause inflammation and other damaging effects that can cause significant injury to the arteries and tissues associated with the circulation and the heart. In addition, SLE treatments (particularly corticosteroids) affect cholesterol, weight, and other factors that can also affect the heart. For decades, experts questioned the extent to which the drugs used to treat SLE contributed to the high rate of atherosclerosis in such patients. Numerous studies now suggest that something about the disease process itself, possibly the chronic inflammation of the blood vessels, probably lies at the root of this dangerous problem. In any event, patients with SLE, have a higher chance for the following conditions, which put them at risk for heart attack or stroke:

Atherosclerosis, or plaque buildup in the arteries
Increased stiffness in the arteries
Unhealthy cholesterol and lipid (fatty molecules) levels
High blood pressure, most likely because of kidney injury and corticosteroid treatments
Congestive heart failure
Pericarditis, an inflammation of the tissue surrounding the heart (occurs in about 30% of patients)
Myocarditis, an inflammation of the heart muscle itself (rare)

Click the icon to see an image of pericarditis.

Abnormalities in the valves of the heart (rare)
Blood clots

The risk for cardiovascular disease, heart attack, and stroke is much higher than average in younger women with SLE. The risks decline as such women age.

SLE affects the lungs in about 60% of patients:

Recurrent inflammation of the membrane lining the lung (pleurisy) is the most common problem.
In some cases, fluid accumulates, a condition called pleural effusion, and can cause stabbing localized pain that worsens when coughing, sneezing, laughing, or taking a deep breath.
Inflammation of the lung itself in SLE is called lupus pneumonitis. It can be caused by infections or by the SLE inflammatory process. Symptoms are the same in both cases: fever, chest pain, labored breathing, and coughing. Rarely, lupus pneumonitis becomes chronic and causes scarring in the lungs, which reduces their ability to deliver oxygen to the blood.
A very serious and also rare condition called pulmonary hypertension occurs when high pressure develops in the vessels supplying blood to the lungs.

Click the icon to see an image of primary pulmonary hypertension.

The kidneys are a crucial battleground in SLE because it is here that the debris left over from the immune attacks is most likely to be deposited. About 50% of patients with SLE exhibit inflammation of the kidneys (called lupus nephritis).This condition occurs in different forms and can vary widely in severity.

Click the icon to see an image of the kidney.

Proliferative nephritis is a serious variant of lupus nephritis. It occurs when the inflammatory process causes widespread damage and scarring in the blood vessels of the kidneys, which filters waste products, water, and salts out of the blood. The condition is associated with high blood pressure and kidney deterioration.
Membranous lupus nephritis is another variant that is often associated with a good outlook. In some cases, however, if the kidney is persistently exposed to high protein levels, the disorder can progress to fatal end-stage kidney (renal) disease.

Serious complications occur eventually in about 30% of patients. If kidney injury develops, it almost always occurs within 10 years of the onset of SLE, rarely after that.

Nearly all patients with SLE report some symptoms relating to problems that occur in the central nervous system (CNS), which includes the spinal cord and the brain. Most of these symptoms are minor and some, such as headache, may be related to depression rather than the disease itself. CNS involvement is more likely to occur in the first year, usually during flare-ups in other organs. Symptoms vary widely and may be indistinguishable from psychiatric or neurologic disorders or from the side effects of some medications used for SLE. Central nervous system symptoms are usually mild, but there is little effective treatment available for them. CNS symptoms get worse as the disease progresses.

The most serious CNS disorder is inflammation of the blood vessels in the brain, which occurs in 10% of patients with SLE. Fever, seizures, psychosis, and even coma can occur. Other CNS side effects include:

Irritability
Emotional disorders (anxiety, depression)
Mild impairment of concentration and memory
Migraine and tension headaches
Problems with the reflex systems, sensation, vision, hearing, and motor control

Infections are a common complication and a major cause of death in all stages of SLE. The immune system is indeed overactive in SLE, but it is also abnormal and reduces the ability to fight infections. Patients are not only prone to the ordinary streptococcal and staphylococcal infections, but they are also susceptible to fungal and parasitic infections (called opportunistic infections), which are common in people with weakened immune systems. They also face an increased risk for herpes, salmonella, and yeast infections. Corticosteroid and immunosuppressants, treatments used for SLE, also increase the risk for infections, thereby compounding the problem.

About 45% of patients with SLE suffer gastrointestinal problems, including nausea, weight loss, mild abdominal pain, and diarrhea. Severe inflammation of the intestinal tract occurs in less than 5% of patients and causes acute cramping, vomiting, diarrhea, and, rarely, intestinal perforation, which can be life-threatening. Fluid retention and swelling can cause intestinal obstruction, which is much less serious but causes the same type of severe pain. Inflammation of the pancreas can be caused by the disease and by corticosteroid therapy.

Arthritis caused by SLE almost never leads to destruction or deformity of joints. The inflammatory process can, however, damage muscles and cause weakness. Patients with SLE also commonly experience reductions in bone mass density (osteoporosis) and have a higher risk for fractures, whether or not they are taking corticosteroids (which can increase the risk for osteoporosis). Women who have SLE should have regular bone mineral density scans to monitor bone health.

Inflamed blood vessels in the eye can reduce blood supply to the retina, resulting in degeneration of nerve cells and a risk of hemorrhage in the retina. The most common symptoms are cotton-wool-like spots on the retina. In about 5% of patients sudden temporary blindness may occur.

In one study, 40% of patients with SLE quit work within 4 years of diagnosis, and many had to modify their work conditions. Significant factors that predicted job loss included high physical demands from the work itself, a more severe condition at the time of diagnosis, and lower educational levels. People with lower income jobs were at particular risk for leaving them.

Women with lupus who conceive face high-risk pregnancies. It is important for women to understand the potential complications and plan accordingly. The most important advice is to avoid becoming pregnant when lupus is active.

Research suggests that the following factors predict a successful pregnancy:

Disease state at time of conception. Experts strongly recommend that women wait to conceive until their disease state has been inactive for at least 6 months.
Kidney (renal) function. Women should make sure that their kidney function is evaluated prior to conception. Poor kidney function can worsen high blood pressure and cause excess protein in the urine. These complications increase the risk for preeclampsia and miscarriage.
Lupus-related antibodies. Antiphospholipid and anticardiolipin antibodies can increase the risks for preeclampsia, miscarriage, and stillbirths. Anti-SSA and anti-SSB antibodies can increase the risk for neonatal lupus erythematosus, a condition that can cause skin rash and liver and heart damage to the newborn baby. Levels of these antibodies should be tested at the start of pregnancy. Certain medications (aspirin, heparin) and tests (fetal heart monitoring) may be needed to ensure a safe pregnancy.
Medication use during pregnancy. Women with active disease may need to take low-dose corticosteroids, but women with inactive disease should avoid these drugs. Steroids appear to pose a low risk for birth defects, but can increase a pregnant woman’s risks for gestational diabetes, high blood pressure, infection, and osteoporosis. For patients who need immunosuppressive therapy, azathioprine (Imuran) is an option. Methotrexate (Rheumatrex) and cyclophosphamide (Cytoxan) should not be taken during pregnancy.

Pregnancy Risks

Women with lupus are 20 times more likely to die during pregnancy than women without the disease. The risk for maternal death is due to the following serious conditions that can develop during pregnancy:

Miscarriages. About 25% of lupus pregnancies result in miscarriage. The risk is highest for patients with antiphospholipid antibodies, active kidney disease, or high blood pressure.
Blood clots. Women with lupus have a 6 times greater risk for developing deep vein thrombosis (blood clots) than women without the disease.
Clotting complications. Low blood platelet count and anemia are also risks. Women with lupus are 3 times more likely to need a transfusion during pregnancy than women without lupus.
Infections. Blood infections (sepsis), pneumonia, and urinary tract infections are more common in pregnant women with lupus.
Preeclampsia. Women with lupus are three times more likely than healthy women to develop preeclampsia (pregnancy-related high blood pressure), which can be potentially life threatening.

Birth Complications

Pre-term birth. Women with lupus are 2.5 times more likely to have pre-term labor than women without lupus. Pre-term labor increases the risk for giving birth to low-weight babies.
Stillbirths. A 2005 study reported that the risk of still births was 10 times greater for women who had not yet been diagnosed with lupus, and 4 times greater for women with diagnosed lupus, compared with healthy women. This suggests that lupus may have a pre-disease state.
Caesarean section. Thirty-seven percent of women with lupus require a C-section compared with 22% of women without the disease.

Despite these obstacles, many women with lupus have healthy pregnancies and deliver healthy babies. To increase the odds of a successful pregnancy, it is important for women to plan carefully before becoming pregnant. Be sure to find knowledgeable doctors with whom you can communicate and trust. Experts recommend that pregnant women with lupus assemble an interdisciplinary health care team that includes a rheumatologist, high-risk obstetrician, and (for patients with kidney disease) a nephrologist.

Diagnosis

No single test can confirm or rule out SLE. A number of tests are required before SLE can be diagnosed definitively. The first symptoms of SLE can resemble one of many syndromes or disorders, including rheumatoid arthritis, Still's disease, rheumatic fever, Lyme disease, multiple sclerosis, thrombotic thrombocytopenia purpura, cryoglobulinemia, Weber-Christian disease, viral infections, vasculitis, psychosis, and other conditions. Other autoimmune disorders, such as Sjögren syndrome or scleroderma, may even be present at the same time as SLE.

1. Characteristic rash across the cheek

2. Discoid lesion rash

3. Photosensitivity

4. Oral ulcers

5. Arthritis

6. Inflammation of membranes in the lungs, the heart, or the abdomen

7. Evidence of kidney disease

8. Evidence of severe neurologic disease

9. Blood disorders, including low red and white blood cell and platelet counts

10. Immunologic abnormalities

11. Positive antinuclear antibody (ANA)

Note: A patient must experienced four of the criteria before a doctor can classify the condition as SLE. These criteria, proposed by the American College of Rheumatology, are not to be relied upon solely for diagnosis, however.

Methods for measuring the antibodies involved with SLE vary, and the range of results can be bewildering. Repeat tests may be needed.

Antinuclear Antibodies (ANAs). A primary test for SLE checks for antinuclear antibodies (ANA), which attack the cell nucleus.

High levels of ANA are found in more than 98% of patients with SLE. A number of other conditions, however, also cause high levels of ANA, so a positive test is not a definite diagnosis for SLE:

Antinuclear antibodies may be strongly present in other autoimmune diseases (such as scleroderma, Sjögren syndrome, or rheumatoid arthritis).
They also may be weakly present in about 20 - 40% of healthy women.
Some drugs can also produce positive antibody tests, including hydralazine, procainamide, isoniazid, and chlorpromazine.

A negative ANA test makes a diagnosis of SLE unlikely but not impossible. High or low concentrations of ANA also do not necessarily indicate the severity of the disease, since antibodies tend to come and go in patients with SLE.

In general, the ANA test is considered a screening test:

If SLE symptoms are present and the ANA test is positive, other tests for SLE will be administered.
If SLE symptoms are not present and the test is positive, the doctor will look for other causes, or the results will be ignored if the patient is feeling healthy.

ANA Subtypes. In some cases, doctors may test for specific ANA subtypes.

Anti-double stranded DNA (Anti-ds DNA) is usually found only in patients with SLE. It may play an important role in injury to blood vessels found in SLE, and high levels often indicate kidney involvement. Anti-ds DNA levels tend to fluctuate over time and may even disappear.
Anti-Sm antibodies are also usually found only with SLE. They are more constant and are more likely to be detected in African-American patients. Although the antibody is not usually seen in lupus patients, its confirmed presence almost always indicates SLE.
When the ANA is negative but the diagnosis is still strongly suspected, a test for anti-Ro (also called anti-SSA) and anti-La (also called anti-SSB) antibodies may identify patients with a rare condition called ANA negative, Ro lupus. These autoantibodies may be involved in the sun-sensitive rashes experienced by patients with SLE and are also found in association with neonatal lupus syndrome, in which a pregnant mother's antibodies cross the placenta and cause inflammation in the developing child's skin or heart.

Antibodies to SR Proteins. An advance in diagnosing SLE has been the detection of antibodies to molecules called SR proteins, which are carried by most patients. The test accurately detects lupus in 50 - 70% of patients who test positive for these antibodies.

Antiphospholipid Antibodies. In patients with SLE in whom blood abnormalities are suspected, tests may be able to detect the presence of the two major antiphospholipid antibodies:

A quarter to a half of patients with SLE may have these antibodies. They attack blood-clotting regulator proteins that stick to phospholipids, fatty compounds found in cell membranes throughout the body. Antiphospholipid antibodies increase the risks for blood clots and may be responsible for narrowing of (and irregularities in) blood vessels. Antiphospholipid antibodies are linked with miscarriages and other pregnancy complications, strokes, heart attacks and blood clots in almost any part of the body, including kidneys, legs, lungs, and eyes.
The test for the lupus anticoagulant antibody measures the time it takes blood to clot. A longer than normal blood clotting time indicates a higher chance for clotting in the body and, therefore, the presence of lupus anticoagulant.
An ELISA test (enzyme-linked immunosorbent assay) is performed to detect the anticardiolipin antibody.

As with the ANA, these antibodies also have a tendency to appear and disappear in a single patient. Patients who have these autoantibodies as well as blood clotting problems or frequent miscarriage are diagnosed with antiphospholipid syndrome (APS), which often occurs in SLE but can also develop independently.

Complement. Blood tests of patients with SLE often show low levels of serum complement, a protein in the blood that aids the body's infection fighters. Individual proteins are termed by the letter "C" followed by a number. Common complement tests measure C3, C4, C1q, and CH50. There is some evidence that complete deficiencies of C1q may be a key factor in the inability of the immune system to contain the autoimmunity process. Complement levels are especially low if there is kidney involvement or other disease activity.

LE Cell Tests. The first blood test ever used for SLE called LE (lupus erythematosus) cell test is positive in only about half of patients with SLE and is no longer used that often.

Blood Count. White and red blood cell and platelet counts are usually lower than normal and, depending on severity, are used to determine complications, such as anemia or infection.

If a skin rash is present, the doctor may take a biopsy (a tissue sample) from the margin of a skin lesion. A test known as a lupus band detects antibodies known as immunoglobulin G (IgG), which are located just below the outer layer of the tissue sample. They are present in about 80% of patients with active SLE and in 30 - 40% of those with inactive disease. The biopsy will not differentiate between systemic and discoid lupus, but it can rule out other diseases. Tests for other antibodies will rule out or confirm discoid lupus and subacute cutaneous lupus.

Kidney Damage and Lupus Nephritis. Kidney damage in patients already diagnosed with SLE may be detected from the following tests:

Blood tests that measure creatinine, a protein metabolized in muscles and excreted in the urine. High levels suggest kidney damage, although it can also be present with normal creative levels.
Tests for detecting anti-ds DNA antibodies and complement. High levels of anti-ds DNA and low levels of complement C3 suggest kidney damage. (It should be noted, however, that some patients with severe kidney damage show low levels of anti-ds DNA.) Testing for anti-C1q antibodies now appears to be an even more reliable indicator of lupus nephritis.
Urine analysis. Urine analyses should be performed at 4- to 6-month intervals to check for signs of kidney involvement.
A kidney biopsy. This may be performed to determine if lupus nephritis is present when less invasive tests indicate kidney involvement. It is not absolutely accurate but it helps determine treatment. Electron microscopy (very high-powered electronic microscopes) may be especially important in obtaining critical information on the degree of kidney damage.

Lung and Heart Involvement. A chest x-ray may be performed to check lung and heart function. An electrocardiogram and an echocardiogram are administered if heart disease is suspected.

Central Nervous System Complications. SLE occurring in the central nervous system (CNS) can be difficult to diagnose because its symptoms are easily confused with other psychiatric and neurologic conditions.

Tests of the cerebrospinal fluid (CSF) for elevated levels of autoantibodies are the most reliable ways to detect CNS complications caused by a faulty immune system.
Additional tests, including electroencephalograms (EEGs), magnetic resonance imaging (MRI), computed tomography (CT), or x-rays may be useful when blood vessel blockage in the brain is suspected.
If the doctor suspects that CNS symptoms are caused by infection, especially for patients who are receiving immunosuppressant therapy, a lumbar puncture should be performed.

Osteoporosis. To detect early osteoporosis in patients with SLE whose disease has lasted more than 3.5 years, experts recommend an imaging test called dual energy x-ray absorptiometry (DEXA) to measure bone mineral density.

Treatment

No treatment cures systemic lupus erythematosus, but many therapies can suppress symptoms and relieve discomfort. Treatment of SLE varies depending on the extent and severity of the disease.

Only three drugs are FDA-approved for the treatment of lupus:

Prednisone
Aspirin
Hydroxychloroquine

However, none of these drugs are the current standard of care. In everyday practice, numerous other drugs are commonly used. Researchers are conducting numerous clinical studies and drug investigations. Genetic research in lupus is progressing very rapidly, and hopefully new drugs will be approved in the future. There are also different drugs available to treat some of the conditions associated with lupus.

Less intensive treatments may be effective for symptoms of mild lupus. They include:

Creams and sunblocks for rashes
Nonsteroidal anti-inflammatory drugs for fever, arthritis, and headache
Antimalarial drugs for pleurisy, mild kidney involvement, and inflammation of the tissue surrounding the heart

More aggressive treatment is needed if there is serious disease progression, as evidenced by:

Hemolytic anemia
Low platelet count with an accompanying rash (thrombocytopenia purpura)
Major involvement in the lungs or heart
Significant kidney damage
Acute inflammation of the small blood vessels in the extremities or gastrointestinal tract
Severe central nervous system symptoms

The primary approach to treating severe SLE is to suppress the immune factors, most often first with corticosteroids and other immunosuppressant drugs. Investigational drugs and procedures are also showing promise.

The major complications of the disease must be treated as separate problems, keeping in mind the specific aspects of SLE. They are discussed elsewhere in this report.

Treatment for Cutaneous and Mild SLE

Creams. Steroid creams are often used for skin lesions. However, many patients with discoid lupus do not respond to steroids, particularly if they have eruptions that are caused by sun sensitivity. A cream derived from vitamin A (Tegison) may help some lesions that do not clear up with steroid creams.

Sun Protection. Sun protection is essential. Patients should always use sunblock creams (not just sunscreens) and always wear hats and clothing made of tightly woven fabrics.

Common NSAIDs. NSAIDs block prostaglandins, the substances that dilate blood vessels and cause inflammation and pain. There are dozens of NSAIDs.

Over-the-counter NSAIDs include aspirin, ibuprofen (Motrin, Advil), naproxen (Aleve), ketoprofen (Actron, Orudis KT).
Prescription NSAIDs include ibuprofen (Motrin), naproxen (Naprosyn, Anaprox), diclofenac (Voltaren), tolmetin (Tolectin), ketoprofen (Orudis, Oruvail), dexibuprofen (Seractil).

For people with lupus, NSAIDs may help relieve:

Joint pain and swelling
Muscle pain

Side Effects. Regular, long-term use of NSAIDs can cause ulcers and gastrointestinal bleeding, which can lead to anemia. To avoid these problems, it’s best to take NSAIDs with food or immediately after a meal. Long-term use of NSAIDs (with the exception of aspirin) can also increase the risk for heart attack and stroke.

Other NSAID side effects may include:

Upset stomach
Dyspepsia (burning, bloated feeling in pit of stomach)
Drowsiness
Skin bruising
High blood pressure
Fluid retention
Headache
Rash
Reduced kidney function

Patients who have kidney problems associated with lupus (lupus nephritis) should be especially cautious about using NSAIDs. Experts recommend that patients with lupus who take NSAIDs on a regular basis should have their liver and kidney function tested every 3 - 4 months.

An ulcer is a crater-like lesion on the skin or mucous membrane caused by an inflammatory, infectious, or malignant condition. Patients can take certain medicines to suppress the acid in the stomach causing the erosion of the stomach lining. Endoscopic therapy can be used to stop bleeding from the ulcer.

Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) is the second most common cause of ulcers. Ulcers caused by nonsteroidal anti-inflammatory drugs (NSAIDs) are more likely to bleed than those caused by the bacteria Helicobacter pylori.

Those at high risk for bleeding include people over age 60, anyone with a history of ulcers or gastrointestinal bleeding, patients with serious heart conditions, people who abuse alcohol, and those who take medications such as anticoagulants (blood thinners) and corticosteroids.

Proton-pump inhibitor (PPI) drugs may help prevent and heal ulcers caused by NSAIDs. PPIs include omeprazole (Prilosec), esomeprazole (Nexium), and lansoprazole (Prevacid).

A doctor may prescribe antimalarial drugs for discoid lupus (skin sores) or mild lupus when skin problems and joint pains are the predominant symptoms:

Hydroxychloroquine (Plaquenil) is the most common antimalarial drug used for lupus. This drug is effective as maintenance therapy to reduce flares in patients with mild or inactive disease. Hydroxychloroquine may help protect against blood clots in people with antiphospholipid syndrome, high cholesterol levels, and bone loss.
Other antimalarial drugs include chloroquine (Aralen) or quinacrine (Atabrine).

Treatment may start initially with high doses in order to accumulate high levels of the drug in the bloodstream. It is not known exactly why antimalarials work. Some researchers believe they inhibit the immune response, and others think they interfere specifically with inflammation.

A 2006 study suggested that anti-malarial drugs work best in patients who have genetic predispositions to certain types of immune-fighting proteins. The study found that patients who had genetic variations causing abnormally high levels of tumor necrosis alpha (TNF-alpha) and abnormally low levels of interleukin-10 (IL-10) responded best to these drugs.

Side Effects. Side effects of antimalarials may include:

Skin rash
Change in skin color (yellow in the case of quinacrine)
Gastrointestinal problems
Headache
Hair loss
Muscle aches
Eye damage

The most serious is damage to the retina, although this is very uncommon at low doses. Eye damage after taking hydroxychloroquine is reversible when caught in time and treated, but it is not reversible if the damage develops after taking chloroquine. An eye exam is advisable about every 6 months.

Antimalarials may also be used in combination with other anti-SLE drugs, including immunosuppressants and corticosteroids. It should be noted that smoking significantly reduces the effectiveness of antimalarial drugs.

Treatment for Severe SLE

Severe SLE is treated with corticosteroids, also called steroids, which suppress the inflammatory process. Steroids can help relieve many of the complications and symptoms, including anemia and kidney involvement.

Oral prednisone (Deltasone, Orasone) is usually prescribed. Other drugs include methylprednisolone (Medrol, Solumedrol), hydrocortisone, and dexamethasone (Decadron).

Some people need to take oral prednisone for only a short time; others may require it for a long duration. An intravenous administration of methylprednisolone using "pulse" therapy for 3 days is proving useful for flare-ups in the joints. Combinations with other drugs, particularly immunosuppressants, may be beneficial.

Regimens vary widely, depending on the severity and location of the disease. Most patients with SLE can eventually function without prednisone, although some may have to choose between the long-term toxicity of corticosteroids and the complications of active disease.

Side Effects of Long-Term Oral Corticosteroids. Unfortunately, serious and even life-threatening complications have been associated with long-term steroid use. The bone-thinning condition osteoporosis is a common and particularly severe long-term side effect of prolonged steroid use. Medications that can prevent osteoporosis include calcium supplements, parathyroid hormone, alendronate etidronate, risedronate, or hormone replacement therapy in post-menopausal women. Vitamin C and E may help reduce the risk of cataracts.

Other side effects associated with prolonged use of oral steroids include:

Cataracts
Glaucoma
Diabetes
Fluid retention
Susceptibility to infections
Weight gain
High blood pressure
Acne
Excess hair growth
Wasting of the muscles
Menstrual irregularities
Irritability
Insomnia
Psychosis

Withdrawal from Long-Term Use of Oral Corticosteroids. Long-term use of oral steroid medications suppresses secretion of natural steroid hormones by the adrenal glands. After withdrawal from these drugs, this so-called adrenal suppression persists and it can take the body a while (sometimes up to a year) to regain its ability to produce natural steroids again. A few cases of severe adrenal insufficiency have occurred when patients switched from oral to inhaled steroids, which, in rare cases, has resulted in death.

No one should stop taking any steroids without consulting a doctor first, and if steroids are withdrawn, regular follow-up monitoring is necessary. Patients should discuss with their doctors measures for preventing adrenal insufficiency during withdrawal, particularly during stressful times, when the risk increases.

Drugs known as immunosuppressants are often used, either alone or with corticosteroids for very active SLE, particularly when kidney or neurologic involvement or acute blood vessel inflammation is present. These drugs suppress the immune system by damaging cells that grow rapidly, including those that produce antibodies. About a third of patients take immunosuppressants at some point in the course of the disease.

Specific Immunosuppressants. The most common immunosuppressants are:

Cyclophosphamide (Cytoxan) used to be considered the gold standard of treatment for lupus kidney disease (lupus nephritis). Cyclophosphamide is given intravenously and is sometimes used in combination with corticosteroids or other drugs. It has been used for lupus since the 1970s. Side effects are very severe and include nausea, vomiting, hair loss, infertility, and infections.
Mycophenolate mofetil (CellCept) is now becoming the new standard. Many recent studies have shown that CellCept works better than cyclophosphamide and causes far fewer severe side effects (diarrhea is the main side effect). Unlike cyclophosphamide, it is taken by mouth. Most doctors now recommend CellCept as a first-line treatment for newly diagnosed patients with mild or moderate lupus kidney disease. It may not be appropriate for patients with kidney failure or rapidly progressing kidney disease.
Azathioprine (Imuran) has the lowest toxicity, but is less effective than other immunosuppressants.
Cyclosporine (Sandimmune) has been used for years, mostly for SLE associated with kidney involvement. High blood pressure is common, however, with this drug.

The most frequent side effects of immunosuppressants include:

Stomach and intestinal problems
Skin rash
Mouth sores
Hair loss

Serious side effects of immunosuppressants include:

Low blood cell counts
Anemia
Menstrual irregularity
Early menopause
Ovarian failure
Infertility
Herpes zoster (shingles)
Liver and bladder toxicity
Increased risk of cancer

In general, immunosuppressants should not be used alone unless corticosteroids are ineffective or inappropriate. Grapefruit juice has an enzyme that may enhance the effects of some immunosuppressants.

Monoclonal Antibodies (MAbs). A MAb is a laboratory-made protein that targets specific immune cells, such as B cells. B cell over-activation has been identified as a key component of the lupus disease process. Promising MAbs in development for SLE treatment include:

Epratuzumab is being investigated for treatment of moderate-to-severe lupus. It is currently in Phase III trials.
Belimumab (Lymphostat-B) is also in Phase III trials.
Rituximab (Rituxan), a lymphoma cancer and rheumatoid arthritis drug, has shown good results in early trials in improving lupus symptoms. Researchers think it may affect how T cells and B cells interact. However, in December 2006 the FDA warned of several cases of progressive multifocal leukoencephalopathy (PML) in patients with lupus who took this drug. PML is a life-threatening brain infection. Some patients developed PML as late as 12 months after their last dose of rituximab. Two patients with lupus died from PML.

Intravenous Immunoglobulins. Intravenous immunoglobulins (IVIG) are sometimes used for patients who have not responded to other SLE treatments. Immunoglobulins are antibodies produced by immune system B-lymphocyte cells. IVIG is a blood product that contains these antibodies.

Dehydroepiandrosterone (DHEA). Dehydroepiandrosterone (DHEA) is a natural steroid hormone that is produced by the adrenal glands and converted into estrogen and androgen. The synthetic equivalent of DHEA, prasterone (Prestara), is being investigated as a potential treatment for SLE. Several clinical trials have indicated promising, although mixed, results for prasterone’s effect on preventing bone mineral density loss in women who take prednisone. Prasterone is still in the drug development stage and it is not clear when, or if, it will be commercially available.

Autologous Stem Cell Transplantation. Some patients with severe lupus have achieved at least short-term remission after undergoing autologous transplantation of stem cells and high-dose drug therapy to suppress the damaging immune factors. Stem cells are the early forms for all blood cells in the body. An autologous transplant is one in which marrow or blood cells used are the patient's own. (The advantage to an autologous transplant is that the patient's own cells are not at risk for rejection by the immune system.)

The procedure first removes the cells from the patient, who then receives high-dose immunotherapy. The stem cells are then reintroduced. Early results of small studies are encouraging, especially for treatment of antiphospholipid syndrome. Evidence suggests that these re-introduced stem cells do not repeat the original autoimmune errors. A 2006 study in the Journal of the American Medical Association indicated that autologous stem cell transplantation can help boost the immune system and lead to remission. Patients in the study had severe lupus that was resistant to standard treatments. Results were long-lasting. Researchers calculated that patients had a 50% chance of remaining disease-free after 5 years.

UVA-1 Phototherapy. A promising treatment uses ultraviolet A-1 (UVA-1) radiation, long UVA wave lengths that do not promote sunburn and may actually block inflammatory immune factors. Small studies have suggested that UVA-1 phototherapy may have some benefits for lowering disease activity in SLE.

Plasmapheresis. Plasmapheresis is a process in which the fluid part of the blood, called plasma, is removed from blood cells. The procedure involves first taking blood from the patient. The plasma, which contains the inflammatory antibodies and other immunologically active substances, is discarded and replaced with other fluids. The blood is then returned. Plasmapheresis is not useful for routine management of patients but may have some benefits for patients who do not respond to standard treatments or in specific cases, such as lupus patients with hemolytic anemia.


Infections, Inflammation, or Hypertension in the Lungs	Preventive Measures. Immunizations with inactive viruses and preventive antibiotics should be considered for patients with SLE who are at high risk for infection. Treating Infections. Lung infections need to be treated aggressively with antibiotics. However, antibiotic drugs such as penicillin or the sulfa drugs may cause sensitivity rashes that can be confused with SLE rash. Treating Lung Inflammation. While inflammation of the lung (pneumonitis) resembles pneumonia, it is not an infection but is a result of the autoimmune process. This condition needs to be treated with corticosteroids or immunosuppressants, but only if the doctor is sure infection is not present. Treating Pulmonary Hypertension. Pulmonary hypertension is very serious. Drugs known as prostacylins -- which include epoprostenol, iloprost, and treprostinil -- are standard drugs. Bosentan (Tracleer) is the first oral drug approved for pulmonary hypertension. An inhaled iloprost formulation (Ventavis) was approved in 2004. Sildenafil (Viagra, Revatio) may also be used for this condition. Lung transplantation may be required.
Bleeding and Clotting Disorders	Antiphospholipid Syndrome and Clotting Disorders. Hydroxychloroquine or aspirin may help prevent blood clots in women with antiphospholipid syndrome (APS). (Aspirin does not appear to be protective in men who carry the autoantibodies responsible for APS.) In patients who have experienced blood clots, treatment with the anticoagulant warfarin (Coumadin) is advisable. This blood-thinning drug may be needed lifelong. Scientists are investigating other treatment options, including autologous stem cell transplantation. The procedure has shown promise in studies for treating lupus-associated APS, but it is still experimental. Excess Bleeding from Thrombocytopenia (Drop in Blood Platelets). Treatments that may be effective for thrombocytopenia include combinations of a corticosteroid and either danazol (a male hormone) or the antimalarial hydroxychloroquine. Immunosuppressants or intravenous immunoglobulin IgG may be helpful in some patients. Surgical removal of the spleen may be advisable if bleeding disorders are a serious problem, but this option should be considered carefully, because the spleen provides one line of defense against infection. (Abnormal spleen function, in any case, appears to be fairly common in SLE.)
Kidney Disease	Drugs. Mycophenolate mofetil (CellCept), a newer drug, can help treat kidney disease associated with SLE and has fewer side effects than other immunosuppressants. It is taken by mouth. Recent studies suggest that it works better than cyclophosphamide. CellCept may be best for patients with mild-to-moderate lupus kidney disease and may not be appropriate for patients with advanced kidney disease. Intravenous cyclophosphamide is the most effective drug at this time for proliferative lupus nephritis, and, in combination with a steroid, has been shown to control advanced kidney disease in 60 - 90% of patients. It has severe side effects, including nausea, vomiting, hair loss, and infertility. Steroids are also useful for treating active kidney disease and for managing milder forms of nephritis. Procedures. Kidney transplant or dialysis should be considered for patients with SLE with severe kidney damage. For unknown reasons, SLE does not generally recur in the transplanted kidneys. Studies are conflicting, however, over whether SLE transplant patients have higher organ-rejection rates than other kidney-transplant recipients. Both transplantation and dialysis have potentially serious complications. Plasmapheresis. It is not clear if plasmapheresis is beneficial for SLE kidney disease.
Osteoporosis	Treatments for osteoporosis include calcium, vitamin D, bisphosphonates, parathyroid hormone, and selective estrogen-receptor modulators (SERMs). [For more information, see In-Depth Report #18: Osteoporosis.]
Heart Disease	The need for aggressive treatment of high blood pressure often accompanies kidney disease. SLE is also accompanied by high cholesterol levels, which requires diet changes and drug therapies. [For more information, see In-Depth Reports #3: Coronary artery disease; #14: High blood pressure; #23: Cholesterol; and #43: Heart healthy diet.]

The spleen is an organ that helps produce and maintain red blood cells. It also aids the body's immune system by producing white blood cells that destroy harmful substances in the body. Removal of the spleen makes a person more susceptible to infection.

Lifestyle Changes

People with SLE should try to maintain a healthy and active lifestyle. Light-to-moderate exercise, interspersed with rest periods, is good for the heart, helps fight depression and fatigue, and can help keep joints flexible.

Patients should minimize their exposure to crowds or people with contagious illnesses. Careful hygiene, including dental hygiene, is also important.

It is very important that patients with SLE avoid excessive exposure to sunlight. Simple preventive measures include avoiding overexposure to ultraviolet rays and wearing protective clothing and sunblocks. There is some concern that allergy shots may cause flare ups in certain cases. Patients who may benefit from them should discuss risks and benefits with an SLE specialist. In general, patients with SLE should use only hypoallergenic cosmetics or hair products.

Chronic stress has profound physical effects and influences the progression of SLE. Getting adequate rest of at least 8 hours and possibly napping during the day may be helpful. Maintaining social relationships and healthy activities may also help prevent the depression and anxiety associated with the disease.

Why Didn't Anybody Tell Me: Short Shirts

babysugar — Fri, 29 Aug 2008 08:00:03 -0700

One of the perks of maternity clothes, especially shirts, is that they actually cover your belly. When my belly got too big to hide, I stowed my tops away for future seasons. As the postnatal months passed by, I eagerly waited to pull on my forgotten threads. Down 10 pounds from my pre-pregnancy body weight, I was leaner and more confident that my old wardrobe would be ready for wear.

My jeans fit fine, if not a tad loose, and my bras definitely had room to spare. The shirts, on the other hand, were a tad too short! I never sported a midriff and I rarely wore tight clothes so why, oh why, were my tees rising so high? Had my torso lengthened during my pregnancy, or did my shirts magically shrink in their plastic bins? Perplexed by this issue and bummed to be donating such fab tops, I consulted my mommy friends. They declared the same thing - their pre-pregnancy shirts seemed shorter without reasonable explanation.

Did you experience the shirt-shortening phenomenon?

How Would YOU Wear It? Garcelle Beauvais

FabSugar — Thu, 27 Sep 2007 07:00:22 -0700

I don't normally like to cap on pregnant women because I can only imagine how hard it is to find stylish and flattering maternity wear. But allow me to go there with actress Garcelle Beauvais because this is one of the least flattering maternity ensembles I've seen in a while.

Let's start with the dress. I love the emerald jewel tone but the silk fabric makes her look super shiny and draws too much attention to her midsection. The tie-neck is also really distracting. If I were Garcelle, I would have worn a sleeveless dress to show off those slender arms and to take the attention off her tummy. I would have kept the gold clutch as it's chic and the tights as they're slimming. Those shoes are a bit confusing but they're the least of her worries.

How would YOU wear it?
