Cool Idea: Julene Harrison's Papercut Artwork

CasaSugar — Wed, 05 Aug 2009 11:00:32 -0700

I've completely fallen in love with British artist Julene Harrison's papercut artwork - which you may recognize from my Love Your City? Say It With Art slideshow. From one sheet of paper, she cuts these ornate frames with stunning typography and intricate imagery inside them. Many have romantic messages like, "I Carry Your Heart I Carry It in My Heart" or "I Want to Hold Your Hand," and even "Will You Marry Me?" She's also created more eccentric papercuts like the one that reads "I Have to Return Some Videotapes," and been commissioned by a Finnish ad agency. Each is more charming than the next - so much that I was inspired to re-create a San Francisco-themed papercut like this one for a couple of friends who are moving away. To see it,read more.

I did a little Photoshopping to change the text to "You Will Be Missed," added in an airplane and a glass of wine, and replaced Coit Tower with a frame for a photo of my pals. I've made some papercuts before from paint swatches, but using thin white printer paper was much easier. Since I've been using X-acto knives for years for all of my decoupage crafts, I was comfortable cutting . . . but I can't compete with Harrison's talent for design!

Would you like one for yourself or a loved one? You can have Julene make a custom papercut for you with whatever words and imagery you like!

How-To: Marimekko Your Whole House

CasaSugar — Thu, 11 Jun 2009 10:00:41 -0700

Finnish textile designer Marimekko was made famous when Jackie Kennedy bought eight Marimekko dresses, which she wore throughout the 1960 US presidential campaign. Soon, in the mid-'60s, the company sparked up a relationship with Crate & Barrel, using their designs on textiles like bedding in their stores as well as display backdrops.
Nowadays, Mari's brightly colored graphics have made their way onto every furnishing in the house - a new line of wallpaper being the latest.

Bemz, the one and only retailer of chic slipcovers for Ikea furniture, also recently debuted a collection of Marimekko slipcovers. And, for those of you who have caught on to the trend of using apparel as home décor, the company also launched Mari's New Bags last month, a line of cheerful purses, clutches, and briefcases.

That's not all though, folks: there are plenty more accessories and furnishings for your whole house from the Helsinki company. To see them, read more.

This Just In: Tom Dixon Makes Foray Into Fashion

CasaSugar — Thu, 04 Sep 2008 05:30:07 -0700

British industrial designer and head of design at Finnish company Artek Tom Dixon, who has been designing furniture for 30-some years, and whose lighting designs are all the rage, has decided to channel his design talents into the world of fashion. A new bimonthly fashion digest magazine, Distill, targeted towards creative professionals, launched on Monday, and Dixon is on the editorial board for the next issue, according to Design Week. The new glossy is published by Craft Publishing. Along with Dixon, the editorial board will be composed of fashion designer Giles Deacon, Design Museum director Dejan Sudjic, fashion designer Matthew Williamson, and Net-a-Porter founder Natalie Massenet. The first issue showcases the work of about 25 global fashion and style magazines.

For details, read more.

While this new read may be up Fab’s alley, I am certainly curious about it as well, as it seems to be a departure for furnishing-focused Dixon. Distill creative and publishing director Lockwood explains that the new publication “is about the way fashion is presented globally.” “Fashion is an important visual stimulus and inspiration to the creative sector as a whole, which is why we have recruited designers from a range of disciplines to sit on the editorial board,” he explains. There’s certainly an overlap in trends where fashion and interiors are concerned, especially in textiles, so it’ll be interesting to see what’s in store for this new pub.

New Product Alert: Marimekko for Avon

BellaSugar — Thu, 25 Sep 2008 07:00:49 -0700

I love beautifully designed makeup (witness Lancôme's elephant-adorned bronzer, for example). But you know what I don't love? After using the item once or twice, the colors blend together and the perfect design is over. In the grand scheme of things, it's not a big deal - but why shell out big bucks just for the design?

That is why I am excited about these Marimekko for Avon palettes, which feature the Finnish textile brand's iconic Unikko print. At $8 for the eye shadow palette and $10 for an all-over face palette, they won't make you too depressed when the design begins to look less crisp. Cute and cheap? CasaSugar will be thrilled.

Colds and the flu

FitSugar — Wed, 08 Oct 2008 17:35:26 -0700

HEALTH GUIDE REFERENCE FROM A.D.A.M

Highlights

Vaccine News:

On September 28, 2007, the U.S. Food and Drug Administration (FDA) approved a new brand of inactivated influenza ("flu") vaccine, Alfuria, for adults aged 18 years or older. This vaccine is given by injection.
On September 19, 2007, the FDA approved the use of the live flu vaccine (FluMist) in healthy children as young as 2 years of age. This vaccine, given in the form of a nose spray, was previously approved for healthy children and non-pregnant adults aged 5 - 49.

Drug Resistance:

The World Health Organization reports that resistance to the anti-viral drug oseltamivir (Tamiflu) can develop with extensive use. Oseltamivir is one of two drugs the CDC recommends for treating the flu. It is also the current recommended treatment for the H5N1 avian flu virus.

Drug Recalls:

In October 2007, drug manufacturers voluntarily withdrew from the market all oral cough and cold products, including decongestants, aimed at children under 2, due to potential harm from misuse. The U.S. Food and Drug Administration (FDA) recommends against using these products to treat children under age 2. The FDA is currently reviewing the safety of cough and cold medicines in children ages 2 - 11 years.

Emerging Virus:

A new, more virulent strain of adenovirus has reportedly emerged in the United States in 2006. The adenovirus family causes upper respiratory infections, pneumonia, and several other diseases. The new strain of adenovirus 14 causes severe respiratory illness that has resulted in several deaths.

Introduction

Upper respiratory tract infections affect the airways in the nose, ears, and throat.

Structures of the throat include the esophagus, trachea, epiglottis, and tonsils.

The infections can be caused by viruses, bacteria, or other microscopic organisms. In most cases, these infections lead to colds or mild influenza (flu) and are temporary and harmless. In rare cases, flu can be severe, or the infections may turn into pneumonia.

Organisms that cause these upper respiratory tract infections are generally spread by:

Direct contact (such as hand-to-mouth)
Coughing or sneezing

The common cold (medically known as infectious nasopharyngitis) is the most common upper respiratory tract infection. More than 200 viruses can cause colds. The most common cause is the rhinovirus, which is responsible for about half of all colds. Symptoms usually develop 1 - 3 days after being exposed to the virus.

A cold usually progresses in the following manner:

It nearly always starts rapidly with throat irritation and stuffiness in the nose.
Within hours, full-blown cold symptoms usually develop, which can include sneezing, mild sore throat, fever, minor headaches, muscle aches, and coughing.
Fever is low-grade or absent. In small children, however, fever may be as high as 103°F for 1 or 2 days. The fever should go down after that time, and be back to normal by the 5th day.
Nasal discharge is usually clear and runny the first 1 - 3 days. It then thickens and becomes yellow to greenish.
The sore throat is usually mild and lasts only about a day. A runny nose usually lasts 2 - 7 days, although coughing and nasal discharge can persist for more than 2 weeks.

A new, more virulent strain of adenovirus has reportedly emerged in the United States in 2006. The adenovirus family causes upper respiratory infections (it is one of the many viruses that cause the common cold). It also causes pneumonia, conjunctivitis, and several other diseases. The new strain of adenovirus 14 causes severe respiratory illness that has resulted in several deaths. Some patients who contracted this new viral disease had to be hospitalized, sometimes in intensive care units.

Every year, influenza strikes millions of people worldwide. Influenza epidemics are most serious when they involve a new strain, against which most people around the world are not immune. Such global epidemics (pandemics) can rapidly infect more than one fourth of the world's population. For example, the Spanish flu in 1918 and 1919 killed an estimated 20 million people in the U.S. and Europe and 17 million people in India. With modern society's dependence on air travel, an influenza pandemic could potentially inflict catastrophic damage on human lives, and disrupt the global economy.

The influenza virus mutates (changes) rapidly as it moves from species to species. Most Type A influenza strains (the most common strains) first develop in migratory waterfowl populations. While most avian influenza (bird flu) virus strains are relatively harmless, a few develop into "highly pathogenic avian influenza," which can be very deadly for domesticated poultry and livestock. As recent events have shown, these strains can also be deadly to humans. People can become infected by these bird flu strains through contact with contaminated chickens and pigs. The medical community is now greatly concerned about the H5N1 bird flu virus, which has infected and even killed people in several countries.

Symptoms of influenza. Patients usually feel sick 1 - 4 days after exposure to the influenza (flu) virus. The flu usually involves:

Abrupt onset of severe symptoms, which include headache, muscle aches, fatigue, and high fever (up to 104°F).
Cough (which is usually dry but can be severe) and sometimes a runny nose and sore throat.
Children may experience vomiting, diarrhea, and ear infections, as well as other flu symptoms.
The symptoms usually resolve in 4 - 5 days, although some people can experience coughing and feelings of illness for more than 2 weeks. In some cases, flu can become more severe or make other conditions worse.

Transmitting the Virus. The flu virus is spread primarily when a person with the flu coughs or sneezes near someone else. Adults with flu typically spread it to someone else from 1 day before symptoms start to about 5 days after symptoms develop. Children can spread the infection for more than 10 days after symptoms begin, and young children can transmit the virus 6 days or even earlier before the onset of symptoms. People with severely compromised immune systems can transmit the virus for weeks or months.

Flu Strains. A virus is a cluster of genes wrapped in a protein membrane, which is coated with a fatty substance that contains molecules called glycoproteins. Strains of the flu are identified according to the number of membranes and type of glycoproteins present.

Click the icon to see an image of a virus.

The two major flu strains are referred to as A and B:

Influenza A is the most widespread and can infect animals and humans. Influenza A is the cause of the major pandemics (worldwide epidemics) of influenza that have occurred so far. It is usually further categorized by two subtypes based on two substances that occur on the surface of the viruses: hemagglutinin (H) and neuraminidase (N).
Influenza B infects only humans. It is less common than type A, but is often associated with specific outbreaks, such as in nursing homes.

The vast majority of flu cases are type A. Influenza A usually causes more severe disease than type B. There is some concern, however, that since influenza B has been less common in the past few years, some people, particularly small children, may have fewer antibodies to it and so may be at higher risk for severe infection.

Although the risk of lethal viruses is generally low, scientists are greatly concerned about a particular virus called H5N1, which causes avian influenza. Since 1997, the H5N1 virus has triggered deadly outbreaks in poultry across Southeast Asia. As of Janaury 15, 2008, 350 people had been infected with the bird flu in 12 countries. Of these people, 217 have died, according to the World Health Organization. No cases have been seen in the United States.

So far, the virus has spread from birds to humans. The virus does not seem to be easily spread from person to person. However, scientists and public health officials are monitoring the spread of H5N1 and working to contain it. Efforts include slaughtering infected birds, developing new vaccines, and stockpiling antiviral drugs such as oseltamivir (Tamiflu). Many poor nations have limited resources and already contend with other serious health problems, including HIV-AIDS. If H5N1 does mutate and spread, the consequences could be especially severe for these countries.

In April 2007, the FDA approved a vaccine to protect humans from avian influenza. Currently this vaccine is not being used for routine immunization. However, if the avian flu develops the ability to spread fairly easily from human to human, this vaccine may be made available.

Diagnosis

Differentiating between a cold and flu may be difficult. Cold symptoms are nearly always less severe than those of the flu.


Symptoms	Cold	Flu
Fever	Rare	Common and high (102-104°F); lasts 3 - 4 days
Headache	Rare	Almost always present
General aches and pains	Mild, if they occur at all	Often severe
Fatigue, exhaustion, and weakness	Mild, it they occur at all	Extreme exhaustion is early and severe; can last 2 - 3 weeks
Stuffy nose	Nearly always	Sometimes
Sneezing	Very common	Sometimes
Sore throat	Common	Sometimes
Chest discomfort and cough	Mild-to-moderate, hacking cough	Common, can be severe
Source: National Institute of Allergy and Infectious Disease

Several available tests can isolate and identify the viruses responsible for some respiratory infections. They are generally not needed, since most cases of the flu are self-evident. However, such tests can be very helpful in confirming or ruling out the flu. If a doctor believes a diagnosis would help, samples using a swab should be taken from the nasal passages or throat within 4 days of the first symptoms.

A nasopharyngeal culture is a test used to identify disease-causing organisms in nasal secretions. Nasopharyngeal cultures are useful in identifying Bordetella pertussis and Neisseria meningitidis (types of bacteria). The culture may help determine appropriate antibiotic therapy.

Several rapid tests for the flu can produce results in less than 30 minutes, but vary on the specific strain or strains that they can detect. They are not as accurate as a viral culture, however, in which the virus is reproduced in the laboratory. Culture results can take 3 - 10 days. Blood tests can also document the infection several weeks after symptoms appear.

In February 2006, the U.S. Food and Drug Administration approved a new, faster test for diagnosing H5 strains of avian influenza in people suspected of having the virus. The test is called the Influenza A/H5 (Asian lineage) Virus Real-time RT-PCR Primer and Probe Set. The test gives preliminary results within 4 hours. Older tests required 2 - 3 days. It checks for the presence of the Influenza A H5 strain. If the presence of this strain is confirmed through the rapid test, further testing will be needed to determine the exact subtype of the virus. For example, the current strain of concern is H5, subtype N1, designated as H5N1 for short.

Ruling out Allergic Rhinitis. Symptoms of allergic rhinitis include nasal obstruction and congestion, which are similar to the symptoms of a cold. People with allergies, however, are likely to have the following:

Thin, clear, and runny nasal discharge
An itchy nose, eyes, or throat
Recurrent sneezing

There are two forms of allergic rhinitis:

Symptoms that appear only during allergy season are called allergic rhinitis, commonly known as hay or rose fever. [For more information, see In-Depth Report #77: Allergic rhinitis.]
Allergens in the house, such as house dust mites, molds, and pet dander, can cause year-long allergic rhinitis, referred to as perennial rhinitis.

Click the icon to see an image of common allergens.

Ruling out Sinusitis. The signs and symptoms suggestive of true acute sinusitis include the following:

A return of congestion and discomfort after initial improvement in a cold (called double sickening)
Purulent (pus-filled) nasal secretion
A lack of response to decongestant or antihistamine
Pain in the upper teeth or pain on one side of the head
Pain above or below both eyes when leaning over

Children with sinusitis are less likely to have facial pain and headache and may only develop a high fever or prolonged upper respiratory symptoms (such as a daytime cough that does not improve for 11 - 14 days). When the diagnosis is unclear or complications are suspected, further tests may be required. [For more information, see In-Depth Report #62: Sinusitis.]

Acute Bronchitis. Acute bronchitis is usually caused by a virus and in most cases is self-limiting. The cough it causes typically lasts for about 7 - 10 days, but in about half of patients, coughing can last for up to 3 weeks, and 25% of patients continue to cough for over 1 month.

Atypical Pneumonia. Pneumonia caused by atypical organisms (for example, Mycoplasma pneumonia, chlamydia, Legionella) can cause symptoms similar to the flu. Only laboratory tests can diagnose the difference. [For more information, see In-Depth Report #64: Pneumonia.]

Ruling out More Serious Viral Infections. Respiratory syncytial virus (RSV) and, possibly human parainfluenza viruses (HPV), are proving to be important causes of serious respiratory infections in infants, the elderly, and people with damaged immune systems. (Both also cause mild conditions.) RSV may be a much more common cause of flu-like symptoms than previously thought.

Pertussis. Pertussis (whooping cough) was a very common childhood illness throughout the first half of the century. Although immunizations caused a decline in cases to only 1,700 in the U.S. in 1980, the incidence has risen recently, with almost 30,000 cases reported between 1997 and 2000 (17 infants died of the disease in 2000). Many more cases are reported worldwide.

Nearly half of pertussis cases now occur in people 10 years of age or older, perhaps due to waning immunity in adolescents and adults. Such cases may be greatly underreported. Up to 25% of adults who see a doctor for persistent cough may actually have pertussis. It may go undiagnosed, however, because symptoms are usually mild, and adults are unlikely to have the classic "whooping" cough. This is of some concern because such adults may unknowingly infect unvaccinated children. The younger the patient, the higher the risk for severe complications, including pneumonia, seizures, and even death. Children younger than 6 months are at particular risk because protection is incomplete, even with vaccination.

In addition to common cold viruses, other, less frequent causes of sore throat include the following:

Strep throat
Foodborne and waterborne infections (Streptococcus C and G)
An uncommon organism called Arcanobacterium haemolyticum (infection with this bacterium can mimic strep throat and may even cause a rash)
Infectious mononucleosis ("mono")
Herpesvirus 1

Group A Streptococcal bacteria is the most common bacterial cause of the severe sore throat known commonly as "strep throat." It occurs mostly in school age children, but people of all ages are susceptible. (Strep throat constitutes about 12% of all sore throat cases seen by doctors.)

The symptoms of strep throat include the following:

A sudden onset of severe sore throat
Difficulty in swallowing
Fever
Headache
Stomach pain
Vomiting

Only about half of patients with strep throat have such clear-cut symptoms. Furthermore, half of people who have these symptoms do not actually have strep throat.

How Is Strep Throat Diagnosed? Most cold-related sore throats are caused by viruses and require no treatment. They usually do not last more than a day. When the sore throat persists and is very painful the doctor will want to rule out or confirm the presence of the strep bacteria.

The doctor will look for redness and pus-filled patches on the tonsils and back of the throat. Enlarged tonsils are less likely to indicate a strep throat.
The doctor will feel the sides of the neck for swollen lymph nodes. If the lymph nodes are not swollen, it is less likely to be a strep throat.
A cotton swab is used to take a sample of pus in the throat for a throat culture.

A throat culture is the most effective and least expensive test for confirming the presence of strep throat. It takes 24 - 48 hours to obtain a result.

Rapid Antigen-Detection Test for Strep Throat. A faster test, called the rapid strep antigen test, uses chemicals to detect the presence of bacteria in a few minutes. A positive result nearly always means that streptococcal bacteria is the cause of the infection. The test, however, fails to detect 10 - 20% of cases, so a culture may still be necessary to catch any missed infections, particularly in children.

How Serious is Strep Throat? The use of antibiotics has removed the threat of most complications from streptococcus infection in the throat (strep throat). However, untreated strep throat could lead to the following complications:

Abscess in the tonsils
Scarlet fever
Rheumatic fever (rare in the U.S.)

How Is Strep Throat Treated? Strep throat infections require antibiotics. Antibiotics prevent a serious complication called rheumatic fever, which can result in permanent damage to the heart. Fortunately, this complication occurs rarely in United States anymore. If started on time, antibiotic treatment of strep throat will almost always prevent this complication. In addition, antibiotics shorten the recovery time from strep throat.

The following antibiotics are generally used to treat strep throat:

Penicillin is usually the antibiotic of choice unless the patient is allergic. A full 10 days may be necessary. Amoxicillin, a form of penicillin, is proving to be effective when taken in a single daily dose for 10 days.
Macrolide antibiotics. Erythromycin is known as a macrolide antibiotic and is the first choice for patients with penicillin allergies. A 10-day regimen is needed. Another macrolide, azithromycin, can be given as a single daily dose and may be effective in 5 days. It is expensive, however, and bacterial resistance to macrolides is growing, so it should not be given as a first choice.
Cephalosporins are very effective in eradicating the bacteria.

Antibiotics are very commonly inappropriately prescribed for non-strep sore throats. One study reported that an estimated 6.7 million American adults visited their doctors because of sore throat between 1989 and 1999, with 73% of them receiving antibiotics. Studies indicate, however, that fewer than half of adults and far fewer children with even strong signs and symptoms for strep throat actually have strep infections.

Parents should be comforted that a delay in antibiotic treatment while waiting for lab results does not increase the risk that the child will develop serious long-term complications, including acute rheumatic fever. If a patient is severely ill, however, it is reasonable to begin administering antibiotics before the results are back. If the culture is negative (there is no evidence of bacteria), the doctor should call the family to make certain the patient stops taking the antibiotics and any remaining pills are discarded.

Children who have a sore throat and who have had rheumatic fever in the past should receive antibiotics immediately, even before culture results are back. Children with a sore throat who have a family member with strep throat or rheumatic fever should also receive immediate antibiotic treatment.

Complications

Colds rarely cause serious complications. In about 1% of cases, a cold can lead to other complications, such as sinus or ear infections. It can also aggravate asthma and, in uncommon situations, increase the risk for lower respiratory tract infections.

Ear Infections. The rhinovirus infection, a major cause of colds, also commonly predisposes children to ear infections, possibly by obstructing the Eustachian tube, which leads to the middle ear. Viruses may even attack the ear directly.

Sinusitis. Between 0.5 - 5% of people with colds develop sinusitis, an infection in the sinus cavities (air-filled spaces in the skull). Sinusitis is usually mild, but if it becomes severe, antibiotics generally eliminate further problems. In rare cases, however, sinusitis can be serious.

Lower Respiratory Tract Infections. The common cold poses a risk for bronchitis and pneumonia in nursing home patients, and in other people who may be vulnerable to infection. Some experts believe that the rhinovirus may play a more significant role than the flu in causing lower respiratory infections in the vulnerable population.

Aggravation of Asthma. Rhinovirus infections can aggravate asthma in both children and adults. In fact, rhinovirus has been reported to be the most common infectious organism associated with asthma attacks. Colds may promote allergic inflammation of the airways, and increase the intensity their responsiveness for weeks.

The flu is usually self-limited and not serious. However, each year in the United States, more than 200,000 people are hospitalized due to complications of the flu. An estimated 36,000 people die each year of influenza-related complications. People at highest risk for serious complications are those over 65 years old and those with chronic medical conditions. Influenza A is the most severe strain. Influenza B tends to be milder.

Pneumonia. Pneumonia is the major serious complication of influenza and can be very serious. It can develop about 5 days after viral influenza. More than 90% of the deaths caused by influenza and pneumonia occur among older adults. Flu-related pneumonia nearly always occurs in high-risk individuals, such as the following:

People with weakened immune systems, such as AIDS patients
Elderly patients, particularly patients in nursing home
Very young children -- [it may be difficult to tell whether pneumonia is related to influenza or caused by respiratory syncytial virus (RSV)]
Hospitalized patients and anyone with serious medical conditions, such as diabetes, heart, circulation, or lung disorders, particularly chronic lung disease
Drug abusers who use needles

Combinations of these factors further increase the risk. It should be noted that pneumonia is an uncommon outcome of influenza in healthy adults.

Complications in the Central Nervous System in Children. Influenza increases the risk for complications in the central nervous system of small children. Febrile seizures are the most common neurologic complication in children The risks decline after a child turns 1 year old, but are still high in children aged 3 - 5 years old.

Risk Factors

The very young and the very old are at higher risk for upper respiratory tract infections and their associated complications.

Children. Young children are prone to colds and may have 8 to 12 of them every year. Millions of cases of influenza develop in American children and adolescents each year.

Before the immune system matures, all infants are susceptible to uppper respiratory infections, with a possible frequency of one cold every 1 - 2 months. Smaller nasal and sinus passages also make younger children more vulnerable to colds than older children and adults. Upper respiratory infections gradually diminish as children grow, until at school age their rate of such infections is about the same as an adult's. There is almost never cause for concern when a child has frequent colds, unless the colds become unusually severe or more frequent than usual.

The Elderly. The elderly have diminished cough and gag reflexes, and their immune systems are often weaker. They are therefore at greater risk for serious respiratory infections than the young and middle-aged adults.

The risk of respiratory infections is increased by exposure to cigarette smoke, which can injure airways and damage the cilia (tiny hair-like structures that help keep the airways clear). Toxic fumes, industrial smoke, and other air pollutants are also risk factors. Parental smoking increases the risk of respiratory infections in their children.

People with AIDS and other medical conditions that damage the immune system are extremely susceptible to serious infections.

Cancers, especially leukemia and Hodgkin's disease, put patients at risk. Patients who are on corticosteroid (steroid) treatments, chemotherapy, or other medications that suppress the immune system are also prone to infection.

People with diabetes are at a higher risk for the flu.

Certain genetic disorders predispose people to respiratory infections. They include sickle-cell disease, cystic fibrosis, and Kartagener syndrome (which results in malfunctioning cilia).

Much evidence suggests that stress increases one's susceptibility to a cold. In one study, people with high stress levels averaged 2.7 upper respiratory infections during a 6-month period and those reporting low stress averaged 1.5 infections. Another study found the duration of colds in children with chronic, year-round colds decreased with help of a stress management program. Stress appears to increase the risk for a cold regardless of lifestyle or other health habits. And once a person catches a cold or flu, stress can make symptoms worse.

It is not clear why these events occur. Some experts believe that stress alters specific immune factors, which cause inflammation in the airways. One study reported that the only people who got sick after experiencing short stress were those whose body responded to stress with high levels of cortisol, a stress hormone, coupled with a low immune response.

In people who already have colds, exercise has no effect on the illness' severity or duration of the infection. High-intensity or endurance exercises, however, appear to suppress the immune system while they are being performed. Some highly trained athletes, for instance, report being susceptible to colds after strenuous events. People should avoid strenuous physical activity when they have high fevers or widespread viral illnesses. Note: Very low fat diets appear to worsen this dampening effect on the immune system. A higher fat-diet may help correct this imbalance (omega-3 fatty acids, found in fish and canola oil, are preferred). Whether carbohydrate loading provides much additional value is not clear.

Colds and flus occur predominantly in the winter. Flu season typically starts in October and lasts into mid March.

The reasons for this seasonal bias are not due to the cold itself, but to other factors. Certainly, flus and colds are more likely to be transmitted in winter because people spend more time indoors and are exposed to higher concentrations of airborne viruses. Dry winter weather also dries up nasal passages, making them more susceptible to viruses. Some experts theorize that the high rates of viral infections in winter may be due to certain immune factors, which react to light and dark and affect a person's susceptibility to viruses.

Traveling in close contact with people, whether on trains, planes, or buses, can increase the risk for respiratory infections.

Children who attend day care may have an increased risk of colds. However, one study suggested that although children in day care centers incur higher rates of the common cold in the preschool years, they have lower cold rates in their first years of regular school. The colds they catch in day care, then, may bestow some immunity to future colds for a few years. By age 13, such protection has worn off. There is also some evidence that frequent colds in young children may help protect against future allergies and asthma.

Prevention

Because colds and flus are easily spread, everyone should always wash their hands before eating and after going outside. Ordinary soap is sufficient. Waterless hand cleaners that contain an alcohol-based gel are also effective for every day use and may even kill cold viruses. (They are less effective, however, if extreme hygiene is required. In such cases, alcohol-based rinses are needed.)

Antibacterial soaps add little protection, particularly against viruses. In fact, one study suggests that common liquid dish washing soaps are up to 100 times more effective than antibacterial soaps in killing respiratory syncytial virus (RSV), which is known to cause pneumonia. Wiping surfaces with a solution that contains one part bleach to 10 parts water is very effective in killing viruses.

Colds are not caused by insufficiently warm clothes or by going outside with wet hair.

Foods Containing Lactobacilli (Good Bacteria). Researchers are also studying the possible protective value of certain strains of lactobacilli bacteria found in the intestines. Some of these strains, particularly acidophilus, are used to make yogurt. According to one Finnish study, children attending day care who ate milk containing the strain lactobacilli GG 10 - 20% fewer respiratory infections. (The strain used was not the kind found in most commercial yogurt products.)

Vitamins. Studies are mixed whether vitamin supplements protect against upper respiratory infections. Large doses of vitamin C, for example, may help reduce the duration of a cold, but they do not appear to protect against one in the first place, even after exposure to a cold virus. Two studies on multivitamins reported opposite results, with one finding fewer infections and one finding no difference. It is possible that vitamin C or multivitamin supplements may be helpful in specific people, such those who are vitamin deficient or have medical problems that impair their immune systems.

Treatment

The following are some food and fluid recommendations. Most will not cure a cold, but they may help a person deal better with the symptoms:

Drinking plenty of fluids and getting lots of rest when needed is still the best bit of advice to ease the discomforts of the common cold. Water is the best fluid and helps lubricate the mucous membranes. (There is no evidence that drinking milk will increase or worsen mucus, although milk is a food and should not serve as fluid replacement.)
Chicken soup does indeed help congestion and body aches. The hot steam from the soup may be its chief advantage, although laboratory studies have actually reported that ingredients in the soup may have anti-inflammatory effects. In fact, any hot beverage may have similar soothing effects from steam. Ginger tea, fruit juice, and hot tea with honey and lemon may all be helpful.
Spicy foods that contain hot peppers or horseradish may help clear sinuses.
Foods rich in vitamins A and C are always recommended and may be helpful during a respiratory infection. They include oranges, kiwi, and tomatoes for vitamin C, and sweet potatoes, spinach, and broccoli for vitamin A.

Different studies have found that large doses of vitamin C may reduce the duration of a cold. Some precautions against taking high doses of vitamin C include the following:

High doses of vitamin C may cause headaches, intestinal and urinary problems, and even kidney stones.
Because vitamin C increases iron absorption, people with certain blood disorders, such as hemochromatosis, thalassemia, or sideroblastic anemia, should avoid high doses of this vitamin.
Large doses of vitamin C can also interfere with anticoagulant medications ("blood thinners"), blood tests used in diabetes, and stool tests.
Vitamin E or multivitamin supplements do not appear to be helpful in reducing symptoms of the cold.

Zinc appears to have certain important effects on the immune system and it may have a direct effect on viruses. How it works is not entirely clear, however. Zinc preparations in lozenge or nasal gel form are now available as cold treatments. Studies are very mixed on the effects of zinc on colds. The variance may be due to different zinc preparations. A review of available studies comparing zinc treatment to placebo ("sugar pill") found only one high-quality study, which showed that zinc nasal gels might provide a benefit. The overall benefit of zinc in the prevention of colds remains unproven. In any case, no one with an adequate diet and a healthy immune system should take zinc for prolonged periods, for the purpose of preventing colds.

Side Effects. Side effects, particularly of the lozenges form, include the following:

Dry mouth
Constipation
Nausea
Bad taste (possibly only with zinc gluconate lozenges)
Severe vomiting, dehydration, and restlessness (signs of overdose, seek medical help)
Allergic response (rare)

Food and Drug Interactions. Zinc may also interact with drugs or other elements:

It may reduce absorption of certain antibiotics.
Foods high in calcium or phosphorus may reduce zinc absorption.
In high doses and for long periods of time, zinc can cause copper deficiencies.

Many people take medications to reduce mild pain and fever. Adults most often choose aspirin, ibuprofen (Advil), or acetaminophen (Tylenol).

The following are recommendations for children:

Acetaminophen (Tylenol) or ibuprofen (usually Advil or Motrin) are the typical pain-relievers parents give their children. Most pediatricians advise such medications for children who run fevers over 101°F. Some suggest alternating the two agents, although there is no evidence that this regimen offers any benefits, and it might be harmful.
Aspirin and aspirin-containing products are virtually never recommended for children or adolescents. Reye syndrome, a very serious condition, has been associated with aspirin use in children who have flu symptoms or chicken pox.

Nasal strips (such as Breathe Right) are placed across the lower part of the nose and pull the nostrils open. These strips may open the nasal passages and ease congestion due to a cold, sinusitis, or hay fever. As of yet, there is no scientific evidence that they offer such benefits.

A nasal wash can be helpful for removing mucus from the nose. A saline solution can be purchased at a drug store or made at home. One study reported that neither a homemade solution (using one teaspoon of salt and one pinch of baking soda in a pint of warm water) nor a commercial hypertonic saline nasal wash had any effect on symptoms. Further, one preliminary study found that over-the-counter saline nasal sprays that contain benzalkonium chloride as a preservative may actually worsen symptoms and infection.

Some physicians, however, advocate a traditional nasal wash that has been used for centuries and is different from that used in most studies. It contains no baking soda and uses more fluid for each dose and less salt. The nasal wash should be performed several times a day.

A simple method for administering a nasal wash:

Lean over the sink head down.
Pour some solution into the palm of the hand and inhale it through the nose, one nostril at a time.
Spit the remaining solution out.
Gently blow the nose.

The solution may also be inserted into the nose using a large rubber ear syringe, available at a pharmacy. In this case, the process is the following:

Lean over the sink head down.
Insert only the tip of the syringe into one nostril.
Gently squeeze the bulb several times to wash the nasal passage.
Then press the bulb firmly enough so that the solution passes into the mouth.
The process should be repeated in the other nostril.

Nasal-delivery decongestants are applied directly into the nasal passages with a spray, gel, drops, or vapors. Nasal forms work faster than oral decongestants and have fewer side effects. They often require frequent administration, although long-acting forms are now available. Ingredients and brands of nasal decongestants include the following:

Long Acting Nasal-Delivery Decongestants. They are effective in a few minutes and remain so for 6 - 12 hours. The primary ingredient in long-acting decongestant is:

Oxymetazoline: Brands include Vicks Sinex (12-hour brands), Afrin (12-hour brands), Dristan 12-Hour, Good Sense, Nostrilla, Neo-Synephrine 12-Hour
Xylometazoline: Inspire, Otrivin, Natru-vent

Short-Acting Nasal-Delivery Decongestants. The effects usually last about 4 hours. The primary ingredients in short-acing decongestants are:

Phenylephrine: Neo-Synephrine (mild, regular, high-potency), 4-Way, Dristan Mist Spray, Vicks Sinex
Naphazoline (Naphcon Forte, Privine)

Dependency and Rebound. The major hazard with nasal-delivery decongestants, particularly long-acting forms, is a cycle of dependency and rebound effects. The 12-hour brands pose a particular risk for this effect. This effect works in the following way:

With prolonged use (more than 3 - 5 days), nasal decongestants lose effectiveness and even cause swelling in the nasal passages.
The patient then increases the frequency of their dose. The congestion worsens, and the patient responds with even more frequent doses, in some cases as often as every hour.
Individuals then become dependent on them.

Tips for Use. The following precautions are important for people taking nasal decongestants:

When using a nasal spray, spray each nostril once. Wait a minute to allow absorption into the mucosal tissues, and then spray again.
Keep the nasal passages moist. All forms of nasal decongestants can cause irritation and stinging. They also may dry out the affected areas and damage tissues.
Do not share droppers and inhalators with other people.
Use decongestants only for conditions requiring short-term use, such as before air travel or for a single-allergy attack. Do not take them more than 3 days in a row. With prolonged use, nasal decongestants become ineffective and result in the so-called rebound effect and dependence.
Discard sprayers, inhalators, or other decongestant delivery devices when the medication is no longer needed. Over time, these devices can become reservoirs for bacteria.
Discard the medicine if it becomes cloudy or unclear.

Oral decongestants also come in many brands, which mainly differ in their ingredients. The most common active ingredient is pseudoephedrine (Sudafed, Actifed, Drixoral).

Side Effects of Decongestants. Decongestants have certain adverse effects, which are more apt to occur in oral than nasal decongestants and include the following:

Agitation and nervousness
Drowsiness (particularly with oral decongestants and in combination with alcohol)
Changes in heart rate and blood pressure

Avoid combinations of oral decongestants with alcohol or certain drugs, including monoamine oxidase inhibitors (MAOI) and sedatives

Individuals at Risk for Complications from Decongestants. People who may be at higher risk for complications are those with certain medical conditions, including disorders that make blood vessels highly susceptible to contraction. Such conditions include the following:

Heart disease
High blood pressure
Thyroid disease
Diabetes
Prostate problems that cause urinary difficulties
Migraines
Raynaud's phenomenon
High sensitivity to cold
Emphysema or chronic bronchitis

Anyone with the above conditions should not use either oral or nasal decongestants without a doctor's guidance. In addition, people taking medications that increase serotonin levels, such as certain antidepressants, anti-migraine agents, diet pills, St. John's wort, and methamphetamine, should avoid decongestants. The combinations can cause blood vessels in the brain to narrow suddenly, causing severe headaches and even stroke.

Others who should use these drugs with caution are the following (consult your health care provider):

Anyone who is pregnant.
Children: Children appear to metabolize decongestants differently than adults. Decongestants should not be used at all in infants and small children under the age of 2, according to a new recommendation from an advisory panel of the Food and Drug Administration. These children are at particular risk for side effects that depress the central nervous system. Such symptoms cause changes in blood pressure, drowsiness, deep sleep, and, rarely, coma. Studies have also shown that these cough and cold products generally are not effective in the treatment of children under 6 years of age.

In October 2007, drug manufacturers voluntarily withdrew from the market all oral cough and cold products, including decongestants, aimed at children under 2, due to potential harm from misuse.

Major studies have indicated that over-the-counter cough medicines are not very effective, but they are also not harmful.

For thick phlegm, patients may try cough medications that contain guaifenesin (Robitussin, Scot-Tussin Expectorant), which loosens mucus. Patients should not suppress coughs that produce mucus and phlegm. It is important to expel this substance. To loosen phlegm, patients should drink plenty of fluids and use a humidifier or steamer.
For patients with a dry cough, a suppressant may be useful, such as one that contains dextromethorphan (Drixoral Cough, Robitussin Maximum Strength Cough Suppressant).

Medications that contain both a cough suppressant and an expectorant are not useful and should be avoided. Medicated cough drops that contain dextromethorphan are not very useful. A patient is just as likely to find relief from hard candy or lozenges.

Prescription cough medications with small doses of narcotics are available. They are usually reserved for lower respiratory infections with significant coughs.

Sore throats that are associated with colds are generally mild. The following may be helpful:

Cough drops, throat sprays, or gargling warm salt water may help relieve sore throat and reduce coughing.
Throat sprays that contain phenol (for example, Vicks Chloraseptic) may be particularly helpful. Phenol has antibacterial properties. In one study, patients with sore throat who used the spray experienced faster resolution of the cold itself, including fever, headache, and other symptoms compared to a placebo. The patients were not taking antibiotics.
Cough drops that contain menthol and mild anesthetics, such as benzocaine, hexylrescorincol, phenol, and dyclonine (the most potent), may soothe a mild sore throat.
People with sore throats from postnasal drip might try taking a teaspoon of liquid antacid. They shouldn't drink anything afterward, since the intention is to coat the throat and help neutralize the acid in the mucus that might be causing pain.

If soreness in the throat is very severe and does not respond to mild treatments, the patient or parent should check with the physician to see if a strep throat is present, which would require antibiotics. [See What is Strep Throat? in the Diagnosis section.]

Dozens of remedies are available that combine ingredients aimed at more than one cold or flu symptom. In general, they do no harm, but they have the following problems:

Some ingredients may produce side effects without even helping a cold.
In some cases, the ingredients conflict (such as a cough expectorant and a cough suppressant).
In other cases, a patient may wish to increase the dosage to improve one symptom, which serves to increase other ingredients that do no good and, in higher doses, may cause side effects.

Note on Antihistamines. Many combination remedies contain antihistamines. Antihistamines are used for allergies and are not generally recommended to relieve the symptoms of the common cold. Some evidence suggests, however, that they may have some value.

First-generation antihistamines may reduce cold symptoms. Their benefits for the cold are likely to be due to the drowsiness they cause. Such antihistamines include Benadryl, Tavist, and Chlor-Trimeton. The newer, second-generation antihistamines (Claritin, Allegra, Zyrtec) do not have these effects and also appear to have no benefits against colds.

Herbal remedies and dietary supplements are not regulated by the FDA. This means that manufacturers and distributors do not need FDA approval to sell their products. In addition, any substance that affects the body's chemistry can, like any drug, produce side effects that may be harmful. There have been numerous reported cases of serious and even deadly side effects from herbal products.

The following are special concerns for people taking natural remedies for colds or influenza:

Echinacea is commonly taken to prevent onset and ease symptoms of cold or flu. A rigorous study, published in 2005 in the New England Journal of Medicine, determined that this herb does not help to prevent or treat colds. In addition, some people are allergic to echinacea. People who have autoimmune diseases or plant allergies should avoid it. There have been a few reports of people experiencing a skin reaction called erythema nodosum, which is characterized by tender, red nodules under the skin.
Chinese herbal cold and allergy products can contain trace amounts of aristolochic acid, a chemical that causes kidney damage and cancer. Many herbal remedies imported from Asia may contain potent pharmaceuticals, such as phenacetin and steroids, as well as toxic metals.

Medications

Vaccines are available to prevent influenza (See section on Viral Influenza Vaccines).

For mild influenza, symptom relief is similar to that for colds.

Two classes of antiviral agents have been developed to treat influenza: neuraminidase inhibitors and M2 inhibitors.

Brands and Benefits. Zanamivir (Relenza) and oseltamivir (Tamiflu) are neuraminidase inhibitors. They are newer agents that have been designed to block a key viral enzyme, neuraminidase, which is involved with viral replication. According to a major review of over 50 studies published in 2006, these drugs are effective against the flu in about 60% of cases.

Important points about the use of these drugs:

Neuraminidase inhibitors are effective for treating both A and B strains of influenza. (M2 inhibitors are effective only against type A.) However, their main benefit has been to reduce the length of symptoms by about one day, and only when started within 48 hours after symptoms become evident.
They may help reduce transmission of the virus.
They have a lower risk than M2 inhibitors for emerging viral strains that are resistant to their effects. However, The World Health Organization reports that viral resistance to oseltamivir (Tamiflu) can develop with extensive use. The level of resistance averaged 0.3% over 3 flu seasons surveyed in Japan (2003 - 2006). During that time, 35 million Japanese patients used the drug.
They have fewer serious side effects than the M2 inhibitors.
Both show some benefits for preventing influenza. Only oseltamivir has been approved for this purpose, however, and only in people over 13.
They may reduce complications of influenza, although this needs to be confirmed. It is not yet known if they have any effect on overall survival rates.
Oseltamivir is the only drug studied in avian flu cases. Although it is active in lab experiments, it has not been successful clinically. Experience is very limited, however, and it is not clear whether people infected with avian flu received the drug in time for it to be useful.

Limitations and Side Effects. Although they have many advantages compared to the M2 inhibitors, neuraminidase inhibitors are much more expensive. They also need to be taken within 2 days of the start of symptoms to be effective. Neither neuraminidase inhibitor is effective against influenza-like illness (one that is not caused by an influenza virus). There are also some differences between the two drugs that could be significant for some individuals:

Zanamivir is administered as a nasal spray or inhaler. People with asthma or other lung disorders may experience airway spasms and should use this drug with caution. Side effects are generally minor in most patients. It is important to make sure that elderly patients are able to properly use the zanamivir inhaler device.
Oseltamivir comes in capsule and liquid form. Side effects are also minor, but about 10 - 15% of patients experience nausea and vomiting. Patients with kidney dysfunction should take lower doses.

The current use of neuraminidase inhibitors in different age and patient groups is as follows:

Adults: Both drugs are approved for treatment in adult patients.
Children: Oseltamivir is approved for use in children age one and older. Studies report significant reduction in symptoms and in the incidence of ear infections in this population. However, studies from Japan point to the possibility of psychiatric side effects in children under 16 using oseltamivir. Zanamivir is approved for children over age 7, and studies are currently underway to determine its safety in younger children.
High-Risk Patients. Recent studies indicate neuraminidase inhibitors are safe and effective in patients with serious medical problems or other conditions that put them at risk for complications of flu.

Brands and Benefits. Amantadine (Symmetrel) and rimantadine (Flumadine) are M2 inhibitors. The following benefits may apply to the minority of strains of influenza A that remain sensitive to the drugs:

Both offer protection against influenza A and prevent severe illness if a person contracts the infection. (To be effective it must be administered within 2 days of onset.)
They may shorten the duration and lessen the severity of the flu if given within 48 hours of onset of symptoms.

Limitations. Drawbacks of M2 inhibitors include:

Viral resistance to these agents is rapidly emerging. For this reason, the Centers for Disease Control and Prevention Does not recommends M2 inhibitors for use during the 2007 - 2008 flu season in the United States.
M2 inhibitors are not effective against influenza B.
Neither drug has proven to reduce the risk for complications of the flu, including pneumonia and bronchitis.

Side Effects. Both M2 inhibitors occasionally cause nausea, vomiting, indigestion, insomnia, and hallucinations. Amantadine affects the nervous system and about 10% of people experience nervousness, depression, anxiety, difficulty concentrating, and lightheadedness. Rimantadine is less likely to do so. Rarely, amantadine can cause seizures, usually in elderly people already at risk for psychiatric symptoms.

Note: Amantadine is a standard treatment for Parkinson's disease and should be continued for that condition.

Flu Shots. These vaccines use inactivated (not live) viruses. They are designed to provoke the immune system to attack antigens contained on the surface of the virus. (Antigens are foreign molecules that the immune system specifically recognizes as alien and targets for attack.)

Unfortunately, the antigens in these influenza viruses undergo genetic changes (called antigenic drift) over time, so they are likely to become resistant to a vaccine that worked in the previous year. Vaccines are then redesigned annually to match the current strain.

Influenza A. The influenza A virus is further categorized by primary molecular antigens (hemagglutinin and neuraminidase), which serve as the targets for the vaccines. Influenza A is a particular problem, because it can infect other species, such as pigs or chicken, and undergo major genetic changes.
Influenza B viruses tend to be more stable than influenza A viruses, but they too vary. Although influenza B has been far less common than A, a vaccine for type B is important because experts are concerned that small children will not have developed any immunity to the virus, and will experience severe flu if they are exposed to type B viruses.

Intranasal (inside the nose) vaccine. A live but weakened intranasal vaccine (FluMist) is proving to be effective and safe in healthy, non-pregnant people aged 2 - 49 years and has been approved by the FDA. It is known as a live, attenuated, intranasal influenza vaccine (LAIV). The vaccine is engineered to grow only in the cooler temperatures of the nasal passages, not in the warmer lungs and lower airways. It boosts the specific immune factors in the mucous membranes of the nose that fight off the actual viral infections. FluMist is given using a nasal spray.

Timing and Effectiveness of the Vaccine. Ideally, people should be vaccinated every October or November. However, it may take longer for a full supply of the vaccine to reach certain locations. In such cases, the high-risk groups should be served first.

Antibodies to the influenza virus usually develop within 2 weeks of vaccination, and immunity peaks within 4 - 6 weeks, then gradually wanes.

Because children under age 8 do not develop strong immune responses to one dose, the CDC recommends two vaccinations given 1 month apart on the first year they receive the vaccine. If children under 8 received only 1 dose of the vaccine on their first immunization year, they should receive 2 doses the following year. Children under 8 who have received single doses for 3 or more years should continue to receive single doses.
It should be noted that if an individual develops influenza symptoms and is accurately diagnosed in time, vaccination of the other members of the household within 36 - 48 hours affords effective protection to those individuals.

In healthy adults, immunization typically reduces the chance of illness by about 70 - 90%. The current flu vaccines may be slightly less effective in certain patients, such as the elderly and those with certain chronic diseases. Even in people with a weaker response, however, the vaccine is usually protective against serious flu complications, particularly pneumonia. In fact, among the elderly, interesting studies are now suggesting that influenza vaccination may help protect against stroke, adverse heart events, and death from all causes.

Children Who Should Be Vaccinated. The following children over 6 months should be vaccinated against influenza:

The American Academy of Pediatrics (AAP) and the CDC recommend influenza vaccination in all healthy children between 6 and 59 months old.
In addition, any child over the age of 2 years with a condition that requires regular medical care or who has been hospitalized for a serious illness (particularly lung or kidney disease, diabetes, sickle-cell, or immune deficiencies). If parents are concerned about vaccines that contain the mercury preservative thimerosal, they can ask their doctor about reduced-thimerosal flu vaccine.
Children who come in direct contact with a person vulnerable to complications from influenza should also be vaccinated.
Children who are receiving long-term aspirin therapy should also be immunized against the flu because they are at higher risk for Reye syndrome, a life-threatening disease, if they get the flu.
Some experts now advocate flu shots for all school-age children. Emerging research indicates that children are responsible for transmitting the vast majority of cases of seasonal flu, and that routine vaccination of school-age children would considerably reduce transmission rates throughout communities.

Older Children and Adults Who Should Be Vaccinated. The following, in order of priority, are the population groups who should be vaccinated each year. The first two groups have the highest need for influenza vaccinations and are given top priority:

All adults 50 years and older. Vaccinated older adults have lower hospitalization rates than unvaccinated peers. Evidence now suggests that vaccination may help protect against adverse heart events (including those after heart surgeries), stroke, and death from all causes in the elderly. Still, studies suggest that only two thirds of the people in this group are vaccinated, mostly because of unwarranted fears of ineffectiveness or adverse effects.
People of any age at high risk for serious complications from influenza. Such people include those with heart disease, lung problems, immune deficiencies, diabetes, kidney disease, or chronic blood disease. Those with any condition that may compromise respiratory function or the handling of respiratory secretions, including people with cognitive dysfunction, spinal cord injuries, seizure disorders, or other neuromuscular disorders, are included in this group. (There have been concerns about the safety of the vaccinations in certain high-risk patients such as those with HIV or asthma. Studies now suggest that the vaccine is generally safe in these patient groups. Furthermore, their risk for serious complications from influenza outweighs any potential adverse effects from the vaccines.)
All health care workers should be vaccinated, according to the ACIP's recommendations.
Household members in contact with individuals who are at high-risk for complications from influenza should be vaccinated.

Other adults who should consider influenza vaccinations include:

People at risk for complications for influenza and who are traveling to the tropics at any time or to the Southern Hemisphere between April and September.
Pregnant women who are at risk for complications of influenza, and who will be in their second or third trimester during flu season. (Vaccinations should usually be given after the first trimester. Exceptions may be women who are in their first trimester during flu season and their risk from complications of the flu is higher than any theoretical risk to the baby from the vaccine.)
Police officers, firefighters, and other public safety officials.

Negative Effects. Possible negative responses to the vaccines include:

Allergic Reaction. Newer vaccines contain very little egg protein, but an allergic reaction still may occur in people with strong allergies to eggs.
Soreness at the Injection Site. Up to two thirds of people who receive the influenza vaccine develop redness or soreness at the injection site for 1 - 2 days afterward.
Flu-like Symptoms. Some people actually experience flu-like symptoms, called oculo-respiratory syndrome, which include cough, wheezing, tightness in the chest, sore throat, or a combination. Such symptoms tend to occur 2 - 24 hours after the vaccination and generally last up to 2 days. These symptoms are not influenza itself but an immune response to the virus proteins in the vaccine. (Anyone with a fever at the time the vaccination is scheduled, however, should wait to be immunized until the ailment has subsided.)
Guillain-Barre Syndrome. Although iIsolated cases of a paralytic illness known as Guillain-Barre syndrome occurred in about one of every 100,000 people vaccinated with the swine-flu vaccine in 1976, it has not been a problem with subsequent vaccines.
There has been some question concerning influenza vaccinations because of some reports that vaccines may worsen asthma. Recent and major studies have been reporting, however, that the vaccination is safe for children with asthma. It is also very important for these patients to reduce their risk for respiratory diseases.

The FDA approved the first vaccine for humans against H5NI influenza virus in April 2007. The vaccine, which is made from a human strain of the virus, could be used in people ages 18 - 64 to prevent the spread of the virus from human to human. The vaccine requires two shots, given about a month apart. It will not be sold commercially, but instead is being purchased by the U.S. government to be stockpiled and distributed to public health officials in the event of an outbreak of avian flu.

In a study, 103 healthy adults received two g shots of the virus, 28 days apart. An additional group of 300 adults received the vaccine at a lower dose, while 48 people received placebo injections. The study showed that 45% of those who received the higher dose developed antibodies that may reduce their risk of getting the avian flu. The most common side effects reported were pain at the injection site, headache, and muscle pain. Research on the vaccine is continuing.

The intense and widespread use of antibiotics is leading to a serious global problem of antibiotic resistance. The inappropriate use of powerful newer antibiotics for conditions such as colds or sore throats poses a particular risk for resistant strains of bacteria. For example, the number of cases of methicillin-resistant Staphylococcus aureus (MRSA) is increasing in people who have no known risk factors. (MRSA causes sometimes-fatal skin infections.) In 2006, rates of Neisseria gonorrhoeae resistance to the fluoroquinolone antibiotics family exceeded 10%. The CDC no longer recommends treating gonorrhea infections with fluoroquinolone first.

When Antibiotics Are Needed for Upper Respiratory Infections.

Antibiotics do not affect viruses and, in healthy individuals, these drugs are almost never necessary or helpful for influenza or colds, even with persistent cough and thick, green mucus. In one disturbing study, antibiotics were prescribed for nearly half of children who went to the doctor for a common cold.

Antibiotics may be required for upper respiratory tract infections only under certain situations, such as the following:

Patients, particularly small children or elderly people, who have medical conditions that put them at high risk for complications from any respiratory tract infections, should usually be given antibiotics.
Patients with severe sinusitis that does not clear up within 7 days (some experts say 10 days) and whose symptoms include one or more of the following: green and thick nasal discharge, facial pain, or tooth pain or tenderness.
Some children with middle ear infections, although experts differ on who will benefit. Some experts recommend that only children under the age of 2 years should be treated with antibiotics, and children over 2 should be treated on a case-by-case basis.
Patients with strep throat or severe sore throat that involves fever, swollen lymph nodes, and absence of cough. (Strep throat makes up only 10 - 15% of all sore throat cases.)
Patients who have an acute cough that is caused by pneumonia (but in few other cases, regardless of the duration of the cough). Experts estimate that, outside the hospital setting, less than 20% of prescriptions for persistent coughing are necessary.

Patients at Highest Risk for Infection with Resistant Bacteria Strains. Some patients are at greater risk for developing an infection resistant to common antibiotics. At this time, the average person is not endangered by this problem. Risk factors include:

Very old or very young age
Exposure to patients with drug-resistant infection
Hospitalization in intensive care
History of an invasive surgical procedure
Staying in the hospital
Prolonged course of antibiotics, particularly within the past 4 - 6 weeks
Serious wounds
Tubes down the throat, catheters, or intravenous (I.V.) lines
Immunosuppression

Children at higher risk for antibiotic resistance are those who attend day care, who are exposed to cigarette smoke, who were bottle-fed, and who had siblings with recurrent ear infections.

What the Health Care Community Is Doing. Prescribing antibiotics only when necessary is the most important step in restoring bacterial strains that are susceptible to antibiotics. Encouraging studies are reporting that inappropriate antibiotic prescriptions are on the decline. Prescriptions for other common respiratory infections, such as otitis media, sore throat, acute bronchitis, and colds and flus have been decreasing.

What Patients and Parents Can Do. Patients and parents can also help with the following tips:

Use home or over-the-counter remedies to relieve symptoms of mild upper respiratory tract infections.
Realize that antibiotics will not shorten the course of a viral infection. It is important for patients and parents to understand that although antibiotics may bring a sense of security, they provide no significant benefit for a person with viral infection, and overuse can contribute to the growing problem of resistant bacteria.
Don't pressure a doctor into prescribing an antibiotic if it is clearly inappropriate. The doctor very often will give in.
If a child needs an antibiotic, ask the doctor whether it is appropriate to use high-dose short-term antibiotics, which may lower the risk for developing resistant strains.
If an antibiotic is prescribed, take the full course, even if you feel better before finishing it.

HEALTH GUIDE REFERENCE FROM A.D.A.M

Overview

Calcium is the most abundant mineral in the body. It is essential for the development and maintenance of strong bones and teeth, the location of about 99% of the body's calcium. Calcium also helps the heart, nerves, muscles, and other body systems work properly. It is probably best known for its effects in preventing osteoporosis. Your body needs several other nutrients in order for calcium to be absorbed and used properly, including magnesium, phosphorous, and especially vitamins D and K.

The best way to get calcium is through food (see Dietary Sources). But although many foods are fortified with calcium, some people may still need to take calcium supplements. In fact, according to the National Institutes of Health, many Americans consume less than half the amount of calcium recommended to build and maintain healthy bones. It is especially important to get enough calcium as you age. Postmenopausal women, people who consume large amounts of caffeine, alcohol, or soda, and those who take corticosteroid medications may need calcium supplements. Calcium deficiency can be found in people with malabsorption problems, such as Crohn's disease, celiac disease, and surgical intestinal resection.

Getting enough calcium can help prevent or treat the following conditions:

Osteoporosis

Calcium is necessary to help build and maintain healthy bones and strong teeth. Studies have shown that calcium, particularly in combination with vitamin D, can help prevent bone loss associated with menopause, as well as the bone loss experienced by older men. If you do not get enough calcium in your diet, taking a supplement may be necessary.

Hypoparathyroidism

People with this condition have underactive parathyroid glands, which are four small glands that sit on the four corners of the thyroid in the neck and produce a hormone that regulates calcium, phosphorous, and vitamin D levels in the body. People with this condition should follow a high-calcium, low-phosphorous diet as prescribed by their doctor. Most often, they will also need to take calcium supplements.

Premenstrual Syndrome (PMS)

One large, well-designed study showed that women who took 1,200 mg of calcium per day reduced their symptoms of PMS by 50%, including headache, moodiness, food cravings, and bloating. A smaller study suggested that calcium may help reduce menstrual pain.

High Blood Pressure

People who do not get enough calcium may be at higher risk for hypertension, and there is some mixed evidence that suggests increasing calcium levels may lower blood pressure slightly. However, not all studies have found that benefit; and researchers aren’t sure whether calcium supplements would have any benefit, or whether it’s the effects of a diet that includes low-fat dairy products (which contain calcium) that is responsible. If you want to try calcium supplements, do not stop taking your blood pressure medication; talk to your doctor and let the doctor determine the proper dose of calcium for you. You may need to take calcium for 6 - 8 weeks before you see any improvement in blood pressure.

Some studies suggest that calcium supplementation may play a role in the prevention of pregnancy-induced high blood pressure and preeclampsia (a combination of high blood pressure, fluid retention, and high levels of protein in the urine that some women develop in the last trimester of pregnancy). However, not all studies show the same benefit. A prenatal vitamin, which provides magnesium, folic acid, and many other nutrients, together with adequate calcium intake through the diet, may lower the risk of developing high blood pressure during pregnancy.

Obesity

Some animal and human studies have found that consuming low-fat dairy products may help you lose or maintain a proper weight. However, researchers aren’t sure whether the calcium in the dairy products affects weight, some other nutrient -- or even a combination of nutrients. In addition, not all studies have found any benefit; and there’s no sound evidence that calcium supplements (as opposed to dairy products) would help in losing weight. More research is needed.

High Cholesterol

Preliminary studies in animals and people suggest that calcium supplements, in the range of 1,500 to 2,000 mg per day, may help to lower cholesterol slightly. From these studies, it appears that calcium supplements (along with exercise and proper diet) may be better at keeping cholesterol at normal levels than at lowering them once cholesterol is already high. More research in this area is needed.

Rickets

Rickets causes softening and weakening of the bone in children. Although virtually eliminated in North America and Western Europe, where milk consumption is common, it still occurs in many parts of the world. Researchers have thought that rickets is caused by a lack of vitamin D; however, a study in 2000 showed that calcium supplementation is an effective treatment.

Other Uses

Stroke -- In a population-based study (one in which large groups of people are followed over time), women who take in more calcium, both through their diet and with supplements, were less likely to have a stroke over a 14-year period. More research is needed.

Colon Cancer -- Although not all studies agree, some show that people who consume higher amounts of calcium, vitamin D, and milk in their diets are less likely to develop colorectal cancer than those who consume low amounts of the same nutrients. But researchers are not sure whether calcium supplements would have the same effect as calcium in the diet, or even whether calcium itself is responsible for the benefit.

Dietary Sources

The richest dietary sources of calcium include cheeses (such as parmesan, Romano, gruyere, cheddar, American, mozzarella, and feta), low-fat dairy products (milk, yogurt), tofu, and blackstrap molasses. Some other good sources of calcium include almonds, brewer's yeast, bok choy, Brazil nuts, broccoli, cabbage, dried figs, kelp, dark leafy greens (dandelion, turnip, collard, mustard, kale, Swiss chard), hazelnuts, oysters, sardines, and canned salmon,.

Foods that are fortified with calcium, such as juices, soy milk, rice milk, tofu and cereals, are also good sources of this mineral.

Available Forms

There are a number of forms of calcium available as dietary supplements. They differ in the amount of calcium they contain, how well they are absorbed by the body, and how much they cost. The two most popular forms are calcium citrate and calcium carbonate.

Calcium citrate: Easily absorbed and digested by the body, particularly in the elderly. It does not contain as much elemental calcium (the amount your body actually absorbs) as calcium carbonate. It is more costly than calcium carbonate, however. Also, calcium citrate should not be used with aluminum-containing antacids (see Possible Interactions).
Calcium carbonate: Less expensive than calcium citrate and contains more elemental calcium. Requires a certain amount of stomach acid to be absorbed, so it is usually taken with a glass of orange juice. Many antacids contain calcium carbonate.

Calcium supplements that are derived from oyster shells, dolomite, and bone meal are best avoided as they may contain lead, a toxic metal (particularly worrisome in children and those with kidney disease) that can harm the brain and kidneys, cause anemia, and raise blood pressure.

How to Take It

Calcium supplements should be taken in small doses (no more than 500 mg at a time -- that’s all your body can absorb in one dose) throughout the day with 6 - 8 cups of water to avoid constipation.

The following are daily dietary recommendations for general health and prevention of disease.

Pediatric

Talk to your pediatrician before giving a child any nutritional supplement.

Infants birth to 6 months: 210 mg
Infants 7 months to 1 year: 270 mg
Children 1 - 3 years: 500 mg
Children 4 - 8 years: 800 mg
Adolescents 9 - 18 years: 1,300 mg

Adult

19 - 50 years: 1,000 mg
51 years and older: 1,200 mg
Pregnant and breastfeeding females under 19 years: 1,300 mg
Pregnant and breastfeeding females 19 years and older: 1,000 mg

For prevention of colon cancer, 1,800 mg per day may be required.

Precautions

Because of the potential for side effects and interactions with medications, dietary supplements should be taken only under the supervision of a knowledgeable health care provider. Total calcium intake, from combined dietary and supplemental sources, should not exceed 2,500 mg per day.

Side effects can include constipation and stomach upset. Very high doses can cause nausea, vomiting, loss of appetite, increased urination, kidney toxicity, confusion, and irregular heart rhythm.

More generally, such high levels of calcium in the body occur when the body produces too much calcium. People with hyperparathyroidism, kidney failure, sarcoidosis, or cancer could be at risk for elevated levels of calcium and should not take calcium supplements.

People with a history of kidney stones should not take calcium supplements. However, some research suggests that calcium in the diet may not increase the risk of kidney stones. If you have or have had kidney stones, talk to your doctor about whether you should restrict calcium in your diet.

Men at risk for prostate cancer should avoid calcium supplements and also talk to their doctor about restricting low-fat dairy in their diets. Several studies have shown that higher intakes of calcium, whether from supplements or dairy products, are associated with greater risk of prostate cancer.

Possible Interactions

If you are currently being treated with any of the following medications, you should not use calcium supplements without first talking to your doctor.

Alendronate -- Calcium may interfere with the absorption of alendronate, a medication used to treat osteoporosis. Calcium-containing products should be taken at least 2 hours before or after alendronate.

Antacids that contain aluminum -- When calcium citrate is taken with aluminum-containing antacids, the amount of aluminum absorbed into the blood may be increased significantly. This is a particular problem for people with kidney disease, for whom the aluminum levels may become toxic.

Blood pressure medications -- Taking calcium with a beta-blocker (such as atenolol) may interfere with blood levels of both the calcium and the beta-blocker. Study results are conflicting, however. Similarly, it has been reported that calcium interferes with calcium channel blockers (such as verapamil), but these study results are also controversial. If you take a beta-blocker or calcium-channel blocker, do not take calcium supplements without your doctor’s supervision.

Cholesterol-lowering medications -- A class of medications known as bile acid sequestrants (including cholestyramine, colestipol, and colesevelam), used to treat high cholesterol, may interfere with normal calcium absorption and increase the loss of calcium in the urine. Supplementation, therefore, with calcium and vitamin D may be recommended by your health care provider.

Corticosteroids -- If you take corticosteroids on a long-term basis, you may need to take calcium supplements.

Digoxin -- High levels of calcium may increase the risk of a toxic reaction to digoxin, a medication used to treat irregular heart rhythms. On the other hand, low levels of calcium cause digoxin to be ineffective. If you take digoxin, your doctor should monitor your calcium levels closely.

Diuretics -- Different types of diuretics interact with calcium in opposite ways.

Thiazide diuretics (such as hydrochlorothiazide) can raise calcium levels in the blood.
Loop diuretics (such as furosemide and bumetanide) can decrease calcium levels.
Amiloride (a potassium-sparing diuretic) may decrease the amount of calcium excreted in the urine (thus increasing calcium levels in the blood), especially in people with kidney stones.

Estrogens -- Estrogens may contribute to an overall increase in calcium blood levels. Taking calcium supplements with estrogens improves bone density significantly.

Gentamicin -- Taking calcium during treatment with the antibiotic gentamicin may increase the potential for toxic effects on the kidneys.

Antibiotics -- Different types of antibiotics interact with calcium.

Quinolones: Calcium can interfere with the body's ability to absorb quinolone antibiotics (such as ciprofloxacin or Cipro; levofloxacin, norfloxacin or Noroxin; and ofloxacin). Take calcium supplements 2 - 4 hours before or after taking quinolone antibiotics
Tetracyclines: Calcium can interfere with the body's ability to absorb tetracycline antibiotics (including doxycycline, minocycline, and tetracycline). Take calcium supplements 2 -4 hours before or after taking quinolone antibiotics.

Anti-seizure medications -- Some seizure medications, such as phenytoin (Dilantin), carbamazepine, phenobarbitol, and primidone, may lower levels of calcium in the body. Some doctors recommend vitamin D along with anti-seizure drugs to try to keep calcium levels up. In addition, you should take doses of calcium and anti-seizure medications at least 2 hours apart, because each interferes with the absorption of the other.

HEALTH GUIDE REFERENCE FROM A.D.A.M

Rheumatoid arthritis (RA) is a long-term (chronic) disease that causes inflammation of the joints and surrounding tissues. It can also affect other organs.

RA destroys the protective tissue (cartilage) surrounding the joints. Healthy cartilage allows bones to glide smoothly over one another, and absorbs the shock of physical movement. With RA, the cartilage breaks down and wears away. As a result, the bones rub together. Patients with this disease have joint swelling, pain, and stiffness.

RA usually affects joints on both sides of the body equally. Wrists, fingers, knees, feet, and ankles are the most commonly affected.

Signs and Symptoms

RA usually develops slowly over time, with the following symptoms:

Morning stiffness -- waking up with stiff joints (often the wrists and base of the fingers, ankles, balls of the feet, elbows, or knees)
Joint pain with warmth, swelling, tenderness, and stiffness of the joint after inactivity
Limited range of motion in the affected joints
Fatigue
Low grade fever (when joints are acutely inflamed)
Small, round, firm bumps (called nodules) under the skin; you can feel these, but they are generally painless

Juvenile rheumatoid arthritis (JRA, also known as Still's disease) is usually preceded by a high fever and shaking chills. A pink skin rash may also be present.

Causes

The cause of RA is unknown. It is considered an autoimmune disease. The body's immune system normally fights off foreign substances, like viruses. But in an autoimmune disease, the immune system confuses healthy tissue for foreign substances. As a result, the body attacks itself.

RA can occur at any age. It usually occurs in people between 25 - 55 years of age. Women are affected more often than men.

The course and the severity of the illness can vary considerably. Infection, genes, and hormones may contribute to the disease.

RA usually affects joints on both sides of the body equally. Wrists, fingers, knees, feet, and ankles are the most commonly affected.

Risk Factors

Age. Although the disease can occur at any age, RA generally starts in young adulthood usually between ages 25 and 55. Juvenile rheumatoid arthritis affects 70,000 - 75,000 children in the United States.
Female. Women are affected two and a half times more often than men, and have a greater chance of having a severe case.
Family history. Having relatives with this type of arthritis increases your risk of getting it yourself.
Cigarette smoking. It appears that heavy smoking over a long period of time increases your risk of getting RA.
Coffee intake. This is controversial. One Finnish study reported a direct association between coffee consumption and an increased risk for RA, but the study did not account for other factors, such as the way coffee is prepared in Finland (typically without filters). A study in the U.S. of 121,701 women found little evidence of an association between coffee or decaf coffee and the risk of RA. Further investigation is needed.
Medication. Interferon-alpha, a drug used to treat hepatitis, autoimmune diseases, and other diseases has triggered RA in rare cases.

Other risk factors include:

History of blood transfusions

RA can be difficult to diagnose because it resembles many other conditions, and symptoms develop so gradually they can go unnoticed. Even after RA has been diagnosed, it is extremely important to determine how the disease is progressing in order to treat it appropriately.

Your doctor will take your medical history and perform a physical exam. Blood tests, x-rays, and aspiration (the removal of fluid from the joint) may also be needed. A blood test may be performed to determine if an antibody called rheumatoid factor is present. Most patients with rheumatoid arthritis eventually have this abnormal protein in their blood. However, it may not present when symptoms first develop. If rheumatoid factor is present, a positive diagnosis is made. If patients test negative but rheumatoid arthritis is suspected, a health care provider may recommend treatment to reduce symptoms. Another test may be performed in the future to confirm a diagnosis.

Treatment Approach

RA usually requires lifelong treatment, including various medications, physical therapy, education, and possibly surgery. Treatment is aimed at relieving symptoms and preserving joint function.

Regular visits to your health care provider will be necessary to monitor the progress of the disease and side effects of drugs you may be taking. This might also entail regular blood and urine tests.

Frequently, the disease can be controlled with a combination of treatments. Treatment may vary depending on the severity of the symptoms. Surgery may be needed, if medications fail.

For the past 10 years, studies have shown that early, aggressive treatment for RA can delay the onset of joint destruction. In addition to rest, strengthening exercises, and anti-inflammatory agents, the current standard of care is to start therapy with disease-modifying anti-rheumatic drugs (DMARDs) -- these are drugs that actually alter the course of the disease rather than just relieve symptoms. Studies show that certain dietary supplements, particularly omega-3 fatty acids, show promise in helping to relieve symptoms. Other symptom-relieving measures might include bathing in sulfur baths or warm pools, applying capsaicin to the skin for pain, and having electrical stimulation to increase muscle strength.

Lifestyle

Range of motion exercises and individualized exercise programs prescribed by a physical therapist can help to maintain joint motion and strength and delay the loss of joint function.

Joint protection techniques, such as heat and cold treatments and splints or orthotic (straightening) devices to support and align joints, may be very helpful.

Medications

The following drugs are used to treat RA:

Disease-modifying anti-rheumatoid drugs (DMARDs) methotrexate is used most often.
Aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) -- NSAIDS are commonly used to relieve joint pain and inflammation. Although NSAIDs work well, long-term use can cause stomach problems, such as ulcers and bleeding, and possible heart problems. In April 2005, the U.S. Food and Drug Administration (FDA) asked drug manufacturers of NSAIDs to include a warning label on their product to alert users of an increased risk for heart problems and gastrointestinal bleeding.
Cyclo-oxgenase-2 (COX-2) inhibitors -- COX-2 inhibitors block an inflammation-promoting enzyme called COX-2. This class of drugs was initially believed to work as well as traditional NSAIDs, but with fewer stomach problems. However, numerous reports of heart attacks and stroke have prompted the FDA to re-evaluate the risks and benefits of the COX-2s. Rofecoxib (Vioxx) and valdecoxib (Bextra) were withdrawn from the U.S. market following reports of heart attacks in patients taking the drugs. Celecoxib (Celebrex) is still available, but it is labeled with strong warnings and a recommendation that it be prescribed at the lowest possible dose for the shortest duration possible. Patients should ask their doctor whether the drug is appropriate and safe for them.
Corticosteroids -- Also known as steroids, these medications are injected directly into the joint. They may also be used to reduce inflammation and pain. Steroids for inflammation inlclude prednisone (Deltasone) and dexamethasone (Decadron). Steroids, however, may cause side effects such as weight gain, nausea, and fluid accumulation (edema). Steroids may also cause drug interactions. Ask a pharmacist or doctor.
Immune suppressants -- used for serious cases of RA when all other medications have failed. These include azathioprine (Imuran) and cyclophosphamide (Cytoxan).
Tumor necrosis factor (TNF) modifiers -- such as rituximab (Rituxan) and infliximab (Remicade®). Both are FDA-approved for moderate-to-severe cases of RA. These drugs block TNFs (inflammatory proteins). They are injected into an IV.

Surgery and Other Procedures

Occasionally, surgery may be required to treat severely affected joints. The most successful surgeries are those on the knees and hips. Removal of the synovium (called synovectomy) is a common surgical procedure.

A later alternative is total joint replacement with a prosthesis (an artificial joint). Surgeries may relieve pain, correct deformities, and modestly improve joint function. In extreme cases, total knee or hip replacement can mean the difference between being completely dependent on others and having an independent life at home.

Nutrition and Dietary Supplements

Diet. It is important to eat a nutritious diet full of whole foods, including protein, which is needed in the body's healing process. Foods rich in B vitamins, vitamin E, zinc, and selenium may be particularly important. Although several types of diets may be effective for RA, no one diet has been found to work for everyone.

There are reports of people with RA who experienced an improvement in their symptoms when they switched from a typical Western diet (high in animal protein and simple sugars) to a vegan diet with lots of uncooked berries, fruits, vegetables, nuts, roots, seeds, and sprouts. Vegan diets contain no animal products and obtain protein from vegetable sources.

Elimination/provocation diets (also called elimination/re-challenging diets), are designed to detect allergens by systematically taking certain foods out of the diet and reintroducing them one at a time. Such diets should be strictly supervised by a qualified physician or dietitian. If this process is followed, you should keep careful track of your symptoms in a food diary to see if the dietary changes impact your symptoms.

These general nutritional tips may help reduce symptoms:

Remove known food allergens or irritants. The most common food allergens are dairy products, wheat, corn, peanuts, citrus, soy, eggs, fish, and tomatoes. Your health care provider may want to test for food sensitivities.
Avoid refined foods such as white breads, pastas, and sugar.
Eat fewer red meats and more lean meats, cold-water fish, tofu (soy, if no allergy) or beans for protein.
Use healthy cooking oils, such as olive oil or vegetable oil.
Reduce or eliminate trans-fatty acids, found in commercially baked goods such as cookies, crackers, cakes, French fries, onion rings, donuts, processed foods, and margarine.
Taking digestive enzymes 20 minutes before meals can help enhance digestion and normalize bowel function.
Avoid coffee and other stimulants, alcohol, and tobacco.
Drink 6 - 8 glasses of filtered water daily.
Exercise where possible, 30 minutes daily, 5 days a week.

Nutritional deficiencies may be addressed with the following supplements:

Glucosamine/chondroitin, 500 - 1,500 mg daily, for joint health.
Omega-3 fatty acids, such as fish oil, 1 - 2 capsules or 1 tablespoonful oil daily, to help decrease inflammation and improve immunity.
A multivitamin daily, containing the antioxidant vitamins A, C, D, E, the B-vitamins and trace minerals, such as magnesium, calcium, zinc, and selenium.
Coenzyme Q10, 100 - 200 mg at bedtime, for antioxidant and immune support.
Alpha-lipoic acid, 25 - 100 mg twice daily, for antioxidant effects.
N-acetyl cysteine, 200 mg daily, for antioxidant effects.
Probiotic supplement (containing Lactobacillus acidophilus), 5 - 10 billion CFUs (colony forming units) a day, for maintenance of gastrointestinal and immune health. Some probiotic supplements may need refrigeration for best results. Check the label carefully.
Grapefruit seed extract (Citrus paradisi), 100 mg capsule or 5 - 10 drops (in favorite beverage) three times daily, for antibacterial or antifungal activity and immunity.
Vitamin C, 500 - 1,000 mg one to three times daily, as an antioxidant, and for immune support.
SAMe (s-adenosyl-L-methionine), 100 - 200 mg before breakfast daily, for joint health.
L-theanine, 200 mg one to three times daily, for stress and nervous system support.

Herbs.You can use herbs in the form of dried extracts (capsules, powders, teas), glycerites (glycerine extracts), or tinctures (alcohol extracts). Unless otherwise indicated, make teas with 1 tsp. herb per cup of hot water. Steep covered 5 - 10 minutes for leaf or flowers, and 10 - 20 minutes for roots. Drink 2 - 4 cups per day.

Green tea (Camelia sinensis) standardized extract, 250 - 500 mg daily, for antioxidant effects. Use caffeine-free products. You may also prepare teas from the leaf of this herb.
Cat's claw (Uncaria tomentosa) standardized extract, 20 mg three times a day, for inflammation and antibacterial or antifungal activity.
Reishi mushroom (Ganoderma lucidum), 150 - 300 mg two to three times daily, for inflammation and for immunity. You may also take a tincture of this mushroom extract, 30 - 60 drops two to three times a day.
Olive leaf (Olea europaea) standardized extract, 250 - 500 mg one to three times daily, for antibacterial or antifungal activity and immunity. You may also prepare teas from the leaf of this herb.
Bromelain (Ananus comosus) standardized, 40 mg three times daily, for pain and inflammation.
Turmeric (Curcuma longa) standardized extract, 300 mg three times a day, for pain and inflammation.
Devil's claw (Harpagophytum procumbens) standardized extract, 100 - 200 mg one to two times daily, for inflammation.
Willow bark (Salix alba) standardized extract, 500 mg up to three times daily.

Capsaicin (Capsicum frutescens) Cream

Capsaicin is the main component in hot chili peppers (also known as cayenne). Researchers believe that when applied to the skin, it may deplete stores of a substance that contributes to inflammation and pain in arthritis. Pain reduction generally begins three to seven days after initially applying the capsaicin cream to the skin, but may be most pronounced after about four weeks of use. Wash hands well with vinegar after use and avoid touching the eyes.

Acupuncture

There is little to no scientific evidence supporting the use of acupuncture for RA. However, there is much anecdotal evidence to support trying acupuncture for symptom relief and improvement in overall health in patients with RA. Acupuncturists treat people with RA based on an individualized assessment of the excesses and deficiencies of qi, or energy, located in various meridians. A qi deficiency is usually detected in the spleen and kidney meridians.

Acupuncturists may use moxibustion [a technique in which the herb mugwort (Artemesia vulgaris) is burned over specific acupuncture points] to strengthen the entire energy system. Qualified acupuncturists may also provide lifestyle, dietary, and herbal advice to people with RA. Practitioners may apply local treatment to the painful areas and related sore points, either with a needle or moxibustion. However, given the current lack of evidence, acupuncture should be used as a supportive treatment with conventional medical therapy.

Chiropractic

Chiropractors do not treat red, swollen joints, and high velocity chiropractic manipulation is considered inappropriate in areas of the body affected by this condition. However, some chiropractors report that spinal manipulation may decrease pain and enhance joint mobility when used in between flare ups for people with RA.

Exercise

It is important to maintain a balance between rest (which will reduce inflammation) and exercise (which will relieve stiffness and weakness). Clinical studies suggest that as little as three hours of physical therapy over six weeks will help you people who have RA, and these benefits are sustained.

The goal of exercise is the following:

To maintain a wide range of motion
To increase strength, endurance, and mobility
Improve general health
Promote well-being

While traditional guidelines have restricted RA patients to only gentle exercise, research suggests that more intense exercise may not only be safe, but may actually produce greater muscle strength and overall functioning. Signs from your body are the best guides for how long or hard you should exercise.

If you feel sharp pains while exercising, stop immediately.
If lesser aches and pains continue for more than 2 hours afterwards, try a lighter exercise program for awhile.
Using large joints instead of small ones for ordinary tasks can help relieve pressure. For example, use your hip to close doors or the palm of your hand to push buttons.

Balneotherapy (Hydrotherapy or spa therapy)

Balneotherapy is one of the oldest forms of therapy for pain relief for people with arthritis. The term "balneo" comes from the Latin word for bath (balneum) and refers to bathing in thermal or mineral waters. For example, sulfur-containing mud baths have been shown to relieve symptoms of arthritis. The goals of balneotherapy for arthritis include:

Improving range of joint motion
Increasing muscle strength
Eliminating muscle spasm
Enhancing functional mobility
Easing pain
Exercising and swimming in a heated pool may also be beneficial

Mechanical Aids

A variety of mechanical devices, called orthoses, are available for people with RA to help support and protect joints. Made from lightweight metal leather, elastic, foam, and plastic, orthoses allow some movement within the affected joint and do not restrict nearby joints. For example, splints or braces help align joints and properly distribute weight. Shock-absorbing soles in shoes can help in daily activities and during exercise. These mechanical aids are used most frequently to treat arthritic hands, wrists, knees, ankles, and feet. A physical or occupational therapist should custom-fit orthoses.

Compression gloves are another potentially helpful aid. Two studies on the overnight use of compression gloves (close-fitting nylon-spandex gloves) concluded that the gloves reduced pain and stiffness in people with RA in the fingers.

Other possibilities for symptom relief include:

Transcutaneous nerve stimulation (TENS) -- small clinical studies show that at 70Hz, TENS, a technique used by many physical therapists, may provide short-term pain relief for people with RA
Magnetic devices -- devices employing static magnetic fields may help reduce pain
Heat and cold applications -- some people find these applications comforting; may reduce pain

Homeopathy

Recent trials evaluating the use of homeopathy in the treatment of RA found that the remedies were no more effective than placebo in reducing symptoms. These studies contradict an older trial that showed beneficial effects with homeopathic treatment. Despite the lack of definitive evidence, professional homeopaths might recommend one of the following treatments for RA based on their knowledge and clinical experience, as well as successful trials for homeopathy to treat OA. Before prescribing a remedy, homeopaths take into account an individual's constitutional type-- your physical, emotional, and intellectual makeup. An experienced homeopath assesses all of these factors when determining the most appropriate remedy for a particular individual.

Potential remedies include:

A topical homeopathic gel containing comfrey (Symphytum officinale), poison ivy (Rhus toxicodendron), and marsh-tea (Ledum palustre)
A combination homeopathic preparation containing R. toxicodendron, Arnica Montana (arnica), Solanum dulcamara (climbing nightshade), Sanguinarra Canadensis (bloodroot), and Sulphur
A liquid homeopathic preparation containing R. toxicodendron, Causticum (potassium hydrate), and Lac vaccinum (cow's milk)

Mind-Body Medicine

Chronic pain and disability can make daily functioning difficult. A holistic approach to your care may positively affect both your lifestyle and how you feel overall. Many people report that relaxation techniques, such as guided imagery and meditation, are an important part of general care and help alleviate pain and other symptoms of RA.

Yoga

This ancient Indian practice is well known for its physical, psychological, emotional, and spiritual benefits and is often recommended to relieve musculoskeletal symptoms. People with arthritis should begin asanas slowly and they should be performed only after a warm up. Yoga is best performed under the careful guidance of a reputable instructor.

Tai Chi

This gentle exercise program practiced in China for centuries has been shown to produce a number of benefits, including the following:

Improved fitness
Increased muscular strength
Enhanced flexibility
Reduced percentage of body fat
Diminished risk of falls in the elderly

Several clinical trials have found that Tai Chi produces significant improvement in those with rheumatoid arthritis. Improvements were found in:

Overall sense of quality of life
Diminished feelings of stress/tension
Increased satisfaction with general health
Decreased fatigue
Easier self management of arthritis symptoms

These benefits are likely to apply to individuals with RA as well. A review of the literature found that Tai Chi benefits lower extremity range of motion for people with RA.

Other Considerations

Prognosis and Complications

RA is associated with many complications.

Joint deformities
Cervical spine problems (can be life threatening)
Painless, hard, round or oval masses called nodules that appear under the skin
Pleuritis (inflammation of the lungs)
Anemia
Rheumatoid vasculitis (inflammation of the blood vessels)
Pericarditis (inflammation of the outer lining of the heart)
Myocarditis (inflammation of the heart muscle)
Heart failure
Eye inflammation

The course of the disease varies between individuals. People with a certain antibody in the blood (rheumatoid factor) or nodules seem to have more severe disease. People who develop RA at younger ages also tend to have faster disease progression.

Remission is most likely to occur in the first year and decreases over time. About 20% of people will experience remission and be able to care for themselves 10 - 15 years after diagnosis.

Although complications may shorten the life expectancy of people with RA, treatment is constantly improving and the occurrence of severe disability and life-threatening complications appears to be decreasing.
