Neti pot solution: Can I make my own?

A neti pot is a container designed to rinse the nasal cavity. Neti pots are often used to treat nasal congestion, sinus problems and colds. When you use a neti pot, a homemade saltwater solution is just as effective as an over-the-counter nasal saline rinse or buffered neti pot solution. To make your own neti pot solution, simply dissolve 1/8 teaspoon of table salt into 8 ounces of distilled or purified water — which contains no chlorine or other impurities. You can also use tap water, as long as you bring it to a boil and then cool it to room temperature before you add the salt. . read more.

Ozone air purifiers: Can they improve asthma symptoms?

Despite manufacturers' claims, ozone air purifiers don't remove asthma triggers from the air. In fact, inhaled ozone can make asthma worse. Ozone generators sold as air purifiers intentionally produce the gas ozone. Ozone can mask odors by changing the chemical composition of particles or other gasses in the air, making the air seem fresher and cleaner. However, ozone generators don't actually filter out the small particles that trigger asthma. Inhaling ozone, even in small amounts, can irritate the lungs. Specific effects may include throat irritation, coughing, chest pain and shortness of breath, as well as an increased risk of respiratory infections. . read more.

Pet allergy: Are there hypoallergenic dog breeds?

There is no such thing as a hypoallergenic dog breed, although some breeds may cause fewer allergy symptoms than others. Many people think that pet allergies are caused by a dog's or cat's fur, but the real source of pet allergies is often a protein that's in the saliva and urine of dogs and cats. This protein sticks to the dead, dried flakes (dander) from your pet's skin. Some dog breeds, such as the soft-coated wheaten terrier, or mixed breeds such as the goldendoodle, are marketed as hypoallergenic dogs because they don't shed fur or they shed very little. . read more.

New Rules for Food Allergies: Fewer Children May Be Diagnosed as Doctors Told Not to Rely Solely on Standard Skin and Blood Tests

Parents who have eliminated foods from their children's diets based on allergy tests alone may find that some are safe to eat after all. The National Institute for Allergy and Infectious Diseases issued the first clinical guidelines for diagnosing and treating food allergies Monday, saying that blood or skin tests aren't sufficient when making a diagnosis. An allergy should be suspected if someone has a reaction within minutes or hours of eating a food, according to the guidelines. Physicians should then take a detailed medical history, conduct a physical exam and confirm the allergy with a skin-prick test, in which tiny drops of the suspected allergen are pricked into the skin, usually in the forearm, to see if red wheals form. None of those steps is definitive by itself, the recommendations say, which will likely to lead to fewer diagnoses. . read more.

Guidelines for the Diagnosis and Management of Food Allergy in the United States: What's in It for Patients

Approximately 1 in 20 children and about one in 25 adults have a food allergy. If you have a food allergy, then the more you know and understand about the disease and its diagnosis and management, the better you will be able to discuss your care with your doctor. The Guidelines for the Diagnosis and Management of Food Allergy in the United States: Report of the NIAID-sponsored Expert Panel is a report developed by a 25-member expert panel to help healthcare professionals, including family practice physicians, medical specialists, and nurses, to better care for their patients with food allergy. The guidelines are based on the most up-to-date scientific and clinical information about food allergy and the consensus expert opinion of the panel members. . read more.

The Claim: A Cup of Coffee can Ease the Symptoms of Asthma

Caffeine is known more as a pick-me-up than a home remedy, but for years scientists have wondered whether it may have benefits for people with asthma. The suspicion stems in part from its chemical structure, which resembles that of theophylline, a common asthma medication that relaxes the airway muscles and relieves wheezing, shortness of breath and other respiratory problems. Indeed, when caffeine is ingested and broken down by the liver, one byproduct is small amounts of theophylline. . read more.

Food-Allergy Fears Drive Overly Restrictive Diets, Study Suggests

Many children, especially those with eczema, are unnecessarily avoiding foods based on incomplete information about potential food-allergies, according to researchers at National Jewish Health. The food avoidance poses a nutritional risk for these children, and is often based primarily on data from blood tests known as serum immunoassays. Many factors, including patient and family history, physical examination, and blood and skin tests, should be used when evaluating potential food allergies. . read more.

Pregnancy and Peanuts: Tricky Truths About Food Allergies

Sitting down to a meal can be daunting for an expectant mother weighing conflicting recommendations about which foods are good for her unborn child -- and which might subject that child to long-term ills like allergies to peanuts and other foods. "We have a tendency to beat pregnant women over the head with 'do this, don't do this,'" said obstetrician-gynecologist Dr. Laura Riley, medical director of labor and delivery at the Harvard-affiliated Massachusetts General Hospital. "We always want people to have a balanced diet that includes protein, fat and carbohydrates. We don't think pregnant women should take any one thing out of their diet." But just as dietary advice for weight loss changes as new scientific information becomes available, so, too, does dietary advice for moms-to-be about how their eating shapes their future sons' and daughters' health. . read more.

If Kissing or Sex Leaves You Tingly, Is It Love or Allergies?

Even brushing your teeth – or waiting hours after eating may not prevent some partners of people with food and medicine allergies from triggering an allergic reaction through a kiss. “If you have food allergies, having an allergic reaction immediately after kissing someone who has eaten the food or taken oral medication that you are allergic to isn’t highly unusual,” said allergist Sami Bahna, MD. “But some patients react after their partner has brushed his or her teeth or several hours after eating. It turns out that their partners’ saliva is excreting the allergen hours after the food or medicine has been absorbed by their body.” "Kissing" allergies are most commonly found in people who have food or medication allergies. Symptoms include swelling of the lips or throat, rash, hives, itching and wheezing. Food allergies affect about 2 to 3 percent of adults and 5 to 7 percent of children in the U.S. population, or more than 7 million people. So what are lovebirds to do? . . read more.

Allergic to Bed Bugs? Allergists detect, treat often overlooked bites

Want another reason to fear bed bugs? They can sometimes set off allergic reactions, asthma attacks and anaphylaxis. Most individuals bitten by bed bugs get red bite marks that are mildly itchy. But those who are allergic can experience intense itching, swelling, redness, hives and blisters. The bugs can trigger asthma if a large group of them become airborne. And, although rare, those who are highly allergic to the bites may experience anaphylaxis, a life-threatening reaction that can cause trouble breathing, hives or swelling or tightness of the throat. . read more.

Allergists Can Provide Action Plan to Help Acute Peanut Allergy Sufferers

Living with an acute peanut allergy is difficult, scary and potentially life-threatening, but that doesn’t mean schools and airlines should totally eliminate peanuts from their surroundings, according to Sami Bahna, MD, president of the American College of Allergy, Asthma and Immunology (ACAAI). People with severe peanut allergies can work with their allergist to develop an action plan to prevent or manage attacks. “Highly allergic people may react after ingesting minute hidden quantities of peanuts or even after touching or smelling peanuts. These patients often live in fear they will come in contact with peanuts,” said Dr. Bahna. “There are ways to make life livable and less frightening, but there is no guarantee that specific allergens can be removed entirely from an environment.” Food allergies are serious and sources of the allergen can be hidden. Peanuts can easily be inadvertently eaten, especially outside of the home. Packaged products may contain peanut allergens, cooks can accidentally share utensils or oils, and patrons can inhale vapors from tableside cooking. . read more.

Hold the Phone: Prolonged Cell Use Can Trigger Allergic Reaction. . Body Piercing, Tattoos and Cosmetics Spark Allergies, Too

Chatting endlessly on your cell phone can lead to an allergic reaction to the nickel in your phone. From cosmetics to jewelry, body piercings to tattoos, allergies can lurk in unlikely places, allergists say. “Increased use of cell phones with unlimited usage plans has led to more prolonged exposure to the nickel in phones,” said allergist Luz Fonacier, MD. “Patients come in with dry, itchy patches on their cheeks, jaw lines and ears and have no idea what is causing their allergic reaction.” Nickel is one of the most common contact allergens, and affects up to 17 percent of women and 3 percent of men. Contact with objects containing nickel, such as keys, coins and paper clips are generally brief, so the nickel allergy may not occur on the area of contact. However, even in these brief encounters, nickel can be transferred from fingers to the face and cause eyelid irritation. The risk is increased by frequent, prolonged exposure to nickel-containing objects, such as cell phones, jewelry, watches, and eye-glass frames. . read more.

Eye Allergies Often Overlooked, Undertreated: Relief Available for Millions of Americans with Itchy, Gritty, Watery Eyes

Millions of Americans suffer unnecessarily with itchy, gritty, watery eyes. The underdiagnosis, undertreatment and self-treatment of eye allergies may seriously diminish quality of life, allergists say. “For every one eye allergy medicine prescribed, 40 people are treating themselves with over-the-counter eye medicine from their local pharmacy,” allergist Leonard Bielory, MD. “The over-the-counter product may relieve the symptoms for a short time, but long-term, these patients need to see an allergist who can develop a complete treatment plan to eliminate the disease.” Eye allergy symptoms are regularly reported as one of the top three allergy complaints, according to the Allergies in America Survey. Forty percent of adults in the United States experience eye allergies and more than 40 million bottles of eye allergy medicine are sold in the U.S. each year. . read more.

Chinese herbs can complement proven allergy treatments: Herbal formula shows promise against food allergies

Complementary and alternative medicine may give allergy and asthma sufferers new options for treating symptoms, according to allergists at the annual scientific meeting of the American College of Allergy, Asthma and Immunology (ACAAI). Allergists discussed how herbal treatments may be integrated into conventional allergy treatments, including a novel Chinese herbal formula for treating all types of food allergies. “Integrative therapies blend the art and science of medicine,” said allergist William Silvers, MD. “This exciting area of medicine offers a variety of complementary approachments, so each patient receives truly individualized care.” One promising remedy is the Food Allergy Herbal Formula (FAHF-2), a Chinese herbal formula currently being tested for use to treat food allergies. Early research showed significant reduction in peanut-induced anaphylaxis in mice. Phase I clinical studies have shown that FAHF-2 is safe in humans. . read more.

Hate taking allergy drugs? get better with immunotherapy - Tested for 100 Years – New Advancements

Antihistamines and nasal steroids offer good short-term options for people with mild allergy, but allergy immunotherapy, better known as “allergy shots,” is a preferred method for achieving long term remission of more bothersome allergy symptoms. Allergy immunotherapy is the only allergy treatment that has been shown to prevent the progression of allergic disease, reduce the risk of developing asthma, and provide long term remission after therapy ends. Studies demonstrate it reduces the need for medication, as well as use and cost of health care services. And unlike medications, allergen immunotherapy has a long track record of safety in children, the elderly and pregnant women. Beginning with the first published study on inoculation against grass pollen in 1911, allergy immunotherapy has been proven over the past century as a safe, effective treatment against allergens including pollen, mold, insects and animals, and also for allergic asthma. The treatment stops the source of the patient’s suffering rather than just treating the symptoms. . read more.

Pumpkin Pie not a treat for some allergic children: Pediatric Hot Topics Reveal New Conclusions on Pumpkin, Caterpillars and More

Your child may be allergic to your holiday pumpkin pie, according to allergists at the annual scientific meeting of the American College of Allergy, Asthma and Immunology (ACAAI). Hot topics discussed in pediatric allergies include pumpkin and caterpillar allergies, and outgrowing childhood allergies. Although pumpkin is not a food usually associated with allergic reactions, allergists reported a case study of an 8-year-old boy with known asthma and food allergies who became sick after carving a pumpkin. His symptoms included itchy eyes, sneezing, eyelid swelling and chest tightness. Allergists say these symptoms can occur after carving or eating pumpkin. . read more.

Americans abandoning prescriptions when faced with costs

Americans with health insurance are increasingly abandoning their prescriptions at the pharmacy counter, according to a review of insurance-claims data by Wolters Kluwer Pharma Solutions. This so-called “abandonment,” when a patient refuses to purchase or pick up a prescription that was filled and packaged by a pharmacist, increased by 55 percent during second quarter of 2010, compared with four years earlier. Patients are not picking up the most expensive drugs most often, according to the study. . read more.

I think I may have an aspirin allergy. What are the symptoms?

Reactions to aspirin are common. If you have an aspirin allergy or sensitivity, you may also have a reaction to other nonsteroidal anti-inflammatory drugs (NSAIDs), including ibuprofen (Advil, Motrin, others) and naproxen (Aleve, others). An aspirin allergy or sensitivity, or a reaction to another NSAID, can cause symptoms that range from mild to severe. Reactions generally occur within a few hours of taking the medication. . read more.

Sulfa allergy: Which medications should I avoid?

How can I tell if a medicine contains sulfa? Should I simply avoid those with ingredients that have the prefix "sul" or "sulfa"? . . Avoiding only medications with the prefix "sul" or even "sulfa" is not a good rule of thumb if you have a sulfa allergy. The term "sulfa allergy" is most often used to describe an adverse drug reaction to antibiotics that contain sulfonamides. Generic names or brand names of medications that contain sulfonamides may not start with "sul" or "sulfa." . . read more.

New Study Re-examines Bacterial Vaccine Studies Conducted During 1918 Influenza Pandemic

Secondary infections with bacteria such as Streptococcus pneumoniae, which causes pneumonia, were a major cause of death during the 1918 flu pandemic and may be important in modern pandemics as well, according to a new article in the Journal of Infectious Diseases. The new analysis suggests that the use of bacterial vaccines containing S. pneumoniae could reduce pneumonia rates and deaths in modern influenza pandemics. During the 2009-2010 H1N1 influenza pandemic, the authors write, autopsy results implicated bacterial infections in 29 to 55 percent of deaths. . read more.

Egg Allergy No Longer a Reason to Avoid Getting a Flu Vaccine

Along with fall comes flu season, but having an egg allergy is not a reason to avoid getting the 2010-2011 flu vaccination. According to a new paper published on the American Academy of Allergy, Asthma & Immunology (AAAAI) website, recent studies show that most egg allergic individuals can receive the flu vaccine safely under the care of their allergist/immunologist. . read more.

Deployment to Iraq linked to higher asthma risk

During the early stages of the Iraq War a research team began investigating diagnoses of new-onset asthma among deployed soldiers. Their research finds that among the 6,233 troops on active duty from 2004-07, the rate of new-onset asthma was 6.6% for Iraq-deployed soldiers and 4.4% for stateside-based ones. A total of 290 new-onset cases were identified between both groups. The relative odds of coming back from deployment in Iraq with new-onset asthma was 1.58 times (or 158%) and this association held for both genders and all age groups. . read more.

Vocal cord dysfunction: Is it a type of asthma?

Although they can have similar triggers and symptoms, vocal cord dysfunction is not the same as asthma. With asthma, exposure to a lung irritant triggers the release of immune system chemicals that cause the airways (bronchial tubes) to tighten and produce excess mucus. With vocal cord dysfunction, also called paradoxical vocal cord movement and laryngeal dysfunction, vocal cord muscles tighten and make breathing difficult. Unlike asthma, vocal cord dysfunction isn't an allergic reaction and doesn't involve the lower airways. Because they have similar triggers and symptoms, it's common for vocal cord dysfunction to be misdiagnosed as asthma. . read more.

Reactive airway disease: Is it asthma?

Sometimes the terms "reactive airway disease" and "asthma" are used interchangeably. However, they're not necessarily the same thing. Reactive airway disease is a general term that doesn't indicate a specific diagnosis. . read more.

Asthma and acid reflux: Are they linked?

Asthma and acid reflux often occur together. It isn't clear why, or whether one causes the other. What we do know is that acid reflux can worsen asthma — and asthma can worsen acid reflux. This can be particularly true if you have severe acid reflux, a condition known as gastroesophageal reflux disease (GERD). . read more.

Asthma without wheezing: Is this possible?

Yes, it's possible to have asthma without wheezing. A wheeze is a whistling sound produced by air flowing through a narrowed airway. Although a wheeze occurs primarily on exhaling, it can be heard on inhaling as well. Wheezing is a common sign of asthma, particularly in children. However, asthma doesn't always produce a wheeze you can hear. . read more.

Severe Food Allergies Turned Off in Mice

Johns Hopkins scientists have discovered a way to turn off the immune system's allergic reaction to certain food proteins in mice, a discovery that could have implications for the millions of people who suffer severe reactions to foods, such as peanuts and milk. The findings, published online in the journal Nature Medicine, provide hope that the body could, under close medical supervision, be trained to tolerate food allergies that lead to roughly 300,000 emergency room visits and 100 to 200 deaths each year. . read more.

LABAs for asthma — Should I stop taking them?

In some studies, long-acting beta agonists (LABAs) have been linked to life-threatening asthma attacks. The risk appears to be greatest when a LABA is used without also using an inhaled corticosteroid. In contrast, taking an inhaled corticosteroid along with a LABA is appropriate treatment for many people who have asthma. Don't stop any of your asthma medications before checking with your doctor first. . read more.

Humidifiers: Air moisture eases skin, breathing symptoms

Humidifiers can ease problems caused by dry air. But they need regular maintenance. Here are tips to ensure your humidifier doesn't become a household health hazard: Dry sinuses, bloody noses and cracked lips — humidifiers can help soothe these familiar problems caused by dry indoor air. Humidifiers can also help ease symptoms of a cold or another respiratory condition. But be cautious — while humidifiers can be useful, they can actually make you sick if they aren't maintained properly or if humidity levels stay too high. If you do use humidifiers, play it safe: Monitor humidity levels and keep your humidifier clean — dirty humidifiers can breed mold or bacteria that can make you sick. If you have allergies or asthma, talk to your doctor before using a humidifier. . read more.

Children with Food Allergies Targeted by Bullies

More than 30 percent of children are reported to have been bullied, teased, or harassed because of their food allergy according to a study published this month. Although verbal abuse is the most common, over 40 percent were reported to have been threatened physically with acts such as being touched with their allergen or having the allergen thrown or waved at them. “Food allergies affect an estimated 12 million Americans, including 3 million children. These children face daily challenges in managing their food allergies,” said a co-author of the study. “Sadly, this study shows they may also be bullied about their food allergy, a medical condition that is potentially fatal.”. . read more.

Avoid the danger of anaphylaxis this Halloween

Ghosts and goblins aren’t the only scary things your children might encounter this Halloween. For parents of kids with food allergies, Halloween treats—from candy to cookies—can be frightening too. Common allergens such as peanuts, tree nuts, milk and egg are often ingredients in Halloween treats. Some kids may experience a rash or red, itchy skin, vomiting, a stuffy, itchy nose, or diarrhea or stomach cramps if they eat a food to which they are allergic. For children who are severely allergic, a single bite of these foods may cause a life-threatening reaction called anaphylaxis. . read more.

Have Asthma? Vitamin D May Help

Supplement your asthma action plan with Vitamin D and you may experience improved asthma control according to an article published this month in Annals of Allergy, Asthma & Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI).

Mold allergy: Manage this common condition

If you have a mold allergy, your immune system overreacts when you breathe in mold spores. This reaction triggers a cascade of reactions that lead to allergy symptoms. Like other allergies, a mold allergy can make you cough, make your eyes itch and cause other symptoms that make you miserable. In some people, mold allergy is linked to asthma and exposure causes restricted breathing and other airway symptoms. If you have a mold allergy, the best defense is to reduce your exposure to the types of mold that cause your reaction. While it isn't always possible to avoid mold allergy triggers, medications can help keep mold allergy reactions under control. . read more.

Allergies and asthma: They often occur together

You may wonder what allergies and asthma have in common besides making you miserable. A lot, as it turns out. Allergies and asthma often occur together. The same substances that trigger your hay fever symptoms may also cause asthma signs and symptoms such as shortness of breath, wheezing and chest tightness. This is called allergic asthma or allergy-induced asthma. Substances such as pollen, dust mites and pet dander are common triggers. In some people, skin or food allergies can cause asthma symptoms. . read more.

Smoking Ban Improves Asthma Rates in Children

In March 2006, Scotland banned smoking in enclosed public places, including restaurants and pubs. Investigators used a national database to tally all asthma hospital admissions for children younger than 15 years in Scotland between January 2000 and October 2009. Asthma hospital admission rates in children have dropped 18% per year since the smoking ban was instituted in 2006. . read more.

Do healthy children need flu shots?

The Centers for Disease Control and Prevention (CDC) recommends a yearly flu (influenza) vaccine for all children ages 6 months to 18 years — ideally given in September or as soon as the vaccine is available. The flu vaccine is available in two forms, flu shots which can be given to children age 6 months and older and a nasal spray (FluMist) which can be given to children age 2 years and older. Whether you choose a shot or nasal spray, keep in mind that children age 8 and younger who are receiving the flu vaccine for the first time or who didn't receive at least one dose of the 2009 H1N1 flu (swine flu) vaccine last year need two doses of this year's flu vaccine given at least four weeks apart. One dose is adequate for children age 9 and older and younger children who've been vaccinated before. . read more.

Allergy to Dogs (and Cats and Dust Mites) May Worsen Ragweed’s Impact

Ragweed allergy season can be even more miserable for those with dog, cat or dust mite allergies, according to new research. These year-round allergies appear to “pre-prime” the immune system so symptoms hit harder. Hay fever (known as seasonal allergic rhinitis) begins around the middle of August, when ragweed blooms. The typical symptoms – sneezing, itching, stuffy nose and watery eyes – can make sufferers miserable. Hay fever sufferers who also are allergic to cats, dogs or dust mites develop symptoms faster and (early on) more severely, the research suggests. Treating the cat, dog or dust mite allergy year round may help make the hay fever more manageable. “People with hay fever react differently when ragweed allergy season arrives. Some start sneezing right away, and others don’t, so we wanted to determine what makes certain people develop symptoms more quickly,” said the lead author of the study. . read more.

Why are my asthma symptoms worse when I have a cold?

In both children and adults, infections with cold viruses are the leading cause of worsening symptoms and loss of control of asthma. One particular cold virus, the Rhinovirus, is most frequently associated with increased asthma severity. Within the past few years, two studies reported the same unexpected finding: Rhinovirus infections with wheezing in infants and young children are associated with a significantly greater risk for developing childhood asthma, especially in children who are prone to allergic disease. These findings should help to identify events that initiate and worsen asthma and aid the development of therapies and perhaps even strategies for the prevention of asthma, which is the ultimate goal of asthma research. However, a more immediate question is how can these advances in knowledge be used today? . read more.

Products Act as a Screen To Protect Against Pollen

As if spring and summer weren't bad enough, fall brings with it yet another onslaught of misery to allergy sufferers. A growing category of natural therapies called pollen blockers work by stopping allergens from getting into your nose and lungs, say companies that sell them. A few well-designed studies have found pollen blockers effective, and allergists say they are likely to at least make a dent in a person's suffering. . read more.

Battling Pet Allergies

Almost 70% of U.S. households have domestic pets, equally divided between cats and dogs - that's 100 million pets!

A pet's dander, skin flakes, saliva and urine can cause an allergic reaction in some people. . read more.

Asthma: The age at onset may lie in one's genes

Previous studies have focused on whether or not someone gets asthma rather than on whether genetic factors influence the age at onset of the disease. Using a large population of twins, researchers have shown that genetic makeup causes different individuals to develop asthma at different ages. The idea of a genetic component interacting with different environmental triggers at different ages opens the possibility of modifying the course of the disease through identification of these determinants. . read more.

FDA, Vaccine Manufacturers: No Worries of Salmonella From Flu Vaccines

This year’s flu vaccine has some consumers worried. While it might protect them against a potentially deadly virus, could they end up with salmonella instead? The answer is no, according to the Food and Drug Administration and vaccine manufacturers. Flu vaccine is manufactured by growing virus in chicken eggs, and eggs are the source of a salmonella outbreak this summer that has been linked to nearly 1,470 illnesses and prompted a nationwide recall of more than 550 million eggs. But the eggs used to make flu vaccine come from different farms than those sold to consumers as food. Considered an important part of the government’s arsenal against a flu pandemic, they’re also tested vigorously for pathogens, officials say. Eggs used for vaccines are also fertilized, while those sold for eating are not. A “seed virus” is injected into eggs, which grows in the egg white and is later harvested for use in vaccine. . read more.

Medical Bracelets Go High-Tech. Style Aside, More People Find They Should Wear Them

It's a simple step, but one many doctors forget to remind patients to take: Wear a medical-alert bracelet. A growing number of American adults and children face complex medical conditions. . .

The Claim: Dark Cats Cause More Allergies Than Light Ones

THE FACTS: Cats, love them or hate them, are among the most common causes of allergies, affecting twice as many Americans as dogs do. The sources of these allergies are proteins found in feline dander, urine and saliva, making all cats capable of provoking reactions. But some scientists suspect that the darker a cat’s coat, the greater the likelihood of it inducing allergic reactions. . read more.

Risks: A Warning on Asthma and Acetaminophen

Young teenagers who use acetaminophen even once a month develop asthma symptoms more than twice as often as those who never take it, a large international study has found. And frequent users also had more eczema and eye and sinus irritation. Other studies have linked acetaminophen (often sold as Tylenol and in other over-the-counter remedies for pain, colds and fever) with an increased risk of asthma. But the new study’s authors cautioned that the findings did not mean children should stop using it. “Acetaminophen remains the preferred drug to relieve pain and fever in children,” said the study’s lead author. . read more.

Beware When the Label Says "Made in a Facility That Processes..."

While patients might be tempted to ignore food labels that say "made in a facility that processes" (something they're allergic to), new research suggests products with these labels are in fact more likely to be contaminated with peanuts, milk or eggs than unlabeled foods. "Our study underscores the need for allergic consumers to avoid advisory-labeled products, which present a small but real risk," the authors write in the study, which was reported online July 12th in a letter to the editor in the Journal of Allergy and Clinical Immunology. While companies are required to clearly state if their products have possible allergens in the ingredient list, there are no particular regulations on whether they need to add statements such as "may contain traces of peanuts," for example, for foods that aren't supposed to contain such allergens. . read more.

Be Aware of Epinephrine Autoinjector Substitution

An epinephrine autoinjector is used to treat a severe allergic reaction or to prevent anaphylactic shock caused by stinging insects, foods, latex, medications or other allergens. If you have a severe allergy and carry epinephrine, it is important to know that each brand functions a little differently. The stress of an anaphylactic reaction is not the time to realize you have a different autoinjector than what was demonstrated to you by your allergist. . read more.

Can I be allergic to my sunscreen?

With depletion of our ozone layer comes an increase in the amount of ultraviolet light that reaches us, and specifically our skin (the body’s largest organ). We need to be careful and practice careful and a limited exposure to sunlight to prevent aging of the skin as well as skin damage and skin cancers. Allergic contact dermatitis is responsible for a variety of skin reactions to sunscreens as well as a variety of other products such as cosmetics. In general, females are slightly more commonly affected than males, and adolescents and mid age adult appear to be more commonly affected. . read more.

In the Works: Immunotherapy for Food Allergies

From the time she was 11 months old until this past spring, Caroline Cooper was severely allergic to milk — a bit of cheese or yogurt could have killed her. But early last year, the teenager began a type of immunotherapy, eating minute but gradually increasing amounts of milk protein. But many allergists say immunotherapy for food allergies outside of a research setting is irresponsible. About 20 such trials are now underway, according to the National Institute of Health database and that's where such treatment should currently stay, these allergists say. . read more.

Damp House Linked to Kids' Risk of Nasal Allergies

Children who live in damp, water-damaged homes may be more likely to develop nasal allergies, a new study suggests. Researchers found that of nearly 1,900 children they followed for six years, those who lived in homes with dampness or mold problems were more likely to develop allergic rhinitis during the study period. In this study, published online July 16th in the American Journal of Epidemiology, 16% of children whose parents reported dampness in the home developed allergic rhinitis over the next six years. That compared with just under 12% of children whose parents reported no dampness problems -- that is, no visible signs of water damage to the ceilings, walls or floors, and no visible mold or mold odor in the home. The researchers weighed a number of factors that might help account for the connection, including families' socioeconomic status and whether children were also exposed to second-hand smoke. However, damp, moldy conditions in the home remained linked to an increased risk of children's nasal allergies. Children whose parents reported any mold or water damage in the home at the outset were 55% more likely than other children to develop allergic rhinitis -- connected to any allergen, not just mold. Such conditions encourage the growth of dust mites and fungi, and attract cockroaches -- all of which can serve as allergy triggers. Moisture may also boost the emission of chemicals from building materials, which could potentially create inflammation in the airways.

Nonallergic rhinitis

Nonallergic rhinitis involves chronic sneezing or having a congested, drippy nose with no apparent cause. The symptoms of nonallergic rhinitis are similar to those of hay fever (allergic rhinitis), but there's no allergic reaction involved. Nonallergic rhinitis can affect children and adults, but is more common after age 20. Although nonallergic rhinitis is more annoying than harmful, it can make you miserable. . read more.

Researchers Report Gene Linked to Asthma in Children

Researchers have found that a gene on chromosome one appears to be linked to moderate to severe persistent asthma in children -- the second such genetic locus associated with the disease. "In asthma, patients have an inappropriate immune response in which they develop airway inflammation and overreaction of the airway muscle cells, referred to as airway hyper-responsiveness," authors said. Gene mutations appear to lead to overproduction of immune system chemicals called cytokines that subsequently drive this oversensitive response in asthma patients. Authors said the research may have pinpointed a therapeutic target. "Because this gene seems to regulate many different cytokines, intervening in this pathway has great potential for treating asthma.”. . read more.

Sinus headaches

Sinus headaches are headaches that may accompany sinusitis, a condition in which the membranes lining your sinuses become swollen and inflamed. You may feel pressure around your eyes, cheeks and forehead. Perhaps your head throbs. Although these can indicate sinus headaches, don't jump to conclusions. Many people who assume they have sinus headaches actually have migraines or tension headaches. . read more.

If I have negative skin tests, does that mean I could not be allergic?

Allergists will typically use skin testing to find the presence or absence of an allergy. Skin testing can be done to allergens such as dust mites, cat, dogs, trees, etc as well as to foods, insect stings and, at times, antibiotics. Skin testing is done according to standard protocols typically using commercially prepared and monitored extracts. As with any test, it is possible that, even when done correctly, it may not be 100% accurate. . read more.

Getting the Facts on Food Allergy Testing

If you have ever experienced red, itchy skin, swelling, vomiting or trouble breathing after eating or coming into contact with a certain food, you may wonder if you have a food allergy.

Can consumers trust allergen advisory labels on food products?

For people with food allergies, shopping for safe foods to insure effective avoidance can be very confusing. Packaged foods often have labels advising of possible allergen contaminants, using wording like “may contain” or “made in a facility that processes”. This labeling, though, is voluntary and not standardized or regulated. Surveys suggest that food-allergic consumers appear to be increasingly ignoring these warnings, presumably out of frustration and doubt about whether the information can be trusted. . read more.

Summer Means Barbecues, Picnics — and Food Allergies

Ants, bees and rain aren't the only things that can put a damper on a picnic or barbecue.

Pet ownership is good for the soul, but is it good for the immune system?

Parents frequently ask physicians whether they should allow their children to have a household dog or cat because they worry that the exposure can cause allergies. So far, research findings on this question have been mixed. No study has taken a comprehensive look at the combined factors that could influence the answer, i.e., time, length and type of exposure, how long any protective effects might last, and the results of clinical tests that could confirm allergic sensitization. . read more.

Food allergy versus food intolerance

Some of the symptoms of food intolerance and food allergy are similar, but the differences between the two are very important. Eating a food you are intolerant to can leave you feeling miserable. However, if you have a true food allergy, your body’s reaction to this food could be life-threatening. A food intolerance response takes place in the digestive system. It occurs when you are unable to properly breakdown the food. An allergic reaction involves the immune system. Your im- mune system controls how your body defends itself. . read more.

Probiotics in Pregnancy Reduce Eczema in Infants

Mothers who take a probiotic supplement at the end of pregnancy and during breast-feeding may reduce the risk of atopic dermatitis in their infants, but the supplements had no effect on asthma, allergic rhinoconjunctivitis or atopic sensitization. About 65% of patients with atopic dermatitis develop it in infancy. An estimated 10-20% of infants and young children have symptoms of the disease. In multiple trials of probiotics given to infants, effects on allergic diseases varied greatly. Two trials reported last year, in which both the pregnant mothers and their infants were treated, suggested that probiotics reduced eczema in the children. . read more.

Exercise-Induced Bronchoconstriction (EIB) - Take Our EIB Quiz

Exercise-Induced Bronchoconstriction (EIB) is a narrowing of the airways causing difficulty moving air out of the lungs. Chronic asthma is an inflammatory disorder. Most patients with chronic asthma will have a flare when they exercise. Other individuals appear to have a flare of asthma only when they exercise and do not otherwise have chronic asthma. Symptoms include coughing, wheezing, tight chest, and prolonged and unexpected shortness of breath after about 6 to 8 minutes of exercise. These symptoms are often even worse in cold, dry air. Warm and humid air may lessen the symptoms. Unfortunately pollens and molds are present at the times of the year when the air is warm and humid and these substances in the air may also trigger attacks of asthma. . read more and take the EIB Quiz.

Dermatographia: When Scratching Your Skin Leaves its Mark

Dermatographia is a condition in which lightly scratching your skin causes raised, red lines where you've scratched. It's not serious, but it can be uncomfortable. In dermatographia, your skin cells are overly sensitive to minor injury, such as scratching or pressing on your skin. Signs and symptoms of dermatographia include redness, itching and swelling similar to hives. In most cases, dermatographia symptoms go away in a short time without treatment. But if symptoms are severe or bothersome, your doctor may suggest taking antihistamines. Simple self-care measures also can help you manage dermatographia. . read more.

Allergic Asthma May Diminish Healthy Immune Response to Respiratory Viruses

Allergic asthma may diminish the immune response to respiratory viruses such as influenza, according to new research findings in the June 1 issue of the Journal of Immunology. "Our findings imply that the better your asthma is controlled, the more likely you are to have an appropriate response to a virus," noted the author in a written release. He also reported that these findings suggest that when the cold/influenza and allergy seasons collide, the immune response in individuals with allergic asthma may worsen their disease. "These findings [may] imply that allergic triggers associated with exposure to indoor allergens like pet dander and dust mites can potentially render cells deficient in responding to a virus," she said. They also explain why people with allergic asthma may experience asthma exacerbations when they acquire respiratory viral infections. . read more.

Asthma medications: Know your options

Asthma medications play an important role in managing signs and symptoms such as coughing, wheezing and shortness of breath. Long-term control medications keep your symptoms at bay on a day-to-day basis. Quick-relief (rescue) medications treat asthma symptoms once they start. If your asthma is triggered by allergies, you may need to take allergy medications along with asthma medications to help control your symptoms. . read more.

Work Stress Linked to Higher Asthma Risk

People who regularly feel stressed out by their jobs may have a higher risk of developing asthma than those with a more-relaxed work atmosphere, a new study suggests. The new findings, published online April 27th in Allergy, are the first to show an association between work stress and later asthma risk, according to the researchers. The investigators found that among more than 5,100 adults they followed for nearly a decade, those who reported high job stress at the outset were twice as likely as those with low levels of work stress to develop asthma. . read more.

Asthma Improvements Do Not Persist When Long-Term Therapy Is Stopped

Findings published in the May Journal of Pediatrics suggest that improvements in asthma control and airway responsiveness achieved during long-term treatment with budesonide or nedocromil do not persist when treatment is discontinued.

Peanut Allergies on the Rise

The prevalence of peanut allergy among children tripled between 1997 and 2008, researchers found. Respondents to a telephone survey reported that 1.4% of children had peanut allergies, up from just 0.4% a decade earlier, Scott Sicherer, MD, of Mount Sinai School of Medicine in New York City, and colleagues reported in the May 12 issue of the Journal of Allergy and Clinical Immunology. "Although the total population prevalence of self-reported peanut and/or tree nut allergy did not increase among adults since 1997, there was a significant rise in self-reported allergies among children," the researchers wrote. . read more.

Burger and Fries Worsen Asthma, Study Suggests

A burger and fries are not only bad for the waistline, they might also exacerbate asthma, a new study suggests. Patients with asthma who ate a high-fat meal had increased inflammation in their airways soon afterward, and did not respond as well to treatment as those who ate a low-fat meal, the researchers found. The results provide more evidence that environmental factors, such as diet, can influence the development of asthma, which has increased dramatically in recent years in westernized countries where high-fat diets are common. In 2007, about 34.1 million Americans had asthma, according to the American Academy of Allergy, Asthma and Immunology. From 1980 through 1994, the prevalence of asthma increased 75 percent. While the results are preliminary, they suggest cutting down on fat might be one way to help control asthma. . read more.

Room for Debate: A Running Commentary on the News - The Squishy Science of Food Allergies

A federal report released last week found that while many more children and adults are reporting food allergies, no clear agreement exists on what a food allergy is or how to test for one. An article in Pediatrics in November 2009, for example, indicated that doctor visits for food allergies among children tripled from 1993 to 2006. What accounts for this increase in reported incidence of allergies: doctors making overly broad diagnoses, unreliable tests or anxious parents? What are some reasons or theories why more people now appear to be affected than in the past?. . read more.

I Can’t Eat That. I’m Allergic.

Allergen Immunotherapy Demonstrates Cost Savings among Children with Allergic Rhinitis - Significant Savings Seen within Three Months

In a recent study, authors examined Florida Medicaid data to compare health services use and costs between nearly 3,000 children newly diagnosed with allergic rhinitis (AR) who received allergen immunotherapy (IT) to a matched group of approximately 11,000 children with AR who did not receive IT. At 18 months, children with AR who received IT had one third lower total median health care costs than children with AR who did not receive IT, $3,247 versus $4,872. Outpatient costs were 58% lower and pharmacy costs were 16% lower for children who received versus did not receive IT. These significant health care savings were evident as early as 3 months following IT initiation, and increased throughout the study period. "This is great news, not only for families who will experience fewer out-of-pocket expenses for allergy medications, but also for the ever increasing national health care crisis " . . read more.

Time In Chlorinated Pools Ups Teens’ Asthma Risk

Teenagers who spent more than 1,000 hours swimming in chlorinated pools had more than eight times the asthma risk than subjects who swam in copper-silver disinfected pools, according to a study in Pediatrics. Scientists enrolled 847 subjects from 13 to 18 years old who had visited indoor or outdoor swimming pools. Of the 847, 114 mainly visited copper-silver disinfected pools; 733 visited chlorine-disinfected pools. The number of subjects who had ever had asthma increased in proportion to their chlorine-disinfected pool exposure. And risk of current asthma was more than eight times higher in the group with more than 1,000 hours in chlorine-disinfected pools compared with subjects who were rarely in chlorinated water. . read more.

Early Signs of Asthma But Parents Delay Treatment

According to Doctor Jane Garbutt, MBChB, parents of young asthmatic children, age 2-10 accurately recognized the onset of an attack of asthma, at least 80% of the time. They noted an increase in respiratory symptoms such as cough, shortness of breath, and wheeze along with non-specific changes including change in behavior, vomiting, and dark circles under the eyes. The early warning signs were usually the same with each exacerbation of asthma. The use of objective monitoring, e.g. measuring lung function using a peak flow meter or keeping a symptom diary was reported less than 25% of the time. However, even when recognizing these early signs and symptoms of asthma, parents often delayed increasing the intensity of the asthma treatment, at times until the child was gasping for breath or using accessory muscles for breathing. . read more.

Allergy medications and pregnancy: What's safe?

Is it safe to take Claritin or other allergy medications during pregnancy? Allergy medications are sometimes recommended during pregnancy. Before you take any medication during pregnancy, however, it's important to weigh the severity of your symptoms against the possible risks to your baby. Loratadine (Claritin, others) is considered a category B drug — which means that animal studies haven't shown any risks to unborn babies whose mothers take the drug. Still, category B drugs haven't been adequately tested during human pregnancy to offer any guarantees. Rather than depending on allergy medications, you might consider other ways to manage your allergy symptoms. . read more.

Excessive cleanliness may boost allergies

Children With Food-Related Anaphylaxis Need Access to 2 Epinephrine Injections

Keeping 2 doses of epinephrine on hand is recommended for children with life-threatening food allergies, according to a study published online March 22 in Pediatrics. Approximately 3 million children in the United States have food allergies, and that number is growing. Food allergies are the chief cause of anaphylaxis, a sometimes-fatal allergic response, which progresses quickly to constrict the airway, irritate the skin and intestines, and/or affect heart rhythm. The prevalence of food allergies in developed countries is currently nearly 6% and appears to be increasing. Recent studies also suggest a dramatic increase in the incidence of anaphylaxis, with food allergy shown to be the leading cause of anaphylaxis in children.Current practice guidelines recommend that all patients suspected of having an episode of food-related anaphylaxis be referred to an allergist, counseled to avoid the suspected food trigger, and prescribed self-injectable epinephrine. Prompt administration of epinephrine is the primary treatment of food-related anaphylaxis. It is recommended that children with a history of food-related anaphylaxis carry multiple doses of self-injectable epinephrine, although evidence supporting this practice is limited .. read more.
