Climate change a growing threat to human health, report


The US Global Change Research Program, a government agency,  released a new assessment of a the public health threat posed by climate change.

Here’s the summary of the report: The Impacts of Climate Change on Human Health in the United States –A Scientific Assessment:

Climate change is a significant threat to the health of the American people. The impacts of human-induced climate change are increasing nationwide. Rising greenhouse gas concentrations result in increases in temperature, changes in precipitation, increases in the frequency and intensity of some extreme weather events, and rising sea levels.


These climate change impacts endanger our health by affecting our food and water sources, the air we breathe, the weather we experience, and our interactions with the built and natural environments. As the climate continues to change, the risks to human health continue to grow. Continue reading

Benefits of peanut allergy prevention strategy persist after one-year peanut avoidance

From the National Institutes of Health

The benefits of regularly consuming peanut-containing foods early in life to prevent the development of peanut allergy persist even after stopping peanut consumption for one year, new clinical trial findings show.

The trial, called LEAP-On, was supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and conducted by the NIAID-funded Immune Tolerance Network (ITN). T

he results were published online March 4 in the New England Journal of Medicine and presented at the annual meeting of the American Academy of Allergy, Asthma and Immunology in Los Angeles.

The LEAP-On study is an extension of the Learning Early About Peanut Allergy (LEAP) study. LEAP showed that regular peanut consumption begun in infancy and continued until 5 years of age led to an 81 percent reduction in development of peanut allergy in infants deemed at high risk because they already had severe eczema, egg allergy or both.

At the end of LEAP, participants who enrolled in LEAP-On were instructed to avoid peanut consumption for one year to help investigators determine whether continuous peanut consumption is required to maintain protection against development of peanut allergy.

After the avoidance period, peanut allergy prevalence was determined, as it was in LEAP, by an oral food challenge. Only 4.8 percent of the children who had regularly consumed peanut-containing foods during LEAP were allergic to peanut following the year of peanut avoidance.

In comparison, the prevalence of peanut allergy was 18.6 percent among those who had avoided peanut throughout LEAP and LEAP-On. Continue reading


Hay Fever: Symptoms, causes, prevention and treatment



By David Jeong, MD
Virginia Mason University Village Medical Center

Although many think of spring as the time of year when most people are bothered by allergic rhinitis, or hay fever, the condition can affect folks year round depending on what an individual is allergic to at any given time. In fact, as an allergist, I see children and adults with allergic rhinitis all 12 months of the year.

What is Hay Fever?

Hay fever is the group of uncomfortable symptoms that occur when your body is exposed to a specific allergen. An allergen is a typically harmless substance that causes an allergic reaction.

When your body comes into contact with an allergen, the immune system recognizes it and signals the release of histamine, among other natural chemicals, from the body. Unfortunately, an excess of histamine can cause uncomfortable symptoms.

As a result, it is important to seek treatment since this condition can interfere with your everyday quality of life.

Types of allergens 

Common allergens that can cause this condition include:

  • Grasses and weeds
  • Dust mites
  • Animal dander (old skin) and saliva
  • Mold
  • Pollens (Pollens are the biggest allergen culprit during certain seasons – trees during early and mid-spring, grasses during summer and weeds in fall)

Risk factors for allergic rhinitis 

Although allergies can affect anyone, they are often inherited. You are more likely to develop allergic rhinitis if your family has a history of allergies.

Other risk factors for developing hay fever include:

FDA warns consumers of the dangers of using homeopathic products to treat asthma


FDA warns consumers about the potential health risks of over-the-counter asthma products labeled as homeopathic

From the Food and Drug Administration

Illustration of the lungs in blueThe U.S. Food and Drug Administration is warning consumers not to rely on asthma products  labeled as homeopathic that are sold over-the-counter (OTC). These products have not been evaluated by the FDA for safety and effectiveness.

Asthma is a serious, chronic lung condition. If asthma is not appropriately treated and managed, patients may have wheezing, shortness of breath, and coughing, and could be at risk for life-threatening asthma attacks that may require emergency care or hospitalization.

Although there is no cure for asthma, there are many prescription asthma treatments approved by FDA as safe and effective, as well as some products that are marketed OTC in accordance with an FDA monograph.  Continue reading


Medications for allergies – an FDA Consumer Update


bee on flowerConsumer Update from the FDA

You’re sneezing, your eyes are itchy and you feel miserable. Seasonal allergies aren’t just a nuisance, they are real diseases that can interfere with work, school or recreation, and can range from mild to severe.

May is National Asthma and Allergy Awareness Month, and many allergy treatment options are approved by the Food and Drug Administration (FDA). For the first time, these include three sublingual (under the tongue) prescription products to treat hay fever (also called “allergic rhinitis”)—with or without eye inflammation (called “conjunctivitis”)—caused by certain grass pollens and short ragweed pollen.

The new products—GrastekOralair and Ragwitek—can be taken at home, but the first dose must be taken in a health care provider’s office.

Women’s Health – Week 3: Asthma


From the NIH Office of Research on Women’s Health

tacuin womenAsthma is a chronic (long-term) lung disease that inflames and narrows the bronchioles or airways. People of all ages have asthma, but it most often starts in childhood.

Asthma causes recurring periods of wheezing (a whistling sound when you breathe),  chest tightness,  shortness of breath,  and coughing. The coughing often occurs at night or early in the morning.

Many people with asthma are allergic to airborne allergens. It is believed that allergens (mostly those found indoors),  when inhaled, cause inflammation in the airways in the lungs. Inflamed airways are more sensitive to allergens,  but also extremely sensitive to irritants and to some viral infections.

Allergens,  irritants,  and viral infections can trigger asthma attacks. During an asthma attack,  the muscles surrounding the walls of the airways in the lungs constrict and narrow the airways.

Also, the inside walls of the airways become swollen, making the airways even narrower. The constricting and swelling of the airways prevent air from flowing freely through the lungs.

In a severe asthma attack,  the airways can close so much that not enough oxygen gets to vital organs like the heart and brain. These severe attacks are considered medical emergencies.

If your asthma is not well controlled, then you may miss school, work, and other activities.


A diagram of the lungs showing the difference between normal airways, or bronchioles, and asthmatic bronchioles.

Symptoms of asthma include:

  • Difficulty breathing.
  • Wheezing.
  • Coughing.
  • Tightness in the chest.

Even when you feel fine,  you still have the disease and it can flare up,  especially when you breathe in allergens or irritants from the environment. These are called triggers.

Some common asthma triggers include:

  • Allergens such as animal dander from the skin,  hair,  or feathers of animals;  dust mites (contained in house dust);  cockroaches;  pollen from trees and grass;  and mold (indoor and outdoor).
  • Airborne irritants including smoke,  strong odors or scents,  and pollution.
  • Cold air,  changes in weather,  and exercise.
  • Workplace chemicals or allergens.
Asthma and pregnancy
Pregnant women who have asthma need to control the disease to ensure their fetus gets enough oxygen. Poor asthma control raises the chance that a baby will be born early,  have a low birth weight,  and be at risk of death. Studies show that it is safer to take asthma medicines while pregnant than to risk having an asthma attack. But you need to carefully review these medicines with your health care provider.

Asthma cannot be cured. With proper treatment,  most people who have asthma can control their asthma and be active all day and sleep well at night. You can control your asthma with these key actions:

  • Work with your health care provider to make a written action plan that describes how you can manage your asthma day-to-day. Be sure to ask questions and discuss any concerns about your asthma treatment. This way,  you and your health care provider can work together on a plan that is best for you.
  • Take your medications as directed. Everyone with asthma needs a quick relief medication for symptoms. Many patients need daily long-term control medication. Most of these patients use inhaled corticosteroids,  but some may need additional medications.
  • Avoid or control allergens or irritants that make your asthma worse. Your health care provider will help you learn which triggers affect you the most and how to avoid or control them.
  • Get regular asthma checkups to monitor your asthma control and see if your treatment should stay the same or be changed. Visits at least every 6 months are recommended because asthma varies from season to season and can change over time (for example,  as a child grows older or if a woman is pregnant).

Women’s Health – Week 2: Allergies


tacuin womenFrom the NIH Office of Research on Women’s Health

You can develop allergies when your immune system overreacts to something in the environment,  either in the air or from another source.

These environmental substances are called allergens. Allergens that commonly cause allergic reactions can be divided into airborne and non-airborne. Examples of these include:


  • Pollens.
  • House dust mites.
  • Cat or dog dander and saliva.
  • Mold spores.
  • Cockroaches.


  • Food.
  • Latex rubber.
  • Insect venom.
  • Medicines (for example,  penicillin).

Your immune system usually functions as your body’s defense against bacteria and viruses. In an allergic reaction,  your immune system mistakes the allergen for an invader and sets up a response that mimics how your body attacks a bacteria or virus.

This section focuses on airborne allergens,  which are responsible for allergen-induced symptoms in the nose (allergic rhinitis),  eyes (allergic conjunctivitis),  and lungs (asthma).

Common signs and symptoms of allergic rhinitis and conjunctivitis caused by airborne allergens
  • Sneezing,  often with congestion and a runny nose.
  • Coughing and postnasal drip.
  • Itching eyes,  nose,  and throat.
  • Watering eyes.
  • Allergic shiners (dark circles under the eyes caused by increased congestion of blood vessels).

Allergic rhinitis and conjunctivitis can probably be treated with medicines. The kind of allergy medications you use will depend on the type of symptoms you have and how bad those symptoms are.

Medications you can use to treat allergic rhinitis and conjunctivitis include:

  • Antihistamines (either pills or nasal sprays – for nasal itching and runny nose).
  • Antihistamine eye drops (for eye itching and watery eyes).
  • Nasal corticosteroids (nasal sprays – for all nose symptoms).
  • Decongestants (either pills or nasal sprays – only for nasal congestion).
  • Immunotherapy (shots of allergens under the skin – for all nose and eye symptoms).
  • Allergies can lead to other more serious health problems,  including asthma.

FDA warns of rare acetaminophen risk


A Consumer Update from the US Food and Drug Administration

ucm363013Acetaminophen, a fever and pain reliever that is one of the most widely used medicines in the U.S., can cause rare but serious skin reactions, warns the Food and Drug Administration (FDA).

Although rare, possible reactions to acetaminophen include three serious skin diseases whose symptoms can include rash, blisters and, in the worst case, widespread damage to the surface of skin.

If you are taking acetaminophen and develop a rash or other skin reaction, stop taking the product immediately and seek medical attention right away.

Used for decades by millions of people, acetaminophen is the generic name of a common active ingredient included in numerous prescription and non-prescription medicines.

Tylenol is one brand name of the pain reliever sold over the counter, but acetaminophen is also available as a generic under various names.

It is also used in combination with other medicines, including opioids for pain and medicines to treat colds, coughs, allergy, headaches and trouble sleeping.

“This new information is not intended to worry consumers or health care professionals, nor is it meant to encourage them to choose other medications,” says Sharon Hertz, M.D., deputy director of FDA’s Division of Anesthesia, Analgesia and Addiction. “However, it is extremely important that people recognize and react quickly to the initial symptoms of these rare but serious, side effects, which are potentially fatal.”

Other drugs used to treat fever and pain, such as nonsteroidal anti-inflammatory drugs including ibuprofen and naproxen, already carry warnings about the risk of serious skin reactions.

Advil and Motrin are among the common brand names that include ibuprofen as an active ingredient. Aleve and Midol Extended Relief are among the best-known brand names that include naproxen as an active ingredient.

FDA is requiring that a warning about these skin reactions be added to the labels of all prescription medicines containing acetaminophen.

FDA will work with manufacturers to get the warnings added to the labels of over-the-counter (OTC) medicines containing acetaminophen.

On OTC medicines, the word “acetaminophen” appears on the front of the package and on the Drug Facts label’s “active ingredients” section.

On prescription medications, the label may spell out the ingredient or use a shortened version such as “APAP,” “acet,” “acetamin” or “acetaminoph.”

Ingredient Linked to Several Conditions

Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN) are the two most serious skin reactions linked in rare cases to acetaminophen. They usually require hospitalization and can cause death.

Problems usually begin with flu-like symptoms followed by rash, blistering and extensive damage to the surfaces of the skin. Recovery can take weeks or months, and possible complications include scarring, changes in skin pigmentation, blindness and damage to internal organs.

A third skin reaction, acute generalized exanthematous pustulosis (AGEP), usually resolves within two weeks of stopping the medication that caused the problem.

A serious skin reaction can occur at any time, even if you’ve taken acetaminophen previously without a problem. There is currently no way of predicting who might be at higher risk.

If you’ve ever had a skin reaction when taking acetaminophen, don’t take the drug again and discuss alternate pain relievers/fever reducers with your health care professional.

Evidence of Link

Prior to deciding to add a warning about skin reactions to products containing acetaminophen, FDA reviewed medical literature and its own database, the FDA Adverse Event Reporting System (FAERS).

A search of FAERS uncovered 107 cases from 1969 to 2012, resulting in 67 hospitalizations and 12 deaths. Most cases involved single-ingredient acetaminophen products; the cases were categorized as either probable or possible cases associated with acetaminophen.

A small number of cases, just over two dozen, are documented in medical literature, with cases involving people of various ages.

FDA has examined—and continues to examine—acetaminophen for safety issues, just as it does with all approved drugs. The warning comes two years after FDA took new steps to reduce the risk of liver injury from acetaminophen.

In that case, FDA asked all makers of prescription products to limit acetaminophen to 325 milligrams per tablet or capsule. FDA also required all prescription acetaminophen products to include a Boxed Warning—FDA’s strongest warning, used for calling attention to serious risks.

The agency continues to consider the benefits of this medication to outweigh the risks.

“FDA’s actions should be viewed within the context of the millions who, over generations, have benefited from acetaminophen,” says Hertz. “Nonetheless, given the severity of the risk, it is important for patients and health care providers to be aware of it.”

Had a bad reaction to a prescription drug? FDA wants to hear about it.


WANTED: Consumers to Report Problems

An FDA Consumer Update

Blue and white capsules spilling out of a pill bottle

new consumer-friendly form is now available for making reports to MedWatch, the Food and Drug Administration’s (FDA) on-line system for collecting information about serious problems with drugs, medical devices and other FDA-regulated products.

The less technical form is part of a larger effort to encourage consumers to submit quality reports.

By reporting your experience or suspicion of a product problem to MedWatch, you could help identify an unknown risk and potentially spark a variety of actions—from changes to a warning label to removal of the product from the market.

Use MedWatch to report issues with:

  • Prescription and over-the-counter drugs
  • Nutrition products, including infant formulas, dietary supplements, herbal remedies
  • Cosmetics
  • Medical devices, from contacts and breast implants to test kits and pacemakers
  • Biologics, such as human cells and tissues for transplantation and medicines made from living matter
  • Food (including beverages and ingredients added to foods)

Consumers have been welcome to report side effects, product quality problems and other issues to MedWatch since the program was founded in 1993, although the focus had always been more on encouraging reporting from health care professionals.

But as more and more consumers visit online sites to research their conditions and understand their care, opportunities for increasing their participation in MedWatch became clear. FDA asked consumer groups to help promote the website and the MedWatch reporting form to their members.

“Their initial response was that the reporting form was too technical, and they suggested a more consumer-friendly version,” said Beth Fritsch, R.Ph., MBA, deputy director of FDA’s Office of Health and Constituent Affairs.

Working with groups such as AARP, Consumers Union and the National Partnership for Women and Families, FDA created a new form and published it for public comment in the Federal Register. Those comments were also considered, further revisions were made, and the less technical form is now available at MedWatch.

To spread awareness of the reporting mechanism, FDA is using social media, including Twitter, email lists and electronic newsletters. It is also getting help in this effort from librarians, consumer organizations, patient advocacy groups, health professional organizations and schools of medicine, pharmacy and nursing.

Additionally, MedWatchLearn, a new web-based learning tool, will be used to teach students in medical, pharmacy and nursing schools to fill out MedWatch reports and encourage others to do so.

How Your Reports Could Help

Even though consumers have been less likely than health care professionals to report problems to MedWatch, their cooperation to date has already been beneficial. For example, consumer reports to MedWatch led to a nationwide recall of a particular lot of pre-filled syringes.

Consumer reports also alerted FDA to an unusual issue: Men using a testosterone gel on their upper arms and shoulders were inadvertently exposing, and harming, children. The reports led to stronger product warning labels to alert the public and urge that the gel be covered after application so it wouldn’t get on other people.

“MedWatch is one of the lines of defense against products that are contaminated or that pose risks that weren’t previously known,” said Anna Fine, Pharm.D., director of FDA’s Health Professional Liaison Program. “Greater consumer involvement will mean we have more eyes and ears available to catch problems before they escalate.”

MedWatch reports sometimes provide the first clue that an issue needs investigation and possible action. In other cases, a clinician or researcher inside or outside FDA might first suspect a link between a problem and a drug or other product, and MedWatch becomes a useful database that FDA experts can search for additional clues.

Consumers can play a particularly critical role by reporting unexpected, serious side effects from medicines given to children. Most clinical trials for children’s medicines involve a relatively small number of patients, and problems might not be detected until medicines have been used by a large number of children of different ages.

How To Report

Consumers can continue to ask their health care professional to file a MedWatch report or to report a suspected problem directly to a drug manufacturer.

By law, companies are required to report to FDA certain serious problems that may have been caused by their products, including in cases where consumers report suspected problems to the company. Currently, the vast majority of more than 900,000 MedWatch reports a year are funneled to FDA through companies.

However, consumers who decide to report a problem directly to FDA themselves will find that the new form is now easier and quicker to fill out.

“There is a delicate balance between asking for useful, scientific data and encouraging participation by making the form accessible to consumers,” said Fritsch. “We’ve made a great effort to find that balance.”

Consumers are not expected to provide proof that the problem was caused by the particular product. And Fritsch adds that consumers should send the report even if they don’t have all the information requested. Questions are answered at MedWatch’s toll-free line, 1-800-332-1088, between 8 a.m. and 4:30 p.m. ET.

MedWatch forms for both consumers and health care professionals must be faxed or mailed. Online submission capability will be available in coming months.

Fritsch, who noted that MedWatch is marking its 20th anniversary, concluded: “Every report counts.”

How to control your seasonal allergies


From NIH Medline Plus magazine

Trusted information from the National Institutes of Health



Allergic reactions occur when the body wrongly defends itself against something that is not dangerous. A healthy immune system defends against invading bacteria and viruses. During allergic reactions, however, the immune system fights harmless materials, such as pollen or mold, with production of a special class of antibody called immunoglobulin E (IgE).

Plant Pollen

Ragweed and other weeds, such as curly dock, lambs quarters, pigweed, plantain, sheep sorrel, and sagebrush are prolific producers of pollen allergens. Ragweed season runs from August to November, but pollen levels usually peak by mid-September in many areas in the country. Pollen counts are highest in the morning, and on dry, hot, windy days.

Protecting Yourself

  • Between 5:00 and 10:00 in the morning, stay indoors. Save outside activities for late afternoon or after a heavy rain, when pollen levels are lower.
  • Keep windows in your home and car closed to lower exposure to pollen. Keep cool with air conditioners. Don’t use window or attic fans.
  • Use a dryer, not a line outside; dry your clothes and avoid collecting pollen on them.

Grass Pollen

Grass pollens are regional as well as seasonal. Their levels also are affected by temperature, time of day, and rain. Only a small percentage of North America’s 1,200 grass species cause allergies, including:

  • Bermuda grass
  • Johnson grass
  • Kentucky bluegrass
  • Sweet vernal grass
  • Timothy grass
  • Orchard grass

Protecting Yourself

  • Between 5:00 and 10:00 a.m., stay indoors. Save outside activities for late afternoon or after a heavy rain, when pollen levels are lower.
  • Keep windows in your home and car closed to lower exposure to pollen. Keep cool with air conditioners. Don’t use window or attic fans.
  • Use a clothes dryer, not a line outside, to avoid collecting pollen on them.
  • Have someone else mow your lawn. If you mow, wear a mask.

Tree Pollen

Trees produce pollen earliest, as soon as January in the south, and as late as May and June in the northeast. They release huge amounts that can be distributed miles away. Fewer than 100 kinds of trees cause allergies. The most common tree allergy is against oak, but others include catalpa, elm, hickory, sycamore, and walnut.

Protecting Yourself

  • Follow the same protective strategies related to time of day, closed windows, and clothes dryers noted in “Protecting yourself” under Grass Pollen, above.
  • Plant species that do not aggravate allergies, such as crape myrtle, dogwood, fig, fir, palm, pear, plum, redbud, and redwood trees, or the female cultivars of ash, box elder, cottonwood, maple, palm, poplar, or willow trees.

Seasonal Allergies: Nuisance or Real Health Threat?

For most people, hay fever is a seasonal problem—something to endure for a few weeks once or twice a year. But for others, such allergies can lead to more serious complications, including sinusitis and asthma.

  • Sinusitis is one of the most commonly reported chronic diseases and costs almost $6 billion a year to manage. It is caused by inflammation or infection of the four pairs of cavities behind the nose. Congestion in them can lead to pressure and pain over the eyes, around the nose, or in the cheeks just above the teeth. Chronic sinusitis is associated with persistent inflammation and is often difficult to treat. Extended bouts of hay fever can increase the likelihood of chronic sinusitis. But only half of all people with chronic sinusitis have allergies.
  • Asthma is a lung disease that narrows or blocks the airways. This causes wheezing, shortness of breath, coughing, and other breathing difficulties. Asthma attacks can be triggered by viral infections, cold air, exercise, anxiety, allergens, and other factors. Almost 80 percent of people with asthma have allergies, but we do not know to what extent the allergies trigger the breathing problems. However, some people are diagnosed with allergic asthma because the problem is set off primarily by an immune response to one or more specific allergens. Most of the time, the culprit allergens are those found indoors, such as pets, house dust mites, cockroaches, and mold. Increased pollen and mold levels have also been associated with worsening asthma.


Testing for Allergies

Knowing exactly what you are allergic to can help you lessen or prevent exposure and treat your reactions. There are several tests to pinpoint allergies:

  • Allergy skin tests—Allergy skin testing is considered the most sensitive testing method and provides rapid results. The most common test is the “prick test,” which involves pricking the skin with the extract of a specific allergen, then observing the skin’s reaction.
  • Serum-specific IgE antibody testing—These blood tests provide information similar to allergy skin testing.


For allergy sufferers, the best treatment is to avoid the offending allergens altogether. This may be possible if the allergen is a specific food, like peanuts, which can be cut out of the diet, but not when the very air we breathe is loaded with allergens, such as ragweed pollen. Various over-the-counter or prescription medications can relieve symptoms.

  • Antihistamines. These medications counter the effects of histamine, the substance that makes eyes water and noses itch and causes sneezing during allergic reactions. Sleepiness was a problem with the oldest antihistamines, but the newest drugs do not cause such a problem.
  • Nasal steroids. These anti-inflammatory sprays help decrease inflammation, swelling, and mucus production. They work well alone and, for some people, in combination with antihistamines; in recommended doses, they are relatively free of side effects.
  • Cromolyn sodium. A nasal spray, cromolyn sodium can help stop hay fever, perhaps by blocking release of histamine and other symptom-producing chemicals. It has few side effects.
  • Decongestants. Available in capsule and spray form, decongestants may reduce swelling and sinus discomfort. Intended for short-term use, they are usually used in combination with antihistamines. Long-term usage of spray decongestants can actually make symptoms worse, while decongestant pills do not have this problem.
  • Immunotherapy. Immunotherapy (allergy shots) might provide relief for patients who don’t find relief with antihistamines or nasal steroids. Allergy shots alter the body’s immune response to allergens, thereby helping to prevent allergic reactions. They are the only form of treatment that can induce long-lasting protection for several years after therapy is stopped. Current immunotherapy treatments are limited because of potential allergic reactions; rarely, these can be severe.

Seasonal Allergy Research at NIH

  • Asthma and Allergic Diseases Cooperative Research Centers: In 1971, the National Institute of Allergy and Infectious Diseases (NIAID) established its Asthma and Allergic Diseases Centers to conduct basic and clinical research on the mechanisms, diagnosis, treatment, and prevention of asthma and allergic diseases.
  • Immune Tolerance Network (ITN): The ITN is an international consortium of investigators in the United States, Canada, Europe, and Australia dedicated to the development and evaluation of novel, tolerance-inducing therapies in such disorders as asthma and allergic rhinitis.
  • Inner-City Asthma Consortium: Since 1991, the NIAID has funded research on asthma in inner-city areas with the goal of improving the treatment of children living in environments where the prevalence and severity of asthma is particularly high.
  • Allergen Epitope Research and Validation Centers: The goal of this NIAID program is to identify the portions of allergy-inducing molecules that immune system cells and IgE antibodies recognize, and to develop therapies that block these portions from causing allergic reactions.

CDC’s new antismoking campaign: Tips from Former Smokers


This week the US Centers for Disease Control and Prevention (CDC) launches a new ad campaign featuring the stories of former smokers living with smoking-related diseases and disabilities.

“Tips from Former Smokers” ads will run for at least 12 weeks on television, radio, and billboards, online, and in theaters, magazines, and newspapers nationwide.

The education campaign seeks to provide motivation, information, and quit help to those who want it, CDC officials said.

  • The ads feature smoking-related health conditions— including chronic obstructive pulmonary disease or COPD, more severe adult asthma, and complications from diabetes, such as blindness, kidney failure, heart disease, and amputation—and candidly describe the losses from smoking and the gains from quitting
  • Despite the known dangers of tobacco use, nearly one in five adults in the United States still smoke.  Almost 90 percent of smokers started before they were 18, and many of them experience life-changing health effects at a relatively early age. Smoking harms nearly every organ in the body.
  • More than 440,000 Americans each year lose their lives to smoking-related diseases, and for every one death 20 more continue living with one or more serious illnesses from smoking.  Nearly 70 percent of smokers say they want to quit.

What you need to know about gluten and celiac disease


By Lola O’Rourke, MS, RD
Valley Medical Center 

Celiac Disease (CD) is the result of an immune system response to the ingestion of gluten, a protein found in wheat, rye and barley.

When people with CD ingest gluten, this auto-immune response causes damage to the small intestine, reducing the body’s ability to absorb nutrients, leading to many of the most common symptoms of CD.

If left untreated, CD can have serious long term health consequences.

The symptoms of CD are extremely varied, and mirror symptoms for other conditions too. This is, in part, why it often takes a long time for CD to be diagnosed – the average length of time it takes for a diagnosis is about four years.

To complicate matters, many people with CD do not have obvious symptoms at all – they may have anemia or low bone density, conditions which may present during a routine medical exam.

Some of the most common symptoms include diarrhea, constipation, bloating, weight loss, anemia, chronic fatigue, infertility, migraines, bone pain and muscle cramps.

It’s estimated that about 1 percent of the U.S. population has Celiac Disease; the vast majority of these cases are undiagnosed. To develop CD, it’s necessary to have a genetic predisposition, to be consuming gluten and to have the disease activated by a triggering event such as surgery, illness, or even stress.

The first step to diagnosing CD is a blood test ordered by your physician which will look for the presence of antibodies that are indicative of CD. If these tests suggest CD, a biopsy of the small intestine is recommended to determine if the intestinal cells show damage consistent with this condition.

The biopsy is considered the “gold standard” for a CD diagnosis. If the biopsy does indicate CD, a gluten-free diet is warranted. Part two of the “gold standard” CD diagnosis is if the patient experiences improvement on a gluten-free diet.

People who experience adverse reactions to gluten but test negative for celiac disease may have a condition called non-celiac gluten sensitivity (NCGS). Symptoms tend to overlap with those of CD, however, in the case of NCGS an intestinal biopsy would be negative.

Treatment for NCGS is also a gluten-free diet. The recognition and classification of NCGS is quite new and more research is needed, but estimates claim the incidence of NCGS is up to 6 or 7 times higher than that of CD.

The “good” news about CD (and NCGS) compared with many other medical conditions is that it can be treated by diet. (Note: In some cases, especially the newly diagnosed, nutritional supplements and/or other medications may be required to treat related conditions: consult with your primary care physician and dietitian.)

What’s sometimes viewed as “bad” news (often for the newly diagnosed) is that it MUST be treated by diet. The only known treatment is a strict gluten-free diet. Although a gluten-free diet may seem restrictive at first, you can still enjoy a wide range of delicious foods, and in time, it will seem second nature.

There is a wealth of good information available to help people live a healthy and satisfying gluten-free life. The Gluten Intolerance Group (GIG) is a non-profit organization that provides an extensive range of educational information on numerous aspects of celiac disease and other gluten-related disorders, including how to eat safely in restaurants, what to do about gluten in medications, and how to use gluten-free grains.

Visit for information, recipes and listings of certified gluten-free products. GIG also has a network of support groups around the country.

Getting involved with a support group can be very helpful in terms of learning about local gluten-free resources (grocery stores, products, restaurants), as well as for sharing stories and getting support, especially during the early stages of learning about the gluten-free diet.

Hope for beating egg allergy


From NIH Research Matters

Giving small daily doses of egg powder to children with egg allergy could pave the way to letting them eat the food safely, a new study finds.

This would make life easier on kids whose only current option is to stay away from all foods that contain eggs.

Egg allergy is one of the most common food allergies in children. There’s no treatment other than completely avoiding the food.

That’s tough for children, parents and caregivers; eggs can lurk in everything from marshmallows to salad dressing.

And the stakes are high. Children who are allergic to eggs can have reactions ranging from hives to anaphylaxis, a life-threatening condition with symptoms that include throat swelling, a sudden drop in blood pressure, trouble breathing and dizziness.

One possible way to help people with food allergies is oral immunotherapy.

In this still-experimental approach, patients eat gradually increasing amounts of the food they’re allergic to. A research team led by Dr. A. Wesley Burks at the University of North Carolina and Dr. Stacie M. Jones at the University of Arkansas for Medical Sciences tested oral immunotherapy for children who are allergic to eggs.

The study was funded by NIH’s National Institute of Allergy and Infectious Disease (NIAID), National Center for Research Resources (NCRR) and the National Center for Advancing Translational Sciences (NCATS).

The researchers recruited 55 children, ages 5 to 18, who were allergic to eggs. Forty of the participants ate daily doses of raw egg-white powder. The others received cornstarch as a placebo.

Researchers increased the dose every 2 weeks until the children on oral immunotherapy were eating the equivalent of about one-third of an egg every day.

At 10 months, the participants went into the clinic, where they were “challenged” with increasing doses of egg-white powder and watched closely for symptoms.

As reported in the July 19, 2012, issue of the New England Journal of Medicine, more than half of the children who had been eating egg powder daily passed the challenge, with no allergic reaction or only minor symptoms.

ral food challenges should not be tried at home because of the risk of severe allergic reactions.”A year later, 30 children passed a challenge with an even larger dose of egg powder. In contrast, none of the children in the placebo group passed the challenge.

Those 30 children stopped oral immunotherapy and were told to avoid all eggs for 4 to 6 weeks. Then they faced another challenge: a dose of egg powder and a whole cooked egg.

Most kids had allergic reactions, but 11 passed the test and were allowed to eat as many eggs or egg-containing foods as they wanted in their normal diets. A year later, those children reported they still had no problems eating eggs.

The study suggests 2 ways that egg oral immunotherapy could help children. First, while they were eating the daily dose of egg powder, most of the children could safely eat eggs. Second, a small group of children—about 1 in 4—were able to eat eggs even after the daily oral immunotherapy ended.

“Although these results indicate that oral immunotherapy may help resolve certain food allergies, this type of therapy is still in its early experimental stages and more research is needed,” says Dr. Daniel Rotrosen, director of NIAID’s Division of Allergy, Immunology and Transplantation. “We want to emphasize that food oral immunotherapy and oral food challenges should not be tried at home because of the risk of severe allergic reactions.”
