Hay fever, the often seasonal allergy that affects between 10 and 20 percent of the American population, is best controlled through a course of patient-adjusted dosing, according to new research published in the September 2008 edition of Otolaryngology – Head and Neck Surgery.

Together with colleagues from the Department of Dermatology and Allergy and the Center for Allergy and Environment (ZAUM) of the Technische Universität München, scientists at the Helmholtz Zentrum München have pinpointed a major gene for allergic diseases. The gene was localized using cutting edge technologies for examining the whole human genome at the Helmholtz Zentrum München

Patients who have had acute allergic-like reactions to nonionic iodinated contrast material rarely develop any serious long-term problems and can be treated safely with commonly used medications according to a recent study conducted by researchers at the University of Michigan Hospitals in Ann Arbor.

There is a link between alcohol consumption and increased risk of perennial allergic rhinitis, according to a recent Danish study of 5,870 young adult women.

In an ongoing effort to determine the anti-inflammatory value of diets rich in some types of fish, scientists studying asthma and allergic reactions have found that a molecule produced by the body from omega-3 fatty acids helps resolve and prevent respiratory distress in laboratory mice.

As if the emotional and financial impact of flood damage isn't bad enough, floodwaters can also bring health problems. H. James Wedner, M.D., professor of medicine and chief of the Division of Allergy and Immunology at Washington University School of Medicine in St. Louis, says after the water recedes, damp homes and businesses are fertile grounds for mold growth, which can cause allergic reactions and asthmatic symptoms in sensitive people.

Moving house or the separation of parents can significantly increase the risk of children developing allergies later on. These are the results from a long-term study correlating life-style, immune system development and allergies, led by the Helmholtz Center for Environmental Research in Leipzig (UFZ), the Helmholtz Zentrum München and the "Institut für Umweltmedizinische Forschung" (IUF) in Duesseldorf.

New evidence blames traffic-related pollution for increasing the risk of allergy and atopic diseases among children by more than fifty percent. What's more, the closer children live to roads, the higher their risk.

Mothers exposed to farms, particularly to barns and farm milk, while pregnant confer protection from allergies on their newborns, according to a group of German researchers, who will present their findings at the American Thoracic Society’s 2008 International Conference in Toronto on Wednesday, May 21.

Women who are stressed during pregnancy may pass some of that frazzlement to their fetuses in the form of increased sensitivity to allergen exposure and possibly future asthma risk, according to researchers from Harvard Medical School who will present their findings at the American Thoracic Society’s 2008 International Conference in Toronto on Sunday, May 18.

Outdoor exposure to environmental irritants such as allergens, pollution, debris and cigarette smoke can cause the mucous membranes of the sinuses to swell, leading to pain, pressure and perhaps even infection. Allergy and sinus sufferers are typically advised by doctors to take medication for relief from all their pain and pressure. But recent studies suggest that there is a new treatment for effective sinus relief.

A new Harris Interactive phone survey conducted among 1,000 allergy sufferers, 1,000 consumers (both allergy sufferers and non-sufferers) and 300 physicians shows that beyond the sneezing, sniffling and watery eyes, allergies also have deep and emotional impacts on a sufferer's mood and self-perceptions.
