the prevalence of food allergy is different in various nations. the identification of the most common food allergens is a priority in any population to provide effective preventive and curative measures. the aim of this study is to determine the most common food allergens in iranian children. one hundred and ninety children with skin, respiratory or gastrointestinal symptoms, which were thought...

background: diagnosis of food allergy is difficult in children. food allergies are diagnosed using several methods that include medical histories, clinical examinations, skin prick and serum-specific immunoglobulin e (ige) tests, radio-allergosorbent test (rast), food challenge, and supervised elimination diets. in this study we evaluated allergies to cow's milk, egg, peanut, and fish in c...

There are few reliable epidemiologic data on the overall frequency and importance of allergy. We describe a practical method for quantifying the concentration of both amorphous and morphologically defined antigens in the air. A high volume air sampler is used to collect airborne particles and has a facility to separate samples into different particle sizes. Samples are tested for allergenic act...

In an eosinophilic population of 47 boys of the same age, a large proportion (92%) were helminth infested or atopic, or both, compared with 36% of 36 controls. The methods used to detect these conditions were not costly or elaborate, except for the radioallergosorbent test, which was used to measure concentrations of circulating IgE antibodies to atopic allergens. It is suggested that an econom...

IgE-mediated allergic reactions have been postulated to contribute to respiratory reactions seen in workers exposed to grain dusts. In an attempt better to define the prevalence of IgE antibodies in workers exposed to grain dusts, we performed the radioallergosorbent test (RAST) on worker sera using both commercial allergens prepared from grain and worksite allergens prepared from grain dust sa...

OBJECTIVE To assess whether, on the basis of one blood test, penicillin allergy might be excluded sufficiently for general practitioners to give oral penicillin to patients claiming a history of penicillin allergy. DESIGN Prospective study of patients referred by general practitioners. SETTING Outpatient allergy clinic in a district general hospital. PATIENTS 175 referred patients who gav...

Basidiospores of Calvatia cyathiformis have been identified in aerobiological studies, and spore extracts have demonstrated significant skin and radioallergosorbent test reactivity insensitive patients. Although fruiting bodies of Calvatia craniiformis, C. rubroflava, and C. gigantea re also relatively common, basidiospores of these species cannot be specifically identified from the atmosphere....

A 21-year-old patient experienced asthmatic attacks when cleaning the cage of his budgerigar. Skin tests and radioallergosorbent test were positive to grass pollen and negative for budgerigar feathers and feces. When the food of the bird, a mixture of grain, was tested, a positive reaction to millet was found. Nasal provocation test with millet was positive. Specific immunoglobulin E antibodies...
