BACKGROUND Only one previous study, via telephone call, on the prevalence of self-reported food allergies has been performed in Portugal, in a small sample of adults. The objective of this study was to determine the prevalence of self-reported and probable food allergy, analyze the clinical features and involved foods in Portuguese adults. METHODS Population-based, cross-sectional study perfo...

BACKGROUND Natural rubber latex (NRL) allergy in workers using rubber gloves has been an occupational health problem for the last 10 years. In the case of the occupational agents, clinical history may be far from conclusive; hence, appropriate provocation should be carried out. The objective was to evaluate the usefulness of the nasal challenge test in the diagnosis of allergic rhinitis in subj...

conclusions our findings did not support the effect of cigarette smoking on spt reactivity to pollen and weeds aeroallergens. however, male were significantly more sensitive than female in terms of sensitivity to some allergens. results the results of this study indicated that 41.4% of patients with allergic rhinitis was smoker with ages ranged from 15 to 70 years. the result of this study also...

BACKGROUND The skin prick test (SPT) is regarded as an important diagnostic measure in the diagnostic work-up of food allergy. Objective To evaluate the diagnostic capacity of the SPT in predicting the outcome of oral food challenges, and to determine decision points for the weal size and the skin index (SI) that could render double-blind, placebo-controlled food challenges unnecessary. METHO...

Background: Skin prick testing is the most common diagnostic tool used by allergists. There are limited, international rules on interpreting and reporting skin test results in a meaningful way. Aim: This communication describes methods to express the results of skin prick tests in a meaningful way. It is recommended to use allergen extracts with defined composition, potency and stability, to ke...

Recently we found that ultraviolet B (UVB) irradiation in erythematous doses significantly inhibited the immediate type hypersensibility reaction in the skin. In the present study we investigated the effects of different wavelengths on the skin prick test reaction (SPT). The forearm of ragweed allergic patients was irradiated with increasing doses of ultraviolet A (UVA), visible light (VIS) or ...

Results Of 1860 patients screened, 1097 (58.9 %) gave history of food allergy. Of the history positive patients 470 were skin prick tested . 29.3 % (138/470) exhibited positive reactions to one or more food(s). Rice elicited SPT positive reaction in maximum ( 6.2 %) cases followed by blackgram (5.9 %), lentil (5.5 %), citrus fruits (5.3 %), pea (3.8 %), maize (3.8%) and banana (3.6 %). Among fo...

OBJECTIVES To assess the effect of exposure to flour dust on pulmonary function tests, prevalence of symptoms (respiratory, allergic/irritating) and parameters of allergic sensitization in terms of skin prick test, and bronchial hyper-responsiveness. MATERIAL AND METHODS 43 bakers (with at least 2 years of occupational exposure) working at different bakeries in Ismailia city, Egypt; and 64 co...

Main indoor allergens for humans are from house dust mites. There are more than 30 allergens in Dermatophagoides farinae but only fourteen allergens have been identified from this mite including Der f 1-3, 6, 7, 10, 11, 13-18, and 22. A native allergen protein (Der f 24, 90 kDa) was purified from D. farinae by gel filtration and anionic exchange liquid chromatography combined with IgE immunodet...
