BACKGROUND Anisakis simplex is responsible for allergic symptoms after repeated ingestion or contact with parasitized fish. OBJECTIVE To further analyze type I and IV immunologic mechanisms in a group of patients with allergic reactions to A simplex, we performed prick-by-prick testing with A simplex larvae and patch tests with live, cooked, or frozen larvae of the A simplex parasite. METHO...

The EAACI recommends that the positive control, i.e. the histamine prick, could be used only to prove that the skin can react [20] . This means that the size of the allergen wheals are to be understood irrespective of the precise size of the histamine wheal. However, others have had a hunch that sizes of the allergen wheals must be dependent of the skin sensitivity and that this sensitivity cou...

We have tested the hypothesis that intradermal testing is a more effective method for determining the drug responsible for anaesthetic anaphylactic reactions than prick testing in 212 consecutive patients, aged more than 10 yr, referred to an anaesthetic allergy clinic over a 4-yr period. The study was a prospective, non-randomized design. Intradermal testing was conducted using a previously de...

Background: Despite rare reports of persimmon anaphylaxis, the association of persimmon with natural rubber latex is low or undetermined, and latex-fruit syndrome presenting with anaphylaxis caused by persimmon has not been reported. Methods: Allergy skin testing were performed for aeroallergens, persimmon and plant foods, including those implicated in the latex-fruit syndrome and local fruits....

DESIGN Case-controls matched for age and sex. SETTING Children's day wards in two teaching hospitals. INTERVENTION Open food challenge with peanut. SUBJECTS 15 children with res...
