Eight children, aged less than 5 years, with atopic dermatitis (AD) and food-induced contact urticaria are described. These cases illustrate the clinical importance of food-induced contact urticaria. The symptoms can be easily provoked and imitated in children under 4 years of age using the 'Skin Application Food Test' (SAFT). This test includes the application of foods on the skin, in the form they are consumed. The clinician should pay attention to clinical symptoms of immediate-contact reactions, easy to recognize. The common skin symptoms are swollen face, in particular the hps, and itching or pain in the mouth and (contact) urticaria. Another dominating symptom is evident refusal of foods. Non-immunological irritation reactions are also common in these children. Confusion with irritation reactions is first avoided of all by strict selective interpretation of the history told by the mother; and second, both the SAFT and the CAP RAST are positive only in immune-mediated processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
