Association of food allergy and atopic dermatitis exacerbations.

Background: Atopic dermatitis (AD) and food allergy frequently coexist in children.

Objective: To examine the association between food allergy and AD.

Methods: Between 2001 and 2011, children referred to our tertiary care center underwent double-blind, placebo-controlled food challenges (DBPCFCs) for one or more suspected food allergies as part of regular care.

Development and validation of challenge materials for double-blind, placebo-controlled food challenges in children.

Background: The use of double-blind, placebo-controlled food challenges (DBPCFCs) is considered the gold standard for the diagnosis of food allergy. Despite this, materials and methods used in DBPCFCs have not been standardized.

Objective: The purpose of this study was to develop and validate recipes for use in DBPCFCs in children by using allergenic foods, preferably in their usual edible form.
