Prevalence of fish and shellfish allergy: A systematic review.

Background: Accurate information on the prevalence of food allergy facilitates a more evidence-based approach to planning of allergy services and can identify important geographic variations.

Objective: To conduct a systematic review to assess the age-specific prevalence of fish and shellfish allergy worldwide.

Methods: Searches were conducted using Web of Science and PubMed.

Health-related quality of life in children with perceived and diagnosed food hypersensitivity.

Background: The few studies measuring health-related quality of life (HRQL) in food hypersensitivity (FHS) have found significantly reduced HRQL in patients and their families, particularly in the areas of family and social activities, emotional issues and family economy. One aspect that has not been studied is the effect of suspected FHS (food allergy/intolerance) vs. diagnosed FHS [based on a food challenge or a positive skin prick test (SPT) and good clinical history] on HRQL.
