title: A practical overview of pediatric atopic dermatitis, part 1: epidemiology and pathogenesis.
abstract: Atopic dermatitis (AD) is a multisystem inflammatory disorder that is part of the spectrum of atopy, a series of conditions in which hyperreactivity and allergic symptoms are triggered by a series of causes including environmental allergens and irritants. Atopic dermatitis affects approximately one-quarter of children in developed countries and can have a negative impact on quality of life. In part 1 of this series addressing AD, the epidemiology and pathogenesis of AD are reviewed with an overview of skin barrier function. Later parts will address triggers, AD grading, differential diagnosis, comorbidities, and treatment options.
