title: Atopic dermatitis: etiology and pathogenesis.
abstract: Atopic dermatitis is a recognizable phenotype that most likely results from several mechanisms. An increasing number of children with atopic dermatitis are recognized as having immune defects, although the exact incidence of such immunodeficiency states among patients with atopic dermatitis is unknown. Children with atopic dermatitis who suffer recurrent or persistent infections should undergo immunologic evaluation. Ideally, this should include evaluation of cell-mediated immunity as well as neutrophil and monocyte chemotaxis. Further investigation into the beta-blockade theory may enhance our understanding of atopic dermatitis. Careful attention to factors exacerbating atopic dermatitis is essential in understanding this problem. Abnormal sweating, dry skin, sensitivity to contactants, and emotional stress should always be considered in evaluation of children with atopic dermatitis.
