Epidemiology of Contact Dermatitis in North America: 1972

Arch Dermatol. 1973;108(4):537-540. doi:10.1001/archderm.1973.01620250025006
Abstract

Twelve hundred subjects in North America were patch tested identically with 16 allergens. Thirteen dermatologists representing ten separate centers participated in this epidemiologic study. The most common sensitizers observed include nickel sulfate, potassium dichromate (VI), thimerosal (Merthiolate), p-phenylenediamine, ethylenediamine, neomycin sulfate, and turpentine oil. Results of this North American study are compared to those published by the International Contact Dermatitis Research Group. The data permits a more rational selection of antigens for efficient patch testing in North America. A new list of 19 screening allergens recommended by the North American Contact Dermatitis Group has been published.
