Relation between vesicular eruptions on the hands and tinea pedis, atopic dermatitis and nickel allergy.

摘要

The aetiology of vesicular eruptions on the palms and on the sides of the fingers (pompholyx) is unclear. The present study was undertaken to establish whether tinea pedis, atopic dermatitis or nickel allergy is a risk factor for development of vesicular eruptions. Three-hundred-and-ninety-eight individuals (included from an ongoing population study on hand eczema in twins) were included. A history of previous hand eczema and atopic dermatitis was taken, and a clinical examination including a patch test with nickel was performed. A test sample for tinea pedis was taken from the fourth interdigital space on the right foot. The relative risk for vesicular eruptions present in individuals with tinea pedis was 3.58 (confidence limits 1.19-10.82, p < 0.05). For individuals with atopic dermatitis, relative risk was 1.44 (confidence limits 0.34-6.07, n.s.) and for those with nickel allergy it was 0.45 (confidence limits 0.06-3.36, n.s.). A relationship between tinea pedis and vesicular eruptions on the hands was statistically confirmed in the present study. In this part of the population study material, no association with atopic dermatitis or nickel allergy was observed.
