Dyshidrotic eczema and occupation: a descriptive study.
Dyshidrotic eczema (DE) is a chronic and/or recurrent vesicular eczema of the palmar sides of the hands and sometimes the soles of the feet. The major aetiologies to be considered are atopic DE, contact DE, systemic contact DE and DE due to fungal or microbial allergy. To clarify the role of occupational contact allergens, 59 workers with DE were examined to determine whether they had atopy, environmental contact sensitization and/or contact allergy coupled with work activity. For all, patch testing was carried out using the European standard series and the material brought in by the patients. No significant difference was found between the rate (42.4%) of history of atopy among the 59 workers with DE and that (30.6%) observed among 160 workers with other forms of hand eczema (HE). Positive patch test reactions were found in 72.8% of dyshidrotic patients. A relationship to occupational activity was strong for 18 (30.5%) of them but this rate was significantly lower than that (55%) observed among the 160 with other types of eczema. Results of the present study showed that contact sensitization is as much involved in workers with DE as in workers with other form of HE, even though the relationship to work is significantly less frequent for DE. It also suggests that atopic histories are no more involved in DE than in other forms of HE.
