Contact dermatitis: epidemiology and frequent sensitizers to cosmetics.
Contact dermatitis is defined as a pattern of inflammatory response that may occur as a result of contact with external factors. The two most common causes are irritants and allergens. Very few reliable data on prevalence and incidence of contact dermatitis exist, and data from the few studies that have been carried out cannot be compared because of differences in methodology. Occupational contact dermatitis constitutes up to 30% of all occupational diseases for which compensation is payable and affects sufferers' home and social lives as well as their working lives. Patients can be advised about the use of personal protective equipment and creams and emollients to avoid or ameliorate their condition, but there is little epidemiological evidence for their efficacy. Patch testing, using the European Standard Series of Allergens, is necessary to determine which agent is responsible for the condition. Fragrances and preservatives used in cosmetics are among the most common allergens in contact allergic dermatitis, although the frequency of contact allergy in the general population is small. It is to be hoped that the European Dermato-Epidemiology Network Fragrance Study will go some way to addressing the need for a large population-based epidemiological study in order that public health organizations can give reliable advice about avoiding and treating contact dermatitis.
