Background: Physical therapists frequently come in contact with materials that can potentially cause skin irritation and/or allergies. Nevertheless analyses of professionally relevant sensitization patterns are currently lacking.
Patients and methods: A descriptive analysis of the patch test results from the Information Network of Departments of Dermatology (IVDK) was carried out considering patients employed full-time as physical therapists during the years 2007-2011. Information includes dermatologic diagnoses, possible contact substances and cofactors as well as the "hit list" of the most common allergens.
Results: Among the patients (n = 134) the most common diagnoses (1(st) and 2(nd) ) were allergic contact dermatitis (23.9 %), chronic irritant dermatitis (17.2 %) and atopic dermatitis (19.4 %). In 80 of the 134 patients (59.7 %), the skin lesions were located on the hands. In 62 (46.3 %) of the cases, skin disease was considered work-related. The contact with cosmetics, creams, disinfectants, topical medications and the use of gloves were relevant as putative triggering factors for the respondents. The most common allergens were nickel (II) sulfate (16.5 %), fragrance mix (12.2 %) and fragrance mix II (13.0 %).
Conclusions: In this first comprehensive study of contact allergies among physical therapists in German-speaking countries, a link between skin disease and work was felt likely in nearly 50 % of the tested cohort. To which extent the results shown in this work can be confirmed and which consequences these have for occupational preventive measures should be examined in additional, preferably longitudinal studies.
