The purpose of the study was to evaluate the incidence of hand dermatitis, the impact of potential risk factors and the efficacy of skin bioengineering in a prospectively followed cohort of apprentice nurses. 104 participants were prospectively followed for 3 years. Before the start of training, after about 1 year and in the third year of occupational exposure, a standardized questionnaire was distributed, and a clinical examination with skin bioengineering of the dorsum of hand and forearm was performed. The 12-month period prevalence of self-reported symptoms of hand dermatitis was 36.5% 95%-confidence interval (CI) 27.3-46.6 at intermediate follow-up and 43.3%(95%-CI 33.6-53.3) at the final examination. Apprentices with self-reported symptoms at the final examination showed a significant increase of transepidermal water loss (TEWL) at the dorsal hand from 10.15 g/ m2h to 13.55 g/m2h. TEWL at this site did, at the initial examination, not differ significantly be-tween persons who later reported symptoms of hand dermatitis at the final examination and those who did not (10.50 g/m 2h versus 10.15 g/m2h, respectively). Our results do not support the notion that an increased basal TEWL is a good indicator for hand dermatitis risk.
