title: Dermatological findings in children exposed transplacentally to heat-degraded polychlorinated biphenyls in Taiwan.
abstract: We studied 128 children who were transplacentally exposed to polychlorinated biphenyls and dibenzofurans in Taiwan, their parents and siblings who were directly exposed, and 115 control children. Direct exposure of the mothers stopped in 1979 and the children were born as late as 1985. At birth, exposed children had increased rates of hyperpigmentation, eyelid swelling and discharge, deformed nails, acne, natal teeth and swollen gums compared to controls. On examination, they had a much higher rate of dystrophic finger-nails and pigmented or dystrophic toe-nails than controls. They also had an increased rate of hyperpigmentation and acne. In addition they had more generalized itching, localized skin infections and hair loss. The findings seen in transplacentally exposed children differ from those seen in people directly exposed, particularly in the latter group in higher prevalence of acne.
