[Dermatological findings in the annual examination of the patients with Yusho in 1993-1994].
We reported the grades of severity of skin symptoms and the blood PCB patterns and concentrations in Yusho patients who were examined in the annual examinations in 1993 and 1994. The skin severity grades and skin severity scores showed the same tendency as recorded in the last 15 years. Approximately 20% of the patients, however, claimed the tendency of recurrence of skin infections and/or infected epidermal cysts, and still approximately 30% of the patients exhibited acneiform eruptions. Ten patients recorded with more than 6 points of skin severity scoring in these examinations were further investigated their initial skin severity grades and blood PCB patterns and concentrations. It was found that most of their blood PCB patterns showed the A pattern, and the level of the blood PCB in one patient was 55.5 ppb in the initial stage. Five patients out of 10 patients still have more than 10 ppb of blood PCB concentration. Thus, it is concluded that small populations of Yusho patients still have active skin symptoms with considerable blood PCB levels even at present.
