[Evaluation of dermatological symptoms of Yusho patients in the annual examination in 2003-2004].
We evaluated the severity grades and the skin severity scores of the skin symptoms who visited the annual examinations of Fukuoka prefecture in 2003 and 2004. The severity of skin symptoms improved significantly in the first 20 years; nowadays, however, further improvement can hardly be observed. More than 36 years have passed since the Yusho incident, and about 60% of the patients currently present no skin symptoms. In contrast, in about 40% of the patients, characteristic skin symptoms of Yusho, such as pigmentation of skin, black comedones and acneform eruptions, could still be observed. Using Peason's correlation coefficient test and Spearman's correlation coefficient test, we analyzed correlation between "PCB pattern" and the blood PCB concentration, the skin severity grade and the skin severity scores. However, we could not find out any obvious correlation.
