Overview of Yusho

High amounts of PCBs and PCDFs are still present in a number of patients with Yusho. The majority of laboratory findings, except for triglyceride concentration, were within normal limits throughout the clinical course. However, the patients still suffered from various mucocutaneous and subjective symptoms, and these symptoms were correlated to the blood levels of polychlorinated congeners. The development of therapeutic interventions is warranted in the near future.
