In situ graft-trimming method using polyester vascular prosthesis for inferior vena cava reconstruction after hepatectomy.

Hepatectomy for secondary liver cancer that has invaded the inferior vena cava (IVC) can be the only way to achieve long-term survival. We describe a method for hepatectomy combined with partial IVC resection without venous bypass circulation and an in situ graft-trimming method to avoid graft size mismatch after reconstruction. We carried out left hepatectomy extended to segment 1 with partial IVC resection first.

Prevention of mildly overweight children from development of more overweight condition.

Background: A follow-up study has reported that not only highly obese but also mildly obese children are becoming heavier during the elementary school children. Then we determined the effect of programs for the screening and treatment of overweight elementary school children whether the programs prevented mildly overweight children from development of more overweight condition.

Methods: Subjects were 40 overweight children who participated in both screening and treatment programs.

Effect of age and overweight on the QT interval and the prevalence of long QT syndrome in children.

The change in QT interval with age during childhood of normal children and children with long QT syndrome (LQTS) and the effects of body mass index on the QT interval have not been studied in detail. The prevalence of LQTS in children is not well known. We measured 3 consecutive QT and RR intervals in 4,655 children.
