Recently, the association of CTLA4 gene polymorphism with type 1 diabetes and AITD has been reported in several populations. CTLA4 was originally reported to regulate T-cell activity and T-B cognate interaction. To investigate the role of CTLA4 in autoimmune diseases, we examined the correlation between CTLA4 gene polymorphism and the clinical(More)
Most neuroblastoma identified by mass screening are clearly different from the clinically diagnosed tumors with respect to biology, epidemiology, and outcome. Because the neuroblastomas detected by mass screening have favorable biological features (97% survival rate at 5 years), aggressive surgery may not be appropriate for such tumors. Laparoscopic(More)
In 3 (9 %) of 34 children with biliary atresia, US revealed gallbladder contraction following an oral feed, given on admission, but not with subsequent feeds. Surgery revealed a Kasai type IIIa biliary atresia with a patent communication between the gallbladder and duodenum. We propose that the bile ducts may initially have been patent, but then gradually(More)
We performed serial ultrasonic examinations to differentiate biliary atresia from neonatal hepatitis. The subjects studied were 144 children (100 normal neonates and infants, 31 patients with neonatal hepatitis and 13 patients with biliary atresia). They were examined by ultrasound before, during and after feeding. In 97 out of 100 normal children and all(More)
Different autoimmune mechanisms may be involved in childhood- and adult-onset type 1 diabetes. Our aim was to explore the differences in IA-2 autoantibody epitope recognition between childhood- and adult-onset type 1 diabetes. Therefore, in vitro synthesized radiolabeled IA-2ic (amino acid 601-979), IA-2JM (amino acid 557-629), and IA-2PTP (amino acid(More)
Three Japanese brothers with progressive deterioration of hepatic function and fatty degeneration of the liver eventually leading to hepatic encephalopathy were recently encountered. Each of them had a congenital intrahepatic portosystemic venous shunt due to a patent ductus venosus. Liver dysfunction and hepatic steatosis reverted to normal with surgical(More)
In Japan, crocidolite had been used for asbestos cement pipe and spraying, and amosite had been used for building board and spraying. These two types of asbestos had stopped to use in Japan in the late 1970s. An extreme increase in imported asbestos (all 3 commercial types) was observed between 1960 and 1974. In 1960, 77,000 tons of asbestos were imported,(More)
AIMS To clarify the correlation between serum concentrations of soluble adhesion molecules and diabetic microangiopathy or macroangiopathy in patients with Type 2 diabetes. METHODS Patients with diabetic retinopathy and intima-media thickness of common carotid artery (CCA-IMT) < 1.1 mm were classified as the microangiopathy group (n = 62). Patients with(More)
OBJECTIVE This study was undertaken to assess the usefulness of MR cholangiopancreatography (MRCP) with a half-Fourier acquisition single-shot turbo spin-echo (HASTE) sequence as a noninvasive imaging technique to evaluate biliary or pancreatic disease in young children. SUBJECTS AND METHODS We prospectively examined 45 children (mean age, 3 years) with(More)
The diagnosis of some cases of neonatal jaundice is complicated because of inability to identify the gallbladder, which makes it very difficult to differentiate biliary atresia from neonatal hepatitis even by serial ultrasonic (US) examination. Serial (US) examination after the administration of phenobarbital as a cholagogue at a dosage of 5 mg/kg/day for 5(More)
