A new polypore in the genus Fomitopsis was discovered in Kangwon Province, Korea. The species was morphologically similar to Fomitopsis rosea and F. cajanderi, but the pinkish white pore surface, the size and shape of the pores and the number of sterigmata were different enough for it to be distinguished from the recorded species of Fomitopsis. Based on the(More)
BACKGROUND Inflammatory bowel disease (IBD) is rare in Asian children and few reports on pediatric IBD have appeared. AIMS We, therefore, investigated the incidence trends and clinical characteristics of pediatric IBD in Korea. METHODS We enrolled 48 children with Crohn's disease (CD) and 14 children with ulcerative colitis (UC) from 1996 to 2007.(More)
DESCRIPTION Total pancreatectomy with islet autotransplantation (TPIAT) is a surgical procedure used to treat severe complications of chronic pancreatitis or very high risk of pancreatic cancer while reducing the risk of severe diabetes mellitus. However, clear guidance on indications, contraindications, evaluation, timing, and follow-up are lacking. (More)
OBJECTIVE Crohn's disease (CD) is an intractable inflammatory bowel disease (IBD) of unknown cause. Recent meta-analysis of the genome-wide association studies (GWAS) and Immunochip data identified 163 susceptibility loci to IBD in Caucasians, however there are limited studies in other populations. METHODS We performed a GWAS and two validation studies in(More)
OBJECTIVES We evaluated the frequencies and clinical consequences of mutations in the genes encoding cationic trypsinogen, serine protease 1 (PRSS1), and serine protease inhibitor Kazal type 1 (SPINK1) in children with acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP). PATIENTS AND METHODS The study population consisted of 32 children with(More)
To evaluate the monophyly of Fomitopsis and elucidate phylogenetic relationships of its members, partial nuclear large subunit (partial 28S) ribosomal RNA genes were sequenced from 10 species of Fomitopsis and 15 related species. Phylogenetic analyses indicated that Fomitopsis was phylogenetically heterogeneous and its members were divided into three(More)
BACKGROUND There is debate about whether intraoperative cholangiography (IOC) should be performed routinely or selectively during laparoscopic cholecystectomy (LC) in patients with suspected choledocholithiasis. The timing of endoscopic retrograde cholangiopancreatography (ERCP) in these patients also is an issue. We reviewed the experience in our center,(More)
PURPOSE To evaluate the efficacy of stent placement for the treatment of portal vein (PV) stenosis or occlusion in pediatric liver transplant recipients. MATERIALS AND METHODS Written informed consent was obtained from a legal guardian, and our institutional review board approved this study. Percutaneous (n = 10) or intraoperative (n = 2) stent placement(More)
INTRODUCTION AND AIMS Wide phenotypic and genotypic heterogeneities in Wilson's disease (WD) have been reported, hampering the study of their correlations. The goal of this study was to identify the factors related to these diversities. METHODS Clinical courses and molecular genetic characteristics were analysed in 237 unrelated Korean WD families. The(More)
PURPOSE To evaluate the clinical efficacy and safety of fluoroscopically guided balloon dilation for pyloric stricture associated with Crohn disease (CD) while monitoring the outcome. MATERIALS AND METHODS Five patients (age range 15-34 y) were diagnosed with symptomatic pyloric stricture associated with CD between November 2006 and August 2009. All five(More)
