Chronic hepatitis C virus (HCV) infection in children is a problem affecting thousands of children worldwide. Although standard interferon (INF) has better efficacy in pediatric patients than in adults, results in children with genotype 1 are poor; response rates to combination treatment with standard INF and ribavirin are better but the treatment requires(More)
OBJECTIVES This study compared p53 expression with B7-H4, a novel cancer biomarker, in pancreatic ductal adenocarcinoma (PDA) resection specimens and in a pilot series of endoscopic ultrasound-guided fine-needle aspirations (EUS-FNAs). METHODS B7-H4 and p53 expression were evaluated by immunoperoxidase methods in 36 PDA and 15 EUS-FNA specimens and were(More)
BACKGROUND & AIMS Iron overload may cause or contribute to hepatic injury and fibrosis. Mutations in the HFE gene may influence development or progression of chronic liver disease by increasing iron stores or modulating immune responses. The aim of this work was to assess the influence of HFE mutations and serum and hepatic measures of iron status on(More)
UNLABELLED Studies of the prognostic value of Ishak fibrosis stage are lacking. We used multi-year follow-up of the Hepatitis C Antiviral Long-Term Treatment Against Cirrhosis (HALT-C) Trial to determine whether individual Ishak fibrosis stages predicted clinical outcomes in patients with chronic hepatitis C. Baseline liver biopsy specimens from 1050(More)
Schistosomiasis is a major health problem in the developing world and for international travelers to the endemic countries. Existing strategies to control schistosomiasis have had limited successes so far. The addition of an effective vaccine in existing control measures would be greatly beneficial in reducing the impact of the disease. In this regard,(More)
PURPOSE To determine the degree of correlation between radiographic size and true gross pathologic size for subjects with primary hepatocellular carcinoma (HCC). METHODS AND MATERIALS This analysis included 18 patients with 27 tumors who underwent either partial hepatectomy or orthotopic liver transplantation for HCC at the University of Colorado Hospital(More)
PURPOSE We investigated the etiology of acute hepatitis in three children with systemic Juvenile Idiopathic Arthritis (sJIA) taking Interleukin-1 receptor antagonist (IL1RA). METHODS Laboratory and clinical data for three children with sJIA diagnosed at ages 13 months to 8 years who developed acute hepatitis during treatment with IL1RA were reviewed for(More)
BACKGROUND Argon plasma coagulation (APC) has been used to trim uncovered Elgiloy stents, but the extent of thermal damage and bile duct injury is not known. The goal of this study was to evaluate the safety and efficacy of APC for this application. METHODS Eight Elgiloy (covered and uncovered) and four nitinol stents were deployed in the bile duct at(More)
Current prostate biopsy cores have a very low diagnostic yield. These biopsies often fail to diagnose prostate cancer since 90% of cores are histopathologically classified as benign. The concentrations of endogenous fluorophores in prostate tissue vary with disease states. Thus, fluorescence spectroscopy could be utilized to quantify these variations for(More)
