UNLABELLED Only 20% of patients with chronic hepatitis C (CHC) will develop cirrhosis, and fibrosis progression remains highly unpredictable. A recent genome-wide association study identified a genetic variant in the patatin-like phospholipase-3 (PNPLA3) gene (rs738409 C>G) associated with steatosis that was further demonstrated to influence severity of(More)
BACKGROUND AND AIMS Elicitation of an innate immune response to bacterial products is mediated through pattern recognition receptors (PRRs) such as the toll-like receptors (TLRs) and the NODs. The recently characterised Asp299Gly polymorphism in the lipopolysaccharide (LPS) receptor TLR4 is associated with impaired LPS signalling and increased(More)
Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Risk factors for post-ERCP pancreatitis (PEP) are both patient-related and procedure-related. Identification of patients at high risk for PEP is important in order to target prophylactic measures. Prevention of PEP includes administration of nonsteroidal(More)
PURPOSE To assess the utility of dynamic MR pancreatography in the evaluation of the behavior of the pancreatic duct after secretin stimulation and to estimate pancreatic exocrine reserve in patients suspected of having acute recurrent or chronic pancreatitis. MATERIALS AND METHODS Ten healthy volunteers and 13 patients suspected of having pancreatic(More)
PURPOSE Cytokines have been associated with the development of sepsis and diffuse tissue injury following septic or endotoxic challenges in humans. Furthermore, relative organ-system dysfunction, not specific organ dysfunction, appears to predict outcome from critical illness. We hypothesized that persistence of inflammatory cytokines within the(More)
A novel transoral incisionless fundoplication (TIF) procedure using the EsophyX system with SerosaFuse fasteners was designed to reconstruct a full-thickness valve at the gastroesophageal junction through tailored delivery of multiple fasteners during a single-device insertion. The safety and efficacy of TIF for treating gastroesophageal reflux disease(More)
BACKGROUND Self-expandable metal stents (SEMSs) have been suggested for the treatment of benign upper GI leaks and perforations. Nevertheless, uncomplicated removal remains difficult. Placement of a self-expandable plastic stent (SEPS) into an SEMS can facilitate retrieval. OBJECTIVES This study reviews our experience with sequential SEMS/SEPS placement(More)
UNLABELLED The incidence of hepatocellular carcinoma (HCC) is increasing in Western countries. Although several clinical factors have been identified, many individuals never develop HCC, suggesting a genetic susceptibility. However, to date, only a few single-nucleotide polymorphisms have been reproducibly shown to be linked to HCC onset. A variant(More)
Gut-derived, endotoxin-mediated hepatocellular damage has been postulated to play a crucial role in the pathogenesis of alcohol-induced liver injury in rodents. Endotoxins induce production of tumor necrosis factor alpha (TNF-alpha) by Kupffer cells via Toll-like receptor (TLR) 4 and contribute to liver injury. This study addressed the contribution of other(More)
BACKGROUND Pancreatic-fluid collections are frequent sequelae of acute and chronic pancreatitis, and endoscopic drainage of these collections has gained acceptance as an alternative to surgical drainage. METHODS Patient data, collection characteristics, drainage technique, and outcomes were obtained through chart review and prospective follow-up for 116(More)
