Gastrointestinal bleeding (GIB) is a common presentation with significant associated morbidity and mortality, the prevalence of which continues to rise with the ever-increasing aging population. Initial evaluation includes an esophagoduodeonscopy and/or colonoscopy, which may fail to reveal a source. Such cases prove to be a dilemma and require(More)
The prognosis and management of chronic viral hepatitis mainly depend on the extent of liver fibrosis, particularly in chronic hepatitis C. Liver histologic analysis is still considered the reference standard in the assessment of liver fibrosis despite the interobserver and interobserver variability in staging and some morbidity and mortality risks. Thus,(More)
There is a fine balance in the mutual relationship between the intestinal microbiota and its mammalian host. It is thought that disruptions in this fine balance contribute/account for the pathogenesis of many diseases. Recently, the significance of the relationship between gut microbiota and its mammalian host in the pathogenesis of obesity and the(More)
The obesity epidemic has drastically impacted the state of health care in the United States. Paralleling this epidemic is the incidence of diabetes mellitus, with a notable shift toward a much younger age of onset. While central to the pathogenesis of diabetes associated with obesity is the role of inflammation attributed to "adiposopathy." Emerging data(More)
INTRODUCTION The prevalence of gastroesophageal reflux disease continues to increase with the aging population and the obesity epidemic. Therapeutic failures can have significant detrimental effects in patients. Recently, dexlansoprazole MR and esomeprazole strontium were introduced to the class of proton pump inhibitors (PPIs).

Interferon has been the backbone of HCV treatment since this agent was first introduced nearly two decades ago. Interferon acts to eradicate HCV via two mechanisms: by directly inhibiting HCV replication via an indirect anti-viral mechanism and by modulating an immune response against hepatocytes infected with HCV. The current treatment of chronic HCV(More)
Hepatic encephalopathy (HE) is a commonly encountered sequela of chronic liver disease and cirrhosis with significant associated morbidity and mortality. Although ammonia is implicated in the pathogenesis of HE, the exact underlying mechanisms still remain poorly understood. Its role in the urea cycle, astrocyte swelling, and glutamine and(More)
Sleep dysfunction is an epidemic, the implications of which have a profound impact on a variety of gastrointestinal disease. Recent data suggests a relationship between sleep dysfunction and intestinal dysbiosis, a known proinflammatory driver. This article evaluates the interplay between sleep dysfunction and gastrointestinal health and disease, with a(More)
Pancreaticopericardial fistula is an extremely rare complication of chronic pancreatitis and is virtually unheard of in the setting of acute pancreatitis. A 67-year-old male presented with acute pancreatitis complicated by pancreaticopericardial fistulization. The patient's initial presentation was consistent with tamponade physiology. Computed tomography(More)
Lynch syndrome (LS), also known as hereditary nonpolyposis colorectal cancer (HNPCC), is an autosomal dominant genetic condition which predisposes patients to several different types of cancer, most notably colorectal cancer [1]. LS can be implicated in up to 5 % of colorectal cancers (CRC), making it the most common form of hereditary CRC [2]. However, in(More)
