Despite lack of evidence, use of a stylet during endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is assumed to improve the quality and diagnostic yield of specimens. The purpose of this study was to compare EUS-FNA specimens obtained with stylet (S+) and without stylet (S−) for: (i) cellularity, contamination, adequacy, and amount of blood and(More)
BACKGROUND Most endosonographers use an EUS needle with an internal stylet during EUS-guided FNA (EUS-FNA). Reinserting the stylet into the needle after every pass is tedious and time-consuming, and there are no data to suggest that it improves the quality of the cytology specimen. OBJECTIVE To compare the samples obtained by EUS-FNA with and without a(More)
BACKGROUND Vascular invasion (VI) in a patient with pancreatic or periampullary cancers precludes surgery and indicates a poor prognosis. Published data on the accuracy of EUS in diagnosing VI is varied. OBJECTIVE The aim of this meta-analysis was to evaluate the accuracy of EUS in diagnosing VI in patients with pancreatic and periampullary cancers. (More)
Using a national database, we report an increasing trend in Clostridium difficile incidence among hospitalized children in the United States from 2003 to 2012. The incidence rate of CDI increased from 24.0 to 58.0 per 10,000 discharges per year (P<0.001) across all age groups, with the greatest increase in children 15 years and older. Infect. Control Hosp.(More)
UNLABELLED The current study tests a hypothesis that nuclear receptor signaling is altered in chronic hepatitis C patients and that the altered pattern is specific to alcohol drinking history. The expression of a panel of more than 100 genes encoding nuclear receptors, coregulators, and their direct/indirect targets was studied in human livers. Gene(More)
Acetaminophen (APAP)-induced acute liver failure (ALF) remains a major clinical problem. Although a majority of patients recovers after severe liver injury, a subpopulation of patients proceeds to ALF. Bile acids are generated in the liver and accumulate in blood during liver injury, and as such, have been proposed as biomarkers for liver injury and(More)
Inconclusive findings on abdominal computerized tomography (CT) scans such as “enlarged or prominent pancreas” are commonly reported; however, their clinical significance is not clearly understood. The objective was to evaluate the efficacy of endoscopic ultrasound (EUS) in a cohort of patients with indeterminate findings on CT. We undertook a(More)
Accumulation of bile acids is a major mediator of cholestatic liver injury. Recent studies indicate bile acid composition between humans and rodents is dramatically different, as humans have a higher percent of glycine conjugated bile acids and increased chenodeoxycholate content, which increases the hydrophobicity index of bile acids. This increase may(More)
Esophageal mucin secretion in patients with reflux esophagitis (RE) is significantly impaired. Rabeprazole augments gastric mucin secretion. We have studied, therefore, the effect of rabeprazole on esophageal mucin secretion in patients with RE. The study was conducted in 15 patients with RE treated with rabeprazole (20 mg QD) for 8 weeks. Esophageal(More)
OBJECTIVES To evaluate the efficacy of botulinum toxin-A in the treatment of postvagotomy gastroparesis. METHODS This open-labeled trial identified and recruited 11 subjects who developed symptomatic gastroparesis after a vagotomy (9 fundoplication, 1 trauma, and 1 exploratory laparotomy). Gastroparesis was defined as an abnormal solid-phase gastric(More)
