Benign esophageal lesions have a wide spectrum of clinical and pathologic features. Understanding the endoscopic and pathologic features of esophageal lesions is essential for their detection, differential diagnosis, and management. The purpose of this review is to provide updated features that may help physicians to appropriately manage these esophageal(More)
AIM The usual bile duct stone may be removed by means of Dormia basket or balloon catheter, and results are quite good. However, the degree of difficulty is increased when stones are larger. Studies on the subject reported many cases where mechanical lithotripsy is combined with a second technique, e.g. electrohydraulic lithotripsy (EHL), where stones are(More)
AIMS This study aimed to investigate the effect of caffeic acid phenethyl ester (CAPE), an active component isolated from honeybee propolis, in inducing apoptosis in human pancreatic cancer cells. METHODS Inhibition of viability of BxPC-3 and PANC-1 cell lines induced by CAPE was estimated by a trypan blue dye exclusion test. The type of cell death in(More)
AIM To evaluate the relationship between clinical information (including age, laboratory data, and sonographic findings) and severe complications, such as gangrene, perforation, or abscess, in patients with acute acalculous cholecystitis (AAC). METHODS The medical records of patients hospitalized from January 1997 to December 2002 with a diagnosis of(More)
Scurvy is a nearly-forgotten disease in developed countries where adequate nutrition is easily available. It still may occur, however, when, for a variety of reasons, people fail to eat a diet containing adequate vitamin C. We report the case of a 52-year-old patient with depression who developed scurvy.
AIM To investigate acute transient hepatocellular injury in patients with cholelithiasis and cholecystitis but no evidence of choledocholithiasis. METHODS The medical records of patients with cholelithiasis who underwent cholecystectomy between July 2003 and June 2007 were retrospectively reviewed. Imaging studies to detect common bile duct (CBD) stones(More)
BACKGROUND AND AIM The treatment efficacy of peginterferon plus ribavirin for patients with HCV genotype 1 is inferior to that in patients with HCV genotype 2, but the efficacy among patients with mixed HCV genotype 1 + 2 is less clear. We compared the treatment outcome of peginterferon alpha-2b plus ribavirin among naïve chronic hepatitis C patients in(More)
BACKGROUND/PURPOSE For patients undergoing gastric surgery because of complications of peptic ulcers, such as bleeding or perforation in the pre-Helicobacter pylori eradication era, their infection status was not surveyed or it was neglected altogether. Previous reports have shown spontaneous clearance of H. pylori in these patients but the determining(More)
PURPOSE To determine whether exposing hepatocellular carcinoma (HCC) to low dose radiation increases the efficacy of dendritic cell-mediated immunotherapy for HCC. METHODS Tumour specimens collected from 20 recruited patients with HCC were cultured in primary culture (half successfully) and then exposed to low-dose radiation (0.5 Gy). Immature DCs derived(More)
BACKGROUND Chemotherapy agents, particularly those that can induce apoptosis, are the major intervening strategy in the treatment of leukemia. In this study, we investigated the effects of baicalin (a compound obtained from Scutellaria baicalensis Georgi and S. rivularis Benth Labiateae) on the viability, induction of apoptosis and associated mechanism in(More)
