The effects of histone deacetylase (HDAC) inhibitors on epithelial-mesenchymal transition (EMT) differ in various types of cancers. We investigated the EMT phenotype in four colon cancer cell lines when challenged with HDAC inhibitors trichostatin A (TSA) and valproic acid (VPA) with or without transforming growth factor-β1 (TGF-β1) treatment. Four colon(More)
Endoscopy for acute nonvariceal upper gastrointestinal bleeding plays an important role in primary diagnosis and management, particularly with respect to identification of high-risk stigmata lesions and to providing endoscopic hemostasis to reduce the risk of rebleeding and mortality. Early endoscopy, defined as endoscopy within the first 24 hours after(More)
BACKGROUND/AIMS Ampullary tumors come in a wide variety of malignant forms. We evaluated the diagnostic accuracy of endoscopy for ampullary tumors, and analyzed the causes of misdiagnosis. METHODS We compared endoscopic imaging and biopsy results to final diagnoses. Types of endoscope, numbers of biopsy specimens taken, and final diagnoses were evaluated(More)
Ceftriaxone is widely used in patients for the treatment of serious gram-negative infections. Ceftriaxone can induce some potential side effects, including neurotoxicity, however, nonconvulsive status epilepticus has rarely been reported. We report a case of acute reversible neurotoxicity associated with ceftriaxone. A 65-yr-old woman with chronic kidney(More)
Background/Aims EUS can detect bile duct stones (BDS) that are undetectable on multidetector computed tomography (MDCT). BDS associated with acute biliary pancreatitis (ABP) are small and tend to be excreted spontaneously. This study evaluated the usefulness of early EUS in patients with ABP and undetectable BDS on MDCT. Methods Forty-one patients with(More)
Most infants with repaired gastroschisis develop normally and remain in good health. About 10% of patients with gastroschisis have other malformations. We report a case of choledocholithiasis and intestinal malrotation in an adolescent with repaired gastroschisis. A 17-year-old girl presented with fever, jaundice, and abdominal pain. She had undergone an(More)
BACKGROUND/AIMS 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) has been used for preoperative staging of colorectal cancer (CRC). However, the diagnostic accuracy of FDG-PET/CT for detection of lymph node or distant metastasis and its prognostic role have not been well established. We therefore evaluated the diagnostic(More)
AIM To assess the efficacy and safety of a patient-positioning device (EZ-FIX) for endoscopic retrograde cholangiopancreatography (ERCP). METHODS A total of 105 patients were randomized to the EZ-FIX (n = 53) or non-EZ-FIX (n = 52) group in this prospective study. Midazolam and propofol, titrated to provide an adequate level of sedation during therapeutic(More)
BACKGROUND/AIMS Urocortin 1, a corticotropin-releasing factor related peptide, increases colonic motility under stressful conditions. We investigated the effect of urocortin 1 on colonic motility using an experimental model with isolated rat colon in which the blood flow and intestinal nerves were preserved. Furthermore, we assessed whether this effect was(More)
