BACKGROUND/AIMS Benign colon (18)F-fluorodeoxyglucose (FDG) uptake is frequently observed in asymptomatic individuals. Aims of this study were to investigate the benign colon uptake by whole body FDG-positron emission tomography (PET) in asymptomatic adults and to correlate those results with colonoscopic and histologic findings. METHODS Among 3,540(More)
Although altered levels of adiponectin have been reported as a potential risk factor in colorectal cancer (CRC), the importance of the role played by adiponectin in colorectal carcinogenesis has not been established. We sought to examine the expression pattern of adiponectin and adiponectin receptors (AdipoRs) in the normal-adenoma-carcinoma sequence and to(More)
GOALS To investigate the association between treatment nonadherence and patients' knowledge of the prescribed medication among individuals with inflammatory bowel disease (IBD), and evaluate the impact of nonadherence on relapse. BACKGROUND The patient's knowledge of the prescribed medication has been identified as an important predictor of treatment(More)
Clostridium difficile (C. difficile) is a common causative agent of pseudomembranous colitis (PMC). C. difficile-associated diarrhea (CDAD) ranges from mild diarrhea to life threatening PMC. Recently, a highly virulent strain of C. difficile polymerase chain reaction ribotype 027 was found in North America, Europe, and Japan. A 52-yr-old woman with(More)
AIM Since positron emission tomography/computed tomography (PET/CT) has been introduced, many incidental findings have been identified. The aim of this study was to assess the clinical significance of incidental findings on PET/CT in patients with gastric cancer. METHODS A total of 421 patients with gastric cancer underwent PET/CT for initial staging.(More)
Obscure gastrointestinal bleeding (OGIB) refers to gastrointestinal (GI) bleeding of unclear origin that persists or recurs after negative findings on esophagogastroduodenoscopy and colonoscopy. OGIB accounts for approximately 5% of all types of GI bleeding. More than 80% of OGIB cases originate in the small bowel. The ability to detect OGIB in the small(More)
BACKGROUND/AIMS It has been known that elderly patients with gastric cancer show worse general condition and higher comorbidities. Therefore, few elderly patients undergo surgery. This study was designed to determine clinicopathological characteristics of gastric cancer in elderly patients and evaluate their survival improvements by the surgical treatment.(More)
A previous genome-wide methylation array for colorectal cancer (CRC) identified aberrant promoter methylation of eyes absent 4 (EYA4). However, the correlations between EYA4 methylation and gene expression, the role played by EYA4 protein in colorectal carcinogenesis, and results of the gene-enrichment and functional annotation analysis have not yet been(More)
The aberrant methylation of CpG islands in the promoter is associated with colorectal cancer (CRC) carcinogenesis. In our previous study, the promoter of alcohol dehydrogenase, iron containing, 1 (ADHFE1) was most highly methylated in CRC compared to normal colorectal mucosa. In this study, we examined the expression and function of the ADHFE1 in CRC. We(More)
The pathogenesis and clinicopathologic characteristics of Epstein–Barr virus (EBV)-negative lymphoepithelioma-like gastric carcinoma (LELC) are still unclear. In addition, it remains controversial whether EBV infection itself affects the prognosis of LELC. Between 1995 and 2011, 145 LELC patients (124 patients with EBV infection and 21 patients without EBV(More)
