BACKGROUND AND AIM An endoscopic forceps biopsy (EFB) carries the risk of missing the neoplastic foci within a polyp as only a small portion of the lesion is sampled using this technique. Accordingly, the histological examination of specimens obtained by an EFB is of limited accuracy and patient management based on the histological findings is(More)
Although the incidence of perforation after endoscopic procedures of the colon is low, the rising number of diagnostic colonoscopies could pose relevant health problems. Optimizing treatment may reduce the probability of severe complications. This study aimed to determine perforation frequency and the management of perforations that occurred during(More)
BACKGROUND AND AIM Delayed post-polypectomy hemorrhage is a rare but serious complication. The aim of this study was to identify risk factors for the development of delayed post-polypectomy hemorrhage. METHODS This was a retrospective case-control study of patients who developed delayed hematochezia after receiving colonoscopic polypectomy. The control(More)
A 70-yr-old woman complained of left sided chest pain and non-bilious vomiting for four days after taking a gastric bloating agent for an upper gastrointestinal study. The chest radiography revealed gastric air-fluid levels and bowel loops in the left thoracic cavity. An emergency thoracotomy was performed. The abdominal organs (stomach, spleen, splenic(More)
AIM To analyze the clinical characteristics of patients diagnosed with Fitz-Hugh-Curtis syndrome. METHODS The clinical courses of patients that visited St. Mary's Hospital with abdominal pain from January 2005 to December 2006 and were diagnosed with Fitz-Hugh-Curtis syndrome were examined. RESULTS Fitz-Hugh-Curtis syndrome was identified in 22 female(More)
OBJECTIVES The aim of this study was to evaluate safety and efficacy of high-intensity focused ultrasound (HIFU) for advanced pancreatic cancer (PC). METHODS Patients with PC TNM stage III or IV were included. Magnetic resonance imaging was performed 2 weeks before and after the HIFU. The ablating tumor volume was calculated by ratio of the nonperfused(More)
Influenza A virus has evolved and thrived in human populations. Since the 1918 influenza A pandemic, human H1N1 viruses had acquired additional N-linked glycosylation (NLG) sites within the globular head region of hemagglutinin (HA) until the NLG-free HA head pattern of the 1918 H1N1 virus was renewed with the swine-derived 2009 pandemic H1N1 virus.(More)
OBJECTIVE Emphysematous pyelonephritis (EPN) is an acute necrotizing infection of the kidney characterized by gas formation. In order to compare the outcome of nephrectomy and kidney-preserving procedures for the treatment of EPN we reviewed our experiences of EPN over the past 18 years. MATERIAL AND METHODS The medical records of 17 patients with EPN(More)
Flux balance analysis (FBA) in combination with the decomposition of metabolic networks into elementary modes has provided a route to modeling cellular metabolism. It is dependent, however, on the availability of external fluxes such as substrate uptake or growth rate before estimates can become available of intracellular fluxes. The framework classically(More)
Inflammatory myofibroblastic tumor (IMT) is an uncommon mesenchymal solid tumor commonly documented in children and young adults. Here, we report a case of IMT in colon confirmed pathologically after laparoscopic anterior resection. A 35-year-old man presented with anal bleeding after defecation for 2 weeks. Colonoscopy demonstrated a mass with shallow(More)
