Methicillin-resistant Staphylococcus aureus infection can be treated effectively by combining a β-lactam antibiotic with drug that targets FtsZ.
The aim of this study was to determine the accuracy endoscopic ultrasonography (EUS) and multidetector-row computed tomography (MDCT) for locoregional staging gastric cancer. EUS (CT) are valuable tools preoperative evaluation With introduction new therapeutic options recent improvements in CT technology, further diagnostic MDCT is needed.In total, 277 patients who underwent MDCT, followed by gastrectomy or resection at Bundang Hospital, Seoul National University, from July 2006 April 2008,...
Single-crystalline artificial AB-stacked bilayer graphene is formed by aligned transfer of two single-crystalline monolayers on a wafer-scale. The obtained has well-defined interface and electronically equivalent to exfoliated or direct-grown bilayers.
Abstract Background Sarcopenia or visceral adipose tissue has been reported to be related pancreatic cancer prognosis. However, clinical relevance of the comprehensive analysis body compositions and their longitudinal changes is lacking. This study analysed association between composition after chemotherapy survival in patients with metastatic cancer. Methods We retrospectively included 456 (mean age ± standard deviation, 61.2 10.0 years; 272 males 184 females) who received palliative from...
The objective of this study was to compare the efficacy and procedure time ultrasound-guided fine-needle aspiration biopsy (US-FNAB) thyroid nodules, according nodule size.US-FNABs nodules performed between June 2007 December were studied. We divided these patients into three groups largest diameter their nodules. Group A consisted with less than or equal 5 mm, group B greater mm 10 C mm. retrospectively reviewed cytopathology results complications in all patient measured separate, total...
Abstract Background: The eradication rate of first‐line Helicobacter pylori treatment is only 70–85% and has been decreasing due to the increase in antibiotic resistance. aim this study was evaluate efficacy bismuth‐containing quadruple therapy as second‐line for H. infection based on duration. Methods: We prospectively enrolled 227 patients that were found have persistent after proton‐pump inhibitor‐clarithromycin‐amoxicillin triple therapy. Patients randomized 1‐week (112 patients) 2‐week...
Endoscopic intervention is considered to be the primary treatment for biliary stricture after adult living donor liver transplantation (LDLT) with duct-to-duct reconstruction. The aim of this study was investigate risk factors and clinical outcomes predictors failure endoscopic retrograde cholangiography balloon dilation (ERC-D). We enrolled 239 patients who underwent LDLT between 2000 2006. Sixty-eight (28.4%) developed stricture. Twenty-nine anastomotic were treated ERC-D stenting....
Abstract Background A consensus conference has recommended close observation of branch duct intraductal papillary mucinous neoplasms (BD-IPMNs) smaller than 30 mm, without symptoms or mural nodules. This study investigated whether these recommendations could be validated in a single-centre experience BD-IPMNs. Methods Some 190 patients with radiological imaging histological findings consistent BD-IPMN were enrolled between 1998 and 2005. Those less 6 months' follow-up no confirmation...
Abstract Background The eradication rate with PPI ‐based standard triple therapy for Helicobacter pylori infection has fallen considerably. One recent innovation is sequential and three antibiotics, but the complexity of this regimen may reduce its usability. Concomitant administration nonbismuth quadruple drugs (concomitant therapy) also an effective treatment strategy. To investigate which a reasonable choice K orean population, we performed two pilot studies concomitant therapies. Methods...
Peripancreatic fluid collections (PFCs) have been adequately drained using multiple plastic stents placed in a single-step endoscopic ultrasound (EUS) procedure. Recent reports presented the usefulness of metal for this procedure; however, there has no prospective comparative study on their effectiveness and safety. We conducted randomized to compare with fully covered, self-expanding (FCSEMSs) drainage PFCs.Between January 2012 May 2013, patients PFCs demonstrated by various modalities were...
Abstract Background Liver function tests (LFTs) can be affected by many factors and the proposed effects of coffee on LFT require a comprehensive evaluation. The aim this study was to elucidate whether drinking coffee, smoking, or alcohol have independent LFTs in Korean health-check examinees. Methods We used responses 500 examinees, who had participated self-administered questionnaire survey about drinking, smoking habits. Results Coffee consumption closely related male gender, high body...

Gallbladder (GB) polyps are commonly encountered in clinical practice, and found more frequently as the number of medical screening examinations increases. The aim this study was to determine optimal practice guideline for surgical treatment follow-up GB polyps.Data from healthy subjects Seoul National University Hospital (SNUH) Health Care System Gangnam Center were used investigate true prevalence polyps. We also enrolled 689 patients with diagnosed at SNUH May 1(st), 1988 April 30(th),...
Objectives: Invasive intraductal papillary mucinous neoplasm (IPMN) of the pancreas is often considered to have a better prognosis than pancreatic ductal adenocarcinoma. The aim this study was evaluate and compare clinicopathologic features between 2 groups. Methods: Clinicopathologic long-term outcome 32 patients with invasive IPMN were retrospectively evaluated compared those 332 Results: Asymptomatic more frequently observed in group adenocarcinoma (28% vs 11%, P = 0.013). distribution...
We conducted this study to evaluate the efficacy of nonsurgical treatment for patients with infected pancreatic necrosis (IPN).Among 224 acute pancreatitis from 2000 2004, there were 31 diagnosed as having IPN complication. The diagnostic criteria either a positive culture or free gas in pancreas necrosis. Nonsurgical management including percutaneous drainage endoscopic (ED) followed by vigorous irrigation was initially attempted all patients. Surgery planned only when no clinical...
