The Clinical Meaning of Benign Colon Uptake in (18)F-FDG PET: Comparison with Colonoscopic Findings.

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 subjects who had undergone FDG-PET, 43 subjects who were diagnosed to have benign colon uptake in FDG-PET and underwent colonoscopy were retrospectively reviewed.

[Clinicopathological characteristics of gastric cancer and survival improvement by surgical treatment in the elderly].

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.

A more appropriate cardiac troponin T level that can predict outcomes in end-stage renal disease patients with acute coronary syndrome.

Purpose: Cardiac troponin T (cTnT), a useful marker for diagnosing acute myocardial infarction (AMI) in the general population, is significantly higher than the usual cut-off value in many end-stage renal disease (ESRD) patients without clinically apparent evidence of AMI. The aim of this study was to evaluate the clinical usefulness of cTnT in ESRD patients with acute coronary syndrome (ACS).

Materials And Methods: Two hundred eighty-four ESRD patients with ACS were enrolled between March 2002 and February 2008.
