OBJECTIVE Epidemiological studies have demonstrated that excess weight increases the risk of thyroid cancer. However, the associations between excess weight and prognostic factors for thyroid cancer are uncertain. We evaluated the relationships between body mass index (BMI) and clinico-pathological features and outcomes of papillary thyroid cancer (PTC). (More)
We tested the correlation between diabetes and aggressiveness of colorectal polyps in diabetic patients and matched non-diabetic controls. We retrospectively studied 3,505 type 2 diabetes (T2DM) patients without gastrointestinal symptoms who underwent colonoscopy for colorectal cancer at Samsung Medical Center, Seoul, Korea from August 1995 to August 2009.(More)
BACKGROUND/AIMS We investigated the clinical characteristics and follow-up findings of subjects with adrenal incidentalomas in a single, tertiary-care hospital in South Korea. METHODS The study consisted of a retrospective analysis of 282 adrenal incidentaloma patients who underwent radiographic and endocrinological evaluations at Samsung Medical Center(More)
BACKGROUND We evaluated the association of regular physical exercise with the presence of non-alcoholic fatty liver disease (NAFLD) and liver enzymes in relation to obesity and insulin resistance. METHODOLOGY/PRINCIPAL FINDINGS A cross-sectional analysis was conducted in 72,359 healthy Korean adults without diabetes who participated in a comprehensive(More)
It has not yet been determined whether chronic exposure to relatively low doses of pioglitazone increases risk of bladder cancer. We aimed to assess the risk of bladder cancer associated with pioglitazone in Korean patients. This was a retrospective cohort study of diabetic patients who had ≥ 2 clinic visits between November 2005 and June 2011 at one of(More)
BACKGROUND & AIMS Most studies on the role of STAMP2 in metabolism have used adipose tissue. Little knowledge exists concerning the role of STAMP2 in the liver, which is a metabolically central target. We hypothesized that STAMP2 is involved in non-alcoholic fatty liver disease (NAFLD) pathogenesis. METHODS We examined our hypothesis using human NAFLD(More)
BACKGROUND The ratio of apolipoprotein B (apoB) to apolipoprotein A1 (apoA1) has been reported to be associated with metabolic syndrome (MetS) and insulin resistance (IR). Non-HDL-C is regarded as a surrogate marker for apoB in routine clinical practice. However, it is unclear whether the ratio of non-HDL-C to HDL-C is an equal or a better predictor than(More)
There has been a rapid increase in the prevalence of obesity, type 2 diabetes and metabolic syndrome(MetS) over the past two to three decades in most Asian countries. According to the Korean National Health and Nutrition Examination Survey(KNHANES), the prevalence of MetS significantly increased from 24.9% to 31.3% between 1998 and 2007. The clinical(More)
We aimed to evaluate the diagnostic performance of measuring the concentration of thyroglobulin (Tg) in the washout fluid of the needle aspiration (FNA-Tg). We performed a systematic search of MEDLINE (inception to October 2013) and EMBASE (inception to October 2013) for English publications using keywords "thyroid", "aspiration", "washout", and(More)
BACKGROUND Primary hypophysitis causes varying degrees of endocrine dysfunction and mass effect. The natural course and best treatment have not been well established. METHODS Medical records of 22 patients who had been diagnosed with primary hypophysitis between January 2001 and March 2013 were retrospectively reviewed. Based on the anatomical location,(More)
