RESUMO
The Korean Society for the Study of Obesity (KSSO) has defined the waist circumference cutoff value of central obesity as 90 cm for men and 85 cm for women. The purpose of this investigation was to determine the corresponding waist circumference values. A total of 3,508 persons in the Korean Rural Genomic Cohort Study were enrolled in this survey. Receiver operating characteristic (ROC) curve analysis was used to find appropriate waist circumference cutoff values in relation to insulin resistance determined by homeostasis model assessment for insulin resistance (HOMA-IR), body mass index (BMI), and components of metabolic syndrome. The optimal waist circumference cutoff values were 87 cm for men and 83 cm for women by ROC analysis to HOMA-IR and 86 cm for men and 83 cm for women by ROC analysis to value with more than two components of metaobolic syndrome. By using a BMI > or =25 kg/m2, 86 cm for men and 82 cm for women were optimal waist circumference cutoff values. In this study, we suggest that the most reasonable waist circumference cutoff values are 86-87 cm for men and 82-83 cm for women.

BACKGROUND: Postmenopausal status is associated with a 60% increased risk for metabolic syndrome. It is thought to be associated with decreased estrogens and increased abdominal obesity in postmenopausal women with metabolic syndrome. The purpose of this study was to investigate the association between metabolic syndrome components and menopausal status. METHODS: A total of 1,926 women were studied and divided into three groups according to their menstrual stage (premenopausal, perimenopausal or postmenopausal). The presence of metabolic syndrome was assessed using the National Cholesterol Education Program's (NCEP) Adult Treatment Panel III criteria. RESULTS: The prevalence of metabolic syndrome was 7.1% in premenopause, 9.8% in perimenopause, and 24.2% in postmenopause. The strong correlation was noted between the metabolic syndrome score and waist circumference in postmenopause (r = 0.56, P < 0.01) and perimenopause (r = 0.60, P < 0.01). Along the menopausal transition, the risk of metabolic syndrome increased with high triglyceride after the age-adjusted (odds ratio (OR) 1.517 [95% confidence interval (CI) 1.014~2.269] in perimenopausal women and OR 1.573 [95% CI 1.025~2.414] in postmenopausal women). In addition, the prevalence of metabolic syndromeincreased in accordance with elevated alanine aminotransferase (ALT) and gamma-glutamyl transpeptidase (GGT) levels. CONCLUSION: Triglyceride and waist circumference were important metabolic syndrome components, though ALT and GGT may also be related for predicting metabolic syndrome during the transition to menopause.

PURPOSE: The short insulin tolerance test is a simple and reliable method of estimating insulin sensitivity. This study was designed to compare the insulin sensitizing effects of thiazolidinediones (TZDs) on the degree of insulin resistance, determined by a short insulin tolerance test (Kitt) in type 2 diabetic patients. PATIENTS AND METHODS: Eighty-three subjects (mean age = 57.87 +/- 10.78) with type 2 diabetes mellitus were enrolled and received daily one dose of rosiglitazone (4mg) or pioglitazone (15mg). The mean follow-up duration was 25.39 +/- 9.66 months. We assessed insulin sensitivity using HOMA-IR and the short insulin tolerance test before and after TZDs treatment. RESULTS: When we compared patients' characteristics before and after TZDs treatment, the mean fasting glucose level was significantly decreased (183.27 +/- 55.04 to 137.35 +/- 36.42mg/dL, p or = 2.5%/min; 3.50 +/- 0.75%/min to 2.75 +/- 1.12%/min, p = 0.002). CONCLUSION: The glucose lowering effects of TZDs by improving insulin resistance could be determined by using Kitt. However, Kitt may be a beneficial tool to determine TZDs' effects only when patients' Kitt values are less than 2.5%/min.

Mycoplasma pneumoniae (M. pneumoniae) is the leading cause of pneumonia in older children and young adults. Normally, it does not progress to a condition requiring hospitalization but improves spontaneously or has a mild clinical course. We report two cases of M. pneumoniae pneumonia with different clinical manifestations from the normal course. The patients were young healthy individuals. The diagnoses were made by serology. However, it could not be determined beforehand that they had M. pneumoniae pneumonia. Based on the empirical treatment strategy of severe community acquired pneumonia, the patients were treated with broad-spectrum antibiotics including cephalosporin, quinolone and macrolide. After administering the antibiotics, they showed a gradually favorable clinical course and recovered without residual complications. A M. pneumoniae infection should be considered as a cause of severe community acquired pneumonia, and empirical treatment targeting this organism might be helpful in treating patients with the severe manifestation.

Systemic lupus erythematosus (SLE) is a chronic inflammatory disease of unknown cause, and is characterized by appearance of various autoantibodies and multiple organ involvement. Some of the systems commonly involved in SLE include the muscle and joints, brain and peripheral nervous system, lungs, heart, kidneys, skin, serous membranes, and component of blood. The clinical manifestations of SLE is protean, overlap with other illnesses, and are often subtle. However there are few documented reports on SLE associated with Crohn's disease in other countries and no reporting case in Korea. We experienced a 30-year-old female patient who was admitted for right leg swelling and diagnosed as SLE with Crohn's disease.
