Objective: Obesity is a well-known risk factor for type 2 diabetes, but few data exist on the association between weight changes and future diabetes risk in non-obese subjects. This study aimed to investigate the effect of weight changes on the incidence of type 2 diabetes in Korea, using prospective nationwide data.Research design and methods: A total of 51 405 non-diabetic subjects were included who had undergone health examinations in 2002 and complet...

Objectives: Considerable evidence shows that increased serum calcium levels are associated with metabolic disorders, cardiovascular disease and increased mortality. This study investigated whether serum calcium, within a normal range, is significantly associated with serum fibrinogen and homocysteine, markers of increased cardiovascular disease risk in non-diabetic Korean subjects.Methods: A cross-sectional analysis was performed on 1096 subjects (mean a...

Introduction: ACTH-producing pheochromocytoma has been rarely reported, ranging from 3 to 25% of the ectopic ACTH syndrome. Moreover, a few cases of Cushing’s syndrome (CS) accompanied with opportunistic infections have been reported. We experienced a case of pheochromocytoma with ectopic CS, complicated by invasive aspergillosis.Case report: A 35-year-old woman visited our hospital because of headache for 2 months. She presented with typical cushin...

Red blood cell (RBC) deformability is an ability of RBC to change shape under stress, and it has been known to be decreased in diabetes. However, the role of RBC deformability is not determined in type 2 diabetes (T2D) yet. We attempted to clarify whether RBC deformability is related with diabetic complications. This was a cross-sectional study, and 452 T2D patients were enrolled. RBC deformability was measured by using a microfluidic ektacytometer, Rheoscan-D (Rheo-Meditech, ...

Parathyroid carcinoma, a rare endocrine malignancy, accounting for only 1–2% of patients with primary hyperparathyroidism (HPT). In addition, a few case have been reported coexistence of parathyroid carcinoma and papillary thyroid cancer. Here, we present a case of recurred parathyroid cancer with multiple lymph node metastasis. A 57-year-old women was presented with high serum calcium level (14.4 mg/dl) in medical check-up. Hyperparathyroidism was considered to be the re...

Background: Gas-forming pyogenic liver abscess is an uncommon, life-threatening infection that is usually found in poorly-controlled diabetic patients. Here, we experienced a case of gas-forming pyogenic liver abscess in diabetes caused by Klebsiella pneumoniae.Clinical case: A 77-year-old man with 25-year history of diabetes was admitted due to fever for 2 days. On the physical examination, right upper quadrant tenderness of the abdomen was present. Ini...

Background: Depressive mood consequent to hypothyroidism can be reversed with levothyroxine (LT4) replacement therapy. However, it is unclear whether increasing LT4 dose confers additional mood benefits.Methods: This was a single-blind before-and-after study of 26 patients with hypothyroidism who were aged 65 years or older and undergoing LT4 replacement therapy. Geriatric Depression Scale (GDS-K) and Hyperthyroid Symptom Scale (HSS-K) were assessed at b...

Aim/hypotheses: Ectopic lipid accumulation in the heart contributes to the abnormal function of the heart and to the death of cardiomyocytes. Saturated FFA is one of the most important causes of death in cardiomyocytes. Although empagliflozin has been reported to be beneficial for people with diabetic complications and/or CVD, it has not been confirmed as to how it affects cardiomyocytes death by FFA. This study was designed to evaluate the protective effects of SGLT2 inhibito...

Aim: An international expert committee, after considering data on association of HbA1c and retinopathy, recommended that diabetes be diagnosed when HbA1c is more than 48 mmol/mol (>6.5%), provided this assay is done in a standardized laboratory. However, the performance of HbA1c in detecting diabetes in the Korean population remains unknown. The purpose of this study was to evaluate the efficiency of HbA1c in diagnosing diabetes and to identify the optimal threshold in the...

Background: TSH suppression therapy has been associated with hip and vertebral fracture. However, the relationship between TSH suppression and bone mineral density (BMD) remains controversial. The aim of this study was to evaluate the effect of TSH suppression therapy on cortical bone geometry in differentiated thyroid cancer (DTC) patients.Methods: This study included 122 subjects (19 men, 27 premenopausal women, and 75 postmenopausal women) who have be...
