Background

To evaluate the association between serum 25-hydroxyvitamin D (25(OH)D) at mid-pregnancy and postpartum glucose intolerance in women with gestational diabetes mellitus (GDM).

Methods

We enrolled 348 pregnant women diagnosed with GDM from August 2012 to October 2016. We measured serum 25(OH)D levels at mid-pregnancy and carried out a 75-g oral glucose tolerance test at 6 to 12 weeks after delivery. Vitamin D deficiency was defined as serum 25(OH)D <20 ng/mL.

Results

The prevalence of vitamin D deficiency was 76.7% (n=267). Women with vitamin D deficiency had a higher prevalence of postpartum glucose intolerance than did those without vitamin D deficiency (48.7% vs. 32.1%, P=0.011). Serum 25(OH)D level was negatively correlated with hemoglobin A1c at antepartum and postpartum period (antepartum: r=−0.186, P=0.001; postpartum: r=−0.129, P=0.047). Homeostasis model assessment of β-cell function was positively correlated with serum 25(OH)D level only postpartum (r=0.138, P=0.035). The risk of postpartum glucose intolerance was 2.00 times (95% confidence interval, 1.13 to 3.55) higher in women with vitamin D deficiency than in those without vitamin D deficiency (P=0.018).

Conclusion

In women with GDM, vitamin D deficiency at mid-pregnancy is associated with an elevated risk of postpartum glucose intolerance.

Background

Epidemiological data is useful to estimate the necessary manpower and resources used for disease control and prevention of prevalent chronic diseases. We aimed to evaluate the incidence of diabetes and identify its trends based on the claims data from the National Health Insurance Service database over the last decade.

Methods

We extracted claims data on diabetes as the principal and first additional diagnoses of National Health Insurance from January 2003 to December 2012. We investigated the number of newly claimed subjects with diabetes codes, the number of claims and the demographic characteristics of this population.

Results

Total numbers of claimed cases and populations with diabetes continuously increased from 1,377,319 in 2003 to 2,571,067 by 2012. However, the annual number of newly claimed diabetic subjects decreased in the last decade. The total number of new claim patients with diabetes codes decreased as 30.9% over 2005 to 2009. Since 2009, the incidence of new diabetes claim patients has not experienced significant change. The 9-year average incidence rate was 0.98% and 1.01% in men and women, respectively. The data showed an increasing proportion of new diabetic subjects of younger age (<60 years) combined with a sharply decreasing proportion of subjects of older age (≥60 years).

Conclusion

There were increasing numbers of newly claimed subjects with diabetes codes of younger age over the last 10 years. This increasing number of diabetic patients will require management throughout their life courses because Korea is rapidly becoming an aging society.

Abstract PDF PubReader

Our aim was to examine whether serum testosterone concentrations are in fact low in hospitalized men with poorly controlled type 2 diabetes compared with healthy men. In this study, 79 men aged 40 years or older (41 healthy men and 38 men with type 2 diabetes) were included. Total testosterone and sex hormone-binding globulin levels were measured. The average duration of diagnosed diabetes was 10.8 years and the mean glycated hemoglobin value was 10.8%. Total testosterone concentrations were lower in men with type 2 diabetes than in healthy men, after adjusting for age and body mass index (3.83±0.32 ng/mL vs. 5.63±0.31 ng/mL, P<0.001). In conclusion, this study shows that serum testosterone concentrations are lower in hospitalized men with poorly controlled type 2 diabetes than in healthy men. Therefore, men with poorly controlled type 2 diabetes should undergo further assessment for hypogonadism.

Abstract PDF: Syndrome of inappropriate antidiuretic hormone is the most common cause of hyponatremia in hospitalized patients. It is defined as retention of water, loss of sodium and inappropriately concentrated urine in euvolemic patients with normal renal and adrenal function. A 26-year old male was admitted due to weight loss and fever that he had experienced for the previous 1 month. The chest X-ray and CT scan of lung showed about 2.5x1.2 cm lymph node enlargement at the left hilum and multiple lymph node enlargements. Thoracoscopic biopsy revealed tuberculosis. During treatment with antituberculosis drugs, the serum sodium was 125 mEq/L, the serum osmolality was 263 mOsm/kg, the urine osmolality was 577 mOsm/kg, and the urine sodium concentration was 177 mEq/L. He was treated by fluid restriction and hypertonic saline infusion, but he did not improve. Brain CT scan showed tuberculous meningitis with hydrocephalus. He fully recovered after undergoing ventriculoperitoneal shunt. We report here on a case of inappropriate antidiuretic hormone syndrome complicated by tuberculous meningitis that was refractory to antituberculosis drugs.

Abstract PDF

BACKGROUND
Common carotid artery intima-media thickness (IMT), which is increased in patients with overt hypothyroidism, is an independent risk factor of the atherosclerosis-related disease. This study was performed to compare serum lipid level and common carotid artery IMT among patients with overt hypothyroidism, subclinical hypothyroidism and euthyroidism. METHODS: Patients with newly-diagnosed subclinical (n=32) and overt (n=32) hypothyroidism were selected for this study. All of the patients and an age- and sex-matched euthyroidism cohort were checked for clinical characteristics and serum lipid levels. Common carotid artery IMT was also measured using high resolution B-mode ultrasonography. RESULTS: Statistically significant differences were observed between the total cholesterol levels of patients with subclinical hypothyroidism and those with euthyroidism. When common carotid artery IMT measured by ultrasonography, subclinical (0.67 +/- 0.11 mm) and overt (0.71 +/- 0.12 mm)) hypothyroidism showed significantly increased mean IMT compared to that of euthyroidism (0.58 +/- 0.07 mm, P < 0.05, respectively), but no differences were found between subclinical and overt hypothyroidism. CONCLUSION: We concluded that subclinical hypothyroidism is related to increased common carotid artery IMT as well as dyslipidemia. Therefore, we recommend that treatment principle of subclinical hypothyroidism be established through large-scale, prospective studies performed to determine the effect of thyroid hormone replacement on the reduction of common carotid artery IMT.

Abstract PDF

Mesenchymal tumors including hemangiopericytomas, hepatocellular tumors, adrenal carcinomas, and a variety of other large tumors have been reported to produce excessive amounts of insulin-like growth factor (IGF) type II precursor, which binds weakly to insulin receptors and strongly to IGF-I receptors, leading to insulin like actions. In addition to increased IGF-II production, IGF-II bioavailability is increased due to complex alterations in circulating binding proteins. The authors of this article diagnosed non-islet cell tumor hypoglycemia from an 81-year-old male patient suffering from repetitive fasting hypoglycemia while he has not received any treatment for pulmonary hemangiopericytoma diagnosed in the past. Moreover, this topic is getting reported as the authors have experienced a significant improvement of catamnesis by a treatment with glucocorticoid.

Abstract PDF

BACKGROUND
There have been recent reports that the fat distribution within skeletal muscle and the amount of muscle mass are associated with insulin resistance and the development of type 2 diabetes mellitus (T2DM). This study evaluated the impacts of visceral fat and thigh muscle from patients with T2DM and healthy subjects on atherosclerosis and insulin resistance. METHODS: Forty-two patients with newly-developed T2DM and 11 healthy subjects were selected for the study. The diabetic patients were subdivided into two groups, those under 40 years of age, as the young T2DM (n=21) group, and 40 years-old or greater, as the old T2DM (n=21) group. CT scans were obtained for all patients at the L4-L5 level and at the mid-portion between the greater trochanter and upper margin patella. The carotid intima-media thickness (IMT) was also measured using high resolution B-mode ultrasonography. RESULTS: The mean visceral fat area (VFA) in the old T2DM group was 169.4+/-13.2cm2, which was significantly greater than that found in the healthy subjects (67.9+/-7.92cm2, P<0.001) and young T2DM group (127.1+/-10.4cm2, P<0.05). The mean visceral fat to normal density muscle area ratio (VMNR) in the old T2DM group was 1.50+/-0.19, which was greater than in the healthy subjects (0.46+/-0.52, P<0.001) and young T2DM group (1.01+/-0.10, P<0.05). The total thigh muscle areas in the young and old T2DM groups were smaller than that in the healthy subjects, but without statistical significance. VMNR showed a positive correlation with the IMT and HOMA-IR. However, the total thigh muscle area was negatively correlated with the IMT. The normal density muscle area also showed significant negative correlations with the IMT and HOMA-IR. In a multiple regression analysis, age and VMNR were the most important independent risk factors of an increased carotid IMT. CONCLUSION: This study showed that the role of thigh muscle, as well as that of visceral fat, played a very important role in the occurrence of atherosclerosis. VMNR was found to be an especially important independent factor for an increased carotid IMT.

Abstract PDF: An increasing number of incidental adrenal masses are found during the evaluation for unrelated problems, which is the result of the development of sensitive noninvasive methods for the imaging of abdominal lesions, such as ultrasonography, computed tomographic scanning, and MRI. When there is no evidence of adrenocortical or medullary dysfunction for such adrenal masses, they are commonly referred to as "incidentalomas". Among these incidentalomas, adrenal myelolipoma is a rare, benign, endocrinologically inactive tumor, the histological structure of which consists of mature adipose tissue cells and normal hemopoietic tissues resembling bone marrow. Even though most eventually prove to be nonhyperfunctioning adrenocortical adenomas, we must not exclude a more serious pathology. Because of the rarity of adrenal myelolipoma, its natural history, proper prognostic considerations and treatment recommendations still need to be investigated. We experienced 46 year-old man with abdominal discomfort, and a 26 year-old man with no specific symptoms, have large incidentalomas (>5 cm) in adrenal sites, detected by abdominal sonography for routine health work-up. The ACTH, cortisol, renin, aldosterenone, metanephrine, VMA and tumor marker levels were normal, which was suggestive of nonfunctional adrenal tumors. Surgical treatments were performed for rule out malignant adrenal tumors due to the tumor size (>5 cm) and hemorrhage within the tumors. The surgical pathology was that of adrenal myelolipomas. An adrenal myelolipoma is a rare, benign, nonfunctional adrenal tumor, but only three cases have been reported in Korea. We report two cases of adrenal myelolipoma found incidentally by surgical treatment for a large tumor size (>5 cm).

Abstract PDF: Granulocytopenia, which can be seen in patients with Graves' disease during treatment with antithyroid agents, could be a self resolving transient episode or can imply the beginning of life threatening agranulocytosis requiring a change in treatment modality. Transient granulocytopenia could be a manifestation of hyperthyroidism itself, or a mild side effect of antithyroid drugs. Aganulocytosis is a rare, but major complications of the termination drug, propylthiouracil (PTU), requiring prompt termination of the medication, and intensive care. Therefore, differentiation of agranulocytosis and transient granulocytopenia, is important, but is not practically easy. We introduce a case of transient granulocytopenia, which was detected in a patient with Graves'Disease, accompanied by underlying type 1 diabetes mellitus, during treatment with PTU. Diagnosis of transient granulocytopenia was made by a normal granulocyte count following a single injection of G-SCF, and the patient was treated with conservative therapy. This case confirms a diagnostic tool for differentiating transient granulocytopenia and PTU-induced agranulocytosis.

Abstract PDF: We report a point mutation in the TRbeta gene in korean patients with generalized resistance and pituitary resistance to thyroid hormone. One mutation at TRbeta (P453S) were detected in patient with pituitary resistance to thyroid, which showed different phenotype, generalized resistance to thyroid hormone, in her mothers. But, the other (C31Y), did not show clear relations with the disease. Therefore, further study of molecular and cellular basis will be warranted to explain the clear mechanism of the resistance to thyroid hormone.

Abstract PDF: Although calcification of such endocrine gland as adrenal or pineal gland is common, extensive calcification of the pituitary gland is unusual. Calcification is a well recognized but uncommon feature of prolactin-secreting, growth hormone-secreting and non-functioning pituitary tumours. The calcification varies in extent, but rarely exceeds a tiny amount histologically or radiologically. Recently, we had the opportunity to investigate two patients with radiologically demonstrated "pituitary stone" (severely calcified pituitary adenoma). The first Patient, a 51 year-old female, initially presented with general weakness, dizziness, visual disturbance, and loss of hair for 2 months. She was suspected to have a pituitary lesion. Decreased secretion of GH, TSH, LH, and FSH was demonstrated by dynamic tests. On CT scan, she was found to have multilobulated calcified sella mass. She was successfully managed by medical treatment. The second patient, a 65 year-old male, presented with general weakness, nausea, vomiting and polyuria for 2 months. Combined pituitary stimulation test showed subnormal response of GH and prolactine. Radiologic studies revealed pituitary stone which was managed with medical treatment of hormone replacement. We suggest that calcific changes in the pituitary adenoma might be common and occur to the extent of pituitary stone formation with the possible alteration of hormonal secretion.

Abstract PDF: Primary aldosteronism, not a common cause of high blood pressure, is a syndrome which results from excessively secreted aldosterone from adrenal gland and it accounts for 0.05-2.2% of unselected hypertension. In this case the lesion was not visualized on routine abdominal computed tomographic scan due to its small size. Therefore the selective adrenal venous catherterization & venous sampling was done. As there is some difficulty of sampling from Rt. adrenal vein, the method of measuring aldosterone vs. cortisol ratio of Lt. adrenal vein and inferior vena cava was used to localize the aldosterone-producing adenoma. Clinical symptoms normalized and laboratory data returned to normal range after the surgical adrenalectomy.

Abstract PDF: BACKGROUND
Recently, missense mutation of the B3-adrenergic receptor gene has been shown to be associated with early onset of type 2 diabetes, abdominal obesity and an increased capacity to gain weight. This study was performed to investigate the effects of Trp64Arg mutation in the B3-adrenergic receptor gene on body fat distribution and weight loss in obese subjects. METHODS: Determination of the B3-adrenergic receptor gene mutation with restriction enzyme digestion method, anthropometry, various biochemical studies, including oral glucose tolerance test were performed in 99 obese and 35 control subjects. Body fat distributions were also evaluated by computerized tomography before and after weight-reduction program. RESULTS: I) There were no differences in the frequencies of Trp64Arg mutation in the B3-adrenergic receptor gene between obese and control subjects (15.2 vs 12.9 %). 2) The obese subjects with Trp64Arg mutation had higher waist to hip circumference ratio(WHR) (0.93 +/- 0.05 vs 0.87 +/- 0.04, p<0.001), visceral fat area (115.0 +/- 25.9 vs 86.4 +/- 41.4 cm, p=0.01), but decreased plasma free fatty acid (618.0 +/- 163.1 vs 817.5 +/- 248.2 pEq/L, p=0.001), and triglyceride level (118.7 +/- 36.2 vs 158.4 +/- 105.8 mg/dL, p=0.015) than those without mutation. 3) The obese subjects with Trp64Arg mutation had smaller decreases in weight (-3.4 vs -5.1 kg, p<0.001), body fat content (-2.1 vs -3.8 %, p<0.001), WHR (-0.01 vs -0.03, p=0.025), and abdominal fat masses (total, subcutaneous, and visceral fat) after weight-reduction program than those without mutation. CONCLUSION: Trp64Arg mutation in the B3-adrenergic receptor gene might be one of genetic loci contributing to central obesity and a predictor of difficulty in losing weight in obese subjects.
