Abstract PDF PubReader ePub: Background
Atherogenic dyslipidemia, which is frequently associated with type 2 diabetes (T2D) and insulin resistance, contributes to the development of vascular complications. Statin therapy is the primary approach to dyslipidemia management in T2D, however, the role of non-statin therapy remains unclear. Ezetimibe reduces cholesterol burden by inhibiting intestinal cholesterol absorption. Fibrates lower triglyceride levels and increase high-density lipoprotein cholesterol (HDL-C) levels via peroxisome proliferator- activated receptor alpha agonism. Therefore, when combined, these drugs effectively lower non-HDL-C levels. Despite this, few clinical trials have specifically targeted non-HDL-C, and the efficacy of triple combination therapies, including statins, ezetimibe, and fibrates, has yet to be determined.
Methods
This is a multicenter, prospective, randomized, open-label, active-comparator controlled trial involving 3,958 eligible participants with T2D, cardiovascular risk factors, and elevated non-HDL-C (≥100 mg/dL). Participants, already on moderate-intensity statins, will be randomly assigned to either Ezefeno (ezetimibe/fenofibrate) addition or statin dose-escalation. The primary end point is the development of a composite of major adverse cardiovascular and diabetic microvascular events over 48 months.
Conclusion
This trial aims to assess whether combining statins, ezetimibe, and fenofibrate is as effective as, or possibly superior to, statin monotherapy intensification in lowering cardiovascular and microvascular disease risk for patients with T2D. This could propose a novel therapeutic approach for managing dyslipidemia in T2D.

Background
Shift work is associated with obesity and metabolic syndrome. However, this association in the normal-weight population remains unclear. This study aimed to investigate whether shift work is associated with normal-weight obesity (NWO).
Methods
From the nationally representative Korea National Health and Nutrition Examination Survey (KNHANES) dataset (2008 to 2011), 3,800 full-time workers aged ≥19 years with a body mass index (BMI) ≤25 kg/m² were analysed. We defined NWO as BMI ≤25 kg/m² and body fat percentage ≥25% in men and ≥37% in women. Working patterns were classified into “daytime,” “other than daytime,” and “shift.” Multivariable logistic regression analysis was performed to evaluate the relationship between shift work and NWO.
Results
Shift work was associated with higher odds of NWO than daytime work (adjusted odds ratio [aOR], 1.47; 95% confidence interval [CI], 1.04 to 2.09) and night/evening work (aOR, 1.87; 95% CI, 1.11 to 3.14) after adjustment for type of work, working hours, age, sex, BMI, 25-hydroxyvitamin D levels, homeostatic model assessment for insulin resistance, and other sociodemographic factors. In subgroup analyses, the association between shift work and NWO was more robust in those aged ≥60 years and those working ≥56 hours/week.
Conclusion
Shift work was associated with NWO in community-dwelling Korean adults, independent of age, sex, BMI, and other covariates.

Background

This study investigated the overall status of diabetes control and screening for diabetic microvascular complications in patients with type 2 diabetes mellitus attending primary care clinics in Korea.

Methods

In this cross-sectional observational study, 191 primary care clinics were randomly selected across Korea from 2015 to 2016. In total, 3,227 subjects were enrolled in the study.

Results

The patients followed at the primary care clinics were relatively young, with a mean age of 61.4±11.7 years, and had a relatively short duration of diabetes (mean duration, 7.6±6.5 years). Approximately 14% of subjects had diabetic microvascular complications. However, the patients treated at the primary care clinics had suboptimal control of hemoglobin A1c levels, blood pressure, and serum lipid levels, along with a metabolic target achievement rate of 5.9% according to the Korean Diabetes Association guidelines. The screening rates for diabetic nephropathy, retinopathy, and neuropathy within the past 12 months were 28.4%, 23.3%, and 13.3%, respectively.

Conclusion

The overall status of diabetes management, including the frequency of screening for microvascular complications, was suboptimal in the primary care clinics. More efforts should be made and more resources need to be allocated for primary care physicians to promote adequate healthcare delivery, which would result in stricter diabetes control and improved management of diabetic complications.

Background

Recently, the triglyceride glucose (TyG) index has been considered a surrogate marker of insulin resistance which is a well-known pathogenic factor in nonalcoholic fatty liver disease (NAFLD). However, few studies have investigated the relationship between the TyG index and NAFLD. Thus, we investigated the relationship between the TyG index and NAFLD and the effectiveness of the TyG index compared with the homeostasis model assessment of insulin resistance (HOMA-IR) in identifying NAFLD in Korean adults.

Methods

Participants of 4,986 who underwent ultrasonography in a health promotion center were enrolled. The TyG index was calculated as ln [fasting triglycerides (mg/dL)×fasting glucose (mg/dL)/2], and HOMA-IR was estimated. NAFLD was diagnosed by ultrasonography.

Results

Significant differences were observed in metabolic parameters among the quartiles of the TyG index. The prevalence of NAFLD significantly increased with increment in the TyG index. After adjusting for multiple risk factors, a logistic regression analysis was performed. When the highest and lowest quartiles of the TyG index and HOMA-IR were compared, the odds ratios for the prevalence of NAFLD were 2.94 and 1.93 (95% confidence interval, 2.32 to 3.72 and 1.43 to 2.61; both P for trend <0.01), respectively. According to the receiver operating characteristic analysis, the TyG index was superior to HOMA-IR in predicting NAFLD.

Conclusion

The TyG index and prevalence of NAFLD were significantly related and the TyG index was superior to HOMA-IR in predicting NAFLD in Korean adults.

Background

Genetic variations in calpain-10 and adiponectin gene are known to influence insulin secretion and resistance in type 2 diabetes mellitus. Recently, several single nucleotide polymorphisms (SNPs) in calpain-10 and adiponectin gene have been reported to be associated with type 2 diabetes and various metabolic derangements. We investigated the associations between specific calpain-10 and adiponectin gene polymorphisms and Korean type 2 diabetes patients.

Methods

Overall, 249 type 2 diabetes patients and 131 non-diabetic control subjects were enrolled in this study. All the subjects were genotyped for SNP-43 and -63 of calpain-10 gene and G276T and T45G frequencies of the adiponectin gene. The clinical characteristics and measure of glucose metabolism were compared within these genotypes.

Results

Among calpain-10 polymorphisms, SNP-63 T/T were more frequent in diabetes patients, and single SNP-63 increases the susceptibility to type 2 diabetes. However, SNP-43 in calpain-10 and T45G and intron G276T in adiponectin gene were not significantly associated with diabetes, insulin resistance, nor insulin secretion.

Conclusion

Variations in calpain-10, SNP-63 seems to increase the susceptibility to type 2 diabetes in Koreans while SNP-43 and adiponectin SNP-45, -276 are not associated with impaired glucose metabolism.

Abstract PDF

BACKGROUND
17 beta-estradiol is known to play an important role in glucose homeostasis. Lipin-1 is a nuclear protein that is essential in adipocyte differentiation and it is considered to play a role in ectopic fat deposition and the redistribution of fat. The aim of this study was to evaluate the effect of 17 beta-estradiol on the lipin-1 expression in the adipocytes of OLETF rats, which is an animal model of diabetes. METHODS: The OLETF rats were divided into 3 groups, 1) the sham-operation group (SHAM) 2) the castrated group (CAST) and 2) the castrated and estradiol treatment group (EST), and all the rats were at 6 weeks of age. LETO rats were used as a control group (LETO). 0.1 mg of estradiol valerate was injected subcutaneously every 4 weeks in the rats of the EST group. The visceral and subcutaneous tissues were isolated to evaluate the lipin-1 protein expression. The lipin-1 expression was measured in human visceral and subcutaneous preadipocytes. RESULTS: Less body weight gain was observed in the EST group compared with that of the SHAM group. In addition, improvement in the glucose tolerance was observed in the EST group. The lipin-1 expression in visceral fat was decreased in the SHAM and CAST groups, but it was but recovered in the EST group. The lipin-1 expression in the subcutaneous fat was decreased in the SHAM, CAST, and EST groups. CONCLUSION: Long term estradiol treatment in OLETF rats reduces the body weight gain and improves the glucose tolerance. Estradiol enhances the lipin-1 protein expression in the visceral adipocytes, but not in the subcutaneous adipocytes.

Abstract PDF: Turner's syndrome is characterized by short stature and gonadal dysgenesis, and it is often associated with various systemic manifestations, such as cardiovascular, renal, thyroidal, gastrointestinal, and musculoskeletal disorders. Though very rare, it can also be accompanied by hypopituitarism. It is important to give a meticulous medical attention to short females with gonadal dysgenesis so that neither disease is neglected or gets delayed diagnosis. In this case, Turner's syndrome and hypopituitarism were diagnosed almost simultaneously, but hypopiuitarism was transient, and the normal pituitary function was recovered spontaneously without any treatment. Initial sella MRI showed mild congenital hypoplastic hypopituitarism, and combined pituitary function test was compatible with hypopituitarism, but after 5 years, though growth hormone deficiency was still present, otherwise normal pituitary function was noted without any change in MRI. Herein, we are reporting a case of Turner's syndrome with transient idiopathic hypopituitarism with the review of literature.

Abstract PDF: Fasting hypoglycemia results from several mechanisms. Autoimmune hypoglycemia is one of the rare causes of hypoglycemia, and characterized by hyperinsulinemia, fasting hypoglycemia and the presence of autoantibodies to insulin or insulin receptor. We report here on a 64-year-old male patient with autoimmune hypoglycemia with end stage renal disease. He had no history of diabetes or insulin use. He had experienced several severe hypoglycemic events. The serum C-peptide level was 7.48 ng/mL and the insulin concentration was 115.4 micro U/mL when the fasting plasma glucose level was 88 mg/dL. The insulin to glucose ratio was 5.42, which suggested the presence of insulinoma. Yet the radiologic studies, including magnetic resonance cholangiopancreatography, endoscopic ultrasonography and selective calcium stimulated venous sampling revealed no evidence of insulinoma. The insulin autoantibody level was 62 micro U/mL. Therefore, we could diagnosis the autoimmune hypoglycemia. The hypoglycemia was treated with prednisolone and the patient recovered from this. His insulin level decreased to 21.11 micro U/mL and the insulin autoantibody level decreased to 34 micro U/mL. Hypoglycemia in the hemodialysis patients is not uncommon. One should bear in mind autoimmune hypoglycemia as one of the causes of hypoglycemia in patients with no history of diabetes.

Abstract PDF

BACKGROUND
New onset diabetes is a major complication after kidney transplantation. However, the natural course of posttransplantation diabetes mellitus (PTDM) remains unclear. The aim of this study was to demonstrate the detailed natural courses of PTDM according to the onset and persistency of hyperglycemia, and to investigate risk factors for development of different courses of PTDM in renal allograft recipients. METHODS: A total of 77 renal allograft recipients without previously known diabetes were enrolled and performed a serial 75 g oral glucose tolerance test at 0, 1, and 7 years after kidney transplantation. Patients were classified according to the onset and persistency of PTDM: early PTMD (E-PTDM), late PTDM (L-PTDM), persistent PTDM (P-PTDM), transient PTMD (T-PTDM), and non-PTDN (N-PTDM). RESULTS: The incidence of each group was as follows: E-PTDM, 39%; L-PTDM, 11.7%; P-PTDM, 23.4% T-PTDM, 15.6%; N-PTDM, 49.3%. Tacrolimus and female gender were associated with the development of E-PTDM. Among E-PTDM, age at transplantation was a high risk factor for the development of P-PTDM. Higher BMI at year1 was associated with the development of L-PTDM. CONCLUSION: Different risk factors were associated with various natural courses of PTDM. Since old age and female gender are not modifiable risk factors, it may be important to modify immunosuppressive therapy regimens for the prevention of E-PTDM and control of body weight for L-PTDM.

Abstract PDF

BACKGROUND
Leptin has been suggested as a possible cause of atherosclerotic disease. The small dense low-density lipoprotein cholesterol (LDL-C) has also been regarded as a new surrogate marker in atherosclerotic disease. The aim of this study was to evaluate the relationship between the leptin concentration and the small dense LDL-C concentration in Korean type 2 diabetic patients. METHODS: One hundred-ninety one type 2 diabetic patients, who did not use any medication that could affect the concentration of lipid such as statin, fibrate, thiazolidinediones and corticosteroid, were enrolled in this study. We analyzed the relationship between leptin, the small dense LDL-C and the other metabolic parameters. RESULTS: The small dense LDL-C concentrations were higher in the group with the highest tertile of the leptin value, both in males and females than those patients in the group with the lowest tertile of the leptin value. The small dense LDL-C concentrations were also higher in the group with the highest tertile of leptin divided by the BMI value both in males and females than those patients in the group with the lowest tertile of the leptin value. The leptin concentration was positively correlated with the small dense LDL-C, total cholesterol, triglyceride, LDL-C, insulin and HOMAIR values after adjusting for age, gender and BMI. CONCLUSION: The association between leptin and small dense LDL-C could be a factor that explains the association between leptin and cardiovascular disease.

Abstract PDF: Opioids are known to decrease plasma cortisol and testosterone level in human and other mammals. Nowadays, opioid use is exponentially increasing, but little is known about its side effects. With the help of progressive human science, we can habit longer life and as result, are becoming more avid for healthy life. In this respect, analgesics play important role in maintaining good and healthy quality of life. For this reason, it is important to fully understand its side effects and handle it with special precaution. We are reporting a 22-year-old male who had been taken opioid analgesic for more than six years to relieve chronic, intractable headache. Then, his hormone test revealed hypogonadotropic hypogonadism combined with hypoadrenocorticotropic hypoadrenalism but showed no definite clinical features except for sexual frigidity. After two years of oxycodon discontinuation, we reevaluated that his hormone test, and all other laboratory tests returned to the normal range.

Abstract PDF: A 45-year-old woman who complained of weight gain and irregular menstruation was diagnosed as having Cushing's syndrome due to a 3 cm sized left adrenal adenoma. She underwent left adrenalectomy, and she also underwent combined anterior pituitary tests before and 9 months after the surgery. The growth hormone and adrenocorticotropic hormone levels failed to respond to hypoglycemia before the surgery, but their responses recovered after the surgery. Cortisol and thyroid stimulating hormone failed to respond to hypoglycemia and thyrotropin releasing hormone (TRH) before the surgery, respectively, but these were improved after the surgery. Luteinizing hormone, follicle stimulating hormone, and prolactin adequately responded to gonadotropin-releasing hormone and TRH, respectively, before and after the surgery. However, the basal levels of these hormones were higher after adrenalectomy, suggesting that hypercortisolemia had a significant influence on all the pituitary hormones.

This is the first report of papillary thyroid carcinoma combined with multiple endocrine neoplasia type 1 (MEN 1). It is an hereditary syndrome characterized by neoplastic disorders such as pituitary adenoma, parathyroid adenoma or hyperplasia and pancreatic neuroendocrine tumor, such as gastrinoma just like in our case. But sometimes pheochromocytoma, mucosal ganglioneuromas, lipoma, forgut carcinoid and thyroid disease could be accompany the disease, but coincidental papillary thyroid carcinoma was never reported before in Korea. Herein we represent a 39-year-old woman who manifested typical features of MEN 1 with coincidental papillary thyroid carcinoma. Despite with definite family history of MEN 1, her genetic analysis of DNA had not found any germline mutation in MEN 1 gene. Unidentified culprit gene unable further genetic study of finding LOH (loss of heterogeneity) in 11q13, the possible explanation of papillary thyroid carcinoma as a new component of MEN 1. As we have experienced a case of MEN 1 combined with papillary thyroid carcinoma, we report it with the review of literature.

Abstract PDF: Acromegaly is a clinical syndrome, which is caused by an excess of growth hormone (GH), most commonly secreted from a pituitary solitary adenoma. However, our patient had bilateral GH-secreting pituitary tumors, the incidence of which has been reported in only 1.3 to 1.69% of all acromegalic patients. A 59-year-old female, with no family history of pituitary adenomas, demonstrated an increased level of serum insulin-like growth factor-1 (IGF-1), and GH not suppressed after 75 g oral glucose loading. On a preoperative MRI, only one pituitary tumor, measuring 1.1 x 0.7 cm, could be observed using sellar MRI. After surgical resection of the tumor, her headache and myalgia were sustained, and the IGF-1 level was still in a high titer. Therefore, a follow-up sellar MRI was taken, and a 0.6 x 0.7 cm sized newly growing pituitary tumor was found on the other side. With a retrospective review of radiological examinations, the patient was found to have bilateral tumors. The 0.3 cm sized tumor on the left was too small to be detected on the preoperative MRI. As the patient preferred medical treatment after surgery, she was treated with sandostatin analogues. Acromegaly with bilateral GH-secreting pituitary tumors, is a very rare disease, with no previous case having been reported in Korea. Herein, we report the case with a review of the literature.

Abstract PDF: Acromegaly is a systemic endocrine disorder due to an excessive release of growth hormone, which increases the serum levels of insulin-like growth factor-1(IGF-1). Elevated levels of these hormones are assumed to increase the incidence of malignant tumors in patients with acromegaly, due to by stimulating the growth and maturation of cells. In particular, IGF-1 is considered to be closely related with the development of colon polyps and colon cancers. Studies suggest that various malignant tumors, including thyroid cancer, brain tumor and renal cell carcinomas, are also more common in patients with acromegaly. Here, a case of gall bladder cancer in a patient with acromegaly, and the possible relationships between these two disorders, is reported.

Abstract PDF

BACKGROUND
Anaplastic thyroid carcinoma represents 2% to 5% of all thyroid cancers and it is one of the most aggressive human cancers. Local extension at the time of diagnosis and distant metastases are almost always the rule. Its lethality is evidenced by a 5-year survival rate of 3.6% and a median survival time of 4 months. We retrospectively reviewed patients with this disease at 4 tertiary referral centers. METHODS: From 1990 to 2003, 19 cases(9 men and 10 women, mean age: 65.1+/-7.1 years) of anaplastic thyroid carcinoma were reviewed via the medical records. The overall survival rates according to the prognostic factors and the treatment modalities were analyzed. RESULTS: The presenting symptoms included rapidly enlarged neck masses in 16 patients, shortness of breath in 3 patients, hoarseness in 4 patients, dysphagia in 2 patients and chest wall pain in 1 patient. The mean diameter of tumor was 7.2cm. Local extension was seen in all of the cases that had undergone surgery. Distant metastases(lung 6, bone 2, abdominal carcinomatosis 2, brain 1 and mediastinum 1) were seen in 9 patients. Surgical treatment was performed in 10 patients. Radiotherapy was performed in 9 patients and chemotherapy was done in 5 patients; radiotherapy was performed alone in 2 patients, combination chemo-radiotherapy was performed in 3 patients, postoperative radiotherapy was performed in 2 patients and postoperative combination chemo-radiotherapy was performed in 2 patients. 4 patients were treated cons ervatively after the confirmative diagnosis. The overall median survival time was 123 days(range: 23~621 days); the median survival time was 129 days in the treatment group(n=15), and 27 days in the no treatment group (n=4), and significantly higher survival rates were observed for the treated patients(p=0.02). According to the treatment modalities, patients who underwent surgical treatment and postoperative radiotherapy and/or chemotherapy were observed to have significantly higher survival rates than patients in the radiotherapy and/or chemotherapy group(p=0.03), and also than those patients in the surgical treatment only group(p=0.04). CONCLUSION: We found that aggressive surgical treatment and postoperative radiotherapy and/or chemotherapy improved the survival rates of patients with anaplastic thyroid carcinoma even though local invasion and distant metastases was generally observed to occur

Abstract PDF

Multiple endocrine neoplasia type 1(MEN 1) is an autosomal dominantly inherited syndrome, characterized by the combined occurrence of tumors of the parathyroid glands, endocrine pancreas, and anterior pituitary gland. The MENIN gene, which is a kind of tumor suppressor gene, is located at the chromosomal locus 11q13. It consists of one untranslated exon and nine exons encoding the menin protein. We report a case of a 22-yearss-old woman with MEN type 1, who was proven to have a mutation in the MENIN gene. The patient was admitted because of repeated hypoglycemia. The fasting plasma glucose level was 32mg/dL. Seventy two hours fasting test showed an the insulin/glucose ratio as 0.33. Endoscopic ultrasonography detected multiple masses on the pancreas. The arterial -stimulated venous sampling(ASVS) with calcium showed sudden step up of insulin at the head and tail portions of the pancreas. The sellar MRI showed a pituitary mass that produced prolactin. Instead of a pathologic diagnosis from operational specimen, the genetic analysis revealed a mutation in the MENIN 1 gene(exon 2, 200~201insAGCCC).

Abstract PDF: BACKGROUND
The aim of this study was to examine the association between the common polymorphisms of the adiponectin gene(ACDC) and the intima-media thickness(IMT) of the common carotid arteries in type 2 diabetic patients. METHODS: The B mode ultrasound examination of carotid artery was performed on 133 type 2 diabetic patients. The carotid IMT was calculated using the Intimascope computer program. The SNP45 and SNP276 of the ACDC were examined. RESULTS: There was no significant difference in the carotid IMT among the SNP45 genotypes(0.66+/-0.18mm for TT, 0.71+/-0.12mm for TG and 0.64+/-0.15mm for GG, P=NS). Subjects carrying the SNP276 GG genotype had a markedly lower serum adiponectin concentration than those carrying the TT genotype(3.35+/-2.00microgram/mL vs. 4.98+/-2.24microgram/mL, P=0.029) The carotid IMT was significantly higher in patients with the SNP276 GG genotype than those with the TT genotype (0.70+/-0.17mm vs. 0.59+/-0.13mm, P=0.032). Patients with the +45GG/+276GG genotype combination showed significantly higher mean carotid IMT than the other genotype combinations(0.78+/-0.09mm vs. 0.71+/-0.15mm, P=0.013) CONCLUSIONS: These results suggest that the adiponectin gene, SNP276 is associated with the carotid IMT in type 2 diabetic patients. Further studies are will be needed to confirm these genotypephenotype associations.

Abstract PDF: Pendred syndrome is an autosomal recessive genetic disorder, which is characterized by sensorineural hearing loss, goiter and a positive perchlorate discharge test. It is caused by mutations of the PDS gene, and its clinical characteristics vary widely. The thyroid function in most cases is normal, or shows only mild hypothyroidism. In Pendred syndrome, there is an organification defect that leads to defective thyroid hormone synthesis, followed by chronic TSH stimulation. Herein is reported a case of a follicular thyroid carcinoma associated with Pendred syndrome. To our knowledge, this is the first case reported in Korea. The patient presented with a huge anterior neck mass, sensorineural hearing loss and a positive perchlorate discharge test. Fine needle aspiration cytology suggested malignancy of the thyroid, and a total thyroidectomy, with central compartment node dissection, was performed. The pathology from the thyroid mass showed a poorly differentiated follicular thyroid carcinoma

Abstract PDF: Diabetes mellitus is well known to be associated with various structural and functional liver abnormalities. If diabetic patients are accompanied by hepatomegaly or abnormal findings from a liver function test, the most common pathological findings are steatosis and glycogenosis. The steatosis is characterized by deposition of macrovesicular fat droplets in the hepatocytes, which is common in obese, type 2 diabetes mellitus. If macrovesicular steatosis is combined with mixed inflammatory infiltrate, without evidence of alcoholic hepatitis, the case could be diagnosed as nonalcoholic steatohepatitis (NASH). NASH has the possibility of progressing to cirrhosis. Secondary glycogenosis is common in uncontrolled type 1 diabetes mellitus, and is completely reversible. A 22-year-old male, with uncontrolled type 1 diabetes mellitus, was admitted with anorexia, nausea and right upper quadrant pain. Hepatomegaly and elevated aminotransferases were noted. He was diagnosed as diabetic glycogenosis using computed tomogram and liver biopsy. The hepato megaly and liver function test abnormalities were markedly improved with glycemic control

Abstract PDF: BACKGROUND
Adiponectin is an adipocytokine that is highly specific to adipose tissue. In contrast to other adipocytokine, the adiponectin levels are decreased in obesity and/or type 2 diabetes. There are few studies regarding the correlation between the adiponectin concentration and obesity in children. Thus, whether the serum adiponectin concentrations are associated with adiposity in children was investigated. METHODS: One hundred and sixty four subjects were selected from the participants in an ongoing study on the relationship between birth weight and insulin resistance in children. The current weights, heights, body fat percentages, waist circumferences, blood pressures, lipid profiles and insulin resistance, by the HOMA method, were measured in all the subjects. The serum adiponectin concentrations were determined by a validated sandwich ELISA, using a human adiponectin-specific antibody. RESULTS: The serum adiponectin concentration was negatively correlated with the body mass index, waist circumference, systolic blood pressure, insulin resistance by HOMA and serum triglycerides, and positively correlated with the serum HDL cholesterol level. The serum adiponectin concentrations in the boys were significantly lower than in the girls. In a multiple regression analysis, the serum adiponectin concentration was strongly associated with waist circumference and gender. CONCLUSION: It is concluded that there was an inverse relationship between the serum adiponectin concentration and abdominal adiposity in children. However, further studies on independent gender differences on adiponectin are needed.

Abstract PDF: Riedel's thyroiditis is a rare form of chronic thyroiditis, characterized by a fibroinflammatory process which partially destroys the thyroid, often involving surrounding tissues. The relationship of Riedel's thyroiditis to other forms of thyroiditis is not clear. A case of Riedel's thyroiditis in a 51-year-old female patient, admitted with a previous diagnosis of subacute thyroiditis, is reported. She was first diagnosed with subacute thyroiditis based on clinical manifestation and radiologic and laboratory results. She was treated with glucocorticoid for 8 weeks. The follow-up lasted for 12 months. However, three years later she underwent a thyroidectomy operation due to an enlargement of the thyroid nodule and suspicion of malignancy. Histopathologic examination confirmed that she had Riedel's Thyroiditis. Until now, few case of Riedel's thyroiditis in patients with a history of subacute thyroiditis have been reported in the literature. Although the etiology of Riedel's thyroiditis is unknown, it may develop in the course of subacute thyroiditis.

Abstract PDF: An adrenal cortical carcinoma is a rare malignancy associated with poor prognosis. On diagnosis, most patients present with large tumor masses, which are often detected at an advanced stage. The most effective treatment is a complete resection, which is the only curative treatment for adrenal cortical carcinomas. The most important prognostic factor is a successful resection of the primary tumor, as long as it is low-grade and has not spread to distant sites. However, with advanced adrenal cortical carcinomas, with distant metastasis, there is no strict effective treatment program, and the prognosis is poor. The case of a 50-year-old female patient, presenting with an adrenal cortical carcinoma and Cushing's syndrome, who had a long-term survival of 78 months, is reported. The mass was completely resected on diagnosis, but 16 months later liver metastasis was discovered. She had received chemotherapy, with cisplatin, etoposide and bleomycin, for the liver metastasis for a period of 15 months, but with no response, furthermore, the size had increased after 10 months. Afterward, she received her 10th session of intrahepatic artery cisplatin chemotherapy and her 3rd hepatic artery embolization. Although the patient had a large degree of liver metastasis, this was tolerated. The tumor mass is presently not aggravated, and she still survives after 78 months.

Abstract PDF: BACKGROUND
Leptin is known to affect bone metabolism both centrally and peripherally. This study was performed to investigate the relationship between leptin and bone mineral density(BMD) in healthy premenopausal and postmenopausal Korean women. METHODS: 140 women were recruited for a routine health check-up. Anthro-pometric and biochemical data were checked as usual. BMDs were measured by dual x-ray absorptiometry of the spine and femur in 67 premenopausal women and 73 postmenopausal women, in addition to their serum leptin levels. RESULTS: Serum leptin level showed no correlation with BMD in premenopausal women, but there was a positive correlation betwen serum leptin and spinal BMD in postmenopausal women(r=0.468, p<0.001). After the correcting for age, body mass index, and duration of menopause, the serum leptin level and BMD still showed a positive correlation(r=0.217, p=0.088) although weak. The women in the lowest quartile of serum leptin level showed significantly lower lumbar and femoral neck BMD. CONCLUSION: Leptin level seems to have a weak relationship with BMD showing different features in premenopausal and postmenopausal women.

Abstract PDF: BACKGROUND
Activation of the RET proto-oncogene, located on the long arms of chromosome 10, contributes to the development of thyroid cancers in two different ways. Somatic rearrangements of RET with variable genes of activation are frequently found in papillary thyroid carcinomas. And Ggerm-line point mutations are responsible for the development of medullary thyroid carcinoma and the multiple endocrine neoplasia type 2(MEN2). There are several conflicting reports on the influences of RET expression and RET/PTC rearrangements on the clinical outcome of thyroid cancer. Therefore, we performed an examination of RET expression and RET/PTC-1, -2, -3 rearrangements in papillary thyroid carcinomas and other thyroid diseases. METHODS: Twenty-six papillary thyroid carcinomas(PTCs), three follicular thyroid carcinomas (FTCs), one anaplastic thyroid carcinoma(ATC), five follicular adenomas(FAs), nineteen hyperplasias, and two normal thyroid tissues were included in this study. RT-PCR and immunohistochemistry analysis were done to identify RET gene, RET/PTC rearrangements, and ret RET protein expression. RESULTS: By RT-PCR, 89.4% of PTCs, 100% of FTCs, and 62.1% of hyperplasias expressed the RET gene, but no RET was observed in ATCs, FAs, and normal thyroid tissues. RET/PTC-1, -2,-3 rearrangements were not detected in any specimens. Immunohistochemical results revealed that 76.9% of PTCs, 50% of FAs, 52.3% of hyperplasias, and 20.6% of normal thyroid tissues expressed the RET ret protein, but FTCs and ATCs did not. Most PTCs showed strong cytoplasmic positivity in RET ret immunostaining, but the positive non- PTCs expressed weak and membranous staining. Overall, the two methods for detecting RET gene, RT-PCR and immunohistochemistry showed similar results. CONCLUSION: The RET gene was highly expressed in PTCs. In contrast to the previous reports of that theRET gene expression of RET gene is being limited to PTCs, RET was also expressed in hyperplasias, Fas, and normal thyroid tissues. However, the pattern and the degree of expression of the RET ret protein in non- PTCs were are different from those in PTCs.

Abstract PDF: Adrenocorticotropin (ACTH) independent bilateral macronodular adrenal hyperplasia (AIMAH) is a rare form of Cushing's syndrome, in which unique endocrinological, clinical and histopathological features have been described. In AIMAH, cortisol secretion is autonomous and independent of ACTH, thus plasma ACTH levels are persistently suppressed. Various etiological mechanisms have been proposed to explain the development of AIMAH, the development of aberrant adrenal sensitivity to gastric inhibitory polypeptide (GIP), vasopressin, beta-adrenergic receptor agonists or the presence of circulating adrenal stimulating immunoglobulins have been suggested. We report on a 46-year-old female who had Cushing's syndrome, due to AIMAH, with a positive response to vasopressin.

Abstract PDF: Klinefelter's syndrome is one of the most common forms of primary hypogonadism presenting with gynecomastia, azospermia and increased follicle-stimulating hormone. It is well known that this syndrome has an increased incidence of neoplasia, especially breast cancer and extragonadal germ cell tumors. However, it is rarely associated with an intracranial tumor of maldevelopmental origin, especially in the suprasellar area. We report, for the first time, a case of Klinefelter's syndrome, with a Rathke's cleft cyst is the patient was a 32-year-old male who was known to have an incidentaloma form brain computed tomography, which was clinically diagnosed as a suprasellar tumor. After operating, the suprasellar mass was confirmed as a Rathke's cleft cyst, and his hormonal abnormality, an elevated level of follicle-stimulating hormone, was not normalized. Therefore, we performed chromosomal analysis, and diagnosed Klinefelter's syndrome with the XXY karyotype.

Abstract PDF: BACKGROUND
Tibolone is a novel synthetic compound with tissue-specific effects in bone, breast tissue and the endometrium. Tibolone, and active vitamin D, effectively prevent bone loss, and the maintain skeletal integrity of postmenopausal women. The aim of the present study was to examine the effect of tibolone, and active vitamin D (1-hydroxyvitamin D3), therapies given alone, or in combination, against bone loss in postmenopausal women. METHODS: One hundred and three postmenopausal women were treated with tibolone (n=40), alphacalcidol (n=27) or both drugs (n=36) for 12 months. All subjects took supplemental calcium carbonate (500 mg daily). The bone mineral densities (BMD) of the lumbar spine and proximal femur were measured by dual-energy x-ray absorptiometry (DXA) at the baseline and after 12 months. RESULTS: Tibolone therapy produced significant increase of 4.1 and 1.8% in the BMD at the lumbar spine (p<0.001) and femoral neck (p=0.009), respectively. The combination of tibolone and active vitamin D increased the BMD by 8.0 and 4.4% (p<0.001) at the spine and femoral neck, respectively. The differences in the change of BMD from the baseline at the lumbar spine was significant (p=0.038) in the combination treatment group compared that in the tibolone alone group. CONCLUSION: Tibolone alone, and in combination with active vitamin D, effectively increased the BMD at all skeletal sites in postmenopausal women. Combination treatment for osteoporosis is emerging as a promising modality in Korean postmenopausal women.

Abstract PDF: The Fanconi's syndrome is characterized by generalized disturbance of proximal tubular function. It leads to excessive losses of amino acids, glucose, phosphate, bicarbonate, and other substrates handled by the proximal tubules. The metabolic consequences are acidosis, hypophosphatemia, hypocalcemia, osteomalacia, osteoporosis, and growth retardation. Adult Fanconi's syndrome is mostly secondary form caused by multiple myeloma, primary amyloidosis, light chain nephropathy, and heavy metal poisoning. We experienced 50-year-old woman with kappa light chain disease whose chief complaints were weakness of both lower extremities and multiple bone pain. This patient had renal glycosuria, hypercalciuria, normal anion gap type metabolic acidosis, osteomalacia and normal distal tubule acidification. Her bone marrow biopsy showed inappropriate proliferation of plasma cell. The patient underwent percutaneous renal biopsy in which was exceptionally observed focal effacement of podocyte foot process. So we report a case of osteomalacia caused by adult Fanconi's syndrome and foot process effacement by kappa -light chain disease.

Abstract PDF: Adrenal gland is a common site of metastatic tumors such as breast cancer, lung cancer, and colon cancer. When adrenal mass is found incidentally, adenoma is the most common among single adrenal masses. But in the case of bilateral adrenal masses, infection, bilateral metastases and hemorrhage are common. Secondary involvement of the adrenal gland is found in 25% of autopsy cases of non-Hodgkin's lymphoma. However, adrenal insufficiency is rare because it becomes apparent only when approximately 90% of adrenal cortex is destructed. We exprienced two cases of malignant lymphoma which involved the adrenal glands bilaterally. One case in which adrenal insufficiency was suspicious, was accompanied by hypovolemic shock and sepsis at the initial presentation. He died of sepsis combined with DIC even though hydrocortisone, intravenous saline infusion, and antibiotics therapy were started immediately. The other one was found incidentally, in which adrenal infiltraion was confirmed by CT scan. Hormonal level was normal and adrenal masses disappeared after chemotherapy.

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: BACKGROUND
Several clinical studies reported the efficacy of the long-acting SRIH analog, octreotide (Octreotide, Sandoz) in the treattnent of acromegaly. Recently, another SRIH analog (BIM 23014, Ipsen Biotech) was shown to decrease plasma GH levels in acromegalic patients. The recent availability of a long-acting formulation of BIM 23014 [slow release (SR) lanreotide] could avoid repeated sc injections or continuous sc infusions. The objective of this study was to determine the tolerability and effectiveness of the slow release (SR) somatostatin analog, SR lanreotide in active acromegaly. METHOD: Between March 1998 and May 1998, 10 patients were recruited in the prospective study carried out at Yonsei University. The effects of 6 weeks of SR lanreotide, given every 14 days at a dosage of 30 mg, im, were analyzed. All the patients completed the 6-week period of therapy. RESULTS: SR lanreotide injection produced 45% suppression of area under the curve of GH levels from the basal value on oral glucose tolerance test(OGTT). GH values on OGTT were normalized (< 2ng/mL) in 30% of patients after 6 weeks, whereas insulin-like growth factor I (IGF-I) levels were normalized in 50% of patients. No correlation was found between pretreatment GH levels and GH response to SR lanreotide or between changes in GH and IGF-I during therapy, The significant differences in response to SR lanreotide were shown between the patients with residual mass and no visible mass. During treatment, there was the significant reduction in the percentage of patients complaining of joint pain, hyperhydrosis, and paresthesias. Changes in soft tissue swelling were documented by a significant decrease in the diameter of fingers. Mild diarrhea and fatigue were the most frequent side-effects (20 30%) when SR lanreotide therapy was started. However, these side effects decreased progressively. Significant changes were noted in carbohydrate tolerance. CONCLUSIONS: These data indicate that SR lanreotide at a dose of 30 mg, im, every 14 days is an effective treatment in most unselected acromegalic patients, especially in patients with no visible mass. Tolerability to SR lanreotide therapy is high. The use of a new sustained release formulation of somatostatin analog is clearly advantageous in improving patient compliance with medical treatment for acromegaly.
