Successful management requires accurate localization of the adenoma prior to surgery. Objective: To describe our institution’s experience in assessing the diagnostic value of parathyroid Fine Needle Aspirate (FNA) and PTH washout in localizing and confirming parathyroid adenoma. Methods: Twenty three patients (91.3% females) diagnosed to have primary hyperparathyroidism(PHPT) were enrolled in our study: parathyroid scanning (sestamibi), Ultrasound (US)and USguided FNA of the suspected parathyroid adenoma done to all patients by the same radiologist. The aspirate form FNA was washed out with one centimeter cubic normal saline and PTH was measured in the washout. Results: Mean(±SD) age was 51.3±13.5 year. Mean serum PTH ( 289.3±384.7) pg/ml and mean serum Calcium was (10.9±1.2) mg/ dl. Mean (±SD) PTH values in the washout is1172.3 ± 1877.6 pg/ml. Three patients had negative sestamibi scan but had positive results in PTH washout. The sensitivity and specificity of PTH washout are 82% and 100% respectively, with 100% positive predictive value and 67 % negative predictive value. For Sestamibi scan are 76.5% and 83.3% respectively with 92.9 % positive predictive value and 55.6 % negative predictive value and for ultrasound are 76 % and 67 % respectively with 87% positive predictive value and 50% negative predictive value. Conclusion: This study highlights the superiority of Parathyroid FNA with PTH washout over US or sestamibi scanning in confirming a parathyroid adenoma.

It is a matter of concern on global scale from a public health perspective and also in relation to rising societal costs. Once a disease of the West, type 2 diabetes has now spread to every country in the world from affluence to poor. The rising cost and ever increasing burden on health care resources to treat and monitor diabetes and its complications put a heavy financial and manpower burden on national health care systems. Asia’s large population and rapid economic development have made it an epicenter of the epidemic. Asian populations tend to develop diabetes at younger ages and lower BMI levels than Caucasians. Interactions between Westernized diet and lifestyle and genetic background may accelerate the growth of diabetes in the context of rapid nutrition transition. This epidemic is primarily driven by rapid urbanization, nutrition transition, and increasingly sedentary lifestyles. It reflects affluence and exposure to increased calorie intake in combination with sedentary lifestyle and less human energy expenditure. However, primary prevention through changes in public policies, the food and built environments, health systems and promotion of a healthy diet and lifestyle should be a global public policy priority.","PeriodicalId":73731,"journal":{"name":"Journal of endocrinology and diabetes","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49280738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study was aimed to classify type 2 diabetic patients phenotypically based on the obesity indices and to study the prevalence of each phenotype. Methodology: This study included 336 type 2 diabetic patients who attended Kasturba Medical College Hospital, Mangalore. Their waist circumference and body mass index were measured. Based on these measurements they were classified into four phenotypes as follows: Generalized obesity: high values of waist circumference and body mass index. Truncal obesity: high values of waist circumference and normal body mass index. Non-obesity: Normal values of waist circumference and body mass index. The details of glycaemic index, anti-diabetic drug usage, and diabetic complications exhibited were collected from case records. Results: 71% (n=238) of type 2 diabetic patients had generalized obesity, 16% (n=54) of type 2 diabetic patients had truncal obesity, and 13% (n=44) of type 2 diabetic patients were non-obese/lean. There was no significant difference in the HbA1c level between obese and non-obese diabetics.

Materials And Methods: Cross sectional study was done on 250 patients with type-2 diabetes mellitus subjects attending medicine clinic , King george’s medical university (KGMU) lucknow, india. Subjects were screened for diabetic nephropathy depending on the base line parameter, clinical history of disease and documented in pretested proforma. Routine blood parameters, HbA1C and 24 hrs urine microalbumin level were carried out in department of pathology. Result: The level of HbA1c was higher among the patients of nephropathy (8.54±0.97) compared with non-nephropathy (7.32±0.84, 95%CI=7.17-7.47). Increased HbA1c was found among both 5-10 and >10 years diabetic duration . However, HbA1c was similar among all duration of diabetes groups within non-nephropathy. The total cholesterol (TC), HDL cholesterol (HDL-c), LDL cholesterol (LDL-c) and VLDL cholesterol (VLDL-C) were almost similar in HbA1c range <7, 7-8.9 and 9-10.9 and without insignificant differences (p>0.05). Although, Triglyceride (TG) level was significantly higher in HbA1c 9-10.9 (174.20±48.95mg%) than 7-8.9 (159.66±31.47mg%) and <7 (158.82±29.67mg%) . High prevalence of nephropathy was found among HbA1c range 9-10.9 (Urine albumin :246.35±126.29mg/d) compared with 7-8.99 (Urine albumin :159.89±70.16mg/d) and <7 (Urine albumin :132.80±90.33mg/d) respectively. Conclusion : HbA1c cut-off >7 % should be considered as an index of glycemic control as well as important tool for over all metabolic derangement and target organ damage among diabetes population. Hence, establishment of HbA1c cut-off value with long duration of diabetes might be useful for prediction of treatment control and prevention of renal failure.

Our aim was to investigate the levels of lipocalin-2 (LCN-2) and soluble Lectin-like oxidized low-density lipoprotein receptor-1(sLOX-1) levels in both diabetics and prediabetic with comparison to non-diabetic subjects. We also examined the association of LCN-2 with sLOX-1 and albuminuria Methods: One hundred forty-two subjects with type 2 diabetes mellitus, 32 prediabetic subjects, 58 non-diabetic controls were consecutively enrolled in this study. LCN-2 and sLOX-1 levels were measured with ELISA assays. Results: LCN-2 levels didn’t show significant difference between diabetics, prediabetic and control groups (p = 0.864). sLOX-1 levels were significantly lower in diabetic group (2.53 ng/mL, median) compared with prediabetic (2.84 ng/mL, median; p = 0.041) and control groups (3.00 ng/mL, median; p = 0.001). Multiple linear regression analysis showed that urinary albumin excretion and sLOX1 were independently associated with LCN-2. When logistic regression analysis was performed LCN-2 was independent factor determining albuminuria (p = 0.021; OR, 1.001; (1.000-1.001) 95% CI). Conclusion: Our study provides the first clinical evidence demonstrating serum LCN-2 concentrations are independently associated with sLOX-1 levels which were found to be lower in type 2 diabetics unexpectedly.

Our focus on pre-weaned porcine islets (4-11 days old; PPIs) has shown that this model of porcine islets is a cost effective and viable mean to isolate and culture islets for transplantation. Exendin-4 (Ex4) could improve islet viability, islet expansion, and insulin secretion. PPIs are immature after islet isolation and the addition of growth factors could accelerate their maturation. This study investigated the effects of exposure to Ex-4 on the maturation of freshly isolated PPIs during in vitro culture. Methods: Pancreata from pre-weaned piglets (4-11 days old) were partially digested using low-dose collagenase and culture at 37°C and 5% CO2 for up to 3 days. 10nM of Ex-4 was added to culture media of freshly isolated PPIs. After 3-day culture, islets were assessed for islet yield, size, purity, membrane integrity, cellular viability and composition, and in vitro function. Results: Islet count (IC) was significantly higher in the Ex-4 group than in the control group. Islets treated with Ex-4 were significantly smaller than islets from the control group. The percentages of major endocrine cells (β-cells, α-cells, and δ-cells) were similar in both groups. Ex-4 supplementation significantly increased insulin secretion in response to glucose challenge. Conclusions: The addition of Ex-4 to culture media of freshly isolated PPIs could improve islet counts and produce islets with enhanced glucose-stimulated function. Culturing PPIs in Ex-4 could be beneficial to improve islet quality before transplantation.","PeriodicalId":73731,"journal":{"name":"Journal of endocrinology and diabetes","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67332623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
