Introduction: Diagnostic and post-therapy radioiodine whole body scan (WBS) is used in the follow-up of differentiated thyroid carcinoma (DTC) for the detection of local recurrence or remote metastasis. We report a case of false-positive uptake of radioiodine WBS.Case report: A 37-year-old female patient underwent subtotal thyroidectomy for multinodular goitre and histology revealed multifocal papillary thyroid carcinoma, of follicular type with three fo...

A 27-year-old male patient during past 10 years noted a gradual change in his appearance, but began to seek a medical attention only 1.5 years ago due to reduced vision. Hormonal tests from March 2013 revealed marked elevation of GH to 106 mIU/ln (ref. values <20), and IGF1 to 567 ng/ml (121–336), decrease in testosterone levels to 1.91 ng/ml (3–12), with cortisol, LH, FSH, PRL, TSH values within the reference range; MRI of the brain showed a 4×7 mm adenoma ...

Background: Phosphatidylinositol-3-kinase (PI3K) is a critical mediator of insulin action, and influences cellular growth, survival and metabolism. Recently, somatic gain-of-function mutations in the p110α catalytic subunit of PI3K (PIK3CA) have been found in a spectrum of overgrowth disorders, outlining the possibility of treatment with inhibitors of the PI3K–AKT–mTOR pathway.Methods/Results: A 37-year-old female, presented with life-long...

Congenital hyperinsulinaemic hypoglycaemia is generally characterised by low levels of ketone bodies, fatty acids and branched chain amino acids at the time of severe hypoglycaemia, and by a requirement for a relatively high rate of glucose infusion (>10 mg/kg per min) to maintain euglycaemia. It is caused by physiologically inappropriate insulin secretion from the pancreatic beta cells due to mutations that uncouple insulin secretion from normal hyperglycaemic and other s...

Background: Pituitary adenomas are monoclonal neoplasms that may be either functional (hormone-secreting) or non-functional. The processes associated with pituitary tumor development and progression are mostly unknown. Remodeling of the extracellular matrix (ECM) and cell adhesion were suggested to be involved in pituitary tumorigenesis. Heparanase, an endoglycosidase capable of degrading heparan sulfate, the main polysaccharide constituent of the ECM, is implicated in diverse...

Male transgenic (TG) mice overexpressing both the hCGα- and hCGβ- subunits present elevated levels of circulating hCG, Leydig cell hyperplasia/hypertrophy, elevated androgen levels and infertility (Rulli et al. 2003). In addition, serum FSH is significantly reduced in prepuberal and adult TG males compared with wild-types (WT), and does not change after treatment with the antiandrogen flutamide. The aim of this study was to evaluate the regulation of the hypot...

Aims: We investigate the influence of GIP on ghrelin secretion in normal glucose tolerant individuals with the use of the firstly applied correlation network analysis on human plasma metabolome data.Methods: To address this issue, we employed a GIP-infusion test and euglycemic- and hyperglycemic glucose clamp experiments combined with infusion of GIP or placebo in a cross-over manner in non diabetic obese male subjects (n=14). Moreover, we firstly...

Introduction: In patients with primary hyperaldosteronism, distinguishing between unilateral and bilateral adrenal hypersecretion is critical in assessing treatment options. Adrenal venous sampling (AVS) has been advocated by some to be the gold standard for localization of the responsible lesion however is invasive, technically challenging, and difficult to interpret. Adrenal computed tomographic scanning (TC) is mandatory before AVS but more studies are warranted to identify...

BackgroundEpidemiological studies revealed up to 5-6 undiagnosed cases of type 2 diabetes mellitus (DM2) per 1 registered patient. The late diagnosis of DM2 presents a medical and socio-economic problem.The aim of the study to identify the most cost-effective, easy-to-use method for regular screening for DM2 in primary care settings in the Republic of Uzbekistan.Materials and methods4 d...

Background: Metformin is one of the first line drugs used to treat type 2 diabetes mellitus, even though there are still many gaps on how exactly metformin works. This is due to many years of research using various concentrations of metformin and also, not considering the conditional effect that glucose can have in its action.Objectives: Study the effect of different concentrations of metformin and glucose in cell culture.Methods: ...
