Introduction: Gastrinoma is rare gastrin-secreting neuroendocrine tumor (NET), usually located in the pancreas or duodenum. The most common presentations of gastrin secreting tumor is Zollinger-Ellison Syndrome (ZES). Only about 10% of patients have non demonstrable ulcer.Case presentation: A 67 years old female, with premature menopause, mild hypothyroidism with optimal replacement treatment, osteopenia and history of chronic gastritis, is admitted to o...

Background: To characterize the diagnostic performance of 18-Fluoroethylcholine-PET-CT (FCH-PET-CT) to localize parathyroid adenomas (PA) in primary hyperparathyroidism (pHPT) when ultrasound (US) and MIBI-Scan (MibiS) fail to localize – intraoperative correlation and one-year follow up.Method: Beginning in 07/2017 18-FCH-PET was employed in patients with proven pHPT in whom US and MS delivered either incongruent or negative findings. All patients ...

Aim: To test the hypothesis that exposure to insulin glargine might be associated with increased risk of cancer mortality compared with human basal insulin preparations.Materials and methods: All consecutive diabetes patients aged over 40 years, residing in a major urban area were screened at their first diabetes outpatient visit between 01/01/2001 and 12/31/2008 (n=79 869). Exclusion criteria were insulin treatment at screening (n=14 7...

Background: Latent autoimmune diabetes in adults (LADA) is a form of autoimmune diabetes with a slower decline of β cell function and distinct features from type 1 and type 2 diabetes. LADA is also a very heterogenic group. Frequently LADA is associated with other autoimmune diseases especially endocrine diseases.Aim: To evaluate prevalence of thyroid autoimmunity (TA) and its impact on cardiovascular risk and metabolic syndrome in LADA patients.</p...

Introduction: Cryptorchidism is unilateral or bilateral absence of the testes from the scrotum. One of the differential diagnosis is congenital bilateral anorchia. Vanishing testes syndrome is associated with low serum AMH concentrations and an absent or subnormal response to stimulation with hCG. We report the case of a 22-year-old boy diagnosted with bilateral cryptorchidism and hypergonadotropic hypogonadism at the age of 17 years old. At the time of diagnosis the scrotum w...

Introduction: Primary hyperparathyroidism is typically caused by a parathyroid adenoma (80-85% of the cases). Very rare causes are represented by parathyroid carcinoma and atypical parathyroid adenoma (0.5-1.5% of the cases). Atypical parathyroid adenomas have atypical histological features, not sufficient to be considered a carcinoma, and have an uncertain malignant potential and risk of recurrence. We report the case of a 66-year-old man referred from another medical center ...

Introduction: Hybrid closed loop (HCL) systems are made up of continuous glucose monitoring (CGM) sensor, an algorithm that receives the readings from the CGM and an insulin pump able to deliver variable insulin doses according to the information received from the other two parts. Predictive low-glucose suspend (PLGS) insulin pump is able to stop the administration of insulin before hypoglycemia occurs. These new technologies are meant to improve the quality of life and help t...

Obesity was considered to be a protective condition against osteoporosis. New studies suggest that visceral obesity is associated with low BMD and a higher risk for fracture. Patients with diabetes mellitus, although they do not have a lower BMD, have a higher fracture risk, probably due to the lower bone turn over.Aim: The aim of the study was to evaluate bone metabolism in connection with hormonal profile in postmenopausal women with metabolic syndrome...

Menopause is a physiological condition associated with an important change in the hormonal status, an adverse lipid profile and cardiovascular risk. Apolipoproteins are proteins that bind to lipids to transport them. Apolipoprotein intestine synthesis is regulated principally by the fat content of the diet, while in the liver by dietary composition, hormones, alcohol intake and lipid lowering drugs. Are they changed due to aging? Do they interfere in the hormonal changes?<...

Simultaneous knockout of the neuroendocrine marker genes Ptprn and Ptprn2, which encode the protein tyrosine phosphatase receptors N and N2, respectively, causes infertility of female mice while males are fertile. To clarify the mechanism of sex-specific roles of Ptprn and Ptprn2 in mice reproduction, we analyzed the effects of their double knockout (DKO) on the hypothalamic-pituitary-gonadal axis. In DKO females, a delay in puberty and lack...
