Context: Osmotic stimulus or stress results in release of vasopressin. Animal studies have shown that inflammatory parameters such as interleukin-6 (IL-6) and interleukin-8 (IL-8) increase in parallel, mainly in central brain regions. Whether osmotic stimulation leads to an inflammatory response in humans is unknown. We therefore investigated the influence of osmotic stimulation on the inflammatory system in healthy volunteers.Method: In this prospective...

Introduction: Hyponatremia is the most prevalent electrolyte disturbance in hospitalized patients. Seasonal variation with higher incidence of profound hyponatremia during summer months has been described for patients in the emergency department setting. Whether this observation is also true among medical inpatients is unknown. This study aimed at analyzing the seasonal incidence of hyponatremia as well as sex and age specific differences among medical inpatients.<p class=...

Introduction: Knowing that only in 5–15% of FNABs the pathological analysis shows malignancy, enhance diagnostic accuracy is needed. The use of the TIRADS score and a revised version proposed by the British Thyroid Association (BTA) intend to determine if a FNAB should be performed or not in the evaluation of nodular goitre.Objective: To determine whether an adequate correlation is present between the risk category assigned to the nodules studied un...

Introduction: Giant prolactinomas are rare tumours, representing 2–3% of all prolactin (PRL)-secreting tumours. Their definition is restricted to pituitary adenomas with a diameter ≥4 or ≥2 cm of suprasellar extension, very high PRL concentrations (≥1000 ng/ml) and no concomitant GH or ACTH secretion. They are more common in young to middle-aged men. Endocrine symptoms are often present for a long period of time, but most times the diagnosis is made when...

Introduction: The developmental stages of the ovarian follicle are characterized by changes of gonadotropin and steroid hormone receptor expression and their potential interactions on the surface of granulosa cells. In this study in vitro, we aim to evaluate whether the co-existing follicle-stimulating hormone receptor (FSHR) and G protein-coupled estrogen receptor (GPER) form heteromers, which may play role in selecting the dominant ovarian follicle.<p class="abs...

Pituitary luteinizing hormone (LH) and placental human choriogonadotropin (hCG) are two heterodimeric glycoprotein hormones regulating reproduction. They bind the same receptor (LHCGR) expressed in gonadal cells, activating hormone-specific G protein- and β-arrestins-dependent signaling cascades, before LHCGR internalization. LH induces preferential proliferative signals, while hCG activates mainly the steroidogenic pathway, reflecting their physiological roles. In this s...

Introduction: The Quervain’s disease is an infrequent subacute thyroiditis (ST) that results in granulomatous infiltration of the gland’s parenchyma. Is usually diagnosed clinically based on cervical pain, systemic symptoms, altered thyroid function tests (TFTs) and history of upper respiratory tract infection. It is a benign self-limited condition that may share US features with malignancy which may result in improper therapy, including lobectomy.<p class="abs...

Background and objectives: Evaluate the impact of therapy with GLP-1 analogues (liraglutide) on glycemic control and weight in patients with type 2 diabetes and poor metabolic control.Material and methods: We conducted a retrospective observational study analyzing 67 patients with type 2 diabetes mellitus and BMI >30 kg/m2, over 6 months of treatment. We evaluated HbA1c and weight at 3 and 6 months, performing statistical analysis with SPS...

Introduction: The aim of this study was to evaluate effects on glycemic control, body weight and cardiovascular risk factors (BP, lipids and Epworth sleepiness scale) in diabetic patients with morbid obesity treated with exenatide.Material and methods: We studied consecutively 21 T2DM patients, all of them treated with metformin full dosage and insufficient metabolic control referred to our clinic for preoperative control of bariatric surgery. Twelve of ...

Patients with active Cushing’s syndrome (CS) have an increased coagulability and thrombotic tendency. High glucocorticoids concentrations increase plasma clotting factors, especially von Willebrand factor (vWf) and reduced fibrinolytic capacity. Thromboemobolic complications, mainly in the postsurgical phase, have been reported.Aim of this longitudinal study was to evaluate haemostatic and fibrinolytic markers in patients with active Cushing’s ...
