Objectives: To date it is not clear to which extent a clinical, or even a subclinical, sexual dysfunction in the female partner might associate with erectile dysfunction (ED) in the male partner. The present study is aimed at the assessment of clinical features of ED associated with relational disturbances.Methods: In a consecutive series of 1140 male subjects reporting a stable couple relationship we evaluated the impact of relational factors, as assess...

BackgroundRadiofrequency ablation (RFA) seems to achieve a significantly larger nodule volume reduction rate (VRR) than laser ablation (LA) in benign non-functioning thyroid nodules (BNTNs). We compared the efficacy and safety of both thermal ablation treatments at the 12-month follow-up in patients with solid or predominantly solid BNTN.MethodsThis 12-month, single-use, randomized open-label parallel trial c...

ObjectiveWe report a case of acute respiratory syndrome coronavirus 2 (SARSCoV2) pneumonia in which persistently high procalcitonin (PCT) allowed the diagnosis of sporadic medullary thyroid cancer (MTC).MethodsWe describe the history of 43-year-old male with bilateral Sars-Cov-2 pneumoniae, in whom persistent increased PCT despite reduction of C reactive protein lead to investigate other causes of high PCT. S...

The von Hippel-Lindau (VHL) syndrome is an inherited multi-tumor disorder characterized by clinical heterogeneity and high penetrance. Pheochromocytoma (Pheo) is present in 10-15% of cases. It can be isolated or associated with other lesions such as hemangioblastomas, kidney cysts or cancer, and pancreatic lesions. Pheos secrete norepinephrine and are generally located in the adrenals. While performing genetic testing in patients affected by apparently sporadic pheos or PGLs, ...

Thyroid hormones (TH), among their pleiotropic actions, play a central role in the regulation of metabolism and in cognitive functions. Indeed, hypothyroidism is associated with a decrease in energy expenditure and lipid metabolism, and an impairment of memory. Metabolic deregulations induced by a high fat diet (HFD) generate peripheral inflammation, which promotes the development of neuroinflammation in various brain regions. This inflammatory state can disrupt neuronal homeo...

Background: Despite its desirable half-life and high-energy Auger electrons, 67Ga has been neglected as a therapeutic Auger electron emitter, due in part to lack of suitable chelators and targeting molecules.Objective: Here, 67Ga is compared with Auger electron emitter 111In as a therapeutic radionuclide in prostate cancer and breast cancer cell lines.Method: Plasmid pBR322 studies allowed direct co...

The CaSR, a G-protein-coupled receptor that regulates extracellular calcium (Ca2+o), predominantly signals via G-protein-αq/11 (Gαq/11), initiating IP3-mediated intracellular calcium (Ca2+i) accumulation, and mitogen-activated protein kinase (MAPK) signalling. CaSR also activates MAPK signalling via Gαi/o, or by associating with the scaffolding protein β-arrestin. CaSR g...

Background: Hypocaloric diets reduce the risk for type 2 diabetes (T2D) in obese subjects. However, there is a large inter-subject variability in the response to these interventions. The factors affecting this variability remain poorly understood. We and others reported that high plasma apoB-lipoproteins predict risk factors for, and incidence of, T2D in obese subjects independent of adiposity or fat distribution.Objective: To test the hypothesis that pl...

Introduction: High incidence of polyp formation and mucosal hypertrophy in paranasal sinuses have been reported in patients with acromegaly. Lund-Mackay score is widely used to stage chronic rhinosinusitis.Aim: To assess changes in Lund-Mackay score after surgical or medical treatment of acromegaly and their relation to biochemical disease activity.Methods: Records of patients with paired (before and after treatment) pituitary/sinu...

Autosomal dominant hypocalcaemia (ADH) is a disorder that needs to be distinguished from hypoparathyroidism, as ADH patients are at risk of nephrocalcinosis and renal failure when treated with activated vitamin D preparations. ADH types 1 and 2 are due to gain-of-function mutations of the calcium-sensing receptor (CaSR) and G-protein α 11 (Gα11), respectively. CaSR targeted drugs, known as calcilytics, rectify the gain-of-function associated with ADH1-causing mutatio...
