In this observational, retrospective, multicenter study, we analyzed data from 300 patients with pituitary incidentaloma followed in two Italian Hospital Center. We observed a predominance of female patients (65%), with an a mean age at diagnosis of 49 years (higher in men than women, 57 vs 45 years old). The main reason to perform imaging were neurological symptoms not related to the presence of adenomas (56%). Most cases were microadenomas (56%), and macroadenomas were more ...

The recent discovery of the presence of brown adipose tissue (BAT) also in human adults is pivotal for development of anti-obesity therapies. This type of fat, in fact, mainly consists of brite cells (brown adipocytes appearing for a browning process in white fat) which are involved in adiposity control. The origin of brite cells in adult white adipose tissue (WAT) is still unclear as human cell models are lacking.Our study demonstrated the presence of B...

Pituitary antibodies have been measured mainly to identify patients whose disease is caused or sustained by pituitary-specific autoimmunity. Although reported in over 100 publications, this antibody test has variable results and limited clinical utility. Our goals were to: identify major sources of variability; test them experimentally for establishing an optimized immunofluorescence protocol; assess prevalence and significance of pituitary antibodies in patients with pituitar...

Introduction: Some variants of the glucocorticoid receptor (GR) gene have been found to alter glucocorticoid sensitivity and have been associated with worsen metabolic profiles.Objective: The aims of the present study were: i) to examine whether the prevalence of N363S, ER22/23EK and BclI variants was different in patients with adrenal incidentaloma (AI) and/or subclinical Cushing’s syndrome (SCS) than control subjects and ii) whether the presence o...

Introduction: Bone marrow fat is considered a risk factor for osteoporosis and fragility fracture. It is not clear if bone marrow adiposity is increased in obesity and how it relates to other compartments of adipose tissue, in particular visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), and epicardial adipose tissue (EAT).Aim: To evaluate bone marrow adiposity in obese as compared with normal weight women.Design: Tw...

Introduction and objective: Prophylactic central lymph node dissection (CLND) in patients with suspected papillary thyroid cancer (PTC) without evident lymph node metastasis (LNM), remains debatable. We propose to evaluate whether BRAF V600E mutation presence, could help to identify patients at risk for LMN.Methods: Retrospective study of patients with diagnosis of PTC, who underwent total thyroidectomy during 2002 and 2013 (n: 256) in our hospi...

Background: Primary hyperparathyroidism (PHPT) is characterized by an excessive secretion of the parathyroid hormone (PTH) with normal or high calcium levels. The gold standard therapy involves minimally invasive parathyroidectomy with intraoperative PTH (ioPTH) monitoring. Different criteria have been identified when predicting cure rates using ioPTH values.Objective: To evaluate the percent ioPTH drop (ΔioPTH), the post-excision ioPTH, the first p...

Background: Persistent vaginal bleeding can be psychologically stressful and incongruent with gender identity in transgender men (assigned female at birth with male gender identity). Previous studieshave cross-sectionally described amenorrhea in cohorts of transgender men on intramuscular or subcutaneous testosterone injections. It remains uncertain which testosterone preparations most effectively suppress vaginal bleeding and when amenorrhea occurs after testosterone initiati...

Obesity is the single most significant risk factor for testosterone deficiency in men, with a reported prevalence up of 60% of male obesity secondary hypogonadism (MOSH). Several studies have shown that significant weight loss due to bariatric surgery have significant metabolic and endocrine improvement in obesity, however the results achieved with conventional diet and lifestyle change are poor and not able to reverse this condition. As an alternative to bariatric surgery, we...

Anabolic therapies represent a major advance in the management of severe osteoporosis. Parathyroid hormone (PTH) and human recombinant PTH peptide 1–34 (Teriparatide) demonstrated an increase in bone mineral density and a significant reduction in vertebral fractures in patients with osteoporosis when given for 18–24 months. The intermittent administration of PTH or teriparatide stimulates osteoblastic function, improves bone architecture and has an additional analges...
