Introduction: The approach for initial thyroid hormone suppression in patients who undergo surgery for differentiated thyroid cancer (DTC), is based upon the risk of disease recurrence. In particular, recent American Thyroid Association guidelines suggest to maintain TSH levels between 0.1 and 0.5 mU/l and less than 0.1 mU/l for patients with ‘intermediate’ and ‘high’ risk respectively. The aim of the study is to identify the major predictive factors of LT4...

Introduction: Primary aldosteronism (PA) features a higher prevalence of cardiovascular events and renal complications as compared with essential hypertension. The effects of aldosterone excess on ascending aorta have never been investigated in human subjects.Methods: From August 2014 to December 2015, we enrolled forty-seven consecutive PA outpatients who had not undergone surgery of the adrenal mass. Hypercortisolism and pheochromocytoma were excluded....

Introduction: It is known that thyroid disorders can influence menstrual cycle, but subclinical hypothyroidism (SH), as cause of ovulation disorders and luteal deficiency (LD) in particular,is underestimated. Monitoring women’s cycles, according to the Billings Ovulation Method (BOM), can allow a precise timing for hormonal evaluation and diagnose LD. Usually, a basal TSH value of 2.5 mg/ml is considered as cut-off for a good luteal function, but alone cannot identify all...

Introduction: Physical exercise exerts several effects on endocrinological homeostasis and, in particular, sprint exercise elicits the largest testosterone response per unit of work, while in response to prolonged endurance exercise testosterone levels will typically decline. In contrast to a large amount of paper about the modification of testosterone during physical exercise few study evaluated how DHT was influenced by a single bout of aerobic exercise.<p class="abstext...

Introduction: Decreased bone mineral density (BMD) in Klinefelter syndrome (KS) is frequent and it has been traditionally related to low testosterone levels. However, low BMD can be observed also in patients with normal testosterone levels and testosterone replacement therapy does not necessarily increase bone mass in these patients. Nothing is known about vitamin D levels and supplementation in KS. In this study we determine vitamin D status and bone mass in KS subjects and c...

Kisspeptin is a neuropeptide secreted in anteroventral-periventricular and arcuate hypothalamic nuclei involved pubertal onset and in other functions of adult life. Kisspeptin levels are sex dependent, so they are higher in prepubertal girls and in adult women compared to age-matched male. This sex-related pattern has been reported in adult obesity, but few data are reported in childhood obesity. In order to evaluate correlations between metabolic status and kisspeptin, we stu...

It is known that in type 1 diabetes mellitus (T1DM) continuous subcutaneous insulin infusion (CSII) therapy improves metabolic control and reduces risk of hypoglycaemia in comparison with multiple daily injection (MDI). Metabolic outcomes usually considered are HbA1c, BMI, and inflammatory parameters. However few data are available on pituitary and gonadal hormone responses, which are involved in metabolic processes. In order to study the response of anabolic hormones in patie...

The full-length retinoblastoma interacting zinc-finger protein (RIZ), codified by ten exons, has tumour suppressive and differentiating properties and is known to be a downstream effector in classical oestrogen target tissue. In many normal and malignant tissues alternative splicing isoforms, RIZ1 and RIZ2, frame-shift mutations and/or exon deletions have been found, but their oncogenic role is still debated. Although the presence of RIZ1 in the testis has been described, in g...

Introduction: Amyloidosis due to Apo A-I Leu75Pro mutation is a rare form of hereditary amyloidosis with systemic involvement mainly of testicle, kidney and liver. This disease finds a wide prevalence in the province of Brescia (Northern Italy), which represents a geographic uniqueness for the spread of this amyloidosis form. Somefeatures of this disease have not yet been described.Purpose: To describe the frequency of organ damages in this amyloidosis f...

Background: Pasireotide is a multi-ligand somatostatin analogue licensed in a long-acting release formulation (PAS-LAR) for the treatment of acromegaly. The real-life reports with PAS-LAR are still scanty.Objectives: To assess the efficacy and safety of PAS-LAR in patients with acromegaly.Patients and methods: Prospective observational multi-centre study enrolling acromegalics evaluated before (baseline) and 1, 6, 12, 24, and 36 mo...
