Background: In patients with Klinefelter syndrome (KS) morbidity and mortality seem to be higher than general population, this depending on a wide number of possible comorbidities. Impaired metabolic profile, increased risk of venous thrombosis and the consequent increase of cardiovascular diseases might play a key role in this condition as well as reduced bone mineral density and higher fracture risk. Nowadays testosterone replacement therapy (TRT) is the first-choice treatme...

Introduction: Accurately discern malignant from benign nodules sometimes represents a real challenge. Fine needle aspiration (FNA) biopsy, ultrasound and The Bethesda System for Reporting Thyroid Cytopathology (BSRTC) allow for accurate diagnosis in 60–80% of all nodules. However, 10–20% of thyroid FNAs yield an indeterminate cytology (BSRTC III and IV categories). The real malignancy rate of BSRTC III category is difficult to ascertain because histopathological anal...

Background: Vitamin D has several ‘noncalcemic’ implications, including effects on cell signaling and differentiation. Patients with gastroenteropancreatic (GEP) neuroendocrine tumors (NET) have an increased risk of vitamin D deficiency, due to the tumor itself, systemic therapies and abdominal surgery. However, data regarding vitamin D status are limited. Aim of this study was to evaluate 25-hydroxy-vitamin-D (25(OH)D) levels in GEP-NET patients and correlated them ...

Objective: To evaluate the real-world experience of patients with generalized (GL) and partial (PL) lipodystrophy initiating treatment with metreleptin as part of an early access program (EAP).Methods: A retrospective data collection was conducted from four countries for patients enrolled in the EAP. A descriptive analysis was performed on selected patient characteristics, baseline organ impairments and complications, and response to metreleptin therapy,...

Background: human immunodeficiency virus (HIV)-infection is strongly associated to erectile dysfunction (ED) in men. Preliminary data suggests that ED is poorly associated with serum T in HIV+ men.Aim: To investigate in HIV-infected men the relationship between sexual function as assessed by the validated International Index of Erectile Function (IIEF-15) and T deficiency using Liquid Chromatography-tandem Mass Spectrometry (LC-MS/MS).<p class="abste...

: Non-thyroidal-illness syndrome (NTIS) is present in chronic renal failure and considered an adaptive mechanism. However oxidative stress is linked to NTIS in a vicious circle, due to deiodinases alteration and negative effect on antioxidant levels or activity. One key antioxidant, protective toward ROS-mediated tissue damage, is extracellular superoxide-dismutase (ec-SOD), present in extracellular matrix and with a role in mediating nitric oxide-induced signaling. ec-SOD is ...

Background: Stimulated Thyroglobulin levels measured at the time of remnant ablation (Htg-A) and BRAFV600E mutation were shown to have prognostic value in predicting persistent disease in DTC. The aim of this study was to evaluate the prognostic role of Htg-A combined with BRAFV600E status in association with revised American Thyroid Association (ATA) risk stratification.Patients and methods: 620 patients treated for a DTC were included in this study wit...

Introduction: Due to the absence of randomized controlled trials, management of low risk papillary thyroid cancer (PTC), which represents the most commonly diagnosed form of thyroid malignancy, remains controversial. Hashimoto’s thyroiditis (HT) is significantly more frequent in patients with PTC, as compared with subjects carrying benign lesions as well as different tumour histotypes. Despite still controversial, HT is considered a protective factor in PTC being associat...

Introduction: Cells with stem-like properties have been reported in benign and malignant thyroid diseases, and can be propagated by culturing them as non-adherent spheres.Design: Aim of the present study was to widely characterize the stem-like cells in tumor and normal thyroid tissues and in the corresponding in vitro-cultured thyrospheres, and to investigate in vivo the proangiogenic potential of thyrospheres in a zebrafish model....

It is known that high levels of TSH are associated with higher miscarriage risk, though the precise TSH cut-offs are debated. Aim of the present study was to evaluate if pre-conceptional TSH levels associate with increased risk of early miscarriage in a large series of infertile women submitted to IVF and to determine the threshold of TSH associated with the highest prevalence of pregnancy loss. We retrospectively studied 1484 infertile women (mean±age 36.7±4.1 years...
