Introduction: Insulinomas are rare pancreatic NETs presenting with chronic hypoglycaemia. Current guidelines for diagnosis require a prolonged fasting test (72 h), which implies hospitalization and is difficult to perform, delaying prompt diagnosis and treatment. It has been reported that 65 to 85% of insulinomas could be diagnosed after less of a 24h fasting period and 94 to 95.7% within 48h, although a shorter test for diagnosis has not yet been standardized.<p class="ab...

Introduction: Although the pathogenic mechanism is not completely understood, pharmacological treatments could negatively affect seminal parameters. The analysis of inflammatory (i.e. cytokines) and oxidative stress parameters represent a new tools to investigate the causes of idiopathic male infertility. The aim of this study was to evaluate the impact of medications on oxidative stress, inflammatory parameters and semen characteristics in male with idiopathic infertility.</p...

Introduction: Sporadic neuroendocrine neoplasms (NEN) occur rarely in young-adult (YA) patients, with an estimated incidence is about 2.8 cases per million, and data specific to their epidemiology are limited. The aim of our study was to better characterize the natural history, prognosis and management of NEN in YA patients (≤ 35 years old) compared to adult-elderly (AE; >35 years old).Methods: A retrospective observational study including 204 ...

Medullary thyroid carcinoma (MTC) is a rare type of tumor that originates from parafollicular C-cells and accounts for 3–4% of all malignant thyroid neoplasms. MTC presents as sporadic (75–80%) or inherited tumors (20–25%). Hereditary MTC is part of multiple endocrine neoplasia type 2 (MEN2). Aim of the study was to describe clinical presentation, prognosis and therapy of sporadic MTC patients. Sixty-seven patients (pts) with histologically confirmed MTC refe...

Neuroendocrine tumours (NETs) can be sporadic or can arise in complex hereditary endocrine disorders such as multiple endocrine neoplasias (MENs), familial paragangliomatosis (FPGLs), neurofibromatosis type 1 (NF1), von Hippel–Lindau disease (VHL), tuberous sclerosis (TSC). It has been estimated that hereditary NET occurrence varies with site of origin of the tumour, representing 5–30% of all cases of NET. These rates seems to be an underestimation and novel mutation...

Background and objective: 111In-DPTA-Octreotide (Octreoscan) has limited spatial resolution and a somewhat lower receptor affinity of the radiopeptide compared to DOTATATE, a novel somatostatin analogue, which can be radiolabelled with 68Ga and adapted for PET imaging, resulting in an increased spatial resolution. The aim of this study was to evaluate the diagnostic performance of 68Ga-DOTATATE PET in patients with NET and to compare this tecni...

Background and objective: Pituitary adenomas (PAs) affect about half of the patients with multiple endocrine neoplasia type 1 (MEN1); in the most of cases PA is a PRL-oma and generally more aggressive than the sporadic form. The aim of this study is to evaluate the recent changes in clinical presentation and therapeutic approach of MEN1-related PAs.Patients and methods: The study population included 17 patients with MEN1-related PA followed-up between 19...

Introduction and aim: Primary hyperparathyroidism (PHP) is the most frequent endocrine abnormality in MEN1 affecting about 100% of cases and inducing severe bone and kidney complications. Although surgery represents the only curative approach in MEN1 PHP, novel drugs are now available to effectively control PHP. The objective of this study was to show the recent changes in clinical presentation and therapeutic approach in MEN1-related PHP occurred in the last years.<p clas...

Context: Neuroendocrine tumors (NETs) are rare neoplasms, heterogeneous, with variable biological behaviour. NETs can be sporadic or they can arise in complex endocrine hereditary syndromes such as Multiple Endocrine Neoplasias (MEN), Familial Paragangliomatosis (FPGL), Neurofibromatosis type 1 (NF1), von Hippel-Lindau Disease (VHL), Tuberous Sclerosis (TSC) and Carney Complex (CC). By performing genetic screening, patients with hereditary NETs can be identified before the dev...

Background: Nodular goiter is one of the commonest endocrinopathy. Its incidence increases with age accounting for more than 50% of subjects older than 60 years. Elderly subjects more frequently suffer from pressure symptoms. Loco-regional treatments, like laser photocoagulation and percutaneous ethanol injection, are a potentially useful tool to treat TNs but their efficacy is still debated. Radiofrequency thermal ablation (RTA) has been applied to several benign and malignan...
