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...

It has been demonstrated that hypothryoidism could affect the prognosis of patients with cardiovascular disease. The aim of this study was to better clarify the prognostic role of hypothyroidism in patients with chronic heart failure (CHF).We enrolled 384 consecutive outpatients (65±13 years, 296 males, NYHA 2.3±0.6, left ventricular ejection fraction, LVEF, 32±9%) with CHF (ESC criteria), in stable clinical conditions (at least 30 days) a...

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...

Multiple endocrine neoplasia type 2 (MEN 2) is characterized by the presence of medullary thyroid cancer (MTC) and other benign pathologies. RET mutations are responsible of this disease and their screening is a very sensitive tool for the identification of gene carriers (GC).Aim of this study was to verify the relevance of the basal and pentagastrin (Pg) stimulated serum calcitonin (CT) in the decision to perform TT in GC. We reviewed data of 65 GC foun...

Papillary thyroid microcarcinoma (mPTC) is being diagnosed increasingly frequently. Multifocality and nodal involvement are sometimes reported on diagnosis. Management ranges from observation to total thyroidectomy (Tx) followed by radioiodine (RAI) ablation. The role of rhTSH testing in mPTC has not been fully investigated. Torlontano et al. (2006) recently observed that rhTSH-stimulated Tg levels mainly depend on normal tissue remnant. Aim of this study was to further...

Obesity has long been recognized as an independent risk factor in heart failure. The mechanisms proposed to explain this correlation include hemodynamic changes secondary to obesity, leading to left ventricular remodeling and systolic dysfunction, and cardiomyocyte apoptosis induced by increased lipid accumulation into cardiomyocytes. Adipose tissue is an endocrine organ that secretes a wide variety of bioactive factors, which seem to mediate communication between adipose tiss...

Serum CT is the most specific marker of Medullary Thyroid carcinoma (MTC). Although Pg test is the most frequently used to induce CT secretion, the poor availability of Pg makes it necessary to look for different agents. Aim of this work was to compare the induction of CT secretion following 2 different stimuli in the same patient. We studied 25 patients (14 females, 11 males; mean age 50±15 yrs; range 12–77 yrs). All patients were subjected to both tests by injectio...
