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...

Context: Until now the role of medical therapy in patients with primary hyperparathyroidism (PHP) was mainly based on the use of bisphosphonates. Recently, cinacalcet hydrochloride was reported to be effective in control hypercalcemia in PHP. The aim of this study was to evaluate the efficacy of cinacalcet in PHP patients who were not effectively controlled with alendronate.Patients and methods: Fourteen PHP patients (mean age 64.1±2.6) were include...

Background: Expression of somatostatin receptor (SST) and therapy with somatostatin analogues have been scarcely investigated in parathyroid tumors.Objective: To evaluate the effects of depot long acting octreotide (OCT-LAR) on primary hyperparathyroidism in patients affected with multiple endocrine neoplasia type 1 (MEN-1).Subjects and methods: Eight patients with a genetically confirmed MEN-1 were enrolled. All patients presented...
