Introduction: Ectopic Cushing’s syndrome (ECS) is due to ACTH secretion of no pituitary neuroendocrine tumors and represents around 5–10% of all cases of ACTH dependent Cushing’s syndromes.Methods: Six cases of ECS diagnosticated from 2008 to 2017 were studied. Patients’ age ranges from 36 to 69 years (mean 53), four females and two males. Three had pancreatic tumors, two small cell lung carcinomas and one pheocromocytoma. At diagnosi...

The Hippo pathway is involved in human tumorigenesis and regeneration. Here, we investigated the Hippo co-activator YAP1 and the kinase LATS1/2 in tumors of the parathyroid glands, which are almost invariably associated with primary hyperparathyroidism. Compared with normal parathyroid glands (n = 3), where YAP1 was detectable in the cytoplasm and in the nucleus, parathyroid adenomas (PAds; n = 10) had YAP1 accumulation mainly at the nuclear level, while in p...

BackgroundMost Differentiated Thyroid Cancer (DTC) cases typically show indolent biological behavior and a low mortality rate. Various prognostic systems are used to assess disease recurrence risk, to tailor treatment and follow-up strategies. The initial Risk Stratification System (RSS) and dynamic Response to Therapy Re-stratification (RTR) system, recommended by the 2015 American Thyroid Association (ATA) Guidelines, are the most employed. Still, they...

IntroductionThe term collision tumor refers to the coexistence of two histologically distinct malignant neoplasms. The two malignancies can originate from the same organ or occur as metastases from other regions. This type of tumors involving the thyroid gland are especially rare. Reported cases are usually involving papillary thyroid carcinomas in coexistence with other types of tumors like medullary carcinoma, follicular carcinoma or metastasic disease...

IntroductionMalignant insulinoma is a rare pancreatic neuroendocrine tumor that accounts for only 10% of all cases of insulinoma. The clinical picture is characterized by the presence of severe hyperinsulinemic hypoglycaemic syndrome in a patient with pancreatic tumor with locoregional and/or distant metastases. Therapeutic management is challenging due to the need to control both hypoglycemic syndrome and tumor growth. Curative surgery is rarely applica...

The gases nitric oxide (NO) and carbon monoxide (CO) function as intercellular messengers in a completely novel manner, providing a medium of cellular communication quite distinct from the classical neuroregulators. These agents will diffuse according to their physicochemical characteristics, in evanescent 'puffs' with spherical limits, unconstrained by formal cell boundaries. Most work has concentrated on their roles in inflammation and control of the vascular tree, but there...

Background: The management of adjuvant mitotane therapy in patients with adrenocortical carcinoma (ACC) is challenging. Plasma mitotane concentrations>14 mg/l have been associated with efficacy in the treatment of advanced ACC; however, data in the adjuvant setting are mixed. Moreover, there is no consensus on how to assess the optimal exposure to mitotane and all the proposed methods have inherent limitations. We have recently proposed a new method analogous to what is es...

Introduction: Identification of early responders is widely used in pharmacotherapy for weight loss to minimize unnecessary exposure to risks and unnecessary expenses. Gelesis Loss Of Weight (GLOW; NCT02307279), a multicenter, double-blind, placebo-controlled pivotal study, demonstrated that Gelesis100 offers a compelling new potential approach in the management of overweight and obesity.Objective: A post-hoc area under the curve (AUC) for the receiver op...

The aim of the present study was to evaluate the phenotype of PHPT, the adherence to International Guidelines and the rate of surgical cure of PHPT in Italy. From January 2014–January 2016, we conducted a prospective, multicenter (n=29 endocrine tertiary referral centers) study on patients with PHPT, recording clinical and biochemical data, parathyroid imaging and therapy choice at baseline and at last follow-up. The study group included 604 patients with PHPT, w...

Although differentiated thyroid cancer (DTC) has the third highest propensity to spread to the bone after breast and prostate cancer, there is a paucity of data concerning the treatment of bone metastasis (BM) in this setting. The MOSCATI (Metastasi OSsee da Carcinoma TIroideo) was a multicenter, retrospective study investigating the real-life outcome and management of BM in 143 patients (80 F, 63 M; median age 60 years) with DTC involving 10 specialized cente...
