Background: Active smoking has been associated with alterations of the hypothalamic-pituitary-adrenal axis. A role in the pathogenesis of adrenal tumors has also been proposed previously. No data investigating the relationship between smoking and hormonal secretion of adrenal tumors are yet available.Aim: To investigate the association between smoking habit with morphology and hormonal pattern of adrenal tumors.Methods: We retrospe...

Background: PCOS is characterised by increased production of ovarian and adrenal androgens. Obesity is closely connected to excess androgens and to the disruption of hormone circadian rhythmicity. To date, it is not clear whether hyperandrogenism in PCOS, complicated or not by obesity, is associated with androgen rhythm dysregulation.Aim: To investigate androgen diurnal rhythmicity and overall daily androgen exposure by measuring testosterone(T), androst...

Background: Adrenal incidentalomas (AI) are classified into mild autonomous cortisol-secreting (MACS) and non-secreting (NS) based on the 1mg-dexamethasone suppression test (DST). However, the latter test fails to detect alterations in the cortisol rhythm, which might be present in both MACS and NS.Aim: To characterize the cortisol secretion in terms of daily rhythm and exposure in healthy controls (HC) and patients with AI.Methods...

Background: Adrenal endothelial tumors are mainly represented by adrenal cavernous hemangiomas (ACHs) and adrenal cystic lymphangiomas (ACLs). They are rare incidental findings, with about 160 cases of both ACHs and ACLS reported in the literature. They are usually unilateral, benign, non-functioning, and asymptomatic, although abdominal pain and life-threatening retroperitoneal hemorrhage may occur if tumor size increases. Radiological features often overlap with malignant ad...

Background: Chronic hypercortisolism is known to alter the circadian rhythm and to impair protein metabolism. Altered amino acid (AA) and biogenic amine (BA) levels were found in basal blood in patients with hypercortisolism. However, poor information is available on the physiologic circadian fluctuation of these molecules. Furthermore, the potential derangement caused by hypercortisolism was never investigated.Aim: To characterize diurnal levels and flu...

Introduction: Differentiated thyroid cancers (DTCs) carrying BRAF and TERT mutations are associated with high-risk clinicopathological features and poor prognosis. However, there are currently no studies comparing BRAF-TERT tumors to other double mutated DTCs.Aim: To verify whether BRAF-TERT mutated DTCs differ from other double mutated DTCs in terms of clinicopathological characteristics and outcome.Materials and Methods: 168 DTCs...

Introduction: There is no clear indication for radioiodine treatment (RAI) in patients affected by differentiated thyroid cancer (DTC) in Stage I and ATA intermediate risk, according to American Thyroid Association (ATA) guidelines.Purpose: Our aim is to evaluate whether integration of BRAF status and thyroglobulin TSH-stimulated at the time of RAI (A-HTg) could further improve accuracy of stratification, and therefore therapeutic management, in DTC pati...

Background: Patients with hypoparathyroidism experience significant physical and cognitive symptoms and reduced health-related quality of life (HRQoL). Conventional therapy for hypoparathyroidism does not fully alleviate diminished HRQoL. The Hypoparathyroidism Patient Experience Scales (HPES) were developed to assess disease-specific physical and cognitive symptoms as well as the impact of hypoparathyroidsm on HRQol. TransCon PTH, an investigational long-acting prodrug of par...

Introduction: Although 18F-FDG-PET has found wide application in the management of radio-refractory differentiated thyroid cancers (RAI-R-DTCs), alternative radiotracers, including 68Ga-PSMA have been recently evaluated. Prostate-specific membrane antigen (PSMA) is in fact overexpressed in the microvasculature of several solid malignancies including thyroid cancers.Aim: To compare the diagnostic performance between 68Ga-P...

Background: HIV-infection is associated to several age-related comorbidities, such as a premature decline of serum testosterone (T). There is evidence about the relationship between health status, represented by frailty and comorbidities, and serum T levels in general population, while only one previous retrospective study investigated it in HIV-infected men.Aim: To investigate the association between frailty and gonadal status by assessing serum total T...
