Aim of the study was to evaluate whether clinical parameters and echographic patterns may be predictive of malignancy in thyroid nodules with a cytological diagnosis of follicular (FOL) and H?rthle cell (HC) neoplasia. The study included 495 patients (388 F: mean age 45±14 yr; 107 M: mean age 46±14 yr) with FOL (n=418) and CH (n=77) nodules, ‘cold’ at scintiscan and undergone to thyroidectomy. Clinical parameters considered were: sex, age, goi...

Introduction: Regulation of adiponectin in GH deficiency (GHD), which presents visceral obesity, is still a matter of debate. No studies have evaluated circulating adiponectin isoforms in adult GHD subjects. Aim of this study was to evaluate total adiponectin (TA) and its isoforms (high molecular weight: HMW, medium molecular weight: MMW, low molecular weight: LMW) in hypopituitary adult subjects with and without GHD, in relation to weight, IGF1 and GH levels.<p class="abs...

Introduction: The onset and progression of liver damage in non-alcoholic fatty liver disease (NAFLD) is tightly associated with metabolic derangements. Steroids may affect lipid metabolism but their alterations in the setting of NAFLD remain to be fully explored.Patients and Methods: We analyzed data from 267 patients with biopsy-proven NAFLD and 112 controls (CT). A panel of 26 steroids (including glucocorticoids, mineralocorticoids, androgens, and prog...

Introduction: Vitamin D plays an important role on musculoskeletal composition, but new evidences highlight others possible pleiotropic effects on many tissues and also metabolic functions. Vitamin D insufficiency should be associated with all-cause mortality, in particular with cardiovascular disease and metabolic syndrome. International studies suggested that 25(OH)D level sufficiency should be established at 30 ng/ml, insufficiency between 30 and 20 ng/ml and deficiency low...

In order to evaluate hypothalamic-pituitary-adrenal activity in diabetic patients in relation to neuroautonomic balance, we studied 50 consecutive hospitalized T2D patients (22F, 28M) without symptoms of neuropathy or hypercortisolism. We measured: morning, midnight and post-dexamethasone suppression cortisol (F8, F24 and F-Dex respectively) 24-hours urinary free cortisol (UFC), morning ACTH, systolic and diastolic blood pressure levels (SBP, DBP) and performed deep-breathing ...

Introduction: Acromegaly is a rare disease caused by chronic exposure to excessive levels of GH, usually related to the presence of a pituitary adenoma, and associated to somatic and visceral hypertrophy, metabolic alterations, respiratory and cardiovascular complications, and increased risk of neoplasias.Materials and methods: The prevalence of manifestations, complications and associated illness was evaluated in 137 acromegalic subjects (52 M, 85 F; ag...

ITT is the test of reference for the diagnosis of adult GH deficiency (GHD), but also GHRH in combination with arginine (ARG) or GH secretagogues (GHS) are considered equally reliable tests. Testing with GHS alone is, anyway, a potent stimulus exploring the integrity of hypothalamic pathways controlling somatotropic function.We therefore aimed to clarify the diagnostic reliability of testing with ghrelin, the natural GHS.We studied...

Aim of the study was to establish the diagnostic value of nuclear atypia thyroid nodules with cytological diagnosis of follicular (FOL) and Hv¨rthle cell (HC) neoplasia. 1039/23.313 fine needle aspiration (FNA) performed in January 2002 June 2005 in the Department of Endocrinology, University of Pisa had cytological diagnosis of FOL e CH. FNA was performed under echo guidance, using 23 gauge needle attached to 10 mL syringe. The material was air-dryed and stained with Pap...

The long-term risk of carcinogenic and genetic damage following the treatment with 131I for differentiated thyroid cancer (DTC) is quite low. The hypothyroid status (HS), at the time of 131I administration, decreases the renal clearance of 131I and increases the whole-body, blood and bone marrow irradiation, unlike the euthyroid status (ES). Chromosome aberrations (CA) in peripheral lymphocytes reflect blood cells exposure to irradiation. This ...

18-Oxocortisol (18-oxoF) is a derivative of cortisol (F) that is produced by aldosterone synthase (CYP11B2), and its clinical usefulness has not been clarified. We prospectively measured 18-oxoF, using highly sensitive liquid chromatography-tandem mass spectrometry (LC/MS/MS), in peripheral plasma of patients with primary aldosteronism (PA) who underwent adrenal venous sampling (AVS) to differentiate aldosterone producing adenoma (APA) from bilateral hyperplasia. The study was...
