Objective: Many studies suggest that thyroid function modifies the process of healthy aging in humans. However, both a progressive increase and decrease of TSH with advancing age have been reported. The discrepancy may lie in the iodine intake in the population under, since low iodine intake results in an inverse association of TSH with age, while high iodine intake results in a positive association. We aimed to investigate whether FT4, FT3 and FT3</...

Introduction: Pituitary adenomas are benign neoplasms which grow slowly, but that can recur even after apparent radical resection. Until now, markers predicting regrowth and invasiveness have not been completely characterized.Design: We investigated cell proliferation and apoptosis parameters in 20 radically resected pituitary macroadenomas (six GH, two PRL, two ACTH, one FSH and nine non-secreting), in order to predict recurrence risk. Tumour regrowth w...

Introduction: Primary empty sella (PES) is a frequent ‘incidental’ finding reported in 5–25% of general population and is associated with endocrine abnormalities in 8–60% of cases. In this collaborative multicentric study we evaluated cardiovascular risk by assessing clinical characteristics, glucidic profile and lipid parameters.Design: A total of 94 PES patients (39M-55F; mean age 50.3±0.9 years; mean BMI 28.9±0.5 kg/m<sup...

Introduction: The highly active antiretroviral therapy (HAART) completely changed the natural history and body composition of the infected patients. The lipodystrophy syndrome of HIV-infected patients (IP) is characterized by fat mass redistribution in the limbs, face lipoatrophy and abdominal lipohypertrophy. Dual-energy x-ray absorptiometry scan (DEXA) and bioelectrical impedance (BIA) are techniques to determine body composition (BC).Aims: Evaluate th...
