Introduction: In addition to its well known effects on calcium homeostasis and bone metabolism, growing evidences shows that vitamin D plays an important role in regulation of cancer angiogenesis, cell apoptosis, differentiation, and proliferation. Vitamin D acts through vitamin D receptor (VDR), an intracellular nuclear receptor. It was found an association between different cancer histotypes and single nucleotide polymorphisms (SNPs) of VDR. Despite the close relationship be...

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...
