Polycystic Ovary Syndrome (PCOS) is currently believed a common endocrine-plurimetabolic disorder often associated to insulin resistance, diabetes mellitus, hypertension, hyperandrogenism, dyslipidemia and obesity, pathological conditions predisposing to high cardiovascular risk. Oxidative stress and endothelial dysfunction could represent early mechanisms of the cardiovascular risk in patients with PCOS. In order to confirm this hypothesis, 25 young (23.8±1.3 yr), over-w...

Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder in women of reproductive age often associated with insulin resistance, diabetes mellitus, hyperandrogenism, dislipidemia, obesity and hypertension, pathological conditions predisposing to high cardiovascular risk. Insulin resistant subjects may have higher plasma renin activity and it is well known that aldosterone plays a well-recognized role in the pathophysiology of hypertension and in the development of...

Paragangliomas (PGLs) and pheochromocytomas (PHEOs) are neural crest-derived tumors (NCD). PGLs can be localized in parasympathetic ganglia (in the head-neck region or in the anterior thorax) or in sympathetic ganglia (in the posterior thorax or in the abdomen). PHEOs can be considered PGLs arising in the adrenal gland.NCD tumors can present as sporadic or familial. The percentage of hereditary forms is supposed to be 25%. The susceptibility genes predis...
