Randomized Controlled Trial Multicenter Study Clinical Trial
Final height data, body composition and glucose metabolism in growth hormone-treated short children born small for gestational age.
Low birth weight has been associated with impaired insulin sensitivity, type 2 diabetes mellitus, hypertension and cardiovascular disease in later life. GH therapy is known to increase fasting and postprandial insulin levels. For this reason concern has been expressed regarding the possible detrimental effects of GH therapy in children born small for gestational age (SGA). ⋯ However, as has been reported in other patient groups, GH induced higher fasting and glucose-stimulated insulin levels, indicating insulin resistance. After discontinuation of GH serum insulin levels returned to normal age-reference levels. Short SGA children have a reduction in bone mineral content and lean body mass when compared with healthy controls, which significantly improved (normalized) with GH therapy at a dose of 1 mg/m(2) per day.

Multicenter Study
Adrenal incidentaloma: an overview of hormonal data from the National Italian Study Group.
Adrenal masses are more and more frequently detected by adrenal ultrasound, computed tomography or nuclear magnetic resonance carried out for a reason other than the suspicion of adrenal disease (incidentalomas). The findings of an incidentaloma still leaves many diagnostic and therapeutic questions open. We report the results of a multicentric retrospective evaluation of patients with adrenal incidentalomas, performed by a Study Group of the Italian Society of Endocrinology. ⋯ Post-ACTH 17-OH progesterone levels were elevated in 52% (62/118 patients) of non-functioning adenomas and in 2 of 4 carcinomas. Not enough data are yet available postoperatively. In summary, endocrine evaluation can lead to the identification of a nonnegligible number of cases of clinically unsuspected pheochromocytomas and subtle hypercortisolism (about 3.4 and 6.2%, respectively of all adrenal incidentalomas), while cases of primary subclinical aldosteronism are rarely found.
