CONTEXT GH deficiency (GHD) in adults is associated with a cluster of cardiovascular risk factors that may contribute to an increased mortality for cardiovascular disease. OBJECTIVE The aim of this study was to evaluate the effect of GHD and GH replacement therapy on cardiac performance, lipid profile, and insulin resistance in children. DESIGN This was(More)
A total of 478 patients, mean age 15.5 (3.6-25.3) years, suffering from Turner's syndrome, were studied in order to determine the frequency of autoimmune thyroiditis, which is defined as the presence of antithyroid antibodies (AT-Ab) and typical ultrasound findings. We found 106 (22.2%) patients positive for AT-Ab and of those 49 (10%) also had positive(More)
Bone development is one of the key processes characterizing childhood and adolescence. Understanding this process is not only important for physicians treating pediatric bone disorders, but also for clinicians and researchers dealing with postmenopausal and senile osteoporosis. Bone densitometry has great potential to enhance our understanding of bone(More)
OBJECTIVE To study the natural history of Hashimoto's thyroiditis (HT) in children and identify factors predictive of thyroid dysfunction. STUDY DESIGN We evaluated 160 children (43 males and 117 females, mean age 9.10 +/- 3.6 years, with HT and normal (group 0; 105 patients) or slightly elevated (group 1; 55 patients) serum thyroid-stimulating hormone(More)
Primary ovarian insufficiency (POI) is a critical fertility defect characterized by an anticipated and silent impairment of the follicular reserve, but its pathogenesis is largely unexplained. The frequent maternal inheritance of POI together with a remarkable dependence of ovarian folliculogenesis upon mitochondrial biogenesis and bioenergetics suggested(More)
The bone mineral content (BMC) and the cortical thickness at the distal radius and at the II metacarpal were assessed in growing individuals (167 females and 158 males) by radiometric and quantitative roentgen microdensitometric methods. BMC adjusted for age and pubertal status was significantly higher in males than in females. However, the BMC corrected(More)
OBJECTIVE Mutations in the gene coding for the orphan nuclear receptor DAX1 cause X-linked adrenal hypoplasia congenita (AHC). Affected boys usually present with primary adrenal failure in early infancy or childhood. Impaired sexual development due to hypogonadotropic hypogonadism becomes manifest at the time of puberty. Moreover, evidence from Dax1(More)
CONTEXT Ig superfamily member 1 (IGSF1) deficiency was recently discovered as a novel X-linked cause of central hypothyroidism (CeH) and macro-orchidism. However, clinical and biochemical data regarding growth, puberty, and metabolic outcome, as well as features of female carriers, are scarce. OBJECTIVE Our objective was to investigate clinical and(More)
OBJECTIVE The differential diagnosis of male under-masculinization, including a wide spectrum of phenotypes and a heterogeneous genetic basis, is crucial for the correct management of the patients. To characterize an Italian population of under-masculinized males, we performed the molecular analysis of the SRD5A2 gene (2p23), encoding the 5alpha-reductase-2(More)
