Background: There is a great controversy on whether subclinical hypothyroidism (SH) in children should be treated for TSH values between 4.5 and 10 mU/l. In adults SH has been associated with abnormalities in lipid profile and increased risk of atherosclerosis. Data in untreated SH children are scanty.Objective: The aim of this cross-sectional controlled study was to evaluate in children the effects of long term untreated SH on lipid profile and endothel...

Background: Adults with untreated GH deficiency (GHD) may have a cluster of cardiovascular risk factors. The effects of GH replacement therapy on insulin homeostasis in GHD subjects are still debated. Only a few studies investigated the effects of GHD and GH therapy on glucose metabolism in children.Objective: To evaluate the effects of GHD and GH treatment on glucose metabolism in a large cohort of GHD children before and after GH replacement therapy.</...

The two main subtypes of pseudohypoparathyroidism (PHP), PHP-Ia and -Ib, are caused by mutations in GNAS exons 1–13 and methylation defects in the imprinted GNAS cluster, respectively. PHP-Ia patients show Albright hereditary osteodystrophy (AHO) and resistance toward multiple hormones (PTH/TSH/GHRH/gonadotropins), whereas PHP-Ib patients classically display hormone resistance limited to PTH and TSH. Incoming data suggest that the two diseases share more genetic and clini...
