Background: We have previously shown radioimmunoassay (RIA) and gas chromatography-tandem mass spectrometry (GC-MS/MS) to be comparable when analyzing estradiol and testosterone concentrations in prepubertal and pubertal children. However, the reliability for steroid hormone determination with RIA in umbilical cord blood is not known. In general, older studies using RIA show higher values of testosterone, than more recent ones using MS/MS.Patients and me...

Background: Small for gestational age (SGA) children have reportedly increased DHEAS levels during prepubertal years. However, steroid hormones have not been followed longitudinally in a healthy population compared to body composition.Aims and objectives: To evaluate steroid hormone patterns in prepubertal children correlated to visceral fat measures.Methods: Body composition was investigated with magnetic resonance (MR) of truncal...
