In a retrospective study (1), we found that a GH<6.5 μg/L, IGF-I-WHO87/518 <30 μg/L and IGFBP-3<0.8 μg/mL confirmed GHD diagnosis with high diagnostic accuracy in neonates with clinical suspicion of GHD. GH and insulin negatively regulate IGFBP-2, and it was proposed to reflect GH status in the diagnostic work-out of GHD in childhood and adults. The accuracy of IGFBP-2 has not been set for neonates.Objective: To prospectively v...

Background: Neuroendocrine tumors from adrenal and extra-adrenal chromaffin cells are characterized by overproduction of catecholamines (CA), leading to the increase of urinary O-methylated metabolites (uO-Met) excretion, reliable biomarkers for the initial screening, diagnosis and monitoring of patients with pheochromocytoma and paragangliomas (PPGLs).Objective: To develop and validate a UHPLC-MS/MS method for the simul...

Due to the increase in prevalence of childhood obesity, more obese children are referred to the endocrinologist for the hypothalamus-hypophysis-adrenal axis assessment. The circadian rhythm (CR) of cortisol in saliva (SAF) may constitute a non-invasive, first line test to exclude hypercortisolism on obese children.Aim: To evaluate possible disturbances of CR of SAF in obese children with clinical signs of hypercortisolism.<p class="a...

Aim: To determine Sertoli cell function at diagnosis and after 3 months of chemotherapy.Methods: A prospective cohort study was performed including children with acute lymphoblastic leukaemia, acute myeloid leukaemia, or non-Hodgkin lymphoma. Serum levels of AMH were evaluated at diagnosis and after 3 months during chemotherapy. Results were analysed as standard deviation scores according to pubertal stage and expressed ...
