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 ...

Background: Obesity and unfavorable metabolic profile (insulin resistance and/or dyslipidemia) are frequently observed in Polycystic Ovarian Syndrome in Adolescents (PCOS) girls regardless of weight.Objective and hypotheses: To evaluate clinical features and metabolic profile in PCOS adolescents, before, during and after Oral Contraceptive (OC) treatment.Method: We performed a retrospective study on 51 girls with PCOS diagnosed acc...

Introduction: PGD is characterized by hyperthyroidism and antibodies against the TSH receptor (TSHRAB). Reported annual incidence is 4,58/100,000.Objective: To describe an Argentinean cohort with PGD followed between 2006 and 2020 at the Ricardo Gutierrez Children’s Hospital.Material and Methods: Retrospective study of 69 patients, who were treated initially with antithyroid ...

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...

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...

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...

Background: Studies about thyroid function following hemithyroidectomy are scarce in the literature and no studies include pediatric population.Objective: To describe thyroid function in pediatric patients who underwent a hemithyroidectomy.Design: Retrospective cohort study.Patients and Methods: Among the 38 patients who underwent hemithyroid...

Background: Primary Addison’s disease (AD) is a rare endocrine condition, with reduced or absent secretion of adrenal hormones. Steroid replacement therapy normalizes endocrine assess and the quality of life. More than a half of patients display additional autoimmune conditions, which represent a considerable clinical concern.Objective and hypotheses: Antiparietal cells antibodies (APC-Ab) are commonly found in patients with autoimmune Addison’...

Background: Childhood onset PTC has a more aggressive presentation but no overall increase in mortality compared to adults.Objective: To characterize a pediatric cohort with PTC at diagnosis using the American Thyroid Association (ATA) Initial Risk Stratification (IRS) and to evaluate the response to initial treatment until 3 years based on the modified ATA Dynamic Risk Stratification (DRS) for adults.<p class="abste...

Background: Puberty is associated with a physiological decline in insulin sensitivity. Overweight and obesity are common among girls with Central Precocious Puberty (CPP). CPP and early menarche have been considered as risk factors for obesity and cardiovascular diseases during adulthood. Besides, concern has been raised by the potential impact of GnRH analogues (GnRH-a) treatment on body weight and metabolic profile.Objective and hypotheses: To evaluate...
