Background: Children with Asthma who do not respond to first-line therapy may need inhaled corticosteroid-long-acting beta agonist combination (ICS-LABA) therapy. Adrenal insufficiency (AI) due to adrenal suppression is a recognized but relatively uncommon side effect of ICS. An increase in suspected cases of AI associated with one particular ICS-LABA, mometasone-formoterol (Zenhale) was observed at a tertiary care Asthma clinic over a 6-month period.Obj...

Background: McCune–Albright Syndrome is a combination of polyostotic fibrous dysplasia (BFD), café’-au-lait skin pigmentation and hyperfunctioning endocrinopathies. It results from postzygotic mutations in a-subunit of the Gsalfa protein and the consequent phenotype is a mosaic with high degree of clinical variability.Objective and hypotheses: The aim of the study is determine prevalence and characteristics of GH hypersecretion (GHH) in MA...

Background: Vaptans, vasopressin receptor 2 antagonist, are used in adults to treat hyponatremia associated with congestive heart failure, cirrhosis, and the syndrome of inappropriate antidiuretic hormone (SIADH). To date, in paediatric patients with SIADH there are few data about use of vaptans, still considered off-label.Case presentation 1: A 9-yo female with surgically treated suprasellar astrocitoma developed chronic hyponatremia (121–128 mmol/...

Introduction: Graves-Basedow disease (GD) is the most common cause of thyrotoxicosis in pediatric age. Multi-factorial pathogenesis stand on the basis of the autoimmune disorder activation, leading to lymphocyte imbalance that include increased CD4+ and CD8+ subtypes, increased CD4+/CD8+ ratio and B cells dysregulation. The aim of this study is to determine the potential prognostic value of lymphocyte population parameters in pediatric GD.<p class="abstext...

Introduction: Precocious Peripheral Puberty (PPP) due to autonomous ovarian activation is the most frequent endocrinopathy in girls with McCune-Albright Syndrome (MAS). Main goals of treatment for PPP are to reduce signs of estrogen exposure, also improving final height, and mitigate secondary psychological influence of sexual hormones exposure. This retrospective study analyzes the long-term safety and efficacy of letrozole treatment in a cohort of girls with...

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...

Aim: to assess and follow-up anthropometric and biochemical parameters in patients with abdominal obesity after a lifestyle intervention.Patients, Material and Methods: 122 children and adolescents with abdominal obesity, aged 7 to 16 years, were included in a control randomized intervention study (NCT031472). Abdominal obesity was diagnosed using the waist circumference. The intervention included an intensive phase duri...

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 ...

Introduction: Type 1 Diabetes Mellitus (DM1) is an autoimmune disease resulting from the destruction of pancreatic β cells. After the diagnosis, up to 80% of patients spontaneously experience partial remission (PR) for months. New biomarkers are being studied, such as the betatrophin protein (ANGPTL8) of unknown function, but which could be involved in the evolution of DM1, in this phase of RP and even used as a therapeutic target.Methods: Observati...

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...
