Central diabetes insipidus (CDI) at neonatal age may occur in the setting of intracranial abnormalities that affect the hypothalamus-pituitary system. These conditions are characterized by defective production, transport or secretion of antidiuretic hormone (ADH). This results in inappropriately low ADH levels in the setting of increased plasma osmolality. We present the case of an infant born by C-section at 38 weeks of gestation, with bilateral cheilognatopalatoschisis, naso...

Hyperinsulinemic hypoglycemia (HH) is common in newborns. If hypoglycemia occurs after the first 48 hours following birth, it may be a sign of an underlying condition. We present the case of a baby girl born at 38 weeks of pregnancy, with good adaptation to extrauterine life and blood glucose of 60 mg/dl in the first days of birth. Approximately 2 days after discharge, she was addressed at the emergency unit because of food refusal for approximately 30 hours, with a blood suga...

Introduction: Mutations in the GH1 promoter are a rare cause of isolated GH deficiency (IGHD). In order to find the molecular cause of short stature due to IGHD, three siblings (2 M) born to consanguineous parents without mutations in the GHRHR and GH1 coding regions were screened for mutations in the GH1 promoter and locus control region. All patients harbored two variants (c.−123T>C and −161C>T) in homozygous state in the GH1 promoter, not found in 100 co...

Background: Isolated Growth Hormone Deficiency (IGHD) is usually associated with a delayed bone age. A genetic cause for IGHD is more frequently found in patients with familial cases and/or consanguineous parents.Objective and hypotheses: To diagnose the genetic cause of IGHD and clarify the unusual clinical presentation of advanced bone age in one patient born to consanguineous parents.Method: Sanger sequencing of GH1, <e...

Background: A virus initially considered benign in this age group, SARS-COV-2 has recently been associated with Pediatric Multisystemic Inflammatory Syndrome (PIMS), temporarily associated with COVID-19, a syndrome whose diagnostic determination has a vital relevance since it imposes unfavorable outcomes. This study aims to describe the sociodemographic characteristics of PIMS in Brazil and the factors associated with death by this syndrome.<p class="abste...

Case Report: Patient 1: a 3.6-yr-old girl presented with very severe hypertriglyceridemia (serum triglyceride level >1000mg/dL) in random sampling in the first year of life. She presented with recurring episodes of abdominal pain, and splenomegaly. There is no history of consanguineous marriage. Maternal and paternal family had history of coronary events at an early age. A genetic panel showed homozygous variant chr8:19.953.365 C>T (p.Ala162Val) in the l...

Introduction: In youth, primary ovarian insufficiency (POI) is due to genetic, autoimmune, iatrogenic, and idiopathic etiologies. When POI is diagnosed early with evidence of an ovarian reserve, fertility preservation can be offered. When the girl is premenarchal, the preferred fertility preservation method is ovarian tissue cryopreservation (OTC) containing primordial follicles. In the past, when OTC was performed in an unselected group of children and adoles...

Recently, we identified Neuritin 1 (NRN1) as preferentially expressed in human white compared to brown adipocyte progenitor cells. In mice, Nrn1 deficiency leads to a reduction in body weight, indicating that it might regulate body weight. In this study, we aim to address the function of NRN1 regarding adipocyte metabolism in vitro and in vivo. We used human SGBS preadipocytes as an in vitro model system. NRN1-deficient cells were generated using len...

Background: The French population of the SAGhE study showed an increased morbidity and mortality due to cerebrovascular disease in growth hormone (GH) treated subjects compared to the general population. Cerebrovascular health can be assessed using neuroimaging markers on MRI. One of the markers is white matter hyperintensity (WMH).Objective: To assess cerebrovascular health by scoring WMH on MRI in young adults born sma...

Introduction: When used to treat obesity, glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1RA) improve both BMI and metabolic health. Liraglutide is approved by both the EMA and FDA for the treatment of pediatric obesity, from 12 years and older. However, 26 weeks after discontinuation of liraglutide, the weight lost during treatment is regained. Prolonged exogenous stimulation of hormone-specific receptors may influence endogenous hormonal regulation. ...
