Background: Concerns about a child's growth are one of the most common topics parents express during pediatric visits and are a leading cause for referral to a pediatric endocrinologist. For the general pediatric, when short stature is diagnosed, its clinical management remains a challenge.Objective: The aim of the study was to approach and understand the perception from the general pediatrician about short stature,...

Background: Septo-optic dysplasia (SOD) is a rare condition diagnosed in children with two or more of the following: hypopituitarism, midline brain abnormalities, and optic nerve hypoplasia (ONH). Children with SOD experience varied visual impairment and endocrine dysfunction. Autistic-like behaviours have been reported, however the nature and prevalence of these neurobehavioural impairments remain to be fully understood. The present systematic review aimed to...

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...

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. ...

Background/Aims: Length and weight of all children in Flanders are monitored every three years at school from the age of 3 years. The current criteria used for referral to specialized care are: height SDS < -2.5, height SDS between -2 and -2.5 SDS with a height SDS adjusted for parental height < -1.64, or a decrease in height SDS of more than 1 SDS in the past 3 years. The aim of this study is to investigate the sensitivity of the Flemish referral criter...

Background: Insulin Tolerance tests (ITT) have long been considered the gold standard for dynamic function testing of the hypothalamo-pituitary-adrenal (HPA) axis. Sub-optimal cortisol responses during an ITT in children may be found in children during ITT without a previous clinical suspicion of Adrenal insufficiency (AI). It is not clear what the clinical significance of this is and whether all of these children require formal synacthen testing.<p class=...

Background: The methylation of IGF1 promoter P2 was reported to negatively correlate with serum IGF-1 concentration and rhGH treatment response in children with idiopathic short stature. These findings have not yet been confirmed.Objective: This study aimed to determine IGF1 promoter P2 methylation in short children treated with rhGH and correlate clinical parameters with the methylation status. In addition, long-term st...
