Background: Neonatal hyperinsulinism is the most frequent cause of neonatal recurrent hypoglycaemia. The persistent form can be explained by mutations of genes involved in beta cell function, whereas the transient form can occur in case of prematurity, low birth weight, macrosomia, perinatal hypoxia, and maternal diabetes.Objective and hypotheses: As we observed an increase in the incidence of neonatal hyperinsulinism, we hypothesized that potential mate...

X-linked hypophosphatemia (XLH) is diagnosed in children with clinical and or radiological signs of rickets, impaired growth velocity, low serum phosphate levels associated with renal phosphate wasting, in the absence of vitamin D or calcium deficiency. Conventional treatment is made of phosphate and active vitamin D. However, nephrocalcinosis has been identified as a complication of this therapy. Its prevalence is about 25-40% in adult XLH treated patients. It was never c...

Background: Vitamin D may have cardio-protective properties due to its biological actions. In children, observational studies linking actual vitamin D level and blood pressure have yielded conflicting results. Whether early life vitamin D exposure may elicit a programming effect on later systolic blood pressure (SBP) and diastolic blood pressure (DBP) needs further investigation.Objective and hypotheses: We investigated whether higher levels of cord 25-h...

Background: Traumatic brain injury (TBI) is common in childhood and can induce pituitary defects. Long-term endocrine consequences are missing.Objective and hypotheses: To determine in a prospective way if pediatric patients with a personal history of TBI developed long term pituitary deficiency independently of the results of the early hormonal investigation.Method: Prospective follow-up of an initial cohort of subjects (0–15...

Background: Traumatic brain injury (TBI) is common in childhood but long-term endocrine consequences are yet to be documented by prospective data.Objective and hypotheses: We have previously demonstrated in prospective study that, 1 year after severe accidental TBI (ATBI) or inflicted TBI (ITBI), children and adolescents may present pituitary and growth hormone (GH) dysfunction. We present here the follow-up of this population to determine whether or not...

Background: Vitamin D deficiency in children clinically manifests as rickets causing growth impairment and bowing of the long bones, potentially increasing the ratio between crown-rump length and length (CRL:L) or sitting height and height (SH:H).Objective and hypotheses: We investigated whether CRL:L in 19-months-olds and SH:H in 36-months-olds were lower with higher cord 25hydroxyvitamin D (25OHD).Method: Participants were includ...

Background: Children born small for gestational age (SGA) exhibit wide variations in the activity of growth hormone (GH)/insulin–like growth factor–I (IGF-I) axis and this heterogeneity may result in supra physiological concentrations of IGF-I during GH treatment. The long-term effects of elevated IGF-I levels has been a matter of concern. We explored the variations in total IGF-I and bioactive IGF-I and the associations with growth and glucose metab...

Background: A common polymorphism in the growth hormone receptor gene (d3-GHR) was found to be associated with pre- and postnatal growth and GH-induced growth. D3-GHR was associated with glucose metabolism in adults with GHD and acromegaly, but this has not previously been explored in children.Objective and hypotheses: We examined the impact of the GHR-exon-3 deletion on glucose metabolism and anthropometrics in short SGA children before and following 1 ...

Background: A 33-year-old woman with a history of adrenocortical carcinoma (ACC), surgically treated aged 4, presented for prenatal screening at 20 weeks gestation. Ultrasound examination identified that the female foetus had a 3-cm adrenal lesion. She had a positive family history for multiple-endocrine-neoplasia-type 2/MEN2 (paternal grandmother) and her father’s cousin was diagnosed with ACC and Li-Fraumeni syndrome (LFS) at 30 year old. Calcitonin, PTH and cathecholam...

Introduction: Central Precocious Puberty (CPP) results from the premature activation of the hypothalamic-pituitary-gonadal axis. Is defined by the onset of secondary sexual characters before 8-years-old in girls and 9-years-old in boys. It’s associated with accelerated growth and advanced bone maturation and can lead to early epiphyseal fusion and reduced final height at adult age.Aims: To evaluate and compare the ...
