Introduction: Copeptin is a stable AVP surrogate, secreted in equimolar relationship, who has been proposed for the diagnosis of AVP-related hypo and hypernatremic disorders, i.e. the syndrome of inappropriate ADH secretions (SIADH), the cerebral/renal salt wasting syndrome (C/RSW) and diabetes insipidus (DI). Few data exist about the normal ranges for plasma copeptin levels in the pediatric age, reported between 2.4-8.6 pmol/L. The aim of this study is to rep...

Background: Increased risk of obesity and cardio-metabolic risk factors were reported in patients with classical congenital adrenal hyperplasia but little is known about adiposity among patients with non-classical congenital adrenal hyperplasia (NCCAH).Aim: To assess the prevalence of overweight, obesity and cardio-metabolic risk factors among NCCAH patients. Methods: A cross-sectional retrospective study of 114 NCCAH patients (93 ...

Background: Screening for congenital hypothyroidism (CH) with the possibility of an early treatment has transformed the outlook for children with CH. Despite the unquestioned public health success of newborn screening programs, the management of CH is still controversial. Most patients with positive screening have permanent hypothyroidism but some of them may have transient hyperthyreotropinemia, so it is important to identify these patients in order to avoid lifelong unnecess...

Background: ‘Dead in Bed syndrome’ mechanism in childhood diabetes remains unknown. The hypothesis is that a nocturnal hypoglycaemia could lead to arrhythmias related to abnormal ventricular repolarisation.Objective and hypotheses: To look for a relationship between spontaneous fluctuations of nocturnal glycaemia, ventricular repolarization and heart rate variability (HRV) in prepubertal children with type 1 diabetes.Meth...

Lipohypertrophy (LD) represents the most common cutaneous complication of insulin therapy worldwide. Epidemiological and clinical data on LD in children and adolescents with T1DM are growing since 2010 because of the introduction of new insulin analogs and the use of insulin pumps (CSII).Objectives and Methods: We performed an electronic search in PubMed, Google scholar and Web of Sciences to evaluate the global prevalence and possible r...

Introduction: Differences in sex development (DSD) comprise a heterogeneous group of congenital conditions that affect human sex determination and differentiation. We aimed to describe the clinical diagnoses of children with DSD who were referred to a pediatric tertiary center, and to examine trends in clinical features and management over three decades.Methods: This is a retrospective, cross-sectional study of children ...

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare disorder of neonatal salt loss unresponsive to mineralocorticoids, requiring salt supplementation. It results from resistance of kidney and/or other tissues to mineralocorticoids, arising from mutations in genes encoding mineralocorticoid receptor (MR: NR3C2; autosomal dominant), or epithelial sodium channel (ENaC) genes (SCNN1A/B/G; autosomal recessive). Milder clinical phenotype associates with ren...

During the pandemic, an increase in the cases of premature thelarche consultations was observed. Our group published a series in 2021 of 75 cases. This effect could have been caused by an increase in body fat mass in girls, suggesting a “trigger effect” in the activation of the gonadal axis, causing an increase in the number of cases of early puberty (SEEP Oviedo 2022). AMH has been correlated as a predictor of the moment of menarche (doi: 10.1515/jpem-2014-0521)</...

Background: OTX2 is expressed in the human brain and plays a key role in the eye development. OTX2 mutations are reported in patients with ano/microphtalmia, optic nerve or optic chiasm hypoplasia, ocular coloboma and retinal dystrophies, associated in some cases with brain or pituitary abnormalities.Objective and hypotheses: Most of OTX2 mutations are nonsense or frameshift, more rarely missense mutations occur.Method: We...

Background: French health authorities have developed a national program to organize outpatient care networks for the prevention and management of obesity in children and adolescents (Réseau de Prise en Charge de l’Obésité Pédiatrique (REPOP)). To date, REPOP Ile-de-France has more than 250 primary care physicians with dietitians, nurses, educators, and psychologists trained in the management of childhood obesity as part of a standard care pathway, work...
