Background and Aim: Recombinant growth hormone (GH) is reimbursed for the treatment of short stature (<-2.5 Z-score) in children born small for gestational age (SGA) without postnatal growth, aged ≥ 4 years with a height Z-score >1 below mid-parental height (MPH). We wanted to determine the current GH prescribing practices by pediatric endocrinologists (PE) for SGA related short stature and document the percentages of treated children at risk for...

Introduction: Among children with short stature, some show persistent IGF-I levels <-2.0 SDS despite a normal growth hormone (GH) response in a stimulation test. This may be caused by conditions that could benefit from recombinant human GH (rhGH) therapy (e.g. GH neurosecretory dysfunction, bioinactive GH, partial GH insensitivity). Therefore, the IGF-I generation test (IGFIGT) was implemented in 2006 using a national, standardized protocol. Children with a...

Background: The association between HNF1A-MODY and vascular complications including stroke has previously been identified in adults but to date there have been no reported paediatric cases published.Description: We present the case of an Eritrean 13-year-old girl, who was admitted with an acute ischaemic stroke, on a background of Diabetes Mellitus (Presumed Type 1) diagnosed the previous year. Aside from being on multip...

Context: We previously observed that continuous subcutaneous infusion (CSI) of gonadotropins in infants with congenital hypogonadotropic hypogonadism (CHH) can mimic the hormonal pattern of minipuberty.Objective: Describe the peripubertal outcome in gonadotropins CSI treated patients.Patients: A retrospective study was realised in Bicetre Hospital between 2004 and 2022. Follow-up d...

Context: Neonatal hypoglycemia due to congenital hyperinsulinism (CHI) is a potentially life-threatening condition. Severe forms of CHI, caused by autosomal recessive variants in KATP channel subunit genes (ABCC8, KCNJ11), are more prevalent in regions with high consanguinity. These regions also have a high neonatal mortality rate with many deaths remaining unexplained.Patients and Methods: We analyze...

Differences of sex development (DSD) occur in about 1 in 3000 newborns in Switzerland. The indication and timing of genitoplasty in children with DSDs is a complex issue. In 2012 the Swiss National Advisory Commission on Biomedical Ethics published its position against early irreversible interventions in order to "normalize" the aspect of the external genitalia.We report the case of a child with a 46,XX DSD due to a classical form of congenital a...

Introduction / aim: Neonatal diabetes owned to potassium channel mutation can be successfully treated by sulfonylureas (SU). No study has reported SU efficiency according to the genotype.Method: Review of literature conducted in accordance with the control criteria of Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Search engine used: PubMed and the Cochrane Library database. Selection of clinical report, case reviews and met...

Background: Variants in the estrogen receptor α (ESR1) have previously been described in male and female patients presenting with estrogen resistance. Estrogen resistance is characterized by delayed bone-age, early-onset osteoporosis, delayed puberty and multicystic ovaries in women. So far, no clinical consequences of variants in the estrogen receptor β (ESR2) have been reported in 46,XX patients, although ESR2 variants have previously been implicated in 46,XY DSD p...

Background: Congenital Central Hypoventilation Syndrome (CCHS) is a rare disorder of respiratory control resulting from heterozygous polyalanine repeat expansions within the Paired-Like Homeobox 2B (PHOX2B) gene. A hypoglycaemic seizure in a 4-year-old girl with CCHS, lead to a more detailed examination of glycaemic control in a cohort of children with CCHS.Objective: To describe glucose homeostasis in children with CCHS.M...

Introduction: X-linked hypophosphatemic rickets (XLHR) is due to mutations in the PHEX gene inducing increased levels of fibroblast growth factor 23 (FGF23), phosphate wasting, hence rickets. FGF23 is suspected to be as an important metabolic regulator of glucose and lipid metabolism.Objective: To describe the metabolic profile (body mass index, blood pressure, glucid and lipid profile) in patients with XLHR and evaluate the correlation between FGF23 lev...
