Introduction: In children, estradiol (E2) concentrations are 1000-times lower in comparison to their precursors, the androgens. Depending on sex, age, and pathology, plasma concentrations vary in a broad range. The sensitive and specific determination of E2 is a particular challenge in pediatric endocrinology. Here we report a female patient aged 12 6/12 years and Tanner stage B1 with a presumed diagnosis of ovarian insufficiency. She showed a very high E2 con...

Context: Newborns with Congenital hypogonadotropic hypogonadism (CHH) have an impaired postnatal activation of the gonadotropic axis. Substitutive therapy with recombinant gonadotropins can be proposed to mimic physiological male mini-puberty during the first months of life.Objective: To retrospectively compare the clinical (penile size, volume and testicular descent) and biological efficacy (serum concentrations of test...

Introduction: Growth retardation < –2 SDS is frequently observed in children with chronic kidney disease (CKD) and is a marker of severity of CKD. Recombinant human growth hormone (rhGH) treatment has been approved since 1995 in CKD patients. The aim of this study was to describe the growth outcomes and treatment patterns in children with congenital CKD.Methods: Patients were recruited from transplantation recor...

Introduction: Hypoglycemia is a common problem in neonatal period associated with adverse neurological outcome and brain injury if treatment was not provided. AAP and PES recommended screening for hypoglycemia only in newborns with risk factors but many others neonates may present episodes of asymptomatic hypoglycemia without any known risk factor.Objectives: To assess the incidence of hypoglycemia in healthy full term neonates without any risk factors i...

Background: Inappropriate management of illness/stress, accidental or deliberate insulin omission are some of the causes of Diabetes ketoacidosis (DKA) in patients with established diabetes. During illness, patients with type 1 diabetes are advised to monitor for hyperglycaemia and ketosis, maintain fluid intake and if required, to administer supplemental insulin. Previous studies have confirmed that comprehensive diabetes self- management education (DSME) programs on manageme...

Inactivating mutations of ß-cell KATP channels cause the most common and severe form of congenital hyperinsulinism (HI), a ß-cell disorder that results in dysregulated insulin secretion and persistent hypoglycemia. Children with KATPHI are typically unresponsive to diazoxide, the only FDA-approved drug for HI. Octreotide, an SST2-selective agonist peptide that inhibits insulin secretion, is used as second line therapy, but poor efficacy and SST2...

Introduction: 5α-reductase type 2 deficiency (5α--RD) and 17β-HSD type 3 deficiency (17β-HSDD) are rare differences/disorders of sex development (DSD) in which impairment of steroidogenic enzymes causes undervirilisation in patients with a 46,XY genotype. We aim to enlarge the limited knowledge on long-term gonadal function and gonadal pathology in these conditions.Methods: Data on phenotype, laborato...

Background: Specific measurement of low serum / plasma concentrations of 17β-estradiol (E2) is important in pre-pubertal and pubertal children in routine paediatric endocrinology. However, there is still a gap in available reference intervals (RIs) for E2 in paediatrics. The study was partially funded by the German Ministry of Health, grant number 2519FSB503.Objective: First, we technically developed a highly sensit...

Background: Shox gene, located on the short arm (p) of the X chromosome, is expressed in the growth plate cartilage in pre and post natal life. Whereas the dose dependent association between the number of active copies of the SHOX gene and height is well established, studies addressing a more subtle variability between the quality of fetal growth, the severity of post natal height deficit and karyotype subgroups in Turner syndrome (TS) are still limited....

Background: T3-P-GD, a severe, rare disorder well known in adults, has not previously been described in children. It is characterized by persistently high serum fT3 concentration and normal, or even low, fT4 concentration during drug treatment. This condition is associated with very high titers of TRAb and large goiters, but its pathogenesis remains unclear. The recognition of this form of GD in children is of particular importance, as higher antithyroid ...
