Introduction: Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is a rare, autosomal disorder characterized by deficiency of cortisol and oftentimes aldosterone, elevated adrenocorticotropic hormone (ACTH), and excess androgen production. In a phase 2 study of adolescents with classic 21OHD, 14 days of treatment with the corticotropin-releasing factor type 1 receptor (CRF1) antagonist, crinecerfont, led to median percent red...

Background: Loss of function mutations in KISS1R, which encodes kisspeptin receptor have been reported in very few patients with normosmic isolated hypogonadotropic hypogonadism (nIHH).Objective and hypotheses: To describe the phenotype of the nIHH female patient with a novel homozygous KISS1R mutation and to characterize functionally this mutation. The patient was a 28 year-old Senegalese woman with primary amenorrhea. She was the seco...

Background: We compared continuous glucose monitoring (CGMS) (Medtronic) to oral glucose tolerance test (OGTT) and HbA1c in the follow-up of glycemic abnormality in an adolescent girl with morbid obesity and glycemic abnormalities before and after 2 months of partial gastrectomy. This 16-year-old adolescent girl presented with obesity (weight 98 kg, height 158 cm, BMI=39.2 kg/m2), acanthosis nigricans and nocturnal polyuria and polydipsia. Trials to reduce weight th...

Introduction: The aim of this study was to investigate the molecular genetic etiology and to determine the relationship between genotype and phenotype with targeted next-generation sequence (NGS)analysis.Method: Patients with a clinical diagnosis of OI were included in the study. Initially, mutations in COL1A1 and COL1A2 genes which are known to be most responsible for OI were investigated. In the second step, a targeted...

Introduction: The European Registries for Rare Endocrine Conditions (EuRRECa) project aims to support the needs of the endocrine and bone community by facilitating the collaboration between patients, health care professionals and researchers across Europe and beyond. It is a project funded by the European Union’s health programme and is the affiliated registry of the European Reference Network for Rare Endocrine Conditions (Endo-ERN). It consists of two r...

Background: Because of episodic secretion of gonadotropins (LH, and FSH), basal levels of these hormones can not objectively be assessed to differentiate delayed puberty in males.Objective and hypotheses: To assess the efficacy of the GnRH agonist (as spray) in diagnosing of delayed puberty in males.Method: Prepubertal males (n=18; age range 13.3–18.5 years) were studied; buserelin 0.15 (spray) μg was administere...

Background: X-linked hypophosphatemic rickets (XLH) represents the most common form of hypophosphatemia and leads to vitamin D resistant rickets in children. Even though cranial vault and craniovertebral anomalies of potential neurosurgical interest, namely early closure of the cranial sutures and Chiari type I malformation- have been observed in XLH patients their actual incidence is not established.Aim: Describe and analyze the incidence of cranial and...

Introduction: GDM prevalence is increasing worldwide. The aim of the study was to identify potentially modifiable predictors of adverse neonatal outcomes in women with GDM.Methods: This prospective observational study included 576 singleton multiethnic women diagnosed with GDM after 13 weeks of gestational age, followed in the Diabetes and Pregnancy Unit of the CHUV between 4/2012 and 2/2017. Predictors included HbA1c at booking after GDM diagnosis and a...

Background: Being born small for gestational age (SGA) has a negative effect on health-related quality of life (HRQoL) and self-perception. This might be more negatively influenced by postponement of puberty using additional gonadotropin-releasing hormone analogue (GnRHa) treatment.Methods: 154 adolescents born SGA participating in a large Dutch growth hormone (GH) trial (75 with 2 years of GnRHa-treatment) completed the TNO-AZL Adults Quality of Life qu...

Multiple Endocrine Neoplasia Type 1 (MEN1) is an inherited autosomal dominant disorder caused by mutations in the MEN1 tumor suppressor gene. Penetrance increases with age. It combines mainly hyperparathyroidism, adenomas of the pancreas and pituitary gland. The prevalence is about 2/100 000. Diagnosis in children is rare except in the case of family screening. We report the diagnosis of a familial MEN1 whose index case was an adolescent girl investigated because of hypoglycae...
