Background: This multi-country study, conducted in the USA, is also ongoing in France, Germany, Brazil and South Korea (52 healthcare professionals (HCPs) and 30 patients/caregivers in total). The new device consists of a reusable aluminium body and cap, with a multi-use cartridge system, viewing window, dose-display window, dose-selection knob and injection button.Method: Semi-structured 60-min qualitative interviews were conducted in six major US citie...

Background: Isolated persistence of Müllerian ducts in an otherwise normally virilised 46,XY newborn, a condition known as PMDS, is a disorder of sex development (DSD) due to a defect limited to AMH-dependent Müllerian duct regression.Objective and hypothesis: We report the case of a patient with PMDS and extremely low serum AMH in whom no mutations were detected in the AMH gene coding sequences. A single base deletion identified in th...

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...

Background and hypotheses: Recent results showing elevated tetrahydrocortisol/tetrahydrocorticosterone ratio (THFs/THE) in morning urines of diabetic children compared to controls suggest an increased nocturnal activity of 11 β-hydroxysteroid dehydrogenase type 1 (11β-HSD1). We made the hypothesis that a reduced inhibition of hepatic 11β-HSD1 activity by exogenous insulin, due to its subcutaneous (SC) administration and absence of first hepatic passage, could ex...

Background: Hematocolpos is a rare condition in young girls that can be caused by imperforated hymen or vaginal agenesis. It is usually diagnosed at early puberty with cyclic abdominal pain and amenorrhoea. Menarche is usually observed two years after the start of puberty; sometimes pre-menarcheal bleeding can occur, ranging from isolated premature menarche to spotting in course of puberty. In case of imperforated hymen or vaginal anomaly, a pre-menarcheal uterine bleeding can...

Background: We already described a partial IGF1 primary deficiency due to an exon 4 homozygous missense mutation (g.65941 G>A). A few patients are now described with a heterozygous IGF1 deletion or mutation, questioning about IGF1 haplo insufficiency role in short stature.Results: We describe a boy born from consanguineous parents, with an intra uterine growth restriction (IUGR). Birth weight: 2520 g (−1 SDS) birth length: 46 ...

Introduction: Primary Congenital Hypothyroidism (CH) is an abnormal function of the thyroid gland present at birth. Anomalies of thyroid function are usually classified between thyroid dysgenesis, corresponding to an abnormal embryological development of the thyroid, and CH with gland-in-situ (GIS), resulting from mutations in genes involved in thyroid hormone synthesis. We report 105 patients with CH with GIS that have been referred to Angers University Hospi...

Background: Metabolic syndrome and insulin resistance are well recognized in adult obesity. Their criteria and prevalence and are still controversial in children.Objective and hypotheses: To evaluate the prevalence and natural history of clinical and biological parameters of the metabolic syndrome in a pediatric cohort of obese subjects. To identify metabolically healthy subjects and the persistence of this phenotype over time.Meth...

Introduction: Despite improved therapy measures since 2014 the prevalence of overweight and obesity in Swiss adolescence stabilized on 19%. Particular challenges are lack of adherence to therapy in youth who are in difficult life situations or live further from specified centres. Therefore it is essential to find simple and novel therapeutic approaches. But although the number of digital based health information systems increases steadily, the effectiveness in reaching long te...

Background: Although growth hormone (GH) and the GH releasing hormone receptor (GHRHR) are known as etiologic factors in non-syndromic isolated growth hormone deficiency (IGHD), very few mutations have been identified in this rare condition (accounting for only 6–12.5% and 0–6.7% of IGHD cases depending on studies). The functional consequences of the identified variants have rarely been assessed.Objective and hypotheses: To assess the contribut...
