Background: Micronodular bilateral adrenal hyperplasia (MiBAH) is a rare cause of adrenal Cushing syndrome (CS) that may be subdivided in two main entities: primary pigmented nodular adrenocortical disease (PPNAD) and isolated micronodular adrenocortical disease (i-MAD). The most common presentation of MiBAH is familial PPNAD as part of Carney complex (CNC). The underlying genetic defect in most forms of PPNAD is inactivating germline mutations of the PRKAR1A ...

Summary: Severe obesity with various complications is a growing public health problem in childhood. Due to the lack of available hygienic and dietary therapeutic solutions, bariatric surgery has become, in recent years, one of the only effective treatments for severe obesity to induce persistant weight loss and reduce complications.Material and method: We analyzed a cohort of 162 patients followed in the specialized obes...

Background/Aim: 25 to 40% of children with well-controlled X-linked hypophosphatemia (XLH) show linear growth failure, despite optimal conventional treatment (oral phosphate supplementation and active forms of vitamin D) with final height -2 SDS. Recombinant human growth hormone (rhGH) may be an adjuvant treatment of the growth retardation in these patients. Therefore, the main objective of this study was to describe how rhGH treatment improves final heigh...

Objectives: Differentiated thyroid cancer (DTC) has shown increasing incidence in children and young people <19 years (CYP), and CYP present with more extensive disease than in adults and are at risk of long-term morbidity. A paucity of randomised controlled trials in the field has led to a lack of consensus on how these children should best be managed. These Children’s Cancer and Leukaemia Group and British Society for Paediatric Endocrinology and Diabetes commission...

Background: Silver-Russell syndrome (SRS) (mainly secondary to 11p15 molecular disruption) and Temple syndrome (TS) (secondary to 14q32.2 molecular disruption) are imprinting disorders with very close phenotypic (prenatal and postnatal growth retardation, early feeding difficulties, early puberty) and molecular anomalies. Our objective was to describe the clinical overlap between SRS and TS and to extensively study the molecular aspects of patients with 14q32.2 molecular disru...

Introduction: Glucagon-like peptide 1 (GLP-1) receptor agonists have been successfully used in adults with hypothalamic obesity, showing a BMI decrease and metabolic profile improvement. Data on GLP-1 receptor agonist treatment for children and adolescents is limited. Herein, we present a clinical case of a male adolescent treated with GLP-1 receptor agonist for hypothalamic obesity, secondary to craniopharyngioma.Case report: A 15.8 year-old boy (Height...

Background: Incidence of hypospadias varies considerably across countries, ranging from 4 to 43 cases per 10,000 births. Environmental factors might explain these differences. The classical approach is to use case-control studies to identify these factors. However, this approach suffers from the unavoidable arbitrariness of the definition of controls, and of recall bias.Objective and hypotheses: To identify environmental markers of the place of birth of ...

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...

Background: POU1F1 encodes a pituitary-specific homeodomain transcription factor that is crucial for development and differentiation of anterior pituitary cell types. Mutations in this gene result in GH, TSH and prolactin (PRL) deficiencies.Objective and hypotheses: To describe a male newborn of a mother with known dominant p.R271W mutation in the POU1F1 gene.Methods: Case report with clinical follow up, endocrine investigations, n...

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....
