Background: Achondroplasia (ACH), the most common short-limbed skeletal dysplasia, is characterized by impaired endochondral ossification resulting from gain-of-function pathogenic variants in the fibroblast growth factor receptor 3 (FGFR3) gene, a negative regulator of endochondral bone growth. People with ACH are at risk for several significant co-morbidities, including brainstem compression due to foramen magnum stenosis, sleep-disordered breathing, chronic...

La puberté précoce est définie comme le développement des caractéristiques sexuelles avant l'âge de 8 ans chez les filles et de 9,5 ans chez les garçons. L'objectif de notre étude était de calculer la prévalence de la puberté précoce en consultation spécialisée et de décrire le profil clinique, paraclinique, étiologique et de prise en charge ainsi que la qua...

Introduction: Delayed puberty is defined as the absence of the development of sexual characteristics beyond the age of 14 for boys and 13 for girls. To better understand this pathology, we conducted a retrospective study over a period of 7 years; between 2013 and 2020, involving 11 patients with a delayed puberty, followed by a pediatric endocrinology consultation at the children’s hospital Ibn Sina in Rabat.Patients:</stro...

Background: Treatment of CAH in children is compromised by the pharmacokinetic of available hydrocortisone (HC) preparations resulting in un-physiological early morning rise of ACTH followed by elevated androgens. HC substitution usually follows a fixed dosing scheme (50%–25%–25%) monitored by blood sampling.Objective and hypotheses: We describe the individualized optimization of HC treatment by 17-OHP saliva profiles and the effects of the res...

Handling diabetes at a very early age is difficult, even more when a complementary diet has not yet started. There is increasing evidence supporting the use of CSII in infants but some tricks could be useful.Infant 1: 10 mo, admitted in cardiac arrest. ROSC after 3 minutes, severe DKA (pH 6,95). Transferred to PICU, received also plasma transfusions. Day 2: CGM Dexcom G6 was started and tests for pancreatic autoimmunity and genetic of ne...

Background: GH has a strong positive influence on bone stimulating both bone elongation and increase in size by enhancing the accrual of trabecular and cortical bone up to the attainment of peak bone mass in young adult.Aim of the study: We compared the effect of two different GH dosages on statural growth and bone geometry in two groups of GH-deficient children at final height. Data has been collected retrospectively from 1994 to 2013.<p class="abst...

Background: Beckwith–Wiedemann syndrome (BWS) is an overgrowth syndrome with an increased risk of embryonic tumors during early childhood. About 80% of patients with BWS show a molecular defect in the 11p15 imprinted region. Loss of methylation at the imprinting control region 2 (ICR2) is the most frequent defect which leads to a loss of expression of the CDKN1C gene, increasing cell proliferation. These epigenetic defects occur mostly as a mosaic event.<p cl...

Background: Impaired linear growth and low IGF1 levels, strictly related to poor glycemic control have been reported in children with type 1 diabetes (T1DM).Objective and hypotheses: We studied growth and growth factors in 91 T1DM young patients, 54 males (age: 11.73±3 years, disease duration: 5.2±2.9 years). All subjects were on intensive insulin therapy: 72 children by multiple injection therapy (MI), 19 children by continuous subcutaneous in...

Background: Idiopathic ketotic hypoglycaemia (IKH) is an exclusion diagnosis and the most common cause of hypoglycaemia in childhood. Glycogen Storage disease (GSD) type IX comprises one quarter of all GSD’s. GSDIXa, encoded by PHKA2, is the most frequent subtype.Objective: To investigate whether IKH may be undiagnosed GSDIXa.Methods: Hospital file review and next generation sequence 29 gene GSD-panel.<p class="ab...
