Objectives: Mutations in PTPN11 are known to be associated with Noonan syndrome (NS), accounting for approximately 50% of cases. Data from a non-interventional and phase 3 study of Norditropin (somatropin; Novo Nordisk A/S, Denmark) were used to assess the impact of PTPN11 mutation status on growth outcomes in children with NS receiving growth hormone therapy (GHT).Methods: The ANSWER (NCT01009905) prog...

Gonadotropin-releasing hormone (GnRH) is the master hormone regulating the reproductive axis and its pulsatile secretion is crucial for puberty onset and fertility. Disruption in GnRH neuron development or hypothalamic function can lead to absent or delayed puberty (DP) due to GnRH deficiency, with a phenotypic spectrum from severe delayed puberty to partial or complete Hypogonadotropic Hypogonadism (HH). HH can also be present as a shared trait with other neurodevelopmental d...

Background: Familial PTC manifesting in childhood has been described only in single cases, mainly in the context of rare syndromes (APC-associated-syndrome, PTEN-hamartoma syndromes etc). PTC in Grave’s disease (GD) has been described in adults, but not in familial cases including young children.Objective and hypotheses: We investigated the association of large metastatic papillary carcinoma (PTC) in a 10 years old female and her mother evolving rap...

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: Pubertal induction with incremental doses of oestrogen replacement is an important component of care offered to hypogonadal patients with Turner Syndrome (TS). Low dose oral ethinylestradiol (EE) has been extensively used in the UK but natural 17-β oestradiol (more physiological, cheaper and easily monitored in blood) is becoming increasingly popular.We undertook this audit to compare the efficacy and acceptability of...

Background: Turner syndrome (TS) is characterised by a wide phenotype and age at presentation. We reviewed our over-12s Turner clinic over a period of 10 years to evaluate pattern of diagnosis, co-morbidities and management.Subjects & Method: Retrospective data analysis of patients with TS who attended the over-12s clinic (2008-2017, n=28). Data is median (IQR) or mean±SD as appropriate.<p class...

Objectives: This retrospective and descriptive study aim to study the frequency of children who have a pubertal delay and who are followed at the Department of Pediatrics II at the Children’s Hospital of Rabat. Materials and Methods: Among 1850 records collected, 24 patient records that meet the criteria for inclusion. A delay in the appearance of sexual characters: the lack of breast development after the age of 13.5 years in the girl and the lack of inc...

Context: Assessment of breast development by physical examination(PE) can be difficult especially in overweight girls and in early stages. We aimed to study ultrasonography(USG) on evaluation of breast tissue in girls with breast development< 8 years of age.Patients and Methods: In this prospective study, 125 girls (age 7.1&pm;1.5 years) with early breast development were evaluated by breast USG for ultrasonographic b...

Background: Hereditary hypophosphatemia (HH), is a rare condition related to decreased renal tubular phosphate reabsorption. Although X-linked hypophosphatemia (PHEX mutation) is the most frequent cause of HH, recent advances in the next-generation sequencing (NGS) techniques enable the identification of various genetic etiologies. Our study aims to determine the molecular etiology of patients with hypophosphatemia and to identify new candidate genes....
