Objectives: Achondroplasia (ACH), caused by a mutation in the fibroblast growth factor receptor 3 gene (FGFR3), leads to inhibition of endochondral bone growth. Vosoritide is a biological analogue of C-type natriuretic peptide (CNP), a potent stimulator of endochondral bone growth. A Phase 2, open-label, sequential cohort, dose-escalation study was conducted to evaluate the safety, tolerability, and efficacy of vosoritide for 24 months in children with ACH aged 5&#150...

Introduction: Premature pubarche is the most frequent diagnosis when children present moderate pubic hair development, but other diagnosis must be ruled out. We report the case of a child with premature pubarche with hormonal results in the physiological range, corresponding to an adrenal tumor.Observation: A girl aged 6.8 years consulted for precocious pubertal development (pubic hair stage 3, breast stage 2), with moderate acne. There was no virilizati...

Introduction: Ovarian stimulation syndrome (OSS) in an infrequent disorder, in preterm infants under 30 weeks gestation. The are very few cases described in the literature. The immaturity, lack of gonadal axis feed-back or mutations in the FSH receptor genes, may explain its physiopathology. We present the case of a 26-week neonate with this syndrome.Case summary: 26-week newborn with extremely low weight (460g) born by emergency cesarean section due to ...

Background/Aim: Diabetes with extra-pancreatic features in children can have a monogenic aetiology. Single gene testing is undertaken when children present with the characteristic clinical features suggestive of the underlying aetiology. We aim to assess the utility of comprehensive genetic testing for all monogenic diabetes genes in children with diabetes and any non-autoimmune extra-pancreatic features from a population with a high rate of consanguinity.<p class="abstext...

Introduction: Noonan syndrome (NS) is an autosomal dominant disorder that involving multiple organ systems, with an incidence of 1:1,000 to 1:2,500.The clinical features as short stature, dysmorphic facial features, congenital heart defects most commonly pulmonary valve stenosis, typical chest, cryptorchidism. The PTPN11 gene is located on the long arm of chromosome 12q24.1 and encodes for the non-receptor protein tyrosine phosphatase SHP-2 (SHP2), generating ...

Background: Prader-Willi syndrome (PWS) is a complex, multisystem disorder and is the most frequent cause of syndromic obesity that arises from lack of expression of paternally inherited imprinted genes on chromosome 15q11-q13. Its major clinical features include neonatal hypotonia, short stature, developmental delay, behavioral abnormalities, hyperphagia, childhood onset obesity, hypothalamic hypogonadism, and characteristic appearance.Case history: We ...

Background: Patients with Turner’s syndrome (TS) develop osteoporosis, resulting from chromosomal deficiency and estrogen deficiency by gonadal dysgenesis.Objective and hypotheses: The aim of this study was to assess bone mineral density (BMD) and parameters of bone remodeling during somatropin therapy in prepubertal girls with TS.Population and/or methods: We examined 22 girls with TS of the age of 11–15 years (the mean ...

Background: Prader-Willi syndrome (PWS) is a complex multisystem genetic disorder arising from lack of expression of paternally inherited imprinted genes on chromosome 15q11–q13. Hyperphagia represents one of the most serious symptoms of the PWS, leading to develop premature mortality.Objective and hypotheses: To compare orexigenic (ghrelin) and anorexigenic factor (brain derived neurotrophic factor (BDNF)) concentration in non-GH-treated obese pati...

Background: The gastrointestinal (GI) tract plays a central role in maintaining energy balance and body weight regulation. These functions are mediated by the secretion of gut hormones, including ghrelin, cholecystokinin (CCK), peptide YY(PYY), oxyntomodulin (OXM) and many other hormones. Some of them are orexigenic hormones that promote food intake, while others act as satiety signals and enhance insulin secretion from the pancreatic beta cells. Current evide...

Background: Ambulatory blood pressure monitoring (ABPM) permits the observation of blood pressure (BP) in a nonmedical environment. In adults, ABPM is better related to renal damage and cardiovascular morbidity than office BP readings. In early stages of type 1 diabetes (T1DM), the role of ABPM is still controversial.Objective and hypotheses: To detect blood pressure abnormalities using 24-h ABPM in children and adolescents with T1DM and to determine the...
