Background: Congenital hypothyroidism (CH) comprises a heterogeneous group of disorders that includes diseases of the hypothalamo-hypophyseal system. The latter are missed on TSH based screening programs leading to increased morbidity and mortality. Additional T4 determinations, allows an early detection of CH of central origin (CH-C).Objective and hypotheses: To report the findings of a neonatal screening program based on determination of TSH...

ERF protein is a major binding target of ERK1/2 kinases, key effectors of the RAS–MEK–ERK signaling cascade. ERF has a role as a negative transcriptional regulator of RAS/MAPK mitogenic pathway (1) and, in theory, a loss-of-function mutation (LOF) in ERF could cause a Rasopathy phenotype. To date, LOF variants of ERF have been reported in 45 individuals with craniosynostosis but without a Noonan-like phenotype. There is only one case report describing a patient wit...

Background: The aim of our study is to determine the relation of vitamin D levels (25(OH)VD) with body-mass index (BMI), age and month of extraction in pediatric patients.Materials and Methods: We present a retrospective review of medical records of patients under 18 years of age visited by the Children's Endocrinology Service (overweight and obesity) and ambulatory pediatrics (healthy and normal weight children) at ...

Background: The ECOS observational study in Spain (NCT01376921) aims to evaluate adherence to r-hGH therapy prescribed via the easypod™ electromechanical auto-injector device and to analyse factors that may influence adherence in paediatric patients. Easypod™ administers pre-set doses of Saizen® r-hGH and stores accurate records of each dose and injection taken, which can then be shared with the HCP for evaluation of the patient’s adherence.<...

Background: Severe deficiency of 11β-hydroxysteroid dehydrogenase type 2 (11βHSD2) triggers activation of mineralocorticoid receptor (MR) by cortisol and causing apparent mineralocorticoid excess (AME) syndrome characterized mostly by low-renin arterial hypertension and hypokalemia. In 2003, we studied a patient with AME (3 years-old) having two homozygous mutation, D223N (rs121917833) and a SNP C>T in intron 3 (rs376023420) (Carvajal et al. JCEM 2003).<p cla...

Introduction: Achondroplasia is caused by a pathogenic mutation in the FGFR3 gene, leading to impaired endochondral bone growth and multiple medical complications. Vosoritide (once daily, subcutaneous injection) has recently been approved by the European Medicines Agency (EMA) for treating achondroplasia in patients aged ≥2 years until closure of epiphyses. It has been made available in France via an early access program, a cohort Temporary Authorization fo...

Silver-Russell syndrome (SRS) is an epigenetic disorder characterized by severe intrauterine and postnatal growth retardation and typical dysmorphic features. The most common genetic abnormalities are 11p15 ICR1 loss of methylation, (11p15 LOM) and maternal uniparental disomy of chromosome 7 (mUPD7). There is little information on cognitive development in SRS patients and no neuroradiological studies are available so far. Global developmental delay and requirement for speech t...

We describe a female neonate born from consanguineous parents who presented at birth with respiratory distress and severe hypoglycemia. At six months of age, the child was admitted to the Intensive care Unit because of two critical episodes characterized by fever and loss of consciousness. Child condition were critical and suggestive of sepsis, but blood tests showed severe hypoglycemia (19 mg/dl), hyponatremia (Na 132 mmol/l), compensated metabolic acidosis and increased infl...

Introduction: Achondroplasia is the most common skeletal dysplasia, in which the main clinical feature is short stature. Vosoritide, the first specific treatment for achondroplasia; administered as a daily subcutaneous injection, was approved by the European Medicines Agency in August 2021 for patients aged ≥2 years until closure of epiphyses. French Health Authorities granted early access to vosoritide treatment in France on 24 June 2021, which continued u...

During the COVID-19 pandemic, a significant increase in Central Precocious Puberty(CPP) has been observed worldwide. The reasons for this phenomenon are yet unclear. In order to evaluate if fear, stress and coping strategies used by children and parents when dealing with negative emotional situations and health issues might have acted as triggers for this phenomenon, we administered specific questionnaires to girls who had a diagnosis of CPP before and after the COVID-19 relat...
