Background: Obesity has increased drastically in the last few years. It’s well known the connection between intrauterine growth restriction (IUGR) and the development of metabolic syndrome based on the thrifty phenotype. Some studies have proposed that a poor intrauterine environment could lead to the development of chronic conditions later in life, and its believed leptin is involved in this process.Objective and hypotheses: Establish the mean of l...

Introduction: Le diabète de type 1 est l’endocrinopathie la plus fréquente chez l’enfant. Son incidence est en nette progression dans le monde. L’enfant diabétique nécessite une hygiène de vie adaptée et le suivi par une équipe pluridisciplinaire composée de pédiatre spécialiste en diabétologie, psychologue, diététicien, infirmier spécialisé.Objectif: Determiner les...

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: Cornelia de Lange (CdLS) syndrome (OMIM #122470) is a complex disease, characterized by distinctive facial features, failure to thrive, microcephaly, intrauterine growth retardation and anomalies in multiple organ systems. The complexity and severity of the endocrine commitment is variable. NIPBL, SMC1A, SMC3, RAD21 and HDAC8 genes, all involved in the cohesin pathway, have been identified to cause CdLS. There are few published studies on the endoc...

Background: The MAMLD1 gene (Xp28) is thought to cause disorder of sex development (DSD) in 46, XY patients, mostly presenting with hypospadias, and, recently, also gonadal dysgenesis. However, there is some controversy about the role of MAMLD1 in sex development because i) some MAMLD1 variants are also detected in normal individuals, ii) others are not present in all affected DSD individuals of the same family; iii) several MAMLD1 mutations...

Introduction: Subacute thyroiditis or De Quervain’s Thyroiditis is a self-limited inflammatory thyroid disease that is considered to be caused by a viral infection. Its incidence during the first decade of life is extremely rare. During the acute phase of the disease which lasts 2 to 6 weeks, the inflammatory process results in a temporary release of thyroid hormone with biochemical hyperthyroidism with or without symptoms. This phase is followed by a period with failing ...

Introduction and Aims: Autosomal dominant hypocalcemia or type V Bartter syndrome is characterized by hypocalcemia, low parathyroid hormone (PTH), and calciuria, which marks its prognosis due to the risk of nephrocalcinosis. It is caused by activating mutations in the calcium-sensing receptor (CASR) gene (3q21.1), which is expressed in the parathyroid and renal tubules, causing salt and potassium loss, due to the inhibition of the ROMK and NKCC2 channels. We s...

Background: Marfan syndrome is an autosomal dominant genetic disorder with skeletal, cardiac, and ocular involvement. Mutations in the fibrillin-1 gene on chromosome 15 are responsible for the development of the syndrome.Objective: To present one case of neonatal Marfan syndrome.Case: The patient was a 1-day-old female neonate who was born at 36 weeks gestation via normal delivery. Her body weight was 2900 g and height 48 cm. Ultra...

Background: Genetic defects in NKX2.1 (chromosome 14q13) are associated with hypothyroidism, choreo-athetotic movements and respiratory distress, known as the “Brain-Lung-Thyroid syndrome”.Objective and hypotheses: To identify the genetic basis of a disorder compatible with the “NKX2.1 syndrome” and extra features outside the typical triad.Patients and methods: 10-year old girl with congenital ...

Background: Thyroid hormone resistance (THR) is a rare genetic disorder that may be caused by thyroid hormone (TH) cell transporter defects or metabolism defects, but most cases are caused by an inherited mutation in the TH receptor beta (THRB) gene. The reduced responsiveness of target tissues to TH is characterized by elevated TH and a normal or elevated thyroid-stimulating hormone (TSH) level. Differentiating between THR and TSH-producing pituitary...
