Background: We report here the case of a 5-week-old male patient, referred to the hospital because of failure to thrive. An adrenal insufficiency was diagnosed and the genetic testing showed a mutation in the DAX1 gene leading to a premature stop codon.In addition to adrenal hypoplasia congenita, DAX1 mutation is known to be classically associated with hypogonadotrophic hypogonadism which is mostly characterized by absence of onset of puberty and inferti...

Background: Gestational exposure to endocrine disrupting chemicals (EDCs) can impact the control of sexual differentiation by altering the hormonal environment of the foetus. Prenatal exposure to BPA, for instance could lead to disorders of sexual development. At the interface between the mother and the foetus, the placenta plays a key role in foetal programming and responds to environmental stressors in a sex specific manner. Epigenetics has appeared to be a key mechanism for...

Background: A combination of GH and a GnRH agonist is sometimes used to improve adult height in children with a poor height prediction, only few studies support this.Study design: In this multicenter study, 24 short girls in early puberty, with a bone age below 12.0 years, an adult height prediction below 151.0 cm and normal body proportions were treated with GH (Zomacton) transjections 50 μg/kg per day and triptorelin (Decapeptyl) i.m. (3.75 mg/mon...
