Background: Both The Endocrine Society and the World Professional Association for Transgender Health (WPATH) published guidelines for the treatment of children and adolescents with gender dysphoria (GD). The guidelines recommend the use of GnRH agonists in adolescence to suppress puberty, and the use of cross-sex hormones starting around age 16 for eligible patients. In actual practice, there is no consensus whether to use these early medical interventions. The aim of our stud...

Background: Virilization of young children after topical androgen use by their fathers through skin contact is well-known. The long-term consequences of such exposure at very young age are not well known.Objective and hypotheses: The aim is to report the occurrence of spermarche in a young boy and central precocious puberty in a young girl as late consequences of interpersonal transfer of testosterone gel.Method: Testosterone conta...

Background: IGF1 is essential for pre and postnatal growth. Mutations in IGF1 receptor (IGF1R) gene have been described in patients with intrauterine growth retardation and other anomalies.Objective and hypotheses: To study IGF1R gene in small for gestational age (SGA) patients with short stature and correlate the results with clinical presentation and response to rhGH treatment.Method: Longitudinal retrospective study of 69 SGA pa...

Background: In our center for adults with rare genetic syndromes, we see adolescents and young adults with overgrowth syndromes, among others. In our 'general endocrinology' outpatient clinic, we also see patients with overgrowth, but in these cases the overgrowth is due to excess of growth hormone (GH). Our clinical impression is that the differentiation between the two is often challenging. Therefore, we believe it is important to emphasize the dif...

Background: Congenital GH deficiency (GHD) can be isolated (IGHD) or combined with other pituitary hormone deficiencies (CPHD). The identification of mutations has clinical implications for the management of patients and genetic counseling1.Objective: To prospectively conduct a molecular-genetic analysis in genes associated with IGHD or CPHD.Method: Forty patients with IGHD (n=8) or CPHD (n=32) were stu...

La puberté précoce est définie comme le développement des caractéristiques sexuelles avant l'âge de 8 ans chez les filles et de 9,5 ans chez les garçons. L'objectif de notre étude était de calculer la prévalence de la puberté précoce en consultation spécialisée et de décrire le profil clinique, paraclinique, étiologique et de prise en charge ainsi que la qua...

Hyperinsulinemic hypoglycaemia (HH) is a common cause of severe and persistent hypoglycaemia during the neonatal period. Risk factors for neonatal transient hyperinsulinism are small-for-gestational age (SGA), perinatal asphyxia and maternal diabetes mellitus. This state of hyperinsulinism in SGA newborns could persist from weeks to years, resulting in an important comorbidity; its pathogenesis remains unknown.Objective: To describe the clinical-genetic ...

Background: Preterm newborns due to their immaturity, a higher incidence of mortality and increased susceptibility to iodine, are at risk of decreased thyroid function. Low levels of thyroid hormones during a critical period for the development of the central nervous system may negatively affect their psychomotor development. Screening for congenital hypothyroidism with capillary TSH is invalid for preterm babies and would require an specific thyroid function control.<p cl...

Introduction: Transgender people and the gender transition process requires a series of processes with psychosocial, legal and physical implications. In our community, with the establishment of the care plan for trans youth, reference units were created in 2015. We had an interest to analyze the different epidemiological variables and the type of care demand of this population cared for in our unit.Methodology: An observ...

Background: Congenital adrenal hyperplasia, one of the most frequent autosome recessive disorders, is caused by defects in steroidogenic enzymes involved in the cortisol biosynthesis. Approximately 95% of cases are caused by a deficiency of the 21-hydroxylase enzyme. Its deficiency leads to androgen excess, consequently, to virilization and rapid somatic growth with accelerated skeletal maturation. Mutations in CYP21A2 are responsible for different forms of 21-hydroxylase defi...
