Bismuth Elise , Plat Helene , Chevenne Didier , Chantelot Christine Bellane , Carel Jean-Claude , Tubiana-Rufi Nadia

Background: A diagnosis of diabetes in children used to mean type 1 diabetes (T1D) and lifelong insulin therapy. However, over the last decades the spectrum of diabetes has widened and even if auto immunity remains the most prevalent etiology, confounding factors and overlap with other causes of diabetes types sometimes make a revision of the initial diagnosis necessary.Objective and hypotheses: To classify diabetes etiologies in youth with diabetes usin...

Background: Boys with delayed puberty represent one of the main cause for pediatric endocrine referrals. Although the majority of them have constitutional delay of growth and puberty (CDGP), it is important to identify isolated hypogonadotropic hypogonadism (IHH) for optimal management.Objective and hypotheses: The aim of the study was to evaluate the usefulness of inhibin B and AMH as biological markers for distinguishing between CDGP and IHH.<p cla...

Absence of Puberty and Estrogen Resistance by Estrogen Alpha Receptor Inactivation in Two Sisters: A Mutation for Variable Phenotypic Severity

Delcour Clémence , Khawaja Nahla , Mammeri Hedi , Drira Leila , Chevenne Didier , Ajlouni Kamel , De Roux Nicolas

Introduction: Estrogens play an essential role in reproduction and their peripheral action is mediated via nuclear alfa and beta receptors (ER) as well as membrane receptors. To date, only 3 females and 2 males from 3 families with a loss of function of ERa have been reported. The phenotype in these families was strongly suggestive of an estrogen resistance with an absence of a complete puberty, a delay in epiphyseal maturation with high estradiol levels and e...

Background: Neonates born from mothers with Graves’ disease are at risk to develop hyperthyroidism due to placental transmission of TSH-receptor antibodies. Neonatal hyperthyroidism should be effectively diagnosed and treated to prevent severe complications of this disease (cardiac symptoms, poor weight gain, severe neurological manifestations).Objectives: To describe the post-natal follow-up of neonates born from women with Graves’ disease.</p...

Subcutaneous Continuous Administration of Recombinant Human Luteinizing and Follicle-Stimulating Hormones is an Effective Treatment for Micropenis During the Mini-Puberty

Background: Early postnatal administration of recombinant human gonadotropins can be an effective way to mimic mini-puberty, and thus increase penile growth in infants with congenital hypogonadotropic hypogonadism (CHH). We report for the first time its efficacy on an infant with partial androgen insensitivity syndrome (PAIS).Objective and hypotheses: To evaluate the benefits of a continuous subcutaneous infusion of recombinant human gonadotropins (CSCI-...

Background: Puberty is reported to be impaired in children with Sickle cell Anemia (SCA). Studies about this topic are rare in Sub-Saharan regionObjective and hypotheses: Assessment of pubertal development of children with SCA compared to healthy children in Mother and Child Center, CHANTAL BIYA Foundation.Method: We matched a group of 64 children with SCA (26 males, 38 females) with 94 healthy controls aged of 8–17 years old....

Background and Objectives: Chronic administration of synthetic glucocorticoids affects 1% of the world population and is responsible for secondary adrenal insufficiency for 40% of the patients. In pediatrics, glucocorticoid-induced adrenal insufficiency (GI-AI) diagnosis is based on the Low Dose Synacthen Test (LD-SST). Screening for glucocorticoid-induced adrenal insufficiency implies medical and economical costs due to the necessity of an intravenous line an...
