RNAi as Tool to Study Molecular Mechanisms of Metabolic Adverse Reactions in Caenorhabditis Elegans

Hornle Manuela , Hellwig Isabelle , Hodgkinson Steve , Kaschka Wolfgang

Background: The introduction of second generation antipsychotic (SGA) drugs for the treatment of bipolar disorders has been associated with metabolic adverse reactions. Many studies cite significant weight gain as a common side effect, which is often attributed to dysfunction of glucose homeostasis and the development of dyslipidaemia. This in turn may trigger the early pathogenesis observed for example in type-2-diabetes. Factors controlling energy metabolism are largely cons...

Novel Homozygous Mutation in the Sodium/Iodide Symporter (NIS) Gene Highlight by Next Generation Sequencing (NGS) in a Patient with Congenital Hypothyroidism

Petit Isabelle Oliver , Gennero Isabelle , Savagner Frederique

Background: The ability to concentrate iodide actively is a characteristic feature of the thyroid gland. This function is mediated through the sodium iodine symporter (NIS), a glycoprotein located in thyrocytes’membrane. Iodide transport defect (ITD) by NIS defects can result in hypothyroidism with variable degree of goiter and low to absent radio iodide uptake. Mutations in SLC5A5 gene encoding NIS are reported to be a rare form of dyshormonogenetic congenital hypothyroi...

Contribution of Next Generation Sequencing Approach for Management of Congenital Hypothyroidism with Eutopic Thyroid Gland

Savagner Frederique , Gennero Isabelle , Edouard Thomas , Cartault Audrey , Tauber Maithe , Petit Isabelle Oliver

Background: Congenital hypothyroidism (CH) is referred to dyshormonogenesis for 15 to 30%. Homozygous mutations associated have been demonstrated in DUOX2, TPO, TG, SLC5A5 (NIS), SLC26A4 (Pendred), DUOXA2, and IYD (DEHAL1) genes.Objective and hypotheses: Previous studies focusing on one or few thyroid-specific genes have proved not to be comprehensive enough for understanding physiopathological mechanisms of HC with dyshormonogenesis. Emerging diagnostic...

Proton Therapy as a Promising Therapeutic Option for Children with Aggressive and Uncontrolled Pituitary Macro Adenoma: A Case Report

Petit Isabelle Oliver , Bertozzi Anne-Isabelle , Boetto Sergio , Sevely Annick , Tauber Maithe , Caron Philippe , Alapetite Claire

Background: Non functioning pituitary macro adenoma is rare during childhood. Therapeutic options are reduced to surgery and radiotherapy. Proton therapy is a particle therapy that uses a beam of protons to irradiate the tissue with the chief advantage that as a charged particle the dose is deposited over a narrow range and there is minimal exit dose.Objective and hypotheses: Proton therapy is largely used in France for paediatric craniopharyngiomas irra...

Congenital Hypothyroidism Incidence and Dysgenesis or Dyshormonogenesis Prevalence in a Large Infants Cohort from South of France

Petit Isabelle Oliver , Lobinet Emilie , Gennero Isabelle , Edouard Thomas , Cartault Audrey , Tauber Maithe

Background: Congenital hypothyroidism (CH) is the most frequent endocrine disease in infants with prevalence ratio in the range of 1:2000–1:4000 new-borns. The disorder can be permanent (CHP) or transient (CHT). CH can be classified into two main groups: Dysgenesis, which accounts classically for 80–85% of cases and dyshormonogenesis for remaining 15–20%. From the last decade, studies described a upward trend for CH prevalence and changes in groups’ proport...

Multinodular Goiter in Childhood: A Diagnostic Gateway for Screening DICER1 Syndrome

Petit Isabelle Oliver , Grunenwald Solange , Golmard Lisa , Savagner Frederique

Background: DICER1 is a member of the Ribonuclease III family that plays a crucial role in the biogenesis and the maturation of microRNAs. Pathogenic germline DICER1 variants cause a hereditary cancer predisposition syndrome with a variety of manifestations: in addition to first described pleuropulmonary blastoma (PPB) and ovarian sex cord-stromal tumours, individuals may also develop benign (multinodular goiter MNG, cystic nephroma\.) or malignant tumours as differen...

Severe Hyperthyroidism in an Infant Revealed a Familial Non-Autoimmune Hyperthyroidism with Novel Heterozygous Thyrotropin Receptor Gene Mutation

Petit Isabelle Oliver , Savagner Frederique , Edouard Thomas , Caron Philippe

Background: The familial non-autoimmune hyperthyroidism (FNAH) is a hereditary disease caused by dominant activating mutations of the TSH receptor (TSHR) gene and rare in the paediatric population.Case presentation: A 20-month girl was referred for tachycardia. In personal history, she was delivered at 35 weeks of gestation by caesarean for fœtal tachycardia; she had been hospitalised at 1 and 5 months for diarrhoea and tachycardia was noticed. Clin...

Adherence to Diabetic Ketoacidosis Management Protocol: a Paediatric Centre Experience

Cloutier Daphne , Barbe Joanie , Bouchard Isabelle , Gagne Julie , Bourdages Macha

Background: Paediatric diabetic ketoacidosis (DKA) management should be regulated by specific protocols. Following the Canadian Diabetes Association recommendations, our paediatric tertiary care hospital was provided with such a protocol in 2009.Objective and hypotheses: Assess the proportion of DKA episodes that are marked by non-adherence to our DKA management protocol (DKAp). We suspected a moderate non-adherence rate.Method: We...

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

Stoupa Athanasia , Samara-Boustani Dinane , Flechtner Isabelle , Pinto Graziella , Jourdon Isabelle , Laborde Kathleen , Chevenne Didier , Millischer-Bellaiche Anne-Elodie , Polak Michel , Beltrand Jacques

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-...

Risk of Long-Term Endocrine Sequelae in Survivors of Progressing Childhood Optic Pathway Glioma (OPG) Treated by Upfront Chemotherapy: Preliminary Analyses of 102 Subjects from the French Multicentric BB-SFOP Registry

Hippolyte Helene , De Carli Emilie , Pellier Isabelle , Delion Matthieu , Rakotonjanahary Josue , Rialland Xavier , Coutant Regis

For the brain tumor committee of SFCE (Société Française des Cancers de l’Enfant).Objective: Therapeutic approach favors chemotherapy as the first-line-treatment in progressing OPG. There are few data on long term endocrine outcomes of aggressive OPG treated by upfront chemotherapy. Our main objective was to describe the long-term endocrine sequelae in these patients and to identify potential early predictors of the endocrine involvem...
