Premature Adrenarche and Pseudohypoparathyroidism – Mechanistically Linked or Coincidence?

Odone Jessica , Yadlapalli Kumar , Burren Christine

Aims: To describe a case of premature adrenarche with pseudohypoparathyroidism, an as yet unreported combination.Case: An otherwise well 8 year old girl presented to a Paediatric Endocrine Clinic with early pubic hair development suggestive of Premature Adrenarche. Blood tests revealed hypocalcaemia, elevated phosphate and highly elevated parathyroid hormone (PTH) level, giving a biochemical diagnosis of pseudohypoparathyroidism. She had normal stature (...

Novel p.Asn628Ser Heterozygous Mutation in FGFR1 is Associated with Hartsfield Syndrome and Tumoral Calcinosis

Prasad Rathi , Brewer Carole , Burren Christine

Background: Our patient, a male infant has bilateral cleft lip and palate, bilateral split hand and foot, semilobar holoprosencephaly and specific pituitary defects (cranial diabetes insipidus, gonadotrophin deficiency). He developed tumoral calcinosis at 16 months.Objective and hypotheses: Our patient’s phenotype is suggestive of Hartsfield syndrome. We hypothesise that he harbours a FGFR1 mutation given recently published findings associa...

Autosomal Dominant Growth Hormone Deficiency due to a Novel Mutation in the gh1 Gene

Ternand Christine , Gao Harry , Miller Bradley

Background: Familial growth hormone deficiency (GHD) with an autosomal dominant inheritance pattern (isolated GHD type II) due to multiple different mutations in the GH1 gene have been described.Objective and hypotheses: Describe the clinical characteristics and mutation analysis of affected individuals in a family with growth hormone deficiency inherited in an autosomal dominant pattern.Method: Medical record review.<p class="...

Encephalitis Associated with Autoimmune Thyroiditis: A Rare Cause of Encephalopathy In Children

Fudvoye Julie , Lebrethon Marie-Christine , Leroy Patricia , Seghaye Marie-Christine , Parent Anne-Simone

A ten year old girl was brought by the emergency mobile service for a persistent status epilepticus despite administration of Diazepam on site. She had presented headaches for the last three days and one episode of fever was suspected but not measured four days earlier. She had one episode of dizziness five days earlier.Persistent status epilepticus required invasive ventilation as well as deep sedation with Levetiracetam, Midazolam, ketamine, phenytoin,...

Mutations in MODY Genes: About Four Cases of Congenital Hyperinsulinism

Berthelon Karen , Rouleau Stephanie , Dupuis Clementine , Bouhours Natacha , Donzeau Aurelie , Cessans Christine , Bellanne Christine , Coutant Regis

Background: Congenital hyperinsulinism (HI) is the most common cause of persistent hypoglycemia in infants and children.Objective and hypotheses: Recently, mutations in genes usually involved in MODY 1 and 3 have been described in HI.Method: We present here six cases of hyperinsulinism associated with MODY1 (one case) and MODY3 (four cases) and one case of HI associated with MODY5 mutation.Results: Case 1...

Does X-Chromosome Gene Dosage Determine Growth and Phenotypic Features in Turner Syndrome with 45,X/46,XX Mosaicism on Standard Karyotyping? A Cross-Sectional Analysis of the French National Rare Disease Network Database

Fiot Elodie , Zenaty Delphine , Pick Paul , Boizeau Patricia , Haignere Jeremy , Dos Santos Sophie , Christin-Maitre Sophie , Carel Jean-Claude , Leger Juliane , Turner Syndrome Study Group French

Background: Turner Syndrome (TS) with a 45,X phenotype is generally more severe than TS with mosaicism, but the potential role of the degree of mosaicism in modulating TS phenotype has never been investigated. We assessed the impact of various degrees of 45,X/ 46,XX mosaicism on phenotypic features in a cohort of TS patients.Method: We analysed a cohort of TS with 45,X/ 46,XX mosaicism (percentage mosaicism from peripheral blood lymphocytes, known in <em...

Endocrine Challenges in Patients with Thalassemia

Haamberg Tanja Christa , Schneider Christine , Rossler Jochen , Fluck Christa E

Introduction: Beta-thalassaemia is caused by point mutations leading to decreased production of beta-globin, which results in defective red blood cells and ineffective erythropoiesis. Complications are microcytic hypochromic anaemia, extramedullary haematopoiesis and increased intestinal iron absorption due to compensation mechanisms. The resulting iron overload can be aggravated by recurrent blood transfusions necessary for treatment of anaemia and may cause several endocrine...

Evaluation of the Combination of Anti-androgen and Anti-estrogen Treatment in Classical Congenital Adrenal Hyperplasia in Boys: Retrospective Study of 11 Cases

Lefevre Christine , Weill Jacques , Mazoyer Harmony , Cartigny Maryse

Background: Final height (FH) is reduced in congenital adrenal hyperplasia (CAH), due both to overtreatment by hydrocortisone therapy and to advanced epiphyseal closure linked to hyperandrogenism by Hydrocortisone therapeutic insufficiency.Objective and hypotheses: To evaluate the efficacy and safety of the addition of an androgen receptor competitor and an aromatase inhibitor to reduced hydrocortisone doses.Method...

Practicalities of Bisphosphonate use in UK Paediatric Tertiary Centres

Price Victoria , Ramakrishnan Renuka , Burren Christine , Dharmaraj Poonam

Background: On reviewing practical aspects of intravenous bisphosphonate use in our tertiary Children’s Hospital, we noted disparity between departments who prescribed these drugs. This included issues pertinent to patient safety and hospital management, e.g. the need for overnight admission for the first infusion, blood tests and monitoring for adverse events (AEs). We therefore decided to survey the practices of other tertiary Paediatric Endocrinology Centres.<p cla...

Bartter Syndrome with Bone-Destroying Hyperparathyroidism: About Two Cases, Genetically Proved, with Long-Lasting Follow-Up

Novo Robert , Cartigny Maryse , Lefevre Christine , Weill Jacques

Background: Bartter syndrome represents a rare severe condition, autosomal recessive, corresponding to several genes, characterized by an illness of the renal ascending branch of the handle of Henle. Only 15 cases of BSHPT have been communicated, either in publications or orally, but none presented such severe bone manifestation as ours.Objective and hypotheses: To present bone features of two patients suffering from severe BHSPT, so as the therapeutic a...
