Background: Congenital Hypopituitarism (CH) is a rare heterogeneous genetic disorder characterized by the deficiency of pituitary hormones. CH can be associated with extra pituitary phenotypes such as midline craniofacial malformations. To date, a minority of patients carry pathogenic variants in more than 30 genes, and thus more than 80% of cases remain unresolved.Objective: To identify de novo pathogenic variants in no...

De Novo Formation of Neutralizing IGF-I Antibodies During rhIGF-1 Treatment in a Girl with IGFALS Deficiency as Distinct Adverse Event Interfering with Growth Promotion

Mittnacht Janna , Breil Thomas , Choukair Daniela , Duffert Christin , Hwa Vivian , Rosenfeld Ron , Bettendorf Markus

Background: IGFALS deficiency is a rare cause of GH insensitivity (GHI). We report a German girl with short stature who was born as 2nd child at 40 weeks of gestation. Her Caucasian parents were unrelated and healthy (target height 168 cm, SDS 0.2). She was born appropriately sized for gestational age (49 cm, SDS -1.2; 2950 g, SDS-1.2). Height (104.8 cm; SDS -2.94) and height velocity (5.1 cm / year; SDS -1.67) were reduced at the age of 6 years.</p...

Pseudo-Precocious Puberty in Children Triggered by Incidental Transdermal Contamination with Topical Sex Steroids Through Parents

Yakovenko Vira , Choukair Daniela , Duffert Christin , Mittnacht Jana , Klose Daniela , Bettendorf Markus

Introduction: Pseudo-precocious puberty may be triggered by either endogenous or exogenous sex steroids. Accidental ingestion of contraceptives, anabolic steroids or life style products containing sex steroids as well as transdermal transmission of topical sex steroids may cause early onset of secondary sexual development.Objective: To report the clinical course of incidental contamination with topical sex steroids in ch...

Estrogen Insensitivity due to a Novel ESR1 Mutation in a Consanguineous Family from Algeria

Kherra Sakina , Ladjouze Asmahane , Bernard Valerie , Anane Tahar , Laraba Abdenour , Christin-Maitre Sophie

Background: Estrogen insensitivity syndrome is a form of functional estrogen deficiency which is caused by a defect in the estrogen receptor type α (ESR1). As a result of the receptor mutation, estrogens cannot be recognized and hence initiate their biological action on pubertal growth, skeletal maturation, and accrual of bone mass. A mutation in the gene encoding ESR1 has been described in only 2 cases (one man and one woman). We now describe the first family with ESR1 m...

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...

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="...

Prevalence of Overweight and Obesity in Children and Adolescents in Izmir, Western Turkey

Nalbantoglu Ozlem , Ozkan Behzat , Tunc Selma , Apa Hursit

Background: Although the highest prevelance rates of childhood obesity and overweihgt have been observed in developed countries, its prevelance is reported to be increasing in developing countries as well. Prevelance of obesity and overweight in different regions of Turkey ranges between 1.6–7.8 and 9.9–17.6 respectively.Objective and hypotheses: The purpose of this study was to investigate the prevelance of obesity and overweight among student...

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...
