Background/Aim: X-linked hypophosphatemia (XLH) is a rare disease caused by mutations in PHEX, leading to elevated FGF23 levels, hypophosphatemia and chronic renal phosphate wasting. Burosumab is a monoclonal antibody against anti-FGF23, which has been recently approved for treatment of XLH. Beyond clinical trials, little is known about its efficacy/safety in clinical practice which is the aim of study.Patients/Methods: ...

Ovarian steroid cell tumors (OSCT) are rare sex cord stromal tumors of the ovary and comprise <0.1% of all ovarian tumors. We herein report a case of an OSCT in a 9 year old girl patient who presented with central puberty preocious unresponsive to gonadotrophine relasing hormon analog (GnRH) therapy. A 9 year old girl presented with breast development noticed 4 months ago and menarche 3 months ago. Her height was 141,5 cm (+1,3 SDS), body weight was 35.4 kg (+0.9 SDS) and...

Development of Severe Obesity in a Children with a Brainstem Tumor

Pihoker Catherine , Roth Christian

The homeostatic control of energy balance is tightly regulated. Appetite and energy expenditure regulation involves neurons in the hypothalamus as well as other brain regions, including the limbic system, amygdala and the brainstem. Hypothalamic obesity is a well-recognized consequence of lesions such as craniopharyngiomas and other tumors in the hypothalamic region. Less known is obesity related to tumors in other brain regions. The child presented at 14 years of age with fai...

Single centre experience of Hydrocortisone Granules (Alkindi) in children under 6 years of age with Adrenal Insufficiency

Snow Claire , Owen Catherine ,

Introduction: Children with Adrenal insufficiency (AI) are usually managed with glucocorticoid replacement as hydrocortisone. Treatment options in younger patients include administering an aliquot of 10mg hydrocortisone tablets dissolved in water. However, this is time consuming and may be inaccurate. We describe our experience of using Alkindi (www.diurnal.co.uk), the first hydrocortisone preparation licensed for children with AI.<stron...

Thyroid Function and Autoimmunity and Their Relation to Weight Status in Healthy Children and Adolescents

Garcia-Garcia Emilio , Galera-Martinez Rafael , Garcia-Escobar Iciar , Oliva-Perez Patricia , Gomez-Llorente Jose L. , Momblan Jeronimo , Vazquez-Lopez Maria A. , Perales Antonio Bonillo

Background: The interrelationships between body weight and thyroid status are complex. Serum TSH is typically increased in obese compared with lean individuals. Several mechanisms leading to hyperthyrotropinemia have been hypothesized.Objective and hypotheses: To compare thyroid function and autoimmunity in normal, overweight and obese healthy children and adolescents in our population. To analyse any metabolic risk factor related to hyperthyrotropinemia...

A Novel Entity Characterised by GH Deficiency and Central Precocious Puberty in Two Siblings and their Father, in the Absence of Central Nervous System Defect

Voutetakis Antonis , Chiotis Dimitris , Dracopoulou-Vabouli Maria , Magiakou Alexandra-Maria , Chrousos Georgia , Chrousos George , Dacou-Voutetakis Catherine

Background: The association of GH deficiency (GHD) with central precocious puberty (CPP) has been reported in individuals with central nervous system (CNS) abnormalities, congenital or acquired. Co-existence of GHD and CPP has been rarely reported, always as an isolated, sporadic disorder.Objective and hypotheses: To present the familial occurrence of combined GHD and CPP.Method: GH was measured post L DOPA, glucagon and GHRH and g...

PTEN Hamartoma Tumor Syndrome (Overlap of Cowden syndrome and the Bannayan-Riley-Ruvalcaba Syndrome): Case Report

Manyas Hayrullah , Çatli Gönül , Eroglu Filibeli Berna , Ayranci Ilkay , Özdemir Taha Resid , Dündar Bumin Nuri

Introduction: PTEN Hamartoma Tumor Syndrome (PHTS) is a rare disease with dominant inheritance characterized by benign (hamartoma) and malignant tumors (breast, endometrium, thyroid). Mutations in the tumor suppressor gene phosphatase and tensin homologue (PTEN) gene are responsible for the etiology.Objective: In this case report, we present an 11-year-old male who was being monitored due to follicular thyroid cancer, an...

MKRN3 Gene Mutation in a Case of Familial Central Precocious Puberty

Eroğlu Filibeli Berna , Ayranci İlkay , Manyas Hayrullah , Kirbiyik Özgür , Dündar Bumin , Çatli Gönül

Introduction: Gain-of-function mutations in KISS1 and KISS1R genes and loss-of-function mutations in the gene encoding the makorin RING-finger protein 3 (MKRN3) expressed only in the paternal allele are the most common genetic reasons of familial central precocious puberty (CPP).Aim: We report a case of familial CPP and a pathogen variant in the MKRN3 gene.<stron...

Arthrogryposis Multiplex Congenita Type II and Panhypopituitarism

Bideci Aysun , Doğer Esra , Kılınc Uğurlu Aylin , Demet Akbaş Emine , Camurdan Orhun , Cinaz Peyami

Aim: Arthrogryposis Multiplex Congenita type II is an autosomal dominant disease, characterized by multiple congenital contractures in the limbs without a primary neurological deficit. The most frequently observed clinical features are triangular face, palpebral fissures facing downwards, clarity in nasolabial folds, small mouth, high palate, adherent ear lobes, short stature, camptodactyly, ulnar deviations in the fingers, vertical talus and/or talipes equinovarus.<p clas...

Triac Treatment Response to Thyroid Hormone Resistantance

Cinaz Peyami , Uğurlu Aylin Kılınc , Doğer Esra , Akbaş Emine Demet , Bideci Aysun , Camurdan Orhun

Aim: Resistance to thyroid hormone (RTH) is a disease characterized by decreased sensitivity to thyroid hormone in the peripheral tissues such as cell membrane, metabolism, or nuclear receptor. In THRB gene mutation induced RTH, the effect of T3 on TRβ mutant receptors in the liver and the pituitary decreased, on TRα receptors located in the brain and heart increased. Triac’s activity is similar to T3.Case: A 1-month-old girl patient was a...
