Effect of Recombinant Growth Hormone Therapy on Retinal Nerve Fiber in Children with Idiopathic Growth Hormone Deficiency

Çinici Emine , Orbak Zerrin

Introduction: Growth hormone (hGH) and/or growth factors are thought to play a role in the pathogenesis of diabetic retinopathy. Increased treatment of human growth hormone (hGH) in children rise questions concerning the safety of GH replacement therapy on ophtalmic changes. Adverse effects of hGH treatment (pseudotumor cerebri, papilloedema, retinal changes mimicking diabetic retinopathy, neovascularization) have been reported in some papers. In this study, i...

A Cause of Severe Hypercalcaemia: Overdose or Hypersensitivity to Vitamin D?

Orbak Zerrin , Yesilcibik Remziye Seda , Unal Bahri

Background: Hypercalcaemia is caused by many different conditions. Vitamin D intoxication with severe hypercalcemia is rare in the neonatal and infancy period. Here we described a 4-month-old male with severe hypercalcemia secondary to taking oral 600 000 units of vitamin D. He was diagnosed vitamin D 24-hydroxylase gene (CYP24A1) mutation after evaluation.Case presentatıon: He was admitted to our hospital with high serum calcium level (23 mg/dl). S...

Liz Pacoricona Alfaro Dibia , Lemoine Perrine , Molinas Catherine , Diene Gwenaelle , Arnaud Catherine , Tauber Maithe

Introduction: Prader-Willi Syndrome (PWS) is a complex neurodevelopmental genetic disease comprising multiples cognitive, behavioural and endocrine abnormalities. This rare syndrome is one of the most common known reasons of syndromic obesity, a major cause of morbimortality among this population. In the last 20 years, substantial improvements have been made regarding the diagnosis, treatment and management of patients with PWS. Along those progresses, national policies were d...

Bisphosphonates Therapy in Girls with Rett Syndrome and Bone Fragility

Lambert Anne-Sophie , Rothenbuhler Anya , Charles Perrine , Celestin Elisabeth , Bahi-Buisson Nadia , Linglart Agnes

Background: Rett Syndrome (RS) is a disabling condition due to mutations in MECP2. Girls affected with RS are at risk of developing osteoporosis and fractures at a young age because of their lack of mobility and though a direct effect of MECP2 on bone mineralization. In these girls, bone fragility inflicts pain and may seriously impair the quality of life.Objective: To retrospectively assess the effect of pamidronate on fractures, bone mineral density (B...

The Relationship Between Leptin, Kisspeptin, Irisin, Myostatin and Omentin Levels and Fat Tissue at Puberty

Başak Polat Zeliha , Orbak Zerrin , Doneray Hakan , Ozturk Nurinnisa

Introduction: The hypothalamo-pituitary system is activated as puberty begins and GnRH release occurs as well as the synthesis of many hormones. These hormones cause changes on muscle development, body fat distribution. In this study, changes in miyostatin, irisin, kisspeptin, omentin and leptin levels and the relationship of these changes with physical properties and fat tissue were investigated.Material and Method: A t...

Can Different Diets (High Fat and High Fructose Diet) Affect Insulin Resistance, Tissue Advanced Glycation End Product Levels in Rats' Pancreas

Orbak Zerrin , Demirci Tuba , Ozturk Nurinnisa , Alaca Raziye

Introduction & Objectives: High consumption of processed foods rich in fat and sugar are associated with the increasing prevalence of metabolic disturbances like obesity, insülin resistance, dyslipidemia, type 2 diabetes mellitus. In the present study, we aimed to investigate the relationship between advanced glycation end products and metabolic disorders such as insulin resistance caused by high fructose and high-fat diet, and also examine histologic...

The Effect of Fibroblast Growth Factor 23 on Serum Phosphorus Level in Children with Diabetic Ketoacidosis

Doneray Hakan , Ozay Mustafa , Ozden Ayse , Ozturk Nurinnisa , Orbak Zerrin

Aim: The pathophysiology of developing hypophosphatemia in children with diabetic ketoacidosis (DKA) has not been sufficiently elucidated. Fibroblast Growth Factor 23 (FGF23) is a hormone that causes phosphate excretion from the kidneys. The increase of FGF23 in children with DKA may explain the pathophysiology of hypophosphatemia in these children. The aim of our study was to investigate the effect of serum FGF23 on serum phosphorus level in children with DKA...

Kaplan Nılgun , Orbak Zerrin , Doneray Hakan

Aim: To investigate the prevalence of hirsutism among adolescents using the modified Ferriman-Gallway (FG) Scale and to determine etiological factors in childen with hirsutism.Materials and methods: The study was in 2380 female adolescents aged 12–18 years. The modified FG score was used in the diagnosis and monitoring of hirsutism. Scores of 8 or above were regarded as hirsutism. Two hundred thirty-three volunteers determined as having hirsutism we...

The Postnatal Effect of Serum Vitamin D Binding Protein on Serum Vitamin D Level

Doneray Hakan , Yesilcibik Remziye Seda , Laloglu Esra , Orbak Zerrin

Background: It is not an uncommon situation that newborns have normal serum Ca, P, Mg, ALP, and PTH levels despite low vitamin D. Serum vitamin D binding protein (VDBG) may play a role for this situation. However, there is no any study investigated the relationship between serum vitamin D and VDBP in postnatal period.Objective and hypotheses: The aim of this study is to examine the relationship between serum vitamin D level and VDBP in neonates who have ...

Orbak Zerrin , Cayir Atilla , Doneray Hakan , Oral Akgun , Gursan Nesrin

Background: Thyroid nodules are rare in children compared to adults. Although most thyroid nodules are benign, the risk of malignancy is greater in pediatric patients.Case: We described a 10-year-old boy who presented with a right sided thyroid nodule that was 12×8 mm. He had not cervical lymphadenopathy. His fine needle aspiration biopsy cytology was benign. It was subsequently diagnosed as a Hurthle cell adenoma after thyroidectomy. In histopathol...
