Identification of A Novel Homozygous Mutation in BBS10 in Five Children With Bardet-Biedl Syndrome

Yilmaz Gulay Can , Keskin Ece , Sobu Elif

Bardet-Biedl syndrome (BBS) is a rare and multisystemic disorder characterized by rod-cone dystrophy, post-axial polydactyly, learning difficulties, renal abnormalities, obesity and hypogonadism. The disorder is genetically heterogeneous. To date, 21 genes present on different chromosomes have been mapped. The most common genes are BBS1 (locus 11q13) and BBS10 (locus 12q21.2). We aimed to report two family with five affected children with typical clinical features of Bardet-Bi...

An Interesting Etiology in Childhood Central Diabetes Insipidus HIBERNOMA

Ergur Ayca Torel , Aslan Ayla , Canhilal Ece

Introduction: Central Diabetes Insipitus (CDI) results from the inability to secrete ADH secreted by the neurohypophysis system to control water-electrolyte metabolism. In the etiology of CDI many congenital and acquired CNS tumors, infiltrative diseases,infections, autoimmune events, head trauma and idiopathic can be responsible. In this article, a child case with CDI due to intracranial occurence which is very rare in etiology is presented and the approach and follow up are ...

Efficacy and Safety of Oral Alendronate Treatment in Children and Adolescents with Osteoporosis

Buyukgebiz Atilla , Bober Ece , Abaci Ayhan

Background: Osteoporosis is very rare in childhood and main reasons are growth retardation, immobilisation, calcium and vitamin D deficiency, long term steroid therapy. There is no concensus about the treatment of children and adolescents with osteoporosis. Biphosphonates have been important in the treatment of osteoporosis.Objective and hypotheses: To evaluate the efficacy and safety of oral alendronate on bone mineral density (BMD) in children and adol...

Clinical and Genetic Analysis of Five Patients with Vitamin D-Dependent Rickets Type 1A

Hacıhamdioglu Bulent , Ozgurhan Gamze , Karakaya Zeynep , Keskin Ece

The CYP27B1 gene encodes 25-hydroxyvitamin D-1α-hydroxylase. Mutations of this gene cause vitamin D-dependent rickets type 1A (VDDR-IA, OMIM 264700), which is a rare autosomal recessive disorder. Herein we report five patients with 1α-hydroxylase deficiencies. We studied six patients from three families who diagnosed as 1α-hydroxylase deficiency clinically. All patients had hypocalcemia, hypophosphatemia, hyperphosphatasemia, elevated serum PTH, normal or high v...

Retrospective Evaluation of the Efficiency of Metformin Therapy in Obese Children with Insulin Resistance

Cicek Gizem , Abaci Ayhan , Tuhan Hale , Demir Korcan , Bober Ece

Background: Prevalence of obesity has been rising throughout the world. Dyslipidemia, hypertension, insulin resistance, and type 2 diabetes mellitus (DMT2) (metabolic syndrome) are frequently observed serious complications of obesity. The primary approach in the treatment of metabolic syndrome is improving insulin resistance. Metformin is considered as an option for treatment in children with insulin resistance. During the last decade, numerous studies have been published demo...

Leptin Levels in Boys with Pubertal Gynecomastia

Buyukgebiz Atilla , Dundar Bumin , Dundar Nihal , Bober Ece

Background: It has been reported that there is a relationship between circulating leptin and sex steroid hormones and leptin is able to stimulate estrogen secretion by increasing aromatase activity in adipose stromal cells and breast tissue. Leptin receptors have been also shown in mammary epitheleal cells and it has been suggested that leptin is involved in the control of the proliferation of both normal and malignant breast cells.Objective and hypothes...

The Significance of GnRH Stimulation Test, Leptin, and Pelvic Ultrasound Findings for Differentiating Idiopathic Central Precocious Puberty from Premature Telarche

Ersoy Betul , Yazici Pinar , Onur Ece , Ozkol Mine

Background: We aimed to investigate the differences of serum leptin, gonadotropin hormones levels on GnRH stimulation test, and pelvic ultrasound (US) findings between girls with idiopathic central precocious puberty (ICPP) and premature telarche (PT). Additionally, we aimed to determine correlations between leptin and other parameters.Method: Thirty-nine girls who had the breast budding before the age of 8 years and 19 healthy age-matched pre-pubertal g...

Acar Sezer , Paketci Ahu , Kume Tuncay , Demir Korcan , Calan Ozlem Gursoy , Bober Ece , Abacı Ayhan

Introduction: Galanin is a neuropeptide involved in the regulation of food intake and glucose homeostasis. The objective of this study was to assess the relation of serum galanin levels with anthropometric and metabolic parameters in obese and healthy children.Material and methods: This cross-sectional study consisted of 38 obese children (mean age, 11.9±3.0 years) and 30 healthy children (mean age, 11.4±2.0 years). Clinical and biochemical [gl...
