Vuralli Dogus , Yildiz Yilmaz , Serap Sivri H. , Alikasifoglu Ayfer

Introduction: Congenital disorder of glycosylation type-1a is a multi-system disease involving neurological, gastrointestinal, ophthalmologic, cardiac or endocrine systems. In addition to hypothyroidism and hypergonadotropic hypogonadism, rare occurrences of hyperinsulinemic hypoglycemia in CDG patients have been reported. In the present report, we describe a patient diagnosed with CDG type-1a accompanied by hyperinsulinemic hypoglycemia, and whose responsive to diazoxide....

Gender-Related Differences in Etiological Distribution of Organic Causes of Central Precocious Puberty

Vuralli Dogus , Ozon Alev , Gonc Nazli , Kandemir Nurgun , Alikasifoglu Ayfer

Introduction: Organic lesion underlying central precocious puberty (CPP) is common in boys, and rare in girls. We aimed to compare the etiological distribution of organic causes according to gender, and define the clinical-laboratory characteristics that predict an organic cause to CPP.Subject and methods: Medical records of 260 girls and 120 boys with CPP were reviewed retrospectively to analyze the clinical, laboratory characteristics, radiological fin...

Clinical and Laboratory Parameters Predicting a Requirement for Reevaluation of GH Status During GH Treatment

Vuralli Dogus , Gonc Nazli , Ozon Alev , Alikasifoglu Ayfer , Kandemir Nurgun

Background: Reevaluation of children diagnosed as GH deficiency (GHD) showed 25–75% of cases had normal GH responses in retests after cessation of therapy. Low reproducibility and high intra-individual variability of the tests are the important problems in diagnosis. Repeat evaluation during treatment may help detect cases with normal GH status earlier.Objective and hypotheses: We repeated stimulation tests following the first year of GH treatment t...

Improvement of Final Height in Idiopathic Central Precocious Puberty is Associated with Delay of Bone Maturation with GnRH Agonist Therapy Under the Age of 7 Years

Vuralli Dogus , Gonc E. Nazli , Ozon Z. Alev , Kandemir Nurgun , Alikasifoglu Ayfer

Background: GnRHa therapy is shown to be beneficial in increasing final height when started before 6 years of age in girls with idiopathic CPP(iCPP). However controversial data exist in improvement of final height whose pubertal signs appear after age of 6.Aim: To investigate effect of age of onset of GnRHa therapy on final height n girls with iCPP, and to evaluate factors affecting height gain.<st...

Spondyloocular Syndrome: Presentation of Two Siblings Diagnosed with The Rare Disease and The Results of Pamidronate Therapy

Vuralli Dogus , Simsek Kiper Pelin Ozlem , Utine Eda , Unsal Yagmur , Alikasifoglu Ayfer , Kandemir Nurgun

Spondyloocular syndrome (OMIM 605822) is an autosomal recessive disorder characterized by skeletal complaints (osteoporosis, platyspondyly, multiple bone fractures), hearing loss and ocular symptoms (cataracts, retinal detachment). XYLT2 gene (OMIM 608125) mutation encoding xylosyltransferase II enzyme which is responsible from the first step of proteoglycan assembly is responsible for the pathogenesis. Phenotypical variability is associated with varying genetic expre...

Long Term Effects of GnRH Agonist Therapy on BMI in Girls with Idiopathic Central Precocious Puberty

Vuralli Dogus , Ozon Z. Alev , Gonc E. Nazli , Alikasifoglu Ayfer , Kandemir Nurgun

Background: Studies investigating effects of GnRHa therapy on body weight (BW) and BMI in subjects with CPP are generally including short term effects.Aim: To investigate changes in BMI at the beginning, during and two years after completion of GnRHa therapy to determine influential factors in girls with idiopathic CPP.Methods: Data of 138 girls who completed GnRHa therapy for iCPP...

To Whom Should Central Nervous System Imaging be Performed in Girls with Central Precocious Puberty (CPP)?

Vuralli Dogus , Gonc E. Nazli , Alikasifoglu Ayfer , Kandemir Nurgun , Ozon Z. Alev

Background: Organic lesions are present in 5-10% of cases with CPP. Determinants of an increased risk for organic pathology underlying CPP in girls are debatable. CNS imaging is recommended for girls who have pubertal signs before 6 years of age. Although neurological findings may suggest organic pathology, other clinical features and hormonal variables have not been adequately examined.Aim: To analyze clinical&h...

What is the Best Parameter to Decide the Initial Dose of Depot Leuprolide Acetate in Girls with Idiopathic Central Precocious Puberty?

Vuralli Dogus , Alikasifoglu Ayfer , Iyigun Irem , Canoruc Dicle , Ozon Alev , Gonc Nazli , Kandemir Nurgun

Introduction: Formulations and doses of GnRH analogues used to treat idiopathic central precocious puberty (iCPP) may vary with clinician preference or local approvals. Aim of this study is to define factors that affect initial depot leuprolide acetate (LA) dose which suppress hypothalamo-pituitary-gonad (HPG) axis in girls with iCPP.Methods: A total of 220 girls receiving LA for iCPP were included. LA is started in the dose of 3.75 mg/28 days, and suppr...

The Frequency of Obstructive Sleep Apnea in Children with Hypothalamic and Exogenous Obesity

Iyigun Irem , Alikasifoglu Ayfer , Ozon Alev , Gonc Nazli , Hizal Mina , Eryilmaz Sanem , Kiper Nural , Ozcelik Ugur

Introduction: Hypothalamus is an important regulator of sleep onset, sleep maintenance and wakefulness as well as appetite control. Thus, hypothalamic damage can lead to both sleep dysregulation and severe morbid obesity. So, sleep apnea may be more prevalent and severe in obesity due to hypothalamic damage in comparison to exogenous obesity.Aim: We aim to compare frequency and severity of obstructive sleep apnea (OSA) in children with hypothalamic and e...
