Plasma steroid panel with liquid chromotography-mass spectrometry (LC/MS-MS) method: utilization in differential diagnosis of hyperandrogenism

Ucar Mert , Ata Aysun , Barutcuoğlu Burcu , Ak Guneş , Habif Sara , Parıldar Zuhal , Gokşen Damla , Darcan Şukran , Ege Samim Ozen ,

Introduction: The etiology of hyperandrogenism is diverse and diagnosis is based on history, clinical findings, reliable measurement of steroid hormones and genetic analyzes. In the electrochemiluminescence immunoassay (ECLIA) method, the presence of various endogenous compounds and the use of certain pharmaceutical agents may cause interference in results, on the other hand liquid chromatography-mass spectrometry (LC-MS/MS) method allows measurement of 17 adr...

Next-Generation Sequencing as a Rapid Molecular Diagnosis in Patients with 46,XY Disorder of Sex Development

Ozen Samim , Onay Huseyin , Atik Tahir , Solmaz Asli Ece , Goksen Damla , Ozkinay Ferda , Darcan Sukran

Background: 46,XY DSD occurs as a result of testicular developmental disorders, defect in androgen synthesis or action. Nowadays, the diagnosis of DSD is quite costly and it takes a considerable amount of time due to lengthy hormonal and genetic analysis.Objective and hypotheses: The use of targeted next-generation sequencing of all known genes associated with 46 XY DSD for a fast molecular genetic diagnosis in patients in whom underlying defect of DSD w...

Background: Screen (TV, tablet, smartphones, internet, video games, PC etc.) addiction is a growing problem in child health. The effect on insulin-glucose metabolism is not well known yet.Objective and hypotheses: To investigate the insulin resistance in screen addicted children.Method: We studied 108 children and adolescents aged 13.72±1.95 years (range 11–17 years). Participants were divided into three groups according ...

Management of Hypoparathyroidism: Follow-Up of 20 Patients

Darcan Sukran , Ozcan Nurhan , Ozen Samim , Goksen Damla

Background: Hypoparathyroidism is a rare disease characterized by inadequate parathyroid hormone (PTH), resulting in hypocalcemia and hyperphosphatemia. Hypoparathyroidism can be transient, inherited, or acquired, and is caused by inability to synthesize or secrete PTH, abnormal parathyroid gland development, destruction of parathyroid tissue, or peripheral resistance to PTH.Methods: Medical records from 20 children and adolescents diagnosed with hypopar...

Continuous Glucose Monitoring and Hypoglycemia Unawareness in Children and Adolescents with Type 1 Diabetes

Demir Gunay , Ozen Samim , Cetin Hafize , Darcan Sukran , Goksen Damla

Background: Seeking strict normoglycemia in type 1 diabetes mellitus increases the risk of hypoglycemia, exposing to hypoglycemia unawareness. Hypoglycemia unawareness (HU) is defined as the occurrence of hypoglycemic symptoms directly without autonomic symptoms. This study is designed to determine the incidence of HU in children and adolescents with continuous subcutaneous glucose monitoring system and to assess the effect of structured education to improve awareness.<p c...

A Novel MC4R Mutation Associated with Infancy-Onset Obesity

Goksen Damla , Onay Huseyin , Ozen Samim , Ozkinay Ferda , Darcan Sukran

Background: The melanocortin-4-receptor gene (MC4R) is a key regulator of energy homeostasis, food intake, and body weight which has intensively been analysed in molecular genetic obesity research. MC4R dysfunction in humans causes hyperphagia, impaired satiety and obesity. Most patients are heterozygotes, with some reports of homozygotes and compound heterozygotes.Objective and hypotheses: A 2-year-old boy with progressive weight gain from infa...

Is Plasma C-Type Natriuretic Peptide Level Available for Typing and Diagnosis of Skeletal Dysplasia Cases?

Kizilcan Cetin Sirmen , Goksen Damla , Ozen Samim , Alper Hudaver , Isık Esra , Onay Huseyin , Darcan Sukran

Introduction: Skeletal dysplasia is a heterogeneous group of disease, leading to abnormal enchondral ossification and typing of the disease is quite complex. C-type natriuretic peptide (CNP), one of the members of the natriuretic peptide family, has been implicated to play a role in bone development. CNP levels were high in some types of the skeletal dysplasia.Objective: The aim of this study is to evaluate the possibility of using CNP, as a marker for s...

The Effect of Polychlorinobiphenyls on Premature Puberty in Girls

Guven Raziye Burcu , Ozen Samim , Gokşen Damla , Korkmaz Ozlem , Darcan Şukran

Introduction: Studies show that onset of puberty in girls is occurring at increasingly younger ages. Environmental endocrine disruptors are implicated in the etiology of early puberty. Polychlorobiphenyls (PCBs) are one of the endocrine disruptor with proven estrogenic effects.Aim: To investigate the effect of PCBs on premature puberty in girls.Materials-Methods: The study group was selected from girls aged 2–8 years with a di...
