Background: Vitamin D deficiency (VDD) is common in the general pediatric population of the world. Some studies reported that low vitamin D levels with an increased risk of diabetes.Objective and hypotheses: VDD can be more common in children with type 1A diabetes (DM1A) than those with type 1B diabetes (DM1B). To evaluate 25OHD levels in children with newly diagnosed DM1A and DM1B patients and investigate any relation with clinical and laboratory data a...

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...

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...

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...

Introduction & Objectives: Fat and fructose-rich nutrition bring many metabolic diseases, especially obesity and diabetes. Recent years, more scientific interest in how can diet effect on brain function has emerged. We aimed to investigate the effect of high fructose and high-fat diet on the brain, and whether the presence of relationship with advanced glycation end products histologically, in rat model.Materials & Method...

Background: Androgens play a pivotal role in non-reproductive tissues, such as the kidney, heart, and liver, as well as the pancreas. Since the androgen receptor is expressed in pancreas and liver cells, this raises the possibility that excess testosterone results in insulin hypersecretion, and in fetuin-A, a protein produced in the liver. However, whether fetuin-A and insulin levels are affected by androgens in classic congenital adrenal hyperplasia (CAH) due...

Introduction: High doses of biotin are reported to cause incorrect results in various immunoassays in some patients. However, there is no systematic study regarding biotin interference in childhood.Aim: To assess thyroid function with different methods in subjects with biotinidase deficiency, to determine the factors causing interference, and to investigate the efficiency of the methods for overcoming interference.Method: The study...

Background: Osteogenesis imperfecta type XVII (OI17) (MIM#182120) have been described recently due to mutation in secreted protein, acidic, cysteine-rich (SPARC) gene located on 5q33.1.Objective and hypotheses: Here we report a novel mutation in SPARC causing OI17.Case: Two siblings presented to our clinic at the age of 10.3 and 0.5 years old. Parents were consanguineous. The older one was born with birth weight &...

Background: Osteogenesis imperfecta (OI) is a heterogeneous group of brittle bone disease mostly caused by quantative or qualitative defects in type I collagen. In most populations, more than 90% of the patients with OI have dominant mutations in COL1A1 or COL1A2 genes (AD-OI). Less than 10% of the cases have recessive inheritance (AR-OI). Currently 12 genes have been identified as a cause of AR-OI.Objective and hypotheses: We assumed h...

Objective: Fetuin-A has many different functions due to its ability to bind to different toll-like receptors in different tissues. Working in different groups will contribute to our understanding of the pathophysiology of Fetuin-A. In this study, we aimed to evaluate Fetuin-A levels in obese adolescents and the relationship between Fetuin-A and anthropometric data, insulin levels and high sensitivity CRP(HSCRP). Material and Meth...
