Background: Although adequate hydration is recommended for healthy nutrition, the link between less water consumption and obesity is not exactly known. It was demonstrated that less hydrated adults had a higher body mass index (BMI). Data in children are rather limited. Our aim was to compare the hydration status between obese and non-obese children.Subjects and methods: Children aged between 7 and 18 years who had a BMI over 2 standard deviation score (...

Background: Obesity or excess weight gain in pregnancy period cause increased insulin secretion even if glucose screening test is normal. The growth promoting effect of insulin may release somatotropic hormones, such as IGF1,2 and its binding proteins are involved in the regulation of foetal growth.Objective and hypotheses: In this study, we determined the changes of intrauterine growth factors (IGF1,2, and IGFBP3) in pregnants gained over weight during ...

Background: Hyperinsulinaemic Hypoglycaemia (HH) is a rare genetic disease and the treatment of HH in cases with unresponsiveness to medical therapy is subtotal pancreatectomy. In a recent study, the authors showed that sirolimus could be an alternative treatment in these patients. We aimed to evaluate the effectiveness of sirolimus in a newborn with HH.Case: A 10 day-old neonate presented with hyperinsulinaemic hypoglycaemia (glucose: 26 mg/dl, insulin:...

Background: Premature adrenarche is defined as the development of axillary and/or pubic hair in association of the DHEA-S concentrations >108.4 nmol/l (40 μg/dl) before the age of eight in girls.Objective and hypotheses: This retrospective study aimed to investigate the clinical presentation, metabolic status, growth velocity and pubertal timing of girls with premature adrenarche.Method: Medical records of 117 patients wer...

Introduction: ‘Receptor tyrosine kinase-like orphan receptor 2 (ROR2)’ is a transmembrane protein tyrosine kinase encoded by the ROR2 gene. Pathogenic mutations in ROR2 are involved in two diseases: biallelic loss-of-function mutations in Robinow syndrome and monoallelic gain-of-function mutations in brachydactyly type B1. Recently, monoallelic loss-of-function mutations in ROR2 have been reported as a cause of isolated short stature. Here we repor...

Introduction: Autoimmune polyendocrinopathy, candidiasis and ectodermal dystrophy (APECED) is a rare hereditary disorder with autoimmun manifestations affecting both endocrine and non-endocrine tissues. It is caused by mutations in the autoimmune regulatory (AIRE) gene which is defined by the presence of two of the three major components: Chronic mucocutaneous candidiasis, autoimmune hypoparathyroidism and Addison’s disease. Clinical manifestations may be developed during...

Background: The prevalence of autoimmune thyroid disease is higher in children with type 1 diabetes mellitus (T1DM).Objective and hypotheses: The aim of this study is to compare the frequency of autoimmune thyroiditis in children with T1DM according to the presence of diabetes autoantibodies.Method: This study included 533 (49% female) children with T1DM based on hospital records from a single center. Frequency of glutamic acid dec...

Objective and hypotheses: To answer the question of whether the age of diabetes onset is shifting to younger ages and whether the rate of DKA at presentation has changed over the 15 years in children with T1DM.Method: Patients with T1DM from a single center for Pediatric Endocrinology and Diabetes in Turkey since 1999 were included. In a period of 15 years, 517 patients (249 females) were divided into three groups due to the year of diabetes diagnosed (g...

Background: P450 oxidoreductase (POR) deficiency is the newest form of congenital adrenal hyperplasia first described in 2004. POR is a protein that transfers electrons from NADPH to all 50 microsomal forms of cytochrome P450. Mutations that cause POR deficiency result in partial deficiency of the enzymes 21-hydroxylase and 17α-hydroxylase. Remarkable clinical features of the POR deficiency are genital ambiguity in both sexes, glucocorticoid deficiency and Antley-Bixler s...

Background: Endothelial dysfunction is thought to be a key event in the development of atherosclerosis. Demonstration of increased endoglin expression in atherosclerotic plaques suggested participation of endoglin in atherogenesis. Endoglin expression was also related to nitric oxide (NO) production in endothelium.Objective and hypotheses: Aim of the study was to evaluate the subclinical atherosclerosis in adolescents with type 1 diabetes mellitus (T1DM)...
