Objective: AMH causes fetal paramesonephric duct regression and is involved in testicular development and function. Sertoli cell AMH remains high during childhood until puberty. The appendix testis (AT), a remnant of the paramesonephric duct, contains both androgen and estrogen receptors. AT androgen receptors have been reported to play a role in embryonic testicular descent. The AT is commonly resected during orchiopexy and abdominal surgery as possible torsion in the future ...

Background: Most reports on gonadotoxicity associated with chemotherapy of acute lymphoblastic leukemia (ALL) comes from studies in adults, and they are mainly focused on the sensitivity of testicular germ cells. Little attention has been placed on Sertoli cells in prepubertal patients, even though Sertoli cell function is essential for adult spermatogenesis.Objective: To evaluate Sertoli cell function in prepubertal boys who receive chemotherapy for ALL...

Background: Congenital hyperinsulinism (HI) is the most common cause of persistent hypoglycemia which needs a prompt diagnosis and relevant treatment to avoid brain damage. So far, mutations in 11 key genes are known to cause monogenic forms of HI.Objective and hypotheses: The aim of this study was to characterize the clinical and molecular features of Turkish congenital HI patients and analyze the genotype/phenotype correlations.M...

Background: Congenital hyperinsulinism (CHI) is a rare condition characterized by unregulated secretion of insulin from pancreatic islet β cells. The primary treatment goal is to obtain normoglycemia, since hypoglycemia in the neonatal period can have severe impact on cerebral development.Objective and hypotheses: To assess the cerebral function in children with CHI at follow up.Method: From an international cohort, 40 childre...

Background: Honey is known for its medicinal and health promoting properties. It contains phytochemicals with high phenolic and flavonoid content, which contribute to its high antioxidant activity. Recent studies performed in adult healthy subjects suggest that honey has a beneficial effect on plasma glucose and serum insulin concentrations compared with monosacharides and disaccharides from different sources.Objective/hypotheses: To compare the effects ...

Background: Deficiency of 11β-hydroxylase is the second most frequent type of congenital adrenal hyperplasia and more common in Turkey than other populations.Objective and hypotheses: The purpose of this study is to examine the spectrum of CYP11B1 gene mutations in Turkish population.Method: 17 patients from 13 families are included in this study. Diagnosis was based on virilisation and high levels of 11-deoxycortisol. 15 case...

Background: There are limited data available on the efficacy and safety of GH treatment in very young (<30 months) short children, born small for gestational age (SGA).Objectives: To determine the effect of 24 months of GH treatment on body height, BMI, and head growth as well as overall psychomotor development (using the Bayley Scale of Infant Development (BSID-II)) and demonstrate its safety in young (aged between 19 and 29 months) short SGA childr...

Objective: To evaluate musculoskeletal development using pQCT in children with coeliac disease (CD) on gluten free diet (GFD) compared with age and gender matched healthy controls.Method: Prospective cross sectional study. 38 children (18 males) with CD on GFD for a duration of 3.6 years (0.6, 12.5) and 38 age and sex matched healthy controls underwent pQCT at 4, 38 and 66% tibial sites. Bloods were collected in CD children only. Results reported as medi...

Background: The steroidogenic enzyme aromatase is encoded by the CYP19A1 gene. Aromatase activity is required for estrogen biosynthesis from androgen precursors in the ovary and several extragonadal tissues. The role of aromatase and thus estrogens for human biology is best illustrated by disease states, both deficiency and excess which might be caused by genetic disorders.Aim: A novel deletion-insertion mutation spanning from intron 10 to the 3...

Background: Emerging evidence suggests FTO polymorphisms are associated with obesity-related comorbidities including type 2 diabetes (T2DM), hypertension and polycystic ovarian syndrome (PCOS). However association of FTO with other comorbidities such as obstructive sleep apnoea (OSA) in paediatric populations is less clear.Objective and hypotheses: To investigate the prevalence of obesity-related comorbidities according to FTO genotype in an obese paedia...
