Background: RASopathies are a group of diseases with common clinical features that occur as a result of pathogenic variants in genes encoding components of the RAS/MAPK pathway. The aim of this study was to evaluate the clinical and molecular features of RASopathy cases in our pediatric endocrinology unit.Subjects and Methods: The clinical and molecular data of 42 patients (18 girls) from 39 families were evaluated, retr...

Introduction: 17α-hydroxylase deficiency (17OHD) is a rare form of congenital adrenal insufficiency characterized with decreased cortisol and sex steroid biosynthesis, overproduction of ACTH, and increased mineralocorticoids. The overproduction of corticosterone hinders the symptoms of glucocorticoid deficiency and causes sodium retention, hypertension, and hypokalemia in severe cases. Affected 46,XX and 46,XY individuals are phenotypically female in the...

Introduction and Aim: In this study, we aimed to investigate the admission characteristics, the ratio of permanent/transient hypothyroidism, and the predictors of permanent or transient hypothyroidism at initial evaluation in newborns admitted in 2013 and 2014 from neonatal TSH screening program.Method and Results: During two years period, 985 babies were admitted to our clinic with screening results for evaluation, and ...

Context: Clinical experience is limited regarding the efficacy of different depot Leuprolide acetate (dLA) treatment protocols in girls with central precocious puberty (CPP).Aim: To compare the 3.75 mg/4 weeks versus 11.25 mg/12 weeks ıntramuscular injection of dLA in suppressing gonadotropins and pubertal development.Subjects and Methods: In a prospective study, 92 girls wit...

Context: Intravenous Gonadotropin-Releasing-Hormone (GnRH) stimulation test has a central role in evaluating gonadotropic activation in the diagnosis and monitorization of the treatment in patients with central precocious puberty (CPP). However, this test is invasive, laborious, costly and availability of GnRH preparation is limited in some countries.Objective: To evaluate the utility of the LH level measured 40-minutes ...

Background: Myo-inositol(MI)is a polyol involved in intracellular signaling pathways of insulin and MI has been used orally for therapeutic purposes in girls and adult women with polycystic ovary syndrome(PCOS)with variable success. As yet, serum MI levels have not been assessed in girls with PCOS.Aim: Our primary goal was to compare serum MI levels in girls with PCOS with those in healthy peers. Secondary goal was to in...

Background: Osteogenesis imperfecta (OI) is characterized by low bone mass and bone fragility mainly due to COL1A1/COL1A2 gene defects. However, >17 genes have been identified in the pathogenesis of OI. Here, we aim to characterize genotypic spectrum of our OI cohort.Methods: Forty-nine OI patients (28 males) from 38 different families (13 consanguineous/9 multiplex) were screened with the next-gene...

The weight of birth affects the weight status and fat distribution in the later period of life. It is suggested that both low and high birth weight pose a risk for cardiometabolic diseases. In this study, the effects of birth weight on body fat mass and body fat distribution parameters during childhood and adolescence period were evaluated.Method: In this cross-sectional study, 4581 children ages between 6-17 years at primary and secon...

Background: No large study comparing efficiency of prednisolone, alendronate and pamidronate has been conducted so far in children with hypercalcemia due to vitamin D intoxication.Objective and hypotheses: To perform a multicentre, retrospective study assessing clinical characteristics and treatment results.Method: A standard questionnaire was uploaded to an online national database system (www.favorsci.org) to collect data of chil...

Objective: To describe clinical, laboratory and genetic characteristics of 42 short children from 34 consanguineous Turkish families.Design: Descriptive case series.Methods: After collecting clinical information, DNA samples were analysed in three European laboratories. In 18 children (12 families) suspected of a genetic defect in the growth hormone (GH)-insulin-like growth factor ...
