Background: The N-acetyltransferase 2 (NAT2) A803G polymorphism leading to substitution of lysine to arginine at residue 268 and codifying for a cytosolic enzyme catalysing acetyl-CoA-dependent N- and O-acetylation reactions, has been associated with decreased insulin sensitivity in a large adult population with the A allele associated with insulin resistance (IR)-related traits.Objective and hypotheses: We screened for this polymorphism, for th...

Background: Phthalate exposure results in endocrine disruption by inhibiting steroidogenesis, inducing focal dysgenesis and disrupting germ cell development in the rat fetal testis. Whilst phthalate exposure does not reduce testosterone production by the human fetal testis, its effects on germ cells and induction of dysgenetic areas in the developing human testis are less well described.Objective and Hypotheses: To determine the effects of phthalate expo...

Introduction: Many potential factors can affect or be influenced by placental size. These include gestational age, maternal age, race, socioeconomic status, and gender of the baby.Aim: We investigated the possible association/s between placental weight on the one hand and birth weight, gestational age, maternal age, and gender of the baby in a large cohort of newborns (n = 80722)Me...

Background: Epidemiological studies have shown associations between placental weight (PW) and perinatal and postnatal linear growth and weight gain.Objectives: To report trimmed placental weight (PWT) and evaluate their association with birth weight (BWT), and gestational age (GA) in a large cohort of mother/ baby pairs in Qatar. (n= 80722).Methods: Retrospective data anal...

Introduction: Early and fast puberty (EFP) in girls, defined as pubertal onset at age 8-9 yr., with an accelerated course, may cause compromised final adult height (FAHt). Treatment with a gonadotropin-suppressive agent is still controversial because the improvement in FAHt is equivocal and there may be a risk of overweight.Aim of the study: We analyzed the data of 24 girls with EFP treated with GnRH analog (GnRH) since Tanner stage 2-3,...

Background: Childhood cancer survivors (CCS) are at risk for low bone mineral density (BMD).Objective: Aim of our study was to evaluate the prevalence of low BMD and it’s determinants in a single-center cohort of CCS.Method: One-hundred-eighty-five CCS (103M, 84F) diagnosed with liquid-LT-(n=48), solid-ST-(n=88) and brain tumor-BT-(n=51) at the age of 5.3±3.2 years underwent height, BMI (SDS), T...

Children with diabetes, and particularly those with obesity, have poor glycemic control. They are thus at higher risk of early microvascular complications. Renal tubulointerstitial markers are integral to evaluating diabetic nephropathy. Various biomarkers have been proposed, but their role in the obese pediatric population is uncertain. We investigated renal injury markers in children with diabetes, according to obesity, and determined their role as early predictors of diabet...

Background: Studies investigating effects of GnRHa therapy on body weight (BW) and BMI in subjects with CPP are generally including short term effects.Aim: To investigate changes in BMI at the beginning, during and two years after completion of GnRHa therapy to determine influential factors in girls with idiopathic CPP.Methods: Data of 138 girls who completed GnRHa therapy for iCPP...

Introduction: Early-onset severe obesity (before five years of age) without intellectual deficit, dysmorphisms, or malformations raises the hypothesis of monogenic obesity. The leptin receptor (Lepr) pathway is essential for food intake regulation, energy expenditure, and body weight. Mutations in leptin and the Lepr have been shown to cause early-onset severe obesity in mice and humans.Objective: To report the clinical ...

Background: 17-β-hydroxysteroid dehydrogenase 3 (17-β-HSD3) deficiency is a rare disorder of sex development due to impaired conversion of androstenedione to testosterone. Children with 46,XY karyotype often have female appearing external or ambiguous genitalia at birth. At the time of puberty, virilisation can occur. Therefore 46,XY patients with HSD17B3 gene defects should be raised as male.Objective and hypotheses: When a child with 46,XY ka...
