Background: Endothelial progenitor cells (EPCs) are involved in the regeneration of the endothelial lining following blood vessel injury. The reduction in the number of EPCs was postulated to be associated with the initiation and progression of cardiovascular disease.Objective and hypotheses: This study aimed at exploration of the number of EPCs in obese non-diabetic children and adolescents and their relation to the fasting lipid levels, fasting glucose...

Introduction: Congenital lipoid adrenal hyperplasia (lipoid CAH), is a rare subtypes of adrenal hyperplasia yet the most fatal form, which seriously disrupts adrenal and gonadal steroidogenesis by a defect in the conversion of cholesterol to pregnenolone. Affected patients show salt loss from impaired mineralocorticoid and glucocorticoid synthesis. The defect in lipoid CAH is mainly in the steroidogenic acute regulatory protein (StAR), which promotes entry of ...

Disorders of sex development (DSDs)represent a diverse group of clinical conditions which have a very wide phenotypic spectrum associated with a complicated molecular background.Such conditions are considered among the most common birth defects andare frequently associated with congenital abnormalities.Herein we present 62 patients with DSD associated with somatic anomalies. Patients were selected from clinical genetics dept., NRC. They underwent complet...

Introduction: Osteogenesis Imperfecta (OI) is a group of rare hereditary collagen disorders. Vertebral compression fractures and vertebral deformities are well-known complications of OI. Intravenous zoledronic acid is widely used to improve the bone mineral density in children with OI. This study aimed at assessment of the changes in vertebral compression and shape in children who received regular zoledronic acid infusions.Method...

Background: Paragangliomas are rare tumours that originate from neural crest cells. Diagnosing and managing patients with paragangliomas pose several challenges.Objective: We investigated whether MECP2 defects are associated with an idiopathic CPP phenotype with or without mild neurodevelopmental abnormalities.Clinical presentation: A 14-year-old female presented with cons...

Introduction: The prevalence of paediatric Type 2 diabetes (T2DM) is increasing, contributed by rising incidence of obesity worldwide. Paediatric T2DM is a progressive disease with increased risk of complications and morbidities. Despite recent research, many aspects such as its pathophysiology and optimal management remain unknown.Aim: To characterise the cohort of T2DM patients across 2 large tertiary paediatric diabet...

Disorders of sex development (DSD) have defined as congenital conditions in which the development of chromosomal, gonadal, or anatomical sex is atypical. Wilms tumor 1(WT1) gene mutations have been described in 46,XY patients with ambiguous genitalia or complete gonadal dysgenesis with or without Wilms tumor, nephropathy, gonadoblastoma and other defects e.g. cryptorchidism, hypospadias. Sex chromosome mosaicism is a major cause of DSD with a wide phenotypic variability. The p...

Ovotesticular disorder of sex development (OT-DSD) is a rare disorder of sexual differentiation characterized by the presence of both testicular and ovarian tissues in the gonads of the same individual. Patients usually present at birth with ambiguous genitalia, and the majority showed a 46,XX karyotype, with absence of the SRY sequence. In this study we reported on nine patients with OT-DSD, who were referred to the Human Genetics and endocrinology Clinics, division ...

Background: Sex chromosome DSD constitute an important category in the definition of DSD.Objective and hypotheses: The study included 379 patients comprising a wide spectrum of presenting features, associated with different arrays of chromosomal abnormalities aiming at. Studying the prevalence of Sex chromosomal abnormalities among DSD patients.Method: Patients were subjected to detailed clinical examination, pubertal staging, cyto...

Background: Ovotesticular disorder of sex development (OT- DSD) is a very rare disorder characterized by the presence of both ovarian and testicular tissue in the same individual. It has an approximate incidence of less than 1/20 000.The patients usually present with ambiguous genitalia and the majority show a 46,XX karyotype, with absence of the SRY sequence.Objective and hypotheses: The study reports the cytogenetic variability and gonadal histological...
