Assessment of vitamin D status and vitamin D receptor polymorphism in Egyptian children with Type 1 diabetes.

Background: The endocrine system of vitamin D regulates about 3 % of the human genome. Vitamin D exerts its actions via a nuclear vitamin D receptor (VDR) which in turn regulates insulin secretion from the pancreas. VDR gene polymorphisms could have an impact on how autoimmune illnesses like Type 1 diabetes mellitus (T1DM) develop.

Hearing assessment in Egyptian children with chronic renal failure on regular hemodialysis and renal transplantation children.

Introduction: Hearing impairment is frequent in patients with end-stage renal disease (ESRD). We aimed to assess the prevalence of hearing impairment in children on regular hemodialysis and renal transplantation.

Materials And Methods: Transient-evoked otoacoustic emissions (TEOAEs) has been done for 80 children on regular hemodialysis and 40 with renal transplant.

Primary hyperoxaluria type 1 in children: Clinical classification, renal replacement therapy, and outcome in a single centre experience.

Primary hyperoxaluria type 1 (PH1) is a rare disease that is challenged by the overproduced oxalate and commonly presented with radiopaque renal stones or obstructive uropathy. This study aimed to report clinical presentations, renal replacement therapy (RRT), and outcome of PH1 in end stage kidney disease (ESKD) children. This is an observational cohort study.

Role of Matrix Metalloproteinase-9 in Neonatal Hypoxic-Ischemic Encephalopathy.

Background: Neonatal encephalopathy is a heterogeneous syndrome characterised by signs of central nervous system dysfunction in the newborn. Matrix metalloproteinase-9(MMP-9) increases the blood-brain barrier permeability, and their inhibitors can reduce its damage. MMP-9 has been implicated specifically in cerebral ischemia.
