Abnormal DNA methylation contributes to tumor progression and is emerging as a prognostic marker in several types of cancers. To investigate whether DNA methylation is associated with pediatric adrenocortical tumor (pACT) presentation and patient prognosis, we analyzed the methylation profile of 57 tumors (MethylationEPIC BeadChip Array-Illumina) and patients’ clinicopathological features and outcome. The study comprehended 40 girls and 17 boys, with median age at diagnos...

Background: It is well known that growth hormone (GH) brings about several effects, involving bone, body composition, lipids and glucose homeostasis. However, the complex interplay between these parameters is rather poorly studied in children with childhood-onset-GH deficiency (CO-GHD).Objective and hypotheses: To investigate lipids, adipokines (leptin- adiponectin- resistin) and glucose homeostasis and their relationship with bone and body composition i...

Background: Patients with disorders of sex development (DSD) require multidisciplinary team management for etiology identification and gender assignment. Identification of mullerian structures is an important part of the evaluation process. Ultrasonography remains the first-line imaging modality to delineate mullerian structures; while the importance of magnetic resonance imaging (MRI) is insufficiently studied.Objective and hypotheses: To evaluate the d...

Background: Diabetes is the third commonest chronic disease of childhood. When a child or an adolescent is diagnosed with type 1 diabetes (T1D), adaptation to a new life is usually a challenge for the whole family. There are specific challenges posed by T1D on the affected children, and their families, at different developmental age groups. The correlation between HbA1c and age specific psychological challenges, to our knowledge, has not been previously explored in the Middle ...

Background: Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder in which more than 90% of CAH cases are caused by mutations of the 21-hydroxylase (CYP21A2) gene.Objective and hypotheses: To determine the mutational spectrum in Egyptian CAH patients attending Diabetes Endocrine and Metabolism Pediatric Unit (DEMPU) including family members of CAH patients.Method: The use of reverse hybridization assay for the mol...

Background: Children with congenital adrenal hyperplasia (CAH) need chronic glucocorticoid therapy, both to replace congenital deficit in cortisol synthesis and to suppress the overproduction of androgens by the adrenal cortex. High doses of glucocorticoid taken chronically might affect bone metabolism and lead to alterations of bone mass in this condition. In particular, they could increase bone resorption rate. Bone mineral density (BMD) by energy X-ray abso...

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...

Background: Chronic kidney disease (CKD) was defined by structural or functional renal abnormalities, or an estimated glomerular filtration rate (GFR) of less than 60 mL/min per 1.73 m2. A child with CKD may develop many complications such as: anemia, poor growth and nutrition, bone and mineral disorders, cardiovascular complications, and complications of hemodialysis, and peritoneal dialysis.Aim: Assessment of severity ...

Background: Electrophysiological techniques allowed identification of sub-clinical pathological changes and early diagnosis of diabetic peripheral neuropathy (PN). Neopterin is a marker of inflammation and cellular immune response that is elevated in conditions of T-cell or macrophages activation. Diabetic peripheral neuropathy (PN) is associated with inflammatory/immune processes and therefore, we hypothesized that neopterin could be used as a marker of neuropathy in type 1 d...

Background: Diabetic nephropathy (DN) is a major microvascular complica-tion of type 1 diabetes mellitus (T1DM). Homocysteine levels have been found elevated in T1DM patients with DN due to several causes, including dietary deficiencies of folic acid and B Vitamins. Hyperhomocysteinemia induces renal injury and is associated with increasing urinary albumin excretion in patients with diabetes. We therefore performed a randomized-controlled trial of oral supplem...
