Background: Hyperostosis-hyperphosphataemia syndrome (HHS) is a rare autosomal recessive metabolic disorder, characterized by recurrent painful swelling of long bones, periosteal new bone formation and cortical hyperostosis or intramedullary sclerosis, hyperphosphatemia and low intact fibroblast growth factor 23 (FGF23) protein levels. It is caused by mutations in two genes, N-acetylgalactosaminyltransferase 3 (GalNAc-transferase; GALNT3) and FGF23.<p class="abste...

Background: Biallelic QRSL1 mutations cause mitochondrial “combined oxidative phosphorylation deficiency-40” (COXPD40). COXPD40 has been reported invariably lethal in infancy. Adrenal insufficiency was weakly reported and investigated among seven previously reported patients with COXPD40.Objective: We report clinical, biochemical, molecular, and functional characteristics of a patient with adrenal in...

The stimulants that the mother is exposed during pregnancy may affect the baby in the future. Electromagnetic field exposure is an important external stimulus that we are subject to. In addition to the interaction of the earth and the sun with the magnetic field of man; nowadays the intensive use of electrical appliances, computers, mobile phones and internet, how electromagnetic field exposure may affect future generations will only occur in the continuation of our generation...

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: C1q/tumor necrosis factor-related proteins (CTRPs) are the recently recognized members of the adipokine family, secreted from adipose tissue. Some types of CTRPs, including CTRP-13, play an important role in energy metabolism in humans. Also, CTRP-13 was found as an anorexigenic factor in experimental studies.Objective: We aimed to investigate serum CTRP-13 levels in obese and healthy children, as well as the...

"Steroidogenic Factor-1" (SF-1); It is encoded by the NR5A1 gene in 9q 33.3 and regulates the transcription of genes involved in steroidogenesis. It is reported that 46 of the variants in this gene constitute 10-20% of XY sex development disorders (DSD). The patient admitted because of a swelling in the left groin at one month old. She was raised as female. Uterus was 12x2.5 mm in ultrasonography and the gonad in the inguinal region was evaluated as testis. She was P...

Aim: The study aimed to assess the development of early diabetic retinopathy (DR), one of the microvascular complications, in patients with isolated type 1 diabetes mellitus (DM) (group 1), type 1 DM with a diagnosis of autoimmune thyroiditis (AT) (group 2), and healthy controls (group 3), which were matched for age, sex, number, and body mass index for comparison.Methods: In this prospective and observational study, gro...

Introduction: Congenital Adrenal Hyperplasia (CAH) is a chronic disease that requires life-long hormonal replacement therapy. Growth of patients with CAH can be affected by this therapy or the hyperandrogenic effect of the disease. In this study, we aimed to assess the potential effect of CAH and its therapy on final height in Saudi affected patients.Methodology: This is a retrospective cohort study from two tertiary end...

Androgen insensitivity syndrome (AIS) is the largest single entity that leads to male under-masculinization. Although adequate serum concentrations of testosterone exclude a defect in testosterone biosynthesis, a low testosterone value at baseline does not always exclude PAIS. Anti-Müllerian hormone (AMH), also called Müllerian inhibiting substance or factor, is secreted in high amounts by the immature Sertoli cell; it is negatively regulated by testosterone.<p c...

Case presentation: We report a five -year-old girl who presented for evaluation of obesity, abdominal distension, vaginal bleeding for two days, and abdominal distention. There was no history of local trauma or vaginal discharge associated with the vaginal bleeding and no suspicion of abuse. There was no purpura or bleeding from other sites. Her HtSDS = -1.3 SD and BMI SDS = + 1.5 SD. A large abdominal mass was palpable. There was no hepatomegaly, splenomegaly or lymphadenopat...
