Introduction: Persistent Müllerian duct syndrome (PMDS) is a rare disorder of sex development (DSD) characterized by the persistence of Müllerian derivatives, the uterus and/or fallopian tubes, in otherwise normally virilized boys. PMDS is caused by mutations in the genes coding anti-Müllerian hormone (AMH, PMDS type 1) or the AMH receptor (AMHR2 gene, PMDS type 2) and it usually presents as undescended testes (cryptorchidism) or inguinal hernia...

Background: Several genetic defects (GHR, SHOX, GHSR, NPR2, IGFALS) have been reported in children classified as ISS. ISS children are GH sufficient and about one third of them show low IGF-I levels, suggesting some degree of GH insensitivity.Objective: To explore potential genetic defects in ISS children suspicious of GH insensitivity, selected by low IGF-I levels and low response to IGF generation test.<...

Background: We have recently reported the molecular diagnosis of two patients with severe growth failure associated with a spectrum of early-onset autoimmune disease and immunodeficiency. Heterozygous de novo mutations, c.1847_1849delAAG (p.E616del) and c.1276T>C (p.C426R), in the STAT3 gene were found. Functional in vitro studies of these variants are presented.Objective and hypotheses: We...

Objective: To explore the value of continuous hemodiafiltration in rescuing children with severe diabetic ketoacidosis.Method: Two children with severe diabetic ketoacidosis were studied in regard to clinical manifestation, laboratory examination and treatment and of the relevant literature was reviewed.Result: Case 1 was a girl of 13 years 5 months old, who was diagnosed as ‘Type 1 diabetes mellitus, Diabetic ketoacidosis and...

Background: Technology applied to type 2 diabetes (T2D) is an area of investigation with important clinical applications.Objective and hypotheses: There are three issues which should be considered: is continuous subcutaneous insulin infusions (CSII) effective for treatment of T2D? What is the level of satisfaction and quality of life in T2D patients using CSII? Are CSII and glucose monitoring in T2D relevant from an economic perspective?<p class="abs...

Background and Aims: A congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders in which enzymes in the cortisol biosynthesis pathways are interrupted by gene mutations. More than 90% of CAH, is caused by 21-hydroxylase (21OHD) deficiency. The 17α-hydroxylase (17OHD) deficiency one of the less common forms of CAH, can result in significant morbidity and mortality if left untreated, thus making early diagnosis essential. In Saudi A...

Introduction: McCune-Albright syndrome (MAS) is caused by somatic mosaic mutations in the GNAS gene. Detection of the GNAS mutations is usually difficult because of the low frequency mosaicism. Droplet digital polymerase chain reaction (ddPCR) is a new technology that enables to measure absolute quantities of target nucleic acids in a sample by counting nucleic acid molecules encapsulated in discrete water-in-oil droplet partitions.<p cla...

Background: Liquid chromatography-mass spectrometry (LC-MS) based panels of steroid hormones and their precursors offer a distinct pattern of steroid metabolome for various disorders of adrenal and gonadal steroidogenesis. However, it may not be easy to handle this high throughput data rapidly in clinical setting which requires expert opinion for correct interpretations. Analytical results of steroid panelling can be allied to automated review systems to simpl...

Hypophosphatasia is a rare disease caused by mutations in the gene encoding tissue- nonspecific isoenzyme of alkaline phosphatase. Duplications of the ALPL gene account for fewer than 1% of the mutations causing HPP. It has been shown that asfotase alfa treatment mineralizes the skeleton and improves respiratory function and survival in severe forms of hypophosphatasia.The newborn was evaluated for respiratory failure and generalized hypoton...

The ultimate therapy for type 1 diabetes is the replacement of the lost insulin producing cells instead of the actual life-saving but imperfect substitution of insulin. The isolation of embryonic stem cells (ESC) and later the reprogramming of somatic cells into induced pluripotent stem cells (iPSC) raised enormous hopes for cell based therapies in diabetes type 1. The first important stage in the differentiation process of ESC/iPSC is the generation of definite endoderm that ...
