Possible association of 3' UTR +357 A>G, IVS11-nt 93 T>C, c.1311 C>T polymorphism with G6PD deficiency.

Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common X-linked inherited enzymopathic disorder affecting more than 500 million people worldwide. It has so far been linked to 217 distinct genetic variants in the exons and exon-intron boundaries of the G6PD gene, giving rise to a wide range of biochemical heterogeneity and clinical manifestations.

Objectives: Reports from different settings suggested the association of intronic and other mutations outside the reading frame of the G6PD gene with reduced enzyme activity and presenting clinical symptoms.

Favism, the commonest form of severe hemolytic anemia in Palestinian children, varies in severity with three different variants of G6PD deficiency within the same community.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common genetic abnormality known to predispose to acute hemolytic anemia (AHA), which can be triggered by certain drugs or infection. However, the commonest trigger is fava beans (Vicia faba) ingestion, causing AHA (favism), which may be life-threatening especially in children. G6PD deficiency is genetically highly heterogeneous, as nearly 200 different mutations have been observed.

Molecular heterogeneity of glucose-6-phosphate dehydrogenase deficiency in Gaza Strip Palestinians.

Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency, affecting more than 500 million people worldwide, is one of the most common of inherited disorders. There are 186 G6PD mutations published, with mutational clustering within defined ethnic/racial groups. However comprehensive molecular characterization of ethnically associated G6PD mutants and their clinical implications are lacking.

Prevalence of Chlamydia trachomatis among women attending gynecology and infertility clinics in Gaza, Palestine.

Background: Chlamydia trachomatis is an obligate intracellular bacterium characterized by a biphasic developmental cycle of replication. The organism is recognized as one of the major causes of sexually transmissible human bacterial infection throughout the world. Since there have been no previous studies dealing with chlamydial diagnosis in Palestine, this study was conducted to determine the prevalence of C.

Detection of Chlamydia trachomatis and Mycoplasma hominis, genitalium and Ureaplasma urealyticum by polymerase chain reaction in patients with sterile pyuria.

Purpose: Chlamydia trachomatis and Mycoplasma hominis, Mycoplasma genitalium, and Ureaplasma urealyticum are associated with various diseases of the urogenital tract, but they are usually not detected by routine microbiological diagnosis. To determine the occurrence of Chlamydia trachomatis, Mycoplasma hominis, Mycoplasma genitalium, and Ureaplasma urealyticum in patients with sterile pyuria.

Material/methods: Sterile pyuria urine samples collected during the period from February 2006 to April 2007 were tested by polymerase chain reaction (PCR) for the presence of C.

Entamoeba histolytica or Entamoeba dispar among children in Gaza, Gaza Strip?

Most physicians in Gaza prescribe medicaments for patient's suffering from Entamoeba histolytica/dispar without parasitologic diagnosis. Additionally, stool analysis performed by the routine methods usually reports the species as E. histolytica without con-firmation.
