Renal medullary carcinoma (RMC) is a rare and aggressive malignant epithelial neoplasm of the kidney. It almost exclusively affects children and young adults with a sickle cell trait or sickle cell disease. The majority of RMC patients present with widely disseminated disease at the time of diagnosis. Herein, we report two cases of young African-American patients with history of sickle cell tra...

heterozygous and homozygous states to explain the symptomless sickle cell trait and the true sickle cell anaemia. An individual receiving the haemoglobin S gene from one parent only (the heterozygous state A/S) would have the sickle cell trait, whereas if the gene should be received from both parents (the homozygous state 5/5) he would have sickle cell anaemia (Fig. I). Sickle cell anaemia and ...

Background: Molecular genetic factors regulating hemoglobin F (Hb F) expression are important modifiers of the severity of sickle cell anemia (SS). Methods: The prevalence of XmnI polymorphic site, the Gg:Ag ratio and the Hb F level were determined using PCR-RFLP procedure, HPLC and alkaline denaturation method, respectively, in various haplotypes of 52 patients with SS, 18 patients with sickle...

Individuals who carry the sickle cell trait (S-gene) have a greatly reduced risk of experiencing symptomatic malaria infections. However, previous studies suggest that the sickle cell trait does not protect against acquiring asymptomatic malaria infections, although the proportion of symptomatic infections is up to 50% in areas where malaria is endemic. To examine the differential impact of the...

BACKGROUND & OBJECTIVE Iron deficiency anaemia (IDA) is uncommon in individuals with sickle cell disease (SCD) because of availability of an adequate iron source potentially from increased red cell turnover and from blood transfusions. Also, iron deficiency anaemia can often go unnoticed because the sickle cell disease patients are already anaemic. Iron deficiency in sickle cell patients may re...

background: molecular genetic factors regulating hemoglobin f (hb f) expression are important modifiers of the severity of sickle cell anemia (ss).   methods: the prevalence of xmni polymorphic site, the g g: a g ratio and the hb f level were determined using pcr-rflp procedure, hplc and alkaline denaturation method, respectively, in various haplotypes of 52 patients with ss, 18 patients with s...

abstract background prevalence of hereditary blood diseases such as sickle cell anemia, sickle thalassemia and thalassemia major are high in khuzestan province. sickle cell anemia and beta-thalassemia are predominantly common in iranian arabs. pulmonary complications account for a large proportion of morbidity and mortality in patients with and sickle cell disease. periodic lung function assess...
