Extradural hematoma (EDH) in absence of trauma is a rare entity with only few cases reported in literature. The various causes reported include: Vascular malformation of dura, coagulopathies, sinus infection, middle ear or orbital infection, and tumor. Occurrence of spontaneous EDH as a complication of sickle cell disease is even much rarer. We report a case with sickle cell disease who presented with spontaneous extradural and subgaleal hematomas following an episode of vaso-oclusive crisis. He was managed successfully with surgery...

BACKGROUND: MR imaging is used to assess iron overload in patients with hemoglobinopathies and in those who have undergone multiple blood transfusions. Sometimes splenic nodules are found incidentally on these examinations and this may cause diagnostic uncertainty. OBJECTIVE: To determine the prevalence, imaging characteristics and evolution of splenic nodules found on MR imaging for iron overload evaluation. MATERIALS AND METHODS: Retrospective review of all MR imaging examinations performed for iron overload assessment from 2005 to 2015 in a tertiary pediatric hospital...

Renal medullary carcinoma (RMC) is a rare, highly aggressive tumor recognized as an independent pathological entity. African-descent adolescents and young adults with sickle cell hemoglobinopathy are the most affected groups. This rare subtype of renal cell carcinoma has its own morphogenetic and pathological characteristics. The major clinical manifestations include gross hematuria, abdominal or flank pain, and weight loss. The prognosis is very poor, with 95% of cases diagnosed at an advanced stage of the disease...

This Forum addresses oxidative reactions of hemoglobin (Hb) and explores the underlying mechanisms of some of these reactions that contribute to the pathophysiology associated with hemolytic anemias and Hb-based oxygen therapeutics. A special focus of this Forum is on the understanding of naturally occurring mutations in human Hbs and how these mutations were influenced overtime by variety of oxidative stresses. What emerges from these contributions is that some hemoglobinopathies involve mutant Hbs that resist oxidative challenges whereas the majority often result in circulatory disorder...

Mutations in the HBB gene are responsible for several serious hemoglobinopathies, such as sickle cell anemia and β-thalassemia. Sickle cell anemia is one of the most common monogenic diseases worldwide. Due to its prevalence, diverse strategies have been developed for a better understanding of its molecular mechanisms. In silico analysis has been increasingly used to investigate the genotype-phenotype relationship of many diseases, and the sequences of healthy individuals deposited in the 1,000 Genomes database appear to be an excellent tool for such analysis...

β-Thalassemia and sickle cell disease (SCD) are the world's two most widely disseminated hereditary hemoglobinopathies. β-Thalassemia originated in the Mediterranean, Middle Eastern, and Asian regions, and SCD originated in central Africa. However, subsequent population migration means that these two diseases are now global and thus constitute a growing health problem in many countries. Despite remarkable improvements in medical care for patients with β-hemoglobinopathies, there is still only one definitive treatment option: allogeneic hematopoietic stem cell (HSC) transplantation...

The Kruppel-like factor 1 (KLF1) gene is an essential transcription factor that is required for the proper maturation of the erythroid cells. Recent studies have reported that KLF1 variations are associated with increased fetal hemoglobin (HbF) levels. Here we report a novel KLF1 gene variation codon 211 A→G (c.632 A>G) in a family who was referred for hemoglobinopathy screening. Both parents were classical β-thalassemia trait (mother: HbA2 4.1%, HbF 8.6%; father: HbA2 5.5%, HbF 0.6%) codon 15 G→A heterozygous, and the child was β-thalassemia homozygous...

The aim of this study was to describe the mutational spectrum of hemoglobinopathies during the period 1988-2015 in Umbria, Central Italy, which has never been considered endemic for these conditions. Twenty-four different β-globin gene mutations were identified in 188 patients and eight different α-globin gene mutations in 74 patients. Sixty percent β-thalassemia (β-thal), 85.0% sickle cell disease, 44.0% Hb S (HBB: c.20A>T)/β-thal and 85.0% compound heterozygotes for hemoglobin (Hb) variant-carrying patients were diagnosed or molecularly characterized in the last 3 years...

Mutations that cause destabilization of the hemoglobin (Hb) tetramer are a rare cause of hemolytic anemia. In contrast to the hemolytic anemia caused by enzyme deficiencies, a dominant mode of inheritance characterizes the unstable Hbs. Hb Alesha [β67(E11)Val→Met; HBB: c.202G>A] is caused by a G>A mutation at codon 67 of the β-globin gene, resulting in a valine to methionine substitution at helix E11. This replacement disrupts the apolar bonds between valine and the heme group, producing an unstable Hb and severe hemolysis...

Renal medullary carcinoma (RMC) is an uncommon aggressive neoplasm of the kidney. RMC is biologically aggressive with a very poor prognosis, and metastasis is seen in up to 95% of the patients at diagnosis or shortly thereafter. The common sites of metastasis are respectively lymph nodes, lungs, livers, and adrenal glands in order of frequency. The presence of poorly differentiated eosinophilic cells in a characteristic fibro-inflammatory stroma is seen in histological examination. The origin and pathogenesis of RMC are unclear...

INTRODUCTION: Renal papillary necrosis is not commonly seen in daily practice, but can have severe consequences when it is not diagnosed in time. It is known to be associated with sickle cell hemoglobinopathies; however a wide range of etiologies are possible, and it is therefore not the first diagnosis clinicians consider in patients with sickle cell disease who present with hematuria. METHODS: A literature search was performed to summarize the current knowledge about renal papillary necrosis associated with sickle cell disease...

BACKGROUND: Intravascular hemolysis produces injury in a variety of human diseases including hemoglobinopathies, malaria, and sepsis. The adverse effects of increased plasma hemoglobin are partly mediated by depletion of nitric oxide (NO) and result in vasoconstriction. Circulating plasma proteins haptoglobin and hemopexin scavenge extracellular hemoglobin and cell-free heme, respectively. METHODS: The ability of human haptoglobin or hemopexin to inhibit the adverse effects of NO-scavenging by circulating murine hemoglobin was tested in C57Bl/6 mice...
