Practice patterns and clinical outcomes of platelet alloimmunization in a comprehensive cancer center.

Background: Platelet transfusion refractoriness (PTR) secondary to human leukocyte antigen (HLA) alloimmunization is a challenge in the treatment of hematology-oncologypatients and increases the risk of morbidity and mortality from bleeding events. Guidelines for treating PTR have not been clearly described in literature. We aim to describe the practice patterns for the management of PTR secondary to HLA alloimmunization, and to assess the mortality, thrombosis and bleeding-related clinical outcomes at 30 days from diagnosis.

Role of vena cava filters for the management of cancer-related venous thromboembolism: Systematic review and meta-analysis.

Background: Results from cohort studies evaluating the benefit in prevention of recurrent Venous Thromboembolism in cancer population are heterogeneous and controversial.

Objective: To determine the effectiveness and harms of vena cava filters alone or combined with anticoagulation to prevent the risk of recurrent venous thromboembolism in patients with cancer-related venous thromboembolism.

Materials And Methods: A search strategy was conducted in the MEDLINE, CENTRAL, EMBASE and LILACS databases.

The unusual nutritional and toxin-related underproduction anemias: approaching the riddle beyond iron, cobalamin, and folate.

"Anemias beyond iron, vitamin B12, and folate deficiencies" covers a wide array of everything which lies beyond commonly seen anemias caused by deficiencies of three micronutrients. Although anemias due to deficiencies of iron, B12, and folate are common in daily practice and account for at least one-third of anemia etiologies in older adults, it is not uncommon to encounter other nutritional and toxin-induced underproduction anemias. The combination of thorough clinical examination, careful peripheral blood smear review, and judicious selection of supporting laboratory studies is typically sufficient to make an assertive diagnosis of those cases.

Challenging clinical presentations of pernicious anemia.

Pernicious anemia (PA) is an autoimmune disease of multifactorial etiologies characterized by autoimmune chronic atrophic gastritis, cobalamin deficiency (CD) due to defective absorption of dietary cobalamin from the terminal ileum, and by the presence of intrinsic factor and parietal cell antibodies. PA is a very common cause of CD-related anemia worldwide. Despite advances in the understanding molecular biology and pathophysiology of PA, the diagnosis of PA remains challenging in many circumstances for many clinicians because of its diverse clinical manifestations and the limitations of currently available diagnostic tools.

Rituximab, etoposide, methylprednisolone, high-dose cytarabine, and cisplatin in the treatment of secondary hemophagocytic lymphohistiocytosis with classical Hodgkin lymphoma: a case report and review of the literature.

Background: Hemophagocytic lymphohistiocytosis is becoming an increasingly recognized disorder in adults. Classical Hodgkin lymphoma is a relatively uncommon etiology of hemophagocytic lymphohistiocytosis and may complicate treatment options. Rituximab, etoposide, methylprednisolone, high-dose cytarabine, and cisplatin are discussed here as a treatment regimen.
