David T. Teachey and Michele P. Lambert The diagnosis and management of children with autoimmune cytopenias can be challenging. Children can present with immune-mediated destruction of a single-cell lineage or multiple cell lineages, including platelets (immune thrombocytopenia [ITP]), erythrocytes (autoimmune hemolytic anemia),

and neutrophils (autoimmune neutropenia). Immune-mediated destruction can be primary or secondary to a comorbid immunodeficiency, malignancy, rheumatologic condition, or lymphoproliferative disorder. Treatment options generally consist of nonspecific immune suppression or modulation. This nonspecific approach is changing as recent insights into disease biology have led to targeted therapies, screening assay including the use of thrombopoietin

mimetics in ITP and sirolimus for cytopenias associated with autoimmune lymphoproliferative syndrome. Howard Trachtman This review describes the epidemiology, pathophysiology, presentation, clinical causes, treatment, PTC124 and long-term prognosis of pediatric patients who present with thrombotic microangiopathy. The focus is on hemolytic uremic syndrome and thrombotic thrombocytopenic purpura, the most common phenotypes of thrombotic microangiopathy. Paula H.B. Bolton-Maggs Hemovigilance is an essential part of the transfusion process and is defined as surveillance procedures covering the whole transfusion chain, from collection of blood and its components, intended to collect and assess information on unexpected or undesirable effects resulting from the therapeutic use of labile blood products and to prevent their occurrence or recurrence. The UK surveillance scheme has

collected data for 16 years and is a model demonstrating how information on adverse incidents can be used to improve patient safety, influencing the management of donors Cetuximab chemical structure and improved education and training for the many people involved in the transfusion process. Edward C.C. Wong Blood banking/immunohematology is an area of laboratory medicine that involves the preparation of blood and blood components for transfusion as well as the selection and monitoring of those components following transfusion. The preparation, modification, and indications of both traditional and newer products are described in this review, along with special considerations for neonates, patients undergoing hematopoietic stem cell transplantation, those with sickle cell disease, and others. Immunohematological techniques are critical in the provision of blood and blood products and are briefly discussed. Yeowon A. Kim and Steven R. Sloan Apheresis refers to the removal of a component of the blood and is performed using a group of medical technologies in which peripheral blood is processed by an instrument that separates the various components. The selected component is isolated while the remainder is returned to the patient.
