Alpha/Beta T-cell Depleted Blood-forming Stem Cell Transplant From Related or Unrelated Donors for Blood Diseases in Children and Young Adults

This study is being done to see if the investigators can take peripheral blood stem cells from either an adult family member or a closely matched unrelated donor, and run them through a special lab instrument to remove alpha/beta T cells and B cells and then give them to the patient to treat disease. This is an experimental way of doing a hematopoietic stem cell transplant (HSCT). The investigators want to see if the new stem cells will grow without bad graft vs. host disease (GVHD). This treatment approach is experimental in the United States.

Diamond Blackfan Anemia Registry (DBAR)

The purpose of this study is to maintain a comprehensive registry of patients with the rare inherited bone marrow failure syndrome Diamond Blackfan anemia (DBA).

Role of Transcranial Doppler and Magnetic Resonance Angiography for Future Management of Sickle Cell Anemia CNS.

This study aimed to determine the Predictive Value of Transcranial Doppler and Magnetic Resonance Angiography for Future Management of Sickle Cell Anemia. Specific aims are: Demonstrate silent parenchymal and vascular brain changes that are incidentally observed in neurologically free SCD children using screening TCD and MRA in Pediatric Hematology unit at Assiut University Hospital Detect any abnormality with vasculopathy, arterial occlusion and old SCI. Strokes in children with SCD can be prevented by checking a transcranial Doppler (TCD) ultrasound,MRA and providing blood transfusions to children with abnormal blood flow on the TCD and detect Silent cerebral and cerebrovascular changes in SCD.

Collection and Distribution of Biospecimens for Novel Research Uses

iSpecimen aims to create a clinical partner network of hospitals, laboratories, academic institutions, and other healthcare organizations ("institutions") capable of providing researchers and educators ("researchers") with annotated biospecimens for use in biomarker discovery and validation; diagnostic test and instrumentation development and validation; therapeutics development; other medical research including the impact that various specimen collection and handling methods and conditions have on research results; and in education such as researcher or physician training (collectively "research").
