The capacity of busulfan and total body irradiation to ablate hematopoietic stem cells as preparation for the allogeneic bone marrow transplantation of patients with congenital bone marrow disorders was studied. Fourteen patients received 18 transplants; busulfan was used in the preparatory regimen of eight transplants and total body irradiation in the regimens of six transplants. Sustained hem...
Recent observations have underscored the biologic relevance of intratumoral angiogenesis and its potential impact on prognosis. Increased bone marrow angiogenesis has been demonstrated in a variety of hematologic disorders, including multiple myeloma. The extent and prognostic significance of bone marrow angiogenesis in 114 patients with myelofibrosis with myeloid metaplasia (MMM) was investiga...
Thalassemia is a group of hereditary hemoglobin disorders characterized by insufficient production at least one globin chain, resulting in unbalanced chains. Homozygous mutations the β-globin gene, absence β-chain, are main cause β-thalassemia major. Because β-chain major not formed, there an accumulation free α-chains red blood cells, which can trigger apoptosis and hemolysis ineffective eryth...
A simple, routine procedure for water miscible glycol methacrylate (GMA) embedding of undecalcified bone marrow cores, which preserves the activity of enzymes useful in diagnosing various haematopoietic disorders, is described. The GMA used in this study has a low acid content that eliminates background staining, and the modified May-Grünwald-Giemsa stain provides good definition and excellent ...
Osteopetrosis is a rare metabolic bone disease characterized by generalized increase in skeletal mass. About 500 cases have been described in the literature. This disorder presents. In one of three forms: Osteopetosis Tarda , Osreopetrosis Congenital and “marble bone” disease. Osteopetrosis congentia results in bone marrow failur and is almost always fatal. Marble bone disease causes short st...
Hemorrhagic complications related to bone marrow aspiration and trephine biopsy are uncommon. Risk factors include thrombocytopenia, myeloproliferative disorders, concurrent use of anticoagulants, and obesity. Here we describe our technique for bone marrow aspiration and biopsy of the posterior iliac crest using CT guidance. Our technique ensures needle passage only through subcutaneous fat and...
Cold agglutinin disease (CAD) is a well-recognized complication of lymphoproliferative disorders. It has been previously recognized that cases of primary CAD frequently exhibit underlying malignant lymphoma in the bone marrow. Lymphoplasmacytic lymphoma is the most common subtype of malignant lymphoma; however, diffuse large B-cell lymphoma (DLBCL) has also been documented, albeit extremely rar...
