The first stage is an oedema of the bone marrow initiated by a bone infarct, which is itself modulated by numerous causes, leading to myelofibrosis as a result of hypoxia and gradual loss of bone density characteristic of ischaemic osteoporosis. Further deterioration can be triggered by additional bone infarcts leading to anoxia and localized ...
A needle used for bone marrow aspiration, with removable stylet. Bone marrow aspirate. A bone marrow biopsy may be done in a health care provider's office or in a hospital. Informed consent for the procedure is typically required. The patient is asked to lie on their abdomen (prone position) or on their side (lateral decubitus position).
A Wright's-stained bone marrow aspirate smear from a patient with leukemia. Bone marrow examination is the pathologic analysis of samples of bone marrow obtained via biopsy and bone marrow aspiration. Bone marrow examination is used in the diagnosis of a number of conditions, including leukemia, multiple myeloma, anemia, and pancytopenia.
Hematopoietic stem cell transplantation. Hematopoietic stem-cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood, in order to replicate inside a patient and produce additional normal blood cells. [1][2][3][4][5][6] HSCT may be ...
Haematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent haematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. [10][11][12] It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an identical ...
Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to more porous bone, and consequent increase in fracture risk. It is the most common reason for a broken bone among the elderly. [3]
A bone marrow transplant is the process in which a patient has an infusion of healthy stem cells — the immature cells that develop into red blood cells, white blood cells and platelets — to ...
Osteoporotic bone marrow defect. Osteoporotic bone marrow defect is a condition which may be found in the body of the mandible. It is usually painless and found during routine radiographs. It appears as a poorly defined radiolucency (dark area) where there was a previous history of an extraction of a tooth. It may resemble a metastatic disease.
