Primary bone marrow edema is also referred to as spontaneous bone marrow edema, or bone marrow edema syndrome (BMES). This category of BME does not have a particular cause but is self-limiting in nature, meaning that symptoms usually resolve by themselves within three to nine months after onset without pathological consequences.
Bone marrow is a semi-solid tissue found within the spongy (also known as cancellous) portions of bones. [2] In birds and mammals, bone marrow is the primary site of new blood cell production (or haematopoiesis). [3] It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells.
The vertical parasagittal planes correspond to the region of maximal stress during walking, while the horizontal fracture develops later, secondary to the loss of lateral support by parasagittal fractures. MRI is the primary imaging technique in this case, with the most common MRI pattern showing bone marrow edema and a fracture line (Figure 12).
Primary polycythemias are myeloproliferative diseases affecting red blood cell precursors in the bone marrow. Polycythemia vera (PCV) (a.k.a. polycythemia rubra vera (PRV)) occurs when excess red blood cells are produced as a result of an abnormality of the bone marrow. [3] Often, excess white blood cells and platelets are also produced.
In oncology, polycythemia vera (PV) is an uncommon myeloproliferative neoplasm in which the bone marrow makes too many red blood cells. [1] The majority of cases [2] are caused by mutations in the JAK2 gene, most commonly resulting in a single amino acid change in its protein product from valine to phenylalanine at position 617.
Myelodysplastic syndrome (MDS) is a form of blood cancer in which the bone marrow no longer produces enough healthy, normal blood cells. [9] MDS are a frequently unrecognized and rare group of bone marrow failure disorders, yet the incidence rate has rose from 143 reported cases in 1973 to approximately 15,000 cases in the United States each year.
Prolonged use of an IO site, lasting longer than 24 hours, is associated with osteomyelitis (an infection in the bone). [3] Intraosseous infusion-- needle insertion into anterior tibia. The needle is inserted through the bone's hard cortex and into the soft marrow interior, which allows immediate access to the vascular system. The IO needle is ...
Endothelial stem cells (ESCs) are one of three types of stem cells found in bone marrow. They are multipotent, which describes the ability to give rise to many cell types, whereas a pluripotent stem cell can give rise to all types. ESCs have the characteristic properties of a stem cell: self-renewal and differentiation.
