An epicanthic fold or epicanthus [6] is a skin fold of the upper eyelid that covers the inner corner (medial canthus) of the eye. [3] However, variation occurs in the nature of this feature and the presence of "partial epicanthic folds" or "slight epicanthic folds" is noted in the relevant literature.
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.
Bone marrow samples can be obtained by aspiration and trephine biopsy. Sometimes, a bone marrow examination will include both an aspirate and a biopsy. The aspirate yields semi-liquid bone marrow, which can be examined by a pathologist under a light microscope and analyzed by flow cytometry, chromosome analysis, or polymerase chain reaction (PCR
If a low count of reticulocytes is found, it usually indicates bone marrow stress. If a high reticulocyte count is found, it is usually linked to hemolysis, but a Coombs test may be performed in this case to rule out immune-mediated hemolysis. [4] Polychromasia can also be seen in blood smears when there is a normal reticulocyte count.
A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...
Hydroxycarbamide, interferon-α and anagrelide can lower the platelet count. Low-dose aspirin is used to reduce the risk of blood clot formation unless the platelet count is very high, where there is a risk of bleeding from the disease, and hence this measure would be counter-productive as aspirin-use increases the risk of bleeding. [3] [15 ...
Pancytopenia usually requires a bone marrow biopsy in order to distinguish among different causes. [5] anemia: hemoglobin < 13.5 g/dL (male) or < 12 g/dL (female). leukopenia: total white cell count < 4.0 x 10 9 /L. Decrease in all types of white blood cells (revealed by doing a differential count). thrombocytopenia: platelet count < 150×10 9 /L.
A high reticulocyte count signifies that bone marrow processes are normal. A low reticulocyte count would signify there is a problem at the level of the bone marrow, which produce the stem cells. Acute blood loss would result in a high reticulocyte count, as bone marrow processes are normal and the bone marrow responds accordingly to the body's ...
