  Lancet - Evidence Supports Association Between Leukemia And Exposure To Cosmic Radiation In Aircrew Harvey McConnell / ...   (Site not responding. Last check: 2007-10-12)
Deletion or loss of chromosome 7 was found in four of seven aircrew with myelodysplasia or acute myeloid leukaemia, and in eight of 19 patients with the disorders after radiotherapy alone.
We studied the karyotypes of seven aircrew treated for myelodysplasia or acute myeloid leukaemia between 1987 and 1999 (table 1), and compared them with the karyotypes, previously published, of 19 cases of myelodysplasia or acute myeloid leukaemia after radiotherapy alone at one of our institutions between 1980 and 1998 (table 2).
Compared with unselected patients with myelodysplasia or acute myeloid leukaemia, a significant excess of chromosome 7 abnormalities was found in aircrew with leukaemia (p=0·004, Fisher's exact test, two-sided) as well as in the 19 patients with leukaemia related to radiotherapy (p<0·001).

 NoBlood - View Single Post - treatment for myelodysplasia
Myelodysplasia (MDS) refers to a group of disorders in which the bone marrow does not function normally and produces insufficient number of normal blood cells.
About 50 percent of pediatric myelodysplasia can be classified in five types of MDS: refractory anemia, refractory anemia with ring sideroblasts, refractory anemia with excess blasts, refractory anemia with excess blasts in transformation, and chronic myelomonocytic leukemia.
Therefore, a topotecan and thalidomide combination therapy is promising, although further studies are needed to determine the optimum doses and schedule.

 'Common' Uncommon Anemias - February 15, 1999 - American Academy of Family Physicians
Iron deficiency was under-recognized because of an insufficient history, a lack of stool examination for blood or poor responses to iron therapy because of continued blood loss or the suboptimal use of iron supplements.
Such cells can be seen in patients with myelodysplasia; however, they are nonspecific and can also appear in patients with folic acid and vitamin B12 deficiency, thyroid deficiency, myeloproliferative diseases, uremia and hereditary hypersegmentation.
This cell is a bilobular polymorphonuclear leukocyte that may occur on a congenital basis (without clinical significance) or may be acquired in myelodysplasia, in myeloproliferative diseases or with toxic stress on the bone marrow, as a result of treatment with chemotherapeutic drugs.

 Glossary M - Randy Ramage's Aplastic Anaemia and Myelodyplasia Glossary
Myelodysplasia is generally a disease of the elderly, and may also be seen after chemotherapy for cancer.
As one might expect, the overgrowth of one type of cell often develops into leukaemia, which is a cancer of a bone marrow cell type.
Because the anaemia in myelodysplasia cannot usually be treated, except by bone marrow transplant, it is often necessary to give people with this condition repeated blood transfusions.

Myelodysplasia is thought to result from an immune system abnormality in which cells called lymphocytes attack the marrow's blood-forming cells.
Various therapies, such as blood transfusions for anemia and bleeding, antibiotics for infection, chemotherapy and bone marrow transplantation are used to treat myelodysplasia, but all have disadvantages and some carry serious risks.

This information explains the role of the skin and the causes (“risk factors”) of skin breakdown in children with myelodysplasia.
Because of the possibility of decreased sensation and movement, those with myelodysplasia are often at high risk for skin irritation and pressure sores.
Prominent, bony parts of the body are the most likely places for pressure sores to form because these places have the least amount of cushioning between the bones and the skin.

Myelodysplasia is a diagnosis of exclusion and must be made after proper determination of iron stores, vitamin deficiencies, and nutrient deficiencies are ruled out.
All of these conditions are characterized by abnormalities in the production of one or more of the cellular components of blood (red cells, white cells other than lymphocytes and platelets or their progenitor cells, megakaryocytes).
