Dismielopoetik syndrome (TBS) primer is a syndrome in which mark by dysplasia of the hemopoietic system (dysmyelopoesis, dyserthoropoesis, and dysthrombopoesis), either single or mixed disorder, accompanied by maturation and differentiation previously unknown.
If the cause is known is called the secondary, for example, HUMAN RESOURCE deficiency of vitamin B12 or folic acid deficiency, cytostatic treatment, and so on.
TBS generally occur in old age with a mean age of 60-75 years; men slightly more often than women and the cause is still unknown.
Primary HUMAN RESOURCES include diseases that were previously referred to as preleukemia, smoldering oligoblastic leukemia, leukemia, hemopoietic dysplasia, myelodysplastic syndrome, primarily acquired sideroblastic anemia.
Its clinical manifestations are caused due to the cytopenia, a single or a combination of both, i.e. complaints anemia who disobey, bleeding due to trombopeni, and the presence of granulocytopenia with all its repercussions. 1

Aplastic anemia and Myelodysplastic Syndrome is a condition that affects the bone marrow and blood cells it produces. Bone marrow is the spongy tissue as found in bone such as the sternum, ribs, pelvis, spine, and skull.
This resulted in the original (stem) cells that undergo cleavage to generate myeloid stem cells. Myeloid stem cells are cells that produce red blood cells, white blood cells, and platelets.
In Myelodysplastic Syndrome (MDS), there was a decrease in the production of myeloid blood cells by the bone marrow while aplastic anemia is a condition in which bone marrow is damaged causing a decrease in the production of new blood cells...
In the MDS, the bone marrow produces blood cells are abnormal and deformed but recently while in aplastic anemia, the bone marrow stops producing new blood cells.
MDS generally strikes men over 60 years of age group whereas aplastic anemia is usually seen in adolescents and young adults. In the 1/3 case, the MDS can develop into acute myeloid leukemia is a cancer of the bone marrow grows fast.

Aplastic anemia and MDS is triggered because of exposure to chemotherapy/radiotherapy used in cancer, chemical substances such as benzene, and insecticides. On aplastic anemia, our immune system attacking healthy bone marrow cells and affect the production of new blood cells.
It is also caused due to infection (Hepatitis, Parvovirus B19, HIV), drug use like carbamazepine, chloramphenicol, and others while in the MDS the cause is usually unknown. MDS is considered triggered due to exposure to heavy metals (mercury/lead) and cigarette smoke.
Symptoms appear because pancytopenia looks at both these conditions. Pancytopenia is a decrease in red blood cells, white blood cells, and platelets. The decrease in red blood cells causing anemia.
Thus, sufferers experience symptoms such as fatigue, weakness, and shortness of breath. A decrease in white blood cells causes an increased tendency to develop infections. Decreased platelet count causes easy bruising and bloody i.e. e. nose bleeds, bleeding gums, etc.
The diagnosis is confirmed by an examination of the blood such as complete blood reckoning.
MDS and anemia on aplastic will show a decline in hemoglobin, red blood cells, white blood cells, and platelets.
A bone marrow biopsy will help us to distinguish between the two conditions. Here a sample of bone marrow removed from the hip bone and checked.
Anemia bone marrow shows a plastic hypocellular because the blood cells are replaced by fat while MDS are hypercellular bone marrow, and there are abnormal cells.
Treatment will depend on the patient's age, general health factors and risk factors involved. In both cases, the first given supportive care.

This includes blood transfusions and antibiotics to control the infection. On aplastic anemia, the immunosuppressant drugs are used. They were the drugs that suppress the activity of immune cells that destroy the bone marrow.
On young patients, bone marrow transplantation is very helpful. In the MDS, used a single drug or combination chemotherapy. An immunosuppressant is also very helpful.
Bone marrow transplantation is the treatment of choice but there are risk factors involved. On Aplastic Anemia, the survival rate is 5 years while in the MDS, the survival rate is 6 months to 6 years.
