Term
Anemia
Definition
A decrease in the number of red blood cells circulating through the blood vessels resulting in decreased oxygen delivery to the peripheral tissues. Anemia can be associated with blood loss, red blood cell destruction and inadequate production
Term
Anemia, Aplastic
Definition
A disease characterized by pancytopenia resulting from failure of the bone marrow to producing enough red and white blood cells to keep the body healthy
Term
Anemia, Hemolytic
Definition
A disease due to hemolysis, the abnormal breakdown and premature destruction of red blood cells (RBCs)
Term
Anemia, Iron Deficiency
Definition
Anemia characterized by decreased or absent of hemoglobin levels due to lack of iron.
Term
Anemia, Pernicious
Definition
decrease in number and maturity of red blood cells (RBCs)and the formation and circulation of megaloblasts with marked poikilocytosis and anisocytosis.
Term
Anemia, Sickle Cell
Definition
A severe, chronic hereditary form of Hemolytic Anemia. The red blood cells (RBCs)become "sickled" shape in the presents of low oxygen concentration.
Term
Hemochromatosis
Definition
A metabolic disorder causing iron deposits in the body. Usualy due to complications of one of the Hemolytic Anemias
Term
Hemophilia
Definition
Hereditary genetic disorders that impair the body's ability to control blood clotting or coagulation, which is used to stop bleeding. Results in uncontrolled bleeding times.
Term
Leukemia
Definition
A type of cancer that causes uncontrolled increase of immature white blood cell (WBCs) development. Usually accompanied by infection, anemia, and impaired blood clotting.
Term
Leukemia, Acute Myelogenous (AML)
Definition
A rapidly progressing cancer of the blood in which too many immature (not fully formed) granulocytes, a type of white blood cell, are found in the bone marrow and blood.
Term
Leukemia, Acute Lymphocytic (ALL)
Definition
A condition marked by a rapid increase in the number of immature lymphocytes. It is most often diagnosed in children
Term
Leukemia, Chronic Myelogenous (CML)
Definition
A slowly progressive disease characterized by the over-production of immature and mature Granulocytes in the blood stream and the bone marrow.
Term
Leukemia, Chronic Lymphocytic (CLL)
Definition
A slowly progressing cancer of the blood that involves overproduction lymphocytes that do not mature properly then accumulate in the bone marrow, and spread via the bloodstream to accumulate in the lymph nodes, spleen, and liver.
Term
Multiple Myeloma
Definition
A malignant plasma cell neoplasm. Causes and increase in immature and immature plasma cells - Which often replace the bone marrow which destroys the skeletal structure.
Term
Polycythemia Vera
Definition
A clonal disease characterized by the over-production of red blood cells (RBCs), Granulocytes, and Thrombocytes. Resulting in an increase in the volume and viscosity(thickness) of blood.
Term
Purpura
Definition
Bleeding underneath the skin in the form of pin-head-sized hemorrhages appearing as red or purple discolorations on the skin
Term
Thalassemia
Definition
A hereditary form of Hemolytic anemias caused by the inability to produce either the alpha or beta chain of hemoglobin. Resulting in a deficianty of hemoglobin which causes hypochromic mycrocytic (RBCs)
Term
Granulocytosis
Definition
Increased number of Granulocytes in the circulating blood as a reaction to any variety of inflammation or infection.
Term
Idiopathic Thrombocytopenic Purpura
Definition
A form of Purpura associated with a reduction of blood platelets. Which can result in hemorrhages from mucous membranes and very low platelet counts.
