1

disseminated intravascular coagulation (DIC)

abnormal activation of the proteins involved in blood coagulation, causing small blood clots to form in vessels and cutting off the supply of oxygen to distal tissues

2

graft rejection

process in which a recipient's immune system attacks a transplanted organ or tissue

3

graft-versus-host disease (GVHD)

complication that occurs following a stem cell or bone marrow transplant in which the transplant produces antibodies against recipient's organs that can be severe enough to cause death

4

hematoma

localized accumulation of blood, usually clotted, in an organ, space, or tissue due to a break in or severing of a blood vessel

5

hemoglobinpathy

any disorder caused by abnormalities in the hemoglobin molecule

6

lymphadenopathy

any disease of the lymph nodes

7

lymphedema

swelling, primarily in a single arm or leg, due to an accumulation of lymph within tissues caused by obstruction or disease in the lymph vessels

8

multiple myeloma

malignant tumor of plasma cells (cell that help the body fight infection by producing antibodies) in the bone marrow

9

sepsis

presence of bacteria or their toxins in the blood; also called septicemia or symptoms are limited to the skin

10

systemic lupus erythematosus (SLE)

widespread autoimmune disease that may affect the skin, brain, kidneys, and joints and causes chronic inflammation; also discoid lupus if symptoms are limited to the skin

11

thrombocythemia

overproduction of platelets, leading to thrombosis or bleeding disorders due to platelet malformations

12

thrombocytopenia

abnormal decrease in platelets caused by low production of platelets in the bone marrow or increased destruction of platelets in the blood vessels (intravascular), spleen (extravascular), or liver (extravascular)

13

immunotherapy

any form of treatment that alters, enhances, stimulates or restores the body's natural immune mechanisms to treat disease

14

allergy

injection with increasing strengths of the offending antigen given over a period of months or years to increase tolerance to an antigen responsible for severe allergies

15

biological

use of immune system stimulators to enhance the immune response in the treatment of certain forms of cancer, rheumatoid arthritis, and Crohn disease, also called biologic therapy or biotherapy

16

bone marrow aspiration

removal of a small sample of bone marrow using a thin aspiration needle (usually from the pelvis) for microscopic examination

17

bone marrow transplant

infused of healthy bone marrow stem cells after the diseased bone marrow is destroyed by chemotherapy and/or radiation therapy; used to treat leukemia aplastic anemia, and certain cancers

18

autologous

infusion of the patients own bone marrow or stem cells after a course of chemotherapy and/or radiation therapy

19

homologous

infusion of bone marrow or stem cells from a compatible donor after a course of chemotherapy and/or radiation; also called allogenic transplant

20

lymphadenectomy

removal of lymph nodes, especially in surgical procedures undertaken to remove malignant tissue

21

sentinel node excision

removal of the first node (sentinel node) that receives drainage from cancer-containing areas and the one most likely to contain malignant cells

22

transfusion

infusion of blood or blood products from one person (donor) to another person (recipient)

23

antinuclear antibody

test to identify antibodies that attack the nucleus of the individual's own body cells (auto-antibodies)

24

blood culture

test to determine the presence of pathogens in the bloodstream

25

complete blood count

series of test that includes hemoglobin; hematocrit; red and white blood cell counts, platelet count; and differential (diff) count; also called hemogram

26

monospot

nonspecific rapid serological test for the presence of the heterophile antibody, which develops several days after infection by epstein-barr virus, the organism that caused infectious mononucleosis

27

partial thromboplastin time (PTT)

test that measures the length of time it takes blood to clot to screen for deficiencies of some clotting factors; also called activated partial thromboplastin time (APTT)

28

prothrombin time (PT)

test that measures the time it takes for prothrombin to form a clot; also called pro time

29

shilling test

test used to diagnose pernicious anemia by determining if the body properly absorbs vitamin B12 through the digestive tract

30

bone marrow magnetic resonance imaging (MRI)

highly sensitive imaging procedure that detects lesions and changes in bone tissue and bone marrow, especially in multiple myeloma
