anisocytosis

presence of red blood cells of unequal size

bacteremia

presebce if bacteria in the bloodstream

erythropenia

an abnormally reduced number of red blood cells

hemolysis

rupture of the red blood cell membrane

hemorrhage

loss of blood from the circulation

macrocytosis

abnormally large-sized red blood cells

polycythemia

abnormal increase in the number of erythrocytes in the blood

splenomegaly

abnormal enlargement of the spleen

toxemia

presence of toxins in the blood

AIDS

acronym for acquired immune deficiency syndrome; is caused by the human immunodeficiency virus (HIV), which disables the immune reponse by destroying mainly helper T cells (which are needed for activation of B cells) the loss of immune function allows opportunistic to proliferate and eventually cause death

allergy

response to an allergen, which is an antigen that produces a hypersensitivity reaction that includes immediated inflammation but does not elicit other immune responses; allergies are of many types, the most common of which are allergic rhinitis (hay fever), which affects the mucous membranes of the nasal cavity and throa, and allergic dermatitis, which affects the skin where it has made contact with allergen

anaphylaxis

an immediate reaction to an antigen that includes rapid inflammation and systemwide smooth muscle contractions

anemia

a reduced ability of red blood cells to deliver oxygen to tissues; common forms of anemia include aplatic anemia. iron deficiency anemia, sicle cell anemia, and pernicious anemia

aplastic anemia

anemia charadcterized by the failure of red bone marrow to produce red blood cells

autoimmune disorder

anyone of several disease that are caused by a person's own immune response attacking otherwise healthy tissues, including rhematiod arthritis, systemic lupus erythematosus, and multiple sclerosis

botulism

a form of poisoning caused by the ingestion of food contaminated with the toxin produced by the bacterium clostridium botulinum

diphtheria

disease caused by a bacterium and its toxin, resulting in inflammation of mucous membranes, primarily in the mouth and throat

dyscrasia

general term for an abnormal condition of the blood

erythroblastosis fetalis

blood disorder resulting from incompatibility between a fetus with Rh positive blood and its mother with Rh negative blood, which causes the destruction of fetal red blood cells, and requires blood transfusions to save the fetus; also known as Rh mismatch or hemolytic disease of newborn

fungemia

Fungal infection distributed by way of the bloodstream.

gas gangrene

infection of a wound caused by various anaerobic bacteria; produces a fermentation gas, necrosis, and septicemia

hemochromatosis

inherited disorder that results in an excessive accumulation of iron deposits in the body

hemophilia

inherited bleeding disorder that results from defective clotting proteins involved in blood coagulation

hodgkin's disease

cancer of lymphatic tissue; characterized by the progressive enlargement of lymph nodes, fatigue, and deficiency of the immune response

immunodeficiency

condition that results from a defective immune response

immunosuppression

reduction of the immune response caused by disease or, in the case of organ transplants, by the use of chemical, pharmocologic, pharmacologic, physical, or immunologic agents

infection

multiplication of disease-causing microorganisms within the body

inflammation

a swelling of body tissue caused by the movement of plasma into the extracellular space to produce edema or fluid accumulation, in tissue; the protective response of body tissues to irritation or injury; symptoms include swelling, redness, heat, and pain

influenza

a viral disease characterized by a temporary inflammation of mucous membranes and fever; commonly called "the flu," the virus is highly contagious and is capable of mutating to escape detection by white blood cells

iron deficiency anemia

anemia that is caused by a lack of iron, which results in smaller red blood cells containing deficient levels of hemoglobin

leukemia

cancer of the red bone marrow, which is the blood-forming tissue; charaterized by an increase number of white blood cells, many of which are abnormal and nonfunctional

lymphadenitis

inflammation of the lymph nodes

lymphadenopathy

literally, disease of the lypmph nodes; this general term is often applied to a syndrome, lymphadenopathy syndrome which is a persistent swelling of the lymph nodes that often precedes the onset of AIDS

lymphoma

tumor that originates in lymphatic tissue

malaria

disease caused by a parasitic protozoan that infects red blood cells and is carried by Anopheles mosquitoes; characterized by periodic fevers and fatigue

mononucleosis

viral disease characterized by enlarged lynph nodes, atypical lymphocytes, sore throat, fever, and fatigue

myelodysplasia

bone marrow disorder characterized by the proliferation of abnormal stem cells; usually develops into a form of leukemia

nosocomial infections

disorder that usually consists of bacterial infections contracted furing a hospital stay; often due to antibiotic- resistant strains of staphylococcus

pernicious anemia

anemia caused by an insufficiency of vitamin B12, resulting in red blood cells that are large, varied in shape, and reduced in number

plague

any infectious disease of wide prevalence or excessive mortality; also refers specifically to an acute infectious disease caused by the bacterium Yersinia pestis that is characterized by high fever, skin eruptions, internal hemorrhage, and peumonia, whic is also called bubonic plague

rabies

a virus infection spread from the mouth of an infected animal, usually by way of a bite; the virus produces a neurotoxin that acts on the centeral nervous system and os highly fatal

septicemia

systemic disease caused by the presence of bacteria and their toxins in the circulating blood; a person suffering from this is referred to as "septic"

sicle cell anemia

inherited, chronic anemia characterized by defective hemoglobin that causes red blood cells to become misshapen (sicle-shaped), resulting in drowsiness, leg ulcerations, fever, joint and abdominal pain, and thrombosis

staphylococcemia

presence of Staphylococci bacteria in the blood, which is the literal meaning of the term; commonly called a staph infection, it is a frequent complication to normal healing and is also the most common cause of food poisoning, skin inflammation osteomyelitus, and nosocomial infections

tetanus

a disease caused by a powerful neurotoxin released by the common bacterium clostridium tetani; the toxin acts upon the central nervous system to caused convulsions and paralysis

thymoma

tumor that originates in the thymus gland
