CH 14 LYMPH PATHO Flashcards
severe combined immunodeficiency disease
SCID immunodeficiency at birth where infants are born with deficient B and T cells which results in a lack of immunity
group of clinical signs and symptoms associated with suppression of the immune system and marked by opportunistic infections, secondary neoplasms, and neurological problems
acquired immunodeficiency syndrome AIDS
destroys helper T cells (CD4+ cells) and lowers immunity, causes AIDS and opportunistic infections due to low immunity
HIV human immunodeficiency virus
yeast like fungus normally present in mouth, skin, intestinal tract, vagina, overgrows, casuing infection of the mouth, respiratory tract or skin
candida candidiasis
yeast like fungus causes lung, brain, and blood infections. pathogen is found in pigeon droppings and nesting places, air, water and soil
cryptococcal infection (crypto) cryptococcus
parasitic infection of the gastrointestinal tract and brain and spinal cord. the pathogen, cryptosporidium, is a one-celled organism commonly found in farm animals
cryptosporidiosis
virus that causes enteritis and retinitis, (inflammation of the retina at the back of the eye). found in saliva, semen, cervical secretions, urine, feces, blood, and breast milk, but usually only causes disease when the immune system is compromised
cytomegalovirus infection CMV
viral infection causes small blisters on the skin of the lips or nose or on the genitals. also causes encephalitis
herpes simplex virus
fungal infection caused by inhalation of dust contaminated with histoplasma capsulatum; causes fever, chills, lung infections. pathogen is found in bird and bat droppings.
histoplasmosis / histo
bacterial disease manifesting with fever malaise night sweats anorexia diarrhea weight loss and lung and blood infections
mycobacterium avium-intracellulare complex infection MAI
one-celled organism causes lung infection, with fever, cough, and chest pain. pathogen is found in air, water, and soil and is carried by naimals
pneumocystis pneumonia PCP
parasitic infection involving the central nervous system and causing fever, chills, visual disturbances, confusion, hemiparesis, and seizures. eating raw uncooked pork or lamb, unpasterurized products or raw eggs/veggies
toxoplasmosis Toxo
bacterial; disease involving the lungs, brain, and other organs. signs and symptoms are fever, cough, loss of weight, anorexia and blood in sputum
tuberculosis TB caused by mycobacterium tuberculosis
a cancer arising from the lining of capillaries that produce dark-purplish skin nodules
kaposi sarcoma
cancer of lymph nodes
lymphoma
weight loss and decrease in muscular strength, appetite, and mental activity
wasting syndrome
persons who have HIV antibodies in their blood
HIV positive
found in blood, semen, saliva, cervical secretions, and other body fluids and can transmit via sexual, blood or other fluids
hiv
drug used to treat AIDS that is an inhibitor of of a viral enzyme called RT
reverse transcriptase inhibitor RTI’s
another class of anti-HIV drugs that inhibit protease which HIV needs to reproduce
protease inhibitors
highly active antiretroviral therapy
HAART
abnormal hypersensitivity acquired by exposure to an antigen
allergy all/o = other
in which and extraordinary hypersensitivity reaction occurs throughout the body leading to fall in blood pressure, shock, respiratory distress, edema
systemic anaphylaxis
fall in blood pressure
hypoetension
allergies of pollen, dust, molds
asthma
caused by allergens in food or drugs
hives
rash from soaps cosmetics or chemicals
atopic dermatitis
malignant tumor of lymph nodes and lymph tissue
lymphoma / cancer
malignant tumor of lymphoid tissue in spleen and lymph nodes
hodgkin lymphoma
lymph nodes enlarged
lymphadenopathy
a malignant cell in the lymph nodes that helps diagnose hodgkin lymphona
reed sternberg cell
mostly b cell lymphomas and rarely t cell malignancies, this disease can be cured or stopped by chemo.
non hodgkin lymphoma
composed of collections of small lymphocytes in a follicle or nodule arrangement
follicular lymphoma
composed of large lymphocytes that infiltrate nodes and tissues diffusely
large cell lymphoma
malignant tumor of bone marrow cells
multiple myeloma
tumor of the thymus gland
thymoma
measures the number of CD4+ T cells (helper t cells) in the bloodstream of patients with AIDS
CD4+ cell count
screening test to detect anti-HIV antibodies in the bloodstream
ELISA enzyme linked immunosorbent assay
test that separates immunoglobins
immunoelectrophoresis
measurement of the amount of AIDS virus (HIV) in the bloodstream
viral load test
xray imaging produces cross sectional and other views of anatomic structures
computed tomography scan (CT)
