- Cell Mediated Immunity
- Type 4 (Hypersensitivity reaction)
- Disease consequences
- Tumor Lysis Syndrome
- Type 1 (Hypersensitivity reaction)
- a Involves WBCs, natural killer cells, & cytokines
Provides for self and nonself recognition
Critical role in preventing cancer development
Transplant rejection (a protective response)
- b Rapid Hypersensitivity (Humoral)
Can be local or systemic
Allergens inhaled, ingested, contacted or injected
Reaction comes from within.
Reaction involves IgE, mast cells, chemical mediators.
- c Cell Mediated Response (Delayed Hypersens.)
Recognition and response of T lymphocytes to foreign antigen (external or internal)
Antibody and complement system are not involved.
Mediators: Cytokines, T cytotoxic cells, monocytes/macrophages, lysosomal enzymes
EX: allergic contact dermatitis, transplant rejection
- d oncologic emergency with rapid lysis of malignant cells, as the cells lyse, intracellular contents are released in blood which results in hyperkalemia, hyperphosphaemia, and hyperuricemia which puts the patient at risk for renal failure and cardiac function, early signs include n&v, anorexia, diarrhea, muscle weakness and cramping, later signs tetany, paresthesias, seizures, anuria, and cardiac arrest
- e decreased immunity & blood producing functions, altered GI structure and function, motor and sensory deficits, decreased respiratory function
5 Multiple choice questions
- androgens, estrogen, progestin, LHRH
- Compression/obstruction by tumor growth, painful -/+ life threatning emergency.
Signs include: edema, Stoke's sign, dyspnea, erythema, and epistazis
- Immature and primitive, undifferentiated (no function), anaplasia
- What type of reaction would a transfusion elicit?
- Plasma, Interstitial fluid;crosses the placenta. Most dominant response in second exposure
5 True/False questions
Neumega → What med is given to stimulate platelet production?
Grade I → Very abnormal, poorly differentiated; severe dysplasia
Karnofsky Performance Scale → Self exam, avoidance of known or potential carcinogens, modification of associated factors & remove "at risk" tissues, Chemoprevention (asprin/day), Vaccination
SIADH (syndrome of inappropriate anti-diuretic hormone) → this results from an excess of ADH (Antidiuretic Hormone). The POSTERIOR pituitary gland continues to release ADH, causing the kidneys to reabsorb excess water, which decreases urine output & increases fluid volume. Client will have hyponatremia, water retention, weight gain, concentrated urine, muscle cramps & weakness. The low osmolality of blood allows fluid to leak out of vessels & causes brain swelling.
mast cell stimulating meds → inhibit release of histamine
