Question | Answer |
---|---|
Apoptosis | Programmed natural cell death |
Angiogenesis | Creation of new blood vessels |
Alkylating Agents | Nitrogen Mustard - 1st agent used, Busulfan - anti-leukemia agent, Nitrosureas - brain/GI neoplasms Nitrosureas |
Antimetabolites | Folic Acid Analogue - Methotrexate |
Vinka alkaloids | Vinca rosea shrub |
Antibiotics | Products of Strep bacteria |
Interferons and Interleukins | Interferon alpha and interleukin-2 |
Specific Agents | Alkylating Agents, Antimetabolites, Vinka alkaloids, Antibiotics, Hormone agonists/antagonists,Enzymes Interferons and interleukins |
Oral Complications | Oral Mucositis, Salivary Gland Dysfunction, Neurotoxicity, Infection |
Oral Mucositis | Most frequent complaint, Inflammation/breakdown of oral mucosa, Erythema w/and w/o ulcerations, Direct damage of chemo drug, Emesis introduces harmful acid to mucosa, Normal physical trauma to compromised surface, Abnormal and slow healing |
Salivary Gland Dysfunction | Irreversible with radiation, reversible with chemo, Frequent saline rinses Saliva substitutes, Sugarless gum/candy, Sipping water constantly, Bethanecol, cevimeline, pilocarpine |
Neurotoxicity | Leads to severe, deep-seated throbbing pain that mimics dental pathology, Dysguesia - sense of taste changes, TMJ disorders may present due to sleep disruption, stress of tx, Eliminate actual dental problem, Palliative |
Infection | Immunosuppression and compromised mucosa leads to easier/more infections from normal flora and frequent candidal infections, OH, antibacterial rinses, prechemo preparations |
Immunotherapy Treatment Strategies | Augmenting - amplification of immune response(vaccines), Suppression - used in organ transplants, grafts or autoimmune diseases |
Cell Mediated Immunity | T-Cells ,mature in thymus, circulate around body, levamisole(Ergamisol)- used for colorectal cancers, Crohn's disease |
Humoral Immunity | B-Cells, bone marrow, fixed, replacement therapy(passive immunity) |
Immunosuppression | Most often used and most successful in organ/tissue transplants, cyclosporin(Restasis) - used in organ transplants and oral lichen planus, tacrolimus(Prograf) macrolide antibiotic-works like cyclosporin |
Immunosuppression | Glucocorticoids(prednisone or dexamethasone)-turns down immune system, cytotoxic drugs- kills lymphocytes/cell proliferation, cyclphosphamide(Cytoxan)-developed for cancer tx, used for autoimmune diseases, interferon beta 1b(Betaseron)-multiple sclerosis |
Innate Immunity | Non-specific actions like phagocytosis, stomach acid, chemicals in skin, carried out by cells like neutrophils and monocytes |
Acquired Immunity | Specific immunity alerted by antigens, carried out by B lymphocytes and T lymphocytes |
Cytokines | Secreted by T cells,autocoids that stimulate the immune response, activate many defense cells, and promote the inflammatory response |
Complement System | Collection of 20 proteins activated by antigen/antibody complex, increases inflammatory response |
Immunization | Forced acquired immunity by exposing pt to an antigen(inject dead organism, inject chemically treated toxins, inject live organism that have been attenuated) |
Passive Immunity | Short term(2-3 wks), infusing antibodies and/or activated T cells from the blood of another person or animal that has immunity |
