  1. It is the type of transplant done with one self

  4. A transplant between two different species.
    • Xenograft, considered Xenogenic
    • - Bovine grafts
  5. When it comes to the types of rejection of transplantation, this one can occur from days to weeks and it involves the primary activation of the T-cell response.
    Acute rejection
  6. When it comes to the types of rejection of transplantation, this one can occur from months to years after transplantation, probably occurs by continued cell medicated toxicity and under unclear causes...
    • Chronic rejection
    •  - This one creates a big problem because sometimes the causes are unclear
  7. When it comes to the types of rejection of transplantation, this one occurs minutes to hours after transplantation and is caused by performed anti-donor antibodies activation compliment.
    Hyperacute rejection
  8. Main complications of transplants...
    • Immunosupressive drugs can make host suceptable to infection and cause hepatoxicity and nephotoxicity (can also make prone to malignancies).
    • GVHD can cause a whole host of issues and some even affecting the GI tract, mucosal ulcerations make for opportunistic infections.
  9. Dental management of transplant patient...
    • - Should be coordinated with physician (medical consultation)
    • - Prior to transplant, acute oral infections must be managed to prevent complications
    • - Elective dental treatment can be done after transplantation
    • ** Always assess comorbidities, medicatons and labs, patients with end-organ damage
  10. Prior to transplant, the most important dental considerations...
    • Eliminate active dental disease and infection (extractions of non-restorable teeth, oral infections and prevention)
    • - Immunosuppresive drugs after transplant will debilitate the patients ability to fight infections.
  11. In an immediate post transplantation state or in post-transplantation chronic rejection state, what dental treatment can be done?
    No elective dental treatment and only emergency treatment, as non-invasive as possible.
  12. In a stable post-transplant period, how is the dental patient managed?
    • Check medications and side-effects (patients take a lot of immunosuppresants and steriods)
    • Consideraton for AB prophylaxis
    • Specific management needs based on the ogran type that was transplanted.
  13. What is the main oral side effect noticed in patients taking cyclosporine?
    • Gingival hyperplasia
    • - Dilantin (for sezures) can cause gingival hyperplasia as well
    • Cellcept can cause thrombocytopenia
    • (CCB also cause gingival hyperplasia but it is associated more with plaque accumulation)
    • Prednisone can cause opportunistic infections (it is a steroid) that is suppressing the immune system

    Limit epi to 2 carpules or less
  19. How do sulfonylureas work and what do they have a high risk of giving the patient?
    • Stimulate the beta-cells to create more insulin, this can cause a hypoglycemic event (in the case where the patient has not taken in enough calories).
    • Cannot work for type1 diabetes (because there are no beta cells in that type). These types of medications aren't used as much.
    • *Must keep glucose source available
  20. Biguanides (for diabetes) function is which way, and do they cause hypoglycemic events? Main side effect?
    • Biguanides (like, Glucophage), increase the insulin sensitivity in muscles and decrease production of glucose in the liver
    • This does NOT increase hypoglycemic events because there is not more glucose being produced in these medications.
    • Major side effect is taste disorder
  21. DPP-4 inhibitors in diabetics work with this function, and what is a major type?
    • These work to reduce glucagon and improve the A1C (without causing glycemia)
    • Januvia is a famous one now
  22. SGL2- inhibitors (for diabetes), function and which are the major types?
    • Inhibit the re-absorption of glucose in the kidney.
    • Invokana is a famous one with side effects like: dizziness, syncope, orthostatic hypotension, bone fracture and ketoacidosis
  23. As far as injectables for diabetes, the Incretin Mimmetics function in which way...
    • Increase insulin secretion

    • (Usually injected with a Pen)
    • Insulin is the other injectable, comes in short, intermediate, rapid onsets etc...
  24. In a patient whos A1C is above 9 and Blood glucose is above 200 what risks are there and what is done to prevent those? Especially if they have target end organ disease.
    • Risk of infection and poor wound healing post operatively
