Derm2- Feline Pruritus

  1. What lesions of pruritus uniquely occur in cats? (3)
    non-inflammatory symmetric alopecia, miliary dermatitis, eosinophilic granuloma complex
  2. What lesions of pruritus are common in dogs but relatively uncommon in cats? (3)
    excoriations, lichenification, hyperpigmentation
  3. Feline cutaneous reaction patterns of pruritus. (4)
    feline symmeteric alopecia, miliary dermatitis, eosinophilic granuloma complex, head and neck pruritus
  4. What is the first step to evaluating feline symmetric alopecia?
    trichogram [pluck hairs and look at root]: [blunted] self-induced--> pruritic (common), psychogenic (uncommon) VERSUS [pointed] non-self-induced
  5. Describe miliary dermatitis. (4)
    papulocrustous (papules and crusts) cutaneous reaction pattern, secondary alopecia, erythema, excoriation
  6. What are the 3 components of eosinophilic granuloma complex?
    indolent ulcer, collagenolytic granuloma, eosinophilic plaque
  7. Describe the indolent ulcer that occurs with eosinophilic granuloma complex. (5)
    upper lip, well-circumscribed, disc-shaped, no pain or pruritus
  8. What are the 4 types of collagenolytic granuloma?
    linear granuloma, pharyngeal granuloma, chin form, footpad
  9. 3 general categories of pruritic feline dermatoses.
    allergic, parasitic, infectious
  10. What allergies do cats get that cause pruritus? (3)
    FAD, atopic dermatitis, CAFR
  11. What parasitic diseases of cats are pruritic? (4)
    Notoedres (sarcoptic mange), Demodex gatoi, +/- Demodex cati, Cheyletiella
  12. What is the very first step of the treatment plan for a pruritic cat?
  13. After the initial flea treatment, what should you do at the 4 week recheck?
    • Good response--> Dx FAD
    • Poor response--> if nonseasonal, initiate food trial; if seasonal, atopic dermatitis
  14. What should you do at the 8 and 12 week rechecks?
    • Good response to food challenge--> rechallenge with original food--> if pruritus recurs, Dx CAFR
    • Partial or poor response to food trial--> atopic dermatitis or atopic AND CAFR
  15. What are steroid options for control of pruritus in cats? (3)
    prednisolone, dexamethasone, depo-medrol
  16. What non-steroidal medications can be given to cats to control pruritus?
    Atopica- MINIMUM 4 week trial
  17. What must you be sure of before starting a cat on Atopica? (2)
    FeLV/FIV negative, no history of cancer
  18. What are additional anti-pruritics for cats that are not as commonly used?
    antihistamines, essential fatty acids, topical anti-pruritics (bathing and topicals are more difficult in cats than dogs; think about E collar until dried)
  19. How do you diagnose psychogenic self-induced alopecia?
    always assume self-induced alopecia is pruritic in origin--> if you treat as FED, CAFR, and atopic and if still doesn't respond--> Dx psychogenic alopecia
  20. How can you handle psychogenic alopecia in cats? (3)
    behavioral modification, drug therapy, refer to veterinary behaviorist
  21. You do a trichogram, there is no barbering of hair; the ends of hairs are pointed...what do you do?
    Non-self-induced alopecia (very rare): endocrine, paraneoplastic
  22. What are endocrine causes of non-self-induced alopecia? (3)
    hyperthyroidism, DM, hyperadrenocorticism
  23. What paraneoplastic disorders cause non-self-induced alopecia in cats?
    • feline paraneoplastic alopecia: pancreatic adenocarcinoma, biliary carcinoma
    • feline thymoma-associated exfoliation dermatitis
