Arthropathy Flashcards
Gram positive/negative (choose) aerobes/anaerobes (choose) are most likely to be cultured from a polyarthritic joint.
(Gram positive aerobes but it can be a lot of things so culturing is important)
Leishmania associated polyarthritis is typically erosive/non-erosive.
(Erosive)
What occurs in joints affected with erosive polyarthritis?
(Boney lysis and destruction of joint ligaments → leads to joint instability and luxation)
What breed is associated with erosive polyarthritis?
(Greyhounds, particularly young animals are affected)
What joints are most commonly affected with type I IMPA?
(Small, distal joints)
What are some of the clinical signs that can be seen with type I IMPA?
(Cyclic fevers, stiffness, lameness, multiple joints involved, palpable joint effusion, cervical/vertebral pain, and inflammatory protein pattern)
How is IMPA diagnosed?
(By excluding all other causes of polyarthritis)
What cytology and culture results do you expect to get from an arthrocentesis of the joints of a dog with IMPA?
(Cytology → increased TNCC, non-degenerate neutrophils predominate; culture → negative)
(T/F) Septic arthritis more commonly only affects one joint.
(T, hematogenous spread is possible but not as common)
What is the minimum duration prednisone therapy should last in a dog with IMPA?
(4 months, taper should be slow)
How many of the following proposed criteria for diagnosis of systemic lupus erythematosus need to be true to say a patient has SLE?
- Abnormal ANA titer
- Cutaneous lesions
- Oral ulcers
- Arthritis
- Renal disorders (spec. Glomerulonephritis or persistent proteinuria)
- Anemia and/or thrombocytopenia
- Leukopenia
- Polymyositis or myocarditis
- Serositis
- Neurological disorders
- Antiphospholipid antibodies
(Either 2 things on the list and a positive ANA titer OR 3 or more of these things regardless of the ANA result; also I considered making this a “list all of the options blah blah” but I’m feeling lenient)
