Q

Why do you need to do a general physical exam?

A
  1. to rule out other body systems

2. to look for problems to support differentials

Q

What are two problems with gait evaluation?

A
  1. requires experience

2. need to reproduce the problem–it may not be apparent at a walk–can be subtle

  2. time consuming
  3. potentially dangerous
  4. difficult to interpret

  2. time consuming
  3. potentially dangerous

  5. need to know where you are looking
  6. need to have some idea what looking for
18
Q

What are 3 special tests that can be done?

A
  1. Biopsy (muscle, bone, joint)
  2. EMG
  3. Myasthenia gravis testing
  4. Genotyping
19
Q

What is signalment?

A
  1. species
  2. age
  3. breed
  4. sex
  5. activity
  6. environment
20
Q

Why is signalment important?

A

Some of the disease are very specific to the species, age, breed, sex, activity, environment

21
Q

Radiography is good for seeing what 4 things in bones?

A
  1. fractures
  2. density
  3. irregularity of growth
  4. can help with joints (but can’t see cartilage)
22
Q

What is ultrasound good for?

A
  1. soft tissue (tendon, joint capsule, abnormalities in muscle)
  2. can image surface of bone (e.g. pelvic fracture)
23
Q

What is CT good for?

A
  1. can get a 3D image so can get a better view of complex lesions
  2. can see some soft tissue lesions
24
Q

What is MRI good for?

A
  1. very good for soft tissue
  2. can image cartilage
  3. limited use for bone
25
Q

What is scintigraphy and what can it be used for?

A
  1. dynamic imaging

2. can be used to look for lesions in soft tissue and bone

26
Q

What are problems with scintigraphy?

A
  1. have to give a radioactive
27
Q

What are problems with scintigraphy?

A
  1. have to give a radioactive compound and that goes into urine and stall
  2. usually doesn’t help much?
28
Q

What is scintigraphy mostly used for?

A

spine lesions in horses (kissing spines)

29
Q

What is arthrocentesis and what can it diagnose?

A

sample synovial fluid of joint. Can diagnose inflammation (potentially infeciton, can help ID cause of inflammation)–however remember fluid is often negative for bacteria b/c in synovial membrane

30
Q

What are the advantages and disadvantages of muscle biopsy?

A

advantages

  1. relatively easy to do
  2. many options beyond simple histopath

disadvantages

  1. samples need to be handled carefully
  2. may need specialized lab services
31
Q

What are the advantages and disadvantages of bone biopsy?

A

advantages
1. can be a good tool for diagnosis

disadvantages

  1. need specialized tools (very specific needles)
  2. results delayed while sample is decalcificied
32
Q

What can EMG be used to do?

A
  1. generally more of a neurology test

2. can ID certain muscle disorders due to abnormal electrical activity (e.g. myotonia)

33
Q

What is an example of a muscle disorder that has a genetic basis?

A

Hyperkalemic periodic paralysis

34
Q

What does GIN AND TONIC stand for?

A 
G-genetic
I-infectious
N-non known cause
A-allergic/autoimmune
N-nutritional
D-degenerative
T-traumatic
O-oncologic
N-endocrine
I-intoxication
C-congenital
35
Q

What is a toxicology example that involves the musculoskeletal system?

A

monensin

36
Q

what are miconutrients that might be involved with muscle pathology?

A

Vit E and Se
