1
Q

What is the typical presentation of equine Cushings (PPID?)

A

Retained winter coat, weight loss, lame, PUPD

2
Q

What diagnositic tests can be used to diagnose PPID?

A

TRH stimulation test or basal ACTH test.

3
Q

What does PPID stand for and why is it referred to as this in horses? What is the condition in dogs/cats?

A

Pituitary Pars Intermedia Dysfunction becasue it is a pituitary based condition due to loss of DA inhibition from hypothalamic neurons.
In cats/dogs = Hyperadrenocorticism due to adrenal pathology

4
Q

What resiratory condition is common in older yorkies? How may this be diagnosed? Treatment?

A

Tracheal collapse due to degeneration of the tracheal cartilages (bronchomalasia)
Possibly diagnosed by radiographs BUT dynamic process so may require fluoroscopy
Treatment = minimising coughing rather than fixing problem
Obesity often contributing factor

5
Q

What pattern will be seen on radiographs with CHF?

A

Intersistial/alveolar pattern

6
Q

How is the bronchial pattern on a radiograph described? When would this be seen?
What diagnostics may be carried out following this?

A

Tramlines and donuts
Bronchitis
BAL

7
Q

What is a sinus arrhythmia? Is it normal?

A

NORMAL!

Normal variation in heart rate with breathing pattern leading to regularly irregular beating and differences in P waves

8
Q

Define collapse

A

Unintentional prostration due to pathological mechanisms

9
Q

How may an arryhtmia be detected wrt pulse? What pathological state may be noted when examining pulse and when does this occour?

A

Pulse not synchronous with heart beat
Pulsus paradoxicalis occours when heart beats can be heard in the thorax but not felt as a radial etc. pulse. This is due to a sever decrease in blood pressure during inspiration, much greater than that which is normally experienced. This is seen in cardiac tamponade

10
Q

What are the 5 possible causes of shock?

A

Vasomotor failure (eg. anaphylaxis, sepsis)
Hypovoleamia
Metabolic (eg. O2, glucose)
Cardiac Failure
Obstructive disease (eg. pericardial effusion, volvulus

11
Q

Will PCV show aneamia due to heamorrage?

A

No, remining blood can still have the same PCV
