Q

What is the drug of choice for treatment of histiocytic ulcerative colitis?

A

enrofloxacin

Since histiocytic ulcerative colitis is a bacterial infection, it is antibiotic responsive. Enrofloxacin is typically effective. It is critical to treat for at least 8 weeks (even if the patient feels normal by week 2). Stopping antibiotics before 8 weeks has been associated with recurrence of infection and resistance to enrofloxacin.

Q

What liver disease is associated with the highest mortality rate in cats?

A

hepatic lipidosis

Lipid accumulation in hepatocytes​ eventually results in loss of hepatic function.

Q

Maggie, a 6-year-old, FS Shih Tzu, visits your practice for a routine health screen. She has been diagnosed with idiopathic epilepsy and is on phenobarb. She is otherwise healthy. Biochemistry detects 10 x TN ALKP, 8 x TN ALT. Which is the correct statement?

  • This is enzyme induction from phenobarbitone
  • The liver enzymes are prognostic of phenobarb damage
  • Recommend liver function testing and US/biopsy
  • Immediately discontinue phenobarb
A

Recommend liver function testing and US/biopsy

We know that phenobarbitone can be responsible for enzyme induction (specifically ALKP), but this is allowable within a certain range. Generally if ALKP is less than 5x normal, it is simple induction. However, if the enzymes are significantly elevated (as in this example), you must consider that there is phenobarbitone toxicity

60

A

T. foetus

67
Q

What is the most important component of treatment in a cat with hepatic lipidosis?

Q

A 7-year-old M/N German Shepherd presents to you with a history of painful defecation. On physical exam, you note these lesions.

What is your diagnosis?

A

Perianal fistulas

78
Q

T/F: For the diagnosis of congenital PSS, fasting and postprandial serum bile acid level determinations are recommended to enhance detection ability

A

True

this is because it is relatively common for fasting values to be well within normal limits and for postprandial values to be as high as 10- to 20-fold higher than normal postprandial values.​

79
Q

When submitting a liver biopsy, what special stain would you request if you want to confirm copper accumulation?

A

rhodanine

80
Q

What is the most sensitive diagnostic test for acute pancreatitis in dogs?

Pseudocyst​

A pancreatic pseudocyst is a collection of fluid containing pancreatic enzymes and debris in a nonepithelialized sac. Pseudocysts have been recognized in association with pancreatitis in cats and dogs, although they appear to be rare

83
Q

Name the three disease entities involved with feline triaditis:

A

pancreatitis, cholangiohepatitis, and inflammatory bowel disease (IBD)

84
Q

T/F: Elevated amylase and lipase are diagnostic for pancreatitis in the dog

A

False

Elevated amylase and lipase are compatible with pancreatitis in the dog but are not diagnostic or pathognomonic since they can be elevated with gastrointestinal or liver disease or azotemia. And dogs with normal amylase and lipase values may have pancreatitis.

**Amylase and lipase are of no value in the cat**

85

88
Q

Bobby is referred to your clinic for further investigation of liver disease. He is weak, with non-specific signs of pain. Biochemistry shows ALP (2 x TN), AST (4 x TN). What should you also test?
