Q

True or false: dogs with a closed cervix pyometra are less sick.

A

False. Dogs with an open cervix pyometra aren’t as sick because they are getting some relief. Closed has more clinical signs because it is full of pus that can’t get out

Q

What diagnostics are used for pyometra?

A
Vaginal cytology
CBC
Chem panel
Rads and US
Culture
32
Q

If you had one diagnostic tool to use for pyometra, what would it be and why?

A

US

A pyometra will appear hyperechoic and will look like a snow globe

33
Q

What are the cytology findings with pyometra?

A

A lot of degenerative neutrophils

34
Q

What will show up in most cases on CBC?

A

A

Concurrent UTI with the same bacteria

36
Q

True or False: you would use cystocentesis for obtaining a urine sample in a dog with pyometra.

A

False. DO NOT USE CYSTOCENTESIS. Free catch is a better option.

37
Q

What is the best treatment for pyometra?

A

OHE

38
Q

What is the medical management for pyometra?

A

Select patients carefully. If extremely ill do not use. Only consider with valuable breeding animals and those with open cervix
Prostaglandins: 0.25 mg/kg/day, SQ, for 5 days starting with a lower dose
Supportive care
OHE once breeding career is finished

39
Q

What is ORS a complication of?

A

OHE

40
Q

Is ORS more common in cats or dogs?

A

Cats

41
Q

When does ORS occur?

A

When a piece of retained ovary becomes functional

42
Q

What are clinical signs of ORS?

A

Spayed female exhibiting signs of proestrus/estrus: vuvlar swelling, mucoid to serosanguious discharge, behavioral signs
Pseudocyesis

43
Q

What are the various conditions that cause blood vaginal dischatge in spayed females?

A
ORS
Vaginitis
Vaginal neoplasia
Stump pyometra
Trauma
Exogenous estrogen exposure
44
Q

What is the average interval from OHE to estrus?

A

Over 15 months

45
Q

What can be used for diagnosis of ORS?

A

Vaginal cytology
Vaginoscopy
Rads and US are usually not helpful
Hormone profile

46
Q

What is seen on vaginal cytology with ORS?

A

Consistent with proestrus or estrus in the absence of exogenous estrogen exposure
Predominant cornified/superficial cells

47
Q

What is seen with vaginoscopy with ORS?

A

Vaginal edema

48
Q

When is using US an exception for ORS?

A

Large breed dogs with large follicles or cysts present

49
Q

What hormones should be checked with ORS?

A

P4
LH
AMH

50
Q

When should P4 be measured when testing for ORS?

A

After estrus subsides (2 weeks later)

51
Q

What does the presence of P4 > 2 confirm?

A

The presence of luteal tissue

52
Q

What should be given to cats to test their P4 for ORS?

A

GnRH because they are induced ovulators

53
Q

How is the LH concentration used in diagnosing ORS?

A

Spayed females have a high LH, so if LH is low it is likely that the animal has ORS
You must be careful using this in a dog with potential ORS becuase they will still have an LH surge on one day, so test for a couple of days

54
Q

What is AMH produced by?

A

Sertoli cells and granulosa cells

55
Q

What do elevated AMH levels indicate?

A

Functional ovarian tissue

56
Q

What is the treatment of ORS?

A

Remove offending tissue surgically

Lifelong medical management with mibolerone (not recommended)

57
Q

What was canine brucellosis identified as a cause of if 1966?

A

Infertility and abortion

58
Q

Is brucellosis zoonotic?

A

Yes

59
Q

What states is brucellosis reportable in?

A

Georgia and Illinois

60
Q

What causative agents of brucellosis are reportable in MS?

A

Brucella abortus, suis, and melitensis

61
Q

What is the etiology of canine brucellosis?

A

Brucella canis is an obligate intracellular gram-negative coccobacillus
Natural infection restricted to canines

62
Q

What are the modes of transmission of canine brucellosis?

A

Ingestion of bacteria (most common)
Venereal transmission
AI
Vertical transmission

63
Q

What can be ingested that will contain the bacteria to cause brucellosis?

A

Placental tissue
Vaginal discharge
Mammary secretions

64
Q

How can AI cause brucellosis?

A

Most extenders with antibiotics have been found to be ineffective against B. canis

65
Q

How does vertical transmission cause brucellosis?

A

Congenital infection if pups are born alive and survive

Ingestion of milk from infected bitch

66
Q

What are the clinical signs of canine brucellosis?

A

Infertility (most common)
Most dogs show no or few
Prolonged bacteremia (1-2 years) without fever
Reproductive disorders in the bitch: abortion late in gestation (classic sign), early embryonic death, sero-purulent vaginal discharge
Reproductive disorders in the male: Prostatitis, Epididymitis, Scrotal dermatitis, Testicular degeneration, Orchitis is rare

PLN
67
Q

What tests can be used to diagnose canine brucellosis?

A
Serology
Rapid card agglutination test (RCAT)
