73
Q

T/F: On CT, If you observe destruction of the nasal septum, frontal sinuses or cribriform plate, or extension of disease into the nasopharynx or periorbital region, this animal likely has lymphoplasmacytic rhinitis

A

False Destruction of the nasal septum, frontal sinuses or cribriform plate, or extension of disease into the nasopharynx or periorbital region are not expected with LPR and should prompt investigation into the presence of fungal rhinitis or neoplastic disease Given that it is an idiopathic disease, the lack of specific findings is important. Dogs should have no funduscopic lesions, no lymphadenopathy, no facial or palate deformities, and healthy teeth and gums, etc.

74

A

Sneezing, reverse sneezing

75
Q

What is the hallmark sign associated with feline herpesvirus

A

right middle lung lobe although other lungs can be affected

78
Q

What fluid characteristics would you expect to see associated with a pleural effusion caused by hemorrhage (bleeding masses, coagulopathies, trauma)?

A

These effusions are red, often contain protein & cell concentrations compatible with peripheral blood The composition of a hemorrhagic effusion will change with time: As cells are phagocytized & degraded, the number of RBCs will decrease.

79

In the case of collapsing trachea, corticosteroids as a single dose can be given to decrease tracheal inflammation. What drug is recommended?

A

dexamethasone Dexamethasone lasts ~48 hours and is ~7x more potent than prednisone

80
Q

A

~2-12 hours after trauma

81
Q

What fluid characteristics would you expect to see associated with a pleural effusion caused by lymphorrhagia?

Predominantly lymphocytic these effusions are lymphocyte predominant. As they become chronic or with repeated drainage inflammation occurs resulting in more neutrophils (non-degenerate) and macrophages. Chylous effusions contain chylomicrons and are classic “ milky” effusions

82
Q

Protein poor transudate in the pleural cavity is most frequently caused by?

A

Hypoalbuminemia

A

Influenza Type A H3N8 Because this is a rather newly emerging disease, almost all dogs, regardless of breed or age, are susceptible to infection and have no immunity. Virtually all dogs that are exposed to the virus become infected and nearly 80% show clinical signs of disease. Fortunately, most affected dogs have the mild form

84

Q

Upper respiratory or lower respiratory sign? nasal discharge

A

upper respiratory

87
Q

T/F: Canine Chronic Bronchitis is usually self-limiting and dogs recover within a year after initial signs

False canine chronic bronchitis is irreversible and progressive; incurable.

88
Q

What is the typical signalment associated with ciliary dyskinesia?

A

young purebred dog with recurrent respiratory tract infections/signs

89
Q

What is the mortality rate associated with cases of ALI/ARDS?

A

~100% There have been 2 reported cases that have survived

90
Q

What diagnostic modality provides us with a definitive diagnosis in the case of progressive interstitial fibrosis?

A

lung biopsy Lung aspirate is sometimes helpful & less invasive than lung biopsy

91
Q

protein-rich transudate in the pleural cavity is most frequenty caused by:

A

heart failure The lungs contain lymph that is higher in protein and thus fluid escaping from the capillary beds here has higher protein content.

92
Q

T/F: When performing thoracic radiographs to help diagnose pulmonary neoplasia, sixteen-thousand views should be taken

A

False Three views should suffice Thoracic radiography: Take right & left laterals & VD: 3 view “met check” Primary neoplasia:
 Usually focal single‐ or multiple‐mass lesions o lobar consolidation Diffuse pulmonary infiltrate can also be found Dog: Right caudal lobe more commonly affected Cat: Left caudal lobe more often involved Metastatic neoplasia
 Multiple, discrete, interstitial nodules of variable sizes or Diffuse interstitial pattern
 May find lymphadenopathy, pleural effusion Cat: Ill defined nodules or diffuse, patchy, mixed alveolar patterns

93
Q

T/F: In animals with pyothorax, antibiotics should be administered for 5-7 days and if the response to therapy is poor a chest drain should be inserted

A

False antibiotics should be given long-term (months)

94
Q

You would expect to hear crackles with which of the following diseases? Diaphragmatic hernia Pulmonary edema Pneumothorax Nasopharyngeal polyp Chylothorax

A

Pulmonary edema Animals with pulmonary edema are seen because of cough,tachypnea, respiratory distress, or signs of the inciting disease. Crackles are heard on auscultation, except in animals with mild or early disease. Blood-tinged froth may appear in the trachea, pharynx, or nares immediately preceding death from pulmonary edema.

95

143
Q

T/F: In general, you want to avoid cough suppressants if a dog has a moist, productive cough

A

Yep. Cough suppressants are used cautiously because cough is an important mechanism for clearing airway secretions. In some dogs, however, the cough is incessant and exhausting, or ineffective, because of marked tracheobronchomalacia and airway collapse. Cough suppressants can provide significant relief for such animals and may even facilitate ventilation and decrease anxiety.
