Respiratory Disease Flashcards
Disease of the URT (upper respiratory tract)
Rhinits, Nasal tumors, epistaxis, sinusitis, tonsillitis, laryngitis
Dx of rhinitis
clinical signs, culture and sensitivity
Clinical signs of nasal tumors
unilateral nasal discharge (may be hemorrhagic or mucoid)
Dx of nasal tumors
Rads, CT, Endoscopy, Bx for Definitive dx
Etiology of epistaxis
trauma, foreign objects, tumors, bleeding disorders
What is epistaxis
nose bleed
Tx of epistaxis
ID the cause, stop bleeding by instilling epinephrine/lidocaine to the area
Etiology of sinusitis
tooth-root abscess most commonly, foreign body pentration
Clinical signs of sinusitis
swelling under the eye, unilateral nasal discharge
Dx of sinusitis
PE, Rads, C&S
Tx of sinusitis
antibiotics based on C&S, removal of affected tooth, draining of fistulas
Etiology of tonsillitis
infectious agents from the URT
Clinical signs of tonsillitis
increased swallowing, anorexia, salivation
Dx of tonsillitis
oral and upper airway exam
Etiology of laryngitis
excessive barking, howling most commonly, infection can occur
Clinical signs of laryngitis
changes to the voice
Tx of laryngitis
restrict barking, anti-inflammatory drugs, antibiotics if indicated
Clinical signs for laryngeal paralysis
Dogs: harshness in their panting, increased panting or panting when cool and calm a horse or raspy sounding bark
Horse:abnormal noises heard when horse breathes in during faster levels of exercise
Tx of laryngeal paralysis
medical care during breathing crisis: oxygen therapy, external cooling, sedation, intubation
sx: unilateral arytenoid lateralization or “tieback” surgery
Etiology of tracheal collapse
idiopathic
Signalment for tracheal collapse
Pomeranians, yorkshire terriers, toy-breeds
Clinical signs of tracheal collapse
“goose-honk” cough
Dx of tracheal collapse
rads and fluoroscopy
What is feline asthma
obstructive and allergic respiratory diseases, sometimes called asthma, bronchitis, or bronchial asthma
Etiology of feline asthma
chronic airway inflammation, inhaled irritants, may be secondary to allergies/parasites
Clinical signs of feline asthma
coughing, wheezing, labored breathing
Clinical signs of feline hw disease
cough, dyspnea, hemoptysis, sudden death
What is pleural effusion
buildup of fluid within pleural space, leading to respiratory distress
Pleural effusion
transudate/modified, Transudate/exudate
Hemothorax
hemorrhagic effusion
Pyothorax
purulent exudative effusion
Chlyothorax
“chyle” is lymphatic fluid, contains a lot of fat
Etiology of pleural effusion
neoplasia, congestive heart failure, hemorrhage, infection
Clinical signs of pleural effusion
dyspnea, cough, pleural pain
Etiology of Chronic obstructive Pulmonary disease “heaves” in horses
dry/dusty environment
clinical signs for “heaves” in equine
increased respiratory effort upon EXPIRATION, “heave line”, cough, nostril flare at rest
Tx of heaves in equine
soak hay, change environment, antihistamines, steroids, bronchodilators
Etiology of Exercise-induced pulmonary hemorrhage (EIPH) “bleeders”
idiopathic (increased CO and vascular blood pressure lead to rupture of the capillaries in the lungs)
Clinical signs of EIPH
epistaxis, decreased performance, dyspnea, respiratory distress
Signalment of EIPH
racehorses (thoroughbreds, quarter horses, Standardbreds)
Etiology of foal pneumonia
rhodococcus equi
Sources of transmission for foal pneumonia
affected soil (contaminated with manure)
Clinical signs of foal pneumonia
cough, dyspnea, fever, anorexia, diarrhea
What is equine influenza
a highly contagious viral disease that spreads rapidly among naive horses
Etiology of equine influenza
viral: orthomyxovirus A/equine-2
Transmission of equine influenza
inhalation of respiratory secretions
Etiology of Equine viral rhinopneumonitis aka herpes
EHV-1 and EHV-4
Clinical signs for equine viral rhinopneumonitis (herpes)
serous nasal discharge, malaise, pharyngitis, cough, inappetence, submandibular or retropharyngeal lymphadenopathy, secondary bacterial infections
Signalment of pasteurellosis
sheep and goats
Etiology of pasteurellosis
pasteurella hemolytica
Clinical signs of pasteurellosis
nasal discharge, fever, anorexia, weight loss
Etiology of contagious caprine pleuropneumonia
mycoplasma capricola
clinical signs of contagious caprine pleuropneumonia
fever, anorexia, death within 2 days
Tx of contagious caprine pleuropneumonia
tylosin, tetracycline
Etiology of ovine progressive pneumonia (OPP)
lentivirus
Transmission of ovine progressive pneumonia (OPP)
ingestion of milk from infected animals
Clinical signs of ovine progressive pneumonia
progressive malaise/emaciation/dyspnea/cough
Dx for ovine progressive pneumonia
ELISA test for virus
What is oestrus ovis
deposited fly larvae around the nostrils
clinical signs of oestrus ovis
sneezing, nasal discharge, rubbing of the nose, rhinitis/sinusitis
Tx of oestrus ovis
ivermectin
Bovine respiratori disease complex (BRD) develops as a result of
complex interactions between environmental factors, host factors, and pathogens
