Damage to the left recurrent laryngeal nerve is associated with "roaring" in
horses. The left recurrent laryngeal nerve is a branch off of which cranial
nerve?
A - Glossopharyngeal (CN 9)
B - Facial (CN 7)
C - Trigeminal (CN 5)
D - Hypoglossal (CN 12)
E - Vagus (CN 10)
E
Damage to the recurrent laryngeal nerve (a branch of the Vagus (CN 10))
causes laryngeal hemiplegia - a paralysis of the abductor muscle (dorsal
cricoarytenoid muscle) controlling the glottic cleft in the larynx.
This allows the vocal fold (usually left side) to evert into the lumen of the
larynx, obstructing airflow, leading to a roaring sound, and most
importantly, slowing the horse.
,Oral administration of which of these drugs has been implicated as a cause
of esophageal strictures in cats?
A - Doxycycline
B - Azithromycin
C - Diazepam
D - Potassium bromide
A
The correct answer is doxycycline. There is also evidence that clindamycin
can cause stricture formation. For this reason, it is recommended that after
pilling a cat with doxycycline, it is followed with a small volume (5-10 mls) of
water.
,A 5 year old female spayed Cocker Spaniel is presented with a strange
expression. Her right ear and lip appear to droop. There is ptosis O.D. (right eye)
and the dog is drooling on the exam table. What anatomic structure is damaged?
A - Right side inner ear
B - Left side inner ear
C - Trigeminal nerve
D - Facial nerve
E - Left side medulla, motor tract
D
Think of facial nerve paralysis (CN 7) with a unilaterally droopy face.
Remember the facial nerve is motor to the muscles of facial expression
(explaining the right side drooped ear, lip and eyelid) and innervates the lacrimal
and salivary glands. Loss of innervations can lead to a dry eye, and possibly to
exposure keratitis if animal losses ability to close eyelid from damage to facial
nerve innervation of the orbicularis oculi muscle.
Idiopathic in 75% of canine cases (25% of cats).
Can also see these signs with middle ear damage (from otitis media), from facial
nerve trauma (ear surgery in dogs, or pressure from halter buckles in
anesthetized horse), or neoplasia.
Think more of a dropped jaw with trigeminal nerve neuropathy (CN 5-dogs,
horses).
, You see an 8-month old kitten with the effusive form of feline infectious
peritonitis and perform euthanasia. The kitten was having severe diarrhea
around the house when it became ill. The owner has a 2 year old cat at home
and wants to know what this cat's prognosis is since it has been exposed to the
sick kitten. Currently this cat is clinically healthy. What do you tell her?
A - You recommend a coronavirus titer to determine it the cat is actively infected
B - Her other cat may develop symptoms within the next two weeks because FIP
is highly contagious
C - Feline infectious peritonitis is not contagious and because her other cat
died of FIP does not mean this cat will succumb to the disease
D - Place the cat on L-lysine to prevent or suppress any infection with FIP
E - Perform a PCR on the cat's feces to see if the virus is being shed
C
Feline infectious peritonitis is not a contagious disease. It is a disease that is
caused by a mutation of feline enteric coronavirus. It is unknown why in some
patients this virus mutates and causes the FIP syndrome. It is most likely to occur
in young or immunocompromised cats. Her other cat is not necessarily going to
get FIP just from exposure. In fact, the majority of the cat population has been
exposed to the feline enteric coronavirus.
Because most cats in the general population have been exposed, it makes
interpretation of coronavirus titers difficult. The titers can be elevated due to prior
exposure and not from FIP. The titers can only be interpreted in lieu of clinical
signs, blood results, etc.
