This issue of the MEDS newsletter
marks exactly 2 years that the
MEDS truck has been cruising the
streets of North-central Florida.
How time flies! I would like to
extend a special thanks to all of
you that have made MEDS what
it is today and I look forward to
seeing you in 2007.
Happy Holidays to all!
Proximal Pharyngitis and Epiglottitis
in a Yearling Filly
Student Case Study #1
By: Lynda Miller, Class of 2008
A yearling thoroughbred filly presented to the referring veterinarian on
emergency for having been kicked and pushed into the fence. The filly had
epistaxsis and labored breathing. Since presentation, the filly showed interest in
food, but was unwilling to eat. When she did attempt to eat, she would cough.
Upon presentation to the
MEDS service, the filly was
bright, alert, and responsive.
She had a heart rate of 40 beats
per minute, a respiratory rate
of 32 breaths per minute, and
a body temperature of 100.5 F.
Her mucous membranes were
moist and pink with a capillary
refill time of less than two
seconds. Auscultation of her
thorax was normal.
Endoscopic examination of
Lateral radiograph of the pharynx the upper airways revealed

arytenoids hyperplasia, an ulceration of the
tip of the epiglottis, ulceration
of the dorsal pharynx at entry into the esophagus, and dorsal displacement of
the soft palate occurring during the examination at which time the characteristic
gurgling noise was noted. Endoscopic examination of the esophagus revealed
a normal esophagus. Radiographs of the pharyngeal region revealed a gas
lucency surrounding the dorsal
area of the arytenoids, which UNIVERSITY

The filly was diagnosed with proximal pharyngitis and
epiglottitis with dorsal displacement of the soft palate.
The treatment for this filly was: use of a throat wash to
numb the area, stall rest, minimize hay consumption
and attempt to feed a mash diet, Tucoprim for a total of
14 days, the option of using Sucralfate for 48 hours was
left open for consideration at a later date.
It was recommended that a follow-up endoscopy be
performed after two to three weeks to recheck the

A 4 year old Quarter Horse filly was evaluated for abnormal gait following regular exercise. The problem had been
intermittent since the horse's purchase by a new owner 1 year ago. The filly responded well to pasture rest and oral
Phenylbutazone, but would show the same signs whenever she was ridden regularly, so an acceptable fitness level was
not attainable. A thorough lameness exam did not reveal any obvious cause of the problem. The filly was not lame, but
did show a shortened stride in the right hind. She would also drag the right toe consistently when longed to the right.
The owner reported that the filly may have had a stifle injury or disorder prior to her purchase. Given the history and
lameness exam findings, it was decided to pursue radiographs of the right stifle first.
Radiographs of the right stifle showed an area of decreased bone density within the medial condyle of the right femur
(the upper bone of the stifle joint). The lesion was close to the joint cartilage, with incongruence in the subchondral bone
immediately adjacent to the lesion. There were also arthritic changes on the medial tibia (the lower bone of the stifle
joint). A radiograph of the left stifle was taken so that left and right could be compared. The two stifles were markedly
different, with no significant abnormalities in the left stifle.
Osseous cyst-like lesions are most commonly diagnosed in the stifle, fetlock, pastern, coffin, and elbow joints. There
is still debate as to whether these changes are caused by trauma, by a developmental defect, or a combination of both.
They can be treated medically (intraarticular medications and systemic joint therapy) or surgically. The decision of how
to treat the disease depends on which joint is involved, whether there is secondary joint disease (such as osteoarthritis or
osteochondritis dessicans), and the age of the horse.
Above: Lateral oblique and craniocaudal radiographs of the right stifle show the
osseous cyst-like lesion with the medial condyle of the femur as well as osteoarthritis
of the medial tibial plateau.

Two months ago, the MEDS program and the team of veterinarians at Surgi-Care Center for Horses in
Brandon, Florida decided that it would be a great idea to have the MEDS unit visit Surgi-Care Center
for Horses every Monday and provide a consistent internal medicine referral service. Since then, the
number of cases has increased weekly and the relationship between MEDS and Surgi-Care has resulted
in a great team.
