Elisangela P. Freitas, Sheila C. Rahal, Carlos R. Teixeira, Jorge V.L. Silva, Pedro Y. Noritomi, Carlos H.S. Villela, Seizo Yamashita

Abstract — An approximately 9-month-old fox (Pseudalopex vetulus) was presented with malocclusion and deviation of the lower jaw to the right side. Orthodontic treatment was performed using the inclined plane technique. Virtual 3D models and prototypes of the head were based on computed tomography (CT) image data to assist in diagnosis and treatment.

Naturally acquired feline immunodeficiency virus (FIV) infection in cats from western Canada: Prevalence, disease associations, and survival analysis
Madhu Ravi, Gary A. Wobeser, Susan M. Taylor, Marion L. Jackson

Abstract — This retrospective study evaluated epidemiologic features and disease associations of feline immunodeficiency virus (FIV) infection in client owned cats from western Canada. Among 1205 cats that were tested 66 (5.5%) were positive for FIV antibody (FIV+) with a higher prevalence in males than females. FIV+ cats were older than the overall population. Epidemiologic features and disease associations were compared between 58 FIV+, but feline leukemia virus negative (FeLV-) cats and 58 age and sex matched FIV-negative (FIV-), FeLV- cats. FIV positivity was associated with a history of bite wounds, increasing age, and male gender. Lethargy and oral diseases were significantly associated with FIV positivity. Although several FIV+ cats were euthanized, the survival time of FIV+ cats after diagnosis was not significantly different from that of FIV- cats. In summary, FIV prevalence was low in cats from western Canada, clinical signs/diseases were mild, and lifespan was not different in FIV+ cats.

Excessive sulfate and poor water quality as a cause of sudden deaths and an outbreak of diarrhea in horses
Brandy A. Burgess, Katharina L. Lohmann, Barry R. Blakley

Abstract — Sudden deaths and an outbreak of diarrhea in horses occurred in southern Saskatchewan in 2006. Five horses died while survivors presented with diarrhea and, in 1 case, acute neurologic signs attributed to hyponatremia. Diagnostic testing of affected horses and environmental testing suggested poor water quality, specifically high salinity and high sulfate concentration as the cause.

Reduction in pain response by combined use of local lidocaine anesthesia and systemic ketoprofen in dairy calves dehorned by heat cauterization
Todd F. Duffield, Anneliese Heinrich, Suzanne T. Millman, Andrew DeHaan, Shelley James, Kerry Lissemore

Abstract — This study assessed the efficacy of ketoprofen for mitigating pain following dehorning with an electric cautery iron. Forty Holstein heifer calves, 4 to 8 wk of age, were randomized to receive a lidocaine cornual nerve block and either an injection of ketoprofen (3 mg/kg IM) or physiological saline, 10 min prior to dehorning. Cortisol was measured from serum obtained 10 min prior to dehorning and at 3 and 6 h post-dehorning. Calf behavior was video-recorded between 0 to 2, 3 to 5, and 6 to 8 h post-dehorning, and frequency of ear flicks, head shakes, head rubs, lying, standing, feeding, and grooming were recorded. Finally, 24-h intake of calf starter was recorded. There was no effect of treatment on cortisol (P > 0.1); however, ketoprofen-treated calves displayed less ear-flicks and total head behavior (P < 0.05), and tended to consume more starter (P = 0.09) than control calves. Ketoprofen is effective for mitigating behavioral effects of postsurgical pain following dehorning in 4- to 8-week-old calves.

Kinematic characteristics of myositis ossificans of the semimembranosus muscle in a dog
José M. Vilar, Gustavo Ramirez, Giuseppe Spinella, Alfonso Martinez

Abstract — A 6-year-old Doberman pinscher dog was presented with myositis ossificans of the semimembranosus muscle. Linear, temporal, and angular kinematic patterns were recorded and compared with those of sound dogs of the same breed. The results indicate that the specific gait compensations occurring with this disease may aid in the diagnosis of myositis ossificans of the caudal thigh muscles.

Clinical outcome in dogs with nasal tumors treated with intensity-modulated radiation therapy
David W. Hunley, G. Neal Mauldin, Keijiro Shiomitsu, Glenna E. Mauldin

Abstract — Intensity-modulated radiation therapy (IMRT) is a valuable tool in human radiation oncology, but information on its use in veterinary medicine is lacking. In this study, 12 dogs with nasal tumors were treated with IMRT at a median radiation dose of 54 Gy. Patient survival times and frequency and severity of side effects on ocular structures, oral mucosa, and skin were recorded. Eight dogs (67%) had resolution of clinical signs during radiation therapy. Median overall survival time was 446 d with a 50% 1-year and a 25% 2-year survival rate. Minimal grade 2 or 3 acute skin toxicity, no grade 2 or 3 late skin toxicity, and no grade 2 or 3 toxicity to oral mucosa or the eye opposite the tumor were identified in the dogs treated with IMRT in this study. The ipsilateral eye could not be routinely spared due to its proximity to the tumor.

Asymmetric lumbosacral transitional vertebra and subsequent disc protrusion in a cocker spaniel
Rebecca Archer, Thomas Sissener, Neil Connery, Tim Spotswood

Abstract — A 10-year-old cocker spaniel bitch presented with severe lumbosacral pain and acute onset left pelvic limb lameness. A diagnosis of asymmetric lumbosacral transitional vertebra with disc protrusion at L6-L7 was made by computed tomography. The cauda equina and left L6 nerve root were surgically decompressed with a dorsal laminectomy and lateral foraminotomy, which led to rapid resolution of the clinical signs.

Accidental epidural injection of thiopental in a dog
Allison L. O’Kell, Barbara Ambros

Abstract — A 3-year-old Labrador retriever was presented to the Western College of Veterinary Medicine for a tibial plateau levelling osteotomy. While performing a pre-operative epidural, thiopental was inadvertently administered into the epidural space. Treatment included epidural saline flushing and intravenous methylprednisolone sodium succinate. No neurologic deficits were detected.

Abstract — This article describes the clinical and pathological features of an orphan 7-day-old, male Formosan sambar fawn that was hospitalized for treatment of weakness. The fawn had been deprived of colostrum and developed suppurative meningitis that was attributed to Escherichia coli.
