Bilateral exophthalmos in a Holstein cow with lymphosarcoma - Malatestinic, Andrea
A 4-year-old Holstein cow presented with severe bilateral exophthalmos. A complete blood cell count revealed late stage lymphoma; the agar gel immunodiffusion test for enzootic bovine leukosis was positive. The cow was euthanized 1 wk after presentation. Necropsy revealed generalized lymphadenopathy and tumors in most organs. Final diagnosis was lymphosarcoma.
Vaccine-associated fibrosarcoma in a cat - Martin, Melanie
An 8-year-old, spayed, female domestic shorthair was diagnosed with a vaccine- associated fibrosarcoma and treated with full course radiation therapy, aggressive surgery, and postoperative chemotherapy. Histopathologic examination confirmed that excision of the tumor was complete. The cat was doing well 278 days after initial presentation.
Cerebellar abiotrophy in a miniature schnauzer - Berry, Michelle L.; Blas-Machado, Uriel
A 3.5-month-old miniature schnauzer was presented for signs of progressive cerebellar ataxia. Necropsy revealed cerebellar abiotrophy. This is the first reported case of cerebellar abiotrophy in a purebred miniature schnauzer.
Relationship between group A porcine rotavirus and management practices in swine herds in Ontario - Dewey, Cate; Carman, Susy; Pasma, Tim; Josephson, Gaylan; McEwen, Beverly
A case-control epidemiological study was conducted to determine whether an increased diagnostic rate for group A rotavirus in swine herds in Ontario was associated with specific management factors. The number of new herds tested per year and the proportion of new positive herds increased between 1994 and 1997. Herd size was larger and weaning age was younger in rotavirus-positive herds compared with rotavirus-negative herds. Pigs raised in all-in all-out nurseries were 3.4 times more likely to have a positive group A rotavirus diagnosis than pigs in continuous flow facilities. This study demonstrates that the changes seen in group A rotavirus...
An evaluation of the analgesic effects of meloxicam in addition to epidural morphine/mepivacaine in dogs undergoing cranial cruciate ligament repair - Fowler, David; Isakow, Kevin; Caulkett, Nigel; Waldner, Cheryl
The analgesic efficacy of an epidural morphine/mepivacaine combination alone versus epidural morphine/mepivacaine in combination with meloxicam administered prior to the onset of anesthesia was assessed in 20 dogs undergoing cranial cruciate ligament repair. Numerical and visual analog pain scores were performed prior to anesthesia and at 6, 8, 12, 16, and 24 hours after epidural administration by a trained observer, blinded to treatment. An analgesiometer was used to determine the amount of pressure required to produce an avoidance response at the incision site. Animals that received meloxicam demonstrated a trend toward decreased pain scores over all time periods. Visual analog...
