  1. Evaluation of plasma inflammatory cytokine concentrations in racing sled dogs

    von Pfeil, Dirsko J. F.; Cummings, Bethany P.; Loftus, John P.; Levine, Corri B.; Mann, Sabine; Downey, Robert L.; Griffitts, Caroline; Wakshlag, Joseph J.
    In human athletes significant changes in cytokine concentrations secondary to exercise have been observed. This prospective study evaluated the effect of a multi-day stage sled dog race on plasma concentrations of monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor-alpha (TNF-α), interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-8 (IL-8), and interleukin-10 (IL-10). Samples from 20 dogs were harvested prior to and on days 2 and 8 of an 8-day race. Exercise resulted in significantly decreased TNF-α and IL-8 as well as increases of MCP-1, IL-6, and IL-10 concentrations (P-value between 0.01 and < 0.0001 for all parameters). The proportion of values for IL-2 that...

  2. Sialolithiasis in horses: A retrospective study of 25 cases (2002–2013)

    Carlson, Nicholas; Eastman, Tim; Winfield, Laramie
    This study evaluated outcomes of surgical treatment of equine sialolithiasis, highlighting cases involving the proximal parotid salivary duct. Sialoliths in the proximal parotid duct were difficult to identify radiographically and more frequently associated with draining tracts and sialadenitis compared with sialoliths in the distal parotid duct. Ultrasonography confirmed the diagnosis of sialolithiasis in all cases in which there was no radiographic evidence of a sialolith. All cases of proximal parotid duct sialolithiasis required transcutaneous removal. A longer duration of illness was observed in cases of proximal parotid duct sialolithiasis compared with cases involving the distal parotid duct, and in cases...

  4. Successful treatment of Solanum dulcamara intoxication in a Labrador retriever puppy

    Kees, Megan; Beckel, Nicole; Sharp, Claire
    A 10-week-old intact male Labrador retriever dog was presented for acute onset of weakness, ataxia, and generalized muscle tremors. The puppy was suffering respiratory and central nervous system (CNS) depression, was mildly pyrexic, and vomited plant material that was identified as creeping nightshade (Solanum dulcamara). He responded well to supportive care and was discharged successfully. To the authors’ knowledge, this is the first report of Solanum dulcamara toxicity occurring in a dog.

  6. Survey of western Canadian veterinary practices: A demographic profile

    Jelinski, Murray D.; Barth, Katrina K.
    A mixed-mode survey was used to describe the demographics of the veterinary profession in western Canada and to assess the demand for veterinary practitioners. Data were received from 655 practices (response rate = 52%), providing demographic data on 1636 individual practitioners. Most (60%) respondents self-classified their practices as exclusively small animal, while 25% and 4% were mixed animal or exclusively food animal practices, respectively. Across all practices, 77% of practitioners’ time was devoted to small animals and the average mixed animal practice devoted 60% of practitioners’ time to small animals. After accounting for practices that did not respond, there were ~300 full-time equivalent (FTE) vacant positions for veterinary associates; however,...

  8. Intraoperative acridine orange photodynamic therapy and cribriform electron-beam irradiation for canine intranasal tumors: A pilot study

    Maruo, Takuya; Nagata, Koichi; Fukuyama, Yasuhiro; Nemoto, Yuki; Kawarai, Shinpei; Fujita, Yukihiro; Nakayama, Tomohiro
    Untreated canine intranasal tumors carry a poor prognosis. We retrospectively evaluated the efficacy of marginal tumor resection in combination with intraoperative acridine orange (AO) photodynamic therapy (PDT) and 1 fraction of 5 Gy megavoltage irradiation for canine intranasal malignant tumors. When cribriform plate invasion or turbinate destruction around the cribriform plate was present, an additional fraction of 20 Gy was delivered with an electron beam during surgery. The study included 6 dogs, 2 of which were classified as stage I, 1 as stage II, and 3 as stage IV. The median local disease-free survival time and overall survival after the...

  9. Longitudinal evaluation of diagnostics in experimentally infected young calves during subclinical and clinical paratuberculosis

    Mortier, Rienske A.R.; Barkema, Herman W.; Orsel, Karin; Muench, Gregory P.; Bystrom, Janet M.; Illanes, Oscar; De Buck, Jeroen
    Five calves were inoculated orally at 2 weeks of age with a dose of 5 × 109 colony-forming units of Mycobacterium avium subspecies paratuberculosis (MAP) on 2 consecutive days. Two calves developed clinical Johne’s disease at 12 and 16 months of age after being consistently positive for MAP on fecal culture and antibody enzyme-linked immunosorbent assay (ELISA), starting 2 to 3 weeks and 4 to 5 months after inoculation, respectively.

  12. Cutaneous squamous cell carcinoma in an African pygmy hedgehog (Atelerix albiventris)

    Couture, Émilie L.; Langlois, Isabelle; Santamaria-Bouvier, Ariane; Benoit-Biancamano, Marie-Odile
    A cutaneous mass was surgically excised in a 4-year-old African pygmy hedgehog (Atelerix albiventris). A squamous cell carcinoma was diagnosed based on histopathological examination and local recurrence following excision is strongly suspected. To the authors’ knowledge, this is the first well-documented report of a cutaneous squamous cell carcinoma in this species.

  14. Bilateral renal T-cell lymphoma with hepatic infiltration and secondary polycythemia in a dog: Utility of cytology slides

    Froment, Rémi; Gara-Boivin, Carolyn
    This is a case of bilateral renal T-cell lymphoma associated with secondary erythrocytosis in a dog. This case is distinctive in using clonality combined with immunocytochemistry to support the diagnosis, thus emphasizing the utility of cytology slides when histology is unavailable. This combination may be a unique canine lymphoma entity.

  16. Acute idiopathic polyneuritis with spontaneous remission in an Abyssinian cat

    Jeandel, Aurélien; Matiasek, Kaspar; Blot, Stéphane
    An Abyssinian kitten was presented after a sudden onset of neurological disorders consistent with a polyneuropathy. Electrophysiological and histological investigations revealed an inflammatory polyneuropathy. No infectious agents were detected. Spontaneous recovery occurred rapidly without relapse (2 years follow-up). This is the first description of a histologically confirmed self-limiting feline polyneuritis.

  17. Dorsal midbrain syndrome associated with persistent neck extension: Clinical and diagnostic imaging findings in 2 dogs

    Canal, Sara; Baroni, Massimo; Falzone, Cristian; De Benedictis, Giulia M.; Bernardini, Marco
    Two young dogs were evaluated for an acute onset of abnormal head posture and eye movement. Neurological examination was characterized mostly by permanent neck extension, abnormalities of pupils, and eye movement. A mesencephalic mass lesion was detected on magnetic resonance imaging in both cases. Neurophysiological pathways likely responsible for this peculiar clinical presentation are discussed.

  18. Efficacy of a single-formula acupuncture treatment for horses with palmar heel pain

    Robinson, Katherine A.; Manning, Stephen T.
    Acupuncture is used without strong scientific evidence to treat many diseases of the horse, including palmar heel pain. Research is needed to provide evidence for the application of these treatments. Within the confines of our study, acupuncture did not reliably modulate palmar heel pain in horses.

  20. Evaluation of coagulation via thromboelastography in healthy horses administered dexamethasone

    Woodman, Jenna; Wagg, Catherine R.; Boysen, Søren R.; Leguillette, Renaud; Mizen, Kyle; Roy, Marie-France
    Dexamethasone was administered to healthy horses daily for 7 days. Blood samples were collected at 3 time points from both treatment and non-treatment groups, and analyzed via thromboelastography (TEG). There were no significant differences in TEG parameters between treated and untreated horses, or within treatment groups over time.
