Functional metastatic parathyroid adenocarcinoma in a dog - Kishi, Erin N.; Holmes, Shannon P.; Abbott, Jeffrey R.; Bacon, Nicholas J.
A 12-year-old dachshund dog was presented for persistent hypercalcemia and hyperparathyroidism despite bilateral parathyroidectomy. Magnetic resonance imaging of the head, neck, and cranial mediastinum identified an increased number of cranial mediastinal lymph nodes with heterogeneous signal intensity. Hypercalcemia and hyperparathyroidism resolved after surgery to remove multiple cranial mediastinal lymph nodes, one of which contained presumed metastatic parathyroid tissue.
Neurotropic T-cell-rich B-cell lymphoma in a 14-year-old Morgan gelding - Westerman, Trina L.; Poulsen, Keith P.; Schlipf, John W.; Valentine, Beth A.
A 14-year-old Morgan gelding was presented for progressive weakness and muscle atrophy. The horse was initially diagnosed with equine protozoal myelitis based on history, physical examination, and laboratory diagnostics. Despite therapy, the horse declined clinically and was euthanized. Necropsy revealed a rare form of neurotropic lymphoma, described in this report.
Uncommon acute neurologic presentation of canine distemper in 4 adult dogs - Galán, Alba; Gamito, Araceli; Carletti, Beatrice E.; Guisado, Alicia; de las Mulas, Juana Martín; Pérez, José; Martín, Eva M.
Four uncommon cases of canine distemper (CD) were diagnosed in vaccinated adult dogs. All dogs had acute onset of neurologic signs, including seizures, abnormal mentation, ataxia, and proprioceptive deficits. Polymerase chain reaction for CD virus was positive on cerebrospinal fluid in 2 cases. Due to rapid deterioration the dogs were euthanized and CD was confirmed by postmortem examination.
Epizootic hemorrhagic disease in a yak - Raabis, Sarah M.; Byers, Stacey R.; Han, Sushan; Callan, Robert J.
Epizootic hemorrhagic disease virus (EHDV) infection was diagnosed in a 3-year-old yak. The yak had signs of intermittent tremors, dysphagia, oral ulcerative lesions, hemorrhagic enteritis, tachypnea, and thrombocytopenia. Postmortem diagnostics confirmed EHDV (serotype 2) using reverse-transcriptase polymerase chain reaction (RT-PCR). Gross and histopathological results were consistent with EHDV reported in other species.
Epidermoid cyst of the ileum in a miniature dachshund dog - Shimamura, Shunsuke; Kainuma, Risa; Kimura, Ken; Okamura, Yasuhiko; Kobayashi, Saori; Katayama, Masaaki; Sato, Reeko; Yasuda, Jun
A 13-year-old castrated male miniature dachshund dog was presented with chronic vomiting and diarrhea. Contrast radiography and surgical exploration revealed an ileal cyst, which was excised. A diagnosis of epidermoid cyst was made from a combination of the clinical findings and histological examination of the surgical specimen.
Diurnal variations of central corneal thickness and intraocular pressure in dogs from 8:00 am to 8:00 pm - Martín-Suárez, Eva; Molleda, Carolina; Tardón, Rodrigo; Galán, Alba; Gallardo, José; Molleda, José
Diurnal variations in central corneal thickness (CCT) and intraocular pressure (IOP) and their relationships were studied in healthy dogs. Central corneal thickness was measured by ultrasonic pachymetry and IOP by applanation tonometry in 16 beagle dogs. Measurements were taken every 90 min over 12 h (08:00 am to 08:00 pm). The mean CCT and IOP values obtained during the sampling period were 545.6 ± 21.7 μm (range: 471 to 595 μm) and 15 ± 2.2 mmHg (range: 10 to 19 mmHg), respectively. The CCT and IOP showed statistically significant decreases at 6:30 pm and 5:00 pm, respectively (P < 0.001)....
Long-term outcome of permanent tracheostomies in dogs: 21 cases (2000–2012) - Occhipinti, Lindsay L.; Hauptman, Joe G.
This retrospective study reports long-term outcome, survival, and complications in dogs which received a permanent tracheostomy due to upper airway obstruction. Data were collected from medical records (n = 21) in 2 institutions over a 12-year period. Patients were followed until death, complications, causes of death, and survival times are reported. Major complications were reported in 50% of patients with 20% of patients receiving revision surgery. The most common complications were aspiration pneumonia and need for revision surgery. Median survival time was 328 days with 25% of patients surviving 1321 days or longer. Some (26%) patients died acutely at home...
Retrospective risk factor assessment for complication following tibial tuberosity transposition in 137 canine stifles with medial patellar luxation - Stanke, Natasha J.; Stephenson, Nicole; Hayashi, Kei
This study identified risk factors for complication following tibial tuberosity transposition by retrospective examination of cases that used various surgical techniques. Records and radiographs of 113 dogs with 137 stifles undergoing tibial tuberosity transposition for medial patellar luxation were reviewed. Patient-specific factors, surgical factors, and complication information were recorded. Owners were contacted as necessary to attain a minimum of 30 days follow-up. Of 137 stifles, 59 (43%) had complications, with 24 (18%) identified as major complications. Factors significantly associated with reduced risk of complication included increased age [odds ratio (OR) 0.8] and concurrent cranial cruciate ligament rupture (OR 0.3). Factors...
Antimicrobial susceptibility of Escherichia coli F4, Pasteurella multocida, and Streptococcus suis isolates from a diagnostic veterinary laboratory and recommendations for a surveillance system - Glass-Kaastra, Shiona K.; Pearl, David L.; Reid-Smith, Richard J.; McEwen, Beverly; Slavic, Durda; McEwen, Scott A.; Fairles, Jim
Antimicrobial susceptibility data on Escherichia coli F4, Pasteurella multocida, and Streptococcus suis isolates from Ontario swine (January 1998 to October 2010) were acquired from a comprehensive diagnostic veterinary laboratory in Ontario, Canada. In relation to the possible development of a surveillance system for antimicrobial resistance, data were assessed for ease of management, completeness, consistency, and applicability for temporal and spatial statistical analyses. Limited farm location data precluded spatial analyses and missing demographic data limited their use as predictors within multivariable statistical models. Changes in the standard panel of antimicrobials used for susceptibility testing reduced the number of antimicrobials available for...
Effects of xylazine, romifidine, or detomidine on hematology, biochemistry, and splenic thickness in healthy horses - Kullmann, Annie; Sanz, Macarena; Fosgate, Geoffrey T.; Saulez, Montague N.; Page, Patrick C.; Rioja, Eva
Alpha-2 agonist-induced changes in packed cell volume (PCV), total solids (TS), selected biochemical parameters, and splenic thickness were investigated in horses. Four healthy mares were treated in a blinded, randomized, cross-over design with a dose of xylazine (0.5 mg/kg), romifidine (0.04 mg/kg), or detomidine (0.01 mg/kg) IV, and detomidine (0.02 mg/kg) IM. Hematology, TS, colloid osmotic pressure (COP), plasma osmolality; glucose, lactate, urea (BUN) and electrolyte concentrations; venous blood pH and ultrasonographic splenic thickness were evaluated at intervals for 300 min. Repeated measures analysis of variance (ANOVA) were performed with P < 0.05. There was a significant change over time...
