Nuclear angiography in a dog with congestive cardiomyopathy

Nuclear angiography was used as a diagnostic aid and in monitoring the clinical course of a case of congestive cardiomyopathy in a dog. Serial examinations revealed progressively deteriorating values for left ventricular ejection fraction before the dog's death. This noninvasive technique can be an alternative to echocardiography for the evaluation of cardiac performance.     

Systemic autoimmune disease and concurrent nematode infection in a dog

Systemic lupus erythematosus was diagnosed in a dog with concurrent nematode infection. The clinical signs of disease were unusually severe and included multiple neurologic deficits, polyarthritis, and weight loss. The dog was thrombocytopenic, and serotest results included positive lupus erythematosus test, positive rheumatoid factor test, positive antinuclear antibody test, hypergammaglobulinemia, and high platelet-associated IgG concentration. After treatment of hookworm, whipworm, and heartworm infections concurrently with corticosteroid and empiric treatment, the dog's condition improved. However, 10 days later, cyclophosphamide administration was necessary for continued immunosuppression. The dog was euthanatized because of progressive deterioration and development of canine coronavirus diarrhea. Serotest data generated from the dog's serum obtained at the time of referral suggested that autoantibodies and circulating immune complexes may have included IgE isotypes.     

Toxic Myopathy in a Dog Associated with the Presence of Monensin in Dry Food

This report describes a case of toxic myopathy in a two year old sheltie dog with clinical signs of profound weakness, myoglobinuria, and muscle enzyme elevations. The clinical signs were likely related to the accidental inclusion of monensin sodium in the dog's food. This food was prepared by a small feed milling company that also prepares cattle and chicken rations. A change of dog food resulted in remission of the clinical signs.     

Fatal thrombocytopenic hemorrhagic diathesis associated with dapsone administration to a dog

Dapsone was given for six days to a dog with chronic skin disease. The dog then became weak and anorectic, and it vomited and had purpura caused by severe thrombocytopenic hemorrhagic diathesis. Despite treatment, the dog died a week later. There were clinical and pathologic evidence that the dog's platelets and megakaryocytes had been destroyed during the first few days of dapsone therapy. It was concluded that the syndrome was dapsone-induced and that thrombocytopenia should be considered among the adverse reactions to dapsone in the dog.     

Palliative intravenous cisplatin treatment for concurrent peritoneal and pleural mesothelioma in a dog

A 10-year-old Maltese dog was presented with abdominal distention and dyspnea. Cytological examination of pleural and peritoneal effusion was suggestive of malignant effusion of glandular origin. Numerous, multifocal, tan to white nodules were disseminated throughout the surface of the abdominal organs and peritoneum at biopsy. Histologically, the tumors were revealed to be an epithelial type of mesothelioma. Neoplastic cells co-expressed cytokeratin and vimentin. Intravenous administration of cisplatin was chosen as the treatment. During treatment, the dog's overall body condition improved and the clinical signs were relieved without significant side effects. The survival time from diagnosis to sudden death by unknown cause was 153 days.     

Allergic inhalant dermatitis attributable to marijuana exposure in a dog

Exposure to marijuana was believed to be responsible for clinical signs consistent with allergic inhalant dermatitis in a dog. The dog had facial and pedal pruritus associated with bilateral ocular discharge. Clinical signs resolved when the dog was kenneled, but returned when the dog was returned to its home. The results of intradermal skin testing, using a standard tray of 51 inhalant extracts, did not adequately account for the dog's clinical signs. Later, the owners indicated that previous residents of the owners' home had cultivated marijuana intensively inside and outside of the home. Intradermal skin testing with a source of marijuana pollen extract was performed, yielding a positive reaction in the dog and a negative reaction in another dog without clinical or historical evidence of allergic inhalant dermatitis. The affected dog was treated successfully and exclusively by hyposensitization with marijuana pollen extract.     

Eumycotic mycetoma caused by Pseudallescheria boydii in a dog

Abdominal eumycotic mycetoma caused by Pseudallescheria boydii was diagnosed in a 3-year-old male Siberian Husky. The dog was examined because of weight loss and signs of depression. Initially, pyrexia was the only clinical finding. Antibiotic and corticosteroid treatment was ineffective. Two weeks later, the dog's appetite had decreased, it had vomited a few times, and the caudal portion of the abdomen was sensitive to palpation. Hematologic and serum biochemical abnormalities consisted of anemia, leukocytosis, hypoglycemia, hypoalbuminemia, hyperglobulinemia, and high alkaline phosphatase activity. One week later, the dog's condition continued to worsen, and testicular swelling was observed. The dog was castrated. Microscopic examination of specimens obtained at surgery revealed pyogranulomatous periorchitis with mycetoma granules. Ketoconazole treatment was initiated and continued until the dog died one month later. Necropsy revealed multifocal duodenal ulcers, with transmural pyogranulomatous enteritis, pancreatitis, and peritonitis. This case is unique because the etiologic agent apparently entered via the intestinal tract rather than by contamination of an external wound.     

犬瘟抑制蛋白对犬瘟热的疗效观察

本试验研究不同剂量犬瘟抑制蛋白对犬瘟热的疗效,将犬瘟热试纸检测阳性的病犬24只,随机分为4组,每组6只,分别为对照组、试验1组、试验2组、试验3组。对照组治疗为犬瘟热单克隆抗体、犬干扰素及其对症输液治疗,试验1组为犬瘟抑制蛋白（20IU/kg）、犬干扰素,并结合输液（抗生素和能量合剂等）对症治疗。试验2组为犬瘟抑制蛋白（40IU/kg）、以下同上。试验3组为犬瘟抑制蛋白（60IU/kg）、以下同上。结果表明对照组与试验2组、试验3组其疗效比较明显。试验2组与试验3组的剂量不同,但其疗效一致,故试验2组为犬瘟抑制蛋白（40IU/kg）最佳使用剂量。     

Diabetes insipidus and hyperadrenocorticism associated with high plasma adrenocorticotropin concentration and a hypothalamic/pituitary mass in a dog

Central diabetes insipidus was diagnosed in association with a dexamethasone-insuppressible adrenocorticotropin-secreting tumor in a dog. Over the 3 years before the dog's death, the combination of specific pituitary function tests, peptide hormone radioimmunoassays, and visualization of the tumor by use of x-ray computed tomography of the skull, allowed an etiologic diagnosis. Because initial signs of glucocorticoid excess were questionable and adrenolytic therapy was not allowed by the owners, treatment consisted only of administration of synthetic vasopressin, which was successful in the management of the diabetes insipidus.     

Atrial rupture and pericardial effusion as a complication of chronic mitral valve endocardiosis

A 9-year-old Labrador mixed breed dog, known to suffer from heart disease, was presented. It had recently collapsed on the street. Based on clinical findings and ultrasonography the tentative diagnosis of an atrial rupture with bleeding into the pericardial sac, resulting into a cardiac tamponade, was made. The dog's state of health improved under treatment, including infusion, sedation and analgesia. Therefore pericardiocentesis was unnecessary. The dog was released from hospital the next evening and the medical therapy of its heart disease was continued. The animal died 85 days later.
