Feline lung-digit syndrome: A differential diagnosis for shifting, waxing and waning lameness in a cat.

The clinical presentation, cytologic findings, radiographic findings, and postmortem assessment of a cat with primary pulmonary adenocarcinoma with multiple digital metastasis are described. An unusual shifting, waxing and waning pattern of lameness, suspected to be an early manifestation of digital metastasis before any gross lesions were visible, was documented. Initial cytologic finding of a lung nodule was equivocal for diagnosis of neoplasia despite being strongly suspicious.

Histologic, immunohistochemical, and scanning electron microscopic comparison of pre-iridal monocellular and fibrovascular membranes in normal and glaucomatous canine globes.

Objectives: (i) To evaluate immunohistochemical labeling of pre-iridal monocellular and fibrovascular membranes and (ii) describe the light and scanning electron microscopic (SEM) characteristics of these membranes in glaucomatous and normal/control canine globes.

Materials And Methods: All globes were evaluated with light microscopy. Immunohistochemical labeling for CD18, Smooth muscle actin (SMA), and CD117 was completed on 40 canine globes with congenital/anterior segment dysgenesis-associated glaucoma (n = 10), primary/goniodysgenesis-associated glaucoma (n = 10), secondary glaucoma (n = 10), and normal/control globes (n = 10).

Canine adenovirus type 1 causing neurological signs in a 5-week-old puppy.

Background: Infectious canine hepatitis is a rarely encountered disease, that is caused by Canine Adenovirus-1. Clinical signs can vary dramatically, and neurological signs are rarely seen. Neurological manifestation of this disease is rarely reported in the veterinary literature.

Bovine astrovirus infection in feedlot cattle with neurological disease in western Canada.

A novel bovine astrovirus (BoAstV CH13/NeuroS1) has been associated with encephalitis in cattle in Europe and the USA. We retrospectively analyzed feedlot cattle with encephalitis of unknown etiology for this virus by hybridization. Results suggest that BoAstV CH13/NeuroS1 is a major cause of encephalitis in western Canadian feedlot cattle.

An unusual lipomatous brain mass in a Golden Retriever dog.

A 9-year-old Golden Retriever dog was presented to the Veterinary Medical Center with a 3-week history of grand mal seizures and was subsequently euthanized. At autopsy, a discrete, firm, expansile mass was found in the right pyriform lobe, which compressed the ipsilateral hippocampus, thalamus, and cerebral cortex. Histologically, the mass was composed of well-differentiated adipose tissue supported by fibrous and mucinous stroma.

A retrospective study of non-suppurative encephalitis in beef cattle from western Canada.

Non-suppurative encephalitis occurs sporadically in beef cattle in western Canada, leading to loss of animals. This retrospective study investigated the presence of viral, bacterial, and protozoal antigens or DNA in 37 western Canadian feedlot cattle with non-suppurative encephalitis for which a cause had not been identified. Cases were selected based on the age of the animal (> 7 months), and clinical history of recumbency and depression.

A case of biphasic mesothelioma with osseous and chondromatous differentiation in a cat.

An 11-year-old domestic short hair cat with dyspnea, cyanosis, and pleural effusion died. Necropsy revealed several nodules and masses on the parietal pleura, pericardium, and diaphragm. The tumor contained epithelial and mesenchymal components and displayed osseous and chondromatous differentiation.

Canine brucellosis in a Saskatchewan kennel.

Canine brucellosis is rare in Canada. This report describes an outbreak of Brucella canis infection within a kennel, emphasizing diagnostic and pathologic findings. Gender differences are described.

Bartonella vinsonii subsp. berkhoffii endocarditis in a dog from Saskatchewan.

A dog referred for lameness was diagnosed with culture-negative endocarditis. Antibodies to Bartonella spp. were detected.
