Acute vision loss after general anesthesia in a cat

A 6‐year‐old, male castrated, domestic shorthair cat presented with a 2‐week history of blindness following general anesthesia. Behavioral changes, lethargy, inappetence and neurological deficits were also noted. Ophthalmic evaluation revealed blindness, normal pupillary light response and dazzle response, but no other abnormalities. Serodiagnostic testing for common infectious agents was negative and a cerebrospinal fluid analysis was normal. History and postmortem examination following euthanasia revealed cerebrocortical necrosis most consistent with anesthesia related hypoxia.     

Acute necrotizing myopathy in a dog

A 9 yr old spayed female cocker spaniel presented for an acute onset of weakness. Rhabdomyolysis and myoglobinuria were found 36 hr after presentation. The dog was managed for several electrolyte and mineral abnormalities and rhabdomyolysis-induced acute renal failure. The diagnosis of idiopathic necrotizing myopathy was determined by histopathology and by the exclusion of underlying infectious agents and metabolic defects. The dog recovered completely from the acute crisis and acute renal failure.     

Resolution of exfoliative dermatitis and Malassezia pachydermatis overgrowth in a cat after surgical thymoma resection

A four-year-old, male neutered domestic shorthaired cat was presented with a two-week history of nasal and ocular discharge, generalised exfoliative dermatitis, intense pruritus, polydipsia, polyphagia, weight loss, intermittent hindlimb ataxia and lethargy. Cutaneous populations of Malassezia pachydermatis yeast organisms were found to be elevated. The generalised nature of the disease prompted survey radiography which revealed the presence of a cranial mediastinal mass which was subsequently resected and found to be a thymoma. Within six months of surgery, systemic and cutaneous signs had resolved and yeast counts had returned to normal, suggesting a causal relationship between the thymoma and the skin disease.     

Acute herpesvirus-gastritis in a cat

Gastritis in cats is caused, among other things, by infectious agents, like bacteria, metazoic parasites or viruses. Herpesvirus-gastritis has not as yet been documented in cats. Therefore in this paper such a case will be described. In this case the mucous membrane of the stomach shows multifocal acute necroses with evidence of intranuclear inclusion bodies in epithelial cells of the gastric glands. By means of electron microscopy the causative virus can be specified as herpesvirus.     

Perivulvar dermatitis in a cat treated by episioplasty

Perivulvar dermatitis is common in obese, older female dogs that have infantile vulvae. Removing the excessive perivulvar skin folds by episioplasty has been recommended as the treatment of choice for perivulvar dermatitis in bitches. This report describes a case of perivulvar dermatitis in a cat that was treated by episioplasty. Ten days after surgery a substantial improvement was noticed, and 67 days later the skin in the perineal/perivulvar area appeared to be normal. The cat had not been given any medication. As in bitches, episioplasty in cats can be successful in reducing perivulvar dermatitis.     

Miliary dermatitis in the cat

Miliary dermatitis is a cutaneous response to disease states seen in the cat. It is not in itself a diagnosis. Conditions which may lead to miliary dermatitis lesions can be divided into hypersensitivity disorders, parasitic causes, infections and miscellaneous causes. A thorough investigation frequently leads to a diagnosis which enables specific therapy. Symptomatic, empirical therapy is less satisfactory and may in the long term cause side effects, The single most important cause of miliary dermatitis in the UK and elsewhere in the world is flea-bite hypersensitivity. Other important and increasingly recognised causes include atopy and food hypersensitivity. With determination and a thorough approach to diagnosis the number of idiopathic cases of miliary dermatitis are small.     

Acute monocytic leukaemia in a cat

A three-year-old cat with lymphadenopathy, non-regenerative anaemia and marked leucocytosis (171.3 x 10(9) white blood cells/l) was diagnosed with monocytic leukaemia and treated with a combination of anticancer drugs. A number of mature and immature monocyte-like cells were detected in the peripheral blood and bone marrow; they proved to be monocytic cells by cytochemical examination and an analysis of their cell surface phenotype, indicating that the cat suffered from acute myeloid leukaemia, subclassified as monocytic leukaemia (M5). Treatment with cytarabine, doxorubicin, vincristine and prednisolone greatly reduced the number of blast cells in the cat's peripheral blood and bone marrow. The cat was in partial remission for 67 days and survived for 95 days after it was first examined.     

Acute hemorrhagic and necrotizing pneumonia, splenitis, and dermatitis in a pet rabbit caused by a novel herpesvirus (leporid herpesvirus-4)

A 1.5-year-old female rabbit (doe) was presented with a 3-day history of lethargy, anorexia, and mild facial swelling. The animal died shortly after examination and severe, acute hemorrhagic pneumonia was noted grossly. An alphaherpesvirus consistent with leporid herpesvirus-4 was isolated and characterized from this animal. This is the first confirmed report of the disease in Canada.     

Effects of an insecticidal dip containing d-limonene in the cat

A study was undertaken to determine the effects of a single dermal application of a commercial insecticidal dip containing 78.2% d-limonene in cats. At the manufacturer's recommended concentration of 1.5 oz/gal of water, no clinical signs or lesions of toxicosis were seen. At 5 times the recommended concentration, clinical signs were mild and consisted of hypersalivation of short duration, ataxia, and muscle tremors resembling shivering. At 15 times the recommended concentration, clinical signs included hypersalivation lasting 15 to 30 minutes, moderate-to-severe ataxia lasting 1 to 5 hours, muscle tremors resembling shivering lasting 1 to 4 hours, and severe hypothermia beginning soon after treatment and lasting 5 hours. Gross lesions were confined to excoriation of the scrotal and perineal areas of the treated male cats at the 15 X concentration. No deaths or other lasting effects were seen at any dosage.     

Acute monoblastic leukemia in a FeLV-positive cat

A 1.6-year-old male domestic short hair cat was brought to the Veterinary Medical Teaching Hospital, Kasetsart University, with signs of severe anemia, depression, and general lymph node enlargement. Complete blood count revealed leukocytosis and massive undifferentiated blasts. Testing for antibodies specific to feline leukemia virus (FeLV) was positive, and FeLV nucleic acid was confirmed by nested polymerase chain reaction. Base on cytochemistry and ultrastructure, the cat was diagnosed with acute monoblastic leukemia.     

Comorbidity of ectopic thymoma-associated exfoliative dermatitis and pemphigus foliaceus in a cat

An 8-year-old cat was presented with pruritus, purulent paronychia, scaling, crusting, and spontaneous alopecia. Histopathology revealed intraepidermal neutrophilic pustular acantholytic dermatitis and hyperkeratotic cytotoxic interface dermatitis. No thoracic mass was seen on a lateral radiograph. Ectopic thymoma was discovered on necropsy. This case highlights the necessity for thorough investigation of any case of feline exfoliative dermatitis and pemphigus foliaceus for the presence of thymoma.Key clinical message:Comorbidity of exfoliative dermatitis and pemphigus foliaceus in a cat should prompt a thorough investigation for presence of a thymoma, possibly with advanced imaging techniques.     

Thymoma-associated exfoliative dermatitis with post-thymectomy myasthenia gravis in a cat

Thymoma-associated exfoliative dermatitis was suspected in a cat with a cranial mediastinal mass. The dermatopathy resolved with surgical removal of a thymoma. The cat manifested neurologic signs consistent with myasthenia gravis 7 wk after surgery. Exfoliative dermatitis and post-thymectomy myasthenia gravis in the same cat has not been reported previously.
