Objective—To evaluate associations among etiologic classifications of seizures and signalment, clinical signs, and outcome in cats with various seizure disorders.

Study Design—Retrospective case series.

Animals—91 cats evaluated for seizure disorders at a veterinary teaching hospital from 2000 through 2004.

Procedures—Data regarding characteristics of the cats and their seizures were obtained from medical records. Seizures were classified as reactive, symptomatic, or idiopathic. Survival times were displayed as Kaplan-Meier curves, and differences between etiologic classifications were assessed by log-rank test.

Results—Over the 5-year period, the incidence of seizures among all cats evaluated at the hospital was 2.1%. Etiology was classified as reactive in 20 (22%) cats, symptomatic in 45 (50%), idiopathic or presumptive idiopathic in 23 (25%), and cardiac syncope in 3 (3%). Focal seizures with or without secondary generalization were recorded for 47 (52%) cats, and primary generalized seizures with or without status epilepticus were recorded for 44 (48%). Etiology was not associated with seizure type. However, mean age of cats with idiopathic seizures (3.5 years) was significantly lower than that of cats with reactive seizures (8.2 years) or symptomatic seizures (8.1 years). The 1-year survival rate for cats with idiopathic seizures (0.82) was longer than that for cats with reactive (0.50) or symptomatic (0.16) seizures.

Conclusions and Clinical Relevance—Seizure etiology was symptomatic or reactive in most cats. Underlying disease was not associated with seizure type. Cats with idiopathic seizures lived longer than did cats with reactive or symptomatic seizures but were also younger.

To determine whether administration of misoprostol prevents gastric hemorrhage in healthy dogs treated with high doses of methylprednisolone sodium succinate (MPSS).


18 healthy hound-type dogs of both sexes.


All dogs were given high doses of MPSS (30 mg/kg of body weight, initially, then 15 mg/kg 2 and 6 hours later, and, subsequently, q 6 h for a total of 48 hours) IV. Dogs were assigned randomly to receive concurrent treatment with misoprostol (4 to 6 μg/kg, PO, q 8 h; n = 9) or an empty gelatin capsule (9). Gastroduodenoscopy was performed before and after treatment. Hemorrhage was graded from none (0) to severe (3) for each cardia, fundus, antrum, and duodenum. A total stomach score was calculated as the sum of the regional stomach scores. Food retention was recorded, and pH of gastric fluid was determined. Gastric and fecal occult blood was measured.


Gastric hemorrhage was evident in all dogs after MPSS administration, and its severity was similar in both groups. Median total stomach score was 6 for misoprostol-treated dogs and 5.5 for dogs given the gelatin capsule. Difference in gastric acidity, frequency of food retention, and incidence of occult blood in gastric fluid and feces was not apparent between the 2 groups.

Conclusions and Clinical Relevance

Administration of misoprostol (4 to 6 μg/kg, PO, q 8 h) does not prevent gastric hemorrhage caused by high doses of MPSS. Alternative prophylactic treatment should be considered. (Am J Vet Res 1999;60:982–985)
