The seizuring cat. Diagnostic work-up and therapy.

Practical Relevance: Although seizures occur less commonly in cats compared with dogs, they are one of the most common forms of neurological disease in the feline patient. Cats may experience both focal (partial) and generalized seizures and causes are divided into primary disorders, in which there is no underlying cause (ie, idiopathic epilepsy), and secondary disorders. Cats with secondary seizure disorders have either an underlying structural lesion or metabolic disease.

Primary pulmonic infundibular stenosis in 12 cats: natural history and the effects of balloon valvuloplasty.

Objectives: To evaluate the natural history of primary pulmonic infundibular stenosis in cats and the effects of balloon valvuloplasty.

Background: Primary pulmonic infundibular stenosis is an uncommon congenital defect in cats. The natural history of the disease has not been described.

Clinical and echocardiographic findings of pulmonary artery stenosis in seven cats.

Objectives: Describe the clinical, electrocardiographic (ECG), radiographic and echocardiographic findings in cats with isolated pulmonary artery stenosis. Assess the usefulness of systolic and diastolic Doppler measurements at predicting stenosis severity.

Background: Pulmonary artery stenosis is an infrequent congenital cardiac defect in humans that has not been reported in cats.

Signalment, clinical signs, and prognostic indicators associated with high-grade second- or third-degree atrioventricular block in dogs: 124 cases (January 1, 1997-December 31, 1997).

Objective: To evaluate signalment, clinical signs, and prognosis associated with high-grade second- or third-degree atrioventricular block (AVB) in dogs.

Design: Retrospective case series.

Animals: 124 dogs.

Balloon valvuloplasty of valvular pulmonic stenosis in the dog.

Balloon valvuloplasty has become the accepted method of therapy for the majority of dogs with valvular pulmonic stenosis. Success rate of balloon valvuloplasty is excellent but the procedure can have a steep learning curve. An understanding of the equipment used and specifics of the procedure is important to maximize success and minimize risk.

Tibial fractures.

Tibial fractures are common in small animal practice. As with other appendicular fractures, the patient's age, fracture location, and fracture type must be considered thoroughly. While methods for tibial fracture repair are similar to those used for appendicular fractures elsewhere, there are some unique considerations, both anatomically and functionally, that must be contemplated before repair.

Serum total thyroxine, total triiodothyronine, free thyroxine, and thyrotropin concentrations in dogs with nonthyroidal disease.

Objective: To determine whether nonthyroidal disease of various causes and severity is associated with abnormalities in baseline serum concentrations of total thyroxine (T4), triiodothyronine (T3), free T4, or thyrotropin (thyroid-stimulating hormone [TSH]) in dogs believed to be euthyroid.

Design: Case-control study.

Animals: 223 dogs with confirmed nonthyroidal diseases and presumptive normal thyroid function, and 150 clinically normal dogs.

Serum total thyroxine, total triiodothyronine, free thyroxine, and thyrotropin concentrations in epileptic dogs treated with anticonvulsants.

Objective: To determine whether administration of phenobarbital, potassium bromide, or both drugs concurrently was associated with abnormalities in baseline serum total thyroxine (T4), triiodothyronine (T3), free T4, or thyrotropin (thyroid-stimulating hormone; TSH) concentrations in epileptic dogs.

Design: Prospective case series.

Animals: 78 dogs with seizure disorders that did not have any evidence of a thyroid disorder (55 treated with phenobarbital alone, 15 treated with phenobarbital and bromide, and 8 treated with bromide alone) and 150 clinically normal dogs that were not receiving any medication.

Hypertrophic osteopathy associated with an intrathoracic neoplasm in a rabbit.

Hypertrophic osteopathy associated with an intrathoracic neoplasm was diagnosed in a 7.5-year-old spayed female White New Zealand rabbit. The rabbit was examined because it had a swollen foot and was anorectic.

Canine leptospirosis in New Jersey and Michigan: 17 cases (1990-1995).

The clinical, laboratory, and serological findings in 17 dogs with disease resulting from leptospiral infection were evaluated retrospectively. Acute renal failure was the most common syndrome, but cholestatic hepatic disease also was common. The most prevalent serovars identified were pomona, grippotyphosa, and autumnalis.

Cecal-colic volvulus in two dogs.

Cecal-colic volvulus was confirmed by surgery in two dogs. Both dogs were intact, male Great Danes. The clinical and diagnostic findings were not specific for large bowel volvulus.
