Hyperandrogenism associated with an ovarian remnant in a spayed female cat.

Case Summary: An 11-year-old female, reportedly spayed, domestic shorthair cat was examined for a 4-month history of weight loss, aggression, urine spraying, malodorous urine and estrus-like behavior. Physical examination revealed thickened skin, a mildly prominent vulva and confirmed malodorous urine. On abdominal ultrasonography, a 6 mm hypoechoic nodule was found in the left cranial abdomen.

Pharyngeal mucoceles in dogs: 14 cases.

This report describes the clinical features of a series of dogs with pharyngeal salivary mucoceles. A retrospective study of 14 dogs with pharyngeal mucocele was performed. Medical records from 1983 to 2003 were reviewed for information regarding signalment, clinical signs, diagnosis, surgical procedures, and short-term and long-term outcome.

Ovarian remnant syndrome in dogs and cats: 21 cases (2000-2007).

Objective: To describe signalment, clinical findings, diagnostic tests, and results of treatment of dogs and cats with ovarian remnant syndrome (ORS).

Design: Retrospective case series.

Animals: 19 dogs and 2 cats with ORS.

Cryptorchidism.

Cryptorchidism is a common clinical problem in dogs and cats. Retained testes can be unilateral or bilateral, are usually small and atrophied, and vary in location. These factors make diagnosis and surgical removal challenging in some animals.

Results of excision of thymoma in cats and dogs: 20 cases (1984-2005).

Objective: To provide long-term follow-up information for a series of dogs and cats with invasive and noninvasive thymomas treated by excision alone.

Design: Retrospective case series.

Animals: 9 cats and 11 dogs with thymoma.

Surgical correction of brachycephalic syndrome in dogs: 62 cases (1991-2004).

Objective: To assess results of surgical correction of brachycephalic syndrome (including stenotic nares, elongated soft palate, and everted laryngeal saccules) in dogs and determine whether dogs with hypoplastic trachea have a less favorable long-term outcome.

Design: Retrospective case series.

Animals: 62 dogs with brachycephalic syndrome.

Thyroidectomy in the cat.

Thyroidectomy in cats is most commonly indicated to treat hyperthyroidism because of adenomatous hyperplasia of the thyroid glands. Preoperative stabilization of the hyperthyroid cat with antithyroid drugs is preferred to minimize anesthetic and surgical complications. Multiple surgical techniques for thyroidectomy have been reported, and results of surgery and complications differ between techniques.

Sodium nitroprusside-induced deliberate hypotension to facilitate patent ductus arteriosus ligation in dogs.

Objective: To report the use of sodium nitroprusside to induce deliberate hypotension to reduce hemorrhage and facilitate surgical ligation of complicated patent ductus arteriosus (PDA) in dogs.

Study Design: Retrospective study.

Animals: Six dogs.

Transvenous coil embolization of portosystemic shunt in dogs.

This paper describes transvenous coil embolization of portosystemic shunt in 10 dogs. Clinical signs resolved in 4 dogs with extrahepatic shunt, and in 3 dogs with intrahepatic shunt. Two dogs of less than 3 kg died because of migration of coils to the level of the main pulmonary artery.

Portosystemic shunt in an alpaca cria.

A 5-month-old alpaca cria was examined for chronic poor growth and repeated episodes of diarrhea. Examination of feces for parasites yielded negative results. Serum bile acid and blood ammonia concentrations were high.
