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.

An economic evaluation of the parent-child assistance program for preventing fetal alcohol spectrum disorder in Alberta, Canada.

Parent-Child Assistance Program (P-CAP) is a 3-year home visitation/harm reduction intervention to prevent alcohol exposed births, thereby births with fetal alcohol spectrum disorder, among high-risk women. This article used a decision analytic modeling technique to estimate the incremental cost-effectiveness ratio and the net monetary benefit of the P-CAP within the Alberta Fetal Alcohol Spectrum Disorder Service Networks in Canada. The results indicate that the P-CAP is cost-effective and support placing a high priority not only on reducing alcohol use during pregnancy, but also on providing effective contraceptive measures when a program is launched.

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.

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.

Cellular evaluation of the toxicity of combustion derived particulate matter: influence of particle grinding and washing on cellular response.

There is increasing interest in continual monitoring of air for the presence of inhalation health hazards, such as particulate matter, produced through combustion of fossil fuels. Currently there are no means to rapidly evaluate the relative toxicity of materials or to reliably predict potential health impact due to the complexity of the composition, size, and physical properties of particulate matter. This research evaluates the feasibility of utilizing cell cultures as the biological recognition element of an inhalation health monitoring system.

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.

Surgical treatment of adrenocortical tumors: 21 cases (1990-1996).

Twenty-four adrenocortical tumors were surgically removed from 21 dogs. Histopathological examination confirmed 18 carcinomas and six adenomas. Four dogs died in the perioperative period.

Comparison of a continuous suture pattern with a simple interrupted pattern for enteric closure in dogs and cats: 83 cases (1991-1997).

Objective: To describe and compare a simple continuous suture pattern with a simple interrupted pattern for enterotomy closure or end-to-end intestinal anastomosis.

Design: Retrospective study.

Animals: 58 dogs and 25 cats that underwent enterotomy or intestinal resection and anastomosis.
