Effects of lithium carbonate on carboplatin-induced thrombocytopenia in dogs.

Objective: To describe the effects of lithium carbonate on thrombopoiesis in clinically normal dogs and in dogs treated with carboplatin.

Animals: 18 young adult sexually intact female Beagles.

Procedures: Dogs were assigned to each of 3 treatment groups (6 dogs/group).

Pneumopericardium associated with a pulmonary-pericardial communication in a dog.

A 6-year-old 18-kg (39-lb) spayed female Standard Poodle was referred for treatment of pneumopericardium. The dog did not have severe clinical signs relating to the pneumopericardium, and the diagnosis was made incidentally while investigating the cause of a cough. Computed tomography revealed an air-filled structure consistent with a bulla to the right of the heart base that appeared to communicate with the pericardial cavity Because spontaneous resolution of the pneumopericardium seemed unlikely and cardiac tamponade was a possibility, exploratory thoracotomy was performed.
