Sinus Node Sparing Hybrid Thoracoscopic Ablation Outcomes in Patients with Inappropriate Sinus Tachycardia (SUSRUTA-IST) Registry.

Background: Medical treatment of inappropriate sinus tachycardia (IST) remains suboptimal. Radiofrequency sinus node (RF-SN) ablation has poor success and higher complication rates.

Objective: We aimed to compare clinical outcomes of the novel SN sparing hybrid ablation technique with those of RF-SN modification for IST management.

Electron microscopic study of canine Babesia gibsoni infection.

Canine babesiosis is a tick-borne parasitic disease caused by the intraerythrocytic parasites, Babesia canis and Babesia gibsoni. A lethargic, weak, American Staffordshire Terrier (pit bull) dog, which had regenerative, normocytic, normochromic anemia, was shown by polymerase chain reaction analysis to be infected with B. gibsoni.

Multiple animal intoxications associated with Carolina jessamine (Gelsemium sempervirens) ingestions.

Neurological signs characterized by marked progressive weakness and convulsions culminating in death were observed in 3 goats over a 24-h period. Affected animals were in a group of 5 goats confined toa fenced paddock: a domestic goose within the paddock was also found dead. Present in the same paddock, but unaffected, were 2 other goats and an adult cow.

Thymic hematoma in juvenile dogs associated with anticoagulant rodenticide toxicosis.

Ten cases of thymic hematoma in young dogs (9-24 weeks of age) were reviewed. Anticoagulant rodenticide toxicosis was confirmed in 5 cases. Histologically, hemorrhage caused variable expansion of thymic lobules and interlobular septa.
