0–7–21 Radiation Therapy for the Treatment of Canine Oral Melanoma

Eighteen dogs with malignant melanoma of the oral cavity were treated with high-dose per fraction (0–7–21) radiation therapy. Eight hundred cGy was administered on days 0, 7, and 21 for a total dose of 2,400 cGy in 3 weeks. Of 17 dogs evaluated, 9 (53%) had a complete remission and 5 (30%) achieved a partial remission with an overall response rate of 83%. Local failure occurred in 2 of the 9 dogs where a complete response was initially observed. One dog died of intercurrent disease, and one died of metastatic disease without evidence of local recurrence. Five dogs are alive and free of disease 9 to nineteen months from the initiation of therapy. The 0–7–21 protocol was well-tolerated, and acute radiation reactions were low-grade and limited to the skin. The results of this study demonstrate that oral melanomas in dogs are responsive to radiation. 0–7–21 radiation therapy offers a viable alternative to radical excision, especially when tumor volume or location would require cosmetically or functionally debilitating surgery.     

Adverse events associated with pericardiocentesis in dogs: 85 cases (1999–2006)

Objective – To quantify the frequency of adverse events occurring during or post pericardiocentesis and to determine if adverse events are related to the cause of the pericardial effusion or frequency of pericardiocentesis.
Design – Retrospective study.
Setting – Referral hospital.
Animals, Intervention and Measurements – Medical records of 85 dogs that underwent 112 episodes of pericardiocentesis were reviewed. Any adverse events during pericardiocentesis and in the 48 hours post pericardiocentesis were noted. The frequency of adverse events was compared between dogs with a suspected neoplastic cause and a suspected nonneoplastic cause of their pericardial effusion and also between the first and subsequent pericardiocenteses.
Main Results – The incidence of adverse events was 10.7% within 1 hour of pericardiocentesis and 15.2% within 48 hours. There was no significant difference in the frequency of adverse events between the groups. Most adverse events identified were dysrhythmias. Forty-one percent of those dogs with adverse events were euthanized or died within 48 hours.
Conclusion – The incidence of adverse events seen within 48 hours of pericardiocentesis was 15.2%.     

Cellulitis in Japanese quail (Coturnix coturnix japonica)

A case of cellulitis was observed in Japanese quail (Coturnix coturnix japonica) reared for commercial meat production. This condition in Japanese quail has not been reported in the literature. This incident was the first, and to date only, occurrence of cellulitis in this processing plant. The cellulitis lesions were localized to the subcutis overlying the breast and inner thigh. Carcasses of processed birds and live birds from the affected farm were presented to the Poultry Diagnostic and Research Center, University of Georgia. Escherichia coli was cultured from the lesion. The affected live birds displayed lameness and had osteomyelitis. Pasteurella multocida serotype 3,4 was cultured from the liver and bone marrow of affected birds. Approximately 4.61% of the processed carcasses from the flock were condemned because of cellulitis. This represented a 10fold increase from the typical condemnation rate. Further investigation revealed birds were placed in higher than normal density; therefore, we theorize that the concurrent pasteurellosis and increased placement density resulted in the cellulitis condition.
