The prevalence of canine H3N8 influenza and human H1N1 and H3N2 influenza in dogs in Ohio was estimated by conducting serologic tests on 1,082 canine serum samples. In addition, risk factors, such as health status and age were examined. The prevalences of human H1N1, H3N2, and canine H3N8 influenzas were 4.0%, 2.4%, and 2.3%, respectively. Two samples were seropositive for two subtypes (H1N1 and H3N2; H1N1 and canine influenza virus [CIV] H3N8). Compared to healthy dogs, dogs with respiratory signs were 5.795 times more likely to be seropositive against H1N1 virus (p = 0.042). The prevalence of human flu infection increased with dog age and varied by serum collection month. The commercial enzyme-linked immunosorbent assay used in this study did not detect nucleoprotein-specific antibodies from many hemagglutination inhibition positive sera, which indicates a need for the development and validation of rapid tests for influenza screening in canine populations. In summary, we observed low exposure of dogs to CIV and human influenza viruses in Ohio but identified potential risk factors for consideration in future investigations. Our findings support the need for establishment of reliable diagnostic standards for serologic detection of influenza infection in canine species.

Of the congenital coronary artery fistulae, the multiple coronary artery microfistulae, arising from the left and right coronary artery emptying into the left ventricle, are very rare. Little is known about their anatomic and clinical features, especially in apical hypertrophic cardiomyopathy. The clinical findings are heterogeneous, but include, in most cases, a history of typical or atypical angina pectoris. A 67 year old woman was referred for evaluation of chest pain on exertion, and a shortness of breath. The electrocardiographic and echocardiographic findings were typical of apical hypertrophic cardiomyopathy. Coronary arteriography showed normal epicardial coronary arteries, but multiple coronary artery-left ventricular microfistulae arising from the left and right coronary arteries. Transthoracic Doppler echocardiography, using a high frequency transducer, with a low Nyquist limit, demonstrated multiple coronary artery-left ventricular microfistulae just beneath the apical impulse window.
