AN OUTBREAK OF ANAL FIBROPAPILLOMATOSIS IN COWS FOLLOWING RECTAL EXAMINATIONS

An outbreak of fibropapillomatosis following rectal examination for pregnancy and involving the anus and to a lesser extent the rectum in a herd of beef heifers in western Victoria is described. Almost half the herd were involved at one time; most lesions regressed with the following 16 weeks. Lesions varied from 0.2 mm diameter polyps up to large multiple lesions up to 7 x 5 x 2 cm with a broad base. The presence of lesions did not affect the body condition or health of the animals.     

A modified technique for surgical repair of oesophageal hiatal herniation in the dog

The surgical repair of oesophageal hiatal herniation in five dogs is described. The initial presenting signs included regurgitation, vomiting, hypersalivation, anorexia, coughing, dyspnoea and exercise intolerance. Diagnosis was based upon the clinical signs, plain radiography and contrast fluoroscopic examination. The hernias were corrected by a hiatal plication technique which moved the diaphragmatic oesophagus to a new anatomical position, a 360° oesophagopexy and a proximal fundic gastropexy. Surgical results were considered excellent in all cases.     

Comparison of capillary ear blood and arterial blood to validate capillary sampling as an accurate assay of blood gas in swine.

Capillary sampling in swine can be performed as an accurate assay of arterial blood gases. Studies with swine provided results similar to, or slightly more favorable than, those reported for human beings, depending upon which cutaneous technique was used on human beings. On the basis of free flow or arterilization of the cutaneous sample and of the correlation between capillary and arterial pH, CO2 partial pressure (PCO2), and O2 partial pressure (PO2) values, the capillary sampling technique of complete incisement of a 2-mm section from the tip of the warmed porcine ear could be a substitution technique for arterial blood sampling. Free flow with this technique was maximized and high correlation coefficients (r) for pH (r = 0.96), PCO2 (r = 0.82), and PO2 (r = 0.90) capillary-arterial values (n = 37) were obtained.
