Swab specimens for bacterial culturing were obtained from 82 consecutive dogs and 13 cats undergoing open reduction and internal fixation of 110 fractures. Bacteria were isolated from 51 wounds. When the data were analyzed by stepwise logistic regression, it was found that bacterial contamination of wounds was associated most often with open fractures and with tibia or radius/ulna fractures. Contaminated wounds were five times more likely to develop complications than those without bacterial contamination. Regardless of results of bacterial culturing, postoperative complications developed significantly more often in animals that were febrile (>39.4° C [103° F]). Postoperative complications did not develop in animals that did not have bacterial contamination of wounds and were not febrile. 相似文献

An osteosarcoma developed in the proximal femur of a 9-year-old female Great Dane. The femur had been fractured 5 years previously and was stabilized with plate fixation with the incorporation of a frozen cortical bone allograft. The dog recovered without complications after the surgery and had normal use of the leg before the osteosarcoma developed. The tumor had metastasized to the lungs, spleen, and ipsilateral popliteal lymph node. 相似文献

Analytical procedures were developed to monitor furosemide concentrations in post-race serum and urine samples obtained from horses participating in an exercise-induced pulmonary haemorrhage (EIPH) program. High performance liquid chromatography with ultraviolet light detection proved a reliable, sensitive method for measuring urinary furosemide concentrations up to 12 h after administration of either 150 or 250 mg of the drug to race horses. However, this method was unreliable for determination of serum furosemide concentration. High performance liquid chromatography with fluorescence detection proved a reliable, sensitive method for measuring serum furosemide concentrations in horses administered 250 mg of the diuretic, permitting detection approximately 5–10 ng/ml 6 h after treatment. This method was applied field conditions where furosemide was administered to horses (between 150 and 250 mg intravenously) 4 h prior to the race. Analytical results assisted establishing a threshold concentration of 85 ng/ml for serum furosemide. was found that serum furosemide concentrations are a valid measure of compliance with furosemide administration in the EIPH program. 相似文献

A review of the clinical and pathologic evaluation of allogeneic bone grafts is presented with particular emphasis upon partial joint replacement. The histologic evaluation of cortical bone transplantation is reviewed. Radiographic evaluation of cortical bone transplants is presented in an attempt to understand the normal events that take place in incorporation of the graft by the host. The histologic and radiographic correlation is related to the healing process. Current methods of graft collection and storage are reviewed. While collection of the graft is fairly uniform, there are many varied treatment and storage procedures. General surgical procedures used in performing full cortical bone grafts are reviewed. The clinical use of an osteoarticular allogeneic bone graft in the elbow of a dog is presented, with a review of the operative and postoperative evaluation of the clinical patient. 相似文献

Seeds of many plant species are secondarily dispersed by dung beetles, but the outcome of this interaction is highly context‐specific. Little is known about how certain anthropogenic disturbances affect this plant–animal interaction. The aims of this study were to assess the effect of dung type on secondary dispersal by dung beetles in a forest fragment, and to determine whether this interaction is affected by edge effects. Using pitfall traps, we captured dung beetles attracted to dung of 2 frugivorous mammals: woolly monkeys and howler monkeys. We found differences between both dung beetle assemblages, but these differences were not consistent in time. Using seeds surrounded by both dung types, we carried out a field experiment using seeds of 2 plant species. We found that the probability of secondary dispersal by dung beetles was higher for seeds placed in woolly monkey dung. Finally, we carried out a field experiment using plastic beads as seed mimics to assess edge effects. We found that secondary seed dispersal by dung beetles was negatively affected by edges. The disruption of plant–animal interactions along anthropogenic forest edges could have long‐term negative effects on forest dynamics by affecting processes of regeneration. 相似文献
