Seventy-two horses with recent onset of navicular syndrome and normal radiographs were assessed. Horses underwent magnetic resonance (MR) imaging of both front feet. All abnormalities were characterized and the most severe abnormality identified, if possible. Abnormal signal intensity in the navicular bone was the most severe abnormality in 24 (33%) horses. Pathologic change in the deep digital flexor tendon was the most severe abnormality in 13 (18%) horses. Pathologic change in the collateral sesamoidean ligament was the most severe abnormality in 11 (15%) horses. Pathologic change in the distal sesamoidean impar ligament was the most severe abnormality in seven (10%) horses. Multiple abnormalities were observed in 13 (18%) horses in which an abnormality that was more severe than the others could not be determined. Abnormalities were not observed in the navicular bone or its supporting soft tissues in four (5%) horses. Fifty-six horses had abnormalities that were most severe in one limb; in 52 (93%) horses, the most severe abnormalities were in the foot of the most lame limb. In 7% (4/56) of horses, the most severe findings were in the opposite limb, and in 16 horses, the findings on both limbs were similar. MR imaging is a useful technique for evaluating horses with navicular syndrome and can differentiate between multiple abnormalities. This provides a more specific diagnosis which affects further treatment of the horse. Pathologic changes in different locations in the foot can cause similar clinical signs that, before MR imaging, were categorized as one syndrome. 相似文献

Fractures of the tibial malleoli are relatively uncommon injuries, and most frequently affect the lateral malleolus. They most commonly occur following falls. The tibial malleoli have extensive collateral ligament attachments, and this is likely to contribute to fracture pathogenesis. Although most fractures are best managed by surgical removal, large fractures should be repaired as removal may result in tarsal instability. Arthroscopic removal has recently become the standard of care for most fractures, and good results can be expected following surgery. 相似文献

Although fungal disease is uncommon in rodents, dermatophytosis is the most common mycosis seen in clinical practice. T. mentagrophytes is the most common etiologic agent, and the guinea pig is the most common species affected, although there are reports in all pet and laboratory rodent species except the gerbil. Despite the low incidence of clinical disease, rodents are common asymptomatic carriers of dermatophytes, and ringworm is the most common zoonotic disease transmitted from rodents to people. 相似文献

甲基丙烯酸甲酯在真丝上接枝共聚反应条件的优化 总被引：1，自引：0，他引：1
对有引发剂和无引发剂存在时甲基丙烯酸甲酯对真丝接枝增重的工艺条件进行研究,并用正交试验法探讨了不同的温度、时间、单体质量浓度等对接枝增重效果的影响。有引发剂的接枝聚合反应最佳工艺条件为反应温度80℃、单体质量浓度50g/L、反应时间40min;反应温度和单体质量浓度对接枝率的影响极其显著,反应时间对接枝率的影响不显著。无引发剂的接枝聚合反应最佳工艺条件为反应温度80℃、单体质量浓度55g/L、反应时间3h,反应温度对接枝率的影响极其显著,反应浓度对接枝率的影响比较显著,反应时间对接枝率的影响不显著。 相似文献

Objectives To determine (1) the common types of canine splenic disorders, and the breeds affected, that are diagnosed by cytopathological and histopathological examination in Sydney, Australia and (2) the accuracy of cytopathological examination compared with histopathological examination for the diagnosis of canine splenic disorders. Design 69 cytopathological and 51 histopathological diagnoses of canine splenic disorders presented to the Veterinary Pathology Diagnostic Services, The University of Sydney during 2006 and 2007 were tabulated and analysed; 17 cases examined both cytopathologically and histopathologically during 2001–07 were also analysed. Results The most common cytopathological diagnoses were benign disorders of growth, vascular disturbances and necrosis (29%), followed by no abnormalities detectable (28%), malignant neoplasms (20%), equivocal diagnoses (20%) and inflammatory disorders (3%). The most common breeds were Kelpie crosses and mixed breeds. The most common histopathological diagnoses were benign disorders of growth, vascular disturbances and necrosis (49%), followed by malignant neoplasms (43%) and inflammatory disorders (8%). The most common breeds were German Shepherd Dogs, Boxers and Maltese Terriers. Cytopathological and histopathological diagnoses were in complete agreement in 59% of cases, partial agreement in 29% and disagreement in 12%. Conclusion Benign disorders of growth, vascular disturbances and necrosis were the most commonly diagnosed canine splenic disorders, both cytopathologically and histopathologically. Kelpie crosses presented most frequently for cytopathological examination. German Shepherd Dogs were the most common breed diagnosed histopathologically with haemangiosarcoma. Although cytopathological and histopathological splenic examinations are complementary for diagnosis, this study has shown a high correlation for complete and partial agreement between the two. 相似文献

The clinicopathologic aspects of bacterial osteomyelitis in 67 dogs were compared. The femur, humerus, metacarpals, metatarsals, and phalanges were the bones most commonly affected. In most dogs, the infection was attributed to repair of fracture by open reduction. Staphylocuccus spp and Streptococcus spp were the organisms most frequently isolated. Most dogs had chronic osteomyelitis at the time of initial examination. 相似文献

Osteosarcoma (OSA) is the most common primary bone tumour in dogs. The appendicular locations are most frequently involved and large to giant breed dogs are commonly affected, with a median age of 7–8 years. OSA is a locally invasive neoplasm with a high rate of metastasis, mostly to the lungs. Due to similarities in biology and treatment of OSA in dogs and humans, canine OSA represents a valid and important tumour model. Differences between canine and human OSAs include the age of occurrence (OSA is most commonly an adolescent disease in humans), localisation (the stifle is the most common site of localisation in humans) and limited use of neoadjuvant chemotherapy in canine OSA. 相似文献
