Differential survival in horses requiring end-to-end jejunojejunal anastomosis compared to those requiring side-to-side jejunocaecal anastomosis     

Proudman CJ  Edwards GB  Barnes J 《Equine veterinary journal》2007,39(2):181-185

REASONS FOR PERFORMING STUDY: Horses requiring different methods of intestinal anastomosis during equine colic surgery may have differences in mortality and morbidity. HYPOTHESES: Horses requiring side-to-side jejunocaecal anastomosis have a higher mortality and morbidity rate than those requiring end-to-end jejunojejunal anastomosis. Morbidity and mortality of handsewn vs. stapled side-to-side jejunocaecal anastomoses are not significantly different. METHODS: A prospective, nonrandomised, observational study was conducted. Clinical and surgical details were recorded during hospitalisation and survival data acquired by periodic telephone questionnaire. Differences in mortality and morbidity rate were evaluated by survival analysis. RESULTS: A total of 184 horses underwent end-to-end jejunojejunal anastomosis and 178 underwent side-to-side jejunocaecal anastomosis. Horses with a jejunocaecal anastomosis had a significantly higher mortality rate. The incidence of post operative colic in horses requiring side-to-side jejunocaecal anastomoses was greater than those requiring end-to-end jejunojejunal anastomoses. Within the group undergoing side-to-side jejunocaecal anastomosis there was no evidence of differential survival between horses with handsewn vs. stapled anastomoses. CONCLUSIONS: Mortality rate is higher in horses that have required side-to-side jejunocaecal anastomosis than in those that needed end-to-end jejunojejunal anastomosis; and post operative colic is more common after side-to-side jejunocaecal anastomosis. No difference in mortality was found between horses with handsewn and stapled side-to-side jejunocaecal anastomoses. POTENTIAL RELEVANCE: Surgeons should be aware of the increased mortality and morbidity in horses requiring side-to-side jejunocaecal anastomosis. Our finding of no difference in mortality between handsewn and stapled side-to-side jejunocaecal anastomoses justifies surgeons exercising personal preference in their selection of anastomosis method.  相似文献   

Evaluation of an Immunochromatographic Test to the Diagnosis of Canine Brucellosis Caused by Brucella canis          下载免费PDF全文

This study evaluated the performance of an immunochromatographic test (ICT) for the diagnosis of canine brucellosis caused by Brucella canis, comparing its results with that of the rapid slide agglutination test with and without the use of 2‐mercaptoethanol and the agar gel immunodiffusion test (AGID). The microbiological culture, PCR and clinical examination were used as reference. According to the results obtained in clinical examination, blood culture, culture of semen and vaginal swab and PCR in blood, semen and vaginal swab, a total of 102 dogs were divided into three groups: B. canis‐infected dogs (Group 1), B. canis‐non‐infected dogs (Group 2) and dogs with suspected brucellosis (Group 3). The diagnostic sensitivity of RSAT, 2ME‐RSAT, AGID and ICT in Group 1 was, respectively, 75%, 37.5%, 27.8% and 89.58%. The diagnostic specificity of RSAT, 2ME‐RSAT, AGID and ICT in Group 2 was, respectively, 91%, 100%, 100%, and 100%. In dogs with suspected brucellosis, 9.67% were RSAT positive, none was positive by 2ME‐RSAT, 3.22% were AGID positive and 6.45% were ICT positive. The main drawback concerning canine brucellosis diagnosis is the lack of a highly sensitive serological assay to be used as a screening test to the rapid identification of infected animals. The ICT showed a high diagnostic specificity and a diagnostic sensitivity value greater than that observed in the RSAT, 2ME‐RSAT and AGID. However, 10.41% of infected dogs had negative results by ICT. These dogs were positive by microbiological culture and/or PCR, indicating active infection and consequently a higher potential of spreading Brucella. Although rapid and simple to perform, the ICT lacked sensitivity to be used as a screening test.  相似文献

Global Oscillation Network Group data reveal that the internal structure of the sun can be well represented by a calibrated standard model. However, immediately beneath the convection zone and at the edge of the energy-generating core, the sound-speed variation is somewhat smoother in the sun than it is in the model. This could be a consequence of chemical inhomogeneity that is too severe in the model, perhaps owing to inaccurate modeling of gravitational settling or to neglected macroscopic motion that may be present in the sun. Accurate knowledge of the sun's structure enables inferences to be made about the physics that controls the sun; for example, through the opacity, the equation of state, or wave motion. Those inferences can then be used elsewhere in astrophysics.  相似文献

Equine cestodosis: a sero-epidemiological study of Anoplocephala perfoliata infection in Ethiopia

A 12/13 kDa antigen, tapeworm ELISA test, developed for use in horses, was used to detect parasite-specific serum antibody, IgG(T), in the serum of donkeys. In a pilot study the 12/13 kDa antigen was tested and proved to detect the antibody, IgG(T), in donkey sera. Blood samples from 797 donkeys, naturally exposed to cestode infection, from four geographical localities were collected and sera were prepared and analysed. There was substantial serological evidence that donkeys were potentially infected with A. perfoliata. A range of ELISA OD values were obtained from the serological assay. Over 26% and 7.5% of the donkeys were moderately and highly infected, respectively, showing at least a 34% sero-prevalence. The rest, 66.1%, were either with low infection intensity or negative for A. perfoliata infection. The risk of infections, both in sero-prevalence and intensity, as determined by ELISA optical density (OD), were highest in the highland areas of Ethiopia where pastures are low-lying and wet, and permanent pasture management is regularly practised. Sex, age and body condition of the donkeys had no significant effect either on prevalence of the infection or on the serum antibody level. These results indicate a risk of intestinal disorders, particularly, colic, associated with A. perfoliata infection in donkeys.  相似文献
