The aim of our study was to assess the long-term liver histology in renal transplant patients infected with hepatitis C virus (HCV) who were treated with a cyclosporine-based regimen. Among 55 anti-HCV+/RNA+ patients, liver biopsies (LB) were requested every 3 to 4 years after transplantation: two LBs (n=55); three LBs (n=44); four LBs (n=10). Overall, the rate of liver fibrosis progression was 0.07+/-0.03 Metavir U/y. Only three patients out of 55 (5.4%) developed cirrhosis. Liver fibrosis remained stable throughout follow-up in 21 patients; increased in 21 patients; and improved in the remaining 13 patients. The incidence of posttransplant diabetes mellitus was low (9%). We concluded that HCV infection is not harmful to liver histology in more than 50% of renal transplant patients with grafts functioning more than 6 years. Cyclosporine might have beneficial effects on the natural course of HCV infection after renal transplantation.  相似文献

This paper demonstrates that discussions about the diagnosis of death and the meaning of states of suspended animation existed long before the publication of the Harvard criteria in 1968. The surgeons who started retrieving kidneys from heart beating cadavers have been accused to redefine death in order to obtain high quality organs. In fact, they were not aware of modifying a definition. They did not view death as a philosophical concept but considered that it was a biological phenomenon of which brain death was merely a new expression resulting from the development of resuscitation and intensive care procedures.  相似文献

Looking at the history of epididymal research provides a level of confidence in predictions of cause and effect that looking at the future cannot achieve. Thus, when one of us (Hamilton, 2002) wrote a short essay on the history of the testicular excurrent ducts it became fairly obvious that advances in understanding the epididymis followed advances in other fields, particularly those that provided new instrumentation to probe at ever finer levels of detail. Can this same theme lead to predictions about what will happen in epididymis research over the next century?  相似文献

Background

Concern exists over the quality, accuracy, and accessibility of online information about health care conditions. The goal of this study is to evaluate the quality, accuracy, and readability of information available on the internet about lateral epicondylitis.

Methods

We used three different search terms (“tennis elbow,” “lateral epicondylitis,” and “elbow pain”) in three search engines (Google, Bing, and Yahoo) to generate a list of 75 unique websites. Three orthopedic surgeons reviewed the content of each website and assessed the quality and accuracy of information. We assessed each website’s readability using the Flesch–Kincaid method. Statistical comparisons were made using ANOVA with post hoc pairwise comparisons.

Results

The mean reading grade level was 11.1. None of the sites were under the recommended sixth grade reading level for the general public. Higher quality information was found when using the terms “tennis elbow” and “lateral epicondylitis” compared to “elbow pain” (p < 0.001). Specialty society websites had higher quality than all other websites (p < 0.001). The information was more accurate if the website was authored by a health care provider when compared to non-health care providers (p = 0.003). Websites seeking commercial gain and those found after the first five search results had lower quality information.

Conclusions

Reliable information about lateral epicondylitis is available online, especially from specialty societies. However, the quality and accuracy of information vary significantly with the search term, website author, and order of search results. This leaves less educated patients at a disadvantage, particularly because the information we encountered is above the reading level recommended for the general public.  相似文献

Periprosthetic joint infection (PJI) remains a serious complication following a total knee replacement. Infections rates following arthroplasty range from 0.5% to 3%. The acutely infected knee replacement often presents to the on call Orthopaedic Surgeon who can often lack the expertise or resources for the definitive management. However, obtaining an early and accurate diagnosis and potentially performing an early treatment such as irrigation and debridement may be required by the on call surgeon. Management of these patients should include a team of specialists including Medical or Intensive Care, and Infectious Disease. Management of PJI is expensive, complicated and has a high morbidity. These patients should have their definitive care by specialist multidisciplinary teams on a regional basis.  相似文献
