Clinical Trial
Clobetasol ameliorates aphthous ulceration in renal transplant patients on sirolimus.
Aphthous ulceration is a common side effect of sirolimus. These lesions of the oral mucous membranes are often painful and debilitating, leading to either dose reduction or discontinuation of sirolimus in a significant number of patients. We report that the direct application of clobetasol, a high potency topical steroid, led to prompt resolution of the aphthous ulcers that developed in our renal transplant patients on sirolimus-based immunosuppression.

Epstein-Barr virus (EBV) infection is linked to approximately 90% of B-cell lymphomas associated with posttransplant lymphoproliferative disease (PTLD), a serious complication for immunosuppressed transplant recipients. In this paper, we review the myriad ways by which EBV can inadvertently drive the genesis and persistence of B-cell lymphomas, particularly when the antiviral immune response is compromised. Probing the basic mechanisms by which EBV infection proceeds and contributes to malignancy in such cases will hopefully improve our understanding and treatment of PTLD and other EBV-associated malignancies.

This article examines the Organ Procurement and Transplantation Network/Scientific Registry of Transplant Recipients data on heart and lung transplantation in the United States from 1996 to 2005. The number of heart transplants performed and the size of the heart waiting list continued to drop, reaching 2126 and 1334, respectively, in 2005. Over the decade, post-transplant graft and patient survival improved, as did the chances for survival while on the heart waiting list. ⋯ Death rates for both candidates and recipients have been dropping, as has the time spent waiting for a lung transplant. Other lung topics covered are living donation, recent surgical advances and changes in immunosuppression regimens. Heart-lung transplantation has declined to a small (33 procedures in 2005) but important need in the United States.

Review Meta Analysis
Efficacy and safety of antifibrinolytic drugs in liver transplantation: a systematic review and meta-analysis.
Although several randomized controlled trials (RCTs) have shown the efficacy of antifibrinolytic drugs in liver transplantation, their use remains debated due to concern for thromboembolic complications. None of the reported RCTs has shown a higher incidence of these complications in treated patients; however, none of the individual studies has been large enough to elucidate this issue completely. We therefore performed a systematic review and meta-analysis of efficacy and safety endpoints in all published controlled clinical trials on the use of antifibrinolytic drugs in liver transplantation. ⋯ Aprotinin and TA both reduced transfusion requirements compared with controls. No increased risk for hepatic artery thrombosis, venous thromboembolic events or perioperative mortality was observed for any of the investigated drugs. This systematic review and meta-analysis does not provide evidence for an increased risk of thromboembolic events associated with antifibrinolytic drugs in liver transplantation.

Multicenter Study
Traumatic memories of relatives regarding brain death, request for organ donation and interactions with professionals in the ICU.
Little is known about the memories of relatives after they have been confronted with the brain death of a loved one and the request for organ donation. We conducted this study, guided by Grounded Theory, to explore relatives' experiences, their interactions with health care providers and what influenced their memories. ⋯ Long-term memories of bereaved relatives were influenced by the characteristics of their decision-making style (clear vs. ambivalent) and the perceived quality of the interaction with professionals on the intensive care unit. Organ-focused behavior of professionals and an ambivalent decision-making style of relatives appear to be risk factors for traumatic memories.
