There is a wide interest in epidemiologic studies assessing different causes of post-kidney transplantation rehospitalization. However, there is a paucity of knowledge on the long-term survival and graft function of rehospitalized kidney transplant recipients during the first year. Knowledge of posttransplant rehospitalization causes may help guide the preventive program at the first year. In our study, we assess causes for hospitalization and investigate the long-term patient and graft survival after non-fatal rehospitalization in kidney recipients during the first year. ⋯ During the first year after kidney transplantation, rehospitalization was especially required because of infections and renal dysfunction. The risk factors of rehospitalization were cadaveric graft, use of mycophenolate mofetil, use of cyclosporine, and cytomegalovirus infection. To prevent and minimize rehospitalizations during the first year, a specific preventive program based on infection prevention and graft function monitoring should be established.

Case Reports
Successful lung retransplantation after extended use of extracorporeal membrane oxygenation as a bridge.
Redo lung transplantation remains a major clinical challenge and its indication for patients with early allograft dysfunction is difficult to determine. We report a case of potentially fatal early allograft dysfunction owing to possible acute cellular rejection after single lung transplantation in a patient who underwent redo double lung transplantation after successful use of extracorporeal membrane oxygenation as a bridge, which resulted in a successful outcome.

Hepatocellular carcinoma (HCC) commonly develops in cirrhotic or noncirrhotic livers affected by congenital hemochromatosis. In patients with congenital hemochromatosis and HCC, liver transplantation is a therapeutic option with a 5-year posttransplantation survival rate as high as 80%. Herein is reported congenital hemochromatosis in a 37-year-old man. ⋯ At 20 months of rapamycin-based immunosuppression therapy, there were no signs of HCC recurrence. This is, to our knowledge, the first report of liver transplantation performed to treat suspected HCC based on the finding of IFF in congenital hemochromatosis, with histopathologic confirmation of the diagnosis of HCC after transplantation. According to this case and the current literature, IFF in patients with congenital hemochromatosis should be considered preneoplastic lesions vulnerable to possible development of HCC.

To assess knowledge and behavior relative to cadaveric organ donation and transplantation among physicians and nurses working at nine Portuguese hospitals. ⋯ The present study showed a lack of specific knowledge and training on organ donation and transplantation issue. It also suggested that for hospital staff to successfully act as initiators of the organ procurement process, more information and education are necessary. This effort could significantly increase the rate of organ donation and transplantation in Portugal.

Prolonged corrected QT (QT(c)) interval and vagal dysfunction are common occurrences in liver cirrhosis and are determinants of mortality in patients with chronic liver disease. We evaluated whether propranolol can affect the relationship between QT(c) interval and cardiac vagal control of heart rate variability (HRV) in cirrhotic patients awaiting liver transplantation. ⋯ The prolonged QT(c) interval observed in cirrhotic patients may be reduced by propranolol administration, an effect attributable to improved vagal cardiac modulation. These findings suggest that propranolol may have a beneficial effect on perioperative mortality in cirrhotic patients awaiting liver transplantation.
