Background: Renal transplant recipients have an increased cancer risk. The mammalian target of rapamycin inhibitor sirolimus (SRL) has immunosuppressive and antitumour activities but knowledge about its use in recipients with cancer is limited.

Methods: We retrospectively analysed 726 renal allograft recipients converted to SRL from 10 German transplant centres.

Background: Sirolimus is an established immunosuppressant in renal transplantation with antineoplastic and antiviral features, but side effects like proteinuria limit its use. The aim of this retrospective multicenter observational study is to define predictors for determining which patients most likely benefit from a sirolimus-based therapy.

Methods: All patients from 10 German centers that were switched to a sirolimus-containing maintenance immunosuppression in 2000 to 2008 after 3 months or later post-transplantation were enrolled (n = 726).

The German Sirolimus Study Group has established a database among 10 transplant centers throughout Germany to study the outcomes in 726 renal transplant patients being converted to a sirolimus-containing therapy between 2000 and 2008 with a total of more than 1500 recorded patient years on therapy. In this study, we present a detailed description of the cohort, of characteristic changes over the observation period, proteinuria and graft survival, and new-onset proteinuria after conversion. Over the study period, age, graft function at the time of conversion, and the proportion of patients switched to sirolimus because of malignancy increased, whereas the proportion of patients with significant proteinuria at conversion decreased.

Mastitis originating from a fistula from intramediastinal esophago-jejunostomy following gastrectomy is an extremely rare event. We report on a 79-year old woman who had undergone repeated surgery due to recurrent breast abscesses for more than a year. The patient's history showed gastrectomy and esophago-jejunostomy two years earlier, with subsequent undetected insufficiency of the anastomosis and inflammation of the breast.

The present study examined non-insulin-treated streptozotocin (STZ)-induced diabetic rats to determine the role of kinins in diabetic nephropathy. Their involvement in the renoprotective effect of the angiotensin-converting enzyme inhibitor (ACEI) ramipril was investigated using the bradykinin (BK) B(2)-receptor antagonist, icatibant (HOE 140), or a combination of the two drugs.Although, none of the treatments prevented the decline of the glomerular filtration rate (GFR) in diabetic rats, ramipril (3 mg/kg/day), but not icatibant (HOE 140; 500 microg/kg/day), prevented proteinuria in these animals.
