A population-based cohort study of recipients of organs from donors with a recognized history or active cancer has been conducted by linking the Italian National Registry of Transplanted Patients and the National Registry of Donors with Neoplasia Risk. Between 2002 and 2004, 8,198 solid organ transplants have been performed in Italy, 108 of them with organs from 59 cadaveric donors with various risk of neoplasia. There were two reported cases of nonmelanoma skin cancer during the follow up of the transplanted patients, which lasted 27.6+/-11.3 months (234 patient-years). In our study, recipients of organs from donors with various degree of neoplasia risk are exposed to a low risk of cancer transmission.
BACKGROUND: This study examines the postoperative stability of the Mitek Bioknotless anchor system with biomechanical draw-out pulling in human cadaver shoulders. METHOD: With simulation of anterior shoulder dislocation a test group (n=10, Ø 45 years) was tested against a native group (n=8, Ø 47 years). All shoulders were dissected up to the passive stabilizers. In the test group an artificial Bankart lesion was created and repaired with three Mitek Bioknotless anchors. The humeri of both groups were fixed in 60 degrees glenohumeral abduction and 90 degrees external rotation and then dislocated in a ventral direction. For evaluation purposes the ultimate draw-out strength, mode of failure, translation of humeral head, capsular slope, and bone density in the test group were measured. RESULTS: In the test group the ultimate strength was a median of 937 N (min. 554 N, max. 1,294 N) with 28 bony anchor dislocations, 1 suture rupture, and 1 capsular rupture, and in the native group with 6 Bankart and 2 HAGL lesions it was 1,214 N (708 N, 1,471 N). The bone density showed a positive correlation to the draw-out strength regarding cortical density and total density. CONCLUSION: Regarding the high draw-out strength the Mitek Bioknotless anchor system provides enough stability for early functional treatment.
