Traffic normalization, i.e. enforcing a constant stream of fixed-length packets, is a well-known measure to completely prevent attacks based on traffic analysis. In simple configurations, the enforced traffic rate can be statically configured by a human operator, but in large virtual private networks (VPNs) the traffic pattern of many connections may need to be adjusted whenever the overlay topology...
To determine how many men with high-risk prostate cancer (prostate-specific antigen [PSA] >20ng/ml or biopsy Gleason score 8–10) have positive lymph nodes (sentinel lymph nodes [SLNs] and nonsentinel lymph nodes [NSLNs]) and whether these positive nodes are localised in the region of SLN dissection or in other regions, too.In 228 men with high-risk prostate cancer radical retropubic prostatectomy...
We determined the incidence of positive pelvic lymph nodes in men undergoing radical retropubic prostatectomy and describe the correlation with prostate specific antigen, histological grade and stage. We examined whether tumor cells are localized in the sentinel nodes only or also in other nonsentinel lymph nodes.A total of 1,055 men with prostate cancer underwent radio guided pelvic lymph node dissection...
