Transient hypertension after percutaneous transluminal renal artery angioplasty.

A retrospective analysis of 128 technically successful percutaneous transluminal renal angioplasty (PTRA) procedures was performed. After the procedures, transient systemic hypertension (TSH) developed in 39 patients. The phenomenon usually occurred within 30 minutes of balloon dilation and always within 2 hours of PTRA. TSH lasted less than 5 hours in 35 patients and never persisted for more than 24 hours. TSH is a self-limiting process and should not be confused with the more sustained hypertension that arises from a complication of balloon angioplasty

Are Passfaces More Usable Than Passwords? A Field Trial Investigation

The proliferation of technology requiring user authentication has increased the number of passwords which users have to remember, creating a significant usability problem. This paper reports a usability comparison between a new mechanism for user authentication Passfaces - and passwords, with 34 student participants in a 3-month held trial. Fewer login errors were made with Passfaces, even when periods between logins were long, On the computer facilities regularly chosen by participants to log in, Passfaces took a long time to execute. Participants consequently started their work later when using Passfaces than when using passwords, and logged into the system less often, The results emphasise the importance of evaluating the usability of security mechanisms in field trials
