Review Meta Analysis Comparative Study
Systematic review and meta-analysis of laparoscopic versus open colectomy with end ileostomy for non-toxic colitis.
This review compared short-term outcomes after laparoscopic versus open subtotal colectomy for acute, colitis medically refractory. ⋯ Where the procedure can be completed laparoscopically, there may be short-term benefits over open colectomy for colitis. These results cannot be generalized to critically ill patients in need of an emergency subtotal colectomy.

Comparative Study
Surface and mechanical analysis of explanted Poly Implant Prosthèse silicone breast implants.
The recent events surrounding Poly Implant Prosthèse (PIP) breast implants have renewed the debate about the safety profile of silicone implants. The intentional use of industrial-grade instead of certified medical-grade silicone is thought to be responsible for reportedly higher frequencies of implant rupture in vivo. The differences in mechanical and viscoelastic properties between PIP and medical-grade silicone implant shells were investigated. Surface characterization of shells and gels was carried out to determine structural changes occurring after implantation. ⋯ This study demonstrated an increased weakness of PIP shells with time and therefore supports the argument for prophylactic removal of PIP breast implants.

Randomized Controlled Trial
Late effects of a brief psychological intervention in patients with intermittent claudication in a randomized clinical trial.
The authors previously reported the early results of a trial of a brief psychological intervention to increase physical activity in patients with intermittent claudication. After 4 months, participants in the intervention group walked a mean of 1576 more steps per day than control group participants. The present study followed the original participants to determine whether this behaviour change was maintained over 2 years. ⋯ ISRCTN28051878 (http://www.controlled-trials.com).
