Comparative Study
Prospective evaluation of multidetector computed tomography for extremity vascular trauma.
Multidetector computed tomographic angiography (MDCTA) is increasingly being used for the assessment of extremity vascular injury. However, to date, there are only retrospective series and a single small prospective study evaluating its efficacy. Therefore, the objective of this study was to prospectively evaluate the ability of MDCTA to detect arterial injury in the injured upper and lower extremities. ⋯ Physical examination is critical in the decision-making process for the injured extremity and can accurately reduce unnecessary imaging. If imaging is required, MDCTA is a sensitive and a specific noninvasive modality for arterial evaluation and may replace conventional angiography as the diagnostic modality of choice for the evaluation of the acutely injured extremity.

Comparative Study
Upper extremity injuries in restrained front-seat occupants after motor vehicle crashes.
Prior studies identified that crash severity (delta V), occupant position, and restraint systems as reliable predictors of crash injuries to lower extremity, but very little have been written on the subject of upper extremity. ⋯ Further improvement in vehicle safety performance in the form of "depowered" airbag and efficient energy absorbing material within the vehicle interior is warranted.

Randomized Controlled Trial
The role of preconditioning and N-acetylcysteine on oxidative stress resulting from tourniquet-induced ischemia-reperfusion in arthroscopic knee surgery.
The aim of this study was to investigate the effects of ischemic preconditioning (IPC) and N-acetylcysteine (NAC) on oxidative stress resulting from tourniquet-induced ischemia-reperfusion (IR) period in arthroscopic knee surgery. ⋯ Tourniquet-induced IR period in routine arthroscopic knee surgery resulted in oxidative stress by increasing MDA, SOD, GSH-Px, TOS and decreasing TAC. NAC and IPC had protective effect on occurrence of oxidative stress resulting from IR period by preventing MDA, SOD, GSH-Px, TAC, and TOS changes in routine arthroscopic knee surgery.
