To validate the Ottawa ankle rules to predict fractures in a French clinical setting when they are used by physicians not involved in their development. ⋯ Use of the Ottawa ankle rules by French emergency physicians not involved in the rules' development resulted in 99% sensitivity and had a potential of reducing radiography requests by 33%.

To characterize trends in annual estimates of nonfatal firearm-related injuries treated in US hospital emergency departments and to compare trends in quarterly rates of such injuries with those of firearm-related fatalities in the US population. ⋯ Analysis of national trends indicates that non-fatal and fatal firearm-related injuries are declining in the United States, although the rate of firearm-related deaths remains high, especially among males aged 15 to 24 years, in relation to other leading causes of injury death. An assessment of factors responsible for the decline in firearm-related injuries is needed to design further prevention efforts.

Multicenter Study Comparative Study Clinical Trial
Multicenter comparison of two clinical decision rules for the use of radiography in acute, high-risk knee injuries.
Two separate clinical decision rules, one developed in Ottawa and the other in Pittsburgh, for the use of radiography in acute knee injuries have been previously validated and published. In this study, the rules were prospectively validated and compared in a new set of patients. ⋯ Prospective validation and comparison found the Pittsburgh rule for knee radiographs to be more specific without loss of sensitivity compared with the Ottawa rule.
