Relationship between cervical spine injury and helmet use in motorcycle road crashes.
Motorcycle helmets have been proven to prevent head injury and reduce fatality in road crashes. However, certain studies indicate that the helmet increases the mass to the head, and thus the potential of neck injury due to the flexion/extension of the head-neck segment in a road crash may increase. This study was conducted to evaluate the effects of motorcycle helmets and the ways in which the accidents that occurred affected the incidence of cervical spine injury. ⋯ However, in the latter crash modes, a motorcyclist without a helmet will have to trade-off with head injury. A logistic regression model has been developed with respective crash modes and the probabilities of risk in having severe cervical spine injury have been calculated. Future designs in motorcycle helmets should therefore consider the significance of nonfrontal accidents and the interaction of helmet with other parts of the body by possibly considering the weight of the helmet.

Factors associated with successful resuscitation of out-of-hospital cardiac arrest at Rajavithi Hospital's Narenthorn Emergency Medical Service Center, Thailand.
The objective of this study is to determine factors associated with successful resuscitation of out-of-hospital cardiac arrest (OHCA) patients by Narenthorn Emergency Medical Service Center (EMS), Thailand. A retrospective observational study was conducted with 73 OHCA patients who were resuscitated from December 2004 to January 2007. Inferential statistics, univariate (χ(2)) and multivariate analyses (logistic regression) were applied for data analysis. ⋯ RT showed a trend toward statistical significance (OR = 1.051; 95% CI = 0.765-16.083). This study found that witnessed arrest and bystander CPR were major factors associated with successful resuscitation of OHCA patients. Our findings will be useful for the development of community programs to decrease the mortality from OHCA.
