A 34-year-old woman presented with cyanosis and a methemoglobin level of 23.2% after perineal application of a topical anesthetic cream containing 20% benzocaine. Many commonly used products contain high levels of benzocaine, and their use can lead to life-threatening methemoglobin levels. This case reinforces the need for stricter guidelines for product use and warning labels to alert consumers to this potential side effect of topical benzocaine-containing products sold over the counter.

To measure the incremental cost-effectiveness of various improvements to emergency medical services (EMS) systems aimed at increasing survival after out-of-hospital cardiac arrest. ⋯ The most attractive options in terms of incremental cost-effectiveness were improved response time in a two-tier EMS system or change from a one-tier to a two-tier EMS system. Future research should be directed toward identification of the costs of instituting the first tier of a two-tier EMS system and identification of cost-effective methods of improving response time.

Meta Analysis
Effectiveness of emergency medical services for victims of out-of-hospital cardiac arrest: a metaanalysis.
To determine the relative effectiveness of differences in response time interval, proportion of bystander CPR, and type and tier of emergency medical services (EMS) system on survival after out of hospital cardiac arrest. ⋯ Increased survival to hospital discharge may be associated with decreased response time interval and with the use of a two-tier EMS system as opposed to a one-tier system. The data available for this analysis were suboptimal. Policymakers need more methodologically rigorous research to have more reliable and valid estimates of the effectiveness of different EMS systems.

In 1992, a study of the prevalence and predictors of domestic violence victims among individuals who presented to a major public hospital emergency department was conducted to replicate a study conducted by the authors in the same setting 12 months previously. The second study aimed to investigate more accurately the presentation of current victims of domestic violence to the ED. ⋯ These Australian studies support the findings of prevalence studies of domestic violence victims in ED in the United States. The prevalence and risk factors indicate the need for training of physicians and nurses in the ED about domestic violence and for provision of appropriate backup referral services such as after-hours social work services.

To describe the development, design, and validation of an emergency department protocol for the identification, documentation, and referral of victims of domestic violence. ⋯ We identified many obstacles to implementation of an ED domestic violence screening and referral protocol, demonstrating that evaluation is imperative in determining actual clinical impact.
