Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
The influence of urban, suburban, or rural locale on survival from refractory prehospital cardiac arrest.
There are many variables that can have an effect on survival in cardiopulmonary arrest. This study examined the effect of urban, suburban, or rural location on the outcome of prehospital cardiac arrest as a secondary end point in a study evaluating the effect of bicarbonate on survival. The proportion of survivors within a type of EMS provider system as well as response times were compared. ⋯ There was no difference in time to bystander cardiopulmonary resuscitation, but medical response time (basic life support) was decreased for suburban or urban sites, and intervention (ACLS) and transport times were decreased for suburban sites alone. Although response times were differentiated by location, they were not necessarily predictive of survival. Factors other than response time such as patient population or resuscitation skill could influence survival from cardiac arrest occurring in diverse prehospital service areas.

It is not exactly known how ED physicians perform in evaluating cardiac systolic murmurs. In 203 consecutive medical ED patients with systolic murmur, we compared the initial clinical evaluation, including auscultation, with transthoracic echocardiography. Of the 203 patients, 132 (65%) had innocent murmurs and 71 patients (35%) had valvular heart disease. ⋯ Independent significant positive predictors of valvular heart disease were grade >2/6 systolic murmur (odds ratio [OR], 8.3; confidence interval [CI], 3.5-19.7, P<.001) and pathologic electrocardiogram (ECG) (OR, 8.4; CI, 3.2-22, P<.001. Patients younger than 50 years with a systolic murmur graded < or =2/6 had innocent murmurs in 98%. The initial clinical evaluation, including auscultation, by experienced ED physicians in internal medicine distinguishes well between innocent murmurs and valvular heart disease in medical patients with cardiac systolic murmurs.

Clinicians may not perform a medical-legal examination in cases in which a sexual assault was attempted but no penile-vaginal contact occurred. This retrospective study was conducted to document the frequency and type of genital injuries in women in whom forced digital penetration was the only reported type of assault. Study patients were consecutive female patients presenting to an urban sexual assault clinic during a 3-year study period. ⋯ Fifty-six percent of the injuries occurred at four sites: fossa navicularis, labia minora, cervix, and posterior fourchette. The most common type of injury was erythema (34%) followed by superficial tears (29%) and abrasions (21%). Colposcopy with nuclear staining was useful in detecting these injuries--and can provide valuable legal information in sexual assault victims reporting only digital-vaginal penetration.
