Conventional and molecular epidemiology of trimethoprim-sulfamethoxazole resistance among urinary Escherichia coli isolates.

Background: Antibiotic resistance is increasing in Escherichia coli, the most common cause of urinary tract infections, but its epidemiology has not been well described. We evaluated the epidemiology of trimethoprim-sulfamethoxazole-resistant E. coli in a large, public health care system in Denver, Colorado.

Defibrillation and thrombolysis following a myocardial infarct in Antarctica.

This report describes the cardiac resuscitation and air evacuation of a 53-yr-old male dentist who sustained an inferior myocardial infarction and cardiac arrest in Antarctica. Following defibrillation and thrombolysis, a ski-equipped LC-130 airlifted this critical patient 9 h north to New Zealand for angioplasty. This case heralds the rapidly evolving ability to extend state-of-the-art health care to previously inaccessible areas.
