Emergency physicians are trained to separate "sick" from "not sick" patients during their training. Nevertheless, every emergency physician will face situations in which early intervention is critical to their patient's outcome. Infectious diseases are responsible for many of these potentially poor outcomes. This article discusses early identification and treatment for several rapidly fatal infections, including two newly identified travel-related illnesses.

ReviewUrinary tract infections: diagnosis and management in the emergency department.
With the emergence of increasing resistance to common antibiotics used to treat urinary tract infections (UTIs), including ciprofloxacin and trimethoprim-sulfamethoxazole (TMP-SMX), the choice of antibiotics for these infections has become more challenging. In this article, the authors review the evidence-based guidelines for the evaluation and treatment of cystitis and pyelonephritis in the emergency department. ⋯ The treatment section reviews the current recommendations and also highlights the use of nitrofurantoin in the treatment of uncomplicated UTIs. The authors also discuss the appropriate use of ciprofloxacin and TMP-SMX in the treatment of UTIs.

Pneumonia remains one of the most common reasons for admission of emergency department (ED) patients to the hospital. Pneumonia also remains one of the most common causes of death in our patients. As with many emergent conditions, the ED management of these patients initiated by ED physicians contributes greatly to the survival and successful management of these patients. Specifically, the recognition of severe pneumonias, precise choice of diagnostic tests, and appropriate antibiotics can have an impact on the outcome.

While few patients with foodborne illness present with life-threatening symptoms, there are a number of foodborne infectious diseases and toxins that the emergency physician or other health care provider must consider in the evaluation of these patients. Given the frequency of international travel, as well as the risk associated with recurrent outbreaks of foodborne illness from commercial food sources, it is important to recognize various syndromes of foodborne illness, including those which may require specific evaluation and management strategies. This article reviews a number of the most common causes of foodborne illness, as well as several less common pathogens with the potential for causing significant morbidity and mortality if not promptly identified and treated.

ReviewCommunity-associated methicillin-resistant Staphylococcus aureus.
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has emerged over the last decade across the United States and the world, becoming a major pathogen in many types of community-acquired infections. Although most commonly associated with minor skin and soft tissue infections, such as furuncles, CA-MRSA also can cause necrotizing fasciitis, pyomyositis, osteoarticular infections, and community-acquired pneumonia. This article discusses the epidemiology, diagnosis, and management of these infections from the perspective of the emergency physician.
