In 2000, a series of cases of necrotizing fasciitis (NF) among injection users of black tar heroin was observed in our Emergency Department (ED). The description of these cases characterizes the ED presentation of NF, focusing on the sensitivity of physical signs and ED diagnostic tests. All cases of pathologically determined NF in 2000 were prospectively and retrospectively identified and analyzed. ⋯ Thirty-seven percent of blood cultures and 75% of surgical wound cultures were positive, revealing a variety of organisms. Although tachycardia, leukocytosis, and elevated lactate levels are common in NF patients, fever and soft tissue gas are not. Tests and traditional teaching regarding the "classic" findings of NF should be amended to reflect differences seen in the setting of injection drug use with black tar heroin.

Electrocardiographic manifestations: diagnosis of atrioventricular block in the Emergency Department.
Patients with bradycardia are commonly encountered by the Emergency Physician. Of the possible bradydysrhythmias, atrioventricular blocks (AVB) represent a significant portion of these presentations. ⋯ We review the various types of AV block dysrhythmias (1st, 2nd, and 3rd degrees) and their underlying etiologies. This discussion also focuses on the presentation, clinical considerations, management and acute treatment of AVB dysrhythmias in the emergent setting.

Case Reports
Cervical epidural abscess associated with massively elevated erythrocyte sedimentation rate.
We present a case of an elderly woman who presented with neck pain, low-grade fever, bandemia, and a massively elevated erythrocyte sedimentation rate (ESR) who had a cervical epidural abscess. We believe that the selective use of ESR assisted in narrowing the differential diagnosis, as the patient had no neurological deficits and no predisposing factors such as distal infection, immunosuppression, trauma, or recent surgery. Furthermore, in the literature, an elevated ESR is consistently found in patients with epidural abscesses, whereas clinical findings such as fever, leukocytosis, and neurological deficits are only variably present.

This article reviews the empirical literature on patient satisfaction in the Emergency Department (ED). It explores the implications for clinical practice, discusses limitations and weaknesses of the literature, and provides direction for future research. Articles resulting from a comprehensive electronic search were obtained, their references examined, and all other relevant articles not already discovered via the electronic search were acquired and reviewed. ⋯ Promising interventions include: providing information on how the ED functions through visual media, improving ED processes through performance improvement methodologies, and improving the interpersonal skills of providers. Interventions designed to reduce actual waiting times have not been sufficiently studied, but results from several well-designed studies suggest that such a strategy is unlikely to have as great an impact as those targeting perceived waiting times. To advance this area of research, investigators must use: 1) larger, more representative samples; 2) reliable and valid assessment instruments; 3) theory-driven hypothesis testing; and 4) randomized, controlled trials.

This case report illustrates an adult presenting with the simultaneous occurrence of both methemoglobinemia (MetHb) and systemic toxicity from the topical application of local anesthetics while undergoing laser epilation therapy of the legs. The concurrent development of both is considered uncommon in this setting and may have been related to several factors, including her recent previous treatment, increased absorption secondary to abraded skin with the addition of occlusive dressing, and possible alteration of protein binding and drug metabolism due to the use of medications. The clinical manifestations and mechanisms of MetHb and systemic local anesthetic toxicity are discussed.
