Review Case Reports
Acute airway compromise after brief exposure to a Dieffenbachia plant.
Dieffenbachia is a common domestic plant. Oral contact with the plant usually is associated with minimal consequences. However, chewing on the stem or the leaf of the Dieffenbachia can result in painful oropharyngeal edema and the inability to speak or handle secretions. ⋯ The exact mechanism of edema is not known; therefore, methods of treatment are variable. We recommend caution when presented with a patient exposed to Dieffenbachia. Even the patient who initially seems stable may have an airway that will quickly deteriorate.

Gatherings of large numbers of people at concerts, sporting events, and other occasions lead to an assembled population with a potential for a wide variety of illnesses and injuries. The collection of large numbers of people in a single location has led some authors to recommend the placement of resuscitation equipment or other medical services in close proximity to these activities. These recommendations not withstanding, data on the frequency of critical illness at mass gatherings (a group exceeding 1000 persons) are difficult to ascertain. ⋯ Of those referred to the ED, 50 (38.7%) patients were transported by ambulance and only 17.4% were admitted to telemetry, with none admitted to an ICU. It is concluded that critical illness at mass gatherings is infrequent, as seen in this study, with very few being admitted to telemetry and none to an ICU. Careful consideration of cost-benefit should occur when determining allocation of resources for these activities.

Benzodiazepines, although not listed in the American Heart Association's guidelines for the treatment of chest pain, are often used to provide symptomatic relief to patients who experience chest pain. To investigate the utility of benzodiazepines in the treatment of chest pain, the pharmacologic actions and cardiovascular effects of benzodiazepines were reviewed. In addition, a literature search regarding the use of benzodiazepines to treat patients with chest pain was conducted. ⋯ Benzodiazepines are safe and well tolerated when administered alone or in combination with other medications. Moreover, the risk of dependence is minimal when benzodiazepines are prescribed on a short-term basis. Further study of benzodiazepines in the treatment of acute chest pain is needed to confirm these favorable actions and better define their use in the acute medical setting.

Few studies have evaluated the necessity of immediate stress testing after observation for chest pain. The purpose of this study was to assess the safety of outpatient stress testing after discharge from a chest pain unit. We hypothesized that discharge from a chest pain unit before stress testing is associated with a low rate of short-term adverse outcomes. ⋯ Nine patients (2.6%) were admitted to the hospital and 10 (2.9%) were readmitted to the observation unit for chest pain. We conclude that patients who have negative serial electrocardiograms and enzyme testing in a chest pain unit are at low risk for short-term cardiac events. Appropriately selected patients may be discharged for subsequent outpatient testing.

The objective of the study was to measure the utilization and diagnostic value of tests used in the Emergency Department (ED) on patients with undifferentiated non-traumatic abdominal or flank pain. Specific goals were to measure how often these tests led to changes in diagnosis or disposition, which tests were most commonly used, and which tests providers considered most helpful. We conducted a pilot single-center, prospective descriptive study, enrolling all eligible adult patients who presented to our ED with non-traumatic abdominal or flank pain during defined hours of our intake period. ⋯ In conclusion, among ED patients who presented with non-traumatic abdominal or flank pain to one academic center, the pre-test most likely diagnosis and disposition were changed based on the ED evaluation in over one-third of subjects. Almost all received blood tests and two-thirds received one or more imaging studies. Based on providers' subjective opinions, the most valuable tests were the abdomino/pelvic CT scan and the urinalysis.
