Case Reports
Streptococcus pneumoniae-induced purpura fulminans in a woman with functional asplenia.
Purpura fulminans is a rare complication of septic shock, often associated with Streptococcus pneumoniae. Patients with anatomic or functional asplenia are at increased risk for infection because of impairment of their ability to defend against encapsulated pathogens. ⋯ The clinical presentation, diagnosis, and management of purpura fulminans are reviewed. Purpura fulminans is a rare condition that requires early diagnosis and aggressive management by emergency physicians.

Observational Study
Drowning: an overlooked cause of out-of-hospital cardiac arrest in Canada.
Drowning is a major public health concern, yet little is known about the characteristics of drowning patients. The objectives of this study were to describe the demographic and clinical characteristics of out-of-hospital cardiac arrest (OHCA) attributed to drowning in Ontario and to compare the characteristics of OHCA attributed to drowning to those of presumed cardiac etiology. ⋯ Significant differences exist between OHCA of drowning and presumed cardiac etiologies. Most drownings are unwitnessed, occur in public locations, and present with nonshockable initial rhythms, suggesting that treatment should focus on bystander CPR. Future initiatives should focus on strategies to improve supervision in targeted locations and greater emphasis on bystander-initiated CPR, both of which may reduce drowning mortality.

Low socioeconomic status (SES) is associated with adverse health outcomes. Possible explanations include differences in health status, access to health care, and care provided by clinicians. We sought to determine whether SES is associated with computed tomography (CT) use in the emergency department (ED). ⋯ Lowest SES ED patients were less likely to receive CT scans overall and in headache and abdominal pain subgroups. No difference was seen among complex abdominal pain patients, suggesting that as clinical indications for the test become more clearcut, use across SES quintiles differs less.

Minor head trauma in young children is a major cause of emergency department visits. Conflicting guidelines exist regarding radiologic evaluation in such cases. ⋯ Canadian emergency physicians have a wide variation in skull radiography ordering in young children with minor head trauma. This variation, along with the need expressed by physicians, suggests that further research to develop a clinical decision rule is warranted.
