The emergency management of cerebral concussion typically centers on the decision to perform a head computed tomography (CT) scan, which only rarely detects hemorrhagic lesions requiring neurosurgery. The absence of hemorrhage on CT scan often is equated with a lack of brain injury. However, observational studies revealing poor long-term cognitive outcome after concussion suggest that brain injury may be present despite a normal CT scan. ⋯ The authors discuss the strengths and weaknesses of the evidence in each case. These reports make a compelling case for the existence of concussion as a clinically relevant disease with demonstrable neurologic pathology. Areas for future emergency medicine research are suggested.

Previous studies have reported that pain is undertreated in the emergency department (ED), but few physician-dependent risk factors have been identified. In this study, the authors determine whether pain treatment and relief in ED patients are negatively associated with the physician's perception of whether the patient was exaggerating symptoms, and with the patient and physician's perceptions of the interaction between them, as well as whether demographic characteristics were associated with these perceptions. ⋯ The physician's perception of whether a patient was exaggerating symptoms was associated with the patient's ethnic background and with both the physician's and patient's perception of their interaction. These perceptions were negatively associated with the achievement of pain relief and the change in the patient's pain VAS scores, but not with whether a patient was treated with a pain medication.

Comparative Study
The effect of Picture Archiving and Communications Systems on the accuracy of diagnostic interpretation of pediatric emergency physicians.
To compare the accuracy of diagnostic interpretation of radiographs by pediatric emergency physicians (EPs) before and after the introduction of a Picture Archiving and Communications System (PACS). ⋯ Radiograph interpretations by pediatric EPs with digital studies remain as accurate in comparison with assessments performed by using conventional radiographs.

Hyperglycemia after cerebral ischemia exacerbates brain injury and worsens the outcome of stroke patients. The authors sought to examine the effect of glycemic control on mortality after acute stroke. ⋯ Admission hyperglycemia is associated with a worse outcome after stroke than is euglycemia. Normalization of blood glucose during the first 48 hours of hospitalization appears to confer a potent survival benefit in patients with thromboembolic stroke.

To describe the characteristics of nonfatal sledding-related injuries in U.S. children resulting in emergency department (ED) visits in 2001/2002 and to explore the implications of these findings for injury prevention efforts. ⋯ Sledding injuries resulting in ED visits predominantly affect children and are a source of measurable morbidity in this population. An increase in injury prevention efforts for this activity is warranted.
