Stroke is the second common cause of death and the primary cause of early invalidity worldwide. Different from other diseases is the time sensitivity related to stroke. In case of an ischemic event occluding a brain artery, 2000000 neurons die every minute. ⋯ Beyond its diagnostic use, first clinical trials as well as numerous preclinical work demonstrate that ultrasound can be used to accelerate clot lysis (sonothrombolysis) in presence as well as in absence of tissue plasminogen activator. Hence, the use of transcranial ultrasound for diagnosis and possibly treatment of stroke bares the potential to add to current stroke care paradigms significantly. The purpose of this concept article is to describe the opportunities presented by recent advances in transcranial ultrasound to diagnose and potentially treat large vessel embolic stroke in the prehospital environment.

We present a multicenter validation of a modified Manchester Triage System (MTS) flowchart for pediatric patients who present with headache to the emergency department. A prospective observational study was conducted across 5 European pediatric emergency departments. The standard MTS headache flowchart and a modified MTS headache flowchart were tested in the participating centers, and results were compared with triage categories identified by either the physician at the end of the clinical examination or the reference classification matrix (RCM). Fifty-three patients were enrolled in the preimplementation phase and 112 in the postimplementation phase. When compared with physician's triage and RCM, the modified MTS flowchart demonstrated good sensitivity (79% and 70%, respectively), specificity (77% and 76%, respectively), and a high positive likelihood ratio (9.14 and 16.75, respectively) for the identification of low-risk children. ⋯ Our modified headache flowchart is safe and reliable in pediatric emergency settings, especially for lower classes of urgency.

Approximately 7% of the US population abuses or is dependent on alcohol. Patients with alcohol disorders often seek medical attention in Emergency Departments (EDs) for complications directly related to alcohol use or due to other medical issues associated with alcohol use. ⋯ This article reviews the physiology of alcohol withdrawal as well as the symptoms of this potentially deadly illness for the practicing emergency physician (EP). We provide evidence-based guidelines for the appropriate ED treatment of moderate to severe AWS, including pharmacologic interventions, adjunctive therapies, and disposition of these patients.

The aim of this present study was to compare the diagnostic accuracy and reproducibility of 2 clinical decision rules (the Ottawa Knee Rules [OKR] and Pittsburgh Decision Rules [PDR]) developed for selective use of x-rays in the evaluation of isolated knee trauma. Application of a decision rule leads to a more efficient evaluation of knee injuries and a reduction in health care costs. The diagnostic accuracy and reproducibility are compared in this study. ⋯ The PDR was found to be more specific than the OKR, with equal sensitivity. Interobserver agreement was moderate for the OKR and substantial for the PDR.

To determine whether patients with sickle cell disease (SCD) experience longer wait times to see a physician after arrival to an emergency department (ED) compared to patients with long bone fracture and patients presenting with all other possible conditions (General Patient Sample), and to attempt to disentangle the effects of race and disease status on any observed differences. ⋯ Patients with SCD presenting to an ED for care experience longer wait times than other groups, even after accounting for assigned triage level. The African-American race of the SCD patients, and their status as having SCD itself, both appear to contribute to longer wait times for these patients. These data confirm patient anecdotal reports and are in need of intervention.
