The purpose was to compare head kinematics between the Eject Helmet Removal System and manual football helmet removal. ⋯ Although the Eject system created more motion at the head, removing a helmet manually resulted in more sudden perturbations as identified by resultant velocity and acceleration of the head. The implications of these findings relate to the care of all cervical spine-injured patients in emergency medical settings, particularly in scenarios where helmet removal is necessary.

Cardiomegaly is a common but nonspecific finding in the emergency department. The etiology may be explained by left ventricular dilation, biventricular dilation, right ventricular dilation, or pericardial abnormalities, or it may be found to be spurious on the echocardiogram. Rarely, isolated abnormalities of the atrium, particularly the left atrium, may cause abnormalities on the chest radiograph but will not cause true cardiomegaly. ⋯ The diagnosis of a rare huge left atrial aneurysm was finally established by multidetector-row computed tomography, which had been seldom used as a diagnostic tool in the past. Patients with this cardiac anomaly usually are asymptomatic until the second or third decade of life, when the aneurysms can reach remarkable sizes and are often complicated with atrial tachyarrhythmia or thromboembolic events. Early surgical intervention is advised even in asymptomatic patients to prevent the occurrence of myocardial dysfunction, atrial fibrillation, and systemic embolism.

Cauda equina syndrome (CES) is an uncommon entity. Symptoms include bowel and bladder dysfunction, saddle anesthesia, and varying degrees of lower limb motor and sensory disturbances. ⋯ There is little in literature regarding abdominal pain as a significant feature of the initial presentation of CES. We present the case of a 32-year-old woman with CES who presented to the emergency department with gradually worsening lower abdominal pain.

Bedside ultrasound is being increasingly used by emergency physicians (EPs) for the differentiation of acute dyspnea in critically ill patients. Lung ultrasound is emerging as a highly sensitive tool in diagnosing alveolar interstitial edema with the presence of diffuse “B-lines” arising from the pleural line. However, when used independently, lung ultrasound is unable to differentiate between cardiogenic and noncardiogenic causes of pulmonary edema. This case report describes a rapid 3-view or “triple scan” sonographic examination to differentiate acute respiratory distress syndrome (ARDS) from cardiogenic pulmonary edema.
