The objective of this study is to determine the rate of intra-abdominal injury (IAI) in adults with blunt abdominal trauma after a normal abdominal computed tomographic (CT) scan. We hypothesize that the risk of subsequent IAI is so low that hospital admission and observation for possible IAI are unnecessary. ⋯ Adult patients with blunt torso trauma and normal abdominal CT scans are at low risk for subsequently identified IAI. Thus, hospitalization for evaluation of possible IAI after a normal abdominal CT scan is unnecessary in most cases.

With recent advances in radiologic diagnostic procedures, the use of diagnostic peritoneal lavage (DPL) has markedly declined. In this study, we reviewed data to reevaluate the role of DPL in the diagnosis of hollow organ perforation in patients with blunt abdominal trauma. ⋯ For patients with blunt abdominal trauma and hemoperitoneum who plan to receive nonoperative management, DPL is still a useful tool to exclude hollow organ perforation that is undetected by CT.

Our objective was to determine if implementing a standard lights and sirens (L&S) protocol would reduce their use and if this had any effect on patient disposition. ⋯ Our protocol significantly reduced the use of L&S. Judicious use of L&S has significant implications for transport safety. By allowing for selective transport with L&S usage, we observed no impact in patient disposition.

Case Reports
Successful electrical cardioversion in a massive concentric hypertrophic cardiomyopathy with atrial fibrillation.
A 59-year-old man with a known history of nonobstructive hypertrophic cardiomyopathy and chronic atrial fibrillation was admitted to our clinic with weakness, palpitation, and exertional dyspnea. Electrocardiogram showed atrial fibrillation with high ventricular rate (120 beats per minute), intraventricular conduction delay, and left ventricular (LV) hypertrophy with ST-segment depression and inverted T waves. A transthoracic echocardiogram showed massive LV concentric hypertrophy. ⋯ His control Doppler echocardiogram revealed peak systolic resting gradient of 54 mm Hg, with an increase to 84 mm Hg at Valsalva maneuver at the LV outflow. Cardiac magnetic resonance showed concentric LV hypertrophy with a 35-mm thickness in diastole, mild scar tissue in LV anterior wall midapical segments, and right ventricle wall thickness with a 10 mm in diastole. There was no bradycardia or tachycardia in 24-hour Holter and exercise electrocardiographic testing.
