The incidence of ceftriaxone-related hypersensitivity skin reactions is between 1% and 3%, whereas anaphylaxis is rare. To the best of our knowledge, the following case is the first report of asystole after the administration of single-dose ceftriaxone. A 55-year-old man was admitted to our emergency department because of high fever, abdominal pain, dysuria, and weakness. ⋯ The time of onset was suggestive of ceftriaxone-induced anaphylaxis. The patient was discharged in good clinical condition on the 10th day of admission. Emergency physicians should be mindful of the possibility of anaphylaxis and asystole that could occur with the first dose of ceftriaxone and should also make sure to offer receiving detailed informed patient consent, too.

The purpose of our study was to evaluate interobserver variability between the radiologist and emergency physician in detecting blunt liver trauma by conventional and contrast-enhanced ultrasound (US) (CEUS). ⋯ Contrast-enhanced US may permit a more accurate diagnosis for liver trauma than conventional US by both the radiologist and emergency physician. Contrast-enhanced US may also reduce interobserver variability for this diagnosis.

This study aims to evaluate clinical values and determine the function of a pediatric observation unit (POU) as an alternative to inpatient unit admission for children with newly onset seizures. ⋯ The POU may be an alternative to immediate admission in selected cases of first seizures. Related information such as age, use of anticonvulsants in the ED, serum C-reactive protein value, and clinical diagnosis of febrile seizure are important factors for determining whether pediatric patients with first seizure attack should be admitted or discharged.

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.
