Emergency patient presentations with febrile neutropenia are a heterogeneous group. A small minority of these patients proceed to develop significant medical complications. Risk stratification using scores, such as the Multinational Association for Supportive Care in Cancer score, have been advocated to identify patients who are at low risk of adverse outcome suitable for treatment on an ambulatory care pathway. ⋯ Outpatient ambulatory care for emergency patients with low-risk febrile neutropenia can be delivered in a safe and effective fashion. Collaboration between acute care physicians and oncologists is required to develop local models based on national guidelines to facilitate individualised care for emergency oncology patients.

Direct current cardioversion is a common management option for termination of tachydysrhythmias, including atrial fibrillation and atrial flutter. It is generally safe and effective with infrequent reporting of side effects. Pulmonary edema is a rare complication with reported incidence of 1-3% and mortality of 18%. Our literature search did not reveal any reported cases of postcardioversion pulmonary edema in the emergency medicine literature. ⋯ We report a case of an 80-year-old woman with a history of atypical atrial flutter on warfarin, paroxysmal atrial fibrillation, and rheumatic mitral valve disease who presented with shortness of breath 12 h after transesophageal echocardiography and subsequent direct current cardioversion with reversion to sinus rhythm. She was found to be in acute pulmonary edema. She was placed on noninvasive ventilation and diuresis with eventual symptom resolution. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Postcardioversion pulmonary edema is a rare complication that may occur after reversion to sinus rhythm. Emergency physicians should be cognizant of patients, especially those with underlying structural heart disease, who present with dyspnea after a recent cardioversion procedure or after cardioversion in the emergency department. Patients cardioverted in the emergency department may be observed for around 3 h and counseled on the development of respiratory symptoms.

Case Reports
New-Onset Seizure in Patient Medicated With Bupropion for Smoking Cessation: A Case Report.
Bupropion is a pharmacologic agent approved by the U.S. Food and Drug Administration as an antidepressant and to support smoking cessation. Because reduction of seizure threshold is a rare but serious side effect of bupropion, its use in patients with a known history of seizures is contraindicated. We report a patient without seizure risk factors who presented to the emergency department (ED) with new-onset seizures secondary to bupropion use. ⋯ A 66-year-old female presented to the ED by emergency medical services with altered mental status. She was determined to be postictal after a witnessed new-onset seizure 4 days after starting bupropion for smoking cessation. She had no personal or family history of seizure disorders, although her medication list raised suspicion that recent discontinuation of alprazolam may have contributed to a reduced seizure threshold. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: New-onset seizures secondary to bupropion use are less likely in patients with no personal or family history of seizure disorders. Emergency medicine clinicians should be aware, however, of the seizure risk associated with bupropion regardless of personal risk factors. Discontinuation of bupropion should be considered if determined to be a contributor to seizures.

Clinical scores have been proposed to stratify the risk of pulmonary thromboembolism (PTE), although this approach suffers a low specificity and the unavoidable need for computed tomography pulmonary angiography (CTPA) scans. ⋯ Current clinical stratification tools for PTE are characterized by low specificity, leading to an overuse of CTPA. mWells', rather than Wells', score showed a better predictive performance of PTE detection. Our results suggest that current diagnostic pathway for PTE may be improved by simple adjustments (i.e., mWells') of clinical prediction scores.

Observational Study
Novel Use of a Gas Analyzer Can Reliably Predict the Arterial Oxygen among Emergency Department Patients Undergoing Rapid Sequence Intubation.
To our knowledge, no study has assessed the correlation of fraction of inspired oxygen (FiO2) and end-tidal oxygen (EtO2) values obtained from a gas analyzer during the preoxygenation period of rapid sequence intubation (RSI) to predict partial pressure of oxygen (PaO2) among patients requiring intubation in the emergency department (ED). ⋯ Among ED patients undergoing RSI, the use of a gas analyzer to measure EtO2 and FiO2 can provide a reliable measure of the minimal PaO2 at the time of induction during the RSI phase of preoxygenation.
