Infected aortic aneurysm is a relatively rare disease with significant morbidity and mortality. Because of its deeper position, patients with infected aortic arch aneurysms may present with only fever and other vague symptoms, such as weakness, fatigue, dizziness, anorexia, and functional decline. It is difficult confirm a diagnosis that is based solely on history or physical examination, and it may only be apparent on imaging studies. ⋯ We present a brief case report of a patient presenting to the emergency department with unexplained fever who was diagnosed with emphysematous salmonella-infected aneurysm of the aortic arch. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Infected aortic arch aneurysm is an extremely unusual disease entity that emergency physicians encounter. Because of the high mortality and morbidity of this catastrophic disease, an infected aortic aneurysm should be considered as a possible diagnosis in patients with persistent fever and vague symptoms without a specific infection focus. To avoid delayed diagnosis, emergency physicians should be aware of infected aortic arch aneurysm.

Post-procedural coronary aneurysms can have high morbidity and mortality. Although found more commonly on ultrasound or computed tomography imaging, if large enough, they may appear on chest x-ray studies. ⋯ We present two cases of coronary artery aneurysm visible on chest x-ray study-one originating from a saphenous vein graft and the other a left anterior descending artery pseudoaneurysm 1 week post heart catheterization. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: It is important for emergency physicians to recognize abnormal chest x-ray studies and to look for post-procedural complications, such as coronary artery aneurysm. Coronary artery aneurysm can be a potentially life-threatening condition requiring prompt recognition and surgical consultation.

Emergency department (ED) clinicians may misdiagnose renal infarction (RI) as urolithiasis because RI is a rare disease with presenting symptoms similar to the symptoms of urolithiasis. However, earlier diagnosis of RI can improve patient prognosis. ⋯ Age ≥ 65 years, atrial fibrillation, current smoking, absence of costovertebral angle tenderness, aspartate aminotransferase level ≥ 27.5 U/L, sodium level < 138.5 mEq/L, and absence of hematuria were predictors that can distinguish between RI and urolithiasis.

Chemotherapy-induced febrile neutropenia (FN) is one of the more common oncological emergencies. Despite evidence in the oncology literature suggesting that low-risk cases of FN can be managed safely at home, most patients with FN who present to the emergency department (ED) are admitted. FN risk stratification methods, such as Multinational Association for Supportive Care in Cancer (MASCC) and Clinical Index of Stable Febrile Neutropenia (CISNE) scores, may be useful when considering patient disposition. We sought to address whether the existing body of literature is adequate to support the use of these methods when treating patients with FN in the ED. ⋯ FN risk stratifications tools, such as MASCC and CISNE scores, are supported by the existing literature and may be included as part of the decision-making process when considering patient disposition.

Is Lateral Decubitus or Upright Positioning Optimal for Lumbar Puncture Success in a Teaching Hospital?
Lumbar puncture is a common procedure performed by emergency physicians and trainees. The optimal patient positioning for lumbar puncture procedures has not been studied adequately. ⋯ Lateral decubitus and upright positioning for emergency lumbar puncture yielded equal success rates in emergency physicians and trainees.
