Management of massive pulmonary embolism in patients with hemodynamic instability encompasses the use of fibrinolytics. Use of fibrinolytic therapy is currently recommended in this patient population by ACCP, AHA, and EHA if treatment benefit outweighs the risk of bleeding. There is currently no data challenging or exploring the risk of using fibrinolytic therapy for the management of massive PE in patients with a history of intracranial hemorrhage. ⋯ In patients with a history of intracranial hemorrhage, catheter guided fibrinolytic and thrombectomy may be effective treatment options of massive pulmonary embolism.

While primarily a respiratory illness, infection with the novel coronavirus (COVID-19) is associated with pathologic changes in coagulation, characterized by both thromboembolic and bleeding events. We present the case of a 22-year-old female diagnosed with renal angiomyolipoma (AML) rupture 2 weeks after COVID-19 infection, ultimately requiring admission for hemorrhage control via endovascular embolization. Emergency medicine physicians should maintain a high index of suspicion for renal AML rupture and other spontaneous bleeding events in patients with recent COVID-19 infection due to a possible correlation between the two.

Case Reports
Central neurogenic hyperventilation secondary to suspected metastatic renal cell carcinoma.
Central neurogenic hyperventilation (CNH) is a neurogenic disorder rarely described within Emergency Medicine literature. CNH is a primary cause of hyperventilation, most commonly due to primary central nervous system neoplasms. Patient presentation varies based on the underlying cause, and may present with a sole chief complaint of dyspnea. ⋯ While the cause of the patient's hemorrhage was not elucidated, given the patient's widely metastatic disease, it was presumed to be secondary to metastasis. Our case highlights both a unique cause of a rare disorder of hyperventilation, and a diagnostic challenge to the emergency medicine provider. It is important to consider central causes of hyperventilation in patients with dyspnea and neurologic symptoms.

The primary purpose of this study was to evaluate trends in ambulance utilization and costs among Medicare beneficiaries from 2007 to 2018. Community characteristics associated with ambulance use and costs are also explored. ⋯ Numerous policy solutions have been proposed to address growing ambulance costs in the Medicare program. While ambulance transports and costs continue to increase, a bend in the ambulance cost curve is detected suggesting that one or more policies altered Medicare ambulance costs, although utilization has continued to grow linearly. Ambulance use and costs vary significantly with community-level factors. As policy makers consider how to address growing ambulance use and costs, targeting identified community-level factors associated with greater costs and utilization, and their root causes, may offer a targeted approach to addressing current trends.
