Extracorporeal Life Support for Respiratory Failure in Patients With Electronic Cigarette or Vaping Product Use-Associated Lung Injury.

OBJECTIVES: Electronic cigarette or vaping product use-associated lung injury is a clinical entity that can lead to respiratory failure and death. Despite the severity of electronic cigarette or vaping product use-associated lung injury, the role of extracorporeal life support in its management remains unclear. Our objective was to describe the clinical characteristics and outcomes of patients with electronic cigarette or vaping product use-associated lung injury who received extracorporeal life support. DESIGN: We performed a retrospective review of records of electronic cigarette or vaping product use-associated lung injury patients who received extracorporeal life support. Standardized data were collected via direct contact with extracorporeal life support centers. Data regarding presentation, ventilatory management, extracorporeal life support details, and outcome were analyzed. SETTING: This was a multi-institutional, international case series with patients from 10 different institutions in three different countries. PATIENTS: Patients who met criteria for confirmed electronic cigarette or vaping product use-associated lung injury (based on previously reported diagnostic criteria) and were placed on extracorporeal life support were included. Patients were identified via literature review and by direct contact with extracorporeal life support centers. MEASUREMENTS AND MAIN RESULTS: Data were collected for 14 patients ranging from 16 to 45 years old. All had confirmed vape use within 3 months of presentation. Nicotine was the most commonly used vaping product. All patients had respiratory symptoms and radiographic evidence of bilateral pulmonary opacities. IV antibiotics and corticosteroids were universally initiated. Patients were intubated for 1.9 days (range, 0-6) prior to extracorporeal life support initiation. Poor oxygenation and ventilation were the most common indications for extracorporeal life support. Five patients showed evidence of ventricular dysfunction on echocardiography. Thirteen patients (93%) were placed on venovenous extracorporeal life support, and one patient required multiple rounds of extracorporeal life support. Total extracorporeal life support duration ranged from 2 to 37 days. Thirteen patients survived to hospital discharge; one patient died of septic shock. CONCLUSIONS: Electronic cigarette or vaping product use-associated lung injury can cause refractory respiratory failure and hypoxemia. These data suggest that venovenous extracorporeal life support can be an effective treatment option for profound, refractory respiratory failure secondary to electronic cigarette or vaping product use-associated lung injury.

Extrapulmonary Gastrointestinal Presentation of Coronavirus (COVID-19): A Case Report and Review of Literature.

Coronavirus disease 2019 (COVID-19) is currently the causative agent for a global health emergency and is predominantly associated with respiratory symptoms. In this case, a patient presented to the emergency department with gastrointestinal symptomatology without associated respiratory findings and was subsequently diagnosed with COVID-19 based on incidental findings from an abdominal computed tomography (CT) study. Given the patient's lack of respiratory symptoms, diagnosis and treatment were ultimately delayed. During this global health crisis, an improved understanding of the various presentations of COVID-19 is paramount in an effort to initiate immediate treatment and prevent further transmission.

Orbital cellulitis, sinusitis and intracranial abnormalities in two adolescents with COVID-19.

We review two cases of adolescents with orbital cellulitis, sinusitis and SARS- CoV-2 infection presenting to emergency departments within a 24 hour period. SARS-CoV-2 samples obtained within 24 hours were positive, supporting prior infection despite relatively limited early symptoms of COVID-19. Unusual clinical and radiographic characteristics included hemorrhagic abscess with blood of varying age in the first, intracranial epidural abscess in the second, radiographic signal consistent with hemorrhagic or thrombotic phenomena, retro-maxillary antral fat changes, and meningeal enhancement or extension in both cases. Radiographic findings thereby mimic fungal infection, although final cultures and ancillary investigation for allergic and invasive fungal disease have remained negative. These cases highlight two unusual orbital presentations of cellulitis occurring in the context of SARS-CoV-2 co-infection.

Early Diagnosis of COVID-19 on Non-Chest CT Studies in the Emergency Setting: A Case Series and Review of the Literature.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel strain of coronavirus that has spread throughout the globe causing coronavirus disease 2019 (COVID-19). As the number of cases rises in the United States (US), it has become more imperative to detect COVID-19 at its earliest radiologic stage to decrease community transmission. In this case series, we discuss five patients who presented with non-respiratory-related symptoms and underwent non-chest CT imaging, such as abdominal and neck CT, with a portion of the lungs visualized in each respective study. Imaging findings of COVID-19 include basilar and peripherally predominant pulmonary parenchymal ground-glass opacities. All five of our patients had findings suggestive of COVID-19 that prompted the radiologist to suggest testing for the disease. Subsequently, four of the five patients tested positive for COVID-19, and one of them was presumed to have the diagnosis based on clinical and imaging findings.
