Case ReportsEfficacy of glutathione therapy in relieving dyspnea associated with COVID-19 pneumonia: A report of 2 cases.
Infection with COVID-19 potentially can result in severe outcomes and death from "cytokine storm syndrome", resulting in novel coronavirus pneumonia (NCP) with severe dyspnea, acute respiratory distress syndrome (ARDS), fulminant myocarditis and multiorgan dysfunction with or without disseminated intravascular coagulation. No published treatment to date has been shown to adequately control the inflammation and respiratory symptoms associated with COVID-19, apart from oxygen therapy and assisted ventilation. We evaluated the effects of using high dose oral and/or IV glutathione in the treatment of 2 patients with dyspnea secondary to COVID-19 pneumonia. ⋯ Oral and IV glutathione, glutathione precursors (N-acetyl-cysteine) and alpha lipoic acid may represent a novel treatment approach for blocking NF-κB and addressing "cytokine storm syndrome" and respiratory distress in patients with COVID-19 pneumonia.

Case ReportsProne positioning to improve oxygenation and relieve respiratory symptoms in awake, spontaneously breathing non-intubated patients with COVID-19 pneumonia.
Emergency departments are facing an unprecedented challenge in dealing with patients who have coronavirus disease 2019 (COVID-19). The massive number of cases evolving to respiratory failure are leading to a rapid depletion of medical resources such as respiratory support equipment, which is more critical in low- and middle-income countries. In this context, any therapeutic and oxygenation support strategy that conserves medical resources should be welcomed. ⋯ Self-proning can be used in the management of selected patients with COVID-19 pneumonia. Here, we describe our experience with two COVID-19-positive patients who were admitted with respiratory failure. The patients were successfully managed with self-proning and noninvasive oxygenation without the need for intubation.

Case ReportsDetection of SARS-CoV-2 by bronchoscopy after negative nasopharyngeal testing: Stay vigilant for COVID-19.
Real-time polymerase chain reaction (RT-PCR) detection of severe acute respiratory syndrome coronavirus (SARS-CoV-2) is required for diagnosis of coronavirus disease 2019 (COVID-19). Sensitivity of RT-PCR nasopharyngeal (NP) testing is presumed to be high, but there is no gold standard against which this has been determined. The objective was to determine whether lower respiratory tract infection (LRTI), detected in bronchoalveolar lavage fluid (BALF), occurs in the absence of upper respiratory tract infection with clinical testing of both specimen types. ⋯ These data demonstrate that SARS-CoV-2 LRTI occurs in the presence of negative NP testing. NP testing may underestimate the prevalence of COVID-19 and has implications for spread of SARS-CoV2 in the community and healthcare setting.

Case ReportsSARS-CoV2 induced pulmonary embolism and complications from anticoagulation.
Coronavirus disease (COVID-19) pandemic has rapidly spread around the world. As new complications associated with the virus become more apparent, concerns in the medical community continue to grow. One of the more commonly encountered and more troubling complications in critically ill patients has been hypercoagulable state and subsequent thrombotic events. ⋯ Literature review suggests that pulmonary clot burden in COVID-19 patients could be due to pulmonary thrombus rather than pulmonary embolism and is triggered by profuse vascular damage and severe inflammatory response. Literature review also proposes changes to the diagnostic work up in COVID-19 patients, such as earlier screening for pulmonary embolism in critically ill. In addition, rare and severe complications of current anticoagulation therapy is illustrated and discussed through one of the cases presented.

Case ReportsConfirmed E-cigarette or vaping product use associated lung injury (EVALI) with lung biopsy; A case report and literature review.
E-cigarette or vaping has become an increasingly popular alternative to smoking tobacco. In September 2019 multiple cases of confirmed E-cigarette or vaping product use associated lung injury were published. However, there is limited knowledge regarding the pathologic mechanism of this condition. ⋯ The underlying pathophysiological mechanism in E-cigarette or vaping product use associated lung injury is most likely acute lung injury related to direct inhalant-mediated parenchymal inflammation.
