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 ReportsAcute Respiratory Distress Syndrome in a pregnant patient with COVID-19 improved after delivery: A case report and brief review.
Acute Respiratory Distress Syndrome (ARDS) can frequently occur as a complication of Coronavirus Disease 19 (COVID-19). As the number of COVID-19 cases increases around the world, it is inevitable that COVID-19 and ARDS will complicate some pregnancies. Currently, there is scant data to guide decision-making on the timing of delivery for these patients. We present the case of a 41-year-old patient with severe ARDS from COVID-19 who was also 32 weeks pregnant, whose respiratory status improved dramatically after delivery.

Case ReportsLate presentation of lung adenocarcinoma in a stable solitary pulmonary nodule: A case presentation and review of the literature.
A 67-year-old patient has been followed by our pulmonary clinic for Chronic obstructive pulmonary disease (COPD) and a stable pulmonary nodule. Solitary pulmonary nodule (SPN) was detected on the lung cancer screening by low dose computed tomography (CT) scan of the chest. It remained stable on repeat CT scan at 6, 12 and 24-months interval. ⋯ The patient then underwent right upper lobectomy followed by chemoradiation therapy. Current guidelines do not recommend follow up for a solitary pulmonary nodules less than 6 mm nodule if it remains stable for 12-24 months. Our case report of the late presentation of lung adenocarcinoma in a stable solitary pulmonary nodule suggests the need to exercise increased caution in the management of incidental pulmonary nodules.

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.
