Characteristics and clinical outcomes of COVID-19 patients with pulmonary disorders: A single-center, retrospective observational study.

Introduction: Mortality rates and clinical characteristics of patients with coronavirus disease 2019 (COVID-19) admitted to the intensive care unit (ICU) vary significantly.

Objectives: To describe the data of patients with pulmonary comorbidities who were admitted to the ICU with COVID-19 in Qatar in terms of demographic characteristics, coexisting conditions, imaging findings, and outcomes.

Methods: We conducted a retrospective study of the outcomes with regard to mortality and requirement of invasive ventilation, demographic characteristics, coexisting conditions, secondary infections, and imaging findings for critical care patients with COVID-19 in Qatar who had pulmonary comorbidities between March and June 2020.

Spontaneous pneumomediastinum mimicking acute pericarditis.

ST elevations on electrocardiogram (ECG) have a broad differential diagnosis that can vary from benign to more ominous pathologies. These include early repolarization, coronary vasospasm, acute pericarditis, ST-elevation myocardial infarction, ventricular aneurysms, and dissecting aneurysm of the aorta reaching the pericardium. ST-segment changes may also provide a clue to the presence of spontaneous pneumomediastinum (SPM).
