When to Use Antibiotics in COVID-19: A Proposal Based on Questions.

The COVID-19 pandemic has affected millions of people, including hundreds of deaths. The search for adequate treatments and interventions that influence poor prognostic factors and reduce mortality has led to excessive use of antibiotics based on the possible existence of bacterial co-infection. However, there is no evidence to justify the systematic use of antimicrobials in COVID-19.

Multimodality cardiac imaging in the diagnostic approach to chronic dyspnea: a patient with pericardial lipoma.

Cardiac masses are rare entities that present with a very varied spectrum of manifestations ranging from asymptomatic to severe hemodynamic compromise. They mainly correspond to benign neoplastic lesions; however, other pathologies may occur. The availability of high-definition imaging techniques has increased early detection.

Viral Cardiomyopathies Associated With SARS-CoV-2 Infection.

Context: Since the end of 2019 with the identification of the new coronavirus SARS-CoV-2 and the disease it produces, named COVID-19, various manifestations have been described, initially pulmonary due to acute and severe respiratory syndromes, now systemic manifestations have been described.

Case Report: We report 3 cases of patients with cardiovascular manifestations associated with SARS-CoV-2 infection, highlighting the diagnostic approach and variety of presentation, from acute myocardial infarction, myocarditis, heart failure, shock, arrhythmias to sudden death.

Conclusions: Every day is more frequent to find reports of patients with cardiovascular compromise during COVID-19 affecting the development and prognosis of this disease.

Pneumomediastinum and Pneumothorax Following Non-invasive Respiratory Support in Patients With Severe COVID-19 Disease.

The coronavirus disease-2019 (COVID-19) pandemic led to an increased number of patients with pneumothorax and pneumomediastinum owing to complications attributed to viral pneumonia regardless of the use of mechanical invasive ventilation and the elapsed time of infection. The pathophysiology remains unknown. However, the Macklin effect is shown as the most plausible mechanism along with possible barotrauma secondary to a high-flow nasal cannula and noninvasive mechanical ventilation.
