You are presented with a paragraph from a COVID-19 literature. Classify the topics of this piece of text by choosing from the following categories:

- Epidemic Forecasting: The content relates to predictions about the spread of COVID-19.
- Treatment: The paragraph discusses therapeutic methods or medication for COVID-19.
- Prevention: The content covers measures to prevent the spread of COVID-19.
- Mechanism: The paragraph explains the biological mechanisms of the virus.
- Case Report: The content is a report of a COVID-19 case.
- Transmission: The paragraph discusses how COVID-19 is transmitted.
- Diagnosis: The content is about diagnosing COVID-19 in individuals.

Your classification should be provided as an element within a JSON array.

Include all applicable topics within the array. Your output should be a valid JSON array, and no additional text should be included in your response.

Article:

Cases of pneumothorax/pneumomediastinum have been reported in patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2); however, the time to onset and hospital stay have rarely been studied. Coronavirus disease 2019 (COVID-19) patients with these complications are described to determine the time to onset, associated comorbidities, and location and duration of pneumothorax. A search in PubMed yielded simple frequencies and a bivariate analysis of deaths. There were 113 confirmed cases in 67 articles. The median time from the date of hospital admission to the presence of pneumothorax was 8 days. Right hemithorax was the most frequent form of pneumothorax. Almost half of the patients required intubation for invasive mechanical ventilation. Although the frequency of this phenomenon was not high among hospitalized patients with confirmed SARS-CoV-2, it was high among those who developed acute respiratory distress syndrome (ARDS). This study contributes to the literature because it presents a large number of patients who developed pneumothorax after admission, which was characterized by clinical deterioration (dyspnea, tachypnea, pleuritic chest pain, and subcutaneous emphysema) and low oxygen saturation levels. Pneumothorax/pneumomediastinum is recommended as a differential diagnosis, even without considering the presence of chronic pulmonary comorbidities or invasive mechanical ventilation.
