Acute mountain sickness (AMS) is a benign and self-limiting syndrome but can progress to life-threatening conditions if leave untreated. This study aimed to assess the efficacy of acetazolamide for the prophylaxis of AMS and disclose potential factors that affect the treatment effect of acetazolamide. ⋯ Acetazolamide is effective prophylaxis for the prevention of AMS in doses of 125, 250, and 375 mg/bid. Future investigations should focus on personal characteristics, disclosing the correlation between acetazolamide efficacy and body mass, height, degree of prior acclimatization, individual inborn susceptibility, and history of AMS.

Review Case Reports
COVID-19 and Acute Pulmonary Embolism: A Case Series and Brief Review.
The SARS-CoV-2 virus, or COVID-19, is responsible for the current global pandemic and has resulted in the death of over 400,000 in the United States. Rates of venous thromboembolism have been noted to be much higher in those infected with COVID-19. ⋯ We also briefly describe the pathophysiology and mechanisms for pulmonary embolism in COVID-19. These cases indicate a need to maintain a high index of suspicion for PE in patients with COVID-19, as well as the need to consider occult COVID-19 infection in patients with PE in the right clinical circumstance.

Review Case Reports
Resurgence of Positive qRT-PCR Test Results in Patients Recovered from COVID-19: Case Reports.
Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a newly emerging coronavirus. This virus poses a great threat to human society and has been marked as the third introduction of a highly pathogenic coronavirus into the human population. This is following severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) in the 21st-century. ⋯ Thus, there is an urgent need for more information to understand this new virus. Here we report the detailed clinical characteristics of three cases of COVID-19 convalescents that had repeated positive quantitative reverse transcription-polymerase chain reaction (qRT-PCR) test results for over three months. This may arouse concerns regarding the present quarantine protocol after convalescence and provide a reference for governments to consider when to reopen the community.
