Case ReportsMyocardial injury in a patient with severe coronavirus disease: A case report.
Coronavirus disease (COVID-19) can lead to severe disease or death and is characterized by a wide range of mild to severe symptoms. In addition to the lungs, studies have reported the involvement of the stomach, intestine, and angiotensin-converting enzyme 2 receptors in the heart. ⋯ We report the case of a patient with severe COVID-19 who died from an exacerbation of myocardial injury. Clinicians should not only evaluate respiration but also assess the heart by performing a 12-lead ECG, echocardiogram, and myocardial injury marker examination. Together, these tools can help predict which patients will develop severe COVID-19.

Comparative StudyComparative evaluation of nasopharyngeal swab and saliva specimens for the molecular detection of SARS-CoV-2 RNA in Japanese patients with COVID-19.
Considering the issues of shortage of medical resources and the invasiveness and infection risk involved in the collection of nasopharyngeal swab specimens, there is a need for an effective alternative test specimen for SARS-CoV-2 RNA detection. Here, we investigated suitability of saliva as a non-invasively obtained specimen for molecular detection of SARS-CoV-2 RNA in Japanese patients with COVID-19. In total, 28 paired clinical specimens of saliva and nasopharyngeal swabs were collected from 12 patients at various time points after symptom onset. ⋯ Three convalescent patients presented saliva-positive results, whereas their nasopharyngeal swabs were negative at four different time points, suggesting that saliva may be superior to nasopharyngeal swabs in terms of obtaining stable assay result of SARS-CoV-2. In conclusion, our results suggest that saliva can potentially serve as an alternative to nasopharyngeal swabs as a specimen for SARS-CoV-2 rRT-PCR. As saliva can be collected by patients themselves, it may be an effective way to overcome the shortage of personal protective equipment and specimen sampling tools.

Review Case ReportsCorticosteroids as adjunctive therapy in the treatment of coronavirus disease 2019: A report of two cases and literature review.
The effect of systemic corticosteroids on clinical outcomes in patients with coronavirus disease 2019 (COVID-19) remains controversial. While the use of corticosteroids raises concerns regarding delayed viral clearance, secondary infections, and long-term complications that can lead to increased mortality, corticosteroids have the potential to reduce mortality if used appropriately. Herein, we report good outcomes in two patients with COVID-19 who received systemic corticosteroids as adjunctive therapy. ⋯ Despite the prescription of antiviral drugs, their hypoxemia progressed rapidly. However, after the introduction of systemic corticosteroids, their symptoms improved as the fever decreased, and their hypoxemia gradually improved. These results suggest that some patients with COVID-19 may benefit from the appropriate use of systemic corticosteroids as adjunctive therapy.

Effectiveness of personal protective equipment in preventing severe acute respiratory syndrome coronavirus 2 infection among healthcare workers.
Information on the effectiveness of personal protective equipment (PPE) for preventing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among healthcare workers (HCWs), especially among HCWs with frequent contact with patients with SARS-CoV-2, is limited. ⋯ The study provides evidence that appropriate PPE is sufficient to prevent infection amongHCWs. It is necessary to establish a system that provides a stable supply of PPE for HCWs to perform their duties.

Case ReportsSevere olfactory and gustatory dysfunctions in a Japanese pediatric patient with coronavirus disease (COVID-19).
Coronavirus disease (COVID-19) is often characterized by abnormal olfactory and gustatory symptoms in adults; however, detailed studies on pediatric patients with COVID-19 are extremely limited. A 13-year-old Japanese girl presented with fever and cough, and after 2 days, her olfactory and taste sensations suddenly disappeared. A real-time reverse transcriptase-polymerase chain reaction (RT-PCR) test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was performed using a nasopharyngeal swab. ⋯ On the 18th day of illness, SARS-CoV-2 tested negative in the RT-PCR test; simultaneously, the VAS score for smell and taste fully improved to 100 of 100%. On the 77th day of illness, full recovery was confirmed in the Alinamin test (latency, 7 seconds; duration, 82 seconds). In this present case, an improvement in olfactory and gustatory dysfunctions was observed with negative results in RT-PCR test for SARS-CoV-2.
