COVID-19 Viral Load in the Severity of and Recovery From Olfactory and Gustatory Dysfunction.

OBJECTIVES/HYPOTHESIS: This study investigated olfactory and gustatory dysfunction in the 2020 novel coronavirus disease (COVID-19) patients, and their correlations with viral load evaluation. STUDY DESIGN: Prospective cross-sectional cohort study. METHODS: One hundred forty-three symptomatic patients being screened for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were invited to participate. The clinical data of 83 confirmed COVID-19 subjects were collected, with 60 patients who were symptomatic but negative for COVID-19 recruited as controls. The prevalence and severity of and recovery time for olfactory and gustatory dysfunction, and cycle threshold (Ct) values from a SARS-CoV-2 polymerase chain reaction assay of nasopharyngeal and deep throat swabs were collected. Their correlations with Ct values were reported. RESULTS: Thirty-nine (47.0%) and 36 (43.4%) COVID-19 patients reported olfactory and gustatory dysfunction, respectively. The results of one-way analysis of variance did not show statistically significant relationships between the Ct values and severity of olfactory and gustatory dysfunction (P = .780 and P = .121, respectively). Among the COVID-19 patients who reported smell and taste loss, 28/39 (71.8%) and 30/36 (83.3%) experienced complete recovery, respectively. The mean recovery time was 10.3 ± 8.1 days for olfactory dysfunction and 9.5 ± 6.8 days for gustatory dysfunction. The recovery time was not correlated with the Ct values (Pearson correlation coefficient, smell: -0.008, P = .968; taste: -0.015, P = .940). CONCLUSIONS: There is a high prevalence of olfactory and gustatory dysfunction in COVID-19. However, the severity of and recovery from these symptoms have no correlations with the viral load of SARS-CoV-2. LEVEL OF EVIDENCE: 4 Laryngoscope, 130:2680-2685, 2020.

Mitigation of head and neck cancer service disruption during COVID-19 in Hong Kong through telehealth and multi-institutional collaboration.

The 2019 novel coronavirus disease (COVID-19) pandemic has been spreading worldwide at an alarming rate. Health-care workers have been confronted with the challenge of not only treating patients with the virus, but also managing the disruption of health-care services caused by COVID-19. In anticipation of outbreak, clinic sessions and operation theater lists have been actively cut back since February 2020 to reduce hospital admissions and clinic attendances. This has severely disrupted health-care services, leading to accumulating clinic caseload and substantial delays for operations. The head and neck cancer service has been faced with the difficult task of managing the balance between infection risk to health-care providers and the risk of disease progression from prolonged waiting times. We share our experience in Hong Kong on the mitigation of head and neck cancer service disruption through telehealth and multi-institution collaboration.

Pearls of experience for safe and efficient hospital practices in otorhinolaryngology-head and neck surgery in Hong Kong during the 2019 novel coronavirus disease (COVID-19) pandemic

The 2019 novel coronavirus disease (COVID-19) epidemic originated in Wuhan, China and spread rapidly worldwide, leading the World Health Organization to declare an official global COVID-19 pandemic in March 2020. In Hong Kong, clinicians and other healthcare personnel collaborated closely to combat the outbreak of COVID-19 and minimize the cross-transmission of disease among hospital staff members. In the field of otorhinolaryngology-head and neck surgery (OHNS) and its various subspecialties, contingency plans were required for patient bookings in outpatient clinics, surgeries in operating rooms, protocols in wards and other services. Infected patients may shed severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) particles into their environments via body secretions. Therefore, otolaryngologists and other healthcare personnel in this specialty face a high risk of contracting COVID-19 and must remain vigilant when performing examinations and procedures involving the nose and throat. In this article, we share our experiences of the planning and logistics undertaken to provide safe and efficient OHNS practices over the last 2 months, during the COVID-19 pandemic. We hope that our experiences will serve as pearls for otolaryngologists and other healthcare personnel working in institutes that serve large numbers of patients every day, particularly with regard to the sharing of clinical and administrative tasks during the COVID-19 pandemic.
