Does phenotypic expression of bitter taste receptor T2R38 show association with COVID-19 severity? Introduction: SARS-CoV-2 has been identified as the pathogen causing the outbreak of Coronavirus Disease 2019(COVID-19) commencing in Wuhan, China, in December 2019. Multiple reports have shown subjective loss of taste and smell as an early and hallmark symptom for COVID-19. Method: A retrospective study was performed in our clinical practice during July 2020 on patients positive for SARS-CoV-2 via PCR. All patients were categorized into 3 groups (supertasters, tasters, & nontasters) via taste sensitivity to phenylthiocarbamide, thiourea, and sodium benzoate with taste strip testing. The results of the taste strip tests were correlated with clinical course. Results: 100 patients (mean 51 [Range 24-82] years [...]

Nasal Endoscopy During COVID-19 Mohamed A. Taha, MD1,2, Christian A. Hall, MD1,3, and Henry P. Barham, MD1,3 Nasal endoscopy is considered the standard of care for appropriate and cost-effective diagnosis and management of sinonasal diseases as it allows for direct visualization of inflammatory, infectious, neoplastic and other complex pathologies. Kuhn reviewed the importance of endoscopy, stating that it aids in direct evaluation of mucosa.1 Endoscopy allows for tissue sampling and staging of severity of sinonasal disease. It allows for direct evaluation of structural changes such as scarring, resected turbinates, partially resected uncinate processes, residual ethmoid cells, posterior fontanel antrostomies, not connected to the maxillary sinus ostium, and sphenoid sinus stenosis. Other applications mentioned by Kuhn include culturing [...]
