COVID-19 findings revealed via otolaryngological examination: Findings of a Japan Otorhinolaryngologist Association questionnaire.

Objective: In Japan, many otolaryngologists provide primary care for patients with coronavirus disease 2019 (COVID-19). The purpose of this study was to analyze the characteristics of otorhinolaryngological findings in order to improve COVID-19 diagnostic systems in a primary care setting.

Methods: A total of 351 patients (mean age, 36.

Comparison of electropharmacological effects between terfenadine and its active derivative fexofenadine using a cross-over study in halothane-anesthetized dogs to analyze variability of pharmacodynamic and pharmacokinetic profiles of terfenadine and torsadogenic risk of fexofenadine.

In order to better understand the variability of pharmacodynamic and pharmacokinetic profiles of terfenadine between the previous studies as well as to qualitatively and quantitatively examine the proarrhythmic potential of its major active metabolite fexofenadine in comparison with that of terfenadine, we directly compared their electropharmacological effects with halothane-anesthetized dogs (n = 3). For this purpose, we adopted a cross-over design, which can directly compare the effects of terfenadine and fexofenadine under the identical metabolic condition. Terfenadine in doses of 0.
