Identification of Viruses in Patients With Postviral Olfactory Dysfunction

Abstract: Objective Causative viruses of postviral olfactory dysfunction (PVOD) have not yet been identified. The aim of this study was to investigate causative viruses in patients with PVOD. Study design and methods Nasal discharge was collected from 24 patients with PVOD. We investigated the presence of 10 viruses in nasal discharge and examined the time course, with regard to changes in olfactory dysfunction and nasal obstruction in patients with PVOD, using questionnaires, acoustic rhinometry, and olfactory tests. Results Rhinoviruses were detected in 10 patients by electrophoresis. Rhinoviruses were also confirmed in four patients by nucleotide sequences. Viral serotypes were identified to be human rhinovirus (HRV)-40, HRV-75, HRV-78, and HRV-80. One of the four patients complained of anosmia, whereas another complained of dysosmia. Olfactory testing did not show significant improvement at 4, 8, 11, and 24 weeks after the first visit in the four patients, although results of acoustic rhinometry significantly improved. Two of the four patients complained of olfactory dysfunction even 6 months after the first visit. Coronavirus and parainfluenza virus were detected in one patient each, and Epstein-Barr viruses were detected in three patients. Conclusions This study for the first time detected rhinovirus, coronavirus, parainfluenza virus, and Epstein-Barr virus in nasal discharge of patients with PVOD. Furthermore, the present study suggests that rhinoviruses can cause olfactory dysfunction through mechanisms other than nasal obstruction and that rhinoviruses can induce various severities and different time courses of olfactory dysfunction.

Laminated polyester film

Abstract: The present invention provides a laminated polyester film which exhibits a good adhesion property to various adhesives, and can be suitably used in the applications in which a high total light transmittance is required, for example, as a member for protecting a polarizing plate of liquid crystal displays, in particularly, as a protective film disposed on a rear surface of a rear side polarizing plate. The laminated polyester film according to the present invention comprises a polyester film; a coating layer formed by applying a coating solution which comprises at least one resin selected from the group consisting of a polyester resin, an acrylic resin and a urethane resin, polyvinyl alcohol and an oxazoline compound, on one surface of the polyester film; and a coating layer formed on the other surface of the polyester film which has an absolute reflectance exhibiting one minimum value in a wavelength range of 300 to 800 nm wherein the minimum value is not more than 3.5%.
