There is no routinely determined treatment for olfactory dysfunction because of COVID-19. Saline irrigation and nasal corticosteroid treatments are safe and inexpensive methods, and have low side effects. In our study, we argue that saline nasal irrigation and topical corticosteroid treatment can be used in the treatment of patients with olfactory loss in all areas of rhinology. A total of 150 patients who admitted to our clinic with other symptoms or with only acute odor loss, diagnosed with COVID-19 with RT-PCR were divided into 3 equal groups.Fifty patients in Group 1 were not given any extra treatments. The other 50 patients in Group 2 were given saline irrigation for treatment; and the 50 people in Group 3 were given both saline irrigation and nasal steroid spray for treatment. The ''Subjective Olfactory Capability (SOC)'' was used for olfactory function evaluation of patients. Self-Rating Olfactory Score (SROS), and Olfactory Dysfunction Duration (ODD) were recorded on the 1st, 15th and 30th days. SROS of the group receiving Nasal Saline ? Triamcinolone Acetonide treatment on the 30th day was significantly higher than in other groups (p 21-3 = 0.018, p 223 = 0.033). Also, the ODD was significantly reduced in this group compared to other groups (p 21-3 = 0.022, p 223 = 0.028,). Topical triamcinolone treatment was found to be successful in the treatment of olfactory dysfunction due to COVID-19. Nasal steroids, which are both inexpensive and have low side effect profiles, can be used safely in the treatment of patients with olfactory losses.
Objective: Triclosan is utilized as an antibacterial factor in many industrial products. Although there are many toxic features of triclosan in the literature, there is no study on the effect of triclosan on hearing. The purpose of this study is to determine the effect of triclosan on hearing in rats.
Methods: In this prospective, experimental animal study, 40 healthy Sprague-Dawley rats with normal response to the distortion-product otoacoustic emission (DPOAE) measurements were divided into four groups. Group 1, as the control group, was given only corn oil, group 2 was given 5 mg/kg triclosan dissolved in corn oil, group 3 was given 10 mg/kg triclosan dissolved in corn oil, and group 4 was given 100 mg/kg triclosan dissolved in corn oil; triclosan and corn oil were administered by oral gavage to all groups.
Results: In our study, low-dose triclosan did not cause hearing loss, but hearing loss was observed in the group that was given high-dose triclosan (100 mg/kg).
Conclusion: These findings suggest that triclosan causes hearing loss in rats. This issue should be investigated further to avoid triclosan ototoxicity in humans.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
