Objective The current study showed the relation between otitis externa and COVID-19 infection and compared otitis externa with other symptoms of COVID-19 as anosmia. Methods 257 cases who were confirmed positive for COVID-19, were examined otoscopic and endoscopic for otitis externa, onset of starting symptoms of otitis externa and its relation to days of infection with COVID-19 were documented and the prevalence of otitis externa with anosmia in the study group were estimated. Results Increased incidence of otitis externa in COVID-19 patients (18% of study group) and symptoms starting mainly between the 5th to 8th day of COVID-19 infection. Combined otitis externa and anosmia occurred in 13% of study group. Conclusions Otitis externa has a relation to COVID-19 infection. Further research needed to study its pathogenesis and mechanisms.
Glaucoma is a chronic, degenerative optic neuropathy, which cause progressive damage to the optic nerve, retinal ganglion cell (RGC) death and characteristic damage to the visual field. Current glaucoma therapeutics lower intraocular pressure (IOP) but they do not repair the damaged optic nerve or reverse vision loss. So, new treatment strategies are in demand. Stem cell therapy presents a new intervention that holds great promise for reversing vision loss. There are at least 3 potential targets for stem cell therapy in glaucoma: the retinal ganglion cells , the optic nerve head, and the trabecular meshwork. Stem cells also have a neuroprotective effect in glaucoma by improving retinal ganglion cell survival. There are many obstacles in using stem cells in glaucoma as the regulation of differentiation, integration, host immune response, tumorigenesis and ethical concerns.
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.
