Background: Objective data on chemosensitive disorders during COVID-19 are lacking in the Literature.Methods: Multicenter cohort study that involved four Italian hospitals. Three hundred and forty-five COVID-19 patients underwent objective chemosensitive evaluation.Results: Chemosensitive disorders self-reported by 256 patients (74.2%) but the 30.1% of the 89 patients who did not report dysfunctions proved objectively

BACKGROUND: since the beginning of COVID-19 outbreak a growing number of symptoms and deficits associated with the new pathology have emerged, among them cochlear damage in otherwise asymptomatic COVID-19 patients has been described. OBJECTIVE: to investigate general and audiovestibular symptoms and sequelae in healed patients, and to seek for any sign of residual or permanent hearing or vestibular loss. METHODS: we reviewed the data coming from 48 Covid-19 patients whose nasopharyngeal swabs have turned negative, all employed at our facility, that opted in for a free screening of audiovestibular symptoms offered by our hospital after the aforementioned report was published. The screening included a tonal pure tone audiometry, a vHIT and SHIMP test, as well as a survey including known symptoms and audiovestibular symptoms. RESULTS: general symptoms as reported by our patients largely reflect what reported by others in the literature. 4 (8.3%) patients reported hearing loss, 2 (4.2%) tinnitus, 4 dizziness (8.3%), 1 spinning vertigo (2%), 1 dynamic imbalance (2%), 3 static imbalance (6.3%). Most audiovestibular symptoms have regressed. Thresholds at pure tone audiometry and vHIT gain were within normality range in all post-Covid-19 patients. CONCLUSIONS: even if some patients suffer from audiovestibular symptoms, these are mostly transitory and there is no clear evidence of clinically relevant persistent cochlear or vestibular damage after recovery.

Design: Monocentric retrospective study whose target population included all the newborns born in or referred to our hospital in 2019 and 2020.Results: There is no statistically significant difference in time to retest or loss to follow-up rate between the 2 years considered (2019 to 2020). Referral rate is not higher for newborns born to severe acute respiratory syndrome coronavirus 2 polymerase chain reaction positive mothers. Conclusions:In relation to the analyzed variables, coronavirus disease 2019 seems to have a limited impact on our screening program. Severe acute respiratory syndrome coronavirus 2 did not behave as an audiological risk factor in our series.
