Background The COVID-19 pandemic has made wearing face masks a common habit in public places. Several reports have underlined the increased difficulties encountered by deaf people in speech comprehension, resulting in a higher risk of social isolation and psychological distress. Purpose To address the detrimental effect of different types of face masks on speech perception, according to the listener hearing level and background noise. Research Design Quasi-experimental cross-sectional study. Study Sample Thirty patients were assessed: 16 with normal hearing [NH], and 14 hearing-impaired [HI] with moderate hearing loss. Data Collection and Analysis A speech perception test (TAUV) was administered by an operator trained to speak at 65 dB, without a face mask, with a surgical mask, and with a KN95/FFP2 face mask, in a quiet and in a noisy environment (cocktail party noise, 55 dB). The Hearing Handicap Index for Adults (HHI-A) was administered twice, asking subjects to complete it for the period before and after the pandemic outburst. A 2-way repeated-measure analysis of variance was performed. Results The NH group showed a significant difference between the no-mask and the KN95/FFP2-mask condition in noise (p = 0.01). The HI group showed significant differences for surgical or KN95/FFP2 mask compared with no-mask, and for KN95/FFP2 compared with surgical mask, in quiet and in noise (p Conclusion Face masks have a detrimental effect on speech perception especially for HI patients, potentially worsening their hearing-related quality of life.

Interactions between SARS-CoV-2 and pharyngeal associated lymphoid tissue are thought to influence the manifestations of COVID-19. We aimed to determine whether a previous history of tonsillectomy, as a surrogate indicator of a dysfunctional pharyngeal associated lymphoid tissue, could predict the presentation and course of COVID-19.Multicentric cross-sectional observational study involving seven hospitals in Northern and Central Italy. Data on the clinical course and signs and symptoms of the infection were collected from 779 adults who tested positive for SARS-CoV-2, and analysed in relation to previous tonsillectomy, together with demographic and anamnestic data.Patients with previous tonsillectomy showed a greater risk of fever, temperature higher than 39°C, chills and malaise. No significant differences in hospital admissions were found.A previous history of tonsillectomy, as a surrogate indicator of immunological dysfunction of the pharyngeal associated lymphoid tissue, could predict a more intense systemic manifestation of COVID-19. These results could provide a simple clinical marker to discriminate suspected carriers and to delineate more precise prognostic models.COVID-19 nella popolazione tonsillectomizzata.Si ritiene che le manifestazioni dell’infezione da SARS-CoV-2 siano influenzate dalle interazioni tra il virus e il tessuto linfatico associato alla faringe. Obiettivo di questo studio è determinare se una pregressa tonsillectomia, come indicatore surrogato di disfunzione immunologica faringea, possa predire la presentazione e il decorso della COVID-19.Studio multicentrico trasversale osservazionale coinvolgente 7 centri italiani. Sono stati raccolti i dati su decorso, segni e sintomi dell’infezione da 779 adulti positivi al SARS-CoV-2, e analizzati in relazione a pregressa tonsillectomia, dati demografici e anamnestici.I pazienti con pregressa tonsillectomia hanno un maggior rischio di sviluppare febbre, raggiungere temperature oltre i 39°C, brividi e malessere generalizzato. Non si riscontrano differenze nel tasso di ospedalizzazione.Il dato anamnestico di pregressa tonsillectomia, come indicatore di disfunzione immunologica faringea, può predire una manifestazione sistemica più intensa nei pazienti affetti da COVID-19. Questi risultati possono fornire un marker clinico semplice per discriminare sospetti portatori del virus e delineare modelli prognostici più accurati.
