Patient: Female, 67-year-old Final Diagnosis: SARS-CoV-2 Symptoms: Cough • fever • hearing Loss Medication: — Clinical Procedure: Intensive Care Unit (ICU) Specialty: Otolaryngology Objective: Unusual clinical course Background: Few reports have described the association between coronavirus disease 2019 (COVID-19) and sudden hearing loss. The precise pathophysiological mechanism causing this symptom is unknown. This report describes a case of sudden hearing loss in a patient with COVID-19 pneumonia due to SARS-CoV-2 infection. Case Report: A 67-year-old woman with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as confirmed by reverse transcription-polymerase chain reaction (RT-PCR) testing from nasopharyngeal and oropharyngeal swabs, was examined. She experienced sudden hearing loss in her right ear and disabling tinnitus. She underwent combined corticosteroid therapy (oral and intratympanic), resulting in an isolated improvement of 250 kHz in the right ear (from 60 dB, the threshold became 15 dB) and of 4, 6, and 8 kHz in the left ear (from 35 dB, 20 dB, and 35 dB, the thresholds became 15 dB, 5 dB and 20 dB, respectively). Conclusions: Although rare, hearing loss appears to be a possible sequela to SARS-CoV-2 infection and deserves attention because it is a medical emergency requiring immediate clinical treatment. Additional studies are needed to assess the pathophysiological mechanisms involved in and the long-term characteristics of this type of hearing loss.

Out of the many forms of therapy for sudden deafness, some require hospitalization and present significant risks. Aim: This prospective study analyzes etiology and evolution in cases of sudden deafness (SD) where outpatient oral treatment was used. Study design: clinical with transversal cohort. Material and Method: Forty cases of sudden hearing loss were followed for at least one year. All were submitted to initial clinical evaluation, auditory tests, routine blood analysis, and magnetic resonance imaging. All received initial treatment with pentoxifylline and prednisone. Results: 45% (n=18) presented normal auditory thresholds, 40% (n=16) showed some improvement in hearing, 15% (n=6) maintained initial hearing level. Nine cases (22.5%) presented clinical conditions possibly implicated in hearing loss (viral infection, immunomediated hearing loss, vascular disorders, and so on); three (7.5%) had cerebellopontine tumors. Evolution of hearing in these 12 cases with presumed etiology presented no differences from hearing in the 28 cases without any known etiological factor. Clinical treatment within the first seven days was the only statistically significantly different condition in patients who improved hearing. Conclusions: An objective search for etiological bases should be conducted in any case of acute sensorineural hearing loss. The presence of cerebellopontine tumors in 7.5% of cases of SD, among other treated causes, justifies a thorough clinical investigation in these patients. Overall good evolution of hearing was observed in 67.5% of cases of SD, regardless of its etiology. Therapy within the first seven days of SD was significantly related to better outcomes in hearing.

Bilateral submandibular gland excision with parotid duct ligation were safe to be performed in children, with 87% of success in drooling control.

Sudden deafness should be approached as a symptom common to different diseases. The presence of cerebellopontine angle tumors in 10.2% of our cases, among other treatable causes, justifies the recommendation of gadolinium-enhanced magnetic resonance use, not only to study the auditory peripheral pathway, but to study the whole auditory pathway including the brain.

Ai m: Verify the use of immunohistochemistry as a method to measure all forms of elastic fibers at human vocal folds. Study design: transversal cohort. Material and method: We collected vocal folds following these criterion: age between 25 and 40, Caucasian men, dead by gun shot, within 12 hours of death, without instrumentation of the larynx or suspicion of neck injury and without mucosal lesions noted by microscopy. Ten vocal folds were collected and one, of a man aged 28 years, was selected to study. The vocal fold was transversely cut in 9 regions and in each segment three slides were made. These slides were stained by Verhoeff and Weighert´s resorcin-fuchsin and used for immunohistochemistry. The elastic compound was measured by colorimetric software analysis. Results: In Verhoeff and Weighert´s resorcin-fuchsin, the intermediate and deep layer showed values higher than those of the superficial layer. The amount of tropoelastin identified by the antibody at the superficial layer was close to those of intermediate and deep layer. Conclusions: Immunohistochemistry is a method that can identify and measure all forms of elastic fibers at human vocal fold.

ObjectivesThe aim of the study was to assess whether hearing aids (HA) and cochlear implants (CI) bring benefits to cognition or mitigate cognitive decline in older adults.MethodsThis is a systematic literature review registered on the International Prospective Register of Systematic Reviews (PROSPERO) and based on the criteria recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The Population, Intervention, Comparison, Outcome, and Study type (PICOS) strategy was used to define eligibility. Studies that met the criteria were included in the qualitative synthesis. We assessed the risk of bias through the Joanna Briggs Institute Critical Appraisal Checklists.ResultsA total of 3,239 articles, found in eight databases, addressed the relationship between HA, CI, and cognition. We selected 30 experimental articles reporting measures of cognitive outcomes for older adults to include in the qualitative analysis. Of those, 23 studies reported a significant improvement in outcome and seven reported no significant change.ConclusionsThis systematic review indicates that CI and HA can bring benefits to cognition in older adults.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021273690
