Tinnitus emerging in the context of a COVID-19 infection seems not to differ in its characteristics from tinnitus unrelated to COVID-19.

Background and aim: COVID-19 is a respiratory disease caused by the new coronavirus SARS-CoV-2, for which the first cases were reported in China, by December 2019. The spectrum of clinical presentations is wide, ranging from asymptomatic cases to a severe acute respiratory syndrome, sometimes with multiple systems involvement. Viral infections, including those related to respiratory virus, may cause hearing loss and, by extent, considering its pathophysiology, tinnitus. A systematic review on inner ear related symptoms in patients with COVID-19 reported 4.5% occurrence rate of tinnitus, with high variance of prevalence between the studies. Our aim is to further explore the relationship between COVID-19 and tinnitus. For this purpose we analyzed a sample of people who had suffered from a COVID-19 infection in the city of Volta Redonda, Brazil. In detail, we compared those with new onset tinnitus during or after the COVID-19 infection with those without tinnitus and those with tinnitus onset before the COVID-19 infection. Methods: Fifty-seven patients over 18 years old and previously diagnosed with COVID-19 confirmed by a RT-PCR test were included. Patients were subdivided in three groups: no tinnitus (NT), tinnitus that already existed before COVID-19 (chronic tinnitus, CT) and tinnitus that arose during or after COVID-19 (post-COVID-19 tinnitus, PCT). Data concerning COVID-19 symptoms, drugs prescribed for COVID-19, tinnitus characteristics, comorbidities and other otological symptoms were collected. For all the patients, tonal audiometry and otoacoustic emissions were performed. Tinnitus patients fulfilled the Tinnitus Handicap Inventory (THI) and visual-analog scales (VAS) for loudness and distress. Patients with CT answered a simple question about the worsening of their tinnitus after COVID-19. Results: PCT was reported by 19.3% of the patients, while 22.8% reported CT. No statistical difference was found between CT and PCT concerning hearing function, tinnitus characteristics and tinnitus distress. There was also no statistically significant difference between PCT and NT with respect to COVID-19 symptoms and pharmacological COVID-19 treatment. Patients with CT reported worsening of their tinnitus after COVID-19. Conclusion: As with other viral infections, inner ear symptoms may be associated with COVID-19. In our sample patients with tinnitus onset before COVID-19 and those with tinnitus onset during or after COVID-19 did not differ significantly in their clinical characteristics and their hearing function, suggesting that tinnitus occurring in the context of a COVID-19 infection is not related to a unique pathophysiological mechanism. The comparison of COVID-19 patients, who developed tinnitus with those who did not develop tinnitus did not reveal any differences in COVID-19 symptoms or COVID-19 treatment. Thus, there was no hint, that a specific expression of COVID-19 is closely related to post COVID-19 tinnitus onset. Although some drugs used to treat tinnitus are known to damage the inner ear cells (especially hydroxychloroquine), we did not see any relationship between the intake of these drugs and tinnitus onset, eventually due to the short prescription time and low doses. Among those patients who had tinnitus before COVID-19 30,8% reported worsening after COVID-19. Overall, tinnitus emerging in the context of a COVID-19 infection seems not to differ from tinnitus unrelated to COVID-19. For further exploring the relationship of tinnitus and COVID-19, large population based studies are warranted.

Aspiracão de corpo estranho através de traqueotomia: descricão de um caso / Foreign body aspiration through tracheotomy: a case report

Paciente de 70 anos, sexo masculino, traqueotomizado há cerca de 7 anos devido a tumoracão laríngea. Durante o procedimento de limpeza da cânula aspirou, acidentalmente, um fragmento da escova de limpeza. Radiografia de tórax em PA evidenciou corpo estranho metálico em topografia de brônquio inferior direito. Realizada broncoscopia rígida sob anestesia geral, com passagem do tubo pelo espaco glótico, sem resistências, procedeu-se a remocão do corpo estranho, sem complicacões. O paciente evoluiu assintomático, sendo encaminhado ao servico de ORL em que fazia acompanhamento para reavaliacão do caso.

Tinnitus treatment with acamprosate: double-blind study.

UNLABELLED: Nowadays, the treatment of tinnitus is still a great challenge for the otolaryngologists. Many facts remain unknown in its pathophysiology, leading to many different therapies, with irregular results. Acamprosate is a drug used in alcoholism treatment, due to its regulating effects in glutamatergic and GABA neurotransmission, and has never been used before in the treatment of tinnitus AIM: To evaluate efficacy and safety of the acamprosate in the treatment of sensorineural tinnitus. STUDY DESIGN: Randomized clinical trial. MATERIAL AND METHOD: 50 patients with sensorineural tinnitus were divided into two groups: 25 received acamprosate and 25 placebo, for a period of 3 months, in a prospective double-blind study, being analyzed for its efficacy and safety by the subjective score from 1 to 10 given by the patient. RESULTS: We found a high index of success in the relief of tinnitus, about 86.9%. In 47.8% of the cases we found more than 50% relief. The incidence of side effects was low, 12%, all of them mild. CONCLUSION: Acamprosate, a drug used in the treatment of alcoholism, is a safe and successful alternative for sensorineural tinnitus' treatment.

Otite externa difusa aguda: um estudo prospectivo no verão do Rio de Janeiro / Acute diffuse external otitis: a prospective study in Rio de Janeiro's summer

A Otite Externa Aguda é uma doença extremamente comum em países tropicais, especialmente no verão. Vários fatores predisponentes são identificáveis e o quadro clínico pode ser bastante variado, principalmente com relação à intensidade da otalgia. OBJETIVO: Avaliar, através de um estudo prospectivo no maior hospital de Emergências do Rio de Janeiro, a incidência e as características da otite externa no período de verão. FORMA DE ESTUDO: Estudo clínico com coorte transversal. MATERIAL E MÉTODO: 391 pacientes com otite externa atendidos no Serviço de ORL do Hospital Souza Aguiar foram avaliados em uma série de parâmetros clínicos e de tratamento, incluindo análise de possíveis fatores predisponentes. RESULTADOS: Os principais sintomas referidos foram otalgia, otorréia discreta e plenitude auricular. Os principais fatores predisponentes foram banho de mar e piscina e uso de cotonetes. CONCLUSÃO: A otite externa aguda é uma doença extremamente comum em países tropicais, especialmente no verão. A possível contaminação da água de praias e piscinas, embora descartada por vários autores como fatores predisponentes, pode ter alguma influência na sua patogênese.

Corpos estranhos animados em otorrinolaringologia / Strange animated bodies in othorinolaringology

Forma de estudo: Clínico retrospectivo. Material e método: Foram reportados 56 casos de corpos estranhos animados em orelhas (55 insetos e 1 aracnídeo) e 1 caso (inseto) em fossas nasais. O material foi coletado no setor de Emergência do serviço de ORL do Hospital Municipal Souza Aguiar, no centro do Rio de Janeiro, entre os anos de 1998 e 2000, e identificado por zoólogos do Museu Nacional, Rio de Janeiro. A maior parte dos casos ocorreu em Nova Iguaçu e Campo Grande, sendo analisados os quadros clínicos e as complicaçöes ocorridas. Resultado: Os insetos säo: 30,35 por cento Blattaria (baratas); 25 por cento Diptera (moscas e mosquitos); 12,5 por cento Lepidoptera (borboletas e mariposas); 10,7 por cento Coleoptera (besouros); 7,15 por cento Hemiptera (percevejos, cigarras, afídeos, etc.), 5,35 por cento Hymenoptera (vespas, abelhas, formigas, marimbondos) e 5,31 por cento outros
