Cystic fibrosis (CF) is considered one of the most prevalent lethal genetic disorders. The life expectancy of those patients has been rising. Besides the well-known prevalence of chronic ...rhinosinusitis, neurosensory hearing loss (NSHL) due to the large use of ototoxic antibiotics may be another problem that should receive special attention in otolaryngology (ENT).
Define retrospectively the prevalence of NSHL among patients with CF from the Hospital de Clínicas de Porto Alegre (HCPA) and based on this data discuss the need for a specific out patient ENT-CF clinic.
Files from CF HCPA patients were reviewed for age at diagnosis, the current age, types of antibiotics used, number of treatments, percentage with audiologic evaluation and its respective results.
One hundred and seven files were reviewed. The mean age at diagnosis was 1.33 years old (SD 1.97, range 0-12). The mean age of the sample was 7.87 (SD 4.49, range 1-22). Audiologic evaluation was performed in 39.3% (42) of the patients. 28.56% (12) had some degree of NSHL, while 36.3% did not present acoustic reflex. From 667 treatments with antibiotics, 49.5% were with tobramycin, 43.4% with amycacin and 7% with gentamicin.
The prevalence of NSHL among CF patients supports the need for a specific ENT-CF outpatient clinic. This clinic would help on the prevention and treatment of NSHL due to the use of ototoxic antibiotics and on the better understanding/control of rhinosinusal disorders.
Stapes surgery is one of the approaches indicated to treat conductive hearing loss secondary to otosclerosis. The procedures requires skill and experience from the surgeon and is part of medical ...residency training. Aims: To assess which type of prosthesis (Teflon or metal/steel) presents the best results in surgeries performed by residents and the incidence of complications. Materials and methods: we retrospectively assessed 189 interventions that counted on the active participation of resident physicians, and we compared the two types of prosthesis used. Audiometric results were analyzed following the guidelines from the Committee on Hearing and Equilibrium and also according to the Amsterdam Hearing Evaluation Plots. Results: Bone-air gap reduced in an average value of 21.90 dB (p<0.05) after the surgery in the group that received the Teflon prosthesis and 21.37 dB (p<0.05) in the group that received the mixed prosthesis, and gain in SRI was of 22.33 and 26.10 dB (p<0.05), and the air-bone gap was below 20 dB in 80.6% and 85.04%, respectively. Conclusions: We did not see differences in the audiometry and in the incidence of complications when we compared the type of prosthesis used. We believe it is valid to continue teaching this procedure in medical residency training programs, regardless of the type of prosthesis.
Fundamentação: A fibrose cística (FC) é uma das doenças genéticas letais mais comuns. Nos últimos anos, a sobrevida dos pacientes portadores dessa doença tem aumentado em decorrência principalmente ...do uso de antibióticos profiláticos e terapêuticos. Estes apresentam potencial ototóxico, sendo responsáveis por perdas auditivas sensorioneurais (SSN). Além disso, os pacientes com FC apresentam rinossinusopatias, sintomáticas e assintomáticas, que também necessitam de acompanhamento adequado. Objetivos: Definir a prevalência de alterações auditivas sensorioneurais (SSN) e rinossinusopatias nos pacientes com FC do Hospital de Clínicas de Porto Alegre (HCPA); descrever os possíveis fatores relacionados com tais incidências; e, a partir dessas informações, projetar o funcionamento do ambulatório de otorrinolaringologia (ORL) e FC do HCPA. Material e Métodos: Estudo retrospectivo, em que foram revisados os prontuários de pacientes com FC do Ambulatório de Pneumologia Infantil e de Adultos do HCPA. Foi criado um protocolo a ser preenchido em que se buscava a descrição do perfil da amostra em relação à idade do diagnóstico da doença, idade atual, tipos de antibióticos já utilizados, média do número de tratamentos, percentual que possui avaliação auditiva com resultados, e, por último, investigação radiológica e resultados. Resultados: Foram revisados 107 prontuários de pacientes com FC. A idade média da amostra foi de 7,87 anos e 1,33 anos a idade média de diagnóstico de FC. Os exames audiométricos foram realizados por 39,3% (42) das crianças, encontrando-se 28,56% (12) casos de SSN de graus variados. Um percentual mais elevado apresentava ausência de reflexo estapédico (36,3%). Somente 24,3% (26) realizaram RX dos seios da face nos quais 96.9% estavam alterados. Um total de 667 tratamentos com aminoglicosídeos, sendo 49.5% com tobramicina, 43.4% com amicacina e 7% com gentamicina. Conclusão: Diante desses resultados mostra-se necessário um ambulatório específico de otorrinolaringologia e de FC para acompanhamento desses pacientes. O Ambulatório terá como objetivo auxiliar na prevenção e tratamento das perdas auditivas decorrentes dos tratamentos com aminoglicosídeos, assim como tratar, quando necessário, das vias aéreas superiores em relação à obstrução e inflamação associadas a presença de pólipos rinossinusais. Este ambulatório já está em funcionamento.

Tinnitus can greatly impact an individual’s life quality and it is very difficult quantify. Aim: To determine the reproducibility and validity of a Brazilian Portuguese version of the Tinnitus ...Handicap Inventory (THI), a self-applicable questionnaire which assesses tinnitus impact on patients’ life quality. Materials and Methods: This was a prospective transversal study. The questionnaire was translated into Portuguese and cross-culturally adapted to the Brazilian environment according to internationally recommended methods. The Portuguese version of the THI was answered by 180 patients who complained of tinnitus. Reproducibility was assessed using the Cronbach’s Alpha Calculation; and the validity was assessed by means of the Beck Depression Inventory (BDI), calculating the Pearson correlation coefficient. Results: The Portuguese version of the THI showed high internal validity, comparable to the original version. A high correlation was observed between the THI and the BDI. Conclusion: The Brazilian Portuguese version of THI is a valid and reproducible tool used to quantify how tinnitus impact the life quality of those Brazilian patients who complain of this symptom.
OBJETIVO: A doxorrubicina, um dos fármacos mais utilizados no tratamento do câncer, apresenta toxicidade cardiopulmonar acentuada, muitas vezes impedindo o tratamento completo. O tocoferol (vitamina ...E), por sua vez, demonstrou atenuar os efeitos cardiotóxicos provocados pela doxorrubicina, permitindo o uso de uma dose maior. Em trabalho anterior, desenvolvemos um modelo constante de injúria pulmonar induzida pela doxorrubicina em pulmões de ratos (dose de 7 mg/kg). O objetivo deste estudo é testar o possível efeito protetor do tocoferol no modelo desenvolvido. MÉTODO: Utilizou-se 24 ratos Wistar, machos, pesando entre 250-350g. O grupo 1 recebeu soro intragástrico (IG) e soro intravenoso (IV); o grupo 2 recebeu tocoferol IG (400 UI) e soro IV; o grupo 3 recebeu soro IG e doxorrubicina IV e o grupo 4 recebeu tocoferol IG e doxorrubicina IV. Após sacrifício, o bloco pulmonar de cada rato foi analisado histologicamente. RESULTADOS: Os achados microscópicos foram pré-estabelecidos (congestão, hemorragia e necrose). O grupo 1 (controle) não apresentou alterações importantes. O grupo 3 (doxorrubicina) apresentou dano estabelecido previamente. O grupo 4 (doxorrubicina e tocoferol) e o grupo 2 (tocoferol) apresentaram dano importante, mas sem diferença estatística (p>0,05). CONCLUSÕES: O tocoferol poderia ter efeito na diminuição do dano intersticial, uma vez que tem sido utilizado na proteção cardíaca. Entretanto, não houve diferença em relação aos danos previamente estabelecidos.
BACKGROUND: To test the possible protective effect of tocopherol in a developed model of lung injury induced by doxorubicin in rats. METHODS: Twenty-four males Wistar rats weighing between 250-350g were submitted to one of the four treatment groups. Group 1 received intragastric serum (IG) and endovenous serum (EV); group 2 received tocopherol IG (400 UI) and serum EV; group 3 received serum IG and doxorubicin EV and group 4 received tocopherol IG and doxorubicin EV. After death, the pulmonary unit of each rat was histologically analyzed. RESULTS: The microscopical findings had been previously established (congestion, hemorrhage and necrosis). Group 1 (control) did not present any important finding. Group 3 (doxorubicin) presented damages, which were previously established. Group 4 (doxorubicin and tocopherol) and group 2 (tocopherol) had presented important damage, but they did not differ statistically (p0.05). CONCLUSION: Tocopherol could have some effect in the reduction of the interstitial damage, once it has been used for cardiac protection. However, we did not find differences in damages previously established. The preliminary findings had not evidenced to be the Vitamin E, a protective substance of pulmonary damages produced by the doxorubicin in rats, in the managed dose. However, a larger number of rats may be required for scientific evidence of this hypothesis.

A cirurgia do estapédio é um dos tratamentos indicados para a melhora da surdez condutiva secundária à otospongiose. O procedimento requer habilidade e experiência do cirurgião e faz parte do ...treinamento durante a residência médica. OBJETIVOS: Avaliar qual tipo de prótese (teflon ou mista de metal e aço) apresenta melhores os resultados auditivos em cirurgias realizadas por residentes e a incidência de complicações. MATERIAL E MÉTODOS: Foram avaliadas retrospectivamente 189 intervenções cirúrgicas que tiveram participação ativa de residentes, comparando-se os dois tipos de prótese utilizados. Os resultados audiométricos foram analisados conforme orientação do Committee on Hearing and Equilibrium e segundo o Amsterdam Hearing Evaluation Plots. RESULTADOS: O gap aéreo-ósseo diminuiu em média 21,90 dB (p<0,05) após o procedimento cirúrgico no grupo da prótese de teflon e 21,37 dB (p<0,05) no grupo da prótese mista, sendo o ganho do IRF de 22,33 e 26,10 dB (p<0,05), e o gap aéreo-ósseo foi inferior a 20 dB em 80,6% e 85,04%, respectivamente. CONCLUSÕES: Não evidenciamos diferenças no resultado audiométrico e na incidência de complicações quando comparamos o tipo de prótese utilizada. Acreditamos ser válida a execução desse procedimento em serviços de treinamento de médicos residentes, independente do tipo de prótese.
