Introduction

Measuring the impact on quality of life, especially after the beginning of the treatment, is becoming increasingly important in healthcare.

Objective

The aim of this study was to translate the Chronic Otitis Media Questionnaire-12 (COMQ-12) into Portuguese language and validate this version in a group of patients with chronic otitis media.

Methods

The Portuguese version of COMQ-12 was obtained by translation and back translation. Portuguese speaking patients with a history of active chronic otitis media were asked to complete the COMQ-12 Portuguese version. Cronbach's α coefficient was calculated for an estimation of the internal consistency of the questionnaire.

Results

A total of 100 patients were included in the study; 49 women and 51 men, with a mean age of 39 years (range 12–77 years, median 40 years). The average COMQ-12 score was 29, out of a maximum score of 60. Cronbach's α result for the Portuguese version of the COMQ-12 was 0.85, indicating a high internal consistency. The participants presented with different forms of chronic otitis media, and almost all domains of the COMQ-12 questionnaire were able to differentiate between patients with healed chronic otitis media and patients with cholesteatoma or wet tympanic membrane perforation. Showing that patients with healed chronic otitis media have a better quality of life, measured by the COMQ-12, is a first step to guarantee the questionnaire's validity. The next step will consist on routinely using the questionnaire in patients undergoing surgery for chronic otitis media in order to evaluate their quality of life after treatment.

Conclusion

The COMQ-12 Portuguese version showed high reliability, and may be used as an assessment of quality of life in patients with chronic otitis media.  相似文献

IntroductionOtological symptoms contribute to the disability of established Parkinson's disease (PD). We sought to evaluate whether prodromal onset may affect PD progression.MethodsA retrospective cohort design was used to compare time to advanced disease, defined as a Hoehn & Yahr stage ≥3 in consecutive PD patients with history of auditory and/or vestibular symptoms appearing before versus after PD onset. Time from PD onset to H&Y ≥ 3 was determined using Cox proportional hazards, with adjusted results summarized as hazards ratio (HR).ResultsAfter adjusting for age at PD onset, there was a lower risk of progression to advanced disease in patients with prodromal otological symptoms compared to those with otological symptoms after PD onset (HR = 0.34; 95%CI: 0.15–0.75, p = 0.008). This association remained significant after adjusting for age at PD onset and MDS-UPDRS III (HR = 0.25; 95% CI: 0.10–0.63, p = 0.003) and propensity score-adjusted analysis (HR = 0.46; 95% CI: 0.24–0.91, p = 0.025).ConclusionProdromal otological symptoms might be associated with a reduced risk of motor progression in PD.  相似文献

Objectives

To determine whether systemic administration of voriconazole and caspofungin causes ototoxicity.

Methods

This study was conducted on 32 healthy male Wistar albino rats. The baseline auditory brainstem response (ABR) thresholds of all animals were obtained under general anesthesia. Then, the rats were randomly divided into 4 groups (groups I-IV), each group consisting of 8 rats. Rats in group I were injected intraperitoneally with voriconazole 10 mg/kg/day for 7 days, and the rats in the group II were injected intraperitoneally with caspofungin 5 mg/kg/day for 7 days. Group III received 120 mg/kg/day gentamicin for 7 days. Group IV received saline for 7 days. The animals were then observed for 7 days, and on 14th day of the trial, posttreatment ABRs of both ears were recorded.

Results

We did not find any significant differences between pretreatment and posttreatment median ABR thresholds in the voriconazole, caspofungin, or saline groups. In the gentamicin group, there was a statistically significant difference between pretreatment and posttreatment ABR thresholds.

Conclusion

Caspofungin and voriconazole did not change ABR thresholds in speech frequencies after a 7-day-period of their administration. We believe that further animal studies must be performed after administration of these agents for a longer time period, and these findings must be consolidated with histopathological investigations.  相似文献
