High Frequency Audiometry and Chronic Renal Failure

High frequency audiometry with pure tones from 9 to 18 kHz was performed in 37 patients with chronic renal failure undergoing conservative medical treatment and in a control group of 96 patients (age range 30-59 years for both groups). It was noted that the high frequency thresholds were significantly higher for the patients with chronic renal disease, and further deterioration of hearing function was observed at the examination performed after 1 year of follow-up. It was concluded that high frequency audiometry is a sensitive method for detecting hearing changes in patients with chronic renal failure and can be used to monitor these patients.High frequency audiometry with pure tones from 9 to 18 kHz was performed in 37 patients with chronic renal failure undergoing conservative medical treatment and in a control group of 96 patients (age range 30 59 years for both groups).

Reabilitação vestibular em idosos com tontura

BACKGROND: the aging of the population is a natural process and is manifested by a decline in the functions of several organs. Vestibular rehabilitation (VR) is a therapeutic process that seeks to promote a significant reduction in the symptoms of the labyrinth. AIM: to verify the benefits of VR exercises through the application of the Dizziness Handicap Inventory (DHI) questionnaire - Brazilian version - pre and post rehabilitation. METHOD: participants of this study were eight elderly patients with dizziness, ages between 63 and 82 years, three male and five female. The following procedures were carried out: medical history, otologic inspection, vestibular evaluation with vectoelectronystagmography (VENG), application of the DHI questionnaire and of the Cawthorne (1944) and Cooksey (1946) VR exercises. RESULTS: regarding the auditory and vestibular complaints which were referred to in the medical history, the following was observed: presence of tinnitus, hearing loss, postural vertigo and of unbalance. In the evaluation of the vestibular function alterations were observed for all of the participants, mainly in the caloric test, with a prevalence of unilateral and bilateral hypofunction. In the vestibular exam the following was observed: three cases of unilateral peripheral vestibular deficit syndrome, three cases of bilateral peripheral vestibular deficit syndrome, one case of bilateral central vestibular deficit syndrome and one case of irritating bilateral central vestibular syndrome. There was a statistically significant improvement of the following aspects after VR: physical (p=0.00413), functional (p=0.00006) and emotional (p=0.03268). CONCLUSION: the VR protocol favored the improvement of life quality of the participants and was of assistance in the process of vestibular compensation.

Características do zumbido em trabalhadores expostos a ruído

Tinnitus is a common auditory complaint among individuals exposed to noise. AIM: this paper aims to study the characteristics of tinnitus in workers exposed to noise. STUDY DESIGN: this is a descriptive prospective study. MATERIALS AND METHOD: Fifty-two individuals averaging 29 years of age were enrolled in a hearing loss prevention program at a meat processing plant. The participants were interviewed and had their hearing tested in 2005 and 2006. RESULTS: seventy-one percent of the participants were found to have normal hearing. Tinnitus was present in 16% of the males and in 9% of the females. Mean noise exposure length was 7 years and noise levels ranged from 86 to 91 dBA (48%). Bilateral tinnitus (46%) of the hissing type (40%) and moderate intensity (49%) was the most prevalent. Symptoms began to be observed within one to five years after initial exposure to noise (67%) and manifested themselves in weekly episodes (41%) that bothered the patients mostly at night (34%). A significant correlation was observed between the frequency of tinnitus episodes and the noise levels to which workers were exposed. CONCLUSION: tinnitus should be included in hearing loss prevention programs in order to more comprehensively promote occupational hearing health.

Reabilitação vestibular no tratamento da tontura e do zumbido

PURPOSE: To verify the effectiveness of vestibular rehabilitation exercises in the improvement of tinnitus and dizziness through an evaluation carried out before and after the administration of the Dizziness Handicap Inventory (DHI) and the Tinnitus Handicap Inventory (DHI) questionnaires, both adapted to the Brazilian population. METHODS: Six patients (two male and four female), with ages ranging from 43 to 70 years, were evaluated. The patients were submitted to the following procedures: anamnesis, otoscopy, vestibular evaluation through vectoelectronystagmography, and administration of the questionnaires, before and after vestibular rehabilitation, using the Cawthorne and Cooksey protocol. RESULTS: a) regarding the most related complaints, imbalance when walking (83,3%), headache (66,6%) and depression (66,6%), were observed; b) in the vestibular exam all the patients showed alterations in the caloric test, and the most frequent syndrome was the irritative peripheral vestibular (83,3%); c) two cases of irritative peripheral vestibular syndrome, two cases of irritative peripheral unilateral vestibular syndrome, one case of irritative peripheral bilateral vestibular syndrome and one case of peripheral deficient unilateral vestibular syndrome were verified in the vestibular exam; d) in the administration of the DHI, an improvement in the functional and emotional aspects were observed, with the physical aspect remaining unchanged; e) in the administration of the THI, an improvement was observed in all the aspects evaluated. CONCLUSION: The protocol of vestibular rehabilitation used in the study, promoted a decrease in tinnitus and dizziness, hence improving the quality of life of the patients.

Limiares auditivos em músicos militares: convencionais e altas frequências

PURPOSE: To analyze and characterize tonal auditory thresholds between 500 Hz and 16,000 Hz of professional musicians, specifically members of a military band. METHODS: A historic cohort study was carried out comparing one group of 50 professional musicians (military band) with another group (44 subjects) without history of professional exposure to intense sound; the groups were homogenous (p<0.05%) in relation to gender (male) and age (about 35 years old). Tone threshold audiometry for conventional (from 500 to 8,000 Hz) and high frequencies was applied (from 9,000 to 16,000 Hz). RESULTS: Exposure to music triggered permanent hearing impairment. As to conventional auditory thresholds, the exposed and non-exposed groups presented sensorineural hearing loss of 32 and 2.27%, respectively. The subjects exposed to music had 14.54 times more risks of acquiring sensorineural hearing loss than the non-exposed group. After 20 years of exposure to music, significant worsening was observed in auditory thresholds, especially at extended high frequencies, and differences occurred between the groups from the age of 30 on. CONCLUSION: Exposure to music caused permanent hearing impairment, showing differences in relation to the non-exposed group, registered in conventional audiometry and at high-frequency audiometry.

Vestibular rehabilitation: clinical benefits to patients with Parkinson's disease

OBJECTIVE To evaluate the effectiveness of the vestibular rehabilitation (VR) exercises by means of an assessment before and after the application of the Brazilian version of the Dizziness Handicap Inventory (DHI) questionnaire. METHOD Twelve patients were studied, the following procedures were carried out: anamnesis, otorhinolaryngological and vestibular evaluation, and the application of the DHI before and after the VR. RESULTS Clinically resting tremors and subjective postural instability were the motor complaints most frequently associated with complaints of vertigo in 12 cases (100%); in the vestibular exam, all the patients presented abnormalities, frequently from the uni and bilateral peripheral vestibular deficiency syndromes in 10 cases (83.3%); there was significant improvement in the physical, functional and emotional aspects of the DHI after the completion of the VR. CONCLUSION The VR following the Cawthorne and Cooksey protocol were shown to be useful in managing subjective complaints of several aspects evaluated in this protocol.
