Background: Hearing impairment ranks third on the list of chronic health conditions of the elderly, after arthritis and hypertension. As average lifespans increase, it is likely that the proportion of people with hearing loss will also increase. The purpose of the study was to develop, standardize, and apply an Arabic version of the Hearing Handicap Inventory for the Elderly (HHIE). Results: The mean age of the 100 subjects included in the pretest was 64.92 ± 5.937 with age ranged from 60 to 84 years. The average score for each item (simple, clear, and relevant) for each separate question obtained more than 80% which is considered valid. One hundred percent of the participants reported that the entire inventory appeared simple, clear, and relevant, we further implied the jury opinion; the total score average of our jury for the entire inventory was calculated to determine the face validity of the questionnaire and found to be 89.81%. Responses of all participants for each question were collected and showed questions 8, 21, 6, 7, and 14 obtained the highest response results for both yes and sometimes. The HHIE showed high reliability (p value < 0.001) for all questions. The demographic data of the forty participants showed no statistically significant difference between the complaining group of hearing loss and the non-complaining group as regards age and gender. There was a highly statistically significant difference between the complaining group and the non-complaining group regarding the HHIE. The sensitivity of the HHIE was 79% for severe auditory handicapping and only 24% for mild-to-moderate auditory handicapping. Conclusion: The developed Arabic version of the HHIE has high reliability, validity, simplicity, and clarity which found consistent with the original English questionnaire and it performed well in the detection of hearing loss in elderly Egyptians. It can be applied in a large population and for use in surveys.
Objective: Vestibular-Evoked Myogenic potential (VEMP) is a non invasive test for vestibular function. It is a series of electrical waves that are generated by vestibular pathway in response to loud acoustic stimulation. It can be recorded from surface electrodes placed over muscles and according to the site of recording there are two types cervical VEMP and ocular VEMP. The primary goal of the present study is to compare cervical evoked myogenic potential (cVEMP) findings in normal hearing children and adults. Materials and Methods: This study included 60 subjects of normal hearing. They were selected from relatives; friends and relatives of patients attending Audiology Unit of Alzahraa University Hospital. 30 were children in the age range of 5-15 years and 30 were adults in the age range of 20-40 years. All subjects were submitted to cVEMP (air-conducted sound). Amplitude, latencies, asymmetry amplitude ratio and threshold were measured. Results: There was statistically significant difference in latencies and amplitudes and no statistically significant difference in asymmetry ratio of cVEMP responses between children and adults. There was no statistically significant difference in threshold between right and left ears in adult and children but there was statistically significant difference between the two groups as regard cVEMP threshold. Conclusion: cVEMPs responses in children have shorter latencies and lower thershold than adult responses, which should be considered in interpretation of cVEMP responses in children. Normative data for different age groups should be collected as cVEMPs responses, as age has a significant effect on them.
Background: Involvement of the brainstem in multiple sclerosis [MS] has significant implications on the disease course and can be presented with different symptoms. There are many tests able to detect brain-stem involvement in MS with various degrees of success. Aim of the work: To study the changes in vestibular evoked myogenic potential [VEMP], in patients with MS, and to detect its sensitivity for detection of the brain-stem lesions previously diagnosed with magnetic resonance imaging [MRI] in MS patients. Patients and Methods: Sixty participants had been enrolled and divided into two groups: 30 healthy subjects [Control group] and 30 MS patients [Study group]. Both groups had been subjected to otological examinations, pure tone audiometry, acoustic impedance, cervical vestibular evoked myogenic potential [cVEMP], ocular vestibular evoked myogenic potential [oVEMP] and MRI. Results: In MS group, oVEMP mean latencies of n1 and p1 and cVEMP mean p13 and n23 latencies were significantly prolonged. In addition, 14 MS patients [46.7%] had brainstem lesions as confirmed by MRI. Finally, oVEMP test had higher sensitivity than the cVEMP in prediction of brainstem lesions. Conclusion: oVEMP seems to be useful and more sensitive than cVEMP as an adjunct test in the evaluation of brain-stem dysfunction in MS patients.
