    Int J Audiol, 2019 02;58(2):63-76.
    PMID: 30646766 DOI: 10.1080/14992027.2018.1531154
    OBJECTIVE: To conduct a systematic review of the evidence in relation to what hearing healthcare professionals do during hearing aid consultations and identifying which behaviours promote hearing aid use and benefit among adult patients.

    DESIGN: Searches were performed in electronic databases MEDLINE, EMBASE, CINAHL, PsycInfo, Web of Science, PubMed and Google Scholar. The Crowe Critical Appraisal Tool and Melnyk Levels of Evidence were used to assess quality and level of evidence of eligible studies. Behaviours of hearing healthcare professionals were summarised descriptively.

    STUDY SAMPLE: 17 studies met the inclusion criteria.

    RESULTS: Twelve studies described behaviours of audiologists and five studies were intervention studies. Audiologists were typically task- or technically-oriented and/or dominated the interaction during hearing aid consultations. Two intervention studies suggested that use of motivational interviewing techniques by audiologists may increase hearing aid use in patients.

    CONCLUSIONS: Most studies of clinicians' behaviours were descriptive, with very little research linking clinician behaviour to patient outcomes. The present review sets the research agenda for better-controlled intervention studies to identify which clinician behaviours better promote patient hearing aid outcomes and develop an evidence base for best clinical practice.

  2. Fulltext Visual analog scale in hearing loss
    Bokari S, Prepageran N, Raman R
    Indian J Otolaryngol Head Neck Surg, 2010 Jan;62(1):40-3.
    PMID: 23120679 DOI: 10.1007/s12070-010-0004-x
    OBJECTIVE: To determine if visual analog scale (VAS) that has been used to measure magnitude of internal states such as pain, mood and various functional capabilities can be applied for patients with hearing loss.

    MATERIALS AND METHODS: One hundred and sixty patients, aged 12-80 years with unilateral hearing loss were studied using a VAS (1-10) and pure tone audiometry (PTA) of responses to 500, 1,000 and 2,000 Hz to determine degree and type of hearing loss. The results of both were compared to determine if VAS can be used in measuring hearing loss.

    RESULTS: Patients with mild, moderate hearing loss correlate well with corresponding VAS but other degrees of hearing loss (severe and profound) have poor correlation. The best correlation between PTA and VAS were found in conductive type of hearing loss.

    CONCLUSION: This study suggest that there may be a role for VAS in mild and moderate hearing loss. This may be more applicable in rural setting as a screening procedure when audiometry is not available and can enhance clinical hearing assessment especially in mild-to-moderate conductive hearing loss.

    PMID: 23770961 MyJurnal
    The Vibrant Soundbridge is a new middle ear implantable hearing device. It was first introduced for adult patients with moderate to severe sensorineural hearing loss. With the innovation of the surgical techniques, its usage had been broadened for children and those patients with conductive and mixed hearing loss. We report first two cases of monoaural Vibrant Soundbridge implantation in Malaysia. They were children with bilateral conductive hearing loss who had failed to benefit from previous hearing aids. Floating mass transducers were attached in oval window and long process of incus respectively. Remarkable hearing yield was observed without surgical complication.

  4. Vestibular nerve section in a child with intractable Menière's disease
    See GB, Mahmud MR, Zurin AA, Putra SH, Saim LB
    Int J Pediatr Otorhinolaryngol, 2002 May 31;64(1):61-4.
    PMID: 12020915
    Clinical presentation of Menière's disease in children is not as typical as in adults. The triad of vertigo, tinnitus and deafness are not usually elicited, diagnosis often being made after years of follow up and batteries of investigation. A case of Menière's disease in a 3-year-old boy is presented. The diagnosis was only obvious at the age of 8 when the triad of vertigo, deafness and tinnitus were present. His disease progressed despite a trial of intratympanic gentamicin injections and endolymphatic sac decompression. Vestibular nerve section was subsequently performed for his intractable disease. Following the procedure he was asymptomatic and able to attend school.

    PMID: 26417253
    Tinnitus is a common disorder, it can be classified as pulsatile and non-pulsatile or objective and subjective. Pulsatile tinnitus is less common than non-pulsatile and can be due to vascular tumour such as glomus or vascular abnormality. We presented an interesting case of a 30 year-old Malay lady with a two-year history of pulsatile tinnitus which was worsening in three months duration. It was associated with intermittent headache. Clinical examination and tuning fork test were unremarkable. Apart from mild hearing loss at high frequency on the left ear, the pure tone audiogram (PTA) was otherwise normal. In view of the patient's young age with no risk factor for high frequency loss, a magnetic resonance imaging (MRI) was performed to look for any abnormality in the cerebellopontine angle. It revealed a single vessel looping around the left vestibulocochlear and facial nerves at the cisternal portion, likely a branch of the anteroinferior cerebellar artery (AICA). Literature review on the pathophysiology and treatment option in this condition is discussed.

  6. Vancomycin administration in continuous ambulatory peritoneal dialysis: the risk of ototoxicity
    Gendeh BS, Gibb AG, Aziz NS, Kong N, Zahir ZM
    Otolaryngol Head Neck Surg, 1998 Apr;118(4):551-8.
    PMID: 9560111
    A prospective study was undertaken in 16 patients with chronic renal failure on continuous ambulatory peritoneal dialysis, with 22 episodes of peritonitis treated with vancomycin, a known ototoxic agent. Twelve patients had one episode each, and four had recurrent peritonitis. Each treatment course consisted of two infusions of vancomycin (30 mg/kg body weight) in 2 L of peritoneal dialysate administered at 6-day intervals. Serum vancomycin analyzed by enzyme immunoassay showed a mean trough level of 11.00 microg/ml on day 6 and mean serum levels of 33.8 and 38.6 microg/ml about 12 hours after administration on days 1 and 7, respectively. Similar levels, well within the therapeutic range, were encountered with repeated vancomycin therapy for recurrent episodes of peritonitis, suggesting that no changes occurred in the pharmacokinetic profile of the drug. Pure-tone audiometry, electronystagmography, and clinical assessment performed during each course of treatment showed no evidence of ototoxicity even on repeated courses of vancomycin therapy. The results suggest that vancomycin therapy when given in appropriate concentrations as a single therapeutic agent is both effective and safe. We believe, however, that vancomycin administered in combination with an aminoglycoside may produce ototoxic effects that may be greatly aggravated, possibly because of synergism.

    Epileptic Disord, 2014 Sep;16(3):375-9.
    PMID: 25167568 DOI: 10.1684/epd.2014.0671
    Hearing loss has been reported with valproic acid (VPA) use. However, this is the first case of VPA-induced hearing loss that was tested and confirmed with a VPA rechallenge, supported by serial audiometry and pharmacokinetic modelling. A 39-year-old truck driver with temporal lobe epilepsy was treated with VPA at 400 mg, twice daily, and developed hearing loss after each dose, but recovered within three hours. Hearing loss fully resolved after VPA discontinuation. Audiometry performed five hours after VPA rechallenge showed significant improvement in hearing thresholds. Pharmacokinetic modelling during the VPA rechallenge showed that hearing loss occurred at a level below the therapeutic range. Brainstem auditory evoked potential at three months after VPA discontinuation showed bilateral conduction defect between the cochlear and superior olivary nucleus, supporting a pre-existing auditory deficit. VPA may cause temporary hearing threshold shift. Pre-existing auditory defect may be a risk factor for VPA-induced hearing loss. Caution should be taken while prescribing VPA to patients with pre-existing auditory deficit.

    Introduction: Exposure to excessive noise is the major avoidable cause of permanent hearing impairment. Sawmill is one of the workplaces where workers are exposed to hazardous noise level. This study was conducted to determine the reliability and validity of noise-induced hearing loss questionnaire among sawmill workers. Materials and Methods: This cross sectional study was conducted in March 2007 among 35 consented sawmill workers. A total of 40 items; 10 items for knowledge (8 areas), 20 items for attitude (7 areas) and 10 items for practice (2 areas) were assessed. Statistical analysis for reliability analysis was test by internal consistency and construct validity by exploratory factor analysis using principal components and Varimax rotation method. Results: Cronbach’s alpha coeffi cients were acceptable for attitude (0.90) and practice
    (0.75). However, it was low for knowledge (0.67). Exploratory factor analysis showed three meaningful exploratory factors that could explain the three dimensions in the questionnaire. Conclusion: The results of the validation study suggested that the noise-induced hearing loss questionnaire is reliable and valid tool for assessing knowledge, attitude and practice among sawmill workers.

    Patient’s self-perceived handicap inventory is an important tool for modern’s health care management including hearing loss. The HHIA is a selfreporting outcome measurement invented to identify hearing-impaired patients’ complaints for appropriate client-centred rehabilitation program. HHIA has been
    reported among one of the valid self-perceived hearing handicap measures, and could even addressed issues for patient with mild and unilateral hearing loss. This study aims to translate HHIA into Malay language (HHIA-M) and to adapt the questionnaire culturally for clinical use among Malaysian population.

  12. The spatial percept of tinnitus is associated with hearing asymmetry: Subgroup comparisons
    Genitsaridi E, Kypraios T, Edvall NK, Trpchevska N, Canlon B, Hoare DJ, et al.
    Prog Brain Res, 2021;263:59-80.
    PMID: 34243891 DOI: 10.1016/bs.pbr.2021.04.006
    The spatial percept of tinnitus is hypothesized as an important variable for tinnitus subtyping. Hearing asymmetry often associates with tinnitus laterality, but not always. One of the methodological limitations for cross-study comparisons is how the variables for hearing asymmetry and tinnitus spatial perception are defined. In this study, data from two independent datasets were combined (n=833 adults, age ranging from 20 to 91 years, 404 males, 429 females) to investigate characteristics of subgroups with different tinnitus spatial perception focusing on hearing asymmetry. Three principle findings emerged. First, a hearing asymmetry variable emphasizing the maximum interaural difference most strongly discriminated unilateral from bilateral tinnitus. Merging lateralized bilateral tinnitus (perceived in both ears but worse in one side) with unilateral tinnitus weakened this relationship. Second, there was an association between unilateral tinnitus and ipsilateral asymmetric hearing. Third, unilateral and bilateral tinnitus were phenotypically distinct, with unilateral tinnitus being characterized by older age, asymmetric hearing, more often wearing one hearing aid, older age at tinnitus onset, shorter tinnitus duration, and higher percentage of time being annoyed by tinnitus. We recommend that careful consideration is given to the definitions of hearing asymmetry and tinnitus spatial perception in order to improve the comparability of findings across studies.

    PMID: 24145259 MyJurnal
    Hearing impairment in adolescents is a major public health problem. According to the World Health Organization (WHO) deafness and hearing impairment are common health problems throughout the world. Hearing impairment generally impairs emotional, social, communication and educational function. The aim of this study was to determine the correlation between duration of hearing aid use and improvements in the quality of life. The cross sectional study was conducted at Jalan Peel Primary Special School and Universiti Kebangsaan Malaysia Medical Center (UKMMC) from July 2010 until June 2011. A total of 21 students with hearing impairment involved in this study with mean age of 12.57 (10 to 19 years old). The subjects were divided into 2 groups: first-time hearing aid users and long standing hearing aid users. The hearing assessment was conducted in the first group and hearing aids were fitted. After 1 month hearing aid fitting, the questionnaires were distributed to both groups. Statistical analysis had showed no relation (p>0.05) between duration of hearing aid use and the improvement in the quality of life. However, regardless of the duration of hearing aid usage, there was improvement in the quality of life as shown by the scores of the questionnaires. In conclusion there was no significant relation between duration of hearing aid use and the improvement in the quality of life. Hearing aids were beneficial for hearing loss students regardless of the duration of the hearing aid usage.

    PMID: 33404898 DOI: 10.1007/s10339-020-01010-5
    While previous research has shown that during mental imagery participants look back to areas visited during encoding it is unclear what happens when information presented during encoding is incongruent. To investigate this research question, we presented 30 participants with incongruent audio-visual associations (e.g. the image of a car paired with the sound of a cat) and later asked them to create a congruent mental representation based on the auditory cue (e.g. to create a mental representation of a cat while hearing the sound of a cat). The results revealed that participants spent more time in the areas where they previously saw the object and that incongruent audio-visual information during encoding did not appear to interfere with the generation and maintenance of mental images. This finding suggests that eye movements can be flexibly employed during mental imagery depending on the demands of the task.

    The main objective of the study was to determine the oral health status and possible factors influencing oral hygiene in the institutionalized elderly in Sabah. A cross sectional study in all four institutions for the elderly in QM ii Sabah was conducted using oral examination and interview/questionnaires. Qualitative assessment using Focus Group Discussion was carried out in the caregivers of the institutions. Plaque score was used to assess oral hygiene status. A total of 94.0% of inmates were above 55 years old. There were 13.4 % non-respondents in the total sample of 284. Of the n0n—respondents, 42.4 % had mental disorders and this was statistically signnicant. Of those who responded 34.6% had good 33.3% fair and 32.1% poor oral hygiene. 33.5% were completely edentulous, 86.4% had gingivitis which required scaling, 22.0% had decayed teeth and 54.9% required extraction. Gingivitis, decayed teeth and number of teeth for extraction were signwcantly associated with poor oral hygiene. 14.2% had at least one type of oral disease. Dental abscess was the most common muco»cutaneous lesion found. Mental disorders showed a trend towards poor oral hygiene and this was statistically signyicant. Although 40.8% had physical handicap, 23.3% visual impairment and 8.2% hearing impairment, there was no significant association with oral hygiene status. In conclusion, oral health status of the population is poor and treatment needs are high. Although there was high objective need for oral care (88.6%), perceived need was low (32.0%).

  16. The performance of distortion product otoacoustic emissions and automated auditory brainstem response in the same ear of the babies in neonatal unit
    Abdul Wahid SN, Md Daud MK, Sidek D, Abd Rahman N, Mansor S, Zakaria MN
    Int J Pediatr Otorhinolaryngol, 2012 Sep;76(9):1366-9.
    PMID: 22770594 DOI: 10.1016/j.ijporl.2012.06.008
    OBJECTIVE: To identify the outcomes of hearing screening using different protocols of both Distortion Product Otoacoustic Emissions (DPOAE) and Automated Auditory Brainstem Response (AABR) tests in the same ear of the babies in a neonatal unit population.
    METHODS: A cross-sectional study was carried out on babies who were admitted into a neonatal unit. By using a formula of single proportion and considering 20% drop out, the number of sample required was 114. The subjects were chosen by using a systematic random sampling. The infants selected were subjected to DPOAE followed by AABR tests screening at the same setting before discharge.
    RESULTS: There were 73 newborns (61.6% male and 38.4% female) participated in this study with a total of 146 ears screened. Ototoxic medication was the most common risk factor followed by hyperbilirubinaemia and low birth weight. AABR had higher passing rate (82.9%) as compared to DPOAE (77.4%). The highest passing rate was achieved if the protocol of either passed DPOAE or AABR was used (90.4%). The rate was lower when auditory neuropathy spectrum disorder (ANSD) has been considered (82.9%). Hyperbilirubinaemia, prematurity, craniofacial malformation and ototoxic drugs seem to be the high risk factors for auditory neuropathy.
    CONCLUSION: AABR has a higher passing rate as compared to DPOAE. However, the use of both instruments in the screening process especially in NICU will be useful to determine the infants with ANSD who may need different approach to management. Therefore, a protocol in which newborns are tested with AABR first and then followed by DPOAE on those who fail the AABR is recommended.

    The paper writes on the possible origin of off-limit cases found in a noise project conducted internally in a factory in Malaysia. Out of 691 sampled workers’ that attended audiometric test results (some repeated), it was found that the mode of hearing ability is between 20 to 30 dB depending on individual worker’s age ranging from 20 to 55 years. Out of the total results, approximately 100 workers are above a limit defined here in this paper as the off-limit condition. The chance of a worker originating from a good condition to an unhealthy condition is about 1 percent. The data are tabulated to show that a sway pattern could be an explanation of workers’ origin. Although the data is profound, there is no evidence of a trace due to a short test period. Possibilities are highlight here to outline the severity of a cross over to the unhealthy condition (here defined as the off-limit condition). Some advises are mentioned here with individual susceptibility on the matter though there is no data to substantiate. Further findings are required to show a trace. In conclusion, the severity is highlight. A chart, developed to know the limits of hearing ability, is illustrated ased the findings.

  19. Fulltext The noise exposed factory workers: the prevalence of sensori-neural hearing loss and their use of personal hearing protection devices
    Maisarah SZ, Said H
    Med J Malaysia, 1993 Sep;48(3):280-5.
    PMID: 8183139
    A total of 524 industrial workers were studied. They consisted of 442 noise exposed and 82 non-noise exposed workers. The purpose was to compare the prevalence of sensori-neural hearing loss among the noise exposed and the non-noise exposed workers, to study their knowledge on the hazard of noise to hearing and the workers' attitude towards the hearing protection devices. The prevalence of sensori-neural hearing loss was significantly higher among the noise exposed workers, i.e., 83% versus 31.7% (p < 0.01). However, the prevalence of hearing impairment was much lower for both groups, being 30.1% for the noise exposed and 3.7% for the non-noise exposed group. Although hearing protection devices were provided to 80.5% of the workers, only 5.1% were wearing them regularly. The possibility of developing hearing loss due to exposure to excessive noise was only known by 35.5% of the noise exposed workers. This awareness was found to have a positive correlation with the workers' compliance to the hearing protection devices. Our findings highlight the need for workers to be educated on the hazards of excessive noise exposure to hearing.
