Abstract
Introduction Hearing loss is defined as the partial or total reduction in auditory acuity. Hearing loss can cause detrimental effects on speech, language, developmental, educational, and cognitive outcomes in children. This study aimed to find out the prevalence of hearing loss among children visiting the Department of Otolaryngology and HNS of a tertiary care centre. Methods A descriptive cross-sectional study was conducted among children visiting the Department of Otolaryngology and HNS between 1 January 2022 and 31 December 2022 after obtaining ethical approval. All the patients who underwent pure tone evaluation were included in the study. A convenience sampling technique was used. The point estimate was calculated at a 95% Confidence Interval. Results Among 3051 children, 328 (10.75%) (9.65-11.85, 95% Confidence Interval) had hearing loss. Among children with hearing loss, 170 (51.83%) of children were female. The mean age of children with hearing loss was 13.31±3.39 years. The mean pure tone average among 452 ears with hearing loss was 44.60±17.71 dB. The commonest degree of hearing loss was mild hearing loss 266 (58.85%), and the commonest type was conductive hearing loss 310 (68.58%). Among children with hearing loss, 124 (37.80%) had bilateral hearing loss. Conclusions The prevalence of hearing loss among children visiting the Department of Otolaryngology and HNS was found to be lower than similar studies done in similar settings. Keywords audiology; audiometry; hearing loss; outpatients; prevalence.

Abstract
Background: Many indigenous peoples are at elevated risk for otitis media, however there is limited information on hearing loss due to OM in these communities. An Indigenous Filipino community that has previously been described with an elevated prevalence of OM that is due to rare A2ML1 variants and a common FUT2 variant underwent additional phenological testing. In this study, we describe the audiologic profiles in A2ML1- and FUT2-related otitis media and the validity of otoscopy and genotyping for A2ML1 and FUT2 variants in screening for otitis media and hearing loss. Method: We analyzed A2ML1 and FUT2 genotypes together with demographic, otologic and audiologic data from tympanometry and hearing level assessments of 109 indigenous individuals. Results: We confirmed previous findings of a spectrum of nonsyndromic otitis media as associated with A2ML1 variants. A2ML1 and FUT2 variants were associated with high-frequency hearing loss at 4000 Hz. As expected, young age was associated with flat tympanograms, and eardrum perforations due to chronic otitis media were associated with severe-to-profound hearing loss across frequencies. Adding A2ML1 or FUT2 genotypes improved the validity of otoscopy as a screening test to rule out moderate-to-profound hearing loss. Conclusion: Continued multi-disciplinary management and audiologic follow-up using tympanometry and screening audiometry are needed to document and treat otitis media and prevent permanent hearing loss in the indigenous community.

Abstract
INTRODUCTION Despite the introduction of effective pneumococcal conjugate vaccines (PCV), Streptococcus pneumoniae remains a major cause of acute otitis media (AOM) worldwide. New, higher valency vaccines that offer broader serotype coverage have been recently developed and others are in development. However, given the capsular serotypes expressed by pneumococci causing AOM, it is unclear to what extent differing or higher valency PCVs will provide additional protection. AREAS COVERED We conducted a systematic literature search of the MEDLINE database to identify articles published from January 2016 to September 2021 in 4 low and middle income and 10 high-income countries. We searched PubMed with terms: (Streptococcus pneumoniae) OR pneumococcal AND serotype AND (conjugate vaccine). We evaluated serotype distribution and the actual or projected coverage of pneumococcal serotypes by PCV10 (GlaxoSmithKline), PCV13 (Pfizer), PCV10SII (Serum Institute of India) PCV15 (Merck) and PCV20 (Pfizer). EXPERT OPINION Our review highlights the important epidemiological differences in serotype distribution and coverage by existing and higher valency vaccines to protect against AOM in children. These data provide support for further evaluation of serotype-independent vaccines for optimal control of pneumococcal AOM disease worldwide.

Abstract
While a comprehensive booth audiogram is the gold standard for diagnosis of hearing loss, access to this may not be available in remote and low resource settings. The aims of this study were to validate a tablet-based audiometer in a tertiary medical center in India and explore its capacity in improving access to hearing healthcare. Subjects presenting to Ear-Nose-Throat clinics for conventional booth audiometry testing were recruited for subsequent tablet-based audiometric testing. Testing with the tablet was conducted in a non-sound-treated hospital clinic room. Bilateral air and bone conduction hearing threshold data from 250 through 4000 Hz were validated against conventional booth audiometry. In addition, a small feasibility study was conducted in rural clinics. 70 participants (37 adults and 33 children between the ages 5-18) were assessed. 69% were male, with a mean age of 29.7 years. Sensitivity and specificity for the tablet were 89% (95% CI 80-94%) and 70% (95% CI 56-82%), respectively. While median differences in air conduction thresholds between conventional and tablet audiograms showed statistical significance at 250, 500, and 1000 Hz (p < 0.001), the threshold results of the tablet audiometer were within 5 dB of the conventional audiogram and not clinically significant. Ten patients were successfully screened in rural clinics with tablet audiometry. Tablet portable audiometry is a valid tool for air and bone conduction threshold assessment outside of conventional sound booths. It can accurately identify hearing impairment and offers a screening tool for hearing loss in low resource settings.

Abstract
BACKGROUND In low- and middle-income countries (LMICs), where universal newborn hearing screening programmes are often not available, school entry hearing screening programmes serve as a safeguard for early detection and intervention for hearing loss in school learners. OBJECTIVE To determine a contextually appropriate school entry hearing screening protocol for LMICs. METHODS A scoping review was utilised to comprehensively search for relevant publications in the following electronic databases: Africa-Wide Information, CINAHL, Health Source: Nursing/Academic Edition, Cochrane Library, Pubmed, Scopus, and Web of Science. Studies included those that investigated school-based hearing screening protocols or programmes for LMICs among learners aged five to twelve years. The review was conducted and reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews checklist. RESULTS The search yielded 1863 studies, and after removing duplicates and ineligible studies, 19 studies were selected for data extraction. Pure tone audiometry screening was the most frequently used age-appropriate hearing screening test in the reviewed studies (n = 17). Conducting pure tone audiometry screening using 1, 2, and 4 kHz frequency combination resulted in referral rates ranging from 3.2% to 21%. In studies that included 0.5 kHz to the screening frequencies, referral rates ranged from 5.8% to 56%. Screening at 25 dB HL intensity level yielded referral rates ranging from 3.2% to 10.3%. Immediate rescreening reduced overall referral rates for learners referred for audiological diagnostic testing by up to 57%. Ambient noise levels were controlled by conducting screening in quiet rooms (n = 14) and utilising screening equipment that allows for monitoring and reducing environmental noise (n = 3). CONCLUSION An ideal school entry hearing screening protocol in LMIC contexts could potentially utilise pure tone audiometry screening at 1, 2, and 4 kHz, using 25 dB HL screening intensity level with an immediate rescreen for learners with a refer result. School entry hearing screening should be conducted in a quiet room, preferably using hearing screening equipment capable of monitoring ambient noise levels to reduce false positive referrals.

Abstract
Background Despite abundant literature, a clear and coherent understanding of hearing loss (HL) in India is limited by the wide disparity in studies. Methods We did a review of published peer-reviewed journal articles. Studies reporting the prevalence and degree of HL in India from 1980 to 2020 were included. Information was gathered on the population characteristics, methodology applied and the prevalence of hearing impairment. The data were analysed to identify trends and at-risk sections of population in various categories. Results Four hundred and forty studies were identified after a database search; 29 full-length articles were selected for final analysis. Using a 3-step screening protocol, hearing impairment (abnormal auditory brainstem response/auditory steady state response) in neonates ranged between 1.59 and 8.8 per 1000 births. Among 'at risk' neonates, it ranged from 7 to 49.18 per 1000 births. In children the prevalence of HL was 6.6% to 16.47%. Otitis media was the most common cause of HL in children. Community-based studies (all ages) reported prevalence of HL between 6% and 26.9% and prevalence of disabling HL between 4.5% and 18.3%. Rural areas and elderly showed a higher prevalence of hearing impairment. Conclusion Despite India's improving health indices, hearing disability remains persistently high. It is a major contributor to the loss of personal potential and a financial strain for the individual and the country. A large-scale multicentric study to identify the degree and type of HL, social awareness campaigns, widespread neonatal screening, strengthening treatment facilities and well-funded rehabilitation programmes can counter the rising prevalence of hearing impairment.

Abstract
(1) Background: The purpose of this study was to assess the prevalence of hearing loss in school-age children from rural and urban areas of mid-eastern Poland using standard audiological tests-pure tone audiometry (PTA), impedance audiometry (IA), and otoacoustic emissions (OAEs). (2) Methods: Data were collected from a group of 250 children aged 8 to 13, made up of 122 children from urban areas and 128 children from rural areas of mid-eastern Poland. Hearing was assessed in each of the subjects by means of PTA, IA (tympanometry), and transient-evoked OAEs (TEOAEs). Otoscopy was also performed. (3) Results: There were significantly fewer abnormal results in children from urban than rural areas: they were, respectively, 10.1% and 23.1% for IA, 3% and 9.7% for PTA, and 17.3% and 31.8% for TEOAEs. For hearing-impaired ears in rural areas (failed TEOAE), hearing thresholds were, on average, 11.5 dB higher at 0.5 kHz than for children in urban areas. Comparison of each PTA result with the corresponding IA showed that all cases of hearing loss were related to malfunction of the middle ear. (4) Conclusions: The results of all three hearing tests were significantly worse in children from rural areas compared to those from urban areas. This indicates that audiological healthcare in rural areas needs improvement and that universal hearing screening programs for school-age children would be helpful.

Abstract
OBJECTIVES The main objective of this study is to identify the prevalence of hearing loss in school aged children of Nepal. METHODS This cross-sectional study was carried out on school aged children attending the government run schools of Nepal. A total of 79,340 children from grades 1 through 10 were included in the study. After taking brief history about ear diseases and hearing loss, children were screened for ear diseases in their respective classroom by otoscope. Hearing evaluation was carried out by pure tone audiometer and hearing threshold was obtained at 0.5-4 kHz. The results were then documented and analyzed. RESULTS The prevalence of hearing impairment in school aged children in Nepal is found to be 5.73% (4551 of 79,340). Conductive hearing loss was the most common type of hearing loss and was observed in 70.47% (n = 3207) of the children. CONCLUSIONS This study shows that hearing loss is a common problem in children of Nepal. With the main cause of hearing loss due to preventable conditions such as chronic otitis media, it is believed that early standardized screening, detection and timely management of chronic otitis media in these children can prevent hearing loss and its impact on their educational, social and language development. School based ear health programs are a useful community-oriented solution for prevention of deafness. It shows how important it is to introduce hearing screening for primary school aged children to prevent hearing loss.

Abstract
OBJECTIVE To describe the profile of patients attending the Queen Elizabeth Central Hospital (QECH) audiology clinic in Malawi, over a two-year period (2016-2017). DESIGN A retrospective patient record review. STUDY SAMPLE There were 2299 patients assessed at the QECH audiology department between January 2016 and December 2017. Adult patients' ages ranged from 18 to 94 years (M = 45.8, SD = 19.22). The mean age of children included in this study was 7.7 years (SD= 5.21). Overall, 45.4% of patients were female. RESULTS Of the 61.6% of adults and 41.7% of children found to have some degree of hearing loss, 28.3% and 15.4% were fitted with hearing aids, respectively. The number of patients seen in 2017 (n = 1385) was 34% higher than that of 2016 (n = 914). CONCLUSION This study found that demand for hearing services is increasing in this public sector Malawian audiology department but uptake of hearing aids for those in need is low. Future evaluation of service provision and treatment outcomes is needed. Results from this study can be used to inform the development of future audiology clinics in low resource settings.

Abstract
BACKGROUND Otitis media, a disease highly prevalent among children worldwide, manifests clinically in both acute and chronic forms. The manner and time at which chronicity develops among Indian children is unknown. AIM To study the prevalence, manifestations and risk factors for otitis media in a birth cohort aged 8 years. METHODS A birth cohort of 107 babies was followed up at 8 years of age and ENT evaluation with nasopharyngeal swabbing for detecting Streptococcus pneumoniae and Hemophilus influenzae was performed. RESULTS The overall prevalence of otitis media was 14%, almost half the prevalence in the first 2 years of life. Eight children (7.5%) with congested, bulging eardrums and no systemic symptoms had asymptomatic acute otitis media. Another five (4.7%) children had otitis media with effusion and 2 (1.9%) had chronic suppurative otitis media. Although 10/15 (66.7%) children with otitis media had positive swabs at 8 years age, only 2 were pneumococcal vaccine (PCV-13) serotypes. Risk factor analysis showed that passive smoking was the only significant parameter associated with otitis media (p = 0.029). Nasopharyngeal swabbing showed that 51/105 (48.6%) children had positive swabs for S. pneumoniae and 5/105 (4.8%) for S.pneumoniae with non-type b H. influenzae. The ten most commonly encountered pneumococcal serotypes were 6A,4,8,16F,33B,35A,35B, 18C, 19F and 23B which together comprised 29 of the 56 (51.8%) isolates. PCV-13 serotypes formed 19/56 (33.9%) to 21/56 (37.5%) of all pneumococcal isolates. Of 6 children who had received PCV-13, 4 tested positive for S. pneumoniae at 8 years of age too. However, none were vaccine serotypes. Four of those with otitis media who had positive swabs had received no immunisation at all and 3 of them had vaccine serotypes, viz. 4, 6A and 18C respectively. CONCLUSION Indian children continue to have a high prevalence of otitis media at 8 years age. More than 1/3 of nasopharyngeal isolates at this age are vaccine serotypes. Passive smoking is an important risk factor for childhood otitis media and may contribute to the development of chronicity of the disease.

Abstract
Objectives Hearing impairment and ear diseases are among the world's leading causes of years lived with disability. Ear disorders are a major health problem in developing countries like India. The present research had been planned to screen the primary school children for ear morbidity and to study the various factors associated with ear morbidities so that corrective intervention can be initiated at the earliest. Methods A cross-sectional study was conducted among all primary school children of two schools in Aliganj, Delhi. Complete enumeration of all the school children of these two primary schools was planned for this study. Modified version of World Health Organization's (WHO's) "Ten Question Plus" screening instrument was used, followed by Otoscopy examination, in all children for confirmation of ear disease, if any. Descriptive data analysis was performed. Results Out of the total 430 study subjects, ear morbidities were found in 198 (46.0%) study participants. Presence of ear morbidity showed significant association with overcrowding, absence of a separate kitchen, passive smoking, feeding young child in lying down position, upper respiratory tract infection (URI)˃3 episodes/year and allergy (p<0.05). Conclusions This study has highlighted the need to detect ear diseases at the earliest thereby avoiding complications. The health examination in the schools must include screening students for ear diseases to reduce the burden of hearing disability. Inputs from the study may be used for effective prioritization and planning for prevention and management of ear diseases at the primary school level.

Abstract
Aim: To gauge the prevalence of hearing loss in school children in Bishkek, Kyrgyzstan, and refer pupils with positive results for further diagnostic testing. Background: According to WHO data, hearing disorders are common in school-age children. Screening for hearing loss is an important preventative tool, helping to avoid further complications. Expenditure that supports early child development can reduce future outlay on health care and social services; it can eliminate disability problems, education deficits, and social maladaptation in later adult life. Methods: Pure-tone air-conduction hearing thresholds were obtained at 0.5–8 kHz. The results of the hearing screening examination were regarded as positive if pure-tone thresholds were higher than 20 dB HL in one or both ears at one or more of the test frequencies. Data were also obtained from follow-up visits of children who failed the initial screening. Findings: This study included 452 children aged 7–13 years old. Based on audiograms, screening showed that 123 (27.2%) of the children had hearing impairment. The study has important implications for clinical practice and health policy. There is a need for systematic monitoring of hearing status among children of this age, and parents and educators need to be made aware of the significance of hearing loss.

Abstract
Objective School hearing screening may mitigate the effects of childhood hearing loss through early identification and intervention. This study provides an overview of existing school hearing screening programs around the world, identifies gaps in the literature, and develops priorities for future research. Data Sources A structured search of the PubMed, Embase, and Cochrane Library databases. Review Methods A total of 65 articles were included according to predefined inclusion criteria. Parameters of interest included age groups screened, audiometric protocols, referral criteria, use of adjunct screening tests, rescreening procedures, hearing loss prevalence, screening test sensitivity and specificity, and loss to follow-up. Conclusions School hearing screening is mandated in few regions worldwide, and there is little accountability regarding whether testing is performed. Screening protocols differ in terms of screening tests included and thresholds used. The most common protocols included a mix of pure tone screening (0.5, 1, 2, and 4 kHz), otoscopy, and tympanometry. Estimates of region-specific disease prevalence were methodologically inaccurate, and rescreening was poorly addressed. Loss to follow-up was also a ubiquitous concern. Implications for Practice There is an urgent need for standardized school hearing screening protocol guidelines globally, which will facilitate more accurate studies of hearing loss prevalence and determination of screening test sensitivity and specificity. In turn, these steps will increase the robustness with which we can study the effects of screening and treatment interventions, and they will support the development of guidelines on the screening, diagnostic, and rehabilitation services needed to reduce the impact of childhood hearing loss.

Abstract
OBJECTIVE There are scant recent studies from low middle-income countries that investigate the impact of otitis media (OM) on hearing loss (HL) in school children. METHODS This was a prospective epidemiological survey conducted by otorhinolaryngologists and audiologists in a sample of 7005 public school children (6-15 years) from 6 urban and rural sub-districts, in Indonesia. Children with otoscopic abnormalities or who failed a hearing-screening test conducted at school, underwent diagnostic audiometry and tympanometry. RESULTS OM was detected in 172 children (2.5%), acute otitis media - AOM (17%), otitis media with effusion - OME (15%), and chronic suppurative otitis media - CSOM (67%). The overall rate of HL in the school children was 181/10,000, which was almost three-fold higher in rural (273/10,000) than urban areas 92.6/10,000. OME accounted for much of the mild HL, while CSOM accounted for most of the moderate HL. There was a significantly higher rate of OM related HL in rural areas (116.2/10,000), than in urban areas (47.4/10,000), p = 0.002. OM related disabling HL was found at a rate of 44.2/10,000, mostly due to CSOM (37.1/10,000). CONCLUSION Otitis media contributed to 57% of all HL in school children, and posed a significant burden on Indonesian school children. Most of the disabling HL was due to CSOM. Efforts to find these children and offer ear and hearing care are important.

Abstract
This paper explores the validity (sensitivity and specificity) of different cut-off levels of the UNICEF/Washington Group Child Functioning Module (CFM) and the inter-rater reliability between teachers and parents as proxy respondents, for disaggregating Fiji's education management information system (EMIS) by disability. The method used was a cross-sectional diagnostic accuracy study comparing CFM items to standard clinical assessments for 472 primary school aged students in Fiji. Whilst previous domain-specific results showed "good" to "excellent" accuracy of the CFM domains seeing, hearing, walking and speaking, newer analysis shows only "fair" to "poor" accuracy of the cognitive domains (learning, remembering and focusing attention) and "fair" of the overall CFM (area under the Receiver Operating Characteristic curve: 0.763 parent responses, 0.786 teacher responses). Severe impairments are reported relatively evenly across CFM response categories "some difficulty", "a lot of difficulty" and "cannot do at all". Most moderate impairments are reported as "some difficulty". The CFM provides a core component of data required for disaggregating Fiji's EMIS by disability. However, choice of cut-off level and mixture of impairment severity reported across response categories are challenges. The CFM alone is not accurate enough to determine funding eligibility. For identifying children with disabilities, the CFM should be part of a broader data collection including learning and support needs data and undertaking eligibility verification visits.

Prevalence of ear disease and associated hearing loss among primary school students in the Solomon Islands: Otitis media still a major public health issue. Int J Pediatr Otorhinolaryngol 2018; 113:223-228. [PMID: 30173991 DOI: 10.1016/j.ijporl.2018.08.004] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2018] [Revised: 08/03/2018] [Accepted: 08/04/2018] [Indexed: 10/28/2022]
Abstract
OBJECTIVE The present study aimed to assess the prevalence of otitis media and associated hearing loss among primary school students in the Solomon Islands. METHODS A total of 604 primary school students (280 males, 324 females) aged 4-15 years were assessed in two primary schools (government, nongovernment) in the capital city Honiara. School-based ear examinations were performed, including otoscopy and tuning-fork tests. Students were referred to the ENT Clinic for medical intervention and/or pure-tone audiometry assessment. RESULTS A total of 342 students (56.6%) did not pass their ear examination, with a significantly higher fail rate among younger students (p < 0.001). The most common ear pathology was Otitis Media with Effusion (OME) (34.2%), followed by impacted wax (22.8%), and Chronic Suppurative Otitis Media (3.1%). The follow-up attendance rate at the ENT Clinic was 81.1%. Among students with OME in at least one ear, 50% failed audiometry screening in the affected ear. While age was a significant factor for OME, it was not a significant factor for OME-associated hearing loss. CONCLUSIONS Ear diseases with associated hearing loss are a significant public health problem among primary school students in the Solomon Islands. The implementation of routine School Ear and Hearing Programs could be beneficial, and should reduce the national burden of ear diseases.

Abstract
OBJECTIVE Childhood hearing impairment (CHI) is a major developmental disability, but data at the national level are limited, especially those on different severities. We conducted a study to fill this data gap. DESIGN A nationwide study on the basis of a reporting system. SETTING To provide services to disabled citizens, the Taiwanese government maintains a registry of certified cases. Using data from this registry, we estimated prevalence rates of CHI of different severities from 2004 to 2010 and made comparisons between urban and rural areas. PARTICIPANTS Taiwanese citizens ≤17 years old. PRIMARY OUTCOME MEASURES To qualify for CHI disability benefits, a child must have an unaided pure-tone better ear hearing level at 0.5, 1 and 2 kHz with an average ≥55 decibels (dB), confirmed by an otolaryngologist. The severity was classified by pure-tone better ear hearing level as mild (55-69 dB), moderate (70-89 dB) and severe (≥90 dB). RESULTS The registered cases under 17 years old decreased annually from 4075 in 2004 to 3533 in 2010, but changes in the prevalence rate were small, ranging from 7.62/10 000 in 2004 to 7.91/10 000 in 2006. The prevalence rates of mild CHI increased in all areas over time, but not those of moderate or severe CHI. Rural areas had higher overall prevalence rates than urban areas in all years, with rate ratios (RRs) between 1.01 and 1.09. By severity, rural areas had higher prevalence rates of mild (RRs between 1.08 and 1.25) and moderate (RRs between 1.06 and 1.21) CHI but had lower prevalence rates of severe CHI (RRs between 0.92 and 0.99). CONCLUSION While rural areas had higher overall prevalence rates of CHI than urban areas, the RRs decreased with CHI severity. Further studies that identify factors affecting the rural-urban difference might help the prevention of CHI.

Abstract
PURPOSE This study investigated the seeing, hearing and walking questions of the UNICEF/Washington Group Child Functioning Module and the inter-rater reliability between teachers and parents as proxy respondents. METHODS Cross-sectional diagnostic accuracy study, two-gate design with representative sampling, comparing Module responses to reference standard assessments for 472 primary aged students in Fiji. Receiver operating characteristic curves were constructed to determine the area under the curve and optimal cut-off points. RESULTS Areas under the curves ranged from 0.823 to 0.889 indicating "good" diagnostic accuracy. Inter-rater reliability between parent and teacher responses was "good" to "excellent". The optimal cut-off determined by the Youden Index was "some difficulty" however a wide spread of impairment levels were found in this category with most children either having none or substantial impairments. CONCLUSIONS The diagnostic accuracy of the Module seeing, hearing and walking questions appears acceptable with either parents or teachers as proxy respondents. For education systems, use of the cut-off "some difficulty" with accompanying clinical assessment may be important to capture children who require services and learning supports and avoid potentially misleading categorization. Given the high proportion of the sample from special schools research is required to further test the Module in mainstream schools. Implications for rehabilitation Identification of children who are at risk of disability in Fiji is important to enable planning, monitoring and evaluating access to quality inclusive education. The UNICEF/Washington Group Child Functioning Module appears to be a practical and effective tool that can be used by teachers to identify children at risk of disability. Children identified on the UNICEF/Washington Group Child Functioning Module as having "some difficulty" or higher levels of difficulty in relation to vision, hearing or walking should be referred for further assessment and services. Rehabilitation services in Fiji need to prepare for greater numbers of referrals as the Ministry of Education increasingly rolls out the inclusive education policy, which includes identification by schools of children at risk of disability.

Abstract
OBJECTIVE This study aimed to describe the prevalence and characteristics of hearing loss in school-aged children in an urban South African population. METHOD Children from grade one to three from five schools in the Gauteng Province of South Africa formed a representative sample for this study. All children underwent otoscopic examinations, tympanometry and pure tone screening (25dB HL at 1, 2 and 4kHz). Children who failed the screening test and 5% of those who passed the screening test underwent diagnostic audiometry. RESULTS A total of 1070 children were screened. Otoscopic examinations revealed that a total of 6.6% ears had cerumen and 7.5% of ears presented with a type-B tympanogram. 24 children (12 male, 12 female) were diagnosed with hearing loss. The overall prevalence of hearing loss was 2.2% with Caucasian children being 2.9 times more (95% confidence interval, 1.2-6.9) likely to have a hearing loss than African children. CONCLUSION Hearing loss prevalence in urban South African school-aged children suggest that many children (2.2%) are in need of some form of follow-up services, most for medical intervention (1.2%) with a smaller population requiring audiological intervention (0.4%).

Abstract
In order to study the epidemiology of acute otitis media (AOM) and Streptococcus pneumoniae nasopharyngeal colonization in the first 2 years of life, we followed up an unvaccinated birth cohort monthly and at visits when sick, with otoscopy to detect AOM and performed nasopharyngeal swabbing to detect S. pneumoniae. Serotyping of positive cultures was also performed. Of 210 babies who were enrolled at birth, 61 (29·05%) experienced 128 episodes of AOM [relative risk 2·63, 95% confidence interval (CI) 1·21-5·75] with maximum incidence in the second half of the first year of life. Episodes ranged from 1 to 7 (mean 2·1 episodes). Most (86·9%) babies with AOM had a positive culture swab giving an odds ratio (OR) of 1·93 (95% CI 1·03-3·62, P = 0·041) for this association. Other risk factors identified for AOM were winter season (OR 3·46, 95% CI 1·56-7·30, P = 0·001), upper respiratory infection (OR 2·43, 95% CI 1·43-4·51, P = 0·005); residents of small households were less likely to develop AOM (OR 0·32, 95% CI 0·17-0·57, P < 0·01). Common S. pneumoniae serotypes isolated during episodes were 19, 6, 15, 35, 7, 23, 9 and 10 which indicated a theoretical coverage for pneumococcal vaccines PCV10 and PCV13 constituent serotypes of 62·8%. We conclude that AOM in Indian infants is often associated with S. pneumoniae colonization of the nasopharynx as well as other risk factors.

Abstract
BACKGROUND Chronic suppurative otitis media (CSOM) is one of the leading causes of preventable disabling hearing impairment (DHI) in developing countries. Early detection and management complements advances made in other survival programs, improves work capacity, and enhances learning opportunities for school children. We aimed to determine the prevalence of CSOM and associated DHI among school children aged six to 16 years in Socotra Island, Yemen. METHODS We conducted a cross-sectional community-based survey, from 20 April 2011 to 20 June 2011. The study procedures involved completing a questionnaire, an otoscopic ear examination, an audiometric test of hearing, and tuning fork tests for the type of DHI. RESULTS A total of 686 children were interviewed and examined for CSOM and associated DHI of CSOM cases. The prevalence of CSOM was 7.4%, (95% CI 5.5-9.4). CSOM status was significantly associated with DHI (p=0.001), but no significant associations were found between demographic characteristics and CSOM status. Logistic regression identified four significant independent contributing factors: history of ear discharge in the last 12 months (odds ratio (OR) 7.8, 95% CI 3.9-15.6); swimming in local pools (OR 6.0, 95% CI 1.4-25.4); recurrent respiratory tract infection more than three times per year (OR 5.3, 95% CI 2.5-11.0); and overcrowding with more than three families per house (OR 4.4, 95% CI 1.7-11.5). . CONCLUSION The burden of CSOM in the children studied indicates a high level of DHI in these communities within Yemen. A history of ear discharge, swimming in local pools, recurrent respiratory infections, and overcrowded housing were the strongest predictors for CSOM. There is a need for better ear care and screening programs for early detection and management of this disease.

Abstract
AbstractObjective:This study aimed to assess the prevalence and profile of ear diseases in children from Delhi, India.Methods:A population-based cross-sectional door-to-door survey was carried out in two districts of Delhi, and involved children of all demographic sections of the region. A total of 4626 children aged between 18 days and 15 years underwent examinations including otoscopy, impedance audiometry and hearing screening.Results:In all, 14.8 per cent of the study sample was diagnosed with one or more ear morbidities, the most common being cerumen impaction (7.5 per cent) and chronic suppurative otitis media (3.6 per cent). There was clinical evidence of otitis media with effusion in 2 per cent of children, and 0.96 per cent had otitis externa (bacterial and fungal). The point prevalence of acute suppurative otitis media was 0.39 per cent. In all, 0.45 per cent of children were found to have an undiagnosed foreign body within the ear canal.Conclusion:The high prevalence of ear disease poses a significant public health problem in Delhi.

Abstract
BACKGROUND Although the epidemiology of otitis media is well-known in industrialized countries, the extent of otitis media in developing Asian countries, especially in south East Asia is not well studied. METHODS To define the burden of otitis media and its sequelae in children 6-15 years of age, we enrolled elementary and junior high school children in 6 areas in rural and urban Indonesia. Randomly selected schools and classrooms were selected. All children were administered a questionnaire and had ear examinations, pneumatic otoscopy and screening audiometry. Children with any abnormality on examination or with a relevant history underwent diagnostic audiometry and tympanometry, if indicated. RESULTS Of the 7005 children studied, 116 had chronic suppurative otitis media (CSOM), 30 had acute otitis media and 26 had otitis media with effusion. 2.7% of rural children had CSOM compared with 0.7% of urban children (P < 0.0001). The rates per 1000 of CSOM in rural Bali and Bandung were significantly higher (75 and 25, respectively) than in the rest of Indonesia (P < 0.05). In rural Bali, the rate per 1000 children of inactive CSOM was 63 in 6- to 9-year-old children, compared with 37 in children aged 13-15 years. Concomitantly, the rates of tympanosclerosis were 7 and 26/1000, respectively, in these age groups. CONCLUSIONS In Indonesia, the prevalence of CSOM is relatively high with most disease occurring in rural areas. The high rates in rural Bali with early progression to tympanosclerosis suggest a significant burden of potentially vaccine preventable illness.

Abstract
BACKGROUND Excessive ambient noise in school settings is a major concern for school hearing screening as it typically masks pure tone test stimuli (particularly 500 Hz and below). This results in false positive findings and subsequent unnecessary follow-up. With advances in technology, noise-cancelling headphones have been developed that reduce low frequency noise by superimposing an anti-phase signal onto the primary noise. This research study examined the utility of noise-cancelling headphone technology in a school hearing screening environment. METHODS The present study compared the audiometric screening results obtained from two air-conduction transducers-Sennheiser PXC450 noise-cancelling circumaural headphones (NC headphones) and conventional TDH-39 supra-aural earphones. Pure-tone hearing screening results (500 Hz to 4000 Hz, at 30 dB HL and 25 dB HL) were obtained from 232 school children, aged 6 to 8 years, in four Hong Kong primary schools. RESULTS Screening outcomes revealed significant differences in referral rates between TDH-39 earphones and NC headphones for both 30 dB HL and 25 dB HL criteria, regardless of the inclusion or exclusion of 500 Hz results. The kappa observed agreement (OA) showed that at both screening intensities, the transducers' referral agreement value for the 500 Hz inclusion group was smaller than for the 500 Hz exclusion group. Individual frequency analysis showed that the two transducers screened similarly at 1000 Hz and 2000 Hz at 25 dB HL, as well as at both 30 dB HL and 25 dB HL screening levels for 4000 Hz. Statistically significant differences were found for 500 Hz at 30 dB HL and at 25 dB HL, and for 1000 Hz and 2000 Hz at 30 dB HL. OA for individual frequencies showed weaker intra-frequency agreement between the two transducers at 500 Hz at both intensity criterion levels than at higher frequencies. CONCLUSIONS NC headphones screening results differed from those obtained from TDH-39 earphones, with lower referral rates at 500 Hz, particularly at the 25 dB HL criterion level. Therefore, NC headphones may be able to operate at lower screening intensities and subsequently increase pure-tone screening test sensitivity, without compromising specificity. NC headphones show some promise as possible replacements for conventional earphones in school hearing screening programs.

Abstract
BACKGROUND There is a considerable scarcity of reliable population-based data on the prevalence of preventable ear disorders in developing countries. This study was conducted to determine the prevalence of preventable ear disorders in primary school children (aged 5 to 12 years) in northern India. METHOD A pro forma questionnaire was used to screen 15 718 primary school children in New Delhi for ear disorders. Ear examinations were conducted using otoscopy and impedance audiometry. RESULTS Impacted cerumen was prevalent in 7.93 per cent of schoolchildren, 4.79 per cent suffered from chronic otitis media and 3.06 per cent suffered from otitis media with effusion. Acute otitis media was detected in 0.65 per cent and foreign bodies were found in 0.34 per cent of the children. CONCLUSION Preventable ear diseases posed a significant health problem among children at primary school level. Regular screening of children during this stage would ensure that their school lives were not affected by hearing impairments or preventable ear disorders. Information gathered in this study will help in effective treatment prioritisation of ear disorders, planning and resource allocation.

Abstract
BACKGROUND Otitis media (OM) is a leading cause of health care visits and drugs prescription. Its complications and sequelae are important causes of preventable hearing loss, particularly in developing countries. Within the Global Burden of Diseases, Injuries, and Risk Factors Study, for the year 2005 we estimated the incidence of acute OM, chronic suppurative OM, and related hearing loss and mortality for all ages and the 21 WHO regional areas. METHODS We identified risk factors, complications and sequelae of OM. We carried out an extensive literature review (Medline, Embase, Lilacs and Wholis) which lead to the selection of 114 papers comprising relevant data. Data were available from 15 of the 21 WHO regions. To estimate incidence and prevalence for all countries we adopted a two stage approach based on risk factors formulas and regression modelling. RESULTS Acute OM incidence rate is 10.85% i.e. 709 million cases each year with 51% of these occurring in under-fives. Chronic suppurative OM incidence rate is 4.76 ‰ i.e. 31 million cases, with 22.6% of cases occurring annually in under-fives. OM-related hearing impairment has a prevalence of 30.82 per ten-thousand. Each year 21 thousand people die due to complications of OM. CONCLUSIONS Our study is the first attempt to systematically review the available information and provide global estimates for OM and related conditions. The overall burden deriving from AOM, CSOM and their sequelae is considerable, particularly in the first five years of life and in the poorest countries. The findings call for incorporating OM-focused action within preventive and case management strategies, with emphasis on the more affected.

Abstract
Acute otitis media (AOM) is common in Indian children, but there is limited published information on its clinic prevalence, clinicians' diagnostic practices, and their management strategies. We approached 649 ear-nose-throat (ENT) surgeons to assess these aspects of AOM. We conducted the survey between May 2010 and February 2011 with the same set of ENT surgeons practising across India, once each during summer, monsoon and winter, using a validated 36-item questionnaire to record their reflective recall. 78 % (506/649) of approached ENT surgeons responded. The clinic prevalence of AOM was 43 % with peaks reported in July and December. 96 % (486/506) of the surgeons used otoscopy to diagnose AOM. 86 % (435/506) prescribed analgesics, and 89 % (449/506) prescribed decongestants. 98 % (495/506) treated AOM with an antibiotic at initial consultation: amoxicillin/clavulanic acid 78 % (395/506), amoxicillin 29 % (144/506), cefpodoxime 29 % (149/506), cefixime 28 % (141/506) and azithromycin 27 % (134/506). Amoxicillin/clavulanic acid 32 % (162/506) and cefpodoxime 27% (137/506) were mostly prescribed for relapse. The average reported duration of initial antibiotic therapy was 7 days and for relapse was 9 days. The reported clinic prevalence of AOM was higher (43 %) than anticipated (about 10 %) in ENT practice. Almost all the ENT surgeons used an otoscope to diagnose AOM. Amoxicillin/clavulanic acid was the preferred antibiotic for treating AOM either initially or for relapse. Most surgeons also used analgesics and decongestants for symptomatic relief.

Abstract
OBJECTIVE Otitis media with effusion (OME) is a major cause of childhood hearing impairment (HI) in the developing world, but its prevalence has never been quantified in Nepal. This study therefore set out to determine the proportion of cases of OME complicated by HI and to identify associated factors. METHODS This was a cross-sectional prevalence survey carried out in rural, urban and Tibetan schools in and around Pokhara, Nepal. HI was the primary outcome, and was defined as a middle-frequency pure tone average >25 dB on audiological testing. The study population was defined as children aged four years and older, attending primary school and with a diagnosis of OME. RESULTS One hundred and eleven schoolchildren with a combined total of 172 ears affected by OME underwent audiometric assessment. HI was most prevalent in the rural Nepali population; 27% (95%CIs 18-38%) had HI, with a mean hearing loss of 22 dB (15-25 dB). In the Tibetan population, 16% (8-29%) had HI, with a mean loss of 17 dB (12-22 dB). The urban Nepali population had the least HI; 4% (1-13%) were affected, with a mean loss of 16 dB (15-19 dB). The difference in prevalence between the urban and rural Nepali populations was statistically significant (p>0.05). Logistic regression analysis did not identify any associated factors. CONCLUSIONS HI is a common complication of OME in Nepal. There is hitherto-unreported variation between populations in the number of cases of OME complicated by HI. This study identified higher rates of morbidity amongst rural populations but was unable to identify associated factors.

Abstract
AIMS AND OBJECTIVES The main aim of this survey was to assess the prevalence of common ear, nose and throat (ENT) disorders in the rural India. SETTING After initial screening of the patients at the primary health center, a week long camp was organized in a district where entire population resides in the rural area and a complete ENT examination and investigation was done by the ENT specialists. MATERIALS AND METHODS A total of 950 patients were found to be suffering from the ENT ailments in the total population of thirty thousands of the district (4.31%). Out of the total of 950 patients 36.6% of patients (n = 348) had ear problems, 23.57% (n = 225) had nasal problems, while 16.58% (n = 161) of patients were suffering from the throat disorders. Among the ear patients most common diagnosis was chronic suppurative otitis media (CSOM) 114 and presbyacusis 83. Deviated nasal septum and sinusitis was most common diagnosis in nasal symptoms while gastroesophageal reflux (GERD) was the commonest throat problems seen in this study. Eleven patients had various benign tumors of head and neck and only one patient was found to be having oropharyngeal malignancy. The congenital head and neck lesion was seen in only four patients. CONCLUSIONS In this survey 4.31% of the rural population of the district were having ENT ailments. The highest numbers rural population (35.65%) were having ear diseases. This was primarily due to low socioeconomic status and lack of awareness of the population. The nasal problem was seen in 23.57%, while throat problem was seen in 16.58%. The percentage of head neck malignancy in this survey was 0.0028.

Abstract
A cross-sectional survey was conducted among 3646 persons, 15 to 23 years of age, in the southern plains District of Sarlahi, Nepal, to assess the prevalence and severity of hearing loss and middle-ear dysfunction, and adverse effects of hearing loss on social integration. Between 2006 and 2008, subjects were enumerated and underwent otoscopic, tympanometric, and audiometric evaluations at central sites in villages. Hearing loss was diagnosed in subjects who failed a hearing screening and exhibited an average air conduction threshold value greater than or equal to 30 dBHL in the worse ear. Clinically, 32.8% of subjects exhibited a dull or retracted tympanic membrane, and 18% had abnormal tympanometry. Nearly 12% failed the hearing screening test, among whom more than half, or 6.1% overall, had hearing loss. Hearing-impaired subjects were six- to eight-fold (ORs, with 95% CIs excluding 1.0) more likely to report problems in hearing usual sounds or communicating with other people. Among young adults living in southern Nepal, hearing loss is common, and associated with social disability.

Abstract
Purpose
This study examined the feasibility of screening hearing loss in rural and urban schools in Egypt, and investigated the prevalence and causes of hearing impairment (HI) in Egyptian primary-school students.
Method
A total of 555 children (6–12 years of age) from a rural and an urban school in the Shebin El-Kom District of Egypt were screened for HI at their schools. A 2-stage screening procedure was used, and positive cases were referred for a diagnostic hearing assessment at a regional medical facility. Risk factors were investigated through a parent questionnaire and an environmental study consisting of noise, ventilation, and crowding measurements at the schools.
Results
The screening failure rate was 25.6%, and the prevalence of confirmed HI was 20.9%. The rate of HI did not differ across the schools. Conductive hearing loss of minimal to mild severity was the most common type of HI. The most important predictors for HI were parent suspicion, otitis media, household smoking, low socioeconomic status, and postnatal jaundice.
Conclusions
The prevalence of HI did not differ across settings and was more common than reported in children from developed countries. The screening results also suggest that professionals with limited audiology background can be trained to implement hearing screening programs in Egyptian schools.

Abstract
OBJECTIVE To establish the role of various risk factors for otitis media among preschool, rural Indian children. METHODS A cross sectional study of 800 children was undertaken to determine the prevalence of otitis media. Thereafter, using a case control study design, all the cases and an equal number of controls were compared in terms of various common risk factors for otitis media. The 13 risk factors studied were age, sex, socioeconomic status (SES), nutritional status, balwadi attendance, duration of breast feeding, passive smoking, exposure to household smoke, persistent rhinorrhoea,positive throat culture, snoring, seasonal rhinitis and allergic rhinitis. Bivariate association between these risk factors and otitis media was studied using chi-square test of proportions. Multivariate logistic regression analysis was done by including the variables which were significant at p=0.35 in the bivariate analysis. RESULTS From the cross sectional study, the prevalence of otitis media was found to be 8.6%, roughly half the prevalence obtained 10 years previously from the same region. Otitis media with effusion (OME) was the commonest manifestation of otitis media (6%) with 3.8% having bilateral disease. Ear wax was seen in 27.5% of subjects. Eighteen (2.3%) children failed the screening audiometry test set at 40 dB HL. Sociodemographic factors among cases and controls were comparable. The prime risk factors for otitis media identified by bivariate analysis included persistent rhinorrhoea, snoring and seasonal rhinitis. On multivariate logistic regression analysis, persistent rhinorrhoea (p<0.01,O.R.=7.56, 95%C.I. 2.73 - 20.92), snoring (p=0.01,O.R.=4.89, 95% C.I.1.32 - 18.17), seasonal rhinitis(p=0.02, OR=5.93,95% CI=1.33-26.51) and passive smoking (p=0.04, O.R.=3.29, 95%C.I. 1.05-10.33) were found to be important risk factors for otitis media. Age, sex, SES, parental education, seasonal or allergic rhinitis, inadequate breast feeding and exposure to household smoke were not significant risk factors. CONCLUSIONS Otitis media continues to have a high prevalence among South Indian children. Persistent rhinorrhea, snoring, seasonal rhinitis and passive smoking are the chief risk factors for the disease. Measures to reduce the prevalence of otitis media by addressing these risk factors are urgently required.

Abstract
BACKGROUND There is a need to develop affordable but effective audiometric screening equipment, particularly for use in low-income countries. With advances in computer technology, low-cost computer-based audiometer software has been developed. However, the efficacy of computer-based audiometers in hearing screening and diagnostic assessment requires investigation. The purpose of this study was to evaluate the accuracy of a low-cost, computer-based audiometric system in a school-based hearing screening programme. METHODS Eighty children were screened using the computer-based audiometer and with a conventional pure tone screening audiometer. Overall refer rates, as well as frequency and age effects on the accuracy of the computer-based audiometer, were considered. RESULTS There was a significant relationship between the low-cost, computer-based audiometer and a conventional pure tone audiometer when a 40 dBHL refer criterion was used in school hearing screening and when test results at 500 Hz were excluded from analysis. However, background noise effects and software limitations in the computer-based system had major adverse effects on screening performance. CONCLUSIONS The study results and preliminary practical experience with the system suggest that, with further software and hardware improvements, a low-cost, computer-based system may well be feasible for routine school screening in developing countries.

Abstract
OBJECTIVES (a) To study knowledge, attitudes and practices with respect to risk factors of otitis media in a rural South Indian Community where the prevalence of otitis media is high. (b) To discover the association between parental education, socioeconomic status (SES) and family type (nuclear or joint) with knowledge, attitudes and practices regarding risk factors for otitis media. METHODS Using a cluster sampling design, the caregivers of 150 children attending daycare were interviewed to note knowledge, attitudes and practices with respect to risk factors for otitis media. Data on level of education of the caregiver, house type (an indicator of SES) and type of family structure were noted. A questionnaire was administered to collect all the relevant data. Statistical analysis of the data obtained was performed to note frequencies. Correlations between sociodemographic parameters and knowledge, attitudes and practices were studied using Chi-square test of proportions. RESULTS Over 50% of the population showed knowledge deficits with regard to the various risk factors for otitis media. Caregivers from nuclear families were slightly less knowledgeable regarding lack of immunization and household smoke as risk factors for the disease. There was no correlation between any of the sociodemographic factors and attitudes. However, educated mothers were more likely than illiterate mothers to clean their children's ears of wax on a regular basis with the belief that it would prevent ear disease (p=0.05). Treatment practices in the community were more or less uniform in that earache was either disregarded (26.4%) or treated with home remedies (67.2%) by most caregivers, while a doctor's opinion was often sought for ear discharge (50%). Parents of higher SES were more likely to use home remedies than those of lower SES (p=0.008). CONCLUSIONS Sociodemographic factors as well as poor knowledge and attitudes and unhealthy practices with respect to risk factors of otitis media contribute to the high prevalence of otitis media in this rural South Indian community. Health education regarding risk factors and provision of accessible health care is essential to reduce the disease burden.

Adhikari P. Pattern of ear diseases in rural school children: experiences of free health camps in Nepal. Int J Pediatr Otorhinolaryngol 2009; 73:1278-80. [PMID: 19560217 DOI: 10.1016/j.ijporl.2009.05.020] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2009] [Revised: 05/19/2009] [Accepted: 05/28/2009] [Indexed: 10/20/2022]
Abstract
OBJECTIVE This study was done to find out the prevalence of different types of ear disease in rural school children of Nepal. MATERIAL AND METHODS This is a prospective cross-sectional study among 2000 children aged between 5 and 13 years. Children those attending free health camps in rural places of six districts of Nepal were included. These free health camps were organized either by Healthy Human Society (non-governmental organization run by doctors of Nepal) or in association with other organizations. All these children were interviewed and examined otoscopically from January 2006 to December 2008. Informed consent was taken from guardians to participate in this study. Results are expressed in numbers and percentages. RESULTS Out of 2000 children, 64.2% were male and 35.8% female children. The most common ear diseases were wax (62.0%), followed by chronic suppurative otitis media (7.6%) and otitis media with effusion (4.7%). In CSOM, there was 83.0% tubotympanic type. Both the wax and CSOM were common in 5-7 years age group. Overall ear diseases were present in 81.6% children. CONCLUSION Wax followed by chronic suppurative otitis media and otitis media with effusion were the most common ear diseases in rural school children of Nepal. Improvement of socioeconomic status and health care facilities, such as repetitions of free health camps will be helpful in reducing the prevalence of ear diseases.

Abstract
BACKGROUND Hearing loss is a common and considerable disability that harms educational performance of school children in developing countries like Iran. Lack of a simple and practical screening protocol often deters routine and systematic hearing screening at school entry. METHODS This study was to establish a practical screening model for hearing loss in school-aged children based on a community-based, retrospective casecontrol study in Ilam, the capital of Ilam province in Iran. Results from the audiologic and non-audiologic examination of 785 children in primary schools were selected and examined. The non-audiologic evaluation consisted of medical history, general physical examination, while the audiologic assessment consisted of otoscopy, audiometry and tympanometry. RESULTS Univariate analysis of non-audiologic variables showed an association between hearing loss and male gender (P<0.05) and the grade of study (P<0.05). The frequency of impaired hearing in the first grade of primary schools was significantly higher than the children in the second grade (P<0.05). In audiologic factors related to impaired hearing, otitis media with effusion (OME) was diagnosed significantly (P<0.05). CONCLUSION Routine screening based on the identification of OME will facilitate the detection of a major amount of hearing impaired school-aged children.

Abstract
BACKGROUND Hearing loss is reported in about 50% of cases of chronic suppurative otitis media (CSOM). AIM To report the prevalence, type and severity of hearing loss in CSOM and identify risk factors. METHODS A prospective study of hearing loss in CSOM was undertaken in University College Hospital, Ibadan, two general hospitals and two primary health care centres, all in densely populated, semi-urban areas in south-west Nigeria. Controls were selected from school children, hospital workers' children and children whose parents were visiting the hospitals, all of whom claimed that there had been no episode of otitis media in the past. An oral questionnaire was administered to all, followed by audiometry and examination of the ear, nose and throat in study children. RESULTS There were 189 CSOM subjects and 100 controls aged between 4 and 150 months [mean (SD) 59.25 (44.55), 173 girls and 116 boys, M:F 1.5:1]. The prevalence of hearing loss in CSOM was 89/189 (47%) and was conductive in 73/89 (82%) and sensorineural (SHL) in 16/89 (18%). Of the subjects with hearing loss, 72% had had otitis media during the 1st year of life. Of the 89, 61 (69%) were of low social class, 13/37 (35%) were middle class and 15/63 (24%) upper class. The duration of CSOM ranged from 4 weeks to 12 years [mean (SD) 4 yrs (2.04)] and from 5 to 12 years in those with SHL [mean (SD) 9 yrs (6.21)]. There was significant correlation between socio-economic status and hearing loss (r=0.138, p=0.02) while no correlation was found with upper respiratory infection (r=0.054, p=0.36), age of onset (r=0.037, p=0.62) or frequency of attacks (r=-0.068, p=0.35). CONCLUSION About one fifth of patients with CSOM have SHL. Early diagnosis and management of CSOM is imperative to improve outcome. CSOM is strongly associated with low socio-economic status.

Abstract
The hearing profile amongst school learners in the Western Cape was investigated. The University of Cape Town's hearing-screening programme at 11 primary schools (n=1101) was audited and revealed a 13.8% referral rate amongst school-aged children. The possible effects of environmental noise on hearing-screening performance at 500Hz was investigated. When the hearing-screening results at 500Hz were excluded from the audit, the referral rate was reduced from 13.8% to 7.9%. The referral rate for hearing-screening failures amongst the learners in the sample was towards the high end of the range for developing countries (3.3-13.9%). More learners had unilateral than bilateral hearing failures while laterality, gender and geographical differences were minimal. This high referral rate suggests a strong need for hearing-screening of the school-aged population.

Abstract
The morbidity and mortality associated with otitis media is really a challenge for the health care systems. This study is a small attempt to look into the magnitude of this problem in the society, where in school going children in Yavatmal city were studied. A total of 4104 students were studied. It was found that the overall prevalence of chronic suppurative otitis media in Yavatmal city is 3%. The incidence of acute otitis media was found to be 1.3% Chronic suppurative otitis media was commoner in students belonging to low socioeconomic strata and its association with adenoid hypertrophy was statistically significant. The authors recommend that a few more such studies should be carried out in different parts of the country to collect vital data for the health care system managers.

Abstract
A statistical study was carried out on SNHL in CSOM. The study group consisted of 1,828 patients suffering from CSOM who underwent surgery at our centre from 1982 to 2001, out of these 510 cases with unilateral CSOM were selected for this study by a strict selection criteria so as to eliminate covariables such as exposure to acoustic trauma, head injury, previous ear surgery and hereditary causes. The healthy ear served as control. We determined the average SNHL in relation to the age of onset, duration of disease, examining it in relation to other eventual aural complications such as cholesteatoma, ossicular chain erosion und otorrhea.On the basis of data obtained we observed consistent co-relation between severity of SNHL and duration of the disease, presence of cholesteatoma, ossicular erosion, attic and subtotal perforations. These findings suggest that more severe middle ear disease may result in SNHL and thus early intervention in cases of chronic suppurative Otitis media is desired.

Abstract
The late detection of permanent congenital and early-onset hearing loss (PCEHL) often has severe effects on linguistic, speech, cognitive and educational development in affected children. Since newborn hearing screening (NHS) allows most PCEHL to be detected early enough for optimal intervention, the prospects of its introduction in the developing world are reviewed in this paper. It is observed that a simple generalisation on the feasibility of NHS for the developing countries seems inappropriate in view of the diversities in the health and socio-economic status of these countries and the recent favourable reports of universal newborn hearing screening from the region. NHS empowers parents to make timely choices that will allow their hearing impaired children to be given a good start in life and be fully integrated into the wider community. It also compels attention towards the development of essential hearing healthcare services, besides the specific documented benefits. Existing child-healthcare structures such as the expanded programme on immunisation (EPI), baby friendly hospital initiatives (BFHI) and integrated management of childhood illness (IMCI) provide opportunities for the introduction of some form of NHS in many of these countries where routine or systematic childhood hearing screening does not exist. Limited funding, manpower shortages, inadequate support services, low public awareness and the uncertainty regarding the commitment from healthcare practitioners may present some challenges but these are not insurmountable. Pilot studies are necessary in each country to provide empirical data that will guide healthcare providers who wish to introduce such a programme at any level of healthcare delivery.

Abstract
The aim of this study was to determine whether children in whom impacted cerumen had been removed were at greater risk of hearing impairment than those without a history of impacted cerumen. A retrospective study was conducted in 113 subjects and their pair-matched controls taken from a population of 359 randomly selected school entrants who received otoscopic, audiometric and tympanometric evaluations. It was found that children from whom impacted cerumen had been removed were more likely to have hearing loss (p = 0.0001), and of a more permanent nature (p = 0.002). They were also likely to have more otitis media with effusion (OME) (p = 0.045). Children with a history of impacted cerumen are therefore at greater risk of subsequent hearing problems and of a more permanent nature than those without, notwithstanding the removal of such impacted cerumen. The prevention of cerumen impaction should be of significant public health concern in the management of hearing impairment in children, especially where there is no routine and systematic screening for hearing disorders.

Abstract
The feasibility of training teachers of day care centres for children (balwadi teachers) to recognize and manage common ear problems was studied so that they could provide primary care for ear related morbidity in the community. A training module was designed, piloted on grass root level workers and used to train 19 balwadi teachers. Their knowledge, skills and technique of examination was assessed following training. Pathways for referral were established between the balwadis, secondary and tertiary hospitals. The knowledge score of the balwadi teachers increased from a mean of 28.4% to 86%; they scored an average of 75% in an assessment of their examination technique. Their sensitivity in identifying overall ear related morbidity was 75%, and 96% in identifying children with ear discharge, specifically. Age, education and experience did not affect the outcome of their training. While it may be premature to comment on the impact of the training, periodic supervision, close monitoring and review sessions would sharpen the skills of the balwadi teachers and improve their efficiency.

Abstract
OBJECTIVE To find out the prevalence and causes of hearing impairment among children of school-entry age, in rural areas of coastal south India. METHODS The study adopted the World Health Organization (WHO) guidelines viz., "The Prevalence of Ear and Hearing Disorders Protocol". A total of 855 children studying in the first year of school were examined using a Portable Pure Tone Audiometer and an Otoscope. Children with hearing impairment were re-examined to find out the type of hearing impairment. Mothers of all children were interviewed in their homes, in order to obtain details of socio-economic status, family history and history of consanguinity. RESULTS Hearing impairment was detected in 102 children (11.9%) and impacted wax was found to be the most common cause of hearing impairment (86.3%). On re-testing, it was predominantly conductive hearing impairment (81.6%) observed among 74 of these children. The prevalence of hearing impairment was significantly lower among children belonging to high socio-economic status (P=0.0036). CONCLUSIONS Hearing impairment and preventable ear diseases were found to be important health problems among children of school-entry age group in this region. Regular screening of children of school-entry age will ensure that children begin their school-life without this disability.

Abstract
OBJECTIVE The first epidemiological study carried out in Latin America to investigate the prevalence of otological disease and its impact in a representative random sample of the school children population. METHODS A cross sectional epidemiological survey to investigate the epidemiology of otitis in a representative random sample of 1119 children and adolescents from a total of 486166 elementary and high-school students, aged 6-18 years, regularly registered in one of the 521 public and private schools of the city of Belo Horizonte, in the state of Minas Gerais, southern Brazil. The interviews were conducted individually, in the school, by an otolaryngologist or a pediatrician. The interview included all of the personal data and also detailed questions regarding otological disorders and hearing. The otological examination was carried out with Mini-Heine otoscopes and the audiometric evaluation with the AudioScope 3 with 25dB intensity. The questionnaire and basic procedures for medical examination had been previously tested through a pilot test in two schools. RESULTS The prevalence of chronic otitis media was 0.94%. Impacted wax was found in 12.3% of the students. The prevalence of abnormalities (excluding wax) in the otoscopy examination was 10.5%. It was found that 8.3% of students had a past history of otitis and 7.7% had a past history of otorrhea. These two special groups presented statistically significant associations with chronic otitis media, hearing loss and otolaryngological surgeries (when compared with the other school children). Parents and school children seemed significantly able to identify a special group of children with past history of otitis during childhood.
