Abstract
OBJECTIVES To investigate the incidence and characteristics of adult otitis media with effusion (OME) before, during, and after the COVID-19 pandemic. METHODS A retrospective descriptive study was conducted. The incidence, age, sex, affected ear side, time of OME onset according to COVID-19 and days of improvement after conservative treatment were determined to assess the clinical features of adult OME in different periods of the COVID-19 pandemic. RESULTS The incidence of adult OME during these periods was 3.17%, 2.30%, 6.18%, and 3.68%, respectively. Unilateral ear involvement and male sex were more common. The onset of adult OME occurred 7.80 ± 3.97 days after COVID-19 diagnosis, and improvement was observed after 12.24 ± 5.08 days of conservative treatment. Patients in the post-pandemic period were older than those in the non-pandemic period. CONCLUSION The incidence of adult OME in China showed a tendency to decrease, recover, and decrease again following the COVID-19 outbreak. Pandemic prevention and control measures have had a certain impact on reducing the incidence, but the elderly are more prone to this disease.

Abstract
BACKGROUND Three infants with different risk factors, behavioral and physiologic audiometric histories, and diagnoses were fit with amplification between 3 and 8 months of age. Two of the three met criteria for cochlear implantation. PURPOSE This article aims to heighten awareness of the rare possibility of recovery from sensorineural hearing loss in infants with varying histories and emphasize the importance of a full diagnostic test battery in all infants diagnosed with sensorineural hearing loss every 3 months until objective and subjective thresholds are stable to ensure appropriate intervention. RESEARCH DESIGN Case reports. RESULTS All three infants demonstrated improvement or full recovery of hearing and cochlear function by approximately 12 months old. Their change in hearing was discovered due to frequent follow-up and/or caregiver report. One of these infants was tentatively scheduled to have cochlear implant surgery 2 months later. CONCLUSION Appropriate early intervention for infants with hearing loss is critical to ensure maximum accessibility to speech and language cues. The Federal Drug Administration approves cochlear implantation in infants as young as 12 months. When providing audiometric management of infants with sensorineural hearing loss, it is imperative to conduct a full diagnostic test battery every 3 months (including tympanometric, acoustic reflex, and otoacoustic emission measurement) until objective and subjective thresholds are stable. There was no apparent pattern of factors to predict that the infants highlighted in these cases would recover. Discussion among pediatric audiologists and otologists and comparison of data from clinics across the U.S. is needed to identify predictive patterns and determine appropriate, consistent monitoring of infants with sensorineural hearing loss.

Abstract
BACKGROUND Little is known about the academic performance of children with unilateral congenital aural atresia (CAA). OBJECTIVE of review: Our objective was to summarize what is known about the academic performance of children with hearing loss by unilateral congenital aural atresia, in order to provide pragmatic recommendations to clinicians who see children with this entity. TYPE OF REVIEW Systematic review. SEARCH STRATEGY We conducted a systematic search in PubMed Medline, EMBASE, and Cochrane Library combining the terms "atresia" and synonyms with "unilateral hearing loss" and synonyms. Date of the most recent search was 16 May 2018. EVALUATION METHOD Two independent authors identified studies, extracted data, and assessed risk of bias. This review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Observational studies on the academic achievements of patients of any age with unilateral conductive hearing loss of any level due to congenital aural atresia were included. We considered grade retention, special education, individualized education plans, and parental report of school performance as outcome measures for academic achievement. RESULTS Two studies reporting on academic performance of patients with unilateral CAA, which both had a significant risk of bias. One study (n = 140) showed a grade retention rate of 3.6% (n = 5) in total. 15.7% (n = 22) needed special education, and 36.4% (n = 51) used an individualized education program. The second study, reporting on 67 patients with unilateral CAA, showed that 29.9% (n = 20) of the patients received school intervention, and 25.4% (n = 17) had learning problems. CONCLUSION Current evidence regarding the effect of unilateral congenital aural atresia on academic performance is sparse, inconclusive and has a significant risk of bias. High quality observational studies assessing the effects of aural atresia on academic performance in these patients should be initiated.

Abstract
OBJECTIVE To investigate the epidemiology of cerumen impaction among children of municipal kindergartens in Wuhan. METHODS The ear canal of children of municipal kindergartens in Wuhan was examined using an electric otoscope by the same otologist in 2005, 2006 and 2012, with age, gender, ears and the nature of cerumen (dry cerumen or wet cerumen) recorded. A chi-square test was performed to investigate for significant differences between cerumen impaction rates and the recorded variables. RESULTS A total of 1,214, 1863 and 5205 children were examined in 2005, 2006 and 2012, and cerumen impaction prevalence rates for each year were 17.2%, 15.4% and 10%, respectively. Prevalence of cerumen impaction was significantly lower in 2012 than in 2005 or 2006. In 2005, dry cerumen impaction accounted for 22.2% of the total dry cerumen, while wet cerumen impaction only accounted for 5% of the total wet cerumen, showing a statistically significant difference. CONCLUSION The prevalence of cerumen impaction among children of kindergartens in Wuhan is higher than 10%, and children with dry cerumen are more prone to cerumen impaction. Annual otological examination of kindergarten children is recommended. And improved community ear health promotion activities should reduce the avoidable prevalence of cerumen impaction in pediatric population.

Abstract
CONTEXT Young people regularly expose themselves to leisure noise and are at risk for acquiring hearing damage. AIMS The objective of this study was to compare young adults' hearing status in relation to sociodemographic variables, leisure noise exposure and attitudes and beliefs towards noise. SETTINGS AND DESIGN A self-administered questionnaire regarding hearing, the amount of leisure noise exposure and attitudes towards noise and hearing protection as well as an audiological test battery were completed. Five hundred and seventeen subjects between 18 and 30 years were included. SUBJECT AND METHODS Hearing was evaluated using conventional audiometry, transient evoked and distortion product otoacoustic emissions. On the basis of their hearing status, participants were categorised into normal hearing, sub-clinical or clinical hearing loss. STATISTICAL ANALYSIS USED Independent samples t-tests, chi-square tests and multiple regression models were used to evaluate the relation between groups based on hearing status, sociodemographics, leisure noise and attitudes towards noise. RESULTS Age was significantly related to hearing status. Although, the subjects in this study frequently participated in leisure activities, no significant associations between leisure noise exposure and hearing status could be detected. No relation with subjects' attitudes or the use of hearing protection devices was found. CONCLUSIONS This study could not demonstrate clinically significant leisure noise-induced hearing damage, which may lead to more non-protective behaviour. However, the effects of leisure noise may become noticeable over a long-term use since age was found to be related with sub-clinical hearing loss. Longitudinal studies are needed to evaluate the long-term effects of noise exposure.

Abstract
Purpose The purpose of this study was to describe the auditory phenotype of a large cohort with Smith-Magenis syndrome (SMS), a rare disorder including physical anomalies, cognitive deficits, sleep disturbances, and a distinct behavioral phenotype. Method Hearing-related data were collected for 133 individuals with SMS aged 1-49 years. Audiogram data (97 participants) were used for cross-sectional and longitudinal analyses. Caregivers completed a sound sensitivity survey for 98 individuals with SMS and a control group of 24 unaffected siblings. Results Nearly 80% of participants with interpretable audiograms (n = 76) had hearing loss, which was typically slight to mild in degree. When hearing loss type could be determined (40 participants), sensorineural hearing loss (48.1%) occurred most often in participants aged 11-49 years. Conductive hearing loss (35.2%) was typically observed in children aged 1-10 years. A pattern of fluctuating and progressive hearing decline was documented. Hyperacusis was reported in 73.5% of participants with SMS compared with 12.5% of unaffected siblings. Conclusions This study offers the most comprehensive characterization of the auditory phenotype of SMS to date. The auditory profile in SMS is multifaceted and can include a previously unreported manifestation of hyperacusis. Routine audiologic surveillance is recommended as part of standard clinical care.

Abstract
PURPOSE A representative sample of the literature on minimal hearing loss (MHL) was reviewed to provide evidence of challenges faced by children with MHL and to establish the need for evidence-based options for early intervention. METHOD Research articles published from 1950 to 2013 were searched in the Medline database using the keywords minimal hearing loss, unilateral hearing loss, and mild hearing loss. References cited in retrieved articles were also reviewed. RESULTS In total, 69 articles contained relevant information about pediatric outcomes and/or intervention for unilateral hearing loss, 50 for mild hearing loss, and 6 for high-frequency hearing loss. Six challenges associated with MHL emerged, and 6 interventions were indicated. Evidence indicates that although some individuals may appear to have no observable speech-language or academic difficulties, others experience considerable difficulties. It also indicates that even though children with MHL may appear to catch up in some areas, difficulties in select domains continue into adulthood. CONCLUSIONS Evidence indicates significant risks associated with untreated MHL. Evidence also demonstrates the need for early intervention and identifies several appropriate intervention strategies; however, no single protocol is appropriate for all children. Therefore, families should be educated about the impact of MHL and about available interventions so that informed decisions can be made.

Abstract
OBJECTIVES This study investigated automatic assessment of vocal development in children with hearing loss compared with children who are typically developing, have language delays, and have autism spectrum disorder. Statistical models are examined for performance in a classification model and to predict age within the four groups of children. DESIGN The vocal analysis system analyzed 1913 whole-day, naturalistic acoustic recordings from 273 toddlers and preschoolers comprising children who were typically developing, hard of hearing, language delayed, or autistic. RESULTS Samples from children who were hard of hearing patterned more similarly to those of typically developing children than to the language delayed or autistic samples. The statistical models were able to classify children from the four groups examined and estimate developmental age based on automated vocal analysis. CONCLUSIONS This work shows a broad similarity between children with hearing loss and typically developing children, although children with hearing loss show some delay in their production of speech. Automatic acoustic analysis can now be used to quantitatively compare vocal development in children with and without speech-related disorders. The work may serve to better distinguish among various developmental disorders and ultimately contribute to improved intervention.

Abstract
OBJECTIVES A family history of permanent childhood hearing loss is considered a risk factor for pediatric hearing loss, although its validity has been sparsely examined. This study aimed to: (1) investigate the prevalence and yield of this risk factor for congenital and postnatal hearing losses, (2) define the audiometric characteristics of hearing loss in children with positive family histories, and (3) assess the nature of the familial relationships. METHOD A retrospective cohort study including all children born in Queensland, Australia between September 2004 and December 2011 who had completed Healthy Hearing's newborn hearing screen (n=380,895). RESULTS (1) Prevalence of the risk factor was 1.09% (4138/380,895). Prevalence of the risk factor in congenital cases was 7.29% and in postnatal cases was 36.84%. A low yield was identified for both congenital and postnatal groups (1.43% and 1.7%, respectively). (2) The degree of loss in congenital cases was highly varied, whereas the predominant degree in postnatal cases was mild. The most frequent type of loss for congenital cases was sensorineural, whereas for postnatal cases it was conductive. (3) Maternal or sibling relationships were most commonly reported for congenital losses, and maternal or paternal relationships for postnatal losses. CONCLUSIONS Children with a family history of pediatric hearing loss should have their hearing screened at birth and be monitored throughout early childhood. However, more efficient surveillance methods should be considered in view of the high prevalence with low yield.

Abstract
OBJECTIVES Individuals with disabilities are often reported to have a high prevalence of undetected hearing disorders/loss, but there is no standardized hearing test protocol for this population. The purposes of this study were (1) to examine the hearing status of students with special needs in Taiwan, and (2) to investigate the use of an on-site hearing test protocol that would adequately detect hearing problems in this population and reduce unnecessary referrals for off-site follow-up services. METHODS A total of 238 students enrolled in two schools for special education and one habilitation center participated in the study. Most students had intellectual disabilities and some also had additional syndromes or disorders. A hearing screening protocol including otoscopy, tympanometry, and distortion product otoacoustic emissions was administered to examine students' outer, middle, and inner ear functions, respectively. Pure tone tests were then administered as an on-site follow-up for those who failed or could not be tested using the screening protocol. RESULTS Only 32.4% of students passed. When administered alone, the referral rate of otoscopy, tympanometry, and otoacoustic emissions were 38.7%, 46.0%, and 48.5%, respectively. The integration of these subtests revealed 52.1% of students needed follow-up services, 11.8% could not be tested, 2.5% had documented hearing loss, and 1.3% needed to be monitored because of negative middle ear pressure. The inclusion of pure tone audiometry increased the passing rate by 9.9% and provided information on hearing sensitivity for an additional 8.6% of students. CONCLUSION Hearing assessments and regular hearing screening should be provided as an integral part of health care services for individuals with special needs because of high occurrences of excessive cerumen, middle ear dysfunction, and sensorineural hearing loss. The training of care-givers and teachers of students with special needs is encouraged so that they can help identify hearing problems and reduce the negative impact of hearing disorders and hearing loss. The screening protocol needs to include subtests that examine the status of different parts of their auditory system. The addition of pure tone audiometry as an on-site follow-up tool reduced the rate of off-site referrals and provided more information on hearing sensitivity.

Abstract
BACKGROUND Children today are exposed to cell phones early in life, and may be the most vulnerable if exposure is harmful to health. We investigated the association between cell phone use and hearing loss in children. METHODS The Danish National Birth Cohort (DNBC) enrolled pregnant women between 1996 and 2002. Detailed interviews were conducted during gestation, and when the children were 6 months, 18 months and 7 years of age. We used multivariable-adjusted logistic regression, marginal structural models (MSM) with inverse-probability weighting, and doubly robust estimation (DRE) to relate hearing loss at age 18 months to cell phone use at age 7 years, and to investigate cell phone use reported at age 7 in relation to hearing loss at age 7. RESULTS Our analyses included data from 52 680 children. We observed weak associations between cell phone use and hearing loss at age 7, with odds ratios and 95% confidence intervals from the traditional logistic regression, MSM and DRE models being 1.21 [95% confidence interval [CI] 0.99, 1.46], 1.23 [95% CI 1.01, 1.49] and 1.22 [95% CI 1.00, 1.49], respectively. CONCLUSIONS Our findings could have been affected by various biases and are not sufficient to conclude that cell phone exposures have an effect on hearing. This is the first large-scale epidemiologic study to investigate this potentially important association among children, and replication of these findings is needed.

Abstract
PURPOSE This tutorial provides framework and context for understanding the complex interaction of hearing measurement methodology and cohort social factors, as well as their relation to approaches to data interpretation and identification of minimal hearing loss (HL) in audiometric surveys. METHOD Pertinent archival studies were reviewed, and an original analysis on U.S. Centers for Disease Control and Prevention (CDC) audiometric survey data from children (ages 6-19) was performed. CONCLUSION The definition of an otologically normal individual, the pass-fail criterion representing the upper limit of the range of normal hearing, and the quality of the audiometry affect the percentage of persons who are falsely identified as having a minimal HL. An upper limit of normal hearing of 15 dB HL yields an unacceptably high false-positive rate, particularly when the more variable higher audiometric frequencies are examined. When air-conduction thresholds are assessed in isolation to estimate potential noise damage, the failure to exclude persons who have possible middle and external ear problems, including earwax, results in high false-positive rates. When these factors and other limitations are considered, audiograms from teens from a recent CDC survey do not show evidence consistent with widespread noise-induced HL. Suggestions are made to improve the effectiveness of pure-tone audiometry and the identification of minimal HL.

Abstract
We report pure-tone hearing threshold findings in 56 college students. All subjects reported normal hearing during telephone interviews, yet not all subjects had normal sensitivity as defined by well-accepted criteria. At one or more test frequencies (0.25-8 kHz), 7% of ears had thresholds ≥25 dB HL and 12% had thresholds ≥20 dB HL. The proportion of ears with abnormal findings decreased when three-frequency pure-tone-averages were used. Low-frequency PTA hearing loss was detected in 2.7% of ears and high-frequency PTA hearing loss was detected in 7.1% of ears; however, there was little evidence for 'notched' audiograms. There was a statistically reliable relationship in which personal music player use was correlated with decreased hearing status in male subjects. Routine screening and education regarding hearing loss risk factors are critical as college students do not always self-identify early changes in hearing. Large-scale systematic investigations of college students' hearing status appear to be warranted; the current sample size was not adequate to precisely measure potential contributions of different sound sources to the elevated thresholds measured in some subjects.

Liao WH, Lien CF, Young ST. The Hearing Scale Test for hearing screening of school-age children. Int J Pediatr Otorhinolaryngol 2010; 74:760-4.

Abstract
OBJECTIVES This study aimed to demonstrate a new modified hearing screening method that can rapidly screen hearing and provide stratified test values for each screened ear of children. METHODS The proposed Hearing Scale Test (HST) and pure-tone screening (PTS) were applied to 384 school-age children. PTS involved applying four test tones to each tested ear: 500 Hz at 25 dB, and 1000, 2000, 4000 Hz at 20 dB; and classifying the results as "pass" (normal hearing in the ear) or "fail" (possible hearing impairment). The HST employs ten stratified hearing scales from S(1) to S(10), with each hearing scale containing four test tones and where adjacent scales differ from each other by 5 B, ranging from 0 dB (S(1)) to 45 dB (S(10)). The four test tones of hearing scale S(5) are the same hearing criteria and the median reference standard of the stimulus level in the HST. Scales S(1)-S(5) on the HST are equivalent to a PTS "pass" result, while S(6)-S(10) and no response (NR) are equivalent to a PTS "fail" result. RESULTS The two screening methods produced comparable "pass" and "fail" results. In the HST, the "pass" results were further stratified as S(1) in 4 ears, S(2) in 52 ears, S(3) in 226 ears, S(4) in 272 ears, and S(5) in 169 ears, while the "fail" results were stratified as S(6) in 23 ears, S(7) in 12 ears, S(8) in 1 ear, S(9) in 2 ears, S(10) in 5 ears, and no response (NR) in 2 ears. The hearing screening results of the HST are interpreted as follows: scales S(1)-S(5) indicate normal hearing, scales S(6) and S(7) indicate possible hearing impairment, and scales S(8)-S(10) and NR indicate confirmed hearing impairment. CONCLUSIONS Conventional PTS only gives a pass/fail result for each screened ear, lacks hearing status assessment, and lacks stratified test values to be recorded for follow-up. In contrast, the HST has stratified hearing scales for each screened ear, which reflects the current hearing status and provides test values that can be recorded for follow-up.

Abstract
The optimal treatment for bilateral hearing loss continues to evolve as cochlear implant (CI) and hearing aid technologies advance, as does our understanding of the central auditory system. Ongoing discussions continue on the validity and feasibility of bilateral CI in terms of performance, justification of need, medical/surgical safety concerns, and economics. The purpose of this review article is to provide an update on the advantages and disadvantages of bilateral CI and to provide a discussion on timing (simultaneous vs. sequential), technology (bimodal vs. binaural) and feasibility. Binaural advantages are found in both adult and pediatric bilateral CI recipients, the greatest being the head shadow effect and improvements in localization and loudness summation. This theoretically offers an advantage over their unilateral implanted counterparts in terms of improved sound localization and enhanced speech perception under noisy conditions. Most investigators agree that bilateral stimulation during critical periods of development is paramount for optimizing auditory functioning in children. Currently, bilateral CI is widely accepted as a safe and effective means of bilateral auditory stimulation.

Abstract
Severe hearing loss among children has often been found to be associated with educational disadvantage and lower-than-average performance on cognitive tests, but less is known about the much more widespread milder levels of hearing loss. In a cohort of 22 162 young Danish men appearing before the draft board, about 75% had normal hearing at 20 dB, and about 20% had mild hearing loss not worse than 25 dB in both ears for all tones less than 3000 Hz, and not worse than an average of 45 dB in both ears for all tones above 2000 Hz. The remaining 5% had more severe hearing loss. The proportions who had continued school education after age 16 years among the three groups were 51%, 42% and 34% respectively and their mean IQs were 101, 98 and 94. The evidence suggests that even mild hearing loss is associated with distinct educational and cognitive disadvantage which itself may result from difficulties in following classroom teaching.

Air-conduction estimated from tympanometry (ACET): 2. The use of hearing level-ACET discrepancy (HAD) to determine appropriate use of bone-conduction tests in identifying permanent and mixed impairments. Int J Pediatr Otorhinolaryngol 2009; 73:43-55. [PMID: 18986713 DOI: 10.1016/j.ijporl.2008.09.023] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2008] [Revised: 09/05/2008] [Accepted: 09/09/2008] [Indexed: 11/22/2022]
Abstract
OBJECTIVE The caseload at secondary care in paediatric otology is largely otitis media with effusion (OME) and highly recurrent acute otitis media (RAOM). Few of these cases merit suspicion for hearing loss beyond the middle ear. The companion paper showed that the air conduction estimated from tympanometry (ACET) formula, derived on a very large clinical sample referred for ear or hearing problems and pre-assessed for a clinical trial, gives usable although only approximate estimates for hearing level (HL) on such a caseload. Tympanometry corresponds to a conductive loss (i.e. air-bone gap) so the HL-ACET discrepancy (HAD) should approximate the bone-conduction (BC) threshold. Clinical criteria might enable HAD to substitute for BC tests where those are infeasible, or to identify those most needing BC tests. METHOD ACET had been derived for the 4-frequency binaural average on 3085 cases with tympanometry and air-conduction HL available. On the 2701 of those with BC data at 1kHz, we re-calculated ACET for 1kHz only, and then explored the sensitivity/specificity trade of the discrepancy (HAD) in detecting clinically significant BC levels and the correlation between these measures. We further illustrated the generalization of the formula and cut-off on a small separate retrospective clinical sample. RESULTS Correlations were moderate in the clinically relevant region. There were five cases of BC> or =30dB in the database. At a HAD cut-off of +5dB, the sift would identify all (nominal 100% sensitivity). For marginal cases, two definitions were adopted (BC> or =25dB and > or =20dB; 9 and 23 cases, respectively). Sift sensitivity remained high (89% and 83%, respectively), and specificity was acceptable (75% for both definitions). CONCLUSIONS Given tympanometry and air-conduction HL, comparison of HAD with a recommended cut-off gives acceptable sensitivity and specificity for non-OME hearing problems. BC testing can be reserved for probable positive cases, provisionally only 25% of caseload. HAD could temporarily substitute for BC measurement in children too young to accept bone-conduction transducers in awake testing. Where a high proportion of the caseload is expected to have middle ear fluid, ACET and HAD together offer efficient possibilities for best use of available information.

Abstract
PURPOSE The purpose of the present study was to examine the effect of minimal hearing loss (HL) on children's ability to perform simultaneous tasks in quiet and in noise. METHOD Ten children with minimal HL and 11 children with normal hearing (NH) participated. Both groups ranged in age from 8 to 12 years. The children categorized common words (primary task) while completing dot-to-dot games (secondary task) in quiet as well as in noise presented at 0 dB and +6 dB signal-to-noise ratios (SNRs). It was hypothesized that the children's progression through the dot-to-dot games would slow as they encountered more difficult listening environments. This hypothesis was based on the theory that listeners have limited cognitive resources to allocate to any combination of tasks. RESULTS The dot rate of both groups decreased similarly in the multitasking conditions relative to baseline. However, no other differences between groups or listening conditions were revealed. Significantly poorer word categorization was observed for the children with minimal HL in noise. CONCLUSION These data suggest that children with minimal HL may be unable to respond to a difficult listening task by drawing resources from other tasks to compensate.

Abstract
OBJECTIVE Ninety percent of all newborns in the United States are now screened for hearing loss before they leave the hospital. Many hospitals use a 2-stage protocol for newborn hearing screening in which all infants are screened first with otoacoustic emissions (OAE). No additional testing is done with infants who pass the OAE, but infants who fail the OAE next are screened with automated auditory brainstem response (A-ABR). Infants who fail the A-ABR screening are referred for diagnostic testing to determine whether they have permanent hearing loss (PHL). Those who pass the A-ABR are considered at low risk for hearing loss and are not tested further. The objective of this multicenter study was to determine whether a substantial number of infants who fail the initial OAE and pass the A-ABR have PHL at approximately 9 months of age. METHODS Seven birthing centers with successful newborn hearing screening programs using a 2-stage OAE/A-ABR screening protocol participated. During the study period, 86634 infants were screened for hearing loss at these sites. Of those infants who failed the OAE but passed the A-ABR in at least 1 ear, 1524 were enrolled in the study. Data about prenatal, neonatal, and socioeconomic factors, plus hearing loss risk indicators, were collected for all enrolled infants. When the infants were an average of 9.7 months of age, diagnostic audiologic evaluations were done for 64% of the enrolled infants (1432 ears from 973 infants). RESULTS Twenty-one infants (30 ears) who had failed the OAE but passed the A-ABR during the newborn hearing screening were identified with permanent bilateral or unilateral hearing loss. Twenty-three (77%) of the ears had mild hearing loss (average of 1 kHz, 2 kHz, and 4 kHz < or =40-decibel hearing level). Nine (43%) infants had bilateral as opposed to unilateral loss, and 18 (86%) infants had sensorineural as opposed to permanent conductive hearing loss. CONCLUSIONS If all infants were screened for hearing loss using the 2-stage OAE/A-ABR newborn hearing screening protocol currently used in many hospitals, then approximately 23% of those with PHL at approximately 9 months of age would have passed the A-ABR. This happens in part because much of the A-ABR screening equipment in current use was designed to identify infants with moderate or greater hearing loss. Thus, program administrators should be certain that the screening program, equipment, and protocols are designed to identify the type of hearing loss targeted by their program. The results also show the need for continued surveillance of hearing status during childhood.

Abstract
Nongenetic as well as genetic etiologies must be explored in the child with identified hearing loss. Graduates of the neonatal intensive care unit are at increased risk for developing hearing loss due to hypoxia, hyperbilirubinemia, very low birth weight, and ototoxic medications. Although meningitis has decreased in frequency, it is still a risk factor for hearing loss. Cytomegalovirus remains the most common congenital infection and a relatively common etiology of hearing loss, which can be progressive. Preventable causes of hearing loss include those caused by head trauma, noise, and ototoxic medications. Identification of the etiology of hearing loss can facilitate the development of a treatment and management plan.

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
OBJECTIVES To discuss the diagnosis and management of children with fluctuating sensorineural hearing loss, especially focusing on those problems dealing with autoimmune inner ear disease. STUDY DESIGN A retrospective chart review of a large pediatric otolaryngology practice. A series of 40 children with progressive hearing losses was identified. Of that group, 22 children, aged 1.5 to 12.2 years at first audiogram, were considered to have fluctuating sensorineural hearing loss (FSNHL). Criteria for inclusion in the FSNHL group were threshold variations of 15 dB or more in at least one ear at two or more of the standard audiometric frequencies on at least 2 testing days. METHODS Charts were reviewed for age, sex, otologic history, laboratory evaluations, medical or surgical treatments, significant medical history, and family medical history. RESULTS Twenty-two children met the criteria for fluctuating sensorineural hearing loss. Of those with fluctuating hearing loss, 15 were idiopathic, 3 had positive lymphocyte transformation tests (LTT) suggestive of autoimmune inner ear disease (AIED), and 4 had fistula on middle ear exploration. Average fluctuation for all groups was 29.1 dB. Average duration of fluctuations was 4.95 years. CONCLUSIONS The majority of pediatric FSNHL cases (15 of 22) were idiopathic in nature. Of those FSNHL children with positive LTTs, only one was treated with steroid therapy. In the other patients with positive LTTs, parents or other physicians were often reluctant to treat, or the patient was lost to follow-up. Mean fluctuations varied substantially across all standard audiometric frequencies for all groups.

Abstract
Neonatal identification of congenital hearing impairment allows interventions during the first 3 years, the critical period for language and speech development. Two recently developed biophysical testing methods offer simple, accurate, and relatively inexpensive means to identify the one to three in 1,000 healthy newborns with hearing loss. Universal screening for auditory system integrity is advocated, because almost half of all newborns with hearing impairment have no risk factors associated with this impairment. Critics of universal screening cite the high rate of false positive tests (up to 7%), which increases program costs from follow-up and re-testing large numbers of infants to ensure identifying the few affected infants. As of early 2000, 24 states had introduced some type of auditory screening program, and the U.S. Congress had passed legislation with appropriations mandating state-based auditory screening for all newborns. Midwives practicing in states already mandating biophysical screening need to comply with their local requirements; those in other states may voluntarily incorporate new auditory test methods into practice.

Abstract
The effects of early onset, unilateral conductive hearing loss on tone-induced 2-deoxyglucose (2-DG) uptake in the auditory cortex of juvenile Mongolian gerbils (Meriones unguiculatus) were studied. Atresia of the left ear canal was induced at postnatal day 9 (P9) to achieve reversible auditory deprivation prior to onset of hearing (around P12). Atresia either persisted (ATR, n=4) or the canal was opened 15 min before the 2-DG experiments (RE, n=4) at P27. Control animals were either non-deprived (CON, n=4), or their left ears were plugged acutely (PAX, n=4). In PAX, 2-DG uptake in primary auditory cortex (AI) and anterior auditory field (AAF) was lower in right than in left AI and AAF. In contrast, in ATR and RE, uptake was significantly higher on the right side contralateral to the atresia. Hence, atresia during early development leads to plastic changes resulting in an interhemispheric imbalance of functional metabolism in favor of the auditory cortex contralateral to the manipulated ear. Distances between tone-induced 2-DG labeling in AI and AAF were increased in PAX, but smaller in ATR in the right compared to the left hemisphere, suggesting effects of atresia also on spatial relations in cortical tonotopic maps.
