Background/Aim. Prevention of the consequences of hearing loss can be accomplished by early hearing screening of the cochlear function in newborus, but also with continuous hearing screening in the early childhood. The aim of this study was to investigate the reliability and feasibility of otoacoustic emissions (OAE) in hearing screening in children, evaluate the frequency and type of hearing loss and determine etiological factors of these losses. Methods. In the study, 133 children, aged 2 to 7.5 years, were tested on both ears with transient evoked otoacoustic emissions (TEOAE) and distortionproduct otoacoustic emissions (DPOAE). Before screening tests all children had undergone otoscopic examination. If children had not passed either or both hearing screening tests and/or abnormal otoscopic findings in at least one ear, audiological evaluation was scheduled to confirm or exclude hearing loss. Results. Eighty-five percent of children passed the hearing and otoscopic screening bilaterally. For additional audiologic tests 15% of children were referred. Agreement between otoscopic examination and screening tests was very good (agreement for TEOAE 95%, for DPOAE 93%). The results showed that normal tympanograms were very likely to be associated with normal screening tests. Sensitivity of TEOAE test was 94.12%, specificity 78.95%, while DPOAE sensitivity was 87.50% and specificity 75%. Hearing loss was found in 6.76% of the cases, conductive in 6.01% and sensorineural in 0.75%. Conductive hearing loss was a consequence of chronic otitis media with effusion in 25% of the cases, and a consequence of adhesive process in the middle ear in 8.33% of cases. Sensorineural hearing loss was a consequence of using ototoxic medications. Conclusion. TEOAE and/or DPOAE tests are reliable, noninvasive, and feasible methods for hearing screening in childhood.

AbstractA retrospective review of 168 consecutive children with congenital or early-onset bilateral hearing impairment (>25 dB, 0.5–4 kHz, in the better hearing ear) was conducted. Only 39 per cent of the hearingimpaired children were diagnosed within the first two years of life. The age at diagnosis was related to the severity of hearing loss with profound (>95 dB) hearing losses being detected earlier than the other degrees. However, 37 per cent of children with severe to profound (>70 dB) hearing loss were still not diagnosed until after two years of age. Children with severe to profound hearing loss and with known risk factors were diagnosed earlier than children with the same hearing status but with no known risk factors. It was concluded that the behavioural hearing screening tests used in our well-baby clinics are insufficient and, therefore, more reliable methods, preferably evoked otoacoustic emissions, should be used for universal hearing screening of infants and young children in spite of the great cost.

Objective: To evaluate cochlear functioning in patients (18 - 45 years old) with varying stages of chronic kidney disease (CKD). Using purposive sampling, 50 participants, 10 in each of the 5 stages of CKD, were selected and underwent pure tone audiometric testing and distortion product otoacoustic emissions (DPOAEs).Results: Significant differences (p<0.05) were found between pure tone audiometry and DPOAEs in detecting early cochlear dysfunction in the high-frequency range in stages 3 (6 000/5 000 Hz; p=0.00), 4 (6 000/5 000 Hz; p<0.03) and 5 (4 000/3 333 Hz; p<0.01, 8 000/6 667 Hz:p<0.05) with DPOAEs being more sensitive in identifying early cochlear dysfunction. Patients in stages 1 and 2 presented with normal puretone thresholds and DPOAEs, suggesting that cochlear functioning in these patients was normal. Early cochlear dysfunction, thereby indicating a subclinical hearing loss, was identified in stages 3, 4 and 5 by DPOAE testing. In addition, blood test results, drug intake and concomitant conditions were recorded and analysed which suggested a relationship between reduced cochlear functioning and increased electrolyte levels, treatment regimens and concomitant conditions.Conclusion: Participants in the later stages of CKD presented with early cochlear dysfunction, presenting with subclinical hearing loss. It was postulated that this subclinical hearing loss resulted from a combination of electrolytic, urea and creatinine imbalances, together with concomitant medical conditions and ototoxic drug intake. It was concluded that audiological monitoring be included in the management of patients with CKD and that DPOAEs be introduced as part of the test battery to monitor cochlear function in patients with varying degrees of CKD.

Introduction  The present study was devised to estimate the prevalence of neonatal hearing loss and document the importance of using DPOAE as a screening tool for identifying hearing loss in newborns. Materials and Methods This hospital based descriptive study was conducted from August 2018 to August 2019. A total of 928 newborn babies were included in the study. These newborn babies were subjected to hearing screening by distortion product otoacoustic emissions (DPOAE) at 24-72 hrs after birth. For pass cases, no further testing was done. For refer cases, repeat testing with DPOAE was done within 15-30 days. Newborns with refer result on repeat DPOAE testing were subjected to Brainstem evoked response audiometry (BERA) within 3 months to confirm hearing loss. Results Nine hundred and twenty eight newborn babies were screened by DPOAE. 851 newborns passed the first DPOAE hearing screening and 77 newborns gave refer result. 21 newborns were lost to follow-up. 56 newborns underwent repeat DPOAE testing and 5 newborns were referred for BERA. Amongst the 5 newborns who underwent BERA testing, one newborn was diagnosed with bilateral profound hearing loss. Hence, the prevalence of hearing loss of 1.08 per thousand newborn babies was estimated in this study. Conclusion Hearing screening of newborns using DPOAE followed by BERA in refer cases to confirm hearing loss is useful for early detection followed by timely intervention and rehabilitation.

ABSTRACT Purpose: to survey the national and international literature on the impacts of the coronavirus infection on the auditory system. Methods: an integrative review with search in the BIREME, PubMed, Scopus, and Web of Sciences databases. Inclusion criteria: articles in Portuguese and English whose subject was the coronavirus infection and its effects on the auditory system. Exclusion criteria: information from books and/or chapters, letters to editors, review articles, experience reports. The search strategy was based on the following combined descriptors, respectively in Portuguese and English: “Infecções por coronavírus”, “Audição”, “Perda auditiva”, “Coronavirus infections”, “Hearing”, “Hearing Loss”. Results: out of 43 articles found, two approached the issue. The first study assessed 20 patients that tested positive for COVID-19, though asymptomatic, who underwent pure-tone threshold audiometry and otoacoustic emissions. A significant increase in the auditory thresholds at high frequencies and a smaller response amplitude in the transient evoked otoacoustic emissions of those who tested positive for COVID-19 were observed when compared to that of controls. The second study reported the case of an asymptomatic 35-year-old COVID-19 female patient, who complained of otalgia and tinnitus, after being contaminated. The pure-tone threshold audiometry and tympanometry indicated mild unilateral (right ear) conductive hearing loss, with a type B tympanometric curve on that side. Conclusion: the studies included in this review showed different consequences of COVID-19 on hearing, with possible impairments on the sensory and mechanical structures of the auditory system. The knowledge of COVID-19 is limited, and further studies on its real impact on the auditory system are necessary.

Clinical Factors

Background: Hearing loss is an important disorder affecting newborns admitted to NICU. A national hearing screening program using otoacoustic emission testing is an essential tool to identify hearing loss early in neonates enabling early intervention to avoid further challenges of pediatric deafness. On the other hand, a delay of the auditory pathway maturation in preterm babies compared to term newborns has already been suggested in the literature. Taking this information into account, in this paper, we aim to identify the best time to perform NICU infant hearing screening tests. Objectives: We aim to study the clinical factors and neonatal morbidities that may affect neonatal hearing screening results using otoacoustic emission test, in order to decrease the false positive test results that increase parental anxiety and increase the need for subsequent investigations. Methods: This is a prospective cross-sectional study that included 204 infants who were admitted to a tertiary referral hospital NICU unit between September 2017 and May 2018. Both transient evoked otoacoustic emissions (TEOAE) and distortion product otoacoustic emission (DPOAE) screening tests were performed in order to screen hearing loss. Results: Our study included 204 infants, 52.9% of which were males and 47.1% females. There were correlations between both hyperbilirubinemia and ventilation ≥5 days and the failure rate of the first OAE test results among NICU infants where the P-values were (p=0.0133) and (p=0.0456) respectively. Moreover, 165 babies (80.9%) passed the first OAE with a mean birth weight of 2759 gram and mean maternal age of 30.6 years, while 39 babies (19.1%) failed the test with a mean birth weight of 2436 gram and mean maternal age of 32 years. There was no statistically significant relation between both maternal age and birth weight with failure of the first screening test. Conclusion: Our study suggests a higher failure rate of the first OAE in NICU infants who had hyperbilirubinemia or ventilation ≥5 days. Therefore, our recommendation is to postpone the first phase of hearing screening for those infants until the first scheduled vaccine appointment to achieve high compliance to attendance and decrease distress to the family that can be associated with false-negative results of the test.

AbstractOtitis media with effusion (OME) is a common cause of vestibular disturbances in children. However, young children often lack the language to express their symptoms, and it is uncommon to screen children for vestibular impairments.The purpose of this study was to develop a screening protocol for children presenting with OME to determine if diagnostic vestibular testing is necessary.Children with normal hearing (NH), sensorineural hearing loss (SNHL), and conductive hearing loss (CHL) due to OME participated in a vestibular screening.There were 30 participants, ages four to eight years, ranging from 48 to 101 months included in the study: 10 with NH, 11 with CHL due to OME, and 9 with SNHL.The vestibular screening consists of patient and parent questionnaires and a functional evaluation. The tests examined coordination, balance, oculomotor function, and nystagmus.Those with CHL were significantly more likely to display abnormal smoothness of pursuit, as measured with observations for rapid tracking, absence of or delayed saccades, and overshoot, than those with NH or SNHL (p = 0.012). Parents of children with CHL due to OME were more likely to report their child experiencing middle ear pressure than the parents of children with NH or SNHL (p = 0.010). In addition, children with CHL were less likely to report hearing loss than those with NH or SNHL. Parent and patient report were not found to be reliable indicators of vestibular disturbances.This pilot study suggests that children with CHL due to OME present with more oculomotor abnormalities than their peers with NH. Further research is necessary to determine validity and reliability of the findings for this present study.
