Book excerpt: Infant hearing screening with the combination of otoacoustic emissions and automated auditory brainstem response test : Is it worth it?Introduction : The implementation of universal hearing screening could lead to the accurate and rapid diagnose of children with sensoneural hearing loss. The methods that are used most widely are otoacoustic emissions (OAEu2019s) and automated auditory brainstem response test (AABR) Methods and results : For a period of 1.5 year, 469 infants with or without risk factors had hearing screening with a protocol including medical history ,otoscopy ,tympanogram and both OAEs and AABR. According to our results the sensitivity of AABR was 97.54% and the specificity 87.5%. The OAEs had sensitivity 82.92% and specificity 100%.Conclusion : According to our results AABR are having higher sensitivity whereas OAEs have higher specificity .Consequently the combination of the two tests seem to be the most accurate for the earliest detection of sensoneural hearing loss.

This book was released on 2015 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past half a century, considerable effort has been dedicated to the development of universal newborn hearing screening (UNHS) programs across the United States. Newborn hearing screenings have progressed from subjective assessments performed only on at-risk neonates to highly sensitive objective methods of screening auditory sensitivity in nearly all newborns in the country. The Joint Committee on Infant Hearing (JCIH, 2007), National Institutes of Health (NIH, 1993) and the American Speech-Language-Hearing Association (ASHA, 2004) all support the use of either otoacoustic emission (OAE) or automated auditory brainstem response (ABR) for UNHS. Because OAE testing only assesses cochlear function, ABR testing remains the gold standard for evaluating the functioning of the peripheral and central auditory system (i.e., to the level of the brainstem). Historically, ABRs have been evoked using a broadband click stimulus or tone burst stimuli. The click stimulus has been advocated for both neuro-diagnostic and newborn hearing screening applications. Recently, a chirp stimulus was developed to maximize the temporal synchronization of the responses from the underlying neural components. Researchers have shown that this increased synchrony produces larger amplitude ABRs in both adults and infants, even at low intensity levels, potentially reduces test time, and is comparable to the "stacked" ABR. To date, however, few researchers have investigated the effects of manipulating multiple stimulus parameters in both adult and neonate participants. The purpose of this dissertation was to collect normative data based on a multitude of stimulus manipulations, using both air and bone-conducted CE-Chirp and octave band stimuli in newborns and young adults. Additionally, ABR responses to air and bone-conducted chirp stimuli were compared to traditional ABRs to click and tonal stimuli in newborns. Latency and amplitude of ABR waveform components, primarily wave V, were examined. In Experiment 1, it was shown that ABRs to CE-Chirp stimuli are signifcantly (p

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective - Early diagnosis and treatment of congenital and acquired hearing impairment in newborns is a key element for optimal speech development. The automated auditory brainstem response (AABR) method is considered to be superior to the otoacoustic emission (OAE) method, as it detects hearing deficit not only at the level of ear but also of neural origin. Recent recommendations suggest implementation of AABR to newborn hearing screening, to identify the group of newborns at higher risk of hearing impairment. Aim u2013 The aim of the study was to analyze the effectiveness of OAE and AABR used as screening tools for hearing impairment among infants. Material and methods u2013 The group of 350 infants (250 u2013 with risk factors of hearing deficit; 100 u2013 control group) was examined by means of both OAE and AABR before discharge from the hospital after birth. The risk factors of hearing deficit were recorded. Infants who failed the screening test and/or had risk factors were referred for further audiological evaluation.Results u2013 The results of OAE were positive in 4 newborns bilaterally and in 1 unilaterally. In 2 infants OAE was not performed due to anatomical defects or respiratory support. The results of AABR were positive in 7 newborns bilaterally and in 13 unilaterally. One newborn in whom both OAE and AABR were positive was finally diagnosed with bilateral sensorineural profound hearing deficit > 90 dB; the identified risk factor was congenital cytomegalovirus infection. Five newborns of the study group and one of the control group in whom OAE was negative and AABR was positive either unilaterally or bilaterally, finally have not been diagnosed with hearing deficit (false positive screening). Other infants in whom AABR was positive do not have the final diagnosis of hearing status yet. All newborns of the study group had at least one risk factor of hearing deficit u2013 the most frequent were treatment in the intensive care unit (90%), mechanical ventilation (83.3%), and ototoxic treatment (75.1%). One newborn with negative results of both OAE and AABR and with risk factors of hearing deficit (prematurity, very low birth weight, ototoxic treatment, treatment in NICU and mechanical ventilation) was diagnosed with moderate hearing deficit (30 dB and 50 dB) at the second level of screening program (false negative screening). AABR exam was assessed by the staff as more difficult and time consuming to perform (mean time of the exam 7.4 min; SD 7.19) when compared to OAE.Conclusions - The AABR method, recommended as gold standard for hearing screening in premature babies, is very useful in early diagnosis of hearing impairment. It allows for early identification of infants with hearing deficit as it examines the entire auditory pathway. However, it seems to be more difficult to perform when compared to OAE.

This book was released on 2022-12-06 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 'Fast Facts: Early Hearing' Detection and Intervention an international team of contributors brings together the evidence that supports the effectiveness of universal newborn hearing screening (UNHS) and early hearing detection and intervention services (EHDI). As well as considering elements essential to successful UNHS/EHDI programs, including screening technologies, resources, data management and family-centered early intervention services, the team discusses the resources needed to deliver such programs as well as the performance of screening programs globally. The aim is to provide a comprehensive compendium of information to make the case for greater recognition of the importance of UNHS/EHDI and so improve the life chances of children who are diagnosed as deaf or hard of hearing. Table of Contents: • Newborn hearing screening and EHDI • Rationale for UNHS/EHDI programs • Prevalence of newborn hearing loss and performance of screening programs • Global status of newborn and infant hearing screening • Genetic and CMV testing • Medical evaluation and management of permanent childhood hearing loss • Middle ear effusion and other barriers to timely diagnosis • Data management systems for newborn hearing screening programs • Establishing UNHS/EHDI programs • Pediatric diagnostic audiology • Amplification device fitting • Family-centered early intervention • Unilateral hearing loss and auditory neuropathy spectrum disorder

Book excerpt: "Introduction: Current newborn hearing screening include testing with otoacoustic emission and automated auditory brainstem response. Unfortunately, both tests are affected by the presence of material in the ear canal and middle ear such as vernix, meconium and amniotic fluid. The primary objective of this study was to perform wideband measurements and otoscopy on newborns in order to determine whether occlusion of the ear canal affects the wideband measurements. A secondary objective was to compare the wideband measurements obtained after birth to those taken at 14 to 28 days later. A third objective was to obtain additional wideband normative data in newborns. Materials and Methods: Newborns from a well-baby nursery were enrolled. Wideband measurements under both ambient and pressurized conditions and otoscopy were done immediately after the hearing screening and between 14 and 28 days later. Occlusion of the ear canal as seen on otoscopy was described on a scale of 0 to 100% in increments of 10.Results: A total of 156 babies were enrolled. On the first measurement, a statistically significant difference in reflectance was found between 0-70% and 80-100% occlusion groups and between 6 groups of frequencies between 250 Hz and 8 kHz. There was no significant difference in reflectance between the right and the left ears. A comparison of reflectance under pressurised conditions between the first and second measurements has shown a higher reflectance at the negative pressure region during the first few days of life. Conclusion: Significant increase in reflectance occurs when 70% to 80% of the ear-canal diameter is occluded. A trend of higher reflectance appears to be present when the canal is pressurized to negative values. A comparison of reflectance between the present study and previous studies is given." --

Book Synopsis Universal Newborn Hearing Screening: Systematic Review to Update the 2001 U. S. Preventive Services Task Force Recommendation by : U. S. Department of Health and Human Services
Download or read book Universal Newborn Hearing Screening: Systematic Review to Update the 2001 U. S. Preventive Services Task Force Recommendation written by U. S. Department of Health and Human Services and published by Createspace Independent Pub. This book was released on 2013-06-18 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This systematic evidence review updates a prior review for the U.S. Preventive Services Task Force (USPSTF) on universal newborn hearing screening (UNHS) to detect moderate to severe permanent, bilateral congenital hearing loss (PCHL). In 2001, based on results of a prior systematic evidence review, the USPSTF concluded that the evidence was insufficient to recommend for or against routine screening of newborns for PCHL during the postpartum hospitalization (I Recommendation). The USPSTF provided additional specific conclusions about the evidence. They determined that methods of screening using otoacoustic emissions (OAEs) and auditory brainstem response (ABR) are highly accurate for identifying PCHL in newborns, and UNHS leads to earlier identification and treatment of infants with PCHL. They found that evidence was inconclusive regarding whether earlier treatment resulting from newborn screening leads to clinically important improvement in speech and language skills at age 3 years and beyond because existing studies had design limitations. The USPSTF considered that earlier identification and intervention may improve the quality of life during the first year of life, and prevent regret by the family over delayed diagnosis of PCHL, but limited data addressing these benefits existed. They were not able to determine whether potential benefits outweighed the potential harms of false-positive tests. This update focuses on critical evidence gaps that were unresolved at the time of the 2001 recommendation, and utilizes the format and methods of the prior systematic evidence review. The Joint Committee on Infant Hearing (JNIH), comprised of representatives from audiology, otolaryngology, pediatrics, education, and state speech and hearing programs, provides position statements and establishes practice standards for early identification, intervention, and follow-up care for infants and young children with hearing loss. According to the JCIH, hearing screening should identify infants at risk for specifically defined hearing loss that interferes with development. The targeted hearing loss for UNHS programs is permanent sensory or conductive hearing loss averaging 30 to 40 decibels (dB) or more in the frequency region important for speech recognition (approximately 500 through 4000 Hertz [Hz]). The focus of UNHS is on congenital as opposed to acquired or progressive hearing loss that may not be detected in the newborn period. The term “hearing impairment” is commonly used outside the U.S. instead of “hearing loss.” This systematic review updates the evidence from the prior 2001 USPSTF review for the following key questions: 1. Among infants identified by UNHS who would not be identified by targeted screening, does initiating treatment prior to age 6 months improve language and communication outcomes? 2. Compared with targeted screening, does UNHS increase the chance that treatment will be initiated by age 6 months for average risk infants? For high risk infants? 3. What are the adverse effects of UNHS and early treatment?
