Abstract
BACKGROUND In recent years, neonatal hearing screening (NHS) has gained rapid traction in both developed and developing nations. However, the efficacy of these efforts depends on comprehensive standardization across all screening facets. This study aimed to assess the status and quality of NHS by investigating the knowledge, attitudes, beliefs, and practices of hearing screening practitioners regarding NHS. METHODS A cross-sectional survey was conducted, and an online questionnaire based on the knowledge-attitude/belief (A/B)-practice model was distributed to all NHS practitioners in Luzhou, western China. Valid questionnaires were examined and uniformly graded. RESULTS A total of 63 valid questionnaires were collected. The practitioners were mainly female (96.83%), with nursing backgrounds (63.49%), and undergraduate degrees (66.67%). Most had ≤5 years of experience (74.60%) and had junior/intermediate titles (93.65%). The NHS within the Luzhou area started in 2006 with provincial institutions, expanding to 42 institutions by 2022. Statistically significant correlations were observed between the A/B score and the conducting years of each NHS institution (p < .05) as well as between the Knowledge (K) and Practice (P) scores (p < .01). No significant correlation was found between the K score, P score, A/B score, and working years of practitioners (p > .05), or in the total score of NHS institutions at different levels or in different counties by one-way ANOVA (p > .05). CONCLUSIONS It has been 17 years since the first medical institution in Luzhou launched NHS, and the overall performance of practitioners from different institutions has been consistent in terms of their knowledge, attitudes, or level of practice. However, there is room for further improvement in both the professional development of individuals and aspects related to work, such as health education and long-term follow-up.

Abstract
Universal hearing screening offers unique possibilities for detection of congenital deafness as a consequence of congenital cytomegalovirus (CMVc) infection, so its selective study in the case of a failed test could be a non-negligible screening opportunity while other guidelines covering the possibility of universal screening are adopted. The aim of this study is to analyse the possibility of selective screening for CMVc after an altered hearing test in a regional hospital. During the period studied, the results obtained were unsatisfactory, especially in children born outside the hospital of residence, showing an excessive delay in hearing screening in many cases and in the few cases where CMVc screening could be performed, only 30% had the test ordered in a timely manner. The reasons for this are varied and the solution is to include selective screening for CMVc in the hearing screening programme. This implies shortening the timing of the hearing screening protocol to allow CMVc testing in saliva or urine (preferably) before 21 days of age and providing screening programmes with the necessary staff and time to perform it properly.

Abstract
The effect of hypoxia on the functioning of the outer hair cells of the cochlea, which are responsible for the response to otoemissions used in neonatal hearing screening, is well known. The aim of this study is to determine the influence of mild to moderate variations in umbilical cord pH at birth on the outcome of hearing screening with otoemissions in healthy newborns without hearing risk factors. The sample is composed of 4536 healthy infants. The results show no significant differences in the hearing screening outcome between the asphyctic (<7.20) and normal pH group. Nor is a figure below 7.20 detected in the sample that is related to an alteration in the screening. When broken down into subgroups with known factors of variation in the screening result, such as gender or lactation, no significant differences in response were detected. Apgar ≤7 is significantly related to pH<7.20. In conclusion, mild-moderate asphyxia associated with delivery of healthy newborns, without auditory risk factors, does not alter the outcome of otoemission screening.

Abstract
Congenital hearing loss is hearing loss present in a child at birth or soon after birth. It is a debilitating condition with the potential for lifelong disability. It is thought to be multifactorial in aetiology with both genetic (autosomal and X-linked) and acquired causes (such as maternal infections, drug intake, trauma). Gestational Diabetes Mellitus (GDM) is a relatively common condition found in pregnant females but is a rather understudied risk factor in terms of congenital hearing loss. GDM is easily treatable which makes the hearing loss due to it easily preventable. (1) Determine correlation between Gestational Diabetes Mellitus and congenital hearing loss in neonates. (2) Calculate the prevalence of Gestational Diabetes Mellitus related congenital hearing loss. A two-step screening process was used for hearing evaluation of neonates with normal mothers (non-exposed) and neonates with mothers suffering from GDM (exposed) through Otoacoustic emission (OAE) and Brainstem Evoked Response Audiometry (BERA). (1) The difference of neonates diagnosed with hearing impairment in exposed and non-exposed group was statistically significant with a p-value of 0.024. OR 2.1538 95% CI 0.6120-7.5796, p < 0.05. (2) Prevalence of hearing loss in neonates of GDM mothers: 13.3%. Through rigorous exclusion of the already known risk factors for congenital hearing loss, Gestational Diabetes Mellitus has been isolated as an independent risk factor for neonatal hearing impairment. We hope to identify additional cases of congenital hearing loss early leading to a decrease in disease burden.

Abstract
Hearing loss has long been associated with congenital hypothyroidism and, if not noticed and treated early, may result in delayed language acquisition and difficulties in comprehension. In light of the implications of congenital hypothyroidism and its associated hearing loss, we decided to conduct this study. The aim of this study was to identify the prevalence of hearing loss in congenital hypothyroidism and its relation to the severity of the disease and age of initiation of treatment. This study was conducted from July 2016 to June 2021 at a tertiary care hospital in Bhopal. The hearing status of congenital hypothyroid children and matched controls was assessed by pure tone audiometry or free field audiometry and, in selected cases, with brainstem evoked response audiometry. Eight children (25%) with congenital hypothyroidism had hearing loss, compared to one (3.12%) in the control group (p < 0.05). No statistically significant difference has been found in the gender, mean age of diagnosis, mean age of initiation of levothyroxine treatment, mean screening FT4 levels, and mean screening TSH levels between congenital hypothyroid children with and without hearing loss. Due to the high prevalence of hearing loss in congenital hypothyroidism and its impact on language and cognitive development, it is critical to create awareness among healthcare professionals that children diagnosed with congenital hypothyroidism must undergo audiological evaluation at the time of diagnosis and periodically thereafter. Alternatively, children with unexplained hearing loss must be screened for congenital hypothyroidism.

Abstract
OBJECTIVE To evaluate the impact of the Universal Neonatal Hearing Screening (UNHS) on the age at diagnosis, beginning of treatment, and first cochlear implant surgery. METHODS A retrospective cohort study with children up to 12 years old with bilateral hearing loss were divided into two groups: patients who underwent UNHS and the ones who didn't. The groups were compared according to their age at the beginning of the evaluation at a specialized center, at the beginning of the intervention, and, for the ones who had indication, at the cochlear implant surgery. The group who underwent UNHS was divided between the ones who passed the screening test and the ones who didn't. They were compared according to their ages at the same moments as the first two groups. RESULTS 135 patients were included. The median age at the first appointment in a specialized center was 1.42 (0.50 and 2.50) years, at the beginning of treatment 2.00 (1.00 and 3.52) years, and the cochlear implant surgery 2.83 (1.83 and 4.66) years. Children who underwent UNHS were younger than those who didn't, at the three evaluated moments (p < 0.001). In a subanalysis, children who passed the UNHS but were later diagnosed with hearing loss reached the first appointment with a specialist and started treatment older than those who failed the tests. CONCLUSION Performing UNHS interfered with the timing of deafness diagnosis and treatment. However, children who passed the screening but were later diagnosed with hearing loss were the category with the most important delay.

Abstract
PURPOSE In 2015 a new regulation and guidelines for the universal newborn hearing screening by AABR measurement have been implemented in Hungary. The aim of our study was to analyse (1) the past 5 years of data from our diagnostic centre about the incidence and types of congenital hearing losses, and (2) the first experiences with the National Newborn Hearing Screening Registry, started in 2019, and (3) the influence of the screening on the pediatric cochlear implant program. METHODS 1269 children referred to our diagnostic centre between 2017 and 2021 were investigated. A third AABR measurement and full audiological evaluation were performed. Furthermore, one-year period data of the screening registry, and the number of implanted children at or under the age of 3 were analysed using the national databases. RESULTS Altogether 276 newborns (22% of the referred cases after the two-stage screening) had hearing loss, 134 (49%) out of them was conductive origin, almost twice frequent in male as in female. Permanent sensorineural hearing impairment was found in 142 (51%), 58 (40%) of them had bilateral, severe to profound hearing loss, occurring more frequently in male as in female. The national digital registration of the screening data within 12 months concerned 68%. The number of early cochlear implantation in one year increased from 1 to 23 children in the past 15 years. CONCLUSION A third AABR after the two-stage screening increased the efficiency and filtered the 78% false-positive cases. The audiological diagnostics verified and typed the hearing losses ensuring the early intervention.

Abstract
BACKGROUND Very preterm infants are at a greater risk of developing neurodevelopmental impairments such as neuro-motor delays, vision and hearing deficits (Roze and Breart, 2004; Saigal and Doyle, 2008) [1,2]. The hearing difficulties in preterm infants vary depending on the co-morbid conditions. However, prematurity itself is considered as a risk factor that influence the functioning of auditory system. AIM The current study aims to compare the DPOAEs in very preterm infants and term infants at 1 month, 3 months and 6 months of age (corrected age in preterm infants). METHOD DPOAEs were recorded in 72 very preterm infants and 30 term infants at 1 month, 3 months and 6 months of age. All these infants had obtained 'pass' results in newborn hearing screening using ABR. DPOAE f2 test frequency was measured at six frequencies (1500 Hz, 2000 Hz, 3000 Hz, 4500 Hz, 6000 Hz and 8000 Hz) with primary tone stimulus intensity L1 equal to 65 dBSPL and L2 equal to 55 dBSPL with primary tone f2/f1 frequency ratio of 1.2. Otoscopic examination and tympanometry was performed prior to DPOAE testing, to ascertain normal middle ear status. RESULTS DPOAE amplitude did not change significantly between two groups from 1 month till 6 months of age (p > 0.05). DPOAE amplitude and noise floor in very preterm infants were not different from term infants and DPOAE amplitude did not vary significantly across f2 frequencies at various time periods. CONCLUSION The current study findings provided evidence that prematurity did not constitute as a factor to influence the results of DPOAE in very preterm infants who passed newborn hearing screening test. Any significant reduction in DPOAE amplitude or absence of DPOAE in very preterm infants has to be considered and monitored effectively, as it may not reflect a developmental process of cochlear function; instead it could indicate the presence of inner ear or middle ear pathology.

Abstract
INTRODUCTION Recently, Interacoustics presented a new otoacoustic emission protocol where the probe pressurizes the ear cavity, thus eliminates the risk of non-assessment (REFER outcome) due to a negative middle ear pressure. This study evaluated the characteristics and the performance of this new protocol on a newborn well-baby population. METHODS One hundred sixty-three newborns (age 2.7 ± 1.1 days) for a total of 294 ears were assessed randomly. Transiently evoked otoacoustic responses were acquired by the Titan device (Interacoustics), using the default and a pressurized TEOAE protocol. The data were analyzed in terms of signal to noise ratios (S/Ns) at 5 frequencies, namely, 0.87, 1.94, 2.96, 3.97, and 4.97 kHz. To assess any possible gestational age (GE) effects on the TEOAE variables, the responses were subdivided in 4 different age subgroups. RESULTS There were no significant differences between the left and right ear TEOAE responses, for age (in days), GE (in weeks), weight (in grams), and S/N at all 5 frequencies. Considering the pooled 294 ears, paired t tests between the default and the pressurized TEOAE data showed significant differences across all 5 frequencies (p < 0.01). The pressurized protocol generated TEOAE responses presenting larger S/Ns, and a positive additive effect of approximately 2.31 dB was observed at all tested frequencies. There were no significant GE effects on the pressurized TEOAE responses. In terms of performance, both protocols performed equally (same number of PASSes). CONCLUSION The pressurized TEOAE protocol generates responses with higher S/Ns which might be useful in borderline cases where the middle ear status might cause a REFER screening outcome.

Abstract
OBJECTIVES To investigate the Barriers and Priorities accorded by hospital and health administrators to neo-natal hearing screening. METHODS This qualitative exploratory descriptive study employing purposive sampling technique was conducted in Islamabad, over a period of 18 months from 1st August 2015 to 31st January 2017. Sample included the stakeholders i.e., Heads of public sector hospitals of Islamabad including Pakistan Institute of Medical Sciences, Capital Hospital, and Federal Government Services Hospital, Islamabad. Study included in depth interviews using a self-structured interview guide and audio recording. Recorded data was transcribed followed by thematic analyses which was manually drawn and verified. RESULTS The Outcomes from thematic analysis were drawn as Planning, Essential requirements for NNHS, High risk screening, education, Existence of skilled maternal & newborn health workers. Hearing screening equipment//facility instrumentation, Logistic support, Health ministry support and Financial cover are also significant outcomes. Lack of awareness in the public and professionals regarding the importance of early identification of HI, poor health infrastructure, burden on tertiary care and lack of referral top the list of barriers to initiation of NNHS program at hospital administrative level. CONCLUSION The Barriers to NNHS identified at Hospital and Health care administrator level include lack of awareness, poor health infrastructure, burden on tertiary care and lack of referrals. Inherent barriers to NNHS cover the spectrum of lack of liaison/ linkages between obstetrics and other departments, deliveries at homes especially in rural areas, poor follow-up, scarcity of technical and adequately trained manpower. Intangible barriers to NNHS comprise lack of health care information system, attitudinal barriers, inadequate fiscal resources, and lack of integrated approach at intra departmental levels.

Abstract
OBJECTIVE The objective of this study was to establish the local incidence of hearing screening failure rate in newborns with all three stages of hypoxic ischemic encephalopathy (HIE). METHODS This retrospective cohort study was undertaken in a tertiary neonatal intensive care unit. Medical records and hearing secreening test results were collected for two years. RESULTS One hundred and ninety seven infants diagnosed with HIE, 20 of them died, 177 screened. Thirty five of 177 (19%) infants failed in screening test for hearing. Screening failure rate was 10/51 (19%), 20/105 (19%) and 5/21 (23%) in stage 1, 2 and 3, respectively and did not differ between HIE stages (p = 0.88). Furthermore failure rates were similar between infants who received therapeutic hypothermia or not (20% vs 19%, p = 0.84). CONCLUSION Hearing screening failure rate in HIE is quite high even in Stage 1 infants. Management and treatment of these infants should be made carefully concerning additional risks for hearing loss and long term follow-up even in Stage 1 HIE infants should be planned strictly.

Abstract
AIM Very preterm infants are at risk of neonatal hearing loss. However, it is unknown whether infants with a normal neonatal hearing screening result risk sensorineural hearing loss (SNHL) at a later age. METHODS This cohort study was conducted at the Erasmus Medical University Center Rotterdam, the Netherlands, on 77 very preterm infants born between October 2005 and September 2008. All infants underwent auditory brainstem response audiometry during neonatal hearing screening and at two years of corrected age. The frequency of SNHL in infants with a normal neonatal hearing screening was analysed and the risk factors associated with newly diagnosed SNHL in these infants were examined. RESULTS We found that 3.9% (3/77) of the very preterm infants showed permanent hearing loss during their neonatal hearing screening. In addition, a relatively high prevalence of newly diagnosed SNHL (4.3%) was found in three of the 70 infants followed up at the age of two. The total prevalence rate of permanent hearing loss in the cohort was approximately 8%. CONCLUSION A normal outcome of neonatal hearing screening did not guarantee normal hearing at two years of age in this very preterm cohort and paediatricians should be alert to the possibility of late-onset SNHL.

Abstract
Objectives Universal neonatal hearing screening (UNHS) started late in some underdeveloped areas in China, with relatively scarce screening resources and a wide regional distribution. This study aimed to compare the screening performance between rural and urban populations, and to examine the characteristics and problems of UNHS in underdeveloped regions in China. Methods A two-step hearing screening program was used in neonates born in Liuzhou Maternal and Child Health Hospital and in patients who were born in other hospitals, but admitted to the neonatal intensive care unit. This program involved distortion product otoacoustic emission and automated auditory brainstem response. Characteristics of each newborn, as well as the screening outcomes and performance were compared between rural and urban populations. Results A total of 19,098 newborns were screened with a referral rate of 17.9% at the first step. Sixty-three (0.33%) newborns had hearing loss. The prevalence of permanent hearing loss was 2.25‰. The average screening age was significantly older in the rural population than in the urban population in the first ( P < 0.01) and second steps of screening ( P < 0.05). The rural population had a higher referral rate in both steps than the urban population ( P < 0.01). The follow-up rate was much lower in the rural population than in the urban population ( P < 0.05), but dramatically increased in 2014 compared with the previous 2 years. Conclusions A low follow-up rate is a critical issue when carrying out UNHS in developing countries, such as China, especially for rural populations. The government should establish more hearing referral centres to increase service coverage and supply financial assistance for low-income populations.

Abstract
OBJECTIVE By comparing the Universal Neonatal Hearing Screening (UNHS) program as implemented in Shanghai and other regions in China and countries around the world, this study makes an assessment of the Shanghai model and summarizes the experiences implementing the UNHS program, so as to provide a valuable reference for other countries or regions to carry out UNHS more effectively. Since Shanghai is one of the most developed regions in China, we also examined the relationship between economic development and the UNHS starting year and coverage rate. METHODS The study conducted a systematic review of published studies in Chinese and English on the program status of neonatal hearing screening to compare and analyze the implementation of the UNHS program in 20 cities or provinces in China and 24 regions or countries around the world. The literature search in Chinese was conducted in the three most authoritative publication databases, CNKI (China National Knowledge Infrastructure), WANFANGDATA, and CQVIP (http://www.cqvip.com/). We searched all publications in those databases with the keywords "neonatal hearing screening" (in Chinese) between 2005 and 2014. English literature was searched using the same keywords (in English). The publication database included Medline and Web of Science, and the search time period was 2000-2014. RESULTS Shanghai was one of the first regions in China to implement UNHS, and its coverage rate was among the top regions by international comparison. The starting time of the UNHS program had no relationship with the Gross Domestic Product (GDP) per capita in the same year. Economic level serves as a threshold for carrying out UNHS but is not a linear contributor to the exact starting time of such a program. The screening coverage rate generally showed a rising trend with the increasing GDP per capita in China, but it had no relationship with the area's GDP per capita in selected regions and countries around the world. The system design of UNHS is the key factor influencing screening coverage. Policy makers, program administrators, and cost-sharing structures are important factors that influence the coverage rates of UNHS. CONCLUSION When to carry out a UNHS program is determined by the willingness and preference of the local government, which is influenced by the area's social, political and cultural conditions. Mandatory hearing screening and minimal-cost to no-cost intervention are two pillars for a good coverage rate of UNHS. In terms of system design, decision-making, implementation, funding and the concrete implementation plan are all important factors affecting the implementation of the UNHS.

Abstract
UNLABELLED Auditory neuropathy spectrum disorder (ANSD) is a particular kind of hearing disorder characterised by normal outer hair cell function and abnormal or absent auditory brain stem responses. Little data are available regarding the prevalence of this condition in healthy newborns. We performed a retrospective medical records review of 791 referrals from universal neonatal hearing screening (UNHS) at a well-baby clinic to investigate the prevalence of ANSD. Hearing screening was performed by automated auditory brain stem response (ABR) testing. A diagnosis of ANSD was established when ABR tracings were absent in the presence of otoacoustic emissions and/or a cochlear microphonic. Amongst 201 infants with confirmed congenital hearing loss, 13 infants were diagnosed with ANSD. The condition was unilateral in six and bilateral in seven infants. A risk factor for hearing loss could be identified in three infants. Abnormalities on magnetic resonance imaging were found in six infants; five of them had cochlear nerve deficiency. CONCLUSION The prevalence of ANSD was 6.5 % amongst well babies with confirmed congenital hearing loss identified through UNHS. The estimated incidence of ANSD in our population of newborns at the well-baby clinic was 0.09/1000 live births. Magnetic resonance revealed an underlying anatomical abnormality in about half of the patients. WHAT IS KNOWN • Auditory neuropathy dyssynchrony spectrum disorder (ANSD) is a particular form of hearing loss, mostly encountered in neonatal intensive care unit (NICU) graduates. • Little data are available on the prevalence and risk factors for ANSD in healthy newborns. What is new: • The estimated prevalence of ANSD in healthy newborns is 0.09/1000 live births. • In about half of the healthy newborns with ANSD, a structural abnormality was detected on magnetic resonance imaging of the posterior fossa/brain.

Abstract
AIM To detect any abnormality in the maturational process of hearing threshold during the early life in at-risk preterm infants. STUDY DESIGN The threshold of brainstem auditory evoked response was recorded and analyzed longitudinally from 30 to 42weeks of postconceptional age in 357 at-risk infants born at 23-36weeks of gestation. The results were compared with those in 82 low-risk infants born at 30-42weeks at various postconceptional ages. RESULTS From 31 to 42weeks, the response threshold in the at-risk infants was consistently slightly higher than that in the low-risk infants. No statistically significant difference was found between the two groups of infants at any designated postconceptional ages. The threshold in the at-risk infants born at 23-29weeks of gestation tended to be higher than those born at 30-36weeks at various postconceptional ages, but the difference did not reach statistical significance. There was also no significant difference in the slope of BAER threshold-age function between the at-risk infants, irrespective of gestational ages, and the low-risk infants. CONCLUSION During the early life, hearing threshold in at-risk preterm, mainly very preterm, infants is marginally elevated, but the maturational process of the threshold is generally similar to that in low-risk infants, without notable abnormality.

Abstract
We discuss issues related to cochlear implantation in children with auditory neuropathy spectrum disorder (ANSD). We describe the varied nature of this disease category including the numerous potential causes of auditory neuropathy. The most prevalent etiology for infants with ANSD is associated with prolonged neonatal intensive care unit (NICU) stay. We discuss the potential contribution of cochlear hypoxia to this etiology. The second part of this review describes in detail our own experience at the Hospital for Sick Children in Toronto, with cochlear implantation of children diagnosed with ANSD. We outline the detection, diagnosis, and referral routes for our patients. We provide an overview of our "standard operation procedures" regarding candidacy, and discuss some of the special considerations that need to be applied to children with ANSD. This includes decisions to implant children with better audiometric thresholds that are standard in non-ANSD patients, concerns about the possibility of spontaneous remission and the appropriate timing of implantation. Finally we review an extensive published literature in outcomes after cochlear implantation (CI) in ANSD. This is not a systematic review but rather an exercise to distill out some important reoccurring themes and the general consensus of opinion to date. Our conclusion is that the hearing loss category ANSD, together with its numerous co-morbidities, is far too heterogeneous to make definitive statements about prognosis with CI.

Abstract
AIM This study aimed to describe changes in hearing thresholds in babies born below 30 weeks of gestation at 28-42 weeks of postconceptional age, detect differences between gestational ages and explore the prevalence of hearing impairment. METHODS The threshold of brainstem auditory evoked response (BAER) was obtained longitudinally at 28-42 weeks of postconceptional age in 71 babies born at 23-29 weeks of gestation. RESULTS The BAER threshold was 28 decibels above normal hearing level (dB nHL) at 28 weeks of postconceptional age and decreased to 13 dB nHL at 39-42 weeks. The threshold was slightly higher in babies born at 23-26 weeks of gestation than in those born at 27-29 weeks at most postconceptional ages studied. From 28 to 36 weeks, the threshold decreased at 0.98 dB/week. At term, BAER threshold elevation (>20 dB nHL) occurred in 12 (16.9%) of the 71 babies. CONCLUSION The hearing threshold of babies born at 23-29 weeks of gestation decreased from 28 dB at 28 weeks of postconceptional age to 13 dB at 42 weeks. There were no major differences between gestational ages. During the preterm period, the threshold changed at around 1 dB/week. At term, one in six babies had hearing impairment.

Abstract
INTRODUCTION The implementation of Neonatal Hearing Screening (NHS) program is still at the preliminary stage particularly in developing countries despite the burden of permanent congenital and early-onset hearing impairment. There has been an earlier report of NHS in a city in Nigeria, however, this is a report of a preliminary NHS carried in a rural/sub-urban area in Nigeria. METHOD This prospective study, which took place between October 2009 and April 2010, involved all newborns delivered at the University College Hospital, Ibadan and the Bilal Missionary Maternity, Agodi, Ibadan, a small maternity service located in Agodi community serving predominantly low socioeconomic class people. All the neonates delivered during the study period were included in the screening. The screening was performed within 72 h of delivery using automated auditory brainstem response (AABR) and repeated after 6 weeks among those with referral result. Subsequently the neonates were referred to diagnostic audiology. RESULT Among the 453 newborns (231 males and 222 female), AABR screening showed referral, in 43.7% of neonates. At first screening, 224 (49.4%) were referred while 229 (50.6%) passed, however, during the post-natal period 40/229 (17.5%) reported for second screening, out of these 26 showed pass to the screening. This gave a total pass of 255/453 (56.3%). The presence of maternal pre-ecclampsia (P = 0.05) was found to be a significant morbidity factor associated with referral in the screening, while parental socioepidemiological variables; and the neonates' birthweight, gestational age and APGAR score were not. CONCLUSION The proportion of referral on hearing screening encountered was far higher than previously reported, however, continuation of infant screening in future should be comprehensive with viral and genetic analysis in order to address the issue of aetiologic diagnosis; in addition, the implementation should factor the high drop out from the first stage screening in order to substantiate the findings in our region.

Abstract
OBJECTIVES Measuring parent satisfaction with neonatal hearing screening programs is one of the most important indicators for assessing the quality and effectiveness and a useful instrument to identify service shortfalls. The aims of this study were to translate and adapt Parent Satisfaction Questionnaire with Neonatal Hearing Screening Programs (PSQ-NHSPs) to Persian language, determine the validity and reliability of this translation, and determine the level of parent satisfaction with neonatal hearing screening programs in Iran. METHODS Translated Persian version of the original English PSQ-HNSPs was presented to 138 parents whose children had received hearing screening before discharge from hospital. RESULTS The majority of parents responded strongly agree or agree to all dimensions of the questionnaire: overall satisfaction (90.6%), personnel in charge of hearing test (60.1%), and appointment activities (58%). Good internal consistency reliability (a=0.89) and moderate test-retest reliability (r=0.61) of the Persian version of PSQ-NHSPs were indicated. Construct validity was demonstrated by a significant positive relationship between overall satisfaction and specific dimensions in the questionnaire. CONCLUSION The Persian version of PSQ-NHSPs is a valid and reliable tool to assess the level of parent satisfaction with neonatal hearing screening programs.

Abstract
UNLABELLED Deafness is commonest curable childhood handicap. Most remedies and programmes don't address this issue at childhood level leading to detrimental impact on development of newborns. Aims and objectives are (A) screen all newborns for deafness and detect prevalence of deafness in children less than 2 years of age. and (B) assess efficacy of multi-staged OAE/ABR protocol for hearing screening. METHODOLOGY Non-randomized, prospective study from August 2008 to August 2011. All infants underwent a series of oto-acoustic emission (OAE) and final confirmatory auditory brainstem evoked response (ABR) audiometry. Finally, out of 1,101 children, 1,069 children passed the test while 12 children had impaired hearing after final testing, confirmed by ABR. Positive predictive value of OAE after multiple test increased to 100 %. OAE-ABR test series is effective in screening neonates and multiple tests reduce economic burden. High risk screening will miss nearly 50 % deaf children, thus universal screening is indispensable in picking early deafness.
