RESUMO
Objectives: This research aims to assess the effectiveness and cost-effectiveness of pre-pregnancy deafness screening policies. Methods: Married couples from Shanghai, Beijing, and Suzhou in China were enrolled. We conducted high-throughput, pre-pregnancy genetic screenings for deafness in women and their partners. We compared the cost-effectiveness of deafness genetic screening with the status quo. The two-step screening (wife then partner) and following treatments and interventions were included in the decision tree model. We conducted a cost-effectiveness analysis based on the decrease in deaf newborns, healthy newborn births, and cost-utility analysis of pre-pregnancy deafness genetic screening separately. Cost, utility, and probability data used in the three models were collected from a survey combined with literature and expert consultants. A 5% discount rate and a series of one-way sensitivity analyses along with a Monte Carlo simulation were used to test the reliability of this research. Results: Between Jan 1, 2019, and Dec 31, 2021, we recruited 6,200 females and 540 male spouses from community health service centers in Shanghai, Beijing, and Suzhou. The incremental cost-effectiveness ratio (ICER) for reducing deaf newborn births was USD 32,656 per case and USD 1,203,926 per case for increasing one healthy newborn birth. This gap exists because of the overall decrease of newborn births. From the perspective of the whole society, deafness genetic screening is not cost-effective for reducing the overall quality-adjusted life years (QALY) in the population. Discussion: Pre-pregnancy genetic testing is effective in decreasing the occurrence of congenital deafness. It is a cost-saving measure when compared with the costs of future medical expenditure and income loss for the affected families. However, such screening and preventive avoidance of pregnancy will decrease the population size and QALY. Only post-screening ART with PGT was shown to increase the birth of healthy newborns. Focusing on key groups such as premature births or consanguineous couples may improve the societal effects of screening.

The COVID-19 pandemic placed stress on all aspects of the educational system. Many state departments of education acknowledged the disruption to individualized education program evaluation and implementation but insisted that evaluation timelines and services continue undisrupted. School psychologists were therefore forced to navigate the viability of virtual assessment without established research supporting this type of student evaluation. Formal assessments used in the identification of learning disabilities and other areas of disability were not standardized with virtual administration procedures; however, many test publishers have offered guidelines for online administration. These guidelines may not be suitable for test administration with deaf and hard of hearing (DHH) children. Through the presentation of two case studies, this article explores some of the available administration guidelines and evaluates their appropriateness for use with DHH children. Information in this article informs current practice of school psychology in a virtual environment.

OBJECTIVES: The purpose of this study was to (1) develop a Language-independent Test of Auditory Discrimination (LIT-AD) between speech sounds so that people with hearing loss who derive limited speech perception benefits from hearing aids (HAs) may be identified for consideration of cochlear implantation and (2) examine the relationship between the scores for the new discrimination test and those of a standard sentence test for adults wearing either HAs or cochlear implants (CIs). DESIGN: The test measures the ability of the listener to correctly discriminate pairs of nonsense syllables, presented as sequential triplets in an odd-one-out format, implemented as a game-based software tool for self-administration using a tablet computer. Stage 1 included first a review of phonemic inventories in the 40 most common languages in the world to select the consonants and vowels. Second, discrimination testing of 50 users of CIs at several signal to noise ratios (SNRs) was carried out to generate psychometric functions. These were used to calculate the corrections in SNR for each consonant-pair and vowel combination required to equalize difficulty across items. Third, all items were individually equalized in difficulty and the overall difficulty set. Stage 2 involved the validation of the LIT-AD in English-speaking listeners by comparing discrimination scores with performance in a standard sentence test. Forty-one users of HAs and 40 users of CIs were assessed. Correlation analyses were conducted to examine test-retest reliability and the relationship between performance in the two tests. Multiple regression analyses were used to examine the relationship between demographic characteristics and performance in the LIT-AD. The scores of the CI users were used to estimate the probability of superior performance with CIs for a non-CI user having a given LIT-AD score and duration of hearing loss. RESULTS: The LIT-AD comprises 81 pairs of vowel-consonant-vowel syllables that were equalized in difficulty to discriminate. The test can be self-administered on a tablet computer, and it takes about 10 min to complete. The software automatically scores the responses and gives an overall score and a list of confusable items as output. There was good test-retest reliability. On average, higher LIT-AD discrimination scores were associated with better sentence perception for users of HAs (r = -0.54, p <0.001) and users of CIs (r = -0.73, p <0.001). The probability of superior performance with CIs for a certain LIT-AD score was estimated, after allowing for the effect of duration of hearing loss. CONCLUSIONS: The LIT-AD could increase access to CIs by screening for those who obtain limited benefits from HAs to facilitate timely referrals for CI candidacy evaluation. The test results can be used to provide patients and professionals with practical information about the probability of potential benefits for speech perception from cochlear implantation. The test will need to be evaluated for speakers of languages other than English to facilitate adoption in different countries.

THE AIM OF THE STUDY: Was to study the possibility of using a battery of psychoacoustic tests to assess the tuning of the cochlear implant processor (CI) in deaf patients. METHODOLOGY: The study involved 60 prellingually deaf patients aged 10 to 23 years with oral speech skills. To assess the quality of the CI processor tuning, in addition to traditional methods, a special battery of psychoacoustic tests was used. The first block of tests assessed the perception of the basic characteristics of sound signals (duration, temporal structure, spectrum, timbre) and was used to assess the initial setting. The second block of tests, intended for patients with experience using CI, included tasks to distinguish acoustically similar and dynamically changing signals, etc. RESULTS: At the end of the initial CI setup session, patients with short signal perception problems were identified. Adjusting the frequency of electrical stimulation in patients has increased their ability to distinguish between sounds. During the second tuning session of the CI processor, 6 months later, a group of patients with difficulties in perceiving acoustic information in the low-frequency range was identified - distinguishing melodic intervals, changing the pitch of sounds, highlighting the voice of the target speaker. The «problem¼ patients underwent additional correction of the CI processor setting and the corresponding auditory training, which improved the test performance and subjective perception of sounds. CONCLUSION: The use of psychoacoustic tests expands the possibilities of fine tuning the CI processor, taking into account the individual characteristics of the patient's auditory perception at different stages of CI use, especially in «problem¼ patients.

The cochlear implant (CI) has an effective habilitation modality for hearing-impaired children by promoting sound perception, vocalization, and language ability. However, the major challenge that remained was the lack of assessment standards for pediatric CI users, especially prelingually deaf children, to evaluate hearing rehabilitation effectiveness. In the present study, we conducted an oddball paradigm with stimuli varying in pure-tone, syllable, and tonal sounds. After implantation, we utilized cortical auditory evoked potential (CAEP) and mismatch negativity (MMN) to obtain time-domain analysis; meanwhile, the source localization was investigated to obtain spatial accuracy of the plasticity in the auditory cortex. P1 started to emerge at the third month after implantation, but its peak level was not significant until the sixth month. The temporal lobe was activated between the third and sixth months after implantation. The MMN waveform was basically normal approximately after 12 months. These results suggest that the auditory system goes through a critical period of rapid development between three and six months and enters a maturation period after 12 months. This work indicates that CAEPs are more suitable for assessing the early auditory system reconstruction, while MMN performs better in evaluating the advanced auditory function. Furthermore, source localization has proven to be an efficient tool in exploring auditory cortex plasticity, especially for pediatric CI users.

Over the past few decades, there has been an increasing shift toward emphasizing the importance of the child's family taking an active role in the habilitation process through family-centered early intervention (FCEI) programs. Accordingly, the Health Professions Council of South Africa recommends that early intervention services following confirmation of hearing loss must be family-centered within a community-based model of service delivery that is culturally congruent. The aim of this study was to explore and document current evidence reflecting trends in FCEI for children who are deaf or hard of hearing (DHH) by identifying and describing current practice models and/or processes of FCEI for these children. This study describes our first steps in formulating a framework for FCEI for children who are DHH in South Africa. An integrative literature review was conducted. Sage, Science Direct, PubMed, and Google Scholar databases were searched for studies published in English between January 2009 and January 2019 reporting on FCEI programs for children who are DHH. Studies that focused on the following were excluded from the study: speech and language outcomes of children, youth, and adults who are DHH; education for children who are DHH; universal newborn hearing screening; professionals' roles in early hearing detection and intervention; diagnosis of hearing loss; and sign language. Kappa statistics were performed to determine agreement between reviewers. Twenty-two studies were included in the review. Cohen's kappa revealed a substantial agreement (κ = 0.8) between reviewers for data extraction and synthesis in terms of the articles that met the criteria for inclusion in the review. Findings were discussed under 5 themes: caregiver involvement; caregiver coaching/information sharing; caregiver satisfaction; challenges with FCEI; and telehealth. Generally, there is sufficient evidence for FCEI, with caregivers indicating the need for full involvement in their children's care. Methods of caregiver involvement involving caregiver coaching/information sharing need to be culturally and linguistically appropriate, with sensitivities around time and manner. This increases caregiver satisfaction with intervention programs and improves outcomes for children who are DHH. Challenges identified by the studies raise implications for early hearing detection and intervention programs, as well as Departments of Health and Social Welfare. These included logistical challenges, professional-related challenges, and caregiver-related challenges. Various aspects of FCEI have been reported in the review. Findings of these studies have significant implications for the formulation of quality FCEI programs to ensure contextually relevant and contextually responsive care of children who are DHH.

The development of pragmatic skills does not often receive attention by professionals who are recommending or undertaking assessment of deaf and hard of hearing (DHH) children, yet social communication is vital for linguistic, social, emotional, and academic development. We acknowledge the challenges that DHH children have with pragmatic skills, advocate for monitoring of pragmatic development for all DHH children by medical professionals, and provide direction for assessment of pragmatic skills in young DHH children, particularly for clinicians and teachers who are tasked with that work. Pragmatic assessment is challenging because it must involve observations of the child in interaction with a communication partner, either directly during a specific interaction or through the reflections of a familiar adult. In this article, we recommend two complementary assessment procedures for young DHH children who use spoken language. Assessment 1 recommends that a parent or caregiver completes The Pragmatic Checklist to provide a picture of the child's functional communication. In assessment 2, the information gained through the checklist is complemented by using direct observations of a child in interaction with an adult or a peer. The Pragmatic Protocol uses a video-recorded conversation sample between the child and familiar person that is analyzed by a DHH professional for 30 different pragmatic behaviors. We conclude this article with a recommendation for pediatricians and health care professionals to monitor pragmatic developmental milestones in DHH children, to refer them for pragmatic assessments, and to collaborate with researchers to develop valid, reliable tools that adequately capture the pragmatic skill strengths and needs of DHH children.

OBJECTIVES: The aim of the present study was to compare the vestibular system integrity of individuals with normal hearing with that of prelingual hearing impaired individuals. It is well known that ocular vestibular evoked myogenic potentials (oVEMPs) reflect utricular function, whereas cervical vestibular evoked myogenic potentials (cVEMPs) reflect saccular function. Therefore, oVEMP and cVEMP tests were applied to evaluate the vestibular system integrity of hearing impaired individuals participating in the research. MATERIALS AND METHODS: The study group consisted of sensorineural prelingual hearing-loss volunteers aged from 18 to 60 years, whereas the control group consisted of age- and gender-matched healthy volunteers. cVEMP and oVEMP tests were performed to evaluate the integrity of the vestibular system, and the results were compared with those of the control group. RESULTS: The study included 20 (76.9%) women and 6 (23.1%) men in the study group; on the other hand, the control group consisted of 19 (73.1%) women and 7 (26.9%) men. There was a difference between the study group and the control group when oVEMP and cVEMP responses were compared, and the response percentage was higher in the control group. The response rates of oVEMP and cVEMP in patients with prelingual hearing loss were 44.2% and 59.6%, respectively. There was also a statistically significant difference between the groups for oVEMP amplitude and cVEMP P1 latency (p≤0.05). CONCLUSION: These findings suggest that prelingual hearing loss is related to both utricular and saccular dysfunctions. However, oVEMPs were more often abnormal in prelingual deaf patients than cVEMPs, suggesting that utricular dysfunction may be more common than saccular dysfunction.

Importance: Currently, no clear guidelines exist regarding clinical testing methods for identifying adult cochlear implant (CI) candidates. Indications provided by the US Food and Drug Administration, Medicare, and private insurers are ambiguous concerning test materials and the level and mode of test presentation. This could lead to wide variability in clinical assessment and, potentially, unequal access to CIs for individuals with clinically significant hearing loss. Objective: To examine the preoperative testing methods used by audiologists in evaluating adult CI candidates across the United States. Design, Setting, and Participants: A survey assessing audiology practice patterns was created using a Research Electronic Data Capture system hosted at the University of Miami. A link to a survey (65 questions in multiple-choice or rank-order format was distributed electronically along with a request for completion to members of the American Cochlear Implant Alliance and to the Institute for Cochlear Implant Training forum. Responses were collected from January 17 to June 4, 2018. Participation was limited to audiologists who evaluate adult CI candidates, and respondents who do not provide adult CI care were excluded. Collected demographic information included work setting, years of experience, and highest level of education attained. Main Outcomes and Measures: Percentages, medians, and interquartile ranges were from aggregated responses concerning hearing aid verification methods; testing methods, materials, and practices; nonauditory factors that might affect CI candidacy; audiology practice patterns; and expanded indications for CIs. Results: Anonymized surveys were returned by 99 respondents; because surveys were available electronically, the number of audiologists who viewed the survey but did not respond was not available. Seven respondents identified themselves as pediatric specialists and were excluded, resulting in a total of 92 surveys available for analysis (denominators vary because respondents could complete the survey without answering all questions). Seventy percent of respondents (51 of 72) were doctors of audiology, and nearly 50% (33 of 74) were employed at universities and academic centers performing more than 50 CIs per year. When assessing adult candidacy for implant, most respondents reported using test materials from the Minimum Speech Test Battery: 96% (51 of 53), using AzBio sentences in quiet; 89% (47 of 53), AzBio sentences in noise; and 100% (53 of 53), the consonant-vowel nucleus-consonant, monosyllabic words test. However, these tests were applied inconsistently, with 39 of 53 respondents (74%) reporting use of a sound pressure level scale and the other 14 (26%) a hearing level scale at various decibel levels, and with some using a single signal-to-noise ratio and others using multiple ratios for sound-in-noise tests. Respondents' definitions of the best aided listening condition for assessing implant candidates also varied widely. Among the nonauditory factors ranked most important for assessing CI candidacy were patient's level of cognition and expectations of CI; yet, few respondents reported including cognitive or psychological tests in the assessment protocol. Conclusions and Relevance: Findings of this study reveal considerable variability in preoperative testing methods and practices across health care professionals assessing adult candidates for CI. This lack of standardization in the delivery of care may increase the risk for health care inequities, specifically in access to care for adults with clinically significant hearing loss.

OBJECTIVE: To estimate the screening coverage of neonatal bilateral permanent deafness (NBPD) among neonates in the region of Paris (Île-de-France), between 2012 and 2017, using data from the Program for Medicalization of Information System (PMSI). METHOD: The study population covers hospital stays of newborns (0 to 28 days of life) in the region of Paris between 2012 and 2017. The data were extracted from PMSI database using DIAMANT system. The annual screening coverage rate is estimated by the ratio between the number of newborn stays with the code Z13.51 and one of the two specific medical procedures for NBPD screening and the number of live births recorded in health facilities. RESULTS: In 2017, 133 152 newborn stays with a Z13.51 code were counted in the Ile-de-France region, out of 178 011 live births; less than 75% of newborns. Hospital stays including a medical procedure CDQP009 or CDQP017 represent a proportion of 16.3% in 2017. The annual estimated rate of screening coverage of NBPD using the PMSI (89,8%, taking into account the different coding practices) is lower than the one calculated from data of the FPDPHE (95,5%) and national/regional target rate set by the National screening Program. CONCLUSION: Our methodology and the observed results revealed that an annual NBPD screening coverage rate could be estimated, if the National plan and coding practices requirements follow the guidelines. Harmonization of coding practices and data quality assurance are essential to be able to build an indicator of NBPD screening coverage based on routinely collected data (PMSI, SNDS), which can contribute to the monitoring of the implementation of the screening program for the neonates.

ABSTRACT Objective: to analyze the perceptions of deaf individuals about the communication process with health professionals of the state of Rio de Janeiro. Methods: cross-sectional observational study. Data were collected through the application of a questionnaire with quantitative and qualitative questions to 121 deaf adults. Objective responses were studied descriptively through frequency tables and analyzed by inferential statistics and logistic regression. The data from the open questions were analyzed through content analysis. Results: the lack of interpreters and the lack of use of the Brazilian Sign Language by professionals were perceived as the main communication barriers. In turn, the presence of companions who are listeners (73%) and the use of mime/gestures (68%) were among the strategies most used by the deaf. The majority of deaf people reported insecurity in consultations, and those who best understood their diagnosis and treatment were the bilingual deaf (p = 0.0347) and the deaf who used oral communication (p = 0.0056). Conclusion: communication with the professionals was facilitated when the deaf people had a companion or when they used mimics and gestures. Sign language was neglected, despite the fact that the provision of care to the deaf by professionals trained to use this language is guaranteed in the legislation.
RESUMO Objetivo: analisar as percepções de indivíduos com surdez em relação ao processo comunicacional com profissionais de saúde da Atenção Básica do Estado do Rio de Janeiro. Métodos: estudo observacional transversal. A coleta de dados foi feita através da aplicação de questionário com perguntas quantitativas e qualitativas a 121 surdos adultos. As respostas objetivas foram estudadas descritivamente através de tabelas de frequência e analisadas por estatísticas inferenciais e de regressão logística. E, para os dados oriundos de questões abertas, foi realizada uma análise de conteúdo. Resultados: a falta de intérprete e a não utilização da Língua Brasileira de Sinais pelos profissionais foram percebidas como principais barreiras comunicacionais. Já a presença de acompanhante ouvinte (73%) e o uso de mímicas/gestos (68%) estão entre as estratégias mais utilizadas pelos surdos. A maioria dos surdos relatou insegurança após as consultas e os que melhor compreenderam seu diagnóstico e tratamento foram os surdos bilíngues (p=0,0347) e os oralizados (p=0,0056). Conclusão: a comunicação com os profissionais foi facilitada quando os surdos estavam com acompanhante ou quando utilizavam mímicas e gestos, sendo a língua de sinais negligenciada, apesar da legislação garantir aos surdos atendimento por profissionais capacitados para o uso desta.

OBJECTIVE: To assess the imaging findings of computed topography (CT) and magnetic resonance imaging (MRI) in adults with postlingual deafness and otherwise normal clinical history and physical exam. Additionally, determine the influence and implications of these findings with respect to surgical outcomes and cost. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral hospital. PATIENTS: Adults with postlingual deafness with no history of prior ear surgery, chronic ear disease, meningitis, otosclerosis, or head trauma. INTERVENTIONS: Cochlear implantation of 1 or both ears, with preoperative CT, MRI, or both. MAIN OUTCOME MEASURES: Imaging results were classified as normal, abnormal affecting surgery, incidental requiring follow-up, or incidental not requiring follow-up. Average cost of each imaging modality was determined. RESULTS: A total of 128 patients met the inclusion criteria. Of these, 82 (64.1%) had both CT and MRI performed, 33 (25.8%) had CT, and 13 (10.2%) had MRI prior to cochlear implant (CI). Scans were normal in 125 (97.7%) of cases. Of the remaining 3 (2.3%) patients, there were incidental findings requiring follow-up. All implants were placed successfully, and in no instance did the results of the scan influence the surgery. The average cost of imaging per patient was $4707. CONCLUSION: In adults with postlingual deafness with an otherwise benign clinical history, CT and MRI are unlikely to affect or preclude surgery. With new MRI safe cochlear implants, imaging can be performed safely postoperatively if needed.

Abstract Introduction: Cochlear implants are undeniably an effective method for the recovery of hearing function in patients with hearing loss. Objective: To describe the preoperative vestibular assessment protocol in subjects who will be submitted to cochlear implants. Methods: Our institutional protocol provides the vestibular diagnosis through six simple tests: Romberg and Fukuda tests, assessment for spontaneous nystagmus, Head Impulse Test, evaluation for Head Shaking Nystagmus and caloric test. Results: 21 patients were evaluated with a mean age of 42.75 ± 14.38 years. Only 28% of the sample had all normal test results. The presence of asymmetric vestibular information was documented through the caloric test in 32% of the sample and spontaneous nystagmus was an important clue for the diagnosis. Bilateral vestibular areflexia was present in four subjects, unilateral arreflexia in three and bilateral hyporeflexia in two. The Head Impulse Test was a significant indicator for the diagnosis of areflexia in the tested ear (p = 0.0001). The sensitized Romberg test using a foam pad was able to diagnose severe vestibular function impairment (p = 0.003). Conclusion: The six clinical tests were able to identify the presence or absence of vestibular function and function asymmetry between the ears of the same individual.
Resumo Introdução: Os implantes cocleares (IC) são indiscutivelmente um método eficaz de recuperação da função auditiva de pacientes surdos. Objetivo: Descrever o protocolo de avaliação vestibular pré-operatória em sujeitos que serão submetidos ao IC. Método: Nosso protocolo institucional prevê o diagnóstico vestibular por meio de seis testes simples: testes de Romberg e Fukuda, nistagmo espontâneo, Head Impulse Test, Head Shaking Nistagmus, prova calórica. Resultados: Foram avaliados 21 pacientes com média de 42,75 ± 14,38 anos. Apenas 28% da amostra apresentaram todos os testes normais. A presença de informação vestibular assimétrica foi documentada pela prova calórica em 32% da amostra e o nistagmo espontâneo mostrou-se pista importante para seu diagnóstico. A arreflexia vestibular bilateral foi diagnosticada em quatro sujeitos; arreflexia unilateral em três e hiporreflexia bilateral em dois. O Head Impulse Test mostrou-se indicador significante (p = 0,0001) para diagnosticar arreflexia da orelha testada. O teste de Romberg sensibilizado em almofada foi capaz de diagnosticar os comprometimentos severos da função vestibular (p = 0,003). Conclusão: Os seis testes clínicos foram capazes de identificar a presença ou não de função vestibular e assimetria da função entre as orelhas de um mesmo indivíduo.

The spatial auditory change complex (ACC) is a cortical response elicited by a change in place of stimulation. There is growing evidence that it provides a useful objective measure of electrode discrimination in cochlear implant (CI) users. To date, the spatial ACC has only been measured in relatively experienced CI users with one type of device. Early assessment of electrode discrimination could allow auditory stimulation to be optimized during a potentially sensitive period of auditory rehabilitation. In this study we used a direct stimulation paradigm to measure the spatial ACC in both pre- and post-lingually deafened adults. We show that it is feasible to measure the spatial ACC in different CI devices and as early as 1 week after CI switch-on. The spatial ACC has a strong relationship with performance on a behavioural discrimination task and in some cases provides information over and above behavioural testing. We suggest that it may be useful to measure the spatial ACC to guide auditory rehabilitation and improve hearing performance in CI users.

OBJECTIVE: The aims of this study were: to investigate the referral rates of postlingually deafened adult cochlear implant (CI) candidates from a hearing aid (HA) clinic for a CI candidacy assessment and to gain insight about factors influencing the referral pathways to CI assessments. DESIGN: Two methodologies were used: a retrospective cohort study reviewing clinical files and a questionnaire to clinicians. STUDY SAMPLE: The files of 1249 adult clients from the HA clinic who had average puretone hearing thresholds greater or equal to 65 dB HL in the better hearing ear and unaided phoneme recognition scores of less than 50% in both ears were reviewed. All of the clinicians completed the online questionnaire. RESULTS: Eighteen adults met the CI candidacy criteria, of whom 16 (89%) had a CI discussion with their audiologist, with 11 (61%) being referred for a CI evaluation. Of these 11, four proceeded to implantation. Questionnaire responses revealed the need for better information on candidacy and referral guidelines for HA audiologists, in addition to enhanced communication between HA and CI clinics. CONCLUSIONS: Overall the results indicate that the referral pathway to obtain a CI assessment is a barrier contributing to the low CI penetration rate in adults.

Importance: Barriers to early pediatric cochlear implantation in underinsured populations have been previously reported. However, to our knowledge, the effect of this delay on the development of auditory and speech-language objectives has not been evaluated. Objective: To determine if health care insurance status affects the achievement of proficiency in basic sound access and imitation tasks in children with cochlear implants. Design, Setting, and Participants: A retrospective review of 123 children aged 1 to 12 years receiving cochlear implants at the single tertiary referral academic free-standing Children's National Health System in Washington, DC, between January 1, 2008, and December 31, 2015. Main Outcomes and Measures: Auditory function after cochlear implantation, time to proficiency in Ling-6 scores, and number of speech therapy and audiological appointments, as well as current educational setting, were compared with patient age at diagnosis of hearing loss, age at cochlear implantation, cochlear implantation insertion technique, and health care insurance status for recipients of cochlear implants. Results: A total of 123 children aged 1 to 12 years (mean [SD] age, 64.0 [57.4] years) with cochlear implants were included in the study. Of 37 patients with complete and accurate Ling-6 test scores, 23 (62.1%) were able to have proficiency a mean of 5.1 months at follow-up. Despite equal auditory performance on pure-tone audiometry after cochlear implantation, publicly insured recipients had Ling-6 proficiency a mean of 6.0 months (95% CI, 5.5-6.5 months) later than privately insured recipients (11.0 vs 5.0 months). When controlling for patient age, time to cochlear implantation, number of therapy sessions, and cochlear implantation insertion technique, multivariable logistic regression analysis revealed health care insurance status to be the independent variable associated with inadequate Ling-6 discrimination scores (odds ratio, 46.2; 95% CI, 2.9-729.4). Conclusions and Relevance: Despite equal speech detection scores, publicly insured recipients of cochlear implantation had a significant and critical delay in attaining proficiency in a fundamental measure of sound recognition and imitation.

INTRODUCTION: Cochlear implants are undeniably an effective method for the recovery of hearing function in patients with hearing loss. OBJECTIVE: To describe the preoperative vestibular assessment protocol in subjects who will be submitted to cochlear implants. METHODS: Our institutional protocol provides the vestibular diagnosis through six simple tests: Romberg and Fukuda tests, assessment for spontaneous nystagmus, Head Impulse Test, evaluation for Head Shaking Nystagmus and caloric test. RESULTS: 21 patients were evaluated with a mean age of 42.75±14.38 years. Only 28% of the sample had all normal test results. The presence of asymmetric vestibular information was documented through the caloric test in 32% of the sample and spontaneous nystagmus was an important clue for the diagnosis. Bilateral vestibular areflexia was present in four subjects, unilateral arreflexia in three and bilateral hyporeflexia in two. The Head Impulse Test was a significant indicator for the diagnosis of areflexia in the tested ear (p=0.0001). The sensitized Romberg test using a foam pad was able to diagnose severe vestibular function impairment (p=0.003). CONCLUSION: The six clinical tests were able to identify the presence or absence of vestibular function and function asymmetry between the ears of the same individual.

Public attitudes toward genetic testing are largely unknown. Furthermore, as medical practices vary widely among different regions around the world due to differences in cultural, sociopolitical, and economical environments, people from different regions may have drastically different attitudes. Even for the same individual, the attitude may vary depending on the purpose and type of genetic testing and the disorder to be tested for. It seems to me what is called for is a "precision" approach to gauging people's attitude toward genetic testing. In the current issue of the American Journal of Medical Genetics: Part A, Fu et al. reported a carefully designed study that began to fill this gap, although more work need to be done for different disorders and among other populations. © 2016 Wiley Periodicals, Inc.

OBJECTIVE: In contrast to previous clinical practice, current guidelines recommend bilateral cochlear implantation in children, resulting in a cohort of children who initially received one implant, but have subsequently had a second, contralateral implant. This study aimed to explore satisfaction and quality of life in children implanted simultaneously or sequentially. DESIGN: A novel measure of satisfaction and quality of life following paediatric bilateral cochlear implantation (the Brief Assessment of Parental Perception; BAPP) was developed and preliminary validation undertaken as part of a large, national project of bilateral implantation. Children's parents completed the measure yearly for up to three years following implantation. STUDY SAMPLE: Children from 14 UK implant centres were recruited into the study; data were available for 410 children one year post-implantation. RESULTS: The BAPP was found to have good face and convergent validity, and internal consistency. Results indicated very high levels of satisfaction with the devices, and improvements in quality of life. However there was evidence that children implanted sequentially were less willing to wear their second implant in the first two years than those children receiving simultaneous implants. CONCLUSION: Simultaneous and sequential cochlear implants have a positive impact on the quality of life of deaf children.

The authors address considerations and promising practices relating to assessment of d/Deaf and Hard of Hearing Multilingual Learners. DMLs' unique culture(s), language(s), and learning needs must be considered when assessments of this population are being planned, conducted, and interpreted. The authors address theory and research on (a) general considerations for the overarching assessment process, (b) specific assessment approaches used to assess DMLs, and (c) assessment of language proficiency for diverse language learners. In addition, basic recommendations for the assessment of DMLs are made, including increased availability of assessments in various languages, use of multiple sources of individual and family data, assessment of all languages, and incorporation of a strong assessment component (that includes nondiscrimination practices) into teacher preparation programs.
