    Objective

    Hearing impairment is one of the sensory problems in children that affects various aspects of their lives and impacts their social skills (SS) and emotion regulation (ER).Research indicated that active play has a crucial role in children’s social and emotional development. In this regard, the present study aims to investigate the effectiveness of group active plays (GAP) on the SS and ER of children with hearing impairment.

    Methods

    This quasi-experimental study involved a pre-test/post-test design with a two-month follow-up. The participants included 7 to 12-year-old boys with hearing impairment enrolled in the deaf-hearing impaired schools (2022-2023). Thirty children were randomly assigned to an experimental group (n=15) and a control group (n=15). The experimental group participated in 12 interventional sessions, while the control group had the regular school program. Both groups completed SS and ER questionnaires (including before and after the intervention, and two months after the intervention [follow-up]). The data were analyzed using analysis of variance (ANOVA) with SPSS software, version 25.

    Results

    The results of this study indicated a significant difference between the control and experimental groups in SS (P<0.002). GAP also had a significant effect on ER (P<0.001). Moreover, it had a significant effect on liability/negativity which was one of the components of ER (P<0.022).

    Conclusion

    Based on the obtained results, it can be concluded that the implemented intervention (GAP) helped to improve SS, ER, and its component (liability/negativity) in children with hearing impairment. Coaches, teachers, and therapists can take steps to enhance SS and ER in children with hearing impairment by implementing GAP.

    According to the US Centers for Disease Control and Prevention (CDC) definition, genetic counseling is a process in which information is presented about how genetic conditions affect a patient or his/her family. A genetic counselor collects a patient’s personal and family health history to promote the family’s awareness and perception of specific genetic diseases, testing risks and advantages, disease management, and assessment of available therapeutic options. Intellectual disability (ID) and deafness are two common disabilities with considerable impacts on the quality of life of patients and their families. The present research has investigated the role of genetic counseling in the screening and prevention of deafness and ID based on the studies published in the Web of Science, PubMed, and Google Scholar databases between 2015 and 2023. Genetic counseling can be employed as an influential tool in screening, early diagnosis, and prevention of ID and deafness. Considering that many cases of ID and deafness are rooted in individual genetics, genetic counseling can help lessen the risk factors of developing these disabilities and improve the quality of individual and family life. The effect of genetic counseling, as an influential tool, on screening, early diagnosis, and prevention of ID and hearing loss is also assessed.

    Background

     Hearing impairment (HI), as the most prevalent sensorineural impairment, can affect both children and their families' quality of life (QOL) by its remarkable consequences, like parental stress (PS). It is a type of stress that parents perceive following their parent-child interactions, alongside the children's mental, physical, or developmental disturbances.

    Objectives

     Considering the significant catastrophic consequences of HI in both children and their families' QOL, the current cross-sectional and descriptive-correlational study was conducted to investigate the relationship between PS and QOL among Iranian parents of hearing-impaired children with cochlear implantation (CI) history.

    Methods

     A total of 80 parents of HI children with CI history participated in the current cross-sectional and descriptive-correlational study based on the inclusion criteria and simple random sampling. Therefore, their PS and QOL were evaluated using the "Questionnaire of Clinical and Demographic Information", the "Parenting Stress Index, Fourth Edition Short Form (PSI-4-SF)," and the "36-Item Short Form Survey (SF-36)." Eventually, SPSS version 26 was utilized to analyze the obtained data.

    Results

     Most of the 80 participants were female (85.0%), housewives (58.8%), and had bachelor's degrees (35.0%). Moreover, PS and QOL in parents of HI children with CI history were relatively low (�- = 67.42, P < 0.05) and relatively satisfactory (�- = 70.12, P < 0.05) respectively. Eventually, there was a significant (P = 0.001) and inverse correlation (r = -0.811) between PS and QOL in parents of HI children with CI history.

    Conclusions

     The level of PS in the parents of HI children with CI history had a strong and inverse correlation with their QOL. Also, at the time of the study, the stress level of the parents was relatively low, and their QOL was reported to be relatively satisfactory. Thus, examining the factors affecting PS and QOL will be effective in achieving permanent, stable outcomes.

    Objectives

    Studies have shown the high prevalence of dental caries, negligence of oral health, and unmet dental care needs among children with hearing impairment compared to their healthy peers. This study was conducted to determine the barriers to oral health of children with hearing impairment from the perspective of their mothers.

    Methods

    In this qualitative study, semi-structured interviews were conducted with 19 mothers based on purposive sampling in order to investigate the factors affecting compliance with oral health. Interviews were recorded, handwritten, coded and classified; and for content analysis, Graneheim and Lundman's qualitative approach was used.

    Results

    As a result of the data analysis, the three main themes of “the effects of general health status, the effects of instruction and learning, and problems in receiving dental health care services” were identified as barriers to good oral health. Moreover, nine sub-themes of “inadequate education regarding oral health, parental insufficient supervision, shortages in dentistry service delivery systems, obstacles hindering mother from pursuing services, lack of guidelines for offering free periodical dental examinations for children with special needs, the impact of improper nutritional habits on oral health, children’s mental problems, unfavorable oral health conditions, and the impact of oral health on the child’s general health" were obtained.

    Conclusion

    Inadequate education in the field of oral health and difficulties in receiving dental services were identified as the most important factors affecting oral health in children with hearing impairment from their mothers' perspective.

    سابقه و هدف

    نا شنوایی به عنوان شایع ترین اختلال حسی - عصبی، شناخته می شود. فراوانی اختلال شنوایی در جهان، یک از هر 500 نوزاد متولدشده می باشد. در ایران، به دلیل رواج ازدواج های خویشاوندی، این میزان دو تا سه برابر بیشتر برآورد می شود. ناهمگنی بالای لوکوسی و آللی نا شنوایی توارثی در جمعیت های مختلف ایران و پراکندگی مطالعات انجام شده، از دلایل اصلی انجام مطالعه مروری حاضر می باشد.

    مواد و روش ها: 

    مقالات منتشرشده در پایگاه های Google scholar، Scopus،Web of Science  و PubMed از سال 1989 تا 2022 براساس کلیدواژه های Iran، non-syndromic، hearing loss، gene، mutation و pathogenic variants جمع آوری و بررسی شد.

    نتایج

    تاکنون، بیش از 130 ژن عامل ناشنوایی غیر سندرومی (NSHL) در جهان شناخته شده است. از این میان، 57 ژن مشتمل بر 430 جهش بیماری زا و شبه بیماری زا در مبتلایان به ناشنوایی غیرسندرومی در ایران گزارش شده است. بر مبنای مطالعات انجام شده، ژن هایGJB2 ، SLC24A4، MYO15A، MYO7A، CDH23 و TMC1 در ایران به ترتیب از رایج ترین عوامل NSHL هستند که توزیع آن ها در جمعیت های مختلف، متفاوت می باشد. همچنین، جهش بدمعنی، رایج ترین جهش گزارش شده است.

    نتیجه گیری:

     این مطالعه ضمن تایید ناهمگنی ژنتیکی بالای NSHL در ایران، بر اهمیت و تاثیر انقلابی تکنیک های توالی یابی نسل جدید (NGS) در تشخیص علت ژنتیکی نقص شنوایی در جمعیت های مختلف ایران تاکید می کند. چنین رویکردی می تواند نقش قابل توجهی در انجام مشاوره ژنتیک، تشخیص قبل از تولد و مدیریت کلینیکی اختلال شنوایی در خانواده های مبتلا ایفا نماید.

    Background

    Hearing loss (HL) is known as the most common sensorineural disorder. The frequency of hearing impairment is one in every 500 infants born, worldwide. In Iran, due to the high prevalence of consanguineous marriages, this amount is estimated to be two to three times higher. The high locus and allelic heterogeneity of hereditary hearing loss in different populations of Iran and distribution of studies are the main reasons for conducting this review.

    Materials and Methods

    Published articles were collected and reviewed in Google scholar, Scopus, Web of Science and PubMed databases from 1989 to 2022 based on the keywords of Iran, non-syndromic, hearing loss, gene, mutation and pathogenic variants.

    Results

    So far, more than 130 genes causing non-syndromic hearing loss (NSHL) have been known in the world, of which 57 genes including 430 pathogenic and likely pathogenic mutations have been reported in NSHL patients in Iran. Based on the literature, GJB2, SLC26A4, MYO15A, MYO7A, CDH23, and TMC1 genes are among the most common causes of NSHL in Iran, respectively, and their distribution is different in various populations. In addition, missense mutation is the most common reported mutation.

    Conclusion

    This study while confirming the high genetic heterogeneity of NSHL in Iran, emphasizes the importance and revolutionary impact of next generation sequencing (NGS) techniques in diagnosing the genetic cause of hearing impairment in different populations of Iran. Such an approach can play a significant role in genetic counseling, prenatal diagnosis and clinical management of hearing impairment in affected families.

    Introduction

    The unique long-term challenges that families of children with hearing impairment experience put them at greater risk for increasing parental stress levels. This study seeks whether children’s hearing impairment affects their mothers’ emotional and coping styles with stressful situations.

    Materials and Methods

    The coping inventory for stressful situations and the maternal emotional styles questionnaire were distributed among 108 mothers of hearing-impaired children and an equal number of mothers of normal children.

    Results

    In the task-oriented, distraction, and social diversion styles, the mean scores of the mothers of healthy children were significantly higher than those of the mothers of hearing-impaired children. Regarding the emotion-oriented style, the mean score of the mothers of hearing-impaired children was significantly higher than that of the mothers of healthy children. With regard to the emotional coaching style, the mean score of the mothers of healthy children was significantly higher than that of the mothers of hearing-impaired children. There was no statistically significant difference between the two groups in the mean score of emotional dismissing.

    Conclusion

    It seems that mothers of hearing-impaired children use less effective coping and emotional styles that have adverse consequences for mothers and their children’s development.

    Background

    We aimed to investigate the demographic situation relating to people with hearing loss in Xinjiang, the largest province in China. The situation may vary between regions and races.

    Methods

    We conducted a population-based demographic study. We analyzed data obtained from 3931 people with hearing impairments (i.e., from the Han or Uyghur ethnic groups) including children and adults. We accounted for the survey design and sampling size in order to ensure that estimates were regionally representative. Basic characteristics were determined, and an ethnic distribution analysis was conducted based on age group, level of educational, marital status, and level of disability.

    Results

    Of the 3931 participants, 2228 (56.68%) were male and 1703 (43.32%) were female. The mean age of the participants was 46.02 (±19.46) years. Most of the participants (26.20%) were in the 45–59 yr age group. Illiterate people constituted the largest group (34.19%) in the Uyghur population, while a substantial proportion of participants of Han nationality had obtained a junior education (28.98%). The number of unmarried people in both ethnic groups accounted for the highest proportion (more than 70%). Grade 3 was the highest grade observed in the Uyghur population (32.35%), while Grade 1 hearing impairments were the most prevalent in the Han population (28.28%).

    Conclusion

    The difference in basic characteristics between participants of Uyghur and Han ethnicity revealed that different provinces should set different prevention and control targets. Different policy measures should be taken to allocate medical resources and provide rehabilitation services to assist people with hearing impairments in Xinjiang, China.

    Background & Objective

    Hearing impairment is a multidimensional disorder that causes personal and social problems. Children and adolescents with hearing impairment are more likely to be at risk than behavioral problems. Regarding the high prevalence of behavioral problems in children with hearing impairment, recognizing the behavioral characteristics, abilities, and issues of people with hearing impairment are important. Difficulties in expressive language and verbal processing are significantly associated with problems in executive functions. Some researchers have tried to justify relatively modest behavioral problems in children with hearing impairment with a defect in the growth of the theory of mind in these individuals. To study the effective factors causing behavioral problems in children with hearing impairment, we aimed to investigate the relationship between executive functions and theory of mind with behavioral problems in children with hearing impairment.

    Methods:

    The research method was descriptive correlational. The research community consisted of all elementary students in Tehran who were studying in deaf schools during the academic year of 2017–2018. According to Tabachnick and Fidell's formula, the sample size is estimated to be 84. This formula determines the minimum volume required for multiple regression studies. This study used 120 cluster randomized sampling to increase the external credibility and test power. We selected six schools randomly. Then, five classes were selected randomly from selected schools. Finally, four students with hearing impairment were selected in each school. The study data were collected using Stringenman's theory of mind test, Coolidge neurology questionnaire, and child behavioral inventory. The results were analyzed in SPSS software, using the Pearson correlation and multiple regression analysis systematically at a significance level of 0.05.

    Results:

     The results of this study showed significant negative relationships between planning and internalized behavioral problems (r=–0.22, p=0.014) and externalized behavioral problems (r=–0.33, p<0.001). There were significant reverse relationships between inhibition and internalized behavioral problems (r=–0.27, p=0.002) and externalized behavioral problems (r=–0.31, p<0.001). However, no significant relationships existed between the organization and internalized behavioral problems (r=0.14, p=0.112) and externalized behavioral problems (r=0.03, p=0.731). There were significant reverse relationships between the theory of mind and behavioral problems of externalization (r=–0.42, p<0.001) and internalization (r=–0.28, p<0.001). The theory of mind was the strongest predictor of internalized behavioral problems (β=–0.28, p=0.002) and externalized behavioral problems (β=–0.42, p<0.001) in children with hearing impairment.

    Conclusion

    Based on the study findings, executive functions and theory of mind play a major role in the behavioral problems of students with hearing impairment. Designing and implementing educational and therapeutic programs is essential to cultivate these factors.

    مقدمه

    یکی از مهم ترین عوارض مواجهه با نویزها، تغییرات الگوی بیان ژن های سیستم شنوایی می باشد. آسیب های برگشت ناپذیر گوش داخلی نظیر NIHL در اثر آسیب بافتی و تغییرات بیان ژن های سیستم شنوایی ایجاد می گردد. تغییرات الگوی بیان ژن GJB2، باعث بروز ناشنوایی اتوزومال در لوکوس های مختلف می شود. هدف از انجام این مطالعه، بررسی میزان بیان ژن GJB2 در بافت حلزون گوش مواجهه یافته با صدای سفید است.

    روش کار

    در این مطالعه تجربی، 10 سر رت ویستار به دو گروه مواجهه و یک گروه کنترل تقسیم بندی شدند. دو گروه آزمایش در معرض مواجهه با صدای سفید یکنواخت (حدود فرکانسی 20000-100 هرتز و مقدار تراز فشار صوت 120-118 دسی بل) قرار گرفتند. جهت مطالعات بافت شناسی و بیان ژن، پس از بافت برداری از حلزون گوش، به ترتیب آزمایشات بافت شناسی، استخراج RNA، سنتز cDNA و آنالیز qRT-PCR انجام گرفت.  

    یافته ها

    نتایج نشان داد که میزان بیان نسبی ژن GJB2 در گروه مواجهه W1 و گروهW2  به ترتیب 0/02 و 0/12 برابر نسبت به گروه کنترل کاهش معنی داری یافته بود (p-value<0.05). از طرفی نتایج مطالعه بافت شناسی نشان داد که بافت حلزون در گروه مواجهه W1 آسیب بیشتری نسبت به W2 دیده بود.

    نتیجه گیری

    کاهش معنادار این سطح از میزان بیان نسبی ژن GJB2 و آسیب بازگشت ناپذیر گانگلیون عصب شنوایی و غشای رایسنر، سبب تغییرات الگوی بیان این ژن در بافت حلزون گوش و تقویت بروز نقص شنوایی غیر سندرمی حسی-عصبی می گردد.

    Introduction

    One of the most important complications of exposure to noises is changes in the gene expression patterns. Irreversible damage to the inner ear, such as noise-induced hearing loss (NIHL), is caused by tissue damage and changes in the gene expressions in the auditory system. Changes in the GJB2 gene expression pattern lead to autosomal deafness at different loci. The present study aims to evaluate the GJB2 gene expression in cochlear tissue exposed to white noise.

    Material and Methods

    In this study, ten male Westar rats were divided into two experimental (W1, W2) groups of six rats and a control (normal) group of four rats. Two experimental groups were exposed to constant white noise in the frequency range of 100-20000 Hz and the sound pressure level of 118-120 dB. In order to study the histology and gene expression, after a cochlea biopsy, the histological tests, RNA extraction, cDNA synthesis, and qRT-PCR analysis were performed.

    Results

    The results showed that the transcript level of GJB2 was significantly decreased in both experimental groups W1 and W2 by 0.02 and 0.12-fold, respectively (p <0.05). Also, the results of the histological study showed that cochlear tissue was more seriously damaged in the W1 group than W2.

    Conclusion

    It can be concluded that a significant reduction in the GJB2 gene expression and irrevocable damage to auditory nerve ganglion and Reissner membrane (vestibular membrane) caused changes in the gene expression patterns in cochlear tissue and developed the risk of non-syndromic sensorineural hearing.

    315 نفر (169 نفر در گروه آزمایش و 146 نفر در گروه کنترل) در مطالعه شرکت کردند. میانگین± انحراف معیار غلظت هموگلوبین در گروه آزمایش و کنترل به ترتیب 1/36± 10/9 و 1/47± 12/67 بود. آستانه شنوایی در فرکانس های پایین و بالا در گروه کنترل نسبت به گروه شاهد بالاتر بود (به ترتیب 0/002=P و 0/032=P). رگرسیون لجستیک نشان داد شانس (Odds ratio] OR]) وجود پاسخ غیر طبیعی DPOAE در فرکانس 750 و 1000 هرتز در زنان مبتلا به کم خونی فقر آهن بیش از دو برابر افراد غیرمبتلاست (به ترتیب P=0/20 ، OR=2/40 ، P=0/006 ، OR=2/21).

    نتیجه گیری

    نتایج این مطالعه نشان داد که ارتباط معنی داری بین IDA و افزایش آستانه شنوایی هدایت استخوانی وجود دارد. به دلیل شیوع بالای IDA در زنان، این گروه ممکن است در معرض خطر بالاتری برای ابتلا به اختلالات شنوایی باشند.

    Background

     Iron Deficiency Anemia (IDA) is the most common form of anemia. Understanding the relationship between IDA and hearing loss may provide new insights into managing hearing loss.
    Objective This study aimed to investigate the relationship between IDA and hearing loss in women aged 12-45 years referred to Amir Al-Momenin and Al-Zahra hospitals in Rasht City, Iran.

    Methods

     In this case-control study, 315 women aged 12-45 years with IDA and without IDA were included. Study groups were matched by age. The amount of hemoglobin (based on the last blood test in the past month) of the subjects was measured and recorded. IDA was considered when the hemoglobin level was less than 12 mg/dL. Audiometry was performed for all participants.

    Results

     In total, 169 individuals in the case group and 146 individuals in the control group participated in the study. The mean±SD hemoglobin level in the case and control groups were 10.9±1.36 and 12.67±1.47 mg/dL, respectively. There were higher hearing thresholds in low and high frequencies among the case group than the controls (P=0.002 and P=0.032, respectively). Logistic regression analysis after age adjusting showed odds of abnormal Distortion Product Otoacoustic Emissions (DPOAE) in the frequencies of 750 Hz and 1000 Hz more than 2 times in women with IDA compared to controls (OR= 2.21, P= 0.006 and OR= 2.40, P= 0.020, respectively).

    Conclusion

     The study results showed a significant negative relationship between IDA and mean hearing threshold. Because of the high prevalence of IDA in women, this group may be at greater risk of hearing loss.

    Background

    Hearing loss may affect many aspects of a person's life. The age of cochlear implantation (CI) is often considered an important predictor of language skills of children with CI, but little is known about the benefits of early CI on speech intelligibility development in these children. This study aimed to compare language skills as well as intelligibility of speech in prelingual deaf patients who received CI before the age of six years and those who received CI after the age of six years with an 8-year follow-up.

    Materials and Methods

    This 8-year longitudinal, retrospective case–control study was conducted in 2021 at a cochlear implant center in Tehran, Iran. Thirty-one patients were included in two groups: late cochlear implant (n = 15), and early cochlear implant (n =16). The Test of Language Development- Primary (TOLD-P3) was used to assess the participants 'language skills. The intelligibility of the participants' speech was assessed through the Persian version of the Intelligibility Context Scale (ICS) and the speech intelligibility rating (SIR).

    Results

    These two groups did not show a significantly difference in terms of the language scores (P>0.05) but had a significantly difference in terms of the SIR and the ICS scores (P<0.05). Speech intelligibility had a significantly negative correlation with the age of CI (P<0.001), and had a significant positive correlation with language skills (P<0.001).

    Conclusion

    The long-term outcomes of early and late CI were similar in terms of the development of language skills but too different in terms of the intelligibility of speech. The age of CI had no effect on the language development but had a significant effect on speech intelligibility.

    اهداف

    در سال های اخیر استفاده از گوشی همراه افزایش یافته و بیش از 6/1 میلیارد مصرف کننده در سراسر جهان دارد. استفاده گسترده از گوشی همراه گمانه زنی در مورد خطرات احتمالی میدان های الکترومغناطیسی فرکانس بالا را بر سلامت افزایش داده است. گوشی های همراه تشعشعات میکروویو در محدوده فرکانس های هشتصد تا دو هزار مگاهرتز را دریافت و ارسال می کند و با توجه به نزدیکی گوشی های همراه به سر در مدت استفاده، دستگاه شنوایی و مغز بیش از بقیه بخش های بدن در معرض تشعشعات قرار دارند. مطالعه حاضر با هدف بررسی مطالعات انجام شده در این زمینه انجام شده است.

    مواد و روش ها

    با استفاده از پایگاه های اطلاعاتی وب آو ساینس، پابمد و گوگل اسکالر مطالعات مرتبط با موضوع جمع آوری و بررسی شد.

    یافته ها

    از میان 191 مقاله به دست آمده 48 مقاله مرتبط با موضوع مورد بررسی انتخاب و بر اساس مورد مطالعه (انسانی یا حیوانی) و مدت مواجهه (کوتاه مدت و بلندمدت) مرتب شدند.

    نتیجه گیری

    مطالعاتی که اثرات کوتاه مدت امواج الکترومغناطیس بر سلامت و دستگاه شنوایی را مورد پژوهش قرار داده اند، تاثیرات قابل توجهی را گزارش نکرده اند. با وجود این، در بیشتر مطالعاتی که اثرات طولانی مدت را بررسی کرده اند، تاثیرات چشمگیری مشاهده شده است. اجرای مطالعات بیشتر به جهت تعیین اینکه بعد از چه مدت زمانی از استفاده گوشی همراه تغییرات قابل اندازه گیری می شود، ضروری به نظر می رسد تا بتوان اقدامات لازم برای حفاظت از سلامت دستگاه شنوایی را انجام داد.

    Background and Aims

    Mobile phone use has increased in recent years and there is more than 1.6 billion users worldwide. This has increased speculations about the potential dangers of high-frequency Electromagnetic Fields (EMF) on health. Mobile phones receive and transmit microwave radiation in the frequency range of 800-2000 MHz, and due to the proximity of mobile phones to the head during use, the hearing system and brain are more exposed to radiation compared to other parts of the body. The present study aims to review the studies conducted on examining the effect of EMF from mobile phones on the hearing system.

    Methods

    In this narrative review study, the search was conducted in Google Scholar, PubMed, and Web of Science databases on the related studies.

    Results

    The studies investigating the short-term effects of EMF on the health of auditory system did not report significant effects, but most of those conducted on its long-term effects showed significant effects.

    Conclusion

    Further studies are needed to determine how long after the use of mobile phones the effects can be measured so that the necessary measures can be taken to protect the health of the hearing system.

    Background

    More than 6.8% of the world's population suffer from disabling hearing impairment. Hearing impairment can cause lifelong or even life-threatening problems and has a significant impact on the health and quality of life. This study aimed to analyze the current situation of the ear and hearing care (EHC) in the frame of Iran health system.

    Methods

    This situation analysis was performed over a 5-year period (2013-2017) using the Strengths, Weaknesses, Opportunities, and Threats analysis method. First, after formation of the steering committee, all relevant published and unpublished articles and reports were reviewed and analyzed. In the next step, focused group discussion sessions (FGDs) were held with the participation of the experts, stakeholders, and Steering Committee members. Through the scissor-and-sort technique, the relevant data were highlighted and main categories evolved.

    Results

    The main challenges included inadequate health literacy, weak intrasectoral and intersectoral cooperation, the inadequacy of policy responses, nonintegration of the EHC in the primary health care system, poor standard processes, and resources of EHC, and lack of EHC surveillance system. The 6 major interventions and strategies extracted as identifying the capacities of both the public and private sectors, reinforcement of intersectoral cooperation and intersectoral collaboration, standardizing the processes and integrating of EHC services in the PHC, reorganizing the referral system, promoting hearing health literacy, and minimizing hearing loss risk factors.

    Conclusion

    Implementing the proposed interventions and strategies is essential to improve the situation of Iran EHC management system during the next 5 years.

    Background

    Mother-child interaction and spiritual well-being can influence child behavioral disorders by affecting the mother’s mental health. The present study was done to investigate the relationship between mother-child interaction and spiritual well-being and child behavioral disorders with the mediation of mental health in mothers of children with hearing impairment.

    Methods

    The descriptive correlational study used a path analysis. The statistical population included 1580 mothers of children with hearing impairment in Tehran in 2019. The sample size was determined using Morgan’s sample size table. The samples were selected based on stratified random sampling. To collect the required data, 310 questionnaires based on the research variables were provided to the participants and a total of 284 questionnaires were analyzed following the elimination of incomplete questionnaires. The research instruments included the Behavior Disorders Questionnaire, the Child-Parent Interaction Questionnaire, the Spiritual Well-being Questionnaire, and the Mental Health Questionnaire. The proposed model was evaluated using path analysis by AMOS v. 24 software.

    Results

    The results showed that there was a significant relationship between spiritual well-being and child behavioral disorders (P<0.01), mental health and child behavioral disorders (P<0.01), child-mother interaction and mental health (P<0.01), and spiritual well-being and mental health (P<0.01), but there was no a significant relationship between child-mother interaction and child behavioral disorders (P>0.05). Moreover, indirect paths of child-mother interaction and child behavioral disorders with a mediating role of mental health (P<0.01) and spiritual well-being and child behavioral disorders with a mediating role of mental health were significant (P<0.05).

    Conclusion

    According to the results of this study, the proposed model had a good fit, and is an important step in identifying the factors affecting the child behavioral disorders of children with hearing impairment.

    Aims

    MusculoSkeletal Disorders (MSDs) are one of the most common problems of students which if not prevented and treated can lead to physical and psychosocial disorders.The aim of this study was to compare MSDs in two groups of students with special needs who suffering from low vision and hearing impairment.

    Method and Materials

    A cross-sectional study was conducted with of 62 students aged between 10-15 years old in Hamadan in 2019-2020 . Of these participants, 32 students living with hearing impairment and 30 students living with low visions. Demographic questionnaires and Nordic musculoskeletal disorders were used to collect data. SPSS software version 23 was used to analyse data through two-sample independent t-test,  chi- square test and logestic regression.

    Finding

    Tottaly 62 students took part in the study. The mean age of Low Vision Students( LVS) and Hearing Impairment Students (HIS) was 12.101.47± and 12.47± 1.64 years respectively. Of all students with low vision 10 individual (33.3%) and of all students with hearing impaiement 10 individuals (31.3%)  were suffering from MSDs. The most MSD affected areas in HIS was lumbar (15.6%) and in LVS was shoulder (16.7%). The results showed that MSDs did not differ significantly between the two groups of LVS and HIS (P> 0.05).

    Conclusion

    This study showed that at least one-third of LVS and HIS suffered from MSDs.   The need for therapeutic and educational strategies in the field of ergonomics interventional program for health promoting  of these students with special needs should be considered.

    Background 

    Pragmatic skills of language are important for everyday life interactions. It has been proven that cochlear implantation age should be considered, as an important predictor of language skills in children with cochlear implantation (CI), but information about the benefits of early cochlear implantation on pragmatic language development in these children are very few. Thus, this study intends to compare pragmatic skills as well as speech intelligibility in prelingual deaf children who received cochlear implants before the age of 6 years and those who received cochlear implants after the age of 6 years with an 8-year follow-up.

    Materials and Methods

    This Retrospective 8-year longitudinal study was conducted in a cochlear implant center in the city of Tehran, Iran, in 2021. Forty-five children were included in two groups: early cochlear implant (n = 17), and early cochlear implant (n = 28). The Persian version of the children's communication checklist (CCC) was used to assess the participants 'pragmatic skills and the Persian version of the Intelligibility Context Scale (ICS) was used to assess the participants' speech intelligibility.

    Results

    The two study groups did not show a significant difference in terms of pragmatic scores (P>0.05) but had a significant difference in terms of ISC scores (p <0.001). Speech intelligibility had a significant negative relationship with the age of cochlear implantation (r = -0.5, p <0.001) but had no significant correlation with pragmatic skills (P>0.05).

    Conclusion 

    The long-term results of early and late cochlear implants were similar in terms of the development of pragmatic skills but very different in terms of speech intelligibility. The age of cochlear implantation had no effect on the pragmatic of language.

    Background

      Sensory processing is an important factor in development and affects the function of the senses in daily living activities. Hearing impairment may lead to some difficulties in sensory processing in children with hearing impairment.

    Objectives

      In this cross-sectional study, the sensory processing of children with hearing impairment and that of their normal hearing peers who were between 3 to 6 years old were compared.

    Methods

    The study population consisted of 60 normal-hearing and hearing-impaired children with hearing aids in Shiraz who were between 3 and 6 years of age. Dunn’s Short Sensory Profile was utilized in both groups. The results were statistically analyzed by SPSS 21, and a p-level of < 0.05 was considered significant.

    Results

    Independent t-test results showed that there was no significant difference between the two groups in total sensory processing (p-value = 0.097), touch sensitivity (p-value = 0.043), olfactory and taste sensitivity (p-value = 0.259), movement sensitivity (p-value = 0.079), sensory seeking (p-value = 0.229), hearing processing (p-value = 0.390), low energy and weakness (p-value = 0.916), or hearing and vision sensitivity (p-value = 0.429). The total mean score was 15.28 ± 4.8 for children with hearing aids and 15.28 ± 4.6 for normal-hearing children.

    Conclusions

    The results of this study showed that the impact of hearing impairment on sensory processing is unperceivable and needs to be addressed through more research However, it does seem that hearing impairment may affect one area of sensory processing.

    Background and Aim

    Expressive language is the most basic and widespread means of communication; children with hearing impairments are one of the largest groups of children with speech and language disorders. Therefore, this study compares the relationship between the development of expressive language and social skills in children with cochlear implants (CIs), hearing aid (HA) users and normal Persian-speaking peers aged five to seven years old.

    Methods

    The present study is a cross-sectional comparative study. 45 children in three groups; normal hearing, CIs and HA users were selected by convenience sampling. The child’s communication and social skills were assessed using Matson and children’s communication checklist (CCC) tests. Through the analysis of a descriptive speech sample of language indicators, the mean length of utterance- morpheme (MLU-m), number of different words (NDW) and the percentage of intelligible utterances (PIU) of the child were obtained and examined. ANOVA test was used to compare the groups and Pearson test was used to examine the correlation between variables.

    Results

    The mean score of CCC test, PIU and NDW are significantly different in the three groups. MLU and Matson subtests are not significantly different in three groups. Correlation between variables was different in each group.

    Conclusion

    Communication skills, intelligibility, and lexical diversity are significantly different between normal and hearing- impaired children. MLU and Matson subtests are not significantly different in three groups. The correlation patterns among different subtests of CCC and Matson for children with hearing impairment were different form normal hearing children.
