A Hearing Screening Program for Children in Primary Schools in Tajikistan: A Telemedicine Model

Ophthalmic screening was done on 23,810 children visited at schools in different regions of Ankara. Children with below normal visual acuity were invited to the outpatient department and had a full routine ocular examination. Thirty-nine nursery and primary schools were selected, ten of them private, eleven average state schools, seven good state schools and eleven village schools. Among the 23,810 children, 3095 (13%) had various pathology; 1516 were girls, 1579 boys. Refractive errors were found in 85% of the children (2630). This equals 11% of the total screened population. Refractive errors were myopia 32%, hypermetropia 21%, astigmatism 47%. Strabismic children were 2.5%, and amblyopia was found in 1.1%. The purpose of the study was to assess the place of an ocular screening program in primary school children and to discuss the differences encountered in different urban areas.

Reduction of hearing is the most common sensory impairment among newborns with an incidence of 1-3 per 1000 births. Introduction of an Auditory Newborn screening program allows early identification of hearing impairment. Mainly, congenital hearing loss in early childhood is a result of genetic changes. Due to high frequency of GJB2 pathogenic variants, its molecular characterization among sensorineural hearing reduction cases is already conducted as a routine analysis in many countries. The aim of this study is to show our initial results in the effort to determine whether genetic screening along with the standard hearing screening in newborns is justified. Otoacoustic emission (OAE) method was conducted in 223 newborns at risk of hearing impairment. Among them, 7 did not pass the test in both ears while 9 exhibited one-sided hearing loss. In all 7 children with indication of profound bilateral deafness, the diagnosis was confirmed using auditory brainstem response. Genetic screening of GJB2 gene was performed in 6 of them. Genetic analysis of GJB2 revealed homozygous state of the most common pathogenic variant 35delG in 3 (50%) of the analyzed infants. In the remaining 3 no pathogenic variant was determined. The results indicate that performing auditory OAE together with genetic screening is justified. In newborns who have not passed the hearing screening test and have profound hearing loss, without other syndrome traits, screening for mutations of GJB2 gene should be conducted. Genetic screening enables establishment of early definite diagnosis for deafness and helps in conducting adequate therapy providing timely rehabilitation and social inclusion of deaf child.

Newborn Hearing

Introduction: Hearing loss is one of the most common congenital disorders. The prevalence of this disorder in different communities has been reported between 3.5 to 9 percent, which can have adverse effects on language learning, communication, and education of children. Also, early diagnosis of this disorder in newborns is not possible without the use of hearing screening. Therefore, the aim of this study was to evaluate the effectiveness of newborn hearing screening programs in Zahedan. Method: In this cross-sectional observational study, all babies born in the maternity hospitals of Zahedan city (maternity hospitals of Nabi Akram, Imam Ali, and Social Security hospitals) in 2020, were examined. In order to conduct the study, TEOAE was initially performed for all neonates. Then, based on the results obtained in the ODA test and in case of unsatisfactory response, cases were referred for re-evaluation. Infants who were rejected again in the second stage were immediately subjected to the AABR test and if they failed in this test, they were also subjected to a diagnostic ABR test. Results: Based on our results, 7700 infants were first evaluated with the OAE test. Of these, 580 (8%) had no OAE response. Out of 580 infants rejected in the first stage, 76 infants were also rejected in the second stage; Among them, 8 infants were re-diagnosed with hearing impairments. Finally, out of 3 infants who were diagnosed with hearing loss, 1 (33%) had conductive hearing loss and 2 (67%) had sensorineural hearing loss. Conclusion: Based on the findings of the present study, the implementation of a comprehensive neonatal hearing screening program is necessary for the timely and early diagnosis and treatment of hearing loss. Also, screening can improve the health of children and their personal, social, and educational development in the future. Keywords: Hearing screening, hearing loss, newborns, OAE, AABR
