Objectives: To find out the incidence of hearing impairment in Neonatal Intensive Care Unit (NICU)-admitted newborns and to correlate between several risk factors. Design: Prospective observational study. Setting: In a tertiary teaching hospital of Odisha between October 2014 and October 2016. Study population: 100 newborns delivered in the institution and admitted in NICU with usual indications and risk factors that underwent otoacoustic emission 1 and 2 (OAE1, OAE2) and Brainstem Evoked Response Audiometry (BERA). Results: 84 babies in OAE1 and 86 babies in OAE2 got “pass” results. In BERA test, 92 babies got normal waveform. 7 (13.7%) of 51 premature babies, 5 (38.5%) of 13 very low birth weight babies, 7 (17.5%) of 40 babies receiving ototoxic medication for >5 days, 7 (31.8%) of 22 babies with hyperbilirubinemia, 6 (42.9%) of 14 babies with sepsis, 5 (20%) of 20 babies with birth asphyxia, 3 (60%) of 5 babies under mechanical ventilation for >5 days, 1 baby with ear abnormality, and 1 (50%) out of 2 babies with congenital infections had hearing impairment and statistically significant association with abnormal OAE and BERA test. Conclusion: There is high incidence of hearing loss in NICU-admitted newborns. OAE and BERA both should be performed for complete evaluation of hearing. Important risk factors are elaborated. Predischarge hearing assessment in NICU is most important.

<p class="abstract"><strong>Background:</strong> Hearing impairment is a common disability in children. This study is to evaluate the common high risk factors for hearing loss in our locality and to estimate hearing threshold by brain stem evoked response audiometry.</p><p class="abstract"><strong>Methods:</strong> 100 children under five years were subjected to brainstem evoked response audiometry. Wave V morphology was studied and hearing threshold estimated. The high risk factor(s) were analysed and degree of hearing impairment assessed.  </p><p class="abstract"><strong>Results:</strong> 38 children were found to have hearing impairment. Most of the children had bilateral hearing impairment. Of them 30 children (79%) had profound hearing loss. Consanguineous marriage was the most common risk factor.</p><p class="abstract"><strong>Conclusions:</strong> Since consanguinity is the most common risk factor, health education and genetic counselling will help to decrease the incidence of autosomal recessive nonsyndromic deafness. Improvement in immunization for rubella can decrease the hearing impairment due to these infections. Due to availability of medical facilities hearing impairment due to perinatal factors have decreased.</p>

Background: A child’s normal speech and language development depends on the ability to hear. Early detection of hearing loss by screening at or shortly after birth and appropriate intervention are critical to speech, language and cognitive development. Objectives were to describe socio-epidemiological profile of newborns for hearing loss screening by transient evoked oto-acoustic emissions (TEOAE) and brainstem evoked response audiometry (BERA) in Rajendra Institute of Medical Sciences (RIMS), Ranchi, Jharkhand, India during 18 months period (June 2015- November 2016), and to study association between hearing loss and risk factors.Methods: This prospective study was done on 4356 newborns for hearing screening by TEOAE in maternity ward and NICU and BERA in those noted “refer” on retest TEOAE at RIMS, Ranchi, Jharkhand, India during the period of 18 months (June 2015 - November 2016). Follow- up done by visits and phone calls. Templates were generated in MS excel sheet and data analysis was done using SPSS software (version 20).Results: Study showed 3.90/1000 newborns were noted “refer” on retest TEOAE. Hearing loss (BERA- Fail) is slightly more common in males (2.20/1000 newborns), of rural areas (2.44/1000 newborns), tribal ethnicity (2.75/1000  newborns) and those delivered by lower section caesarean section (LSCS) (4.47/1000 newborns). Hearing loss noted in 2.07/1000 newborns. Among high risk newborns 21.41/1000 newborns were noted “refer” on retest TEOAE and 11.53 were found BERA fail.Conclusions: Hearing loss was 21.71 times more common in newborns associated with high risk factors, mainly low birth weight and preterm newborns.

Introduction: Brainstem Evoked Response Audiometry (BERA) is an auditory electrophysiological examination to objectively and non-invasively assess the integrity of the central auditory system. BERA examination is proposed to be carried out on every newborn as a standard examination to identify early hearing loss in newborns. The incidence of congenital deafness between 4-6 babies in 1000 live births in developing countries. Purpose: This study aimed to determine the characteristics of patients undergoing BERA examination including age, gender, hearing threshold values, risk factors, and the spread of events in the Central Java region. Methods: This was a retrospective descriptive study utilizing medical records of patients undergoing BERA examination conducted at the hospital. Dr. Kariadi Semarang from January 2016 - December 2016. There were 515 patients who underwent BERA examination from 35 districts and cities in Central Java. Most patients undergoing BERA examination came from the city of Semarang. Results: Most patients underwent BERA examination aged 0-3 years, with the most frequent risk factors being febrile seizures and profound was found to be the highest results. Discussion: The incidence of hearing loss in children 0-3 years with a hearing threshold of more than 86 dB was the highest incidence in Semarang within 2016. Conclusion: BERA examination has not been able to reach other areas around Central Java.
