“…The mean age of babies in the out-patient department is consistent with the mean age of 47 days for screening infants at mother-child clinics who were missed by hospital-based screening [30] but reflects the increased difficulty of screening babies once they have been discharged until the sixth week post-natal visit. This is typical with mothers in our study who insisted on being discharged on days when screening was not being undertaken such as on public holidays.…”

“…The incidence of PCEHL of 5.3 per 1000 for all categories of permanent hearing loss (30 dB nHL) based on the total enrolment for this study is comparable to the 5.2 in Taiwan [37], 5.6 in Hong Kong [25] and India [38] but lower than the 7.9 in Pakistan [31], 11.4 in Jordan [30], 12.0 in Oman [28]. These rates seem to justify the current global estimate of at least 6 per 1000 previously postulated for developing countries [39], in contrast to the 2-4 per 1000 estimated for developed countries [40].…”

“…18,34,35 NNJ is the most common condition requiring evaluation and hospital admission in the first week of life 36 and constitutes a significant cause of neonatal mortality and morbidity. 37 Although icterus neonatorum at serum levels not exceeding 5-6 mg/dl (86-103mmol/l) is a benign transitional phenomenon in the vast majority of neonates, excessive unconjugated bilirubin may lead to kernicterus and sensorineural hearing loss.…”

Objective The objective of this study was to determine the role of non-hospital delivery and other risk factors for permanent congenital and early-onset hearing loss (PCEHL) in a developing country. Design Matched case-control study. Setting Four primary healthcare centres in inner-city Lagos, Nigeria. Population Fifty-six infants with PCEHL and 280 normal hearing controls matched for age and sex from a population of infants not older than 3 months attending Bacille de Calmette-Guérin immunisation clinics. Methods Conditional logistic regression analyses of infant and maternal characteristics associated with PCEHL, and the evaluation of population exposure to each risk factor. Main outcome measures Adjusted matched odds ratios and population attributable risk percent (PAR%). Results Children with PCEHL were significantly more likely to be first born (OR 1.9, 95% CI 1.1-3.6) without skilled attendants at birth (OR 2.4, 95% CI 1.3-4.5) and have a history of neonatal jaundice requiring exchange blood transfusion (NNJ/EBT) (OR 9.6, 95% CI 2.4-38.2) but less likely to be small for gestational age (SGA) (OR 0.1, 95% CI 0.0-0.5). After controlling for other covariates, the absence of skilled attendants at birth (OR 4.2, 95% CI 2.0-8.6) and NNJ/EBT (OR 19.1, 95% CI 4.3-85.5) emerged as predictors of PCEHL, while SGA (OR 0.1, 95% CI 0.0-0.2) retained its inverse relationship with PCEHL. The PAR% was 35.9% for the lack of skilled attendants at birth and 10.6% for having NNJ/EBT. About 23% of children with PCEHL did not exhibit any risk factors. Conclusions NNJ/EBT and the absence of skilled attendant at birth rather than the place of delivery are significant predictors of PCEHL in this study population. Targeted hearing screening using these risk factors would facilitate the detection of about 77% of children with PCEHL.

This study describes 5 infants who were diagnosed with auditory neuropathy (AN) associated with severe to profound neural hearing loss shortly after birth. However, on repetition of the tests 7–12 months later, all infants showed full or partial recovery. The follow-up electrophysiological patterns were characterized by the appearance of wave I, followed by wave III and V, reflecting synchronization of auditory pathways and improvement in auditory nerve function. Suspected causative or contributory factors were neonatal hyperbilirubinemia, hypoxia, ischemia, and central nervous system immaturity, alone or in combination. These findings indicate that lack of an auditory brain stem response does not necessarily mean no hearing and that the situation where AN exists can improve. Thus, clinicians should be made aware that although cochlear implants may yield better auditory performance when applied early, they should be considered a therapeutic option only after repeated measures have proved persistent AN, and no child should be considered for an implant until a behavioral measure of hearing has been obtained.
