Transient-evoked otoacoustic emission findings in children (1-12 years) with cerebral palsy in Kano, Nigeria.

BACKGROUND: Children with cerebral palsy (CP) suffer from multiple problems and potential disabilities. These range from musculoskeletal problems, mental retardation, epilepsy, ophthalmologic and hearing impairment among others. Consequences of hearing loss include problems with speech and language development. Early detection in this difficult-to-test population may prevent these consequences of hearing loss. An otoacoustic emission assessment is useful in this regard. This study assessed transient-evoked otoacoustic emissions (TEOAEs) in children with CP. MATERIALS AND METHODS: The study population were children with CP who presented at the paediatric neurology clinic during the study period. An equal number of control population matched for age and sex were also recruited using simple random sampling. An interviewer-administered questionnaire was used to obtain relevant clinical information. All participants selected underwent a detailed ear, nose and throat examination and TEOAE testing. RESULTS: There were 330 participants in this study, categorised into CP cases (165) and non-CP controls (165). The age range of the participants was 1-12 years, with a mean age of 4.44 ± 2.92 among CP patients and 4.47 ± 2.90 among the controls. The male-to-female ratio was 2:1. TEOAEs were 'failed' in 83.6% of the CP patients and in 28.5% of the controls. This study found a statistically significant difference in 'failed' TEOAE result between the CP patients and the controls (P = 0.0001). CONCLUSION: This study found a high prevalence of 'failed' TEOAEs in children with CP in Kano.

Factors Influencing Neonatal Practice in a Rural Community in Kano (Northern), Nigeria.

Nigeria has the highest number of neonatal and under-five deaths in Africa. Socio-cultural determinants play an important role in disease burden in low-middle income countries. This study aimed to describe knowledge, attitudes and neonatal care practice among household caregivers in a rural community in Nigeria, specifically uvulectomy, female genital mutilation (FGM), failure to routinely immunize and unsafe cord care. Further, relationships between demographic characteristics and knowledge, attitudes and neonatal care practices among caregivers were analyzed. The study design was descriptive correlational and cross-sectional. Consented caregivers (N = 298) were enrolled and interviewed using a structured questionnaire. Data were collected on demographic characteristics of the study participants and practice of uvulectomy, FGM, immunization and cord care. Statistically significant correlations were found between the practice of uvulectomy, FGM and failure to immunize based on occupation (p = 0.0202, p = 0.0290, p = 0.0071) and educational level (p =< 0.0001, p =< 0.0001, p =< 0.0001), with variations by ethnicity. Intense, preventative health measures and maternal education to eliminate harmful care practices are essential to influence outcomes.

Follow-up of Children with Kernicterus in Kano, Nigeria.

INTRODUCTION: Acute bilirubin encephalopathy (ABE) is associated with long-term sequelae (kernicterus). It continues to be a significant issue in our region of Nigeria, accounting for much morbidity and mortality. Herein we report the outcome of neonates with ABE seen at our centre. METHODOLOGY: We established a surveillance of children who had ABE and returned to follow-up from prospective cases of ABE (2012-2014). ABE was diagnosed based on a bilirubin-induced neurologic dysfunction score of ≥ 1. Kernicterus was subsequently established based on a history of developmental delays, hearing impairments and abnormal physical and neurologic examinations at follow-up age ≥3 months. RESULT: Five hundred fifty-one neonates had hyperbilirubinaemia of whom 104 (18.8%) had ABE. Mean transcutaneous bilirubin using the Ingram icterometer was 18.3 mg/dl ± SD 1.9 [(12.5-19.1), total serum bilirubin of 18.1 ± 10.9] (range: 10.3-64 mg/dl). Sixty-five infants returned for follow-up (41 males and 24 females); mean age 9 months (22 days to 17 months). Most (58 of 65; 89.2%) had abnormal neurological findings and 15 (25.9%) had probable kernicterus. CONCLUSION: There is a critical need for a National Kernicterus Registry to document all cases of kernicterus and formulate an effective treatment and prevention policy.
