Heari ng represents the main source for acquisition of language and speaking skills in childhood. In the first months of life, the hearing impaired child is deprived of sound stimulation in the most important period of development, and consequently, might present emotional, social and linguistic disorders. Therefore, it is of utmost relevance to learn about the main etiological factors that cause the auditory damage to trace a reliable nosological profile, and to take the appropriate measures to prevent and guide the family on the repercussions of hearing impairment in childhood. Aim: To characterize the etiology profile of hearing impairment in a reference center for hearing impaired children and adolescents. Methodology: We performed interviews, speech and hearing screening and analyses of medical charts of 87 hearing impaired children that were part of Associação de Pais e Amigos dos Deficientes Auditivos do Estado da Bahia (APADA-BA), trying to define etiology, gender distribution, age at diagnosis, level of hearing loss, age at hearing aid fitting, and rehabilitation. Results: Among the 87 children and adolescents who had undergone speech and hearing screening, we select a sample of 53 subjects, whose parents had come for three sessions of anamnesis and assessment. The main responsible etiological factor for hearing loss in the evaluated population was maternal rubella, amounting to 32% of the cases of deafness, followed by pyogenic meningitis with 20%, idiopathic cause with 15%, prematurity with 9%, heredity (deaf father or mother) and neonatal jaundice, which also presented 6% incidence; chronic otitis media represented 4%, use of misoprostol in the gestation, measles, ototoxicity and mumps, each factor with 2%. Conclusion: The present study demonstrated the heterogeneity of factors that cause hearing impairment, and the two main causes (rubella and pyogenic meningitis) still present high incidence in the studied population. We believe that preventive measures must be taken, especially in the prophylaxis of maternal rubella and extended vaccination of neonates and infants against bacterial meningitis.
Bacterial meningitis is still a major public health threat inside developing countries. In Brazil, the Department of Public Health estimates that the prevalence of bacterial meningitis is 22 cases per 100,000 persons. During the neonatal period, the bacterial meningitis develops special characteristics that can result in hearing problems and movement loss due to neurological and psychological damages. This study had the aim to analyze the prevalence of bacterial meningitis and sepsis in newborns during the pregnancy period for those using the public health care system in Salvador-Bahia. One of the goal was to describe the risk factors of bacterial meningitis and sepsis in newborns. A second goal was to identify, based on newborn health records, the difficulties to predict issues with the hearing, neurological and psychological problems. This study has a cross-sectional design. The newborns that were included in this study had bacterial meningitis or sepsis within 0-28 days of life. They were admitted in the maternity wards between June-December 2005 at the newborn intensive unit care. We analyzed 72 reports of newborns and only 11 (17%) were bacterial meningitis or sepsis newborn cases. These cases were associated to high intake of ototoxic drugs that can cause oto and nephrotoxicity, and cause serious sequels on the child development. Nervous system infection is one of the 2 major problems in clinical practice, especially during the first month after birth. During this first month, the nervous system infection develops special characteristics, which are different from regular symptoms and it requires treatment due to the increased risk to develop complications. It is strongly recommended to monitor ototoxic drugs use to prevent effects on the hearing system. Key-Words: Newborn meningitis, sepsis, prevalence, prediction, complications.The neonatal meningitis is an illness characterized as a result of infection and inflammation of the meninges and it typically happens between birth and the first 28 days of life [1].The bacterial infection is more common during the first month after birth compared to other stages of newborns. It has an incidence that varies from 0.22 to 2.66/1,000 newborns in different countries and it tends to be more common in developing countries [2].During the neonatal period, the illness has special characteristics. The etiology, the clinical symptoms and the mortality appear to be different from the observed in older children [3].The mortality varies based on the treatment, with survival rates of 17% to 29% and with complications rate of 15% to 68%. Among the predictive factors for determining the diagnosis of this condition are the premature birth, newborn weight, type of bacteria, predisposition for the microbial germ, the length of the treatment and complications [4].Although there have been medical advances of medicines and preventive medicine, the incidence of newborn bacterial meningitis for the last 30 years has been barely affected. This minor change in the incidence can be linked po...
OBJETIVO: Analisar a prevalência de déficit auditivo e caracterizar as principais sequelas auditivas e neurológicas pós-meningite, correlacionando o tipo de antibiótico utilizado durante o período de internação e a frequência de surdez, além do tipo de meningite mais prevalente como causa de déficit auditivo. MÉTODOS: Trata-se de um estudo de coorte transversal. Foram enviadas 289 cartas para os responsáveis pelas crianças que apresentaram meningite piogênica entre 28 dias e 24 meses, admitidas no Hospital Couto Maia (HC Maia) entre janeiro de 2002 a dezembro de 2003. A amostra foi constituída por 55 crianças que sobreviveram com ou sem sequelas evidentes, que compareceram para as avaliações audiológica e neurológica. Foi realizada avaliação audiológica completa, incluindo a bateria subjetiva e objetiva de avaliação, com utilização de instrumentos validados para investigação da audição da criança. RESULTADOS: A faixa etária, no momento da avaliação audiológica, variou de dois a cinco anos. A deficiência auditiva foi encontrada em 29% da amostra, sendo a maioria do tipo neurossensorial, bilateral e de grau profundo. As principais sequelas neurológicas encontradas foram epilepsia, hemiparesia, hidrocefalia, disfasia e hiperatividade. CONCLUSÃO: Os resultados destacam a necessidade de monitoramento audiológico e acompanhamento neurológico nas crianças com história prévia de meningite piogênica, especialmente aquelas infectadas em idade precoce, buscando, desta forma, detectar as possíveis alterações auditivas e intervir o mais precocemente possível, por meio de intervenção especializada, protetização e reabilitação da linguagem oral.
