Araújo, Eliene da Silva;Zucki, Fernanda;Corteletti, Lilian Cássia Bórnia Jacob;Lopes, Andrea Cintra;Feniman, Mariza Ribeiro;Alvarenga, Kátia de Freitas;
Jornal da Sociedade Brasileira de Fonoaudiologia , 2012, DOI: 10.1590/S2179-64912012000200017
Abstract: purpose: to investigate the occurrence of hearing loss in individuals with hiv/aids and their characterization regarding type and degree. research strategy: it was conducted a systematic review of the literature found on the electronic databases pubmed, embase, adolec, ibecs, web of science, scopus, lilacs and scielo. selection criteria: the search strategy was directed by a specific question: "is hearing loss part of the framework of hiv/aids manifestations?", and the selection criteria of the studies involved coherence with the proposed theme, evidence levels 1, 2 or 3, and language (portuguese, english and spanish). data analysis: we found 698 studies. after an analysis of the title and abstract, 91 were selected for full reading. out of these, 38 met the proposed criteria and were included on the review. results: the studies reported presence of conductive, sensorineural, and mixed hearing loss, of variable degrees and audiometric configurations, in addition to tinnitus and vestibular disorders. the etiology can be attributed to opportunistic infections, ototoxic drugs or to the action of virus itself. the auditory evoked potentials have been used as markers of neurological alterations, even in patients with normal hearing. conclusion: hiv/aids patients may present hearing loss. thus, programs for prevention and treatment of aids must involve actions aimed at auditory health.

Abstract: OBJETIVO: verificar a ocorrência de perda auditiva sensorioneural em crian as com baixo nível de exposi o cumulativa ao chumbo. MéTODO: 156 crian as intoxicadas por chumbo, 94 do sexo masculino e 62 do sexo feminino, na faixa etária entre 18 meses a 14 anos e 5 meses, foram submetidas a análise longitudinal do nível de Plumbemia em sangue, bem como audiometria tonal liminar e emiss es otoacústicas evocadas por estímulo transiente. RESULTADOS: a popula o pesquisada apresentou um valor médio de Plumbemia estimada de 12,2±5,7mg/dL (faixa entre 2,4-33mg/dL); todas as crian as apresentaram resposta normal na audiometria tonal liminar em 20 dBNA nas frequências testadas, 0,5; 1; 2 e 4 kHz, para ambas as orelhas; as emiss es otoacústicas evocadas por estímulo transiente estiveram presentes para todas as frequências bilateralmente, nas 79 crian as pesquisadas. CONCLUS O: n o foi constatada perda auditiva sensorioneural em crian as com histórico de baixo nível de exposi o cumulativa por chumbo, assim como n o foi encontrada les o de células ciliadas externas na cóclea, mesmo que subclínicas. PURPOSE: to verify the occurrence of sensorineural hearing loss in children with low level of cumulative lead exposure. METHOD: 156 lead-poisoned children, 94 males and 62 females, ranging in age from 18 months old to 14 years and 5 months old were subjected to analysis of longitudinal lead level in blood as well as pure tone audiometry and transient evoked otoacoustic emissions. RESULTS: the population studied had a mean estimated blood lead level of 12,2±5,7mg/dL (range between 2,4 and 33mg/dL); all children had a normal response in pure tone audiometry at 20 dBHL in the frequencies tested, 0.5, 1, 2 and 4 kHz, in both ears; the transient evoked otoacoustic emissions were presented for all frequencies bilaterally in 79 children surveyed. CONCLUSION: there has been no hearing loss in children with a history of low cumulative lead exposure, as there was no injury of cochlear outer hair cells, even if subclinical.

Abstract: purpose: to check the practice of newborn hearing screening in curitiba-pr. methods: a survey was initially conducted to check the number of existing maternities and hospitals with maternities included in the national register of health's establishments. we found that 59 hospitals were registered; three are maternities and 18 are hospitals that include a maternity. we asked each of the professionals in charge for the institution if some kind of newborn hearing screening was conducted and, for those who had the service, a questionnaire was given in order to collect information on the program. results: we found that 23.8% of the institutions perform newborn hearing screening. in 20% of them, this service is universal for full term babies, while in 80% of them it is available for premature/high risk babies. all of the services use transient evoked otoacoustic emissions (teoae). conclusion: we concluded that the brazilian law number 14588 - 22/12/2004 is not being followed. despite of the need and the importance for early detection of hearing loss, hearing screening is not accomplished in all maternities. in places where such screening takes place, it is not universal.
Os efeitos da exposi??o ocupacional ao chumbo sobre o sistema auditivo: uma revis?o da literatura
Jacob, Lilian Cássia Bornia;Alvarenga, Kátia de Freitas;Morata, Thais Catalani;

Abstract: despite the fact that the term occupational hearing loss is usually associated with noise-induced hearing loss, the scientific literature indicates that there are other work-related agents that can be damaging to the worker's auditory health. lead is considered as one of these agents, and several researchers have investigated its effects on the auditory system. there are numerous studies on the effects from lead intoxication to the body, which demonstrate that multiple organs can be affected. however, investigations of the auditory effects of lead are scarce, and offer conflicting results. studies that take into consideration the combined exposure to lead and other agents, as noise, are practically unexistent. the industrial uses of this metal are extensive and usually the work conditions in a large number of brazilian industries expose the worker to high lead concentrations. the studies reviewed in the present paper indicate that the consequences of lead exposure to the peripheral and central auditory system are not yet fully understood. moreover, due to the seriousness of the potential risk, they underscore the need for further research on the effects of more than one agent to workers' hearing health.

Revista Brasileira de Otorrinolaringologia , 2002,
Abstract: Apesar do termo perda auditiva ocupacional ser relacionado, normalmente, à perda auditiva induzida por ruído, a literatura especializada aponta outros agentes presentes no ambiente de trabalho que podem ser nocivos à saúde auditiva do trabalhador. O chumbo é considerado um desses agentes, e seus efeitos sobre o sistema auditivo vêm sendo investigados por alguns pesquisadores. Existem inúmeros estudos acerca dos efeitos da intoxica o pelo chumbo no organismo, os quais demonstram que múltiplos órg os podem ser afetados, porém, as investiga es sobre os efeitos do chumbo no sistema auditivo s o escassas, além de apresentarem resultados contraditórios. Estudos considerando a exposi o simultanea ao chumbo e outros agentes, como o ruído, por exemplo, s o praticamente inexistentes. O uso industrial desse metal é vasto e, normalmente, as condi es de trabalho presentes num grande número de indústrias brasileiras exp em o trabalhador a elevadas concentra es de chumbo. Os estudos apresentados nesse artigo demonstram que as conseqüências da exposi o ao chumbo sobre o sistema auditivo periférico e central ainda n o s o totalmente esclarecidas. Da mesma forma, devido à seriedade do risco potencial, evidenciam a necessidade de pesquisas futuras que investiguem a exposi o simultanea a mais de um agente nocivo à saúde auditiva do trabalhador.

Revista Brasileira de Otorrinolaringologia , 2003,
Abstract: Atualmente, as legisla es nacionais voltadas à saúde do trabalhador exigem que a audi o seja monitorada apenas quando há exposi o ocupacional ao ruído, n o sendo considerada, assim, a exposi o a produtos químicos. Entretanto, na literatura científica, é bastante clara a preocupa o sobre os efeitos do chumbo no sistema auditivo, uma vez que foram observados efeitos negativos após a exposi o ocupacional a este metal. OBJETIVO: O presente estudo teve como objetivo analisar a amplitude das emiss es otoacústicas evocadas por produto de distor o, em indivíduos com histórico de exposi o ao chumbo e ruído. FORMA DE ESTUDO: Coorte Transversal. MATERIAL E MéTODO: Foram avaliados 69 indivíduos subdivididos em 3 grupos: Grupo I (GI): composto por 29 trabalhadores expostos ao chumbo com exposi o simultanea ao ruído, em seu ambiente de trabalho; Grupo II (GII): composto por 11 trabalhadores expostos ao ruído ocupacional sem exposi o simultanea ou pregressa a outros agentes nocivos à audi o; e Grupo III (GIII): composto por 11 indivíduos com audi o normal, sem histórico de exposi o ao ruído ocupacional ou de outros fatores de risco para a ocorrência de perda auditiva. RESULTADO: Os resultados obtidos n o evidenciaram o efeito tóxico do chumbo nos resultados das emiss es otoacústicas, visto que as menores amplitudes das EOEPD foram observadas no grupo exposto somente ao ruído, mesmo considerando que os indivíduos expostos ao chumbo com exposi o simultanea ao ruído apresentavam longo período de exposi o a este metal bem como ampla varia o do nível de chumbo sérico.

Abstract: one of the goals of a newborn hearing screening program (nhsp) is to have a low retesting rate. aim: to investigate the association between the retesting rate and the bath of newborn babies. study design: cross-sectional contemporary cohort. materials and methods: transient otoacoustic emissions (toe) results have been compared to the information received from the nurse's aide who bathed the babies on the day of the test (373 newborns), and the time interval between the toe study and the last bath (350 newborns). results: significant statistical differences were found in relation to the percentage of retesting when babies were bathed by certain nurse's aides. on the other hand, the percentage of retesting decreased significantly when the time interval between the last bath and the toe study was longer than 7 hours and 50 minutes. conclusion: moisture of the external acoustic meatus, caused by inappropriate protection against water during bath, and the short interval between the bath and the etoe study, could be considered as possible factors causing retesting in nhsp programs.

Abstract: caesalpinia echinata lam. (brazilwood) is an endangered tree species occurring along the eastern coast of brazil from latitudes 5°56′s to 22°56′s. with such a range of distribution it is expected that temperature and daylength may affect plant development, which was examined in this study. one- and five-year-old saplings were grown under controlled photoperiods of 8 h, 12 h and 20 h, and in a greenhouse under natural light during 16 months. in another experiment, one-year-old saplings were cultivated for six months in a growth cabinet, with reduced maximum temperature, and in the greenhouse. leaf number, stem height and stem diameter at the soil surface were evaluated every two months (experiment 1) or every month (experiment 2). in experiment 1, no significant effect of photoperiod on growth of saplings was observed. the increase of leaf number with time followed a polynomial model, and the slope of the curves differed significantly for saplings of the two ages. stem height increased linearly in younger saplings and fitted a polynomial curve in older saplings. stem diameter enlarged linearly with time in all saplings. growth parameters were significantly related to high temperatures. in experiment 2, significant regressions between growth and the maximum daily temperatures recorded were also found for increase of leaf number and stem height increment. our results show that vegetative growth of the saplings of this tropical species is affected by temperature but not by photoperiod.

Abstract: currently, legislations concerning worker's health only require periodic monitoring of individuals who are noise-exposed at work, and exposure to chemicals are not taken into consideration. however, the scientific literature indicates a very clear concern regarding the effects of lead on the auditory system, demonstrating that there are negative effects to the auditory system following occupational exposure to this metal. aim: the aim of this study was to evaluate the amplitude of distortion product otoacoustic emissions (dpoaes) among individuals with a history of exposure to lead and noise. study design: transversal cohort. material and method: we evaluated 69 individuals divided in 3 groups: group i (gi): composed by 29 workers occupationally exposed to both lead and noise; group ii (gii): composed by 11 noise-exposed workers with no other exposure to ototraumatic, and group iii (giii): composed by 11 individuals with normal hearing and no history of exposure to noise or lead. results: the results showed no effect of lead exposure on the otoacoustic emission results, since the smaller eoepd amplitudes were observed in the noise-exposed group, despite the fact that the lead and noise exposed workers had a long history of lead exposure, and a wide variability in blood lead levels.
