ABSTRACT Purpose To analyze the possible differences among the hearing of farmers and their families when compared to the population not exposed to pesticides. Methods Cross-sectional study with 70 smallholder family farmers (research group), with the mean age of 39.7 years, of both sexes and a mean of 23.7 years of exposure to pesticides. We included a control group with 71 participants of both sexes with the mean age of 39.5 years, not exposed to either noise or chemical substances, to compare the results. In stage 1, both groups were submitted to conventional and high-frequency audiometry, and acoustic immittance. In stage 2, only people with normal hearing were submitted to the evoked otoacoustic emissions and suppression effect on transient otoacoustic emissions. Results Significant differences were observed between the groups in the conventional pure-tone and in the high-frequency audiometry, as well as in the acoustic reflex. The most affected frequencies in the conventional pure-tone audiometry ranged from 3 to 6 kHz and, in the high-frequency audiometry, from 9000 to 11200 Hz. As for the transient otoacoustic emissions, the worse suppression effect results were found in the research group. Conclusion There were differences among the hearing of family farmers and the control group. The conventional auditory thresholds are related to the group, age and sex. Farming is associated with impairments in the basal region of the cochlea, absence of acoustic reflex, reduced signal-to-noise ratio of the transient otoacoustic emissions, and dysfunction in the olivocochlear efferents of the auditory system.

RESUMO Objetivo Analisar as possíveis diferenças na audição de agricultores e suas famílias em comparação com população não exposta aos agrotóxicos. Método Estudo transversal, com 70 participantes (grupo pesquisa), com média de idade de 39,7 anos, de ambos os sexos, proprietários de pequenos estabelecimentos agrícolas vinculados a agricultura familiar e tempo de exposição médio aos agrotóxicos de 23,7 anos. Um grupo controle com 71 participantes de ambos os sexos, sem exposição a ruído e agentes químicos, com idade média de 39,5 anos, foi incluído para a comparação dos resultados. Na etapa 1, ambos os grupos foram submetidos a audiometria convencional e de altas frequências e imitanciometria. Na etapa 2, somente os normoouvintes foram submetidos as emissões otoacústicas evocadas e efeito de supressão das emissões otoacústicas transientes. Resultados Observou-se diferenças significativas entre os grupos para audiometria tonal convencional e de altas frequências, e no reflexo acústico. As frequências mais afetadas na audiometria tonal convencional foram 3 a 6kHz e na audiometria de altas frequências foram as frequências de 9.000 e 11.200 Hz. Nas emissões otoacusticas transientes, observou-se no efeito de supressão piores resultados no grupo de pesquisa. Conclusão Conclui-se que houve diferenças na audição dos agricultores familiares em comparação com o grupo controle. Os limiares auditivos convencionais estão relacionados em função do grupo, idade e gênero. O trabalho na agricultura está associado com o comprometimento na região basal da cóclea, à ausência de reflexo acústico, à redução da relação sinal/ruído das emissões otoacústicas transientes e à disfunção do sistema auditivo eferente olivococlear.

La alfarería Aguada Portezuelo del Noroeste Argentino (ca. 600-900 d.C.) presenta una gran complejidad en sus intervenciones plásticas siendo su marcada policromía uno de sus aspectos más llamativos. La utilización de una multiplicidad de pigmentos por parte de los alfareros antiguos para obtener los diferentes colores hace necesario un mejor entendimiento de las cadenas operativas involucradas en el manejo de estos. En este trabajo presentamos los resultados obtenidos a partir de la investigación centrada en una serie de experimentaciones con briquetas cerámicas, su decoración con diferentes pigmentos naturales y su posterior cocción en distintas atmósferas y temperaturas. Asimismo, se presentan algunos datos arqueométricos obtenidos en relación con la obtención de diferentes colores.

Aguada Portezuelo pottery from Northwest Argentina (ca.600-900 AD) presents a great complexity in its plastic interventions, its marked polychromy being one of its most fascinating aspects. The use of a multiplicity of pigments by ancient potters to obtain different colors requires a better understanding of the operational chains involved in handling them. In this paper, we present the results obtained through the research focused on a series of experiments with ceramic briquettes, their decoration with different natural pigments, and their subsequent firing in different atmospheres and temperatures. Additionally, some archaeometric data in relation to obtaining different colors are presented.

Abstract The objective of this study was to determine the gingival state and presence of red complex bacteria in saliva samples of 12-year-old schoolchildren. A calibrated periodontist evaluated biofilm index (BI) (Silness and Löe, 1964), presence of calculus, and gingival index (GI) (Silness and Löe, 1967) in sixty two 12-year-old students of Carmen Lyra School. Saliva samples were collected from each student. The DNA of each sample was extracted and amplified by the polymerase chain reaction (PCR) technique, using specific primers. The BI was 1.18. Calculus was present in 40.40% of the schoolchildren examined; 19.4% was supragingival calculus and 21% both supragingival and subgingival calculus. The GI was 0.97, which according to Silness and Löe is mild gingivitis. Gingivitis was present in 96.8% of the children examined. Regarding the PCR tests: 18 of the samples (31.58%) did not present any of the bacteria analyzed and the remaining 39 samples (68.42%) were positive for at least the presence of red complex bacteria. Within the limitations of this study, it is concluded that the prevalence of gingivitis and calculus is high in the sample examined, and the gingival state observed in the study population, may be related to the presence of red complex bacteria.

Resumen El objetivo de este estudio era determinar el estado gingival y la presencia de bacterias del complejo rojo en muestras de saliva de niños de 12 años de la Escuela Carmen Lyra. Una periodoncista calibrada evaluó en 62 estudiantes de 12 años de la Escuela Carmen Lyra, el índice de biofilme (IB) (Silness y Löe, 1964), la presencia de cálculo y el índice gingival (IG) (Silness y Löe, 1967). Se recolectaron muestras de saliva de cada estudiante. El ADN de cada muestra fue extraído y amplificado por medio de la prueba PCR, empleando primers específicos, para determinar la presencia de bacterias del complejo rojo. El IB fue de 1.18. El cálculo estuvo presente en el 40.40% de la muestra, se encontró 19.4% de cálculo en supragingival y 21% tanto en supragingival como en subgingival. El IG fue de 0.97, que de acuerdo con Silness y Löe es una gingivitis leve. La gingivitis estuvo presente en el 96.8 % de los niños examinados. Con respecto a las pruebas PCR: 18 de las muestras (31.58 %) no presentaron ninguna de las bacterias analizadas y las 39 muestras restantes (68.42%) fueron positivas por lo menos a la presencia de las bacterias del complejo rojo. Dentro de las limitaciones de este estudio, se concluye que la prevalencia de gingivitis y cálculo es alta en la muestra examinada y el estado gingival observado puede estar relacionado con la presencia de bacterias del complejo rojo.

Abstract Introduction: The use of physical agents in physical therapy (PT) requires clinical reasoning, as well as knowledge of their risks and contraindications; however, deficiencies may be observed when used in clinical practice. Objective: To implement the Objective Structured Clinical Evaluation (OSCE) method for the assessment of clinical skills among physical therapy specialty students when using physical agents. Materials and methods: A pilot, non-experimental, cross-sectional study was conducted in 114 physical therapy students enrolled during the first semester of 2019 in a physical agents course offered at the Universidad Andres Bello, Santiago, Chile. The OSCE consisted of 7 peer-validated stations, in which various skills were implemented in simulated clinical scenarios to achieve learning outcomes associated with the use of physical agents, namely: S1: connective tissue flexibility; S2: muscle relaxation; S3: analgesia; S4: drainage; S5: muscle strengthening; S6: parameter interpretation; and S7: equipment installation. Observers at each station assessed students' clinical skills and decision-making using a checklist. OSCE scores were described using medians and interquartile ranges, representing the data dispersion between the 25th and 75th percentile (P25-P75). Station scores by sex were compared using the Mann-Whitney U test. Results: Median scores were higher than the minimum passing score in stations S1 (66, IQR: 52-70), S2 (55, IQR: 45-60), S3 (60, IQR: 50-69), S4 (65, IQR: 55-73), and S7 (40, IQR: 33-45), but they were below the passing score in stations S5 (54, IQR:46-65) and S6 (10, IQR: 9-13). In addition, 101 (88.59%) students had a global passing score in the OSCE. Conclusion: The OSCE scores obtained by the participants show their attainment of clinical skills when using physical agents since most of them obtained a global passing score; however, reinforcing the clinical skills for parameter interpretation is necessary, considering that the lowest mean score was obtained in said station.

Resumen Introducción. El uso de agentes físicos en el ejercicio de la fisioterapia requiere razonamiento clínico y saber sus riesgos y contraindicaciones, aunque en ocasiones se observan deficiencias al utilizarlos en la práctica clínica. Objetivo. Implementar la metodología de Evaluación Clínica Objetiva Estructurada (ECOE) para la evaluación de habilidades clínicas en estudiantes de fisioterapia al aplicar agentes físicos. Materiales y métodos. Se realizó un estudio piloto transversal no experimental en 114 estudiantes de fisioterapia inscritos en el primer semestre de 2019 en la asignatura de agentes físicos en la Universidad Andrés Bello, Santiago de Chile, Chile. La ECOE consistió de siete estaciones validadas por pares en las que se implementaron diversas habilidades en escenarios clínicos simulados para lograr resultados de aprendizaje asociados al uso de agentes físicos, a saber: E1: Flexibilidad tejido conectivo, E2: Relajación muscular, E3: Analgesia, E4: Drenaje, E5: Fortalecimiento, E6: Interpretación de parámetros y E7: Instalación de equipo. En cada estación, las habilidades clínicas y toma de decisiones fueron evaluadas por observadores usando listas de verificación. Las puntuaciones en la ECOE se describieron usando medianas y rangos intercuartiles, representado la dispersión de los datos entre el percentil 25 y 75 (P25-P75). Los puntajes en cada estación fueron comparados por género mediante la prueba de U de Mann-Whitney. Resultados. Las medianas de puntaje fueron superiores al puntaje aprobatorio en las estaciones E1 (66, RIC: 52-70), E2 (55, RIC: 45-60), E3 (60, RIC: 50-69), E4 (65, RIC: 55-73) y E7(40, RIC: 33-45), pero inferiores en las estaciones E5 (54, RIC: 46-65) y E6 (10, RIC: 9-13). Además, 101 estudiantes (88.59%) obtuvieron un puntaje aprobatorio global en la ECOE. Conclusión. Los puntajes obtenidos en la ECOE por los participantes demuestran el logro de habilidades clínicas al utilizar agentes físicos, pues la mayoría obtuvo una nota aprobatoria global. No obstante, se requiere reforzar las habilidades clínicas de interpretación de parámetros, estación en la que se obtuvo la media de puntaje más baja.

Abstract Introduction: Hearing loss associated with older adults is a very prevalent condition. Hearing aids are usually implemented as treatment, but there is low adherence exhibited, which can be around 50%. Aim: To assess whether the Active Communication Education (ACE) hearing rehabilitation program improves adherence to hearing aid use. Material and Method: A randomized controlled clinical trial was carried out to evaluate the effectiveness of the ACE program added to a tele-educational reinforcement to improve adherence to hearing aid use. The project was approved by the ethics committee of the institution and each participant signed an informed consent. Adherence was evaluated using the CIRUA scale and Dr. Yueh scale. Each participant was followed at home in controls every 3 months up to 1 year after the intervention by trained interviewers. Results: 202 participants were included, 101 in each branch. The median age was 78 years and 59.9% of the sample was female. The average bone PTA was 48.59 dB and air PTA was 55 dB. Adherence in the control group was 65.91% and 62.30%. In the interventional group, adherence was 78.41% and 72.28%. There were significant differences in the percentage of adherence between the control and experimental groups according to CIRUA (p = 0.027) and Yueh (p = 0.011). Conclusion: The ACE auditory rehabilitation program improves adherence to hearing aid use in older adults with hearing loss. This study represents one of the largest published efforts to evaluate the effectiveness of auditory rehabilitation programs in older adults with hearing loss.

Abstract Introduction: It is estimated that up to 30% of the population over 65 years of age present hearing loss. A validated intervention for hearing loss in older adults is the use of hearing aids, but the problem is that up to 50% of older adults do not use them. Aim: To estimate the hearing aid adherence in elderly population with hearing loss who are beneficiaries of the GES program “Bilateral hearing loss in people over 65 who require hearing aids” in a hospital in Santiago, Chile. Material and Method: The control arm of a randomized clinical trial was used to estimate adherence to hearing aid with validated and structured questionnaires, by trained interviewers who visited the beneficiaries of the program at three, six, nine and twelve months posterior to the intervention. Results: 101 older adults were included. The average age was 76.3 years. When analyzing adherence as “use for more than 8 hours a day during the last two weeks”, adherence at 3 months was 56.8%, at 6 months 62.6%, at 9 months 63.2%, and at 12 months 54.5%. When analyzing considering use between 4-8 h/day, the adherence during the follow-up was between 73.8% and 87.3%. According to Dr. Yueh's questionnaire, adherence at 3 months was 64.7%, at 6 months 63.9%, at 9 months 73.7%, and at 12 months 67.8%. Conclusion: The results of the present analysis show an excellent adherence to hearing aids in a group of Chilean population, which represents a positive outcome regarding the effectiveness of this particular public policy.

Resumen Introducción: Se estima que hasta un 30% de la población mayor de 65 años presenta hipoacusia. Una intervención validada para la hipoacusia en adultos mayores es el uso de audífonos, pero el problema es que hasta un 50% de los adultos mayores no los utiliza. Objetivo: Estimar la adherencia al uso de audífonos en adultos mayores beneficiarios del programa GES de “Hipoacusia bilateral en mayores de 65 años que requieran audífonos” en un hospital en Santiago, Chile.

RESUMO Objetivo: verificar a relação entre auto referência de tontura, o grau, a simetria da perda auditiva, idade e sexo, em idosos. Métodos: estudo retrospectivo que incluiu a análise de 440 registros de idosos com média de idade de 72,9 anos, cadastrados no período de 2011 a 2015 em um Serviço de Reabilitação Auditiva. Foram aplicados modelos de regressão logística binária entre as variáveis, os dados foram tabulados e processados pelo software SPSS 24.00. Para todos os testes, os valores de alfa foram considerados significantes quando menores que 0,05. Resultado: na amostra, 78 (17,7%) idosos apresentaram perda auditiva assimétrica, sendo que destes, 27 (34,6%) referiram queixa de tontura. A queixa de tontura apresentou relação estatisticamente significante com o sexo feminino (p<0,001), com o grau da perda auditiva severa (p<0,001), com a idade inferior a 70 anos (DP 8,6 anos) e com a assimetria da perda auditiva (p<0,001). Conclusão: no presente estudo, idosos do sexo feminino, mais jovens, com perda auditiva assimétrica e grau de perda auditiva severo apresentaram queixa auto referida de tontura. Estes resultados sugerem que essa população seja rotineiramente rastreada sobre problemas de equilíbrio, com o objetivo de fornecer programas de reabilitação, a fim de prevenir futuras quedas.

ABSTRACT Purpose: to verify the association between self-reported dizziness, degree and symmetry of hearing loss, age and gender in a sample of older adults. Methods: this retrospective study included the analysis of 440 records of older adults with a mean age of 72.9 years, enrolled from 2011 to 2015 in an auditory rehabilitation service. Binary logistic regression models were performed between the variables, and the data was analyzed using the SPSS 24.00 software. For all tests, alpha values were considered significant when lower than 0.05. Results: in the sample, 78 (17.7%) older adults had asymmetric hearing loss, and 27 (34.6%) of them complained of dizziness. Self-reported complaint of dizziness was significantly associated with female gender (p<0,001), to severe hearing loss (p<0,001), age under 70 years, and with asymmetric hearing loss(p<0,001). Conclusion: in this study, younger female elderlies with severe asymmetric hearing loss presented self-reported complaint of dizziness . These results suggest that this population should be routinely screened for balance problems in order to provide rehabilitation programs to avoid future falls.

ABSTRACT OBJECTIVE To determine if there are existing healthcare access inequities among the deaf Chilean population when compared to the general Chilean population. METHODS Data were obtained from a population-based national survey in Chile. In total, 745 prelingually deaf individuals were identified. The number of times the person used the healthcare system was dichotomized and analyzed using a multivariate logistic regression model. RESULTS Prelingually deaf people had lower incomes, fewer years of education, and greater rates of unemployment and poverty when compared with the general population. Moreover, they visited more general practitioners, mental health specialists, and other medical specialists. On average, they attended more appointments for depression but had fewer general checkups and gynecological appointments than the general population. CONCLUSIONS Deaf people in Chile have a lower socioeconomic status than the rest of the Chilean population. The results from this study are similar to the findings reported for high-income countries, despite differences in the magnitude of the associations between being deaf and healthcare access. Further studies should be conducted to determine the health status of deaf people in Chile and other Latin American countries and what factors are associated with a significantly lower prevalence of gynecological appointments among deaf women when compared with non-deaf women.

Image analysis software (IAS) has been increasingly applied in archaeology over the last years. The main observed applications have been in rock art studies and archaeological ceramic analyses. The manipulation of images obtained by different means, such as digital cameras, scanners, scanning electron microscopy, binocular and petrographic microscopes, has allowed to maximize the information contained in each of the images obtained. In this paper, we present an evaluation and testing of the application of IAS for the technological characterization of six archaeological sherds belonging to Saujil Culture from the Early Period (200 BC- AD 400) in the Northwestern region of Argentine. We also discuss the main scopes and limitations of this methodological approach.

El software de análisis de imágenes (SAI) se ha empezado a utilizar en los últimos años crecientemente en arqueología. Las principales aplicaciones observadas han sido en los análisis de arte rupestre y cerámicas arqueológicas. La manipulación de las imágenes obtenidas por diferentes medios (cámaras digitales, escáners, microscopía electrónica de barrido, lupas binoculares y microscopios polarizadores) ha permitido maximizar la información contenida en cada una de ellas. En este trabajo presentamos una evaluación y testeo de la aplicación del SAI en la caracterización tecnológica de seis fragmentos de cerámicas arqueológicas pertenecientes a la Cultural Saujil del Período Agroalfarero Temprano (a.C. 200-400 d.C.) del noroeste argentino. Asimismo, se discuten críticamente los principales alcances y limitaciones de esta aproximación metodológica.

In this paper we will analyse the material, symbolic, and subjective dimensions of a very particular space geographically located in Sierra de Ancasti (Province of Catamarca, in the north western of Argentina) known as La Tunita. We argue that several and unique natural and spatial attributes in La Tunita favoured its incorporation to the social dynamic during the Regional Period of Integration (ca. s. III D.C. - s. XI / XII). La Tunita distinguished itself for the existence of an important array of rock art manifestations which in turn materialize the Aguada culture cosmovision. This place would have played an important role in influencing significantly at a symbolic-ideological level, allowing arranging the natural environment and transforming it into a social space of great significance in the macro regional context. Despite of the prevalence of Aguada imprint, evidence suggests that other social groups in the course of history could have operated from a similar logic. We assume that some pictures of La Tunita are related to the conflicts and social tensions that seem to have occurred in times of Aguada. In this way, we pose that the images and some rituals have become important allies in the exercise of control and power within society to assert against other groups when social interaction in a vast territory should have required the adoption of practices which reinforce some ideological aspects in certain places.

En este trabajo analizamos las dimensiones materiales, simbólicas y subjetivas de un particular espacio emplazado en la Sierra de Ancasti (provincia de Catamarca, noroeste argentino) conocido como La Tunita. Alegamos que singulares atributos naturales y espaciales favorecieron su incorporación a la dinámica social durante el Período de Integración Regional (ca. s. III d.C. hasta el s. XI o XII). La Tunita se distingue por un importante conjunto de manifestaciones rupestres que visibilizan la cosmovisión Aguada en una vía de transito que articula la Sierra de Ancasti con el oeste catamarqueño. Este lugar habría jugado un importante rol al incidir de manera significativa en el plano simbólico-ideológico, permitiendo ordenar el entorno natural y transformarlo en un espacio social de gran significación en el contexto macroregional. No obstante el predominio de la impronta Aguada, la evidencia sugiere que otros grupos sociales en su devenir histórico pudieron haber operado desde una lógica similar. Asumimos que algunas imágenes de La Tunita guardan relación con los conflictos y tensiones sociales que parecen haber ocurrido en tiempos de Aguada. Así planteamos que las imágenes y ciertos rituales se constituyeron en aliados importantes en el ejercicio del control y el poder tanto al interior de la sociedad como para reafirmarse ante otros grupos, en momentos donde la interacción social en un amplio territorio debió requerir la adopción de prácticas tendientes a reforzar aspectos ideológicos en determinados lugares.

Introduction: Hearing loss is a prevalent condition in elderly population. However, the low adherence to hearing aids is a fact. Aim: To evaluate the utility of a standardized counselling program in elderly patients with hearing loss. Material and methods: A clinical trial was carried out, approved by the Hospital ethics committee. Patients with 65years and older with hearing loss were included. We assessed adherence at a follow-up of 6 months. Results: 180 patients were evaluated, corresponding to 90 control and 90 rehabilitated patients. The overall adherence of hearing aids use was 78%. There was no difference in sex, age, and level of hearing loss between groups. The average daily hours of use in the control group was 6.9 hours, compared with the 9.6 hours in the intervention group (p <0.0001). There was a significant association between the intervention and regular hearing aid use, with 80% of patients who used it regularly in the intervention group compared with 8.9% in the control group (p <0.001). Discussion: The intervention implemented has shown excellent preliminary results in terms of time of use of the hearing aid. It would be useful to include this intervention in the hearing loss national public policy.

Introducción: La hipoacusia es una condición prevalente en adultos mayores. Sin embargo, la baja adherencia al uso del audífono representa una realidad. Objetivo: Evaluar la utilidad de un programa de intervención para mejorar adherencia en pacientes con hipoacusia mayores de 65 años usuarios de audífono. Material y método: Ensayo clínico aprobado por Comité de Ética. Se incluyeron pacientes beneficiarios del GES de hipoacusia. Se evaluó adherencia al audífono en un corte a 6 meses. Resultados: Fueron evaluados 180 pacientes, correspondiendo a 90 pacientes control y 90 intervenidos. La adherencia global al uso del audífono fue de 78%. No hubo diferencia en los grupos por sexo, edad, ni grado de hipoacusia. El promedio de horas diarias de uso en el grupo control fue de 6,9 horas, comparado con el del grupo intervenido que fue 9,6 horas (p <0,0001). Hubo una asociación significativa entre la intervención y la regularidad del uso del audífono, con 80% de pacientes que lo usaban regularmente en el grupo intervenido contra el 8,9% en el grupo control (p <0,001). Discusión: La intervención implementada ha demostrado excelentes resultados preliminares en términos de tiempo de uso del audífono, por lo que sería de utilidad implementaria como parte de la política GES y difundir su uso.

OBJETIVO: Comparar o desempenho das atividades diárias relacionadas a funções do sistema auditivo periférico e central entre trabalhadores expostos e não expostos a solventes. MÉTODOS: Participaram do estudo 96 trabalhadores, sendo 48 expostos a solventes e 48 não expostos, pareados por escolaridade, idade e sexo. Os procedimentos de avaliação incluíram: audiometria de tons puros (500 a 8.000 Hz), para avaliar o sistema auditivo periférico; teste de Random Gap Detection, para avaliar o sistema auditivo central; e o Amsterdam Inventory for Auditory Disability and Handicap, para estudar a performance em atividades da vida diária que envolvem a audição, por meio de autoavaliação. Teste t de student e a análise de covariância (ANCOVA) foram utilizados. Foram calculadas as correlações de Pearson entre os resultados dos três testes. RESULTADOS: Sujeitos expostos a solventes tiveram limiares auditivos significativamente piores na orelha direita que os sujeitos não expostos. Apresentaram também resultados significativamente piores no teste de Random Gap Detection e funcionamento autorreportado significativamente mais alterado que os sujeitos não expostos. Foi observada correlação significativa entre os resultados do Amsterdam Inventory for Auditory Disability and Handicap e a média binaural dos limiares auditivos e com os resultados do teste de Random Gap Detection. CONCLUSÕES: A exposição a solventes está associada com as dificuldades da vida diária relacionadas com as funções do sistema auditivo periférico e central.

OBJECTIVE: To compare hearing performance relating to the peripheral and central auditory system between solvent-exposed and non-exposed workers. METHODS: Forty-eight workers exposed to a mixture of solvents and 48 non-exposed control subjects of matched age, gender and educational level were selected to participate in the study. The evaluation procedures included: pure-tone audiometry (500 - 8,000 Hz), to investigate the peripheral auditory system; the Random Gap Detection test, to assess the central auditory system; and the Amsterdam Inventory for Auditory Disability and Handicap, to investigate subjects' self-reported hearing performance in daily-life activities. A Student t test and analyses of covariance (ANCOVA) were computed to determine possible significant differences between solvent-exposed and non-exposed subjects for the hearing level, Random Gap Detection test and Amsterdam Inventory for Auditory Disability and Handicap. Pearson correlations among the three measures were also calculated. RESULTS: Solvent-exposed subjects exhibited significantly poorer hearing thresholds for the right ear than non-exposed subjects. Also, solvent-exposed subjects exhibited poorer results for the Random Gap Detection test and self-reported poorer listening performance than non-exposed subjects. Results of the Amsterdam Inventory for Auditory Disability and Handicap were significantly correlated with the binaural average of subject pure-tone thresholds and Random Gap Detection test performance. CONCLUSIONS: Solvent exposure is associated with poorer hearing performance in daily life activities that relate to the function of the peripheral and central auditory system.

Se observó correlación significativa entre los resultados del Amsterdam Inventory for Auditory Disability and Handicap y el promedio binaural de los umbrales auditivos y con los resultados de la prueba de Random Gap Detection. CONCLUSIONES: La exposición a solventes está asociada con las dificultades de la vida diaria relacionadas con las funciones del sistema auditivo periférico y central.

OBJETIVO: Comparar o desempenho das atividades diárias relacionadas a funções do sistema auditivo periférico e central entre trabalhadores expostos e não expostos a solventes. MÉTODOS: Participaram do estudo 96 trabalhadores, sendo 48 expostos a solventes e 48 não expostos, pareados por escolaridade, idade e sexo. Os procedimentos de avaliação incluíram: audiometria de tons puros (500 a 8.000 Hz), para avaliar o sistema auditivo periférico; teste de Random Gap Detection, para avaliar o sistema auditivo central; e o Amsterdam Inventory for Auditory Disability and Handicap, para estudar a performance em atividades da vida diária que envolvem a audição, por meio de autoavaliação. Teste t de student e a análise de covariância (ANCOVA) foram utilizados. Foram calculadas as correlações de Pearson entre os resultados dos três testes. RESULTADOS: Sujeitos expostos a solventes tiveram limiares auditivos significativamente piores na orelha direita que os sujeitos não expostos. Apresentaram também resultados significativamente piores no teste de Random Gap Detection e funcionamento autorreportado significativamente mais alterado que os sujeitos não expostos. Foi observada correlação significativa entre os resultados do Amsterdam Inventory for Auditory Disability and Handicap e a média binaural dos limiares auditivos e com os resultados do teste de Random Gap Detection. CONCLUSÕES: A exposição a solventes está associada com as dificuldades da vida diária relacionadas com as funções do sistema auditivo periférico e central.

OBJECTIVE: To compare hearing performance relating to the peripheral and central auditory system between solvent-exposed and non-exposed workers. METHODS: Forty-eight workers exposed to a mixture of solvents and 48 non-exposed control subjects of matched age, gender and educational level were selected to participate in the study. The evaluation procedures included: pure-tone audiometry (500 - 8,000 Hz), to investigate the peripheral auditory system; the Random Gap Detection test, to assess the central auditory system; and the Amsterdam Inventory for Auditory Disability and Handicap, to investigate subjects' self-reported hearing performance in daily-life activities. A Student t test and analyses of covariance (ANCOVA) were computed to determine possible significant differences between solvent-exposed and non-exposed subjects for the hearing level, Random Gap Detection test and Amsterdam Inventory for Auditory Disability and Handicap. Pearson correlations among the three measures were also calculated. RESULTS: Solvent-exposed subjects exhibited significantly poorer hearing thresholds for the right ear than non-exposed subjects. Also, solvent-exposed subjects exhibited poorer results for the Random Gap Detection test and self-reported poorer listening performance than non-exposed subjects. Results of the Amsterdam Inventory for Auditory Disability and Handicap were significantly correlated with the binaural average of subject pure-tone thresholds and Random Gap Detection test performance. CONCLUSIONS: Solvent exposure is associated with poorer hearing performance in daily life activities that relate to the function of the peripheral and central auditory system.
