- Caracterização eletrofisiológica da audição em indivíduos com Síndrome de Down(2016) KAZAN, Hellen Medeiros; SAMELLI, Alessandra Giannella; NEVES-LOBO, Ivone Ferreira; MAGLIARO, Fernanda Cristina Leite; LIMONGI, Suelly Cecília Olivan; MATAS, Carla GentileABSTRACT Introduction Few studies have performed Brainstem (BAEP) and P300 Auditory Evoked Potentials simultaneously to assess central auditory pathways in normal hearing individuals with Down syndrome (DS), mainly because of the difficulty in applying these procedures to this population. Previous studies have suggested that individuals with DS might present different patterns of response compared with those of individuals with typical development; nevertheless, the identification of these potentials would be crucial for the establishment of an accurate audiological diagnosis. Purpose To characterize BAEP and P300 in normal-hearing individuals with DS. Methods BAEP and P300 were analyzed in 17 individuals with DS and in 21 individuals with typical development aged 7 to 15 years. The results were quantitatively and qualitatively analyzed using descriptive measures and hypothesis tests. Results In the quantitative analysis, latency values were lower in the BAEP for the DS group, with statistically significant difference for wave V and interpeaks III-V and I-V; there were no significant differences in the P300 latency values. In the qualitative analysis, there were a larger number of individuals with early values for BAEP latencies and late latencies for P300 in the DS group; both comparisons showed statistically significant differences. Conclusion Children and adolescents with DS can present early responses to the components of BAEP, suggesting that their auditory pathway requires less time for the neural transmission of acoustic stimuli to the brainstem. Concerning P300, individuals with DS may present increased latencies, suggesting impairment in the central auditory pathway for the cortical processing of auditory information.
- Insertion and performance of Speech-Language Pathology and Audiology in Family Health Support Centers(2014) MOLINI-AVEJONAS, Daniela Regina; ABOBOREIRA, Meiriane Silva; COUTO, Maria Inês Vieira; SAMELLI, Alessandra GiannellaPURPOSE: To analyze the structure of the Centers for Supporting the Family Health (NASF), in 2010, identify the satisfaction degree of speech language pathologists who work in this area and compare the model proposed by the Brazilian Ministry of Health with practice. METHODS: Prospective and descriptive study, with 40 speech language pathologists inserted in NASF type one, from all Brazilian regions, in 2010. It was used a questionnaire with nine questions related to different topics (work infrastructure, NASF team, actions developed by these professionals and satisfaction about the work), sent by electronic mail to the speech language pathologists. Descriptive statistics, χ2, ANOVA and Pearson coefficient of variation were used to analyze variables. Significance level of 5% was adopted. RESULTS: The speech language pathologists reported that, in their working places (NASF), there was an average of 12.2 Health Family Teams, with 8.9 professionals and 1.6 speech language pathologists. Most of them work 40 hours per week. Routine activities cited by speech language pathologists were: promotion and health prevention actions, matricial, therapies, support to health community workers, referrals, home visits, intersectoral actions and administrative tasks. There was variability in the satisfaction score: the majority of interviewees indicated the degree ""Somewhat satisfied"" for work infrastructure and referrals, as well as reported ""Very satisfied"" degree for home visits and support for health community workers. Comparing the model proposed by the Ministry of Health with the speech language pathologists' practices, there was no significant difference. The results show that 40% of speech language pathologists consider that the NASF actions are below the proposed model. CONCLUSION: The NASF structure varied in terms of the number of Family Health Teams, professionals involved and actions performed. There was also significant variability in the satisfaction degree among the subjects studied.
- Interação entre diabetes mellitus e hipertensão arterial sobre a audição de idosos(2015) ROLIM, Laurie Penha; RABELO, Camila Maia; LOBO, Ivone Ferreira Neves; MOREIRA, Renata Rodrigues; SAMELLI, Alessandra GiannellaABSTRACT Introduction: Chronic diseases and metabolic changes may act as accelerating factor in the degeneration of the auditory system due to age. However, studies involving an association between hearing loss and diabetes mellitus (DM) and hypertension (HA) in the elderly have shown controversial conclusions. Thus, further studies on this topic are needed in order to elucidate the effect of these chronic diseases on the auditory system. Aim: To compare the hearing thresholds of elderly patients with DM, HA and DM + HA with a control group (CG). Methods: Retrospective study was conducted through survey charts of 80 elderly people with full hearing assessment, between 2008 and 2012. Subjects were divided into four groups: DM, HA, DM + HA and without chronic diseases known (CG). The ANOVA, Tukey and Mauchly tests, with a significance level of 0.05, were used. Results: There was no statistically significant difference between the ears, which are grouped. Comparisons between the means of hearing thresholds of CG and DM or HA showed no statistically significant differences. However, a statistically significant difference in the comparison between these three groups and DM + HA group for several of the frequencies evaluated was observed. Conclusion: It was found that older adults with DM and hypertension associated showed greater hearing impairment in comparison with the other groups, suggesting a synergistic effect of the two chronic diseases on hearing.
article 6 Citação(ões) na Scopus Comparing audiological evaluation and screening: a study on presbycusis(2011) SAMELLI, Alessandra Giannella; NEGRETTI, Camila Aparecida; UEDA, Kerli Saori; MOREIRA, Renata Rodrigues; SCHOCHAT, ElianeGiven the high prevalence of presbycusis and the damage it brings about, a screening test can be useful in the identification of hearing loss in primary care. Aim: To estimate the prevalence of hearing loss in a representative sample of elderly people living at Butantan using an audiological screening method (questionnaire) and a basic audiological evaluation; to compare the results of the two kinds of evaluations, checking the validity of this tool for hearing loss screening. Design: Cross sectional descriptive study. Materials and Methods: 200 individuals (above 60 years old, both genders) were randomly selected to undergo audiological screening (questionnaire). Another randomly selected group encompassed 100 individuals who were submitted to a set of audiological tests. Then, we compared the results from the two methods. Results: There were no statistically significant associations between the questionnaire and the degree of hearing loss of the patients. Conclusion: The prevalence of hearing loss in our sample was of 56% in the screening and of 95% when checked by the audiological evaluation. Therefore, screening was not proven valid to assess hearing when compared to audiological evaluation.- P300 in workers exposed to occupational noise(2012) MASSA, Camila Goncalves Polo; RABELO, Camila Maia; MOREIRA, Renata Rodrigues; MATAS, Carla Gentile; SCHOCHAT, Eliane; SAMELLI, Alessandra GiannellaThe harm upon the central auditory pathways of workers exposed to occupational noise has been scarcely studied. Objective: To assess the central auditory pathways by testing the long latency auditory evoked potentials (P300) of individuals exposed to occupational noise and controls. Method: This prospective study enrolled 25 individuals with normal hearing thresholds. The subjects were divided into two groups: individuals exposed to occupational noise (13 subjects; case group) and individuals not exposed to occupational noise (12 subjects; control group). The P300 test was used with verbal and non-verbal stimuli. Results: No statistically significant differences were found between ears for any of the stimuli or between groups. The groups had no statistically significant difference for verbal or non-verbal stimuli. Case group subjects had longer latencies than controls. In qualitative analysis, a greater number of altered P300 test results for verbal and non-verbal stimuli was seen in the case group, despite the absence of statistically significant differences between case and control subjects. Conclusion: Individuals exposed to high sound pressure levels had longer P300 latencies in verbal and non-verbal stimuli when compared to controls.
bookPart Ações de proteção para prevenção de perdas auditivas relacionadas ao trabalho(2015) SAMELLI, Alessandra Giannella; FIORINI, Ana Claudia- Does cognitive impairment precede self-reported poor hearing? Results from the English longitudinal study of ageing(2023) VALSECHI, Felipe Eduardo; PAIVA, Karina Mary de; HILLESHEIM, Danubia; XAVIER, Andre Junqueira; SAMELLI, Alessandra Giannella; OLIVEIRA, Cesar de; D'ORSI, EleonoraObjective To investigate whether cognitive impairment precedes self-reported poor hearing in adults aged 50 and older over a 14-year period. Design Biennial longitudinal study. Study sample The data came from the English Longitudinal Study of Ageing carried out in England between 2002 and 2016, with 11,391 individuals aged 50 years and older. For this study, ELSA participants who had a positive perception of hearing at the beginning of the analysis in 2002 (n = 8,895) were eligible. The dependent variable was self-reported poor hearing, and the exposure measure was cognitive impairment. The analyses were performed using Generalised Estimation Equations and adjusted for gender, age, educational level, household wealth, smoking, alcohol consumption, depressive symptoms, ADL/IADL disability, physical activity level, diabetes, and cardiovascular disease. Results The results showed 33% increased odds of self-reported poor hearing in individuals with cognitive impairment. In the fully adjusted model, individuals who presented cognitive impairment in the previous wave had, over time, 10% increased odds (95% CI: 1.02; 1.19) of presenting self-reported poor hearing. Conclusions The exposure to cognitive impairment was associated with a subsequent self-reported poor hearing. These data represent important tools for improving cognitive and hearing impairment diagnosis and treatment.
- Evaluation of Subtle Auditory Impairments with Multiple Audiological Assessments in Normal Hearing Workers Exposed to Occupational Noise(2023) SAMELLI, Alessandra Giannella; ROCHA, Clayton Henrique; KAMITA, Mariana Keiko; LOPES, Maria Elisa Pereira; ANDRADE, Camila Quintiliano; MATAS, Carla GentileRecent studies involving guinea pigs have shown that noise can damage the synapses between the inner hair cells and spiral ganglion neurons, even with normal hearing thresholds-which makes it important to investigate this kind of impairment in humans. The aim was to investigate, with multiple audiological assessments, the auditory function of normal hearing workers exposed to occupational noise. Altogether, 60 workers were assessed (30 in the noise-exposure group [NEG], who were exposed to occupational noise, and 30 in the control group [CG], who were not exposed to occupational noise); the workers were matched according to age. The following procedures were used: complete audiological assessment; speech recognition threshold in noise (SRTN); speech in noise (SN) in an acoustic field; gaps-in-noise (GIN); transient evoked otoacoustic emissions (TEOAE) and inhibitory effect of the efferent auditory pathway; auditory brainstem response (ABR); and long-latency auditory evoked potentials (LLAEP). No significant difference was found between the groups in SRTN. In SN, the NEG performed worse than the CG in signal-to-noise ratio (SNR) 0 (p-value 0.023). In GIN, the NEG had a significantly lower percentage of correct answers (p-value 0.042). In TEOAE, the NEG had smaller amplitude values bilaterally (RE p-value 0.048; LE p-value 0.045) and a smaller inhibitory effect of the efferent pathway (p-value 0.009). In ABR, the NEG had greater latencies of wave V (p-value 0.017) and interpeak intervals III-V and I-V in the LE (respective p-values: 0.005 and 0.04). In LLAEP, the NEG had a smaller P3 amplitude bilaterally (RE p-value 0.001; LE p-value 0.002). The NEG performed worse than the CG in most of the assessments, suggesting that the auditory function in individuals exposed to occupational noise is impaired, even with normal audiometric thresholds.
- Referred speech-language and hearing complaints in the western region of Sao Paulo, Brazil(2014) SAMELLI, Alessandra Giannella; RONDON, Silmara; OLIVER, Fatima Correa; JUNQUEIRA, Simone Renno; MOLINI-AVEJONAS, Daniela ReginaOBJECTIVE: The aim of this study was to characterize the epidemiological profile of the population attending primary health care units in the western region of the city of Sao Paulo, Brazil, highlighting referred speech-language and hearing complaints. METHOD: This investigation was a cross-sectional observational study conducted in primary health care units. Household surveys were conducted and information was obtained from approximately 2602 individuals, including (but not limited to) data related to education, family income, health issues, access to public services and access to health services. The speech-language and hearing complaints were identified from specific questions. RESULTS: Our results revealed that the populations participating in the survey were heterogeneous in terms of their demographic and economic characteristics. The prevalence of referred speech-language and hearing complaints in this population was 10%, and only half the users of the public health system in the studied region who had complaints were monitored or received specific treatment. CONCLUSIONS: The results demonstrate the importance of using population surveys to identify speech-language and hearing complaints at the level of primary health care. Moreover, these findings highlight the need to reorganize the speech-language pathology and audiology service in the western region of Sao Paulo, as well as the need to improve the Family Health Strategy in areas that do not have a complete coverage, in order to expand and improve the territorial diagnostics and the speech-language pathology and audiology actions related to the prevention, identification, and rehabilitation of human communication disorders.
- Longitudinal evaluation of a hearing protector fit training program(2019) ASSUNCAO, Caio Henrique de Carvalho; TRABANCO, Julio Cesar; GOMES, Raquel Fornaziero; MOREIRA, Renata Rodrigues; SAMELLI, Alessandra GiannellaObjective: The present study evaluates a training program for fitting dyferent hearing protection devices (HPDs) based on personal attenuation rating (PAR) before, immediately after, and six months after training. Methods: A total of67 workers from a public university in the city of Sao Paulo, Brazil, were invited to participate in the measurement of PARs for foam and silicone protectors through the 3M (TM) E-A-Rfit Validation System. Two evaluations were performed for each protector at each sampling date: one after reading printed material (the package instructions) and another after being trained by an audiologist. The same procedures were repeated after six months. The final sample consisted of 30 individuals. AIVOVA was used for statistical analysis. Results: Larger PAR values were observed after training by the audiologist, and smaller values were observed after six months. Then, after re-training, the values increased again. There were no statistically significant differences in PAR among the HPDs tested. Even after the two training sessions, 23 to 27% of the subjects did not obtain adequate PAR values. Conclusion: These findings emphasize the need for continual worker training in the correct fit of earplug HPDs and the importance of longitudinal PAR monitoring. In addition, some workers, despite the training provided, did not adapt to the HPDs used. Therefore, it is essential that other protection methods and/or other HPD types are made available to these individuals.
