- Earmuff efficacy in the workplace using F-MIRE - a case report(2018) GOMES, Raquel Fornaziero; SAMELLI, Alessandra Giannella; BISTAFA, Sylvio R.Purpose. To determine the field efficacy of an earmuff used by the employees of a private company. Methods. Measurements were performed using a double-channel noise dosimeter. Noise levels collected in one-third-octave bands were corrected with the frequency response for diffuse sound field and attenuation was compared with values provided by the manufacturer of the hearing protection device (HPD). Results. Comparisons between the corrected noise reduction and the attenuation provided by the manufacturer of the HPD show no statistically significant differences in attenuation for most frequency bands, with higher mean values for the observed corrected noise reduction. However, despite the fact that the field attenuation values are above those obtained in the laboratory, when individual attenuation values were compared with expected attenuation values it was found that the employees have below-expected noise attenuation in all frequency bands. Conclusions. The fact that over 60% of the employees had frequency band attenuations below that expected for most frequency bands underscores the need for individual assessment of attenuation provided by the HPD in the workplace, to assess whether the HPD is functional and what provisions should be implemented in a specific workplace.
- Effects of diabetes mellitus and systemic arterial hypertension on elderly patients' hearing(2018) ROLIM, Laurie Penha; SAMELLI, Alessandra Giannella; MOREIRA, Renata Rodrigues; MATAS, Carla Gentile; SANTOS, Itamar de Souza; BENSENOR, Isabela Martins; LOTUFO, Paulo AndradeIntroduction: Chronic diseases can act as an accelerating factor in the auditory system degeneration. Studies on the association between presbycusis and diabetes mellitus and systemic arterial hypertension have shown controversial conclusions. Objective: To compare the initial audiometry (A1) with a subsequent audiometry (A2) performed after a 3 to 4-year interval in a population of elderly patients with diabetes mellitus and/or systemic arterial hypertension, to verify whether hearing loss in these groups is more accelerated when compared to controls without these clinical conditions. Methods: 100 elderly individuals participated in this study. For the auditory threshold assessment, a previous complete audiological evaluation (A1) and a new audiological evaluation (A2) performed 3-4 years after the first one was utilized. The participants were divided into four groups: 20 individuals in the diabetes mellitus group, 20 individuals in the systemic arterial hypertension group, 20 individuals in the diabetes mellitus/systemic arterial hypertension group and 40 individuals in the control group, matching them with each study group, according to age and gender. ANOVA and Kruskal-Wallis statistical tests were used, with a significance level set at 0.05. Results: When comparing the mean annual increase in the auditory thresholds of the A1 with the A2 assessment, considering each study group and its respective control, it can be observed that there was no statistically significant difference for any of the frequencies for the diabetes mellitus group; for the systemic arterial hypertension group, significant differences were observed after 4 kHz. For the diabetes mellitus and systemic arterial hypertension group, significant differences were observed at the frequencies of 500, 2 kHz, 3 kHz and 8 kHz. Conclusion: It was observed that the systemic arterial hypertension group showed the greatest decrease in auditory thresholds in the studied segment when compared to the other groups, suggesting that among the three studied conditions, hypertension seems to have the greatest influence on hearing.

- Atenção Básica como ordenadora do cuidado ao bebê de risco para alterações do neurodesenvolvimento(2018) MOLINI-AVEJONAS, Daniela Regina; RONDON-MELO, Silmara; BATISTA, Estela Ramos; SOUZA, Amanda Calsolari de; DIAS, Daniela Cardilli; SAMELLI, Alessandra GianellaABSTRACT Purpose Characterize infants at risk of neurodevelopmental disorders according to sociodemographic and health profiles and describe their monitoring in Basic Health Units (UBS) under different management models. Methods Data were collected from medical records of infants at risk of neurodevelopmental disorders in the west region of the city of Sao Paulo from August 2013 to February 2014 (phase 1 – characterization; phase 2 – monitoring). Results Of the 225 individuals assessed in the first phase of the study, 51.1% were female and 7.11% were twins. Adolescent (45.2%), brown (50.56%), single (46.09%), complete primary education (47.60%) mothers were predominant. The mean number of prenatal visits was 7.12. Most mothers had vaginal delivery (62.22%) at mean gestational age of 37.05 weeks. Mean Apgar scores at the 1st and 5th minutes were 7.13 and 8.80, respectively. Mean weight at birth was 2597.21g., with 50.22% of newborns weighting ≤2500g. In its second phase, the study describes and compares the follow-up of 55 infants according to the UBS management model: 28 in UBS/“Estratégia Saúde da Família” (UBS/ESF) and 27 in traditional UBS (UBS/T). UBS/ESF presented higher mean of consultations (p=0.006). Longer interval between consultations was observed at UBS/T. No records of development milestones were found in 56% of the sample. Growth measures were better registered at UBS/ESF. In both management models, the number of consultations was smaller and the interval between them was shorter than those recommended by the Brazilian Ministry of Health. Conclusion According to the recommended guidelines of the “Rede Cegonha” public policy, gaps in the monitoring of infants at risk of neurodevelopmental disorders are still observed.
- Effects of a vestibular rehabilitation program on workers in the working environment: a pilot study(2018) LONGO, Isadora Altero; NUNES, Ariane Diane Morais; ROCHA, Clayton Henrique; BRANCO, Fabiana Mara; MOREIRA, Renata Rodrigues; NEVES-LOBO, Ivone Ferreira; CASAROTTO, Raquel Aparecida; SAMELLI, Alessandra GiannellaABSTRACT Objective: to verify the effect of a vestibular rehabilitation program on workers with dizziness from the Division of Nutrition and Dietetics at a University Hospital. Methods: a total of 13 employees between 42 and 65 years of age participated, of whom, 1 was male, and 12, females. They were evaluated before and after the vestibular rehabilitation program using the Dizziness Handicap Inventory, Work Ability Index and Visual Analog Scale. The program was conducted in groups at the workplace. Statistical analysis was performed using the analysis of variance test for paired factors and the chi-square test. Results: in the pre- and post-vestibular rehabilitation comparison, significant differences were found in the Dizziness Handicap Inventory and Visual Analogue Scale scores. In the qualitative analysis of the Work Ability Index, an increase was observed in the number of workers who considered their ability to work to have improved. Conclusion: vestibular rehabilitation conducted in groups and in the working environment was effective in improving dizziness complaint in workers at the Division of Nutrition and Dietetics. It is believed that the positive experience of this program may be extended to other areas.
- The Study of Attenuation Levels and the Comfort of Earplugs(2018) SAMELLI, Alessandra G.; GOMES, Raquel F.; CHAMMAS, Tiago V.; SILVA, Barbara G.; MOREIRA, Renata R.; FIORINI, Ana C.Introduction: This study aimed to analyze and compare four different types of earplugs, divided into premolded plugs and foam plug models, in relation to the level of attenuation, comfort, and the size of the external acoustic meatus (EAM) in an attempt to identify how these variables influence the choice of specific hearing protection devices (HPDs). Materials and Methods: A cross-sectional observational study was performed in a sample of 49 participants, oriented toward the ideal placement of four HPDs, two premolded and two foam plugs (3M (TM)). The procedures included otoscopy, EAM diameter measurement using an otometer, EAM volume measurement via an acoustic impedance test, and the obtainment of the bilateral personal attenuation rating (PAR) for each HPD using the E-A-Rfit (TM) Validation System (3M (TM)). The Bipolar Comfort Rating Scale (BCRS) instrument was applied twice for each individual: once after the evaluations with the premolded HPDs and again after the evaluations with the foam plug HPDs. Then, each participant was asked which was his/her favorite protector. Results: The volume of the EAM was not directly related to the diameter of the EAM. The attenuation did not interfere with the HPD preference, and the PAR of the foam plug was significantly higher regardless of the preferred HPD. Regarding the BCRS, the variables ""Placement,"" ""Complexity,"" and ""Occlusion Effect"" had higher scores for premolded HPDs and had a direct relationship with the type of preferred HPD. Conclusion: Attention to the use of HPDs should be personalized, taking into account the needs of each individual, considering not only the attenuation, but also the user's reported well-being.
- Audiological and electrophysiological alterations in HIV-infected individuals subjected or not to antiretroviral therapy(2018) MATAS, Carla Gentile; SAMELLI, Alessandra Giannella; MAGLIARO, Fernanda Cristina Leite; SEGURADO, AluisioIntroduction: The Human Immunodeficiency Virus (HIV) and infections related to it can affect multiple sites in the hearing system. The use of High Activity Anti-Retroviral Therapy (HAART) can cause side effects such as ototoxicity. Thus, no consistent patterns of hearing impairment in adults with Human Immunodeficiency Virus / Acquired Immune Deficiency Syndrome have been established, and the problems that affect the hearing system of this population warrant further research. Objectives: This study aimed to compare the audiological and electrophysiological data of Human Immunodeficiency Virus-positive patients with and without Acquired Immune Deficiency Syndrome, who were receiving High Activity Anti-Retroviral Therapy, to healthy individuals. Methods: It was a cross-sectional study conducted with 71 subjects (30-48 years old), divided into groups: Research Group I: 16 Human Immunodeficiency Virus-positive individuals without Acquired Immunodeficiency Syndrome (not receiving antiretroviral treatment); Research Group II: 25 Human Immunodeficiency Virus-positive individuals with Acquired Immunodeficiency Syndrome (receiving antiretroviral treatment); Control Group: 30 healthy subjects. All individuals were tested by pure-tone air conduction thresholds at 0.25-8 kHz, extended high frequencies at 9-20 kHz, electrophysiological tests (Auditory Brainstem Response, Middle Latency Responses, Cognitive Potential). Results: Research Group I and Research Group II had higher hearing thresholds in both conventional and high frequency audiometry when compared to the control group, prolonged latency of waves I, III, V and interpeak I-V in Auditory Brainstem Response and prolonged latency of P300 Cognitive Potential. Regarding Middle Latency Responses, there was a decrease in the amplitude of the Pa wave of Research Group II compared to the Research Group I. Conclusions: Both groups with Human Immunodeficiency Virus had higher hearing thresholds when compared to healthy individuals (group exposed to antiretroviral treatment showed the worst hearing threshold) and seemed to have lower neuroelectric transmission speed along the auditory pathway in the brainstem, subcortical and cortical regions.
