Métodos: 72 profissionais da voz com queixa vocal, encaminhados para reabilitação vocal por disfonia comportamental, foram acompanhados por seis sessões de terapia de voz. Os participantes foram divididos aleatoriamente em dois grupos. Um deles foi submetido ao PIRV e o outro, ao EFV. O material de fala analisado foi a vogal /ε/, gravada no módulo qualidade vocal do programa Voxmetria (CTS Informatica), para extração do DDF, nos momentos pré e pós-terapia. Os grupos foram comparados de acordo com o grau geral do desvio vocal, aspectos acústicos e com a distribuição das amostras vocais no DDF, em relação à área de normalidade, densidade, forma e localização nos quadrantes. Resultados: Houve diferença apenas quanto à densidade do registro do DDF no pós-terapia vocal, sendo que o grupo EFV apresentou registro concentrado no pósterapia quando comparado ao grupo PIRV. Apenas indivíduos do grupo PIRV apresentaram diferenças na avaliação perceptivo-auditiva pré e pós, sendo que mais indivíduos tiveram suas vozes avaliadas como Trabalho no 21º Congresso Brasileiro de Fonoaudiologia, ocorrido em apresentado Porto de Galinhas-PE, entre os dias 22 e 25 de setembro de 2013

Auditory feedback seems to be a crucial factor in the way the voice is produced and monitored. Evaluation of auditory processing using the Frequency Following Response (FFR) allows fine-grained neural processing to be objectively identified and might be a way of differentiating between those who sing in-tune and those who sing off-tune.The aim of this study was to analyse the FFR responses of people who can sing in-tune and compare them to those who sing off-tune. Material and methods: FFR responses were recorded in 37 adults who were assigned to one of two groups: (i) a control group (CG) consisting of 17 adults who could sing in-tune (ii) an experimental group (EG) consisting of 20 adults who sang off-tune. Results: There were statistically significant differences in the electro-physiological responses of the EG compared to the CG for the latencies of waves A, C, D, and F in the right ear. In contrast, FFR amplitude measurements did not seem to be a suitable parameter for identifying changes in the coding of speech sounds. Conclusions: FFR responses in the EG showed a different pattern from the CG group, with a number of longer latencies in the EG. However, FFR amplitude did not differ significantly between the groups.

Methods Observational, analytical, cross-sectional, ambispective study including prepubertal children with CH (n=100; study group, SG) and controls without CH ( n=100; control group, CG). Assessments included a speech language pathology interview, the phonological evaluation of the ABFW Child Language Test, medical data, and neuropsychological tests in the first three years of life. Results On treatment onset of the SG, the median chronological age of the participants was 18.0 days and 48.4% had total T4 <2.5 µg/dL (31.75 nmol/L). At the age of 7 years, children in the SG had higher rates of consonant cluster simplification and lower rates of complete phonological system compared to those in the CG. On analysis of combined age groups (4+5 and 6+7 years), the CG had a higher frequency of complete acquisition versus the SG. On multivariate analysis, thyroid agenesis, abnormal score...

Study Design. This is a cross-sectional, prospective, multicentric study. Methods. Two hundred ninety-eight male and female adults who are nonprofessional voice users volunteered to participate in the study. The participants answered an online survey and two self-assessment instruments: the Voice Symptom Scale (VoiSS) and the Short Self-Regulation Questionnaire (SSRQ). Individuals were classified into two groups according to VoiSS cutoff value: a vocally healthy group (total score of 15 points or lower) and a vocal symptoms group (16 points and above). The subscales of the VoiSS (impairment, emotional, and physical) were compared with the subscales of the SSRQ (goal setting and impulse control). Results. Subjects of the vocally healthy group scored differently from subjects with vocal symptoms both in goal setting and impulse control. The results from subjects with vocal symptoms are similar to individuals with addictive behaviors. A significant negative correlation was found between the SSRQ and the VoiSS scores, indicating a strong relationship between self-regulation and vocal symptoms. A relationship between impulsivity, lack of control, and difficulty in goal setting for specific behaviors was also noted. However, caution should be taken as this is an initial exploratory study using self-assessment questionnaires. Conclusions. Subjects with vocal symptoms have a lower level of self-regulation compared to those without vocal symptoms. As the number of vocal symptoms increased, the impulse control and goal setting scores decreased.

Methods: Forty-three men (mean age 42 years, range 19-69) and 145 women (mean age 34 years, range 18-68) were included. None of the subjects had received voice therapy or previous laryngeal surgery. A questionnaire, laryngeal and perceptual evaluations, aerodynamic and acoustic parameters, and the Dysphonia Severity Index (DSI) were used to determine vocal characteristics. Results: In 74% of the subjects, flexible laryngeal videostroboscopic evaluation revealed a vocal pathology, with vocal nodules and muscle tension dysphonia as the most frequently diagnosed pathologies. Vocal abuse/misuse was present in 65% of the subjects. A median DSI value of -0.4 and -0.8 was found in female and male patients, respectively. Aerodynamic and acoustic parameters and DSI scores were significantly different from normative d...

Design. This is a longitudinal quantitative study conducted in municipal schools. Method. We performed a data analysis of 469 teachers, reassessed 3 years after an initial study. The Voice Handicap Index was used to measure the impact of a probable voice problem with a cutoff value of 19 points. Mental disorder symptomatology was measured by the Self-Reporting Questionnaire (20 items), with a cutoff value of eight points. Bivariate analysis was conducted through Poisson regression to verify proportion differences in the occurrence of perceived voice disorders among the study's different categories of independent variables. The same technique of Poisson regression was used to assess risk factors for perceived voice disorder incidence in a specific hierarchic model. Results. The incidence of a perceived voice disorder was 17.1%. Teachers who lectured in fourth grade and below presented a risk of 20% less than those who lectured from the fifth grade up (P = 0.046). Teachers who reported taking a leave of absence because of their voice had a 32% more chance of a probable perceived voice disorder (P = 0.024). Teachers who presented a common mental disorder had twice the risk of perceived voice disorder (P > 0.001). Conclusions. This study concluded that teachers presented a higher risk of developing a perceived voice disorder when they have the following features: lectured from fifth grade up, have gone on leave because of their voice, and showed behavior indicative of common mental disorder.

Study Design. This is a cross-sectional study. Methods. The sample comprised 526 volunteer amateur choristers-186 male and 340 female-(mean age of 42.07 years) from different choirs in the region of São Paulo. Three questionnaires were used: the Voice Symptom Scale (VoiSS), the Modern Singing Handicap Index (MSHI), and the Generalized Anxiety Disorder 7-item (GAD-7) scale. Results. The mean total score obtained on the VoiSS was 17.57, which is almost two points higher than the protocol's passing score (16). The choristers who scored higher or equal to 16 points (51.5%, n = 271)-considered at vocal risk-and the group who scored less than 16 points (48.5%, n = 255)-healthy group-were analyzed separately. The risk group presented a mean total score of 26.34 on the VoiSS and 20.97 on the MSHI, with higher deviation on the impairment subscale, followed by the disability and handicap subscales, along with mild anxiety. The healthy group presented a mean total score of 8.27 on the VoiSS and 6.11 on the MSHI, also with higher deviation in the impairment subscale, followed by disability and handicap, and a minimum level of anxiety. Conclusion. Even in leisure activities, vocal care is necessary for the correct use of the singing voice, which demands individual adaptations. The use of protocols for voice symptoms and singing handicap has revealed the possibility of amateur choristers to present vocal risk.

However, missing in this group, are newly graduated students, who do not belong to any continuous education program, focus of great professional concerns. Participating in congresses can provide three benefits: immediate intensive update, enlargement of the network of relationships, and a reflection about our position in relation to our colleagues. We can even think that with all the available information online, the congresses would lose their importance, but that is not what we observe. Moreover, congresses are where we identify new leadership and understand the ways of our profession. If I want to study, I prefer to stay at home accessing papers, which is what I do almost daily; nevertheless, if I want to understand what is happening to my career, to the group I belong, and to my profession, then I go to a congress. The congress is the mirror in which I see myself through others. Congresses have changed; they are more dynamic and have a faster pace. Besides, in my case specifically, as a voice expert and a consultant in communicative competence, it is during Speech-Language Pathology and Audiology congresses that I get updated regarding other specialization areas. We are, above all, speech-language pathologists and audiologists, and we cannot lose sight of the whole subject, which is a great risk if we only participate in meetings of our areas of specific interest. Currently, I hold an honorable position as president of the SBFa, which allows me to talk daily to colleagues from all over Brazil. There is a group of professionals that is aligned with the society, who compliments, critics and and offers help, and another group that is distant, and, sometimes, even aggressive in their positions. The colleagues from the first group are enthusiasts, they get annoyed when something doesn't work in a congress, they complain, demand and also identify and compliment changes achieved in the last ten years; meanwhile, the colleagues from the second group either insistently reiterate that they are against the society or complain that the congress is expensive and that the profession is not doing well. I do not have any scientific study to prove my observation, but I notice that the ones that do not go to scientific meetings seem to be more dissatisfied with their professional choice, and to have less strength to fight for a good career. I wish everybody would take part in our congresses, and would complain being a part of the society, and would criticized the scientific production during the discussions that follow the presentations, this way we could get stronger, help our newly graduated colleagues and really reduce the fees of such a big event. The 2011 congress has the motto COMUNICATION AS A RIGHT FOR ALL, and it presents an intense and broad schedule that values interdisciplinarity and international knowledge. In the 19 th Brazilian and 8 th International Speech-language Pathology and Audiology Congress, to be carried out from October 30 th to November 2 nd at the WTC-Sheraton Convention Center, in São Paulo, there are going to be developed six Conferences, 16 Symposiums (11 Interdepartmental meetings, one from the Education Committee and five Update meetings), 12 Workshops (six research and six practice workshops), 18 Round Tables for specific areas, 30 Oral Presentation Sessions, eight Poster Presentation Sessions (Coffee-break with Science), six Instructional Courses, four Update Panels, four Technical-Scientific Meetings, three Undergraduate and Graduate (lato and stricto sensu) Work Group Meetings, and three Career Interviews. This program, carefully prepared by the indefatigable scientific directors, Letícia Mansur and Jacy Perissinoto, has the aim to reflect our reality and to cast powerful ties towards the future, just as the Estaiada Bridge, that symbolizes this congress. The importance of the event is due to the fact that is the greatest scientific meeting of the Brazilian Speech-Language Pathology and Audiology, and second in the world, regarding number of participants. I highlight, in the present year, the participation of colleagues representing the academic and organizational realms of our profession: we will have the presence of the ex-president of the International Association of Logopedics and Phoniatrics-IALP and of the American Speech-Language and Hearing Association-ASHA, Dolores viii Battle, who is going to talk about Global Aspects of Speech-Language Pathology and Audiology; the current ASHA's president, Paul Rao, who is going to share his experience with Rehabilitation of Speech Disorders due to Traumatic Brain Injury; the director of the International Society of Audiology-ISA, George Mencher, who is going to present the State of Art of Audiology; the professor Kristiane Van Lierde, from the University of Ghent, Belgium, who is going to bring a review about vocal rehabilitation in functional dysphonia; and Rafael Bernal Castro, director of the Sociedad Iberoamericana de Informacion Cientifica (SIIC), who is going to discuss the Scientific Publication Panorama in the Latin America with editors-in-chief of national journals. In addition to these specific topics, the congress will have the honorable contribution of colleagues from other areas, who will bring us essential information for a more humanistic education, such as Suely Dalari, who will address the issue of Health as a Right, and Sonia Brucki, who is going to talk about Cognitive Reserve and Language. The career interviews, profoundly inspiring, will have the contributions of Lemmieta MacNelly, who is going to tell the story of the transformation of ASHA into a strong professional organization; of Cláudia Cotes, who is going to share with us an enthusiastic report about the challenges of leading the Non-Governamental Organization "Vez da Voz"; and of Alex Perissinoto, who is going to reason about the construction of a Professional Image. Regardless, all of these will only make sense if we have an expressive number of participants, in order for us to reinforce this network of relationships that is essential for professional development and crucial during moments of crisis.

Study Design. This is a cross-sectional study. Methods. The sample comprised 526 volunteer amateur choristers-186 male and 340 female-(mean age of 42.07 years) from different choirs in the region of São Paulo. Three questionnaires were used: the Voice Symptom Scale (VoiSS), the Modern Singing Handicap Index (MSHI), and the Generalized Anxiety Disorder 7-item (GAD-7) scale. Results. The mean total score obtained on the VoiSS was 17.57, which is almost two points higher than the protocol's passing score (16). The choristers who scored higher or equal to 16 points (51.5%, n = 271)-considered at vocal risk-and the group who scored less than 16 points (48.5%, n = 255)-healthy group-were analyzed separately. The risk group presented a mean total score of 26.34 on the VoiSS and 20.97 on the MSHI, with higher deviation on the impairment subscale, followed by the disability and handicap subscales, along with mild anxiety. The healthy group presented a mean total score of 8.27 on the VoiSS and 6.11 on the MSHI, also with higher deviation in the impairment subscale, followed by disability and handicap, and a minimum level of anxiety. Conclusion. Even in leisure activities, vocal care is necessary for the correct use of the singing voice, which demands individual adaptations. The use of protocols for voice symptoms and singing handicap has revealed the possibility of amateur choristers to present vocal risk.

Por iniciativa da administração central, criou-se um grupo técnico para elaborar critérios de temporalidade das amostras biológicas e dos produtos armazenados frente à legislação e às necessidades deste repositório institucional. Foram definidos os diversos tipos de amostras e, para cada modalidade, foram relacionados o estado físico, a finalidade – rotina ou pesquisa –, e as condições de armazenamento. Formulários específicos referentes às amostras ou produtos foram preenchidos pelos profissionais das d...

However, missing in this group, are newly graduated students, who do not belong to any continuous education program, focus of great professional concerns. Participating in congresses can provide three benefits: immediate intensive update, enlargement of the network of relationships, and a reflection about our position in relation to our colleagues. We can even think that with all the available information online, the congresses would lose their importance, but that is not what we observe. Moreover, congresses are where we identify new leadership and understand the ways of our profession. If I want to study, I prefer to stay at home accessing papers, which is what I do almost daily; nevertheless, if I want to understand what is happening to my career, to the group I belong, and to my profession, then I go to a congress. The congress is the mirror in which I see myself through others. Congresses have changed; they are more dynamic and have a faster pace. Besides, in my case specifically, as a voice expert and a consultant in communicative competence, it is during Speech-Language Pathology and Audiology congresses that I get updated regarding other specialization areas. We are, above all, speech-language pathologists and audiologists, and we cannot lose sight of the whole subject, which is a great risk if we only participate in meetings of our areas of specific interest. Currently, I hold an honorable position as president of the SBFa, which allows me to talk daily to colleagues from all over Brazil. There is a group of professionals that is aligned with the society, who compliments, critics and and offers help, and another group that is distant, and, sometimes, even aggressive in their positions. The colleagues from the first group are enthusiasts, they get annoyed when something doesn't work in a congress, they complain, demand and also identify and compliment changes achieved in the last ten years; meanwhile, the colleagues from the second group either insistently reiterate that they are against the society or complain that the congress is expensive and that the profession is not doing well. I do not have any scientific study to prove my observation, but I notice that the ones that do not go to scientific meetings seem to be more dissatisfied with their professional choice, and to have less strength to fight for a good career. I wish everybody would take part in our congresses, and would complain being a part of the society, and would criticized the scientific production during the discussions that follow the presentations, this way we could get stronger, help our newly graduated colleagues and really reduce the fees of such a big event. The 2011 congress has the motto COMUNICATION AS A RIGHT FOR ALL, and it presents an intense and broad schedule that values interdisciplinarity and international knowledge. In the 19 th Brazilian and 8 th International Speech-language Pathology and Audiology Congress, to be carried out from October 30 th to November 2 nd at the WTC-Sheraton Convention Center, in São Paulo, there are going to be developed six Conferences, 16 Symposiums (11 Interdepartmental meetings, one from the Education Committee and five Update meetings), 12 Workshops (six research and six practice workshops), 18 Round Tables for specific areas, 30 Oral Presentation Sessions, eight Poster Presentation Sessions (Coffee-break with Science), six Instructional Courses, four Update Panels, four Technical-Scientific Meetings, three Undergraduate and Graduate (lato and stricto sensu) Work Group Meetings, and three Career Interviews. This program, carefully prepared by the indefatigable scientific directors, Letícia Mansur and Jacy Perissinoto, has the aim to reflect our reality and to cast powerful ties towards the future, just as the Estaiada Bridge, that symbolizes this congress. The importance of the event is due to the fact that is the greatest scientific meeting of the Brazilian Speech-Language Pathology and Audiology, and second in the world, regarding number of participants. I highlight, in the present year, the participation of colleagues representing the academic and organizational realms of our profession: we will have the presence of the ex-president of the International Association of Logopedics and Phoniatrics-IALP and of the American Speech-Language and Hearing Association-ASHA, Dolores viii Battle, who is going to talk about Global Aspects of Speech-Language Pathology and Audiology; the current ASHA's president, Paul Rao, who is going to share his experience with Rehabilitation of Speech Disorders due to Traumatic Brain Injury; the director of the International Society of Audiology-ISA, George Mencher, who is going to present the State of Art of Audiology; the professor Kristiane Van Lierde, from the University of Ghent, Belgium, who is going to bring a review about vocal rehabilitation in functional dysphonia; and Rafael Bernal Castro, director of the Sociedad Iberoamericana de Informacion Cientifica (SIIC), who is going to discuss the Scientific Publication Panorama in the Latin America with editors-in-chief of national journals. In addition to these specific topics, the congress will have the honorable contribution of colleagues from other areas, who will bring us essential information for a more humanistic education, such as Suely Dalari, who will address the issue of Health as a Right, and Sonia Brucki, who is going to talk about Cognitive Reserve and Language. The career interviews, profoundly inspiring, will have the contributions of Lemmieta MacNelly, who is going to tell the story of the transformation of ASHA into a strong professional organization; of Cláudia Cotes, who is going to share with us an enthusiastic report about the challenges of leading the Non-Governamental Organization "Vez da Voz"; and of Alex Perissinoto, who is going to reason about the construction of a Professional Image. Regardless, all of these will only make sense if we have an expressive number of participants, in order for us to reinforce this network of relationships that is essential for professional development and crucial during moments of crisis.
