Programa de saúde vocal para educadores: ações e resultados

TEMA: a voz do professor tem sido foco de estudos nas últimas duas décadas devido à alta ocorrência de alterações vocais nesta classe profissional, assim, reforçou-se a necessidade dos professores participarem de ações para garantir saúde vocal. Poucos são os estudos na literatura que descrevem programas e seus resultados. PROCEDIMENTOS: Descrever um Programa de Saúde Vocal desenvolvido no período 2002 a 2005, para educadores de ensino público (infantil e fundamental) do interior do Estado de São Paulo, composto por grupos básicos de voz oferecendo conhecimento teórico prático de cuidados vocais, com triagem da qualidade da voz dos participantes; grupos avançados buscando reorganização dos processos de fonação e do uso vocal em sala de aula. RESULTADOS: em média 56% dos educadores inscritos frequentaram as ações; 62,9% das vozes apresentavam distúrbios na triagem vocal com maioria em grau discreto; no início dos grupos avançados 100% dos educadores participantes referiram mais de 3 sintomas associados ao uso vocal, e após, somente 45% deles ainda de 4 a 13 sintomas; os dados de autopercepção vocal revelaram baixos escores de impacto da voz nas atividades profissionais. CONCLUSÃO: a descrição revelou a necessidade de ajustes constantes do programa para alcançar seus objetivos. A baixa participação às ações pode estar relacionada à presença de impacto discreto da voz nas atividades profissionais, fato a ser mais bem investigado no futuro, e o benefício constatado objetivamente da participação dos educadores nos grupos avançados de voz foi a diminuição na quantidade de sintomas vocais.

Morphometric and histochemical study of the human vocal muscle

The present study was conducted on vocal muscles removed at autopsy Rom adult individuals (10 men and 8 women, aes ranging from 48 to 78 years) with no laryngeal disease. Histologic analysis was performed with hematoxylin and eosin staining, and histochemical analysis was performed by nicotinamide-adenine-dinucleotide tetrazolium reductase, succinate dehydrogenase, and acid and alkaline myofibrillar adenosine triphosphatase reactions. The histochemical reactions showed that the muscle consists of slow-twitch oxidative (SO), fast-twitch glycolytic (FG), and fast-twitch glycolytic oxidative (FOG) fibers distributed in mosaic form. The frequencies of SO, FOG, and FG fibers were 40.50%, 54.75%, and 4.75%, respectively. The higher frequency of SO and FOG oxidative fibers characterizes the muscle as having aerobic metabolism, resistance to fatigue, and fast contraction. The mean minimum diameters were 31.37 mu m for SO fibers and 36.46 mu m for FOG and FG fibers.

Laryngeal electromyography: Contribution to vocal fold immobility diagnosis

Laryngeal Electromyography (LEMG) is a diagnostic test commonly used in patients with vocal fold movement disorder The aim of this study is to describe LEMG in patients with vocalfold immobility. A total of 55 dysphonic patients with vocal fold immobility diagnosed by laryngeal endoscopy were grouped according to probable clinical cause: 1) unknown; 2) traumatic; or 3) tumoral compression. They were submitted to LEMG by percutaneous insertion of concentric needle electrode. LEMG was conclusive in all patients and showed a majority with peripheral nerve injury. LEMG diagnosed peripheral nerve damage in 25 group 1, 12 group 2, and 11 group 3 patients. LEMG was normal in 4 patients, suggesting cricoarytenoid joint fixation. Central nervous system disorders was suggested in 2 and myopathic pattern in 1. As the major cause of vocal fold immobility is peripheral nerve damage, LEMG is an important test to confirm diagnosis.

The physiological changes associated with the age advancing can make pharmacokinetic and pharmacodynamic alterations. The cognitive decline, physical limitations and associate chronic pathology affect the medications appropriately use ability. Aims: Based in a literature review, appoint the main pharmacological groups prescribed to the elderly and the drug-drug interaction risks. Conclusion: The most of elderly use continually at least 3 medicines, the most prescribed are to cardiovascular and psychic diseases treatment.

Entrenamiento continuo vs. interválico corriendo en piscina profunda: Efectos sobre la salud de las mujeres obesas

Objectives. To search intermittent and continous trainning (IT and CT, respectively) effects through deep water running for the control and prevention of excessive body fat accumulation and improvement of quality of life. Methods. Experimental study composed by 30 women, aged between 34 to 58 years old, during 12 weeks, three sessions per week, 47 minutes each. Body composition, cardiorespiratory condition and Quality of Life by WHOQOL-Brief were considered. Student's and Wilcoxon's non parametric tests were applied at 5% significance level. Results. With the only exception for social domain of quality of life, all investigated variables revealed improvement in both groups for IT in comparison to CT. Conclusion. Deep water running contributes to body fat reduction, physical fitness evolution and improvement of WHOQOL-Brief domains, regardless of the trainning type conducted. © 2012 Revista Andaluza de Medicina del Deporte.

Clinical diagnosis and histological analysis of vocal nodules and polyps

Recent studies emphasize the importance of the clinical-histology correlation in laryngeal pathologies. Objective: To compare the ENT diagnosis with the pathology diagnosis one of 132 surgical specimens, from 119 patients with vocal nodules and polyps. Method: Retrospective study. We investigated the paraffin blocks corresponding to the lesions of the operated patients. We made new histology cross-sections, totaling 396 new slides, divided into three groups: hematoxylin and eosin, Gomori trichrome and PAS. We analyzed the following histological parameters: epithelium, lamina propria, basement membrane, vascular changes. We compared the laryngological and pathological diagnoses, and we did the statistical analysis, checking the predominant histological aspects in each lesion. Results: There was an agreement between the clinical and pathological diagnoses in 123 (93.18%) of 132 lesions analyzed (42.42% nodules and 50.76% polyps). In the histological parameters we found: epithelial changes such as nodules hyperplasia (82.14%) and polyp atrophy (31.34%). Lamina propria: edema in polyps (71.43%), fibrosis in the nodules (57.14%). Basement membrane: thickened nodules (100%), thin/no change in polyps (100%). There was a predominance of vascular changes in the polyps. Conclusion: We found a high correlation between the ENT diagnosis and the pathology report. Histopathologically, the nodules presented with predominantly epithelial changes, lamina propria and basement membrane fibrosis, while the polyps by changes strictly on the lamina propria and vascular aspects.

Perceptual and acoustic parameters of vocal nodules in children

Vocal nodules constitute the major cause of dysphonia during childhood. Auditory-perceptual and acoustic vocal analyses have been used to differentiate vocal nodules from normal voice in children.Purpose: To study the value of auditory-perceptual and acoustic vocal analyses in assessments of children with nodules.Design: Diagnostic test study.Patients and interventions: A comparative study was carried out including 100 children with videolaryngoscopic diagnosis of vocal nodules (nodule group-NG); and 100 children without vocal symptoms and with normal videolaryngoscopic exams (control group-CG). The age range of both groups was between 4 and 11 years. All children underwent auditory-perceptual vocal analyses (GRBASI scale); maximum phonation time and s/z ratio were calculated, and acoustic vocal analysis (MDVP software) were carried out.Results: There was no difference in the values of maximum phonation time and s/z ratio between groups. Auditory-perceptual analysis indicated greater compromising of voice parameters for NG, compared to CG: G (79 versus 24), R (53 versus 3), B (67 versus 23) and S (35 versus 1). The values of acoustic parameters jitter, PPQ shimmer, APQ, NHR and SPI were higher for NG for CG. The parameter f0 did not differ between groups.Conclusion: Compromising of auditory-perceptual (G, R, B and S) and acoustic vocal parameters (jitter, PPQ shimmer, APQ, NHR and SPI) was greater for children with nodules than for those of the control group, which makes them important methods for assessing child dysphonia.

Aquecimento e Desaquecimento Vocal em Estudantes de Pedagogia

Introduction: the voice is one of the main features of interaction between teacher and student. As teachers, future teachers are also risk population for the development of dysphonia and may be subject to protective intervention. Purpose: to evaluate the effect of a vocal warm-up and cool-down procedure at Pedagogy students. Method: A quasi-experimental study, pre-posttest without a control group, with fourteen Pedagogy students at a public university, participants of a short course. The analysis was performed by a self-assessment visual analogue scale of 10 cm, considering aspects related to the body and voice. The protocol was implemented in three steps: pre-test, post warm-up and post cool-down, and it was calculated the averages of the variables of discomfort and compared the measurements before and after performing each procedure. It was used the the Wilcoxon signed-rank statiscal test, adopting a significance level of 5%. Results: there was less discomfort with statistical significance after the vocal warm-up (p=0.002) and cool-down (p=0.001), with greater magnitude in both aspects related to voice. Conclusions: The vocal warm-up and cool-down have positive effects on the perception of students and should be taught to future teachers in order to prevent vocal disorders. The vocal cool-down, poorly researched, should not be passed over vocal health practices since its purpose showed obvious improvement in the investigated group.
