Estudo transversal realizado em nove escolas estaduais de Campinas e Sao Jose do Rio Pardo, com 258 professores com o objetivo de caracterizar o perfil sociodemografico, estilos de vida, condicoes de saude e de trabalho. A amostra foi composta por mulheres (81,8%) e homens (18,2%), sendo casados (60,8%), com media de idade de 41,4 anos (DP 9,2), que realizavam atividade fisica (56,6%), lazer (93,4%) e tarefas domesticas (88,4%). Quanto a saude, 20,9% nao dormiam bem a noite; 82,1% possuiam doenca com diagnostico medico: musculo-esqueletica e respiratoria (27,1%); acidentes e doencas digestivas (22,1%) e transtornos mentais (20,9%). Tais doencas estavam relacionadas aos riscos relatados: movimentos repetitivos, presenca de poeira de giz, trabalho estressante, longas jornadas, atividade em mais de uma escola e baixa remuneracao. Concluiu-se que os professores eram expostos a riscos nas escolas e que medidas de promocao a saude e prevencao deveriam ser tomadas pelos governantes.

Purpose of review The current article reviews recent literature examining occupational voice use and occupational voice disorders (January 2018-July 2019). Recent findings Our understanding of the prevalence of voice disorders and work-related vocal use, vocal load and vocal ergonomics (environmental and person influences) across different occupations is continuing to build. There is encouraging evidence for the value of intervention programs for occupational voice users, particularly of late with performers, teachers and telemarketers. Education and prevention programs are emerging for other 'at risk' occupations. Summary Occupational health and workforce legislation does not adequately acknowledge and guide educational, preventive and intervention approaches to occupational voice disorders. Voice disorders are prevalent in certain occupations and there is an urgent need for research to support occupational voice health and safety risk measurement, prevention and intervention. Large population-based studies are required with a focus on the health and economic burden of occupational voice disorders.

Occupational voice is a work in progress: active risk management, habilitation and rehabilitation

PURPOSE: To analyze the intra- and inter-rater agreement for visual analog scale and numerical scale in task of sustained vowel and to determine numerical cutoff points to visual analog scale corresponding to the degrees of the numeric scale. METHODS: We selected 205 samples of the usual task of the sustained vowel /a/. Six voice specialists rated the overall degree of vocal deviation, first by visual analog scale and, after two days, by the numeric scale. The results obtained by both scales were compared and the intra- and inter-rater agreement, the correlation between the scales, and the estimated cutoff points using the intraclass correlation and concordance Kappa coefficients, the Spearman coefficient, and analysis of variance, and the values of sensitivity and specificity were analyzed. RESULTS: A strong correlation was observed between the scales. The following numerical cutoff values were found for visual analog scale corresponding to the numerical scale: neutral (degree zero) - 0 to 34 mm; mild (degree one) - 34.1 to 51 mm; moderate (degree two) - 51.1 to 63.5 mm; intense (degree three) - 63.6 to 77.5 mm; and extreme (degree four) - above 77.5 mm. CONCLUSION: The visual analog scale and numerical scale showed a strong correlation, being observed the greater intra- and inter-rater agreement in visual analog scale. Numerical cutoff values for visual analog scale were found. This correlation enables the comparison between the results found in the evaluation of the overall degree of vocal deviation by both scales, which are widely used in research and in the clinical speech therapy routine.

Auditory-perceptual evaluation of the degree of vocal deviation: correlation between the Visual Analogue Scale and Numerical Scale

Laryngopharyngeal reflux is a prevalent, not well-understood disease affecting a high proportion of patients who seek laryngology consultation. The objective of this prospective case series is to explore the subjective and objective voice modifications in Laryngopharyngeal reflux (LPR), especially the usefulness of acoustic parameters as treatment outcomes, and to better understand the pathophysiological mechanisms underlying the development of voice disorder. Forty-one patients with a reflux finding score (RFS) > 7 and a reflux symptom index (RSI) > 13 were enrolled and treated with pantoprazole 20 mg twice daily for three months. RSI, RFS, Voice Handicap Index (VHI), and Grade, Roughness, Breathiness, Asthenia, Strain and Instability (GRBASI) were assessed at baseline and after three months post-therapy. Acoustic parameters were measured by selecting the most stable interval of the vowel /a/. A study of correlations between acoustic measurements and laryngoscopic signs was conducted in patients with roughness. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS). Significant improvement in RSI, RFS, VHI, jitter, percent jitter, relative average perturbation (RAP), shimmer, percent shimmer, and amplitude perturbation quotient (APQ) was found at 3 months of treatment (p < .05). A correlation analysis revealed significant correlations between the grade of dysphonia, breathiness, asthenia, instability and jitter, percent jitter, RAP, shimmer, percent shimmer and APQ. In dividing our cohort into two groups of patients according to the presence of roughness, shimmer, percent shimmer and APQ significantly improved in patients with roughness, but no positive correlation was found between acoustic parameters and laryngoscopic signs. Acoustic parameters can help to better understand voice disorders in LPR and can be used as treatment outcomes in patients with roughness.
