[Ab] Resumo:Child dysphonia is a frequent pathological situation which concerns 6 to 38 percent of a school attending population. Thus it demands a specific and adapted treatment. Because of its direct consequences on social, family and school lives, parents often seek advice from a speech specialist. This study focuses on the specificities of those individuals having diagnosed child dysphonia, as well as the treatment which can be given to them. Our work covers a period of twenty years of comparative studies. We have read through dr Coulombeau's files, from 2005 to 2011, and we have made up a series of questions addressed to the speech therapists having speech impaired children in their practice. We have cross-examined these data with those of Dr Cornut's, covering a period of seven years (1985-1991). The qualitative and quantitative studies which have been carried out enabled us to highlight the fact there has been a constant background of child dysphonia and an evolution in the offered treatments. Indeed, we have realised that the number of individuals having diagnosed child dysphonia are less and less operated on. In the same time people tend to ignore the offered treatments. Though the follow-ups to a prior visit at a speech therapist have decreased for twenty years, it still remains the most common treatment. Our analysis does not focus on the effects of the given treatments on a long term basis. It thus appears that a study consisting in analysing the development of these children through adulthood would be greatly accurate.

[Ab] Resumo:The article is a brief review of publications devoted to the problem of persistent dysphonia. The main cause of voice disorders is the scarring of the vocal folds resulting from trauma, surgical manipulation, inflammatory process. Treatment of cicatricial lesions of the vocal folds remains a challenge, as far as existing methods do not ensure the recovery of the ultrastructure of the vocal folds. The authors present modern data on the structure of the vocal folds at the cellular level. Considered pathologic processes occur in different stages of scarring. Applied technologies of phonosurgery and conservative treatment, their effectiveness and shortcomings are covered. Analysis of experimental research conducted in the world demonstrates the promise of using the methods of tissue engineering to treat scarring of the vocal folds and to restore the microstructure of the latter. Identified current issues remain unresolved, which leads to the need for further experimental and clinical studies in the treatment of this pathology.

[Ab] Resumo:The aim of the study is to investigate the association between olfactory dysfunction (OD), hearing loss, and dysphonia.The cross-sectional data for 17,984 adults who completed the Korea National Health and Nutrition Examination Surveys (2010-12) were analyzed. OD, hearing loss, and dysphonia were assessed using self-reporting questionnaires. The association of OD with hearing loss and dysphonia was evaluated.Hearing loss and dysphonia were significantly more prevalent in patients with OD than in those without OD (hearing loss, 28.1% vs 11.3%; dysphonia, 11.1% vs 5.9%; both P < .0001). After adjusting for confounders, including mental stress and metabolic syndrome, the risk of OD was significantly associated with hearing loss and dysphonia, and was greater in those with combined hearing loss and dysphonia than in both patients without these dysfunctions and in those with a single dysfunction (odds ratio 3.115, 95% confidence interval 1.973-4.917).OD was significantly associated with hearing loss and dysphonia.

[Ab] Resumo:OBJECTIVES: To describe a case of vocal fold bamboo nodes leading to the diagnosis of antisynthetase syndrome, a rare autoimmune disorder. To highlight the link between these laryngeal lesions and autoimmunity. METHODS: A case of vocal fold bamboo nodes in a patient with long-standing interstitial lung disease is presented. The presence of these characteristic lesions prompted a rheumatologic workup that led to the diagnosis of a rare autoimmune disorder. RESULTS: The patient was ultimately diagnosed with antisynthetase syndrome, a rare condition characterized by inflammatory myositis and interstitial lung disease. She was treated with steroids and immunosuppressive agents with improvement in her symptoms and clinical findings. CONCLUSIONS: Vocal fold bamboo nodes are pathognomonic signs of autoimmunity. Management consists primarily of medical treatment of the underlying systemic disorder. Intralesional steroid injection or phonomicrosurgical excision may be considered for refractory cases.

[Ab] Resumo:OBJECTIVES: Clinical indications for vocal fold injection augmentation (VFI) are expanding. Prior studies demonstrate the benefit of trial VFI for select causes of glottic insufficiency. No studies have examined trial VFI for glottic insufficiency resulting from true vocal fold (TVF) scar. METHODS: Retrospective chart review of patients who underwent trial VFI for a dominant pathology of TVF scar causing dysphonia. Patients who subsequently underwent durable augmentation were identified. The primary study outcome was the difference in Voice Handicap Index-10 (VHI-10) score from pretrial VFI to post-durable augmentation. RESULTS: Twenty-eight patients underwent trial VFI for TVF scar, 22 of whom reported a positive response. Fifteen of 22 subjects who underwent durable augmentation had viable data for analysis. Mean VHI-10 improved from 26.9 to 18.6 ( P < .05), for a delta VHI-10 of 8.3, or 30.9% improvement. Twelve of the 15 (80%) showed a clinically significant improvement (delta VHI-10 >5). CONCLUSIONS: A trial VFI is a potentially useful, low-risk procedure that appears to help the patient and clinician identify when global augmentation might improve the voice when vocal fold scar is present. Patients who reported successful trial VFI often demonstrated significant improvement in their VHI-10 after subsequent durable augmentation.

[Ab] Resumo:OBJECTIVES: The aim of this study was to examine the potential of cepstral peak prominence (CPP) for predicting the intelligibility deficit in dysphonic speech. METHODS: Sentences from Hearing-in-Noise Test were recorded from 18 speakers with dysphonia and 18 speakers with normal voice. These samples were presented to 60 adults with normal hearing in quiet and noise at signal to noise ratio of +0 dB. Intelligibility was measured by orthographic transcription. Cepstral peak prominence was measured for all samples. Correlation between CPP and intelligibility score was examined. RESULTS: Intelligibility was significantly lower in dysphonic speech than normal speech in the presence of background noise. The correlation between CPP and intelligibility score was moderate when the intelligibility scores were averaged per speaker. CONCLUSIONS: Cepstral peak prominence only moderately predicts intelligibility deficit in dysphonic speech. Accordingly, CPP alone is not sufficient for describing the deficit.

[Ab] Resumo:OBJECTIVE: voice disorders are common in the pediatric population and can negatively affect children's quality of life. The pediatric voice handicap Index (pVHI) is a valid instrument to assess parental perception of their children voice but it is not translated into French language. The aim of the present study was to adapt a French version of the pVHI and to evaluate its psychometric properties including construct validity, reliability, and some aspects of external validity. PATIENTS AND METHOD: we performed a cross sectional study including 32 dysphonic children and 60 children with no history of voice problems between 3 and 12 years of age. The original pVHI was translated into French language according to forward-backward rules and then administered to parents or caregivers. Construct validity and internal consistency were explored using confirmatory factor analysis and Cronbach's alpha. The questionnaire was filled twice to assess test-retest reliability using the intra-class correlation coefficient. The external validity was explored by comparing the French pVHI total and subscales scores between dysphonic and asymptomatic children. Correlations between the French pVHI and both the perceptual GRBAS scale and the health-related quality of life (HRQOL) survey "Vécu et Santé Perçu de l'Adolescent et de l'Enfant" (VSP-Ap) were also performed. RESULTS: the structure of the French pVHI showed a good fit with excellent reliability (α = 0.929) and high test-retest reliability. Significant differences were found between the group of dysphonic children and the control group (p < 0.001). The French pVHI scores were positively correlated to all parameters of the GRBAS scale (p < 0.05). Significant negative correlations were found between the Functional domain of the pVHI and various domains of the VSP-Ap as Leisure Activities, Schooling and Sentimental Relationship (p < 0.05). CONCLUSION: the French pVHI is considered to be a valid and reliable instrument to assess voice-related quality of life in children with voice disorder. We recommend its use in the multidimensional protocols for assessing voice disorder in the pediatric population.

[Ab] Resumo:OBJECTIVE: To measure the risk of dysphonia in teachers, as well as investigate whether the perceptual-auditory and acoustic aspects of the voice of teachers in situations of silence and noise, the signal-to-noise ratio, and the noise levels in the classroom are associated with the presence of dysphonia. METHODS: This is an observational cross-sectional research with 23 primary and secondary school teachers from a private school in the municipality of São Paulo, Brazil, divided into the groups without dysphonia and with dysphonia. We performed the following procedures: general Dysphonia Risk Screening Protocol (General-DRSP) and complementary to speaking voice - teacher (Specific-DRSP), voice recording during class and in an individual situation in a silent room, and measurement of the signal-to-noise ratio and noise levels of classrooms. RESULTS: We have found differences between groups regarding physical activity (General-DRSP) and particularities of the profession (Specific-DRSP), as well as in all aspects of the perceptual-auditory vocal analysis. We have found signs of voice wear in the group without dysphonia. Regarding the vocal resources in the situations of noise and silence, we have identified a difference for the production of abrupt vocal attack and the tendency of a more precise speech in the situation of noise. Both the signal-to-noise ratio and the room noise levels during class were high in both groups. CONCLUSIONS: Teachers in both groups are at high risk for developing dysphonia and have negative vocal signals to a greater or lesser extent. Signal-to-noise ratio was inadequate in most classrooms, considering the standards for both children with normal hearing and with hearing loss, as well as equivalent noise levels.

[Ab] Resumo:OBJECTIVE: To examine the distribution of clinic and operative pathology in a tertiary care laryngology practice. METHODS: Probability density and cumulative distribution analyses (Pareto analysis) was used to rank order laryngeal conditions seen in an outpatient tertiary care laryngology practice and those requiring surgical intervention during a 3-year period. RESULTS: Among 3783 new clinic consultations and 1380 operative procedures, voice disorders were the most common primary diagnostic category seen in clinic (n = 3223), followed by airway (n = 374) and swallowing (n = 186) disorders. Within the voice strata, the most common primary ICD-9 code used was dysphonia (41%), followed by unilateral vocal fold paralysis (UVFP) (9%) and cough (7%). Among new voice patients, 45% were found to have a structural abnormality. The most common surgical indications were laryngotracheal stenosis (37%), followed by recurrent respiratory papillomatosis (18%) and UVFP (17%). CONCLUSIONS: Nearly 55% of patients presenting to a tertiary referral laryngology practice did not have an identifiable structural abnormality in the larynx on direct or indirect examination. The distribution of ICD-9 codes requiring surgical intervention was disparate from that seen in clinic. Application of the Pareto principle may improve resource allocation in laryngology, but these initial results require confirmation across multiple institutions.

[Ab] Resumo:Objective The purpose of this review is to describe the recent advances in identifying possible factors involved in the pathogenesis of spasmodic dysphonia. Spasmodic dysphonia is a task-specific focal laryngeal dystonia characterized by irregular and uncontrolled voice breaks. Pathogenesis of the disorder is poorly understood. Data Sources PubMed, Google Scholar, and Cochrane Library. Review Methods The data sources were searched using the following search terms: ( spasmodic dysphonia or laryngeal dystonia) and ( etiology, aetiology, diagnosis, pathogenesis, or pathophysiology). Conclusions Several potential etiological factors have been proposed by epidemiological, genetic, and neuropathological studies. Spasmodic dysphonia is a rare disorder primarily affecting females beginning in their 40s. Vocal tremor co-occurs in 30% to 60%. Large cohort studies identified risk factors such as a family history of neurological disorders including dystonia and tremor, recent viral illness, and heavy voice use. As none are rare events, a complex interactive process may contribute to pathogenesis in a small proportion of those at risk. Consequences to pathogenesis are neurological processes found in spasmodic dysphonia: loss of cortical inhibition, sensory processing disturbances, and neuroanatomical and physiological differences in the laryngeal motor control system. Implications for Practice Diagnosis of spasmodic dysphonia usually includes speech and laryngoscopic assessment. However, as diagnosis is sometimes problematic, measurement of neurophysiological abnormalities may contribute useful adjuncts for the diagnosis of spasmodic dysphonia in the future.
