Abstract Introduction: Reinke’s Edema (RE) is a laryngeal lesion related to excessive tobacco smoking, voice overuse, and laryngopharyngeal reflux. Although the risk of malignancy has been considered low in literature, RE is classified among precancerous lesions. Objectives: We investigated DNA Copy Number Alterations (CNAs) in specimens of RE and its potential association with malignant progression. Methods: We used array-based comparative genomic hybridization (aCGH, Agilent 4 × 180 K platform) to study eight RE cases. All patients were heavy tobacco users for at least 30 years, and none of them progressed to cancer in the follow-up (>8 years). Two RE presented mild dysplasia, one moderate dysplasia, and no histological alterations were found in the remaining five cases. CNAs were compared with the Database of Genomic Variants (DGV) and genes mapped on altered regions had their functions annotated. Results: Six of eight patients showed different rare copy number alterations on chromosomes 2q37.3, 4q13.1, 4q13.3, 7q11.22, 10p14, and 13q34. A gain of the whole chromosome 8 were detected in one case. Of interest, four of eight RE cases showed copy number imbalances involving genes previously described in several tumor types (RASA3, COL6A3, LINC00707, LINP1, SMR3A, and SMR3B). Conclusion: The genomic imbalances herein found in RE have the potential to contribute to the phenotype but with limited or no risk of cancer. A long-term follow-up in a large series of patients could clarify the mechanisms involved in the malignant progression of RE. Level of evidence: 4.

Abstract Introduction Laryngeal leukoplakia corresponds to a white lesion in the mucosa developed by the deposit of keratin in the epithelium, potentiated by chronic smoking. It is considered a preneoplastic lesion. Surgery is the most adopted treatment; however, non-surgical treatment is advocated by some authors. Objective To evaluate the effectiveness of vitamin A in the management of vocal fold leukoplakia. Methods Patients with videolaryngoscopy diagnosis of vocal fold leukoplakia were selected. The endoscopic images were photographed and with the aid of the ImageJ software (National Institutes of Health, Bethesda, MD, USA), the proportion of the size of the leukoplakia was calculated. Eligible patients were prescribed 50,000U of vitamin A, twice daily for 2 months, at which point videolaryngostroboscopy was repeated for comparative analysis between pre and posttreatment. The efficacy of the treatment was classified as: outcome I – complete improvement of the lesion, outcome II – partial improvement, and outcome III – no difference or increased lesion size. Results Fifteen patients (eight women, seven men) were included, six of whom had bilateral lesions. Smoking was reported in 86.8% of patients. Complete improvement of the lesion was found in 7 cases (33.4%, outcome I), partial improvement in 6 (28.6%, outcome II), and worsening of the injury in 8 (38.1%, outcome III). Of the latter, 6 underwent microsurgery; histopathology indicated absence of dysplasia in 3, and mild dysplasia in 3. Conclusions In this study, the treatment with vitamin A at a dose of 100,000 IU daily for 2 months was effective in reducing the laryngeal leukoplakia size in 62% of cases. epithelium smoking however nonsurgical non surgical authors selected National Health Bethesda MD USA, USA , USA) calculated 50000U U 50 000U posttreatment as eight women men included lesions 868 86 86.8 33.4%, 334 33 4 (33.4% I, I) 28.6%, 286 28 (28.6% II, II) 38.1%, 381 38 1 (38.1% III. .

Abstract Introduction Dysphonia and lower pitch after surgery of Reinke edema are common. They are caused especially due to chronic smoking but, probably, other factors should be associated. Objectives To evaluate the results of laryngeal microsurgery in patients with Reinke edema, following a standardized postoperative guidance protocol in our service. Methods Retrospective study. Thirty patients (3 males; 27 females) were included, 70% between 41 and 60 years old. The parameters analyzed in the pre- and postoperative (between 4 and 6 months) of patients undergoing laryngeal microsurgery for Reinke edema were: smoking, vocal symptoms, videolaryngostroboscopy, voice therapy, perceptual and acoustic vocal evaluation, histopathological report. Results Smoking was reported by 100% of the patients and maintained in the postoperative period by 80%. Complete improvement of symptoms in the postoperative period was reported by 43% of them, partial improvement by 40%, and maintenance by 17%. There was low adherence to voice therapy in the pre- and postsurgery. Postoperative videolaryngoscopy indicated congestion (19), atrophy and bowed vocal fold (1), subepithelial edema (2), and normal findings (8). The histological findings were subepithelial edema, enlargement of vessels, inflammation, epithelial hyperplasia, and thickening of the basement membrane. The perceptual and acoustic vocal analyzes indicated improvement of the analyzed parameters. Conclusions The maintenance of some vocal symptoms and laryngeal alterations in videolaryngoscopy after microsurgery of Reinke edema is frequent, even in patients who follow the recommendations of vocal rest and control of gastroesophageal reflux. Vocal symptoms are attributed to changes in the laryngeal mucosa caused by chronic smoking, aggravated by the maintenance of addiction in the postoperative period. common but probably associated service study 3 ( males 2 females included 70 old pre months videolaryngostroboscopy evaluation report 100 80 80% 43 them 40 40% 17 17% postsurgery 19, 19 , (19) 1, 1 (1) 2, (2) 8. 8 .

RESUMO Objetivo Avaliar os achados audiológicos de recém-nascidos expostos à sífilis materna, tratada adequadamente na gestação. Métodos Estudo de coorte única não concorrente, realizado em um hospital público. Fizeram parte da amostra recém-nascidos filhos de mães que apresentaram sorologia positiva para sífilis e que realizaram o tratamento adequado durante a gestação, compondo o grupo estudo, e recém-nascidos sem indicadores de risco para deficiência auditiva, grupo comparação. Resultados Participaram do estudo 90 recém-nascidos, sendo 41 do grupo estudo e 49 do grupo comparação. No exame de emissões otoacústicas por estímulo transiente, todos apresentaram presença de resposta bilateralmente e, na comparação das amplitudes de respostas nas bandas de frequências de 3,0 kHz, 3,5 kHz e 4,0 kHz observou-se menor amplitude de resposta no grupo exposto, com diferença estatisticamente significativa para a frequência de 4 kHz à direita. Na análise das respostas do exame de potencial evocado auditivo de tronco encefálico, não se observou assimetria de resposta entre as orelhas que sugerisse alteração retrococlear e nem diferenças nos valores das latências absolutas ou intervalos interpicos, entre os grupos. Conclusão As respostas eletroacústicas foram discretamente inferiores nos recém-nascidos exposto à sífilis materna, enquanto que as respostas eletrofisiológicas foram semelhantes às encontradas na população de baixo risco para deficiência auditiva.

ABSTRACT Purpose To evaluate the audiological findings of newborns exposed to maternal syphilis, properly treated during pregnancy. Methods This was a single, non-concurrent cohort study conducted in a public hospital. The sample included newborns whose mothers had positive syphilis serology and who underwent adequate treatment during pregnancy, composing the study group, and newborns without risk indicators for hearing loss, as a comparison group. Results Ninety newborns participated in the study, 41 were the study group and 49 were the comparison group. In the transient evoked otoacoustic emissions test, all newborns showed a bilateral response, and when comparing the amplitudes of responses in the 3.0 kHz, 3.5 kHz and 4.0 kHz frequency bands, a smaller amplitude of response in the studied group with a statistically significant difference for the frequency of 4 kHz on the right was observed. An analysis of the response of the brainstem auditory evoked potential test showed no asymmetry of response between the ears that suggest a retrocochlear alteration, nor difference in the values of absolute latencies or interpeak intervals between groups. Conclusion The electroacoustic responses were slightly lower in newborns exposed to maternal syphilis, whereas their electrophysiological responses were similar to those found in the population at low risk for hearing loss.

SUMMARY BACKGROUND: Recurrent laryngeal papillomatosis, caused by the Human Papilloma Virus, has a significant economic impact worldwide and there are no epidemiological data of this disease in Brasil. OBJECTIVE: The objective of the study was to estimate the incidence and prevalence of laryngeal papillomatosis of some otorhinolaryngology centers in São Paulo State (Brasil). METHODS: A questionnaire containing data on the number of new and follow-up cases diagnosed with laryngeal papillomatosis was sent to the Otorhinolaryngology services (n=35) of São Paulo State (Brasil). RESULTS: A total of 20 otorhinolaryngology centers answered the questionnaire. Of these, the five largest regional health centers were selected as follows: Campinas (42 cities – 4,536,657 inhabitants), Sao Jose do Rio Preto (102 cities – 1,602,845 inhabitants), Ribeirão Preto (26 cities – 1,483,715 inhabitants), Bauru (68 cities – 1,770,427 inhabitants), and Sorocaba (47 cities – 2,478,208 inhabitants). The incidence and prevalence of each regional health centers were, respectively: Campinas (5.51;7.27), Sorocaba (2.02;6.86), São José do Rio Preto (1.87;7.49), Ribeirão Preto (11.46;22.92), and Bauru (3.95;7.91). CONCLUSION: The incidence and prevalence of the laryngeal papillomatosis of the five largest regional health centers of the interior of São Paulo State (Brasil) varied between 1.87 to 11.46 and 6.86 to 22.92 per 1,000,000 inhabitants, respectively for a total population of 11,871,852 inhabitants.

Abstract Introduction Laryngeal granulomas are benign, recurrent lesions of many causes (reflux, voice abuse, intubation, and idiopathic), which renders its treatment difficult. Objective To describe our experience in the treatment of laryngeal granulomas. Methods From 16 medical records of the patients with laryngeal granulomas seen between 2010 and 2017 in a university hospital, the following data were analyzed: age, gender, vocal and gastroesophageal symptoms, vocal overuse, intubation, treatments, videolaryngoscopy before and after the treatment. Results Gender: female, 10; male, 6. Age: between 20 and 60 years old (11%). Etiology of the granulomas: intubation (9), reflux (4), idiopathic (3). The initial treatments adopted in all cases were: inhaled beclomethasone dipropionate 100 μg 12/12 hours (1month), proton pump inhibitor, omeprazole 40 mg/day (2months), and dietary and voice education. After this period, 10 patients (7 postintubation, 3 idiopathic) were submitted to surgery, since no improvements in the symptoms or in the lesions were seen. Of these, two recurred, requiring a second surgery, one of which recurred six times and received botulinum toxin A. Only one patient with granulomas due to laryngopharyngeal reflux presented no improvement in the symptoms nor in the lesion after the pharmacological treatment and had been submitted to microsurgery. All of the other patients with reflux granulomas were successfully treated with the drug treatment, and the longest treatment time for complete remission of the symptoms and of the lesions was 9 months. Conclusions In laryngeal granulomas caused by reflux, treatment with inhaled steroids and proton pump inhibitors proved to be effective, although prolonged. In postintubation and idiopathic granulomas, surgery was the best treatment.

Objetivo: Analisar os sintomas vocais, auditivo-perceptivos e acústica vocal, videolaringoscopia, procedimento cirúrgico e achados histopatológicos em pacientes submetidos à tireoidectomia. Método: Estudo prospectivo. Pacientes submetidos à tireoidectomia foram avaliados da seguinte forma: anamnese, laringoscopia e avaliações vocais acústicas. Momentos: pré-operatório, 1ª avaliação pós (15 dias), 2ª avaliação pós (1 mês), 3ª avaliação pós (3 meses) e 4ª avaliação pós-operatória (6 meses). Resultados: Dos 151 pacientes, 130 eram mulheres e 21, homens. Tipos de cirurgia: lobectomia + istmectomia n = 40, tireoidectomia total n = 88, tireoidectomia + dissecção de linfonodo n = 23. Sintomas vocais foram relatados por 42 pacientes na 1ª avaliação pós-operatória (27,8%), reduzidos para 7,2% após 6 meses. Na análise acústica, f0 e APQ estavam diminuídos nas mulheres. As videolaringoscopias mostraram que 144 pacientes (95,3%) tiveram exames normais no momento pré-operatório. Paralisia das cordas vocais foi diagnosticada em 34 pacientes na 1ª avaliação pós-operatória, 32 do nervo laríngeo recorrente (lobectomia + istmectomia - n = 6; tireoidectomia total - n = 17; tireoidectomia total + dissecção de linfonodos - n = 9) e 2 do nervo laríngeo superior (lobectomia + istmectomia - n = 1; tireoidectomia total + dissecção de linfonodos - n = 1). Após 6 meses, 10 pacientes persistiram com paralisia do nervo laríngeo recorrente (6,6%). Histopatologia e correlação com paralisia das cordas vocais: bócio coloide nodular (n = 76; paralisia n = 13), tireoidite (n = 8; paralisia n = 0) e carcinoma (n = 67; paralisia n = 21). Conclusão: Os sintomas vocais, relatados por 27,8% dos pacientes na 1ª avaliação pós-operatória, diminuíram para 7% em 6 meses. Na análise acústica, f0 e APQ diminuíram. A paralisia transitória de cordas vocais secundária à lesão do nervo laríngeo recorrente e nervo laríngeo superior ocorreu, respectivamente, em 21% e 1,3% dos pacientes, reduziu-se para 6,6% e 0% após 6 meses.

Abstract Introduction: Dysphonia is a common symptom after thyroidectomy. Objective: To analyze the vocal symptoms, auditory-perceptual and acoustic vocal, videolaryngoscopy, the surgical procedures and histopathological findings in patients undergoing thyroidectomy. Methods: Prospective study. Patients submitted to thyroidectomy were evaluated as follows: anamnesis, laryngoscopy, and acoustic vocal assessments. Moments: pre-operative, 1st post (15 days), 2nd post (1 month), 3rd post (3 months), and 4th post (6 months). Results: Among the 151 patients (130 women; 21 men). Type of surgery: lobectomy + isthmectomy n = 40, total thyroidectomy n = 88, thyroidectomy + lymph node dissection n = 23. Vocal symptoms were reported by 42 patients in the 1st post (27.8%) decreasing to 7.2% after 6 months. In the acoustic analysis, f0 and APQ were decreased in women. Videolaryngoscopies showed that 144 patients (95.3%) had normal exams in the preoperative moment. Vocal fold palsies were diagnosed in 34 paralyzes at the 1st post, 32 recurrent laryngeal nerve (lobectomy + isthmectomy n = 6; total thyroidectomy n = 17; thyroidectomy + lymph node dissection n = 9) and 2 superior laryngeal nerve (lobectomy + isthmectomy n = 1; Total thyroidectomy + lymph node dissection n = 1). After 6 months, 10 patients persisted with paralysis of the recurrent laryngeal nerve (6.6%). Histopathology and correlation with vocal fold palsy: colloid nodular goiter (n = 76; palsy n = 13), thyroiditis (n = 8; palsy n = 0), and carcinoma (n = 67; palsy n = 21). Conclusion: Vocal symptoms, reported by 27.8% of the patients on the 1st post decreased to 7% in 6 months. In the acoustic analysis, f0 and APQ were decreased. Transient paralysis of the vocal folds secondary to recurrent and superior laryngeal nerve injury occurred in, respectively, 21% and 1.3% of the patients, decreasing to 6.6% and 0% after 6 months.

Resumo: Introdução: Granulomas laríngeos pós-intubação são lesões laríngeas benignas, porém recorrentes. Não há um consenso na literatura em relação ao seu tratamento. Objetivo: Descrever a eficácia de diferentes modalidades de tratamento para granulomas laríngeos primários ou recorrentes resultantes da intubação endotraqueal. Método: Estudo-revisão sistemática e metanálise proporcional. Critérios de elegibilidade: estudos experimentais ou observacionais com pelo menos cinco indivíduos. Desfechos estudados: resolução do granuloma, recorrência e tempo de resolução. Bases de dados usadas: Pubmed, Embase, Lilacs e Cochrane. Foi usado o software Stats Direct 3.0.121. Resultados: Foram selecionados seis estudos, com 85 pacientes. Os tratamentos registrados foram: terapia antirrefluxo, terapia da voz, medicamentos anti-inflamatórios, esteroides, antibióticos, sulfato de zinco e cirurgia. Receberam tratamento primário 85 pacientes de seis estudos: cirurgia ± associações (41 pacientes), chance de resolução de 75% (IC 95% 0,3% a 100%, I2 = 90%) e risco absoluto de recorrência de 25% (IC 95%: 0,2% a 71%); tratamento clínico (44 pacientes), chance de resolução de 86% (IC 95%: 67% a 97%) e risco absoluto de recorrência de 14% (IC 95%: 3% a 33%). Não houve diferença significante entre os grupos. Três estudos, que abrangeram 19 pacientes, analisaram o tratamento secundário (falha ou recorrência após o tratamento primário); três indivíduos apresentaram nova recorrência. O tempo necessário para resolver as lesões variou de imediato, logo após a cirurgia, até 23 meses, com tratamento com esteroides inalados. Conclusão: Não há evidências de alta qualidade que provem a eficácia de qualquer tratamento para granulomas laríngeos resultantes da intubação endotraqueal.

Abstract Introduction: Laryngeal granulomas post intubation are benign but recurrent lesions. There is no consensus for its treatment. Objective: To describe the effectiveness of different treatment modalities for primary or recurrent laryngeal granulomas resulting from endotracheal intubation. Methods: Systematic review and proportional meta-analysis. Eligibility criteria - experimental or observational studies with at least five subjects. Outcomes studied - granuloma resolution, recurrence, and time for resolution. Databases used - Pubmed, Embase, Lilacs, and Cochrane. The Stats Direct 3.0.121 program was used. Results: Six studies were selected, with 85 patients. The treatments registered were: antireflux therapy, speech therapy, anti-inflammatory drugs, steroids, antibiotics, zinc sulfate and surgery. 85 patients from six studies had primary treatment: surgery ± associations (41 patients), resolution chance 75% (95% CI: 0.3-100%, I 2 = 90%), absolute relapse risk 25% (95% CI: 0.2-71%); medical treatment (44 patients), resolution chance 86% (95% CI: 67-97%); and absolute relapse risk 14% (95% CI: 3-33%). There was no significant difference between groups. Three studies, encompassing 19 patients, analyzed secondary treatment (failure or recurrence after primary treatment); three subjects presented new recurrence. The time needed to resolve the lesions varied from immediate, after surgery, to 23 months, for inhaled steroid. Conclusion: There is no evidence of high quality that proves the efficacy of any treatment for laryngeal granulomas resulting from endotracheal intubation.

Introduction: Psychogenic dysphonia is a functional disorder with variable clinical manifestations. Objective: To assess the clinical and vocal characteristics of patients with psychogenic dysphonia in a case series. Methods: The study included 28 adult patients with psychogenic dysphonia, evaluated at a University hospital in the last ten years. Assessed variables included gender, age, occupation, vocal symptoms, vocal characteristics, and videolaryngostroboscopic findings. Results: 28 patients (26 women and 2 men) were assessed. Their occupations included: housekeeper (n = 17), teacher (n = 4), salesclerk (n = 4), nurse (n = 1), retired (n = 1), and psychologist (n = 1). Sudden symptom onset was reported by 16 patients and progressive symptom onset was reported by 12; intermittent evolution was reported by 15; symptom duration longer than three months was reported by 21 patients. Videolaryngostroboscopy showed only functional disorders; no patient had structural lesions or changes in vocal fold mobility. Conversion aphonia, skeletal muscle tension, and intermittent voicing were the most frequent vocal emission manifestation forms. Conclusions: In this case series of patients with psychogenic dysphonia, the most frequent form of clinical presentation was conversion aphonia, followed by musculoskeletal tension and intermittent voicing. The clinical and vocal aspects of 28 patients with psychogenic dysphonia, as well as the particularities of each case, are discussed.

OBJETIVO: avaliar se a Lei Seca cumpriu sua meta após três anos da promulgação. MÉTODOS: estudo retrospectivo dos pacientes com fraturas craniofaciais submetidos a tratamento cirúrgico em um hospital universitário, em dois períodos: antes (2005 a 2008) e após a implantação da lei (2008 a 2011). RESULTADOS:foram operados 265 pacientes (220 homens e 45 mulheres) nesse período sendo, 149 (56%) antes da lei e 116 (44%) após a lei, indicando redução no número de traumatismos (p=0,04). Houve predomínio da faixa etária entre 19 e 40 anos, em ambos os períodos. As principais causas dos traumas foram os acidentes automobilísticos, as agressões físicas e as quedas. O abuso de álcool foi identificado em 15,4% dos pacientes antes e 19% após a lei. A mandíbula e o complexo maxilozigomático foram os ossos mais acometidos. CONCLUSÃO:a redução no número de politraumatizados operados ficou aquém do esperado e almejado.

OBJECTIVE: To assess whether the Brazilian Driving Dry Law reached its goal after the three years following its enactment. METHODS: We onnducted a retrospective study of patients with craniofacial fractures who underwent surgery at a university hospital in two periods: before the Law (2005 to 2008) and after the Law (2008 to 2011). RESULTS: 265 patients (220 men and 45 women) were operated on during this period, 149 (56%) before and 116 (44%) after the Law, which indicates a reduction in the number of traumatisms (p=0.04). The age range between 19 and 40 years predominated in both periods. The main causes of traumas were car accidents, physical aggression and falls. Alcohol abuse was identified in 15.4% patients before and 19% patients after the enactment. The jaw and the maxillo-zygomatic complex were the most affected bones. CONCLUSION: The drop in the number of polytraumatized patients operated on at this institution in the three years following the Driving Dry Law was 22%, which is below the expected and desired percentage. These results must be compared to those of different services offering the same attendance type in order to compile data and enlarge statistics. The low index of reduction in the number of traumatisms and the report of alcohol abuse by several patients at the moment of trauma, even after the law, evidence the need of adopting stricter measures to control and punish violators.

OBJETIVO: Investigar as alterações laríngeas e vocais em pacientes com sintomas de refluxo gastroesofágico e correlacioná-las com o exame de phmetria. MÉTODOS: Estudo prospectivo que incluiu os pacientes atendidos nos ambulatórios de Distúrbios da Voz da Faculdade de Medicina de Botucatu no período de cinco anos com sintomas vocais e gastroesofágicos. Os pacientes foram submetidos à videolaringoscopia, às análises vocais perceptivo-auditivas, a analise vocal acústica computadorizada e ao exame de pHmetria de dois canais com monitorização durante 24 horas. RESULTADOS: Foram incluídos 57 pacientes (entre 21 a 65 anos; 45 mulheres e 12 homens). Desses, 18 apresentavam pHmetria normal (31,6%) e 39 alterada (68,4%). As videolaringoscopias registraram diversas lesões laríngeas tanto nos pacientes com pHmetria normal como alterada, sendo mais relevantes neste último grupo, destacando-se a paquidermia posterior. As avaliações vocais perceptivo-auditivas identificaram alterações vocais de diversas intensidades em ambos os grupos, mais importantes nos pacientes com pHmetria alterada. Todos os parâmetros acústicos, exceto Fo, mostraram-se alterados em ambos os grupos, quando comparados aos controles. CONCLUSÕES: Alterações vocais perceptivas e acústicas, e lesões laríngeas foram registradas tanto nos pacientes com phmetria normal como alterada, sinalizando para a importância da historia clínica e dos achados videolaringoscópicos no diagnóstico das laringites ácidas.

PURPOSE: To investigate laryngeal and voice disorders in patients with gastroesophageal symptoms and their correlation with pH-monitoring. METHODS: A prospective study was carried out in patients attended at the Voice Disorder Outpatient Clinics of Botucatu Medical School in a five-year period and had vocal and gastroesophagic symptoms. Patients underwent videolaryngoscopy, auditory-perceptual vocal analyses, computerized acoustic vocal analysis and dual probe pH-monitoring for 24 hours. RESULTS: Fifty-seven patients were included (aged between 21 and 65 years; 45 women and 12 men), 18 had normal (31.6%) and 39 had abnormal pH-monitoring results (68.4%). Videolaryngoscopy recorded several laryngeal lesions for both patients with normal and abnormal pH-monitoring, but mostly for the latter group, highlighting posterior pachyderma. Auditory-perceptual vocal assessments identified vocal changes of several intensities for both groups but especially for patients with abnormal pH-monitoring results. All acoustic parameters, except f0, were abnormal for both groups, compared to the control population. CONCLUSION: Acoustic and perceptual vocal changes and laryngeal lesions were recorded for both patients with normal pH-monitoring results and patients with abnormal pH-monitoring results, evidencing the importance of clinical history and videolaryngoscopic findings for diagnosing acid laryngitis.

OBJETIVOS: Determinar a prevalência de disfonia em crianças, baseando-se nos julgamentos dos pais, nas ava-liações vocais perceptivas e acústicas, analisar sintomas associados, fatores de risco e achados vide-olaringoscópicos. CASUÍSTICA E MÉTODOS: Os pais de 2.000 crianças responderam questionário sobre qualidade vocal do filho. As crianças foram submetidas às avaliações vocais perceptiva, acústicas e videolaringoscopias. RESULTADOS: Participaram 1.007 meninos e 993 meninas. Sintomas esporádicos foram reportados por 206 pais e permanentes, por 123. Na avaliação perceptiva, o parâmetro G (Grau de disfonia) recebeu escore 0 em 694 vozes, 1 em 1065 e 2 em 228. Houve diminuição de f0 com a idade e os demais parâmetros acústicos mostraram-se mais elevados nas crianças com escore de G em 2. Nas videolaringoscopias, destacaram-se nódulos, espessamentos e inflamação. CONCLUSÕES: O julgamento dos pais indicou prevalência de disfonia em 6,15%, e as análises perceptivas em 11,4%. Os sintomas vocais relacionaram-se à sobrecarga fonatória. Quadros nasossinusais, abuso vocal e ruído foram importantes fatores de risco. As análises acústicas mantiveram relação direta com as perceptivo-auditivas. Lesões laríngeas foram detectadas nas videolaringoscopias, destacando nódulos, espessamentos e inflamação.

Children dysphonia studies have reported an incidence of 4.4 to 30.3%. GOALS: To establish the prevalence of dysphonia in children, based on the opinion of the parents, acoustic and vocal-perceptual assessments, associated symptoms, risk factors and videolaryngoscopy findings. MATERIALS AND METHODS: The parents from 2,000 children answered a questionnaire about the vocal quality of their children, and these children were submitted to perceptual vocal, acoustic and videolaryngoscopy assessments. RESULTS: We had 1,007 boys and 993 girls; sporadic symptoms were reported by 206 parents and permanent symptoms were reported by 123. In the perceptual assessment, the G parameter (degree of dysphonia) had a score of 0 in 694 voices; 1 in 1,065 and 2 in 228. There was f0 reduction with age and the remaining acoustic parameters were high in children with a G score of 2. Nodules, thickening and inflammation were the most common in the videolaryngoscopy exams. CONCLUSIONS: Parental judgment indicated a prevalence of dysphonia in 6.15%, and perceptual analysis yielded a value of 11.4%. Vocal symptoms were associated with a phonatory overload. sinonasal disorders, vocal abuse and noise were considered relevant risk factors. The acoustic analysis kept a direct association with the perceptual-auditory. Laryngeal lesions were found in the videolaryngoscopy exams, stressing nodules, thickening and inflammation.

OBJETIVO: Avaliar as alterações morfológicas no epitélio traqueal de cães expostos à inalação de gases pouco condicionados, sob ventilação com tubo traqueal (TT) ou máscara laríngea (ML). MÉTODOS: Doze cães adultos foram divididos aleatoriamente em dois grupos: grupo TT (n-6) e grupo ML (n-6), submetidos à anestesia venosa e ventilação mecânica, em sistema sem reabsorção de CO2. Foram registrados parâmetros hemodinâmicos e ventilatórios, temperatura timpânica, temperatura, umidade relativa e absoluta do ar ambiente e dos gases inalados durante 3 horas. Ao término do experimento, os animais foram submetidos a eutanásia e realizadas biópsias ao longo do segmento traqueal para estudo morfológico. Três cães saudáveis foram utilizados para controle morfológico. RESULTADOS: A temperatura dos gases inalados manteve-se entre 24ºC e 26ºC, a umidade relativa entre 10% e 12%, e umidade absoluta entre 2 -3 mg H2O.L-1 sem diferença significativa entre os grupos. Em ambos os grupos a análise histológica evidenciou processo inflamatório epitelial e congestão no córion, e a microscopia eletrônica de varredura mostrou agrupamento e desorganização ciliar. A microscopia eletrônica de transmissão detectou maiores alterações no grupo TT do que no ML, como alargamento das junções intercelulares, desorientação ciliar, vacuolização citoplasmática, alterações nucleares como pcinose e condensação da cromatina. CONCLUSÃO: A máscara laríngea determinou alterações menos pronunciadas no epitélio traqueal de cães expostos à inalação de gases pouco condicionados.

PURPOSE: To study morphological findings in the tracheal epithelium of dogs exposed to the inhalation of poorly conditioned gases under use of an endotracheal tube (ET) or laryngeal mask airway (LMA). METHODS: Twelve dogs randomly were allocated to two groups: ET group (n-6) and LMA group (n-6), anaesthetized and mechanically ventilated, without CO2 reabsorption. Haemodynamic and ventilatory parameters, tympanic temperature, temperature, relative and absolute humidity of the ambient and inhaled gases were analyzed during three hours. The animals were submitted to euthanasia and biopsies were carried out along the tracheal segment to morphological study. Three healthy dogs were used to morphological control. RESULTS: Inhaled gas temperature was maintained between 24ºC and 26ºC, relative humidity between 10% and 12%, and absolute humidity between 2 - 3 mg H2O.L-1 with no significant differences between groups. In both groups, histological analysis showed epithelial inflammation and congestion in the corion and scanning electron microscopy showed ciliary grouping and disorganization. Transmission electron microscopy showed higher alterations in ET group than LMA group as widening of cell junctions, ciliary disorientation, cytoplasmic vacuolization, nuclear abnormalities, picnosis and chromatin condensation. CONCLUSION: LMA determined less pronounced changes in the tracheal epithelium in dogs exposed to the inhalation of poorly conditioned gases.
