Elaboração de um instrumento para predizer o fechamento velofaríngeo com base nas características de fala e sua correspondência com as dimensões do orifício velofaríngeo / Developing a tool for predicting velopharyngeal closure based on speech characteristics and its correspondence with the velopharyngeal orifice area

Scarmagnani, Rafaéli Higa 24 February 2017 (has links)
Introdução: Indivíduos com fissura labiopalatina podem apresentar alterações de fala específicas decorrentes da disfunção velofaríngea. Objetivo: Elaborar um intrumento para predizer o fechamento velofaríngeo (FVF), baseado na combinação dos sintomas de fala decorrentes da disfunção velofaríngea, aferidas na avaliação perceptivo-auditiva da fala e sua correspondência com a medida objetiva da dimensão do orifício velofaríngeo. Material e Método: Participaram deste estudo, 78 pacientes, com fissura de palato operada, com idade entre 6 e 45 anos. Os pacientes foram submetidos à avaliação aerodinâmica da fala por meio da técnica fluxo-pressão para classificação do FVF (medida da área velofaríngea) e à gravação audiovisual de amostra de fala. As amostras de fala foram editadas e analisadas por três fonoaudiólogas para classificação dos sintomas: hipernasalidade, emissão de ar nasal audível, classificação da competência velofaríngea, turbulência nasal, fraca pressão consonantal, sintomas ativos-articulação compensatória e mímica facial. A correlação entre as características perceptivas da fala e a classificação do FVF foi feita utilizando-se o coeficiente de correlação de Spearman. Foram desenvolvidos dois modelos estatísticos (discriminante e exploratório) a fim de predizer a classificação do FVF. Os testes de sensibilidade e especificidade foram aplicados a fim de se verificar a aplicabilidade clínica dos modelos. Resultados: Verificou-se forte correlação entre todos os sintomas de fala e a classificação do FVF. Ambos os modelos mostraram 88,7% de acertos ao predizer o FVF. A sensibilidade e especificidade para o modelo discriminante foi de 92,3% e 97,2%, respectivamente e de, 96,2% e 94,4% para o modelo exploratório, respectivamente. Conclusão: Foram desenvolvidas e apresentadas dois instrumentos para predizer o FVF a partir dos sintomas perceptivos da fala e a sua correspondência com o fechamento velofaríngeo determinado pela avaliação objetiva. Acredita-se que tais ferramentas contribuirão para o diagnóstico da disfunção velofaríngea na prática clínica. / Introduction: Individuals with cleft lip and palate may present specific speech disorders due to velopharyngeal dysfunction. Objective: To develop a tool in order to predict velopharyngeal closure (VFC), based on the combination of speech symptoms of velopharyngeal dysfunction, assessed in the auditory-perceptual evaluation and its correspondence with the instrumental measurement of velopharyngeal orifice size. Methods: Seventy eight patients with repaired cleft palate, aged 6 to 45 years, participated in this study. The patients undergone aerodynamic evaluation by means of pressure-flow technique to determine velopharyngeal closure (velopharyngeal orifice area) and audiovisual recording of speech samples. The samples were edited and analyzed by three speech-language pathologists for rating the symptoms: hypernasality, audible nasal air emission, velopharyngeal competence rating, nasal turbulence, weak pressure consonant, active symptoms (compensatory articulation error) and facial grimacing. Correlation between the perceptual speech characteristics and the velopharyngeal closure was performed by Spearman\'s correlation coefficient. Two statistical models (discriminant and exploratory) were developed to predict the VFC. The sensitivity and specificity tests were performed in order to verify the clinical applicability of the models. Results: There was a strong correlation between all speech symptoms and VFC. Both models showed 88.7% of accuracy on predicting VFC. The sensitivity and specificity for the discriminant model were 92.3% and 97.2%, respectively, and 96.2% and 94.4% for the exploratory model, respectively. Conclusion: In the present study two tools were developed and presented to predict VFC based on speech symptoms and its correspondence with the velopharyngeal closure determined by the objective evaluation. Both tools may contribute to the diagnosis of velopharyngeal dysfunction in clinical practice.

Resultados de fala do tratamento oferecido de rotina a crianças com fissura de palato isolada em unidade hospitalar especializada: avaliação da nasalidade e da nasalância aos 5 anos de idade / Speech outcomes of the routine treatment offered to children with isolated cleft palate at a specialized hospital unit: nasality and nasalance assessment at 5 years of age

Oliveira, Debora Natalia de 21 February 2017 (has links)
Objetivo: Avaliar os resultados de fala do tratamento cirúrgico da fissura de palato isolada oferecido de rotina no HRAC-USP, por meio de avaliação perceptivo-auditiva e nasométrica, em crianças de 5 anos de idade. Métodos: Estudo prospectivo conduzido em 27 crianças com fissura de palato isolada operada, de uma amostra total de 52 crianças recrutadas, em um período de 9 meses, com idade variando entre 4:8 a 5:6 anos, de ambos os sexos. Variáveis como idade na cirurgia primária, tipo de cirurgia, cirurgião, terapia fonoaudiológica pós-operatória não foram controladas. A avaliação perceptivo-auditiva foi realizada utilizando gravação audiovisual durante a produção de três contextos de fala: conversa espontânea (CE), recontagem de estória (RE) e nomeação de figuras ou produção de vocábulos (NF). As gravações foram avaliadas por três fonoaudiólogos com experiência na área quanto a hipernasalidade, utilizando escala de 4 pontos (0=ausente, 1=leve, 2=moderado, 3=grave), e, emissão de ar nasal (EAN), fraca pressão intraoral (FPI) e erros articulatórios ativos (EAA), classificados como ausentes ou presentes. Concluída esta etapa, os juízes foram solicitados a emitir uma impressão global sobre a hipernasalidade (IGH), utilizando a mesma escala de 0 a 3. A concordância intra e interjuízes foi determinada para os escores de hipernasalidade das três amostras e para a IGH. A avaliação da nasalância foi realizada utilizando um nasômetro II-6450 (Kay Pentax), na produção de sílabas, vocábulos e sentenças. Os valores de nasalância foram comparados com valores normativos e a correlação entre a nasalância e nasalidade foi calculada para os vocábulos. A significância dos achados foi determinada para um nível de 5%. Resultados: Na avaliação perceptivo-auditiva da CE, observou-se, na maior parcela das crianças, ausência de hipernasalidade (70%) e, ausência de EAN (83%), FPI (83%) e EAA (74%). O mesmo foi observado para RE (65%; 78%; 83%; 65%) e NF (70%; 74%; 83%; 65%), respectivamente. Não houve diferença significante entre os escores atribuídos às quatro características de fala em CE, RE e NF. A concordância intra e interjuízes no julgamento da hipernasalidade foi, em sua maioria, quase perfeita ou perfeita nas três amostras e, também, na IGH. Na nasometria, foi de 62%, a porcentagem de valores sugestivos de ausência de hipernasalidade em sentenças orais (nasalância <27%). Na comparação com valores normativos os valores de nasalância no grupo com fissura do presente estudo foram significantemente maiores nas sílabas /pa/, /sa/, /la/ e /li/ e nas sentenças orais e nasais. A correlação entre nasalidade e nasalância foi de 74%. Conclusão: A avaliação perceptiva da fala mostrou que o tratamento de rotina oferecido pelo HRAC-USP foi efetivo na eliminação da hipernasalidade em cerca de 65 a 70% das crianças com fissura de palato isolada, mesmo considerando que importantes variáveis não tenham sido controladas no presente estudo. Os resultados foram confirmados na avaliação nasométrica. Os dados relatados podem ser utilizados como referência para estudos utilizando variáveis bem controladas. / Purpose: To evaluate the speech results of the surgical treatment of palatal clefting routinely performed in a specialized hospital unit, through perceptual and nasometric evaluation in children at 5 years of age. Methods: A prospective study was conducted in 27 children with isolated cleft palate previously repaired from a total sample of 52 children recruited in a 9 months time window, aged 4:8 to 5:6 years, of both genders. Variables such as age at primary surgery, type of surgery, surgeon, postoperative speech therapy were not controlled. The perceptual evaluation was performed using audiovisual recordings during the production three speech samples: spontaneous conversation (SC), story recounting (SR) and words production (WP). Recordings were evaluated by three experienced speech pathologists regarding severity of hypernasality, using a 4-point scale (0=absent, 1=mild, 2=moderate, 3=severe), nasal air emission (NAE), intraoral pressure (IOP) and active articulatory errors (AAE), classified as absent or present. At the end, the judges were asked to give an overall impression about hypernasality (OIH) also using the scale from 0 to 3. The intra- and interjudge agreement was determined for the hypernasality scores of the three speech samples and for OIH. Nasalance was assessed by using a KayPentax Nasometer II-6450 during the production of syllables, words and sentences. Nasalance values were compared with normative data and the correlation between nasality and nasalance was calculated for WP sample. The significance of diferences was determined at a level of 5%. Results: At the SC perceptual assessment, absence of hypernasality was observed in 70% of the children and absence of NAE in 83%, IOP in 83% and AAE in 74%. For SR, the rates were 65%, 78%, 83%, 65% and for NF, 70%, 74%, 83%, 65%, respectively. No significant differences were found among the scores attributed to the four speech characteristics in SC, SR and WP samples. Intra- and interjudge agreement for hypernasality scores was found to be mostly near perfect or perfect for all three samples and also for OIH. At nasometry, normal nasalance scores (<27%), suggesting absence of hypernasality in oral sentences were seen in 62% of the children. Compared to normative values from literature, nasalance scores were significantly higher for syllables /pa/, /sa/, /la/ and /li/ and also for oral and nasal sentences. The correlation between nasality and nasalance scores was 74%. Conclusion: Perceptual assessment of speech showed that the routine care was effective in eliminating hypernasality in about 65% to 70% of the children with isolated cleft palate, even though confounding variables were not controlled in the present study. Results were confirmed by nasometric assessment. The data obtained may be used as reference for studies using well-controlled variables.

Avaliação da condição de saúde bucal e o impacto na qualidade de vida de pacientes com doença renal crônica / &nbsp;

Maciel, Aloizio Premoli 26 March 2018 (has links)
Objetivos: Avaliar a saúde bucal e o seu impacto na qualidade de vida e indivíduos com doença renal crônica. Material e Métodos: Avaliamos um grupo de indivíduos com doença renal crônica sob hemodiálise e outro sem doença renal crônica, cada grupo com 100 participantes. Realizou-se avaliação odontológica e mensuração de índices de dentes cariados, perdidos e obturados, de edentulismo, sangramento gengival, placa dentária e o periodontal comunitário. Foi realizado sialometria mecanicamente estimulada e não estimulada para classificar a hipossalivação. Foi utilizado um questionário que avalia o impacto da saúde bucal na qualidade de vida, o OHIP-14, e outro que avalia o impacto negativo da qualidade de vida geral, o SF-36. Resultados: A xerostomia, disfagia, disgeusia, ardor bucal e dor bucal apresentaram prevalência significativa no grupo sob hemodiálise. As alterações bucais com prevalência significativa no grupo sob hemodiálise foram a saburra lingual, palidez da mucosa bucal, ressecamento bucal e labial, língua despapilada, candidíase bucal, abscessos periodontais agudos, halitose, língua fissurada e queilite actínica. A hipossalivação também foi mais prevalente no grupo sob hemodiálise. Os indivíduos com doença renal crônica demonstraram pior condição dentária e periodontal, e maior necessidade de uso de prótese dentária. Foi constatado um maior impacto mensurado pelo OHIP-14 total e na dimensão de limitação funcional no grupo sob hemodiálise. O impacto mensurado pelo SF-36 também foi mais significativo no grupo sob hemodiálise, porém foi expressivo em 7/8 domínios. A inflamação gengival e a necessidade de uso de prótese dentária foram correlacionados a maiores índices do OHIP-14 no grupo sob hemodiálise. A disgeusia, disfagia e ardor bucal foram associados ao aumento do OHIP-14 total e nas dimensões de limitação funcional, dor, desconforto psicológico, incapacidade física, psicológica e social deste mesmo questionário. A dor bucal foi correlacionada com o aumento do impacto da saúde bucal na qualidade de vida total e nas dimensões dor física, incapacidade social e desconforto psicológico. A única alteração bucal associada ao aumento do impacto mensurado pelo OHIP-14 foi o ressecamento labial que impactou na dimensão de incapacidade social. Diferentemente, o aumento do impacto mensurado pelo SF-36 foi associado à prevalência de candidíase eritematosa, saburra lingual, abscesso periodontal, ressecamento labial e língua fissurada, impactando negativamente domínios de capacidade funcional, vitalidade, aspectos sociais e mentais e saúde mental. Todas as dimensões mensuradas pelo OHIP-14 correlacionam-se com os domínios avaliados pelo SF-36, com exceção da capacidade funcional nos indivíduos sob hemodiálise. Conclusão: As manifestações bucais, juntamente com maiores índices de inflamação gengival e de necessidade de uso de prótese dentária foram correlacionadas e associadas com a piora na qualidade de vida no grupo com doença renal crônica, porém as queixas bucais pioraram diretamente a qualidade de vida relacionada com a boca e as lesões pioraram especificamente a qualidade de vida geral. As complicações bucais e sistêmicas que a doença renal crônica proporciona pioram a qualidade de vida através da saúde bucal e da saúde geral simultaneamente durante a realização de hemodiálise. / Aim: To evaluate the oral health condition and its impact in the quality of life of chronic kidney patients. Material and Methods: The sample of this study was divided into two groups, one group was composed by chronic kidney disease patients undergoing hemodialysis and the other group was composed by kidney healthy patients, each group contained 100 individuals. Individuals of both groups were submitted to standard odontological evaluation that included decayed, missing and filled index, evaluation of edentulism, gingival bleeding, dental plaque and community periodontal index. In order to evaluate the salivation, we applied unstimulated and stimulated saliva flow rate measurements. For the evaluation of the health-related quality of life impact we used the OHIP-14 profile index, and to estimate general quality of life we used the SF-36 questionnaire. Results: We found that xerostomia, dysphagia, dysgeusia and burning mouth sensation were significantly prevalent on chronic kidney patients. The most prevalent oral manifestations and lesions on those patients were oral candidiasis, acute periodontal abscess, dry lips, dry mouth, halitosis, smooth tongue, pale mucosa, fissured tongue, tongue coating, and actinic cheilitis. Hyposalivation was also observed to be more prevalent on chronic kidney patients. Dental and periodontal condition were poorer on chronic kidney patients and they had more need to use dental prothesis. We found a lower health-related quality of life total and in functional limitation dimension in chronic kidney patients. However, a lower general quality of life impact was estimated in 7/8 domains. Higher gingival and needs to use dental prothesis indexes were correlated to higher mensuration of OHIP-14 profile on chronic kidney patients. The dysphagia, dysgeusia and burning mouth sensation were associated to higher mensuration of OHIP-14 total and functional limitation, pain, psychological discomfort, physical, psychological and social disability dimension. The only oral manifestation associated with OHIP-14 profile was dry lips, increasing the social disability dimension. Differently, a higher impact evaluated for SF-36 was associated with prevalence of erythematous candidiasis, tongue coating, acute periodontal abscess, dry lips and fissured tongue, improving a higher negative impact in functional capacity, vitality, social and mental aspects and mental health domains. In chronic kidney patients all OHIP-14 dimensions were correlated with the SF-36 domains, exception to functional capacity. Conclusion: Oral manifestation, higher gingival inflammation index and prevalence of dental prosthesis use were correlated and associated to worsen health-related quality of life and general quality of life in chronic disease patients, but the symptoms impacted the health-related quality of life and the oral lesions and signs alterations specifically worsens general quality of life. The oral and systemic complications related to the chronic kidney disease negatively impacted the quality of life through the oral and general health simultaneously during the hemodialysis treatment.

Périco, Maíra de Souza 28 November 2013 (has links)
Objetivo: Verificar a concordância entre os resultados dos Testes de Emissão de Ar Nasal e de Hipernasalidade e os achados do exame de videofluorocopia no diagnóstico da disfunção velofaríngea, em indivíduos com fissura labiopalatina. Material e Método: A amostra foi constituída por 89 exames de videofluoroscopia e 89 escores dos Testes de Emissão de Ar Nasal e de Hipernasalidade, os quais foram interpretados ou como fechamento velofaríngeo consistente, ou como fechamento velofaríngeo inconsistente, ou como não fechamento velofaríngeo. Foram calculadas a sensibilidade, a especificidade e a concordância entre a interpretação dos achados dos testes perceptivos e os achados davideofluoroscopia. Resultados: Foram encontrados índices de sensibilidade e especificidade de 98% e 37%, respectivamente para o Teste de Emissão de Ar Nasal e de 96% e 63%, respectivamente para o Teste de Hipernasalidade. As porcentagens de concordância entre os escores do Teste de Emissão de Ar Nasal e os exames de videofluoroscopia e os do Teste de Hipernasalidade e os exames de videofluoroscopia para a categoria fechamento velofaríngeo consistente foi de 62% e 70%, respectivamente, para a de fechamento velofaríngeo inconsistente foi de 43% e 47%, respectivamente e para a de não fechamento velofaríngeo foi de 68% e 77%, respectivamente. Conclusão: Houve um bom nível de concordância entre os testes perceptivos e os exames de videofluoroscopia para as categorias fechamento velofaríngeo consistente e não fechamento velofaríngeo, mas não para a de fechamento velofaríngeo inconsistente. / Objetive: To determine the agreement between the results of the Nasal Air Emission and Hypernasality tests and the videofluoroscopy findings in the diagnosis of velopharyngeal dysfunction in individuals with cleft lip and palate. Material and Methods: The sample consisted of 89 scores of Nasal Air Emission and Hypernasality tests and 89 judgments of videofluoroscopy exam, which were interpreted as consistent velopharyngeal closure, or as inconsistent velopharyngeal closure, or as non velopharyngeal closure. The sensitivity, specificity and agreement between the interpretation of the results of the perceptual tests and the findings of the videofluoroscopy were calculated. Results: The rates found for sensitivity of Nasal Air Emission and Hypernasality tests were 98 and 96%, respectively, and the rates for specificity of Nasal Air Emission and Hypernasality tests were 37% and 63%, respectively. Regarding the percentages of agreement between the Nasal Air Emission test scores and the videofluoroscopy judgments, it was found agreement of 62% for the consistent velopharyngeal closure condition, 43% for the inconsistent velopharyngeal closure and 68% for the non velopharyngeal closure. Between the scores of Hypernasality test and videofluoroscopy judgments the agreement found was 70% for the consistent velopharyngeal closure condition, 47% for the inconsistent velopharyngeal closure and 77% for the non velopharyngeal closure. Conclusion: There was a good level of agreement between the perceptual tests and the videofluoroscopy judgments for the consistent velopharyngeal closure and non velopharyngeal closure conditions, but not for the inconsistent velopharyngeal closure.

Movimentação da velofaringe após o uso do obturador faríngeo / Velopharyngeal activity after use of speech bulb

Souza, Olívia Mesquita Vieira de 24 July 2009 (has links)
Introdução: Existem evidências clínicas de que os movimentos do mecanismo velofaríngeo (MVF) podem ser aumentados com o uso do obturador faríngeo a ponto de o mesmo ser descartado ou até que se consiga diminuir ao máximo o gap velofaríngeo. O aumento do movimento das paredes faríngeas torna o individuo um melhor candidato para correção cirúrgica da disfunção velofaríngea (DVF). Este aumento na atividade das paredes faríngeas, no entanto, não é um achado universal com o uso do obturador, principalmente para aqueles pacientes que apresentam articulações compensatórias ou que apresentam velofaringe hipodinâmica. Objetivo: O presente estudo tem por objetivo avaliar o movimento das estruturas do MVF durante a fala, em pacientes que apresentam insuficiência velofaríngea (IVF) e que fazem uso de obturador faríngeo. A avaliação foi realizada antes (C1) e após pelo menos seis meses de uso do mesmo (C2). Material e Método: A casuística foi constituída de 25 pacientes, com fissura de palato e/ou de lábio e palato (8 mulheres e 17 homens), com idades variando entre 20 e 47 anos (média= 36 anos). Todos os pacientes apresentavam IVF após a cirurgia de palato e utilizavam obturador faríngeo havia pelo menos 6 meses. Para a avaliação do MVF com e sem o obturador faríngeo, todos pacientes haviam sido submetidos à avaliação nasoendoscópica durante fala. As 50 video-gravações dos exames de nasoendoscopia (25 na condição C1 e 25 na condição C2) foram editadas em um DVD e avaliadas por três fonoaudiólogas experientes, designadas juízas, quanto aos seguintes aspectos: movimento do véu palatino, movimento das paredes laterais da faringe, tamanho e tipo do gap velofaríngeo e anel de Passavant. Para a avaliação foi utilizado o protocolo proposto por Golding-Kushner et al (1990), especialmente adaptado para este estudo. Resultados: Neste estudo o grau de concordância intra-juízas foi de 82% para a juíza A, e 62% para as juízas B e C, para todos os aspectos do MVF avaliados. Já o grau de concordância inter-juízas variou de 49 a 88%, com média de 69%. Apesar de não terem sido encontradas diferenças estatisticamente significantes entre as condições C1 e C2, observamos que 17 (68%) dos 25 pacientes avaliados apresentaram diferenças na atividade muscular em pelo menos um dos 11 aspectos estudados. Conclusão: Os achados deste estudo demonstraram mudanças na atividade velofaríngea sugerindo que o uso do obturador faríngeo no tratamento da DVF pode ser útil tanto no processo de diagnóstico (para identificação do potencial de mudança no funcionamento velofaríngeo e na fala) quanto durante o tratamento da IVF (otimizando os resultados cirúrgicos). / Introduction: There are clinical evidence that movements of velopharyngeal mechanism can be increased with the use of speech bulbs to the point of elimination of the bulbo or until the maximum reduction of the velopharyngeal gap is achieved. An increase in the movements of pharyngeal wall turns the individual to a better candidate for surgical correction of velopharyngeal dysfunction (VPD). An increase in the activity of pharyngeal walls, however, is not an universal finding for all individual with speech bulbs, particularly for those Who use compensatory articulation or that present hypodynamic velopharynx.Objective: The present study has the objective of evaluate movement of the velopharyngeal structures during speech in patients with velopharyngeal insufficiency using speech bulbs. The evaluation was done before (C1) and at least 6 months after use of the bulb (C2).Material and Methods: The sample included 25 patients with cleft palate and/or cleft lip and palate (8 males and 17 females), with ages varying between 20 and 47 years (mean=36 years). All patients presented with velopharyngeal insufficiency and were using speech bulbs for at least 6 months. For the evaluation of the velopharyngeal mechanism with and without the speech bulb, all patients were submitted to nasoendoscopic evaluation during production of speech. All 50 video-recordings (25 in the C1 condition and 25 in the C2 condition) were edited into a DVD and evaluated by three experienced speech-language pathologists who judged the samples regarding the following aspects: movement of velum, movement of pharyngeal walls, type and size of velopharyngeal gap and Passavants Pad. For this study was used the protocol proposed by Golding-Kushner et al (1990), specially adapted for this evaluation.Results: In this study intra-judge agreement of 82% was found for judge A, and 62% for judges B and C, when all aspects rated were considered. Inter-judge agreement varied between 49% and 88% with a mean of 69%. Even though a significant difference was not found between the pré and pot speech bulb conditions, 17 (68%) subjects presented with differences in velopharyngeal activity in at least on of the 11 aspects studied. Conclusion: The findings of this study demonstrated changes in the velopharyngeal activity suggesting that the use of speech bulbs during treatment of VPD can help the diagnostic process (in the identification of the potential for changes of velopharyngeal functioning and of speech) and also can help in the treatment (by optimizing surgical results).

Resultados de fala e de função velofaríngea do retalho faríngeo e da veloplastia intravelar na correção da insuficiência velofaríngea: estudo comparativo / Speech and velopharyngeal function outcomes of pharyngeal flap and intravelar veloplasty for velopharyngeal insufficiency management: a comparative study

Barbosa, Daniela Aparecida 25 March 2011 (has links)
Objetivo: Investigar a efetividade da cirurgia de retalho faríngeo (RF) e da palatoplastia secundária com veloplastia intravelar (VI) na correção da insuficiência velofaríngea (IVF) e comparar os resultados pós-cirúrgicos de hipernasalidade, hiponasalidade, nasalância e grau de fechamento velofaríngeo entre as duas cirurgias. Material e Métodos: Estudo conduzido no Laboratório de Fisiologia do HRAC-USP, em 78 indivíduos, de ambos os sexos, com idade entre 6 e 52 anos (21±10 anos, em média), com fissura de palato±lábio, já submetidos à correção cirúrgica da IVF há 14 meses, em média, sendo 40 pacientes com RF e 38 com VI. A hipernasalidade e a hiponasalidade foram classificadas perceptivamente por três fonoaudiólogas a partir de amostra de fala gravada. A nasalância foi determinada por meio da nasometria e o fechamento velofaríngeo foi aferido a partir da medida da área do orifício velofaríngeo obtida por meio da avaliação aerodinâmica. Diferenças entre as duas técnicas foram consideradas estatisticamente significantes ao nível de 5%. Resultados: Verificou-se ausência de hipernasalidade em 35% e 70% dos casos e, presença de hiponasalidade em 10% e 25% dos pacientes com RF, de acordo com a avaliação perceptiva da fala e a nasometria, respectivamente e, fechamento velofaríngeo adequado em 80% dos casos, de acordo com a avaliação aerodinâmica. Nos pacientes com VI, ausência de hipernasalidade foi verificada em 29% e 34% e hiponasalidade foi detectada em 3% dos casos, respectivamente na avaliação perceptiva da fala e na nasometria e, fechamento velofaríngeo adequado foi observado em 50% dos pacientes. Conclusão: O retalho faríngeo foi mais eficiente que a palatoplastia secundária com veloplastia intravelar na eliminação dos sintomas da IVF. / Objective: To investigate the effectiveness of pharyngeal flap surgery (PFS) and the secondary palatoplasty with intravelar veloplasty (IV) for velopharyngeal insufficiency management (VPI) as well as to compare the postoperative outcome of hypernasality, hyponasality, nasalance and velopharyngeal closure between the two surgeries. Methods: Study conducted at the Laboratory of Physiology, HRAC-USP, on 78 individuals of both genders, aged between 6 and 52 years (21±10 years, on average), with cleft palate±lip , underwent surgical management of IVF for 14 months on average, 40 patients with RF and 38 with IV. Hypernasality and hyponasality were perceptually rated by three speech pathologists using recorded speech samples. Nasalance was determined by means of nasometry and velopharyngeal closure was assessed by means of velopharyngeal orifice area measurement provided by pressure-flow studies. Differences between the two techniques were considered statistically significant at 5%. Results: Absence of hypernasality was observed in 35% and 70% of the cases, and presence of hyponasality in 10% and 25% of the patients submitted to RF, according to the perceptual speech assessment and nasometry, respectively, and adequate velopharyngeal closure was observed in 80% of the cases, according to the aerodynamic evaluation. Absence of hypernasality in patients submitted to VI, was observed in 29% and 34%, and hyponasality was detected in 3% of the cases, respectively according to the perceptual speech assessment and nasometry, and adequate velopharyngeal closure was observed in 50% of these patients. Conclusion: The pharyngeal flap surgery was more efficient than the secondary palatoplasty with intravelar veloplasty regarding the elimination of IVF symptoms.

Identificação dos compostos sulfurados voláteis em indivíduos com doença renal crônica e seu impacto na qualidade de vida / Volatile sulfur compounds identification in individuals with chronic kidney disease and their impact on quality of life

Santaella, Natalia Garcia 27 February 2019 (has links)
O objetivo foi identificar os compostos sulfurados voláteis (CSVs) em indivíduos com doença renal crônica e relacionar com o teste organoléptico, índices de saúde bucal, questionários de qualidade de vida e pH salivar. A amostra foi constituída de indivíduos com doença renal crônica (GE) sob hemodiálise e indivíduos saudáveis (GC). Foi realizada a identificação dos CSVs com o cromatógrafo gasoso OralChroma antes (SC) e após bochecho com cisteína (CC), teste organoléptico, índice de dentes cariados, perdidos e obturados (CPO), índice gengival, índice de placa, índice periodontal comunitário e índice de edentulismo, sialometria em repouso e mecanicamente estimulada, questionário do impacto da saúde bucal na qualidade de vida (OHIP-14), impacto da saúde geral na qualidade de vida (SF-36) e inventário de xerostomia. Como resultados, sulfidreto CC (p<0,0001) e metilmercaptana CC (p = 0,005) foram significativamente maiores no GE. Houve correlação do sulfidreto (r = ,442 e p = 0,016) e do metilmercaptana (r = ,409 e p = 0,028) SC com a profundidade de bolsa 4-5mm. O composto que mais afetou o teste organoléptico foi o sulfidreto SC. A frequência de boca seca, sialometria em repouso e mecanicamente estimulada foram significativamente maiores no GE. Nenhum dos CSVs afetaram negativamente o impacto da saúde bucal na qualidade de vida no GE mas, sim no GC. Os CSVs não causaram impacto da saúde bucal no GE, mas sim no GC, onde o metilmercaptana CC piorou o impacto na dimensão incapacidade psicológica (r = 0,365 e p = 0,040). Já no impacto da saúde geral na qualidade, o composto metilmercaptana SC (r = -,410 e p = 0,020) e CC (r = -,379 e p = 0,033) piorou a saúde geral nas dimensões vitalidade e saúde mental, respectivamente. Não houve relação dos CSVs com as variáveis relacionadas à DRC. Em conclusão, indivíduos com doença renal crônica possuem mais halitose que indivíduos saudáveis. Esta halitose está mais relacionada ao metilmercaptana. Apesar da halitose não ter afetado negativamente na qualidade de vida relacionado a saúde bucal, piorou a qualidade de vida geral nas dimensões vitalidade e estado de saúde mental dos indivíduos com DRC. A cisteína é importante no diagnóstico da halitose. / The purpose of this study was to identify volatile sulfur compounds (VSC) in individuals with chronic kidney disease (CKD) and to relate to the organoleptic test, oral health indexes, quality of life questionnaires and salivary pH. The sample consisted of individuals with chronic kidney disease (SG) under hemodialysis and healthy individuals (CG). The VSC were identified with OralChroma gas chromatograph before (BC) and after cysteine mouthwash (AC), organoleptic test, decayed, missing and filled teeth (DMFT), gingival index, plaque index, community periodontal index and evaluation of edentulism, tongue coating Oral Health Impact Profile (OHIP-14), impact of general health on quality of life with Medical Outcomes Study 36-Item Short Form Health Survery (SF-36), and xerostomia inventory. The hydrogen sulphide AC, methyl mercaptan AC, tongue coating, dry mouth sensation, DMFT and need for upper and lower prostheses were significantly higher in the SG, bleeding index was significantly higher in the CG. As a result, hydrogen sulphide AC (p <0.0001) and methyl mercaptan AC (p = 0.005) were significantly higher in SG. There was a correlation between sulfhydride (r =, 442 ep = 0.016) and methyl mercaptan (r =, 409 ep = 0.028) SC with probing depth 4-5mm. The most affected organoleptic test was SC sulfhydride. The frequency of dry mouth, resting and mechanically stimulated sialometry were significantly higher in SG. None of the CSVs negatively affected the impact of oral health on the quality of life in the SG but in the CG. VSCs had no impact on oral health in SG, but on CG, where methyl mercaptan AC worsened the impact on the psychological disability dimension (r = 0.365 and p = 0.040). As for the impact of general health on quality, the BC methyl mercaptan compound (r = -, 410 and p = 0.020) and WC (r = -, 379 and p = 0.033) worsened overall health in vitality and mental health, respectively. There was no relation of the VSC with the variables related to CKD. In conclusion, individuals with chronic kidney disease have more halitosis than healthy individuals. This halitosis is more related to methyl mercaptan. Although halitosis did not negatively affect quality of life related to oral health, it worsened overall quality of life in the vitality and mental health status of individuals with CKD. Cysteine is important in the diagnosis of halitosis.

Genome damage and folate nutrigenomics in uteroplacental insufficiency.

Furness, Denise Lyndal Fleur January 2007 (has links)
Pregnancy complications associated with placental development affect approximately one third of all human pregnancies. Genome health is essential for placental and fetal development, as DNA damage can lead to pregnancy loss and developmental defects. During this developmental phase rapid DNA replication provides an increased opportunity for genome and epigenome damage to occur[1]. Maternal nutrition is one of the principal environmental factors supporting the high rate of cell proliferation and differentiation. Folate functions in one-carbon metabolism and regulates DNA synthesis, DNA repair and gene expression[1]. Deficiencies or defects in gene-nutrient interactions associated with one-carbon metabolism can lead to inhibition of cell division, cell cycle delay and an excessive apoptotic or necrotic cell death rate [2], which may affect placentation. This study is the first to investigate the association between genomic damage biomarkers in late pregnancy complications associated with uteroplacental insufficiency (UPI) including preeclampsia and intrauterine growth restriction (IUGR). The results indicate that genome damage in the form of micronucleated cells in peripheral blood lymphocytes at 20 weeks gestation is significantly increased in women at risk of developing an adverse pregnancy outcome. The observed OR for the high micronuclei frequency may be the highest observed for any biomarker selected in relation to risk of pregnancy complications to date (15.6 – 33.0). In addition, reduced apoptosis was observed in association with increased micronuclei, suggesting that the cells may have escaped specific cell-cycle checkpoints allowing a cell with DNA damage to proceed through mitosis. This study demonstrated that an increase in plasma homocysteine concentration at 20 weeks gestation is associated prospectively with the subsequent development of UPI, indicating a causal relationship. The MTR 2756 GG genotype was significantly associated with increased plasma homocysteine concentration and UPI. Furthermore, the MTHFD1 1958 single nucleotide polymorphism was associated with increased risk for IUGR. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1309296 / Thesis (Ph.D.) -- School of Paediatrics and Reproductive Health, 2007

Varicose Veins : Aspects on Diagnosis and Surgical Treatment

Blomgren, Lena January 2005 (has links)
<p>Treatment for varicose veins (VV) is insufficiently evidence based and recurrence rates are high.
