Electrophysiological characterization of hearing in individuals with Down syndrome. / Caracterização eletrofisiológica da audição em indivíduos com Síndrome de Down.

INTRODUCTION: Few studies have performed Brainstem (BAEP) and P300 Auditory Evoked Potentials simultaneously to assess central auditory pathways in normal hearing individuals with Down syndrome (DS), mainly because of the difficulty in applying these procedures to this population. Previous studies have suggested that individuals with DS might present different patterns of response compared with those of individuals with typical development; nevertheless, the identification of these potentials would be crucial for the establishment of an accurate audiological diagnosis. PURPOSE: To characterize BAEP and P300 in normal-hearing individuals with DS. METHODS: BAEP and P300 were analyzed in 17 individuals with DS and in 21 individuals with typical development aged 7 to 15 years. The results were quantitatively and qualitatively analyzed using descriptive measures and hypothesis tests. RESULTS: In the quantitative analysis, latency values were lower in the BAEP for the DS group, with statistically significant difference for wave V and interpeaks III-V and I-V; there were no significant differences in the P300 latency values. In the qualitative analysis, there were a larger number of individuals with early values for BAEP latencies and late latencies for P300 in the DS group; both comparisons showed statistically significant differences. CONCLUSION: Children and adolescents with DS can present early responses to the components of BAEP, suggesting that their auditory pathway requires less time for the neural transmission of acoustic stimuli to the brainstem. Concerning P300, individuals with DS may present increased latencies, suggesting impairment in the central auditory pathway for the cortical processing of auditory information.

Caracterização eletrofisiológica da audição em indivíduos com Síndrome de Down / Electrophysiological characterization of hearing in individuals with Down syndrome

RESUMO Introdução Poucos estudos realizaram, concomitantemente, o potencial evocado auditivo de tronco encefálico (PEATE) e o P300 na Síndrome de Down (SD), em indivíduos audiologicamente normais, para a avaliação da via auditiva central, principalmente pela dificuldade de realizar estes procedimentos nesta população. Estudos anteriores sugeriram que indivíduos com SD podem apresentar padrões de respostas diferentes das encontradas em indivíduos com desenvolvimento típico, sendo que a identificação destes seria fundamental para o estabelecimento de um diagnóstico audiológico preciso. Objetivo Caracterizar o PEATE e o P300 em indivíduos com SD audiologicamente normais. Método Foram analisados o PEATE e o P300 de 17 indivíduos com SD e 21 com desenvolvimento típico de sete a 15 anos. A análise foi quantitativa e qualitativa, utilizando medidas descritivas e os testes de hipótese. Resultados Os valores de latência foram menores no PEATE para o grupo SD, com diferença estatisticamente significante para a onda V, interpicos III-V e I-V; não foram encontradas diferenças significantes nos valores de latência do P300. Observou-se maior número de indivíduos com valores precoces para as latências do PEATE e com latências atrasadas para o P300 no grupo SD; ambas as comparações mostraram diferenças significantes. Conclusão Crianças e adolescentes com SD podem apresentar respostas precoces para os componentes do PEATE, sugerindo que a via auditiva destes necessita de menor tempo para a transmissão neural do estímulo acústico até o tronco encefálico. Quanto ao P300, indivíduos com SD podem apresentar latências aumentadas, sugerindo comprometimento na via auditiva central quanto ao processamento cortical da informação auditiva.

Wideband reflectance in Down syndrome.

OBJECTIVE: Children with Down syndrome (DS) have a high incidence of middle ear disorders and congenital abnormalities of the external, middle and inner ear. Energy reflectance (ER), a wideband acoustic immittance (WAI) measurement parameter, can measure the sound energy reflected or absorbed in the ear canal over a wider range of frequencies more efficiently and faster than conventional single-tone 226 Hz tympanometry. The aim of the present study was to compare the WAI measurements of children with DS with those of typically developing, normal-hearing children according to their tympanometric findings. METHODS: Four groups of children with Down syndrome (age range: 2 years and 4 months to 16 years and 3 months; mean age: 8.5 yr) with normal tympanograms (19 ears), flat tympanograms (13 ears), mild negative pressure tympanograms (6 ears between -100 and -199 daPa at the admittance peak) and severe negative pressure tympanograms (4 ears at -200 daPa or lower at the admittance peak) were assessed. All findings were compared with data obtained from 21 ears of a healthy control group (age range: 3 years and 1 month to 13 years and 11 months; mean age: 7.9 yr). The subjects underwent tympanometry with a 226-Hz probe tone frequency and ER measurements along the 200-6,000 Hz range with a chirp stimulus using the Middle-Ear Power Analyzer (MEPA3 - HearID) by Mimosa Acoustics (Champaign, IL), software, version 3.3 [38]. RESULTS: Statistically significant differences were observed in the ER curves for some comparisons between the studied groups. There was also a negative correlation between the static acoustic admittance at the tympanic membrane level and ER measured with a chirp stimulus at 500 and 1,000 Hz. The discriminant analysis technique, which used a chirp stimulus at 1,000 and 1,600 Hz to classify the participants' data based on ER values, achieved a correct classification rate of 59.52% for participants with DS. CONCLUSION: While groups with abnormal middle ear status, as indicated by tympanometry, showed higher ER values compared to the DS tymp A group and the control group, similar reflectance curves were observed between control group and the DS tymp A group. WAI shows promise as a clinical diagnostic tool in investigating the impact of middle ear disorders in DS group. However, further research is required to investigate this issue in narrower age range group and a larger sample size.

Dietary transition difficulties in preterm infants: critical literature review / Dificuldades de transição alimentar em crianças prematuras: revisão crítica de literatura

ABSTRACT OBJECTIVE: To analyze the scientific literature on dietary changes in preterm children during the first years of life. DATA SOURCE: The PubMed database was used for article selection. The texts were analyzed according to their objectives, research design, and research group characteristics. The following were selected to comprise the criteria: (1) publications in the period from 1996 to 2014; (2) participation of infants and children from birth to 10 years of age; (3) development of oral motor skills necessary for feeding; (4) development of the feeding process; and (5) feeding difficulties during childhood. SUMMARY OF THE FINDINGS: There were 282 studies identified, of which 17 were used in the review, and five more articles were identified through the reference list of selected articles, totaling 22 references. CONCLUSION: Very low birth weight preterm newborns are more likely to have feeding problems in early postnatal stages and during childhood when compared with full-term infants. Monitoring the feeding of these infants after hospital discharge is strictly recommended in an early intervention program aiming at better development of feeding skills.

RESUMO OBJETIVO: Analisar a literatura científica sobre alterações alimentares em crianças prematuras durante os primeiros anos de vida. FONTE DOS DADOS: A base de dados do Pubmed foi a precursora para a seleção dos artigos. Os textos foram analisados quanto aos seus objetivos, desenhos da pesquisa e características do grupo pesquisa e foram selecionados os seguintes temas para compor os critérios: (1) publicações de 1996 a 2014; (2) participação de bebês e crianças, do nascimento até os 10 anos; (3) desenvolvimento das habilidades motoras orais necessárias para a alimentação; (4) desenvolvimento do processo de alimentação e (5) dificuldades alimentares durante a infância.

Comparison between clinical and videofluoroscopic evaluation of swallowing in children with suspected dysphagia.

PURPOSE: To verify the accuracy of clinical evaluation compared with videofluoroscopic swallowing studies in the detection of isolated laryngeal penetration and laryngeal aspiration in children with suspected dysphagia; to identify clinical signs and symptoms associated with isolated laryngeal penetration and laryngeal aspiration; and to determine the sensitivity and specificity of the clinical signs and symptoms identified. METHODS: Retrospective analysis of data from clinical and videofluoroscopic evaluations carried out in 55 children from 1 month to 7 years and 11 months old. For clinical assessment, the Protocol for Clinical Assessment of Pediatric Dysphagia was used. The sensitivity, specificity, and positive and negative predictive values of clinical evaluation were analyzed. For statistical analysis, the Fisher's exact and χ2 tests were used. RESULTS: Clinical evaluation showed, in general, a sensitivity of 86% and a specificity of 32%. For isolated laryngeal penetration, clinical evaluation showed a sensitivity of 88%. For laryngeal aspiration, clinical evaluation showed a sensitivity of 86%. However, the specificity values were low for both alterations. There was no association between clinical evaluation and videofluoroscopic findings. Choking was the only clinical sign associated with isolated laryngeal penetration thin fluid and showed a sensitivity of 53% and a specificity of 77%. CONCLUSIONS: Clinical evaluation was sensible to detect isolated laryngeal penetration and laryngeal aspiration in children with suspected dysphagia. However, it showed a low specificity. Choking was the only clinical sign associated with isolated laryngeal penetration of thin fluid. More prospective studies are needed to confirm these findings in this population.

Métodos: Análise retrospectiva de dados de avaliações clínicas e videofluoroscópicas realizadas em 55 crianças de 1 mês a 7 anos e 11 meses de idade. Na avaliação clínica foi utilizado o Protocolo de Avaliação Clínica da Disfagia Pediátrica. Foram analisados: sensibilidade, especificidade e valores preditivos positivo e negativo da avaliação clínica. Também foram utilizados os testes exato de Fisher e do χ2 na análise estatística. Resultados: A avaliação clínica apresentou, no geral, sensibilidade de 86% e especificidade de 32%. Para penetração laríngea isolada, a avaliação clínica apresentou sensibilidade de 88%. Para aspiração laríngea, a avaliação clínica apresentou sensibilidade de 86%. Contudo, os valores da especificidade foram baixos para ambas as alterações. Não houve associação significativa entre a avaliação clínica e os achados videofluoroscópicos. O engasgo foi o único sinal clínico associado à penetração laríngea isolada com líquido fino e apresentou sensibilidade de 53% e especificidade de 77%. Conclusões: A avaliação clínica foi sensível para detectar penetração laríngea isolada e aspiração laríngea em crianças com suspeita de disfagia, porém, apresentou baixa especificidade. O engasgo foi o único sinal clínico associado à penetração laríngea isolada com líquido fino. São necessários mais estudos prospectivos que confirmem esses achados nessa população. .

Ultrassonografia e deglutição: revisão crítica da literatura / Ultrasonography and swallowing: a critical review of the literature

Objetivo Identificar como a função da deglutição tem sido avaliada por meio da ultrassonografia (USG). Estratégia de pesquisa Esta revisão da literatura levantou publicações científicas internacionais sobre a USG e seu uso na avaliação da deglutição, por meio da base de dados PubMed. Foi realizada a localização e seleção dos estudos através de levantamento de textos publicados sobre o assunto, no período de janeiro de 2002 a agosto de 2013, limitando-se a estudos em seres humanos, no idioma inglês. Critérios de seleção Foram excluídos aqueles repetidos por sobreposição das palavras-chave, estudos de caso, revisões de literatura, cartas ao editor e os não relacionados diretamente à temática. Resultados Foram identificados 17 estudos que corresponderam aos critérios de inclusão. Observou-se que mais da metade dos estudos avaliou a deglutição de indivíduos adultos saudáveis, sem preferência por nenhum dos gêneros. Os parâmetros adotados para a análise das imagens não foram unânimes, havendo variação considerável entre os estudos. Conclusão A USG da deglutição demonstrou ser um método rápido, não invasivo, de baixo custo, que fornece parâmetros objetivos sobre a deglutição e que pode ser realizado em beira de leito, uma vez que o equipamento costuma ser de fácil manuseio e transporte. .

Purpose To identify how the deglutition function has been evaluated using ultrasound (US). Research strategy This literature review used the PubMed database to survey international scientific publications about US and its use to evaluate deglutition. Studies were located and selected by surveying relevant articles published between January 2002 and August 2013. The survey was limited to studies on humans published in English. Selection criteria Repeated studies (determined by overlapping keywords), case studies, literature reviews, letters to the editor and studies not directly related to the topic were excluded. Results A total of 17 studies matching the inclusion criteria were identified. More than half of the studies evaluated the deglutition of healthy adults with no preference for gender. The parameters adopted for image analysis were not unanimous, and there was considerable variation among studies. Conclusion US proved to be a fast, non-invasive, low-cost method for evaluating objective parameters of deglutition. As a further advantage, US may be performed at bedside because the equipment is typically easy to handle and transport. .

Laryngeal cleft type I in neonate: case report.

Laryngeal cleft (LC) is a congenital malformation that leads to the unusual communication between the esophagus and the laryngotracheal complex. It is a rare disease, mostly prevalent among male individuals. The goal of this study was to describe the evaluation and intervention by the speech language pathologist of a female newborn diagnosed with LC type I, admitted on the University Hospital of Universidade de São Paulo, in her second hospitalization due to small weight gain and pneumonia. She was submitted to a bedside clinical evaluation of the swallowing and the most important occurrence was frequent gagging. The videofluoroscopy swallowing study showed laryngotracheal aspiration level 8 for thin liquid and level 1 for thickened liquid, according to the Penetration-Aspiration Scale. The newborn was submitted to a microlaryngoscopy, in which the presence of LC type I was found. After the diagnosis, the speech language pathologist offered thickened liquid at 6% and, in 8 days, the newborn was discharged with exclusive oral diet without gagging. Eight outpatient consultations were carried out for 11 months, with emphasis on reintroduction of thin liquids. The treatment was discontinued and the patient was put on general diet for the age without modifications. Throughout follow-up, the patient remained asymptomatic and showed no respiratory complications.

O cleft laríngeo (CL) é uma malformação congênita que resulta em uma incomum comunicação entre esôfago e o complexo laringotraqueal. É uma doença rara, de maior prevalência no gênero masculino. O objetivo deste estudo foi relatar a atuação fonoaudiológica em um caso de um paciente neonato com diagnóstico de CL tipo I, admitido no Berçário do Hospital Universitário da Universidade de São Paulo, em sua segunda internação por baixo ganho ponderal e quadro de pneumonia. Foi realizada a avaliação clínica da disfagia infantil em beira de leito, cuja principal ocorrência foi a presença de engasgos frequentes. O exame de videofluoroscopia da deglutição evidenciou presença de aspiração laringotraqueal escore 8 para líquido fino e escore 1 para líquido engrossado, segundo a Escala de Penetração-Aspiração. O neonato foi submetido a microlaringoscopia, na qual foi constatada a presença de CL tipo I. Após o diagnóstico, a conduta fonoaudiológica foi de engrossar a fórmula láctea a 6% e, em oito dias, o neonato recebeu alta com dieta exclusiva por via oral, com ausência de engasgos. Foram realizadas oito consultas ambulatoriais durante 11 meses de acompanhamento, com ênfase na reintrodução de líquidos finos. A paciente recebeu alta fonoaudiológica com dieta geral para a idade, sem modificações. Durante todo o gerenciamento, a paciente permaneceu assintomática e não apresentou quadros respiratórios.

Avaliação auditiva periférica em crianças com síndrome de Down / Peripheral hearing evaluation in children with Down syndrome

Objetivo Caracterizar o sistema auditivo periférico de indivíduos com síndrome de Down, por meio da audiometria convencional e de altas frequências. Métodos Estudo do tipo transversal e observacional. Participaram 15 indivíduos com síndrome de Down, de ambos os gêneros, entre 7 e 15 anos de idade. Foram realizados os seguintes procedimentos: Meatoscopia, Timpanometria com pesquisa do reflexo acústico ipsilateral e contralateral, Audiometria Tonal, Audiometria Vocal e Audiometria de Altas Frequências. Resultados Houve predomínio de perda auditiva condutiva de grau leve, em uma ou ambas as orelhas. As médias dos limiares auditivos para a audiometria convencional ficaram abaixo de 20 dBNA e, para a audiometria de altas frequências, ficaram entre 20 e 40 dBNA. O coeficiente de correlação de Pearson revelou correlação moderada positiva, entre os limiares de 9 a 14 kHz e a idade. Conclusão De forma geral, não foram observadas diferenças significativas, quando comparadas as orelhas direita e esquerda de indivíduos com síndrome de Down, na audiometria tonal, imitanciometria e logoaudiometria. A maioria das crianças apresentou alteração de orelha média e perda auditiva condutiva. A audiometria de altas frequências sugere o início de prejuízo da função coclear, que pode estar associado às otites médias frequentes e/ou à degeneração coclear precoce. .

Purpose This study sought to characterize the peripheral auditory system of individuals with Down syndrome (DS) using conventional and high-frequency audiometry. Methods We performed a cross-sectional and observational study. Fifteen individuals with DS, who were of both genders and between 7 and 15 years of age, participated in this study. The following procedures were performed: otoscopy, tympanometry with ipsilateral and contralateral acoustic reflex, pure-tone audiometry, vocal audiometry and high-frequency audiometry. Results There was a predominance of mild conductive hearing loss in one or both ears. The mean hearing thresholds for conventional audiometry were below 20 dB HL and between 20 and 40 dB HL for high-frequency audiometry. The Pearson correlation coefficient indicated a moderate positive correlation between the 9-14 kHz thresholds and age. Conclusion Overall, no significant differences were observed when comparing the right and left ears of individuals with DS, in regards to pure-tone audiometry, immittance testing and speech audiometry. Most children showed middle ear abnormalities and conductive hearing loss. Moreover, high-frequency audiometry suggested the onset of impaired cochlear function, which may be associated with frequent otitis media episodes and/or early cochlear degeneration. .

Mean length utterance in Brazilian children: a comparative study between Down syndrome, specific language impairment, and typical language development.

PURPOSE: To describe the linguistic performance of Brazilian Portuguese-speaking children with Down syndrome by analyzing their Mean Length Utterance; to compare their performance to that of children with Specific Language Impairment and Typical Development; and to verify whether children with Down syndrome present developmental language delay or disorder. METHOD: Participants were 25 children with Down syndrome (Research Group), matched by mental age to a Control Group of typically developing children, and to a Control Group of children with Specific Language Impairment. Participants were divided into subgroups, according to age range (three, four and five years). Speech samples were collected for the Research Group, and the Mean Length Utterance was analyzed for morphemes and words. RESULTS: Differences were observed between the performance of the Research Group and both Control Groups, and the former presented inferior Mean Length Utterance values for all age ranges, characterizing a delay in grammar and general language development. CONCLUSION: The description of the linguistic abilities of Brazilian Portuguese-speaking children with Down syndrome indicated important grammatical deficits, especially regarding the use of functional words.

OBJETIVO: Descrever o desempenho linguístico de crianças com síndrome de Down falantes do Português Brasileiro por meio da análise da Extensão Média do Enunciado, comparar esse desempenho ao de crianças com Distúrbio Específico de Linguagem e com Desenvolvimento Típico e verificar se as crianças com síndrome de Down apresentam atrasos ou desvios do desenvolvimento linguístico. MÉTODO: Participaram do estudo 25 crianças com síndrome de Down (grupo pesquisa), pareadas pela idade mental ao grupo controle de crianças com desenvolvimento típico e ao grupo controle de crianças com Distúrbio Específico de Linguagem. Os participantes foram divididos em subgrupos de acordo com a faixa etária (três, quatro e cinco anos). Foram colhidas amostras de fala do grupo pesquisa e realizadas análises por meio da Extensão Média do Enunciado medida em morfemas e em palavras. RESULTADOS: Observaram-se diferenças de desempenhos entre o grupo pesquisa e os grupos controle, sendo que o primeiro apresentou valores de Extensão Média do Enunciado inferiores em todas as faixas etárias, o que caracteriza o atraso do desenvolvimento gramatical e linguístico geral. CONCLUSÃO: A descrição das habilidades linguísticas de crianças com síndrome de Down falantes do Português Brasileiro apontou para déficits gramaticais importantes, principalmente no que se refere ao uso de palavras funcionais. .

O uso da comunicação suplementar e/ou alternativa no trabalho com a morfossintaxe em adolescentes com Síndrome de Down / The use of augmentative and alternative communication in morphosyntax intervention in adolescents with Down Syndrome

Objetivo apresentar e discutir o uso de comunicação suplementar e/ou alternativa como instrumento terapêutico no trabalho com a morfossintaxe em adolescentes com síndrome de Down. Métodos estudo piloto que acompanhou longitudinalmente (doze meses) quatro adolescentes com idade cronológica entre 13 e 15 anos e idade mental entre cinco e seis anos. Foram consideradas as avaliações inicial e final, filmadas durante 30 minutos em situação de interação livre entre participante e cuidador. As amostras de fala foram analisadas a partir do cálculo da EME, quanto morfemas e palavras, para comparação entre as avaliações. Durante a intervenção terapêutica, todos os participantes foram submetidos ao mesmo procedimento. Foi utilizado o Picture Communication Symbols (PCS), com os símbolos ordenados seguindo uma estrutura sintática simples (substantivo + verbo + complemento), ampliada gradativamente,na seguinte ordem de elementos: artigos, preposições, pronomes (pessoais, possessivos e demonstrativos) e conjunções. Cada sessão terapêutica foi registrada em protocolo específico. Foi realizado o teste de Wilcoxon e o nível de significância adotado foi de 5%. Resultados apesar de não ter sido obtida diferença estatisticamente significante, houve aumento do número de morfemas e de palavras entre as duas avaliações, representados pelos elementos trabalhados, incluindo preposições e conjunções, além de substantivos e verbos. Para pronomes pessoais foi verificada tendência à significância (p=0,068). Conclusão o sistema de comunicação adotado mostrou-se uma ferramenta apropriada ao favorecimento do emprego de estruturas frasais com o uso de elementos com função sintática, como artigos, preposições ...

Purpose to present and to discuss the use of augmentative and alternative communication as a therapeutic tool with the morphosyntax with adolescents with Down syndrome. Methods this pilot study monitored during 12 months four adolescents chronologically aged between 13 and 15 years and mentally aged between 5 and 6 years. It were analyzed the initial and the final assessments, situations of free interaction between the participant and the caregiver videotaped during 30 minutes. The speech samples were analyzed as MLU values considering morphemes and words, comparing both the two situations. All of the participants were submitted to the same procedures during the therapeutic interventions. Picture Communication Symbols (PCS) has been used and the symbols were organized according to a simple syntactic structure (substantive + verb + complement) with a gradual extension, and the elements were rated at the following order: articles, prepositions, pronouns (personals, possessives and demonstratives), and conjunctions. Each therapeutic session was recorded in specific protocol. It was used the Wilcoxon test and the p value considered was 5%. Results spites there were no statistical significant differences, increase in number of morphemes and words used between the both assessments was observed. This improve was represented by the worked elements, including prepositions and conjunctions beyond substantives and verbs. For personal pronouns there was tendency to significance (p=0,068). Conclusion the communication system showed to be a therapeutic tool to improve the use of syntactic elements in statement structures, as articles, prepositions and conjunctions, which use for individuals with Down syndrome are difficult. .

Sons da deglutição na prática fonoaudiológica: análise crítica da literatura / Swallowing sounds in speech therapy practice: a critical analysis of the literature

Este estudo objetivou pesquisar artigos científicos internacionais publicados sobre a ausculta cervical e sua utilização na prática fonoaudiológica. Trata-se de estudo de revisão qualitativa da literatura, envolvendo os últimos 10 anos. Os artigos foram selecionados da base de dados PubMed, utilizando os descritores: auscultation cervical, deglutition e deglutition disorders. A pesquisa deveria ter sido realizada com seres humanos, adultos (maiores que 18 anos) e escrita no idioma inglês. Cada citação recuperada no banco de dados foi analisada independentemente pelos pesquisadores do estudo, visando à pertinência de sua seleção e de sua inclusão ou não no estudo. A metodologia empregada envolveu a formulação da pergunta, a localização e seleção dos estudos, e a avaliação crítica dos artigos, conforme os preceitos do Cochrane Handbook. Como resultados, foram identificados 35 estudos, dos quais 13 foram analisados, pois permitiram acesso ao texto completo e relacionavam-se diretamente ao tema. Concluiu-se que os estudos foram realizados com grupos de sujeitos saudáveis e sujeitos com diferentes tipos de patologia de base. Alguns estudos compararam os padrões encontrados nos diferentes grupos. Constatou-se que parte dos artigos buscou estudar o padrão dos sons da deglutição, com diferentes interfaces: a experiência dos avaliadores; especificidade e sensibilidade do método; e como aprimorar a técnica da ausculta cervical por meio da utilização de outros instrumentos, diferentes do estetoscópio. Com essa análise crítica, concluiu-se que utilização da ausculta cervical é importante como um instrumento utilizado juntamente de outros, na rotina da avaliação clínica da deglutição.

This study aimed to investigate international scientific papers published on the subject of cervical auscultation and its use in speech therapy. The study involved a qualitative review of the literature spanning the last 10 years. Articles were selected from the PubMed database using the following keywords: cervical auscultation, swallowing and swallowing disorders. Research was included that was conducted on adult humans (over 18 years of age) and was written in English. Each citation retrieved from the database was analyzed independently by each of the study researchers to ascertain its relevance for inclusion in the study. The methodology involved formulating the research question, locating and selecting studies and critically evaluating the articles according to the precepts of the Cochrane Handbook. As a result, 35 studies were identified; 13 articles were analyzed because they allowed access to the full text and were related directly to the subject. We found that the studies were performed with groups of healthy subjects and subjects with different types of base pathology. Some studies compared the patterns found in the different groups. Some of the research sought to study the pattern of swallowing sounds with different factors - evaluator experience, the specificity and sensitivity of the method and how to improve the technique of cervical auscultation through the use of instruments other than the stethoscope. The conclusion of this critical analysis is that cervical auscultation is an important tool to be used in conjunction with other assessment methods in the routine clinical evaluation of swallowing.

Oral motor movements and swallowing in patients with myotonic dystrophy type 1.

Oropharyngeal dysphagia and esophageal motility disorders were found to be the most important causes of aspiration pneumonia in patients with myotonic dystrophy. The purpose of this report was to evaluate clinical characteristics of the oral motor movements and swallowing of individuals with myotonic dystrophy type 1 (DM1) using a standardized clinical protocol and surface electromyography (sEMG). Participants were 40 individuals divided in two groups: G1 composed of 20 adults with DM1 and G2 composed of 20 healthy volunteers paired by age and gender to the individuals in G1. Statistical analysis included one-way ANOVA with two factors for within- and between-group comparisons and Bonferroni correction for multiple comparisons. Patients with DM1 presented deficits in posture, position, and mobility of the oral motor structures, as well as compromised mastication and deglutition. The sEMG data indicated that these patients had longer muscle activations during swallowing events. The longer duration of sEMG in the group of patients with DM1 is possibly related to myotonia and/or incoordination of the muscles involved in the swallowing process or could reflect a physiological adaptation for safe swallowing.

Swallowing sounds in speech therapy practice: a critical analysis of the literature.

This study aimed to investigate international scientific papers published on the subject of cervical auscultation and its use in speech therapy. The study involved a qualitative review of the literature spanning the last 10 years. Articles were selected from the PubMed database using the following keywords: cervical auscultation, swallowing and swallowing disorders. Research was included that was conducted on adult humans (over 18 years of age) and was written in English. Each citation retrieved from the database was analyzed independently by each of the study researchers to ascertain its relevance for inclusion in the study. The methodology involved formulating the research question, locating and selecting studies and critically evaluating the articles according to the precepts of the Cochrane Handbook. As a result, 35 studies were identified; 13 articles were analyzed because they allowed access to the full text and were related directly to the subject. We found that the studies were performed with groups of healthy subjects and subjects with different types of base pathology. Some studies compared the patterns found in the different groups. Some of the research sought to study the pattern of swallowing sounds with different factors - evaluator experience, the specificity and sensitivity of the method and how to improve the technique of cervical auscultation through the use of instruments other than the stethoscope.

The use of nouns and verbs by children with Down syndrome in two different situations.

PURPOSE: To verify the use of nouns and verbs by children with Down syndrome and to compare this use between conditions of interaction with the mother and the Speech-language pathologist (SLP). METHODS: Participants were 21 children aged between 5 and 11 years, divided into three groups, according to chronological and mental age as established by the results of the Primary Tests of Nonverbal Intelligence. The speech sample was obtained through free interaction situations that were videotaped during session of 30 minutes and transcribed in specific protocols. The first 100 utterances from the first five minutes were used. The interval between each situation ranged from 7 to 15 days. T-test and analysis of variance were used for statistical analysis and the significance level adopted was of 5%. RESULTS: More verbs than nouns were used in both conditions; however, a higher number of nouns were observed during the interaction with the SLP. The between-group comparison in the interaction with the SLP shows significant differences for verbs and nouns, but during the interaction with the mother, there was tendency for difference only for the verbs. CONCLUSION: The data indicate the growing development on using of nouns and verbs according to the increase of age. There was a higher use of verbs when compared with nouns mainly in the condition of interaction with the SLP.

Utilização de substantivos e verbos por crianças com síndrome de Down em duas situações diferentes / The use of nouns and verbs by children with Down syndrome in two different situations

OBJETIVO: Verificar a utilização de substantivos e verbos por crianças com síndrome de Down e comparar esse uso em situações de interação com o terapeuta e com a mãe. MÉTODOS: Participaram 21 crianças com idades entre 5 e 11 anos, divididas em 3 grupos igualitários com base nas idades cronológica e mental, a partir da aplicação do Primary Test of Nonverbal Intelligence. A coleta de fala foi feita a partir de situações de interação livre, gravadas em vídeo por período de 30 minutos e transcritas em protocolo específico, sendo utilizados os primeiros 100 enunciados, a partir dos 5 minutos iniciais. O tempo de intervalo entre cada situação foi de 7 a 15 dias. A análise estatística utilizou o teste-t pareado e a análise de variância (ANOVA). Foi adotado o valor de significância de 5%. RESULTADOS: Foram produzidos mais verbos do que substantivos nas duas situações de interação, sendo mais verbos e substantivos com o terapeuta do que com a mãe. A comparação entre os grupos na interação com o terapeuta mostrou diferença tanto para substantivos quanto para verbos e, com a mãe, apenas tendência à diferença para os verbos. CONCLUSÃO: Os dados apontam para crescente desenvolvimento no uso de substantivos e de verbos de acordo com o aumento da idade. Houve maior utilização de verbos que de substantivos, principalmente na situação de interação com o terapeuta.

Alimentos na consistência líquida e deglutição: uma revisão crítica da literatura / Food in liquid consistency and deglutition: a critical review of the literature

O objetivo da presente revisão de literatura foi analisar artigos científicos internacionais publicados sobre a fisiologia da deglutição de alimentos líquidos nas fases oral e faríngea. A metodologia empregada envolveu a formulação da pergunta; localização e seleção dos estudos; avaliação crítica dos artigos; conforme os preceitos do Cochrane Handbook. Foram identificados 185 artigos, dos quais se excluiu 141 por não relacionarem-se diretamente ao tema e analisou-se 29 estudos. As pesquisas estão fortemente relacionadas às formas de identificação de disfagia e não as características proporcionadas pela deglutição de diferentes consistências. Quanto à metodologia empregada nos artigos analisados observa-se que na maioria dos estudos não há grupo-controle. Os grupos estudados são heterogêneos, principalmente quando considerando indivíduos com alterações neurológicas, além disso, não há pareamento de idade na maioria dos estudos. Dessa forma, os achados desta revisão demonstram que há dificuldade na aplicabilidade clínica dos achados científicos, dificultando a prática baseada evidências.

The purpose of the present literature review was to analyze international scientific papers published on the physiology of swallowing fluids in the oral and pharyngeal phases. The employed methodology involved the formulation of the question, location and selection of studies, critical assessment of the manuscripts, according to the concepts of the Cochrane Handbook. We identified 185 articles, out of which 141 were excluded for not being directly related to the theme. Twenty-nine studies were analyzed. The researchers are strongly related to ways of identifying dysphagia and not the features offered by swallowing various consistencies. Regarding the methodology employed in the reviewed articles it is observed that in most studies there are no control groups. The studied groups are heterogeneous, especially when considering individuals with neurological disorders. In addition, subjects are not paired by age. Thus, the findings of this review indicate that there is great difficulty for clinicians to apply in their daily practice scientific findings, which in turn makes evidence-based practice very limited.
