Post-COVID-19 syndrome: An investigation of speech-language-hearing symptoms / Síndrome Pós-COVID-19: investigação de sintomas fonoaudiológicos

ABSTRACT Purpose: to investigate speech-language-hearing symptoms in adults after the acute phase of COVID-19 and the impact of these persistent symptoms on their physical and emotional aspects, functional capacity, and social relationships. Methods: 204 adults who tested positive for COVID-19 between January 2021 and July 2022 and who completed an online questionnaire, addressing different variables. Data were analyzed with descriptive statistics. Results: the most prevalent symptoms up to 30 days after infection were tiredness (46%), memory loss (40.2%), and ageusia (26.5%). The most found long-term symptoms were memory loss (34.3%), tiredness (21.1%), and difficulties in starting a sentence or conversation (10.1%). Anosmia and ageusia were also cited. These persistent symptoms had an impact on their emotional aspect (33.3%), followed by the physical (26%) and occupational (25%) ones. Conclusion: this study found persistent symptoms after the acute phase of COVID-19, which can lead to speech-language-hearing disorders, such as impaired oral language and eating. These persistent symptoms impacted the participants' emotional, physical, and occupational aspects.

A manutenção desses sintomas impactou nos aspectos emocionais, físicos e ocupacionais dos participantes.

Oral motor function in obesity.

BACKGROUND: Obese individuals may have impaired oral sensory functioning and abnormal oral motor function, a consequence of fat deposition in muscles. OBJECTIVE: To evaluate the oral motor function in obese individuals. MATERIAL AND METHODS: Three observational cross-sectional studies were performed. In total, 140 participants were evaluated: (1) orofacial myofunctional evaluation (OMES) was performed in 26 obese and 26 control subjects; (2) time taken for suction of 50 ml of water through straws of 3 mm and 6 mm of diameter was measured in 30 obese and 30 control subjects; (3) the oral phase of swallowing of 5 ml moderately thick and 5 ml extremely thick boluses was analysed by videofluoroscopy in 14 obese and 14 control subjects. Obese and non-obese control subjects had body mass index ≥40 kg/m2 and <30 kg/m2 , respectively. RESULTS: Obese subjects had worse oral myofunctional evaluation scores in posture/appearance (lips, jaw, cheeks, tongue and hard palate), in mobility (lips, tongue, jaw and cheeks) and in breathing, deglutition and mastication functions (p ≤ .020). The OMES total score was 73.5 ± 5.5 in obese and 92.8 ± 3.7 in controls subjects (p < .001). There was no difference between the groups in the time taken for 50 ml of water suction through the 3-mm- or 6-mm-diameter straw. Videofluoroscopic evaluation of the bolus swallowed demonstrated a longer oral preparation time in obese individuals for both boluses (p ≤ .040) and no difference in oral transit time (p ≥ .140). CONCLUSION: A moderate change in oral motor function was observed in obese individuals with BMI ≥40 kg/m2 .

Consciência fonológica: diferentes formas de avaliação em crianças com desenvolvimento típico / Phonological awareness: Different ways of evaluation in children with typical development

O objetivo foi verificar o desempenho em habilidades de consciência fonológica com a aplicação do teste CONFIAS in vivo e por meio de gravação em vídeo. Participaram do estudo 16 crianças com idades entre 7 e 8 anos (média de 7,8 anos), cursando o 2º e 3º ano do Ensino Fundamental e que apresentaram bom rendimento escolar. As avaliações constaram da aplicação do teste CONFIAS in vivo (P1) segundo as instruções contidas no manual do teste; e na aplicação do teste CONFIAS por meio de um vídeo (P2). Analisou-se o desempenho das crianças em cada contexto separadamente e foi feita comparação entre os dois contextos. Para a análise estatística, utilizou-se o teste de Wilcoxon e o teste de Mann-Whitney. Não houve diferença significativa entre o sexo, a idade e o tipo de procedimento usado para a aplicação do teste, mas a pontuação no nível silábico, fonêmico e total foi superior em ambos os sexos com o P2. As crianças mais velhas apresentaram melhor desempenho no teste tanto no nível silábico quanto no fonêmico, independentemente do procedimento. Constatou-se diferença estatística no desempenho dos participantes no nível silábico (p=0,02), no fonêmico (p<0,01) e na pontuação total do teste (p<0,01) quando foram comparados os procedimentos (P1 e P2) de avaliação, sendo que a maior diferença entre os contextos ocorreu no nível fonêmico (com média das diferenças de 4,1 pontos). As crianças apresentaram melhor desempenho no CONFIAS no P2 nos níveis silábico e fonêmico.

The purpose was to verify the performance in phonological awareness skills with the application of the CONFIAS test in vivo and through video recording. Sixteen children between the ages of 7 and 8 years (mean of 7.8 years) participated in the study, attending the 2nd and 3rd year of elementary school and presenting good academic performance. The evaluations consisted of the application of the CONFIAS in vivo test (P1) according to the instructions contained in the test manual; and in the application of the CONFIAS test by means of a video (P2). The performance of the children in each context was analyzed separately and a comparison was made between the two contexts. Statistical analysis was performed using the Wilcoxon test and the Mann-Whitney test. There was no significant difference between the sex, age and type of procedure used for the test application, but the syllabic, phonemic and total level scores were higher in both sexes with P2. The older children presented better performance in the test at both the syllabic and the phonemic level, regardless of the procedure. Statistical differences were found in the syllabic performance (p=0.02), phonemics (p<0.01) and total test score (p<0.01) when the procedures (P1 and P2). The greatest difference between the contexts occurred at the phonemic level (with a mean difference of 4.1 points). The children presented better performance in the CONFIAS in P2, in the syllabic and phonemic levels.

Treatment indicators influence speech therapy discharge time.

PURPOSE: To compare the treatment time for acquired neurological disorders of communication and the reason for discharge of users of a medium complexity care service for two periods: before and after implementation of treatment indicators. METHODS: A retrospective cohort study was carried out involving the analysis of medical records of users of the Adult Language Sector of the Speech and Hearing Therapy Service of the Integrated Rehabilitation Center, seen before and after treatment indicators implementation. RESULTS: 129 electronic medical records of users who remained under treatment until discharge from speech therapy in the two studied periods were analyzed. The mean duration of speech therapy for these users was 10.9 months for the first period and 7.8 months for the second period. After implementation of the indicators with regular reassessments, 72 out of the 89 users continued with treatment. There was a statistically significant difference in the therapy average time and reason for discharge before and after treatment indicators implementation. CONCLUSION: After treatment indicators implementation, there was a reduction of the average speech therapy treatment time for communication disorders and an increase of speech therapy discharge percentage of users seen in a Brazilian service of medium complexity.

Intervenção fonoaudiológica na deficiência visual associada à paralisia cerebral: relato de um caso / Speech-language intervention in a visually impaired patient associated with cerebral palsy: a case report

Introdução: O atraso neuropsicomotor acarreta em prejuízos no processo de aquisição e desenvolvimento de habilidades gerais, dentre elas, a linguagem, e, pode estar associado com outros déficits, como a paralisia cerebral e a deficiência visual. Objetivo: Descrever a intervenção fonoaudiológica em um caso de uma deficiente visual com paralisia cerebral. Relato de caso: Criança de 2,5 anos, sexo feminino, com diagnóstico de distúrbio de linguagem associado a cegueira no olho direito e visão subnormal no olho esquerdo, causados por retinopatia da prematuridade e catarata congênita, em associação com encefalopatia (paralisia cerebral espástica diparética). Após o processo de avaliação fonoaudiológica, foi iniciada a intervenção em linguagem baseada no modelo sócio construtivista com foco na interação, expressão e compreensão da linguagem oral. Durante o processo de avaliação e reabilitação fonoaudiológica foram adaptados objetos concretos (reais), com textura diferenciada ao toque, e associados a sons verbais e não verbais, como recurso para a eliciação de resposta comunicativa. Após 14 sessões de terapia observou-se evolução do comportamento linguístico, com produção oral de palavras isoladas e frases simples com participação ativa na atividade dialógica e compreensão de ordens semicomplexas. Conclusão: Em pacientes com deficiência visual associada a paralisia cerebral, o uso e adaptação de pistas táteis e olfativas auxiliam na percepção e reconhecimento dos objetos, facilitando a intervenção fonoaudiológica.

Introduction:Neuropsychomotor developmental delay leads to losses in the acquisition and development of general abilities, among them language. It may be associated with other deficits, such as cerebral palsy and visual impairment. Objective: Describe the speech-language intervention in a case of a visually impaired person with cerebral palsy. Case report: A 2.5-year-old female was diagnosed with a language disorder associated with blindness in the right eye and subnormal vision in the left eye. The cause was retinopathy of prematurity and congenital cataract in association with encephalopathy (spastic cerebral palsy diphtheric). After speech-language evaluation process, intervention was started based on the socio-constructivist model, which focuses on the interaction, expression, and comprehension of oral language. During the process of evaluation and speech-language rehabilitation, concrete (real) objects with a texture that was differentiated to the touch and associated with verbal and non-verbal sounds were adapted as a resource for the elicitation of communicative response. We observed after 14 sessions of therapy, the evolution of linguistic behavior involving oral production of isolated words and simple sentences with effective participation in the dialogical activity and understanding of semi-complex orders. Conclusion: In patients with visual impairment associated with cerebral palsy, the use and adaptation of tactile and olfactory cues help in the perception and recognition of the objects, which facilitates the speech-language intervention.

Dinâmica da ingestão de água em pacientes com acalasia: influência de sexo e idade / Water ingestion dynamics in patients with achalasia: influence of sex and age

ABSTRACT BACKGROUND: Achalasia is a disease that affects esophageal bolus transit due to the absence of esophageal peristaltic contractions and impaired or absent relaxation of the lower esophageal sphincter. OBJECTIVE: The objective of this investigation was: a) to evaluate the dynamics of water ingestion in patients with achalasia, idiopathic or caused by Chagas' disease; b) to evaluate the influence of sex and age on water ingestion dynamics. METHODS: The investigation was conducted with 79 patients with achalasia (27 idiopathic and 52 Chagas' disease) and 91 healthy volunteers, all evaluated by the water-drinking test. The individuals drank, in triplicate, 50 mL of water without interruption. The time and the number of swallows for this task were counted. We also measured: (a) inter-swallow interval - the time to complete the task, divided by the number of swallows during the task; (b) swallowing rate - volume drunk divided by the time; (c) volume per swallow - volume drunk divided by the number of swallows. RESULTS: Patients with achalasia took longer to ingest all the volume (mean 12.2 seconds) than healthy controls (mean 5.4 seconds), had greater number of swallows, longer interval between swallows, lower swallowing rate (5.2 mL/s vs 10.9 mL/s in controls) and lower volume per swallow (9.1 mL vs 14.4 mL in controls, P<0.01). Among healthy volunteers, women had a shorter interval between swallows and lower volume per swallow compared with men, and in the achalasia group, women had a longer interval between swallows and lower ingestion rate. No difference in the drinking test results was found between younger and older subjects in achalasia or control group. Also, no differences were observed between patients with Chagas' disease and those with idiopathic achalasia, or between patients with increased and normal esophageal diameter. CONCLUSION: Patients with achalasia have difficulty in ingesting water, taking a longer time to complete the task, which is influenced by sex but not by age or severity of the disease.

RESUMO CONTEXTO: Acalásia é uma doença que causa dificuldade no transporte do bolo deglutido da boca ao estômago, consequente à ausência das contrações peristálticas no esôfago e relaxamento parcial ou ausente do esfíncter inferior do esôfago. OBJETIVO: O objetivo desta investigação foi: a) avaliar a dinâmica da ingestão de água em pacientes com acalásia, idiopática ou causada pela doença de Chagas; b) avaliar a influência do sexo e da idade na dinâmica da ingestão de água. MÉTODOS: A investigação foi realizada em 79 pacientes com acalásia (27 idiopática e 52 Chagas) e 91 voluntários saudáveis, todos avaliados pelo teste de ingestão de água. Os indivíduos ingeriam, em triplicata e sem pausas, 50 mL de água, a ingestão era cronometrada e o número de deglutições contadas. Também foram medidos: (a) intervalo entre deglutições - tempo para completar a tarefa, dividido pelo número de deglutições durante a tarefa; (b) fluxo de deglutição - volume ingerido dividido pelo tempo de ingestão; (c) volume de cada deglutição - volume ingerido dividido pelo número de deglutições. RESULTADOS: Os pacientes com acalásia levaram mais tempo (média 12,2 segundos) para ingerir todo o volume que voluntários sadios (5,4 segundos), e apresentaram maior número de deglutições, intervalo mais longo entre as deglutições, menor fluxo de deglutição (5,2 mL/s vs 10,9 mL/s, nos controles) e menor volume em cada deglutição (9,1 mL vs 14,4 mL nos controles). Entre os voluntários saudáveis, as mulheres tiveram um intervalo entre deglutições mais curto e menor volume em cada deglutição em comparação aos homens e, na acalásia, as mulheres tiveram um intervalo mais longo entre as deglutições e menor fluxo de ingestão. Não houve diferenças significativas entre indivíduos mais jovens e mais velhos, entre os voluntários saudáveis e entre os indivíduos com acalásia. Não houve diferenças entre pacientes com doença de Chagas e pacientes com acalasia idiopática, ou entre pacientes com aumento ou não no diâmetro esofágico. CONCLUSÃO: Pacientes com acalásia têm dificuldade em ingerir água, levando mais tempo para completar a tarefa, que é influenciada pelo sexo dos indivíduos, mas não pela idade ou dilatação do esôfago.

Videofluoroscopic evaluation of swallows in anorexia nervosa / Avaliação videofluoroscopica da deglutição na anorexia nervosa

ABSTRACT Background There are some studies in the literature about the feeding behavior and masticatory process in patients with feeding disorders; however, it is not very well known if there are alterations in oral-pharyngeal swallowing dynamics in subjects with anorexia nervosa. Objective To evaluate the oral and pharyngeal bolus transit in patients with anorexia nervosa. Methods The study was conducted with 8 individuals clinically diagnosed and in treatment for restricting-type anorexia nervosa (seven women and one man), and 14 healthy individuals with no digestive or neurological symptoms (10 women, 4 men). Swallows were evaluated by videofluoroscopy with three swallows of 5 mL liquid bolus and three swallows of 5 mL paste bolus consistency, given in a random sequence. The participants were asked after each swallow about the sensation of the bolus passage. Results In the analysis of oral-pharyngeal transit duration, the mean duration of pharyngeal transit with paste bolus in patients with anorexia was shorter than in healthy volunteers (P=0.02). In the duration of movement of the hyoid bone, longer movement was observed in anorexia than in healthy volunteers with liquid bolus (P=0.01). With liquid bolus, five (62.5%) patients and one (7.1%) control had sensation of the bolus passage (P<0.05). Conclusion There seems to be no important alterations of swallowing in subjects with anorexia nervosa, although the results suggest that pharyngeal transit has shorter duration than that seen in healthy volunteers and the hyoid movement duration is longer in patients than in healthy volunteers. Fast pharyngeal transit may be the cause of bolus transit perception in patients with anorexia nervosa.

RESUMO Contexto Existem alguns estudos na literatura sobre o comportamento alimentar e da mastigação em pacientes com distúrbios da alimentação, no entanto não é conhecido se há alterações na dinâmica da deglutição em indivíduos com anorexia nervosa. Objetivo Avaliar o trânsito oral e faríngeo em pacientes com anorexia nervosa. Métodos O estudo foi realizado em 8 indivíduos com diagnóstico e em tratamento para anorexia nervosa do tipo restritivo (sete mulheres e um homem), e 14 indivíduos saudáveis, sem sintomas digestivos ou neurológicos (10 mulheres e 4 homens). Os trânsitos oral e faríngeo foram avaliados por videofluoroscopia, com três deglutições de 5 mL de bolo líquido e três deglutições de 5 mL de bolo na consistência pastosa, ingeridos em sequência aleatória. Os participantes foram arguidos, após cada deglutição, sobre a sensação da passagem do bolo. Resultados A duração do trânsito faríngeo com o bolo pastoso, em pacientes com anorexia, foi mais curta do que em voluntários saudáveis (P=0,02). Com bolo líquido a duração do movimento do osso hióide foi mais longa na anorexia do que em voluntários saudáveis (P=0,01). Com bolo líquido, cinco (62,5%) pacientes e um controle (7,1%) tiveram sensação da passagem de bolus (P<0,05). Conclusão Não parece haver importantes alterações da deglutição em pacientes com anorexia nervosa, embora os resultados indiquem que o trânsito faríngeo tem duração mais curta do que a observada em voluntários saudáveis e a duração do movimento do hióide é maior em pacientes do que em voluntários saudáveis. O trânsito faríngeo rápido pode ser a causa da percepção da passagem do bolo em pacientes com anorexia nervosa.

POSTFUNDOPLICATION DYSPHAGIA CAUSES SIMILAR WATER INGESTION DYNAMICS AS ACHALASIA.

BACKGROUND: - After surgical treatment of gastroesophageal reflux disease dysphagia is a symptom in the majority of patients, with decrease in intensity over time. However, some patients may have persistent dysphagia. OBJECTIVE: - The objective of this investigation was to evaluate the dynamics of water ingestion in patients with postfundoplication dysphagia compared with patients with dysphagia caused by achalasia, idiopathic or consequent to Chagas' disease, and controls. METHODS: - Thirty-three patients with postfundoplication dysphagia, assessed more than one year after surgery, together with 50 patients with Chagas' disease, 27 patients with idiopathic achalasia and 88 controls were all evaluated by the water swallow test. They drunk, in triplicate, 50 mL of water without breaks while being precisely timed and the number of swallows counted. Also measured was: (a) inter-swallows interval - the time to complete the task, divided by the number of swallows during the task; (b) swallowing flow - volume drunk divided by the time taken; (c) volume of each swallow - volume drunk divided by the number of swallows. RESULTS: - Patients with postfundoplication dysphagia, Chagas' disease and idiopathic achalasia took longer to ingest all the volume, had an increased number of swallows, an increase in interval between swallows, a decrease in swallowing flow and a decrease in water volume of each swallow compared with the controls. There was no difference between the three groups of patients. There was no correlation between postfundoplication time and the results. CONCLUSION: - It was concluded that patients with postfundoplication dysphagia have similar water ingestion dynamics as patients with achalasia.

RESUMO Contexto - Após o tratamento cirúrgico da doença do refluxo gastroesofágico, disfagia é um sintoma presente na maioria dos pacientes, com diminuição de intensidade ao longo do tempo. No entanto, alguns pacientes podem ter disfagia persistente. Objetivo - O objetivo deste trabalho foi avaliar a dinâmica da ingestão de água em pacientes com disfagia persistente após tratamento cirúrgico da doença do refluxo gastroesofágico comparando-os com os pacientes com disfagia causada por acalásia, idiopática ou consequente à doença de Chagas, e controles. Métodos - Trinta e três pacientes com disfagia pós fundoplicatura, que persiste a mais de um ano após a cirurgia, em conjunto com 50 pacientes com doença de Chagas, 27 pacientes com acalásia idiopática, todos com disfagia, e 88 controles foram avaliados pelo teste de ingestão de água. Eles ingeriram, em triplicata e sem pausas, 50 mL de água, o tempo de ingestão foi precisamente cronometrado e contado o número de deglutições necessário para ingerir todo volume. Com estes resultados foram calculados: (a) intervalo entre deglutições - tempo para completar a ingestão dividido pelo número de deglutições; (b) fluxo de ingestão - volume ingerido dividido pelo tempo necessário; (c) volume em cada deglutição - volume ingerido dividido pelo número de deglutições. Resultados - Os pacientes com disfagia pós fundoplicatura, doença de Chagas e acalásia idiopática levaram mais tempo para ingerir todo volume, tiveram maior número de deglutições, maior intervalo entre as deglutições, diminuição do fluxo de ingestão e diminuição no volume de água de cada deglutição em comparação com os controles. Não houve diferença entre os três grupos de pacientes. Não houve correlação entre o tempo após a operação e os resultados. Conclusão - Os pacientes com disfagia pós fundoplicatura tem dinâmica de ingestão de água semelhante aos pacientes com acalasia.

Influence of age on swallows of a highly viscous liquid bolus.

BACKGROUND: Swallow function has a decline with aging, mainly in those over 80 years old. In the population over 69 years, about 11% of subjects reported symptoms indicative of significant dysphagia. OBJECTIVES: Our objective was to evaluate the hypothesis that older asymptomatic subjects before 80 years old have compensations to sustain a safe and efficient swallow, at least with swallows of liquid bolus. METHODS: We performed videofluoroscopic evaluation of swallows in 55 normal volunteers, a younger group with 33 subjects (16 men and 17 women) aged 19 to 55 years, mean 35.5±9.8 years, and an older group with 22 subjects (15 men and 7 women) aged 56 to 77 years, mean 64.8±6.8 years. The subjects swallowed in duplicate 5 mL and 10 mL of liquid barium with a pH of 7.9, density of 1.82 g/cm3, and viscosity of 895 cp. Results The mean duration of pharyngeal transit, pharyngeal clearance, upper esophageal sphincter opening, hyoid movement and oral-pharyngeal transit were longer in the younger group compared with the older group. The relation between pharyngeal clearance duration and hyoid movement duration was similar in younger and older subjects, for 5 mL and 10 mL bolus volumes. CONCLUSIONS: On average, a highly viscous liquid bolus crosses the pharynx faster in older subjects (56-77 years old) than in younger subjects (19-55 years old), which suggested an adaptation to the aging process to maintain a safe swallow.

Oral and pharyngeal bolus transit in patients with chronic obstructive pulmonary disease.

BACKGROUND: Patients with respiratory diseases, such as chronic obstructive pulmonary disease (COPD), may have swallowing dysfunction. OBJECTIVE: The aim of this investigation was to evaluate the oral and pharyngeal phases of swallowing in patients with COPD. METHODS: We studied 16 patients with clinical manifestations and pulmonary function tests diagnosis of COPD (mean age: 68 years) and 15 nonsmoking healthy volunteers (mean age: 65 years) with normal pulmonary function tests. All subjects were submitted to clinical and videofluoroscopic evaluation of swallowing. Each subject performed in duplicate swallows of 5 mL and 10 mL of liquid bolus, paste bolus, and a solid bolus. RESULTS: In general, the duration of the events of the pharyngeal phase of swallowing was longer in COPD patients than controls. The difference was significant in the laryngeal vestibular closure, hyoid movement, and pharyngeal transit with swallows of both volumes of liquid bolus; in oral-pharyngeal transit with 5 mL paste bolus; and in pharyngeal and oral-pharyngeal transit with solid bolus. The difference between the duration of maximal laryngeal elevation and the duration of pharyngeal transit was higher in control subjects than in patients with COPD. CONCLUSION: The results suggested that patients with COPD have a longer pharyngeal swallowing phase than normal subjects, which is associated with a decrease in the difference between the duration of maximal laryngeal elevation and the duration of pharyngeal transit.

Influence of ag on swallows of a highly viscous liquid bolus / Influência da idade na deglutição de bolo líquido com alta viscosidade

Background Swallow function has a decline with aging, mainly in those over 80 years old. In the population over 69 years, about 11% of subjects reported symptoms indicative of significant dysphagia. Objectives Our objective was to evaluate the hypothesis that older asymptomatic subjects before 80 years old have compensations to sustain a safe and efficient swallow, at least with swallows of liquid bolus. Methods We performed videofluoroscopic evaluation of swallows in 55 normal volunteers, a younger group with 33 subjects (16 men and 17 women) aged 19 to 55 years, mean 35.5±9.8 years, and an older group with 22 subjects (15 men and 7 women) aged 56 to 77 years, mean 64.8±6.8 years. The subjects swallowed in duplicate 5 mL and 10 mL of liquid barium with a pH of 7.9, density of 1.82 g/cm3, and viscosity of 895 cp. Results The mean duration of pharyngeal transit, pharyngeal clearance, upper esophageal sphincter opening, hyoid movement and oral-pharyngeal transit were longer in the younger group compared with the older group. The relation between pharyngeal clearance duration and hyoid movement duration was similar in younger and older subjects, for 5 mL and 10 mL bolus volumes. Conclusions On average, a highly viscous liquid bolus crosses the pharynx faster in older subjects (56-77 years old) than in younger subjects (19-55 years old), which suggested an adaptation to the aging process to maintain a safe swallow. .

Contexto A função de deglutição tem um declínio com o envelhecimento, principalmente em pessoas com mais de 80 anos de idade. Na população com mais de 69 anos cerca de 11% dos indivíduos relatam sintomas indicativos de disfagia. Objetivos O nosso objetivo foi avaliar a hipótese de que o indivíduo assintomático antes dos 80 anos de idade tem compensações que mantém deglutição segura e eficiente, pelo menos com deglutição de líquido. Métodos Foi realizada avaliação videofluoroscópica da deglutição em 55 voluntários normais, um grupo mais jovem, com 33 indivíduos (16 homens e 17 mulheres) com idades entre 19-55 anos, média de 35,5 ± 9,8 anos e um grupo mais velho, com 22 indivíduos (15 homens e 7 mulheres) com idades entre 56-77 anos, média de 64,8 ± 6,8 anos. Os indivíduos ingeriram, em duplicata, 5 mL e 10 mL de sulfato de bário líquido, com pH de 7,9, densidade de 1,82 g/cm3, e viscosidade de 895 cp. Resultados A duração média do trânsito faríngeo, da depuração da faringe, da abertura do esfíncter superior do esôfago, do movimento do osso hióide e do trânsito oro-faríngeo foi mais longa no grupo mais jovem em comparação com o grupo mais velho. A relação entre a duração da depuração da faringe e duração do movimento do osso hióide foi semelhante em indivíduos mais jovens e mais velhos, com os volumes de 5 mL e 10 mL. Conclusões Em média, um bolo líquido altamente viscoso atravessa a faringe mais rápido em indivíduos mais velhos (56-77 anos de idade) do que em indivíduos mais jovens (19-55 anos de idade), o que sugere uma adaptação ao processo de envelhecimento para manter uma deglutição segura. .

Timing of Pharyngeal Swallow Events in Chagas' Disease.

BACKGROUND: Esophageal involvement by Chagas' disease causes a significative decrease in the number of neurons of the esophageal myenteric plexus, causing an impairment of esophageal motility with the same alterations described in primary esophageal achalasia. There is also a longer duration of pharyngeal transit, which might be consequent of the involvement of the central control of swallowing by the disease, or an adaptation of the pharynx to the difficult bolus transit through the esophagus, which could contribute to the complaint of dysphagia. METHODS: We studied, by videofluoroscopy, the sequence and timings of pharyngeal bolus transit in 16 patients with esophageal involvement by Chagas' disease and 12 healthy volunteers. Each subject swallowed in duplicate 5 mL and 10 mL of liquid and paste boluses. RESULTS: There was no difference between Chagas' disease patients and normal volunteers in the sequence and timing of events associated with pharyngeal bolus flow, for liquid and paste boluses, and for 5 mL and 10 mL. CONCLUSION: The timing and sequence of swallow pharyngeal events of patients with Chagas' disease do not differ from that of control subjects, which suggested that the central control of swallowing is not impaired by the disease.

Pharyngeal transit adaptation to bolus volume and consistency in Chagas' disease / Adaptação do trânsito faríngeo ao volume e consistência do bolo deglutido na doença de Chagas

Background: Esophageal Chagas' disease causes a longer pharyngeal bolus clearance, which may be an adaptation to the impairment of esophageal bolus transit. This adaptation should be present when we change volume or consistency of the swallowed bolus. Methods: By the videofluoroscopic method, the correlation was calculated between bolus volumes of 5 and 10mL, and consistencies liquid and paste on pharyngeal clearance duration and hyoid movement duration using the Pearson correlation coefficient (r). It was evaluated 17 patients with Chagas' disease and 15 normal volunteers. Results: In both groups, there was no correlation between the pharyngeal clearance duration and the hyoid movement duration. In pharyngeal clearance there was a positive correlation between the volumes of 5 and 10mL and between liquid and paste boluses in patients with Chagas' disease, but not in controls. In hyoid movement duration the correlation between the volumes of 5 and 10mL was positive and significant in Chagas' disease patients for liquid and paste bolus, and only for paste in controls. Conclusion: Patients with Chagas' disease have a positive correlation of bolus flow through the pharynx related to change in bolus volume and bolus consistency, which suggested that they have a more important control of pharyngeal flow related to bolus volume and consistency than normal volunteers...

Justificativa: Envolvimento do esôfago pela doença de Chagas provoca aumento na duração da depuração da faringe, o que pode ser uma adaptação consequente ao comprometimento do trânsito do bolo pelo esôfago. Esta adaptação deve estar presente quando variamos o volume e consistência do bolo deglutido. Métodos: Foi realizada, com o método videofluoroscópico, avaliação da duração da depuração faríngea e da duração do movimento do osso hióide com a deglutição de bolos de 5 e 10mL, e consistências líquida e pastosa em 17 pacientes com doença de Chagas e 15 voluntários saudáveis. Foi calculada a correla­ção entre os resultados por meio do coeficiente de correlação de Pearson (r). Resultados: Em pacientes com doença de Chagas e voluntários, não houve correlação entre a duração da depuração da faringe e da duração do movimento do hióide. Em pacientes com doença de Chagas, na depuração da faringe, houve correlação positiva entre os volumes de 5 e 10mL e entre bolos líquido e pastoso, o que não foi observado nos voluntários. Na duração do movimento do hióide a correlação entre os volumes de 5 e 10mL foi positiva e significativa em pacientes com doença de Chagas para bolo líquido e pastoso, e apenas para pastoso nos voluntários. Conclusão: Pacientes com doença de Chagas têm correlação positiva do fluxo pela faringe relacionada com a alteração no volume e consistência do bolo, o que sugere um maior controle do fluxo pela faringe do que o observado em voluntários normais...

Diferenças entre homens e mulheres da mesma altura corporal no teste de ingestão de água / Differences between men and women with the same height in the water swallow test

Introdução: há trabalhos que demonstram que a dinâmica da deglutição é influenciada pelo gênero, o que poderia ser consequente a diferenças anatômicas entre homens e mulheres. Entretanto, estes trabalhos não consideraram o possível efeito da altura corporal dos indivíduos. Nossa hipótese é que as diferenças previamente observadas não devem acontecer quando os indivíduos tiverem idades e alturas semelhantes. Objetivo: avaliar a dinâmica da deglutição de água em homens e mulheres com idades e alturas corporais semelhantes. Método: utilizando o teste de ingestão de água, estudamos 60 voluntários saudáveis, 30 homens [idade: 40,7 (12,9) anos, altura: 1,69 (0,05)m] e 30 mulheres [idade: 37,3 (11,4) anos, altura: 1,68 (0.05)m]. O teste foi realizado com o voluntário sentado, com a ingestão contínua de 50 ml de água, e a medida do tempo de ingestão e contagem do número de deglutições para ingerir todo volume. Com estes resultados, calculamos o intervalo entre deglutições, o fluxo de ingestão e o volume por deglutição. Resultados: o número de deglutições para ingerir todo volume foi, em média, maior nas mulheres [4,3 (1,6)] do que nos homens [3,9 (1,8); p=0,04]. Sendo assim, o volume por deglutição foi menor nas mulheres [13,4 (5,0) ml] do que o volume por deglutição observado nos homens [17,3 (12,5) ml; p=0,04]. Não houve diferença entre os gêneros no tempo de ingestão, no intervalo entre deglutições e no fluxo de ingestão. Conclusão: mulheres ingerem água em menor volume em cada deglutição quando comparadas com homens com idades e alturas corporais semelhantes.

Introduction: there are results reporting that there are differences between men and women in the dynamics of swallowing, which may be consequence of anatomic differences between genders. Objective: to evaluate the dynamics of water ingestion in men and women with similar heights and ages. Our hypothesis was that the differences previously found might not be seen if they have similar age and similar height. Method: we evaluated by the water swallow test the dynamics of water ingestion in 60 healthy volunteers, 30 men [age: 40.7 (12.9) years; height: 1.69 (0.05)m] and 30 women (age: 37.3 (11.4) years; height: 1.68 (0.05) m]. The test was performed with the volunteers in the sitting position. They ingested continuously and confortably 50 ml of water while precisely timed and counted the number of swallows needed to ingest all the volume. Results: The number of swallows to ingest all the volume was greater in women [4.3 (1.6)] than in men [3.9 (1.8); p=0.04]. The volume capacity in each swallow was smaller in women [13.4 (5.0) ml] than in men [17.3 (12.5) ml; p=0.04]. There was no difference in the duration of ingestion, in the time between swallows and in the flux of ingestion. Conclusion: even with similar ages and height women ingest water in smaller volume in each swallow than men.

Variability of Oral and Pharyngeal Transit Between Two Consecutive Swallows in Chagas' Disease.

BACKGROUND: Chagas' disease causes dysphagia, regurgitation and retention of food in the esophageal body. Patients have longer pharyngeal clearance, which might be consequent of the involvement of the central nervous system or an adaptation to the esophageal transit impairment. If there is central nervous system involvement by the disease, we expect a larger difference in the oral and pharyngeal phases of swallowing between two consecutive swallows than that seen in controls. Our objective was to evaluate the difference of oral and pharyngeal transit duration between two consecutive swallows in patients with Chagas' disease compared with controls. METHODS: By videofluoroscopy, the duration of oral and pharyngeal transit, pharyngeal clearance, upper esophageal sphincter transit, hyoid movement and oropharyngeal transit was measured in 17 patients with Chagas' disease and 15 asymptomatic volunteers. Each subject swallowed in duplicate and in sequence 5 mL and 10 mL of barium liquid and 5 mL and 10 mL of barium paste boluses. The differences were calculated between the two swallows of each volume and consistency in patients and controls. RESULTS: There were no differences between controls and patients in the values of the differences between the two consecutive swallows, except for the hyoid movement duration of the 5 mL liquid bolus, causing a higher difference in controls than in patients. CONCLUSION: Oral and pharyngeal transit variation between two consecutive swallows is similar between patients with Chagas' disease and controls, which suggests that the longer pharyngeal clearance duration previously described is not a consequence of impairment of the central nervous system control of swallowing.

Competência glótica na doença pulmonar obstrutiva crônica / Glottal competence in chronic obstructive pulmonary disease

OBJETIVO: Correlacionar a medida do tempo máximo de fonação (TMF) com o volume de ar pulmonar expirado no primeiro segundo do sopro (VEF1) e comparar o TMF, emissão do "s", "z" e relação s/z em indivíduos saudáveis e indivíduos com doença pulmonar obstrutiva crônica (DPOC). MÉTODOS: Foram avaliados 14 voluntários saudáveis, com média de idade de 65 anos, e 16 indivíduos com DPOC, com média de idade de 68 anos. O diagnóstico da doença foi clínico e também obtido por exames da função pulmonar. Os participantes foram submetidos à espirometria para apreciação dos parâmetros VEF1, capacidade vital forçada (CVF) e o índice de Tiffeneau (VEF1/CVF). Registrou-se a emissão prolongada das vogais "a", "i", "u" para análise do tempo máximo de fonação na condição normal e forçada e aferiu-se a relação s/z após a sustentação dos fonemas /s/ e /z/. RESULTADOS: Nos dois grupos, o TMF com a fonação normal foi menor do que o tempo máximo de fonação, com a fonação forçada. A mediana do TMF do grupo controle foi maior do que a do grupo com DPOC, com a fonação normal e a fonação forçada. Não houve correlação entre o tempo máximo de fonação e os valores de VEF1 nos grupos. CONCLUSÃO: Pacientes com DPOC tem diminuição do tempo máximo de fonação e a relação s/z sugere falta de coaptação glótica. Não houve correlação do TMF e a medida do VEF1.

PURPOSE: This study correlates the extent of maximum phonation time (MPT) with the volume of air exhaled in the first second pulmonary (FEV1) and compares the MPT emission of /s/, /z/ and s/z ratio in healthy subjects and those with chronic obstructive pulmonary disease (COPD). METHODS: We studied 14 normal volunteers (control group), mean age 65 years, and 16 patients with COPD, mean age 68 years. The diagnosis of COPD was done by clinical and pulmonary function evaluation. Participants underwent spirometry for analysis of the parameters FEV1, forced vital capacity (FVC) and Tiffeneau index (FEV1/FVC). The maximum phonation time, along with phonemes /s/ and /z/, s/z ratio correlation, and maximum phonation time in both normal and forced phonation were collected and recorded. RESULTS: In both groups, the maximum phonation time with normal phonation was lower than the maximum phonation time with forced phonation. The median of the maximum phonation time in the control group was higher than in the COPD group. There was no correlation between the maximum phonation time and FEV1, in normal volunteers and patients with COPD. CONCLUSION: Patients with COPD have decreased maximum phonation time, while the s/z ratio does not suggest changes in the level of the vocal folds, since the values found were within the normal range. There was no correlation of the TMF and the measure of FEV1.
