Swallow Impairment in Parkinson's Disease: Revelations from High-Resolution Videomanometry.

Parkinson's disease (PD) is a degenerative disorder that can cause dysphagia and dysphonia. We studied upper esophageal sphincter (UES) function and vocal tests using high-resolution videomanometry (HRVM) in PD. Ten healthy volunteers and 20 patients with PD performed swallowings (5 ml and 10 ml) and vocal tests using HRVM synchronized to the vocal acoustic recording. Mean age of the Parkinson group was 68.7 ± 9.7 years and mean disease stage of 2.7 ± 1.1 (Hoehn & Yahr scale). In videofluoroscopy swallow study (VFSS) for 5 ml, laryngeal elevation was significantly reduced (p = 0.01) in PD and for 10 ml, anteriorization (p = 0.03), elevation (p = 0.03) and total displacement (p = 0.05) were reduced in PD. In high-resolution manometry (HRM) for both volumes, intrabolus pressure was significantly higher in PD (p = 0.0004 and p = 0.001) and a higher NADIR UES relaxation pressure and NADIR UES relaxation at pharyngeal peak contraction in PD (p = 0.00007 and p = 0.0003, p = 0.01 and p = 0.04), respectively. Vocal tests results showed differences between the groups, especially for larynx anteriorization with high pitch /a/ emission (p = 0.06) in VFSS and for UES length with high pitch /i/ with tongue protrusion (p = 0.07) in HRM. Our results demonstrated a reduced compliance and subtle changes in UES function in early and moderate PD stage. We also demonstrated using HRVM that vocal tests can affect UES function. The use of HRVM proved to be an important tool in the description of events related to phonation and swallowing, which can affect the rehabilitation of patients with PD.

THE DYSPHAGIA INVESTIGATION: IS THERE STILL SPACE FOR THE VIDEOFLUOROSCOPIC METHOD?

AIM: Dysphagia can lead to aspiration pneumonia, impacting the nutritional status and quality of life of the patient. The videofluoroscopy is highlighted for allowing both a real-time evaluation and the recording of the images for later review and analysis. This study aimed to describe the characteristics of the population referred for videofluoroscopy and its value as an investigation method. METHODS: A descriptive and retrospective study was conducted. Exams were analyzed in lateral and anteroposterior views and reviewed using the frame-by-frame analysis software. The variables analyzed were an indication of the exam, previous diseases, dynamics of the oral and pharyngeal phases, and the degree of penetration/aspiration. RESULTS: A total of 141 exams were analyzed. The study population had a median age of 66.24±17.78 years. For the indication of the exam, the investigation of dysphagia was highlighted (n=87, 61.7%) and for previous conditions, diverticulum (n=13, 9.2%), pharyngeal bar (n=12, 8.51%), and stroke and Parkinson's disease (n=9, 6.4%) were highlighted. In the oral phase, 45 (31.9%) patients had a premature loss, and 108 (76.6%) patients had normal transit time. However, 100 (70.9%) had inadequate ejection. In the pharyngeal phase, 119 (84.4%) had efficient laryngeal displacement and 107 (75.9%) had an adequate opening of the upper esophageal sphincter. The beginning of the pharyngeal phase was classified as inadequate in 131 (92.9%) patients, and 80 (56.74%) had pharyngeal residue. Notably, 100 (70.9%) patients had grade 1 on the penetration/aspiration scale. CONCLUSION: Despite the didactic division of phases, swallowing is complex and has transition stages. Videofluoroscopy is the only method for evaluating all phases of swallowing and its events.

Na fase faríngea, 119 (84,4%) apresentaram deslocamento laríngeo eficiente e 107 (75,9%) abertura adequada do esfíncter esofágico superior. O início da fase faríngea foi classificado como inadequado em 131 pacientes (92,9%) e 80 (56.74%) apresentaram resíduo faríngeo. 100 pacientes (70,9%) apresentaram grau 1 na escala de penetração/aspiração CONCLUSÃO: apesar da divisão didática das fases, a deglutição é uma função complexa e possui etapas de transição. A videofluoroscopia é o único método para avaliar todas as fases da deglutição e seus eventos.

[Higher prevalence of obesity in erosive gastroesophageal reflux disease]. / Maior prevalência de obesidade na doença do refluxo gastroesofagiano erosiva.

CONTEXT: Weight loss is commonly recommended as a treatment for gastroesophageal reflux; however, a relationship between excessive body weight and gastroesophageal reflux disease is not well established. OBJECTIVES: To evaluate the prevalence of obesity and over-weight in patients with heartburn, with and without erosive esophagitis; to analyze the prevalence of hiatal hernia and the intensity of abnormal gastroesophageal reflux in both groups of patients, and its relation to body mass index. METHODS: The data of pH monitoring of 362 individuals with heartburn were evaluated retrospectively. All patients had an upper gastrointestinal endoscopy and erosive esophagitis was defined by the presence of macroscopic erosion on the esophageal mucosa. Hiatal hernia was considered when the gastroesophageal junction was positioned 2 cm or more above the diaphragm. Patients with Barrett's esophagus or esophageal peptic stenosis were excluded. The population was categorized according to body mass index as normal weight (body mass index between 20 and 24.9); over-weight (between 25 and 29.9), and obese (greater than 30). The diagnosis as well as the intensity of abnormal gastroesophageal reflux were obtained through the analysis of the results of pH monitoring in patients with and without erosive esophagitis and in the various categories of body mass index. RESULTS: Among the 362 patients there were 148 (41%) with erosive esophagitis and 214 (59%) without erosive esophagitis, while the pH monitoring was abnormal in 100% and 57%, respectively. Among the 148 individuals with erosive esophagitis (61% male, median age 50 years), 41 (28%) had normal weight, 82 (55%) had over-weight and 25 (17%) were obese. There were 88 (60%) patients with hiatal hernia, which was present in 29 (71% of patients with normal weight), 45 (55% of patients with over-weight) and 14 (56% of obese individuals). In 121 patients without erosive esophagitis who had abnormal pH monitoring, diagnosed as non erosive reflux disease (38% male, median age 50 years), 51 (42%) patients had normal weight, 55 (46%) had over-weight and 15 (12%) were obese. Hiatal hernia was detected in 52 out of 121 (43%) patients and in 21 (41%) out of 51 individuals with normal weight, 24 (44%) of over-weight and 7 (47%) of obese. In the group of 93 patients without erosive esophagitis and normal pH monitoring (29% male, median age 43 years), 26 (28%) had hiatal hernia and there were 43 (46%) individuals with normal weight, 38 (41%) with over-weight and 12 (13%) were obese. The number of patients with obesity and over-weight was significantly higher in the group with erosive esophagitis compared to the ones without erosive esophagitis. The prevalence of hiatal hernia was also superior in the erosive reflux disease patients. The reflux intensity and the prevalence of hiatal hernia were similar in patients with normal weight, over-weight and obesity in the group with erosive reflux disease and non-erosive reflux disease. CONCLUSION: There was a greater prevalence of obesity and over-weight in the group of patients with erosive esophagitis compared to patients with non-erosive reflux disease. There was no difference in reflux intensity measurements in any of the body mass index categories, in both groups. Although there was a major prevalence of hiatal hernia in the group of erosive reflux disease patients, this superiority was not extended to the categories of excessive weight in both groups.

Maior prevalência de obesidade na doença do refluxo gastroesofagiano erosiva / Higher prevalence of obesity in erosive gastroesophageal reflux disease

CONTEXTO: Existe uma noção geral de que indivíduos obesos desenvolvem mais freqüentemente a doença do refluxo gastroesofagiano, sendo a orientação de perder peso parte integrante do seu tratamento. Entretanto, uma base científica para esta associação não está plenamente estabelecida. OBJETIVOS: Avaliar a prevalência de obesidade e sobrepeso em pacientes com sintomas típicos de refluxo, com e sem esofagite erosiva. Analisar a prevalência de hérnia hiatal e a intensidade do refluxo anormal em relação ao índice de massa corporal nos dois grupos de pacientes. MÉTODOS: Foram examinadas retrospectivamente 362 pHmetrias de pacientes com pirose, todos com endoscopia digestiva alta prévia, definindo-se esofagite erosiva pela presença de erosões esofagianas macroscópicas e hérnia de hiato quando à junção esôfago-gástrica estava 2 cm ou mais acima do pinçamento diafragmático. Pacientes com esôfago de Barrett ou estenose péptica foram excluídos. A população foi dividida em três grupos de acordo com o índice de massa corpórea: peso normal, com índice de massa corporal entre 20 e 24,9, sobrepeso, com 25 e 29,9 e obesos com índice superior a 30. O diagnóstico de refluxo gastroesofagiano anormal com sua intensidade foi avaliado de acordo com os resultados de pHmetrias, analisados nos grupos de pacientes com e sem esofagite erosiva em relação ao índice de massa corporal. RESULTADOS: Entre os 362 pacientes, havia 148 (41 por cento) com e 214 (59 por cento) sem esofagite erosiva, sendo a pHmetria anormal em 100 por cento e 57 por cento dos pacientes, retrospectivamente. Entre os 148 (61 por cento do sexo masculino, mediana de idade de 50 anos), 41 (28 por cento) apresentavam peso normal, 82 (55 por cento) sobrepeso e 25 (17 por cento) eram obesos. Havia 88 (60 por cento) com hérnia hiatal, sendo 29 (71 por cento dos pacientes com peso normal), 45 (55 por cento dos com sobrepeso) e 14 (56 por cento dos obesos). Nos 121 indivíduos sem esofagite erosiva e...

Gastroesophageal reflux in cirrhotic patients with esophageal varices without endoscopic treatment.

BACKGROUND: Portal hypertension in patients with liver cirrhosis causes manifestations such as esophageal varices, ascites and edema. Some studies have been conducted about the role of esophageal varices in the development of esophageal motor disorders and abnormal gastroesophageal reflux in these patients. Ascites could be a factor promoting gastroesophageal reflux and it has been questioned whether reflux would favor the rupture of varices. However there are a few studies using ambulatory esophageal pH recording in the evaluation of these patients. AIMS: Evaluate gastroesophageal reflux by pH recording in cirrhotic patients with esophageal varices and possible predictors. METHODS: Fifty one patients (28 men, 23 women, mean age of 54 years) with liver cirrhosis, diagnosed by clinical, laboratorial, image and histological findings were prospectively evaluated. All patients had esophageal varices confirmed by endoscopy and were submitted to a questionnaire about typical gastroesophageal reflux disease symptoms (heartburn and or acid regurgitation). pH recording was performed with the probe placed 5 cm above the superior lower esophageal sphincter limit, as determined by manometry. Abnormal reflux (% total time with pH < 4 >4.5%) was related to the size of varices, congestive gastropathy, ascites, severity of cirrhosis and typical gastroesophageal reflux disease symptoms. RESULTS: The caliber of the varices was considered to be small in 30 patients (59%), medium in 17 (33%) and large in 4 (8%), 21 (41%) congestive gastropathy. Ascites was observed in 17 (33%), 32 patients (63%) were classified as Child-Pugh A, 17 (33%) Child-Pugh B and 2 (4%) Child-Pugh C. Twenty seven patients (53%) presented with typical gastroesophageal reflux disease symptoms. Abnormal reflux at pH recording was found in 19 patients (37%). One of them presented with erosive esophagitis at endoscopy. There was no relation between ascites, variceal size, congestive gastropathy and Child-Pugh score and abnormal reflux. There was a correlation between typical gastroesophageal reflux disease symptoms and abnormal reflux. CONCLUSION: Abnormal gastroesophageal reflux was found in 37% of the patients with hepatic cirrhosis and esophageal varices. Only typical gastroesophageal reflux disease symptoms predicted these findings.

RACIONAL: A hipertensão porta que acomete os pacientes com cirrose hepática é causa de varizes de esôfago, ascite e edema. Alguns estudos têm sido realizados para avaliar a importância das varizes de esôfago no desenvolvimento dos distúrbios motores esofagianos e do refluxo gastroesofágico anormal neste grupo de pacientes. A ascite pode ser um fator promotor de refluxo gastroesofágico e tem sido questionado se o refluxo anormal poderia favorecer a rotura das varizes de esôfago. Entretanto, são poucos os estudos que utilizam a pHmetria esofagiana prolongada ambulatorial na avaliação destes pacientes. OBJETIVO: Avaliar a presença de refluxo anormal a pHmetria esofagiana prolongada ambulatorial em pacientes cirróticos com varizes de esôfago e seus possíveis fatores preditivos. MÉTODOS: Cinqüenta e um pacientes (28 homens, 23 mulheres, média de idade de 54 anos) com cirrose hepática diagnosticada por métodos clínicos, laboratoriais, de imagem e histopatológicos foram avaliados de forma prospectiva. Todos os pacientes apresentavam varizes de esôfago à endoscopia digestiva alta e foram submetidos a um questionário para avaliação da presença de sintomas típicos da doença do refluxo gastroesofágico (pirose e/ou regurgitação ßcida). pHmetria esofagiana prolongada ambulatorial foi realizada posicionando-se o cateter 5 cm acima do limite superior do esfíncter esofagiano inferior, determinado previamente pela esofagomanometria. Refluxo anormal ( por cento tempo total com pH < 4 >4,5 por cento) foi relacionado com o tamanho das varizes, gastropatia congestiva, ascite, gravidade da cirrose e presença de sintomas típicos da doença do refluxo gastroesofágico. RESULTADOS: O calibre das varizes foi considerado pequeno em 30 pacientes (59 por cento), médio em 17 (33 por cento) e grosso em 4 (8 por cento), 21 (41 por cento) gastropatia congestiva. Ascite foi observada em 17 (33 por cento); 32 pacientes (63 por cento) foram classificados com Child-Pugh...
