Resultados funcionales de pacientes tratados con faringolaringectomía y reconstrucción faríngea con colgajo pediculado / Functional Outcomes using pedicle flap reconstruction approach after pharyngolaryngectomy in laryngeal carcinoma patients

INTRODUCCIÓN: La laringectomía total es el tratamiento de elección del cáncer de laringe avanzado, requiriendo en ocasiones asociar una resección parcial o total de la faringe para su manejo. El defecto faríngeo, puede repararse con colgajos libres o pediculados, teniendo estos últimos la ventaja de ser simples, confiables y resistentes a la radioterapia. OBJETIVO: Presentar los resultados funcionales de una serie de pacientes tratados con faringolaringectomía y reconstrucción faríngea con colgajo pediculado. MATERIAL Y MÉTODO: Se revisaron registros de pacientes con laringectomía total más faringectomía parcial y reconstrucción con colgajo pediculado en el Hospital Regional de Talca entre 2009 y 2017, encontrando 6 casos de los cuales 4 se encontraron vivos al momento de iniciar el estudio. Se realizó videofluoroscopía para evaluar deglución, presencia de estenosis y/o fístulas, además, de evaluación nutricional y encuesta de calidad de vida. RESULTADOS: En el estudio de la deglución por fluoroscopía, todos los pacientes presentaron escasa retención del material de contraste en la hipofaringe y esófago cervical, lo cual está en relación con cambios morfológicos posquirúrgicos, sin afectar significativamente el mecanismo deglutorio. Todos los pacientes se encontraron eutróficos en su evaluación nutricional y sin evidencias de alteración de su calidad de vida secundaria a la deglución. CONCLUSIONES: La reconstrucción faríngea parcial con colgajo pediculado en pacientes con laringectomías totales asociadas a faringectomía parcial permite una deglución adecuada y sin disfagia, con un estado nutricional eutrófico.

INTRODUCTION: Total laryngectomy is the treatment of choice for advanced laryngeal cancer and after radiotherapy failure. In patients with pharyngeal invasion, it is associated with total or partial pharyngectomy, wich defect can be repaired with free or pedicle flaps. AIM: To present a brief series of pedicle flap reconstruction approach after pharyngolaryngectomy in laryngeal carcinoma patients and functional outcomes MATERIALS AND METHOD: We looked at laryngeal cancer patient records who were treated with total laryngectomy with partial pharyngectomy and pharyngeal reconstruction with pedicle flap at "Hospital Regional de Talca" between the years 2009 and 2017, finding 6 cases, 4 of which were alive at the beginning of the study. We analized videoflourocopy swallow studies to assess mechanisms of deglutition, and presence of stenosis or fistulas. We also performed a nutritional state assessment and a quality of life questionnaire. RESULTS: During videodeglutition study, the 4 patients showed minimal contrast swallow delay at hypopharynx and cervical esophagus. All the patients were found eutrophic in their nutritional assessment and with no significant evidence of quality of life disturbances secondary to deglutition state. CONCLUSIONS: Partial pharyngeal reconstruction using pedicle flaps in patients who underwent total laryngectomy with partial pharyngectomy allows to maintain an adequate deglutition without dysphagia, as well as a good nutritional state.

Efficacy and safety of "coronary artery bypass graft angiography" with right transradial access versus left transradial access and femoral access: a retrospective comparative study

Abstract Objective: Over the past 10 years, the rate of patients who have undergone coronary artery bypass graft (CABG) surgery has increased twofold in cases of coronary angiography. Today, transradial access is the first choice for coronary angiography. We aimed to compare the efficacy and reliability of radial versus femoral access for coronary angiography in post-CABG surgery in this study. Methods: Data from 442 patients who underwent post-CABG surgery between 2012-2017 were retrospectively compared. The right radial route was used in 120 cases, the left radial route in 148, and femoral route in 174. These three pathways were compared in terms of procedure time and fluoroscopy time, efficacy, and complication development. Comparisons among the three groups were performed with Bonferroni test for continuous variables and chi-square or Fisher's exact test for nominal variables as a binary. Results: Comparison results indicate that femoral access was better than left radial access and the left radial access was better than right radial access in terms of fluoroscopy time (10.71±1.65, 10.94±1.25, 16.12±5.28 min, P<0.001) and total procedure time (17.28±1.68, 17.68±2.34, 23.04±5.84 min, P<0.001). The left radial pathway was the most effective way of viewing left internal mammary artery (LIMA). No statistically significant differences were found among the three groups in other graft visualizations, all minor complications, total procedure and fluoroscopy time "Except LIMA imaging". Mortality due to processing was not observed in all three groups. Conclusion: The left radial route is preferred over right radial access for post-CABG angiography because the left radial pathway is close to the LIMA and is similar to the femoral pathway. In LIMA graft imaging, right radial access is a reliable route, even though it is not as effective as other pathways. We hope that the right radial pathway will improve with physician experience and innovations.

Screening protocol for dysphagia in adults: comparison with videofluoroscopic findings

OBJECTIVES: To compare the videofluoroscopic findings of patients with suspected oropharyngeal dysphagia with the results of a clinical screening protocol. METHODS: A retrospective observational cohort study was conducted on all consecutive patients with suspected oropharyngeal dysphagia between March 2015 and February 2016 who were assigned to receive a videofluoroscopic assessment of swallowing. All patients were first submitted to videofluoroscopy and then to the clinical assessment of swallowing. The clinical assessment was performed within the first 24 hours after videofluoroscopy. The videofluoroscopy results were analyzed regarding penetration/aspiration using an 8-point multidimensional perceptual scale. The accuracy of the clinical protocol was analyzed using the sensitivity, specificity, likelihood ratios and predictive values. RESULTS: The selected sample consisted of 50 patients. The clinical protocol presented a sensitivity of 50% and specificity of 95%, with an accuracy of 88%. "Cough" and "wet-hoarse" vocal quality after/during swallowing were clinical indicators that appeared to correctly identify the presence of penetration/aspiration risk. CONCLUSION: The clinical protocol used in the present study is a simple, rapid and reliable clinical assessment. Despite the absence of a completely satisfactory result, especially in terms of the sensitivity and positive predictive values, we suggest that lower rates of pneumonia can be achieved using a formal dysphagia screening method.

Cateteres venosos centrais de inserção periférica: alternativa ou primeira escolha em acesso vascular? / Peripherally inserted central venous catheters: alternative or first choice vascular access?

Contexto: Os cateteres venosos centrais de inserção periférica (PICC) são dispositivos intravenosos, introduzidos através de uma veia superficial ou profunda da extremidade superior ou inferior até o terço distal da veia cava superior ou proximal da veia cava inferior. Apresentam maior segurança para infusão de soluções vesicantes/irritantes e hiperosmolares, antibioticoterapia, nutrição parenteral prolongada (NPT) e uso de quimioterápicos; demonstram reduzido risco de infecção em comparação a outros cateteres vasculares e maior relação custo/benefício se comparados ao cateter venoso de inserção central (CVCIC). Objetivos: Apresentar os resultados de implantes de PICCs ecoguiados e posicionados por fluoroscopia realizados no Hospital e Maternidade São Luiz (HMSL) Itaim, Rede D'or, Brasil. Métodos: Estudo prospectivo, não randomizado, realizado entre fevereiro de 2015 e novembro de 2016. Utilizou-se protocolo pré-estabelecido pela instituição em casos de solicitação de acesso vascular. Foram analisadas indicações, doenças prevalentes, tipo do cateter implantado, sucesso técnico, complicações relacionadas ao cateter, e estabelecidos critérios de inclusão e exclusão. Resultados: Solicitados 256 acessos vasculares, sendo implantados 236 PICCs (92,1%) e 20 CVCICs (7,9%). Principais indicações: antibioticoterapia prolongada (52,0%), NPT (19,3%) e acesso venoso difícil (16,0%). Houve sucesso técnico em 246 cateteres implantados (96,1%). A veia basílica direita foi a principal veia puncionada em 192 pacientes (75,0%), seguida da braquial direita em 28 pacientes (10,9%). Conclusões: O implante dos PICCs ecoguiados e posicionados por fluoroscopia demonstrou baixa incidência de complicações, reduzidos índices de infecção e é seguro e eficaz em casos de acessos vasculares difíceis, sendo esses cateteres considerados dispositivos de escolha em acesso vascular central

Background: Peripherally inserted central catheters (PICC) are intravenous devices inserted through a superficial or deep vein of an upper or lower extremity and advanced to the distal third of the superior vena cava or proximal third of the inferior vena cava. They offer the advantages of greater safety for infusion of vesicant/irritant and hyperosmolar solutions and enable administration of antibiotics, prolonged parenteral nutrition (PPN), and chemotherapy agents. They also involve reduced risk of infection compared to other vascular catheters and are more cost-effective than centrally inserted venous catheters (CICVC). Objectives: To present the results of our team's experience with US-guided and fluoroscopy-positioned PICC placement at the Hospital and Maternidade São Luiz (HMSL) Itaim, Rede D'or, Brazil. Methods: This was a prospective, non-randomized study, conducted from February 2015 to November 2016. The institution's preestablished protocol was followed when vascular access was requested. Indications, prevalent diseases, type of catheter implanted, technical success, and complications related to the catheters were analyzed and inclusion and exclusion criteria are described. Results: A total of 256 vascular accesses were requested, and 236 PICCs (92.1%) and 20 CICVCs (7.9%) were implanted. The main indications were as follows: prolonged antibiotic therapy (52%), PPN (19.3%), and difficult venous access (16%). Technical successes was achieved in 246 catheter placements (96.1%). The right basilic vein was the most common vein punctured for access, in 192 patients (75%), followed by the right brachial vein, in 28 patients (10.9%). Conclusions: Ultrasound-guided and fluoroscopy-positioned PICC placement had a low incidence of complications, reduced infection rates, and proved safe and effective in cases of difficult vascular access. PICCs can be considered the devices of choice for central vascular access

A prospective multicenter European study on flexible ureterorenoscopy for the management of renal stone

ABSTRACT Purpose The aim of this study was to describe the outcomes and the complications of retrograde intrarenal surgery (RIRS) for renal stones in a multi-institutional working group. Materials and Methods From 2012 to 2014, we conducted a prospective study including all RIRS performed for kidney stones in 4 European centers. Demographic information, disease characteristics, and perioperative and postoperative data were gathered. Patients and stone data, procedure characteristics, results and safety outcomes were analyzed and compared by descriptive statistics. Complications were reported using the standardized Clavien system. Results Three hundred and fifty-six patients underwent 377 RIRS with holmium laser lithotripsy for renal stones. The RIRS was completed in all patients with a mean operative time of 63.5 min. The stone-free status was confirmed endoscopically and through fluoroscopic imaging after the first procedure in 73.6%. The second procedure was performed in twenty patients (5.6%) achieving an overall stone free rate of 78.9%. The overall complication rate was 15.1%. Intra-operative and post-operative complications were seen in 24 (6.7%) and 30 (8.4%) cases, respectively. Conclusions RIRS is a minimally invasive procedure with good results in terms of stone-free and complications rate.

The effectiveness of the head-turn-plus-chin-down maneuver for eliminating vallecular residue

ABSTRACT Purpose When swallowing efficiency is impaired, residue accumulates in the pharynx. Cued or spontaneous swallows in the head neutral position do not always successfully clear residue. We investigated the impact of a novel maneuver on residue clearance by combining a head turn with the chin down posture. Methods Data were collected from 26 participants who demonstrated persistent vallecular residue after an initial head neutral clearance swallow in videofluoroscopy. Participants were cued to perform a head-turn-plus-chin-down swallow, with the direction of head turn randomized. Pixel-based measures of residue in the vallecular space before and after the maneuver were made on still frame lateral images using ImageJ software. Measures of % full and the Normalized Residue Ratio Scale (NRRS) were extracted. Univariate analyses of variance were used to detect significant reductions in residue. Results On average, pre-maneuver measures showed residue filling 56-73% of the valleculae, depending on stimulus consistency (NRRS scores: 0.2-0.4). More than 80% of pre-swallow measures displayed NRRS ratios > 0.06, a threshold previously linked to increased risk of post-swallow aspiration. Conclusion The head-turn-plus-chin-down maneuver achieved significant reductions in residue for thin and nectar-thick fluids, suggesting that this maneuver can be effective in reducing persistent vallecular residue with these consistencies.

Sphenopalatine ganglion pulsed radiofrequency treatment in patients suffering from chronic face and head pain / Tratamento com radiofrequência pulsada para gânglio esfenopalatino em pacientes com dor crônica de face e cabeça

PURPOSE: There are various facial pain syndromes including trigeminal neuralgia, trigeminal neuropathic pain and atypical facial pain syndromes. Effectiveness of the pulsed radiofrequency in managing various pain syndromes has been clearly demonstrated. There are a limited number of studies on the pulsed radiofrequency treatment for sphenopalatine ganglion in patients suffering from face and head pain. The purpose of this study is to evaluate the satisfaction of pulsed radiofrequency treatment at our patients retrospectively. METHODS: Infrazygomatic approach was used for the pulsed radiofrequency of the sphenopalatine ganglion under fluoroscopic guidance. After the tip of the needle reached the target point, 0.25-0.5 ms pulse width was applied for sensory stimulation at frequencies from 50 Hz to 1 V. Paraesthesias were exposed at the roof of the nose at 0.5-0.7 V. To rule out trigeminal contact that led to rhythmic mandibular contraction, motor stimulation at a frequency of 2 Hz was applied. Then, four cycles of pulsed radiofrequency lesioning were performed for 120 s at a temperature of 42 °C. RESULTS: Pain relief could not be achieved in 23% of the patients (unacceptable), whereas pain was completely relieved in 35% of the patients (excellent) and mild to moderate pain relief could be achieved in 42% of the patients (good) through sphenopalatine ganglion-pulsed radiofrequency treatment. CONCLUSION: Pulsed radiofrequency of the sphenopalatine ganglion is effective in treating the patients suffering from intractable chronic facial and head pain as shown by our findings. There is a need for prospective, randomized, controlled trials in order to confirm the efficacy and safety of this new treatment modality in chronic head and face pain.

OBJETIVO: Existem várias síndromes de dor facial, incluindo neuralgia trigeminal, dor neuropática trigeminal e síndromes atípicas de dor facial. A eficácia da radiofrequência pulsada (RFP) para o manejo de várias síndromes de dor foi claramente demonstrada. Há um número limitado de estudos sobre o tratamento com RFP para gânglio esfenopalatino (GEP) em pacientes que sofrem de dor facial e de cabeça. O objetivo deste estudo foi avaliar a satisfação do tratamento com PRF em nossos pacientes, retrospectivamente. MÉTODOS: A abordagem infrazigomática foi usada para a RFP do GEP sob orientação fluoroscópica. Depois de a ponta da agulha atingir o ponto alvo, pulsos de 0,25 a 0,5 ms foram aplicados para a estimulação sensorial em frequências de 50 Hz a 1 V. Parestesias foram expostas no teto do nariz em 0,5 a 0,7 V. Para excluir o contato trigeminal que levou à contração mandibular rítmica, a estimulação motora foi aplicada na frequência de 2 Hz. Em seguida, quatro ciclos de RFP foram feitos durante 120 segundos a uma temperatura de 42 °C. RESULTADOS: O alívio da dor não foi obtido em 23% dos pacientes (inaceitável); enquanto a dor foi totalmente aliviada em 35% dos pacientes (excelente) e o alívio de leve a moderado da dor foi obtido em 42% dos pacientes (bom), com o tratamento RFP-GEP. CONCLUSÃO: RFP para GEP é eficaz no tratamento de pacientes que sofrem de dor crônica intratável, facial e de cabeça, como mostrado por nossas descobertas. Estudos prospectivos, randômicos e controlados são necessários para confirmar a eficácia e segurança dessa nova modalidade de tratamento para dor crônica facial e de cabeça.

Deglutição orofaríngea na insuficiência renal crônica / Oropharyngeal swallowing in chronic renal failure

RESUMO Objetivo: Caracterizar o perfil de deglutição orofaríngea em indivíduos com insuficiência renal crônica (IRC). Métodos: Estudo clínico transversal do qual participaram 20 indivíduos adultos com diagnóstico médico de IRC, durante o período de internação hospitalar. A avaliação objetiva da deglutição foi realizada por videofluoroscopia de deglutição (VFD), sendo a caracterização e classificação dos achados baseada em parâmetros de eficácia e segurança. Além disso, foi aplicada a Functional Oral Intake Scale (FOIS). Resultados: A análise da VFD mostrou que 16indivíduos apresentaram alteração de fase oral e faríngea, três indivíduos apresentaram alterações somente de fase faríngea e um indivíduo apresentou alterações exclusivas de fase oral da deglutição. Além disso, por meio da VFD foi constatada penetração e aspiração laringotraqueal em 30% dos indivíduos. Previamente à realização da VFD, foi verificado que quatro indivíduos (20%) encontravam-se no nível 5 da FOIS, enquanto 16 indivíduos (80%) encontravam-se no nível 7. Após as adequações de alteração da consistência da dieta via oral devido aos prejuízos de segurança e à eficiência da deglutição, a classificação da FOIS passou a representar 6 indivíduos no nível 1, 7 no nível 4, 4 no nível 5 e 3 no nível 6. Conclusão: A caracterização do perfil de deglutição orofaríngea em indivíduos com IRC mostrou alterações de fase oral e faríngea, inclusive com penetração e aspiração laringotraqueal, com necessidade de mudanças no nível de ingestão oral.

ABSTRACT Objective: To characterize the oropharyngeal swallowing profile of patients with chronic renal failure. Methods: A cross-sectional clinical study involving 20 adults diagnosed with chronic renal failure in hospital stay was conducted. The evaluation of swallowing was performed by videofluoroscopy, and characterization of findings was based on effectiveness and safety parameters. Functional Oral Intake Scale (FOIS) was also applied. Results: On videofluoroscopy, 16 patients presented changes in oral and pharyngeal patterns, three individuals presented impairment at the pharyngeal phase, and only one individual presented changes only at the oral phase of swallowing. Furthermore, videofluoroscopy showed penetration and tracheal aspiration in 30% of the sample. Before the videofluoroscopy, four individuals (20%) were at level 5 of FOIS scale, whereas 16 individuals (80%) were at level 7. After adjustments of the oral diet consistency because of safety and swallowing effectiveness, FOIS classification was six individuals at level 1, seven at level 4, four at level 5, and three at level 6. Conclusion: The characterization of oropharyngeal swallowing profile in chronic renal patients showed abnormalities at oral and pharyngeal phase, including penetration and tracheal aspiration, which requires oral intake changes.

Does Ad Hoc Coronary Intervention Reduce Radiation Exposure? – Analysis of 568 Patients / Intervenção Coronariana Ad Hoc Reduz a Exposição Radiológica? - Análise em 568 Pacientes

Background:Advantages and disadvantages of ad hoc percutaneous coronary intervention have been described. However little is known about the radiation exposure of that procedure as compared with the staged intervention.Objective:To compare the radiation dose of the ad hoc percutaneous coronary intervention with that of the staged procedureMethods:The dose-area product and total Kerma were measured, and the doses of the diagnostic and therapeutic procedures were added. In addition, total fluoroscopic time and number of acquisitions were evaluated.Results:A total of 568 consecutive patients were treated with ad hoc percutaneous coronary intervention (n = 320) or staged percutaneous coronary intervention (n = 248). On admission, the ad hoc group had less hypertension (74.1% vs 81.9%; p = 0.035), dyslipidemia (57.8% vs. 67.7%; p = 0.02) and three-vessel disease (38.8% vs. 50.4%; p = 0.015). The ad hoc group was exposed to significantly lower radiation doses, even after baseline characteristic adjustment between both groups. The ad hoc group was exposed to a total dose-area product of 119.7 ± 70.7 Gycm2, while the staged group, to 139.2 ± 75.3 Gycm2 (p < 0.001).Conclusion:Ad hoc percutaneous coronary intervention reduced radiation exposure as compared with diagnostic and therapeutic procedures performed at two separate times.

Fundamento:Uma série de vantagens e desvantagens tem sido descrita para a intervenção coronária percutânea ad hoc, como a realizada ao mesmo tempo que o cateterismo diagnóstico, porém pouco se sabe sobre a exposição radiológica desse procedimento, comparado com a intervenção estadiada, ou seja, em dois momentos.Objetivo:Comparar a dose de radiação utilizada na angioplastia ad hoc com a angioplastia estadiada.Métodos:O produto de dose por área e o Kerma total foram mensurados, somando-se ambas as fases de diagnóstico e terapêutica. Além disso, foram computados o tempo total de fluoroscopia e o número de filmagens.Resultados:Um total de 568 pacientes consecutivos foram tratados com intervenção coronária percutânea ad hoc (n = 320) ou estadiada (n = 248). À admissão, o grupo do ad hoc apresentava menos hipertensão (74,1% vs. 81,9%; p = 0,035), dislipidemia (57,8% vs. 67,7%; p = 0,02) e doença triarterial (38,8% vs. 50,4%; p = 0,015). O grupo ad hoc foi exposto a doses significativamente menores de radiação, mesmo após ajuste para as diferenças basais entre os grupos. O grupo ad hoc foi exposto a uma dose de produto de dose por área total de 119,7 ± 70,7 Gycm2 enquanto que os pacientes estadiados foram expostos a uma dose de 139,2 ± 75,3 Gycm2 (p < 0,001).Conclusão:A intervenção coronária percutânea ad hoc reduziu a exposição radiológica, em comparação com procedimentos diagnósticos e terapêuticos realizados em tempos separados.

Comparação entre as vias de acesso femoral e radial em procedimentos coronários invasivos após cirurgia de revascularização miocárdica / Comparison between femoral and radial approach in invasive coronary

Procedimentos coronários invasivos são comuns em pacientes com revascularizaçãomiocárdica cirúrgica prévia. Dados acerca do real papel e das possíveis limitações do acesso radial nesse subgrupo de pacientes são infrequentes. O objetivo deste estudo foi avaliar a factibilidade e a segurança do acesso radial em pacientes revascularizados cirurgicamente e que foram submetidos a procedimentos coronários invasivos diagnósticos ou terapêuticos subsequentes, comparando-o ao acesso femoral. Métodos: Entre maio de 2008 e novembro de 2014, foram analisados 959 procedimentos, sendo 539 realizados pelo acesso radial e 420 pelo femoral. Todos os operadores estavam familiarizados com ambos os acessos vasculares, cabendo a eles a decisão final sobre a via a ser utilizada. Resultados: A prevalência de insucesso foi de 6,1% vs. 0,5% (p < 0,0001), favorecendo a técnica femoral. As taxas de eventos cardíacos adversos graves (0,4% vs. 0,7%) e de complicações vasculares (1,5% vs. 1,9%)foram baixas, sem diferença entre os grupos. A opção pela técnica radial implicou em maior tempo de fluoroscopia e necessidade de cruzamento entre vias de acesso, principalmente em procedimentos diagnósticos. Conclusões: O acesso radial representou uma opção segura e eficaz para a realização de procedimentos coronários invasivos em pacientes cirurgicamente revascularizados, notadamente para os procedimentos terapêuticos...

Invasive coronary procedures are common in patients with previous coronary artery by-pass graft surgery. Data on the actual role and possible limitations of the radial approach in this subgroup of patients are sparse. The objective of this study was to evaluate the feasibility and safety of radial accessin patients surgically revascularized and who under went subsequent invasive diagnostic or therapeutic coronary procedures, comparing it to the femoral access. Methods: Between May 2008 and November 2014, 959 procedures were included; 539 performed by radial access and 420 by femoral access. All operators were familiar with both vascular accesses, and the final decision on the route to be used was left to the operators discretion. Results: The failure rate was 6.1% vs. 0.5% (p < 0.0001), favoring the femoral approach. Major adverse cardiac events (0.4% vs. 0.7%) and vascular complications (1.5% vs. 1.9%) rates were low, with no difference between groups. The choice of the radial approach resulted in greater fluoroscopy time and crossover rate between access routes, especially in diagnostic procedures. Conclusions: The radial approach was a safe and effective option for invasive coronary procedures in post coronary artery bypass graft patients, especially for therapeutic procedures...

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. .

Pharyngeal swallowing phase and chronic cough

Introduction: The act of swallowing depends on a complex and dynamic process which uses common structures to the act of breathing; respiratory problems can cause swallowing difficulties. Aim: To assess the swallowing pharyngeal phase in patients with chronic cough. Method: Retrospective study with 15 patients of both genders, patients with chronic cough and risk factors for aspiration defined by the pneumologic diagnosis. The patients were submitted to anamnesis on complaints related to swallowing, chewing and breathing, or related to food and to videofluoroscopic examination. Results: It was observed that 33.3% had normal and functional swallowing, being the last one of most prevalence. The mild dysphagia was observed in 20% of the patients, the mild to moderate dysphagia in 6.7% of them. In relation to the Rosenbek scale, 73.3% of patients presented degree 1, 6.7% presented degrees 2 and 3, and 13.3% presented degree 8. The most found pathology was the chronic cough with 40%, followed by asthma with 20%; 69.2% of patients presented stasis and of these, five used protection maneuvers, of these, seven were effective and only three were used in the presence of stasis. The most used maneuver was the multiple swallowing, being effective in 100%. Conclusion: There are peculiarities in the patients' swallowing with chronic cough that, although not presenting complaints relating to swallowing, it presents an important aspiration risk due to the presence of changes in breathing pattern that can intervene in the coordination between breathing and swallowing, which is essential to protect the lower airway...

Lateral laryngopharyngeal diverticula: a videofluoroscopic study of laryngopharyngeal wall in wind instrumentalists / Divertículo faríngeo-lateral: estudo videofluoroscópico da laringofaringe em instrumentistas de sopro

CONTEXT: This paper analyze healthy musicians who play wind instruments. OBJECTIVE: To identify possible diverticular formations on the laryngopharyngeal wall produced by pharyngeal overpressure during the use of these instruments. METHODS: Through a videofluoroscopic method, 22 professional musicians had their pharynx analyzed in frontal face and profile, by swallowing 20 mL of barium sulfate solution and blowing against resistance. RESULTS: All the volunteers showed lateral laryngopharyngeal diverticula (3 unilateral and 19 bilateral) with areas ranging from 0.7 to 6 cm². Trumpet and clarinet players showed larger diverticula, on both the right and left sides. Any important complaints were noted spontaneously or after questions. In the barium-swallow analyses, the 41 diverticula previously identified in the blowing tests were not seen or appeared to be smaller, because of the free flux passage from the pharynx to the esophagus. Despite the existence of the other, less resistant areas on the laryngopharyngeal segment, no other protrusions could be found in this group of wind instrumentalists. CONCLUSIONS: The lateral laryngopharyngeal diverticula that occur in blow instrumentalists is distinct of diverticula produced by laryngopharyngeal overpressure determined by abnormally high resistance to flux passage from pharynx to esophagus. In musicians is the persistent and continuous pharyngeal overpressure induced by the resistance of the instrument's mouthpiece will strongly distend the anatomically less resistant areas of the pharynx, producing a large protrusion. Laryngopharyngeal overpressure without abnormal resistance to flux passage explain the way blow instrumentalists protrusions did not appear as full sacs in a barium-swallow test, despite their larger dimensions. As final conclusion the musician-acquired diverticula must be considered as an "occupational overuse syndrome".

CONTEXTO: São apresentados os resultados de um estudo em profissionais sadios, instrumentistas de sopro. OBJETIVO: Identificar possíveis formações diverticulares produzidas nas paredes da laringofaringe pela alta pressão que a distende durante o uso desses instrumentos. MÉTODOS: Utilizando o método videofluoroscópico examinou-se a faringe de 22 músicos profissionais nas incidências frontais e perfil com deglutição de 20 mL de solução de sulfato de bário e após, soprando contra resistência. RESULTADOS: Em todos os voluntários detectou-se a presença de divertículo faríngeo-lateral (3 unilaterais e 19 bilaterais) com áreas de projeção variando de 0,7 a 6 cm². Trompetistas e clarinetistas apresentaram divertículos grandes e bilaterais. Nenhuma queixa importante foi referida espontaneamente ou mesmo após questionamento. No estudo baritado da deglutição ou não se detectaram ou se detectaram com pequena dimensão, devido à livre passagem do fluxo de contraste para o esôfago, os 41 divertículos identificados quando os músicos sopraram contra resistência. Embora existam na laringofaringe outras áreas anatomicamente menos resistentes, nenhuma delas apresentou protrusão no grupo de instrumentistas de sopro estudado. CONCLUSÕES: A formação diverticular lateral que ocorre nos instrumentistas de sopro é distinta daquela que ocorre por aumento da pressão laringofaríngea determinada por resistência anormalmente elevada à livre passagem do fluxo para o esôfago. As formações diverticulares laterais nos instrumentistas devem-se ao prolongado e repetitivo supranormal aumento da pressão laringofaríngea produzida pelo sopro contra resistência. A ausência, durante a deglutição, de resistência aumentada ao fluxo do meio de contraste em passagem para o esôfago explica o fato de os divertículos de maior dimensão, identificados pela distensão por ar, não apresentarem retenção da solução de sulfato de bário em seu interior durante a deglutição. Pode-se ainda concluir, com base na presença em 100% dos casos, que os divertículos faríngeo-laterais observados nos instrumentistas de sopro constituem-se em síndrome de sobrecarga funcional.
