Although dysphagia is an important symptom associated with prognosis in patients with Parkinson's disease (PD), dysphagia tends to be overlooked until swallowing difficulties reach an advanced phase. We assessed dysphagia with videofluoroscopic examination of swallowing in 31 patients with mainly mild or moderate PD. Swallowing problems were observed in the pharyngeal phase in 28 patients, oral phase in 19 patients, esophageal phase in 15 patients, and oral preparatory phase in 1 patient. Therefore, dysphagia in the pharyngeal phase was observed in almost all patients with mild or moderate PD. In contrast, no dysfunction was detected in most patients when screening was conducted via questionnaire or other methods. Assessment of clinical parameters in the present study suggests that latent swallowing dysfunction may be present even in the early disease stage in PD. A future prospective study to follow swallowing functions in a pre-symptomatic phase in PD would be fruitful to find whether swallowing dysfunction is one of the prodromal symptoms.

Dysphagia is a common problem in children with repaired oesophageal atresia (OA). Abnormalities in the oropharyngeal and oesophageal phase have hardly been studied. The aims of this study were to assess the prevalence of dysphagia in children with repaired OA and to identify and differentiate oral and pharyngeal dysphagia based on videofluoroscopic swallow study (VFSS) findings in a limited number of children in this cohort. Medical records of 111 patients, born between January 1996 and July 2013 and treated at the Radboudumc Amalia Children's Hospital, were retrospectively reviewed. The prevalence of dysphagia was determined by the objective and modified Functional Oral Intake Scale (FOIS) in four age groups. The first performed VFSS of 12 children was structurally assessed. The prevalence of dysphagia was 61 of 111 patients (55 %) in age group <1 year. In age group 1-4, 5-11 and 12-18 years, the prevalence of dysphagia decreased from 54 of 106 (51 %) patients to 11 of 64 (17 %) and 5 of 24 (21 %) patients. The 12 VFSS's reviews revealed oral dysphagia in 36 % and pharyngeal dysphagia in 75 %. This study highlights dysphagia as an important problem in different age groups of children with repaired OA. Furthermore, our study shows the presence of oropharyngeal dysphagia in this population. This study emphasizes the need to standardize the use of objective dysphagia scales, like the modified FOIS, to provide a careful follow-up of children with repaired OA. • Prevalence of dysphagia in children with repaired oesophageal atresia varies widely (ranges from 45 to 70 %) in literature. • Oral, pharyngeal and oesophageal dysphagia require different treatment approaches. What is New: • We determined dysphagia based on functional oral intake and provide an overview of change in dysphagia prevalence and severity over time in children with repaired OA. • Our study shows that dysphagia, including oropharyngeal dysphagia, is highly prevalent in young children

Objective To determine the cutoff value of the pharyngeal residue for predicting reduction of aspiration, by measuring the residue of valleculae and pyriformis sinuses through videofluoroscopic swallowing studies (VFSS) after treatment with neuromuscular electrical stimulator (VitalStim) in stroke patients with dysphagia. Methods VFSS was conducted on first-time stroke patients before and after the VitalStim therapy. The results were analyzed for comparison of the pharyngeal residue in the improved group and the non-improved group. Results A total of 59 patients concluded the test, in which 42 patients improved well enough to change the dietary methods while 17 did not improve sufficiently. Remnant area to total area (R/T) ratios of the valleculae before treatment in the improved group were 0.120, 0.177, and 0.101 for solid, soft, and liquid foods, respectively, whereas the ratios for the non-improved group were 0.365, 0.396, and 0.281, respectively. The ratios of the pyriformis sinuses were 0.126, 0.159, and 0.121 for the improved group and 0.315, 0.338, and 0.244 for the non-improved group. The R/T ratios of valleculae and pyriformis sinus were significantly lower in the improved group than the non-improved group in all food types before treatment. The R/T ratio cutoff values were 0.267, 0.250, and 0.185 at valleculae and 0.228, 0.218, and 0.185 at pyriformis sinuses. Conclusion In dysphagia after stroke, less pharyngeal residue before treatment serves as a factor for predicting greater improvement after VitalStim treatment. PMID:25379490

The inability to swallow, or dysphagia, is a debilitating and life-threatening condition that arises with ageing or disease. Dysphagia results from neurological or muscular impairment of one or more pharyngeal muscles, which function together to ensure proper swallowing and prevent the aspiration of food or liquid into the lungs. Little is known about the effects of age or disease on pharyngeal muscles as a group. Here we show ageing affected pharyngeal muscle growth and atrophy in wild-type mice depending on the particular muscle analysed. Furthermore, wild-type mice also developed dysphagia with ageing. Additionally, we studied pharyngeal muscles in a mouse model for oculopharyngeal muscular dystrophy, a dysphagic disease caused by a polyalanine expansion in the RNA binding protein, PABPN1. We examined pharyngeal muscles of mice overexpressing either wild-type A10 or mutant A17 PABPN1. Overexpression of mutant A17 PABPN1 differentially affected growth of the palatopharyngeus muscle dependent on its location within the pharynx. Interestingly, overexpression of wild-type A10 PABPN1 was protective against age-related muscle atrophy in the laryngopharynx and prevented the development of age-related dysphagia. These results demonstrate that pharyngeal muscles are differentially affected by both ageing and muscular dystrophy in a region-dependent manner. These studies lay important groundwork for understanding the molecular and cellular mechanisms that regulate pharyngeal muscle growth and atrophy, which may lead to novel therapies for individuals with dysphagia.

Aspiration is an often unrecognized comorbidity in children with Down syndrome with serious medical consequences. This retrospective chart review of swallow study reports characterizes oral and pharyngeal phase dysphagia and diet modifications on videofluoroscopic swallow studies (VFSS) in a large cohort of children with Down syndrome. A total of 158 pediatric patients (male = 95; female = 63; mean age 2.10 years, SD 3.17 years) received an initial VFSS at a pediatric teaching hospital as part of their medical care. A total of 56.3 % (n = 89) children had pharyngeal phase dysphagia with aspiration and deep laryngeal penetration occurring most frequently. Of the 61 patients who aspirated, 90.2 % (n = 55) did so silently with no cough or overt clinical symptoms. In 76.7 % of cases of pharyngeal phase dysphagia, a functional feeding plan, with use of thickened liquids or change in feeding system to control flow rate and/or bolus size, was able to be established, which allowed children to continue eating by mouth. Thickened liquids (76.7 %, n = 46) were the most effective adaptation, with change in feeding system alone effective in only 8.3 % (n = 5) cases. Oral phase dysphagia was reported in the majority of patients (63.8 %, n = 88/138); however, this was not predictive of pharyngeal phase dysphagia. Age, sex, and reason for referral, including prior clinical symptoms, did not have a statistically significant impact on the presence of dysphagia. This comprehensive review has application to clinical understanding and management of dysphagia in children with Down syndrome.

Dysphagia after anterior cervical discectomy and fusion (ACDF) is common, with a prevalence ranging between 28% and 57% of cases. However, nearly all cases resolve spontaneously within 2 years, thus identifying patients who require more detailed or invasive work-up is a challenging task for clinicians. A review of literature reveals a paucity of case reports detailing work-up and successful management options. The authors performed a clinical and radiographic review of a case of a 47-year-old female who presented with persistent dysphagia 3 years following anterior cervical spine surgery and was found to have an erosive pharyngeal defect with exposed spinal hardware. The diagnosis was made with direct laryngoscopy and treatment consisted of plate removal and pharyngeal repair, followed by revision fusion with deformity correction. This case and the accompanying pertinent review of the literature highlight the importance of a thorough evaluation of dysphagia, especially in the mid- and late-term postoperative period following ACDF, when most cases of dysphagia should have been resolved. Correctly identifying the underlying etiology of dysphagia may lead to improved revision of ACDF outcomes. Unresolved dysphagia should be a red flag for surgeons as it may be the presentation of erosive esophageal/pharyngeal damage, a rare but serious complication following ACDF.

In order to differentiate the features of dysphagia that occur after supraglottic horizontal laryngectomy from those that occur during neurologic diseases, we divided 38 subjects into 3 groups and submitted them to oropharyngoesophageal scintigraphy. Group 1 (control group) included 15 healthy volunteeers; group 2 comprised 8 patients who had residual dysphagia at least 1 year after supraglottic laryngectomy; and group 3 included 15 patients with various neurologic and neuromuscular disorders. In group 1, the mean values (+/- 2 SD) of selected semiquantitative parameters were consistent with those reported in the literature for normal subjects. In group 2, oral, pharyngeal, and esophageal transit times were not significantly altered, and moderate tracheobronchial post-deglutitive aspiration was present (maximum value, 6.7%; mean value, 2.04%). The pharyngeal retention index was significantly increased (p = .0003) as compared to normal subjects in all cases (maximum value, 40%; mean value, 23%) and was associated in all cases with slight but consistent post-deglutitive aspiration. In group 3, the oral and esophageal phases were significantly prolonged and the retention indices were significantly increased. Statistical analysis documented a significant increase in oral transit time (p = .003), esophageal transit time (p = .01), oral retention index (p = .006), pharyngeal retention index (p = .0007), and esophageal retention index (p = .009) as compared to normal subjects. The swallowing pattern was also altered by 1) an early loss of the bolus from the oral cavity; 2) bolus fragmentation due to double or triple deglutition, reduced lingual propulsion, or the return of a small part of the bolus into the oral cavity during deglutition; and/or 3) double pharyngeal peaks in the activity-time curves. Tracheobronchial aspiration (maximum value, 90%; mean value, 9.70%) was present in some cases, mainly in patients affected by post-stroke dysphagia. On the basis of the

Objective To compare swallowing function between healthy subjects and patients with pharyngeal dysphagia using high resolution manometry (HRM) and to evaluate the usefulness of HRM for detecting pharyngeal dysphagia. Methods Seventy-five patients with dysphagia and 28 healthy subjects were included in this study. Diagnosis of dysphagia was confirmed by a videofluoroscopy. HRM was performed to measure pressure and timing information at the velopharynx (VP), tongue base (TB), and upper esophageal sphincter (UES). HRM parameters were compared between dysphagia and healthy groups. Optimal threshold values of significant HRM parameters for dysphagia were determined. Results VP maximal pressure, TB maximal pressure, UES relaxation duration, and UES resting pressure were lower in the dysphagia group than those in healthy group. UES minimal pressure was higher in dysphagia group than in the healthy group. Receiver operating characteristic (ROC) analyses were conducted to validate optimal threshold values for significant HRM parameters to identify patients with pharyngeal dysphagia. With maximal VP pressure at a threshold value of 144.0 mmHg, dysphagia was identified with 96.4% sensitivity and 74.7% specificity. With maximal TB pressure at a threshold value of 158.0 mmHg, dysphagia was identified with 96.4% sensitivity and 77.3% specificity. At a threshold value of 2.0 mmHg for UES minimal pressure, dysphagia was diagnosed at 74.7% sensitivity and 60.7% specificity. Lastly, UES relaxation duration of <0.58 seconds had 85.7% sensitivity and 65.3% specificity, and UES resting pressure of <75.0 mmHg had 89.3% sensitivity and 90.7% specificity for identifying dysphagia. Conclusion We present evidence that HRM could be a useful evaluation tool for detecting pharyngeal dysphagia. PMID:29201816

The aim of this study was to describe the presentation of pharyngeal dystonia (PD), which can occur as a focal or segmental dystonia with a primarily pharyngeal involvement for the discussion of treatment methods for controlling consequent symptoms. PD is specific to speech-related tasks. A retrospective medical record review of four patients with PD was performed. All patients were initially misdiagnosed with adductor spasmodic dysphonia and failed standard treatment with botulinum toxin type A (BTX). On laryngoscopy, the patients were discovered to have segmental or focal dystonia primarily affecting the pharyngeal musculature contributing to their vocal manifestations. A novel treatment regimen was designed, which involved directing BTX injections into the muscles involved in spasmodic valving at the oropharyngeal level. After titrating to an optimal dose, all patients showed improvement in their voice and speech with only mild dysphagia. These patients have maintained favorable results with repeat injections at 6- to 12-week intervals. PD, or dystonia with predominant pharyngeal involvement, is a rare entity with vocal manifestations that are not well described. It can be easily mistaken for spasmodic dysphonia. PD is specific to speech-related tasks. A novel method of BTX injections into the involved muscles results in a significant improvement in voice without significant dysphagia.

To determine which objective pressure-impedance measures of pharyngeal swallowing function correlated with clinically assessed severity of oropharyngeal dysphagia (OPD) symptoms. Forty-five children with OPD and 34 control children without OPD were recruited and up to 5 liquid bolus swallows were recorded with a solid-state high-resolution manometry with impedance catheter. Individual measures of pharyngeal and upper esophageal sphincter (UES) function and a swallow risk index composite score were derived for each swallow, and averaged data for patients with OPD were compared with those of control children without OPD. Clinical severity of OPD symptoms and oral feeding competency was based on the validated Dysphagia Disorders Survey and Functional Oral Intake Scale. Those objective measures that were markers of UES relaxation, UES opening, and pharyngeal flow resistance differentiated patients with and without OPD symptoms. Patients demonstrating abnormally high pharyngeal intrabolus pressures and high UES resistance, markers of outflow obstruction, were most likely to have signs and symptoms of overt Dysphagia Disorders Survey (OR 9.24, P = .05, and 9.7, P = .016, respectively). Pharyngeal motor patterns can be recorded in children by the use of HRIM and pharyngeal function can be defined objectively with the use of pressure-impedance measures. Objective measurements suggest that pharyngeal dysfunction is common in children with clinical signs of OPD. A key finding of this study was evidence of markers of restricted UES opening.

Objective To investigate improved dysphagia after the decannulation of a tracheostomy in patients with brain injuries. Methods The subjects of this study are patients with brain injuries who were admitted to the Department of Rehabilitation Medicine in Myongji Hospital and who underwent a decannulation between 2012 and 2014. A video fluoroscopic swallowing study (VFSS) was performed in order to investigate whether the patients' dysphagia had improved. We measured the following 5 parameters: laryngeal elevation, pharyngeal transit time, post-swallow pharyngeal remnant, upper esophageal width, and semisolid aspiration. We analyzed the patients' results from VFSS performed one month before and one month after decannulation. All VFSS images were recorded using a camcorder running at 30 frames per second. An AutoCAD 2D screen was used to measure laryngeal elevation, post-swallow pharyngeal remnant, and upper esophageal width. Results In this study, a number of dysphagia symptoms improved after decannulation. Laryngeal elevation, pharyngeal transit time, and semisolid aspiration showed no statistically significant differences (p>0.05), however after decannulation, the post-swallow pharyngeal remnant (pre 37.41%±24.80%, post 21.02%±11.75%; p<0.001) and upper esophageal width (pre 3.57±1.93 mm, post 4.53±2.05 mm; p<0.001) showed statistically significant differences. Conclusion When decannulation is performed on patients with brain injuries who do not require a ventilator and who are able to independently excrete sputum, improved esophageal dysphagia can be expected.

Pharyngeal electrical stimulation device for the treatment of neurogenic dysphagia: technology update.

PubMed

Restivo, Domenico A; Hamdy, Shaheen

2018-01-01

Neurogenic dysphagia (ND) can occur in patients with nervous system diseases of varying etiologies. Moreover, recovery from ND is not guaranteed. The therapeutic approaches for oropharyngeal ND have drastically changed over the last decade, mainly due to a better knowledge of the neurophysiology of swallowing along with the progress of neuroimaging and neurophysiological studies. For this reason, it is a priority to develop a treatment that is repeatable, safe, and can be carried out at the bedside as well as for outpatients. Pharyngeal electrical stimulation (PES) is a novel rehabilitation treatment for ND. PES is carried out via location-specific intraluminal catheters that are introduced transnasally and enable clinicians to stimulate the pharynx directly. This technique has demonstrated increasingly promising evidence in improving swallowing performance in patients with ND associated with stroke and multiple sclerosis, probably by increasing the corticobulbar excitability and inducing cortical reorganization of swallowing motor cortex. In this article, we update the reader as to both the physiologic background and past and current studies of PES in an effort to highlight the clinical progress of this important technique.

Prospective study. To prospectively assess the incidence of dysphagia and to present the serial changes of each finding in the videofluoroscopic swallow study (VFSS) after anterior cervical discectomy and fusion (ACDF). The reported incidence of dysphagia after ACDF has varied widely, and the serial changes of dysphagia using VFSS have not been clearly determined yet. Data of 47 patients preoperatively and at 1 week and 1 month postoperatively were used for the analyses. The Bazaz dysphagia score and VFSS were checked preoperatively and at 1 week and 1 month postoperatively. The presence of aspiration or penetration, amount of vallecular and pyriform sinus residues, functional dysphagia scale, temporal parameters of oral transit time, pharyngeal transit time, and pharyngeal delay time (PDT) were evaluated from the VFSS data. Incidences of dysphagia measured by the Bazaz dysphagia score were 83.0% at 1 week and 59.6% at 1 month after ACDF. Although the incidence of aspiration was 4.3% and the incidence of penetration was 36.2% at 1 week and 25.5% at 1 month after surgery, none of the patients had aspiration pneumonia. The number of patients with vallecular and pyriform sinus residues significantly increased after ACDF. Further, there were no statistically significant changes at all time points in terms of oral transit time, pharyngeal transit time, and pharyngeal delay time. Dysphagia is common until 1 month after ACDF. Although the incidence of aspiration or penetration in VFSS after ACDF was high, no patient had aspiration pneumonia, which may be because of the intact neurological swallowing mechanism. The typical pattern of dysphagia after ACDF included vallecular and pyriform sinuses filled with postswallow residue, which may result from soft tissue edema and weak constriction of pharyngeal muscles after ACDF.

Quantitative, reliable measures of swallowing physiology can be made from an modified barium swallowing study. These quantitative measures have not been previously employed to study large dysphagic patient populations. The present retrospective study of 139 consecutive patients with dysphagia seen in a university tertiary voice and swallowing clinic sought to use objective measures of swallowing physiology to (1) quantify the most prevalent deficits seen in the patient population, (2) identify commonly associated diagnoses and describe the most prevalent swallowing deficits, and (3) determine any correlation between objective deficits and Eating Assessment Tool (EAT-10) scores and body mass index. Poor pharyngeal constriction (34.5 %) and airway protection deficits (65.5 %) were the most common swallowing abnormalities. Reflux-related dysphagia (36 %), nonspecific pharyngeal dysphagia (24 %), Parkinson disease (16 %), esophageal abnormality (13 %), and brain insult (10 %) were the most common diagnoses. Poor pharyngeal constriction was significantly associated with an esophageal motility abnormality (p < 0.001) and central neurologic insult. In general, dysphagia symptoms as determined by the EAT-10 did not correlate with swallowing function abnormalities. This preliminary study indicates that reflux disease is common in patients with dysphagia and that associated esophageal abnormalities are common in dysphagic populations and may be associated with specific pharyngeal swallowing abnormalities. However, symptom scores from the EAT-10 did not correspond to swallowing pathophysiology.

Goals Computational Analysis of Swallowing Mechanics is a method that utilizes multivariate shape change analysis to uncover covariant elements of pharyngeal swallowing mechanics associated with impairment using videofluoroscopic swallowing studies. The goals of this preliminary study were to (1) characterize swallowing mechanics underlying stroke related dysphagia, (2) decipher the impact of left and right hemispheric stroke on pharyngeal swallowing mechanics, and (3) determine pharyngeal swallowing mechanics associated with penetration-aspiration status. Materials and Methods Videofluoroscopic swallowing studies of 18 dysphagic patients with hemispheric infarcts and age and gender matched controls were selected from well-controlled data sets. Patient data including laterality, and penetration-aspiration status was collected. Coordinates mapping muscle group action during swallowing were collected from videos. Multivariate morphometric analyses of coordinates associated with stroke, affected hemisphere, and penetration-aspiration status were performed. Findings Pharyngeal swallowing mechanics differed significantly in the following comparisons: stroke vs. controls (D=2.19, p<.0001); right hemispheric stroke vs. controls (D=3.64, p<.0001); left hemispheric stroke vs. controls (D=2.06, p<.0001); right hemispheric stroke vs. left hemispheric stroke (D=2.89, p<.0001); and penetration-aspiration vs. within normal limits (D=2.25, p<.0001). Differences in pharyngeal swallowing mechanics associated with each comparison were visualized using eigenvectors. Conclusion While current literature focuses on timing changes in stroke-related dysphagia, this data suggests that mechanical changes are also functionally important. Pharyngeal swallowing mechanics differed by affected hemisphere and penetration-aspiration status. Computational Analysis of Swallowing Mechanics can be used to identify patient specific swallowing impairment associated with stroke injury that could help

Postlaryngectomy, pharyngeal weakness, and pharyngoesophageal junction (PEJ) restriction are the candidate mechanisms of dysphagia. The aims were, in laryngectomees, whether (1) hypopharyngeal propulsion is reduced and/or PEJ resistance is increased, (2) dilatation improves dysphagia, and (3) whether symptomatic improvement correlates with reduced PEJ resistance. Multidisciplinary cross-sectional study. Tertiary academic hospital. Swallow biomechanics were assessed in 30 laryngectomees. Patients were stratified into severe dysphagia (Sydney Swallow Questionnaire >500) and mild/nil dysphagia (Sydney Swallow Questionnaire ≤500). Average hypopharyngeal peak (contractile) pressure (hPP) and hypopharyngeal intrabolus pressure (hIBP) were measured from high-resolution manometry with concurrent videofluoroscopy based on barium swallows (2.5 and 10 mL). In consecutive 5 patients, measurements were repeated after dilatation. Dysphagia was reported by 87%, and 57% had severe and 43% had mild/nil dysphagia. hIBP increased with larger bolus volumes (P < .0001), while hPP stayed stable and PEJ diameter plateaued at 9 mm. Laryngectomees had lower hPP (110 ± 14 vs 170 ± 15 mm Hg; P = .0162) and higher hIBP (29 ± 5 vs 6 ± 5 mm Hg; P = .156) than controls. There were no differences in hPP between patient groups. However, hIBP was higher in severe than in mild/nil dysphagia (41 ± 10 vs 13 ± 3 mm Hg; P = .02). Predilation hIBP (R(2) = 0.97) and its decrement postdilatation (R(2) = 0.98) well predicted symptomatic improvement. PEJ resistance correlates better with dysphagia severity than peak pharyngeal pressure and is more sensitive to bolus sizes than PEJ diameter. Both baseline PEJ resistance and its decrement following dilatation are strong predictors of treatment outcome. PEJ resistance is vital to detect, as it is reversible and can predict the response to dilatation regimens. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

Pharyngeal phase is a central hub of swallowing in which food bolus pass through from the oral cavity to the esophageal. Proper understanding of the muscular activities in the pharyngeal phase is useful for assessing swallowing function and the occurrence of dysphagia in humans. In this study, high-density (HD) surface electromyography (sEMG) was used to study the muscular activities in the pharyngeal phase during swallowing tasks involving three healthy male subjects. The root mean square (RMS) of the HD sEMG data was computed by using a series of segmented windows as myoelectrical energy. And the RMS of each window covering all channels (16×5) formed a matrix. During the pharyngeal phase of swallowing, three of the matrixes were chosen and normalized to obtain the HD energy maps and the statistical parameter. The maps across different viscosity levels offered the energy distribution which showed the muscular activities of the left and right sides of the front neck muscles. In addition, the normalized average RMS (NARE) across different viscosity levels revealed a left-right significant correlation (r=0.868±0.629, p<;0.01) quantitatively, while it showed even stronger correlation when swallowing water. This pilot study suggests that HD sEMG would be a potential tool to evaluate muscular activities in pharyngeal phase during normal swallowing. Also, it might provide useful information for dysphagia diagnosis.

Multivariate morphometric analyses of coordinates associated with stroke, affected hemisphere, and penetration-aspiration status were performed. Pharyngeal swallowing mechanics differed significantly in the following comparisons: stroke versus controls (D = 2.19, P < .0001), right hemispheric stroke versus controls (D = 3.64, P < .0001), left hemispheric stroke versus controls (D = 2.06, P < .0001), right hemispheric stroke versus left hemispheric stroke (D = 2.89, P < .0001), and penetration-aspiration versus within normal limits (D = 2.25, P < .0001). Differences in pharyngeal swallowing mechanics associated with each comparison were visualized using eigenvectors. Whereas current literature focuses on timing changes in stroke-related dysphagia, these data suggest that mechanical changes are also functionally important.

To evaluate the risk and outcome of pharyngoesophageal stenosis in patients who complained of dysphagia following radiation for head and neck cancer. Retrospective study. Veterans Administration hospital. Patients who complained of persistent dysphagia following radiation alone or combined with surgery or chemotherapy for head and neck cancer. Patients were selected if they were cancer free at the time of the swallowing study. All patients had modified barium swallow (MBS) and an endoscopic examination for initial evaluation of their dysphagia. Traditional barium swallow was requested when there was a suspicion of pharyngoesophageal stenosis on MBS. Two hundred twenty-two patients underwent MBS for evaluation of dysphagia posttreatment. Traditional barium swallow confirmed the diagnosis of pharyngeal (n = 2) or esophageal (n = 14) stenosis in 16 patients. Eight patients had esophageal stenosis on endoscopic examination. All patients underwent dilatation for relief of their dysphagia. The number of dilatations performed was, respectively, one in 12 patients, two in 4 patients, three in 3 patients, four in 3 patients, five in one patient, and six in one patient. Pharyngeal and/or cervical esophageal stenosis may be the cause of dysphagia following radiation for head and neck cancer. Esophageal dilatations often offer temporary relief of the dysphagia.

Pharyngeal pressure-flow analysis (PFA) of high resolution impedance-manometry (HRIM) with calculation of the swallow risk index (SRI) can quantify swallow dysfunction predisposing to aspiration. We explored the potential use of artificial neural networks (ANN) to model the relationship between PFA swallow metrics and aspiration and to predict swallow dysfunction. Two hundred consecutive dysphagia patients referred for videofluoroscopy and HRIM were assessed. Presence of aspiration was scored and PFA software derived 13 metrics and the SRI. An ANN was created and optimized over training cycles to achieve optimal classification accuracy for matching inputs (PFA metrics) to output (presence of aspiration on videofluoroscopy). Application of the ANN returned a value between 0.00 and 1.00 reflecting the degree of swallow dysfunction. Twenty one patients were excluded due to insufficient number of swallows (<4). Of 179, 58 aspirated and 27 had aspiration pneumonia history. The SRI was higher in aspirators (aspiration 24 [9, 41] vs no aspiration 7 [2, 18], p < 0.001) and patients with pneumonia (pneumonia 27 [5, 42] vs no pneumonia 8 [3, 24], p < 0.05). The ANN Predicted Risk was higher in aspirators (aspiration 0.57 [0.38, 0.82] vs no aspiration 0.13 [0.4, 0.25], p < 0.001) and in patients with pneumonia (pneumonia 0.46 [0.18, 0.60] vs no pneumonia 0.18 [0.6, 0.49], p < 0.01). Prognostic value of the ANN was superior to the SRI. In a heterogeneous cohort of dysphagia patients, PFA with ANN modeling offers enhanced detection of clinically significant swallowing dysfunction, probably more accurately reflecting the complex interplay of swallow characteristics that causes aspiration. © 2016 John Wiley & Sons Ltd.

Dysphagia can result from a variety of causes, including central nervous and peripheral nervous system, myogenic, and structural disorders. A 76-year-old man underwent anterior cervical disketomy and fusion 10 years ago, with progressive dysphagia noted 2 years ago. Endoscopy showed an oropharyngeal tumor, and lateral plain film evaluation of the neck revealed a cervical plate extrusion. Removal of the instrumentation and tumor with primary closure of the pharyngeal perforation was performed, and dysphagia was resolved postoperatively. We report the case of an unusual presentation in the pharynx. We should not neglect this rare diagnosis, because it can progress to a life-threatening outcome.

Dysphagia is common sequelae of chemical ingestion injury, resulting from damage to critical swallowing structures. From a speech-language pathology perspective, this study outlines the physiological deficits in 2 individuals with severe injury (1 woman, acid; 1 man, alkali) and the pattern of dysphagia rehabilitation and recovery. A retrospective chart review of clinical and instrumental assessments was conducted to examine swallow characteristics and speech-language pathology management (compensatory and rehabilitation strategies) at multiple time points. Chemical ingestion injury resulted in severe pharyngeal dysphagia for both participants, warranting speech-language pathology management. Dysphagia was characterized by poor base of tongue mobility and reduced laryngeal excursion. Decreased airway patency and protection, secondary to mucosal sloughing, widespread edema, and structural deficits necessitated tracheostomy. Recovery was complicated by physical alterations of pharyngeal and laryngeal structures (e.g., interarytenoid adhesions) and esophageal strictures. Participant 1 was discharged (Day 135) consuming a texture-modified diet; Participant 2 remained nil by mouth (Day 329). Dysphagia recovery subsequent to chemical ingestion is protracted and complex. Clinical outcomes may be improved through individualized and intensive rehabilitation by speech-language pathologists.

Dysphagia, which can result in aspiration pneumonia and death, is a well-known problem in patients with dementia and Parkinson's disease. There are few studies on dysphagia in patients with dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD), especially studies objectively documenting the type of swallowing dysfunction. The aim of this study was therefore to investigate the prevalence, and define the actual swallowing dysfunction according to a videofluoroscopic swallowing examination (VFSE) in patients with DLB and PDD. Eighty-two consecutive patients with DLB or PDD in a clinical follow-up program were asked about symptoms of dysphagia. Those experiencing dysphagia were examined with VFSE. Prevalence and type of swallowing dysfunction was recorded. Twenty-six patients (32%) reported symptoms of dysphagia such as swallowing difficulties or coughing. Twenty-four (92%) of these had a documented swallowing dysfunction on VFSE. Eighty-eight percent suffered from pharyngeal dysfunction. Almost all DLB or PDD patients with subjective signs of dysphagia had pathologic results on VFSE, the majority of pharyngeal type. This type of dysphagia has not been reported in DLB before. The results have clinical implications and highlight the importance of asking for and examining swallowing function to prevent complications such as aspiration.

2013-06-01

Automated impedance manometry (AIM) analysis measures swallow variables defining bolus timing, pressure, contractile vigour, and bolus presence, which are combined to derive a swallow risk index (SRI) correlating with aspiration. In a heterogeneous cohort of dysphagia patients, we assessed the impact of bolus volume and viscosity on AIM variables. We studied 40 patients (average age = 46 years). Swallowing of boluses was recorded with manometry, impedance, and videofluoroscopy. AIMplot software was used to derive functional variables: peak pressure (PeakP), pressure at nadir impedance (PNadImp), time from nadir impedance to peak pressure (TNadImp-PeakP), the interval of impedance drop in the distal pharynx (flow interval, FI), upper oesophageal sphincter (UES) relaxation interval (UES RI), nadir UES pressure (Nad UESP), UES intrabolus pressure (UES IBP), and UES resistance. The SRI was derived using the formula SRI = (FI * PNadImp)/(PeakP * (TNadImp-PeakP + 1)) * 100. A total of 173 liquid, 44 semisolid, and 33 solid boluses were analysed. The SRI was elevated in relation to aspiration. PeakP increased with volume. SRI was not significantly altered by bolus volume. PNadImp, UES IBP, and UES resistance increased with viscosity. SRI was lower with increased viscosity. In patients with dysphagia, the SRI is elevated in relation to aspiration, reduced by bolus viscosity, and not affected by bolus volume. These data provide evidence that pharyngeal AIM analysis may have clinical utility for assessing deglutitive aspiration risk to liquid boluses.

To investigate whether disclosed symptoms (coughing, choking and throat clearing) can be used as early predictors of swallowing disorders in non-hospitalized elderly population. In addition, to determine the presence of early findings of swallowing disorders through fiber optic endoscopic evaluation of swallowing (FEES). One hundred subjects older than 60 years were recruited from local community social meetings for seniors, they fulfilled inclusion criteria, and were given an oral interview and underwent FEES, with findings classified as: (1) saliva stasis; (2) pharyngeal residue; (3) penetration; (4) aspiration; (5) laryngeal sensitivity. Twenty-one percent of subjects declared previous choking, 10% coughing, and 7% throat clearing, 39% had pharyngeal residue; 6% saliva stasis; 9% penetration; 2% aspiration; and 92% laryngeal sensitivity present. Thirty-three percent showed pharyngeal residue without saliva stasis, while only 6% showed positivity for both (p = 0.003). Our data suggest that health care professionals should be aware that among an apparently healthy population, some subjects may have swallowing disorders without clinical complaints and that a nasolaryngoscopy exam may not be enough to predict dysphagia. We suggest that FEES should be performed to look for surrogate of dysphagia such as pharyngeal residue, laryngeal penetration, and aspiration.

Botulinum toxin treatment for oropharyngeal dysphagia in patients with stroke.

In a previous pilot study, we demonstrated that a single injection of botulinum toxin A (BTX-A) in the cricopharyngeus muscle is effective in patients with neurologic dysphagia with upper esophageal sphincter (UES) opening dysfunction and presence of some pharyngeal contraction (>25 mmHg). The aim of this study was to confirm the long-lasting efficacy of this procedure after stroke. We prospectively studied 23 patients with stroke for at least 6 months before administration of a BTX-A injection. Baseline diagnosis of UES opening dysfunction and presence of some pharyngeal contraction were assessed by videofluoroscopy (VFS) and esophageal manometry (EM). Clinical and VFS follow-up was made at 3 weeks and 3, 6, and 12 months postinjection. Eighteen patients (78%) were fed by gastrostomy tube prior to treatment. Videofluoroscopy showed UES relaxation impairment, residue in pyriform sinuses, and aspiration in all cases. After BTX-A, the number of patients with aspiration and pharyngeal residue decreased to 52% and 70%, respectively (p < 0.05 for both); residue was severe in only 4%. Esophageal manometry showed a mean pharyngeal amplitude 66.8 mmHg (range: 25-120 mmHg). We observed a significant improvement in feeding mode during follow-up: after 3 months, 70% of patients were eating exclusively by mouth. Lower residual pressure and minor pharyngeal delay time at baseline were all predictive factors for treatment effectiveness. A single injection of BTX-A is efficacious for a period of at least 12 months in improving oropharyngeal dysphagia in stroke patients with UES opening dysfunction and some pharyngeal contraction (>25 mmHg). © 2013 John Wiley & Sons Ltd.

We examined measures of oral and pharyngeal residues from scintigraphic studies and estimates/observations from videofluorographic (modified barium swallow) studies taken on the same day but not concurrently in 16 dysphagic patients of varying etiologies presenting with oral and/or pharyngeal dysphagia. Oral and pharyngeal residuals following the swallow were quantified scintigraphically and were then compared with measures of residuals obtained from the modified barium swallow. Estimates of oral and pharyngeal residues from the modified barium swallows were generated by a trained observer who was blinded to the scintigraphic data. Positive and significant Spearman correlations between oral and pharyngeal residue measures from scintigraphy and observations of oral and pharyngeal residues from modified barium swallows were found. This supports the validity of observations of oral and pharyngeal residues in clinical studies. Limitations of these observations are discussed. PMID:16362511

Patients who have an ischemic stroke are at high risk of swallowing disorders. Aspiration due to swallowing disorders, specifically delayed trigger of the pharyngeal stage of swallowing, predisposes such patients to pneumonia. In the present study, we evaluated swallowing reflex in a rat model of transient middle cerebral artery occlusion (tMCAO), which is one of the most common experimental animal models of cerebral ischemia, in order to develop a novel animal model of dysphagia following ischemic stroke. A swallowing reflex was elicited by a 10-s infusion of distilled water (DW) to the pharyngolaryngeal region in the tMCAO rat model. Swallowing reflex was estimated using the electromyographic activity of the mylohyoid muscle from 1 to 3 weeks after surgery. Two weeks after tMCAO, the number of swallows significantly decreased and the onset latency of the first swallow was prolonged compared with that of the sham group. The number of swallows in rats significantly increased by infusions of 10 mM citric acid and 0.6 μM capsaicin to the pharyngolaryngeal region compared with the number from infusion of DW. It has been reported that sensory stimulation of the pharyngolaryngeal region with citric acid, capsaicin, and L-menthol ameliorates hypofunction of pharyngeal-stage swallowing in dysphagia patients. Therefore, the tMCAO rat model may show some of the symptoms of pharyngeal-stage swallowing disorders, similar to those in patients with ischemic stroke. This rat tMCAO model has the potential to become a novel animal model of dysphagia following stroke that is useful for development of therapeutic methods and drugs.

Feeding and swallowing disorders in the pediatric population are becoming more common, particularly in infants born prematurely and in children with chronic medical conditions. The normal swallowing mechanism is divided into 4 stages: the preparatory, the oral, the pharyngeal, and the esophageal phases. Feeding disorders have multiple causes: medical, nutritional, behavioral, psychological, and environmental factors can all contribute. Pathologic conditions involving any of the anatomic sites associated with the phases of swallowing can negatively impact the coordination of these phases and lead to symptoms of dysphagia and feeding intolerance.

[Dysphagia or dysphagias during neuroleptic medication?].

Chaumartin, N; Monville, M; Lachaux, B

Dysphagia is a common symptom in the general population, and even more among psychiatric patients, but rarely seen as a sign of seriousness. It is a cause of death by suffocation, and more or less serious complications, and therefore should be diagnosed and treated. Among psychiatric patients, organic and iatrogenic aetiologies, as well as risk factors are identified, which worsen this symptom when associated. It is now accepted that neuroleptics can aggravate or cause dysphagia. They act by several pathophysiological ways on the different components of swallowing, which can be identified by dynamic tests in the upper aerodigestive tract endoscopy. This symptom is rarely reported by patients and often underestimated by caregivers. The frequency of swallowing disorders is not known. Dysphagia is a cause of complications and an increase in mortality rates among psychiatric patients. It has also been found that the average number of psychotropic drugs in patients who die by cafe coronary is significantly higher than in other patients. There are several phases in swallowing: oral, pharyngeal, and oesophageal. Swallowing disorders can affect each of these phases, or several at once: (a) Extrapyramidal syndrome: dysphagia is present in drug induced Parkinson's syndromes, but prevalence is not known. It is most often associated with another symptom of the extrapyramidal syndrome, but can also be isolated, making its diagnosis more difficult. Dysphagia is due to a slowing down in the oral and pharyngeal reflex, called bradykinesia; (b) Tardive dyskinesia: the oro-pharyngo-oesophageal dyskinesia is the most common type. Oesophageal dyskinesia causes asynchronous and random movements of the oesophagus, resulting in dysphagia. It appears mostly beyond 3 months of treatment with neuroleptics; (c) Acute laryngeal or oesophageal dystonia, associated or not with orofacial dystonia, is characterised by an impairment in the oesophageal muscle contraction and a hypertonia of the

Dysphagia in Parkinson's Disease.

More than 80 % of patients with Parkinson's disease (PD) develop dysphagia during the course of their disease. Swallowing impairment reduces quality of life, complicates medication intake and leads to malnutrition and aspiration pneumonia, which is a major cause of death in PD. Although the underlying pathophysiology is poorly understood, it has been shown that dopaminergic and non-dopaminergic mechanisms are involved in the development of dysphagia in PD. Clinical assessment of dysphagia in PD patients is challenging and often delivers unreliable results. A modified water test assessing maximum swallowing volume is recommended to uncover oropharyngeal dysphagia in PD. PD-specific questionnaires may also be useful to identify patients at risk for swallowing impairment. Fiberoptic endoscopic evaluation of swallowing and videofluoroscopic swallowing study are both considered to be the gold standard for evaluation of PD-related dysphagia. In addition, high-resolution manometry may be a helpful tool. These instrumental methods allow a reliable detection of aspiration events. Furthermore, typical patterns of impairment during the oral, pharyngeal and/or esophageal swallowing phase of PD patients can be identified. Therapy of dysphagia in PD consists of pharmacological interventions and swallowing treatment by speech and language therapists (SLTs). Fluctuating dysphagia with deterioration during the off-state should be treated by optimizing dopaminergic medication. The methods used during swallowing treatment by SLTs shall be selected according to the individual dysphagia pattern of each PD patient. A promising novel method is an intensive training of expiratory muscle strength. Deep brain stimulation does not seem to have a clinical relevant effect on swallowing function in PD. The goal of this review is giving an overview on current stages of epidemiology, pathophysiology, diagnosis, and treatment of PD-associated dysphagia, which might be helpful for neurologists

Purpose: Intensification of radiotherapy and chemotherapy for head-and-neck cancer may lead to increased rates of dysphagia. Dosimetric predictors of objective findings of long-term dysphagia were sought. Methods and Materials: From an institutional database, 83 patients were identified who underwent definitive intensity-modulated radiotherapy for squamous cell carcinoma of the head and neck, after exclusion of those who were treated for a second or recurrent head-and-neck primary lesion, had locoregional recurrence at any time, had less than 12 months of follow-up, or had postoperative radiotherapy. Dosimetric parameters were analyzed relative to three objective endpoints as a surrogate for severe long-term dysphagia: percutaneousmore » endoscopic gastrostomy (PEG) tube dependence at 12 months, aspiration on modified barium swallow, or pharyngoesophageal stricture requiring dilation. Results: Mean dose greater than 41 Gy and volume receiving 60 Gy (V{sub 60}) greater than 24% to the larynx were significantly associated with PEG tube dependence and aspiration. V{sub 60} greater than 12% to the inferior pharyngeal constrictor was also significantly associated with increased PEG tube dependence and aspiration. V{sub 65} greater than 33% to the superior pharyngeal constrictor or greater than 75% to the middle pharyngeal constrictor was associated with pharyngoesophageal stricture requiring dilation. Conclusions: Doses to the larynx and pharyngeal constrictors predicted long-term swallowing complications, even when controlled for other clinical factors. The addition of these structures to intensity-modulated radiotherapy optimization may reduce the incidence of dysphagia, although cautious clinical validation is necessary.« less

Wilson's disease is an autosomal recessive disorder of abnormal copper metabolism. Although dysphagia is a common complaint of patients with Wilson's disease and pneumonia is an important cause of death in these patients, management of swallowing function has rarely been reported in the context of Wilson's disease. Hence, we report a case of Wilson's disease presenting with dysphagia. A 33-year-old man visited our hospital with a complaint of difficulty in swallowing, since about last 7 years and which had worsened since the last 2-3 months. He was diagnosed with Wilson's disease about 13 years ago. On the initial VFSS, reduced hyoid bone movement, impaired epiglottic movement and moderate amount of residue in the valleculae during the pharyngeal phase were noted. After 10 sessions of neuromuscular electrical stimulation for 1 hour per day, decreased amount of residue was observed in the valleculae during the pharyngeal phase on the follow-up VFSS.

Dysphagia and sialorrhea in patients with Parkinson's disease are both automatically accepted as dependent on this neurological disease. The aim were to establish if these two complaints are a consequence or associated manifestations of Parkinson's disease. Two Parkinson's diseases groups from the same outpatients' population were studied. Patients in the first group, with dysphagia, were studied by videofluoroscopy. The second, with sialorrhea, were studied by the scintigraphic method, Videofluoroscopic examination of the oral, pharyngeal and esophageal phases of swallowing showed that 94% of Parkinson's diseases patients present, structural causes, not related to Parkinson's diseases, able to produce or intensify the observed disphagia. The scintigraphic examination of Parkinson's diseases patients with sialorrhea showed that there is no increase of serous saliva production. Nevertheless, showed a significantly higher velocity of saliva excretion in the Parkinson's diseases patients. Dysphagia can be due to the muscular rigidity often present in the Parkinson's diseases patient, or more usually by non Parkinson's disease associated causes. In Parkinson's diseases patients, sialorrhea is produced by saliva retention. Nevertheless, sialorrhea can produce discomfort in swallowing, although without a formal complaint of dysphagia. In this case, subclinical dysphagia must be considered. Sialorrhea is indicative of dysphagia or at least of subclinical dysphagia. As final conclusion, Parkinson's diseases can be an isolated cause of dysphagia and/or sialorrhea, but frequently, a factor unrelated to Parkinson's diseases is the main cause of or at least aggravates the dysphagia.

Dysphagia is common in dependent older adults. Thus, a method of evaluating eating and swallowing functions that can be used to diagnose and manage dysphagia in a simple and robust manner is required. In 2002, the Mann Assessment of Swallowing Ability (MASA) was introduced to identify dysphagia in acute-stage stroke patients. As the MASA enables easy screening, it might also be applicable to dependent older adults if appropriate MASA cut-off values and the most useful assessment items could be determined. In the present study, we attempted to determine suitable MASA cut-off values, and the most useful assessment items for predicting aspiration and pharyngeal retention in dependent older adults. Using the MASA, we evaluated the eating and swallowing functions of 50 dependent older adults with dysphagia. All of the patients also underwent videoendoscopic-based swallowing evaluations to detect aspiration and pharyngeal retention. The participants' characteristics and the utility of each assessment item were compared between various groups. Using the patients' videoendoscopic findings as a reference, receiver operating characteristic curve analysis was carried out to determine appropriate cut-off values for predicting aspiration and pharyngeal retention in dependent older adults. The optimal MASA cut-off values for predicting aspiration and pharyngeal retention were 122 points and 151 points, respectively. A total of 17 of the 24 clinical items assessed by the MASA were found to be associated with aspiration in dependent older adults. The MASA is a useful screening tool for evaluating eating and swallowing functions in dependent older adults. Geriatr Gerontol Int 2017; 17: 561-567. © 2016 Japan Geriatrics Society.

Spinocerebellar ataxia type 6 (SCA6), an autosomal dominant triplet repeat disease, predominantly affects the cerebellum with a late onset and generally good prognosis. Dysphagia is commonly associated with the outcomes of neurodegenerative diseases such as SCA6. Although the characteristics of dysphagia have been rarely reported in SCA6, our previous study indicated that dysphagia is generally milder in SCA6 than in SCA3, another inherited ataxia with multisystem involvement. However, abnormalities in the pharyngeal phase in SCA6 were indistinguishable from those in SCA3, with no explainable reason. To determine the reason, we repeatedly performed videofluoroscopic examinations (VF) in 14 patients with SCA6. The results showed that the gross progression of dysphagia was apparently slow, but four patients had progressive dysphagia at an early disease stage; dysphagia began within 10 years from the onset of ataxia and rapidly progressed. A common clinical feature of the four patients was a significantly older age at the onset of ataxia (74.0 vs. 60.3 years), associated with significantly shorter triplet repeats. This finding surprisingly indicated that patients who had shorter repeats and thereby later onset and potentially better prognoses were at risk for dysphagia-associated problems. Ischemic changes, homozygous mutation, and diabetes mellitus as well as aging might have contributed to the observed progressive dysphagia. We found that conventionally monitored somatosensory evoked potentials at least partly reflected progressive dysphagia. Despite the small study group, our findings suggest that clinicians should carefully monitor dysphagia in patients with SCA6 who are older at disease onset (>60 years).

Clinical case series and risk factor analysis of dysphagia after occipitospinal fusion (OSF). The aim of this study was to develop new criteria to avoid postoperative dysphagia by analyzing the relationship among the craniocervical alignment, the oropharyngeal space, and the incidence of dysphagia after OSF. Craniocervical malalignment after OSF is considered to be one of the primary triggers of postoperative dysphagia. However, ideal craniocervical alignment has not been confirmed. Thirty-eight patients were included. We measured the O-C2 angle (O-C2A) and the pharyngeal inlet angle (PIA) on the lateral cervical radiogram at follow-up. PIA is defined as the angle between McGregor's line and the line that links the center of the C1 anterior arch and the apex of cervical sagittal curvature. The impact of these two parameters on the diameter of pharyngeal airway space (PAS) and the incidence of the dysphagia were analyzed. Six of 38 cases (15.8%) exhibited the dysphagia. A multiple regression analysis showed that PIA was significantly correlated with PAS (β = 0.714, P = 0.005). Receiver-operating characteristic curves showed that PIA had a high accuracy as a predictor of the dysphagia with an AUC (area under the curve) of 0.90. Cases with a PIA less than 90 degrees showed significantly higher incidence of dysphagia (31.6%) than those with a 90 or more degrees of PIA (0.0%) (P = 0.008). Our results indicated that PIA had the high possibility to predict postoperative dysphagia by OSF with the condition of PIA <90°. Based on these results, we defined "Swallowing-line (S-line)" for the reference of 90° of PIA. S-line (-) is defined as PIA <90°, where the apex of cervical lordosis protruded anterior to the "S-line," which should indicate the patient is at a risk of postoperative dysphagia. 4.

To assess the jaw-opening force test (JOFT) for dysphagia screening. Criterion standard. University dental hospital. Patients complaining of dysphagia (N=95) and with symptoms of dysphagia with chronic underlying causes (mean age ± SD, 79.3±9.61y; range, 50-94y; men: n=49; mean age ± SD, 77.03±9.81y; range, 50-94y; women: n=46; mean age ± SD, 75.42±9.73y; range, 51-93y) admitted for treatment between May 2011 and December 2012 were included. None. All patients were administered the JOFT and underwent fiberoptic endoscopic evaluation of swallowing (FEES). The mean jaw-opening strength was compared with aspiration (ASP) and pharyngeal residue observations of the FEES, which was used as the criterion standard. A receiver operating characteristic (ROC) curve analysis was performed. Forces of ≤3.2kg for men and ≤4kg for women were appropriate cutoff values for predicting ASP with a sensitivity and specificity of .57 and .79 for men and .93 and .52 for women, respectively. Based on the ROC analyses for predicting pharyngeal residue, forces of ≤5.3kg in men and ≤3.9kg in women were appropriate cutoff values, with a sensitivity and specificity of .80 and .88 for men and .83 and .81 for women, respectively. The JOFT could be a useful screening tool for predicting pharyngeal residue and could provide useful information to aid in the referral of patients for further diagnostic imaging testing. However, given its low sensitivity to ASP the JOFT should be paired with other screening tests that predict ASP. Copyright © 2014 American Congress of Rehabilitation Medicine.

Aims: In patients with inflammatory myopathy and dysphagia, our aims were to determine: (1) the diagnostic utility of clinical and laboratory indicators; (2) the biomechanical properties of the pharyngo-oesophageal segment; (3) the usefulness of pharyngeal videomanometry in distinguishing neuropathic from myopathic dysphagia; and (4) clinical outcome. Methods: Clinical, laboratory, and videomanometric assessment was performed in 13 patients with myositis and dysphagia, in 17 disease controls with dysphagia (due to proven CNS disease), and in 22 healthy age matched controls. The diagnostic accuracy of creatine kinase (CPK), erythrocyte sedimentation rate, antinuclear antibody, and electromyography (EMG) were compared with the gold standard muscle biopsy. The biomechanical properties of the pharyngo-oesophageal segment were assessed by videomanometry. Results: Mean time from dysphagia onset to the diagnosis of myositis was 55 months (range 1–180). One third had no extrapharyngeal muscle weakness; 25% had normal CPK, and EMG was unhelpful in 28%. Compared with neurogenic controls, myositis patients had more prevalent cricopharyngeal restrictive disorders (69% v 14%; p=0.0003), reduced upper oesophageal sphincter (UOS) opening (p=0.01), and elevated hypopharyngeal intrabolus pressures (p=0.001). Videomanometric features favouring a myopathic over a neuropathic aetiology were: preserved pharyngeal swallow response, complete UOS relaxation, and normal swallow coordination. The 12 month mortality was 31%. Conclusions: The notable lack of supportive clinical signs and significant false negative rates for laboratory tests contribute to the marked delay in diagnosis. The myopathic process is strongly associated with restricted sphincter opening suggesting that cricopharyngeal disruption is a useful adjunct to immunosuppressive therapy. The condition has a poor prognosis. PMID:12631653

The aim of this study was to report the characteristics of dysphagia in children with cerebral palsy (CP), related to gross motor function. Videofluoroscopic swallow study was performed in 29 children with CP, according to the manual of Logemann. Five questions about oromotor dysfunction were answered. Gross motor function level was classified by the Gross Motor Function Classification System Expanded and Revised. The results of the videofluoroscopic swallowing studies showed that reduced lip closure, inadequate bolus formation, residue in the oral cavity, delayed triggering of pharyngeal swallow, reduced larynx elevation, coating on the pharyngeal wall, delayed pharyngeal transit time, multiple swallow, and aspiration were significantly more common in the severe group (Gross Motor Function Classification System Expanded and Revised IV or V). As for aspiration, 50% of the children with severe CP had problems, but only 14.3% of them with moderate (Gross Motor Function Classification System Expanded and Revised III) CP and none of them with mild CP had abnormalities. In addition, five of the seven aspiration cases occurred silently. This study shows that dysphagia is closely related to gross motor function in children with CP. Silent aspiration was observed in the moderate to severe CP groups. Aspiration is an important cause of medical problems such as acute and chronic lung disease, and associated respiratory complications contribute significantly in increasing morbidity and mortality in these patient groups. Therefore, the authors suggest that early dysphagia evaluation including videofluoroscopic swallow study is necessary in managing feeding problems and may prevent chronic aspiration, malnutrition, and infections.

Oropharyngeal dysphagia is a major complaint among older people. Dysphagia may cause two types of complications in these patients: (a) a decrease in the efficacy of deglutition leading to malnutrition and dehydration, (b) a decrease in deglutition safety, leading to tracheobronchial aspiration which results in aspiration pneumonia and can lead to death. Clinical screening methods should be used to identify older people with oropharyngeal dysphagia and to identify those patients who are at risk of aspiration. Videofluoroscopy (VFS) is the gold standard to study the oral and pharyngeal mechanisms of dysphagia in older patients. Up to 30% of older patients with dysphagia present aspiration—half of them without cough, and 45%, oropharyngeal residue; and 55% older patients with dysphagia are at risk of malnutrition. Treatment with dietetic changes in bolus volume and viscosity, as well as rehabilitation procedures can improve deglutition and prevent nutritional and respiratory complications in older patients. Diagnosis and management of oropharyngeal dysphagia need a multidisciplinary approach. PMID:20811545

As both amyotrophic lateral sclerosis (ALS) and Parkinson's disease (PD) exhibit a variety of patterns of dysphagia, appropriate symptomatic treatment is provided after evaluation of swallowing function through videofluoroscopic examination of swallowing. In ALS, disease progression is rapid, therefore, respiratory function, swallowing function and nutritional status should be evaluated regularly. When the oral or pharyngeal stage of swallowing are affected early in dysphagia, adjusting swallowing volume and varying consistency can be beneficial in ALS. When all stages of swallowing are impaired in ALS, such complications as pneumonia, dehydration and malnutrition, are observed. In such patients, it is necessary to consider an alternative to oral dietary intake. In PD, dysphagia is not necessarily associated with severity of parkinsonism and can appear at any time during the course of the disease. Dysphagia in PD can occur at any stage of swallowing and frequently accompanies multiple abnormalities. In particular, aspiration is an important risk factor for pneumonia in PD. The effect of L-dopa treatment for dysphagia is often insufficient; however, this treatment remains the first choice because dysphagia is exacerbated during off state. Rehabilitation for dysphagia in PD has also some effect.

Endoscopic evaluation of swallowing (EES) is not commonly used by gastroenterologists to evaluate swallowing in patients with dysphagia. To use transnasal endoscopy to identify factors predicting successful or failed swallowing of pureed foods in elderly patients with dysphagia. EES of pureed foods was performed by a gastroenterologist using a small-calibre transnasal endoscope. Factors related to successful versus unsuccessful swallowing of pureed foods were analyzed with regard to age, comorbid diseases, swallowing activity, saliva pooling, vallecular residues, pharyngeal residues and airway penetration⁄aspiration. Unsuccessful swallowing was defined in patients who could not eat pureed foods at bedside during hospitalization. Logistic regression analysis was used to identify independent predictors of swallowing of pureed foods. During a six-year period, 458 consecutive patients (mean age 80 years [range 39 to 97 years]) were considered for the study, including 285 (62%) men. Saliva pooling, vallecular residues, pharyngeal residues and penetration⁄aspiration were found in 240 (52%), 73 (16%), 226 (49%) and 232 patients (51%), respectively. Overall, 247 patients (54%) failed to swallow pureed foods. Multivariate logistic regression analysis demonstrated that the presence of pharyngeal residues (OR 6.0) and saliva pooling (OR 4.6) occurred significantly more frequently in patients who failed to swallow pureed foods. Pharyngeal residues and saliva pooling predicted impaired swallowing of pureed foods. Transnasal EES performed by a gastroenterologist provided a unique bedside method of assessing the ability to swallow pureed foods in elderly patients with dysphagia.

Dysphagia is not uncommon after stroke. Dysphagia may delay the functional recovery and substantially affects the quality of life after stroke, mainly if lest untreated. To detect and treat dysphagia as early as possible is critical for patients' recovery after stroke. Electrical stimulation has been reported as a treatment for pharyngeal dysphagia in recent studies, but the therapeutic effects of neuromuscular electrical stimulation (VitalStim®) therapy lacks convincing supporting evidence, needs further clinical investigation. To investigate the effects of neuromuscular electrical stimulation (VitalStim®) and traditional swallowing therapy on recovery of swallowing difficulties after stroke. Randomized controlled trial. University hospital. 135 stroke patients who had a diagnosis of dysphagia at the age between 50-80. 135 subjects were randomly divided into three groups: traditional swallowing therapy (N. = 45), VitalStim® therapy (N. = 45), and VitalStim® therapy plus traditional swallowing therapy (N. = 45). The traditional swallowing therapy included basic training and direct food intake training. Electrical stimulation was applied by an occupational therapist, using a modified hand-held battery-powered electrical stimulator (VitalStim® Dual Channel Unit and electrodes, Chattanooga Group, Hixson, TN, USA). Surface electromyography (sEMG), the Standardized Swallowing Assessment (SSA), Videofluoroscopic Swallowing Study (VFSS) and visual analog scale (VAS) were used to assess swallowing function before and 4 weeks after the treatment. The study included 118 subjects with dysphagia, 40 in the traditional swallowing therapy group and VitalStim® therapy group, 38 in the VitalStim and traditional swallowing therapy group. There were significant differences in sEMG value, SSA and VFSS scores in each group after the treatment (P < 0.001). After 4-week treatment, sEMG value (917.1 ± 91.2), SSA value (21.8 ± 3.5), oral transit time (0.4 ± 0.1) and pharyngeal

In the selection of Parkinson patients for deep brain stimulation (DBS) of the subthalamic nucleus (STN) a risk-benefit-analysis is performed regarding symptoms that commonly improve and symptoms that may deteriorate. Speech is among the symptoms that may deteriorate. In contrast, the differential effects of STN-DBS on swallowing are less clear. Here, we present a Parkinson patient with dysphagia from concomitant oculo-pharyngeal muscle dystrophy successfully treated by STN-DBS. The role of dysphagia in evaluating Parkinson patients for STN-DBS is discussed.

Clinician-reported toxicity grading through common terminology criteria for adverse events (CTCAE) stages dysphagia based on symptoms, diet, and tube dependence. The new dynamic imaging grade of swallowing toxicity (DIGEST) tool offers a similarly scaled five-point ordinal summary grade of pharyngeal swallowing as determined through results of a modified barium swallow (MBS) study. This study aims to inform clinicians on the similarities and differences between dysphagia severity according to clinical CTCAE and MBS-derived DIGEST grading. A cross-sectional sample of 95 MBS studies was randomly selected from a prospectively-acquired MBS database among patients treated with organ preservation strategies for head and neck cancer. MBS DIGEST and clinical CTCAE dysphagia grades were compared. DIGEST and CTCAE dysphagia grades had "fair" agreement per weighted κ of 0.358 (95% CI .231-.485). Using a threshold of DIGEST ≥ 3 as reference, CTCAE had an overall sensitivity of 0.50, specificity of 0.84, and area under the curve (AUC) of 0.67 to identify severe MBS-detected dysphagia. At less than 6 months, sensitivity was 0.72, specificity was 0.76, and AUC was 0.75 while at greater than 6 months, sensitivity was 0.22, specificity was 0.90, and AUC was 0.56 for CTCAE to detect dysphagia as determined by DIGEST. Classification of pharyngeal dysphagia on MBS using DIGEST augments our understanding of dysphagia severity according to the clinically-derived CTCAE while maintaining the simplicity of an ordinal scale. DIGEST likely complements CTCAE toxicity grading through improved specificity for physiologic dysphagia in the acute phase and improved sensitivity for dysphagia in the late-phase.

The motility of the pharynx, upper esophageal sphincter (UES), and proximal esophagus in patients with oropharyngeal dysphagia is still not entirely understood. High-resolution manometry (HRM) was recently added to the armamentarium for the study of this area. This study aims to describe HRM findings in patients with vagal paralysis. Sixteen patients (mean age 54 years, 69% females) with oropharyngeal dysphagia due to unilateral vagal paralysis were prospectively studied. All patients underwent HRM. Motility of the UES and at the topography of the velopharynx and epiglottis were recorded. (1) UES relaxation is compromised in a minority of patients, (2) epiglottis pressure does not follow a specific pattern, (3) vellum is hypotonic in half of the patients, (4) dysphagia is related to a low pharyngeal pressure, not to a flow obstruction at the level of the UES, and (5) aspiration is related to low pressures at the level of the UES and epiglottis and higher pressures at the level of the vellum. Pharyngeal motility is significantly impaired in patients with oropharyngeal dysphagia and unilateral vagal paralysis. In half of the cases, UES resting pressure is preserved due to unilateral innervation and relaxation is normal in most patients. Dysphagia therapy in these patients must be directed toward improvement in the oropharyngeal motility not at the UES.

Duchenne muscular dystrophy (DMD) is a rapidly progressive neuromuscular disorder causing weakness of the skeletal, respiratory, cardiac and oropharyngeal muscles with up to one third of young men reporting difficulty swallowing (dysphagia). Recent studies on dysphagia in DMD clarify the pathophysiology of swallowing disorders and offer new tools for its assessment but little guidance is available for its management. This paper aims to provide a step-by-step algorithm to facilitate clinical decisions regarding dysphagia management in this patient population. This algorithm is based on 30 years of clinical experience with DMD in a specialised Centre for Neuromuscular Disorders (Inkendaal Rehabilitation Hospital, Belgium) and is supported by literature where available. Dysphagia can worsen the condition of ageing patients with DMD. Apart from the difficulties of chewing and oral fragmentation of the food bolus, dysphagia is rather a consequence of an impairment in the pharyngeal phase of swallowing. By contrast with central neurologic disorders, dysphagia in DMD accompanies solid rather than liquid intake. Symptoms of dysphagia may not be clinically evident; however laryngeal food penetration, accumulation of food residue in the pharynx and/or true laryngeal food aspiration may occur. The prevalence of these issues in DMD is likely underestimated. There is little guidance available for clinicians to manage dysphagia and improve feeding for young men with DMD. This report aims to provide a clinical algorithm to facilitate the diagnosis of dysphagia, to identify the symptoms and to propose practical recommendations to treat dysphagia in the adult DMD population. Implications for Rehabilitation Little guidance is available for the management of dysphagia in Duchenne dystrophy. Food can penetrate the vestibule, accumulate as residue or cause aspiration. We propose recommendations and an algorithm to guide management of dysphagia. Penetration/residue accumulation

Tongue function can affect both the oral and pharyngeal stages of the swallowing process, and proper tongue strength is vital for safe oropharyngeal swallowing. This trial investigated the effect of tongue-to-palate resistance training (TPRT) on tongue strength and oropharyngeal swallowing function in stroke with dysphagia patients. This trial was performed using a 4-week, two-group, pre-post-design. Participants were allocated to the experimental group (n = 18) or the control group (n = 17). The experimental group performed TPRT for 4 weeks (5 days per week) and traditional dysphagia therapy, whereas the control group performed traditional dysphagia therapy on the same schedule. Tongue strength was measured using the Iowa Oral Performance Instrument. Swallowing function was measured using the videofluoroscopic dysphagia scale (VDS) and penetration-aspiration scale (PAS) based on a videofluoroscopic swallowing study. Experimental group showed more improved in the tongue strength (both anterior and posterior regions, P = 0·009, 0·015). In addition, the experimental group showed more improved scores on the oral and pharyngeal phase of VDS (P = 0·029, 0·007), but not on the PAS (P = 0·471), compared with the control group. This study demonstrated the effectiveness of TPRT in increasing tongue muscle strength and improving swallowing function in patients with post-stroke dysphagia. Therefore, we recommend TPRT as an easy and simple rehabilitation strategy for improving swallowing in patients with dysphagia. © 2016 John Wiley & Sons Ltd.

2016-01-01

Dysphagia is reported to be a common secondary complication for individuals with traumatic spinal injuries. Different etiologies of traumatic spinal injuries may lead to different profiles of swallowing impairment. We conducted a systematic review to determine the characteristics of dysphagia after traumatic spinal injury and to describe interventions currently used to improve swallowing function in this population. A comprehensive multi-engine literature search identified 137 articles of which 5 were judged to be relevant. These underwent review for study quality, rating for level of evidence, and data extraction. The literature describing dysphagia after traumatic spinal injury was comprised predominantly of low level evidence and single case reports. Aspiration, pharyngeal residue, and decreased/absent hyolaryngeal elevation were found to be common characteristics of dysphagia in this population. The most commonly used swallowing interventions included tube feeding, compensatory swallowing strategies, and steroids/antibiotics. Improvement in swallowing function following swallowing intervention was reported in all studies, however there was no control for spontaneous recovery. The results demonstrate a need for high-quality research to profile the pathophysiology of dysphagia after traumatic spinal injury and controlled studies to demonstrate the efficacy of swallowing interventions in this population.

Objective Dysphagia develops with low frequency in patients with dermatomyositis. Our objective was to determine the clinical and laboratory features that can estimate the development of dysphagia in dermatomyositis. Methods This study included 92 Japanese patients with adult-onset dermatomyositis. The associations between dysphagia and clinical and laboratory features including disease-specific autoantibodies determined by immunoprecipitation assays were analyzed. Results Videofluoroscopy swallow study (VFSS) was performed for all patients with clinical dysphagia (n = 13, 14.1%) but not for patients without clinical dysphagia. Typical findings of dysphagia (pharyngeal pooling, n = 11 and/or nasal regurgitation, n = 4) was detected by VFSS in all patients with clinical dysphagia. Eleven patients with dysphagia (84.6%) had anti-transcription intermediary factor 1γ (TIF-1γ) antibody. By univariate analysis, the average age and the male to female ratio, internal malignancy, and anti-TIF-1γ antibody were significantly higher and the frequency of interstitial lung diseases and manual muscle testing (MMT) scores of sternomastoid and dertoid muscles were significantly lower in patients with dysphagia than in patients without dysphagia. Among patients with anti-TIF-1γ antibody, the mean age, the ratios of male to female and internal malignancy were significantly higher and mean MMT scores of sternomastoid muscle were significantly lower in patients with dysphagia compared with patients without dysphagia. By multivariable analysis, the risk of dysphagia was strongly associated with the existence of internal malignancy and ant-TIF-1γ antibody and was also associated with reduced scores of manual muscle test of sternomastoid muscle. Dysphagia was markedly improved after the treatment against myositis in all 13 patients. Conclusion These findings indicate that dysphagia can develop frequently in patients with internal malignancy, anti-TIF-1γ antibody, or severe muscle

Dysphagia develops with low frequency in patients with dermatomyositis. Our objective was to determine the clinical and laboratory features that can estimate the development of dysphagia in dermatomyositis. This study included 92 Japanese patients with adult-onset dermatomyositis. The associations between dysphagia and clinical and laboratory features including disease-specific autoantibodies determined by immunoprecipitation assays were analyzed. Videofluoroscopy swallow study (VFSS) was performed for all patients with clinical dysphagia (n = 13, 14.1%) but not for patients without clinical dysphagia. Typical findings of dysphagia (pharyngeal pooling, n = 11 and/or nasal regurgitation, n = 4) was detected by VFSS in all patients with clinical dysphagia. Eleven patients with dysphagia (84.6%) had anti-transcription intermediary factor 1γ (TIF-1γ) antibody. By univariate analysis, the average age and the male to female ratio, internal malignancy, and anti-TIF-1γ antibody were significantly higher and the frequency of interstitial lung diseases and manual muscle testing (MMT) scores of sternomastoid and dertoid muscles were significantly lower in patients with dysphagia than in patients without dysphagia. Among patients with anti-TIF-1γ antibody, the mean age, the ratios of male to female and internal malignancy were significantly higher and mean MMT scores of sternomastoid muscle were significantly lower in patients with dysphagia compared with patients without dysphagia. By multivariable analysis, the risk of dysphagia was strongly associated with the existence of internal malignancy and ant-TIF-1γ antibody and was also associated with reduced scores of manual muscle test of sternomastoid muscle. Dysphagia was markedly improved after the treatment against myositis in all 13 patients. These findings indicate that dysphagia can develop frequently in patients with internal malignancy, anti-TIF-1γ antibody, or severe muscle weakness of sternomastoid muscle.

Dysphagia is an important issue in the prognosis of Parkinson's disease (PD). Although several studies have reported that oropharyngeal dysphagia may be associated with cognitive dysfunction, the exact relationship between cortical function and swallowing function in PD patients is unclear. Therefore, we investigated the association between an electrophysiological marker of central cholinergic function, which reflected cognitive function, and swallowing function, as measured by videofluoroscopic studies (VFSS). We enrolled 29 early PD patients. Using the Swallowing Disturbance Questionnaire (SDQ), we divided the enrolled patients into two groups: PD with dysphagia and PD without dysphagia. The videofluoroscopic dysphagia scale (VDS) was applied to explore the nature of the dysphagia. To assess central cholinergic dysfunction, short latency afferent inhibition (SAI) was evaluated. We analyzed the relationship between central cholinergic dysfunction and oropharyngeal dysphagia and investigated the characteristics of the dysphagia. The SAI values were significantly different between the two groups. The comparison of each VFSS component between the PD with dysphagia group and the PD without dysphagia group showed statistical significance for most of the oral phase components and for a single pharyngeal phase component. The total score on the VDS was higher in the PD with dysphagia group than in the PD without dysphagia group. The Mini-Mental State Examination and SAI values showed significant correlations with the total score of the oral phase components. According to binary logistic regression analysis, SAI value independently contributed to the presence of dysphagia in PD patients. Our findings suggest that cholinergic dysfunction is associated with dysphagia in early PD and that an abnormal SAI value is a good biomarker for predicting the risk of dysphagia in PD patients.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Eisbruch, Avraham; Levendag, Peter C.; Feng, Felix Y.

Purpose: Dysphagia is a major late complication of intensive chemoradiotherapy of head and neck cancer. The initial clinical results of intensity-modulated radiotherapy (IMRT), or brachytherapy, planned specifically to reduce dysphagia are presented. Patients and Methods: Previous research at Michigan University has suggested that the pharyngeal constrictors and glottic and supraglottic larynx are likely structures whose damage by chemo-RT causes dysphagia and aspiration. In a prospective Michigan trial, 36 patients with oropharyngeal (n = 31) or nasopharyngeal (n = 5) cancer underwent chemo-IMRT. IMRT cost functions included sparing noninvolved pharyngeal constrictors and the glottic and supraglottic larynx. After a review ofmore » published studies, the retropharyngeal nodes at risk were defined as the lateral, but not the medial, retropharyngeal nodes, which facilitated sparing of the swallowing structures. In Rotterdam, 77 patients with oropharyngeal cancer were treated with IMRT, three dimensional RT, or conventional RT; also one-half received brachytherapy. The dysphagia endpoints included videofluoroscopy and observer-assessed scores at Michigan and patient-reported quality-of-life instruments in both studies. Results: In both studies, the doses to the upper and middle constrictors correlated highly with the dysphagia endpoints. In addition, doses to the glottic and supraglottic larynx were significant in the Michigan series. In the Rotterdam series, brachytherapy (which reduced the doses to the swallowing structures) was the only significant factor on multivariate analysis. Conclusion: The dose-response relationships for the swallowing structures found in these studies suggest that reducing their doses, using either IMRT aimed at their sparing, or brachytherapy, might achieve clinical gains in dysphagia.« less

Purpose: To evaluate late dysphagia after chemoradiotherapy for locally advanced head-and-neck squamous cell carcinoma, and to examine its correlation with clinical and dosimetric parameters. Methods and Materials: Consecutive patients, treated with radiotherapy (70-72 Gy) and concomitant chemotherapy (cisplatinum 100 mg/m{sup 2} every 3 weeks) between 2004 and 2007, were examined. Swallowing was evaluated by four quality-of-life questionnaires: EORTC C30 and H and N35, the Performance Status Scale of List, and the MD Anderson Dysphagia Inventory. Clinical and dosimetric parameters were correlated with late dysphagia. Results: A total of 53 disease-free patients were evaluated; mean follow-up was 20.4 months (range, 6-45more » months). The volume of the middle pharyngeal constrictor muscle receiving {>=}50 Gy (p = 0.04), the mean dose to this structure (p = 0.02) and to the supraglottic larynx (p = 0.04) were significantly associated with late swallowing problems at univariate analysis, along with tumor localization (p = 0.008), T-classification (p = 0.02), and pretreatment swallowing problems (p = 0.01). Only this last factor significantly correlated with late dysphagia at multivariate analysis. Conclusion: These findings motivate further efforts to reduce the dose to the swallowing structures, especially to the pharyngeal constrictor muscles and the larynx. However, clinical parameters are also important and should be included in future prospective trials.« less

Oropharyngeal dysphagia is highly prevalent in stroke patients, with a high mortality and morbidity. Neuromuscular electrostimulation (NMES) is a new and potentially useful therapy. We assessed the therapeutic effectiveness and safety of NMES in the treatment of oropharyngeal dysphagia in patients with stroke. Prospective study of stroke patients, with tracheal aspiration revealed by videofluoroscopy (VDF), who underwent conventional therapy of oropharyngeal dysphagia as well as NMES. We did a follow-up at the end of the treatment and 3 months later. Patients underwent 18 courses of treatment (15-20) with a mean stimulation intensity of 12.45mA (range: 6.6-16.7mA). Before starting therapy, 8 patients were fed exclusively by means of a gastrostomy tube; after the treatment, only one patient needed it. No patient had complications. VDF parameters before treatment: oral transition time, swallowing reflex shooting (SRS) and pharyngeal transition time were longer and the hyoid elevation was reduced. After the treatment, the number of patients with tracheal aspiration decreased to 6, but only in 6 it persisted for the three analyzed viscosities (liquid, nectar and pudding), with an overall improvement of the VDF parameters. The only predictive factor of therapeutic effectiveness was the delay in the SRS. NMES is an effective and safe treatment for stroke patients with oropharyngeal dysphagia.

Deformities of the anterior cervical spine are an established cause of dysphagia. Whereas osteophytes and spinal fusion hardware have been reported to alter bolus flow and contribute to swallowing dysfunction, the relationship between abnormal spine curvature and swallowing dysfunction is not established. The purpose of this investigation was to evaluate the association between cervical kyphosis and objective measures of swallowing dysfunction on videofluoroscopy. Case-control study of patients presenting to tertiary dysphagia center. All videofluoroscopic swallow studies (VFSS) performed at our institution, between August 1, 2014, and August 1, 2015, were retrospectively reviewed to identify patients with abnormal cervical kyphosis, according to Cobb and Jackson angle measurements. Patients with kyphosis were age- and gender-matched to persons without kyphosis. VFSS and demographic parameters were collected and compared between groups. Thirty-six patients with cervical kyphosis exceeding two standard deviations (SD) beyond established age-specific normal ranges were identified. The mean age of the entire cohort was 61.6 (SD ±19.1) years. Mean pharyngeal area was 3.34 cm 2 greater in kyphosis patients compared to controls (95% confidence interval [CI]: 0.47-5.21 cm 2 ; P = .0007). This was associated with increased hypopharyngeal transit time (0.57 seconds, 95% CI: 0.045-1.09 seconds, P = .034), and higher prevalence of penetration (P = .014). There was no significant difference in the pharyngeal constriction ratio (PCR), a surrogate measure of pharyngeal strength (P = .83). Patients with cervical spine kyphosis have a significantly dilated pharynx (P = .0007), elongated hypopharyngeal transit time (P = .034), and worsened penetration aspiration scores (P = .021). Absence of a difference in PCR suggests adequate compensation as a group. 3b. Laryngoscope, 127:1832-1837, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

Pediatric dysphagia—feeding and swallowing difficulties that begin at birth, last throughout childhood, and continue into maturity—is one of the most common, least understood complications in children with developmental disorders. We argue that a major cause of pediatric dysphagia is altered hindbrain patterning during pre-natal development. Such changes can compromise craniofacial structures including oropharyngeal muscles and skeletal elements as well as motor and sensory circuits necessary for normal feeding and swallowing. Animal models of developmental disorders that include pediatric dysphagia in their phenotypic spectrum can provide mechanistic insight into pathogenesis of feeding and swallowing difficulties. A fairly common human genetic developmental disorder, DiGeorge/22q11.2 Deletion Syndrome (22q11DS) includes a substantial incidence of pediatric dysphagia in its phenotypic spectrum. Infant mice carrying a parallel deletion to 22q11DS patients have feeding and swallowing difficulties. Altered hindbrain patterning, neural crest migration, craniofacial malformations, and changes in cranial nerve growth prefigure these difficulties. Thus, in addition to craniofacial and pharyngeal anomalies that arise independently of altered neural development, pediatric dysphagia may reflect disrupted hindbrain patterning and its impact on neural circuit development critical for feeding and swallowing. The mechanisms that disrupt hindbrain patterning and circuitry may provide a foundation to develop novel therapeutic approaches for improved clinical management of pediatric dysphagia. PMID:26554723

Abstract Purpose: Duchenne muscular dystrophy (DMD) is a rapidly progressive neuromuscular disorder causing weakness of the skeletal, respiratory, cardiac and oropharyngeal muscles with up to one third of young men reporting difficulty swallowing (dysphagia). Recent studies on dysphagia in DMD clarify the pathophysiology of swallowing disorders and offer new tools for its assessment but little guidance is available for its management. This paper aims to provide a step-by-step algorithm to facilitate clinical decisions regarding dysphagia management in this patient population. Methods: This algorithm is based on 30 years of clinical experience with DMD in a specialised Centre for Neuromuscular Disorders (Inkendaal Rehabilitation Hospital, Belgium) and is supported by literature where available. Results: Dysphagia can worsen the condition of ageing patients with DMD. Apart from the difficulties of chewing and oral fragmentation of the food bolus, dysphagia is rather a consequence of an impairment in the pharyngeal phase of swallowing. By contrast with central neurologic disorders, dysphagia in DMD accompanies solid rather than liquid intake. Symptoms of dysphagia may not be clinically evident; however laryngeal food penetration, accumulation of food residue in the pharynx and/or true laryngeal food aspiration may occur. The prevalence of these issues in DMD is likely underestimated. Conclusions: There is little guidance available for clinicians to manage dysphagia and improve feeding for young men with DMD. This report aims to provide a clinical algorithm to facilitate the diagnosis of dysphagia, to identify the symptoms and to propose practical recommendations to treat dysphagia in the adult DMD population.Implications for RehabilitationLittle guidance is available for the management of dysphagia in Duchenne dystrophy.Food can penetrate the vestibule, accumulate as residue or cause aspiration.We propose recommendations and an algorithm to guide management of

Otter, Sophie; Schick, Ulrike; Gulliford, Sarah

Purpose: The study aimed to apply the atlas of complication incidence (ACI) method to patients receiving radical treatment for head and neck squamous cell carcinomas (HNSCC), to generate constraints based on dose-volume histograms (DVHs), and to identify clinical and dosimetric parameters that predict the risk of grade 3 oral mucositis (g3OM) and pharyngeal dysphagia (g3PD). Methods and Materials: Oral and pharyngeal mucosal DVHs were generated for 253 patients who received radiation (RT) or chemoradiation (CRT). They were used to produce ACI for g3OM and g3PD. Multivariate analysis (MVA) of the effect of dosimetry, clinical, and patient-related variables was performed usingmore » logistic regression and bootstrapping. Receiver operating curve (ROC) analysis was also performed, and the Youden index was used to find volume constraints that discriminated between volumes that predicted for toxicity. Results: We derived statistically significant dose-volume constraints for g3OM over the range v28 to v70. Only 3 statistically significant constraints were derived for g3PD v67, v68, and v69. On MVA, mean dose to the oral mucosa predicted for g3OM and concomitant chemotherapy and mean dose to the inferior constrictor (IC) predicted for g3PD. Conclusions: We have used the ACI method to evaluate incidences of g3OM and g3PD and ROC analysis to generate constraints to predict g3OM and g3PD derived from entire individual patient DVHs. On MVA, the strongest predictors were radiation dose (for g3OM) and concomitant chemotherapy (for g3PD).« less

Introduction The literature presents studies correlating chronic obstructive pulmonary disease to dysphagia and suggesting that the aspiration laryngeal phenomenon related to changes in the pharyngeal phase contributes significantly to the exacerbation of symptoms of lung disease. Objectives This study aimed to conduct a literature review to identify the relation between dysphagia and exacerbations of chronic obstructive pulmonary disease. Data Synthesis We found 21 studies and included 19 in this review. The few studies that related to the subject agreed that the presence of dysphagia, due to lack of coordination between swallowing and breathing, may be one of the triggering factors of chronic obstructive pulmonary disease exacerbation. Conclusions The review noted that there is a relationship between dysphagia and exacerbations of chronic obstructive pulmonary disease, identified by studies demonstrating that the difficulties associated with swallowing may lead to exacerbation of the disease. There was difficulty in comparing studies by their methodological differences. More research is needed to clarify the relationship between dysphagia and exacerbations of chronic obstructive pulmonary disease, making it possible to develop multiprofessional treatment strategies for these patients, catered to specific needs due to the systemic manifestations of the disease.

Although dysphagia is a known complication of dermatomyositis, sudden onset of dysphagia without the notable aggravation of other symptoms can make the diagnosis and treatment challenging. A 53-year-old male diagnosed as dermatomyositis 1 month ago came to our emergency department complaining of a sudden inability to swallow solid foods and liquids. The patient showed generalized edema, but the muscle power was not different compared with 1 month ago. Serum creatine kinase level was lower than that measured 2 weeks ago. Computed tomography scan of the larynx, chest, abdomen, and pelvis, an esophagogastroduodenoscopy, and brain magnetic resonance imaging were unremarkable. A videofluoroscopic swallowing study revealed inadequate pharyngeal contraction and slightly decreased upper esophageal sphincter opening with silent aspiration. Treatment with oral prednisolone, intravenous methylprednisolone, azathioprine, and intravenous immunoglobulins was applied. During the course of medical treatment for life-threatening dysphagia, he continued with rehabilitative therapy. He could swallow saliva at 2 months and showed normal swallowing function at 3 months from the onset of dysphagia. Dysphagia has not recurred for 3 years after recovery. A multidisciplinary approach is necessary to diagnose severe acute dysphagia due to exacerbation of underlying dermatomyositis rather than other structural or neurological causes. Appropriate supportive care is important because dysphagia can be life-threatening and last for a long time.

Spinocerebellar ataxias (SCAs) are a group of neurodegenerative disorders frequently associated with autosomal dominant inheritance. SCA type 3 (SCA3) and SCA type 6 (SCA6) are the most common forms in Japan as well as the rest of the world. SCA3 affects multiple nervous systems while SCA6 affects mainly the cerebellar system. Dysphagia is clinically important since aspiration pneumonia is the most common cause of death in patients with SCA. We retrospectively studied dysphagia in 7 patients with SCA3 and 13 with SCA6 by videofluoroscopic examination of swallowing (VF). This is a larger series of patients with SCA6 than in previous studies, which had inconsistent results. Dysphagia was evaluated according to the scale established by the Japanese Society of Dysphagia Rehabilitation and the dysphagia outcome severity scale, an internationally used scale. The former separately evaluates oral and pharyngeal phases, while the latter concurrently grades both phases. Dysphagia according to the Japanese scale was mild but statistically significant in SCA6 and severe in SCA3. DOSS indicated abnormalities in SCA3 but not in SCA6. The swallowing abnormalities in SCA3 or SCA6 did not parallel the duration of disease or physical disability, suggesting that even patients with early disease or with well-preserved physical functions were at risk for aspiration. Our patients with dysphagia received percutaneous endoscopic gastrostomy-tube feeding at an appropriate time and underwent rehabilitation of swallowing. No patient had aspiration pneumonia. In conclusion, evaluation of swallowing ability by VF is essential for preventing aspiration in patients with SCA.

Dysphagia is a common symptom and an important prognostic factor in Parkinson's disease (PD). Although cognitive and motor dysfunctions may contribute to dysphagia in patients with PD, any specific association between such problems and swallowing functions is unclear. Here, we examined the potential relationship between cognitive/motor components and swallowing functions in PD. We evaluated the contributions of cognition and motor function to the components of swallowing via video fluoroscopic swallowing (VFS) experiments. We prospectively enrolled 56 patients without dementia having PD. Parkinson's disease severity was assessed by the Unified Parkinson's Disease Rating Scale (UPDRS). All participants received neuropsychological tests covering general mental status, visuospatial function, attention, language, learning and memory, and frontal executive function. The well-validated "modified barium swallow impairment profile" scoring system was applied during VFS studies to quantify swallowing impairments. Finally, correlations between neuropsychological or motor functions and impairment in swallowing components were calculated. The most significant correlations were found between the frontal/executive or learning/memory domains and the oral phase of swallowing, though a minor component of the pharyngeal phase correlated with frontal function as well. Bradykinesia and the UPDRS total score were associated with both the pharyngeal and oral phases. Our findings suggest that cognitive dysfunctions are associated with the oral phase of swallowing in patients with early stage PD while the severity of motor symptoms may be associated with overall swallowing function.

Dysphagia is reported to be a common secondary complication for individuals with traumatic spinal injuries. Different etiologies of traumatic spinal injuries may lead to different profiles of swallowing impairment. We conducted a systematic review to determine the characteristics of dysphagia after traumatic spinal injury and to describe interventions currently used to improve swallowing function in this population. A comprehensive multiengine literature search identified 137 articles of which five were judged to be relevant. These underwent review for study quality, rating for level of evidence, and data extraction. The literature describing dysphagia after traumatic spinal injury was comprised predominantly of low-level evidence and single case reports. Aspiration, pharyngeal residue, and decreased/absent hyolaryngeal elevation were found to be common characteristics of dysphagia in this population. The most commonly used swallowing interventions included tube feeding, compensatory swallowing strategies, and steroids/antibiotics. Improvement in swallowing function following swallowing intervention was reported in all studies; however, there was no control for spontaneous recovery. The results demonstrate a need for high-quality research to profile the pathophysiology of dysphagia after traumatic spinal injury and controlled studies to demonstrate the efficacy of swallowing interventions in this population.

To estimate the association between different dose-volume metrics of the salivary glands and pharyngeal constrictors with patient reported severity of xerostomia/dysphagia in the setting of deintensified chemoradiation therapy (CRT). Forty-five patients were treated on a phase 2 study assessing the efficacy of deintensified CRT for favorable-risk, HPV-associated oropharyngeal squamous cell carcinoma. Patients received 60 Gy intensity modulated radiation therapy with concurrent weekly cisplatin (30 mg/m 2 ), and reported the severity of their xerostomia/dysphagia (before and after treatment) using the patient-reported outcome version of the Common Terminology Criteria for Adverse Events (CTCAE) (PRO-CTCAE). Individual patient dosimetric data of the contralateral parotid and submandibular glands and pharyngeal constrictors were correlated with changes in PRO-CTCAE severity. A change in severity (from baseline) of ≥2 was considered clinically meaningful. Associations between dose-volume metrics and patient outcomes were assessed with receiver operating characteristic (ROC) curve and logistic regression model. Six months after CRT, patients reporting <2 change in xerostomia severity (n=14) had an average D mean = 22 ± 9 Gy to the sum of the contralateral glands (parotid + submandibular) compared with the patients reporting ≥2 change (n=21), who had an average D mean = 34 ± 8 Gy. V15 to V55 for the combined contralateral glands showed the strongest association with xerostomia (area under the curve [AUC] = 0.83-0.86). Based on the regression analysis, a 20% risk of toxicity was associated with V15 = 48%, V25 = 30%, and D mean =21 Gy. Six months after CRT, patients reporting <2 change in dysphagia severity (n=26) had an average V55 = 76 ± 13 (%) to the superior pharyngeal constrictor compared with the patients reporting ≥2 change in severity (n=9), who had average V55 = 89 ± 13 (%). V55to V60 had the strongest association with dysphagia (AUC = 0

Poststroke dysphagia rehabilitation by repetitive transcranial magnetic stimulation: a noncontrolled pilot study.

Poststroke dysphagia is frequent and significantly increases patient mortality. In two thirds of cases there is a spontaneous improvement in a few weeks, but in the other third, oropharyngeal dysphagia persists. Repetitive transcranial magnetic stimulation (rTMS) is known to excite or inhibit cortical neurons, depending on stimulation frequency. The aim of this noncontrolled pilot study was to assess the feasibility and the effects of 1-Hz rTMS, known to have an inhibitory effect, on poststroke dysphagia. Seven patients (3 females, age = 65 +/- 10 years), with poststroke dysphagia due to hemispheric or subhemispheric stroke more than 6 months earlier (56 +/- 50 months) diagnosed by videofluoroscopy, participated in the study. rTMS at 1 Hz was applied for 20 min per day every day for 5 days to the healthy hemisphere to decrease transcallosal inhibition. The evaluation was performed using the dysphagia handicap index and videofluoroscopy. The dysphagia handicap index demonstrated that the patients had mild oropharyngeal dysphagia. Initially, the score was 43 +/- 9 of a possible 120 which decreased to 30 +/- 7 (p < 0.05) after rTMS. After rTMS, there was an improvement of swallowing coordination, with a decrease in swallow reaction time for liquids (p = 0.0506) and paste (p < 0.01), although oral transit time, pharyngeal transit time, and laryngeal closure duration were not modified. Aspiration score significantly decreased for liquids (p < 0.05) and residue score decreased for paste (p < 0.05). This pilot study demonstrated that rTMS is feasible in poststroke dysphagia and improves swallowing coordination. Our results now need to be confirmed by a randomized controlled study with a larger patient population.

To determine laryngoscopic and videofluoroscopic swallowing study (VFSS) findings in geriatric patients with dysphagia; to evaluate management. Retrospective chart review. Patients over 65 years old complaining of dysphagia, seen at a tertiary laryngology clinic, were included. Head and neck cancer and stroke patients were excluded. Demographics, laryngoscopic findings, swallowing studies, and treatment modalities were reviewed. Sixty-five patients were included. Mean age was 75 years old (range = 66-97) with female predominance of 67.6%. Weight loss was seen in 9.2% of the patients. Whereas 52.3% of the patients complained of solid food dysphagia, 53.8% were choking on food. On laryngoscopy, 15.3% of the patients had pooling in the pyriform sinuses, 30.7% had glottic gap, 18.4% had vocal fold immobility, and 3% had hypomobility. VFSS showed that 38.4% of the patients had pharyngoesophageal dysphagia, 20% had oropharyngeal dysphagia, 20% had pharyngeal dysphagia, and 20% had a normal study. In addition, 41.5% of the patients showed laryngeal penetration and 18.4% showed aspiration. Surgical intervention was employed in 29.2% of the patients in the form of botulinum toxin injection, esophageal dilatation, cricopharyngeal myotomy, vocal fold injection, diverticulectomy, and percutaneous endoscopic gastrostomy. Whereas 21.5% of the patients received swallowing therapy, 61.5% underwent diet modification. As a result, 80% of the patients needed some type of treatment. Swallowing problems in older patients are not uncommon. The clinician needs to be diligent to inquire about dysphagia because a large number of these patients will require treatment. 4. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

Currently, the videofluoroscopic swallowing study (VFSS) is the standard tool for evaluating dysphagia. We evaluated whether the addition of endoscopist-directed flexible endoscopic evaluation of swallowing (FEES) to VFSS could improve the detection rates of penetration, aspiration, and pharyngeal residue, compared the diagnostic efficacy between VFSS and endoscopist-directed FEES and assessed the adverse events of the FEES. In single tertiary referral center, a retrospective analysis of prospectively collected data was conducted. Fifty consecutive patients suspected of oropharyngeal dysphagia were enrolled in this study between January 2012 and July 2012. The agreement in the detection of penetration and aspiration between VFSS and FEES of viscous food (κ=0.34; 95% confidence interval [CI], 0.15 to 0.53) and liquid food (κ=0.22; 95% CI, 0.02 to 0.42) was "fair." The agreement in the detection of pharyngeal residue between the two tests was "substantial" with viscous food (κ=0.63; 95% CI, 0.41 to 0.94) and "fair" with liquid food (κ=0.37; 95% CI, 0.10 to 0.63). Adding FEES to VFSS significantly increased the detection rates of penetration, aspiration, and pharyngeal residue. No severe adverse events were noted during FEES, except for two cases of epistaxis, which stopped spontaneously without requiring any packing. This study demonstrated that the addition of endoscopist-directed FEES to VFSS increased the detection rates of penetration, aspiration, and pharyngeal residue.

Rett syndrome (RS) is a neurodevelopmental disorder and the second major cause of mental retardation in females. The aim of this study was to evaluate swallowing problems of RS patients by endoscopic assessment and compile a list of suggestions for managing feeding and preventing complications. The sample consisted of 61 female patients (mean age = 13.6 years, range, 2-33 years) admitted to the Department of Neuropsychiatry, where they had previously been diagnosed with RS. Speech evaluation associated with observation during mealtimes was useful to formulate suggestions for caregivers. Progressive deterioration of feeding was commonly noted by caregivers. Fifty-four patients had a history of recurrent episodes of bronchitis. Oral apraxia, dyskinetic tongue movements, prolonged oral stage, and poor bolus formation were the most common findings in all patients. Dysphagia was primarily limited to oral preparatory phases, while the pharyngeal phase was normal in most patients. The high percentage of dysphagia suggests the need to accurately monitor the feeding capability of RS children. It is critical to correctly inform caregivers about safe swallowing procedures to reduce the incidence of fatal complications.

Oropharyngeal dysphagia (OPD) is a challenging and relatively common condition in children. Both developmentally normal and delayed children may be affected. The etiology of OPD is frequently multifactorial with neurologic, inflammatory, and anatomic conditions contributing to discoordination of the pharyngeal phase of swallowing. Depending on the severity and source, OPD may persist for several years with significant burden to a patient's health and family. This article details current understanding of the mechanism and potential sources of OPD in children while providing an algorithm for managing it in the acute and chronic setting.

2009-01-01

The aim of this work was to assess the efficacy of external myotomy of the upper esophageal sphincter (UES) for oropharyngeal dysphagia. In the period 1991–2006, 28 patients with longstanding dysphagia and/or aspiration problems of different etiologies underwent UES myotomy as a single surgical treatment. The main symptoms were difficulties in swallowing of a solid-food bolus, aspiration, and recurrent incidents of solid-food blockages. Pre- and postoperative manometry and videofluoroscopy were used to assess deglutition and aspiration. Outcome was defined as success in the case of complete relief or marked improvement of dysphagia and aspiration and as failure in the case of partial improvement or no improvement. Initial results showed success in 21 and failure in 7 patients. The best outcomes were observed in patients with dysphagia of unknown origin, noncancer-related iatrogenic etiology, and neuromuscular disease. No correlation was found between preoperative constrictor pharyngeal muscle activity and success rate. After follow-up of more than 1 year, 20 patients were marked as success and 3 as failure. All successful patients had full oral intake with a normal bolus consistency without clinically significant aspiration. We conclude that in select cases of oropharyngeal dysphagia success may be achieved by UES myotomy with restoration of oral intake of normal bolus consistency. PMID:19760460

Objectives To determine symptoms and findings in patients with dysphagia related to epiglottic dysfunction. To analyze outcomes in patients who underwent partial epiglottidectomy due to dysphagia related to epiglottic dysfunction Study Design Review and analysis of clinical data obtained as part of the diagnosis and treatment of patients with dysphagia related to epiglottic dysfunction. Methods A retrospective review was performed of all post-treatment head and neck cancer patients who underwent epiglottidectomy at a single tertiary care referral center. Objective pre- and post-procedure swallow findings, endoscopic evaluation, and subjective improvement based on patient self-report were reviewed. Results Seven patients were identified based on endoscopic evaluation and modified barium swallow study (MBSS) as having epiglottic pathology leading to dysphagia. Specific anatomic and functional findings included thickening of the epiglottis, absence of epiglottic deflection, vallecular bolus retention during and after the swallow, and bolus backflow from the pharynx to the oral or nasal cavity. Partial epiglottidectomy was performed in these patients. Post-operative MBSS was analyzed for changes in swallow efficiency and safety. Nearly all patients demonstrated improved pharyngeal bolus passage with little to no added swallowing morbidity. Conclusions Preliminary findings suggest a role for partial epiglottidectomy in post-treatment head and neck cancer patients with swallowing disorders. Ideal candidates have intact tongue base contraction and poor retroflexion of the epiglottis, which result in bolus obstruction at the level of the valleculae. Partial epiglottic resection enables improved bolus passage in the pharyngeal phase. Minimal post-operative morbidity occurs in the appropriately selected patient. PMID:23794244

The aim of this study was to evaluate dysphagia in patients with head and neck cancer (HNC) undergoing three-dimensional conformal radiation therapy using objective and subjective tools simultaneously and to associate the clinical correlates of dysphagia with dosimetric parameters. Twenty patients were included in the study. The primary tumor and the involved lymph nodes (LN) were treated with 66-70 Gy, the uninvolved LN were treated with 46-50 Gy. Six swallowing structures were identified: the superior pharyngeal constrictor muscle (SPCM), the middle pharyngeal constrictor muscle (MPCM), the inferior pharyngeal constrictor muscle (IPCM), the base of tongue (BOT), the larynx and the proximal esophageal sphincter (PES). Dysphagia was evaluated using videofluoroscopy and European Organization for Research and Treatment of Cancer (EORTC) QoL questionnaire (QLQ-C30) and supplemental EORTC QoL module for HNC (QLQ-H&N35). The evaluations were performed before treatment, at 3 months and at 6 months following treatment. On objective evaluation, the Dmax for the larynx and the sub-structures of the PCM were correlated with impaired lingual movement, BOT weakness and proximal esophageal stricture at 3 months, whereas the V65, the V70and the Dmax for the larynx was correlated with BOT weakness and the V65, the V70, the Dmax or the Dmean for the sub-structures of the PCM were correlated with impaired lingual movement, BOT weakness, reduced laryngeal elevation, reduced epiglottic inversion and aspiration at 6 months following treatment. On subjective evaluation, the V60, the Dmax and the Dmean for SPCM were correlated with QoL scores for HNSO at 3 months, whereas the V70 for SPCM were correlated with QoL scores for HNPA and the V60, the V65, the V70, the Dmax and the Dmean for SPCM were correlated with QoL scores for HNSO at 6 months following treatment.

Summary Laryngeal endoscopy plays a determinant role in clinical evaluation of dysphagia. The examination is performed by means of a trans-nasal approach with a flexible fiberoptic endoscope, able to visualize the pre- and post-deglutitory steps of the pharyngeal phase of swallowing. In patients with tracheostomy, it is possible to visualize the glottic or neoglottic function during the intra-deglutitory phase, performing the examination through a trans-tracheostomic route. The procedure and indications of this endoscopic technique are described. PMID:18320834

Swallowing impairment (dysphagia) is a common sequela in patients with motor neuron disease (MND). The purpose of this retrospective, observational pilot investigation was to characterize how pharyngeal swallowing mechanics are impacted in patients with MND using a comparison with healthy, non-dysphagic control group. Computational analysis of swallowing mechanics (CASM) was used to determine covariate biomechanics of pharyngeal swallowing from videofluoroscopic assessment in 15 patients with MND and 15 age- and sex-matched healthy controls. Canonical variant analysis with post hoc discriminate function analysis (DFA) was performed on coordinate data mapping functional muscle groups underlying pharyngeal swallowing. Differences in swallowing mechanics associated with group (MND; control), motor neuron predominance (upper; lower), onset (bulbar; spinal), and swallow task (thin, pudding) were evaluated and visualized. Pharyngeal swallowing mechanics differed significantly in patients with MND compared with healthy controls (D = 2.01, p < 0.0001). Post hoc DFA pairwise comparisons suggest differences in pharyngeal swallow mechanics by motor neuron predominance (D = 5.03, p < 0.0001), onset (D = 2.03, p < 0.0001), and swallow task (D = 1.04, p < 0.0001). Pharyngeal swallowing mechanics of patients with MND differ from and are more heterogeneous than healthy controls. These findings suggest patients with MND may compensate reductions in pharyngeal shortening and tongue base retraction by extending the head and neck and increasing hyolaryngeal excursion. This work and further CASM investigations will lead to further insights into development and evaluation of targeted clinical treatments designed to prolong safe and efficient swallowing function in patients with MND.

We summarize the characteristics of dysphagia in 9 infants in Brazil with microcephaly caused by congenital Zika virus infection. The Schedule for Oral Motor Assessment, fiberoptic endoscopic evaluation of swallowing, and the videofluoroscopic swallowing study were used as noninstrumental and instrumental assessments. All infants had a degree of neurologic damage and showed abnormalities in the oral phase. Of the 9 infants, 8 lacked oral and upper respiratory tract sensitivity, leading to delays in initiation of the pharyngeal phase of swallowing. Those delays, combined with marked oral dysfunction, increased the risk for aspiration of food, particularly liquid foods. Dysphagia resulting from congenital Zika virus syndrome microcephaly can develop in infants >3 months of age and is severe.

To determine the prevalence of oropharyngeal dysphagia (OPD) and its subtypes (oral phase, pharyngeal phase, saliva control), and their relationship to gross motor functional skills in preschool children with cerebral palsy (CP). It was hypothesized that OPD would be present across all gross motor severity levels, and children with more severe gross motor function would have increased prevalence and severity of OPD. Children with a confirmed diagnosis of CP, 18 to 36 months corrected age, born in Queensland between 2006 and 2009, participated. Children with neurodegenerative conditions were excluded. This was a cross-sectional population-based study. Children were assessed by using 2 direct OPD measures (Schedule for Oral Motor Assessment; Dysphagia Disorders Survey), and observations of signs suggestive of pharyngeal phase impairment and impaired saliva control. Gross motor skills were described by using the Gross Motor Function Measure, Gross Motor Function Classification System (GMFCS), Manual Ability Classification System, and motor type/ distribution. OPD was prevalent in 85% of children with CP, and there was a stepwise relationship between OPD and GMFCS level. There was a significant increase in odds of having OPD, or a subtype, for children who were nonambulant (GMFCS V) compared with those who were ambulant (GMFCS I) (odds ratio = 17.9, P = .036). OPD was present across all levels of gross motor severity using direct assessments. This highlights the need for proactive screening of all young children with CP, even those with mild impairments, to improve growth and nutritional outcomes and respiratory health.

Summary Introduction: In the literature, the incidence of oropharyngeal dysphagia in patients with cerebrovascular accident (AVE) ranges 20–90%. Some studies correlate the location of a stroke with dysphagia, while others do not. Objective: To correlate brain injury with dysphagia in patients with stroke in relation to the type and location of stroke. Method: A prospective study conducted at the Hospital de Clinicas with 30 stroke patients: 18 women and 12 men. All patients underwent clinical evaluation and swallowing nasolaryngofibroscopy (FEES®), and were divided based on the location of the injury: cerebral cortex, cerebellar cortex, subcortical areas, and type: hemorrhagic or transient ischemic. Results: Of the 30 patients, 18 had ischemic stroke, 10 had hemorrhagic stroke, and 2 had transient stroke. Regarding the location, 10 lesions were in the cerebral cortex, 3 were in the cerebral and cerebellar cortices, 3 were in the cerebral cortex and subcortical areas, and 3 were in the cerebral and cerebellar cortices and subcortical areas. Cerebral cortex and subcortical area ischemic strokes predominated in the clinical evaluation of dysphagia. In FEES®, decreased laryngeal sensitivity persisted following cerebral cortex and ischemic strokes. Waste in the pharyngeal recesses associated with epiglottic valleculae predominated in the piriform cortex in all lesion areas and in ischemic stroke. A patient with damage to the cerebral and cerebellar cortices from an ischemic stroke exhibited laryngeal penetration and tracheal aspiration of liquid and honey. Conclusion: Dysphagia was prevalent when a lesion was located in the cerebral cortex and was of the ischemic type. PMID:25991951

Oropharyngeal dysphagia is an important disability that occurs after stroke; it contributes to aspiration pneumonia and death, and current modalities for rehabilitation of dysphagia have uncertain efficacy. We therefore examined the role of pharyngeal electrical stimulation (PES) in expediting human swallowing recovery after experimental (virtual) and actual (stroke) brain lesions. First, healthy subjects (n = 13) were given 1-Hz repetitive transcranial magnetic stimulation to induce a unilateral virtual lesion in pharyngeal motor cortex followed by active or sham (control) PES. Motor-evoked potentials and swallow accuracy were recorded before and after the lesion to assess PES response. Thereafter, 50 acute dysphagic stroke patients underwent either a dose-response study, to determine optimal parameters for PES (n = 22), or were assigned randomly to groups given either active or sham (control) PES (n = 28). The primary end point was the reduction of airway aspiration at 2 weeks postintervention. In contrast to sham PES, active PES reversed the cortical suppression induced by the virtual lesion (F(7,70) = 2.7; P = .015) and was associated with improvement in swallowing behavior (F(3,42) = 5; P = .02). After stroke, 1 PES treatment each day (U = 8.0; P = .043) for 3 days (U = 10.0) produced improved airway protection compared with controls (P = .038). Active PES also reduced aspiration (U = 54.0; P = .049), improved feeding status (U = 58.0; P = .040), and resulted in a shorter time to hospital discharge (Mantel-Cox log-rank test, P = 0.038). This pilot study of PES confirms that it is a safe neurostimulation intervention that reverses swallowing disability after virtual lesion or stroke. Copyright 2010 AGA Institute.

Lundine, Jennifer P.; Bates, David G.; Yin, Han

2015-01-01

Background Aspiration of liquids is a serious complication of neurological impairments such as traumatic brain injury or stroke. Carbonated liquids have been examined as a possible alternative to thickened liquids to help reduce aspiration in cases of dysphagia in adults, but no published literature to the best of our knowledge has evaluated this technique in children. If carbonated liquids result in safer swallowing in children, they could provide a preferred alternative to thickened liquids. Objective This pilot study examined whether carbonated thin liquids (CARB) improved swallowing compared to noncarbonated thin liquids (NOCARB) for children with neurogenic dysphagia. Materials and methods Twenty-four children admitted to a level I trauma center for acute neurological injury/disease were evaluated via videofluoroscopic swallow studies. Four descriptive outcome measures were contrasted. Results CARB significantly decreased pooling (P=0.0006), laryngeal penetration/aspiration (P=0.0044) and Penetration-Aspiration Scale scores (P=0.0127) when compared to NOCARB. On average, CARB improved scores on the Penetration-Aspiration Scale by 3.7 points for participants who aspirated NOCARB. There was no significant difference in pharyngeal residue noted between CARB and NOCARB (P=0.0625). Conclusion These findings support the hypothesis that carbonated thin liquids may provide an alternative to thickened liquids for children with neurogenic dysphagia. Implications for future research and clinical practice are discussed. PMID:25758792

The development of innovative experimental approaches is necessary to gain insights in the complex biomechanics of swallowing. In particular, unraveling the mechanisms of formation of the thin film of bolus coating the pharyngeal mucosa after the ingestion of liquid or semi-liquid food products is an important challenge, with implication in dysphagia treatment and sensory perceptions. The aim here is to propose an original experimental model of swallowing (i) to simulate the peristaltic motions driving the bolus from the oral cavity to the esophagus, (ii) to mimic and vary complex physiological variables of the pharyngeal mucosa (lubrication, deformability and velocity) and (iii) to measure the thickness and the composition of the coatings resulting from bolus flow. Three Newtonian glucose solutions were considered as model food boli, through sets of experiments covering different ranges of each physiological parameter mimicked. The properties of the coatings (thickness and dilution in saliva film) were shown to depend significantly on the physical properties of food products considered (viscosity and density), but also on physiological variables such as lubrication by saliva, velocity of the peristaltic wave, and to a lesser extent, the deformability of the pharyngeal mucosa. The biomechanical peristalsis simulator developed here can contribute to unravel the determinants of bolus adhesion on pharyngeal mucosa, necessary both for the design of alternative food products for people affected by swallowing disorders, and for a better understanding of the dynamic mechanisms of aroma perception.

Huckabee, Maggie-Lee; Doeltgen, Sebastian

2007-10-12

The aim of this review article is to advise the New Zealand medical community about the application of neuromuscular electrical stimulation (NMES) as a treatment for pharyngeal swallowing impairment (dysphagia). NMES in this field of rehabilitation medicine has quickly emerged as a widely used method overseas but has been accompanied by significant controversy. Basic information is provided about the physiologic background of electrical stimulation. The literature reviewed in this manuscript was derived through a computer-assisted search using the biomedical database Medline to identify all relevant articles published until from the initiation of the databases up to January 2007. The reviewers used the following search strategy: [(deglutition disorders OR dysphagia) AND (neuromuscular electrical stimulation OR NMES)]. In addition, the technique of reference tracing was used and very recently published studies known to the authors but not yet included in the database systems were included. This review elucidates not only the substantive potential benefit of this treatment, but also potential key concerns for patient safety and long term outcome. The discussion within the clinical and research communities, especially around the commercially available VitalStim stimulator, is objectively explained.

Surface electromyography as a screening method for evaluation of dysphagia and odynophagia

Vaiman, Michael; Eviatar, Ephraim

2009-01-01

Objective Patients suspected of having swallowing disorders, could highly benefit from simple diagnostic screening before being referred to specialist evaluations. The article analyzes various instrumental methods of dysphagia assessment, introduces surface electromyography (sEMG) to carry out rapid assessment of such patients, and debates proposed suggestions for sEMG screening protocol in order to identify abnormal deglutition. Data sources Subject related books and articles from 1813 to 2007 were obtained through library search, MEDLINE (1949–2007) and EMBASE (1975–2007). Methods Specifics steps for establishing the protocol for applying the technique for screening purposes (e.g., evaluation of specific muscles), the requirements for diagnostic sEMG equipment, the sEMG technique itself, and defining the tests suitable for assessing deglutition (e.g., saliva, normal, and excessive swallows and uninterrupted drinking of water) are presented in detail. SEMG is compared with other techniques in terms of cost, timing, involvement of radiation, etc. Results According to the published data, SEMG of swallowing is a simple and reliable method for screening and preliminary differentiation among dysphagia and odynophagia of various origins. This noninvasive radiation-free examination has a low level of discomfort, and is simple, time-saving and inexpensive to perform. The major weakness of the method seems to be inability for precise diagnostic of neurologically induced dysphagia. Conclusion With standardization of the technique and an established normative database, sEMG might serve as a reliable screening method for optimal patient management but cannot serve for proper investigation of neurogenic dysphagia.

2008-01-01

To evaluate the efficacy of botulinum toxin (BTX-A) injection in the cricopharyngeus muscle in patients with neurological dysphagia caused by alteration in the upper esophageal sphincter (UES) opening and with preserved pharyngeal contraction. A prospective pilot study was undertaken in 10 patients (7 brain lesions and 3 cervical spinal cord injuries), with a minimum time-lapse of 6 months from neurological lesion to BTX-A injection. Dysfunction of the UES opening and the presence of pharyngeal contraction were diagnosed by videofluoroscopy (VDF) and esophageal manometry (EM). The BTX-A (100 U) injection was guided by endoscopy. Clinical, VDF, and EM follow-ups were carried out at 3 weeks, 3 and 6 months, and at 1 year post-injection. Prior to treatment, 6 patients were fed by nasogastric tube. VDF showed impairment of the UES opening, residue in pyriform sinuses, and aspiration in all cases. During follow-up, there was a decrease in the number of patients that had aspiration: 3 patients at one year. During swallowing, EM showed a mean UES relaxation of 90% (range: 74.5-100%), residual pressure 3.2 mmHg (range: 0-13 mmHg) and pharyngeal amplitude 52 mmHg (range: 25-80 mmHg). At follow-up, a significant improvement in UES relaxation (98% (89-100%)) and pharyngeal contraction (97 mmHg (35-165 mmHg)) was observed. At 3 months, 6 patients were eating exclusively by mouth. One single injection of BTX-A in the UES has long-lasting effectiveness in patients with neurological dysphagia caused by alteration in the UES opening and with pharyngeal contraction. Nevertheless, a randomized control trial should be done to confirm these results and rule out the effect of potential spontaneous improvement of neurological injury.

Dysphagia is very common in children with neurological disabilities. These patients usually suffer from respiratory and nutritional problems. The videofluoroscopic swallowing study (VFSS) is the most recommended test to evaluate dysphagia, as it shows the real situation during swallowing. To analyse the results obtained in our centre after one year of the implementation of VFSS, the clinical improvement after confirmation, and the prescription of an individualised treatment for the patients affected. VFSS performed in the previous were collected. The following variables were analysed: age, pathology, degree of neurological damage, oral and pharyngeal and/or oesophageal dysphagia and its severity, aspirations, prescribed treatment, and nutritional and respiratory improvement after diagnosis. A statistical analysis was performed using SPSS v21. A total of 61 VFSS were performed. Dysphagia was detected in more than 70%, being moderate-severe in 58%. Aspirations and/or penetrations were recorded in 59%, of which 50% were silent. Adapted diet was prescribed to 56%, and gastrostomy was performed on 13 (21%) patients. A statistical association was found between neurological disease and severity of dysphagia. The degree of motor impairment is related to the presence of aspirations. After VFSS evaluation and treatment adjustment, nutritional improvement was found in Z-score of weight (+0.3SD) and BMI (+0.4SD). There was respiratory improvement in 71% of patients with dysphagia being controlled in the Chest Diseases Department. After implementation of VFSS, a high percentage of patients were diagnosed and benefited from a correct diagnosis and treatment. VFSS is a fundamental diagnostic test that should be included in paediatric centres as a diagnostic method for children with suspected dysphagia. Copyright © 2017.

2016-01-01

Objective To determine the effects of cervical kyphosis on the recovery of swallowing function in subacute stroke patients. Methods Baseline and 1-month follow-up videofluoroscopic swallowing studies (VFSSs) of 51 stroke patients were retrospectively analyzed. The patients were divided into the cervical kyphosis (Cobb's angle <20°, n=27) and control (n=24) groups. The penetration-aspiration scale (PAS), American Speech-Language-Hearing Association National Outcomes Measurement System swallowing scale (ASHA NOMS), and videofluoroscopic dysphagia scale (VDS) were used to determine the severity of dysphagia. Finally, the prevalence of abnormal VFSS findings was compared between the two groups. Results There were no significant differences in baseline PAS, ASHA NOMS, and VDS scores between the two groups. However, the follow-up VDS scores in the cervical kyphosis group were significantly higher than those in the control group (p=0.04), and a follow-up study showed a tendency towards worse ASHA NOMS scores (p=0.07) in the cervical kyphosis group. In addition, the cervical kyphosis group had a higher occurrence of pharyngeal wall coating in both baseline and follow-up studies, as well as increased aspiration in follow-up studies (p<0.05). Conclusion This study showed that stroke patients who had cervical kyphosis at the time of stroke might have impaired recovery from dysphagia after stroke. PMID:27847711

The pharynx is a locus of provocation among infants with aerodigestive morbidities manifesting as dysphagia, life-threatening events, aspiration-pneumonia, atelectasis, and reflux, and such infants often receive nasal respiratory support. We determined the impact of different oxygen delivery methods on pharyngeal stimulation-induced aerodigestive reflexes [room air (RA), nasal cannula (NC), and nasal continuous positive airway pressure (nCPAP)] while hypothesizing that the sensory motor characteristics of putative reflexes are distinct. Thirty eight infants (28.0 ± 0.7 wk gestation) underwent pharyngoesophageal manometry and respiratory inductance plethysmography to determine the effects of graded pharyngeal stimuli (n = 271) on upper and lower esophageal sphincters (UES, LES), swallowing, and deglutition-apnea. Comparisons were made between NC (n = 19), nCPAP (n = 9), and RA (n = 10) groups. Importantly, NC or nCPAP (vs. RA) had: 1) delayed feeding milestones (P < 0.05), 2) increased pharyngeal waveform recruitment and duration, greater UES nadir pressure, decreased esophageal contraction duration, decreased distal esophageal contraction amplitude, and decreased completely propagated esophageal peristalsis (all P < 0.05), and 3) similarly developed UES contractile and LES relaxation reflexes (P > 0.05). We conclude that aerodigestive reflexes were similarly developed in infants using noninvasive respiratory support with adequate upper and lower aerodigestive protection.

The pharynx is a locus of provocation among infants with aerodigestive morbidities manifesting as dysphagia, life-threatening events, aspiration-pneumonia, atelectasis, and reflux, and such infants often receive nasal respiratory support. We determined the impact of different oxygen delivery methods on pharyngeal stimulation-induced aerodigestive reflexes [room air (RA), nasal cannula (NC), and nasal continuous positive airway pressure (nCPAP)] while hypothesizing that the sensory motor characteristics of putative reflexes are distinct. Thirty eight infants (28.0 ± 0.7 wk gestation) underwent pharyngoesophageal manometry and respiratory inductance plethysmography to determine the effects of graded pharyngeal stimuli (n = 271) on upper and lower esophageal sphincters (UES, LES), swallowing, and deglutition-apnea. Comparisons were made between NC (n = 19), nCPAP (n = 9), and RA (n = 10) groups. Importantly, NC or nCPAP (vs. RA) had: 1) delayed feeding milestones (P < 0.05), 2) increased pharyngeal waveform recruitment and duration, greater UES nadir pressure, decreased esophageal contraction duration, decreased distal esophageal contraction amplitude, and decreased completely propagated esophageal peristalsis (all P < 0.05), and 3) similarly developed UES contractile and LES relaxation reflexes (P > 0.05). We conclude that aerodigestive reflexes were similarly developed in infants using noninvasive respiratory support with adequate upper and lower aerodigestive protection. Increased concern for GERD is unfounded in this population. These infants may benefit from targeted oromotor feeding therapies and safe pharyngeal bolus transit to accelerate feeding milestones.

Background Pharyngeal pH probes and pH-impedance catheters have been developed for the diagnosis of laryngo-pharyngeal reflux. Objective To determine the reliability of pharyngeal pH alone for the detection of pharyngeal reflux events. Methods 24-h pH-impedance recordings performed in 45 healthy subjects with a bifurcated probe for detection of pharyngeal and oesophageal reflux events were reviewed. Pharyngeal pH drops to below 4 and 5 were analysed for the simultaneous occurrence of pharyngeal reflux, gastro-oesophageal reflux, and swallows, according to impedance patterns. Results Only 7.0% of pharyngeal pH drops to below 5 identified with impedance corresponded to pharyngeal reflux, while 92.6% were related to swallows and 10.2 and 13.3% were associated with proximal and distal gastro-oesophageal reflux events, respectively. Of pharyngeal pH drops to below 4, 13.2% were related to pharyngeal reflux, 87.5% were related to swallows, and 18.1 and 21.5% were associated with proximal and distal gastro-oesophageal reflux events, respectively. Conclusions This study demonstrates that pharyngeal pH alone is not reliable for the detection of pharyngeal reflux and that adding distal oesophageal pH analysis is not helpful. The only reliable analysis should take into account impedance patterns demonstrating the presence of pharyngeal reflux event preceded by a distal and proximal reflux event within the oesophagus.

Japan has entered an era of a super-aging population, and given the importance of oral nutrition, the need to evaluate swallowing function has increased. Herein, we contribute to continued developments in evaluating eating and swallowing functions by describing current videoendoscopy (VE) usage and trends to evaluate and diagnose causes of dysphagia. In all, 100 patients (58 men and 42 women; mean age: 79 years) with suspected dysphagia were enrolled; 15 of these were re-examinations. Examinations were conducted according to the Japanese Society of Dysphagia Rehabilitation VE examination guidelines for swallowing. In this study, several patients (77.8 %) with poor vocalization and a saliva reservoir were unable to eat. While evaluating the relationship between aspiration and pharyngeal or laryngeal influx, we found that when pharyngeal and laryngeal influx were present, the risk of aspiration was high. Some patients (38.9 %) were able to eat despite lacking a cough reflex; thus, the absence of a cough reflex does not necessarily equate to an inability to eat, even in patients unable to ingest nutrition orally. One case could ingest nutrition, even with no cough reflex. The 6-month survival rate after the examination of patients on nil per os status was 57.1 %, specifically in patients unable to ingest nutrition orally. These results suggest that decreased eating and swallowing functions indicate a poor prognosis for the patient's quality of life, as eating and swallowing require smooth passage in the oral phase. Therefore, actively requesting a dental intervention and oral rehabilitation is important for a patient presenting these issues.

Pharyngeal-provocation induced aerodigestive symptoms in infants remain an enigma. Sources of pharyngeal provocation can be anterograde as with feeding, and retrograde as in gastroesophageal reflux. We determined maturational and dose-response effects of targeted pharyngeal-stimulus on frequency, stability, and magnitude of pharyngeal and respiratory waveforms during multiple pharyngeal swallowing responses in preterm-born infants when they were of full-term postmenstrual age (PMA). Eighteen infants (11 male) were studied longitudinally at 39.8 ± 4.8 weeks PMA (time-1) and 44.1 ± 5.8 weeks PMA (time-2). Infants underwent concurrent pharyngo-esophageal manometry, respiratory inductance plethysmography, and nasal airflow thermistor methods to test sensory-motor interactions between the pharynx, esophagus, and airway. Linear mixed models were used and data presented as mean ± SEM or %. Overall, responses to 250 stimuli were analyzed. Of the multiple pharyngeal swallowing responses (n = 160), with maturation (a) deglutition apnea duration decreases (p < 0.01), (b) number of pharyngeal waveform peaks and duration decreases for initial responses (p < 0.01), and subsequent responses have lesser variation and greater stability (p < 0.01). With increment in stimulus volumes we noted (a) increased prevalence (%) of pharyngeal responses (p < 0.05), (b) increased number of pharyngeal peaks (p < 0.05), yet pharyngeal frequency (Hz), variability, and stability remain unaffected (p > 0.05), and (c) respiratory changes were unaffected (p > 0.05). Initial and subsequent pharyngeal responses and respiratory rhythm interactions become more distinct with maturation. Interval oromotor experiences and volume-dependent increase in adaptive responses may be contributory. These mechanisms may be important in modulating and restoring respiratory rhythm normalcy.

Diagnosis of pharyngeal dysphagia caused by myasthenia gravis (MG) based on clinical examination alone is often challenging. Flexible endoscopic evaluation of swallowing (FEES) combined with Tensilon (edrophonium) application, referred to as the FEES-Tensilon Test, was developed to improve diagnostic accuracy and to detect the main symptoms of pharyngeal dysphagia in MG. Here we investigated inter- and intra-rater reliability of the FEES-Tensilon Test and analyzed the main endoscopic findings. Four experienced raters reviewed a total of 20 FEES-Tensilon-Test videos in randomized order. Residue severity was graded at 4 different pharyngeal spaces before and after Tensilon administration. All interpretations were performed twice per rater, 4 weeks apart (a total of 160 scorings). Intra-rater test-retest reliability and inter-rater reliability levels were calculated. The most frequent FEES findings in MG patients before Tensilon application were prominent residues of semi solids spread all over the hypopharynx in varying locations. The reliability level in the interpretation of the FEES-Tensilon test was excellent regardless of the raters' profession or years of experience with FEES. All 4 raters showed high inter- and intra- reliability levels in interpreting the FEES-Tensilon Test based on residue clearance (kappa=0.922, 0.981). Degree of residue normalization in the vallecular space after Tensilon application showed the highest inter- and intra-rater reliability level (kappa=0.863, 0.957) followed by the epiglottis (kappa=0.813, 0.946) and pyriform sinuses (kappa=0.836, 0.929). Interpretation of the FEES-Tensilon Test based on residue severity and degree of Tensilon clearance, especially in the vallecular space, is consistent and reliable.

Objective To investigate the effect of low-frequency repetitive transcranial magnetic stimulation (rTMS) and neuromuscular electrical stimulation (NMES) on post-stroke dysphagia. Methods Subacute (<3 months), unilateral hemispheric stroke patients with dysphagia were randomly assigned to the conventional dysphagia therapy (CDT), rTMS, or NMES groups. In rTMS group, rTMS was performed at 100% resting motor threshold with 1 Hz frequency for 20 minutes per session (5 days per week for 2 weeks). In NMES group, electrical stimulation was applied to the anterior neck for 30 minutes per session (5 days per week for 2 weeks). All three groups were given conventional dysphagia therapy for 4 weeks. We evaluated the functional dysphagia scale (FDS), pharyngeal transit time (PTT), the penetration-aspiration scale (PAS), and the American Speech-Language Hearing Association National Outcomes Measurement System (ASHA NOMS) swallowing scale at baseline, after 2 weeks, and after 4 weeks. Results Forty-seven patients completed the study; 15 in the CDT group, 14 in the rTMS group, and 18 in the NMES group. Mean changes in FDS and PAS for liquid during first 2 weeks in the rTMS and NMES groups were significantly higher than those in the CDT group, but no significant differences were found between the rTMS and NMES group. No significant difference in mean changes of FDS and PAS for semi-solid, PTT, and ASHA NOMS was observed among the three groups. Conclusion These results indicated that both low-frequency rTMS and NMES could induce early recovery from dysphagia; therefore, they both could be useful therapeutic options for dysphagic stroke patients.

The intricate mechanism of swallowing can be divided into three phases: oral, pharyngeal, and esophageal. Dysphagia is a disruption in the swallowing process, which include difficulty in transporting (or a lack of transporting) a food or liquid bolus from the mouth through the pharynx and esophagus into the stomach. Causes of disruptions in the swallowing process can be divided into superior (oropharyngeal) and inferior (esophageal) according to Paradowski et al. Neurlologic dysphagia may be caused by a disruption in different parts of the central nervous system (supranuclear level, level of motor and sensory nuclei taking part in swallowing process, peripherial nerves level and a pathology of muscle cells and spindles) or neuromuscular and muscular disorders. Neuromuscular disorders causes according to Waśko-Czopnik et al. are: stroke, brain tumors, brain injury, bulbar and pseudobulbar paralysis, neurodegenerative diseases (amyotrophic lateral sclerosis, multiple sclerosis), tabes dorsalis, multisystem degenerations, Parkinson's disease, delayed dyskineses, Huntington's disease, myasthenia and myasthenic syndromes, myopathies and peripherial neuropathies. The correct diagnosis evaluation include history taking, physical examination with palpation and consultations (laryngological, gastrological and neurological). According to Halama radiological esophagogram, videofluoroscopy, flexible endoscopic examination, ultrasound examination, manometry, electromyography, scintigraphy and 24 hour pH monitoring are main diagnostic procedures of dysphagia. Some of the reasons for the neurologic dysphagia may be treated by surgical and pharmacological methods. Neurologic dysphagia rehabilitation is difficult, long-lasting and often falling far short of expected results. Primary it should include neurologic cause treatment if it is possible. According to WHO International Classification of Functioning and Health in 2001 non-invasive methods of dysphagia treatment may be

Determining the anatomic and functional origin for dysphagia is critical for development of an appropriate therapeutic plan and determination of the prognosis. The purpose of this retrospective study was to report the quantitative and qualitative outcome of contrast videofluoroscopic swallowing studies in a large cohort of dysphagic dogs presenting to a tertiary veterinary care hospital. The videofluoroscopic swallowing studies were reviewed to generate values for pharyngeal constriction ratio, timing of swallowing events (maximum pharyngeal contraction, opening of upper esophageal sphincter, closing of upper esophageal sphincter, and reopening of epiglottis), type of esophageal peristalsis generated, and esophageal transit time. One or more anatomic locations for origin of dysphagia were assigned (pharyngeal, cricopharyngeal, esophageal (primary motility disorder), other esophageal (stricture, vascular ring anomaly, mass), lower esophageal sphincter/hiatus. Sixty-one of 216 studies (28%) were deemed unremarkable. Twenty-seven of 216 dogs (13%) had pharyngeal dysphagia, 17/216 dogs (8%) had cricopharyngeal dysphagia, 98/216 dogs (45%) had dysphagia secondary to esophageal dysmotility, 19/216 dogs (9%) had dysphagia secondary to focal esophageal disorders, and 97/216 dogs (45%) had dysphagia of lower esophageal sphincter/hiatus origin. Multiple abnormalities were present in 82/216 (38%) dogs. Elevated pharyngeal constriction ratio was associated with pharyngeal, cricopharyngeal, and esophageal motility disorders, delayed upper esophageal sphincter opening was associated with cricopharyngeal disorders, a lower percentage of primary esophageal peristaltic waves was associated with cricopharyngeal, pharyngeal, or primary esophageal motility disorders. In conclusion, videofluoroscopic swallowing studies was pivotal in the diagnosis of dysphagia with 155/216 (72%) dogs receiving a final diagnosis. © 2017 American College of Veterinary Radiology.

Gastrostomy feeding tubes are commonly placed in patients with dysphagia after stroke. The subsequent removal of the tube is a primary goal during rehabilitation. The purpose of our review was to identify predictors and factors associated with gastrostomy tube removal in patients with dysphagia after stroke. We conducted a literature review following the PRISMA statement and included the search databases PubMed, Scopus, Web of Science, and CINAHL. Articles were included in the final analysis per predefined inclusion and exclusion criteria. Our search retrieved a total of 853 results consisting of 416 articles (after eliminating duplicates). Six articles met our final eligibility criteria. The following factors were identified in at least 1 article as being significantly associated with gastrostomy tube removal: reduced age, decreased number of comorbidities, prolonged inpatient rehabilitation stay, absence of bilateral stroke, nonhemorrhagic stroke, reduced dysphagia severity, absence of aspiration, absence of premature bolus loss, and timely initiation of pharyngeal swallow. Aspiration was the only factor that was investigated by 2 studies-both using multiple regression and both showing stable results, with absence of aspiration increasing the chances for tube removal. In conclusion, little is known about factors associated with gastrostomy tube removal in patients with dysphagia after stroke. Most of the identified factors are associated with stroke or disease severity; however, the role of the individual factors remains unclear. The strongest predictor appears to be absence of aspiration on modified barium swallow studies emphasizing the importance of instrumental swallow studies in this patient population.

The pharyngeal muscles of the nasal, oral, and laryngeal pharynxes are required for swallowing. Pharyngeal muscles are preferentially affected in some muscular dystrophies yet spared in others. Muscle stem cells, called satellite cells, may be critical factors in the development of pharyngeal muscle disorders; however, very little is known about pharyngeal satellite cells (PSC) and their role in pharyngeal muscles. We show that PSC are distinct from the commonly studied hindlimb satellite cells both transcriptionally and biologically. Under basal conditions PSC proliferate, progress through myogenesis, and fuse with pharyngeal myofibers. Furthermore, PSC exhibit biologic differences dependent on anatomic location in the pharynx. Importantly, PSC are required to maintain myofiber size and myonuclear number in pharyngeal myofibers. Together, these results demonstrate that PSC are critical for pharyngeal muscle maintenance and suggest that satellite cell impairment could contribute to pharyngeal muscle pathology associated with various muscular dystrophies and aging.

To determine changes in prevalence and severity of oropharyngeal dysphagia (OPD) in children with cerebral palsy (CP) and the relationship to health outcomes. Longitudinal cohort study. Community and tertiary institutions. Children (N=53, 33 boys) with a confirmed diagnosis of CP assessed first at 18 to 24 months (Assessment 1: mean age ± SD, 22.9±2.9 mo corrected age; Gross Motor Function Classification System [GMFCS]: I, n=22; II, n=7; III, n=11; IV, n=5; V, n=8) and at 36 months (Assessment 2). Not applicable. OPD was classified using the Dysphagia Disorders Survey (DDS) and signs suggestive of pharyngeal dysphagia. Nutritional status was measured using Z scores for weight, height, and body mass index (BMI). Gross motor skills were classified on GMFCS and motor type/distribution. Prevalence of OPD decreased from 62% to 59% between the ages of 18 to 24 months and 36 months. Thirty percent of children had an improvement in severity of OPD (greater than smallest detectable change), and 4% had worse OPD. Gross motor function was strongly associated with OPD at both assessments, on the DDS (Assessment 1: odds ratio [OR]=20.3, P=.011; Assessment 2: OR=28.9, P=.002), pharyngeal signs (Assessment 1: OR=10.6, P=.007; Assessment 2: OR=15.8, P=.003), and OPD severity (Assessment 1: β=6.1, P<.001; Assessment 2: β=5.5, P<.001). OPD at 18 to 24 months was related to health outcomes at 36 months: low Z scores for weight (adjusted β=1.2, P=.03) and BMI (adjusted β=1.1, P=.048), and increased parent stress (adjusted OR=1.1, P=.049). Classification and severity of OPD remained relatively stable between 18 to 24 months and 36 months. Gross motor function was the best predictor of OPD. These findings contribute to developing more effective screening processes that consider critical developmental transitions that are anticipated to present challenges for children from each of the GMFCS levels.

Summary 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.

Recently, many medical professionals become to realize eating problem affect deeply patient's quality of life (QOL), and they are very interested in dysphagia rehabilitation. I overviewed dysphagia rehabilitation along with the followings; (1) impact of dysphagia, (2) assessment of dysphagia, and (3) management of dysphagia. Eating is the most enjoyable activity. Dysphagia changes this enjoyable activity to the most fearful one. Dysphagia makes three major problems: risk of aspiration pneumonia and suffocation, risk of dehydration and malnutrition, and depriving enjoyable activity. As a recent conceptualization of eating, the Process model is the most important, that reveals eating (chew-swallow) is very different from just chewing plus swallowing in physiologically. In assessment, standardized functional tests such as the Repetitive saliva swallowing test, the Modified water swallowing test, and the Graded food test are used. The most important point in clinical assessment is identifying indication of direct therapy using food or starting period of oral feeding. Videofluorographic and videoendoscopic examinations are used as precise diagnostic and management-oriented assessment tools. In management, exercise, posture adjustment, and modification of food promote eating possibility. Oral care is essential in dysphagic patients. Surgical intervention is effective method if a patient has severe dysphagia.

We set out to ascertain the evolution and the clinical and videofluoroscopic (VFS) prognostic factors of aspiration recovery and return to oral intake in patients with stroke and VFS diagnosis of tracheal aspiration. Twenty patients with stroke and VFS diagnosis of tracheal aspiration were prospectively evaluated. Clinical evaluation of oropharyngeal dysphagia and VFS examination were performed at admission and repeated at 1, 3, 6 and 12 months of follow-up. At admission, videofluoroscopy showed 40% of patients to have an increase in oral transit time and 65% impaired tongue control; in the pharyngeal phase, mean pharyngeal transit time was increased in 70% of patients and the time required to trigger the swallowing reflex was delayed in 70%. During follow-up, an improvement was observed, and the number of patients with aspiration decreased progressively (the most significant change occurred at 6 months). Evolution was related to the vascular territory affected: at 1 year, aspiration persisted in 12% of anterior territory lesions vs. 58% of posterior territory lesions. Also, the number of silent aspirators decreased from 35% at baseline to no patients after 3 months. Persistent aspiration at 1 year of follow-up significantly correlated with the following baseline variables: vascular territory, gag reflex abolition, palatoglossal seal alteration and pharyngeal delay time. Swallowing physiology in stroke greatly improved during follow-up, mainly between 3 and 6 months, and the number of aspirations decreased progressively. Prognostic factors for persisting aspiration are posterior vascular territory lesions, oropharyngeal reflex abolition, palatoglossal seal alteration and pharyngeal delay time at baseline.

Postoperative throat complaints such as postoperative sore throat (POST), dysphagia, and hoarseness frequently arises after tracheal intubation and throat packing for patient undergoing general anesthesia. This condition is very disturbing to patient. Avoiding POST is a major priority for these patients because preventing postoperative complications contributes to patient satisfaction. To describe and analyze the postoperative throat effects of nasopharyngeal packing and oropharyngeal packing in patients undergoing nasal surgery. A randomized comparative study. After obtaining approval of Ethical Committee 40 patients were included in study. After this patient were randomly allocated into two groups of 20 each. Group A - in which the oropharynx was packed and Group B - inwhich the nasopharynx was packed. General anesthesia were given and throat packing was done and patients were interviewed postoperatively for any throat complications such as sore throat, difficulty in swallowing (dysphagia), hoarseness of voice, throat irritation, and any other symptom pertaining to the study were noted and data were analyzed. T-test to compare the age, while Chi-square test and Fisher's exact test were used to compare sex distribution, sore throat, dysphagia, hoarseness, and throat irritation. Results showed statistically significant difference in incidence and severity of POST in Group A patients when compared to Group B patients to be more. Patients in Group A had a higher incidence of dysphagia when compared to their Group B counterparts. With respect to the incidence of hoarseness and throat irritation, there was no statistical significance between the groups. We concluded that the site of pharyngeal packing influences the incidence and severity of POST and as well as the incidence of dysphagia after general anesthesia. The use of nasopharyngeal packing in the patients undergoing nasal surgeries might lead to a reduction of the same.

Objective To investigate swallowing laterality in hemiplegic patients with stroke and recovery of dysphagia according to the laterality. Method The sample was comprised of 46 dysphagic patients with hemiplegia after their first stroke. The sample's videofluoroscopic swallowing study (VFSS) was reviewed. Swallowing laterality was determined by the anterior-posterior view of VFSS. We measured width difference of barium sulfate liquid flow in the pharyngoesophageal segment. If there was double or more the width of that from the opposite width in the pharyngoesophageal segment more than twice on three trials of swallowing, then it was judged as having laterality. Subjects were assigned to no laterality (NL), laterality that is ipsilateral to hemiplegic side (LI), and laterality that is contralateral to hemiplegic side (LC) groups. We measured the following: prevalence of aspiration, the 8-point penetration-aspiration scale, and the functional dysphagia scale of the subjects at baseline and follow up. Results Laterality was observed in 45.7% of all patients. Among them, 52.4% were in the hemiplegic direction. There was no significant difference between groups at baseline in all measurements. When we compared the changes in all measurements on follow-up study, there were no significant differences between groups. Conclusion Through this study, we found that there was no significant relation between swallowing laterality and the severity or prognosis of swallowing difficulty. More studies for swallowing laterality on stroke patients will be needed. PMID:23185735

Dysphagia is very common in patients with Parkinson disease (PD) and often leads to aspiration pneumonia, the most common cause of death in PD. Current therapies are largely ineffective for dysphagia. Because pharyngeal sensation normally triggers the swallowing reflex, we examined pharyngeal sensory nerves in PD patients for Lewy pathology.Sensory nerves supplying the pharynx were excised from autopsied pharynges obtained from patients with clinically diagnosed and neuropathologically confirmed PD (n = 10) and healthy age-matched controls (n = 4). We examined the glossopharyngeal nerve (cranial nerve IX), the pharyngeal sensory branch of the vagus nerve (PSB-X), and the internal superior laryngeal nerve (ISLN) innervating the laryngopharynx. Immunohistochemistry for phosphorylated α-synuclein was used to detect Lewy pathology. Axonal α-synuclein aggregates in the pharyngeal sensory nerves were identified in all of the PD subjects but not in the controls. The density of α-synuclein-positive lesions was greater in PD patients with dysphagia versus those without dysphagia. In addition, α-synuclein-immunoreactive nerve fibers in the ISLN were much more abundant than those in cranial nerve IX and PSB-X. These findings suggest that pharyngeal sensory nerves are directly affected by pathologic processes in PD. These abnormalities may decrease pharyngeal sensation, thereby impairing swallowing and airway protective reflexes and contributing to dysphagia and aspiration.

Streptococcal acute pharyngitis.

Acute pharyngitis/tonsillitis, which is characterized by inflammation of the posterior pharynx and tonsils, is a common disease. Several viruses and bacteria can cause acute pharyngitis; however, Streptococcus pyogenes (also known as Lancefield group A β-hemolytic streptococci) is the only agent that requires an etiologic diagnosis and specific treatment. S. pyogenes is of major clinical importance because it can trigger post-infection systemic complications, acute rheumatic fever, and post-streptococcal glomerulonephritis. Symptom onset in streptococcal infection is usually abrupt and includes intense sore throat, fever, chills, malaise, headache, tender enlarged anterior cervical lymph nodes, and pharyngeal or tonsillar exudate. Cough, coryza, conjunctivitis, and diarrhea are uncommon, and their presence suggests a viral cause. A diagnosis of pharyngitis is supported by the patient's history and by the physical examination. Throat culture is the gold standard for diagnosing streptococcus pharyngitis. However, it has been underused in public health services because of its low availability and because of the 1- to 2-day delay in obtaining results. Rapid antigen detection tests have been used to detect S. pyogenes directly from throat swabs within minutes. Clinical scoring systems have been developed to predict the risk of S. pyogenes infection. The most commonly used scoring system is the modified Centor score. Acute S. pyogenes pharyngitis is often a self-limiting disease. Penicillins are the first-choice treatment. For patients with penicillin allergy, cephalosporins can be an acceptable alternative, although primary hypersensitivity to cephalosporins can occur. Another drug option is the macrolides. Future perspectives to prevent streptococcal pharyngitis and post-infection systemic complications include the development of an anti-Streptococcus pyogenes vaccine.

The study aim was to document the acute physiological characteristics of swallowing impairment following thermal burn injury. A series of 19 participants admitted to a specialised burn centre with thermal burn injury were identified with suspected aspiration risk by a clinical swallow examination (CSE) conducted by a speech-language pathologist and referred to the study. Once medically stable, each then underwent more detailed assessment using both a CSE and fiberoptic evaluation of swallowing (FEES). FEES confirmed six individuals (32%) had no aspiration risk and were excluded from further analyses. Of the remaining 13, CSE confirmed that two had specific oral-phase deficits due to orofacial scarring and contractures, and all 13 had generalised oromotor weakness. FEES revealed numerous pharyngeal-phase deficits, with the major findings evident in greater than 50% being impaired secretion management, laryngotracheal edema, delayed swallow initiation, impaired sensation, inadequate movement of structures within the hypopharynx and larynx, and diffuse pharyngeal residue. Penetration and/or aspiration occurred in 83% (n = 10/12) of thin fluids trials, with a lack of response to the penetration/aspiration noted in 50% (n = 6/12 penetration aspiration events) of the cases. Most events occurred post swallow. Findings support the fact that individuals with dysphagia post thermal burn present with multiple risk factors for aspiration that appear predominantly related to generalised weakness and inefficiency and further impacted by edema and sensory impairments. Generalised oromotor weakness and orofacial contractures (when present) impact oral-stage swallow function. This study has identified a range of factors that may contribute to both oral- and pharyngeal-stage dysfunction in this clinical population and has highlighted the importance of using a combination of clinical and instrumental assessments to fully understand the influence of burn injury on oral intake and

Objective To investigate immediate changes in hyolaryngeal movement and swallowing function after a cycle of neuromuscular electrical stimulation (NMES) on both submental and throat regions and submental placement alone in patients with dysphagia. Methods Fifteen patients with dysphagia were recruited. First, videofluoroscopic swallowing study (VFSS) was performed before NMES. All patients thereafter received a cycle of NMES by 2 methods of electrode placement: 1) both submental and throat regions and 2) submental placement alone concomitant with VFSS. The Penetration-Aspiration Score (PAS) and the NIH-Swallowing Safety Scale (NIH-SSS) were measured for swallowing function. Results During swallowing, hyolaryngeal descent significantly occurred by NMES on both submental and throat regions, and anterior displacement of hyolaryngeal complex was significant on submental placement alone. NMES on submental placement alone did not change the PAS and NIH-SSS. However, NMES on both submental and throat regions significantly reduced the NIH-SSS, although it did not change the PAS. Patients with no brainstem lesion and with dysphagia duration of <3 months showed significantly improved the NIH-SSS. Conclusion Immediate hyolaryngeal movement was paradoxically depressed after NMES on both submental and throat regions with significant reductions in the NIH-SSS but not the PAS, suggesting improvement in pharyngeal peristalsis and cricopharyngeal functions at the esophageal entry rather than decreased aspiration and penetration. The results also suggested that patients with dysphagia should be carefully screened when determining motor-level NMES. PMID:25932416

The chin-down posture is generally recommended in patients with neurogenic dysphagia to prevent tracheal aspiration; however, its effectiveness has not been demonstrated. To videofluoroscopically (VDF) assess the effectiveness of chin-down posture to prevent aspiration in patients with neurogenic dysphagia secondary to acquired brain injury. Randomized, alternating, cross-over study (with and without the chin-down posture) in 47 patients with a VDF diagnosis of aspiration [31 stroke, 16 traumatic brain injury (TBI)] and 25 controls without aspiration (14 stroke, 11 TBI). During the chin-down posture, 55% of patients avoided aspiration (40% preswallow aspiration and 60% aspiration during swallow). The percentage was similar in both etiologies (58% stroke and 50% TBI). Fifty-one percent of patients had silent aspiration; of these, 48% persisted with aspiration while in the chin-down posture. A statistically significant relationship was found between the existence of pharyngeal residue, cricopharyngeal dysfunction, pharyngeal delay time and bolus volume with the persistence of aspiration. The chin-down posture did not change swallow biomechanics in patients without aspiration. Only half the patients with acquired brain injury avoided aspiration during cervical flexion; 48% of silent aspirators continued to aspire during the maneuver. Several videofluoroscopic parameters were related to inefficiency of the maneuver. Therefore, the indication for chin-down posture should be evaluated by videofluoroscopic examination. © 2012 Blackwell Publishing Ltd.

Background Dysphagia is associated with aspiration, pneumonia and malnutrition, but remains challenging to identify at the bedside. A variety of exam protocols and maneuvers are commonly used, but the efficacy of these maneuvers is highly variable. Methods We conducted a comprehensive search of seven databases, including MEDLINE, EMBASE and Scopus, from each database’s earliest inception through June 5th, 2013. Studies reporting diagnostic performance of a bedside examination maneuver compared to a reference gold standard (videofluoroscopic swallow study [VFSS] or flexible endoscopic evaluation of swallowing with sensory testing [FEEST]) were included for analysis. From each study, data were abstracted based on the type of diagnostic method and reference standard study population and inclusion/exclusion characteristics, design and prediction of aspiration. Results The search strategy identified 38 articles meeting inclusion criteria. Overall, most bedside examinations lacked sufficient sensitivity to be used for screening purposes across all patient populations examined. Individual studies found dysphonia assessments, abnormal pharyngeal sensation assessments, dual axis accelerometry, and one description of water swallow testing to be sensitive tools, but none were reported as consistently sensitive. A preponderance of identified studies was in post-stroke adults, limiting the generalizability of results. Conclusions No bedside screening protocol has been shown to provide adequate predictive value for presence of aspiration. Several individual exam maneuvers demonstrated reasonable sensitivity, but reproducibility and consistency of these protocols was not established. More research is needed to design an optimal protocol for dysphagia detection. PMID:25581840

Bremke, M; Wagner, H-J; Folz, B J

Diffuse idiopathic skeletal hyperostosis (DISH) may lead to dysphagia caused by osteophytes of the cervical spine. Osteophytes can be resected transorally or transcervically, but operative ablation should not be indicated generously because of the threat of severe complications. A fifty-year-old man with dysphagia and loss of weight of 15 kg in the last three months is presented. He also suffered from a brain damage during infancy which caused grand-mal-seizures. One seizure lead to cardiac arrest which required cardio-pulmonary resuscitation and subsequent tracheostomy. A spheric tumor of the posterior pharyngeal wall could be seen endoscopically, it appeared radiologically as an osteophytic formation of the segments C (3) - C (5). Ossification of the anterior longitudinal ligament was also seen. Diagnosis of DISH was made on the basis of these results. Contrast imaging of the esophagus and videofluoroscopy showed aspiration in terms of neurogenic disorders. The patient received a percutaneous gastrostomy after his case was discussed with neurologic and orthopaedic colleagues, because a causal therapy of the combined disease seemed to be impossible. Dysphagia in the presented case was caused by a combination of neurogenic deglutition disorders and oropharyngeal obstruction through osteophytes. Surgical removal of the osteophytes was not indicated because it would have put the patient at a certain risk, but only a part of the underlying problem would have been removed. Symptomatic therapy with a gastrostomy secures normocaloric diet. The patient's weight remained stable and he can follow his habitual daily routine.

Dysphagia is very common in patients with Parkinson’s disease (PD) and often leads to aspiration pneumonia, the most common cause of death in PD. Unfortunately, current therapies are largely ineffective for dysphagia. As pharyngeal sensation normally triggers the swallowing reflex, we examined pharyngeal sensory nerves in PD for Lewy pathology. Sensory nerves supplying the pharynx were excised from autopsied pharynges obtained from patients with clinically diagnosed and neuropathologically confirmed PD (n = 10) and healthy age-matched controls (n = 4). We examined: the glossopharyngeal nerve (IX); the pharyngeal sensory branch of the vagus nerve (PSB-X); and the internal superior laryngeal nerve (ISLN) innervating the laryngopharynx. Immunohistochemistry for phosphorylated α-synuclein was used to detect potential Lewy pathology. Axonal α-synuclein aggregates in the pharyngeal sensory nerves were identified in all of the PD subjects but not in the controls. The density of α-synuclein-positive lesions was significantly greater in PD subjects with documented dysphagia compared to those without dysphagia. In addition, α-synuclein-immunoreactive nerve fibers in the ISLN were much more abundant than those in the IX and PSBX. These findings suggest that pharyngeal sensory nerves are directly affected by the pathologic process of PD. This anatomic pathology may decrease pharyngeal sensation impairing swallowing and airway protective reflexes, thereby contributing to dysphagia and aspiration. PMID:23771215

Assessing esophageal dysphagia.

Kruger, Danielle

Dysphagia, or difficulty swallowing, is a common problem. Although most cases are attributable to benign disease processes, dysphagia is also a key symptom in several malignancies, making it an important symptom to evaluate. The differential diagnosis of dysphagia requires an understanding of deglutition, in particular the oropharyngeal versus esophageal stages. Stroke is the leading cause of oropharyngeal dysphagia, which is common in older adults and frequently presents as part of a broader complex of clinical manifestations. In esophageal dysphagia, difficulty swallowing is often the main complaint and is caused by localized neuromuscular disorders or obstructive lesions.

Chemo-IMRT of Oropharyngeal Cancer Aiming to Reduce Dysphagia: Swallowing Organs Late Complication Probabilities and Dosimetric Correlates

Purpose: Assess dosimetric correlates of long-term dysphagia after chemo-intensity-modulated radiotherapy (IMRT) of oropharyngeal cancer (OPC) sparing parts of the swallowing organs. Patients and Methods: Prospective longitudinal study: weekly chemotherapy concurrent with IMRT for Stages III/IV OPC, aiming to reduce dysphagia by sparing noninvolved parts of swallowing-related organs: pharyngeal constrictors (PC), glottic and supraglottic larynx (GSL), and esophagus, as well as oral cavity and major salivary glands. Dysphagia outcomes included patient-reported Swallowing and Eating Domain scores, Observer-based (CTCAEv.2) dysphagia, and videofluoroscopy (VF), before and periodically after therapy through 2 years. Relationships between dosimetric factors and worsening (from baseline) of dysphagia throughmore » 2 years were assessed by linear mixed-effects model. Results: Seventy-three patients participated. Observer-based dysphagia was not modeled because at >6 months there were only four Grade {>=}2 cases (one of whom was feeding-tube dependent). PC, GSL, and esophagus mean doses, as well as their partial volume doses (V{sub D}s), were each significantly correlated with all dysphagia outcomes. However, the V{sub D}s for each organ intercorrelated and also highly correlated with the mean doses, leaving only mean doses significant. Mean doses to each of the parts of the PCs (superior, middle, and inferior) were also significantly correlated with all dysphagia measures, with superior PCs demonstrating highest correlations. For VF-based strictures, most significant predictor was esophageal mean doses (48{+-}17 Gy in patients with, vs 27{+-}12 in patients without strictures, p = 0.004). Normal tissue complication probabilities (NTCPs) increased moderately with mean doses without any threshold. For increased VF-based aspirations or worsened VF summary scores, toxic doses (TDs){sub 50} and TD{sub 25} were 63 Gy and 56 Gy for PC, and 56 Gy and 39 Gy for GSL, respectively

This study compares the outcomes using VitalStim therapy to outcomes using traditional swallowing therapy for deglutition disorders. Twenty-two patients had an initial and a followup videofluoroscopic swallowing study or fiberoptic endoscopic evaluation of swallowing and were divided into an experimental group that received VitalStim treatments and a control group that received traditional swallowing therapy. Outcomes were analyzed for changes in oral and pharyngeal phase dysphagia severity, dietary consistency restrictions, and progression from nonoral to oral intake. Results of chi(2) analysis showed no statistically significant difference in outcomes between the experimental and control groups.

Hirata, Gisela Carmona; Santos, Rosane Sampaio

2012-01-01

Summary Introduction: There are an estimated 30,000–40,000 new cases of cerebral palsy per year in Brazil. Motor disorders caused by cerebral palsy can lead to dysphagia as they may alter the preparatory, oral, pharyngeal, and esophageal phases. Aim: To identify existing rehabilitation methods of swallowing disorders in cerebral palsy, with emphasis on the pursuit of research using the Bobath concept, the Castillo Morales concept, oral sensorimotor therapy, and continuing education. Summary of the findings: We performed a systematic review of the medical and speech therapy literature on the rehabilitation of oropharyngeal dysphagia in children with cerebral palsy spanning 1977–2010 and from all languages and nations. Among the 310 articles retrieved, only 22 (7.09%) addressed therapeutic rehabilitation of oropharyngeal dysphagia in children with cerebral palsy. Of the 22 reports, 12 (54.5%) were from Canada, 3 (13.6%) were from Japan, 2 (9%) were from Brazil, 2 (9%) were from Germany, 1 (4.5%) was from the USA, 1 (4.5%) was from the United Kingdom, and 1 (4.5%) was from Poland. Of these reports, 63.6% used oral sensorimotor therapy as a therapeutic method, 36.3% reported continuing education as a therapeutic approach, and only 18.1% and 9% used the Bobath concept and Castillo Morales concept, respectively. Conclusion: Even with a constantly increasing cerebral palsy population, few studies include (re)habilitation in the treatment of oropharyngeal dysphagia in these children. PMID:25991964

Background Dysphagia is a frequent and dangerous complication of acute stroke. Apart from a well-timed oropharyngeal muscular contraction pattern, sensory feedback is of utmost importance for safe and efficient swallowing. In the present study, we therefore analyzed the relation between pharyngolaryngeal sensory deficits and post-stroke dysphagia (PSD) severity in a cohort of acute stroke patients with middle cerebral artery (MCA) infarction. Methods Eighty-four first-ever MCA stroke patients (41 left, 43 right) were included in this trial. In all patients, fiberoptic endoscopic evaluation of swallowing (FEES) was performed according to a standardized protocol within 96 h after stroke onset. PSD was classified according to the 6-point fiberoptic endoscopic dysphagia severity scale. Pharyngolaryngeal sensation was semi-quantitatively evaluated by a FEES-based touch technique. Results PSD severity was closely related to the pharyngolaryngeal sensory deficit. With regards to lateralization of the sensory deficit, there was a slight but significant preponderance of sensory loss contralateral to the side of stroke. Apart from that, right hemispheric stroke patients were found to present with a more severe PSD. Conclusions This study provides evidence that an intact sensory feedback is of utmost importance to perform nonimpaired swallowing and highlights the key role of disturbed pharyngeal and laryngeal afferents in the pathophysiology of PSD.

Several pathologies, including pharyngitis, are associated with abdominal pain that can mimic appendicitis. We sought to further understand the link between appendicitis-like symptoms and streptococcal (strep) pharyngitis. All patients undergoing ultrasound imaging for appendicitis in our emergency department during 2013 were reviewed (n = 1572). A total of 207 patients were identified who underwent both ultrasound for appendicitis and testing for strep pharyngitis. Demographic and outcomes data between rule out appendicitis patients who underwent strep testing and those who did not were compared. Strep testing was more common in younger patients (mean age = 8.26 vs 10.26 years P < .001) and evenly matched by gender (104 male, 103 female). Of the 207 patients tested for strep pharyngitis, 8 (3.9%) patients had appendicitis and 35 (16.9%) patients tested positive for strep pharyngitis. No cases of concurrent strep pharyngitis and appendicitis were identified. The negative appendectomy rate in the strep pharyngitis tested group was 38.5% (5/13), compared with 7.7% (23/296) ( P = .003) in the nontested group. The appendicitis rate among the strep tested group was 3.8% (8/207) compared with 20% (273/1365) in the nontested group ( P < .001). Patients undergoing testing for strep pharyngitis were younger, had lower rates of appendicitis, and had a higher rate of negative appendectomy. A diagnosis of concurrent appendicitis and strep pharyngitis is rare. In cases of patients with sufficient symptoms to warrant testing for strep pharyngitis a diagnosis of appendicitis is less likely and surgical intervention leads to higher negative appendectomy rates.

To investigate the relationship between content of substance P, VIP in the pharyngeal tissue and narrow pharyngeal cavity of patients with OSAS. By using semi-quantitative immunohistochemical method, resected pharyngeal tissue from 30 patients with OSAS and 12 normal health adult controls were investigated with rabbit anti-substance P and rabbit anti-VIP. SP and VIP were detected in tribution within the epithelium or between epithelium cells, around the pharyngeal glands and gland ducts, around endothelium cells and smooth muscle of blood vessels. SP and VIP levels in pharyngeal tissue of the patients with OSAS were increased than those of the controls. Narrow of pharyngeal cavity with OSAS was relative to edema of pharyngeal tissue induced by increased SP and VIP in pharyngeal tissue. A neurogenic inflammation was one of the factors of OSAS.

The purpose of this study was to compare the effects of a novel neuromuscular electrical stimulation (NMES) to the effects of conventional treatment in patients with dysphagia after brain injury. In total, 26 patients were non-randomly divided into an experimental group (n = 12) and a control group (n = 14). The experimental group received NMES intervention followed by conventional treatment, including thermal-tactile stimulation with intensive repetition of a dry-swallow task. The control group received conventional treatment without NMES. NMES at a fixed pulse duration of 50 μs and a frequency of 50 Hz was delivered over the skin areas above the motor point of the target muscles, i.e., the bilateral geniohyoid, mylohyoid/anterior belly of the digastric, and thyrohyoid muscles, using a high-voltage pulsed-current device. The two groups received 40-min treatments once a day, 5 days per week, for 8 weeks. Outcome, assessed before and 8 weeks after treatment, was evaluated with regard to the videofluoroscopic dysphagia scale (VDS), the anterior and superior displacement of the hyoid bone and larynx, and the functional oral intake scale. Both groups exhibited improvement, but the experimental group exhibited more significant improvement in the displacement of the hyoid bone and larynx, VDS-total score, and VDS-pharyngeal score than the control group did. The results suggest that NMES combined with conventional treatment is superior to conventional treatment alone in patients with dysphagia following treatment for brain injury. Further investigations are necessary to examine the effects of NMES in patients with more varied types of diseases. PMID:24670314

Purpose To assess clinical and functional results of chemoradiotherapy for oropharyngeal cancer (OPC), utilizing intensity-modulated radiotherapy (IMRT) to spare the important swallowing structures to reduce post-therapy dysphagia. Patients and Methods This was a prospective study of weekly chemotherapy (carboplatin dosed at one times the area under the curve [AUC, AUC 1] and paclitaxel 30 mg/m2) concurrent with IMRT aiming to spare noninvolved parts of the swallowing structures: pharyngeal constrictors, glottic and supraglottic larynx, and esophagus as well as the oral cavity and major salivary glands. Swallowing was assessed by patient-reported Swallowing and Eating Domain scores, observer-rated scores, and videofluoroscopy (VF) before therapy and periodically after therapy through 2 years. Results Overall, 73 patients with stages III to IV OPC participated. At a median follow-up of 36 months, 3-year disease-free and locoregional recurrence-free survivals were 88% and 96%, respectively. All measures of dysphagia worsened soon after therapy; observer-rated and patient-reported scores recovered over time, but VF scores did not. At 1 year after therapy, observer-rated dysphagia was absent or minimal (scores 0 to 1) in all patients except four: one who was feeding-tube dependent and three who required soft diet. From pretherapy to 12 months post-therapy, the Swallowing and Eating Domain scores worsened on average (± standard deviation) by 10 ± 21 and 13 ± 19, respectively (on scales of 0 to 100), and VF scores (on scale of 1 to 7) worsened from 2.9 ± 1.5 (mild dysphagia) to 4.1 ± 0.9 (mild/moderate dysphagia). Conclusion Chemoradiotherapy with IMRT aiming to reduce dysphagia can be performed safely for OPC and has high locoregional tumor control rates. On average, long-term patient-reported, observer-rated, and objective measures of swallowing were only slightly worse than pretherapy measures, representing potential improvement compared with previous studies

Kinematic analysis of swallowing function using videofluoroscopic swallowing study (VFSS). The aims of this study were to analyze swallowing process in the patients who underwent occipitospinal fusion (OSF) and elucidate the pathomechanism of dysphagia after OSF. Although several hypotheses about the pathomechanisms of dysphagia after OSF were suggested, there has been little tangible evidence to support these hypotheses since these hypotheses were based on the analysis of static radiogram or CT. Considering that swallowing is a compositive motion of oropharyngeal structures, the etiology of postoperative dysphagia should be investigated through kinematic approaches. Each four patients with or without postoperative dysphagia (group D and N, respectively) participated in this study. For VFSS, all patients were monitored to swallow 5-mL diluted barium solution by fluoroscopy, and then dynamic passing pattern of the barium solution was analyzed. Additionally, O-C2 angle (O-C2A) was measured for the assessment of craniocervical alignment. O-C2A in group D was -7.5 degrees, which was relatively smaller than 10.3 degrees in group N (P = 0.07). In group D, all cases presented smooth medium passing without any obstruction at the upper cervical level regardless of O-C2A, whereas the obstruction to the passage of medium was detected at the apex of mid-lower cervical ocurvature, where the anterior protrusion of mid-lower cervical spine compressed directly the pharyngeal space. In group N, all cases showed smooth passing of medium through the whole process of swallowing. This study presented that postoperative dysphagia did not occur at the upper cervical level even though there was smaller angle of O-C2A and demonstrated the narrowing of the oropharyngeal space towing to direct compression by the anterior protrusion of mid-lower cervical spine was the etiology of dysphagia after OSF. Therefore, surgeon should pay attention to the alignment of mid-cervical spine as well as

To determine whether findings on videofluoroscopic swallow studies reveal different patterns of dysphagia between children with central and peripheral neurologic disorders, a retrospective study of 118 videofluoroscopic swallow studies was completed. There were 3 groups: cerebral palsy with only spastic features (n = 53), cerebral palsy with dyskinetic features (n = 34), and neuromuscular disorders (myotonic dystrophy I, n = 5; spinal muscular atrophy I-II, n = 8; Duchenne muscular dystrophy, n = 8; other neuromuscular disorder, n = 10). Interpretation of the videofluoroscopic swallow studies was not blinded. The video fluoroscopic swallow study findings were compared dichotomously between the groups. Children with cerebral palsy demonstrated dysphagia in 1 or all phases of swallowing. In neuromuscular disorder, muscle weakness results in pharyngeal residue after swallow. The underlying swallowing problem in neuromuscular disorder is muscle weakness whereas that in cerebral palsy is more complex, having to do with abnormal control of swallowing. This study serves as a first exploration on specific characteristics of swallowing in different neurologic conditions and will help clinicians anticipate what they might expect.

The volume-viscosity swallow test for clinical screening of dysphagia and aspiration.

2012-01-01

Oropharyngeal dysphagia (OD) is a major complaint among many patients with neurological diseases and in the elderly, but is often underdiagnosed. The volume-viscosity swallow test (V-VST) is a bedside method to screen patients for dysphagia. The V-VST was designed to identify clinical signs of impaired efficacy (labial seal, oral and pharyngeal residue, and piecemeal deglutition) and impaired safety of swallow (voice changes, cough and decrease in oxygen saturation ≥3%). It starts with nectar viscosity and increasing bolus volume, then liquid and finally pudding viscosity in a progression of increasing difficulty to protect patients from aspiration. The V-VST allows quick, safe and accurate screening for OD in hospitalized and independently living patients with multiple etiologies. The V-VST presents a sensitivity of 88.2% and a specificity of 64.7% to detect clinical signs of impaired safety of swallow (aspiration or penetration). The test takes 5-10 min to complete. The V-VST is an excellent tool to screen patients for OD. It combines good psychometric properties, a detailed and easy protocol designed to protect safety of patients, and valid end points to evaluate safety and efficacy of swallowing and detect silent aspirations.

2016-01-01

Oropharyngeal dysphagia due to upper esophageal sphincter (UES) dysfunction is commonly encountered in the clinical setting. Selective experimental perturbation of various components of the deglutitive apparatus can provide an opportunity to improve our understanding of the swallowing physiology and pathophysiology. The aim is to characterize the pharyngeal and UES deglutitive pressure phenomena in an experimentally induced restriction of UES opening in humans. We studied 14 volunteers without any dysphagic symptoms (7 men, 66 ± 11 yr) but with various supraesophageal reflux symptoms. To induce UES restriction, we used a handmade device that with adjustment could selectively apply 0, 20, 30, or 40 mmHg pressure perpendicularly to the cricoid cartilage. Deglutitive pharyngeal and UES pressure phenomena were determined during dry and 5- and 10-ml water swallows × 3 for each of the UES perturbations. External cricoid pressure against the UES resulted in a significant increase in hypopharyngeal intrabolus pressure and UES nadir deglutitive relaxation pressure for all tested swallowed volumes (P < 0.05). Application of external cricoid pressure increased the length of the UES high pressure zone from 2.5 ± 0.2 to 3.1 ± 0.2, 3.5 ± 0.1, and 3.7 ± 0.1 cm for 20, 30, and 40 mmHg cricoid pressure, respectively (P < 0.05). External cricoid pressure had no significant effect on pharyngeal peristalsis. On the other hand, irrespective of external cricoid pressure deglutitive velopharyngeal contractile integral progressively increased with increased swallowed volumes (P < 0.05). In conclusion, acute experimental restriction of UES opening by external cricoid pressure manifests the pressure characteristics of increased resistance to UES transsphincteric flow observed clinically without affecting the pharyngeal peristaltic contractile function.

Intermittent theta burst stimulation (iTBS) is a novel, non-invasive form of brain stimulation capable of facilitating excitability of the human primary motor cortex with therapeutic potential in the treatment of neurological conditions, such as multiple sclerosis. The objectives of this study were to evaluate the effects of iTBS on cortical properties in the human pharyngeal motor system. Transcranial magnetic stimulation (TMS)-evoked pharyngeal motor responses were recorded via a swallowed intra-luminal catheter and used to assess motor cortical pathways to the pharynx in both hemispheres before and for up to 90 min after iTBS in 15 healthy adults (nine male/six female, 22-59 years old). Active/sham iTBS comprised 600 intermittent repetitive TMS pulses, delivered in a double-blind pseudo-randomised order over each hemisphere on separate days at least 1 week apart. Abductor pollicis brevis (APB) recordings were used as control. Hemispheric interventional data were compared with sham using repeated-measures anova. iTBS was delivered at an average intensity of 43±1% of stimulator output. Compared with sham, iTBS to the hemisphere with stronger pharyngeal projections induced increased responses only in the contralateral weaker projection 60-90 min post-iTBS (maximum 54±19%, P≤0.007), with no change in stronger hemisphere responses. By contrast, iTBS to weaker projections had no significant effects (P=0.39) on either hemisphere. APB responses similarly did not change significantly (P=0.78) across all study arms. We conclude that iTBS can induce remote changes in corticobulbar excitability. While further studies will clarify the extent of these changes, iTBS holds promise as a potential treatment for dysphagia after unilateral brain damage. © 2012 The Authors.

Prader-Willi Syndrome (PWS) is caused by a genetic imprinting abnormality resulting from the lack of expression of the paternal genes at 15q11-q13. Intellectual disability, low muscle tone, and life-threatening hyperphagia are hallmarks of the phenotype. The need for the Heimlich maneuver, death from choking, and pulmonary infection occur in a disproportionally high number of persons with PWS. The widely held belief is that eating behaviors are responsible for choking and aspiration; yet, no investigation had sought to determine if swallowing impairments were present in persons with PWS. To address this research and clinical gap, simultaneous videofluoroscopy and nasal respiratory signals were used to record swallowing function and breathing/swallowing coordination in 30 participants with PWS. Subjects consumed thin liquid and barium cookies under two randomized conditions as follows: (i) controlled (cues to swallow and standardized bolus sizes); (ii) spontaneous (no cues or bolus size control). Under videofluoroscopy, the cohort showed disordered pharyngeal and esophageal swallowing in both conditions with disturbances in timing, clearance, and coordination of swallowing with the respiratory cycle. No participant showed a sensory response such as attempting to clear residue or coughing; thereby supporting the lack of overt symptoms. We conclude that the high death rate from choking and pulmonary infection in children and adults with PWS may be related, in part, to underlying, asymptomatic dysphagia. The combination of rapid eating and dysphagia would increase the risk of aspiration-related morbidity and mortality. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Dysphagia in the elderly.

PubMed

Khan, Abraham; Carmona, Richard; Traube, Morris

2014-02-01

Dysphagia, or difficulty swallowing, is a common problem in the elderly. Based on the initial clinical history and physical examination, the dysphagia is assessed as either primarily oropharyngeal or esophageal in origin. Most oropharyngeal dysphagia is of neurologic origin, and management is coordinated with a clinical swallow specialist in conjunction with an ear, nose, and throat (ENT) physician if warning signs imply malignancy. Several structural and functional esophageal disorders can cause dysphagia. If a patient has likely esophageal dysphagia, a video barium esophagram is a good initial test, and referral to a gastroenterologist is generally warranted leading to appropriate treatment.

The factors that determine how people eat when they are healthy or have disease have not been defined. We used high resolution manometry (HRM) to assess pharyngeal swallowing and oesophageal motility during ingestion of a solid test meal (STM) in healthy volunteers and patients with motility disorders. This study was based at University Hospital Zurich (Zürich, Switzerland). Healthy volunteers who responded to an advertisement completed HRM with ten single water swallows (SWS) in recumbent and upright positions followed by a 200 g rice STM in the upright position. Healthy volunteers were stratified for age and sex to ensure a representative population. For comparison, consecutive patients with major motility disorders on SWS and patients with dysphagia but no major motility disorders on SWS (disease controls) were selected from a database that was assembled prospectively; the rice meal data were analysed retrospectively. During STM, pharyngeal swallows were timed and oesophageal contractions were classified as representing normal motility or different types of abnormal motility in accordance with established metrics. Factors that could potentially be associated with eating speed were investigated, including age, sex, body-mass index, and presence of motility disorder. We compared diagnoses based on SWS findings, assessed with the Chicago Classification v3.0, with those based on STM findings, assessed with the Chicago Classification adapted for solids. These studies are registered with ClinicalTrials.gov, numbers NCT02407938 and NCT02397616. Between April 2, 2014, and May 13, 2015, 72 healthy volunteers were recruited and underwent HRM. Additionally, we analysed data from 54 consecutive patients with major motility disorders and 53 with dysphagia but no major motility disorders recruited between April 2, 2013, and Dec 18, 2014. We found important variations in oesophageal motility and eating speed during meal ingestion in healthy volunteers and patients. Increased

OBJECTIVE: To review the problem of dysphagia in the elderly so that primary care physicians are better able to recognize and manage it. QUALITY OF EVIDENCE: Dysphagia, a prevalent problem in the elderly, causes significant morbidity and even mortality. Age-related deterioration of the oropharyngeal phase of swallowing is well documented. Diagnosis and treatment of dysphagia in the elderly is based mainly on clinical experience with large groups of patients. Few controlled clinical trials have been conducted. MAIN FINDINGS: Oropharyngeal dysphagia in the elderly is often due to irreversible neuromuscular disease. These patients benefit from swallowing therapy performed by speech pathologists. Esophageal causes of dysphagia are similar in the elderly and young patients, and the approach to treatment is also similar, although noninvasive forms of therapy play a larger role for elderly patients. CONCLUSIONS: Dysphagia is a common problem that lowers quality of life for the elderly. Primary care physicians must be aware of causes of dysphagia for which specific treatments are available, as well as of the role of nonspecific treatments offered by ancillary health professionals.

This article discusses the extraesophageal manifestations of gastroesophageal reflux disease, focusing primarily on the gamut of pharyngeal abnormalities that can be detected on barium swallows. Abnormalities of pharyngeal swallowing caused by gastroesophageal reflux are illustrated. We particularly emphasize how pharyngoesophageal relationships can guide the radiologist for performing tailored barium swallows to optimally evaluate pharyngeal abnormalities in patients with underlying gastroesophageal reflux disease.

Corynebacterium diphtheriae employs specific minor pilins to target human pharyngeal epithelial cells

Mandlik, Anjali; Swierczynski, Arlene; Das, Asis; Ton-That, Hung

Summary Adherence to host tissues mediated by pili is pivotal in the establishment of infection by many bacterial pathogens. Corynebacterium diphtheriae assembles on its surface three distinct pilus structures. The function and the mechanism of how various pili mediate adherence, however, have remained poorly understood. Here we show that the SpaA-type pilus is sufficient for the specific adherence of corynebacteria to human pharyngeal epithelial cells. The deletion of the spaA gene, which encodes the major pilin forming the pilus shaft, abolishes pilus assembly but not adherence to pharyngeal cells. In contrast, adherence is greatly diminished when either minor pilin SpaB or SpaC is absent. Antibodies directed against either SpaB or SpaC block bacterial adherence. Consistent with a direct role of the minor pilins, latex beads coated with SpaB or SpaC protein bind specifically to pharyngeal cells. Therefore, tissue tropism of corynebacteria for pharyngeal cells is governed by specific minor pilins. Importantly, immunoelectron microscopy and immunofluorescence studies reveal clusters of minor pilins that are anchored to cell surface in the absence of a pilus shaft. Thus, the minor pilins may also be cell wall anchored in addition to their incorporation into pilus structures that could facilitate tight binding to host cells during bacterial infection.

Objective: To determine the occurrence of clinical signs of dysphagia in infants with acute viral bronchiolitis, to compare the respiratory parameters during deglutition, and to ensure the intra- and inter- examiners agreement, as well as to accomplish intra and interexaminators concordance of the clinical evaluation of the deglutition. Methods: This was a cross-sectional study of 42 infants aged 0-12 months. The clinical evaluation was accompanied by measurements of respiratory rate and pulse oximetry. A score of swallowing disorders was designed to establish associations with other studied variables and to ensure the intra- and interrater agreement of clinical feeding assessments. Caregivers also completed a questionnaire about feeding difficulties. Significance was set at p<0.05. Results: Changes in the oral phase (prolonged pauses) and pharyngeal phase (wheezing, coughing and gagging) of swallowing were found. A significant increase in respiratory rate between pre- and post-feeding times was found, and it was determined that almost half of the infants had tachypnea. An association was observed between the swallowing disorder scores and a decrease in oxygen saturation. Infants whose caregivers reported feeding difficulties during hospitalization stated a significantly greater number of changes in the swallowing evaluation. The intra-rater agreement was considered to be very good. Conclusions: Infants with acute viral bronchiolitis displayed swallowing disorders in addition to changes in respiratory rate and measures of oxygen saturation. It is suggested, therefore, that infants displaying these risk factors have a higher probability of dysphagia. PMID:25479843

Oropharyngeal dysphagia.

PubMed

Cook, Ian J

2009-09-01

Although the aging process per se can produce measurable changes in the normal oropharyngeal swallow, these changes alone are rarely sufficient to cause clinically apparent dysphagia. The causes of oropharyngeal dysphagia in the elderly are predominantly neuromyogenic, with the most common cause being stroke. The evaluation of oropharyngeal dysphagia in the elderly involves early exclusion of structural abnormalities, detection of aspiration by videofluoroscopy which might dictate early introduction of nonoral feeding, and exclusion of underlying systemic and neuromyogenic causes that have specific therapies in their own right. Such conditions include Parkinson disease, myositis, myasthenia, and thyrotoxicosis. Management is best delivered by a multidisciplinary team involving physician, speech pathologist, nutritionist and, at times, a surgeon.

Pharyngitis is a very prevalent illness in the ambulatory care setting. Its diagnosis is a challenge, especially in the differentiation between the viric and streptococcal causes. A formulary was made to register the clinical and laboratory data; a throat swab for culture was obtained from all the children who presented to the emergency department with sore throat and/or signs of pharyngitis/tonsillitis, for a period of three months (15th of April to 15th of July of 2006). The signs and symptoms, prescribed antibiotherapy and frequency of false diagnostics were evaluated and the clinical suspicion compared with the diagnosis by culture. 158 children were evaluated, with a median age of four years, with a male predominance (56%). The period that showed the greatest number of cases was the first fifteen days of May. Forty-three percent of the cultures were positive for Streptococcus pyogenes. The more frequent signs and symptoms in pharyngitis were pharyngeal erythema (98%), fever (86%) and sore throat (78%). A significative statistical difference was found for cough, scarlatiniform rash, tonsillar exudate, palatal petechiae and tonsillar swelling. Of the signs and symptoms studied, only three of them presented a positive predictive value superior to 50%: scarlatiniform rash (85%), palatal petechiae (63%) and cough (57%). The presence of tonsillar exudate had a positive predictive value for non-streptococcal pharyngitis of 70%. Fifty-three percent of the doctors considered streptococcal pharyngitis highly probable, and from this, 56% had a positive culture for Streptococcus. Those who considered a low probability, the culture was positive in 28%. There were 37% of false diagnosis. The distinction between streptococcal pharyngitis and non-streptococcal pharyngitis is not always correct when based on clinical characteristics. The use of diagnostic tests is important in order to avoid unnecessary antibiotherapy as well as to allow the correct use in the positive cases.

Nutritional Aspects of Dysphagia Management.

PubMed

Gallegos, C; Brito-de la Fuente, E; Clavé, P; Costa, A; Assegehegn, G

This chapter describes the nutritional aspects of dysphagia management by starting with the definition of these two conditions (dysphagia and malnutrition) that share three main clinical characteristics: (a) their prevalence is very high, (b) they can lead to severe complications, and (c) they are frequently underrecognized and neglected conditions. From an anatomical standpoint, dysphagia can result from oropharyngeal and/or esophageal causes; from a pathophysiological perspective, dysphagia can be caused by organic or structural diseases (either benign or malignant) or diseases causing impaired physiology (mainly motility and/or perception disorders). This chapter gathers up-to-date information on the screening and diagnosis of oropharyngeal dysphagia, the consequences of dysphagia (aspiration pneumonia, malnutrition, and dehydration), and on the nutritional management of dysphagic patients. Concerning this last topic, this chapter reviews the rheological aspects of swallowing and dysphagia (including shear and elongational flows) and its influence on the characteristics of the enteral nutrition for dysphagia management (solid/semisolid foods and thickened liquids; ready-to-use oral nutritional supplements and thickening powders), with special focus on the real characteristics of the bolus after mixing with human saliva. © 2017 Elsevier Inc.

[Transdisciplinary approach for sarcopenia. Sarcopenic Dysphagia].

PubMed

Wakabayashi, Hidetaka

2014-10-01

Sarcopenic dysphagia is difficulty swallowing due to sarcopenia of generalized skeletal muscles and swallowing muscles. Presbyphagia refers to age-related changes in the swallowing mechanism in the elderly associated with a frailty in swallowing. Presbyphagia is different from dysphagia. The most common cause of dysphagia is stroke. However, sarcopenic dysphagia may be common in the elderly with sarcopenia and dysphagia. Frail elderly with aspiration pneumonia can simultaneously experience activity-, disease-, and nutrition-related sarcopenia of generalized skeletal muscles and swallowing muscles, resulting in the development of sarcopenic dysphagia. Consensus diagnostic criteria for sarcopenic dysphagia were proposed at the 19th Annual Meeting of the Japanese Society of Dysphagia Rehabilitation. The concept of rehabilitation nutrition as a combination of both rehabilitation and nutrition care management is useful for treatment of sarcopenic dysphagia. Therapy for sarcopenic dysphagia includes dysphagia rehabilitation, nutrition improvement and sarcopenia treatment. The core components of dysphagia rehabilitation are oral health care, rehabilitative techniques, and food modification. Nutrition improvement is important, because malnutrition contributes to the etiology of secondary sarcopenia and sarcopenic dysphagia. Assessment of the multi-factorial causes of primary and secondary sarcopenia is important because rehabilitation nutrition for sarcopenia differs depending on its etiology. Treatment of age-related sarcopenia should include resistance training and dietary supplements of amino acids. Therapy for activity-related sarcopenia includes reduced bed rest time and early mobilization and physical activity. Treatment for disease-related sarcopenia requires therapies for advanced organ failure, inflammatory disease, or malignancy, while therapy for nutrition-related sarcopenia involves appropriate nutrition management to increase muscle mass.

Increasing bolus viscosity of thin liquids is a basic therapeutic strategy to protect patients with oropharyngeal dysphagia (OD) from aspiration. However, conventional starch thickeners increase post-deglutitive residue. To assess the therapeutic effect of a new xanthan gum-based thickener, Resource ThickenUp Clear (Nestlé Health Science, Vevey, Switzerland) on patients with oropharyngeal dysphagia. We studied the effect of Resource ThickenUp Clear using a clinical method and videofluoroscopy on 120 patients with oropharyngeal dysphagia (66 with stroke, 41 older and 13 with neurodegenerative diseases) and 14 healthy volunteers while swallowing thin-liquid, nectar-like and spoon-thick boluses. We assessed the prevalence of signs of impaired safety and efficacy of swallow and the physiology of the swallow response. Increasing bolus viscosity with Resource ThickenUp Clear: (i) improved safety of swallow demonstrated by a reduction in the prevalence of cough and voice changes in the clinical study and penetrations and aspirations during video fluoroscopy. Prevalence of aspirations was 12.7% with thin liquid, 7.7% with nectar-like (P < 0.01) and 3.4% with spoon-thick (P < 0.01) viscosities. Penetration-Aspiration Scale was reduced from 3.24 ± 0.18 at thin liquid to 2.20 ± 0.18 at nectar-like (P < 0.001) and to 1.53 ± 0.13 at spoon-thick (P < 0.001) viscosities; (ii) did not enhance pharyngeal residue; (iii) nectar-like viscosity did not affect bolus velocity nor timing of swallow response and (iv) spoon-thick viscosity reduced bolus velocity. Resource ThickenUp Clear improves the safety of swallow without increasing residue providing a viscosity-dependent therapeutic effect for patients with oropharyngeal dysphagia. At nectar viscosity, the effect is due to intrinsic texture properties, spoon-thick viscosity adding changes in swallow physiology. NCT01158313. © 2014 John Wiley & Sons Ltd.

Common Questions About Streptococcal Pharyngitis.

Group A beta-hemolytic streptococcal (GABHS) infection causes 15% to 30% of sore throats in children and 5% to 15% in adults, and is more common in the late winter and early spring. The strongest independent predictors of GABHS pharyngitis are patient age of five to 15 years, absence of cough, tender anterior cervical adenopathy, tonsillar exudates, and fever. To diagnose GABHS pharyngitis, a rapid antigen detection test should be ordered in patients with a modified Centor or FeverPAIN score of 2 or 3. First-line treatment for GABHS pharyngitis includes a 10-day course of penicillin or amoxicillin. Patients allergic to penicillin can be treated with firstgeneration cephalosporins, clindamycin, or macrolide antibiotics. Nonsteroidal anti-inflammatory drugs are more effective than acetaminophen and placebo for treatment of fever and pain associated with GABHS pharyngitis; medicated throat lozenges used every two hours are also effective. Corticosteroids provide only a small reduction in the duration of symptoms and should not be used routinely.

Fgfr1 regulates patterning of the pharyngeal region

PubMed Central

Trokovic, Nina; Trokovic, Ras; Mai, Petra; Partanen, Juha

2003-01-01

Development of the pharyngeal region depends on the interaction and integration of different cell populations, including surface ectoderm, foregut endoderm, paraxial mesoderm, and neural crest. Mice homozygous for a hypomorphic allele of Fgfr1 have craniofacial defects, some of which appeared to result from a failure in the early development of the second branchial arch. A stream of neural crest cells was found to originate from the rhombomere 4 region and migrate toward the second branchial arch in the mutants. Neural crest cells mostly failed to enter the second arch, however, but accumulated in a region proximal to it. Both rescue of the hypomorphic Fgfr1 allele and inactivation of a conditional Fgfr1 allele specifically in neural crest cells indicated that Fgfr1 regulates the entry of neural crest cells into the second branchial arch non-cell-autonomously. Gene expression in the pharyngeal ectoderm overlying the developing second branchial arch was affected in the hypomorphic Fgfr1 mutants at a stage prior to neural crest entry. Our results indicate that Fgfr1 patterns the pharyngeal region to create a permissive environment for neural crest cell migration. PMID:12514106

Descriptive study. San Fernando 2 Health Centre, Madrid (outer urban area), Spain. On hundred forty patients over 14 years old who had a "sore throat" as main symptom and attended clinic between 14 February and 12 May, 2005. Sensitivity, specificity, positive and negative predictive values, and the probability quotients of the Centor score were determined. Pharyngeal throat culture was used as the reference method. Thirty four patients had positive throat culture (24.3%; 95% CI, 17.6%-32.4%). Finding the 4 criteria in the Centor score had a positive predictive value (PPV) of 48.1% (95% CI, 30.7%-66.0%) and a negative predictive value (NPV) of 81.4% (95% CI, 73.3%-87.5%); although only fever (OR, 3.64; 95% CI, 1.40-9.49) and tonsillar exudate (OR, 6.18; 95% CI, 2.08-18.35) were linked to streptococcal aetiology. The high NPV and specificity of the clinical score makes the diagnosis of non-streptococcal pharyngitis very accurate. However, the PPV is low: a high Centor score (3 or 4 criteria) does not mean streptococcal pharyngitis with certainty. What approach to take with patients suspected of streptococcal pharyngitis is not yet resolved (microbiological test, early antibiotic, or postponed antibiotic).

Dysphagia lusoria: a late onset presentation.

Dysphagia lusoria is a term used to describe dysphagia secondary to vascular compression of the oesophagus. The various embryologic anomalies of the arterial brachial arch system often remain unrecognised and asymptomatic, but in 30%-40% of cases can result in tracheo-oesophageal symptoms, which in the majority of cases manifest as dysphagia. Diagnosis of dysphagia lusoria is via barium swallow and chest Computed tomography scan. Manometric abnormalities are variable, but age-related manometric changes may contribute to clinically relevant dysphagia lusoria in patients who present later in life. Our report describes a case of late-onset dysphagia secondary to a right aortic arch with an aberrant left subclavian artery, which represents a rare variant of dysphagia lusoria. The patient had proven additional oesophageal dysmotility with solid bolus only and a clinical response to dietary modification.

Dysphagia (swallowing problems) are common after stroke and can cause chest infection and malnutrition. Dysphagic, and malnourished, stroke patients have a poorer outcome. To assess the effectiveness of interventions for the treatment of dysphagia (swallowing therapy), and nutritional and fluid supplementation, in patients with acute and subacute (within six months from onset) stroke. We searched the Cochrane Stroke Group Trials Register (February 2012), MEDLINE (1966 to July 2011), EMBASE (1980 to July 2011), CINAHL (1982 to July 2011) and Conference Proceedings Citation Index- Science (CPCI-S) (1990 to July 2011). We also searched the reference lists of relevant trials and review articles, searched Current Controlled Trials and contacted researchers (July 2011). For the previous version of this review we contacted the Royal College of Speech and Language Therapists and equipment manufacturers. Randomised controlled trials (RCTs) in dysphagic stroke patients, and nutritional supplementation in all stroke patients, where the stroke occurred within six months of enrolment. Two review authors independently applied the inclusion criteria, assessed trial quality, and extracted data, and resolved any disagreements through discussion with a third review author. We used random-effects models to calculate odds ratios (OR), 95% confidence intervals (95% CI), and mean differences (MD). The primary outcome was functional outcome (death or dependency, or death or disability) at the end of the trial. We included 33 studies involving 6779 participants.Swallowing therapy: acupuncture, drug therapy, neuromuscular electrical stimulation, pharyngeal electrical stimulation, physical stimulation (thermal, tactile), transcranial direct current stimulation, and transcranial magnetic stimulation each had no significant effect on case fatality or combined death or dependency. Dysphagia at end-of-trial was reduced by acupuncture (number of studies (t) = 4, numbers of participants (n) = 256

Lateral medullary stroke is typically associated with increased likelihood of occurrence of dysphagia and exhibits the most severe and persistent form. Worldwide little research exists on dysphagia in brainstem stroke. An estimated 15% of all patients admitted to stroke rehabilitation units experience a brainstem stroke out of which about 47% suffer from dysphagia. In India, a study showed that 22.3% of posterior circulation stroke patients develop dysphagia. Dearth of literature on dysphagia and its outcome in brainstem stroke particularly lateral medullary stroke motivated the author to present an actual case study of a patient who had dysphagia following a lateral medullary infarct. This paper documents the severity and management approach of dysphagia in brainstem stroke, with traditional dysphagia therapy and VitalStim therapy.

Oesophageal dysphagia: manifestations and diagnosis.

PubMed

Zerbib, Frank; Omari, Taher

2015-06-01

Oesophageal dysphagia is a common symptom, which might be related to severe oesophageal diseases such as carcinomas. Therefore, an organic process must be ruled out in the first instance by endoscopy in all patients presenting with dysphagia symptoms. The most prevalent obstructive aetiologies are oesophageal cancer, peptic strictures and eosinophilic oesophagitis. Eosinophilic oesophagitis is one of the most common causes of dysphagia in adults and children, thus justifying the need to obtain oesophageal biopsy samples from all patients presenting with unexplained dysphagia. With the advent of standardized high-resolution manometry and specific metrics to characterize oesophageal motility, the Chicago classification has become a gold-standard algorithm for manometric diagnosis of oesophageal motor disorders. In addition, sophisticated investigations and analysis methods that combine pressure and impedance measurement are currently in development. In the future, these techniques might be able to detect subtle pressure abnormalities during bolus transport, which could further explain pathophysiology and symptoms. The degree to which novel approaches will help distinguish dysphagia caused by motor abnormalities from functional dysphagia still needs to be determined.

[Aural Stimulation with Capsaicin Ointment Improved the Swallowing Function in Patients with Dysphagia: Evaluation by the SMRC Scale].

Cough and swallowing reflexes are important airway-protective mechanisms against aspiration. Angiotensin-converting enzyme (ACE) inhibitors, one of the side effects of which is cough, have been reported to reduce the incidence of aspiration pneumonia in hypertensive patients with stroke. ACE inhibitors have also been reported to improve the swallowing function in post-stroke patients. On the other hand, stimulation of the Arnold nerve, the auricular branch of the vagus, triggers the cough reflex (Arnold's ear-cough reflex). Capsaicin, an agonist of Transient Receptor Potential Vanilloid 1 (TRPV1), has been shown to activate the peripheral sensory C-fibers. Stimulation of the sensory branches of the vagus in the laryngotracheal mucosa with capsaicin induces the cough reflex and has been reported to improve the swallowing function in patients with dysphagia. In our previous study, we showed that aural stimulation of the Arnold nerve with 0.025% capsaicin ointment improved the swallowing function, as evaluated by the endoscopic swallowing score, in 26 patients with dysphagia. In the present study, the video images of swallowing recorded in the previous study were re-evaluated using the SMRC scale by an independent otolaryngologist who was blinded to the information about the patients and the endoscopic swallowing score. The SMRC scale is used to evaluate four aspects of the swallowing function: 1) Sensory: the initiation of the swallowing reflex as assessed by the white-out timing; 2) Motion: the ability to hold blue-dyed water in the oral cavity and induce laryngeal elevation; 3) Reflex: glottal closure and the cough reflex induced by touching the epiglottis or arytenoid with the endoscope; 4) Clearance: pharyngeal clearance of the blue-dyed water after swallowing. Accordingly, we demonstrated that a single application of capsaicin ointment to the external auditory canal of patients with dysphagia significantly improved the R, but not the S, M or C scores, and this

Velo-pharyngeal dysfunction: Evaluation and management

PubMed Central

Marsh, Jeffrey L.

2009-01-01

Separation of the nasal and oral cavities by dynamic closure of the velo-pharyngeal port is necessary for normal speech and swallowing. Velo-pharyngeal dysfunction (VPD) may either follow repair of a cleft palate or be independent of clefting. While the diagnosis of VPD is made by audiologic perceptual evaluation of speech, identification of the mechanism of the dysfunction requires instrumental visualization of the velo-pharyngeal port during specific speech tasks. Matching the specific intervention for management of VPD with the type of dysfunction, i.e. differential management for differential diagnosis, maximizes the result while minimizing the morbidity of the intervention.

Neurogenic dysphagia (ND) is a prevalent condition that accounts for significant mortality and morbidity worldwide. Screening and follow-up are critical for early diagnosis and management which can mitigate its complications and be cost-saving. The aims of this study are to provide a comprehensive investigation of the dysphagia limit (DL) in a large diverse cohort and to provide a longitudinal assessment of dysphagia in a subset of subjects. We developed a quantitative and noninvasive method for objective assessment of dysphagia by using laryngeal sensor and submental electromyography. DL is the volume at which second or more swallows become necessary to swallow the whole amount of bolus. This study represents 17 years experience with the DL approach in assessing ND in a cohort of 1278 adult subjects consisting of 292 healthy controls, 784 patients with dysphagia, and 202 patients without dysphagia. A total of 192 of all patients were also reevaluated longitudinally over a period of 1-19 months. DL has 92% sensitivity, 91% specificity, 94% positive predictive value, and 88% negative predictive value with an accuracy of 0.92. Patients with ALS, stroke, and movement disorders have the highest sensitivity (85-97%) and positive predictive value (90-99%). The clinical severity of dysphagia has significant negative correlation with DL (r=-0.67, p<0.0001). We propose the DL as a reliable, quick, noninvasive, quantitative test to detect and follow both clinical and subclinical dysphagia and it can be performed in an EMG laboratory. Our study provides specific quantitative features of DL test that can be readily utilized by the neurologic community and nominates DL as an objective and robust method to evaluate dysphagia in a wide range of neurologic conditions.

Dysphagia is a life-threatening disorder caused by many medical conditions such as stroke, neurological disorders, tumors, etc. The symptoms of dysphagia are quite variable and diagnosed by observation or through screening involving instrumental swallowing examinations such as video-fluoroscopy and video-endoscopy, to determine functional severity and treatment-prognosis. Direct- and indirect-therapy is used with and without food, respectively. Swallowing rehabilitation is very effective, and could be used in conjunction with compensatory techniques.

To assess the frequency of anterior pharyngeal pouch formation after total laryngectomy, and to discuss the causes and consequences of anterior pharyngeal pouch formation. A prospective, observational study of 43 patients undergoing total laryngectomy. Data collected included laryngeal defect closure type, tumour staging and demographic information. A barium swallow was performed on day 7-14 after surgery to assess for anterior pharyngeal pouch formation and fistula formation. The incidence of anterior pharyngeal pouch formation was 47 per cent. Patients who did not have an anterior pharyngeal pouch on swallow imaging assessment were less likely to develop a pharyngo-cutaneous fistula. There was no statistically significant association between laryngeal defect closure type and anterior pharyngeal pouch formation. The anterior pharyngeal pouch is a dynamic phenomenon best investigated with a fluoroscopic swallow imaging study. Its causes are multi-factorial. Absence of an anterior pharyngeal pouch appears to confer protection against pharyngo-cutaneous fistula formation, hastening commencement of adjuvant therapy and an oral diet.

Dysphagia is a common complaint in patients presenting for radiological or endoscopic examination of the esophagus and is usually due to functional or structural abnormalities of the esophageal body or esophagogastric region. The authors review the radiological evaluation of the esophagus and esophagogastric region in patients with esophageal dysphagia and discuss the roentgenographic techniques used, radiological efficacy for common structural disorders, and evaluation of esophageal motor function. Comparison is made with endoscopy in assessing dysphagia, with the conclusion that the radiological examination be used initially in patients with this complaint.

Elderly patients are inherently predisposed to dysphagia predominately because of comorbid health conditions. With the aging of the population in the United States, along with the increased prevalence of obesity and gastroesophageal reflux disease, healthcare providers will increasingly encounter older patients with either oropharyngeal or esophageal disease and complaints of dysphagia. Useful tests to evaluate dysphagia include the videofluoroscopic swallowing study and the fiberoptic endoscopic evaluation of swallowing. Swallow rehabilitation is useful to help patients compensate for swallowing difficulty and ultimately help strengthen the neuromusculature involved in swallowing. PMID:24772045

Difficulty swallowing or dysphagia can be present in children and adults alike. Pediatric dysphagias have long been recognized in the literature. Certain groups of infants with specific developmental and/or medical conditions have been identified as being at high risk for developing dysphagia. Still others may present with a swallowing or feeding problem as their primary symptom. Left untreated, these problems in infants and children can lead to failure to thrive, aspiration pneumonias, gastroesophageal reflux, and/or the inability to establish and maintain proper nutrition and hydration. Awareness of the prevalence of pediatric dysphagia in today's population and the signs and symptoms of this condition aids in its treatment. Early detection of dysphagia in infants and children is important to prevent or minimize complications. This article provides a review of symptoms, etiologies, and resources available regarding management of this condition to help the primary care physician and the families of young children and infants in its management.

A randomized controlled study of neuromuscular electrical stimulation in oropharyngeal dysphagia secondary to acquired brain injury.

To evaluate the effectiveness of neuromuscular electrical stimulation (NMES) treatment in patients with oropharyngeal dysphagia secondary to acquired brain injury. Twenty patients with neurological oropharyngeal dysphagia (14 stroke and six severe traumatic brain injury) were enrolled in a prospective randomized study, with patients and assessors blinded (to group allocation): 10 patients underwent NMES and conventional swallowing therapy and 10 patients underwent sham electrical stimulation (SES) and conventional swallowing therapy. Both groups completed 20 sessions. At baseline, at the end of treatment (1 month) and at 3-month follow-up, clinical, videofluoroscopic and esophageal manometric analyses were done. Feeding swallowing capacity was evaluated using the functional oral intake scale (FOIS). Mean FOIS score before treatment was 1.9 for the NMES group and 2.1 for the SES group. After treatment, the NMES group increased by 2.6 points (4.5 points) compared with only 1 point (3.1 points) for the SES group (P = 0.005). At 3 months of follow-up, mean scores were 5.3 and 4.6 respectively; thus, both groups improved similarly. At that time point (3 months), tracheal aspiration persisted in six patients in each group. However, a significant improvement in relation to the bolus viscosity at which aspiration appeared was found in the NMES group versus the SES group (P = 0.015). Also, a significant increase (P = 0.04) in pharyngeal amplitude contraction was observed at the end of treatment (1 month) in the NMES group compared with the SES group. Neuromuscular electrical stimulation significantly accelerated swallowing function improvement in patients with oropharyngeal dysphagia secondary to acquired brain injury. © 2015 EAN.

The aims of this study were to evaluate the prevalence and the clinical predictors of dysphagia and to determine the characteristics of videofluoroscopic swallowing study findings in infants after open heart procedures. This study is a retrospective review of 146 infants who underwent open heart surgery. The infants with dysphagia were compared with those without dysphagia. The videofluoroscopic swallowing study findings of the infants with dysphagia were also evaluated. Of the 146 infants who underwent open heart surgery, 35 (24.0%) had dysphagia symptoms. The infants with dysphagia had lower body weight at operation, more malformation syndromes, longer operation times, and more complex operations than did the infants without dysphagia. In addition, the infants with dysphagia required more time to achieve full oral feeding and had longer hospital stays. Thirty-three infants underwent videofluoroscopic swallowing study: 32 (97.0%) exhibited at least one abnormal finding among the videofluoroscopic swallowing study parameters and 21 (63.6%) exhibited tracheal aspiration. Given the high rate of aspiration in the infants who underwent open heart procedures, monitoring and prompt recognition of the signs and the risk factors of dysphagia may substantially improve infant care with oral feeding and reduce the duration of hospital stays.

Neuromuscular electrical stimulation (NMES) has been used as a therapeutic intervention for dysphagia. However, the therapeutic effects of NMES lack supporting evidence. In recent years, NMES combined with traditional swallowing therapy has been used to improve functional recovery in patients with post-stroke dysphagia. This study aimed to investigate the effects of effortful swallowing combined with neuromuscular electrical stimulation on hyoid bone movement and swallowing function in stroke patients. Fifty stroke patients with mild dysphagia who were able to swallow against the resistance applied by using NMES and cooperate actively in training were included. This study was designed as a 6-week single-blind, randomised, controlled study. In the experimental group, two pairs of electrodes were placed horizontally in the infrahyoid region to depress the hyoid bone. The NMES intensity was increased gradually until the participants felt a grabbing sensation in their neck and performed an effortful swallow during the stimulation. In the placebo group, the same procedure was followed except for the intensity, which was increased gradually until the participants felt an electrical sensation. All participants underwent this intervention for 30 min per session, 5 sessions per week, for 6 weeks. Videofluoroscopic swallowing studies (VFSS) were carried out before and after the intervention and kinematics of the hyoid bone and swallowing function were analysed based on the VFSS. The experimental group revealed a significant increase in anterior and superior hyoid bone movement and the pharyngeal phase of the swallowing function. This intervention can be used as a novel remedial approach in dysphagic stroke patients. © 2016 John Wiley & Sons Ltd.

Infancy and childhood represent a time of unparalleled physical growth and cognitive development. In order for infants and children to reach their linear and neurological growth potential, they must be able to reliably and safely consume sufficient energy and nutrients. Swallowing difficulties (dysphagia) in pediatric populations can have a detrimental effect on dietary intake and, thus, growth and development. As a result, it is imperative to accurately identify and appropriately manage dysphagia in pediatric populations. This article provides an overview of dysphagia in children, as well as common causes of childhood swallowing difficulties, populations at risk for pediatric dysphagia, techniques used to assess swallowing in pediatric patients, and the current treatment options available for infants and children with dysphagia. © 2015 S.

The pharyngeal skeleton is a key vertebrate anatomical system in debates on the origin of jaws and gnathostome (jawed vertebrate) feeding. Furthermore, it offers considerable potential as a source of phylogenetic data. Well-preserved examples of pharyngeal skeletons from stem-group gnathostomes remain poorly known. Here, we describe an articulated, nearly complete pharyngeal skeleton in an Early Devonian placoderm fish, Paraplesiobatis heinrichsi Broili, from Hunsrück Slate of Germany. Using synchrotron light tomography, we resolve and reconstruct the three-dimensional gill arch architecture of Paraplesiobatis and compare it with other gnathostomes. The preserved pharyngeal skeleton comprises elements of the hyoid arch (probable ceratohyal) and a series of branchial arches. Limited resolution in the tomography scan causes some uncertainty in interpreting the exact number of arches preserved. However, at least four branchial arches are present. The final and penultimate arches are connected as in osteichthyans. A single median basihyal is present as in chondrichthyans. No dorsal (epibranchial or pharyngobranchial) elements are observed. The structure of the pharyngeal skeleton of Paraplesiobatis agrees well with Pseudopetalichthys from the same deposit, allowing an alternative interpretation of the latter taxon. The phylogenetic significance of Paraplesiobatis is considered. A median basihyal is likely an ancestral gnathostome character, probably with some connection to both the hyoid and the first branchial arch pair. Unpaired basibranchial bones may be independently derived in chondrichthyans and osteichthyans. © 2017 The Authors Journal of Morphology Published by Wiley Periodicals, Inc.

Dysphagia is commonly attributed to disorders arising from dysfunction of the oesophageal mucosa or oesophageal motility. Mediastinal structures causing compression of the oesophagus remain a rare presenting cause of dysphagia. We report a case of a woman presenting with dysphagia to solid foods and associated symptoms of weight loss. Traditional evaluation for dysphagia was unrevealing until cross-sectional imaging suggested a mediastinal obstructive process. The finding of a mediastinal granuloma, distinct from mediastinal fibrosis, as the aetiology of dysphagia is a rare finding, with specific treatment implications. The patient was treated with itraconazole antifungal therapy with an improvement in her symptoms. 2016 BMJ Publishing Group Ltd.

The aim of this study was to compare current application, practice patterns, clinical outcomes, and professional attitudes of dysphagia practitioners regarding electrical stimulation (e-stim) therapy with similar data obtained in 2005. A web-based survey was posted on the American Speech-Language-Hearing Association Special Interest Group 13 webpage for 1 month. A total of 271 survey responses were analyzed and descriptively compared with the archived responses from the 2005 survey. Results suggested that e-stim application increased by 47% among dysphagia practitioners over the last 10 years. The frequency of weekly e-stim therapy sessions decreased while the reported total number of treatment sessions increased between the two surveys. Advancement in oral diet was the most commonly reported improvement in both surveys. Overall, reported satisfaction levels of clinicians and patients regarding e-stim therapy decreased. Still, the majority of e-stim practitioners continue to recommend this treatment modality to other dysphagia practitioners. Results from the novel items in the current survey suggested that motor level e-stim (e.g. higher amplitude) is most commonly used during dysphagia therapy with no preferred electrode placement. Furthermore, the majority of clinicians reported high levels of self-confidence regarding their ability to perform e-stim. The results of this survey highlight ongoing changes in application, practice patterns, clinical outcomes, and professional attitudes associated with e-stim therapy among dysphagia practitioners.

Dysphagia is a prevalent difficulty among aging adults. Though increasing age facilitates subtle physiologic changes in swallow function, age-related diseases are significant factors in the presence and severity of dysphagia. Among elderly diseases and health complications, stroke and dementia reflect high rates of dysphagia. In both conditions, dysphagia is associated with nutritional deficits and increased risk of pneumonia. Recent efforts have suggested that elderly community dwellers are also at risk for dysphagia and associated deficits in nutritional status and increased pneumonia risk. Swallowing rehabilitation is an effective approach to increase safe oral intake in these populations and recent research has demonstrated extended benefits related to improved nutritional status and reduced pneumonia rates. In this manuscript, we review data describing age related changes in swallowing and discuss the relationship of dysphagia in patients following stroke, those with dementia, and in community dwelling elderly. Subsequently, we review basic approaches to dysphagia intervention including both compensatory and rehabilitative approaches. We conclude with a discussion on the positive impact of swallowing rehabilitation on malnutrition and pneumonia in elderly who either present with dysphagia or are at risk for dysphagia.

Objective To investigate the effect of laryngopharyngeal neuromuscular electrical stimulation (NMES) on dysphonia in patients with dysphagia caused by stroke or traumatic brain injury (TBI). Methods Eighteen patients participated in this study. The subjects were divided into NMES (n=12) and conventional swallowing training only (CST, n=6) groups. The NMES group received NMES combined with CST for 2 weeks, followed by CST without NMES for the next 2 weeks. The CST group received only CST for 4 weeks. All of the patients were evaluated before and at 2 and 4 weeks into the study. The outcome measurements included perceptual, acoustic and aerodynamic analyses. The correlation between dysphonia and swallowing function was also investigated. Results There were significant differences in the GRBAS (grade, roughness, breathiness, asthenia and strain scale) total score and sound pressure level (SPL) between the two groups over time. The NMES relative to the CST group showed significant improvements in total GRBAS score and SPL at 2 weeks, though no inter-group differences were evident at 4 weeks. The improvement of the total GRBAS scores at 2 weeks was positively correlated with the improved pharyngeal phase scores on the functional dysphagia scale at 2 weeks. Conclusion The results demonstrate that laryngopharyngeal NMES in post-stroke or TBI patients with dysphonia can have promising effects on phonation. Therefore, laryngopharyngeal NMES may be considered as an additional treatment option for dysphonia accompanied by dysphagia after stroke or TBI. PMID:27606266

Age-related loss of muscle bulk and strength (sarcopenia) is often cited as a potential mechanism underlying age-related changes in swallowing. Our goal was to explore this phenomenon in the pharynx, specifically, by measuring pharyngeal wall thickness and pharyngeal lumen area in a sample of young versus older women. MRI scans of the neck were retrospectively reviewed from 60 women equally stratified into three age groups (20s, 60s, 70+). Four de-identified slices were extracted per scan for randomized, blinded analysis: one mid-sagittal and three axial slices were selected at the anterior inferior border of C2 and C3, and at the pit of the vallecula. Pixel-based measures of pharyngeal wall thickness and pharyngeal lumen area were completed using ImageJ and then converted to metric units. Measures of pharyngeal wall thickness and pharyngeal lumen area were compared between age groups with one-way ANOVAs using Sidak adjustments for post-hoc pairwise comparisons. A significant main effect for age was observed across all variables whereby pharyngeal wall thickness decreased and pharyngeal lumen area increased with advancing age. Pairwise comparisons revealed significant differences between 20s versus 70+ for all variables and 20s versus 60s for all variables except those measured at C2. Effect sizes ranged from 0.54 to 1.34. Consistent with existing sacropenia literature, the pharyngeal muscles appear to atrophy with age and consequently, the size of the pharyngeal lumen increases.

Sore throat is a common complaint in children and adolescents. With increasing antimicrobial resistance because of antimicrobial overuse, accurate diagnosis is imperative. Appropriate management of acute pharyngitis depends on proper use and interpretation of clinical findings, rapid antigen-detection tests, and throat cultures. We surveyed pediatricians and family physicians to evaluate their management strategies for children and adolescents with acute pharyngitis and to assess the availability and use of diagnostic tests in office practice. In 2004, surveys were mailed to a random sample of 1000 pediatrician members of the American Academy of Pediatrics and 1000 family physician members of the American Academy of Family Physicians. We assessed factors associated with physicians using an appropriate management strategy for treating acute pharyngitis. Of 948 eligible responses, 42% of physicians would start antimicrobials before knowing diagnostic test results and continue them despite negative results, with 27% doing this often or always. When presented with clinical scenarios of patients with acute pharyngitis, < or =23% chose an empirical approach, 32% used an inappropriate strategy for a child with pharyngitis suggestive of group A Streptococcus, and 81% used an inappropriate strategy for a child with findings consistent with viral pharyngitis. Plating cultures in the office was associated with an appropriate management strategy, although not statistically significant. Solo/2-person practice and rural location were both independent factors predicting inappropriate strategies. There is much room for improvement in the management of acute pharyngitis in children and adolescents. Most physicians use appropriate management strategies; however, a substantial number uses inappropriate ones, particularly for children with likely viral pharyngitis. Efforts to help physicians improve practices will need to be multifaceted and should include health policy and

Molariform teeth comprised over 85% of total surface area of dentition in fish 265 mm long.

Dysphagia in Stroke: A New Solution

Langdon, Claire; Blacker, David

2010-01-01

Dysphagia is extremely common following stroke, affecting 13%–94% of acute stroke sufferers. It is associated with respiratory complications, increased risk of aspiration pneumonia, nutritional compromise and dehydration, and detracts from quality of life. While many stroke survivors experience a rapid return to normal swallowing function, this does not always happen. Current dysphagia treatment in Australia focuses upon prevention of aspiration via diet and fluid modifications, compensatory manoeuvres and positional changes, and exercises to rehabilitate paretic muscles. This article discusses a newer adjunctive treatment modality, neuromuscular electrical stimulation (NMES), and reviews the available literature on its efficacy as a therapy for dysphagia with particular emphasis on its use as a treatment for dysphagia in stroke. There is a good theoretical basis to support the use of NMES as an adjunctive therapy in dysphagia and there would appear to be a great need for further well-designed studies to accurately determine the safety and efficacy of this technique.

Randomized clinical trials (RCTs) are often known as the gold standard in treatment efficacy studies. This article defines the characteristics of RCTs and the factors that investigators must consider in designing clinical trials in dysphagia. Design issues unique to behavioral treatments often used in dysphagia are discussed. Ongoing RCTs in dysphagia are described including studies of (1) the effectiveness of the Shaker exercise versus standardized treatment in patients with severe dysphagia resulting from stroke or treatment for head and neck cancer who have been nonoral for at least three months; (2) the comparative effects of nectar- and honey-thickened liquids versus chin tuck posture and in patients with dementia or Parkinson's disease with or without dementia who aspirate on thin liquids; and (3) the comparative effects of muscle exercise versus sensory postural therapy for dysphagia resulting from treatment for head and neck cancer. Issues in generalizing from the results of clinical trials are also described.

Dysphagia can cause aspiration pneumonia. The condition of dysphagia is difficult to evaluate from outside. Therefore, a careful examination is necessary to grasp the state of swallowing of a patient accurately. However, it has been a difficult situation for a patient who cannot come to hospital for some reason to be examined by video fluoroscopy or video endoscopy. In recent years, a usefulness of video endoscopy in visiting home examination for dysphagia has been reported several times. And this video endoscopy examination is a valuable tool to detect a discrepancy between swallowing function and nutritional intake of the patient. Cooperative rehabilitation with such a careful examination is an important issue to be successful in dysphagia rehabilitation.

To analyze the nosazontology of pharyngeal paraesthesia and investigate the treatment. Two hundred and twelve misdiagnosed pharyngeal paraesthesia patients were investigated by history inquiry, routine examination, 24-hour esophageal pH monitoring, barium X-ray of the oesophagus, anxieties-athymic private measuring scale, coefficient of variation of the R-R (CVR-R), bioavailable testosterone detection (Bio-T), erection experiment and questionnaire about man climacteric syndrome. The concomitant symptoms and positions of pharyngeal paresthesia were also studied. We adopted individuallized sequential multi-therapy for every patient according to the cause of disease. The cause of disease within 212 cases of pharyngeal paraesthesia included 62 psychic trauma, 32 endocrine system disease, 106 upper gastrointestinal disease, circulatory disease, 9 circulatory disease, 3 idiopathic. With individualized treatment, 110 cases had fully recovered, 63 cases excellence and 31 cases utility, and the efficiency rate was 96.23%. Pharyngeal paraesthesia can be caused by several factors. Thorough examination and comprehensive analysis should be applied to those incurable patient who has been treated for a long time. Short course of treatment and irrational drug use are the main causes of short-term recurrence and unsatisfactory curative effect.

Dysphagia is associated with poor outcome in stroke patients. Studies investigating the association of dysphagia and early dysphagia screening (EDS) with outcomes in patients with acute ischemic stroke (AIS) are rare. The aims of our study are to investigate the association of dysphagia and EDS within 24 h with stroke-related pneumonia and outcomes. Over a 4.5-year period (starting November 2007), all consecutive AIS patients from 15 hospitals in Schleswig-Holstein, Germany, were prospectively evaluated. The primary outcomes were stroke-related pneumonia during hospitalization, mortality, and disability measured on the modified Rankin Scale ≥2-5, in which 2 indicates an independence/slight disability to 5 severe disability. Of 12,276 patients (mean age 73 ± 13; 49% women), 9,164 patients (74%) underwent dysphagia screening; of these patients, 55, 39, 4.7, and 1.5% of patients had been screened for dysphagia within 3, 3 to <24, 24 to ≤72, and >72 h following admission. Patients who underwent dysphagia screening were likely to be older, more affected on the National Institutes of Health Stroke Scale score, and to have higher rates of neurological symptoms and risk factors than patients who were not screened. A total of 3,083 patients (25.1%; 95% CI 24.4-25.8) had dysphagia. The frequency of dysphagia was higher in patients who had undergone dysphagia screening than in those who had not (30 vs. 11.1%; p < 0.001). During hospitalization (mean 9 days), 1,271 patients (10.2%; 95% CI 9.7-10.8) suffered from stroke-related pneumonia. Patients with dysphagia had a higher rate of pneumonia than those without dysphagia (29.7 vs. 3.7%; p < 0.001). Logistic regression revealed that dysphagia was associated with increased risk of stroke-related pneumonia (OR 3.4; 95% CI 2.8-4.2; p < 0.001), case fatality during hospitalization (OR 2.8; 95% CI 2.1-3.7; p < 0.001) and disability at discharge (OR 2.0; 95% CI 1.6-2.3; p < 0.001).

Deconditioning and frailty may contribute to dysphagia and aspiration. Early identification of patients at risk of aspiration is important. Aspiration prevention would lead to reduced morbidity and health care costs. We therefore wondered whether objective measurements of frailty could help identify patients at risk for dysphagia and aspiration. Consecutive patients (n = 183) were enrolled. Patient characteristics and objective measures of frailty were recorded prospectively. Variables tested included age, body mass index, grip strength, and 5 meter walk pace. Statistical analysis tested for association between these parameters and dysphagia or aspiration, diagnosed by instrumental swallowing examination. Of variables tested for association with grip strength, only age category (P = .003) and ambulatory status (P < .001) were significantly associated with grip strength in linear regression models. Whereas walk speed was not associated with dysphagia or aspiration, ambulatory status was significantly associated with dysphagia and aspiration in multivariable model building. Nonambulatory status is a predictor of aspiration and should be included in risk assessments for dysphagia. The relationship between frailty and dysphagia deserves further investigation. Frailty assessments may help identify those at risk for complications of dysphagia. © The Author(s) 2014.

Culture is insensitive for the detection of pharyngeal gonorrhoea but isolation is pivotal to antimicrobial resistance surveillance. The aim of this study was to ascertain whether recommendations provided to clinicians (doctors and nurses) on pharyngeal swabbing technique could improve gonorrhoea detection rates and to determine which aspects of swabbing technique are important for optimal isolation. This study was undertaken at the Melbourne Sexual Health Centre, Australia. Detection rates among clinicians for pharyngeal gonorrhoea were compared before (June 2006-May 2009) and after (June 2009-June 2012) recommendations on swabbing technique were provided. Associations between detection rates and reported swabbing technique obtained via a clinician questionnaire were examined. The overall yield from testing before and after provision of the recommendations among 28 clinicians was 1.6% (134/8586) and 1.8% (264/15,046) respectively (p=0.17). Significantly higher detection rates were seen following the recommendations among clinicians who reported a change in their swabbing technique in response to the recommendations (2.1% vs. 1.5%; p=0.004), swabbing a larger surface area (2.0% vs. 1.5%; p=0.02), applying more swab pressure (2.5% vs. 1.5%; p<0.001) and a change in the anatomical sites they swabbed (2.2% vs. 1.5%; p=0.002). The predominant change in sites swabbed was an increase in swabbing of the oropharynx: from a median of 0% to 80% of the time. More thorough swabbing improves the isolation of pharyngeal gonorrhoea using culture. Clinicians should receive training to ensure swabbing is performed with sufficient pressure and that it covers an adequate area that includes the oropharynx.

To compare results of a clinical scoring system for diagnosis of group A streptococcal pharyngitis with microbiologic results, when several different pharyngeal pathogens were tested simultaneously. Evaluation of clinical manifestations of 106 adult patients with pharyngitis of different microbial origin. General private practice; Health Center Pulssi, Turku, Finland. Adult patients whose chief complaints were sore throats. A symptom score that was assigned to each patient according to the total number of certain signs and symptoms that are postulated to increase the probability of group A streptococcal pharyngitis and blood measurements for infection. The highest symptom scores, 3 and 4, were found in 21 patients. These patients had pharyngitis due to group A streptococcus (four patients), group C streptococcus (four patients), group G streptococcus (two patients), group F streptococcus, Mycoplasma pneumoniae, Chlamydia pneumoniae, influenza A virus, influenza B virus, herpes simplex type 1 virus (two patients), and coxsackie B4 virus. No pathogen could be identified from three of the 21 patients. The C-reactive protein values and the leukocyte counts were raised significantly more often in streptococcal infections than in infections of other origin; the P values were .00016 and .028, respectively. Use of a clinical scoring system alone for diagnosis of pharyngitis may lead to improper use of anti-microbial agents. There is a need for accurate microbiologic diagnostic procedures in general practice to determine proper treatment of pharyngitis as well as to test the effect of antibacterial and, in the future, antiviral treatment in respiratory tract infections.

Presbyphagia and Sarcopenic Dysphagia: Association between Aging, Sarcopenia, and Deglutition Disorders.

PubMed

Wakabayashi, H

2014-01-01

Presbyphagia refers to age-related changes in the swallowing mechanism in the elderly associated with a frailty in swallowing. Presbyphagia is different from dysphagia. Sarcopenic dysphagia is difficulty swallowing due to sarcopenia of generalized skeletal muscles and swallowing muscles. Age-related loss of swallowing muscle mass becomes evident in the geniohyoid muscle and tongue. Elderly subjects with both sarcopenia and dysphagia may have not only disease-related dysphagia but also sarcopenic dysphagia. In cases of aspiration pneumonia, deterioration in activity-, disease-, and nutrition-related sarcopenia of generalized skeletal muscles and swallowing muscles may develop into sarcopenic dysphagia. Assessment of sarcopenic dysphagia includes evaluation of both dysphagia and sarcopenia. The 10-item Eating Assessment Tool (EAT-10) and a water test combined with pulse oximetry are useful for dysphagia screening. Assessment of the multi-factorial causes of sarcopenia including nutritional review is important, because rehabilitation of sarcopenic dysphagia differs depending on its etiology. Consensus diagnostic criteria for sarcopenic dysphagia were proposed at the 19th Annual Meeting of the Japanese Society of Dysphagia Rehabilitation. Rehabilitation for sarcopenic dysphagia includes treatment of both dysphagia and sarcopenia. The core components of dysphagia rehabilitation are oral health care, rehabilitative techniques, and food modification. The causes of adult malnutrition may also contribute to the etiology of secondary sarcopenia and sarcopenic dysphagia. Therefore, nutrition management is indispensable for sarcopenic dysphagia rehabilitation. In cases of sarcopenia with numerous complicating causes, treatment should include pharmaceutical therapies for age-related sarcopenia and comorbid chronic diseases, resistance training, early ambulation, nutrition management, protein and amino acid supplementation, and non-smoking.

Oropharyngeal dysphagia encompasses problems with the oral preparatory phase of swallowing (chewing and preparing the food), oral phase (moving the food or fluid posteriorly through the oral cavity with the tongue into the back of the throat) and pharyngeal phase (swallowing the food or fluid and moving it through the pharynx to the oesophagus). Populations of children with neurological impairment who commonly experience dysphagia include, but are not limited to, those with acquired brain impairment (for example, cerebral palsy, traumatic brain injury, stroke), genetic syndromes (for example, Down syndrome, Rett syndrome) and degenerative conditions (for example, myotonic dystrophy). To examine the effectiveness of interventions for oropharyngeal dysphagia in children with neurological impairment. We searched the following electronic databases in October 2011: CENTRAL 2011(3), MEDLINE (1948 to September Week 4 2011), EMBASE (1980 to 2011 Week 40)

Difficulties with swallowing may be both persistent and life threatening for the majority of those who experience it irrespective of age, gender, and race. The purpose of this review is to define oropharyngeal dysphagia and describe its relationship to cervical spine disorders and postural disturbances due to either congenital or acquired disorders. The etiology and diagnosis of dysphagia are analyzed, focusing on cervical spine pathology associated with dysphagia as severe cervical spine disorders and postural disturbances largely have been held accountable for deglutition disorders. Scoliosis, kyphosis–lordosis, and osteophytes are the primary focus of this review in an attempt to elucidate the link between cervical spine disorders and dysphagia. It is important for physicians to be knowledgeable about what triggers oropharyngeal dysphagia in cases of cervical spine and postural disorders. Moreover, the optimum treatment for dysphagia, including the use of therapeutic maneuvers during deglutition, neck exercises, and surgical treatment, is discussed.

Swallowing dysfunction is common after stroke. More than 50% of the 665 thousand stroke survivors will experience dysphagia acutely of which approximately 80 thousand will experience persistent dysphagia at 6 months. The physiologic impairments that result in post-stroke dysphagia are varied. This review focuses primarily on well-established dysphagia treatments in the context of the physiologic impairments they treat. Traditional dysphagia therapies including volume and texture modifications, strategies such as chin tuck, head tilt, head turn, effortful swallow, supraglottic swallow, super-supraglottic swallow, Mendelsohn maneuver and exercises such as the Shaker exercise and Masako (tongue hold) maneuver are discussed. Other more recent treatment interventions are discussed in the context of the evidence available. PMID:26484001

Background/objective Dysphagia following cervical spinal cord injury (SCI) can increase risk for pulmonary complications that may delay the rehabilitative process. The objective of this study was to identify risk factors for dysphagia after cervical SCI. Design Prospective cohort study. Methods Individuals with cervical SCI within 31 days of injury underwent a bedside swallow evaluation (BSE) followed by a videofluoroscopy swallow study (VFSS) within 72 hours of the BSE. Subjects were diagnosed as having dysphagia if they had positive findings in either BSE or VFSS. Results Twenty-nine patients (7 female and 22 male) were enrolled. Of these, 21 (72%) had high cervical tetraplegia (C4 or higher) and 8 (38%) had lower cervical tetraplegia. A tracheostomy was present in 18 (62%) patients; 15 (52%) subjects were on ventilators. Dysphagia was diagnosed in 12 (41%) subjects. Dysphagia was noted in 62% of the subjects with tracheostomy and 53% of the subjects on the ventilator, but only tracheostomy resulted in a statistically significant association with dysphagia (P = 0.047). All three subjects who had nasogastric tubes were diagnosed with dysphagia (P = 0.029). The relationships between dysphagia and gender, high versus low tetraplegia, presence of halo or collar, head injury, and ventilator use were not statistically significant, but age was a significant risk factor (P = 0.028). Conclusions Dysphagia is present in about 41% of individuals with acute tetraplegia. Only age, tracheostomy, and nasogastric tubes were identified as significant risk factors for dysphagia for individuals with tetraplegia. No relationship between dysphagia and level of SCI, spine surgery, collar, and ventilator use was found to exist. PMID:21528631

To examine the effects of the Intensive Dysphagia Rehabilitation approach on physiological and functional swallowing outcomes in adults with neurogenic dysphagia. Intervention study; before-after trial with 4-week follow-up through an online survey. Outpatient university clinics. A consecutive sample of subjects (N=10) recruited from outpatient university clinics. All subjects were diagnosed with adult-onset neurologic injury or disease. Dysphagia diagnosis was confirmed through clinical and endoscopic swallowing evaluations. No subjects withdrew from the study. Participants completed the 4-week Intensive Dysphagia Rehabilitation protocol, including 2 oropharyngeal exercise regimens, a targeted swallowing routine using salient stimuli, and caregiver participation. Treatment included hourly sessions twice per week and home practice for approximately 45 min/d. Outcome measures assessed pre- and posttreatment included airway safety using an 8-point Penetration Aspiration Scale, lingual isometric pressures, self-reported swallowing-related quality of life (QOL), and level of oral intake. Also, patients were monitored for adverse dysphagia-related effects. QOL and adverse effects were also assessed at the 4-week follow-up (online survey). The Intensive Dysphagia Rehabilitation approach was effective in improving maximum and mean Penetration Aspiration Scale scores (P<.05, η(2)=.8146 and P<.05, η(2)=.799708, respectively) and level of oral intake (P<.005, Cohen d=-1.387). Of the 5 patients who were feeding tube dependent initially, 2 progressed to total oral nutrition, and 2 progressed to partial oral nutrition. One patient remained tube dependent. QOL was significantly improved at the 4-week follow-up (95% confidence interval, 6.38-14.5; P<.00), but not at the posttreatment. No adverse effects were observed/reported. The Intensive Dysphagia Rehabilitation approach was safe and improved physiological and some functional swallowing outcomes in our sample; however

To characterize swallowing deficits in amyotrophic lateral sclerosis (ALS); investigate the delay in dysphagia onset; estimate correlations between dysphagia severity and patients' functional status; identify the symptom(s) most likely to predict dysphagia. A group of 49 consecutive patients with ALS, 14 with bulbar onset and 35 with spinal onset, underwent swallowing evaluation including bedside and fiberoptic endoscopic examination to detect dysphagia. Patients with dysphagia were more likely than those without to have bulbar onset ALS (P = 0.02); more severely impaired chewing (P = 0.01); and tongue muscle deficits (P = 0.001). The only variable measured at first examination significantly associated with dysphagia was a more than mild tongue muscle deficit. The only variable useful in predicting dysphagia was a chewing deficit. In 10 of the 49 patients studied, swallowing evaluation disclosed an impaired cough reflex. Dysphagia in patients with ALS correlates significantly with bulbar onset and with oral swallowing impairment. Fiberoptic swallowing evaluation is a useful tool for detecting swallowing deficits and laryngeal sensitivity in patients with ALS. An impaired cough reflex is an unexpected finding in many patients with ALS. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Esophageal dysphagia is a commonly reported symptom with various benign and malignant causes. Esophageal dysphagia can impede intake of oral medication, which often poses a major challenge for both patients and physicians. The best way to address this challenge depends of the cause of dysphagia. The pathophysiology of esophageal dysphagia is discussed, diagnostic tools to determine its cause are reviewed and recent developments in the treatment of esophageal dysphagia are discussed. Alternative options to administer medication in dysphagia are discussed and the appropriateness of them reviewed. Two ways can be followed to allow medication intake in patients with esophageal dysphagia, i.e. altering medication or resolving dysphagia. The latter is generally preferred, since esophageal dysphagia rarely only impedes medication intake. Esophageal resection is possible in more advanced esophageal cancer stages due to advances in neo-adjuvant therapy. Due to recent improvements in intraluminal radiotherapy, it can be expected that this will be the primary treatment in a palliative setting. Temporary self-expandable metal stent placement is a promising new alternative for bougienage in difficult-to-treat benign strictures.

Background Group A streptococcus (GAS) pharyngitis is associated with high rates of rheumatic heart disease (RHD) in developing countries. We sought to identify guidelines for empiric treatment of pharyngitis in low resource settings. To inform the design of GAS vaccines, we determined the emm types associated with pharyngitis among African schoolchildren. Methods Surveillance for pharyngitis was conducted among children 5 to 16 years of age attending schools in Bamako, Mali. Students were encouraged to visit a study clinician when they had a sore throat. Enrollees underwent evaluation and throat swab for isolation of GAS. Strains were emm typed by standard methods. Results GAS was isolated from 449 (25.5%) of the 1,759 sore throat episodes. Painful cervical adenopathy identified 403 children (89.8%) with GAS infection and was absent in 369 uninfected children (28.2%). Emm type was determined in 396 (88.2%) of the 449 culture-positive children; 70 types were represented and 14 types accounted for 49% of isolates. Based on the proportion of the 449 isolates bearing emm types included in the 30-valent vaccine (31.0%) plus non-vaccine types previously shown to react to vaccine-induced bactericidal antibodies (44.1%), the vaccine could protect against almost 75% of GAS infections among Bamako schoolchildren. Conclusions Two promising strategies could reduce RHD in low resource settings. Administering antibiotics to children with sore throat and tender cervical adenopathy could treat most GAS-positive children while reducing use of unnecessary antibiotics for uninfected children. Broad coverage against M types associated with pharyngitis in Bamako schoolchildren might be achieved with the 30-valent GAS vaccine under development. PMID:25356953

Elderly patients suffering from dysphagia, institutionalised either in hospital or nursing homes, have been studied. Etiology, characteristics and complications of dysphagia were studied as well as the most frequently used strategies to improve the management of swallowing disorders. A retrospective study of the complications of dysphagia found during the last 4 years in our hospital were conducted in addition to a cross-sectional study of the techniques used to manage dysphagia. A postal questionnaire was sent to all the registered nursing homes in the Valencian Community. Inhospital patients: 58% of physicians estimated that no less than 20% of patients under their care presented dysphagia. 13% of the total number of hospital diets were specific for swallowing disorders. All the patients suffering from dysphagia used a liquid thickener. Nursing Homes residents: 107 questionnaires were returned. This represents 7057 residents of which 3.6% were suffering from dysphagia. 54% of nursing homes have a specific diet for the management of dysphagia, 51% used nasogastric feeding and 30% consider PEG. The most frequent complications were 75% lung aspirations, 39% dehydration, 32% malnourishment and 31% pneumonia. Dysphagia is an important problem in elderly people. In our hospital there is a correct use of a dysphagia diet but it could be more widespread and further measures should be taken. Complications are frequent but are not correctly documented in the medical records. Nursing home residents have frequent and important complications when suffering dysphagia. Interventions towards a better management of dysphagia should be recommended and implemented.

Pharyngeal cavity and the gills are the target organ for the repellent action of pardaxin in shark.

Pardaxin, an active principle of the repellent secretion of the Red Sea flatfish, Pardachirus marmoratus, elicited severe struggling, mouth paralysis, and transient increase in urea leakage from the gills only when administered to the medium bathing the shark's pharyngeal cavity and gills. An apparatus was constructed which prevents a mixing of the outflow from shark's gills with water bathing its surface skin. It is concluded that in sharks the gills and/or the pharyngeal cavity are the target organ for the repellent action of pardaxin.

In order to be able to assess the level of awareness of swallowing disorders in Parkinson's disease (PD), a specific questionnaire was designed and validated: the Dysphapark questionnaire. A total of 470 persons with PD were asked whether they believe they have problems swallowing or not, and then they filled in a self-administered questionnaire that evaluates the effectiveness and safety of swallowing. The Dysphapark questionnaire was validated by means of Rasch analysis and classical psychometric methods. The safety and effectiveness dimensions of the Dysphapark fit the Rasch model well. The efficacy dimension showed significant differences for gender, length of the illness, awareness of dysphagia and length of meals. Significant differences were also found in the safety dimension for length and severity of illness, awareness of dysphagia, speech therapy and knowledge of thickening agents. Despite the fact that 90% of patients had problems concerning effectiveness and safety in swallowing, 79.45% were not aware that they suffered from dysphagia. The Dysphapark questionnaire is a suitable measure of dysphagia in PD, according to the Rasch analysis. A high proportion of patients with PD have dysphagia, although it has been observed that they have a low level of awareness of the condition, of the consequences it may have and of the possibility of using thickening agents. Given that some of the swallowing disorders in PD are asymptomatic and that the level of awareness of the disorder is low, we recommend including specific questionnaires as well as clinical and instrumental evaluation of dysphagia in clinical practice.

To identify symptoms, common diagnostic findings, pattern of treatments and referrals offered, and their efficacy in a group of patients with idiopathic functional dysphagia in an otolaryngology setting with multiple providers. Case series with chart review. Tertiary academic center. Following Mayo Clinic Institutional Review Board approval, a retrospective chart review was conducted of patients with dysphagia who had a videofluoroscopic swallow study between January 1, 2013, and April 30, 2015. Each patient's dysphagia symptomology, videofluoroscopic swallow study, flexible laryngoscopy, and medical chart were reviewed to identify the treatment paradigms that were utilized. Sixty-seven adult patients met the inclusion criteria. Abnormal laryngeal muscle tension was present in 97% of patients. Eighty-two percent of patients also demonstrated signs of laryngeal hyperresponsiveness. Nonspecific laryngeal inflammation was evident in 52% of patients. Twenty-seven patients were referred to speech-language pathology for evaluation. Thirteen patients completed a course of voice therapy directed toward unloading muscle tension. All 13 patients self-reported resolution of dysphagia symptoms. The study results suggest that laryngeal muscle tension may be a factor in the underlying etiology in patients with idiopathic functional dysphagia. We propose the diagnostic term muscle tension dysphagia to describe a subset of patients with functional dysphagia. Further prospective studies are needed to better evaluate potential gastroesophageal confounders in this group of patients and to identify an effective paradigm for treatment. In our limited series, speech-language pathology intervention directed toward unloading muscle tension appears effective. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

The fly pharyngeal sense organs lie at the transition between external and internal nutrient sensing mechanisms. Here, we investigate the function of pharyngeal sweet gustatory receptor neurons (GRNs), demonstrating that they express a subset of the nine previously identified sweet receptors and respond to stimulation with a panel of sweet compounds. We show that pox-neuro (poxn) mutants lacking taste function in the legs and labial palps have intact pharyngeal sweet taste, which is both necessary and sufficient to drive preferred consumption of sweet compounds by prolonging ingestion. Moreover, flies putatively lacking all sweet taste show little preference for nutritive or non-nutritive sugars in a short-term feeding assay. Together, our data demonstrate that pharyngeal sense organs play an important role in directing sustained consumption of sweet compounds, and suggest that post-ingestive sugar sensing does not effectively drive food choice in a simple short-term feeding paradigm.

Dysphagia in Parkinson's disease: a therapeutic challenge?

PubMed

Michou, Emilia; Hamdy, Shaheen

2010-06-01

This article focuses on the current status and research directions on swallowing disorders (dysphagia) in patients with Parkinson's disease (PD). Although epidemiological data are scarce, increased incidence of dysphagia in patients with PD leads to increased risk of mortality, secondary to aspiration pneumonia. Although studies show that aspiration pneumonia is a common cause of death in this group of patients, clinical practice lacks an evidence base and there is an increased need for randomized clinical trials. Importantly, the underlying mechanisms accounting for the progression of dysphagia in PD are still unclear. Furthermore, evidence shows that dopaminergic medication does not affect swallowing performance. Future research in the field is urgently needed and may result in improved management of dysphagia in patients with PD.

Dysphagia is considered an alarm symptom but detailed population-based data on dysphagia are lacking. We aimed to estimate in a representative USA Caucasian population, the prevalence of dysphagia and potential risk factors. A modified version of the previously validated Bowel Disease Questionnaire was mailed to a population-based cohort (n = 7640) of Olmsted County, MN. Dysphagia was measured by one validated question 'In the last year, how often have you had difficulty swallowing (a feeling that food sticks in your throat or chest)?' The medical records were reviewed for organic causes of dysphagia. The associations of reported frequency of dysphagia with potential risk factors were assessed using logistic regression models. The sex-specific, age-adjusted (US White 2000) prevalence for dysphagia experienced at least weekly was 3.0% (95% CI: 2.2, 3.7) in females and 3.0% (95% CI: 2.0, 4.0) in males. Those with frequent heartburn (OR = 5.9 [4.0, 8.6]) and acid regurgitation (OR = 10.6 [6.8, 16.6]) were significantly more likely to report frequent dysphagia. Proton pump inhibitor (PPI) use was significantly associated with frequent (3.1, 95% CI 2.2, 4.4) and infrequent dysphagia (1.5, 955 CI 1.3, 1.8). Gastro-esophageal reflux disease (GERD) was the most common diagnosis in those reporting dysphagia on the medical record; other organic explanations were rare and only found in the frequent dysphagia group. Frequent dysphagia is not rare in the community (3%), occurs in both women and men across all adult age groups, and is most likely to indicate underlying GERD. © 2014 John Wiley & Sons Ltd.

Dysphagia induces silent aspiration, which is a known risk factor for aspiration pneumonia in the elderly. Dysphagia is associated with impaired substance P secretion. Because nicergoline was recently reported to enhance substance P secretion, it may improve dysphagia by upregulating substance P; however, roles for nicergoline in this process have not been demonstrated. We therefore compared the effects of nicergoline on serum substance P and dysphagia with the effects of imidapril, an angiotensin-converting enzyme (ACE) inhibitor whose efficacy in improving dysphagia and preventing pneumonia has been previously demonstrated.We randomly assigned 60 elderly patients with both dysphagia and a previous history of pneumonia to receive either imidapril (5 mg/d; n = 30) or nicergoline (15 mg/d; n = 30) for 6 months. Primary outcomes were the effects of these drugs on the substance P level and dysphagia 4 weeks after the start of treatment. Secondary outcome was the effect of these drugs on pneumonia recurrence during the 6 months of treatment.Significant elevations of serum substance P were obtained by both medications after 4 weeks of treatment. Patients whose dysphagia was improved showed significantly increased serum levels of substance P. There was no statistically significant difference in the overall proportion of patients who showed improvements in dysphagia and pneumonia recurrence with imidapril or nicergoline treatment. Nicergoline, but not imidapril, seemed to be more effective at improving dysphagia and elevating serum substance P in patients with dementia.In conclusion, nicergoline has a comparable effect to ACE inhibitors for improving dysphagia. Nicergoline might be a novel regimen for the treatment of dysphagia in the elderly who are not treatable with ACE inhibitors.

Background: Dysphagia is frequently observed in patients with multiple sclerosis (MS). Dysphagia and its complications are common causes of morbidity and mortality in final stages of MS disease. This study aimed at determining the prevalence of dysphagia in Iranian patients with MS and identifying predictors associated with dysphagia. Methods: A total of 230 MS patients were enrolled in this cross-sectional study. Dysphagia was evaluated using Mann Assessment of Swallowing Ability (MASA). Demographic characteristics (age and gender), duration of the disease, disease course, and Expanded Disability Status Scale (EDSS) were recorded for all participants. Results: In total, dysphagia was found in 85 participants (37%) with mild to severe dysphagia (mild 50.6%; moderate 29.4%; and severe 20%). The logistic regression model demonstrated that disability status in EDSS (OR= 2.1; 95% CI 0.5-1.2) and disease duration (OR= 2.3; 95% CI 0.4-1.1) predicts a high risk for dysphagia in MS patients. Conclusion: Dysphagia is prevalent in Iranian patients with MS. Disability level and disease duration are significant predictors of dysphagia after MS.

Retrospective study. To analyze the reasons, clinical manifestation, risk factors, prevention, and treatment of dysphagia after operation of anterior cervical decompression and fusion (ACDF). Dysphagia is one of severe complications after ACDF. There were a few studies about reasons and prevention of dysphagia. We retrospectively reviewed medical charts of patients who underwent ACDF in our hospital from January 2012 to December 2012. Clinical symptom of dysphagia was recorded at the perioperative period and at the third and sixth month of the follow-up after surgery and assigned according to the Bazaz dysphagia score. We analyzed the reasons and risk factors leading to dysphagia and tried to find effective programs of prevention and treatment. There were 358 patients who underwent ACDF. Of 358 patients, 39 patients including 14 men and 25 women complained of dysphagia. The mean age was 46.8 years, with an age range of 38-67 years. Clinical manifestation of dysphagia included difficulty to swallow, pain during swallowing, sticky throat feeling, and choking. All the patients were followed up over 6 months. The incidences of dysphagia were 10.9%, 6.4%, and 2.7%, respectively, at 1-5 days, 3 months, and 6 months after surgery. There was no severe dysphagia at 3 months after surgery. Mild or moderate dysphagia slightly affected the quality of life. Logistic regression showed multilevel cervical spine, and high-level cervical spine surgeries are high-risk factors for postoperative dysphagia. Dysphagia is a common complication of ACDF. Causes of dysphagia include multilevel cervical spine and upper cervical spine surgeries. Use of methylprednisolone and careful operation can reduce the incidence and result in good prognosis.

Swallowing mechanism and neurogenic dysphagia in MS have been rarely studied by electromyographical (EMG) methods. This study aims to evaluate the presence of subclinical dysphagia in patients with mild multiple sclerosis (MS) using electrophysiological methods. A prospective study of 51 patients with relapsing remitting multiple sclerosis and 18 age-matched healthy adults was investigated. We used electromyography to measure the activity of the submental muscles during swallowing. Electrophysiological recordings of patients were obtained during relapse, after relapse, and at any time in remission period. Clinical dysphagia was found in 12% of MS patients, while electrophysiological swallowing abnormalities were encountered in 33% of patients. Subclinical dysphagia was determined in 35% of patients during an MS relapse, in 20% of patients after a relapse, and in 25% of all 51 patients in the remission period based on EMG findings. Duration of swallowing signal of submental muscles in all MS patients was found to be longer than in normal subjects (p = 0.001). During swallowing of 50 ml of sequential water, the compensatory respiratory cycles occurred more often in MS patients than normal subjects, especially during a relapse (p = 0.005). This is the first study investigating swallowing abnormalities and subclinical dysphagia from the electrophysiological aspect in MS patients with mild disability. The electrophysiological tests described in this study are useful to uncover subclinical dysphagia since they have the advantage of being rapid, easy to apply, non-invasive, and without risk for the patients.

Oropharyngeal Dysphagia after Anterior Cervical Spine Surgery: A Review

Anderson, Karen K.; Arnold, Paul M.

Study Design Review. Objective Postoperative oropharyngeal dysphagia is one of the most common complications following anterior cervical spine surgery (ACSS). We review and summarize recent literature in order to provide a general overview of clinical signs and symptoms, assessment, incidence and natural history, pathophysiology, risk factors, treatment, prevention, and topics for future research. Methods A search of English literature regarding dysphagia following anterior cervical spine surgery was conducted using PubMed and Google Scholar. The search was focused on articles published since the last review on this topic was published in 2005. Results Patients who develop dysphagia after ACSS show significant alterations in swallowing biomechanics. Patient history, physical examination, X-ray, direct or indirect laryngoscopy, and videoradiographic swallow evaluation are considered the primary modalities for evaluating oropharyngeal dysphagia. There is no universally accepted objective instrument for assessing dysphagia after ACSS, but the most widely used instrument is the Bazaz Dysphagia Score. Because dysphagia is a subjective sensation, patient-reported instruments appear to be more clinically relevant and more effective in identifying dysfunction. The causes of oropharyngeal dysphagia after ACSS are multifactorial, involving neuronal, muscular, and mucosal structures. The condition is usually transient, most often beginning in the immediate postoperative period but sometimes beginning more than 1 month after surgery. The incidence of dysphagia within one week after ACSS varies from 1 to 79% in the literature. This wide variance can be attributed to variations in surgical techniques, extent of surgery, and size of the implant used, as well as variations in definitions and measurements of dysphagia, time intervals of postoperative evaluations, and relatively small sample sizes used in published studies.

Abstract A multicenter retrospective study. The purpose of this study was to explore risk factors of dysphagia after anterior cervical surgery and factors affecting rehabilitation of dysphagia 2 years after surgery. Patients who underwent anterior cervical surgery at 3 centers from January 2010 to January 2013 were included. The possible factors included 3 aspects: demographic variables—age, sex, body mass index (BMI): hypertension, diabetes, heart disease, smoking, alcohol use, diagnose (cervical spondylotic myelopathy or ossification of posterior longitudinal ligament), preoperative visual analogue scale (VAS), Oswestry Disability Index (ODI), Japanese Orthopaedic Association (JOA), surgical-related variables—surgical option (ACDF, ACCF, ACCDF, or Zero profile), operation time, blood loss, operative level, superior fusion segment, incision length, angle of C2 to C7, height of C2 to C7, cervical circumference, cervical circumference/height of C2 to C7. The results of our study indicated that the rate of dysphagia at 0, 3, 6, 12, and 24 months after surgery was 20%, 5.4%, 2.4%, 1.1%, and 0.4%, respectively. Our results showed that age (58.8 years old), BMI (27.3 kg/m2), course of disease (11.6 months), operation time (103.2 min), blood loss (151.6 mL), incision length (9.1 cm), cervical circumference (46.8 cm), angle of C2 to C7 (15.3°), cervical circumference/height of C2 to C7 (4.8), preoperative VAS (7.5), and ODI (0.6) in dysphagia group were significantly higher than those (52.0, 24.6, 8.6, 88.2, 121.6, 8.6, 42.3, 12.6, 3.7, 5.6, and 0.4, respectively) in nondysphagia group; however, height of C2 to C7 (9.9 vs 11.7 cm) and preoperative JOA (8.3 vs 10.7) had opposite trend between 2 groups. We could also infer that female, smoking, diabetes, ossification of posterior longitudinal ligament, ACCDF, multilevel surgery, and superior fusion segment including C2 to C3 or C6 to C7 were the risk factors for dysphagia after surgery immediately.

With the recent emphasis on evidence-based practice and healthcare reform, understanding the cost of dysphagia management has never been more important. It is helpful for clinicians to understand and objectively report the costs associated with dysphagia when they advocate for their services in this economy. Having carefully estimated cost of illness, inputs are needed for cost-effectiveness analyses that help support the value of treatments. This study sought to address this issue by examining the 1-year cost associated with a diagnosis of dysphagia post-stroke in South Carolina. Furthermore, this study investigated whether ethnicity and residence differences exist in the cost of dysphagia post-stroke. Data on 3,200 patients in the South Carolina Medicare database from 2004 who had ICD-9 codes for ischemic stroke, 434 and 436, were retrospectively included in this study. Differences between persons with and without dysphagia post-stroke were compared with respect to age, gender, ethnicity, mortality, length of stay, comorbidity, rurality, discharge disposition, and cost to Medicare. Univariate analyses and a gamma-distributed generalized linear multivariable model with a log link function were completed. We found that the 1-year cost to Medicare for persons with dysphagia post ischemic stroke was $4,510 higher than that for persons without dysphagia post ischemic stroke when controlling for age, comorbidities, ethnicity, and proportion of time alive. Univariate analysis revealed that rurality, ethnicity, and gender were not statistically significantly different in comparisons of individuals with or without dysphagia post-stroke. Post-stroke dysphagia significantly increases post-stroke medical expenses. Understanding the expenditures associated with post-stroke dysphagia is helpful for optimal allocation and use of resources. Such information is needed to conduct cost-effectiveness studies.

AIM: Late unset of dysphagia due to vascular abnormalities is a rare condition. We aimed to present a case of right subclavian artery abnormalities caused dysphagia in the elderly. METHODS: A 68-year-old female was admitted with dysphagia seven months ago. Upper endoscopic procedures and routine examinations could not demonstrate any etiology. Multislice computed thorax tomography was performed for probable extra- esophagial lesions. RESULTS: Multislice computed thorax tomography showed right subclavian artery abnormality and esophagial compression with this aberrant artery. CONCLUSION: Causes of dysphagia in the elderly are commonly malignancies, strictures and/or motility disorders. If routine examinations and endoscopic procedures fail to show any etiology, rare vascular abnormalities can be considered in such patients. Multislice computed tomography is a usefull choice in such conditions. PMID:15285045

The fibrinogen-binding M1 protein reduces pharyngeal cell adherence and colonization phenotypes of M1T1 group A Streptococcus.

Group A Streptococcus (GAS) is a leading human pathogen producing a diverse array of infections from simple pharyngitis ("strep throat") to invasive conditions, including necrotizing fasciitis and toxic shock syndrome. The surface-anchored GAS M1 protein is a classical virulence factor that promotes phagocyte resistance and exaggerated inflammation by binding host fibrinogen (Fg) to form supramolecular networks. In this study, we used a virulent WT M1T1 GAS strain and its isogenic M1-deficient mutant to examine the role of M1-Fg binding in a proximal step in GAS infection-interaction with the pharyngeal epithelium. Expression of the M1 protein reduced GAS adherence to human pharyngeal keratinocytes by 2-fold, and this difference was increased to 4-fold in the presence of Fg. In stationary phase, surface M1 protein cleavage by the GAS cysteine protease SpeB eliminated Fg binding and relieved its inhibitory effect on GAS pharyngeal cell adherence. In a mouse model of GAS colonization of nasal-associated lymphoid tissue, M1 protein expression was associated with an average 6-fold decreased GAS recovery in isogenic strain competition assays. Thus, GAS M1 protein-Fg binding reduces GAS pharyngeal cell adherence and colonization in a fashion that is counterbalanced by SpeB. Inactivation of SpeB during the shift to invasive GAS disease allows M1-Fg binding, increasing pathogen phagocyte resistance and proinflammatory activities.

Immediate effects of thermal-tactile stimulation on timing of swallow in idiopathic Parkinson's disease.

Oropharyngeal dysphagia frequently presents in people with idiopathic Parkinson's disease (IPD). Clinical sequelae of dysphagia in this group include weight loss and aspiration pneumonia, the latter of which is the leading cause of hospital admissions and death in IPD. Thermal-tactile stimulation (TTS) is a sensory technique whereby stimulation is provided to the anterior faucial pillars to speed up the pharyngeal swallow. The effects of TTS on swallowing have not yet been investigated in IPD. The aim of this study was to investigate the immediate effects of TTS on the timing of swallow in a cohort of people with IPD and known oropharyngeal dysphagia. Thirteen participants with IPD and known dysphagia attended for videofluoroscopy during which standardised volumes of liquid barium and barium paste were administered preceding and immediately subsequent to TTS. The immediate effects of TTS on swallowing were examined using oral, pharyngeal, and total transit times and pharyngeal delay times as outcome measures. TTS significantly reduced median pharyngeal transit time on fluids (0.20 s, 95% CI = 0.12-0.28, p = 0.004) and on paste (0.3 s, 95% CI = 0.08-0.66, p = 0.01). Median total transit time was also reduced on fluids (0.48 s, 95% CI = 0.00-1.17, p = 0.049) and on paste (0.52 s, 95% CI = 0.08-1.46, p = 0.033). Median pharyngeal delay time was reduced on fluids (0.20 s, 95% CI = 0.12-0.34, p = 0.002). TTS did not significantly alter median oral transit time on either fluid or paste consistency. TTS significantly reduced temporal measures of the pharyngeal phase of swallowing in the IPD population. Significant results may be attributed to the role of sensory stimulation in improving motor function in IPD, with emphasis on the impaired glossopharyngeal and vagus nerves in this population. It is still unclear whether these findings will translate into a clinically beneficial effect.

Physicians specializing in dysphagia are needed in modern intensive care medicine. Long-term intubation is associated with aspiration and swallowing disorders. Early and standardised dysphagia management should be initiated during a patient's stay on intensive care unit. A clinically experienced, interdisciplinary team is required to provide optimal care for critically ill patients with dysphagia. Intensive care physicians should therefore know about basics in dysphagiology.

The Use of Brain Stimulation in Dysphagia Management.

Simons, Andre; Hamdy, Shaheen

2017-04-01

Dysphagia is common sequela of brain injury with as many as 50% of patients suffering from dysphagia following stroke. Currently, the majority of guidelines for clinical practice in the management of dysphagia focus on the prevention of complications while any natural recovery takes place. Recently, however, non-invasive brain stimulation (NIBS) techniques like transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) have started to attract attention and are applied to investigate both the physiology of swallowing and influences on dysphagia. TMS allows for painless stimulation of the brain through an intact skull-an effect which would normally be impossible with electrical currents due to the high resistance of the skull. By comparison, tDCS involves passing a small electric current (usually under 2 mA) produced by a current generator over the scalp and cranium external to the brain. Initial studies used these techniques to better understand the physiological mechanisms of swallowing in healthy subjects. More recently, a number of studies have investigated the efficacy of these techniques in the management of neurogenic dysphagia with mixed results. Controversy still exists as to which site, strength and duration of stimulation yields the greatest improvement in dysphagia. And while multiple studies have suggested promising effects of NIBS, more randomised control trials with larger sample sizes are needed to investigate the short- and long-term effects of NIBS in neurogenic dysphagia.

To explore the methods and results of surgical management for refractory dysphagia and aspiration. The clinical data of 24 refractory dysphagia and aspiration patients who accepted surgical management were retrospectively analysed. Twenty-four refractory dysphagia and aspiration patients accepted 26 operations between 2001 and 2014. Of the 26 operations, 17 were cricopharyngeal myectomy (CPM), 6 were scarectomy, 3 were laryngeal-tracheal separation. No severe complications occurred. Assessments of dysphagia were completed in 18 operations before and after operation. Aspiration scores of videofluoroscopic swallowing study (VFSS) were 4.50 [4.00;7.00] vs 2.00 [1.00; 3.25], P = 0.000; swallow dysfunction scroes of VFSS were 5.00 [4.00; 12.00] vs 1.00 [1.50; 10.00], P = 0.001; aspiration scores of fibroptic endoscopic evaluation of swallowing (FEES) were 4.00 [5.00; 7.00] vs 2.00 [1.75; 3.00], P = 0.000. But the surgical results for post radiotherapy dysphagia were not successful (n = 5): aspiration scores of VFSS were 7.00 [6.50; 8.00] vs 6.00 [2.00; 7.50], P = 0.109;swallow dysfunction scroes of VFSS were 12.00 [10.50; 12.00] vs 12.00 [7.50; 12.00], P = 0.180;aspiration scores of FEES were 7.00 [6.50; 8.00] vs 6.00 [2.00; 7.50], P = 0.109. Surgical management was effective for refractory dysphagia and aspiration, but the surgical indication selection should be strict.

Rheumatic fever has become uncommon in the United States while rapid diagnostic test technology for streptococcal antigens has improved. However, little is known about the effectiveness or cost-effectiveness of various strategies for managing pharyngitis caused by group A beta-hemolytic streptococcus (GAS) in U.S. adults. To examine the cost-effectiveness of several diagnostic and management strategies for patients with suspected GAS pharyngitis. Cost-effectiveness analysis. Published literature, including systematic reviews where possible. When costs were not available in the literature, we estimated them from our institution and Medicare charges. Adults in the general U.S. population. 1 year. Societal. Five strategies for the management of adult patients with pharyngitis: 1) observation without testing or treatment, 2) empirical treatment with penicillin, 3) throat culture using a two-plate selective culture technique, 4) optical immunoassay (OIA) followed by culture to confirm negative OIA test results, or 5) OIA alone. Cost per lost quality-adjusted life-days (converted to life-years where appropriate) and incremental cost-effectiveness. Empirical treatment was the least effective strategy at a GAS pharyngitis prevalence of 10% (resulting in 0.41 lost quality-adjusted life-day). Although the other four strategies had similar effectiveness (all resulted in about 0.27 lost quality-adjusted life-day), culture was the least expensive strategy. Results were sensitive to the prevalence of GAS pharyngitis: OIA followed by culture was most effective when GAS pharyngitis prevalence was greater than 20%. Observation was least expensive when prevalence was less than 6%, and empirical treatment was least expensive when prevalence was greater than 71%. The effectiveness of strategies was also very sensitive to the probability of anaphylaxis: When the probability of anaphylaxis was about half the baseline probability, OIA/culture was most effective; when the probability was

Anterior cervical hyperostosis may be a cause of dysphagia. For anterior cervical hyperostosis, medical or surgical treatments can be adhibited in view of the causative mechanisms and intensities of dysphagia. We report 3 cases of cervical hyperostosis-derived progressive dysphagia that underwent operation. Radiologic diagnosis and Video Fluoroscopic Swallowing Study were performed on the three patients for evaluation. One had history of recurrent aspiration pneumonia accompanied by weight loss, another complained of dysphagia only when swallowing pills, and the third experienced recurrence symptom with reossification. All patients reported gradual improvement of dysphagia immediately after their cervical osteophytes were resected through the anterior approach. In relation to postoperative improvement, however, they expressed different degrees of satisfaction according to severity of symptoms. Surgical treatment, performed for the anterior cervical hyperostosis-derived dysphagia, can immediately relieve symptoms of difficulty in swallowing. This might especially be considered as an appropriate treatment option for severe dysphagia. PMID:23185741

To assess geriatric patients' assessment of their clinical symptoms of dysphagia by means of a customized dysphagia screening tool and the usefulness of this assessment to health care professionals. The screening tool was distributed to an appropriate cohort and the entries correlated with results of standard speech-language pathology clinical assessments. A large long-term care/subacute rehabilitation facility. There were 199 new admissions screened. The patients included 74 (37.2%) males and 125 (60.8%) females. Patients' ages ranged from 50 to 98 with the mean age of 79.9 years. The screening tool used requires yes/no patient responses to 9 clinical indicators of dysphagia: difficulty keeping liquids in the mouth; coughing after drinking; shortness of breath while drinking; voice change after drinking; coughing after eating; shortness of breath after eating; food getting stuck in the mouth/throat when eating; voice change after eating; difficulty with saliva. After completing the questionnaire, the speech-language pathologist then conducted a standard bedside swallowing examination using the same 9 indicators. The findings suggest that although patients are less discriminating than clinicians in recognizing swallowing problems, the screening tool as a generalized indicator of potential for dysphagia is consistent and reliable. Individual items should not be used as indicators of dysphagia, but as a whole, the screening tool completed by patients is a reliable indicator of potential for dysphagia. Patients' awareness of their own swallowing impairment represents an important aspect of functional recovery. The findings of the study indicate that when patients self-identify a swallowing problem, the speech-language pathologist also identifies the existence of a problem, although not the same problem identified by the patient, with the same intensity or with the same manifestation.

Patients with chronic dysphagia are often in need of artificial nutrition; though being well balanced in terms of energy and vitamins, patients are at a high risk for the loss of resistance and body weight. Dysphagia also causes a severe drawback of the overall quality of life. This paper gives an overview of the present management of dysphagia from the point of view of otolaryngologists, head-neck-surgeons, phoniatricians, and medical speech-language-voice-pathologists. The physiology of swallowing and typical symptoms of dysphagia are first explained. Then the current most important diagnostic procedures as orofacial and laryngeal function analysis, video-endoscopy, and quantitative assessments, are discussed (part 1). This also includes considerations on bolus viscosity variation, postures, swallowing maneuvers, and sensory enhancement procedures, while actual options like botulinum toxin, passy-muir speaking valve, electromyographic biofeedback, and electrostimulation are also mentioned (part 2).

Purpose: To present initial results of a clinical trial of intensity-modulated radiotherapy (IMRT) aiming to spare the swallowing structures whose dysfunction after chemoradiation is a likely cause of dysphagia and aspiration, without compromising target doses. Methods and Materials: This was a prospective, longitudinal study of 36 patients with Stage III-IV oropharyngeal (31) or nasopharyngeal (5) cancer. Definitive chemo-IMRT spared salivary glands and swallowing structures: pharyngeal constrictors (PC), glottic and supraglottic larynx (GSL), and esophagus. Lateral but not medial retropharyngeal nodes were considered at risk. Dysphagia endpoints included objective swallowing dysfunction (videofluoroscopy), and both patient-reported and observer-rated scores. Correlations between dosesmore » and changes in these endpoints from pre-therapy to 3 months after therapy were assessed. Results: Significant correlations were observed between videofluoroscopy-based aspirations and the mean doses to the PC and GSL, as well as the partial volumes of these structures receiving 50-65 Gy; the highest correlations were associated with doses to the superior PC (p = 0.005). All patients with aspirations received mean PC doses >60 Gy or PC V{sub 65} >50%, and GSL V{sub 50} >50%. Reduced laryngeal elevation and epiglottic inversion were correlated with mean PC and GSL doses (p < 0.01). All 3 patients with strictures had PC V{sub 70} >50%. Worsening patient-reported liquid swallowing was correlated with mean PC (p = 0.05) and esophageal (p 0.02) doses. Only mean PC doses were correlated with worsening patient-reported solid swallowing (p = 0.04) and observer-rated swallowing scores (p = 0.04). Conclusions: These dose-volume-effect relationships provide initial IMRT optimization goals and motivate further efforts to reduce swallowing structures doses to reduce dysphagia and aspiration.« less

Study Objectives: To compare the components of the extracellular matrix in the lateral pharyngeal muscular wall in patients with and without obstructive sleep apnea (OSA). This may help to explain the origin of the increased collapsibility of the pharynx in patients with OSA. Design: Specimens from the superior pharyngeal constrictor muscle, obtained during pharyngeal surgeries, were evaluated using histochemical and immunohistochemical analyses to determine the fractional area of collagen types I and III, elastic fibers, versican, fibronectin, and matrix metalloproteinases 1 and 2 in the endomysium. Setting: Academic tertiary center. Patiens: A total of 51 nonobese adult patients, divided into 38 patients with OSA and 13 nonsnoring control subjects without OSA. Interventions: Postintervention study performed on tissues from patients after elective surgery. Measurements and Results: Pharyngeal muscles of patients with OSA had significantly more collagen type I than pharyngeal muscles in control subjects. Collagen type I was correlated positively and independently with age. The other tested components of the extracellular matrix did not differ significantly between groups. In a logistic regression, an additive effect of both the increase of collagen type I and the increase in age with the presence of OSA was observed (odds ratio (OR), 2.06; 95% confidence interval (CI), 1.17-3.63), when compared with the effect of increased age alone (OR, 1.11; 95% CI, 1.03-1.20). Conclusion: Collagen type I in the superior pharyngeal constrictor muscle was more prevalent in patients with OSA and also increased with age. It was hypothesized that this increase could delay contractile-relaxant responses in the superior pharyngeal constrictor muscle at the expiratory-inspiratory phase transition, thus increasing pharyngeal collapsibility.

Prefrontal cortex activity is modulated by flavor and taste stimuli and changes during swallowing. We hypothesized that changes in the modulation of prefrontal cortex activity by flavor and taste were associated with swallowing movement and evaluated brain activity during swallowing in patients with dysphagia. To evaluate prefrontal cortex activity in dysphagia patients during swallowing, change in oxidized hemoglobin (z-score) was measured with near-infrared spectroscopy while dysphagia patients and healthy controls swallowed sweetened/unsweetened and flavored/unflavored jelly. Total z-scores were positive during swallowing of flavored/unsweetened jelly and negative during swallowing of unflavored/sweetened jelly in controls but negative during swallowing of sweetened/unsweetened and flavored/unflavored jelly in dysphagia patients. These findings suggest that taste and flavor during food swallowing are associated with positive and negative z-scores, respectively. Change in negative and positive z-scores may be useful in evaluating brain activity of dysphagia patients during swallowing of sweetened and unsweetened food.

We aimed to investigate anxiety level of caregivers of neurological patients with dysphagia, and the relationship of patient-related factors to anxiety level of dysphagia caregivers. A total of 103 adult neurological patients with dysphagia (study group), 30 without dysphagia (control group), and their primary caregivers were included. Types of feeding, condition of dependency in eating and drinking, dysphagia duration, and history of previous dysphagia treatment were recorded for study group. In study group, the Turkish version of the Eating Assessment Tool-10 (T-EAT-10) was used to determine dysphagia symptom severity. Penetration and aspiration severity was determined with the penetration-aspiration scale (PAS). The Spielberger State-Trait Anxiety Inventory (STAI) that has two subscales including state anxiety (S-STAI) and trait anxiety (T-STAI) was used to determine anxiety level of caregivers. There was no difference between groups in terms of age, gender, weight, and height. The mean S-STAI was 42.56 ± 10.10 for the study group and 29.20 ± 6.64 for the control group (p < 0.001). The mean T-STAI was 44.81 ± 8.98 for the study group and 29.37 ± 6.46 for the control group (p < 0.001). Significant correlation was detected between only T-STAI and history of previous dysphagia treatment (p = 0.01, r = 0.25). No correlation was found between STAI (in terms of both S-STAI and T-STAI) and T-EAT-10, PAS, types of feeding, condition of dependency in eating and drinking, dysphagia duration (p > 0.05). Caregivers of neurological patients with dysphagia have greater anxiety level than caregivers of neurological patients without dysphagia.

This systematic review explores the effects of dysphagia treatment for Parkinson's disease. The review includes rehabilitative, surgical, pharmacologic, and other treatments. Only oropharyngeal dysphagia is selected for this literature search, excluding dysphagia due to esophageal or gastric disorders. The effects of deep brain stimulation on dysphagia are not included. In general, the literature concerning dysphagia treatment in Parkinson's disease is rather limited. Most effect studies show diverse methodologic problems. Multiple case studies and trials are identified by searching biomedical literature databases PubMed and Embase, and by hand-searching reference lists. The conclusions of most studies cannot be compared with one another because of heterogeneous therapy methods and outcome measures. Further research based on randomized controlled trials to determine the effectiveness of different therapies for dysphagia in Parkinson's disease is required.

Recurrent, prepubertal, vaginal infections are an uncommon, troublesome problem for the patient and her family. Failure of initial therapy to alleviate vulvovaginitis may be related to vulvar skin disease, foreign body, sexual abuse, pinworms, reactions to medications, anatomic anomalies, or allergies. This report describes a case of recurrent Streptococcus pyogenes vulvovaginitis secondary to presumed vaginal re-inoculation from pharyngeal colonization. A 4-yr-old presented with one year of culture proven, recurrent Streptococcus pyogenes vulvovaginitis. Her symptoms repeatedly resolved with penicillin therapy, but continued to recur following cessation of antibiotic therapy. Evaluation included physical examination, trans-abdominal pelvic ultrasound, and vaginoscopy which all revealed normal upper and lower genital tract anatomy. Both the patient and her mother demonstrated culture proven, Group A Streptococcus pharyngeal colonization. Because of the possibility of repeated inoculations of the vaginal area from the colonized pharynx, they were both treated for decolonization with a regimen of amoxicillin and rifampin for ten days. Following this therapy there was resolution of vaginal symptoms with no further recurrence. Follow-up pharyngeal culture done on both mother and child on their last visit were negative for Group A Streptococcus. This case demonstrated an unusual specific cause of recurrent vaginitis resulting from presumed self or maternal re-inoculation with group A beta-hemolytic streptococcus from pharyngeal colonization. Group A beta-hemolytic streptococcus are consistently sensitive to penicillin, but up to 25% of acute pharyngitis cases treated with penicillin having continued asymptomatic, bacterial carriage within the nasopharynx. Thus initial alleviation of symptoms in a patient with Group A beta-hemolytic vulvovaginitis treated with penicillin, can have continued asymptomatic pharyngeal colonization which can result in recurrence of the

Fluid thickening is a well-established management strategy for oropharyngeal dysphagia (OD). However, the effects of thickening agents on the physiology of impaired swallow responses are not fully understood, and there is no agreement on the degree of bolus thickening. To review the literature and to produce a white paper of the European Society for Swallowing Disorders (ESSD) describing the evidence in the literature on the effect that bolus modification has upon the physiology, efficacy and safety of swallowing in adults with OD. A systematic search was performed using the electronic Pubmed and Embase databases. Articles in English available up to July 2015 were considered. The inclusion criteria swallowing studies on adults over 18 years of age; healthy people or patients with oropharyngeal dysphagia; bolus modification; effects of bolus modification on swallow safety (penetration/aspiration) and efficacy; and/or physiology and original articles written in English. The exclusion criteria consisted of oesophageal dysphagia and conference abstracts or presentations. The quality of the selected papers and the level of research evidence were assessed by standard quality assessments. At the end of the selection process, 33 articles were considered. The quality of all included studies was assessed using systematic, reproducible, and quantitative tools (Kmet and NHMRC) concluding that all the selected articles reached a valid level of evidence. The literature search gathered data from various sources, ranging from double-blind randomised control trials to systematic reviews focused on changes occurring in swallowing physiology caused by thickened fluids. Main results suggest that increasing bolus viscosity (a) results in increased safety of swallowing, (b) also results in increased amounts of oral and/or pharyngeal residue which may result in post-swallow airway invasion, (c) impacts the physiology with increased lingual pressure patterns, no major changes in impaired

Background Dysphagia is considered an alarm symptom but detailed population-based data on dysphagia are lacking. We aimed to estimate in a representative US Caucasian population the prevalence of dysphagia and potential risk factors. Methods A modified version of the previously validated Bowel Disease Questionnaire was mailed to a population based cohort (n=7640) of Olmsted County, MN. Dysphagia was measured by one validated question “In the last year, how often have you had difficulty swallowing (a feeling that food sticks in your throat or chest)?” The medical records were reviewed for organic causes of dysphagia. The associations of reported frequency of dysphagia with potential risk factors were assessed using logistic regression models. Results The sex-specific, age-adjusted (US White 2000) prevalence for dysphagia experienced at least weekly was 3.0 % (95% CI: 2.2, 3.7) in females and 3.0 % (95% CI: 2.0, 4.0) in males. Those with frequent heartburn [OR=5.9 (4.0, 8.6)] and acid regurgitation [OR=10.6 (6.8, 16.6)] were significantly more likely to report frequent dysphagia. PPI use was significantly associated with frequent (3.1, 95% CI 2.2, 4.4) and infrequent dysphagia (1.5, 955 CI 1.3, 1.8). GERD was the most common diagnosis in those reporting dysphagia on the medical record; other organic explanations were rare and only found in the frequent dysphagia group. Conclusions Frequent dysphagia is not rare in the community (3%), occurs in both women and men across all adult age groups, and is most likely to indicate underlying GERD. PMID:25376877

Laryngo-pharyngeal mechano-sensitivity (LPMS) is involved in dysphagia, sleep apnea, stroke, irritable larynx syndrome and cough hypersensitivity syndrome among other disorders. These conditions are associated with a wide range of airway reflex abnormalities. However, the current device for exploring LPMS is limited because it assesses only the laryngeal adductor reflex during fiber-optic endoscopic evaluations of swallowing and requires a high degree of expertise to obtain reliable results, introducing intrinsic expert variability and subjectivity. We designed, developed and validated a new air-pulse laryngo-pharyngeal endoscopic esthesiometer with a built-in laser range-finder (LPEER) based on the evaluation and control of air-pulse variability determinants and on intrinsic observer variability and subjectivity determinants of the distance, angle and site of stimulus impact. The LPEER was designed to be capable of delivering precise and accurate stimuli with a wide range of intensities that can explore most laryngo-pharyngeal reflexes. We initially explored the potential factors affecting the reliability of LPMS tests and included these factors in a multiple linear regression model. The following factors significantly affected the precision and accuracy of the test (P < 0.001): the tube conducting the air-pulses, the supply pressure of the system, the duration of the air-pulses, and the distance and angle between the end of the tube conducting the air-pulses and the site of impact. To control all of these factors, an LPEER consisting of an air-pulse generator and an endoscopic laser range-finder was designed and manufactured. We assessed the precision and accuracy of the LPEER's stimulus and range-finder according to the coefficient of variation (CV) and by looking at the differences between the measured properties and the desired values, and we performed a pilot validation on ten human subjects. The air-pulses and range-finder exhibited good precision and

Oropharyngeal dysphagia is a disabling and undertreated symptom that often occurs in patients with sporadic inclusion body myositis (s-IBM). In this study, we examined the effect of botulinum neurotoxin A (BoNT-A) injections to the cricopharyngeus muscle (CPM) of patients with s-IBM and dysphagia. A single-center retrospective study involving 40 biopsy-proven s-IBM-patients treated in the District of Southwest Finland from 2000 to 2013. The incidence of dysphagia, rate of aspirations, rate of aspiration pneumonias and treatment results of dysphagia were analyzed. Patients treated for dysphagia were evaluated before and after surgery by video-fluoroscopy and/or using a questionnaire. Twenty-five of the 40 s-IBM patients (62.5%) experienced dysphagia. BoNT-A was injected a median of 2 times (range 1-7) in 12 patients with dysphagia. Before the injections 7 patients reported aspiration, none afterwards. The corresponding figures for aspiration pneumonia were 3 and 0. All of these patients had normal swallowing function 12months (median, range 2-60) after the last injection. BoNT-A injections to the CPM alleviate the dysphagia of s-IBM patients reversibly and appear to reduce the rate of aspiration effectively. Copyright © 2017 Elsevier B.V. All rights reserved.

Dysphagia is a common symptom that is important to recognise and appropriately manage, given that causes include life threatening oesophageal neoplasia, oropharyngeal dysfunction, the risk of aspiration, as well as chronic disabling gastroesophageal reflux (GORD). The predominant causes of dysphagia varies between cohorts depending on the interplay between genetic predisposition and environmental risk factors, and is changing with time. Currently in white Caucasian societies adopting a western lifestyle, obesity is common and thus associated gastroesophageal reflux disease is increasingly diagnosed. Similarly, food allergies are increasing in the west, and eosinophilic oesophagitis is increasingly found as a cause. Other regions where cigarette smoking is still prevalent, or where access to medical care and antisecretory agents such as proton pump inhibitors are less available, benign oesophageal peptic strictures, Barrett’s oesophagus, adeno- as well as squamous cell carcinoma are endemic. The evaluation should consider the severity of symptoms, as well as the pre-test probability of a given condition. In young white Caucasian males who are atopic or describe heartburn, eosinophilic esophagitis and gastroesophageal reflux disease will predominate and a proton pump inhibitor could be commenced prior to further investigation. Upper gastrointestinal endoscopy remains a valid first line investigation for patients with suspected oesophageal dysphagia. Barium swallow is particularly useful for oropharyngeal dysphagia, and oesophageal manometry mandatory to diagnose motility disorders. PMID:29097867

Mesodermal retinoic acid signaling regulates endothelial cell coalescence in caudal pharyngeal arch artery vasculogenesis

PubMed Central

Li, Peng; Pashmforoush, Mohammad; Sucov, Henry M.

2011-01-01

Disruption of retinoic acid signaling causes a variety of pharyngeal arch artery and great vessel defects, as well as malformations in many other tissues, including those derived from the pharyngeal endoderm. Previous studies implied that arch artery defects in the context of defective RA signaling occur secondary to pharyngeal pouch segmentation defects, although this model has never been experimentally verified. In this study, we examined arch artery morphogenesis during mouse development, and the role of RA in this process. We show in normal embryos that the arch arteries form by vasculogenic differentiation of pharyngeal mesoderm. Using various genetic backgrounds and tissue-specific mutation approaches, we segregate pharyngeal arch artery and pharyngeal pouch defects in RA receptor mutants, and show that RA signal transduction only in pharyngeal mesoderm is required for arch artery formation. RA does not control pharyngeal mesodermal differentiation to endothelium, but instead promotes the aggregation of endothelial cells into nascent vessels. Expression of VE-cadherin was substantially reduced in RAR mutants, and this deficiency may underlie the arch artery defects. The consequences of disrupted mesodermal and endodermal RA signaling were restricted to the 4th and 6th arch arteries and to the 4th pharyngeal pouch, respectively, suggesting that different regulatory mechanisms control the formation of the more anterior arch arteries and pouches.

The current cross-sectional study aimed to investigate risk factors for dysphagia in elderly individuals in aged care facilities. A total of 878 individuals from 42 aged care facilities were recruited for this study. The dependent outcome was speech therapist-determined swallowing function. Independent factors were Eating Assessment Tool score, oral motor assessment score, Mini-Mental State Examination, medical history, and various functional status ratings. Binomial logistic regression was used to identify independent variables associated with dysphagia in this cohort. Two statistical models were constructed. Model 1 used variables from case files without the need for hands-on assessment, and Model 2 used variables that could be obtained from hands-on assessment. Variables positively associated with dysphagia identified in Model 1 were male gender, total dependence for activities of daily living, need for feeding assistance, mobility, requiring assistance walking or using a wheelchair, and history of pneumonia. Variables positively associated with dysphagia identified in Model 2 were Mini-Mental State Examination score, edentulousness, and oral motor assessments score. Cognitive function, dentition, and oral motor function are significant indicators associated with the presence of swallowing in the elderly. When assessing the frail elderly, case file information can help clinicians identify frail elderly individuals who may be suffering from dysphagia.

Bilateral medial medullary infarct is a rare stroke syndrome and only a handful of cases have been described. Dysphagia as a manifestation of medullary infarcts is well recognized but often associated with lateral medullary infarct. Bilateral medial medullary infarcts are commonly associated with severe dysphagia in addition to a number of other signs and symptoms. We describe a patient who had bilateral medial medullary infarct with severe dysphagia in addition to quadriplegia and respiratory difficulty, and analyze infarct topography with respect to dysphagia, risk factors, vascular territories involved, and prognosis in view of previously reported cases.

Dysphagia was evaluated by using the Gugging Swallowing Screen (GUSS). We investigated the relationship of dysphagia with pneumonia, length of hospital stay and discharge destination and compared rates of favourable clinical outcome and mortality at 3 months between dysphagic patients and those without dysphagia. Results Dysphagia was diagnosed in 118 of 570 (20.7%) patients and persisted in 60 (50.9%) at hospital discharge. Thirty-six (30.5%) patients needed nasogastric tube because of severe dysphagia. Stroke severity rather than infarct location was associated with dysphagia. Dysphagic patients suffered more frequently from pneumonia (23.1% vs. 1.1%, p<0.001), stayed longer at monitored stroke unit beds (4.4±2.8 vs. 2.7±2.4 days; p<0.001) and were less often discharged to home (19.5% vs. 63.7%, p = 0.001) as compared to those without dysphagia. At 3 months, dysphagic patients less often had a favourable outcome (35.7% vs. 69.7%; p<0.001), less often lived at home (38.8% vs. 76.5%; p<0.001), and more often had died (13.6% vs. 1.6%; p<0.001). Multivariate analyses identified dysphagia to be an independent predictor of discharge destination and institutionalization at 3 months, while severe dysphagia requiring tube placement was strongly associated with mortality. Conclusion Dysphagia still affects a substantial portion of stroke patients and may have a large impact on clinical outcome, mortality and institutionalization. PMID:26863627

Food Culture, Preferences and Ethics in Dysphagia Management.

Kenny, Belinda

Adults with dysphagia experience difficulties swallowing food and fluids with potentially harmful health and psychosocial consequences. Speech pathologists who manage patients with dysphagia are frequently required to address ethical issues when patients' food culture and/ or preferences are inconsistent with recommended diets. These issues incorporate complex links between food, identity and social participation. A composite case has been developed to reflect ethical issues identified by practising speech pathologists for the purposes of illustrating ethical concerns in dysphagia management. The case examines a speech pathologist's role in supporting patient autonomy when patients and carers express different goals and values. The case presents a 68-year-old man of Australian/Italian heritage with severe swallowing impairment and strong values attached to food preferences. The case is examined through application of the dysphagia algorithm, a tool for shared decision-making when patients refuse dietary modifications. Case analysis revealed the benefits and challenges of shared decision-making processes in dysphagia management. Four health professional skills and attributes were identified as synonymous with shared decision making: communication, imagination, courage and reflection. © 2015 John Wiley & Sons Ltd.

Dysphagia: current reality and scope of the problem.

Clavé, Pere; Shaker, Reza

Dysphagia is a symptom of swallowing dysfunction that occurs between the mouth and the stomach. Although oropharyngeal dysphagia is a highly prevalent condition (occurring in up to 50% of elderly people and 50% of patients with neurological conditions) and is associated with aspiration, severe nutritional and respiratory complications and even death, most patients are not diagnosed and do not receive any treatment. By contrast, oesophageal dysphagia is less prevalent and less severe, but with better recognized symptoms caused by diseases affecting the enteric nervous system and/or oesophageal muscular layers. Recognition of the clinical relevance and complications of oesophageal and oropharyngeal dysphagia is growing among health-care professionals in many fields. In addition, the emergence of new methods to screen and assess swallow function at both the oropharynx and oesophagus, and marked advances in understanding the pathophysiology of these conditions, is paving the way for a new era of intensive research and active therapeutic strategies for affected patients. Indeed, a unified field of deglutology is developing, with new professional profiles to cover the needs of all patients with dysphagia in a nonfragmented way.

Objectives This study was designed to assess the accuracy of gastrointestinal symptoms, including abdominal pain, nausea, and vomiting, in the diagnosis of Group A streptococcal (GAS) pharyngitis in children and to determine differences in diagnostic accuracy in boys versus girls. Methods This retrospective cross-sectional study included 5,755 consecutive patients aged <15 years with fever in the electronic database at a primary care practice. Gastrointestinal symptoms were recorded in the database according to the International Classification of Primary Care codes, and the data were extracted electronically. The reference standard was GAS pharyngitis diagnosed with a rapid test. Patients with a clinical diagnosis of probable GAS pharyngitis were excluded from the primary analysis. Results Among the 5,755 children with fever, 331 (5.8%) were coded as having GAS pharyngitis, including 218 (65.9%) diagnosed with rapid tests and 113 (34.1%) clinically diagnosed with probable GAS pharyngitis. Among patients with fever and abdominal pain, rapid-test-confirmed GAS pharyngitis was significantly more common in boys (11/120, 9.2%) than in girls (3/128, 2.3%; p=0.026). The positive likelihood ratio of abdominal pain was 1.49 (95% CI =0.88–2.51): 2.41 (95% CI =1.33–4.36) in boys and 0.63 (95% CI =0.20–1.94) in girls. The positive likelihood ratio of nausea was 2.05 (95% CI =1.06–4.00): 2.74 (95% CI =1.28–5.86) in boys and 1.09 (95% CI =0.27–4.42) in girls. The association between abdominal pain and GAS pharyngitis was stronger in boys aged <6 years than in boys aged 6–15 years. Conclusion Abdominal pain and nausea were associated with GAS pharyngitis in boys, but not in girls. Abdominal pain and nausea may help determine the suitability of rapid tests in younger boys with fever and other clinical findings consistent with GAS pharyngitis, even in the absence of sore throat.

2014-01-01

Background and Purpose Spontaneous swallowing frequency has been described as an index of dysphagia in various health conditions. This study evaluated the potential of spontaneous swallow frequency analysis as a screening protocol for dysphagia in acute stroke. Methods In a cohort of 63 acute stroke cases swallow frequency rates (swallows per minute: SPM) were compared to stroke and swallow severity indices, age, time from stroke to assessment, and consciousness level. Mean differences in SPM were compared between patients with vs. without clinically significant dysphagia. ROC analysis was used to identify the optimal threshold in SPM which was compared to a validated clinical dysphagia examination for identification of dysphagia cases. Time series analysis was employed to identify the minimally adequate time period to complete spontaneous swallow frequency analysis. Results SPM correlated significantly with stroke and swallow severity indices but not with age, time from stroke onset, or consciousness level. Patients with dysphagia demonstrated significantly lower SPM rates. SPM differed by dysphagia severity. ROC analysis yielded a threshold of SPM ≤ 0.40 which identified dysphagia (per the criterion referent) with 0.96 sensitivity, 0.68 specificity, and 0.96 negative predictive value. Time series analysis indicated that a 5 to 10 minute sampling window was sufficient to calculate spontaneous swallow frequency to identify dysphagia cases in acute stroke. Conclusions Spontaneous swallowing frequency presents high potential to screen for dysphagia in acute stroke without the need for trained, available personnel. PMID:24149008

The goal of this study was to obtain the limit of dysphagia and the average volume per swallow in patients with mild to moderate Parkinson's disease (PD) but without swallowing complaints and in normal subjects, and to investigate the relationship between them. We hypothesize there is a direct relationship between these two measurements. The study included 10 patients with idiopathic PD and 10 age-matched normal controls. Surface electromyography was recorded over the suprahyoid muscle group. The limit of dysphagia was obtained by offering increasing volumes of water until piecemeal deglutition occurred. The average volume per swallow was calculated by dividing the time taken by the number of swallows used to drink 100 ml of water. The PD group showed a significantly lower dysphagia limit and lower average volume per swallow. There was a significantly moderate direct correlation and association between the two measurements. About half of the PD patients had an abnormally low dysphagia limit and average volume per swallow, although none had spontaneously related swallowing problems. Both measurements may be used as a quick objective screening test for the early identification of swallowing alterations that may lead to dysphagia in PD patients, but the determination of the average volume per swallow is much quicker and simpler.

Background and aims  Chemoradiotherapy for head and neck cancer (HNC) with/without laryngectomy commonly causes dysphagia. Pharyngoesophageal junction (PEJ) stricturing is an important contributor. We aimed to validate a functional lumen imaging probe (the EndoFLIP system) as a tool for quantitating pretreatment PEJ distensibility and treatment-related changes in HNC survivors with dysphagia and to evaluate the diagnostic accuracy of EndoFLIP-derived distensibility in detecting PEJ strictures. Methods  We studied 34 consecutive HNC survivors with long-term (> 12 months) dysphagia who underwent endoscopic dilation for suspected strictures. Twenty non-dysphagic patients undergoing routine endoscopy served as controls. PEJ distensibility was measured at endoscopy with the EndoFLIP system pre- and post-dilation. PEJ stricture was defined as the presence of a mucosal tear post-dilation. Results  PEJ stricture was confirmed in 22/34 HNC patients (65 %). During distension up to 60 mmHg, the mean EndoFLIP-derived narrowest cross-sectional area (nCSA) in HNC patients with strictures, without strictures, and in controls were 58 mm 2 (95 % confidence interval [CI] 22 to 118), 195 mm 2 (95 %CI 129 to 334), and 227 mm 2 (95 %CI 168 to 316), respectively. A cutoff of 114 mm 2 for the nCSA at the PEJ had perfect diagnostic accuracy in detecting strictures (area under the receiver operating characteristic curve = 1). In patients with strictures, a single session of dilation increased the nCSA by 29 mm 2 (95 %CI 20 to 37; P  < 0.001). In patients with no strictures, dilation caused no change in the nCSA (mean difference 13 mm 2 [95 %CI -4 to 30]; P  = 0.13). Conclusions  EndoFLIP is a highly accurate technique for the detection of PEJ strictures. EndoFLIP may complement conventional diagnostic tools in the detection of pharyngeal outflow obstruction. © Georg Thieme Verlag KG Stuttgart · New York.

Dysphagia associated with neurological disease is an important clinical manifestation in the diagnosis of injury that justifies the compression of the brainstem and lower cranial nerves. To emphasize the study of dysphagia in a patient with Chiari I malformation associated with syringomyelia in the absence of primary gastroenterological symptoms. We describe the case of a 62 year-old woman with oropharyngeal dysphagia of six years of evolution, cervicobrachialgia, ptosis and facial diplexia. Magnetic resonance imaging is an essential element for establishing the etiologic diagnosis of neurogenic dysphagia.

Rehabilitation Nutrition for Possible Sarcopenic Dysphagia After Lung Cancer Surgery: A Case Report.

Sarcopenic dysphagia is characterized by the loss of swallowing muscle mass and function associated with generalized loss of skeletal muscle mass and function. In this report, the authors describe a patient with possible sarcopenic dysphagia after lung cancer surgery and was treated subsequently by rehabilitation nutrition. A 71-year-old man with lung cancer experienced complications of an acute myocardial infarction and pneumonia after surgery. He was ventilated artificially, and a tracheotomy was performed. The patient received diagnoses of malnutrition, severe sarcopenia, and possible sarcopenic dysphagia. His dysphagia was improved by a combination of dysphagia rehabilitation including physical and speech therapy and an improvement in nutrition initiated by a nutrition support team. Finally, he no longer had dysphagia and malnutrition. Sarcopenic dysphagia should be considered in patients with sarcopenia and dysphagia. Rehabilitation nutrition using a combination of both rehabilitation and nutritional care management is presumptively useful for treating sarcopenic dysphagia.

Vertebral hyperostosis typically predominates at the thoracic spine and causes only minor symptoms. Involvement of the cervical spine may cause dysphagia due to pressure on the esophagus. We report three cases of dysphagia revealing cervical hyperostosis. The patients were 3 men aged 54-73 years. Dysphagia was moderate in 2 patients and severe in 1 patient who had lost 4 kg over 6 months. Stiffness of the neck with mild pain was present. One patient reported a neck injury in childhood and another had a brother and father with similar symptoms. Radiographs showed exuberant anterior cervical hyperostosis. Two patients also had hyperostotic changes at the thoracic spine and pelvis. The skin and neurological evaluation were normal. Findings were normal from standard blood tests (C-reactive protein, calcium, and vitamin D). Tests were negative for the HLA-B27 antigen in all 3 patients. Serum vitamin A levels were high, ranging from 894 to 1123 microg/L (normal, 489-720). None of the patients reported taking retinoids or having unusual eating habits. Dysphagia can result from anterior cervical hyperostosis. A role for hypervitaminosis A in the genesis of hyperostosis has long been suspected. In our patients, the absence of vitamin A supplementation suggests an abnormality in vitamin A metabolism.

Optimising medication for Parkinson's disease patients with dysphagia.

Patel, Krupa

2015-07-01

In addition to movement disorders, Parkinson's disease (PD) is associated with several nonmotor symptoms, including dysphagia (swallowing difficulties). Dysphagia can make the consumption of solid medicines difficult, which potentially contributes to the poor adherence that is common among people with PD. However, patients may be reluctant to admit that they experience dysphagia. Community nurses should actively enquire into swallowing difficulties among all patients, not only those with PD, and should work with pharmacists and other members of the multidisciplinary team to help optimise medication management to help improve adherence.

Electrophysiological Evaluation of Oropharyngeal Dysphagia in Parkinson’s Disease

Parkinson’s disease (PD) is a chronic, neurodegenerative movement disorder that typically affects elderly patients. Swallowing disorders are highly prevalent in PD and can have grave consequences, including pneumonia, malnutrition, dehydration and mortality. Neurogenic dysphagia in PD can manifest with both overt clinical symptoms or silent dysphagia. Regardless, early diagnosis and objective follow-up of dysphagia in PD is crucial for timely and appropriate care for these patients. In this review, we provide a comprehensive summary of the electrophysiological methods that can be used to objectively evaluate dysphagia in PD. We discuss the electrophysiological abnormalities that can be observed in PD, their clinical correlates and the pathophysiology underlying these findings. PMID:25360228

Interacting Genes Required for Pharyngeal Excitation by Motor Neuron Mc in Caenorhabditis Elegans

We studied the control of pharyngeal excitation in Caenorhabditis elegans. By laser ablating subsets of the pharyngeal nervous system, we found that the MC neuron type is necessary and probably sufficient for rapid pharyngeal pumping. Electropharyngeograms showed that MC transmits excitatory postsynaptic potentials, suggesting that MC acts as a neurogenic pacemaker for pharyngeal pumping. Mutations in genes required for acetylcholine (ACh) release and an antagonist of the nicotinic ACh receptor (nAChR) reduced pumping rates, suggesting that a nAChR is required for MC transmission. To identify genes required for MC neurotransmission, we screened for mutations that cause slow pumping but no other defects. Mutations in two genes, eat-2 and eat-18, eliminated MC neurotransmission. A gain-of-function eat-18 mutation, ad820sd, and a putative loss-of-function eat-18 mutation, ad1110, both reduced the excitation of pharyngeal muscle in response to the nAChR agonists nicotine and carbachol, suggesting that eat-18 is required for the function of a pharyngeal nAChR. Fourteen recessive mutations in eat-2 fell into five complementation classes. We found allele-specific genetic interactions between eat-2 and eat-18 that correlated with complementation classes of eat-2. We propose that eat-18 and eat-2 function in a multisubunit protein complex involved in the function of a pharyngeal nAChR. PMID:8601480

Management of acid-related disorders in patients with dysphagia.

PubMed

Howden, Colin W

2004-09-06

Dysphagia affects a large and growing number of individuals in the United States, particularly the elderly and those who are neurologically impaired. Swallowing difficulties may be due to age-related changes in oropharyngeal and esophageal functioning as well as central nervous system diseases such as stroke, Parkinson disease, and dementia. Among institutionalized individuals, dysphagia is associated with increased morbidity and mortality. An appreciation of the physiology of swallowing and the pathophysiology of dysphagia is necessary for proper patient management. Careful history, physical examination, and evaluation of radiologic and endoscopic studies should differentiate oropharyngeal and esophageal etiologies of dysphagia and distinguish mechanical (anatomic) disorders from functional (motor) disorders. A significant percentage of patients with dysphagia have concomitant acid-related disorders that are managed best with proton pump inhibitor (PPI) therapy. Three of the currently available PPIs are manufactured as capsules containing enteric-coated granules that may be mixed with soft foods or fruit juices before oral administration to those with swallowing difficulties. In addition, omeprazole and lansoprazole may be administered via gastrostomy or nasogastric feeding tubes as suspensions in sodium bicarbonate. Novel dosage formulations of lansoprazole that may be appropriate for patients with dysphagia include the commercially manufactured lansoprazole strawberry-flavored enteric-coated granules for suspension and lansoprazole orally disintegrating tablets.

- 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. - 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. - 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. - 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. - It was concluded that patients with postfundoplication dysphagia have similar water ingestion dynamics as patients with achalasia.

Background Existing clinical decision rules (CDR) to diagnose group A streptococcal (GAS) pharyngitis have not been validated in sub-Saharan Africa. We developed a locally applicable CDR while evaluating existing CDRs for diagnosing GAS pharyngitis in South African children. Methods We conducted a prospective cohort study and enrolled 997 children aged 3-15 years presenting to primary care clinics with a complaint of sore throat, and whose parents provided consent. Main outcome measures were signs and symptoms of pharyngitis, and a positive GAS culture from a throat swab. Bivariate and multivariate analyses were used to develop the clinical decision rule. In addition, the diagnostic effectiveness of six existing rules for predicting a positive culture in our cohort was assessed. Results 206 of 982 children (21%) had a positive GAS culture. Tonsillar swelling, tonsillar exudates, tender or enlarged anterior cervical lymph nodes, absence of cough and absence of rhinorrhea were associated with positive cultures in bivariate and multivariate analyses. Four variables (tonsillar swelling and one of tonsillar exudate, no rhinorrhea, no cough), when used in a cumulative score, showed 83.7% sensitivity and 32.2% specificity for GAS pharyngitis. Of existing rules tested, the McIsaac rule had the highest positive predictive value (28%), but missed 49% of the culture-positive children who should have been treated. Conclusion The new four-variable clinical decision rule for GAS pharyngitis (i.e., tonsillar swelling and one of tonsillar exudate, no rhinorrhea, no cough) outperformed existing rules for GAS pharyngitis diagnosis in children with symptomatic sore throat in Cape Town.

Recent data suggest that azithromycin may not be as effective as doxycycline in eradication of genital chlamydial infection. The aim of this study was to compare the eradication rate of pharyngeal Chlamydia trachomatis infection after treatment with azithromycin 1 g stat with that of doxycycline 100 mg twice a day for seven days. A prospective open-label observational study was conducted on patients with pharyngeal Chlamydia trachomatis diagnosed at Whittall Street Clinic, University Hospitals Birmingham, Birmingham, UK, between July 2012 and July 2013. We confirmed eradication of pharyngeal Chlamydia trachomatis with a negative test of cure. We treated all our patients with azithromycin 1 g stat until February 2013. At that stage, we offered doxycycline to patients with pharyngeal Chlamydia trachomatis A total of 398 patients (52 men, 346 women) were diagnosed with pharyngeal Chlamydia trachomatis during the study period. Of the 172 patients included in the final analysis, 78 were treated with azithromycin and 64 with doxycycline. Treatment failure was identified among 8/78 (10%) patients treated with azithromycin and 1/64 (2%) treated with doxycycline (absolute difference: 8 percentage points, 95% CI: 0-17%, p = 0.041). In our study, doxycycline 100 mg twice a day for seven days was associated with less treatment failure of oropharyngeal chlamydia compared with azithromycin 1 g stat Future randomised studies should investigate whether patients with pharyngeal Chlamydia trachomatis should be followed up with a test of cure when treated with azithromycin, or be treated with doxycycline. © The Author(s) 2016.

Hiatus Hernia as a Cause of Dysphagia.

PubMed

Philpott, Hamish; Sweis, Rami

2017-08-01

This review aims to discuss the putative relationship between hiatus hernia and dysphagia. Proposed mechanisms of dysphagia in patients with hiatus hernia are usually difficult to identify, but recent advances in technology (high-resolution manometry with or without concomitant impedance, ambulatory pH with impedance, videofluoroscopy, and the endoluminal functional lumen imaging probe (EndoFLIP)) and methodology (inclusion of swallows of various consistencies and volumes or shifting position during the manometry protocol) can help induce symptoms and identify the underlying disorder. Chronic reflux disease is often associated with hiatus hernia and is the most common underlying etiology. Dysmotility because of impaired contractility and vigor can occur as a consequence of repeated acid exposure from the acid pocket within the hernia, and the resultant poor clearance subsequently worsens this insult. As such, dysphagia appears to be more common with increasing hiatus hernia size. Furthermore, mucosal inflammation can lead to fibrotic stricture formation and in turn obstruction. On the other hand, there appears to be a difference in the pathophysiology of smaller sliding hernias, in that those with dysphagia are more likely to have extrinsic compression at the crural diaphragm as compared to those with reflux symptoms only. Sliding hiatus hernia, especially when small, does not commonly lead to dysmotility and dysphagia; however, in those patients with symptoms, the underlying etiology can be sought with new technologies and, in particular, the reproduction of normal eating and drinking during testing.

Transient postoperative dysphagia is not uncommon after antireflux surgery and usually runs a self-limiting course. However, a subset of patients report long-term dysphagia. The purpose of this study was to determine the risk factors for persistent postoperative dysphagia at 1 year after surgery. All patients who underwent antireflux surgery were entered into a prospectively maintained database. After obtaining institutional review board approval, the database was queried to identify patients who underwent primary antireflux surgery and were at least 1 year from surgery. Postoperative severity of dysphagia was evaluated using a standardized questionnaire (scale 0-3). Patients with scores of 2 or 3 were defined as having significant dysphagia. A total of 316 consecutive patients underwent primary antireflux surgery by a single surgeon. Of these, 219 patients had 1 year postoperative symptom data. Significant postoperative dysphagia at 1 year was reported by 19 (9.1%) patients. Thirty-eight patients (18.3%) required postoperative dilation for dysphagia. Multivariate logistic regression analysis identified preoperative dysphagia (odds ratio (OR), 4.4; 95% confidence interval (CI), 1.2-15.5; p = 0.023) and preoperative delayed esophageal transit by barium swallow (OR, 8.2; 95% CI, 1.6-42.2; p = 0.012) as risk factors for postoperative dysphagia. Female gender was a risk factor for requiring dilation during the early postoperative period (OR, 3.6; 95% CI, 1.3-10.2; p = 0.016). No correlations were found with preoperative manometry. There also was no correlation between a need for early dilation and persistent dysphagia at 1 year of follow-up (p = 0.109). Patients with preoperative dysphagia and delayed esophageal transit on preoperative contrast study were significantly more likely to report moderate to severe postoperative dysphagia 1 year after antireflux surgery. This study confirms that the manometric criteria used to define esophageal dysmotility are not reliable

Thickeners are used in post-stroke oropharyngeal dysphagia (OD) as a compensatory therapeutic strategy against aspirations. To compare the therapeutic effects of modified starch (MS) and xanthan gum (XG) thickeners on swallow safety and efficacy in chronic post-stroke OD patients using clinical and videofluoroscopic (VFS) assessment. Patients were studied by clinical assessment (volume-viscosity swallow test, V-VST) and VFS using 3 volumes (5, 10, 20 mL) and 3 viscosities (liquid, nectar and spoon thick), comparing MS and XG. We studied 122 patients (46MS, 76XG). (A) V-VST showed that both thickeners similarly improved safety of swallow. Prevalence of safe swallowing significantly increased with enhanced viscosity (P < 0.001 vs liquid), MS: 47.83 % at liquid, 84.93 % at nectar and 92.96 % at spoon thick; XG: 55.31 % at liquid, 77.78 % at nectar and 97.84 % at spoon thick. Patients on MS reported higher prevalence of pharyngeal residue at spoon-thick viscosities. (B) VFS: increasing bolus viscosity with either thickener increased prevalence of safe swallows (P < 0.001 vs liquid), MS: 30.25 % liquid, 61.07 % nectar and 92.64 % spoon thick; XG: 29.12 % liquid, 71.30 % nectar and 89.91 % spoon thick. Penetration-aspiration scale score was significantly reduced with increased viscosity with both thickeners. MS increased oral and pharyngeal residues at nectar and spoon-thick viscosities but XG did not. Timing of airway protection mechanisms and bolus velocity were not affected by either thickener. Increasing bolus viscosity with MS and XG thickeners strongly and similarly improved safety of swallow in chronic post-stroke OD by a compensatory mechanism; in contrast only MS thickeners increased oropharyngeal residue.

Dysphagia is the difficulty in swallowing and is often described by the patients as a 'perception' that there is an impediment to the normal passage of the swallowed material. It is frequently observed that there is an association of dysphagia with serious underlying disorders and warrants early evaluation. The current study aimed to determine the frequency of common endoscopic findings in patients presenting with oesophageal dysphagia. This cross-sectional descriptive study was carried out in the department of Gastroenterology, Ayub Medical College, Abbottabad, from October 2012 to April 2013. Consecutive patients with dysphagia were included in the study and were subjected to endoscopy. A total of 139 patients presenting with dysphagia were studied, 81 (58.3%) were males and 58 (41.7%) were females. The mean age was 52.41 ± 16.42. Malignant oesophageal stricture was the most common finding noted in 38 (27.3%) patients with 28 (73.7%) males and 23 (60.5%) patients among them were above the age of 50 years. It was followed by normal upper Gastrointestinal (GI) endoscopy in 29 (20.9%) patients and reflux esophagitis in 25 (18.0%) patients. Schatzki's ring was present in 14 (10.1%) patients; benign oesophageal strictures in 12 (8.6%) patients while achalasia was noted in 7 (5.0%) patients. 14(10.1%) patients had findings other than the ones mentioned above. Malignancies are a more common cause of dysphagia in our population and early diagnosis can result in proper treatment of many of these cases.

Use of alcohol-containing mouthwash has been found to have an inhibitory effect against pharyngeal gonorrhoea. The aim of this study was to investigate the association between self-reported mouthwash use and pharyngeal gonorrhoea detection among men who have sex with men (MSM). A cross-sectional survey was conducted between March 23, 2015, and June 30, 2015 among MSM attending the Melbourne Sexual Health Centre in Australia. Men who have sex with men were invited to complete a short questionnaire on mouthwash use and they were also tested for pharyngeal gonorrhoea by nucleic acid amplification test. Multivariate logistic regression was performed to examine the association between mouthwash use and pharyngeal gonorrhoea detection. Of the 823 MSM, pharyngeal gonorrhoea detection decreased significantly with increasing age group (≤24 years, 14.5%; 25-34 years, 10.7%; ≥35 years, 6.0%; ptrend = 0.003). The proportion reporting daily use of mouthwash increased significantly with increasing age group (from 10.1% to 14.5% to 19.8%; ptrend = 0.005). However, there was no significant association between pharyngeal gonorrhoea detection and daily use of mouthwash after adjusting for age, number of male sexual partners, human immunodeficiency virus status, and type of mouthwash use. Although the proportion of daily use of mouthwash increased with age, and pharyngeal gonorrhoea detection decreased with age, the association between self-reported mouthwash use and pharyngeal gonorrhoea detection by nucleic acid amplification test was not statistically significant.

Formal agreement studies on interpretation of the videofluoroscopic swallowing study (VFSS) procedure among speech-language pathologists, radiology house officers, and staff radiologists have not been pursued. Each of these professions participates in the procedure, interprets the examination, and writes separate reports on the findings. The aim of this study was to determine reliability of interpretation between and within the disciplines and to determine if structured training improved reliability. Thirteen speech-language pathologists (SLPs), ten diagnostic radiologists (RADs) and twenty-one diagnostic radiology house officers (HOs) participated in this study. Each group viewed 24 VFSS samples and rated the presence or absence of seven aberrant swallowing features as well as the presence of dysphagia and identification of oral dysphagia, pharyngeal dysphagia, or both. During part two, the groups were provided with a training session on normal and abnormal swallowing, using different VFSS samples from those in part one, followed by re-rating of the original 24 VFSS samples. A generalized estimating equations (GEE) approach with a binomial link function was used to examine each question separately. For each cluster of tests, as example, all pairwise comparisons between the three groups in the pretraining period, a Hochberg's correction for multiple testing was used to determine significance. A GEE approach with a binomial link function was used to compare the premeasure to postmeasure for each of the three groups of raters stratified by experience. The primary result revealed that the HO group scored significantly lower than the SLP and RAD group on identification of the presence of dysphagia (p = 0.008; p = 0.001, respectively), identification of oral phase dysphagia (p = 0.003; p = 0.001, respectively), and identification of both oral and pharyngeal phase dysphagia, (p = 0.014, p = 0.001, respectively) pretraining.

Deglutition, or the act of swallowing, allows food and fluids to move through the upper gastrointestinal tract. Difficulty swallowing, known as dysphagia, causes a host of complications for patients. Fluoroscopic evaluation of dysphagia enables appropriate diagnosis and treatment. This evaluation commonly is accomplished with a swallowing dysfunction study, also known as a modified barium swallow procedure. © 2018 American Society of Radiologic Technologists.

In children with severe cerebral palsy, the daily use of naso-pharyngeal airway, daily chest physiotherapy and adequate posture control markedly improve respiratory disorders and their consequent complications. Non-invasive ventiratory support methods such as nasal IPPV and nasal CPAP can be also effective. Enteral feeding through a naso-jejunal catheter can successfully manage feeding difficulty due to gastroesophageal reflux when surgical treatment is difficult. Exact assessment of aspiration by adequately performed video-fluoroscopic swallowing examination leads to national management of dysphagia. Tube feeding by intermittent oro-gastric catheterization combined with oral feeding is useful way in many dysphagic children. Surgical treatment for prevention of aspiration markedly improves the general condition. These treatments and managements have markedly improved the QOL, of children with severe cerebral palsy in many aspects. Cooperation of pediatricians, parents, school teachers and other community staffs is necessary for appropriate daily management of medical problems of these children.

Retrospective cohort study. This study investigates the incidence of long-term dysphagia in cervical disc arthroplasty, and anterior cervical discectomy and fusion (ACDF) patients. No long-term comparison of dysphagia between cervical arthroplasty and fusion patients has been published. Widely variable short-term postsurgical dysphagia rates have been reported. Cohorts for this study are patients with single-level cervical degenerative disc disease previously enrolled in a randomized clinical trial comparing cervical arthroplasty and ACDF. Subjective modified Bazaz Dysphagia Severity questionnaires were distributed to each patient at a minimum of 5 years postoperative for the long-term assessment. Dysphagia severity data were pooled to compare the rate of patients with dysphagia (grade>1) to asymptomatic (grade=1). In the arthroplasty cohort, 15 of 22 (68%) patients completed long-term swallowing questionnaires with no reports of dysphagia. Eighteen of 25 (72%) ACDF patients completed questionnaires, with 5 of 18 (28%) reporting dysphagia. This is a statistically significant difference (P=0.042) favoring lower rates of long-term dysphagia after cervical arthroplasty at an average interval of 7 years postoperative (range, 5.5-8.5 y). No significant difference between rates of self-reported short-term dysphagia was noted with 12% (3/25) and 9% (2/22) in the ACDF and arthroplasty groups, respectively (P=0.56). All short-term dysphagia cases in the arthroplasty cohort reported complete resolution of symptoms within 12 months postoperative. In the ACDF cohort, persistent symptoms at 7 years were noted in all responding patients. Three ACDF patients reported new late-onset, which was not noted in the arthroplasty cohort. To date, these findings represent the longest reported follow-up interval comparing rates of dysphagia between randomized cohorts of cervical arthroplasty and fusion patients. Our study suggests that cervical arthroplasty is less likely than ACDF to

This article reviews the most notable results of esophageal interventions for dysphagia and bleeding published in 2005. Long-term rubber tube placement was shown to be an interesting treatment option for difficult esophageal strictures. Two studies demonstrated that only 50% of patients who had undergone pneumatic dilation for achalasia were dysphagia-free after long-term follow-up. It was shown that patients with dysphagia from esophageal cancer should be treated by intraluminal radiotherapy (brachytherapy), whereas stent placement was preferable in those with a poor prognosis. Temporary stent placement is an option in patients undergoing radiotherapy for inoperable esophageal cancer to increase the dysphagia-free period. Two studies were published on the successful use of silicone-covered plastic stents for sealing of leaks after surgery of the esophagus. The optimal treatment for bleeding varices was confirmed to be endoscopic band ligation. A meta-analysis demonstrated that adding sclerotherapy to band ligation for secondary prophylaxis of bleeding varices had no effect on clinical outcome. In 2005, new techniques for the treatment of complicated strictures were presented. In addition, expanding indications for stents were reported. Finally, endoscopic band ligation was confirmed to be the most optimal technique for the treatment of varices.

Group A streptococcus (GAS) pharyngitis can cause serious complications such as rheumatic heart disease. The McIsaac sore throat score is a clinical prediction score used to improve the detection rate of GAS pharyngitis. We evaluated the validity of the McIsaac sore throat score in Southern Taiwan and compared our findings to those of other studies. We retrospectively analyzed chart records from children aged 3 to 15 years old who complained of fever and sore throat. They had throat cultures collected at the outpatient pediatric clinic of Fooyin University Hospital, located in Pingtung County, Taiwan during the period between January 2007 and January 2010. Clinical characteristics were reviewed, and sore throat score was analyzed. A total of 342 throat cultures met the inclusion criteria of sore throat and fever. The positive rate of GAS was 4.1%. Culture-positive cases were associated with higher odds for a skin rash [adjusted odds ratio (AOR): 14.66, 95% confidence interval (CI): 4.63-46.40, p < 0.001), lower odds for cough (AOR: 0.19, 95% CI: 0.04-0.85, p = 0.030) and having a runny nose (AOR: 0.22, 95% CI: 0.05-0.99, p = 0.048). The most common physical sign was scarlet fever rash (AOR: 57.35, 95% CI: 15.45-212.98, p < 0.001). A McIsaac score of 5 had a sensitivity of 71%, specificity of 70%, and a positive predictive value of only 9.3%. Pediatric streptococcal pharyngitis in Southern Taiwan is uncommon. Diagnosis of GAS pharyngitis based on the McIsaac sore throat score is unreliable among pediatric patients with febrile pharyngitis in Southern Taiwan. Copyright © 2012. Published by Elsevier B.V.

Group A streptococcus (GAS) is the most common bacterial cause of sore throat. School-age children bear the highest burden of GAS pharyngitis. Accurate diagnosis is difficult: the majority of sore throats are viral in origin, culture-based identification of GAS requires 24-48 hours, and up to 15% of children are asymptomatic throat carriers of GAS. The aim of this study was to develop a quantitative polymerase chain reaction (qPCR) assay for detecting GAS pharyngitis and assess its suitability for clinical diagnosis. Pharyngeal swabs were collected from children aged 3-18 years (n = 91) and adults (n = 36) located in the Melbourne area who presented with sore throat. Six candidate PCR assays were screened using a panel of reference isolates, and two of these assays, targeting speB and spy1258, were developed into qPCR assays. The qPCR assays were compared to standard culture-based methods for their ability to detect GAS pharyngitis. GAS isolates from culture positive swabs underwent emm-typing. Clinical data were used to calculate McIsaac scores as an indicator of disease severity. Twenty-four of the 127 samples (18.9%) were culture-positive for GAS, and all were in children (26%). The speB qPCR had 100% sensitivity and 100% specificity compared with gold-standard culture, whereas the spy1258 qPCR had 87% sensitivity and 100% specificity. Nine different emm types were found, of which emm 89, 3, and 28 were most common. Bacterial load as measured by qPCR correlated with culture load. There were no associations between symptom severity as indicated by McIsaac scores and GAS bacterial load. The speB qPCR displayed high sensitivity and specificity and may be a useful tool for GAS pharyngitis diagnosis and research.

Prolonged obstruction at the level of the lower esophageal sphincter is associated with a dilated, poorly contractile esophagus. The association between prolonged obstruction at the level of the upper esophageal sphincter (UES) and dilation and diminished contractility of the pharynx is uncertain. The purpose of this investigation was to evaluate the association between prolonged obstruction at the level of the UES and dilation and diminished contractility of the pharynx. Case-control study. The fluoroscopic swallow studies of all persons with cricopharyngeus muscle dysfunction (CPD) diagnosed between January 1, 2006 and December 31, 2008 were retrospectively reviewed from a clinical database. Three categories of CPD were defined: nonobstructing cricopharyngeal bars (CPBs), obstructing CPBs, and Zenker diverticulum (ZD). The primary outcome measure was the pharyngeal constriction ratio (PCR), a surrogate measure of pharyngeal strength on fluoroscopy. Secondary outcome measures included pharyngeal area in the lateral fluoroscopic view and UES opening. The outcome measures were compared between groups and to a cohort of nondysphagic age- and gender-matched controls with the analysis of variance. A total of 100 fluoroscopic swallow studies were evaluated. The mean age (+ or -standard deviation) of the cohort was 70 years (+ or -10 years). Thirty-six percent were female. The mean PCR progressively increased, indicating diminishing pharyngeal strength, from the normal (0.08), to the nonobstructing CPB (0.13), to the obstructing CPB (0.22), to the ZD group (0.28) (P < .001 with trend for linearity). There was a linear increase in pharyngeal area from the normal (8.75 cm(2)) to the nonobstructing CPB (10.00 cm(2)), to the obstructing CPB (10.46 cm(2)), to the ZD group (11.82 cm(2)) (P < .01 with trend for linearity). The data suggest that there is an association between cricopharyngeus muscle dysfunction and progressive dilation and weakness of the pharynx. Laryngoscope

The impressive morphological diversification of vertebrates was achieved in part by innovation and modification of the pharyngeal skeleton. Extensive fate mapping in amniote models has revealed a primarily cranial neural crest derivation of the pharyngeal skeleton. Although comparable fate maps of amphibians produced over several decades have failed to document a neural crest derivation of ventromedial elements in these vertebrates, a recent report provides evidence of a mesodermal origin of one of these elements, basibranchial 2, in the axolotl. We used a transgenic labeling protocol and grafts of labeled cells between GFP+ and white embryos to derive a fate map that describes contributions of both cranial neural crest and mesoderm to the axolotl pharyngeal skeleton, and we conducted additional experiments that probe the mechanisms that underlie mesodermal patterning. Our fate map confirms a dual embryonic origin of the pharyngeal skeleton in urodeles, including derivation of basibranchial 2 from mesoderm closely associated with the second heart field. Additionally, heterotopic transplantation experiments reveal lineage restriction of mesodermal cells that contribute to pharyngeal cartilage. The mesoderm-derived component of the pharyngeal skeleton appears to be particularly sensitive to retinoic acid (RA): administration of exogenous RA leads to loss of the second basibranchial, but not the first. Neural crest was undoubtedly critical in the evolution of the vertebrate pharyngeal skeleton, but mesoderm may have played a central role in forming ventromedial elements, in particular. When and how many times during vertebrate phylogeny a mesodermal contribution to the pharyngeal skeleton evolved remain to be resolved. © 2015 Wiley Periodicals, Inc.

The opening session of the 2nd International Conference on Oropharyngeal Dysphagia featured a series of invited talks reviewing the definition of dysphagia, its prevalence and its pathophysiology. The discussion arising from these talks focused heavily on the current underrecognition of dysphagia as a significant concern for older adults, particularly those over 75. The burdens associated with dysphagia in this sector of the population were recognized to be substantial, both in social/psychological terms and in terms of economic consequences for the healthcare system. The importance of developing swallow screening protocols as a routine method for the early identification of dysphagia and aspiration was explored. The idea of launching political initiatives aimed at increasing awareness and the utilization of appropriate dysphagia healthcare codes was also discussed. Copyright © 2012 S. Karger AG, Basel.

Sarcopenic dysphagia is characterized by difficulty swallowing due to a loss of whole-body skeletal and swallowing muscle mass and function. However, no study has reported on swallowing muscle mass and quality in patients with sarcopenic dysphagia. To compare the differences in swallowing muscle mass and quality between sarcopenic and nonsarcopenic dysphagia. A cross-sectional study was performed in 55 older patients, who had been recommended to undergo dysphagia assessment and/or rehabilitation. Sarcopenic dysphagia was diagnosed using a diagnostic algorithm for sarcopenic dysphagia. The thickness and area of tongue muscle and geniohyoid muscle (coronal plane and sagittal plane), and the echo-intensity of the tongue and geniohyoid muscles were examined by ultrasound. The study participants included 31 males and 24 females (mean age of 82 ± 7 years), with 14 having possible sarcopenic dysphagia, 22 probable sarcopenic dysphagia, and 19 without sarcopenic dysphagia. The group with sarcopenic dysphagia had a significantly lower cross-sectional area and area of brightness of the tongue muscle than that observed in the group without sarcopenic dysphagia. The most specific factor for identifying the presence of sarcopenic dysphagia was tongue muscle area (sensitivity, 0.389; specificity, 0.947; cut-off value, 1536.0), while the factor with the highest sensitivity was geniohyoid muscle area brightness in sagittal sections (sensitivity, 0.806; specificity, 0.632; cut-off value, 20.1). Multivariate logistic regression analysis showed that the area of the tongue muscle and its area of brightness were independent risk factors for sarcopenic dysphagia. However, geniohyoid sagittal muscle area and area of brightness showed no significant independent association with sarcopenic dysphagia. Tongue muscle mass in patients with sarcopenic dysphagia was smaller than that in patients without the condition. Sarcopenic dysphagia was also associated with increased intensity of the

Although the presence of dysphagia is a key determinant of nutritional status among older adults, few studies have focused on the association between malnutrition and dysphagia risk in community-dwelling frail older adults. This study estimated the prevalence of malnutrition and quantified the association between malnutrition and dysphagia risk among community-dwelling older Japanese adults requiring long-term care. Cross-sectional study. This study was conducted with the cooperation of the Japan Dental Association and local dental associations in all 47 prefectures from January to February 2012. Individuals aged ≥65 years capable of oral nutrient intake who were living at home and receiving home dental care and treatment. Individual demographic characteristics and factors associated with health loss-related functional decline were obtained through interviews by home-visit dentists and self-administered questionnaires. Nutritional status and dysphagia risk were evaluated using the Mini Nutritional Assessment Short Form and the Dysphagia Risk Assessment for the Community-dwelling Elderly. Among 874 respondents (345 men and 529 women), 24.6% were malnourished, 67.4% were at risk of malnutrition, and 8.0% were well nourished. Dysphagia risk was related to an increased likelihood of malnutrition at an old age, even after adjusting for covariates (PR = 1.30, 95% CI = 1.01-1.67). Malnutrition is highly prevalent among community-dwelling frail older adults, and dysphagia risk is independently associated with malnutrition. Dysphagia may be an important predictor of malnutrition progression in aged populations.

High-resolution manometry (HRM) has been applied to assess esophageal motility disorders. However, the frequency and types of motility disorders in patients with dysphagia, which are frequently seen in clinical practice, are not clear. We evaluated latent esophageal motility disorders associated with dysphagia. The study included patients without erosive esophageal mucosal damage and with dysphagia symptoms refractory to at least 8 weeks of standard-dose proton pump inhibitors. After enrolment, HRM was used to evaluate for esophageal motility disorder based on the Chicago classification. Esophageal motility disorder was found in 58 of 100 patients and was classified based on the causes: achalasia (13%), esophagogastric junction outflow obstruction (16%), distal esophageal spasms (3%), weak peristalsis (14%), frequently failed peristalsis (5%), and hypertensive peristalsis (7%). Primary esophageal motility disorder was found in approximately 50% of cases in dysphagia patients. Therefore, esophageal motility disorder is not an uncommon condition and should be sought for in order to elucidate precisely the cause of dysphagia. © 2017 S. Karger AG, Basel.

Guidelines advocate screening all acute stroke patients for dysphagia. However, limited data are available regarding how many and which patients are screened and how failing a swallowing screen affects patient outcomes. We sought to evaluate predictors of receiving dysphagia screening after acute ischemic stroke and outcomes after failing a screening test. We used the Ontario Stroke Registry from April 1, 2010, to March 31, 2013, to identify patients hospitalized with acute ischemic stroke and determine predictors of documented dysphagia screening and outcomes after failing the screening test, including pneumonia, disability, and death. Among 7171 patients, 6677 patients were eligible to receive dysphagia screening within 72 hours, yet 1280 (19.2%) patients did not undergo documented screening. Patients with mild strokes were significantly less likely than those with more severe strokes to have documented screening (adjusted odds ratio, 0.51; 95% confidence interval [CI], 0.41-0.64). Failing dysphagia screening was associated with poor outcomes, including pneumonia (adjusted odds ratio, 4.71; 95% CI, 3.43-6.47), severe disability (adjusted odds ratio, 5.19; 95% CI, 4.48-6.02), discharge to long-term care (adjusted odds ratio, 2.79; 95% CI, 2.11-3.79), and 1-year mortality (adjusted hazard ratio, 2.42; 95% CI, 2.09-2.80). Associations were maintained in patients with mild strokes. One in 5 patients with acute ischemic stroke did not have documented dysphagia screening, and patients with mild strokes were substantially less likely to have documented screening. Failing dysphagia screening was associated with poor outcomes, including in patients with mild strokes, highlighting the importance of dysphagia screening for all patients with acute ischemic stroke. © 2017 American Heart Association, Inc.

A detailed knowledge of dysphagia outcomes in lateral medullary infarct (LMI) patients would enable proper establishment of swallowing therapy goals and strategies. However, little is known about the impact of infarct location on dysphagia outcomes in patients with LMI. Twenty patients with rostral LMI (rostral group) and 20 patients with caudal LMI (caudal group) participated in the study. All patients underwent swallowing therapy, which included compensatory treatments and strengthening exercises, for >3 months. Dysphagia evaluation was performed twice (during the subacute stage and six months after stroke onset) using videofluoroscopic swallowing studies. Dysphagia degree was assessed using the functional dysphagia scale (FDS), the penetration-aspiration scale (PAS) and the American Speech-Language-Hearing Association (ASHA) National Outcome Measurement System (NOMS) swallowing scale. In the subacute stage, the rostral group had significantly higher FDS and PAS scores and a significantly lower ASHA NOMS score than the caudal group. Patients from both groups showed significant improvement from the initial evaluation to the six-month evaluation. There were no significant differences in these scale scores between the two groups at the six-month evaluation. In the subacute stage, patients in the rostral group had more severe dysphagia than those in the caudal group. Dysphagia improved in both groups after 3-6 months of swallowing therapy. At six months after onset, there were no significant differences in dysphagia severity between the two groups. Recovery from dysphagia after LMI was observed regardless of the infarct location.

The transient dysphagia after fundoplication is common and most often disappears until six weeks postoperatively. Analyze a group of patients who presented late and persistent dysphagia postoperatively. Forty-one patients after Nissen fundoplication, 14 male and 27 female, mean age 48 year, were evaluated based on medical history, esophagogastroduodenoscopy, contrast radiographic examination and esophageal manometry. The results were compared with another 19 asymptomatic individuals. Contrast radiographic examination of the esophagus revealed in six cases delayed emptying, characterizing that four patients had achalasia and two diffuse spasm of the esophagus. Esophageal manometry showed that maximal expiratory pressure of the lower sphincter ranged from 10 to 38 mmHg and mean respiratory pressure from 14 to 47 mmHg, values similar to controls. Residual pressure ranged from 5 to 31 mmHg, and 17 patients had the same values as the control group. The residual pressure of the lower sphincter was higher and statistically significant in patients with dysphagia compared with those operated without dysphagia. Future studies individualizing and categorizing each motility disorder, employing other techniques of manometry, and the analysis of the residual pressure may contribute to understand of persistent dysphagia in the postoperative fundoplication.

Protracted dysphagia and bloating are potential troublesome side effects following Nissen fundoplication. The aim of this study was to evaluate the effects of conversion from Nissen to Toupet on dysphagia and bloating. The study used a retrospective chart review of all patients who had undergone conversion from Nissen to Toupet between 2001 and 2014. Endpoints were to determine the effect of conversion on dysphagia, bloating, and reflux control. Twenty-five patients underwent conversion at a median of 3.7 years (1.4-10.5) after initial fundoplication. Indications were dysphagia in 19 (76%) and bloating syndrome in 6 (24%) patients. The median operative time was 104 min (86-146). There were no serious complications or mortality. Median follow-up was 27 months (0.8-130). Dysphagia was relieved in 16 (84%) and bloating in all 6 patients. Two patients developed reflux requiring a redo-Nissen. Two patients had persistent dysphagia and required endoscopic dilation. The GERD-HRQL post-conversion showed a median score of 5 (3-13). Conversion relieved dysphagia in 84% and bloating in 100%. Significant recurrence of GERD was rare. Given the absence of serious complications, conversion should be considered in patients with severe bloating or dysphagia.

Dysphagia is a severe complication in critically ill patients and affects more than half the patients in an intensive care unit. Dysphagia also has a strong impact on morbidity and mortality. Risk factors for the development of dysphagia are neurological diseases, age >55-70 years, intubation >7 days and sepsis. With increasing numbers of long-term survivors chronic dysphagia is becoming an increasing problem. There is not much knowledge on the influence of specific diseases, including the direct impact of sepsis on the development of dysphagia. Fiberoptic evaluation of swallowing is a standardized tool for bedside evaluation, helping to plan swallowing training during the acute phase and to decrease the rate of chronic dysphagia. For evaluation of chronic dysphagia even more extensive diagnostic tools as well as several options of stepwise rehabilitation using restitution, compensation and adaption strategies for swallowing exist. Currently it seems that these options are not being sufficiently utilized. In general, there is a need for controlled clinical trials analyzing specific swallowing rehabilitation concepts for former critically ill patients and long-term survivors.

To evaluate the efficacy of teacher tablets in the treatment of pharyngitis. One hundred and thirty six patients with acute pharyngitis or chronic pharyngitis in attack were randamly divided into two groups: treated group (n=68), the patients were given teacher tablets for 7 days, control group (n=68), the patients were given Qinlian capsule for 7 days. Before and after the experimental medicine-taking test, general condition, clinical symptoms and features of examinations on laryngo-pharynx, throat swab bacterial culture were measured. After 7 day medicine-taking experiment, teacher tablets can improve clinical symptoms (at an efficacy rate of more than 60%) and features (at an efficacy rate of more than 80%) of laryngopharynx, in treated group, the inhibition ratios of alpha streptococcus, neisseria and staphylococcus aureus are more than 50%. There are no significant difference between treated group and control groups in those detected index. Teacher tablets is effective for pharyagitis.

Upper airway nerve and muscle damage associated with obstructive sleep apnea may impair the strength and dynamics of pharyngeal and esophageal contractions during swallowing. To evaluate the presence of alterations in pharyngoesophageal manometry in patients with obstructive sleep apnea with and without oropharyngeal dysphagia. This study prospectively evaluated 22 patients with obstructive sleep apnea without spontaneous complaints of dysphagia, using a questionnaire, fiberoptic endoscopic evaluation of swallowing, and pharyngoesophageal manometry, including measurement of the upper and lower esophageal sphincter pressures and mean pharyngeal pressures at three levels during swallowing. The dysphagia group consisted of 17 patients (77.3%) in whom swallowing abnormalities were detected on fiberoptic endoscopic evaluation of swallowing (n=15; 68.2%) and/or in the questionnaire (n=7; 31.8%). The five remaining cases comprised a control group without oropharyngeal dysphagia. In all cases of abnormalities on fiberoptic endoscopic evaluation of swallowing, there was premature bolus leakage into the pharynx. There was no statistically significant difference between the groups regarding any of the pharyngoesophageal manometry measurements, age, or severity of obstructive sleep apnea. Pharyngoesophageal manometry detected no statistically significant difference between the groups with and without oropharyngeal dysphagia.

Ohki, Masafumi; Tayama, Niro

2013-06-01

Dementia with Lewy bodies (DLB) potentially causes dysphagia; however, the features and underlying mechanism causing dysphagia have still not been clarified. We are the first to report a case of dysphagia resulting from isoniazid therapy for tuberculosis in a DLB patient. A 74-year-old woman with DLB developed dysphagia during treatment for tuberculous pleurisy. Oral videoendoscopic and videofluorographic swallowing examinations showed oropharyngeal dysphagia. The increased administration of levodopa successfully ameliorated dysphagia. Therefore, dysphagia was ascribed to diminished levodopa efficacy due to interaction with isoniazid. Thus, DLB patients receiving anti-tuberculous therapy should be closely examined for potential changes in swallowing and Parkinsonism. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Signs of pharyngeal neurodegeneration have been detected in patients with obstructive sleep apnea (OSA). Along with this neurodegeneration, a decreased pharyngeal sensitivity to mechanical stimulation has been described. The decreased sensitivity may play a role in the pathophysiology of this disease. The aim of the study was to investigate the chemosensitivity of the pharyngeal mucosa in patients with OSA compared with controls. Healthy controls and patients with OSA (age: 30-60 years) were included. Testing of oropharyngeal chemosensitivity was performed with subjective intensity ratings of capsaicin (SIR, visual analogue scale 0-10), air puffs (presented with an olfactometer), and stimulation with CO2 at the posterior pharyngeal wall. A 2-point discrimination test at the soft palate, an intensity rating of capsaicin at the tongue, and a nasal lateralization test were performed. Twenty-six patients with OSA and 18 healthy controls were included. No differences were detected in the SIR of capsaicin at the tongue or in the nasal lateralization test. At the pharynx, a decreased sensitivity to capsaicin (OSA: 6.8 ± 2.3; healthy control: 8.6 ± 1.3), air puffs (OSA: 2.8 ± 1.9; healthy control: 4.2 ± 1.6), and stimulation with CO2 (OSA: 1.5 ± 1.7; healthy control: 2.8 ± 1.8) were demonstrated in patients with OSA (all P < 0.05). Two-point discrimination at the soft palate was reduced with statistical significance in the OSA group (OSA: 11.5 ± 5.4 mm; healthy control: 5.0 ± 2.4 mm). The results suggest reduced pharyngeal chemosensitivity in OSA patients in addition to the reduced mechanical pharyngeal sensitivity shown with 2-point discrimination. This demonstrates peripheral neurodegeneration in the context of this disease.

Postoperative dysphagia leads to aspiration pneumonia, prolonged hospital stay, and is associated with increased mortality. A simple and sensitive screening test to identify patients requiring objective dysphagia evaluation is presently lacking. In this study, we evaluated the efficacy of a novel targeted swallow screen evaluation. This was a prospective trial involving all adult patients who underwent elective cardiac surgery with cardiopulmonary bypass at our institution over an 8-week period. Within 24 hours of extubation and before the initiation of oral intake, all postsurgical patients were evaluated using the targeted swallow screen. A fiberoptic endoscopic evaluation of swallowing was requested for failed screenings. During the study, 50 postcardiac surgery patients were screened. Fifteen (30%) failed the targeted swallow screen, and ten of the fifteen (66%) failed the subsequent fiberoptic endoscopic evaluation of swallowing exam and were confirmed to have dysphagia. The screening test had 100 per cent sensitivity for detecting dysphagia in our patient population, and a specificity of 87.5 per cent. The overall incidence of dysphagia was 20 per cent. We have shown that a targeted swallow evaluation can efficiently screen patients during the postcardiac surgery period. Furthermore, we have shown that the true incidence of dysphagia after cardiac surgery is significantly higher than previously recognized in literature.

Some primary studies compare manual and mechanical pharyngeal closures after total laryngectomy. The purpose of this study was to evaluate the advantages of the mechanical suture in pharyngeal closure. The literature survey included research in MEDLINE, EMBASE, and LILACS. The intervention analyzed was stapler-assisted pharyngeal closure, whereas the control group was manual suture pharyngeal closure. The survey resulted in 319 studies. However, 4 studies were selected (417 patients). In the group of patients in whom the stapler was used, the incidence of pharyngocutaneous fistula was 8.7%, whereas in the other, it was 22.9%, with an absolute risk reduction of 15% (95% confidence interval [CI], 0.02-0.28; p = .02; I(2) = 66%). Regarding the surgical time, the average difference was 80 minutes in favor of the stapler group (95% CI, 23.16-136.58 minutes; p < .006). The difference for starting oral feeding was 8 days in favor of the mechanical suture (95% CI, 4.01-11.73 days; p < .001). Patients who underwent mechanical suture had a shorter hospitalization period. Copyright © 2013 Wiley Periodicals, Inc.

To investigate the influence of the local sensory abnormality in throat while the change of motility in the upper esophageal sphincter (UES) and lower esophageal sphincter (LES), as well as the change of esophageal body in pharyngeal paraesthesia. From January 2014 to January 2015 there were sixty-four patients who had pharyngeal susceptible syndrome (PSS) but without confirmed organic disease were enrolled as the PSS group, forty healthy volunteers as the control group. High resolution manometry (HRM) was utilized to distinguish esophageal motility patterns of PSS, including the muscular tension of LES and UES, the integrity, adaptability, amplitude, speed and duration of esophageal peristalsis at 10 swallows. The resting LES and UES pressures and the distal contractile integral (DCI) of esophagus in PSS group were lower than that in control group (P < 0.05). The esophageal peristalsis was decelerated and shortened in duration, and amplitude of contraction notably lower in PSS group compared with its counterpart (P < 0.05). The integrity of esophageal peristalsis was impaired in PSS with remarkable changes in motility patterns, involving ratio of major and minor interrupts, and synchronous contraction rate (P < 0.05). As for the time course from relaxation to the lowest pressure point of UES and time for restoration, no definite difference was noticed between the two groups (P > 0.05). The average peak pressure was similar in two groups (P > 0.05). Muscle tension around the UES has no obvious change when pharyngeal paraesthesia occurred, but the reduction of esophageal motor function, clearance ability, anti-reflux gastroesophageal junction, causing the abnormal reflux which hurt the pharyngeal surface mucosa maybe one of the most important reasons leading to pharyngeal paresthesia.

Evaluation of dysphagia typically starts with esophagogastroduodenoscopy (EGD); further testing is pursued if this is negative. When no mucosal, structural, or motor esophageal disorders are identified with persisting symptoms, functional dysphagia is considered. We evaluated outcomes in patients undergoing EGD for dysphagia, and estimated prevalence of functional dysphagia. The endoscopy database at single tertiary care center was interrogated to identify EGDs performed for an indication of 'dysphagia' over a 12-month period (2008-09). Electronic medical records were reviewed over the next 8 years to assess if an etiology was identified. Data were analyzed to assess the diagnostic yield of endoscopy and subsequent tests in the evaluation of dysphagia. Of 5486 EGDs, 822 (15.0%) were performed for dysphagia in 694 patients (58.4 ± 0.6 year, range: 18-95 year, 55.8% female). Of these, 529 (76.2%) had EGD findings that explained dysphagia; another 22 (3.2%) had findings on histopathology. Of the remainder 143 patients (20.6%) with normal index EGD, 38 (26.6%) patients underwent barium esophagram with 15 (39.5%) having abnormal studies. 19 patients (13.3%) underwent esophageal high resolution manometry with 12 (63.2%) being abnormal, and 7 had a mechanism for dysphagia on alternate testing. A repeat EGD was abnormal in 6 patients, while 45 patients were lost to follow-up. 42 patients had complete resolution of symptoms despite normal endoscopy, of which 30 were treated empirically with a proton pump inhibitor (PPI). Only 16 patients had no findings on evaluation, and had continued dysphagia symptoms, representing true functional dysphagia in 2.3% of all dysphagia patients and 11.2% of patients with normal EGD. Endoscopy remains the test with the highest yield (over 75%) for a diagnosis in patients presenting with dysphagia; secondary tests are useful when endoscopy does not provide a diagnosis. Benign strictures and GERD-related etiologies are leading causes; PPI

To elucidate independent risk factors for dysphagia after prolonged orotracheal intubation. The participants were 148 consecutive patients who underwent clinical bedside swallowing assessments from September 2009 to September 2011. All patients had received prolonged orotracheal intubations and were admitted to one of several intensive care units of a large Brazilian school hospital. The correlations between the conducted water swallow test results and dysphagia risk levels were analyzed for statistical significance. Of the 148 patients included in the study, 91 were male and 57 were female (mean age, 53.64 years). The univariate analysis results indicated that specific variables, including extraoral loss, multiple swallows, cervical auscultation, vocal quality, cough, choking, and other signs, were possible significant high-risk indicators of dysphagia onset. The multivariate analysis results indicated that cervical auscultation and coughing were independent predictive variables for high dysphagia risk. Patients displaying extraoral loss, multiple swallows, cervical auscultation, vocal quality, cough, choking and other signs should benefit from early swallowing evaluations. Additionally, early post-extubation dysfunction recognition is paramount in reducing the morbidity rate in this high-risk population.

Dysphagia is a fascinating symptom. It is ostensibly simple when defined by trouble swallowing, yet its subtleties in deciphering and its variations in pathophysiology almost mandate a thorough knowledge of medicine itself. With patience and careful questioning, a multitude of various disorders may be suggested before an objective test is performed. Indeed, the ability to diligently and comprehensively explore the symptom of dysphagia is not only rewarding but also a real test for a physician who prides himself or herself on good history taking.

2010-02-08

The non-motor symptoms of Parkinson's disease are a frequent and often under-diagnosed disorder. Two of the most significant non-motor symptoms are perhaps dysphagia and sialorrhea (which are relatively common in advanced stages of the disease) owing to their important functional repercussions and to the associated comorbidity. In recent years, different evaluation scales have been developed for clinical use and in screening the aforementioned symptoms. Of the different therapeutic options available, botulinum toxin represents the preferred treatment for sialorrhea. In contrast, speech therapy and an optimisation of the antiparkinsonian therapy are generally useful measures to treat dysphagia, percutaneous endoscopic gastrostomy being reserved for patients suffering from Parkinson who have severe dysphagia.

Classic infantile Pompe disease is an inherited generalized glycogen storage disorder caused by deficiency of lysosomal acid α-glucosidase. If left untreated, patients die before one year of age. Although enzyme-replacement therapy (ERT) has significantly prolonged lifespan, it has also revealed new aspects of the disease. For up to 11 years, we investigated the frequency and consequences of facial-muscle weakness, speech disorders and dysphagia in long-term survivors. Sequential photographs were used to determine the timing and severity of facial-muscle weakness. Using standardized articulation tests and fibreoptic endoscopic evaluation of swallowing, we investigated speech and swallowing function in a subset of patients. This study included 11 patients with classic infantile Pompe disease. Median age at the start of ERT was 2.4 months (range 0.1-8.3 months), and median age at the end of the study was 4.3 years (range 7.7 months -12.2 years). All patients developed facial-muscle weakness before the age of 15 months. Speech was studied in four patients. Articulation was disordered, with hypernasal resonance and reduced speech intelligibility in all four. Swallowing function was studied in six patients, the most important findings being ineffective swallowing with residues of food (5/6), penetration or aspiration (3/6), and reduced pharyngeal and/or laryngeal sensibility (2/6). We conclude that facial-muscle weakness, speech disorders and dysphagia are common in long-term survivors receiving ERT for classic infantile Pompe disease. To improve speech and reduce the risk for aspiration, early treatment by a speech therapist and regular swallowing assessments are recommended.

Summary Introduction: Hyperplasia of the pharyngeal tonsil is one of the main causes of mouth breathing, and accurate diagnosis of this alteration is important for proper therapeutic planning. Therefore, studies have been conducted in order to provide information regarding the procedures that can be used for the diagnosis of pharyngeal obstruction. Objective: To verify the correlation between nasopharyngoscopy and cephalometric examinations in the diagnosis of pharyngeal tonsil hyperplasia. Method: This was a cross-sectional, clinical, experimental, and quantitative study. Fifty-five children took part in this study, 30 girls and 25 boys, aged between 7 and 11 years. The children underwent nasofibropharyngoscopic and cephalometric evaluation to determine the grade of nasopharyngeal obstruction. The Spearman's rank correlation coefficient at the 5% significance level was used to verify the correlation between these exams. Results: In the nasopharyngoscopy evaluation, most children showed grade 2 and 3 hyperplasia of the pharyngeal tonsil, which was followed by grade 1. In the cephalometry assessment, most children showed grade 1 hyperplasia of the pharyngeal tonsil, which was followed by grade 2. A statistically significant regular positive correlation was observed between the exams. Conclusion: It was concluded that the evaluation of the pharyngeal tonsil hyperplasia could be carried out by fiber optic nasopharyngoscopy and cephalometry, as these examinations were regularly correlated. However, it was found that cephalometry tended to underestimate the size of the pharyngeal tonsil relative to nasopharyngoscopy. PMID:25991937

To investigate the effects of VitalStim therapy coupled with conventional swallowing training on recovery of post-stroke dysphagia, a total of 120 patients with post-stroke dysphagia were randomly and evenly divided into three groups: conventional swallowing therapy group, VitalStim therapy group, and VitalStim therapy plus conventional swallowing therapy group. Prior to and after the treatment, signals of surface electromyography (sEMG) of swallowing muscles were detected, swallowing function was evaluated by using the Standardized Swallowing Assessment (SSA) and Videofluoroscopic Swallowing Study (VFSS) tests, and swallowing-related quality of life (SWAL-QOL) was evaluated using the SWAL-QOL questionnaire. There were significant differences in sEMG value, SSA, VFSS, and SWAL-QOL scores in each group between prior to and after treatment. After 4-week treatment, sEMG value, SSA, VFSS and SWAL-QOL scores were significantly greater in the VitalStim therapy plus conventional swallowing training group than in the conventional swallowing training group and VitalStim therapy group, but no significant difference existed between conventional swallowing therapy group and VitalStim therapy group. It was concluded that VitalStim therapy coupled with conventional swallowing training was conducive to recovery of post-stroke dysphagia.

The incidence of functional dysphagia was 7 out of 22 (32%); it was self-limiting in 5 out of 7 (71%) of the cases and associated with the incidence of vocal cord palsy (p = 0.0006). Functional dysphagia after transhiatal oesophagectomy occurs frequently, but is self-limiting in most patients. Injury to branches of the recurrent laryngeal nerve is a likely cause.

Diagnosis and treatment of streptococcal pharyngitis.

PubMed

Choby, Beth A

2009-03-01

Common signs and symptoms of streptococcal pharyngitis include sore throat, temperature greater than 100.4 degrees F (38 degrees C), tonsillar exudates, and cervical adenopathy. Cough, coryza, and diarrhea are more common with viral pharyngitis. Available diagnostic tests include throat culture and rapid antigen detection testing. Throat culture is considered the diagnostic standard, although the sensitivity and specificity of rapid antigen detection testing have improved significantly. The modified Centor score can be used to help physicians decide which patients need no testing, throat culture/rapid antigen detection testing, or empiric antibiotic therapy. Penicillin (10 days of oral therapy or one injection of intramuscular benzathine penicillin) is the treatment of choice because of cost, narrow spectrum of activity, and effectiveness. Amoxicillin is equally effective and more palatable. Erythromycin and first-generation cephalosporins are options in patients with penicillin allergy. Increased group A beta-hemolytic streptococcus (GABHS) treatment failure with penicillin has been reported. Although current guidelines recommend first-generation cephalosporins for persons with penicillin allergy, some advocate the use of cephalosporins in all nonallergic patients because of better GABHS eradication and effectiveness against chronic GABHS carriage. Chronic GABHS colonization is common despite appropriate use of antibiotic therapy. Chronic carriers are at low risk of transmitting disease or developing invasive GABHS infections, and there is generally no need to treat carriers. Whether tonsillectomy or adenoidectomy decreases the incidence of GABHS pharyngitis is poorly understood. At this time, the benefits are too small to outweigh the associated costs and surgical risks.

Dysphagia is a common, serious health problem with a wide variety of etiologies and manifestations. This review gives a general overview of diagnostic and therapeutic options for oropharyngeal as well as esophageal swallowing disorders respecting the considerable progress made over recent years. Diagnosis can be challenging and requires expertise in interpretation of symptoms and patient history. Endoscopy, barium radiography and manometry are still the diagnostic mainstays. Classification of esophageal motor-disorders has been revolutionized with the introduction of high-resolution esophageal pressure topography and a new standardized classification algorithm. Automated integrated impedance manometry is a promising upcoming tool for objective evaluation of oropharyngeal dysphagia, in non-obstructive esophageal dysphagia and prediction of post fundoplication dysphagia risk. Impedance planimetry provides new diagnostic information on esophageal and LES-distensibility and allows controlled therapeutic dilatation without the need for radiation. Peroral endoscopic myotomy is a promising therapeutic approach for achalasia and spastic motility disorders.

Dysphagia is relatively common in patients with Parkinson disease (PD) and can have a negative impact on their quality of life; therefore, it is imperative that its prevalence in PD patients is studied. The aim of this study was to explore the prevalence and clinical correlation of dysphagia in Chinese PD patients. We recruited 116 Chinese PD patients. A videofluoroscopic study of swallowing (VFSS) was used to identify dysphagia. Assessments, including water drinking test, relative motor symptoms, non-motor symptoms (NMS) and quality of life, were performed to analyze the risks of dysphagia. The prevalence of dysphagia was 87.1%. The comparison of demographic and clinical features between patients with and without dysphagia included sex, education level, disease course, Mini-mental State Examination (MMSE), Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), Question 6, 7 of the Unified Parkinson Disease Rating Scale (UPDRS Part II), Hoehn-Yahr stage (H&Y), water drinking test, 39-item Parkinson Disease Questionnaire (PDQ-39) and Non-Motor Symptoms Quest (NMSQ). We found significant correlations between dysphagia and age. Using age, disease course, and H&Y stage as the independent variable in our regression analysis for assessing the risk factors of dysphagia in PD patients, age and H&Y stage displayed a strong correlation as the risk factors. The risk of dysphagia in elderly PD patients is 1.078 times greater than that of younger PD patients. Also, the risk of dysphagia in PD patients of a greater H&Y staging is 3.260 times greater than that of lower staging PD patients. Our results suggest that dysphagia is common in Chinese PD patients. Older patients or those in higher H&Y stages are more likely to experience dysphagia. There is no correlation between dysphagia and PD duration.

Summary Introduction: Stroke is considered one of the most frequent neurological causes of oropharyngeal dysphagia. Aim: To determine the effect of cryostimulation on oropharyngeal sensitivity and, subsequently, on the swallowing reaction and premature escape of food in patients with neurogenic dysphagia after stroke. Methods: Clinical and experimental study. The study enrolled 7 adult subjects, 6 men and 1 woman ranging from 28 to 64 years of age, with a diagnosis of stroke and current oropharyngeal dysphagia without any other underlying disease. The selected subjects underwent speech-language pathology evaluation and videofluoroscopic assessment of the dysphagia. The subjects were then treated with cryostimulation consisting of 10 applications to each structure (anterior faucial pillar, posterior oropharyngeal wall, soft palate, and back tongue) 3 times a day (for a total of 30 daily applications per structure) for 4 consecutive days. The patients were then re-evaluated based on the same criteria. The pre- and post-cryostimulation results of the clinical and videofluoroscopic evaluations were analyzed descriptively and statistically using Student's t-test and Fisher's exact test. Results: Cryostimulation had beneficial effects on oropharyngeal sensitivity in 6 of the 7 subjects. There was also a significant improvement in swallowing and in the premature escape in six subjects. Conclusion: Cryostimulation increased sensitivity and subsequently improved the swallowing reaction and premature escape of food in patients with neurogenic dysphagia after stroke. These effects were evident by both speech-language pathology and videofluoroscopic evaluation. PMID:25991991

Background Despite the wide implementation of dysphagia therapies, it is unclear whether these therapies are successfully communicated beyond the inpatient setting. Objective To examine the rate of dysphagia recommendation omissions in hospital discharge summaries for high-risk sub-acute care (i.e., skilled nursing facility, rehabilitation, long-term care) populations. Design Retrospective cohort study Subjects All stroke and hip fracture patients billed for inpatient dysphagia evaluations by speech-language pathologists (SLPs) and discharged to sub-acute care in 2003-2005 from a single large academic medical center (N=187). Measurements Dysphagia recommendations from final SLP hospital notes and from hospital (physician) discharge summaries were abstracted, coded, and compared for each patient. Recommendation categories included: dietary (food and liquid), postural/compensatory techniques (e.g., chin-tuck), rehabilitation (e.g., exercise), meal pacing (e.g., small bites), medication delivery (e.g., crush pills), and provider/supervision (e.g., 1-to-1 assist). Results 45% of discharge summaries omitted all SLP dysphagia recommendations. 47%(88/186) of patients with SLP dietary recommendations, 82%(93/114) with postural, 100%(16/16) with rehabilitation, 90%(69/77) with meal pacing, 95%(21/22) with medication, and 79%(96/122) with provider/supervision recommendations had these recommendations completely omitted from their discharge summaries. Conclusions Discharge summaries omitted all categories of SLP recommendations at notably high rates. Improved post-hospital communication strategies are needed for discharges to sub-acute care.

Objective to evaluate the risk of dysphagia and its relationship with the stage of Alzheimer's Disease, as well as the relationship between the risk of dysphagia and nutritional status and caloric intake in elderly people with Alzheimer's disease. Methods the sample consisted of 30 subjects of both genders with probable Alzheimer's disease. The stage of the disease, nutritional status, energy intake, and risk of dysphagia were assessed. Results it was found that increased risk of dysphagia is associated with the advance in the stages of Alzheimer's disease and that even patients in the early stages of disease have a slight risk of developing dysphagia. No association was found between nutritional status and the risk of dysphagia. High levels of inadequate intake of micronutrients were also verified in the patients. Conclusion an association between dysphagia and the development of Alzheimer's disease was found. The results indicate the need to monitor the presence of dysphagia and the micronutrient intake in patients with Alzheimer's disease. PMID:26107841

Dysphagia is a common symptom in clinical practice. Due to the broad spectrum of underlying diseases many disciplines are involved in the therapy and diagnosis of dysphagia, where radiology plays a central role. The radiologist is confronted with different diagnostic problems and has to choose the most appropriate type of investigation. In many cases no organic disorder can be demonstrated by clinical examination, endoscopy or conventional radiological techniques. In this setting cineradiography is an outstanding tool for finding functional or structural changes in the swallowing chain. This study underlines the efficiency of cineradiography in the diagnosis of dysphagia.

Oropharyngeal and esophageal dysphagia are a frequent, but seldom diagnosed symptom of Parkinson's disease (PD). More than 80 % of patients with PD develop dysphagia during the course of their disease leading to a reduced quality of life, complicated medication intake, malnutrition and aspiration pneumonia, which is a major cause of death in PD. The underlying pathophysiology is poorly understood. Impaired dopaminergic and non-dopaminergic mechanisms of the cortical swallowing network as well as peripheral neuromuscular involvement have been suggested to contribute to its multifactorial genesis. Diagnostic screening methods include PD-specific questionnaires and a modified water test. Fiber optic endoscopic evaluation of swallowing (FEES) and videofluoroscopic swallowing study (VFSS), which complement each other, are the gold standard for evaluation of PD-related dysphagia. For evaluation of esophageal dysphagia, the high-resolution manometry (HRM) may be a helpful tool. In addition to dysphagia-specific treatment by speech and language therapists (SLTs), optimized dopaminergic medication is a meaningful therapeutic option. A promising novel method is intensive training of expiratory muscle strength (EMST). Deep brain stimulation does not seem to have a clinically relevant effect on swallowing function in PD. © Georg Thieme Verlag KG Stuttgart · New York.

Dysphagia is a debilitating symptom in patients with inoperable esophageal cancer contributing to poor quality of life and worsening nutritional status. The 2 most commonly used palliative modalities for dysphagia are radiation therapy (RT) and esophageal stent placement. However, RT is limited by adverse events (AEs) and total dose, and stent placement has a high rate of AEs including reflux, migration, and chest pain. A relatively new modality of liquid nitrogen endoscopic spray cryotherapy has been described as salvage when other options have been exhausted and when patients are no longer receiving systemic therapy. We evaluated the safety and efficacy of cryotherapy as the primary modality for relieving dysphagia in inoperable esophageal cancer including patients receiving systemic cancer therapy. This is a retrospective multicenter consecutive case series of 49 inoperable esophageal cancer patients undergoing palliative endoscopic cryotherapy at 4 specialized cancer centers from May 2014 to May 2016. The primary outcomes were change in dysphagia scores between pre- and post-cryotherapy and AE. Dysphagia was measured using a 4-point Likert scale: 0, no dysphagia; 1, dysphagia to solids; 2, dysphagia to semi-solids; 3, dysphagia to liquids; 4, dysphagia to saliva. There were 39 males and 10 females with a mean age of 58 years who underwent a total of 120 cryotherapy treatments. The mean dysphagia score improved significantly from 2.4 pre-cryotherapy to 1.7 post-cryotherapy (improvement of 0.7 points; p<0.001). Minor AE were seen in 6/120 (5.0%) cryotherapy treatments (1 intra-procedural and 5 post-procedural). In addition, one patient developed a severe intra-procedural AE of dilation-related perforation whereas another patient developed a benign stricture requiring dilation. This preliminary retrospective study suggests that liquid nitrogen spray cryotherapy may be safe and effective for dysphagia palliation in inoperable esophageal cancer. Large prospective

Study Objectives Pharyngeal muscle dilators are important in obstructive sleep apnea pathogenesis because the failure of protective reflexes involving these muscles yields pharyngeal collapse. Conflicting results exist in the literature regarding the responsiveness of these muscles during stable non-rapid eye movement sleep. However, variations in posture in previous studies may have influenced these findings. We hypothesized that tongue protruder muscles are maximally responsive to negative pressure pulses during supine sleep, when posterior tongue displacement yields pharyngeal occlusion. Design We studied all subjects in the supine and lateral postures during wakefulness and stable non-rapid eye movement sleep by measuring genioglossus and tensor palatini electromyograms during basal breathing and following negative pressure pulses. Setting Upper-airway physiology laboratory of Sleep Medicine Division, Brigham and Women’s Hospital. Subjects/Participants 17 normal subjects. Measurements and Results We observed an increase in genioglossal responsiveness to negative pressure pulses in sleep as compared to wakefulness in supine subjects (3.9 percentage of maximum [%max] ± 1.1 vs 4.4 %max ± 1.0) but a decrease in the lateral decubitus position (4.1 %max ± 1.0 vs 1.5 %max ± 0.4), the interaction effect being significant. Despite this augmented reflex, collapsibility, as measured during negative pressure pulses, increased more while subjects were in the supine position as compared with the lateral decubitus position. While the interaction between wake-sleep state and position was also significant for the tensor palatini, the effect was weaker than for genioglossus, although, for tensor palatini, baseline activity was markedly reduced during non-rapid eye movement sleep as compared with wakefulness. Conclusions We conclude that body posture does have an important impact on genioglossal responsiveness to negative pressure pulses during non-rapid eye movement sleep

Dysphonia and dysphagia are common complications of anterior cervical discectomy (ACD). We sought to determine the relationship between dysphagia and in-hospital mortality, complications, speech therapy/dysphagia training, length of hospitalization, and costs associated with ACD. Discharge data from the Nationwide Inpatient Sample for 1,649,871 patients who underwent ACD of fewer than four vertebrae for benign acquired disease between 2001 and 2010 were analyzed using cross-tabulations and multivariate regression modeling. Dysphagia was reported in 32,922 cases (2.0 %). Speech therapy/dysphagia training was reported in less than 0.1 % of all cases and in only 0.2 % of patients with dysphagia. Dysphagia was significantly associated with age ≥65 years (OR = 1.5 [95 % CI 1.4-1.7], P < 0.001), advanced comorbidity (OR = 2.3 [2.0-2.6], P < 0.001), revision surgery (OR = 2.7 [2.3-3.1], P < 0.001), disc prosthesis placement (OR = 1.5 [1.0-2.0], P = 0.029), and vocal cord paralysis (OR = 11.6 [8.3-16.1], P < 0.001). Dysphagia was a significant predictor of aspiration pneumonia (OR = 8.6 [6.7-10.9], P < 0.001), tracheostomy (OR = 2.3 [1.6-3.3], P < 0.001), gastrostomy (OR = 30.9 [25.3-37.8], P < 0.001), and speech therapy/dysphagia training (OR = 32.0 [15.4-66.4], P < 0.001). Aspiration pneumonia was significantly associated with in-hospital mortality (OR = 15.9 [11.0-23.1], P < 0.001). Dysphagia, vocal cord paralysis, and aspiration pneumonia were significant predictors of increased length of hospitalization and hospital-related costs, with aspiration pneumonia having the single largest impact on length of hospitalization and costs. Dysphagia is significantly associated with increased morbidity, length of hospitalization, and hospital-related costs in ACD patients. Despite the known risk of dysphagia in ACD patients and an established role for the speech-language pathologist in dysphagia management, speech-language pathology

Dysphagia is listed as a 'rare' side effect following clozapine treatment. In this case report, we describe how significant clozapine-induced dysphagia has led to significant reduction of nutritional intake with subsequent substantial weight loss. An 18-year-old single man with an established diagnosis of treatment-resistant paranoid schizophrenia recovered well on a therapeutic dose of clozapine. However, he was noted to lose weight significantly (up to 20% of his original weight) as the dose was uptitrated. This was brought about by development of dysphagia, likely to be due to clozapine. Addition of nutritional supplementary liquids and initiation of a modified behavioural dietary/swallowing programme, while repeatedly mastering the Mendelsohn manoeuvre technique, alleviated the swallowing difficulties and restored his weight. 2016 BMJ Publishing Group Ltd.

Background Inappropriate use of antibiotic treatment for pharyngitis by community pharmacists is prevalent in developing countries. Little is known about how the pharmacists identify patients with bacterial pharyngitis. Objective To ascertain the appropriateness of diagnosis of streptococcal pharyngitis among Thai community pharmacists according to the Centor criteria and to identify factors related to antibiotic dispensing. Setting 1040 Thai community pharmacists. Method A cross-sectional survey of community pharmacists was conducted in November 2012 to March 2013. The self-administered questionnaires were mailed to 57 % of community pharmacists in the south of Thailand (n = 1040). The survey included questions on diagnosis of streptococcal pharyngitis, knowledge on pharyngitis, and attitudes and control beliefs regarding antibiotic dispensing. Main outcome measure The appropriateness of diagnosis of streptococcal pharyngitis according to the original and modified Centor criteria and determinants of antibiotic dispensing including demographic characteristics of pharmacists, knowledge on pharyngitis, and attitudes and control beliefs on antibiotic dispensing. Results Approximately 68 % completed the questionnaires (n = 703). Compared to the pharmacists who reported not dispensing antibiotics in the hypothetical case with common cold, those reported dispensing antibiotics were more likely to consider the following conditions-presence of cough, mild sore throat and patients with age >60 years as cues for diagnosis of streptococcal pharyngitis (p < 0.05). The use of fewer scores of the clinical prediction rules for diagnosis was observed in antibiotic dispensers, compared to who did not do so (p < 0.005). Antibiotic dispensing was positively associated with period of dispensing experience (>5 years) [odds ratio (OR) 1.52; 95 % confidence interval (CI) 1.03-2.23], belief that antibiotics could shorten duration of pharyngitis (OR 1.48; 95 % CI 1

Bedside evaluation of dysphagia may be challenging in left middle cerebral artery (MCA) stroke due to frequently existing aphasia. Here we analyse the predictive value of common bedside screening tests and of two items of cortical dysfunction, aphasia and buccofacial apraxia (BFA), for the detection of dysphagia. We prospectively examined 67 consecutive patients with clinical and imaging evidence of acute (<72 h) left MCA stroke. Dysphonia, dysarthria, abnormal volitional cough and abnormal gag reflex were assessed followed by a standardized 50-ml water-swallowing test determining the symptoms cough and voice change after swallow. Aphasia and BFA were assessed according to defined criteria. Fibre-optic endoscopic evaluation of swallowing (FEES) was performed for validation of dysphagia. 41 (61%) patients had FEES-proven dysphagia. Abnormal gag reflex, abnormal volitional cough, cough after swallow, aphasia and BFA were significantly more frequent in dysphagic as compared to non-dysphagic patients, while dysphonia, dysarthria and voice change after swallow were not. Aphasia and BFA had the highest sensitivity (97 and 78%, respectively) and high negative predictive values (89 and 68%, respectively) for dysphagia. Multivariate regression analysis did not identify an independent predictor of dysphagia. In left MCA stroke, the sensitivity and specificity of common bedside dysphagia screening methods are low. In contrast, aphasia and BFA have a high sensitivity and high negative predictive power, presumably due to the neuro-anatomical overlap between cortical regions involved in swallowing, speech production, imitation and voluntary movement control. © 2014 S.

Oropharyngeal dysphagia (OD) is very prevalent among poststroke patients, causing severe complications but lacking specific neurorehabilitation treatment. This review covers advances in the pathophysiology, diagnosis, and physiologically based neurorehabilitation strategies for poststroke OD. The pathophysiology of oropharyngeal biomechanics can be assessed by videofluoroscopy, as delayed laryngeal vestibule closure is closely associated with aspiration. Stroke may affect afferent or efferent neuronal circuits participating in deglutition. The integrity of oropharyngeal-cortical afferent pathways can be assessed by electroencephalography through sensory-evoked potentials by pharyngeal electrical stimulation, while corticopharyngeal efferent pathways can be characterized by electromyography through motor-evoked potentials by transcranial magnetic stimulation. Dysfunction in both cortico-mediated evoked responses is associated with delayed swallow response and aspiration. Studies have reported hemispherical asymmetry on motor control of swallowing and the relevance of impaired oropharyngeal sensitivity on aspiration. Advances in treatment include improvements in compensatory strategies but are mainly focused on (1) peripheral stimulation strategies and (2) central, noninvasive stimulation strategies with evidence of their clinical benefits. Characterization of poststroke OD is evolving from the assessment of impaired biomechanics to the sensorimotor integration processes involved in deglutition. Treatment is also changing from compensatory strategies to promoting brain plasticity, both to recover swallow function and to improve brain-related swallowing dysfunction. © 2016 New York Academy of Sciences.

Diagnosis of Swallowing Disorders: How We Interpret Pharyngeal Manometry.

Cock, Charles; Omari, Taher

We provide an overview of the clinical application of novel pharyngeal high-resolution impedance manometry (HRIM) with pressure flow analysis (PFA) in our hands with example cases. In our Centre, we base our interpretation of HRIM recordings upon a qualitative assessment of pressure-impedance waveforms during individual swallows, as well as a quantitative assessment of averaged PFA swallow function variables. We provide a description of two global swallowing efficacy measures, the swallow risk index (SRI), reflecting global swallowing dysfunction (higher SRI = greater aspiration risk) and the post-swallow impedance ratio (PSIR) detecting significant post-swallow bolus residue. We describe a further eight swallow function variables specific to the hypopharynx and upper esophageal sphincter (UES), assessing hypo-pharyngeal distension pressure, contractility, bolus presence and flow timing, and UES basal tone, relaxation, opening and contractility. Pharyngeal HRIM has now come of age, being applicable for routine clinical practice to assess the biomechanics of oropharyngeal swallowing dysfunction. In the future, it may guide treatment strategies and allow more objective longitudinal follow-up on clinical outcomes.

OBJECTIVES: To elucidate independent risk factors for dysphagia after prolonged orotracheal intubation. METHODS: The participants were 148 consecutive patients who underwent clinical bedside swallowing assessments from September 2009 to September 2011. All patients had received prolonged orotracheal intubations and were admitted to one of several intensive care units of a large Brazilian school hospital. The correlations between the conducted water swallow test results and dysphagia risk levels were analyzed for statistical significance. RESULTS: Of the 148 patients included in the study, 91 were male and 57 were female (mean age, 53.64 years). The univariate analysis results indicated that specific variables, including extraoral loss, multiple swallows, cervical auscultation, vocal quality, cough, choking, and other signs, were possible significant high-risk indicators of dysphagia onset. The multivariate analysis results indicated that cervical auscultation and coughing were independent predictive variables for high dysphagia risk. CONCLUSIONS: Patients displaying extraoral loss, multiple swallows, cervical auscultation, vocal quality, cough, choking and other signs should benefit from early swallowing evaluations. Additionally, early post-extubation dysfunction recognition is paramount in reducing the morbidity rate in this high-risk population. PMID:24473554

Role of videofluoroscopy in evaluation of neurologic dysphagia

2007-01-01

Summary For many years, videofluoroscopy was considered the gold standard for studies on swallowing disorders, and only recently has its role been challenged, due primarily to the widespread use of videoendoscopy in the evaluation of dysphagia. Albeit, videofluoroscopy still maintains its key role in this area and, in particular, in studies on dysphagia of neurological origin, on account not only of the possibility, with this procedure, to achieve complete and dynamic evaluation of all phases of deglutition, but also the high sensitivity and specificity in revealing the presence of inhalation. Aim of the present investigation was to analyse the technical procedure of videofluoroscopy and the principal indications in the study of dysphagia of neurological origin, in the attempt to reveal the advantages and disadvantages occurring in this examination, also with respect to other methods adopted in the evaluation of dyphagia. In conclusion, at present, no instrumental examination can be defined as ideal for the study of swallowing, but it can be seen that, with each of these procedures, the information forthcoming is actually complementary, thus achieving the aim to proceed as correctly and rapidly as possible, with the management of patients with dysphagia.

A number of reports have investigated the relationship between laryngeal papilloma and human papilloma virus (HPV) infection. On the other hand, it is unclear whether the HPV infection is involved in the occurrence of pharyngeal papilloma. We hypothesized that HPV infection was involved in the occurrence of pharyngeal papilloma similarly to laryngeal papilloma. To verify this hypothesis, we investigated the presence of HPV infection. Furthermore, clinical manifestations of pharyngeal papilloma, which had rarely been reported, were discussed. A male-to-female ratio, solitary or multiple occurrences, and koilocytosis were examined in cases with pharyngeal papilloma. HPV DNA was examined with unfixed surgically resected specimens of pharyngeal papilloma. A screening test by the liquid-phase hybridization method was carried out for the HPV high-risk group (16, 18, 31, 33, 35, 39, 45, 51, 56, 58, 59, and 68) and HPV low-risk group (6, 11, 42, 43, 44). As a control, 15 cases with laryngeal papilloma for which the same screening test was carried out were employed. Pharyngeal papilloma occurred as a solitary lesion more often, whereas laryngeal papilloma occurred as multiple tumors more frequently. The HPV infection rate was 0% in pharyngeal papilloma cases, which was in stark contrast with 66.7% in the HPV low-risk group in laryngeal papilloma cases. Pharyngeal papilloma occurred as a solitary lesion in females more frequently. Contrary to our hypothesis, the involvement of HPV infection was unlikely in the occurrence of pharyngeal papilloma.

Although previous studies demonstrated that patients with obstructive sleep apnea syndrome (OSAS) may present subclinical manifestations of dysphagia, in not one were different textures and volumes systematically studied. The aim of this study was to analyze the signs and symptoms of oropharyngeal dysphagia using fiberoptic endoscopic evaluation of swallowing (FEES) with boluses of different textures and volumes in a large cohort of patients with OSAS. A total of 72 OSAS patients without symptoms of dysphagia were enrolled. The cohort was divided in two groups: 30 patients with moderate OSAS and 42 patients with severe OSAS. Each patient underwent a FEES examination using 5, 10 and 20 ml of liquids and semisolids, and solids. Spillage, penetration, aspiration, retention, and piecemeal deglutition were considered. The penetration-aspiration scale (PAS), pooling score (PS), and dysphagia outcome and severity scale (DOSS) were used for quantitative analysis. Each patient completed the SWAL-QOL questionnaire. Forty-six patients (64 %) presented spillage, 20 (28 %) piecemeal deglutition, 26 (36 %) penetration, and 30 (44 %) retention. No differences were found in the PAS, PS, and DOSS scores between patients with moderate and severe OSAS. Patients with severe OSAS scored higher General Burden and Food selection subscales of the SWAL-QOL. Depending on the DOSS score, the cohort of patients was divided into those with and those without signs of dysphagia. Patients with signs of dysphagia scored lower in the General Burden and Symptoms subscales of the SWAL-QOL. OSAS patients show signs of swallowing impairment in about half of the population; clinicians involved in the management of these patients should include questions on swallowing when taking the medical history.

Group A Streptococcus (GAS) pharyngitis is currently the only commonly occurring form of acute pharyngitis for which antibiotic therapy is definitely indicated. Polish guidelines advocate the use of modified Centor score (MCS) to assess the probability of GAS pharyngitis. They advise performing throat culture or rapid antigen detection test (RADT) in children with score 2-3 in MCS and treating with antibiotic only those in whom GAS was detected. Negative RADT results should be confirmed by culture. In children with score 4, the guidelines allow to introduce empiric antibiotic therapy. Phenoxymethyl penicillin is recommended as a drug of choice to treat GAS pharyngitis. The aim of our study was to evaluate the accuracy of strategy recommended by Polish guidelines in identifying those children with acute pharyngitis who require antibiotic treatment. Hence, diagnostic values of score 4 in MCS and RADT were assessed using throat culture as a reference standard. Phenoxymethyl penicillin efficacy in GAS eradication and prevention of post-streptococcal complications were estimated as well. Ninety children between 2 and 15 years of age with acute pharyngitis symptoms suggesting GAS etiology (MCS ≥ 2), participated in our study. At the initial visit MCS was evaluated and two throat swabs were collected to perform RADT and culture. In children with GAS pharyngitis treated with penicillin, microbiological cure was assessed by performing two control throat cultures. Next, children were under observation for 3 months. Positive predictive value of score 4 in MCS turned out to be 48.05% (95% CI: 36.5-59.7%). RADT sensitivity, specificity and diagnostic accuracy proved to be 100%, 96%, and 98%, respectively. GAS eradication rate in children treated with penicillin turned out to be 92.5%. No post-streptococcal sequelae occurred in any child in 3-month observation. Empiric antibiotic therapy in children with score 4 in MCS will result in significant overtreatment of those with

Videofluoroscopic imaging of swallowing known as the Modified Barium Study (MBS) is the standard of care for assessing swallowing difficulty. While the clinical purpose of this radiographic imaging is to primarily assess aspiration risk, valuable biomechanical data is embedded in these studies. Computational analysis of swallowing mechanics (CASM) is an established research methodology for assessing multiple interactions of swallowing mechanics based on coordinates mapping muscle function including hyolaryngeal movement, pharyngeal shortening, tongue base retraction, and extension of the head and neck, however coordinates characterizing pharyngeal constriction is undeveloped. The aim of this study was to establish a method for locating the superior and middle pharyngeal constrictors using hard landmarks as guides on MBS videofluoroscopic imaging, and to test the reliability of this new method. Twenty de-identified, normal, MBS videos were randomly selected from a database. Two raters annotated landmarks for the superior and middle pharyngeal constrictors frame-by-frame using a semi-automated MATLAB tracker tool at two time points. Intraclass correlation coefficients were used to assess test-retest reliability between two raters with an ICC = 0.99 or greater for all coordinates for the retest measurement. MorphoJ integrated software was used to perform a discriminate function analysis to visualize how all 12 coordinates interact with each other in normal swallowing. The addition of the superior and middle pharyngeal constrictor coordinates to CASM allows for a robust analysis of the multiple components of swallowing mechanics interacting with a wide range of variables in both patient specific and cohort studies derived from common use imaging data.

Dysphagia is common in Parkinson’s disease (PD) and causes significant morbidity and mortality. PD dysphagia has usually been explained as dysfunction of central motor control, much like other motor symptoms that are characteristic of the disease. However, PD dysphagia does not correlate with severity of motor symptoms nor does it respond to motor therapies. It is known that PD patients have sensory deficits in the pharynx, and that impaired sensation may contribute to dysphagia. However, the underlying cause of the pharyngeal sensory deficits in PD is not known. We hypothesized that PD dysphagia with sensory deficits may be due to degeneration of the sensory nerve terminals in the upper aerodigestive tract (UAT). We have previously shown that Lewy-type synucleinopathy (LTS) is present in the main pharyngeal sensory nerves of PD patients, but not in controls. In this study, the sensory terminals in UAT mucosa were studied to discern the presence and distribution of LTS. Whole-mount specimens (tongue-pharynx-larynx-upper esophagus) were obtained from 10 deceased human subjects with clinically diagnosed and neuropathologically confirmed PD (five with dysphagia and five without) and four age-matched healthy controls. Samples were taken from six sites and immunostained for phosphorylated α-synuclein (PAS). The results showed the presence of PAS-immunoreactive (PAS-ir) axons in all the PD subjects and in none of the controls. Notably, PD patients with dysphagia had more PAS-ir axons in the regions that are critical for initiating the swallowing reflex. These findings suggest that Lewy pathology affects mucosal sensory axons in specific regions of the UAT and may be related to PD dysphagia. PMID:26041249

The Dysphagia Handicap Index (DHI) is a 25-item questionnaire assessing the physical, functional, and emotional aspects of dysphagia patients' quality of life (QoL). The study goal was to translate and validate the Hebrew-DHI. 148 patients undergoing fiberoptic endoscopic examination of swallowing (FEES) in two specialized dysphagia clinics between February and August 2017 filled the Hebrew-DHI and self-reported their dysphagia severity on a scale of 1-7. 21 patients refilled the DHI during a 2-week period following their first visit. FEES were scored for residue (1 point per consistency), penetration and aspiration (1 point for penetration, 2 points for aspiration, per consistency). 51 healthy volunteers also filled the DHI. Internal consistency and test-retest reproducibility were used for reliability testing. Validity was established by comparing DHI scores of dysphagia patients and healthy controls. Concurrent validity was established by correlating the DHI score with the FEES score. Internal consistency of the Hebrew-DHI was high (Cronbach's alpha = 0.96), as was the test-retest reproducibility (Spearman's correlation coefficient = 0.82, p < 0.001). The Hebrew-DHI's total score, and its three subscales (physical/functional/emotional) were significantly higher in dysphagia patients compared to those in healthy controls (median 38 pts, IQR 18-56 for dysphagia patients compared to 0, IQR 0-2 for healthy controls, p < 0.0001). A strong correlation was observed between the DHI score and the self-reported dysphagia severity measure (Spearman's correlation coefficient = 0.88, p < 0.0001). A moderate correlation was found between the DHI score and the FEES score (Pearson's correlation coefficient = 0.245, p = 0.003). The Hebrew-DHI is a reliable and valid questionnaire assessing dysphagia patients' QoL.

Our objective is to explore the effectiveness and feasibility of establishing a swallowing management clinic to implement out-of-hospital management for Parkinson disease (PD) patients with dysphagia. Two-hundred seventeen (217) voluntary PD patients with dysphagia in a PD outpatient clinic were divided into a control group with 100 people, and an experimental group with 117 people. The control group was given dysphagia rehabilitation guidance. The experimental group was presented with the standardized out-of-hospital management method as overall management and information and education materials. Rehabilitation efficiency and incidence rate of dysphagia, as well as relevant complications of both groups were compared after a 6-month intervention. Rehabilitation efficiency and the incidence rate of dysphagia including relevant complications of patients treated with the standardized out-of-hospital management were compared with those seen in the control group. The differences have distinct statistics meaning (p<0.01). Establishing a swallowing management protocol for outpatient setting can effectively help the recovery of the function of swallowing, reduce the incidence rate of dysphagia complications and improve the quality of life in patients with PD.

The objective of this study was to determine the seasonal pattern of group A streptococcal pharyngitis in children attended at a hospital emergency department in the Mediterranean island of Mallorca (Spain), and its association with meteorologic factors and schooling. We conducted a retrospective review of the medical records of children aged 1-15 years with a diagnosis of Streptococcus pyogenes pharyngitis between January 2006 and December 2011. The number of S. pyogenes pharyngitis was correlated to temperature, humidity, rainfall, atmospheric pressure, wind speed, solar radiation, and schooling, using regression and time series techniques. A total of 906 patients (median, 4 years old) with S. pyogenes pharyngitis, confirmed by throat culture, were attended during the study period. A seasonal pattern was observed with a peak activity in June and a minimum in September. Mean temperature, solar radiation, and school holidays were the best predicting variables ( R 2 = 0.68; p < 0.001 ). S. pyogenes activity increased with the decrease of mean temperature ( z = -2.4; p < 0.05), the increase of solar radiation ( z = 4.2; p < 0.001), and/or the decrease in school holidays ( z = -2.4; p < 0.05). In conclusion, S. pyogenes pharyngitis had a clear seasonality predominating in springtime, and an association with mean temperature, solar radiation, and schooling was observed. The resulting model predicted 68 % of S. pyogenes pharyngitis.

IMRT for head and neck cancer: reducing xerostomia and dysphagia

Dysphagia and xerostomia are the main sequellae of chemoradiotherapy for head and neck cancer, and the main factors in reducing long-term patient quality of life. IMRT uses advanced technology to focus the high radiation doses on the targets and avoid irradiation of non-involved tissues. The decisions about sparing organs and tissues whose damage causes xerostomia and dysphagia depends on the evidence for dose–response relationships for the organs causing these sequellae. This paper discusses the evidence for the contribution of radiotherapy to xerostomia via damage of the major salivary glands (parotid and submandibular) and minor salivary glands within the oral cavity, and the contribution of radiotherapy-related effect on important swallowing structures causing dysphagia. Recommendations for dose limits to these organs, based on measurements of xerostomia and dysphagia following radiotherapy, are provided here. PMID:27538846

Approximately 30% of patients with motor neuron disease (MND) present swallowing difficulties even in early disease stages. The aim of this study was to examine the usefulness of esophageal scintigraphy in detecting early stage of dysphagia in MND. Esophageal scintigraphy (ES) including mean transit time (MTT) estimation was performed in 121 MND patients presenting various levels of upper (UMN) and lower motor neuron (LMN) degeneration. ES detected dysphagia in more than 80% of MND patients who had referenced swallowing difficulties. In MND patients with ES-confirmed dysphagia, the MTT was increased approximately 2-fold without significant differences between the clinical phenotypes. The MTT was significantly longer in patients with bulbar-pseudobulbar syndrome in comparison to patients with isolated pseudobulbar syndrome, which indicates a higher involvement of the LMN deficiency in developing dysphagia in MND. The esophageal passage in MND was not dependent on age, sex, disease duration, or diagnosis delay. Interestingly, ES was also able to detect dysphagia in almost 70% of MND individuals who had no swallowing complaints (subclinical dysphagia). A more benign disease course and a higher percentage of male patients characterized this group. Esophageal scintigraphy is a helpful screening tool in determining early swallowing impairment in a high percent of patients with MND of various clinical phenotypes.

Background Consensus guidelines recommend that adults at low risk for group A streptococcal (GAS) pharyngitis be neither tested nor treated Objective To help patients decide when to visit a clinician for the evaluation of sore throat. Design Retrospective cohort study. Setting A national chain of retail health clinics. Patients 71 776 patients aged 15 years or older with pharyngitis who visited a clinic from September 2006 to December 2008. Measurements The authors created a score using information from patient-reported clinical variables plus the incidence of local disease and compared it with the Centor score and other traditional scores that require clinician-elicited signs. Results If patients aged 15 years or older with sore throat did not visit a clinician when the new score estimated the likelihood of GAS pharyngitis to be less than 10% instead of having clinicians manage their symptoms following guidelines that use the Centor score, 230 000 visits would be avoided in the United States each year and 8500 patients with GAS pharyngitis who would have received antibiotics would not be treated with them. Limitation Real-time information about the local incidence of GAS pharyngitis, which is necessary to calculate the new score, is not currently available. Conclusion A patient-driven approach to pharyngitis diagnosis that uses this new score could save hundreds of thousands of visits annually by identifying patients at home who are unlikely to require testing or treatment.

Oncologic treatments, such as curative radiotherapy and chemoradiation, for head and neck cancer can cause long-term swallowing impairments (dysphagia) that negatively impact quality of life. Radiation-induced dysphagia is comprised of a broad spectrum of structural, mechanical, and neurologic deficits. An understanding of the biomolecular effects of radiation on the time course of wound healing and underlying morphological tissue responses that precede radiation damage will improve options available for dysphagia treatment. The goal of this review is to discuss the pathophysiology of radiation-induced injury and elucidate areas that need further exploration. PMID:27098922

Background Oropharyngeal dysphagia is common in individuals after stroke. Taste and temperature are used in dysphagia rehabilitation. The influence of stimuli, such as taste and temperature, on swallowing biomechanics has been investigated in both healthy individuals and in individuals with neurological disease. However, some questions still remain unanswered, such as how the sequence of offered stimuli influences the pharyngeal response. The goal of the present study was to determine the influence of the sequence of stimuli, sour taste and cold temperature, on pharyngeal transit time during deglutition in individuals after stroke. Methods The study included 60 individuals with unilateral ischemic stroke, 29 males and 31 females, aged 41–88 years (mean age: 66.2 years) examined 0–50 days after ictus (median: 6 days), with mild to moderate oropharyngeal dysphagia. Exclusion criteria were hemorrhagic stroke patients, patients with decreased level of consciousness, and clinically unstable patients, as confirmed by medical evaluation. The individuals were divided into two groups of 30 individuals each. Group 1 received a nonrandomized sequence of stimuli (i.e. natural, cold, sour, and sour-cold) and group 2 received a randomized sequence of stimuli. A videofluoroscopic swallowing study was performed to analyze the pharyngeal transit time. Four different stimuli (natural, cold, sour, and sour-cold) were offered. The images were digitalized and specific software was used to measure the pharyngeal transit time. Since the values did not present regular distribution and uniform variances, nonparametric tests were performed. Results Individuals in group 1 presented a significantly shorter pharyngeal transit time with the sour-cold stimulus than with the other stimuli. Individuals in group 2 did not show a significant difference in pharyngeal transit time between stimuli. Conclusions The results showed that the sequence of offered stimuli influences the pharyngeal transit

Streptocara spp. infections are reported to cause gastritis, proventriculitis, esophagitis, and pharyngitis in various waterfowls, especially diving ducks. In the present paper, we describe severe fatal diphtheritic pharyngitis and esophagitis caused by Streptocara incognita in three female mute swans (Cygnus olor) in Bosnia and Herzegovina. Prior to death, the swans were showing signs of lethargy, anorexia, and reluctance to move. At necropsy, in all swans severe diphtheritic pharyngitis and esophagitis with deep, dark red hemorrhagic ulcerations were observed. Numerous thin, white, up to 1-cm-long nematodes, identified as S. incognita, were observed embedded in the pharyngeal and esophageal mucosa under the diphtheritic membranes. Histopathology revealed severe fibrinonecrotic inflammation with numerous cross-sections of the parasites. To the authors' knowledge, this is the first report of severe, fatal streptocariasis in mute swans.

We present a rare case of dermatomyosites associated with severe oropharyngeal dysphagia. A 13 year old female patient, being followed at the Rheumatologic Department, was referred to the Otolaryngology Department of the University of São Paulo School of Medicine Hospital. She complained of swallowing problems, especially with solids. Following our dysphagia study protocol, we employed a speech pathologist and otolaryngology evaluation, mainly for clinical history, examination of anatomical structures involved with swallowing events, cranium nerves integrity and videoendoscopic swallowing study. We diagnosed severe oropharyngeal dysphagia, with aspiration of saliva and food of all consistencies. We advised against oral feeding and recommended a diet through a gastric tube. She started with therapy and xerostomia medication, together with the treatment of the base disease. The patient showed a significant improvement, noticed by the clinical evaluation and the control videoendoscopic swallowing study, with the possibility of returning to oral feeding. The authors stress the incidence of oropharyngeal dysphagia in dermatomyosites and suggest the videoendoscopic swallowing study as a good exam for diagnosis and follow-up of these patients.

Pharyngeal pouches in mammals develop into specific derivatives. If the differentiation of the pharyngeal pouches is anomalous, their remnants can result in cysts, sinuses, and fistulae in the differentiated organs or around the neck. In the present study, we found several pharyngeal pouch remnants, such as cystic structures in thymus and parathyroid gland and fossulae extended from the piriform fossa, in the inbred cotton rats maintained at Hokkaido Institute of Public Health (HIS/Hiph) and University of Miyazaki (HIS/Mz). In HIS/Hiph, the fossulae extended from the apex of the piriform fossa into the thyroid glands and were lined with stratified squamous and cuboidal epithelium. Calcitonin-positive C-cells were present within their epithelium in HIS/Hiph. In contrast, the fossulae of HIS/Mz ran outside the thyroid glands toward the parathyroid glands; they were lined with columnar ciliated epithelium and a few goblet cells, but had no C-cells, which was consistent with the cystic structures in the thymus and the parathyroid gland. These results indicated that the fossulae were a remnant of the ultimobranchial body in HIS/Hiph and of the thymopharyngeal duct in HIS/Mz. Thus, the fossulae of the piriform fossa resembled the piriform sinus fistula in human. In conclusion, cotton rats frequently possessed pharyngeal pouch remnants, including the piriform sinus fistula, and therefore, might serve as a novel model to elucidate the mechanisms of pharyngeal pouch development.

2017-02-01

Research using animal models has contributed significantly to realizing the goal of understanding dysfunction and improving the care of patients who suffer from dysphagia. But why should other researchers and the clinicians who see patients day in and day out care about this work? Results from studies of animal models have the potential to change and grow how we think about dysphagia research and practice in general, well beyond applying specific results to human studies. Animal research provides two key contributions to our understanding of dysphagia. The first is a more complete characterization of the physiology of both normal and pathological swallow than is possible in human subjects. The second is suggesting of specific, physiological, targets for development and testing of treatment interventions to improve dysphagia outcomes.

Systemic vasculitis is a rare disease, and the diagnosis is very difficult when patient shows atypical symptoms. We experienced an unusual case of dysphagia caused by Churg-Strauss syndrome with lower cranial nerve involvement. A 74-year-old man, with a past history of sinusitis, asthma, and hearing deficiency, was admitted to our department for evaluation of dysphagia. He also complained of recurrent bleeding of nasal cavities and esophagus. Brain magnetic resonance imaging did not show definite abnormality, and electrophysiologic findings were suggestive of mononeuritis multiplex. Dysphagia had not improved after conventional therapy. Biopsy of the nasal cavity showed extravascular eosinophilic infiltration. All these findings suggested a rare form of Churg-Strauss syndrome involving multiple lower cranial nerves. Dysphagia improved after steroid therapy.

The prevalence of oropharyngeal dysphagia in older persons is high. Because it is frequently undetected, screening tests should be applied in risk groups. If the screening test is positive or typical risk factors are present, an instrumental assessment should be utilized. Objective diagnostic tools such as endoscopic evaluation and videofluoroscopy allow the description of the individual dysphagia pattern, which is the basis for an individualized treatment. The endoscopic evaluation of swallowing is increasingly used because it includes several advantages. Potential therapeutic strategies are multifaceted. The evidence for the effectiveness of adaptive, compensatory and rehabilitative strategies is growing, supporting the evolution of dysphagia therapy to an evidence based treatment. © Georg Thieme Verlag KG Stuttgart · New York.

Evaluate histories, clinical signs, and laboratory data of 69 horses homozygous by DNA testing for hyperkalemic periodic paralysis (HPP). Cohort study. 69 of 189 horses testing homozygous for HPP between October 1992 and November 1994. Questionnaires addressing signalment, training regimes, medical history, and current status of affected horses were sent to owners, trainers, or attending veterinarians. Data from completed questionnaires were tabulated and evaluated, using descriptive statistics. Sixty-nine (37%) of 189 questionnaires were completed and returned. Clinical episodes of muscle weakness or paralysis varied in severity and frequency from mild muscle fasciculations to recumbency and death. Sixty-three of 68 HPP-affected horses were reported to have had stridor associated with exercise, excitement, stress, or episodes of muscle paralysis. Common endoscopic findings in affected horses included pharyngeal collapse, pharyngeal edema, laryngopalatal dislocation, and laryngeal paralysis. Twelve of 27 horses receiving acetazolamide had decreases in stridor while receiving medication. Most horses testing homozygous for HPP had clinical signs associated with pharyngeal and laryngeal dysfunction. Hyperkalemic periodic paralysis should be included on a differential list for horses examined for signs of laryngeal or pharyngeal dysfunction or stridor. Treatment with acetazolamide may help to control respiratory tract signs associated with this disease.

Abstract Background: Dysphagia is a well-known complication following anterior cervical spine surgery. Although risk factors for dysphagia have been reported in the literature, they still remain controversial. This study aims to investigate the risk factors associated with dysphagia following anterior cervical spinal surgery. Methods: PubMed, EMBASE, and The Cochrane Library were searched up to June 2016 for studies examining dysphagia following anterior cervical spinal surgery. Risk factors associated with dysphagia were extracted. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for outcomes. Data analysis was conducted with RevMan 5.3 and STATA 12.0. Results: The final analysis includes a total of 18 distinct studies. The pooled analysis reveals that there are significant differences in female gender (OR = 2.30, 95% CI: 1.76–2.99, P < 0.001), the use of anterior cervical plate (OR = 1.66, 95% CI: 1.05–2.62, P = 0.03), more than 1 surgical level (OR = 2.07, 95% CI: 1.62–2.66, P < 0.001), the upper surgical level at C3/4 (OR = 3.08, 95% CI: 1.44–6.55, P = 0.004), and the use of bone morphogenetic protein-2 (rhBMP-2) (OR = 5.52, 95% CI: 2.16–14.10, P < 0.001). However, no significant difference is found in revision surgery (OR = 1.67, 95% CI: 0.60–4.68, P = 0.33), the type of fusion (OR = 1.02, 95% CI: 0.62–1.67, P = 0.95), and cervical disc arthroplasty (OR = 1.37, 95% CI: 0.75–2.51, P = 0.30). Conclusion: Female gender, the use of anterior cervical plate, more than 1 surgical level, the upper surgical level at C3/4, and the use of rhBMP-2 are the risk factors for dysphagia following anterior cervical spinal surgery. However, revision surgery, the type of fusion, and cervical disc arthroplasty are unassociated with dysphagia. Considering the limited number of studies, this conclusion should be interpreted cautiously, and larger scale studies are required. PMID

Fundoplication surgery is a commonly performed procedure for gastro-esophageal reflux disease or hiatal hernia repair. Up to 10% of patients develop persistent postoperative dysphagia after surgery. Data on the effectiveness of pneumatic dilation for treatment are limited. The aim of this study was to evaluate clinical outcomes and identify clinical factors associated with successful response to pneumatic dilation among patients with persistent postfundoplication dysphagia (PPFD). We retrospectively evaluated patients who had undergone pneumatic dilation for PPFD between 1999 and 2016. Patients with dysphagia or achalasia prior to fundoplication were excluded. Demographic information, surgical history, severity of dysphagia, and clinical outcomes were collected. Data pertaining to esophagram, manometry, endoscopy, and pneumatic dilation were also collected. We identified 38 patients (82% female, 95% Caucasian, and median age 59 years) with PPFD who completed pneumatic dilation. The median postfundoplication dysphagia score was 2. Eleven patients had abnormal peristalsis on manometry. Seventeen patients reported response (seven complete) with an average decrease of 1 in their dysphagia score. Fifteen patients underwent reoperation due to PPFD. Hiatal hernia repair was the only factor that predicts a higher response rate to pneumatic dilation. Only one patient in our study developed complication (pneumoperitoneum) from pneumatic dilation. We found that pneumatic dilation to be a safe treatment option for PPFD with moderate efficacy. Patients who developed PPFD after a hiatal hernia repair may gain the greatest benefit after pneumatic dilation. We were not able to identify additional clinical, radiological, endoscopic, or manometric parameters that were predictive of response. © 2017 John Wiley & Sons Ltd.

Prevalence of oropharyngeal dysphagia in Parkinson's disease: a meta-analysis.

2012-05-01

Dysphagia is a potentially harmful feature, also in Parkinson's disease (PD). As published prevalence rates vary widely, we aimed to estimate the prevalence of oropharyngeal dysphagia in PD in a meta-analysis. We conducted a systematic literature search in February 2011 and two independent reviewers selected the papers. We computed the estimates of the pooled prevalence weighted by sample size. Twelve studies were suitable for calculating prevalence rates. Ten studies provided an estimate based on subjective outcomes, which proved statistically heterogeneous (p < 0.001), with a pooled prevalence estimate with random effect analysis of 35% (95% CI 28-41). Four studies provided an estimate based on objective measurements, which were statistically homogeneous (p = 0.23), with a pooled prevalence estimate of 82% (95% CI 77-87). In controls the pooled subjective prevalence was 9% (95% CI 2-17), while the pooled objective prevalence was 23% (95% CI 13-32). The pooled relative risk was 3.2 for both subjective outcomes (95% CI 2.32-4.41) and objective outcomes (95% CI 2.08-4.98). Clinical heterogeneity between studies was chiefly explained by differences in disease severity. Subjective dysphagia occurs in one third of community-dwelling PD patients. Objectively measured dysphagia rates were much higher, with 4 out of 5 patients being affected. This suggests that dysphagia is common in PD, but patients do not always report swallowing difficulties unless asked. This underreporting calls for a proactive clinical approach to dysphagia, particularly in light of the serious clinical consequences. Copyright © 2011 Elsevier Ltd. All rights reserved.

Sarcopenia can cause varying physical function disorders, including dysphagia. Malnutrition, a potential result of dysphagia, can also cause sarcopenia. However, the association between sarcopenia and dysphagia is not fully understood, despite evidence suggesting correlations between deglutition disorders and degenerative loss of muscle mass. The present study investigated the prevalence of dysphagia among patients with sarcopenia, and the association between the two conditions. We included 224 older adults (mean age 82.5 ± 8.4 years; 37.9% men). Individuals who had a stroke or other diseases that could directly cause dysphagia were excluded. Logistic regression analyses were carried out after adjusting for potential causes of sarcopenia, including malnutrition, a low activity of daily living levels and aging, to investigate the relationship between the skeletal muscle index (SMI), prevalence of sarcopenia diagnosed based on a low SMI and grip strength, and swallowing functions. The Mini-Nutritional Assessment short form was used to assess their nutritional status, and the Barthel Index was used to evaluate their activities of daily living. The prevalences of sarcopenia and dysphagia were 76.8% and 30.0%, respectively. Multivariate analysis showed that Barthel Index, SMI and presence of sarcopenia were significant independent factors for the prevalence of dysphagia, after adjusting for sex, age and nutritional status. Furthermore, subgroup analysis showed that SMI in males, and both hand-grip strength and SMI in females were lower in dysphagic subjects than in non-dysphagic subjects (P ≤ 0.01). Sarcopenia was an independent risk factor for dysphagia among older individuals. However, further studies are required to define causality. © 2015 Japan Geriatrics Society.

Does evolutionary innovation in pharyngeal jaws lead to rapid lineage diversification in labrid fishes?

PubMed Central

2009-01-01

Background Major modifications to the pharyngeal jaw apparatus are widely regarded as a recurring evolutionary key innovation that has enabled adaptive radiation in many species-rich clades of percomorph fishes. However one of the central predictions of this hypothesis, that the acquisition of a modified pharyngeal jaw apparatus will be positively correlated with explosive lineage diversification, has never been tested. We applied comparative methods to a new time-calibrated phylogeny of labrid fishes to test whether diversification rates shifted at two scales where major pharyngeal jaw innovations have evolved: across all of Labridae and within the subclade of parrotfishes. Results Diversification patterns within early labrids did not reflect rapid initial radiation. Much of modern labrid diversity stems from two recent rapid diversification events; one within julidine fishes and the other with the origin of the most species-rich clade of reef-associated parrotfishes. A secondary pharyngeal jaw innovation was correlated with rapid diversification within the parrotfishes. However diversification rate shifts within parrotfishes are more strongly correlated with the evolution of extreme dichromatism than with pharyngeal jaw modifications. Conclusion The temporal lag between pharyngeal jaw modifications and changes in diversification rates casts doubt on the key innovation hypothesis as a simple explanation for much of the richness seen in labrids and scarines. Although the possession of a secondarily modified PJA was correlated with increased diversification rates, this pattern is better explained by the evolution of extreme dichromatism (and other social and behavioral characters relating to sexual selection) within Scarus and Chlorurus. The PJA-innovation hypothesis also fails to explain the most dominant aspect of labrid lineage diversification, the radiation of the julidines. We suggest that pharyngeal jaws might have played a more important role in enabling

Dysphagia is common in inflammatory myopathies and usually responds to corticosteroids. Severe dysphagia requiring feeding by percutaneous endoscopic gastrostomy is associated with significant morbidity and high mortality. A 56-year old African Black woman initially presented with systemic sclerosis (SSC) - myositis overlap and interstitial lung disease. She responded to high dose corticosteroids and cyclophosphamide followed by azathioprine, with improvement in her lung function and regression of the skin changes. Six years later she had a myositis flare with severe dysphagia. Her myositis improved after high doses of corticosteroids, azathioprine and two doses of intravenous immunoglobulin (IVIG). As her dysphagia persisted, she was fed via a percutaneous endoscopic gastrostomy (PEG) tube and given a course of rituximab. Her dysphagia gradually resolved and the PEG tube was removed within two months. She received another dose of rituximab six months later and continued low dose prednisone and azathioprine. Her muscle power improved, weight returned to normal and she remained well 20 months after hospital discharge. Our patient with SSC-myositis overlap and severe dysphagia requiring PEG feeding, improved with high dose corticosteroids, azathioprine, two courses of IVIG and rituximab, and remained in remission 20 months after hospital discharge.

Esophageal dysphagia is common in gastroenterology practice and has multiple etiologies. A complication for some patients with dysphagia is food impaction. A valid and reliable questionnaire to rapidly evaluate esophageal dysphagia and impaction symptoms can aid the gastroenterologist in gathering information to inform treatment approach and further evaluation, including endoscopy. 1638 patients participated over two study phases. 744 participants completed the Brief Esophageal Dysphagia Questionnaire (BEDQ) for phase 1; 869 completed the BEDQ, Visceral Sensitivity Index, Gastroesophageal Reflux Disease Questionnaire, and Hospital Anxiety and Depression Scale for phase 2. Demographic and clinical data were obtained via the electronic medical record. The BEDQ was evaluated for internal consistency, split-half reliability, ceiling and floor effects, and construct validity. The BEDQ demonstrated excellent internal consistency, reliability, and construct validity. The symptom frequency and severity scales scored above the standard acceptable cutoffs for reliability while the impaction subscale yielded poor internal consistency and split-half reliability; thus the impaction items were deemed qualifiers only and removed from the total score. No significant ceiling or floor effects were found with the exception of 1 item, and inter-item correlations fell within accepted ranges. Construct validity was supported by moderate yet significant correlations with other measures. The predictive ability of the BEDQ was small but significant. The BEDQ represents a rapid, reliable, and valid assessment tool for esophageal dysphagia with food impaction for clinical practice that differentiates between patients with major motor dysfunction and mechanical obstruction. © 2016 John Wiley & Sons Ltd.

The implication of dysphagia for people treated nonsurgically for head and neck cancer (HNC) and its detrimental effects on functioning and quality of life has been well documented. To date, however, there has been a paucity of research on the effects of dysphagia following HNC on carers, independent of the consequences of a gastrostomy. The objective of this qualitative study was to report on the experiences of carers of people with dysphagia (non-gastrostomy dependent) following nonsurgical treatment for HNC and to identify the support needs of this group. A purposive, maximum-variation sampling technique was adopted to recruit 12 carers of people treated curatively for HNC since 2007. Each participated in an in-depth interview, detailing their experience of caring for someone with dysphagia and the associated impact on their life. Thematic analysis was adopted to search the transcripts for key phases and themes that emerged from the discussions. Analysis of the transcripts revealed four themes: (1) dysphagia disrupts daily life, (2) carers make adjustments to adapt to their partner's dysphagia, (3) the disconnect between carers' expectations and the reality of dysphagia, and (4) experiences of dysphagia-related services and informal supports. Carers generally felt ill-prepared for their role in dysphagia management. The qualitative methodology successfully described the impact of dysphagia on the everyday lives of carers, particularly in regard to meal preparation, social events, and family lifestyle. Clinicians should provide adequate and timely training and support to carers and view carers as copartners in dysphagia management.

Dysphagia in Parkinson's disease is responsive to levodopa.

The role of levodopa in the treatment of dysphagia in Parkinson's disease (PD) has recently been questioned. There are good reasons, however, to "question the question." In this essay, evidence from published literature and clinical experience is presented, as well as a critical review of the first meta-analysis to explore this issue. The evidence presented supports the traditional view that PD dysphagia is responsive to levodopa. Copyright © 2012. Published by Elsevier Ltd.

The reasons for aspiration in healthy adults remain unknown. Given that the pharyngeal phase of swallowing is a key component of the safe swallow, it was hypothesized that healthy older adults who aspirate are likely to generate less pharyngeal peak pressures when swallowing. Accordingly, pharyngeal and upper esophageal sphincter pressures were examined as a function of aspiration status (i.e., nonaspirator vs. aspirator), sensor location (upper vs. lower pharynx), liquid type (i.e., water vs. milk), and volume (i.e., 5 vs. 10 ml) in healthy older adults. Manometric measurements were acquired with a 2.1-mm catheter during flexible endoscopic evaluation. Participants (N = 19, mean age = 79.2 years) contributed 28 swallows; during 8 swallows, simultaneous manometric measurements of upper and lower pharyngeal and upper esophageal pressures were obtained. Pharyngeal manometric peak pressure was significantly less for aspirators (mean = 82, SD = 31 mmHg) than for nonaspirators (mean = 112, SD = 20 mmHg), and upper pharyngeal pressures (mean = 85, SD = 32 mmHg) generated less pressure than lower pharyngeal pressures (mean = 116, SD = 38 mmHg). Manometric measurements vary with respect to aspiration status and sensor location. Lower pharyngeal pressures in healthy older adults may predispose them to aspiration. PMID:20623303

In this paper, the authors investigate the effects of anterior cervical decompression (ACD) on swallowing and vocal function. The study comprised 114 patients who underwent ACD. The early group (50 patients) was examined immediately pre- and postoperatively, and the late group (64 patients) was examined at only 3 to 9 months postoperatively. Fifty age- and sex-matched patients from the Department of Otorhinolaryngology-Head and Neck Surgery who had not been intubated in the previous 5 years were used as a control group. All patients in the early and control groups were examined by a laryngologist; patients in the late group were examined by a laryngologist and a neurosurgeon. Videolaryngostroboscopy was performed in all members of the patient and control groups, and the function of the ninth through 12th cranial nerves were clinically evaluated. Data were collected concerning swallowing, voice quality, surgery results, and health-related quality of life. Patients with persistent dysphonia were referred for phoniatric evaluation and laryngeal electromyography (EMG). Those with persistent dysphagia underwent transoral endoscopic evaluation of swallowing function and videofluorography. Sixty percent of patients in the early group reported dysphonia and 69% reported dysphagia at the immediate postoperative visit. Unilateral vocal fold paresis occurred in 12%. The prevalence of both dysphonia and dysphagia decreased in both groups 3 to 9 months postoperatively. All six patients with vocal fold paresis in the early group recovered, and in the late group there were two cases of vocal fold paresis. The results of laryngeal EMG were abnormal in 14 of 16 patients with persistent dysphonia. Neither intraoperative factors nor age or sex had any effect on the occurrence of dysphonia, dysphagia, or vocal fold paresis. Most patients were satisfied with the surgical outcome. Dysphonia, dysphagia, and vocal fold paresis are common but usually transient complications of ACD

The high prevalence of dysphagia after stroke leads to increased mortality, and cerebral reperfusion therapy has been effective in reducing neurologic deficits. The aim of this study was to investigate the severity and evolution of dysphagia and the occurrence of pneumonia in patients submitted to cerebral reperfusion therapy. Seventy ischemic stroke patients were evaluated. Of these, 35 patients (group 1) were submitted to cerebral reperfusion therapy and 35 (group 2) did not receive thrombolytic treatment. The following were evaluated: severity of dysphagia by means of videofluoroscopy, evolution of oral intake rate by means of the Functional Oral Intake Scale, and the occurrence of pneumonia by international protocol. The relation between the severity of dysphagia and the occurrence of pneumonia with the treatment was evaluated through the chi-square test; the daily oral intake rate and its relation to the treatment were assessed by the Mann-Whitney test and considered significant if P is less than .05. The moderate and severe degrees of dysphagia were more frequent (P=.013) among the patients who were not submitted to cerebral reperfusion therapy. The daily oral intake evolved independently of the treatment type, without statistical significance when compared between the groups, whereas pneumonia occurred more frequently in group 2 (28%) in relation to group 1 (11%) and was associated with the worst degrees of dysphagia (P=.045). We can conclude that there is improvement in the oral intake rate in both groups, with lower severity of dysphagia and occurrence of pneumonia in ischemic stroke patients submitted to cerebral reperfusion therapy.

Stroke-associated pneumonia is a frequent complication after stroke associated with poor outcome. Dysphagia is a known risk factor for stroke-associated pneumonia but accumulating evidence suggests that stroke induces an immunodepressive state increasing susceptibility for stroke-associated pneumonia. We aimed to confirm that stroke-induced immunodepression syndrome is associated with stroke-associated pneumonia independently from dysphagia by investigating the predictive properties of monocytic HLA-DR expression as a marker of immunodepression as well as biomarkers for inflammation (interleukin-6) and infection (lipopolysaccharide-binding protein). This was a prospective, multicenter study with 11 study sites in Germany and Spain, including 486 patients with acute ischemic stroke. Daily screening for stroke-associated pneumonia, dysphagia and biomarkers was performed. Frequency of stroke-associated pneumonia was 5.2%. Dysphagia and decreased monocytic HLA-DR were independent predictors for stroke-associated pneumonia in multivariable regression analysis. Proportion of pneumonia ranged between 0.9% in the higher monocytic HLA-DR quartile (≥21,876 mAb/cell) and 8.5% in the lower quartile (≤12,369 mAb/cell). In the presence of dysphagia, proportion of pneumonia increased to 5.9% and 18.8%, respectively. Patients without dysphagia and normal monocytic HLA-DR expression had no stroke-associated pneumonia risk. We demonstrate that dysphagia and stroke-induced immunodepression syndrome are independent risk factors for stroke-associated pneumonia. Screening for immunodepression and dysphagia might be useful for identifying patients at high risk for stroke-associated pneumonia.

Neoadjuvant therapy is commonly administered to patients with localized disease who have T3-4 esophageal disease as staged by endoscopic ultrasound (EUS). Previously, we noted that patients who present with dysphagia have a higher EUS T stage. We hypothesized that the presence of dysphagia is predictive of EUS T3-4 disease and that staging EUS could be forgone for esophageal cancer patients with dysphagia. We performed a prospective, intent-to-treat, single-cohort study in which patients with potentially resectable esophageal cancer completed a standardized four-tier dysphagia score survey. EUS was performed as part of our standard evaluation. To determine whether the presence of dysphagia predicted EUS T3-4 disease, the dysphagia score was compared with EUS T stage. The study enrolled 114 consecutive patients between August 2012 and February 2014: 77% (88 of 114) received neoadjuvant therapy, 18% (20 of 114) did not, and 5% (6 of 114) pursued treatment elsewhere. In total, 70% (80 of 114) underwent esophagectomy; of these, 54% (61 of 114) had dysphagia and 46% (53 of 114) did not. Dysphagia scores were 66% (40 of 61) grade 1, 25% (15 of 61) grade 2, and 10% (6 of 61) grade 3 to 4. Among patients with dysphagia, 89% (54 of 61) had T3-4 disease by EUS; among those without dysphagia, only 53% (28 of 53) had T3-4 disease by EUS (p < 0.001). The presence of dysphagia in patients with esophageal cancer was highly predictive of T3-4 disease by EUS. On the basis of this finding, approximately 50% of patients currently undergoing staging EUS at our institution could potentially forgo EUS before neoadjuvant therapy. Patients without dysphagia, however, should still undergo EUS. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Research using animal models has contributed significantly to realizing the goal of understanding dysfunction and improving the care of patients who suffer from dysphagia. But why should other researchers and the clinicians who see patients day in and day out care about this work? Results from studies of animal models have the potential to change and grow how we think about dysphagia research and practice in general, well beyond applying specific results to human studies. Animal research provides two key contributions to our understanding of dysphagia. The first is a more complete characterization of the physiology of both normal and pathological swallow than is possible in human subjects. The second is suggesting of specific, physiological, targets for development and testing of treatment interventions to improve dysphagia outcomes. PMID:28132098

IMRT for head and neck cancer: reducing xerostomia and dysphagia.

PubMed

Wang, XiaoShen; Eisbruch, Avraham

2016-08-01

Dysphagia and xerostomia are the main sequellae of chemoradiotherapy for head and neck cancer, and the main factors in reducing long-term patient quality of life. IMRT uses advanced technology to focus the high radiation doses on the targets and avoid irradiation of non-involved tissues. The decisions about sparing organs and tissues whose damage causes xerostomia and dysphagia depends on the evidence for dose-response relationships for the organs causing these sequellae. This paper discusses the evidence for the contribution of radiotherapy to xerostomia via damage of the major salivary glands (parotid and submandibular) and minor salivary glands within the oral cavity, and the contribution of radiotherapy-related effect on important swallowing structures causing dysphagia. Recommendations for dose limits to these organs, based on measurements of xerostomia and dysphagia following radiotherapy, are provided here. © The Author 2016.

Multiple sclerosis is a chronic neurological disease that may cause swallowing disorders. Dysphagia is a common problem, which patients with different levels of disability may encounter, but it is usually underestimated; therefore, effective assessments need to be performed before any serious complications. The aim of this study was to identify the frequency and characteristics of dysphagia in multiple sclerosis patients of Khuzestan MS society, using a Persian version of Dysphagia in Multiple Sclerosis (DYMUS) questionnaire. 105 consecutive MS patients (84 F and 21 M, mean age 33.8 ± 8.5 years, mean disease duration 3.5 ± 3.1 years, mean Expanded Disability Status Scale (EDSS) 1.8 ± 1.3) participated in the study and the DYMUS questionnaire was administered by a trained speech therapist. The results have shown that 55 MS patients (52.4%) had dysphagia and the dysphagia was significantly associated with the disease course of MS (p = 0.02). However, significant associations between DYMUS values and EDSS, disease duration, age, and gender were not observed. (Respectively, p = 0.4, p = 0.09, p = 0.1, p = 1.0). In the dysphagia group, based on dysphagia severity, 17.1% and 35.2% of patients had mild and alarming dysphagia, respectively. Although, the patients with alarming dysphagia had longer disease duration, higher EDSS score and more with SP, PP and PR disease course than the patients with mild dysphagia, these differences were not significant. The oropharyngeal dysphagia in MS patients is very common even in early stages of the disease; therefore, it is important to assess these patients carefully and to initiate a treatment program if needed.

Pressure-flow analysis allows assessing esophageal bolus transport in relation to esophageal pressures. This study aimed to characterize pressure-flow metrics in relation to dysphagia in paediatric patients. We analysed esophageal pressure-impedance recordings of 5 ml liquid and viscous swallows from 35 children (17 M, mean 10.5 ± 0.8 years). Primary indication for referral was gastroesophageal reflux disease (GERD) (9), post-fundoplication dysphagia (5), idiopathic dysphagia (16), trachea-esophageal fistula (2) and other (3). Peristaltic function was assessed using the 20 mmHg iso-contour defect and the timing between bolus pressure and flow was assessed using the Pressure Flow Index, a metric elevated in relation to dysphagia. Patients were stratified in relation to dysphagia and to peristaltic defect size. Dysphagia was characterized by a weaker peristalsis for liquids and higher Pressure Flow Index for viscous. When patients were stratified based on weak or normal peristalsis, dysphagia with weak peristalsis related to a larger iso-contour defect size and dysphagia with normal peristalsis related to higher Pressure Flow Index. Pressure-flow analysis enables differentiation of patients with dysphagia due to weak peristalsis (poor bolus clearance) from abnormal bolus flow resistance (esophageal outflow obstruction). This new dichotomous categorization of esophageal function may help guide the selection of optimal treatment such as pharmacological or endoscopic therapy. • Pressure-flow analysis (PFA) can detect abnormalities in esophageal motility using integrated analysis of bolus propulsion and bolus flow during swallowing. • AIM analysis has recently been reported to be useful in identifying subtle pre-operative esophageal dysfunction in adult patients who developed post-fundoplication dysphagia as well as in patients with non-obstructive dysphagia. • Pressure-flow parameters can distinguish the cause of dysphagia in paediatric patients. • Combined

Objective Patient-reported outcome (PRO) measures are commonly used to capture patient experience with dysphagia and to evaluate treatment effectiveness. Inappropriate application can lead to distorted results in clinical studies. A systematic review of the literature on dysphagia-related PRO measures was performed to 1) identify all currently available measures and 2) to evaluate each for the presence of important measurement properties that would affect their applicability. Design MEDLINE via the PubMed interface, the Cumulative Index of Nursing and Allied Health Literature, and the Health and Psychosocial Instrument database were searched using relevant vocabulary terms and key terms related to PRO measures and dysphagia. Three independent investigators performed abstract and full text reviews. Each study meeting criteria was evaluated using an 18-item checklist developed a priori that assessed multiple domains: 1) conceptual model, 2) content validity, 3) reliability, 4) construct validity, 6) scoring and interpretation, and 7) burden and presentation. Results Of 4950 abstracts reviewed, a total of 34 dysphagia-related PRO measures (publication year 1987 – 2014) met criteria for extraction and analysis. Several PRO measures were of high quality (MADS for achalasia, SWAL-QOL and SSQ for oropharyngeal dysphagia, PROMIS-GI for general dysphagia, EORTC-QLQ-OG25 for esophageal cancer, ROMP-swallowing for Parkinson’s disease, DSQ-EoE for eosinophilic esophagitis, and SOAL for total laryngectomy-related dysphagia). In all, 17 met at least one criterion per domain. Thematic deficiencies in current measures were evident including: 1) direct patient involvement in content development, 2) empirically justified dimensionality, 3) demonstrable responsiveness to change, 4) plan for interpreting missing responses, and 5) literacy level assessment. Conclusion This is the first comprehensive systematic review assessing developmental properties of all available dysphagia

This study compared the effectiveness of different methods of instruction for the oral and pharyngeal cancer examination. A group of thirty sophomore students at the University of Florida College of Dentistry were randomly assigned to three training groups: video instruction, a faculty-led hands-on instruction, or both video and hands-on instruction. The training intervention involved attending two sessions spaced two weeks apart. The first session used a pretest to assess students' baseline didactic knowledge and clinical examination technique. The second session utilized two posttests to assess the comparative effectiveness of the training methods on didactic knowledge and clinical technique. The key findings were that students performed the clinical examination significantly better with the combination of video and faculty-led hands-on instruction (p<0.01). All students improved their clinical exam skills, knowledge, and confidence in performing the oral and pharyngeal cancer examination independent of which training group they were assigned. Utilizing both video and interactive practice promoted greater performance of the clinical technique on the oral and pharyngeal cancer examination.

Oculopharyngeal muscular dystrophy (OPMD) is a late-onset autosomal dominant inherited dystrophy caused by an abnormal trinucleotide repeat expansion in the poly(A)-binding-protein-nuclear 1 (PABPN1) gene. Primary muscular targets of OPMD are the eyelid elevator and pharyngeal muscles, including the cricopharyngeal muscle (CPM), the progressive involution of which leads to ptosis and dysphagia, respectively. To understand the consequences of PABPN1 polyalanine expansion in OPMD, we studied muscle biopsies from 14 OPMD patients, 3 inclusion body myositis patients, and 9 healthy controls. In OPMD patient CPM (n = 6), there were typical dystrophic features with extensive endomysial fibrosis and marked atrophy of myosin heavy-chain IIa fibers. There were more PAX7-positive cells in all CPM versus other muscles (n = 5, control; n = 3, inclusion body myositis), and they were more numerous in OPMD CPM versus control normal CPM without any sign of muscle regeneration. Intranuclear inclusions were present in all OPMD muscles but unaffected OPMD patient muscles (i.e. sternocleidomastoid, quadriceps, or deltoid; n = 14) did not show evidence of fibrosis, atrophy, or increased PAX7-positive cell numbers. These results suggest that the specific involvement of CPM in OPMD might be caused by failure of the regenerative response with dysfunction of PAX7-positive cells and exacerbated fibrosis that does not correlate with the presence of PABPN1 inclusions.

The videofluoroscopic dysphagia scale (VDS) was developed as an objective predictor of the prognosis of dysphagia after stroke. We evaluated the clinical validity of the VDS for various diseases. We reviewed the medical records of 1,995 dysphagic patients (1,222 men and 773 women) who underwent videofluoroscopic studies in Seoul National University Hospital from April 2002 through December 2009. Their American Speech–Language–Hearing Association’s National Outcome Measurement System (ASHA NOMS) swallowing scale, clinical dysphagia scale (CDS), and VDS scores were evaluated on the basis of the clinical and/or videofluoroscopic findings by the consensus of two physiatrists. The correlations between the VDS and the other scales were calculated. The VDS displayed significant correlations with the ASHA NOMS swallowing scale and the CDS in every disease group (p < 0.001 in all groups, including central and peripheral nervous system disorders), and these correlations were more apparent for spinal cord injury, peripheral nerve system disorders, and neurodegenerative diseases (correlation coefficients between the VDS and the ASHA NOMS swallowing scale: −0.603, −0.602, and −0.567, respectively). This study demonstrated that the VDS is applicable to dysphagic patients with numerous etiologies that cause dysphagia

OBJECTIVE: Before the advanced evaluation of deglutition and selection of a treatment method, objective screening methods are necessary for patients with dysphagia. In this study a new electroclinical test was established to evaluate patients with dysphagia. METHODS: This test is based on determining piecemeal deglutition; which is a physiological phenomenon occurring when a bolus of a large volume is divided into two or more parts which are swallowed successively. The combined electrophysiological and mechanical method used to record laryngeal movements detected by a piezoelectric transducer, and activities of the related submental integrated EMG (SM-EMG)-and sometimes the cricopharyngeal muscle of the upper oesophageal sphincter (CP-EMG)-were performed during swallowing. Thirty normal subjects and 66 patients with overt dysphagia of neurogenic origin were investigated after detailed clinical evaluation. Twenty patients with a potential risk of dysphagia, but who were normal clinically at the time of investigation, were also evaluated to determine the specificity of the test. All subjects were instructed to swallow doses of water, gradually increasing in quantity from 1 ml to 20 ml, and any recurrence of the signals related to swallowing within the eight seconds was accepted as a sign of dysphagia limit. RESULTS: In normal subjects as well as in the patients without dysphagia, piecemeal deglutition was never seen with less than 20 ml water. This volume was therefore accepted as the lower limit of piecemeal deglutition. In patients with dysphagia, dysphagia limits were significantly lower than those of normal subjects. CONCLUSION: The method is a highly specific and sensitive test for the objective evaluation of oropharyngeal dysphagia even in patients with suspected dysphagia of neurogenic origin. It can also be safely and simply applied in any EMG laboratory. PMID:8937344

2016-06-01

Identification of pharyngeal residue severity located in the valleculae and pyriform sinuses has always been a primary goal during fiberoptic endoscopic evaluation of swallowing (FEES). Pharyngeal residue is a clinical sign of potential prandial aspiration making an accurate description of its severity an important but difficult challenge. A reliable, validated, and generalizable pharyngeal residue severity rating scale for FEES would be beneficial. A systematic review of the published English language literature since 1995 was conducted to determine the quality of existing pharyngeal residue severity rating scales based on FEES. Databases were searched using controlled vocabulary words and synonymous free text words for topics of interest (deglutition disorders, pharyngeal residue, endoscopy, videofluoroscopy, fiberoptic technology, aspiration, etc.) and outcomes of interest (scores, scales, grades, tests, FEES, etc.). Search strategies were adjusted for syntax appropriate for each database/platform. Data sources included MEDLINE (OvidSP 1946-April Week 3 2015), Embase (OvidSP 1974-2015 April 20), Scopus (Elsevier), and the unindexed material in PubMed (NLM/NIH) were searched for relevant articles. Supplementary efforts to identify studies included checking reference lists of articles retrieved. Scales were compared using qualitative properties (sample size, severity definitions, number of raters, and raters' experience and training) and psychometric analyses (randomization, intra- and inter-rater reliability, and construct validity). Seven articles describing pharyngeal residue severity rating scales met inclusion criteria. Six of seven scales had insufficient data to support their use as evidenced by methodological weaknesses with both qualitative properties and psychometric analyses. There is a need for qualitative and psychometrically reliable, validated, and generalizable pharyngeal residue severity rating scales that are anatomically specific, image

Background The purpose of this study was to assess the association between skeletal muscle mass, activities of daily living (ADLs) and severe dysphagia in cancer patients. Methods A nested case-control study was performed in 111 consecutive cancer patients with dysphagia who were prescribed speech therapy. Skeletal muscle mass comprising the cross-sectional area of the left and right psoas muscles was assessed via abdominal computed tomography at the third lumbar vertebral level. ADLs were evaluated by the Barthel Index. The severity of dysphagia was assessed by the Food Intake Level Scale and was characterized by non-oral feeding or oral food intake at discharge. Univariate and logistic regression analyses were applied to examine the associations between dysphagia, skeletal muscle index (SMI) and ADLs. Results There were 86 men and 25 women (mean age, 70 years). The mean SMI was 5.68 ± 1.74 cm2/m2 in men and 4.43 ± 1.21 cm2/m2 in women. The median Barthel Index score was 20. Thirty-three patients were on non-oral feeding at discharge. The mean SMI did not differ significantly between non-oral feeding and oral food intake groups in t-test. The median Barthel Index score was lower in the non-oral feeding group in Mann–Whitney U test. Logistic regression analysis of the severity of dysphagia adjusted for age, sex, SMI, Barthel Index score, serum albumin, cancer type and stage, and vocal cord paralysis showed that SMI was associated independently with oral food intake at discharge. Barthel Index score showed a tendency to be associated with oral food intake. Conclusions Skeletal muscle mass is associated with severe dysphagia in cancer patients. ADLs show a tendency to be associated with severe dysphagia in cancer patients. PMID:26673551

Background Dysphagia occurs in up to 20% of patients with a recent small subcortical infarct, even when excluding brainstem infarcts. Aim To examine the impact of lesion topography and concomitant cerebrovascular lesions on the occurrence of dysphagia in patients with a single supratentorial recent small subcortical infarct. Methods We retrospectively identified all inpatients with magnetic resonance imaging-confirmed supratentorial recent small subcortical infarcts over a five-year period. Dysphagia was determined by speech-language therapists. Recent small subcortical infarcts were compiled into a standard brain model and compared using lesion probability maps. Furthermore, magnetic resonance imaging scans were reviewed for the combination of both acute and old cerebrovascular lesions. Results A total of 243 patients with a recent small subcortical infarct were identified (mean age 67.9 ± 12.2 years). Of those, 29 had mild and 18 moderate-to-severe dysphagia. Lesion probability maps suggested no recent small subcortical infarct location favoring the occurrence of moderate-to-severe dysphagia. However, patients with moderate-to-severe dysphagia more frequently showed combined damage to both pyramidal tracts by the recent small subcortical infarct and a contralateral old lesion (lacune: 77.8% vs. 19.9%, p < 0.001; lacune or confluent white matter hyperintensities: 100% vs. 57.7%, p < 0.001) than patients without swallowing dysfunction. Comparable results were obtained when analyzing patients with any degree of dysphagia. Conclusions Preexisting contralateral vascular pyramidal tract lesions are closely related to the occurrence of moderate-to-severe dysphagia in patients with supratentorial recent small subcortical infarcts.

Pharyngeal diameter in various head and neck positions during exercise in sport horses

PubMed Central

2014-01-01

Background In equine athletes, dynamic stenotic disorders of the upper airways are often the cause for abnormal respiratory noises and/or poor performance. There are hypotheses, that head and neck flexion may influence the morphology and function of the upper airway and thus could even induce or deteriorate disorders of the upper respiratory tract. Especially the pharynx, without osseous or cartilaginous support is prone to changes in pressure and airflow during exercise. The objective of this study was to develop a method for measuring the pharyngeal diameter in horses during exercise, in order to analyse whether a change of head-neck position may have an impact on the pharyngeal diameter. Results Under the assumption that the width of the epiglottis remains constant in healthy horses, the newly developed method for calculating the pharyngeal diameter in horses during exercise is unsusceptible against changes of the viewing-angle and distance between the endoscope and the structures, which are to be assessed. The quotient of the width of the epiglottis and the perpendicular from a fixed point on the dorsal pharynx to the epiglottis could be used to determine the pharyngeal diameter. The percentage change of this quotient (pharynx-epiglottis-ratio; PE-ratio) in the unrestrained head-neck position against the reference position was significantly larger than that of any other combination of the head-neck positions investigated. A relation between the percentage change in PE-ratio and the degree of head and neck flexion could not be confirmed. Conclusions It could be shown, that the pharyngeal diameter is reduced through the contact position implemented by the rider in comparison to the unrestrained head and neck position. An alteration of the pharyngeal diameter depending on the degree of head and neck flexion (represented by ground and withers angle) could not be confirmed. PMID:24886465

2016-01-01

A growing concern in patients affected by Alzheimer's disease (AD) is dysphagia, or swallowing impairment, which leads to malnutrition, dehydration, weight loss, functional decline and fear of eating and drinking, as well as a decrease in the quality of life. Thus the diagnostic assessment of dysphagia in patients with AD is imperative to ensure that they receive effective management, avoiding complications, and reducing comorbidity and mortality in such a growing population. Dysphagia management requires a multidisciplinary approach considering that no single strategy is appropriate for all patients. However, evidence for clinical diagnostic assessment, interventions, and medical management of dysphagia in these patients are still limited: few studies are reporting the evaluation and the management among this group of patients. Here we analyzed the most recent findings in diagnostic assessment and management of swallowing impairment in patients affected by AD.

Background Esophageal dysphagia is common in gastroenterology practice and has multiple etiologies. A complication for some patients with dysphagia is food impaction. A valid and reliable questionnaire to rapidly evaluate esophageal dysphagia and impaction symptoms can aid the gastroenterologist in gathering information to inform treatment approach and further evaluation, including endoscopy. Methods 1,638 patients participated over two study phases. 744 participants completed the Brief Esophageal Dysphagia Questionnaire (BEDQ) for phase 1; 869 completed the BEDQ, Visceral Sensitivity Index, Gastroesophageal Reflux Disease Questionnaire, and Hospital Anxiety and Depression Scale for phase 2. Demographic and clinical data were obtained via the electronic medical record. The BEDQ was evaluated for internal consistency, split-half reliability, ceiling and floor effects, and construct validity. Key Results The BEDQ demonstrated excellent internal consistency, reliability, and construct validity. The symptom frequency and severity scales scored above the standard acceptable cutoffs for reliability while the impaction subscale yielded poor internal consistency and split-half reliability; thus the impaction items were deemed qualifiers only and removed from the total score. No significant ceiling or floor effects were found with the exception of 1 item, and inter-item correlations fell within accepted ranges. Construct validity was supported by moderate yet significant correlations with other measures. The predictive ability of the BEDQ was small but significant. Conclusions & Inferences The BEDQ represents a rapid, reliable and valid assessment tool for esophageal dysphagia with food impaction for clinical practice that differentiates between patients with major motor dysfunction and mechanical obstruction.

Screening assessments for dysphagia are essential in neurodegenerative disease. Yet there are no purpose-built tools to quantify swallowing deficits at bedside or in clinical trials. A quantifiable, brief, easy to administer assessment that measures the impact of dysphagia and predicts the presence or absence of aspiration is needed. The Clinical Assessment of Dysphagia in Neurodegeneration (CADN) was designed by a multidisciplinary team (neurology, neuropsychology, speech pathology) validated against strict methodological criteria in two neurodegenerative diseases, Parkinson's disease (PD) and degenerative ataxia (DA). CADN comprises two parts, an anamnesis (part one) and consumption (part two). Two-thirds of patients were assessed using reference tests, the SWAL-QOL symptoms subscale (part one) and videofluoroscopic assessment of swallowing (part two). CADN has 11 items and can be administered and scored in an average of 7 min. Test-retest reliability was established using correlation and Bland-Altman plots. 125 patients with a neurodegenerative disease were recruited; 60 PD and 65 DA. Validity was established using ROC graphs and correlations. CADN has sensitivity of 79 and 84% and specificity 71 and 69% for parts one and two, respectively. Significant correlations with disease severity were also observed (p < 0.001) for PD with small to large associations between disease severity and CADN scores for DA. Cutoff scores were identified that signal the presence of clinically meaningful dysphagia symptomatology and risk of aspiration. The CADN is a reliable, valid, brief, quantifiable, and easily deployed assessment of swallowing in neurodegenerative disease. It is thus ideally suited for both clinical bedside assessment and future multicentre clinical trials in neurodegenerative disease.

2015-09-01

Pharyngitis is a common presentation, but it can also be associated with life-threatening processes, including sepsis and airway compromise. Other conditions, such as thyroid disease and cardiac disease, may mimic pharyngitis. The emergency clinician must sort through the broad differential for this complaint using a systematic approach that protects against early closure of the diagnosis. This issue reviews the various international guidelines for pharyngitis and notes controversies in diagnostic and treatment strategies, specifically for management of suspected bacterial, viral, and fungal etiology. A management algorithm is presented, with recommendations based on a review of the best available evidence, taking into account patient comfort and outcomes, the need to reduce bacterial resistance, and costs.

A retrospective case-control study. The aim of this study was to determine the effect of retropharyngeal steroids on postoperative dysphagia scores and clinical outcomes following multilevel anterior cervical discectomy and fusion (ACDF). Dysphagia is a well-known complication following ACDF surgery and increased rates of dysphagia are seen with increased levels of surgery. Retropharyngeal steroids have been shown to decrease painful swallowing and prevertebral soft tissue (PSTS) swelling in 1- and 2-level anterior cervical surgery. A retrospective review of 44 patients undergoing multilevel (2-, 3-, 4-level) ACDF. Twenty-two patients who received retropharyngeal steroids (methylprednisone) placed on a collagen sponge at the time of surgery were compared with a matched cohort of controls who did not receive local steroids. Postoperative day 1 and 6-week radiographs were analyzed for differences in PSTS. Clinical outcomes were measured pre-operatively, 6 weeks, and 3 months postoperatively utilizing the Neck Disability Index (NDI), the Bazaz-Yoo Dysphagia Scoring System, and Eat Assessment Tool (EAT-10). Significant improvement in dysphagia scores were seen utilizing both outcome measures. Bazaz-Yoo scores were significantly better at both 6 weeks and 3 months in patients receiving local steroids compared with controls (P = 0.008 and P = 0.022, respectively). EAT-10 showed similar improvement of the steroid group versus control at 6 weeks and 3 months (P = 0.067 and P = 0.012, respectively). A trend toward decreased PSTS was found with locally delivered steroids on initial postoperative radiographs (P = 0.07), but was no longer evident at 6 weeks. NDI, although improved from pre-operative scores, failed to demonstrate significant differences between groups. No differences in length of stay or complications were observed between the groups. The use of retropharyngeal steroids resulted in decreased rates of dysphagia following multilevel ACDF

The main objective of this study was to understand the relationship between oropharyngeal dysphagia, nutritional risk factors and functional impairment in the elderly (>65y) admitted to a medical-surgical hospital unit. Secondary objectives were to determine the prevalence of oropharyngeal dysphagia, the nutritional status and their functional capacity. A cross-sectional observational study was performed. It included patients over 65 years of age admitted to the Gastroenterology-Urology Department in La Princesa University Hospital (Madrid, Spain) during the months of February and March. The following variables were recorded: age, sex, body mass index, family support, diagnosis, comorbidity, oropharyngeal dysphagia (EAT-10 and volume-viscosity evaluation method), malnutrition (Mininutritional Assessment) and functional capacity (Barthel index). A total of 167 patients were recruited, with 30.8% and 15.4% prevalence of dysphagia and malnutrition, respectively. Prevalence of malnutrition increased to 75% in patients with oropharyngeal dysphagia. The logistic regression analysis showed how conditions as low score on the Barthel index (OR 0.97 [95% CI, 0.95-0.99]), comorbidity (OR 7.98 [CI 95%, 3.09-20.61]) and dysphagia (OR 4.07 [CI 95%, 1.57-10.52]) were associated with a greater likelihood of suffering malnutrition. Oropharyngeal dysphagia is one of the most underdiagnosed and underestimated conditions among elderly patients and one that has a greater effect on their nutritional status. Accordingly, we suggest using established diagnostic methods with a multidisciplinary team collaboration for its early detection. Copyright © 2013 Elsevier España, S.L. All rights reserved.

Dysphagia can have severe consequences for the patient's health, influencing health-related quality of life (HRQoL). Sound psychometric properties of HRQoL questionnaires are a precondition for assessing the impact of dysphagia, the focus of this study, resulting in recommendations for the appropriate use of these questionnaires in both clinical practice and research contexts. We performed a systematic review starting with a search for and retrieval of all full-text articles on the development of HRQoL questionnaires related to oropharyngeal dysphagia and/or their psychometric validation from the electronic databases PubMed and Embase published up to June 2011. Psychometric properties were judged according to quality criteria proposed for health status questionnaires. Eight questionnaires were included in this study. Four are aimed solely at HRQoL in oropharyngeal dysphagia: the deglutition handicap index (DHI), dysphagia handicap index (DHI'), M.D. Anderson Dysphagia Inventory (MDADI), and SWAL-QOL, while the EDGQ, EORTC QLQ-STO 22, EORTC QLQ-OG 25 and EORTC QLQ-H&N35 focus on other primary diseases resulting in dysphagia. The psychometric properties of the DHI, DHI', MDADI, and SWAL-QOL were evaluated. For appropriate applicability of HRQoL questionnaires, strong scores on the psychometric criteria face validity, criterion validity, and interpretability are prerequisites. The SWAL-QOL has the strongest ratings for these criteria, while the DHI' is the most easy to apply given its 25 items and the use of a uniform scoring format. For optimal use of HRQoL questionnaires in diverse settings, it is necessary to combine psychometric and utility approaches.

We aimed in this study to evaluate dysphagia in early stroke patients using a bedside screening test and flexible fiberoptic endoscopic evaluation of swallowing (FFEES) and electrophysiological evaluation (EE) methods and to compare the effectiveness of these methods. Twenty-four patients who were hospitalized in our clinic within the first 3 months after stroke were included in this study. Patients were evaluated using a bedside screening test [including bedside dysphagia score (BDS), neurological examination dysphagia score (NEDS), and total dysphagia score (TDS)] and FFEES and EE methods. Patients were divided into normal-swallowing and dysphagia groups according to the results of the evaluation methods. Patients with dysphagia as determined by any of these methods were compared to the patients with normal swallowing based on the results of the other two methods. Based on the results of our study, a high BDS was positively correlated with dysphagia identified by FFEES and EE methods. Moreover, the FFEES and EE methods were positively correlated. There was no significant correlation between NEDS and TDS levels and either EE or FFEES method. Bedside screening tests should be used mainly as an initial screening test; then FFEES and EE methods should be combined in patients who show risks. This diagnostic algorithm may provide a practical and fast solution for selected stroke patients.

To conduct a systematic review to determine whether clinical findings can be used to rule in or to rule out streptococcal pharyngitis in children. Two authors independently searched MEDLINE and EMBASE. We included articles if they contained data on the accuracy of symptoms or signs of streptococcal pharyngitis, individually or combined into prediction rules, in children 3-18 years of age. Thirty-eight articles with data on individual symptoms and signs and 15 articles with data on prediction rules met all inclusion criteria. In children with sore throat, the presence of a scarlatiniform rash (likelihood ratio [LR], 3.91; 95% CI, 2.00-7.62), palatal petechiae (LR, 2.69; CI, 1.92-3.77), pharyngeal exudates (LR, 1.85; CI, 1.58-2.16), vomiting (LR, 1.79; CI, 1.58-2.16), and tender cervical nodes (LR, 1.72; CI, 1.54-1.93) were moderately useful in identifying those with streptococcal pharyngitis. Nevertheless, no individual symptoms or signs were effective in ruling in or ruling out streptococcal pharyngitis. Symptoms and signs, either individually or combined into prediction rules, cannot be used to definitively diagnose or rule out streptococcal pharyngitis. Copyright © 2012 Mosby, Inc.

Although oropharyngeal candidiasis is associated with inhaled corticosteroid (ICS) usage, there is sparse data on the prevalence of posterior pharyngeal candidiasis in those without any detectable oral candidiasis on clinical examination. We systematically investigated the relationship between oral candidiasis on clinical examination and the presence of posterior pharyngeal candidiasis at bronchoscopy. We conducted a cross-sectional study on a convenience sample of 100 patients undergoing bronchoscopy at our institution. Patients were assessed for symptoms of and risk factors for candida infection and had an examination of their oropharynx for evidence of candidiasis before bronchoscopy. They subsequently had a detailed assessment for posterior candidiasis at bronchoscopy. We performed a posteriori subgroup analysis, which focused solely on those patients on ICS maintenance therapy. Median age was 54.7 (27-84) years, and 55 patients were male; 47 % of patients were on ICS, and 20 % of this cohort received recent oral corticosteroids. Twenty-eight percent of this convenience sample had posterior pharyngeal candidiasis; however, only 10.7 % (3/28) of these patients had clinically detectable oral candidiasis on clinical examination before bronchoscopy. Factors that were independently associated with the presence of pharyngeal candidiasis at bronchoscopy were OR (95 % CI) ICS usage 6.9 (2.5-19.2), particularly fluticasone usage 6.8 (2.62-17.9) and the presence of dysphonia 3.2 (1.3-8.0). In the subgroup analysis of ICS usage, posterior pharyngeal candidiasis was correlated with the presence of dysphonia but was not independently associated with fluticasone or budesonide dosage. This study demonstrates that posterior pharyngeal candidiasis in the absence of clinically overt oral candidiasis is frequent amongst ICS users. A history of ICS use, particularly fluticasone usage, as well as the presence of dysphonia are associated with posterior pharyngeal candidiasis at

The recurrent laryngeal nerve is at risk of injury during open pharyngeal diverticula operations. The utility of recurrent laryngeal nerve (RLN) monitoring during these procedures was investigated. A retrospective chart review was performed of 8 open pharyngeal diverticulectomies completed between 2009 and 2014. Intraoperative RLN monitoring took place during all operations. Open pharyngectomy and myotomy was successfully performed in all cases. In two cases the RLN was encountered outside of its normal course. The identity of the nerve was confirmed with electrical stimulation and normal EMG response. Vocal fold motion was preserved in all cases. Use of intraoperative nerve monitoring in pharyngeal diverticula procedures may be beneficial, especially during open operations for Killian-Jamieson diverticulum (KJD) and large Zenker diverticulum (ZD), where the RLN is typically encountered outside of its normal course. © The Author(s) 2016.

To investigate the causes of refractory pharyngeal paraesthesia. Besides routine examination of otolaryngology, 600 patients were tested by fiberoptic laryngoscopy, fiberoptic gastroesophagoscopy, nasal sinuses CT, styloid process X-ray as well as neck and thyroid gland B ultrasonography. Then, they were treated according to respective causes. Among 600 cases of refractory pharyngeal paraesthesia, 229 (38.2%) cases were diagnosed as gastroesophagitis, 113 (18.8%) nasal sinusitis, 57 (9.5%) climacteric syndromes, 40 (6.7%) chronic tonsillitis, 22 (3.7%) carcinophobia, 13 (2.2%) subacute thyroiditis or thyrophymas, 9 (1.5%) elongation of styloid process and 117 (19.5%) other causes. All patients were treated according to respective causes and total cure rate was 84.2% after 6 months. There are many causes of pharyngeal paraesthesia. We should pay attention to its relationship with gastroesophagitis and nasal sinusitis etc, especially, gastroesophageal reflux disease.

To evaluate the risks of medical conditions, evaluate gastric sleeve narrowing, and assess hydrostatic balloon dilatation to treat dysphagia after vertical sleeve gastrectomy (VSG). VSG is being performed more frequently worldwide as a treatment for medically-complicated obesity, and dysphagia is common post-operatively. We hypothesize that post-operative dysphagia is related to underlying medical conditions or narrowing of the gastric sleeve. This is a retrospective, single institution study of consecutive patients who underwent sleeve gastrectomy from 2013 to 2015. Patients with previous bariatric procedures were excluded. Narrowing of a gastric sleeve includes: inability to pass a 9.6 mm gastroscope due to stenosis or sharp angulation or spiral hindering its passage. Of 400 consecutive patients, 352 are included; the prevalence of dysphagia is 22.7%; 33 patients (9.3%) have narrowing of the sleeve with 25 (7.1%) having sharp angulation or a spiral while 8 (2.3%) have a stenosis. All 33 patients underwent balloon dilatation of the gastric sleeve and dysphagia resolved in 13 patients (39%); 10 patients (30%) noted resolution of dysphagia after two additional dilatations. In a multivariate model, medical conditions associated with post-operative dysphagia include diabetes mellitus, symptoms of esophageal reflux, a low whole blood thiamine level, hypothyroidism, use of non-steroidal anti-inflammatory drugs, and use of opioids. Narrowing of the gastric sleeve and gastric sleeve stenosis are common after VSG. Endoscopic balloon dilatations of the gastric sleeve resolves dysphagia in 69% of patients.

Despite the remarkable burden of dysphagia, appropriate multidisciplinary management is lacking in Iran and patients are often deprived of effective treatments. Obtaining a full understanding of knowledge, attitude and practice (KAP) of healthcare providers is necessary to determine the gaps in improvement of the quality of care for dysphagic patients. A questionnaire was designed covering demographic information and the parameters of KAP. Face and content validity were determined. Test-retest reliability confirmed that the questionnaire scores are stable over time (r = 0.77, p value < 0.01). Participants were healthcare providers employed in university-affiliated hospitals in three major cities of Iran; Tehran, Shiraz and Mashhad. In total, 312 healthcare professionals completed our survey. The majority (96.8%) were familiar with the term "dysphagia or swallowing disorders". Most of the participants believed their profession (88.5%), as well as other disciplines (92.3%) can play an important role in the management of dysphagia; and this problem should be recognized in a multidisciplinary manner (96.2%). Also, 60.9% had encountered a patient with dysphagia. 52.2% had used at least one assessment method, while 49.9% had applied at least one treatment method. However, very few participants were familiar with a standard test for screening and assessment of dysphagia (11.9%). 74.7% were willing to participate in a workshop on dysphagia. As the main pitfalls of care lie in diagnosis and treatment expertise, the policy of hospitals should prioritize educating and updating the skills of healthcare professionals, encourage multidisciplinary teamwork, establishing clear guidelines and facilitate access to advanced tools.

Improvement of dysphagia in a child affected by Pompe disease treated with enzyme replacement therapy

PubMed Central

2013-01-01

Aim Dysphagia is a known complication in Pompe Disease (PD), a severe metabolic myopathy due to alpha-glucosidase deficiency. Enzyme replacement therapy (ERT) with alglucosidase alfa is the only approved therapy for PD. Presently no data are available on the effects of ERT on dysphagia in PD patients. The aim of this work is to evaluate the course of this complication in a 6 years old boy affected by PD after treatment with ERT. Methods Dysphagia was assessed by Videofluoroscopic Swallowing Study (VFSS) at baseline, before the start of ERT and after 36 months of therapy. We used the Dysphagia Severity Rating Scale (DSS) to define the severity grade of dysphagia. Results VFSS performed at baseline revealed complete incoordination of oral stage swallowing which was classified as a grade 1 dysphagia according to DSS. After 36 months of treatment VFSS revealed normal swallowing, classified as grade 0 by DSS. Conclusion Our results suggest that ERT is effective in improving dysphagia. VFSS may be a useful tool to investigate and monitor swallowing disorders in patients affected by PD. PMID:23668440

Background The aim of this study was to compare spontaneous swallow frequency analysis (SFA) with clinical screening protocols for identification of dysphagia in acute stroke. Methods In all, 62 patients with acute stroke were evaluated for spontaneous swallow frequency rates using a validated acoustic analysis technique. Independent of SFA, these same patients received a routine nurse-administered clinical dysphagia screening as part of standard stroke care. Both screening tools were compared against a validated clinical assessment of dysphagia for acute stroke. In addition, psychometric properties of SFA were compared against published, validated clinical screening protocols. Results Spontaneous SFA differentiates patients with versus without dysphagia after acute stroke. Using a previously identified cut point based on swallows per minute, spontaneous SFA demonstrated superior ability to identify dysphagia cases compared with a nurse-administered clinical screening tool. In addition, spontaneous SFA demonstrated equal or superior psychometric properties to 4 validated, published clinical dysphagia screening tools. Conclusions Spontaneous SFA has high potential to identify dysphagia in acute stroke with psychometric properties equal or superior to clinical screening protocols. PMID:25088166

A long-term cineradiographic follow-up study of twenty patients with velo-pharyngeal incompetence fails to demonstrate predictable retrodisplacement of the levator insertion following combined levator retropositioning, pushback, and pharyngeal flap procedures. Simple levator retropositioning gave posterior displacement in the two patients evaluated. Patients with normal or posterior levator insertions pre-operatively all demonstrated post-operative anterior displacement following pharyngeal flap procedures, either alone or in combination with pushback. Anterior levator displacement may be the result of scar contraction or division of the levator sling (during insetting of a pharyngeal flap). Pre-operative and post-operative speech evaluation demonstrated substantial improvement in all except 3 patients; 2 of the poor speech results were patients with demonstrated levator retrodisplacement on post-operative cineradiography.

Patient-reported outcome (PRO) measures are commonly used to capture patient experience with dysphagia and to evaluate treatment effectiveness. Inappropriate application can lead to distorted results in clinical studies. A systematic review of the literature on dysphagia-related PRO measures was performed to (1) identify all currently available measures and (2) to evaluate each for the presence of important measurement properties that would affect their applicability. MEDLINE via the PubMed interface, the Cumulative Index of Nursing and Allied Health Literature, and the Health and Psychosocial Instrument database were searched using relevant vocabulary terms and key terms related to PRO measures and dysphagia. Three independent investigators performed abstract and full text reviews. Each study meeting criteria was evaluated using an 18-item checklist developed a priori that assessed multiple domains: (1) conceptual model, (2) content validity, (3) reliability, (4) construct validity, (6) scoring and interpretation, and (7) burden and presentation. Of 4950 abstracts reviewed, a total of 34 dysphagia-related PRO measures (publication year 1987-2014) met criteria for extraction and analysis. Several PRO measures were of high quality (MADS for achalasia, SWAL-QOL and SSQ for oropharyngeal dysphagia, PROMIS-GI for general dysphagia, EORTC-QLQ-OG25 for esophageal cancer, ROMP-swallowing for Parkinson's Disease, DSQ-EoE for eosinophilic esophagitis, and SOAL for total laryngectomy-related dysphagia). In all, 17 met at least one criterion per domain. Thematic deficiencies in current measures were evident including: (1) direct patient involvement in content development, (2) empirically justified dimensionality, (3) demonstrable responsiveness to change, (4) plan for interpreting missing responses, and (5) literacy level assessment. This is the first comprehensive systematic review assessing developmental properties of all available dysphagia-related PRO measures. We

Post-stroke dysphagia (a difficulty in swallowing after a stroke) is a common and expensive complication of acute stroke and is associated with increased mortality, morbidity, and institutionalization due in part to aspiration, pneumonia, and malnutrition. Although most patients recover swallowing spontaneously, a significant minority still have dysphagia at six months. Although multiple advances have been made in the hyperacute treatment of stroke and secondary prevention, the management of dysphagia post-stroke remains a neglected area of research, and its optimal management, including diagnosis, investigation and treatment, have still to be defined. © 2016 World Stroke Organization.

The prevalence and severity of dysphagia in people treated non-surgically for primary head and neck cancer (HNC) is well documented. However, few studies have looked beyond the physiological impairment to explore the lived experience of dysphagia in the post-treatment period of HNC. The current study adopted a person-centred, qualitative approach to describe the experiences of people living with dysphagia in the months and years following non-surgical treatment for HNC. Using maximum variation sampling, 24 participants who had undergone radiotherapy treatment for HNC were recruited. Individual interviews were conducted to explore the impact of dysphagia on participants' everyday lives. The themes identified included: (1) physical changes related to swallowing; (2) emotions evoked by living with dysphagia; (3) altered perceptions and changes in appreciation of food; and (4) personal and lifestyle impacts. The data revealed the breadth and significance of the impact of dysphagia on the lives of people treated curatively for HNC. Assessment and management in the post-treatment period must be sufficiently holistic to address both the changing physical states and the psychosocial needs of people with dysphagia following HNC. Rehabilitation services which focus only on impairment-based management will fail to fully meet the support needs of this clinical population.

Dysphagia in Children with Esophageal Atresia: Current Diagnostic Options.

2015-08-01

Dysphagia or swallowing disorder is very common (range, 15-52%) in patients with esophageal atresia. Children present with a wide range of symptoms. The most common diagnostic tools to evaluate esophageal dysphagia, such as upper barium study and manometry, aim to characterize anatomy and function of the esophageal body and the esophagogastric junction (EGJ). Using these technologies, a variety of pathological motor patterns have been identified in children with esophageal atresia. However, the most challenging part of diagnosing patients with esophageal dysphagia lies in the fact that these methods fail to link functional symptoms such as dysphagia with the esophageal motor disorders observed. A recent method, called pressure-flow analysis (PFA), uses simultaneously acquired impedance and manometry measurements, and applies an integrated analysis of these recordings to derive quantitative pressure-flow metrics. These pressure-flow metrics allow detection of the interplay between bolus flow, motor patterns, and symptomatology by combining data on bolus transit and bolus flow resistance. Based on a dichotomous categorization, flow resistance at the EGJ and ineffective esophageal bolus transit can be determined. This method has the potential to guide therapeutic decisions for esophageal dysmotility in pediatric patients with esophageal atresia. Georg Thieme Verlag KG Stuttgart · New York.

Does velopharyngeal closure pattern affect the success of pharyngeal flap pharyngoplasty?

2005-01-01

Historically at The Hospital for Sick Children in Toronto, pharyngeal flap pharyngoplasty has been the treatment of choice for treatment of velopharyngeal insufficiency, regardless of velopharyngeal closure pattern. The authors hypothesize that pharyngeal flap pharyngoplasty is more effective in treating velopharyngeal insufficiency in patients with circular or sagittal velopharyngeal closure and less effective in treating the coronal closure pattern. Ninety-three patients who underwent superiorly based pharyngeal flap surgery for velopharyngeal insufficiency were evaluated in a retrospective chart review. Closure pattern was determined preoperatively by nasopharyngoscopy or multiview videofluoroscopy. Nasalance was assessed preoperatively and at 6 weeks and 1 year postoperatively. Nasalance during nonnasal speech was decreased on average, for all closure patterns, postoperatively. However, a significantly higher percentage of patients were corrected to normal nasalance scores in thenoncoronal group than in the coronal group (57 percent versus 35 percent, respectively) at 1 year postoperatively (p < 0.05). Surgical overcorrection, as determined by postoperative hyponasality, occurred at a rate of 13 percent in the coronal group versus 7 percent in the noncoronal group (not statistically significant). The results demonstrate that hypernasality in patients with a coronal velopharyngeal closure pattern can be improved by pharyngeal flap pharyngoplasty. This procedure, however, is more frequently effective in correcting noncoronal closure pattern velopharyngeal insufficiency than coronal pattern velopharyngeal insufficiency. The authors are now more selective in their approach to the management of velopharyngeal insufficiency and are more inclined to treat coronal pattern velopharyngeal insufficiency with sphincter pharyngoplasty.

INTRODUCTION Fundoplication for laryngopharyngeal disease with oesophageal dysmotility has led to mixed outcomes. In the presence of preoperative dysphagia and oesophageal dysmotility, this procedure has engendered concern in certain regards. METHODS This paper describes a consecutive series of laryngopharyngeal reflux (LPR) patients with a high frequency of dysmotility. Patients were selected for surgery with 24-hour dual channel pH monitoring, oesophageal manometry and standardised reflux scintigraphy. RESULTS Following careful patient selection, 33 patients underwent fundoplication by laparoscopy. Surgery had high efficacy in symptom control and there was no adverse dysphagia. CONCLUSIONS Evidence of proximal reflux can select a group of patients for good results of fundoplication for atypical symptoms.

The aim of this case study was to verify the occurrence of dysphagia in acute ischemic stroke within 48 hours after the onset of the first symptoms, in order to establish a possible relationship between the level of neurologic impairment and the severity degree of dysphagia. After emergency hospital admission, three patients underwent neurological clinical evaluation (general physical examination, neurological examination, and application of the National Institute of Health Stroke Scale - NIHSS), and clinical assessment of swallowing using the Protocolo Fonoaudiológico de Avaliação do Risco para Disfagia (PARD--Speech-Language Pathology Protocol for Risk Evaluation for Dysphagia). One of the patients presented functional swallowing (NIHSS score 11), while the other two had mild and moderate oropharyngeal dysphagia (NIHSS scores 15 and 19, respectively). The service flow and the delay on the patients' search for medical care determined the small sample. The findings corroborate literature data regarding the severity of the neurological condition and the manifestation of dysphagia.

Patients with non-metastatic esophageal cancer routinely undergo endoscopic ultrasound (EUS) for loco-regional staging. Neoadjuvant therapy is recommended for ≥T3 tumors while upfront surgery can be considered for ≤T2 lesions. The aim of this study was to determine if the degree of dysphagia can predict the EUS T-stage of esophageal cancer. One hundred eleven consecutive patients with non-metastatic esophageal cancer were retrospectively reviewed from a database. Prior to EUS, patients' dysphagia grade was recorded. Correlation between dysphagia grade and EUS T-stage, especially in reference to predicting ≥T3 stage, was determined. The correlation of dysphagia grade with EUS T-stage (Kendall's tau coefficient) was 0.49 (P < 0.001) for the lower and 0.59 (P = 0.008) for the middle esophagus. The sensitivity and specificity of dysphagia grade ≥2 (can only swallow semi-solids/liquids) for T3 cancer were 56% (95% confidence interval [CI] 43-67%) and 93% (95% CI 79-98%), respectively. The sensitivity, specificity, and positive predictive value of dysphagia grade ≥3 (can only swallow liquids or total dysphagia) for T3 lesions were 36% (95% CI 25-48%), 100% (95% CI 89-100%), and 100% (95% CI 83-100%), respectively. Overall, there was a significant positive correlation between dysphagia grade and the EUS T-stage of esophageal cancer. All patients with dysphagia grade ≥3 had T3 lesions. This may have clinical implications for patients who can only swallow liquids or have complete dysphagia by allowing for prompt initiation of neoadjuvant therapy, especially in countries/centers where EUS service is difficult to access in a timely manner or not available. © 2015 International Society for Diseases of the Esophagus.

Rapid evaluation of dysphagia poststroke significantly lowers rates of aspiration pneumonia. Logistical barriers often significantly delay in-person dysphagia evaluation by speech language pathologists (SLPs) in remote and rural hospitals. Clinical swallow evaluations delivered via telehealth have been validated in a number of clinical contexts, yet no one has specifically validated a teleswallow evaluation for in-hospital post-stroke dysphagia assessment. A team of 6 SLPs experienced in stroke care and a telestroke neurologist designed, implemented, and tested a teleswallow evaluation for acute stroke patients, in which 100 patients across 2 affiliated, urban certified stroke centers were sequentially evaluated by a bedside and telehealth SLP. Inter-rater reliability was analyzed using percent agreement, Cohen's kappa, Kendall's tau-b, and Wilcoxon matched-pairs signed rank tests. Logistic regression models accounting for age and gender were used to test the impact of stroke severity and stroke location on agreement. We found excellent agreement for both liquid (91% agreement; kappa = 0.808; Kendall's tau-b = 0.813, p < 0.001; Wilcoxon signed rank = -0.818, p = 0.417) and solid (87% agreement; kappa = 0.792; Kendall's tau-b = 0.844, p < 0.001; Wilcoxon signed rank = 0.243, p = 0.808) dietary textures. From regression modeling, there is suggestive but inconclusive evidence that higher National Institute of Health Stroke Scale (NIHSS) scores correlate with lower levels of agreement for liquid diet recommendations (OR [95% CI] 0.895 [0.793-1.01]; p = 0.07). There was no impact of NIHSS score for solid diet recommendations and no impact of stroke location on solid or liquid diet recommendations. Qualitatively, we identified professional, logistical, technical, and patient barriers to implementation, many of which resolved with experience over time. Dysphagia evaluation by a remote SLP via telehealth is safe and effective following stroke. We plan to implement

AIM To evaluate the risks of medical conditions, evaluate gastric sleeve narrowing, and assess hydrostatic balloon dilatation to treat dysphagia after vertical sleeve gastrectomy (VSG). METHODS VSG is being performed more frequently worldwide as a treatment for medically-complicated obesity, and dysphagia is common post-operatively. We hypothesize that post-operative dysphagia is related to underlying medical conditions or narrowing of the gastric sleeve. This is a retrospective, single institution study of consecutive patients who underwent sleeve gastrectomy from 2013 to 2015. Patients with previous bariatric procedures were excluded. Narrowing of a gastric sleeve includes: inability to pass a 9.6 mm gastroscope due to stenosis or sharp angulation or spiral hindering its passage. RESULTS Of 400 consecutive patients, 352 are included; the prevalence of dysphagia is 22.7%; 33 patients (9.3%) have narrowing of the sleeve with 25 (7.1%) having sharp angulation or a spiral while 8 (2.3%) have a stenosis. All 33 patients underwent balloon dilatation of the gastric sleeve and dysphagia resolved in 13 patients (39%); 10 patients (30%) noted resolution of dysphagia after two additional dilatations. In a multivariate model, medical conditions associated with post-operative dysphagia include diabetes mellitus, symptoms of esophageal reflux, a low whole blood thiamine level, hypothyroidism, use of non-steroidal anti-inflammatory drugs, and use of opioids. CONCLUSION Narrowing of the gastric sleeve and gastric sleeve stenosis are common after VSG. Endoscopic balloon dilatations of the gastric sleeve resolves dysphagia in 69% of patients. PMID:28058017

This study compared the immediate impact of different transcutaneous electrical stimulation (TES) amplitudes on physiological swallowing effort in healthy older adults versus young adults. Swallowing physiology changes with age. Reduced physiological swallowing effort in older adults including lower lingua-palatal and pharyngeal pressures may increase risk for swallowing dysfunction (i.e. dysphagia). Transcutaneous electrical stimulation (TES) has been advocated as an adjunctive modality to enhance outcomes in exercise-based therapy for individuals with dysphagia. However, significant variation in how TES is applied during therapy remains and the physiological swallowing response to TES is poorly studied, especially in older adults. Physiological change in swallowing associated with no stimulation, sensory stimulation and motor stimulation was compared in 20 young adults versus 14 older adults. Lingua-palatal and pharyngeal manometric pressures assessed physiological swallowing effort. Multivariate analyses identified interactions between age and stimulation amplitude on lingual and pharyngeal functions. Motor stimulation reduced anterior tongue pressure in both age groups but selectively reduced posterior lingua-palatal pressures in young adults only. Sensory stimulation increased base of tongue (BOT) pressures in older adults but decreased BOT pressures in young adults. Motor stimulation increased hypopharyngeal pressures in both groups. Age and TES level interact in determining immediate physiological responses on swallow performance. A one-size-fit-all approach to TES in dysphagia rehabilitation may be misdirected. © 2014 John Wiley & Sons A/S and The Gerodontology Association. Published by John Wiley & Sons Ltd.

[Significance of pharyngeal biochemical indexes in the diagnosis of laryngopharyngeal reflux disease].

Objective: To investigate the significance of the detection of pepsin in saliva and the pharyngeal pH monitoring in the diagnosis of laryngopharyngeal reflux disease(LPRD). Methods: A total of 176 patients (140 patients with simple pharyngitis and 36 patients with space-occupying lesions of larynx) who were suspected to have laryngopharyngeal reflux between February and December 2016 were retrospectively reviewed. All the patients were evaluated with reflux symptom index (RSI), reflux finding score (RFS) and 24-hour pharyngeal pH monitoring(Dx-pH). Saliva of patients was collected and the pepsin in the saliva was measured by enzyme-linked immunosorbent assay (ELISA). Results: The positive rate of RSI (RSI>13) and/or RFS (RFS>7) was 56.8% (100/176). The positive rate of pepsin in saliva was 40.9% (72/176) and pepsin in saliva collected at the time of onset of symptom was much higher than that at other time points ( P <0.001). The positive rate of pepsin in saliva, Ryan score and the pH<6.0 laryngopharyngeal reflux in space-occupying lesions group [55.6%(20/36), 27.8% (10/36), 69.4%(25/36), respectively] were all higher than simple pharyngitis group [37.1% (52/140), 5.0% (7/140), 50% (70/140), respectively] ( P =0.045, P <0.001, P =0.037, respectively). Conclusions: The detection of pepsin in saliva and the pharyngeal pH monitoring reflected different reflux agents, and there was great significance for the diagnosis of LPRD by using two methods together. We found that the weak acid state and consequent pepsin damage played an important role in the occurrence and development of space-occupying lesions of larynx.

With wide application of antireflux surgery, reoperations for failed fundoplications are increasingly seen. This study was undertaken to document outcomes after reoperative fundoplications. Sixty-four patients, 26 men and 38 women, of average age 55 years+/-15.6 (SD), underwent reoperative antireflux surgery between 1992 and 2003. Fundoplication prior to reoperation had been undertaken via celiotomy in 27 and laparoscopically in 37. Both before and after reoperative antireflux surgery, patients scored their reflux and dysphagia on a Likert Scale (0 = none, 10 = continuous). Reoperation was undertaken because of dysphagia in 16 per cent, recurrent reflux in 52 per cent (median DeMeester Score 52), or both in 27 per cent. Failure leading to reoperation was due to hiatal failure in 28 per cent, wrap failure in 19 per cent, both in 33 per cent, and slipped Nissen fundoplication in 20 per cent. Laparoscopic reoperations were completed in 49 of 54 patients (91%); 15 had reoperations undertaken via celiotomy. Eighty-eight per cent of reoperations were Nissen fundoplications. With reoperation, Dysphagia Scores improved from 9.5+/-0.7 to 2.6+/-2.8, and Reflux Scores improved from 9.1+/-1.4 to 1.8+/-2.7. Seventy-nine per cent of patients with reflux prior to reoperation, 100 per cent with dysphagia, and 74 per cent with both noted excellent or good outcomes after reoperation. We conclude that failure after fundoplication occurs. Reoperations reduce the severity of dysphagia and reflux, thus salvaging excellent and good outcomes in most. Laparoscopic reoperations are generally possible. Reoperative fundoplications are effective treatment for dysphagia and recurrent gastroesophageal reflux, and their application is encouraged.

Obstructive sleep apnea (OSA) and dysphagia are common in acute stroke and are both associated with increased risk of complications and worse prognosis. The aims of the present study were (1) to evaluate the prevalence of OSA and dysphagia in patients with acute, first-ever, ischemic stroke; (2) to investigate their clinical correlates; and (3) to verify if these conditions are associated in acute ischemic stroke. We enrolled a cohort of 140 consecutive patients with acute-onset (<48 hours), first-ever ischemic stroke. Computed tomography (CT) and magnetic resonance imaging scans confirmed the diagnosis. Neurological deficit was measured using the National Institutes of Health Stroke Scale (NIHSS) by examiners trained and certified in the use of this scale. Patients underwent a clinical evaluation of dysphagia (Gugging Swallowing Screen) and a cardiorespiratory sleep study to evaluate the presence of OSA. There are 72 patients (51.4%) with obstructive sleep apnea (OSA+), and there are 81 patients (57.8%) with dysphagia (Dys+). OSA+ patients were significantly older (P = .046) and had greater body mass index (BMI) (P = .002), neck circumference (P = .001), presence of diabetes (P = .013), and hypertension (P < .001). Dys+ patients had greater NIHSS (P < .001), lower Alberta Stroke Programme Early CT Score (P < .001), with greater BMI (P = .030). The association of OSA and dysphagia was greater than that expected based on the prevalence of each condition in acute stroke (P < .001). OSA and dysphagia are associated in first-ever, acute ischemic stroke. Copyright © 2018 National Stroke Association. Published by Elsevier Inc. All rights reserved.

Dysphagia is a common symptom with diverse etiology in otolaryngology. In the present study clinicopathological, radiological and endoscopic evaluation of patients was done in a tertiary care hospital in patients presenting with dysphagia. A prospective nonrandomized observational study was carried out on total of 80 cases having dysphagia during March 2015 to August 2016. In the present study, out of 80 patients, youngest case was a three years old child while oldest case was an 85 years old female. The mean age was 48.3 ± 20.3 years. The majority of cases were in age group 41-59 years (35%). Male to female ratio was 2.33:1. The mean duration of illness was 15.44 weeks. 15% of patients had absolute dysphagia. For detecting the lesion, Barium swallow study (BSS) showed a total sensitivity of 49.05% (n = 53), Computerised Tomography (CT) showed a total sensitivity of 85.70% (n = 49), plain skiagram neck & chest showed a total sensitivity of 88.88% (n = 9) and endoscopy was the most sensitive test overall as it showed a total sensitivity of 98.75% (n = 80). No complications were reported with either rigid or flexible endoscopy. Dysphagia is a common presenting complaint in otolaryngology with cases coming directly or being referred from other specialities. Males are more commonly affected than females and incidence of malignancy increases with age. Endoscopy can become the first screening test in dysphagia due to its high sensitivity and low risk of complications, with radiological tests being done in an adjunct manner.
