    Dysphagia is a very frequent and highly relevant symptom in Parkinson's disease (PD) for quality of life, morbidity, and remaining lifetime, which is unfortunately widely underdiagnosed and underestimated regarding patients' centered care. Especially in early stages, the causal association between disease and swallowing disabilities remains unnoticed, which may be accounted for by the inability of caregivers and physicians to detect subtle swallowing problems and by the low self-awareness among PD patients. In order to prevent patients from serious negative consequences for health issues (e.g., aspiration pneumonia or malnutrition) as well as for negative impact on their quality of life, it is on the highest importance of managing dysphagia timely and working closely together in a multidisciplinary team, who all are involved in the patients' care system. This chapter includes background information on epidemiology, pathophysiology, and symptomatology of swallowing disorders in PD. This is followed by a summary of the clinical course and health treats, adequate diagnostic procedures for early identification of dysphagia as well as effective treatment strategies. The conclusion provides recommendations for clinical practice routine. © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Hyperglycaemia, fever, and swallowing dysfunction are poorly managed in the admission phase of acute stroke, and patient outcomes are compromised. Use of evidence-based guidelines could improve care but have not been effectively implemented. Our study aims to develop and trial an intervention based on multidisciplinary team-building to improve management of fever, hyperglycaemia, and swallowing dysfunction in patients following acute stroke. Methods and design Metropolitan acute stroke units (ASUs located in New South Wales, Australia will be stratified by service category (A or B and, within strata, by baseline patient recruitment numbers (high or low in this prospective, multicentre, single-blind, cluster randomised controlled trial (CRCT. ASUs then will be randomised independently to either intervention or control groups. ASUs allocated to the intervention group will receive: unit-based workshops to identify local barriers and enablers; a standardised core education program; evidence-based clinical treatment protocols; and ongoing engagement of local staff. Control group ASUs will receive only an abridged version of the National Clinical Guidelines for Acute Stroke Management. The following outcome measures will be collected at 90 days post-hospital admission: patient death, disability (modified Rankin Score; dependency (Barthel Index and Health Status (SF-36. Additional measures include: performance of swallowing screening within 24 hours of admission; glycaemic control and temperature control. Discussion This is a unique study of research transfer in acute stroke. Providing optimal inpatient care during the admission phase is essential if we are to combat the rising incidence of debilitating stroke. Our CRCT will also allow us to test interventions focussed on multidisciplinary ASU teams rather than individual disciplines, an imperative of modern hospital services.

    Fever, hyperglycemia, and swallow dysfunction poststroke are associated with significantly worse outcomes. We report treatment and monitoring practices for these three items from a cohort of acute stroke patients prior to randomization in the Quality in Acute Stroke Care trial. Retrospective medical record audits were undertaken for prospective patients from 19 stroke units. For the first three-days following stroke, we recorded all temperature readings and administration of paracetamol for fever (≥37·5°C) and all glucose readings and administration of insulin for hyperglycemia (>11 mmol/L). We also recorded swallow screening and assessment during the first 24 h of admission. Data for 718 (98%) patients were available; 138 (19%) had four hourly or more temperature readings and 204 patients (29%) had a fever, with 44 (22%) receiving paracetamol. A quarter of patients (n = 102/412, 25%) had six hourly or more glucose readings and 23% (95/412) had hyperglycemia, with 31% (29/95) of these treated with insulin. The majority of patients received a swallow assessment (n = 562, 78%) by a speech pathologist in the first instance rather than a swallow screen by a nonspeech pathologist (n = 156, 22%). Of those who passed a screen (n = 108 of 156, 69%), 68% (n = 73) were reassessed by a speech pathologist and 97% (n = 71) were reconfirmed to be able to swallow safely. Our results showed that acute stroke patients were: undermonitored and undertreated for fever and hyperglycemia; and underscreened for swallowing dysfunction and unnecessarily reassessed by a speech pathologist, indicating the need for urgent behavior change. © 2013 The Authors.

    Full Text Available Swallowing dysfunction can lead to recurring aspiration and is frequently associated with chronic symptoms such as cough and wheezing in infants. Our objective was to describe the characteristics of infants with swallowing dysfunction, determine if pulmonary function abnormalities are detectable, and if they improve after therapy.We studied 38 infants with a history of coughing and wheezing who had pulmonary function tests performed within two weeks of their diagnosis of swallowing dysfunction. The raised lung volume rapid thoracoabdominal compression technique was used. After 6 months of therapy, 17 of the infants repeated the tests.Initially, 25 had abnormal spirometry, 18 had abnormal plethysmography, and 15 demonstrated bronchodilator responsiveness. Six months later test were repeated for seventeen patients. Ten patients had continued abnormal spirometry, two patients remained normal, three patients' abnormal spirometry had normalized, and two patients' previously normal studies became abnormal. Eight of the 17 patients had continued abnormal plethysmography, six had continued normal plethysmography, and three patients' normal plethysmography became abnormal. After 6 months of treatment, eight patients demonstrated bronchodilator responsiveness, of which five continued to demonstrate bronchodilator responsiveness and three developed responsiveness. The remainder either continued to be non- bronchodilator responsive (two or lost responsiveness (three. The findings of the abnormal tests in most infants tested is complicated by frequent occurrence of other co-morbidities in this population, including gastroesophageal reflux in 23 and passive smoke exposure in 13 of the infants.The interpretation of lung function changes is complicated by the frequent association of swallowing dysfunction with gastroesophageal reflux and passive smoke exposure in this population.

    Full Text Available CONTEXT: Stroke is a frequent cause of dysphagia. OBJECTIVE: To evaluate in a tertiary care hospital the prevalence of swallowing dysfunction in stroke patients, to analyze factors associated with the dysfunction and to relate swallowing dysfunction to mortality 3 months after the stroke. METHODS: Clinical evaluation of deglutition was performed in 212 consecutive patients with a medical and radiologic diagnosis of stroke. The occurrence of death was determined 3 months after the stroke. RESULTS: It was observed that 63% of the patients had swallowing dysfunction. The variables gender and specific location of the lesion were not associated with the presence or absence of swallowing dysfunction. The patients with swallowing dysfunction had more frequently a previous stroke, had a stroke in the left hemisphere, motor and/or sensitivity alterations, difficulty in oral comprehension, alteration of oral expression, alteration of the level of consciousness, complications such as fever and pneumonia, high indexes on the Rankin scale, and low indexes on the Barthel scale. These patients had a higher mortality rate. CONCLUSIONS: Swallowing evaluation should be done in all patients with stroke, since swallowing dysfunction is associated with complications and an increased risk of death.

    Our randomized controlled trial of a multifaceted evidence-based intervention for improving the inpatient management of fever, hyperglycemia, and swallowing dysfunction in the first three-days following stroke improved outcomes at 90 days by 15%. We designed a quantitative process evaluation to further explain and illuminate this finding. Blinded retrospective medical record audits were undertaken for patients from 19 stroke units prior to and following the implementation of three multidisciplinary evidence-based protocols (supported by team-building workshops, and site-based education and support) for the management of fever (temperature ≥37·5°C), hyperglycemia (glucose >11 mmol/l), and swallowing dysfunction in intervention stroke units. Data from 1804 patients (718 preintervention; 1086 postintervention) showed that significantly more patients admitted to hospitals allocated to the intervention group received care according to the fever (n = 186 of 603, 31% vs. n = 74 of 483, 15%, P < 0·001), hyperglycemia (n = 22 of 603, 3·7% vs. n = 3 of 483, 0·6%, P = 0·01), and swallowing dysfunction protocols (n = 241 of 603, 40% vs. n = 19 of 483, 4·0%, P ≤ 0·001). Significantly more patients in these intervention stroke units received four-hourly temperature monitoring (n = 222 of 603, 37% vs. n = 90 of 483, 19%, P < 0·001) and six-hourly glucose monitoring (194 of 603, 32% vs. 46 of 483, 9·5%, P < 0·001) within 72 hours of admission to a stroke unit, and a swallowing screen (242 of 522, 46% vs. 24 of 350, 6·8%, P ≤ 0·0001) within the first 24 hours of admission to hospital. There was no difference between the groups in the treatment of patients with fever with paracetamol (22 of 105, 21% vs. 38 of 131, 29%, P = 0·78) or their hyperglycemia with insulin (40 of 100, 40% vs. 17 of 57, 30%, P = 0·49). Our intervention resulted in better protocol adherence in intervention stroke units

    We assessed patient outcomes 90 days after hospital admission for stroke following a multidisciplinary intervention targeting evidence-based management of fever, hyperglycaemia, and swallowing dysfunction in acute stroke units (ASUs). In the Quality in Acute Stroke Care (QASC) study, a single-blind cluster randomised controlled trial, we randomised ASUs (clusters) in New South Wales, Australia, with immediate access to CT and on-site high dependency units, to intervention or control group. Patients were eligible if they spoke English, were aged 18 years or older, had had an ischaemic stroke or intracerebral haemorrhage, and presented within 48 h of onset of symptoms. Intervention ASUs received treatment protocols to manage fever, hyperglycaemia, and swallowing dysfunction with multidisciplinary team building workshops to address implementation barriers. Control ASUs received only an abridged version of existing guidelines. We recruited pre-intervention and post-intervention patient cohorts to compare 90-day death or dependency (modified Rankin scale [mRS] ≥2), functional dependency (Barthel index), and SF-36 physical and mental component summary scores. Research assistants, the statistician, and patients were masked to trial groups. All analyses were done by intention to treat. This trial is registered at the Australia New Zealand Clinical Trial Registry (ANZCTR), number ACTRN12608000563369. 19 ASUs were randomly assigned to intervention (n=10) or control (n=9). Of 6564 assessed for eligibility, 1696 patients' data were obtained (687 pre-intervention; 1009 post-intervention). Results showed that, irrespective of stroke severity, intervention ASU patients were significantly less likely to be dead or dependent (mRS ≥2) at 90 days than control ASU patients (236 [42%] of 558 patients in the intervention group vs 259 [58%] of 449 in the control group, p=0·002; number needed to treat 6·4; adjusted absolute difference 15·7% [95% CI 5·8-25·4]).

    Background COPD is a common problem associated with morbidity and mortality. COPD may also affect the dynamics and coordination of functions such as swallowing. A misdirected swallow may, in turn, result in the bolus entering the airway. A growing body of evidence suggests that a subgroup of people with COPD is prone to oropharyngeal dysphagia. The aim of this study was to evaluate swallowing dysfunction in patients with stable COPD and to determine the relation between signs and symptoms of swallowing dysfunction and lung function (forced expiratory volume in 1 second percent predicted). Methods Fifty-one patients with COPD in a stable phase participated in a questionnaire survey, swallowing tests, and spirometry. A post-bronchodilator ratio of the forced expiratory volume in 1 second/best of forced vital capacity and vital capacity <0.7 was used to define COPD. Swallowing function was assessed by a questionnaire and two swallowing tests (water and cookie swallow tests). Results Sixty-five percent of the patients reported subjective signs and symptoms of swallowing dysfunction in the questionnaire and 49% showed measurable ones in the swallowing tests. For the combined subjective and objective findings, 78% had a coexisting swallowing dysfunction. No significant difference was found between male and female patients. Conclusion Swallowing function is affected in COPD patients with moderate to severe airflow limitation, and the signs and symptoms of this swallowing dysfunction were subjective, objective, or both.

    Although unilateral vocal fold palsy (UVFP) is a common problem, data relating to swallowing dysfunction are sparse. We reviewed the clinical findings (method of presentation, underlying diagnosis and position of the vocal folds) of 30 patients and conducted a follow-up telephone survey. Outcome measures used were direct visualization of fold function, position and compensation. In addition, standardized speech and language assessments for swallowing dysfunction and dysphonia were noted and compared to presentation. Our study indicates that 56 per cent of patients with UVFP have associated dysphagia. Outcome with speech therapy is significant, with 73 per cent showing improvement. These data indicate a significant link between UVFP and swallowing dysfunction. There is a marked therapeutic benefit from voice therapy. Further work is required to evaluate the long-term outcomes and establish the mechanism of swallowing dysfunction in these patients.

    The swallow function is one of the strong defense mechanism against aspiration. Aspiration and pneumonia are unavoidable in patients with defective mechanism of swallowing. The aim of this study was to evaluate patients with recurrent pneumonia in terms of videofluoroscopic examination results. The study comprised fifty pediatric cases (22 boys, 28 girls) with an average age of 2.9 years (2 months-7.5 years) who were referred to our clinic due to suffering from recurrent pneumonia. The videofluoroscopic swallow study (VFSS) was performed on all patients. The presence of a correlation with pneumonia was investigated. In 45 of the children, VFSS results were not normal. Of the children, 41 had mental-motor retardation. The results of the videofluoroscopic study show that silent aspiration was the most common pathology in participants with the percentage of 40 (27.5% mild, 17.5% severe). Patients in the study had pneumonia with an incidence of 2.6 illnesses per year. Having one than more results on VFSS was found to be associated with more number of annual pneumonia episodes. Children with neurological impairments are at risk of recurrent acute pneumonia due to aspiration. Disturbances of swallowing phases should be remembered as a cause of pneumonia in these patients.

    Introduction: Recently, we found that swallowing dysfunction after curative (chemo) radiation (CH) RT has a strong negative impact on health-related quality of life (HRQoL), even more than xerostomia. The purpose of this study was to design a predictive model for swallowing dysfunction after curative radiotherapy or chemoradiation. Materials and methods: A prospective study was performed including 529 patients with head and neck squamous cell carcinoma (HNSCC) treated with curative (CH) RT. In all patients, acute and late radiation-induced morbidity (RTOG Acute and Late Morbidity Scoring System) was scored prospectively. To design the model univariate and multivariate logistic regression analyses were carried out with grade 2 or higher RTOG swallowing dysfunction at 6 months as the primary (SWALL 6months ) endpoint. The model was validated by comparing the predicted and observed complication rates and by testing if the model also predicted acute dysphagia and late dysphagia at later time points (12, 18 and 24 months). Results: After univariate and multivariate logistic regression analyses, the following factors turned out to be independent prognostic factors for SWALL 6months : T3-T4, bilateral neck irradiation, weight loss prior to radiation, oropharyngeal and nasopharyngeal tumours, accelerated radiotherapy and concomitant chemoradiation. By summation of the regression coefficients derived from the multivariate model, the Total Dysphagia Risk Score (TDRS) could be calculated. In the logistic regression model, the TDRS was significantly associated with SWALL 6months ((p 6months was 5%, 24% and 46% in case of low-, intermediate- and high-risk patients, respectively. These observed percentages were within the 95% confidence intervals of the predicted values. The TDRS risk group classification was also significantly associated with acute dysphagia (P < 0.001 at all time points) and with late swallowing dysfunction at 12, 18 and 24 months (p < 0.001 at all time points

    Swallowing disorders and respiratory impairment are frequent in Parkinson's disease (PD) patients, and aspiration pneumonia remains the leading cause of death among these subjects. The objective of this study was to investigate whether there is an association between pulmonary impairment and swallowing dysfunction in PD patients. A cross-sectional study with a comparison group was conducted with PD patients. Subjects were submitted to demographic questionnaires and underwent spirometric and videofluorographic assessments. Significance level was considered at 95% (p<0.05). Among 35 PD patients, 40% presented with swallowing complaints. However, 22% of the clinically asymptomatic patients presented airway food penetration when submitted to videofluoroscopy. In 20% of PD patients material entered the airways and there was contact with the vocal folds in 7%. However, there was an efficient cleaning with residue deglutition in almost all patients. No penetration/aspiration was detected among the controls. Respiratory parameters were below the normal predicted values in PD patients when compared to the healthy controls. These data suggest an association between pulmonary dysfunction and swallowing impairment in PD patients; even in patients without swallowing complaints, impaired pulmonary function can be detected.

    Dysphagia is common among patients with Parkinson's disease. Swallowing and its coordination with respiration is extremely important to achieve safety swallowing. Different tools have been used to assess this coordination, however the results have been inconsistent. We aimed to investigate this coordination in patients with Parkinson's disease using a non-invasive method. Signals of submental muscle activity, thyroid cartilage excursion, and nasal airflow during swallowing were recorded simultaneously. Five different water boluses were swallowed three times, and the data were recorded and analyzed. Thirty-seven controls and 42 patients with early-stage Parkinson's disease were included. The rates of non-expiratory/expiratory pre- and post-swallowing respiratory phase patterns were higher in the patients than in the controls (P Parkinson's disease, and safety compensation mechanisms were used more than efficiency during swallowing. The results of this study may serve as a baseline for further research into new treatment regimens and to improve the management of swallowing in patients with Parkinson's disease.

    Swallowing dysfunction has been reported in Duchenne muscular dystrophy (DMD), but has not been studied in Becker muscular dystrophy (BMD). The aims of this study were to report the characteristics of swallowing dysfunction in BMD compared with DMD. The study participants were 18 patients with BMD and 18 patients with DMD. All the patients were examined using videofluorography during swallowing of 5 mL of fluid. The penetration-aspiration scale (P-A scale) and the videofluorographic dysphagia scale (VDS) were used to evaluate dysphagia. Swinyard functional ability stage was not significantly different between the BMD and DMD groups. Rate of aspiration, P-A scale score, and total VDS score did not differ across groups, but the VDS item score for laryngeal elevation was lower in the BMD group than in the DMD group (median scores 4.5 and 9, respectively; p Becker muscular dystrophy (BMD) was not well known. Eighteen patients with BMD and 18 patients with Duchenne muscular dystrophy were examined with videofluorography. Patients with BMD have swallowing problems similar to those observed in patients with DMD.

    The purpose of this large multicentre prospective cohort study was to identify which dose volume histogram parameters and pre-treatment factors are most important to predict physician-rated and patient-rated radiation-induced swallowing dysfunction (RISD) in order to develop predictive models for RISD after curative (chemo) radiotherapy ((CH) RT). The study population consisted of 354 consecutive head and neck cancer patients treated with (CH) RT. The primary endpoint was grade 2 or more swallowing dysfunction according to the RTOG/EORTC late radiation morbidity scoring criteria at 6 months after (CH) RT. The secondary endpoints were patient-rated swallowing complaints as assessed with the EORTC QLQ-H&N35 questionnaire. To select the most predictive variables a multivariate logistic regression analysis with bootstrapping was used. At 6 months after (CH) RT the bootstrapping procedure revealed that a model based on the mean dose to the superior pharyngeal constrictor muscle (PCM) and mean dose to the supraglottic larynx was most predictive. For the secondary endpoints different predictive models were found: for problems with swallowing liquids the most predictive factors were the mean dose to the supraglottic larynx and radiation technique (3D-CRT versus IMRT). For problems with swallowing soft food the mean dose to the middle PCM, age (18-65 versus >65 years), tumour site (naso/oropharynx versus other sites) and radiation technique (3D-CRT versus IMRT) were the most predictive factors. For problems with swallowing solid food the most predictive factors were the mean dose to the superior PCM, the mean dose to the supraglottic larynx and age (18-65 versus >65 years). And for choking when swallowing the V60 of the oesophageal inlet muscle and the mean dose to the supraglottic larynx were the most predictive factors. Physician-rated and patient-rated RISD in head and neck cancer patients treated with (CH) RT cannot be predicted with univariate relationships between the

    Full Text Available Ferulic acid (FA, a phenolic phytochemical, has been reported to exert antioxidative and neuroprotective effects. In this study, we investigated the protective effects of FA against the dysfunction of the swallowing reflex induced by ligation of bilateral common carotid arteries (2VO in rats. In 2VO rats, topical administration of water or citric acid to the pharyngolaryngeal region evoked a diminished number of swallowing events with prolonged latency compared to sham-operated control rats. 2VO rats had an increased level of superoxide anion radical, and decreased dopamine and tyrosine hydroxylase enzyme levels in the striatum, suggesting that 2VO augmented cerebral oxidative stress and impaired the striatal dopaminergic system. Furthermore, substance P (SP expression in the laryngopharyngeal mucosa, which is believed to be positively regulated by dopaminergic signaling in the basal ganglia, was decreased in 2VO rats. Oral treatment with FA (30 mg/kg for 3 weeks (from one week before 2VO to two weeks after improved the swallowing reflex and maintained levels of striatal dopamine and laryngopharyngeal SP expression in 2VO rats. These results suggest that FA maintains the swallowing reflex by protecting the dopamine-SP system against ischemia-induced oxidative damage in 2VO rats.

Few studies have examined potential ways of improving swallowing function in this fragile patient group. The aim of this study was to evaluate swallowing dysfunction and carbonated liquid using videofluoroscopy in DLB and PDD patients. Methods: A total of 48 patients with DLB and PDD were referred for a clinical examination with videofluoroscopy. Descriptive overall assessments were provided at the time of the examination regarding swallowing function and the effects of different modifications, including carbonated thin liquid (CTL. Additionally, a repeated measures quantitative retrospective analysis has been performed comparing 1 thin liquids; 2 thickened liquids and 3 CTLs, with regard to the quantitative variables 1 pharyngeal transit time (PTT; 2 pharyngeal retention and 3 tracheal penetration. Results: In all, 40/48 (83% of the patients had a swallowing dysfunction, which was confirmed on videofluoroscopy, with 34/40 (85% patients having a pharyngeal-type dysfunction. A total of 14/40 (35% patients with an objective swallowing impairment did not have any subjective swallowing symptoms. Out of the patients with swallowing dysfunction, 87% had an overall improved swallowing function with carbonated liquid.

    Purpose: To investigate long-term swallowing function in oropharyngeal cancer patients treated with intensity-modulated radiotherapy (IMRT), and to identify novel dose-limiting criteria predictive for dysphagia. Methods and Materials: Thirty-one patients with Stage IV oropharyngeal squamous carcinoma enrolled on a Phase II trial were prospectively evaluated by modified barium swallow studies at baseline, and 6, 12, and 24 months post-IMRT treatment. Candidate dysphagia-associated organs at risk were retrospectively contoured into original treatment plans. Twenty-one (68%) cases were base of tongue and 10 (32%) were tonsil. Stage distribution was T1 (12 patients), T2 (10), T3 (4), T4 (2), and TX (3), and N2 (24), N3 (5), and NX (2). Median age was 52.8 years (range, 42-78 years). Thirteen patients (42%) received concurrent chemotherapy during IMRT. Thirteen (42%) were former smokers. Mean dose to glottic larynx for the cohort was limited to 18 Gy (range, 6-39 Gy) by matching IMRT to conventional low-neck fields. Results: Dose-volume constraints (V30 < 65% and V35 < 35% for anterior oral cavity and V55 < 80% and V65 < 30% for high superior pharyngeal constrictors) predictive for objective swallowing dysfunction were identified by univariate and multivariate analyses. Aspiration and feeding tube dependence were observed in only 1 patient at 24 months. Conclusions: In the context of glottic laryngeal shielding, we describe candidate oral cavity and superior pharyngeal constrictor organs at risk and dose-volume constraints associated with preserved long-term swallowing function; these constraints are currently undergoing prospective validation. Strict protection of the glottic larynx via beam-split IMRT techniques promises to make chronic aspiration an uncommon outcome.

    Full Text Available Background: Swallowing changes are common in Parkinson′s disease (PD. Early identification is essential to avoid complications of aspiration. Objectives: To evaluate the swallowing ability of the PD patients and to correlate it with the indicators of disease progression. Materials and Methods: A total of 100 PD patients (70 males and 30 females aged between 50 years and 70 years with varying stage, duration, and severity were enrolled in a cross-sectional study carried out between January and May 2012. A simple bedside water swallowing test was performed using standard 150 ml of water. Swallowing process was assessed under three categories-swallowing speeds (ml/s, swallowing volume (ml/swallow and swallowing duration (s/swallow. Equal number of age and sex matched controls were also evaluated. Results: All of them completed the task of swallowing. A mean swallowing speed (27.48 ml/s, swallowing volume (28.5 ml/s, and swallowing duration (1.05 s/swallow was established by the control group. The PD patients showed decreased swallowing speed (7.15 ml/s in males and 6.61 ml/s in females, decreased swallowing volume (14.59 ml/swallow and 14 ml/swallow in females, and increased swallowing duration (2.37 s/swallow and 2.42 s/swallow which are statistically significant. There was a significant positive correlation between the severity, duration, and staging of the disease with the swallowing performance and a poor correlation between the subjective reports of dysphagia and the objective performance on water swallow test. Conclusion: The water swallowing test is a simple bedside test to identify the swallowing changes early in PD. It is recommended to do the test in all PD Patients to detect dysphagia early and to intervene appropriately.

    Dysphagia is relatively common in individuals with neurological disorders. To describe the swallowing management and investigate associated factors with swallowing in a case series of patients with Parkinson's disease. It is a long-term study with 24 patients. The patients were observed in a five-year period (2006-2011). They underwent Fiberoptic Endoscopic Evaluation of Swallowing, Functional Oral Intake Scale and therapeutic intervention every three months. In the therapeutic intervention they received orientation about exercises to improve swallowing. The Chi-square, Kruskal-Wallis and Fisher's tests were used. The period of time for improvement or worsening of swallowing was described by Kaplan-Meier analysis. During the follow-up, ten patients improved, five stayed the same and nine worsened their swallowing functionality. The median time for improvement was ten months. Prior to the worsening there was a median time of 33 months of follow-up. There was no associated factor with improvement or worsening of swallowing. The maneuvers frequently indicated in therapeutic intervention were: chin-tuck, bolus consistency, bolus effect, strengthening-tongue, multiple swallows and vocal exercises. The swallowing management was characterized by swallowing assessment every three months with indication of compensatory and rehabilitation maneuvers, aiming to maintain the oral feeding without risks. There was no associated factor with swallowing functionality in this case series. Copyright © 2014 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

    Purpose:To objectively assess swallowing function after an intensive chemoradiation regimen for locally advanced head-and-neck cancer and to assess the clinical implications of swallowing dysfunction. Patients and Methods:Twenty-nine patients with nonresectable Stage IV head-and-neck cancer participated in a Phase I study of radiation, 70 Gy/7 weeks, concurrent with weekly gemcitabine. Because of a high rate of mucosal toxicity, reduced drug doses were delivered to subsequent patient groups: 300, 150, 50, and 10 mg/m 2 /week. Twenty-six of these patients underwent prospective evaluation of swallowing function with videofluoroscopy and esophagogram. Studies were performed pretherapy, early post-therapy (1-3 months), and late post-therapy (6-12 months). Results:Complete tests were performed pretherapy in 22 patients, early post-therapy in 20, and late post-therapy in 13. Twenty-five patients had at least one post-therapy study. Post-therapy dysfunction was characterized by reduced inversion of the epiglottis, delayed swallow initiation and uncoordinated timing of the propulsion of the bolus, opening of the cricopharyngeal muscle, and closure of the larynx, all of which promoted aspiration during and after the swallow. In addition, reduced base-of-tongue retraction with reduced contact to the posterior pharyngeal wall and incomplete cricopharyngeal relaxation resulted in pooling in the pyriform sinuses and vallecula of residue, which was frequently aspirated after the swallow. Post-therapy aspirations were typically ''silent,'' eliciting no cough reflex, or the cough was delayed and noneffective in expelling the residue. Aspiration was observed in 3 patients (14%) in the pretherapy studies, in 13 (65%) in the early post-therapy studies, and in 8 (62%) in the late post-therapy studies (aspiration rates post-therapy vs. pretherapy: p=0.0002). Six patients had pneumonia requiring hospitalization 1-14 months after therapy (median: 2.5 months), being the likely cause of

    Patients with Parkinson's disease (PD) have progressive and pervasive disorders of airway protection. Recent work has highlighted the relationship between reflex and voluntary cough and swallowing safety. The goal of this study was to test the sensitivity and specificity of several airway protective and disease-specific factors for predicting swallowing safety outcomes in PD. Sixty-four participants (44 males) completed measures of voluntary and reflex cough, and swallowing safety. Clinical predictors included disease severity and duration, and cough airflow and sensitivity measures. ROC and Chi-square analyses identified predictors of swallowing safety (penetration-aspiration score) in PD. Disease duration significantly discriminated between patients with normal and abnormal swallowing safety (p = 0.027, sensitivity: 71 %, specificity: 55.4 %). Cough reflex sensitivity significantly discriminated between patients who penetrated above the level of the vocal folds and those with more severe penetration/aspiration (p = 0.021, sensitivity: 71.0 %, specificity 57.6 %). Urge-to-cough sensitivity (log-log linear slope) was the only variable which significantly discriminated between patients with penetration versus aspiration (p = 0.017, sensitivity: 85.7 %, specificity 73.2 %). It is important to identify the factors which influence airway protective outcomes in PD especially given that aspiration pneumonia is a leading cause of death. Results from this study highlight the ecological validity of reflex cough in the study of airway protection and this study further identifies important factors to consider in the screening of airway protective deficits in PD.

    Advanced lung cancer can cause changes to swallowing and communication function. Direct tumour invasion, dyspnoea and deconditioning can all impact on swallowing function and communication. Cancer treatment, if administered, may cause or compound symptoms. In this study, the nature of swallowing and communication difficulties in patients with advanced lung cancer will be discussed, and management options including medical management, speech and language therapy (SLT) intervention, and surgical interventions will be considered. Advanced lung cancer can result in voice and swallowing difficulties, which can increase symptom burden and significantly impact on quality of life (QOL). There is a growing evidence base to support the use of injection laryngoplasty under local anaesthetic to offer immediate improvement in voice, swallowing and overall QOL. There is limited literature on the nature and extent of voice and swallowing impairment in patients with lung cancer. Well designed studies with robust and sensitive multidimensional dysphagia and dysphonia assessments are required. Outcome studies examining interventions with clearly defined treatment goals are required. These studies should include both functional and patient-reported outcome measures to develop the evidence base and to ensure that interventions are both timely and appropriate.

    To describe the use of fiberoptic endoscopic evaluation of swallowing (FEES) as an adjunct in the management of children presenting with psychogenic dysphagia, defined as food avoidance and excessive fear of eating without identifiable anatomic or functional swallowing abnormalities. Case series of patients presenting to the otolaryngology clinic of a tertiary pediatric teaching hospital between 2007 and 2008 that were evaluated and managed with the utilization of FEES. The outcomes measured were age, gender, duration of symptoms, findings of FEES, additional work-up and resolution of symptoms at follow-up. Five patients (4 males, 1 female) with ages ranging from 5 to 13 years old (mean=8.6). The median duration of symptoms before presentation was 3 weeks. Four families described refusal of solids starting after choking episode and variable estimated weight loss (mean 2.8kg). One child presented with vague complaints of intermittent odynophagia and food refusal. Fiberoptic endoscopic evaluation of swallowing was performed on all patients. No abnormalities of the oropharyngeal swallow were appreciated. Additional management included different combinations of modified barium swallow study, esophagastroduodenoscopy (EGD), upper GI series, antibiotics, and psychotherapy. Mean follow-up with clinic visit was 4.2 months. Three of the five children reported complete resolution of symptoms after FEES at follow-up visit. Fiberoptic endoscopic evaluation of swallowing can be a useful management tool in children with psychogenic dysphagia as it provides direct visualization of the oropharyngeal swallowing mechanism. This can be used to provide visual reassure and biofeedback to patients and parents. Additional workup should be decided on an individual basis. Copyright © 2014 Elsevier Ireland Ltd.

    Dysphagia is one of the most important treatment-related side effects in head and neck cancer (HNC), as it can lead to severe life-threating complications such as aspiration pneumonia and malnutrition. Intensity-modulated radiotherapy (IMRT) could reduce swallowing dysfunction by producing a concave dose distribution and reducing doses to the swallowing-related organs at risk (SWOARs). The aim of this study was to review the current literature in order to compare swallowing outcomes between IMRT and three-dimensional conformal radiotherapy (3DCRT). A search was conducted in the PubMed and Embase databases to identify studies on swallowing outcomes, both clinically and/or instrumentally assessed, after 3DCRT and IMRT. Dysphagia-specific quality of life and objective instrumental data are summarized and discussed. A total of 262 papers were retrieved from the searched databases. An additional 23 papers were retrieved by hand-searching the reference lists. Ultimately, 22 papers were identified which discussed swallowing outcomes after 3DCRT and IMRT for HNC. No outcomes from randomized trials were identified. Despite several methodological limitations, reports from the current literature seem to suggest better swallowing outcomes with IMRT compared to 3DCRT. Further improvements are likely to result from the increased use of IMRT plans optimized for SWOAR sparing. (orig.) [de

    Cough is important for airway clearance, particularly if penetration/aspiration of foreign material occurs during swallow. Measures of voluntary cough production from ten male participants with stage II–III Parkinson’s disease (PD) who showed no videofluorographic evidence of penetration/aspiration (Group 1) were examined and compared with those of ten male participants with stage II–III PD who showed videofluorographic evidence of penetration/aspiration (Group 2). The degree of penetration/ aspiration was expertly judged from the videofluorographic examinations of the participants’ sequential swallow of a thin, 30-cc bolus. Measured cough parameters included inspiratory phase duration, inspiratory peak flow, compression phase duration, expiratory peak flow, expiratory rise time, and cough volume acceleration. Results indicated significant group differences for the majority of cough measures, except for inspiratory phase duration and inspiratory peak flow. A modest relationship existed between voluntary cough parameters and penetration/aspiration scores. Decreased ability to adequately clear material from the airway with voluntary cough may exacerbate symptoms resulting from penetration/aspiration, particularly for those with neurodegenerative disease. Measurement of voluntary cough may be useful for the evaluation of airway clearance ability. PMID:18483823

    The larynx is one of the most highly innervated organs in humans and serves a number of vitally important, complex, and highly evolved biological functions. On a day-to-day basis, the larynx functions autonomously, addressing several roles including airway protection, swallowing, and phonation. In some situations the larynx appears to adopt a functional state that could be considered maladaptive or "dysfunctional." This laryngeal dysfunction can underpin and account for a number of respiratory symptoms that otherwise appear incongruous with a clinical disease state and/or contribute to the development of symptoms that appear "refractory" to treatment. These include conditions associated with a heightened tendency for inappropriate laryngeal closure (e.g., inducible laryngeal obstruction), voice disturbance, and chronic cough. Recognition of laryngeal dysfunction is important to deliver targeted treatment and failure to recognize the condition can lead to repeated use of inappropriate treatment. Diagnosis is not straightforward, however, and many patients appear to present with symptoms attributable to laryngeal dysfunction, but in whom the diagnosis has been overlooked in clinical work-up for some time. This review provides an overview of the current state of knowledge in the field of laryngeal dysfunction, with a focus on pragmatic clinical assessment and management.

    Communication and swallowing disorders are highly prevalent in people with Parkinson's disease (PD). Maintenance of functional communication and swallowing over time is challenging for the person with PD and their families and may lead to social isolation and reduced quality of life if not addressed. Speech and language therapists (SLTs) face the conundrum of providing sustainable and flexible services to meet the changing needs of people with PD. Motor, cognitive and psychological issues associated with PD, medication regimens and dependency on others often impede attendance at a centre-based service. The access difficulties experienced by people with PD require a disruptive service approach to meet their needs. Technology-enabled management using information and telecommunications technologies to provide services at a distance has the potential to improve access, and enhance the quality of SLT services to people with PD. To report the status and scope of the evidence for the use of technology in the management of the communication and swallowing disorders associated with PD. Studies were retrieved from four major databases (PubMed, CINAHL, EMBASE and Medline via Web of Science). Data relating to the types of studies, level of evidence, context, nature of the management undertaken, participant perspectives and the types of technologies involved were extracted for the review. A total of 17 studies were included in the review, 15 of which related to the management of communication and swallowing disorders in PD with two studies devoted to participant perspectives. The majority of the studies reported on the treatment of the speech disorder in PD using Lee Silverman Voice Treatment (LSVT LOUD ® ). Synchronous and asynchronous technologies were used in the studies with a predominance of the former. There was a paucity of research in the management of cognitive-communication and swallowing disorders. Research evidence supporting technology-enabled management of the

    To clarify the role of external-beam radiotherapy in the local management of state IVB esophageal cancer. We reviewed records of 31 patients with histopathologically-proven squamous cell carcinoma who underwent radiotherapy for their primary lesion. The change in dysphagia score from before to after treatment was assessed. Nutritional support-free survival (NSFS) was also evaluated. The median overall survival was 6 months. The overall rate of improvement in dysphagia score was 73% (23/31). The median NSFS was 5 months. Age at presentation esophageal cancer is an effective treatment option for dysphagia. Factors highly associated with improvement of swallowing are age, tumor location, and tumor length. Response to radiotherapy is the most important factor in improving NSFS.

    Management of patients with dysphagia, regurgitation, and related symptoms after antireflux surgery is challenging. This prospective, case-control study tested the hypothesis that compared with standard high-resolution manometry (HRM) with single water swallows (SWS), adding multiple water swallows (MWS) and a solid test meal increases diagnostic yield and clinical impact of physiological investigations. Fifty-seven symptomatic and 12 asymptomatic patients underwent HRM with SWS, MWS, and a solid test meal. Dysphagia and reflux were assessed by validated questionnaires. Diagnostic yield of standard and full HRM studies with 24-hour pH-impedance monitoring was compared. Pneumatic dilatation was performed for outlet obstruction on HRM studies. Clinical outcome was assessed by questionnaires and an analogue scale with "satisfactory" defined as at least 40% symptom improvement requiring no further treatment. Postoperative esophagogastric junction pressure was similar in all groups. Abnormal esophagogastric junction morphology (double high pressure band) was more common in symptomatic than in control patients (13 of 57 vs 0 of 12, P = .004). Diagnostic yield of HRM was 11 (19%), 11 (19%), and 33 of 57 (58%), with SWS, MWS, and solids, respectively (P dysphagia (19 of 27, 70%). Outlet obstruction was present in 4 (7%), 11 (19%), and 15 of 57 patients (26%) with SWS, MWS, and solids, respectively (P < .009). No asymptomatic control had clinically relevant dysfunction on solid swallows. Dilatation was performed in 12 of 15 patients with outlet obstruction during the test meal. Symptom response was satisfactory, good, or excellent in 7 of 12 (58%) with no serious complications. The addition of MWS and a solid test meal increases the diagnostic yield of HRM studies in patients with symptoms after fundoplication and identifies additional patients with outlet obstruction who benefit from endoscopic dilatation.

    The Quality in Acute Stroke Care (QASC) trial evaluated systematic implementation of clinical treatment protocols to manage fever, sugar, and swallow (FeSS protocols) in acute stroke care. This cluster-randomised controlled trial was conducted in 19 stroke units in Australia. To describe perceived barriers and enablers preimplementation to the introduction of the FeSS protocols and, postimplementation, to determine which of these barriers eventuated as actual barriers. Preimplementation: Workshops were held at the intervention stroke units (n = 10). The first workshop involved senior clinicians who identified perceived barriers and enablers to implementation of the protocols, the second workshop involved bedside clinicians. Postimplementation, an online survey with stroke champions from intervention sites was conducted. A total of 111 clinicians attended the preimplementation workshops, identifying 22 barriers covering four main themes: (a) need for new policies, (b) limited workforce (capacity), (c) lack of equipment, and (d) education and logistics of training staff. Preimplementation enablers identified were: support by clinical champions, medical staff, nursing management and allied health staff; easy adaptation of current protocols, care-plans, and local policies; and presence of specialist stroke unit staff. Postimplementation, only five of the 22 barriers identified preimplementation were reported as actual barriers to adoption of the FeSS protocols, namely, no previous use of insulin infusions; hyperglycaemic protocols could not be commenced without written orders; medical staff reluctance to use the ASSIST swallowing screening tool; poor level of engagement of medical staff; and doctors' unawareness of the trial. The process of identifying barriers and enablers preimplementation allowed staff to take ownership and to address barriers and plan for change. As only five of the 22 barriers identified preimplementation were reported to be actual barriers at

    In Nigeria, the prevalence of erectile dysfunction (ED) among patients attending primary care clinics, age-standardized to the U.S. population in 2000 is 57.4%. This is considered high enough to warrant the attention of scientist for critical studies and analysis. The high ED prevalence is associated with etiologies such as psychosexual factors, chronic medical conditions, and some lifestyles. ED constitutes a major public health problem, influencing the patient's well-being and quality of life. It also leads to broken homes and marriages, psychological, social, and physical morbidity. To give an account of various ED management options in Nigeria. Review of peer-reviewed literature, questionnaire, and ethnobotanical survey to some indigenous herb sellers and herbalists. Cross cultural perspectives of ED management in Nigeria. The review suggests that traditional (phytotherapy, zootherapy, and occultism) and nontraditional, orthodox practice (drug therapy, psychological, and behavioral counseling) are applicable to ED management in Nigeria. This review should help in creating awareness into various options available for managing ED in the country, but does not recommend self medication of any form, be it the use of orthodox or herbal remedy.

    ventilation, and comorbities as stroke, correlate with this increased threat in intensive care unit (ICU patients. Recognition of deglutition dysfunction may identify patients at high risk of aspiration, and thereby help to avoid pulmonary complications such as recurrent pneumonia. The goal of our report is show a severe case of recurrent aspirative pneumonia after acute stroke and intubation, alerting to appropriate diagnosis and treatment of this condition. CASE REPORT: A male patient, 57 year old, was admitted to the hospital because of acute stroke. Ten days later, the patient began to have fever and severe shortness of breath. He was admitted to the ICU necessitating of intratracheal intubation. Four days after intubation he was extubated, however, he had a new aspirative pneumonia in ICU, newly treated. An evaluation of swallowing demonstrated a severe deglutition dysfunction with a high risk of aspiration. The patient was transferred, but aspirative pneumonia was diagnosed eight days after his ICU discharge and he was readmitted, stayed for a long time in ICU and presenting severe morbidity. CONCLUSIONS: ICU patients who are at risk for swallowing dysfunction and aspiration should be identified to prevent their associated morbidity and mortality.

    Disorders of swallowing are poorly characterized but quite common in schizophrenia. They are a source of considerable morbidity and mortality in this population, generally as a result of either acute asphyxia from airway obstruction or more insidious aspiration and pneumonia. The death rate from acute asphyxia may be as high as one hundred times that of the general population. Most swallowing disorders in schizophrenia seem to fall into one of two categories, changes in eating and swallowing due to the illness itself and changes related to psychotropic medications. Behavioral changes related to the illness are poorly understood and often involve eating too quickly or taking inappropriately large boluses of food. Iatrogenic problems are mostly related to drug-induced extrapyramidal side effects, including drug-induced parkinsonism, dystonia, and tardive dyskinesia, but may also include xerostomia, sialorrhea, and changes related to sedation. This paper will provide an overview of common swallowing problems encountered in patients with schizophrenia, their pathophysiology, and management. While there is a scarcity of quality evidence in the literature, a thorough history and examination will generally elucidate the predominant problem or problems, often leading to effective management strategies.

    Lower urinary tract dysfunction is an umbrella diagnosis that covers difficulty evacuating urine from the bladder. In its most simple form, it is either an inability to store urine or an inability to empty the bladder of urine appropriately. The normal and the abnormal bladder, the role of urodynamics in evaluation of lower urinary tract dysfunction, and the medical and behavioral management of some of these disorders are reviewed.

    In critically ill patients, the right ventricle is susceptible to dysfunction due to increased afterload, decreased contractility, or alterations in preload. With the increased use of point-of-care ultrasonography and a decline in the use of pulmonary artery catheters, echocardiography can be the ideal tool for evaluation and to guide hemodynamic and respiratory therapy. We review the epidemiology of right ventricular failure in critically ill patients; echocardiographic parameters for evaluating the right ventricle; and the impact of mechanical ventilation, fluid therapy, and vasoactive infusions on the right ventricle. Finally, we summarize the principles of management in the context of right ventricular dysfunction and provide recommendations for echocardiography-guided management.

    Phosphodiesterase 5 (PDE5) inhibitors are recommended as first line therapy for the treatment of erectile dysfunction (ED). To date, three PDE5 inhibitors are on the market: sildenafil, vardenafil and tadalafil. These compounds are available as oral tablets; they are rapidly absorbed in the gastrointestinal tract and are excreted mainly in the fces and to a lexer extent in the urine. Recently, an orodisnersible formulation of feces and, to a lesser extent, in the urine. Recently, an orodispersible formulation of vardenafil (vardenafil ODT) has been developed, which is able to dissolve in the mouth within seconds, releasing a minty flavor, without the need of being swallowed with water. The clinical studies so far performed showed that vardenafil ODT has a bioavailability superior to the traditional film-coated tablet. Among the other PDE5 inhibitors under development we report mirodenafil, lodenafil carbonate, avalafil and SLx-2101 It is likely that in the future molecules that act on pathways other than the one of NO/cGMP will be available. Such as Rho-kinase inhibitors, which inhibit the mechanism that leads to smooth muscle contraction thus allowing erection and hydrogen sulphide (H2S), an endogenous molecule synthesized from cysteine that can be both a vasodilator and a vasoconstrictor according to its concentration.

    Temporomandibular disorders (TMD) are a subgroup of craniofacial pain problems involving the temporomandibular joint (TMJ), masticatory muscles, and associated head and neck musculoskeletal structures. These disorders are subclassified into TMJ articular disorders and masticatory muscle disorders. Patients with TMD most commonly present with pain, restricted or asymmetric mandibular motion, and TMJ sounds during mandibular movements. The prevalence tends to increase with age. Management of TMJ articular disorders consists of a combination of patient education, home-care plan, biobehavioral therapy, physical therapy, orthotic jaw appliance therapy, pharmacotherapy, and/or surgery. The goal is to increase function, reduce pain, and improve quality of life. Copyright © 2017 Elsevier Inc. All rights reserved.

  12. Sacroiliac Joint Dysfunction in the Athlete: Diagnosis and Management.

    Science.gov (United States)

    Peebles, Rebecca; Jonas, Christopher E

    Sacroiliac joint (SIJ) dysfunction is a common cause of low back pain in the athlete, especially in sports with repetitive, asymmetric loading. Complex anatomy and broad pain referral pattern make diagnosis difficult. Identifying three or more positive physical examination maneuvers for the SIJ improves examination sensitivity and specificity. Imaging is rarely helpful in establishing the diagnosis but is often used to rule out other pathology. Conservative management with activity modification, medication, physical therapy, manipulation and bracing is first line treatment. After at least 6 weeks of conservative efforts or if pain limits the athlete's tolerance of these measures, diagnostic and therapeutic intra-articular or periarticular injections or nerve blocks can be used. Radiofrequency ablation is recommended as the next approach for treatment. When all other options have been exhausted, surgical management can be considered. For athletes, once the underlying dysfunction is adequately addressed, gradual progression to full participation is encouraged.

    he occurrence of esophageal and gastric motor dysfunctions happens, when the software of the esophagus and the stomach is injured. This is really a program previously established in the enteric nervous system as a constituent of the newly called neurogastroenterology. The enteric nervous system is composed of small aggregations of nerve cells, enteric ganglia, the neural connections between these ganglia, and nerve fibers that supply effectors tissues, including the muscle of the gut wall. The wide range of enteric neuropathies that includes esophageal achalasia and gastroparesis highlights the importance of the enteric nervous system. A classification of functional gastrointestinal disorders based on symptoms has received attention. However, a classification based solely in symptoms and consensus may lack an integral approach of disease. As an alternative to the Rome classification, an international working team in Bangkok presented a classification of motility disorders as a physiology-based diagnosis. Besides, the Chicago Classification of esophageal motility was developed to facilitate the interpretation of clinical high-resolution esophageal pressure topography studies. This review covers exclusively the medical and surgical management of the esophageal and gastric motor dysfunction using evidence from well-designed studies. Motor control of the esophagus and the stomach, motor esophageal and gastric alterations, treatment failure, side effects of PPIs, overlap of gastrointestinal symptoms, predictors of treatment, burden of GERD medical management, data related to conservative treatment vs. antireflux surgery, and postsurgical esophagus and gastric motor dysfunction are also taken into account.

    Full Text Available Alan Saleh, Hamid Abboudi, MB Ghazal-Aswad, Erik K Mayer, Justin A Vale Division of Surgery and Cancer, Imperial College Healthcare NHS Trust, St Mary's Hospital, London, UK Abstract: Radical prostatectomy is a commonly performed procedure for the treatment of localized prostate cancer. One of the long-term complications is erectile dysfunction. There is little consensus on the optimal management; however, it is agreed that treatment must be prompt to prevent fibrosis and increase oxygenation of penile tissue. It is vital that patient expectations are discussed, a realistic time frame of treatment provided, and treatment started as close to the prostatectomy as possible. Current treatment regimens rely on phosphodiesterase 5 inhibitors as a first-line therapy, with vacuum erection devices and intraurethral suppositories of alprostadil as possible treatment combination options. With nonresponders to these therapies, intracavernosal injections are resorted to. As a final measure, patients undergo the highly invasive penile prosthesis implantation. There is no uniform, objective treatment program for erectile dysfunction post-radical prostatectomy. Management plans are based on poorly conducted and often underpowered studies in combination with physician and patient preferences. They involve the aforementioned drugs and treatment methods in different sequences and doses. Prospective treatments include dietary supplements and gene therapy, which have shown promise with there proposed mechanisms of improving erectile function but are yet to be applied successfully in human patients.

    2017-03-01

    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.

    Full Text Available Dominick L Opitz,1 Jennifer S Harthan,1 Stephanie R Fromstein,1 Scott G Hauswirth2 1Department of Clinical Education, Illinois College of Optometry, Chicago, IL, 2Minnesota Eye Consultants, Minneapolis, MN, USA Abstract: Meibomian gland dysfunction (MGD is commonly encountered among eye care professionals. Our understanding of the pathophysiology for the development of MGD has greatly expanded in recent years, which helped increase awareness of the disease. Despite increased awareness, it is essential for eye care professionals to make a conscious effort to properly examine the meibomian glands through gland expression even for asymptomatic patients. At minimum, early management should include patient education and supportive therapy such as warm compresses, lid hygiene, and gland expression. As patients become more symptomatic and as the ocular surface becomes more affected, employing additional therapeutic management is recommended and may include oral omega-3 essential fatty acids, topical azithromycin, oral tetracycline, and topical anti-inflammatories to improve clinical signs and patient comfort. In addition to treatment of MGD, clinicians should be mindful of the comorbid conditions of MGD and simultaneously manage them in conjunction of MGD treatment.

    The aim of this study was to evaluate late disturbance of food ingestion and swallowing in patients with advanced head and neck carcinoma after concurrent chemoradiotherapy (CCRT). Patients answered a questionnaire, the Quality of Life Radiation Therapy Instrument (QOL-RTI) for Japanese, and swallowing function was investigated by videoendoscopy (VE) more than 1 year after treatment. The results of patients after CCRT were compared with normal elderly serving as the control group. The total QOL score of the patient group was significantly lower than that of the control group. In terms of the results of the QOL questionnaires, the QOL scores for quantity of saliva, quality of saliva, taste and food swallowing were significantly lower in the patient group. Regarding the VE findings, the control group exhibited almost normal swallowing function, but pooling in the vallecura, laryngeal palsy and pooling in the hypopharynx were observed in the phase of not swallowing. Furthermore, dysfunction of swallowing using the colored water swallowing test was observed in about 40% of the patients. In addition, the factors associated with disturbance of QOL score and swallowing function were analyzed. All factors, id est (i.e.), age, T and N classification, stage, duration after treatment, acute toxicity of chemoradiotherapy and order of chemotherapy, had not influence on food ingestion or swallowing. Patients after CCRT might have potential dysfunction of swallowing. The colored water swallowing test is useful for diagnosis of swallowing dysfunction in head and neck cancer patients after CCRT.

    Surgery for patients with neurogenic urinary tract dysfunction (nLUTD) is indicated when medical therapy fails, to correct conditions affecting patient safety, or when surgery can enhance the quality of life better than nonoperative management. Examples include failure of maximal medical therapy, inability to perform or aversion to clean intermittent catheterization, refractory incontinence, and complications from chronic, indwelling catheters. Adults with nLUTD have competing risk factors, including previous operations, obesity, poor nutritional status, complex living arrangements, impaired dexterity/paralysis, and impaired executive and cognitive function. Complications are common in this subgroup of patients requiring enduring commitments from surgeons, patients, and their caretakers. Copyright © 2017 Elsevier Inc. All rights reserved.

    Closure of the laryngeal vestibule during swallowing is important for protection of the airways. The present investigation included 53 patients with dysphagia examined cineradiographically with the head held in resting posture, flexion and extension. The ability to protect the airways by the downward movement of the epiglottis and by obliteration of the laryngeal vestibule was studied in different postures of the head. Of 35 patients with normal laryngeal obliteration with the head in resting position 10 showed a defective closure at swallowing in extension. In 18 patients with defective closure of the laryngeal vestibule in resting position 9 were improved on flexion and two on extension of the head. In one patient with defectie closure of the laryngeal vestibule in resting position swallowing in flexion showed an aggravated dysfunction. In our other patients the defective closure became more marked on extension. Four patients had less effective downward movement of the epiglottis with the head in extension. Of 10 patients with defective epiglottic movement with the head in resting position two were improved on tilting the head forwards. The results show that the position of the head influences the closure of the airways during swallowing. Patients with defective protection of the laryngeal vestibule should be instructed to swallow with the head tilted forwards. (orig.)

    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. Here we present an overview of dysphagia and swallowing rehabilitation.

    2010-01-01

    Swallowing dysfunction, or dysphagia, is a serious condition that can result from any structural or neurological impairment (such as stroke, neurodegenerative disease or brain injury) that affects the swallowing mechanism. The gold-standard method of instrumental swallowing assessment is an x-ray examination known as the videofluoroscopic swallowing study, which involves radiation exposure. Consequently, there is interest in exploring the potential of less invasive methods, with lesser risks of biohazard, to accurately detect swallowing abnormalities. Accelerometry is one such technique, which measures the epidermal vibration signals on a patient's neck during swallowing. Determining the utility of accelerometry signals for detecting dysphagia requires an understanding of the physiological source of the vibrations that are measured on the neck during swallowing. The purpose of the current study was to determine the extent to which movement of the hyoid bone and larynx contributes to the vibration signal that is registered during swallowing accelerometry. This question was explored by mapping the movement trajectories of the hyoid bone and the arytenoid cartilages from lateral videofluoroscopy recordings collected during thin liquid swallowing, and comparing these trajectories to time-linked signals obtained from a dual-axis accelerometer placed on the neck, just anterior to the cricoid cartilage. Participants for this study included 43 adult patients referred for videofluoroscopic swallowing studies to characterize the nature and severity of suspected neurogenic dysphagia. A software program was created to allow frame-by-frame tracking of structural movement on the videofluoroscopy recordings. These movement data were then compared to the integrated acceleration data using multiple linear regressions. The results concur with previous studies, implicating hyolaryngeal excursion as the primary physiological source of swallowing accelerometry signals, with both

    Full Text Available Robot-assisted laparoscopic prostatectomy (RALP has emerged as the most common treatment for localized prostate cancer. With improved surgical precision, RALP has produced hope of improved potency rates, especially with the advent of nerve-sparing and other modified techniques. However, erectile dysfunction (ED remains a significant problem for many men regardless of surgical technique. To identify the functional outcomes of robotic versus open and laparoscopic techniques, new robotic surgical techniques and current treatment options of ED following RALP. A Medline search was performed in March 2014 to identify studies comparing RALP with open retropubic radical prostatectomy (RRP and laparoscopic radical prostatectomy, modified RALP techniques and treatment options and management for ED following radical prostatectomy. RALP demonstrates adequate potency rates without compromising oncologic benefit, with observed benefit for potency rates compared with RRP. Additionally, specific surgical technical modifications appear to provide benefit over traditional RALP. Phosphodiesterase-5 inhibitors (PDE5I demonstrate benefit for ED treatment compared with placebo. However, long-term benefit is often lost after use. Other therapies have been less extensively studied. Additionally, correct patient identification is important for greatest clinical benefit. RALP appears to provide beneficial potency rates compared with RRP; however, these effects are most pronounced at high-volume centers with experienced surgeons. No optimal rehabilitation program with PDE5Is has been identified based on current data. Additionally, vacuum erection devices, intracavernosal injections and other techniques have not been well validated for post RALP ED treatment.

    2013-01-01

    We tested two hypotheses relating to the sensory deficit that follows a unilateral superior laryngeal nerve (SLN) lesion in an infant animal model. We hypothesized that it would result in (1) a higher incidence of aspiration and (2) temporal changes in sucking and swallowing. We ligated the right-side SLN in six 2–3-week-old female pigs. Using videofluoroscopy, we recorded swallows in the same pre- and post-lesion infant pigs. We analyzed the incidence of aspiration and the duration and latency of suck and swallow cycles. After unilateral SLN lesioning, the incidence of silent aspiration during swallowing increased from 0.7 to 41.5 %. The durations of the suck containing the swallow, the suck immediately following the swallow, and the swallow itself were significantly longer in the post-lesion swallows, although the suck prior to the swallow was not different. The interval between the start of the suck containing a swallow and the subsequent epiglottal movement was longer in the post-lesion swallows. The number of sucks between swallows was significantly greater in post-lesion swallows compared to pre-lesion swallows. Unilateral SLN lesion increased the incidence of aspiration and changed the temporal relationships between sucking and swallowing. The longer transit time and the temporal coordinative dysfunction between suck and swallow cycles may contribute to aspiration. These results suggest that swallow dysfunction and silent aspiration are common and potentially overlooked sequelae of unilateral SLN injury. This validated animal model of aspiration has the potential for further dysphagia studies. PMID:23417250

The following studies were conducted in plant Pests & Diseases Research Institute during the years 2003-4: 1- Effect of constant temperature on germination that including 10, 15, 18, 20, 25, 30, 35 and 40˚C; 2- Effect of light on constant germination; 3- Effect of temperature fluctuations on seed germination: 15/7, 20/12, 25/17 and 30/22˚C. All experiments were conducted with 8 replications. Swallow wort seeds showed no dormancy when detachment from mother plant. Seed germination was strongly influenced by temperature. Light did not play a crucial role on seed germination of this weed. Therefore Swallow wort seeds were not photoblastic and temperature fluctuations did not increase seed germination of Swallow wort. The above characteristics are very important in making swallowwort an invasive weed. Having precise information of these traits enables us to a better management and control of this troublesome weed.

  9. Recognition and Management of Nonrelaxing Pelvic Floor Dysfunction

    Nonrelaxing pelvic floor dysfunction is not widely recognized. Unlike in pelvic floor disorders caused by relaxed muscles (eg, pelvic organ prolapse or urinary incontinence, both of which often are identified readily), women affected by nonrelaxing pelvic floor dysfunction may present with a broad range of nonspecific symptoms. These may include pain and problems with defecation, urination, and sexual function, which require relaxation and coordination of pelvic floor muscles and urinary and anal sphincters. These symptoms may adversely affect quality of life. Focus on the global symptom complex, rather than the individual symptoms, may help the clinician identify the condition. The primary care provider is in a position to intervene early, efficiently, and effectively by (1) recognizing the range of symptoms that might suggest nonrelaxing pelvic floor dysfunction, (2) educating patients, (3) performing selective tests when needed to confirm the diagnosis, and (4) providing early referral for physical therapy.

    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.

    Impaired swallowing is common in elderly patients as well as those with neurological disorders and degenerative diseases. Convenient and accurate assessments should be available to community-dwelling older adults to diagnose and provide early management and care of swallowing difficulties, an important factor of influence on elderly life quality. This study used convenient nonimaging methods to assess swallowing functions in community-dwelling older adults and estimated the prevalence of swallowing difficulties. The study adopted a survey method and recruited 216 community-dwelling older adults over 65 years old in northern Taiwan. Researchers used tools including a swallowing test, questionnaire, water test, peripheral arterial pulse oximeter, and laryngeal S-EMG to assess participant swallowing functions and the prevalence of impaired swallowing. We found a 9.5% prevalence of impaired swallowing based on swallow questionnaire and water test results. Age correlated negatively with swallowing speed. A one-way ANOVA showed a significant difference in swallowing speed among the four age groups (F = 6.478, p < .00). A post hoc Scheffe comparison showed significant differences in swallowing time between the 60- to 69- and 70- to 79-year-old groups and 60- to 69- and 80- to 89-year-old groups. Multiple regression of impaired swallowing on various independent variables showed a significant standardized coefficient of 0.163 for age (t = 2.328, p = .021). Logistic regression showed a significant Wals test value for age (p = .007). The Kappa value was 0.307 for agreement analysis between impaired swallowing and SaO(2) value reduction of more than 2%. Swallowing function deteriorates with age. Results of this study provide an assessment of the prevalence of impaired swallowing in community-dwelling older adults in Taiwan. Results can help guide clinical nurses to enhance their objective assessment of impaired swallowing to improve patient quality of life.

    Oropharyngeal swallowing is too fast and complex a motion for the human eye to seize its various phases and subsequently evaluate morphology and function of the anatomical structures involved. A chronological subdivision of the swallowing act is needed for e step-by-step analysis. Dinamic evaluation of oropharyngeal swallowing by means of fluoroscopic and US videorecording proved to be a reliable method. Echovideorecording allowed tongue movements to be depicted, together with bolus formation and propulsion. Fluorovideorecording (U-Matic Sony unit, 25-30 images/sec) demonstrated pharyngeal and esophageal phases. A series of chronological and morphological reference points, which characterize oropharyngeal swallowing, were employed to analyze videorecorded images. Slowmotion mode, 'freezed' images, and rewinding allowed an easy and accurate evaluation of swallowing details. Combined chronological and morphological pieces of information allow a comprehensive evaluation of the swallowing act

    To find out the proportion of dysfunctional uterine bleeding (DUB) and the response of patients of DUB to medical treatment at Abbasi Shaheed Hospital. Results: Two hundred and ten out of 1300 patients were diagnosed as having DUB with the proportion of 16.1%. Response rate was 20 - 30 % with oral mafenamic acid, 50% with capsule tranexamic acid, 60% and 50% respectively with oral contraceptive pills containing ethinylestradiol and norethisterone, and norethisterone alone. The response rate with capsulated micronised flavonoid and derivative of ethinyltestosterone was 90% and 75% respectively. Conclusion: The patients in adolescent age group are good responders to conservative treatment. Most of the patients preferred micronised flavonoid over derivative of ethinyltestosterone for some misconceptions regarding this medicine. The former was better tolerated with less side effects.

    Acute kidney injury frequently develops following the term perinatal hypoxia-ischaemia. Quantifying the degree of acute kidney injury is difficult, however, as the methods currently in use are suboptimal. Acute kidney injury management is largely supportive with little evidence basis for many interventions. This review discusses management strategies and novel biomarkers that may improve diagnosis and management of renal injury following perinatal hypoxia-ischaemia.

    Recently, oropharyngeal cancer is more frequently being managed with concurrent chemoradiotherapy (CCRT). As more patients receive CCRT, there is increasing attention on dysphagia. Since 2009, speech therapists in our hospital have performed swallowing rehabilitation for dysphagia associated with CCRT. We evaluated dysphagia after CCRT and examined the relationship between swallowing rehabilitation and swallowing disability. A total of 26 patients (22 males and 4 females) with a mean age of 63 years (range, 41 to 79), underwent CCRT between March 2008 and March 2010. Dysphagia after treatment was graded at the end of CCRT and discharge according to Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 and Fujishima dysphagia grade. Ten of the 26 patients underwent swallowing rehabilitation, exercise and education on muscle strengthening programs before and during CCRT. They tended not to have severe dysphagia, but there were no significant differences. (author)

  2. Phytochemicals and the breakthrough of traditional herbs in the management of sexual dysfunctions.

    Adimoelja, A

    2000-01-01

    Traditional herbs have been a revolutionary breakthrough in the management of erectile dysfunction and have become known world-wide as an 'instant' treatment. The modern view of the management of erectile dysfunction subscribes to a single etiology, i.e. the mechanism of erection. A large number of pharmacological agents are orally consumed and vasoactive agents inserted intraurethrally or injected intrapenially to regain good erection. Modern phytochemicals have developed from traditional herbs. Phytochemicals focus their mechanism of healing action to the root cause, i.e. the inability to control the proper function of the whole body system. Hence phytochemicals manage erectile dysfunction in the frame of sexual dysfunction as a whole entity. Protodioscin is a phytochemical agent derived from Tribulus terrestris L plant, which has been clinically proven to improve sexual desire and enhance erection via the conversion of protodioscine to DHEA (De-Hydro-Epi-Androsterone). Preliminary observations suggest that Tribulus terrestris L grown on different soils does not consistently produce the active component Protodioscin. Further photochemical studies of many other herbal plants are needed to explain the inconsistent results found with other herbal plants, such as in diversities of Ginseng, Eurycoma longifolia, Pimpinella pruacen, Muara puama, Ginkgo biloba, Yohimbe etc.

    The management of Parkinson's disease (PD) has been improved, but management of signs like swallowing problems is still challenging. Deep brain stimulation (DBS) alleviates the cardinal motor symptoms and improves quality of life, but its effect on swallowing is not fully explored. The purpose of this study was to examine self-reported swallowing-specific quality of life before and after caudal zona incerta DBS (cZI DBS) in comparison with a control group. Nine PD patients (2 women and 7 men) completed the self-report Swallowing Quality of Life questionnaire (SWAL-QOL) before and 12 months after cZI DBS surgery. The postoperative data were compared to 9 controls. Median ages were 53 years (range, 40-70 years) for patients and 54 years (range, 42-72 years) for controls. No significant differences were found between the pre- or postoperative scores. The SWAL-QOL total scores did not differ significantly between PD patients and controls. The PD patients reported significantly lower scores in the burden subscale and the symptom scale. Patients with PD selected for cZI DBS showed good self-reported swallowing-specific quality of life, in many aspects equal to controls. The cZI DBS did not negatively affect swallowing-specific quality of life in this study.

    van Vliet, Paulette M; Heneghan, Nicola R

    2006-08-01

    This paper aims to develop understanding of three important motor control issues--feedforward mechanisms, cortical plasticity and task-specificity and assess the implications for musculoskeletal practice. A model of control for the reach-to-grasp movement illustrates how the central nervous system integrates sensorimotor processes to control complex movements. Feedforward mechanisms, an essential element of motor control, are altered in neurologically intact patients with chronic neck pain and low back pain. In healthy subjects, cortical mapping studies using transcranial magnetic stimulation have demonstrated that neural pathways adapt according to what and how much is practised. Neuroplasticity has also been demonstrated in a number of musculoskeletal conditions, where cortical maps are altered compared to normal. Behavioural and neurophysiological studies indicate that environmental and task constraints such as the goal of the task and an object's shape and size, are determinants of the motor schema for reaching and other movements. Consideration of motor control issues as well as signs and symptoms, may facilitate management of musculoskeletal conditions and improve outcome. Practice of entire everyday tasks at an early stage and systematic variation of the task is recommended. Training should be directed with the aim of re-educating feedforward mechanisms where necessary and the amount of practice should be sufficient to cause changes in cortical activity.

    2010-09-01

    Full Text Available Observation of the swallowing dynamics is an issue that demands close attention by the health professionals involved in the diagnosis and management of patients with dysphagia. This article is a review of the literature aimed to enhance the knowledge regarding the speech therapy assessment of pharyngeal dysphagia in elder adults. The disorder of the swallowing is called dysphagia and it is defined as difficulty swallowing. The dysphagia is often caused by affectation of mechanical or neuromuscular components of the swallowing mechanism. This type of disorder is likely to impact the the oral, pharyngeal and esophageal phases of the swallowing. The speech therapist should take into account assessing aspects such as level of consciousness, vital signs, whether or not the patient is ventilator dependent, means of feeding, if intubated what type of cannula, whether or not the patient uses a speaking valve (if a trach tube is present, nutritional status, the patient’s expressive and receptive language, the anatomical and physiological state of the oral motor structures. When assessing swallowing clinicians should also make sure to develop an adequate beside clinical, voice assessment and videofluoroscopy.

    Swallows of the north temperate zone display a wide variety of territorial behaviour during the breeding season, but as soon as breeding is over, they all appear to adopt a pattern of independent diurnal foraging interleaved with aggregation every night in dense roosts. Swallows generally migrate during the day, feeding on the wing. On many stretches of their annual journeys, their migrations can thus be seen as the simple spatial translation of nocturnal roost sites with foraging routes stra...

    Maxillectomy for oral tumours often results in debilitating oral hypofunction, which markedly decreases quality of life. Dysphagia, in particular, is one of the most serious problems following maxillectomy. This study used swallowing sounds as a simple evaluation method to evaluate swallowing ability in maxillectomy patients with and without their obturator prosthesis placed. Twenty-seven maxillectomy patients (15 men, 12 women; mean age 66.0 ± 12.1 years) and 30 healthy controls (14 men, 16 women; mean age 44.9 ± 21.3 years) were recruited for this study. Participants were asked to swallow 4 mL of water, and swallowing sounds were recorded using a throat microphone. Duration of the acoustic signal and duration of peak intensity (DPI) were measured. Duration of peak intensity was significantly longer in maxillectomy patients without their obturator than with it (P maxillectomy patients without their obturator than in healthy controls (P maxillectomy patients who had undergone soft palate resection than in those who had not (P maxillectomy patients could be improved by wearing an obturator prosthesis, particularly during the oral stage.

    To evaluate and describe the swallowing function in children after laryngeal cleft repair. Ten-year (2002-2012) retrospective chart review. Academic tertiary care pediatric otolaryngology practice. Records of 60 children who had surgical repair of laryngeal cleft (ages 2 weeks-14 years) and postoperative functional endoscopic evaluation of swallowing or videofluoroscopic swallow studies were examined retrospectively. Twenty-nine children had one postoperative swallow evaluation, 19 children had two, 4 children had three, 5 children had four, and 3 children had five. Median time to the first evaluation was 10.8 weeks (interquartile range [IQR]: 36.5, 231). On the final swallow evaluation, 34 (57%) children demonstrated normal swallowing parameters, 12 (20%) children showed penetration, and 14 (23%) children showed aspiration. Forty-three (72%) children were able to take everything by mouth normally or with minor behavioral modifications, 11 (18%) children required thickened fluids, and six (10%) children were kept nil per os (NPO). Mean improvement on the penetration-aspiration (pen-asp) scale was 2.13. On multivariable analysis, neurodevelopmental issues and gastronomy tube use were associated with the need for NPO status. Despite a high rate of surgical success, a substantial minority of children have persistent swallowing dysfunction after laryngeal cleft repair. Swallowing dysfunction after repair is multifactorial and arises from concomitant neurologic, anatomic, or other comorbidities that contribute to oropharyngeal and pharyngeal dysphagia. Based on our results, we recommend a testing schedule for postoperative swallowing evaluations after cleft repair. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    Background Dysfunction of mechanical heart valve prostheses is an unusual but potentially lethal complication after mechanical prosthetic valve replacement. We seek to report our experience with mechanical valve dysfunction regarding etiology, surgical techniques and early outcomes. Methods Clinical data of 48 patients with mechanical valve dysfunction surgically treated between October 1996 and June 2011 were analyzed. Results Mean age was 43.7±10.9 years and 34 were female (70.8%). The median interval from primary valve implantation to dysfunction was 44.5 months (range, 1 hour to 20 years). There were 21 emergent and 27 elective reoperations. The etiology was thrombosis in 19 cases (39.6%), pannus in 12 (25%), thrombosis and pannus in 11 (22.9%), improper disc orientation in 2 (4.1%), missing leaflet in 1 (2.1%), excessively long knot end in 1 (2.1%), endogenous factor in 1 (2.1%) and unidentified in 1 (2.1%). Surgical procedure was mechanical valve replacement in 37 cases (77.1%), bioprosthetic valve replacement in 7 (14.9%), disc rotation in 2 (4.2%) and excision of excessive knot end in 1 (2.1%). Early deaths occurred in 7 patients (14.6%), due to low cardiac output in 3 (6.3%), multi-organ failure in 2 (4.2%) and refractory ventricular fibrillation in 2 (4.2%). Complications occurred in 10 patients (20.8%). Conclusions Surgical management of mechanical valve dysfunction is associated with significant mortality and morbidity. Earlier identification and prompt reoperation are vital to achieving better clinical outcomes. The high incidence of thrombosis in this series highlights the need for adequate anticoagulation and regular follow-up after mechanical valve replacement. PMID:26793354

    To present the long-term outcomes of appendicovesicostomy using the Mitrofanoff principle for end-stage Wolfram bladder dysfunction as an alternative to clean intermittent self-catheterization (CIC) per urethra mainly following blindness. Twelve Wolfram patients presenting with bilateral hydroureteronephrosis and advanced bladder dysfunction were included in this study. All patients were managed initially by CIC per urethra. All of these patients became blind during follow-up and were unable to perform urethral CIC independently. Out of these patients, six patients agreed to proceed to appendicovesicostomy. Appendicovesicostomy urinary diversion using the Mitrofanoff principle was performed in these six blind patients. The rest of the patients stopped CIC or performed CIC irregularly. Severe hydroureteronephrosis and large bladders were found in all patients prior to intervention. All patients were able to conduct CIC independently through the stoma and maintained overnight bladder free drainage. In all patients with urinary diversion and CIC, the hydroureteronephrosis was reduced and renal function returned to normal. However, the non-intervention group ended with different degrees of progressive renal failure with three mortalities during the follow-up. We suggest appendicovesicostomy as a safe and lifesaving procedure for long-term management of bladder dysfunction in Wolfram syndrome particularly after progression to blindness.

A total of 164 participants (66.1%) used intermittent catheterization for bladder emptying (48.5% women versus 72.8% men); more paraplegics than tetraplegics (77.2% versus 55.7%). Recommendations given at the Spinal Cord Units were thoroughly followed by persons who had used catheters more than 5 years. Use of incontinence pads were associated with reduced satisfaction of life. The most common method of management of bladder dysfunction is clean intermittent catheterization in Norway. Recommendations were followed more thoroughly by persons who have used intermittent catheterization for more than 5 years. Spinal Cord Units are important source for information and guidance.

    This paper presents an ethically justified approach to the diagnosis and management of progressive dysfunction of health care organizational cultures. We explain the concept of professional integrity in terms of the ethical concept of the cofiduciary responsibility of physicians and health care organizations. We identify the ethical features of a healthy health care organization and the spectrum of progressive dysfunction of organizational cultures from cynical through wonderland and Kafkaesque to postmodern. Physicians should respond to cynical health care organizations by creating moral enclaves of professional integrity for the main purpose of confrontation and reform, to wonderland organizations by strengthening moral enclaves for the main purpose of resisting self-deception, to Kafkaesque organizations by strengthening moral enclaves still further for the main purpose of defending professional integrity (adopting a Machiavellian appearance of virtue as necessary), and to postmodern organizations by creating moral fortresses and, should these fail, quitting.

    PURPOSE: Ileal pouch anal anastomosis is an established option for patients who require total proctocolectomy and restoration of bowel continuity. However, the functional results are not always good and low pouch compliance has been suggested as one possible cause. We aimed to review the results...... of pouch compliance tests over 11 years to assess whether measuring pouch compliance is a useful diagnostic tool to guide management of pouch dysfunction. METHODS: The results of pouch compliance tests performed between 1996 and 2007 together with the details of symptoms, treatments and outcome were...... reviewed. RESULTS: One hundred and forty-one pouch compliance tests were performed. There was no difference in pouch compliance between those with overt pathology (pouchitis, pelvic sepsis or anastomotic stricture) and those with idiopathic pouch dysfunction. In this second group, there was no difference...

    Full Text Available OBJECTIVE: To investigate occurrences of swallowing disorders after ischemic stroke. METHOD: This was a retrospective study on 596 medical files. The inclusion criterion was that the patients needed to have been hospitalized with a diagnosis of ischemic stroke; the exclusion criteria were the presence of associated cardiac problems and hospital stay already more than 14 days. RESULTS: 50.5% were men and 49.5% women; mean age 65.3 years (SD=±11.7 (p<0.001. Among the risk factors, 79.4% had hypertension, 36.7% had diabetes (p<0.001 and 42.7% were smokers. 13.3% of the patients died. Swallowing disorders occurred in 19.6%, among whom 91.5% had mild difficulty and 8.5% had severe difficulty. 87.1% had spontaneous recovery after a mean of 2.4 months. A lesion in the brainstem region occurred in 6.8% (p<0.001. CONCLUSION: Swallowing disorders occurred in almost 20% of the population and most of the difficulty in swallowing found was mild. The predictors for swallowing disorders were older age, diabetes mellitus and lesions in the brainstem region.

    Concurrent chemoradiotherapy (CCRT) for patients with advanced head or neck cancer has become popular as an effective treatment that can preserve their organs and functions after treatment. However, severe dysfunctions as the complications related to CCRT, e.g. dysphagia, sometimes appear in spite of preservation of the affected organs. The aim of the present study is to clarify swallowing function during and after CCRT. Medical records of subjects who received CCRT for treatment of oropharyngeal (21 cases) and hypopharyngeal (19 cases) cancer were retrospectively reviewed for mucositis and dysphagia before, during, and after CCRT using National Cancer Institute-Common Toxicity Criteria (NCI-CTC) version 2.0. Severity of mucositis and dysphagia kept deteriorating during CCRT and 27.5% of the subjects required tube feeding at the end of CCRT. The mucositis improved rapidly after treatment, but severe dysphagia still persisted in 7.5% of the subjects 6 months after CCRT. Planned neck dissections were carried out in 14 patients as additional treatment against lymph node involvement. Although severe dysphagia appeared immediately after surgery, swallowing function returned to preoperative condition within 1 month. The majority of patients who receive CCRT recover their swallowing function within 6 months after CCRT. However, since some patients demonstrate prolonged dysphagia after CCRT, we should receive informed consent from patients about their swallowing condition after CCRT. (author)

    Barium esophagrams performed in 13 children with myelomeningocele demonstrated a variety of swallowing disorders: difficulty in bolus formation, nasopharyngeal reflux, tracheobronchial aspiration. Cricopharyngeal spasm was not identified in this group. Antegrade peristalsis in the distal two-thirds of the esophagus was normal. Gastroesophageal reflux was demonstrated in 8 of the children. Vocal cord paralysis (8/13) and death in early child-hood (6/13) occurred with greater frequency than in the general myelomeningocele population. Correct management of these children may require tracheostomy, gastrostomy, and fundoplication. (orig.)

    Parkinson's disease is a type of chronic neurodegenerative pathology with a typical movement pattern, as well as different, less studied symptoms such as dysphagia. Disease-related disorders in efficacy or safety in the process of swallowing usually lead to malnutrition, dehydration or pneumonias. The aim of this study was identifying and analyzing swallowing disorders in Parkinson's disease. The initial sample consisted of 52 subjects with Parkinson's disease to whom the specific test for dysphagia SDQ was applied. Nineteen participants (36.5%) with some degree of dysphagia in the SDQ test were selected to be evaluated by volume-viscosity clinical exploration method and fiberoptic endoscopic evaluation of swallowing. Disorders in swallowing efficiency and safety were detected in 94.7% of the selected sample. With regards to efficiency, disorders were found in food transport (89.5%), insufficient labial closing (68.4%) and oral residues (47.4%), relating to duration of ingestion. Alterations in security were also observed: pharynx residues (52.7%), coughing (47.4%), penetration (31.64%), aspiration and decrease of SaO 2 (5.3%), relating to the diagnosis of respiratory pathology in the previous year. The SDQ test detected swallowing disorders in 36.5% of the subjects with Parkinson's disease. Disorders in swallowing efficiency and safety were demonstrated in 94.7% of this subset. Disorders of efficiency were more frequent than those of safety, establishing a relationship with greater time in ingestion and the appearance of respiratory pathology and pneumonias.

  2. Voluntary Modulation of Hemodynamic Responses in Swallowing Related Motor Areas: A Near-Infrared Spectroscopy-Based Neurofeedback Study.

    Directory of Open Access Journals (Sweden)

    Silvia Erika Kober

    Full Text Available In the present study, we show for the first time that motor imagery of swallowing, which is defined as the mental imagination of a specific motor act without overt movements by muscular activity, can be successfully used as mental strategy in a neurofeedback training paradigm. Furthermore, we demonstrate its effects on cortical correlates of swallowing function. Therefore, N = 20 healthy young adults were trained to voluntarily increase their hemodynamic response in swallowing related brain areas as assessed with near-infrared spectroscopy (NIRS. During seven training sessions, participants received either feedback of concentration changes in oxygenated hemoglobin (oxy-Hb group, N = 10 or deoxygenated hemoglobin (deoxy-Hb group, N = 10 over the inferior frontal gyrus (IFG during motor imagery of swallowing. Before and after the training, we assessed cortical activation patterns during motor execution and imagery of swallowing. The deoxy-Hb group was able to voluntarily increase deoxy-Hb over the IFG during imagery of swallowing. Furthermore, swallowing related cortical activation patterns were more pronounced during motor execution and imagery after the training compared to the pre-test, indicating cortical reorganization due to neurofeedback training. The oxy-Hb group could neither control oxy-Hb during neurofeedback training nor showed any cortical changes. Hence, successful modulation of deoxy-Hb over swallowing related brain areas led to cortical reorganization and might be useful for future treatments of swallowing dysfunction.

    Hemodialysis access options become complex in long-term treatment for patients with renal disease, while awaiting renal transplantation (RT). Once upper extremity sites are exhausted, lower extremities are used. RT is preferably in the contralateral iliac fossa, rarely ipsilateral. In current literature, RT dysfunction secondary to the hemodynamic effects of an ipsilateral femoral arteriovenous graft (AVG) has been rarely described. To our knowledge, AVG ligation is the only published technique for hemodynamic correction of an ipsilateral AVG. We present a simple, potentially reversible endovascular approach to manage the hemodynamic effects of an AVG, without potentially permanently losing future AVG access. PMID:26899147

    Patients with head and neck cancer have complex swallowing and nutritional concerns. Most patients are malnourished, and treatment modalities within the aerodigestive tract have profound effects on future swallowing and nutrition. The objective of this study is to investigate whether the introduction of fortified soft ice-cream to post-operative head and neck cancer patients would increase compliance with oral-feeding regimes. Using a questionnaire study, an ice-cream machine that produces fortified soft ice-cream was introduced onto our ward, and 30 patients were asked to fill out questionnaires based on their experience in addition to their oral-feeding regime. Results indicate that overall patient satisfaction and compliance with oral-feeding regimes increased: 77% felt that the taste was excellent and also felt that it was easy to eat; 60% felt that it eased the symptoms associated with their symptoms, in particular its cold temperature. We conclude from the results that the inability of patients undergoing multi-modal treatment for upper aerodigestive tract cancer to enjoy normal foods and its effects on their quality of life is underestimated. Providing a food to that is palatable, familiar and acceptable as it is safe and nutritionally sound can increase compliance with oral-feeding regimes. The ice-cream was safe to use in the early post-operative period, especially soothing in patients undergoing upper aerodigestive radiotherapy and high in protein and calorific content. Our practice may have wider benefits, including patients with oral and oropharyngeal infections, the elderly and patients with neurological dysphagia resulting from stroke.

    There are minimal data on radiation doses to infants and children undergoing a modified barium swallow (MBS) study. To document screening times, dose area product (DAP) and effective doses to children undergoing MBS and to determine factors associated with increased screening times and effective dose. Fluoroscopic data (screening time, DAP, kVp) for 90 consecutive MBS studies using pulse fluoroscopy were prospectively recorded; effective dose was calculated and data were analyzed for effects of behavior, number of swallow presentations, swallowing dysfunction and medical problems. Mean effective dose for the entire group was 0.0826 ± 0.0544 mSv, screening time 2.48 ± 0.81 min, and DAP 28.79 ± 41.72 cGy cm 2 . Significant differences were found across three age groups (≤1.0, >1.0-3.0 and >3.0 years) for effective dose (mean 0.1188, 0.0651 and 0.0529 mSv, respectively; P < 0.001), but not for screening time or DAP. Effective dose was correlated with screening time (P 0.007), DAP (P < 0.001), number of swallow presentations (P = 0.007), lower age (P = 0.017), female gender (P = 0.004), and height (P < 0.001). Screening time was correlated with total number of swallow presentations (P < 0.001) and DAP (P < 0.001). Screening times, DAP, effective dose, and child and procedural factors associated with higher effective doses are presented for children undergoing MBS studies. (orig.)

    To evaluate the influence of clinical, treatment- and dose-dependent factors on posttreatment swallowing function after induction chemotherapy and definitive chemoradiotherapy in a group of homogeneously treated laryngopharyngeal cancer patients. From 28 May 2008 to 15 February 2013, 45 patients with borderline inoperable laryngopharyngeal cancer that had responded well to induction chemotherapy were treated with definitive chemoradiotherapy. Median follow-up was 22 months. Swallowing function and clinical data were prospectively analyzed using the EORTC QLQ-C30 questionnaire. Swallowing structures were retrospectively delineated on the original treatment planning CT. Dose-volume histograms were calculated for swallowing structures and D{sub mean}, D{sub max} and V50-V64 values (in 2 Gy increments) were determined for each patient. Tumor volume and infiltration of the swallowing apparatus was defined by CT before induction chemotherapy. Of the 45 patients, 26 (57.8 %) fully regained swallowing function after chemoradiotherapy. A further 12 patients (26.7 %) were able to manage soft, pureed and/or liquid foods; the remaining 7 (15.6 %) were completely dependent on percutaneous endoscopic gastrostomy (PEG). Posttreatment swallowing function was significantly influenced by D{sub mean} to the superior pharyngeal constrictor muscle (PCM, p = 0.041). Correlations between late dysphagia and dose-volume relationships in the superior PCM and soft palate were also observed, which were significant from V60 (p = 0.043) and V58 for the soft palate and superior PCM, respectively. Of the evaluated clinical and tumor-related factors, only alcohol abuse (p = 0.024) had an influence on posttreatment swallowing function. Almost 50 % of patients had deterioration of swallowing function after definitive chemoradiotherapy for laryngopharyngeal cancer. The dose to anatomical structures responsible for swallowing function appears to play a role. Therefore, in selected patients, target

    Swallowing apraxia is characterized by impaired volitional swallowing but relatively preserved reflexive swallowing. Few studies are available on the effectiveness of behavioral therapy and management of the condition. This study aimed to investigate the effect of transcranial direct current stimulation (tDCS) on swallowing apraxia and cortical activation in stroke patients. The study included three inpatients (age 48-70 years; 1 male, 2 females; duration of stroke, 35-55 d) with post-stroke swallowing apraxia and six age-matched healthy subjects (age 45-65 years; 3 males, 3 females). Treatments were divided into two phases: Phase A and Phase B. During Phase A, the inpatients received three weeks of sham tDCS and conventional treatments. During Phase B, these patients received three weeks of anodal tDCS over the bilateral primary sensorimotor cortex (S 1 M 1 ) of swallowing and conventional treatments. Swallowing apraxia assessments were measured in three inpatients before Phase A, before Phase B, and after Phase B. The electroencephalography (EEG) nonlinear index of approximate entropy (ApEn) was calculated for three patients and six healthy subjects. After tDCS, scores of swallowing apraxia assessments increased, and ApEn indices increased in both stimulated and non-stimulated areas. Anodal tDCS might provide a useful means for recovering swallowing apraxia, and the recovery could be related to increased excitability of the swallowing cortex. Further investigations should explore the relationship between lesion size and/or lesion site and the prognosis of swallowing apraxia.

    Reduced swallowing frequency affects secretion management in Parkinson disease (PD). Gum chewing increases saliva flow and swallow frequency. This study uses chewing gum to modify swallow frequency and latency between swallows in patients with PD. 1) Assess the frequency and latency of swallow at baseline (BL), during gum chewing (GC), and post gum chewing (PGC) for participants with PD (stage 2-4) nonsymptomatic for prandial dysphagia; and 2) assess carryover after gum is expectorated. Twenty participants were studied across 3 tasks, each of 5 minutes in duration: BL, GC, and PGC. Respiratory and laryngeal signals were continuously recorded using PowerLab (version 5.5.5; ADI Instruments, Castle Hill, Australia). Frequency and latency of swallow events were calculated. Differences (analysis of variance) are reported for frequency (p Parkinson disease. This study provides Class III evidence that chewing gum increases swallow frequency and decreases latency of swallowing in an experiment in patients with stage 2 to 4 Parkinson disease who are nonsymptomatic for significant prandial dysphagia.

    This epidemiological investigation examined the prevalence, risk factors, and quality-of-life effects of swallowing disorders in Sjögren's syndrome (SS). One hundred and one individuals with primary or secondary SS (94 females, 7 males; mean age 59.4, SD = 14.1) were interviewed regarding the presence, nature, and impact of swallowing disorders and symptoms. Associations among swallowing disorders and symptoms, select medical and social history factors, SS disease severity, and the M.D. Anderson Dysphagia Inventory (MDADI) and Short Form 36 Health Survey (SF-36) were examined. The prevalence of a current self-reported swallowing disorder was 64.4 %. SS disease severity was the strongest predictor of swallowing disorders, including significant associations with the following swallow symptoms: taking smaller bites, thick mucus in the throat, difficulty placing food in the mouth, and wheezing while eating (p esophageal reflux, current exposure to secondary tobacco smoke, frequent neck or throat tension, frequent throat clearing, chronic post-nasal drip, and stomach or duodenal ulcers. Swallowing disorders did not differ on the basis of primary or secondary SS. Swallowing disorders and specific swallowing symptoms were uniquely associated with reduced quality of life. Among those with swallowing disorders, 42 % sought treatment, with approximately half reporting improvement. Patient-perceived swallowing disorders are relatively common in SS and increase with disease severity. Specific swallowing symptoms uniquely and significantly reduce swallow and health-related quality of life, indicating the need for increased identification and management of dysphagia in this population.

    Full Text Available ABSTRACT BACKGROUND: Dysphagia is described as a complaint in 32% of patients with laryngitis. OBJECTIVE: The objective of this investigation was to evaluate oral and pharyngeal transit of patients with laryngitis, with the hypothesis that alteration in oral-pharyngeal bolus transit may be involved with dysphagia. METHODS: Videofluoroscopic evaluation of the swallowing of liquid, paste and solid boluses was performed in 21 patients with laryngitis, 10 of them with dysphagia, and 21 normal volunteers of the same age and sex. Two swallows of 5 mL liquid bolus, two swallows of 5 mL paste bolus and two swallows of a solid bolus were evaluated in a random sequence. The liquid bolus was 100% liquid barium sulfate and the paste bolus was prepared with 50 mL of liquid barium and 4 g of food thickener (starch and maltodextrin. The solid bolus was a soft 2.2 g cookie coated with liquid barium. Durations of oral preparation, oral transit, pharyngeal transit, pharyngeal clearance, upper esophageal sphincter opening, hyoid movement and oral-pharyngeal transit were measured. All patients performed 24-hour distal esophageal pH evaluation previous to videofluoroscopy. RESULTS: The evaluation of 24-hour distal esophageal pH showed abnormal gastroesophageal acid reflux in 10 patients. Patients showed longer oral preparation for paste bolus and a faster oral transit time for solid bolus than normal volunteers. Patients with laryngitis and dysphagia had longer preparation for paste and solid boluses, and a faster oral transit time with liquid, paste and solid boluses. CONCLUSION: A longer oral preparation for paste and solid boluses and a faster transit through the mouth are associated with dysphagia in patients with laryngitis.

Durations of oral preparation, oral transit, pharyngeal transit, pharyngeal clearance, upper esophageal sphincter opening, hyoid movement and oral-pharyngeal transit were measured. All patients performed 24-hour distal esophageal pH evaluation previous to videofluoroscopy. The evaluation of 24-hour distal esophageal pH showed abnormal gastroesophageal acid reflux in 10 patients. Patients showed longer oral preparation for paste bolus and a faster oral transit time for solid bolus than normal volunteers. Patients with laryngitis and dysphagia had longer preparation for paste and solid boluses, and a faster oral transit time with liquid, paste and solid boluses. A longer oral preparation for paste and solid boluses and a faster transit through the mouth are associated with dysphagia in patients with laryngitis.

    Children with neurological disabilities frequently have problems with feeding and swallowing. Such problems have a significant impact on the health and well-being of these children and their families. The primary aims in the rehabilitation of pediatric feeding and swallowing disorders are focused on supporting growth, nutrition and hydration, the development of feeding activities, and ensuring safe swallowing with the aim of preventing choking and aspiration pneumonia. Pediatric feeding and swallowing disorders can be divided into four groups: transient, developmental, chronic or progressive.This article provides an overview of the available literature about the rehabilitation of feeding and swallowing disorders in infants and children. Principles of motor control, motor learning and neuroplasticity are discussed for the four groups of children with feeding and swallowing disorders.

    Patients with left ventricular diastolic dysfunction (LVDD) are at increased risk of postoperative adverse events. The primary aim of this study was to evaluate the safety and feasibility of using echocardiography-guided hemodynamic management (EGHEM) during surgery in subjects with LVDD compared to conventional management. The feasibility of using echocardiography to direct a treatment algorithm and clinical outcomes were compared for safety between groups. Subjects were screened for LVDD by preoperative transthoracic echocardiography (TTE) and randomized to the conventional or EGHEM group. Subjects in EGHEM received hemodynamic management based on left ventricular filling patterns on transesophageal echocardiography (TEE). Primary outcomes measured were the feasibility to obtain TEE images and follow a TEE-based treatment algorithm. Safety outcomes also compared the following clinical differences between groups: length of hospitalization, incidence of atrial fibrillation, congestive heart failure (CHF), myocardial infarction, cerebrovascular accident, transient ischemic attack and renal failure measured 30 days postoperatively. Population consisted of 28 surgical subjects (14 in conventional group and 14 in EGHEM group). Mean subject age was 73.4 ± 6.7 years (36% male) in conventional group and 65.9 ± 14.4 years (36% male) in EGHEM group. Procedures included orthopedic (conventional = 29%, EGHEM 36%), general (conventional = 50%, EGHEM = 36%), vascular (conventional = 7%, EGHEM = 21%), and thoracic (conventional = 14%, EGHEM = 7%). There was no statistically significant difference in adverse clinical events between the 2 groups. The EGHEM group had less CHF, atrial fibrillation, and shorter length of stay. Echocardiography-guided hemodynamic management of patients with LVDD during surgery is feasible and may be a safe alternative to conventional management. © 2014, Wiley Periodicals, Inc.

    The purpose of this study was to measure the tongue and mandible positions and displacements in relation to the maxilla in the midsagittal plane to characterize the different saliva swallowing patterns by recording their kinematics. A 2D electromagnetic articulograph using four transducer coils, three attached to the upper surface of the tongue midline plus one attached to the chin anterior part allowed continuous evaluation of tongue and chin movements in twelve young adults in good general health. During 170 s sequences recorded at a frequency of 100 Hz, subjects were at rest, silently reading a text they had chosen. The subjects were free to swallow during the sequence. Deglutition of accumulated saliva was analysed after averaging all values obtained during successive 250 ms periods. We identified three elementary swallowing patterns. Mean duration of tongue-mandible movements were 1·51 ± 0·17 s, 1·63 ± 0·14 s and 2·00 ± 0·08 s for the first, second and third patterns respectively. In the light of other studies based on intra-oral pressure recordings, our results help to understand the tongue-mandible coupling behaviours involved in managing an in-mouth saliva bolus during the three elementary swallowing patterns identified. © 2014 John Wiley & Sons Ltd.

    Behavioural performance of tablet swallowing was evaluated with different tablet conditions in terms of size, number and surface coating. Four different types of tablets were prepared: small or large, and with or without a surface coating. Fourteen normal male adults were instructed to swallow the prepared tablets with 15 ml of water. The number of tablets in one trial was changed from one to three. To evaluate swallowing and tablet transport, electromyographic activity was recorded in the left suprahyoid muscles, and videofluorographic images were examined. All tablet conditions (size, number and surface coating) affected the swallowing performance in terms of total number of swallows, electromyographic burst patterns and location of remaining tablets. Increases in the size and number of tablets increased the number of swallows and electromyographic burst area and duration. In addition, all of these parameters increased while swallowing tablets without a coating compared with tablets with a coating. Location of the remaining tablets was mainly within the mouth. This study only clarified the normal pattern of tablet swallowing under several conditions in healthy subjects, but the results may facilitate comprehensive evaluation and treatment planning in terms of administering medication to dysphagic patients. © 2013 Royal Pharmaceutical Society.

    Parkinson disease (PD) is a complex, progressive, neurodegenerative disorder that leads to a wide range of deficits including fine and gross sensorimotor impairment, autonomic dysfunction, mood disorders, and cognitive decline. Traditionally, the focus for diagnosis and treatment has been on sensorimotor impairment related to dopamine depletion. It is now widely recognized, however, that PD-related pathology affects multiple central nervous system neurotransmitters and pathways. Communication and swallowing functions can be impaired even in the early stages, significantly affecting health and quality of life. The purpose of this article is to review the literature on early intervention for communication and swallowing impairment in PD. Overarching themes were that (1) studies and interpretation of data from studies in early PD are limited; (2) best therapy practices have not been established, in part due to the heterogeneous nature of PD; and (3) as communication and swallowing problems are pervasive in PD, further treatment research is essential.

    Oropharyngeal dysphagia (OD) affects older and neurological patients, causing malnutrition and dehydration and increasing the risk for aspiration pneumonia. There is evidence that sensory deficits in those populations are closely related to swallowing disorders, and several research groups are developing new therapies based on sensory stimulation of this area. More information on the sensory innervation participating in the swallow response is needed to better understand the pathophysiology of OD and to develop new treatments. This review focuses on the sensory innervation of the human oropharynx and larynx in healthy people compared with patients with swallowing disorders in order to unravel the abnormalities that may lead to the loss of sensitivity in patients with OD. We also hypothesize the pathway through which active sensory-enhancement treatments may elicit their therapeutic effect on patients with swallowing dysfunctions. As far as we know, this is the first time a review covers the anatomy, histology, ultrastructure, and molecular biology of the sensory innervation of the swallowing function. © 2016 New York Academy of Sciences.

    Full Text Available Denture ingestion or aspiration is a problem requiring awareness of different specialists including dentists, surgeons, otolaryngologists, and anesthesiologists for prevention, early diagnosis and adequate treatment. Complications of swallowed dentures include hollow viscous necrosis, perforation, and penetration to neighbouring organs leading to fistulae, bleeding and obstruction. Here, we present the case of a 65 year old female patient who swallowed the denture, which was detected by barium swallow and removed by endoscopy. Hence, the management of swallowed denture needs a multidisciplinary approach with the help of a dentist, otolaryngologist and anesthesiologists. Dentists should recommend patients to visit them for planned check ups or revisit them in case of denture dislodgement or loosening as soon as possible to prevent such life threatening events.

  5. Comparison of Masticatory and Swallowing Functional Outcomes in Surgically and Prosthetically Rehabilitated Maxillectomy Patients.

    This study compared masticatory and swallowing functional outcomes in maxillectomy patients who underwent surgical and prosthetic rehabilitation or prosthetic rehabilitation only following surgical resection. This comparative cross-sectional study involved 20 maxillectomy patients and compared their masticatory and swallowing functions following combined surgical and prosthodontic management vs an exclusively prosthodontic approach. Masticatory performance was measured by an originally modified sieve method using hydrocolloid material, and video fluoroscopic examination was employed for swallowing assessments. Masticatory performance was significantly better in the patient group treated with flaps and removable denture prostheses compared to patients treated with obturator prosthesis alone. Swallowing outcomes were comparable in both groups. Flap reconstruction followed by an obturator prosthesis seems to be a preferable option when planning for functional rehabilitation in maxillectomy patients. Further research is needed to substantiate the functional outcomes noted in this study.

    Full Text Available Swallowing is a complex process consisting in transporting food from mouth to the stomach; it involves voluntary and reflex activity of more than 30 nerves and muscles, requiring complex neuromuscular coordination and brainstem and cortical centers for controle. Dysphagia is defined as a alteration in the swallowing process, which cause difficulty in transporting saliva and aliments from the mouth trough the pharynx and esophagus into the stomach . It is a frequent symptom, affecting especially old people, people with neurological diseases, cancers of head and neck or severe reflux . Dysphagia can result from a wide variety of functional or structural deficits of the oral cavity, pharynx, larynx or esophagus, which could e caused by neurological conditions. Dysphagia carries serious health risks: malnutrition, dehydration, increase risk of infections. Effective dysphagia management requires an interdisciplinary approach; the goal of rehabilitation is to identify and treat abnormalities of swallowing while maintaining safe and efficient nutrition.

    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.

    Full Text Available Buccal carcinoma is one of the most common malignant neoplasms among all oral cancers in India. Understanding the role of speech language pathologists (SLPs in the domains of evaluation and management strategies of this condition is limited, especially in the Indian context. This is a case report of a young adult with recurrent squamous cell carcinoma of the buccal mucosa with no deleterious habits usually associated with buccal mucosa carcinoma. Following composite resection, pectoralis major myocutaneous flap reconstruction, he developed severe oral dysphagia and demonstrated unintelligible speech. This case report focuses on the issues of swallowing and speech deficits in buccal mucosa carcinoma that need to be addressed by SLPs, and the outcomes of speech and swallowing rehabilitation and prognostic issues.

    BACKGROUND Bowel dysfunction is a known complication of colorectal cancer (CRC) surgery. Poor bowel control has a detrimental impact on survivors’ health-related quality of life (HRQOL). This analysis describes the dietary and behavioral adjustments used by CRC survivors to manage bowel dysfunction and compares adjustments used by survivors with permanent ostomy to those with anastomosis. METHODS This mixed-methods analysis included pooled data from several studies that assessed HRQOL in CRC survivors. In all studies, CRC survivors with or without permanent ostomies (N=856) were surveyed using the City of Hope Quality of Life Colorectal Cancer tool. Dietary adjustments were compared by ostomy status and by overall HRQOL score (high versus low). Qualitative data from 13 focus groups and 30 interviews were analyzed to explore specific strategies used by survivors to manage bowel dysfunction. RESULTS CRC survivors made substantial, permanent dietary and behavioral adjustments after surgery, regardless of ostomy status. Survivors who took longer after surgery to become comfortable with their diet or regain their appetite were more likely to report worse HRQOL. Adjustments to control bowel function were divided into four major strategies: dietary adjustments, behavioral adjustments, exercise, and medication use. CONCLUSIONS CRC survivors struggled with unpredictable bowel function and may fail to find a set of management strategies to achieve regularity. Understanding the myriad adjustments used by CRC survivors may lead to evidence-based interventions to foster positive adjustments after surgery and through long-term survivorship. PMID:26159443

    Full Text Available Abstract Background Various functional resonance imaging, magnetoencephalographic and lesion studies suggest the involvement of the insular cortex in the control of swallowing. However, the exact location of insular activation during swallowing and its functional significance remain unclear. Case presentation Invasive electroencephalographic monitoring was performed in a 24-year-old man with medically intractable stereotyped nocturnal hypermotor seizures due to a ganglioglioma. During stimulation of the right inferior posterior insular cortex with depth electrodes the patient spontaneously reported a perception of a "stutter in swallowing". Stimulation of the inferior posterior insular cortex at highest intensity (4 mA was also associated with irregular and delayed swallows. Swallowing was not impaired during stimulation of the superior posterior insular cortex, regardless of stimulation intensity. Conclusions These results indicate that the right inferior posterior insular cortex is involved in the neural circuitry underlying the control of swallowing.

    Introduction Approximately 60 000 prosthetic valves are implanted annually in the USA. The risk of prosthesis dysfunction ranges from 0.1% to 4% per year. Prosthesis valve dysfunction is usually caused by a thrombus obstructing the prosthetic discs. However, 10% of prosthetic valves are dysfunctional due to pannus formation, and 12% of prostheses are damaged by both fibrinous and thrombotic components. The authors present two patients with dysfunctional aortic prostheses who were referred for cardiac surgery. Different surgical solutions were used in the treatment of each case. Case study 1 The first patient was a 71-year-old woman whose medical history included arterial hypertension, stable coronary artery disease, diabetes mellitus, chronic obstructive pulmonary disease (COPD), and hypercholesterolemia; she had previously undergone left-sided mastectomy and radiotherapy. The patient was admitted to the Cardiac Surgery Department due to aortic prosthesis dysfunction. Transthoracic echocardiography revealed complete obstruction of one disc and a severe reduction in the mobility of the second. The mean transvalvular gradient was very high. During the operation, pannus covering the discs’ surface was found. A biological aortic prosthesis was reimplanted without complications. Case study 2 The second patient was an 87-year-old woman with arterial hypertension, persistent atrial fibrillation, and COPD, whose past medical history included gastric ulcer disease and ischemic stroke. As in the case of the first patient, she was admitted due to valvular prosthesis dysfunction. Preoperative transthoracic echocardiography revealed an obstruction of the posterior prosthetic disc and significant aortic regurgitation. Transesophageal echocardiography and fluoroscopy confirmed the prosthetic dysfunction. During the operation, a thrombus growing around a minor pannus was found. The thrombus and pannus were removed, and normal functionality of the prosthetic valve was restored

    1996-02-01

    Videofluoroscopic swallowing examinations of 3 patients with dysphagia were reviewed independently by 10 speech-language pathologists. Prior to viewing each video, clinicians were provided with information about the patient's history, the results of a bedside swallow examination, and oral-facial and oral motor control examinations. Clinicians completed a swallowing observation protocol as they viewed each video. They then recommended, from a list of treatment strategies, intervention techniques that would be most appropriate for each patient. Interjudge agreement was calculated by determining how many clinicians observed a given swallowing event or deficit, and how many recommended a given treatment strategy. Results suggest that the level of interjudge agreement for videofluoroscopic evaluations is not encouragingly high.

    This paper evaluates pharyngeal and esophageal swallowing disorders in Parkinson disease. Clinical, videofluorographic and manometric investigations were performed prospectively in 12 control subjects (eight men and four women; mean age, 60 years) and 21 patients with Parkinson disease (10 men and 11 women; mean age, 64 years) to study oral, pharyngeal, and esophageal motoricity. Seventeen patients (81%) complained of swallowing disorders: buccal bolus retention (48%), split swallowing (48%), and saliva buccal outflow (57%). Videofluorography was normal in control subjects and in eight patients (40%). Abnormal findings included vallecular and piriform recesses retention (60%) and split swallowing (35%). Manometry showed a nonperistaltic pharyngeal motoricity with simultaneous contraction in 14 patients (67%) and incomplete upper esophageal sphincter relaxation in three patients (14%). Body esophageal motoricity disorders indicated achalasia in five patients (24%), diffuse esophageal spasm in six (29%), and nonspecific esophageal motility disorder in five (24%)

    During ornithological studies in the provinces of Jujuy, Salta, and San Juan, we recorded the Andean Swallow Orochelidon andecola at 40 localities. These are the first records in Argentina, and also represent the southernmost for the species. Some of these localities are up to 1500 m lower than the previously known elevational limit (now 800 masl), and up to 1100 km southwards. This is a relatively poorly known swallow, and we present novel natural history data. We found evidence of breeding ...

    1990-01-01

    Fifty-one patients with systemic sclerosis (scleroderma) were studied by means of videofluoroscopy in order to evaluate the abnormalities in the oral-pharyngeal and esophageal phases of deglutition and to correlate the radiological patterns with the clinical features of the disease. Thirteen patients (25.5%) exhibited swallowing disorders such as oral leakage, retention, penetration, mild or moderate aspiration and abnormal upper esophageal sphincter behavior. These dysfunctions were more evident in patients with esophageal motility abnormalities. A normal radiological pattern in the esophagus was not associated with swallowing alterations. Remarkably, patients with oral-pharyngeal disorders had a higher incidence of lung diseases. Forty-five patients (88%) exhibited disorders of the esophageal phase of deglutition, such as mild or severe motility abnormalities or hiatal hernia, gastro-esophageal reflux, reflux esophagitis, and stricture. Radiological findings in the esophagus can be abnormal in the early stages of the disease. On the other hand, the radiological pattern of esophageal motility can be occasionally negative in advanced or extensive disease. This indicates a discrepancy between clinical symptoms and radiological picture of the esophagus. The radiological examination of the oral-pharyngeal and esophageal phases of deglutition is important in patients with scleroderma in order to evaluate visceral involvement, motility disorders, and risk of aspiration. Such radiological information can be useful in preventing esophagitis and pulmonary complications

    Dysphagia can cause serious challenges to both physical and mental health. Aspiration due to dysphagia is a major health risk that could cause pneumonia and even death. The videofluoroscopic swallow study (VFSS), which is considered the gold standard for the diagnosis of dysphagia, is not widely available, expensive and causes exposure to radiation. The screening tests used for dysphagia need to be carried out by trained staff, and the evaluations are usually non-quantifiable. This paper investigates the development of the Swallowscope, a smartphone-based device and a feasible real-time swallowing sound-processing algorithm for the automatic screening, quantitative evaluation, and the visualisation of swallowing ability. The device can be used during activities of daily life with minimal intervention, making it potentially more capable of capturing aspirations and risky swallow patterns through the continuous monitoring. It also consists of a cloud-based system for the server-side analyzing and automatic sharing of the swallowing sound. The real-time algorithm we developed for the detection of dry and water swallows is based on a template matching approach. We analyzed the wavelet transformation-based spectral characteristics and the temporal characteristics of simultaneous synchronised VFSS and swallowing sound recordings of 25% barium mixed 3-ml water swallows of 70 subjects and the dry or saliva swallowing sound of 15 healthy subjects to establish the parameters of the template. With this algorithm, we achieved an overall detection accuracy of 79.3% (standard error: 4.2%) for the 92 water swallows; and a precision of 83.7% (range: 66.6%–100%) and a recall of 93.9% (range: 72.7%–100%) for the 71 episodes of dry swallows.

We analyzed the wavelet transformation-based spectral characteristics and the temporal characteristics of simultaneous synchronised VFSS and swallowing sound recordings of 25% barium mixed 3-ml water swallows of 70 subjects and the dry or saliva swallowing sound of 15 healthy subjects to establish the parameters of the template. With this algorithm, we achieved an overall detection accuracy of 79.3% (standard error: 4.2%) for the 92 water swallows; and a precision of 83.7% (range: 66.6%-100%) and a recall of 93.9% (range: 72.7%-100%) for the 71 episodes of dry swallows.

    It is increasingly recognized that in children swallowed multiple magnets cause considerable damage to the gastrointestinal tract. To emphasize that complications from swallowed magnets are extensive worldwide and throughout childhood. The author surveyed radiologists and researched cases of magnet swallowing in the literature and documented age and gender, numbers of magnets, nature of the magnets, reasons for swallowing, and clinical course. A total of 128 instances of magnet swallowing were identified, one fatal. Cases from 21 countries were found. Magnet swallowing occurred throughout childhood, with most children older than 3 years of age. Numbers of swallowed magnets ranged up to 100. Twelve children were known to be autistic. Many reasons were given for swallowing magnets, and a wide range of gastrointestinal damage was encountered. Considerable delay before seeking medical assistance was frequent, as was delay before obtaining radiographs or US imaging. Damage from swallowing multiple magnets is a considerable worldwide problem. More educational and preventative measures are needed. (orig.)

    Pharyngeal electrical stimulation (PEStim) has been found to facilitate voluntary swallowing. This study investigated how PEStim contributed to modulation of swallowing function in 15 healthy humans. In the involuntary swallowing test, water was injected onto the pharynx at 0.05 ml/s and the onset latency of the first swallow was measured. In the voluntary swallowing test, subjects swallowed their own saliva as quickly as possible for 30 s and the number of swallows was counted. Voluntary and involuntary swallowing was evaluated before (baseline), immediately after, and every 10 min after 10-min PEStim for 60 min. A voluntary swallowing test with simultaneous 30-s PEStim was also conducted before and 60 min after 10-min PEStim. The number of voluntary swallows with simultaneous PEStim significantly increased over 60 min after 10-min PEStim compared with the baseline. The onset latency of the first swallow in the involuntary swallowing test was not affected by 10-min PEStim. The results suggest that PEStim may have a long-term facilitatory effect on the initiation of voluntary swallowing in healthy humans, but not on peripherally-evoked swallowing. The physiological implications of this modulation are discussed.

    Congestive heart failure (CHF) has become a large social burden in modern Western society, with very high morbidity and mortality and extremely large financial costs. The largest cause of CHF is coronary heart disease, with ventricular dysfunction that may or may not be reversible by revascularization. Thus, evaluation of the viable myocardial tissue in patients with ischemic left ventricular (LV) dysfunction has important clinical and therapeutic implications. Furthermore, since patients with ventricular dysfunction are at higher operative risk, cardiologists and cardiac surgeons are commonly faced with issues regarding the balance between the potential risk vs benefit of revascularization procedures. Cardiac nuclear imaging [myocardial perfusion SPECT (MPS) and positron emission tomography (PET)] provide objective information that augments standard clinical and angiographic assessments of patients with ventricular dysfunction with respect to diagnosis (etiology), prognosis, and potential benefit from intervention. Development of the technology and methodology of gated MPS, now the routine method for MPS, allows assessment of the extent and severity of inducible ischemia as well as hypoperfused but viable myocardium, and also provides measurements of LV ejection fraction, regional wall motion, LV volume measurements, diastolic function and LV geometry. With PET, myocardial metabolism and blood flow reserve can be added to the measurements provided by nuclear cardiology procedures. This paper provides insight into the current evidence regarding settings in which nuclear cardiac imaging procedures are helpful in assessment of patients in the setting of coronary artery disease with severe LV dysfunction. A risk-benefit approach to MPS results is proposed, with principal focus on identifying patients at risk for major cardiac events who may benefit from myocardial revascularization.

    2016-01-01

    Mastication and swallowing are the first stage of digestion involving several motor processes such as food intake, intra-oral food transport, bolus formation and chewing and swallowing reflex. These complicated motor functions are accomplished by the well-coordinated activities in the jaw, hyoid, tongue, facial and pharyngeal muscles. Although the basic activity patterns of these movements are controlled by the brainstem pattern generators, these movements generate various peripheral sensory inputs. Among the sensory inputs, it is well-known that somatic sensory inputs play important roles in reflexively modulating the movements so that the final motor outputs fit the environmental demand. However, little is known about the effects of chemical sensory inputs such as taste and olfaction originating from the ingested foods by these movements. A possible reason could be raised that cognition of the chemical sensory inputs at the higher brain also influences the movements, so it is difficult to discuss the neural mechanisms underlying the observed effect. In this review, we focus on the effects of chemical sensory inputs on the masticatory movements and initiation of swallowing. We first summarize chemical sensory inputs occurring during mastication and swallowing, and their receptive mechanisms. In addition, we will introduce the effect of application of monosodium L-glutamate (MSG) solution as an umami taste to the oropharynx on the swallow initiation which is involuntary controlled and the possible neural mechanisms underlying this effect is discussed.

  8. Development of a system to monitor laryngeal movement during swallowing using a bend sensor.

    Full Text Available BACKGROUND: Swallowing dysfunction (also known as dysphagia, which results in a deterioration of nutritional intake, slows rehabilitation and causes aspiration pneumonia, is very common following neurological impairments. Although videofluorographic (VF examination is widely used for detecting aspiration, an objective and non-invasive method for assessing swallowing function has yet to be established because of a lack of adequate devices and protocols. In this paper, a bend sensor whose resistance is altered by bending was introduced to monitor swallowing-related laryngeal movement. METHODS: Six healthy male volunteers were recruited in the present study. Specific time points on the signal waveform produced by the bend sensor were defined to describe laryngeal movement by differential analysis. Additionally, the physiological significance of the obtained waveform was confirmed by analyzing the sequential correlations between the signal waveform from the bend sensor and hyoid bone kinetics simultaneously recorded by VF. RESULTS: Seven time points were successfully defined on the signal waveform to reference laryngeal movement. Each time point was well correlated with certain VF events, with evidence of no significant time lags, and there were positive correlations between waveform time points and matched VF events. Furthermore, obvious similarities were noticed between the duration of each phase on the signal waveform and the duration of the matched hyoid bone activity. CONCLUSIONS: The present monitoring system using a bend sensor might be useful for observing the temporal aspects of laryngeal movement during swallowing, and it was well coordinated with hyoid bone movement.

    Surgical treatment of anatomic bladder outlet obstruction (BOO) may be indicated in males with neurogenic bladder dysfunction. A bothersome complication after surgery is urinary incontinence. To identify the optimal practice in the surgical treatment of anatomic BOO in males with neurogenic bladder dysfunction, due to multiple sclerosis, Parkinson disease, spinal cord injury (SCI), spina bifida, or cerebrovascular accident (CVA). A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Medline, Embase, Cochrane controlled trial databases, Web of Science, and Google Scholar were searched for publications until January 2017. A total of 930 abstracts were screened. Eight studies were included. The types of anatomic BOO discussed were benign prostate obstruction, urethral stricture, and bladder neck sclerosis. The identified surgical treatments were transurethral resection of the prostate (TURP) in patients with Parkinson, CVA or SCI, endoscopic treatment of urethral stricture by laser ablation or urethrotomy (mainly in SCI patients), and bladder neck resection (BNR) in SCI patients. The outcome of TURP may be highly variable, and includes persistent or de novo urinary incontinence, regained normal micturition control, and urinary continence. Good results were seen in BNR and endoscopic urethrotomy studies. Laser ablation and cold knife urethrotomy resulted in restarting intermittent catheterization or adequate voiding. Overall, a high risk of bias was found. This systematic review provides an overview of the current literature on the outcome of several surgical approaches of different types of anatomic BOO in males with neurogenic bladder dysfunction. Identifying the optimal practice was impossible due to limited availability of high-quality studies. The outcome of several surgical approaches in males with neurogenic bladder dysfunction with benign prostate obstruction, urethral stricture

    Abstract Background: Job-related burnout and distress are adverse stress responses which affect individuals in their occupational environment. This study aimed at investigating the effect of a rational-emotive stress management program on job burnout and dysfunctional distress among special education teachers in Nigeria. Methods: A pretest–posttest randomized control group design was used. The participants in the study were 54 special education teachers. Data were collected using self-report questionnaires. Participants were allocated to either the treatment group (n = 28 [59.1%]) or the waitlist control group (n = 26 [48.1%]), respectively. A rational-emotive stress management manual was used to deliver the intervention. We statistically analyzed the data collected at three-time points with repeated-measures analysis of variance. Results: At baseline, the job-related burnout symptoms and distress scores of participants were high. However, an intention-to-treat analysis showed that the rational-emotive stress management intervention program was efficacious in reducing the levels of job-related burnout symptoms and dysfunctional distress among participants assigned to the treatment group, compared to a waitlisted group at post-treatment and follow-up meetings. Conclusion: Our study demonstrates the effectiveness of a rational-emotive stress management intervention in reducing the level of job-related burnout and distress in a sample of special education teachers in Nigeria. Occupational health counsellors and other clinicians with sufficient knowledge of rational-emotive behavior therapy framework are urged to employ this approach in assisting other employees in managing job burnout symptoms, and distress.

    Full Text Available BackgroundEructation is a physiologic event which allows gastric venting of swallowed air and most of the time is not perceived as a symptom. This is called gastric belching. Supragastric belching occurs when swallowed air does not reach the stomach and returns by mouth a short time after swallowing. This situation may cause discomfort, life limitations and problems in daily life.ObjectiveOur objective in this investigation was to evaluate if gum chewing increases the frequency of gastric and/or supragastric belches.MethodsEsophageal transit of liquid and gas was evaluated by impedance measurement in 16 patients with complaint of troublesome belching and in 15 controls. The Rome III criteria were used in the diagnosis of troublesome belching. The esophageal transit of liquid and gas was measured at 5 cm, 10 cm, 15 cm and 20 cm from the lower esophageal sphincter. The subjects were evaluated for 1 hour which was divided into three 20-minute periods: (1 while sitting for a 20-minute base period; (2 after the ingestion of yogurt (200 mL, 190 kcal, in which the subjects were evaluated while chewing or not chewing gum; (3 final 20-minute period in which the subjects then inverted the task of chewing or not chewing gum. In gastric belch, the air flowed from the stomach through the esophagus in oral direction and in supragastric belch the air entered the esophagus rapidly from proximal and was expulsed almost immediately in oral direction. Air swallows were characterized by an increase of at least 50% of basal impedance and saliva swallow by a decrease of at least 50% of basal impedance, that progress from proximal to distal esophagus.ResultsIn base period, air swallowing was more frequent in patients than in controls and saliva swallowing was more frequent in controls than in patients. There was no difference between the medians of controls and patients in the number of gastric belches and supragastric belches. In six patients, supragastric belches

    Dysphagia is a well-known complication of acute stroke. Given the complexity of cerebral swallowing control it is still difficult to predict which patients are likely to develop swallowing dysfunction based on their neuroimaging. In Part 2 of a comprehensive voxel-based imaging study, whether the location of a stroke lesion can be correlated with further dysfunctional swallowing patterns, pulmonary protective reflexes and pneumonia was evaluated. In all, 200 acute stroke cases were investigated applying flexible endoscopic evaluation of swallowing within 96 h from admission. Lesions were mapped using patients' computed tomography/magnetic resonance images and these were registered to a standard space. The percentage of lesioned volume of 137 anatomically defined brain regions was determined on a voxel basis (FSL5.0). Region-specific odds ratios (ORs) were calculated with respect to the presence of oropharyngeal residue, delayed swallow response, insufficient cough reflex and occurrence of pneumonia during hospital stay. Colour-coded lesion location maps of brain regions with significant ORs were created (P pneumonia, but substantial overlap between the last two conditions. This study gives new insights on the cortical representation of single components of swallowing and airway protection behaviours. The lesion model may help to risk-stratify patients for dysphagia and pneumonia based on their brain scan. © 2017 EAN.

    A significant proportion of healthy seniors report difficulty swallowing, thought to result from age-related decline in muscle bulk/function. Effortful Swallowing (ES) is used both as a compensatory maneuver to improve pharyngeal propulsion/clearance and has been proposed as an exercise to improve pharyngeal strength. This study sought to quantify the immediate kinematic, temporal, and functional changes during an ES maneuver to quantify its exercise potential to combat age-related changes in swallowing. Videofluoroscopy data were collected from 44 healthy seniors (21 male) over 65 years old (mean = 76.9, SD = 7.1). Each participant swallowed six 5 ml boluses of Varibar nectar-thick liquids: three with regular effort and three using ES. Individual swallows (n = 260) were measured on pharyngeal constriction, pharyngeal shortening, laryngeal closure duration, hyoid movement duration, UES opening duration, stage transition duration, pharyngeal transit time, pharyngeal response duration, Normalized Residue Ratio Scale (NRRS), and the Penetration-Aspiration Scale (PAS). Non-parametric Wilcoxon Rank Sum for repeated measures tested the effect of ES on each outcome. Exact p-values were calculated based on permutation methods, individual p values < 0.008 was deemed to be significant. The ES maneuver significantly prolonged all temporal variables. While we found no significant differences for pharyngeal constriction, significantly less (i.e., worse) pharyngeal shortening was observed in ES condition compared with regular effort swallows. Further, significantly worse pyriform sinus residue (NRRSv) was observed in the ES condition. No differences between ES and regular effort swallows were noted for pharyngeal constriction, NRRSv or PAS. We speculate that these negative manifestations of worse kinematics (less pharyngeal shortening) and function (increase in NRRSp) may be the result of forced volitional manipulation of swallowing in the ES condition in an otherwise

    Bowel dysfunction results in a major lifestyle disruption for many patients with severe central neurologic disease. Percutaneous endoscopic sigmoid colostomy for irrigation (PESCI) allows antegrade irrigation of the distal large bowel for the management of both incontinence and constipation. This study prospectively assessed the safety and efficacy of PESCI. A PESCI tube was placed endoscopically in the sigmoid colon of 25 patients to allow antegrade irrigation. Control of constipation and fecal incontinence was improved for 21 (84%) of the 25 patients. These patients were followed up for 6-83 months (mean, 43 months), with long-term success for 19 (90%) of the patients. No PESCI had to be removed for technical reasons or for PESCI complications. Late removal of the PESCI was necessary for 2 of the 21 patients. A modified St. Marks Fecal Incontinence Score to assess bowel function before and after PESCI showed a highly significant improvement (P irrigation in the management bowel dysfunction for selected patients with central neurologic disease. A successful PESCI is very likely to continue functioning satisfactorily for a long time without technical problems or local complications.

    Swallowing is an essential function of the upper alimentary tract. It is highly complex, requiring precise coordination of numerous nerves and muscles of the oral cavity, pharynx, larynx, and esophagus. Swallowing is integrated with other physiologic functions, including mastication and respiration. Impairments of swallowing may result from many different structural or physiologic disorders. Little is currently known about the direct effects of pollution on swallowing. Structures critical to swallowing, however, are vulnerable to damage by environmental hazards such as exposure to ionizing radiation or intake of toxins by ingestion or inhalation. The relationship of swallowing to environmental lung disease is an area of particular interest because impaired swallowing may result in aspiration of food particles into the lung, and because pollutants may hamper airway defense mechanisms. In this article, we discuss the possible impact of selected environmental agents on swallowing and suggest future directions for research.26 references.

    Besides hypogonadism, other endocrine disorders have been associated with male sexual dysfunction (MSD). To review the role of the pituitary hormone prolactin (PRL), growth hormone (GH), thyroid hormones, and adrenal androgens in MSD. A systematic search of published evidence was performed using Medline (1969 to September 2011). Oxford Centre for Evidence-Based Medicine-Levels of Evidence (March 2009) was applied when possible. The most important evidence regarding the role played by PRL, GH, thyroid, and adrenal hormone was reviewed and discussed. Only severe hyperprolactinemia (>35 ng/mL or 735 mU/L), often related to a pituitary tumor, has a negative impact on sexual function, impairing sexual desire, testosterone production, and, through the latter, erectile function due to a dual effect: mass effect and PRL-induced suppression on gonadotropin secretion. The latter is PRL-level dependent. Emerging evidence indicates that hyperthyroidism is associated with an increased risk of premature ejaculation and might also be associated with erectile dysfunction (ED), whereas hypothyroidism mainly affects sexual desire and impairs the ejaculatory reflex. However, the real incidence of thyroid dysfunction in subjects with sexual problems needs to be evaluated. Prevalence of ED and decreased libido increase in acromegalic patients; however, it is still a matter of debate whether GH excess (acromegaly) may create effects due to a direct overproduction of GH/insulin-like growth factor 1 or because of the pituitary mass effects on gonadotropic cells, resulting in hypogonadism. Finally, although dehydroepiandrosterone (DHEA) and its sulfate have been implicated in a broad range of biological derangements, controlled trials have shown that DHEA administration is not useful for improving male sexual function. While the association between hyperprolactinemia and hypoactive sexual desire is well defined, more studies are needed to completely understand the role of other hormones in

    A systematic search of Medline, EMBASE and CINAHL electronic databases was performed. Original research articles reporting all-cause mortality following surgery in patients with aortic regurgitation and severe left ventricular systolic dysfunction (LVSD) were identified. Nine of the 10 eligible studies were observational, single-center, retrospective analyses. Survival ranged from 86 to 100% at 30 days; 81 to 100% at 1 year and 68 to 84% at 5 years. Three studies described an improvement in mean left ventricular ejection fraction (LVEF) following aortic valve replacement (AVR) of 5-14%; a fourth study reported an increase in mean left ventricular ejection fraction (LVEF) of 9% in patients undergoing isolated AVR but not when AVR was combined with coronary artery bypass graft and/or mitral valve surgery. Three studies demonstrated improvements in functional New York Heart Association (NYHA) class following AVR. Additional studies are needed to clarify the benefits of AVR in patients with more extreme degrees of left ventricular systolic dysfunction (LVSD) and the potential roles of cardiac transplantation and transaortic valve implantation.

    Full Text Available Emperor Shen-Nung was the second of China′s mythical emperors (3500-2600 BCE. Widely considered the father of Chinese medicine, he catalogued over 365 species of medicinal plants which he personally tasted. Through his treatise ′Shen Nung Benchau Jing′, we relive Emperor Shen-Nung′s contribution to urology with reference to his management of erectile dysfunction. Time-related sources in medical and historical literature were reviewed, including the ′Shen Nung Benchau Jing′ (The medicine book of Emperor Shen-Nung, archives and manuscripts at the Wellcome History of Medicine Collection, the Royal Society of Medicine, London, The Hong Kong Museum of Medical Sciences, and The Museum of Medical History, Shanghai, China. Chinese traditional herbal medicine began approximately 5000 years ago. Agricultural clan leader, Emperor Shen-Nung, was said to have a ′crystal-like belly′ to watch the reactions in his own stomach of the herbs he collected. Ginseng was among of Shen Nung′s contributions to herbal medicine. He experienced a warm and sexually pleasurable feeling after chewing the root. He advocated this as a treatment for erectile dysfunction and used it to stimulate sexual appetite. The reputation of ginseng as an aphrodisiac is based on the doctrine of signatures, since the adult root has a phallic shape. Shen-Nung believed that ginseng′s resemblance to the human form is proof of its rejuvenative and aphrodisiac properties. It was believed that the closer the similarity to the human figure, the more potent the root. The use of ginseng for erectile dysfunction by Emperor Shen-Nung was unique for its time. It continues to hold parallels as a modern-day herbal aphrodisiac 5000 years on.

    Pituitary dysfunction is a recognised, but potentially underdiagnosed complication of traumatic brain injury (TBI). Post-traumatic hypopituitarism (PTHP) can have major consequences for patients physically, psychologically, emotionally and socially, leading to reduced quality of life, depression and poor rehabilitation outcome. However, studies on the incidence of PTHP have yielded highly variable findings. The risk factors and pathophysiology of this condition are also not yet fully understood. There is currently no national consensus for the screening and detection of PTHP in patients with TBI, with practice likely varying significantly between centres. In view of this, a guidance development group consisting of expert clinicians involved in the care of patients with TBI, including neurosurgeons, neurologists, neurointensivists and endocrinologists, was convened to formulate national guidance with the aim of facilitating consistency and uniformity in the care of patients with TBI, and ensuring timely detection or exclusion of PTHP where appropriate. This article summarises the current literature on PTHP, and sets out guidance for the screening and management of pituitary dysfunction in adult patients with TBI. It is hoped that future research will lead to more definitive recommendations in the form of guidelines. PMID:28860331

    Full Text Available Erectile dysfunction (ED is prevalent among men and its presence is often an indicator of systemic disease. Risk factors for ED include cardiovascular disease, hypertension, diabetes mellitus (DM, tobacco use, hyperlipidemia, hypogonadism, lower urinary tract symptoms, metabolic syndrome, and depression. Addressing the modifiable risk factors frequently improves a patient’s overall health and increases lifespan. The literature suggests that smoking cessation, treatment of hyperlipidemia, and increasing physical activity will improve erectile function in many patients. How the treatment of DM, depression, and hypogonadism impacts erectile function is less clear. Clinicians need to be aware that certain antihypertensive agents can adversely impact erectile function. The treatment of men with ED needs to address the underlying risk factors to ameliorate the disease process.

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

    The risk for disordered oropharyngeal swallowing (dysphagia) increases with age. Loss of swallowing function can have devastating health implications including dehydration, malnutrition, and pneumonia, as well as reduced quality of life. Age-related changes place older adults at risk for dysphagia for two major reasons: One is that natural, healthy aging takes its toll on head and neck anatomy and physiologic and neural mechanisms underpinning swallowing function. This progression of change contributes to alterations in the swallowing in healthy older adults and is termed presbyphagia, naturally diminishing functional reserve. Second, disease prevalence increases with age and dysphagia is a co-morbidity of many age-related diseases and/or their treatments. Sensory changes, medication, sarcopenia and age-related diseases are discussed herein. Relatively recent findings that health complications are associated with dysphagia are presented. Nutrient requirements, fluid intake and nutritional assessment for older adults are reviewed relative to their relations to dysphagia. Dysphagia screening and the pros and cons of tube feeding as a solution are discussed. Optimal intervention strategies for elders with dysphagia ranging from compensatory interventions to more rigorous exercise approaches are presented. Compelling evidence of improved functional swallowing and eating outcomes resulting from active rehabilitation focusing on increasing strength of head and neck musculature is provided. In summary, while oropharyngeal dysphagia may be life-threatening, so are some of the traditional alternatives, particularly for frail, elderly patients. While the state of the evidence calls for more research, this review indicates the behavioral, dietary and environmental modifications emerging in this past decade are compassionate, promising and in many cases preferred alternatives to the always present option of tube feeding.

    Clinically, reclining posture has been reported to reduce risk of aspiration. However, during involuntary swallow in reclining posture, changes in orofacial and pharyngeal movement before and during pharyngeal swallow should be considered. Further, the mechanisms underlying the effect of body posture on involuntary swallow remain unclear. The aim of the present study was to determine the effect of body posture on activity patterns of the suprahyoid muscles and on patterns of bolus transport during a natural involuntary swallow. Thirteen healthy male adults participated in a water infusion test and a chewing test. In the water infusion test, thickened water was delivered into the pharynx at a very slow rate until the first involuntary swallow was evoked. In the chewing test, subjects were asked to eat 10 g of gruel rice. In both tests, the recording was performed at four body postures between upright and supine positions. Results showed that reclining changed the location of the bolus head at the start of swallow and prolonged onset latency of the swallowing initiation. Muscle burst duration and whiteout time measured by videoendoscopy significantly increased with body reclining and prolongation of the falling time. In the chewing test, reclining changed the location of the bolus head at the start of swallow, and the frequency of bolus residue after the first swallow increased. Duration and area of EMG burst and whiteout time significantly increased with body reclining. These data suggest that body reclining may result in prolongation of pharyngeal swallow during involuntary swallow. Copyright © 2015 Elsevier Inc. All rights reserved.

  8. Executive Dysfunction

    Purpose of Review: Executive functions represent a constellation of cognitive abilities that drive goal-oriented behavior and are critical to the ability to adapt to an ever-changing world. This article provides a clinically oriented approach to classifying, localizing, diagnosing, and treating disorders of executive function, which are pervasive in clinical practice. Recent Findings: Executive functions can be split into four distinct components: working memory, inhibition, set shifting, and fluency. These components may be differentially affected in individual patients and act together to guide higher-order cognitive constructs such as planning and organization. Specific bedside and neuropsychological tests can be applied to evaluate components of executive function. While dysexecutive syndromes were first described in patients with frontal lesions, intact executive functioning relies on distributed neural networks that include not only the prefrontal cortex, but also the parietal cortex, basal ganglia, thalamus, and cerebellum. Executive dysfunction arises from injury to any of these regions, their white matter connections, or neurotransmitter systems. Dysexecutive symptoms therefore occur in most neurodegenerative diseases and in many other neurologic, psychiatric, and systemic illnesses. Management approaches are patient specific and should focus on treatment of the underlying cause in parallel with maximizing patient function and safety via occupational therapy and rehabilitation. Summary: Executive dysfunction is extremely common in patients with neurologic disorders. Diagnosis and treatment hinge on familiarity with the clinical components and neuroanatomic correlates of these complex, high-order cognitive processes. PMID:26039846

    This study aims to investigate the effect of unripe plantain (Musa paradisiaca) on markers of hepatic dysfunction in streptozotocin induced diabetic rats. Blood glucose; relative liver weight (RLW); relative kidney weight (RKW); relative heart weight (RHW); relative pancreatic weight (RPW); serum and hepatic serum aspartate transaminase (AST), alanine transaminase (ALT), and alkaline phosphatase (ALP); serum amylase, lipase, total, and conjugated bilirubin; and chemical analysis of the test feed were determined using standard techniques. The diabetic rats had significant alteration (P 0.05) in the RHW of the rats in the three groups, as well as significant decreases (P 0.05) in the amylase levels of the rats fed unripe plantain compared with the nondiabetic rats. The test and standard rat feeds contained considerable amount of proteins, carbohydrates, fats, phenols, and crude fiber. Amelioration of acute pancreatitis by unripe plantain could play a key role in its management of diabetes and related complications.

    Full Text Available Background and Objectives: Myofascial Pain Dysfunction Syndrome (MPDS has been recognized as the most common, nontooth-related chronic orofacial pain condition that confronts dentists. A variety of therapies has been described in literature for its management. The present study is a prospective study carried out to evaluate the efficacy of occlusal splint therapy and compare it with pharmacotherapy (using analgesics and muscle relaxants in the management of Myofascial Pain Dysfunction Syndrome. Materials and Methods: Forty patients in the age range of 17-55 years were included in the study and randomly assigned to one of two equally sized groups, A and B. Group A patients received a combination of muscle relaxants and analgesics while Group B patients received soft occlusal splint therapy. All the patients were evaluated for GPI, VAS, maximum comfortable mouth opening, TMJ clicking and tenderness during rest and movement as well as for the number of tender muscles at the time of diagnosis, after the 1 st week of initiation of therapy and every month for three months of follow-up. Results: There was a progressive decrease in GPI scores, number of tender muscles, TMJ clicking and tenderness with various jaw movements and significant improvement in mouth opening in patients on occlusal splint therapy during the follow-up period as compared to the pharmacotherapy group. Conclusion: Occlusal splint therapy has better long-term results in reducing the symptoms of MPDS. It has better patient compliance, fewer side effects, and is more cost-effective than pharmacotherapy; hence, it can be chosen for the treatment of patients with MPDS.

It affects the entire gastrointestinal tract, predominantly by activating opioid receptors in the enteric nervous system, resulting in a wide range of symptoms, such as reflux, bloating, abdominal cramping, hard, dry stools, and incomplete evacuation. The majority of studies evaluating OIBD focus on constipation experienced in approximately 60% of patients. Nevertheless, other presentations of OIBD seem to be equally frequent. Furthermore, laxative treatment is often insufficient, which in many patients results in decreased quality of life and discontinuation of opioid treatment. Novel mechanism-based pharmacological approaches targeting the gastrointestinal opioid receptors have been marketed recently and even more are in the pipeline. One strategy is prolonged release formulation of the opioid antagonist naloxone (which has limited systemic absorption and oxycodone in a combined tablet. Another approach is peripherally acting, µ-opioid receptor antagonists (PAMORAs that selectively target µ-opioid receptors in the gastrointestinal tract. However, in Europe the only PAMORA approved for OIBD is the subcutaneously administered methylnaltrexone. Alvimopan is an oral PAMORA, but only approved in the US for postoperative ileus in hospitalized patients. Finally, naloxegol is a novel, oral PAMORA expected to be approved soon. In this review, the prevalence and pathophysiology of OIBD is presented. As PAMORAs seem to be a promising approach, their potential

    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.

    Temporomandibular disorders (TMDs) represent a group of painful conditions involving the muscles of mastication and the temporomandibular joint (TMJ) that frequently encountered in general clinical practice. This study is designed to assess the utility of vacuum pressed silicon sheet as a bite raising appliance in the management of TMJ dysfunction syndrome. The patients for this study were selected from those with the chief complaint of TMJ disorder. Out of 200 patients, 104 patients were diagnosed with subluxation and 96 patients were diagnosed with internal derangement of temporomandibular joint. All the reported cases were managed conservatively with physiotherapy and muscle relaxant therapy for one week period and followed with silicon bite raising appliance over both the arches in the subsequent period. All the patients had pain relief within six months duration as graded over verbal analog scale. ANOVA scale was used for comparision of VAS scores. The use of vacuum pressed bite raising appliance in the management of TMJ disorder was found to be satisfactorily effective in alleviation of pain symptom in our study group.

    Full Text Available Background: Dysfunctional uterine bleeding (DUB is one of the most common gynecological disorders encountered in women during the reproductive age. Yoga therapy has shown promising benefits in several gynecological disorders. Methods: Thirty women between the ages of 20 and 40 years with primary DUB were randomly assigned to a yoga (n = 15 and a waitlist control group (n = 15. Participants in the yoga group received a 3-month yoga module and were assessed for hemoglobin values, endometrial thickness (ET, pictorial blood loss assessment chart (PBAC, State-Trait Anxiety Inventory, perceived stress scale, and Pittsburgh Sleep Quality Index (PSQI before and after a 3-month follow-up period. Results: At the end of 3 months of intervention, the yoga group, unlike the control group, reported a significant reduction in the anxiety scores (P < 0.05 and perceived stress (P < 0.05. The PSQI scores indicated a reduction in sleep disturbances (P < 0.001 and the need for sleep medications (P < 0.01 and higher global scores (P < 0.001. However, there were no changes in PBAC and ET in both the groups. Conclusion: The results indicate that yoga therapy positively impacts the outcome of DUB by reducing the perceived stress and state anxiety and improving the quality of sleep. This warrants larger clinical trials to validate the findings of this pilot study.

    Some patients with multiple system atrophy (MSA) require surgical interventions such as tracheostomy and aspiration prevention. Few studies have investigated the postoperative clinical course of MSA patients. The aim of this study was to determine a management strategy for dysphagia and respiratory disorder in MSA. From 2001 to 2014, 18 MSA patients (13 males and 5 females, 52-76 years) underwent tracheostomy (TR, n = 11) or laryngeal closure (LC, n = 12). Five patients underwent LC following TR. Vocal fold impairment, the degree of dysphagia and pre/post-operative oral ingestion, and postoperative survival time were evaluated retrospectively. Swallowing function was assessed using the penetration aspiration scale (PAS). TR was performed due to respiratory disorder in seven patients and due to dysphagia in four patients. PAS scores ranged 1-8 in TR patients and 7-8 in LC patients. Seven of 11 patients who underwent TR displayed worsened PAS scores, and no patients displayed improved PAS scores following TR. All patients who underwent LC regained complete or partial oral intake after surgery. There were no significant differences in postoperative survival time between the two groups. Considering the impacts of TR and LC on survival time, postoperative feeding and swallowing, LC is a good option for treating MSA patients with dysphagia. © 2015 EAN.

    Treatment with amiodarone is associated with changes in thyroid function tests, but also with thyroid dysfunction (amiodarone-induced hypothyroidism, AIH, and amiodarone-induced thyrotoxicosis, AIT). Both AIH and AIT may develop in apparently normal thyroid glands or in the presence of underlying thyroid abnormalities. AIH does not require amiodarone withdrawal, and is treated with levothyroxine replacement if overt, whereas subclinical forms may be followed without treatment. Two main types of AIT are recognized: type 1 AIT (AIT 1), a form of iodine-induced hyperthyroidism occurring in nodular goitres or latent Graves disease, and type 2 AIT (AIT 2), resulting from destructive thyroiditis in a normal thyroid gland. Mixed/indefinite forms exist due to both pathogenic mechanisms. AIT 1 is best treated with thionamides that may be combined for a few weeks with sodium perchlorate to make the thyroid gland more sensitive to thionamides. AIT 2 is treated with oral glucocorticoids. Once euthyroidism has been restored, AIT 2 patients are followed up without treatment, whereas AIT 1 patients should be treated with thyroidectomy or radioiodine. Mixed/indefinite forms of AIT are treated with thionamides. Oral glucocorticoids can be added from the beginning if a precise diagnosis is uncertain, or after a few weeks if response to thionamides alone is poor. The decision to continue or to stop amiodarone in AIT should be individualized in relation to cardiovascular risk stratification and taken jointly by specialist cardiologists and endocrinologists. In the presence of rapidly deteriorating cardiac conditions, emergency thyroidectomy may be required for all forms of AIT.

    Full Text Available Polycystic ovary syndrome (PCOS is a common endocrine disorder in women of reproductive age. Its cause is unknown and it remains the most enigmatic of reproductive disorders. The extant written documents of Traditional Persian Medicine (TPM – with holistic approaches towards human health – contain remedies used for centuries. Before further experimental research on any of these treatments, it is appropriate to study current related scientific evidence on their possible pharmacological actions. This work aims to study PCOS and its treatments in TPM. To collect data from medieval medicinal texts, six of the most famous manuscripts of Persian medicine were studied. Medicinal treatments for a problem similar to PCOS were searched for in these books. The plants were listed and their authentications were confirmed in accordance with botanical books. PubMed and ScienceDirect databases were searched for related mechanisms of action or pharmacological activities of the medicinal plants reported. From numerous articles, the current work tried to cite the latest publications with regard to each reported plant and PCOS-related mechanisms of action. We studied herbal treatments recommended by ancient Persians to treat a condition called Habs-e-tams, which had the same symptoms of PCOS. It could be concluded that ancient physicians not only wanted to treat the irregular menstrual cycle—which is the most obvious symptom of PCOS—but also their treatment options were aimed at ameliorating the related underlying metabolic dysfunctions. The recommended herbs, which have the most scientific proof for their related actions, can be studied further in experimental analyses.

  19. Chronic stress, cortisol dysfunction, and pain: a psychoneuroendocrine rationale for stress management in pain rehabilitation.

    2014-12-01

    Pain is a primary symptom driving patients to seek physical therapy, and its attenuation commonly defines a successful outcome. A large body of evidence is dedicated to elucidating the relationship between chronic stress and pain; however, stress is rarely addressed in pain rehabilitation. A physiologic stress response may be evoked by fear or perceived threat to safety, status, or well-being and elicits the secretion of sympathetic catecholamines (epinephrine and norepinepherine) and neuroendocrine hormones (cortisol) to promote survival and motivate success. Cortisol is a potent anti-inflammatory that functions to mobilize glucose reserves for energy and modulate inflammation. Cortisol also may facilitate the consolidation of fear-based memories for future survival and avoidance of danger. Although short-term stress may be adaptive, maladaptive responses (eg, magnification, rumination, helplessness) to pain or non-pain-related stressors may intensify cortisol secretion and condition a sensitized physiologic stress response that is readily recruited. Ultimately, a prolonged or exaggerated stress response may perpetuate cortisol dysfunction, widespread inflammation, and pain. Stress may be unavoidable in life, and challenges are inherent to success; however, humans have the capability to modify what they perceive as stressful and how they respond to it. Exaggerated psychological responses (eg, catastrophizing) following maladaptive cognitive appraisals of potential stressors as threatening may exacerbate cortisol secretion and facilitate the consolidation of fear-based memories of pain or non-pain-related stressors; however, coping, cognitive reappraisal, or confrontation of stressors may minimize cortisol secretion and prevent chronic, recurrent pain. Given the parallel mechanisms underlying the physiologic effects of a maladaptive response to pain and non-pain-related stressors, physical therapists should consider screening for non-pain-related stress to

    The role of hyoidthyroidpexia (HTP) surgery in the management of patients with obstructive sleep apnea (OSA) is well described with good reported outcomes. The effect of HTP on other laryngeal functions is not well discussed. This study was designed to evaluate voice and swallowing outcomes after HTP. This study was applied on a selected group of OSA patients. HTP (as a sole procedure) was performed in 17 patients and 14 patients had simultaneous palatal procedures (e.g., anterior palatoplasty). Pre- and postoperative assessment of voice and swallowing were done. Comparison between pre- and postoperative results of voice and swallowing measures revealed a nonsignificant difference. HTP (as a sole technique or as part of a multilevel intervention) could help with airway collapse and might be considered a safe, simple, and effective technique in the management of selected patients experiencing OSA. In addition, it seems to have no hazardous effect on either the voice or swallowing function of patients. © 2018 S. Karger AG, Basel.

    Until now, no questionnaire has been developed to study specific expectations concerning sexual dysfunction management and the availability of information on sexuality in the female population affected by multiple sclerosis (MS). Understanding and meeting the patient's expectations is an issue of considerable importance in the evaluation of medical care. We present the development and validation of a specific questionnaire designed for women with MS in order to assess their expectations in terms of sexual dysfunction management: the SEA-MS-F (Sexual Dysfunction Management and Expectations Assessment in Multiple Sclerosis-Female). This questionnaire was created and validated by an expert panel, using the Delphi method. The psychometric evaluation was obtained with a sample of 40 female MS patients. Cronbach's alpha index and principal component analysis were used to measure the questionnaire's internal consistency. A consensus on the questionnaire was reached with the Delphi method. The SEA-MS-F is fully compliant with the criteria for psychometric validation among female MS patients, and its internal consistency is excellent (Cronbach's alpha 0.948). The SEA-MS-F appears to be a useful tool that could be used either in routine medical situations or in prospective studies of MS in order to ascertain women's expectations concerning the management of their sexual dysfunction. © 2014 International Society for Sexual Medicine.

    Full Text Available Huntington’s disease (HD has been described as a genetic condition caused by a mutation in the CAG (cytosine-adenine-guanine nucleotide sequence. Depending on the stage of the disease, people may have difficulties in speech, language and swallowing. The purpose of this paper is to describe these difficulties in detail, as well as to provide an account on speech and language therapy approach to this condition. Regarding speech, it is worth noticing that characteristics typical of hyperkinetic dysarthria can be found due to underlying choreic movements. The speech of people with HD tends to show shorter sentences, with much simpler syntactic structures, and difficulties in tasks that require complex cognitive processing. Moreover, swallowing may present dysphagia that progresses as the disease develops. A timely, comprehensive and effective speech-language intervention is essential to improve the quality of life of people and contribute to their communicative welfare.

    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.

    Cervical auscultation (CA) may be used to complement feeding/swallowing evaluations when assessing for aspiration. There are no published pediatric studies that compare the properties of sounds between aspirating and nonaspirating swallows. To establish acoustic and perceptual profiles of aspirating and nonaspirating swallow sounds and determine if a difference exists between these 2 swallowing types. Aspiration sound clips were obtained from recordings using CA simultaneously undertaken with videofluoroscopic swallow study. Aspiration was determined using the Penetration-Aspiration Scale. The presence of perceptual swallow/breath parameters was rated by 2 speech pathologists who were blinded to the type of swallow. Acoustic data between groups were compared using Mann Whitney U-tests, while perceptual differences were determined by a test of 2 proportions. Combinations of perceptual parameters of 50 swallows (27 aspiration, 23 no aspiration) from 47 children (57% male) were statistically analyzed using area under a receiver operating characteristic (aROC), sensitivity, specificity, and positive and negative predictive values to determine predictors of aspirating swallows. The combination of post-swallow presence of wet breathing and wheeze and absence of GRS and normal breathing was the best predictor of aspiration (aROC = 0.82, 95% CI, 0.70-0.94). There were no significant differences between these 2 swallow types for peak frequency, duration, and peak amplitude. Our pilot study has shown that certain characteristics of swallow obtained using CA may be useful in the prediction of aspiration. However, further research comparing the acoustic swallowing sound profiles of normal children to children with dysphagia (who are aspirating) on a larger scale is required. © The Author(s) 2016.

    The aim of this study was to investigate the prevalence of kinesiographic coincidence between the most cranial position during deglutition of mandible and habitual occlusal position and to evaluate the distribution of clinical diagnosis according to the kinesiographic pattern of deglutition. 201 random patients in waiting list for dental treatment and classified as orthodontic patients, prosthetic patients, TMD patients and control patients, were evaluated. Kinesiographic records were acquired using K7I and positioning a magnetic sensor frame integral with the head and with the sensory field balanced on an artificial magnet adhering to the mucosa covering the roots of the lower mandibular incisors. The kinesiographic occlusal position was compared to the kinesiographic most cranial position of the mandible during swallowing. 99 patients displayed a discrepancy between the most cranial position during swallowing and the occlusal position. 102 patients did not show any discrepancy. In this group the kinesiographic most cranial position during swallowing coincided with the occlusal position. The finding suggests that computerised kinesiography could be useful to study deglutition, detecting in a reliable way the movement pattern. Atypical deglutition seems to be less atypical than previously though in dental patient population and, despite these data confirm its correlation with malocclusion, we noted an inverse correlation with necessity of prosthetic treatment and no higher prevalence in TMD patients.

    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 doses 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 65 >50%, and GSL V 50 >50%. Reduced laryngeal elevation and epiglottic inversion were correlated with mean PC and GSL doses (p 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

    Thirty-four patients with an identified muscular disease were referred to our department for assessment and treatment of swallowing difficulties. Their ages ranged from 16 to 91 years (mean 59). The diagnoses were oculopharyngeal dystrophy in 17 patients, Steinert myotonic dystrophy in 6, mitochondrial myopathies in 4, polymyositis in 3, and other types in 4 patients. The main consequences of the dysphagia were weight loss (12 patients), pulmonary infections (15 patients), modified food consistency (18 patients) and non-oral feeding (3 patients). Several techniques were used to assess the different stages of deglutition: physical examination during swallowing, videofluoroscopy, pharyngoesophageal manometry, videofibroscopy of the pharynx during swallowing. Major pathological features found in the pharynx were decreased pharynx peristaltis and impaired UES relaxation. Cricopharyngeal myotomy was performed in 11 myopathic patients (median follow-up 24.9 months), while it was unnecessary, refused or contraindicated in the other patients. The procedure was successful in 8 patients whose dysphagia was dramatically improved, and failed in 3 patients. Pharyngeal perstaltis was severely impaired only in the 3 failures and was partly preserved in the improved cases. We conclude that pharyngeal function is the major prognostic factor. Cricopharyngeal myotomy is an effective treatment in those cases where cricopharyngeal dysfunction is a predominant problem or where pharyngeal peristaltis is partly impaired, since the procedure removes one obstacle. It is contraindicated when pharynx propulsion is severely impaired.

    Spasmodic dysphonia is defined as a focal laryngeal disorder characterized by dystonic spasms of the vocal cord during speech. We described a case of a 22-year-old male patient who presented complaining of idiopathic difficulty swallowing that suddenly developed 6 months ago. The patient also reported pharyngolaryngeal pain, throat discomfort, dyspnea, and voice change. Because laryngoscopy found no specific problems, an electrodiagnostic study and videofluoroscopic swallowing study (VFSS) were performed to find the cause of dysphagia. The VFSS revealed continuous twitch-like involuntary movement of the laryngeal muscle around the vocal folds. Then, he was diagnosed with spasmodic dysphonia by VFSS, auditory-perceptual voice analysis, and physical examination. So, we report the first case of spasmodic dysphonia accompanied with difficulty swallowing that was confirmed by VFSS. PMID:25932430

    Evidence-based guidelines for the management of neurological disease and lower urinary tract dysfunction have been produced by the International Consultations on Incontinence (ICI). These are comprehensive guidelines, and were developed to have world-wide relevance. To update clinical management of neurogenic bladder dysfunction from the recommendations of the fourth ICI, 2009. A series of evidence reviews and updates were performed by members of the working group. The resulting guidelines were presented at the 2012 meeting of the European Association of Urology for consultation, and consequently amended to deliver evidence-based conclusions and recommendations in 2013. The current review is a synthesis of the conclusions and recommendations, including the algorithms for initial and specialized management of neurogenic lower urinary tract dysfunction. The pathophysiology is categorized according to the nature of onset of neurological disease and the part(s) of the nervous system affected. Assessment requires clinical evaluation, general investigations, and specialized testing. Treatment primarily focuses on ensuring safety of the patient and optimizing quality of life. Symptom management covers conservative and interventional measures to aid urine storage and bladder emptying, along with containment of incontinence. A multidisciplinary approach to management is essential. The review offers a pragmatic review of management in the context of complex pathophysiology and varied evidence base. Neurourol.

    Sacroiliac joint pain and dysfunction affect 15-25% of patients reporting low back pain, including reports of spontaneous, idiopathic, traumatic, and non-traumatic onsets. The poor reliability and validity associated with diagnostic clinical and imaging techniques leads to challenges in diagnosing and managing sacroiliac joint dysfunction. A 35-year-old nulliparous female with a 14-year history of right sacroiliac joint dysfunction was managed using a multimodal and multidisciplinary approach when symptoms failed to resolve after 2 months of physical therapy. The plan of care included four prolotherapy injections, sacroiliac joint manipulation into nutation, pelvic girdle belting, and specific stabilization exercises. The patient completed 20 physical therapy sessions over a 12-month period. At 6 months, the patient's Oswestry Disability Questionnaire score was reduced from 34% to 14%. At 1-year follow-up, her score was 0%. The patient's rating of pain on a numeric rating scale decreased to an average of 4/10 at 6 months and 0/10 at 1-year follow-up. A multidisciplinary and multimodal approach for the management of chronic sacroiliac joint dysfunction appeared successful in a single-case design at 1-year follow-up.

    Videofluoroscopy is commonly used for evaluating oropharyngeal swallowing but requires radiopaque contrast (typically barium). Prior studies suggest that some aspects of swallowing, including timing measures of oral and pharyngeal bolus transit, vary depending on barium concentration. The aim of our study was to identify timing differences in healthy swallowing between “thin” (40 % w/v concentration) and “ultrathin” (22 % w/v concentration) barium solutions.

    To assess the utility of maintaining and analyzing a quality-management database while investigating a subjectively perceived increase in the incidence of tunneled catheter and port dysfunction in a cohort of oncology outpatients. All 152 patients undergoing lytic therapy (2-4 mg alteplase) of a malfunctioning indwelling central venous catheter (CVC) from January through June 2004 at a single cancer center in the United States were included in a quality-management database. Patients were categorized by time to device failure and the initial method of catheter placement (surgery vs interventional radiology). Data were analyzed after 3 months, and areas of possible improvement were identified and acted upon. Three months of follow-up data were then collected and similarly analyzed. In a 6-month period, 152 patients treated for catheter malfunction received a total of 276 doses of lytic therapy. A 3-month interim analysis revealed a disproportionately high rate (34%) of early catheter malfunction (ECM; <30 days from placement). Postplacement radiographs demonstrated suboptimal catheter positioning in 67% of these patients, all of whom had surgical catheter placement. There was a 50% absolute decrease in the number of patients presenting with catheter malfunction in the period from April through June (P < .001). Evaluation of postplacement radiographs in these patients demonstrated a 50% decrease in the incidence of suboptimal positioning (P < .05). Suboptimal positioning was likely responsible for some, but not all, cases of ECM. Maintenance of a quality-management database is a relatively simple intervention that can have a clear and important impact on the quality and cost of patient care.

The aim of this prospective randomized trial was to evaluate the impact of prophylactic swallowing exercises on swallowing-related outcomes in HNC patients treated with curative...... of the dysphagia outcomes during and after treatment. Adherence to exercises was poor and dropouts due to especially fatigue were very frequent in both groups. Systematic swallowing exercises had no impact on swallowing outcomes within the first year after RT. Despite repeated supervised sessions, adherence...

  15. Variability of the pharyngeal phase of swallow in the cat.

    Daniel G Spearman

    Full Text Available The pharyngeal phase of swallow has been thought to be a stereotypical motor behavior.This is a prospective, preclinical, hypothesis driven, one group by three-task design.We sought to compare the effects of pharyngeal swabbing, water only, and water plus punctate mechanical stimulation on the spatiotemporal features of the pharyngeal phase of swallow in the cat. Swallow was elicited under these three conditions in six anaesthetized cats. Electromyographic activity was recorded from seven muscles used to evaluate swallow: mylohyoid, geniohyoid, thyrohyoid, thyroarytenoid, thyropharyngeus, cricopharyngeus, and parasternal.Pharyngeal swabbing in comparison to the other stimulus conditions, results in decreases in post-swallow cricopharyngeus activity (upper esophageal sphincter; a significant increase in parasternal (schluckatmung; swallow breath activity; and increases in thyrohyoid (laryngeal elevator, thyroarytenoid (laryngeal adductor and parasternal muscles burst duration. Pearson correlations were found of moderate strength between 19% of burst duration comparisons and weak to moderate relationships between 29% of burst amplitude comparisons. However, there were no positive significant relationships between phase durations and electromyogram amplitudes between any of the muscles studied during swallow.The results support the concept that a stereotypical behavior, such as pharyngeal swallowing in animal models, can be modified by sensory feedback from pharyngeal mucosal mechanoreceptors. Furthermore, differences in swallow phase durations and amplitudes provide evidence that separate regulatory mechanisms exist which regulate spatial and temporal aspects of the behavior.

    Swallowing impairment is a common complication in various geriatric and neurodegenerative diseases. Swallowing kinematic analysis is essential to quantitatively evaluate the swallowing motion of the oropharyngeal structures. This study aims to develop a novel swallowing kinematic analysis software, called spatio-temporal analyzer for motion and physiologic study (STAMPS), and verify its validity and reliability. STAMPS was developed in MATLAB, which is one of the most popular platforms for biomedical analysis. This software was constructed to acquire, process, and analyze the data of swallowing motion. The target of swallowing structures includes bony structures (hyoid bone, mandible, maxilla, and cervical vertebral bodies), cartilages (epiglottis and arytenoid), soft tissues (larynx and upper esophageal sphincter), and food bolus. Numerous functions are available for the spatiotemporal parameters of the swallowing structures. Testing for validity and reliability was performed in 10 dysphagia patients with diverse etiologies and using the instrumental swallowing model which was designed to mimic the motion of the hyoid bone and the epiglottis. The intra- and inter-rater reliability tests showed excellent agreement for displacement and moderate to excellent agreement for velocity. The Pearson correlation coefficients between the measured and instrumental reference values were nearly 1.00 (P software is expected to be useful for researchers who are interested in the swallowing motion analysis.

    Purpose: Very little objective data has been reported on mastication and swallowing in xerostomic patients, which would substantiate presumed causal relationships between xerostomia and patient complaints. The purpose was to elucidate which components of mastication and swallowing were abnormal, and most directly related to xerostomia, and which appeared unaffected. Methods and Materials: A retrospective analysis of timing events in mastication and swallowing was done using videofluoroscopic data for 15 cancer patients with xerostomia, and 20 normal controls. Scintigraphy was also used to determine oropharyngeal residue after a water swallow. Cancer treatment modalities included radiation therapy or chemoradiation therapy. Results: For barium liquid and paste substances, timing measures were equivalent for controls and patients. Xerostomic patients took 46% longer to masticate a shortbread cookie, and timing for the initiation of swallowing was shorter, but duration of swallowing appeared unaffected. Oral and pharyngeal residues following the swallow were greater in the patient group. Conclusions: Xerostomia primarily affected mastication and oral manipulation of a dry, absorbent food material. Increased oral and pharyngeal residues after a water swallow are ambiguously related to xerostomia. The initiation and duration of the pharyngeal swallow was not abnormal

The aim of the present study was to explore individuals’ preferences regarding TAI devices and furthermore investigate willingness to pay (WTP for attributes in devices in the UK. Methods: A discrete choice experiment survey was conducted to evaluate the patients’ perceived value of TAI devices. Attributes were selected based upon a literature review and input from clinicians. Interviews were conducted with three clinicians and the survey was developed and finalized with the input from both patients and professionals. The final attributes were “risk of urinary tract infections” (UTIs, “risk of fecal incontinence” (FI, “frequency of use”, “time spent on toilet”, “ease of use”, “level of control/independence”, and “cost”. Participants were recruited by a patient panel of TAI device users in the UK. Data were analyzed using the conditional logit model whereby the coefficients obtained from the model provided an estimate of the (log odds ratios (ORs of preference for attributes. WTP was also estimated for each attribute. Results: A total of 129 participants were included in the final analyses. Sixty two percent of the participants had suffered from three UTIs in the preceding year and 58% of patients reported currently experiencing FI using their current device. All attributes were significant predictors of choice. The most important attributes for participants were the “risk of FI”, “frequency of use”, and “risk of UTIs

    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

    Sacroiliac joint (SIJ) dysfunction is a prevalent cause of chronic, unremitting lower back pain. To concurrently compare outcomes after surgical and nonsurgical treatment for chronic SIJ dysfunction. A total of 148 subjects with SIJ dysfunction were randomly assigned to minimally invasive SIJ fusion with triangular titanium implants (n = 102) or nonsurgical management (n = 46). Pain, disability, and quality-of-life scores were collected at baseline and at 1, 3, 6, and 12 months. Success rates were compared using Bayesian methods. Crossover from nonsurgical to surgical care was allowed after the 6-month study visit was complete. Six-month success rates were higher in the surgical group (81.4% vs 26.1%; posterior probability of superiority > 0.9999). Clinically important (≥ 15 point) Oswestry Disability Index improvement at 6 months occurred in 73.3% of the SIJ fusion group vs 13.6% of the nonsurgical management group (P dysfunction caused by degenerative sacroiliitis or SIJ disruptions. Pain, disability, and quality of life also improved after crossover from nonsurgical to surgical treatment.

    Disuse atrophy of swallowing-related organs due to an excessive decrease in swallowing frequency is suspected to occur in patients with poor oral intake, especially elderly people. However, swallowing frequency in daily life has not previously been examined in the elderly. This study examined swallowing frequency in elderly people and compared these findings to those in a younger population and differences in the degree of activity in daily life. (i) We compared swallowing frequency in 20 elderly people (82·0 ± 8·3 year) and 15 healthy young people (26·5 ± 3·5 year). (ii) 20 elderly people were divided into two groups according to the degree of activity in daily life: a semi-bedridden group and bedridden group; the swallowing frequency was compared between these groups. (i) The swallowing frequency in the elderly people was 2-19 times per hour and the mean was 9·4 ± 4·9, and that in the healthy young people was 16-76 times per hour and the mean was 40·7 ± 19·5. Swallowing frequency in elderly people was significantly lower than that in young healthy people (P bedridden group was 2-11 times per hour and the mean was 6·8 ± 3·3, and that in semi-bedridden group was 3-19 times per hour and the mean was 11·9 ± 5·1. Swallowing frequency in bedridden group was significantly lower than that in semi-bedridden group (P elderly people tend to swallow less frequently than young people. In addition, swallowing frequency was lower in elderly subjects with a low degree of activity in daily life. © 2013 John Wiley & Sons Ltd.

    Purpose: To study survival in two groups of dysphagic patients - one group unable to elicit the pharyngeal stage of swallow (APS) and another group with pharyngeal swallow (WPS) - and to compare recommendations regarding nutrition and therapeutic strategies based on the therapeutic swallowing study. Material and Methods: In this retrospective study, the records of dysphagic patients who have undergone a therapeutic videoradiographic swallowing study (TVSS) were reviewed. Forty patients without pharyngeal swallow were matched for age and gender with 40 patients with pharyngeal swallow; altogether 80 patients were included in the study. Survival was registered at 3, 12, and 72 months after the TVSS. Results: In this study, the APS group had a significantly shorter survival time compared to the WPS group when followed-up at 12 months. In the APS group, most patients (37.5% (15/40)) died within the 3 months after TVSS. At 72 months, 62.5% (25/40) of the patients in the APS group had died. In the WPS group, 5% (2/40) had died within 3 months and 47.4% (19/40) after 12 months. At 72 months, 52.5% (21/40) of the patients in the WPS group had died. Regarding nutritional and therapeutic recommendations based on TVSS, 34/40 in the APS group were recommended no oral intake. Eighteen naso-gastric tubes were placed directly after TVSS. The therapeutic strategies recommended were head-positioning, thermal tactile stimulation, and tongue exercises (in 8 patients). In the WPS group, all patients were recommended oral intake. Diet modification was recommended in 29 patients. The therapeutic strategies recommended were head-positioning, thermal tactile stimulation, tongue exercises, supraglottic swallow, and effortful swallow (in 24 patients). Conclusion: Patients unable to elicit the pharyngeal stage of swallow had a shorter survival time than patients with pharyngeal swallow, probably due to a more severe underlying disease. Tube feeding was more frequent in the APS group. Fewer

    Oropharyngeal dysphagia is a highly prevalent comorbidity in neurological patients and presents a serious health threat, which may lead to outcomes of aspiration pneumonia, ranging from hospitalization to death. This assessment proposes a non-invasive, acoustic-based method to differentiate between individuals with and without signals of penetration and aspiration. This systematic review evaluated the diagnostic validity of different methods for assessment of swallowing sounds, when compared to Videofluroscopic of Swallowing Study (VFSS) to detect oropharyngeal dysphagia. Articles in which the primary objective was to evaluate the accuracy of swallowing sounds were searched in five electronic databases with no language or time limitations. Accuracy measurements described in the studies were transformed to construct receiver operating characteristic curves and forest plots with the aid of Review Manager v. 5.2 (The Nordic Cochrane Centre, Copenhagen, Denmark). The methodology of the selected studies was evaluated using the Quality Assessment Tool for Diagnostic Accuracy Studies-2. The final electronic search revealed 554 records, however only 3 studies met the inclusion criteria. The accuracy values (area under the curve) were 0.94 for microphone, 0.80 for Doppler, and 0.60 for stethoscope. Based on limited evidence and low methodological quality because few studies were included, with a small sample size, from all index testes found for this systematic review, Doppler showed excellent diagnostic accuracy for the discrimination of swallowing sounds, whereas microphone-reported good accuracy discrimination of swallowing sounds of dysphagic patients and stethoscope showed best screening test.

    2014-10-01

    The successful treatment of women with vestibulodynia and its associated chronic pelvic floor dysfunctions requires interventions that address a broad field of possible pain contributors. Pelvic floor muscle hypertonicity was implicated in the mid-1990s as a trigger of major chronic vulvar pain. Painful bladder syndrome, irritable bowel syndrome, fibromyalgia, and temporomandibular jaw disorder are known common comorbidities that can cause a host of associated muscular, visceral, bony, and fascial dysfunctions. It appears that normalizing all of those disorders plays a pivotal role in reducing complaints of chronic vulvar pain and sexual dysfunction. Though the studies have yet to prove a specific protocol, physical therapists trained in pelvic dysfunction are reporting success with restoring tissue normalcy and reducing vulvar and sexual pain. A review of pelvic anatomy and common findings are presented along with suggested physical therapy management. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available OBJECTIVE: To characterize the problems of feeding and swallowing in individuals with moderate and severe Alzheimer´s disease (AD and to correlate these with functional aspects. METHOD: Fifty patients with AD and their caregivers participated in this study. The instruments used were: Clinical Dementia Rating (CDR, Mini-Mental State Examination, Index of Activities of Daily Living, Assessment of Feeding and Swallowing Difficulties in Dementia, Functional Outcome Questionnaire for Aphasia, and Swallowing Rating Scale. RESULTS: Problems with passivity, distraction and refusal to eat were encountered in the CDR2 group. Distraction, passivity and inappropriate feeding velocity were predominant in the CDR3 group. The problems were correlated with communication, swallowing severity of AD individuals and caregiver schooling. CONCLUSION: Given the inexorable functional alterations during the course of the disease, it is vital to observe these in patients with a compromised feeding and swallowing mechanism. The present study supplies the instruments to orient caregivers and professionals.

    BACKGROUND: Sacroiliac joint (SIJ) dysfunction is a prevalent cause of chronic, unremitting lower back pain. OBJECTIVE: To concurrently compare outcomes after surgical and nonsurgical treatment for chronic SIJ dysfunction. METHODS: A total of 148 subjects with SIJ dysfunction were randomly assigned to minimally invasive SIJ fusion with triangular titanium implants (n = 102) or nonsurgical management (n = 46). Pain, disability, and quality-of-life scores were collected at baseline and at 1, 3, 6, and 12 months. Success rates were compared using Bayesian methods. Crossover from nonsurgical to surgical care was allowed after the 6-month study visit was complete. RESULTS: Six-month success rates were higher in the surgical group (81.4% vs 26.1%; posterior probability of superiority > 0.9999). Clinically important (≥ 15 point) Oswestry Disability Index improvement at 6 months occurred in 73.3% of the SIJ fusion group vs 13.6% of the nonsurgical management group (P Sacroiliac Fusion Treatment MCS, mental component summary NSM, nonsurgical management ODI, Oswestry Disability Index PCS, physical component summary RFA, radiofrequency ablation SF-36, Short Form-36 SIJ, sacroiliac joint TTO, time trade-off VAS, visual analog scale PMID:26291338

    Swallowing pressure generation is important to ensure safe transport of an ingested bolus without aspiration or leaving residue in the pharynx. To clarify the mechanism, we measured swallowing pressure at the oropharynx (OP), upper esophageal sphincter (UES), and cervical esophagus (CE) using a specially designed manometric catheter in anesthetized rats. A swallow, evoked by punctate mechanical stimulation to the larynx, was identified by recording activation of the suprahyoid and thyrohyoid muscles using electromyography (EMG). Areas under the curve of the swallowing pressure at the OP, UES, and CE from two trials indicated high intrasubject reproducibility. Effects of transecting the hypoglossal nerve (12N) and recurrent laryngeal nerve (RLN) on swallowing were investigated. Following bilateral hypoglossal nerve transection (Bi-12Nx), OP pressure was significantly decreased, and time intervals between peaks of thyrohyoid EMG bursts and OP pressure were significantly shorter. Decreased OP pressure and shortened times between peaks of thyrohyoid EMG bursts and OP pressure following Bi-12Nx were significantly increased and longer, respectively, after covering the hard and soft palates with acrylic material. UES pressure was significantly decreased after bilateral RLN transection compared with that before transection. These results suggest that the 12N and RLN play crucial roles in OP and UES pressure during swallowing, respectively. We speculate that covering the palates with a palatal augmentation prosthesis may reverse the reduced swallowing pressure in patients with 12N or tongue damage by the changes of the sensory information and of the contact between the tongue and a palates. NEW & NOTEWORTHY Hypoglossal nerve transection reduced swallowing pressure at the oropharynx. Covering the hard and soft palates with acrylic material may reverse the reduced swallowing function caused by hypoglossal nerve damage. Recurrent laryngeal nerve transection reduced upper

    To provide an overview of our current understanding of exercise-induced reproductive dysfunction and an approach to its evaluation and management. A MEDLINE search was performed to review all articles with title words related to menstrual dysfunction, amenorrhea, oligomenorrhea, exercise, and athletic activities from 1966 to 1998. The pathophysiology, proposed mechanisms, clinical manifestations, evaluation, and management of exercise-associated reproductive dysfunction were compiled. Exercise-induced menstrual irregularity appears to be multifactorial in origin and remains a diagnosis of exclusion. The underlying mechanisms are mainly speculative. Clinical manifestations range from luteal phase deficiency to anovulation, amenorrhea, and even delayed menarche. Evaluation should include a thorough history and a complete physical plus pelvic examination. Most cases are reversible with dietary and exercise modifications. Hormonal replacement in cases of a prolonged hypoestrogenic state with evidence of increased bone loss is recommended, although the long-term consequences of prolonged hormonal deficiency are ill-defined.

  15. Motor imagery and swallowing: a systematic literature review

    Directory of Open Access Journals (Sweden)

    Ada Salvetti Cavalcanti Caldas

    Full Text Available ABSTRACT Objetive: to identify, in the literature, studies that address the use of motor imagery of swallowing. Methods: a systematic review in SCOPUS databases, Science Direct and Medline, with descriptors and free terms "Motor Imagery"; "Swallow"; "Feeding"; "Stomatognathic System"; "mastication ", "Chew "; "Deglutition "; "Deglutition Disorders "; and "Mental Practice". Original articles using the motor imagery of swallowing were included, while reviews were excluded. For data analysis, at the first and second steps, the reading of titles and abstracts of the studies was carried out. In the third step, all studies that were not excluded were read in full. Results: four manuscripts were selected. The use of motor imagery in the rehabilitation of swallowing shows to be a recent proposal (2014-2015. The sample was reduced and comprised mainly healthy individuals. The EMG of the supra-hyoid muscles was used in two manuscripts. The most used neuroimaging technique was the Near-Infrared Spectroscopy, demonstrating the occurrence of hemodynamic changes during motor imagery and motor execution of swallowing. Conclusion: the motor imagery produces brain response in the motor area of the brain, suggesting that mentalization of actions related to swallowing is effective. However, further studies are needed for the application of this approach in the swallowing rehabilitation.

    Videofluoroscopy is commonly used for evaluating oropharyngeal swallowing but requires radiopaque contrast (typically barium). Prior studies suggest that some aspects of swallowing, including timing measures of oral and pharyngeal bolus transit, vary depending on barium concentration. The aim of our study was to identify timing differences in healthy swallowing between "thin" (40 % w/v concentration) and "ultrathin" (22 % w/v concentration) barium solutions. Twenty healthy adults (Ten women; mean age = 31 years) each performed a series of three noncued 5-ml swallows each of ultrathin and thin liquid barium solutions in videofluoroscopy. Timing measures were compared between barium concentrations using a mixed-model ANOVA. The measures of interest were stage transition duration, pharyngeal transit time, and duration of upper esophageal sphincter opening. Significant differences were observed in the timing measures of swallowing with respect to barium concentration. In all cases, longer durations were seen with the higher barium concentration. Barium concentration influences timing parameters in healthy swallowing, even between ultrathin and thin concentrations. Clinicians need to understand and control for the impact of different barium stimuli on swallowing physiology.

    We previously prepared and pharmaceutically evaluated ginger orally disintegrating (OD) tablets, optimized the base formulation, and carried out a clinical trial in healthy adults in their 20 s and 50s to measure their effect on salivary substance P (SP) level and improved swallowing function. In this study, we conducted clinical trials using the ginger OD tablets in older people to clinically evaluate the improvements in swallowing function resulting from the functional components of the tablet. The ginger OD tablets were prepared by mixing the excipients with the same amount of mannitol and sucrose to a concentration of 1% ginger. Eighteen healthy older adult volunteers aged 63 to 90 were included in the swallowing function test. Saliva was collected before and 15 min after administration of the placebo and ginger OD tablets. Swallowing endoscopy was performed by an otolaryngologist before administration and 15 min after administration of the ginger OD tablets. A scoring method was used to evaluate the endoscopic swallowing. Fifteen minutes after taking the ginger OD tablets, the salivary SP amount was significantly higher than prior to ingestion or after taking the placebo (pginger OD tablets. Our findings showed that the ginger OD tablets increased the salivary SP amount and improved swallowing function in older people with appreciably reduced swallowing function.

    Full Text Available Abstract Background Dysphagia is a leading complication in stroke patients causing aspiration pneumonia, malnutrition and increased mortality. Current strategies of swallowing therapy involve on the one hand modification of eating behaviour or swallowing technique and on the other hand facilitation of swallowing with the use of pharyngeal sensory stimulation. Thermal tactile oral stimulation (TTOS is an established method to treat patients with neurogenic dysphagia especially if caused by sensory deficits. Little is known about the possible mechanisms by which this interventional therapy may work. We employed whole-head MEG to study changes in cortical activation during self-paced volitional swallowing in fifteen healthy subjects with and without TTOS. Data were analyzed by means of synthetic aperture magnetometry (SAM and the group analysis of individual SAM data was performed using a permutation test. Results Compared to the normal swallowing task a significantly increased bilateral cortical activation was seen after oropharyngeal stimulation. Analysis of the chronological changes during swallowing suggests facilitation of both the oral and the pharyngeal phase of deglutition. Conclusion In the present study functional cortical changes elicited by oral sensory stimulation could be demonstrated. We suggest that these results reflect short-term cortical plasticity of sensory swallowing areas. These findings facilitate our understanding of the role of cortical reorganization in dysphagia treatment and recovery.

    Many animals use photoperiod cues to synchronize reproduction with environmental conditions and thereby improve their reproductive success. The circadian clock, which creates endogenous behavioral and physiological rhythms typically entrained to photoperiod, is well characterized at the molecular level. Recent work provided evidence for an association between Clock poly-Q length polymorphism and latitude and, within a population, an association with the date of laying and the length of the incubation period. Despite relatively high overall breeding synchrony, the timing of clutch initiation has a large impact on the fitness of swallows in the genus Tachycineta. We compared length polymorphism in the Clock poly-Q region among five populations from five different Tachycineta species that breed across a hemisphere-wide latitudinal gradient (Fig. 1). Clock poly-Q variation was not associated with latitude; however, there was an association between Clock poly-Q allele diversity and the degree of clutch size decline within breeding seasons. We did not find evidence for an association between Clock poly-Q variation and date of clutch initiation in for any of the five Tachycineta species, nor did we found a relationship between incubation duration and Clock genotype. Thus, there is no general association between latitude, breeding phenology, and Clock polymorphism in this clade of closely related birds.Figure 1Photos of Tachycineta swallows that were used in this study: A) T. bicolor from Ithaca, New York, B) T. leucorrhoa from Chascomús, Argentina, C) T. albilinea from Hill Bank, Belize, D) T. meyeni from Puerto Varas, Chile, and E) T. thalassina from Mono Lake, California, Photographers: B: Valentina Ferretti; A, C-E: David Winkler.

    The tongue contributes to a safe swallow. It facilitates bolus control during mastication, maintains a bolus in the oral cavity to prevent premature entry of the bolus into the hypopharynx, and helps generate pressure in the hypopharynx during swallowing. This study examined isometric tongue strength and tongue pressure measured during swallowing in healthy young and older adults. Prospective group design. One hundred twenty-six healthy individuals who were recruited as part of a larger study on swallowing participated in this study. Participants were divided into three age groups: 20 to 40 years, 41 to 60 years, and ≥61 years. A KayPentax Digital Swallowing Workstation with an air-filled bulb array was placed on the tongue of each participant (anterior to posterior). Participants completed three isometric tongue presses and three swallows. Repeated measures analyses of variance revealed a significant main effect of age (P = .01) and gender by tongue bulb location interaction (P = .02) for isometric tongue strength. That is, older adults had lower isometric tongue strength than young adults, and females had a greater difference between anterior and posterior tongue strength than males. Tongue strength during swallowing yielded significantly greater anterior versus posterior tongue pressure. This study comprises one of the largest in terms of number of healthy participants reported to date and confirms previous findings that isometric tongue strength decreases with age. Furthermore, given young and older adults generate similar swallowing pressures, swallowing is a submaximal strength activity, yet older adults have less functional reserve. 4.

    This prospective, single-blinded study investigated the validity and reliability of cervical auscultation (CA) under two conditions; (1) CA-only, using isolated swallow-sound clips, and (2) CSE + CA, using extra clinical swallow examination (CSE) information such as patient case history, oromotor assessment, and the same swallow-sound clips as condition one. The two CA conditions were compared against a fibre-optic endoscopic evaluation of swallowing (FEES) reference test. Each CA condition consisted of 18 swallows samples compiled from 12 adult patients consecutively referred to the FEES clinic. Patients' swallow sounds were simultaneously recorded during FEES via a Littmann E3200 electronic stethoscope. These 18 swallow samples were sent to 13 experienced dysphagia clinicians recruited from the UK and Australia who were blinded to the FEES results. Samples were rated in terms of (1) if dysphagic, (2) if the patient was safe on consistency trialled, and (3) dysphagia severity. Sensitivity measures ranged from 83-95%, specificity measures from 50-92% across the conditions. Intra-rater agreement ranged from 69-97% total agreement. Inter-rater reliability for dysphagia severity showed substantial agreement (rs = 0.68 and 0.74). Results show good rater reliability for CA-trained speech-language pathologists. Sensitivity and specificity for both CA conditions in this study are comparable to and often better than other well-established CSE components.

    Neuromodulation is one option for the management of a wide variety of lower urinary tract disorders, including non-neuropathic and neuropathic bladder dysfunctions. The mechanisms of action of the reported techniques remain unclear; urodynamic changes are minimal, but symptomatic improvements are common. Although the treatment is relatively free from side-effects compared with more aggressive surgical options, the placebo effect is likely to be significant. Its exact cost effectiveness is unclear, but the technology is a welcome addition to the range of treatment options for lower urinary tract dysfunctions, such as urgency and urge incontinence.

    The purpose of this study was to analyze the relationship between oral bacterial colonization and oral motor dysfunction. Oral motor dysfunction (swallowing and speech disorders) and detection of oral bacterial species from dental plaque in 55 elderly persons who had remained hospitalized for more than 3 months were investigated and statistically analyzed. The detection rates of methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, Streptococcus agalactiae, and Stenotrophomonas maltophilia were significantly higher in subjects with than in those without a swallowing disorder. A similar result was found with regard to the presence of a speech disorder. About half of subjects who had oral motor dysfunction and hypoalbuminemia had colonization by MRSA and/or Pseudomonas aeruginosa. These results suggest that the combination of oral motor dysfunction and hypoalbminemia elevated the risk of opportunistic microorganisms colonization in the oral cavity of elderly patients hospitalized over the long term.

    Yawning is a stereotyped motor behavior characterized by deep inhalation and associated dilation of the respiratory tract, pronounced jaw opening, and facial grimacing. The frequency of spontaneous yawning varies over the diurnal cycle, peaking after waking and before sleep. Yawning can also be elicited by seeing or hearing another yawn, or by thinking about yawning, a phenomenon known as "contagious yawning". Yawning is mediated by a distributed network of brainstem and supratentorial brain regions, the components of which are shared with other airway behaviors including respiration, swallowing, and mastication. Nevertheless, the possibility of behavioral coordination between yawning and other brainstem-mediated functions has not been examined. Here we show, with a double-blind methodology, a greater-than-fivefold increase in rest (saliva) swallowing rate during the 10-s period immediately following contagious yawning elicited in 14 adult humans through the viewing of videotaped yawn stimuli. Sixty-five percent of yawns were followed by a swallow within 10 s and swallows accounted for 26 % of all behaviors produced during this post-yawn period. This novel finding of a tight temporal coupling between yawning and swallowing provides preliminary evidence that yawning and swallowing are physiologically related, thus extending current models of upper airway physiology and neurophysiology. Moreover, our finding suggests the possibility that yawning plays a role in eliciting rest swallowing, a view not considered in previous theories of yawning. As such, the present demonstration of a temporal association between yawning and swallowing motivates a re-examination of the longstanding question, "Why do we yawn?".

    Dysphagia is a relevant symptom in Parkinson's disease, whose pathophysiology is poorly understood. It is mainly attributed to degeneration of brainstem nuclei. However, alterations in the cortical contribution to deglutition control in the course of Parkinson's disease have not been investigated. Here, we sought to determine the patterns of cortical swallowing processing in patients with Parkinson's disease with and without dysphagia. Swallowing function in patients was objectively assessed with fiberoptic endoscopic evaluation. Swallow-related cortical activation was measured using whole-head magnetoencephalography in 10 dysphagic and 10 non-dysphagic patients with Parkinson's disease and a healthy control group during self-paced swallowing. Data were analysed applying synthetic aperture magnetometry, and group analyses were done using a permutation test. Compared with healthy subjects, a strong decrease of cortical swallowing activation was found in all patients. It was most prominent in participants with manifest dysphagia. Non-dysphagic patients with Parkinson's disease showed a pronounced shift of peak activation towards lateral parts of the premotor, motor and inferolateral parietal cortex with reduced activation of the supplementary motor area. This pattern was not found in dysphagic patients with Parkinson's disease. We conclude that in Parkinson's disease, not only brainstem and basal ganglia circuits, but also cortical areas modulate swallowing function in a clinically relevant way. Our results point towards adaptive cerebral changes in swallowing to compensate for deficient motor pathways. Recruitment of better preserved parallel motor loops driven by sensory afferent input seems to maintain swallowing function until progressing neurodegeneration exceeds beyond the means of this adaptive strategy, resulting in manifestation of dysphagia.

    The aim of this study was to compare selected parameters of two swallow evaluations: fiberoptic endoscopic evaluation of swallowing (FEES) and the modified barium swallow (MBS) study. This was a cross-sectional, descriptive study. Fifty-five clinicians were asked to watch video recordings of swallow evaluations of 2 patients that were done using fluoroscopy and endoscopy simultaneously. In a randomized order, clinicians viewed 4 edited videos from simultaneous evaluations: the FEES and MBS videos of patient 1 and 2 each taking one swallow of 5 mL applesauce. Clinicians filled out a questionnaire that asked (1) which anatomical sites they could visualize on each video, (2) where they saw pharyngeal residue after a swallow, (3) their overall clinical impression of the pharyngeal residue, and (4) their opinions of the evaluation styles. Clinicians reported a significant difference in the visualization of anatomical sites, 11 of the 15 sites were reported as better-visualized on the FEES than on the MBS video (p < 0.05). Clinicians also rated residue to be present in more locations on the FEES than on the MBS. Clinicians' overall impressions of the severity of residue on the same exact swallow were significantly different depending on the evaluation type (FEES vs. MBS for patient 1 χ(2) = 20.05, p < 0.0001; patient 2 χ(2) = 7.52, p = 0.006), with FEES videos rated more severely. FEES advantages were: more visualization of pharyngeal and laryngeal swallowing anatomy and residue. However, as a result, clinicians provided more severe impressions of residue amount on FEES. On one hand, this suggests that FEES is a more sensitive tool than MBS studies, but on the other hand, clinicians might provide more severe interpretations on FEES.

    Previous research has established that a great deal of variation exists in the temporal sequence of swallowing events for healthy adults. Yet, the impact of aging on swallow event sequence is not well understood. Kendall et al. (Dysphagia 18(2):85-91, 2003) suggested there are 4 obligatory paired-event sequences in swallowing. We directly compared adherence to these sequences, as well as event latencies, and quantified the percentage of unique sequences in two samples of healthy adults: young ( 65). The 8 swallowing events that contribute to the sequences were reliably identified from videofluoroscopy in a sample of 23 healthy seniors (10 male, mean age 74.7) and 20 healthy young adults (10 male, mean age 31.5) with no evidence of penetration-aspiration or post-swallow residue. Chi-square analyses compared the proportions of obligatory pairs and unique sequences by age group. Compared to the older subjects, younger subjects had significantly lower adherence to two obligatory sequences: Upper Esophageal Sphincter (UES) opening occurs before (or simultaneous with) the bolus arriving at the UES and UES maximum distention occurs before maximum pharyngeal constriction. The associated latencies were significantly different between age groups as well. Further, significantly fewer unique swallow sequences were observed in the older group (61%) compared with the young (82%) (χ 2  = 31.8; p < 0.001). Our findings suggest that paired swallow event sequences may not be robust across the age continuum and that variation in swallow sequences appears to decrease with aging. These findings provide normative references for comparisons to older individuals with dysphagia.

    The aim of the present study was to investigate the adaptation of the swallowing reflex in terms of reduced swallowing reflex initiation following continuous superior laryngeal nerve stimulation. Forty-four male Sprague Dawley rats were anesthetized with urethane. To identify swallowing, electromyographic activity of the left mylohyoid and thyrohyoid muscles was recorded. To evoke the swallowing response, the superior laryngeal nerve (SLN), recurrent laryngeal nerve, or cortical swallowing area was electrically stimulated. Repetitive swallowing evoked by continuous SLN stimulation was gradually reduced, and this reduction was dependent on the resting time duration between stimulations. Prior SLN stimulation also suppressed subsequent swallowing initiation. The reduction in evoked swallows induced by recurrent laryngeal nerve or cortical swallowing area stimulation was less than that following superior laryngeal nerve stimulation. Decerebration had no effect on the reduction in evoked swallows. Prior subthreshold stimulation reduced subsequent initiation of swallowing, suggesting that there was no relationship between swallowing movement evoked by prior stimulation and the subsequent reduction in swallowing initiation. Overall, these data suggest that reduced sensory afferent nerve firing and/or trans-synaptic responses, as well as part of the brainstem central pattern generator, are involved in adaptation of the swallowing reflex following continuous stimulation of swallow-inducing peripheral nerves and cortical areas.

    Swallowing difficulties in Parkinson's disease can result in decreased quality of life. The swallowing quality of life questionnaire (SWAL-QOL) is an instrument for specifically assessing quality of life with respect to swallowing, which has been little explored in patients with Parkinson's disease (PD). The goal of this study was to evaluate the quality of life with respect to swallowing in persons with PD compared to controls and at several stages of the disease using the SWAL-QOL. The experimental group was composed of 62 persons with PD at stages 1-4. Forty-one age-matched healthy subjects constituted the control group. The SWAL-QOL scores were significantly lower for the patients with PD than for the controls in all SWAL-QOL domains. Eating duration had the largest difference in score between persons with PD and the controls and the lowest mean score, followed by communication, fatigue, fear, sleep, and food selection. The scores of most domains were lower at later stages of the disease. The scores for eating duration, symptom frequency, and sleep were significantly lower at stage 4 than stages 1 and 2. In conclusion, patients with PD have significantly lower scores in all domains of the SWAL-QOL than normal controls. This means swallowing difficulties occurring in patients with PD negatively affect their QOL. Progression of the disease worsens swallowing QOL, more specifically in the domains of eating duration, symptom frequency, and sleep. This occurs mostly at later stages of the 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.

    Swallowing disorders after stroke or skull base surgery can be life threatening. Although late recovery can occur, it remains poorly documented. We report a case of a 54-year-old woman with dysphagia resulting from a cerebellar stroke with hemorrhage that was evacuated through craniotomy. Swallowing difficulties were assessed by a videoendoscopic swallowing study. She presented with disruption of swallow initiation and impairment of the pharyngeal stage, resulting in hypopharyngeal stasis and penetration with aspiration. Supportive swallowing therapy was conducted with careful reeducation to assist initiation of the pharyngeal stage as well as development of compensatory postural technique. Initial improvement was very slow but became rapidly progressive from the 31st month after the stroke. By the 34th month, oral feeding was possible without aspiration. This case demonstrates that improvement in swallowing function can be expected even 3 years after stroke or skull base surgery. Determination of predictive factors for late functional recovery is of great importance and should be the focus of further investigation.

    Patients with dysphagia, heartburn and chest pain are regularly referred for radiologic evaluation of swallowing. The liquid barium swallow has been of great value for the biphasic evaluation of the pharynx and esophagus. Though many patients complain of dysphagia specifically for solids, solid bolus swallow is ususally not part of the evaluation. For the present study we therefore included the use of a solid bolus with a diameter of 13 mm and interviewed the patients carefully for any symptoms during this tablet swallow. Of 200 patients examined, the tablet passed through the esophagus without delay in 102. In the 98 patients with delayed passage, the solid bolus arrest occurred in the pharynx in 5 and in the esophagus in 93. Arrest in the esophagus was due to esophageal dysmotility in 48 patients. Twenty of these were symptomatic during the tablet swallow. A narrowing was the cause in 45, of whom 9 had symptoms. In 18 patients (9%) the solid bolus added key information to the radiologic evaluation. We therefore recommend that the solid bolus is included in the routine radiologic work-up of patients with dysphagia. Careful attention to symptoms during the tablet swallow is important. (orig.)

    Full Text Available INTRODUCTION: Upper airway nerve and muscle damage associated with obstructive sleep apnea may impair the strength and dynamics of pharyngeal and esophageal contractions during swallowing. OBJECTIVE: To evaluate the presence of alterations in pharyngoesophageal manometry in patients with obstructive sleep apnea with and without oropharyngeal dysphagia. METHODS: 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. RESULTS: 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. CONCLUSION: Pharyngoesophageal manometry detected no statistically significant difference between the groups with and without oropharyngeal dysphagia.

    The process of medical-healthcare technological revolution represents an advantage for the patient and for the care provider, in terms of costs and distances reduction. The telehomecare approach could be useful for monitoring the swallowing disorder in neurodegenerative diseases, preventing complications. In this study the applicability of telemedicine techniques for the monitoring of swallowing function, in patients affected by Huntington's disease (HD), was evaluated through the acquisition and analysis of the sound of swallowing. Two patients with HD were outpatient screened for dysphagia through the Bedside Swallowing Assessment Scale (BSAS) sensitized with pulse oximetry and cervical auscultation. Subsequently, the swallowing functionality was telemonitored for three months with Skype. The swallowing sounds were acquired with a detection microphone attached to the lateral edge of the trachea during fluid intake. The sounds were instantly processed and graphically represented through the Praat software. The analysis of the acoustic signal acquired remotely has made it possible to identify the situations that required immediate speech therapy intervention, suggesting to the patients further modifications of food consistencies, and saving frequent moving to the hospital even in the absence of critical situations. Remote assistance applied to speech therapy could represent a benefit for patients and their carers and a more efficient use of medical and health resources.

    Little is documented about contemporary management of speech and swallowing disorders associated with paediatric acquired brain injury (ABI). It is therefore challenging for clinicians in this field to benchmark their clinical management against current evidence or practices undertaken in other centres. To address this issue, we aimed to provide much-needed baseline data on speech and language pathology management of speech and swallowing disorders associated with childhood ABI. Key objectives were to: (i) determine whether clinicians use formalized referral criteria, clinical guidelines, protocols or care pathways; and (ii) to document the specific assessment and treatment approaches used. Speech and language pathology managers and clinicians at 31 major paediatric rehabilitation centres across Australia, New Zealand, the UK and Ireland were invited to participate in an online survey. Fifty-one speech and language pathologists responded representing 26 centres (84% response rate). Routine referrals of ABI patients to speech and language pathology occurred relatively infrequently in these centres (12%). Centres utilized assessment protocols (23%) and guidelines (35%) more frequently than treatment guidelines (8%). Multidisciplinary care pathways were applied by 31%. Most centres used adult-based motor speech assessments and informal ('in-house developed') swallowing assessment tools. The limited use of referral criteria, protocols, care pathways and guidelines invites the possibility of unequal care, and less than optimal outcomes. Reliance on adult-based or in-house assessments is inappropriate, yet frequently a necessity due to an absence of paediatric-specific tools in this field. Further research is required in parallel with the formation of consensus groups to support the development of: (i) paediatric-specific assessment tools and management approaches; and (ii) clinical protocols and guidelines. © 2010 Blackwell Publishing Ltd.

  3. ERS statement on the multidisciplinary respiratory management of ataxia telangiectasia

    2015-12-01

    Full Text Available Ataxia telangiectasia (A-T is a rare, progressive, multisystem disease that has a large number of complex and diverse manifestations which vary with age. Patients with A-T die prematurely with the leading causes of death being respiratory diseases and cancer. Respiratory manifestations include immune dysfunction leading to recurrent upper and lower respiratory infections; aspiration resulting from dysfunctional swallowing due to neurodegenerative deficits; inefficient cough; and interstitial lung disease/pulmonary fibrosis. Malnutrition is a significant comorbidity. The increased radiosensitivity and increased risk of cancer should be borne in mind when requesting radiological investigations. Aggressive proactive monitoring and treatment of these various aspects of lung disease under multidisciplinary expertise in the experience of national multidisciplinary clinics internationally forms the basis of this statement on the management of lung disease in A-T. Neurological management is outwith the scope of this document.

    Dosimetric analysis measurements of the Dose-Area-Product (DAP) of 7 individuals were estimated for the deglutition dynamic using the videofluoroscopic method. The aim of this study is to establish in a preliminary way, typical DAP values for this kind of study. The DAP values were obtained attaching to the X ray tube exit, an ionization chamber from PTW and a Diamentor M4 meter. The typical DAP values obtained during the videofluoroscopic evaluation of the deglutition dynamic, including its three phases, was: 4101 ± 881 cGy.cm 2 and the typical DAP rate was 577 ± 94 cGy.cm 2 /min. These values refer to a standard patient (1.57 cm height, 56 kg. weight) and a protocol that can be performed in about 7 minutes. The values, defined herein as typical refer to the used protocol. To our knowledge, the mean DAP rate is a good parameter to estimate radiation exposure from videofluoroscopic study of swallowing process. (author)

    Job-related burnout and distress are adverse stress responses which affect individuals in their occupational environment. This study aimed at investigating the effect of a rational-emotive stress management program on job burnout and dysfunctional distress among special education teachers in Nigeria. A pretest-posttest randomized control group design was used. The participants in the study were 54 special education teachers. Data were collected using self-report questionnaires. Participants were allocated to either the treatment group (n = 28 [59.1%]) or the waitlist control group (n = 26 [48.1%]), respectively. A rational-emotive stress management manual was used to deliver the intervention. We statistically analyzed the data collected at three-time points with repeated-measures analysis of variance. At baseline, the job-related burnout symptoms and distress scores of participants were high. However, an intention-to-treat analysis showed that the rational-emotive stress management intervention program was efficacious in reducing the levels of job-related burnout symptoms and dysfunctional distress among participants assigned to the treatment group, compared to a waitlisted group at post-treatment and follow-up meetings. Our study demonstrates the effectiveness of a rational-emotive stress management intervention in reducing the level of job-related burnout and distress in a sample of special education teachers in Nigeria. Occupational health counsellors and other clinicians with sufficient knowledge of rational-emotive behavior therapy framework are urged to employ this approach in assisting other employees in managing job burnout symptoms, and distress.

    The incidence of head and neck cancer (HNC) in the UK is rising, with an average of 31 people diagnosed daily. Patients affected by HNC suffer significant short-term and long-term post-treatment morbidity as a result of dysphagia, which affects daily functioning and quality of life (QOL). Pretreatment swallowing exercises may provide additional benefit over standard rehabilitation in managing dysphagia after primary HNC treatments, but uncertainty about their effectiveness persists. This study was preceded by an intervention development phase to produce an optimised swallowing intervention package (SIP). The aim of the current study is to assess the feasibility of this new intervention and research processes within a National Health Service (NHS) setting. A two-arm non-blinded randomised controlled feasibility study will be carried out at one tertiary referral NHS centre providing specialist services in HNC. Patients newly diagnosed with stage III and IV disease undergoing planned surgery and/or chemoradiation treatments will be eligible. The SIP will be delivered pre treatment, and a range of swallowing-related and QOL measures will be collected at baseline, 1, 3 and 6 months post-treatment. Outcomes will test the feasibility of a future randomised controlled trial (RCT), detailing rate of recruitment and patient acceptance to participation and randomisation. Salient information relating to protocol implementation will be collated and study material such as the case report form will be tested. A range of candidate outcome measures will be examined for suitability in a larger RCT. Ethical approval was obtained from an NHS Research Ethics Committee. Findings will be published open access in a peer-reviewed journal, and presented at relevant conferences and research meetings. ISRCTN40215425; Pre-results.

  8. Gamma radiation effects on nestling Tree Swallows

    Zach, R.; Mayoh, K.R.

    1984-01-01

    The sensitivity of Tree Swallows (Tachycineta bicolor) to the stress of ionizing radiation was investigated with growth analysis. Freshly hatched nestlings were temporarily removed from nests, taken to the laboratory and acutely exposed to 0.9, 2.7, or 4.5 Gy gamma radiation. Some of the unirradiated control nestlings were also taken to the laboratory whereas others were left in the nests. Growth of all the nestlings was measured daily and analyzed by fitting growth models. There was no detectable radiation-induced mortality up to fledgling, approx. = 20 d after irradiation. Radiation exposure did not affect the basic growth pattern; the logistic growth model was most suitable for body mass and foot length, and the von Bertalanffy model for primary-feather length, irrespective of treatment. Parameter values from these models indicated pronounced growth depression in the 2.7-Gy and 4.5-Gy groups, particularly for body mass. Radiation also affected the timing of development. The growth depression of the 2.7-Gy group was similar to that caused by hatching asynchrony in unirradiated nestlings. The 4.5-Cy nestlings grew as well as unexposed nestlings that died from natural causes. Chronic irradiation at approx. = 1.0 Cy/d caused more severe growth effects than acute exposure to 4.5 Gy and may have caused permanent stunting. Growth analysis is a potent tool for assessing man-made environmental stresses. Observed body-mass statistics and model parameters seem to be most sensitive to environmental stresses, but coefficients of variation are not necessarily correlated with sensitivity. 34 references, 2 figures, 4 tables

  9. The effect of two different glycemic management protocols on postoperative cognitive dysfunction in coronary artery bypass surgery

    Full Text Available Abstract Introduction: Postoperative cognitive dysfunction (POCD is an adverse outcome of surgery that is more common after open heart procedures. The aim of this study is to investigate the role of tightly controlled blood glucose levels during coronary artery surgery on early and late cognitive decline. Methods: 40 patients older than 50 years undergoing elective coronary surgery were randomized into two groups. In the "Tight Control" group (GI, the glycemia was maintained between 80 and 120 mg dL-1 while in the "Liberal" group (GII, it ranged between 80-180 mg dL-1. A neuropsychological test battery was performed three times: baseline before surgery and follow-up first and 12th weeks, postoperatively. POCD was defined as a drop of one standard deviation from baseline on two or more tests. Results: At the postoperative first week, neurocognitive tests showed that 10 patients in the GI and 11 patients in GII had POCD. The incidence of early POCD was similar between groups. However the late assessment revealed that cognitive dysfunction persisted in five patients in the GII whereas none was rated as cognitively impaired in GI (p = 0.047. Conclusion: We suggest that tight perioperative glycemic control in coronary surgery may play a role in preventing persistent cognitive impairment.

    To study mastication and swallowing disorders in patients with temporomandibular disorders (TMD). To investigate mastication and swallowing disorders in patients with severe TMD referred to surgery. Clinical and experimental study involving ten individuals with TMD submitted to deglutition videofluoroscopy. These patients did not have posterior teeth, mastication pain and food replacement in favor of pasty consistence food. The assessment of the oral and pharyngeal phases approached the following aspects: side of onset and preferential side for chewing, premature escape, remains of food residues in the oral cavity or in the pharyngeal recesses, number of necessary swallowing efforts, laryngeal penetration and/or tracheal aspiration. During mastication and the oral phase we observed tongue compensatory movements upon chewing (n = 7; 70%), premature escape (n = 4; 40%), food remains in the cavity after swallowing (n = 5; 50%) and an excessive number of deglutition efforts (n = 5; 50%). On the pharyngeal phase we observed food remains in the valleculae (n = 6; 60%), in the pyriform sinuses (n = 4; 40%); laryngeal penetration (n = 1; 10%) and tracheal aspiration (n = 4; 40%). TMD patients may have alterations in their chewing and swallowing patterns, with laryngeal penetration and/or tracheal aspiration. The study indicates the need for a multidisciplinary assessment because of dysphagia in TMD patients.

    Autoimmune connective tissue diseases are a heterogeneous group of pathologies that affect about 10% of world population with chronic evolution in 20%–80%. Inflammation in autoimmune diseases may lead to serious damage to other organs including the gastrointestinal tract. Gastrointestinal tract involvement in these patients may also due to both a direct action of antibodies against organs and pharmacological therapies. Dysphagia is one of the most important symptom, and it is caused by failure of the swallowing function and may lead to aspiration pneumonia, malnutrition, dehydration, weight loss, and airway obstruction. The videofluorographic swallowing study is a key diagnostic tool in the detection of swallowing disorders, allowing to make an early diagnosis and to reduce the risk of gastrointestinal and pulmonary complications. This technique helps to identify both functional and structural anomalies of the anatomic chain involved in swallowing function. The aim of this review is to systematically analyze the basis of the pathological involvement of the swallowing function for each rheumatological disease and to show the main features of the videofluorographic study that may be encountered in these patients.

    Our goal was to study deglutition of Parkinson's disease (PD) patients and normal controls (NC) using surface electromyography (sEMG). The study included 15 patients with idiopathic PD and 15 age-matched normal controls. Surface electromyography was collected over the suprahyoid muscle group. Conditions were the following: swallow at once 10 and 20 ml of water and 5 and 10 ml of yogurt of firm consistency, and freely drink 100 ml of water. During swallowing, durations of sEMG were significantly longer in PD patients than in normal controls but no significant differences of amplitudes were found. Eighty percent of the PD patients and 20 % of the NC needed more than one swallow to consume 20 ml of water, while 70 % of the PD patients and none of the NC needed more than one swallow to consume 5 ml of yogurt. PD patients took significantly more time and needed significantly more swallows to drink 100 ml of water than normal controls. We conclude that sEMG might be a simple and useful tool to study and monitor deglutition in PD patients.

  13. A procedure for denoising dual-axis swallowing accelerometry signals

    2010-01-01

    Dual-axis swallowing accelerometry is an emerging tool for the assessment of dysphagia (swallowing difficulties). These signals however can be very noisy as a result of physiological and motion artifacts. In this note, we propose a novel scheme for denoising those signals, i.e. a computationally efficient search for the optimal denoising threshold within a reduced wavelet subspace. To determine a viable subspace, the algorithm relies on the minimum value of the estimated upper bound for the reconstruction error. A numerical analysis of the proposed scheme using synthetic test signals demonstrated that the proposed scheme is computationally more efficient than minimum noiseless description length (MNDL)-based denoising. It also yields smaller reconstruction errors than MNDL, SURE and Donoho denoising methods. When applied to dual-axis swallowing accelerometry signals, the proposed scheme exhibits improved performance for dry, wet and wet chin tuck swallows. These results are important for the further development of medical devices based on dual-axis swallowing accelerometry signals. (note)

    2015-01-01

    Purpose of Review: This article highlights the dissociable human memory systems of episodic, semantic, and procedural memory in the context of neurologic illnesses known to adversely affect specific neuroanatomic structures relevant to each memory system. Recent Findings: Advances in functional neuroimaging and refinement of neuropsychological and bedside assessment tools continue to support a model of multiple memory systems that are distinct yet complementary and to support the potential for one system to be engaged as a compensatory strategy when a counterpart system fails. Summary: Episodic memory, the ability to recall personal episodes, is the subtype of memory most often perceived as dysfunctional by patients and informants. Medial temporal lobe structures, especially the hippocampal formation and associated cortical and subcortical structures, are most often associated with episodic memory loss. Episodic memory dysfunction may present acutely, as in concussion; transiently, as in transient global amnesia (TGA); subacutely, as in thiamine deficiency; or chronically, as in Alzheimer disease. Semantic memory refers to acquired knowledge about the world. Anterior and inferior temporal lobe structures are most often associated with semantic memory loss. The semantic variant of primary progressive aphasia (svPPA) is the paradigmatic disorder resulting in predominant semantic memory dysfunction. Working memory, associated with frontal lobe function, is the active maintenance of information in the mind that can be potentially manipulated to complete goal-directed tasks. Procedural memory, the ability to learn skills that become automatic, involves the basal ganglia, cerebellum, and supplementary motor cortex. Parkinson disease and related disorders result in procedural memory deficits. Most memory concerns warrant bedside cognitive or neuropsychological evaluation and neuroimaging to assess for specific neuropathologies and guide treatment. PMID:26039844

    Head and neck cancer (HNC) is the sixth most common cancer worldwide, and the functional, psychological and social consequences of HNC cancer and its treatment can be severe and chronic. Dysphagia (swallowing problems) affects up to two thirds of patients undergoing combined chemoradiotherapy. Recent reviews suggest that prophylactic swallowing exercises may improve a range of short- and long-term outcomes; however, the importance of psychological and behavioural factors on adherence to swallowing exercises has not been adequately studied. This study aims to develop and test the feasibility of a Swallowing intervention Package (SiP) designed in partnership with patients, speech and language therapists (SLTs) and other members of the head and neck multi-disciplinary team (MDT), for patients undergoing chemoradiotherapy (CRT) or radiotherapy (RT) for head and neck cancer. This feasibility study uses quantitative and qualitative research methods, within a quasi-experimental design, to assess whether patients will tolerate and adhere to the SiP intervention, which aspects of the intervention can be implemented and which cannot, whether treatment fidelity can be achieved across different contexts, whether study processes and outcome measures will be feasible and acceptable and to what extent the intervention is likely to have an impact on swallowing dysfunction and quality of life. Patients are being recruited from five sites in Scotland and England (three interventions and two usual care). The SLT based in the relevant intervention centre teaches the exercise programme and provides supporting materials. A combination of patient-reported outcome measures (PROMs), adherence measures and clinical swallowing assessments are used prior to intervention (baseline), at the end of treatment, 3 and 6 months post-treatment. This collaborative study has taken a unique approach to the development of a patient-centred and evidence-based swallowing intervention. The introduction of

    The majority of swallowed foreign bodies are thrown spontaneously without causing complications in the digestive system. Multiple number of foreign bodies may be swallowed by psychiatric patients which delay diagnosis and increase the complication rate. Long and hard objects cannot pass through the pylorus, and may cause obstruction, ulceration, bleeding and perforation. Endoscopy is used as an effective method in such cases. An exploratory laparatomy was performed after unsuccessful endoscopic foreign object removal in a 28-year-old schizophrenic patient with gastric outlet obstruction due to multiple cigarette lighter swallowing. Ten lighters were removed from the stomach through gastrotomy and one more lighter was removed from the descending colon by milking through the anus. The aim of this paper is to discuss encountered difficulties in psychiatric patients who underwent surgery due to intake of foreign bodies.

    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.

    Traumatic brain injury and subarachnoid haemorrhage are important causes of morbidity and mortality in the developed world. There is a large body of evidence that demonstrates that both conditions may adversely affect pituitary function in both the acute and chronic phases of recovery. Diagnosis of hypopituitarism and accurate treatment of pituitary disorders offers the opportunity to improve mortality and outcome in both traumatic brain injury and subarachnoid haemorrhage. In this article, we will review the history and pathophysiology of pituitary function in the acute phase following traumatic brain injury and subarachnoid haemorrhage, and we will discuss in detail three key aspects of pituitary dysfunction which occur in the early course of TBI; acute cortisol deficiency, diabetes insipidus and SIAD.

    Full Text Available Context Videofluoroscopic swallowing study is a dynamic exam and allows the evaluation of the complete swallowing process. However, most published studies have only reported alterations in the oropharynx and pharyngoesophageal transition, leaving the analysis of the esophagus as a secondary goal. Objectives The goal of this study was to investigate the prevalence of alterations in the esophageal phase thorough videofluoroscopic swallowing study in patients with dysphagia. Methods Consecutive patients with dysphagia who underwent videofluoroscopic swallowing study including esophageal analysis between May 2010 and May 2012 had their exams retrospectively reviewed. Patients were classified into two groups: Group I - without a pre-established etiological diagnosis and Group II - with neurological disease. During the exam, the patients ingested three different consistencies of food (liquid, pasty and solid contrasted with barium sulfate and 19 items were analyzed according to a protocol. The esophageal phase was considered abnormal when one of the evaluated items was compromised. Results Three hundred and thirty-three (n = 333 consecutive patients were studied - 213 (64% in Group I and 120 (36% in Group II. Esophageal alterations were found in 104 (31% patients, with a higher prevalence in Group I (36.2%, especially on the items esophageal clearance (16.9% and tertiary contractions (16.4%. It was observed that 12% of individuals in Group I only presented alterations on the esophageal phase. Conclusion Evaluation of the esophageal phase of swallowing during videofluoroscopic swallowing study detects abnormalities in patients with cervical dysphagia, especially in the group without pre-established etiological diagnosis.

  20. Cortical recovery of swallowing function in wound botulism

    2008-05-01

    Full Text Available Abstract Background Botulism is a rare disease caused by intoxication leading to muscle weakness and rapidly progressive dysphagia. With adequate therapy signs of recovery can be observed within several days. In the last few years, brain imaging studies carried out in healthy subjects showed activation of the sensorimotor cortex and the insula during volitional swallowing. However, little is known about cortical changes and compensation mechanisms accompanying swallowing pathology. Methods In this study, we applied whole-head magnetoencephalography (MEG in order to study changes in cortical activation in a 27-year-old patient suffering from wound botulism during recovery from dysphagia. An age-matched group of healthy subjects served as control group. A self-paced swallowing paradigm was performed and data were analyzed using synthetic aperture magnetometry (SAM. Results The first MEG measurement, carried out when the patient still demonstrated severe dysphagia, revealed strongly decreased activation of the somatosensory cortex but a strong activation of the right insula and marked recruitment of the left posterior parietal cortex (PPC. In the second measurement performed five days later after clinical recovery from dysphagia we found a decreased activation in these two areas and a bilateral cortical activation of the primary and secondary sensorimotor cortex comparable to the results seen in a healthy control group. Conclusion These findings indicate parallel development to normalization of swallowing related cortical activation and clinical recovery from dysphagia and highlight the importance of the insula and the PPC for the central coordination of swallowing. The results suggest that MEG examination of swallowing can reflect short-term changes in patients suffering from neurogenic dysphagia.

    The primary objective of this study was to investigate the quality of life (QOL) of patients with oral squamous cell carcinoma (OSCC) undergoing curative neoadjuvant chemoradiotherapy followed by radical tumour resection and simultaneous oral cavity reconstruction, using two validated questionnaires. A secondary objective was to assess clinical variables predicting post-treatment dysfunction in chewing, saliva, and swallowing. Thirty-five patients with locally advanced OSCC who underwent preoperative chemoradiotherapy were recruited prospectively. All patients completed both the University of Washington Quality of Life version 4 questionnaire (UW-QOL) and the Functional Assessment of Cancer Therapy-Head & Neck version 4 questionnaire (FACT-H&N). UW-QOL and FACT-H&N items were associated with clinical variables. Nearly three-quarters of OSCC patients perceived good to excellent levels of overall QOL after preoperative chemoradiotherapy. Chewing difficulties, decreased salivary function, and swallowing dysfunction were the most frequent complaints of OSCC patients. Items related to food intake were significantly worse in OSCC patients older than 60 years and those with T4 tumours, as well as those without alcohol intake. Chewing, saliva, and swallowing are the most significant issues in patients with OSCC undergoing preoperative chemoradiotherapy. The results of this study may help guide treatment decisions for OSCC patients based on more accurate expectations of adverse effects of cancer treatment.

    Forty-four patients with dysphagia were examined both by endoscopy and by barium swallow with a marshmallow bolus. In these patients 36 stenoses were found: 34 by radiology and 30 by endoscopy. The radiologic criteria for stenosis included arrest of the marshmallow in a manner to support a column of barium and reproduction of the patient's symptoms at the time this occurred. Radiologic false negative findings were partly due to an inability by patients to swallow an adequate marshmallow bolus; endoscopic failures were associated with small endoscopes and mild stenoses.

    Infants with bilateral vocal fold immobility (BVFI) often have poor swallow function in addition to potential airway compromise. While there are several reports on BVFI and its effect on patients' airway status, little is known about long term swallow function. We aim to characterize the swallowing function over time in pediatric patients with bilateral vocal fold immobility. A retrospective review of medical records of infants diagnosed with BVFI at a tertiary care children's hospital between 2005 and 2014 was conducted. Patient demographics, nature and etiology of immobility, laryngoscopy findings, comorbidities, and swallow outcomes at diagnosis and follow-up were recorded. Swallowing outcomes as measured by presence or absence of a gastrostomy tube were compared by etiology, vocal fold status, and normal or developmentally delay using the Fisher's exact test. 110 patients with a diagnosis of vocal fold immobility were identified. Twenty-nine (26%) had BVFI and twenty-three had complete medical records. Etiologies of vocal fold immobility include cardiac related in 13% (3/23), idiopathic in 30% (7/23) prolonged intubation in 26% (6/23) central neurologic in 22% (5/23), trauma in 4% (1/23), and infection in 4% (1/23). Average follow-up time was 44 months (range 5-94 months). Ten patients (56.5%) required a gastrostomy tube at time of diagnosis. Of this cohort who received gastrostomy tubes, three (30%) ultimately transitioned to complete oral feeds. Return of vocal fold mobility did not correlate with swallow function. In those with non-neurologic etiologies, the need for gastrostomy tube at end of follow up was unlikely. There was a statistically significant difference in the percentage of gastrostomy tube-free children at most recent follow up in patients who were normally developed (86%) versus those who were developmentally delayed (33%) (p = 0.02). We characterized the swallowing function of 23 pediatric patients with BVFI. Comorbidities are significant

    To perform acoustic analysis of swallowing sounds, using a microphone and a notebook computer system, in healthy subjects and patients with dysphagia affected by neurological diseases, testing the positive/negative predictive value of a pathological pattern of swallowing sounds for penetration/aspiration. Diagnostic test study, prospective, not blinded, with the penetration/aspiration evaluated by fibreoptic endoscopy of swallowing as criterion standard. Data from a previously recorded database of normal swallowing sounds for 60 healthy subjects according to gender, age, and bolus consistency was compared with those of 15 patients with dysphagia from a university hospital referral centre who were affected by various neurological diseases. Mean duration of the swallowing sounds and post-swallowing apnoea were recorded. Penetration/aspiration was verified by fibreoptic endoscopy of swallowing in all patients with dysphagia. The mean duration of swallowing sounds for a liquid bolus of 10 ml water was significantly different between patients with dysphagia and healthy patients. We also described patterns of swallowing sounds and tested the negative/positive predictive values of post-swallowing apnoea for penetration/aspiration verified by fibreoptic endoscopy of swallowing (sensitivity 0.67 (95% confidence interval 0.24-0.94); specificity 1.00 (95% confidence interval 0.56-1.00)). The proposed technique for recording and measuring swallowing sounds could be incorporated into the bedside evaluation, but it should not replace the use of more diagnostic and valuable measures.

    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.

    Aim: To investigate the diagnostic yield of T2-weighted magnetic resonance imaging (MRI) screening for vestibular schwannoma and other relevant conditions in the setting of audiovestibular symptoms, given the more liberal contemporary referral criteria. To determine whether presenting clinical symptoms correlate with imaging outcome in order to guide future protocols for MRI referral. Materials and methods: Eight hundred and eighty-one consecutive MRI examinations performed in patients with audiovestibular dysfunction were reviewed. Clinical indications and findings were recorded. Case notes were reviewed in patients with positive imaging findings. Two-way, cross-tabulation, Chi-square analysis was performed to assess the relationship between presenting symptoms and imaging outcome. Results: Twelve of the 881 (1.4%) were positive for vestibular schwannoma. A further four of 881 (0.4%) revealed other relevant conditions. Incidental conditions, felt to be irrelevant to the presenting symptoms, were noted in 12 of the 881 (1.4%). In all 12 cases that were positive for vestibular schwannoma, either tinnitus or hearing loss was present. Conclusion: The yield for T2-weighted MRI to diagnose vestibular schwannoma and other relevant retrocochlear conditions was lower than for previous studies, which is likely to reflect trends in referral criteria. No single audiovestibular symptom or combination of symptoms is a statistically significant predictor of imaging outcome.

    To explore adolescents' struggles with taking oral medications. Copenhagen, Denmark. Semi-structured qualitative interviews were conducted with 89 adolescents (33 boys, 56 girls) between the ages of 11 and 20. Adolescents were recruited through four public schools. To identify struggles with taking oral medication, interview transcripts were systematically searched for statements including the terms swallow, chew, crush and eat. Thematic analysis of the identified statements was carried out to reveal dominant themes in the adolescents' accounts. Over one-third of the adolescents spontaneously provided accounts of the difficulties they experienced with taking oral medications, especially with swallowing tablets. Three themes were dominant in their narratives: barriers, strategies and learning. Barriers experienced by the adolescents involved the medications' properties, e.g. taste. Adolescents developed strategies to overcome these barriers, e.g. crushing tablets. Via a process of learning-by-doing and the acquisition of increased experience and autonomy, many adolescents mastered the skill of swallowing tablets. Many adolescents experienced barriers in their attempts to swallow tablets. They developed various strategies to overcome these barriers and gradually mastered taking medicines in a learning-by-doing process.

    Aim: The aim of our study was to assess the availability of videofluoroscopy to examine patients with swallowing disorders in Austria. Materials and methods: A questionnaire was sent to the department heads of the radiology departments of all hospitals (n=143) and to all non-hospital-based radiologic practices (n=226) throughout Austria. The survey focused on the availability of videofluoroscopic swallowing studies and on the studies performed in patients with deglutition disorders. Results: The questionnaire was completed and returned by 134 of 143 radiology departments (94%) and 65 of 226 non-hospital-based radiologists (29%). Videofluoroscopic swallowing studies were performed in 38 of 134 radiology departments (28%) and in 21 of 65 practices (32%). The method is available in all nine Austrian states (100%) and 27 of 99 districts (27%). The number of examinations performed in different states ranged from 0.7 to 19 studies/10,000 population per year. The number of videofluoroscopic examinations per department or practice in the year 2001 ranged between 5 and 690 (median, 100 examinations). To 85% of videofluoroscopy units patients were referred from otorhinolaryngology/phoniatrics-logopedics, to 69% of videofluoroscopy units referrals were also from internal medicine, from neurology in 54%, and from pediatrics in 20%. Conclusion: Despite the widespread availability of videofluoroscopy throughout Austria, its use still varies largely between different states. The data show that in general there is a wide-spread demand for videofluoroscopic swallowing studies

    Dysphagia and associated aspiration pneumonia are commonly reported sequelae of Parkinson's disease (PD). Previous studies of swallowing in patients with PD have described prolonged pharyngeal transit time, delayed onset of pharyngeal transit, cricopharyngeal (CP) achalasia, reduced pharyngeal constriction, and slowed hyolaryngeal elevation. These studies were completed using inconsistent evaluation methodology, reliance on qualitative analysis, and a lack of a large control group, resulting in concerns regarding diagnostic precision. The purpose of this study was to investigate swallowing function in patients with PD using a norm-referenced, quantitative approach. This retrospective study includes 34 patients with a diagnosis of PD referred to a multidisciplinary voice and swallowing clinic. Modified barium swallow studies were performed using quantitative measures of pharyngeal transit time, hyoid displacement, CP sphincter opening, area of the pharynx at maximal constriction, and timing of laryngeal vestibule closure relative to bolus arrival at the CP sphincter. Reduced pharyngeal constriction was found in 30.4%, and a delay in airway closure relative to arrival of the bolus at the CP sphincter was the most common abnormality, present in 62% of patients. Previously reported findings of prolonged pharyngeal transit, poor hyoid elevation, and CP achalasia were not identified as prominent features. © The Author(s) 2015.

    2015-04-01

    The term presbyphagia refers to all changes of swallowing physiology that are manifested with increasing age. Alterations in the pattern of deglutition that are part of healthy aging are called primary presbyphagia. Primary presbyphagia is not an illness in itself but contributes to a more pervasive naturally diminished functional reserve, making older adults more susceptible to dysphagia. If disorders in swallowing occur in the elderly as a comorbidity of a specific disease, for example stroke or neurodegenerative disorders, this is called secondary presbyphagia. Increasing age has an impact on each stage of deglutition. In the oral preparatory phase a diminished input for smell and taste as well as a usually multifactorial cause of dry mouth are the most important influencing factors. Sarcopenia, the degenerative loss of skeletal muscle mass, strength and quality associated with aging, interferes in particular with the oropharyngeal phase. A decreased sensory feedback from the oropharyngeal mucosa leads to a delayed triggering of the swallowing reflex. Finally, a reduction in connective tissue elasticity and changes of the axial skeleton lead to various modifications of the swallowing pattern with advanced age.

  16. Differences in Swallowing between High and Low Concentration Taste Stimuli

    Full Text Available Taste is a property that is thought to potentially modulate swallowing behavior. Whether such effects depend on taste, intensity remains unclear. This study explored differences in the amplitudes of tongue-palate pressures in swallowing as a function of taste stimulus concentration. Tongue-palate pressures were collected in 80 healthy women, in two age groups (under 40, over 60, stratified by genetic taste status (nontasters, supertasters. Liquids with different taste qualities (sweet, sour, salty, and bitter were presented in high and low concentrations. General labeled magnitude scale ratings captured perceived taste intensity and liking/disliking of the test liquids. Path analysis explored whether factors of taste, concentration, age group, and/or genetic taste status impacted: (1 perceived intensity; (2 palatability; and (3 swallowing pressures. Higher ratings of perceived intensity were found in supertasters and with higher concentrations, which were more liked/disliked than lower concentrations. Sweet stimuli were more palatable than sour, salty, or bitter stimuli. Higher concentrations elicited stronger tongue-palate pressures independently and in association with intensity ratings. The perceived intensity of a taste stimulus varies as a function of stimulus concentration, taste quality, participant age, and genetic taste status and influences swallowing pressure amplitudes. High-concentration salty and sour stimuli elicit the greatest tongue-palate pressures.

    Hiatal hernia (HH) is common in the bariatric population. Its presence imposes various degrees of difficulty in performing laparoscopic sleeve gastrectomy (LSG). Preoperative upper gastrointestinal evaluation consists of fluoroscopic and or endoscopic studies OBJECTIVES: To evaluate the efficacy of routine, preoperative barium swallow in identifying HH in patients undergoing LSG, and determine if such foreknowledge changes operative and immediate postoperative course regarding operative time, intraoperative adverse events, and length of hospital stay (LOS). In addition, to quantify HH prevalence in these patients and correlate preoperative patient characteristics with its presence. High-volume bariatric practice in a private hospital in Israel METHODS: Retrospective analysis of prospectively collected data between October 2010 and March 2015: anthropometrics, co-morbidities, previous barium swallow, preoperative HH workup (type and result), operative and immediate postoperative course. Primary LSG was performed in 2417 patients. The overall prevalence of HH was 7.3%. Preoperative diagnosis of gastroesophageal reflux disease and female gender were independent risk factors for HH presence. Operative times were significantly longer when HH was concomitantly repaired but "foreknowledge" thereof did not assist in shortening this time. Looking for an HH that was suggested in preoperative upper gastrointestinal evaluation slightly prolonged surgery. LOS was not changed in a significant fashion by HH presence and repair, whether suspected or incidentally found. Routine, pre-LSG barium swallow does not seem to offer an advantage over selective intraoperative hiatal exploration, in the discovery and management of HH. Conversely, when preoperative workup yields a false-positive result, surgery is slightly prolonged. Copyright © 2016 American Society for Bariatric Surgery. Published by Elsevier Inc.

    A 63-year-old woman with end-stage renal disease on maintenance hemodialysis discontinued her medication for rheumatoid arthritis with prednisolone and azathioprine. One month later, she was admitted because of consciousness disturbance and right hemiparesis. Diffusion-weighted brain magnetic resonance imaging (MRI) revealed multiple hyperintensities in her left frontal and parietal lobes. She also developed high fever and left neck pain. Carotid ultrasonography showed calcified plaque with vessel wall swelling at the bifurcation of the left common carotid artery (LCCA) and surrounding hypoechoic soft tissue. The tissue was identified as an isodense lesion on noncontrast computed tomography (CT) and as a high-intensity lesion on fat-saturated T2-weighted MRI. From her symptoms and radiological findings, she was diagnosed with carotidynia. Cervical MRI also showed that the LCCA was transposed to a retropharyngeal location, suggesting a moving carotid artery. Carotid ultrasonography revealed that the LCCA moved to and from the retropharyngeal position with swallowing and was thus being compressed by the hyoid bone. After corticosteroid therapy was initiated with 30 mg of prednisolone, her symptoms and radiological findings improved. To our knowledge, this is the first report of a case of cerebral embolism due to carotidynia. The repetitive compressions by the hyoid bone during swallowing were presumed to have provoked shear stress and inflammation of the carotid vessel wall, which was aggravated by discontinuation of steroid therapy in our case. These mechanical and inflammatory stresses might cause dysfunction of endothelial cells, hypercoagulation, platelet hyperaggregation, and vulnerability and rupture of carotid plaques, and may subsequently result in embolic strokes.

    The motor deficits which characterise the sporadic form of Parkinson's disease arise from age-related loss of a subset of dopamine neurons in the substantia nigra. Although motor symptoms respond to dopamine replacement therapies, the underlying disease process remains. This review details some features of the progressive molecular pathology and proposes deployment of a combination of nutrients: R-lipoic acid, acetyl-l-carnitine, ubiquinol, melatonin (or receptor agonists) and vitamin D3, with the collective potential to slow progression of these features. The main nutrient targets include impaired mitochondria and the associated oxidative/nitrosative stress, calcium stress and impaired gene transcription induced by pathogenic forms of alpha- synuclein. Benefits may be achieved via nutrient influence on epigenetic signaling pathways governing transcription factors for mitochondrial biogenesis, antioxidant defences and the autophagy-lysosomal pathway, via regulation of the metabolic energy sensor AMP activated protein kinase (AMPK) and the mammalian target of rapamycin mTOR. Nutrients also benefit expression of the transcription factor for neuronal survival (NR4A2), trophic factors GDNF and BDNF, and age-related calcium signals. In addition a number of non-motor related dysfunctions in circadian control, clock genes and associated metabolic, endocrine and sleep-wake activity are briefly addressed, as are late-stage complications in respect of cognitive decline and osteoporosis. Analysis of the network of nutrient effects reveals how beneficial synergies may counter the accumulation and promote clearance of pathogenic alpha-synuclein. Crown Copyright © 2017.

    Complete pharyngoesophageal strictures may be encountered by the otolaryngologist as a consequence of radiation/chemoradiotherapy therapies for head and neck cancer. A combined anterograde and retrograde dilation procedure (rendezvous procedure) has proven to be a useful surgical intervention in these cases. We assess the long-term swallowing outcomes of this patient cohort including gastrostomy tube (G-tube) reliance, swallowing quality of life, and variables that contribute to improved swallowing outcomes. Retrospective chart review. A retrospective chart review of 18 consecutive patients treated with rendezvous procedures between April 2007 and May 2015 was carried out. Data were collected from chart review and follow-up telephone calls including demographics, surgical/postoperative course details, and Eating Assessment Tool (EAT-10) (swallowing quality of life) scores. The completion rate of the procedure was 83% (15 completed/3 procedures aborted). Average follow-up was 22 months. Thirteen of 15 (86.7%) achieved an oral diet, and 7/15 (46.7%) had their G-tube removed. G-tube-independent (GTI) patients had an average stricture length of 2.33 cm and an average distance from the incisors of 17.4 cm compared to G-tube dependent-(GTD) patients who had an average stricture length of 2.63 cm and 14.6 cm mean distance from the incisors (P = .66 and .0343, respectively). Final EAT-10 scores averaged 20.1 in GTI patients and 33.8 in GTD patients (P = .022). Stricture/incisor distance and EAT-10 scores demonstrated a moderate to strong negative correlation (r = -0.67). Following the endoscopic rendezvous procedure, swallowing outcomes and G-tube status is related to the distance of the stricture from the incisors. 2b Laryngoscope, 127:1388-1391, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

    Seasonally occurring populations of barn swallows nest near the Test Reactor Area (TRA) radioactive leaching ponds on the Idaho National Engineering Laboratory (INEL) Site. These birds utilize leaching pond arthropods and are therefore capable of accumulating radioactive materials and exporting them from the INEL Site during migration. The breeding biology is discussed for these swallows and a control group located 100 km away. Total nestling mortality for the controls and a 1977 TRA population was found to be statistically identical. Over 20 fission and activation products have been detected in immature and adult TRA birds. Mean concentrations of detectable radionuclides were used to calculate internal dose rates, and results showed that Na-24 contributed about 72% of the total average of 21.9 mrad/d for adult birds. Concentration factors were also calculated for predominant radionuclides in swallows relative to filtered pond water. Data from LiF dosimeters in swallow nests constructed with contaminated mud indicated average dose rates were 84 mrad/d for eggs and 220 mrad/d for nestlings. Growth curves were constructed for the immature TRA birds and controls. The first clutch of TRA swallows was found to have a significantly lower mean growth rate constant than the first clutch of controls. The statistical difference in growth rate between the control and TRA first clutch populations may have resulted from differences in climate, nesting site habitat, or available food sources, and cannot be solely attributed to radiation exposure as a causative factor. Growth rate parameters for TRA birds were within the range of values reported in the literature

    We conducted a cross-sectional study to assess vocal and swallowing functions after horizontal glottectomy. Our study population was made up of 22 men aged 45 to 72 years (mean: 58.3) who underwent horizontal glottectomy and completed at least 1 year of follow-up. To compare postoperative results, 20 similarly aged men were included as a control group; all glottectomy patients and all controls were smokers. We used three methods-acoustic and aerodynamic voice analyses, the GRBAS (grade, roughness, breathiness, asthenicity, and strain) scale, and the voice handicap index-30 (VHI-30)-to assess vocal function objectively, perceptually, and subjectively, respectively. We also assessed swallowing function objectively by fiberoptic endoscopic evaluation of swallowing (FEES) and subjectively with the M.D. Anderson dysphagia inventory (MDADI). The 22 patients were also subcategorized into three groups according to the extent of their arytenoid cartilage resection, and their outcomes were compared. Acoustic and aerodynamic analyses showed that the mean maximum phonation time was significantly shorter and the fundamental frequency was significantly lower in the glottectomy group than in the controls (p = 0.001 for both), and that the mean jitter and shimmer values and the mean harmonics-to-noise ratio were all significantly higher (p = 0.001 for all); there were no significant differences among the three arytenoid subgroups. Self-assessments revealed that there were no statistically significant differences among the three subgroups in GRBAS scale scores except for the breathiness score (p = 0.045), which was lower in the arytenoid preservation subgroup than in the total resection subgroup; there were no statistically significant differences among the three subgroups in VHI-30 scores. Finally, swallow testing found no statistically significant differences in FEES scores or MDADI scores. We conclude that horizontal glottectomy caused a deterioration in vocal function, but

    The purpose of this study was to investigate the somatotropic distribution and lateralization of motor and sensory cortical activity during swallowing in healthy adult human subjects using functional MR imaging. Nine healthy right-handed adult volunteers (6 men, 3 women; ages 22-38) were examined. Their cortical activities were evoked by having them swallow, five times, a small bolus of water (3 ml) supplied through a plastic catheter. As a positive control, the subjects performed five repetitions of right-handed grasping tasks. Blood oxygenation level-dependent images were obtained using a 1.5 Tesla MR system (Magnetom Vision, Siemens Germany; repetition time/echo time (TR/TE)=0.96/0.66, flip angle (FA)=90 deg). T1 weighted anatomical images were obtained for the same slices in each subject. Cerebral activity was observed most notably in the primary motor cortex and primary somatosensory cortex, followed by the premotor cortex, anterior cingulate cortex, frontal operculum, and insula. The hand-grasping task activated relatively superior parts of the primary motor and somatosensory cortices. The swallowing task, on the other hand, activated the inferior parts of the pre- and postcentral gyri. The hand-grasping activation of motor and sensory cortices was localized absolutely on the contralateral side, whereas swallowing activated the motor cortex either bilaterally or unilaterally. Swallowing activated the sensory cortex almost always bilaterally. This study suggested that fMRI could be used to identify the specific areas of cortical activation caused by various tasks, and to differentiate the locations of cortical activation between tasks.

    Three cases preselected by videofluorography were studied to evaluate whether electron beam tomography (EBT) permits more detailed dynamic imaging of swallowing disorders focusing on the mesonasopharyngeal segment, the hypopharynx and the upper esophageal sphincter (UES). Immediately after videofluorographic examination of the oropharyngeal deglutition, EBT is performed. The patient is in a supine position and while the patient swallows a 20 ml bolus of water or diluted iodine containing contrast agent, a sequence of 20 images per level is scanned. The levels, which are determined by using the scout view, are oriented parallel to the hard palate either at the level of the hard palate to image the mesonasopharyngel segment or just above the hyoid bone to focus on the hypopharynx or at the location of the USE. The scan technique is a single-slice cinemode with a slice thickness of 3 mm (exposure time 100 ms, interscan delay 16 ms, 130 kV, 620 mA). The following structural interactions that we have so far been unable to image can be clearly demonstrated with EBT: During normal swallowing, the mesonasopharyngeal segment is completely and symmetrically closed by the soft palate and Passavant's cushion; lateral hypopharyngeal pouches can be located more precisely; and disorders of the UES can be differentiated into functional or morphologically caused disorders (e.g., goiter or cervical osteophytes). Videofluorography and cinematography are still the gold standard in functional evaluation of swallowing disorders. However, EBT permits dynamic imaging of pharyngeal deglutition in a preselected transverse plane and can give useful additional information concerning functional anatomical changes in the pharynx during swallowing. Further clinical evaluation is needed. (orig.) [de

    Full Text Available Khalid A El Baba1, Sami T Azar21Department of Internal Medicine, Division of Endocrinology, Bahrain Specialist Hospital, Manama, Bahrain; 2Department of Internal Medicine, Division of Endocrinology, American University of Beirut-Medical Center, New York, NY, USAAbstract: Timely treatment of thyroid disease during pregnancy is important in preventing adverse maternal and fetal outcomes. Thyroid abnormalities are very often subclinical in nature and not easily recognized without specific screening programs. Even mild maternal thyroid hormone deficiency may lead to neurodevelopment complications in the fetus. The main diagnostic indicator of thyroid disease is the measurement of serum thyroid-stimulating hormone and free thyroxine levels. Availability of gestation-age-specific thyroid-stimulating hormone thresholds is an important aid in the accurate diagnosis and treatment of thyroid dysfunction. Pregnancy-specific free thyroxine thresholds not presently available are also required. Large-scale intervention trials are urgently needed to assess the efficacy of preconception or early pregnancy screening for thyroid disorders. Accurate interpretation of both antepartum and postpartum levels of thyroid hormones is important in preventing pregnancy-related complication secondary to thyroid dysfunction. This article sheds light on the best ways of management of thyroid dysfunction during pregnancy in order to prevent any possible maternal or fetal complication.Keywords: TSH, HCG, TBG

    Background Sacroiliac joint (SIJ) dysfunction is an important and underappreciated cause of chronic low back pain. Objective To prospectively and concurrently compare outcomes after surgical and non-surgical treatment for chronic SIJ dysfunction. Methods One hundred and forty-eight subjects with SIJ dysfunction were randomly assigned to minimally invasive SIJ fusion with triangular titanium implants (SIJF, n = 102) or non-surgical management (NSM, n = 46). SIJ pain (measured with a 100-point visual analog scale, VAS), disability (measured with Oswestry Disability Index, ODI) and quality of life scores were collected at baseline and at scheduled visits to 24 months. Crossover from non-surgical to surgical care was allowed after the 6-month study visit was complete. Improvements in continuous measures were compared using repeated measures analysis of variance. The proportions of subjects with clinical improvement (SIJ pain improvement ≥20 points, ODI ≥15 points) and substantial clinical benefit (SIJ pain improvement ≥25 points or SIJ pain rating ≤35, ODI ≥18.8 points) were compared. Results In the SIJF group, mean SIJ pain improved rapidly and was sustained (mean improvement of 55.4 points) at month 24. The 6-month mean change in the NSM group (12.2 points) was substantially smaller than that in the SIJF group (by 38.3 points, p<.0001 for superiority). By month 24, 83.1% and 82.0% received either clinical improvement or substantial clinical benefit in VAS SIJ pain score. Similarly, 68.2% and 65.9% had received clinical improvement or substantial clinical benefit in ODI score at month 24. In the NSM group, these proportions were <10% with non-surgical treatment only. Parallel changes were seen for EQ-5D and SF-36, with larger changes in the surgery group at 6 months compared to NSM. The rate of adverse events related to SIJF was low and only 3 subjects assigned to SIJF underwent revision surgery within the 24-month follow-up period. Conclusions In this Level

    We describe a novel device and method for real-time measurement of lingual-palatal pressure and automatic identification of the oral transfer phase of deglutition. Clinical measurement of the oral transport phase of swallowing is a complicated process requiring either placement of obstructive sensors or sitting within a fluoroscope or articulograph for recording. Existing detection algorithms distinguish oral events with EMG, sound, and pressure signals from the head and neck, but are imprecise and frequently result in false detection. We placed seven pressure sensors on a molded mouthpiece fitting over the upper teeth and hard palate and recorded pressure during a variety of swallow and non-swallow activities. Pressure measures and swallow times from 12 healthy and 7 Parkinson's subjects provided training data for a time-delay artificial neural network to categorize the recordings as swallow or non-swallow events. User-specific neural networks properly categorized 96 % of swallow and non-swallow events, while a generalized population-trained network was able to properly categorize 93 % of swallow and non-swallow events across all recordings. Lingual-palatal pressure signals are sufficient to selectively and specifically recognize the initiation of swallowing in healthy and dysphagic patients.

    The cervical auscultation refers to the observation and analysis of sounds or vibrations captured during swallowing using either a stethoscope or acoustic/vibratory detectors. Microphones and accelerometers have recently become two common sensors used in modern cervical auscultation methods. There are open questions about whether swallowing signals recorded by these two sensors provide unique or complementary information about swallowing function; or whether they present interchangeable information. The aim of this study is to present a broad comparison of swallowing signals recorded by a microphone and a tri-axial accelerometer from 72 patients (mean age 63.94 ± 12.58 years, 42 male, 30 female), who underwent videofluoroscopic examination. The participants swallowed one or more boluses of thickened liquids of different consistencies, including thin liquids, nectar-thick liquids, and pudding. A comfortable self-selected volume from a cup or a controlled volume by the examiner from a 5ml spoon was given to the participants. A comprehensive set of features was extracted in time, information-theoretic, and frequency domains from each of 881 swallows presented in this study. The swallowing sounds exhibited significantly higher frequency content and kurtosis values than the swallowing vibrations. In addition, the Lempel-Ziv complexity was lower for swallowing sounds than those for swallowing vibrations. To conclude, information provided by microphones and accelerometers about swallowing function are unique and these two transducers are not interchangeable. Consequently, the selection of transducer would be a vital step in future studies. PMID:28495001

    2017-01-01

    To investigate the impact of viscosity and peristaltic transport parameters on manometric pressure signatures, a reproducible swallowing process is required. Due to inter- and intra-subject variability from swallow to swallow, the human body does not represent an optimal mechanism for such an investigation. A smooth and continuous swallowing soft-robot has been developed to produce biomimetic swallowing trajectories, and is proposed to operate as a bench-top bolus rheometric investigation method. The method compares conventional viscometry and pressure signature findings from robotic swallowing experiments. The robotic aspect of experimentation involved 450 biomimetic swallows (10 repetitions of 45 unique experiments). The method examined swallowing transport in three dimensions: bolus formulation, peristaltic wavelength, and peristaltic velocity, each of which are known to contribute to safe and effective swallowing in vivo . It is found that the pressure gradients and magnitudes are commensurate with clinical reports on biological swallowing, on the order of 100 mmHg peak, however, the relationship between viscosity and pressure signatures is less clear. Bolus transport cannot be predicted as a function of bolus viscosity alone. Traditional viscometric data at 50 s −1 , as used in clinical practice, may not be a strong indicator of swallow effort, safety, or efficacy in vivo . (paper)

    Conclusion: Swedish anaesthesia personnel are concerned about the risk of postoperative cognitive side-effects but are more concerned about cardiovascular/pulmonary risks, pain, PONV and the rare event of awareness. Most respondents were not convinced about the use of depth-of-anaesthesia monitors. There is a need to improve knowledge around risk factors, prevention and management of postoperative cognitive side effects.

    This position document has been developed by the Dysphagia Working Group, a committee of members from the European Society for Swallowing Disorders and the European Union Geriatric Medicine Society, and invited experts. It consists of 12 sections that cover all aspects of clinical management of oropharyngeal dysphagia (OD) related to geriatric medicine and discusses prevalence, quality of life, and legal and ethical issues, as well as health economics and social burden. OD constitutes impaired or uncomfortable transit of food or liquids from the oral cavity to the esophagus, and it is included in the World Health Organization’s classification of diseases. It can cause severe complications such as malnutrition, dehydration, respiratory infections, aspiration pneumonia, and increased readmissions, institutionalization, and morbimortality. OD is a prevalent and serious problem among all phenotypes of older patients as oropharyngeal swallow response is impaired in older people and can cause aspiration. Despite its prevalence and severity, OD is still underdiagnosed and untreated in many medical centers. There are several validated clinical and instrumental methods (videofluoroscopy and fiberoptic endoscopic evaluation of swallowing) to diagnose OD, and treatment is mainly based on compensatory measures, although new treatments to stimulate the oropharyngeal swallow response are under research. OD matches the definition of a geriatric syndrome as it is highly prevalent among older people, is caused by multiple factors, is associated with several comorbidities and poor prognosis, and needs a multidimensional approach to be treated. OD should be given more importance and attention and thus be included in all standard screening protocols, treated, and regularly monitored to prevent its main complications. More research is needed to develop and standardize new treatments and management protocols for older patients with OD, which is a challenging mission for our societies

  17. Denture Mis-swallowing in the Sliding Esophageal Hiatal Hernia Mimics Esophageal Perforation

    2008-08-01

    Full Text Available Mis-swallowing of a foreign body in the esophagus coexisting with sliding hernia might be misdiagnosed as esophageal perforation with mediastinal abscess. We report an 89-year-old woman, bedridden for a long period in a nursing home after a previous cerebrovascular accident, who was sent to our emergency department in a state of sepsis because she had swallowed a radio-opaque partial denture. The retention of the denture as an esophageal foreign body was complicated with mediastinitis and bilateral pleural effusion. The inability of the patient to give a reliable clinical history delayed the diagnosis. This report highlights the difficulty in precisely locating a partial denture because of conflicting radiologic findings and the coexistence of esophageal sliding hernia, all of which led to a misdiagnosis of possible esophageal perforation. A right posterolateral thoracotomy with gastrostomy was performed to remove the lower esophageal foreign body after esophagoscopy failed. The surgical finding of a coincidental sliding esophageal hiatal hernia correlated well with the clinical presentation. Managing such a complicated esophageal foreign body in this elderly patient was challenging.

    Penile erection is a complex phenomenon that includes coordinated intraaction of the nervous, arterial, venous, and sinusoidal systems. A defect in any of these systems may result in erectile dysfunction. Erectile dysfunction is defined as the consistent inability to generate or maintain an erection of sufficient rigidity for sexual intercourse. Although the introduction of sildenafil citrate made the information from imaging studies less critical in the management of the patients with erectile dysfunction, still the imaging studies such as Doppler US, penile arteriography, and cavemosonetry/cavemosography remain the major modalities in the evaluation of erectile dysfunction.

    Huntington's disease (HD) is a degenerative genetic disorder with autosomal-dominant transmission. The triad of symptoms of this disease consists of psychiatric disorders, jerky movements, and dementia. Oropharyngeal dysphagia, which is more evident with disease progression, is also present. Few studies have addressed the swallowing characteristics using objective analysis in this population. The purpose of this research was to describe the swallowing endoscopic findings of the pharyngeal phase in HD. This is a cross-sectional study addressing a clinical case which included two individuals of the same family, male, 32 and 63 years old, designated as individual A and individual B, with progression of the disease for five and 13 years, respectively. Consistent liquid, nectar, and puree were offered during the evaluation. There was presence of posterior oral spillage in liquid and nectar, small amount of pharyngeal residues, and no laryngeal penetration or aspiration in the individuals with HD in this study.

    We tracked the development of innate immunity in nestling Tree Swallows (Tachycineta bicolor) and compared it to that of adults using blood drawn from nestlings during days 6, 12, and 18 of the ???20-day nestling period and from adults. Innate immunity was characterized using an in vitro assay of the ability of whole blood to kill Escherichia coli. The ability of whole blood to kill E. coli increased as nestlings matured. Neither this component of innate immunity nor right wing chord length on day18 were as developed as in adults indicating that development of the innate immune system and growth both continued after fledging. Narrow sense heritability analyses suggest that females with strong immune responses produced nestlings with strong immune responses. These data suggest nestling Tree Swallows allocated sufficient energy to support rapid growth to enable fledging by day 18, but that further development of innate immunity occurred post-fledging. ?? 2011 by the Wilson Ornithological Society.

    Contaminant exposure of tree swallows, Tachycineta bicolor, nesting in 27 Areas of Concern (AOCs) in the Great Lakes basin was assessed from 2010 to 2014 to assist managers and regulators in their assessments of Great Lakes AOCs. Contaminant concentrations in nestlings from AOCs were compared with those in nestlings from nearby non-AOC sites. Polychlorinated biphenyl (PCB) and polybrominated diphenyl ether concentrations in tree swallow nestling carcasses at 30% and 33% of AOCs, respectively, were below the mean concentration for non-AOCs. Polycyclic aromatic hydrocarbon (PAH) concentrations in nestling stomach contents and perfluorinated compound concentrations in nestling plasma at 67% and 64% of AOCs, respectively, were below the mean concentration for non-AOCs. Concentrations of PCBs in nestling carcasses were elevated at some AOCs but modest compared with highly PCB-contaminated sites where reproductive effects have been documented. Concentrations of PAHs in diet were sufficiently elevated at some AOCs to elicit a measurable physiological response. Among AOCs, concentrations of the perfluorinated compound perfluorooctane sulfonate in plasma were the highest on the River Raisin (MI, USA; geometric mean 330 ng/mL) but well below an estimated toxicity reference value (1700 ng/mL). Both PAH and PCB concentrations in nestling stomach contents and PCBs in carcasses were significantly correlated with concentrations in sediment previously reported, thereby reinforcing the utility of tree swallows to assess bioavailability of sediment contamination.

    Acoustic monitoring of swallow frequency has become important as the frequency of spontaneous swallowing can be an index for dysphagia and related complications. In addition, it can be employed as an objective quantification of ingestive behavior. Commonly, swallowing complications are manually detected using videofluoroscopy recordings, which require expensive equipment and exposure to radiation. In this study, a noninvasive automated technique is proposed that uses breath and swallowing recordings obtained via a microphone located over the laryngopharynx. Nonlinear diffusion filters were used in which a scale-space decomposition of recorded sound at different levels extract swallows from breath sounds and artifacts. This technique was compared to manual detection of swallows using acoustic signals on a sample of 34 subjects with Parkinson's disease. A speech language pathologist identified five subjects who showed aspiration during the videofluoroscopic swallowing study. The proposed automated method identified swallows with a sensitivity of 86.67 %, a specificity of 77.50 %, and an accuracy of 82.35 %. These results indicate the validity of automated acoustic recognition of swallowing as a fast and efficient approach to objectively estimate spontaneous swallow frequency.

    Swallowing evaluation of older individuals with coronary disease referred to heart surgery. To identify the characteristics of the swallowing function in older individuals referred to myocardial revascularization surgery (MR), using an evaluating protocol composed by a water test, cervical auscultation and pulse oximetry. The Assessment Protocol for Dysphagia Risk through a Combined Swallowing test and Vital Signs monitoring was used (PADTC)--measurements of HR and SpO2 (heart rate and oxygen saturation), water swallowing test with 1, 3, 5, 10, 15 e 20 ml, measurement of respiratory rate and cervical auscultation. The electronic stethoscope was used to analyze the number of swallows, response time and swallowing sound classification. In the Research Group (RG) older individuals with heart disease who were referred to MR were included. In the Control Group (CG) healthy older individuals were included. 38 older individuals were evaluated in the RG (mean age 68 years). In the CG, 30 older individuals were evaluated (mean age 70 years). There was a significant difference for the swallowing response time in older individuals with heart disease who presented HR below 60: swallowing response was shorter for 3 ml, 10 ml, 15 ml e 20 ml. HR was lower for individuals with heart disease. No significant difference was found between the groups for the other analyzed parameters. Older individuals with heart disease presented differences in the swallowing function when compared to healthy older individuals. Older individuals with heart disease presented alterations in the temporal coordination between breathing and swallowing, thus indicating risk for dysphagia.

    The key objective of mastication is to form a food bolus suitable for smooth swallowing. However, chewing is usually performed without a conscious effort. Poor bolus formation can cause pharyngeal residue and suffocation in elderly individuals with reduced swallowing function. Therefore, chewing with a conscious effort may help the bolus to more easily pass the pharynx. This study aimed to clarify the impact of mastication with a conscious effort on the feeding sequence. Subjects included 25 dentulous volunteers who were informed and provided written consent. Lateral videofluoroscopy was performed during the feeding of solid agar jelly under two conditions: chewing naturally in their usual manner (without volition) and chewing with a conscious effort (with volition). Temporal evaluation was performed for mastication, stage II transport (STII), swallow onset and oropharyngeal transit time. Moreover, bolus volume at swallow onset and subjective evaluation of swallowing easiness were measured. Volitional chewing with a conscious effort lengthened the duration of the chewing sequence before and after STII and delayed the swallow onset despite the fact that the bolus volume in the vallecula and hypopharynx (HYP) had significantly increased. Furthermore, with volition, the bolus transit time from swallow onset in the oral cavity, upper oropharynx and HYP was reduced, and subjective evaluation of swallowing easiness demonstrated significant improvement. These results suggest that volitional chewing with a conscious effort can alter bolus transport and swallowing, resulting in easier swallowing. © 2014 John Wiley & Sons Ltd.

    Surface electrical stimulation of the laryngeal region is used to improve swallowing in dysphagic patients. However, little is known about how electrical stimulation affects tongue movements and related functions. We investigated the effect of electrical stimulation on tongue pressure and hyoid movement, as well as suprahyoid and infrahyoid muscle activity, in 18 healthy young participants. Electrical stimulation (0.2-ms duration, 80 Hz, 80% of each participant's maximal tolerance) of the laryngeal region was applied. Each subject swallowed 5 ml of barium sulfate liquid 36 times at 10-s intervals. During the middle 2 min, electrical stimulation was delivered. Tongue pressure, electromyographic activity of the suprahyoid and infrahyoid muscles, and videofluorographic images were simultaneously recorded. Tongue pressure during stimulation was significantly lower than before or after stimulation and was significantly greater after stimulation than at baseline. Suprahyoid activity after stimulation was larger than at baseline, while infrahyoid muscle activity did not change. During stimulation, the position of the hyoid at rest was descended, the highest hyoid position was significantly inferior, and the vertical movement was greater than before or after stimulation. After stimulation, the positions of the hyoid at rest and at the maximum elevation were more superior than before stimulation. The deviation of the highest positions of the hyoid before and after stimulation corresponded to the differences in tongue pressures at those times. These results suggest that surface electrical stimulation applied to the laryngeal region during swallowing may facilitate subsequent hyoid movement and tongue pressure generation after stimulation. NEW & NOTEWORTHY Surface electrical stimulation applied to the laryngeal region during swallowing may facilitate subsequent hyoid movement and tongue pressure generation after stimulation. Tongue muscles may contribute to overshot recovery

    Objective: To offer some visual and valuable clinical bases for the pharynx disease diagnosis and treatment by comparing the influence of different scanning sequences on the image quality and scanning time, and studying the application to the dynamic swallowing MRI scanning. Methods: The dynamic swallowing scanning of pharyngeal was performed on 20 nasopharyngeal carcinoma patients without deglutition disorders through GE 3.0 MRI system with fast imaging employing steady state acquisition (FIESTA) and fast gradient recalled echo (Fast GRE) sequences, and combined with the array spatial sensitivity encoding technique (ASSET), which accelerating factors was 2.0 ph, and sixty dynamic images were acquired sequentially. The image quality was graded into three classes:excellent, favorable and poor,which were visually assessed by three senior MRI physician using double-blinded method. The quantitative data were analyzed statistically with the SPSS13.0 software. Results: Under the same parameters,the scanning time with FIESTA, FIESTA+ASSET, Fast GRE and Fast GREA+ASSET sequences were 54 s, 28 s, 49 s and 25 s respectively. The number of excellent images with the four sequences were 44, 52, 52 and 56 respectively. The scanning time was the shortest and the image quality was the best with Fast GRE+ASSET sequence. Conclusions: The dynamic imaging of swallowing in sagittal view was achieved with Fast GRE+ASSET sequence on GE 3.0T MRI system. It could present status of the pharynx well, and the soft tissue of swallowing was showed clearly in the dynamic images. These will provide visual and effective evidence for clinical diagnosis and treatment. (authors)

    Objective: To determine the feasibility of cine-MRI for non-invasive swallowing evaluation after surgery for lingual carcinoma with reconstruction using microvascular free flaps. Methods: Ten patients with stage IV carcinoma of the mobile tongue and/or tongue base treated by surgical resection and reconstruction with a free flap were evaluated after an average of 4.3 years (range: 1.5-11 years), using cine-MRI in 'single-shot fast spin echo' (SSFSE) mode. Fiberoptic laryngoscopy of swallowing was performed before MRI to detect aspiration. The tolerance and ability to complete the exam were noted. The mobilities of the oral and pharyngeal structures visualized were evaluated as normal, reduced or increased. Results: Cine-MRI was well tolerated in all cases; 'dry' swallow was performed for the 2 patients with clinical aspiration. Tongue base-pharyngeal wall contact was observed in 5 cases. An increased anterior tongue recoil, increased mandibular recoil, increased posterior oropharyngeal wall advancement and an increased laryngeal elevation were observed in 4 cases. One case of a passive 'slide' mechanism was observed. Conclusions: Cine-MRI is a safe, non-invasive technique for the evaluation of the mobility of oral and oropharyngeal structures after free-flap reconstruction of the tongue. For selected cases, it may be complementary to clinical examination for evaluation of dysphagia after surgery and free-flap reconstruction. Further technical advances will be necessary before cine-MRI can replace videofluoroscopy, however.

    Full Text Available CONTEXT: It has been demonstrated that the ageing process affects esophageal motility. OBJECTIVES: To evaluate the effect of the age on the proximal esophageal response to wet swallows. METHOD: We measured the proximal esophageal response to swallows of a 5 mL bolus of water in 69 healthy volunteers, 20 of them aged 18-30 years (group I, 27 aged 31-50 years (group II, and 22 aged 51-74 years (group III. We used the manometric method with continuous perfusion. The proximal esophageal contractions were recorded 5 cm from a pharyngeal recording site located 1 cm above the upper esophageal sphincter. The time between the onset of the pharyngeal and of the proximal esophageal recording (pharyngeal-esophageal time and the amplitude, duration and area under the curve of the proximal esophageal contraction were measured. RESULTS: The pharyngeal-esophageal time was shorter in group I subjects than in group II and III subjects (P<0.05. The duration of proximal esophageal contractions was longer in group I than in groups II and III (P<0.001. There was no differences between groups in the amplitude or area under the curve of contractions. There were no differences between groups II and III for any of the measurements. CONCLUSION: We conclude that the age may affects the response of the proximal esophagus to wet swallows.

    2013-03-01

    Monitoring Ingestive Behavior (MIB) of individuals is of special importance to identify and treat eating patterns associated with obesity and eating disorders. Current methods for MIB require subjects reporting every meal consumed, which is burdensome and tend to increase the reporting bias over time. This study presents an evaluation of the burden imposed by two wearable sensors for MIB during unrestricted food intake: a strain sensor to detect chewing events and a throat microphone to detect swallowing sounds. A total of 30 healthy subjects with various levels of adiposity participated in experiments involving the consumption of four meals in four different visits. A questionnaire was handled to subjects at the end of the last visit to evaluate the sensors burden in terms of the comfort levels experienced. Results showed that sensors presented high comfort levels as subjects indicated that the way they ate their meal was not considerably affected by the presence of the sensors. A statistical analysis showed that chewing sensor presented significantly higher comfort levels than the swallowing sensor. The outcomes of this study confirmed the suitability of the chewing and swallowing sensors for MIB and highlighted important aspects of comfort that should be addressed to obtain acceptable and less burdensome wearable sensors for MIB.

    There is a paucity of research that investigates therapeutic interventions of patients with concurrent head and neck lymphedema and temporomandibular dysfunction (TMD). The purpose of this case report is to describe the management and outcomes of a patient with head and neck lymphedema and TMD using a multimodal physical therapy approach. A 74-year-old male with a past medical history of head and neck lymphedema and TMD was referred to physical therapy with chief complaints of inability to open his mouth in order to eat solid food, increased neck lymphedema, temporomadibular joint pain, and inability to speak for prolonged periods of time. The patient was treated for three visits over 4 weeks. Treatment included complete decongestive therapy (CDT), manual therapy, therapeutic exercise, and a home exercise program. Upon discharge, the patient had improved mandibular depression, decreased head and neck lymphedema, improved deep neck flexor endurance, decreased pain, and improved function on the Patient Specific Functional Scale (PSFS). Utilization of a multimodal physical therapy approach to treat a patient with a complex presentation yielded positive outcomes. Further research on outcomes and treatment approaches in patients with TMD and head and neck lymphedema is warranted.

    Sacroiliac joint dysfunction (SIJD) is a condition affecting 15-30% of patients with low back pain seen in outpatient clinics. Currently there is no well-defined standard of care. The purpose of this case report is to discuss the multidisciplinary management between an athletic trainer and an optometrist for an athlete with bilateral SIJ dysfunction and a visual midline shift syndrome. A 21-year-old collegiate baseball player reported to the athletic training room, presenting with low back pain of three day duration, with tenderness over both posterior superior iliac spines (PSIS) (left > right). His pain at its worse was a 7/10 on the Numeric Pain Scale (NPS). The pain increased to the point that it limited his activities of daily living (ADLs) including getting dressed, putting on his shoes, sleeping, and getting in and out of a car. The athlete was initially treated using traditional muscle energy techniques (MET) based intervention to correct SIJD, and lumbar stabilization exercises directed by a licensed athletic trainer, as well as manipulation by a chiropractor. Three weeks of treatment did not prove to be beneficial with only a minimal (1 point on the NPRS) decrease in pain. The athlete was then referred to the head athletic trainer for consultation who prescribed orthotics, for bilateral rear-foot valgus, and Postural Restoration (PR) therapeutic exercises. After two weeks of orthotic use and PR exercises the athlete's pain decreased one additional point on the NPRS. Due to lack of progress, an optometrist was then consulted. The neuro-optometrist prescribed 2 diopter base-down prisms to be worn two hours a day, for four weeks. After four weeks of prisms and new exercises, the athlete was asymptomatic and returned to full pain-free baseball participation without further complications. The Oswestry Disability Index Questionnaire (ODI) was 48% at initial (severe disability), 40% at five weeks and 0% at discharge. The Numeric Pain Scale (NPS) score went from

    Malnutrition and cognitive impairment lead to declines in activities of daily living (ADL). Nutritional status and cognitive ability have been shown to correlate with oral health status and swallowing function. However, the complex relationship among the factors that affect decline in ADL is not understood. We examined direct and indirect relationships among oral health status, swallowing function, nutritional status, cognitive ability, and ADL in Japanese elderly people living at home and receiving home care services because of physical disabilities. Participants were 286 subjects aged 60 years and older (mean age, 84.5±7.9 years) living at home and receiving home care services. Oral health status (the number of teeth and wearing dentures) was assessed, and swallowing function was examined using cervical auscultation. Additionally, ADL, cognitive ability, and nutritional status were assessed using the Barthel Index, the Clinical Dementia Rating Scale, and the Mini Nutritional Assessment-Short Form, respectively. Path analysis was used to test pathways from these factors to ADL. The mean number of teeth present in the participants was 8.6±9.9 (edentates, 40.6%). Dysphagia, malnutrition, and severe cognitive impairment were found in 31.1%, 14.0%, and 21.3% of the participants, respectively. Path analysis indicated that poor oral health status and cognitive impairment had a direct effect on denture wearing, and the consequent dysphagia, in addition to cognitive impairment, was positively associated with malnutrition. Malnutrition as well as dysphagia and cognitive impairment directly limited ADL. A lower number of teeth are positively related to swallowing dysfunction, whereas denture wearing contributes to recovery of swallowing function. Dysphagia, cognitive impairment, and malnutrition directly and indirectly decreased ADL in elderly people living at home and receiving home nursing care. The findings suggest that preventing tooth loss and encouraging denture

    Automated detection of swallowing sounds in swallowing and breath sound recordings is of importance for monitoring purposes in which the recording durations are long. This paper presents a novel method for swallowing sound detection using hidden Markov modeling of recurrence plot features. Tracheal sound recordings of 15 healthy and nine dysphagic subjects were studied. The multidimensional state space trajectory of each signal was reconstructed using the Taken method of delays. The sequences of three recurrence plot features of the reconstructed trajectories (which have shown discriminating capability between swallowing and breath sounds) were modeled by three hidden Markov models. The Viterbi algorithm was used for swallowing sound detection. The results were validated manually by inspection of the simultaneously recorded airflow signal and spectrogram of the sounds, and also by auditory means. The experimental results suggested that the performance of the proposed method using hidden Markov modeling of recurrence plot features was superior to the previous swallowing sound detection methods.

    This article reviews the history of the barium swallow from its early role in radiology to its current status as an important diagnostic test in modern radiology practice. Though a variety of diagnostic procedures can be performed to evaluate patients with dysphagia or other pharyngeal or esophageal symptoms, the barium study has evolved into a readily available, non-invasive, and cost-effective technique that can facilitate the selection of additional diagnostic tests and guide decisions about medical, endoscopic, or surgical management. This article focuses on the evolution of fluoroscopic equipment, radiography, and contrast media for evaluating the pharynx and esophagus, the importance of understanding pharyngoesophageal relationships, and major advances that have occurred in the radiologic diagnosis of select esophageal diseases, including gastroesophageal reflux disease, infectious esophagitis, eosinophilic esophagitis, esophageal carcinoma, and esophageal motility disorders.

    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. In a cohort of 63 acute stroke cases, swallow frequency rates (swallows per minute [SPM]) were compared with stroke and swallow severity indices, age, time from stroke to assessment, and consciousness level. Mean differences in SPM were compared between patients with versus without clinically significant dysphagia. Receiver operating characteristic curve analysis was used to identify the optimal threshold in SPM, which was compared with a validated clinical dysphagia examination for identification of dysphagia cases. Time series analysis was used to identify the minimally adequate time period to complete spontaneous swallow frequency analysis. 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. Receiver operating characteristic curve analysis yielded a threshold of SPM≤0.40 that 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. Spontaneous swallowing frequency presents high potential to screen for dysphagia in acute stroke without the need for trained, available personnel.

    Dysphagia is the main cause of aspiration pneumonia and death in Parkinson disease (PD) with no established restorative behavioral treatment to date. Reduced swallow safety may be related to decreased elevation and excursion of the hyolaryngeal complex. Increased submental muscle force generation has been associated with expiratory muscle strength training (EMST) and subsequent increases in hyolaryngeal complex movement provide a strong rationale for its use as a dysphagia treatment. The current study's objective was to test the treatment outcome of a 4-week device-driven EMST program on swallow safety and define the physiologic mechanisms through measures of swallow timing and hyoid displacement. This was a randomized, blinded, sham-controlled EMST trial performed at an academic center. Sixty participants with PD completed EMST, 4 weeks, 5 days per week, for 20 minutes per day, using a calibrated or sham, handheld device. Measures of swallow function including judgments of swallow safety (penetration-aspiration [PA] scale scores), swallow timing, and hyoid movement were made from videofluoroscopic images. No pretreatment group differences existed. The active treatment (EMST) group demonstrated improved swallow safety compared to the sham group as evidenced by improved PA scores. The EMST group demonstrated improvement of hyolaryngeal function during swallowing, findings not evident for the sham group. EMST may be a restorative treatment for dysphagia in those with PD. The mechanism may be explained by improved hyolaryngeal complex movement. This intervention study provides Class I evidence that swallow safety as defined by PA score improved post EMST.

    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 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.

    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.

    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.

    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 mechanics by motor neuron predominance (D = 5.03, p 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.

    Dysphagia is caused not only by neurological and/or structural damage but also by medication. We hypothesized memantine, dextromethorphan, diazepam, and baclofen, all commonly used drugs with central sites of action, may regulate swallowing function. Swallows were evoked by upper airway (UA)/pharyngeal distension, punctate mechanical stimulation using a von Frey filament, capsaicin or distilled water (DW) applied topically to the vocal folds, and electrical stimulation of a superior laryngeal nerve (SLN) in anesthetized rats and were documented by recording electromyographic activation of the suprahyoid and thyrohyoid muscles and by visualizing laryngeal elevation. The effects of intraperitoneal or topical administration of each drug on swallowing function were studied. Systemic administration of diazepam and baclofen, but not memantine or dextromethorphan, inhibited swallowing evoked by mechanical, chemical, and electrical stimulation. Both benzodiazepines and GABA A receptor antagonists diminished the inhibitory effects of diazepam, whereas a GABA B receptor antagonist diminished the effects of baclofen. Topically applied diazepam or baclofen had no effect on swallowing. These data indicate that diazepam and baclofen act centrally to inhibit swallowing in anesthetized rats. NEW & NOTEWORTHY Systemic administration of diazepam and baclofen, but not memantine or dextromethorphan, inhibited swallowing evoked by mechanical, chemical, and electrical stimulation.

    Feeding and swallowing problems in infants and children have a great impact on health and wellbeing. The aim of this study was to provide an overview of recognized feeding and swallowing problems in different groups of children with neuromuscular diseases, based on relevant literature and expert opinion, and to propose recommendations for the assessment and treatment of these problems. Almost all pediatric neuromuscular diseases are accompanied by feeding and swallowing problems during the different phases of deglutition, problems that give rise to a wide variety of signs and symptoms, which emphasizes the importance of a comprehensive feeding and swallowing assessment by a speech and language therapist.

    Airway protections is the prevention and/or removal of material by behaviors such as cough and swallow. We hypothesized these behaviors are coordinated to respond to aspiration. Anesthetized animals were challenged with simulated aspiration that induced both coughing and swallowing. Electromyograms of upper airway and respiratory muscles together with esophageal pressure were recorded to identify and evaluate cough and swallow. During simulated aspiration, both cough and swallow intensity increased and swallow duration decreased consistent with rapid pharyngeal clearance. Phase restriction between cough and swallow was observed; swallow was restricted to the E2 phase of cough. These results support three main conclusions: 1) the cough and swallow pattern generators are tightly coordinated so as to generate a protective meta-behavior; 2) the trachea provides feedback on swallow quality, informing the brainstem about aspiration incidences; and 3) the larynx and upper esophageal sphincter act as two separate valves controlling the direction of positive and negative pressures from the upper airway into the thorax.

    To verify the frequency of swallowing complaints in patients with benign nonsurgical thyroid disease and compare the self-perception of swallowing disorder intensity between different types of thyroid disease. The study sample comprised 39 women aged 19-58 years (38.54 ± 10.74) with hypothyroidism (n=22; 56.4%) or thyroid nodules (n=17; 43.6%). Presence and type of swallowing complaint and self-perception of swallowing disorder intensity were investigated by means of self-ratings recorded on a 100-millimeter visual analog scale. The data were analyzed by descriptive measures and the Mann-Whitney nonparametric test was used to compare the self-perception of swallowing disorder intensity between both clinical diagnoses of thyroid disease. The level of 5% was adopted for statistical significance. Twenty-six (66.7%) individuals reported the following swallowing complaints: pharyngolaryngeal stasis sensation (37.15%), chocking (34.29%), and odynophagia (28.57%). The mean value of self-perception of swallowing disorder intensity by the visual analog scale was 59.35 (± 27.38) millimeters. No difference in self-perception was reported between the clinical diagnoses of thyroid disease. In this sample, swallowing complaint was frequently observed in patients with benign nonsurgical thyroid disease. Moderate self-perception of swallowing disorder intensity was reported regardless of the clinical diagnosis of thyroid disease.

    Cervical auscultation with high resolution sensors is currently under consideration as a method of automatically screening for specific swallowing abnormalities. To be clinically useful without human involvement, any devices based on cervical auscultation should be able to detect specified swallowing events in an automatic manner. In this paper, we comparatively analyze the density-based spatial clustering of applications with noise algorithm (DBSCAN), a k-means based algorithm, and an algorithm based on quadratic variation as methods of differentiating periods of swallowing activity from periods of time without swallows. These algorithms utilized swallowing vibration data exclusively and compared the results to a gold standard measure of swallowing duration. Data was collected from 23 subjects that were actively suffering from swallowing difficulties. Comparing the performance of the DBSCAN algorithm with a proven segmentation algorithm that utilizes k-means clustering demonstrated that the DBSCAN algorithm had a higher sensitivity and correctly segmented more swallows. Comparing its performance with a threshold-based algorithm that utilized the quadratic variation of the signal showed that the DBSCAN algorithm offered no direct increase in performance. However, it offered several other benefits including a faster run time and more consistent performance between patients. All algorithms showed noticeable differentiation from the endpoints provided by a videofluoroscopy examination as well as reduced sensitivity. In summary, we showed that the DBSCAN algorithm is a viable method for detecting the occurrence of a swallowing event using cervical auscultation signals, but significant work must be done to improve its performance before it can be implemented in an unsupervised manner.

    Miniature Schnauzers maintained in a colony for 9 years were used to study the inheritance of esophageal dysfunction (canine achalasia, megaesophagus). All dogs were evaluated radiographically, using a barium swallow contrast technique which clearly distinguished normal and affected pups. At 4 to 6 months of age, all affected dogs had recovered clinically except one, and radiographic evidence of dysfunction was markedly diminished. None of the affected dogs required a special feeding regimen. Analysis of breeding pairs revealed a ratio of 9 affected/11 normal dogs when an affected male was mated with a normal female, and a 13/3 ratio was observed when two affected dogs were mated. These ratios were compatible with a simple autosomal dominant or a 60% penetrance autosomal-recessive mode of inheritance. Outbreeding to an affected Miniature Schnauzer/Poodle crossbred dog resulted in only two of 30 affected pups, indicating a polygenic mode of inheritance in outbred populations.

    From a very simplistic viewpoint, the human digestive system can be regarded as a long tube (with dramatic variations in diameter, cross-section, wall properties, pumping mechanisms, regulating valves and in-line sensors). We single out a few fluid mechanical phenomena along the trajectory of a food bolus from the mouth to the small intestine and discuss how they influence sensorial perception, safe transport, and nutrient absorption from a bolus. The focus is on lubrication flows between the tongue and palate, the oropharyngeal stage of swallowing and effects of flow on absorption in the small intestine. Specific challenges and opportunities in this research area are highlighted.

    Objective: To verify the clinical outcomes of applying water swallowing to MR esophagography. Methods: Thirty patients confirmed postoperatively or histopathologically with thoracic esophageal carcinoma by endoscopic biopsy and 10 healthy volunteers with normal esophagus underwent respectively conventional magnetic resonance imaging (MRI) detection and water swallowing MR esophagography. Of those patients, 4 underwent second examination after radiotherapy. Assessment on imaging effects of MR esophagography was performed. Assessment on definition on MR esophagography of the tumor in both upper and lower ends, specific localization, tumor size finally measured, coincidence with the gross pathologic types and tumor staging were respectively performed by comparison with conventional MRI. Additionally, we evaluated the outcomes of radiotherapy by comparing the previous MR esophagography with the second one with interventional technique. Results: Of the total 44 images of MR esophagography, 97.7% (43/44) were in high resolution by sagittal view and 81.8% (36/44) by cross-section. 93.3% (56/60) of the MR esophagography were clearly defined with the neoplastic lesion ends in the 30 patients with thoracic esophageal carcinoma, compared with 11.7% (7/60) by conventional MRI. The results were totally different in statistics (P < 0.005). Preoperative conventional MRI detection of the 22 cases in 25 undergone radical resection suggested vague diameter of the primary tumor and impossibly identified it at middle-lower thoracic esophagus in 5, and even failed to confirm gross pathologic types in 19 cases. Yet, MR esophagography with water swallowing represented accurate tumor length (graded as excellent) in 88% (22/25), localization in 100% (25/25), exact gross pathologic types in 88% (22/25), and accuracy for tumor staging in 80.8% (21/26) compared to 92.3% (24/26) by conventional MRI. Therapeutic effects achieved in 4 patients with radiotherapy. Conclusions: MR esophagography

    This study explores whether changes in voice- and swallow-related QoL are associated with progression of idiopathic Parkinson's disease (IPD). Furthermore, it examines the relationship between patients' perception of both voice and swallowing disorders in IPD. Prospective clinical study, quality of life (QoL). One-hundred mentally competent IPD patients with voice and swallowing complaints were asked to answer four QoL questionnaires (Voice Handicap Index, MD Anderson Dysphagia Inventory, Visual Analog Scale [VAS] voice, and Dysphagia Severity Scale [DSS]). Differences in means for the QoL questionnaires and their subscales within Hoehn and Yahr stage groups were calculated using one-way analysis of variance. The relationship between voice- and swallow-related QoL questionnaires was determined with the Spearman correlation coefficient. Scores on both voice and swallow questionnaires suggest an overall decrease in QoL with progression of IPD. A plateau in QoL for VAS voice and the DSS was seen in the early Hoehn and Yahr stages. Finally, scores on voice-related QoL questionnaires were significantly correlated with swallow-related QoL outcomes. Voice- and swallow-related QoL decreases with progression of IPD. A significant association was found between voice- and swallow-related QoL questionnaires. Healthcare professionals can benefit from voice- and swallow-related QoL questionnaires in a multidimensional voice- or swallow-assessment protocol. The patient's perception of his/her voice and swallowing disorders and its impact on QoL in IPD should not be disregarded. 2b. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    Eating and drinking are enjoyable activities that positively impact on an individual's quality of life. The ability to swallow food and fluid is integral to the process of eating. Swallowing occupies a dual role being both part of the enjoyment of eating and being a critically important utilitarian activity to enable adequate nutrition and hydration. Any impairment to the process of swallowing can negatively affect a person's perception of their quality of life. The process of swallowing is highly complex and involves muscles in the mouth, pharynx, larynx, and esophagus. The oropharynx is the anatomical region encompassing the oral cavity and the pharynx. Food must be masticated, formed into a bolus and transported to the pharynx by the tongue whereas fluids are usually held within the mouth before being transported ab-orally. The bolus must then be transported through the pharynx to the esophagus without any matter entering the larynx. The muscles needed for all these steps are coordinated by swallowing centers within the brainstem which are supplied with sensory information by afferent nerve fibers from several cranial nerves. The swallowing centers also receive modulatory input from higher centers within the brain. Hence, a swallow has both voluntary and involuntary physiologic components and the term dysphagia is given to difficult swallowing while oropharyngeal dysphagia is difficult swallowing due to pathology within the oropharynx. Problems affecting any point along the complex swallowing pathway can result in dysphagia. This review focuses on the anatomy and physiology behind normal and abnormal oropharyngeal swallowing. It also details the common diseases and pathology causing oropharyngeal dysphagia. © 2017 John Wiley & Sons Ltd.

    In the evaluation of the dysphagic patient, radiology is crucial as a technique for monitoring morphology and function. In particular, high-speed cineradiography can reveal a variety of pharyngeal dysfunctions. However, in the literature and in practice the difference between normal and abnormal function is not always clear. This monography is based on high-speed cineradiographies of swallowing in 75 non-dysphagic volunteers and in 189 dysphagic patients. The purpose was to study whether differences in bolus volumes, patient position, age and gender had any effects on the following parameters: the speed of the peristaltic wave and apex of the liquid barium bolus, the length of movement and the movement pattern of the hyoid bone and larynx, and epiglottic function. The study disclosed that the speed of the bolus, the anterior-superior movement and net movement of the hyoid bone increased significantly with larger bolus volumes. The position of the individual in relation to gravity significantly influenced the speed of peristalsis. In most of the measured parameters there were no differences between non-dysphagic and dysphagic individuals expect for differences in the intrapersonal variations and in the anterior-superior movement of the hyoid bone. In patients with pharyngeal dysfunction the initial stage of the elevation of the larynx was significantly lower than in patients without dysfunction. The approximation of the thyroid cartilage to the hyoid bone was significantly greater in individuals with normal epiglottic function than in those with epiglottic dysmobility. It is suggested that abnormal speed of peristalsis may be a mild form of dysfunction. Measurements of the aforementioned speed and movements can be done if bolus volume, age and position of the patient, film speed and magnifications factors are known. Hypotheses concerning epiglottic function and central control of swallowing are proposed. (au)

    Taste dysfunction is a significant but underestimated issue for patients with cancer. Impaired taste results in changes in diet and appetite, early satiety, and impaired social interactions. Nurses can play a key role in educating patients and families on the pathophysiology of taste dysfunction by suggesting interventions to treat the consequences of taste dysfunction, when available, and offering psychosocial support as patients cope with this often devastating consequence of treatment. Taste recognition helps humans identify the nutritional quality of food and signals the digestive tract to begin secreting enzymes. Spoiled or tainted foods typically are recognized by their bad taste. Along with the other sensory systems, taste is crucial for helping patients treated for cancer feel normal. This article will review the anatomy and physiology of taste; define the different types of taste dysfunction, including the underlying pathophysiologic basis related to cancer treatment; and discuss potential nursing interventions to manage the consequences of taste dysfunction.

  4. Sexual dysfunctions after prostate cancer radiation therapy

    Sexual dysfunctions are a quality of life main concern following prostate cancer treatment. After both radiotherapy and brachytherapy, sexual function declines progressively, the onset of occurrence of erectile dysfunction being 12-18 months after both treatments. The pathophysiological pathways by which radiotherapy and brachytherapy cause erectile dysfunction are multi-factorial, as patient co-morbidities, arterial damage, exposure of neurovascular bundle to high levels of radiation, and radiation dose received by the corpora cavernosa at the crurae of the penis may be important in the aetiology of erectile dysfunction. Diagnosis and treatment of postradiation sexual dysfunctions must integrate pre-therapeutic evaluation and information to provide to the patient and his partner a multidisciplinary sexual medicine management.

    Globus sensation is common, but its pathogenesis is not yet clear. Our purpose was to investigate subjective perception of swallowing and esophageal motility by combined multichannel intraluminal impedance and manometry (MII-EM) for patients with globus sensation. Combined MII-EM was performed for 25 globus patients and 15 healthy controls. Swallows were abnormal if hypocontractivity or simultaneous contractions occurred. Esophageal bolus transit was incomplete if bolus exit was not found at one or more of all measurement sites. Perception of each swallow was assessed by use of a standardized scoring system, and was enhanced if the score was >1. Few globus patients reported enhanced perception during viscous or solid swallows. Incomplete bolus transit and enhanced perception occurred similarly between viscous and solid boluses. Agreement between enhanced perception and proximal bolus clearance was greater during solid swallows (κ = 0.45, 95 % CI: 0.32-0.58) than during viscous swallows (κ = 0.13, 95 % CI: 0-0.25) (P perception and total bolus clearance was greater during solid swallows (κ = 0.46, 95 % CI: 0.34-0.58) than during viscous swallows (κ = 0.11, 95 % CI: 0-0.22) (P perception is uncommon in patients with globus sensation, although there is a significant association between enhanced esophageal perception and solid bolus clearance. Application of a solid bolus may help better delineation of the interrelationship between the subjective perception of bolus passage and the objective measurement of bolus clearance.

    2008-08-01

    Fiberoptic endoscopic evaluation of swallowing (FEES) is now a first choice method for studying swallowing disorders on account of the various advantages it offers: easy to use, very well tolerated, allows bedside examination and is economic. Nevertheless, this diagnostic procedure is not without risks, the most probable consequences of which include discomfort, gagging and/or vomiting, vasovagal syncope, epistaxis, mucosal perforation, adverse reactions to topical anaesthetics and laryngospasm. The risks involved with FEES stress the importance of informing the patient of these; this is an important aspect in medicine that necessarily and immediately implies receiving the patient's so-called "informed consent". Informed consent should be obtained not only by means of specific printed forms but also after the patient has had an interview with the physician who will be performing the procedure and who will offer information according to the personal clinical, psychological, cultural and linguistic situation of the patient and in keeping with the type of procedure proposed. In the case of FEES, as with other invasive or non-invasive diagnostic procedures, therefore, routine written and signed consent, together with a patient/physician interview should fulfil what is known as "complete information". In this report, a specific form for informed consent to FEES procedures, is proposed.

  15. A Mathematical Model for Swallowing of Concentrated Fluids in Oesophagus

    Directory of Open Access Journals (Sweden)

    S. K. Pandey

    2011-01-01

    Full Text Available This model investigates particularly the impact of an integral and a non-integral number of waves on the swallowing of food stuff such as jelly, tomato puree, soup, concentrated fruits juices and honey transported peristaltically through the oesophagus. The fluid is considered as a Casson fluid. Emphasis is on the study of the dependence of local pressure distribution on space and time. Mechanical efficiency, reflux limit and trapping are also discussed. The effect of Casson fluid vis-à-vis Newtonian fluid is investigated analytically and numerically too. The result is physically interpreted as that the oesophagus makes more efforts to swallow fluids with higher concentration. It is observed that the pressure is uniformly distributed when an integral number of waves is there in the oesophagus; but it is non-uniform when a non-integral number of waves is present therein. It is further observed that as the plug flow region widens, the pressure difference increases, which indicates that the averaged flow rate will reduce for a Casson fluid. It is also concluded that Casson fluids are more prone to reflux.

    2013-01-01

    Objective: Intrarater and interrater reliability is crucial to the quality of diagnostic and therapy-effect studies. This paper reports on a systematic review of studies on intrarater and interrater reliability for measurements in videofluoroscopy of swallowing. The aim of this review was to summarize and qualitatively analyze published studies on that topic. Materials and methods: Those published up to March 2013 were found through a comprehensive electronic database search using PubMed, Embase, and The Cochrane Library. Two reviewers independently assessed the studies using strict inclusion criteria. Results: Nineteen studies were included and then qualitatively analyzed. In several of these, methodological problems were found. Moreover, intrarater and interrater reliability varied with the measure applied. A meta-analysis was not carried out as studies were not of sufficient quality to warrant doing so. Conclusion: In order to achieve reliable measurements in videofluoroscopy of swallowing, it is recommended that raters use well-defined guidelines for the levels of ordinal visuoperceptual variables. Furthermore, in order to make the measurements reliable (intrarater and interrater) it is recommended that, following protocolled pre-experimental training, the raters should have maximum consensus about the definition of the measured variables

    1984-01-01

    Swallows (Hirundo rustica) collected within the right-of-way of a major Maryland highway were greater than those found in Barn Swallows nesting within a rural area. Lead concentrations in the feathers of adults from the highway colony were also greater than Lead concentrations in the carcasses and stomach contents of adult and nestling Barn those of rural adults, but concentrations in the feathers of nestlings from the two locations were similar. Activity of u-aminolevulinic acid dehydratase in red blood cells was lower in highway-nesting adults and their young than in their rural counterparts, although hemoglobin concentrations and hematocrits did not differ. The number of eggs, nestlings, and body weights of the latter at 16-18 days of age were similar in the two colonies, as were body weights of adults from the two areas. These results suggest that contamination of roadside habitats by lead from automotive emissions does not pose a serious hazard to birds that are aerial feeders.

    We introduce a skin-friendly electronic system that enables human-computer interaction (HCI) for swallowing training in dysphagia rehabilitation. For an ergonomic HCI, we utilize a soft, highly compliant (“skin-like”) electrode, which addresses critical issues of an existing rigid and planar electrode combined with a problematic conductive electrolyte and adhesive pad. The skin-like electrode offers a highly conformal, user-comfortable interaction with the skin for long-term wearable, high-fidelity recording of swallowing electromyograms on the chin. Mechanics modeling and experimental quantification captures the ultra-elastic mechanical characteristics of an open mesh microstructured sensor, conjugated with an elastomeric membrane. Systematic in vivo studies investigate the functionality of the soft electronics for HCI-enabled swallowing training, which includes the application of a biofeedback system to detect swallowing behavior. The collection of results demonstrates clinical feasibility of the ergonomic electronics in HCI-driven rehabilitation for patients with swallowing disorders.

    We sought to determine whether maca, a Peruvian plant, is effective for selective-serotonin reuptake inhibitor (SSRI)-induced sexual dysfunction. We conducted a double-blind, randomized, parallel group dose-finding pilot study comparing a low-dose (1.5 g/day) to a high-dose (3.0 g/day) maca regimen in 20 remitted depressed outpatients (mean age 36+/-13 years; 17 women) with SSRI-induced sexual dysfunction. The Arizona Sexual Experience Scale (ASEX) and the Massachusetts General Hospital Sexual Function Questionnaire (MGH-SFQ) were used to measure sexual dysfunction. Ten subjects completed the study, and 16 subjects (9 on 3.0 g/day; 7 on 1.5 g/day) were eligible for intent-to-treat (ITT) analyses on the basis of having had at least one postbaseline visit. ITT subjects on 3.0 g/day maca had a significant improvement in ASEX (from 22.8+/-3.8 to 16.9+/-6.2; z=-2.20, P=0.028) and in MGH-SFQ scores (from 24.1+/-1.9 to 17.0+/-5.7; z=-2.39, P=0.017), but subjects on 1.5 g/day maca did not. Libido improved significantly (PMaca was well tolerated. Maca root may alleviate SSRI-induced sexual dysfunction, and there may be a dose-related effect. Maca may also have a beneficial effect on libido.

  1. Burden of Sexual Dysfunction.

    Similar to the burden of other diseases, the burden of sexual dysfunction has not been systematically studied. However, there is growing evidence of various burdens (e.g., economic, symptomatic, humanistic) among patients suffering from sexual dysfunctions. The burden of sexual dysfunction has been studied a bit more often in men, namely the burden of erectile dysfunction (ED), premature ejaculation (PE) and testosterone deficiency syndrome (TDS). Erectile dysfunction is frequently associated with chronic conditions such as cardiovascular disease, diabetes, and depression. These conditions could go undiagnosed, and ED could be a marker of those diseases. The only available report from the United Kingdom estimated the total economic burden of ED at £53 million annually in terms of direct costs and lost productivity. The burden of PE includes significant psychological distress: anxiety, depression, lack of sexual confidence, poor self-esteem, impaired quality of life, and interpersonal difficulties. Some suggest that increase in female sexual dysfunction is associated with partner's PE, in addition to significant interpersonal difficulties. The burden of TDS includes depression, sexual dysfunction, mild cognitive impairment, and osteoporosis. One UK estimate of the economic burden of female sexual dysfunctions demonstrated that the average cost per patient was higher than the per annum cost of ED. There are no data on burden of paraphilic disorders. The burden of sexual dysfunctions is underappreciated and not well studied, yet it is significant for both the patients and the society.

    To investigate the beneficial role of prebiotics on endothelial dysfunction, an early key marker of cardiovascular diseases, in an original mouse model linking steatosis and endothelial dysfunction. We examined the contribution of the gut microbiota to vascular dysfunction observed in apolipoprotein E knockout (Apoe -/- ) mice fed an n-3 polyunsaturated fatty acid (PUFA)-depleted diet for 12 weeks with or without inulin-type fructans (ITFs) supplementation for the last 15 days. Mesenteric and carotid arteries were isolated to evaluate endothelium-dependent relaxation ex vivo. Caecal microbiota composition (Illumina Sequencing of the 16S rRNA gene) and key pathways/mediators involved in the control of vascular function, including bile acid (BA) profiling, gut and liver key gene expression, nitric oxide and gut hormones production were also assessed. ITF supplementation totally reverses endothelial dysfunction in mesenteric and carotid arteries of n-3 PUFA-depleted Apoe -/- mice via activation of the nitric oxide (NO) synthase/NO pathway. Gut microbiota changes induced by prebiotic treatment consist in increased NO-producing bacteria, replenishment of abundance in Akkermansia and decreased abundance in bacterial taxa involved in secondary BA synthesis. Changes in gut and liver gene expression also occur upon ITFs suggesting increased glucagon-like peptide 1 production and BA turnover as drivers of endothelium function preservation. We demonstrate for the first time that ITF improve endothelial dysfunction, implicating a short-term adaptation of both gut microbiota and key gut peptides. If confirmed in humans, prebiotics could be proposed as a novel approach in the prevention of metabolic disorders-related cardiovascular diseases. Published by the BMJ Publishing Group Limited.

    Dysphagia is one of the primary symptoms experienced by individuals with Oculopharyngeal Muscular Dystrophy (OPMD). However, we lack understanding of the discrete changes in swallowing physiology that are seen in OPMD, and the resulting relationship to impairments of swallowing safety and efficiency. This study sought to describe the pathophysiology of dysphagia in a small sample of patients with OPMD using a videofluoroscopy examination (VFSS) involving 3 × 5 mL boluses of thin liquid barium (22% w/v). The aim of this study is to extend what is known about the pathophysiology of dysphagia in OPMD, by quantifying changes in swallow timing, kinematics, safety, and efficiency, measured from VFSS. This study is a secondary analysis of baseline VFSS collected from 11 adults (4 male), aged 48-62 (mean 57) enrolled in an industry-sponsored phase 2 therapeutic drug trial. Blinded raters scored the VFSS recordings for safety [Penetration-Aspiration Scale (PAS)], efficiency [Normalized Residue Ratio Scale (NRRS)], timing [Pharyngeal Transit Time (PTT), Swallow Reaction Time (SRT), Laryngeal Vestibule Closure Reaction Time (LVCrt), Upper Esophageal Sphincter Opening Duration (UESD)], and kinematics (hyoid movement, pharyngeal constriction, UES opening width). Impairment thresholds from existing literature were defined to characterize swallowing physiology and function. Further, Fisher's Exact tests and Pearson's correlations were used to conduct a preliminary exploration of associations between swallowing physiology (e.g., kinematics, timing) and function (i.e., safety, efficiency). Compared to published norms, we identified significant differences in the degree of maximum pharyngeal constriction, hyoid movement distance and speed, as well as degree and timeliness of airway closure. Unsafe swallowing (PAS ≥ 3) was seen in only 3/11 patients. By contrast, clinically significant residue (i.e., NRRS scores ≥ 0.09 vallecular; ≥ 0.2 pyriform) was seen in

    Purpose: Reduced hyolaryngeal elevation, a critical event in swallowing, is associated with radiation therapy. Two muscle groups that suspend the hyoid, larynx, and pharynx have been proposed to elevate the hyolaryngeal complex: the suprahyoid and longitudinal pharyngeal muscles. Thought to assist both groups is the thyrohyoid, a muscle intrinsic to the hyolaryngeal complex. Intensity modulated radiation therapy guidelines designed to preserve structures important to swallowing currently exclude the suprahyoid and thyrohyoid muscles. This study used muscle functional magnetic resonance imaging (mfMRI) in normal healthy adults to determine whether both muscle groups are active in swallowing and to test therapeutic exercises thought to be specific to hyolaryngeal elevation. Methods and Materials: mfMRI data were acquired from 11 healthy subjects before and after normal swallowing and after swallowing exercise regimens (the Mendelsohn maneuver and effortful pitch glide). Whole-muscle transverse relaxation time (T2 signal, measured in milliseconds) profiles of 7 test muscles were used to evaluate the physiologic response of each muscle to each condition. Changes in effect size (using the Cohen d measure) of whole-muscle T2 profiles were used to determine which muscles underlie swallowing and swallowing exercises. Results: Post-swallowing effect size changes (where a d value of >0.20 indicates significant activity during swallowing) for the T2 signal profile of the thyrohyoid was a d value of 0.09; a d value of 0.40 for the mylohyoid, 0.80 for the geniohyoid, 0.04 for the anterior digastric, and 0.25 for the posterior digastric-stylohyoid in the suprahyoid muscle group; and d values of 0.47 for the palatopharyngeus and 0.28 for the stylopharyngeus muscles in the longitudinal pharyngeal muscle group. The Mendelsohn maneuver and effortful pitch glide swallowing exercises showed significant effect size changes for all muscles tested, except for the thyrohyoid. Conclusions

    Full Text Available Abstract Background Swallowing accelerometry has been suggested as a potential non-invasive tool for bedside dysphagia screening. Various vibratory signal features and complementary measurement modalities have been put forth in the literature for the potential discrimination between safe and unsafe swallowing. To date, automatic classification of swallowing accelerometry has exclusively involved a single-axis of vibration although a second axis is known to contain additional information about the nature of the swallow. Furthermore, the only published attempt at automatic classification in adult patients has been based on a small sample of swallowing vibrations. Methods In this paper, a large corpus of dual-axis accelerometric signals were collected from 30 older adults (aged 65.47 ± 13.4 years, 15 male referred to videofluoroscopic examination on the suspicion of dysphagia. We invoked a reputation-based classifier combination to automatically categorize the dual-axis accelerometric signals into safe and unsafe swallows, as labeled via videofluoroscopic review. From these participants, a total of 224 swallowing samples were obtained, 164 of which were labeled as unsafe swallows (swallows where the bolus entered the airway and 60 as safe swallows. Three separate support vector machine (SVM classifiers and eight different features were selected for classification. Results With selected time, frequency and information theoretic features, the reputation-based algorithm distinguished between safe and unsafe swallowing with promising accuracy (80.48 ± 5.0%, high sensitivity (97.1 ± 2% and modest specificity (64 ± 8.8%. Interpretation of the most discriminatory features revealed that in general, unsafe swallows had lower mean vibration amplitude and faster autocorrelation decay, suggestive of decreased hyoid excursion and compromised coordination, respectively. Further, owing to its performance-based weighting of component classifiers, the static

    For persons with Parkinson's disease (PD), secondary motor symptoms such as swallow impairment impact the quality of life and are major contributors to mortality. There is a present need for therapeutic interventions aimed at improving swallow function during the early stages of PD. The purpose of this pilot study was to examine the effects of a group therapeutic singing intervention on swallowing in persons with PD with no significant dysphagia symptoms. Cohort study. University in the United States. Twenty-four participants with PD. Eight weeks of group therapeutic singing. Electromyography (EMG) was used to assess muscle activity associated with swallow pre and post the group singing intervention. Swallow quality of life (SWAL-QOL) and the Unified Parkinson's Disease Rating Scale (UPDRS) were also obtained pre- and post-intervention. Participants reported minimal difficulty with swallowing, yet results revealed a significant increase in EMG outcome measures, as well as significant improvement in UPDRS total and UPDRS motor scores. No significant differences were revealed for SWAL-QOL. Increases in EMG timing measures may suggest that group singing results in the prolongation of laryngeal elevation, protecting the airway from foreign material for longer periods of time during swallow. Combined with the improvement in UPDRS clinical measures, therapeutic singing may be an engaging early intervention strategy to address oropharyngeal dysphagia while also benefiting additional clinical symptoms of PD.

    The purpose of this review is to assess the current state of the literature on the topic of deep brain stimulation (DBS) and its effects on swallowing function in Parkinson’s disease (PD). Pubmed, Cochrane review, and web of science searches were completed on all articles addressing DBS that contained a swallowing outcome measure. Outcome measures included the penetration/aspiration scale, pharyngeal transit time, oropharyngeal residue, drooling, aspiration pneumonia, death, hyolaryngeal excursion, epiglottic inversion, UPDRS scores, and presence of coughing/throat clearing during meals. The search identified 13 studies specifically addressing the effects of DBS on swallowing. Critical assessment of the 13 identified peer-reviewed publications revealed nine studies employing an experimental design, (e.g. “on” vs. “off”, pre- vs. post-DBS) and four case reports. None of the nine experimental studies were found to identify clinically significant improvement or decline in swallowing function with DBS. Despite these findings, several common threads were identified across experimental studies and will be examined in this review. Additionally, available data demonstrate that, although subthalamic nucleus (STN) stimulation has been considered to cause more impairment to swallowing function than globus pallidus internus (GPi) stimulation, there are no experimental studies directly comparing swallowing function in STN vs. GPi. Moreover, there has been no comparison of unilateral vs. bilateral DBS surgery and the coincident effects on swallowing function. This review includes a critical analysis of all experimental studies and discusses methodological issues that should be addressed in future studies. PMID:23726461

    We investigated the appropriate hemodynamic parameters of functional near-infrared spectroscopy (fNIRS) to best differentiate the discomfort intensity related to swallowing in healthy subjects wearing different types of simulated dentures. Thirty-one subjects performed 4 sessions of water-swallowing task in a sitting position without or with wearing any one of the 3 simulated dentures under continuous fNIRS monitoring of the prefrontal cortex. The simulated dentures were consisted of a flat maxillary palatal bar and bilateral support attachment to the teeth and gum. The palatal bar positions were arranged along with the anterior, middle, or posterior areas of the upper jaw. The cumulative values of oxyhemoglobin and deoxyhemoglobin concentration changes were calculated for periods of 5 - 10 s from completion of swallowing. Subjective rating of swallowing-discomfort was the lowest without wearing denture and increased along with the palatal bar position placed from anterior to posterior. Cumulated deoxyhemoglobin signals calculated for 10 s post-swallowing event in the left frontopolar prefrontal cortex showed the best correlation with the subjective rating of discomfort in swallowing with dentures. These neurological signatures would be beneficial to detect swallowing discomfort in elderly denture wearers who have difficulty in communicating with dentists.

    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.

    After gastrectomy or esophagectomy, esophagogastrostomy and esophagojejunostomy are commonly used for reconstruction. Water-soluble contrast swallow is often used as a routine screening to exclude anastomotic leakage during the first postoperative week. In this retrospective study, the sensitivity and specificity of oral water-soluble contrast swallow for the detection of anastomotic leakage and its clinical symptoms were analysed. Records of 104 consecutive total gastrectomies and distal esophagectomies were analysed. In all cases, upper gastrointestinal contrast swallow with the use of a water-soluble contrast agent was performed on the 5 th postoperative day. Extravasation of the contrast agent was defined as anastomotic leakage. When anastomotic insufficiency was suspected but no extravasation was present, a computed tomography (CT) scan and upper endoscopy were performed. Oral contrast swallow detected 7 anastomotic leaks. Based on CT-scans and upper endoscopy, the true number of anastomotic leakage was 15. The findings of the oral contrast swallow were falsely positive in 4 and falsely negative in 12 patients, respectively. The sensitivity and specificity of the oral contrast swallow was 20% and 96%, respectively. Routine radiological contrast swallow following total gastrectomy or distal esophagectomy cannot be recommended. When symptoms of anastomotic leakage are present, a CT-scan and endoscopy are currently the methods of choice.

    Magnetic resonance imaging overcomes the limitations of videofluoroscopy in assessing without radiation exposure. The clinical utility of dynamic MRI for swallowing disorders is not well documented. This study demonstrates the feasibility of using dynamic MRI in assessment of swallowing disorders. Ten normal and three brainstem lesion patients participated in this study. GE Signa HDxt 1.5 Tesla MRI scanner with head-and-neck coil as a receiver and fast imaging employing steady state acquisition sequence was used. The swallow was analyzed in terms of symmetry and amplitude of movements of velum, faucial pillars, tongue, epiglottis and cricopharyngeous and images from the sagittal, coronal and axial planes. In sagittal plane posterior movement of tongue and its compression on velum, elevation of hyoid bone, elevation of larynx and lid action of epiglottis, in the coronal view the symmetrical movements of the faucial pillars and pharyngeal constrictor muscles and in axial plane three anatomical landmarks were targeted based on their role in swallowing, viz. velum, epiglottis and cricopharyngeous were studied. In brainstem lesion individuals, posterior movement of tongue, and elevation of larynx were not seen. Asymmetrical movements of faucial pillars and cricopharyngeous muscle were appreciated in the dynamic MRI. This demonstrates that, dynamic MRI is an efficient tool to understand the swallowing physiology and helps the speech language pathologist in modifying the swallowing maneuvers. Dynamic MRI is an effective tool in assessing swallowing and its disorders. This muscle specific information is not appreciated in videofluoroscopy and this information is necessary to modify the therapy maneuvers.

    This study aimed to elucidate the relationship between the piezoelectric waveform latency, hyoid bone movement, surface electromyogram (sEMG), and the pharyngeal transit time (PTT) during swallowing. Forty-one healthy subjects were divided into three age groups: younger (20-39 years, n = 8), middle-aged (40-59 years, n = 9), and older (60-79 years, n = 24). Motion analysis of the hyoid bone using videofluorography (VF), waveform analysis of the front neck using piezoelectric films, and sEMG of the suprahyoid muscle group were performed simultaneously. Latencies of the three movement phases were defined as upward (VFS1), forward (VFS2), and returning to starting position (VFS3). The three phases of the piezoelectric waveform-from wave initiation of the negative wave to the start of the second deep negative wave; from the start of the second deep negative wave to the start of the last positive wave (SLPW); and from the SLPW to the end of the last positive wave-were defined as PS1, PS2, and PS3, respectively. VFS1-3 and PS1-3 were significantly correlated. VFS1 and PS1 latencies were significantly longer with thick liquid than with thin liquid. VFS2, PS1, and PS2 latencies were longer in the older group than in the other two groups. The start of PS1 was nearly equal to those of sEMG and VFS1. Bolus arrival time in the valleculae was statistically equal to the end of the PS1 with both thin and thick liquids. To establish the swallowing screening using Piezoelectric film, further investigation is necessary in the dysphagia patients.

    The aim of this study was to determine if bolus and dry swallow showed similar pressure changes in the oropharynx using our newly developed device. A unique character of it includes that baropressure can be measured with the sensor being placed in the balloon and can assess the swallowing mechanics in terms of pressure changes in the oropharynx with less influences of direct contacts of boluses and oropharyngeal structures during swallow indirectly. Fifteen healthy subjects swallowed saliva (dry), 15 ml of water, 45 ml of water, and 15 ml of two different types of food in terms of viscosity (potage soup-type and mayonnaise-type foods). Suprahyoid muscle activity was recorded simultaneously. Three parameters, area under the curve (AUC), peak amplitude, and duration of pressure, were analyzed from each swallow. Almost all of the bolus swallowing events had biphasic baropressure responses consisting of an early phase and late phase (99%), whereas 90% of the saliva swallowing events had a single phase. AUC, peak, and duration displayed greater effects during the late phase than during the early phase. Baropressure of the early phase, but not of the late phase, significantly increased with increasing volume; however, small but significant viscosity effects on pressure were seen during both phases. Peak pressure of the late phase was preceded by maximum muscle activity, whereas that of the early phase was seen when muscle activity displayed a peak response. These findings indicated that our device with the ability to measure baropressure has the potential to provide additional parameter to assess the swallow physiology, and biphasic baropressure responses in the early and late phases could reflect functional aspects of the swallowing reflexes.

    In order to evaluate the neuronal mechanisms underlying functional abnormalities of swallowing in orofacial pain patients, this study investigated the effects of noxious orofacial stimulation on the swallowing reflex, phosphorylated extracellular signal-regulated kinase (pERK) and γ-aminobutyric acid (GABA) immunohistochemical features in brainstem neurons, and also analysed the effects of brainstem lesioning and of microinjection of GABA receptor agonist or antagonist into the nucleus tractus solitarii (NTS) on the swallowing reflex in anaesthetized rats. The swallowing reflex elicited by topical administration of distilled water to the pharyngolaryngeal region was inhibited after capsaicin injection into the facial (whisker pad) skin or lingual muscle. The capsaicin-induced inhibitory effect on the swallowing reflex was itself depressed after the intrathecal administration of MAPK kinase (MEK) inhibitor. No change in the capsaicin-induced inhibitory effect was observed after trigeminal spinal subnucleus caudalis lesioning, but the inhibitory effect was diminished by paratrigeminal nucleus (Pa5) lesioning. Many pERK-like immunoreactive neurons in the NTS showed GABA immunoreactivity. The local microinjection of the GABAA receptor agonist muscimol into the NTS produced a significant reduction in swallowing reflex, and the capsaicin-induced depression of the swallowing reflex was abolished by microinjection of the GABAA receptor antagonist bicuculline into the NTS. The present findings suggest that facial skin–NTS, lingual muscle–NTS and lingual muscle–Pa5–NTS pathways are involved in the modulation of swallowing reflex by facial and lingual pain, respectively, and that the activation of GABAergic NTS neurons is involved in the inhibition of the swallowing reflex following noxious stimulation of facial and intraoral structures.

    Full Text Available Background: Barium swallow is performed following esophagectomy to evaluate the anastomosis for detection of leaks and to assess the emptying of the gastric conduit. The aim of this study was to evaluate the reliability of the barium swallow study in diagnosing anastomotic leaks following esophagectomy. Methods: Patients who underwent esophagectomy from January 2000 to December 2013 at our institution were investigated. Barium swallow was routinely done between days 5–7 to detect a leak. These results were compared to clinically determined leaks (defined by neck wound infection requiring jejunal feeds and or parenteral nutrition during the postoperative period. The sensitivity and specificity of barium swallow in diagnosing clinically significant anastomotic leaks was determined. Results: A total of 395 esophagectomies were performed (mean age, 62.2 years. The indications for the esophagectomy were as follows: malignancy (n=320, high-grade dysplasia (n=14, perforation (n=27, benign stricture (n=7, achalasia (n=16, and other (n=11. A variety of techniques were used including transhiatal (n=351, McKeown (n=35, and Ivor Lewis (n=9 esophagectomies. Operative mortality was 2.8% (n=11. Three hundred and sixty-eight patients (93% underwent barium swallow study after esophagectomy. Clinically significant anastomotic leak was identified in 36 patients (9.8%. Barium swallow was able to detect only 13/36 clinically significant leaks. The sensitivity of the swallow in diagnosing a leak was 36% and specificity was 97%. The positive and negative predictive values of barium swallow study in detecting leaks were 59% and 93%, respectively. Conclusion: Barium swallow is an insensitive but specific test for detecting leaks at the cervical anastomotic site after esophagectomy.

    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.

    Schizotypy is a personality organisation that is closely related to schizotypal personality disorder and schizophrenia and is characterised by deficits in social functioning. Although the dimensions of social dysfunction have not yet been fully explored certain aspects of social dysfunction are promising predictive markers for schizophrenia. To describe schizotypy and its influence on social functioning. We reviewed the literature systematically using the online databases PubMed and PsycINFO. The disorder known as schizotypy lies at the basis of schizotypal personality disorder. Both disorders are characterised by an increased risk for schizophrenia. The social dysfunctioning seen in schizotypy corresponds to the social dysfunction seen in schizophrenia. Impairments in social cognition are causal factors of this social dysfunction. Both the negative and the positive dimension of schizotypy influence social cognition. More focused, objective and interactive research to the various aspects of social functioning in schizotypy is needed in order to discover potential premorbid markers for schizophrenia.

    Unilateral vocal fold immobility (UVFI) results in deficits in phonatory, respiratory, and swallow function of the pediatric patient. Little is known about long-term functional swallow outcomes. Medical records of children diagnosed with UVFI between 2005 and 2014 at a tertiary children's hospital were retrospectively reviewed. Etiology, laryngoscopy findings, and swallow status at diagnosis and follow-up were recorded. Swallow outcomes were compared by etiology using Fisher's exact test. McNemar's test was used to identify correlations between return of mobility and swallow recovery. Rates of pneumonia were compared with initial swallow evaluation results using a two-tailed t-test. Eighty-eight patients with UVFI were identified and 73 patients (47% female, mean age 14.4 months, standard deviation (SD) 26.7 months) had complete medical records. Mean follow up time was 52.7 months (SD 36.8 months). Etiologies included cardiothoracic surgery (68.5%), idiopathic (12.3%), prolonged intubation (11.0%), central nervous system (CNS) abnormality (5.5%), and non-cardiac iatrogenic injury to the recurrent laryngeal nerve (2.7%). Forty-seven patients underwent a follow up laryngoscopy, and recovery of vocal fold (VF) mobility was documented in 42.6% (20/47). At diagnosis, 31.5% fed orally, compared with 79.5% at follow-up. Direct correlation between recovery of VF mobility and swallow recovery was not demonstrated. Cardiac etiologies demonstrated higher rates of swallow recovery than CNS abnormalities (p = 0.0393). Twenty-five children aspirated on initial modified barium swallow (MBS) and 10 children developed pneumonias at some point during the follow up period. There was no significant difference in rates of pneumonia in patients with and without aspiration on MBS. Recovery of swallow in children with UVFI does not directly parallel return of VF mobility. Long-term swallow outcome is favorable in this population. Initial MBS does not indicate ultimate swallow outcome

    Erectile dysfunction is common in the patient with cardiovascular disease. It is an important component of the quality of life and it also confers an independent risk for future cardiovascular events. The usual 3-year time period between the onset of erectile dysfunction symptoms and a cardiovascular event offers an opportunity for risk mitigation. Thus, sexual function should be incorporated into cardiovascular disease risk assessment for all men. A comprehensive approach to cardiovascular risk reduction (comprising of both lifestyle changes and pharmacological treatment) improves overall vascular health, including sexual function. Proper sexual counselling improves the quality of life and increases adherence to medication. This review explores the critical connection between erectile dysfunction and cardiovascular disease and evaluates how this relationship may influence clinical practice. Algorithms for the management of patient with erectile dysfunction according to the risk for sexual activity and future cardiovascular events are proposed.

    Full Text Available Satisfying sexual experience is an essential part of a healthy and enjoyable life for most people. Antipsychotic drugs are among the various factors that affect optimal sexual functioning. Both conventional and novel antipsychotics are associated with significant sexual side effects. This review has presented various studies comparing different antipsychotic drugs. Dopamine antagonism, increased serum prolactin, serotonergic, adrenergic and cholinergic mechanisms are all proposed to be the mechanisms for sexual dysfunction. Drug treatment for this has not given satisfactory long-term results. Knowledge of the receptor pharmacology of an individual antipsychotic will help to determine whether it is more or less likely to cause sexual side effects and its management.

    Conclusions: Present study shows that although diastolic dysfunction is a frequent event in cirrhosis, it is usually of mild degree and does not correlate with severity of liver dysfunction. There are no significant differences in echocardiographic parameters between alcoholic and non-alcoholic cirrhosis. HRS is not correlated to diastolic dysfunction in cirrhotic patients. There is no difference in survival at one year between patients with or without diastolic dysfunction. Diastolic dysfunction in cirrhosis is unrelated to circulatory dysfunction, ascites and HRS.

    Early involvement of gut is observed in Parkinson’s disease (PD) and symptoms such as constipation may precede motor symptoms. α-Synuclein pathology is extensively evident in the gut and appears to follow a rostrocaudal gradient. The gut may act as the starting point of PD pathology with spread toward the central nervous system. This spread of the synuclein pathology raises the possibility of prion-like propagation in PD pathogenesis. Recently, the role of gut microbiota in PD pathogenesis has received attention and some phenotypic correlation has also been shown. The extensive involvement of the gut in PD even in its early stages has led to the evaluation of enteric α-synuclein as a possible biomarker of early PD. The clinical manifestations of gastrointestinal dysfunction in PD include malnutrition, oral and dental disorders, sialorrhea, dysphagia, gastroparesis, constipation, and defecatory dysfunction. These conditions are quite distressing for the patients and require relevant investigations and adequate management. Treatment usually involves both pharmacological and non-pharmacological measures. One important aspect of gut dysfunction is its contribution to the clinical fluctuations in PD. Dysphagia and gastroparesis lead to inadequate absorption of oral anti-PD medications. These lead to response fluctuations, particularly delayed-on and no-on, and there is significant relationship between levodopa pharmacokinetics and gastric emptying in patients with PD. Therefore, in such cases, alternative routes of administration or drug delivery systems may be required. PMID:27433087

    The utility of short TR single shot fast spin echo (SSFSE) MR imaging for evaluating swallowing was determined. Five healthy volunteers underwent kinematic MR imaging of swallowing with a 1.5 T MR scanner using the short TR (300 ms) SSFSE sequence. Twenty phases of sagittal sections were acquired within 6 sec, where the temporal resolution was 300 ms. For oral contrast medium, we used prune yogurt juice with Fe added. The image contrast of short TR SSFSE was found to be somewhere like that of T1-weighted images. In all cases, both the buccal and pharyngeal stages of swallowing were successfully depicted. The Fe-added prune yogurt juice performed as a positive contrast medium and helped determine anatomical structures in the buccal stage. Short TR (300 ms) SSFSE was useful in evaluating swallowing. The combined use of Fe-added prune yogurt juice was helpful in enhancing the surface of the oropharynx. (author)

    2010-01-01

    Full Text Available Fast Hermite projections have been often used in image-processing procedures such as image database retrieval, projection filtering, and texture analysis. In this paper, we propose an innovative approach for the analysis of one-dimensional biomedical signals that combines the Hermite projection method with time-frequency analysis. In particular, we propose a two-step approach to characterize vibrations of various origins in swallowing accelerometry signals. First, by using time-frequency analysis we obtain the energy distribution of signal frequency content in time. Second, by using fast Hermite projections we characterize whether the analyzed time-frequency regions are associated with swallowing or other phenomena (vocalization, noise, bursts, etc.. The numerical analysis of the proposed scheme clearly shows that by using a few Hermite functions, vibrations of various origins are distinguishable. These results will be the basis for further analysis of swallowing accelerometry to detect swallowing difficulties.

    The purpose of this study was to evaluate if subjective symptoms indicating an impaired deglutition correlate with videofluoroscopic findings in patients with multiple sclerosis (MS). Videofluoroscopic examinations of 18 MS patients were analyzed by a radiologist and a logopedist and compared with the symptoms of these patients. Four patients complained about permanent dysphagia. Six patients reported mild and intermittent difficulties in swallowing, but were asymptomatic at the time of videofluoroscopy. Eight patients had no symptoms regarding their deglutition. All patients (n=4) who complained of permanent dysphagia showed aspiration. All patients (n=6) with mild and intermittent difficulties in swallowing showed undercoating of the epiglottis and/or laryngeal penetration. Of those 8 patients without any swallowing symptoms, only 2 had a normal videofluoroscopy. Swallowing abnormalities seem to be much more frequent in patients with MS than generally believed and they may easily be missed clinically as long as the patients do not aspirate. (orig.)

    Surgical procedures for colonic replacement of the esophagus are most commonly associated with anastomotic stricture which cause dysphagia. In this report, we describe a rare case of a patient who demonstrated dysphagia resulting from an anastomotic stricture following esophageal replacement with the colon. All the treatments to dilate the anastomotic stricture were ineffective. To investigate the new treatment strategy for a case with complicated dysphagia, clinical dysphagia evaluations, functional oral intake scale (FOIS), videofluoroscopic swallowing study as well as high-resolution manometry were used to evaluate the swallowing function of the patient before and after treatments. Comprehensive swallowing exercises included the protective airway maneuver, tongue pressure resistance feedback exercise, Masako Maneuver swallowing exercise, and the effortful swallowing exercise. Comprehensive swallowing exercises showed good effect in the patient. The FOIS score increased from level 1 to level 7. The videofluoroscopy digital analysis showed that the pharynx constriction rate was 23% and 50%, before and after treatment, respectively. The data from the high-resolution manometry displayed that: the value of the velopharyngeal pressure peak was 82.8 mmHg before treatment and 156.9 mmHg after treatment; the velopharyngeal contraction duration time was 310 milliseconds before treatment and 525 milliseconds after treatment; the value of the hypopharynx pressure peak was 53.7 mmHg before treatment and 103.2 mmHg after treatment; and the hypopharynx contraction duration time was 390 milliseconds before treatment and 1030 milliseconds after treatment. The swallowing visualization illustrated that a bolus could normally pass through the anastomotic stoma, and the bolus leakage was no longer present. The patient was able to eat various consistencies of food independently, and we were able to remove the jejunum nutrient catheter before discharging the patient. For

We investigated the hypothesis that meal consumption may reduce tongue strength and endurance in older adults (OAs.Methods: Tongue–palate pressure, oral diadochokinesis, repetitive saliva swallowing, and surface electromyography activity before and after a meal were measured in 23 young adults (YAs and 23 OA volunteers.Results: There was a statistically significant difference in both tongue pressure and the number of voluntary swallows between YAs and OAs. Peak tongue pressure was significantly lower in OAs than YAs both before and after meal consumption. The most notable finding was that the first time interval (the time from test initiation to the beginning of the first swallow was prolonged after meal consumption only in OAs, whereas the first time interval showed no difference between YAs and OAs before meal consumption with reference to the repetitive saliva swallowing test. The initiation of swallowing was prolonged by both meal consumption and aging; there was a significant interaction between these two factors. The number of repetitions of the monosyllable/pa/was statistically similar between YAs and OAs before meal consumption, but it was significantly lower in OAs after meal consumption.Conclusion: Aging leads to declining tongue pressure and motor function of the lips. It is possible that swallowing function declines in older individuals when meal consumption is prolonged, especially at the end of mealtime, as a result of their

    The swallowing reflex is centrally programmed by the lower brain stem, the so-called swallowing central pattern generator (CPG), and once the reflex is initiated, many muscles in the oral, pharyngeal, laryngeal, and esophageal regions are systematically activated. The mylohyoid (MH) muscle has been considered to be a "leading muscle" according to previous studies, but the functional role of the digastric (DIG) muscle in the swallowing reflex remains unclear. In the present study, therefore, the activities of single units of MH and DIG neurons were recorded extracellularly, and the functional involvement of these neurons in the swallowing reflex was investigated. The experiments were carried out on eight adult male Japanese white rabbits anesthetized with urethane. To identify DIG and MH neurons, the peripheral nerve (either DIG or MH) was stimulated to evoke action potentials of single motoneurons. Motoneurons were identified as such if they either (1) responded to antidromic nerve stimulation of DIG or MH in an all-or-none manner at threshold intensities and (2) followed stimulation frequencies of up to 0.5 kHz. As a result, all 11 MH neurons recorded were synchronously activated during the swallowing reflex, while there was no activity in any of the 7 DIG neurons recorded during the swallowing reflex. All neurons were anatomically localized ventromedially at the level of the caudal portion of the trigeminal motor nucleus, and there were no differences between the MH and DIG neuron sites. The present results strongly suggest that at least in the rabbit, DIG motoneurons are not tightly controlled by the swallowing CPG and, hence, the DIG muscle is less involved in the swallowing reflex.

    Swallowing is triggered when a food bolus being prepared by mastication has reached a defined state. However, although this view is consensual and well supported, the physical properties of the swallowable bolus have been under-researched. We tested the hypothesis that measuring bolus physical changes during the masticatory sequence to deglutition would reveal the bolus properties potentially involved in swallowing initiation. Twenty normo-dentate young adults were instructed to chew portions of cereal and spit out the boluses at different times in the masticatory sequence. The mechanical properties of the collected boluses were measured by a texture profile analysis test currently used in food science. The median particle size of the boluses was evaluated by sieving. In a simultaneous sensory study, twenty-five other subjects expressed their perception of bolus texture dominating at any mastication time. Several physical changes appeared in the food bolus as it was formed during mastication: (1) in rheological terms, bolus hardness rapidly decreased as the masticatory sequence progressed, (2) by contrast, adhesiveness, springiness and cohesiveness regularly increased until the time of swallowing, (3) median particle size, indicating the bolus particle size distribution, decreased mostly during the first third of the masticatory sequence, (4) except for hardness, the rheological changes still appeared in the boluses collected just before swallowing, and (5) physical changes occurred, with sensory stickiness being described by the subjects as a dominant perception of the bolus at the end of mastication. Although these physical and sensory changes progressed in the course of mastication, those observed just before swallowing seem to be involved in swallowing initiation. They can be considered as strong candidates for sensory inputs from the bolus that are probably crucially involved in the triggering of swallowing, since they appeared in boluses prepared in various

    The aim of this study was to investigate the possible correlation between otitis media with effusion, bad sucking habits and atypical swallowing in children affected by otitis media with effusion. 65 children, aged from 7 to 12 years, observed in the ENT Department of the "La Sapienza" University of Rome, were enrolled in the study group (group A). All children were affected by otitis media with effusion for more than 3 months. As control group, 60 healthy children, aged from 7 to 12 years were identified (group B). All the children underwent medical history, with evaluation of the sucking habits, ENT examination, tympanometry, orthodontic examination and evaluation of swallowing. In the orthodontic examination the variables analyzed were: maximum mouth opening, right and left mandibular lateral movements and mandibular protrusion. Atypical swallowing was considered to occur when lip activity produced strong tension in the perioral musculature, and/or the tip of the tongue was placed or pushed against the anterior teeth during swallowing. In the group A, atypical swallowing was found in 33/65 subjects out of the 65 children (50.7%). In the control group (group B) 16/60 children (26.6%) showed atypical swallowing. Compared with group B, deleterious sucking habits were significantly higher (phabits were present in almost all children with atypical swallowing (28/33 in group A and 12/16 in group B). Our data suggest a correlation between otitis media with effusion, deleterious sucking habits and prevalence of atypical swallowing. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    People with Parkinson’s disease (PD) suffer from progressive impairment in their mobility. Locomotor and balance dysfunction that impairs mobility in PD is an important cause of physical and psychosocial disability. The recognition and evaluation of balance dysfunction by the clinician is an essential component of managing PD. In this review, we describe a framework for understanding balance dysfunction in PD to help clinicians recognize patients that are at risk for falling and impaired mobility. PMID:23925954

    Full Text Available 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

    Background Oropharyngeal dysphagia (OD) is an underdiagnosed digestive disorder that causes severe nutritional and respiratory complications. Our aim was to determine the accuracy of the Eating Assessment Tool (EAT-10) and the Volume-Viscosity Swallow Test (V-VST) for clinical evaluation of OD. Methods We studied 120 patients with swallowing difficulties and 14 healthy subjects. OD was evaluated by the 10-item screening questionnaire EAT-10 and the bedside method V-VST, videofluoroscopy (VFS) being the reference standard. The V-VST is an effort test that uses boluses of different volumes and viscosities to identify clinical signs of impaired efficacy (impaired labial seal, piecemeal deglutition, and residue) and impaired safety of swallow (cough, voice changes, and oxygen desaturation ≥3%). Discriminating ability was assessed by the AUC of the ROC curve and sensitivity and specificity values. Key Results According to VFS, prevalence of OD was 87%, 75.6% with impaired efficacy and 80.9% with impaired safety of swallow including 17.6% aspirations. The EAT-10 showed a ROC AUC of 0.89 for OD with an optimal cut-off at 2 (0.89 sensitivity and 0.82 specificity). The V-VST showed 0.94 sensitivity and 0.88 specificity for OD, 0.79 sensitivity and 0.75 specificity for impaired efficacy, 0.87 sensitivity and 0.81 specificity for impaired safety, and 0.91 sensitivity and 0.28 specificity for aspirations. Conclusions & Inferences Clinical methods for screening (EAT-10) and assessment (V-VST) of OD offer excellent psychometric proprieties that allow adequate management of OD. Their universal application among at-risk populations will improve the identification of patients with OD at risk for malnutrition and aspiration pneumonia. PMID:24909661

    Full Text Available Swallowing disorders are not uncommon among elderly and people affected by neurological diseases. For these patients the ingestion of solid grains, such as pharmaceutical oral solid formulations, could result in choking. This generally results in a low compliance in taking solid medications. The effect of the solid medication size on the real or perceived ease of swallowing is still to be understood from the mechanistic viewpoint. The interplay of the inclusion shape and the rheology of the liquid being swallowed together with the medication is also not fully understood. In this study, a model experiment was developed to study the oropharyngeal phase of swallowing, replicating the dynamics of the bolus flow induced by the tongue (by means of a roller driven by an applied force. Experiments were performed using a wide set of solid inclusions, dispersed in a thick Newtonian liquid. Predictions for a simple theory are compared with experiments. Results show that an increase in the grain size results in a slower dynamics of the swallowing. Furthermore, the experiments demonstrated the paramount role of shape, as flatter and more streamlined inclusions flow faster than spherical. This approach can support the design of new oral solid formulations that can be ingested more easily and effectively also by people with mild swallowing disorders.

    To determine swallowing outcomes and hyolaryngeal mechanics associated with post radiation therapy head and neck cancer (rtHNC) patients using videofluoroscopic swallow studies. In this retrospective cohort study, videofluoroscopic images of rtHNC patients (n = 21) were compared with age and gender matched controls (n = 21). Penetration-aspiration of the bolus and bolus residue were measured as swallowing outcome variables. Timing and displacement measurements of the anterior and posterior muscular slings elevating the hyolaryngeal complex were acquired. Coordinate data of anatomical landmarks mapping the action of the anterior muscles (suprahyoid muscles) and posterior muscles (long pharyngeal muscles) were used to calculate the distance measurements, and slice numbers were used to calculate time intervals. Canonical variate analysis with post-hoc discriminant function analysis was performed on coordinate data to determine multivariate mechanics of swallowing associated with treatment. Pharyngeal constriction ratio (PCR) was also measured to determine if weak pharyngeal constriction is associated with post radiation therapy. The rtHNC group was characterized by poor swallowing outcomes compared to the control group in regards to: Penetration-aspiration scale (P time of displacement was abbreviated (P = 0.002) and distance of excursion was reduced (P = 0.02) in the rtHNC group. A canonical variate analysis shows a significant reduction in pharyngeal mechanics in the rtHNC group (P clearance. Using videofluoroscopy, this study shows rtHNC patients have worse swallowing outcomes associated with reduced hyolaryngeal mechanics and pharyngeal constriction compared with controls.

  6. The Food Contaminant Mycotoxin Deoxynivalenol Inhibits the Swallowing Reflex in Anaesthetized Rats.

    Directory of Open Access Journals (Sweden)

    Anne Abysique

    Full Text Available Deoxynivalenol (DON, one of the most abundant mycotoxins found on cereals, is known to be implicated in acute and chronic illnesses in both humans and animals. Among the symptoms, anorexia, reduction of weight gain and decreased nutrition efficiency were described, but the mechanisms underlying these effects on feeding behavior are not yet totally understood. Swallowing is a major motor component of ingestive behavior which allows the propulsion of the alimentary bolus from the mouth to the esophagus. To better understand DON effects on ingestive behaviour, we have studied its effects on rhythmic swallowing in the rat, after intravenous and central administration. Repetitive electrical stimulation of the superior laryngeal nerve or of the tractus solitarius, induces rhythmic swallowing that can be recorded using electromyographic electrodes inserted in sublingual muscles. Here we provide the first demonstration that, after intravenous and central administration, DON strongly inhibits the swallowing reflex with a short latency and in a dose dependent manner. Moreover, using c-Fos staining, a strong neuronal activation was observed in the solitary tract nucleus which contains the central pattern generator of swallowing and in the area postrema after DON intravenous injection. Our data show that DON modifies swallowing and interferes with central neuronal networks dedicated to food intake regulation.

    This study aimed to investigate whether the jaw-opening (JOR) and jaw-closing reflexes (JCR) are modulated during not only peripherally, but also centrally, evoked swallowing. Experiments were carried out on 24 adult male Japanese white rabbits. JORs were evoked by trigeminal stimulation at 1 Hz for 30 sec. In the middle 10 sec, either the superior laryngeal nerve (SLN) or cortical swallowing area (Cx) was simultaneously stimulated to evoke swallowing. The peak-to-peak JOR amplitude was reduced during the middle and late 10-sec periods (i.e., during and after SLN or Cx stimulation), and the reduction was dependent on the current intensity of SLN/Cx stimulation: greater SLN/Cx stimulus current resulted in greater JOR inhibition. The reduction rate was significantly greater during Cx stimulation than during SLN stimulation. The amplitude returned to baseline 2 min after 10-sec SLN/Cx stimulation. The effect of co-stimulation of SLN and Cx was significantly greater than that of SLN stimulation alone. There were no significant differences in any parameters of the JCR between conditions. These results clearly showed that JOR responses were significantly suppressed, not only during peripherally evoked swallowing but also during centrally evoked swallowing, and that the inhibitory effect is likely to be larger during centrally compared with peripherally evoked swallowing. The functional implications of these results are discussed. Copyright © 2018. Published by Elsevier B.V.

    Medialization thyroplasty was effective in improving swallowing function as well as vocal function in most cases with unilateral vocal fold paralysis. The impact of medialization thryoplasty was insufficient for the case with severe atrophy and that in which the vocal fold was fixed in the lateral position. To evaluate the impacts and limitations of medialization thyroplasty on swallowing function of the patients with unilateral vocal fold paralysis. Eight cases (mean age 68.5 years) with unilateral vocal fold paralysis chiefly complaining of swallowing disturbance were studied. All patients underwent thyroplasty type I. The causes of the paralysis were lung cancer in four cases, esophageal cancer in one case, aortic aneurysm in one case, subarachnoid hemorrhage in one case, and unknown in one case. Subjective swallowing function score, maximum phonation time (MPT), mean flow rate (MFR), amplitude perturbation quotient (APQ), and pitch perturbation quotient (PPQ) were examined pre- and postoperatively. The swallowing score improved in all except two cases. However, bilateral thryoplasty was necessary for the case with severe vocal fold atrophy and arytenoid adduction was needed for the case in which the vocal fold was fixed in the lateral position. The swallowing score, MPT, and MFR showed significant improvement after surgery.

    Sacroiliac joint dysfunction is a disorder presenting with low back and groin pain. It should be taken into consideration during the preoperative differential diagnosis of lumbar disc herniation, lumbar spinal stenosis and facet syndrome. Four cases with sacroiliac dysfunction are presented. The clinical and radiological signs supported the evidence of sacroiliac dysfunction, and exact diagnosis was made after positive response to sacroiliac joint block. A percutaneous sacroiliac fixation provided pain relief in all cases. The mean VAS scores reduced from 8.2 to 2.2. It is concluded that sacroiliac joint dysfunction diagnosis requires a careful physical examination of the sacroiliac joints in all cases with low back and groin pain. The diagnosis is made based on positive response to the sacroiliac block. Sacroiliac fixation was found to be effective in carefully selected cases.

    Aim: To determine whether radiographers are able to perform and interpret barium swallows and meals (BSM) to an acceptable standard. Materials and methods: A retrospective audit was performed of all radiographer-managed BSMs over a 4-year period in an acute hospital. Descriptive statistics were used to analyse patient demographics, radiation doses, referral sources, and imaging findings. Radiographer reports were compared with radiologist reports assumed to be the reference standard, and correlated with patient outcomes via electronic record searches and case note scrutiny. Reporting accuracy, sensitivity, and specificity were calculated. Results: Three radiographers performed a total of 962 BSMs in the 4-year audit period, including a varied and complex case-mix. Only 13 (0.01%) cases were abandoned due to technical reasons, with all other examinations of diagnostic quality. Although radiation dose levels were initially variable, following the installation of modern fluoroscopy equipment they remained comfortably within the national and regional diagnostic reference levels. Consultant radiologists verified the majority of the radiographer reports, with the most experienced radiographer independently reporting 230 cases (24%). Follow-up of patient outcome was possible in 935 cases. The overall radiographer accuracy based on the 935 cases was 98.9%, sensitivity 98%, and specificity 98.9%. Conclusions: Appropriately trained radiographers are able to perform and interpret BSM examinations to a very high standard.

  14. Swallowable fluorometric capsule for wireless triage of gastrointestinal bleeding.

    Real-time detection of gastrointestinal bleeding remains a major challenge because there does not yet exist a minimally invasive technology that can both i) monitor for blood from an active hemorrhage and ii) uniquely distinguish it from blood left over from an inactive hemorrhage. Such a device would be an important tool for clinical triage. One promising solution, which we have proposed previously, is to inject a fluorescent dye into the blood stream and to use it as a distinctive marker of active bleeding by monitoring leakage into the gastrointestinal tract with a wireless fluorometer. This paper reports, for the first time to our knowledge, the development of a swallowable, wireless capsule with a built-in fluorometer capable of detecting fluorescein in blood, and intended for monitoring gastrointestinal bleeding in the stomach. The embedded, compact fluorometer uses pinholes to define a microliter sensing volume and to eliminate bulky optical components. The proof-of-concept capsule integrates optics, low-noise analog sensing electronics, a microcontroller, battery, and low power Zigbee radio, all into a cylindrical package measuring 11 mm × 27 mm and weighing 10 g. Bench-top experiments demonstrate wireless fluorometry with a limit-of-detection of 20 nM aqueous fluorescein. This device represents a major step towards a technology that would enable simple, rapid detection of active gastrointestinal bleeding, a capability that would save precious time and resources and, ultimately, reduce complications in patients.

    The purpose of the study reported in this article was to tabulate the incidence and etiologic factors of importance in the development of strictures after radiotherapy for carcinoma of the esophagus and to analyze the outcome of patients who develop such strictures. Eighty patients were treated with radiotherapy, 50 having radical and 30 having palliative treatment. Sixty-nine patients had squamous cell carcinoma, four had adenocarcinoma, one had sarcoma, one had mucoepidermoid carcinoma, and five had undifferentiated tumors. Forty percent developed no stricture, 30% had benign fibrotic stricture, and 28% developed malignant stricture. The etiologic factors analysed included age, pretreatment swallowing score, histology and length (size) of tumor; stage of disease, dose of radiotherapy, and use of chemotherapy. None of these factors were shown to be of etiologic importance. The survival of patients who developed benign strictures was found to be significantly longer (1-year survival 88%) than those who developed no stricture (50%) or malignant stricture (19%). Using a success score for palliation of dysphagia, it was found that the majority of patients (71%) who developed a benign stricture had a moderately successful outcome--they were able to tolerate a full or soft diet and required dilatation with a median duration between dilatations of 5 months. Patients who developed a malignant stricture were palliated poorly by dilatation alone, and most required esophageal intubation

    Dysphagia is a clinically relevant symptom in patients with Parkinson's disease (PD) leading to pronounced reduction in quality of life and other severe complications. Parkinson's disease-related dysphagia may affect the oral and pharyngeal, as well as the esophageal phase of swallowing. To examine the nature and extend of esophageal dysphagia in different stages of PD and their relation to oropharyngeal dysfunction, we examined 65 PD patients (mean age 66.3±9.7 years, mean disease duration 7.9±5.8 years, mean Hoehn & Yahr [H&Y] stage 2.89±0.91) and divided into three groups (early [H&Y I+II; n=21], intermediate [H&Y III; n=25], and advanced stadium [H&Y IV+V; n=19]), using esophageal high-resolution manometry (HRM) to detect esophageal motor disorders. Oropharyngeal impairment was assessed using fiberoptic endoscopic evaluation of swallowing. Major esophageal motor disorders were detected in nearly one third of the PD patients. Minor impairment of the esophageal body was present in 95% of participants and throughout all disease stages with pathological findings especially in peristalsis and intrabolus pressure (IBP). The IBP was found to significantly increase in the advanced stadium. Although dysfunction of the upper and lower esophageal sphincters was observed in individual patients, alterations in these esophageal segments revealed no statistical significance compared with normative data. No clear association was found between the occurrence of oropharyngeal dysphagia and esophageal impairment. Esophageal body impairment in PD is a frequent phenomenon during all disease stages, which possibly reflects α-synucleinopathy in the enteric nervous system. © 2016 John Wiley & Sons Ltd.

    Purpose: To develop a swallowing prediction system (SPS) using force sensing sensors and evaluate its feasibility. Methods: The SPS developed consists of force sensing sensor units, a thermoplastic mask, a signal transport device and a control PC installed with an in-house software. The SPS is designed to predict the pharyngeal stage of swallowing because it is known that internal organ movement occurs in pharyngeal stage. To detect prediction signal in the SPS, the force sensing sensor units were attached on both the submental muscle region and thyroid cartilage region of the thermoplastic mask. While the signal from the thyroid cartilage region informs the action of swallowing, the signal from the submental muscle region is utilized as a precursor for swallowing. Since the duration of swallowing is relatively short, using such precursor (or warning) signals for machine control is considered more beneficial. A volunteer study was conducted to evaluate the feasibility of the system. In this volunteer study, we intended to verify that the system could predict the pharyngeal stage of the swallowing. We measured time gaps between obtaining the warning signals in the SPS and starting points of the pharyngeal stage of swallowing. Results: The measured data was examined whether the time gaps were in reasonable order to be easily utilized. The mean and standard deviation values of these time gaps were 0.550 s ± 0.183 s. in 8 volunteers. Conclusion: The proposed method was able to predict the on-set of swallowing of human subjects inside the thermoplastic mask, which has never been possible with other monitoring systems such as camera-based monitoring system. With the prediction ability of swallowing incorporated into the machine control mechanism (in the future), beam delivery can be controlled to skip swallowing periods and significant dosimetric gain is expected in head & neck cancer treatments.

    The relation between infertility and sexual dysfunction can be reciprocal. Causes of sexual dysfunction that affect fertility include erectile dysfunction, Peyronie's disease (abnormal penile curvature), low libido, ejaculatory disorders in men, and genito-pelvic pain/penetration disorder (GPPPD) and low sexual desire in women. To review the association between infertility and sexual dysfunction and discuss current management strategies to address sexual disorders in couples with infertility. Peer-reviewed publications from PubMed published from 1980 through February 2016 were identified that related to sexual dysfunction and infertility in men and women. Pathophysiology and management approach of erectile dysfunction, Peyronie's disease, low libido, ejaculatory disorders in men, and GPPPD and low sexual desire in women and how each etiology contributes to sexual dysfunction and infertility in the couple. Treating the infertile couple with sexual dysfunction involves addressing underlying conditions such as psychogenic erectile dysfunction, low testosterone, Peyronie's disease in men, and GPPPD and low sexual desire in women. Psychogenic erectile dysfunction can be successfully treated with phosphodiesterase inhibitors. Low testosterone is often identified in men with infertility, but testosterone therapy is contraindicated in men attempting conception. Men with Peyronie's disease have a new treatment option to address their penile curvature-collagenase Clostridium histolyticum injection directly into the penile plaque. GPPPD is a broad disorder that includes vulvodynia and vaginismus and can be treated with topical lubricants and moisturizers. We must address psychosocial factors in women with low sexual desire. Flibanserin and transdermal testosterone (off-label) are novel therapies for women with low sexual desire. Sexual dysfunction in a couple with infertility is a complex issue. Management of infertility and sexual dysfunction should involve appropriate

    Background and purpose: Dysphagia is a serious complaint but frequently underreported. This paper assesses for oropharyngeal cancer (OPC) the relationship between the dose received by the swallowing structures, and the findings of a fiberoptic endoscopic evaluation of the swallowing process (FEES). Materials and methods: Between 2000 and 2005, 60 of 67 OPC patients local-regionally NED for at least one year following treatment responded to three types of QoL questionnaires; i.e. Performance Status Scales, EORTC H and N35, and M.D. Anderson Dysphagia Inventory. Twenty-four patients agreed to the FEES procedure. The main swallowing muscles were delineated, with the mean dose per muscle calculated using the original 3D CT-based treatment plans. Regression analysis was performed between FEES variables and the doses in the different swallowing muscles and the dysphagia related questionnaires. Results: A significant relationship was found between the results of FEES and the mean dose in the superior constrictor muscle (SCM). Some of the subjective dysphagia complaints were significantly correlated with the FEES variables in this retrospectively study. Conclusion: A higher dose in the SCM generally results in worsening of the findings obtained by the FEES examination

    Erectile dysfunction prevalence globally is noticeably high. This is accompanied by an increase in the use of nutraceuticals for male enhancement. However, the global market is invaded by counterfeit and adulterated nutraceuticals claimed to be of natural origin sold with a therapeutic claim. The objective of this article is to review male enhancement nutraceuticals worldwide with respect to claim, adulterants, and safety. The definition of such products is variable across countries. Thus, the registration procedures differ as well. This facilitates the manipulation of the process, which leads to widespread adulterated and counterfeit products without control. The tele-advertisement and Internet pharmacies aided the widespread sale of male enhancement nutraceuticals, unfortunately, the spurious ones. Finally, based on literature, most of these products were found to be adulterated with active pharmaceutical ingredients (API) and mislabeled as being natural. These products represent a major health hazard for consumers due to lack of clear regulations.

    Functional neuroimaging has shown that multiple brain regions are active during volitional swallowing. Little is known, however, about which regions integrate motor execution and sensory feedback in the swallowing system. Although unilateral brain lesions in either hemisphere can produce swallowing deficits, some functional neuroimaging studies indicate that the left hemisphere has greater activation in certain sensory and motor-related swallowing regions. In this study, correlation coefficients were computed for five seed regions during volitional saliva swallowing to determine the functional relationships of these regions with the rest of the brain: the anterior and posterior insula, inferior frontal gyrus (BA44), primary sensory cortex (S1), and primary motor cortex (M1). A laterality index (LI) was derived that accounts for relative differences in total, positive connected voxels for the left/right hemisphere seeds. Clusters of significantly connected voxels were greater from the anterior and posterior insula than from the other three seed regions. Interactions of the insula with other brain regions were greater on the left than on the right during volitional swallowing. Group means showed laterality in the anterior insula (LI = 0.25) and the posterior insula (LI = 0.33). BA44 showed a lesser degree of difference in left versus right hemisphere interactions (LI = 0.12) while S1 did not show lateralization (LI = 0.02) and M1 showed some predominance of interactions in the right hemisphere (LI = -0.19). The greater connectivity from the left hemisphere insula to brain regions within and across hemispheres suggests that the insula is a primary integrative region for volitional swallowing in humans.

    Characterization of the pharyngeal swallow response to volume challenges is important for swallowing function assessment. The diameter of the pressure-impedance recording catheter may influence these results. In this study, we captured key physiological swallow measures in response to bolus volume utilizing recordings acquired by two catheters of different diameter. Ten healthy adults underwent repeat investigations with 8- and 10-Fr catheters. Liquid bolus swallows of volumes 2.5, 5, 10, 20, and 30 mL were recorded. Measures indicative of distension, contractility, and flow timing were assessed. Pressure-impedance recordings with pressure-flow analysis were used to capture key distension, contractility, and pressure-flow timing parameters. Larger bolus volumes increased upper esophageal sphincter distension diameter (P < .001) and distension pressures within the hypopharynx and upper esophageal sphincter (P < .05). Bolus flow timing measures were longer, particularly latency of bolus propulsion ahead of the pharyngeal stripping wave (P < .001). Use of a larger-diameter catheter produced higher occlusive pressures, namely upper esophageal sphincter basal pressure (P < .005) and upper esophageal sphincter postdeglutitive pressure peak (P < .001). The bolus volume swallowed changed measurements indicative of distension pressure, luminal diameter, and pressure-flow timing; this is physiologically consistent with swallow modulation to accommodate larger, faster-flowing boluses. Additionally, catheter diameter predominantly affects lumen occlusive pressures. Appropriate physiological interpretation of the pressure-impedance recordings of pharyngeal swallowing requires consideration of the effects of volume and catheter diameter. NA.

    Videofluoroscopic swallow study (VFSS) is the gold standard for diagnosis of dysphagia in veterinary medicine but lacks standardized protocols that emulate physiologic feeding practices. Age impacts swallow function in humans but has not been evaluated by VFSS in dogs. To develop a protocol with custom kennels designed to allow free-feeding of 3 optimized formulations of contrast media and diets that address limitations of current VFSS protocols. We hypothesized that dogs evaluated by a free-feeding VFSS protocol would show differences in objective swallow metrics based on age. Healthy juvenile, adult, and geriatric dogs (n = 24). Prospective, experimental study. Custom kennels were developed to maintain natural feeding behaviors during VFSS. Three food consistencies (thin liquid, pureed food, and dry kibble) were formulated with either iohexol or barium to maximize palatability and voluntary prehension. Dogs were evaluated by 16 swallow metrics and compared across age groups. Development of a standardized VFSS protocol resulted in successful collection of swallow data in healthy dogs. No significant differences in swallow metrics were observed among age groups. Substantial variability was observed in healthy dogs when evaluated under these physiologic conditions. Features typically attributed to pathologic states, such as gastric reflux, were seen in healthy dogs. Development of a VFSS protocol that reflects natural feeding practices may allow emulation of physiology resulting in clinical signs of dysphagia. Age did not result in significant changes in swallow metrics, but additional studies are needed, particularly in light of substantial normal variation. Copyright © 2017 The Authors.

    There are heterogeneous subgroups among those with heartburn, and data on these individuals are relatively scant. We aimed to evaluate the effect of acid challenge on the segmental contractions of esophageal smooth muscle in endoscopy-negative patients with normal esophageal acid exposure. High-resolution esophageal manometry (HRM) was performed on 30 endoscopy-negative patients with heartburn accompanied by normal esophageal acid exposure using 10 water swallows followed by 10 acidic pomegranate juice swallows. Patients were classified into functional heartburn (FH) and hypersensitive esophagus (HE) groups based on the results of 24-hr impedance pH testing. HRM topographic plots were analyzed and maximal wave amplitude and pressure volumes were measured for proximal and distal smooth muscle segments. The pressure volume of the distal smooth muscle segment in the HE group measured during acidic swallows was higher than during water swallows (2224.1 ± 68.2 mmHg/cm per s versus 2105.6 ± 66.4 mmHg/cm per s, P = 0.027). A prominent shift in the pressure volume to the distal smooth muscle segment was observed in the HE group compared with the FH group (segmental ratio: 2.72 ± 0.08 versus 2.39 ± 0.07, P = 0.005). Manometric measurements during acidic swallows revealed that this shift was augmented in the HE group. The optimal ratio of pomegranate juice swallowing for discrimination of FH from HE was 2.82, with a sensitivity of 88.9% and a specificity of 100%. Hypercontractile response of distal smooth muscle segment to acid swallowing was more prominent in the HE group than the FH group. © 2012 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    Cannabinoids have been reported to be involved in affecting various biological functions through binding with cannabinoid receptors type 1 (CB1) and 2 (CB2). The present study was designed to investigate whether swallowing, an essential component of feeding behavior, is modulated after the administration of cannabinoid. The swallowing reflex evoked by the repetitive electrical stimulation of the superior laryngeal nerve in rats was recorded before and after the administration of the cannabinoid receptor agonist, WIN 55-212-2 (WIN), with or without CB1 or CB2 antagonist. The onset latency of the first swallow and the time intervals between swallows were analyzed. The onset latency and the intervals between swallows were shorter after the intravenous administration of WIN, and the strength of effect of WIN was dose-dependent. Although the intravenous administration of CB1 antagonist prior to intravenous administration of WIN blocked the effect of WIN, the administration of CB2 antagonist did not block the effect of WIN. The microinjection of the CB1 receptor antagonist directly into the nucleus tractus solitarius (NTS) prior to intravenous administration of WIN also blocked the effect of WIN. Immunofluorescence histochemistry was conducted to assess the co-localization of CB1 receptor immunoreactivity to glutamic acid decarboxylase 67 (GAD67) or glutamate in the NTS. CB1 receptor was co-localized more with GAD67 than glutamate in the NTS. These findings suggest that cannabinoids facilitate the swallowing reflex via CB1 receptors. Cannabinoids may attenuate the tonic inhibitory effect of GABA (gamma-aminobuteric acid) neurons in the central pattern generator for swallowing.

    Full Text Available Sexual activity is a multifaceted activity, involving complex interactions between the nervous system, the endocrine system, the vascular system and a variety of structures that are instrumental in sexual excitement, intercourse and satisfaction. Sexual function has three components i.e., desire, arousal and orgasm. Many sexual dysfunctions can be categorized according to the phase of sexual response that is affected. In actual clinical practice however, sexual desire, arousal and orgasmic difficulties more often than not coexist, suggesting an integration of phases. Sexual dysfunction can result from a wide variety of psychological and physiological causes including derangements in the levels of sex hormones and neurotrensmitters. This review deals with the biology of different phases of sexual function as well as implications of hormones and neurotransmitters in sexual dysfunction

    Innate and adaptive immune dysfunction, also referred to as cirrhosis-associated immune dysfunction syndrome, is a major component of cirrhosis, and plays a pivotal role in the pathogenesis of both the acute and chronic worsening of liver function. During the evolution of the disease, acute decompensation events associated with organ failure(s), so-called acute-on chronic liver failure, and chronic decompensation with progression of liver fibrosis and also development of disease specific complications, comprise distinct clinical entities with different immunopathology mechanisms. Enhanced bacterial translocation associated with systemic endotoxemia and increased occurrence of systemic bacterial infections have substantial impacts on both clinical situations. Acute and chronic exposure to bacteria and/or their products, however, can result in variable clinical consequences. The immune status of patients is not constant during the illness; consequently, alterations of the balance between pro- and anti-inflammatory processes result in very different dynamic courses. In this review we give a detailed overview of acquired immune dysfunction and its consequences for cirrhosis. We demonstrate the substantial influence of inherited innate immune dysfunction on acute and chronic inflammatory processes in cirrhosis caused by the pre-existing acquired immune dysfunction with limited compensatory mechanisms. Moreover, we highlight the current facts and future perspectives of how the assessment of immune dysfunction can assist clinicians in everyday practical decision-making when establishing treatment and care strategies for the patients with end-stage liver disease. Early and efficient recognition of inappropriate performance of the immune system is essential for overcoming complications, delaying progression and reducing mortality. PMID:24627592

  12. Nitric Oxide - Its Importance in Swallowing, Inflammatory Bowel Disease and Cirrhotic Cardiomyopathy

    Full Text Available Nitric oxide is a neurotransmitter found in the central and peripheral nervous systems. Nitric oxide synthase (NOS is localized in the central nervous system, including the nucleus of the solitary tract, nucleus ambiguus and dorsal motor nucleus of the vagus. These are regions that are implicated in the central control of swallowing and esophageal motility. In rats and rabbits, NOS has been shown to be present in the nucleus subcentralis of the nucleus of the solitary tract, and is thought to be responsible for the central programming of the striated muscle component of esophageal peristalsis. Beyak and co-workers from the University of Toronto, Toronto, Ontario provided evidence that the L-arginine-nitric oxide pathway is implicated in the central control of swallowing and esophageal motility. They studied oropharyngeal swallowing as well as esophageal peristalsis, and determined the functional role of brain stem nitric oxide by examining the effects of blockade of central nervous system NOS on swallowing, and on primary and secondary peristalsis. Administering NOS inhibitors intravenously or intracerebroventricularly into the fourth ventricle produced a number of oropharyngeal swallows and induced primary peristalsis in the smooth muscle portion of the esophageal body. NOS reduced the number of oropharyngeal swallows and the incidence of primary peristalsis in both smooth and striated muscle, and reduced the amplitude of peristalsis and smooth muscle contraction. This suggests that nitric oxide is a functional neurotransmitter in the central pattern generator responsible for swallowing and the central control of esophageal peristalsis. Peripherally administered NOS inhibitor can access structures within the blood-brain barrier to affect neuronal activity and physiological function. The central pattern generated for swallowing and esophageal peristalsis is suggested to be a serial network of linked neurons within the nucleus of the solitary

    Full Text Available Dália Nogueira,1 Elizabeth Reis21Speech Therapy Department, Escola Superior de Saúde de Alcoitão, Estoril, Portugal; 2Department of Quantitative Methods, Lisbon University Institute ISCTE/IUL, Lisbon, PortugalBackground: The swallowing mechanism changes significantly as people age, even in the absence of chronic diseases. Presbyphagia, a term that refers to aging-related changes in the swallowing mechanism, may be linked to many health conditions and presents itself in distinct ways. Swallowing disorders are also identified as a major problem amongst the elderly population living in nursing homes.Methods: The study sought to determine the prevalence of swallowing disorders in nursing home residents, to identify the relationship between self-perceived swallowing disorders, cognitive functions, autonomy, and depression, and also to analyze which variables explain the score of the Dysphagia Self-Test (DST. For this purpose, the researchers chose to apply a survey conveying questions on demographic aspects, general health, eating and feeding, as well as instruments to assess functional performance and the 3 ounce Water Swallow Test.Results: The sample consisted of 272 elderly people living in eight nursing homes in Portugal. Six did not sign the informed consent form. Of the total, 29% were totally dependent, 33% were depressed, 45% had cognitive impairment, and 38% needed help with feeding. About 43% of the individuals reported having problems related to eating. Regarding the DST, 40% showed signs of dysphagia. With respect to the 3 ounce Water Swallow Test, 38% revealed at least one of the symptoms, wet voice being the most prevalent. Correlation measures showed that age had no linear association with the DST score although correlation with the Barthel Index and Mini Mental State Examination was found to be significant. A linear regression model was estimated with the DST score as the dependent variable and the MMSE and BI scores, gender, age

    Palatal coverage is often required for elderly edentulous patients with complete dentures. The purpose of this study was to clarify impacts of palatal coverage on bolus formation and subsequent adaptive changes. Subjects were 18 healthy young dentulous adults who wore 1·5-mm-thick palatal plates. Subjects were asked to feed 12 g of bicoloured rice as usual, and the bolus formation by mastication and swallowing in the pharynx was observed using a nasal videoendoscopy. The bolus formation index (BFI), number of mastication strokes until swallowing, visual analogue scale about swallowing easiness and masticatory performance using colour-changeable gum were measured under three conditions: before placement of the palatal plate (day 0), immediately after placement (day 1) and after 7 days of wearing the plate (day 7). BFI and visual analogue scale on day 1 were significantly lower than those on day 0, but those on day 7 significantly recovered to the level of day 0. The number of mastication strokes did not change from day 0 to day 1, however, that on day 7 was significantly higher. Masticatory performance on days 1 and 7 was significantly lower than that on day 0. Although palatal coverage inhibits bolus formation during feeding, subjects increased the number of mastication strokes until swallowing threshold as they adapted to palatal coverage over time. This adaptive change was due to compensate for the lowered masticatory performance to achieve bolus formation for comfortable swallowing. © 2013 John Wiley & Sons Ltd.

    There have been results showing the influence of bolus viscosities and consistency on esophageal motility and transit. However, there is no description about the influence of two different viscous boluses on esophageal contractions, bolus transit and perception of transit. Our objective in this investigation was to evaluate the esophageal transit and contraction after swallows of two viscous boluses. By impedance and manometric methods, we measured the esophageal transit and contraction after swallows of two viscous boluses of 5 mL volume, 100% barium sulfate and yogurt, swallowed in duplicate in the supine and upright positions. The bolus transit, esophageal contractions and the perception of bolus transit through the esophagus were evaluated in both positions. Impedance and contraction were measured at 5, 10, 15 and 20 cm from the lower esophageal sphincter. After each swallow, the volunteers were asked about the sensation of bolus transit through the esophagus. In supine position, the yogurt had a less frequent complete bolus transit than barium. Also in the supine position, the esophageal transit was longer with yogurt than with barium. Esophageal contractions after swallows were similar between barium and yogurt boluses. There was no difference in perception of transit between the two boluses. Although both 100% barium sulfate and yogurt are viscous boluses and have similar viscosities, the transit through the esophagus is slower with yogurt bolus than with barium bolus, which suggests that viscosity may be not the sole factor to determine transit.

    Cliff swallows (Petrochelidon pyrrhonota) were inoculated with differing doses of West Nile virus (WNV) to evaluate their potential role as reservoir hosts in nature. Swallows often nest in large colonies in habitats and months associated with high mosquito abundance and early WNV transmission in North America. Additionally, cliff swallow diet consists of insects, including mosquitoes, leading to an additional potential route of WNV infection. The average peak viremia titer among infected cliff swallows was 106.3 plaque-forming units (PFU)/mL serum and the reservoir competence index was 0.34. There was no correlation between dose and probability of becoming infected or viremia peak and duration. Oral shedding was detected from 2 to 14 days post-inoculation with an average peak titer of 1044 PFU/swab. These results suggest that cliff swallows are competent reservoir hosts of WNV and therefore, they may play a role in early seasonal amplification and maintenance of WNV.

    Parkinson's disease (PD) has a high incidence in Mexico and is estimated at approximately 500,000 patients. One of the main clinical manifestations of PD is dysphagia, which is the difficult passage of food from the mouth to the stomach. The aim of this study was to assess oropharyngeal dysphagia through fibroendoscopy evaluation of swallowing in patients with PD. We conducted a census sample of patients with PD: 17 males and 10 females, aged >49 years. Clinical history, physical examination and neurological evaluation of swallowing fibroendoscopy were carried out. Of the symptomatic patients, 16 patients (59.25%) reported dysphagia. Fibroendoscopic evaluation demonstrated swallowing disorders in 25 patients (92.59%). The main findings were poor bolus control in 19 patients (70.37%), deficits in bolus propulsion in 25 patients (92.59%), impaired swallowing in 14 patients (51.85%), fractional swallowing in 11 patients (40.74%), reduced epiglottic tilting in 11 patients (48.14%), food residue in vallecula in 24 patients (88.88%) and piriform sinus in 19 patients (70.37%). There was no correlation between duration of PD and degree of involvement of oropharyngeal dysphagia. Oropharyngeal dysphagia in patients with PD is a common symptom and can range from the oral cavity to the upper esophageal sphincter. Early onset of severe dysphagia is exceptional in this disease and should alert the clinician to the diagnostic possibility of parkinsonism.

    Swallowing induces an inhibitory wave that is followed by a contractile wave along the esophageal body. Deglutitive inhibition in the skeletal muscle of the esophagus is controlled in the brain stem whilst in the smooth muscle, an intrinsic peripheral control mechanism is critical. The latency between swallow and contractions is determined by the pattern of activation of the inhibitory and excitatory vagal pathways, the regional gradients of inhibitory and excitatory myenteric nerves, and the intrinsic properties of the smooth muscle. A wave of inhibition precedes a swallow-induced peristaltic contraction in the smooth muscle part of the human oesophagus involving both circular and longitudinal muscles in a peristaltic fashion. Deglutitive inhibition is necessary for drinking liquids which requires multiple rapid swallows (MRS). During MRS the esophageal body remains inhibited until the last of the series of swallows and then a peristaltic contraction wave follows. A normal response to MRS requires indemnity of both inhibitory and excitatory mechanisms and esophageal muscle. MRS has recently been used to assess deglutitive inhibition in patients with esophageal motor disorders. Examples with impairment of deglutitive inhibition are achalasia of the LES and diffuse esophageal spasm.

    Full Text Available OBJECTIVE: To assess the routine use of barium swallow study in patients with chronic cough.METHODS: Between October of 2011 and March of 2012, 95 consecutive patients submitted to chest X-ray due to chronic cough (duration > 8 weeks were included in the study. For study purposes, additional images were obtained immediately after the oral administration of 5 mL of a 5% barium sulfate suspension. Two radiologists systematically evaluated all of the images in order to identify any pathological changes. Fisher's exact test and the chi-square test for categorical data were used in the comparisons.RESULTS: The images taken immediately after barium swallow revealed significant pathological conditions that were potentially related to chronic cough in 12 (12.6% of the 95 patients. These conditions, which included diaphragmatic hiatal hernia, esophageal neoplasm, achalasia, esophageal diverticulum, and abnormal esophageal dilatation, were not detected on the images taken without contrast. After appropriate treatment, the symptoms disappeared in 11 (91.6% of the patients, whereas the treatment was ineffective in 1 (8.4%. We observed no complications related to barium swallow, such as contrast aspiration.CONCLUSIONS: Barium swallow improved the detection of significant radiographic findings related to chronic cough in 11.5% of patients. These initial findings suggest that the routine use of barium swallow can significantly increase the sensitivity of chest X-rays in the detection of chronic cough-related etiologies.

    In spite of its importance, there have been few attempts to evaluate the sensory attributes of the food bolus during swallowing. In the current study, the slipperiness, the degree of slide for the food bolus through the mucosal surface of the oro-pharynx, and the compliance, how easily the shape of a food bolus can be transformed for automatic and comfortable swallowing, were derived among several sensory attributes related to the swallowing. Therefore, the study aims were twofold: (1) to develop the methods of sensory and instrumental analyses for determining the slipperiness and compliance of the food bolus during swallowing and (2) to examine the appropriateness of the newly designed devices by correlating the data between the sensory and instrumental analyses. Six commercial food products were evaluated by 10 trained panelists for each attribute. The devices for assessing each attribute were developed in consideration of the oro-pharyngeal movements. The sensory and instrumental analyses showed high correlation and regression coefficients as well as intensity differences of the 6 samples for each attribute. In conclusion, the slipperiness and the compliance were suitable for acquiring a better understanding of the sensory attributes of the food bolus during swallowing, and the newly developed devices showed a high potential for determining those attributes.

    We focused on brain areas activated by audiovisual stimuli related to swallowing motions. In this study, three kinds of stimuli related to human swallowing movement (auditory stimuli alone, visual stimuli alone, or audiovisual stimuli) were presented to the subjects, and activated brain areas were measured using functional MRI (fMRI) and analyzed. When auditory stimuli alone were presented, the supplementary motor area was activated. When visual stimuli alone were presented, the premotor and primary motor areas of the left and right hemispheres and prefrontal area of the left hemisphere were activated. When audiovisual stimuli were presented, the prefrontal and premotor areas of the left and right hemispheres were activated. Activation of Broca's area, which would have been characteristic of mirror neuron system activation on presentation of motion images, was not observed; however, activation of brain areas related to swallowing motion programming and performance was verified for auditory, visual and audiovisual stimuli related to swallowing motion. These results suggest that audiovisual stimuli related to swallowing motion could be applied to the treatment of patients with dysphagia. (author)

    Full Text Available The aim of this study was to assess the physiology of normal swallowing using recent advances in real-time magnetic resonance imaging (MRI. Therefore ten young healthy subjects underwent real-time MRI and flexible endoscopic evaluations of swallowing (FEES with thickened pineapple juice as oral contrast bolus. MRI movies were recorded in sagittal, coronal, and axial orientations during successive swallows at about 25 frames per second. Intermeasurement variation was analyzed and comparisons between real-time MRI and FEES were performed. Twelve distinct swallowing events could be quantified by real-time MRI (start time, end time, and duration. These included five valve functions: oro-velar opening, velo-pharyngeal closure, glottal closure, epiglottic retroflexion, and esophageal opening; three bolus transports: oro-velar transit, pharyngeal delay, pharyngeal transit; and four additional events: laryngeal ascent, laryngeal descent, vallecular, and piriform sinus filling and pharyngeal constriction. Repetitive measurements confirmed the general reliability of the MRI method with only two significant differences for the start times of the velo-pharyngeal closure (t(8=-2.4, P≤0.046 and laryngeal ascent (t(8=-2.6, P≤0.031. The duration of the velo-pharyngeal closure was significantly longer in real-time MRI compared to FEES (t(8=-3.3, P≤0.011. Real-time MRI emerges as a simple, robust, and reliable tool for obtaining comprehensive functional and anatomical information about the swallowing process.

    Cardiovascular dysfunction may be defined as the inability of any element of the cardiovascular system to perform adequately upon demand, leading to inadequate performance and nutritive insufficiency of various parts of the body. Exposure to supralethal doses of radiation (accidental and therapeutic) has been show to induce significant alterations in cardiovascular function in man. These findings indicate that, after irradiation, cardiovascular function is a major determinant of continued performance and even survival. For the two persons who received massive radiation doses (45 and 88 Gy, respectively) in criticality accidents, the inability to maintain systematic arterial blood pressure (AP) was the immediate cause of death. In a study of cancer patients given partial-body irradiation, two acute lethalities were attributed to myocardial infarction after an acute hypotensive episode during the first few hours postexposure. Although radiation-induced cardiovascular dysfunction has been observed in many species, its severity, duration, and even etiology may vary with the species, level of exposure, and dose rate. For this reason, our consideration of the effects of radiation on cardiovascular performance is limited to the circulatory derangements that occur in rat, dog, and monkey after supralethal doses and lead to radiation-induced cardiovascular dysfunction in these experimental models. The authors consider other recent data as they pertain to the etiology of cardiovascular dysfunction in irradiated animals

  10. Advances in sepsis-associated liver dysfunction

    Dawei Wang

    2014-07-01

    Full Text Available Recent studies have revealed liver dysfunction as an early event in sepsis. Sepsis-associated liver dysfunction is mainly resulted from systemic or microcirculatory disturbances, spillovers of bacteria and endotoxin (lipopolysaccharide, LPS, and subsequent activation of inflammatory cytokines as well as mediators. Three main cell types of the liver which contribute to the hepatic response in sepsis are Kupffer cells (KCs, hepatocytes and liver sinusoidal endothelial cells (LSECs. In addition, activated neutrophils, which are also recruited to the liver and produce potentially destructive enzymes and oxygen-free radicals, may further enhance acute liver injury. The clinical manifestations of sepsis-associated liver dysfunction can roughly be divided into two categories: Hypoxic hepatitis and jaundice. The latter is much more frequent in the context of sepsis. Hepatic failure is traditionally considered as a late manifestation of sepsis-induced multiple organ dysfunction syndrome. To date, no specific therapeutics for sepsis-associated liver dysfunction are available. Treatment measure is mainly focused on eradication of the underlying infection and management for severe sepsis. A better understanding of the pathophysiology of liver response in sepsis may lead to further increase in survival rates.

    Chronic poststroke oropharyngeal dysfunction (OD) is a common condition, leading to severe complications, including death. Treatments for chronic poststroke OD are scarce. The aim of our study was to assess and compare the efficacy and safety of treatment with surface electrical stimulation (e-stim) at sensory and motor intensities in patients with chronic poststroke OD. Twenty chronic poststroke patients with OD were randomly assigned to (i) sensory e-stim (treatment intensity: 75% of motor threshold) or (ii) motor e-stim (treatment intensity: motor threshold). Patients were treated during 10 days, 1 h/day. Videofluoroscopy was performed at the beginning and end of the study to assess signs of impaired efficacy and safety of swallow and timing of swallow response. Patients presented advanced age (74.95 ± 2.18), 75% were men. The mean days poststroke was 336.26 ± 89.6. After sensory stimulation, the number of unsafe swallows was reduced by 66.7% (p swallows was reduced by 62.5% (p = 0.002), the laryngeal vestibule closure time by 38.26% (p = 0.009) and maximal vertical hyoid extension time by 24.8% (p = 0.008). Moreover, the motor stimulus reduced the pharyngeal residue by 66.7% (p = 0.002), the upper esophageal sphincter opening time by 39.39% (p = 0.009), and increased bolus propulsion force by 211.1% (p = 0.008). No serious adverse events were detected during the treatment. Surface e-stim is a safe and effective treatment for chronic poststroke dysphagic patients. © 2013 John Wiley & Sons Ltd.

    Full Text Available In addition to urinary incontinence and erectile dysfunction, several other impairments of sexual function potentially occurring after radical prostatectomy (RP have been described; as a whole, these less frequently assessed disorders are referred to as neglected side effects. In particular, orgasmic dysfunctions (ODs have been reported in a non-negligible number of cases, with detrimental impacts on patients’ overall sexual life. This review aimed to comprehensively discuss the prevalence and physiopathology of post-RP ODs, as well as potential treatment options. Orgasm-associated incontinence (climacturia has been reported to occur in between 20% and 93% of patients after RP. Similarly, up to 19% of patients complain of postoperative orgasm-associated pain, mainly referred pain at the level of the penis. Moreover, impairment in the sensation of orgasm or even complete anorgasmia has been reported in 33% to 77% of patients after surgery. Clinical and surgical factors including age, the use of a nerve-sparing technique, and robotic surgery have been variably associated with the risk of ODs after RP, although robust and reliable data allowing for a proper estimation of the risk of postoperative orgasmic function impairment are still lacking. Likewise, little evidence regarding the management of postoperative ODs is currently available. In general, physicians should be aware of the prevalence of ODs after RP, in order to properly counsel all patients both preoperatively and immediately post-RP about the potential occurrence of bothersome and distressful changes in their overall sexual function.

    Full Text Available Some children with epilepsy display a low level of intelligence, learning disabilities, attention deficit hyperactivity disorder, mood disorders and anxiety. Besides specific learning disabilities like reading, writing, arithmetics, learning problems may involve other major areas of intellectual functions such as speech and language, attention, memory, fine motor coordination. Even in the presence of common pathology that leads to epilepsy and mental dysfunctions, seizures cause additional cognitive problems. Age at seizure onset, type of seizures and epileptic syndromes are some variables that determine the effect of epilepsy on cognition. As recurrent seizures may have some negative impact on the developing brain, the use of antiepileptic drugs should be considered not only to aim reducing seizures but also to prevent possible seizure-induced cortical dysfunctions. Epilepsy is a disorder requiring a complicated psychological adjustment for the patients and indeed is a disease that affects the whole family. Thus, the management of epilepsy must include educational, psychotherapeutic and behavioral interventions as well as drug treatment.

    Fifty one infants and older children with suspected gastro-oesophageal reflux entered a study comparing the diagnostic accuracy of a standard barium swallow examination with that of ultrasound scanning. All children were examined by both techniques. In 40 cases there was unequivocal agreement between the examinations. Of the remaining patients, four had definite reflux by ultrasonic criteria but showed no evidence of reflux on barium swallow examination, four had positive findings on ultrasound but showed only minimal reflux on barium swallow, and one showed minimal reflux on ultrasound but had a negative barium meal result. In two children the ultrasound study was inconclusive. Ultrasound has an important role in the diagnosis and follow up of patients under the age of 5 years with gastro-oesophageal reflux.

    Dysphagia is a medical condition that can lead to devastating complications including weight loss, aspiration pneumonia, dehydration, and malnutrition; hence, timely identification is essential. Current dysphagia evaluation tools are either invasive, time consuming, or highly dependent on the experience of an individual clinician. The present study aims to develop a non-invasive, quantitative screening tool for dysphagia identification by capturing acoustic data from swallowing and mastication. The first part of this study explores the feasibility of using acoustic data to quantify swallowing and mastication. This study then further identifies mastication and swallowing trends in a neurotypical adult population. An acoustic capture protocol for dysphagia screening is proposed. Finally, the relationship among speaking, lingual and mastication rates are explored. Results and future directions are discussed.

    Video fluoroscopic examination of swallowing generally needs a contrast media such as a barium sulfate. Since the examination is usually performed in patients with dysphasia, there is a risk of aspiration. We tried to visualize the laryngopharynx during swallowing of negative contrast media (air) with 64-row multi-detector computed tomography (64-MDCT). Cine mode 64-MDCT was performed to visualize the laryngopharynx in 4 healthy volunteers during swallowing of negative contrast media (air). The data were converted to three-dimensional (3D) images of 2 conditions (air and bone) and sagittal images of the soft tissue condition at a workstation. These images were sent to a personal computer and modeled to 3D cine images with Digital Imaging and Communication in Medicine (DICOM) Viewer and Quick Time Player. 3D cine images demonstrated movements of the epiglottis, vallecula, piriform sinus, tongue, pharyngeal wall, hyoid bone and thyroid cartilage.

    Clinics often encounter neurologically intact patients who are unable to swallow pills. All of the interventions published previously have used traditional behavioural techniques, which are time consuming and often not helpful. To determine whether children who had never been able to swallow a whole pill could become successful as a result of an intervention based on head posture. A novel intervention was developed based on published research showing that changing head position alters swallowing dynamics. The method was developed in two studies of 240 adults and children, pilot tested in a study of 108 university students with very mild pill-swallowing discomfort, and then evaluated in a study of 41 children who had never successfully swallowed a pill in spite of much instruction and coaxing. Children were recruited from a tertiary paediatric hospital: 34 were clinic patients, four were their siblings or friends, and three were children of hospital staff. The primary intervention involved teaching five head positions (centre, up, down, left and right) followed by a two-week period of daily practice. EIGHT CHILDREN (ALL CLINIC REFERRALS) WITHDREW WITHOUT PRACTICING: four were too ill to practice (primarily due to sedation or nausea) and four simply refused to do the homework practice. All 33 of the children who were able and willing to practice daily were successful. Practice with head posture variations was successful in treating pill-swallowing difficulties in all 33 children who practiced for 14 days.

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

    This study investigated the impact of radiotherapy on swallowing function in 152 patients with esophageal cancer. Swallowing function was retrospectively assessed in these patients using a swallowing-function scoring system. Total tumor dose ranged from 22.5 Gy in 14 fractions to 104.4 Gy in 50 fractions. Improvement in dysphagia was noted in 62.3% of these patients, with a median time to improvement of 6 weeks. Improvement rate of patients irradiated with 20.0 to 34.9 Gy, 35.0 to 59.9 Gy and 60.0 Gy or more was 23.1%, 58.3% and 71.6%, respectively. Patients with T1-3 showed, a greater improvement rate than patients with T4 cancer (72.2% versus 54.1%). On multivariate analysis, the initial score, total dose and T factor correlated with improvements in swallowing function. Our results suggest that 35.0 Gy or more is necessary to improve swallowing function. The median duration in which patients could swallow soft or solid foods, was 8 months in patients receiving 60.0 Gy or more and 2 months in patients receiving 50.0 to 59.9 Gy, respectively. There was a significant difference between these periods (p<0.01). Regarding duration of palliation, median duration for patients receiving 60.0 Gy or more was 30 weeks, while it was 22 weeks for patients treated with lesser doses (p=0.053). We recommend 60.0 Gy or more as the optimal dosage for improving dysphagia. (author)

    A methodology of studying of ingestive behavior by non-invasive monitoring of swallowing (deglutition) and chewing (mastication) has been developed. The target application for the developed methodology is to study the behavioral patterns of food consumption and producing volumetric and weight estimates of energy intake. Monitoring is non-invasive based on detecting swallowing by a sound sensor located over laryngopharynx or by a bone-conduction microphone and detecting chewing through a below-the-ear strain sensor. Proposed sensors may be implemented in a wearable monitoring device, thus enabling monitoring of ingestive behavior in free-living individuals. In this paper, the goals in the development of this methodology are two-fold. First, a system comprising sensors, related hardware and software for multi-modal data capture is designed for data collection in a controlled environment. Second, a protocol is developed for manual scoring of chewing and swallowing for use as a gold standard. The multi-modal data capture was tested by measuring chewing and swallowing in 21 volunteers during periods of food intake and quiet sitting (no food intake). Video footage and sensor signals were manually scored by trained raters. Inter-rater reliability study for three raters conducted on the sample set of five subjects resulted in high average intra-class correlation coefficients of 0.996 for bites, 0.988 for chews and 0.98 for swallows. The collected sensor signals and the resulting manual scores will be used in future research as a gold standard for further assessment of sensor design, development of automatic pattern recognition routines and study of the relationship between swallowing/chewing and ingestive behavior

    Although it is known that dysphagia contributes to significant malnutrition, pneumonia, and mortality in amyotrophic lateral sclerosis (ALS), it remains unclear how swallowing impairment impacts quality of life in this vulnerable patient population. The aim of the current study was to (1) delineate swallow-related quality of life (SR-QOL) profiles in individuals with ALS and (2) evaluate relationships between SR-QOL, degree of swallowing impairment, and ALS global disease progression. Eighty-one ALS patients underwent a standardized videofluoroscopic swallow study and completed the swallowing quality of life (SWAL-QOL) instrument and ALS functional rating scale-revised (ALSFRS-R). Penetration Aspiration Scale (PAS) scores were derived by a blinded rater. Correlation analyses and a between groups ANOVA (safe vs. penetrators vs. aspirators) were performed. Mean SWAL-QOL score for this cohort was 75.94 indicating a moderate degree of SR-QOL impairment with fatigue, eating duration, and communication representing the most affected domains. Correlations were revealed between the SWAL-QOL and (1) PAS (r = −0.39, p < 0.001) and (2) ALSFRS-R (r = 0.23, p < 0.05). Mean (SD) SWAL-QOL scores for safe versus penetrator versus aspirator groups were 81.2 (2.3) versus 77 (3.4) versus 58.7 (5.9), respectively, with a main effect observed [F(2,78) = 9.71, p < 0.001]. Post hoc testing revealed lower SWAL-QOL scores for aspirators versus safe swallowers (p < 0.001) and aspirators versus penetrators (p < 0.001). Overall, SR-QOL was moderately reduced in this cohort of ALS patients and profoundly impacted in ALS aspirators and individuals with advanced disease. These findings highlight the importance of early multidisciplinary intervention to not only avoid malnutrition, weight loss, and pulmonary sequelae but also the associated reduced QOL seen in these individuals.

    Evaluation of treatment outcome is important in maxillofacial rehabilitation. Although eating is one of the oral functions that most strongly influences patients' quality of life, only a few reports exist on the objective assessment of swallowing for maxillectomy patients. The purpose of this study was to identify changes in the swallowing ability of maxillectomy patients when wearing obturator prostheses through the use of an objective clinical assessment. The swallowing ability of 38 postmaxillectomy patients consecutively treated with obturator prostheses was objectively evaluated with the "water-drinking test" that was developed for the assessment of dysphagia patients after cerebrovascular disease. In this test, the subjects were instructed to drink 30 mL of water in one swallow. The profile was evaluated with the combination of the time required for drinking the water and the incidence of cough reflex. Statistical analysis was performed using the Wilcoxon signed-rank test, the paired t test, and the Chi-square test with StatView 5.0 for the Macintosh. Performance improved significantly when the patients wore prostheses (P = .0026, Wilcoxon signed-rank test). The mean drinking times without and with prostheses were 8.2 +/- 6.3 s and 5.0 +/- 3.5 s, respectively. Drinking time was shortened significantly when the prosthesis was worn (P = .0002, paired t test). The assessment of behavior and episodes revealed that the swallowing ability of the maxillectomy patients was significantly improved when a prosthesis was worn (P = .0002, Chi-square test). The swallowing ability of maxillectomy patients was quantitatively and qualitatively improved with obturator prostheses.

    In this study, we evaluated the swallowing function with surface electromyography before and after tonsillectomy. Twenty patients (12 males, 8 females; mean age 23.8 years; range 17 to 30 years) who had tonsillectomy indication as study group, and 10 healthy individuals (8 males, 2 females; mean age 26 years; range 18 to 35 years) as control group were included in this prospective study between October 2008 and February 2009. Due to their significant role on oral and faringeal phases of swallowing; the surface electromyography prosedure is performed on the masseter muscle, the submental-submandibular muscle group and the infrahyoid muscles to measure their electrical activity and duration of contraction. For this purpose, single swallow and continuous drinking of 100 cc water tests were applied to each patient preoperatively and; in the postoperative 1st week and the 1st month. The preoperative duration of drinking periods were significanly longer in the study group compared to the control group (p<0.05). At the end of the first postoperative week the duration of drinking 100 cc water test was significantly longer than the preoperative mean of the study group (p<0.05). After one month single- swallow durations of study group were significantly shorter then the preoperative mean (p<0.05). The electrical activity of the masseter and infrahyoid muscles were significantly higher in study group compared with control group (p<0.05). The close proximity of the surgical area to the muscles affects swallowing after tonsillectomy. The surface electromyography is a simple, non-invasive and reliable method for postoperative evaluation of the swallowing functions of the throat muscles and thereby allows monitoring of the recovery and functional improvement of these muscles.
