RESUMO
BACKGROUND: Diagnosing dysphagia in acute stroke patients is crucial, as this comorbidity determines morbidity and mortality; we therefore investigated the impact of flexible nasolaryngeal endoscopy (FEES) in acute stroke patients. METHODS: The FEES investigation as performed in acute stroke patients treated at a large university hospital, allocated as a standard procedure for all patients suspected of dysphagia. We correlated our findings with baseline data, disability status, pneumonia, duration of hospitalisation, necessity for mechanical ventilation and treatment on the intensive care unit. The study was designed as a cross-sectional hospital-based registry. RESULTS: We investigated 152 patients. The median age was 73; 94 were male. Ischemic stroke was diagnosed in 125 patients (82.2%); 27 (17.8%) suffered intracerebral haemorrhage. Oropharyngeal dysphagia was diagnosed in 72.4% of the patients, and was associated with higher stroke severity on admission (median NIHSS 11 [IQR 6-17] vs. 7 [4-12], p = .013; median mRS 5 [IQR 4-5] vs. 4 [IQR 3-5], p = .012). Short-term mortality was higher among patients diagnosed with dysphagia (7.2% vs. 0%, p = .107). FEES examinations revealed that only 30.9% of the patients had an oral diet appropriate for their swallowing abilities. A change of oral diet was associated with a better outcome at discharge (mRS; p = .006), less need of mechanical ventilation (p = .028), shorter period of hospitalisation (p = .044), and lower rates of pneumonia (p = .007) and mortality (p = .011). CONCLUSION: Due to the inability of clinical assessments to detect silent aspiration, FEES might be better suited to identify stroke patients at risk and may contribute to a better functional outcome and lower rates of pneumonia and mortality. Our findings also point to a low awareness of dysphagia, even in a specialised stroke centre. FEES in acute stroke patients helps to adjust the oral diet for the vast majority of stroke patients (69.1%) based on their swallowing abilities, potentially avoiding severe complications.

BACKGROUND: Neurogenic dysphagia is one of the most frequent and prognostically relevant neurological deficits in a variety of disorders, such as stroke, parkinsonism and advanced neuromuscular diseases. Flexible endoscopic evaluation of swallowing (FEES) is now probably the most frequently used tool for objective dysphagia assessment in Germany. It allows evaluation of the efficacy and safety of swallowing, determination of appropriate feeding strategies and assessment of the efficacy of different swallowing manoeuvres. The literature furthermore indicates that FEES is a safe and well-tolerated procedure. In spite of the huge demand for qualified dysphagia diagnostics in neurology, a systematic FEES education has not yet been established. RESULTS: The structured training curriculum presented in this article aims to close this gap and intends to enforce a robust and qualified FEES service. As management of neurogenic dysphagia is not confined to neurologists, this educational programme is applicable to other clinicians and speech-language therapists with expertise in dysphagia as well. CONCLUSION: The systematic education in carrying out FEES across a variety of different professions proposed by this curriculum will help to spread this instrumental approach and to improve dysphagia management.

BACKGROUND: Stroke is the most frequent cause of neurogenic oropharyngeal dysphagia (NOD). In the acute phase of stroke, the frequency of NOD is greater than 50% and, half of this patient population return to good swallowing within 14 days while the other half develop chronic dysphagia. Because dysphagia leads to aspiration pneumonia, malnutrition, and in-hospital mortality, it is important to pay attention to swallowing problems. The question arises if a prediction of severe chronic dysphagia is possible within the first 72 hours of acute stroke. METHODS: On admission to the stroke unit, all stroke patients were screened for swallowing problems by the nursing staff within 2 hours. Patients showing signs of aspiration were included in the study (n = 114) and were given a clinical swallowing examination (CSE) by the swallowing/speech therapist within 24 hours and a swallowing endoscopy within 72 hours by the physician. The primary outcome of the study was the functional communication measure (FCM) of swallowing (score 1-3, tube feeding dependency) on day 90. RESULTS: The grading system with the FCM swallowing and the penetration-aspiration scale (PAS) in the first 72 hours was tested in a multivariate analysis for its predictive value for tube feeding-dependency on day 90. For the FCM level 1 to 3 (P < .0022) and PAS level 5 to 8 (P < .00001), the area under the curve (AUC) was 72.8% and showed an odds ratio of 11.8 (P < .00001; 95% confidence interval 0.036-0.096), achieving for the patient a 12 times less chance of being orally fed on day 90 and therefore still being tube feeding-dependent. CONCLUSIONS: We conclude that signs of aspiration in the first 72 hours of acute stroke can predict severe swallowing problems on day 90. Consequently, patients should be tested on admission to a stroke unit and evaluated with established dysphagia scales to prevent aspiration pneumonia and malnutrition. A dysphagia program can lead to better communication within the stroke unit team to initiate the appropriate diagnostics and swallowing therapy as soon as possible.

Oropharyngeal sensitivity plays a vital role in the initiation of the swallowing reflex and is thought to decline as part of the aging-process. Taste and smell functions appear to decline with age as well. The aim of our study was to generate data of oral sensitivity in healthy participants for future studies and to analyse age-related changes and their interdependence by measuring oral sensitivity, taste, and smell function. The experiment involved 30 participants younger than and 30 participants older than 60. Sensitivity threshold as a surrogate of oral sensitivity was measured at the anterior faucial pillar by electrical stimulation using commercially available pudendal electrode mounted on a gloved finger. Smell and taste were evaluated using commercially available test kits. Mean sensitivity was lower in young participants compared to older participants (1.9 ± 0.59 mA vs. 2.42 ± 1.03 mA; p = 0.021). Young participants also performed better in smell (Score 11.13 ± 0.86 vs 9.3 ± 1.93; p < 0.001) and taste examinations (Score 11.83 ± 1.86 vs 8.53 ± 3.18; p < 0.001). ANCOVA revealed a statistical association between sensitivity and smell (p = 0.08) that was moderated by age (p = 0.044). Electrical threshold testing at the anterior faucial pillar is a simple, safe, and accurate diagnostic measure of oral sensitivity. We detected a decline of oral sensitivity, taste, and smell in older adults.Trial registration: Clinicaltrials.gov, NCT03240965.

OlfatoRESUMO
PURPOSE: Dysphagia is common in critically ill neurological patients and is associated with a high mortality and morbidity. Data on the usefulness of flexible endoscopic examination of swallowing (FEES) in neurological intensive care unit (ICU) patients are lacking, raising the need for evaluation. METHOD: FEES was performed in neurological intensive care patients suspected of dysphagia. We correlated findings with baseline data, disability status, pneumonia and duration of hospitalisation, as well as a need for mechanical ventilation or tracheotomy. RESULT: This analysis consisted of 125 patients with suspected dysphagia. Most of the patients (81; 64,8%) suffered from acute stroke. Dysphagia was diagnosed using FEES in 90 patients (72%). FEES results led to dietary modifications in 80 patients (64%). The outcome at discharge was worse in dysphagic stroke patients diagnosed by FEES as compared to non-dysphagic stroke patients (p = 0.009). Patients without oral diet had higher need for intubation (p = 0.007), tracheotomy (p = 0.032) and higher mortality (p < 0.001) in comparison to patients with at least small amounts of oral intake. CONCLUSION: As the clinical assessment of the patients often classified the dysphagia incorrectly, the broad use of FEES in ICU patients might help to adequately adjust patients' oral diet. This knowledge might contribute to lower mortality and morbidity.

Dysphagia is common in neurological disease. However, our understanding of swallowing and its central nervous control is limited. Sensory information plays a vital role in the initiation of the swallowing reflex and is often reduced in stroke patients. We hypothesized that the sensitivity threshold of the anterior faucial pillar could be facilitated by either electrical stimulation (ES) or taste and smell information. The sensitivity threshold was measured by ES in the anterior faucial pillar region. The measurement was repeated 5 min after baseline. Thirty minutes after baseline, the participants underwent a test for taste and smell. Immediately after the test, the ES was repeated. Thirty healthy volunteers with a mean age of 27 ± 5.1 participated in the trial. Mean sensitivity threshold at baseline was 1.9 ± 0.59 mA. The values 5 min after baseline (1.74 ± 0.56 mA, p = 0.027) and 30 min after baseline (1.67 ± 0.58 mA, p = 0.011) were significantly lower compared to the baseline, but there was no difference between the latter (p = 0.321). After 5 min, a potentially facilitating effect was found on oral sensitivity by ES of the faucial pillar area. Thirty minutes later, this effect was still present.Trial registration Clinicaltrials.gov, NCT03240965. Registered 7th August 2017- https://clinicaltrials.gov/ct2/show/NCT03240965 .

We describe a patient who suddenly developed dysphagia for liquids as the sole manifestation of stroke. Magnetic resonance imaging (MRI) revealed a right-sided infarction of the superior part of the anterior insula and a small portion of the adjacent medial frontal operculum. These findings confirm the role of the anterior insula as a critical area in humans with regard to the origin of dysphagia.

Amyotrophic lateral sclerosis (ALS) is the most common neurodegenerative disease of the motor system. Bulbar symptoms such as dysphagia and dysarthria are frequent features of ALS and can result in reductions in life expectancy and quality of life. These dysfunctions are assessed by clinical examination and by use of instrumented methods such as fiberendoscopic evaluation of swallowing and videofluoroscopy. Laryngospasm, another well-known complication of ALS, commonly comes to light during intubation and extubation procedures in patients undergoing surgery. Laryngeal and pharyngeal complications are treated by use of an array of measures, including body positioning, compensatory techniques, voice and breathing exercises, communication devices, dietary modifications, various safety strategies, and neuropsychological assistance. Meticulous monitoring of clinical symptoms and close cooperation within a multidisciplinary team (physicians, speech and language therapists, occupational therapists, dietitians, caregivers, the patients and their relatives) are vital.

OBJECTIVES: Fibre-endoscopic evaluation of swallowing (FEES) to detect dysphagia is gaining more and more importance as a diagnostic tool. Therefore, we have investigated the impact of FEES in neurological patients in a clinical setting. DESIGN: Cross-sectional hospital-based registry. SETTING: Primary acute care in a neurological department of a German university hospital. PARTICIPANTS: 241patients with various neurological diseases who underwent FEES procedure. PRIMARY AND SECONDARY OUTCOME MEASURES: Dysphagia and related comorbidities. RESULTS: 267 FEES were performed in 241 patients with various neurological diagnoses. Dysphagia was diagnosed in 68.9% of the patients. In only 33.1% of the patients, appropriate oral diet was chosen prior to FEES. A relevant dysphagia occurred more often in patients with structural brain lesions (83.1% vs 65.3%, P=0.001), patients with dysphagia had a longer hospitalisation (median 18 (IQR 12-30) vs 15 days (IQR 9.75-22.75), P=0.005) and had a higher mortality (8.4% vs 1.3%, P=0.041). When the oral diet was changed, we observed a lower pneumonia rate (36% vs 50%, P=0.051) and a lower mortality (3.7% vs 11.3%, P=0.043) in comparison to no change of oral diet. A restriction of oral diet was identified more often in older patients (median 75 years (IQR 66.3-82 years) vs median 72 years (IQR 60-79 years), P=0.01) and in patients with structural brain lesions (86.8% vs 73.1%, P=0.05). CONCLUSION: On clinical investigation, dysphagia was misjudged for the majority of the patients. FEES might help to compensate this drawback, revising the diet regime in nearly 70% of the patients.

AIMS: There is behavioral evidence of increased spontaneous recruitment of visual attention to ancestral evolved categories, such as animals, compared with expertise-derived categories, such as a computer. In order to investigate the association between visual perception and spontaneous visual attention, a study was performed to determine if brain activation whilst viewing moving animals was increased compared with optokinetic computer stimuli. METHODS: Functional MRI was performed in 12 healthy volunteers using a standard block-design paradigm, consisting of three consecutive experiments. Subjects viewed the following images: Experiment one--optokinetic computer stimuli alternating with static computer stimuli; Experiment two--moving animals alternating with non-moving animals; Experiment three--moving animals alternating with optokinetic computer stimuli. RESULTS: Moving animals evoked motion-dependent activation bilaterally in the middle and superior temporal gyri, right inferior temporal gyrus, left occipital gyrus, right supramarginal gyrus, and left straight gyrus. Integrated object-and-motion-dependent activation was found bilateral in inferior and middle temporal gyri, right superior temporal gyrus, right superior parietal lobule, left dorsal putamen, and right amygdala. CONCLUSIONS: These results suggest that there is increased cerebral activity in the visuo-attentional network whilst viewing moving animals compared with optokinetic computer stimuli.

BACKGROUND AND PURPOSE: The World Health Organization's International Classification of Functioning, Disability and Health (ICF) is gaining recognition in physical therapy. The Extended ICF Core Set for Stroke is a practical tool that represents a selection of categories from the whole classification and can be used along with the ICF qualifier scale to describe patients' functioning and disability following stroke. The application of the ICF qualifier scale poses the question of interrater reliability. The primary objective of this investigation was to study the agreement between physical therapists' ratings of subjects' functioning and disability with the Extended ICF Core Set for Stroke and with the ICF qualifier scale. Further objectives were to explore the relationships between agreement and rater confidence and between agreement and physical therapists' areas of core competence. SUBJECTS AND METHODS: A monocentric, cross-sectional reliability study was conducted. A consecutive sample of 30 subjects after stroke participated. Two physical therapists rated the subjects' functioning in 166 ICF categories. RESULTS: The interrater agreement of the 2 physical therapists was moderate across all judgments (observed agreement=51%, kappa=.41). Interrater reliability was not related to rater confidence or to the physical therapists' areas of core competence. DISCUSSION AND CONCLUSION: The present study suggests potential improvements to enhance the implementation of the ICF and the Extended ICF Core Set for Stroke in practice. The results hint at the importance of the operationalization of the ICF categories and the standardization of the rating process, which might be useful in controlling for rater effects and increasing reliability.
