Rotigotine Transdermal Patch Improves Swallowing in Dysphagic Patients with Parkinson’s Disease
Abstract Abnormal swallowing, dysphagia, is a potentially fatal symptom in Parkinson’s disease (PD) and is characterized by frequent silent aspiration, an unrecognized risk of suffocation and aspiration pneumonia. Several studies have reported that the injection of apomorphine, a dopamine agonist, alleviated dysphagia in some patients with PD. The effects of other antiparkinson medications against dysphagia remain controversial. Rotigotine is another dopamine agonist with non-oral administration, i.e., a transdermal patch. Its noninvasiveness seems to render this medicine even more suitable than apomorphine ...

Penetration–Aspiration: Is Their Detection in FEES ® Reliable Without Video Recording?
Abstract Penetration–aspiration is known as the main finding in deglutition-disordered patients with implications for diagnostics and therapeutic management. Reliable detection of penetration–aspiration is given with fiberoptic endoscopic evaluation of swallowing (FEES®) as one of the gold standards in instrumental swallowing evaluation. The advice to implement video recording in FEES® to assure quality in identifying penetration–aspiration is often ignored, especially in bed-side settings. Thus, the aim of this study was to compare reliability and validity in detecting penetration–...

Electromagnetic Sensor-Guided Enteral Access Systems: A Literature Review
Abstract Enteral feeding is the nutritional support of choice for acutely ill patients with functional gastrointestinal tracts who are unable to swallow. Several benefits including reduced mortality and length of hospital stay have been associated with early initiation of enteral feeding. However, misplacement of conventional nasoenteric tubes is relatively common and can result in complications including pneumothorax. In addition, the need to confirm the position by X-ray can delay the start of using the tube. Eliminating these delays can help patients start feeding, and minimise the adverse impact on initiating ...

The Relationship Between Pharyngeal Constriction and Post-swallow Residue
Abstract Pharyngeal constriction has been proposed as a parameter that may distinguish functional from impaired swallows. We employed anatomically normalized pixel-based measures of pharyngeal area at maximum constriction, and the ratio of this measure to area at rest, and explored the association between these measures and post-swallow residue using the normalized residue ratio scale (NRRS). Videofluoroscopy data for 5 ml boluses of 22 % (w/v) liquid barium were analyzed from 20 healthy young adults and 40 patients with suspected neurogenic dysphagia. The frames of maximum pharyngeal constriction and po...

Effects of Strengthening Exercises on Swallowing Musculature and Function in Senior Healthy Subjects: a Prospective Effectiveness and Feasibility Study
Abstract Head and neck cancer (HNC) patients may develop dysphagia due to muscle atrophy and fibrosis following chemoradiotherapy. Strengthening of the swallowing muscles through therapeutic exercise is potentially effective for improving swallowing function. We hypothesize that a customized Swallow Exercise Aid (SEA), developed for isometric and isokinetic strengthening exercises (against resistance), can help to functionally strengthen the suprahyoid musculature, which in turn can improve swallowing function. An effectiveness/feasibility study was carried out with ten senior healthy volunteers, who performed exe...

Videofluoroscopic Validation of a Translational Murine Model of Presbyphagia
This study provides novel evidence that otherwise healthy aging B6 mice indeed develop age-related changes in swallow function resembling presbyphagia in humans. Specifically, aging B6 mice have a generally slow swallow that spans all stages of swallowing: oral, pharyngeal, and esophageal. The next step is to build upon this foundational work by exploring the responsible mechanisms of presbyphagia in B6 mice. (Source: Dysphagia)

The Effect of Prophylactic Percutaneous Endoscopic Gastrostomy (PEG) Tube Placement on Swallowing and Swallow-Related Outcomes in Patients Undergoing Radiotherapy for Head and Neck Cancer: A Systematic Review
Abstract Patients undergoing radiotherapy for head and neck cancer (HNC) often experience malnutrition and dehydration during treatment. As a result, some centres place PEG tubes prophylactically (pPEG) to prevent these negative consequences. However, recent research has suggested that pPEG use may negatively affect swallowing physiology, function and/or quality of life, especially in the long term. The purpose of this study was to systematically review the literature on pPEG use in HNC patients undergoing radiotherapy and to determine its impact on swallowing-related outcomes. The following electronic databases w...

Neural Network Pattern Recognition of Lingual–Palatal Pressure for Automated Detection of Swallow
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 tee...

Swallowing Problems at the End of the Palliative Phase: Incidence and Severity in 164 Unsedated Patients
This study suggests that incidence of swallowing problems at the end of the palliative phase is high and that these difficulties may not only result in discomfort for patients, but also can raise concern for caregivers. More information and education on management of swallowing problems in palliative settings might be needed for both relatives and nursing staff. However, the data also suggest that any intervention should be proportional to the level of distress caused by the intervention. (Source: Dysphagia)

Afferent Nerve Ending Density in the Human Laryngeal Mucosa: Potential Implications on Endoscopic Evaluation of Laryngeal Sensitivity
Abstract Laryngeal sensitivity is crucial for maintaining safe swallowing, thus avoiding silent aspiration. The sensitivity test, carried out by fiberoptic endoscopic examination of swallowing, plays an important role in the assessment of dysphagic patients. The ventricular folds appear to be more sensitive than the epiglottis during the sensitivity test. Therefore, this study aimed to investigate the mechanical sensitivity of the supraglottic larynx. In seven healthy adults undergoing microlaryngoscopy to remove vocal cord polyps, we excised mucosal samples from the epiglottis and ventricular folds. We measured a...
