BACKGROUND/AIMS: Substance P (SP) is a neuropeptide, likely acting as a neurotransmitter in the pharyngeal mucosa enhancing the swallow and cough reflex. Pharyngeal Electrical Stimulation (PES) induces a temporary increase of salivary SP levels in healthy adults. Previous evidence suggests that post-stroke dysphagia is related to reduced SP levels. Here, we investigated the effects of PES on SP levels in severely dysphagic stroke patients and a possible link between increase of SP and treatment success...

BACKGROUND AND PURPOSE: The role of afferent sensory pathways in the pathophysiology of post-stroke oropharyngeal dysphagia is not known. We hypothesized that patients with chronic post-stroke dysphagia (PSD) would show impaired sensory cortical activation in the ipsilesional hemisphere. METHODS: We studied 28 chronic unilateral post-stroke patients [17 PSD and 11 post-stroke non-dysphagic patients (PSnD)] and 11 age-matched healthy volunteers. Event-related sensory-evoked potentials to pharyngeal stimulation (pSEP) and sensory thresholds were assessed...

The laryngeal adductor reflex (LAR) is an airway protective reflex that manifests as a brief vocal fold closure in response to laryngeal stimulation. This study examined if the absence of the LAR in response to touch delivered by a laryngoscope is associated with penetration/aspiration or pneumonia in patients with dysphagia. Inpatients at a teaching hospital with clinical symptoms of dysphagia were recruited upon referral to the otolaryngology clinic for a swallowing evaluation. Otolaryngologists observed the status of secretions and touched each arytenoid with the tip of the laryngoscope...

BACKGROUND: Oropharyngeal sensory impairment is a potential target to treat swallowing dysfunction in patients with oropharyngeal dysphagia (OD). AIM: To assess the therapeutic effect of stimulating oropharyngeal sensory afferents with TRPV1, TRPA1, or TRPM8 agonists vs increasing bolus viscosity in older and neurologic patients with OD by comparing four studies of similar experimental design. METHODS: Swallow function of 142 older patients with impaired safety of swallow at nectar ([50-350] mPa·s) viscosity was evaluated with videofluoroscopy (VFS) while treated with TRPV1 (150 μmol/L), TRPV1/A1 (150 μmol/L and 1 mmol/L), or TRPM8 (1 mmol/L or 10 mmol/L) agonists or modified starch (MS) at spoon thick viscosity (>1750 mPa·s)...

Sensory input can alter swallowing control in both the cortex and brainstem. Electrical stimulation of superior laryngeal nerve afferents increases reflexive swallowing in animals, with different frequencies optimally effective across species. Here we determined 1) if neck vibration overlying the larynx affected the fundamental frequency of the voice demonstrating penetration of vibration into the laryngeal tissues, and 2) if vibration, in comparison with sham, increased spontaneous swallowing and enhanced cortical hemodynamic responses to swallows in the swallowing network...

Oropharyngeal dysphagia (OD) is a condition recognized by the World Health Organization and defined as the difficulty or inability to move a bolus safely and effectively from the oral cavity to the esophagus, and can include aspirations, choking, and residue. OD is pandemic among different phenotypes of older people, affecting between 27% and 91% of the population 70 years or older. Although OD can be diagnosed by well-defined clinical methods and complementary explorations, in the clinical setting OD is seldom systematically screened and treated, and awareness among the medical/geriatric community is scarce...

Acute stroke patients with dysphagia are at risk of developing pulmonary infection, which increases the risk of death. Therefore, optimal management of dysphagia is essential; however, available evidence supporting the effectiveness of dysphagia treatments is limited. Surface electrical stimulation (e-stim) has been developed as a new treatment modality for dysphagia. In this study, we investigated the efficacy of surface sensory e-stim therapy in preventing pulmonary infection in 53 acute stroke patients with dysphagia...

Oropharyngeal dysphagia (OD) is a prevalent geriatric syndrome. Treatment is based on compensatory strategies to avoid complications. New treatments based on sensory stimulation to promote the recovery of the swallowing function have proved effective in acute studies but prolonged treatment needs further research. Our aim was to evaluate and compare the effect of two, longer-term sensory treatment strategies on older patients with OD. 38 older patients (≥70 years) were studied with videofluoroscopy (pre/posttreatment) and randomized into two 10-day treatment groups: Group A-transient receptor potential vanilloid 1 (TRPV1) agonist (capsaicin 1 × 10(-5) M) and Group B-transcutaneous sensory electrical stimulation (TSES) (Intelect VitalStim, biphasic pulses, 300 μs, 80 Hz)...

BACKGROUND: Oropharyngeal dysphagia (OD) is a highly prevalent symptom in older people. Appropriate oropharyngeal sensory feedback is essential for safe and efficient swallowing. However, pharyngeal sensitivity decreases with advancing age and could play a fundamental role in the physiopathology of swallowing dysfunction associated with aging. We aimed to characterize pharyngeal sensitivity and cortical response to a pharyngeal electrical stimulus in healthy volunteers (HV) and older patients with and without OD...

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...

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...

BACKGROUND: Acute Idiopathic Polyradiculoneuritis, an animal model for the axonal form of the Guillain - Barre Syndrome in humans and the acquired myasthenia gravis are different autoimmune disorders affecting the peripheral nerves and the neuromuscular junction, respectively. Both lead to muscle weakness and possible respiratory failure. The coexistence of these two entities combined in the same patient is rare in humans and, to our knowledge, the present case is the first reported in dogs...

The pharynx is a locus of provocation among infants with aerodigestive morbidities manifesting as dysphagia, life-threatening events, aspiration-pneumonia, atelectasis, and reflux, and such infants often receive nasal respiratory support. We determined the impact of different oxygen delivery methods on pharyngeal stimulation-induced aerodigestive reflexes [room air (RA), nasal cannula (NC), and nasal continuous positive airway pressure (nCPAP)] while hypothesizing that the sensory motor characteristics of putative reflexes are distinct...

Dysphagia is a very common occurrence in Huntington's disease (HD). As such, many people with HD require texture modified diets. This commentary discusses the implications for individuals living long-term on modified diets, including the loss of sensory stimulation and dietary enjoyment. Clinical practice analyses of two interventions aimed at promoting dietary satisfaction and involvement in food preparation for those with HD are described and parameters for future research are discussed.

Cough and swallowing reflexes are important airway-protective mechanisms against aspiration. Angiotensin-converting enzyme (ACE) inhibitors, one of the side effects of which is cough, have been reported to reduce the incidence of aspiration pneumonia in hypertensive patients with stroke. ACE inhibitors have also been reported to improve the swallowing function in post-stroke patients. On the other hand, stimulation of the Arnold nerve, the auricular branch of the vagus, triggers the cough reflex (Arnold's ear-cough reflex)...

OBJECTIVE: Post-tonsillectomy pain is believed to be mediated by noxious stimulation of C-fiber afferents located in the peritonsillary space, and local anesthetic infiltration to this area may decrease pain by blocking the sensory pathways and thus preventing the nociceptive impulses. We aimed to compare the effects of different concentrations of preincisional peritonsillar levobupivacaine (0.25% and 0.5%) infiltration on postoperative pain and bleeding in a placebo-controlled design...

Little is known about the mucosal phenotype of the proximal human esophagus. There is evidence to suggest that the proximal esophagus is more sensitive to chemical and mechanical stimulation compared with the distal. This may have physiological relevance (e.g., in prevention of aspiration of gastroesophageal refluxate), but also pathological relevance (e.g., in reflux perception or dysphagia). Reasons for this increased sensitivity are unclear but may include impairment in mucosal barrier integrity or changes in sensory innervation...
