REVIEW
M A Peyron, A Woda, P Bourdiol, M Hennequin
The paper reviews human mastication, focusing on its age-related changes. The first part describes mastication adaptation in young healthy individuals. Adaptation to obtain a food bolus ready to be swallowed relies on variations in number of cycles, muscle strength and volume of emitted saliva. As a result, the food bolus displays granulometric and rheological properties, the values of which are maintained within the adaptive range of deglutition. The second part concerns healthy aging. Some mastication parameters are slightly modified by age, but aging itself does not impair mastication, as the adaptation possibilities remain operant...

PURPOSE: While the presence of dysphagia following partial glossectomy has been widely reported, there is insufficient quality evidence to guide clinical decision making about the treatment of this disorder. This study investigated a novel dysphagia rehabilitation approach using ultrasound tongue imaging for patient training. METHOD: Initially, a pilot study was conducted to investigate the feasibility of ultrasound visual feedback during swallow tasks. The protocol was then replicated using a single-case experimental designed study to investigate therapeutic effect...

BACKGROUND: Gastroesophageal reflux (GER) has been associated with idiopathic pulmonary fibrosis (IPF). Pathogenesis may be related to chronic micro-aspiration. We aimed to assess objective measures of GER on multichannel intraluminal impedance and pH study (MII-pH) and their relationship with pulmonary function testing (PFT) results, and to compare the performance of pH/acid reflux parameters vs corresponding MII/bolus parameters in predicting pulmonary dysfunction in IPF. METHODS: This was a retrospective cohort study of IPF patients undergoing prelung transplant evaluation with MII-pH off acid suppression, and having received PFT within 3 months...

The purpose of this study was to compare videofluoroscopy (VFS), fiberoptic endoscopic evaluation of swallowing (FEES) and oro-pharyngo- oesophageal scintigraphy (OPES) with regards to premature spillage, post-swallowing residue and aspiration to assess the reliability of these tests for detection of oro-pharyngeal dysphagia. Sixty patients affected with dysphagia of various origin were enrolled in the study and submitted to VFS, FEES and OPES using a liquid and semi-solid bolus. As a reference, we used VFS...

The mechanism of swallowing is still not fully understood, because the process of swallowing is a rapid and complex interaction among several involved organs and the food bolus. In this work, with the aim of studying swallowing and aspiration processes noninvasively and systematically, a computer simulation method for analyzing the involved organs and water (considered as the food bolus) is proposed. The shape and motion of the organs involved in swallowing are modeled in the same way as in our previous study, by using the Hamiltonian moving particle simulation (MPS) method and forced displacements on the basis of motion in a healthy volunteer...

OBJECTIVES/HYPOTHESIS: Deformities of the anterior cervical spine are an established cause of dysphagia. Whereas osteophytes and spinal fusion hardware have been reported to alter bolus flow and contribute to swallowing dysfunction, the relationship between abnormal spine curvature and swallowing dysfunction is not established. The purpose of this investigation was to evaluate the association between cervical kyphosis and objective measures of swallowing dysfunction on videofluoroscopy...

Recurrent laryngeal nerve (RLN) damage in infants leads to increased dysphagia and aspiration pneumonia. Recent work has shown that intraoral transport and swallow kinematics change following RLN lesion, suggesting potential changes in bolus formation prior to the swallow. In this study, we used geometric morphometrics to understand the effect of bolus shape on penetration and aspiration in infants with and without RLN lesion. We hypothesized (1) that geometric bolus properties are related to airway protection outcomes and (2) that in infants with RLN lesion, the relationship between geometric bolus properties and dysphagia is changed...

OBJECTIVES/HYPOTHESIS: Dysphagia is one of the most significant side effects of the treatment of head and neck cancer. Residue and aspiration are two indicators of dysphagia, but aspiration is historically the only indicator of interest, because it may impact health outcomes. Clinicians have anecdotally used residue as another marker of swallowing dysfunction, but it is understudied. This project investigated the impact of aspiration versus residue on function and quality of life (QoL) in these patients...

Prader-Willi Syndrome (PWS) is caused by a genetic imprinting abnormality resulting from the lack of expression of the paternal genes at 15q11-q13. Intellectual disability, low muscle tone, and life-threatening hyperphagia are hallmarks of the phenotype. The need for the Heimlich maneuver, death from choking, and pulmonary infection occur in a disproportionally high number of persons with PWS. The widely held belief is that eating behaviors are responsible for choking and aspiration; yet, no investigation had sought to determine if swallowing impairments were present in persons with PWS...

BACKGROUND: Spinal anesthesia is a preferred technique over general anesthesia for cesarean delivery. It avoids maternal airway related complications, aspiration and neonatal depression. However hypotension following spinal anesthesia can lead to decrease in uterine blood flow and neonatal hypoxia. AIMS: We aimed to evaluate the efficacy of 15 mL.kg- 1of crystalloid preloading versus prophylactic intravenous bolus of 10 mg ephedrine as an antihypotensive measure for cesarean section...

BACKGROUND: We assessed performance of 6 aspiration catheters for distal embolization using a distal protection filter in an in vitro experiment. In acute myocardial infarction, a distal protection filter is used for lesions likely to induce a distal embolism. Which aspiration cathether is most effective when used with a distal protection filter remains still unclear. METHODS: A 0.5-cm3 bolus of gelatin as a model of stagnant pools of coronary plaque debris was captured in the distal protection filter and aspirated by 6 aspiration catheters...

REVIEW
An Moonen, Guy Boeckxstaens
Achalasia is a primary esophageal motor disorder of the esophagus that is characterized by the absence of esophageal peristalsis and a failure of the lower esophageal sphincter (LES) to relax upon swallowing. The defective relaxation leads to symptoms of dysphagia for solids and liquids, regurgitation, aspiration, chest pain, and weight loss. Achalasia is believed to result from a selective loss of enteric inhibitory neurons, most likely due to an autoimmune phenomenon in genetic susceptible individuals. As there is no curative treatment for achalasia, treatment is confined to disruption of the LES to improve bolus passage...

BACKGROUND: Head and neck cancer treatment has developed over the last decade, with improved mortality and survival rates, but the treatments often result in dysphagia (a difficulty in swallowing) as a side effect. This may be acute, resolving after treatment, or remain as a long-term negative sequela of head and neck cancer (HNC) treatment. Interventions to counteract the problems associated with dysphagia include swallowing exercises or modification of diet (bolus texture, size), or both...

Background/Aims: We attempted to examine the relationship between abnormal findings on high-resolution manometry (HRM) and videofluoroscopic swallowing study (VFSS) of the pharynx and upper esophageal sphincter (UES), and to identify the risk factors for aspiration. Methods: We performed VFSS and HRM on the same day in 36 ischemic stroke patients (mean age, 67.5 years) with dysphagia. Pressure (basal, median intra bolus, and nadir), relaxation time interval of the UES, and mesopharyngeal and hypopharyngeal contractility (as a contractile integral) were examined using HRM...

Achalasia is a primary esophageal motility disorder with an estimated annual incidence of 1 per 100,000 persons. It is characterized by the absence of esophageal peristalsis and failure of the lower esophageal sphincter (LES) to relax upon swallowing, resulting in progressively severe dysphagia for solids and liquids, regurgitation, aspiration, chest pain and weight loss. Achalasia results from a loss of enteric neurons, most likely due to an autoimmune reaction in patients with a particular immunogenetic background...
