Filter by:The investigators main endpoint was focused on the analysis of the type, rate and the impact of different clinical parameters on the complications of the PEG tube placements performed at the Department of Otorhinolaryngology - Head and Neck Surgery since October 2008. In addition, the investigators aimed to compare the results with a historic cohort patient group (September 2005 - October 2008) sent to the Department of Surgery for PEG tube placement in order to evaluate the results of the changed routine.
The purpose of this study is to learn about the safety and usefulness of a procedure called endoscopic submucosal myotomy, which is a new technique in the treatment of achalasia. Achalasia is a disorder involving the lack of smooth muscle relaxation and sustained high pressure in the sphincter (muscle) of the lower esophagus. This may result in symptoms such as difficulty in swallowing, chest pain, regurgitation of food and eventually, weight loss. For more than a decade, a laparoscopic surgical procedure known as Heller myotomy has been the primary treatment for achalasia in patients with low surgical risk. In Heller myotomy, the surgeon makes three to four small abdominal incisions, inserts tube-like instruments through them, and once inside, the junction between the esophagus and stomach is found, a lengthwise incision is made on the muscular ring surrounding the lower esophageal sphincter which weakens the muscle and the lower esophageal sphincter or muscle (LES) is then able to open more easily. However, there is an emerging field known as natural orifice (opening) transluminal (through the lumen) endoscopic surgery (NOTES). This approach involves passing an endoscope - a thin tube with a built-in camera, light and minuscule tools through the natural opening in the body, like the mouth in order to perform less invasive surgery without any external wounds or scars. The procedure is done using the Submucosal Endoscopy with Mucosal Flap (SEMF) technique which involves passing an endoscope through the mouth into the esophagus, where a small incision is made on the lining of the esophagus, known as the mucosa. A balloon is then inserted and dilated in the submucosa - the layer between the inner lining of the esophagus and the outer wall consisting of the muscle of the esophagus. Dilation of the balloon in the submucosa creates a tunnel that allows insertion of the endoscope and access to the muscle of the lower esophageal sphincter (LES). A long incision is then carefully made on the posterior portion of the muscular ring that forms the LES. The incision divides the muscle fibers of the LES, which weakens the muscle, allowing for the easier passage of food while preserving some valve function to prevent reflux of acid from the stomach into the esophagus. The expected duration of participation is up to 10 years from the time study participants undergo the endoscopic surgical procedure.
Parkinson's disease (PD) is a chronic, degenerative disease described by motors and non-motors symptoms. Changes in swallowing and respiratory dynamics increase risk of tracheal aspiration largely responsible for increased morbidity and mortality in this population. Thus, interdisciplinary rehabilitation strategies can reduce the complications of dysphagia, with consequent improvement of the prognosis of individuals with PD. Objective: To determine the impact of combined oral motor exercises and breathing exercises on swallowing disorders in individuals with PD. Method: Clinical trial, randomized and blinded for the examinator. For all subjects will be given the stage of PD and applied quality of life questionnaire. The swallowing complaints will be investigated through structured questionnaire and functional aspects of swallowing with videofluoroscopy. The Manovacuometry Spirometry will determine measures of respiratory function. The assessment of vocal and speech disorders will be done with perceptive, acoustic, aerodynamic and electroglottographic measures as well as analysis of intelligibility. Three groups of intervention will be defined: one of them doing oral motor exercises for swallowing, one doing breathing exercises and another must do this two interventions combined. Effect of intervention will be assessed through measures of swallowing, breathing, voice and speech. The groups will be compared, according to the principle of "intention to treat" by appropriate statistical tests, according to the distribution of the dependent variables.
Swallowing disorders (dysphagia) are common in adult patients. There is emerging evidence that dysphagia itself can cause adverse medical outcomes. There is a three-fold increased risk for pneumonia in these patients versus similar patients without dysphagia. Patients with dysphagia also suffer poor nutrition and dehydration. Patients can become so malnourished that it slows their recovery. Dysphagia can cause choking when food or liquid enters the lungs. Over time, this will cause pneumonia and even death. More acutely, patients fear that their choking will cause them to suffocate and die. Over time, patients are embarrassed to be seen choking and thus feel forced to dine alone. These patients report feelings of isolation and depression. To date, there are no practical methods to assess these adverse outcomes of swallowing difficulties in patients. This research will be the first to address this gap. Specifically, as part of previous research (PhD dissertation by RM, the PI) a new measure of medical outcomes of dysphagia was developed, titled the Medical Outcomes of Dysphagia (MOD) scale. The MOD consists of 3 subscales that each measure lung, nutrition-hydration or psychological consequences in patients with swallowing difficulties. Unlike more expensive and complex tests, the MOD has been designed for both in- and outpatients. This research will validate each MOD subscale to ensure retention of only items that are reliable and valid for use with patients who have dysphagia due to any disease etiology. The final MOD subscales will be the first to allow clinicians to track medical complications in their patients and to ensure that treatment is effective. Globally, the MOD subscales will direct limited health care resources to the most effective treatments for swallowing disorders.
Despite medical advances, half of the patients admitted to hospital for recovery from acute illness, injury or surgery have swallowing difficulties and those requiring tubes for breathing support are at even greater risk. Difficulties with swallowing decrease patients' quality of life, prolong their hospital stay, as well as lead to medical complications such as pneumonia, malnutrition and death. Presently, there is no screening test for swallowing difficulties in patients who have required respiratory support. Screening will allow for early detection of swallowing problems which is important to prevent serious complications, such as pneumonia. This research will determine the accuracy of a new screening test, the Toronto Bedside Swallowing Screening Test (TOR-BSST©) previously tested with stroke patients, to predict the presence of swallowing difficulties in patients who have required breathing support for longer than 48 hours. The investigators will enroll 100 patients from the intensive care medical surgical units at the University Health Network. The findings from this research will help identify those patients with swallowing problems earlier than it is currently possible. Once identified, at risk patients will be referred to a speech language pathologist swallowing expert for more comprehensive testing; thereby, decreasing their risk of experiencing serious complications, such as pneumonia, secondary to swallowing problems.
The purpose of this study is to determine if using 20 mL B.Braun syringes to inflate LMAs and allowing them to recoil will put the pressure of the LMA cuff within the safety range. It will also determine if remaining within this safety range has an effect on complications after surgery..
People with swallowing impairment experience particular difficulty swallowing thin liquids safely; the fast flow of liquids makes them difficult to control. The tongue plays a critical role in containing liquids in the mouth, channeling the direction of their flow towards the pharynx (throat) and controlling their flow along that channel. The investigators are engaged in a program of research to better understand tongue function in swallowing, particularly with respect to controlling the flow of liquids. In this study the investigators will compare two different tongue-pressure resistance training protocols, to determine whether a protocol that emphasizes strength-and-accuracy or one that emphasizes pressure timing work better for improving liquid flow control in swallowing.
Oropharyngeal dysphagia (OD, swallowing dysfunction) is a major complaint following stroke. Despite its enormous impact on functional capacity, quality of life, and survival, OD is both underestimated and underdiagnosed as a cause of major nutritional and respiratory complications in stroke patients. A recent systematic review on the effects of rehabilitation therapy on OD concluded that although some positive effects were found, the number of studies was small, many of them had methodological problems and there was a need for further research using randomized controlled trials. Transcutaneous electrical stimulation was approved by the FDA as a treatment of dysphagia in June 2001 and is traditionally used to activate pharyngeal muscles through stimulation of peripheral motor nerves (neuromuscular electrical estimulation, NMES). However, their real effectiveness and safety in the treatment of dysphagia is still matter of discussion (Logemann Dysphagia 2007, Ludlow dysphagia 2007) and studies evaluating NMES therapy, present discordant results. On the other hand, in recent years, transcutaneous electrical stimulation is beginning to use as a sensory strategy (Gallas 2010), avoiding muscle contraction during the treatment.Our research strategy includes the assessment of the therapeutic effect of these two main strategies using transcutaneous electrical stimulation on swallow physiology and clinical outcomes of post-stroke dysphagic patients.
The purpose of this study is to find out if doing prophylactic or preventative swallowing exercises from the start of cancer treatment can improve the ability to swallow when the treatment is completed and beyond.
The investigators aim is to try to rehabilitate post stroke dysphagia using electrical stimulation of the mylohyoid muscles.
