Motor Function of the Pharynx, Esophagus, and Its Sphincters by Ravinder Mittal Pdf

Deglutition or a swallow begins as a voluntary act in the oral cavity but proceeds autonomously in the pharynx and esophagus. Bilateral sequenced activation and inhibition of more than 25 pairs of muscles of mouth, pharynx, larynx, and esophagus is required during a swallow. A single swallow elicits peristalsis in the pharynx and esophagus along with relaxation of upper and lower esophageal sphincters. Multiple swallows, at closely spaced time intervals, demonstrate deglutitive inhibition; sphincters remain relaxed during the entire period, but only the last swallow elicits peristalsis. Laryngeal inlet closure or airway protection is very important during swallow. Upper part of the esophagus that includes upper esophageal sphincter is composed of skeletal muscles, middle esophagus is composed of a mixture of skeletal and smooth muscles, and lower esophagus, including lower esophageal sphincter, is composed of smooth muscles. Peristalsis progresses in seamless fashion, despite separate control mechanism, from the skeletal to smooth muscle esophagus. The esophagus's circular and longitudinal muscle layers contract synchronously during peristalsis. Sphincters maintain continuous tone; neuromuscular mechanisms for tonic closure in the upper and lower esophageal sphincters are different. Lower esophageal sphincter transient relaxation, belching mechanism, regurgitation, vomiting, and reflux are mediated via the brain stem.

Radiology of the Pharynx and the Esophagus by Olle Ekberg Pdf

All aspects of radiology of the pharynx and esophagus are coverd in detail. The text covers anatomy, physiology, examination techniques, and describes all relevant disease entities. However, it also considers endoscopic and manometric aspects of interest to the radiologist. Moreover, it has a broad clinical approach, encompassing not only analysis of symptoms but also topics such as the social and mental burden of dysphagia. Interventions in the esophagus from the radiologist's and the endoscopist's points of view are also addressed. The authors are all renowned experts in their field. Although it is assumed that most readers will be radiologists, much information will be of interest to other specialists involved in the evaluation and treatment of dysphagia, including ENT surgeons, thoracic surgeons, thoracic surgeons, speech and language pathologists, phoniatricians, gastroenterologists, and neurologists.

The Yale Pharyngeal Residue Severity Rating Scale by Steven B. Leder,Paul D. Neubauer Pdf

This text is a reliable, validated, anatomically defined, and image-based tool to determine residue location and severity when performing fiberoptic endoscopic evaluation of swallowing (FEES). Based upon research by Drs. Leder and Neubauer, an easily interpreted, readily learned, and hierarchically organized pharyngeal residue severity rating scale was developed for speech-language pathologists, otolaryngologists, and other health care professionals who perform and interpret FEES. The Yale Pharyngeal Residue Severity Rating Scale works equally well for any swallow of interest, whether it is the first, subsequent clearing, or last swallow. The endoscopist simply has to match their chosen swallow with its scale mate. The Yale Pharyngeal Residue Severity Rating Scale can be used for both clinical advantages and research opportunities. Clinically, clinicians can now accurately classify vallecula and pyriform sinus residue severity as none, trace, mild, moderate, or severe for diagnostic purposes, determination of functional therapeutic change, and precise dissemination of shared information. Research uses include tracking outcomes for clinical trials, investigating various swallowing interventions, demonstrating efficacy of specific interventions to reduce pharyngeal residue, determining morbidity and mortality associated with pharyngeal residue in different patient populations, and improving the training and accuracy of FEES interpretation by students and clinicians. The Yale Pharyngeal Residue Severity Rating Scale is an important addition to the deglutologist’s tool box.

Asbestos by Institute of Medicine,Board on Population Health and Public Health Practices,Committee on Asbestos: Selected Health Effects Pdf

In conjunction with drafting comprehensive legislation concerning compensation for health effects related to asbestos exposure (the Fairness in Asbestos Injury Act), the Senate Committee on the Judiciary directed the Institute of Medicine to assemble the Committee on Asbestos: Selected Health Effects. This committee was charged with addressing whether asbestos exposure is causally related to adverse health consequences in addition to asbestosis, mesothelioma, and lung cancer. Asbestos: Selected Cancers presents the committee's comprehensive distillation of the peer-reviewed scientific and medical literature regarding association between asbestos and colorectal, laryngeal, esophageal, pharyngeal, and stomach cancers.
