BACKGROUND Emergency medical technicians intubate patients in unfamiliar surroundings and with less than ideal positioning. This study was designed to evaluate advanced life support (ALS) emergency medical technicians' (EMTs) ability to successfully intubate a simulated airway using a video-assisted semi-rigid fiberoptic stylet, the Clarus Video System (CVS). METHODS ALS EMTs were first shown...

Massive hematochezia caused by a small bowel lesion is a rare entity. Currently, video capsule endoscopy and balloon-assisted enteroscopy are effective in identifying the source of small intestine bleeding. Herein, we report a case of small bowel bleeding caused by a nonmucinous appendiceal adenocarcinoma with ileal invasion which was detected by video capsule endoscopy and single-balloon endos...

CONTEXT Laryngeal sensitivity is important in the coordination of swallowing coordination and avoidance of aspiration. OBJECTIVE To briefly review the physiology of swallowing and report on our experience with laryngeal sensitivity evaluation among patients presenting dysphagia. TYPE OF STUDY Prospective. SETTING Endoscopy Department, Hospital Sírio-Libanês. METHODS Clinical data, endos...

We report a case of a 79-year-old female presenting with hematemesis and melena 9 years after ventral hernioplasty with mesh. After initial normal endoscopy and colonoscopy, video capsule endoscopy revealed a metallic wire mesh perforating the jejunum. Abdominal computed tomography did not identify a perforation although metallic mesh was visualized close to the small bowel. We present the firs...

in this paper, we propose a new full-fuzzy video ratecontrol algorithm (rca) for variable bit rate (vbr) videoapplications. the proposed rca provides high qualitycompressed video with a low degree computational complexity.by controlling the quantization parameter (qp) on a picturebasis, it produces vbr video bit streams. the proposed rcahas been implemented on the jm h.264/avc video codec andth...

Background. Teaching direct laryngoscopy is limited by the inability of the instructor to simultaneously view the airway with the laryngoscopist. Our primary aim is to report our initial use of the GlideScope Direct, a video-enabled, Macintosh laryngoscope intended primarily as a training tool in direct laryngoscopy. Methods. The GlideScope Direct was made available to anyone who planned on per...

Background: Training of airway management and tracheal intubation skill in emergencies for resuscitation of patients are basic skills for medical students. However, the success rate of beginners in this skill is low. Video laryngoscopes are new devices that can increase the success of endotracheal intubation training. Methods: This clinical trial was conducted with 30 medical students who came...
