Background Functional characteristics of the pharynx and upper esophagus, including aspiration episodes, were investigated in 14 awake volunteers during various levels partial neuromuscular block. Pharyngeal function was evaluated using videoradiography computerized pharyngeal manometry contrast bolus swallowing. Methods Measurements constrictor muscle (contraction amplitude, duration, slope), esophageal sphincter resting tone, coordination, transit time, under fluoroscopic control...

Delayed contrast-enhanced MRI of cartilage (dGEMRIC) is a noninvasive technique to study glycosaminoglycan (GAG) content in vivo. This evaluates dGEMRIC patients with preradiographic degenerative changes. Seventeen knees 15 (age 35-70) arthroscopically verified changes (softening and fibrillations) the medial or lateral femoral compartment, knee pain, normal weight-bearing radiography were included. (1.5 T) was performed precontrast at 1.5 3 hr after an intravenous injection Gd-DTPA(2-) 0.3...

Residual neuromuscular block caused by vecuronium alters pharyngeal function and impairs airway protection. The primary objectives of this investigation were to radiographically evaluate the swallowing act record incidence mechanism behind dysfunction during partial block. secondary objective was effect atracurium on function.Twenty healthy volunteers studied while awake liquid-contrast bolus swallowing. fluoroscopy. initiation process, coordination, transit time evaluated. Simultaneous...

Abstract Background Epidemiological reports on risk and prognostic factors in patients with mesenteric venous thrombosis (MVT) are scarce. Methods Patients MVT were identified through the inpatient autopsy registry between 2000 2006 at Malmö University Hospital. Results Fifty-one had MVT, diagnosed six. The highest incidence (11·3 per 100 000 person-years) was age category 70–79 years. Activated protein C resistance present 13 of 29 tested. D-dimer admission raised all five Multidetector row...

Abstract To evaluate the prevalence of abdominal aortic dilatations among asymptomatic brothers and sisters patients with aneurysms (AAAs), an ultrasonographic screening study was performed. One hundred two siblings operated on for AAAs at Swedish hospitals were invited to attend, 87 them (35 men 52 women) from 32 different families, accepted invitation. Their median age 63 years (range 39–82 years). Aortic dilatation diagnosed in ten (29 per cent) three (6 cent). In cases (eight there a...

Conventional single-radiograph technique and cineradiography were used for examination of the pharyngo-esophageal junction area during contrast medium swallowing in 500 patients with dysphagia 150 volunteers no complaints. Seventeen pharyngoesophageal diverticula found, emerging lateral or latero-anterior direction just below cricopharyngeal muscle indentation. Of these, 13 had wide openings seven narrow openings; these forms differed shape retention material cycle. The delineation...

Defecography is a technique of examining the rectum and anal canal in which patient studied while sitting down rather than recumbent recordings are obtained both at rest during straining. The authors describe their findings 83 patients with dyschezia. Defecation was normal 28 patients. Prolapse mucosa seen 13 internal procidentia 23, 12 whom also had intussusception manifested as rectal prolapse. A deep rectogenital fossa associated an enterocele 16 patients; proctocele, fecal retention 5....

Patients who suffer from chewing and swallowing disorders, i.e. dysphagia, may have difficulties ingesting normal food liquids. In these patients a texture modified diet enable that the patient maintain adequate nutrition. However, there is no generally accepted definition of 'texture' includes measurements describing different textures.Objectively define quantify categories texture-modified by conducting rheological sensory analyses. A further objective was to facilitate communication...

Intact pharyngeal function and coordination of breathing swallowing are essential for airway protection to avoid respiratory complications. Postoperative pulmonary complications caused by residual effects neuromuscular-blocking agents occur more frequently in the elderly. Moreover, elderly have altered which is associated with increased risk aspiration. The purpose this study was evaluate partial neuromuscular block on function, swallowing, individuals older than 65 yr.Pharyngeal were...

The negatively charged contrast agent Gd-DTPA2- distributes inversely to the cartilage fixed density. This enables structural examinations by contrast-enhanced MRI. In line with development of a clinically applicable protocol for such examinations, this study describes temporal pattern distribution in femoral knee at three different doses healthy volunteers. Nineteen volunteers (ages 21-28 years) were examined 1.5T MRI system. Quantitative relaxation rate measurements made weight-bearing...

Background Anesthetic agents alter pharyngeal function with risk of impaired airway protection and aspiration. This study was performed to evaluate during subhypnotic concentrations propofol, isoflurane, sevoflurane compare the drugs for possible differences in this respect. Methods Forty-five healthy volunteers were randomized receive or sevoflurane. During series liquid contrast bolus swallowing, fluoroscopy simultaneous solid state videomanometry used incidence dysfunction, initiation...

Purpose: To analyze how carbonated thin liquids affected the physiology of swallowing in dysphagic patients.Material and Methods: 40 patients were analyzed; 36 neurologically impaired.During a therapeutic videoradiographic examination had to swallow with following consistencies three times: thin, thickened carbonated.The given doses 3 Â 5 ml.The swallows analyzed regarding penetration/aspiration, pharyngeal transit time retention.Results: Significant difference was found...

Many children with cerebral palsy have feeding difficulties. The aim of this study was to investigate if trunk and neck positioning influenced oral pharyngeal swallow. Five problem aged 3‐10 years were examined using videofluoroscopy. All had tetraplegia dystonia, i.e. poor head control stability. gross aspiration posterior leak. phase delayed in relation the phase. Two retention. positioned both an extended flexed neck. position combined a 30 o reclined sitting position. In positions they...
