BACKGROUND & AIMS The aim of this study was to determine the mechanism for recovery of swallowing after dysphagic stroke. METHODS Twenty-eight patients who had a unilateral hemispheric stroke were studied 1 week and 1 and 3 months after the stroke by videofluoroscopy. Pharyngeal and thenar electromyographic responses to magnetic stimulation of multiple(More)
Fifty-six patients with Barrett's oesophagus diagnosed between 1977 and 1986 were prospectively studied by 6-monthly endoscopic surveillance and biopsy. During follow-up to-date, four patients have developed high-grade dysplasia and three have adenocarcinoma of the oesophagus. Two of the adenocarcinomas were preceded by progressively severe dysplastic(More)
Symptomatic assessment and oesophageal investigations were done in 25 consecutive patients with the irritable bowel syndrome attending a gastroenterological clinic. Symptoms of gastro-oesophageal reflux, dysphagia, and a globus sensation were significantly commoner than in a control group of fracture clinic patients. Ambulatory oesophageal pH monitoring(More)
Faucial pillar (FP) stimulation is commonly used in swallowing rehabilitation, yet its physiological basis remains uncertain. We investigated the effects of intraoral FP stimulation on human corticobulbar excitability and swallowing behavior, to explore the possibility of a central mechanism for functional change. In 10 healthy subjects, corticobulbar(More)
Between January 1994 and December 1996 72 patients were treated with 76 Gianturco oesophageal stents for oesophageal obstruction or perforation. The patients were followed prospectively in order to determine the effectiveness in improving dysphagia, to establish long term patency, survival times and complications. The mean dysphagia score prior to stenting(More)
Over a 5-year period, 54 intra-abdominal abscesses were observed in 40 (20.8%) of 192 patients with Crohn's disease. The median age was 39 years (range 17-76 years); median interval from diagnosis, 7.5 years (range 0-24 years) and the median number of surgical operations was 2 (range 0-7). Forty abscesses (74.1%) were spontaneous and 14 (25.9%) were(More)
An imaging strategy is crucial in patients who have sustained a traumatic disruption of the thoracic aorta. Of those who reach hospital alive, 70-90 per cent will survive if diagnosed early and treated appropriately. The clinician has many imaging techniques to choose from, but they vary considerably in their degree of accuracy and performance time.(More)
Traditionally, patients with suspected or known and possible recurrent Crohn's disease have been investigated by small bowel barium radiology, which incurs a relatively high radiation dose. Despite patient selection a significant number have a normal barium examination. A prospective study was performed to evaluate the use of transabdominal ultrasound as(More)
Expanding metal oesophageal stents are being used more commonly to palliate patients with inoperable oesophageal carcinoma. Many reports have so far documented their clinical effectiveness, however, their high acquisition cost has caused on-going concern when compared with the cost of conventional therapies. We reviewed 64 consecutive patients with(More)
The value of colour flow Doppler ultrasound scanning in patients with suspected acute carpal scaphoid fracture has been examined. A prospective study of 78 patients with signs and symptoms of carpal scaphoid injury was undertaken over a period of 6 months. Both wrists of all patients were scanned within 12-72 h of injury. The radial artery and carpal(More)
