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)
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)
— In this paper, a backward compatible header error protection mechanism is described. It consists of the addition of a dedicated marker segment to a JPEG 2000 codestream, that will contain the error correction data generated by a block error correction code (e.g. a Reed Solomon code). This mechanism allows to leave the original data intact, hence providing(More)
ALADDIN [1] is a multidisciplinary project that is developing novel techniques, architectures, and mechanisms for multi-agent systems in uncertain and dynamic environments. The application focus of the project is disaster management. Research within a number of themes is being pursued and this is considering different aspects of the interaction between(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)
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)
