The underlying diagnosis and clinical course of 52 patients who presented with severe acute gastrointestinal haemorrhage while taking the anticoagulant warfarin is reviewed. A bleeding site was identified in 83% of cases, only slightly fewer than the 92% found in a control of group of 710 patients not taking warfarin who presented in the same four year(More)
Between 1973 and 1983 abdominal tuberculosis was responsible for the admission of 90 patients to a west London district general hospital. Over the same period Crohn's disease was newly diagnosed in 102 hospitalised patients. In contrast with Crohn's disease, the majority (75) of tuberculous patients were Asian immigrants. Mean duration of residence in the(More)
Research in multimedia learning lacks an emphasis on individual difference variables, such as working memory capacity (WMC). The effects of WMC and the segmentation of multimedia instruction were examined by assessing the recall and application of low (n = 66) and high (n = 67) working memory capacity students randomly assigned to either a segmented(More)
Mucosal cell proliferation in the first part of the duodenum was studied in 24 patients using a tissue culture technique in which endoscopic biopsies were subjected to autoradiography after exposure to tritiated thymidine. Eight patients had a normal duodenum, eight had duodenal ulcer, and eight had symptomatic chronic non-specific duodenitis. The mean(More)
One hundred and twenty patients presenting with major peptic ulcer haemorrhage were randomised in a clinical trial comparing endoscopic injection and heater probe therapy. The two groups were well matched with regards to age, admission haemoglobin concentration, the presence of shock, non-steroidal anti-inflammatory drug usage and endoscopic findings.(More)
The efficacy and safety of mono-octanoin, a cholesterol solvent for the direct dissolution of stones in the biliary tract, was assessed by collating case reports on 343 patients provided by 222 physicians who used the material between 1977 and 1983. Most patients had previously undergone cholecystectomy, with common duct exploration, the majority within the(More)
A patient undergoing repeated endoscopic injection therapy for important bleeding from a duodenal ulcer developed intestinal perforation followed by extrahepatic obstructive jaundice resulting from benign biliary stricture. It is proposed that these complications were a consequence of the use of ethanolamine oleate as part of the injection regimen and(More)
