Scoring system to improve cost effectiveness of open access endoscopy.

The introduction of an open access general practitioner endoscopy service may result in many unnecessary examinations being performed. In an attempt to prevent this, 235 patients attending for endoscopy were interviewed and the results analysed to determine which factors best discriminated between those with major disease (ulcers, cancers, oesophageal strictures; n = 48) and those without (n = 187). The six characteristics which best discriminated between the two groups were increasing age, history of vomiting, male sex, smoking, and a past history of peptic ulcer or hiatus hernia. With the use of these six features a scoring system was devised, designed to give an indication of the likelihood of finding such disease in an individual patient. This was assessed prospectively in a further 356 patients. The results showed that by utilising this scoring system it would be possible to reduce the number of examinations performed by 30% yet still detect 98% of serious disease. If confirmed in further prospective studies, this scoring system (or a modification) could more accurately assess individual priority for endoscopy and enable optimum use to be made of limited resources.

Symptoms of irritable bowel syndrome in ulcerative colitis in remission.

The prevalence of symptoms suggestive of a motility disturbance similar to the irritable bowel syndrome was investigated in 98 patients with ulcerative colitis in remission, and a similar number of age- and sex-matched healthy controls. Thirty-three per cent of patients compared with 7% of controls fulfilled the criteria for such a syndrome (p<0.01). Contrary to expectations these symptoms were not confined to patients with distal disease. Other symptoms such as constipation were also very common in the colitic group (31%).

Factors preceding relapse of ulcerative colitis.

The effect of intercurrent diarrhoea on relapse of ulcerative colitis was investigated. Diarrhoea resulting from travel abroad, gastroenteritis or antibiotic usage resulted in an approximately 50% relapse rate. With regard to colonoscopy and barium enema, only the latter was followed by relapse and this may reflect differences in the preparation for the procedure.

Brucellar spondylodiscitis: MRI diagnosis.

Early diagnosis of brucellar spondylodiscitis is often difficult because of the long latent period. Radiographs of the spine, bone scan, and computed tomography (CT) scan provide insufficient data. Among 25 patients with brucellar spondylodiscitis studied by magnetic resonance imaging (MRI), 9 were in the acute stage and 16 were in the chronic stage. MRI is the investigation method of choice in diagnosing brucellar spondylodiscitis.

MRI findings of hepatic alveolar echinococcosis.

Diagnosis of liver infestation by alveolar echinococcosis (AE) is based on serologic, sonographic and computed tomography (CT) findings. Experience with magnetic resonance imaging (MRI) demonstrates that features of this disease are limited. CT and MRI findings of 14 cases with hepatic AE were compared in this report. We have described the MRI appearance of hepatic AE, which exhibits variable signal intensities on T1- and T2-weighted images. Fibrous and parasitic tissue showed low signal both on T1- and, generally, on T2-weighted images. In a few cases, a high signal on T2-weighted images may be observed, due either to central necrotic zones or to small peripheral cyst. MRI than by CT was more easily identified central necrosis. However, MRI seemed to be less effective than CT in allowing us to reach a positive diagnosis, due to its inability to show microcalcifications. In addition, MRI may not reveal small lesions. In most cases, T1-weighted images revealed more clearly than CT did the margins of the lesions and the hepatic extension, especially to hepatic veins, vena cava and perihepatic spaces.
