Background-Existing scales for assessing faecal incontinence have not been validated against clinical assessment, or with regard to reproducibility. They also fail to take into account faecal urgency, and the use of antidiarrhoeal medications. Aims-To establish the validity, and sensitivity to change, of existing scales and a newly designed incontinence scale. Methods-(1) Twenty three patients (21 females, median age 57 years) were prospectively evaluated by two independent clinical observers, using three established scales (Pescatori, Wexner, American Medical Systems), a newly devised scale which also includes details about urgency and antidiarrhoeal drugs, and by a 28 day diary. (2) A further 10 female patients were assessed by the same scales before and after surgery for faecal incontinence. (Gut 1999;44:77-80)

Background and aim: Evidence exists for the pathogenic role of the enteric flora in inflammatory bowel disease. Probiotics contain living microorganisms which exert health effects on the host. We compared the efficacy in maintaining remission of the probiotic preparation Escherichia coli Nissle 1917 and established therapy with mesalazine in patients with ulcerative colitis. Patients and methods: In total, 327 patients were recruited and assigned to a double blind, double dummy trial to receive either the probiotic drug 200 mg once daily (n = 162) or mesalazine 500 mg three times daily (n = 165). The study lasted for 12 months and patients were assessed by clinical and endoscopic activity indices (Rachmilewitz) as well as by histology. The primary aim of the study was to confirm equivalent efficacy of the two drugs in the prevention of relapses. Results: The per protocol analysis revealed relapses in 40/110 (36.4%) patients in the E coli Nissle 1917 group and 38/112 (33.9%) in the mesalazine group (significant equivalence p = 0.003). Subgroup analyses showed no differences between the treatment groups in terms of duration and localisation of disease or pretrial treatment. Safety profile and tolerability were very good for both groups and were not different. Conclusions: The probiotic drug E coli Nissle 1917 shows efficacy and safety in maintaining remission equivalent to the gold standard mesalazine in patients with ulcerative colitis. The effectiveness of probiotic treatment further underlines the pathogenetic significance of the enteric flora.
