Disodium cromoglycate in the treatment of ulcerative colitis and Crohn's disease.

A controlled clinical study on disodium cromoglycate (DSCG) at a dose of 800 mg per day versus placebo was carried out in 141 patients with ulcerative colitis and 25 patients with Crohn's disease. Those of the ulcerative colitis patients who had been on sulphasalazine treatment continued that treatment during the trial (101 patients). Forty patients were intolerant of sulphasalazine. No patient received steroids during the last month before the study. Patients with Crohn's disease had their possible sulphasalazine treatment stopped before the trial. No beneficial effect of DSCG as compared with placebo was found, as the DSCG and the placebo group showed the same number of relapses in patients with a clinically inactive ulcerative colitis at the start of the trial and the same number of patients improving, deteriorating, and maintaining steady state in patients with clinically active ulcerative colitis at the start of the trial. There was no difference between relapse rate in DSCG and placebo groups in patients with Crohn's disease. No correlation between the eosinophil count in rectal mucosa and the outcome of the attack of ulcerative colitis could be demonstrated.

Ethical aspects of clinical decision-making.

The aim of the present investigation was to describe and to classify significant ethical problems encountered by the members of the staff during the daily clinical work at a hospital medical department. A set of definitions was prepared for the purpose, including the definition of a 'significant ethical problem'. During a three month period 426 inpatients and 173 outpatients were admitted. Significant ethical problems were encountered during the management of 106 in-patients (25 per cent) and 9 out-patients (5 per cent). No significant difference was found between the frequency of ethical problems in female and male patients, but a positive correlation was noted between the number of problems and the patients' age. The problem types were classified according to a problem list. The results of this investigation suggest that greater attention must be paid to discussions about ethical problems among doctors and other categories of health personnel and that, among others, medical students ought to be taught the analysis of ethical problems.

Dynamic sonography in the evaluation of jaundice.

The value of dynamic sonography as a screening procedure in 84 jaundiced patients was examined and compared with the clinical evaluation of a blind prospective study. The predictive value of the sonographic diagnosis of obstruction was 97% and 84% in nonobstruction. The corresponding values of the clinical distinction were 87% and 92% respectively. The level of obstruction was demonstrated in 95% and the cause of obstruction was diagnosed in 68%. When the cause of jaundice is uncertain or obstruction is suspected clinically, dynamic sonography can offer high diagnostic accuracy and guidance for invasive investigations.

Recurrence of duodenal ulcer pain after treatment with cimetidine for four and eight weeks.

This double-blind controlled trial compares the relapse rate in 19 duodenal ulcer patients who received cimetidine for eight weeks with that in 19 patients who received cimetidine for four weeks and inactive tablets for four weeks. Only patients who became symptom-free during the initial four weeks' treatment with cimetidine were included. The median period of remission after withdrawal of cimetidine was 50 days in patients treated with cimetidine for eight weeks and 76 days in patients treated with cimetidine for four weeks (P greater than 0.10). Six months after withdrawal of cimetidine 15 relapses had occurred in both groups. It is concluded that patients who become symptom-free during four weeks' cimetidine treatment do not benefit by continuation of treatment for another four weeks.

A comparative study of the protein pattern in serum and synovial fluid.

A routine program for evaluation of the protein pattern in serum and synovial fluid has been tested on 25 patients in a consecutive study. The program comprised agar gel electrophoresis, total protein and albumin determination, and immunochemical determination of antitrypsin, orosomucoid, haptoglobin, IgR, and IgA. Linear correlation analysis of corresponding data in serum and synovial fluid gave r-values for the five latter components which varied from 0.74 to 0.87. On this basis reference intervals in synovial fluid could be established. Total protein, haptoglobin and IgG were elevated in rheumatoid arthritis, compared with osteoarthritis.
