A 13-year departmental sample of 34 patients with definite (biopsy-verified) giant cell arteritis (GCA) was reviewed. The mortality of this material was compared to sex-, age- and time-specific death rates in the Danish population. The standardized mortality ratio (SMR) was 1.8 (95% confidence limits, 1.1-2.8). During the same period 146 patients with probable (not biopsied, but clinically diagnosed in the department) GCA and 85 cases of possible (diagnosed and treated before admission) GCA had been admitted to the department. Those two groups did not differ from the biopsy-verified group with respect to SMR, sex distribution or age. In the group of patients with department-diagnosed GCA (definite + probable = 180 patients), the 95% confidence interval for the SMR of the women included 1.0. In all other subgroups there was a significant excess mortality. Excess mortality has been found in two of seven previous studies on survival in GCA. The prevailing opinion that steroid-treated GCA does not affect the life expectancy of patients is probably not correct.

A group of outpatients with chronic non-organic upper abdominal pain was followed up 5-7 years after the index investigation, to evaluate the predictive value of several variables on the basis of a questionnaire and a laboratory pain study. Fifty-four per cent had symptoms of irritable bowel syndrome. A low pain tolerance measured with an ischemic pain technique significantly predicted a poor course of the disease (P = 0.03). So did a high score indicating psychic vulnerability (P = 0.02) and two social factors: poor school and vocational education (P less than 0.01). Without significant predictive value were level of abdominal pain rated on a visual analogue scale, length of dyspepsia history, bowel habits, relation of pain to meals and to life events, heartburn, headache, back pain, dysmenorrhea, paresthesias in fingers or feet, present occupation, sex, marital status, days absent from work because of the disease, and consumption of tranquilizers, cigarettes, and alcohol. The findings indicate that psychologic factors and a low pain tolerance may be elements in this poorly understood syndrome. This is supported by earlier findings of a decreased pain tolerance and an elevated psychologic score in this group compared with controls.

In a prospective study, the clinicopathological effect of prednisolone was evaluated in six patients with collagenous colitis. Prednisolone was associated with a significant decrease in stool frequency. However, the effect was transitory, since the diarrhoea recurred when prednisolone treatment was discontinued. There was a trend toward a diminished inflammatory response in the post-treatment biopsies, but the thickness of the collagen band remained unchanged, except in one patient. Until the results of further studies are available, we recommend that treatment with prednisolone be restricted to periods of acute diarrhoeal episodes.

To establish the diagnostic safety and the prognosis in outpatients with non-organic upper abdominal pain, 37 patients were followed up 5-7 years after the index investigation. In only one case had the diagnosis been changed during the follow-up period. This was in a man who erroneously had not been examined sufficiently before entry. He turned out to have gallstones. Eighty-one per cent still had abdominal pain, but 51% had improved (P less than 0.005). At the index investigation back pain was reported by 76% and headache by 60%. At the follow-up study back pain was unchanged in severity, but headache was significantly improved. The course of abdominal pain was significantly correlated with the course of back pain and headache. At the index investigation a psychic symptom score indicating vulnerability was significantly higher than in a matched patient group with well-defined pain. It was unchanged high at the follow-up study and unrelated to the course of the abdominal pain. Fifty-four per cent of the patients had symptoms of irritable bowel syndrome, but the course of the abdominal pain was unrelated to this.
