In a population-based case-control study of pancreatic cancer in Greater Montreal between 1984 and 1988, a total of 24 patients with cancer of the bile ducts and 33 patients suffering from cancer of the gallbladder were compared to 239 population-based controls. This study was part of the SEARCH program of the International Agency for Research on Cancer. In cases of cancer of the bile ducts, smoking nonfiltered cigarettes produced a relative risk of 2.82 and a 95% confidence interval of 1.01-7.86 after adjustment for age, sex, other smoking habits, alcohol consumption, schooling, and respondent status. Laxative intake was associated with a risk of 2.87 (1.00-8.22). Coffee drinkers were collectively at lower risk than non-drinkers: OR = 0.26 (0.07-0.95). In patients with cancer of the gallbladder, constipation was related to a risk of 3.19 (1.02-9.95) after adjustment for the same factors. In cases with previous gallbladder problems, the risk was found to be significant [OR = 7.96 (2.03-31.2)], 8 times greater in cases than in controls.

Laxatives and the production of autacoids by rat colon.

Capasso F, Mascolo N, Autore G, Romano V.

The effects of some laxatives were examined on the formation of histamine, 5-hydroxytryptamine (5-HT) and prostaglandin-like material (PG-LM) by rat intestine in-vitro. Castor oil, senna, sulphosuccinate and bisacodyl, but not mannitol or lactulose, in doses that cause laxation, increased the formation of histamine, 5-HT and PG-LM. Indomethacin or hydrocortisone reduced the increase of PG-LM formation. The data support the idea that the laxative effects of these intestinal secretagogues are due to increased intestinal production of PG-LM, histamine and 5-HT.

Straining at stool and laxative taking in an English population.

Heaton KW, Cripps HA.

Department of Medicine, University of Bristol, England.

A population-based sample of 834 men (ages 40-69 years) and 1058 women (25-29 years) was investigated with respect to straining to defecate, stool form, bowel habit, and use of laxatives, by means of a questionnaire and a three-stool record form. Straining was common but, contrary to standard teaching, far from universal. It was unrelated to age but was commoner in women than men. Many people underestimated how often they strained. Overall, 32% of defecations in women and 22% of defecations in men were associated with straining to start and 15% and 9%, respectively, with straining to finish. Straining was to some extent related to stool type: the lumpier a stool, the more often it elicited straining. However, it seems likely that straining in some people is just a habit. Use of laxatives was found to be less prevalent than in the past, and most people with evidence of constipation did not use them. Use of laxatives increased with age, and some older people used them inappropriately. The most popular laxatives were based on phenolphthalein, senna, or magnesium.
