Comparison of polyethylene glycol versus combination of magnesium sulphate and bisacodyl for colon preparation.

Colon preparation using polyethylene glycol (PEGLEC) and combination of bisacodyl and magnesium sulphate was compared in 74 patients. Type of preparation did not influence patient discomfort. The quality of preparation was excellent with PEGLEC in 63.6% as compared to 41.6% with combination preparation. The completion rates were similar in both groups. Good preparation was linked with shorter procedure duration (p = 0.001) and greater depth of examination. No major side effects were noted with both preparations. To conclude, polyethylene glycol is recommended for screening of right colon while combination of bisacodyl and magnesium sulphate is a good and cheap preparation modality to screen the left colon.

Role of pinaverium bromide in south Indian patients with irritable bowel syndrome.

The effect of pinaverium bromide in controlling gastrointestinal symptoms in 61 patients with irritable bowel syndrome was studied, as an open trial. Individually, there was significant relief in abdominal discomfort/pain as well as in bowel symptoms in most of the patients. Abdominal pain was reduced in 49%, stool consistency improved in 74%, straining and urgency decreased in 71% and mucus decreased in 64%. Tolerance to the drug administered was good and side-effects reported were few.

Is vegetarianism a precipitating factor for gallstones in cirrhotics?

AIM: To study the association of factors such as alcohol, smoking and vegetarianism with presence of gallstones amongst cirrhotics. PATIENTS AND METHODS: Data on alcoholism, smoking and vegetarianism was collected from the case records of 669 cirrhotics with (76) or without gallstones (593) retrospectively. Relative risk for the factors was computed individually and in combination controlling for the effects of alcoholism and smoking on vegetarianism. RESULTS: Alcoholism and smoking were of low relative risk [R.R-1.27 (95% CI 0.82 to 1.96), and 1.02 (95% CI 0.65 to 1.61) respectively] while vegetarianism was associated with high risk for gallstone formation in cirrhotics [R.R 2.74 (95% CI 1.65-4.53)]. Vegetarian men had a relative risk of 3.02 (95% CI 1.75-5.22) irrespective of their alcoholic status. If women were alcoholic the relative risk increased to 7.03 (95% CI 3.26-15.12). Controlling for effects of gender and alcoholism, vegetarian cirrhotics had a 3 times greater risk for gallstone formation [Mantel Haenszel Relative Risk 3.18 (95% CI MHRR 1.82-5.56)]. CONCLUSIONS: Cirrhotic, vegetarian women in South India have a much higher risk for gallstones, if they are alcoholic. Alcoholic men who are vegetarians are at a greater risk for gallstone disease.
