RESUMO
We studied the effect of dietary factors and a variety of other risk factors on the development of cholelithiasis through a case control study. The study involved 96 cases and 118 age and sex matched controls. All cases and controls were interviewed with regard to a variety of risk factors and frequency of consumption of over 100 food items. Analysis was done both by chi square and a multiple logistic regression model. From all the dietary factors the only ones that showed a positive statistically significantly (p less than 0.05) association was consumption of animal fat as expressed by eating all visible fat on the meat and using butter on the table. Interestingly high consumption of olive oil had a negative (protective) association with the disease. A negative association was also found with smoking and holding a job demanding hard labor.

The possibility of an association between rheumatoid arthritis (RA) and prior tonsillectomy and appendectomy was investigated in a community based case-control study of 229 female cases of probable and definite RA and 458 appropriately matched controls. No association was found with logistic analysis even when controlling for a variety of factors such as socio-economic status, oral contraceptive use, and their interactions.
