[practices, knowledge and attitudes about human hydatidosis in peru].	between july 2005 and june 2006, a case-control study was carried out to identify risk factors for hydatidosis in lima, peru. as a result, 32 cases were matched according to age, sex and birthplace in 64 controls. the participants were interviewed using a questionnaire designed to evaluate environmental and behavior factors associated to hydatidosis. by using multiple conditional logistic regression, it was determined that the owners of >or=10 dogs in a rural area (aor=8.7; 95% cl=1.3-57.5) and ...	2008	18418456
identification of risk factors for cystic echinococcosis in a peri-urban population of peru.	we conducted a questionnaire-based case-control study to identify risk factors for cystic echinococcosis (ce) in lima, peru during july-december 2005. data were obtained from 32 cases and 64 controls. multivariate conditional logistic regression showed that having owned > or =10 dogs [adjusted odds ratio (aor) 8.7, 95% ci 1.3-57.5) and raising sheep (aor 5.9, 95% ci 1.2-28.1) were independently associated with ce. the belief that ce could be transmitted by food (aor 0.1, 95% ci 0.01-0.7) and bre ...	2008	17949765
