RESUMO
Q fever, caused by Coxiella burnetii, is a poorly recognized zoonotic infection given its polymorphic clinical presentation. The diagnosis should not be missed to treat in the acute phase and thus prevent major complications of the chronic phase. We describe a case of acute Q fever with pancreatitis, hypereosinophilia and pulmonary infiltrates.
RESUMO
A follow-up prevalence study was done in 1989 of the same Kampuchean refugee population (247 subjects) that had been screened and treated for intestinal parasite infection 6 years earlier. A control group (102 subjects) included Kampuchean refugees who had arrived in Montreal at about the same time. These groups did not differ in age, sex, family size, or number of months spent in refugee camps. Statistically significant prevalence differences were observed in the rescreened group between 1982-1983 (63.7%) and 1989 (21.9%) and between the rescreened group and the control group (39.2%). These differences are largely attributable to the elimination of Ascaris infection and decreases in Giardia and hookworm infections. However, Strongyloides infection decreased only slightly (from 15% to 11%) in the rescreened group, while 12% of the control group was infected. Despite an early screening and treatment program, there remain important health risks in this immigrant population due to long-lived potentially pathogenic parasites.
