RESUMO
The DRESS (drug rash with eosinophilia and systemic symptoms) syndrome is a serious condition that has been reported in association with various drugs, such as allopurinol, sulfonamides and aromatic anticonvulsants. Recently the condition has been described in HIV-infected patients taking antiretroviral agents. We report the first case, to our knowledge, of DRESS syndrome complicated by meningoencephalitis associated with nevirapine therapy.

With the settlement of increasing numbers of immigrants from tropical African countries into Italy over the last decade, the epidemiologic pattern of imported malaria underwent significant change. Italian immigrants originating from endemic areas who revisit their country of origin have exhibited an increasing incidence of malaria: the Italian Ministry of Health recorded an increase of from 14% in 1986 to 40.4% in 1991. This retrospective study reviews the epidemiology of all malaria cases recorded from 1988 to 1991 in a regional reference center in North Eastern Italy. Epidemiologic factors, including the details of their travel experience, were examined for all cases, and the relation of immigrants to Italian-born citizens were compared. Of the 100 cases recorded during this period, 36 were diagnosed in 1988-1989 and 64 in 1990-1991. Immigrants accounted for six times more cases during the latter than during the former time period. Compared to nonimmune short-term travelers, immigrants experienced significantly milder forms of the disease and lower levels of parasitemia (Plasmodium falciparum) on admission. Notably, 10 cases of malaria in immigrants were not recognized at first observation on microbiology. With the advent of this new risk group of immigrants that originate from endemic countries, especially those making occasional short visits to their native countries, this new epidemiologic profile of malaria imported into Italy shows the need for improvement in the areas of prophylaxis, pretravel education, and diagnostic services.
RESUMO
In an investigation of a nosocomial outbreak of tuberculosis, 18 HIV-infected inpatients were found to have been exposed to Mycobacterium tuberculosis; active tuberculosis developed in 8, 7 within 60 days of diagnosis of the index case. The patients with lower total lymphocyte and CD4 lymphocyte counts were more likely to get the disease than were those with higher counts. A low score on multiple antigen skin testing was also associated with the development of active tuberculosis. 4 of the 18 patients had a positive tuberculin skin test before exposure to M tuberculosis; none of them subsequently got the disease.
