The emergency regarding recent immigration waves into Italy makes continued healthcare monitoring of these populations necessary. ⋯ Our survey, through a combined analysis of both DRGs and discharge diagnoses, allowed us to conclude that 12.1% of foreign citizens hospitalized at our General teaching Hospital of Bologna (Italy) suffered from at least one infectious disease. Respiratory tract, liver, and gastrointestinal infections, and HIV infection, were found with an appreciable frequency among discharge diagnoses, while the frequency of malaria and meningoencephalitis was lower, compared with other series. Among disorders other than infectious diseases, obstetric-gynecological conditions and post-traumatic episodes (for male patients) were the most frequent causes of hospitalization.

Tuberculosis (TB)/HIV co-infection significantly changes the natural history of both diseases. Proper comprehension and clinical management of co-infected TB/HIV patients is still a challenge, particularly in places like Brazil, where both types of infection are prevalent. ⋯ The pulmonary forms of TB were most frequent in HIV infected patients; the extrapulmonary, associated and disseminated forms were predominantly seen in patients with a more severe level of immunosuppression. The TB recovery rate in HIV infected patients was similar to the expected rate in non-infected individuals. The best results were obtained when regimens containing rifampicin were used. Pancytopenia and low levels of TCD4+ and TCD8+ lymphocytes at the initial time point of the study were correlated with an unfavorable outcome of TB, and therefore they can be considered potential prognostic factors. However, the of TCD8+ lymphocyte values were the most important variable assessed.

Cutaneous manifestations in disseminated strongyloidiasis are infrequent but should raise the suspicion for its diagnosis. We retrospectively evaluated the charts of six patients with cancer and a proven diagnosis of disseminated strongyloidiasis. ⋯ Strongyloides larvae were identified in tracheal aspirates (n=5), gastric aspirates (n=4), lung (n=2) and skin biopsies (n=2). All patients died despite antihelminthic therapy and intensive care support.

Bloodstream infections caused by yeast, Candida spp, are quite important clinically and epidemiologically due to a high mortality rate and an increasing number of non-albicans species with a more resistant (differentiated susceptibility) profile. We examined species prevalence and susceptibility profile for fluconazole and the risk for nosocomial infections by Candida spp at the Hospital de Clínicas de Porto Alegre, a general tertiary care hospital in southern Brazilian, through a retrospective study, beginning with positive cultures of hospitalized patients. The distribution by species in 131 documented episodes was as follows: Candida albicans (45%), C. parapsilosis (24.4%), C. tropicalis (15.3%), C. glabrata (6.9%), C. krusei (4.6%) and 3.8% other species (C. pelicullosa, C. guilliermondii, C. lusitaniae and C. kefyr). ⋯ We found that C. albicans was the most prevalent species, although the non-albicans species predominated. However, in vitro resistance to fluconazole was detected only among the species (C. glabrata and C. krusei) that tend to be resistant to the azolic compounds. Previous use of antibiotic and the use of a central venous catheter were the main risk factors among patients with candidemia.

We studied an outbreak of two multi-drug resistant clones of Acinetobacter baumannii in the Neonatal Intensive Care Unit of the Uberlândia Federal University Hospital in Minas Gerais state, Brazil, and we analyzed the contribution of cross-transmission in the rise in infection rates. Eleven neonates who developed multi-drug resistant A. baumannii nosocomial infection were matched to 22 neonates who were admitted to the same unit and did not develop an infection during the outbreak period, in order to identify risk factors for infection. Three out of the 11 neonates died. ⋯ These factors were: exposure to antibiotics and invasive devices, birth weight < 1500 g, age < or = 7 days and duration of hospitalization > or = 7 days. Based on logistic regression, infected neonates were more exposed to carbapenem and mechanical ventilation than the control group. Cross transmission between infants contributed to the rise in the rates of multi-drug resistant A. baumannii infection.
