Abstract: one hundred and thirty cases of diarrhea and 43 age-matched controls, 0 to 5 years old, were studied in a pediatric outpatient unit from a poor peri urban area of porto velho, rond?nia. eighty percent of diarrheal cases were observed in the groups under 2 years of age. rotavirus (19.2%) was the most frequent enteropathogen associated with diarrhea, followed by shigella flexneri (6.15%) and s. sonnei (1.5%) and salmonella sp. (6.9%). four cases of e. coli enterotoxigenic infections (3.1%), e. coli enteropathogenic (epec)(2.3%) one case of e. coli enteroinvasive infection (0.8%) and one case of yersinia enterocolitica (0.8%) were also identified. mixed infections were frequent, associating rotavirus, epec and salmonella sp. with entamoeba histolytica and giardia lamblia.

Abstract: in rond?nia state, brazil, two new hydroelectric plants, santo ant?nio and jirau, are scheduled for construction on the madeira river, upriver from the state capital, porto velho. the current study analyzes malaria prevalence before the construction and provides information on the possible impacts of malaria burden related to the influx of thousands of persons attracted by direct and indirect employment opportunities. according to the findings, malaria is present throughout the region, with varying prevalence rates. the existence of potential asymptomatic malaria carriers among the local population may be epidemiologically relevant and should be considered in the malaria control programs organized by public authorities and companies responsible for building the power plants, aimed at early diagnosis and treatment, vector control, water supply, and infrastructure in the urban areas.

Abstract: objective: to predict readmission in intensive care unit analyzing the first 24 hours data after intensive care unit admission. methods: the first intensive care unit admission of patients was analyzed from january to may 2009 in a mixed unit. readmission to the unit was considered those during the same hospital stay or within 3 months after intensive care unit discharge. deaths during the first admission were excluded. demographic data, use of mechanical ventilation, and report of stay longer than 3 days were submitted to uni and multivariate analysis for readmission. results: five hundred seventy-seven patients were included (33 excluded deaths). the readmission group had 59 patients, while 518 patients were not readmitted. the lead time between the index admission and readmission was 9 (3-28) days (18 were readmitted in less than 3 days), and 10 died. patients readmitted at least once to the intensive care unit had the differences below in comparison to the control group: older age: 75 (67-81) versus 67 (56-78) years, p<0.01; admission for respiratory insufficiency or sepsis: 33 versus 13%, p<0.01; medical admission: 49 versus 32%, p<0.05; higher saps ii score: 27 (21-35) versus 23 (18-29) points, p<0.01; charlson index: 2 (1-2) versus 1 (0-2) points, p<0.01; first icu stay longer than 3 days: 35 versus 23%, p<0.01. after logistic regression, higher age, charlson index and admission for respiratory and sepsis were independently associated to readmissions in intensive care unit. conclusion: age, comorbidities and respiratory- and/or sepsis-related admission are associated with increased readmission risk in the studied sample.

Abstract: the emerging world order of intellectual properly protection while creating new and stricter multilateral rules for technology transfer, presents several challenges to developing countries. besides the burden of new additional payments of royalties from the south, it also would point to a restraint in the free flow of scientific and technological information from the north, perhaps a new kind of " technological apartheid". developing countries should start from within the adjustment the new order, probably by means of regional programs of technological cooperation, which southern latin-american countries are the best qualified to perform in the framework of the mercosul integration process.

Abstract: starting from the congress of vienna, in which only eight "christian" states assisted, through the hague peace conferences and the versailles treaty, mobilizing no more than two dozens countries, to the current uno system, virtually universal, international society has undergone a deep democratization in the last two centuries, even if the sources of political and economic power and its distribution among countries have been substantially maintained. this process of enlargement of the old "restrictive democracy" is mostly evident in the institutional rule making for the international economic relations, where multilateral organizations for technical and economic cooperation - among them the imf, the world bank and the wto - have a significant role in reinforcing the global interdependence among states. this historical essay follows the evolution of multilateralism, in the longue durée, with particular attention to its economic features, and examines brazil's international insertion in the world economy, as one of the few "peripheric" countries which took an active part in the making of "international economic order". indeed, brazil was present at the creation of most, if not all, intergovernmental organizations and took part in various multilateral conferences from the 19 th century to our times.
