25. Perfil clínico-epidemiológico da dengue em menores de 15 anos de idade, no município de Goiânia Goiás. / Clinical and epidemiological profile of dengue fever in children under 15 years old, in Goiânia Goiás
No Brasil, a dengue esta presente em quase todos os estados e territórios, com circulação de três sorotipos diferentes (DEN 1, DEN 2 e DEN 3), resultando em cerca de 500 mil casos notificados, em 2007 (PAHO 2008; MS/SVS 2008a). A presente dissertação de mestrado é composta por uma revisão da literatura, com ênfase na epidemiologia da dengue no Brasi

26. Aedes aegypti, Aedes albopictus, and dengue in Argentina: current knowledge and future directions
Since the reinfestation of South American countries by Ae. aegypti, dengue fever (DF) and dengue hemorrhagic fever (DHF) have become a major public health concern. The aim of this paper was to review the information related with Aedes vectors and dengue in Argentina since the reintroduction of Ae. aegypti in 1986. The geographic distribution of Ae. albopictu

27. The dynamics of dengue virus serotype 3 introduction and dispersion in the state of Bahia, Brazil
By 2002, dengue virus serotype 1 (DENV-1) and DENV-2 had circulated for more than a decade in Brazil. In 2002, the introduction of DENV-3 in the state of Bahia produced a massive epidemic and the first cases of dengue hemorrhagic fever. Based on the standardized frequency, timing and location of viral isolations by the state's Central Laboratory, DENV-3 prob

28. Association of insecticide use and alteration on Aedes aegypti susceptibility status
Dengue and dengue hemorrhagic fever, vector-borne diseases transmitted by the mosquito Aedes aegypti, are presently important public health problems in Brazil. As the strategy for disease control is based on vector control through the use of insecticides, the development of resistance is a threat to programs efficacy. The objective of this study was to compa

29. Histopathological and ultrastructural aspects of mice lungs experimentally infected with dengue virus serotype 2
Histological and ultrastructural alterations in lung tissue of BALB/c mice infected with dengue virus serotype 2 (non-neuroadapted), by intraperitoneal and intravenous routes were analyzed. Lung tissues were processed following the standard techniques for photonic and electron transmission microscopies. Histopathological and ultrastructural studies showed in

30. The health and economic impact of dengue in Latin America
In the last two decades, all countries in the tropical regions of Latin America have experienced marked increases in the incidence of both classic dengue and dengue hemorrhagic fever. Major risk factors for the occurrence of dengue in the region, as well as some regional peculiarities in its clinical expression, such as the extensive involvement of older age

31. Temporal distribution of dengue virus serotypes in Colombian endemic area and dengue incidence: re-introduction of dengue-3 associated to mild febrile illness and primary infection
We have investigated the temporal distribution of dengue (DEN) virus serotypes in the department (state) of Santander, Colombia, in relation to dengue incidence, infection pattern, and severity of disease. Viral isolation was attended on a total of 1452 acute serum samples collected each week from 1998 to 2004. The infection pattern was evaluated in 596 labo

32. Activated peripheral lymphocytes with increased expression of cell adhesion molecules and cytotoxic markers are associated with dengue fever disease
The immune mechanisms involved in dengue fever and dengue hemorrhagic/dengue shock syndrome are not well understood. The ex vivo activation status of immune cells during the dengue disease in patients was examined. CD4and CD8 T cells were reduced during the acute phase. Interestingly, CD8 T cells co-expressing activation marker HLA-DR, Q, P, and cytolytic gr

33. CaracterizaÃÃo genÃtica de isolados virais da dengue
A caracterizaÃÃo molecular do vÃrus da dengue à Ãtil na determinaÃÃo da origem de amostras e, principalmente, na tentativa de se estabelecer uma correlaÃÃo de virulÃncia dos isolados e sua importÃncia epidemiolÃgica. Embora os quatro sorotipos do vÃrus da dengue possam causar a febre hemorrÃgica da dengue considerando a infecÃÃo primÃria, al

34. Seleção e caracterização de peptídeos recombinantes miméticos de antígenos do vírus da dengue por "PHAGE DISPLAY"
Dengue fever is caused by an arbovirus of the Flaviridae family, transmitted from person to another through an intermediate fly vector, Aedes aegypti. It is a tropical and subtropical infectious disease characterized by fever and strong pain in joints, which could also lead to bleeding in its hemorrhagic form. In this investigation, Phage Display technology

35. Pathologic study of a fatal case of dengue-3 virus infection in Rio de Janeiro, Brazil
Dengue hemorrhagic fever (DHF) is a severe febrile disease, characterized by abnormalities in hemostasis and increased vascular permeability, which in some cases results in hypovolemic shock syndrome and in dengue shock syndrome. The clinical features of DHF include plasma leakage, bleeding tendency and liver involvement. We studied the histopathological fea

36. Molecular epidemiology of type 1 and 2 dengue viruses in Brazil from 1988 to 2001
Dengue is a mosquito-borne viral infection that in recent decades has become a major international public health concern. Epidemic dengue fever reemerged in Brazil in 1981. Since 1990 more than one dengue virus serotype has been circulating in this tropical country and increasing rates of dengue hemorrhagic fever and dengue shock syndrome have been detected
