Última Hepatitis in Dengue Shock Syndrome BJID Souza,Luiz José de; Carneiro,Helder Gonçalves; Souto Filho,João Tadeu Damian; Souza,Thiago Ferreira de; Côrtes,Vitor Azevedo; Gicovate Neto,Carlos; Bastos,Diogo Assed; Siqueira,Edno Wallace da Silva. Dengue fever is the most frequent arbovirus disease in the world and the most important one in terms of morbidity and mortality. Atypical manifestations of dengue have become commonplace during the last few years, including hepatic damage, which manifests mainly by pain in the right hypochondrium and an increase in the levels of aminotransferases. We describe a case of acute hepatitis in a patient with Dengue Shock Syndrome Grade III. We analyzed the clinical and laboratory aspects of this atypical complication of dengue as well as the differential diagnoses.

Junqueira; Paola,Angelo Amato Vincenzo de. Dengue fever is a viral infection transmitted by the mosquito, Aedes aegypti. Cardiac rhythm disorders, such as atrioventricular blocks and ventricular ectopic beats, appear during infection and are attributed to viral myocarditis. However, supraventricular arrhythmias have not been reported. We present a case of acute atrial fibrillation, with a rapid ventricular rate, successfully treated with intravenous amiodarone, in a 62-year-old man with dengue hemorrhagic fever, who had no structural heart disease.

Dengue is the most important disease caused by an arbovirus (1, 2, 3 and 4 serotypes) worldwide, especially in the tropical and sub-tropical regions. Its clinical manifestations range from asymptomatic infections to a severe disease characterized by hemorrhage and shock. The incidence of dengue virus activity in the Americas has substantially increased from 1980 to 1994. In Brazil, the increase in the incidence of dengue is especially linked to the dissemination of Aedes aegypti. Thus, a rapid and accurate dengue diagnosis is of paramount importance for effective control of dengue outbreaks [8]. Five serological tests have been used for the diagnosis of dengue infection: hemagglutination-inhibition (HI), complement fixation (CF), neutralization test (NT),...

Dengue fever is the world's most important viral hemorrhagic fever disease, the most geographically wide-spread of the arthropod-born viruses, and it causes a wide clinical spectrum of disease. We report a case of dengue hemorrhagic fever complicated by acute hepatitis. The initial picture of classical dengue fever was followed by painful liver enlargement, vomiting, hematemesis, epistaxis and diarrhea. Severe liver injury was detected by laboratory investigation, according to a syndromic surveillance protocol, expressed in a self-limiting pattern and the patient had a complete recovery. The serological tests for hepatitis and yellow fever viruses were negative. MAC-ELISA for dengue was positive.

PRADAARISMENDY,JEANETTE; CASTELLANOS,JAIME E. Las infecciones transmitidas por Flavivirus se encuentran entre las enfermedades transmisibles con mayor incidencia en el mundo. La mayoría de ellas se manifiestan clínicamente como un síndrome febril que puede estar o no acompañado de diversos síntomas. La severidad de estas infecciones es variable con casos asintomáticos y otros que pueden llegar a ser letales. La razón de esta variabilidad en la presentación clínica, se desconoce en humanos. En ratones se han identificado cepas susceptibles y cepas resistentes a la infección por algunos Flavivirus. Por clonación posicional se mapeó el gen responsable de la resistencia a virus West Nile en el cromosoma 5 de ratón y se identificó como oligoadenilato sintetasa 1b (Oas1b).

(Diptera: Culicidae) Neotropical Entomology Honório,Nildimar A.; Barros,Fábio S.M. de; Tsouris,Pantelis; Rosa-Freitas,Maria G.. Toxorhynchites guadeloupensis (Dyar & Knab), a poorly known mosquito species, was observed preying upon Aedes aegypti (L.) larvae, in an oviposition trap placed for routine dengue entomological surveillance, during 2003-2004 in the urban area of Boa Vista, Roraima, Brazil. This is the first report for Tx. guadeloupensis using Ae. aegypti oviposition traps as breeding places. This finding may have important consequences in the epidemiology and local dengue control since Ae. aegypti density is a basic variable in dengue prediction. Whether predation of Ae aegypti by Tx. guadeloupensis in the Amazon is of significance, is a question to be examined. Also, larval predation may be a cause for underestimation of the actual Ae aegypti numbers. Together...

Avaliou-se a abundância e agregação dos ovos de Aedes aegypti L. e Aedes albopictus Skuse em Cambé, Ibiporã, Jacarezinho, Maringá e Paranavaí, PR, utilizando-se armadilhas de oviposição. De 225 armadilhas instaladas, 100 registraram-se positivas para ovos. Coletaram-se 4140 ovos, demonstrando distribuição altamente agregada. Ambas as espécies foram encontradas em Cambé, Jacarezinho, Maringá e Paranavaí. Ae. albopictus não foi detectado em Ibiporã, porém onde esteve presente foi menos abundante. A relação entre sexos aproximou-se de 1:1, para Ae. aegypti. Na comparação dos números de adultos coletados entre as duas espécies, obteve-se correlação negativa nas amostras de Maringá e Cambé, o que foi atribuído à sazonalidade dessas populações.

For the development of safe live attenuated flavivirus vaccines one of the main properties to be established is viral replication. We have used real-time reverse transcriptase-polymerase chain reaction and virus titration by plaque assay to determine the replication of yellow fever 17DD virus (YFV 17DD) and recombinant yellow fever 17D viruses expressing envelope proteins of dengue virus serotypes 2 and 4 (17D-DENV-2 and 17D-DENV-4). Serum samples from rhesus monkeys inoculated with YFV 17DD and 17D-DENV chimeras by intracerebral or subcutaneous route were used to determine and compare the viremia induced by these viruses. Viral load quantification in samples from monkeys inoculated by either route with YFV 17DD virus suggested a restricted capability of...

Vaccination is the most practical and cost-effective strategy to prevent the majority of the flavivirus infection to which there is an available vaccine. However, vaccines based on attenuated virus can potentially promote collateral side effects and even rare fatal reactions. Given this scenario, the developent of alternative vaccination strategies such as DNA-based vaccines encoding specific flavivirus sequences are being considered. Endogenous cytoplasmic antigens, characteristically plasmid DNA-vaccine encoded, are mainly presented to the immune system through Major Histocompatibility Complex class I - MHC I molecules. The MHC I presentation via is mostly associated with a cellular cytotoxic response and often do not elicit a satisfactory humoral...

(Diptera: Culicidae) Neotropical Entomology Beserra,Eduardo B; Fernandes,Carlos R M; Sousa,José T de; Freitas,Eraldo M de; Santos,Keliana D. The present research aimed at evaluating the influence of the water quality in the life cycle and attraction of Aedes aegypti (L.) females to oviposit using different sources of water (raw sewage, effluent of UASB reactor, effluent of polishing lagoon, effluent of anaerobic filter, rain water and de-chlorinated water). The immature development time and survivorship were evaluated on a daily basis in two distinct feeding systems (with and without food). The quality of the water was shown to affect the egg and larval stages, but not the pupal or the adult. In the absence of food, no development was observed in rain water and de-chlorinated water. Immature development was faster in water sources from raw sewage, although with the lowest survivorship (37.3%)....

Bras. entomol. Costa,Ethiene Arruda Pedrosa de Almeida; Santos,Eloína Maria de Mendonça; Correia,Juliana Cavalcanti; Albuquerque,Cleide Maria Ribeiro de. In short space of time increase in temperature and rainfall can affect vector populations and, consequently, the diseases for them transmitted. The present study analyzed the effect of small temperature and humidity variations on the fecundity, fertility and survival of Aedes aegypti. These parameters were analyzed using individual females at temperatures ranging from 23 to 27 °C (mean 25 °C); 28 to 32 °C (mean 30 °C) and 33 to 37 °C (mean 35 ºC) associated to 60±8% and 80±6% relative humidity. Females responded to an increase in temperature by reducing egg production, oviposition time and changing oviposition patterns. At 25 ºC and 80% relative humidity, females survived two-fold more and produced 40% more eggs when compared to those kept at 35 ºC and 80%...

This study evaluates the importance of native bromeliads growing on rocky outcrops interspersed with urbanized areas as breeding sites for the Aedes aegypti (L.) in Vitória, state of Espírito Santo, Brazil. Oviposition traps were installed in backyards of houses in two separate zones. In the first zone houses were up to 50 m away from the rocky outcrops, while in the second zone they were at least at 200 m from the rocky outcrops. Aedes aegypti was significantly more abundant in the latter zone. The finding was that rocky outcrops with native bromeliads, even with the greater availability of potential breeding sites, do not play an important role as breeding sites for A. aegypti.
