Plano para Enfermeiros Orientadores de Alunos em Estágio

O presente artigo tem o intuito de dar a conhecer um plano, destinado a enfermeiros que colaboram na supervisão de alunos de enfermagem em estágio, identificando algumas linhas orientadoras, de modo organizado e sistematizado, que visam a melhoria dos processos formativos. Deste modo pretende-se despertar os orientadores para algumas situações e considerações que poderão ser significativas, no sentido de facilitar o processo de ensino-aprendizagem de todos os seus intervenientes.

Dengue in an elderly patient

Although elderly populations are more exposed to the risk of getting dengue, the clinical peculiarities of this disease in this age range are not well known. This report is about an 80-year-old woman with dengue complications, self-medicated with salicylate. Literature indicates a more severe clinical condition, high hospitalization rate and significant mortality. This is caused by previous infections by other serotypes of this arbovirus, presence of chronic diseases, immunosenescence and high drug consumption, especially salicylates and the like. Analyses are required in a public health perspective in order to help health professionals that care for patients with dengue in this age range.

Syndromic surveillance: etiologic study of acute febrile illness in dengue suspicious cases with negative serology. Brazil, Federal District, 2008

With the aim of identifying the etiology of acute febrile illness in patients suspected of having dengue, yet with non reagent serum, a descriptive study was conducted with 144 people using secondary serum samples collected during convalescence. The study was conducted between January and May of 2008. All the exams were re-tested for dengue, which was confirmed in 11.8% (n = 17); the samples that remained negative for dengue (n = 127) were tested for rubella, with 3.9% (n = 5) positive results. Among those non reactive for rubella (n = 122), tests were made for leptospirosis and hantavirus. Positive tests for leptospirosis were 13.9% (n = 17) and none for hantavirus. Non reactive results (70.8%) were considered as Indefinite Febrile Illness (IFI). Low schooling was statistically associated with dengue, rubella and leptospirosis (p = 0.009), dyspnea was statistically associated with dengue and leptospirosis (p = 0.012), and exanthem/petechia with dengue and rubella (p = 0.001). Among those with leptospirosis, activities in empty or vacant lots showed statistical association with the disease (p = 0.013). Syndromic surveillance was shown to be an important tool in the etiologic identification of IFI in the Federal District of Brazil.

Avaliação institucional e melhoria: o trajeto do plano de melhoria de um agrupamento de escolas

No decurso deste projeto, procurou-se através do desenvolvimento de um processo de investigação-ação, efetuar mudanças em dois níveis, tendo sido o primeiro em prol da minoração de debilidades na aprendizagem previamente diagnosticadas num Agrupamento de Escolas, e o segundo visando uma transformação de hábitos enraizados, inerentes à cultura organizacional da comunidade escolar que compõe este Agrupamento. Desta forma, pretendeu-se a compreensão de determinadas situações que se constituíam, na aceção do investigador, como problemáticas sob determinados aspetos e suscetíveis de mudança, exigindo uma resposta prática. Face a isto, procurou-se construir um projeto realista porém ambicioso, assente em lógicas e teorias validadas e enquadrado nas especificidades de um Agrupamento de Escolas. Ao longo do trajeto, recorreu-se a uma série de procedimentos, designadamente de investigação, planeamento, ação, negociação, mudança, monitorização, análise e reformulação. Espera-se e deseja-se que os procedimentos levados a termo surtam os efeitos para os quais foram delineados e que perdurem, particularmente, na cultura organizacional que integra o Agrupamento, embora ciente que as mudanças efetivas nem sempre se produzem em espaços temporais definidos à partida.

Acute inflammatory demyelinating polyradiculoneuropathy (Guillain-Barré syndrome) following dengue fever

This paper reports a case of dengue in a six-year-old female child who suddenly developed excruciating headaches, fever, myalgia and paresis. Laboratory examinations included blood count, platelet count, biochemical tests (BUN, creatinine, aminotransferases, and total bilirubin and bilirubin fractions) and specific IgM titers (enzyme-immunoassay with recombinant tetravalent dengue). After ten days of hospitalization and having already been in a home environment, a new clinical image emerged, characterized by dysphagia, dysphonia, weakness, peripheral facial palsy and paresthesia. The diagnosis of Guillain-Barré Syndrome was based on clinical findings, cerebrospinal fluid examination, electrophysiological findings and the exclusion of other pathologies. Our case, as some shown in previous reports, calls attention to the possibility that Guillain-Barré Syndrome may occur in association with dengue.

Evaluation of dengue NS1 antigen detection for diagnosis in public health laboratories, São Paulo State, 2009

The present work evaluated the diagnostic accuracy of detection of Dengue NS1 antigen employing two NS1 assays, an immunochromatographic assay and ELISA, in the diagnostic routine of Public Health laboratories. The results obtained with NS1 assay were compared with virus isolation and, in a subpopulation of cases, they were compared with the IgM-ELISA results obtained with convalescent samples. A total of 2,321 sera samples were analyzed by one of two NS1 techniques from March to October 2009. The samples were divided into five groups: groups I, II and III included samples tested by NS1 and virus isolation, and groups IV and V included patients with a first sample tested by NS1 and a second sample tested by IgM-ELISA. Sensitivity, specificity, positive and negative predictive values, Kappa Index and Kappa Concordance were calculated. The results showed that NS1 testing in groups I, II and III had high sensitivity (98.0%, 99.5% and 99.3%), and predictive values and Kappa index between 0.9 - 1.0. Groups IV and V only had Kappa Concordance calculated, since the samples were analyzed according to the presence of NS1 antigen or IgM antibody. Concordance of 92.1% was observed when comparing the results of NS1-negative samples with IgM-ELISA. Based on the findings, it is possible to suggest that the tests for NS1 detection may be important tools for monitoring the introduction and spread of Dengue serotypes.

Co-infection of Dengue virus by serotypes 3 and 4 in patients from Amazonas, Brazil

The natural co-infection with dengue virus can occur in highly endemic areas where different serotypes have been observed for many years. We report here four cases of DENV-3/DENV-4 co-infection detected by serological and molecular tests among 674 patients with acute undifferentiated fever from the tropical medicine reference center of Manaus City, Brazil, between 2005 and 2010. Analysis of the sequences obtained indicated the presence of genotype 3 and 1 for DENV-3 and DENV-4 respectively.

First isolation of dengue 4 in the state of São Paulo, Brazil, 2011

We report the first isolation of Dengue virus 4 (DENV-4) in the state of São Paulo, from two patients - one living in São José do Rio Preto and the other one in Paulo de Faria, both cities located in the Northwest region of the state. The virus isolations were accomplished in the clone C6/36 Aedes albopictus cell line, followed by indirect immunofluorescence assays, performed with type-specific monoclonal antibodies that showed positive reactions for DENV-4. The results were confirmed by Nested RT-PCR and Real-Time RT-PCR assays. The introduction of DENV-4 in a country that already has to deal with the transmission of three other serotypes increases the possibility of the occurrence of more severe cases of the disease. The importance of early detection of dengue cases, before the virus spreads and major outbreaks occur, should be emphasized.
