Detecção de metalo-beta-lactamase em Pseudomonas aeruginosa isoladas de pacientes hospitalizados em Goiânia, Estado de Goiás

Pseudomonas aeruginosa é uma bactéria frequentemente isolada no ambiente hospitalar. Este estudo teve como objetivo avaliar o perfil de suscetibilidade de Pseudomonas aeruginosa previamente isoladas de pacientes internados em um hospital de Goiânia (Goiás-Brasil); realizar a triagem fenotípica para a produção de metalo-beta-lactamase e detectar os genes das mesmas pela técnica de "Polimerase Chain Reaction". Foram avaliadas 75 Pseudomonas aeruginosa isoladas no período de janeiro de 2005 a janeiro de 2007. A identificação bioquímica foi realizada pelo sistema API 20E® e o antibiograma pelo método de Kirby-Bauer. Entre os 62 isolados que foram resistentes ao imipenem e à ceftazidima, 35 (56,4%) apresentaram produção de metalo-beta-lactamase e em 26 (74,3%) destes, foi detectado o gene blaSPM-1. A frequência de Pseudomonas aeruginosa produtoras de metalo-beta-lactamase sugere um maior controle da disseminação de resistência no ambiente hospitalar.

Antimicrobial susceptibilities of Listeria monocytogenes human strains isolated from 1970 to 2008 in Brazil

INTRODUCTION: Listeria monocytogenes is the causative agent of listeriosis, a foodborne illness that affects mainly pregnant women, the elderly and immunocompromised patients. The primary treatment is a combination of ampicillin with an aminoglycoside, in addition to a second-choice drug represented by chloramphenicol, erythromycin, tetracycline and rifampicin. The aim of this study was to analyze the antimicrobial susceptibility profile of strains isolated from human sources in the last four decades. METHODS: Sixty-eight strains were selected from the culture collection of the Laboratory of Bacterial Zoonoses/LABZOO/FIOCRUZ isolated in different regions of Brazil from 1970 to 2008 and primarily isolated from cerebrospinal fluid and blood culture. Susceptibility tests to antimicrobials drugs were evaluated using the criteria established by Soussy using the Kirby-Bauer method and E-Test strips were used to determine the minimum inhibitory concentration (MIC). RESULTS: Among the strains tested, serovar L4b (60.3%) was the most prevalent, followed by serovar 1/2a (20.6%), 1/2b (13.2%) and the more uncommon serovars 1/2c, 3b and 4ab (5.9%). All strains were susceptible to ampicillin, cephalothin, erythromycin, gentamicin, teicoplanin and vancomycin. Only one strain (1.5%) showed resistance to rifampin, and two (3%) were resistant to trimethoprim-sulfamethoxazole. MICs with values up to 2μg/ml reinforce the need for microbiological surveillance. CONCLUSIONS: The study demonstrated low prevalence of strains resistant to the antimicrobial drugs indicated in the treatment of human listeriosis. Monitoring antimicrobial resistance profile is still very important to determine adequate treatment, especially in immunocompromised patients.

Perfil clínico-epidemiológico dos casos de tétano acidental ocorridos em Ribeirão Preto, Estado de São Paulo, no período de 1990 a 2009

INTRODUÇÃO: O tétano continua sendo um grave problema de saúde pública nos países em desenvolvimento. No Brasil, apesar dos avanços tecnológicos, não houve um decréscimo significativo da taxa de letalidade nos últimos anos. Nesta casuística, foram analisados dados clínicos e epidemiológicos dos pacientes diagnosticados em Ribeirão Preto, nas últimas duas décadas. MÉTODOS: Este é um estudo retrospectivo que analisou dados dos pacientes internados por tétano acidental no Hospital das Clínicas de Ribeirão Preto, entre 1990 e 2009. O diagnóstico do tétano foi realizado segundo critérios do Ministério da Saúde do Brasil. RESULTADOS: Onze (47,8%), casos positivos, dos 23 suspeitos de tétano, foram incluídos neste estudo. Não houve mortes, mas dois (18,2%) pacientes apresentaram déficit neurológico permanente. O indicador prognóstico Tetanus Severity Score variou entre 0 a 8 pontos. A mediana da permanência hospitalar foi de 17 dias, variando de 6 a 98 dias. A ausência de óbitos pode ser explicada pelo diagnóstico clinico precoce da doença com instituição imediata de terapia. CONCLUSÕES: Ribeirão Preto é uma área onde o tétano não é um relevante problema de saúde pública.

Dipodascus capitatus (Geotrichum capitatum): infecção sistêmica fatal em paciente com leucemia mielocítica aguda

As infecções causadas por Dipodascus capitatus são raras e de difícil tratamento. Aqui se relata um caso em paciente com leucemia mielocítica aguda. O isolamento fúngico ocorreu a partir de hemocultura e a identificação fenotípica baseou-se em métodos micológicos clássicos; a identificação genotípica foi realizada através do sequenciamento da região D1/D2 do 26 rDNA. Os testes de suscetibilidade foram realizados através do Etest® e microdiluição em caldo. A antifungicoterapia foi ineficaz, registrando-se óbito da paciente no 17° dia após o diagnóstico. Os autores comparam o caso com relatos similares e discutem a emergência destas infecções bem como suas dificuldades diagnósticas e terapêuticas.

Histoplasmosis in immunocompetent individuals living in an endemic area in the Brazilian Southeast

Introduction The distribution of infection by Histoplasma capsulatum in Brazil is heterogeneous, and the number of cases affecting immunocompetent individuals is relatively small. This study reports the epidemiological and clinical data regarding histoplasmosis in non-immunosuppressed individuals. Methods The study included only the immunocompetent patients with histoplasmosis who were diagnosed between 1970 and 2012 at a university hospital located in Ribeirão Preto, State of São Paulo, Brazil. Clinical and epidemiological data were collected retrospectively from the patient records. Results Of the 123 patients analyzed, 95 had an active disease that manifested in the different clinical forms of histoplasmosis. Men were the predominant gender, and most patients resided in the Northeast of the State of São Paulo and in the nearby municipalities of the State of Minas Gerais. The risk factors for acquiring histoplasmosis and prolonged contact in a rural environment were recorded in 43.9% and 82.9% of cases, respectively. Smoking, alcoholism, and comorbidity rates were high among the patients with the chronic pulmonary and subacute/chronic disseminated forms of histoplasmosis. Many patients achieved clinical cure spontaneously, but 58.9% required antifungals; the disease lethality rate was 5.3%. Conclusions Immunocompetent individuals manifested the diverse clinical forms of histoplasmosis over a period of 4 decades, revealing an additional endemic area of this fungal disease in the Brazilian Southeast.

First report of yellow fever virus in non-human primates in the State of Parana, Brazil

Sylvatic yellow fever is a zoonosis associated mainly with wild animals, especially those in the genus Alouatta, that act as the source of infection. Once infected, these animals pass the disease on to humans by way of an infected mosquito belonging to the genera Aedes, Haemagogus, or Sabethes. The present study is the first report of a case of yellow fever in non-human primates (NHP) in the State of Paraná, Brazil. After the case was diagnosed, several prophylactic measures were adopted to prevent outbreaks of the disease in humans.

Semantics bias in cross-national comparative analyses : Is it good or bad to have "fair" health?

The Health Behavior in School-aged Children is a cross-national study collecting data on social and health indicators on adolescents in 43 countries. The study provides comparable data on health behaviors and health outcomes through the use of a common protocol, which have been a back bone of the study sine its initiation in 1983. Recent years, researchers within the study have noticed a questionable comparability on the widely used item on self-rated health. One of the four response categories to the item "Would you say your health is….?" showed particular variation, as the response category "Fair" varied from 20 % in Latvia and Moldova to 3-4 % in Bulgaria and Macedonia. A qualitative mini-survey of the back-translations showed that the response category "Fair" had a negative slant in 25 countries, a positive slant in 10 countries and was considered neutral in 9 countries. This finding indicates that there are what may be called semantic issues affecting comparability in international studies, since the same original word (in an English original) is interpreted differently across countries and cultures. The paper test and discuss a few possible explanations to this, however, only leaving to future studies to hold a cautious approach to international comparisons if working with the self-rated health item with four response categories.

Interaction of an opportunistic fungus Purpureocillium lilacinum with human macrophages and dendritic cells

IntroductionPurpureocillium lilacinum is emerging as a causal agent of hyalohyphomycosis that is refractory to antifungal drugs; however, the pathogenic mechanisms underlying P. lilacinum infection are not understood. In this study, we investigated the interaction of P. lilacinum conidia with human macrophages and dendritic cells in vitro.MethodsSpores of a P. lilacinum clinical isolate were obtained by chill-heat shock. Mononuclear cells were isolated from eight healthy individuals. Monocytes were separated by cold aggregation and differentiated into macrophages by incubation for 7 to 10 days at 37°C or into dendritic cells by the addition of the cytokines human granulocyte-macrophage colony stimulating factor and interleukin-4. Conidial suspension was added to the human cells at 1:1, 2:1, and 5:1 (conidia:cells) ratios for 1h, 6h, and 24h, and the infection was evaluated by Giemsa staining and light microscopy.ResultsAfter 1h interaction, P. lilacinum conidia were internalized by human cells and after 6h contact, some conidia became inflated. After 24h interaction, the conidia produced germ tubes and hyphae, leading to the disruption of macrophage and dendritic cell membranes. The infection rate analyzed after 6h incubation of P. lilacinumconidia with cells at 2:1 and 1:1 ratios was 76.5% and 25.5%, respectively, for macrophages and 54.3% and 19.5%, respectively, for cultured dendritic cells.ConclusionsP. lilacinum conidia are capable of infecting and destroying both macrophages and dendritic cells, clearly demonstrating the ability of this pathogenic fungus to invade human phagocytic cells.

Assessment of schistosomiasis in the semi-arid Northeast region of Brazil: the São Francisco River large-scale water transposition project

Abstract: INTRODUCTION Risk of schistosomiasis expansion to semi-arid northeastern Brazil under the influence of the Integration Project of the São Francisco River (IPSFR) was assessed. METHODS: Stool examinations of schoolchildren, epidemiological investigation, and survey of the local host snail Biomphalaria straminea were performed in five IPSFR municipalities. RESULTS Six of 4,770 examined schoolchildren were egg-positive for Schistosoma mansoni. Biomphalaria straminea was widespread, but not naturally infected with S. mansoni. Snails experimentally exposed to two laboratory S. mansoni strains yielded infection indices of 1-4.5%. CONCLUSIONS: There is evidence of active schistosomiasis transmission in the area; thus, intensive surveillance actions are required.

Induction of experimental mammary carcinogenesis in rats with 7,12-dimethylbenz(a)anthracene

PURPOSE: To test an experimental model of chemical mammary carcinogenesis induction in rats. METHODS: Twenty young virgin Sprague-Dawley female rats, aged 47 days, received 20 mg of 7,12-dimethylbenz(a)anthracene (DMBA) intragastrically by gavage. Afterwards, at 8 and 13 weeks, their mammary glands were examined. At the end of the experiment, the animals were sacrificed, and the mammary tumors were measured and weighed. Tumor fragments were analyzed using light microscopy. RESULTS: Eight weeks after DMBA injection, 16 rats presented at least 1 breast tumor (80%). After 13 weeks, all of them (100%) developed breast carcinomas that were confirmed by histopathological analysis. CONCLUSION: This experimental animal model of chemical mammary induced carcinogenesis is feasible and can be used in further experiments on the role of tumorigenic biomodulator substances.

A utilidade da aprendizagem criativa na aula de língua estrangeira

Este relatório surge no âmbito da minha Prática do Ensino Supervisionada e representa uma reflexão sobre a minha iniciação como professora de Inglês e de Francês no 3º ciclo do Ensino Básico e no Ensino Secundário. A reflexão teve como objeto o conceito de ‘aprendizagem criativa’ na teoria do ensino da língua estrangeira e a sua aplicação na prática letiva, nas duas escolas onde desenvolvi o meu estágio, a Escola Secundária de Sebastião da Gama e a Escola Básica do 2º e 3º Ciclos de Aranguez, ambas em Setúbal. Para além de uma tentativa de sistematização das abordagens teóricos, de modo a tornar a noção de ‘criatividade’ mais aplicável na prática da docência da língua estrangeira, a nossa reflexão procura evidenciar como e em que situações a aprendizagem se revela criativa e demonstra a sua utilidade para a aula de língua estrangeira.
