Aseptic meningitis in a large MMR vaccine campaign (590,609 people) in Curitiba, Paraná, Brazil, 1998

The aseptic meningitis after Measles-Mumps-Rubella vaccine (MMR) is a well recognized complication, and different incidences have been observed in several studies. We retrospectively analyzed forty cases of aseptic meningitis, during a large public immunization campaign (1998) in Curitiba, Southern Brazil (590,609 people), admitted in our Service. The vaccine utilized was Leningrad-3-Zagreb mumps strain, Edmonston-Zagreb measles strain, and RA 27#3 rubella strain. In all county, a total number of 87 cases were reported, resulting in a incidence of 1.7 cases per 10,000 given doses . The mean age was 23.7 ± 12.8 years. The female:male ratio was 1.35:1. Severe headache with meningismus (92.5%), fever (87.5%), nausea/vomiting (82.5%) were the most common clinical findings. Three cases (7.5%) developed mild mumps. All patients underwent cerebrospinal fluid (CSF) tap with the following findings: mononuclear pleocytosis from 100 to 500 cells/mm³ in 17 cases (42.5%; 257.5 ± 260.6 cells/mm³); increased protein 28 cases (67.5%; 92.1 ± 76.9 mg/dL); glucose was normal in all cases (56.8 ± 11.2 mg/dL) except in 4 (10%) cases, which presented less than 44 mg/dL. All serological tests (latex to bacterial meningitis, Cryptococcus, cysticercosis, VDRL) and bacteriological cultures were negative. Virus identification were also negative in 8 samples. None of the patients had neurological deficits or related symptoms after one year of onset. We believe the benefit of vaccination clearly outweights the incidence of benign vaccine-associated meningitis.

Diversidade de culturas organizacionais: obstáculos e desafios para a liderança de um mega agrupamento

Este projeto tem por base um problema identificado num mega agrupamento de um concelho do grande porto, criado em junho de 2012, e que se centra nas dificuldades de gestão e liderança de uma organização resultante da agregação de duas unidades com culturas organizacionais distintas. Na perspetiva de conhecermos e compreendermos o problema e respondermos ao nosso questionamento, optamos por uma metodologia qualitativa seguindo o método de um estudo de caso. No estudo empírico, cuja técnica de recolha foi um focus group, recolheram-se as perceções dos professores das unidades agregadas sobre a criação da nova organização, sobre o impacto nas identidades e culturas organizacionais, sobre a forma da procura de uma coesão no respeito pela diversidade e identificaram-se os quadros de referência das escolas que se agregaram. O estudo realizado permite reconhecer que as dificuldades ao nível da gestão e liderança se confinam mais na escola que perdeu a centralidade e que se sente numa posição periférica. Na elaboração do plano de ação recuperámos e valorizámos a ideia de que um modelo de liderança baseado em valores poderia ser um caminho para a unidade. Neste sentido o plano de ação, com base em alguns princípios de atuação e definição de estratégias tenta dar resposta à questão de partida e em congruência com um modelo de liderança por valores.

Can the complex mixture of sediment contaminants cause endocrine disruption on a benthic fish? A case study with Solea senegalensis

Pollution in coastal ecosystems is a serious threat to the biota and human populations there residing. Anthropogenic activities in these ecosystems are the main cause of contamination by endocrine disruption compounds (EDCs), which can interfere with hormonal regulation and cause adverse effects to growth, stress response and reproduction. Although the chemical nature of many EDCs is unknown, it is believed that most are organic contaminants. Under an environmental risk assessment for a contaminated estuary (the Sado, SW Portugal), the present work intended to detect endocrine disruption in a flatsfish, Solea senegalensis Kaup, 1858, and its potential relationship to organic toxicants. Animals were collected from two areas in the estuary with distinct influences (industrial and rural) and from an external reference area. To evaluate endocrine disruption, hepatic vitellogenin (VTG) concentrations in males and gonad histology were analysed. As biomarkers of exposure to organic contaminants, cytochrome P450 (CYP1A) induction and the ethoxyresorufin-O-deethylase (EROD) activity were determined. The results were contrasted to sediment contamination levels, which are overall considered low, although the area presents a complex mixture of toxicants. Either males or females were found sexually immature and showed no significant evidence of degenerative pathologies. However, hepatic VTG concentrations in males from the industrial area in estuary were superior than those from the Reference, even reaching levels comparable to those in females, which may indicate an oestrogenic effect resulting from the complex contaminant mixture. These individuals also presented higher levels of CYP1A induction and EROD activity, which is consistent with contamination by organic substances. The combination of the results suggest that the exposure of flatfish to an environment contaminated by mixed toxicants, even at low levels, may cause endocrine disruption, therefore affecting populations, which implies the need for further research in identification of potential EDCs, their sources and risks at ecosystem scale.

Mycetoma fungal infection: multiple organisms as colonizers or pathogens?

We describe a patient with mycetoma or Madura foot, in which histopathological stains of the bone and surface cultures suggested three different organisms including Nocardia species as the cause. Criteria for the diagnosis of the organisms, differentiation between colonizer and pathogen, and significance of mixed infections are discussed.

Epidemiological factors related to the transmission risk of Trypanosoma cruzi in a Quilombola community, State of Mato Grosso do Sul, Brazil

INTRODUCTION: This work was an epidemiological investigation of the risk of Trypanosoma cruzi transmission in the rural Quilombola community of Furnas do Dionízio, State of Mato Grosso do Sul, Brazil. METHODS: Of the 71 animals examined, seven were captured (two opossums, Didelphis albiventris; four rats, Rattus rattus; and one nine-banded armadillo, Dasypus novemcinctus) and 64 were domestic (one canine, Canis familiaris; five pigs, Sus scrofa; two bovines, Bos taurus; five caprines, Capra sp.; and 51 ovines, Ovis aries). Parasitological tests were performed to detect parasites in the blood and to identify the morphology of flagellates. These methods included fresh examinations, buffy coat tests and blood cultures. Molecular analysis of DNA for identification of trypanosomatids was performed by polymerase chain reaction (PCR) with primers S35 and S36. RESULTS: The parasitological tests showed flagellates in an opossum and two cattle. The molecular tests showed DNA from T. cruzi in an opossum and a pig. Triatoma sordida was the only triatomine species found in the community, and it colonized households (four specimens) and the surrounding areas (124 specimens). Twenty-three specimens tested positive for flagellates, which were subsequently identified as T. cruzi by PCR. CONCLUSIONS: Data analysis demonstrated that T. cruzi has a peridomestic life cycle that involves both domestic and wild mammals.

Análise comparativa da designação, definição e classificação de resíduos hospitalares em legislações da União Europeia

RESUMO - O quadro legislativo de um país, no que concerne aos resíduos hospitalares (RH), contém a sua designação, definição e classificação. É essa a matriz de referência para a separação efectuada na origem e todo o circuito que, a partir desse momento, um determinado resíduo toma até ao seu tratamento. Assim, faz-se o estudo comparativo das definições e tipos de classificação de RH em quatro países da União Europeia: Alemanha, Reino Unido, Espanha (Região Autónoma da Catalunha) e Portugal. Reconhecem-se as diferentes designações deste tipo de resíduos e discute-se o seu significado e as suas implicações na percepção de risco por parte dos profissionais e do público. Identificam-se duas estratégias subjacentes à elaboração das definições: a contaminação de materiais com microrganismos patogénicos bem definidos, as suas fontes e as actividades que os produzem. Apresentam-se as classificações de RH propostas pelos organismos internacionais de referência e analisa-se comparativamente a evolução do enquadramento legal português e da Região Autónoma da Catalunha, evidenciando-se a variabilidade temporal e justificando-se a necessidade de se efectuar o estudo da variabilidade geográfica. Utilizam-se três critérios para a análise das classificações consideradas: a concordância definição-classificação, o número e tipo de grupos das classificações e os tipos de resíduos por grupos. Identificam-se os denominadores comuns às classificações analisadas, assim como as suas principais diferenças. Conclui-se que a definição de RH adoptada por cada país condiciona o tipo de classificação de RH nesse mesmo país. Verifica-se ainda que a inexistência de critérios claros de avaliação da contaminação pode dificultar a tarefa da triagem dos RH por parte dos profissionais de saúde.

Development of ductile cementitiuos composites using carbon nanotubes

Concrete is the primary construction material for civil infrastructures and generally consists of cement, coarse aggregates, sand, admixtures and water. Cementitious materials are characterized by quasi-brittle behaviour and susceptible to cracking [1]. The cracking process within concrete begins with isolated nano-cracks, which then conjoin to form micro-cracks and in turn macro-cracks. Formation and growth of cracks lead to loss of mechanical performance with time and also make concrete accessible to water and other degrading agents such as CO2, chlorides, sulfates, etc. leading to strength loss and corrosion of steel rebars. To improve brittleness of concrete, reinforcements such as polymeric as well as glass and carbon fibers have been used and microfibers improved the mechanical properties significantly by delaying (but could not stop) the transformation of micro-cracks into macro forms [2]. This fact encouraged the use of nano-sized fillers in concrete to prevent the growth of nano-cracks transforming in to micro and macro forms. Nanoparticles like SiO2, Fe2O3, and TiO2 led to considerable improvement in mechanical performance and moreover, nano-TiO2 helped to remove organic pollutants from concrete surfaces [3].
