OBJETIVO:Revisar a literatura sobre estudos que estimaram a prevalência de pressão arterial elevada (PAE) ou hipertensão arterial sistêmica (HAS) em adolescentes brasileiros, considerando os procedimentos metodológicos empregados.MÉTODOS:Pesquisa bibliográfica de estudos de prevalência de PAE/HAS em adolescentes de 1995 a 2010. A busca foi realizada nas bases de dados eletrônicos PubMed/Medline, Lilacs, SciELO, Isi e Adolec. Foram utilizados os descritores: hipertensão, pressão arterial, adolescente, estudantes, estudos transversais, prevalência e Brasil, nas línguas portuguesa e inglesa. Além disso, foi elaborado um escore, baseado nas Recommendations for Blood Pressure Measurement in Humans and Experimental Animals e nas VI Diretrizes Brasileiras de Hipertensão, para a análise dos procedimentos utilizados para medida da PA nos estudos variando de 0 a 18.RESULTADOS:Foram identificados 21 artigos, a maioria publicada nos últimos 10 anos, sendo 90,5% realizados em base escolar e nas regiões sudeste, nordeste e sul do país. As prevalências de PAE/HAS variaram de 2,5 a 30,9%. A pontuação dos estudos variou de 0 a 16. Foi observada uma correlação negativa significante (rho = -0,504; p = 0,020) entre a prevalência de PAE/HAS e o escore da qualidade da medida da PA.CONCLUSÃO:A grande variabilidade das estimativas da PAE/HAS parece ser influenciada pelos procedimentos metodológicos utilizados nos estudos.

CONTEXTO:Abscessos isolados do tronco encefálico são raros e geralmente associados a outras infecções. Trata-se de condição grave, com grande morbidade e mortalidade. Opções cirúrgicas são aspiração com estereotaxia e drenagem microcirúrgica. Antibioticoterapia sistêmica tem sido usada por mais de seis semanas.RELATO DE CASO:Apresentamos o caso de um jovem com abscesso pontino sem outras infecções sistêmicas. O paciente foi tratado com drenagem microcirúrgica e antibioticoterapia por três semanas. Houve boa evolução pós-operatória.CONCLUSÕES:Acesso microcirúrgico pode ser considerado uma opção importante no tratamento de grandes abscessos do tronco encefálico, que são multiloculados, próximos da superfície ou que contenham líquido espesso. Drenagem completa do material purulento pode diminuir o período de antibioticoterapia.

The hemodynamic effects of total intravenous anesthesia with propofol or propofol in combination with lidocaine were investigated in 12 dogs. In the P group (n=6), the dogs received a loading dose (LD) of 6mg kg-1 of propofol followed by a constant rate infusion (CRI) of 1.25mg kg-1 min-1. In the PL group (n=6), dogs received a LD of 6mg kg-1 of propofol and 1.5mg kg-1 of lidocaine followed by CRIs of 1.0mg kg-1 min-1 and 0.25mg kg-1 min-1 of propofol and lidocaine, respectively. The animals were instrumented for measurement of hemodynamic variables and bispectral index (BIS), recorded at 75, 90, 105 and 120 minutes during anesthesia. Cardiac index, stroke index, systolic, diastolic and mean arterial blood pressures were lower in the P group compared to the PL group (P<0.05). There were no significant differences between groups in heart rate, systemic vascular resistance index and BIS. Plasma concentrations of propofol were lower in group PL than in group P (medians of 5.7 to 6.1mg mL-1 in the P group versus 3.1 to 3.7mg mL-1 in the PL group). Measured lidocaine plasma concentrations (medians of 2.27 to 2.51mg mL-1) were in the range that result in analgesia and were below values that result in toxicity in dogs. The BIS values observed in the two groups of dogs were compatible with deep anesthesia (mean values of 43-46 and 45-49 in groups P and PL, respectively). Maintenance of deep anesthesia with lidocaine-propofol causes less cardiovascular depression than equipotent doses of propofol alone.

Staphylococcus are not usually studied in the oral cavity, when this happens, they are considered to belong to transitory microflora. Individuals that present periodontal disease represent possibles reservoirs of these opportunist bacteria in the oral cavity. The use of antibiotics whether for treatment of periodontal disease or due to hospital infections, may predispose the increase of the Staphylococcus spp. in the oral cavity because they easily become resistant to antibiotics, resulting in superinfection. The study was made with 88 patients, minimum age- 25 years old, presenting chronical periodontitis, with, at least, two sites having a probing pocket bigger or equal to 5mm. After anamnese and clinical periodontal examination samples were taken from the periodontal pocket using paper cones and from the oral cavity using mouth rinse. Of the total patients 37,50% presented Staphylococcus spp. in the periodontal pocket and 61,36% in lhe oral cavity; 27,27% presented bacteria in the two sites, not necessarily of the same specie. S. epidermidis was the most prevailing specie in periodontal pocket (15,9%) and oral cavity (27,27%). Positive for S. aureus in the periodontal pocket were 4,5% and for the oral cavity 25%, and 3,4% were positive for the two sites. There was not found significative statistical difference referring to the presence of the microorganisms as to age, smoking habit and increase of the probing depth. The majority of the isolated Staphylococcus samples showed resistance to the tested antibiotics, indicating that the drugs as an adjunct to periodontal therapy, must be seen with caution

The objective of this paper is to introduce a model, called the Model of the System of Schemes of Actions and Operations on Symbols and Signs (MoSSAOSS), that articulates a systemic, systematic, and synthetic view of some of the principal theoretic and experimental results obtained by Piaget and his coworkers. Here, the term model means a schematic representation of experience, the relation of whose elements can be explored by means of logic and mathematics in order to deduce properties that correspond, in a sufficiently accurate form, to direct observable empirical properties. The MoSSAOSS model is intended to reveal in an abstract and simplified form, and through explicit hypothesis and definitions, the general structure and function of the System of Schemes of Actions and Operations on Symbols and Signs. It is this system that furnishes the elements that make possible the diverse structures necessary for the knowledge of the epistemic subject, the subject of knowledge, the stages in their construction, and the attribution of significations to objects, to situations, and to the actions and operations of the subject itself.

The global economic scenario, from the late 1980s, it was predominantly marked by the hegemony of political and economic orthodoxy. The strength of a great political pact that brought together the financial sector, rentiers and the big capital, and had the Washington Consensus as base, induced countries to adopt liberalizing policies such as trade liberalization, privatization and deregulation. The failure of these policies, manifested in unemployment, external vulnerability and low growth has led to a change in economic direction, particularly after the election of President Lula. Amid this situation, we can see a reorientation of the role of the Brazilian state, in response to a movement of their own society organized to implement a new national strategy, with the state as a promoter of development. In this project of a new strategy, the state action becomes strategic and not systemic, turning to strengthen national companies in strategic sectors and internationally competitive. In this ongoing process of a new development strategy, we adopted the conceptualization of what Bresser-Pereira calls the new developmentalism.
