Anestesia na Pré-Eclâmpsia

JUSTIFICATIVA E OBJETIVOS: Embora a pré-eclâmpsia acometa pequena porcentagem da população obstétrica, ela é responsável por considerável morbidade e mortalidade maternas. Assim sendo, o controle anestésico adequado deste grupo de pacientes ainda hoje é um desafio para os anestesiologistas. Este artigo tem a finalidade de apresentar a fisiopatologia, o tratamento farmacológico e as opções anestésicas para o parto normal ou cirúrgico, em pacientes com pré-eclâmpsia. CONTEÚDO: Estão descritos a classificação e terminologia da hipertensão arterial induzida pela gestação, a fisiopatologia, as alterações nos diversos órgãos e sistemas, os princípios gerais no controle das pacientes e as opções anestésicas para o parto normal e cirúrgico. CONCLUSÕES: O conhecimento, pelo anestesiologista, da fisiopatologia, das formas de tratamento e das características farmacológicas das drogas utilizadas para o controle da hipertensão arterial e a profilaxia das convulsões, assim como sua interação com as drogas e técnicas anestésicas, possibilita a redução das complicações peri-operatórias e da mortalidade materna e fetal.

Factors associated with the prevalence of hypertension and control practices among elderly residents of São Paulo city, Brazil

The aim of this study was to analyze the prevalence of hypertension and control practices among the elderly. The survey analyzed data from 872 elderly people in São Paulo, Brazil, through a cluster sampling, stratified according to education and income. A Poisson multiple regression model checked for the existence of factors associated with hypertension. The prevalence of self-reported hypertension among the elderly was 46.9%. Variables associated with hypertension were self-rated health, alcohol consumption, gender, and hospitalization in the last year, regardless of age. The three most common measures taken to control hypertension, but only rarely, are oral medication, routine salt-free diet and physical activity. Lifestyle and socioeconomic status did not affect the practice of control, but knowledge about the importance of physical activity was higher among those older people with higher education and greater income. The research suggests that health policies that focus on primary care to encourage lifestyle changes among the elderly are necessary.

Sistemas cerámicos puros parte 1: una evolución basada en la composicíon

The continuing advances in technology, dental materials and equipment have contributed significantly to improve the level of esthetic dentistry today. Among these innovations, development of pure ceramic restorations has evolved to give different alternatives. Dental ceramics have presented a rapidly technological changing to improve mechanical and optical properties. Currently there are several systems of metal free ceramics with excellent mechanical and optical properties, for making crowns and plurals. These modern systems are presented with various compositions and different preparation techniques, making these more versatile. Within this perspective, the dental market offers a huge range of new indirect and metal-free materials for prostheses, providing new options, plus also new questions to decide among the available alternatives. The aim of this review is take a view of the different ceramic systems in terms of its composition and different techniques of production.

Avaliação das áreas de conflito de uso em APP da microbacia do alto água fria, Bofete (SP)

The misuse of land by man and is causing serious problems to the environment, resulting in ecological imbalance and depletion of natural resources, especially when it comes to areas of permanent preservation, that ecosystems are essential for balance and water conservation importance . Conflicts of land use is a major cause of silting of rivers and water bodies, causing significant losses in soil and decaying natural water resources both in quantity and in quality. Within this scenario, the planning becomes essential for the control of environmental impacts to the environment factor. This study aimed to evaluate land use conflicts in permanent preservation areas of the stream Água Fria watershed, Bofete (SP) using Geographic Information System and satellite image of LANDSAT - 5 of 2010, scale 1:50000. The results show that 51.16% of the permanent preservation areas of the watershed are conflicting, especially for pasture (88.94%) and reforestation with eucalyptus (11.06%). The GIS IDRISI Selva and Cartalinx along with GIS techniques demonstrated speed and efficiency in identifying, measuring and editing maps of land use, preservation and ongoing conflicts in areas of permanent preservation.
