Educa??o social de rua: bases históricas, políticas e pedagógicas
Oliveira, Walter Ferreira de;
História, Ciências, Saúde-Manguinhos , 2007, DOI: 10.1590/S0104-59702007000100007
Abstract: this work is about street social education as a pedagogical system that started in latin america in the late 1970s, as the street population formed mostly by children and adolescents called for attention. the first street social educators were 'pastoral' agents working at the pra?a da sé, a place with large numbers of street children in s?o paulo. based on the liberation theology and on the pedagogies developed by paulo freire, celestine freinet, anton makarenko, and emília ferreiro, the street educators developed a conceptual field and participated in the promulgation of the 1988 federal constitution, particularly by writing and introducing the 'estatuto da crian?a e do adolescente' (the 'child and adolescent statute'). street social education is currently latent and suffering the consequences of program discontinuity caused by successive changes of government. it is, therefore important to know the conceptual proposals.
Violência e Saúde Coletiva: contribui??es teóricas das ciências sociais à discuss?o sobre o desvio
Oliveira, Walter Ferreira de;
Saúde e Sociedade , 2008, DOI: 10.1590/S0104-12902008000300006
Abstract: public health and the human and social sciences are inseparable fields of knowledge, as attested by a tradition of research groups and research lines located in public health post-graduate programs. several difficulties have been pointed when discussions about various themes traditionally identified with the social sciences, as is the case of violence, are inserted in the health field. at the same time, such discussions are considered essential to the understanding of the determination of populations' health conditions and quality of life. the discussion focus regarding this phenomenon lacks theoretical contributions from other disciplines, such as sociology, whose theories on crime and deviance constitute an important benchmark in the study of the various forms of violence. in this article, the author examines the classic sociological theories in this area, aiming to contribute to the expansion of discussion in the field of public health, particularly in terms of a knowledge base to be applied to health promotion, crime prevention and rehabilitation, thus considering public health from an interdisciplinary, intersectorial perspective.

Abstract: Objetivou-se identificar elementos tóxicos presentes nos seguintes produtos intensivamente utilizados na agropecuária brasileira: fosfato bicálcico, fosfato supertriplo, fosfato supersimples, fosfato monoam nico, fosfosulfato de am nio, polifosfato de cálcio e am nio, sal mineral bovino artesanal, farinha de ossos e calcário. Para a detec o dos elementos tóxicos utilizou-se as técnicas de difratometria de raios-x, absor o at mica de forno de grafite, colorimetria, gravimetria e ativa o neutr nica. Foram detectados diversos elementos tóxicos, assim classificados conforme a agência norte americana de registro de substancias tóxicas e doen a relacionadas - ATSDR (Agency for Toxic Substances and Disease Registry) como alumínio, arsênio, bário, cério, césio, cobalto, flúor, estr ncio, tório, uranio, vanádio e zinco . Também foram observadas elevadas concentra es de silício na forma de quartzo na farinha de ossos e no sal mineral bovino. O fosfato bicálcico é o produto que apresenta a menor presen a de elementos tóxicos. Summary: This study aimed to identify toxic elements present in products largely used in Brazilian agriculture and livestock: dicalcium phosphate, super-triple phosphate, super-simple phosphate, monoammonium phosphate, sulphur amonium phoshphate, ammoniated calcium polyphosphate, a farm-made bovine mineral supplement, a bone meal and a limestone. Many techniques were employed in such analyses: X-ray diffractometry, atomic absorption, colorimetric and gravimetric techniques and instrumental neutron activation. It was detected many elements classified as hazard and toxic elements by the (United States) ASTDR - Agency for Toxic Substances and Disease Registry such as Al, As, Ba, Ce, Cs, Co, F, Sr, Th, U, V e Zn. It has also noted a high presence of Si as quartz in the bone meal and in the bovine mineral supplement. Bicalcic phosphate presents the smallest presence of hazardous elements.

Descartáveis urbanos: discutindo a complexidade da popula??o de rua e o desafio para políticas de saúde
Varanda, Walter;Adorno, Rubens de Camargo Ferreira;
Saúde e Sociedade , 2004, DOI: 10.1590/S0104-12902004000100007
Abstract: the adult homelessness is focused in the scope of the health and of social intervention intending to set up subsidies to the implementation of health public policies to this population. the conceptualization of this population and its relation with social exclusion, the city, the underground economies, globalization, strategies and the survival circuits, are inserted in a context of opposition to the social mechanisms that put them apart from society and breaks the family links. it is also related to institutional practices. the precariousness and unhealthiness from the streets results in a cumulative vulnerability which demands intervention and treatment according to a specific health condition, challenging the general concepts of universal access, integrality and equity of national health policies.
Terapia comunitária: prática relatada pelos profissionais da rede SUS de Santa Catarina, Brasil
Padilha, Cristina dos Santos;Oliveira, Walter Ferreira de;
Interface - Comunica??o, Saúde, Educa??o , 2012, DOI: 10.1590/S1414-32832012005000044
Abstract: the aim of this exploratory and descriptive study was to describe the community therapy practices reported by 27 healthcare professionals within the brazilian national health system (sus), in santa catarina, brazil. the data were gathered through individual semi-directed interviews, and content analysis was used for categorical themes. the results were grouped into five categories: community therapy practices; implementation strategies; difficulties; facilitative elements; and benefits. it was concluded that community therapy can contribute towards construction of expanded clinical action and improved value for territory resources. however, community therapists' actions need to be extended to a multidisciplinary team, have dialogue with other entities, receive support from service management and be allied to other public policies, in order to expand their field of action from healthcare to other sectors.

Ayala, Arlene Laurenti Monterrosa;Oliveira, Walter Ferreira de;
Trabalho, Educa??o e Saúde , 2007, DOI: 10.1590/S1981-77462007000200003
Abstract: this study is based on a critical analysis of work management in the public health sector in joinville (state of santa catarina), with regards to the daily work situation of health care workers in the basic unified national health system (sus) units. it identifies a few of the health service's operating principles, as set forth by the management such as work domination mechanisms, and which result from its division, as follows: the fragmentary nature of work organization in the health sector, management's conflict domination, worker control by production goals, and health care worker resistance to imposed workloads. the study uses the following research techniques to show the work division: interviews and direct observation of the work.
Laboratory diagnosis of Chagas' heart disease
Ferreira, Antonio Walter;ávila, Sandra do Lago Moraes de;
Sao Paulo Medical Journal , 1995, DOI: 10.1590/S1516-31801995000200006
Abstract: the laboratory diagnosis of chagas' disease is a complex one. factors relating to the host immune response and the antigenic variability of t. cruzi must be considered in the final interpretation of test results. parasitologic methods for detecting t. cruzi, immunologic methods for detecting t. cruzi antigens in different biological fluids and serologic tests for detection and quantification of different classes of immunoglobulins are well standardized and used in the diagnosis of the acute or chronic phase of the disease. xenodiagnosis is the most common parasitologic test employed, although it detects only 50% of infections in the chronic phase. indirect immunofluorescence for detecting igg and igm antibodies, hemagglutination and enzyme immunoassay are the serologic tests most frequently employed for diagnosis, to screen blood donors and for seroepidemiologic studies. an important caveat to be remembered is that serologic tests provide only a probable diagnosis, which depends on the prevalence of chagas disease, as well as on the sensitivity and specificity of the test employed. the use of well defined specific antigens, obtained through recombinant methods or chromatography, opens an important field for the development of very specific tests, without significant loss of sensitivity.
Observa??es sobre o TESA blot no diagnóstico sorológico da doen?a de Chagas
Amato Neto, Vicente;De Marchi, Cláudia Regina;Ferreira, Cláudio Santos;Ferreira, Antonio Walter;
Revista da Sociedade Brasileira de Medicina Tropical , 2005, DOI: 10.1590/S0037-86822005000600019
Abstract: tesa blot was compared with indirect hemagglutination, indirect immunofluorescence and elisa tests. in sera from 30 participants infected with trypanosoma cruzi, and in 30 non infected the four techniques produced entirely equivalent results, all positive and all negative, respectively. in cases admitted to be inconclusive or in visceral leishmaniasis, frequent false positives were detected. however, tesa blot contributed with the least proportion of them.

Health (Health) , 2014, DOI: 10.4236/health.2014.621343
Abstract: Background: Investigating self-perception of oral health among the elderly may contribute towards changing public health and assistance policies in the area. Methods: The present study assessed the oral health status (tooth decay, need for treatment, periodontal status, use of and need for dental prosthesis, soft tissue alterations and self-perception of oral health) of 102 elderly people from two community groups in Fortaleza, Ceará State, Brazil. Results: Mean age was 69.9 years and 82.4% were female. Mean DMFT was 30.17 with a predominant missing component; 63.7% were edentulous. Regarding prosthesis, 29.4% and 67.6% of elderly patients did not use upper and lower dentures respectively, while 66.7% and 78.4% required some type of upper and lower prosthesis respectively. Among valid sextants, 44.3% presented dental calculus and 34.3% presented loss of attachment from 6 to 8 mm. Soft tissue alterations were found in 58.8%. Despite of precarious clinical conditions and dental treatment needs, good oral health perception was found (49%), as well as satisfaction with the appearance of teeth and gums (60.8%). Conclusion: Subjects displayed unsatisfactory oral health conditions, accumulated over time and resulting from the lack of policies favoring this age group. There is a need for oral rehabilitation that enables the recovery of function and esthetics among the elderly, restoring their self-esteem and improving social interaction.
