The aim of this study was to review original scientific articles describing the relationship between atmospheric pollution and damage to human health. We also aimed to determine which of these studies mentioned public policy issues.Original articles relating to atmospheric pollution and human health published between 1995 and 2009 were retrieved from the PubMed database and analyzed. This study included only articles dealing with atmospheric pollutants resulting primarily from vehicle emissions. Three researchers were involved in the final selection of the studies, and the chosen articles were approved by at least two of the three researchers.Of the 84 non-Brazilian studies analyzed, 80 showed an association between atmospheric pollution and adverse effects on human health. Moreover, 66 showed evidence of adverse effects on human health, even at levels below the permitted emission standards. Three studies mentioned public policies aimed at changing emission standards. Similarly, the 29 selected Brazilian studies reported adverse associations with human health, and 27 showed evidence of adverse effects even at levels below the legally permitted emission standards. Of these studies, 16 mentioned public policies aimed at changing emission standards.Based on the Brazilian and non-Brazilian scientific studies that have been conducted, it can be concluded that, even under conditions that are compliant with Brazilian air quality standards, the concentration of atmospheric pollutants in Brazil can negatively affect human health. However, as little discussion of this topic has been generated, this finding demonstrates the need to incorporate epidemiological evidence into decisions regarding legal regulations and to discuss the public policy implications in epidemiological studies.
INTRODUCTION: Currently, there is no correlation between the fields of healthcare and law in Brazil regarding the adoption of public policies aimed at preventing/avoiding, remedying or minimizing the adverse effects of atmospheric pollution on human health. OBJECTIVE: The present study had the objective of demonstrating the increasingly eminent need for interaction between epidemiology and law, thereby revealing that these fields are not autonomous sciences but integrated instruments for use in seeking efficient public policies relating to atmospheric pollution caused by automotive vehicles. METHODS: We built up a systematic review of epidemiological studies relating to the effects of atmospheric pollution on human health, using the PubMed database and well-defined descriptors. The search results then underwent selection by three independent researchers with experience of this topic. A review of the national environmental legislation relating to atmospheric pollution was made, using official databases, including the CONAMA (National Environment Council) standards, and international documents relating to atmospheric emission standards were investigated. We conducted structured interviews with public policymakers in the environmental field, with a view to analyzing the opinions of representatives of this distinct segment of society regarding the matter in question. RESULT: Out of 2,530 studies initially selected, only 32 Brazilian and 112 foreign studies were considered to fit within the inclusion criteria established. Among the Brazilian studies, 27 showed that there were adverse effects on human health even at concentrations lower than what is legally permitted, and 18 discussed public policies in some manner. Among the foreign studies, 78 showed that there were adverse effects on human health even at concentrations lower than what is legally permitted, and 13 discussed public policies. The interviewees unanimously stated that there was a need to update the current emission standards and comply with the emissions timetable, and that there was inadequate understanding between the field of healthcare and the adoption of public policy measures. They showed that they were aware of the scientific research that had been conducted and were concerned about the data presented. CONCLUSION: We thus demonstrated that: there is a need for law and epidemiology to combine in order to draw up public guidelines; a need for the population's awareness to be raised, and for emission standards to be changed and the effective participation from public bodies within the policymaking and healthcare sectors. Identification, recognition and acceptance of the complexity and the research data are the cornerstones of the interface between the domains of science, society and politics.

Purpose Recent papers suggest that patients with multiple sclerosis (MS) are prone to alcohol misuse. This may be due to the combination of a lifelong and disabling disease with a psychiatric profile typical of MS. The objective of the present study was to assess these findings in a culturally different population of patients with MS.Method The present case-control transversal study assessed 168 patients with MS and 168 control subjects from Brazil.Results There were no evidence that patients with MS drank more alcohol or, smoked more than did controls. In fact, control subjects had a significantly higher alcohol consumption. The only trait associated to higher alcohol consumption was anxiety, both for patients and controls.Conclusion Unlike previous reports in the literature, patients with MS in our study did not drink or smoked more than a control population.
Summary Cysticercosis is a parasitic disease caused by a worm of the Cestoda class. The most prevalent form affects the nervous system. This case report is from a 78-year-old female patient evaluated at Clínica Mult Imagem, in the city of Santos, Brazil, who presented a form of the disease that differed from the classic neurocysticercosis, in this case muscular cysticercosis. This and other forms of manifestation justify further studies to ensure adequate recognition, diagnosis and treatment of this parasitic disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
