Abstract
Internet search patterns associated with "windows" of collective interest have been increasingly investigated in the field of public health. This article sets out to identify search patterns relating to the quest for information on skin protection after the perception of excessive exposure to UV radiation - the so-called "summer effect" as it is commonly referred to in Brazil. To calculate the number of hits on the Brazilian National Cancer Institute website - a renowned source of information resources on prevention - log analyzer software was used to measure the volume of hits on specific content pages. The pages on skin protection and self-examination (pages of interest) were monitored over a 48-month period. It was seen that, although the monthly average of hits on pages of interest revealed statistically significant annual growth, the results for the analysis of variance showed no significant differences between the number of hits in the summer compared with other months (p = 0.7491). In short, the perception of intense exposure to the summer sun did not encourage further interest to search for information on prevention.

Abstract
The popularization of ICTs and the availability of information have not influenced the habits of prevention - cancers are lately diagnosed, as before in the scarcity of information era. This paper analyzes patterns of accesses to the National Cancer Institute website (already described in previous articles) as well as contradictions between the purposes and results of cancer prevention campaigns. We identified a reactive pattern of queries which was indifferent to information on prevention, but interested in treatment technologies and news about celebrity's diseases. These findings contrast with the paradigm of the best data for decision making, based in the heteronomy of "banking education", its means and efficacy. We discussthe symbolic power of campaigns under the theoretical framework of emotional heuristic models - analytical tools rarely employed in studies of risks, but here considered essential elements to the comprehention of public perception of health. Ambiguities are portrayed and as well as its pendulum between certainties and uncertainties in the midst on which they are formed. It is discussed the risk tripartition - as perception, analysis and policy, the latest posed as a public clash between the first concerning the major risks aligned to their historical circumstances.

Abstract
The linguistic-communicative paradigm offers some interesting perspectives in a context where the perception of patient needs is considered a critical step in high-quality care. This study describes healthcare organizations as linguistic communities based on the conceptual framework of Habermas' communicative action theory. Four communicative models are present in healthcare settings: objectifying-instrumental (hegemonic model), where elements of interaction are objectified for clinical purposes; dialogic model with strategic perspectives, in which conversations are used unilaterally as tools to access subjective states; non-dialogic-transmissional model, in which linguistic exchanges are replaced with artifacts to transmit information; and full communicative model (present in palliative care based in homecare and informal caregivers, emphasizing health team/family interactions). Based on these premises, we considered palliative care an emblematic communicative model based on multidisciplinary teams devoted to transdisciplinary collaboration. In these settings, linguistic interaction with patients and their families could provide a solid basis for organization of healthcare networks.

Abstract
Trata-se de um estudo de recepção de mensagens por trabalhadores da construção civil. Utilizamos como mediação os materiais educativos (cartazes, folders e cartilhas) produzidos pelo Ministério da Saúde e Ministério do Trabalho e Emprego. Realizamos dois grupos focais, em dois canteiros de obra no Município do Rio de Janeiro, Brasil, para a análise de quatro materiais educativos; utilizamos análise temática. Apresentamos o ponto de vista dos trabalhadores sobre os temas discutidos nos impressos, classificados em dois núcleos de sentidos: saúde e controle social. Discutimos que os trabalhadores apresentam uma visão ampliada de saúde à medida que inclui os determinantes sociais ao processo saúde-doença. Identificamos a pouca participação dos trabalhadores nas ações de fiscalização dos processos de trabalho, e o desconhecimento das ações de saúde do trabalhador desenvolvidas pelo Ministério da Saúde. Concluímos que a análise de materiais educativos por seus destinatários, representa um lugar privilegiado de negociação de sentidos e de apreensão dos modos de viver de grupos específicos. Sugerimos a realização de atividades educativas que utilizem os impressos como mediação para motivar a problematização do processo saúde-doença.

Abstract
Este trabalho se ocupa dos típicos sistemas semânticos extraídos dos recursos comunicativos de equipes hospitalares, que tentam validar informações como um "objeto" a ser transferido aos pacientes. Descrevemos modelos de comunicação textual em 58 impressos de orientações aos pacientes de cinco unidades hospitalares, coletados de 1996 a 2002. Identificamos três categorias fundamentadas na teoria dos atos de fala (Austin, Searle e Habermas): (1) Proferimentos cognitivo-instrumentais - descrições por meio de termos técnicos validados por argumentação auto-referente, incompleta ou inacessível; função educativa implícita. (2) Proferimentos técnico-diretivos - auto-referentes (contexto dos setores de origem); deslocamento freqüente de atos cotidianos para o terreno técnico com função disciplinadora; impessoalidade. (3) Modulações expressivas: necessidade de conexões intersubjetivas para fortalecer laços de confiança; tendência à infantilização. Concluímos que as categorias estudadas expõem: base em origens fragmentárias; pressupostos de univocidade de mensagens e consumo invariante da informação (motivações e interesses idealizados, alheios às perspectivas individuais); pressuposto de interesses universais como geradores de conhecimento.

Abstract
Review was made of publications that describe experience with printed material distributed to the lay public in hospital institutions. From the 146 leaflets examined, those aimed at professionals or disabled people, thus leaving 75 papers that illustrate the present pattern for the rationality behind the production, use and evaluation of this type of resource. In a general manner, such leaflets invest in the power of "ideal printed information" to align behavior with the hospital's biomedical agenda. The underlying rationality that permeates them perceives the "perfect information package" as one that efficiently describes its technical content for the purpose of unidirectional persuasion, is up-to-date in relation to readability scales and embellished by graphic design, and emphasizes the priorities defined by the professionals. Such "communication prostheses" should be capable of electronic validation by means of software suitable for proportioning the "doses" to the subject matter. Information as a drug, cognitivism, the lack of research on message reception and the need for communicative action for the deconstruction of systems of closed thinking within the hospital environment have been discussed.

Abstract
A national study was conducted of community pharmacists to examine influences on their communication with consumers about antibiotics and antibiotic resistance. The objective was twofold: to explore the nature of barriers that might be changed to allow pharmacists greater participation in educational campaigns, and to discover which variables would best predict communication using a modification of the Theory of Reasoned Action model. Whereas most pharmacists agreed that their role in educating patients is important, they also noted several barriers prevent them from engaging in campaigns, such as time constraints, lack of educational materials, and fear of harming relations with physicians. Pharmacists' discussion about antibiotics in general was predicted primarily by attitudes about their role and efficacy, by their autonomy, and by enabling measures-such as pamphlets-that would better aid them in participating in a judicious antibiotic use campaign. Discussion about resistance was predicted by attitudes and enabling measures.

Abstract
Based on interviews in a hospital in Rio de Janeiro, the authors analyze strategies, interests, assumptions, and concerns among producers of patient information leaflets on infectious diseases. Most such publications followed a linear communications model, according to which health messages produce a sole and single effect on their audience. Visual communications are seen as a field of knowledge over which physicians have no "command", but which raises great expectations on their part, principally in light of the limits of written language for an illiterate patient population. The most frequent concerns relate to the "adequacy of the language" (a denotative, non-semantic function of language) and on the increase in "dissemination". Leaflets are generally linked to the professional experience of providing health care, but the lack of pertinent research prior to the production of such publications leads to simplifications and generalizations concerning the patients' most common doubts and questions, reinforcing the stereotyping of the clientele based on their lacks and needs. In two exceptional leaflets, interaction with the clientele appears and expands the relationship between the health care professionals and the values and decisions made in distinct sociocultural contexts.

Abstract
Gammaherpes viruses are often detected in lymphomas arising in immunocompromised patients. We have found that Azidothymidine (AZT) alone induces apoptosis in Epstein Barr Virus (EBV) positive Burkitt's lymphoma (BL) cells but requires interferon alpha (IFN-alpha) to induce apoptosis in Human Herpes Virus Type 8 (HHV-8) positive Primary Effusion Lymphomas (PEL). Our analysis of a series of AIDS lymphomas revealed that IFN-alpha selectively induced very high levels of the Death Receptor (DR) tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) in HHV-8 positive PEL lines and primary tumor cells whereas little or no induction was observed in primary EBV+ AIDS lymphomas and EBV-Burkitt's lines. AZT and IFN-alpha mediated apoptosis in PEL was blocked by stable overexpression of dominant negative Fas Associated Death Domain (FADD), decoy receptor 2 (DcR2), soluble TRAIL receptor fusion proteins (DR-4 and DR-5) and thymidine. Trimeric TRAIL (in place of IFN-alpha) similarly synergized with AZT to induce apoptosis in HHV-8 positive PEL cells. This is the first demonstration that IFN-alpha induces functional TRAIL in a malignancy that can be exploited to effect a suicide program. This novel antiviral approach to Primary Effusion lymphomas is targeted and may represent a highly effective and relatively non-toxic therapy.
