- Wishing to feel better... perceptions of health and illness in persons with rheumatic diseasesPublication . Sá, Maria do Céu; Oliveira, AbílioAbout a third of the Portuguese population suffers from some form of rheumatic disease. Although the pathology in several persons is mild, these illnesses are chronic and incurable, have a progressive evolution, and the symptoms tend to become increasingly severe. Rheumatic illnesses frequently lead to major consequences for the person's life disturbing their social relationships, work and leisure. The present work is part of a larger project, and aim to understand how health and illness are represented among adults with rheumatic disease. The data was collected by free associations of words and processed through factorial correspondence analysis. Participants were questioned on what they think and feel about their health and illness. Their perceptions were analysed considering their age, sex and years of illness. The participants point out the illness as their major source of suffering and sadness, revealing they frequently feel discouraged, thinking they are different from other people. Women, more than men, express negative emotions and serious difficulties to maintain a healthy and independent lifestyle - they emphasize their functional limitations that seriously affect daily activities, in particular their mobility and housekeeping tasks. In general, men almost accept their health condition - it is as if they feel strong enough to face their illness and to find ways to improve their wellbeing. What the patients think and feel about their health and illness may convey important information for health professionals, working with patients with rheumatoid disease, in order to help them to improve strategies to deal with this population.

- Liability for environmental damage in Portugal - a short overviewPublication . Mendes, Jorge BarrosThe environmental law enshrined as a fundamental principle in article 66 of the Portuguese Constitution. The Environmental Liability Directive establishes a framework of environmental liability, based on the "polluter-pays" principle, to prevent and remedy environmental damage. The Decree-Law 147/2008, of 29th July came transpose into Portuguese law Directive 2004/35/EC of the European Parliament and of the Council of 21st April 2004. The Law 67/2007, of 31st December, establishing in Portugal the regime for tort liability arising from losses caused by third parties, due to the acts of public management in relation to all the functions of the State, i.e. i) administrative, ii) legislative, and iii) jurisdictional.
- Quality assurance and quality control in mammography: a review of available guidance worldwidePublication . Reis, Cláudia; Pascoal, Ana; Sakellaris, Taxiarchis; Koutalonis, ManthosObjectives: Review available guidance for quality assurance (QA) in mammography and discuss its contribution to harmonise practices worldwide. Methods: Literature search was performed on different sources to identify guidance documents for QA in mammography available worldwide in international bodies, healthcare providers, professional/scientific associations. The guidance documents identified were reviewed and a selection was compared for type of guidance (clinical/technical), technology and proposed QA methodologies focusing on dose and image quality (IQ) performance assessment. Results: Fourteen protocols (targeted at conventional and digital mammography) were reviewed. All included recommendations for testing acquisition, processing and display systems associated with mammographic equipment. All guidance reviewed highlighted the importance of dose assessment and testing the Automatic Exposure Control (AEC) system. Recommended tests for assessment of IQ showed variations in the proposed methodologies. Recommended testing focused on assessment of low-contrast detection, spatial resolution and noise. QC of image display is recommended following the American Association of Physicists in Medicine guidelines. Conclusions: The existing QA guidance for mammography is derived from key documents (American College of Radiology and European Union guidelines) and proposes similar tests despite the variations in detail and methodologies. Studies reported on QA data should provide detail on experimental technique to allow robust data comparison. Countries aiming to implement a mammography/QA program may select/prioritise the tests depending on available technology and resources. Main messages •An effective QA program should be practical to implement in a clinical setting. •QA should address the various stages of the imaging chain: acquisition, processing and display. •AEC system QC testing is simple to implement and provides information on equipment performance.

- I-49. Influência do Ozono no processo de colonização bacteriana em TitânioPublication . Pintado, Carlos; Vaz, Paula; Pintado, Manuela; Costa, Eduardo; Rocha, Luis A.; Felino, AntonioObjetivos: com uso de implantes dentários, surgem casos de ocorrência de peri-implantite, que se instala e permanece causando perda óssea peri-implantar podendo culminar no fracasso do implante dentário. Recentemente foram colocados no mercado equipamentos para aplicação de Ozono em medicina dentária, cuja aplicabilidade se baseia na potencial ação bacteriostático do Ozono mas da qual a evidência científica ainda é escassa. Deste modo, este estudo pretendeu avaliar a eficácia antimicrobiana do Ozono em culturas de Staphylococcus aureus sobre discos de titânio. Materiais e métodos: o efeito do ozono na formação de biofilme bacteriano pelo Staphylococcus aureus (Sa) foi testado através do uso de microplacas de 24 poços e de 8 discos de titânio com 1 cm2 de área e com uma superfície tratada quimicamente por aplicação de um ataque ácido (ácido fluorídrico ácido nítrico água na proporção 1:1:1). Cada disco foi revestido com um volume de inóculo correspondente a 1x108 ufc/ml e seco durante 30 min em condições assépticas. Cada disco inoculado foi tratado com jato de ozono durante 40 segundos, usando o HealOzone® (KaVo Dental GmbH, Biberach, Germany). Após esta aplicação do ozono os discos foram submersos em poços com 2 ml de 1% Tryptic Soy Broth (Difco®) e glucose a 1% (Sigma-Aldrich®). Simultaneamente, foi realizado um controlo positivo-disco e um controlo negativo. Após 48 h os discos foram recuperados e o número de unidades formadoras de colónias (UFC) foi determinado através do método Miles and Misra em Plate Count Agar (Merck®). As placas foram incubadas a 37 °C durante 24 h. Os resultados foram analisados aplicando a seguinte formula: %inibição = 100–(LOG UFCAMOSTRA COM OZONO/LOG UFCAMOSTRA SEM OZONO)x100. Resultados: verificou-se que houve uma inibição de crescimento do Sa de 31,4% após a aplicação do ozono. O tratamento da superfície do disco de titânio conduziu a uma redução de cerca de 2.5 ciclos logarítmicos. A analise estatística efetuada pelo método de Mann Whitney revelou a existência de uma diferença estatisticamente significativa entre os 2 grupos (com e sem aplicação de ozono) com o p = 0,0286. Conclusões: a aplicação do ozono em discos de titânio numa superfície revestida com elevado número de Sa (1x108 ufc/ml) conduziu a um efeito bacteriostático, demonstrando assim a potencial relevância deste equipamento na peri-implantite. São necessários mais estudos in vivo, com diferentes superfícies de implantes, para se testar a eficácia do Ozono no tratamento da patologia peri-implantar.
