<b>BACKGROUND:</b> Evidence-based medicine has had a profound impact on healthcare. In the field of Plastic surgery, powerful examples include; less radical skin cancer excision margins and skin-sparing or even nipple-sparing mastectomies and microsurgical reconstruction. Sustained progression of the field, relies on the development of a high-quality evidence base, with strong use of peer-reviewed research protocols, which are publicly registered and completed studies transparently reported. The extent of compliance with these principles is currently unknown and the author hypothesised that it would be low. The author further hypothesised that registration could be improved by the development of a new global research registry and reporting quality can be improved by the mandatory implementation of reporting guidelines in a journal. <b>METHODS:</b> This thesis incorporated 11 studies. The first two studies used a literature review to determine; the levels of evidence, rates of study registration and protocol publication in the recent Plastic Surgery literature. Thirdly, the design, build and launch of a new global research registry to boost compliance with registration and to determine barriers to it using a survey amongst users. This would be followed by systematic reviews to determine compliance with the STROBE and PRISMA guidelines respectively. An analysis of each guide for authors (GFA) of the surgical journals listed in the Thomson Reuters journal citation report for surgery to determine support for reporting guidelines. The impact of the mandatory implementation of reporting guidelines in a surgical journal would be assessed using a before and after design. Finally, to develop a reporting guideline for surgical case reports (SCARE) and surgical case series (PROCESS) using a DELPHI consensus exercise amongst an expert panel. <b>RESULTS:</b> Protocols were registered in 4% of 595 recent research studies and 0.5% were published. There was a mean compliance of 12/22 for the STROBE guideline (n=94) and 16/27 for the PRISMA guideline (n=79). The Research Registry® was launched in February 2015. Analysis of the first 500 previously unregistered studies, showed they came from 57 countries and included 1.77 million patients. Key barriers to registration were a lack of awareness of the need to register and lack of time (n=149). In addition, 45% registered their study at the time of journal submission. The GFA analysis showed 62% didn’t mention reporting guidelines at all (n=193). Subsequent mandatory implementation in a single surgical journal, increased compliance with STROBE by 12% (n=152), with CONSORT by 40% (n=13) and with PRISMA by 58% (n=28). The SCARE and PROCESS reporting guidelines were developed and published in late 2016. According to Google Scholar, they have accumulated over 200 citations at the time of writing. <b>CONCLUSION:</b> Study registration, protocol use and reporting quality are poor in plastic surgery. Potential solutions to these long-standing problems have been developed and explored within this thesis. These include the development and use of the Research Registry® and the mandatory implementation of reporting guidelines, with both measures front-loaded within a gatekeeper framework for journals. It is now for Plastic Surgeons and the wider surgical community to pick up the gauntlet and drive forward high-quality research, evidence-based surgical practice and better outcomes for their patients and society at large.

O objetivo desta pesquisa foi identificar os efeitos adversos relatados por cirurgiões-dentistas (CD) e correlacioná-los com o uso de equipamentos motores. Trata-se de um estudo seccional, não experimental com análise quantitativa dos dados. O estudo foi realizado com 247 CD de Ribeirão Preto-SP. Na coleta dos dados, foi utilizado um questionário auto-aplicável composto por questões agrupadas em: questões sócio-demográficas, relativas a efeitos adversos (musculoesqueléticos, nervosos e vasculares), prática profissional e questões sobre o uso de equipamentos motores. Os dados foram analisados por meio de medidas de distribuição (freqüência), análise bivariada (Teste qui-quadrado e Exato de Fisher) e análise multivariável (Regressão logística). Os efeitos indesejáveis relatados pelos sujeitos e considerados mais intoleráveis foram: dor (67,65%), limitação de amplitude de movimento (7,84%) e parestesia / formigamento (6,86%). As regiões do corpo mais acometidas foram: pescoço, ombros e membros superiores direitos, perfazendo 76,8% das queixas. Os preditores estatisticamente significativos para os efeitos indesejáveis relatados em mãos foram sexo (RC = 0,513, p = 0,056) e pausa entre os atendimentos (RC = 0,514, p = 0,022). O equipamento mais utilizado foi o motor de alta rotação (94,7%), seguido pelos de baixa rotação com contra-ângulo (82,2%) e baixa rotação com peça reta (62,8%). Concluiu-se que embora os CD apresentassem sintomatologia característica de exposição a equipamentos motores que emitem vibração, estes sintomas não são suficientes para confirmar que os equipamentos motores são prejudiciais a sua saúde e que são fatores de risco para a ocorrência de LER/DORT. Os resultados deste estudo oferecem subsídios importantes para a conscientização do cirurgião-dentista sobre sua prática de trabalho e a necessidade de cuidar de sua saúde e levanta questionamentos que possibilitarão a realização de futuras investigações pela equipe multidisciplinar de Saúde do Trabalhador. / This study aimed to identify adverse effects reported by dental surgeons (DS) and correlate them to the use of motor equipment. We carried out a non experimental cross-sectional research with quantitative data analysis. The study involved 247 DS who work in Ribeirão Preto, Brazil. A self-applied questionnaire was used to assess the professionals. This instrument consisted of four parts, asking sociodemographic questions, questions about reported (muscle-skeletal, nervous and vascular) adverse effects, professional practice and questions related to motor equipment use. Data were analyzed through distribution (frequency) measures, bivariate analysis (chi-square and Fisher?s exact test) and multivariate analysis (logistic regression). Within the described undesirable effects, the ones these professionals considered most intolerable are pain (67.65%), movement range limitation (7.84%) and paresthesia/tingling (6.86%). The most affected body regions were neck, shoulders and right superior limbs, corresponding to 76.8% of complaints. The reported predictors statically significant for the undesirable effects on hands were gender (RC = 0,513, p = 0,056) and pause between appointments (RC = 0,514, p = 0,022). These professionals most frequently used high-speed rotating equipment (94.7%), followed low-speed rotation equipment with contra-angle (82.2%) and low-speed rotation equipment with a straight piece (62.8%). Although the symptoms these professionals present are characteristic of exposure to vibrating motor equipment, these symptoms are not sufficient to confirm that motor equipments cause damage to health and are factors of risk to the occurrence of RSI and WMSD. The results of this study offer important support to the consciousness of the Dental Surgeon about his(er) practice and the need to care of his(er) health and raises questions that can give rise to further research by the multidisciplinary team on the worker?s health.

P.A Supervisão de Saúde de São Mateus forneceu os endereços de todas as Unidades Básicas de Saúde e seus respectivos cirurgiões dentistas para obtenção do total de profissionais da rede pública local. Para obtenção dos endereços dos profissionais da rede privada, buscou-se cadastro em empresas dental da região, alguns dados recebidos do Conselho Regional de Odontologia e cadastro na subprefeitura da região. Um questionário foi aplicado a 133 profissionais. Na análise da cobertura vacinal, observou-se que 78,2 % dos profissionais tomaram as três doses preconizadas ou mais e, dos que tomaram a vacina, observou-se que somente 49,0% realizaram o exame antiHBs para comprovarem se estavam imunizados. Dos profissionais entrevistados, apenas 3 % não tomaram nenhuma dose da vacina e 14,3 % tomaram duas doses. Percebeu-se que boa parte dos cirurgiões dentistas pode estar exposto ao vírus da hepatite B, visto que, 51,2% dos profissionais afirmaram terem sofrido algum acidente com perfuro-cortante. Os profissionais conhecem a doença, pois 97,0 % tomaram pelo menos uma dose, mas efetivamente esse conhecimento não gera a ação de vacinação completa e a realização do antiiHBs.Os cirurgiões dentistas que trabalham na rede pública estão mais protegidos e com melhor cobertura vacinal dos que os trabalham na rede privada. Os resultados desse estudo refletem a necessidade de implementação de campanhas que conscientizem os profissionais sobre a necessidade de vacinação completa contra a hepatite B / Abstract: This study examined the vaccination coverage for hepatitis B and related factors of the dentists who work in public and private areas in the region of the sub city of Sao Mateus (in the capital of the city of Sao Paulo). The local health supervision has provided the addresses of all the Basic Health Units and its respective professionals, to reach the private professional dentists it was necessary to contact the National Board of Dentistry and some other public servers. A questionnaire was applied to 133 professionals. During the analysis of the immunization coverage it was observed that only 78,2% of the professionals were immunized with the tree shots recommended or more and among those who received the shots only 49,0% realized the antiHBs exam which proves if the vaccine was efficient. In general only 3,0% didn't get any shots of the medication and among 14,3% received at least 2 shots. The bottom line is that a significant amount of dentists can be exposed to the Hepatitis B virus, considering that, 51,2% of them confessed to have suffered some kind of accident with sharp instruments. The professionals are all aware of the disease, the proof is that 97% of them took at least one shot of the vaccine but they responsibility is limited once the treatment is not effective if incomplete, not to mention the realization of the antiHBs. The dentists who work for public organizations have a better protection than those who work for private enterprises. The outcome of this study is to aware all the professionals about the need of having a complete protection against the Hepatitis B virus / Mestrado / Mestre em Odontologia em Saúde Coletiva

Dr. Christiaan Neethling Barnard (Barnard) was a world renowned surgeon who made medical history when he performed the world’s first human heart transplant. Barnard was celebrated by some for his courage and contribution in advancing the field of cardiothoracic surgery, while others believed that the technique of human heart transplantation was not his own. Barnard became known for his controversial lifestyle, and acquired a reputation as a playboy. He died in 2001 at the age of 78, following an asthma attack. The aim of the current study was to explore and describe the personality development of Barnard, by applying Alfred Adler’s theory of Individual Psychology to the context of his lived life. The study used a single case study research design, and purposive sampling was used to select the subject. This selection was made on the basis of the researcher’s interest in Barnard’s life history and his immense contribution to medical science. Data sampled was qualitative, and was collected from primary and secondary data sources. Collected data was analysed in accordance with Alexander’s model of data analysis. The findings of the study indicated that Barnard’s life was in many respects aligned with Adler’s theory and that his striving for significance was largely influenced by his social environment as well as the cultural context in which he lived.

This master thesis aims to show how a qualitative approach to early modern medical practitioners’ perspectives can provide a basis for a better understanding of the disease of dysentery. The focus is on: 1) How the disease of dysentery was described and how the challenge of dysentery was perceived. 2) What individual measure and commitments were taken for the patients and why. 3) How the cause of the disease was understood and explained. 4) How perspectives differed between physicians and surgeons.Of particular interest when it comes to the disease of dysentery is how the disease and its cause were perceived.Eleven texts written by mainly British medical practitioners from primary sources such as reports, logbooks and letters on dysentery written during the years 1740 - 1800 have been used for close readings and a qualitative analysis was performed on the collected data.The analysis showed (i) that medical practitioners expressed considerable interest in dysentery and in trying to understand it as a great suffering for individuals, for society and for humanity as a whole. (ii) Medical practitioners took treatment measures based on how they understood the cause of the disease outbreak. Either the dysentery was referred to internal causes, as sickness in organs, especially the organs that produced bodily fluids, or it was referred to external causes, as a sickness caused by heat, cold, weather, winds, air, climate, seasons, lunar position, etc. (iii) The cause of the disease was understood and explained both as an infection and as a pre-disposition for imbalances in body fluids. (iv) Both physicians and surgeons understood that the disease of dysentery was a global phenomenon and that the disease often was connected to the climate and weather. This standpoint was based on the fact that dysentery distinguished itself as an autumnal disease. Its eruption usually began with a few scattered cases in July, then increased in August and culminated in September. Theories about the disease, its causes and treatment did not differ significantly between physicians and surgeons. However, the views of different physicians did differ.The thematic map of understanding related to disease of dysentery, shows that medical practitioners’ knowledge, theories and ideas behind the medical practice of dysentery, have an ambiguity in the view of both the dysentery and the treatment of it. This was probably due to interpretation based both on observable causes of diseases, and on a more theoretical abstract meaning, where diseases to a greater extent was understood on the basis of symptoms and signs.It is suggested that regardless of the knowledge base of the individual medical practitioner, no one represented an independent knowledge base for their treatment of dysentery; rather they participated actively with each other in a mutually constitutive way in order to shape their understanding of the dysentery. This theses’ qualitative approach, allows dysentery patients and their medical practitioners via the texts of the medical practitioners, to offer very personal accounts of a highly contagious disease.

Most recent research on gender affirmation/reassignment surgery focuses on discrimination and health disparities faced by the transgender community, and on perspectives and identity constructions of patients transitioning from one gender presentation to another. However, few studies address perspectives and experiences of the surgeons performing these operations. This exploratory study examines narratives of some of these surgeons in order to understand how they entered this particular practice, and how they perceive and classify these procedures. This study also aims to show the affect these procedures have on these surgeons and their discipline, and how these surgeons navigate the complex relationships between patients, healthcare providers, and surgeons, in the context of social values and popular media perspectives in the United States.

Thesis (MA (Industrial Psychology))--University of Stellenbosch, 2007. / The primary objective of the study was to describe Professor Christiaan Barnard’s career development according to the theoretical model formulated by Greenhaus, Callanan and Godshalk (2000). The research design implemented in the study is a exploratory-descriptive psychobiographical case-study that followed an idiographic-morphogenic research strategy and used qualitative data to present a coherent narrative of Barnard’s career development. During the study biographical and autobiographical data pertaining to Barnard’s career development were collected and analysed. Barnard was selected as psychobiographical subject through a purposive sampling strategy. Barnard was regarded as an appropriate subject for the study because of his extraordinary and pioneering contributions in the context of organ transplants. The study used qualitative data and included both primary (autobiographical material) and secondary data (biographical material). The data collection and data analyses were based on an approach suggested by Yin (2003). This approach uses a theoretical model to determine the relevance of data as well as the nature of data that would facilitate the achievement of the research objective. It is implemented by posing specific questions to the data. The data analysis procedure was based on the approach suggested by Huberman and Miles (1994). Their approach comprises three phases, namely data-reduction, data-display, and conclusion drawing or verification. The researcher ensured ethical standards throughout the study by obtaining Barnard’s consent to conduct the study. The researcher treated personal information with respect, empathy, thoughtfulness and prudence. Only data available in the public domain (published biographical and autobiographical material) were considered during the data analysis phase. Lastly, the researcher attempted to interpret data in a responsible and transparent manner. The analysis of Barnard’s career development according to the theoretical model of Greenhaus et al. (2000) demonstrated the value of the model to accurately describe and interpret the career development of extraordinary individuals.

INTRODUÇÃO: A educação neurocirúrgica requer muitos anos de treinamento prático e supervisionado. O desenvolvimento de plataformas de simulação cirúrgica é, portanto, essencial para reduzir o risco de erros intraoperatórios potencialmente graves decorrentes da inexperiência. Este estudo considera o treinamento cirúrgico para tratamento de hidrocefalia e cranioestenose. OBJETIVOS: Propor uma nova ferramenta para a educação neurocirúrgica, associando à simulação virtual e realística (realidade mista), para a correção da cranioestenose (tipo escafocefalia) e treinamento neuroendoscópico. MÉTODOS: Os simuladores físicos foram confeccionados com um silicone emborrachado termorretrátil e termossensível. Para validar os modelos de neuroendoscopia e cranioestenose, cirurgiões experientes participaram deste estudo usando vídeos de reconstrução tridimensional desenvolvidos pelo programa 3DS Max. Questionários sobre o papel dos simuladores virtuais e realísticos foram aplicados aos neurocirurgiões em relação à aplicabilidade da simulação de realidade mista para ambos os treinamentos cirúrgicos. O modelo virtual craniano foi criado com a obtenção de imagens no formato DICOM. Esta informação foi então processada usando um algoritmo de computação para gerar um biomodelo tridimensional em resina. O modelo e suas possibilidades de treinamento também foram avaliados qualitativamente por uma equipe de neurocirurgiões. Posteriormente, os especialistas avaliaram a aplicação da ferramenta para residentes em neurocirurgia. RESULTADOS: Os cirurgiões experientes consideraram a simulação mista como uma ferramenta potencial para o treinamento de novos residentes em neurocirurgia. Mais de 94% deles julgaram os simuladores adequados considerando aspectos como peso, posicionamento cirúrgico, dissecção por planos e reconstrução craniana. Em relação à experiência do modelo, cinco neurocirurgiões especialistas e 12 residentes de neurocirurgia participaram da avaliação. Todos consideraram a ferramenta positiva para o treinamento proposto. Os especialistas comentaram sobre quão interessante o modelo pode ser, instigando a compreensão das razões de cada etapa cirúrgica e de como atuar nelas. Os residentes apresentaram melhor clareza na visualização tridimensional, auxiliando indiretamente na compreensão da técnica cirúrgica. Além disso, eles notaram uma notável redução de erros em cada tentativa de montar o modelo. Os residentes consideraram ser um método de ensino cuja avaliação é objetiva e clara. CONCLUSÃO: Uma mistura de simulação física e virtual fornece previamente as habilidades psicomotoras e cognitivas necessárias, que são adquiridas apenas durante a aprendizagem prática cirúrgica. Finalmente, o quebra-cabeça pode ser uma importante ferramenta complementar, permitindo graus variados de imersão e realismo. Forneceu uma noção de realidade física, oferecendo informações dinâmicas simbólicas e geométricas, com rica visualização tridimensional. O uso de simuladores pode potencialmente melhorar e abreviar a curva de aprendizado dos cirurgiões / that requires many years of supervised hands-on training. The development of surgical simulation platforms is therefore essential to reducing the risk of potentially serious intraoperative errors arising from inexperience. This study considers the surgical training for hydrocephalus and craniosysnostosis treatment. OBJECTIVES:To propose a new tool for neurosurgical education, associating virtual and realistic simulation (mixed reality), for craniosynostosis correction (scaphocephaly type) and neuroendoscopic training. In addition, we sought to develop a \"puzzle\" to simulate the scaphocephaly surgical correction using Renier\"s \"H\" technique and to evaluate the learning impact for neurosurgery residents. METHODS: Physical simulators were made with a synthetic thermo-retractile and thermosensible silicone rubber. In order to validate the neuroendoscopy and craniosynostosis models, experienced surgeons participated in this study using tridimensional reconstruction videos developed by 3DS Max program. Questionnaires regarding the role of virtual and realistic simulators were applied to experienced neurosurgeons regarding the applicability of the mixed reality simulation for both surgery training. The puzzle cranial model was created by obtaining images through a multi slice CT scan DICOM format. This information was then processed using a computing algorithm to generate a three-dimensional biomodel in resine. The puzzle and its training possibilities were also evaluated qualitatively by a team of expert neurosurgeons. Subsequently the experts evaluated the application of the tool for residents in neurosurgery and the residents also evaluated the experience. RESULTS: The experienced surgeons considered the mixed reality simulation as a potential tool for training new residents in neurosurgery. More than 94% found the simulators appropriate considering aspects such as weight, surgical positioning, dissection by planes, and cranial reconstruction. Regarding the puzzle experience, five experts neurosurgeons and 12 neurosurgery residents participated in the evaluation. All considered the tool positive for the proposed training. The experts have commented on how interesting the model may be by instigating the understanding of the reasons for each surgical step and how to act in them. Residents presented better clarity in the three-dimensional visualization of the step by step, indirectly aiding in the understanding of the surgical technique. In addition, they noted a notable reduction of errors with each attempt to assemble the puzzle. Residents considered it to be a teaching method that makes assessment objective and clear. CONCLUSION: A mixture of physical and virtual simulation provide the required psychomotor and cognitive skills previously acquired only during practical surgical apprenticeship. Finally, puzzle in cranial shape may be an important complementary tool, allowing varying degrees of immersion and realism. It provided a notion of physical reality, offering symbolic, geometric and dynamic information, with rich tridimensional visualization. The simulators use may safely improve and abbreviate the surgeons learning curve
