Umbilical endometriosis without previous pelvic surgery

OBJETIVO: apresentar série de casos de endometriose na cicatriz umbilical, em pacientes no menacme, sem cirurgias pélvicas prévias. MÉTODOS: foram incluídas no estudo quatro pacientes com idade entre 33 e 43 anos, com queixa de sangramento umbilical associado ou não a dor pélvica, com evolução de dois meses a quatro anos. A ultra-sonografia da parede abdominal foi utilizada para o diagnóstico, procedendo-se à exérese cirúrgica das lesões sugestivas de endometriose umbilical e confirmação anatomopatológica. RESULTADOS: as avaliações ultra-sonográficas das quatro pacientes evidenciaram imagens umbilicais hipoecogênicas compatíveis com a hipótese diagnóstica de endometriose e, assim, todas elas foram encaminhadas para exérese cirúrgica da lesão. A dosagem do marcador sérico CA-125 foi realizada em três das quatro pacientes, com níveis dentro da normalidade, variando de 6,8 a 10,1 U/mL. A concomitância de endometriose pélvica apenas foi confirmada em uma paciente. Durante o seguimento de um ano, as pacientes não apresentaram recidiva dos sintomas nem das lesões. CONCLUSÕES: a endometriose umbilical é uma entidade nosológica rara, mas que deve ser sempre lembrada quando da presença de nodulações ou sangramento umbilicais, ainda que não exista relato de cirurgia pélvica prévia com manipulação endometrial. Seu tratamento cirúrgico é, em geral, suficiente para a remissão total da lesão e dos sintomas.PURPOSE: to present a series of cases of umbilical endometriosis in patients in reproductive age, with no previous pelvic surgery. METHODS: four patients aged between 33 and 43 years were included in the study. They all presented umbilical bleeding associated or not with pelvic pain, and medical history varied from two months to four years. Abdominal wall ultrasound was performed for diagnosis support before surgical excision of the umbilical lesions, and histological examination was also performed. RESULTS: the ultrasonographic evaluation of the four patients showed hypoechogenic umbilical lesion suggestive of endometriosis. All patients were submitted to surgical excision and histological examination of the lesions. CA-125 serum levels were measured in three of the patients, but they were within normal ranges (from 6.8 to 10.1 U/mL). In addition to umbilical surgery, laparoscopy was performed in all patients, but only one presented concomitant pelvic endometriosis. In a one-year follow-up, patients maintained asymptomatic and there was no recurrence of the lesions. CONCLUSIONS: umbilical endometriosis is a rare entity, but it may be remembered as a possibility in cases of umbilical nodulations or bleeding, even if there is no previous history of pelvic surgery with endometrial manipulation. Its treatment is always surgical and, in general, it is enough to promote complete elimination of the lesion and of the symptoms

Taking the pulse of Earth's tropical forests using networks of highly distributed plots

Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of funding agencies. Here we show how a global community is responding to the challenges of tropical ecosystem research with diverse teams measuring forests tree-by-tree in thousands of long-term plots. We review the major scientific discoveries of this work and show how this process is changing tropical forest science. Our core approach involves linking long-term grassroots initiatives with standardized protocols and data management to generate robust scaled-up results. By connecting tropical researchers and elevating their status, our Social Research Network model recognises the key role of the data originator in scientific discovery. Conceived in 1999 with RAINFOR (South America), our permanent plot networks have been adapted to Africa (AfriTRON) and Southeast Asia (T-FORCES) and widely emulated worldwide. Now these multiple initiatives are integrated via ForestPlots.net cyber-infrastructure, linking colleagues from 54 countries across 24 plot networks. Collectively these are transforming understanding of tropical forests and their biospheric role. Together we have discovered how, where and why forest carbon and biodiversity are responding to climate change, and how they feedback on it. This long-term pan-tropical collaboration has revealed a large long-term carbon sink and its trends, as well as making clear which drivers are most important, which forest processes are affected, where they are changing, what the lags are, and the likely future responses of tropical forests as the climate continues to change. By leveraging a remarkably old technology, plot networks are sparking a very modern revolution in tropical forest science. In the future, humanity can benefit greatly by nurturing the grassroots communities now collectively capable of generating unique, long-term understanding of Earth's most precious forests.Additional co-authors: Susan Laurance, William Laurance, Francoise Yoko Ishida, Andrew Marshall, Catherine Waite, Hannsjoerg Woell, Jean-Francois Bastin, Marijn Bauters, Hans Beeckman, Pfascal Boeckx, Jan Bogaert, Charles De Canniere, Thales de Haulleville, Jean-Louis Doucet, Olivier Hardy, Wannes Hubau, Elizabeth Kearsley, Hans Verbeeck, Jason Vleminckx, Steven W.

Evaluation of apoptosis in adjacent endometrium at polyps and carcinomas of the endometrium in postmenopause

A apoptose é um mecanismo fundamental para a homeostase do tecido endometrial. No entanto, seu papel no desenvolvimento das lesões benignas e malignas do endométrio não está totalmente esclarecido. O objetivo deste estudo foi avaliar a ocorrência de apoptose nos carcinomas e nos pólipos endometriais e em seus endométrios adjacentes. Foram incluídas 40 pacientes, 15 com adenocarcinoma de endométrio do tipo endometrióide e 25 com pólipo endometrial. A apoptose foi identificada na lesão neoplásica e em seu endométrio adjacente através da coloração de hematoxilina e eosina (HE) e do método TUNEL (TdT-mediated dUTP-biotin Nick End-Labelling) e os resultados foram expressos como índice de apoptose [(número de células em apoptose/ número total de células) X 100]. A mediana do índice de apoptose (IA) pelo método HE foi 1,2% no carcinoma, 1,06% no endométrio adjacente ao carcinoma, 0,54% no pólipo e 0,1% no endométrio adjacente ao pólipo. Pelo método TUNEL, o IA foi 0,73% no carcinoma, 1,05% no endométrio adjacente ao carcinoma, 0,35% no pólipo e 0,06% no endométrio adjacente ao pólipo. Os métodos HE e TUNEL apresentaram um coeficiente de correlação de Spearman (r) > 0,6 em todos os grupos. Concluiu-se que o carcinoma de endométrio apresenta índice de apoptose maior do que o pólipo endometrial, e que o endométrio adjacente ao carcinoma apresenta índice de apoptose maior do que o endométrio adjacente ao pólipo endometrial.Apoptosis is a fundamental mechanism for homeostasis of endometrial tissue. However, its role in the development of benign and malign endometrial lesions is not completely understood. The aim of the study was to evaluate the occurrence of apoptosis in endometrial carcinomas and polyps as well as in their adjacent endometrium. Forty cases were assessed: 15 endometrial adenocarcinomas and 25 endometrial polyps. We identified the apoptosis in neoplastic and adjacent tissue by the Hematoxylin and Eosin (HE) staining and TUNEL (TdT-mediated dUTPbiotin Nick End-Labelling) assay and quantified it by the apoptotic index [(apoptotic cells/ cells) X 100]. Median of apoptotic index (AI) by the HE method was 1,2% in carcinoma, 1,06% in adjacent endometrium at carcinoma, 0,54% in polyp and 0,1% in adjacent endometrium at polyp. By the TUNEL method, the AI was 0,73% in carcinoma, 1,05% in adjacent endometrium at carcinoma, 0,35% in polyp and 0,06% in adjacent endometrium at polyp. The HE and TUNEL methods showed Spearman correlation coefficient (r) >0,6 in every groups. We conclude that carcinoma of the endometrium showed apoptotic index greater than in endometrial polyp, and that adjacent endometrium of carcinoma showed apoptotic index greater than in adjacent endometrium at endometrial polyp

Applications of minimally invasive surgery in chronic pelvic pain: bioethical issues

A laparoscopia é considerada um importante recurso para o diagnóstico da dor pélvica crônica e, por ser um recurso tecnológico relativamente novo e economicamente dispendioso, traz consigo alguns questionamentos bioéticos. Dentre eles, o estudo dos fatores que influenciam a autonomia é questão importante para a compreensão do fenômeno e a busca de soluções. O objetivo deste estudo foi analisar quantitativamente os pressupostos da autonomia, quais sejam, a informação, a competência e a liberdade, em mulheres com indicação de cirurgia minimamente invasiva para o diagnóstico e tratamento da dor crônica. Foram incluídas 52 pacientes, para as quais foram aplicados o questionário McGilI de dor e a Escala Analógica Visual (EAV), além de instrumento específico, baseado na escala Likert, contendo 24 afirmativas divididas em três categorias: informação, liberdade e competência. Os resultados mostraram mediana com escores acima de 60% do valor máximo para as três categorias. A idade, duração da dor, intensidade da dor pela Escala Analógica Visual (EAV) e pelo questionário de dor MCGilI apresentaram coeficiente de correlação de Spearman (r) 60% of maximum index for Information, Competence and Freedom. Age, length and intensity of pain (VAS and MPQ) weren\'t found be significantly correlated to any of the three categories (Spearman index r 0,6). Occupation, marital status and salaries didn\'t influence the scores of the three categories. Patients with low leveis of schooling presented lower scores of Information and Competence related to patients with higher schooling (p<0.05). Then, schooling levei influenced autonomy of chronic pelvic pain patients

Alta a pedido contra indicação médica sem iminente risco de morte

Resumo O atendimento à solicitação pelo paciente de alta a pedido contra indicação médica, sem risco iminente de morte, nada mais é do que garantir a autonomia desse paciente. Entretanto, não se trata de tema pacífico. O objetivo deste trabalho foi caracterizar a conduta do médico diante da alta a pedido. Realizou-se estudo de caso qualitativo, a partir de entrevistas individuais semiestruturadas com médicos assistentes de hospital público universitário. Foram realizadas oito entrevistas, gravadas e transcritas, e os dados, trabalhados por análise de conteúdo. Concluiu-se que os entrevistados consideram importante esclarecer o paciente acerca dos riscos de sua decisão, que deverá ser respeitada caso a mantenha; reconhecem também a relevância da documentação de alta e a impossibilidade de emitir receita quando não há alternativa cientificamente reconhecida. Evidencia-se, ainda, a preocupação do médico quanto às implicações legais de atender ao pedido do paciente

Implementation of the Street Outreach Office in the perspective of health care

ABSTRACT Objective: To report the experience of implementation of a clinical equipment of health care production to homeless people, denominated Street Outreach Office. Method: Experience report in the city of Rio de Janeiro, Brazil. Results: The Street Outreach Office implementation resulted from a demand for health care practices for homeless people. This implementation had intersectoral articulations, causing health professionals to carry out street care practices, which led them to strive for public policies, to rethink their actions in order to increase the resolution of care to this population. Conclusion: We should emphasize the importance of health professionals to reinvent their practices, daily, seeking partnerships and acquisition of new knowledge in order to achieve results that can reduce the demands of these individuals throughout their life routes

Dental and medical advertising: comparative analysis of the rules of professional conduct

In health care professional activities, advertising is an issue that raises serious discussions and is the cause of some ethical suits in professional entities, since every advertising should follow the provisions of the Code of Professional Responsibility. Therefore, this research study aimed at analyzing, comparing and discussing articles related to advertising and marketing, considering the current regulations from dental and medical entities. In Dentistry, this subject is ruled by the Code of Professional Conduct, Chapter XVI, ‘From advertising and marketing’. In Medicine, information is found in two regulations and in several chapters of the Code of Medical Ethics and in Resolution No. 1.974/2011 of the Federal Council of Medicine, which establishes the guiding criteria for medical advertising. The three regulations present articles that refers to participation in mass media, required information in advertisements, use of sensationalism and self-promotion, and publishing of unproven specialties and titles, highlighting the importance of these topics. The medical regulation also includes participation in publishing ads of manufacturing companies and an exclusive committee to deal with advertising and marketing issues, topics that are not considered in the dental regulation

Uso do spray de lidocaína em histeroscopia diagnóstica

OBJETIVO: determinar a eficácia do spray de lidocaína a 10% aplicado no colo uterino antes da execução da histeroscopia diagnóstica para reduzir a dor e o desconforto causados pelo exame. MÉTODOS: Participaram do estudo 261 pacientes atendidas consecutivamente, entre março de 2004 e março de 2005. As pacientes foram randomizadas para dois grupos: um grupo recebendo aplicação tópica do spray de lidocaína (grupo lidocaína) e outro não recebendo nenhuma medicação antes do procedimento (grupo controle). Trinta miligramas de lidocaína spray a 10% foram aplicados na superfície do colo uterino, sendo a histeroscopia iniciada cinco minutos depois. Imediatamente após o final do procedimento a paciente respondeu um questionário sobre dor e quantificou a intensidade da dor, em centímetros, usando uma escala analógica visual não graduada. Os testes t não pareado, Mann-Whitney e chi2 foram aplicados na análise estatística, com nível de significância de 0,05. RESULTADOS: não houve diferença entre os grupos quanto à idade, paridade ou porcentagem de pacientes na menacme ou menopausa, ou quanto à indicação do procedimento e os achados histeroscópicos. Uma biópsia foi realizada em 57 das 132 pacientes no grupo lidocaína, e em 48 das 129 do grupo controle (p=0,96). O escore médio de dor foi 4,3±2,9 no grupo lidocaína, e 3,9±2,5 no grupo controle (p=0,2). Diferença no escore médio de dor foi observada somente na comparação entre pacientes na menacme e menopausa recebendo ou não a lidocaína spray, com p=0,01 e 0,04, respectivamente. CONCLUSÕES: o uso da lidocaína spray durante a histeroscopia diagnóstica não minimiza o desconforto e a dor das pacientes, e não deve ser utilizada
