CONTEXT: Squamous cell carcinoma arising from chronic lymphedema has only been reported in the literature 11 times (12 cases). Some aspects of its pathogenesis remain unclear and, for the first time, attention has been drawn to epidemiological data. CASE REPORT:A 90-year-old white female with chronic unilateral lower-limb lymphedema, secondary to trauma 20 years earlier, presented with a three-month history of a vegetating cutaneous lesion. There had not been any previous local ulceration. The tumor was completely excised and the histopathological analysis showed that it was an infiltrating squamous cell carcinoma. A literature review in the Medline (Medical Literature Analysis and Retrieval System Online) and Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde) databases using the MeSH (Medical Subject Heading) terms "Carcinoma, Squamous Cell" AND "Lymphedema" identified 112 references and found 12 similar case reports. RESUMOCONTEXTO: O crescimento de carcinoma de células escamosas a partir de linfedema crônico foi relatado apenas 11 vezes na literatura (12 casos).Aspectos sobre sua patogênese ainda não foram completamente elucidados e pela primeira vez chama-se atenção para os dados epidemiológicos.
-Background -Solid papillary-cystic pancreatic tumors have been recognized as a distinct neoplastic disease, whose incidence has increased in recent years with advancements in imaging technology. Case report -Woman 17-year-old consulted with a symptomatic giant homogeneous solid-cystic mass in the pancreatic tail, undergone a spleen preserving distal pancreatectomy, with excision of the splenic vessels. Histopathology revealed epithelium-lined pseudopapillary protrusions, without malignant change. The patient's postoperative course was uneventful. ConclusionSolid papillary-cystic pancreatic tumor has uncommon incidence and silent presentation, a high degree of suspicion on the part of the surgeon is warranted. In early diagnosis, complete resection is curative. The spleen should be preserved, if feasible.RESUMO -Introdução -Tumores sólido-cístico papilares têm sido reconhecidos como uma doença neoplásica distinta, cuja incidência tem aumentado atualmente em decorrências dos avanços em imaginologia. Relato do caso -Mulher de 17 anos, procurou atendimento médico em virtude de uma massa homogênea sólido-cística em cauda pancreática, e foi submetida a pancreatectomia distal com preservação do baço, apesar da excisão dos vasos esplênicos. Avaliação histológica revelou protrusões pseudopapilares revestidas de epitélio, sem degeneração maligna. A evolução clínica pós-operatória ocorreu sem complicações. Conclusão -Estes tumores têm que ser reconhecidos pelos clínicos, patologistas e radiologistas, e cirurgicamente ressecados com preservação do baço, conquanto apresentam prognóstico favorável.

Patients were allocated in relation to BMI in both groups (below or above 25 kg/m 2 ) and radiologists, in three groups according to their professional experience (less than five years, between five and 10 years and more than 10 years). The survey also assessed the influence of gender and time of disease progression using the median of 36 hours. Results Results ResultsResults Results: The sensitivity and specificity of abdominal ultrasonography for diagnosing appendicitis were 64.9 and 72% respectively. Gender, body mass index, length of experience of the radiologists in the three groups and time of onset of symptoms showed no significant differences in the establishment of sonographic diagnosis of acute appendicitis. Conclusion Conclusion Conclusion Conclusion Conclusion: The abdominal ultrasonography showed low sensitivity and specificity and little contribution to the diagnosis of acute appendicitis. Gender, physical constitution, the experience of the radiologist and time of onset of symptoms did not affect the outcome of the sonography.
DESCRITORESAdesivo. Trato gastrointestinal. Anastomose cirúrgica. Fístula.RESUMO -Introdução: Apesar dos refinamentos em cirurgia gastrointestinal, vazamentos anastomóticos persistem como grave problema, associados à morbidade e mortalidade elevadas e constituem a complicação mais temida. Na tentativa de prevenir e reduzir estas complicações, diversidade de técnicas de reforço anastomótico tem sido investigada e diversas medidas auxiliares têm sido desenvolvidas. Objetivo -Revisar os dados associados a aplicação de adesivos em cirurgia digestiva. Método -Revisão bibliográfica de artigos disponíveis no Medline/Pubmed utilizando-se os descritores: adesivo, trato gastrointestinal, anastomose cirúrgica e fístula. Foram selecionados os artigos mais atualizados sobre o assunto os quais utilizaram adesivos como estratégia para reduzir a morbidade e mortalidade relacionada à cirurgia digestiva. Conclusão -Adesivos teciduais parecem seguros na prática clínica e têm sido utilizados com crescente frequência em várias especialidades cirúrgicas em decorrência de suas propriedades hemostáticas e selante, ganhando cada vez maior aceitação por parte dos cirurgiões. Estudos sugerem que adesivos cirúrgicos podem reforçar e melhorar a cicatrização de anastomoses intestinais, elevando a pressão de ruptura e aumentando a força tênsil. Os potenciais efeitos deletérios teciduais destas substâncias podem limitar sua utilização. Em decorrência da heterogeneidade dos estudos e falta de evidência forte, novas pesquisas deverão ser desenvolvidas.ABSTRACT -Background -Despite refinements in the field of gastrointestinal surgery, anastomotic leakage still remains a serious problem associated with substantial morbidity and mortality and is the fearest life threatening complication in digestive surgery. To prevent or reduce these complications, a diversity of line reinforcement techniques have been investigated and several adjunctive measures have been developed. Aim -To review the data associated with the application of adhesives in digestive surgery procedures. Method -Review of papers available at Medline/Pubmed database using the follow headings: adhesive, gastrointestinal tract, surgical anastomosis, fistula. It was chosen recent articles on the subject which showed adhesives as strategy to reduce morbidity and mortality related to digestive surgery. Conclusion -Tissue adhesives appears to be safe in the clinical setting and are been used with increasing frequency in a variety of surgical field for its unique hemostatic and adhesive abilities, gaining increasing acceptance among surgeons. Studies suggest that surgical adhesive can be useful to reinforce and improve intestinal anastomotic healing, increase anastomotic bursting pressures and tensile strength. The potentially harmful tissue effects of the preparations might compromise the use of these substances. Because of the heterogeneity and lack of high level evidence, new studies have to be performed. ABCDDV/726 INTRODUÇÃOA busca por uma anastomose impermeável tem sido fato constante ...
Interactions among human beings are very complex. Using only an ethical code as reference to deal with moral conflicts is hardly ever enough. Responsibility ethics demand such a profound reflection as well as a discussion about human essence and its role in society. The responsibility of a surgeon is inherent in a profession based since its origin, not only on altruism and humanity, but also on compassion, courage and tolerance. The studies and the comprehension of these qualities as well as the transmission of these values to the students and to the surgery residents are essential for human education of these individuals. This essay offers to show that these essential virtues are strongly connected to the work the surgeon develops whereas his/her responsibility starts before the surgery - when one intends to act.
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.
