RESUMO

Although breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare disease, its incidence has been increasing. The aim of this study was to assess the risk of BIA-ALCL in women with breast implants. A systematic search was carried out in Pubmed, Scopus, ScienceDirect, LIVIVO, Cochrane Library, Google Scholar, and OpenGrey databases. The risk assessment of bias was based on the Newcastle-Ottawa Scale. The rarity of BIA-ALCL was a major limitation. Although we have found evidence of an increased risk of BIA-ALCL, further studies are needed to understand why some large samples did not present any case of the disease.

RESUMO

BACKGROUND: Hernia correction is a routinely performed treatment in surgical practice. The improvement of the operative technique and available materials certainly has been a great benefit to the quality of surgical results. The insertion of prostheses for hernia correction is well-founded in the literature, and has become the standard of treatment when this type of disease is discussed. AIM: To evaluate two available prostheses: the polypropylene and polypropylene coated ones in an experimental model. METHODS: Seven prostheses of each kind were inserted into Wistar rats (Ratus norvegicus albinus) in the anterior abdominal wall of the animal in direct contact with the viscera. After 90 days follow-up were analyzed the intra-abdominal adhesions, and also performed immunohistochemical evaluation and videomorphometry of the total, type I and type III collagen. Histological analysis was also performed with hematoxylin-eosin to evaluate cell types present in each mesh. RESULTS: At 90 days the adhesions were not different among the groups (p=0.335). Total collagen likewise was not statistically different (p=0.810). Statistically there was more type III collagen in the coated polypropylene group (p=0.039) while type I was not different among the prostheses (p=0.050). The lymphocytes were statistically more present in the polypropylene group (p=0.041). CONCLUSION: The coated prosthesis was not different from the polypropylene one regarding the adhesion. Total and type I collagen were not different among the groups, while type III collagen was more present on the coated mesh. There was a greater number of lymphocytes on the polypropylene mesh.

RESUMO Racional: A correção herniária é tratamento realizado rotineiramente na prática cirúrgica. O aprimoramento da técnica operatória e dos materiais disponíveis trouxe grande benefício na qualidade dos resultados cirúrgicos. A inserção de próteses para correção herniária é bem embasada na literatura e tornou-se o padrão de tratamento. Objetivo: Avaliar em modelo experimental dois tipos de próteses diferentes, de polipropileno e polipropileno revestido. Métodos: Foram inseridas sete próteses de cada tipo em ratos Wistar (Ratus norvegicus albinus) na parede abdominal anterior do animal em contato direto com as vísceras. Após o seguimento de 90 dias analisaram-se as aderências intra-abdominais, bem como avaliação por imunoistoquímica e videomorfometria do colágeno total, tipo I e tipo III. Também, fez-se análise histológica com hematoxylina-eosina para avaliação dos tipos celulares presentes em cada tela. Resultados: Aos 90 dias as aderências não foram diferentes entre os grupos (p=0,335). O colágeno total igualmente não foi estatisticamente diferente (p=0,810). O colágeno tipo III foi estatisticamente maior no grupo polipropileno revestido (p=0,039) enquanto o tipo I não diferiu entre as próteses (p=0,050). Os linfócitos foram estatisticamente mais presentes no grupo polipropileno (p=0,041). Conclusão: A prótese revestida não foi diferente da de polipropileno na variável aderência. O colágeno total e tipo I não foram diferentes entre os grupos enquanto que o colágeno tipo III foi mais presente na tela revestida. O número de linfócitos foi maior na tela de polipropileno.

RESUMO

PURPOSE: We evaluated the hypothesis that induced perioperative hypothermia (32 ± 1ºC) affects the redox balance in the tissue of colonic anastomosis in rats by modifying biochemical enzymatic and non-enzymatic markers related to oxidative stress. METHODS: Forty-eight male Wistar rats were randomly divided into eight experimental groups of six animals each and underwent laparotomy, sigmoid section and immediate anastomosis. Four groups were operated under normothermia (36 ± 1ºC), and the other four under hypothermia (32 ± 1ºC). The animals were reoperated on days 3, 7 and 14 postoperatively, and two groups underwent SHAM at 3 days. From the scar tissue samples, the activity of the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT) was evaluated, and the levels of non-enzymatic markers of oxidative stress, such as reduced glutathione (GSH) and lipid peroxidation, were measured by the thiobarbituric acid reactive substances (TBARS) assay. The means were compared between groups corresponding to each day of sampling and euthanasia. RESULTS: The hypothermic groups showed a significant reduction on the activity of SOD on day 7 postoperatively, on the activity of CAT on days 7 and 14 postoperatively and on the levels of GSH on day 7 postoperatively. The level of lipid peroxidation was increased in the hypothermia group on day 7 postoperatively and decreased on day 14 compared with the normothermic groups. CONCLUSION: Perioperative hypothermia reduced the activity of the antioxidant enzymes catalase and superoxide dismutase, glutathione levels and increased lipid peroxidation in the scar tissue of colonic anastomoses in rats.

RESUMO

Introdução: dispepsia representa queixa comum na prática clínica diária. É um conjunto variável de sintomas como dor ou queimação epigástrica, saciedade precoce ou plenitude pós-prandial, de acordo com os Critérios Diagnósticos Roma III. Associações entre esses sintomas, idade, sexo e achados endoscópicos sugerem diferentes prevalências. Faltam pesquisas com bases científicas para sistematizar quais pacientes devem ser submetidos à endoscopia. Objetivo: descrever a prevalência dos achados endoscópicos e relacioná-los às características dos pacientes com sintomas dispépticos submetidos à Endoscopia Digestiva Alta (EDA). Métodos: Estudo transversal, descritivo e analítico, realizado no HGCR (Hospital Governador Celso Ramos) em Florianópolis - SC. Foram analisados 450 laudos endoscópicos de pacientes que apresentaram como indicação dispepsia e/ou sintomas dispépticos para a realização de EDA. Coletou-se dados acerca da indicação, sexo, idade e achados à endoscopia, que foram analisados pelo teste Qui-quadrado e Fisher no software SPSS18.0. Este trabalho foi aprovado pelo Comitê de Ética da Unisul (Universidade do Sul de Santa Catarina). Resultados: a maioria dos laudos do estudo apresentou alterações à EDA, sendo o principal achado a gastrite enantematosa e/ou erosiva. Do total, a maioria pertencia a mulheres entre 30 e 49 anos. Associações de idade até 30 anos e EDA normal, assim como pacientes acima de 70 anos e câncer gástrico, foram estatisticamente significantes.


Introduction: dyspepsia is a common complaint in daily clinical practice. It is a variable set of symptoms, such as epigastric pain or burning, early satiety or postprandial fullness, according to Rome III. Associations between these symptoms, age, gender and endoscopic findings suggest different prevalences. There are insufficient researches with scientific bases to systematize which patients should undergo upper endoscopy. Objective: to describe the prevalence of endoscopic findings and relate to the characteristics of patients with dyspeptic symptoms undergoing upper endoscopy. Methods: crosssectional, descriptive and analytical study was carried out in a Hospital in Florianópolis-SC. We analyzed 450 endoscopic reports with dyspepsia as an indication and/ or dyspeptic symptoms for the realization of upper endoscopy. Data were collected on the indication, such as age, gender and endoscopic findings, which were analyzed by chi-square and Fisher tests in software SPSS 18.0. This study was approved by the Ethics Committee of Unisul. Results: most of the reports of the study presented findings in the endoscopy, the main findings were enanthematous and/or erosive gastritis. Of the total, the majority belonged to women between 30 and 49 years old. Associations between 30 years old or less and normal endoscopy, as well as, patients over 70 years and gastric cancer were statistically significant. Conclusion: the prevalence of upper endoscopy with some found in dyspeptic patients was high. Enanthematous and/or erosive gastritis was the most prevalent finding. Most patients were female, mean age of patients 45 years and the main dyspeptic symptom was epigastric pain. Associations between age and findings can be made.
