Gastrointestinal stromal tumour in Meckel's diverticulum
<p>Abstract</p> <p>Background</p> <p>Meckel's Diverticulum is the most commonly encountered congenital anomaly of the small intestine, occurring in approximately 2% of the population. Occasionally Meckel's diverticulum harbors neoplasms.</p> <p>Case presentation</p> <p>A 65 year old gentleman, presented with a pelvic mass. On exploratory laparotomy, it turned out to be gastrointestinal stromal tumour (GIST) arising from Meckel's diverticulum. Short history and review of literature are discussed.</p> <p>Conclusion</p> <p>Neoplasms occurring from Meckel's diverticulum, even though rare, should be considered as differential diagnosis of pelvic masses arising from bowel, wherever imaging modalities fail to give a definitive diagnosis.</p
Seropositivity to Cytomegalovirus, Inflammation, All-Cause and Cardiovascular Disease-Related Mortality in the United States
Studies have suggested that CMV infection may influence cardiovascular disease (CVD) risk and mortality. However, there have been no large-scale examinations of these relationships among demographically diverse populations. The inflammatory marker C-reactive protein (CRP) is also linked with CVD outcomes and mortality and may play an important role in the pathway between CMV and mortality. We utilized a U.S. nationally representative study to examine whether CMV infection is associated with all-cause and CVD-related mortality. We also assessed whether CRP level mediated or modified these relationships., 2006 (N = 14153) in the National Health and Nutrition Examination Survey (NHANES) III (1988–1994). Cox proportional hazard models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for all-cause and CVD-related mortality by CMV serostatus. After adjusting for multiple confounders, CMV seropositivity remained statistically significantly associated with all-cause mortality (HR 1.19, 95% CI: 1.01, 1.41). The association between CMV and CVD-related mortality did not achieve statistical significance after confounder adjustment. CRP did not mediate these associations. However, CMV seropositive individuals with high CRP levels showed a 30.1% higher risk for all-cause mortality and 29.5% higher risk for CVD-related mortality compared to CMV seropositive individuals with low CRP levels.CMV was associated with a significant increased risk for all-cause mortality and CMV seropositive subjects who also had high CRP levels were at substantially higher risk for both for all-cause and CVD-related mortality than subjects with low CRP levels. Future work should target the mechanisms by which CMV infection and low-level inflammation interact to yield significant impact on mortality

Tratamento cirúrgico das hérnias inguinais recidivadas: modificação da técnica de mc vay pelo uso da malha de polipropileno monofilamentar
O autor fez revisão da literatura, o que lhe permitiu afirmar que o tratamento cirúrgico das hérnias inguinais contribuiu para o desenvolvimento da cirurgia como um todo. Somente no final do século passado foi alcançado o ponto importante do progresso das técnicas operatórias. Um "fantasma continuou rondando" os pacientes operados de hérnia: a recidiva. Vários grupos de cirurgiões já demonstraram essa preocupação e, a partir de 1913, passou-se a pensar em colocação de prótese, visando substituir a fáscia transversal desgastada, nas hérnias recidivadas. Dentre os vários tipos de material de prótese, a malha de polipropileno monofilamentar - marlex®, - tomou-se o mais aceitável. Nesse trabalho propõe-se a modificação da técnica de Mc Vay pelo uso da malha de polipropileno monofilamentar marlex®, que, em 109 hernioplastias para hérnias recidivadas, seguidas durante vinte anos, resultou em recidiva zero
