| 1 | Re-bleeding events in patients with obscure gastrointestinal bleeding after negative capsule endoscopy显示文摘AIM: To investigate long-term re-bleeding events after a negative capsule endoscopy in patients with obscure gastrointestinal bleeding(OGIB) and the risk factors associated with the procedure.METHODS: Patients referred to Hospital Egas Moniz(Lisboa, Portugal) between January 2006 and October 2012 with OGIB and a negative capsule endoscopy were retrospectively analyzed. The following study variables were included: demographic data, comorbidities, bleeding-related drug use, hemoglobin level, indication for capsule endoscopy, post procedure details, work-up and follow-up. Re-bleeding rates and associated factors were assessed using a Cox proportional hazard analysis. The Kaplan-Meier method was used to estimate the cumulative incidence of re-bleeding at 1, 3 and 5 years, and the differences between factors were evaluated.RESULTS: The study population consisted of 640 patients referred for OGIB investigation. Wireless capsule endoscopy was deemed negative in 113 patients(17.7%). A total of 64.6% of the population was female, and the median age was 69 years. The median follow-up was forty-eight months(interquartile range 24-60). Re-bleeding occurred in 27.4% of the cases. The median time to re-bleeding was fifteen months(interquartile range 2-33). In 22.6%(n = 7) of the population, small-bowel angiodysplasia was identified as the culprit lesion. A univariate analysis showed that age > 65 years old, chronic kidney disease, aortic stenosis, anticoagulant use and overt OGIB were risk factors for re-bleeding; however, on a multivariate analysis, there were no risk factors for re-bleeding. The cumulative risk of re-bleeding at 1, 3 and 5 years of follow-up was 12.9%, 25.6% and 31.5%, respectively.Patients who presented with overt OGIB tended to rebleed sooner(median time for re-bleeding: 8.5 mo vs 22 mo).CONCLUSION: Patients with OGIB despite a negative capsule endoscopy have a significant re-bleeding risk; therefore, these patients require an extended follow-up strategy. | Pedro Magalhes-Costa Miguel Bispo Sofia Santos Gilberto Couto Leopoldo Matos Cristina Chagas | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，4： | 3 |
| 2 | Anabolic steroid-induced cardiomyopathy underlying acute liver failure in a young bodybuilder显示文摘Heart failure may lead to subclinical circulatory disturbances and remain an unrecognized cause of ischemic liver injury. We present the case of a previously healthy 40-year-old bodybuilder, referred to our Intensive-Care Unit of Hepatology for treatment of severe acute liver failure, with the suspicion of toxic hepatitis associated with anabolic steroid abuse. Despite the absence of symptoms and signs of congestive heart failure at admission, an anabolic steroid-induced dilated cardiomyopathy with a large thrombus in both ventricles was found to be the underlying cause of the liver injury. Treatment for the initially unrecognized heart failure rapidly restored liver function to normal. To our knowledge, this is the f irst reported case of severe acute liver failure due to an unrecognized anabolic steroid-induced cardiomyopathy. Awareness of this unique presentation will allow for prompt treatment of this potentially fatal cause of liver failure. | Miguel Bispo Ana Valente Rosário Maldonado Rui Palma Helena Glória Joo Nóbrega Paula Alexandrino | 2009 | World Journal of Gastroenterology2009，15，23： | 0 |
