Gastrointestinal (GI) bleeding is a frequently encountered and very serious problem in emergency room patients who are currently being treated with anticoagulant or antiplatelet medications. There is, however, a lack of clinical practice guidelines about how to respond to these situations. The goal of this study was to find published articles that contain specific information about how to safely adjust anticoagulant and antiplatelet therapy when GI bleeding occurs.The investigators initiated a global search on the PubMed and Google websites for published information about GI bleeding in the presence of anticoagulant or antiplatelet therapy. After eliminating duplicate entries, the medical articles that remained were screened to narrow the sets of articles to those that met specific criteria. Articles that most closely matched study criteria were analyzed in detail and compared to determine how many actual guidelines exist and are useful.We could provide only minimal information about appropriate therapeutic strategies because no articles provided sufficient specific advice about how to respond to situations involving acute GI bleeding and concurrent use of anticoagulant or antiplatelet drugs. Only 4 articles provided enough detail to be of any use in an emergency situation.Clinical practice guidelines and also clinical trials for GI hemorrhaging should be expanded to state in which situations the use of anticoagulant or antiplatelet drugs should be suspended and the medications should later be resumed, and they should state the level of risk for any particular action.
Neutropenic enteritis (NE) or enterocolitis (NEC) is a rare, but potentially life-threatening side effect of neutropenia-inducing chemotherapy agents. Generally, its occurrence is attributed to leukemiaassociated chemotherapies. Two cases of NE have been reported after the appliance of pemetrexed for treatment of non-small cell lung cancers. To our knowledge, NE has never been reported due to treatment with pemetrexed for malignant pleural mesothelioma (MPM). We present a case of MPM in a 77-year-old male suffering from severe NE one week after the seventeenth cycle of pemetrexed in the course of maintenance therapy for MPM, which could be treated successfully with antibiotic coverage and supportive measures. Concomitantly the patient showed a severe hyperpigmentation of his entire integument sparing the palms of both hands and the soles of his feet. After exclusion of alternative causes of skin hyperpigmentation, a pemetrexed-induced cutaneous hyperpigmentation was assumed according to two previous case reports. A combination of both pemetrexed-induced side effects in one patient has not been reported to date.

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.
