BACKGROUND Paradoxical cases of psoriatic lesions induced or exacerbated by anti-tumor necrosis factor (TNF)-α therapy have been reported more frequently in recent years, but data related to inflammatory bowel disease (IBD) are rare. A systematic literature review was performed to provide information about this adverse effect in patients with IBD who(More)
CONTEXT Adalimumab is a fully-human antibody that inhibits TNF alpha, with a significant efficacy for long-term maintenance of remission. Studies with this agent in Latin American Crohn's disease patients are scarce. OBJECTIVES The objective of this study was to outline clinical remission rates after 12 months of adalimumab therapy for Crohn's disease(More)
CONTEXT Several paradoxical cases of infliximab-induced or-exacerbated psoriatic lesions have been described in the recent years. There is disagreement regarding the need to discontinue infliximab in order to achieve the resolution of these adverse cutaneous reactions specifically in inflammatory bowel disease (IBD) patients. OBJECTIVE To systematically(More)
Due to shortage of time and limited availability of faculty surgeons to teach basic surgical skills during medical graduation, the search for alternative ways of simulated training with feedback is needed. The purpose of this study was to compare the simulated teaching of suture skills to novice medical students by senior medical students and by experienced(More)
BACKGROUND Because of ethical and medico-legal aspects involved in the training of cutaneous surgical skills on living patients, human cadavers and living animals, it is necessary the search for alternative and effective forms of training simulation. AIMS To propose and describe an alternative methodology for teaching and learning the principles of(More)
OBJECTIVE Although several inanimate bench models have been described for training of suture skills, so far, there is no ideal method for teaching and learning this skill during medical education. The aim was to evaluate whether bench model fidelity interferes in the acquisition of suture skills by novice medical students. METHODS 36 medical students with(More)
BACKGROUND The search for alternative and effective forms of training simulation is needed due to ethical and medico-legal aspects involved in training surgical skills on living patients, human cadavers and living animals. AIMS To evaluate if the bench model fidelity interferes in the acquisition of elliptical excision skills by novice medical students.(More)
Although therapy with tumor necrosis factor-alpha inhibitors (anti-TNF) provides beneficial effects in different immune inflammatory disorders, paradoxical cases of anti-TNF-induced psoriasis have increasingly been reported, mostly in the setting of rheumatologic diseases. To date, less than 50 cases of infliximab-induced psoriasis in inflammatory bowel(More)
PURPOSE To assess the acquisition of suture skills by training on ethylene-vinyl acetate bench model in novice medical students. METHODS Sixteen medical students without previous surgery experience (novices) were randomly divided into two groups. During one hour group A trained sutures on ethylene-vinyl acetate (EVA) bench model with feedback of(More)
