RESUMO
OBJECTIVE: The objective of this study was to determine the rate of malignancy in incidentally detected T2 hyperintense hepatic lesions at breast MRI. METHODS: Incidental hepatic lesions identified during breast MRI, for which abdominal imaging was recommended, were retrospectively analyzed. RESULTS: Of the hepatic lesions, 97.3% were benign, and 2.7% were malignant, with a significant association between indication for the breast MRI and the malignancy status of the hepatic lesion (Fisher's Exact, Pâ¯<â¯0.0142). CONCLUSION: Our initial experience suggests the benign nature of incidentally detected T2 hyperintense hepatic lesions at breast MRI in women without a newly diagnosed breast cancer.

Ultrasound is playing an increasingly important role in medical student education. Although most uses of ultrasound have focused on learning purely anatomic relationships or augmentation of the physical examination, there is little documentation of the value of ultrasound as a learning tool regarding physiology alone or in association with anatomy. We devised an interactive learning session for first-year medical students using ultrasound to combine both anatomic and physiologic principles as an integration of gastrointestinal and vascular function. The incorporation of our activity, The Hunger Games, provides the foundation for a powerful integration tool for medical student education.

This meta-analysis evaluates the effect of hypnosis in reducing emotional distress associated with medical procedures. PsycINFO and PubMed were searched from their inception through February 2008. Randomized controlled trials of hypnosis interventions, administered in the context of clinical medical procedures, with a distress outcome, were included in the meta-analysis (26 of 61 papers initially reviewed). Information on sample size, study methodology, participant age and outcomes were abstracted independently by 2 authors using a standardized form. Disagreements were resolved by consensus. Effects from the 26 trials were based on 2342 participants. Results indicated an overall large effect size (ES) of 0.88 (95% CI = 0.57-1.19) in favour of hypnosis. Effect sizes differed significantly (p < 0.01) according to age (children benefitted to a greater extent than adults) and method of hypnosis delivery, but did not differ based on the control condition used (standard care vs. attention control).
