[Cardiac magnetic resonance imaging in patients with a suspected myocardial infarction and normal coronary arteries].
Patients hospitalized with suspected ST-segment elevation myocardial infarction (STEMI) who have normal coronary arteries (CAs) on invasive coronary angiography (ICA) may have an AMI or another acute cardiac disease that mimics it. ⋯ Cardiac magnetic resonance imaging allows a precise diagnosis of acute myocardial infarction in patients with angiographically normal coronary arteries.

Case Reports[Use of PET/CT for staging of Ewing's sarcoma. Report of one case].
The use of positron emission tomography with computed tomography (PET/CT) for adult cancer patients is widespread, however, its use in pediatric patients is limited by fear of radiation, monetary cost and lack of awareness of its greater sensitivity in the evaluation of some types of tumors. Ewing's sarcoma is one of the primary pediatric malignancies in which PET/CT with 18F-labeled fluorodeoxyglucose (18F-FDG) has demonstrated greater sensitivity in the evaluation of bone metastases compared to scintigraphy, as well as in the evaluation of treatment response. ⋯ A biopsy confirmed the presence of an Ewing sarcoma. The tumor was staged with PET/CT which showed multiple bone lesions not visible in previous studies.

[The general self-efficacy scale (GSES): Reevaluation of its reliability and validity evidence in Chile].
Self-efficacy is a psychological variable closely related to healthy behaviors. One of the most widely used instruments to measure this variable is the general self-efficacy scale (GSES). In Chile, the only psychometric study of this scale has important analytical limitations. ⋯ The GSES is an adequate scale to measure general self-efficacy in the Chilean population and allows unbiased comparisons based on sex or age.
