Review[Description of clinical thinking by the dual-process theory].
Clinical thinking is a very complex process that can be described by the dual-process theory, it has an intuitive part (that recognizes patterns) and an analytical part (that tests hypotheses). It is vulnerable to cognitive bias that professionals must be aware of, to minimize diagnostic errors.

Case ReportsReversible cardiotoxicity in a 54-year-old woman treated with trastuzumab.
We report a 54-year-old woman with an stage IIA (T2N0M0) RE and RP negative and HER2-positive ductal invasive breast cancer who developed a reversible cardiotoxicity associated with chemotherapy. After surgery, she received four cycles of doxorubicin and cyclophosfamide. Later, she used paclitaxel and trastuzumab. ⋯ Systolic function of the left ventricle was normal before the initial dosis of trastuzumab, but significantly worsened following the beginning of drug administration. Moreover, a clear improvement of heart function was observed soon after the daily dose of trastuzumab was reduced. Better knowledge of risk factors for cardiotoxicity related to chemotherapy, and longstanding surveillance with serial echocardiograms can avoid more severe cardiotoxicity by chemotherapy.
