Patients' understanding of "informed consent" in plastic surgery.
To assess the patient's understanding of the informed consent form before and after plastic surgery. ⋯ Comprehension of informed consent was higher before surgery than after surgery (p=0.016; question 15). The higher the scholarity, the higher the comprehension (s=0.151; p=0.045) before surgery (question 4). For the other questions, it was not possible to find a difference in the pattern of understanding and in the association with the educational attainment level after surgery (s=0.180; p=0.046; question 1). CONCLUSIONS: The patients' level of comprehension of the details, outcomes, possible complications, and postoperative evolutions of surgical procedures, as stated by the informed consent form, is high.

Radiation therapy with elective lymph node irradiation for breast cancer: dosimetric study and impact on cardiovascular risk and second neoplasms.
The aim of this study was to perform dosimetric analysis of radiotherapy (RT) plans with or without elective nodal irradiation (ENI) and estimate whether the increase in mean doses (MDs) in the heart and lungs with ENI may lead to late side effects that may surpass the benefits of treatment. ⋯ ENI increases the heterogeneity and the doses at the lungs. When recommending ENI, the risks and benefits must be taken into account, considering the oncology factors and the plan of each patient. Special attention must be given to patients who smoke as ENI may lead to a significant increase in MD in the lung and the increased risk of radiation-induced lung cancer may surpass the benefits from this treatment.
