No Laughing Matter: Nitrous Oxide for Transrectal Prostate Biopsy
Patient-adjusted nitrous oxide (N2O), commonly called laughing gas, did not reduce anxiety associated with transrectal prostate biopsy but significantly reduced pain as compared with standard anesthesia, a small randomized study showed. Scores on a standardized anxiety questionnaire, the primary endpoint, did not differ significantly between patients randomized to N2O or standard care. However, patents in […]
Paramagnetic Seeds: An Effective Option for Breast Lesion Localization
Paramagnetic seeds along with superparamagnetic iron oxide (SPIO) was an effective combination for nonpalpable breast lesion localization and sentinel lymph node detection (SLND), data from the MAGTOTAL trial in Sweden showed. The totally magnetic technique was equivalent to the use of guidewire and SPIO regarding re-excision frequency at 2.84% versus 2.87%, for a difference of […]
