Regimens of paclitaxel and carboplatin are reasonably tolerated and efficacy is promising
According to findings published in the Aug. 1 issue of the Journal of Clinical Oncology, weekly regimens of paclitaxel in combination with full doses of carboplatin is reasonably well tolerated and the efficacy results appear promising.

Appropriate use of psychostimulants in children with ADHD also has been shown to reduce the likelihood that these children will develop drug or alcohol use disorders when they reach adolescence and adulthood.  more
