ABSTRACT
Emergency departments (EDs) are alert to the possibility of stroke and the need for early interventions to improve long-term clinical outcomes. However, new-onset hemiparesis in pediatric patients with leukemia may be due to a number of different etiologies, including most common side effects from chemotherapeutic agents. We present a case of a 15-year-old boy with pre-B acute lymphoblastic leukemia on chemotherapy, having recently received a high-dose methotrexate infusion in addition to intrathecal methotrexate therapy, who presented to our ED with acute right-sided hemiparesis. He was initially suspected as having a possible ischemic stroke. Magnetic resonance imaging (diffusion-weighted and fluid-attenuated inversion recovery sequence) demonstrated focal areas of diffusion restriction, an early sign of delayed-onset methotrexate neurotoxicity. Our patient received appropriate supportive care and leucovorin rescue with gradual clinical recovery, after a prolonged hospitalization and acute care rehabilitation over the course of several months. Our case illustrates the need for ED providers to consider methotrexate neurotoxicity in pediatric oncology patients presenting with acute neurologic changes.

The study describes the creation and implementation of a culturally appropriate cancer education intervention, and assesses its efficacy among American Indians in a community with documented cancer-related disparities. Education workshops were developed and conducted on three western South Dakota reservations and in Rapid City by trained community representatives. Over 400 individuals participated in the 2-h workshops. Participants answered demographic questions, questions about previous cancer screening (to establish baseline screening rates), and completed a pre- and post-workshop quiz to assess learning. Participants demonstrated significant increases in cancer screening-related knowledge levels. Surveys reveal that participants found the information of high quality, great value and would recommend the program to friends. Pre-workshop data reveals cancer screening rates well below the national average. Workshop participants increased their knowledge about cancer etiology and screening. This intervention may represent an effective tool for increasing cancer screening utilization among American Indians.
