Atypical teratoid/rhabdoid tumors of the central nervous system: clinical, radiographic and pathologic features.

INTRODUCTION: Atypical teratoid/rhabdoid tumors (ATT/RT) of the central nervous system (CNS) are uncommon malignancies of childhood with an aggressive course and a uniformly fatal outcome. METHODS: The medical records, radiographic images and pathologic files at the Rainbow Babies and Childrens Hospital over the previous 6 years were retrospectively reviewed. RESULTS: Eight children underwent surgery for CNS ATT/RT at our institution since 1996. There were 6 boys and 2 girls. Median age at presentation was 21 months. Four tumors had multifocal disease at the time of diagnosis. Six patients received multiagent chemotherapy including 3 patients with autologous bone marrow transplantation, and 6 patients received radiation therapy. Median survival was 9 months from the time of diagnosis. CONCLUSIONS: In spite of aggressive therapy, the prognosis for ATT/RT remains dismal. The search for effective treatment strategies will require a better understanding of the biology and molecular genetics of this tumor.

Sledding accidents in children: potential for serious injury, risk of fatality.

Though a pastime rarely considered rough or dangerous, sledding is not risk-free. The presentation of several serious injuries to Rainbow Babies and Children's Hospital in Cleveland, Ohio, led us to examine our emergency department and admitting records to determine the incidence of neurological injury among children involved in sledding accidents. We discovered 24 children who had sustained brain or spine injuries as sequelae to sledding mishaps during a 5-year period. The ages ranged from 3 months to 15 years. Injuries included multiple skull fractures, 2 epidural hematomas, 1 subdural hematoma, 1 odontoid fracture and 1 anoxic brain injury. There was 1 death. Twenty-one of 24 patients incurred their injuries by colliding with fixed objects. Both improvised crafts and models intended for sledding were involved in the injuries. Only 3 sleds possessed steering capability. Eight of the 9 children who sustained a serious neurosurgical injury were supervised by an adult. Only 2 children had received instruction before sledding. The lack of awareness of the potential for injury together with the dearth of instruction and lack of control over a vehicle dashing down a hill studded with obstacles can change a carefree pastime into a hazardous activity.
