In the last decade pediatric emergency medicine in Israel advanced to a stage of independent emergency pediatric departments. At the same time, injuries and childhood, trauma--a global health problem--became the main cause of mortality and emergency referrals in children over the age of one year. ⋯ The ED is a major site for the delivery of healthcare to children in Israel. One of every four children in the community is referred every year to an ED, and more than one-third of those referrals are due to trauma.

Cancer is a multi-step disease involving a series of genetic alterations that result in the loss of control of cell proliferation and differentiation. Such genetic alterations could emerge from the activation of oncogenes and the loss or malfunctioning of tumor suppressor gene activity. Our understanding of cancer has greatly increased through the use of DNA tumor viruses and their transforming proteins as a biological tool to decipher a cascade of events that lead to deregulation of cell proliferation and subsequent tumor formation. ⋯ The increased incidence of acquired immune deficiency syndrome and the use of immunosuppressive chemotherapy have dramatically raised the incidence of PML. The coincidental occurrence of malignant astrocytes and oligodendrocytes in PML patients, coupled with the induction of glioblastoma in JCV-infected nonhuman primates, provides intriguing speculation on the association between JCV and CNS malignancies. In this report we discuss clinical data and laboratory observations pointing to the direct involvement of JCV in cancer.
