PURPOSE Children who undergo standard therapy for renal tumors are at an increased risk for treatment sequelae such as congestive heart failure, abnormal trunk development, and secondary malignancies. Therefore, research on the use of novel chemotherapeutic agents with fewer side effects is justified. Recent experimental evidence suggests that growth factor(More)
Gene expression profiling of metastatic brain tumors from primary lung adenocarcinoma, using a 17k-expression array, revealed that 1561 genes were consistently altered. Further functional classification placed the genes into seven categories: cell cycle and DNA damage repair, apoptosis, signal transduction molecules, transcription factors, invasion and(More)
The need for more accurate prediction of the biological behavior of brain tumors has lead to the use of immunohistochemical methods for assessment of proliferating cell nuclear antigens such as Ki-67. There is a variable association of glioma Ki-67 labeling index with patient survival. Brain invasion by individual tumor cells also defines biological(More)
OBJECT Extensive invasion and angiogenesis are hallmark features of malignant gliomas. Communication between malignant glioma cells and surrounding astrocytes occurs, resulting in transformation of the astrocytic phenotype. In the present study, the authors examined whether malignant glioma cells and vascular endothelial cells (VECs) communicate through the(More)
BACKGROUND AND IMPORTANCE The abuse of cocaine can lead to significant destruction of midline craniofacial structures. This process occurs secondary to myriad mechanisms, including ischemic necrosis, irritation by chemical adulterants, and direct trauma during its administration. Coupled with a prolonged chronic infection of intranasal and anterior skull(More)
In the past several decades methods have been developed to stabilize the subaxial cervical spine both posteriorly and anteriorly. Methods of posterior stabilization have progressed from interspinous wiring, through facet wiring and sublaminar wiring, to the lateral mass screws with plates and rods that are in use today. Plates for anterior stabilization(More)
Kaposi sarcoma (KS) is one of the most common tumors in patients with human immunodeficiency virus (HIV), which characteristically presents with cutaneous lesions. The authors report a rare case of spinal KS with no cutaneous manifestation in a 32-year-old man with the acquired immunodeficiency syndrome who presented with abdominal pain. A computed(More)
Distal anterior inferior cerebellar artery (AICA) pseudoaneurysms are very rare lesions. Although cases have been previously reported, only a few have been reported as a result of vestibular schwannoma (VS) radiation, none have been reported as a result of VS resection, and only one has been reported as treated with parent vessel occlusion (PVO) with(More)
