Abstract

Stereotactic radiotherapy using linear accelerators (Linac-knives) is a promising approach for treatment of metastatic brain tumors, arterio-venous malformations, and benign brain tumors. The advantages of the linac-knife over the Gamma knife are its capacity for stereotactic fractionated radiotherapy and to extend the indication for head and neck tumors and cervical spinal tumors.

GLUT1 endothelial reactivity distinguishes hepatic infantile hemangioma from congenital hepatic vascular malformation with associated capillary proliferation.

Hepatic vascular lesions in pediatric patients have overlapping definitions and a plethora of confusing terminology. The so-called hepatic infantile hemangioendothelioma (IHE) frequently coexists and shares some biological features with cutaneous juvenile hemangioma (CJH). To clarify the nature of hepatic vascular lesions in pediatric patients and to investigate the association between IHE and CJH, we reviewed the clinical features, imaging findings and histopathology of 19 cases of hepatic vascular lesions diagnosed at our institution over the last 33 years. Immunohistochemical stains for a battery of endothelial markers, including GLUT1, were performed. Our results indicate that there are two fundamentally different hepatic vascular lesions in infants and young children: GLUT1-positive hepatic infantile hemangioma (HIH) and GLUT1-negative hepatic vascular malformation with capillary proliferation (HVMCP). The finding of consistent GLUT1 immunoreactivity of endothelial cells in HIH not only offers a powerful tool to distinguish HIH from HVMCP, but also provides immunophenotypic evidence of the similar biological origins of CJH and HIH.

The use of evoked potentials in intraoperative neurophysiologic monitoring.

Although not universally adopted, the growing body of literature provides strong evidence of the clinical utility of IOM in a variety of cerebrovascular surgical and endovascular procedures. The Therapeutics and Technology Subcommittee of the American Academy of Neurology and Fisher et al concluded that the following are useful and noninvestigational: 1. EEG, compressed spectral array, and SSEP in CEA and brain surgeries that potentially compromise cerebral blood flow, 2. BAEP and cranial nerve monitoring in surgeries performed in the region of the brainstem or inner ear, 3. SSEP monitoring performed for surgical procedures potentially involving ischemia or mechanical trauma of the spinal cord. They also came to the conclusion that although promising, motor EPs and visual EPs are still investigational. Further investigation, especially in the area of outcomes research and cost-effectiveness, is required before IOM can become standard practice.
