Scientific advances have allowed for the identification of numerous tumor markers involved in chordoma pathogenesis. In the future, chordoma cell lines will be produced that silence or over-express these tumor markers. As we increase our understanding of the mechanism of chordoma tumor proliferation, we can expect the development of targeted drug therapies.

The MPT craniotomy is a worthwhile alternative to the standard pterional craniotomy. There were no instances of suboptimal operative corridors and clip applications when the MPT craniotomy was utilized in the treatment of unruptured middle cerebral artery and supraclinoid internal carotid artery aneurysms proximal to the terminal internal carotid artery bifurcation.

This study was designed to examine the influence of saline irrigation at different temperatures on adhesion/formation in the rat. Saline irrigation through a laparotomy incision was performed at the following temperatures: 30 degrees C, 34 degrees C, 37 degrees C, 40 degrees C, 45 degrees C, 50 degrees C, 55 degrees C, and 60 degrees C. The control group (Gc, n = 20) underwent laparotomy without irrigation. Adhesions were found in: 5/20 animals of the Gc (all slight); 6/20 of the 30 degrees C group (all slight); 6/20 of the 34 degrees C group (all slight); 6/20 of the 37 degrees C group (all slight); 12/20 of the 40 degrees C group (all slight); 12/20 of the 45 degrees C group (11 slight, 1 moderate); 14/20 of the 50 degrees C group (12 slight, 2 moderate); 18/19 of the 55 degrees C group (2 slight, 6 moderate, 10 marked); and 18/18 of the 60 degrees C group (1 moderate, 8 marked, 9 massive). These results indicate that saline irrigation below body temperature does not prevent adhesions whereas warmed saline encourages adhesion formation in the rat.

These studies emphasize the disadvantage of transplanting an organ of an individual with GBM. However, it should be noted that these cases do not make up a large percentage of overall transplantations, and donors with primary central nervous system malignancies also do not represent the whole pool of organs available.

An understanding of the diaphragmatic-costal and diaphragmatic-spinal attachments is key for the safe and effective implementation of diaphragm mobilization during the lateral and thoracoabdominal approaches to the spine.
