Addendum to “In this issue…”
This note was received 2 months after the deadline for receipt of papers and editorials for publication in the December 2009 issue. The Editor was given 5 days to return these papers to the publisher with the lineup and comments. These are the remaining papers that were accepted for publication in Surgical Neurology after others were selected for publication in the new journal, World Neurosurgery, which has a new Editor and Editorial Board and has indicated that it is a renamed Surgical Neurology. Unfortunately, the volume of papers remaining makes the issue quite large for the reader when added to the number of papers selected for the regular December issue. I have placed these newly received papers in the usual order consisting of original papers, technical papers, case reports, letters to the editor, and book reviews and made some comments on a few selected papers. The limited time allowed did not permit comments on all the papers. This selection is not a reflection on the quality of the articles. Some highlights of these papers follow: Li et al from China found that when using a quantitative analysis technique for examining motor neurons that the number of nerves innervating the levator ani muscle in rats with spinal bifida occulta is less than in normal rats. This paper is significant in the developing knowledge of Chiari syndrome and its different manifestations now becoming more apparent with the publication of work in this area. This paper is followed by a case report by Hsu et al from the United States, describing the resolution of syringomyelia in a patient with tethered cord without the Chiari deformity in the posterior fossa, who also had coarctation of the aorta. Both represent the complexity of the syndrome. Patients with
Ehlers-Danlos syndrome, a genetic disorder of the connective tissue, have a high incidence of Chiari deformities with tethered cord (personal observations from the cases by Milhorat). The Chiari defects represent an evolving disease spectrum. A paper entitled “Association of Chiari malformation type 1 and tethered cord syndrome: preliminary results of sectioning the filum terminale” by Milhorat et al was published in the July 2009 issue of Surgical Neurology, describing detailed clinical observations on this subject. More information will be written on this topic in the coming years as clinicians realize the ever-expanding spectrum of phenotypic expression of this genetic disease of the developing embryo and its interrelationship with other genetic diseases including craniosynostosis. Pavesi et al from Italy report on the acute removal of ruptured grade I and II arteriovenous malformations (AVMs), indicating that the acute removal can be safe and effective. Hernesniemi et al have reported this acute approach to AVMs previously. The author has also done acute AVM surgery with good results, as has Dr Neil Martin at the University of California, Los Angeles. This approach is a break with the traditional delayed surgical treatment of ruptured cerebral AVMs and is a treatment that will become more widely practiced. Selch et al from the United States report on their experience with the use of radiosurgery for benign nerve sheath tumors of the spine as an alternative to surgery. Placing screws in the lateral mass of C1 is difficult. Simsek et al report on how freehand placement at surgery is facilitated by careful preoperative planning. Yan et al from China report on the use of a virtual reality 3-dimensional workstation to process imaging information on skull base tumors before surgery to select an appropriate surgical approach. It is called a Dextroscope. There are some interesting papers on new technology that may be useful in neurosurgery. Matsumura et al from Japan report on the use of a new microscope system that permits a higher magnification of ×50. They used this system for EC-IC bypass surgery.
