Clinicopathological considerations in patients with lumbosacral extraforaminal stenosis.
Lumbosacral extraforaminal stenosis is not uncommon among patients being treated for radicular symptoms. Patients who had lumbosacral extraforaminal stenosis were reviewed, and cadaver dissection was used to determine the anatomy of extraforaminal lesions. A total of 167 patients with lumbosacral spinal stenosis who underwent surgery from March 2004 to February 2006 were reviewed retrospectively. ⋯ No major complications or recurrences were observed during follow-up. Therefore, lumbosacral extraforaminal stenosis should be included in the differential diagnosis of lumbar radicular pain. A precise diagnosis using MRI is important, and complete decompression with an understanding of the extraforaminal anatomy is required.

There is an increasing amount of published literature supporting the use of decompressive craniectomy in the management of raised intracranial pressure and it appears that this procedure will become established as a method by which intracranial hypertension can be treated. While technically fairly straightforward, a decompressive craniectomy is not without complications. A further complication is presented here, which has not been previously reported. ⋯ He suffered further cerebral injury and subsequently died. Following a detailed review of the case a number of recommendations were made and a specific post-decompressive craniectomy operational policy for the assessment and management of these patients was implemented. While we accept that these particular guidelines are specific to a particular institution, this case highlights the need to view these patients as a particularly high risk and recommend that institutions review or establish a specific policy regarding their management.

The neuroprotective effect of N-acetylcysteine (NAC), a sulfhydryl-containing antioxidant, on experimentally induced subarachnoid hemorrhage (SAH) in rats was assessed. NAC was administered to rats after the induction of SAH. Neurological deficits and brain edema were investigated. ⋯ We found that NAC markedly reversed the SAH-induced neurological deficit and brain edema. We further investigated the mechanism involved in the neuroprotective effects of NAC on rat brain tissue and found that NAC significantly increased CuZn-SOD and GSH-Px activity and decreased MDA content in the SAH brain. NAC has the potential to be a novel therapeutic strategy for the treatment of SAH, and its neuroprotective effect may be partly mediated via enhancing the activity of endogenous antioxidant enzymes and inhibiting free radical generation.
