The efficacy of extensive resection on prolonging survival for patients with glioblastoma (GBM) is controversial because prior studies have included tumors with dissimilar resection capabilities. The true isolated effect of increasing resection on survival for GBM therefore remains unclear. ⋯ This is the first study to evaluate RV and EOR in a more uniform population of patients with tumors of similar surgical capabilities. This study shows that achieving a decreased RV and/or an increased EOR is independently associated with survival and recurrence in those patients with tumors with similar resection capacities.

X-linked dystonia-parkinsonism (XDP) is a progressively debilitating movement disorder that begins with focal dystonia and eventually generalizes. It exclusively affects Filipino inhabitants of the island of Panay. We report a case of XDP successfully treated by deep brain stimulation (DBS) and review the literature. ⋯ The published experience with globus pallidus internus DBS for XDP has been very positive to date. Although long-term follow-up data are needed, early results provide optimism for patients with this debilitating disorder.

Surgical decompression for optic neuropathy from carotid artery ectasia: case report with technical considerations.
Symptomatic compression of the optic nerve (ON) through its intracranial course or within the orbit may occur at several locations by abnormalities of adjacent soft tissue, bony, or vascular structures. Compressive optic neuropathy secondary to vascular ectasia is a rare phenomenon. ⋯ We present a patient with severe monocular visual loss and significant anatomic displacement of the ON by an ectatic internal carotid artery-ophthalmic artery complex with dramatic and rapid visual improvement after surgical decompression. Complete untethering of the nerve and total cessation of transmitted pulsatility may not be necessary for symptomatic improvement. Optic nerve contact or displacement by the ipsilateral carotid artery is common in asymptomatic patients, therefore ruling out other etiologies of monocular visual loss before surgical decompression is paramount.

Safe and complete surgical excision of carotid plaque in carotid endarterectomy (CEA) is essential for preventing postoperative embolic stroke and restenosis. We considered the dissection plane for the plaque according to pathological findings of carotid atherosclerosis. We report our experiences with inner-intimal dissection in CEA. ⋯ Microsurgical interintimal dissection could accomplish good surgical outcome, including absence of significant early restenosis.
