Complex regional pain syndrome (CRPS) has been reported following spinal surgery, but its frequency after spinal surgery is unknown. The aim of this study was to determine the frequency of spinal surgery preceding CRPS and to examine these patients regarding the course of the disease and prognostic factors. ⋯ CRPS is a rare complication after spinal surgery, but spinal surgery precedes the onset of CRPS of the lower limb in almost one-third of the cases. The first typical symptoms of CRPS emerge within 2 weeks after spinal surgery.

The perception of the vertical is frequently shifted to the contralesional side in patients with hemispheric lesions, and this is amplified by spatial neglect. However, we do not know the specific influence of hemianopia and space of perception on this phenomenon. Here, we analyzed the respective influences of spatial neglect, hemianopia and hemispace on the subjective vertical in patients with right hemispheric stroke. ⋯ Patients showed a counter-clockwise deviation, and this was exaggerated by both neglect and hemianopia. In patients with neglect, the error was greater in the left hemispace. In conclusion, neglect and hemianopia had additive effects on the contralesional bias of the subjective vertical.

It is important to recognize acutely evolving ischemic stroke attributable to reactivation of varicella zoster virus vasculopathy since antiviral agents are effective. ⋯ Chronic neuralgic pain in a dermatomal distribution of an evolving central nervous system vasculopathy is an important clue to its recognition.

Unilateral facial weakness is common. Transcranial magnetic stimulation (TMS) allows identification of a conduction failure at the level of the canalicular portion of the facial nerve and may help to confirm the diagnosis. ⋯ These data shed light on the TMS-based diagnosis of peripheral facial palsy, an ability to localize the site of lesion within the Fallopian channel regardless of the underlying pathology.
