The out-of-body experience (OBE), during which a person feels as if he or she is spatially removed from the physical body, is a mystical phenomenon because of its association with near-death experiences. Literature implicates the cortex at the temporoparietal junction (TPJ) as the possible anatomic substrate for OBE. ⋯ We repetitively induced OBE by subcortical stimulation near the left TPJ during awake craniotomy. Diffusion tensor imaging tractography implicated the posterior thalamic radiation as a possible substrate for autoscopic phenomena.

The primary study objective was to develop a microsimulation model to predict preventable first-ever and recurrent strokes and mortality for a population of medically or surgically managed octogenarians with substantial (>60%) asymptomatic carotid artery stenosis and comparing an adherent with a real-world nonadherent best medical treatment (BMT) regimen subjected to sex. ⋯ In the present microsimulation, in real-world drug adherence, it was likely that a strategy of early endarterectomy was beneficial in octogenarians with significant asymptomatic carotid artery disease compared with BMT alone.

To study the influence of tumor location (cervical vs. thoracic; extramedullary vs. intramedullary) on predictive value of intraoperative myogenic motor-evoked potentials (iMEP) changes in patients undergoing surgery for spinal cord tumors. ⋯ A strong association was observed between worsening of iMEPs and postoperative new neurological deficits in patients with TIM tumor.

Nontraumatic subdural hematoma (NTSDH) is a common neurosurgical disease process, with mortality reported as high as 13%. Seizure has a known association with NTSDH, although patient outcomes have not previously been well studied in this population. The purpose of this study was to examine the relationship between in-hospital seizure and inpatient outcomes in NTSDH. ⋯ Seizure in patients with NTSDH correlates with significantly increased total LOS and increased mortality. Direct costs are similarly increased. Further studies accounting for effects of illness severity are necessary to validate these results.

To evaluate the feasibility of the supraorbital keyhole approach for suprasellar or intrasuprasellar Rathke cleft cysts (RCCs) under pure endoscopic visualization. ⋯ The supraorbital approach under pure endoscopic visualization provides a valuable optional minimally invasive access for suprasellar and intrasuprasellar RCCs. This approach combines the advantage of minimal invasiveness and improved visualization while avoiding the risk of cerebrospinal fluid leaks, rhinonasal complications, and gland injury. It is particularly suitable for those cysts with the normal pituitary gland occupying the whole or most part of sellar floor.
