Although gamma knife radiosurgery is an established treatment option for trigeminal neuralgia, its role in the management of glossopharyngeal neuralgia is unclear. We report a case of glosspharyngeal neuralgia treated effectively with gamma knife radiosurgery, review the literature, and discuss the rationale supporting dose and target selection. ⋯ This clinical response provides encouraging evidence for the treatment of glossopharyngeal neuralgia with stereotactic radiosurgery and is consistent with previous reports. Further investigation is needed to define the role of stereotactic radiosurgery in the management of glossopharyngeal neuralgia.

Currently available stents for intracranial use usually are Neuroform (Boston Scientific/Target, Fremont, CA) and Leo (Balt, Montmorency, France) stents. We present the results of our initial experience in using the Leo stent to treat patients with wide-necked cerebral aneurysms. ⋯ Preliminary data demonstrated that the Leo stent is useful device for the treatment of patients with wide-necked aneurysms. In cases with tortuous cerebral vasculature, delivery and deployment may be technically challenging. Clinically significant complications are uncommon.

Many Virtual Environments require walking interfaces to explore virtual worlds much larger than available real-world tracked space. We present a model for generating virtual locomotion speeds from Walking-In-Place (WIP) inputs based on walking biomechanics. ⋯ We compared resulting speeds from Real Walking, GUD WIP, and LLCM-WIP via user study: The average output speeds for Real Walking and GUD WIP respond consistently with changing step frequency - LLCM-WIP is far less consistent. GUD WIP produces output speeds that are more locally consistent (smooth) and step-frequency-to-walk-speed consistent than LLCM-WIP.
