Capability of identifying red nuclei in different pulse sequences of regular 1.5-tesla magnetic resonance images.
To investigate the optimal pulse sequences of commonly used 1.5-tesla MRI for identifying the red nucleus (RN) to aid targeting of the subthalamic nucleus (STN). ⋯ T2FLAIR is an alternative to FSE-T2WI that can readily demarcate the RN to help target the STN.

Comparative StudyChanging practice patterns of deep brain stimulation in Parkinson's disease and essential tremor in the USA.
Randomized controlled studies have shown deep brain stimulation (DBS) to be an effective treatment for Parkinson's disease (PD). Outside of large-center studies, little is known about trends in DBS use in the USA. ⋯ Patients who underwent DBS in the 2007 sample were older and had more comorbidities than those in the 2000 sample; in-hospital complications remained low. Understanding trends in DBS is helpful in assessing how the technology is adopted and what relationships should be further explored.

Comparative StudyThe effect of intraventricular trajectory on brain shift in deep brain stimulation.
Brain shift during deep brain stimulation (DBS) surgery may compromise target localization. Loss of cerebrospinal fluid is believed to be the underlying mechanism, thus an intraventricular trajectory during DBS surgery may be associated with increased shift, in addition to other complications, such as intraventricular hemorrhage. ⋯ Intraventricular trajectories during DBS surgery do not appear to compromise safety or targeting accuracy.

Vagoglossopharyngeal neuralgia treated by microvascular decompression and glossopharyngeal rhizotomy: clinical results of 21 cases.
Microvascular decompression (MVD) and rhizotomy are all selected for treating vagoglossopharyngeal neuralgia (VGPN). Nonetheless, controversies still exist about their curative effect on VGPN. Here we evaluate the effectiveness of MVD together with rhizotomy of the glossopharyngeal nerve for the treatment of VGPN. ⋯ Intracranial vagoglossopharyngeal nerve MVD with glossopharyngeal rhizotomy is an effective and safe procedure to treat VGPN.
