We compared and evaluated percutaneous retrogasserian balloon compression (PBC) and Gamma Knife radiosurgery (GKRS) for treatment of trigeminal neuralgia (TN) in patients with multiple sclerosis (MS). ⋯ PBC and GKRS are effective techniques for treatment of TN in patients with MS. Fewer complications and superior long-term relief were associated with GKRS. We consider GKRS as the first option for the treatment of TN in patients with MS, reserving PBC for patients with acute, intractable pain.

The purpose of this study is to discuss the causes of implant migration after cervical arthroplasty with clinical cases. ⋯ The following situations should be considered in the prevention of dislocation and migration of the implant in cervical arthroplasty: protection of the structure of the end plate, selection of the appropriate implant size, and proper surgical construction. In the preoperative period, computed tomography scan may be useful for determining the implant size and details of the bone structure. Foreign body reactions or postoperative trauma may be a rare and unpreventable reason for prosthesis dislocation despite all of the preoperative and perioperative measures and well-made prosthesis designs.

Cytoarchitectural neuroimaging remains critical for diagnosis of many brain diseases. Fluorescent dye-enhanced, near-infrared confocal in situ cellular imaging of the brain has been reported. However, impermeability of the blood-brain barrier to most fluorescent dyes limits clinical utility of this modality. The differential degree of reflectance from brain tissue with unenhanced near-infrared imaging may represent an alternative technique for in situ cytoarchitectural neuroimaging. ⋯ We showed that unenhanced near-infrared reflectance imaging of fresh human cadaver brain can reliably identify and distinguish neurons and detailed cytoarchitecture of the cerebellum and substantia nigra.

To examine the influence of race, gender, and socioeconomic factors on presentations and outcomes of adult Chiari I malformations. ⋯ Significant differences in presentation of Chiari I malformation resulting from gender, race, and insurance status were quantified for the first time.
