This study evaluates the efficacy of linear accelerator (LINAC) radiosurgery using micro multi-leaf collimator technique (μMLC) in the treatment of a consecutive series of patients with vestibular schwannomas. ⋯ LINAC radiosurgery using a micro multi-leaf collimator for vestibular schwannomas smaller than 3 cm is effective in yielding a high local tumor control, whereas the treatment-related morbidity remains low.

Quasi-moyamoya disease (MMD) is characterized by moyamoya vasculopathy and well-recognized comorbidity. Whether the recently identified MMD susceptibility gene variant, p.R4810K (rs112735431), is associated with quasi-MMD remains unclear. ⋯ The p.R4810K variant was associated with atherosclerotic and autoimmune quasi-MMD in a Chinese population, and a lower prevalence of this variant in patients with quasi-MMD compared with patients with MMD was observed.

Review Meta Analysis
Spinal diffusion tensor imaging in the evaluation of pre- and post-operative severity in cervical spondylotic myelopathy: A systematic review of the literature.
Diffusion tensor imaging (DTI) is increasingly investigated as a potential diagnostic and prognostic tool for symptomatic degenerative cervical pathology; however, it is yet to be validated for this purpose. ⋯ DTI is associated with preoperative severity and postoperative outcomes in CSM patients, suggesting that DTI may become useful in identifying those most likely to benefit from operative intervention (Level 3 Evidence). Prospective trials with standardized DTI acquisition techniques and patient selection are required for higher-level evidence.

In addition to size and location, the morphology of intracranial aneurysms has been proposed to predict rupture. This study was undertaken to compare morphologic features between ruptured and unruptured aneurysms and identify those associated with greater risk of rupture. ⋯ Morphology might have an independent predictive value of aneurysm rupture. Risk of rupture might increase according to extent of morphologic change. Prospective studies will be necessary to evaluate the influence of aneurysm morphology on natural history.

Multicenter Study Controlled Clinical Trial
Patients' Preference of the Timed Up and Go (TUG) Test or Patient-Reported Outcome Measures (PROMs) Before and After Surgery for Lumbar Degenerative Disc Disease.
The Timed Up and Go (TUG) test, as a measure of objective functional impairment in lumbar degenerative disk disease (DDD), complements patient-reported outcome measures (PROMs) of subjective functional impairment. ⋯ The TUG test is preferred over a battery of PROMs by 60%-70% of patients with lumbar DDD not only in the preoperative, but also in the postoperative, setting. High functional disability does not result in avoidance of the TUG test, and repeated assessments lead to higher preference.
