Alterations in the gray matter volume in transient ischemic attack: a voxel-based morphometry study.
Several studies have emphasized that transient ischemic attack (TIA) patients suffered functional impairments, but whether underlying morphological alterations exist remains unclear. This study aims to detect possible gray matter volume (GMV) alterations in patients with TIA using voxel-based morphometry (VBM) method. ⋯ Transient ischemic attack patients showed widespread morphology atrophy in DMN, suggesting that, despite the absence of a cerebral infarction, ischemic injury may induce structural abnormalities and eventually contribute to functional impairments in TIA patients. Our results may provide a valuable basis for the pathophysiological mechanism related to the cognitive dysfunction of TIA from the view of brain morphology.

The association of HLA-DRB1 and HLA-DQB1 alleles with genetic susceptibility to multiple sclerosis in the Slovak population.
The aim of the present study was to assess the association between HLA-DRB1 and -DQB1 allele groups with the genetic predisposition to multiple sclerosis (MS) in the Caucasian Central European Slovak population. ⋯ This is the first study performed to analyse the association of HLA-DRB1/DQB1 with susceptibility to MS in Slovakia. The results of our study confirm that HLA class II alleles, genotypes and haplotypes are associated with MS risk.

Randomized Controlled TrialNeurosurgical tactile discrimination training with haptic-based virtual reality simulation.
To determine if a computer-based simulation with haptic technology can help surgical trainees improve tactile discrimination using surgical instruments. ⋯ Virtual computer-based simulators with integrated haptic technology may improve tactile discrimination required for microsurgical technique.

Clinical TrialGabapentin versus pregabalin in relieving early post-surgical neuropathic pain in patients after lumbar disc herniation surgery: a prospective clinical trial.
The roles of gabapentin and pregabalin are well established in the management of chronic neuropathic pain. Here, we investigated the effectiveness of pregabalin and gabapentin for treating acute neuropathic pain following lumbar discectomy. ⋯ Many patients may suffer from neuropathic pain in the early post-surgical period after lumbar discectomy. Gabapentin and pregabalin are anticonvulsant agents that may decrease perioperative central sensitization and early post-surgical neuropathic pain. Gabapentin and pregabalin effectively relieved neuropathic pain and prevented the conversion of acute pain to chronic pain at the 1-year follow-up after lumbar discectomy.

Morphological parameters related to ruptured aneurysm in the patient with multiple cerebral aneurysms (clinical investigation).
We evaluated the rupture risk of multiple cerebral aneurysms in aspects of various morphological parameters, and determined which parameter can be a reliable predictor as one aneurysm ruptured, and the others did not. ⋯ Several morphological parameters were investigated to predict a rupture in multiple cerebral aneurysms using 3D angiogram. The aspect ratio, size ratio type I, daughter sac, and parent-daughter angle were revealed as competent parameters.
