Elevated blood urea nitrogen/creatinine ratio is associated with poor outcome in patients with ischemic stroke.
Dehydration may impair cerebral oxygen delivery and worsen clinical outcome in patients with acute ischemic stroke (AIS). We evaluated if elevated blood urea nitrogen to creatinine ratio (BUN/Cr) as a marker of dehydration was associated with poor clinical outcome in emergency department (ED) patients presenting with AIS. ⋯ An elevated BUN/Cr ratio in patients with AIS is associated with poor outcome at 30 days. Further study is needed to see if acutely addressing hydration status in ED patients with AIS can alter outcome.

Case ReportsModified acrylic cranioplasty for large cranial defects.
To describe a novel technique for constructing polymethylmethacrylate (acrylic) cranioplasty to repair large cranial defects. ⋯ Our technique is quick and easy to perform, avoids thermal injury to the brain and produces a strong implant with excellent cosmesis even with large bony defects.

An easy adjustable method of ectatic vertebrobasilar artery transposition for microvascular decompression.
Microvascular decompression (MVD) of trigeminal neuralgia (TN) or hemifacial spasm (HFS) caused by an elongated, tortuous or enlarged vertebral or basilar artery has a higher rate of incomplete cure. ⋯ The vertebrobasilar artery transposition and fixation method used in the present study provided surgeons an easy and adjustable way to perform MVD safely and effectively.

A clinical analysis on microvascular decompression surgery in a series of 3000 cases.
Despite the microvascular decompression (MVD) has become a definitive treatment for trigeminal neuralgia (TN) and hemifacial spasm (HFS), not all of the patients have been cured completely so far and this sort of operation is still with risk because of the critical operative area. In order to refine this surgery, we investigated thousands MVDs. ⋯ A prompt recognition of the conflict site leads to a successful MVD. To facilitate the approach, the craniotomy should be lateral enough to the sigmoid sinus. The whole intracranial nerve root should be examined and veins or arterioles should not be ignored. For TN, all the vessels contacting the nerve should be detached. For HFS, the exposure should be medial enough to the pontomedullary sulcus.
