The aim of this study was to investigate the effects of C5/6 cervical artificial disc replacement (CADR), discectomy and intervertebral fusion on adjacent inferior (C6/7) intervertebral space stress, and provide a basis for application of CADR. ⋯ The adjacent inferior intervertebral space stress in the CADR group was near to that of the intact group, without significant difference (p > 0.05). The stress in the discectomy group was significantly higher than in the intact group, and lower than in the interbody fusion group (p < 0.05 and p < 0.01, respectively). The stress in the interbody fusion group was significantly higher than in the intact and CADR groups, respectively (p < 0.01).

A case of plexiform neurofibroma of the penis is presented. It is a rare condition often found in association with congenital neurofibromatosis. This case is unique because of the accompanying lesion of the facial nerve above the right eye, an association not previously reported. The patient was managed effectively by adequate resection of the penile lesion.

This study investigates the change of endothelial cell morphology and function at the rabbit basilar bifurcations in response to sustained high blood flow after bilateral common carotid artery ligation. ⋯ This study is the first to present endothelial cell changes of basilar artery bifurcation in response to sustained high blood flow in rabbits. Endothelial cell impairment possibly initiates aneurysm formation.
