To evaluate the incidence and risk factors of postsurgical site infections (SSIs) in elective neurosurgical procedures in patients treated with an ultrashort antibiotic protocol. ⋯ The present series reports a low incidence of SSIs for elective neurosurgery, even for high-risk complex craniotomies performed for tumor removal. Given that an antibiotic protocol prolongation was used to pretreat any early signs of infection and external communication, the protocol was appropriate for the case mix. The two identified risk factors (surgical duration > 2 hours and middle-aged patients [16-50 yr]) may be indicators of other factors, such as the level of surgical complexity and poor neurological outcome.

Ion transporters play pivotal roles in cancer cell migration in general and in glioblastomas (GBMs) in particular. However, the specific role of Na/K-ATPase (the sodium pump) and, in particular, its alpha1 subunit, has remained unexplored in GBMs. ⋯ Inhibition of the Na+/K+ -ATPase alpha1 subunit in human GBM cells impairs both cell migration and cell proliferation.

Lumbar facet joint angle and its importance on joint violation in lumbar microdiscectomy.
We investigated facet joint angle at the level of the nucleus pulposus in herniated disks and documented the importance of this angle in preserving articulation and surgical view in patients undergoing lumbar microdiscectomy. ⋯ The angle of the lumbar facet joint is important to protect articulation during lumbar microdiscectomy, and violating the facet joint may affect early postoperative pain. A facet angle of less than 35 degrees does not allow for a safe surgical corridor in which to use instruments, nor does it provide a satisfactory view for the surgeon.

Well-documented case reports of the rapid formation and rupture of de novo aneurysms of the posterior circulation are rare. ⋯ We review the pertinent literature and discuss possible reasons for the development and rupture of this second aneurysm.

We prospectively investigated the predictive value of diffusion tensor tractography for motor functional outcome in a case series of patients with intracerebral hemorrhage. ⋯ Motor functional outcome in patients with intracerebral hemorrhage can be predicted by measuring FA values using diffusion tensor tractography.
