Publication rate can indirectly assess the quality of research presented in scientific meetings. Considering presentations at orthopedic surgery and neurosurgery meetings, 10.5-66% of abstracts are published in scientific journals. Publication rate of abstracts presented at CSS Meetings is unknown. The objective of this study was to evaluate the publication rate of abstracts presented at the Canadian Spine Society(CSS) Annual Meetings from 2005to2014. ⋯ The CSS scientific meeting maintain along the years a steady high quality research presentations as manifested by its significant publication rate(54.8%) in medical journals with mean IF of 3.73. In comparison with other spine scientific meetings, publication rates of abstracts presented at CSS meeting is amongst the highest.

Postoperative visual recovery is a major concern after transsphenoidal surgery. Optical coherence tomography (OCT) can visualize the anatomy of the retina, and retinal nerve fiber layer (RNFL) thinning reflects loss of optic nerve axons. Visual-evoked potential (VEP) is an electrophysiological response that confirms the nerve conductance. Therefore, these factors reflecting the optic nerve condition may be closely associated with the visual outcome after transsphenoidal surgery. ⋯ OCT is a useful diagnostic modality to assess optic nerve condition, and RNFL thickness of the temporal quadrant is correlated with visual outcome after transsphenoidal surgery. Patients with severe visual disturbance may still achieve visual recovery, so surgery should be considered even if optic disc atrophy is evident.

A single-institution case series is reported and a review of the literature on the outcomes of digital nerve gap reconstruction with the NeuraGen type 1 collagen nerve conduit (Integra Life Sciences, Plainsboro New Jersey, USA) and the Avance Nerve Graft (Axogen Inc., Alachua, Florida, USA) is presented. ⋯ Nerve conduits and processed nerve allografts offer convenient off-the-shelf options for digital nerve gap repair. Both techniques offer effective means of reconstructing a digital nerve gap <2.5 cm at a minimum of 12 months of follow-up. Future prospective randomized large sample size studies comparing nerve conduits with allografts are needed to perform subgroup analyses and to define their exact role in digital nerve injuries.

Review Meta Analysis
Efficacy and Safety of Hypofractionated Stereotactic Radiotherapy for Recurrent Malignant Gliomas: A Systematic Review and Meta-analysis.
The current treatment for patients with relapsed malignant glioma (MG) remains unsatisfactory. Use of hypofractionated stereotactic radiotherapy (HFSRT) for recurrent MG has shown some encouraging results and may be a viable option. ⋯ The present evidence suggests that HFSRT is an efficacious and safe treatment approach to treat patients with recurrent MG. However, the retrospective and observational nature of the studies included in our systematic review and meta-analysis restricted formation of more solid conclusions. Thus, well-designed prospective controlled trials are warranted to further define the therapeutic role of HFSRT for recurrent MG.
