We performed this meta-analysis to compare the safety of unilateral with bilateral instrumented fusion in 2-level degenerative disorders of the lumbar spine. ⋯ Our meta-analysis establishes the immediate safety and significant lesser operative period of unilateral pedicle screw fixation in lumbar fusion. However, due to lack of evidence on complications like cage subsidence and adjacent segment disease, unilateral pedicle screw fixation cannot be recommended as an alternative to bilateral pedicle screw fixation for 2-level degenerative spinal disease. Our analysis established the lacunae in literature for high-quality evidence on the subject; hence we recommend further large multicenter studies with longer follow-up to arrive at a conclusion.

Review Meta Analysis
Surgical Outcomes with Midline Vs. Lateral Approaches for Cranial Base Chordomas: A Systematic Review and Meta-Analysis.
Cranial base chordomas are complex lesions centered on the clivus that surgically can be approached from either a midline or a lateral corridor. ⋯ The meta-analysis did not show any significant difference in GTR or recurrence rates between the midline versus lateral approaches. Tumor extension to different compartments did not affect the GTR or recurrence rates with either approach. In terms of complications, CSF leak rate was higher in midline approaches and cranial nerve palsy was higher in lateral approaches.

Traumatic brain injury (TBI) is the leading cause of morbidity and mortality worldwide. Several prognostic factors have been developed to predict functional outcomes and mortality rate in patients with TBI. Neutrophil-to-lymphocyte ratio (NLR) is an objective, available, low-cost, and reproducible indicator of inflammation. ⋯ Further, higher NLR value is in correlation with lower Glasgow Coma Scale scores. Thus its role as a complementary index to other factors, such as Glasgow Coma Scale, in predicting outcomes after TBI is under investigation. This review aims at gathering the most recent data on the prognostic value of NLR in patients with TBI.

Review Historical Article
A Forgotten Tale from the Great War: General Lorenzo Bonomo and the Birth of Italian War Neurosurgery.
Little is known of the advances in battlefield medicine achieved in Italy before and during the Great War. Some deserve wider recognition; this is especially true for the field of neurosurgery. There are a limited number of historical records currently available, fewer still in English, and most of the systematic investigations on field surgery have been in the form of monographs within science history reviews, which obviously lack a strictly clinical perspective. ⋯ Lorenzo Bonomo. His incredibly advanced and modern ideas had unfortunately been forgotten. He pioneered research in the ballistic and forensic medical fields, building on first-hand experience, as he performed surgeries himself before the conflict and even while on the frontline, actively working to improve the chances of survival for the Italian troops fighting in the Great War.
