Hemorrhage, seizures, and dynamic changes of familial versus non-familial cavernous malformation: systematic review and meta-analysis.
Cerebral cavernous malformations (CCMs) may be familial or nonfamilial. This systematic review compared the natural history of CCMs in familial compared with nonfamilial cases. ⋯ Familial CCMs show higher dynamic changes than nonfamilial cases. However, the presence of actual dynamic changes needs further assessment in nonfamilial cases. CCMs demonstrate a low incidence of seizure. First-time seizure increases the chance of recurrent seizure. Seizure rate based on the location and type of the lesion should be investigated further.

Early versus delayed flow diversion for ruptured intracranial aneurysms: A meta-analysis.
The use and timing of flow diversion for aneurysmal subarachnoid hemorrhage is controversial. The objective of this study is to perform a meta-analysis and systematic review to compare overall complication rate between early versus delayed flow diversion for ruptured aneurysms. ⋯ This meta-analysis did not show a difference in overall complication rate between early versus delayed flow diversion for ruptured aneurysms. Early flow diversion for ruptured blister/fusiform/dissecting aneurysms carries a lower risk of aneurysm rerupture and overall complications as compared with that for ruptured saccular/giant aneurysms.

Carotid Revascularization in the Elderly: a Systematic Review and Meta-analysis.
Results from studies comparing carotid artery endarterectomy (CEA) with carotid artery stenting (CAS) in the elderly population are variable in the literature. The objective of this study was to investigate whether CEA or CAS is associated with a better safety profile in older adults (>80 years of age) for treatment of symptomatic and asymptomatic stenosis. ⋯ This study shows that CEA is associated with a statistically significant lower risk of 30-day stroke in the elderly population compared with transfemoral CAS with distal or proximal protection. No differences were noted in the rates of periprocedural TIA, MI, death, and cranial nerve injury between CEA and CAS in the original pooled analysis.

MicroRNA Expression Profiles, Target Genes and Pathways in Intervertebral Disc Degeneration; A Meta-analysis of Three Microarray Studies.
Determining the expression profile and target genes of microRNA (miRNA) would assist in determining the pathophysiologic pathways in intervertebral disk degeneration (IDD). The aim of this study was to determine the expression profile of miRNA in degenerated intervertebral disks compared with normal healthy intervertebral disks. ⋯ We found that the identified miRNAs through meta-analysis are candidate predictive markers for IDDs through different pathways.

Accuracy of Current Techniques for Placement of Pedicle Screws in the Spine: A Comprehensive Systematic Review and Meta-Analysis of 51,161 Screws.
Pedicle screws (PSs) are routinely used for stabilization to enhance fusion in a variety of spinal diseases. Although the accuracy of different PS placement methods has been previously reported, most of these studies have been limited to 1 or 2 techniques. The purpose was to determine the current accuracy of PS placement among 4 modalities of PS insertion (freehand [FH], fluoroscopy-assisted [FA], computed tomography navigation-guided [CTNav], and robot-assisted [RA]) and analyze variables associated with screw misplacement. ⋯ The OP data show that CTNav has the highest PS accuracy rates. Thoracic PSs were associated with lower accuracy rates; however, RA showed fewer breaches in the thoracic spine compared with FH and FA. Given the heterogeneity among studies, further standardized and comparative investigations are required to confirm our findings.
