Review Meta Analysis
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.

Atlantoaxial instability (AAI) is a common cause of neurologic dysfunction and pain in patients with Down syndrome (DS), frequently requiring instrumented fusion of the upper cervical spine. Despite this, optimal treatment strategy is controversial. ⋯ Numerous fixation strategies exist for AAI in patients with DS. Using a combination of screws, rods, and wiring in appropriately selected patients may help reduce the high rate of surgical complications in these patients.

To the best of our knowledge, no previous study has assessed the neurosurgical publications from Africa. A bibliometric analysis was performed in the present study to evaluate the contribution of African authors in neurosurgical journals worldwide and to discuss the approaches that could be used to enhance the quantity and quality of publications on this issue. ⋯ African neurosurgeons will be able to meet the challenges of the new century with the appropriate use of its resources and staff, regardless of the difficulties they face. However, African neurosurgical research could be improved by teaching research methods and medical writing and should focus more on modern neurosurgical topics by highlighting continental particularities. African neurosurgeons should collaborate with each other (locally, regionally, and abroad) and with foreign centers for better quality research and international visibility.

Multicenter Study
Epidemiology of iatrogenic vertebral artery injury in cervical spine surgery: 21 multicenter studies.
The overall incidence of iatrogenic vertebral artery injury (IVAI) in cervical spine surgeries (CSSs) is reported to be 0.07%-1.4%. Although IVAI occurred during C1-2 fusion, there is no accurate information regarding the surgery-specific risk of IVAI. This study aimed to stratify incidence of IVAI by surgical method and evaluate the correlation between IVAI and its sequelae. ⋯ Overall incidence of IVAI in CSSs was 0.08%. C1-2 posterior fixation had the highest incidence of IVAI (1.35%). Although clinical results of IVAI can be highly variable, controlling risk factors of IVAI is important.
