Premorbid migraine history as a risk factor for vestibular and oculomotor baseline concussion assessment in pediatric athletes.
OBJECTIVEMigraine history has recently been identified as a risk factor for concussion and recovery. The authors performed a cross-sectional study examining baseline outcome measures on newly developed and implemented concussion assessment tools in pediatrics. The purpose of this study was to examine the effects of premorbid, diagnosed migraine headaches as a risk factor on vestibular and oculomotor baseline assessment in pediatric athletes. ⋯ CONCLUSIONSPediatric athletes diagnosed with migraine headaches reported higher baseline symptom provocation scores on the VOMS. Athletes with migraine headaches also performed worse on the K-D test, further illustrating the influence of premorbid migraine headaches as a risk factor for elevated concussion assessment outcomes at baseline. Special consideration may be warranted for post-concussion assessment in athletes with migraine headaches.

Mechanical thrombectomy using a Solitaire stent retriever in the treatment of pediatric acute ischemic stroke.
OBJECTIVE Mechanical thrombectomy using a Solitaire stent retriever has been widely applied as a safe and effective method in adult acute ischemic stroke (AIS). However, due to the lack of data, the safety and effectiveness of mechanical thrombectomy using a Solitaire stent in pediatric AIS has not yet been verified. The purpose of this study was to explore the safety and effectiveness of mechanical thrombectomy using a Solitaire stent retriever for pediatric AIS. METHODS Between January 2012 and December 2017, 7 cases of pediatric AIS were treated via mechanical thrombectomy using a Solitaire stent retriever. ⋯ The average modified Rankin Scale score was 1 at the 3-month follow-up. Subarachnoid hemorrhage after thrombectomy occurred in 1 case and that patient died 3 days postoperatively. CONCLUSIONS This study shows that mechanical thrombectomy using a Solitaire stent retriever has a high recanalization rate and excellent clinical prognosis in pediatric AIS. The safety of mechanical thrombectomy in pediatric AIS requires more clinical trials for confirmation. ABBREVIATIONS ACA = anterior cerebral artery; AIS = acute ischemic stroke; CTA = CT angiography; ICA = internal carotid artery; MCA = middle cerebral artery; mRS = modified Rankin Scale; mTICI = modified Thrombolysis In Cerebral Infarction; NIHSS = National Institutes of Health Stroke Scale; rt-PA = recombinant tissue plasminogen activator.

Accuracy of robot-assisted versus optical frameless navigated stereoelectroencephalography electrode placement in children.
OBJECTIVE The aim of this study was to compare the accuracy of optical frameless neuronavigation (ON) and robot-assisted (RA) stereoelectroencephalography (SEEG) electrode placement in children, and to identify factors that might increase the risk of misplacement. METHODS The authors undertook a retrospective review of all children who underwent SEEG at their institution. Twenty children were identified who underwent stereotactic placement of a total of 218 electrodes. Six procedures were performed using ON and 14 were placed using a robotic assistant. ⋯ Increased soft-tissue thickness, bone thickness, and younger age reduced accuracy at entry. There were no complications. CONCLUSIONS RA stereotactic electrode placement is highly accurate and is significantly more accurate than ON. Larger safety margins away from vascular structures should be used when placing deep electrodes in young children and for trajectories that pass through thicker soft tissues such as the temporal region. ABBREVIATIONS CTA = CT angiography; IQR = interquartile range; MEG = magnetoencephalography; ON = optical frameless neuronavigation; RA = robot-assisted; SEEG = stereoelectroencephalography.

Recent trends in North American pediatric neurosurgical fellowship training.
OBJECTIVE The goal of this study was to evaluate trends in pediatric neurosurgical fellowship training in North America. METHODS From a database maintained by the Accreditation Council for Pediatric Neurosurgery Fellowships (ACPNF), all graduates of ACPNF-accredited pediatric neurosurgery fellowships were identified, and an Internet search was conducted to determine sex, undergraduate and graduate degrees, location and dates of residency and fellowship training, current practice/employment environment, American Board of Neurological Surgery (ABNS) or Fellowship of the Royal College of Surgeons certification status, American Board of Pediatric Neurological Surgery (ABPNS) certification status, and extent of current pediatric-focused practice. The graduates were further studied to determine whether they had completed a neurosurgical residency at a program with an affiliated ACPNF-accredited pediatric neurosurgery fellowship program, and their residency training programs were further classified by whether the program was ranked in the top 50 by NIH funding awards. Each fellowship graduate’s current practice was also ranked in a similar fashion. RESULTS There were 391 graduates of ACPNF-accredited pediatric neurosurgery fellowship programs from 1993 to 2018. ⋯ Of all graduates practicing in the United States, 68% practice in academic settings. Ninety-five percent of graduating fellows who were ABNS board eligible were ABNS certified. CONCLUSIONS A study of the graduates of accredited pediatric neurosurgical fellowships from 1993 to 2018 has revealed a growth in the number of graduates from ACPNF-accredited fellowship programs over time. A substantial portion of graduates will practice at least some adult neurosurgery and not go on to obtain ABPNS board certification.

Comparative StudyComparison of head impact exposure in practice drills among multiple youth football teams.
Limiting contact in football practice can reduce the number of head impacts a player receives, but further research is needed to inform the modification of optimal drills that mitigate head impact exposure (HIE) while the player develops the skills needed to safely play the game. This study aimed to compare HIE in practice drills among 6 youth football teams and to evaluate the effect of a team on HIE. ⋯ Full-speed tackling and blocking drills resulted in the highest HIE. Reducing time spent on contact drills relative to minimal or no contact drills may not lower overall HIE. Instead, interventions such as reducing the speed of players engaged in contact, correcting tackling technique, and progressing to contact may reduce HIE more effectively.
