Upper cervical spine fusion in the pediatric population

David W. Lowry, Ian F. Pollack, Brent Clyde, A. Leland Albright, P. David Adelson
1997 Neurosurgical Focus  
The outcomes of 25 pediatric patients who underwent upper cervical or occipitocervical fusion at the authors' institution since 1983 were reviewed. At a mean age of 9 years, the patients presented with spinal instability that was associated with os odontoideum in 11 cases, rotatory subluxation in five cases, odontoid fracture in two cases, atlantooccipital dislocation in two cases, and congenital atlantoaxial instability in five patients, four of whom had Down's syndrome (trisomy 21).

Fusion was achieved with the first operation in 21 of 25 patients; eventually it was attained in all but one. Four patients exhibited persistent spinal instability after an initial procedure. This was caused by erosion of a multistranded cable through the intact arch of C-2 in two cases, by pin site infection necessitating early halo removal in one case, and by slippage in a halo following a Gallie procedure, which was revised with a Brooks fusion in one case. This series, the largest yet published, shows that with appropriate surgical management, posterior upper cervical fusion in the pediatric population is highly successful. Careful attention to halo pin site care and caution in using multistranded cable in young patients may improve results.

Editorial: Pediatric TBI - Current State of the Art and Future Perspective

Elham Rostami, Anthony Figaji, P. David Adelson
2021 Frontiers in Neurology  
Editorial on the Research Topic Pediatric TBI -Current State of the Art and Future Perspective Traumatic Brain Injury (TBI) remains a leading cause of death and disability in children worldwide and those who survive may suffer long-term cognitive and physical disabilities, The mechanism of injury often differs between high income and low-and middle-income countries, where road traffic accidents and interpersonal violence are comparatively more common. In the publication of Riemann et al. using

The overall mortality rate was 3% and the rate of unfavorable outcome 10%, where Glasgow Coma Score (GCS) and the occurrence of secondary insults were identified as independent predictors for an unfavorable outcome. Monitoring the injured brain is crucial in the management of TBI in order to prevent and detect secondary insults. Brain imaging and multimodal neuromonitoring in adults with TBI have improved diagnostics and management of these patients but there is limited experience in the pediatric population. As Appavu et al. describe in their paper methods of monitoring real-time cerebral physiology are also needed in the pediatric population to better understand when secondary brain injury develops and what treatment strategies may alleviate or prevent such injury. They discuss several different emerging technologies to better understand intracranial pressure (ICP), cerebral blood flow, metabolism, oxygenation, and electrical activity. While recent guidelines recommend ICP monitoring and a treatment threshold of 20 mmHg for 5 min, Hornshoj Pedersen et al. highlight the lack of data on normal ICP in healthy children to understand and guide treatment of TBI. Although age-differentiated ICP thresholds in pediatric TBI are needed, only one study reported this and it did not correlate with outcome. The issue with age-differentiated thresholds is also discussed by Rostami et al. regarding CBF. Monitoring of CBF and autoregulation following TBI is crucial. However, there is still lack of fundamental knowledge about normal physiology in children for both across the age spectrum and between genders. Few studies available report on differences across the age range. Following TBI, low initial CBF correlates with poor outcome, as does impaired cerebral pressure autoregulation, but the relationship between the two still needs clarification. Current studies are few and mainly based on small number of patients between the broad age span of 0-18 years. Larger studies across narrower age ranges are needed. The age range affects physiology, mechanism of injury, and outcome. For example, TBI outcome is age dependant: children under the age of 4-5 years have the worse outcome and the rates of TBI-related emergency department visits in this group have increased by more than 50% in US during recent years. Children under the age

Microglia: dismantling and rebuilding circuits after acute neurological injury

Jenna M. Ziebell, P. David Adelson, Jonathan Lifshitz
2014 Metabolic brain disease  
The brain is comprised of neurons and its support system including astrocytes, glial cells and microglia, thereby forming neurovascular units. Neurons require support from glial cells to establish and maintain functional circuits, but microglia are often overlooked. Microglia function as the immune cell of the central nervous system, acting to monitor the microenvironment for changes in signaling, pathogens and injury. More recently, other functional roles for microglia within the healthy brain

This review aims to highlight and discuss these alternate microglial roles in the healthy and in contrast, diseased brain with a focus on two acute neurological diseases, traumatic brain injury and epilepsy. In these conditions, microglial roles in synaptic stripping and stabilization as part of neuronal:glial interactions may position them as mediators of the transition between injury-induced circuit dismantling and subsequent reorganization. Increased understanding of microglia roles could identify therapeutic targets to mitigate the consequences of neurological disease. Keywords Microglia . Synaptic stripping . Neurological disease .

Using anesthetics and analgesics in experimental traumatic brain injury

Rachel K. Rowe, Jordan L. Harrison, Theresa C. Thomas, James R. Pauly, P. David Adelson, Jonathan Lifshitz
2013 Lab animal  
The use of animal modeling in traumatic brain injury (TBI) research is justified by the lack of sufficiently comprehensive in vitro and computer modeling that incorporates all components of the neurovascular unit. Valid animal modeling of TBI requires accurate replication of both the mechanical forces and secondary injury conditions observed in human patients. Regulatory requirements for animal modeling emphasize the administration of appropriate anesthetics and analgesics unless withholding

The objective of this review is to present scientific justification for standardizing the use of anesthetics and analgesics, within a study, when modeling TBI in order to preserve study validity. Evidence for the interference of anesthetics and analgesics in the natural course of brain injury calls for consistent consideration of pain management regimens when conducting TBI research. Anesthetics administered at the time of or shortly after induction of brain injury can alter cognitive, motor, and histological outcomes following TBI. A consistent anesthesia protocol based on experimental objectives within each individual study is imperative when conducting TBI studies to control for the confounding effects of anesthesia on outcome parameters. Experimental studies that replicate the clinical condition are essential to gain further understanding and evaluate possible treatments for TBI. However, with animal models of TBI it is essential that investigators assure a uniform drug delivery protocol that minimizes confounding variables, while minimizing pain and suffering. Additional Considerations Differences in outcome among physically similar individuals following equivalent traumatic brain injuries can be particularly noticeable. Minimizing confounds of analgesic and anesthetic drugs are only one step toward conducting valid and reproducible animal modeling of TBI. Differences in weight, sex, age at injury, and genetic background can influence recovery by altering how individuals sustain the mechanical forces and endure the secondary injury processes of brain injury.
