Traumatic brain injury can lead to locally destructive secondary events mediated by several inflammatory components. Following lateral fluid-percussion (FP) brain injury in rats, we examined cortical and hippocampal sections for neutrophil infiltration and accumulation of complement component C3. Neutrophil influx into the brain after injury was detected by an improved myeloperoxidase (MPO) microassay and manual cell counting, while C3 accumulation was detected using immunocytochemistry. MPO levels were elevated in the injured cortical tissue, whereas C3 immunoreactivity was increased in both injured cortical and ipsilateral hippocampal sections. These results show that the FP model of head injury leads to an intense local inflammatory reaction and subsequent tissue destruction.

Iatrogenic pseudoaneurysm formation of the anterior cerebral artery following placement of an external ventricular drain: illustrative case.
J Neurosurg Case Lessons
January 2025
Department of Neurological Surgery, Cooper University Health Care, Camden, New Jersey.
Background: External ventricular drains (EVDs) provide an invaluable diagnostic method for accessing cerebrospinal fluid and therapeutically treating elevated intracranial pressure. Although complications including hemorrhage and infection have been well documented, the formation of iatrogenic pseudoaneurysms following EVD placement has rarely been reported. The authors present a case of this exceedingly rare complication of iatrogenic pseudoaneurysm formation following EVD placement.

Chitinase 3-like protein 1 (CHI3L1) is emerging as a promising biomarker for assessing intracranial lesion burden and predicting prognosis in traumatic brain injury (TBI) patients. Following experimental TBI, Chi3l1 transcripts were detected in reactive astrocytes located within the pericontusional cortex. However, the cellular sources of CHI3L1 in response to hemorrhagic contusions in human brain remain unidentified.

Background: Some studies suggest that balanced solutions may improve outcomes in critical care patients. However, in patients with traumatic brain injury (TBI) existing data indicate that normal saline may be preferred. We hypothesized that mortality in critically ill patients with and without TBI would differ with the use of balanced salt solutions versus normal saline.

Experiences of loss and change following acquired brain injury (ABI) are frequent and multi-contextual, yet the long-term experiences of people with ABI are not well understood. This study explored the experiences of intrapersonal loss, grief and change in people with ABI, a decade after their injury. Twelve adults with ABI were interviewed 10-13 years post-injury.

The diagnosis of abusive head trauma (AbHT) in children is a challenging one that needs to be differentiated from natural disease and accidental head injury (AcHT). There is increasing evidence from the Neuroradiology field showing spinal cord injury in children subject to AbHT, which has, so far, been poorly investigated pathologically. In this study we retrospectively reviewed the forensic records of 110 paediatric head injury cases over an eight-year-period.
