Papillary glioneuronal tumor (PGNT) is a recently described central nervous system neoplasm. In 2007, the World Health Organization classified this tumor as a grade I neuronal-glial neoplasm. Patients are usually juvenile and young adults who commonly present with headache or seizures. We report a case of a 13-year-old boy that was related to our hospital after suffering a mild head injury result of an automobile accident. Emergent CT scan showed a right hypointense temporo-occipital lesion. MRI confirmed the presence of a lesion suggestive of a primary brain tumor...

BACKGROUND: Mild traumatic brain injury (mTBI) comprises the majority of pediatric traumatic brain injury. Children with mTBI even with traumatic intracranial hemorrhage (tICH) rarely experience a clinically significant neurologic decline (CSND). The utility of routine surveillance imaging in the pediatric population also remains controversial, especially owing to concerns about the risks of radiation exposure at a young age. This study aims to identify demographic or injury-related characteristics that may facilitate recognition of children at risk of progression with mTBI...

BACKGROUND: Radiocapitellar pathology after traumatic injury to the elbow can be challenging to treat. The anconeus interposition arthroplasty has been proposed to treat radiocapitellar or proximal radioulnar joint dysfunction and pain, or both. This study evaluated whether radial head excision (native or prosthetic), followed by an anconeus interposition arthroplasty, relieves pain and improves subjective and objective elbow function in patients with post-traumatic radiocapitellar pathology...

We report a case involving the development of a delayed acute subdural hematoma (ASDH) after trauma, with the absence of any abnormal radiological and clinical findings at initial examination. A 54-year-old male visited the emergency department after a minor trauma. The patient only complained of mild headache after head injury. He presented no abnormal findings on neurological examination, and brain computed tomography (CT) did not show any intracranial lesion or skull fractures. However, he developed seizure with disorientation eight hours after trauma, and ASDH with midline shift was found during a follow-up CT...

Background Post-traumatic headache is the most common and long-lasting impairment observed following mild traumatic brain injury, and frequently has migraine-like characteristics. The mechanisms underlying progression from mild traumatic brain injury to post-traumatic headache are not fully understood. The aim of this study was to develop a mouse model of post-traumatic headache and identify mechanisms and novel targets associated with this disorder. Methods We combined the closed head weight-drop method and the nitroglycerin chronic migraine model...

Traumatic brain injury is a major source of global disability and mortality. Preclinical TBI models are a crucial component of therapeutic investigation. We report a tunable, monitored model of murine non-surgical, diffuse closed-head injury-modCHIMERA-characterized by impact as well as linear and rotational acceleration. modCHIMERA is based on the Closed-Head Impact Model of Engineered Rotational Acceleration (CHIMERA) platform. We tested this model at 2 energy levels: 1.7 and 2.1 Joules-substantially higher than previously reported for this system...

INTRODUCTION: The American College of Emergency Physicians embarked on the "Choosing Wisely" campaign to avoid computed tomographic (CT) scans in patients with minor head injury who are at low risk based on validated decision rules. We hypothesized that a Pediatric Mild Head Injury Care Path could be developed and implemented to reduce inappropriate CT utilization with support of a clinical decision support tool (CDST) and a structured parent discussion tool. METHODS: A quality improvement project was initiated for 9 weeks to reduce inappropriate CT utilization through 5 interventions: (1) engagement of leadership, (2) provider education, (3) incorporation of a parent discussion tool to guide discussion during the emergency department (ED) visit between the parent and the provider, (4) CDST embedded in the electronic medical record, and (5) importation of data into the note to drive compliance...

Background: Routine repeat cranial CT (RHCT) is standard of care for CT-verified traumatic brain injury (TBI). Despite mixed evidence, those with mild TBI are subject to radiation and expense from serial CT scans. Thus, we investigated the necessity and utility of RHCT for patients with mild TBI. We hypothesized that repeat head CT in these patients would not alter patient care or outcomes. Methods: We retrospectively studied patients suffering from mild TBI (Glasgow Coma Scale (GCS) score 13-15) and treated at the R Adams Cowley Shock Trauma Center from November 2014 through January 2015...

BACKGROUND: The neurosurgical literature rarely describes managing open head injuries caused by machetes, although this is a common head injury in developing countries. We present our experience managing cranial machete injuries in Nicaragua over a 5-year period. METHODS: A retrospective chart review identified patients admitted to a neurosurgery service for cranial machete injury. RESULTS: Among 51 patients studied, the majority (n=42, 82%) presented with mild neurological deficits (Glasgow Coma Scale score ≥14)...

Emerging data suggest that pediatric traumatic brain injury (TBI) is associated with impaired developmental plasticity and poorer neuropsychological outcomes than adults with similar head injuries. Unlike adult mild TBI (mTBI), the effects of mTBI on white matter (WM) microstructure and vascular supply are not well-understood in the pediatric population. The cerebral vasculature plays an important role providing necessary nutrients and removing waste. To address this critical element, we examined the microstructure of the corpus callosum (CC) following pediatric mTBI using diffusion tensor imaging (DTI), and investigated myelin, oligodendrocytes, and vasculature of WM with immunohistochemistry...

Repeated concussion is becoming increasingly recognized as a serious public health concern around the world. Moreover, there is a greater awareness amongst health professionals of the potential for repeated pediatric concussions to detrimentally alter the structure and function of the developing brain. To better study this issue, we developed an awake closed head injury (ACHI) model that enabled repeated concussions to be performed reliably and reproducibly in juvenile rats. A neurological assessment protocol (NAP) score was generated immediately after each ACHI to help quantify the cumulative effects of repeated injury on level of consciousness, and basic motor and reflexive capacity...

Traumatic brain injury (TBI) has long been identified as a precipitating risk factor for higher order cognitive deficits associated with the frontal and prefrontal cortices (PFC). In addition, mild repetitive TBI (rTBI), in particular, is being steadily recognized to increase the risk of neurodegenerative disease. Thus, further understanding of how mild rTBI changes the pathophysiology of the brain to lead to cognitive impairment is warranted. The current models of rTBI lack knowledge regarding chronic higher order cognitive functions and the underlying neuronal physiology, especially functions involving the PFC...

Plasma tau and glial fibrillary acidic protein (GFAP) are promising biomarkers for identifying traumatic brain injury (TBI) patients with intracranial trauma on CT. Accuracy in older adults with mild TBI (mTBI), the fastest growing TBI population, is unknown. Our aim was to assess for age-related differences in diagnostic accuracy of plasma tau and GFAP for identifying intracranial trauma on CT. Samples from 169 patients (age <40y [n=79], age 40-59y [n=60], age 60y+ [n=30]), a subset of patients from the TRACK-TBI Pilot study, who presented with mTBI (GCS 13-15), received head CT, and consented to blood-draw within 24h of injury were assayed for hyperphosphorylated-tau (P-tau), total-tau (T-tau; both via amplification-linked enhanced immunoassay using multi-arrayed fiberoptics), and GFAP (via sandwich enzyme-linked immunosorbent assay)...

REVIEW
Stoyan Popkirov, Alan J Carson, Jon Stone
A history of head injury is common in patients with psychogenic nonepileptic seizures (PNES). This association has so far been interpreted as either spurious or psychologically mediated. Biased recall and misattribution could foster illness beliefs about brain damage that promote symptom production. Furthermore, the emotional impact of head injury could induce long-term changes in stress responsivity. Lastly, maladaptive cognitive-behavioural processes involving symptom modelling and aversive conditioning, known to play a role in functional neurological disorders, could contribute to the development of PNES after head trauma...
