Abstract
BACKGROUND AND OBJECTIVES To compare the outcomes of early vs no-neurosurgical intervention in civilians with penetrating brain injury (PBI). METHODS We collected data from the National Trauma Data Bank for PBI between 2017 and 2019. A total of 10 607 cases were identified; 1276 cases met the following criteria: age 16-60 years, an intensive care unit (ICU) length of stay (LOS) of >2 days, a Glasgow Coma Scale of 3-12, and at least one reactive pupil on presentation. Patients with withdrawal of life-sustaining treatments within 72 hours were excluded, leaving 1231 patients for analysis. Neurosurgical intervention was defined as an open-approach cranial procedure involving release, drainage, or extirpation of brain matter performed within 24 hours. Outcomes of interest were mortality, withdrawal of life-sustaining treatments, ICU LOS, and dispositional outcome. RESULTS The target population was 1231 patients (84.4% male; median [IQR] age, 29 [18] years); 267 (21.7%) died, and 364 (29.6%) had a neurosurgical intervention within the first 24 hours. 1:1 matching yielded 704 patients (352 in each arm). In the matched cohort (mortality 22.6%), 64 patients who received surgery (18.2%) died compared with 95 (27%) in the nonsurgical group. Survival was more likely in the surgical group (odds ratio [OR] 1.66, CI 1.16-2.38, P < .01; number needed to treat 11). Dispositional outcome was not different. Overlap propensity score-weighted analysis (1231 patients) resulted in higher odds of survival in the surgical group (OR 1.8, CI 1.16-2.80, P < .01). The E-value for the OR calculated from the matched data set was 2.83. Early neurosurgical intervention was associated with longer ICU LOS (median 12 days [7.0, 19.0 IQR] vs 8 days [4.0, 15.0 IQR], P < .05). CONCLUSION Management including early neurosurgical intervention is associated with decreased mortality and increased ICU LOS in matched cohorts of PBI.

Dose-dependent modulation of microglia activation in rats after penetrating traumatic brain injury (pTBI) by transplanted human neural stem cells. PLoS One 2023; 18:e0285633.

Abstract
Traumatic brain injury (TBI) often results in long-lasting patterns of neurological deficits including motor, sensory, and cognitive abnormalities. Cranial gunshot survivors are among the most disabled TBI patients and face a lifetime of disability with no approved strategies to protect or repair the brain after injury. Recent studies using a model of penetrating TBI (pTBI) have reported that human neural stem cells (hNSCs) transplantation can lead to dose and location-dependent neuroprotection. Evidence for regional patterns of microglial activation has also been reported after pTBI with evidence for microglial cell death by pyroptosis. Because of the importance of injury-induced microglial activation in the pathogenesis of TBI, we tested the hypothesis that dose-dependent hNSC mediated neuroprotection after pTBI was associated with reduced microglial activation in pericontusional cortical areas. To test this hypothesis, quantitative microglial/macrophage Iba1 immunohistochemistry and Sholl analysis was conducted to investigate the arborization patterns using four experimental groups including, (i) Sham operated (no injury) + low dose (0.16 million cells/rat), (ii) pTBI + vehicle (no cells), (iii) pTBI + low dose hNSCs (0.16 million/rat), and (iv) pTBI + high dose hNSCs (1.6 million cells/rat). At 3 months post-transplantation (transplants at one week after pTBI), the total number of intersections was significantly reduced in vehicle treated pTBI animals versus sham operated controls indicating increased microglia/macrophage activation. In contrast, hNSC transplantation led to a dose-dependent increase in the number of intersections compared to pTBI vehicle indicating less microglia/macrophage activation. The peak of Sholl intersections at 1 μm from the center of the microglia/macrophages ranged from ~6,500-14,000 intersections for sham operated, ~250-500 intersections for pTBI vehicle, ~550-1,000 intersections for pTBI low dose, and ~2,500-7,500 intersections for pTBI high dose. Plotting data along the rostrocaudal axis also showed that pericontusional cortical areas protected by hNSC transplantation had increased intersections compared to nontreated pTBI animals. These studies using a non-biased Sholl analysis demonstrated a dose-dependent reduction in inflammatory cell activation that may be associated with a neuroprotective effect driven by the cellular transplant in perilesional regions after pTBI.

Abstract
Background The aim of this study was to report the demographics and clinical features of patients with penetrating traumatic brain injury (PTBI) during the past 5 years in Rajaee Hospital, a tertiary referral trauma center in Shiraz, southern Iran. Methods We conducted a 5-year retrospective evaluation of all patients diagnosed with PTBI who were referred to Rajaee Hospital. We retrieved the following items from the hospital's database and PACS system: patients' demographics, on-admission Glasgow Coma Scale (GCS), presence of trauma to other organs, duration of the hospital and ICU stay, the neurosurgical interventions, any necessity of tracheostomy, duration of ventilator dependency, the entrance point of the trauma in the skull, type of assault, length of trajectory in the brain parenchyma, the number of remaining objects in the brain, the occurrence of any hemorrhagic phenomenon, the cross of the bullet from the midline or coronal suture, and the presence of the pneumocephalus. Results A total of 59 patients with a mean age of 28.75 ± 9.40 had PTBI over the 5 years. The mortality rate was 8.5%. Stab wounds, shotguns, gunshots, and airguns were the cause of injury in 33 (56%), 14 (23.7%), 10 (17%), and 2 (3.4%) patients, respectively. The median initial GCS of patients was 15 (3-15). Intracranial hemorrhage was observed in 33 cases, subdural hematoma in 18 cases, intraventricular hemorrhage in eight cases, and subarachnoid hemorrhage in four cases. The mean duration of hospitalization was 10.05 ± 10.75 (ranging from 1 to 62 days). Furthermore, 43 patients experienced ICU admission with mean days of 6.5 ± 5.62 (1-23). The temporal and frontal regions were the most common entrance points, in 23 and 19 patients, respectively. Conclusion The incidence of PTBI is relatively low in our center, possibly due to the prohibition of possession or using warm weapons in Iran. Further, multicenter studies with larger sample sizes are needed to determine prognostic factors associated with worse clinical outcomes after PTBI.

Abstract
BACKGROUND Firearm head injuries cause great public health concern because of their severity. They are life-threatening due to intracranial lesions and sepsis risks. This prospective study evaluates the management of craniocerebral wounds in Chad. METHODS This is an observational study conducted over a period of 65 months with 44 patients with a ballistic craniocerebral wound (BCW), of which only 7.18% were assessed by neurosurgeons with gunshot wound. RESULTS The mean age was 30.57 ± 13 years (range:2-60 years). The 21-30 age group was the most affected (31.8%). The sex ratio was 21. A total of 63.6% of cases involved military personnel. The average admission time was 24.95 ± 12 hours (range: 1-72 hours). Explosive device attacks represented 29.5% of cases, of which 53.3% occurred in civilian practice. Point-blank shooting was reported in 70.5% of cases. The entry hole of the projectile was frontal in 40.9%. Intracranial sequestration of the projectile was found in 56.8%. Association of upper limb trauma was found in 9.1% of cases. Brain scans were performed in 95.5% of cases. Surgical treatment was undertaken in 68.18% of cases. The recovery process was marked by brain abscess in 6.8% of cases. Seven deaths were recorded. CONCLUSIONS This study shows that BCW is frequent and mainly affects young male individuals in Chad. Many of the cases were related to improvised explosive device attacks, especially in civilian practice (70.5%). The delay in diagnostic and therapeutic management favors the high rate of sequelae.

Abstract
Civilian cranial gunshot wounds are common injuries associated with significant morbidity and mortality. Simple wound closure has been previously proposed as an alternative treatment option for a small subset of patients, but the exact outcomes of this strategy are not well-defined. The objective of this paper was to describe the scientific literature reporting simple wound closure of civilian cranial gunshot wounds, its effect on short-term and long-term neurologic outcomes, and rates of seizures and infections. A systematic literature review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The strength of evidence was assessed using the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) criteria. Seventeen studies were found that met inclusion criteria. There was very low strength of evidence that patients treated with simple wound closure can achieve good short and long-term neurologic outcomes. There was very low strength of evidence that simple wound closure has a higher incidence of mortality compared to operative intervention, especially in patients with initial low Glasgow Coma Scale (GCS) scores. There was very low strength of evidence that patients treated with simple wound closure have a small risk of subsequently developing infections or seizures. In conclusion, under most circumstances, neurosurgical operative intervention should be viewed as the optimal treatment for salvageable civilian cranial gunshot wound patients. However, our literature review showed that simple wound closure is safe and viable. More data are needed to determine the appropriate clinical scenario for using this alternative option.

Abstract
BACKGROUND We aimed to determine the outcomes and prognostic factors in pediatric craniocerebral gunshot injury (CGI) patients. Pediatric patients may have significantly different physiology, neuroplasticity, and clinical outcomes in CGI than adults. There is limited literature on this topic, mainly case reports and small case series. METHODS We queried the National Trauma Data Bank for all pediatric CGI between 2014 and 2017. Patients were identified using International Classification of Diseases, Ninth Revision, codes. Demographic, emergency department, and clinical data were analyzed. Subgroup analysis was attempted for groups with Glasgow Coma Scale (GCS) scores of 9 to 15 and ages 0 to 8 years. RESULTS In a 3-year period, there were 209 pediatric patients (aged 0-18 years) presenting to American hospitals with signs of life. The overall mortality rate was 53.11%. A linear relationship was demonstrated showing a mortality rate of 79% by initial GCS in GCS score of 3, 56% in GCS scores of 4 to 8, 22% in GCS scores of 9 to 12, and 5% in GCS scores of 13 to 15. The youngest patients, aged 0 to 8 years, had dramatically better initial GCS and subsequently lower mortality rates. Regression analysis showed mortality benefit in the total population for intracranial pressure monitoring (odds ratio, 0.267) and craniotomy (odds ratio, 0.232). CONCLUSION This study uses the National Trauma Data Bank to quantify the prevalence of pediatric intracranial gunshot wounds, with the goal to determine risk factors for prognosis in this patient population. Significant effects on mortality for invasive interventions including intracranial pressure monitoring and craniotomy for all patients suggest low threshold for use of these procedures if there is any clinical concern. The presence of a 79% mortality rate in patients with GCS score of 3 on presentation suggests that as long as there is not a declared neurologic death, intracranial pressure monitoring and treatment measures including craniotomy should be considered by the consulting clinician. LEVEL OF EVIDENCE Prognostic and epidemiological, level III.

Abstract
This article aims to evaluate the predictive factors of morbidity and mortality in pediatric patients who suffered gunshot wounds to the head. We reviewed a series of 43 patients who were admitted to a referential neurosurgical hospital between 2010 and 2019. Data from 43 patients who underwent a surgical treatment in our institution were collected, and the following parameters were considered in the analysis: the initial Glasgow Coma Scale (GCS), age, sex, bullet entry site, and bullet trajectory. Computed tomography (CT) scans at admission, complications, midline crossing, and Glasgow score scale at the time of discharge (Glasgow Outcome Scale; GOS) were also factored in. Male sex corresponded to 90.7% of cases (N = 39), and 16–17 years of age was the most common age (60.5%). The frontal region was the most common entry site (41.9%), followed by the parietal wall and occipital entry. Penetrating trajectory was shown in 48.8% of cases, perforation/transfixing in 39.5%, and tangential in 11.6%. CT showed that sinking is the most common alteration (74.4%), followed by cerebral contusion (44.2%). According to the GOS, 23.3% died, 23.3% were classified by an unfavorable outcome (GOS, 2–3), and 53.5% a favorable outcome (GOS, 4 and 5). In our study, there was a significant association between the low GCS scores on admission and low GOS (1–3; p = 0.001) at time of discharge. Patients with wounds that crossed the midline also had a significant association with low GOS (p = 0.014) in our clinical experience. We concluded that low GCS scores at admission and children with a wound that crosses the midline are predictive factors of high mortality and morbidity, in our clinical experience.

Abstract
INTRODUCTION Penetrating craniocerebral injuries (PCCI) are types of open head injuries caused by sharp objects or missiles, resulting in communication between the cranial cavity and the external environment. This condition is deemed to be more prevalent in armed conflict regions where both civilians and military are frequently assaulted on the head, but paradoxically their hospital outcomes are under-reported. We aimed to identify factors associated with poor hospital outcomes of patients with PCCI. METHODS This was a retrospective series of patients admitted at the Regional Hospital of Bukavu, DRC, from 2010 to 2020. We retrieved medical records of patients with PCCI operated in the surgical departments. A multivariate logistic regression model was performed to find associations between patients' admission clinico-radiological parameters and hospital outcomes. Poor outcome was defined as a Glasgow Outcomes Score below 4. RESULTS The prevalence of PCCI was 9.1% (91/858 cases) among admitted TBI patients. More than one-third (36.2%) of patients were admitted with GCS < 13, and 40.6% of them were unstable hemodynamic. Hemiplegia was found in 23.1% on admission. Eight patients had an intracerebral hemorrhage. Among the 69 operated patients, complications, mainly infectious, occurred in half (50.7%) of patients. Poor hospital outcomes were observed in 30.4% and associated with an admission GCS < 13, hemodynamic instability, intracerebral hemorrhage, and hemiplegia (p < 0.05). CONCLUSION The hospital poor outcomes are observed when patients present with hemodynamic instability, an admission GCS < 13, intracerebral hemorrhage, and hemiplegia. There is a need for optimizing the initial care of patients with PCCI in armed conflict regions.

Traumatic Cerebrovascular Injuries Associated with Gunshot Wounds to the Head: A Single-Institution Ten-Year Experience. World Neurosurg 2020; 146:e1031-e1044. [PMID: 33227526 DOI: 10.1016/j.wneu.2020.11.078] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 11/11/2020] [Accepted: 11/12/2020] [Indexed: 12/27/2022]
Abstract
BACKGROUND Cerebrovascular injury (CVI) is a potentially devastating complication of gunshot wounds to the head (GSWH), with yet unclear incidence and prognostic implications. Few studies have also attempted to define CVI risk factors and their role in patient outcomes. We aimed to describe 10 years of CVI from GSWH and characterize these injury patterns. METHODS Single-institution data from 2009 to 2019 were queried to identify patients presenting with dural-penetrating GSWH. Patient records were reviewed for GSWH characteristics, CVI patterns, management, and follow-up. RESULTS Overall, 63 of 297 patients with GSWH underwent computed tomography angiography (CTA) with 44.4% showing CVI. The middle cerebral artery (22.2%), dural venous sinuses (15.9%), and internal carotid artery (14.3%) were most frequently injured. Arterial occlusion was the most prominent injury type (22.2%) followed by sinus thrombosis (15.9%). One fifth of patients underwent delayed repeat CTA, with 20.1% showing new/previously unrecognized CVI. Bihemispheric bullet tracts were associated with CVI occurrence (P = 0.001) and mortality (P = 0.034). Dissection injuries (P = 0.013), injuries to the vertebrobasilar system (P = 0.036), or the presence of ≥2 concurrent CVIs (P = 0.024) were associated with increased risk of mortality. Of patients with CVI on initial CTA, 30% died within the first 24 hours. CONCLUSIONS CVI was found in 44.4% of patients who underwent CTA. Dissection and vertebrobasilar injuries are associated with the highest mortality. CTA should be considered in any potentially survivable GSWH. Longitudinal study with consistent CTA use is necessary to determine the true prevalence of CVI and optimize the use of imaging modalities.

Abstract
OBJECTIVE Penetrating brain injury (PBI) is the most lethal of all firearm injuries, with reported survival rates of less than 20%. The projectile trajectory (PT) has been shown to impact mortality, but the significant lobar tracks have not been defined. The aim of this retrospective case-control study was to test for associations between distinct ballistic trajectories, missile types, and patient outcomes. METHODS A total of 243 patients who presented with a PBI to the Saint Louis University emergency department from 2008 through 2019 were identified from the hospital registry. Conventional CT scans combined with 3D CT reconstructions and medical records were reviewed for each patient to identify distinct PTs. RESULTS A total of 65 ballistic lobar trajectories were identified. Multivariable regression models were used, and the results were compared with those in the literature. Penetrating and perforating types of PBI associated with bitemporal (t-statistic = -2.283, p = 0.023) or frontal-to-contralateral parietal (t-statistic = -2.311, p = 0.025) projectile paths were universally found to be fatal. In the group in which the Glasgow Coma Scale (GCS) score at presentation was lower than 8, a favorable penetrating missile trajectory was one that involved a single frontal lobe (adjusted OR 0.02 [95% CI 0.00-0.38], p = 0.022) or parietal lobe (adjusted OR 0.15 [95% CI 0.02-0.97], p = 0.048). Expanding or fragmenting types of projectiles carry higher mortality rates (OR 2.53 [95% CI 1.32-4.83], p < 0.001) than do nondeformable missiles. Patient age was not associated with worse outcomes when controlled by other significant predictive factors. CONCLUSIONS Patients with penetrating or perforating types of PBI associated with bitemporal or frontal-to-contralateral parietal PTs should be considered as potential donor candidates. Trauma patients with penetrating missile trajectories involving a single frontal or parietal lobe should be considered for early neurosurgical intervention, especially in the circumstances of a low GCS score (< 8). Surgeons should not base their decision-making solely on advanced patient age to defer further treatment. Patients with PBIs caused by nondeformable types of projectiles can survive multiple simultaneous intracranial missile trajectories.

Abstract
BACKGROUND Pediatric craniocerebral gunshot injuries (CGIs) occur both in the context of accidental and intentional trauma. The incidence and physiology of pediatric CGIs merit reexamination of prognostic factors and treatment priorities. This study characterizes the current understanding of mortality and prognostic factors in this patient population. METHODS A systematic search was conducted. Selection criteria included all studies published since 2000, which described civilian isolated CGIs in pediatric patients. Data were analyzed qualitatively and quantitatively to identify factors prognostic for the primary outcome of mortality. Secondary outcomes included functional outcome status, requirement for surgery, and injury complications. Study quality was assessed with the Newcastle-Ottawa Scale. This study was registered with PROSPERO (CRD42019134231). RESULTS Initial search revealed 349 unique studies. Forty underwent full text screening, and eight studies were included in the final synthesis. The overall mortality rate was 44.8%. Most CGIs occurred in older teenagers. Aggressive surgical treatment was recommended by one author, while remaining studies emphasized clinical judgment. Reported prognostic factors include initial Glasgow Coma Scale, pupil reactivity, involvement of multiple lobes or deep nuclei, and bihemispheric injuries. Reported complications from CGIs included seizure, meningitis, abscess, cerebrospinal fluid leak, bullet migration, focal neurological deficits, endocrine abnormalities, cognitive deficits, and neuropsychological deficits. The Glasgow Outcome Scale was the predominant measure of function and demonstrated a moderate recovery in 17.4% and a good recovery in 27.3% of patients. CONCLUSION This systematic review analyzed the existing evidence for prognostic factors in the context of pediatric CGIs. Significant long-term clinical improvement is possible with interventions including urgent surgical therapy. Fixed bilateral pupils and low initial Glasgow Coma Scale correlate with mortality but do not predict all patient outcomes. Patients younger than 15 years are underreported and may have differences in outcome. The literature on pediatric CGIs is limited and requires further characterization. LEVEL OF EVIDENCE Systematic Review, level IV.
