Objective : Civilian gunshot injuries to the brain are relatively rare and study of these injuries has been neglected in South Korea. We present our experience with penetrating gunshot injuries to the brain and review the outcome of surgical management, as well as other clinical predictors influencing the prognosis. Methods : We present a retrospective analysis of 13 patients with penetrating gunshot injuries to the brain who were treated at our hospital over a period of 22 years. Results : The Glasgow Coma Scale[GCS] score on admission was recorded to be : 3-5 in 1 patient, 6-8 in 3 patients, 9-12 in 2 patients and 13-15 in 7 patients. There were 11 patients who underwent surgical treatment, and the surgical mortality rate was 0%. The admission GCS score was the most valuable prognostic factor. The best results were found to be in patients admitted with an initial GCS higher than 13. There were no favorable outcomes in patients admitted with a GCS of 8 or lower. There was a correlation between the presence of a transventricular or bihemispheric trajectory and poor outcome. The patients admitted with unilobar wounds resulted in better outcome than those with bilobar or multilobar wounds. Retained deep intracranial bone or metal fragments were the most common postoperative complication. However, retained fragments did not increase the risk of infection or seizure. Conclusion : Our results suggest that a less aggressive approach, consisting of minimal local debridement and removal of the bone and metal fragments that are easily accessible, can be successfully used in civilian gunshot wounds to the brain.
Objective : The purpose of this study was to investigate the factors affecting the surgical outcome and to compare the surgical results between transsylvian and transcortical approaches in patients with putaminal hematomas. Methods : Retrospective review of charts and CT scan images was conducted in 45 patients (20 transsylvian and 25 transcortical approaches) who underwent open surgical evacuation of putaminal hematomas. Mean Glasgow coma scale (GCS) score and hematoma volume were $7.5{\pm}3.2$ and $78.1{\pm}29.3\;cc$, respectively. The factors affecting the functional mortality were investigated using a multivariate logistic regression analysis. In addition, surgical results between transsylvian and transcortical approaches were compared. Results : None of the patients had a good recovery after the surgery. Overall functional survival rate and mortality were 37.7% and 31%, respectively. The only risk factor for functional mortality was GCS motor score after controlling age, history of hypertension, side of hematoma, hematoma amount midline shift, presence of intraventricular hemorrhage and surgical approach (p=0.005). Even though a transcortical approach was shorter in operative time (4.4 versus 5.1 hour) and showed a higher mortality rate (40% versus 20%) and lower functional survival (45% versus 35%) compared to the transsylvian approach, the differences were not statistically significant between the two groups. Conclusion : In patients who have large amounts of hematoma and require open surgical evacuation, the only significant risk factor for functional survival is the preoperative GCS score. Cortical incision methods such as transsylvian and transcortical approaches have no influence on the surgical outcome. To decompress the swollen brain rapidly, transcortical approach seems to be more suitable than transsylvian approach.
Objective: This study was performed to evaluate the usefulness of early operation in children with traumatic subdural hygroma. Methods: The subjects were nine patients (Glasgow coma scale (GCS) score was below 10 and age was below 10 years old) who developed subdural hygroma after trauma between January 2000 to December 2002. Subduroperitoneal shunt was performed in one group and not performed in the other group. We analyzed the GCS score on admission and at 1 year after operation. Overall clinical results were evaluated retrospectively. Results: Patients who underwent operation exhibited higher GCS scores at 1 year after trauma compared to those in the patients who were treated by conservative therapy(p<0.05). Conclusion: The early operation could be an effective treatment to children with subdural hygroma who showed delayed improvement of consciousness and to patients with hygroma that didn't decrease or was above moderate amount.

Purpose: The objective of this study was to develop a new scoring tool that is comprehensively applicable and predicts fatality within 24 h of intoxication. Methods: This was a cohort study conducted in two emergency medical centers from 2011 to 2012. We identified factors associated with severe/fatality. Through a discriminant analysis, we devised the aBIG (age, Base deficit, Infection, and Glasgow coma scale) score. To compare the ability of aBIG to predict intoxication severity with that of previous scoring systems such as APACHE II, MODS, SAPS IIe, and SOFA, we determined the receiver operating characteristic curves of each variable in predicting severe-to-fatal toxicity. Results: Compared with the mild/moderate toxicity group (n=211), the severe/fatal group (n=143) had higher incidences of metabolic acidosis, infection, serious mental change, QTc prolongation and hepato-renal failure. Age, base deficit, infection-WBC count, and Glasgow Coma Scale were independently associated with severe/fatal poisoning. These variables were combined into the poisoning "aBIG" score [$0.28{\times}$Age group+$0.38{\times}WBC$ count/$10^3+0.52{\times}$Base deficit+$0.64{\times}$(15-GCS)], which were each calculated to have an area under the curve of 0.904 (95% confidence interval: 0.868-0.933). The aBIG poisoning score had an equivalent level of severity predictability as APACHE II and a superior than MODS, SOFA, and SAPS IIe. Conclusion: We developed a simplified scoring system using the four variables of age, base deficit, infected leukocytosis, and GCS. The poisoning aBIG score was a simple method that could be performed rapidly on admission to evaluate severity of illness and predict fatal severity in patients with acute intoxications.
Purpose: Assessment of the trauma severity associated with the prognosis of trauma patients. But we are having a lot of difficulties in assess the severity because of scarcity of current first-aid records resources. Methods: We presumed that Applying the Revised trauma score which consist of vital signs and GCS score will be helpful to assess the sevirity.This study covers the 10069 patient of Ewah womans hospital (2011.1.1.-2014.12.31) who are able to verify the GCS score from fist-aid records. Results: There is no distinctions between prehospital RTS and hospital RTS. And shows high level of correlation between prehospital RTS and ISS. Conclusion: Therefore we conclude that checking the GCS and RTS at prehospital state will be help to assess the severity of trauma patients.

Objective : Homeless patients probably have epidemiologic features that are different from those of general population. However, there have been no published articles about clinical characteristics of neurosurgical homeless patients. The authors tried to assess the clinical characteristics and treatment outcome of homeless neurosurgical patients. Methods : We retrospectively reviewed the medical records and radiological films of 76 homeless patients and 72 non-homeless patients following head trauma who were admitted to our neurosurgical department between June 2001 and June 2005. We compared two groups of the patients with the demographics, the clinical and laboratory characteristics. Also, 3D-day mortality was determined according to Glasgow Coma Scale (GCS) score. Results : Age of homeless patients was younger than that of non-homeless patients. Homeless patients had previous craniotomy evidences in skull x-rays more frequently (10.5% vs. 1.4%). Acute subdural hematoma was the most common type of head injury in the two groups. Moderate and severe head injury, based on GCS score on admission was more frequent in homeless patients (64% vs. 39%). Fifty percent of homeless patients underwent operation for traumatic head injury. However, 3D-day mortality according to GCS score was not significantly higher in homeless patients. Conclusion : Most homeless neurological patients were relatively young men. Also, moderate or severe brain injuries were observed more frequently. However, mortality rate of homeless patients in neurosurgical field is not significantly higher in the present study.
We report on changes in the ascending reticular activating system (ARAS) concurrent with the recovery of impaired consciousness following rehabilitation and cranioplasty in a patient with traumatic brain injury (TBI), which were demonstrated on diffusion tensor tractography (DTT). A 34-year-old male patient was diagnosed with a traumatic intracerebral hemorrhage after falling from a height of approximately 7 m and underwent a right frontoparietotemporal decompressive craniectomy and hematoma removal. At 5 months after onset, when starting rehabilitation, the patient showed impaired consciousness, with a Glasgow Coma Scale (GCS) score of 4. Comprehensive rehabilitative therapy was provided until 14 months after onset, and his GCS score improved to 8. Cranioplasty was performed using auto-bone at 14 months after onset. One month after cranioplasty, his GCS score improved to 12. On the 15-month DTT, the deviated lower dorsal ARAS was restored on both sides, and the right side had become thicker. The right lower ventral ARAS was reconstructed, and increased neural connectivity of the upper ARAS was detected in both the prefrontal cortices. Thus, changes in the ARAS were demonstrated in a patient with TBI during recovery of consciousness following rehabilitation and cranioplasty.

Purpose: Incidents of suicide attempt and acute poisoning in the elderly population is rising. This study investigated the clinical nature of acute poisoning and differences between the survival and mortality groups in the elderly. Methods: We retrospectively investigated 325 patients with acute poisoning who visited the emergency department. Patients were divided into two groups, one survival and one death group. Information regarding patient sex, age, root cause of poisoning, time of year of poisoning, type of intoxicant, duration of time between intoxicant ingestion and arrival at the emergency department, total length of hospital stay, and any previous suicide attempts and subsequent hospitalization were collected. An initial Glasgow Coma Scale (GCS) and an initial and final Poison Severity Score (PSS) for each patient was calculated. Results: The survival rate for men was higher than for women in this study. The most common reason of drug intoxication was suicide, with accidental ingestion and substance abuse occurring in descending frequency. Seasonal factors were reflected in the data with the highest number of incidents occurring in spring and the lowest number in winter. Compared with the mortality group, the survival group had a lower initial PSS with a higher GCS. Conclusion: We conclude that being female, having suicide as a root cause, agrochemicals as an intoxicant, low initial Glasgow Coma Scale and high initial Poisoning Severity Score, are all associated with poor prognosis.
Purpose: Diffuse axonal injury (DAI) is clinically defined as a coma of over six hours in a head trauma victim without a focal mass lesion. The emergency physician usually resuscitates and stabilizes a comatose head trauma victim in the emergency Department. After assessment and treatment, the prognosis is very important to both the victim and the physician. The prognosis for DAI is based on Glasgow Coma Scale (GCS) and other imaging data. We investigated the prognostic value of computed tomography (CT) and gradient-echo magnetic resonance imaging (GRI) for head trauma victims with DAI. Methods: Fifty-three(53) head trauma victims of DAI were enrolled in this study from 2007 to 2012. During the study period of six years, data on trauma victims were collected retrospectively. We analyzed the differences in the Glasgow Outcome Scale (GOS) result between the CT and the GRI modalities. Results: We classified the study group by using GOS. Between the good outcome subgroup (GOS scores of 4 and 5) and the poor outcome subgroup (GOS score of 1-3), there were no statistical difference in sex, age, initial vital signs and initial GCS score. The good outcome subgroup had non-hemorrhage on CT(52%), which was correlated with good outcome and a shorter awakening time, while a larger number and a deeper location of hemorrhagic lesions on in GRI were correlated with poor outcome in DAI. Conclusion: We conclude that the existence of hemorrhagic lesions on CT, and the number and location of those lesions on GRI had good prognostic value for head trauma victims with DAI.

Purpose: The Glasgow Coma Scale (GCS), though it is widely used for triage, has been criticized as being unnecessarily complex. Recently, a 3-point Simplified Motor Score (SMS, defined as obeys commands=2; localizes pain=1; withdrawals to pain or worse=0) was developed from the motor component of the GCS and was found to have a similar test performance for triage after traumatic brain injury when compared with the GCS as the criterion standard. The purpose of this study was to validate the SMS. Methods: We analyzed the patients who visited Kyungpook National University Hospital emergency center after traumatic brain injury from 2006 January to 2006 June. The test performance of the GCS, its motor component, and SMS relative to three clinically relevant traumatic brain injury outcomes (abnormal brain CT scans, Abbreviated Injury Scale $(AIS){\geq}4$, and mortality) were evaluated with areas under the receiver operating characteristic curves (AUCs). Results: Of 504 patients included in the analysis, 25.6% had an abnormal brain CT scans, 13.1% had $AIS{\geq}4$, and 5.0% died. The AUCs for the GCS, its motor component, and SMS with respect to the abnormal CT scans were 0.776, 0.715, and 0.716, and respectively, those for $AIS{\geq}4$ and mortality, were 0.969, 0.973, and 0.968, and 0.931, 0.909, and 0.909, respectively. Conclusion: The 3-point SMS demonstrated similar test performance when compared with the 15-point GCS score and its motor component for triage after traumatic brain injury in our populations.
