ABSTRACT
Objective: Whether or not emergent decompression/fusion surgery for paralysis caused by metastatic spinal tumors of unknown origin improves patient neurological outcome and survival remains unclear. This study aimed to evaluate the clinical outcomes of emergent decompression/fusion surgery for paralysis caused by spinal tumors of unknown or not previously diagnosed origin.Patients and Methods: Data from the medical records of 11 patients with spinal tumors of unknown origin (study group) were compared with those of 15 patients with metastatic spinal tumors of known origin (control group). The outcome measures were postoperative performance status, motor function evaluated with the Frankel grade, and actual survival after surgery as compared with the estimated survival calculated using the Tokuhashi score. χ2 analyses were performed to evaluate differences between the groups.Results: The mean performance status was 3.6 preoperatively, which improved to 2.9 postoperatively (P<0.05), in the unknown origin group and 3.6 preoperatively, which improved to 2.7 postoperatively (P<0.05), in the control group. Seven patients (64%) in the unknown origin group showed improvement in paralysis by ≥1 Frankel grade. By contrast, only 4 patients (27%) in the control group showed improvement in paralysis. The unknown origin group tended to show better improvement (P=0.05). All the patients in the unknown origin group underwent adjuvant therapy after definitive diagnosis following surgery. The unknown origin group showed a slight tendency toward better survival than toward the estimated survival.Conclusion: Emergent decompression/fusion surgery for patients with paralysis caused by metastatic tumors of unknown origin is potentially useful for diagnosing tumor origin and improving neurological outcomes and performance status, and thus for extending survival.
ABSTRACT
With the popularization of cardiopulmonary resuscitation (CPR) technology, the success rate of restoration of spontaneous circulation (ROSC) is gradually improved, and the survival rate and neurological outcome of patients with cardiac arrest are improved. Currently, therapeutic methods for cerebral resuscitation after cardiac arrest are limited. In addition to mild hypothermia for clinical application, the majority of drugs remain in the animal experimental stage. Finding effective brain protection drugs has become a hot spot in the field of brain resuscitation research. This article will review the pharmaceutical progress of research for cerebral resuscitation after cardiac arrest, so that we can study the brain protection mechanism of these drugs better and more targeted.
ABSTRACT
OBJECTIVE： To evaluate the efficacy and safety of progesterone in the treatment of acute traumatic brain injury systematically， and to provide reference for clinical use. METHODS： Retrieved from Cochrane library， ClinicalTrials， Web of Science， PubMed， Embase， CBM， CNKI and Wanfang database， randomized controlled trial （RCTs） about progesterone （trial group） versus placebo or blank control （control group） in the treatment of acute traumatic brain injury were collected. After literature screening， data extraction and quality evaluation by risk bias evalution tool of Cochrane systematic evaluator manual 5.1.0， Meta-analysis was performed by using Rev Man 5.3 statistical software. RESULTS： A total of 10 RCTs were included， involving 2 652 patients. Results of Meta-analysis showed that there was no statistical significance in mortality[RR＝0.77，95％CI（0.56，1.07），P＝0.12]， the incidence of septicemia [RR＝1.11，95％CI（0.77，1.60），P＝0.59] or elevated liver enzymes[RR＝1.30，95％CI（0.68，2.50），P＝0.43]. The number of patients with favorable neurological outcome[RR＝1.23，95％CI（1.05，1.43），P＝0.008] in trial group was significantly more than control group. Results of subgroup analysis of mortality showed that there was no statistical significance in the mortality of patient’s GCS≤8 [RR＝0.79，95％CI（0.57，1.10），P＝0.16]， that of patient’s GCS≤12[RR＝0.69，95％CI（0.23，2.10），P＝0.52] or that of patient’s GCS ranging from 9 to 12 [RR＝0.78，95％CI（0.26，2.35），P＝0.65] between 2 groups. Results of subgroup analysis of neurological outcome showed that there was no statistical significance in the number of favorable neurological outcome of patient’s GCS≤8 [RR＝1.18， 95％CI（0.98，1.43），P＝0.09]， the number of favorable outcome of patient’s GCS≤12[RR＝1.15，95％CI（0.87，1.51），P＝0.32] and the number of favorable neurological outcome of patient’s GCS ranging from 9 to 12[RR＝2.07，95％CI（0.24，17.71），P＝0.51]. CONCLUSIONS： Progesterone can improve the prognosis of neurological function in patients with acute traumatic brain injury with good safety but cannot reduce mortality.
ABSTRACT
Objective The level of lactic acid in blood can reflect the degree of ischemia and hypoxia of brain tissue and cerebral perfusion pressure. The aim of this paper is to explore the value of blood lactate and lactate clearance in evaluating the survival rate and neurological outcome of patients with craniocerebral trauma. Methods The clinical data of 497 craniocerebral trauma patients admitted to our hospital from September 2017 to July 2018 were collected and retrospectively analyzed. Patients were divided into groups with different 6 h lactate clearance rates and admission lactate levels, and the differences in mortality and outcome of neurological function in each group were compared. Results The serum admission lactate levels、serum lactate levels at 6 hours, 28-day mortality and 28-day poor nerve function prognosis rate of patients with different 6h lactate clearance rates were statistically significant differences(P < 0. 05). The efficacy of 6h lactic acid to predict the mortality rate of patients was better than that of admission lactic acid and 6h lactate clearance rate (Z=3.71、Z=3.95,P<0.05). However, in predicting the neurological function of patients, the lactate clearance rate is not better than blood lactate level at any time(Z=1.30，Z=0.81，P>0.05). Conclusion 6h lactic acid has the best ability to judge the mortality of patients while lactic acid clearance rate is not better than the blood lactate level at any time in predicting the neurological function of patients.
ABSTRACT
PURPOSE: Ischemic stroke is rarely seen in children, but it could cause mortality and result in developmental disabilities such as motor paralysis, cognitive dysfunction, and epilepsy. In this study, the neurological outcomes of ischemic stroke in children were reviewed and the factors associated with the neurological outcomes were to be analyzed. METHODS: Medical records of patients younger than 15 years of age who were newly diagnosed with ischemic stroke between January 2006 and December 2016 in Chonnam National University Hospital were reviewed. RESULTS: This study consisted of 38 patients with ischemic stroke (male/female= 18/20, mean age=6 years 1 month±4 years 8 months). Neurological outcomes assessment was done at least 1 year after the onset of ischemic stroke. 10 patients (26.3%) had no neurological impairments. Motor paralysis was noted in 22 (57.9%), cognitive dysfunction was in 9 (23.7%), and epilepsy in 20 (52.6%). Among the possible risk factors for neurological impairments (age, sex, early seizures, characteristics of the infarcted lesions, abnormal electroencephalogram (EEG) findings), abnormalities on EEG findings were significantly associated with cognitive dysfunction (P=0.026) and the occurrence of early seizures with epilepsy (P=0.000). CONCLUSION: Neurological impairments were remained in 73.7% of children one year after ischemic stroke. Cognitive dysfunction was associated with abnormalities on EEG findings within 2 weeks after the onset of ischemic stroke and epilepsy with the occurrence of early seizures.

Objective To assess the effectiveness of pre-hospital therapeutic hypothermia after out-of-hospital cardiac arrest (OHCA) for survival and neuro-protection.Methods Databases such as Medline, ScienceDirect, Embase, Highwire, Cochrane Library, CNKI and Wanfang digital database were searched from January 2000 to March 2017 to retrieve randomized controlled trials (RCTs) on pre-hospital therapeutic hypothermia after OHCA. Thereafter, the studies retrieved were screened based on predefined inclusion and exclusion criteria. Data were extracted and the quality of the included studies was evaluated. A Meta-analysis was performed using the Cochrane Collaboration RevMan 4.3 software. Analysis of publication bias was depicted by funnel plot.Results Eight studies involving 3555 cases were included, among which 1804 cases were assigned to the treatment group and 1751 cases to the control group. Meta-analysis showed that compared with in-hospital therapeutic hypothermia, pre-hospital therapeutic hypothermia did not improve the survival rate of patients with OHCA [odds ratio (OR) = 1.00, 95％ confidence interval (95％CI) =0.85-1.18,P = 0.99], and neurological outcome at hospital discharge (OR = 0.97, 95％CI = 0.80-1.16,P = 0.71), but the body temperature was significantly lowered at admission [weighted mean difference (SMD) = -0.88, 95％CI = -1.03 to-0.73,P < 0.00001]. The funnel plot suggested that there was no publication bias in the 8 studies. But due to the low number of studies, the publication bias could not be completely excluded.Conclusion Pre-hospital therapeutic hypothermia after OHCA can decrease temperature at hospital admission, but cannot increase the survival rate and neurological outcome at hospital discharge.

ABSTRACT
PURPOSE: The purpose of this study is to examine the factors associated with neurological outcome and to provide ideas for improving the operation of the emergency medical system in Korea. METHODS: A total of 95,911 out-of-hospital cardiac arrests (OHCAs) with cardiac etiology who were transported by 119 EMS ambulances for seven years from 2006 to 2012 in Korea were analyzed. According to these data there is a multilevel structure, so that patient's neurological outcome in the same region is not independent but interrelated, therefore two-level (patient-region) logistic regression analysis was applied to adjust this correlation. RESULTS: The adjusted odds ratio (OR) in the group in which Cardiopulmonary Resuscitation (CPR) was performed by a bystander was 1.27 for good neurological outcome. The adjusted OR in the group with implementation of an automated external defibrillator (AED) before arrival at the hospital was 4.11 for good neurological outcome. The adjusted OR in the numbers of emergency physicians compared with <3 was 2.76 (3-4), 4.24 (≥5) and the adjusted OR in OHCAs volume of each hospital compared with <50 was 2.31 (50-64), 2.51 (65-102), and 2.94 (≥103). The adjusted OR in deprivation level compared with <2 was 0.72 (≥2). CONCLUSION: The neurological outcome was significantly better in the group in which CPR was performed by a bystander and AED was applied early. The neurological outcome tended to be significantly better in hospitals with higher numbers of emergency physicians and higher volume of OHCAs, in less deprived districts.

STUDY DESIGN: Retrospective case series. PURPOSE: To clarify the influence of cervical spinal canal stenosis (CSCS) on neurological functional recovery after traumatic cervical spinal cord injury (CSCI) without major fracture or dislocation. OVERVIEW OF LITERATURE: The biomechanical etiology of traumatic CSCI remains under discussion and its relationship with CSCS is one of the most controversial issues in the clinical management of traumatic CSCI. METHODS: To obtain a relatively uniform background, patients non-surgically treated for an acute C3-4 level CSCI without major fracture or dislocation were selected. We analyzed 58 subjects with traumatic CSCI using T2-weighted mid-sagittal magnetic resonance imaging. The sagittal diameter of the cerebrospinal fluid (CSF) column, degree of canal stenosis, and neurologic outcomes in motor function, including improvement rate, were assessed. RESULTS: There were no significant relationships between sagittal diameter of the CSF column at the C3-4 segment and their American Spinal Injury Association motor scores at both admission and discharge. Moreover, no significant relationships were observed between the sagittal diameter of the CSF column at the C3-4 segment and their neurological recovery during the following period. CONCLUSIONS: No relationships between pre-existing CSCS and neurological outcomes were evident after traumatic CSCI. These results suggest that decompression surgery might not be recommended for traumatic CSCI without major fracture or dislocation despite pre-existing CSCS.

The cerebral resuscitation is the most important aim in advanced cardiopulmonary cerebral resuscitation (CPCR). Cerebral function protection after cardiac arrest (CA) is important to improve survival rates including those after the discharge. Therapeutic mild hypothermia maybe the only method that can improve neurological function of patients following resuscitation after CA, which was recommended as one of treatment strategies for unconscious patients after successful resuscitation in 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care. Although there are many cooling methods of inducing hypothermia, each has some advantages or shortcomings. There were many controversies on the choice, which need further research. We make a summary and analysis about the mechanism of therapeutic mild hypothermia, the possible complications at different stages and the clinical application of mild hypothermia, such as the evaluation before therapeutic mild hypothermia and the choice of hypothermia protocol and cooling methods, to provide guidance for clinical mild hypothermia therapy.
ABSTRACT
Neurological outcome in critically ill neonates has become the focus of attention.Amplitude-integrated electroencephalography (aEEG),as a brain function examination of noninvasive and relatively simple operation,offers a variety of information for pediatricians while early applying to the critically ill newborus,and is helpful to predict the long-term neurological outcome.Currently,the increasing number of neonatal intensive care units are using aEEG as the neurological examination.
ABSTRACT
La hidrocefalia congénita unilateral es una malformación extremadamente infrecuente (1 por 1.411 embarazos) y rara vez detectada en el período prenatal. Se considera una entidad distinta a la hidrocefalia bilateral, en cuanto a morbilidad, mortalidad y pronóstico perinatal. En la hidrocefalia unilateral se reporta una sobrevida elevada y un resultado neurológico favorable cuando el grado de dilatación es leve, estable en el tiempo y no asociada a otras malformaciones. El diagnóstico prenatal se realiza mediante ecografía y resonancia magnética y es confirmado al nacimiento con ecografía, tomografía axial computada o resonancia magnética. No existen actualmente pautas estandarizadas para su manejo y seguimiento a largo plazo. Se presenta a continuación un caso clínico de diagnóstico antenatal de hidrocefalia congénita unilateral y la revisión de la literatura.
Congenital unilateral hydrocephalus is an extremely rare malformation (1 per 1,411 pregnancies), rarely detected in the prenatal period. It is considered a different entity than bilateral hydrocephalus, in terms of morbidity, mortality and perinatal outcome. Unilateral hydrocephalus has a high survival rate and favorable neurological outcome when dilatation is mild, stable over time and when not associated with other malformations. Prenatal diagnosis is performed by ultrasound and magnetic resonance imaging and confirmed at birth with ultrasound, CT sean or MRI. Not currently standard guidelines are available for management and long-term monitoring. We present a case report of antenatal diagnosis of congenital unilateral hydrocephalus and literature review.

OBJECTIVE: We aimed to identify clinico-radiological risk factors that may predict unfavorable neurological outcomes in traumatic brain injury (TBI), and to establish a guideline for patient selection in clinical trials that would improve neurological outcome during the early post TBI period. METHODS: Initial clinico-radiological data of 115 TBI patients were collected prospectively. Regular neurological assessment after standard treatment divided the above patients into 2 groups after 6 months : the Favorable neurological outcome group (GOS : good & moderate disability, DRS : 0-6, LCFS : 8-10) and the Unfavorable group (GOS : severe disability-death, DRS : 7-29 and death, LCFS : 1-7 and death). RESULTS: There was a higher incidence of age > or =35 years, low initial GCS score, at least unilateral pupil dilatation, and neurological deficit in the Unfavorable group. The presence of bilateral parenchymal lesions or lesions involving the midline structures in the initial brain CT was observed to be a radiological risk factor for unfavorable outcome. Multivariate analysis demonstrated that age and initial GCS score were independent risk factors. The majority of the Favorable group patients with at least one or more risk factors showed improvement of GCS scores within 2 months after TBI. CONCLUSION: Patients with the above mentioned clinico-radiological risk factors who received standard treatment, but did not demonstrate neurological improvement within 2 months after TBI were deemed at risk for unfavorable outcome. These patients may be eligible candidates for clinical trials that would improve functional outcome after TBI.

OBJECTIVE: To investigate the relationship between cognitive impairment and 1H magnetic resonance spectroscopy (1H MR spectroscopy) in patients with subarachnoid hemorrhage (SAH) caused by rupture of middle cerebral artery (MCA) aneurysm. METHOD: 1H MR spectroscopy was performed in 6 patients with SAH after rupture of MCA aneurysm and in 20 controls. Image-guided localized 1H MR spectra were obtained from left parietal white matter (PWM). The cognitive status was evaluated using the Mini Mental Status Examination (MMSE), and the scores were correlated with N-acetyl aspartate/creatine (NAA/Cr), choline/creatine (Cho/ Cr), and myoinositol/creatine (mI/Cr) metabolic ratios. RESULTS: NAA/Cr was significantly lower, and Cho/Cr was higher in SAH patients than in controls in the left PWM (p0.05). CONCLUSION: 1H MR spectroscopy could be helpful in the evaluation of cognitive impairment in SAH.

OBJECTIVE: Perinatal infarcts are an important cause of neonatal neurologic morbidity accounting up to 10~20% of neonatal seizures and annual incidence rate is about one in 4,000 live births. The purpose of this study is to describe the clinical presentation, course, radiologic and Electroencephlogram (EEG) findings and to evaluate the neurologic outcome of cerebral infarcts. METHODS: Between January 2000 to May 2004, 8 of 40,204 delivered newborns (0.02%) were diagnosed as having cerebral infarcts. The clinical presentation, course, radiologic and EEG findings were characterized by retrospective chart review and neurological outcome was evaluated by neurological examination and developmental test (Bayley Scales of Infant Development-II) at out-patient department. RESULTS: There were 5 males and 3 females. Six cases of them were full term, and other 2 cases were near-term neonates. Five cases presented neonatal seizure and 3 presented apnea or respiratory distress. All cases showed abnormal finding in the cranial ultrasonography that was performed immediately after the first symptoms. After then, diagnosis of cerebral infarct was confirmed by computed tomography and magnetic resonance imaging. Abnormal EEG finding was found in the 4 cases and a correlation between the location of these abnormalities and cerebral infarcts existed. The location of infarct was on the left hemisphere in five of the 8 cases and predominantly in the distribution of the middle cerebral artery. 7 cases were followed and the mean duration of follow up was 17 months (range 3~42 months). Neurologic outcome was normal in 3 cases and abnormal in 4 cases. Mild hemiparesis was present in 3 cases and recurrent epilepsy in 1 case. Developmental test was performed in 4 cases, all of them were normal. CONCLUSION: Neonatal seizure is an important presentation as the first sign of perinatal infarcts and cranial ultrasound can be used for initial evaluation of these perinatal infarcts. Neuological sequelae remains over half of the patients. Performing long term follow-up study of large cohort study is needed.

Subarachnoid hemorrhages (SAH) result in hemodynamic and metabolic abnormalities. The successful treatment of these abnormalities requires active treatment of neuroprotection. Recently, it has been known that albumin has important roles in neuroprotection as well as in hemodilution. We retrospectively studied 64 patients who were treated surgically for aneurysmal SAH to investigate the relationship between serum albumin levels, severity of disease and neurological outcomes. A high proportion of patients developed hypoalbuminemia after aneurysmal SAH. Patients with poor clinical presentation had significantly lower admission and postoperative albumin values than those with good clinical presentation. Comparison of patients with a favorable outcome and those with an unfavorable outcome revealed a significant difference in postoperative albumin values. In the patients with severe clinical presentation, postoperative albumin levels lower than 3.5 g/dL were associated with an unfavorable outcome. As a result of our analysis, albumin is an important prognostic factor in aneurysmal SAH. Therefore, active albumin replacement therapy might improve neurological outcomes as a neuroprotective agent. We therefore suggest that albumin offers great promise in the therapy of complications of SAH and we propose that it may now be appropriate to consider the initiation of early-phase clinical trials in patients with aneurymal SAH.

In an attempt to investigate the effect of intracerebral hematoma on cortical blood flow and perifocal ischemia, an experimental rat model of intracerebral hematoma was used. In a total of 44 adult male rats, cortical blood flow was studied using on H2 clearance method. The ischemic zone was investigated under light microscopy. In order to potentiate the effect of intracerebral hematoma, bilateral ligation of the common carotid artery was simultaneously performed in twelve rats. Intracerebral hematoma was induced by injecting 30nl of autologous arterial blood. Ipsilateral cortical blood flow decreased to 67.4% of baseline after the formation of intracerebral hematoma in the basal ganglia ; bilateral ligation of the common carotid artery alone decreased cortical blood flow to 59.4% of baseline ; and intracerebral hematoma formation after ligation decreased the flow to 20.5% of baseline. Neurological grades were worst in the last mentioned group, and in no group was perifocal infarction detected by light microscopy. These data suggest that the occurrence of intracerebral hematoma markedly decreases the cortical blood flow. Additionally, in a situation of compromised cerebral blood flow, the development of intracerebral hematoma can lead to a further decrease in flow, resulting in a worse neurological outcome, despite the absence of detectable histological difference.

The mortality rate of aneurysmal surgery had recently been reduced due to modern microsurgical technique and refinement of the timing of operation. Despite recovery without neurological deficits, many patients remain with emotional and psychological sequelae postoperatively. We evaluated 33 patients, operated on intracranial aneurysm for recent 2 years, about quality of life and degree of cognitive function. For proper evaluation of outcome of aneurysmal surgery, in addition to the neurological outcome, psychological aspects must be considered.
