Purpose: The incidence of glufosinate poisoning is gradually increasing, and it can be fatal if severe poisoning occurs. However, factors useful for predicting the post-discharge neurological prognosis of patients who have ingested glufosinate have yet to be identified. Our objective was to evaluate the utility of the acute physiology and chronic health evaluation (APACHE) II score measured in the emergency department for predicting the neurological prognosis. Methods: From April 2012 to August 2014, we conducted a retrospective study of patients who had ingested glufosinate. The outcome of the patients at discharge was defined by the Cerebral Performance Category Score (CPC). The patients were divided into a good prognosis group (CPC 1, 2) and a poor prognosis group (CPC 3, 4, 5), after which the APACHE II scores were compared. The Hosmer-Lemeshow test and the area under the receiver operating characteristic (ROC) curve from patients determined calibration and discrimination. Results: A total of 76 patients were enrolled (good prognosis group: 67 vs poor prognosis group: 9). The cut-off value for the APACHE II score was 12 and the area under the curve value was 0.891. The Hosmer and Lemeshow C statistic x2 was 7.414 (p=0.387), indicating good calibration for APACHE II. Conclusion: The APACHE II score is useful at predicting the neurological prognosis of patients who have ingested glufosinate.
Objective : Although surgical intervention, such as percutaneous vertebroplasty (PVP), is the standard treatment for osteoporotic vertebral compression fractures (OVCFs), its effectiveness and safety are unclear. Therefore, this study compared the safety and efficacy of conservative treatment with that of PVP for acute OVCFs. Methods : Patients with single-level OVCFs who were treated conservatively with a transdermal fentanyl patch (TFP) or with PVP between March 2013 and December 2017 and followed-up for more than 1 year were retrospectively evaluated. Patients with pathologic fractures, fractures of more than two columns, or a history of PVP were excluded. Clinical outcomes (visual analog scale [VAS] scores) and radiographic factors were evaluated, including changes in the compression rate of the corresponding vertebral body at onset and after 12 months, sagittal Cobb angle at onset and after 6 and 12 months, and the incidence of adjacent compression fractures. Results : Of the 131 patients evaluated, 75 were treated conservatively using TFPs and 56 underwent PVP. We divided the patients into TFP and PVP groups. Their baseline characteristics (including sex, level of fracture, and bone mineral density T-scores) were similar, but the TFP group was significantly younger. The overall VAS score for pain showed a greater decrease during the first month (1 week after PVP) in the PVP group but remained similar in the two groups thereafter. The compression rate after 12 months increased in the TFP group but decreased in the PVP group. Five patients in the PVP group, but none in the TFP group, experienced adjacent compression fractures within 12 months. Conclusion : We compared clinical and radiological outcomes between the TFP and PVP groups. The immediate pain reduction effect was superior in the PVP group, but the final clinical outcome was similar. Although the PVP group had a better-preserved compression rate than the TFP group for 1 year, the development of adjacent fractures was significantly higher. Although TFPs seemed to be beneficial in reducing the failure rate of conservative treatment, the possibility of side effects (22.6%, 17 out of 75 patients, in this study) should be carefully monitored.

Purpose: A recent study analyzing several cytokines reported that long cardiopulmonary bypass (CPB) time and long aortic cross clamp (ACC) time were accompanied by enhanced postoperative inflammation, which contrasted with the modest influence of the degree of hypothermia. In this present study, we aimed to examine the effect of CPB temperature on the clinical outcome in infants undergoing repair of isolated ventricular septal defect (VSD). Methods: Of the 212 infants with isolated VSD who underwent open heart surgery (OHS) between January 2001 and December 2010, 43 infants were enrolled. They were classified into 2 groups: group 1, infants undergoing hypothermic CPB ($26^{\circ}C-28^{\circ}C$; n=19) and group 2, infants undergoing near-normothermic CPB ($34^{\circ}C-36^{\circ}C$; n=24). Results: The age at the time of the OHS, and number of infants aged<3 months showed no significant differences between the groups. The CPB time and ACC time in group 1 were longer than those in group 2 (88 minutes vs. 59 minutes, P =0.002, and 54 minutes vs. 37 minutes, P =0.006 respectively). The duration of postoperative mechanical ventilation was 1.6 days in group 1 and 1.8 days in group 2. None of the infants showed postoperative neurological and developmental abnormalities. Moreover, no postoperative differences in the white blood cell count and C-reactive protein levels were noted between two groups. Conclusion: This study revealed that hypothermic and near-normothermic CPB were associated with similar clinical outcomes and inflammatory reactions in neonates and infants treated for simple congenital heart disease.
Objective : The use of segmental instrumentation technique using pedicle screw has been increasingly popular in recent years owing to its biomechanical stability. Recently, intralaminar screws have been used as a potentially safer alternative to traditional fusion constructs involving fixation of C2 and the cervicothoracic junction including C7. However, to date, there have been few clinical series of C7 laminar screw fixation in the literature. Thus, the purpose of this study is to report our clinical experiences using C7 laminar screw and the early clinical outcome of this rather new fixation technique. Methods : Thirteen patients underwent C7 intralaminar fixation to treat lesions from trauma or degenerative disease. Seventeen intralaminar screws were placed at C7. The patients were assessed both clinically and radiographically with postoperative computed tomographic scans. Results : There was no violation of the screw into the spinal canal during the procedure and no neurological worsening or vascular injury from screw placement. The mean clinical and radiographic follow up was about 19 months, at which time there were no cases of screw pull-out, screw fracture or non-union. Complications included two cases of dorsal breech of intralaminar screw and one case of postoperative infection. Conclusion : Intralaminar screws can be potentially safe alternative technique for C7 fixation. Even though this technique cannot be used in the cases of C7 laminar fracture, large margin of safety and the ease of screw placement create a niche for this technique in the armamentarium of spine surgeons.
Purpose: The purpose of this study was to determine the effect of TENS by physiotherapist versus home based TENS intervention to reduce pain and improve disability in patients with mechanical neck disorder. Methods: The subjects of the study were 30 selected patients who had been diagnosed with subacute or chronic neck disorders without neurological damage, during the period of four weeks, three times a week, and thirty minutes for one session, 15 patients received TENS by physiotherapist. 15 patients received home based TENS intervention. The primary outcome was pain intensity measured in using the Visual Analog Scale(VAS). The second outcome was Neck Disability Index to patient's disability. Results: The change in the pain perception degree were statistically significant in both group(p<0.05). TENS by physiotherapist group showed significantly improvement in disability, but, Home based TENS intervention group is not. TENS by physiotherapist group showed significantly greater improvement in pain intensity and patient's disability than the home based TENS intervention group. Conclusion: This study shows that received TENS by physiotherapist was effective in reducing pain, improving disability for mechanical neck disorder patient, physiotherapist' knowledge need to improve patient's pain and disability.

Objective : The treatment of giant cell tumor (GCT) is mainly performed surgically. However, GCT in spine seems difficult to treat because of the limited surgical accessibility and proximity. In this report, we analyzed the outcome of GCT treatment in spine. Methods : Between 2000 and 2012, 19 patients received treatment for GCT in spine. Median age at their first diagnosis was 31 years, 10 patients were male, and 9 female. Fourteen tumors were located in the sacrum, 1 in cervical, 1 in thoracic and 3 in lumbar spine. As primary treatment, gross total removal (GTR) was done in 6 patients, and subtotal removal (STR) in 13 patients. Radiation therapy (RT) as an adjuvant therapy was performed in 2 cases in GTR group and 10 cases in STR group. Results : During the follow-up, 7 patients had local recurrence (36.8%). The average period until recurrence after primary treatment was 14 months. No recurrence was detected in GTR group. Recurrence was noted in 7 out of 13 patients who underwent STR. These differences were statistically significant (p=0.024). A median of recurrence free period (RFP) was 84 months. Also average RFP of the RT group was 112 months, and non-RT group was 65 months. These differences were statistically significant (p=0.041). Conclusion : Treatment of choice for GCT in spine is a complete removal of tumor without neurological deficits. In case of incomplete removal, radiation therapy may be a useful adjuvant treatment modality.
Objective : The purpose of this study was to review the characteristics of falcine meningioma retrospectively and to identify the parameters associated with tumor recurrence. Methods : The analysis included; age, sex, extent of resection, and radiologic and pathologic findings. Falcine meningiomas were classified by location as anterior, middle, or posterior as described for parasagittal meningiomas. Results : Of the 795 meningioma patients treated between 1990 and 2004 at the authors' institution, 68 patients with meningiomas arising from the falx underwent craniotomies. There were 22 male and 46 female patients (1:2.1). Mean age was 55 years and ranged from 14 to 77 years. Locations of falcine meningioma were; the anterior third in 33 cases, middle in 20, and posterior in 15. Mean tumor volume was 42 cc and ranged from 4 to 140 cc. In 58 of the 68 patients tumors were totally removed. Additional surgery for recurrence was performed in 6 patients over 15 years. Of these 6 patients, only two patients underwent gross total tumor resection at first operation; the other four underwent subtotal tumor resection. Based on pathologic reports, the largest tumor subtype was transitional. There were four patients with a high grade tumor-three atypical and one anaplastic meningioma. Of the 68 patients, 59 achieved a good outcome (no neurological deficit or recurrence), six had temporary complications, two suffered new permanent postoperative deficits, and the remaining one died due to severe brain swelling despite postoperative intensive care. Extent of surgical resection was found to be significantly related to tumor recurrence. Conclusion : Falcine meningioma accounted for 8.5% of intracranial meningiomas and the transitional meningioma was the most common subtype of falcine meningioma. Gross total resection of tumor was the single most important predictor of an improved surgical outcome.
Objective : This study was designed to analyze surgical strategies for patients with intractable supplementary sensorimotor area[SSMA] seizures. Methods : Seventeen patients who had surgical treatment were reviewed retrospectively. Preoperatively, phase I [non-invasive] and phase II [invasive] evaluation methods for epilepsy surgery were done. Seizure outcome was assessed with Engel's classification. The mean follow-up period was 27.2 months [from 12 months to 54 months]. Results : An MRI identified structural abnormality in eight patients and 3D-surface rendering revealed abnormal gyration in three. PET, SPECT, and surface EEG could not delineate the epileptogenic zone. Video-EEG monitoring with a subdural grid or depth electrodes verified the epileptogenic zone in all patients. Surgical procedures consisted of a resection of the SSMA and simultaneous callosotomy in two patients, a resection of the SSMA extending to the adjacent area in seven, a resection of a different area without a SSMA resection in seven, and a callosotomy in one. Seizure outcomes were class I in 11 [65%]. class II in five [29%], class III in one [6%]. Conclusion : In patients with intractable SSMA seizure, surgery was an excellent treatment modality. Precise delineation of the epileptogenic zone based on multimodal diagnostic methods can provide good surgical outcomes without neurological complications.
Objective : The incidence of aneurysmal subarachnoid hemorrhage has been increasing. At the same time, surgical results for elderly patients are unsatisfactory and no guidelines of treatment are available. We carried out a study comparing variable factors and surgical results between young and old age groups to find ways to improve prognosis. Methods : A retrospective study was carried out on 754 patients who were operated on between 1990 and 2004 by the same surgeon in our hospital. The patients were divided into seven groups according to age : 93 patients below 40 years of age [Group I], 419 patients aged $40{\sim}59$ [Group II], 115 patients aged $60{\sim}64$ [Group III], 82 patients aged $65{\sim}69$ [Group IV], 28 patients aged $70{\sim}74$ [Group V], 12 patients aged $75{\sim}79$ [Group VI] and 5 patients over the age of 80 [Group VII]. We then checked their medical history, Fisher's grade, Hunt-Hess grade, postoperative complications, and Glasgow Outcome Scale. Results : Age was not a statistically significant factor among patients below 70 years of age [P $value{\ge}0.05$]. But for those aged 70 and older, the age factor had a statistical value [P $value{\le}0.001$]. In addition, there was a close correlation between Hunt-Hess grade IV and V patients, and those with vasospasm, and hydrocephalus after surgery, with poor prognosis in elderly patients as well as young patients [P $value{\le}0.001$]. Conclusion : Advanced age [under the age of 70] dose not precluded adequate surgical treatment in patient with AN SAH, and we should be also alert to preventable causes of delayed neurological deterioration for improving the outcome in all elderly groups.
Objectives : The percutaneous vertebroplasty provides a good result in the treatment of osteoporotic vertebral compression fractures. But, the epidural leakage of polymethylmetacrylate(PMMA) after vertebroplasty may decrease the therapeutic effects because of the compression of thecal sac and/or nerve roots. The authors carried out a prospective study to evaluate the causative factors of epidural leakage of PMMA and to assess the influence on the outcome. Methods : This study involved 347 vertebral levels of compression fractures in 159 patients. Among these, the epidural leakages were identified in 92 vertebral levels(26.5%) in 64 patients(40.3%) on post-operative CT scan. Results : The incidence of epidural leakage of PMMA was significantly higher in the level above T7(p=0.001). The large amount of the injected PMMA and the use of an injector also increased the incidence(p=0.03 and p=0.045, respectively). The position of the needle tip in the vertebral body and the pattern of venous drainage did not influence. The immediate post-operative visual analogue scale(VAS) scores and facial scales(FS) were higher in the patients with epidural leakage(p=0.009). But there were no significant differences between the two groups after three months of operation(p=0.541). Conclusions : The incidence of epidural leakage of PMMA after percutaneous vertebroplasty appears to have relationship with the amount of PMMA and the levels injected. The epidural leakage of PMMA reduced the immediate therapeutic effects of vertebroplasty, but did not influence the late outcome. However, the epidural leakage should be avoided because of its potential neurological complications.
