The application of stereotactic techniques and endoscopy dates back to the beginning of this century and is almost as old as neurosurgery itself. However, endoscopic techniques progressed slowly for several reasons. A reappraisal of endoscopic techniques become popular about 1985. The major indication of endoscope in neurosurgical field is intraventricular procedures. Recently it can be used selectively in the intraaxial mass lesion associated cavity. For example, cystic mass, with liquefied necrosis, blood clot can be approached with endoscope. Authors present its intraaxial application in basal ganglionic hematoma in three patients. Conventional stereotactic guidance of neuroendoscope was done and the hematoma was gently removed through continuous irrigation and suction under video-guidance. The clinical course was uneventful. Brief overview is given of this intraaxial neuroendoscopic procedure.

OBJECTIVE: This study is performed to compare the clinical courses (feature, treatment and outcomes) in patients with negative versus positive culture result in pyogenic spondylodiscitis. METHODS: From January 2001 to December 2006, we reviewed clinical data in 26 consecutive patients with pyogenic spondylodiscitis retrospectively. We exclude patients that underwent surgical irrigation or debridement with biopsy. We measured clinical outcomes, length of antibiotic administration, recurrence rate, laboratory studies (CRP, ESR and leukocyte counts) and complications between two groups. Clinical outcomes were rated with Macnab's criteria. RESULTS: Causative organisms were confirmed in 6 cases and the other 20 cases had negative culture result. Mean follow-up duration was 13 months. Mean intravenous antibiotics administration duration of patients having negative culture result was 8.4 weeks and oral was 5 months. On the other hand, in cases of positive culture result, mean intravenous duration was 8.7 weeks and oral was 5.2 months. Initial mean ESR and CRP were elevated, and decreased in both groups according to antibiotics medication (p<0.001 and p=0.001). But initial mean WBC count was normal range. There was no difference in tendencies of decrement of ESR and CRP between two groups (p=0.61 and p=0.571). Clinical outcomes (p=0.231) and complications (p=0.558) were not significantly different. There were no recurrence case for followup period. CONCLUSION: Negative culture results did not significantly affect the clinical course of pyogenic spondylodiscitis when we compared the clinical courses of both groups.

Botulinum toxin type A(BTA) is well known treatment agent in the treatment of paralytic strabismus in ophthalmological field for more than 15 years. Its therapeutic potential as temporary paralyzing agent was adopted to treat several neurologic, movement disorders. In recent years, BTA is considered as initial medical treatment option in such as blepharospasm, hemifacial spasm, spasmodic torticollis, spasmodic dysphonia. Authors applied BTA injection in cases with spasmosmodic torticollis, hemifacial spasm, facial synkinesis and experienced staisfactory result. So authors present our experience of BTA injection therapy and discuss techniques, advantages and disavantages.

Intradural extramedullary (IDEM) ependymomas occur very rarely and little has been reported about their clinical characteristics. The authors present a case of a 57-year-old woman with an IDEM ependymoma. She was referred for the evaluation of a 4-month history of increasing neck pain and muscular weakness of the left extremities. Magnetic resonance imaging (MRI) of the cervical spine demonstrated an IDEM tumor with spinal cord compression. At the time of surgery, an encapsulated IDEM tumor without a dural attachment or medullary infiltration was noted, but the tumor capsule adherent to the spinal cord and root was left in place to minimize the risk of neurological sequelae. Histologic examination revealed a benign classic ependymoma. The post-operative course was uneventful and radiotherapy was performed. The patient showed an excellent clinical recovery, with no recurrence after 5 years of follow-up.

OBJECTIVE: The purpose of this prospective study was to evaluate the effects of body mass index (BMI) on intra-abdominal pressure (IAP) and intraoperative blood loss (IBL) during lumbar spinal surgery. METHODS: Thirty patients scheduled for single level posterior lumbar interbody fusion were allocated equally to a normal group (Group 1, BMI;18.5-22.9 kg/m2), an overweight group (Group 2, BMI; 23-24.9 kg/m2), and an obese group (Group 3, BMI; 25.0-29.9 kg/m2) according to BMI. IAP was measured using a urinary bladder catheter; 1) supine after anesthesia induction, 2) prone at skin incision, 3) prone at the end of surgery. In addition, IBL was also measured in the three groups. RESULTS: IAP in the supine position was not significantly different in groups 1, 2, and 3 (2.7 mm Hg, 3.0 mm Hg, and 4.2 mm Hg, respectively) (p=0.258), and IAP in the prone position at incision increased to 7.8 mm Hg, 8.2 mm Hg, and 10.4 mm Hg, respectively, in the three groups, and these intergroup differences were significant, especially for Group 3 (p=0.000). IAP at the end of surgery was slightly lower (7.0 mm Hg, 7.7 mm Hg, and 9.2 mm Hg, respectively). IBLs were not significantly different between the three groups. However, IBLs were found to increase with IAP in the prone position (p=0.022) and BMI (p<0.05). CONCLUSION: These results show that BMI affects IAP in the prone position more than in the supine position during lumbar spinal surgery. In addition, IBLs were found to increase with IAP in the prone position and with BMI. Thus, IBLs can be expected to be higher in morbidly obese patients due to an increased IAP.

Simultaneous development of intrahepatic bile duct and gallbladder carcinoma is extremely rare. We report herein the case of an 86-year-old man found to have double cancer of the gallbladder and intrahepatic bile duct. Computed tomography and magnetic resonance cholangiopancreatography revealed a polypoid mass in the gallbladder and dilatation of the intrahepatic bile duct with intraductal papillary tumor in the left side of the liver. The patient underwent left hepatectomy, cholecystectomy with lymphadenectomy around the hepatoduodenal ligament. Pathological examination of the gallbladder revealed undifferentiated giant cell type carcinoma invading the muscularis propria. On the other hand, the liver tumor was intrahepatic intraductal papillary mucinous carcinoma in situ. Therefore, this was an extremely rare case of synchronous carcinoma of the gallbladder associated with intrahepatic cholangiocarcinoma.

Background:
The purpose of this study was to assess the reliability and validity of the 3-item version of the Work Engagement Scale (WES-3), which is based on the Job DemandsResources (JD-R) model and was used in the 5 th Korean Working Conditions Survey (KWCS).
Methods:
This study used data from the 5th KWCS (n = 50,205), which was conducted in 2017 with a sample of the Korean working population. The survey gathered comprehensive information on working conditions to define workforce changes and the quality of work and life. The reliability and internal consistency of the WES-3 were assessed using the corrected item-total correlation and Cronbach's alpha coefficient. Confirmatory factor analysis (CFA) was used to test the construct validity of work engagement. The convergent validity was assessed using the correlation with the WHO-5 well-being index. Correlations between work engagement and JD-R factors were also calculated.
Results:
The Cronbach's alpha for work engagement was 0.776, indicating acceptable internal consistency. The model comprising 3 work engagement and 2 burnout items showed an excellent fit (χ2 : 382.05, Tucker-Lewis index: 0.984, comparative fit index: 0.994, root mean square error of approximation: 0.043). The convergent validity was significant (correlation coefficient: 0.42). Correlations with burnout and job demands were negligible, whereas correlations with job resources and job satisfaction were weakly positive.
Conclusions
The results of our study confirm that the WES-3 has acceptable reliability and validity.
