PURPOSE: To investigate the molecular responses of various genes and proteins related to disc degeneration upon treatment with cytokines that affect disc-cell proliferation and phenotype in living human intervertebral discs (IVDs). Responsiveness to these cytokines according to the degree of disc degeneration was also evaluated. MATERIALS AND METHODS: The disc specimens were classified into two groups: group 1 (6 patients) showed mild degeneration of IVDs and group 2 (6 patients) exhibited severe degeneration of IVDs. Gene expression was analyzed after treatment with four cytokines: recombinant human bone morphogenic protein (rhBMP-2), transforming growth factor-beta (TGF-beta), interleukin-1beta (IL-1beta), and tumor necrosis factor-alpha (TNF-alpha). Molecular responses were assessed after exposure of cells from the IVD specimens to these cytokines via real-time polymerase chain reaction and immunofluorescence staining. RESULTS: mRNA gene expression was significantly greater for aggrecan, type I collagen, type II collagen, alkaline phosphatase, osteocalcin, and Sox9 in group 1 than mRNA gene expression in group 2, when the samples were not treated with cytokines. Analysis of mRNA levels for these molecules after morphogen treatment revealed significant increases in both groups, which were much higher in group 1 than in group 2. The average number of IVD cells that were immunofluorescence stained positive for alkaline phosphatase increased after treatment with rhBMP-2 and TGF-beta in group 1. CONCLUSION: The biologic responsiveness to treatment of rhBMP-2, TGF-beta, TNF-alpha, and IL-1beta in the degenerative living human IVD can be different according to the degree of degeneration of the IVD.

OBJECTIVE: To verify the clinical outcomes of posterior C2-C3 fixation for unstable Hangman's fracture compared with posterior C1-C3 fixation. METHODS: Twenty four patients for unstable Hangman's fracture were enrolled between July 2007 and June 2010 in this study. Thirteen patients underwent posterior C2-C3 fusion and 11 patients underwent posterior C1-C3 fusion. Clinical outcomes were evaluated using Neck Disability Index (NDI) scores and Visual Analogue Scale (VAS) scores during preoperative and postoperative follow up period. Plain radiographs were obtained on postoperative 1 day, 1 week, and then at 1, 2, 6, and 12 months. CT was done at postoperative 12 months in all patients for evaluation of bone fusion. The mean period of clinical follow-up was 15 months. RESULTS: The mean ages were 43.3 years in C2-C3 group and 50.0 years in C1-C3 group. Mean follow-up period was 17.2 months in C2-C3 group and 16.3 months in C1-C3 group. VAS scores and NDI scores in C2-C3 group were much less than those in C1-C3 group at each follow-up period. The differences of VAS score and NDI scores between C2-C3 and C1-C3 groups at each follow-up period were statistically significant (p<0.001) by paired T-test. Solid Bone fusion was confirmed in all cases at the final follow-up. CONCLUSION: C2-C3 group showed better clinical and biomechanical results than C1-C3 group in terms of axial pain and disability of neck.

Primary spinal cord melanoma is a rare central nervous system malignant tumor. Usually it resembles an intradural extramedullary (IDEM) nerve sheath tumor or melanoma. We experienced a patient with upper thoracic primary IDEM spinal cord melanoma who was diagnosed to be with hydrocephalus and without intracranial lesions. Initial symptoms of the patient were related to the hydrocephalus and the primary spinal cord melanoma was diagnosed eight months later. At the first operation, complete resection was impossible and the patient refused additional radiotherapy or chemotherapy. At 22 months after surgery, the patient revisited our institution with recurrent both leg weakness. Leptomeningeal dissemination was present in the whole spinal cord and only partial resection of tumor was performed. The symptoms slightly improved after surgery. Primary spinal cord melanoma is extremely rare but complete resection and additional radiotherapy or chemotherapy can prolong the disease free interval. Hydrocephalus or signs of increased intracranial pressure may be the diagnostic clue of spinal cord malignancy and progression.

OBJECTIVE: To evaluate radiologic result of anterior cervical discectomy and fusion with allobone graft and plate augmentation, and the change of radiologic outcome between screw type and insertion angle. METHODS: Retrospective review of clinical and radiological data of 29 patients. Segmental angle, height and screw angles were measured and followed. The fusion rate was assessed by plain radiography and CT scans. We divided the patients into two groups according to screw type and angles. Group A: fixed screw, Group B: variable screw. Interscrew angle was measured between most upper and lower screws with Cobb's methods. RESULTS: Overall fusion rate was 86.2% on plain radiography. Fusion was also assessed by CT scan and Bridwell's grading system. There was no difference in fusion and subsidence rates between two groups. Subsidence was found in 5 patients (17.2%). Segmental lordotic angle was increased from preoperative status and maximized at the immediate postoperative period and then reduced at 1 year follow up. Segmental height showed similar increase and decrease values. CONCLUSION: ACDF with allograft and plate showed favorable fusion rates, and the screw type and angle did not affect results of surgery.

OBJECTIVE: This is a retrospective review of 22 surgically treated benign and malignant tumors of brachial plexus region to describe clinical presentation, the characteristics of brachial plexus tumor and clinical outcomes with a literature review. METHODS: Twenty-one patients with consecutive 22 surgeries for primary brachial plexus tumors were enrolled between February 2002 and November 2011 were included in this study. The medical records of all patients were reviewed. RESULTS: Eleven male and 10 female patients were enrolled. Mean age was 39 years. Three patients had brachial plexus tumor associated with neurofibromatosis (13.6%). Presenting signs and symptoms included parenthesis and numbness (54.5%), radiating pain (22.7%), direct tenderness and pain (27.2%), palpable mass (77.3%). Twelve patients presented preoperative sensory deficit (54.5%) and 9 patients presented preoperative motor deficit (40.9%). Twenty tumors (90.9%) were benign and 2 tumors (9.1%) were malignant. Benign tumors included 15 schwannomas (68.2%), 4 neurofibromas (18.2%) and 1 granular cell tumor (4.5%). There were 1 malignant peripheral nerve sheath tumor (MPNST) and 1 malignant granular cell tumor. Gross total resection was achieved in 16 patients (72.7%), including all schwannomas, 1 neurofibroma. Subtotal resection was performed in 6 tumors (27.3%), including 3 neurofibromatosis associated with brachial plexus neurofibromas, 1 MPNST and 2 granular cell tumor in one patient. CONCLUSION: Resection of tumor is the choice of tumor in the most of benign and malignant brachial plexus tumors. Postoperative outcomes are related to grade of resection at surgery and pathological features of tumor.

OBJECTIVE: This is prospective study of clinical outcomes of percutaneous plasma disc coagulation Therapy (PDCT) in patients with herniated lumbar disc disease (HLD) to evaluate the safety and efficacy in its clinical application and usefulness as a reliable alternative to microscopic discectomy. METHODS: Forty-six patients were enrolled in this study from April 2006 to June 2010. All patients had one-level HLD. Disc degeneration was graded on routine T2-weighted magnetic resonance Image (MRI) using the Pfirrmann's grading system and all index levels were grade 3 and grade 4. Indications for surgery were radiculopathy caused by disc protrusion with soft consistency. MRI was done at one month after the procedure in all patients to check post-PDCT change. The clinical outcomes were evaluated using Visual Analog Scales (VAS) score and MacNab's criteria. RESULTS: This study was approved by the Institutional Review Board of our institution. The age of the study population ranged from 16 to 59 years with a mean age of 37.2 years. There were 29 males and 17 females in this study. The mean period of clinical follow-up was 21 months. The average preoperative VAS score for radiculopathy was 7.4+/-1.4, while the final follow-up VAS score was 1.4+/-0.7 (p<0.001). In MacNab's criteria, 41 patients (89.1%) had achieved favorable improvement (excellent and good) until later follow-up. There were one patient from infection and two patients who needed to convert to open discectomy. CONCLUSION: PDCT is a safe and efficient treatment modality in a selective patient with HLD.

We present a patient with multifocal symptomatic osseous chordomas having unusual growth patterns with review of the pertinent literature. The patient was 62-year-old male and had multiple osseous chordomas located in sacral, thoracic, and paraclival jugular foramen areas. There was no metastasis in other organs. All affected sites were osseous. The multicentric chordomas are extremely rare. This case could be considered as a chordoma involving multiple neuraxial bones. But, the possibility of multicentricity could also be thought. In such cases radical resection should be performed for each lesion at the initial diagnosis. If complete surgical resections are infeasible or impossible, preoperative or postoperative radiation therapy should be planned for the highest possibility of successful treatment.

OBJECTIVE: This is retrospective study of clinical and radiological outcomes of anterior cervical fusion using Bongros-HA(TM) (BioAlpha, Seongnam, Korea) which is a type of synthetic hydroxyapatite (HA) spacer to evaluate the efficacy in its clinical application and usefulness as a reliable alternative to autograft bone. METHODS: Twenty-nine patients were enrolled in this study and 40 segments were involved. All patients were performed anterior cervical interbody fusion using HA spacer and plating system. Indications for surgery were radiculopathy caused by soft-disc herniation or spondylosis in 18 patients, spondylotic myelopathy in 1 patient, and spinal trauma in 10 patients. Cervical spine radiographs were obtained on postoperative 1day, 1week, and then at 1, 2, 6, and 12 months in all patients to evaluate intervertebral disc height, and the degrees of lordosis. Cervical computed tomography was done at postoperative 12 month in all patients to confirm the fusion status. The mean period of clinical follow-up was 17 months. RESULTS: Complete interbody fusion was achieved in 100% of patients. Preoperative kyphotic deformities were corrected in all cases after surgery. Intervertebral disc height was well maintained during follow up period. There were no cases of graft extrusion, graft deterioration and graft fracture. CONCLUSION: HA spacer is very efficient in achieving cervical fusion, maintaining intervertebral disc height, and restoring lordosis. When combined with the placement of a cervical plate, immediate stability can be achieved and graft related complication can be prevented.

Spontaneous spinal epidural hematoma (SSEH) is rare in children, especially in infants, in whom only 12 cases have been reported. Because of the nonspecificity of presenting symptoms in children, the diagnosis may be delayed. We report herein a case of SSEH in a 20-month-old girl who initially presented with neck pain, and developed lower extremity motor weakness and symptoms of neurogenic bladder 2 weeks prior to admission. The magnetic resonance imaging showed an epidural mass lesion extending from C7 to T4, and the spinal cord was severely compressed by the mass. After emergency decompressive surgery the neurologic function was improved immediately. Two months after surgery, the neurological status was normal with achievement of spontaneous voiding. We suggest that surgical intervention can provide excellent prognosis in case of SSEH in infants, even if surgery delayed.

OBJECTIVES: This study is designed to evaluate the fusion rate of anterior cervical discectomy and fusion (ACDF) using prefilled cage, and clinical features in patients with traumatic cervical injury. METHODS: Sixteen trauma patients at a single institute who underwent ACDF with prefilled cage and rigid plate fixation were evaluated for radiographic fusion status postoperatively every 1 month, 3 month, and 6 month after the surgery. ACDFs were done in 9 patients at one level, 3 patients at two levels, 3 patients at three levels, and 1 patient at four levels. Fourteen patients had fracture and instability, and 2 patients had traumatic herniated cervical discs without fracture and instability. Plain radiographs and CT scan were done for evaluation of bone fusion in all patients. RESULTS: Bone fusion was recognized in all patients. Intervertebral disc height was well maintained during follow-up period. There was no patient with graft failure and instability. Even though the patients with fracture and instability, there was no patient who needed posterior stabilization. There was one case of subsidence without clinical symptom which was needed additional surgical treatment. CONCLUSION: In the treatment of the patients with traumatic cervical diseases, prefilled cage is very effective to achieve cervical spinal stability after ACDF, and to maintain intervertebral disc height. We can achieve immediate postoperative stability and prevent graft displacement by reinforcement with cervical plate and screws.

Although lumbosacral lipoma is reported to occur in 4-8 of 100,000 patients, and 66% of lipomyelomeningoceles in young patients are accompanied by hypertrophic filum terminale, it is very rare to find two isolated spinal lipomas simultaneously. A 3 month-old baby girl was admitted to the hospital for a protruding, non-tender, soft, subcutaneous 2.5 cm mass of the lumbosacral area that had been present since birth. Simple radiography showed a spinal posterior arch defect from L3 to L5, and magnetic resonance imaging (MRI) demonstrated two isolated spinal lipomas, a transitional type from L3 to L5, and a terminal type below S1 without dural defect. The cornus medullaris was severely tethered descending to the S1, but there was no cerebellar or brain stem herniation on the MRI. We suggest that the presence of a combined spinal lipoma should be a point for careful differentiation in an infant with spinal lipoma.

OBJECTIVE: There is no acceptable indication and treatment of choice for infantile and child subdural hygroma and there are only a few reports about that in Korea. So the authors studied the clinical findings of infantile and child patients with subdural hygroma to improve the understanding and to suggest a standard treatment method. METHODS: The authors retrospectively evaluated the causes, preoperative symptoms, radiological thicknesses, and postoperative results of 25patients with subdural hygroma who received surgical therapy. RESULTS: There were 16boys and 9girls whose median age was 6months(range 2~120months). The main clinical manifestations were seizures, increased intracranial pressure, macrocrania and alteration of consciousness. Radiological thicknesses of the subdural hygroma varied from 7mm to 42mm and postoperative changes of thickness(y) could be expressed with the factor of month(x): y = -1.32 x +11.8 in subdural drainage, and y = -1.52 x +14.9 in subduroperitoneal shunts. Of the 25patients, 2 (50%) were successfully treated by aspiration, 13 (59%) by subdural drainage, and 9 (69%) by subduroperitoneal shunt. CONCLUSION: It is suggested that the diagnosis and treatment of subdural hygroma in infants and children should be carefully addressed because of its high prevalence in children, and especially in infants. It is also suggested that the subdural drainage could be primary initial treatment method because it is simpler than a shunt, and since our data show that there is no statistical difference in postoperative recovery duration between the two operative methods.

The authors developed a biodegradable polymer that releases an antibiotic (nalidixic acid) slowly and continuously, for prevention of catheter-induced infection during drainage of cerebrospinal fluid. We investigated the in vitro antibiotic releasing characteristics and bacterial killing effects of the new polymer against E. coli. The novel fluoroquinolone polymer was prepared using diisopropylcarbodiimide, poly (e-capro-lactone) diol, and nalidixic acid. FT-IR, mass spectrometry, and elemental analysis proved that the novel antibacterial polymer was prepared successfully without any side products. Negative MS showed that the released drug has a similar molecular weight (M.W.=232, 350) to pure drug (M.W.=232). In high pressure liquid chromatography, the released drug and drug-oligomer showed similar retention times (about 4.5-5 min) in comparison to pure drug (4.5 min). The released nalidixic acid and nalidixic acid derivatives have antibacterial characteristics against E. Coli, Staphylococcus aureus, and Salmonella typhi, of more than 3 months duration. This study suggests the possibility of applying this new polymer to manufacture drainage catheters that resist catheter-induced infection, by delivering antibiotics for a longer period of more than 1 month.

The authors present two cases of arteriovenous malformation (AVM) involving the visual pathway following linear accelerator (LINAC) stereotactic radiosurgery. Both patients were treated with 18 Gy (marginal dose, 70-80% isodose line, 3 isocenter) delivered to the malformed vascular mass involving the optic tract on the right side. For both patients, however, less than 8 Gy were irradiated onto the ipsilateral optic chiasm and optic nerve, and 4.5 Gy were irradiated onto the contralateral optic nerve (20% isodose line). On the five-year follow-up MRI scan and angiogram, the AVM was totally obliterated in one patient and the AVM was markedly decreased in size in the other patient. Their visual fields were well preserved and visual acuities were even improved for both patients. We report here with on two cases of AVM involving the visual pathway that were effectively and safely treated with 18 Gy using LINAC-based radiosurgery, and we also attempt to define the safe and effective radiation dosage for the patients with AVM involving visual apparatus.

The most common and neurologically important enthesopathy that is caused by inflammation of tendinous and ligamentous attatchments to bone is ossification of posterior longitudinal ligament (OPLL). The OPLL can occur at the posterior surface of the spinal vertebral bodies from the foramen magnum to the sacrum; however, the cervical portion of the vertebra is mainly affected. The cervical OPLL is originally thought to occur only in individuals of Japanese descent; however the advances in its diagnosis by using computed tomography and magnetic resonance imaging have led to more frequent identification of the disease in other Asians and whites as well. The cervical OPLL is a surgically treatable cause of myelopathy and various surgical approaches including anterior and posterior approach have been introduced. Although the indications of surgical treatment have been defined, the selection of the most effective operation remains controversial.

OBJECTIVE: This study is aimed whether bcl-xl could protect C4 cells from the cell death induced by serum deprivation. METHODS: The transient transfection of the bcl-xl gene was made with a LipofectAMINE reagent. An immunohistocytochemical assay and Western-blotting were performed to examine the bcl-xl transfection into the C4 cells. In order to analyze the effect of the bcl-xl transfection, the number of cells on the well plate were serially counted each day, for 5 days, from the 2nd to the 6th day after transfection. The number of GFP-positive cells in the defined fields, following serum deprivation, was counted using fluorescence microscopy, and the total number of viable cells, including transfected cells, were also assessed. RESULTS: Immunocytochemical staining showed positive cells in 52% of nestin staining, 60% of GFAP and 20% of MAP-2. The number of cells decreased after transfection using the LipofectAMINE in the serum free medium (p<0.001). Western blotting using an anti-human bcl-xl antibodies showed that bcl-xl was expressed in both the non-transfected and bcl-xl transfected C4 cells. Cell death in the C4 cells, and the number of cells, were serially monitored each day for 5 days. In the bcl-xl transfected cells, the cell death induced by serum deprivation was significantly inhibited and delayed compared to that in the control cells (p<0.001). CONCLUSION: It is suggested that the bcl-xl transfected human neural progenitor cells might improve the survival of the grafted cells, and may be an alternative source of cells for neural transplantation in degenerative diseases.

OBJECTIVE: The purpose of this study is to identify risk factors for subarachnoid hemorrhage(SAH) in Korea. METHODS: The clinical record and environmental data of 250 patients who had admitted our hospital between September 2001 and May 2003 were reviewed retrospectively by the neurosurgical nursing practitioners. RESULTS: In this study, the peak age for presentation with ruptured intracranial aneurysm was around 5th decade which is most active period of his or her life. The peak time of aneurysm rupture was from 6 to 12 A.M.(34.8%) and the onset of SAH occurred the most frequently at work(30.4%). The prevalence of hypertension in SAH patients was 42.8%, That of cigarette smoking in men and in women were 81.7% and 15.8% respectively. Hypertension was significantly corrected with the amount of hemorrhage based on Fisher Grading system(P<0.05). The consumption of smoking and the amount of hemorrhage was closely correlated also(P<0.05). CONCLUSION: Hypertension and cigarette smoking may be closely related to aneurysmal SAH. Undoubtedly, they are significantly related to massive, fatal SAH with poor neurologic condition. To prevent reduce aneurysmal SAH, cessation of smoking, anti-hypertensive medication and stress control are most important basic step in promotion of public health.
