Objective : The authors characterize a syndrome of multiple neurogenic tumors in the spinal canal, which is unclassifiable by the current National Institute of Health[NIH] criteria for neurofibromatosis. Methods : We retrospectively examined cases in which two or more spinal neurogenic tumors were detected by magnetic resonance[MR] imaging and which had been pathologically confirmed. Eighteen patients were recruited between February 1986 and March 2002. According to NIH criteria, eight cases were neurofibromatosis type 1[NF1], four were type 2[NF2], and six were neither type 1 nor type 2 [Unclassifiable : UC]. The locations of lesions, clinical presentations, radiological findings, and pathological results with immunohistochemistry were reviewed. Results : In the case of NF2, three of four cases were intradural tumors. Pathological examinations revealed neurilemmomas in two of four NF2 and all of the UC cases. In the case of NF1, pathological examinations showed seven neurofibromas and one neurilemmoma. Concerning UC, the age at presentation was middle-aged to late [mean age 48.5, range 35 to 64], which contrasted with ordinary NF2, where patients tended to become symptomatic before 20years of age. The pathological examinations of UC cases revealed neurilemmoma similar to most of NF2 and the immunohistochemical study showed characteristic of NF1. Conclusion : Multiple neurogenic tumors in the spinal canal are an under-recognized disease entity. Further studies for genetic aberration in multiple spinal neurogenic tumors are needed.

Background: This study was designed to evaluate the clinical effectiveness of traditional Korean medicine treatment for lumbar spinal stenosis as assessed by radiological criteria. Methods: This was an observational study of 122 patients who were diagnosed with lumbar spinal stenosis and admitted to Jaseng Hospital between January 2016 and June 2017. They were analyzed according to sex, age, cause of disease, disease stage, length of admission, type of stenosis, morphological grade, and dural sac cross-sectional area. All patients were treated with traditional Korean medicine. Patients were assessed with the Numeric Rating Scale (NRS), Oswestry Disability Index (ODI) and EQ-5D before and after treatment. Results: Regarding the distribution of the factors analyzed, these were of note: more females than males (1:3.52); and highest proportions were age more than 70 years (37.70%), cause of lumbar spinal stenosis unknown (67.21%), and subacute stage (42.62%). Comparing before and after treatment, the NRS score for low back and pelvic pain decreased from $6.14{\pm}1.71$ to $4.28{\pm}1.91$ (p < 0.001), and the NRS score for radiating pain and numbness decreased from $6.27{\pm}1.61$ to $2.02{\pm}1.54$ (p < 0.001). ODI decreased from $46.86{\pm}19.40$ to $33.63{\pm}18.66$ (p < 0.001), and gait-related ODI decreased from $3.34{\pm}1.23$ to $2.80{\pm}1.11$ (p < 0.001). There were no statistically significant differences in improvement of the NRS, ODI, gait-related ODI, and EQ-5D for morphological grade and dural sac cross-sectional area. Conclusion: Traditional Korean medicine is effective treatment for patients with lumbar spinal stenosis. Even in patients with severe radiological findings, it is possible to reduce pain and improve quality of life.

Objective : The aim of the present study was to assess the safety and efficacy of the dynamic stabilization system in the treatment of degenerative spinal diseases. Methods : The study population included 20 consecutive patients (13 females, 7 males) with a mean age of $61{\pm}6.98$ years (range 46-70) who underwent decompression and dynamic stabilization with the Dynesys system between January 2005 and August 2006. The diagnoses included spinal stenosis with degenerative spondylolisthesis (9/20, 45%), degenerative spinal stenosis (5/20, 25%), adjacent segmental disease after fusion (3/20, 15%), spinal stenosis with degenerative scoliosis (2/20, 10%) and recurrent intervertebral lumbar disc herniation (1/20, 5%). All of the patients completed the visual analogue scale (VAS) and the Korean version of the Oswestry Disability Index (ODI). The following radiologic parameters were measured in all patients : global lordotic angles and segmental lordotic angles (stabilized segments, above and below adjacent segments). The range of motion (ROM) was then calculated. Results : The mean follow-up period was $27.25{\pm}5.16$ months (range 16-35 months), and 19 patients (95%) were available for follow-up. One patient had to have the implant removed. There were 30 stabilized segments in 19 patients. Monosegmental stabilization was performed in 9 patients (47.3%), 9 patients (47.3%) underwent two segmental stabilizations and one patient (5.3%) underwent three segmental stabilizations. The most frequently treated segment was L4-5 (15/30, 50%), followed by L3-4 (12/30, 40%) and L5-S1 (3/30, 10%). The VAS decreased from $8.55{\pm}1.21$ to $2.20{\pm}1.70$ (p<0.001), and the patients' mean score on the Korean version of the ODI improved from $79.58%{\pm}15.93%$ to $22.17%{\pm}17.24%$ (p<0.001). No statistically significant changes were seen on the ROM at the stabilized segments (p=0.502) and adjacent segments (above segments, p=0.453, below segments, p=0.062). There were no patients with implant failure. Conclusion : The results of this study show that the Dynesys system could preserve the motion of stabilized segments and provide clinical improvement in patients with degenerative spinal stenosis with instability. Thus, dynamic stabilization systems with adequate decompression may be an alternative surgical option to conventional fusion in selected patients.

Objective : Posterior lumbar interbody fusion (PLIF) is considered to have the best theoretical potential in promoting bony fusion of unstable vertebral segments by way of a load sharing effect of the anterior column. This study was undertaken to investigate the efficacy of PLIF with cages in chronic degenerative disc disease with Modic degeneration (changes of vertebral end plate). Methods : A total of 597 patients underwent a PLIF with threaded fusion cages (TFC) from 1993 to 2000. Three-hundred-fifty-one patients, who could be followed for more than 3 years, were enrolled in this study. Patients were grouped into 4 categories according to Modic classification (no degeneration : 259, type 1 : 26, type 2 : 55, type 3 : 11). Clinical and radiographic data were evaluated retrospectively. Results : The clinical success rate according to the Prolo's functional and economic outcome scale was 86% in patients without degeneration and 83% in patients with Modic degeneration. The clinical outcomes in each group were 88% in type 1, 84% in type 2, and 73% in type 3. The bony fusion rate was 97% in patients without degeneration and 83% in patients with Modic degeneration. The bony fusion rate in each group was 81% in type 1, 84% in type 2, and 55% in type 3. The clinical success and fusion rates were significantly lower in patients with type 3 degeneration. Conclusion : The PLIF with TFC has been found to be an effective procedure for lumbar spine fusion. But, the clinical outcome and bony fusion rates were significantly low in the patients with Modic type 3. The authors suggest that PLIF combined with pedicle screw fixation would be the better for them.

This study was conducted to elucidate the distribution of Aujeszky's disease viral nucleic acids and antigens in the central nervous system (CNS) of piglets. The first Korean isolate of Aujeszky's disease virus(ADV) that isolated from naturally infected piglets in Yang San, was inoculated into 32 day old piglets with $10^{5.9}TCID_{50}/ml$ through intranasal or intramuscular route. These piglets were sacrificed at every 24hrs for 8 days. The immunohistochemistry (IHC) was conducted to detect the viral antigens in paraffin-embedded tissue sections using avidin-biotin-peroxidase complex (ABC) method. The viral nucleic acids were detected by in situ hybridization (ISH) using ADV specific DNA probe labeled with digoxigenin. The ADV antigens were detected in reticuloendothelial cells of spleen, lymph nodes and tonsil, alveolar walls, leptomeningeal vascular walls, inflammatory foci of each organ, and nerve cells. The viral nucleic acids were detected in the spinal trigeminal nucleus and its tracts of the pons and medulla oblongata by the ISH technique. The pathways of AD viruses in CNS were determined by IHC and ISH. In the intranasally inoculated group, the viruses in nasal mucosa moved to medulla oblongata and pons through the trigeminal nerve. In case of intramuscullarly inoculated group, viruses moved to brain via lymphoid organs or spinal nerves from sciatic nerves.

Behcet's disease is a systemic disease affecting multiple organs including the central nervous system. Neuro-Behcet's disease was regarded as relatively rare, but thanks to the development of diagnostic tools, more and more cases are being reported. We are reporting a case of neuro-Behcet's disease in which the patient displayed paraparesis, dysarthria and involuntary tremor as neurologic symptoms. The patient's brain MRI showed cerebellar atrophy, and a spinal cord MRI failed to reveal any significant lesions. The patient experienced a couple of fever attacks during hospitalization, which were managed adequately by herbal medicines. Her main neurological symptoms such as paraparesis were, however, grossly unchanged at discharge.

Fifteen dogs with clinical signs of paraparesis, paraplegia and urinary dysfunction were referred to Veterinary Medical leaching Hospital, College of Veterinary Medicine, Konkuk University. According to physical and neurologic examination, survey radiograph and myelography, these patients were diagnosed as thoracolumbar intervertebral disc disease. All of them were treated with medical (prednisolone or carprofen, antibiotics), acupuncture (Ji Zhong, Bai Hui, Zhong Shu, Pang Guang Shu, Zu San Li, Huan Tiao) and physical therapy (hydrotherapy, thermotherapy, massage, manipulation, swimming). Of twelve patients were recovered of neurologic deficits within 21 days after the onset of treatment. However, three dogs were not resolved, which were found to have other spinal cord disease concomitantly. All of patients showed normal urination after treatment. Until 21 months after treatment, there were no recurrence in twelve patients. This study indicated that the conservative therapy could be effectively managed in paraparesis or paraplegia and urinary dysfunction which caused by intervertebral disc disease.

In controlling chronic intractable pains, the current therapeutic methods used are exercise, over the counter medication, cognitive-behavioral therapy, opioid medication, neural blockade, operation, etc., spinal cord stimulation being the last resort. Spinal cord stimulation was initiated when Shearly and others clinically tested the Gate control theory of Melzack and Wall. This had triggered the advancement of theoretic research on the mechanism and hardware necessary and has resulted in an accumulation of clinical experiences. This is known to be effective for treating sympathetic pain, arachnoiditis, failed back pain syndrome, radiculopathy, peripheral vascular disease, phantom limb syndrome, post-herpetic neuralgia, peripheral neuropathy, and angina pectoris. This report describes our experience in experimental spinal cord stimulation in patients with simultaneous post-herpetic neuralgia and herniated intervertebral disc. There wasn't any improvement in the post-herpetic neuralgia but the symptoms of a herniated intervertebral disc was much ameliorated. This was quite an unexpected result. The patient's back pain returned when the stimulation stopped.
