  • Glaucoma is one of the leading causes of blindness worldwide and is characterized by degeneration of the optic nerve. Elevated intraocular pressure (IOP) is the major contributing factor to optic nerve damage. However, some patients develop glaucoma even with normal IOP. Other factors, including age, race, myopia, and nutrition, can affect glaucoma risk. Dietary fat intake and serum fatty acid composition are closely related with the fatty acid profile of the retina and thus can modulate glaucoma risk. In this study, we collected serum samples from 34 glaucoma patients (26 primary open angle glaucoma (POAG) and 8 normal tension glaucoma (NTG)) and 45 healthy controls and analyzed their serum phospholipid fatty acid concentrations. The results show that the ratio of oleic acid to stearic acid (OA/SA), which is an indicator of stearoyl-CoA desaturase activity, was higher in POAG patients when compared to normal controls. The ratio of eicosapentaenoic acid to arachidonic acid (EPA/AA), which is an indirect marker of eicosanoid biosynthesis, was also higher in glaucoma patients (p=0.048). These results imply that dietary fatty acid intake and serum fatty acid profile can influence glaucoma risk. Additional study is necessary to identify the relationship between fatty acids and glaucoma.

  • Objectives: Long-term facial paralysis results in degeneration of the distal nerve segment and atrophy of the supplied muscles. Options for these patients include free muscle transfer, temporalis myoplasty, and botulinum toxin injections for smile reanimation. In this study we aimed to evaluate the subjective and objective outcomes of these procedures. Materials and Methods: In our study, we retrospectively analyzed smile symmetry in patients with facial palsy (n=8) who underwent facial reanimation procedures. Results: Subjective analysis showed high satisfaction in seven out of eight patients. Objective analysis showed statistically significant improvement postoperatively in both vertical and horizontal smile symmetry at rest and during maximum smile (P<0.001). Conclusion: Choosing the ideal procedure for the patients is the most critical aspect for facial reanimation. Though free muscle transfer is considered gold standard procedure, temporalis myoplasty also gives satisfactory results. Residual synkinesis which can lead to disturbing aesthetic deformity can be effectively treated with botulinum toxin.

  • Objectives : The purpose of this study is to find out the characteristics of intervertebral disc changes and relative factors of the spondylolisthesis patients in fifties by type of spondylolisthesis. Methods : We investigated 69 cases of patients who visited one Korean traditional medicine hospital and were diagnosed as spondylolisthesis on L-spine X-ray and L-spine magnetic resonance imaging(MRI). We selected 37 lytic spondylolisthesis patients and 32 degenerative spondylolisthesis patients. We analysed the relativity between the numbers of changed discs, types of changed disc, locations of nerve compression and types of spondylolisthesis. Results : 1. The number of changed discs increase in lytic type, but there is no statistically significant difference. 2. Bulging disc is the dominant type of disc change. There is no significant difference between two types. 3. Both foraminal type was shown dominantly in lytic spondylolisthesis, diffuse type in degenerative spondylolisthesis by the analysis of the location of the nerve compression. But the symptoms of patients and dermatome did not match in most of the cases. Conculsions : The direction of nerve compression is different while the disc changing aspects are similar in both types. In several spondylolisthesis patients in fifties, symptoms of patient are related to degeneration of vertebrae, not to the type of spondylolisthesis.

  • Hereditary neuropathy with liability to pressure palsy (HNPP) is a rare neurological genetic disease caused by deletion of the peripheral myelin protein 22 gene and presents in childhood or young adulthood. We report four cases of HNPP with typical and rare presentations, reflecting the broad clinical spectrum of this disease. Two patients presented with mononeuropathies that are frequently observed in HNPP; the remaining two presented with bilateral neuropathy or mononeuropathy anatomically present in the deep layer. This reflects the broad clinical presentation of HNPP, and clinicians should differentiate these conditions in young patients with monoparesis or bilateral paresis. Although HNPP is currently untreatable, early diagnosis in the emergency department can lead to early detection, eventually resulting in less provocation and recurrence which may cause early motor nerve degeneration.

  • Neurosarcoma is relatively rare, but is seen frequently in association with stigmata of neurofibromatosis ie., Cafe au lait pigmentation and cutaneous neurofibromatosis. Both advanced age and association with neurofibromatosis increase the likelihood of malignant degeneration to neurosarcoma. It also may be dumb bell-shaped with intraspinal extension. Thoracic meningocele is rare and represents a protrusion of the dural sac through an abnormally large or malformed intervertebral foramen. The patient is usually asymptomatic, with evidence of paravertebral mass on the chest rentgenogram. In one operation we removed a "Dumb-bell" neurosarcoma and intrathoracic meningocele in a 52 year old woman using a cervical laminectomy with a trap-door incision. She was discharged at 17 days after the operation with a sequelae of excision of nerve roots C8 and T1. Postoperative radiation therapy was performed during the follow-up period.up period.

  • Achalasia is the disease of nonorganic obstruction of the cardia associated with dilatation of the esophagus, and of unknown etiology characterized by failure of relaxation of the inferior esophageal sphincter and lack of normal peristalsis in the body of the esophagus. This disorder is primarily one of neuromuscular dysfunction, most probably due to a central nervous system lesion with consequent nerve, ganglion and muscle degeneration. The characteristic symptoms are dysphagia, regurgitation and epigastric pain etc. We have experienced a case of Achalasia in 43 aged female with good results by daily mercury bougienage.

  • Degenerative disc disease has traditionally been thought of as low back pain caused by changes in the nucleus pulposus and annulus fibrous, in recent studies, however, changes in the upper and lower endplates cause degeneration of the disc, resulting in mechanical pressure, inflammatory reactions and low back pain. Recently, the bone marrow of the vertebral body-endplate-nucleus pulposus and annulus fibrous were considered as a single unit, and the relationship was explained. Once the endplate is damaged, it eventually aggravates the degeneration of the bone marrow, nucleus pulposus, and annulus fibrosus. In this process, the compression force of the annulus fibrosus increases, and an inflammatory reaction occurs due to inflammatory mediators. Hence, the sinuvertebral nerves and the basivertebral nerves are stimulated to cause back pain. If these changes become chronic, degenerative changes such as Modic changes occur in the bone marrow in the vertebrae. Finally, in the case of degenerative intervertebral disc disease, the bone marrow of the vertebral body-endplate-nucleus pulposus and annulus fibrous need to be considered as a single unit. Therefore, when treating patients with chronic low back pain, it is necessary to consider the changes in the nucleus pulposus and annulus fibrosus and a lesion of the endplate.

  • Ancient schwannoma is a rare variant of schwannoma and a slow growing benign tumor associated with degeneration that may be diagnosed as a malignant tumor, because it presents with a large size and an inhomogeneous signal intensity. The main differential diagnosis of plexiform soft tissue tumor includes plexiform neurofibroma, malignant peripheral nerve sheath tumor (MPNST). In this case, we describe the MRI findings in a case of ancient schwannoma involving left thigh of a 63-year-old woman mimicking a plexiform MPNST. The tumor appeared as an inhomogeneous signal intensity and multinodular appearance, causing misdiagnosis as a plexiform MPNST.

  • Objectives : In the assessment of the lumbar spine by magnetic resonance imaging (hereinafter, "MRI"), changes in the paraspinal muscles are overlooked. The purpose of our study is to examine the correlation between the multifidus muscle atrophy on MRI findings and the clinical findings in low back pain (hereinafter, "LBP") patients. Methods : The retrospective study on 38 LBP patients, presenting either with or without associated leg pains, was undertaken. The MRI findings on the patients were visually analysed to find out a lumbar multifidus muscle atrophy, disc herniation, disc degeneration, spinal stenosis and nerve root compressions. The clinical history in each case was obtained from their case notes and pain drawing charts. Results : The lumbar multifidus muscle atrophy has occurred from more than 80% of the patients with LBP. Most of lumbar multifidus muscle atrophies have increased from lower level of lumbar spine. It was bilateral in the majority of the cases. In addition, multifidus muscle atrophy was correlated to the patient's age, disc degenerations and spinal stenosis. On the contrary, gender, the duration of LBP, referred leg pain, disc herniation and nerve root compressions had no relevance to multifidus muscle atrophies. Therefore, when assessing the MRIs of the lumbar spine, we should have more attetion on multifidus muscle, because it has lot's of information about spinal neuropathy problems. Conclusions : Therefore, the examination of multifidus muscle atrophies should be considered when assessing the MRIs of the lumbar spine. In addition, it helps to evaluate and plan the treatment modalities of LBP. Moreover, it prevents from LBP by discovering the importance between the multifidus muscle and the spine stabilization exercise.

  • Objectives: Previous reports have shown that Bogijetong-Tang (BJT) is effective in peripheral neuropathy induced by taxol and crush injury. In this study, we researched the effects of BJT on diabetic neuropathy induced by STZ in the mouse. Methods: We performed both in vitro and in vivo experiments to verify the effects of BJT on diabetic neuropathy induced by STZ in mice. Changes in axonal recovery were observed with immunofluorescence staining using NF-200, Hoechst33258, $S100{\beta}$, caspase 3 and anti-cdc2. Proliferation and degeneration of Schwann cells were investigated by immunofluorescence staining and western blot analyses. Results: BJT showed considerable effects on neurite outgrowth and axonal regeneration in diabetic neuropathy. BJT contributed to the creation of NF-200, GAP-43, Cdc2, phospho-vimentin, ${\beta}1$, active ${\beta}1$, ${\beta}3$ integrin, phospho-Erk1/2 protein. Conclusions: Through this study, we found that BJT is effective for enhanced axonal regeneration via dynamic regulation of regeneration-associated proteins. Therefore, BJT had a pharmaceutical property enhancing recovery of peripheral nerves induced by diabetic neuropathy and could be a candidate for drug development after more research.
