Lysis of epidural adhesion has been done in patients with refractory lumbar radiculopathies. Cauda equina syndrome is a rare complication of epidural block. We report on a case of cauda equina syndrome following epidural adhesiolysis in a patient with spinal stenosis. The patient complained of numbness of the perineum, weakness of the left leg, an inability to void and fecal incontinence. She was treated with medication, bladder training and physical therapy, and finally recovered 1 month after the procedure without any sequelae. We suggest that the causative factors are osmotic damage produced by the subarachnoid injection of large doses of hypertonic saline and temporary neural compression due to spinal stenosis.

Intracranial pial arteriovenous fistulas (AVFs) are rare vascular lesions of the brain. These lesions consist of one or more arterial connection to a single venous channel without true intervening nidus. A 24-year-old woman visited to our hospital because of headache, vomiting, dizziness and memory disturbance that persisted for three days. She complained several times of drop attack because of sudden weakness on both leg. Cerebral angiograms demonstrated a giant venous aneurysm on right frontal lobe beyond the genu of corpus callosum, multiple varices on both frontal lobes fed by azygos anterior cerebral artery, and markedly dilated draining vein into superior sagittal sinus, suggesting single channel pial AVF with multiple varices. Transarterial coil embolization of giant aneurysm and fistulous portion resulted in complete disappearance of pial AVF without complication.

A 73-year-old male presented with a rare dorsally sequestrated lumbar disc herniation manifesting as severe radiating pain in both leg, progressively worsening weakness in both lower extremities, and urinary incontinence, suggesting cauda equina syndrome. Magnetic resonance imaging suggested the sequestrated disc fragment located in the extradural space at the L4-L5 level had surrounded and compressed the dural sac from the lateral to dorsal sides. A bilateral decompressive laminectomy was performed under an operating microscope. A large extruded disc was found to have migrated from the ventral aspect, around the thecal sac, and into the dorsal aspect, which compressed the sac to the right. After removal of the disc fragment, his sciatica was relieved and the patient felt strength of lower extremity improved.

Alcoholic polyneuropathy is a disorder of the peripheral nervous system that interferes with sensory, motor, and autonomic nerve function. This study was to report the effect of Oriental medical treatment on a patient with alcoholic polyneuropathy. Conservative Oriental medical treatment was done to a man of 84 years who was diagnosed as a alcoholic polyneuropathy and suffered from both distal dominant leg weakness & symmetrical paresthesia and ataxic gait. The changes of symptoms, reflexes and sensory test were checked by Toronto Clinical Neuropathy Scoring System(TCNSS). Reflexes, motor and sensory impairments were improved after the Oriental medical treatment. I reported good effects of Oriental medical treatment on alcoholic polyneuropathy. Oriental medical treatment can be helpful to improve the symptoms of alcoholic polyneuropathy.

Purpose: The study was done to identify the perceived health status of elderly women and men, and define the difference between the two groups. Method: The subjects of this study were 209 elderly people over 60 years living in urban areas. The data was collected through personal interviews using questionnaires from September to October 2002. Data was categorized by content analysis and then data was analyzed with the SPSS program by frequency and Chi-square tests. Result: Elderly women complained of types of pain(leg pain, arthritis, lumbago, headache) more than elderly men. Elderly men complained about decreased levels of activities such as walking and general weakness. Elderly men and women have discomforts in daily living such as walking and doing household chores. First, elderly men and women want good health and improvement of health status. Second, women want happiness for their offspring, but men want to improve the government and the laws. Conclusion: Elderly women want relief from pain, but elderly men want an increased level of activity. The findings of this study give useful information to conduct health education and care for elderly women.

A 45-year-old female visited our clinic due to sudden right leg weakness and sensory loss. Brain and spinal cord magnetic resonance imaging showed widespread cavernous malformations. Cavernous malformation in L1 spine area was accompanied by a subacute stage hematoma with perilesional edema. Sensory loss subsided after corticosteroid therapy. Usually, neurologic deficit by spinal cavernous malformation appears more chronically in the adults compared to children. Treatment options are difficult to establish in a case with multiple cavernous malformations. Identifying hemorrhagic lesions by extensive neuroimaging evaluation could be helpful to select the treatment target for cavernous malformation.

Migration of a disc fragment to the posterior epidural space is rare, especially in the thoracic spine. Only four such cases of posterior epidural migration of thoracic disc fragments have been reported. The authors report a case of 66-year-old man who presented with back pain and right leg weakness due to posterior epidural migration of thoracic disc fragment. The patient was successfully treated by laminectomy and partial facetectomy with disc removal.

The conventional actuators with the speed reducer had weakness in supporting the weight of the body and leg itself. To overcome this, a new four bar link mechanism actuated by the ball screw was proposed. Using this, we developed a new type of 10 D.O.F biped robot. The dynamics model of the biped robot is investigated in this paper. In the modeling process, the robot dynamics are expressed in the joint coordinates using the Euler-Lagrange equation. Then, they are converted in to the sliding joint coordinates, and joint torques are expressed in the force along the sliding direction of the ball screw. To test modeling of the robot, a computer simulation was performed.

In this study, the axial ODSCC occurrence of domestic OPR 1000 steam generator tube was caused by the tube weakness and the sludge accumulation in the secondary side of steam generator. Inconel 600 HTMA used as tube material is related to most of tube leakage accidents in the world and also these ODSCCs were detected mainly at the 5th TSP(Tube Support Plate) to the 8th TSP of hot leg side. These elevations(5th TSP to 8th TSP) pave the way for the sludge accumulation. As a result of EC(Eddy Current) Bobbin and RPC data analysis, ODSCCs were occurred at contact points of tube and tube support plate. The more accumulated sludge, the higher occurrence frequency of ODSCC.

The diagnosis of peripheral neuropathy had been performed by electrophysiologic studies and neurologic examination. However, Magnetic Resonance Imaging (MRI) has recently been proposed as a supplementary tool for its diagnosis. A 55-year-old woman presented with back pain and painful proximal weakness of the right leg. Neurologic examination and electrophysiologic studies suggested an upper lumbar plexopathy. MRI disclosed the signal change in lumbar plexus with the atrophy of the innervating muscles. We report a patient with idiopathic lumbar plexopathy confirmed by MRI.
