Groups of 25 Workmen's Compensation Board patients (WCP group) and 25 non-Workmen's Compensation Board patients (NWCP group) hospitalized because of low back pain were compared. The WCP group had a significantly higher male:female ratio, incidence of sudden onset and precipitating factors, and prevalence of weakness, decreased reflexes and sensory loss. Surgical treatment and multiple operations were significantly more frequent in the WCP group, as was complete long-term relief or worsening after operation. Adequate partial relief was significantly more frequent in the NWCP group. The differences suggest more severe conditions in the workmen. Prevalence of psychological factors was not significantly different, although a trend was observed for this to be greater in the WCP group.

Three cases of tethered cord syndrome are presented with reference of reported literatures. This syndrome is usually associated with spina bifida occulta and cutaneous manifestation such as subcutaneous tumor, skin dimple, hairy patch, and neavus. Presented symptoms are various progressive neurological deficits involving weakness and/or sensory disturbance of lower limbs, bowel and/or bladder dysfunction, leg and/or low back pain, and orthopedic pathological conditions such as scoliosis and/or foot deformities. Properly performed myelography is the only method of preoperative confirmation of this syndrome. As the surgical release of the tethered spinal cord is effective for these various symptoms except for foot deformity, early investigation and early surgery are recommended.

The protrusion of cervical intervertebral discs was divided into three pathological entities by Spurling; soft disc, hard disc and spondylosis. We applied these concept to the dorsal intervertebral disc disease and treated two cases of thoracic spondylosis. Case 1. A 41-year-old male entered the hospital because of the gradual progression of weakness of both legs of two months' duration. Since ten days before admission he had not had an errection and had not been to able to walk and micturate. He also complained of paresthesia radiating down the abdomen into both legs. There were no visceral complaints. Neurological examination revealed severe weakness of both legs with bilateral impairment of deep sensations and hypalgesia up to the level of T6. Reflexes in both legs were hyperactive with sustained clonus. Plantar responses were extensor bilaterally. Though plain X-rays showed no changes, tomography revealed a calcified intervertebral spur formation at the T5-6 interspace. A myelogram showed a complete block of the contrast medium at the level of the upper part of T6. The patient underwent a complete laminectomy from T3 through T6 and extradural anterior decompression with the removal of the calcified disc at the T5-6 interspace using an air drill. Postoperatively, he demonstrated an immediate improvement in sensation and a gradual recovery in motor power. At his follow-up examination 14 months after surgery he could walk without assistance. Case 2. A 47-year-old dwarfish woman (130 cm) with a low back pain and difficulty in walking for a few years duration was admitted. A few months before admission she felt pain at her left lateral abdomen. There was weakness of both legs, greater in the left. Reflexes in her left lower extremity were hyperactive with sustained clonus. Plantar responces were flexor bilaterally. Palin X-rays showed scoliosis of thoracic spine with the top at T7 level and calcified intervertebral masses at T10-11, T11-12 and T12-L1, extending into the canal that were confirmed more clearly by tomography. Myelography by a cisternal puncture disclosed a complete block at the level of T10. The patient underwent total laminectomy of T9 through L2 and extradural anterior decompression with the removal of calcified discs. At her follow-up examination 12 months after surgery she could walk for herself with some residual neurological signs, minimal weakness in the right leg and hypesthesia up to the level of T12 in the left. We have discussed the incidental, related diagnostic and operative problems of this disease.

To determine the risk factors of the subjective symptoms experienced by chain saw workers, we surveyed 206 forestry workers using this device in their work. The strength of the relationship between their symptoms and such potential risk factors as occupational, behavioral, and physical factors was evaluated by a multiple logistic regression model. It was found that many years of chain saw operation, and numerous hours of chain saw operation per day, increased the risk of white finger, numbness of hands and arms, chillness of hands and arms and difficulty in joint movement, indicating that these symptoms were closely related to vibration exposure. Many years of forestry work before chain saw work also increased the risk of joint pain, suggesting that bone and joint disorders are related to heavy manual work not using a chain saw. A second job involving manual labor increased the risk of weakness in the arms, stiffness of the shoulders, and lumbago. Infrequent bathing was associated with increased risk of pain in hands and arms and lumbago. Older workers had a higher prevalence of stomach discomfort. No risk factor was found to significantly increase the risk of easy fatigability, forgetfulness and sleep disorder. It was found that not only exposure to vibration but also other factors contributed to the prevalence of pain in hands and arms, joint pain, weakness in arms, stiffness of shoulder, and lumbago. Second job and infrequent bathing appeared to be related to the occurrence of certain subjective symptoms. These contributory factors should be taken into account when evaluating subjective symptoms encountered in field studies of forestry workers.

Bajiaolian (Dysosma pleianthum), one species in the Mayapple family, has been widely used as a general remedy and for the treatment of snake bite, weakness, condyloma accuminata, lymphadenopathy and tumours in China for thousands of years. However, the textbooks of traditional Chinese medicine mention little about the toxicity of Bajiaolian. Within 1 year, the authors saw five people who manifested nausea, vomiting, diarrhoea, abdominal pain, thrombocytopenia, leucopenia, abnormal liver function tests, sensory ataxia, altered consciousness and persistant peripheral tingling or numbness after drinking infusions made with Bajiaolian. The herb was recommended by either traditional Chinese medical doctors or herbal pharmacies for postpartum recovery and treatment of a neck mass, hepatoma, lumbago and dysmenorrhoea. Podophyllotoxin is one of the main ingredients of the Bajiaolian root. The clinical manifestations observed in our patients were consistent with podophyllum intoxication. Podophyllotoxin intoxication usually results from the accidental ingestion or topical application of podophyllum resin. However, these cases of Bajiaolian intoxication were iatrogenic and results from 'therapeutic doses' of Bajiaolian cited in the textbooks of traditional Chinese medicine.

Research regarding the effect of exercise on chronic benign axial pain is reviewed. Both chronic low back pain (LBP) and chronic neck pain are associated with weakness of the trunk and neck musculature; however, it is unknown whether weakness is a cause or effect. The relationship between incoordination of the neck or trunk musculature and chronic pain is unclear. Exercise is associated with improved strength and endurance and decreased pain in subjects with LBP but the literature is very sparse with respect to chronic neck pain. Range-of-motion is also diminished in those with LBP and improves with exercise, and is associated with abatement in symptoms. No evidence could be found regarding the effect of exercise on segmental motion. Exercise is also associated with improved function, however the mechanism whereby either pain report or function improves is unclear. A greater understanding of the role of exercise will require more specific studies of strength, coordination, motion, function, and pain.

In this contribution the clinical features of eleven patients suffering from a neurinoma in the cauda equina and around the conus medullaris are analysed. Because of the relative mobility of the roots and the wide space in the spinal canal, tumours arising in the cauda equina or around the conus medullaris can become larger than any other spinal tumours. Lumbago was the predominant symptom as the initial complaint. Nocturnal pain relieved by walking was noticed in one patient. Two cases showed spontaneous remission and relapse. Multiple tumours were found in 6 cases (55%). Macroscopic cyst formation was found in 5 cases (45%). Among the eleven patients, total removal of the tumour, including the involved root, was performed in ten. The numbers of the resected nerve roots were one root in 6 cases, two roots in 2, and three roots in 2. Only one patient showed postoperative slight weakness of the leg.

This study investigated whether paraspinal muscle wasting occurs in association with chronic low back pain (LBP). Cross-sectional areas (CSA) of spinal and paraspinal structures were measured radiographically, at the level of L4, in 43 patients with recent and 44 with chronic LBP. Crude anthropometry demonstrated no differences between the groups with regard to L4 and paraspinal and psoas muscle CSAs, but inter-individual differences were large. Since body weight correlated significantly with L4 CSA this dimension was used as an 'internal standard' and further inter-individual comparisons were made using paraspinal: L4 and psoas: L4 (i.e. muscle to bone) CSA ratios. Muscle assessments made in this 'relative' fashion revealed significant reductions in paraspinal and psoas dimensions in patients with chronic compared to recent onset LBP. These changes could cause paraspinal and psoas muscle weakness and thereby predispose to spinal instability and progressive dysfunction.

Vertebro-sexual correlations were studied in 120 men with low back pain. The weakness of sexual constitution in patients with radicular syndromes indicates a correlation between vertebrogenic and sexual insufficiency. Sexual disorders in this group (27% of cases) are, probably, the result of strongly pronounced asthenia. High occurrence of sexual disorders (41%) in the group of patients with reflex syndromes depends on the main vascular mechanisms.

A rare case of intramedullary holocord astrocytoma extending from the medulla oblongata to the conus medullaris is reported. A 27-year-old male who had been suffering from nuchalgia for a few years was admitted to our department because of lumbago and gait disturbance. Neurological examination revealed sensory disturbances in various locations, weakness of the right lower extremity, mild swallowing disturbance, and bowel and bladder difficulties. Magnetic resonance (MR) images and myelograms showed a long cystic lesion extending from the medulla oblongata to the thoracolumbar spinal cord. Gadolinium-diethylenetriaminepenta-acetic acid (Gd-DTPA)-enhanced images detected a solid tumor located at the Th6-7 level. Two syrinx-subarachnoid shunts were placed at the upper cervical and Th12 levels. The solid neoplasm at the Th7 level was partially resected and histologically diagnosed as astrocytoma. Differentiation between cystic lesions and solid masses in the spinal cord is difficult. The usefulness of Gd-DTPA-enhanced MR imaging in the diagnosis of holocord tumor and the pathogenesis of secondary syringomyelia are discussed.
