Thirteen paraplegias after decompression have been treated in the 5 centres of Lyons, Geneva, Mulhouse, Basel and Strasbourg. All these cases are somehow comparable: 12 males, 1 female, skilled and well-trained divers are involved from 27 to 50 years. Submersion between 30 and 42 metres, during 15 to 30 minutes. Ascension with or without decompression stops. Beginning with sudden posterior thoracic, 4 feeling sick, 2 becoming briedly unconscious, paralysis after a while (until 1 hour). All have received hyperbaric oxygenation (from 1 to 5 hours later), with an improvement for 10. Neurological findings. 5 tetraplegics, 7 para-(5 with Brown-Sequard), and one LI. Quickly, the tetraplegics improved to a thoracic level. In two cases, paraplegia remained complete at thoracic level. The others had a better evolution; the paralysis improved slowly, with marked spasticity, impaired sensation did not improve to such an extent, often localised at a lower level, with sexual impotence. Micturitions became normal but with often urine leakages. This rather favourable evolution allowed 11 to go back to work.

Based on the angiographic findings of the injured spinal cord percutaneous embolisation of Adamkiewicz's artery was carried out to control intractable spasticity in ten cases of late stage spinal cord paralysis. The purpose of this procedure was to interrupt the reflex arcs of the lower extremities by decreasing the blood supply to the lumbar enlargement. Results were excellent in two cases, good in five and poor in three. Major effects were found in adduction and flexion spasticity of the hip joints and bladder function was always preserved in these patients. It is speculated that occlusion of Adamkiewicz's artery mainly affected the lower thoracic and the upper lumbar segments. Anastomosis between the anterior spinal artery and the two posterior spinal arteries might have provided sufficient collateral blood circulation to the conus level. It is emphasised that the percutaneous embolisation of Adamkiewicz's artery reduced the intractable spasticity of the lower extremities without changes in the voiding function of the automatic bladder.

The etiological factors in 1503 patients with cerebral palsy seen since 1947 are listed. Prematurity was the most prominent factor, being present in 27.8 per cent of cases. 38.5 per cent of the causes were prenatal in origin, 46.3 per cent natal, and 15.2 per cent postnatal. Since 1947, the number of patients seen rose to a maximum in the 1950s and has fallen since. A steadily increasing percentage of the patient population has been children with spasticity, especially paraplegia and quadriplegia. Although small, the atonic group has shown a marked increase, from 0.8 per cent in the 1950s to 3.4 per cent in the 1970s. There has been a dramatic decrease in the incidence of athetosis, from 38 per cent to about 3 per cent, and a slight decrease in the rigidities. The incidence of some of the etiological factors has increased, such as hydrocephalus, prematurity, trauma and multiple birth. There has been a striking decrease in the incidence of erythroblastosis as a factor, which dropped to nil in the 1970s. There have been lesser decreases in encephalitis, dystocia and idiopathic factors.

Fifty consecutive spinal injury patients who underwent simultaneous EMG of the peri-urethral and perianal striated muscles along with cystometrogram on a multiple channel recorder are analysed. Bladder filling, voiding and also influence of spasticity on the EMG activity of both perianal and periurethral striated muscles were compared. Periurethral striated EMG along with CMG has a better diagnostic value (95 per cent) as compared to perianal EMG-CMG which was diagnostic in 72 per cent patients.

The neurotoxicity mediated by alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), an agonist for glutamate receptors, was investigated by infusing adult rats with this agent intrathecally for either a short term (2 hours) or a long term (7 days) using a mechanical pump or a mini-osmotic pump, respectively. In the short-term infusion group, spasticity of the hindlimbs developed during infusion at 0.5 nmol/h or more of AMPA, tremors at 50 nmol/h or more, and flaccidity at 65 nmol/h or more. One day later, flaccid paralysis of the hindlimbs and urinary incontinence were observed in the rats that received 50 nmol/h (total dose: 100 nmol) or more of AMPA. These symptoms were thought to be permanent. On the other hand, in the long-term infusion group, behavioral changes were apparent only after second postoperative day, when rats displayed hindlimb palsy or urinary incontinence. Behavioral deficits became progressively severe, and rats usually displayed both hindlimb paraplegia and urinary incontinence by the 7th postoperative day. These progressive behavioral deficits were induced in a dose-dependent manner in rats that received AMPA at doses greater than 0.1 nmol/h. Gliosis with neuronal loss involving the partial (lumbar segments) and whole (sacral segments) gray matter of the spinal cord was induced in rats that received AMPA at doses greater than 50 nmol/h in the short-term infusion group and greater than 0.1 nmol/h in the long-term infusion group.(ABSTRACT TRUNCATED AT 250 WORDS)

Out of a regional traumatic spinal cord injury population consisting of 379 individuals, 353 (93.1%) participated in the present study. Subjects were individually interviewed using semi-structured protocols. In addition, previous medical records were available for over 96% of subjects, and were used in all these cases to minimise recall bias. Cause of injury, prevalence of present medical symptoms and occurrence of medical complications in the post-acute, post-discharge phase were recorded. Neurological classification was verified by physical examination according to ASIA/IMSOP standards. Many subjects had experienced complications since discharge from initial hospitalisation, especially urinary tract infections, decubitus ulcers, urolithiasis, and neurological deterioration. Prevalence of medical symptoms was also high. More than 41% of subjects with spastic paralysis reported excessive spasticity to be associated with additional functional impairment and/or pain. Almost two-thirds of subjects reported significant pain, with a predominance of neurogenic-type pain. Bladder and bowel dysfunction were each rated by nearly 41% of subjects as a moderate to severe life problem. As expected, sexual dysfunction was also commonly reported. Prevalence of reported symptoms by general systems review was high, particularly fatigue, constipation, ankle oedema, joint and muscle problems, and disturbed sleep. However, lack of adequate normative data precludes comparison with the general population. The frequent occurrence of reported medical problems and complications support advocacy of comprehensive, life-long care for SCI patients. The commonly reported problems of neurogenic pain and neurological deterioration, in particular, require more attention, as these symptoms are not seldom ominous, either by virtue of their impact on quality of life, or because of underlying pathology.

In twenty-five SCI subjects, antispasticity effects of three putative antispasticity agents [clonidine (an alpha-2 noradrenergic agonist), cyproheptadine (a 5-HT2 antagonist) and baclofen (a GABA-B agonist)] were tested in terms of changes in leg tone as graded by the Ashworth scale (AS), in terms of the vibratory inhibition of the H-reflex (VII) and in terms of the ability of the knee to swing passively in the pendulum test as quantified by video motion analysis. When compared to the no drug period, all three drug treatments showed an antispasticity effect on the AS, the VII and the amplitude of the first swing and the relaxation index of the pendulum test, p. < 0001. Surprisingly, cyproheptadine and baclofen produced a greater reduction in the VII than clonidine, p. < 01. The amplitude of the first swing in the pendulum test correlated well with the AS, r = .88, and the antispasticity effects of the drugs produced improvements in both measures, a reduced AS and increased amplitude of knee swing in the pendulum test. Therefore, video motion analysis of the pendulum test is as valid a measure of spasticity as the Ashworth scale and is not limited by subjectivity of the examiner.

Two cases of anterior spinal hernia are presented. The medical literature is reviewed, the syndrome characterised, and its cause and treatment discussed. The patient is typically middle aged with a history of stepwise slowly progressive mid-thoracic anterior hemicord syndrome manifesting as hemianalgesia below the affected segment, followed by contralateral lower limb spasticity that develops into an asymmetric paraparesis with sparing of dorsal column sensation. Radiological investigation demonstrates an enlarged dorsal arachnoid space in association with an apparently focally narrowed thoracic cord, kinked towards the anterior dura. At operation the cord is found to be prolapsed into an anterolateral dural diverticulum. The most likely cause of this syndrome is anterior spinal artery segmental branch ischaemia, in a cord chronically incarcerated in a congenital anterior meningocele. This readily treatable condition should be considered in all cases of thoracic cord dysfunction and surgical repair effected early to prevent stepwise progression to paraplegia.

To eliminate severe leg spasms of 15 quadriplegics, 0.3 ml 10% phenol-glycerin was injected into the subarachnoid space at the T12/L1 interspace. The effectiveness for leg spasm was evaluated by the Penn spasticity and Ashworth rigidity scales. Three patients remained completely flaccid; however three had slight, six had moderate and three had complete recurrence of spasms in a follow up period of observation for 1 to 22 (average 13) months. The result of selective intrathecal phenol block was significantly valuable, improving the activities of daily living (ADL) of quadriplegic patients. There were no systemic side effects nor disturbance of bladder, bowel or sexual functions.

Neurolathyrism is a form of spastic paraparesis caused by the neuroexcitatory amino acid 3-N-oxalyl-L-2,3-diaminopropanoic acid (beta-ODAP) present in the seeds and foliage of Lathyrus sativus. The disease is irreversible and usually nonprogressive. Tolperisone HCl, a centrally acting muscle relaxant, has been shown to reduce significantly the spasticity in neurolathyrism patients. Sporadic occurrence of HTLV-1 infection (0.9%) and of osteolathyrism was found among the neurolathyrism patients. Osteolathyrism is linked to the consumption of the green shoots of Lathyrus sativus.
