Patients with chronic tetraplegia are prone to develop unique clinical problems which require readmission to specialised centres where the health professionals are trained specifically to diagnose, and treat the diseases afflicting this group of patients. An appraisal of the readmission pattern of tetraplegic patients will provide the necessary data for planning allocation of beds for treatment of chronic tetraplegic patients. Hospital records of patients with tetraplegia readmitted to the Regional Spinal Injuries Centre, Southport, UK between 1 January 1994 and 31 December 1995 were analyzed to find out the number of tetraplegic patients who required readmission, reasons for readmission, duration of hospital stay, and mortality among patients readmitted. ⋯ As more patients with high cervical spinal cord injury survive the initial period of trauma, and as the life expectancy of tetraplegic patients increases, it is likely that greater numbers of tetraplegic patients will be requiring readmission to spinal injuries centre. Although it may be possible to prevent some of the complications of spinal cord injury and hence the need for a readmission, progress in medicine and rehabilitation technology will create additional demands for readmissions of chronic tetraplegic patients in order to implement the newer therapeutic strategies. Thus a change in the pattern of readmission of chronic tetraplegic patients is likely to be the future trend and this should be taken into account while making plans for providing the optimum care to chronic tetraplegic patients.

The effect of direct electrical stimulation on colinic transit and manometric recordings following spinal cord injury were assessed in five adult male cats. Intra-colonic catheters were surgically placed, stimulating electrodes were sutured to the colonic serosa and a laminectomy with spinal cord clamping at a T4 level was done to induce spinal cord injury (SCI). Twenty radiopaque markers were inserted through an intra-colonic catheter located 1 cm distal to the cecum and were monitored with daily fluoroscopy as a measure of colonic transit. ⋯ Manometric defection patterns were also observed to be similar before SCI and after SCI with electrical stimulation. Based on our scoring criteria, the most frequent response to electrical stimulation was an abdominal contraction. These findings demonstrate that colonic transit is prolonged following SCI and that direct electrical stimulation of the colon following SCI improves colonic transit in an animal model.

Spinal cord stimulation (SCS) has been used for more than 30 years now, and although it has shown to be effective under certain well-described conditions of chronic pain, conclusive evidence on its effectiveness is still sparse. There is a need for more prospective and methodological good studies, in order to prove SCS efficacy for new or still questionable indications and to reveal prognostic factors for successful application. ⋯ In contrast to the early years when SCS was applied by independent physicians exploring the field of neurostimulation, the importance of information exchange and coordination of studies has now been recognized. Recent technical improvements of SCS devices may positively influence clinical outcome.

Multicenter Study Clinical Trial
Risk of avascular necrosis following short term megadose methylprednisolone treatment.
We conducted a prospective cohort study to determine whether administration of large doses of the corticosteroid methylprednisolone following spinal cord injury as recommended in the National Acute Spinal Cord Injury Study-2 (NASCIS-2) protocol results in an increased incidence of avascular necrosis (AVN) of the femoral or humeral head. All subjects were patients treated by a spinal cord injury physician in an Acute Spinal Cord Injury Unit between 1989 and 1996 where some received the megadose steroids while others did not. Patients younger than 15 years and older than 75 years were excluded, as were those with any hip or shoulder disease, with pelvic fracture, or with a history of predisposition to AVN by hip dislocation, excessive alcohol consumption, previous high dose steroid use, or systemic lupus erythematosus. ⋯ Among the 32 spinal cord injured subjects who did not receive steroids (age 16 to 65 years (mean 34 years)), seven were female. There was no case of AVN found in either group. Using binomial distribution, we conclude that the true incidence of AVN among the methylprednisolone treated group is less than 5% (alpha < 0.05) and therefore continue to recommend short term (24 h) methylprednisolone therapy.

This study was designed to test the 1992 International Standards for Neurological and Functional Classification of Spinal Cord Injury. One hundred and six professionals in the field of spinal cord injury attending an instructional course at the 1994 ASIA Meeting participated in the test. Participants completed a pretest and posttest in which they classified two patients who had a spinal cord injury (one with complete tetraplegia and one with incomplete paraplegia) by sensory and motor levels, zone of partial preservation (ZPP), ASIA Impairment Scale and completeness of injury. ⋯ For the patient with incomplete paraplegia (Case 2), scores were considerably lower. Pretest scores ranged from 16% (right motor level) to 95% correct (incomplete injury); posttest scores from 21% (right motor level) to 97% correct (incomplete injury). The results showed that further revisions of the 1992 Standards and more training is needed to ensure accurate classification of spinal cord injury.
