A randomized double-blind dose-titration crossover trial of the safety and efficacy of oral fampridine-SR (sustained release 4-aminopyridine) was conducted on spinal cord injured (SCI) patients at two centers. Twenty-six patients (n = 26) with incomplete lesions completed the trial. These patients all had chronic (>2 years) and stable neurological deficits. They received fampridine-SR 12.5 and 17.5 mg b.i.d. over a 2-week treatment period, followed by a 1-week washout and 2 weeks of placebo, or vice versa. Patients reported significant benefit of fampridine-SR over placebo on patient satisfaction (McNemar's test, p2 < 0.05) and quality of life scores (p2 < 0.01). Sensory scores (p1 < 0.01), including both pin prick (p1 = 0.059) and light touch (p1 = 0.058), and motor scores (adjusted to reflect only paretic segments) (p1 < 0.01) all yielded evidence of benefit of fampridine-SR over placebo. The Ashworth scale of spasticity was significantly (p2 < 0.05) reduced when patients received fampridine-SR. There were no statistically significant benefits of the drug on measures of pain or bowel, bladder and sexual function, or functional independence. Side effects of lightheadedness and nausea were transient and trivial relative to efficacy, and approximately 30% of patients reported a wish to continue to use fampridine-SR. The clinical benefits most likely derive from the K+ channel blocking action of the drug. Potassium channel blockade enhances axonal conduction across demyelinated internodes and enhances neuroneuronal and neuromuscular transmission in preserved axons. These results provide the first evidence of therapeutic benefit of fampridine-SR in SCI patients.

The use of standing devices by spinal cord-injured subjects was investigated through a national survey of a sample of individuals who returned their manufacturer's warranty card to two companies. We obtained a 32% response rate (99/310). The majority of respondents were male (87%) with a median age between 41 and 50 years. Seventy-seven percent were paraplegic and 21% were quadriplegic. Forty percent had between 1 and 5 years experience with their device, and 84% of those responding were currently using their standing device. Forty-one percent used their standing device one to six times a week; two-thirds stood between 30 minutes and 1 hour for each use. Less than 10% of subjects experienced any side effects, such as nausea or headaches, from standing. Twenty-one percent of subjects reported being able to empty their bladder more completely. There was also a favorable response by some individuals on the effects of the standing devices on bowel regularity, reduction of urinary tract infections, leg spasticity, and number of bed sores. Finally, 79% of subjects highly recommended use of standing devices to other people with spinal cord injury. The positive responses of individuals using standing devices is a strong recommendation for the assistive technology community to make these devices more available to individuals with spinal cord injury.

The plant Cannabis sativa has a long history of medical use in the treatment of pain and spasms, the promotion of sleep, and the suppression of nausea and vomiting. However, in the early 70s cannabis was classified in the Narcotic Acts in countries all over the world as having no therapeutic benefit; therefore, it cannot be prescribed by physicians or dispensed by pharmacists. In the light of this contradictory situation an increasing number of patients practices a self-prescription with cannabis products for relieving a variety of symptoms. An anonymous standardized survey of the medical use of cannabis and cannabis products of patients in Germany, Austria and Switzerland was conducted by the Association for Cannabis as Medicine (Cologne, Germany). During about one year 170 subjects participated in this survey; questionnaires of 128 patients could be included into the evaluation. 68% of these participants were males, 32% females, with a total mean age of 37.5 (+/- 9.6) years. The most frequently mentioned indications for medicinal cannabis use were depression (12.0%), multiple sclerosis (10.8%), HIV-infection (9.0%), migraine (6.6%), asthma (6.0%), back pain (5.4%), hepatitis C (4. 8%), sleeping disorders (4.8%), epilepsy (3.6%), spasticity (3.6%), headache (3.6%), alcoholism (3.0%), glaucoma (3.0%), nausea (3.0%), disk prolapse (2.4%), and spinal cord injury (2.4%). The majority of patients used natural cannabis products such as marihuana, hashish and an alcoholic tincture; in just 5 cases dronabinol (Marinol) was taken by prescription. About half of the 128 participants of the survey (52.4%) had used cannabis as a recreational drug before the onset of their illness. To date 14.3% took cannabis orally, 49.2% by inhalation and in 36.5% of cases both application modes were used. 72.2% of the patients stated the symptoms of their illness to have 'much improved' after cannabis ingestion, 23.4% stated to have 'slightly improved', 4.8% experienced 'no change' and 1.6% described that their symptoms got 'worse'. Being asked for the satisfaction with their therapeutic use of cannabis 60.8% stated to be 'very satisfied', 24.0% 'satisfied', 11.2% 'partly satisfied' and 4.0% were 'not satisfied'. 70.8% experienced no side effects, 26.4% described 'moderate' and 3.3% 'strong' side effects. 84.1% of patients have not felt any need for dose escalation during the last 3 months, 11.0% had to increase their cannabis dose 'moderately' and 4.8% 'strongly' in order to maintain the therapeutic effects. Thus, this survey demonstrates a successful use of cannabis products for the treatment of a multitude of various illnesses and symptoms. This use was usually accompanied only by slight and in general acceptable side effects. Because the patient group responding to this survey is presumably highly selected, no conclusions can be drawn about the quantity of wanted and unwanted effects of the medicinal use of the hemp plant for particular indications.

Intrathecal baclofen infusion has demonstrated effectiveness in decreasing spasticity of spinal origin. Oral antispasticity medication is minimally effective or not well tolerated in cerebral palsy. This study assessed the effectiveness of intrathecal baclofen in reducing spasticity in cerebral palsy. Candidates were screened by randomized, double-blind, intrathecal injections of baclofen and placebo. Responders were defined as those who experienced an average reduction of 1.0 in the lower extremities on the Ashworth Scale for spasticity. Responders received intrathecal baclofen via the SynchroMed System and were followed for up to 43 months. Fifty-one patients completed screening and 44 entered open-label trials. Lower-extremity spasticity decreased from an average baseline score of 3.64 to 1.90 at 39 months. A decrease in upper extremity spasticity was evidenced over the same study period. Forty-two patients reported adverse events. Most common reports were hypotonia, seizures (no new onset), somnolence, and nausea or vomiting. Fifty-nine percent of the patients experienced procedural or system-related events. Spasticity in patients with cerebral palsy can be treated effectively by continuous intrathecal baclofen. Adverse events, although common, were manageable.

Dr. Leo Hollister's excellent article begins to address the need for better understanding of the effects of cannabis use on health. The last five years in the US have seen an increase in advocacy groups extolling the medicinal utility of cannabis. On 5 November 1996, this culminated in California (proposition 215) joining the list of states permitting the limited use of cannabis for the medicinal treatment of disorders including intractable pain, glaucoma, nausea induced by chemotherapy for cancer or by AZT or Foscavir for the treatment of AIDS, and for spasticity associated with multiple sclerosis (Burstein, 1997; West and Homi, 1996; Grinspoon and Bakalar, 1995; Nahas and Manger, 1995). Of these potential uses for cannabis, the evidence for the treatment of nausea and the stimulation of appetite in cachetic patients appears most promising (for a review see Voth and Schwartz, 1997). Yet not only do doubts remain about the effectiveness of cannabis for the treatment of these conditions, since definitive controlled clinical studies are typically lacking (Voelker, 1997), but there is concern that any therapeutic advantage is more than offset by its harmful effects. Within this context of increased medical sanction for the use of cannabis in specific disease states for which it may have therapeutic potential, evaluating its risks vs. benefits profile is essential to rational prescribing. In addition, evaluating the public health risks associated with reports of increased risks of cannabis use (Robertson et al., Poulton et al., 1997), is of concern to advocates of its widespread legalization, governmental agencies attempting to limit its promulgation, and to planners and providers of health care charged with providing treatment for its consequences.

A case of a 37-year-old man with urinary retention secondary to aseptic meningitis is described. He was admitted to our hospital with complaints of fever, nausea, headache, and gait disturbance. He had begun treatment 1 week previously for high fever, headache and joint pain at an outpatient department. On admission, neurological examination revealed neck stiffness, spasticity and hyperreflexia of the extremities, hypesthesia of the lower extremities, and ataxic gait. A spinal fluid examination revealed aseptic meningitis. Disturbed consciousness, diplopia, aphasia, tetraparesis, and urinary retention appeared after admission. Computed tomography and magnetic resonance imaging (MRI) of the head revealed no abnormal lesions. On the 2nd day of hospitalization, a Foley catheter was inserted for urinary retention. The patient was treated with conservative therapy, and his symptoms gradually resolved. The Foley catheter was removed on hospital day 13, but bladder dysfunction was persisted. MRI of the lumbar spine revealed herniated lumbar discs at level L3-4, L4-5, and L5-S1, but the nerve roots were not compressed. The patient was managed with clean intermittent catheterization for more than two weeks. Cystometry revealed atonic bladder. Nineteen cases of urinary retention secondary to aseptic meningitis have been reported in the previous literature. We reviewed their clinical presentation and treatment.

The evidence for the therapeutic efficacy of cannabinoids in the treatment of multiple sclerosis (MS) is increasing but is not as yet convincing. Although several trials have reported no significant effect, the majority of the evidence which supports a beneficial effect on spasticity and pain is based on subjective measurements in trials where unblinding was likely to be a problem. The available clinical trial data suggest that the adverse side effects associated with using cannabis-based medicinal extracts (CBMEs) are generally mild, such as dry mouth, dizziness, somnolence, nausea and intoxication, and in no case did toxicity develop. However, most of these trials were run over a period of months and it is possible that other adverse side effects, not seen in these short-term studies, could develop with long-term use. Despite the evidence that cannabinoids can disrupt cognitive function and promote depression, on the basis of current data, such adverse effects seem unlikely to be associated with the use of CBMEs. Likewise, there is no evidence to suggest that their effects on balance and motor control, or immune function, may be clinically significant. There is, however, reason to be concerned about the use of therapeutic cannabinoids by people predisposed to psychosis and by pregnant women, given the increasing evidence of their adverse effects on the fetus. In conclusion, given the modest therapeutic effects of cannabinoids demonstrated so far, and the risk of long-term adverse side effects, there is reason to be cautious about their use in the treatment of MS.

Cancer pain treatment should follow the recommendations of the World Health Organisation. Treatment should be with oral application, regular application times and following the analgesic step-ladder. Non-opioids such as dipyrone or non-steroids are used for slight to moderate pain, step-2 opioids such as tramadol or tilidine/naloxone for moderate pain and step-3 opioids such as morphine, oxycodone or hydromorphone for severe pain. Transdermal application of fentanyl or buprenorphine offer a non-invasive parenteral alternative for patients with stable pain syndromes. Cannabinoids such as tetrahydrocannabinol offer a valuable add-on option for cancer patients with refractory pain, spasticity, nausea or appetite loss.

Cannabis sativa L. is possibly one of the oldest plants cultivated by man, but has remained a source of controversy throughout its history. Whether pariah or panacea, this most versatile botanical has provided a mirror to medicine and has pointed the way in the last two decades toward a host of medical challenges from analgesia to weight loss through the discovery of its myriad biochemical attributes and the endocannabinoid system wherein many of its components operate. This study surveys the history of cannabis, its genetics and preparations. A review of cannabis usage in Ancient Egypt will serve as an archetype, while examining first mentions from various Old World cultures and their pertinence for contemporary scientific investigation. Cannabis historians of the past have provided promising clues to potential treatments for a wide array of currently puzzling medical syndromes including chronic pain, spasticity, cancer, seizure disorders, nausea, anorexia, and infectious disease that remain challenges for 21st century medicine. Information gleaned from the history of cannabis administration in its various forms may provide useful points of departure for research into novel delivery techniques and standardization of cannabis-based medicines that will allow their prescription for treatment of these intractable medical conditions.

This paper will review the lumbosacral spine (L1-S5). Procedures performed in the lumbosacral spine include electromyography, spinal stimulator implants, spinal infusion implants for spasticity or pain medications, sacroiliac spine injections, facet blocks, and steroid injections. Complications from these procedures include iatrogenic paraplegia or paraplegia due to transverse myelitis, intravascular penetration, dural puncture, increased pain at the injection site, increased radicular pain, increased spine pain, lightheadedness, nausea, nonspecific headache, and vomiting. Long-term complications include implant infection, implant or catheter dislodgment/kinking, and device failure. This paper provides anatomically accurate schematics of innervations of the lumbosacral spine (L1-S5) that can be used to interpret magnetic resonance images of the muscles and nerves. Cross-sectional schematics of the lumbosacral spine were drawn as they appear on imaging projections. The relevant nerves were color coded. The muscles and skin surfaces were labeled and assigned the color of the appropriate nerves. An organized comprehensive map of the motor innervation of the lumbosacral spine allows the physician to increase the accuracy and efficacy of interventional procedures. This anatomical map could also assist the electromyographer in correlating the clinical and electrophysiological findings on magnetic resonance images.
