A new collection technique allows cytologic examination up to 2 weeks after lumbar puncture without loss of cells or morphologic detail. Cerebrospinal fluid (CSF) was allowed to flow directly from a lumbar puncture needle into a solution of Carbowax in ethanol and was then processed with a cytocentrifuge. Two groups of patients were studied -- those undergoing spinal anesthesia and those having myelography for low back pain. Lymphocytes, polymorphonuclear neutrophils, and ependymal cells were regularly found in the CSF; a definite difference was found in the quantity and cell types in the two patient populations. The proposed method may be sensitive enough to aid in the identification of other neurologic diseases with low cell counts.

Low back pain may arise from degenerative changes in the posterior joints of the lumbar spine. These joints are innervated by a branch of the posterior primary ramus, which follows an anatomically constant course. Pain impulses from these joints can be interrupted by coagulating this nerve with a radiofrequency wave, the probe having been placed in the area of the nerve percutaneously. Percutaneous lumbar rhizolysis was carried out under local anesthesia on an outpatient basis in 82 patients, most of whom had multiple level rhizolysis. Rhizolysis was successful in 67% of patients with mechanical low back pain without evidence of disc herniation and nerve-root compression or psychogenic pain, who had not previously undergone an operation for relief of the pain.

In 387 pat., we observed the interdependence of abnormal vertebral column and failures in epidural anaesthesia by medial tap with the "los of resistance" method. We could show that in contradistinction to other opinions scoliosis induces no higher rate of failure of epidural anaesthesia than the normal vertebral column. In patients with kyphoscoliosis and ossified ligaments the epidural space was identified less frequently than in the normal group, perforations of the dura were encountered more frequently. These results are statistically significant. In patients who had or have pain in the back (p.e. lumbago) and those with ossified ligaments we found significantly more pain during operation although analgesia was tested before. In these three abnormalities of the vertebral column we recommend to judicously balance advantages against disadvantages of epidural anaesthesia and alternative anaesthetic procedures.

The effects of spinal anaesthesia were investigated in 67 sportspersons and in 128 sedentary patients (average age 31.8 +/- 6.2 yrs). The most frequent complaint in both groups was mild low back pain (27 cases vs. 58). Postspinal headache was severe and disabling, with an incidence of 13.4% in the sportspersons and 21.1% in the sedentary group. The sedentary group also showed a higher incidence of other postanaesthetic problems. Given the high rate of side effects, the young age of the subjects, and their desire to resume work as soon as possible after the operation, spinal anaesthesia is not the best anaesthetic procedure for this age group.

In an effort to define the origin of low back pain and sciatica, 193 patients were carefully studied using progressive local anesthesia. These patients had surgery for herniated discs, spinal stenoses, or both. Various tissues were stimulated during the performance of these lumbar spinal operations. This article discusses our observations and the results of that study.

In 52 patients 0.5-3.0 ml of iohexol, 180 mg/ml, was injected using lateral injection technique and fluoroscopy control. A total of 146 lumbar discs using local anaesthesia was injected. Two types of premedication were used; either diazepam alone or diazepam in combination with pethidine and glycopyrronium bromide. There was no difference in the discography injection pain between the groups (X2 = 0.774, P greater than 0.05]. During discography, some patients had nausea (2%), convulsions (4%), back pain (6%) and hypotension (10%), but no allergic reactions were seen. This suggests that these immediate reactions are more related to the procedure itself than to the non-ionic ratio 3.0 iohexol contrast medium. More troublesome iatrogenic complications were seen the day after the discography in the form of severe headache (10%) probably related to liquor leakage, and increasing low back pain (81%). The latter may be caused by local haematoma or chemical irritation from iohexol. Patients with no pain during injection had a relatively slight need for analgesics (Somer's D = -0.196, P less than 0.05).

A 75-year-old woman with chronic low back pain was given bupivacaine and methylprednisolone epidurally through a catheter in the L1-L2 interspace. An unusual spread of bupivacaine resulted in a block from the C4 to the L1 dermatome with no relief of back pain. Injection of a radiopaque dye and subsequent X rays showed a similar spread. The possible causes are discussed.

A 43-year-old woman was given an epidural injection of steroid mixed with local anaesthetic, under general anaesthesia, for treatment of low back pain. In the recovery room she complained of blindness in one eye. Fundoscopy revealed retinal and vitreous haemorrhages in both eyes. Retinal haemorrhages can be caused by an increase in intracranial pressure and are therefore a possible complication of epidural anaesthesia.

Percutaneous diskectomy is a new treatment used in surgery of the spine for the treatment of herniated lumbar disks. The idea is to carry out an exeresis with a posterolateral percutaneous approach on a part of the herniated intervertebral disk; while always remaining outside the spinal canal. This technique eliminates the risks of fibrosis or arachnoiditis. It is carried out under local anesthesia, reduces the surgical insult and requires only a short stay in hospital. Between 1984 and 1988, 188 operations using this technique were carried out on L3-L4, L4-L5 and L5-S1. Of the first 100 cases studied, we note: 71% good and very good results for radiculalgia after a time lapse of more than a year, 51% good and very good results for low back pain; 16% of the patients required a surgical approach after percutaneous diskectomy. The authors specify the advantages and the indications of this surgical technique, which complements the traditional lumbar intervertebral disk surgery.

Acupuncture has been used in the treatment of a variety of illnesses for more than 2000 years. The practice of acupuncture is based on a theoretical system different from our understanding of human anatomy and physiology, and has developed through experience and observation. Stimulation of selective acupoints (situated along 'meridians' in the body) by inserting needles is believed to restore bodily functions by promoting the flow of 'vital energy', throughout the system. Other forms of stimulation which have been developed are heat, electrical stimulation, magnetism and, recently, laser. Laser acupuncture offers distinct advantages over the traditional method because the procedure is pain-free and non-traumatic. Clinical applications include the control of pain in osteoarthritis, lumbago and migraine, and anaesthesia for certain surgical procedures, as well as other ailments of the cardiovascular, respiratory and nervous systems. The technique is easy to learn and there is no need for sophisticated instruments. Thus it is especially useful in developing countries where health resources are limited.
