Randomized Controlled Trial Clinical TrialLymphocyte profiles in patients with chronic low back pain enrolled in a clinical trial.
Our earlier findings suggest that patients with musculoskeletal complaints have lower numbers and percentages of natural killer (NK) cells than asymptomatic subjects. This study examines patient lymphocyte profiles, as a secondary outcome measure, in a trial of manipulative therapies to treat chronic low back pain (LBP) of mechanical origin. ⋯ This is the first report of lymphocyte profiles in patients with diagnosed chronic LBP. Our finding of a lower percentage of NK cells in these patients confirms our earlier finding that patients with musculoskeletal problems have a lower percentage of NK cells than do asymptomatic subjects. However, manipulative therapy was not shown to have a clinically significant effect on either the absolute n

The authors hypothesized that the source of coccygodynia was a lesion of the coccygeal disc. ⋯ Common coccygeal pain could come from the coccygeal disc in approximately 70% of cases.

[Treatment of chronic lumbago and radicular pain by spinal cord stimulation. Long-term results].
Seventy-seven patients with chronic, refractory, low back and radicular pain underwent implantation of a spinal cord stimulator between 1984 and 1992. Most patients had failed back surgery syndrome. In every case, an epidural quadripolar "Resume" electrode was implanted surgically. ⋯ Adverse events included one case of meningitis, two cases of local infection, and one case each of cerebrospinal fluid fistula and necrosis of the skin overlying the stimulator. The main causes of treatment failure were complications, inappropriate patient selection, and the escape phenomenon. The results of this study demonstrate that spinal cord stimulation is effective for the treatment of chronic low back and radicular pain in carefully selected patients; scrupulous application of restrictive selection criteria is essential to the success of the method.

A prospective cross-sectional analytic approach was taken. ⋯ In patients with chronic low back pain, the combination of discogenic pain and zygapophyseal joint pain is uncommon.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialParenteral dipyrone versus diclofenac and placebo in patients with acute lumbago or sciatic pain: randomized observer-blind multicenter study.
Two hundred and sixty patients with lumbago or sciatic pain participated in a multicenter observer-blind randomized trial to compare the efficacy and tolerability of dipyrone 2.5 g, diclofenac 75 mg, and placebo administered as an intramuscular injection once daily for the duration of one to two days. The effectiveness of the test treatments in relieving sciatic pain was measured by a visual analog scale (VAS) before and 30 minutes, 1, 2, 3, 6 and 24 hours after each injection. In addition, the patient's general well-being was measured on a 5-point rating scale on day 0, 1 and 2. ⋯ Pain intensity on VAS (primary endpoint) showed a significantly greater reduction with dipyrone than with diclofenac or placebo between 1 and 6 hours after application (p < 0.01) and at the end of the trial (after 48 hours). Improvement in general well-being and minimal finger-toe distance was greatest in the dipyrone group. 59% of the patients with dipyrone assessed the overall efficacy as "excellent" or "very good", compared with 30% with diclofenac, and 18% with placebo. Adverse reactions were reported in only 7 patients (3%), 4 (5%) in the dipyrone, 1 (1%) in the diclofenac, and 2 (2%) in the placebo group.
