A comparison of osteopathic spinal manipulation with standard care for patients with low back pain.

BACKGROUND: The effect of osteopathic manual therapy (i.e., spinal manipulation) in patients with chronic and subchronic back pain is largely unknown, and its use in such patients is controversial. Nevertheless, manual therapy is a frequently used method of treatment in this group of patients. METHODS: We performed a randomized, controlled trial that involved patients who had had back pain for at least three weeks but less than six months. We screened 1193 patients; 178 were found to be eligible and were randomly assigned to treatment groups; 23 of these patients subsequently dropped out of the study. The patients were treated either with one or more standard medical therapies (72 patients) or with osteopathic manual therapy (83 patients). We used a variety of outcome measures, including scores on the Roland-Morris and Oswestry questionnaires, a visual-analogue pain scale, and measurements of range of motion and straight-leg raising, to assess the results of treatment over a 12-week period. RESULTS: Patients in both groups improved during the 12 weeks. There was no statistically significant difference between the two groups in any of the primary outcome measures. The osteopathic-treatment group required significantly less medication (analgesics, antiinflammatory agents, and muscle relaxants) (P< 0.001) and used less physical therapy (0.2 percent vs. 2.6 percent, P<0.05). More than 90 percent of the patients in both groups were satisfied with their care. CONCLUSIONS: Osteopathic manual care and standard medical care had similar clinical results in patients with subacute low back pain. However, the use of medication was greater with standard care.

Renal effects of oral prostaglandin supplementation after ibuprofen in diabetic subjects: a double-blind, placebo-controlled, multicenter trial.

Prostaglandins of the E series (PGE) are known to contribute to the maintenance of renal hemodynamics in subjects with chronic renal insufficiency. Agents that block PGE synthesis, nonsteroidal anti-inflammatory agents (NSAID), are widely used by people with renal insufficiency. This study was undertaken in subjects with renal insufficiency secondary to diabetes to evaluate the acute effects of a PGE1 analog, misoprostol, on NSAID-induced changes in RBF, as calculated by para-aminohippurate clearance, and GFR, as calculated by inulin clearance. Sodium excretion was also assessed. Twenty-five fasting subjects with a mean age of 56 +/- 4 yr received 800 mg of ibuprofen orally. A concomitant dose of either a placebo (PL) or 200 micrograms of misoprostol was also given. This was followed in 1 h by either a placebo or an additional 200-micrograms dose of misoprostol. Measurements for the determination of RBF, GFR, blood pressure, and fractional excretion of sodium were performed every 30 min for the next 5 h. The greatest reduction in both GFR (-25 +/- 7 mL/min per 1.73 m2 PL versus -10 +/- 4 mL/min per 1.73 m2, misoprostol delta GFR; P < 0.05) and RBF (-48 +/- 21 mL/min per 1.73 m2 PL versus -15 +/- 8 mL/min per 1.73 m2, M delta RBF; P < 0.05) occurred approximately 2 h after the NSAID dose. No significant differences were noted in blood pressure, fractional excretion of sodium, or other measured parameters between groups during the entire study. Gastrointestinal upset was the most common side effect observed in both groups.(ABSTRACT TRUNCATED AT 250 WORDS)
