Acupuncture for neck disorders.

STUDY DESIGN: Systematic review. OBJECTIVE: To determine the effects of acupuncture for individuals with neck pain. SUMMARY OF BACKGROUND DATA: Neck pain is one of the 3 most frequently reported complaints of the musculoskeletal system. Treatments for neck pain are varied, as are the perceptions of benefits. METHODS.: We searched CENTRAL (2006, issue 1) and MEDLINE, EMBASE, MANTIS, Cumulative Index to Nursing and Allied Health Literature from their beginning to February 2006. We searched reference lists and the acupuncture database TCMLARS in China. Any published trials using randomized (RCT) or quasi-randomized (quasi-RCT) assignment to the intervention groups, either in full text or abstract form, were included. RESULTS: We found 10 trials that examined acupuncture treatments for chronic neck pain. Overall, methodologic quality had a mean of 2.3 of 5 on the Jadad scale. For chronic mechanical neck disorders, there was moderate evidence that acupuncture was more effective for pain relief than some types of sham controls, measured immediately posttreatment. There was moderate evidence that acupuncture was more effective than inactive, sham treatments measured immediately posttreatment, and at short-term follow-up (pooled standardized mean difference, -0.37; 95% confidence interval, -0.61 to -0.12). There was limited evidence that acupuncture was more effective than massage at short-term follow-up. For chronic neck disorders with radicular symptoms, there was moderate evidence that acupuncture was more effective than a wait-list control at short-term follow-up. CONCLUSIONS: There is moderate evidence that acupuncture relieves pain better than some sham treatments, measured at the end of the treatment. There is moderate evidence that those who received acupuncture reported less pain at short-term follow-up than those on a waiting list. There is also moderate evidence that acupuncture is more effective than inactive treatments for relieving pain posttreatment, and this is maintained at short-term follow-up.

Mechanical traction for mechanical neck disorders: a systematic review.

OBJECTIVE: To assess whether mechanical traction, either alone or in combination with other treatments, improves pain, function/disability, patient satisfaction and global perceived effect in adults with mechanical neck disorders. METHODS: We conducted a systematic review up to September 2004 of randomized controlled trials and used pre-defined levels of evidence for qualitative analysis. Two independent reviewers conducted study selection, data abstraction and methodological quality assessment. Using a random effects model, relative risk and standardized mean differences were calculated. The reasonableness of combining studies was assessed on clinical and statistical grounds. In the absence of heterogeneity, pooled effect measures were calculated. RESULTS: Of the 10 selected trials, one study was of high quality. Our review revealed low-quality trials for mechanical neck disorders, showing evidence of benefit favouring intermittent traction for pain reduction. Continuous traction showed no significant difference for defined outcomes. CONCLUSION: Inconclusive evidence for continuous and intermittent traction exists due to trial methodological quality. Two clinical conclusions may be drawn, one favouring the use of intermittent traction and the other not supporting the use of continuous traction. Attention to research design flaws and description of traction characteristics is needed.

International Clinical Epidemiology Network: an opportunity for SGIM international cooperation.

The Canadian/American regional group of the International Clinical Epidemiology Network (INCLEN) invites SGIM members to join in an international network dedicated to improving health in low and middle-income countries and reducing health disparities in North America-not only because many goals and activities of the 2 organizations are compatible such as evidence-based medicine, mentoring, and training; but because collaboration between SGIM and INCLEN could strengthen both groups. With increasing brain drain from the developing world to the North, there is an ever-increasing need for academic contributions from the North to swing the balance toward brain gain for the South. SGIM members have the academic expertise to make an important contribution to global health. Participation and contribution from SGIM members is welcomed at the individual or organizational level. We invite you to explore possible partnership and collaboration.

Placebos: our most effective therapy?

Placebos remain highly controversial therapies largely because of their widespread use in research as a comparator rather than a focus of analysis. While a recent systematic review of placebo versus no therapy arms in trials found no difference, the placebo effect in some areas of drug trial research is large and increasing. We attempt to explain this paradox and suggest how clinicians may use the placebo effect to advantage.

Patients' consent preferences for research uses of information in electronic medical records: interview and survey data.

OBJECTIVES: To assess patients' preferred method of consent for the use of information from electronic medical records for research. DESIGN: Interviews and a structured survey of patients in practices with electronic medical records. SETTING: Family practices in southern Ontario, Canada. PARTICIPANTS: 123 patients: 17 were interviewed and 106 completed a survey. MAIN OUTCOME MEASURES: Patients' opinions and concerns on use of information from their medical records for research and their preferences for method of consent. RESULTS: Most interviewees were willing to allow the use of their information for research purposes, although the majority preferred that consent was sought first. The seeking of consent was considered an important element of respect for the individual. Most interviewees made little distinction between identifiable and anonymised data. Research sponsored by private insurance firms generated the greatest concern, and research sponsored by foundation the least. Sponsorship by drug companies evoked negative responses during interview and positive responses in the survey. CONCLUSIONS: Patients are willing to allow information from their medical records to be used for research, but most prefer to be asked for consent either verbally or in writing.

Effect of vitamin D on bone mineral density of elderly patients with osteoporosis responding poorly to bisphosphonates.

BACKGROUND: Bisphosphonates are indicated in the prevention and treatment of osteoporosis. However, bone mineral density (BMD) continues to decline in up to 15% of bisphosphonate users. While randomized trials have evaluated the efficacy of concurrent bisphosphonates and vitamin D, the incremental benefit of vitamin D remains uncertain. METHODS: Using data from the Canadian Database of Osteoporosis and Osteopenia (CANDOO), we performed a 2-year observational cohort study. At baseline, all patients were prescribed a bisphosphonate and counseled on vitamin D supplementation. After one year, patients were divided into two groups based on their response to bisphosphonate treatment. Non-responders were prescribed vitamin D 1000 IU daily. Responders continued to receive counseling on vitamin D. RESULTS: Of 449 patients identified, 159 were non-responders to bisphosphonates. 94% of patients were women. The mean age of the entire cohort was 74.6 years (standard deviation = 5.6 years). In the cohort of non-responders, BMD at the lumbar spine increased 2.19% (p < 0.001) the year after vitamin D was prescribed compared to a decrease of 0.55% (p = 0.36) the year before. In the cohort of responders, lumbar spine BMD improved 1.45% (p = 0.014) the first year and 1.11% (p = 0.60) the second year. The difference between the two groups was statistically significant the first year (p < 0.001) but not the second (p = 0.60). Similar results were observed at the femoral neck but were not statistically significant. CONCLUSION: In elderly patients with osteoporosis not responding to bisphosphonates, vitamin D 1000 IU daily may improve BMD at the lumbar spine.
