Raynaud’s Syndrome

Raynaud's Syndrome Disease ChiropractorImproper functioning of the nervous system can affect blood vessels, most frequently those of the fingers and toes, causing the blood vessels to constrict when a person is cold or experiencing stress. This results in less blood flowing to the extremities, which then turn white or blue. It can often be painful when blood flow returns to the affected digits.

Raynaud’s Syndrome is a condition of recurring episodes of angiospasm of peripheral arteries, predominantly the arterioles. This angiospastic disorder presents clinically in a symmetrical pattern affecting the upper extremities and is commonly seen in females ■

Filed under: Research, Spinewave Bulletin 

Objective: To investigate the efficacy and tolerability of analgesic and adjuvant pain drugs typically administered in primary care for the management of patients with sciatica.

Design: Systematic review.

Data source: International Pharmaceutical Abstracts, PsycINFO, Medline, Embase, Cochrane Central Register of Clinical Trials (CENTRAL), CINAHL, and LILACS.

Study selection: Randomised controlled trials assessing the efficacy and tolerability of drugs versus placebo or other treatment for sciatica.

Data extraction: Two independent reviewers extracted data and assessed methodological quality using the PEDro scale. Pain and disability outcomes were converted to a common 0 to 100 scale. Data was pooled with a random effects model, and the GRADE approach was used in summary conclusions.

Results: Twenty three published reports met the inclusion criteria. The evidence to judge the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids, antidepressants, anticonvulsants, muscle relaxants, and opioid analgesics ranged from moderate to low quality. Most of the pooled estimates did not favour the active treatment over placebo. The pooled results of two trials of corticosteroids and a single trial of the anticonvulsant gabapentin for chronic sciatica showed some benefits but only in the short term. The median rate of adverse events was 17% for the active drugs and 11% for placebo. Trial limitations included failure to use validated outcome measures, lack of long term follow-up, and small sample size.

Conclusions: As the existing evidence from clinical trials is of low quality, the efficacy and tolerability of drugs commonly prescribed for the management of sciatica in primary care is unclear.
