Review Meta Analysis
A systematic review of paracetamol for non-specific low back pain.
The objective of this study was to assess the efficacy of paracetamol (acetaminophen) in the treatment of pain and disability in patients with non-specific low back pain. We conducted a systematic review of randomized controlled trials to assess the efficacy of paracetamol in the treatment of pain and disability in patients with non-specific low back pain. A search for randomized controlled trials was conducted using the Medline, Embase and CINAHL databases. ⋯ No trial reported a statistically significant difference in favor of paracetamol. There is insufficient evidence to assess the efficacy of paracetamol in patients with low back pain. There is a clear need for large, high quality randomized controlled trials evaluating paracetamol, to provide reliable evidence of paracetamol's effectiveness in patients with low back pain and to establish the validity of the recommendations in clinical guidelines.

Randomized Controlled Trial
Preliminary results of a randomized, equivalence trial of fluoroscopic caudal epidural injections in managing chronic low back pain: Part 3--Post surgery syndrome.
Post surgery syndrome resulting in persistent pain following lumbar spine surgery is common. Speculated causes of post lumbar surgery syndrome include stenosis, degeneration of adjacent segments, internal disc disruption, recurrent disc herniation, retained disc fragment, epidural or intraneural fibrosis, radiculopathy, and various other causes. Epidural injections are most commonly used in post surgery syndrome. There is lack of evidence for the effectiveness of epidural injections in managing chronic low back pain with or without lower extremity pain secondary to post surgery syndrome. ⋯ Caudal epidural injections in chronic function-limiting low back pain in post surgery syndrome without facet joint pain demonstrated effectiveness with over 55% of the patients showing improvement in functional status with significant pain relief in 60% to 70%.

Most patients seeking help for back pain are managed in primary care. ⋯ Treatment received by patients with back pain was varied and often not in line with back-pain guidelines, particularly with respect to opioid prescription and X-ray investigation. The content of the 'usual care' arm in trials is crucial to interpreting the outcome of studies, but was poorly described in the papers reviewed. Future trials should more fully describe the 'usual care' arm.

Case Reports
Intravascular injection of contrast during lumbar discography: a previously unreported complication.
Report a case of intravascular contrast injection during lumbar discography. ⋯ Vascular uptake of contrast can occur during lumbar discography, even when the needle tip is ideally located.

Randomized Controlled Trial
Preliminary results of a randomized, equivalence trial of fluoroscopic caudal epidural injections in managing chronic low back pain: Part 4--Spinal stenosis.
Spinal stenosis is one of the 3 most common diagnoses of low back and leg symptoms which also include disc herniation and degenerative spondylolisthesis. Spinal stenosis is a narrowing of the spinal canal with encroachment on the neural structures by surrounding the bone and soft tissue. In the United States, one of the most commonly performed interventions for managing chronic low back pain are epidural injections, including their use for spinal stenosis. However, there have not been any randomized trials and evidence is limited with regards to the effectiveness of epidural injections in managing chronic function-limiting low back and lower extremity pain secondary to lumbar spinal stenosis. ⋯ Caudal epidural injections with or without steroids may be effective in patients with chronic function-limiting low back and lower extremity pain with spinal stenosis in approximately 60% of the patients.
