Multicenter Study Comparative Study
Linguistic adaptation, validation and comparison of 3 routinely used neuropathic pain questionnaires.
Neuropathic pain questionnaires are efficient diagnostic tools for neuropathic pain and play an important role in neuropathic pain epidemiologic studies in China. No comparison data was available in regards to the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS), the Neuropathic Pain Questionnaire (NPQ) and ID Pain within and among the same population. ⋯ The Chinese versions of LANSS and ID Pain developed and validated by this study can be used as a diagnostic tool in differentiating neuropathic pain in patients whose native language is Chinese (Mandarin).

Discogenic, facet joint, and sacroiliac joint mediated axial low back pain may be associated with overlapping pain referral patterns into the lower limb. Differences between pain referral patterns for these three structures have not been systematically investigated. ⋯ The presence or absence of thigh pain possesses a significant correlation on the source of CLBP for varying ages, whereas the presence of hip/girdle pain or leg pain did not significantly discriminate among IDD, FJP, or SIJP as the etiology of CLBP. Younger age was predictive of IDD regardless of the presence or absence of thigh pain.

Clinical Trial
A prospective evaluation of complications of 10,000 fluoroscopically directed epidural injections.
Among the multiple modalities of treatments available in managing chronic spinal pain, including surgery and multiple interventional techniques, epidural injections by various routes, such as interlaminar epidural injections, caudal epidural injections, transforaminal epidural injections, and percutaneous adhesiolysis are common. Even though the complications of fluoroscopically directed epidural injections are fewer than blind epidural injections, and have better effectiveness, multiple complications have been reported in scattered case reports, with only minor complications in randomized or non-randomized studies and systematic reviews. Thus, prospective studies with large patient series are essential to determine the types and incidences of complications. ⋯ This study illustrates that major complications are rare and minor side effects are common.

Chronic spinal pain is common along with numerous modalities of diagnostic and therapeutic interventions utilized, creating a health care crisis. Facet joint injections and epidural injections are the 2 most commonly utilized interventions in managing chronic spinal pain. While the literature addressing the effectiveness of facet joint nerve blocks is variable and emerging, there is paucity of literature on adverse effects of facet joint nerve blocks. ⋯ This study illustrate that major complications are extremely rare and minor side effects are common.

Case Reports
Minimally invasive interventional therapy for Tarlov cysts causing symptoms of interstitial cystitis.
Tarlov cysts (TC) are present in 4.6% of the population and represent a potential source of chronic pain. When present at lumbosacral levels, symptoms are classically described as perineal pain/pressure, radiculopathy, and headache. Treatment outlined to date primarily includes cyst drainage with fibrin glue sealant and surgical interventions. ⋯ Use of caudal epidural steroid injections proved beneficial in the treatment of pelvic pain symptomatology and so may be considered as an option in patients with identified sacral TC.
