Spontaneous intracranial hypotension (SIH) is a postural headache syndrome unrelated to dural puncture. Because of the increasing failure of epidural blood patch (EBP) to relieve headache in SIH, we retrospectively investigated the epidemiological features and treatment outcomes in 55 cases of SIH. The study population was stratified by age and sex; continuous variables were compared for differences by t-tests; categorical variables were compared by Chi-squared analysis or Fisher exact tests. ⋯ EBP failures were more common in patients aged 40 and younger than in older patients (P = 0.003). Postural headache from SIH was not uniformly responsive to EBP, and had significant comorbidities, especially in men. The management of postural headache in SIH by other techniques to restore brain position and cerebrospinal fluid dynamics should be investigated.

Intradiscal electrothermal annuloplasty (IDET) is an effective treatment for chronic discogenic low back pain (LBP). However, efficacy of IDET for the treatment of referred leg pain has not been examined. This study was performed to assess the long-term efficacy of IDET for the treatment of referred leg pain in chronic discogenic LBP patients. ⋯ A relatively large number of LBP patients who underwent IDET (84%) presented with referred leg pain without sciatica. The IDET procedure afforded improvements in leg pain that correlated well with improvements in back pain (0.75/4 and 0.88/4, respectively). These data suggest that IDET may relieve associated limb pain in chronic discogenic LBP patients.

It is known that, in spite of meeting appropriate clinical criteria for spinal cord stimulation (SCS) and having undergone flawless procedures, a significant number of patients who fail the therapy continues to exist. It is the purpose of this article to focus on the development of psychosocial indicators of success for SCS, if any. Referring to specialist literature authors present a review of what is known, what is not known, and what remains controversial on this topic. ⋯ To improve treatment outcomes of SCS, seems to be essential to perform psychosocial evaluations on all persons clinically indicated for SCS to exclude those patients, who most probably, on a psychosocial level, will fail the procedure. To maximize treatment efficacy, authors believe spinal cord stimulation for chronic pain control must be part of a comprehensive program. An accurate preoperative psychosocial assessment and a course of psychological assistance both before and after therapy seems to be crucial for improving outcomes.

There are numerous treatments for complex regional pain syndrome (CRPS). These treatments are varied in scope and include pain management therapies, psychological therapies, and physiotherapy. Treatment guidelines have been published in the past, but little information exists as to how clinicians utilize these guidelines. Moreover, there has been a paradigm shift from the older "reflex sympathetic dystrophy" (RSD) nomenclature, with largely sympathetic block driven diagnosis and therapy to more recent trends towards more inclusive "CRPS" diagnostic criteria and multidisciplinary treatment. There remains controversy regarding the selection of various techniques, and the timing of advancement through the treatment algorithm to the more aggressive, interventional techniques. We set out to determine current CRPS treatment practices of interventional pain specialists. ⋯ Our survey results revealed the use of a treatment algorithm for CRPS that consists of treatment using medical therapies (pharmacologic, blocks, catheters, and implantable devices), psychological therapies, and physiotherapy in a coordinated fashion. The trend among our survey respondents is to utilize increasingly interventional techniques after a failed 2- to 4-week trial of any one particular therapy.

Published studies of intradiscal thermal annuloplasty (IDTA) have shown at most 50% pain relief as an improved outcome with little focus on functional improvement in the treatment of discogenic pain. Previous studies have used a number of criteria for patient selection including low back pain unresponsive to conservative care, no compressive radiculopathy, positive provocative discography and absence of previous surgery at the same symptomatic level. The purpose of present study is to examine the hypothesis that additional inclusion criteria for patient selection such as disc height, absence of degenerative disc disease (DDD) in untreated discs, absence of herniated nucleus pulposus or lumbar canal stenosis may improve the outcome of treatment. ⋯ We found dramatic improvement of pain scores and ADLs following IDTA when strict patient selection was applied. We believe that IDTA is an effective, minimally invasive treatment for discogenic pain in properly selected patients.
