BACKGROUNDVisceral pain is a common cause for seeking medical attention. Afferent fibers innervating viscera project to the central nervous system via sympathetic nerves. The lumbar sympathetic nerve trunk lies in front of the lumbar spine. Thus, it is possible for patients to suffer visceral pain originating from sympathetic nerve irritation induced by anterior herniation of the lumbar disc. This study aimed to evaluate lumbar discogenic visceral pain and its treatment.

METHODSTwelve consecutive patients with a median age of 56.4 years were enrolled for investigation between June 2012 and December 2012. These patients suffered from long-term abdominal pain unresponsive to current treatment options. Apart from obvious anterior herniation of the lumbar discs and high signal intensity anterior to the herniated disc on magnetic resonance imaging, no significant pathology was noted on gastroscopy, vascular ultrasound, or abdominal computed tomography (CT). To prove that their visceral pain originated from the anteriorly protruding disc, we evaluated whether pain was relieved by sympathetic block at the level of the anteriorly protruding disc. If the block was effective, CT-guided continuous lumbar sympathetic nerve block was finally performed.

RESULTSAll patients were positive for pain relief by sympathetic block. Furthermore, the average Visual Analog Scale of visceral pain significantly improved after treatment in all patients (P < 0.05). Up to 11/12 patients had satisfactory pain relief at 1 week after discharge, 8/12 at 4 weeks, 7/12 at 8 weeks, 6/12 at 12 weeks, and 5/12 at 24 weeks.

CONCLUSIONSIt is important to consider the possibility of discogenic visceral pain secondary to anterior herniation of the lumbar disc when forming a differential diagnosis for seemingly idiopathic abdominal pain. Continuous lumbar sympathetic nerve block is an effective and safe therapy for patients with discogenic visceral pain.

OBJECTIVETo evaluate clinical significance of waist soft tissue tension detection in treating chronic nonspecific low back pain.

METHODSFrom August 2011 to March 2012,60 patients with chronic nonspecific low back pain were divided into two groups (sliver needle group and TCM fumigation group) according to propotion of 1:1. In sliver needle group, there were 17 males and 13 females aged from 28 to 55 years old with an average age of (45.70 +/- 4.15), treated with sliver needle; In TCM fumigation group,there were 19 males and 11 females aged from 27 to 55 years old with an average age of (43.03 +/- 5.86), treated with TCM fumigation. Changes of force-displacement distance (FDD), specific absorption rate (S) of two groups were observed before treatment, 1 week and 3 months after treatment respectively, VAS scoring and Roland-Morris disability questionnaire (RMDQ) were used to access clinical effects.

RESULTS(1) VAS score of silver needle group was 4.77 +/- 0.78, 1.99 +/- 1.08 and 2.55 +/- 0.94, respectively before treatment, at 1 week and 3 months after treatment,while VAS score in TCM fumigation group were 4.43 +/- 0.61, 2.48 +/- 0.71 and 3.05 +/- 0.86, respectively. VAS score of two groups after treatment were sigificant decrease than that of before treatment (P < 0.05). There was no sigificant differences between two groups before treatment, but sliver needle group performed well in analgesia than TCM fumigation group, and had obvious differences (P < 0.05). RMDQ score of silver needle group was 13.63 +/- 1.96, 5.87 +/- 2.33 and 6.53 +/- 2.89, respectively before treatment, at 1 week and 3 months after treatment, while RMDQ score in TCM fumigation group were 13.40 +/- 2.01, 6.90 +/- 2.31, 9.23 +/- 2.87, respectively. There was no significant differences between two groups before treatment and 1 week after treatment (P > 0.05), and had obvious differences between two groups at 3 months after treatment (P < 0.01). Both groups could obvious improve dysfunction caused by chronic low back pain, and curative effect of sliver needle groups was more endurable. (2) Following-up at 3 months after treatment, FDD of multifidus, erector spinae of effected side and multifidus of healthy in sliver needle group were obvious increased (P < 0.05); In TCM fumigation group, FDD of multifidus and erector spinae on both side were increased at 1 week after treatment (P < 0.05), but had no significant meaning at 3 months after treatment on health side (P>0.05). There was no significant meaning before treatment (P > 0.05), FDD of multifidus, erector spinae of effected side in sliver needle group were obvious increased at 1 week after treatment (P < 0.05); but no obvious meaning on health side. FDD of both side in sliver needle group were obvious increased at 3 months after treatment. (3) There was correlation among differences of FDD in multifidus and erector spinae, VAS score and differences of RMDQ, and Spearman correlation coefficient R was 0.517, 0.811, 0.746 and 0.625; There was correlation between items of soft tissue tension and sympotoms, function and life quality. Conclusion:Soft tissue tension detection can effectively manifest degree of pain and dysfunction of low back, and improve objectivity of therapeutic evaluation for chronic low back pain.

PURPOSE: The pathological mechanism of lumbar spinal stenosis is reduced blood flow in nerve roots and degeneration of nerve roots. Exercise and prostaglandin E1 is used for patients with peripheral arterial disease to increase capillary flow around the main artery and improve symptoms; however, the ankle-brachial index (ABI), an estimation of blood flow in the main artery in the leg, does not change after treatment. Lumbar spinal nerve roots contain somatosensory, somatomotor, and unmyelinated autonomic nerves. Improved blood flow by medication with prostaglandin E1 and decompression surgery in these spinal nerve roots may improve the function of nerve fibers innervating muscle, capillary, and main vessels in the lower leg, resulting in an increased ABI. The purpose of the study was to examine whether these treatments can improve ABI. MATERIALS AND METHODS: One hundred and seven patients who received conservative treatment such as exercise and medication (n=56) or surgical treatment (n=51) were included. Low back pain and leg pain scores, walking distance, and ABI were measured before treatment and after 3 months of conservative treatment alone or surgical treatment followed by conservative treatment. RESULTS: Low back pain, leg pain, and walking distance significantly improved after both treatments (p<0.05). ABI significantly increased in each group (p<0.05). CONCLUSION: This is the first investigation of changes in ABI after treatment in patients with lumbar spinal stenosis. Improvement of the spinal nerve roots by medication and decompression surgery may improve the supply of blood flow to the lower leg in patients with lumbar spinal stenosis.

BACKGROUND: Although both pregabalin and gabapentin are known to be useful for treating lumbar radiating pain and reducing the incidence of surgery, the oral corticosteroids sometimes offer a dramatic effect on severe radiating pain despite the lack of scientific evidence. METHODS: A total of 54 patients were enrolled among 703 patients who complained of lumbar radiating pain. Twenty patients who received an oral corticosteroid was classified as group A and 20 patients who received the control drugs (pregabalin or gabapentin) as group B. Oswestry Disability Index (ODI), Revised Roland Morris disability questionnaire (RMDQ), Short Form 36 (SF-36) questionnaire, lumbar radiating pain, objective patient satisfaction, and objective improvement of patients or physicians were assessed at 2, 6, and 12 weeks after medication. RESULTS: No difference in the sex ratio and age was observed between the groups (p = 0.70 and p = 0.13, respectively). Group A showed greater improvement in radiating pain after 2, 6, and 12 weeks than group B (p < 0.001, p = 0.001, and p < 0.001, respectively). No differences were observed between the groups in satisfaction at the beginning and 12 weeks after taking the medication (p = 0.062 and p = 0.061, respectively) and in objective improvement of patients and physicians (p = 0.657 and p = 0.748, respectively). Group A was less disabled and had greater physical health scores than group B (p = 0.014 and p = 0.017, respectively). CONCLUSIONS: Oral corticosteroids for the treatment of lumbar radiating pain can be more effective in pain relief than gabapentin or pregabalin. The satisfaction of patients and physicians with the drug and objective improvement status were not inferior to that with gabapentin or pregabalin.
