Adenomyosis — an unusual cause of sciatic pain

Summary We report the case of a female patient who presented with a 5-month history of sciatic pain. She was referred to us for investigation and eventual surgical treatment of a suspected herniated lumbar intervertebral disc. Because of an ill-defined clinical picture at admission, she was treated conservatively. After 2 weeks without any improvement, imaging of the spine by MR was performed. No signs of a herniated disc or intraspinal, space-occupying lesion were apparent, but a right paramedian pelvic mass was seen. Ultrasonography confirmed an enlarged, irregular uterus. Hysterectomy abolished the symptoms.     

模特征对伴单侧坐骨神经痛的腰椎间盘突出症的诊断价值

目的：介绍与验证一种反映腰椎间盘突出伴单侧坐骨神经痛的体征——模特征。方法：选取72例经腰椎MRI证实有腰椎间盘突出（L4，532例，L5／S1 40例）并伴单侧坐骨神经痛的患者，男49例，女23例，年龄32～68岁，平均50．7岁。每例患者人院当日由两位医师间隔2h分别检查，患者背对检查者，嘱其取最能缓解坐骨神经痛的站立姿势，若患者出现患侧屈髋屈膝、骨盆倾向患侧的姿势，记为“模特征阳性”，否则记为“模特征阴性”。同时行直腿抬高试验（SLR），阳性患者记录诱发下肢放射痛的最小角度。结果：70例患者两检查者结果完全相同，其中阳性60例，阴性10例，敏感性为85．7％；仅2例患者两检查者结果不一致，重复性97．2％。SLR均为阳性。结论：模特征是诊断伴单侧坐骨神经痛腰椎间盘突出症的简单、敏感的临床体征。

A systematic review and meta-analysis of biological treatments targeting tumour necrosis factor α for sciatica

Purpose

Systematic review comparing biological agents, targeting tumour necrosis factor α, for sciatica with placebo and alternative interventions.

Methods

We searched 21 electronic databases and bibliographies of included studies. We included randomised controlled trials (RCTs), non-RCTs and controlled observational studies of adults who had sciatica treated by biological agents compared with placebo or alternative interventions.

Results

We pooled the results of six studies (five RCTs and one non-RCT) in meta-analyses. Compared with placebo biological agents had: better global effects in the short-term odds ratio (OR) 2.0 (95 % CI 0.7–6.0), medium-term OR 2.7 (95 % CI 1.0–7.1) and long-term OR 2.3 [95 % CI 0.5 to 9.7); improved leg pain intensity in the short-term weighted mean difference (WMD) −13.6 (95 % CI −26.8 to −0.4), medium-term WMD −7.0 (95 % CI −15.4 to 1.5), but not long-term WMD 0.2 (95 % CI −20.3 to 20.8); improved Oswestry Disability Index (ODI) in the short-term WMD −5.2 (95 % CI −14.1 to 3.7), medium-term WMD −8.2 (95 % CI −14.4 to −2.0), and long-term WMD −5.0 (95 % CI −11.8 to 1.8). There was heterogeneity in the leg pain intensity and ODI results and improvements were no longer statistically significant when studies were restricted to RCTs. There was a reduction in the need for discectomy, which was not statistically significant, and no difference in the number of adverse effects.

Conclusions

There was insufficient evidence to recommend these agents when treating sciatica, but sufficient evidence to suggest that larger RCTs are needed.

破裂型椎间盘突出动物模型中自身免疫反应的实验研究

目的:从动物实验的角度探讨破裂型椎间盘突出动物模型中的自身免疫反应.方法:20只SD大鼠分为两组,实验组采用自体髓核移植于坐骨神经旁的方法建立破裂型椎间盘突出动物模型(坐骨神经痛模型);对照组大鼠手术方法同实验组,但不放置髓核.术前及术后1、2、3周时采用爬坡实验及后肢机械缩爪阈值测定评估大鼠造模前后后肢运动能力及痛觉过敏的变化.术后3周时处死动物应用透射比浊法检测大鼠血清中免疫球蛋白IgG、IgM的含量,ELISA法测定血清中TNF-α、IL-6、IL-12的含量;采用免疫组化染色观察移植髓核中抗原抗体复合物沉积情况;应用BCA蛋白定量法观察坐骨神经中磷脂酶A2(PLA2)的活性.结果:所有大鼠模型建立前爬坡试验结果均为Ⅳ级,造模后对照组爬坡试验仍为Ⅳ级,实验组在造模后1、2及3周时爬坡试验均为Ⅲ级.实验组大鼠造模后1、2、3周时的后肢机械缩爪阈值分别为67.2±8.4、41.3±5.2及40.7±5.3mmHg,较术前(90.4±5.0mmHg)及对照组明显降低(P＜0.01),出现较为明显的痛觉过敏.术后3周实验组大鼠血清中IgG含量4.98±0.96g/L及IgM含量1.45±0.37g/L较对照组(4.31±0.77g/L及0.79±0.35g/L)明显上升(P＜0.05);血清中TNF-α、IL-6、IL-12的含量(205.77±46.32pg/L,186.4±87.3pg/L,69.23±27.46pg/L)较对照组(11.01±2.53pg/L,85.0± 13.2pg/L,21.65±11.93pg/L)均明显升高(P＜0.05).实验组大鼠移植髓核中出现抗原抗体复合物阳性沉积,阳性率为80％,明显高于对照组(P＜0.01);其坐骨神经中PLA2活性为0.0766±0.0039μmoL/(min·L),较对照组0.0006±0.0010μmoL/(min·L)明显升高(P＜0.05).结论:破裂型椎间盘突出动物模型中存在着由移植髓核引起的全身及局部异常的自身免疫反应,这可能是导致其疼痛的主要原因.     

Reliability of gadolinium-enhanced magnetic resonance imaging findings and their correlation with clinical outcome in patients with sciatica

Background contextGadolinium-enhanced magnetic resonance imaging (Gd-MRI) is often performed in the evaluation of patients with persistent sciatica after lumbar disc surgery. However, correlation between enhancement and clinical findings is debated, and limited data are available regarding the reliability of enhancement findings.PurposeTo evaluate the reliability of Gd-MRI findings and their correlation with clinical findings in patients with sciatica.Study designProspective observational evaluation of patients who were enrolled in a randomized trial with 1-year follow-up.Patients samplePatients with 6- to 12-week sciatica, who participated in a multicentre randomized clinical trial comparing an early surgery strategy with prolonged conservative care with surgery if needed. In total 204 patients underwent Gd-MRI at baseline and after 1 year.Outcome measuresPatients were assessed by means of the Roland Disability Questionnaire (RDQ) for sciatica, visual analog scale (VAS) for leg pain, and patient-reported perceived recovery at 1 year. Kappa coefficients were used to assess interobserver reliability.MethodsIn total, 204 patients underwent Gd-MRI at baseline and after 1 year. Magnetic resonance imaging findings were correlated to the outcome measures using the Mann-Whitney U test for continuous data and Fisher exact tests for categorical data.ResultsPoor-to-moderate agreement was observed regarding Gd enhancement of the herniated disc and compressed nerve root (kappa<0.41), which was in contrast with excellent interobserver agreement of the disc level of the herniated disc and compressed nerve root (kappa>0.95). Of the 59 patients with an enhancing herniated disc at 1 year, 86% reported recovery compared with 100% of the 12 patients with nonenhancing herniated discs (p=.34). Of the 12 patients with enhancement of the most affected nerve root at 1 year, 83% reported recovery compared with 85% of the 192 patients with no enhancement (p=.69). Patients with and without enhancing herniated discs or nerve roots at 1 year reported comparable outcomes on RDQ and VAS-leg pain.ConclusionsReliability of Gd-MRI findings was poor-to-moderate and no correlation was observed between enhancement and clinical findings at 1-year follow-up.

Pregabalin and gabapentin for the treatment of sciatica

Whilst pregabalin (PGB) and gabapentin (GBP) are both used to treat neuropathic pain, their relative role in sciatica is unclear. Our aim was to extensively review the roles of PGB and GBP in treating sciatica. The efficacy, side effects (SE) profile and cost of PGB and GBP in neuropathic pain states were reviewed with special reference to sciatica. Eleven articles matched the criteria: seven systematic reviews, one retrospective cross-sectional study, one placebo-controlled-crossover study, one randomized placebo-controlled double-blind study and one case report. GBP and PGB appeared to demonstrate comparable efficacy and SE. However, the amount and quality of evidence was low, and only indirect comparisons were available. Importantly, no direct “head-to-head” study existed. Globally, costs varied widely (by up to 31 times) and unpredictably (PGB cheaper than GBP, or vice versa). Formulary regulator rulings were globally disparate; however, many exclusively favoured the more expensive drug (whether GBP or PGB). No studies assessed PGB-GBP interchange. Weak evidence suggests that efficacy and SE with GBP and PGB are probably similar; however, firm conclusions are precluded. Despite weak data, and having cited minor titration, but definite cost, advantages, UK National Institute for Health and Clinical Excellence favoured PGB over GBP. Given that no evidence supports unhindered PGB-GBP interchange, neither drug should probably be favoured. Prospective “head-to-head” studies are urgently required to provide robust evidence-based knowledge for choice of GBP or PGB in sciatica.
