Abstract

OBJECTIVES:The treatments described for spinal synovial cysts range from percutaneous puncture to arthrodesis. There is a fear of postoperative instability after surgical resection of cysts, mainly when they are associated with degenerative spondylolisthesis. The objective of the article is to address the postoperative instability and recurrence rate of the symptoms after microsurgery without fusion. METHODS:We report a consecutive series of 50 patients with lumbar synovial cysts operated on with microsurgery without arthrodesis. Functional status was assessed postoperatively by the MacNab success scale and by self-assessment using the Weiner scale, the 36-item short-form health survey (SF-36), and the Oswestry scale. The presence of preoperative and postoperative instability was determined with static and dynamic lumbar spine X-rays before surgery and in the last follow-up at 2 years to evaluate the presence of spondylolisthesis before and after surgery. Facet inclination angle and stage of disc degeneration at the level of the cysts were evaluated. Disc degeneration was defined by the modified Pfirrmann grading system. RESULTS:The mean Oswestry index was 12 ± 12.6% (median 8, 0-53). Based on the MacNab scale, 98% were considered excellent and good. The Weiner scale showed that low back pain was present in 16% of patients postoperatively. There was significant improvement of leg strength and pain in 96% and 94%, respectively. Only 3 patients were reoperated on with late fusion. Total surgical resection was obtained in all cases, with a late fusion rate of only 6% and no recurrence at the operated site. CONCLUSIONS:The microsurgical treatment for synovial cysts without arthrodesis presented excellent and good results in the majority of cases. It is necessary to carry out prospective randomized studies to clarify the best therapeutic options.

摘要

目的: 脊柱滑膜囊肿的治疗方法从经皮穿刺到关节融合术。手术切除囊肿后害怕术后不稳定,主要是当它们与退行性滑脱相关时。本文的目的是解决显微外科手术不融合术后症状的不稳定和复发率。 方法: 我们连续报道了 50 例腰椎滑膜囊肿患者的显微外科手术,无关节融合术。术后通过MacNab成功量表评估功能状态,并使用Weiner量表、 36 项简明健康调查 (SF-36) 和Oswestry量表进行自我评估。术前和术后不稳定的存在通过术前和术后 2 年的静态和动态腰椎x线片来确定,以评估术前和术后是否存在滑脱。。在囊肿水平评估关节突倾角和椎间盘退变分期。椎间盘退变由改良的Pfirrmann分级系统定义。 结果: 平均Oswestry指数为 12 ± 12.6% (中位数 8,0-53)。根据MacNab量表,98% 被认为是优秀和良好的。Weiner量表显示术后 16% 的患者存在腰痛。腿部力量和疼痛的显著改善分别为 96% 和 94%。仅 3 例患者再次手术晚期融合。所有病例均获得手术全切除,晚期融合率仅为 6%,手术部位无复发。 结论: 无关节融合术的显微外科手术治疗滑膜囊肿,多数病例疗效良好。有必要进行前瞻性随机研究,以明确最佳治疗方案。

METHODS:OBJECTIVE:Patients with immune-mediated inflammatory diseases such as rheumatoid arthritis or systemic lupus erythematosus are at increased risk of cardiovascular disease. However, the cardiovascular risk of patients with primary Sjögren's syndrome (SS) remains poorly studied. We aimed to investigate the association between primary SS and cardiovascular morbidity and mortality. METHODS:We performed a systematic review of articles in Medline and the Cochrane Library and recent abstracts from US and European meetings, searching for reports of randomized controlled studies of cardiovascular morbidity and cardiovascular mortality in primary SS. The relative risk (RR) values for cardiovascular morbidity and mortality associated with primary SS were collected and pooled in a meta-analysis with a random-effects model by using Review Manager (Cochrane collaboration). RESULTS:The literature search revealed 484 articles and abstracts of interest; 14 studies (67,124 patients with primary SS) were included in the meta-analysis. With primary SS versus control populations, the risk was significantly increased for coronary morbidity (RR 1.34 [95% confidence interval (95% CI) 1.06-1.38]; P = 0.01), cerebrovascular morbidity (RR 1.46 [95% CI 1.43-1.49]; P < 0.00001), heart failure rate (odds ratio 2.54 [95% CI 1.30-4.97]; P < 0.007), and thromboembolic morbidity (RR 1.78 [95% CI 1.41-2.25]; P < 0.00001), with no statistically significant increased risk of cardiovascular mortality (RR 1.48 [95% CI 0.77-2.85]; P = 0.24). CONCLUSION:This meta-analysis demonstrates that primary SS is associated with increased cardiovascular morbidity, which suggests that these patients should be screened for cardiovascular comorbidities and considered for preventive interventions, in a multidisciplinary approach with cardiologists.

METHODS:OBJECTIVE:We aimed to evaluate the comparative risk of hospitalized infection among patients with rheumatoid arthritis (RA) who initiated abatacept versus a tumor necrosis factor inhibitor (TNFi). METHODS:Using claims data from Truven MarketScan database (2006-2015), we identified patients with RA ages ≥18 years with ≥2 RA diagnoses who initiated treatment with abatacept or a TNFi. The primary outcome was a composite end point of any hospitalized infection. Secondary outcomes included bacterial infection, herpes zoster, and infections affecting different organ systems. We performed 1:1 propensity score (PS) matching between the groups in order to control for baseline confounders. We estimated incidence rates (IRs) and hazard ratios (HRs) with 95% confidence intervals (95% CIs) for hospitalized infection. RESULTS:We identified 11,248 PS-matched pairs of patients who initiated treatment with abatacept and TNFi with a median age of 56 years (83% were women). The IR per 1,000 person-years for any hospitalized infection was 37 among patients who initiated treatment with abatacept and 47 in those who initiated treatment with TNFi. The HR for the risk of any hospitalized infection associated with abatacept versus TNFi was 0.78 (95% CI 0.64-0.95) and remained lower when compared to infliximab (HR 0.63 [95% CI 0.47-0.85]), while no significant difference was seen when compared to adalimumab and etanercept. The risk of secondary outcomes was lower for abatacept for pulmonary infections, and similar to TNFi for the remaining outcomes. CONCLUSION:In this large cohort of patients with RA who initiated treatment with abatacept or TNFi as a first- or second-line biologic agent, we found a lower risk of hospitalized infection after initiating abatacept versus TNFi, which was driven mostly by infliximab.

METHODS:OBJECTIVE:Reducing pain is one of the main health priorities for children and young people with juvenile idiopathic arthritis (JIA); however, some studies indicate that pain is not routinely assessed in this patient group. The aim of this study was to explore health care professionals' (HCPs) beliefs about the role of pain and the prioritization of its assessment in children and young people with JIA. METHODS:Semi-structured interviews were conducted with HCPs who manage children and young people with JIA in the UK (including consultant and trainee pediatric rheumatologists, nurses, physical therapists, and occupational therapists). Data were analyzed qualitatively following a framework analysis approach. RESULTS:Twenty-one HCPs participated. Analyses of the data identified 6 themes, including lack of training and low confidence in pain assessment, reluctance to engage in pain discussions, low prioritization of pain assessment, specific beliefs about the nature of pain in JIA, treatment of pain in JIA, and undervaluing pain reports. Assessment of pain symptoms was regarded as a low priority and some HCPs actively avoided conversations about pain. CONCLUSION:These findings indicate that the assessment of pain in children and young people with JIA may be limited by knowledge, skills, and attitudinal factors. HCPs' accounts of their beliefs about pain in JIA and their low prioritization of pain in clinical practice suggest that a shift in perceptions about pain management may be helpful for professionals managing children and young people with this condition.
