Total Hip Arthroplasty in Ankylosing Spondylitis With Extension Contracture of Hips

Background

Despite significant pain relief following total hip arthroplasty (THA) in patients with ankylosing spondylitis, a small subset of patients presenting with extra-articular extension contracture of hips remains unsatisfied.

Clinical profile of ankylosing spondylitis patients in Togo

Aim of the workTo determine the clinical characteristics of ankylosing spondylitis (AS) in rheumatology wards in Togo. Patients and methods: The medical records of AS patients in four rheumatology wards in Togo were recorded from January 2000 to December 2019. Results: The study included 37 AS cases out of 35,304 rheumatic diseases patients’ files that were investigated over the preceding 20 years; accounting for 0.1% of hospital cases. Male predominance was noticed with a M:F ratio of 4.3. The mean age at disease onset was 29.6 ± 10.3 years and the mean duration of the symptoms was 9.5 ± 9.2 years. The clinical findings were dominated by spinal pain (91.9%). The main peripheral joints involvements were knees (48.6%) and ankles (35.1%) and the most frequent extra-articular features were ocular with conjunctivitis (13.5%) and uveitis (8.1%) respectively. Plain radiographs of the spine revealed syndesmophytes (45.9%) with bony ankylosis and bamboo spine (21.6%); and that of the pelvis showed sacroiliitis in 89.2%. The human leucocytic antigen (HLA B27) was positive in four cases. Non-steroidal anti-inflammatory drugs (NSAIDs) and sulfasalazine were the most commonly used drugs, respectively in 89.2% and 67.6% of patients. One patient was receiving biologic therapy. Conclusion: Ankylosing spondylitis is relatively rare in Togo. There is no particularity in the clinical features or imaging and laboratory findings. The diagnostic delay reflects the importance of the plain radiograph structural changes. NSAIDs and disease modifying anti-rheumatic drugs (DMARDs) are the cornerstone of the treatment due to their accessibility in Togo.     

人工全髋关节置换术治疗56例强直性脊柱炎的临床研究

[目的]探讨人工全髋关节置换术治疗强直性脊柱炎的疗效。[方法]对56例（98髋）强直性脊柱炎患者行人工全髋关节置换术，其中42例（76髋）进行了平均5．6（2．5～10．5）a的随访。[结果]至末次随访时，Harris评分由术前的平均26．8（4～51）分提高到了术后的平均85．2（55～94）分，优良率为89．5％。1例感染行Ⅱ期翻修；2例在扩髓时出现股骨颈或股骨距裂缝骨折，但未到达小粗隆以下，未予特殊处置；1例出现足下垂，术后3个月后恢复，1例深静脉血栓，余病例无假体松动、断裂以及脱位发生。异位骨化发生率9．2％（7髋），但对功能无明显影响。[结论]人工全髋关节置换术治疗强直性脊柱炎可以明显缓解髋关节疼痛，恢复关节功能，与其它病因的全髋关节置换术相比，并无较高的危险因素。

强直性脊柱炎患者外周血CD62P的表达

目的探讨剖宫产指征的变化情况，分析影响剖宫产率的因素。方法 回顾性分析1393例剖宫产患者的临床资料。结果2年的平均剖宫产率为66．7％，其中2004年的剖宫产率为59．9％，2005年的剖富产率为72．2％，差异有统计学意义（P〈0．05）。剖宫产率的主要影响因素依次为社会因素（29．43％）、胎儿宫内窘迫（25．13％）、胎位异常（9．62％）、巨大胎儿（7．25％）、中至重度妊娠高血压综合征（6．25％）。结论剖宫产率的上升不只是一个纯医学问题，社会因素使剖宫产指征相对扩大，只有合理掌握剖宫产指征，通过医患双方、社会的共同努力，才能更好地降低剖宫产率。     

基质金属蛋白酶和细胞因子在强直性脊柱炎骨破坏中的作用

强直性脊柱炎(ankylosing spondylitis,AS)是以中轴关节慢性炎症为主的原因不明的全身性免疫性疾病。其特点为几乎全部累及骶髂关节,常发生椎间盘纤维环及其附近韧带钙化和骨性强直,也可累及外周关节并造成关节软骨及骨的破坏,晚期可发生脊柱及外周关节强直、畸形以致严重功能受损[1]。所以我们必须强调重视AS骨质破坏发生机制的研究,有利于寻找有效药物,减少致残。1骶髂关节炎组织学研究较系统的骶髂关节炎组织学研究表明,AS的5个阶段不同程度存在滑膜炎、骨髓黏液样变、浅表软骨破坏、肌腱端炎、关节内纤维赘、新骨形成和骨性强直等众多病理表现;其中滑膜炎和软骨下骨髓黏液样变较肌腱端炎更能合理解     

HLA-B*27 subtyping by PCR-RFLP in Spanish patients with ankylosing spondyiitis

Abstract: We describe the use of restriction analysis on PCR-amplified DNA for detecting all B*27 subtypes except B*2710 and B*2711 (i.e. from B*2701 to B*2709). After detecting B*27 by Sty I, double digestions consisting of Sty I plus another informative enzyme led to subtype assignment. We used mismatched primers to create restriction sites when necessary. The method avoids group-specific amplifications and other laborious optimization procedures. It was successfully tested on a panel of well characterized cell lines covering different B*27 subtypes. Then, we studied a group of 57 ankylosing spondyiitis patients and 746 controls from the south of Spain. B*27 showed a very strong association with the disease (OR=211.27, P=\0˜7). B*2702 and B*2705 distribution in controls (20% and 77.1%, respectively) differed from previously reported data in the Spanish population. We unexpectedly found the B*2707 allele in our population (one control).     

布氏杆菌性脊柱炎临床影像学表现及外科治疗

[目的]探讨布氏杆菌性脊椎炎的临床表现、影像学特点与外科治疗，以便提高该病的临床诊断和治疗水平。[方法]本组16例均行X线摄片并行CT检查，病灶分布腰椎多于胸椎，其中L4发病率最高，其中7例行MRI检查；16例血清试管凝集法滴度均大于1：160，虎红平板凝集试验阳性，酶联免疫吸附试验检查特异性抗体IgM、IgG阳性，11例作病原学检查。[结果]14例入院前临床、X线及CT误诊为脊柱结核，误诊率87．5％；经MRI扫描误诊5例，误诊率71．43％；本组16例入院确诊后，在药物治疗基础上，2例采取介入方法，7例采取手术病灶清除，病理符合布氏杆菌性脊椎炎的细胞学表现。本组仅12例（包括手术8例）进行随访1～2年，痊愈10例，好转2例，愈后无复发。[结论]布氏杆菌性脊椎炎临床与影像学具有特征性表现；正确选择微创术和手术病灶清除术可以缩短疗程，减少并发症，提高治愈率；无论手术还是非手术治疗，长期、足量、联合、多途径敏感抗生素的应用是治疗和防止本病复发的最主要和最可靠方法。     

强直性脊柱炎股骨近段形态学改变对全髋关节置换术假体选择的意义

目的分析强直性脊柱炎股骨近段的形态学改变,及其改变对全髋关节置换术假体选择的意义。方法1999年1月~2004年6月,将13例(16髋)强直性脊柱炎患者设为选择组,患者均已出现关节强直,需行全髋关节置换术。另16例(19髋)为对照组,为非强直性脊柱炎患者而拟行全髋关节置换术。两组患者均摄髋关节正侧位X线片,测量Singh指数、髓腔张开指数、皮质形态指数及皮质骨指数,并进行统计学分析。结果选择组Singh指数、髓腔张开指数及皮质形态指数分别为3.81±0.54、2.63±0.41及2.02±0.38,对照组分别为4.63±0.62、3.03±0.27及2.76±0.28,两组比较差异均有统计学意义(P<0.05)。选择组皮质骨指数为1.69±0.69,对照组为2.12±0.24,两组比较差异无统计学意义(P>0.05)。选择组患者髓腔呈烟囱型10例13髋,普通型3例3髋;对照组烟囱型3例3髋,普通型13例16髋。结论强直性脊柱炎的全髋关节置换术应采用骨水泥型人工关节假体,并根据患者髓腔形态使用定制型骨水泥假体,以达到更好的近段固定效果。对于有严重骨质疏松者应按关节翻修术处理。
