Factors Affecting Recurrent Deep Vein Thrombosis after Pharmacomechanical Thrombolysis and Left Iliac Vein Stent Placement in Patients with Iliac Vein Compression Syndrome

PurposeThis study evaluated the factors affecting contralateral and ipsilateral recurrent deep vein thrombosis (DVT) after iliac vein stent placement in patients with iliac vein compression syndrome (IVCS).Materials and MethodsData from 130 patients (95 female patients) who underwent catheter-directed thrombolysis and stent placement for IVCS with left lower leg thrombosis at a single institution were retrospectively analyzed. Mean patient age was 69.0 ± 14.0 years old. Median follow-up was 14 months (range, 3–164 months). Anticoagulation therapy was prescribed for 6 months, followed by lifelong antiplatelet therapy. Multivariate logistic regression analysis was performed to evaluate the factors affecting the development of contralateral and ipsilateral recurrent DVT.ResultsSeven patients (5.4%) developed contralateral DVT (median, 26 months; range, 2–61 months), and 11 patients (8.5%) developed ipsilateral DVT (median, 1 month; range, 0–53 months). Stent location (odds ratio [OR], 11.564; 95% confidence interval [CI], 1.159–115.417) and in-stent thrombosis during follow-up (OR, 15.142; 95% CI, 1.406–163.119) were predictors of recurrent contralateral DVT. Thrombophilia (OR, 47.560; 95% CI, 2.369–954.711), remaining inferior vena cava filter (OR, 30.552; 95% CI, 3.495–267.122), and in-stent thrombosis during follow-up (OR, 82.057; 95% CI, 2.915–2309.848) were predictors of ipsilateral DVT.ConclusionsContralateral DVT occurs late and is associated with extension of the iliac vein stent to the inferior vena cava and in-stent thrombosis. Ipsilateral DVT occurs relatively early and is associated with thrombophilia, remaining inferior vena cava filter, and in-stent thrombosis.     

Convergent Reliability and Validity of the Questions About Behavioral Function and the Motivation Assessment Scale: A Replication Study

This study compared key psychometric properties of the Motivation Assessment Scale (MAS) and the Questions About Behavioral Function (QABF) and explored their convergent validity. Twenty adults with mental retardation and problem behaviors (aggression, self-injury, or property destruction) and 31 respondents participated. Test–retest reliability of the subscales in both scales was good to excellent (Cicchetti, D. V., 1994, Psychol. Assess. 6: 284–290), and—except for 1 QABF subscale—internal consistency was good considering the small number of items and the purpose of the scale. Consistent with some earlier studies, interrater reliability was less satisfactory with both scales falling only into the fair to good range.Correlations between functionally equivalent subscales were statistically significant and were generally higher than correlations between nonequivalent subscales. The QABF and the MAS were found to be comparable in terms of the assessed reliabilities, and both instruments appear to be measuring very similar constructs.

目的 观察神经电生理检测对腓总神经卡压的诊断价值。方法 对腓总神经卡压的临床特征及病因进行分析，并作神经传导速度和肌电图检测和分析。结果 21条患病神经中1条神经波形消失。其余有不同程度的传导速度减慢，尤其是跨腓骨小头段，波幅降低，传导时间延长，42块腓总神经支配的肌肉中有30块出现失神经电位。结论 神经电生理检查在腓总神经卡压的诊断中有重要意义。     

压力梯度长袜和间歇充气装置预防恶性肿瘤患者术后下肢深静脉血栓形成的效果

目的 观察单纯应用压力梯度长袜（CS）或与间歇充气装置（IPC）联合使用预防恶性肿瘤患者术后下肢深静脉血栓（DVT）形成的效果及可能的机制。方法 胸科、泌尿外科、肝胆外科恶性肿瘤根治手术患者240例，随机分为4组：对照组、单纯CS组、CS＋IPC全程组、CS＋IPC术后组，每组60例。术后3～8d内行双下肢深静脉超声检查，记录DVT例数及血栓发生部位（大腿或小腿）。随机选择对照组和CS＋IPC全程组各15例患者，分别于术前、切皮后2h及术后24h各采集外周静脉血2ml，测定D-二聚体（D-D）、纤溶酶原激活物抗原（tPA-Ag）、纤溶酶原激活物抑制物（PAI）、血管性血友病因子（vWF）、凝血酶原时间（PT）和活化部分凝血活酶时间（APTT）。结果 术后3-8d对照组、CS＋IPC全程组、CS＋IPC术后组和单纯CS组DVT发生率分别为49．3％、15．0％、23．3％和30．0％（P〈0．05）。所有发生DVT患者中，除CS组发现1例近端DVT外，其余均为远端DVT。发生DVT患者年龄、卧床时间、危险因素个数等与未发生血栓患者相比差异有统计学意义（P〈0．05）。凝血，纤溶指标：与对照组比较，切皮后2h，CS＋IPC全程组vWF升高，D-D、tPA-Ag降低（P〈0．05），术后24h对照组和cs＋IPC全程组间D—D、vWF、tPA-Ag及PAI差异无统计学意义。结论 CS＋IPC全程或术后使用均能降低高危患者术后DVT的发生，其中CS＋IPC全程使用预防效果最好，可能与IPC增加纤溶活性有关。

目的探讨锁定加压钢板(LCP)经肱骨前侧入路微创穿皮固定治疗肱骨干骨折的方法及疗效。方法2004年2月-2005年1月间,使用LCP经肱骨前侧入路微创穿皮固定治疗肱骨干骨折17例,男12例,女5例;年龄18-75岁(平均48岁)。根据AO分型:A型3例,B型10例,C型4例。结果经14-25个月(平均19．1个月)随访,17例患者全部愈合。骨折愈合时间为9-14周(平均11．3周)。末次随访时,肩关节前屈135°-180°(平均174°),后伸20°-40°(平均38°),外展70°-90°(平均87°);肘关节前屈115°-135°(平均133°),后伸-10°-0°(平均-1°);手臂肩残疾问卷表(DASH)评分6-44分(平均11分)。术后3例出现并发症:1例GustiloⅢB型开放性骨折发生浅表感染,经保守治疗后痊愈;1例术后出现一过性桡神经麻痹,3个月后症状完全消退;另有1例出现明显的肩肘关节功能障碍。无继发骨折移位及内固定物失效或断裂。结论LCP经肱骨前侧入路微创穿皮固定治疗肱骨干骨折可以提供稳定的固定,骨折愈合率较高,神经血管结构相对安全;更适合于粉碎性或骨质较差的肱骨干骨折。     

早期干预对高危儿在婴儿早期发育的影响

目的：探讨早期干预对高危儿在婴儿早期发育的影响。方法：采用自行设计的一套早期干预方法通过指导家长对实验组实施，分别在3个月、6个月时进行格体生长和行为发育的评估，另设对照组进行比较。结果：实验组和对照组在体重、身长、头围方面均无统计学差异，但实验组的5个能区行为发育商均值都高于对照组，除3个月的语言能区外，其余均有统计学差异。结论：早期干预在婴儿早期就能促进高危儿的行为发育，但对促进高危儿的体格生长无明显效果。     

Spinal epidural hematoma. Report of a case and review of the literature

We report the case of a thoracic epidural hematoma at the T7-T9 level which occurred after placement of spinal epidural catheter for continuous anaesthesia in acute pancreatitis. The male patient felt a sudden back pain after six days of successful analgesia and became paraplegic 24 hours afterwards. An emergency laminectomy and removal of the hematoma were performed; however, the patient recovered only incompletely.We discuss the clinical signs and symptoms of spinal epidural hematoma as well as its diagnostics and therapy. The controversial views from the literature concernings its etiology are critically reviewed.     

Fos Expression in the Rat Brain Following Vaginal-Cervical Stimulation by Mating and Manual Probing

Vaginal-cervical stimulation (VCS), provided by mating or manual probing, induces many reproductive behavioral and endocrine changes in female rats. These changes include an increase in lordosis duration, heat termination and pseudopregnancy. Electro-physiological and [¹⁴C]2-deoxy-D-glucose studies collectively show that neurons in the medial preoptic area, ventromedial hypothalamus and midbrain central gray respond to manual VCS. In the present study we immunocytochemically labeled brain sections for Fos, the protein product of the immediate early gene c-fos, to detect VCS-responsive neurons in hormone-primed animals receiving VCS by mating or manual probing. In Experiment 1, females receiving mounts and intromissions were compared to: 1) vaginally-masked females receiving mounts but no VCS, 2) females exposed to an intact anesthetized male or 3) females not exposed to males or the testing arena. Those animals receiving VCS showed a dramatic increase in the number of Fos-immunoreactive cells in the medial preoptic area, posterodorsal portion of the medial amygdala and bed nucleus of the stria terminalis, as well as the dorsomedial hypothalamus, ventromedial hypothalamus and midbrain central gray. These effects of VCS were confirmed in Experiment 2 in animals receiving manual vaginal-cervical probing. These findings extend previous electrophysiological and [¹⁴C]2-deoxy-D-glucose studies by providing evidence that additional brain areas respond to VCS by mating, as well as manual probing.
