Lymphedema is an uncommon extra-articular complication of rheumatoid arthritis (RA), but it can also be associated with psoriatic arthritis (PsA), although rarely. While lymphedema associated with RA is well characterized in literature, only few cases have been described among patients with PsA. Upper limbs are the most common sites involved, with asymmetric pattern, even if some patients may present lower limb oedema, or progressive bilateral oedema. Chronic established lymphoedema deriving from lymphatic vessel dysfunction should be clearly distinct from inflammatory distal pitting edema (IDPE), resulting from tenosynovitis and frequently encountered in PsA. In contrast to lymphedema, the latter condition generally presents an excellent response to steroid therapy, therefore it is essential to recognize the exact etiology of lymphoedema to approach the correct treatment. Here we report a case of lower limbs lymphedema in PsA and review the available literature upon the topic.
淋巴水肿是类风湿性关节炎(RA)的一种罕见的关节外并发症,但它也可能与银屑病关节炎(PsA)相关,尽管很少。虽然淋巴水肿与类风湿性关节炎相关在文献中有很好的特征,但在PsA患者中只有少数病例被描述。上肢是最常见的受累部位,且不对称分布,即使部分患者可出现下肢水肿或进行性双侧水肿。由淋巴管功能障碍引起的慢性淋巴水肿应与炎性远端凹陷性水肿(IDPE)明确区分,后者由腱鞘炎引起,在PsA中常见。与淋巴水肿相反,后一种情况通常对类固醇治疗有很好的反应,因此认识淋巴水肿的确切病因以采取正确的治疗是至关重要的。在这里,我们报告一个病例的下肢淋巴水肿在PsA和回顾现有文献的主题。

Progressive Neurological Diseases (PND) and Chronic Cerebrospinal Venous Insufficiency (CCSVI) and Multiple Sclerosis (MS) have two terms in common: “progressive and chronic” and shortly mean that there is no definitive therapy, at the moment. The clinical aspects are built on symptoms, upon which the definition of “progression” is based and hence classified. Changement and worsening of symptoms, allow classification of the disease and adjustments are effectively an “up to date” of the disease itself. We here resume the ten-year survey of 482 Multiple Sclerosis (MS)-affected patients (314 females, 168 males; mean age =37.8), classified by their Neurology Physicians as Relapse-Remitting (RR), according to the Kurtzke Expanded Disability Status Scale (EDSS), monitoring the parallel presence of CCSVI with clinical MS progression. Results are present from two homogeneous Relapse-Remitting MS groups of patients divided as “treated and non-treated for CCSVI” with vein angioplasty (vPTA). Furthermore, a Patient’s self-classification based upon symptoms in presence of CCSVI, up to now never implemented, was developed on the basis of both clinical and Duplex vascular issues.  
进行性神经系统疾病(PND)、慢性脑脊髓静脉功能不全(CCSVI)和多发性硬化症(MS)有两个共同的术语:“进行性和慢性”,这意味着目前没有明确的治疗方法。临床方面以症状为基础,“进展”的定义以此为基础,并据此分类。改变和恶化的症状,允许疾病的分类和调整是有效的疾病本身的“最新”。我们在此恢复对482例多发性硬化症(MS)患者的十年调查(女性314人,男性168人;平均年龄=37.8岁),由他们的神经内科医生根据Kurtzke扩展残疾状态量表(EDSS)将其分类为复发缓解型(RR),监测CCSVI与临床MS进展的平行存在。结果来自两个均质复发缓解型MS患者组,分为静脉血管成形术(vPTA)“治疗和未治疗CCSVI”。此外,基于存在CCSVI的症状的患者自我分类,迄今尚未实施,是在临床和双侧血管问题的基础上开发的。

What are the ideal characteristics of a venous stent? 静脉支架的理想特性是什么?
Pub Date : 2021-06-18 DOI: 10.4081/vl.2021.9739

Historically, the stents used in the venous system were not dedicated scaffolds. They were largely adapted arterial stents. An essential feature of a venous stent is compliance, in order to adapt its crosssectional area to the vein. It should also be crush resistant, corrosion resistant and fatigue resistant. The material should be radiopaque, for follow-up. Another characteristic of the ideal venous stent is flexibility, to adapt its shape to the vein, not vice versa. The scaffold should be uncovered too, in order to avoid the occlusion of collaterals. The ideal venous stent should not migrate, so it is necessary a large diameter and a long length. The radial force is important to prevent migration. However, current stents derived from arterial use display high radial force, which could affect the patency of the thin venous wall. Alternatively, if the stent has an anchor point, that permits a passive anchoring, the radial force required to avoid migration will be lower. Dedicated venous stents were not available until very recently. Furthermore, there is a preclinical study about a new compliant nitinol stent, denominated Petalo CVS. Out of the commonest causes of large veins obstruction, dedicated venous stent could also treat other diseases described more recently, such as the jugular variant of the Eagle syndrome, JEDI syndrome and jugular lesions of the chronic cerebrospinal venous insufficiency that result unfavorable for angioplasty according to Giaquinta classification.
历史上,用于静脉系统的支架不是专用支架。它们很大程度上是动脉支架。静脉支架的一个基本特征是顺应性,以便使其横截面积适应静脉。它还应该耐压、耐腐蚀和耐疲劳。该材料应不透光,以便随访。理想的静脉支架的另一个特点是灵活性,使其形状适应静脉,而不是相反。支架也要揭开,以免络闭塞。理想的静脉支架不应移位,因此需要大直径、长长度的支架。径向力对防止偏移很重要。然而,目前由动脉使用的支架显示高径向力,这可能影响薄静脉壁的通畅。或者,如果支架有一个锚点,允许被动锚定,避免迁移所需的径向力将更低。专用静脉支架直到最近才出现。此外,还有一项关于新型顺应性镍钛合金支架的临床前研究,命名为Petalo CVS。除了大静脉阻塞最常见的原因外,专用静脉支架还可以治疗最近描述的其他疾病,如Eagle综合征的颈静脉变异型、JEDI综合征和慢性脑脊髓静脉功能不全的颈静脉病变,这些疾病根据Giaquinta分类不利于血管成形术。

In this proof-of-concept study the impact of central venous pressure (CVP) on internal jugular veins cross-sectional area (CSA) and blood flow time-average velocity (TAV) was evaluated in eight subjects, with the aim of understanding the drivers of the jugular venous pulse. CVP was measured using a central venous catheter while CSA variation and TAV along a cardiac cycle were acquired using ultrasound. Analysis of CVP, CSA and TAV time-series signals revealed TAV and CSA to lag behind CVP by on average 0.129 s and 0.138 s, with an inverse correlation between CSA and TAV (r= –0.316). The respective autocorrelation signals were strongly correlated (mean r=0.729-0.764), with mean CSA periodicity being 1.062 Hz. Fourier analysis revealed the frequency spectrums of CVP, TAV and CSA signals to be dominated by frequencies at approximately 1 and 2 Hz, with those >1 Hz greatly attenuated in the CSA signal. Because the autocorrelograms and periodograms of the respective signals were aligned and dominated by the same underlying frequencies, this suggested that they are more easily interpreted in the frequency domain rather than the time domain.
在这项概念验证研究中,我们评估了8名受试者的中心静脉压(CVP)对颈内静脉横截面积(CSA)和血流时间平均速度(TAV)的影响,目的是了解颈静脉脉冲的驱动因素。使用中心静脉导管测量CVP,同时使用超声获得CSA变化和TAV沿心周期。CVP、CSA和TAV时间序列信号分析显示,TAV和CSA平均滞后于CVP 0.129 s和0.138 s, CSA与TAV呈负相关(r= -0.316)。各自相关信号呈强相关(平均r=0.729-0.764),平均CSA周期为1.062 Hz。傅里叶分析表明,CVP、TAV和CSA信号的频谱以约1 Hz和2 Hz的频率为主,其中>.1 Hz的频率在CSA信号中明显衰减。由于各自信号的自相关图和周期图由相同的底层频率对齐并占主导地位,这表明它们在频域比在时域更容易解释。

Contrast-induced encephalopathy (CIEP) is a rare complication after endovascular therapy. The etiology of CIEP is still a matter of debate. We present a rare occurrence of CIEP in a known hypertensive and type 2 diabetic patient after endovascular coiling of cerebral aneurysm with oculomotor nerve palsy. A 68-year old female presented with seven days history of headache and left ptosis or blepharoptosis with mild mydriasis. The headaches were localized mainly at the left side of the nose, orbit, and upper forehead while the left ptosis was associated with blurred vision. Computed tomography angiography revealed an aneurysm in between the C4 segment of the left internal carotid artery (ICA) and the bifurcation of the left posterior communicating artery. Digital subtraction angiography further confirmed the aneurysm. We used the transarterial approach to assess the aneurysm and subsequent coiling. Iohexol (Omnipaque) contrast agent was used during the endovascular procedure. The patient’s condition deteriorated into acute confusion state with cardinal symptomology of CIEP immediately after the operation. Computed tomography scan revealed cortical contrast enhancement in the vascular territory of the ICA as well as edema. Her symptomatology resolved 48 hours after treated with anticonvulsants, intracranial pressure reduction and hydration. Chronic hypertension as well as type 2 diabetics may be critical predisposing factors to CIEP. CIEP should be suspected in patients presenting with acute confusion state after endovascular therapy. Massive edema with ischemic brain changes in white matter of the brain before endovascular procedure should rise suspicion of CIEP. Introduction Contrast-induced encephalopathy (CIEP) is a rare complication after endovascular therapy.1-5 The precise etiological mechanisms via which this occur is still a matter of debate.2,4 Nevertheless, osmotic disruption of the blood-brain barrier (BBB) arising from repeated contrast injections into a single vessel has been speculated as a cause of this complication.3,4,6 Chronic hypertension, transient ischemia attack, compromised cerebral autoregulation, renal failure, enormous contrast volumes, selective vertebralbasilar arteriography (VAG) and male gender have been implicated as predisposing factors of CIEP.5,7-10 The symptomatology of CIEP often commence during the procedure but become apparent few hours after the procedure.5 Most symptoms are typically self-limiting, resolving within 2-4 days of onset.3,11,12 Nevertheless, full recovery may take as long as few weeks in a few patients.3,12 Anomalous cortical contrast enhancement with mild to severe edema, subarachnoid contrast enhancement, as well as striatal contrast enhancement are the typical postprocedural CT findings.2,9,12 Adequate hydration with intravenous crystalloids as well as anticonvulsants are the supportive treatment modalities for this post procedural complication.5,13 The observation of CIEP in a known hypertensi
对比剂诱发的脑病(CIEP)是一种罕见的血管内治疗并发症。CIEP的病因仍有争议。我们报告一例罕见的高血压和2型糖尿病患者在脑血管内缠绕脑动脉瘤并发动眼神经麻痹后发生CIEP。女,68岁,头痛,左上睑下垂,轻睑下垂7天。头痛主要发生在鼻部左侧、眼眶和前额上部,左侧上睑下垂伴视力模糊。计算机断层血管造影显示左侧颈内动脉C4段和左侧后交通动脉分叉之间有一动脉瘤。数字减影血管造影进一步证实了动脉瘤。我们采用经动脉入路评估动脉瘤和随后的缠绕。血管内手术期间使用碘己醇(Omnipaque)造影剂。术后患者病情立即恶化为急性神志不清,主要症状为CIEP。计算机断层扫描显示ICA血管区域皮质对比增强以及水肿。经抗惊厥药、降低颅内压及水合治疗48小时后症状消失。慢性高血压和2型糖尿病可能是诱发CIEP的关键因素。血管内治疗后出现急性神志不清的患者应怀疑CIEP。血管内手术前脑白质大量水肿伴缺血性脑改变应引起对CIEP的怀疑。对比剂诱发脑病(CIEP)是一种罕见的血管内治疗并发症。1-5发生这种情况的确切病因机制仍有争议。然而,由于在单血管内反复注射造影剂而引起的血脑屏障(BBB)的渗透性破坏已被推测为该并发症的原因。3,4,6慢性高血压、短暂性缺血发作、大脑自身调节功能受损、肾功能衰竭、造影剂体积过大、选择性椎基底动脉造影(VAG)和男性均被认为是诱发CIEP的因素。5,7-10 CIEP的症状通常在手术过程中开始,但在手术后几小时内变得明显大多数症状通常是自限性的,在发病2-4天内消退。3,11,12然而,少数患者的完全康复可能需要长达几周的时间。3,12术后典型的CT表现为皮质异常增强伴轻度至重度水肿、蛛网膜下腔增强及纹状体增强。2,9,12静脉注射晶体类药物和抗惊厥药物是治疗这种术后并发症的支持性治疗方式。5,13在已知的高血压和2型糖尿病患者血管内动脉瘤盘绕术后观察到CIEP非常罕见,尚未见文献报道。我们报告一例高血压和2型糖尿病合并左动眼神经麻痹(OMNP)的脑动脉瘤血管内缠绕术后发生CIEP的病例。

We herein used MAZ51 to inhibit lymphangiogenesis and aimed to clarify the effect of inhibition of lymphangiogenesis on wound healing. BALB/c male mice were divided into two groups: the control group which was injected the dimethyl sulfoxide (DMSO), the experiment group was injected MAZ51 in the DMSO. All wounds were observed for 15 days and the wound areas were measured. Tissue samples were harvested on day 3, 7, 9, 11, 13 and 15, and subjected to immunostaining of blood vessels and lymphatic vessels. There are no significant differences between two groups in the wound area, the number of blood vessels and lymphatic vessels. The number of blood vessels peaked on day 7 in both groups as with previous studies, while the number of lymphatic vessels peaked on 13 or 15 in both groups. This result revealed delayed lymphangiogenesis in comparison with previous studies. The wound healing process in the control and experiment groups were similar, but both groups seemed delayed lymphangiogenesis comparing with previous studies. Injections of MAZ51 or/and DMSO did not affect angiogenesis, while they may affect lymphangiogenesis.
我们使用MAZ51抑制淋巴管生成,旨在阐明抑制淋巴管生成对伤口愈合的影响。将BALB/c雄性小鼠分为两组:对照组注射二甲亚砜(DMSO),实验组注射DMSO中的MAZ51。观察创面15 d,测量创面面积。于第3、7、9、11、13和15天采集组织样本,对血管和淋巴管进行免疫染色。两组在创面面积、血管数量、淋巴管数量上均无明显差异。与以往的研究一样,两组的血管数量在第7天达到峰值,而两组的淋巴管数量在第13或15天达到峰值。与以前的研究相比,该结果显示淋巴管生成延迟。对照组和实验组的创面愈合过程相似,但与以往研究相比,两组均出现淋巴管生成延迟。注射MAZ51或/和DMSO不影响血管生成,但可能影响淋巴管生成。

Injections of MAZ51 or/and DMSO did not affect angiogenesis, while they may affect lymphangiogenesis.","PeriodicalId":421508,"journal":{"name":"Veins and Lymphatics","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117198181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Venous ulcers represent the most frequent ulcers and have a high clinical and socioeconomic significance. Nevertheless, pending questions remain on epidemiology, genetic and biomolecular mechanisms, contraindications and risk factors of compression therapy, role of pharmacological therapy. Overall prevalence in the range of 1-2% and point prevalence of 0.08-0.6% can be reduced if risk factors are identified and treated early. In this context, analysis of factor XIII and hemocromatosis gene polymorphisms, with the C282Y and H63D variants, may be of great importance. Also MMP12 gene polymorphism and the imbalance between matrix metalloproteinases and their tissue inhibitors are able to impair wound healing via deleterious degradation process of extra-cellular matrix. From a therapeutic point of view, conflicting recommendations exist on relative contraindications, risks and adverse events of compression therapy. Some studies showed that the administration of pentoxyphilline, Micronized purified flavonoid fraction (MPFF) and sulodexide was effective in accelerating ulcer healing, but there is no data on the duration of treatment, recurrence rates and cost-effectiveness relation-
静脉溃疡是最常见的溃疡,具有很高的临床和社会经济意义。然而,在流行病学、遗传和生物分子机制、压迫治疗的禁忌症和危险因素、药物治疗的作用等方面仍存在有待解决的问题。如果及早发现和治疗危险因素,可以降低1-2%的总患病率和0.08-0.6%的点患病率。在这种情况下,分析因子XIII和血色素沉着病基因多态性,与C282Y和H63D变异,可能是非常重要的。此外,MMP12基因多态性以及基质金属蛋白酶与其组织抑制剂之间的不平衡能够通过细胞外基质的有害降解过程影响伤口愈合。从治疗的角度来看,关于压迫治疗的相对禁忌症、风险和不良事件存在矛盾的建议。一些研究表明,己氧基菲林、微粉纯化类黄酮提取物(MPFF)和苏洛地特对加速溃疡愈合有效,但没有关于治疗时间、复发率和成本-效果关系的数据
