Acute Claudication caused by Angio-Seal Closure Devices: a Report of Four Cases

Femoral artery closure devices are increasingly used after percutaneous arterial interventions to obtain hemo-stasis at the puncture site. Their efficacy and advantages in patient comfort are established. Nevertheless they can cause their own specific complications. In a five month’s period we had to treat four patients with sudden onset invalidating claudication after the use of an Angio-Seal closure device. Malpositioning of the device led to the ischemic complications. We describe and illustrate the pre-and peroperative findings and the treatment. Interventionalists should monitor and register ischemic complications following the use of puncture site closure devices in order to try and minimize these. The occurrence of few serious complications can outweigh the relative small benefits these devices offer.     

Gastroduodenal Artery Pseudoaneurysm Ruptured in the Common Bile Duct

A pseudoaneurysm of the gastroduodenal artery (GDA) is the rarest splanchnic artery aneurysm, comprising fewer than 10% of these lesions. Bleeding into the gastrointestinal tract is the most rapidly fatal complication of an arterial visceral pseudoaneurysm, affecting 4–10% of patients. We present an unusual case of a GDA pseudoaneurysm that ruptured in the common bile duct, and that was successfully treated by partial resection and hepatic artery reconstruction. The postoperative evolution was favourable and the CT performed six months later disclosed the absence of a vascular tumour.     

Neurometabolic profiles of the substantia nigra and striatum of MPTP‐intoxicated common marmosets: An in vivo proton MRS study at 9.4 T

Given the strong coupling between the substantia nigra (SN) and striatum (STR) in the early stage of Parkinson's disease (PD), yet only a few studies reported to date that have simultaneously investigated the neurochemistry of these two brain regions in vivo, we performed longitudinal metabolic profiling in the SN and STR of 1‐methyl‐1,2,3,6‐tetrahydropyridine (MPTP)‐intoxicated common marmoset monkey models of PD (n = 10) by using proton MRS (¹H–MRS) at 9.4 T. T₂ relaxometry was also performed in the SN by using MRI. Data were classified into control, MPTP_2weeks, and MPTP_6‐10 weeks groups according to the treatment duration. In the SN, T₂ of the MPTP_6‐10 weeks group was lower than that of the control group (44.33 ± 1.75 versus 47.21 ± 2.47 ms, p < 0.05). The N‐acetylaspartate to total creatine ratio (NAA/tCr) and γ‐aminobutyric acid to tCr ratio (GABA/tCr) of the MPTP_6‐10 weeks group were lower than those of the control group (0.41 ± 0.04 versus 0.54 ± 0.08 (p < 0.01) and 0.19 ± 0.03 versus 0.30 ± 0.09 (p < 0.05), respectively). The glutathione to tCr ratio (GSH/tCr) was correlated with T₂ for the MPTP_6‐10 weeks group (r = 0.83, p = 0.04). In the STR, however, GABA/tCr of the MPTP_6‐10 weeks group was higher than that of the control group (0.25 ± 0.10 versus 0.16 ± 0.05, p < 0.05). These findings may be an in vivo depiction of the altered basal ganglion circuit in PD brain resulting from the degeneration of nigral dopaminergic neurons and disruption of nigrostriatal dopaminergic projections. Given the important role of non‐human primates in translational studies, our findings provide better understanding of the complicated evolution of PD.

Contemporary Psychotherapy Research: Implications for Substance Misuse Treatment and Research

This article provides an overview of the major findings of psychotherapy research and discusses the possible implications of these findings for substance user treatment researchers and practitioners. While the centrality of relationship for human change processes was historically understood, twentieth century research tended to see relationship and person variables as secondary to operationalized “mechanisms of action” unique to particular psychotherapies. Interestingly, recent meta-analytic investigations have uncovered the weakness of randomized controlled trials (RCT) comparison investigations that have, until recently, represented the “gold standard” for the field. There has been a resurgent interest in the “common factors” that appear to be important across many effective psychotherapies. In addition, psychiatric anthropologists have contributed important information about the problems of client noncompliance with mental health treatment that parallel quantitative investigations. Substance misuse researchers have also found that client characteristics, especially clients' readiness to engage treatment, are important to investigate. The importance of the “therapeutic alliance” and the characteristics of clients and clinicians have become central areas for study, rather than variables to be controlled or excluded. Emphasis on these factors may represent the future for research in psychotherapy and substance user treatment, especially if researchers and community practitioners can join together to overcome methodological feasibility and dissemination problems that plague effectiveness research. However, the continued attractiveness of comparative studies and treatment efficacy studies may represent longstanding epistemological assumptions and responses to economic incentives that will be difficult to challenge.     

手术室护士实施综合性护理干预对腹腔镜胆总管切开探查取石术患者心理状况及并发症的影响

目的探讨手术室护士实施综合性护理干预对腹腔镜胆总管切开探查取石术患者的心理状况及并发症的影响。方法全部入选病例均为本院2013年1月~2014年3月期间择期行腹腔镜胆总管切开探查取石术患者,根据护理方法不同分为干预组和对照组各40例,两组患者均由手术室护士进行围术期护理,其中对照组实施常规护理及随机对症护理,干预组手术室护士着重实施包括心理干预、T形管的护理、并发症的护理等综合性护理干预措施,比较两组患者术前和术后的焦虑心理状况SAS评分、两组患者的术中出血量、手术时间、术后排气时间、住院时间及两组患者的并发症情况。结果干预组和对照组的SAS评分术后与术前比较差异有统计学意义(P<0.05),且干预组患者术后的SAS评分显著低于对照组(P<0.05)。干预组患者的术中出血量、术后排气时间与对照组比较,差异有统计学意义(P<0.05),干预组患者的手术时间、住院时间略短于对照组,组间比较差异无统计学意义(P>0.05)。两组均未发生胆道狭窄,干预组患者术后发生胆石残留1例,术后出血1例,其并发症发生率达5.0%,显著低于对照组患者术后的并发症发生率27.5%(P<0.05)。其中干预组患者术后出血的发生率达2.5%,显著低于对照组的12.5%(P<0.05)。结论手术室护士对腹腔镜胆总管切开探查取石术患者通过实施综合性护理干预,有利于减轻患者的焦虑心理,减少并发症的发生率,从而明显提高手术治疗效果。
