Impaired awareness of movement disorders in Parkinson’s disease

Background

This study analyzed the presence of awareness of movement disorders (dyskinesias and hypokinesias) in 25 patients with Parkinson’s disease (PD) and motor fluctuations (dyskinesias, wearing off, on–off fluctuations). Of the few studies that have dealt with this topic, none have analyzed the differences in the awareness of motor deficits by comparing the on and off states using motor scales and an extensive battery of tests to assess cognitive and behavioral functioning.

Methods

PD patients were compared on three different scales that we have devised to measure awareness of movement disorders: Global Awareness of Movement (GAM) Disorders, dyskinesia/hypo-bradykinesia rating scales.

Results

Data showed that PD patients had greater awareness and psychological suffering in the off state than in the on state. In particular, they were troubled by motor disabilities related to hypokinesias and had mood-related symptoms and a perception of disability in activities of daily living. Interestingly, patients only showed a selective reduction of awareness of movement disorders associated with executive functions and related to dyskinesias in the on state, compared to a preserved awareness of hypokinesias in the off state. On the contrary, no association with executive functions was found in the off state.

Conclusion

Our findings suggest that the dopaminergic overstimulation of mesocorticolimbic pathways may cause a dysfunction of prefrontal–subcortical connections related to the impaired insight.     

Contribution of temporal preparation and processing speed to simple reaction time in persons with Alzheimer’s disease and mild cognitive impairment

Temporal preparation was assessed in 15 Alzheimer’s disease (AD) patients, 20 persons with mild cognitive impairment (MCI) and 28 healthy older adults. Participants completed a simple reaction time task in which the preparatory interval duration varied randomly within two blocks (short versus long temporal window). Results indicated that AD and MCI patients had difficulty preparing for the shortest preparatory interval of the short temporal window. AD and MCI patients also had difficulty maintaining an optimal level of preparation up to 5 s within the short temporal window. These results suggest that AD and MCI patients might show difficulty preparing for rapidly occurring events and maintaining preparation over time. This phenomenon should be considered when using reaction time measures with such patients.     

Impaired emotion recognition in music in Parkinson’s disease

Music has the potential to evoke strong emotions and plays a significant role in the lives of many people. Music might therefore be an ideal medium to assess emotion recognition. We investigated emotion recognition in music in 20 patients with idiopathic Parkinson’s disease (PD) and 20 matched healthy volunteers. The role of cognitive dysfunction and other disease characteristics in emotion recognition was also evaluated.     

急性冠脉综合征患者合并抑郁障碍对生存质量的影响

为了了解急性冠脉综合征(ACS)患者合并抑郁障碍的现状及其对生存质量(QOL)的影响,对104名ACS患者应用一般情况调查表、HAD(d)、SF-36进行调查。结果显示31.73%的ACS患者合并抑郁障碍;ACS伴抑郁障碍SF-36各因子分均低于不伴抑郁障碍;HAD(d)总分与SF-36各因子分均呈负相关。因此ACS患者是抑郁障碍的易感人群,且抑郁障碍可降低ACS患者的QOL。     

2000年～2009年国内胃食管反流病误诊文献回顾分析

为探讨胃食管反流病(GERD)误诊现状、原因和对策,对2000年～2009年10年间国内公开发表的GERD误诊报道文献97篇进行回顾性分析。既往10年间共报道GERD误诊病例2629例,共涉及38个病种,其中最常见的误诊病种是冠心病/心绞痛(48.04%)、慢性咽炎(24.23%)、支气管炎(10.27%)、支气管哮喘(8.56%)。主要误诊原因是GERD非典型表现繁杂,非消化科医生缺乏相关知识,忽视相关鉴别诊断。心血管、耳鼻喉、呼吸科医生是强化GERD认识的重点人群。     

中药在心血管疾病中应用现状与反思

具有悠久历史的中医药在现代医学中有鲜明的时代特点。心血管疾病是现代社会严重威胁生命及健康的病患。本文总结分析了古老中药在现代心血管疾病中应用的现状,并深入分析其影响因素,从而提出扬长避短的未来心血管疾病应用中药的思路。     

青年颈心综合征避免误诊为冠心病的临床诊疗策略

通过对临床收集的187例青年(≤45岁)颈心综合征患者的临床资料进行分析。探讨青年颈心综合征临床误诊为冠心病的原因及避免误诊的诊疗策略。目的在于帮助临床医师对青年颈心综合征进行识别,注意如何与冠心病心绞痛相鉴别,对防止病情延误,尽早明确诊断积极治疗,排除冠心病,减少诊疗费用及避免冠脉造影的风险意义很大。     

冠心病多支血管病变完全血运重建的长期疗效观察

为分析冠心病多支血管病变(MVD)患者经皮冠状动脉介入治疗(PCI)进行完全血运重建术后长期的临床疗效,我们收集了2004年5月~2008年5月589例接受PCI的冠心病患者,其中实施完全性血运重建(CRV)461例(78.3%),不完全性血运重建(IRV)128例(21.7%),对比分析两组病例PCI术后随访1年以上的结果。结果显示IRV组患者中完全闭塞病变、3支血管病变的比例均高于CRV组(P0.01);CRV组PCI成功率明显高于IRV组(94.8%vs87.5%,P0.05)。提示多支冠状动脉病变完全性血运重建能够获得更好的长期临床疗效论。     

指动脉背侧支皮瓣在手指末节皮肤缺损治疗中的临床应用

分析指背动脉背侧支与其血管网联合供血滋养皮瓣在指末端皮肤缺损的修复中的应用效果。取中节手指固有动脉的背侧支为蒂血管,逆行切取指背皮瓣31例共35指,移植修补位于远端指间关节或其远端的皮肤缺损。若同时伴有骨、关节、肌腱等的损伤,则予以同期修复。本研究中最大切取皮瓣1.5cm×3.5cm,平均随访6±0.5个月(3至9个月),皮瓣成活率100%,皮瓣两点辨别觉9±0.2mm,95%的患者具有良好的指间关节活动能力。因此,指动脉背侧支皮瓣手术操作简单,术后成功率高且患者恢复效果好。     

重视终末期肾病患者的心理治疗

心理治疗在终末期肾病(ESRD)治疗中的作用非常重要,不但可缓解患者的心理压力,还可改善患者的生理障碍、减少并发症,因此重视对ESRD患者的心理治疗,可使患者保持良好的生理、心理状态,并能提高患者的生活质量,改善预后。
