Bipolar disorders: treatment options and patient satisfaction

Functional recovery, the goal of treatment, has long been overlooked in the assessment of effectiveness of pharmacological treatments. However, with the recent shift in paradigm, from syndromal–symptomatic recovery to functional recovery, there appears to be a new interest in the definition and evaluation of functional recovery. Since functional recovery lags symptomatic recovery, sometimes by months or years, the attainment of functional recovery will be determined by both efficacy and long-term compliance. Quetiapine, due to its efficacy in both mania and depression, and effect on cognition may lead to improved functioning in patients with bipolar disorder.     

重型颅脑损伤的手术治疗

目的探讨重型颅脑损伤梯度减压的手术方法对预防术中脑膨出、降低死亡率及致残率的效果。方法对100例重型颅脑损伤患者采用分次减压手术方式及去骨瓣后，硬膜与颞肌筋膜瓣减张缝闭硬膜切口方法。结果40例脑肿胀患者术中脑嘭出6例占15．0％，死亡19例占47．5％；60例脑内血肿病人未发生脑膨出，死亡12例占20％。结论脑外伤后脑血管调节麻痹及血肿压迫继发脑水肿易造成脑膨出.术中分次减压降低了骨窗部位脑组织的顺应性，从而降低了局部的压力梯度，避免脑血管急性扩张，能有效防止脑膨出，降低死亡率及致残率。     

Bilateral Implantation of Centromedian‐Parafascicularis Complex and GPi: A New Combination of Unconventional Targets for Deep Brain Stimulation in Severe Parkinson Disease

Objectives. Traditional deep brain stimulation (DBS) at the subthalamic nucleus (STN) has proved to be efficacious on core Parkinsonian symptoms. However, very disabling l ‐dopa–induced abnormal involuntary movements (AIMs) and axial signs are slightly affected, suggesting that we target less conventional targets. Our candidates for DBS were the globus pallidus internus (GPi) plus the intralaminar thalamic complex (Pf or CM), given its extensive functional links with basal ganglia nuclei. Materials and Methods. The routine utilization of our innovative stereotactic apparatus allows us to implant, at the same time, both the CM‐Pf complex together with the GPi in six Parkinson disease patients. Both intraoperative and postoperative neurophysiologic assessments helped us recognize functional subregions while optimizing implantation of electrodes. Unified Parkinson disease rating scale (UPDRS) motor scores, AIMs, and freezing were carefully blindly evaluated for each condition. Results. A significant amelioration of UPDRS scores was achieved by simultaneous activation of both targets. CM‐Pf activation was only slightly effective in reducing rigidity and akinesia, but more efficacious on freezing. Not surprisingly, AIMs were peculiarly decreased by the activation of the permanent electro‐catheter in the posteroventral GPi. Conclusions. These findings confirm that, in selected patients, it is conceivable to target structures other than the conventional STN in order to maximize clinical benefit.

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.     

皮质发育障碍模型的建立及其致痫敏感性的研究

目的:建立皮质发育障碍模型,探讨皮质发育障碍模型的敏感性。方法:在SD大鼠孕17d腹腔注入1,3-二氯乙烯-亚硝基脲(BCNU)制作皮质发育障碍模型;Nissl染色观察P60d仔鼠病理变化;选取P60d雄性仔鼠,腹腔注射氯化锂-毛果芸香碱,分别比较两组大鼠癫发生的潜伏期、持续状态时间和死亡率。结果:同龄仔鼠脑组织湿重实验组比对照组显著减轻(P<0.01);Nissl染色显示皮质变薄、皮质层次紊乱、海马区域异位细胞异常聚集;有皮质发育障碍的仔鼠注射氯化锂-毛果芸香碱后,癫发生的潜伏期显著缩短(P<0.01),癫持续状态时间延长(P<0.01),死亡率显著升高(P<0.05)。结论:BCNU致皮质发育障碍模型具有癫易感性。     

阿尔茨海默病患者的执行功能障碍

目的了解阿尔茨海默病(A lzhe im er d isease,AD)患者执行功能损害状况及对于生活能力的影响,探讨执行功能障碍与记忆等AD常见认知功能损害的相关性。方法运用神经心理学测验的方法对40例AD患者及30例轻度认知功能损害(m ild cogn itive impairm ent,MC I)患者进行执行功能、记忆及其他认知功能检查,同时进行生活能力评定。另外选择40名健康老人作对照。结果AD组的执行功能测验成绩均显著低于健康对照组(P<0.01),其中额叶功能评定量表(FAB)(5.29±2.47)分,执行性画钟作业(CLOX1)(4.63±3.56)分,Stroop测验错误次数(Stroop1)(14.17±8.99)分,词语流畅性测验(RVR)(17.56±10.51)分。除Stroop测验反应时间(Stroop2)外,MC I组的其他执行功能测验成绩显著低于健康对照组(P<0.05),其中FAB为(7.67±2.44)分,CLOX1为(7.86±3.78)分,Stroop1为(7.21±8.07)分,RVR为(30.86±8.38)分。用多元逐步回归方法分析不同认知功能对生活能力的影响,结果为反映执行功能的FAB测验成绩处于第一位,独立与操作性日常生活能力(IADL)相关(β=-0.778,t=-7.079,P<0.01)。各项执行功能测验与年龄相关性不明显(r=0.026~0.250,P>0.05),与简易精神状态量表(MMSE)、记忆测验成绩相关性好(r=0.438~0.786,P<0.01)。结论AD患者具有明显的执行功能障碍;在尚未到达痴呆水平的MC I阶段也可发现执行功能损害。执行功能和整体认知功能及记忆等认知域功能具有良好的相关性。AD患者的执行功能障碍是导致生活能力下降的重要因素。

The Evidence Base Supporting the Subtyping of Gamblers in Treatment

Introduction Recent reviews found problem gamblers are heterogeneous and recommended subtyping gamblers in treatment studies. Objective Review factors (stage of change, preferred gambling activity, co-occurring disorder, and temporal instability of symptoms) for subtyping by evaluating the evidence for their effects on gambling treatment. Methods Literature review, evidence grading. Results Evidence is limited that any of the reviewed factors affects gambling treatment. Substantial evidence from prospective studies and other evidence from cross-sectional studies and the strong placebo response among pathological gamblers support the temporal instability of gambling symptoms. Conclusions Multiple studies are needed to develop the evidence base needed to subtype gamblers in treatment. Changes in the diagnostic criteria of pathological gambling may be necessary, especially to specify the persistence of gambling-related symptoms.
