精神分裂症首次发病患者的磁共振弥散张量显像研究

目的探讨从未用过药的精神分裂症首次发病(以下简称首发)患者的重要白质及部分灰质区的磁共振弥散张量显像(DTI)的特点。方法选取9例首发精神分裂症患者(患者组)及9名年龄、性别、受教育程度与患者组相配对的健康者,应用DTI成像技术检测脑额颞交界处、内囊等白质区和颞中回灰质、中央前回、中央后回等灰质区的各向异性(FA)、表观扩散系数(ADC)及双侧海马体积。结果患者组及对照组组内左右两侧兴趣区FA值及ADC值的差异无统计学意义(P>0.05);患者组与对照组各感兴趣区FA值差异无统计学意义(P>0.05),但患者组颞中回灰质(8.655×10-9)、中央前回(7.816×10-9)、中央后回(7.855×10-9)ADC值高于对照组(分别为7.428×10-9,6.921×10-9,7.013×10-9;P=0.049,0.009,0.005);两组内及组间双侧海马体积比较,差异均无统计学意义(P>0.05)。结论首发精神分裂症患者与健康者DTI参数之间没有明显区别。     

术中电生理动态监护下显微手术切除椎管神经鞘瘤（附65例报告）

目的 探讨术中电生理监护对椎管神经鞘瘤显微手术中的作用及意义，提高对椎管内神经鞘瘤的治疗水平。方法 回顾性分析65例术中电生理动态监护下，显微手术切除椎管内神经鞘瘤。结果 治愈60例（占92．3％），好转5例（占7．7％），无死亡；肿瘤全切62例，次全切除3例，全切率95．4％。结论 常规动态电生理监测下显微手术切除椎管神经鞘瘤，能保全脊髓神经的功能，减少副损伤，提高手术安全性；显微手术有助于提高肿瘤全切率，可有效减少术后复发。对影响脊柱稳定性的行脊柱融合内固定。     

Wirkung und Wirkfaktoren von psychodramatischem Coaching — Eine experimentelle Evaluationsstudie

Zusammenfassung Diese Studie untersucht, wie Erfolg im Einzelcoaching entsteht und was Psychodrama dazu beitragen kann. Dabei werden zun?chst die vier Berner Wirkfaktoren dargestellt, die im Rahmen einer allgemeinen psychologischen Coachingkonzeption die vier m?glichen Erfolgsstrategien darstellen. über Videoauswertung und schriftliche Befragung aller Beteiligten wurden 35 Einzelsitzungen evaluiert. Dabei zeigten sich die vier Wirkfaktoren tats?chlich als elementar in kurz- und mittelfristig erfolgreichen Coachingprozessen. In dem experimentellen Vergleich wurde das psychodramatische Coaching zudem wesentlich besser bewertet als das Vergleichscoaching, was durch den Ressourcen- und Wachstumsfokus sowie die sehr gute Beziehungskompetenz der Psychodramatiker erkl?rt werden kann. Des Weiteren zeigen die Auswertungen, dass ein dosierter und gezielter Einsatz des psychodramatischen Methodenrepertoires fruchtbarer zu sein scheint als der zeitlich umfassende Einsatz des Psychodramas als Hauptinterventionsmethode.

Summary The present study investigates the process of success development in one-to-one-coaching and examines how the method of psychodrama can contribute to this process. First the four change factors are presented. They represent the four success strategies in a general psychological coaching approach that can be chosen by the coach. Second 35 one-to-one-coaching sessions are evaluated by a video-based rating-system and questionnaires that were filled in by all coaches, clients and employees of the clients. In these analyses the four change factors were shown to be critical for short- and medium-term success. In an experimentally designed assessment the psychodramatic coachings had a considerably better result than the comparative coaching. This outcome could be explained by the focus on resources and growth and the high competence of the psychodramatic coaches to set up an appreciative coaching relationship. The analyses demonstrate furthermore that the well-aimed and specific use of psychodrama methods is more fruitful than its time-extensive use as the main intervention method.

HLA markers in familial Lichen Sclerosus

Background: Lichen sclerosus (LS) has been identified with increased frequency in families,often associated with HLA markers, mainly DQ7. A genetic co‐etiology seems likely in this setting. Moreover, there is an association of LS with autoimmune disorders, such as the presence of anti‐thyroid peroxidase autoantibodies (anti‐TPO), a hallmark of autoimmune thyroid diseases. Patients and Methods: In 3 families affected by LS, we verified their HLA markers, and identified previously undiagnosed cases of LS and autoimmune disorders. 30 individuals were examined with history, skin biopsy, HLA class I and II typing by PCR‐SSP, and measurement of anti‐TPO, free thyroxine and thyroidstimulating hormones (TSH) levels. Results: There were 8 cases of LS, 50 % of them anti‐TPO+. Autoimmune disorders were found in 40 % (total) and in 87.5 % of those affected. Most common HLA markers were B*15, B*57, CW*03, CW*07, CW*18, DRB1*04, DRB1*07, DRB4*. The three latter have been previously associated with LS. Conclusion: New cases of LS and autoimmune disorders can be detected in first degree relatives of patients with LS. The presence of anti‐TPO antibodies strongly suggests autoimmune thyroiditis. There is intra‐familial association between the haplotype HLA‐B*15 ‐DRB1*04 ‐DRB4* and anti‐TPO,emphasizing their link with thyroiditis. New familial approaches might help to make clear the pathogenesis of LS and its association with autoimmune diseases.     

Methodological issues in conducting research with refugee women: Principles for recognizing and re‐centering the multiply marginalized

Many recent efforts in the field of community psychology have been dedicated to moving from values to action in incorporating diversity into our work. An essential aspect of this goal is designing research that provides opportunities for underrepresented perspectives to be heard. The voices of refugee women, in particular, are not typically incorporated in research, planning for service provision, and policy design. This article explores methodological challenges involved in conducting research with refugee women who are marginalized both within broader U.S. contexts and within their own communities. Six guiding principles are presented: 1) develop strategies for involving marginalized refugee women; 2) consider the advantages and limitations of quantitative and qualitative methodologies and be innovative about combining them; 3) prepare for extensive time and effort for quantitative measure construction; 4) consider gendered decision‐making structures in the lives of refugee women and their potential impact on the research process; 5) plan for refugee women's common triple burden of working outside of the home, managing their households, and adjusting to life in a new country; and 6) attend to refugee women's cultural norms about and unfamiliarity with the interview process. © 2004 Wiley Periodicals, Inc.
