原发女性生殖道恶性黑色素瘤21例临床分析

目的探讨原发性女性生殖道恶性黑色素瘤的临床特点、治疗及预后。方法回顾分析本院1986年1月至2006年3月收治的原发性女性生殖道恶性黑色素瘤患者21例。其中外阴8例、阴道10例、阴道及宫颈1例、外阴及阴道1例、盆腔1例。结果患者中位年龄50(21~71)岁。临床表现主要为阴道流血、流液及发现外阴或阴道肿物。本资料阴道恶性黑色素瘤发病率高于外阴恶性黑色素瘤。按照国际妇产科联盟(FIGO)分期,期别和预后呈负相关。治疗以手术为主,手术方式由根治性切除逐渐衍变为扩大局部切除。随访:21例患者中随访率为67%(14/21),随访时间6~96个月,死亡7例,随访期间的死亡率为50%。结论女性生殖道恶性黑色素瘤发病率低,预后差。肿瘤厚度和淋巴结转移是其主要的危险因素。应采用手术基础上的综合治疗,治疗方案个体化。     

Autonomy and modernisation: the management of change in an English primary care trust

Recent New Labour policy for the ‘modernisation’ of Government places a good deal of emphasis on decentralisation. This emphasis is particularly marked in relation to the organisation of primary care. However, like hospitals and other National Health Service institutions, primary care trusts (PCTs) are subject to a substantial raft of centrally established performance targets and indicators, including those which contribute to the public award of between zero and three performance ‘stars’. This raises questions about the extent to which employees can exercise autonomy in the context of rigid top‐down directives. This paper presents findings from a study using participant observation and interviews to examine the impact of a training course aimed ostensibly at increasing employee autonomy in an English PCT. The suggestion is that attempts to make employees more autonomous can be seen as a strategy for increasing central control based upon the internalisation by the employees of centrally promulgated values. The attraction of such strategies is that they may be potentially more effective and less costly than alternative strategies of direct control. However, the study suggests that the outcome of attempts by such methods as programmes to increase employee autonomy may be very different from those intended.     

Soul City: a sustainable edutainment vehicle facilitating social change

This paper outlines the programming model employed by the Soul City Institute for Health and Development Communication, a South African NGO, in using ‘edutainment’ to facilitate social change. The paper refers to the intersection of this model and current thought on health promotion and various social change theories. It also discusses key challenges and factors contributing to sustainability over 12 years.     

原发性乳腺恶性淋巴瘤的诊断及外科治疗探讨

目的探讨原发性乳腺恶性淋巴瘤的诊断与治疗. 方法回顾性分析我院1992～2004年5例原发性乳腺恶性淋巴瘤的临床资料.5例均为术后组织学病理诊断.4例行乳腺癌改良根治术,1例行乳房单纯切除术.5例均行化疗及放疗. 结果乳腺癌改良根治术手术时间60～120 min,平均80 min;乳房单纯切除术加乳腔镜腋窝淋巴结清扫术手术时间75 min.术中出血量150～250 ml,平均200 ml.术后病理组织诊断均为弥漫性非霍奇金氏淋巴瘤,为B细胞来源.且均有腋窝淋巴结转移.全组病例随访6个月～12年,平均4.5年.2例II期,均死于肿瘤多器官转移;3例I期,肿瘤无复发. 结论原发性乳腺恶性淋巴瘤无明显特异性表现,术前诊断困难.钼靶X线照相,对诊断有帮助. 治疗可选择手术、放疗、化疗或单纯给予化疗和放疗.     

CT导向下125I种子源植入治疗恶性肿瘤
