回收式自体输血在儿童先天性髋关节脱位手术中的应用

[目的]探讨儿童先天性髋关节脱位的股骨和骨盆联合手术中洗涤式自体血液回收的应用方法与前景。[方法]2003年8月~2005年12月,17例先天性髋关节脱位股骨和骨盆联合手术中,使用Cell Saver 5血液回收系统行术中的血液回收。观察回输自体血液后的并发症发生情况,记录术中估计失血量、实际回收血量,以及回输血前后的Hb、Hct、P lt、PT、APTT、HR、BP、SPO2等的变化情况。[结果]17例患儿术中血液回收总量2 090 m l,平均每人(171±53)m l。其中4例出现一过性血红蛋白尿,其他无并发症。患者术前和术后24 h的Hb、Hct、HR比较差异有显著性意义(P<0.01);患者术前和术后24 h的P lt、PT、APTT、SPO2、BP比较差异无显著性意义(P>0.05)。[结论]儿童先天性髋关节脱位的股骨和骨盆联合手术中的血液回收是安全、有效的自体输血方式,明显节约异体血的用量,有效避免血液传播性疾病的发生。     

王成荣诊治月经过少经验谈

分析年龄、有无宫腔操作史等病因;注重问诊、妇科及其辅助检查等诊断方法;根据年龄及有无人流史等进行辨证施治,从冲任不足和冲任虚瘀2个方面诊治月经过少,收效较好。     

腹腔镜治疗精索静脉曲张235例

目的探讨腹腔镜治疗精索静脉曲张的疗效. 方法回顾分析1993年9月～2003年7月235例经腹腔镜精索静脉高位结扎术的临床资料. 结果 235例手术均获成功,手术时间5～20 min,平均12 min.术后住院2～5 d,平均3 d.210例随访6～18个月,9例复发,复发率4.3%(9/210),不育11例术后6～12个月后其妻受孕. 结论腹腔镜精索静脉高位结扎术微创、美观、疗效好,对双侧精索静脉曲张、开放性手术后复发和有腹股沟区手术史者尤为适用.     

基层医院重症监护病房的医院感染特点及其对策

目的分析基层医院重症监护病房(ICU)的医院感染特点,提出相应的防范措施,以有效降低医院感染发生率. 方法以主动监测与系统回顾相结合的方法,对2003年全年入住ICU 383例患者的相关临床资料进行分析评判,并与全院住院患者进行对比. 结果 ICU的医院感染率是28.8%,显著高出同期的医院平均感染率23.6个百分点;因医院感染而导致死亡的占ICU总死亡的36%;ICU医院感染的病原菌以G-菌为主,占50%,而双重感染达78.7%;下呼吸道感染为医院感染的主要部位占61.7%,但多部位多器官感染占29.6%. 结论 ICU医院感染的特点是高发病率、高死亡率、高耐药性;其相关因素有病情重、年龄大、基础疾病多、侵入性诊疗操作多与交叉感染等.     

更昔洛韦治疗婴幼儿手足口病的疗效观察

目的 探讨更昔洛韦对婴幼儿手足口病（HFMD）的临床疗效。方法 将65例婴幼儿HFMD患儿随机分为治疗组和对照组，治疗组加用更昔洛韦，观察临床有效率及不良反应率，并对结果进行统计学分析。结果 临床有效率治疗组为90．91地，对照组56．25％，引起白细胞下降，血小板下降治疗组为33．33％、27．27％，对照组为9．38％、3．13％，差异均有显著性。结论 治疗组疗效优于对照组，但须随访对白细胞和血小板的影响。     

Influence of tumours on normal cells and optimal chemotherapy regimens: the case of several drugs and toxicity constraints.

Cancer chemotherapy with the application of several drugs is studied. The negative and inhibiting effect of the tumour on normal cells is taken into account. Under certain hypotheses, we determine the optimal regimen that minimizes the tumour burden at the end of a fixed period of therapy while maintaining several normal cell populations above prescribed levels. More precisely, it is demonstrated that the optimal drug administration corresponds to the strategy of intensive chemotherapy.     

Aspiration biopsy cytology of mammary myoepithelioma

A case of ultrastructurally confirmed myoepithelioma of the breast studied by fine-needle aspiration biopsy is reported. Aspirated tumor cells were spindle-shaped with well-defined cytoplasm and oval nuclei showing no remarkable nuclear pleomorphism. They were seen mainly in irregular bundles with strong cellular cohesiveness. Their cytoplasm contained S-100 protein demonstrated by the peroxidase antiperoxidase staining technique.     

Undergraduate psychiatry teaching in Ethiopia

Many epidemiological studies have shown the magnitude and seriousness of mental disorders in developing countries. However, mental health care remains unsatisfactory owing to lack of skilled manpower and many other social and medical priorities. General practitioners and other health personnel can significantly help in extending mental health care provided they receive adequate training during their medical curriculum. With this aim, the Department of Psychiatry at Addis Ababa University runs a 6-week full-time course for undergraduate medical students. Its chief objectives, teaching methods, achievements and shortcomings are discussed in the paper.
