Surgical strategy of one stage surgery of anterior release combined with posterior correction in treatment of severe scoliosis

Objective: Severe scoliosis refers to scoliosis with serious and stiff curve. It always combins with trunk imbalance in coronal and sagittal contour. Besides complex pathological changes, cardiopulmonary deficits and other concomitant diseases increase treatmental difficulties. So the treatment of severe scoliosis is always a great challenge to spine surgeon. Methods :Thirty-six patients with severe scoliosis received one stage posterior correction followed by anterior release during July 1997 to January 2003, including 9 males and 27 females. Mean age was 17.2 years. Of them, 33 was idiopathic scoliosis and 3 was neurofibromatosis scoliosis( Cobb angle: 85-116 degree); 20 cases were abnormal in sagital plane. Three-dimensional devised instrumentation were applied such as CD, CD-Horizon, TSRH or Isola in posterior procedure followed by anterior release during the same anesthesia. 31 cases of this group received thorac icplasty. Results: The correction in the frontal plane achieved an average of 48.5%. In the sagittal plane, the pathological shape of the spine was reduced and distinctly ameliorated. 80. 6% of the patients maintained or achieved balance of sagittal plane. There were no complications of severe neurological deficit, hook displacement, rod broken, and deep infection at follow-up. One case occurred traumatic pleurisy after operation and another appeared pseudarthrosis 2 years later. One case demonstrated imbalance 11 months after operation. One patient was presented loss of correction more than 10 degree at one year follow-up and 5.2 degree in average. Conclusion:The study indicates that the one stage posterior correction combined with anterior release in treatment of severe scoliosis can achieve satisfactory correction. Appropriate choice of cases, preoperational detailed assessment and application of SEP and wake-up test during operation can possibly reduce severe complication. The long-term outcomes still need further observation.

云南省20年不同民族儿童体格发育与营养不良

目的 :动态分析近 2 0余年云南省不同时期不同民族儿童体格发育与营养状况变化规律 ,为今后儿童保健制定策略和措施提供参考依据 .方法 :用统一方法、统一标准分析、比较 1975年至 2 0 0 0年不同时期不同民族儿童体格发育与营养调查结果 .结果 :2 0余年来云南省儿童体格发育呈增长趋势 ,城市增长大于城郊增长 ,身高增长大于体重增长 .农村 5岁以下儿童中重度发育迟缓和中重度低体重患病率均呈下降趋势 ,中重度消瘦患病率呈上升趋势 ;不同民族下降幅度不同 ,至 2 0 0 0年 ,儿童营养不良患病率三项指标均未达到国家NPA目标 .结论 :2 0余年来云南省儿童体格发育呈增长趋势 ,农村 5岁以下儿童营养不良呈下降趋势 ,但下降幅度未达到国家NPA目标 ,5岁以下儿童营养不良仍是云南省农村儿童的主要健康问题 .     

EVALUATION OF IMMUNOHISTOCHEMICAL DIAGNOSIS OF RHABDOMYOSARCOMA

Objective To evaluate the sensitivity and specificity of regularly used immunohistochemical markers, including Vimentin (Vim), Desmin (Des), Myoglobin (MG), Myosin (MS), Smooth-muscle actin (SMA) and Sarcomeric actin ( Sr-A ) , in the diagnosis of rhabdomyosarcoma (RMS). Methods After resection, 24 RMSs and other childhood tumor specimens were fixed in 10% neutral-buffered formalin and embeded in paraffin. The immunohistochemical staining was performed by LSAB procedure. Heat-induced epitope retrieval of Des, MS, Sr-A was processed in order to enhence positive rate and positive strength. Results Vim, MG, MS, Des, Sr-A, SMA were arranged in the order of sensitivity from higher to lower. About specificity, Sr-A, Des, SMA, MG, Vim standed in a sequence from higher to lower ( the data of MS is insufficient) ; Des, MG, Sr-A possessedhigher experimental efficiency, followed by SMA, Vim in a succession. Conclusion Vim and MG are of the higher sensitivity but lower specificity. On the reverse, Sr-A and Des hoM the better specificity but lower sensitivity. So the combination of multiple antibody reactions shouM be considered to improve the diagnostic ability in poorly differentiated RMS. According to the result of experimental efficiency, we suggest that the combination of Des, MG and Sr-A can make it possible to diagnose the majority of RMS clearly.     

肺硬化性血管瘤的影像学与病理学对照研究

目的回顾性分析肺硬化性血管瘤(PSH)的影像学表现，并与病理学对照，旨在提高对PSH影像表现的认识。方法1976年1月至2002年12月由手术及病理证实的PSH共45例，其中男3例，女42例(93．3％)，年龄18～67岁，中位年龄49岁。无症状由体检发现19例(42．2％)。影像学资料(包括胸部正、侧位X线片和CX)完整的PSH共20例。平扫7例，直接增强扫描13例。将影像表现与病理对照。结果典型X线片表现为圆形、卵圆形边界清楚的肿物或结节，无分叶及毛刺。CT平扫7例，病变密度与肌肉密度相仿。直接增强扫描13例，9例为均匀强化(其中4例增强早期呈不均匀强化，延时后均匀强化)，4例呈不均匀强化，强化程度略高于或明显高于肌肉密度，强化的最大CT值为135HU。13例增强CT的病变中，强化程度高于或明显高于肌肉的11例，全部含有较多的血管瘤成分。含有较大面积低密度区的1例，组织学显示有囊变。影像检查见有钙化的5例均与病理学所见吻合。结论有助于PSH影像诊断的指标为：(1)40-60岁的女性患者；(2)胸片上表现为圆形、卵圆形边界清楚的肿物或结节；(3)CT平扫密度均匀，有时有小低密度区和粗大点状钙化，偶尔可见囊性变；(4)CT增强后有中度至明显强化。对于增强早期呈明显不均匀强化的圆形、卵圆形边界清楚的肿物或结节，应行延时扫描。
