Neuropsychological sequelae of brain tumors

Investigation of the neuropsychological sequelae of brain tumors is extremely complex largely because the neurobehavioral consequences of brain tumors depend upon complex interactions among disease and treatment variables as well as patient characteristics. To illustrate some of these complexities, we present case studies of two patients in whom the behavioral outcome was not easily predictable on the basis of our current understanding of brain-behavior relationships in tumor patients. The case studies do illustrate how neuropsychological evaluation aids in identifying cognitive deficits which have implications for subsequent quality of life. Recommendations for future experiments and statistical analyses of neurobehavioral data of this population are given.     

MR imaging of bone and soft tissue tumors

One hundred sixty-one patients with tumors of bone or soft tissues underwent MRI. We believe to be able to differentiate benign from malignant lesions on the basis of imagings at internal, marginal, and peripheral properties. MR imagings demonstrated specific morphologic features that suggest the correct tissue diagnosis. MR imagings with STIR method or Gd-DTPA were more valuable. Because of the high contrast between the tumors and normal tissue, especially by STIR method, MRI provides improved detection and delineation of bone soft tissue tumors when compared to other diagnostic modalities.     

胸腰椎转移性肿瘤术后感染的临床分析

目的探讨胸腰椎转移性肿瘤术后感染的临床因素,以期提高临床治疗水平。方法回顾性分析2011年1月-2013年4月155例胸腰椎转移性肿瘤手术患者,对其中发生术后感染23例患者进行病原菌分布和危险因素分析,采用SPSS 16.0进行统计分析。结果 155例胸腰椎转移性肿瘤手术患者术后发生感染23例,感染率为14.84%,其中感染部位以呼吸道和切口为主;病原菌以革兰阴性菌为主共19株占61.30%,其中大肠埃希菌9株占29.04%;年龄、术中出血量、脊柱外骨转移、主要内脏器官转移、术前Frankel分级、术前Tokuhashi评分是胸腰椎转移性肿瘤术后感染危险因素(P<0.05)。结论胸腰椎转移性肿瘤术后感染原因众多,临床应注意规范操作且对症治疗。
