多层螺旋CT对继发性附件扭转的综合评估

目的探讨继发性附件扭转的CT特征及其诊断效能,构建继发性附件扭转的评分系统。资料与方法收集经手术证实的伴有附件肿物的继发性附件扭转患者37例,以及伴有腹痛、附件肿物的对照组患者34例,分析继发性附件扭转的CT特征,采用受试者工作特征(ROC)曲线评价其诊断效能,构建继发性附件扭转的综合评分系统(AT-CI)。结果与对照组比较,继发性附件扭转以下CT特征发生率较高,包括肿物壁偏心性增厚(X^2=4.41,P<0.05)、附件出血(X^2=12.68,P<0.001)、肿物-子宫之间团块状结构(X^2=13.62,P<0.001)、旋涡征(X^2=10.71,P<0.05)、附件周围脂肪模糊/腹水(X^2=5.82,P<0.05)。其中肿物-子宫之间团块状结构敏感度及诊断价值最高,为81.1%(ROC曲线下面积0.71),旋涡征特异度最高,为91.2%。ATCI诊断效能优于任意单一CT特征(ROC曲线下面积0.83),评分0~2分继发性附件扭转可能性小,3~4分怀疑继发性附件扭转,评分>4分,则高度怀疑继发性附件扭转且特异度为100%。结论继发性附件扭转具有典型的CT特征,包括肿物壁偏心性增厚、附件出血、肿物-子宫之间团块状结构、旋涡征、肿物周围脂肪模糊/腹水。AT-CI是综合了继发性附件扭转全部CT特征的实用评分系统,提高了继发性附件扭转的诊断准确性。     

Can radiomics improve the prediction of metastatic relapse of myxoid/round cell liposarcomas?

European Radiology - The strongest adverse prognostic factor in myxoid/round cell liposarcomas (MRC-LPS) is the presence of a round cell component above 5% within the tumor bulk. Its identification...     

Treatment of classical Hodgkin’s lymphoma in children and adolescents

Introduction: The treatment of classical Hodgkin lymphoma (cHL) in children is a story of success. Nowadays, more than 90% of patients are cured and overall survival is nearly 100% at 5 years. Efforts have been made to avoid related effects of therapies; therefore, children are treated using different chemotherapy schemes in comparison with adults.

Areas covered: This review includes a view of the clinical classification and risk assessment in children suffering from HL. The chemotherapy more commonly employed is revisited. The use of PET/CT to evaluate the disease in order to guide therapy is analyzed. New options of chemotherapy and emerging immunotherapy are also included.

Expert opinion: In order to make the right treatment choice, a proper initial assessment of risk is mandatory. The choice of therapy in these kinds of patients must be done according to the experience of the team, and also, the cost and logistics related to the eligible scheme are very important. If possible, efforts must be made to include PET/CT in guiding therapy and avoiding overtreatment and long-term adverse effects in children. New options in immunotherapy are emerging and must be considered with caution in selected patients.     

吉西他滨化疗联合CIK细胞治疗胰腺癌的临床分析

目的分析吉西他滨化疗联合CIK细胞治疗胰腺癌的临床效果。方法将胰腺癌患者44例随机分为观察组(吉西他滨化疗联合CIK细胞治疗)与对照组(吉西他滨化疗)。结果比较两组总有效率,差异有统计学意义(P0.05);且治疗后,观察组患者KPS评分高于对照组,差异有统计学意义(P0.05)。结论吉西他滨化疗联合CIK细胞治疗胰腺癌的临床效果显著。

Objective

To systematically review literature on uptake and timeliness of diphtheria-tetanus-pertussis, measles-mumps-rubella, and/or polio-containing vaccines in infants who were born preterm, with a low birth weight, and/or with chronic health conditions that were diagnosed within the first 6?months of life.
