Pediatric cardiac computed tomography angiography: Expert consensus from the Filiale de Cardiologie Pédiatrique et Congénitale (FCPC) and the Société Française d’Imagerie Cardiaque et Vasculaire diagnostique et interventionnelle (SFICV)

This article was designed to provide a pediatric cardiac computed tomography angiography (CCTA) expert panel consensus based on opinions of experts of the Société Française d’Imagerie Cardiaque et Vasculaire diagnostique et interventionnelle (SFICV) and of the Filiale de Cardiologie Pédiatrique Congénitale (FCPC). This expert panel consensus includes recommendations for indications, patient preparation, CTA radiation dose reduction techniques, and post-processing techniques. The consensus was based on data from available literature (original papers, reviews and guidelines) and on opinions of a group of specialists with extensive experience in the use of CT imaging in congenital heart disease. In order to reach high potential and avoid pitfalls, CCTA in children with congenital heart disease requires training and experience. Moreover, pediatric cardiac CCTA protocols should be standardized to acquire optimal images in this population with the lowest radiation dose possible to prevent unnecessary radiation exposure. We also provided a suggested structured report and a list of acquisition protocols and technical parameters in relation to specific vendors.

目的 了解2009-2019年西安市肺结核的流行特征及治疗转归情况，为完善西安市肺结核防治策略提供依据。方法 收集2009-2019年《传染病信息管理系统》中登记的肺结核患者病案信息数据，通过描述性研究方法对肺结核流行病学特征和治疗转归情况进行分析。结果 2009-2019年间西安市肺结核年平均发病率为49.06/10万。郊县、郊区、城区肺结核年平均发病率分别为54.13/10万、47.46/10万和46.19/10万；男性发病率是女性的1.85倍。职业分布排在前5位的为农民（47.48%），家政、家务及待业（14.65%），离退人员（9.55%），学生（8.63%）和工人（5.23%）。利福平敏感或耐药性未知患者的成功治疗率平均为98.03%，利福平耐药患者治疗成功率为51.47%。结论 西安市近年来肺结核发病率和治疗率呈增长趋势，利福平耐药患者治疗成功率较低，要加强对重点人群的健康促进工作，加大肺结核发现力度及患者治疗管理工作。     

四妙勇安汤方源探析

四妙勇安汤由金银花、玄参、当归、甘草4味药物组成,为《古代经典名方目录(第一批)》中100个经典名方之一。经溯源发现,四妙勇安汤源于《石室秘录》,后由《古今图书集成·医部全录》《验方新编》等书引用。从古代文献记载来看均有方无名,"四妙勇安汤"之名,最早见于1956年《中医治疗动脉栓塞性坏疽症的成效》,是由当时记者吕民报道河北省释迦宝山用"四妙勇安汤"治疗当地的动脉栓塞性坏疽时冠名。四妙勇安汤从方药组成与剂量上看,从《石室秘录》开始即是"金银花三两,当归二两,生甘草一两,玄参三两",历代版本《方剂学》确定四妙勇安汤金银花、玄参、当归、甘草的比例就是3∶3∶2∶1。而查阅文献,释迦宝山临证所用的四妙勇安汤由"玄参132 g,当归99 g,银花66 g,甘草33 g"组成,金银花、玄参、当归、甘草的比例变成2∶4∶3∶1。从治疗时间上看,原方记载的7日愈或是10日愈,而释迦宝山将其用到了三四个月,甚至五六个月。研究认为,古籍中的四妙勇安汤,应该是用于疾病的初期,尽早发现和治疗;而释迦宝山修改过的剂量,是广泛用于脱骨疽的中后期,甚至出现坏疽的严重病情所使用的,因此服药时间长,剂量大。且四妙勇安汤临证不仅限于治疗脱骨疽,也用于大头疮等,现代该方的使用已经大为拓展。相关研究已证实四妙勇安汤具有抗炎、稳定斑块、降脂、保护血管、改善血液流变学、抗凝、抑制血栓形成和促纤溶等作用,后续应开展君臣佐使辨析,对其临床应用范围重新进行界定。     

成人Still病诊疗进展

【摘要】 成人Still病是一类病因未明的全身炎症性疾病，临床表现多样，其诊断和治疗存在一定困难。近年来发现，血红素加氧酶1、钙网蛋白、炎症细胞因子、糖基化终末产物等新型标志物可对成人Still病的活动程度和严重程度进行全面评估，而新研发的生物制剂如肿瘤坏死因子抑制剂、白细胞介素1（IL-1）抑制剂、IL-6抑制剂、重组IL-18结合蛋白也有望用于治疗。本文主要综述成人Still病的诊断和治疗进展。     

Open, Double-Blind and Long-Term Study of Vigabatrin in Chronic Epilepsy

We performed an open, double-blind, and long-term study of vigabatrin (gamma-vinyl-GABA, GVG) in patients with treatment-resistant epilepsy who were receiving only one or at most two standard antiepileptic drugs (AEDs). The novel design included a parallel, double-blind, placebo-controlled phase that minimized the number of patients receiving placebo and allowed determination of the optimum dose of GVG for each patient before initiation of the double-blind phase. The study was divided into four phases. The first phase was a 6-week period of baseline observation. In the second phase, GVG was added openly to previous AEDs for 8 weeks. During the first 2 weeks of this phase, the dose of GVG was increased weekly and then, in the absence of adverse effects, was held constant for the next 6 weeks. At the end of this open phase, seizure frequency during the 6 weeks of constant treatment was compared with the baseline seizure frequency for each patient. Patients who experienced reduction greater than 50% in the frequency of any seizure type during the open phase were defined as responders. These responders were then entered into the third and double-blind phase, in which they were randomly allocated wither to continue active GVG treatment or placebo for 8 weeks. Thirty-three patients entered the study; 31 of 33 patients completed the initial open phase. Twenty patients achieved a reduction greater than or equal to 50% in the frequency of one or more seizure types and were eligible for the double-blind phase; 10 were randomized to continue GVG and 10 were randomized to placebo.(ABSTRACT TRUNCATED AT 250 WORDS)

IHPBA in Tokyo, 2002: surgical treatment of IPMT vs MCT: a Japanese experience

The differences and similarities between intraductal papillary mucinous tumor (IPMT) and mucinous cystadenoma or carcinoma (mucinous cystic tumor; MCT) of the pancreas have been noted. The similarities include: (1) both tumors originate from pancreatic duct cells, (2) massive mucin production is found in both tumors, and (3) papillary projection is a common histological characteristic. However, there are also many differences. IPMT is most frequently found in men in their sixties, and originates in the head of the pancreas, with 62% (123/199) of tumors reported to be found in the head of the pancreas. This tumor sometimes spreads throughout the entire pancreas. The tumor itself basically is of the dilated pancreatic duct type, and the prognosis is generally good. In contrast, MCT frequently develops in women in their forties. This tumor is usually large, round, and almost totally encapsulated by fibrous tissue, with no communication with the pancreatic duct. The tumor histologically has an ovarian-like stroma. It most often develops in the body or tail of the pancreas. Invasion is often present and the operative prognosis is not good. IPMT resembles the shape of a bunch of grapes and MCT resembles that of an orange. From the differences between these two types of tumors, they are classified into different categories. With regard to therapeutic strategies for MCT, the tumor should be resected with lymph node dissection immediately when it is detected. In contrast, some patients with branch-type IPMT can be followed without surgical procedures. Because IPMT shows good prognosis and little tendency for infiltration, some kinds of organ-preserving procedures would be possible for some patients with this tumor. Such organ-preserving procedures are: duodenum-preserving pancreas head resection, spleen-preserving distal pancreatectomy with conservation of the splenic artery and vein, and so on.
