Atypical Abnormal Pulmonary Vein Drainage with Atrial Septal Defect: Surgical Treatment

Sinus venosus atrial septal defect (SV‐ASD) usually coexists with partial anomalous pulmonary vein connection (PAPVC). It is a difficult diagnosis in transthoracic echocardiography (TTE) due to eccentric position of defects. We present a rare case of atypical anatomical variation in PAPVC, which was never described before. Two right pulmonary veins drained into superior vena cava, which overrode SV‐ASD and interatrial septum, a third pulmonary vein into the right atrium. Complete diagnosis could not be set after TTE, nor transesophageal echocardiography, whereas angio‐CT was finally conclusive. This diagnostic approach allowed the surgical planning.     

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.     

补肾纳气法治疗小儿支气管哮喘的临床分析

目的：探讨分析补肾纳气法治疗小儿支气管哮喘的临床效果。方法方便选取该院儿科于2013年3月—2014年11月收治的小儿支气管哮喘患者67例，根据随机数字法分为对照组33例和观察组34例，对照组患者予以氨茶碱片治疗，观察组患者实施补肾纳气法治疗，观察两组患者的治疗效果，进行临床对照性分析。结果对照组患者不良反应发生率24.2%，观察组患者不良反应发生率5.8%，观察组不良反应发生率明显低于对照组(P﹤0.05)；对照组患者总有效率60.6%，观察组患者总有效率85.3%。观察组患者治疗后总有效率明显高于对照组(P﹤0.05)。结论补肾纳气法治疗小儿支气管哮喘的临床效果好，应用价值高，值得在临床实践中推广应用。     

支气管哮喘患儿中性粒细胞胞外诱捕网水平与患者免疫功能及临床预后的关系

目的探讨支气管哮喘患儿中性粒细胞胞外诱捕网水平与患者免疫功能及临床预后的关系。方法选取本院2017年9月-2018年9月支气管哮喘患者80例作为观察组,并以同期健康体检的30例儿童作为对照组,采用pico Green dsDNA荧光染色定量检测支气管哮喘患者NETs水平,采用T淋巴细胞亚群评价患者免疫功能,对比不同NETs水平患者免疫功能及临床特点,采用Logistic回归分析探讨小儿支气管哮喘急性发作的风险因素。结果观察组白细胞、中性粒细胞、单核细胞、Cf-DNA/NETs水平均高于对照组(P <0. 05),而淋巴细胞水平低于对照组,差异均有统计学意义(P <0. 05)。Logistic回归分析显示,哮喘家族史、呼吸道感染、Cf-DNA/NETs水平上升、有害气体接触、被动吸烟均是支气管哮喘急性发作的独立危险因素(P <0. 05)。结论中性粒细胞胞外诱捕网水平与支气管哮喘患者免疫功能及预后密切相关,值得临床重点关注。     

经肺动脉与支气管动脉血管造影的CTA观察原发肺癌的血供

目的用支气管动脉(BA)和肺动脉(PA)造影CTA观察肺癌血供情况。方法前瞻性观察6例支气管肺癌患者,分别行体循环动脉和肺动脉数字减影血管造影(DSA)后,留置BA导管与PA导管行CTBA与CTPA,观察BA与PA对肺癌的血供。结果CTPA上,无体动脉与左心强化的图像上肿瘤未见强化,有体动脉或左心强化的图像上见肿瘤边缘强化,CT强化值为10.0~45.6 Hu。CTBA上肿瘤部分明显强化,CT强化值为150.3~320.7 Hu,可见杂乱无章的肿瘤血管影,3例见纵隔淋巴结强化。结论本组病例观察表明原发性肺癌由BA为主的多发体循环动脉供血,未发现PA参与供血。     

老年人支气管异物延误诊治原因

目的探讨老年人支气管异物延误诊治的原因。方法对28例误诊的老年人支气管异物临床表现及误诊情况进行分析。结果老年人支气管异物病史诉说不清,临床缺乏特异性,医生重视不够,容易误诊为呼吸系统疾病。结论老年患者疑为支气管异物者,应详细询问病史,抗感染治疗无效时,应及时行纤维支气管镜检查。     

44例老年重症哮喘的院前急救体会

目的探讨老年重症哮喘急性发作的院前急救措施。方法在常规平喘治疗基础上,治疗组用甲基泼尼松龙80mg加入5%葡萄糖溶液(0.9%氯化钠溶液)40ml中静脉注射,对照组用地塞米松10mg加入5%葡萄糖溶液(0.9%氯化钠溶液)20ml中静脉注射,观察治疗前、后两组患者临床疗效评分变化。结果治疗组比对照组起效快,疗效好,两组疗效间差异有显著性意义(P<0.01)。结论甲基泼尼松龙是老年重症哮喘院前急救的首选方法,尽早使用,有利于提高抢救成功率。     

Respiratory function and bronchial reactivity in mill workers

Professional exposure to vegetable dusts affect the respiratory function of the exposed subjects. A previous survey conducted in an industrial flour-mill demonstrated a higher frequency of respiratory symptoms in workers compared to a control group. Ten subjects employed in a work site particularly exposed to dust were studied. Each subject answered a questionnaire and performed on Mondays and Fridays, at the begenning and end of his work shift, a flow volume curve and an isocapnic hyperventilation test. The aerobiology of the professional environment was also measured. We noted: 1) in the flow volume curves: a drop in the FEV₁ during the Monday morning shift, a significant difference between the FEV₁ (p<0.05) and the MMEFR 25–75 (p<0.05) measured at 6 am on Monday and Friday, and between the MMEFR 25–75 values obtained at 12 noon on Monday and Friday (p<0.05). 2) after isocapnic hyperventilation, a significant drop in the MMEFR 25–75 at 6 am on Monday (p<0.01) and in the FEV₁ and MMEFR 25–75 at 12 noon on Mondays (p<0.05), a significant drop in the FEV₁ at 1 pm on Monday (p<0.01).
