Corynebacterium species as one of the major causative pathogens of bacterial pneumonia

Recent advances using molecular methods, matrix-assisted laser desorption ionization time of flightmass spectrometry, and next-generation sequencers enable rapid and precise detection of bacterial species in the clinical samples, revealing bacterial diversities in the human body. Corynebacterium species are Gram-positive bacilli, which can cause pneumonia and have been reported as causative pathogens of lower respiratory tract infections since the 1970's. However, Corynebacterium spp. may be recognized and sorted as part of normal respiratory flora on Gram staining and culture, resulting in clinical under-recognition as pathogenic bacteria.The results of the clone library method using bacterial 16S ribosomal RNA gene sequence analysis in Japanese patients with hospital-acquired pneumonia revealed that bronchoalveolar lavage fluid obtained from the lung lesions contained 11.8% Corynebacterium spp., which was the second most predominant bacterial phylotype. Additionally, among patients in whom Corynebacterium spp. were detected, C. simulans was most commonly detected followed by C. striatum. In addition, almost half of the patients in whom C. simulans was detected was monophylotypic infection and/or co-detection of C. simulansand C. striatum. Further clinical information is expected on corynebacteria as pathogens of lower respiratory tract infection.     

反复感染手足口病患儿的预防和治疗

目的探讨消毒隔离结合免疫及营养治疗在预防和治疗反复感染手足口病患儿中的作用。 方法收集初次就诊的手足口病患儿共400例，利用随机数字表将患者分为治疗组与对照组各200例，治疗组患儿定期给予消毒隔离健康教育及营养随访，再次患病后给予个体化营养支持治疗。对照组患儿仅在感染手足口病后给予常规治疗。比较两组患儿手足口病再发率和重症率等指标。 结果治疗组患儿平均退热时间为（1.7 ± 1.1）d、皮疹消退时间为（4.0 ± 1.3）d、平均住院天数为（5.6 ± 2.4）d、抗菌药物使用率为19%（38/200）、激素使用率为8%（16/200），均显著低于对照组，差异具有统计学意义（t = 10.028、8.677、8.353、20.650、11.312，P = 0.015、0.032、0.001、0.004、0.011）。治疗组患儿1年内再发率、重症率和并发症发生率分别为12%（24/200）、1%（2/200）和5%（10/200），显著低于对照组患儿，差异均有统计学意义（χ² = 9.21、0.88、7.24，P = 0.010、0.002、0.007）。 结论健康教育、营养随访及个体化营养支持治疗可降低手足口病的再发率及重症率，改善临床结局。     

不同细胞类型咳嗽变异型哮喘的临床特征分析

目的比较不同细胞类型的咳嗽变异型哮喘患者的临床特征差别。方法选择2014年12月至2017年3月在本院咳嗽门诊就诊的慢性咳嗽患者,遵循中国慢性咳嗽指南(2015版)诊治流程,在询问病史、临床症状和获得体征的基础上,进行血常规、胸片、肺通气功能+气道反应性、诱导痰细胞学分类等相关检查,依据检查结果和治疗反应,确定病因诊断,筛选出咳嗽变异型哮喘,依据诱导痰细胞学分类计数检查结果进行分组,比较不同细胞类型的成人咳嗽变异型哮喘患者的临床特征差别。结果共收集诊断明确且病因单一的成人咳嗽变异型哮喘患者114例,占所有慢性咳嗽患者的32.95%,其中男性56例(48.7%),女性58例(51.3%)。按细胞类型分类:嗜酸性粒细胞增多型23例(20.2%),中性粒细胞增多型53例(46.5%),寡细胞型14例(12.3%),混合细胞型24例(21.1%);分组比较显示:中性粒细胞增多型年龄最长(P=0.042),而嗜酸性粒细胞增高型患者的FeNo值水平最高(P<0.001);混合细胞型患者咳嗽时间最长(P=0.012),与寡细胞型相比较,混合细胞型患者有明确体育锻炼史(P=0.007)。结论不同细胞类型的成人咳嗽变异型哮喘患者的临床特征存在较明显的差别,可以用于指导临床疾病管理。     

Efficiency of anisodamine for organophosphorus-poisoned patients when atropinization cannot be achieved with high doses of atropine

Poisoning by organophosphorus insecticides is a major global public health problem. Although atropine has been widely used to treat organophosphate (OP) poisoning, sometimes atropinization cannot be achieved, even with high doses of atropine. Hence, we aimed to assess the effect of anisodamine for organophosphorus poisoned patients for whom atropinization could not be achieved through high doses of atropine. In this study, sixty-four OP-poisoning patients, all of whom accepted routine treatments but who did not attain atropinization after high doses of atropine for 12 h, were enrolled. The result showed that the time to atropinization was 24.3 ± 4.3 h in the anisodamine group, significantly shorter than in the atropine group (29.2 ± 7.0 h, p < 0.05); the hospital stay in the anisodamine group was 5.3 ± 2.5 days, significantly shorter than the 6.9 ± 2.3 days needed by the atropine group (p < 0.05). We draw a conclusion that anisodamine can shorten the process of atropinization and hospital stay in organophosphorus poisoned patients for whom atropinization cannot be achieved with high doses of atropine.     

A case of community-acquired pneumonia due to influenza A virus and Nocardia farcinica co-infection

Nocardia spp. has not been reported previously as a cause of post-influenza pneumonia. Here we present a first case of post-influenza bacterial pneumonia due to Nocardia farcinica. Initial reason for hospitalization of the 90 year old female patient was a pneumonia with the symptoms of fever and productive cough. A rapid test for influenza antigen was positive for influenza A virus. Treatment with Zanamivir and piperacillin was initiated. However, after 1 week of treatment, the infiltration shadows on chest X-ray had worsened. Because the expectorated sputum collected on admission for culture was found to be positive for Nocardia spp., piperacillin was replaced with trimethoprim/sulfamethoxazole, and a chest X-ray showed some improvement.Although pulmonary nocardiosis with co-infection with influenza A is extremely rare, clinicians should be alert to the possibility.     

European Cystic Fibrosis Society Standards of Care: Framework for the Cystic Fibrosis Centre

A significant increase in life expectancy in successive birth cohorts of people with cystic fibrosis (CF) is a result of more effective treatment for the disease. It is also now widely recognized that outcomes for patients cared for in specialist CF Centres are better than for those who are not. Key to the effectiveness of the specialist CF Centre is the multidisciplinary team (MDT), which should include consultants, clinical nurse specialist, microbiologist, physiotherapist, dietitian, pharmacist, clinical psychologist, social worker, clinical geneticist and allied healthcare professionals, all of whom should be experienced in CF care. Members of the MDT are also expected to keep up to date with developments in CF through continued professional development, attendance at conferences, auditing and involvement in research. Specialists CF Centres should also network with other Centres both nationally and internationally, and feed Centre data to registries in order to further the understanding of the disease. This paper provides a framework for the specialist CF Centre, including the organisation of the Centre and the individual roles of MDT members, as well as highlighting the value of CF organisations and disease registries.
