Intraoperative bronchial blood flow evaluation using indocyanine green fluorescence for bronchoplasty: A case report

Introduction and importanceBlood flow evaluation of bronchial arteries using indocyanine green fluorescence (ICG-FL) is rarely reported during pulmonary resection. We present the case of a patient with bronchiectasis and a history of bronchial artery embolization (BAE) for hemoptysis. Bronchial artery blood flow was evaluated using ICG-FL during lobectomy with bronchoplasty.Case presentationA 63-year-old woman presented with right middle lobe bronchiectasis (due to nontuberculous mycobacteriosis) and repeated hemoptysis, which had previously been corrected each time with hemostasis by BAE. Bronchoscopy revealed a swollen blood vessel proximal to the right middle lobe bronchus that was suspected of being the origin of bleeding. Right middle lobectomy with bronchoplasty was performed to prevent hemoptysis. ICG-FL was used to detect the patency of the right bronchial arteries, and the arteries surrounding the right middle lobe bronchus were ligated. The proximal side of the right middle lobe bronchus was cut in a deep wedge shape, and the bronchus was anastomosed. ICG-FL revealed that the blood supply was maintained at the bronchial anastomosis. No bronchial anastomotic leakage was observed after the surgery.Clinical discussionThe key to successful bronchoplasty is the maintenance of blood flow. Bronchial artery blood flow theoretically decreases after BAE. In this case, ICG-FL was able to detect bronchial artery patency before cutting the bronchus as well as the maintenance of blood flow at the bronchial anastomosis after bronchoplasty.ConclusionIntraoperative blood flow evaluation of the bronchus using ICG-FL may reduce the risk of bronchial anastomotic leakage caused by ischemia after bronchoplasty.     

[Translated article] Biological Biomarkers in Respiratory Diseases

In recent years, personalized or precision medicine has made effective inroads into the management of diseases, including respiratory diseases. The route to implementing this approach must invariably start with the identification and validation of biological biomarkers that are closely related to the diagnosis, treatment, and prognosis of respiratory patients. In this respect, biological biomarkers of greater or lesser reliability have been identified for most respiratory diseases and disease classes, and a large number of studies are being conducted in the search for new indicators. The aim of this review is to update the reader and to analyze the existing scientific literature on the existence and diagnostic, therapeutic, and prognostic validity of the most important biological biomarkers in the main respiratory diseases, and to identify future challenges in this area.     

支气管动脉栓塞治疗支气管扩张大咯血28例

目的回顾性分析支气管动脉栓塞治疗支气管扩张大咯血。方法对28例支气管扩张大咯血患者进行选择性支气管动脉造影，用明胶海绵颗粒等材料进行栓塞。结果左支气管动脉栓塞10例，右支气管动脉栓塞12例，左右支气管动脉共干6例。确定出血血管栓塞后，28例患者咯血停止，27例3日内未再咯血，有1例仍有咯血，1周后再行栓塞术后，咯血停止。结论支气管扩张大咯血进行内科保守治疗效果不佳而又无法耐受外科手术者，应及时行支气管动脉造影并栓塞治疗。     

Distribution of Major Pathogens from Sputum and Bronchoalveolar Lavage Fluid in Patients with Noncystic Fibrosis Bronchiectasis: A Systematic Review

Objective:

Noncystic fibrosis (non-CF) bronchiectasis remains as a common health problem in Asia. Pathogens’ distribution in airways of patients with non-CF bronchiectasis is important for doctors to make right decision.

Data Sources:

We performed this systematic review on the English language literatures from 1966 to July 2014, using various search terms included “pathogens” or “bacteria” or “microbiology” and “bronchiectasis” or “non-cystic fibrosis bronchiectasis” or “non-CF bronchiectasis” or “NCFB.”

Study Selection:

We included studies of patients with the confirmed non-CF bronchiectasis for which culture methods were required to sputum or bronchoalveolar lavage fluid (BALF). Weighted mean isolation rates for Haemophilus influenzae, Pseudomonas aeruginosa, Streptococcus pneumoniae, Stapylococcus aureus, Moxarella catarrhails were compared according to different methodology.

Results:

The total mean bacterial culture positive rates were 63%. For studies using sputum samples, the mean positive culture rates were 74%. For studies using BALF alone or BALF and sputum, it was 48%. The distributions of main bacterial strains were 29% for H. influenzae, 28% for P. aeruginosa, 11% for S. pneumoniae, 12% for S. aureus, and 8% for M. catarrhails with methodology of sputum. Meanwhile, the bacterial distributions were 37% for H. influenzae, 8% for P. aeruginosa, 14% for S. pneumoniae, 5% for S. aureus, and 10% for M. catarrhails with methodology of BALF alone or BALF and sputum. Analysis of the effect of different methodology on the isolation rates revealed some statistically significant differences.

Conclusions:

H. influenzae accounted for the highest percentage in different methodology. Our results suggested that the total positive culture rates and the proportion of P. aeruginosa from sputum and BALF specimens had significant differences, which can be used in further appropriate recommendations for the treatment of non-CF bronchiectasis.     

完全型Kartagener综合征二例报道并文献复习

Kartagener综合征是一种临床罕见的常染色体隐性遗传性疾病,发病率极低,主要表现为支气管扩张、慢性鼻窦炎、内脏反位三联征,电镜下纤毛超微结构联合光镜下纤毛功能检查是目前临床诊断Kartagener综合征的“金标准”。本文报道了两例完全型Kartagener综合征患者并进行了文献复习,为进一步提高临床对该病的诊治水平提供参考。     

非囊性纤维化性支气管扩张症的免疫调节机制

支气管扩张症是慢性炎症性支气管疾病的一种,病理上表现为一个或多个支气管的永久性扩张。非囊性纤维化性支气管扩张症的发病往往与反复感染、免疫缺陷或自身免疫性疾病相关,也有相当一部分呈特发性。细菌定植、气道炎症和气道结构损伤这样一个恶性循环导致了支气管扩张症的发生,其中气道炎症承前启后,是整个恶性循环的关键,因此研究气道炎症的免疫调节机制对理解其发病机理具有重要意义,并可指导支气管扩张症的药物研发。本文着重讨论了与支气管扩张症的发病密切相关的细胞与分子免疫调节机理,并阐述了细菌慢性定植的机理,还结合免疫调节讨论了支气管扩张症的新药研发。
