Clinical manifestations, computed tomography features, management and prognosis of Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism

Objective To explore the clinical manifestations, computed tomography features, management and prognosis of Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism. Methods The clinical data of patients with Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism admitted to Dongnan Hospital of Xiamen University from January 2012 to January 2017 were retrospectively analyzed. Results There were 8 patients who had Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism. Fever occurred in all patients, respiratory symptoms were noted in 5 patients, abdominal pain occurred in 2 patients, endophthalmitis coexisted in 1 patient, and diabetes mellitus coexisted in 7 patients, with no chest pain or hemoptysis. In biochemical indexes, procalcitonin increased most obviously. Microbiological studies revealed Klebsiella pneumoniae in 8 patients. Chest CT showed peripheral nodules with or without cavities, peripheral wedge-shaped opacities, a feeding vessel sign, pleural effusion, and infiltrative shadow. One patient finally deteriorated to acute respiratory failure, and died due to acute respiratory distress syndrome and/or septic shock. There was one case of spontaneous discharge. A total of 6 patients were improved and cured. Conclusions The clinical manifestation of Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism is unspecific and misdiagnosis rate is relatively high. The major characteristics of chest CT scan include peripheral nodules with or without cavities, peripheral wedge-shaped opacities and a feeding vessel sign. Diagnosis and differential diagnosis can be made based on these features combined with clinical data and primary disease (liver abscess).

Efficacy of Bronchial Arterial Embolization in Treatment of Massive Hemoptysis due to Bronchiectasis: 205 Cases Analysis

Objective To evaluate the clinical effects of bronchial artery embolization ( BAE) for massive hemoptysis due to bronchiectasis.Methods 205 patients with massive hemoptysis were treated with bronchial artery embolization using coils, polyvinyl alcohol ( PVA) microspheres, line segmen, and gelatin sponge after the site of bleeding or the abnormal arteries were identified by arteriography. Super selective bronchial artery embolization was performed with a coaxial microcatheter inserted into the bronchial artery. Results BAE was successfully performed in 205 cases with massive hemoptysis ( left and right bronchial artery embolization in 35 cases, left bronchial artery embolization in 20 cases, right bronchial artery embolization in 126 cases, common bronchial artery embolization in 22 cases, right inferior phrenic artery embolization in 2 cases) . Of 205 patients, 169 were cured, 24 were relieved with a success rate of 94.1% . Long termcumulative hemoptysis nonrecurrence rates was 82.4% . 23 patients developed post embolization syndrome characterized by mild fever and chest pain and ended with spontaneous recovery without special management. No severe complications including spinal cord injury or dystopia embolization were observed. Conclusions Bronchial arterial embolization interventional therapy is a rapid, safe and effective method in the treatment of massive hemoptysis due to bronchiectasis.

Research progress on the pathogenesis of ischemic bile duct injury after liver TACE

ObjectiveTo summarize the research progress on the pathogenesis of ischemic bile duct injury after transcatheter arterial chemoembolization (TACE).MethodThe recent studies on the incidence, pathological features and related mechanisms of ischemic bile duct injury and ischemic bile duct injury after TACE were reviewed.ResultsThe incidence of ischemic bile duct injury after liver TACE fluctuated greatly and was related to different chemoembolization methods. At present, the causes of ischemic bile duct injury were attributed to the bile duct ischemia caused by embolization and the toxic effects of chemotherapeutic drugs. The destruction of protective mechanism of bile duct epithelium and the expression of transforming growth factor-β might play an important role in ischemic bile duct injury.ConclusionsAfter liver TACE, in addition to the direct injury of bile duct caused by the toxic effects of ischemia and chemotherapy drugs, the damage of bile duct epithelial protection mechanism caused by ischemia and chemotherapy drugs makes the toxic effects of bile acids play a very important role in the ischemic bile duct injury. However, there is still no direct evidence of bile duct epithelial protection mechanism in ischemic bile duct injury after liver TACE. Further clarifying the role of bile duct epithelial protection mechanism in ischemic bile duct injury after liver TACE will be helpful to explore its prevention and treatment measures, and provide new insights for the further studies in future.

Effects of Combined TACE and PVC for Primary Hepatocellular Carcinoma: Meta-Analysis

ObjectiveTo evaluate the effects of combined TACE and PVC regarding the survival and diseasefree survival rate in hepatocellular carcinoma (HCC) patients. MethodsThe relevant articles were searchd by a database search of PubMed, EMBASE, Cochrane Library (CENTRAL) Databases, Web of Science, Sciencedirect, National Institute of Health Clinical Trials Database, CNKI, WANFANG Database, and VIP Database. The analysis of the data was performed using Revman 5.1 Software. ResultsBy searching and selecting, a total of ten articles met the inclusion criteria, of which 6 were in the postoperative group, and 4 were in the no-operative group. There were no statistical significance of heterogeneity in each group through subgroup analyzed. The pooled OR showed that combined TACE and PVC could significantly increase the 1-, 2-, and/or 3-year survival and disease-free survival rates compared with TACE alone for HCC patients. The pooled OR and 95% CI of the 1-, 2-and/or 3-year survival and disease-free survival rate, respectively, were as follows:In operative group, 1-year disease-free survival rate 2.09, 1.21-3.61; 3-year disease-free survival rate 3.62, 1.88-6.97; 1-year survival rate 2.25, 1.30-3.87; 3-year survival rate 1.96, 1.20-3.21. In no-perative group:1-year survival rate 3.90, 2.33-6.54; 2-year survival rate 5.30, 1.87-15.06. Conlusions Compared with TACE alone, postoperative adjuvant combined TACE and PVC can significantly increase the 1-, and 3-year survival and disease-free survival rates. For no-perative group, adjuvant combined TACE and PVC can significantly increase the 1-, and 2-year survival rates. Based on the limitations of this meta-analysis (this article is included in the high quality literature less), clinicians should be cautious by using our findings.

Interventional embolization, surgery and high intensity focused ultrasound for the treatment of uterine fibroids: a network meta-analysis

ObjectivesTo systematically review the safety and effectiveness of uterine artery embolization (UAE), surgery and high intensity focused ultrasound (HIFU) in the treatment of uterine fibroids.MethodsPubMed, EMbase, The Cochrane Library, Web of Science, WanFang Data and CNKI databases were electronically searched to collect relevant studies on comparing the safety and effectiveness of UAE, surgery and HIFU in the treatment of uterine fibroids from January 2000 to August 2019. Two reviewers independently screened the literature, extracted the data and evaluated the risk of bias of included studies, network meta-analysis was performed by ADDIS 1.16.8 software and Stata 14.0 software.ResultsA total of 11 trials (22 references) involving 3469 patients were included. Compared with surgery, UAE and HIFU patients had higher quality of life (1-year follow-up) improvement, and UAE was higher than HIFU. Network meta-analysis showed that patients treated with HIFU had the lowest incidence of major complications within 1 year, followed by UAE, and surgery. Patients treated with HIFU and UAE had shorter hospitalization and quicker recovery time than surgery. The rate of further intervention after surgery treatment might be lower than that of UAE and HIFU.ConclusionsUAE has the highest quality of life improvement (1-year follow-up) for uterine fibroids. HIFU and UAE are safer with shorter hospital stays and quicker recovery time compared with surgery. However, both UAE and HIFU have the risk of re-treatment. However, limited by the number and quality of included studies, the above conclusions are needed to be verified by more high-quality studies.

Effect of Preoperative Gastric Arterial Chemoembolization on Apoptosis of Lymph Node Metastasis of Gastric Cancer

【Abstract】ObjectiveTo study the effect of preoperative gastric arterial chemoembolization on apoptosis of lymph node metastasis of gastric cancer. MethodsForty patients with gastric cancer and lymph node metastasis underwent curative resection, among which there were 20 patients who received the preoperative gastric arterial chemoembolization, and they constituted the treatment group. The rest of the patients were included in the control group. The expressions of p53, CD95 and bcl-2 were examined by immunohistochemistry and apoptosis in the lymph node metastasis was examined by in situ terminal transferasemediated dUTP nick end labeling （TUNEL）. ResultsThe expression intensity of p53 and CD95 in lymph node metastasis of treatment group increased more significantly than that of control group, whereas the expression intensity of bcl-2 decreased in treatment group. There was a significantly positive correlation between the expressions of p53 and CD95 and the apoptosis.ConclusionPreoperative gastric arterial chemoembolization may affect the expressions of p53, CD95 and bcl-2 and may induce the apoptosis of lymph node metastasis. It may be helpful to improve the effect of curative resection of gastric cancer.
