Objective To summarize the progress of the application of ultrasound-guided thermal ablation for treatment of papillary thyroid microcarcinoma (PTMC). Methods The relevant literatures of thyroid nodules treated by ultrasound-guided thermal ablation were reviewed by adopting the methods of literature review. Results In conditions of grasping the therapeutic indication strictly and evaluating preoperative various aspects sufficiently, it reveals a certain feasibility and validity applying ultrasound-guided thermal ablation in the treatment of PTMC classified in the low-risk group. Conclutions Possessing the advantages of minimal invasive techniques, low-risks, beauty and rapidness, ultrasound-guided thermal ablation might be recommended as an alternative to a low-risk PTMC patient who is at high risk in general anaesthesia operation or intolerant to open operation.
ObjectiveTo evaluate the effectiveness of different biopsy methods in the diagnosis of idiopathic interstitial pneumonia (IIP). MethodsA retrospective analysis was performed in patients hospitalized and diagnosed as IIP between January 2010 to December 2013 in the Department of Respiratory Medicine, the First Affiliated Hospital of Guangzhou Medical University. The patients were divided based on initial diagnoses. The performance of invasive examinations including both transbronchoscopic lung biopsy (TBLB) and surgical lung biopsy (SLB) and final diagnoses were recorded. ResultsThree hundred and ninety-one patients were included in the study with mean age of 62.5±11.9 years. There were 299 patients receiving TBLB, 43 patients receiving SLB, and 49 patients receiving non-invasive examinations. Among 299 patients who underwent TBLB, parenchymal tissue was not obtained in 132 (44.1%) but successfully obtained in 167 (55.9%) patients, with 79 (47.3% out of 167) clinically helpful. TBLB-based specific diagnoses were as follows:30 cases of non-specific interstitial pneumonia (NSIP), 22 cases of cryptogenic organizing pneumonia (COP), 18 cases of idiopathic pulmonary fibrosis (IPF), 4 cases of acute interstitial pneumonia (AIP), 2 cases of respiratory bronchiolitis-interstitial lung disease (RB-ILD) and lymphocytic interstitial pneumonia (LIP) for each, 1 case of desquamative interstitial pneumonia (DIP), respectively. Among 43 patients who underwent SLB, parenchymal tissue was obtained in all cases with 40(93.0% out of 43) pathologically diagnostic, including 20 cases of NSIP, 12 cases of IPF, 3 cases of COP and LIP for each, and 2 cases of RB-ILD and DIP for each. Finally, among 181 patients who failed to obtain parenchymal tissue or did not undergo invasive examination, specific diagnoses could be established in 40 patients with all finally diagnosed as IPF. ConclusionsThe pathological diagnosis, either based on TBLB or SLB, is very important in the diagnostic procedure of IIP. The biopsy technique of hospital and patient conditions should be considered when making the decision of biopsy method.
ObjectiveTo systematically review the risk factors of refractory mycoplasma pneumoniae pneumonia (RMPP) in children. MethodsPubMed, The Cochrane Library, EMbase, CNKI, CBM, VIP, and WanFang Data databases were electronically searched for case-control studies and cohort studies on the risk factors of RMPP in children from inception to March 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software. ResultsA total of 27 case-control studies involving 3 967 children with RMPP and 11 613 children with common MPP were included. The results of meta-analysis showed that heat course (OR=2.07, 95%CI 1.98 to 2.16, P<0.000 01), length of hospital stay (OR=1.42, 95%CI 1.14 to 1.69, P<0.000 01), recurrent respiratory tract infection (OR=8.51, 95%CI 6.15 to 11.77, P<0.000 01), level of IL-6 (OR=21.95, 95%CI 20.85 to 23.06, P<0.000 01), level of CRP (OR=2.41, 95%CI 1.94 to 2.87, P<0.000 01), level of LDH (OR=0.79, 95%CI 0.53 to 1.06, P<0.000 01), level of ESR (OR=2.65, 95%CI 1.13 to 4.18, P=0.000 6), combined pleural effusion (OR=9.42, 95%CI 3.65 to 24.31, P<0.000 01), combined with extrapulmonary complications (OR=3.33, 95%CI 2.42 to 4.58, P<0.000 01), large lung consolidation (OR=12.31, 95%CI 5.42 to 27.99, P<0.000 01) were the risk factors for RMPP. ConclusionsCurrent evidence indicates that heat course, length of hospital stay, repeated respiratory tract infection, high level of IL-6, high level of CRP, high level of LDH, high level of ESR, combined pleural effusion, combined extrapulmonary complications, and large lung consolidation are risk factors for children with RMPP. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
