J Korean Med Sci 2023; 38:e348. [PMID: 38050909 PMCID: PMC10695755 DOI: 10.3346/jkms.2023.38.e348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Accepted: 09/07/2023] [Indexed: 12/07/2023] Open
Abstract
BACKGROUND Paradoxical responses (PR) occur more frequently in lymph node tuberculosis (LNTB) than in pulmonary tuberculosis and present difficulties in differential diagnosis of drug resistance, new infection, poor patient compliance, and adverse drug reactions. Although diagnosis of mediastinal LNTB has become much easier with the development of endosonography, limited information is available. The aim of this study was to investigate the clinical course of mediastinal LNTB and the risk factors associated with PR. METHODS Patients diagnosed with mediastinal LNTB via endosonography were evaluated retrospectively between October 2009 and December 2019. Multivariable logistic regression was applied to evaluate the risk factors associated with PR. RESULTS Of 9,052 patients who underwent endosonography during the study period, 158 were diagnosed with mediastinal LNTB. Of these, 55 (35%) and 41 (26%) concurrently had pulmonary tuberculosis and extrapulmonary tuberculosis other than mediastinal LNTB, respectively. Of 125 patients who completed anti-tuberculosis treatment, 21 (17%) developed PR at a median of 4.4 months after initiation of anti-tuberculosis treatment. The median duration of anti-tuberculosis treatment was 6.3 and 10.4 months in patients without and with PR, respectively. Development of PR was independently associated with age < 55 years (adjusted odds ratio [aOR], 5.72; 95% confidence interval [CI], 1.81-18.14; P = 0.003), lymphocyte count < 800/μL (aOR, 8.59; 95% CI, 1.60-46.20; P = 0.012), and short axis diameter of the largest lymph node (LN) ≥ 16 mm (aOR, 5.22; 95% CI, 1.70-16.00; P = 0.004) at the time of diagnosis of mediastinal LNTB. CONCLUSION As PR occurred in one of six patients with mediastinal LNTB during anti-tuberculosis treatment, physicians should pay attention to patients with risk factors (younger age, lymphocytopenia, and larger LN) at the time of diagnosis.

[PMID: 34481209 DOI: 10.1016/j.lungcan.2021.08.016] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 08/02/2021] [Accepted: 08/26/2021] [Indexed: 12/25/2022]
Abstract
OBJECTIVES Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become a standard procedure, but little is known about its infectious complications. The aim of this study is to evaluate the incidence and risk factors of infectious complications of EBUS-TBNA and its clinical course, including effects on anti-cancer treatment. METHODS This is a nested case-control study of patients who received EBUS-TBNA and were followed for at least 2 months at Samsung Medical Center from August 2009 to April 2019. Patients with clinical symptoms of infection and correlating chest images were defined as the infection group (n = 33). The controls were randomly selected from patients without infectious complication. Multivariate logistic regression with backward selection was used to identify the risk factors of infectious complications. RESULTS Of the 6826 patients, 33 (0.48%) infectious complications were identified, comprising pneumonia (n = 20) and mediastinal infections (n = 13). Target lesions with necrotic features on chest computed tomography (CT) scan (adjusted odds ratio [aOR], 3.08; 95% confidence interval [CI], 1.49-6.40; P = 0.002) and procedures that were performed via the esophagus (aOR, 3.19; 95% CI, 1.47-6.88; P = 0.003) were independently associated with infectious complications. Among patients ultimately diagnosed with cancer, the infection group tended to refuse anti-cancer treatment compared to controls (32/459, 7.0% vs. 5/30, 16.7%; P = 0.066). However, among the patients who received anti-cancer treatment, there was no delay in onset of treatment. CONCLUSIONS Infectious complications of EBUS-TBNA are rare; however, attention should be paid if the target lesion appears necrotic on chest CT or if the procedure is performed via the esophagus. Although it was not conclusive due to its rarity, patients with infectious complications tended not to receive anti-cancer treatment.

Respir Med Res 2021; 79:100825. [PMID: 33971432 DOI: 10.1016/j.resmer.2021.100825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Revised: 03/29/2021] [Accepted: 03/31/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND Pulmonary tuberculosis (TB) is the most frequent site of TB and the one leading its spread worldwide. Multiple specimens are commonly collected for TB diagnosis including those requiring invasive procedures. This study aimed to review the sampling strategy for the microbiological diagnosis of pulmonary TB. METHODS A retrospective analysis of collected samples from September 1st 2014 to May 1st 2016 in the Bacteriology laboratory of Pitié-Salpêtrière Hospital (Paris, France) was performed. All the samples collected in patients aged over 18 years for the bacteriological diagnosis of pulmonary TB were included. RESULTS A total of 6267 samples were collected in 2187 patients. One hundred and twenty-six patients (6%) had a culture confirmed pulmonary TB. Among them, multiple sputum collections were sufficient for TB diagnosis in 63.5%, gastric lavages permitted to avoid bronchoscopy in only 7.1%, and bronchoscopy was necessary in 29.4%. The culture positivity of sputa (8.6%) was higher than that of bronchial aspirations (3.1%), bronchiolo-alveolar lavages (BAL) (2.3%) or gastric lavages (4.8%) (P<0.001). From its 70.0% theoretical PPV value, the 46.1% selection in bronchial aspirations allocated to molecular test increased PPV up to 88.9%. CONCLUSIONS Based on our data, we suggest to collect sputum consistently. If smear negative a bronchoscopy should be performed and molecular diagnosis be performed on a subset of bronchial aspirations based on expertise of the bronchoscopist.

Abstract
OBJECTIVES The practice of cytopathology has evolved over the past decade with a growing need for doing more with less tissue. Changes in clinical practice guidelines and evolving needs in tissue acquisition for diagnosis and treatment have affected various areas of cytopathology in different ways. In this study, we evaluated the changing trends in cytopathological practice at our institution over the past decade. METHODS We performed a retrospective review of our institutional database for cytopathology cases from calendar years 2009 (n = 28038) and 2019 (n = 31386) to evaluate the changing trends in practice. RESULTS The overall number of exfoliative cases decreased 10% over the past decade, primarily due to a 64% decrease in gynaecological Pap testing. However, the volume of serous body cavity and cerebrospinal fluids increased 125% and 44%, respectively. The overall volume of fine needle aspiration (FNA) cases increased 38% from 2009 to 2019. The number of FNA cases increased across most body sites, driven primarily by a 180% increase in endobronchial ultrasound-guided transbronchial needle aspiration cases. In contrast, breast FNA volume decreased 43%. Ancillary studies increased substantially over the past decade, including immunostains (476%) and molecular testing (250%). CONCLUSIONS The trends in our cytopathological practice showed an increased volume of cases, especially in non-gynaecological specimens. As expected, the number of FNA cases used for immunostains and molecular testing increased substantially, indicating an upward trend in ancillary studies in cytopathological practice.

Abstract
Convex probe endobronchial ultrasound (CP-EBUS) has been widely used in the lymph node staging and restaging of lung tumors and the diagnosis of mediastinal diseases. Recent years have seen continuous progress in this technology. For diagnosis, elastography technology can preliminarily distinguish between benign and malignant lesions, so that reduce the number of punctures. CP-EBUS can also be used as an endoscopic ultrasound (EUS) to guide needle aspirations of liver lesions, retroperitoneal lymph nodes and left adrenal gland (LAG) lesions sometimes. Some advances help diagnosing more accurately and effectively, such as the intranodal forceps biopsy (IFB), the new type of 22G needle, the rapid on-site evaluation (ROSE) and the cancer gene methylation, etc. In addition, special advances are being made in diagnosis using artificial intelligence (AI). For treatment, CP-EBUS has yielded novel research results when applied to transbronchial needle injection (TBNI) and radioactive seed implantation in clinical cases, and blocking of the cardiac plexus in animal studies. The next-generation CP-EBUS is also ready for use in the clinic and the technology will be improving continuously. Through this review, we hope to educate clinicians on the latest uses of CP-EBUS and open up further research ideas for readers interested in this technology.

Abstract
Background and Objectives: The application of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been markedly increased over the past decade. EBUS-TBNA is known to be a very safe and accurate procedure; however, the incidence of bleeding complications in patients who are taking antithrombotic agents (ATAs) is not well established. Materials and Methods: We conducted a retrospective analysis of a prospectively registered EBUS-TBNA cohort in a single tertiary hospital from May 2009 to December 2016. The patients were divided into two groups: an insufficient discontinuation group, defined as having a prescription for ATAs on the procedure day or only interrupting them for a short period of time, and a sufficient discontinuation group, defined as having prescription for ATAs during 30 days prior to the procedure and interrupting them for a sufficient period of time. Results: During the study period, a total of 4271 patients, after excluding 3773 patients who did not take ATAs at all, 498 patients were classified into the insufficient discontinuation group (n = 102) and the sufficient discontinuation group (n = 396). The baseline characteristics of patients and examined lesions between two groups were not significantly different, except insufficient discontinuation group had longer prothrombin times than the sufficient discontinuation group. In the insufficient discontinuation group, the most common reasons for prescriptions of ATAs were ischemic heart disease (48.0%) and cerebral vascular disease (28.4%), and half of the patients were taking two or more ATAs. Eventually, only one bleeding complication in the insufficient discontinuation group (1/102, 1.0%) and one event in the sufficient discontinuation group (1/396, 0.3%) occurred (p = 0.368). Conclusions: EBUS-TBNA is considered a safe procedure in terms of bleeding complications, even in patients with insufficient stopping of ATAs.

Abstract
SETTING Although endobronchial ultrasonography-transbronchial needle aspiration (EBUS-TBNA) has a well-known place in the staging and diagnosis of lung cancer, the place of EBUS is not clear in the diagnosis of benign diseases, especially in countries with a high prevalence of tuberculosis. AIM The aim of this study is to investigate the diagnostic efficacy of EBUS-TBNA in benign diseases in a population with a high prevalence of tuberculosis. MATERIAL AND METHODS Between October 2011 and March 2018, 1077 EBUS-TBNA was applied. RESULTS The diagnosis was reached with mediastinoscopy or video assisted thoracic surgery (VATS) in 41 (74.5%) and with the second EBUS-TBNA performed in 14 (25.5%) of 55 EBUS practices in 41 patients with malignancy diagnosis. The final diagnosis was achieved with clinical/radiological features in 7 (77.7%) cases of sarcoidosis, with VATS/mediastinoscopy in 2 (22.2%) cases, with EBUS-TBNA performed for the second time in 6 (54.5%) tuberculosis cases and with acid-resistance bacilli reproduction in Lowenstein-Jensen culture in 5 (45.4%) cases. Two hundred and ninety-five (79.7%) patients were accepted as "benign disease" due to the absence of radiological and clinical progression of lesions in the follow-up. CONCLUSION The diagnostic accuracy of EBUS-TBNA is high in benign diseases such as sarcoidosis and tuberculosis.

Abstract
PURPOSE The diagnosis of pulmonary fungal infections is challenging due to the difficulty of obtaining sufficient specimens. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) needle rinse fluid has become an emerging diagnostic material. This study evaluated the role of routine fungal culture from EBUS-TBNA needle rinse fluid, in addition to histopathologic examination and fungal culture of EBUS-TBNA core tissue, in the diagnosis of pulmonary fungal infections. MATERIALS AND METHODS Among patients who underwent EBUS-TBNA, those with results for at least one of three tests (histopathologic examination, fungal culture of EBUS-TBNA core tissue or needle rinse fluid) were included. Patients with a positive test were divided into two groups (clinical fungal infection and suspected fungal contamination) according to their clinical assessment and therapeutic response to antifungal. RESULTS Of 6072 patients, 41 (0.7%) had positive fungal tests and 9 (22%) were diagnosed as clinical fungal infection. Of the 5222 patients who were evaluated using a fungal culture from EBUS-TBNA needle rinse fluid, 35 (0.7%) had positive results. However, only 4 out of 35 (11.4%) were classified as clinical fungal infection. Positive results were determined in 4 of the 68 (5.9%) evaluated by a fungal culture of EBUS-TBNA core tissue, and all were diagnosed as clinical fungal infection. CONCLUSION Routine fungal culture of EBUS-TBNA needle rinse fluid is not useful due to the low incidence of fungal infection and high rate of contamination. However, fungal culture of EBUS-TBNA core tissue and needle rinse fluid should be considered in patients with clinically suspected fungal infection.
