Abstract
INTRODUCTION Lymphobronchial tuberculosis (TB) is common in children with primary TB and enlarged lymph nodes can cause airway compression of the large airways. If not treated correctly, airway compression can result in persistent and permanent parenchymal pathology, as well as irreversible lung destruction. Bronchoscopy was originally used to collect diagnostic samples; however, its role has evolved, and it is now used as an interventional tool in the diagnosis and management of complicated airway disease. Endoscopic treatment guidelines for children with TB are scarce. AREAS COVERED The role of interventional bronchoscopy in the diagnosis and management of complicated pulmonary TB will be discussed. This review will provide practical insights into how and when to perform interventional procedures in children with complicated TB for both diagnostic and therapeutic purposes. This discussion incorporates current scientific evidence and refers to adult literature, as some of the interventions have only been done in adults but may have a role in children. Limitations and future perspectives will be examined. EXPERT OPINION Pediatric pulmonary TB lends itself to endoscopic interventions as it is a disease with a good outcome if treated correctly. However, interventions must be limited to safeguard the parenchyma and prevent permanent damage.

Abstract
Tuberculosis (TB) is the leading cause of death from a single infectious agent globally. Mortality is related to the delay in diagnosis and starting treatment. According to new guidelines it is very important to classify pulmonary tuberculosis (PTB) as severe or not severe disease due to the difference in treatment duration. Bronchoscopy is the gold standard for assessing the degree of airway compression and obstruction in paediatric PTB. Paediatric bronchoscopy has evolved from a primarily diagnostic procedure to include interventional bronchoscopy for diagnostic purposes. Endobronchial ultrasound (EBUS) has increased the potential of sampling mediastinal lymph nodes both for histological diagnosis and microbiological confirmation.

Abstract
OBJECTIVE To study bronchoalveolar lavage (BAL) findings in various respiratory diseases in children in Kashmir India. DESIGN Prospective observational study. SETTING Paediatric department of the tertiary care hospital. PATIENTS Children of both genders from 1 month to 17 years of age INTERVENTION: All studied patients underwent flexible bronchoscopy and BAL. OUTCOME MEASURE To observe the BAL findings in various respiratory diseases in the studied population. RESULTS A total of 283 patients underwent BAL procedure. The positive BAL report was received in 131 (46%) patients. Out of these, 55 (42%) patients had positive BAL culture/ microscopy for different bacterial (50) and fungal species (Candida spp (3), Mucormycosis (1) and Aspergillus (1)). MTB was isolated in 25 (19%) patients. Twenty-three (17.5%) patients had bronchoalveolar lavage fluid (BALF) positive for pulmonary hydatidosis. Foamy macrophages were seen in 13 patients, significant eosinophilia in nine patients and hemosiderin-laden macrophages were seen in three patients. CONCLUSION We found BALF a very useful sample for the evaluation of many infective and non-infective respiratory diseases in our region, which otherwise lacks high end diagnostics. 46% of our patients had some abnormalities in the BAL specimen. It provided us with valuable information regarding organism profile and drug sensitivity in case of lung infection. BALF analysis was also found useful in the diagnosis of some non-infective pulmonary disorders like acute eosinophilic pneumonia, aspiration syndromes and bronchial asthma.

Diagnostic Yield of Xpert MTB/RIF Assay Using Bronchoalveolar Lavage Fluid in Detecting Mycobacterium tuberculosis among the Sputum-Scarce Suspected Pulmonary TB Patients. Diagnostics (Basel) 2022; 12:diagnostics12071676. [PMID: 35885580 PMCID: PMC9324532 DOI: 10.3390/diagnostics12071676] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 06/26/2022] [Accepted: 06/27/2022] [Indexed: 11/16/2022] Open
Abstract
Tuberculosis (TB) remains one of the leading causes of death worldwide and is caused by the single infectious agent Mycobacterium tuberculosis (Mtb). Although sputum is the most common specimen for pulmonary TB detection, some other respiratory specimens, such as bronchoalveolar lavage (BAL) fluid, gastric lavage (GL), and induced sputum (IS), are also collected from patients who are unable to deliver sputum. In this study, we aimed to evaluate the diagnostic performances of different test methods for TB diagnosis using BAL fluid specimens from sputum-scarce pulmonary TB patients. In this current study, a total of 210 BAL fluid specimens were collected and subjected to culture on Lowenstein–Jensen (L-J) medium, using an N-acetyl-L-cysteine-Sodium Hydroxide decontamination and digestion method, Xpert MTB/RIF (Xpert, Cepheid, Sunnyvale, CA, USA) assay, and acid-fast bacilli (AFB) microscopy with a Ziehl–Neelsen staining method for the detection of pulmonary TB. The sensitivity and specificity of these methods were then analyzed against the composite reference standard (CRS). Additionally, the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of these assays. Among the 210 specimens, 39 (18.6%), 27 (12.8%), and 12 (5.7%) were found positive with Xpert assay, culture, and AFB microscopy, respectively. Considering the CRS, 42 (20%) were positive as the final diagnosis. The Xpert assay had a significantly higher sensitivity (92.9%, 95% CI: 80.5–98.5) compared to culture (64.3%, 95% CI: 48.0–78.4) and AFB microscopy (28.6%, 95% CI: 15.7–44.6) against the CRS. Additionally, the area under the ROC curve (AUC) for the Xpert assay, culture, and AFB microscopy accounted for 0.964, 0.821, and 0.655, respectively, when using CRS as the reference. In conclusion, our study findings demonstrated that the Xpert assay conferred a considerable diagnostic potential compared to other conventional methods for the diagnosis of pulmonary TB from BAL fluid specimens.

Abstract
Bronchoscopy is useful as a diagnostic and therapeutic procedure in children with Tuberculosis (TB) disease complicated by airway obstruction. It is needed in children when surgical intervention may be required for airway compression, when drug resistance is suspected, and to rule out an alternative diagnosis for airway obstruction. Bronchoscopy with bronchoalveolar lavage (BAL) should be performed when other, less invasive samples cannot be collected, or when they fail to provide useful diagnostic information. BAL specimens collected at bronchoscopy can be tested using molecular TB assays and mycobacterial culture. The aim of this review is to evaluate the role of bronchoscopy in the diagnosis and management of pulmonary TB in children, and, specifically, to review the role of interventional bronchoscopy. A search of electronic databases was undertaken using the online databases PubMed, Ovid MEDLINE, EMBASE, Google Advanced Scholar, and Web of Science to identify relevant literature. The search was limited to pediatrics, pulmonology, bronchoscopy, and pediatric pulmonary tuberculosis for all articles published in English on pediatric bronchoscopy between 2010 and 2020. Recent advances in pediatric bronchoscopy was included, as well as recent research on improving the diagnosis with the use of interventional bronchoscopy. The role of bronchoscopy in pediatric pulmonary tuberculosis has changed during the last decade, from a simple method of collecting samples for bacteriological conformation to an more sophisticate procedure. New methods are available for collecting samples, which includes the use of Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and also better methods of bacteriological conformation. Interventions are now possible; not only to improve the diagnostic abilities of bronchoscopy but also to diagnose, manage, and follow-up upon airway-related complications. Bronchoscopy services remain limited in resource-limited countries due to the high cost of equipment.

Abstract
The diagnosis of childhood tuberculosis is a challenge due to the pauci-bacillary nature of infection and the difficulty in obtaining appropriate sample. In the past 2-3 decades, many new tests were introduced for the diagnosis of tuberculosis (TB) and some of them have been evaluated for their application in pediatric tuberculosis as well. There is an attempt to improve smear microscopy by introducing light-emitting diode (LED) fluorescence microscopy and there are also some automated digital microscopy platforms under evaluation. Introduction of automated liquid culture platform along with rapid molecular based identification methods have considerably reduced the time delay in mycobacterial culture. Recent addition of many nucleic acid amplification platforms like Amplicor PCR, Genprobe, Xpert MTB/Rif, line probe assays, loop mediated isothermal amplification etc are also been found to be useful. Latest techniques like microarray and gene sequencing are also being used in clinical laboratories with variable results. Indirect methods of TB diagnosis like T cell based assays including tuberculin skin test and interferon-gamma release assays have their role primarily in the diagnosis of latent TB. Biomarkers are the latest addition in the battery of TB diagnostic tests facilitating diagnosis using easily accessible samples like urine, blood and breath of patients. Many biomarkers are still under evaluation and some of them are found to have a potential role as promising diagnostic tests of future.

Abstract
PURPOSE Interventional pulmonology is a growing subspecialty of pulmonary medicine with flexible and rigid bronchoscopies increasingly used by interventional pulmonologists for advanced diagnostic and therapeutic purposes. This review discusses different technical aspects of anesthesia for interventional pulmonary procedures with an emphasis placed on pharmacologic combinations, airway management, ventilation techniques, and common complications. SOURCE Relevant medical literature was identified by searching the PubMed and Google Scholar databases for publications on different anesthesia topics applicable to interventional pulmonary procedures. Cited literature included case reports, original research articles, review articles, meta-analyses, guidelines, and official society statements. PRINCIPAL FINDINGS Interventional pulmonology is a rapidly growing area of medicine. Anesthesiologists need to be familiar with different considerations required for every procedure, particularly as airway access is a shared responsibility with pulmonologists. Depending on the individual case characteristics, a different selection of airway method, ventilation mode, and pharmacologic combination may be required. Most commonly, airways are managed with supraglottic devices or endotracheal tubes. Nevertheless, patients with central airway obstruction or tracheal stenosis may require rigid bronchoscopy and jet ventilation. Although anesthetic approaches may vary depending on factors such as the length, complexity, and acuity of the procedure, the majority of patients are anesthetized using a total intravenous anesthetic technique. CONCLUSIONS It is fundamental for the anesthesia provider to be updated on interventional pulmonology procedures in this rapidly growing area of medicine.

Abstract
AIM The aim of this research is to show why is it important in diagnosing children with lung infiltrates. METHODS Our study included 50 children with lung infiltrates during period 2005-2012, and was conducted on Pediatric Clinic of the University Clinical Center Sarajevo. We sent all cytological BAL analyses to the University Clinical Center Sarajevo. Cytology was performed by direct microscopy. BAL cytology was performed by the principle of sending samples for centrifuging, 12000 revolutions during a 10 min Shandon-cyto spin. Then the centrifuged sample is dried in the air during 1-2 hours, and is then dyed under the May-Grünwald-Giemsa staining, and analyzed under the Olympus BX41 microscope. RESULTS Nosocomial pneumonia has occurred in 32% children, acquired pneumonia in 38%, and 30% children had a lung infiltrates. 6 (12%) of children were younger then 1 year old, 23 (46%) children were between 1 to 5 years, 14 (28%) of children were between 5 to 10 ages, and 7 (14%) of children were between 10-15 ages. The most of the changes in observed children took place on the right lung, 34%, while 26% occurred on the left side, 22% were normal and 18% changes have affected both lungs, right and left. Percentage of cells in cytological smear in children with BAL were: cylindrical cells 28%, lung macrophage 26%, lymphocytes 17%, detritus 17% and phlegm 12%. Erythrocyte sedimentation rate (ESR) in children with BAL was up to 10-52%, to 50-30%, while ESR after first hour was above 50-18 %. CONCLUSION Clinical parameters and local inflammation of the affected lobe are associated with positive bronchoalveolar cytology lavage findings.

Abstract
Introduction Seven district-level Nutritional Rehabilitation Centres (NRCs) in Bihar, India provide clinical and nutritional care for children with severe acute malnutrition (SAM). Aim To assess whether intensified case finding (ICF) strategies at NRCs can lead to pediatric case detection among SAM children and link them to TB treatment under the Revised National Tuberculosis Control Programme (RNTCP). Materials and Methods A retrospective cohort study was conducted that included medical record reviews of SAM children registered for TB screening and RNTCP care during July–December 2012. Results Among 440 SAM children screened, 39 (8.8%) were diagnosed with TB. Among these, 34 (87%) initiated TB treatment and 18 (53%) were registered with the RNTCP. Of 16 children not registered under the RNTCP, nine (56%) weighed below six kilograms—the current weight requirement for receiving drugs under RNTCP. Conclusion ICF approaches are feasible at NRCs; however, screening for TB entails diagnostic challenges, especially among SAM children. However, only half of the children diagnosed with TB were treated by the RNTCP. More effort is needed to link this vulnerable population to TB services in addition to introducing child-friendly drug formulations for covering children weighing less than six kilograms.

Abstract
Estimates of the burden of childhood tuberculosis have been hampered by the lack of a reliable diagnostic test. Clinical scoring systems, radiological findings and tuberculin skin testing (the traditional methods used for diagnosis) are unreliable, particularly in the era of HIV. Microbiologic confirmation using induced sputum is feasible and has become increasingly important to define the burden of disease and to enable appropriate treatment. The availability of a rapid molecular diagnostic test (Xpert® MTB/RIF; Cepheid) is an important advance that can improve case detection in children and enable rapid detection of mycobacterial drug resistance. Xpert testing of two induced sputum specimens detected approximately 75% of children with culture-confirmed disease. Urine lipoarabinomannan has shown promise as a rapid diagnostic in a subgroup of HIV-infected severely immunocompromised adults, but there have been no data in children so far. Further research is needed to develop a rapid point-of-care, reliable and affordable diagnostic test for childhood tuberculosis that can be widely used.
