Abstract
PURPOSE To describe a case of a macular tuberculoma in a young and healthy woman after developing a tuberculous lymphadenitis caused by Mycobacterium bovis . METHODS Retrospective case report. RESULTS Tuberculous lymphadenitis caused by M. bovis was detected after biopsy and histological examination as well as polymerase chain reaction test testing of cervical lymph nodes in a 20-year-old patient. An interferon gamma was positive. Shortly starting antitubercular therapy, the patient developed visual deterioration caused by a single yellowish subretinal structure in the macula of the right eye. Optical coherence tomography showed a dome-shaped, hyperreflective, subfoveal choroidal lesion with subtle subretinal fluid. Antitubercular therapy with isoniazid, rifampicin, ethambutol, and pyrazinamide was performed, and the deescalation therapy with isoniazid and rifampicin was extended to 7 months. Further examinations showed regression of choroidal tuberculoma to a scar. CONCLUSION This is the first reported case of choroidal tuberculoma after tuberculous lymphadenitis caused by M. bovis .

Abstract
Tuberculosis is an infectious disease which most commonly compromises the respiratory system, whereas abdominal involvement is rare, thus its diagnosis is a challenge. The clinical manifestations of abdominal tuberculosis as well as its physical examination findings are usually non-specific and, frequently, similar to those of other diseases, so it is critical to consider abdominal tuberculosis among the differential diagnoses. Here we report the clinical case of a 15-year-old male patient hospitalized for a prolonged febrile syndrome associated with abdominal pain, diarrhea, night sweats, and weight loss.

Abstract
CONTEXT Bacillus Calmette-Guérin (BCG) vaccine has been used to prevent tuberculosis and/or its severe complications for long. BCG lymphadenitis is a common complication of the vaccine, which is sometimes subjected to cytological examination. The aim of the study is to describe the cytological findings of BCG lymphadenitis. SETTINGS The study was conducted in a tertiary care hospital in the western part of India from January 2021 to December 2022. DESIGN The study was performed on archived material of all patients who were referred to the fine needle aspiration clinic for cytology examination. Clinical and pathological data of cases were retrieved, and cases of BCG lymphadenitis were selected in the study based on these data. Slides of cases were retrieved, and cytological findings were studied. MATERIALS AND METHODS Papanicolaou, Giemsa, and Hematoxylin & eosin-stained smears, as well as Ziehl-Neelson stain (Z.N. stain) smears of all BCG lymphadenitis cases, were retrieved. Cases were reviewed for individual cytological features and overall cytological diagnostic categories. Z.N. stain smears were evaluated for acid-fast bacilli. RESULTS AND CONCLUSIONS Diagnostic categories observed in BCG lymphadenitis include suppurative lymphadenitis/abscess (15 %), necrotizing lymphadenitis (23 %), necrotizing granulomatous lymphadenitis (46 %), suppurative granulomatous lymphadenitis (8 %), non-necrotizing granulomatous lymphadenitis (8 %). Acid-fast bacilli were detected by Z.N. stain in 8 cases (62 %). The cytological findings of BCG lymphadenitis closely overlap with those of tuberculous lymphadenitis. So, clinical context is very important while reporting isolated axillary lymphadenopathy, specifically in recently vaccinated infants, to avoid misdiagnosis as tuberculous lymphadenitis.

Abstract
BACKGROUND Head and neck lesions of tuberculosis, though not uncommon are often difficult to diagnose and require a unique management protocol. These lesions are often misdiagnosed as bacterial infections, malignancies or other granulomatous diseases. Hence in our study we endeavor to gain a better understanding of the diagnostic and management protocols of tuberculosis in otorhinolaryngology. METHODS We have performed an observational study at our institute, the patient's details were obtained from patient record forms and noted in a standard proforma. Results were calculated as percentage and Chi square analysis was performed. RESULTS We found cervical tuberculous lymphadenitis to be the most common manifestation 76.97%, with a significant association with pulmonary tuberculosis. Neck swelling was the most common presenting complaint, 65.35%. 26-50 years of age was the most commonly involved age group. CONCLUSION FNAC, PCR and histopathology are the modalities for bacteriological diagnosis for tuberculosis of Head and Neck. Anti-tuberculous therapy is uniformly found to be useful in all the patients, with surgical intervention used as and when required.

Abstract
BACKGROUND Nontuberculous mycobacterial cervicofacial lymphadenitis (NTMCL) is an uncommon condition detected in young immunocompetent children who typically present with a nontender neck mass. Various tests have been proposed to assist in the work-up of suspected NTMCL, with varying diagnostic utility. This systematic review investigates the sensitivity of the various diagnostic methods used in the work-up of pediatric NTMCL. METHODS A systematic review in accordance with PRISMA guidelines was performed using the Pubmed, EMBASE, and Web of Science databases. Searches were filtered for English language studies published prior to 05/10/22. Studies meeting criteria included studies featuring 15+ pediatric patients with confirmed or suspected NTMCL. Studies with any reported diagnostic methodology used in the workup of NTMCL were included. RESULTS Of 836 abstracts/articles reviewed, 21 studies met inclusion criteria. Diagnostic methods included culture(n = 11 studies), PPD-Tb(Tuberculin)(n = 12), PPD-Scrofulaceum, -Avium, or -Kansasii(n = 6), staining techniques(n = 4), IGRA(n = 3), and ultrasound(n = 2). All studies had an overall low risk of bias. Among patients confirmed to have NTMCL based on PCR and/or culture, the most sensitive tests were PPD-A(0.94, 95 % CI 0.91 to 0.97; n = 210 patients) and PPD-S(0.75, 95 % CI 0.68 to 0.81; n = 171). Auramine and Ziehl-Neelsen staining techniques had moderately high sensitivity(0.85 and 0.60 respectively), though were limited by low patient numbers(n = 20). PPD-Tb(0.45, 95 % CI 0.39 to 0.50; n = 300) and IGRA(0.02; 95 % CI 0 to 0.06; n = 48) demonstrated poor sensitivity. Among patients suspected to have NTM lymphadenitis based on global assessment, the most sensitive tests included combined PPD-S + A + K(0.92, 95 % CI 0.86 to 0.98; n = 85), PCR(0.82, 95 % CI 0.75 to 0.88; n = 136), and PPD-A(0.72, 95 % CI 0.62 to 0.81; n = 84). Culture showed a sensitivity of 0.54(95 % CI 0.50 to 0.58; n = 494). PPD-K, PPD-S, IGRA, and staining techniques demonstrated lower sensitivity. CONCLUSIONS This systematic review is the largest study investigating the sensitivity of the various diagnostic methods used in the work-up of pediatric NTMCL. Patients with clinical suspicion for NTMCL and a positive PPD-Tb should first have tuberculous lymphadenitis ruled out with IGRA. Patients with a positive PPD-Tb and negative IGRA and high clinical suspicion for NTMCL can undergo presumptive surgical intervention. Patients with a negative PPD-Tb can undergo NTM antigen skin testing if available, or if high clinical suspicion exists, surgical intervention to reduce tissue burden and elicit additional tissue data.

Abstract
INTRODUCTION Lymphadenopathy is usually due to benign or malignant conditions. It can also be local or systemic in distribution and can involve peripheral or deep-seated lymph nodes. This study aimed to determine the prevalence of lymphoma and the distribution pattern of lymph node pathologies among adult patients who presented with lymphadenopathy and its relationship with age and sex. METHODS A retrospective study was conducted, and a record of all cases of lymphadenopathy with histological diagnosis over 5-year period (January 2017 to December 2021) was extracted from Departments of Anatomical Pathology of Alex Ekwueme Federal University Teaching Hospital, Abakaliki. The data generated were analyzed using Statistical Package for Social Sciences (SPSS) software, version 26. RESULTS One hundred and ninety results were extracted with an age range of 18 to 94 years and a mean age of 41 ± 16 years. They were made up of 75 (39.5%) males and 115 (60.5%) females, with a male-to-female ratio of 1:1.5. The prevalence of lymphoma was 50.0% (95/190). Thirty-five (18.4%) were Hodgkin's lymphoma (HL), while 60 (31.6%) were non-Hodgkin's lymphoma (NHL). Other pathologies manifested by cases of lymphadenopathy include metastatic tumor deposits (38 (20%)), reactive lymphoid hyperplasia (29 (15.3%)), and tuberculous lymphadenitis (18 (9.5%)). Others include sinus histiocytosis (4 (2.1%)), dermatopathic lymphadenitis (5 (2.6%)), and Castleman's disease (1 (0.5%)). CONCLUSION About half of all patients who presented with lymphadenopathy were lymphoma with a high prevalence of 50%, and the majority were NHL. Other major causes of lymphadenopathy were metastatic tumor deposits, reactive lymphoid hyperplasia, and tuberculous lymphadenitis. Any case of lymphadenopathy should be properly investigated early for effective management.

Abstract
IMPORTANCE Cervical tuberculous lymphadenitis (CTL), the most frequent extrapulmonary form of tuberculosis, is currently a major health problem in Tunisia and in several regions around the world. CTL diagnosis is challenging mainly due to the paucibacillary nature of the disease and the potential misdiagnosis as cervical non-tuberculous lymphadenitis. This study demonstrates the added value of the heparin-binding hemagglutinin-interferon-gamma release assay as an immunoassay in the context of CTL.

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.

Abstract
Background: Tuberculosis is a chronic infectious disease and can be categorised into pulmonary TB and extra-pulmonary TB based on its spread. TB lymphadenitis is one of the extra-pulmonary TB diseases. Patients with a weakened immune system in systemic lupus erythematosus (SLE) have an increased incidence of TB. Case: Here we present a case report of a 21-year-old female patient with SLE diagnosed with tuberculous lymphadenitis at dr. Zainoel Abidin Hospital, Banda Aceh, Indonesia. The patient complained of a lump in the right neck 4 months ago with a diameter of 4 cm, accompanied by fever, decreased appetite, and weight loss. Other than that, the patient also experiences joint pain, hair loss and sun sensitivity since 12 months ago. Chest radiography showed no abnormalities, and fine-needle aspiration biopsy results confirmed tuberculous lymphadenitis. Antinuclear antibody test was borderline. The patient had been taking steroids and hydroxychloroquine for the past 10 months. Currently, the patient is taking the advanced phase of antituberculosis drugs FDC. After undergoing the intensive phase of antituberculosis drugs, the submandibular lump got smaller to a diameter of 2 cm. Conclusion: TB lymphadenitis is a rare case but can occur in conditions of decreased immunity like SLE. It involves some of the immune disorders caused by the long-term use of immunosuppressive therapy.

Abstract
Mycobacterium tuberculosis complex has an impact on public health and is responsible for over one million deaths per year. Substantial numbers of people infected with M. tuberculosis can develop tuberculosis lymphadenitis; however, there is a limited study in Adama, Ethiopia. The aim of this study was to determine the magnitude of Tuberculosis lymphadenitis, its predictors, and rifampicin-resistance gene-positive M. tuberculosis. A total of 291 patients with enlarged lymph nodes were recruited from May 2022 to August 30 at Adama Comprehensive Specialized Hospital Medical College (ACSHMC). GeneXpert, Ziehl-Neelsen staining, and cytology were used for the diagnosis of TB lymphadenitis from the Fine Needle Aspirate (FNA) specimen. Rifampicin-resistant gene was detected using GeneXpert. For data entry and analysis, Epi Data version 3.0 and SPSS version 25 were used respectively. A binary logistic regression model was used to identify predictors of TB lymphadenitis. A p < 0.05 with a 95% confidence interval (CI) was taken as a cut point to determine the significant association between dependent and independent variables. The prevalence of TB lymphadenitis using GeneXpert, Ziehl-Neelsen staining, and cytology were 138 (47.4%) (95% CI 41.70-53.10), 100 (34.4%) (95% CI 28.94-39.85), and 123 (42.3%) (95% CI 36.63-47.00) respectively. Nine (3.1%) participants were infected with rifampicin-resistant gene-positive M. tuberculosis. Out of the total M. tuberculosis detected by GeneXpert (n = 138), 9 (6.5%) were positive for rifampicin resistance-gene. Participants with a chronic cough had 2 times odds of developing TB lymphadenitis (AOR: 2.001, 95% CI 1.142-3.508). Close to half of patients with enlarged lymph nodes were positive for M. tuberculosis by the GeneXpert method in the study area. Chronic cough was significantly associated with TB lymphadenitis. Rifampicin-resistant gene-positive M. tuberculosis was relatively prevalent among patients with enlarged lymph node in the study area.

Abstract
A 3-year-old male originating from Djibouti presented with a cervical mass evolving for 2 months. Tuberculous lymphadenopathy was suspected based on biopsy results, and he improved quickly on standard antituberculous quadritherapy. Subsequently some features of the mycobacterium that grew in culture were unusual. The isolate was eventually identified as Mycobacterium canettii , a peculiar species of the Mycobacterium tuberculosis complex.

Abstract
To evaluate the diagnostic accuracy of the Capital Bio Mycobacterium real-time polymerase chain reaction assay Capital Bio assay for lymph node (LN) tuberculosis (LNTB), and to further compare the effect of different types of LN specimens on the detection capability of the test. We retrospectively analyzed the medical records of LNTB patients who met the inclusion criteria. The sensitivity, specificity, positive predictive value, negative predictive value, and area under the curve of Capital Bio assay were calculated to evaluate its diagnostic accuracy compared with the final clinical diagnosis as reference standard. Three hundred sixty-four patients were included in the study. The overall sensitivity, specificity, positive predictive value, negative predictive value, and area under the curve of the Capital Bio assay for LNTB were 74.4%, 100.0%, 100.0%, 34.9%, and 0.87, respectively. For the pus specimens, these values for Capital Bio assay were 93.2%, 100.0%, 100.0%, 27.3%, 0.97, respectively. For the core needle biopsy specimens, these values were 65.9%, 100.0%, 100.0%, 33.3%, and 0.83, respectively. For the fine-needle aspiration specimens, these values were 60.0%, 100.0%, 100.0%, 53.9%, and 0.80, respectively. For the tissue, these values were 59.3%, 100.0%, 100.0%, 33.3%, 0.80, respectively. The Capital Bio assay had good effective for the diagnosis of LNTB. Compared to LN fine-needle aspiration and core needle biopsy specimens and tissue specimens, pus specimens were more suitable for molecular testing and had the best diagnostic efficacy.

Abstract
OBJECTIVES To assess the utility of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for presumptive tuberculosis (TB) patients with intrathoracic enlarged lymph nodes in a country with low to moderate TB incidence. METHODS Thirty-one patients with clinical features of TB and intrathoracic lymphadenopathy, who had EBUS-TBNA sampling and final confirmation of intrathoracic TB lymphadenopathy, were retrospectively reviewed over an 8-year period. Routine clinical and laboratory evaluations including computerized tomography scans were performed before the EBUS-TBNA. Sociodemographic characteristics, clinical profile, pathological, and microbiological findings were collected. RESULTS The EBUS-TBNA confirmed TB diagnosis in 26 (83.9%) subjects with a consistent pathological finding or positive culture of Mycobacterium tuberculosis. Pathological analysis had findings consistent with TB in 25 (80.6%) patients. Culture of the EBUS-TBNA sample was positive for Mycobacterium tuberculosis in 12 (38.7%) patients. Other supportive investigations like purified protein derivative (PPD) skin test was positive in 28 (90.3%) participants. Overall, the sensitivity of the EBUS-TBNA alone was 83.9%. No complications were recorded during the procedure. The EBUS-TBNA aspirate culture positivity was significantly related to having a larger size lymph node (p=0.048) only, while PPD positivity was significantly related to baseline and clinical features of the participants. CONCLUSION The EBUS-TBNA demonstrated effective utility and safety in the evaluation and diagnosis of intrathoracic TB lymphadenopathy among individuals with compatible symptoms in a country with low-moderate TB-incidence.

Abstract
BACKGROUND Lymphadenopathy is one of the most prevalent clinical manifestations of extrapulmonary tuberculosis. Endosonography is the recommended technique in the diagnostic work-up of mediastinal lymphadenopathies. Xpert MTB/RIF assay is a self-contained cartridge-based fully automated DNA testing platform which can accurately detect both tuberculosis and mycobacterial resistance to rifampicin. A few studies assessed its accuracy for mediastinal lymph node aspirates collected using endosonography. A systematic review of observational studies was performed to provide a pooled estimate of sensitivity and specificity of Xpert MTB/RIF in the diagnosis of mediastinal tuberculous lymphadenitis using endoscopic ultrasound-guided needle aspiration techniques. METHODS A search of the scientific evidence was carried out using PubMed, Embase, and Scopus. Articles describing observational studies on Xpert MTB/RIF in the diagnosis of mediastinal tuberculous lymphadenitis using endoscopic ultrasound-guided needle aspiration techniques were selected. RESULTS Eight studies met the inclusion criteria. The overall pooled sensitivity was 61% (95% CI = 55-68%; I2 = 66.3%; p = 0.004), overall pooled specificity was 89% (95% CI = 85-91%; I2 = 90.1%; p < 0.0001). Area under the sROC curve was 0.68. Only one study reported data on rifampin resistance detection and showed a sensitivity of 83.3% and a specificity of 16%. CONCLUSIONS Xpert MTB/RIF shows a good accuracy in the diagnosis of mediastinal mycobacterial lymphadenitis by endosonographic needle aspiration techniques. It should be always recommended for suspected mediastinal tuberculosis.

Abstract
BACKGROUND Extra pulmonary tuberculosis (EPTB) constitutes 18% of all tuberculosis (TB) cases and tuberculous lymphadenitis (TBL) constitutes 20-40% of EPTB. Diagnosis of TBL is challenging because of the paucibacillary nature of the disease. OBJECTIVE To investigate the diagnostic potential of a new antigen detection test based on the detection of M. tuberculosis complex specific antigen MPT64 from fine needle aspirate (FNA) cytology smears and biopsies obtained from patients with clinically suspected TBL using immunohistochemistry (IHC). MATERIALS AND METHODS This study was conducted at Khyber Teaching Hospital and Rehman Medical Institute, Peshawar, Pakistan, from January 2018 to April 2019. Samples, including FNA (n = 100) and biopsies (n = 8), were collected from 100 patients with presumptive TBL. Direct smears and cell blocks were prepared from the FNA samples. All samples were subjected to hematoxylin-eosin (H&E) staining, Ziehl-Neelsen (ZN) staining, and immunostaining with polyclonal anti-MPT64 antibody. The culture was performed only for biopsy specimens. All patients were followed until the completion of anti-TB treatment. The response to treatment was included in the composite reference standard (CRS) and used as the gold standard to validate the diagnostic tests. RESULTS The sensitivity, specificity, positive and negative predictive values for ZN staining were 4.4%,100%,100%,56%, for culture were 66%,100%,100%,50%, for cytomorphology were 100%,90.91%,90%,100%, and for immunostaining with anti-MPT64 were all 100%,respectively. The morphology and performance of immunohistochemistry were better with cell blocks than with smears. CONCLUSION MPT64 antigen detection test performed better than ZN and cytomorphology in diagnosing TBL. This test applied to cell blocks from FNA is robust, simple, and relatively rapid, and improves the diagnosis of TBL.

Abstract
INTRODUCTION Mediastinal granulomatous lymphadenopathies, such as tuberculous lymphadenitis, sarcoidosis, are frequently encountered by respiratory physicians, and their diagnosis is based on histological and microbiological tests. Endobronchial ultrasound-guided Trans bronchial needle aspiration (EBUS-TBNA) is widely used to perform mediastinal lymph node sampling. However, very limited data is available on the yield of polymerase chain reaction for Mycobacterium tuberculosis (TB-PCR) using EBUS-TBNA samples in patients with mediastinal granulomatous lymphadenopathy. MATERIALS AND METHODS A retrospective study using a prospectively collected database was performed from January 1, 2018 to December 31, 2018, to evaluate the efficacy of the TB-PCR test using EBUS-TBNA samples in patients with benign mediastinal lymphadenopathy which included both granulomatous lymphadenopathy and reactive lymphadenopathy. The cohort with reactive lymphadenopathy acted as the control group of the study population. The patients with mediastinal lymphadenopathy who were awaiting EBUS-TBNA either for diagnostic evaluation of primary disease or for staging of a known malignancy were included in the study. The patients were then followed up for 1 year post procedure with clinical and radiological evaluation. RESULTS Of the 310 patients with mediastinal lymphadenopathy who underwent EBUS-TBNA, 190 cases had a benign pathology with granulomatous lymphadenopathy in 120 and reactive lymphadenopathy in 70 patients. The sensitivity, specificity, the positive predictive value and the negative predictive value of TB-PCR was at 90%, 97.14%, 98.18%, and 85% respectively. The accuracy of TB-PCR is 92.63%. CONCLUSION TB-PCR using EBUS-TBNA samples is an effective tool for diagnosing mediastinal granulomatous lymphadenopathy. This technique can prevent further invasive interventions like mediastinoscopy in patients whose histological and microbiological tests are non-diagnostic. It should always be performed when tuberculosis is in the differential diagnosis of a patient with mediastinal lymphadenopathy.

Abstract
INTRODUCTION Kikuchi-Fujimoto disease is a benign and self-limiting systemic disorder of unknown aetiology characterised by fever, superficial lymphadenopathy and leukopenia. In highly endemic & low-resource country like India, it is frequently misdiagnosed as tuberculosis. CASE REPORT Both the cases were diagnosed as necrotizing lymphadenitis by fine-needle aspiration cytology. Tuberculin skin prick test (TST) was positive for one case and negative for the other case. Cartridge based nucleic acid amplification test (CBNAAT) from lymph node aspirate was negative for mycobacterium tuberculosis in both the cases, later on histopathology of lymph node showed diagnosis of Kikuchi-Fujimoto disease. CONCLUSION Kikuchi Fujimoto is a self-limiting disease systemic disease of unknown aetiology. A definite diagnosis can be established by incisional/excisional biopsy of the lymph node. When dealing with cases of tubercular lymphadenitis, Kikuchi-Fujimoto disease should be kept as differential diagnosis.

Abstract
BACKGROUND Every year, an estimated one million children and young adolescents become ill with tuberculosis, and around 226,000 of those children die. Xpert MTB/RIF Ultra (Xpert Ultra) is a molecular World Health Organization (WHO)-recommended rapid diagnostic test that simultaneously detects Mycobacterium tuberculosis complex and rifampicin resistance. We previously published a Cochrane Review 'Xpert MTB/RIF and Xpert MTB/RIF Ultra assays for tuberculosis disease and rifampicin resistance in children'. The current review updates evidence on the diagnostic accuracy of Xpert Ultra in children presumed to have tuberculosis disease. Parts of this review update informed the 2022 WHO updated guidance on management of tuberculosis in children and adolescents. OBJECTIVES To assess the diagnostic accuracy of Xpert Ultra for detecting: pulmonary tuberculosis, tuberculous meningitis, lymph node tuberculosis, and rifampicin resistance, in children with presumed tuberculosis. Secondary objectives To investigate potential sources of heterogeneity in accuracy estimates. For detection of tuberculosis, we considered age, comorbidity (HIV, severe pneumonia, and severe malnutrition), and specimen type as potential sources. To summarize the frequency of Xpert Ultra trace results. SEARCH METHODS We searched the Cochrane Infectious Diseases Group Specialized Register, MEDLINE, Embase, three other databases, and three trial registers without language restrictions to 9 March 2021. SELECTION CRITERIA Cross-sectional and cohort studies and randomized trials that evaluated Xpert Ultra in HIV-positive and HIV-negative children under 15 years of age. We included ongoing studies that helped us address the review objectives. We included studies evaluating sputum, gastric, stool, or nasopharyngeal specimens (pulmonary tuberculosis), cerebrospinal fluid (tuberculous meningitis), and fine needle aspirate or surgical biopsy tissue (lymph node tuberculosis). For detecting tuberculosis, reference standards were microbiological (culture) or composite reference standard; for stool, we also included Xpert Ultra performed on a routine respiratory specimen. For detecting rifampicin resistance, reference standards were drug susceptibility testing or MTBDRplus. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and, using QUADAS-2, assessed methodological quality judging risk of bias separately for each target condition and reference standard. For each target condition, we used the bivariate model to estimate summary sensitivity and specificity with 95% confidence intervals (CIs). We stratified all analyses by type of reference standard. We summarized the frequency of Xpert Ultra trace results; trace represents detection of a very low quantity of Mycobacterium tuberculosis DNA. We assessed certainty of evidence using GRADE. MAIN RESULTS We identified 14 studies (11 new studies since the previous review). For detection of pulmonary tuberculosis, 335 data sets (25,937 participants) were available for analysis. We did not identify any studies that evaluated Xpert Ultra accuracy for tuberculous meningitis or lymph node tuberculosis. Three studies evaluated Xpert Ultra for detection of rifampicin resistance. Ten studies (71%) took place in countries with a high tuberculosis burden based on WHO classification. Overall, risk of bias was low. Detection of pulmonary tuberculosis Sputum, 5 studies Xpert Ultra summary sensitivity verified by culture was 75.3% (95% CI 64.3 to 83.8; 127 participants; high-certainty evidence), and specificity was 97.1% (95% CI 94.7 to 98.5; 1054 participants; high-certainty evidence). Gastric aspirate, 7 studies Xpert Ultra summary sensitivity verified by culture was 70.4% (95% CI 53.9 to 82.9; 120 participants; moderate-certainty evidence), and specificity was 94.1% (95% CI 84.8 to 97.8; 870 participants; moderate-certainty evidence). Stool, 6 studies Xpert Ultra summary sensitivity verified by culture was 56.1% (95% CI 39.1 to 71.7; 200 participants; moderate-certainty evidence), and specificity was 98.0% (95% CI 93.3 to 99.4; 1232 participants; high certainty-evidence). Nasopharyngeal aspirate, 4 studies Xpert Ultra summary sensitivity verified by culture was 43.7% (95% CI 26.7 to 62.2; 46 participants; very low-certainty evidence), and specificity was 97.5% (95% CI 93.6 to 99.0; 489 participants; high-certainty evidence). Xpert Ultra sensitivity was lower against a composite than a culture reference standard for all specimen types other than nasopharyngeal aspirate, while specificity was similar against both reference standards. Interpretation of results In theory, for a population of 1000 children: • where 100 have pulmonary tuberculosis in sputum (by culture): - 101 would be Xpert Ultra-positive, and of these, 26 (26%) would not have pulmonary tuberculosis (false positive); and - 899 would be Xpert Ultra-negative, and of these, 25 (3%) would have tuberculosis (false negative). • where 100 have pulmonary tuberculosis in gastric aspirate (by culture): - 123 would be Xpert Ultra-positive, and of these, 53 (43%) would not have pulmonary tuberculosis (false positive); and - 877 would be Xpert Ultra-negative, and of these, 30 (3%) would have tuberculosis (false negative). • where 100 have pulmonary tuberculosis in stool (by culture): - 74 would be Xpert Ultra-positive, and of these, 18 (24%) would not have pulmonary tuberculosis (false positive); and - 926 would be Xpert Ultra-negative, and of these, 44 (5%) would have tuberculosis (false negative). • where 100 have pulmonary tuberculosis in nasopharyngeal aspirate (by culture): - 66 would be Xpert Ultra-positive, and of these, 22 (33%) would not have pulmonary tuberculosis (false positive); and - 934 would be Xpert Ultra-negative, and of these, 56 (6%) would have tuberculosis (false negative). Detection of rifampicin resistance Xpert Ultra sensitivity was 100% (3 studies, 3 participants; very low-certainty evidence), and specificity range was 97% to 100% (3 studies, 128 participants; low-certainty evidence). Trace results Xpert Ultra trace results, regarded as positive in children by WHO standards, were common. Xpert Ultra specificity remained high in children, despite the frequency of trace results. AUTHORS' CONCLUSIONS We found Xpert Ultra sensitivity to vary by specimen type, with sputum having the highest sensitivity, followed by gastric aspirate and stool. Nasopharyngeal aspirate had the lowest sensitivity. Xpert Ultra specificity was high against both microbiological and composite reference standards. However, the evidence base is still limited, and findings may be imprecise and vary by study setting. Although we found Xpert Ultra accurate for detection of rifampicin resistance, results were based on a very small number of studies that included only three children with rifampicin resistance. Therefore, findings should be interpreted with caution. Our findings provide support for the use of Xpert Ultra as an initial rapid molecular diagnostic in children being evaluated for tuberculosis.

Abstract
Peripancreatic tuberculous lymphadenopathy can mimic pancreatic cancer on imaging. There have only a few reports on varices from portal vein obstruction due to abdominal tuberculous lymphadenopathy. Iatrogenic disseminated tuberculosis is also rare. Herein, we present a rare case of peripancreatic tuberculous lymphadenopathy with ruptured duodenal varices due to portal vein obstruction. The patient presented to our hospital with hematemesis. Computed tomography revealed a peripancreatic mass. Duodenal varices rupture from portal vein obstruction due to pancreatic cancer were initially suspected. The patient underwent portal vein stenting for portal vein obstruction and endoscopic ultrasound-guided fine-needle aspiration for diagnosis, which revealed granulomas indicative of tuberculosis. The patient was discharged once because fine-needle aspiration did not lead to a definitive diagnosis of tuberculosis. Subsequently, he developed disseminated tuberculosis. Peripancreatic tuberculous lymphadenopathy can cause ectopic varices with portal vein obstruction. Tuberculosis should also be included in the differential diagnosis in the case of portal vein obstruction, to facilitate early treatment and avoid unnecessary surgery. Furthermore, fine-needle aspiration or portal vein stenting for tuberculous lesions can cause disseminated tuberculosis. Since a diagnosis might not be made until after several fine-needle aspirations have been conducted, careful follow-up is necessary after the procedure for such lesions.

Abstract
BACKGROUND The World Health Organization (WHO) End TB Strategy stresses universal access to drug susceptibility testing (DST). DST determines whether Mycobacterium tuberculosis bacteria are susceptible or resistant to drugs. Xpert MTB/XDR is a rapid nucleic acid amplification test for detection of tuberculosis and drug resistance in one test suitable for use in peripheral and intermediate level laboratories. In specimens where tuberculosis is detected by Xpert MTB/XDR, Xpert MTB/XDR can also detect resistance to isoniazid, fluoroquinolones, ethionamide, and amikacin. OBJECTIVES To assess the diagnostic accuracy of Xpert MTB/XDR for pulmonary tuberculosis in people with presumptive pulmonary tuberculosis (having signs and symptoms suggestive of tuberculosis, including cough, fever, weight loss, night sweats). To assess the diagnostic accuracy of Xpert MTB/XDR for resistance to isoniazid, fluoroquinolones, ethionamide, and amikacin in people with tuberculosis detected by Xpert MTB/XDR, irrespective of rifampicin resistance (whether or not rifampicin resistance status was known) and with known rifampicin resistance. SEARCH METHODS We searched multiple databases to 23 September 2021. We limited searches to 2015 onwards as Xpert MTB/XDR was launched in 2020. SELECTION CRITERIA Diagnostic accuracy studies using sputum in adults with presumptive or confirmed pulmonary tuberculosis. Reference standards were culture (pulmonary tuberculosis detection); phenotypic DST (pDST), genotypic DST (gDST),composite (pDST and gDST) (drug resistance detection). DATA COLLECTION AND ANALYSIS Two review authors independently reviewed reports for eligibility and extracted data using a standardized form. For multicentre studies, we anticipated variability in the type and frequency of mutations associated with resistance to a given drug at the different centres and considered each centre as an independent study cohort for quality assessment and analysis. We assessed methodological quality with QUADAS-2, judging risk of bias separately for each target condition and reference standard. For pulmonary tuberculosis detection, owing to heterogeneity in participant characteristics and observed specificity estimates, we reported a range of sensitivity and specificity estimates and did not perform a meta-analysis. For drug resistance detection, we performed meta-analyses by reference standard using bivariate random-effects models. Using GRADE, we assessed certainty of evidence of Xpert MTB/XDR accuracy for detection of resistance to isoniazid and fluoroquinolones in people irrespective of rifampicin resistance and to ethionamide and amikacin in people with known rifampicin resistance, reflecting real-world situations. We used pDST, except for ethionamide resistance where we considered gDST a better reference standard. MAIN RESULTS We included two multicentre studies from high multidrug-resistant/rifampicin-resistant tuberculosis burden countries, reporting on six independent study cohorts, involving 1228 participants for pulmonary tuberculosis detection and 1141 participants for drug resistance detection. The proportion of participants with rifampicin resistance in the two studies was 47.9% and 80.9%. For tuberculosis detection, we judged high risk of bias for patient selection owing to selective recruitment. For ethionamide resistance detection, we judged high risk of bias for the reference standard, both pDST and gDST, though we considered gDST a better reference standard. Pulmonary tuberculosis detection - Xpert MTB/XDR sensitivity range, 98.3% (96.1 to 99.5) to 98.9% (96.2 to 99.9) and specificity range, 22.5% (14.3 to 32.6) to 100.0% (86.3 to 100.0); median prevalence of pulmonary tuberculosis 91.3%, (interquartile range, 89.3% to 91.8%), (2 studies; 1 study reported on 2 cohorts, 1228 participants; very low-certainty evidence, sensitivity and specificity). Drug resistance detection People irrespective of rifampicin resistance - Isoniazid resistance: Xpert MTB/XDR summary sensitivity and specificity (95% confidence interval (CI)) were 94.2% (87.5 to 97.4) and 98.5% (92.6 to 99.7) against pDST, (6 cohorts, 1083 participants, moderate-certainty evidence, sensitivity and specificity). - Fluoroquinolone resistance: Xpert MTB/XDR summary sensitivity and specificity were 93.2% (88.1 to 96.2) and 98.0% (90.8 to 99.6) against pDST, (6 cohorts, 1021 participants; high-certainty evidence, sensitivity; moderate-certainty evidence, specificity). People with known rifampicin resistance - Ethionamide resistance: Xpert MTB/XDR summary sensitivity and specificity were 98.0% (74.2 to 99.9) and 99.7% (83.5 to 100.0) against gDST, (4 cohorts, 434 participants; very low-certainty evidence, sensitivity and specificity). - Amikacin resistance: Xpert MTB/XDR summary sensitivity and specificity were 86.1% (75.0 to 92.7) and 98.9% (93.0 to 99.8) against pDST, (4 cohorts, 490 participants; low-certainty evidence, sensitivity; high-certainty evidence, specificity). Of 1000 people with pulmonary tuberculosis, detected as tuberculosis by Xpert MTB/XDR: - where 50 have isoniazid resistance, 61 would have an Xpert MTB/XDR result indicating isoniazid resistance: of these, 14/61 (23%) would not have isoniazid resistance (FP); 939 (of 1000 people) would have a result indicating the absence of isoniazid resistance: of these, 3/939 (0%) would have isoniazid resistance (FN). - where 50 have fluoroquinolone resistance, 66 would have an Xpert MTB/XDR result indicating fluoroquinolone resistance: of these, 19/66 (29%) would not have fluoroquinolone resistance (FP); 934 would have a result indicating the absence of fluoroquinolone resistance: of these, 3/934 (0%) would have fluoroquinolone resistance (FN). - where 300 have ethionamide resistance, 296 would have an Xpert MTB/XDR result indicating ethionamide resistance: of these, 2/296 (1%) would not have ethionamide resistance (FP); 704 would have a result indicating the absence of ethionamide resistance: of these, 6/704 (1%) would have ethionamide resistance (FN). - where 135 have amikacin resistance, 126 would have an Xpert MTB/XDR result indicating amikacin resistance: of these, 10/126 (8%) would not have amikacin resistance (FP); 874 would have a result indicating the absence of amikacin resistance: of these, 19/874 (2%) would have amikacin resistance (FN). AUTHORS' CONCLUSIONS Review findings suggest that, in people determined by Xpert MTB/XDR to be tuberculosis-positive, Xpert MTB/XDR provides accurate results for detection of isoniazid and fluoroquinolone resistance and can assist with selection of an optimised treatment regimen. Given that Xpert MTB/XDR targets a limited number of resistance variants in specific genes, the test may perform differently in different settings. Findings in this review should be interpreted with caution. Sensitivity for detection of ethionamide resistance was based only on Xpert MTB/XDR detection of mutations in the inhA promoter region, a known limitation. High risk of bias limits our confidence in Xpert MTB/XDR accuracy for pulmonary tuberculosis. Xpert MTB/XDR's impact will depend on its ability to detect tuberculosis (required for DST), prevalence of resistance to a given drug, health care infrastructure, and access to other tests.

Abstract
Classic Rosai-Dorfman-Destombes disease (RDD) is a rare histiocytic disorder with bilateral massive painless cervical lymphadenopathy. It is a mysterious disease and there is little knowledge of its pathogenesis, clinical features, radiological findings, laboratory investigations, effective treatments and prognosis. Some of its clinical presentations may overlap with those of Mycobacterium tuberculosis infection. Just like tuberculosis infection, RDD may involve many other organs, for example, skin, kidney, bone, brain and spine. The diagnosis can easily be overlooked, especially in communities hyperendemic to tuberculosis infection. We report our experience in diagnosing and managing a patient with spinal RDD with concurrent tuberculosis infection, who was treated empirically for cervical tuberculous lymphadenitis without a conclusive laboratory finding prior to her spinal condition. In view of her acute neurological deficit, emergency spinal decompression was performed. Her intraoperative spinal samples had shown classic histopathological features of RDD. We believe the lymphadenopathy was part of the clinical presentation of RDD. She showed favourable neurological recovery throughout the follow-up.

Abstract
We present a case of a 37-year-old Caucasian woman with abdominal distension and loss of weight. She was initially presumed to be a case of ovarian malignancy due to an elevated serum cancer antigen 125 (CA 125) level and imaging of abdomen and pelvis that showed ascites and bulky ovaries. However, histological examination of biopsy later revealed it to be a case of abdominal tuberculosis (AbT). Ascitic fluid was also found to be positive for Mycobacterium tuberculosis by whole genome sequencing. The patient was started on antituberculosis treatment following which she showed a significant improvement in her symptoms.

Abstract
INTRODUCTION Gastric tuberculosis is rarely seen in clinical practice, which occurs mostly secondary to lung tuberculosis, intestinal tuberculosis, and other common tuberculosis. Gastric tuberculosis rarely presents as a single microscopic superficial erosion. We recently diagnosed such a case, hence reporting it herein. PATIENT CONCERNS A 40-year-old female patient was admitted with a chief complaint of painful enlarged cervical lymph nodes. She had no other symptoms or any previous history of remarkable diseases. DIAGNOSIS Physical examination found multiple enlarged cervical lymph nodes. Computer tomography revealed multiple circular well-defined soft tissue masses in the bilateral carotid sheath spaces. A cervical lymph node biopsy showed caseous necrosis with infiltration of neutrophils and lymphocytes, and most importantly, mycobacteria through staining for acid fast bacilli. Routine gastroscopy showed a 0.5 cm × 0.5 cm well-defined erosion on the large curvature of the gastric body. Gastric biopsy revealed chronic granulomatous inflammation with mycobacteria through staining for acid fast bacilli. The patient was diagnosed as having cervical lymph node tuberculosis and gastric tuberculosis. INTERVENTIONS AND OUTCOMES She received 6 months of standard anti-tuberculosis therapy. The enlarged cervical lymph nodes shrank in size and the pain was relieved. CONCLUSIONS Gastroscopy should be performed to look for gastric tuberculosis if the patient presents primary tuberculosis in other organs/tissues such as cervical lymph nodes. If any small erosion is found, a biopsy is justified for checking the possibility of gastric tuberculosis.

Abstract
Tuberculous lymphadenitis is the most common entity of abdominal tuberculosis, which occurs due to reactivation of a latent focus. Its diagnosis requires a high degree of suspicion, for which it requires endoscopic, radiological, and histopathological studies. In the evaluation of lymphadenopathies, endoscopic ultrasound-guided aspiration puncture plays an important role. We present the case of a 22-year-old male patient who was admitted to the Emergency Department of the Arzobispo Loayza National Hospital due to upper gastrointestinal bleeding secondary to tuberculous mesenteric lymphadenitis that compromised the gastric wall.

Abstract
BACKGROUND Diagnosis of extrapulmonary tuberculosis including tuberculous lymphadenitis (TBLN) is challenging because of its atypical clinical presentation, paucibacillary nature of mycobacteria at the infected sites, variation in sensitivity of a test to specimens collected by different methods and from different infected tissues. METHODS In the present study, suspected individuals for lymph node tuberculosis irrespective of age were enrolled prospectively and specimens were collected aseptically by fine needle aspiration (FNA). After the implementation of exclusion criteria, FNA specimens from a total of 278 cases of suspected TBLN were evaluated for cytomorphology (FNAC), presence of acid-fast bacillus (AFB) in smear microscopy and specific detection of mycobacterial DNA in cartridge-based nucleic acid amplification test (CBNAAT). RESULTS The results showed high prevalence of Type II (59.71%), followed by Type I (34.53%) and Type III (5.75%) pattern in FNAC. Non-type II patterns were significantly high in regions outside of the head and neck region (P = 0.031; OR = 2.125) and had an increasing trend of their occurrences with progression of age. The most affected age group was between 16 and 30 years with female preponderance documented in individuals below 45 years, whereas male preponderance was observed in higher age group patients, majority of whom had infected lymph nodes outside of HAN region (P = 0.063, OR = 1.998). The results also showed high sensitivity of CBNAAT (83.04%) method followed by FNAC (72.17%) with AFB smear exhibiting the disappointing results (sensitivity of 10.86%) compared to the CRS. High percentage of positivity was observed in Type III (AFB:25% vs CBNAAT: 100%) followed by Type II (AFB:10.2 vs CBNAAT: 76.5), while low detection was observed from samples with Type I (AFB:4.2 vs CBNAAT: 50). Interestingly, CBNAAT detection of TB was shown to be unaffected by gender, age and site of infection. CONCLUSION The study suggests a possible contributary role of age and gender for cytomorphological pattern distribution of TBLN at various body parts. Although FNAC detected TB in 77.1% of cases which were identified positive by CBNAAT and/or AFB, it is being solely based on cytomorphology cannot be used alone as a reliable diagnostic method for TBLN detection. Further, the negative results in CBNAAT for FNAC positive cases may not necessarily be non-TB cases and must be evaluated by other diagnostic modalities. We recommend for both cytomorphological investigation and CBNNAT for the fine needle aspirates from suspected TBLN and subsequent treatment to reduce the disease burden.

Abstract
The diagnosis of tuberculous lymphadenitis (TB-LAP) is challenging. We evaluated the role of blood CXC chemokine receptor 3 (CXCR3) ligands in its diagnosis. A total of 65 lymphadenopathy patients were enrolled and lymph node sampling was performed. We also recruited 113 control subjects, consisting of 27 with positive results and 86 with negative results, in the interferon (IFN)-γ release assay (IGRA). In all study subjects, whole-blood samples were collected using the IGRA methodology. After incubation, plasma levels of IFN-γ and two CXCR3 ligands, IFN-inducible T-cell a chemoattractant (I-TAC) and monokine induced by IFN-γ (MIG), were measured using immunoassay. Fifty-three TB-LAP patients were enrolled. TB antigen-stimulated IFN-γ, I-TAC, and MIG levels were all significantly higher in the TB-LAP patients than in the controls and non-TB-LAP patients. The levels of I-TAC and MIG, but not IFN-γ, showed significant differences between the TB-LAP patients and IGRA-positive controls. Area under the receiver operating characteristic curves (AUROCs) of IFN-γ, I-TAC, and MIG were 0.955, 0.958, and 0.959, respectively, for differentiating TB-LAP from control group, and were 0.912, 0.956, and 0.936, respectively, for differentiating TB-LAP from non-TB-LAP. In conclusion, the TB antigen-stimulated MIG and I-TAC could be useful biomarkers in the diagnosis of TB-LAP.

Abstract
Persistent lymphadenopathy with or without fever is often a diagnostic challenge to the physician which are usually caused by infection like tuberculosis, hematological malignancy (lymphoma, leukemia), connective tissue diseases (SLE, RA, Sjogren's syndrome etc.), sarcoidosis, storage diseases, drugs (like phenytoin) in Bangladesh. To establish the cause of lymphadenopathy, we need to do a good number of investigations including invasive tests like FNAC or histopathology of the involved lymph node. In many instances these are not possible due to unavailability or cost. But for last few years the adenosine deaminase is an enzyme involved in purine catabolism and its significance in the diagnosis of tuberculosis has been demonstrated by many studies. In addition to tuberculosis, elevated serum adenosine deaminase has also been found in lymphoma, sarcoidosis and some connective tissue diseases. The study was intended to assess if there are any significant diagnostic difference in the level of elevated adenosine deaminase between tubercular and different types of non tubercular lymphadenopathy. It included 68 patients, equally divided into two groups, tuberculous lymphadenitis and non-tuberculous lymphadenopathy. Epitheloid granuloma with caseation necrosis in biopsy or FNAC was taken as case definition of tuberculous lymphadenitis. Causes of non-tuberculous lymphadenopathy were established on the basis of clinical findings, laboratory investigations and histopathological diagnosis of biopsy or FNAc materials. This cross-sectional observational study was done in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh over a period of one year and participants of 18 years and above of both genders were included as per consecutive sampling technique. Serum ADA concentrations were estimated by enzymatic method. Mean serum ADA concentration was 25.52±7.11 in tuberculous lymphadenitis and in non-tuberculous lymphadenopathy patients it was 27.29±15.91U/L with no significant difference (p=0.480). The non-tuberculous lymphadenopathy group consisted of Hodgkin disease (n=9), non-Hodgkin lymphoma (n=10), sarcoidosis (n=2), reactive lymphadenitis (n=9) and other lymphadenopathy group (n=4) (that consisted one case of each of follicular hyperplasia, adult Still disease, sinus histiocytosis and Castleman's disease). The mean ADA of these groups was 32.77±13.14U/L, 46.40±46.10U/L, 13.94±2.81U/L and 21.75±3.17U/L respectively. Tuberculous lymphadenitis patients had significantly higher serum ADA than persistent reactive lymphadenitis. On the other hand, there were statistically significant elevation of serum ADA in non-Hodgkin lymphoma and sarcoidosis than in tuberculous lymphadenitis.

Abstract
OBJECTIVE The diagnosis of superficial tuberculous lymphadenitis (TBLN) remains difficult due to low detection rate of etiology. To increase the diagnostic value for TBLN, contrast-enhanced ultrasound (CEUS) guided core biopsy was introduced to obtain the specimen followed by Xpert MTB/RIF (Xpert) and other methods testing and to explore the optimum diagnostic pattern for TBLN in China. METHODS A prospective study was performed on patients with suspected superficial TBLN. All patients underwent CEUS-guided core biopsy from which specimens were tested by histopathology, Xpert, acid-fast bacilli (AFB), and MGIT960 culture (MGIT960), respectively. The diagnostic values were calculated and compared. RESULTS A total of 328 patients were included the study, 272 were diagnosed as TBLN (254 definite TB, 18 probable TB) and 56 cases with Non-TBLN, and 100% (272/272) of TBLN patients obtained diagnosis sampled by CEUS-guided core biopsy. The overall sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of comprehensive diagnosis on the specimens by CEUS-guided core biopsy for TBLN were 100% ( 272/272, 95% CI 98.26-100.00), 94.64% (53/56, 95% CI 84.20-98.61), 98.91% (272/275, 95% CI 96.58-99.72), and 100% (53/53, 95% CI 91.58-100%), respectively. Xpert obtained 93.31% (237/254) of etiology detection rate on the specimens sampling by CEUS-guided biopsy. The etiology detection rate was associated with histopathological caseous necrosis. CONCLUSIONS Current examinations on specimens by CEUS-guided core biopsy can achieve a high diagnostic efficacy for TBLN. Pathological differentiation of CEUS-guided biopsy tissue, then followed by Xpert, may be the best pattern for the diagnosis of TBLN in high TB burden areas.

Abstract
BACKGROUND Xpert MTB/RIF Ultra (Xpert Ultra) and Xpert MTB/RIF are World Health Organization (WHO)-recommended rapid nucleic acid amplification tests (NAATs) widely used for simultaneous detection of Mycobacterium tuberculosis complex and rifampicin resistance in sputum. To extend our previous review on extrapulmonary tuberculosis (Kohli 2018), we performed this update to inform updated WHO policy (WHO Consolidated Guidelines (Module 3) 2020). OBJECTIVES To estimate diagnostic accuracy of Xpert Ultra and Xpert MTB/RIF for extrapulmonary tuberculosis and rifampicin resistance in adults with presumptive extrapulmonary tuberculosis. SEARCH METHODS Cochrane Infectious Diseases Group Specialized Register, MEDLINE, Embase, Science Citation Index, Web of Science, Latin American Caribbean Health Sciences Literature, Scopus, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform, the International Standard Randomized Controlled Trial Number Registry, and ProQuest, 2 August 2019 and 28 January 2020 (Xpert Ultra studies), without language restriction. SELECTION CRITERIA Cross-sectional and cohort studies using non-respiratory specimens. Forms of extrapulmonary tuberculosis: tuberculous meningitis and pleural, lymph node, bone or joint, genitourinary, peritoneal, pericardial, disseminated tuberculosis. Reference standards were culture and a study-defined composite reference standard (tuberculosis detection); phenotypic drug susceptibility testing and line probe assays (rifampicin resistance detection). DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed risk of bias and applicability using QUADAS-2. For tuberculosis detection, we performed separate analyses by specimen type and reference standard using the bivariate model to estimate pooled sensitivity and specificity with 95% credible intervals (CrIs). We applied a latent class meta-analysis model to three forms of extrapulmonary tuberculosis. We assessed certainty of evidence using GRADE. MAIN RESULTS 69 studies: 67 evaluated Xpert MTB/RIF and 11 evaluated Xpert Ultra, of which nine evaluated both tests. Most studies were conducted in China, India, South Africa, and Uganda. Overall, risk of bias was low for patient selection, index test, and flow and timing domains, and low (49%) or unclear (43%) for the reference standard domain. Applicability for the patient selection domain was unclear for most studies because we were unsure of the clinical settings. Cerebrospinal fluid Xpert Ultra (6 studies) Xpert Ultra pooled sensitivity and specificity (95% CrI) against culture were 89.4% (79.1 to 95.6) (89 participants; low-certainty evidence) and 91.2% (83.2 to 95.7) (386 participants; moderate-certainty evidence). Of 1000 people where 100 have tuberculous meningitis, 168 would be Xpert Ultra-positive: of these, 79 (47%) would not have tuberculosis (false-positives) and 832 would be Xpert Ultra-negative: of these, 11 (1%) would have tuberculosis (false-negatives). Xpert MTB/RIF (30 studies) Xpert MTB/RIF pooled sensitivity and specificity against culture were 71.1% (62.8 to 79.1) (571 participants; moderate-certainty evidence) and 96.9% (95.4 to 98.0) (2824 participants; high-certainty evidence). Of 1000 people where 100 have tuberculous meningitis, 99 would be Xpert MTB/RIF-positive: of these, 28 (28%) would not have tuberculosis; and 901 would be Xpert MTB/RIF-negative: of these, 29 (3%) would have tuberculosis. Pleural fluid Xpert Ultra (4 studies) Xpert Ultra pooled sensitivity and specificity against culture were 75.0% (58.0 to 86.4) (158 participants; very low-certainty evidence) and 87.0% (63.1 to 97.9) (240 participants; very low-certainty evidence). Of 1000 people where 100 have pleural tuberculosis, 192 would be Xpert Ultra-positive: of these, 117 (61%) would not have tuberculosis; and 808 would be Xpert Ultra-negative: of these, 25 (3%) would have tuberculosis. Xpert MTB/RIF (25 studies) Xpert MTB/RIF pooled sensitivity and specificity against culture were 49.5% (39.8 to 59.9) (644 participants; low-certainty evidence) and 98.9% (97.6 to 99.7) (2421 participants; high-certainty evidence). Of 1000 people where 100 have pleural tuberculosis, 60 would be Xpert MTB/RIF-positive: of these, 10 (17%) would not have tuberculosis; and 940 would be Xpert MTB/RIF-negative: of these, 50 (5%) would have tuberculosis. Lymph node aspirate Xpert Ultra (1 study) Xpert Ultra sensitivity and specificity (95% confidence interval) against composite reference standard were 70% (51 to 85) (30 participants; very low-certainty evidence) and 100% (92 to 100) (43 participants; low-certainty evidence). Of 1000 people where 100 have lymph node tuberculosis, 70 would be Xpert Ultra-positive and 0 (0%) would not have tuberculosis; 930 would be Xpert Ultra-negative and 30 (3%) would have tuberculosis. Xpert MTB/RIF (4 studies) Xpert MTB/RIF pooled sensitivity and specificity against composite reference standard were 81.6% (61.9 to 93.3) (377 participants; low-certainty evidence) and 96.4% (91.3 to 98.6) (302 participants; low-certainty evidence). Of 1000 people where 100 have lymph node tuberculosis, 118 would be Xpert MTB/RIF-positive and 37 (31%) would not have tuberculosis; 882 would be Xpert MTB/RIF-negative and 19 (2%) would have tuberculosis. In lymph node aspirate, Xpert MTB/RIF pooled specificity against culture was 86.2% (78.0 to 92.3), lower than that against a composite reference standard. Using the latent class model, Xpert MTB/RIF pooled specificity was 99.5% (99.1 to 99.7), similar to that observed with a composite reference standard. Rifampicin resistance Xpert Ultra (4 studies) Xpert Ultra pooled sensitivity and specificity were 100.0% (95.1 to 100.0), (24 participants; low-certainty evidence) and 100.0% (99.0 to 100.0) (105 participants; moderate-certainty evidence). Of 1000 people where 100 have rifampicin resistance, 100 would be Xpert Ultra-positive (resistant): of these, zero (0%) would not have rifampicin resistance; and 900 would be Xpert Ultra-negative (susceptible): of these, zero (0%) would have rifampicin resistance. Xpert MTB/RIF (19 studies) Xpert MTB/RIF pooled sensitivity and specificity were 96.5% (91.9 to 98.8) (148 participants; high-certainty evidence) and 99.1% (98.0 to 99.7) (822 participants; high-certainty evidence). Of 1000 people where 100 have rifampicin resistance, 105 would be Xpert MTB/RIF-positive (resistant): of these, 8 (8%) would not have rifampicin resistance; and 895 would be Xpert MTB/RIF-negative (susceptible): of these, 3 (0.3%) would have rifampicin resistance. AUTHORS' CONCLUSIONS Xpert Ultra and Xpert MTB/RIF may be helpful in diagnosing extrapulmonary tuberculosis. Sensitivity varies across different extrapulmonary specimens: while for most specimens specificity is high, the tests rarely yield a positive result for people without tuberculosis. For tuberculous meningitis, Xpert Ultra had higher sensitivity and lower specificity than Xpert MTB/RIF against culture. Xpert Ultra and Xpert MTB/RIF had similar sensitivity and specificity for rifampicin resistance. Future research should acknowledge the concern associated with culture as a reference standard in paucibacillary specimens and consider ways to address this limitation.

Abstract
Acute parotitis progressing to parotid abscess is rare in children. Staphylococcus aureus is the usual pathogen in parotid abscess. Granulomatous parotid abscess due to tubercular aetiology is extremely rare. Authors report a case of chronic parotid abscess in a child who received multiple courses of antibiotics without any cure. The ultrasonography and CT scan of the parotid gland confirmed the extent of parotid abscess and the changes in the parotid lymph nodes. The surgical drainage and the biopsy of the lymph nodes lead to the diagnosis of granulomatous abscess. The antitubercular therapy finally cured the disease without further recurrence.

Abstract
OBJECTIVES This study described the population structure of M. tuberculosis complex (MTBc) strains among patients with pulmonary or lymph node tuberculosis (TB) in Northwest Ethiopia and tested the performance of culture isolation and MPT64-based speciation for Lineage 7 (L7). METHODS Patients were recruited between April 2017 and June 2019 in North Gondar, Ethiopia. The MPT64 assay was used to confirm MTBc, and spoligotyping was used to characterize mycobacterial lineages. Line probe assay (LPA) was used to detect resistance to rifampicin and isoniazid. RESULTS Among 274 MTBc genotyped isolates, there were five MTBc lineages: L1-L4 and L7 were identified, with predominant East-African-Indian (L3) (53.6%) and Euro-American (L4) (40.1%) strains, and low prevalence (2.6%) of Ethiopia L7. The genotypes were similarly distributed between pulmonary and lymph node TB, and all lineages were equally isolated by culture and recognized as MTBc by the MPT64 assay. Additionally, LPA showed that 259 (94.5%) MTBc were susceptible to both rifampicin and isoniazid, and one (0.4%) was multi-drug resistant (resistant to both rifampicin and isoniazid). CONCLUSION These findings show that TB in North Gondar, Ethiopia, is mainly caused by L3 and L4 strains, with low rates of L7, confirmed as MTBc by MPT64 assay and with limited resistance to rifampicin and isoniazid.

Abstract
Kikuchi-Fujimoto disease, also called necrotising histiocytic lymphadenitis, is a rare disease of usually benign outcome. A case of a 21-year female is reported here. She presented with high grade fever and cervical lymphadenopathy. She was started on anti-tubercular treatment (ATT) with suspicion of tuberculous lymphadenitis as she had very strong history of tubercular (TB) contact. Kikuchi-Fujimoto disease was diagnosed after cervical lymph node biopsy, thus ATT was stopped. She was treated with oral steroids and complete recovery was made. Of significant note, two of patient's siblings were treated for pulmonary TB, because of which she had strong history of direct TB contact. Although a few cases of Kikuchi-Fujimoto disease have been reported in Pakistan, this is first case being reported in setting of very strong positive history of TB contact. Key Words: Lymphadenitis, Tuberculosis, Kikuchi-Fujimoto disease.

Abstract
BACKGROUND Every year, at least one million children become ill with tuberculosis and around 200,000 children die. Xpert MTB/RIF and Xpert Ultra are World Health Organization (WHO)-recommended rapid molecular tests that simultaneously detect tuberculosis and rifampicin resistance in adults and children with signs and symptoms of tuberculosis, at lower health system levels. To inform updated WHO guidelines on molecular assays, we performed a systematic review on the diagnostic accuracy of these tests in children presumed to have active tuberculosis. OBJECTIVES Primary objectives • To determine the diagnostic accuracy of Xpert MTB/RIF and Xpert Ultra for (a) pulmonary tuberculosis in children presumed to have tuberculosis; (b) tuberculous meningitis in children presumed to have tuberculosis; (c) lymph node tuberculosis in children presumed to have tuberculosis; and (d) rifampicin resistance in children presumed to have tuberculosis - For tuberculosis detection, index tests were used as the initial test, replacing standard practice (i.e. smear microscopy or culture) - For detection of rifampicin resistance, index tests replaced culture-based drug susceptibility testing as the initial test Secondary objectives • To compare the accuracy of Xpert MTB/RIF and Xpert Ultra for each of the four target conditions • To investigate potential sources of heterogeneity in accuracy estimates - For tuberculosis detection, we considered age, disease severity, smear-test status, HIV status, clinical setting, specimen type, high tuberculosis burden, and high tuberculosis/HIV burden - For detection of rifampicin resistance, we considered multi-drug-resistant tuberculosis burden • To compare multiple Xpert MTB/RIF or Xpert Ultra results (repeated testing) with the initial Xpert MTB/RIF or Xpert Ultra result SEARCH METHODS: We searched the Cochrane Infectious Diseases Group Specialized Register, MEDLINE, Embase, Science Citation Index, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, the WHO International Clinical Trials Registry Platform, ClinicalTrials.gov, and the International Standard Randomized Controlled Trials Number (ISRCTN) Registry up to 29 April 2019, without language restrictions. SELECTION CRITERIA Randomized trials, cross-sectional trials, and cohort studies evaluating Xpert MTB/RIF or Xpert Ultra in HIV-positive and HIV-negative children younger than 15 years. Reference standards comprised culture or a composite reference standard for tuberculosis and drug susceptibility testing or MTBDRplus (molecular assay for detection of Mycobacterium tuberculosis and drug resistance) for rifampicin resistance. We included studies evaluating sputum, gastric aspirate, stool, nasopharyngeal or bronchial lavage specimens (pulmonary tuberculosis), cerebrospinal fluid (tuberculous meningitis), fine needle aspirates, or surgical biopsy tissue (lymph node tuberculosis). DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed study quality using the Quality Assessment of Studies of Diagnostic Accuracy - Revised (QUADAS-2). For each target condition, we used the bivariate model to estimate pooled sensitivity and specificity with 95% confidence intervals (CIs). We stratified all analyses by type of reference standard. We assessed certainty of evidence using the GRADE approach. MAIN RESULTS For pulmonary tuberculosis, 299 data sets (68,544 participants) were available for analysis; for tuberculous meningitis, 10 data sets (423 participants) were available; for lymph node tuberculosis, 10 data sets (318 participants) were available; and for rifampicin resistance, 14 data sets (326 participants) were available. Thirty-nine studies (80%) took place in countries with high tuberculosis burden. Risk of bias was low except for the reference standard domain, for which risk of bias was unclear because many studies collected only one specimen for culture. Detection of pulmonary tuberculosis For sputum specimens, Xpert MTB/RIF pooled sensitivity (95% CI) and specificity (95% CI) verified by culture were 64.6% (55.3% to 72.9%) (23 studies, 493 participants; moderate-certainty evidence) and 99.0% (98.1% to 99.5%) (23 studies, 6119 participants; moderate-certainty evidence). For other specimen types (nasopharyngeal aspirate, 4 studies; gastric aspirate, 14 studies; stool, 11 studies), Xpert MTB/RIF pooled sensitivity ranged between 45.7% and 73.0%, and pooled specificity ranged between 98.1% and 99.6%. For sputum specimens, Xpert Ultra pooled sensitivity (95% CI) and specificity (95% CI) verified by culture were 72.8% (64.7% to 79.6%) (3 studies, 136 participants; low-certainty evidence) and 97.5% (95.8% to 98.5%) (3 studies, 551 participants; high-certainty evidence). For nasopharyngeal specimens, Xpert Ultra sensitivity (95% CI) and specificity (95% CI) were 45.7% (28.9% to 63.3%) and 97.5% (93.7% to 99.3%) (1 study, 195 participants). For all specimen types, Xpert MTB/RIF and Xpert Ultra sensitivity were lower against a composite reference standard than against culture. Detection of tuberculous meningitis For cerebrospinal fluid, Xpert MTB/RIF pooled sensitivity and specificity, verified by culture, were 54.0% (95% CI 27.8% to 78.2%) (6 studies, 28 participants; very low-certainty evidence) and 93.8% (95% CI 84.5% to 97.6%) (6 studies, 213 participants; low-certainty evidence). Detection of lymph node tuberculosis For lymph node aspirates or biopsies, Xpert MTB/RIF pooled sensitivity and specificity, verified by culture, were 90.4% (95% CI 55.7% to 98.6%) (6 studies, 68 participants; very low-certainty evidence) and 89.8% (95% CI 71.5% to 96.8%) (6 studies, 142 participants; low-certainty evidence). Detection of rifampicin resistance Xpert MTB/RIF pooled sensitivity and specificity were 90.0% (67.6% to 97.5%) (6 studies, 20 participants; low-certainty evidence) and 98.3% (87.7% to 99.8%) (6 studies, 203 participants; moderate-certainty evidence). AUTHORS' CONCLUSIONS We found Xpert MTB/RIF sensitivity to vary by specimen type, with gastric aspirate specimens having the highest sensitivity followed by sputum and stool, and nasopharyngeal specimens the lowest; specificity in all specimens was > 98%. Compared with Xpert MTB/RIF, Xpert Ultra sensitivity in sputum was higher and specificity slightly lower. Xpert MTB/RIF was accurate for detection of rifampicin resistance. Xpert MTB/RIF was sensitive for diagnosing lymph node tuberculosis. For children with presumed tuberculous meningitis, treatment decisions should be based on the entirety of clinical information and treatment should not be withheld based solely on an Xpert MTB/RIF result. The small numbers of studies and participants, particularly for Xpert Ultra, limits our confidence in the precision of these estimates.

Abstract
BACKGROUND The spectrum of morphological pattern in tubercular lymphandenopathies was observed to study the various cytomorphological patterns and their correlation with acid fast bacilli. METHODS FNAC smears of 210 cases of granulomatous lymphadenitis stained with Giemsa, Pap and haematoxylin and eosin were used to analyze cytomorphological pattern and Zeihl Neelsen stained smears for acid fast bacilli (AFB) detection. RESULTS 193 cases with necrotising granulomatous inflammation or positive acid fast bacilli were included. Age group 21-30 years was most common (38.3%) followed by age group 11-20 years (30.05%). Females constituted 66.3% of patients and 33.7% were male. Overall the most common pattern in present study was pattern A (Epitheloid granuloma with caseous necrosis 33.7% followed by pattern B (caseous necrosis with few scattered epitheloid histiocytes and lymphocytes) 31.1% and pattern C (caseous necrosis with suppurative inflammation) 30.6%, followed by pattern D (Caseous necrosis only) (3.6%) and pattern E (non necrotising epitheloid granuloma with positive acid fast bacilli) (1.03%). Acid fast bacilli were demonstrable in 175 cases (90.7%). Amongst the acid fast bacilli positive cases highest bacillary load 3+ grade was seen in pattern C in 6/59 (10.16%) cases. CONCLUSION FNAC is a simple useful tool and should be attempted in all cases of lymphandenopathies. It helps in establishing a diagnosis of tubercular etiology based on its morphological patterns however demonstration of acid fast bacilli on aspirated material confirms the diagnosis.

Abstract
BACKGROUND Tuberculous lymphadenitis (TBLA) is the most common extrapulmonary manifestation of tuberculosis (TB) in Denmark. However, the clinical features of patients with TBLA have never been systematically studied in this setting. METHODS Patients treated for TBLA in Central Region Denmark from 2007 to 2016 were identified using the national TB surveillance register and The Danish Hospital Patient Registry. Data of clinical characteristics and treatment were extracted from hospital records. RESULTS Eighty-three TBLA patients were identified. The median age was 32 years (IQR 23-42); 71 (85.5%) were migrants; 58 (69.9%) presented with cervical lymphadenopathy; and 45 (54.2%) had one or more systemic TB symptom such as fever, chills, night sweats, fatigue, and weight loss. Sixty-five patients had no comorbidities (78.3%). HIV co-infection was seen in five (7.2%) of the 69 who were tested for HIV. Abscesses and/or draining sinuses were noted in 13 (15.7%) patients and 15 (18.1%) had concurrent pulmonary infection. The median time from first hospital contact to treatment initiation was 42 days (IQR 16-82) and admitted patients were hospitalised for a median of 7 days (IQR 3-13.5). For 24 patients (28.9%), lymph node material was not sent for mycobacterial culture and 52 (62.7%) had microbiologically confirmed TB. Treatment outcome was successful for 70 patients (84.3%). CONCLUSION In Denmark, TBLA is mainly seen among young and previously healthy migrants presenting with cervical lymphadenopathy and sparse systemic symptoms. The diagnosis is often considerably delayed and not microbiologically verified, implying diagnostic difficulties. Treatment outcome needs to be improved.

Abstract
Cold abscess is an abscess without local pain and warmth and it usually accompanies Tuberculosis. The site varied depending upon the organ affected and cervical region is the commonly affected one. Cyto-morphology of cold abscess usually showed caseation type of necrosis, lymphocytes and granuloma with degenerated epithelioid cells. Here we presented an inguinal cold abscess in 9 years old girl with unique cyto-morphology of plenty of neutrophils, foam cells and lymphocytes in fine needle aspiration smear without caseation necrosis and epithelioid cells. Presence of Mycobacterium in the aspirated pus was proved by Ziehl-Neelsen as well as Auramine fluorescent staining. This characteristic cyto-morphology of mycobacterium infection mimicking pyogenic abscess emphasizes the importance of Ziehl-Neelsen staining in all abscess for early specific diagnosis and effective treatment.

Abstract
Sri Lanka is a tuberculosis (TB) prevalent country with an incidence of 8886 cases in 2016 of which 30% were extra pulmonary tuberculosis (EPTB). These figures may be an underestimation, considering the diagnostic challenge of EPTB due to its diverse presentations and difficulty in microbiological confirmation. Here we describe a case of EPTB which was first diagnosed as granulomatosis with polyangitis when he presented with fever, anorexia, wasting, large joint pains, cervical pain, erythema nodosum, high inflammatory markers with strongly positive Mantoux reaction and, necrotizing granulomatous lymphadenitis in the cervical region. Immunosuppression with methotrexate 15 mg weekly and prednisolone 30 mg daily, achieved resolution of symptoms and the inflammatory markers. After about 4 months on tailing off prednisolone, he developed fever, anorexia, wasting and worsening occipital pain which evolved in to occipital condylar syndrome causing hypoglossal nerve palsy. With the aid of serial radiological, histopathological and bacteriological investigations, he was eventually diagnosed to have EPTB involving the left base of the skull with upper mediastinal lymphadenitis. This case highlights the importance to have a high index of suspicion to diagnose EPTB, especially in a country with a high prevalence of TB and to revise the diagnosis with a close follow up to avoid disastrous consequences associated with misdiagnosis.

Abstract
A 58-year-old man with Crohn's disease received adalimumab for 13 months after screening results for tuberculosis were found to be negative. He was diagnosed with de novo mediastinal lymph-node tuberculosis, which was proved to be bacteriologically identical to that of an individual with smear positive lung tuberculosis by a variable number of tandem repeat analyses. After initiating anti-tuberculosis therapy, the patient developed immune reconstitution syndrome, which was improved by the re-administration of adalimumab. Even in countries with an intermediate tuberculosis burden, including Japan, we need to be alert for de novo tuberculosis as well as its reactivation during tumor necrosis factor-α inhibitor therapy.

Abstract
RATIONALE Rare cases of reactive arthritis induced by active extra-articular tuberculosis (Poncet disease) have been reported. Complete response to antitubercular treatment and evidence of active extra-articular tuberculosis are the most important clinical features of Poncet disease. We report the case of successfully treated a patient with reactive arthritis induced by active extra-articular tuberculosis with a TNF inhibitor after sufficient antitubercular treatment. PATIENT CONCERNS A 56-year-old Japanese man was admitted to our department with polyarthralgia, low back pain, and high fever. The results of rheumatoid factor, anti-citrullinated protein antibody, human leukocyte antigen B27, and the assays for the detection of infections (with an exception of T-SPOT.TB) were all negative. Fluoro-deoxy-D-glucose-positron emission tomography with CT (PET/CT) showed moderate uptake in the right cervical, right supraclavicular, mediastinal, and abdominal lymph nodes. As magnetic resonance imaging and power Doppler ultrasonography showed peripheral inflammation (tendinitis, tenosynovitis, ligamentitis, and enthesitis in the limbs). DIAGNOSIS A diagnosis of tuberculous lymphadenitis was eventually established on the basis of lymph node biopsy results. There was no evidence of a bacterial infection including acid-fast bacteria in his joints, and the symptoms of polyarthralgia and low back pain were improved but not completely resolved with NSAID therapy; in addition, a diagnosis of reactive arthritis induced by active extraarticular tuberculosis was made. INTERVENTIONS The patient experienced persistent peripheral inflammation despite antitubercular treatment for more than nine months and was then successfully treated with a tumor necrosis factor inhibitor (adalimumab 40 mg every 2 weeks). OUTCOMES Finally, the patient responded to the treatment and has been in remission for over 4 months as of this writing. LESSONS In patients who present with symptoms associated with spondyloarthritis, it is important to distinguish between classic reactive arthritis and reactive arthritis induced by extra-articular tuberculosis infection. Introduction of biological agents should be carefully considered in settings where reactive arthritis induced by active extra-articular tuberculosis shows progression to chronicity despite sufficient antitubercular treatment.

Abstract
BACKGROUND The role of Cartridge based Nucleic Acid Amplification test (CBNAAT) in the diagnosis of lymphnode TB which helps in reducing the mortality and morbidity by early identification and initiating treatment at the earliest. Also helps in identify the drug resistance among tubercular lymphnodes cases. PATIENTS AND METHODS A prospective clinical study was performed in 101 suspected lymph node tuberculosis patients. The results of FNAC and/or excision biopsy of lymphnode samples obtained by CBNAAT were compared with direct smear microscopy for AFB bacilli, cytology and their combination considering AFB culture as gold standard. RESULTS A total of 101 patients were evaluated of which 74 subjects (73.3%) were CBNAAT positive for TB. Among the CBNAAT positive cases, 57 were aged above 16 years, 38 were females, equal number (37) had single and multiple lymphnodes, 46 had less than 1cm size lymphnodes, 69 had lymphnode in neck region, 65 had chest X-ray normal. Among CBNAAT positive 74 subjects, 53 subjects (71.6%) were positive for AFB direct smear, 64 subjects (86.48%) were cytology consistent with TB and their combination were positive for TB in 71 subjects (95.94%) and 71 subjects (95.94%) were positive by AFB culture and 3 cases (0.04%) showed Rifampicin resistance. CONCLUSION CBNAAT is a rapid diagnostic tool having sensitivity of 93.42% with specificity of 86.96% and positive predictive value of 95.95% and having comparable results with AFB culture and more sensitive than other investigation procedures. Thus it can be a rule in test for lymphnode TB.

Abstract
INTRODUCTION Tuberculosis (TB) is an infectious and curable disease caused by Mycobacterium tuberculosis complex; it affects both men and women at any age. OBJECTIVE To characterize cases of TB presented at the Michoacán Local Office of IMSS (Mexican Institute of Social Security), from 2015 to 2018. MATERIAL AND METHODS Cross-sectional, observational and analytical study. Cases with a clinical file with complete information and registered in the Epidemiological Surveillance Information System, from 2015 to 2018, at the Michoacán Local Office were included. Descriptive statistics, frequency and association measures were obtained by using XMH and chi squared. RESULTS 328 cases of TB were found, 56% were male; the most affected age group was the one of 65 years and above with 20%; 28% were housewives; 32% had primary education; 30% were from Lazaro Cardenas jurisdiction; 70% presented pulmonary TB; 88% got cured; 25% were associated with diabetes. The association of pulmonary TB with some risk factors was 1.24 times greater in retired: XMH = 2.02, OR = 2.74, chi squared: p = 0.03 (95% CI, 1.03 7.30); 1.15 times greater in males: XMH = 1.97, OR = 1.61, chi-squared: p = 0.04 (95% CI, 1.00 2.60), and 1.21 times greater in the age group of 65 years and above: XMH = 2.34, OR = 2. 21, chi-squared: p = 0.01 (95% CI: 1.12 4.35). CONCLUSION The results of this study are a starting point to prevent, diagnose, control and follow up TB cases at the local office level at IMSS.

Abstract
INTRODUCTION Tuberculous lymphadenitis is the most frequent form of extra-pulmonary TB (EPTB) and accounts for a considerable proportion of all EPTB cases. We conducted a systematic review of articles that described the epidemiological features of TBLN in Africa. METHODS Any article that characterized TBLN cases with respect to demographic, exposure and clinical features were included. Article search was restricted to African countries and those published in English language irrespective of publication year. The articles were retrieved from the electronic database of PubMed, Scopus, Cochrane library and Lens.org. Random effect pooled prevalence with 95% CI was computed based on Dersimonian and Laird method. To stabilize the variance, Freeman-Tukey double arcsine root transformation was done. The data were analyzed using Stata 14. RESULTS Of the total 833 articles retrieved, twenty-eight articles from 12 African countries fulfilled the eligibility criteria. A total of 6746 TBLN cases were identified. The majority of the cases, 4762 (70.6%) were from Ethiopia. Over 77% and 88% of identified TBLN were cervical in type and naïve to TB drugs. Among the total number of TBLN cases, 53% were female, 68% were in the age range of 15-44 years, 52% had a history of livestock exposure, 46% had a history of consuming raw milk/meat and 24% had history of BCG vaccination. The proportion of TBLN/HIV co-infection was much lower in Ethiopia (21%) than in other African countries (73%) and the overall African estimate (52%). Fever was recorded in 45%, night sweating in 55%, weight loss in 62% and cough for longer than two weeks in 32% of the TBLN cases. CONCLUSIONS TBLN was more common in females than in males. The high prevalence of TBLN in Ethiopia did not show directional correlation with HIV. Population based prospective studies are warranted to better define the risk factors of TBLN in Africa.

Abstract
BACKGROUND Tuberculosis is a global public health problem, especially in emerging countries. Mycobacterium tuberculosis is the main cause of cervical lymphadenopathy; nontuberculous mycobacteria are relatively common in children and rare in adults. OBJECTIVE To identify and establish the frequency of infectious etiology by nontuberculous mycobacteria in Mexican adult patients with cervical lymphadenopathy. METHODS The study included 85 patients over 18 years with cervical lymphadenopathy; 45 were HIV-positive, 40 were HIV-negative; they had no history of tuberculosis treatment and were selected from a third-level hospital. It was carried out a biopsy of the lymph node for the histopathological study, a search for acid-fast bacilli, a tube culture to indicate growth of Mycobacterium BACTEC (MGIT-960) and identification of mycobacterial strain by PCR-RFLP (restriction fragment length polymorfism) of hsp65. RESULTS In 42 HIV-positive patients (93%), strains corresponded to Mycobacterium tuberculosis complex, two (4.4%) to M. intracellulare and one (2.2%) to M. gordonae. Among HIV-negative patients, 39 of strains (97.5%) corresponded to patients with M. tuberculosis complex and one strain (2.5%) to M. fortuitum. CONCLUSION The presence of nontuberculous mycobacteria was found in 4.7% of all cases. Despite this low frequency, it must be taken into account as a possible cause of lymphadenopathy, since its prompt identification enables introducing specific treatment.

Abstract
RATIONAL Granulomatous polyangiitis (GPA) is a type of vasculitis involving medium and small arteries, typically affecting the upper and lower respiratory tract with coexisting glomerulonephritis. GPA is also characterized by necrotizing granulomatous inflammation and the presence of antineutrophil cytoplasm antibodies (ANCA). So far, various infections have lead to elevation of titers of serum ANCA, making it difficult to diagnose. PATIENT CONCERNS We report a 50-year-old woman who was diagnosed as tuberculous lymphadenitis. During the treatment by anti-tuberculosis (TB) drugs, rapidly progressive renal failure and pleurisy had appeared with elevated titer of PR3-ANCA. Renal biopsy revealed crescentic glomerulonephritis. DIAGNOSIS Renal biopsy revealed crescentic glomerulonephritis and diagnosis of GPA was made. INTERVENTIONS Steroid therapy had been started with continuation of anti-TB drugs. OUTCOMES Renal dysfunction had gradually recovered and pleurisy had disappeared with decreasing titer of PR3-ANCA. LESSONS This is the first report of GPA complicated by TB infection. When we encounter a case with rapidly progressive renal failure during the TB infection, complication of GPA should be suspected as 1 of the different diagnosis.
