The WHO estimates around a million children contract tuberculosis (TB) annually with over 80 000 deaths from dissemination of infection outside of the lungs. The insidious onset and association with skin test anergy suggests failure of the immune system to both recognise and respond to infection. To understand the immune mechanisms, we studied genome-wide whole blood RNA expression in children with TB meningitis (TBM). Findings were validated in a second cohort of children with TBM and pulmonary TB (PTB), and functional T-cell responses studied in a third cohort of children with TBM, other extrapulmonary TB (EPTB) and PTB...

Endobronchial Ultrasound (EBUS) with the two modalities curved and radial EBUS significantly improved the diagnostics in several pulmonary diseases. The examination and staging of mediastinal and hilar lymph nodes in patients with known or suspected lung malignancy as well as the evaluation of unknown pulmonary or mediastinal lesions can be achieved with minimal invasive means when using EBUS. More invasive surgical procedures for diagnostic purposes can be omitted. The diagnostic yield also increases when EBUS is applied in sarcoidosis or mediastinal lymph node tuberculosis but only to some extend in case of lymphoma...

The endobronchial localization of Hodgkin's disease is a rare entity which is often confused with endobronchial tuberculosis in our setting. We report the case of a 16 years old female who presented with 6 months history of dry cough, hemoptysis, dyspnea, dysphagia and dysphonia. The chest radiography showed a mediastinal and pulmonary opacity. The chest CT scan found enlarged mediastinal lymph nodes. The bronchial biopsy and peripheral lymph node biopsy confirmed Hodgkin's disease with endobronchial localization...

AIMS: Making a correct and rapid diagnosis is essential for managing pulmonary tuberculosis (PTB), particularly multidrug-resistant tuberculosis. We aimed to evaluate the efficacy of the combination of simultaneous amplification testing (SAT) and reverse dot blot (RDB) for the rapid detection of Mycobacterium tuberculosis (MTB) and drug-resistant mutants in respiratory samples. METHODS: 225 suspected PTB and 32 non-TB pulmonary disease samples were collected. All sputum samples were sent for acid-fast bacilli smear, SAT, culture and drug susceptibility testing (DST) by the BACTEC(TM) MGIT(TM) 960 system...

BACKGROUND: Measuring the size of the infectious pool of tuberculosis (TB) is essential to understand the burden and monitor trends of TB control program performance. This study applied the concept of TB management time to estimate and compare the size of the TB infectious pool between 2009 and 2014 in West Gojjam Zone of Amhara Region, Ethiopia. METHODS: New sputum smear-positive and smear-negative pulmonary TB (PTB) and retreatment cases who attended 30 randomly selected public health facilities in West Gojjam Zone from October 2013 to October 2014 were consecutively enrolled in the study...

RATIONALE: Lymph node is a preferred site for extrapulmonary tuberculosis (TB). In the thorax, mediastinal tuberculous lymph nodes can erode adjacent structures such as heart, aorta, and esophagus, forming fistula, and causing fatal consequences. However, tuberculous bronchonodal fistula as a complication of lymph node TB in adults is rarely known in terms of imaging or clinical findings. Here, a case of isolated tuberculous bronchonodal fistula appearing as the first presentation of TB in a 74-year-old male with systemic lupus erythematosus (SLE) is reported...

Silicosis is the oldest know occupational pulmonary disease. It is a progressive disease and any level of exposure to respirable crystalline silica particles or dust has the potential to develop into silicosis. Silicosis is caused by silica particles or dust entering the lungs and damaging healthy lung tissue. The damage restricts the ability to breathe. Exposure to silica increases a worker’s risk of developing cancer or tuberculosis. This special report will provide background history of silicosis in the U...

Urogenital tuberculosis does not have pathognomonic symptoms, so diagnostic errors are quite common. This systematic review of literature was conducted to identify the causes and estimate the incidence of erroneous diagnoses. We critically evaluated some articles in which the authors describe observations of urogenital tuberculosis as rare and unusual because they never encountered this disease, but in fact that were typical manifestations of genitourinary tuberculosis. The authors analyzed and illustrated the features of urinary tuberculosis in patients with pulmonary tuberculosis, differential diagnosis of urogenital tuberculosis and kidney cancer and male genitourinary organs, described errors in the diagnosis of urethral, testicular, penile, prostatic and epididymal tuberculosis...

The incidence of three granulomatous response diseases-sarcoidosis, tuberculosis, and non-tuberculous mycobacterial pulmonary disease-differ markedly in African-Americans versus Caucasians. In reviewing a large compendium of non-cystic-fibrosis bronchiectasis, we noted that complicating infection with non-tuberculous mycobacteria was relatively infrequent among individuals of African-American descent, confirming previous observations of their inherent resistance. Disease-specific variance among African-Americans in the efficacy of their granulomatous response suggests a nexus, a mediating, immunological mechanism...

REVIEW
Tahuanty Pena, Julia Klesney-Tait
Mycobacterial infections are uncommon in solid organ and hematopoietic stem cell transplant recipients but carry significant morbidity and mortality. Donor screening strategies for tuberculosis should be emphasized in high-risk populations. Both tuberculosis and nontuberculous mycobacterial infections can have pulmonary and extrapulmonary manifestations of infections. Recommended treatment regimens typically involve multiple drugs with significant adverse effects and drug interactions.

BACKGROUND: Blood based Interferon-(IFN)-γ release assays (IGRAs) have a poor predictive value for the development of tuberculosis. This study aimed to investigate the correlation between IGRAs and pulmonary immune responses in tuberculosis contacts in Germany. METHODS: IGRAs were performed on bronchoalveolar lavage (BAL) cells and peripheral blood from close healthy contacts of patients with culturally confirmed tuberculosis. Cellular BAL composition was determined by flow cytometry...

We report the case of a patient with penetrating chest trauma (right chest) who had undergone a left pneumonectomy due to pulmonary tuberculosis 24 years ago. We performed an emergent thoracotomy, finding an opening of the penetrating wound in a lower-lobe basal segment of the right lung. A stapled tractotomy was performed along the tract. Bleeding control and air-leakage control was done easily and rapidly. The patient was discharged without any complications on the seventh day of admission. Tractotomy can be a good option for treating penetrating lung injuries in patients with limited lung function who need emergent surgery...

Rasmussen's aneurysm, a very rare complication of active pulmonary tuberculosis (TB), is a pulmonary artery aneurysm adjacent to or within a tuberculous cavity. It may lead to rupture and life threatening massive hemoptysis, an uncommon but challenging medico-surgical emergency. This complication warrants attention in view of the resurgence of tuberculosis and increasing occurrence of multi-drug resistant TB, especially in resource-poor, high-TB burden countries like India. We present a case of an elderly man who presented to the emergency room with low-grade fever, cough and hemoptysis...

Case: A 75-year-old woman presented with a 10-day history of intermittent fever, general fatigue, and progressive dyspnea. Although she had a low PaO2/FIO2 ratio, the cause of acute respiratory distress syndrome was not clear until day 9 in hospital. Outcome: We treated the patient with direct hemoperfusion with a polymyxin B-immobilized fiber column incidentally; the PaO2/FIO2 ratio improved following this therapy. Acid-fast bacilli, which were not seen in the sputum on admission, were detected in cultures from sputum, urine, bone marrow, liver biopsy, and blood samples, with a real-time polymerase chain reaction assay confirming tuberculosis...
