Tuberculosis is a pulmonary disease with an especially high mortality rate in immuno-compromised populations, specifically children and HIV positive individuals. The causative agent, Mycobacterium tuberculosis (Mtb), is a very slow growing and difficult organism to work with, making both diagnosis and development of effective treatments cumbersome. We utilize a fiber-optic fluorescence microendoscope integrated with a whole-body imaging system for in vivo Mtb detection. The system exploits an endogenous enzyme of Mtb (β-lactamase, or BlaC) using a BlaC-specific NIR fluorogenic substrate...

Abstract/ Resumo Behcet's disease (BD) is a multisystem inflammatory disorder characterized by recurrent oral and genital ulcers, skin lesions and uveitis. The nervous system involvement of BD, neuro-Behcet's disease (NBD), is one of the important causes of mortality of the disease. Herein, we present a 29-year-old male with parenchymal NBD who has progressed rapidly and was managed with an uncommon aggressive immunosuppresive combination therapy. The patient first presented six years ago with vertigo and difficulty in talking and walking...

Although serine proteases are important mediators of Mycobacterium tuberculosis (Mtb) virulence, there are currently no tools to selectively block or visualize members of this family of enzymes. Selective reporter substrates or activity-based probes (ABPs) could provide a means to monitor infection and response to therapy using imaging methods. Here, we use a combination of substrate selectivity profiling and focused screening to identify optimized reporter substrates and ABPs for the Mtb "Hydrolase important for pathogenesis 1" (Hip1) serine protease...

BACKGROUND: A 'watering can penis' secondary to penile tuberculosis is an extremely rare clinical entity. Retrograde Urethrography - Voiding Cystourethrography evaluation of the urethra and the urinary bladder plays a very important role in the diagnostics as well as further management of the urethral abnormalities. To the best of our knowledge, this is only the second case in literature where a 'watering can penis' was noted secondary to penile TB. This is also the first documented case of 'watering can penis' as a consequence of venereal transmission of TB...

Intraocular tuberculosis presents a diagnostic challenge because of its protean clinical manifestations. Thus, it becomes imperative to distinguish chorioretinal inflammation due to tuberculosis from other infectious as well as non-infectious posterior uveitis since the clinical manifestations of these entities may be quite similar. With advancing technology, a number of novel imaging modalities are available today that enable in vivo near-histologic assessment of the chorioretinal tissue, greatly aiding the clinician in establishing a diagnosis and monitoring the therapeutic response of tubercular lesions...

Extrapulmonary tuberculosis refers to Mycobacterium tuberculosis involving organs other than the lungs (eg, pleura, lymph nodes, genitourinary tract, abdomen, skin, joints and bones, or meninges). In non-HIV-endemic areas, where reactivation is the predominant mechanism of tuberculosis, pleural involvement occurs in 4% of cases. We present an extremely rare case of a 62-year-old immunocompetent patient with pleural tuberculosis confirmed by surgical pleural biopsies, who presented with a large mediastinal mass and evidence of pulmonary artery invasion on CT scanning and endobronchial ultrasonography imaging, highlighting a unique and malignant-like character of the disease...

BACKGROUND: Tuberculosis (TB) prevalence surveys offer a unique opportunity to study health seeking behaviour at the population level because they identify individuals with symptoms that should ideally prompt a health consultation. OBJECTIVE: To assess the health-seeking behaviour among individuals who were presumptive TB cases in a national population based TB prevalence survey. METHODS: A cross sectional survey was conducted between 2013 and 2014 among 66 survey clusters in Zambia...

We report the case of a parascapular abscess revealing primary tuberculosis of the posterior arch in a 31-year-old man. Sectional imaging is essential in order to detect the different lesions of this atypical spinal tuberculosis as osteolysis of the posterior arch extendible to vertebral body, osteocondensation, epidural extension which is common in this location, and high specificity of a zygapophysial, costo-vertebral or transverse arthritis.

There is an urgent need to discover new anti-tubercular agents with novel mechanisms of action in order to tackle the scourge of drug-resistant tuberculosis. Here, we report the identification of such a molecule - an AminoPYrimidine-Sulfonamide (APYS1) that has potent, bactericidal activity against M. tuberculosis. Mutations in APYS1-resistant M. tuberculosis mapped exclusively to wag31, a gene that encodes a scaffolding protein thought to orchestrate cell elongation. Recombineering confirmed that a Gln201Arg mutation in Wag31 was sufficient to cause resistance to APYS1, however, neither overexpression nor conditional depletion of wag31 impacted M...

Due to an increasing amount of patients on immunosuppressive treatment, the number of tuberculosis (TB) of atypical course and extrapulmonary tuberculosis cases increase. Locomotor system is a place of every fifth case of extrapulmonary TB. Because of lack of characteristic symptoms, as well as rare co-occurrence of active lung lesions in radiological imaging, proper diagnosis is hard to establish. We present a case of patient on immunosuppressive therapy due to myositis, in whom we diagnosed musculoskeletal tuberculosis in form of involvement of tendon sheath and formation of synovial cyst...

INTRODUCTION: Tuberculosis remains a major public health problem in developing countries. Diagnosing extrapulmonary tuberculosis can be difficult, as it requires a higher index of suspicion than primary tuberculosis. Extrapulmonary tuberculosis may mimic malignancies and many other diseases, so it should be included in the differential diagnosis. Here, we present a case of extrapulmonary tuberculosis associated with Pott's disease and hip arthritis in a patient who recovered after 12 months of antituberculosis therapy...

We evaluate the performance of Xpert MTB/RIF for the diagnosis of extrapulmonary tuberculosis (EPTB) in China. The performance of Xpert was evaluated compared to the composite reference standard (CRS), drug susceptibility testing (DST), and imaging examination. The overall sensitivity and specificity of Xpert were 64.1% (195/304) and 100% (24/24), respectively, using CRS as the gold standard. The sensitivity was significantly higher than that of culture for pus (P<0.05). The proportion of EPTB-positive cases diagnosed by imaging was two times more than that diagnosed using Xpert; however, 6 out of 19 cases may have been overdiagnosed by imaging...
