INTRODUCTION: Tuberculosis (TB) of the ankle is an uncommon presentation of extrapulmonary infection. The early diagnosis of TB arthritis of the ankle is difficult because of the uncommon site, the ability of TB to mimic other disorders and, all too common, lack of awareness of about this infection in ankle joint. CASE REPORT: A 30-year-old male presented with a 1-year history of right ankle pain and swelling. He denied any history of recent infection but had had recurrent ankle pain that had been treated accordingly...

Tuberculosis (TB) is a serious global health problem, although it is easily preventable and curable. The prevalence of TB is caused by a lack of simple, rapid, cheap, and effective TB diagnostic tests. In this study, we have established a novel liquid crystal (LC)-based immunosensor to diagnose TB in clinical specimens. The clinical serum samples were incubated on a TB antigen-immobilized substrate, and their optical LC responses were observed using a polarized light microscope. Specific binding of anti-TB antibodies to the TB antigen-immobilized surface only occurred in clinical specimens from TB patients, inducing the disruption of the orientation of LCs...

Background: Tuberculous meningitis (TBM) leads to death or disability in half the affected individuals. Tools to assess severity and predict outcome are lacking. Neuro-specific biomarkers could serve as markers of the severity and evolution of brain injury, but have not been widely explored in TBM. We examined biomarkers of neurological injury (neuromarkers) and inflammation in pediatric TBM and their association with outcome. Methods: Blood and cerebrospinal fluid (CSF) of children with TBM and hydrocephalus taken on admission and over 3 weeks were analysed for neuromarkers S100B, neuron-specific enolase (NSE) and glial fibrillary acidic protein (GFAP), and multiple inflammatory markers...

Positron emission tomography and computed tomography imaging (PET/CT) is an increasingly valuable tool for diagnosing tuberculosis (TB). The glucose analog [(18)F]fluoro-2-deoxy-2-d-glucose ([(18)F]-FDG) is commonly used in PET/CT that is retained by metabolically active inflammatory cells in granulomas, but lacks specificity for particular cell types. A PET probe that could identify recruitment and differentiation of different cell populations in granulomas would be a useful research tool and could improve TB diagnosis and treatment...

Protein fibrillation is associated with a number of neurodegenerative diseases. Nevertheless, several proteins not related to disease can also form fibrils in vitro under specific conditions. In the present study, we demonstrate the reversible fibrillation of a globular protein that is modulated by salt under physiological pH. Mycobacterium tuberculosis Isocitrate lyase (MtbICL) is a crucial enzyme involved in the glyoxylate shunt and a potential drug target against M. tuberculosis infection. Under physiological pH, the enzyme self-assembles into a fibrillar structure in the absence of salt in vitro...

Tuberculous meningitis (TBM) is associated with significant complications of central nervous system. It is accompanied by nonspecific and heterogeneous clinical symptoms. We focused on the significance of early diagnosis and prompt treatment. We describe a case of TBM in a 19-year-old Asian female. She had a progressive motor weakness with no sensory findings. She was started on antituberculous therapy. Her magnetic resonance imaging (MRI) contrast of dorsolumbar spine showed syringomyelia. Her culture and sensitivity for Mycobacterium tuberculosis (MTB) came negative...

(18)F-fluorodeoxyglucose positron emission/computed tomography ((18)F-FDG PET/CT) imaging, an established procedure for evaluation of malignancy, reports an increased (18)F-FDG uptake in acute or chronic inflammatory condition. Lymph node tuberculosis (LNTB) is the most common form of extrapulmonary tuberculosis. However, the absence of clinical symptoms and bacteriological basis makes it difficult to diagnose. In the current case report, two patients with LNTB mimicking malignant lymphoma are presented by (18)F-FDG PET/CT...

Traditional treatments for spinal tuberculosis (TB) involve chemotherapy and surgery. In the present study, it has been identified that chemotherapy lasting <6 months [ultra-short course chemotherapy (UCCT)], rather than the 6-18 months of the traditional regimen, is effective in sustaining TB clearance following complete surgical debridement. This current study aims to compare the changes in peripheral blood gene expression prior to and following UCCT, subsequent to complete debridement of spinal TB lesions...

REVIEW
Siddharth Yadav, Prabhjot Singh, Ashok Hemal, Rajeev Kumar
Genitourinary Tuberculosis (GUTB) is the second most common extra-pulmonary manifestation of tuberculosis (Tb) and an isolated involvement of genital organs is reported in 5-30% of the cases. Genital involvement results from primary reactivation of latent bacilli either in the epididymis or the prostate or by secondary spread from the already infected urinary organs. The epididymis are the commonest involved organs affected primarily by a hematogenous mode of spread. Tb is characterized by extensive destruction and fibrosis, thus an early diagnosis may prevent function and organ loss...

A 26-year-old female from India presented with progressive, unremitting low back pain for over 1 year. She had been treated unsuccessfully for left-sided sacroiliitis, pelvic floor dysfunction, ankylosing spondylitis and seronegative spondyloarthritis. MRI lumbar spine showed a Schmorl node with surrounding marrow oedema at L4, the relevance of which is not clear in literature. One year after initial presentation, a biopsy of this lesion revealed culture positive diagnosis of spinal tuberculosis. Despite advances in imaging, delayed diagnosis is not uncommon in spinal tuberculosis (TB)...
