INTRODUCTION: Extrapulmonary tuberculosis (EPTB) is increasingly frequent in developed countries. When it is not clinically suspected, samples are not collected for culture and the only material available is a tissue paraffin block. OBJECTIVE: The aim of this study was to evaluate FluoroType MTB (FT-MTB) and GenoType MTBDRplus methods for the detection of Mycobaterium tuberculosis complex in paraffin-embedded biopsies comparing the results to tuberculosis diagnosis...

Histoplasma capsulatum is a saprophytic fungus that in immunocompetent individuals causes self-limited pulmonary infection; however, in immunosuppressed patients involvement of the reticuloendothelial system, alimentary tract, urinary tract, and central nervous system is fairly common. Rarely patients present with bilateral adrenal masses which mimic tuberculosis and metastasis on radiology because of associated central necrosis. Ultrasound guided FNAC aided by special stains like Periodic Acid Schiff (PAS) and Gomori Methenamine Silver (GMS) may help in early diagnosis in such dubious cases...

Psoriatic patients with latent tuberculosis infection (LTBI) need a prophylaxis before starting a treatment with biological drugs. The aim of this study is to investigate the safety and efficacy of prophylaxis of LTBI in psoriatic patients receiving long-term biological drugs. The study included 56 patients (42 male and 14 female) affected by moderate-to-severe psoriasis (mean PASI: 12.8 ± 6.9 SD) treated with anti-TNF-α and/or anti IL 12, 23 and/or anti-CD11 drugs with a diagnosis of LTBI. LTBI diagnosis was based on tuberculin skin test and/or QuantiFERON TB Gold test positivity and chest X-ray suggestive, without clinical, or microbiological evidence of active disease...

BACKGROUND: The impact of tuberculosis (TB) is exacerbated in Africa because of the human immunodeficiency virus (HIV) pandemic. Pulmonary tuberculosis (PTB) diagnosis is difficult in HIV-infected patients and negative sputum results are more common which leads to diagnostic delay and increases morbidity and mortality. Extra-pulmonary samples such as stool may be easier to obtain and our approach may therefore significantly improve PTB detection in people living with HIV. OBJECTIVE: To detect Mycobacterium tuberculosis from the stool of HIV sero-positive individuals suspected of pulmonary TB...

In resource-limited countries, the diagnosis of pulmonary tuberculosis (TB) is based on clinical findings, chest radiography and the demonstration of acid-fast bacilli in sputum. Few data are available on the use of ultrasound (US) to diagnose pulmonary TB. Chest US was performed in patients with lung TB from a rural African setting, to look for signs of the disease and to clarify the role US may have in the diagnosis of pulmonary TB. Sixty adult patients diagnosed with lung TB underwent chest US. All patients had abnormal findings...

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...

The peritoneum is one of the common extrapulmonary sites of tuberculosis infection. Patients with underlying end-stage renal or liver disease are frequently complicated by tuberculous peritonitis; however, the diagnosis of the tuberculous peritonitis is difficult due to its insidious nature, well as its variability in presentation and limitation of available diagnostic tests. Once diagnosed, the preferred treatment is usually antituberculous therapy in uncomplicated cases. However, surgical treatment may also be required for complicated cases, such as small bowel obstruction or perforation...

RATIONALE: Palisaded neutrophilic and granulomatous dermatitis (PNGD) is a benign, inflammatory dermatosis with distinct histopathological features often observed in patients with systemic diseases. There were no reports of PNGD without underlying systemic diseases as an underlying cause of hypercalcemia. Herein, we report a case of a 62-year-old man with hypercalcemia due to PNGD, but with no underlying systemic diseases, including tuberculosis, sarcoidosis, or vasculitis. PATIENT CONCERNS: Laboratory tests showed an elevated C-reactive protein level, an elevated corrected calcium level, a normal 25-hydroxyvitamin D level, and an elevated 1,25-dihydroxyvitamin D level...

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)...

Tuberculosis is the leading cause of chronic granulomatous epididymo-orchitis in the Asian population. A retrospective analysis of 40 patients diagnosed with granulomatous or tubercular epididymo-orchitis on fine-needle aspiration (FNA) was carried out. May Grünwald giemsa, haematoxylin and eosin and Ziehl Neelsen stained smears were evaluated. Of 40 patients studied, aspiration smears showed epithelioid cell granulomas with caseation in 17, granulomas alone in 19 and caseation only in four. Acid fast bacilli were seen in 15...

Bone tuberculosis may mimic malignant tumor. We here report the case of a 4-year old child with bone tuberculosis mimicking femoral osteosarcoma. The diagnosis was rectified thanks to anatomo-pathologic examination. This case study underlines the importance of knowing the clinical and radiological aspects of bone tuberculosis which can mimic malignant tumor. In order to avoid any delay in diagnosis, surgeons, pediatricians and radiologists should know that tuberculosis can mimic many pathologies, both clinically and radiologically...

Tuberculous involvement of the spinal cord parenchyma is an exceedingly rare clinical entity; even more so is concurrent intracranial tuberculosis (TB). Spinal intramedullary TB presents with a characteristic subacute myelopathy, with slowly progressive paraplegia, sensory deficits, and/or bowel and bladder dysfunction. Diagnosis is strongly suspected with a clinical history of known TB in conjunction with characteristic findings on magnetic resonance imaging. Management involves multi-agent antitubercular chemotherapy without or with operative intervention...

OBJECTIVES: The diagnosis of peripheral tubercular lymphadenopathy (TBLN) in pediatric patients is often a challenge because features evident on fine-needle aspiration cytology (FNAC) or tissue biopsy can be deceptive for the reason that they result from an immunological response. This study aimed to evaluate polymerase chain reaction (PCR) for Mycobacterium tuberculosis complex (MTBC) in pediatric patients under clinical suspicion for TBLN and to assess its role in the evaluation of cases cytodiagnosed as reactive lymphoid hyperplasia...

Rapid and accurate diagnosis of tuberculosis (TB) is essential to control the disease. The conventional microbiological tests have limitations and there is an urgent need to devise a simple, rapid and reliable point-of-care (POC) test. The failure of TB diagnostic tests based on antibody detection due to inconsistent and imprecise results has stimulated renewed interest in the development of rapid antigen detection methods. However, the World Health Organization (WHO) has emphasized to continue research for designing new antibody-based detection tests with improved accuracy...
