Primary tubercular liver abscess in an immunocompetent adult: a case report
<p>Abstract</p> <p>Introduction</p> <p>Isolated primary tubercular abscess is one of the rare forms of extrapulmonary tuberculosis. A greater awareness of this rare clinical entity may help in commencing specific evidence-based therapy quickly and preventing undue morbidity and mortality.</p> <p>Case presentation</p> <p>A 30-year-old man, of Asian origin, developed a hepatic tubercular abscess which was not associated with any pulmonary or gastrointestinal tract foci of tuberculosis. An ultrasonogram of the abdomen showed an abscess in the right lobe of his liver which was initially diagnosed as an amoebic liver abscess. Subsequently, the pus from the lesion yielded <it>Mycobacterium tuberculosis </it>using the BACTEC TB 460 instrument and <it>Mycobacterium tuberculosis </it>deoxyribonucleic acid by polymerase chain reaction. The patient was started on systemic antitubercular therapy to which he responded favorably.</p> <p>Conclusion</p> <p>This report emphasizes the fact that, although a tuberculous liver abscess is a very rare entity, it should be included in the differential diagnosis of unknown hepatic mass lesions.</p
Multi Drug Resistant Tuberculous Meningitis in Pediatric Age Group
Objective: Past decade has seen increase in cases of tuberculous
meningitis (TBM) and multidrug resistance in such cases. The mortality
rate for a mismanaged TBM is very high which increases manifold in
presence of associated complicating factors. The present study was thus
planned to evaluate the prevalence of MDR-TBM and look for associated
complicating factors and carry out drug sensitivity pattern in all
culture positive isolates. Methods: One hundred cerebro-spinal fluid
(CSF) samples from children clinically suspected of having TBM were
collected and processed for detection of Mycobacterium tuberculosis by
conventional methods like Ziehl-Neelsen (ZN) staining, Lowenstein-
Jensen (LJ) culture and newer method like BACTEC 460 TB culture.
Antimicrobial susceptibility was performed on all culture positive
isolates by BACTEC 460 TB system. Findings: Twenty two cases could be
diagnosed as definitive TBM based on BACTEC culture. Of these 22 cases,
six cases (27.3%) were positive by ZN staining and/or LJ culture. Of
all isolates tested for drug sensitivity 18 were sensitive to all four
drugs whereas 4 isolates were resistant to more than one drug.
Conclusion: Since the prevalence of MDR-TBM is very high we conclude
that all CSF samples should be subjected to sensitivity testing to
diagnose it at an early time and determine its sensitivity pattern in
view of its very high mortality
