Brain tuberculoma has previously accounted for up to a third of new intracranial lesions in areas endemic with tuberculosis, but is unexpected in the United States and other Western countries with improved disease control. Here we show the importance of considering this diagnosis in at-risk patients, even with no definitive pulmonary involvement. We describe a young man who presented with parti...

Lymphadenitis is the most common extrapulmonary manifestation of tuberculosis. It remains both diagnostic and therapeutic challenge because it mimics other pathologic processes and yields inconsistent physical and laboratory findings. Diagnosis is difficult often requiring biopsy. A thorough history and physical examination, staining for acid-fast bacilli, fine-needle aspiration and PCR are hel...

BACKGROUND To study the status of zinc as a micronutrient in pulmonary tuberculosis, in our population, with the aim to see the effectiveness of therapy. METHODOLOGY This prospective study includes 50 patients with pulmonary tuberculosis and 30 subjects as the control group. The patients were placed into three stages (1 to 3) on the basis of chest radiographic findings. Serum zinc levels were...

Pseudomembranous colitis is known to develop with long-term antibiotic administration, but antitubercular agents are rarely reported as a cause of this disease. We experienced a case of pseudomembranous colitis associated with rifampin. The patient was twice admitted to our hospital for the management of frequent bloody, mucoid, jelly-like diarrhea and lower abdominal pain that developed after ...

The condensation of chlorides of substituted pyrazinecarboxylic acids with ringsubstituted anilines yielded twelve substituted pyrazinecarboxylic acid amides. The synthetic approach, analytical, and lipophilicity data of the newly synthesized compounds are presented. Two antituberculosis assays were used. Firstly, the antimycobacterial activity against four different Mycobacterium strains in a ...

Nonreplicating and metabolically quiescent bacteria are implicated in latent tuberculosis infections and relapses following "sterilizing" chemotherapy. However, evidence linking bacterial dormancy and persistence in vivo is largely inconclusive. Here we measure the single-cell dynamics of Mycobacterium tuberculosis replication and ribosomal activity using quantitative time-lapse microscopy and ...

The diagnosis of tuberculosis in immunocompromised hosts is often difficult as the hosts have atypical tuberculosis symptoms. The current study presents a case of scrofula and pulmonary tuberculosis with acute myelocytic leukemia (AML). As the disease became aggravated, the patient presented with fever, hemophagocytosis in the bone marrow, lymphadenopathy of the supraclavicular fossa, and media...

bcg (bacille calmette–guérin) vaccine is administered worldwide to prevent severe forms of tuberculosis. it is considered to be safe; however, occasional complications are seen. the most serious complication is bcgosis. we report a case of bcgosis with granulomatous hepatitis and acid-fast bacilli in liver and spleen. we treated the patient with antituberculosis drugs without any response to tr...
