A Case of Pulmonary MALToma Camouflaged Within Invasive Pulmonary Aspergillosis.

A 59-year-old non-smoking male, with a known case of COPD (chronic obstructive pulmonary disease), treated pulmonary tuberculosis with Category 1 antitubercular drugs (six-month regimen) and was admitted with repeated bouts of moderate haemoptysis (~60 mL/day) for three days. The patient had a history of self-limiting occasional mild haemoptysis (~20 mL) over three years. An HRCT chest revealed a left upper lobe fibro-cavitary lesion with an intracavitary mass (air crescent sign), adjacent pleural thickening and fibrosis.

Quantitative estimation of isoniazid content in the commercially available and government-supplied formulations.

Background: Multi-drug resistant tuberculosis is on the rise, resulting in treatment failure. One potential reason for drug resistance is the substandard quality of manufactured antituberculous drugs. This study aims at finding out the difference in the quantity of isoniazid between government-supplied tablets and commercially available tablets.
