1.  A case-control study of bidi smoking and bronchogenic carcinoma 
Annals of Thoracic Medicine  2010;5(4):238-241.
OBJECTIVE:
To evaluate the risks imposed by tobacco smoking, in particular, bidi smoking, in the development of lung cancer.
METHODS:
Two hundred eighty-four histologically confirmed patients of bronchogenic carcinoma and 852 controls matched for age, sex, and socioeconomic status were interviewed according to a predesigned questionnaire. Effects of individual variables defining the various aspects of tobacco smoking, in particular, bidi smoking, were assessed using logistic regression models.
RESULTS:
81.3% cases of bronchogenic carcinoma were ever smokers as compared with 42.2% among controls. The odd ratios for ever smoking, bidi smoking, and cigarette smoking were 5.9 (confidence interval [CI] 4.3, 8.4), 6.1 (CI 4.3, 8.7), and 5.3 (CI 2.7, 10.4), respectively.
CONCLUSION:
Bidi smoking poses a very high risk for lung cancer even more than that of cigarette smoking.

2.  A case-control study of tobacco smoking and tuberculosis in India 
Annals of Thoracic Medicine  2009;4(4):208-210.
OBJECTIVES:
To evaluate the role of smoking as a risk factor for the development of pulmonary tuberculosis.
MATERIALS AND METHODS:
A total of 111 sputum smear—positive patients of pulmonary tuberculosis and 333 controls matched for age and sex were interviewed according to a predesigned questionnaire.
RESULTS:
The adjusted odd ratio of the association between tobacco smoking and pulmonary tuberculosis was 3.8 (95% confidence interval, 2.0 to 7.0; P value, <.0001). A positive relationship between pack years, body mass index and socioeconomic class was also observed.
CONCLUSION:
There is a positive association between tobacco smoking and pulmonary tuberculosis.

Annals of Thoracic Medicine  2008;3(3):104-105.
Spontaneous pneumothorax complicating pregnancy is rare. Only 55 cases have been reported till now. We describe a case of a 30-year-old Indian woman with spontaneous pneumothorax during her 28th week of pregnancy.
