Even with the use of maximum pharmacological treatment, asthma still remains uncontrolled in some cases. For such cases of uncontrolled asthma, a novel therapy--Bronchial Thermoplasty (BT)--has shown some promising results over the past few years. BT is application of controlled radiofrequency heat via catheter inserted through a flexible bronchoscope, to the bronchial walls. ⋯ But the benefit observed was too small to be clinically significant. Follow up (two to five years) results of these BT trials did not show any significant long-term adverse event related to BT. However, further independent large randomized controlled trials and results of application of BT in real hospital settings are needed to define its role in asthma management.

Comparative Study Clinical Trial
A pilot study of same day sputum smear examination, its feasibility and usefulness in diagnosis of pulmonary TB.
A large number of tuberculosis cases are continuously being reported from India and other developing countries leading to high morbidity and mortality. In spite of many newer tests available for diagnosing a case of tuberculosis, smear microscopy of sputum is still the preferred test under programmatic conditions. The current national and international guidelines recommend two sputum smear examinations in two days for diagnosing cases of tuberculosis, which is time-consuming, tedious, needs multiple visits, leading to high dropout of infectious cases. In the background of existing limitations of smear microscopy, we attempted to complete the diagnosis of tuberculosis on same day by serial collection of the spot sputum specimen and analyze its advantages, feasibility and viability. ⋯ Same day smear microscopy for diagnosing tuberculosis by a proposed new method of smear examination in the case of suspected tuberculosis seems not a promising step towards improving the quality of sputum smear examination. The results of sensitivity and specificity of the two approaches were not similar. More than eighty per cent responded in favour of same day sputum delivery system and getting result on same day. This study can be confirmed on larger scale and preference of patients can be examined in peripheral laboratory also before taking it up for consideration in the national tuberculosis programme.
