In India, the quality of care that tuberculosis (TB) patients receive varies considerably and is often not in accordance with the national and international standards. In this article, we provide an overview of the third (latest) edition of the International Standards of Tuberculosis Care (ISTC). These standards are supported by the existing World Health Organization guidelines and policy statements pertaining to TB care and have been endorsed by a number of international organizations. We call upon all health care providers in the country to practice TB care that is consistent with these standards, as well as the upcoming Standards for TB Care in India (STCI).

Tubercular cold abscesses secondary to neighbouring bone involvement are a well-known clinical manifestation of extra-pulmonary tuberculosis. However, primary soft tissue tuberculous abscesses with no pulmonary involvement in immuno-competent patients are very uncommon. A rare case of multiple primary intrathoracic and extraperitoneal soft tissue tuberculous abscesses and mediastinal lymph node tuberculosis with no pulmonary involvement is reported. This case demonstrates the need for a high index of suspicion for such rare presentations of extra-pulmonary tuberculosis in patients from endemic areas.

The Smear Conversion Rate (SCR) is an operational indicator for the Directly Observed Treatment Short-course (DOTS) strategy of Revised National Tuberculosis Control Programme (RNTCP) in India. The present study was undertaken to determine the relationship between sputum smear grading and smear conversion rate among the Category I smear positive pulmonary tuberculosis patients undergoing DOTS. ⋯ Patients with higher grades of sputum positivity at the beginning of the treatment have significantly lower SCR at the end of intensive phase and even after extending the intensive phase for one month. Hence, they are likely to remain infectious for a longer duration and continue to transmit infection in the community. Therefore, these patients demand to have more stringent self-precautionary measures to break the chain of infection in the community. The SCR at two months and three months as an operational indicator should be given more importance rather than being practised only as a documentation and academic exercise. The patient should be investigated for the possible co-morbid conditions and drug resistance which could be a cause for the persistent sputum smear positivity at two and three months and hence poor treatment outcome.

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.
