The 24th Special Volume of the noted international series Recent Advances in Pediatrics aims to cover topical issues in pediatric respiratory diseases. The 2S peer-reviewed, evidence-based and state-of-the-art chapters contributed by 31 experts, drawn from India and abroad, attempt to review the depth and breadth of knowledge in the field of pediatric respiratory diseases with special reference to its applicability in the Indian subcontinent. Each and every chapter is remarkable in its excellence, providing a stimulating, matured, informed, and, not infrequently, even provocative update. Understandably, such an approach is befitting when the goal is not only to inform but also to motivate discussion, interaction, research and innovation. In keeping with the professed policy of the RAP series, a multidisciplinary approach with an eye on the future continues to occupy pride of place in this volume as well. While providing an academic feast in a holistic manner, the treatise should be a landmark in translating pediatric advances from bench side to bedside and beyond to the community, especially in the Indian subcontinent.
