Data is being readily compiled from across the globe at a very fast rate about the efficiency of standardized treatment regimens for different forms of tuberculosis (TB) including drug-resistant TB, drug-sensitive TB and latent TB infection. At a time when we are facing the threat of multi drug-resistant TB [MDR-TB], development of extensively drug-resistant TB [XDR-TB] has threatened to undermine global efforts at TB control. This book covers in-depth analysis of all the developments and aspects of the diagnosis and management of MDR-TB. The transforming clinical presentation of TB, progresses in laboratory, therapeutic measures, imaging diagnostic modalities and rise of MDR-TB all indicate an imperative need for a revised book on TB. Moreover, while physicians face the fatal disease of TB in their clinical practice, there have been several misunderstandings and controversies regarding various issues for the management and diagnosis of TB. Lack of well referenced, revised and standardized books on TB has led to foundation of this book sharing the clinical experiences of global professionals on TB. The book covers topics like immune-pathology, epidemiology, identification, treatment and novel developments for TB, focusing on the global perspective of TB. Worldwide revival of MDR-TB shows that fight against this disease will continue in the coming years. TB has great significance in terms of social, financial and medical aspects and this book covers all the aspects regarding the treatment of TB. The aim of this book is to serve as a valuable source of reference and guidance for the people who are involved in the management of TB as well as for the practicing physicians (especially, pulmonologists and internists).
