Lack of well referenced, revised and standardized books on TB has led to formulation of this book sharing the clinical experiences of global professionals on TB. 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 challenges in diagnosis and management of MDR-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. The book covers topics like extra pulmonary tuberculosis and miscellaneous. Worldwide revival of MDR-TB shows that fight against this disease will continue in the coming years. 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).
