PREFACE

Internal medicine is a vast and complicated field that is based on strong scientific and clinical foundations. Moreover it is rapidly evolving and one needs periodic updating and catching up with the state of the art knowledge. Providing a comprehensive review of internal medicine is not only difficult but almost impossible, as the field is vast and extensive. Despite this limitation, the authors have tried to provide a basic framework for working knowledge of Internal medicine. Essential topics are included as much as possible, and some chapters and topics are dealt extensively, such as Infectious diseases in general and Acute febrile illnesses, Tuberculosis, and HIV/AIDS in particular, as these are known to be the commonest causes of morbidity and mortality in developing countries, like ours. Even though a number of individuals have contributed in the original document of this lecture note, as more than 3 years have elapsed, most of the topics are reviewed, and some topics are completely rewritten, to include new developments and the state of the art scientific knowledge. This lecture note has been written primarily for Health officer students; however it can also be used by medical students and all other health science students who deal with patients, who have medical illnesses.
