Essentials of Clinical Medicine is a textbook intended for both undergraduate students to prepare for their exams reading only one book as well as a quick review for postgraduate trainees and practicing physicians. This book is of modest size, containing chapters of clinical medicine, but is sufficiently comprehensive and up to date, providing the reader not only basic concepts of clinical medicine but also sound medical practices. The book is written in easy-to-understand language, important points in bold, and most of the causes and lists in the form of tables or bullets. Local diseases have been emphasized. Medicine is an ever-changing science with voluminous growth in all fields rapidly.
