The Manual was created with consideration for the challenges faced by postgraduate medical students who must study for exams on a strict timeline and cover a wide range of material. The Manual covers both an approach to the systems and a point-by-point description of typical disorders. A substantial amount of critical, crucial, as well as indispensable medical information has been provided, along with several clinical illustrations, tables, and flowcharts that are very enlightening and simple to remember. The Manual is intended to work as a textbook for undergraduate students, a helpful reference for postgraduate students (MD/DNB), and a crucial clinic-table resource for all currently licenced physicians.
