The students and practitioners would simultaneously hear the audio lecture of the chapter with the respective chapter notes in front. Once they have understood the chapter with the help of the notes, they need not go through the exercise again. All that needs to be done is to have a glance at the points and tables in the chapter. The topics covered are the A to Z of allergy, both from practical and postgraduate examination points of view. The book is a must-read for postgraduate students of all specialties to answer allergy-related questions. It is an eye opener for the practitioners and for the allergy specialists a ready refresher on their table top.As a stakeholder of allergies in the community, I could sense the void in the knowledge of allergic diseases at every level. Hence, a need was created to write lecture notes. The characteristic feature is the points followed by the explanation.During their studies, students need to go through every line and understand the subject. However, during examination or revision within a limited time, all they need to do is read the points and key summary. The book comes with an audio lecture by each of the authors to provide clarity on the subject.The practitioners lack time for the detailed reading of a reference book on a subject never taught during college. This book provides the information needed to manage the patient at hand. A set of OSCE-type questions is provided to stimulate your mind. All in all,the information is just enough for not only to get through examinations but also to manage the patients.
