This book focuses on helping both dermatologists and non-dermatologists approach the treatment of each disease in a pragmatic manner. Each chapter reviews the current literature of treatments for each disease, rating disease severity, and provides pragmatic guidelines based on disease severity on the usage of available medications. The current literature does not provide effective guidelines. This book addresses this deficiency. This book will help guide clinicians in implementing appropriate treatments based on the specific disease and its severity, and possible alternatives in an algorithmic format. It will make the management of these diseases more pragmatic based on both the literature and clinical experience of experts.
