Dermatological diseases are extremely common around the globe, and a systematic understanding of these conditions and their relationships with various epidemiological factors could provide insights to help governments and private institutions address the challenges they need to overcome in order to improve global health. This extensively revised second edition comprehensively discusses the fundamental areas of dermatological practice in public health. It features more than 900 figures, eight new chapters and two new sections: a) Dermatological Biopsy and Major Histopathological Patterns, exploring surgical methods for collecting cutaneous specimens from outpatients and the analysis of major histopathological patterns; b) Special Chapters, which outlines Hospital Dermatology in Public Health, covering hospital care as a backup in dermatoses of importance in public health; Dermatological Education in Public Health, examining the interface between teaching and students for the development of dermatological practice; and a Brief History of Dermatology. Further topics include the profile of dermatological care based on epidemiological concepts; the most significant skin diseases (including dermatology in tropical medicine); the relationship between the environment and dermatological diseases; dermatoses in the human life cycles, diseases that are not primarily dermatological, but have a high impact on public health and may have skin and mucosal manifestations; a number of emerging issues in dermatology in public health; clinical approaches (diagnosis and management) to common dermatological symptoms; multidisciplinary approaches in dermatology; surgical and histopathological aspects of the main dermatological diseases; and the hospital as an aid in the management of complex dermatoses and dermatological education in public health. Written by experts with extensive experience in their respective fields, this book is a valuable reference resource for undergraduate and graduate students, dermatologists and general practitioners, as well as anyone interested in the relationship between dermatology and public health.
