After an initial chapter describing the latest understanding of laser physics and safety, subsequent chapters consider laser treatment of vascular lesions, laser treatment of pigmented lesions and tattoos, laser removal of unwanted hair, ablative and non-ablative fractional resurfacing, and use of laser treatment for medical purposes. The book is extremely practical and reader friendly. All chapters are very well illustrated, include quick and clear bullet points, and feature a homogeneous structure covering core concepts, currently available technologies, indications and contraindications, an example of a consent form, and the author’s personal treatment approaches. The authors are without exception world experts in the field from North America or Europe.Trade ReviewFrom the reviews of the second edition:“The purpose is to provide an updated overview of currently available lasers to treat various skin conditions … . The audience is dermatologists. … Dermatologists contemplating the purchase of a laser would find this book useful. … I recommend this as a good clinical introduction to understanding how lasers work and the considerations that must be taken into account when choosing a particular laser modality for a particular condition.” (Patricia Wong, Doody’s Book Reviews, July, 2013)Table of ContentsLaser Physics and Safety.- Laser Treatment of Vascular Lesions.- Laser Treatment of Pigmented Lesions.- Laser Hair.- Ablative and Non-ablative Fractional Resurfacing.- Laser Treatment of Medical.

Book SynopsisTherapeutic breakthroughs in medicine are usually accompanied by a wealth of data. Often they result in a change of disease treatment paradigms. Tacrolimus ointment is the first in the new class of steroid-free Topical Immunomodulators (TIMs), and as such represents the first true breakthrough since the introduction of topical steroids more than 50 years ago for the treatment of T-cell mediated inflammatory skin diseases such as atopic dermatitis. This book gives an easy-to-read overview of the discovery and the development of Tacrolimus ointment for the treatment of atopic dermatitis. Summarising the largest clinical trial program ever conducted in dermatology for a new treatment with more than 13000 patients, it offers a detailed insight into the efficacy and safety profile of Tacrolimus ointment. Based on this large body of data and extensive personal experience, the authors offer practical and hands-on guidance for the physician as to when and how to use Tacrolimus ointment in daily practice.Table of ContentsAtopic Dermatitis I.- 1 Epidemiology of Atopic Dermatitis.- 2 The Pathogenesis of the Atopic Eczema/Dermatitis Syndrome.- 3 Detecting, Diagnosing and Grading Atopic Dermatitis.- 4 Current Treatment of Atopic Dermatitis.- Development of Tacrolimus Ointment II.- 5 Development of Tacrolimus Ointment.- 6 Pharmacokinetics of Tacrolimus Ointment: Clinical Relevance.- 7 Tacrolimus as an Immunomodulator.- III Clinical Experience with Tacrolimus Ointment in Atopic Dermatitis.- 8 Clinical Experience in Adults.- 9 Clinical Experience in Children.- 10 The Role of Tacrolimus Ointment in Atopic Dermatitis.- 11 Other Potential Dermatological Indications for Tacrolimus.- IV Social Impact of Atopic Dermatitis.- 12 Quality of Life Measurements in Atopic Dermatitis.- 13 Pharmacoeconomics in Atopic Dermatitis.- Appendix V.
