Essential medical facts on over 2,000 genetic syndromes. Organized alphabetically, this book provides comprehensive medical coverage for each syndrome, from genetic basis to manifestations to related medical considerations.

This book provides a guide to the diagnosis and management of pigmentary disorders. Each chapter explores a different clinical case to give the reader an interdisciplinary understanding of treatment options. Particular attention is given to the treatment of hypopigmentation, hypomelanosis and discoloration with cases highlighting the effects of drug intake, genetic alterations and the polluted environment. Clinical Cases in Pigmentary Disorders examines therapeutic approaches through evidence-based best practice techniques and is relevant to dermatologists, oncologists, pharmacologists and pathologists.

Leukoderma is a generic term for any pigmentary dilution, be it congenital or acquired, circumscribed or generalized, devoid of or partially lacking in pig mentation. In the approach to the diagnosis of leukoderma, we have generally first considered the age of onset, whether leukoderma was congenital or ac quired, the extent and pattern of involvement, and the degree of pigmentary dilution. The organization of this monograph reflects this approach. For ex ample, we have separated the section devoted to various disease entities into diffuse and circumscribed leukoderma and the latter into various etiologies such as genetic, metabolic, infectious, and endocrinologic. One of several justifications for this monograph is to present an approach to the diagnosis of leukoderma, as detailed in Part II. In formulating a guide for the physician, we have found some limitations to our previous approach; we therefore offer the following new classification based upon a clini cal-pathologic correlation. This could provide the means to describe both the clinical and pathologic findings in one term.

This 1999 edition of The Neural Crest contains comprehensive information about the neural crest, a structure unique to the vertebrate embryo, which has only a transient existence in early embryonic life. The ontogeny of the neural crest embodies the most important issues in developmental biology, as the neural crest is considered to have played a crucial role in evolution of the vertebrate phylum. Data that analyse neural crest ontogeny in murine and zebrafish embryos have been included in this revision. This revised edition also takes advantage of recent advances in our understanding of markers of neural crest cell subpopulations, and a full chapter is now devoted to cell lineage analysis. The major research breakthrough since the first edition has been the introduction of molecular biology to neural crest research, enabling an elucidation of many molecular mechanisms of neural crest development. This book is essential reading for students and researchers in developmental biology, cell biology, and neuroscience.

Heredity, either alone or in combination with environmental factors, is the most prominent underlying cause of hearing impairment. Thanks in large part to positional cloning techniques, scientists have identified nearly 100 gene loci implicated in hearing loss since 1995-an extraordinarily rapid rate of gene identification. Genetic Hearing Loss branches into syndromic and nonsyndromic categorical directions in its coverage of the genetics behind hearing loss. Authored by 60 internationally recognized researchers, the book describes the normal development of the ear, updates the classification and epidemiology of hearing loss, and surveys the usage of audiometric tests and diagnostic medical examinations.
