Softcover reprint of the hardcover lst edition 1976 ISBN 978-3-642-51622-1 ISBN 978-3-642-51620-7 (eBook) DOI 10.1007/978-3-642-51620-7 Preface The skin on the fingertips and palmar and plantar surfaces of man is not smooth. It is grooved by curious ridges, which form a variety of configurations. These ridge configurations have attracted the at tention of laymen for millenia. They have also evoked the serious interest of scientists for more than three centuries. The anatomist Bidloo provided a description of ridge detail in the seventeenth cen tury. Since then, additional information has been added by anthro pologists, biologists, and geneticists. For the last century, the fact that each individual's ridge configurations are unique has been uti lized as a means of personal identification especially by law enforce ment officials. Widespread medical interest in epidermal ridges de veloped only in the last several decades when it became apparent that many patients with chromosomal aberrations had unusual ridge formations. Inspection of skin ridges, therefore, promised to provide a simple, inexpensive means for determining whether a given patient had a particular chromosomal defect. However, the promise was only partially fulfilled because of the inherent variability of skin ridge configurations. It was possible to draw conclusions about ridge ab normalities in groups of patients but not always in a given individual. Patients and clinicians became somewhat disenchanted with the clinical value of studying ridges. Nonetheless, considerable clinically useful information about groups of individuals with chromosomal defects has been discovered and therefore a knowledge of the types of deviations associated with various medical disorders can add ap preciably to the diagnostic armamentarium of the clinician. Unusual v PREFACE ridge configurations have been shown to exist not only in patients with chromosomal defects but also in patients with single-gene dis orders and in some in whom the genetic basis of the disorder is unclear. More than 30 years ago, a monograph on epidermal ridges was published by Cummins and Midlo (1943/1961). This classic pro vided interesting information on the historical development of the scientific study of epidermal ridges and invaluable advice on how to record and analyze epidermal ridge configurations. Cummins and = Midlo (1926) also coined the name dermatoglyphics (derma skin; glyphics = carvings) for the scientific study of ridges as well as the ridges themselves. This label has now gained universal accept ance. They also included some information on a number of medical disorders. However, their work precedes the burgeoning of cyto genetics that has occurred in the last several years and, therefore, the recent work on dermatoglyphics in medical disorders is not included in their monograph. Although several works on dermatoglyphics have appeared since publication of the Cummins and Midlo classic, none has treated the subject comprehensively. The present monograph attempts to fill this gap. It aims to pro vide an illustrated guide to ridge analysis and also to bring together the widely scattered recent and older information on dermatoglyphic studies in medical disorders. The practicing physician may find much of value in this book that he can apply in his day-to-day work. At the same time, there are sufficient data to provide a reference re source to the medical research worker. Because genetic and anthro pologic aspects of dermatoglyphics are dealt with adequately in other recent publications (Cummins and Midlo, 1943/1961; Martin and Saller, 1962; Holt, 1968; Loeffler, 1969), they are not discussed in any great detail in this book. Only sufficient information is given on the latter topics to provide a foundation to the serious medical investi gator. The first part of the book gives information on how to record dermatoglyphics. The second part provides instruction in derma toglyphic interpretation, concentrating on aspects that have medical relevance. The third part provides up-to-date summaries of infor mation on dermatoglyphics in a variety of medical disorders. A sec tion is also included on palmar and finger creases, although, strictly speaking, analysis of creases is outside the pale of dermatoglyphics. The medical disorders discussed are a selected rather than an ex haustive list because isolated case reports and questionable analyses of some medical disorders have been excluded. Only well-substan tiated data are included. The information has been collected from both the English and the non-English literature so that dermato- vi PREFACE glyphic data that may not have been readily available heretofore are opened to a wider audience. For readers who require only summary data, tables with the salient conclusions are provided; for those' who require more information, the text should prove useful.

The resulting ridge configurations are genetically determined and in fluenced (or modified) by environmental forces. There is a paucity of knowledge concerning the developmental mechanism that deter mines ultimate epidermal ridge patterns but a relationship to the fetal volar pads clearly exists because ridge patterns form at the sites of these pads. Fe.tal volar pads (Figure 1.1) are mound-shaped elevations of mesenchymal tissue situated above the proximal end of the most dis tal metacarpal bone on each finger, in each interdigital area, in the thenar and hypothenar areas of the palms and soles, and in the calcar area of the sole. Secondary fetal pads may be found in other areas, such as on the central palm or as pairs on the proximal phalanges (Mulvihill and Smith, 1969). The formation of these pads is first visible on the fingertips in the sixth to seventh week of embryonic development. The pads become very prominent during the subse quent several weeks, diminish again in the fifth month, and disappear completely in the sixth month. Within this period the ·dermal ridges coalesce into specific patterns, replacing the volar pads. It is believed that the presence of the volar pads as well as their size and position are, to a large extent, responsible for the configuration of papillary ridge patterns, as postulated by Bonnevie (1924). For example, small pads would result in a simple pattern (arch), whereas more promi nent pads would tend to lead to the devl,'(lopment of large and more complex systems of ridge configurations (loops and whorls).
