Excerpt from Diseases of the Skin, a Handbook: For Students and PractitionersOne other point referred to somewhat frequently in this book is the relation of various skin diseases to the vascular system. It has been the custom of some writers to refer the origin of a large number of cutaneous affections to the nervous system, in many cases without the support of a single clinical or pathological fact. On the other hand, the vascular system has been strangely neglected by dermatologists. From various observations the author concludes that abnormal vascular conditions, central or peripheral, lie at the bottom of a great many pathological Skin affections, more especially those of a chronic or recurrent nature. The skin is exposed to incessant traumatism, from which it recovers as a rule, provided the cutaneous circulation be healthy. When the balance Of the cutaneous circulation is disturbed, however, the power of physiological reaction is impaired or lost, and we have a per manent or chronic state of traumatic reaction. In old age, again, we have a marked Shrinkage of the cutaneous capillary circulation. When a similar change takes place prematurely, the skin suffers correspondingly in nutrition and power of resistance to traumatism of various kinds - biological, phy sical, chemical, and mechanical. Premature baldness, from this point of View, spells premature senility, with a shrunken and atrophic scalp.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
