Glossary 95 Index 105 v intr Oduction Many people throughout the world are living well into their old age. A person’s physical, as well as psychological, well being is directly affected by his or her general health and the health of his or her skin. Most of us have at least one, if not three or four, skin conditions that can be treated or at least improved with good advice and action. The skin is a magnificent organ. If you could look quite closely at each square inch of skin, you would find about 19 million cells, 90 oil glands, 600 sweat glands, 65 hairs, and tens of millions of microscopic bacteria, and each square inch is nourished and kept active by 19,000 nerve cells and 19 feet of miniscule blood vessels. All of this amazing collection helps to eliminate one third of the body’s waste products and toxins, regulates and maintains water balance and body temperature, uses touch receptors to help us sense pain and avoid harm, and forms a barrier to protect us from outside damage. Clearly, you need to keep this marvelous organ at its best. More today than ever before, the aesthetic function of our skin has taken the forefront in modern media and our own perceptions. The multibillion- dollar cosmetic industry has brought in wave after wave of new techniques and products and has filled our offices, magazines, and televisions with the promise of a forever youthful glow. This is an uphill battle, however, unless you have the right advice that can cut through the avalanche of information, keep up with the advancements, and capture and use what is important to you and your skin type. Although the constant turnover of skin cells allows for renewal and repair, the skin also keeps its own diary, and the cumulative changes show as we age. I see many different skin conditions in the older person, whether they’re in a nursing home or in my office, and I believe that not enough attention is given to skin problems as we age. A delay in recognition leads to a delay in care of those problems. Also, in many areas, there is little access to specialists. 100 Q&A ABOUT AGING SKIN Albert M. Kligman, MD, PhD (inventor of Retin-A®), wrote, “This tradi- tional neglect of the skin is well-nigh unforgivable and has cruel consequences for the well being of the elderly. These diseases do not kill but they are per- sistent pestilences which spoil the quality of life. It is the skin more than any other organ which most clearly reveals the cumulative losses which time prints on the visage of the high and low alike.” Dr.

It is usually secondary to carcinoma of some other organ, often the breast. It may occur in the form of multiple shot-like (lenticular) masses, in which ulceration freąuently develops or as a diffuse carcinomatosis (cancer en cuirasse), in which the skin is hard and immovable. Another form of rare occurrence is when a carcinomatous change is dependent upon some precancerous state or when, as in Fig.

  • Skin Deep: the Integumentary System and Botanical Medicine
    Applied Phytotherapeutics I Skin Deep By Terry Willard ClH, PhD; Todd Caldecott ClH Lesson 7 – Integumentary System Skin Deep: The Integumentary System and Botanical Medicine Introduction The Skin is the largest organ in the body and takes up considerable attention by many people. Our skin is the interface between the internal structures of our body and environments. It is also an interface between our consciousness and the world, through expression, and adornments. The psychological relationship a person has with their skin can be quite complex. It is often wrapped up in ones own self-image. When we refer to the skin, we are referring to a group of tissues that make up the integumentary system. Of all the body organs, none is more easily assessed in a clinical environment than the skin. The skin is derived from the embryonic ectoderm, as is the nervous system, and thus many skin conditions are partially influenced by the underlying state of the nervous system. In Ayurvedic medicine skin relates to the sensation of touch (sparsha) and the element of wind (vayu), the latter of which forms the humoral division of vata, which functions to control the nervous system. Thus the correlation between the skin and the nervous system in Ayurvedic medicine bears remarkable similarity to the scientific concept that the skin and nervous tissue are similar tissues. In the formation and ongoing regeneration of skin however, Ayurvedic medicine considers the skin to be derived from blood, in much the same that milk when heated forms a scum on its surface. Blood is primarily a nutrient delivery and waste removal system, and is routed through the spleen and liver to be filtered.
