| senile plaque | <neurology> Characteristic feature of the brains of Alzheimer's patients and aged monkeys, consisting of a core of amyloid fibrils surrounded by dystrophic neurites. The principal component of amyloid fibrils in senile plaques is B/A4, a peptide of about 4 kD that is derived from the larger amyloid precursor protein (APP). The B/A4 sequence is located near the C terminus of APP. (18 Nov 1997) |
| senile plaques | Microscopic argyrophilic masses composed of fragmented axon terminals and dendrites surrounding a core of amyloid. They are seen in small amounts in the cerebral cortex of normal elderly people and in larger amounts in those with alzheimer disease. (12 Dec 1998) |
| senile psychosis | Mental disturbance occurring in old age and related to degenerative cerebral processes. (05 Mar 2000) |
| senile retinoschisis | Retinoschisis occurring most often in the elderly and affecting the outer plexiform layer; it begins in the extreme inferotemporal periphery and is not significantly progressive; vision usually is good. (05 Mar 2000) |
| senile sebaceous hyperplasia | Hyperplasia of mature sebaceous glands, forming a nodule on the skin of the face or forehead in elderly persons. (05 Mar 2000) |
| senile tremor | An essential tremor that becomes symptomatic in elderly adults. (05 Mar 2000) |
| senile wart | <dermatology> A skin lesion that is abnormally sensitive to the effects of ultraviolet light (sunlight). Thought to be a precancerous skin lesion that is more common in the fair-skinned or elderly individual. Approximately 20% of these skin lesions will develop into squamous cell carcinoma. Prevention includes the use of sun screen agents and the avoidance of drugs (for example tetracyclines) known to cause photosensitivity reactions. Usually a discreet slightly raised, red or pink lesion located on a sun exposed surface. Texture may appear as rough, gritty or scaly. Growths may be biopsied to look for cancer or removed via cryotherapy or electrical cautery. Some topical agents may be used to promote peeling. (27 Sep 1997) |
| abscess, skin | Medical term for a common boil. (12 Dec 1998) |
| allergy skin test | Test done on the skin to identify the allergy substance (allergen) triggering the allergic reaction. A small amount of the suspected allergy substance is placed on the skin. The skin is then gently scratched through the small drop with a special sterile needle. If the skin reddens and, more importantly, swells, then allergy to that substance is probable. (12 Dec 1998) |
| alligator skin | <dermatology> A group of cutaneous disorders characterised by increased or aberrant keratinisation, resulting in noninflammatory scaling of the skin. Many different metaphors have been used to describe the appearance and texture of the skin in the various types and stages of ichthyosis, for example alligator, collodion, crocodile, fish and porcupine skin. most ichthyoses are genetically determined, while some may be acquired and develop in association with various systemic diseases or be a prominent feature in certain genetic syndromes. The term is commonly used alone to refer to i. Vulgaris. (18 Nov 1997) |
| appendages of skin | The hairs, nails, and sweat, sebaceous, and mammary glands. (05 Mar 2000) |
| aspergillus antigen skin test | <investigation> An antigen, prepared from aspergillus, is injected into the skin. In 48 to 72 hours the site is read as positive or negative. A positive skin test (inflammation at the test site) indicates prior exposure to aspergillus and therefore a risk for developing aspergillosis. (27 Sep 1997) |
| bronzed skin | The dark skin in Addison's disease. (05 Mar 2000) |
| calipers, skin | Calipers are instruments used to measure the diameter of an object. (The word calipers is a corruption of caliber ). The skin fold thickness in several parts of the body can be measured with calipers, a metal or plastic tool similar to a compass. This is done in medicine and physical anthropology. (12 Dec 1998) |
