| 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) |
| acute interstitial pneumonia | A severe and usually fatal form of pneumonia occurring primarily in infants usually considered a form of hypersensitivity pneumonitis. (05 Mar 2000) |
| alcoholic pneumonia | Pneumonia occurring in patient with alcoholism, usually after a period of intoxication with stupor, resulting in aspiration. (05 Mar 2000) |
| anthrax pneumonia | A form of anthrax acquired by inhalation of dust containing Bacillus anthracis; there is an initial chill followed by pain in the back and legs, rapid respiration, dyspnea, cough, fever, rapid pulse, and extreme cardiovascular collapse. Synonym: anthrax pneumonia, ragpicker's disease, ragsorter's disease, rag-sorter's disease, wool-sorter's pneumonia, woolsorter's disease, wool-sorter's disease. (05 Mar 2000) |
| apex pneumonia | Apical pneumonia, pneumonia of the apex or apices. (05 Mar 2000) |
| aspiration pneumonia | <chest medicine> Refers to the inappropriate passage of food, water, stomach acid, vomit or another foreign material into the lungs. Aspiration, particularly involving gastric acid, will often result in a serious pneumonia. (27 Sep 1997) |
| atypical pneumonia | <chest medicine> This refers to a type of pneumonia that does not follow the typical signs and symptoms of pneumonia. A number of different viral and bacterial agents have been identified which can cause this form of respiratory infection. Examples include Chlamydia pneumonia, psittacosis, Mycoplasma, influenza A or B, adenovirus and Legionella. Antibiotics will be necessary in all but the mildest cases. Symptoms generally improve in less than 2 weeks. (27 Sep 1997) |
| bacterial pneumonia | Infection of the lung with any of a large variety of bacteria, especially Streptococcus pneumoniae(pneumococcus). (05 Mar 2000) |
