The polyp story B . C . MORSON

چکیده
'Clear and precise definitions of diseases, and the application of such names to them as are expressive of their true and real nature, are of more consequence than they are generally imagined to be: untrue or imperfect ones occasion false ideas; and false ideas are generally followed by erroneous practice.' Sir Percival Pott, 1765, in a treatise on fistula-in-ano Introduction The little word 'polyp' has probably caused as much confusion as any other commonly used in modem medical nomenclature. Indeed, it has been used with such diverse meaning as to create barriers of misunderstanding which in turn have adversely affected the care of patients. Precision in the use of words, without being pedantic, is clearly desirable but attempts to reach general agreement about how the meaning of a word (and its synonyms) is to be conveyed can be fraught with controversy. That august body, the World Health Organization, among others, has spent large sums of money arranging for experts from all over the world to gather together for discussions on the nomenclature and classification of disease which, in the experience of this writer, can be somewhat acrimonious and consensus of opinion may be difficult or impossible to achieve. The end result is more likely to be a reflection of majority opinion rather than universal agreement. The 'polyp story' is a good example of how one word used with different meaning can create such confusion and misunderstanding that meaningful communication between its users may breakdown. What is a polyp? Sir John Bland-Sutton, one of the great Surgeon-Pathologists of the early 20th Century, was among the first to emphasize that the word polyp had no place in tissue (histological) diagnosis. He pointed out that 'the ancient name polypus applied to benign tumours attached to mucous membrane by means of a stalk has merely a clinical value' (Bland-Sutton, 1922). But he also made a clear

Juvenile polyposis coli.
The term 'polyposis coli' applies to a condition of multiple polyps of the large intestine and is used synonymously with 'familial polyposis' and 'multiple adenomatosis'. The latter name emphasizes the fact that the individual polyps of this disease in no way differ from adenomas observed as solitary lesions. The object of this paper is to describe the histopathology, clinical features, and fam...

متن کاملSiesmic Assessment og Ductility and Strength Capacities of Low-Rise R. C. Buildings
This paper presents a methodology for the assessment of ductility and strength capacities in low-rise buildings. This method utilizes the characteristics of force-displacement for the lowest story level or considers the weakest story in any given low-rise building for its primary analysis. Calculations are based on two levels of earthquake motions, namely strong earthquakes (PGA=0.3 g), and ver...
