In the early 87th Precinct novels written by Ed McBain, Teddy Carella, the wife of Detective Steve Carella, was referred to as a "deaf-mute," but in later books, McBain stopped using the term. In the foreword to a reprinted edition of "The Con Man", originally published in 1957, McBain says, "A reader pointed out to me two or three years ago that this expression was now considered derogatory. Out the window it went, and Teddy is now speech-and-hearing impaired." == References ==
However, this disease was less mentioned in medical books because it was erroneously considered to be an aesthetic rather than a clinical disorder.Congenital iodine-deficiency syndrome was especially common in areas of southern Europe around the Alps and was often described by ancient Roman writers and depicted by artists. The earliest Alpine mountain climbers sometimes came upon whole villages affected by it. The prevalence of the condition was described from a medical perspective by several travellers and physicians in the late 18th and early 19th centuries. At that time the cause was not known and it was often attributed to "stagnant air" in mountain valleys or "bad water". The proportion of people affected varied markedly throughout southern Europe and even within very small areas, it might be common in one valley and not another. The number of severely affected persons was always a minority, and most persons were only affected to the extent of having a goitre and some degree of reduced cognition and growth. The majority of such cases were still socially functional in their pastoral villages.More mildly affected areas of Europe and North America in the 19th century were referred to as "goitre belts". The degree of iodine deficiency was milder and manifested primarily as thyroid enlargement rather than severe mental and physical impairment. In Switzerland, for example, where soil does not contain a large amount of iodine, cases of congenital iodine deficiency syndrome were very abundant and even considered genetically caused.
