Money facilitates the exchange of goods and services; it is used to pay for various obligations (salaries, taxes, rents…), as a unit of measurement, to put a price on things, and as a way of accumulating wealth. Of all the things that have been used as money, metal, and especially noble metals, has been the most widely used medium because of its virtues of conservation and rarity. Among the noble metals, silver has been the most widely used, and in this article I review the role of silver in the history of money.
Specific factors which have an influence on the average length of stay in the otolaryngology unit... more Specific factors which have an influence on the average length of stay in the otolaryngology unit of a University Hospital are studied; the patients are covered by some type of insurance and have no out-of-pocket expenses. The effect of the following variables on the average length of stay is evaluated: age, sex and type of pathology. The periods of hospitalisation are significantly longer (Mann-Whitney test) in males (p < 0.0001), in older patients (p < 0.008) and in the case of tumours, which prolong the period of stay especially of males (p < 0.0001). It is suggested that the shorter stay in the case of females may be conditioned by social and family factors.
