Evaluation of argon laser surgery in children under 13 years of age.

Argon laser surgery is an effective treatment for ectasias and congenital port-wine stains; however, its use in children under the age of 13 is controversial. This paper reviews 202 children under the age of 13 who underwent argon laser treatments for congenital port-wine stains, spider angiomas, epidermal nevi, and lentigines. The clinical characteristics of port-wine stains in 170 children are discussed. Good to excellent results (moderate to complete clearing) in port-wine stains were obtained in 60 percent of patients and seemed to correlate best with lack of blanchability on pressure. Hypertrophic scarring was seen in only 7 children, all of whom had undressed wounds; no significant scarring has been seen in any subsequent child who had maintained a dressed wound postoperatively.

Another seventeenth-century denigration of Gaspare Tagliacozzi.

Gaspare Tagliacozzi published his carefully documented procedures for nasal reconstruction at the end of the sixteenth century. However, almost all authorities in the succeeding century failed to give him credence. Although his name was widely known, his work became an object of scorn. James Cooke, author of one of the most popular English surgical textbooks of the seventeenth century, in an amusing and previously unnoted reference, adds to this denigration and helps to explain why nasal reconstruction became a subject of satire in England.

Aggressive histological features of keratoacanthoma.

Thirty-nine keratoacanthomas from 35 patients have been studied, six of which showed perineural, and one vascular, invasion. Thus far, their aggressive histological behavior has not been paralleled by a similar clinical course. However, continued close follow-up is essential.

The increasing incidence of melanoma.

A study of our hospital records has confirmed a striking increase in the number of melanoma cases. An examination of the New York State statistics demonstrates a 202 percent increase in the case rate from 1950 to 1971. The Connecticut statistics extending from 1935 to 1972 show an age-adjusted incidence rate increase of more than 300 percent for men, and more than 600 percent for women. An increased frequency of melanoma has been reported also for Texas, Canada, Australia, England and Wales. The available information on melanoma deaths and mortality rates fails to suggest that these lesions are biologically less significant than those so designated in the past. There has been no change in preferential sites of melanoma location in either sex, despite the increased incidence of the disease reported from these many geographic areas. The cause of the increased incidence remains obscure.
