“…The study comprised more than 4% of the patients with skin cancer in each city, based on the estimated prevalences of NMSC for each region and the estimated populations (Giles et al, 1988;Silverstone and Gordon, 1966;Stenbeck et al, 1990). The study relied on the patients referred for treatment and this could have caused a bias in the sample.…”

The clinical features of patients with basal-cell carcinoma (BCC) living in temperate and tropical Australia were studied. In the temperate zone the patients were considerably older on average, men outnumbered women and there were differences between the sexes in the site of the prevalent BCC. In the tropics the patients were significantly younger on average, the male-to-female ratio approached unity and there were no differences between the sexes with regard to the site of the BCC.

“…In the United States the incidence of neonatal infection due to this organism has been estimated at two to three cases per 1000 live births,' whereas in the United Kingdom it has been reported as being about one tenth of this (2-9/10000).2 Mortality from neonatal septicaemia caused by group B streptococci is between 20% and 50%.3 Since 1980 we have regularly monitored the respiratory rate of newborn babies as an increased rate is a frequent early sign of infection. 3 We assessed the effect of monitoring on the mortality of neonates from septicaemia due to group B streptococci.…”

“…There have been few epidemiological studies of these lesions at a community level and there has never been a population wide survey of their incidence in Australia, which purportedly has the highest rates of skin cancer in the world. [1][2][3][4][5] Because of the heightened risk to Australians, most of whom are of European origin (Aborigines account for only about 1% of the population), education campaigns have been carried out to try to decrease skin cancer by promoting behavioural changes with respect to exposure to the sun. Without routine monitoring of non-melanocytic skin cancer in the community the only evaluation of these programmes has been by assessment of behavioural end points.…”

In 1985, as part of a national random household omnibus survey by a market research company, 30976 Australians (mostly of European origin) were asked whether they had ever been treated by a doctor for skin cancer. The treating doctor or hospital was then approached for confirmation of the diagnosis of ali those, people who claimed to have been so treated within the past 12 months. Demographic data were also collected, permitting analysis by age, sex, country of birth, current residence, and skin reaction to strong sunlight.Melanomas accounted for less than 5% ofthe tumours treated. The world standardised incidence of melanoma was 19/100 000 population. The standardised incidence of treated nonmelanocytic skin cancer in Australia was estimated to be 823/100 000. The standardised rates for basal celi carcinoma and squamous cell carcinoma were 657 'and 166/100 000 respectively, yielding a standardised rate ratio of about 4:1. Standardised rates based on medically confirmed cases only were 555, 443, and 112/100 000 for all non-melanocytic skin cancers, basal celi carcinomas, and squamous cell carcinomas respectively. Significant differences and trends in incidence were noted with respect to age and sex. Rates in men were higher than those in women but significantly so only after the age of 60. People born in Australia had a rate of 936/100 000 compared with 402/100 000 in British migrants. Rates for non-melanocytic skin cancer showed a gradient with respect to latitude within Australia. The rate in people residing north of 29°S was 1242/100 000 compared with a rate of 489/100 000 in those living south of 37°S. A person's skin reaction to strong sunlight was a good indicator of the risk of skin cancer, tanning ability being inversely related to its incidence. The rate in those who always burnt and never tanned when exposed to strong sunlight was 1764/100 000 compared with a rate of 616/100 000 in those who always tanned and never burnt. These findings have important implications for public education programmes in relation to exposure to sunlight in Australia.Introduction Non-melanocytic skin cancers are common in many parts of the world but accurate reports of their frequency are rare. Non-melanocytic skin cancer presents difficulties for cancer registration as many cases are treated in doctors' surgeries by simple excision, curettage, or cryosurgery. Cancer registries that record non-melanocytic skin cancer depend entirely on that variable proportion of tumours that are histologically verified and then notified. There have been few epidemiological studies of these lesions at a community level and there has never been a population wide survey of their incidence in Australia, which purportedly has the highest rates of skin cancer in the world.

An analysis Is presented of a referred series of 1411 basal cell carcinomas treated by surgical excision and plastic surgical repair In which 259 were recurrent after previous other treatments. Of the 1,411 BCCs treated there were 10 BCCs which recurred (0.7% recurrence rate). A further 10 BCCs were primarily re‐excised because of Inadequate clearance around the tumour found on histological examination. (0.7% primary re‐exclslon.) The cases recurrent after previous treatment did not behave badly In terms of subsequent recurrence as they were widely excised and carefully observed In the postoperative years. Surgery must aim to be curative. We clearly define the tumour margin using magnification and mark an adequate clearance of surrounding normal tissue. This Is then excised In width and depth. Repair of the defect Is carried out to restore the area to as near normal as possible. Surgical repair Is able to bring new tissue Into the area to further enable it to withstand the rigours of the climate and not leave behind a premallgnant scarred area.
