The results of two 5-year studies, for 1974-78 and 1984-88, of cutaneous malignant melanoma (CMM) in Northern Ireland show changes in the presentation of the disease. Although there is some evidence of earlier diagnosis, the rise in incidence has produced an overall increase in the number of cases with advanced disease.

Multicenter StudyFamily anxiety in advanced cancer: a multicentre prospective study in Ireland.
Six home care services in Southern Ireland collected data on a total of 757 patients over a 6-month period. Patient and family well-being were measured using the staff-rated Support Team Assessment Schedule and Karnofsky Index. Five hundred and eight patients died while in care, 75% of whom died at home. ⋯ Discriminant analysis produced two predictive models. In model 1, family anxiety at referral strongly predicts family anxiety in the last week of life. In model 2, family anxiety at referral is excluded from the analysis, and the significant predictor factors at referral for family anxiety in the last 4 weeks of life are patient symptom control, sex of patient, diagnosis and patient age.

A prospective study of endogenous serum hormone concentrations and breast cancer risk in post-menopausal women on the island of Guernsey.
The associations between serum concentrations of oestradiol, testosterone and sex hormone-binding globulin (SHBG) and risk of breast cancer in post-menopausal women were investigated in a prospective study on the island of Guernsey. Sixty-one women who developed breast cancer an average of 7.8 years after blood collection were matched for age, year of blood collection and number of years post-menopausal with 179 control subjects. Women using exogenous hormones at the time of blood collection were excluded from the study. ⋯ Adjusting for testosterone and SHBG concentrations did not substantially alter the odds ratio for oestradiol. Although testosterone and SHBG concentrations were associated with breast cancer risk, the concentrations of these hormones were correlated with those of oestradiol; the associations were not statistically significant after adjusting for oestradiol concentration. These data provide evidence that serum oestradiol concentrations in post-menopausal women may have a substantial effect on breast cancer risk.

High-contact paternal occupations, infection and childhood leukaemia: five studies of unusual population-mixing of adults.
The hypothesis has been tested that, among excesses of childhood leukaemia associated with extreme population-mixing, the incidence is higher for the children of men in occupations involving contact with many individuals (particularly children), as noted in certain childhood infections. Data on childhood leukaemia were examined from five previous studies of the author in which significant excesses had been found associated with population-mixing involving adults. Occupational titles were categorized according to the estimated level of work contacts as medium, high, very high or indeterminate. ⋯ The excess in the high category was mainly because of paternal occupations connected with the construction industry and transport, suggesting a broader definition of the 'very high' contact category. No sign of these excesses was found in a limited examination of the question outside areas of population-mixing using mortality data for childhood leukaemia in the general population of England and Wales. The findings represent the first individual-based support for infection underlying childhood leukaemia that is promoted by population-mixing, as well as further support for the role of adults in transmission of the infection.
