Iodization and thyroid status in relation to stillbirths and congenital anomalies.

Thyroid status is known to have an important bearing on the ability of a woman to conceive, and to bring a normal infant to term. Thyroid status has changed in a number of previously iodine deficient countries as a result of recent iodization programmes. In this study, examination has been made of changes in the rates of two pregnancy outcomes in Tasmania, a State of Australia, namely, stillbirth and infant death due to congenital anomalies. Tasmania began iodine supplementation in 1950. Stillbirth rates declined more rapidly than in Australia as a whole, but show a peak associated with the peak of iodine-induced thyrotoxicosis in 1966. Congenital anomalies causing death show an initial rise in the early 1950s. It is suggested that this is due to persistence of iodine deficiency in the foetus after maternal iodine status improved sufficiently to allow term delivery of a live infant. The later fall coincides with the reaching of reproductive age by the first cohort of Tasmanian women who had been iodine sufficient since childhood, who would therefore not deprive their own foetus of iodine. Examination of trends in New Zealand, Switzerland and Finland, which have each introduced iodization programmes, confirms the largely beneficial effect of iodine supplementation on the rate of infant death due to congenital anomalies.

Time trends in colo-rectal cancer mortality in relation to food and alcohol consumption: United States, United Kingdom, Australia and New Zealand.

Recent epidemiologically and experimental research has implicated dietary factors, including alcoholic drinks, in cancers of the colon and rectum. Analysis of time trends in cancer mortality since 1921, in the United States, England and Wales, Australia, and New Zealand, in relation to changes in per capita consumption of foodstuffs and alcohol reveals some support for the protective effect of fibre, but an inconsistent role for fat and meat in colon cancer. For rectal cancer, and to a lesser extent colon cancer, the most consistent correlate in comparisons across time, and between place, sex, and age-group, is beer consumption. Possible reasons for this correlation within this data set are discussed.

Early psycho-social assessment of overdose patients in a casualty department.

In response to the very large number of patients presenting at the Casualty Department of the Alfred Hospital, Melbouren, following suicidal acts, a Psycho-Social Assessment Clinic employing a crisis intervention model was established in 1970. This communication outlines the structure and functions of the Clinic, describes 100 consecutive new patients seen over a four month period in 1974 and emphasises the benefits to both patients and hospital arising from the operation of such a Clinic.

Use of a community health centre by general practitioners.

The advent of community health centres has brought a change to supportive services in many areas. This situation has produced problems, both for the general practitioner confronted by new expectations and possibilities, and for the health centre seeking his cooperation. There is here an opportunity to observe the process of change in general practice. In the evaluation of a community health centre, GPs in an inner-urban area were interviewed to locate factors related to their use of services. The resulting observations of change in general practice suggested certain conclusions for the health centre's policy.

Mental health problems among university students, and their relationship to academic failure and withdrawal.

Two obvious forms of student "wastage" are academic failure and withdrawal from university. In this prospective cohort study of 2,041 first-year students at Monash University, the relationship of these two events to mental health, university life-stress and other variables is examined. Four factors found to be strongly related to first-year academic failure are mental illness at university a high level of life-stress, poor secondary school academic record, and an extroverted personality. Withdrawal from university during first year is frequently preceded by poor mental health, high life-stress and loneliness. Withdrawal during second year is strongly associated with first-year academic failure and mental illness. The significance of these findings is discussed, and comparisons are made with overseas studies.
