Cancer incidence among migrant populations in South Australia.

South Australian Cancer Registry data for 1977-1986 have been used to compare the incidence of cancer for overseas-born populations and for the State as a whole. British and Irish migrants were found to have a higher incidence of all cancer sites combined, largely because of elevations in the incidence of cancers of the lung, stomach and female breast, whereas southern-European migrants showed a lower incidence of cancer, mostly as a result of low incidence rates for cancers of the colon, prostate, lung (women only), melanoma and female breast. Differences in incidence also were evident by country of birth for cancers of the buccal cavity, oropharynx, nasopharynx, oesophagus, liver, larynx, pleura, testes, uterine body, bladder and kidney, and various lymphohaematopoietic cancers. The aetiological implications of these findings, particularly in relation to environmental and life-style factors, are considered.

Bone allograft banking in South Australia.

The South Australian Bone Bank had expanded to meet an increased demand for allograft bone. During a 5 year period from 1988 to 1992, 2361 allografts were harvested from 2146 living donors and 30 cadaveric donors. The allografts were screened by contemporary banking techniques which include a social history, donor serum tests for HIV-1, HIV-2, hepatitis B and C, syphilis serology, graft microbiology and histology. Grafts were irradiated with 25 kGy. The majority of grafts were used for arthroplasty or spinal surgery and 99 were used for tumour reconstruction. Of the donated grafts 336 were rejected by the bank. One donor was HIV-positive and two had false positive screens. There were seven donors with positive serology for hepatitis B, eight for hepatitis C and nine for syphilis. Twenty-seven grafts had positive cultures. Bone transplantation is the most frequent non-haematogenous allograft in South Australia and probably nationally. The low incidence of infectious viral disease in the donor population combined with an aggressive discard policy has ensured relative safety of the grafts. The frequency of graft rejection was similar to other bone banks but the incidence of HIV was lower.

Hybridization between tammar wallaby (Macropus eugenii) populations from Western and South Australia.

Populations of tammar wallabies (Macropus eugenii) occur in southwest Western Australia and on five Australian offshore islands, four in Western Australia and one in South Australia. The South Australia and Western Australia populations have probably been isolated from each other for 50,000-100,000 years. Studies have shown that there are morphological and genetic differences between these populations. Attempts at mating individuals from Garden Island (Western Australia) with individuals from Kangaroo Island (South Australia) indicate that while the two populations can hybridize in captivity and F1 hybrids of both sexes are fertile, a barrier to successful reproduction between these two populations is in the initial stages of development.

Obstetric epidural services in rural South Australia.

A survey of sixty South Australian country hospitals found that 35 units had more than 25 deliveries per year (total deliveries 4,247, which is 21.5% of total live births in South Australia during 1989). Twenty-five of these units had an epidural service (71%) and the overall epidural rate was 16.7%, 9.5% provided by general practitioner anaesthetists and 7.2% by specialists. General practitioner anaesthetists were involved more in the medium-sized units (50-200 deliveries per year), whereas specialists provided more services in the larger regional units and the small units as visitors. The epidural rate varied between 6-20% depending on the size of the unit. Most country regions in South Australia have reasonable access to an epidural service. The more geographically isolated areas are being serviced by general practitioner anaesthetists.

Effects of challenge with trichostrongylid nematode larvae on immunologically resistant grazing yearling sheep in South Australia.

Paddocks near Gawler, South Australia, were grazed by newly weaned sheep which received either no anthelmintic treatment, regular 3-weekly treatment or a single treatment in February. A decline in the faecal egg count of untreated sheep in autumn associated with the ingestion of infective larvae indicated that the sheep had developed a resistance to reinfection. At the end of the experiment, 10 sheep were experimentally infected with Trichostrongylus vitrinus larvae to demonstrate this resistance. Untreated sheep grew less wool and had lower body weights when compared with treated animals and were extremely 'daggy'. A single treatment in February did not prevent production losses or scouring.

Teenage pregnancy: trends, characteristics and outcomes in South Australia and Australia.

OBJECTIVES: To describe trends in teenage pregnancy rates in South Australia and Australia in 1970-2000, and the socio-demographic and clinical characteristics and outcomes of teenage women who gave birth in South Australia in 1995-99. METHODS: A descriptive study using population-based legislated South Australian perinatal and abortion data, Australian Medicare and hospital morbidity data on abortions, and birth registration rates from the Australian Bureau of Statistics. RESULTS: The teenage pregnancy rate in South Australia fell in the 1970s and 1980s, increased in the 1990s, but is declining at the turn of the century. Teenage abortions exceeded livebirths annually from 1994, and in 2000 the teenage abortion, birth and pregnancy rates were 22.4,18.3 and 40.8 per 1,000 respectively. The Australian rates, which are an underestimate, follow the South Australian trends and are declining but still much higher than in many western European countries. High socio-economic areas in South Australia have the lowest teenage pregnancy rates but the highest proportion of teenage pregnancies terminated. Teenagers who gave birth were more likely than older women to be Australian-born, Aboriginal, smokers during pregnancy (47% vs. 23%), to attend few antenatal visits, and to have preterm, small-for-gestational-age and low birthweight babies and neonatal deaths. Perinatal mortality has halved among teenagers under 17 years in the past decade. CONCLUSIONS AND IMPLICATIONS: Births to South Australian teenage women are associated with social disadvantage and relatively poor perinatal outcomes, although these have improved. Current strategies are aimed at reducing the incidence of unplanned teenage pregnancy and improving support for pregnant teenagers.

Newborn screening in South Australia: is it universal?

OBJECTIVE: To determine the biochemical screening rate of newborns in South Australia and the factors associated with babies not being screened. DESIGN: Matching of data in the SA Newborn Screening Centre database (acquired from Guthrie cards) with the SA perinatal data collection (compiled from supplementary birth records) to determine how many newborns missed screening. Risk factors for missed screening were identified from sociodemographic and clinical variables recorded in the perinatal data collection and analysed by multivariable unconditional logistic regression analysis. PATIENTS AND SETTING: All live births (n = 18,426) in South Australia in 1999, in the 63 hospitals assisting deliveries or in the home. MAIN OUTCOME MEASURES: Rates of biochemical screening and missed screening in all newborns and among various subgroups; adjusted odds ratios (after multivariable logistic regression analysis) for risk factors for missed screening. RESULTS: The newborn screening rate in South Australia in 1999 was 97.8%. Babies born at home, born to an Aboriginal mother, or born to a mother who normally resided in another state were at higher risk of missed screening. Other factors associated with missed screening were having fewer than seven antenatal visits, prematurity (gestational age at birth < 32 weeks), congenital abnormality in the baby, use of paediatric intensive care, early discharge from hospital before 3 days (but especially after less than 1 day), and death of the baby during the neonatal period. CONCLUSION: In South Australia, while 2.2% of all newborns missed screening in 1999, in certain high-risk groups the proportions of unscreened babies were significantly higher. With a 2% missed screening rate, one might expect one newborn with a screening-detectable disorder to elude detection every other year in South Australia.

Demographic response to rural restructuring and counterurbanisation in South Australia, 1981-1991.

"Using South Australia as a case study, this paper seeks to trace and demonstrate two processes (counterurbanisation and rural restructuring) whose effects overlap to differentiate and characterise the population geography of...two zones, separated by a transition along the outer fringe of Adelaide's urban field.... In the demographic core zone [rural restructuring] has been partly offset by continued counterurbanisation, resulting in demographic mixing and rural dilution. The 1981-91 population growth in rural communities is shown to be more a function of population density at the outset of the period than of initial population size. Demographic growth...is shown to conform to a simple unidimensional scale, allowing the production of a clear, easily interpretable typology of rural demographic change with few non-conforming statistical areas. At a local level within individual rural communities, demographic decline is shown to be accompanied by increased concentration of the population into small towns, while demographic growth is associated with deconcentration."

The effects of partial decriminalisation on cannabis use in South Australia, 1985 to 1993.

In 1987 the Cannabis Expiration Notice scheme decreased penalties for the personal use of cannabis in South Australia. Data from four National Campaign Against Drug Abuse (NCADA) household drug-use surveys covering the period 1985 to 1993 were analysed to measure the effect of the decriminalisation on cannabis use. The main outcomes used were the self-reported prevalence rates of having ever used cannabis and current weekly use. Logistic regression was used to control for the potentially confounding effects of age and sex. Other outcomes were rates of having ever been offered cannabis and willingness to use cannabis if offered it. Between 1985 and 1993 the adjusted prevalence rate of ever having used cannabis increased in South Australia from 26 per cent to 38 per cent. There were also significant increases in Victoria and Tasmania, and to a lesser extent in New South Wales. The increase in South Australia was not significantly greater than the average increase (P = 0.1). Adjusted rates of weekly use increased between 1988 and 1991 in South Australia, but did not change through 1993. Although the effect was in the direction of a greater increase in South Australia, this was not statistically significant when compared to increases in the rest of Australia (P = 0.07). The greatest increase in adjusted weekly use occurred in Tasmania between 1991 and 1993, from 2 per cent to 7 per cent. Although the NCADA survey data indicate that there were increases in cannabis use in South Australia in 1985-1993, they cannot be attributed to the effects of partial decriminalisation, because similar increases occurred in other states.

Down's syndrome in South Australia.

In a survey of Down's syndrome in South Australia, 921 persons, both living and deceased, were identified; 717 individuals with the disorder were living in South Australia. Cytogenetic confirmation of the diagnosis had been made in 774 cases. From 1955 to 1977, the over-all incidence of Down's syndrome at birth was found to be 1.175/1000 live births. The incidence of Down's syndrome was significantly lower over the last five years of this period than for the first 18 years; thus it appears that the incidence of Down's syndrome in South Australia is falling. Analysis of maternal age changes with time has not revealed any changes to the maternal age-specific rates for Down's syndrome, although the rate for mothers aged 25 years or younger appears to be falling. The proportion of Down's syndrome babies born to women aged 35 years or more has decreased from 65.7% for those born before 1950 to 30.4% for those born from 1975 to 1977; similarly, the median maternal age has fallen from 37.12 years to 28.25 years. Regression analyses of maternal age rates for Down's syndrome by single years have produced figures suitable for genetic counselling. A plea is made that Down's syndrome should become a notifiable condition.

The diabetes health care of Aboriginal people in South Australia (Part 1).

Although type 2 diabetes is a recognised health priority in South Australia, Aboriginal people with diabetes do not utilise the mainstream diabetes health services on a regular basis for health care. This means that Aboriginal clients have the potential to develop diabetes-related problems and, furthermore, are not in a position to make informed decisions about health care issues. This lack of client empowerment is contrary to the goals of contemporary diabetes health care and, as a result, Aboriginal clients suffer the consequences of ineffective management with a compromised lifestyle. To identify how this situation might be improved, a qualitative study funded by Diabetes Australia was undertaken in South Australia. The overall goal was, firstly, to identify the reasons why Aboriginal people with diabetes do not attend mainstream health agencies on a regular basis and secondly, if possible, to improve attendance. Thus, Aboriginal health professionals (n = 43) were recruited from the 8 statistical divisions of South Australia and interviewed about Aboriginal diabetes health care issues. In Part 1 of this series, the research findings indicated the beliefs and attitudes held by clients about diabetes, their lack of knowledge about management issues, their responses to diabetes, the effects of diabetes on their lifestyle and the strategies that diabetes health professionals used to help their clients deal with diabetes health issues. In Part 2 the research findings indicated the importance of the Aboriginal health worker to the successful diabetes management of Aboriginal clients, the constraints that affect the delivery of diabetes health care and the recommendations made by health professionals to improve the standard of diabetes health services.

A comparison between patients admitted to psychiatric hospitals in Botswana and South Australia.

Cohorts of patients admitted to psychiatric hospitals in Botswana and South Australia were compared. The psychiatric hospital in Botswana was used almost entirely for the care of patients with psychotic disorders, whilst one third of the patients in South Australia had either a neurotic or personality disorder diagnosis. A higher proportion of patients in Botswana than South Australia had had only a brief period of illness prior to admission. Violence was equally common amongst Tswana and Australian patients, but was directed outwards towards property and other people in Botswana and inwards towards the self in Australia. It was tentatively concluded that in both countries there was a group of severely ill patients who could not be handled without containment.

The sensitivity of ultrasound and serum alpha-fetoprotein in population-based antenatal screening for neural tube defects. South Australia 1986-1991.

OBJECTIVE: To determine the sensitivity of antenatal screening methods for neural tube defects in population-based screening in South Australia in 1986-1991, and whether ultrasound can replace serum alpha-fetoprotein screening in terms of achieving an equivalent level of sensitivity. DESIGN AND SETTING: Ascertainment of all births and terminations of pregnancy with neural tube defects from multiple sources for 1986-1991 in South Australia. Serum and amniotic fluid alpha-fetoprotein results were obtained from the only laboratory performing the tests as a Statewide antenatal screening programme, and information on ultrasound screening from case notifications, hospital case records and medical practitioners who cared for the women. SUBJECTS: All 243 births and terminations of pregnancy with neural tube defects in South Australia in 1986-1991. MAIN OUTCOME MEASURES: The sensitivity of individual screening methods and of all methods used, particularly for spina bifida. RESULTS: For pregnancies with neural tube defects screened by any method (serum alpha-fetoprotein, ultrasound or amniocentesis), 86% sensitivity was achieved. Ultrasound screening for anencephaly achieved 100% sensitivity even in low risk pregnancies, compared with 92% for serum alpha-fetoprotein. For spina bifida, the sensitivity of ultrasound screening increased with the level of risk in pregnancy: it was 60% in low risk pregnancies, which was equivalent to that of serum alpha-fetoprotein screening (64%); 89% in high risk pregnancies and 100% for women referred for confirmation of a suspected spina bifida by another ultrasonographer (chi 1(2) for trend = 23.49, P < 0.0001). Ultrasound screening in high risk pregnancies for spina bifida achieved higher sensitivity in teaching hospitals compared with other ultrasound services in the State (97% vs 65%), but sensitivity was equivalent for low risk pregnancies. It is estimated that, had the serum screening programme not been in place, the level of sensitivity achieved for spina bifida by ultrasound and amniocentesis would have been 62% compared with the actual situation of 76% with the programme in existence, a difference of nearly 15% (95% CI 2.5 to 26.7) (chi 1(2) = 5.45, P = 0.02). CONCLUSIONS: Antenatal screening for neural tube defects in South Australia achieved a higher level of sensitivity with the maternal serum alpha-fetoprotein programme in place. We conclude that the serum screening programme should continue in South Australia pending a significant improvement in the sensitivity of routine ultrasound screening for spina bifida.

Information management in primary medical care in South Australia.

The objectives of this study were to describe how GPs in South Australia manage and use office and clinical information, as well as their plans for the future. The study was set in a primary medical care centre in South Australia, and used a cross-sectional study with a mail questionnaire. Utilization of and satisfaction with office and clinical information management systems, with a focus on the use of patient summaries were outcome measures. A random sample was obtained from a register of GPs in South Australia that had been stratified into geographic regions based on socioeconomic indicators. Sixty-eight per cent of GPs approached responded (n = 315). There was no significant difference in response rate from each region. The use of computer applications was comparable to that in the general population. Half the GPs used index cards and 5% used computer-based records. Users of RACGP problem-oriented A4 folders were most (92%) and index card users least (65%) satisfied. The use of patient summaries could be improved. GPs planned to change to computer-based billing, more comprehensive paper-based records and computer-based patient records. Perceived reasons for and obstacles to change were documented. Factors that influenced the use of different forms of office and clinical information management were type and place of practice, staff employed, gender, a diploma in obstetrics, age, year of graduation, type of record used and satisfaction with it, vocational registration, FRACGP and FMP training. Given the pattern of utilization, generally low satisfaction and planned changes, there is an unmet need for useful office and clinical information management systems in general practice.(ABSTRACT TRUNCATED AT 250 WORDS)

Planning and implementing the first stage of an oral health program for the Pika Wiya Health Service Incorporated Aboriginal community in Port Augusta, South Australia.

The oral health of the Indigenous community in South Australia's mid-north has been a concern for some years. There has been a history of under-utilisation of available dental services by the local community. This is in part due to the services not meeting their cultural and holistic health care needs. The Indigenous community resolved to establish a culturally sensitive dental service within the Aboriginal Health Service already operating in Port Augusta in South Australia's mid-north. To achieve this, a partnership between Pika Wiya Health Service Incorporated, the South Australian Dental Service, the University of Adelaide Dental School and the South Australian Centre for Rural and Remote Health was formed. The aim of the project partners was to establish a culturally sensitive, quality dental service that caters to the needs of the Indigenous community serviced by Pika Wiya Health Service Inc. This article describes the process of planning and implementing the first stage of this project.
