A visiting occupational therapy service to indigenous children in school: Results of a pilot project

The need for additional support for Indigenous children at school is well documented. Occupational therapists are well positioned to form part of this support. However, many occupational therapists report that Indigenous families do not access their services and when they do, the occupational therapist feels uncertain about how best to meet their needs. This article documents a pilot project which delivered occupational therapy services within several schools and preschools in Brisbane which had significant numbers of Indigenous students. The project was evaluated using a qualitative methodology and included focus groups and interviews with teachers and parents. The results indicated that in general the service provided valuable support to students, teachers and parents. In particular, providing the service within the school context was seen as critical to its success. Suggestions for improvements in future support services are also provided.

Moving and dancing towards decolonisation in education: An example from an Indigenous Australian performance classroom

This paper explores the special type of thinking, moving and dancing place which is opened up for decolonisaton when students engage in an embodied pedagogical practice in Indigenous education. The author examines what decolonisation means in this context by describing the ways in which the curriculum, the students and teacher, and more generally the discipline of ethnomusicology itself, undergo a process to question, critique, and move aside the pedagogical script of colonialism in order to allow Indigenous ways of understanding music and dance to be presented, privileged and empowered. Key questions are: What is the relationship between embodiment and disembodiment and decolonisation and colonisation? In what ways is embodiment more than, or other than, the presence of moving bodies? In what ways is performativity an aspect of power/knowledge/subject formations? How can it be theorised? What could the pedagogical scripts of decolonisation look like?

Seeing red: the use of Congo Red dye to identify cooked and damaged starch grains in archaeological residues

Starchy plant foods are significant in the diet of almost all peoples. Archaeologically, however, preservation of such plants is limited, and direct evidence of plant use by past people is also rare. Although starch grains can be preserved on artefacts used to process starchy plants, it is very difficult to identify grains damaged by processing methods such as milling or cooking. We present a method for identifying such damaged starch grains using Congo Red staining to identify cooking or milling activities in the past subsistence behaviour of Aboriginal people of southeast Queensland, Australia.

Nephron number, hypertension, renal disease, and renal failure

Essential hypertension is one of the most common diseases in the Western world, affecting about 26.4% of the adult population, and it is increasing (1). Its causes are heterogeneous and include genetic and environmental factors (2), but several observations point to an important role of the kidney in its genesis (3). In addition to variations in tubular transport mechanisms that could, for example, affect salt handling, structural characteristics of the kidney might also contribute to hypertension. The burden of chronic kidney disease is also increasing worldwide, due to population growth, increasing longevity, and changing risk factors. Although single-cause models of disease are still widely promoted, multideterminant or multihit models that can accommodate multiple risk factors in an individual or in a population are probably more applicable (4,5). In such a framework, nephron endowment is one potential determinant of disease susceptibility. Some time ago, Brenner and colleagues (6,7) proposed that lower nephron numbers predispose both to essential hypertension and to renal disease. They also proposed that hypertension and progressive renal insufficiency might be initiated and accelerated by glomerular hypertrophy and intraglomerular hypertension that develops as nephron number is reduced (8). In this review, we summarize data from recent studies that shed more light on these hypotheses. The data supply a new twist to possible mechanisms of the Barker hypothesis, which proposes that intrauterine growth retardation predisposes to chronic disease in later life (9). The review describes how nephron number is estimated and its range and some determinants and morphologic correlates. It then considers possible causes of low nephron numbers. Finally, associations of hypertension and renal disease with reduced nephron numbers are considered, and some potential clinical implications are discussed.

Guest Editorial: Some population perspectives on chronic kidney disease

In this issue of Advances in Chronic Kidney Disease, emphasis is placed on populationbased perspectives on kidney and related chronic diseases and their risk factors. The articles remind us that we must expand our views, break down specialty barriers, work on improved primary care models and prevention modalities, and think in terms of wholeof- person and whole-of-community, rather than in organ-specific approaches.

Epidemiology of open- and closed-globe trauma presenting to Cairns Base Hospital, Queensland

Purpose: To review the epidemiology of serious ocular trauma presenting to Cairns Base Hospital, from the far north Queensland health districts. Methods: A retrospective study of cases from January 1995 to November 2002 inclusive. Cases were analysed with respect to demographics, cause and nature of injury, method of transport and time to and type of ophthalmic treatment, and visual outcomes. Results: There were 226 cases identified, including 71 open-globe and 155 closed-globe injuries. The annual rate of injury was 3.7 per 100 000 for open-globe and 11.8 per 100 000 in total. The Aboriginal and Torres Strait Islander population from the far north Queensland districts showed a disproportionate incidence, with 38% of the total number of injuries, despite representing only 12.3% of the population. Assault in the Aboriginal and Torres Strait Islander population resulted in 69.6% of injuries in men and 75.8% of injuries in women. Of all assaults 76.2% were alcohol-related. The majority (71.5%) of injuries in the Caucasian population were due to accidental blunt and sharp trauma. In total, 77.4% of injuries occurred in men, with an average age of 31 years. Of all open and closed injuries in the study, a final visual acuity of 6/12 or better was achieved in 47.8% of eyes and a final visual acuity of 6/60 or less occurred in 17.7% of patients, 20.8% patients were lost to follow up. In total, 14.1% of open injuries required enucleation/evisceration. Conclusions: The incidence of ocular trauma in far north Queensland is equal to other Australian populations. However, there is a disproportionately high incidence in the Aboriginal and Torres Strait Islander population. Alcohol-related assault is a significant cause of visual loss in the Aboriginal and Torres Strait Islander population. Closed-globe injuries are more common than open globe; however, the latter have poorer visual prognosis. Initial visual acuity of all injuries correlated with final visual acuity.

Lessons in ethnonephrology

Only recently has the nephrology community moved beyond a fairly singular focus on terminal kidney failure to embrace population-based studies of earlier stages of disease, its markers and risk factors, and of interventions. Observations in developing countries, and in minority, migrant, and disadvantaged groups in westernized countries, have promoted these developments. We are only beginning to interpret renal disease in the context of public health history, social and health transitions, changing population demography, and competing mortality. Its intimate relationships to other health issues are being progressively exposed. Perspectives on the multideterminant etiology of most disease and the pedestrian nature of most risk factors are maturing. We are challenged to reconcile epidemiologic patterns with morphology in diseased renal tissue, and to consider structural markers, such as nephron number and glomerular size, as determinants of disease susceptibility. New work force models are mandated for population-based studies and intervention programs. Intervention programs need to be integrated with other chronic disease initiatives and nested in a matrix of systematic primary care, and although flexible to changing needs, must be sustained over the long term. Cross-disciplinary collaboration is essential in designing those programs, and in promoting them to health-care funders. Substantial expansion and restructuring of the discipline is needed for the nephrology community to participate effectively in those processes.
