Oral cancer in Australia: 1983-1996

Background: The aims of this study were to identify differences in oral cancer incidence and mortality between sexes, age groups, oral sites and Australian States and Territories and recent trends in oral cancer incidence, mortality and age-profile over time. Methods: Data were obtained from the Australian Institute for Health and Welfare and were age-standardized to the Australian 1991 Population Standard. Differences and trends were assessed with the Wilcoxon matched-pairs signed-ranks test and the Spearman correlation test, respectively. Results: In Australia in 1996, there were 2173 new oral cancers and 400 deaths due to oral cancer, the majority of oral cancers were in the 60+ age group, oral cancer affected men more than women (>2:1), lip cancer accounted for more than 50 per cent of oral cancers and the oral cancer mortality-to-incidence (M:I) ratio was greatest in ACT and NSW and least in QLD and SA. From 1983 to 1996, the annual incidence of lip cancer increased while the M:I ratio of lip cancer decreased. The annual incidence of cervical cancer decreased whereas the annual incidence of intra-oral cancer remained constant. The M:I ratio of cervical cancer was consistently lower than the MA ratio of intra-oral cancer. Conclusions; Reducing exposure to environmental carcinogens, increasing public awareness and population screening may reduce the incidence and mortality of oral cancer in Australia.

Conceptions of health and illness held by Australian Aboriginal, Torres Strait Islander and Papua New Guinea Health Science students

Health is considered to be a fundamental human right and developing a better understanding of health is assumed to be a global social goal (Bloom, 1987). Yet many third-world countries and some subpopulations within developed countries do not enjoy a healthy existence. The research reported in this paper examined the conceptions of health and conceptions of illness for a group of Aboriginal, Torres Strait Islander, and Papua New Guinea university students studying health science courses. Results found three conceptions of health and three conceptions of illness that indicated these students held a mix of traditional cultural and Western beliefs. These findings may contribute to overcoming the dissonance between traditional and Western beliefs about health and the development of health care courses that are more specific to how these students understand health. This may also serve to improve the educational status of Aboriginal and Torres Strait Islander people and potentially improve the health status within these communities.

Production of mosquitoes in rainwater tanks and wells on Yorke Island, Torres Strait: Preliminary study

The Torres Strait in northernmost Queensland, Australia, is subject to periodic outbreaks of dengue. A large outbreak of dengue 2 in 1996-97 affected five islands, resulting in 200 confirmed cases. On most of the affected islands, rainwater tanks were a common breeding site for vector mosquitoes. Rainwater tanks, wells and household containers filled with water are the most common breeding sites for dengue mosquitoes (Aedes aegypti), the primary vector of dengue in Queensland. We report on surveys conducted in February 2002 to measure the productivity of rainwater tanks and wells on Yorke Is. (Torres Strait), the first time the productivity of rainwater tanks has been measured in Australia. Of 60 rainwater tanks sampled, 10 had broken screens. Using a sticky emergence trap, 179 adult mosquitoes were collected, consisting of 63 Aedes scutellaris and 116 Culex quinquefasciatus. One unscreened tank produced 177 (99%) of the adults. A plankton net was used to sample 16 wells; 12 positive wells yielded 111 immature (larvae and pupae) mosquitoes, consisting of 57% and 43% Ae. scutellaris and Cx. quinquefasciatus, respectively. The apparent displacement of Ae. aegypti by Ae. scutellaris is discussed. Measures to reduce the likelihood of future dengue outbreaks are recommended.

Enhanced vector competence of Aedes aegypti (Diptera : Culicidae) from the torres strait compared with mainland Australia for dengue 2 and 4 viruses

Australian Aedes aegypti (L.) mosquitoes colonized from the Torres Strait and three mainland localities (Charters Towers, Townsville, and Cairns) were fed on blood suspensions containing dengue virus type 2 (DEN-2) or dengue virus type 4 (DEN-4). Variation was found in oral susceptibility to DEN-2 (59-99% infection) and DEN-4 (28-79% infection) among Ae. aegypti assayed for virus at 8, 12, 16, or 20 d after ingestion of infected blood. Torres Strait Ae. aegypti were the most susceptible to DEN-2 and were significantly more efficient in transmission to capillary tube at 16 d (76% transmission) than mainland Ae. aegypti populations (20-28% transmission). Torres Strait Ae. aegypti were also the most susceptible to DEN-4, although transmission did not vary significantly from mainland populations at 16 d (12% compared with 0-4%) or 20 d (16% compared with 4-16%). Disseminated infection (i.e., leg infection) with either DEN-2 or DEN-4 was not an accurate predictor of transmission potential. This study demonstrates differences among Australian Ae. aegypti populations in vector competence for DEN-2 and DEN-4. Torres Strait Ae. aegypti were more frequently infected and able to transmit DEN-2 at higher rates than mainland populations. These data indicate that the Torres Strait region is potentially more receptive to dengue transmission than mainland localities, a finding discussed with respect to past outbreaks.

Aboriginal and Torres Strait Islander health research and the conduct of longitudinal studies: issues for debate

The National Health and Medical Research Council, Research Agenda Working Group (RAWG), and the literature on Indigenous health have identified the need to fill gaps in descriptive data on Aboriginal and Torres Strait Islander health and noted both the lack of research with urban populations and the need for longitudinal studies. This paper presents some of the broad ethical and methodological challenges associated with longitudinal research in Indigenous health and focuses particularly on national studies and studies in urban areas. Our goal is to advance debate in the public health arena about the application of ethical guidelines and the conduct of longitudinal studies in Aboriginal and Torres Strait Islander communities. We encourage others to offer their experiences in this field.

Historical and dialectical perspectives on the teaching of Aboriginal and Torres Strait Islander musics in the Australian education system

Indigenous studies (also referred to as Aboriginal and Torres Strait Islander studies) has a double identity in the Australian education system, consisting of the education of Indigenous students and education of all students about Aboriginal and Torres Strait Islander cultures and histories. Through explanations of the history of the inclusion of Aboriginal and Torres Strait Islander musics in Australian music education, this article critiques ways in which these musics have been positioned in relation to a number of agendas. These include definitions of Aboriginal and Torres Strait Islander musics as types of Australian music, as ethnomusicological objects, as examples of postcolonial discourse, and as empowerment for Indigenous students. The site of discussion is the work of the Australian Society for Music Education, as representative of trends in Australian school-based music education, and the Centre for Aboriginal Studies in Music at the University of Adelaide, as an example of a tertiary music program for Indigenous students.

Guerra Fria na Região Amazônica: um estudo da Missão Venturini ao Suriname (1983)

O artigo aborda a evolução das relações bilaterais entre o Brasil e o Suriname durante a primeira metade da década de 1980, e especificamente o processo de tomada de decisão que culminou com o envio da assim chamada missão Venturini ao Suriname. O texto fundamentase em evidência documental primária resgatada em dois arquivos brasileiros. Conclui-se que os objetivos fundamentais propostos pelo governo brasileiro com relação ao Suriname - então controlado pelo comandante Desiré Delano Bouterse - foram alcançados, particularmente no que diz respeito a evitar a instalação do conflito Leste-Oeste na sensível fronteira norte do país e na região amazônica, em geral.
