Skin cancer clinics in Australia: workload profile and performance indicators from an analysis of billing data

Objective: To describe the workload profile in a network of Australian skin cancer clinics. Design and setting: Analysis of billing data for the first 6 months of 2005 in a primary-care skin cancer clinic network, consisting of seven clinics and staffed by 20 doctors, located in the Northern Territory, Queensland and New South Wales. Main outcome measures: Consultation to biopsy ratio (CBR); biopsy to treatment ratio (BTR); number of benign naevi excised per melanoma (number needed to treat [NNT]). Results: Of 69780 billed activities, 34 622 (49.6%) were consultations, 19 358 (27.7%) biopsies, 8055 (11.5%) surgical excisions, 2804 (4.0%) additional surgical repairs, 1613 (2.3%) non-surgical treatments of cancers and 3328 (4.8%) treatments of premalignant or non-malignant lesions. A total of 6438 cancers were treated (116 melanomas by excision, 4709 non-melanoma skin cancers [NMSCs] by excision, and 1613 NMSCs non-surgically); 5251 (65.2%) surgical wounds were repaired by direct suture, 2651 (32.9%) by a flap (of which 44.8% were simple flaps), 42 (0.5%) by wedge excision and 111 (1.4%) by grafts. The CBR was 1.79, the BTR was 3.1 and the NNT was 28.6. Conclusions: In this network of Australian skin cancer clinics, one in three biopsies identified a skin cancer (BTR, 3.1), and about 29 benign lesions were excised per melanoma (NNT, 28.6). The estimated NNT was similar to that reported previously in general practice. More data are needed on health outcomes, including effectiveness of treatment and surgical repair.

Taxonomy of Australian Funnel-web spiders using rp-HPLC/ESI-MS profiling techniques

The complex nature of venom from spider species offers a unique natural source of potential pharmacological tools and therapeutic leads. The increased interest in spider venom molecules requires reproducible and precise identification methods. The current taxonomy of the Australian Funnel-web spiders is incomplete, and therefore, accurate identification of these spiders is difficult. Here, we present a study of venom from numerous morphologically similar specimens of the Hadronyche infensa species group collected from a variety of geographic locations in southeast Queensland. Analysis of the crude venoms using online reversed-phase high performance liquid chromatography/electrospray ionisation mass spectrometry (rp-HPLC/ESI-MS) revealed that the venom profiles provide a useful means of specimen identification, from the species level to species variants. Tables defining the descriptor molecules for each group of specimens were constructed and provided a quick reference of the relationship between one specimen and another. The study revealed that the morphologically similar specimens from the southeast Queensland region are a number of different species/species variants. Furthermore, the study supports aspects of the current taxonomy with respect to the H. infensa species group. Analysis of Australian Funnel-web spider venom by rp-HPLC/ESI-MS provides a rapid and accurate method of species/species variant identification. (c) 2006 Elsevier Ltd. All rights reserved.

Asian Australian Citizenship as a Frame Enactment in the Parlimentary 'First Speech'

The parliamentary first speech is a site of discursive privilege that offers each parliamentarian an opportunity to articulate the principles and aspirations that underpin her or his entry into public life. When utilised by parliamentarians of Asian Australian backgrounds, these speeches embody a unique opportunity to comprehend how ethnic identity is performed amidst the numerous, competing interests by which legislators are bound and challenged. The construction and representation of Asian Australian identity in these contexts provide a fascinating opportunity to understand the junctures between ethnicity and Australian citizenship. This essay explores how Asian Australians may be subject to forms of 'coercive mimeticism' in certain social sites, and also how these hegemonic pressures may simultaneously present 'frames of enactment' through their performance.

From Zheng Qiang to Jiang Shuiying: The feminization of a revolutionary hero in Maoist theatre's 'Song of the Dragon River'

Since the 1980s, analysis of the representation of women in Maoist theatre has argued that the heroines of the Cultural Revolution model works (yangbanxi) were 'gender-less revolutionaries erased of anything feminine. This article challenges such a view through a case study of Song of the Dragon River in which the male hero of the 1964 spoken drama version was changed to a female in the 1972 yangbanxi adaptation. Evidence is presented that the characterization of the heroine in the latter work conforms closely not only with traditional beliefs in innate female characteristics but also with current Chinese beliefs in the characteristics of successful women in leadership. Rosemary Roberts is a lecturer in Chinese at the University of Queensland, Australia. She completed postgraduate studies at Beijing University in the early 1980s and has a PhD in Chinese literature from the Australian National University. She has published numerous articles and translations in the field of Chinese literature and culture and is currently writing a book on gender in Maoist theatre of the Cultural Revolution.

Oscar Asche's Modernisms: Flesh, Colour and Light

The article examines the early 20th century Australian actor, theater director, and writer Oscar Asche and how various aspects of his work are expressive of an aesthetic modernism. His theatrical productions with his wife Lily Brayton are discussed, as well as his solo projects like the highly acclaimed musical "Chu Chin Chow." Asche is described as a "vitalist."

Genetic parameters and predicted response to selection for lean growth in an Australian commercial nucleus pig herd

Genetic parameters for performance traits in a pig population were estimated using a multi-trait derivative-free REML algorithm. The 2590 total data included 922 restrictively fed male and 1668 ad libitum fed female records. Estimates of heritability (standard error in parentheses) were 0.25 (0.03), 0.15 (0.03), and 0.30 (0.05) for lifetime daily gain, test daily gain, and P2-fat depth in males, respectively; and 0.27 (0.04) and 0.38 (0.05) for average daily gain and P2-fat depth in females, respectively. The genetic correlation between P2-fat depth and test daily gain in males was -0.17 (0.06) and between P2-fat and lifetime average daily gain in females 0.44 (0.09). Genetic correlations between sexes were 0.71 (0.11) for average daily gain and -0.30 (0.10) for P2-fat depth. Genetic response per standard deviation of selection on an index combining all traits was predicted at $AU120 per sow per year. Responses in daily gain and backfat were expected to be higher when using only male selection than when using only female selection. Selection for growth rate in males will improve growth rate and carcass leanness simultaneously.
