Scalpel slaves or cyborgs? : cosmetic surgery and embodied identity

This thesis explores individuals' experiences of cosmetic surgery in Melbourne. The research conducted with recipients of cosmetic surgery is a complex and ambiguous practice simultaneously encompassing pain and pleasure, agency and constraint, empowerment and conformity. By providing a more nuanced representation of people's experiences of such surgery, the thesis envisions a subjectivity that may better account for individuals' active and lived relationship to their bodies.

A comparison of the psychological outcomes of cosmetic surgical procedures

Studies of psychological outcomes of cosmetic surgery generally provide low standards of evidence due to significant methodological limitations and few studies have explored the outcomes of surgery types other than breast reduction or have compared post-operative outcomes for different surgery types. This study therefore aimed to explore the psychological outcomes and post-operative satisfaction of cosmetic surgery and compare the outcomes and satisfaction of participants undergoing different procedures.

Surveys were administered to a sample of 142 elective cosmetic surgery patients prior to surgery and six months after surgery. The surveys included standardised measures of body image (appearance evaluation, appearance orientation, body areas satisfaction), self-esteem, and mental health (psychiatric disturbance, anxiety, depression, dysmorphic concerns).

The findings revealed high rates of post-operative satisfaction and significant improvements in several dimensions of body image (appearance evaluation and body area satisfaction) and mental health (anxiety, depression, and dysmorphic concerns), but not self-esteem. Breast augmentation patients reported significantly higher improvement on appearance evaluation, significantly higher ratings of how likely they thought it was that they had achieved, or would achieve, what they were looking for in having the procedure, and a trend to report that the overall result of surgery was better than or as expected than rhinoplasty patients.

It is recommended that future research clarifies the degree to which self-esteem and indices of mental health improve after cosmetic surgery and fully establishes the impact of different procedures on psychological outcomes.

Why all directors should be shareholders in the company: the case against "independence"

It is argued that the shift towards more 'independent' directors, in the wake of corporate collapses, is a fundamentally bad move, undermining the rights and powers of minority shareholders - entrenches a second-rate corporate governance model, separation of ownership and control, in company law - rather than suggest cosmetic reform in an attempt to address the problem, it is proposed that all directors must have significant interest in the company they serve - directors' self-interests and the best interests of the company become intertwined - this is a more effective way of tackling the problem of separation of ownership and control

UV-shielding ceramic nanoparticles synthesised by mechanochemcial processing

ZnO, TiO₂ and CeO₂ are known as UV-shielding ceramic materials that have advantages over organic UV absorbers for their photo-stability and non-hazardous nature to human bodies. However, they normally cause low transparency in the visible-light range due to light scattering by large particles, which is undesirable for many transparent UV-blocking applications in cosmetic and plastic industries. Light-scattering efficiency of particles can be drastically reduced by decreasing the particle sizes down below 100 nm. This paper reviews recent investigation on the synthesis of ZnO and CeO₂ nanoparticles by mechanochemical processing. The resulting particles had a significantly low degree of agglomeration, having mean particle sizes of ~ 25 nm and ~ 10 nm, respectively. The aqueous suspensions of the nanoparticles showed strong absorption in the UV-light range and high transmittance in the visible-light range. Mechanochemical processing offers the possibility of industrial-scale production of transparent UV-shielding ceramic particles for many applications.

Skin pedagogies and abject bodies

How does the beauty industry ‘narrate the skin’? What does it teach women from different cultural groups about the female body? How does skin function as a site where female subjection and abjection are produced and reproduced? In this paper we examine the skin industry pointing to its extreme commodification of the female body and to the inexcusable pressure this places on females of most age and cultural groups.We focus on two examples. Firstly, we show what the skin industry teaches girls and women about both their skin colour ‘problems’ and desirable practices of whitening and, secondarily, tanning. Secondly, we consider what the cosmetic surgery industry teaches us about female bodily ‘imperfections’ linked to certain ethnic and racial groups and the necessary ‘remedies’. Overall we show how the socio-cultural normalization of perfect skin is a product of a range of contemporary and enduring social and cultural forces overlain by complex pedagogies of power, expertise and affect.

An international survey of contact lens prescribing for presbyopia

Purpose:  The aim was to determine world-wide patterns of fitting contact lenses for the correction of presbyopia.

Methods:  Up to 1,000 survey forms were sent to contact lens fitters in each of 38 countries between January and March every year over five consecutive years (2005 to 2009). Practitioners were asked to record data relating to the first 10 contact lens fittings or refittings performed after receiving the survey form.

Results:  Data were received relating to 16,680 presbyopic (age 45 years or older) and 84,202 pre-presbyopic (15 to 44 years) contact lens wearers. Females are over-represented in presbyopic versus pre-presbyopic groups, possibly reflecting a stronger desire for the cosmetic benefits of contact lenses among older women. The extent to which multifocal and monovision lenses are prescribed for presbyopes varies considerably among nations, ranging from 79 per cent of all soft lenses in Portugal to zero in Singapore. There appears to be significant under-prescribing of contact lenses for the correction of presbyopia, although for those who do receive such corrections, three times more multifocal lenses are fitted compared with monovision fittings. Presbyopic corrections are most frequently prescribed for full-time wear and monthly replacement.

Conclusions:  Despite apparent improvements in multifocal design and an increase in available multifocal options in recent years, practitioners are still under-prescribing with respect to the provision of appropriate contact lenses for the correction of presbyopia. Training of contact lens practitioners in presbyopic contact lens fitting should be accelerated and clinical and laboratory research in this field should be intensified to enhance the prospects of meeting the needs of presbyopic contact lens wearers more fully.

A seven year survey of the contact lens prescribing habits of Canadian optometrists

Purpose. Little is known about the contact lens prescribing habits of optometrists in North America. The purpose of this survey was to obtain data on the types of lenses and solutions prescribed by Canadian optometrists.

Methods. One thousand Canadian optometrists were surveyed annually over seven consecutive years (2000 to 2006; n = 7000) on their contact lens prescribing preferences. Each survey requested a range of information about the contact lenses prescribed to the first 10 patients after its receipt.

Results. Over this time period, 1008 (14.4%) of the surveys were returned, providing data on 9383 fits. During the seven-year period, the ratio of male:female fits was 1:2 (3123:6217, 43 not reported), with a mean age of 31.3 ± 13.6 years (range 2 to 82 years). The ratio of new fits to refits was 2:3 (3780:5518, 85 not reported), with 91.3% of all fits being soft contact lenses (SCL). Of the SCL fits, 59.5% were spherical, 28.5% toric, 9.7% multifocal, and 2.3% cosmetic tints. Gas permeable (GP) fits were 46.6% spherical, 18.6% toric, 19.5% multifocal, and 6.6% were for orthokeratology (OK). Over the seven-year period, SCL prescribed for continuous wear (CW) increased from 3.2% to 14.3% between 2000 and 2004 and reduced to 8.1% in 2006, for all fits. The use of mid-water content (MWC) materials decreased from 34.6% to 2.7% and the use of silicone hydrogel (SH) lenses increased from 61.4% to 96.2%, for all CW fits. GP lens continuous wear increased from 0.7% to 30.6% of all GP lens fits by 2006. Daily wear (DW) of SH lenses decreased from 49.6% (2000) to 33.7% (2004) and then increased to 86.1% in 2006, for SH fits. MWC SCL fit on a monthly planned replacement (PR) basis reduced in popularity over the seven-year period (75.0% to 39.9%) and in 2006 more patients were fit overall with SH lenses (42.9%). The use of non-PR SCL declined from 20.5% to 4.5% of all fits. Fitting of low-water content lenses also declined (15.1% to 7.0%). High-water content (5.4% to10.2%) and SH lenses (5.4% to 42.9%) both increased. By 2006, the majority of GP lenses fit were with high Dk (HDK) materials (50.3%).

Conclusions. The preferred contact lens modality for Canadian optometrists appears to be DW SCL, which are replaced monthly. The proportion of lenses used for CW peaked in 2004, with SH SCL being the preferred material. The market share for GP lenses remains relatively unchanged, with an increasing proportion used for OK and CW. The launch of DW SH lenses in 2004 resulted in a marked increase in their reported fits, with a similar effect following the launch of a HDK GP lens material for CW.

The frontotemporal-orbitozygomatic approach : reconstructive technique and outcome

Background The frontotemporal-orbitozygomatic (FTOZ) approach, also known as "the workhorse of skull base surgery," has captured the interest of many researchers throughout the years. Most of the studies published have focused on the surgical technique and the gained exposure. However, few studies have described reconstructive techniques or functional and cosmetic outcomes. The goal of this study was to describe the surgical reconstruction after the FTOZ approach and analyze the functional and cosmetic outcomes. Methods Seventy-five consecutive patients who had undergone FTOZ craniotomy for different reasons were selected. The same surgical (one-piece FTOZ) and reconstructive techniques were applied in all patients. The functional outcome was measured by complications related to the surgical approach: retro-orbital pain, exophthalmos, enophthalmos, ocular movement restriction, cranial nerve injuries, pseudomeningocele (PMC) and secondary surgeries required to attain a reconstructive closure. The cosmetic outcome was evaluated by analyzing the satisfaction of the patients and their families. Questionnaires were conducted later in the postoperative period. A statistical analysis of the data obtained from the charts and questions was performed. Results Of the 75 patients studied, 59 had no complications whatsoever. Ocular movement restriction was found in two patients (2.4 %). Cranial nerve injury was documented in seven patients (8.5 %). One patient (1.2 %) underwent surgical repair of a cerebrospinal fluid (CSF) leak from the initial surgery. Two patients (2.4 %) developed delayed postoperative pseudomenigocele. One patient (1.2 %) developed intraparenchymal hemorrhage (IPH). Full responses to the questionnaires were collected from 28 patients giving an overall response rate of 34 %. Overall, 22 patients (78.5 %) were satisfied with the cosmetic outcome of surgery. Conclusion The reconstruction after FTOZ approach is as important as the performance of the surgical technique. Attention to anatomical details and the stepwise reconstruction are a prerequisite to the successful preservation of function and cosmesis. In our series, the orbitozygomatic osteotomy did not increase surgical complications or alter cosmetic outcomes.
