    Literature Review of Benign Mullerian Papilloma Contrasted With Vaginal Rhabdomyosarcoma
    McQuillan, SK ; Grover, SR ; Pyman, J ; Jayasinghe, YL (ELSEVIER SCIENCE INC, 2016-08)
    STUDY OBJECTIVES: Benign müllerian papillomas of the genital tract are rare and, hence, can be mistaken for vaginal rhabdomyosarcoma on initial clinical review. This review of the literature will consolidate the previous cases of müllerian papilloma reported and looks for clues to differentiate the 2 entities. DESIGN AND SETTING: We provide a case report and literature review, with patients from a pediatric adolescent gynecology clinic in a tertiary center. METHODS: We conducted a search of English-language publications from 1951 (the first case report) until January 2014 by using the search words "Müllerian papilloma" and "prepubertal bleeding." References from previous published reports were also obtained for completeness. MAIN OUTCOME: Literature review of benign müllerian papilloma. RESULTS: Since 1951, 56 cases of müllerian papilloma were reported, including 4 cases at our institution. Comorbid conditions were found in 31.5% of cases (with 3 cases associated with mesenchymal tumors). The average length of time from onset of symptoms (primarily vaginal bleeding) to diagnosis was 6.7 months (range, 1 day to 3 years), with only 1 case diagnosed incidentally. Median age of presentation was 5 years (range, 1 day to 52 years). Most cases were localized and resected with ease. Histology reveals complex papillary lesions without cytologic atypia. CONCLUSION: Benign müllerian papilloma is distinguished from the more significant diagnosis of vaginal rhabdomyosarcoma by initial length of vaginal bleeding at presentation, lack of vaginal wall extension, ease of resection, and histopathology. This is compared with vaginal rhabdomyosarcoma which commonly exhibits both localized and distant spread.

    Anazodo, AC ; Gerstl, B ; Stern, CJ ; McLachlan, RI ; Agresta, F ; Jayasinghe, Y ; Cohn, RJ ; Wakefield, CE ; Chapman, M ; Ledger, W ; Sullivan, EA (MARY ANN LIEBERT, INC, 2016-09)
    PURPOSE: In Australia and New Zealand, there has not been a national systematic development of oncofertility services for cancer patients of reproductive age although many cancer and fertility centers have independently developed services. A number of barriers exist to the development of these services, including a lack of clear referral pathways, a lack of communication between clinicians and patients about fertility preservation, differences in the knowledge base of clinicians about the risk of cancer treatment causing infertility and fertility preservation options, a lack of national health insurance funding covering all aspects of fertility preservation, and storage costs and cultural, religious, and ethical barriers. The development of strategies to overcome these barriers is a high priority for oncofertility care to ensure that equitable access to the best standard of care is available for all patients. METHOD: The FUTuRE Fertility Research Group led a collaborative consultation process with the Australasian Oncofertility Consumer group and oncofertility specialists to explore consumers' experiences of oncofertility care. Consumers participated in qualitative focus group meetings to define and develop a model of consumer driven or informed "gold standard oncofertility care" with the aim of putting together a Charter that specifically described this. CONCLUSIONS: The finalized Australasian Oncofertility Consortium Charter documents eight key elements of gold standard oncofertility care that will be used to monitor the implementation of oncofertility services nationally, to ensure that these key elements are incorporated into standard practice over time.

    A Study Protocol for the Australasian Oncofertility Registry: Monitoring Referral Patterns and the Uptake, Quality, and Complications of Fertility Preservation Strategies in Australia and New Zealand
    Anazodo, AC ; Stern, CJ ; McLachlan, RI ; Gerstl, B ; Agresta, F ; Cohn, RJ ; Jayasinghe, Y ; Wakefield, CE ; Daly, G ; Chan, D ; Gilbert, L ; Kemertzis, M ; Orme, LM ; Wand, H ; Viney, R ; Gillam, L ; Deans, R ; Jetti, M ; Wu, J ; Chapman, M ; Ledger, W ; Sullivan, EA (MARY ANN LIEBERT, INC, 2016-09)
    Improvements in cancer diagnosis and treatment in patients of a reproductive age have led to significant improvements in survival rates; however, a patient's fertility can be affected by both cancer and its treatment. As survival rates improve, there is an expectation by clinicians and patients that patient's reproductive potential should be considered and protected as much as possible. However, there is a lack of data about current fertility preservation (FP) uptake as well as accurate data on the acute or permanent reproductive risks of cancer treatment, complications of FP in cancer patients, and the use and success of assisted reproductive technology by cancer survivors. FP remains a major gap in acute cancer management with lifelong implications for cancer survivors. The FUTuRE Fertility research team has established the first binational multisite Australasian Oncofertility Registry, which is collecting a complete oncofertility data set from cancer and fertility centers in Australia and New Zealand. Outcomes from the research study will monitor referral, uptake, and complications of FP, document patient's reproductive potential after treatment, and collect data on the use of assisted reproductive technology following cancer treatment. The data will be linked to other routine health and administrative data sets to allow for other research projects to be carried out. The changes in oncofertility care will be benchmarked against the Australasian Oncofertility Charter. The data will be used to develop evidence-based guidelines and resources, including development of accurate risk projections for patients' risk of infertility, allowing clinicians to make recommendations for FP or assisted reproductive technology.

    Genital warts in children: what do they mean?
    Jayasinghe, Y ; Garland, SM (BMJ PUBLISHING GROUP, 2006-08)
    Human papillomaviruses (HPVs) are a diverse family of viruses, of which 30-40 genotypes specifically infect the genital tract. Genital HPVs are largely transmitted sexually, with most infections being asymptomatic and transient. In contrast, persistent infection with oncogenic genotypes in a minority is a strong risk factor, for subsequent development of high grade dysplasia, the precursor lesion to cervical neoplasia, which generally occurs after a long latency period. It is unknown whether there is a disease correlate in children chronically infected with oncogenic HPVs. Low risk HPV genotypes 6 and 11 are the primary cause of condylomata acuminata, although in children non-genital genotypes are also found in a proportion, with the mode of transmission being either perinatal, horizontal, or sexual. The finding of asymptomatic HPV DNA in children, and correlation with live virus, infectivity, or disease is unclear. Long term follow up for children with anogenital warts is recommended, although there are no longitudinal studies available to clarify whether they are at risk of developing carcinoma in young adulthood.

    Current concepts in bone and reproductive health in adolescents with anorexia nervosa
    Jayasinghe, Y ; Grover, SR ; Zacharin, M (WILEY, 2008-02)
    Anorexia nervosa (AN) initiates an adaptive response at the level of the hypothalamus, which results in a complex interplay involving most elements of the neuroendocrine axis. Consequences of onset of disease in adolescence include amenorrhoea, pubertal arrest with potential loss of target height, and osteoporosis with reduced capacity for future attainment of peak bone mass. With recovery, delay in restoration of menses is common. Hormonal therapies for restoration of bone mineral density (BMD) in adolescents have shown limited efficacy. This review will discuss the reproductive endocrine effects of AN in adolescence, and discuss new investigative tools for monitoring restoration of reproductive function and BMD in this population.

    Web-Based Recruiting for Health Research Using a Social Networking Site: An Exploratory Study
    Fenner, Y ; Garland, SM ; Moore, EE ; Jayasinghe, Y ; Fletcher, A ; Tabrizi, SN ; Gunasekaran, B ; Wark, JD (JOURNAL MEDICAL INTERNET RESEARCH, 2012-02-01)
    BACKGROUND: Recruitment of young people for health research by traditional methods has become more expensive and challenging over recent decades. The Internet presents an opportunity for innovative recruitment modalities. OBJECTIVE: To assess the feasibility of recruiting young females using targeted advertising on the social networking site Facebook. METHODS: We placed an advertisement on Facebook from May to September 2010, inviting 16- to 25-year-old females from Victoria, Australia, to participate in a health study. Those who clicked on the advertisement were redirected to the study website and were able to express interest by submitting their contact details online. They were contacted by a researcher who assessed eligibility and invited them to complete a health-related survey, which they could do confidentially and securely either at the study site or remotely online. RESULTS: A total of 551 females responded to the advertisement, of whom 426 agreed to participate, with 278 completing the survey (139 at the study site and 139 remotely). Respondents' age distribution was representative of the target population, while 18- to 25-year-olds were more likely to be enrolled in the study and complete the survey than 16- to 17-year-olds (prevalence ratio=1.37, 95% confidence interval 1.05-1.78, P=.02). The broad geographic distribution (major city, inner regional, and outer regional/remote) and socioeconomic profile of participants matched the target population. Predictors of participation were older age, higher education level, and higher body mass index. Average cost in advertising fees per compliant participant was US $20, making this highly cost effective. CONCLUSIONS: Results demonstrate the potential of using modern information and communication technologies to engage young women in health research and penetrate into nonurban communities. The success of this method has implications for future medical and population research in this and other demographics.

    Breast Carcinoma in Young Women
    Simmons, PS ; Jayasinghe, YL ; Wold, LE ; Melton, LJ (LIPPINCOTT WILLIAMS & WILKINS, 2011-09)
    OBJECTIVE: To estimate the incidence of breast carcinoma and survival in patients younger than 25 years old, and to describe presenting clinical signs and symptoms of breast cancer in this age group. METHODS: A population-based descriptive study and case review in Olmsted County, Minnesota, was conducted using the resources of the Rochester Epidemiology Project. Participants were Olmsted County girls and women younger than 25 years old with histopathologically confirmed breast carcinoma diagnosed between 1935 and 2005. Nonresidents who presented to a medical facility within Olmsted County during this time period were included in some portions of the analysis. Main outcome measures were age-adjusted incidence, 5-year survival, and clinical presentation of breast carcinoma in girls and women younger than 25 years of age. RESULTS: With four breast carcinomas observed in Olmsted County residents over 1,201,539 person-years, the annual age-adjusted incidence of breast cancer in this population was 3.2 per million (95% confidence interval, 0.1-6.2). All four cancers occurred in the 20- to 24-year age group (age-specific incidence, 16.2 per million). Eight additional cases of breast carcinoma were identified in nonresidents. Delay in diagnosis was common. All had at least one feature worrisome for an aggressive neoplasm identified in their clinical history, on physical examination or by imaging. CONCLUSION: Breast carcinoma in young women is very rare, associated with delayed diagnosis, and usually associated with concerning features requiring biopsy. LEVEL OF EVIDENCE: III.

    Preventive Care and Evaluation of the Adolescent with a Breast Mass
    Jayasinghe, Y (THIEME MEDICAL PUBL INC, 2013-02)
    Adolescents have little knowledge of preventive breast care or breast screening, yet exposures in youth influence the risk of future breast disease.Nipple piercing increases the risk of trauma and breast infection. Alcohol consumption, smoking, nutrition, obesity, reproductive factors, previous cancer and chest radiotherapy, family history of breast cancer or genetic mutation increase the risk of breast cancer. Breast cancer is rare in adolescents and currently genetic testing is not recommended in those under 18 years, as medical surveillance is not usually recommended until around 25 years. Screening measures include clinical breast exam every 1 to 3 years, and breast self-awareness in healthy women from 20 years; and at least annual breast self examination, with annual clinical breast examination, mammography and magnetic resonance imaging in high-risk patients from 25 years. Breast ultrasound is used in diagnostic evaluation of breast masses in adolescents as mammography is less sensitive in young women.

    Measuring effectiveness of the cervical cancer vaccine in an Australian setting (the VACCINE study)
    Young, EJ ; Tabrizi, SN ; Brotherton, JML ; Wark, JD ; Pyman, J ; Saville, M ; Wrede, CD ; Jayasinghe, Y ; Tan, J ; Gertig, DM ; Pitts, M ; Garland, SM (BMC, 2013-06-19)
    BACKGROUND: The quadrivalent human papillomavirus vaccine has been provided in Australia through the National Human Papillomavirus Vaccination Program since April 2007. National registry data demonstrates good coverage of the vaccine, with 73% of school-aged girls having received all three doses. To evaluate the effectiveness of the program, we propose a two-pronged approach. In one (sub study A), the prevalence of the vaccine-targeted human papillomavirus genotypes in a population cohort is being estimated, and will be analysed in relation to vaccination status, cervical cytology screening status, demographic, social, behavioural, medical and clinical factors. In sub study B, the distribution of human papillomavirus genotypes detected in high grade cervical intraepithelial neoplastic lesions from vaccine eligible women is being assessed. METHODS/DESIGN: Sub Study A involves the recruitment of 1569 women aged 18-25, residing in Victoria, Australia, through Facebook advertising. Women who are sexually active are being asked to provide a self-collected vaginal swab, collected at home and posted into the study centre, where human papillomavirus DNA detection and genotyping is performed. Participants also complete an online questionnaire regarding sexual history, experience with, knowledge of, and attitudes towards human papillomavirus, the human papillomavirus vaccine, and cervical screening.Sub Study B will involve the collection of 500 cervical biopsies, positively identified as containing high grade cervical intraepithelial neoplastic lesions and/or adenocarcinoma in situ. Five serial sections are being taken from each case: sections 1 and 5 are being assessed to confirm the presence of the high grade cervical intraepithelial neoplastic lesions or adenocarcinoma in situ; human papillomavirus genotyping is performed on sections 2 and 3; single lesions are excised from section 4 using laser capture microdissection to specifically define causality of a human papillomavirus genotyping of each specific lesion. DISCUSSION: Australia is well placed to gain a clear and early insight into the effectiveness of the human papillomavirus vaccine in reducing the prevalence of human papillomavirus infection in young women, and any subsequent reduction in the prevalence of pre-cancerous cervical lesions, specifically high grade cervical intraepithelial neoplasia lesions, particularly of vaccine related types. The findings of a successful population based human papillomavirus program will have wide-reaching translational benefits across the globe.
