Summary
The reproductive organs and genitalia in males and females experience a large increase in blood flow during sexual and reproductive activity. This increased blood flow (vasodilation) is a key component of penile and clitoral erection, and enhances secretion from the lining of the internal reproductive organs. Vasodilation during sexual activity is produced by a special sets of nerves receiving signals from the genitalia and the brain.

This increased blood flow (vasodilation) is a key component of penile and clitoral erection, and enhances secretion from the lining of the internal reproductive organs. Vasodilation during sexual activity is produced by a special sets of nerves receiving signals from the genitalia and the brain. In fact, Viagra works by enhancing and prolonging the actions of these nerves. An important part of this neural pathway is a group of nerve cells in the spinal cord that connects the central nervous system with peripheral nerves in the reproductive organs - these are called preganglionic neurons. Recently we discovered that a major pathway from the spinal cord to the pelvic blood vessels in females leaves the spinal cord at a different level (lumbar) from that thought previously (sacral level). Currently there is no information on how these lumbar preganglionic nerves in females are connected to other nerve pathways that are active during sexual activity, and how they integrate signals from both the internal organs and the brain. We will use an array of modern cellular techniques together with direct observation of dilation in isolated uterine arteries to discover how these nerve cells are wired up in circuits in the spinal cord. This information is vital for us to understand the factors producing increased blood flow in normal sexual activity, and how these might be altered in inflammation or in conditions where there could be selective damage to one nerve pathway and not the other, such as after pelvic surgery, spinal cord damage at different levels, or stimulation of the spinal cord for treatment of chronic pain. Our study also will help understand referred pain and sensations of discomfort in abdominal and pelvic organs.Read moreRead less
Pelvic organ prolapse in women is associated with poor quality of life. The standard treatment currently available for prolapse is surgery. The evidence for conservative management with physiotherapy is not clear. This randomised controlled trial will examine the effect of physiotherapy treatment, including pelvic floor muscle training, on prolapse symptoms and severity, compared with lifestyle advice only. Appropriate conservative management may reduce the need for surgery and associated costs.

Summary
Urinary incontinence is associated with significant personal shame and social stigma and affects around 10% of Australians. one-third of women over 60 years of age. Incontinence limits physical activity and this in turn can lead to loss of independence and poorer general health. Fewer than one-third of those with regular incontinence seek assistance. Pelvic floor muscle re-education by physiotherapists is the most commonly recommended method of conservative management for urinary incontinence.

Incontinence limits physical activity and this in turn can lead to loss of independence and poorer general health. Fewer than one-third of those with regular incontinence seek assistance. Pelvic floor muscle re-education by physiotherapists is the most commonly recommended method of conservative management for urinary incontinence. Pelvic floor muscle training is safe and effective and should thus be offered as the first choice of treatment for stress urinary incontinence. However there is still no strong evidence for the effectiveness of this intervention in the elderly and because of a perception by medical practitioners that pelvic floor muscle re-education is only effective in younger women, relatively few elderly women are referred to physiotherapy for management of incontinence. Although in clinical practice it is customary to complement pelvic floor muscle training with other forms of conservative management of incontinence such as bladder training, a recent influential study suggested that pelvic floor muscle training and bladder training were equally effective in patients with stress urinary incontinence. It is important to distinguish the relative effectiveness of these interventions used in isolation in order to ensure that urinary incontinence is managed in the most effective and efficient way. This project will therefore investigate the effectiveness of two conservative interventions, pelvic floor muscle training and bladder-behavioural training in women with stress urinary incontinence over 70 years of age. Moreover, strong evidence that conservative intervention is effective for urinary incontinence in the elderly will result in appropriate intervention being offered routinely as the first choice of treatment in older women.Read moreRead less

Summary
We recently identified two novel genomic regions with robust evidence for associaiton with endometriosis. The result does not give immediate insights into the genes or pathways contributing to disese because the genes in each region assocaited with increased risk need to be clearly identified. This project aims to find the gene or genes responsible in each region to help develop reliable disease biomarkers and effective preventative and therapeutic strategies for this important disease.

Summary
Chlamydia trachomatis infection is the most common notifiable sexually transmissible infection (STI) in Australia, with over 30,000 infections notified in 2003, rising by 20% each year. Infection with chlamydia can have considerable complications, particularly for women - it is a leading cause of pelvic inflammatory disease and tubal infertility. Unfortunately, as many as 85% of people with infection do not have any symptoms, so are unaware they have chlamydia; yet chlamydia is easy to diagnose ....Chlamydia trachomatis infection is the most common notifiable sexually transmissible infection (STI) in Australia, with over 30,000 infections notified in 2003, rising by 20% each year. Infection with chlamydia can have considerable complications, particularly for women - it is a leading cause of pelvic inflammatory disease and tubal infertility. Unfortunately, as many as 85% of people with infection do not have any symptoms, so are unaware they have chlamydia; yet chlamydia is easy to diagnose with urine tests and easy to treat with single dose antibiotics. Over 65% of infections diagnosed in women are among those aged 16 to 24 years. Internationally, screening programs for chlamydia have reduced the number of people with the infection and have also reduced the rate of complications arising from infection. However, Australia does not have a screening program and only tests about 4% of 16 to 24 year old women, the largest group at risk of infection, each year. We propose to conduct a study which tests the effect of using a computer based alert. This alert is designed to prompt doctors to discuss chlamydia testing with sexually active women aged 16 to 24 years. A group of general practices will be selected. We will randomly allocate some practices to have the alert installed on their computers and the remaining practices will receive no intervention. We will observe both groups of general practices over 12 months and compare their chlamydia testing rates among women aged 16 to 24 years. We estimate that the alert will increase testing rates from the 4% currently tested to 10%. By testing and treating more women with the infection, we can reduce the number of people in the community with the infection. We will also be collecting information about the dollar cost of chlamydia infection to the community. This study will produce valuable information which can be used by government to inform the design of future chlamydia screening and control programs.Read moreRead less
