Summary
Atopic dermatitis, or eczema, is an increasingly common severe allergic condition affecting the skin that afflicts up to 30% of all Australian children. Eczema has significant financial impact on families as well on the health and well being of the affected child. The majority of asthmatics are also allergic, explaining why many children who suffer from eczema often go on to develop asthma as well.

Eczema has significant financial impact on families as well on the health and well being of the affected child. The majority of asthmatics are also allergic, explaining why many children who suffer from eczema often go on to develop asthma as well. A familial history of asthma or eczema is an important risk factors for a child developing the disorder, meaning that allergy is to a large extent determined by the genes we inherit from our parents. Our genes consist of four different building blocks, called nucleotides, which are identified by four letters: A, G, C and T. Each gene has a specific spelling of these four letters, although between any two people there will invariably be small single letter differences in the way a gene is spelt. Normally, these differences have no effect. In an allergic individual, however, these differences do have an effect. Identifying differences in the way a gene is spelt and why this should lead to eczema or asthma is a major research goal. In the past several years a number of genes have been identified that play an important role in allergy and we have recently identified a spelling difference in a new gene that we believe is important in the allergic response of eczema and asthma. At the moment, we can only guess how this gene might work. We know it is expressed in cells of our immune system that are important in allergy. We also suspect it might be an on or off switch for other genes important for allergy. This project will test these ideas and show how differences in the way this gene is spelt lead to differences in how this gene works. This will be important in adding another piece to the puzzle of how genes control allergy and could lead to better and earlier treatment of these disorders with improved health for affected children as well as adults.Read moreRead less

Summary
Rett syndrome (RTT) is the second most common cause of severe mental retardation in girls and women. Although two genes (MECP2 and CDKL5) responsible for RTT have been identified, we still do not understand how these genes affect brain function. The focus of this research project is to identify which proteins are controlled by CDKL5, with the express hope that a better understanding of these processes will allow us to design specfic therapies for this untreatable devasting disorder.

Summary
Diarrhoea is very common, especially in children but a cause is often not found. Believing there must be undiscovered viruses responsible, we developed a new method to look for them, and discovered one, which we have named adelavirus, in 17% of children with diarrhoea presenting to the WCH, Adelaide, over a 3 month period. 55% were hospitalised. This project proposes to investigate how widespread adelavirus infection is in the community and investigate how a vaccine might be developed.

Summary
Middle ear infection is a highly prevalent paediatric disease characterised by an inflammation of the middle ear and is the most prevalent illness of childhood. It is reported that greater than 80% of children have had at least one episode of acute otitis media by 3 years of age and almost 40% of children have more than 6 episodes by age 7 years.

It is reported that greater than 80% of children have had at least one episode of acute otitis media by 3 years of age and almost 40% of children have more than 6 episodes by age 7 years. The cause and pathogenesis of middle ear infection are multifactorial and influence of prevalence and chonicity of the infections. Prevention of bacterial middle ear infection caused by Streptococcus pneumoniae, nontypeable Haemophilus influenzae and Moraxella catarrhalis requires a much better knowledge of how these bacteria interact with each other and with the host. The poor efficacy of the current pneumococcal paediatric vaccine for preventing middle ear infections highlights this deficiency in our knowledge and will impede the development of a suitable multvalent vaccine to prevent infection by the 3 major bacterial pathogens. This study will investigate how the bacteria colonising the respiratory tract interact during infection and how they affect the host.Read moreRead less

Summary
The underlying genetic causes of idiopathic generalised epilepsies (IGE) are still largely unknown. In an animal model of IGE we have discovered novel genetic abnormalities an ion channel. This proposal will build upon these novel findings to examine the role these abnormalities have in determining the absence epilepsy phenotype and this work has the potential to provide vital information regarding the mechanisms by which this gene contributes to an IGE seizure phenotype.

This project will conduct the first prospective analysis of acute stress disorder and chronic traumatic stress symptoms in children, develop diagnostic guidelines to identify acutely traumatized children who are at risk of PTSD, and identify biological, cognitive, and familial factors that mediate PTSD development following trauma. Two hundred children (aged 7 - 12 years) who are admitted to hospital following a traumatic injury will be assessed for acute disorder within one month of the accident. They will be also be assessed for heart rate, blood pressure, memory patterns, and family responses during the initial assesment. Parents will also be assessed for their trauma reactions. All participants will be re-assessed at 6-months posttrauma, and again at 18-months posttrauma. These findings will establish the means to identify acutely traumatized children who are at risk of PTSD and open up opportunities for early intervention and prevention of PTSD.Read moreRead less

Summary
Motor vehicle accidents (MVAs) are relatively frequent major life trauma that represent significant life threatening experiences. Not surprisingly evidence suggests that MVAs represent a frequent trigger for the development of post traumatic stress disorder (PTSD), although studies have typically focussed upon adult survivors.

Not surprisingly evidence suggests that MVAs represent a frequent trigger for the development of post traumatic stress disorder (PTSD), although studies have typically focussed upon adult survivors. Local statistics indicate a significant proportion of children will experience a MVA of sufficient severity to warrant attendance at hospital. This project is of significance because it will provide badly needed information about the prevalence and course of emotional and behavioural problems in children following exposure to a serious MVA. More broadly the study should provide valuable information on post-traumatic stress responses in children. Furthermore, it will enable us to identify the factors that place children at particular risk of developing psychological problems following a MVA. This will provide information to help design of interventions to prevent the development of PTSD and other forms of psychopathology following MVAs. Such data will also permit identification of those children who are at particular risk of psychological morbidity after MVA trauma and for whom preventive interventions are most likely to be beneficial.Read moreRead less

We are exposed to a diverse and complex mix of indoor pollutants produced in many cases by everyday activities. Since we spend about 70-90% of our time indoors, the potential effect of these pollutants on our health is important and of concern. There is a growing number of scientific studies that confirm the importance of indoor air pollution to our health. Two indoor pollutants commonly found in the home are nitrogen dioxide (NO2) emitted from gas appliances and environmental tobacco smoke (ETS). ETS, or passive smoking, is known to increase lower respiratory tract illness in children, asthma, lung cancer and cardiovascular disease. Studies have shown that NO2 may increase respiratory symptoms and exacerbate the response of asthmatics to allergens such as house dust mites. In this project we extend our earlier work on indoor air pollution, with the aim of evaluating simple and effective ways to improve air quality in the home. Parents of school children from the Newcastle area will be invited to participate in the study. Parents will receive information about the health risks of indoor air pollution and advice on how to decrease the levels in their home. We will monitor the air quality in each participant's home to see whether the education program has helped parents to decrease the levels of NO2 and ETS in their home. We will also examine whether a reduction in these pollutants has improved the lung health of the children in the study.Read moreRead less

How do psychiatrists read the potential for such change in the discourse of their patients? This collaborative project, between psychiatry and linguistics, investigates the role of language in providing both strategies for change and evidence of change in the Conversational Model of psychotherapy. The project will examine the linguistic patterns that occur in the forms of talk used by therapists employing the Conversational Model of Psychotherapy, in order to produce a better understanding of certain mental illnesses, and how they can be treated. Specifically, it will: 1. describe, linguistically, four key discourse categories of the Conversational Model that are taken as indicators of progress in patients with Borderline Personality Disorder 2. explain the therapeutic work of such discourse - what is it about these particular language resources that facilitates the observed changes in patients' discourse and mind? 3. assess the stability of key discourse categories of the Conversational Model, and test the ability of a linguistic profile to reliably distinguish between key therapeutic categories as used by different clinicians. The positive effects of Conversational Therapy on incidence of self harm, violence, hospital stays, drug use and self-reported symptoms in this group have been well documented and are especially impressive given that many of the patients in these studies had been turned away from other forms of treatment as unresponsive. By understanding better how this therapy works in a patient group that is typically resistant to treatment but responsive to this particular treatment, we hope to improve health outcomes for people diagnosed with Borderline Personality Disorder. In the longer term we expect this research to help improve techniques for enhancing the mental health of Australians more generally.Read moreRead less

Traumatic brain injury in children is common with more than 2000 new cases a year in Queensland and Victoria alone. Many children who experience a brain injury go on to have long-term difficulties such as significant educational and social problems.

Many children who experience a brain injury go on to have long-term difficulties such as significant educational and social problems. Post-traumatic stress occurs in children following traumatic physical injury. However it is not clear to what extent this is so for children who have received a traumatic brain injury. Furthermore, when there is a traumatic brain injury and traumatic stress, it is not clear how these interact, how they influence long-term outcomes, and what factors such as pre-injury functioning and family support and distress mediate outcomes. These issues are very important since effective rehabilitation of children following traumatic brain injury is essential to maximise long-term functioning and minimise disability. To be effective, rehabilitation must be guided by the knowledge about key factors that determine the recovery process. This study aims to provide answers to these questions by following two cohorts of children (aged 6-14) over 18 months after receiving a traumatic brain injury. In total 240 children will be recruited from Brisbane and Melbourne hospitals. They will be assessed at three, six, twelve and eighteen months post-injury using measures of cognitive, psychological and social functioning. Information on parent distress and behaviours will also be obtained. The information obtained will provide the basis for the development of a specific rehabilitation strategy for children with traumatic brain injury, including information on strategies to help prevent any confounding impact of post-traumatic stress on recovery.Read moreRead less
