Summary
The concept that immunomodulation using naturally-occurring bacterial agents can treat asthma has reached international prominence. This is backed by strong epidemiologic and clinical trial data. However, detailed knowledge of the immunological mechanisms involved is essential to allow more focused therapeutic agents to be developed. The proposed multi-disciplinary immunomodulation study in 200 children aims to provide this essential information using an advanced systems biology approach.

Summary
Benign epilepsy with centro-temporal spikes (BECTS, rolandic epilepsy) is a common cause of seizures in primary school children. Despite this it is poorly understood. Although seizures are infrequent, brainwave recordings (electroencephalography, EEG) reveal striking abnormalities present much of the time. Large, sharply contoured brain waves (spikes) are seen frequently, increasing during sleep.

Despite this it is poorly understood. Although seizures are infrequent, brainwave recordings (electroencephalography, EEG) reveal striking abnormalities present much of the time. Large, sharply contoured brain waves (spikes) are seen frequently, increasing during sleep. The pattern of the spikes, and the characteristic nature of seizures have suggested the epilepsy arises near the face area of the motor cortex, but this remains unproven. Functional magnetic resonance imaging (fMRI) is a safe and non-invasive way of imaging cerebral function, to reveal the brain at work . The technology is contributing to major advances in understanding of basic human functions such as language. Recent developments at the Brain Research Institute in Melbourne mean it is now possible to record EEG during fMRI. This has permitted visualisation of spike activity in the brain. The BRI is the only centre in Australia, and one of only a handful in the world that is able to perform such studies. One purpose of this study is reveal the location of spikes in BECTS. Recent studies have revealed subtle language and learning difficulties in BECTS children. Our preliminary EEG-fMRI studies have suggested spikes arise from brain regions adjacent to important language areas. It is possible that the frequent spikes of BECTS are interfering with adjacent cognitive processes. In addition to spike mapping, we will perform functional imaging of language to look for interactions between spike and language areas, and compare with patterns of language activation seen in normal children. The demonstration of spike related affects on cognition may lead to a reassessment of current epilepsy management strategies, which focus predominately on seizure control. This study, with researchers in Cairns and Melbourne, shares the benefits of world class research with regional Australia.Read moreRead less
Randomised Controlled Trial Of The Use Of Nitazoxanide Versus Placebo To Treat Gastroenteritis Among Aboriginal Children

Summary
Better treatment strategies are needed for Indigenous children with gastroenteritis. At present, most treatment is supportive only, with little effect on the duration of symptoms. Nitazoxanide appears to have effects on a broad range of pathogens which cause gastroenteritis, but it is not clear whether it will be of benefit in this population. We will compare the speed of symptom resolution in children who receive nitazoxanide with a group who receive a placebo instead.
A Randomised Controlled Trial Of Whole Body Cooling On The Outcome Of Term Infants With Hypoxic Ischaemic Encephalopathy

Summary
The aim of this project is to investigate whether the brain damage caused by a serious lack of oxygen around the time of birth can be prevented or reduced by cooling the baby's temperature to 34C for 72 hours. The consequences, of a lack of oxygen, to the brain, around the time of birth can be devastating. Over 30% of those babies with abnormal brain function soon after birth either die or survive with severe permanent brain damage. There is no specific treatment for these infants.

The consequences, of a lack of oxygen, to the brain, around the time of birth can be devastating. Over 30% of those babies with abnormal brain function soon after birth either die or survive with severe permanent brain damage. There is no specific treatment for these infants. Evidence from studies in animals, as well as human adults and a small number of newborn infants, suggests that moderate body cooling started soon after birth in babies with serious abnormal brain function might prevent or reduce brain damage. This project is a multicentre trial, where infants who have suffered from a severe lack of oxygen around birth, are randomised to body cooling to 34C for 72 hours. This will be started as soon as possible after birth at their hospital of birth. If the baby needs to be transported this will be started when the newborn transport team collects the baby for transfer to a newborn intensive care unit. This new treatment will be compared with maintaining the baby's temperature at 37C. This project will investigate a new, simple and pragmatic treatment that might reduce brain damage. If it finds that cooling infants who have been severely deprived of oxygen is an effective and safe treatment, the information will be applicable to any of the very large number of babies around the world who suffer from a serious lack of oxygen around the time of birth.Read moreRead less
The Distinctive Roles Of Tissue Transglutaminase Isoforms In Neuroblastoma

Summary
Neuroblastoma is the commonest solid tumour in early childhood. Neuroblastoma caused by N-Myc oncogene accounts for about one third of the disease and represents a more aggressive subtype with a worse clinical outcome. This project aims to identify factors responsible for N-Myc-induced neuroblastoma initiation and factors sensitizing neuroblastoma cells to anti-cancer drugs, and to provide the basis for clinical trials of a combination therapy in children with neuroblastoma.

Summary
Cerebral palsy is the most common physical disability in childhood. Our objective is to bring about a radical improvement in the treatment of individuals with cerebral palsy, both children and adults, and to determine better ways to assist their families. Emphasis will be placed on early detection of health issues and rigorous evaluation of management options. We will train more researchers and ensure that all the knowledge generated is made available to families and health care professionals.
Does Variable Ventilation Offer Physiological And Biological Benefits For The Preterm Lung?

Summary
Lung disease is a significant cause of illness at birth, subsequent breathing problems and death in very premature babies. We know that chronic preterm lung disease results in part from the immature state of the lung at birth, but it appears that inflammation of the lung also plays an important role. We, and others, have shown that this lung inflammation can be a response to injury from mechanical ventilation after birth.

We know that chronic preterm lung disease results in part from the immature state of the lung at birth, but it appears that inflammation of the lung also plays an important role. We, and others, have shown that this lung inflammation can be a response to injury from mechanical ventilation after birth. In the past, we have sought to strictly control the way that babies are ventilated. We have regulated the pressures used to inflate their lungs, the amount of volume delivered to the lung, the amount of time that the baby has to take a breath. This is a marked contrast to breathing patterns in healthy infants and adults, in which each of these things vary considerably from breath to breath. Recent studies have shown that the presence of variability in breathing patterns is actual essential to the process of staying healthy and maintaining resting lung volume above a critical lower limit. This study will provide unique insights into a new and potentially highly beneficial approaches to ventilation for preterm infants. We will determine if there is a significant clinical benefit of incorporating variability into the ventilatory waveform used to treat newborn babies with lung disease. has the potential to cause a paradigm shift in current concepts of preterm infant ventilatory strategies. Potential long term outcomes include significantly reducing illness and death associated with preterm birth, and promoting a healthier start to life for the over 6000 infants who require ventilatory assistance each year within the Australian and New Zealand neonatal network.Read moreRead less
