BACKGROUND There is a paucity of epidemiological data on neck injury in amateur rugby union populations. The objective of this study was to determine the incidence, severity, aetiology and type of neck injury in Australian men's amateur rugby union. METHODS Data was collected from a cohort of 262 participants from two Australian amateur men's rugby union(More)
The pathogenesis of brain edema in fulminant hepatic failure is incompletely understood. Our previous studies in models of this disease suggest the presence of a cytotoxic mechanism; as cortical astrocytes appeared predominantly swollen, we hypothesized that ammonia, metabolized to glutamine solely within this cell, could play a role in brain water(More)
BACKGROUND Numerous clinical tests are used in the diagnosis of anterior cruciate ligament (ACL) injury but their accuracy is unclear. The purpose of this study is to evaluate the diagnostic accuracy of clinical tests for the diagnosis of ACL injury. METHODS STUDY DESIGN Systematic review. The review protocol was registered through PROSPERO(More)
Sports chiropractic within Australia has a chequered historical background of unorthodox individualistic displays of egocentric treatment approaches that emphasise specific technique preference and individual prowess rather than standardised evidence based management. This situation has changed in recent years with the acceptance of many within sports(More)
BACKGROUND A common belief is that pain is uncommon and short lived in adolescents. However, the burden of pain in adolescents is unclear because of limitations in previous research. The aim of this study is to estimate the prevalence of headache, stomach-ache and backache in adolescents and to explore the extent to which these three forms of pain coexist(More)
BACKGROUND Chiropractors, physiotherapists, and osteopaths receive training in the diagnosis and management of musculoskeletal conditions. As a result there is considerable overlap in the types of conditions that are encountered clinically by these practitioners. In Australia, the majority of benefits paid for these services come from the private sector.(More)
Hyperammonemia and changes in brain monoamine metabolism have been proposed to contribute to the pathogenesis of the neuropsychiatric symptoms characteristic of human portal-systemic encephalopathy (PSE) resulting from chronic liver disease. Portacaval anastomosis (PCA) in the rat leads to sustained hyperammonemia and mild encephalopathy. In order to(More)
BACKGROUND The majority of Rugby Union (rugby) players participate at the amateur level. Knowledge of player characteristics and injury risks is predominantly ascertained from studies on professional or junior athletes in rugby. The objectives of the current study are to: (1) describe the health-related quality of life (HRQoL) and physical characteristics(More)
Portal-systemic encephalopathy (PSE) is characterized by a neuropsychiatric disorder progressing through personality changes, to stupor and coma. Previous studies have revealed alterations of serotonin and of its metabolite 5-hydroxyindoleacetic acid (5-HIAA) in brain tissue and CSF in experimental (rat) and human PSE. Increased brain 5-HIAA concentrations(More)
Quantitative receptor autoradiography was used to measure the densities of binding sites for the "peripheral-type" benzodiazepine receptor ligand 3H-PK11195 in regions of the rat brain 1, 3, 7 and 28 days following portacaval anastomosis (PCA) and in sham-operated control animals. The results demonstrate that densities of 3H-PK11195 binding sites were(More)
