The present study is part of a larger and ongoing research initiative investigating the cumulative cognitive effects of mild head injury in rugby union and focused specifically on high school rugby players. A comprehensive battery of neuropsychological tests was administered to top team high school rugby players (n = 47), and a non-contact sport control group of top team high school hockey players (n = 34). Direct comparisons of group mean scores and standard deviations across each neuropsychological test were carried out for the Total Rugby group versus the Total Hockey group as well as for the subgroups Rugby Forwards versus Rugby Backs. A correlational analysis was conducted to ascertain whether a relationship exists between the number of mild head injuries reported by the players and their cognitive test performance. Results of the group comparisons of means and variability on WMS Paired Associate Learning Hard Pairs - Delayed Recall provides tentative indications of the initial stages of diffuse damage associated with mild head injury in the rugby group and provides some evidence for impairment of verbal learning and memory in the Rugby Forwards group. The correlational analysis revealed no significant relationship between number of reported mild head injuries and cognitive performance. The findings and possible latent effects of the multiple mild head injuries reported by the rugby players are discussed in terms of brain reserve capacity theory and suggestions for future research are provided.

This thesis is the culmination of a program of research which initially began in 1995. It reflects a major professional interest in the imaging of sports injuries which developed gradually over the 10 year period between 1992 to 2001, based upon previous clinical experience and expertise in the management of musculoskeletal injuries and their anatomical and pathomechanical origins. The central theme of study relates to the use of cross-sectional imaging techniques to investigate the pathoanatomical basis for groin pain in althletes with particular reference to professional soccer players with chronic groin pain. The current thesis is based around two key postulates. Firstly, that most of the commonly diagnosed causes of groin pain in professional athletes are anatomically and functionally linked and, secondly, that modern cross-sectional imaging can demonstrate both the correct diagnosis and the underlying biomechanical causes. The program of study consists of three different but linked project themes. The first investigates the scope of the problem, i.e. the differential diagnosis and prevalence of groin pain in professional soccer players. The second investigates the precise "normal" anatomy, i.e. the gross topographical anatomy of the pubic symphysis and parasymphyseal regions as actually exists rather than the regional anatomy that appears in classical anatomical texts. The third builds upon the first two projects and, investigates the underlying pathomechanical processes using magnetic resonance imaging. The study results suggest that a unifying mechanism of injury exists which partly explains the diagnostic and therapeutic difficulties that occur in athletes with groin pain. It also demonstrates that better understanding of the true pubic symphyseal anatomy allows a more accurate diagnosis to be made and that magnetic resonance imaging can demonstrate the relevant underlying pathoanatomy. The thesis adds significantly to the body of scientific knowledge related to this important sports-related, clinical condition.

Closed head injuries are common occurrences in North America. Subsequent to a closed head injury (CHI), there are a number of symptoms which are commonly seen, one of which is fatigue. No studies were found which specifically address the issue of fatigue following CHI. Much remains unknown about this symptom, such as the percentage of individuals who experience fatigue as a problem after a CHI, the relationship between the degree of fatigue experienced and the severity of the injury, and the length of time that this problem persists following the injury. The present study explores and describes the problem of fatigue in a population of individuals following a CHI. In this study, 28 individuals who had experienced a CHI (14 with minor injuries and 14 with severe injuries) were each paired with a control subject who had not had a CHI and who was matched to the CHI subject in terms of age, sex, and personality characteristics. All subjects were asked to complete two brief questionnaires, two computerized tasks, and two self-report measures. All 28 subject pairs completed the first four measures and 22 of the pairs completed and returned the last two. The results showed a highly significant difference between the CHI and control groups on all measures. There were no differences between the CHI subgroups (minor end severe) on any of the measures, nor was there a relationship found between length of post traumatic amnesia or length of time post-injury and any of the measures, There was an interaction between the results on the measure of depression and four of the other five variables Further analysis demonstrated differences between the CHI and control groups on all measures after the depression scores were taken into account. These results indicate that fatigue is a serious, long lasting problem for this groups of individuals who have experienced a CHI. Suggestions for future research and for treatment are discussed. / Graduate

Os dados foram coletados dos prontuários do arquivo da Área de Cirurgia Buco-Maxilo-Facial da Faculdade de Odontologia de Piracicaba/Unicamp no período de 1999 a 2007. Foram encontrados 263 pacientes com 317 fraturas de côndilo mandibular. Houve 209 pacientes com fraturas unilaterais e 51 com fraturas bilaterais; com a proporção de 3,05:1 entre homens e mulheres respectivamente; média de idade de 28,4 anos; e predominância da raça branca. A causa mais comum de fratura condilar foram os acidentes de trânsito (57,8%). De forma geral, os dispositivos de proteção induziram uma redução nas fraturas condilares em acidentes de trânsito, contudo o capacete apresentou os piores índices de proteção que o cinto de segurança. As fraturas foram comumente associadas a outros tipos de trauma, sendo relação com a fratura de sínfise e a laceração em mento estatisticamente relevante. O tratamento conservador foi o mais aplicado com 78,55%, principalmente nas fraturas unilaterais, contra 21,45% dos tratamentos cirúrgicos, aplicados em maiores proporções nas fraturas bilaterais. A taxa de complicações foi menor no tratamento conservador com 7,9%, frente aos 33,33% no tratamento cirúrgico, o qual está exposto a mais variáveis como a acesso cirúrgico e a fixação interna rígida. A complicação mais comum foi a má-oclusão tanto no tratamento cirúrgico quanto no conservador. Houve uma relação significativa entre o consumo de substâncias nocivas a saúde (39,16% dos pacientes) e as complicações. Concluiu-s e q u e população afetada tem características urbanas, formada principalmente por adultos jovens do gênero masculino. O tratamento mais empregado é o conservador, o qual possui menores taxas de complicação, mas que não exclui o tratamento cirúrgico. / Abstract: The aim of this study was to evaluate the epidemiological characteristics of prevalence, treatment modalities and complication rates of the condylar fractures of the mandible. Data was collected from patients' records of Oral and Maxillofacial Surgery Area at Piracicaba Dental School - Unicamp from 1999 to 2007. The research results a sample of 263 patients with 317 condylar fractures. There were 209 unilateral fractures and 54 bilateral fractures, with a male:female ratio of 3.05:1,amean age of 28.4 years and white race predominance. Protective devices statistically decreased the prevalence of condylar fractures in car and bicycles accidents; however, seatbelts presents lesser protection in comparison with helmets. Fractures were usually associated with others traumas, with symphysis fracture and soft tissue injury to the chin region the most common ones. The conservative treatment was applied in 78.55%, mainly in unilateral fractures, against 21.45% of the surgical treatment, applied in the majority of the bilateral cases. The complication rate was lesser in the conservative treatment with 7.9%, in comparison with 33.33% of the surgical treatment cases that are more vulnerable to variables like surgical access and rigid internal fixation. The most common complication was malocclusion, both in surgical and non-surgical treatments. There were a significant relation between the use of harmful substances and complications (39.16% of the patients). In conclusion, the population affected had urban characteristics and is composed mainly by male young adults. The most adopted treatment was the conservative, that presented lesser complication rates, but it does not exclude the surgical treatment in some specific cases. / Doutorado / Cirurgia e Traumatologia Buco-Maxilo-Faciais / Doutor em Clínica Odontológica
