Extensor carpi ulnaris (ECU) subsheath: Normal MRI appearance and findings in athletic injuries : 40

Purpose: First, to report ECU subsheath's normal MRI appearance and the findings in athletic injuries. Second, to determine the best MRI sequence for diagnosis. Methods and materials: Sixteen patients (13 males, 3 females, mean age 30.3 years) with ECU subsheath's athletic injuries sustained between January 2003 and June 2009 were retrospectively reviewed. Wrist MRI studies were performed on 1.5-T units and consisted of at least transverse T1 and STIR sequences in pronation, and FS Gd T1 in pronation and supination. Two radiologists assessed the following items, in consensus: injury type (A to C according to Inoue), ECU tendon stability, and associated lesions (ulnar head oedema, extensor retinaculum injury, ECU tendinosis and tenosynovitis). Then, each reader independently rated the sequences' diagnostic value: 0 = questionable, 1 = suggestive, 2 = certain. Follow-up studies were present in 8 patients. ECU subsheath's normal visibility (medial, central and lateral parts) was retrospectively evaluated in 30 consecutive control MRI studies. Results: FS Gd T1 sequences in supination (1.63) and pronation (1.59) were the most valuable for diagnosis, compared to STIR (1.22) and T1 (1). The study group included 9 type A, 1 type B and 6 type C injuries. There were trends towards diminution in pouches' size, signal intensity and enhancement in follow-up studies, along with tendon stabilization within the ulnar groove. In control studies, ECU subsheath's visibility in medial, central and lateral parts were noted in 66.7-80%, 63.3-80% and 30-50% respectively. Conclusion: ECU subsheath's athletic injuries are visible on 1.5-T MRI studies. FS Gd T1 sequences in supination and pronation are the most valuable.

Unplanned complex suicide by self-strangulation associated with multiple sharp force injuries: a case report.

In cases of ligature strangulation, the importance of distinguishing self-inflicted death from homicide is crucial. This entails objective scene investigation, autopsy and anamnesis in order to elucidate the manner of death correctly. The authors report a case of unplanned complex suicide by means of self-strangulation and multiple sharp force injury. The use of more than one suicide method, consecutively--termed unplanned complex suicide--gives this case particular significance. A brief discussion on this uncommon method of suicide is presented, particularly relevant to the attending forensic physician. In addition, a short overview of the entity of complex suicide is given.

A comparison of injuries among children and adult football (soccer) players

Football is a universal and an affordable game but we need to minimize the incidence of accidents among the increasing number of young football players. Our 11 year retrospective epidemiological study (1990-2000) of football injuries in children (N= 1000) was compared with those of adult players in the 2006 European Championship. This comparative study confirmed that the anatomical, biomechanical and biological conditions differ between adults and children and that they warrant particular attention to protect the latter vulnerable group against bone avulsions, overuse pathologies and fatigue-fractures. Injuries were shown to increase significantly with age up to 16 years (P=0.005). Children suffer mainly from contusions, fractures and sprain injuries. Head injuries were more common in boys (P=0.070), while girls were more prone to sprains. The types of injuries differ between adults and children (sprain versus fractures), the anatomical location of injuries is different (lower limbs in adults, lower and upper limbs in children), the circumstances of the injuries are different (contact in adults versus non-contact in children), and teenage girls have different types of injuries than teenage boys. An increased incidence of injuries is due to changes in the position of the center of gravity and in the morphotype during rapid growth. For these reasons it is mandatory to adapt the training to the age and sex of the players. It is unsafe to train children the same way as adults. The height, the weight and the speed of growth must be taken into account by the multidisciplinary team when organising the training programmes. -- Le football fait partie des sports les plus pratiqués au monde en raison de sa popularité et de son accessibilité économ ique. L'incidence des blessures liées à cette pratique doit être diminuée surtout chez les jeunes joueurs en raison de la croissance exponentielle du nombre de joueurs féminins et masculins. Une étude épidémiologique rétrospective sur 11 ans (1990-2000) a été réalisée chez les enfants victimes de blessures liées au football (N==1000), puis a été comparée aux données recueillies de l'UEFA lors d'un Championnat Européen en 2006 sur les lésions des joueurs adultes. Cette étude comparative confirme que les structures anatomiques, biologiques et les tensions biomécaniques chez l'enfant diffèrent de celles de l'adulte. Les enfants ont un risque plus élevé de souffrir d'avulsion osseuse et de fractures de fatigue que les adultes. Les blessures augmentent significativement avec l'âge jusqu'à 16 ans (P==0,005). Les traumatismes crâniens sont plus fréquents chez les garçons tandis que les entorses sont plus à risque chez les filles. Les adultes font plus souvent des entorses tandis que les enfants font plus de fractures. La localisation anatomique diffère également entre ces deux groupes (les membres inférieurs chez l'adulte et les membres inférieurs et supérieurs chez l'enfant). La circonstance des blessures diffère également (choc avec un autre joueur chez l'adulte et des blessures sans contact chez l'enfant). Chez les adolescents, les blessures des filles diffèrent de celles des garçons. L'augmentation chez les enfants de cette incidence est liée au déplacement lors de la croissance du centre de gravité, avec une maladresse accrue lors des phases de croissance. Pour toutes ces raisons, il est justifié d'adapter les entraînements de football en fonction de l'âge, du sexe et du morphotype. L'entrainement des enfants doit être différent de celui des adultes. Le poids, la taille et la vitesse de croissance doit être prise en compte dans des structures multidisciplinaires afin de permettre une meilleure longévité sportive des jeunes joueurs de football.

Resilience and Individualized Community Integration Interventions for Persons with Traumatic Brain Injuries

Investigators, caregivers, administrators and service users in the field of rehabilitation are increasingly interested in the concept of resilience, but the literature has very little to offer on interventions aimed at supporting the resilience of persons and their loved ones. This article describes the Personnalized Accompagnement Community Integration (ICII), which is intended to support the resilience of persons with moderate to severe traumatic brain injuries (TBIs). An ICII implementation is currently underway and is expected to support social participation and stimulate the resilience of persons with TBIs. It is based on four frames of reference: community integration founded on the person’s perception of their community integration, the ecosystemic model, the handicap production process (HPP) model, and the goal-setting process. ICII adopts an intervention perspective centered on the life plan of the person with a TBI.

Évaluation de la reconstruction des ligaments croisés post luxation aiguë du genou avec l’utilisation des ligaments synthétiques

La luxation du genou, bien que très rare, demeure une blessure dévastatrice car elle entraîne de multiples complications en raison de la nature complexe du traumatisme associé à cette lésion. La luxation peut résulter d'un traumatisme à haute ou basse énergie. Les blessures sévères aux ligaments et aux structures associées donnent à la luxation du genou un potentiel élevé d'atteinte fonctionnelle. Le traitement conservateur, qui était considéré comme acceptable auparavant, est maintenant réservé à un très faible pourcentage de patients. La reconstruction chirurgicale est maintenant préconisée dans la plupart des cas, mais de nombreuses options existent et le traitement chirurgical optimal à préconiser reste controversé. Certains chirurgiens recommandent la reconstruction complète de tous les ligaments endommagés le plus tôt possible, tandis que d'autres, craignant l’établissement d’arthrofibrose, limitent l'intervention chirurgicale immédiate à la reconstruction du ligament croisé postérieur et de l'angle postéro-externe. En raison des multiples structures endommagées lors d’une luxation du genou, les chirurgiens utilisent couramment la combinaison des autogreffes et des allogreffes pour compléter la reconstruction ligamentaire. Les complications associées au prélèvement de la greffe, l'allongement de la greffe, l’affaiblissement précoce du greffon ainsi que les risques de transmission de maladies ont poussé les chirurgiens à rechercher différentes options d’intervention. L'utilisation de matériaux synthétiques pour le remplacement du ligament lésé a été proposée dans les années ´80. Après une première vague d'enthousiasme, les résultats décevants à long terme et les taux élevés d'échec ont diminué sa popularité. Depuis lors, une nouvelle génération de ligaments artificiels a vu le jour et parmi eux, le Ligament Advanced Reinforced System (LARS) a montré des résultats prometteurs. Il a été utilisé récemment dans les reconstructions isolées du ligament croisé antérieur et du ligament croisé postérieur pour lesquelles il a montré de bons résultats à court et moyen termes. Le but de cette étude rétrospective était d'évaluer la fonction et la stabilité du genou après la luxation aiguë suivant la reconstruction des ligaments croisés avec le ligament artificiel de type LARS. Cette étude a évalué 71 patients présentant une luxation du genou et qui ont subi une chirurgie de reconstruction du ligament croisé antérieur et du ligament croisé postérieur à l'aide du ligament LARS. Suite à la chirurgie le même protocole intensif de réadaptation a été suivi pour tous les patients, où la mise en charge progressive était permise après une période d’environ 6 semaines pendant laquelle la force musculaire et la stabilité dynamique se rétablissaient. Les outils d’évaluation utilisés étaient le score Lysholm, le formulaire de «l’International Knee Documentation Committee», le «Short Form-36», les tests cliniques de stabilité du genou, l'amplitude de mouvement articulaire à l’aide d’un goniomètre et la radiographie en stress Telos à 30° et 90° de flexion du genou. Le même protocole d’évaluation a été appliqué au genou controlatéral pour des fins de comparaison. Les résultats subjectifs et objectifs de cette étude sont satisfaisants et suggèrent que la réparation et la reconstruction combinées avec ligaments LARS est une alternative valable pour le traitement des luxations aiguës du genou. Ces résultats démontrent que ces interventions produisent des effets durables en termes d’amélioration de la fonction et révèlent la durabilité à long terme des ligaments artificiels LARS. Les patients sont à la fois plus autonomes et plus satisfaits avec le temps, même si la luxation du genou est considérée comme une catastrophe au moment où elle se produit. Des études prospectives randomisées sont maintenant nécessaires afin de comparer la sélection de la greffe et le délai de reconstruction chirurgicale.

Compensation to Workmen for Industrial Injuries

This thesis Entitled compensation to workmen for industrial injuries.Evaluation of the different forms of liability for compensating industrial injuries makes it evident that the liability under the social insurance scheme is the most befitting one, as it eliminates the problem of evasion of liability by the employer by providing for sharing of liability. Liability for compensation under the workmen's Compensation Act, 1923 and the Employees' State Insurance Act, 1948 arises only in the case of accidents, arising in the course of and out of employment. Majority of the workers, covered by the workmen's Compensation Act, have supported lumpsum payment of compensation under the Act. It appears that workers are ignorant of the cemerits of lumpsum payment. So, the workers should be properly educated by the Inspectorate, proposed above, about the comparative advantages of periodical payments. It is suggested that the workmens Compensation Act, 1923 may be amended, imposing fee upon the parties for each adjournment. It is also suggested that provision may be made in the workmens Compensation Act, 1923 for the expeditious despatch of amendments of the Workmen's Compensation Act, 1923, the Workmens· Compensation Rules, 1924 and the Schedules, made from time to time, to the comrnissioners for workmens Compensation, This will help them mete out justice to an injured workman, as required by the changes in the law. The Employees' State Insurance Act, 1948 and the Rules may be amended, requiring the employers to provide the employees with necessary information, in the vernacular language, about the employment injury benefits available under the Employees' State Insurance Act, 1948 and the formalities for obtaining the same. This will help the illiterate employees, especially the casual ones, avail of employment injury benefits. Changes in the law, on the lines suggested above, are imperative to make the system of compensation for industrial injuries prove effective and beneficial to injured workmen.

What are the priorities for prevention and control of non-communicable diseases and injuries in sub-Saharan Africa and South East Asia?

Last year’s UN high level meeting sought to galvanise the international community into scaling up its response to the escalating global burden of non-communicable diseases. With resources tight, D Chisholm and colleagues examine which interventions should be given priority for action and investment

The Ergonomic Analysis and Back Injuries in Flexible Production System

Back injuries identification and diagnoses in the transition of the Taylor model to the flexiblemodel of production organization, demands a parallel intervention of prevention actors at work. This study uses simultaneously three intervention models (structured action analysis, muscle skeletal symptoms questionnaires and muscle skeletal assessment) for work activities in a packaging plant. In this study seventy and two (72) operative workers participated (28 workers with muscle skeletal evaluation). In an intervention period of 10 months, the physical, cognitive, organizational components and productive process dynamics were evaluated from the muscle skeletal demands issues. The differences established between objective exposure at risk, back injury risk perception, appreciation and a vertebral spine evaluation, in prior and post intervention, determines the structure for a muscle skeletal risk management system. This study explains that back injury symptoms can be more efficiently reduced among operative workers combining measures registered and the adjustment between dynamics, the changes at work and efficient gestures development. Relevance: the results of this study can be used to pre ent back injuries in workers of flexible production processes.

Incidência de lesões locomotoras no cavalo, diagnosticadas por raio-x

Na medicina equina, os problemas locomotores estão na origem da maioria das consultas veterinárias, provocando uma enorme preocupação para os proprietários e equitadores e exigindo um grande conhecimento por parte do veterinário. Assim, não são demais os estudos realizados nesta área, que permitem auxiliar os médicos veterinários sempre que se deparam com este tipo de problemas. Uma das ferramentas fundamentais para o diagnóstico das lesões ósseas e articulares nos membros é o raio-X. Desde que este foi tornado portátil, passou a ser um enorme aliado do veterinário, permitindo diagnósticos mais facilitados e imediatos no terreno. O objectivo da presente dissertação, para além de rever a bibliografia descrita acerca da incidência de lesões locomotoras, é também contribuir para a caracterização das lesões mais frequentes na medicina equina na população estudada que envolvam as estruturas óssea e articular dos membros do cavalo. As lesões locomotoras descritas no estudo, foram determinadas após uma observação rigorosa aos diferentes raios-X de 95 cavalos e os dados recolhidos foram tratados através de uma análise estatística utilizando o programa «SPSS®». Existe uma maior incidência de lesões nos membros anteriores quando comparado com os membros posteriores. Tanto o membro anterior direito, como o membro posterior direito são igualmente mais afectados do que os membros esquerdos, havendo também uma elevada distribuição das lesões em ambos os membros anteriores em simultâneo. No membro anterior, a lesão mais frequentemente diagnosticada é a osteoartrite, sendo a luxação uma das lesões menos encontradas. Para o membro posterior, é o esparvão que mais se diagnostica, contrastando com o síndrome podotroclear, que tem uma prevalência baixa. No membro anterior, a 3ª falange é uma das regiões mais afectadas, sendo a ulna uma das regiões menos afectadas. No membro posterior, é a região do curvilhão que representa um dos locais mais propícios a lesão, enquanto a 2ª falange é uma das regiões onde menos frequentemente se diagnosticam lesões no cavalo. Os resultados encontrados estão de acordo com a bibliografia descrita e sugerem a importância da continuidade deste tipo de estudos, nomeadamente abrangendo outras variáveis como a raça, a idade e o tipo de utilização do cavalo e, ainda, a utilização de outros métodos imagiológicos.
