Sports-related chronic repetitive head trauma as a cause of pituitary dysfunction.

Traumatic brain injury (TBI) is recognized as a cause of hypopituitarism even after mild TBI. Although over the past decade, a growing body of research has detailed neuroendocrine changes induced by TBI, the mechanisms and risk factors responsible for this pituitary dysfunction are still unclear. Around the world, sports-especially combative sports-are very popular. However, sports are not generally considered as a cause of TBI in most epidemiological studies, and the link between sports-related head trauma and hypopituitarism has not been investigated until recently. Thus, there is a paucity of data regarding this important concern. Because of the large number of young sports participants with near-normal life expectancy, the implications of undiagnosed or untreated postconcussion pituitary dysfunction can be dramatic. Understanding the pathophysiological mechanisms and risk factors of hypopituitarism caused by sports injuries is thus an important issue that concerns both medical staff and sponsors of sports. The aim of this paper was to summarize the best evidence for understanding the pathophysiological mechanisms and to discuss the current data and recommendations on sports-related head trauma as a cause of hypopituitarism.

Addiction: l'égalité face aux substances [Addiction: are women and men equal?]

When illicit drugs are taken, men and women have a different biological response to drug used. Likewise, gender differences show more stigmas, more complex familial environment, and more history of sexual abuse for drug addicted women. The expression of psychiatric co-morbidities differs according to gender, with increased mood disorders, eating disorders, anxiety, and post traumatic disorders among drug addicted women.

Quelle attitude face à une masse médiastinale antérieure chez l'adulte [Management of anterior mediastinal masses in adults].

The discovery of an anterior mediastinal mass requires careful management with specific consideration of the pathology. More than 50% of all mediastinal masses seen in adults are in the anterior mediastinum. The most frequent diagnoses are thymoma, lymphoma, teratoma and benign thyroid tumours. 60% of cases are malignant. Often the clinical and radiological findings do not allow a definitive diagnosis and a histological diagnosis is often required to select the optimal treatment modality. The choice of biopsy technique depends on the localization of the lesion, clinical factors, and the availability of special techniques and equipment. Biopsy may be obtained by trans-thoracic puncture under computed tomography or ultrasound guidance, or by a surgical approach (mediastinotomy or thoracoscopy).

The significant behavioral aspects of adopted children within successful adoption in Romania

The human behavior is giving the entire picture of a person. The behavior is based on a complex combination of personal innate factors, experience and education and the social network within which the individual is integrated. Each moment the complex individual factors face external and internal environmental aspects which in turn, generate proactive and retroactive reactions. The adoption process is an important and challenging social experiment, bringing to the adopted child a new affiliation, social network, experiences and educational standards. This comes in his/her life after the trauma of losing his biological affiliation and social and emotional support. Which are the significant characteristics of the adopted child's behavior? Which are the behavioral characteristics of the adoptive child that guarantee the success of the domestic adoptions in Romania? These are the questions we are going to answer here based on the research done within FISAN(6) project. The 32 children, 11-16 years old, adopted by Romanian families, during the early ages (0-4 years), were evaluated with complex evaluation tools for children and parents. The adoptive families participating in the research live in the Western counties of Romania.Successful adoption is defined as secure attachment of the adopted child. The conclusions emphasize the importance of: the pro-social behavior, the loving behavior showed to the parents, the assertive behavior, the differentiations between parents and people outside the family, and between the two parents, and the humor. These behaviors displayed by the adopted children are the ingredients of a successful integration within the adoptive family.

INTERMED predicts non-return to work in an occupational rehabilitation setting for individuals with orthopaedic trauma-Part I

Introduction.- Knowledge of predictors of an unfavourable outcome, e.g. non-return to work after an injury enables to identify patients at risk and to target interventions for modifiable predictors. It has been recently shown that INTERMED; a tool to measure biopsychosocial complexity in four domains (biologic, psychologic, social and care, with a score between 0-60 points) can be useful in this context. The aim of this study was to set up a predictive model for non-return to work using INTERMED in patients in vocational rehabilitation after orthopaedic injury.Patients and methods.- In this longitudinal prospective study, the cohort consisted of 2156 consecutively included inpatients with orthopaedic trauma attending a rehabilitation hospital after a work, traffic or sport related injury. Two years after discharge, a questionnaire regarding return to work was sent (1502 returned their questionnaires). In addition to INTERMED, 18 predictors known at baseline of the rehabilitation were selected based on previous research. A multivariable logistic regression was performed.Results.- In the multivariate model, not-returning to work at 2 years was significantly predicted by the INTERMED: odds-ratio (OR) 1.08 (95% confidence interval, CI [1.06; 1.11]) for a one point increase in scale; by qualified work-status before the injury OR = 0.74, CI (0.54; 0.99), by using French as preferred language OR = 0.60, CI (0.45; 0.80), by upper-extremity injury OR = 1.37, CI (1.03; 1.81), by higher education (> 9 years) OR = 0.74, CI (0.55; 1.00), and by a 10 year increase in age OR = 1.15, CI (1.02; 1.29). The area under the receiver-operator-characteristics curve (ROC)-curve was 0.733 for the full model (INTERMED plus 18 variables).Discussion.- These results confirm that the total score of the INTERMED is a significant predictor for return to work. The full model with 18 predictors combined with the total score of INTERMED has good predictive value. However, the number of variables (19) to measure is high for the use as screening tool in a clinic.

Les sociétés d'état industrielles et commerciales togolaises face aux mutations socio-économiques contemporaines : le cas de Togo Télécom

Résumé L'étude de l'adaptation d'une entreprise aux mutations socio-économiques affectant son environnement sociétal donc de sa régulation, requiert de prime abord de comprendre et de caractériser ces mutations. I1 importe ensuite de déterminer les actions et stratégies déployées par cette entreprise en réponse aux pressions environnementales, ainsi que leurs éventuelles retombées sur les caractéristiques de l'environnement qui ont suscité ces réponses. Pour prendre part à cette réflexion, nous nous concentrons sur les conditions d'adaptation de la société d'État Togolaise :Togo Télécom, et nous tentons de confronter la réalité de cette évolution aux différents modèles de l'adaptation élaborés par la théorie des organisations. Une analyse concrète des enjeux soulevés par l'environnement de Togo Télécom et de leurs implications pour la société et pour la Nation a été réalisée au sein de l'organisation. Elle a pris appui sur les documents écrits pertinents à la recherche et sur le recueil des avis et perceptions des acteurs politiques, économiques, syndicaux et institutionnels concernés par l'avenir de l'entreprise. Les résultats indiquent que la société a su globalement entreprendre une réforme interne bénéfique qui lui a permis de faire face aux nouvelles réalités de son environnement malgré le boulet de la dette, tout en s'assurant l'attachement et le support de ses parties prenantes. Cette réforme a pu être mise en place notamment grâce à la remarquable capacité d'adaptation de ces parties prenantes et elle a également été à l'origine de la création d'un "réseau "redéfinissant l'organisation du travail sur le marché ainsi que les rôles, les problèmes et les caractéristiques de l'environnement sociétal. Afin de replacer cette relation particulière dans la théorie des organisations, la présente recherche s'applique à montrer comment le modèle de l'entreprise dominée par son environnement permet d'enrichir notre compréhension des solutions déployées par l'entreprise pour s'adapter; il est ici question d'analyser les comportements et réponses de la société à la lumière des principaux modèles théoriques, afin d'une part de déterminer comment chacun se prête à l'analyse d'un cas pratique et d'autre part de faire ressortir les forces et faiblesses de chaque modèle afin de tendre vers un modèle plus intégratif des réalités de notre cas. Dans cet ordre d'idée, notre recherche à l'instar de Morin (i98z) et de Giddens (1987), nous indique entre autres qu'il est primordial de ne pas isoler la théorie des organisations, dans des visions trop unilatérales, avec des points de vue partiels, mais d'adhérer à la réalité linéaire de la récursivité de l'adaptation des sociétés d'État industrielles et commerciales Africaines car ces organisations possèdent des propriétés spécifiques qui dépassent l'univers des ressources, des compétences ou des jeux d'acteurs qui les composent (Morin (198?)).

Le médecin face aux inégalités sociales de santé: quel pouvoir d'action [General practitioners facing social inequalities in health: which power to act?].

The link between social inequalities and health has been known for many years, as attested by Villermé's work on the "mental and physical status of the working class" (1840). We have more and more insight into the nature of this relationship, which embraces not only material deprivation, but also psychological mechanisms related to social and interpersonal problems. Defining our possible role as physicians to fight against these inequalities has become a public health priority. Instruments and leads, which are now available to help us in our daily practice, are presented here.
