Cardiac hydatic cyst is a rare parasitic disease. We reported 45 patients with cardiac hydatid cysts; 33 of the 45 had a primitive, unique cardiac cyst. Altogether, 18 patients of our series were asymptomatic, and 27 patients complained of symptoms (dyspnea, chest pain, palpitations). In 11 cases the cyst was revealed by an acute complication; 3 of the 11 had pulmonary metastatic hydatidosis. The diagnosis was based on a series of test results in which hydatid serology and imaging (echocardiography, computed tomography, magnetic resonance imaging) played a predominant role. Cystopericystectomy is the gold standard procedure but is sometimes unsuitable for particular sites. In that case, a conservative approach (partial pericystectomy) is mandatory to preserve organ function. The operative mortality rate is 5.5%. Two pericardial recurrences were reported during follow-up.
IntroductionLes étudiants en début du cursus suivent la même formation hospitalo-universitaire, cependant, ils sont peu nombreux à choisir délibérément la médecine générale comme discipline d'exercice médical. Notre objectif est de préciser auprès des étudiants en médecine, les facteurs qui déterminent le choix de la médecine générale comme carrière et leur vision de cette discipline.MéthodesEtude descriptive transversale menée auprès d'un échantillon d’étudiants inscrits à la faculté de médecine de Sousse (Tunisie) pour l'année universitaire 2012-2013. Le recueil des données a été pratiqué par l'intermédiaire d'un questionnaire conçu pour les fins de ce travail. La saisie et l'analyse des données ont été effectuées par le logiciel SPSS 18.0.RésultatsNotre étude a porté sur 388 étudiants dont 69,5% étaient du genre féminin. L’âge moyen était de 22,1 ± 2,8 ans. Cent étudiants (25,8%) avaient un parent cadre de santé sans que cela n'ait une influence sur le choix de carrière. A l'entrée à la faculté, seulement 7,1% (n = 27) voulaient faire de la médecine générale leur carrière. Le changement de choix vers la médecine générale est statistiquement différent à l'entrée et à la sortie de la faculté chez les internes finissants.ConclusionAfin d'attirer davantage les étudiants vers la médecine générale, il serait judicieux d'adopter des changements majeurs touchant l'enseignement théorique et pratique et de modifier les conditions de travail en fonction des attentes des générations futures.
The energy sciences attempt to meet the increasing world-wide need for energy, as well as sustainability goals, by cleaner sources of energy, by new alternative sources of energy, and by more efficient uses of available energy. These goals are entirely consistent with the principles of green chemistry. This chapter concerns devices for creating electricity from light and for creating light from electricity. The major focus is on the photoproperties of ruthenium and iridium complexes, which have been proven to be a rich source of inspiration for conceiving photoactivated devices, including organic Figure 1: Relative abundance of different metals in the Earth's continental crust in units of atoms of the element per 10 6 atoms of silicon. Figure adapted from Ref. [1].photovoltaic (OPV) cells and organic light emitting diodes (OLEDs). The chapter reviews important already-in-use and potential applications of ruthenium and iridium complex-based photodevices, including the underlying mechanism behind their functioning and its investigation through computational chemistry approaches. It highlights the role of the information obtained from computational studies for the design of more efficient photodevices. The final part complements the discourse with a review of the progress on greener alternatives for OPVs and OLEDs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
