Variantes anatomiques de l’os temporal a preciser au chirurgien

L’os temporal présente plusieurs variantes dont certaines peuvent avoir un impact chirurgical. La chirurgie de l’oreille est non dénuée de risques. Les variantes anatomiques de l’os temporal sont importantes à connaitre et à préciser dans le compte rendu radiologique avant toute intervention sur l’oreille. La TDM est l’examen clé pour le bilan morphologique de toute oreille.Mots Clés : Variantes anatomiques, os temporal, TDM, risques.The temporal bone has several variants, some of which may impact surgical.

Forecasting Tunisian type 2 diabetes prevalence to 2027: validation of a simple model.

BACKGROUND: Most projections of type 2 diabetes (T2D) prevalence are simply based on demographic change (i.e. ageing). We developed a model to predict future trends in T2D prevalence in Tunisia, explicitly taking into account trends in major risk factors (obesity and smoking). This could improve assessment of policy options for prevention and health service planning. METHODS: The IMPACT T2D model uses a Markov approach to integrate population, obesity and smoking trends to estimate future T2D prevalence. We developed a model for the Tunisian population from 1997 to 2027, and validated the model outputs by comparing with a subsequent T2D prevalence survey conducted in 2005. RESULTS: The model estimated that the prevalence of T2D among Tunisians aged over 25 years was 12.0% in 1997 (95% confidence intervals 9.6%-14.4%), increasing to 15.1% (12.5%-17.4%) in 2005. Between 1997 and 2005, observed prevalence in men increased from 13.5% to 16.1% and in women from 12.9% to 14.1%. The model forecast for a dramatic rise in prevalence by 2027 (26.6% overall, 28.6% in men and 24.7% in women). However, if obesity prevalence declined by 20% in the 10 years from 2013, and if smoking decreased by 20% over 10 years from 2009, a 3.3% reduction in T2D prevalence could be achieved in 2027 (2.5% in men and 4.1% in women). CONCLUSIONS: This innovative model provides a reasonably close estimate of T2D prevalence for Tunisia over the 1997-2027 period. Diabetes burden is now a significant public health challenge. Our model predicts that this burden will increase significantly in the next two decades. Tackling obesity, smoking and other T2D risk factors thus needs urgent action. Tunisian decision makers have therefore defined two strategies: obesity reduction and tobacco control. Responses will be evaluated in future population surveys

Structure characterization, photoluminescence and dielectric properties of a new hybrid compound containing chlorate anions of zincate (II)

Este artigo propõe reflexões sobre Missa dos Quilombos, LP produzido e gravado ao vivo em 1982, com música e arranjos de Milton Nascimento para letras do sacerdote Pedro Casaldáliga e do poeta Pedro Tierra, reeditado em CD em 1995. Tomaremos os fonogramas como fonte maior de nossa análise, mas procurando articulá-los ao evento e à repercussão do rito religioso que gerou a gravação, na medida em que estes contribuem também para elucidar o projeto estético e político maior que engloba todos estes registros. Aliando a análise interdisciplinar dos estudos de canção e música popular à investigação historiográfica de fontes impressas, esperamos, finalmente, compreender a Missa e sua gravação como partícipes da história cultural brasileira, relevantes na retomada democrática justamente pela forma como nelas confluem linhas mestras da afirmação de matrizes culturais e religiosas afrodiaspóricas como elementos indispensáveis da história e da sociedade brasileira e latino-americana

The cactus effect An alternative to the lupin effect for increasing ovulation rate in sheep reared in semi-arid regions?

The present study evaluated the effects of supplementation with cactus cladodes on follicular dynamics and ovulatory response of sheep reared in semi-arid areas. A total of 76 ewes were distributed into two equal groups supplemented with either concentrated feed or cactus cladodes. After 30days of supplementation, no differences were found between feeding regimens on the final live weight (LW; 41.5±0.6 and 42.1±0.7kg in the Concentrate and Cactus groups respectively) and body condition score (BCS; 1.8±0.3 and 1.8±0.4 for Concentrate and Cactus group respectively). Moreover, no differences were found between the initial and the final values of both LW and BCS; thus, there were no effects of supplementation on any of both parameters. Analysis of follicular population showed that, during the follicular phase induced by ram effect, the number of follicles reaching ovulatory size increased in both groups. However, the number was always higher in Cactus ewes and, at oestrus, Cactus ewes had 1.6±0.2 and Concentrate sheep had 1.2±0.2 large follicles (p<0.05). Thereafter, ovulation rate was affected by duration of supplementation; being higher in sheep fed with cactus for 6-10days (1.7±0.1) than in ewes supplied with cactus for more than 11days (1.3±0.1; p<0.05), in sheep fed with concentrate for 6-10days (1.2±0.1; p<0.01) and even than in individuals subjected to classical flushing with concentrate (1.3±0.1; p<0.05). © 2011 Blackwell Verlag GmbH
