    Um estudo epidemiológico mediu a prevalência de pessoas que referiram acidentes por escorpião em uma amostra populacional do Areal, bairro Nordeste de Amaralina, Salvador, Bahia. Examinou-se uma amostra aleatória sistemática de 1367 indivíduos, correspondendo a 44,4% da população da área. Oitenta e dois indivíduos referiram haver sido picados por escorpião desde que residiam no Areal, resultando numa prevalência de 6% (IC 95% 4,7 - 7,3). A prevalência de pessoas picadas por escorpião aumentou nos grupos com maior tempo de residência no domicílio e com maior idade atual. Chamou atenção que 92,7% dos acidentes aconteceram dentro do domicílio. A incidência estimada para o período mais recente (janeiro a julho de 2000) foi de 1,15 casos/1.000 habitantes por mês. Este coeficiente compara-se ao mais elevado já referido na literatura especializada para uma área epidêmica para acidentes escorpiônicos.<br>An epidemiological study was undertaken to determine the prevalence of individuals who referred scorpion sting accidents in a population sample from Areal, a neighborhood northeast of Amaralina, Salvador City, State of Bahia, Brazil. A random, systematic sample of 1,367 individuals was taken, corresponding to 44.4% of the total population. Eighty-two residents referred scorpion sting since they were resident in Areal, giving a prevalence coefficient of 6% (95% CI 4.7 - 7.3). The prevalence of persons stung by scorpions increased according to greater time spent in the domicile and more advanced age. It was remarkable that 92.7% of the scorpions stings occurred within the home. The incidence coefficient estimated for the most recent period of time (January to July, 2000) was 1.15 cases/1,000 inhabitants per month, comparable to the highest ever reported for an epidemic area

    UMR AGAP - équipe AFEF - Architecture et fonctionnement des espèces fruitièresAs one of the most important and ancient fruit crops in the Mediterranean Basin, olive is characterized by a huge genetic patrimony, represented by cultivated and wild germplasm, ancient trees and related forms. The richness of this germplasm represents an unusual case among horticultural crops, due to species longevity, lack of new better performing genotypes, and the millennial tradition of cultivation. Focusing on a wide spectrum of genetic resources, their conservation, characterization, and management, this chapter tries to give an insight into the achievements and the necessities of this type of works in olive. Knowledge of existing diversity among the olive genetic resources is essential to maximize their conservation, safeguard, and exploitation

    BACKGROUND: Statin therapy reduces low-density lipoprotein (LDL) cholesterol levels and the risk of cardiovascular events, but whether the addition of ezetimibe, a nonstatin drug that reduces intestinal cholesterol absorption, can reduce the rate of cardiovascular events further is not known. METHODS: We conducted a double-blind, randomized trial involving 18,144 patients who had been hospitalized for an acute coronary syndrome within the preceding 10 days and had LDL cholesterol levels of 50 to 100 mg per deciliter (1.3 to 2.6 mmol per liter) if they were receiving lipid-lowering therapy or 50 to 125 mg per deciliter (1.3 to 3.2 mmol per liter) if they were not receiving lipid-lowering therapy. The combination of simvastatin (40 mg) and ezetimibe (10 mg) (simvastatin-ezetimibe) was compared with simvastatin (40 mg) and placebo (simvastatin monotherapy). The primary end point was a composite of cardiovascular death, nonfatal myocardial infarction, unstable angina requiring rehospitalization, coronary revascularization ( 6530 days after randomization), or nonfatal stroke. The median follow-up was 6 years. RESULTS: The median time-weighted average LDL cholesterol level during the study was 53.7 mg per deciliter (1.4 mmol per liter) in the simvastatin-ezetimibe group, as compared with 69.5 mg per deciliter (1.8 mmol per liter) in the simvastatin-monotherapy group (P<0.001). The Kaplan-Meier event rate for the primary end point at 7 years was 32.7% in the simvastatin-ezetimibe group, as compared with 34.7% in the simvastatin-monotherapy group (absolute risk difference, 2.0 percentage points; hazard ratio, 0.936; 95% confidence interval, 0.89 to 0.99; P = 0.016). Rates of pre-specified muscle, gallbladder, and hepatic adverse effects and cancer were similar in the two groups. CONCLUSIONS: When added to statin therapy, ezetimibe resulted in incremental lowering of LDL cholesterol levels and improved cardiovascular outcomes. Moreover, lowering LDL cholesterol to levels below previous targets provided additional benefit
