BACKGROUND: The parasite Toxoplasma gondii infects 30-60% of humans worldwide. Latent toxoplasmosis, i.e., the life-long presence of Toxoplasma cysts in neural and muscular tissues, leads to prolongation of reaction times in infected subjects. It is not know, however, whether the changes observed in laboratory influence the performance of subjects in real-life situations. METHODS: The seroprevalence of latent toxoplasmosis in subjects involved in traffic accidents (N=146) and in the general population living in the same area (N=446) was compared by a Mantel-Haenszel test for age-stratified data. Correlation between relative risk of traffic accident and a level of anti-Toxoplasma antibody titre was evaluated with the Cochran-Armitage test for trend. RESULTS: A higher seroprevalence was found in the traffic accident set than in the general population (Chi2MH=21.45, p<0.0001). The value of the odds ratio (OR) suggests that subjects with latent toxoplasmosis had a 2.65 (C.I.95= 1.764.01) times higher risk of an accident than the toxoplasmosis-negative subjects. The OR significantly increased with level of anti-Toxoplasma antibody titre (p<0.0001), being low (OR=1.86, C.I.95=1.14-3.03) for the 99 subjects with low antibody titres (8 and 16), higher (OR=4.78, C.I.95=2.39-9.59) for the 37 subjects with moderate titres (32 and 64), and very high (OR=16.03, C.I.95=1.89-135.66) for the 6 subjects with titres higher than 64. CONCLUSION: The subjects with latent toxoplasmosis have significantly increased risk of traffic accidents than the noninfected subjects. Relative risk of traffic accidents decreases with the duration of infection. These results suggest that 'asymptomatic' acquired toxoplasmosis might in fact represent a serious and highly underestimated public health as well as economic problem.
OBJECTIVE: To analyse the evolution of mortality attributable to alcohol (MAA) and the potential years of life lost (PYLL) due to alcohol consumption in Catalonia between 1988 and 1997. DESIGN: Retrospective, descriptive study of mortality. SETTING: Catalonia 1988-1997. PARTICIPANTS: Residents in Catalonia. Main measurements. Deaths occurring in Catalonia for the 36 causes of MAA between 1988 and 1997 were studied. The MAA, proportional mortality and the PYLL for each year were calculated on the basis of the population fractions attributable to alcohol (FPAA). Evolution of proportional mortality was studied with the chi2 test for linear trends. Evolution of the MAA and the PYLL were studied through regression straights and Pearson s correlation coefficient. RESULTS: 5.5% of deaths in Catalonia between 1988 and 1997 were attributable to alcohol. Men contributed most deaths (65.8%) and PYLL (80%). Traffic accidents were the most common form of death in men (15.3%), and cerebro-vascular diseases (25.9%) in women. Traffic accidents caused most PYLL (43.3%). Both a steady reduction in proportional mortality, dropping from 6.2% in 1988 to 4.8% in 1997 (chi2=213.4; P<.00001), and a fall in the total MAA (P<.05) and PYLL (P<.05) were found. CONCLUSIONS: There are gender differences in the numbers and most common causes of MAA. There was a steady drop in the number of MAA and PYLL during the period studied, basically due to the drop in deaths caused by traffic accidents. Similarly, proportional mortality dropped, drawing close to the 4% proposed in the Health Plan for Catalonia.
Inferior vena cava (IVC) aneurysms are extremely rare, with only 18 reported cases in the world literature. These aneurysms are categorized as acquired, congenital, or associated with arteriovenous fistulae. Thrombosis of an IVC aneurysm can lead to IVC syndrome characterized by massive lower extremity edema, pulmonary embolism, or even death. Therapeutic alternatives range from watchful waiting to operative resection. This report presents a case of an IVC aneurysm noted incidentally at the time of diagnostic computed tomography for the evaluation of blunt chest trauma following a motor vehicle collision. In addition, the classification, embryology, diagnosis, and management of this unusual clinical entity are reviewed.
