The authors investigated the association between daily variations in ozone and cause-specific mortality. Fixed-site air pollution monitors in Montreal, Quebec, provided daily mean levels of ozone, particles, and other gaseous pollutants. Information on the date and underlying cause of death was obtained for residents of Montreal who died in the city between 1984 and 1993. The authors regressed the logarithm of daily counts of cause-specific mortality on mean levels of ozone, after accounting for seasonal and subseasonal fluctuations in the mortality time series, non-Poisson dispersion, and weather variables. The effect of ozone on mortality was generally higher in the warm season and among persons aged 65 years or over. For an increase in the 3-day running mean concentration of ozone of 21.3 microg/m(3), the percentage of increase in daily deaths in the warm season was the following: nonaccidental deaths, 3.3% (95% confidence interval (CI): 1.7, 5.0); cancer, 3.9% (95% CI: 1.0, 6.91); cardiovascular diseases, 2.5% (95% CI: 0.2, 5.0); and respiratory diseases, 6.6% (95% CI: 1.8, 11.8). These results were independent of the effects of other pollutants and were consistent with a log-linear response function.
BACKGROUND AND OBJECTIVE: Because of the paucity of information on the epidemiology of acute poisoning requiring intensive medical care, all such patients treated on the medical intensive care unit of the university hospital in Frankfurt am Main, Germany, between January 1993 and December 1999, were retrospectively evaluated. PATIENTS AND METHODS: Of the total of 6211 patients, 147 (80 women, 67 men, mean age 41 years, 2,3 %) were treated for acute intoxication in the intensive care unit. RESULTS: Reasons for admission to the intensive care unit were the need for ventilator treatment or intensive monitoring of vital functions. 52 % of the patients (n = 76) had attempted suicide, most of them using anti-depressive drugs (n = 19), paracetamol (n = 16), or benzodiazepines (n = 9). Two patients (2,6 %) died. 48 % of the patients (n = 71) were admitted because of accidental poisoning. Leading toxic agents in this group were heroin (n = 19), alcohol (n = 18) and digitalis (n = 12). 11 patients had taken herbicides, animal poisons or chemicals used at work or for house cleaning. In this cohort, three i. v. drug abusers (4,2 %) had died. Depending on the agents used, a variety of treatments (charcoal, antidots, extracorporal therapy) were undertaken. CONCLUSION: Due to excellent care in the prehospital phase and in the emergency room the number of patients requiring treatment on the intensive care unit was rather low. The mortality was in the range of other reports.
