Serotonin toxicity secondary to drug therapy, interaction or overdose is an increasing phenomenon worldwide. A proportion of patients require admission to an intensive care unit, but the treatment needed is usually supportive and of short duration. Prolonged ICU admission to control ongoing or long-lasting serotonin toxicity has not been reported previously. We describe three patients with prolonged serotonin toxicity, lasting 12-18 days. Symptoms of toxicity were easily demonstrable in each and were refractory to currently recommended therapies. We review the pharmacological mechanisms that led to prolonged serotonin toxicity in these patients. Predictors for prolonged serotonin toxicity include involvement of irreversible monoamine oxidase inhibitors (MAOIs) or slow-release preparations resistant to the effects of activated charcoal (eg, lithium). We also discuss the implications of prolonged toxicity for critical care management, to maintain optimal patient outcomes.

OBJECTIVE—To test the hypothesis that proposed amendments to the Occupational Safety and Health Act making all enclosed workplaces in Western Australia smoke free would result in a decrease in cigarette consumption by patrons at nightclubs, pubs, and restaurants without adversely affecting attendance. DESIGN—Cross sectional structured interview survey. PARTICIPANTS AND SETTING—Patrons of several inner city pubs and nightclubs in Perth were interviewed while queuing for admission to these venues. OUTCOME MEASURES—Current social habits, smoking habits, and how these might be affected by the proposed regulations. Persons who did not smoke daily were classified as "social smokers." RESULTS—Half (50%) of the 374 patrons interviewed were male, 51% currently did not smoke at all, 34.3% smoked every day, and the remaining 15.7% smoked, but not every day. A clear majority (62.5%) of all 374 respondents anticipated no change to the frequency of their patronage of hospitality venues if smoke-free policies became mandatory. One in five (19.3%) indicated that they would go out more often, and 18.2% said they would go out less often. Half (52%) of daily smokers anticipated no change to their cigarette consumption, while 44.5% of daily smokers anticipated a reduction in consumption. A majority of social smokers (54%) predicted a reduction in their cigarette consumption, with 42% of these anticipating quitting. CONCLUSIONS—One in nine (11.5%) of smokers say that adoption of smoke-free policies would prompt them to quit smoking entirely without a significant decrease in attendance at pubs and nightclubs. There can be few other initiatives as simple, cheap, and popular that would achieve so much for public health. Keywords: smoke-free policies; smoking behaviour
