Seasonal variation in carbon monoxide (CO) poisoning during 1969-78 was examined using the monthly hospital admissions and environmental weather data from Seoul, Korea. The results showed that there were nine times as many cases of CO poisoning in December as in August. CO poisoning cases were significantly correlated with temperature and domestic fires but not significantly with relative humid...

BACKGROUND Patients with acute carbon monoxide poisoning commonly have cognitive sequelae. We conducted a double-blind, randomized trial to evaluate the effect of hyperbaric-oxygen treatment on such cognitive sequelae. METHODS We randomly assigned patients with symptomatic acute carbon monoxide poisoning in equal proportions to three chamber sessions within a 24-hour period, consisting of eit...
