Epidemiological and clinical aspects of 233 children below 14 years of age with acute carbon-monoxide poisoning are presented. Patients were recorded in the retrospective part of the M.S.P.C. (Multicentre Study of Poisoning in Children) at Genova, Torino and Trieste pediatric hospitals during 1975/90. Carbon-monoxide poisoning resulted to be a main toxic risk in children by considering its frequency and the severity of symptoms; three cases of death occurred. In particular, differences between symptoms in small children (under the age of 4 years) and adults are emphasised. This poisoning has to be suspected even in the presence of minor symptoms; the blood carboxyhemoglobin assay confirms the diagnosis and is useful to avoid further exposure.

Carbon monoxide (CO) is widely recognized as a significant environmental pollutant and is associated with numerous instances of accidental poisoning in humans. However, it also serves a pivotal role as a signaling molecule in plants, exhibiting functions analogous to those of other gaseous signaling molecules, including nitric oxide (NO) and hydrogen sulfide (HS). In plant physiology, CO is synthesized as an integral component of the defense mechanism against oxidative damage, particularly under abiotic stress conditions such as drought, salinity, and exposure to heavy metals.

Background: Acute carbon monoxide poisoning (COP) has been a common cause of emergency hospital visits over the past decade. Besides the immediate symptoms of poisoning, carbon monoxide exposure can cause various long-term complications, especially delayed neurological sequelae (DNS) and myocardial injury (MI).
Methods: This study retrospectively enrolled 502 patients with COP, including complete collection data, from the Taiwan National Poison Control Center between January 1, 2000, and December 31, 2015.

Introduction: Delayed neurological sequelae is a common complication following carbon monoxide poisoning, which significantly affects the quality of life of patients with the condition. We aimed to develop a machine learning-based prediction model to predict the frequency of delayed neurological sequelae in patients with carbon monoxide poisoning.
Methods: A single-center retrospective analysis was conducted in an emergency department from January 01, 2018, to December 31, 2023.
