How to join PubMed Commons JAMA. 1981 Oct 9;246(15):1698-700. Subacute carbon monoxide poisoning. Another great imitator. Grace TW, Platt FW. Abstract The illnesses of two patients with characteristic symptoms of subacute carbon monoxide poisoning were misdiagnosed initially. This resulted in the needless exposure of one patient and two relatives to a toxic environment. The cherry-red color of ...

Carbon monoxide clathrate hydrate is a potentially important constituent in the solar system. In contrast to the well-established relation between the size of gaseous molecule and hydrate structure, previous work showed that carbon monoxide molecules preferentially form structure-I rather than structure-II gas hydrate. Resolving this discrepancy is fundamentally important to understanding clath...

We present the case of a 70 year-old man with carbon monoxide poisoning following a house fire. A significant smoking history and likely underlying chronic lung pathology complicated treatment, as due to symptomatic retention of carbon dioxide we were unable to use high-flow oxygen to facilitate the elimination of carbon monoxide. We suggest that patients with risk factors for obstructive lung ...

Two cases are reported representing opposite ends of the spectrum of death as a result of carbon monoxide poisoning from car exhaust fumes. In one case, a women was reported to be found dead in bed early in the morning by her husband. The cause of her death, established by autopsy, was carbon monoxide poisoning. Toxicology examination indicated a car engine as the possible source of carbon mono...

Carbon monoxide is formed as a result of combustion of any carbon compound and can lead to hypoxia in many organs including the brain and the heart. Carbon monoxide poisoning in the United States is the leading cause of the fatal poisonings. In this study we present a case with no-known accompanying disease in the light of literature where myocardial infarction was developed as a result of carb...

Differential diagnosis of primary headache disorders can be challenging for physicians. Although the association of headache with acute carbon monoxide intoxication is very well-defined, in refractory nonspecific headaches associated with chronic low dose exposure to carbon monoxide, CO intoxication is usually overlooked, mostly due to vague symptoms. Herein we present a 15-year-old female pati...

The aim of this study is to investigate the problems caused by discharge of polluted air from tunnels into the environment with a specific focus on residential areas. In city tunnels, portal or stacks, pollutant management is a big challenge. Nowadays, air quality management, particularly in urban tunnels, is considered as a part of the ventilation system design. The goal is to see the environm...

A physiological role of carbon monoxide has been suggested for coronary myocytes; however, direct evidence is lacking. The objective of this study was to test the effect of chronic carbon monoxide exposure on the K(+) currents of the coronary myocytes. The effect of 3-wk chronic exposure to carbon monoxide was assessed on K(+) currents in isolated rat left coronary myocytes by the use of the pa...

Carbon monoxide, a gaseous activator of soluble guanylyl cyclase formed by a subtype of the enzyme heme oxygenase designated heme oxygenase-2 in vascular endothelium, has been found to dilate blood vessels independently from nitric oxide. Because of the parallels between nitric oxide and carbon monoxide, we speculated that estrogen might affect carbon monoxide production in vascular endothelium...

Carbon monoxide is a colorless, odorless, non-irritating, and tasteless gas that is ubiquitous in the atmosphere. It arises from both natural and anthropogenic sources. It is produced as a primary pollutant during the incomplete combustion of fossil fuels and biomass. Carbon monoxide is also produced indirectly from the photochemical oxidation of methane and other volatile organic compounds (VO...
