Carbon monoxide (CO) poisoning from coal and gas heaters is a public health concern in Turkey. This study estimated the prevalence, mortality rate and clinical predictors of severity of CO poisoning cases treated at the emergency unit of the Uludağ University Medical School, Bursa from 1996 to 2006. Of 305 patients treated over a 10-year period, only 1 case was recorded as suicide. The CO sourc...

The catalytic low-temperature oxidation of CO to CO2 with molecular oxygen is of particular industrial and ecological interest. Gas-phase reaction kinetics measurements in conjunction with first-principles calculations provide comprehensive insight into the mechanisms and energetics of the low-temperature CO combustion reaction catalyzed by small free palladium clusters Pdx + (x = 2−7). Similar...

Background: Dichloromethane (a chlorinated hydrocarbon) is normally used as a solvent. Dichloromethane poisoning has been reported from occupational exposure and the common routes of dichloromethane poisoning are ingestion and inhalation. Case presentation: We described a case of 51-year-old man who received subcutaneous injection of dichloromethane and presented with local wound necrosis at hi...

Butylphenyl-functionalized Pt nanoparticles (Pt-BP) with an average core diameter of 2.93 ± 0.49 nm were synthesized by the co-reduction of butylphenyl diazonium salt and H(2)PtCl(4). Cyclic voltammetric studies of the Pt-BP nanoparticles showed a much less pronounced hysteresis between the oxidation currents of formic acid in the forward and reverse scans, as compared to that on naked Pt surfa...

This clinical policy focuses on critical issues concerning the management of adult patients presenting to the emergency department (ED) with acute symptomatic carbon monoxide (CO) poisoning. The subcommittee reviewed the medical literature relevant to the questions posed. The critical questions are: Should hyperbaric oxygen (HBO2) therapy be used for the treatment of patients with acute CO pois...

background: in iran, methadone has been used for methadone maintenance treatment (mmt) as well as analgesic treatment in pain clinics. recently, there are some reports regarding accidental and intentional methadone poisonings and deaths. the aim of this study was to evaluate the trend of methadone poisonings and deaths during a 10-year period in tehran, iran. methods: this was a retrospective c...

Carbon monoxide (CO) poisoning is the most common type of accidental poisoning in the United States, contributing to an estimated 15,000 emergency department visits and 500 deaths in the United States each year [1]. The signs and symptoms of CO poisoning are diverse, ranging from headache, lethargy, dizziness, nausea and confusion to cardiac and neurological disturbances. Cardiovascular complic...

Diesel oxidation catalysts (DOC) were investigated for activity, NO conversion stability, and sulfur poisoning/regeneration on Pd/Al2O3, Pt/Al2O3, Pd-Pt/Al2O3 catalysts. The Pd/Al2O3 catalyst was more active CO hydrocarbon (C3H6 C3H8) oxidation, while the Pt/Al2O3 efficiently oxidized NO. formation of a Pd-Pt alloy in maintained Pd reduced phase, resulting superior activity this CO, C3H6, compa...

Carbon monoxide (CO) is an odorless, colorless, clear gas that attaches to the hemoglobin (Hb). Its affinity for Hb is approximately 200 times higher than that of oxygen, and CO blocks the capacity of Hb to carry oxygen (1). One of the most important effects of CO is tissue hypoxia, especially in the parts of tissues with the highest demand for oxygen and the lowest metabolic stores, such as th...
