OBJECTIVES To investigate the acute cardiovascular effects of smoking shisha. DESIGN A cross-sectional study was carried out in six shisha cafes. Participants smoked shisha for a period between 45 min (minimum) and 90 min (maximum). The same brand of tobacco and coal was used. SETTING London, UK. PARTICIPANTS Participants were those who had ordered a shisha to smoke and consented to have ...

Background: The relationship between air pollution exposure and adverse birth outcomes such as low birth weight and IUGR was studied. However, very few studies evaluated the effect of air pollution emissions on spontaneous abortion. We examined association between spontaneous abortion of the first trimester of pregnancy and ambient concentrations of carbon monoxide in Tehran. Materials and Meth...

High inter- and intra-laboratory variability exists for the single-breath diffusing capacity of the lung for carbon monoxide (D(L,CO)) test. To detect small changes in diffusing capacity in multicentre clinical trials, accurate measurements are essential. The present study assessed whether regular D(L,CO) simulator testing maintained or improved instrument accuracy and reduced variability in mu...

Two parallel lines of investigation elucidating novel mechanisms by which iron (scanning electron microscopy-based) and carbon monoxide (viscoelastic-based) enhance coagulation and diminish fibrinolysis have emerged over the past few years. However, a multimodal approach to ascertain the effects of iron and carbon monoxide remained to be performed. Such investigation could be important, as iron...

The toxic effect of carbon monoxide on the animal organism has probably been known by man since the discovery of fire, and we know it was recognized as a dangerous poison in ancient times. It was Claude Bernard who first studied its mode of action, and he showed that blood treated with carbon monoxide was unable to bind oxygen. J. S. Haldane (1895) is considered as the pioneering investigator o...

Background: Carbon monoxide is an odorless, colorless and poisonous gas. Since there is currently no information on the prevalence of carbon monoxide poisoning in Mazandaran, this study aimed to investigate the prevalence of carbon monoxide poisoning and compare its prevalence with other poisonings recorded in Mazandaran Department of Forensic Medicine, from 2009 to 2011.Methods: This is a de...
