OBJECTIVE: To analyze the case characteristics of poisoning by exhaust gas of the imperfect combustion of natural gas and provide references for forensic identification and prevention of such accidents. METHODS: Twenty-two cases of poisoning by exhaust gas of the imperfect combustion of natural gas in Minhang District during 2004 to 2013 were collected. Some aspects such as general conditions of deaths, incidence time, weather, field investigation, and autopsy were retrospectively analyzed. RESULTS: In the 22 cases, there were 15 males and 16 females. The age range was between 2 and 82 years old. The major occurring time was in January or February (8 cases in each) and the cases almost occurred in small area room (21 cases). There was wide crack next to the exhaust port when the gas water heater was been used in all cases. CONCLUSION: There are more prone to occurrence of exhaust gas poisoning of imperfect combustion of natural gas in small area room with a ventilation window near the exhaust port of gas water heated. It shows that the scene of combustion exhaust gas poisoning should be more concerned in the cold season.

The methods of light microscopy, immunohistochemistry, and electron microscopy were employed to study the morphofunctional changes in epithelium of bronchial and respiratory segments of the rat lungs used as models of acute fatal poisoning with household gas. It was shown that this toxic effect induces the pathological process involving all the elements of the epithelial layer in the bronchial and respiratory segments of the lungs of experimental animals. At the ultrastructural level, mitochondria and endoplasmic reticulum structures are affected, with the death of epithelial cells leading to the damage of the aerohematic barrier. The toxic effect of the gaseous mixture on the membranes causes the destruction of various elements of the epithelial layer. The results of this study help to understand the mechanisms of death in the case of acute fatal poisoning with household gas.

In ambito penitenziario il suicidio e l'autolesionismo rappresentano quasi una caratteristica strutturale, rendendo la prevenzione un obiettivo primario. L'Amministrazione penitenziaria ha emanato in materia di prevenzione del suicidio un ampio spettro di provvedimenti. Il presente studio prende in esame la misura attualmente vigente in alcuni istituti di valutare i detenuti autorizzati all'utilizzo dello strumentario a gas, con monitoraggio delle condotte, da parte dello psichiatra.
