Self-inflicted burns are rare in France, but they lead to major, often life-threatening complications. The authors reviewed medical data for patients hospitalized in a burn center from January 2004 to December 2008. Thirty-eight cases of self-inflicted burns were compared with 220 accidental burns. ⋯ Mean total burn surface area (41.5%) and mortality (36.9%) were higher in the self-inflicted burn population. By recognizing epidemiological characteristics and patients at risk, we can better classify lesions related to self-immolation. It is important for the forensic physician to consult survival details to correlate these data with the results of autopsy.

The aim of this retrospective study was to examine methyl alcohol intoxications in Trabzon (Turkey) and to determine any relations between the laboratory results and histopathologic changes. A total of 4492 forensic autopsies were performed from 1998 to 2008. Thirteen of the cases (0.3%) were because of methanol poisoning, and all were men. ⋯ In six cases, poisoning was because of consumption of the alcoholic beverage "Raki," while in five cases, poisoning was because of the ingestion of cologne. The products consumed were unknown in the other two cases because of insufficient history and data records. Mortality because of methanol poisoning may be prevented/decreased with the implementation of some precautions, such as public education regarding the harms of methyl alcohol, routine monitoring of the vendors that sell alcoholic beverages and cologne, and appropriate legal retribution for the illegal production of methanol.

Mitochondrial DNA (mtDNA) haplogroup discrimination is interesting not only for phylogenetic and clinical but also for forensic studies. We discriminated the mtDNA haplogroups of 570 healthy unrelated Han people from Zhejiang Province, Southeast China, by comprehensive analysis mutations of the hypervariable segments-I sequence and diagnostic polymorphisms in mtDNA coding region using real-time polymerase chain reaction (RT-PCR), which was compared with the widely used PCR and restriction fragment length polymorphism (PCR-RFLP) method. ⋯ Samples re-identified by PCR-RFLP showed the consistent results that were got with RT-PCR. In conclusion, the RT-PCR strategy appears to be an accurate, reproducible, and sensitive technique for the discrimination of mtDNA haplogroups, especially for mass screenings quickly and economically.

Carbon monoxide (CO) inhalation is one of the leading methods of suicide in the United States. A sharp increase in suicide by inhaling the CO produced from burning charcoal has been reported in parts of Asia; however, the incidence of this method has not been determined in a U. S. population. ⋯ During the period 1996-2009, we identified 158 cases of suicide by CO poisoning, with 125 because of automotive exhaust, 26 because of charcoal burning, and seven from other CO sources. While historical U. S. data indicate >99% of CO suicides in the United States occurring by automobile exhaust inhalation, in the most recent years analyzed, c. 40% of CO-related suicides in King County, Washington, were because of charcoal burning, indicating a possible shift in suicide trends that warrants further scrutiny in additional populations.
