少量矿物油燃烧所致烧伤特点

目的观察少量矿物油燃烧所致烧伤的特点,探讨其形成机制。方法介绍3例法医实际尸检案例所见烧伤,并将其特点与法医病理学文献所载烧伤特点比较。结果少量矿物油燃烧所致烧伤,一般仅限于皮肤的角质表皮层,或者真皮浅层;主要是Ⅰ度红斑烧伤;烟熏征象突出;毛发被烧程度不重,有的仅见一片发梢被烧卷的痕迹;局部烧伤与非烧伤部位之间界限分明;衣物上的烧痕,有时仅限于局部表层纤维。结论少量矿物油燃烧所致烧伤与通常所见到的有机物燃烧所形成的烧伤不同,其形成与少量矿物油燃烧时高温作用的持续时间短,产生较多烟雾有关。     

Forensic odontology lessons: multishooting incident at Port Arthur, Tasmania

On Sunday 28 April 1996 a lone gunman killed and injured many people at the historic penal settlement ruins at Port Arthur in South Eastern Tasmania, Australia. Thirty-two victims were shot dead and 19 were injured in a short time inside a cafe and along the roadway leading to the site entrance. The gunman then took one hostage to a nearby guest house which was occupied by a married couple. Police stood siege during the night. Early the next day the cottage began to burn and a man suspected to be the gunman eventually ran unarmed from the building with his clothes alight and was arrested. The house burned to the ground. Three bodies were later located in the burnt ruins.Forensic odontology played a role in the retrieval of evidence and identification of the incinerated victims. Lack of antemortem dental records for one victim necessitated the reliance on a single CT scan radiograph for matching with the remains. Fire scene procedures, evidence collection and other issues were reviewed.The overwhelming scale of this tragedy and its adverse effects on the Tasmanian community, especially the victims’ families and survivors, cannot be overestimated. While acknowledging this, it is important that lessons are learnt from tragedies such as these. This paper is presented with a view to assisting forensic odontologists in the investigation of complex incidents.
