Infection and sudden lethal upper airway occlusion - An overview.

A multitude of conditions may cause acute and unexpected upper airway compromise in both children and adults. These include mechanical blockage of the airways either from internal obstructions due to inhaled food or foreign objects, or from external compression. In addition, kinking of the airway in cases of positional asphyxia may compromise aeration.

Metal Railing Fences and Accidental Death.

Two cases of accidental deaths caused by the sharp ends of fence or gate posts are reported. Case 1: A 47-year-old man was found hanging by his ankle in an inverted position on fencing. He had attempted a shortcut to a railway platform by climbing over a metal rail fence.

Forensic features of pharmacobezoars.

Three cases of pharmacobezoars are reported to demonstrate typical autopsy findings and potential lethal mechanisms: (i) A 32-year-old woman died following an overdose of prescription medications. A gelatinous pharmacobezoar was found forming a cast of her bronchial tree. (ii) A 24-year-old woman also died following an overdose of prescription medications.

Patterned postmortem ant abrasions outlining clothing and body position after death.

Analysis of a series of cases where post mortem lesions had been caused by ant activity demonstrated two types of specific lesions, the first associated with clothing, and the second with the position of the body of the decedent. The first type of injury consisted of areas of abraded parchmented skin with well-defined straight edges that marked the perimeter of clothing. The second lesion consisted of circular abraded injuries that outlined the junction between the body and the surface that it was resting on, essentially tracing the outline of the point of contact.

Heat-related deaths in Adelaide, South Australia: review of the literature and case findings - an Australian perspective.

Heat waves are not uncommon in Australia, but the event of 2009 was particularly severe and ranks third of the 21 recorded heat wave events in south-eastern Australia in terms of the resulting mortality and morbidity. This is a review of Coronial autopsy findings in South Australia (which has an area of nearly 1 million square kilometres with a population of 1.6 million that predominantly resides within the region of the capital: Adelaide) during the period of the 2009 heat wave.

An audit of the toxicology findings in 555 medico-legal autopsies finds manner of death changed in 5 cases.

An audit of toxicological analysis in Coronial autopsies performed at Forensic Science South Australia was conducted on the cases of three pathologists. Toxicological analysis had been performed in 555 (68 %) from a total of 815 autopsies. It was found that the proffered manner of death was changed from the provisional report (provided immediately after the post-mortem examination) in five cases (just under 1 %) as a consequence of the toxicological findings.

Circumstances of death and diagnostic difficulties in brushfire fatalities.

The deaths of 10 bushfire (brushfire) victims (aged 2-59 years; M/F 1:1) from the files of Forensic Science SA in Adelaide, South Australia, over an 8-year period (January 2002 to December 2009) are reported. Nine of the victims were found in or near motor vehicles. Death was attributed to incineration (N = 5), trauma from bushfire-related vehicle crashes (N = 2), inhalation of products of combustion with hyperthermia (N = 1), inhalation of products of combustion (N = 1), and undetermined (N = 1).

Sudden death and the forensic evaluation of neurocutaneous syndromes.

On occasion the forensic evaluation of individuals who have died suddenly and unexpectedly may reveal intracranial vascular abnormalities such as capillary, venous- and arteriovenous malformations. Such vascular abnormalities may form part of a heterogeneous group of disorders called neurocutaneous syndromes and involve the skin, nervous system and other organ systems. These unusual conditions include Sturge-Weber, Osler-Weber-Rendu, Klippel-Trenaunay, Von Hippel-Lindau, Proteus and Wyburn-Mason syndromes in addition to ataxia telangiectasia.

Recovery of human remains after shark attack.

Two cases of fatal shark attack are reported where the only tissues recovered were fragments of lung. Case 1: An 18-year-old male who was in the sea behind a boat was observed by friends to be taken by a great white shark (Carcharodon carcharias). The shark dragged him under the water and then, with a second shark, dismembered the body.
