A non-invasive method for postmortem temperature measurements using a microwave probe.

The use of the Microwave Thermography System in Forensic Medicine for the estimation of the post-mortem interval is explained. The Microwave Thermography System, a new device which is applied to this field for the first time, is described and its mode of operation is discussed. The main advantage of using this device for estimating the time after death is its ability to measure internal body temperatures by a non-invasive method. Using this device, it is possible now to measure temperatures of internal organs of the body by placing the sensory elements on the skin. Reliability of the system and factors affecting the accuracy of post-mortem temperature measurements have been assessed and discussed.

Internal carotid artery thrombosis following manual strangulation.

Thrombosis of the internal carotid artery is an unusual complication of neck compression, and even more infrequently observed in manual strangulation. It is important in such cases to exclude spontaneous thrombosis which may result from atherosclerotic narrowing of the vessel.

Medico-legal problems of ischaemic heart disease and myocardial infarction.

The medicolegal importance of ischaemic heart disease and myocardial infarction is summarized and discussed. Some theories of pathogenesis and aetiology of ischaemic heart disease, specially those which are more important and relevant to the medicolegal practice, are discussed. Results of the study of 33 cases of coronary artery atherosclerosis and myocardial infarction at different stages of development are presented. The condition of the coronary arteries and the myocardium is examined on gross and microscopical levels. Pathological findings are correlated with the clinical data obtained from the case histories and the summaries of the necropsy requests. No good correlation exists between the observed pathological changes and the clinical age of the infarction and, in most instances, the latter appears younger than the age estimated on the pathological ground alone. As far as the age of the infarction is concerned, most special histochemical staining methods are not preferable to the routine haematoxylin and eosin method. However, the former are efficient in demonstrating and confirming certain aspects of the infarction which cannot be ascertained by the latter method of staining. Pathological alterations associated with myocardial infarction at successive ages are explained and various methods of estimating the time of the infarction are discussed. Thus, gross and microscopical appearances of the acute, organizing and healed myocardial infarction are illustrated by photographs and the forensic applications of these morphological changes are discussed. Lastly, a rare case of an acute myocardial infarction associated with a heat stroke is presented and the medicolegal problems resulting from this case are discussed.

Homicide by electrocution.

Two cases of homicidal electrocutions are reported. A woman and her young son were killed in 1980 by her ex-husband. The criminal used electrical force as a method of killing. He wound flexible conducting wires around the limbs of the victims and switched on the current. He deliberately deceived his ex-wife by telling her that the circuits were incomplete and hence harmless. Thus, he persuaded her to be part of the circuits, so that a bulb could be lit when placed on her bare skin. The circumstances associated with these cases are given and the scene of the crime is described. Some important pathological aspects of electrical injuries are reviewed. The significance of pathological findings in the forensic investigations of electrocution is discussed.

Automatic rifle injuries: suicide by eight bullets. Report of an unusual case and a literature review.

A 25-year-old man committed suicide by shooting himself with eight bullets fired from a military rifle set on automatic. This rifle has two firing modes: an automatic mode and a self-loading, single-shot mode. Using this case as an example, some important aspects of firearm injuries are discussed with special emphasis on those points that are relevant to automatic military rifles and most applicable to forensic pathology practice. Some of the pathologic features of firearm wounds are reviewed and the role of the pathologist is discussed. Lastly, the most important points that help the pathologist to determine the type or nature of a firearm death--that is, whether it is an accident, homicide, or a suicide--are discussed. Classically, the number of the firearm wounds is used to differentiate suicide from homicide. As in the case reported here, however, when an automatic rifle or a military rifle set on automatic is used, the number of wounds is not a reliable indicator of the type of death.

Pathology of volatile substance abuse: a case report and a literature review.

The medicolegal importance of volatile substance abuse, as an example of toxicological deaths, is reviewed. A case of a 13-year-old boy who died after inhalation of volatile substances from a deodorant spray tin is presented. Another similar case has been summarized in the discussion. Different aspects of volatile substance abuse are considered with special emphasis on those facets which are relevant to forensic pathology practice. The most important pathological alterations associated with the acute and chronic abuse of volatile substances are discussed and some histological features of these conditions are illustrated with photographs. These include some microscopic changes of the central nervous system, respiratory system and the kidneys. The roles of the pathologist and the toxicologist in the investigations of the fatalities resulting from the volatile substance abuse are reviewed and practical points are explained. Lastly, some relevant legal points are discussed.
