[Gunshot wounds of the head in soldiers wearing military helmets-- general aspects and experiments and observations on the biomechanics and wound morphology].

With respect to wound ballistics, the situation is different if the person wearing a military helmet suffers head injuries from a bullet. The mechanisms of injury were investigated in four experimental series and supplemented by a case history. The study showed surprising results: in the majority of cases, the helmet does not protect the wearer, but instead intensifies the damage caused by the bullet. The reasons for this phenomena are changes in the stability of the projectile and deformation of or damage to the bullet. All of these mechanisms result in the bullet striking the tissue with higher energy. In this investigation, Kevlar helmets were also tested, which are not penetrated by 9 X 19 mm parabellum bullets. Even so, however, severe injuries of the skull and brain can occur because the projectile causes intensified impressions on the skull under the helmet and, in addition, an acceleration of the head.

[A fatality caused by heparin overdose].

Because of suspected pulmonary embolism 550.000 I.U. of heparin were administered instead of 55.000 I.U. of heparin within 24 h to a 62 year old patient. The man died because of cerebral hemorrhage the following day. Autopsy findings are reported and difficulties in medical expertise are discussed.

[Lung fat embolism in a newborn infant?].

Lungs of 20 newborns were investigated microscopically after staining for fat substances. All lungs contained positive particles like small droplets of fat in vessels or aspirated fat in alveoli and fat in cells. Only in two cases of the group of living children were fat globuli observed in blood vessels which resembled morphologically a fat embolism of mild degree. It is discussed if these findings could be interpreted as a real traumatic fat embolism caused by birth injuries, a fat embolism that also is proving that a living child was born.

[Expert assessment of the blood alcohol value in traffic accidents].

100 written medical expertises of 14 medical experts concerning blood alcohol in court cases (traffic) were compared and analysed. Methods of calculations and results were different. It would be advisable if experts in Austria could reach a general agreement about their proceedings in determination of blood alcohol.

[Forensically important penis injuries].

Three cases with injuries of the penis are reported, 3 further cases are mentioned. These cases were 3 suicides, 2 cases, where the injury was inflicted by another person and 1 case with injury caused by a dog. Differential diagnosis is discussed.

[Euthanasia. A legal evaluation].

Passive euthanasia, but also active indirect euthanasia is under observation of some assumptions in Austrian law unpunished. To find the dogmatic arguments to exclude any liability there are several ways. The preference is given to that ways, which are paraphrased by positive law. Possible abuse of euthanasia should lead to a permanent discussion including other branches of science.

[Mechanism of action of forearm strangulation technics].

Two cases of death caused by the use of choke holds are reported; four different types of choke holds used in combative sports were investigated. In experiments on corpses it was found that even relatively little expenditure of strength can impede the passage of fluid not only through the internal carotid artery but also through the vertebral artery, depending on the respective choke hold. Fractures of the larynx cannot be expected as often as after typical throttling. However, a quick loss in defense capacity was found experimentally, and this always occurred within 15 s. Pulse frequency and blood pressure were recorded. Injuries to the neck are minor and may not be typical.

[Periventricular fatty metamorphosis in neuroglia--a morphologic substrate in SIDS].

In 7 of 15 cases of sudden infant death syndrome (SIDS), distinct periventricular fatty metamorphosis of the neuroglia could be demonstrated by a histological staining technique. None of the six children (under 1 year of age) used as a control group whose cause of death was not SIDS showed this morphological change. Thin-layer chromatographic analysis of the lipids accumulated in the glial cells in SIDS established a high amount of esterified cholesterol whereas the content of esterified cholesterol in the control group was low. We presume that fatty metamorphosis of the neuroglia represents the morphological substrate of a metabolic disorder of the sensitive, immature glia of the periventricular white cerebral matter caused by various kinds of damage.

[Liver rupture in a newborn infant caused by hemangiomatosis of the liver].

When a court-ordered autopsy was carried out on a deceased 17-day-old child, multinodular hemangiomatosis of the liver was determined to be the cause of massive intra-abdominal bleeding. The physicians who had treated the child had suspected this disease because of the results of their sonographic investigations, but were unable to reach a final diagnosis. Also, the results of the autopsy excluded negligence by the obstetricians with certainty.

Forensic problems in Rett syndrome.

A case of the Rett syndrome is presented, where the patient died without medical help at home because of extreme malnutrition. The forensic aspects of the case are discussed.

Poisoning with oral antiarrhythmic drugs.

The incidence of poisoning with antiarrhythmic drugs (AAD) is low, but frequently cardiac disturbances cause a high mortality. Clinical and toxicological data on verapamil, quinidine, ajmaline, prajmaliumbitartrate, mexiletine and aprindine as collected by the Austrian Poison Information Center (PIC) are presented in this paper. The drug concentrations of verapamil, mexiletine and quinidine detected in post-mortem specimens are discussed and compared with correspondent data from literature. Clinical experiences with this kind of intoxication are rather poor and therapeutical principles are very inconsistent. To avoid life-threatening symptoms, gastric lavage has to be performed irrespective of the latency period, accompanied by continuous cardiac monitoring. Cardiocirculatory disorders respond well to sympathomimetic drugs. Immediate and adequate cardiopulmonary resuscitation decisively determines the therapeutical success in critical cases.
