Postmortem radiological investigation of bridging vein ruptures.

In the usual method of brain removal in forensic autopsies, the upper bridging veins were invariably torn. There are several types of head injuries, in which ruptures of these vessels are the predominant intracranial injury. For the past 5 years we have investigated nearly all cases of lethal head injuries by a simple X-ray method (axial X-ray after instillation of contrast material into the superior sagittal sinus). The evaluation of the 350 X-rays which were available until today can be summarized by the following statements. (a) Anatomy of the parasagittal bridging veins: regarding the numbers and diameters of the veins, we can separate cases with many bridging veins of small diameter from a group with few veins of a large diameter. (b) Causes of injury and direction of impact: bridging vein ruptures resulted more often from frontal than from occipital, parietal and lateral impacts and occurred in traffic accidents in the majority of our cases.

Bone finds: a challenge to forensic science.

The study presented here is based on 176 forensic dental reports compiled between 1993 and 2001. The bulk of the research took place in 1997, when major construction at Potsdamer Platz and Lehrter Bahnhof in central Berlin required the excavation of considerable quantities of earth. As building proceeded here, at 'Europe's biggest construction site', it revealed not only a large number of long bones, but also a great many skulls and skull fragments. In five instances, complete skeletons were unearthed. Many of the bones ultimately proved to be of animal origin. The police were not instructed to open a single criminal investigation. Identifying and piecing together the material in this context makes tremendous demands of forensic osteology. Establishing the nature of these finds beyond reasonable doubt, and putting a name and date to them, calls for interdisciplinary co-operation between experts in odontology, anthropology, anatomy, radiology and veterinary medicine, not to mention historians.

Forensic importance of aspiration.

The problems of assessment of aspiration (foreign bodies, stomach contents, food material) in forensic practical work are well-known, especially if 'suffocation due to aspiration' is considered to be the cause of death (or a concurrent cause of death). In the last 4 years (1998-2001) in the Department of Legal Medicine of the Free University, Berlin, 14 deaths with massive aspirations were investigated. The lethal aspiration cases consisted of seven men and five women between 55 and 91 years old, as well as two children (boy 6 years and girl 19 months old). All but one of the victims had severe neurological alterations (dementia, apoplexia, sequelae of head injuries). In six cases the victims died during or a short time after a meal; they had been fed by the nursing staff, a family member or another caregiver. The witness statements pertaining to clinical symptoms or the course of events ranged from 'no symptoms' to intensive cyanosis, congestion and no clear reactions of distress.

External injury marks (wounds) on the head in different types of blunt trauma in an autopsy series.

The localization, length and number of deep scalp wounds caused by falls on a flat surface (n = 203), falls down stairs (n = 51) and from blows (n = 51) were examined in a comparative analysis of 305 deaths. This confirmed the common finding in forensic literature that head injuries from blows occur more often (55% of cases) above the so-called hat-brim line (= greatest horizontal head circumference) than injuries from falls on a flat surface. On the other hand, around one third of the wounds caused by falls were located above this line. In blows and falls down stairs, but not in falls on a flat surface, the wounds close to the crown of the head were markedly longer than those in or below the hat-brim line. Regarding wounds inside the hat-brim line, there were hardly any differences between the three trauma types.
