Site of discovery in the bath tub. Evaluation of a fatality after four years using postmortem roentgen diagnosis]

On the one hand the following case demonstrates the problems of finding a dead body in the bathroom and on the other hand the importance of postmortem x-ray examinations. The corpse of an 65-year-old woman was discovered in her bath tub. At the body's feet there was a hair dryer. Investigations concerning murder were negative, circumstances appeared to be unsuspicious. That was why a postmortem examination was not performed. -4 years later murder had to be considered. After manual strangling the deceased and the hair dryer were layed into the bath tub. The corpse was exhumed and taken to a forensic autopsy. It was found that the hyoid bone and the superior horn of the thyroid cartilage were both fractured on the right. Damages caused by the preparation itself were excluded by using serial roentgenographs. These observations in combination with histological findings and the results of further investigations convincingly supported the suspicion of strangling by hand.     

G3M T typing by dot immunobinding with monoclonal anti-G3M T antibody

Dilutions of 100 serum samples of various GM phenotypes were dotted onto a nitrocellulose membrane. The serum dot-blots were detected with peroxidase-labeled anti-G3M T monoclonal antibody (anti-G3M T MAb). Up to a 1 : 256 dilution could be G3M T-typed correctly. By use of anti-G3M T MAb and peroxidase-labeled anti-mouse IgG or the biotin-avidin system instead of use of labeled anti-G3M T MAb, up to a 1 : 512 or 1 : 1024, respectively, dilution was typable. As with previous work with G3M G MAb, the dot immunobinding (DIB) method for G3M T typing was found very simple and practical.     

Sulfide concentrations in postmortem mammalian tissues

Postmortem changes in sulfide concentrations in body tissues were examined in autopsied rats exposed to hydrogen sulfide concentrations of 550 to 650 ppm, and in nonexposed rats and humans. Analyses were made by gas chromatography, following an extractive alkylation. Sulfide concentrations in the blood, liver, and kidneys of rats increased in both the exposed and nonexposed groups, depending on the lapse of time after death. On the other hand, the lung, brain, and muscle showed little or no change in sulfide concentration with elapse of time after death. The data obtained from human tissues were almost the same as those for rats, except data for blood, in which no or little increase of sulfide was observed.     

The use of either the nose or outer ear as a means of determining the postmortem period of a human corpse.

Presented in this paper are the initial results involving the use of the nose or outer ear as temperature measurement sites to determine the postmortem period of the human corpse. Simple mathematical models for both sites are developed based on cooling curves of five corpses. Analysis of errors between actual and calculated postmortem intervals suggest that in its present form, the described methods would not be suitable for use in accurately determining the time since death of human corpses.     

Dissecting intramural haematoma of the coronary artery with intimal tears.

A dissecting intramural haematoma of the coronary artery is an infrequent cause of sudden and unexpected death. Most cases are women and in a significant number of these women, the haematoma occurred at term to 80 days postpartum. Because the intimal rupture and communication with the lumen were not found in most of the cases, the site of rupture has been considered to be a vasa vasorum. The authors report on a case of one woman who was at a later postpartum period (106 days). The microscopic finding of the dissected coronary artery revealed two intimal tears in a section. The case showed that the dissecting intramural haematoma of the coronary artery is caused not only by the rupture of the vasa vasorum but also by the rupture of the intima.     

Identification based on medical findings

1. The indications such as the place of finding, the identification of clothes or other personal items, represent only the first step towards the identification of a corpse. 2. An identification based on medical data, other than dental, is often possible, more often than it is believed. 3. The forensic pathologist plays a double role in the case of such an identification: a) in the phase of the inquiry, he must contact the investigators and the families to explain his wishes and the different possibilities of identification. b) he must use the gathered information in the appropriate way. 4. It would be desirable to compose some statistical tables of the various medical elements useful for the identification (mutilations, surgical operations, etc...). We present six cases of identification in our practice.
