摘要:

A review of the literature on perforation of skin by bullets and missiles indicates that there is a range of velocity below which a missile cannot perforate the skin. Velocities of between 38.1 and 61.6 meters/second (125 and 202 ft./second) will produce at least minimal damage to the surface of the skin, though without perforation. In order for a missile to perforate the skin and enter the underlying subcutaneous tissue and muscle, a minimum velocity in the order of 70 meters/second (230 ft./second) is necessary with an energy/area of presentation of approximately 2.1 m-kg/cm2.

摘要:

A wound caused by an exploder bullet should be suspected in the presence of a primer anvil, percussion cap, or multiple lead fragments from a low-velocity bullet not striking bone. The autopsy may reveal a larger area of tissue destruction at the site of the bullet exploding than would be expected from simple passage of an intact projectile.

摘要:

Microscopic hemorrhages in the brain stem were studied in cases of known head injury and in cases where head injury was known not to have occurred. They were found to be either strictly limited to the perivascular space or to extend into the neuropil. Those limited to the perivascular space appear to be artifacts and should not be considered when determining the cause of death. Extravasations of red cells into the neuropil may be of traumatic genesis. Such hemorrhages may be absent, however, in cases of a fatal primary brain-stem injury.

摘要:

Abnormal central neural regulation of respiration may be involved in the pathogenesis of the sudden infant death syndrome (SIDS). A retrospective investigation of brain-stem morphology in 34 SIDS victims compared to well-matched controls revealed medullary gliosis in the reticular formation in 12% and a single microglial nodule suggestive of a viral infection in one infant. These findings support the need for more extensive prospective neuropathological investigations in SIDS utilizing more sophisticated techniques.

摘要:

A case of sudden and unexpected death due to idiopathic cardiomyopathy of hypertrophic type in a 50-year-old man is reported. The heart showed on gross observation a very marked hypertrophy (1100 g); microscopically, muscle fibers were different in size and shape, with hypertrophy of nuclei, associated with a moderate increase of connective tissue.

摘要:

A postmortem examination early during the investigative period of the murder of a young law enforcement officer on the edge of the Kansas Turnpike led to the development and application of a technique for the preservation of evidence by a visiting consultant. This resulted in the construction of a life-sized head which was used to demonstrate the entrance and exit sites of two bullets through the head and the site of the injury to the head from a pistol butt. This exhibit provided a dynamic demonstration of the relationship of the fatal weapon to the victim and contributed to the understanding of the paths of the bullets which passed through the victim's head into the ground. The technique is described.

摘要:

Sporadic deaths from Legionnaires' disease may escape detection at autopsy. Known epidemiological and clinical features of the disease should arouse suspicion and prompt appropriate bacteriological studies. The pathological findings in Legionnaires' disease are almost entirely confined to the lungs and are not distinct from any other severe bacterial bronchopneumonia. The causative organism, Legionella pneumophila, is difficult to identify on a Gram stain but will stain nonspecifically with the Giemsa, Warthin-Starry, and Dieterle techniques. The direct fluorescent antibody method allows specific identification of Legionella in paraffin-embedded tissue sections.

摘要:

This analysis of fatal blood transfusion reactions includes statistics from the Bureau of Biologies provided through the Freedom of Information Act. The study of 126 reported transfusion fatalities occurring between 1976 and 1980 showed that the staff certifying compatibility and the personnel administering the blood have an approximately equal share of the problems. Resolution of blood bag labeling errors through automation leaves patient identification as a major obstacle to those certifying compatibility and the transfusionists. The patient identification wrist band is excellent. However, professional staff do not always utilize this information, relying on memory. In addition, professional staff do not always collate adequately the information on the blood transfusion request form, the blood bag label, and the wrist band of the patient to be transfused. Electronic collation is discussed as a means to identify discrepancies prior to transfusion. The special problem of staff dealing with a time-limited, life-threatening emergency is described and six critical areas related to the problem of fatal transfusion reactions are suggested for further analysis.
