Massive Blunt Trauma Research Articles

Death scene investigation and autopsy proceedings in identifying the victims of the terror attack on the Breitscheidplatz in Berlin 19th December 2016

We describe and discuss the forensic mission after the terrorist attack on the Breitscheidplatz in Berlin on 19th December 2016, focusing on co-operation with police authorities, and the injury patterns of the deceased. Even after massive blunt trauma, severe injury patterns are often unrecognizable by visual inspection of the body (“Casper’s sign”), which could instill false security among rescuers or, as happened on the Breitscheidplatz, may lead to distress or even trauma in rescue personnel when obviously primarily uninjured patients die suddenly.

Pancreatico duodenectomy for pediatric combined duodenal, pancreatic and biliary trauma

Pancreaticoduodenal trauma in children is uncommon but carries high morbidity and mortality rates, especially when the diagnosis is delayed. A case of combined pancreatico duodenal and bile duct injury following blunt abdominal trauma is described which presented two days after injury. It highlights the extremes of surgical procedures that may be needed in massive blunt trauma.

The use of forearm free fillet flap in traumatic upper extremity amputations

Complete traumatic upper extremity avulsions are an infrequent but devastating injury. These injuries are usually the result of massive blunt trauma to the upper limb. Intact issue from amputated or nonsalvageable limbs may be transferred for reconstruction of complex defects resulting from trauma when the indications for replantation are not met. This strategy allows preservation of stump length or coverage of exposed joints, and provides free flap harvest for reconstruction without additional donor-site morbidity. A retrospective review at São João Hospital was performed on seven patients who had undergone immediate reconstruction with forearm free fillet flaps between 1992 and 2007. There were six men and one woman, with patient age ranging from 17 to 74 years (mean, 41 years). Amputation sites were at the humeral neck (n = 1), at the humeral shaft (n = 5), and below the elbow (n = 1). The area of the forearm free fillet flap skin paddle was 352.14 +/- 145.48 cm (mean +/- SD). The two major complications were the flap loss and the patient death on postoperative day 3 in other case. The postoperative course in the remaining five cases was uneventful with good healing of the wounds. Minor complications included two small residual defects treated by split-thickness skin grafting and one wound infection requiring drainage and revision. The forearm free fillet flap harvested from the amputated limb provides reliable and robust tissue for reconstruction of large defects of the residual limb without additional donor-site morbidity. Microsurgical free fillet flap transfer to amputation sites is valuable for achieving wound closure, improving stump durability, and maximizing function via preservation of length.

A Decade of Train-Pedestrian Fatalities: The Charleston Experience

Although the cause of death is rarely in doubt in train-pedestrian fatalities, the manner of death is often unclear. The distinction between accident and suicide can only be made after careful evaluation of the history, scene investigation, autopsy findings, and toxicologic data. A retrospective analysis of 25 consecutive train-pedestrian fatalities investigated by our office between 1982 and 1992 is reported. The victims were predominantly healthy, young males. All but one person died at the scene. The cause of death was massive blunt trauma in 88% of the cases. In one case, the sole injury was decapitation. A tissue or blood ethanol level greater than 99 mg/dL was detected in 80% of the cases. A total of 60% of the cases involved persons likely to have been sitting or lying across the railroad tracks; all but one of these victims were intoxicated. The manner of death was determined to be accidental in 92% of our cases. Decapitation by a moving train is an injury highly suggestive of suicide. Massive blunt trauma, especially in the setting of ethanol intoxication, was highly associated with accidental death. Toxicologic analysis is essential in discriminating willful suicide from alcohol-induced incapacitation resulting in accidental death. Homicide, disguised as an accident or suicide, must be ruled out in all cases. Accurate determination of the manner of death is an important issue regarding civil litigation and dispersal of insurance benefits.

Freisetzung von Proteinase-Inhibitoren als vitale Reaktion im fr�hen posttraumatischen Intervall

In a pilot study paraffin-embedded sections of open skin wounds (stab and slash wounds, lacerations) were investigated to determine the presence of a vital reaction. Granulocytes were detected by naphthol AS-D chloroacetate esterase, the enzyme "lysozyme", and eight proteinase inhibitors by the indirect immunoperoxidase method. The tissue specimens were taken from consecutive autopsy material. The survival time could be determined in 14 cases (10-165 min) and was unknown in 12 other cases of sudden death due to injury of the major vessels or heart. The controls were cases with injuries inflicted after and cases of sudden death due to massive blunt trauma served death. In vital injuries, accumulations of proteinase inhibitors, particularly alpha-2-macroglobulin and alpha-1-antichymotrypsin, were demonstrable in the corium parallel to the wound surface. In comparison, the reaction of proteinase inhibitors that neutralize only enzymes participating in blood coagulation or complement activation (C1-esterase inhibitor and protein C) was absent or weak. Protein accumulation was observed only sporadically in cases of sudden death and never in cases with wounds inflicted after death. No relationship could be established between semiquantitatively estimated staining and survival time. Granulocytes and lysozyme were first observed in the corium after a survival time of more than 60 min.
