A mystery: One wound, multiple bullets

This case report provides an unusual presentation of a gunshot wound (GSW) and stresses the importance of gathering complete clinical, scene and historical information, if possible. Sufficient details regarding an injured patient’s mechanism of injury (MOI) should be elicited by the treating physician when hemodynamic status of the patient allows. A careful physical exam is essential as are appropriate laboratory investigations and diagnostic imaging. We present a case report of a single GSW found on physical exam with multiple projectiles found on imaging studies. The history of present illness, scene findings and trial transcripts clarify the patient presentation.

Management of Rare Shot Wounds of the Skull Base

Shot wounds of the face and the skull base are rare in German clinics. Thus the clinical experiences with these special injury samples are very small. It is possible to make a distinction between injuries from single projectiles and from multiple projectiles of a shooting with pellets. While projectile injuries were particularly discussed in the military medical literature, there are almost no empiric reports about the treatment of injuries caused by shooting with pellets.

Production of helium projectile fragments in 16 O–emulsion interactions at 4.5 A GeV/ c

The measurements of partial production cross sections of the multiple helium projectile fragments emitted at 4.5 A GeV/c 16O–Em interactions are reported. We have studied the production rate of helium projectile fragments due to fragmentation of 16O ions and compared it with that obtained from different projectiles at various energies. The dependence of on the mass number of the incident beams is formulated. The multiplicity distributions of the helium fragments produced in 16O–Em interactions at different energies exhibit Koba–Nielson–Olesen (KNO) scaling. The correlation of helium projectile fragments and target fragments is also investigated and it is found that the average of target fragments is increased with the decrease of the number of helium fragments in peripheral interactions.

Planned Complex Suicide by Self-Poisoning and a Manipulated Blank Revolver: Remarkable Findings Due to Multiple Gunshot Wounds and Self-Made Wooden Projectiles

A remarkable case of complex suicide with poisoning and multiple self-inflicted gunshot wounds to the head is reported. After ingestion of a liquid insecticide, the victim shot himself twice in the head, once in each temple. Self-manufactured wooden dowels were used as projectiles in combination with conventional blank cartridges. The dowels had been glued on top of the blank cartridges and expelled by propellant gases. Moreover, the blank revolver used had been extensively manipulated in a rarely observed manner. Several occlusive devices had been removed from the barrel and the cylinder chamber to enable the expulsion of the wooden projectiles. The investigation of the methods used and the circumstances found at the scene pointed towards a planned complex suicide. A remarkable case with unusual projectiles, i.e., wooden dowels, fired by an extensively manipulated blank gun is reported, emphasizing the importance of close collaboration between the police firearm laboratory and forensic pathology in practical casework.

Strong evidence for enhanced multiple electron capture from surfaces in 46 MeV/u Pb81+ collisions with thin carbon foils.

Strong evidence has been found for enhanced multiple electron capture into 46 MeV/u Pb81+ with a significant contribution from the entrance surface of thin carbon foils. Capture of up to five electrons has been observed. The multiple electron capture yield is found to increase with decreasing target thickness for thin targets. A simple model describing the data and showing the importance of capture from surfaces is discussed. Further evidence is found for a pronounced asymmetry between electron capture at the entrance and the exit surfaces. Absolute yields for multiple electron capture and projectile ionization are presented. The experimental total cross sections for single capture and ionization agree well with theory.

Energy requirements for the penetration of heads of domestic stock and the development of a multiple projectile.

The forces and kinetic energy required to penetrate the isolated heads of calves, adult beef cattle, sheep and red deer with a metal probe the same diameter as the bore of an experimental pistol were determined. Approximately 16 and 127 Joules were required to penetrate the heads of adult sheep and cattle, respectively. Using these data a 10 g projectile, consisting of 49 lead pellets and a lead disc in a polyethylene sleeve, was constructed. This projectile, when fired by a charge sufficient to produce a muzzle velocity of 165 m/second, had sufficient kinetic energy to penetrate the heads and brains of cattle, sheep, horses and deer. The projectile was fired from a new design of humane killer with a spring loaded barrel and fitted with a silencer. After penetration of the frontal bones the projectile fragmented and the kinetic energy of its individual particles were insufficient for them to penetrate the opposite side of the head of any of the animals, including one-week-old calves. Fragmentation also caused more brain damage and inhibition of spinal reflexes than a solid free bullet or captive bolt. It is suggested that the use of such a projectile for the emergency slaughter of animals is less hazardous than a solid free bullet and is easier to use and more effective than either a solid free bullet or captive bolt. The projectile was not suitable for killing adult pigs because of problems associated with the frontal sinus.

Multiple projectile injuries

A case of projectile injuries secondary to lawn edger use is presented. A 32-year-old man was seen in the emergency department with the complaint of bilateral shoulder pain and initially without a history of trauma. When small scars were noted at the sites of pain, a history was elicited of possible injury six months previously while using a gasoline-powered lawn edger. Radiographic evaluation revealed bilateral wire missiles embedded in soft tissue. These were later removed uneventfully.
