Porcine tissue samples shot with two different types of bullets, jacketed and nonjacketed, were collected in the fresh state and throughout moderate decomposition. Wound samples were microwave-digested and analyzed using inductively coupled plasma mass spectrometry (ICP-MS) to detect all elements present at measurable levels in gunshot residue (GSR). Elements detected included antimony (Sb), ba...

A concise and factual abstract is required. The abstract should state briefly the purpose of theresearch, the principal results and major conclusions. An abstract is often presented separately fromthe article, so it must be able to stand alone. For this reason, References should be avoided, but ifessential, then cite the author(s) and year(s). Also, non-standard or uncommon abbr...

Penetrating cardiac injuries after gunshot are usually fatal and are very challenging to manage for surgeons even in fully- equipped centres. Such injuries can cause ventricular septal defect (VSD) or cardiac tamponade depending upon the distance, direction and velocity of the bullet. Stable patients can be subjected to investigations like computed tomography (CT) to avoid unnecessary intervent...

Cauda equina syndrome (CES) is a serious neurological condition and the most common cause is a central disc herniation. Migration of a bullet down the spinal canal is uncommon. In this report, the authors present an unusual case of cauda equina syndrome caused by a migrated bullet in dural sac. The patient's cauda equina syndrome was related to possible compression of cauda equina resulting fro...

Spontaneous migration of retained bullets in the brain is a recognized rare complication of penetrating cranial gunshot wounds to the brain. The authors report one rare case in a 55-year old male patient who presented with a penetrating cranial gunshot wound and a retained bullet. He had a dense right hemiplegia and expressive aphasia on admission. Skull x-ray confirmed the retained intracrania...

We present a collision detection and force computation algorithm based on the Voxelmap-Pointshell Algorithm which was integrated and evaluated in the physics engine Bullet. Our algorithm uses signed distance fields and point-sphere trees and it is able to compute collision forces between arbitrary complex shapes at simulation frequencies smaller than 1 msec. Utilizing sphere hierarchies, we are...

Plasma plumes with exotically segmented channel structure and plasma bullet propagation are produced in atmospheric plasma jets. This is achieved by tailoring interruptions of a continuous DC power supply over the time scales of lifetimes of residual electrons produced by the preceding discharge phase. These phenomena are explained by studying the plasma dynamics using nanosecond-precision imag...

CONTEXT A pancreatic fistula is the most common complication of pancreatic injury. Although spontaneous closure of pancreatic ductal disruption has been reported, surgical treatment is accepted as the single most carried-out intervention in major ductal injury. We report a case of pancreatic duct disruption due to a bullet injury managed successfully by endoscopic pancreatic duct stenting. CA...

The vertebral artery (VA) is well protected through its course at the cervical transverse foramina and penetrating injuries of VA are mostly caused by gun shot wounds. The mechanism of injury in these wounds is described as the kinetic energy transferred by the bullet, which always depends on its mass and speed. Thus, the size of the pellet is the most important factor for the tissue damage, sh...

Lead toxicity from a retained bullet as a cause for abdominal pain is rarely considered. Given its unpredictable latent period and nonspecific clinical symptoms, such cases are difficult to diagnose but may be fatal if unrecognized. We present the case of a 48-year-old man who presented with complaints of abdominal pain, weight loss and constipation. His past history was significant for a gunsh...
