The current trend towards the implementation of organic gunshot residue (OGSR) analysis into gunshot residue (GSR) investigation protocols typically involves the sequential analysis of inorganic and organic GSR. However, to allow for the consecutive analysis of inorganic and organic GSR, specimens will often be stored for different lengths of time which may result in compounds of interest degrading. In order to optimise storage conditions, it is important to consider compound degradation on collection devices during storage...

An accurate and precise documentation of injuries is fundamental in a forensic pathological context. Photographs and manual measurements are taken of all injuries during autopsies, but ordinary photography projects a 3D wound on a 2D space. Using technologies such as photogrammetry, it is possible to create 3D detailed, to-scale, true-color documentation of skin injuries from 2D pictures. A comparison between the measurements of 165 lesions taken during autopsies and on photogrammetrically processed pictures was performed...

To investigate if there is any correlation between the bullet design and the respective dimensions of the abrasion collar and the skin defect in gunshot entrance wounds, experimental studies were performed on dyed pig skin. For the test shots, .38 Special revolver cartridges with three different bullet designs (round nose, wadcutter, and truncated cone) were used. With the help of an image editing program in combination with an image analyzing system, the area size of the abrasion rings and the skin defects was calculated automatically...

Penetrating neck trauma is most commonly caused by firearm discharge, and is potentially very dangerous, being associated with a high risk of mortality. A 12-year-old patient with a recent history of a gunshot wound to the neck was evaluated in detail; a bullet was located in close proximity to the left common carotid artery. Neck exploration was performed and the foreign body was removed without any complications. The management of the patient is discussed, as are contemporary approaches to the treatment of penetrating neck trauma...

The traces produced when a firearm is discharged can provide important information in cases when questions regarding a possible association of the firearm with a person of interest (POI), time since discharge or shooting distance are raised. With advances in technology, the forensic challenges presented by these traces, known as gunshot residues (GSR), are moving from the analytical domain to the interpretation of the analytical results. Different interpretation frameworks are currently competing. Formal classification of particles, using standards such as that produced by ASTM, focusses only on evaluation of evidence at the sub-source level...

BACKGROUND: In penetrating thoracoabdominal trauma, it is necessary to evaluate both the pericardial fluid and the diaphragm directly. Transdiaphragmatic pericardial windows (TDWs) provide direct access to the pericardium and diaphragm but expose the patient to the risks of laparotomy. We hypothesize that transabdominal laparoscopic pericardial windows (LPWs) are a safe and effective alternative to TDWs in stable patients. METHODS: This is a retrospective observational study of stable patients with thoracoabdominal penetrating trauma at a level I trauma center between January 2007 and June 2015, comparing outcomes after TDW versus LPW...

Simultaneous determination of nitrate and nitrite in gunshot residue has been conducted by capillary electrophoresis using an acidic run buffer (pH 3.5). In previously developed capillary electrophoretic methods, alkaline pH separation buffers were used where nitrite and nitrate possess similar electrophoretic mobility. In this study, the electroosmotic flow has been reversed by using low pH running buffer without any additives. As a result of reversing the electroosmotic flow, very fast analysis has been actualized, well-defined and separated ion peaks emerge in less than 4 min...

BACKGROUND: Cerebral gunshot wounds represent one of the most lethal forms of traumatic brain injury, but there is a paucity of literature on the topic, especially from the developing world. We reviewed our experience and describe the spectrum and outcome of civilian cerebral gunshot wounds in a major metropolitan trauma centre in South Africa. METHODS: This was a retrospective study of all patients with isolated cerebral gunshot wounds managed by the Pietermaritzburg Metropolitan Trauma Service over a 5-year period from 2010 to 2014...

If police officers are contaminated with gunshot residue (GSR) through the normal receiving, checking, loading, and securing of their issued firearm, there is the potential for secondary transfer of GSR to anyone those officers arrest during their shift. This 3-part study examined the level of GSR contamination of police officers following the start-of-shift handling of their standard issue firearm, the impact that hand-washing or the use of a self-drying hand-wash had on the level of GSR contamination, and the likelihood of officers re-contaminating their hands through contact with the exposed hand-grip of their holstered hand-gun...

INTRODUCTION: Diagnostic laparoscopy is well accepted in the management of penetrating abdominal trauma (PAT). Therapeutic laparoscopy, on the other hand, remains controversial. In patients with multiple hollow viscera injuries, laparoscopy is usually converted to laparotomy. We aim at describing the laparoscopic-assisted technique in the management of patients with PAT. Using our experience with laparoscopy, we tailored the technique to the setting of PAT. METHODS: The laparoscopic-assisted approach (LAA) was adapted to a trauma setting and prospectively evaluated...

We describe a unique case of orbital gunshot injury with isolated intraorbital pellets lodged symmetrically in the two apices, causing identical clinical presentation, and absence of any associated globe or cerebral injury. He developed bilateral complete third nerve palsy with bilateral traumatic optic neuropathy. The optic nerve strut prevented the pellets from going into the brain on both the sides.

Atypical gunshot wounds present a challenge for the forensic expert, and sometimes differentiating these from a blunt trauma can be difficult. A careful crime scene investigation can be helpful in finding additional evidence and clarifying the nature of the injuries. We describe a case of an unusual craniocerebral injury that was initially interpreted as a blow from a wooden object. The appearance of the wound lacked the classical characteristics of entrance and exit bullet wounds, but the investigation showed it was due to the ricocheting of a destabilized bullet...

BACKGROUND: Vitamin D depletion has been associated with increased rate of infections, lengthened hospital stay, and worsened mortality for critically ill patients. The purpose of this study was to evaluate the prevalence and variables associated with vitamin D deficiency in critically ill patients with severe traumatic injuries. METHODS: Critically ill adult patients admitted to the trauma intensive care unit (ICU) between June 2013 and June 2014, referred to the nutrition support service for enteral or parenteral nutrition, and had a serum 25-hydroxyvitamin D (25-OH vitamin D) concentration determination were retrospectively evaluated...

A 29-year-old man arrived in our emergency department after being shot on the face. Computed tomography (CT) revealed multiple facial bone fractures along the bullet trajectory. On day 10 of admission, CT angiogram of the neck revealed a partially thrombosed pseudoaneurysm in the parapharyngeal fat pad. The pseudoaneurysm was successfully treated with coil embolization. This report discusses diagnosis and treatment of a partially thrombosed internal maxillary artery pseudoaneurysm. Although digital subtraction angiography is the gold standard for pseudoaneurysm diagnosis, CT angiography may provide complimentary information, as seen in this case...
