Hypothermic sepsis in time since death estimation - a case report.

Both hyper- and hypothermia are problematic in temperature based forensic time since death estimation. Hyperthermia may occur in infection, traumatic brain injury, and intoxication. Hypothermia is encountered predominantly in exposure.

"Scalping" in the context of criminal dismemberment and mutilation-a case report and review of the literature.

We report on a case of criminal dismemberment and attempted scalping of a homicide victim with a "Mohawk" haircut. Case findings are presented. A review of the literature was performed for scalping in its historical and cultural context and particularly in criminal dismemberment and mutilation: Historically, scalping was prevalent in many ancient cultures around the world, where scalps were taken as trophies or "proof of kill", much like shrunken heads, trophy skulls, and other artefacts.

Are the (New) Synthetic Opioids U-47700, Tramadol and Their Main Metabolites Prone to Time-Dependent Postmortem Redistribution?-A Systematic Study Using an In Vivo Pig Model.

The interpretation of analytical results in forensic postmortem (PM) cases often poses a great challenge, in particular, due to possible PM redistribution (PMR) phenomena. In terms of new synthetic opioids, such data are usually not available and, if so, they are from case reports without the exact knowledge of dose, user habits, time of consumption or PM interval (PMI). Hence, a controlled toxicokinetic pig study was performed allowing the examination of PM tissue distribution and possible PMR of U-47700, tramadol and the main metabolites N-desmethyl-U-47700 and O-desmethyltramadol (ODT).

Body-kun/body-chan style model figures for artists in forensic visualization applications.

Posture and body position are often in the focus of forensic medicine. Visualization for the purposes of documentation, teaching, scientific presentation or expert opinion in court is often desired. Plenty of possible tools to support visualization are available.

Perimortem Distribution of U-47700, Tramadol and Their Main Metabolites in Pigs Following Intravenous Administration.

In spite of a decreasing number of new releases, new synthetic opioids (NSOs) are gaining increasing importance in postmortem (PM) forensic toxicology. For the interpretation of analytical results, toxicokinetic (TK) data, e.g.

Application of the "bubbling" procedure to dead body portraits in forensic identification.

Purpose: A procedure is needed for bodies with disfiguring injuries to the face and the use of their portrait for visual identification.

Method: We present the application of a simple image processing procedure, otherwise known as "bubbling," which is based on the concept of "perceptual filling-in," to images for visual identification in the forensic context. The method is straight forward and can be performed using readily available software and hardware.

Relative blood loss in forensic medicine-do we need a change in doctrine?

Unlabelled: In forensic medicine, blood loss is encountered frequently, either as a cause of death or as a contributing factor. Here, risk to life and lethality assessment is based on the concept of relative blood loss (absolute loss out of total volume). In emergency medicine, the Advanced Trauma Life Support (ATLSⓇ) classification also refers to relative blood loss.

Time since death nomographs implementing the nomogram, body weight adjusted correction factors, metric and imperial measurements.

The concept of nomography was developed around 1880 as a means to compute formulas graphically. Regular use has decreased over time in most fields, mainly owing to progress in electronic computation devices. In forensic pathology, nomography is still used in the so-called "nomogram method" for the estimation of time since death.

Analysis of laryngeal fractures in decomposed bodies using microfocus computed tomography (mfCT).

Postmortem computed tomography (CT) is now routinely performed in forensic autopsies. Microfocus computed tomography (mfCT) has attracted recent attention because it can provide more detailed information than routine postmortem CT can. This feasibility study evaluated the usefulness of mfCT for examination of the hyoid bone and thyroid cartilage in cases of suspected strangulation, where advanced decomposition precludes detection of petechial hemorrhages and hemorrhages adjacent to fractures.

Blunt force impact to the head using a teeball bat: systematic comparison of physical and finite element modeling.

Blunt head trauma secondary to violent actions with various weapons is frequently a cause of injury in forensic casework; differing striking tools have varying degrees of injury capacity. The systematic approach used to examine a 19-year-old student who was beaten with a wooden teeball bat will be described. The assailant stopped beating the student when the teeball bat broke into two pieces.

Drying properties of bloodstains on common indoor surfaces.

When blood reaches an extracorporeal surface, a drying process is initiated. Properties of this drying process may be crucial for the correct assessment of case-specific time lapses, however, there is a lack of systematic studies concerning the drying times of blood. We present a study on drying properties of small blood droplets with a standardized size of 25 μl (resembling droplets originating from pointed and sharp objects, e.

Ultra-low dose dual-source high-pitch computed tomography of the paranasal sinus: diagnostic sensitivity and radiation dose.

Background: Today's gold standard for diagnostic imaging of inflammatory diseases of the paranasal sinus is computed tomography (CT).

Purpose: To evaluate diagnostic sensitivity and radiation dose of an ultra-low dose dual-source CT technique.

Material And Methods: Paranasal sinuses of 14 cadaveric heads were independently evaluated by two readers using a modern dual-source CT with lowest reasonable dosage in high-pitch mode (100 kV, 10 mAs, collimation 0.

Reverse engineering--rapid prototyping of the skull in forensic trauma analysis.

Rapid prototyping (RP) comprises a variety of automated manufacturing techniques such as selective laser sintering (SLS), stereolithography, and three-dimensional printing (3DP), which use virtual 3D data sets to fabricate solid forms in a layer-by-layer technique. Despite a growing demand for (virtual) reconstruction models in daily forensic casework, maceration of the skull is frequently assigned to ensure haptic evidence presentation in the courtroom. Owing to the progress in the field of forensic radiology, 3D data sets of relevant cases are usually available to the forensic expert.

The deployment of conditional probability distributions for death time estimation.

The temperature based algorithm known as the Nomogram Method for the determination of a 95.45% death-time interval can be combined with non-temperature based (NTB) findings in the so called Compound Method (CM). The impact of such integration on the probability yielded by the resulting interval has however neither been described nor exploited.
