Unexpected Death Associated With Clostridial Sepsis.

An 85-year-old woman with a history of breast carcinoma presented to hospital after gradual onset of abdominal pain with hypotension, jaundice, and massive intravascular hemolysis. This was caused by Clostridium perfringens septicemia originating from a liver abscess. Clostridium perfringens septicemia is a rare infection that has a high mortality rate, given that it is frequently unable to be diagnosed until postmortem examination.

Actinomyces in Forensic Practice.

A 19-year-old woman in septic shock with recent computed tomography findings of a loculated hepatic abscess was transferred to an intensive care unit where she went into asystolic cardiac arrest. After resuscitation, surgical exploration revealed a purulent pericardial effusion with tamponade and a liver abscess. Microbiological analyses from both sites were negative.

Postmortem Tryptase Level in 120 Consecutive Nonanaphylactic Deaths: Establishing a Reference Range as <23 μg/L.

Postmortem tryptase is a useful biochemical test to aid the diagnosis of anaphylaxis. Multiple perimortem and postmortem factors have been documented to cause an elevation in postmortem tryptase level. One factor that was recently recognized to have an impact on postmortem tryptase level is correct sampling technique.

Evaluation of a model of bruising in pigmented skin for investigating the potential for alternate light source illumination to enhance the appearance of bruises by photography of visible and infrared light.

The purpose of this study was to evaluate the ability of alternate light source illumination to enhance bruises in pigmented skin. Previous work was limited to simulating bruises in non-pigmented (Caucasoid type) skin by injecting blood into pigskin. In this study, it was investigated if adding a layer of melanin to the surface of the skin would simulate pigmented skin.

Perinephric Fat Stranding on Postmortem Computed Tomography Scan in Acute Pyelonephritis: A Case Report.

Infection/inflammation of solid organ can be difficult to appreciate at postmortem computed tomography (CT) scan (PMCT). Perinephric fat stranding is a clinical CT finding to suggest pyelonephritis; however, PMCT scan showing perinephric fat stranding in acute pyelonephritis has not been documented in the forensic literature. We present a death from acute pyelonephritis in a setting of hypertensive heart disease, in which the unenhanced PMCT performed before postmortem examination was able to show florid bilateral perinephric fat stranding.

Systemic Dissemination of Injected Foreign Material.

A 32-year-old woman collapsed following an intravenous injection of material that included crushed pharmaceutical tablets. Resuscitation was attempted but was unsuccessful. She had an extensive past medical history of complications resulting from intravenous drug use.

Occult cardiac lymphoma and sudden death.

A 56-year-old man with no previous medical history collapsed and was not able to be resuscitated. The major findings at autopsy were enlargement of the heart (weight = 527 g) which contained an infiltrating firm, homogeneous tumor in an epicardial location adjacent to the left anterior descending and right coronary arteries, with further extension into the right ventricular outflow tract, the interventricular septum and left ventricular free wall. Sections showed sheets of small lymphoid cells with scattered large lymphocytes amounting to a low-grade follicular non-Hodgkin lymphoma, as tumor cells were CD20, CD10, Bcl 2 and LMO 2 positive.

Validation of alternate light sources for detection of bruises in non-embalmed and embalmed cadavers.

Bruising is frequently documented in cases of violence for use as forensic evidence. However, bruises can be overlooked if they are not visible to the naked eye. Alternate light sources such as ultraviolet, narrow band, and infrared have been used in an attempt to reveal the presence of bruising that is not otherwise apparent.

Validation of ultraviolet, infrared, and narrow band light alternate light sources for detection of bruises in a pigskin model.

Alternate light sources such as ultraviolet, narrow band, and infrared have been used in an attempt to reveal the presence of bruising that is not otherwise apparent (inapparent). The following study evaluates the ability of alternate light sources to enhance visibility of bruises by employing an objective assessment of digital photography images in conjunction with histology. A pigskin model was employed with bruises created by injection of blood to be not visible or barely visible (inapparent) under white light.

Injury patterns and features of cycling fatalities in South Australia.

There has been an increase in cycling in Australia. This means that more cyclists are at risk of injuries, which account for a proportion of transport-related fatalities. In this study, all cyclist fatalities from 2002 to 2013 in South Australia where post-mortem examinations were performed were investigated.

Injuries associated with resuscitation - An overview.

External cardiopulmonary resuscitation is a potentially lifesaving intervention aimed at preserving the cerebral function of a person in cardiac arrest. However, certain injuries can be caused by the various techniques employed. Although these are seldom consequential, they may complicate the forensic evaluation of cases.

Heme oxygenase-1 and heme oxygenase-2 expression in bruises.

The first step in catabolism of hemoglobin in a bruise is performed by the enzyme heme oxygenase, which produces biliverdin that is then reduced to bilirubin. The development of yellow coloration in bruises can be attributed to local accumulation of degradation products of hemoglobin, including bilirubin, but it is not clear why there is a delay before this color change is apparent. One explanation may be that time is required for the establishment of heme oxygenase activity at the bruise site.

Female productivity and mortality in early-20th-century Taiwan.

In late-Qing-dynasty Taiwan (1870-1895), female infanticide and general neglect killed over 15% of young girls. During the early years of Japanese rule (1895-1915), female infanticide was almost completely eliminated and the treatment of girls improved. This paper argues that the increase in the willingness to raise daughters was due to an increase in adult female productivity.

The biological standard of living in Taiwan under Japanese occupation.

This paper presents evidence on the biological standard of living in Taiwan from 1842 to 1931 using Taiwanese height and weight data collected by the Japanese authorities from 1921 to 1931. This study shows that in the late Ch'ing adult heights were not increasing over time, while the adult heights of those born after the Japanese takeover did begin to increase rapidly. Evidence from children's heights confirms that this growth in height continued through the 1920s.
