Asphyxial death during prone restraint revisited: a report of 21 cases

Determining the cause of death when a restrained person suddenly dies is a problem for death investigators. Twenty-one cases of death during prone restraint are reported as examples of the common elements and range of variation in these apparently asphyxial events. A reasonable diagnosis of restraint asphyxia can usually be made after ruling out other causes and collecting supportive participant and witness statements in a timely fashion. Common elements in this syndrome include prone restraint with pressure on the upper torso; handcuffing, leg restraint, or hogtying; acute psychosis and agitation, often stimulant drug induced; physical exertion and struggle; and obesity. Establishing a temporal association between the restraint and the sudden loss of consciousness/death is critical to making a correct determination of cause of death.     

Pulmonary arterial fibromuscular dysplasia: a rare cause of fulminant lung hemorrhage

Arterial fibromuscular dysplasia (FMD) represents a collection of noninflammatory and nonatherosclerotic vascular diseases with a poorly understood etiology. Classically occurring in renal and cerebral arteries, this entity has also been reported in coronary, carotid, and other medium and small arteries. One case occurring in the pulmonary vasculature has been reported. Fatal hemothorax and lung hemorrhage have multiple causes, including other vascular malformations and connective tissue disorders; however, cases of pulmonary FMD are exceedingly rare. We report what appears to be the second such association, occurring in a 69-year-old man. The patient presented with a 3-week history of increasing dyspnea, fatigue, and productive cough; 3 days of increasing back and chest pain; and syncope. Chest radiograph showed a "white-out" of the left lung. The patient died shortly after admission from a fulminant respiratory disease of undetermined etiology. At autopsy he was found to have a massive left hemothorax resulting from an unsuspected pulmonary arterial fibromuscular dysplasia.     

A deadly anti-SIDS device

The diagnosis of sudden infant death syndrome (SIDS) has been an enigma to medical examiners and coroners for decades. The recent drastic decrease in the number of SIDS cases has been associated with infants sleeping supine instead of prone. The apparent relation between sleeping position and SIDS has led to the marketing of several positioning sleep aids. We report a case of the improper use of one such device which resulted in the death of an infant.     

Distributive and Procedural Justice in Seven Nations

The paper examines the impact of distributive justice and procedural justice variables on judgments in seven countries (Bulgaria, France, Hungary, Poland, Russia, Spain, and the United States). Subjects were presented with each of two experimental vignettes: one in which the actor unsuccessfully appeals being fired from his job and one in which the actor unsuccessfully goes to an employment agency to seek a job; they were asked to rate the justness of the outcome and how fairly the actor had been treated. The vignettes manipulated deservingness and need of the actor (distributive justice factors) and impartiality and voice in the hearing (procedural justice factors). Four hypotheses were tested: first, a distributive justice hypothesis that deservingness would be more important than need in these settings; second, a procedural justice hypothesis that the importance of voice and impartiality vary depending on the nature of the encounter and the forum in which it is resolved; third, because of their recent socialist experience, Central and Eastern European respondents make greater use of need information and less use of deservingness information than Western respondents; and fourth, that distributive justice and procedural justice factors interact. The distributive justice hypothesis is supported in both vignettes. The procedural justice hypothesis receives some support. Impartiality is more important in the first vignette and voice is more important in the second vignette. The interaction hypothesis was not supported in the first vignette, but does receive some support in the second vignette. The cultural hypothesis is not supported in either vignette. The implications for distributive and procedural justice research are discussed.     

Persian leopard (Panthera pardus) attack in Oklahoma: case report

The authors report a fatal case of a Persian leopard (Panthera pardus) attack in an animal sanctuary in Oklahoma. The victim was a 53-year-old Costa Rican woman who was attempting to feed the animal when she was attacked and killed. Autopsy, radiography, fingerprint analysis, microbiologic cultures, and dental impressions were used to evaluate the case. These simple techniques can be applied to similar cases involving wild and domestic animal attacks.     

Morphine-3-D glucuronide stability in postmortem specimens exposed to bacterial enzymatic hydrolysis

Medical examiners frequently rely on the finding of free morphine present in postmortem specimens to assist in certifying deaths associated with narcotics. In vitro hydrolysis of morphine-3-D glucuronide (M3DG) to free morphine was studied using variable specimen pH, initial degree of specimen putrefaction, storage temperature and time, and the effectiveness of sodium fluoride (NaF) preservation. Reagent M3DG was added to opiate-free fresh blood and urine and to autopsy-derived blood specimens. Reagent bovine glucuronidase was also added to certain specimens. Freshly collected and refrigerated NaF-preserved blood produced minimal free morphine, whereas four of five autopsy blood specimens produced free morphine from M3DG. Increased storage time, temperature, and initial degree of putrefaction resulted in greater free morphine generation despite the absence of viable bacteria. Hydrolysis occurring during specimen storage can generate free morphine from M3DG and may result in erroneous conclusions in certifying narcotic deaths.     

Stereolithography: a potential new tool in forensic medicine

Stereolithography is a computer-mediated method that can be used to quickly create anatomically correct three-dimensional epoxy and acrylic resin models from various types of medical data. Multiple imaging modalities can be exploited, including computed tomography and magnetic resonance imaging. The technology was first developed and used in 1986 to overcome limitations in previous computer-aided manufacturing/milling techniques. Stereolithography is presently used to accurately reproduce both the external and internal anatomy of body structures. Current medical uses of stereolithography include preoperative planning of orthopedic and maxillofacial surgeries, the fabrication of custom prosthetic devices; and the assessment of the degree of bony and soft-tissue injury caused by trauma. We propose that there is a useful, as yet untapped, potential for this technology in forensic medicine.
