Evolution of the Psychological Autopsy: Fifty Years of Experience at the Los Angeles County Chief Medical Examiner‐Coroner's Office

The origin of the psychological autopsy was in the late 1950s and the result of a collaboration between the Los Angeles County Chief Medical Examiner‐Coroner's Office and the Los Angeles Suicide Prevention Center. It was conceptualized as a thorough retrospective analysis of the decedent's state of mind and intention at the time of death. It was used initially in “equivocal” deaths where the manner of death was possibly either suicide or accident. Later, it was used in cases where a party (primarily family members) protested the Medical Examiner‐Coroner's suicide determination. Over the past 25 years, the University of Southern California Institute of Psychiatry, Law, and Behavioral Science has served as the psychiatric/psychological consultants to the Coroner's Department. Research findings, the use of this approach in high‐profile cases, and the most recent manner in which the psychological autopsy is conducted are discussed.     

Acute arsenic poisoning: clinical, toxicological, histopathological, and forensic features

This report describes a suicide case by acute arsenic intoxication via intravenous injection. A 30-year-old woman injected arsenic As (V) (sodium arseniate disodique: Disodium Hydrogena Arsenik RP) in a successful suicide attempt. Three hours following administration, the woman developed severe digestive symptoms. She was admitted to a hospital and transferred to the intensive care unit within 12 h of the massive administration of arsenic. Despite therapeutic efforts, over the next 2 h she developed multiorgan failure and died. A postmortem examination was performed. Pulmonary edema and congestion of liver were apparent. As (V) and As (III) were determined by high performance liquid chromatography and inductively coupled plasma mass spectrometry after mineralization of samples by concentrated nitric acid. Toxicological analysis revealed high concentrations of arsenic in biological fluids as well as in organs. Histopathological examination showed a typical indication of myocarditis. These findings were in agreement with acute arsenic poisoning. The symptoms developed by this young woman (intoxication by intravenous administration) were comparable to oral intoxication. The clinical signs, survival time, and administration type are discussed in light of the literature on acute and chronic arsenic poisoning.     

Axonal injury in young pediatric head trauma: a comparison study of β-amyloid precursor protein (β-APP) immunohistochemical staining in traumatic and nontraumatic deaths

We tested the independent utility of β-amyloid precursor protein (β-APP) immunohistochemical staining as evidence of brain trauma in the deaths of young children. Blinded reviewers retrospectively reviewed immunostained brain tissues from homicidal deaths, age-matched control cases without evidence of trauma, as well as cases of sudden infant death syndrome (SIDS). The reviewers correctly identified five of the seven cases with documented inflicted head trauma. However, one of seven age-matched control cases and one of 10 SIDS/sudden unexplained death in infancy (SUDI) cases demonstrated staining patterns similar to those seen in cases of inflicted trauma. We discuss these cases and the circumstances surrounding them with the intent to explain the difficulties associated with immunohistological interpretation of axonal injury. Although the utility of β-APP is quite powerful if not confounded by global hypoxic-ischemic injury, ultimately, β-APP studies should be only one piece of information in the determination of cause and manner of death.     

Ethical and legal consideration of prisoner's hunger strike in Serbia

Hunger strike of prisoners and detainees remains a major human rights and ethical issue for medical professionals. We are reporting on a case of a 48-year-old male sentenced prisoner, intravenous heroin user, who went on a hunger strike and died 15 days later. Throughout the fasting period, the prisoner, who was capable of decision making, refused any medical examination. Autopsy findings were not supporting prolonged starvation, while toxicology revealed benzodiazepines and opiates in blood and urine. Cause of death was given as "heroin intoxication" in keeping with detection of 6-MAM. Legal and ethical issues pertinent to medical examination and treatment of prisoners on hunger strike are explored in accordance with legislation and professional ethical standards in Serbia. A recommendation for the best autopsy practice in deaths following hunger strike has been made.

2009 H1N1 Fatalities: The New Mexico Experience

Abstract: Histopathologic features of New Mexico 2009 H1N1 fatalities have not been representative of those reported nationwide. We retrospectively reviewed medical records of all New Mexico 2009 pandemic influenza A (pH1N1) fatalities (n = 50). In cases in which autopsy was performed (n = 12), histologic sections and culture results were examined. In contrast to previously published studies, the majority of our fatalities did not have diffuse alveolar damage (DAD) (2/12; 16.7%). Common findings included pulmonary interstitial inflammation and edema, tracheobronchitis, and pneumonia. Two cases had significant extra‐pulmonary manifestations: myocarditis and cerebral edema with herniation. The majority had a rapid disease course: range from 1 to 12 days (median, 2 days), and Native Americans were disproportionately represented among fatalities. These findings suggest that New Mexico H1N1 fatalities generally did not survive long enough to develop the classic picture of DAD. Pathologists should be aware that H1N1 may cause extra‐pulmonary pathology and perform postmortem cultures and histologic sampling accordingly.     

A Minimally Invasive Technique for the Detection and Analysis of Pulmonary Fat Embolism: A Feasibility Study*

We investigated the feasibility of postmortem percutaneous needle biopsy (PNB) for obtaining pulmonary samples adequate for the study of pulmonary fat embolism (PFE). Samples of both lungs were obtained from 26 cadavers via two different methods: (i) PNB and (ii) the double-edged knife technique, the gold standard at our institute. After water storage and Sudan III staining, six forensic pathologists independently examined all samples for the presence and severity of PFE. The results were compared and analyzed in each case regarding the vitality of the PFE and its relationship to the cause of death. The results showed that PFE was almost identically diagnosed and graded on the samples obtained via both methods. The discrepancies between the two techniques did not affect the diagnoses of vitality or cause of death related to PFE. This study demonstrates the feasibility of the PNB sampling method for the diagnosis and interpretation of PFE in the postmortem setting.     

The forensic deaths caused by pesticide poisoning between the years 2006 and 2009 in Izmir, Turkey

Pesticide poisoning is still a significant health problem in Turkey. We conducted a retrospective study of autopsy cases at Izmir Branch of the Council of Forensic Medicine to describe the characteristics of deaths caused by pesticide poisoning between 2006 and 2009. The distributions of the cases according to gender and age were as follows: men 74.1% (n = 40, mean [±SD] age, 44.7 ± 14.1), women 25.9% (n = 14, mean [±SD] age, 39.2 ± 18.9). The majority of pesticide-poisoning deaths were suicides (n = 43, 80%) followed by accidents (n = 4, 8%) and homicide (n = 1, 2%). The manner of death could not be determined in six cases (11%). Suicides mostly occurred at home (n = 26, 63%) (p < 0.05). Methomyl was the most frequent pesticide (n = 9, 17%) among the all cases. This study reported that most of the pesticides found in poisoning cases were highly hazardous types. Combined efforts of medical professionals and law makers are needed for enacting strict laws against highly hazardous pesticides.     

Sudden Cardiac Death in a Young Man with Migraine-associated Arrhythmia

A 31-year-old man with migraine-induced syncope and bradycardia with subsequent pacemaker implantation died unexpectedly. Clinically unsuspected cardiac anomalies were found at autopsy including myocardial bridging of the left anterior descending artery and shelf-like coronary artery ostia. Nortriptyline was identified by toxicologic analysis. A review of the autopsy findings, the historical information, and the effects of the possible arrhythmogenic circumstances is undertaken and the potential contributions to the death are discussed. Cardiac arrhythmias have been documented during migraines. Coronary artery bridging has been known to lead to ischemia and infarction, ventricular tachycardia, and sudden death; however, these are very rare sequelae. Congenital coronary artery anomalies have been linked to sudden cardiac death, but only rarely cause death in people younger than 31 years. Migraines and the autopsy findings described have been associated with cardiac arrhythmia and sudden death. Altogether, they led to the unexpected death of this young man.
