Nursing home deaths which fall under the jurisdiction of the coroner: an 11-year retrospective study.

Twenty percent of deaths in the United States occur in nursing homes, yet less than 1% come to autopsy. The current study analyzed causes and manners of death in all nursing homes between 1993 and 2003, investigated by the coroner of Allegheny County, PA, which has the second highest elderly population in the United States. Two hundred eight decedents were identified, aged 19 to 91 years, 58% women and 42% men, 88% Caucasian and 22% African-American. Fifty-eight percent were accidental and 38.5% were natural manners of death, with 2 homicides, 2 suicides, and 3 undetermined cases. The manner of death was significantly different between Caucasians and African-Americans, with 92.6% of accidental deaths occurring in Caucasians and 6.6% in African-Americans (P < 0.1). Most common natural deaths were arteriosclerotic cardiovascular disease, nonarteriosclerotic cardiovascular disease, pneumonia, pulmonary thromboembolism, chronic obstructive pulmonary disease (COPD), seizure disorder, and atraumatic intracranial hemorrhage. Blunt force trauma was the single most commonly identified traumatic accidental death. Accidental deaths were more common in Caucasians than African-Americans. Homicides and suicides were rare events (<2%). Blunt force trauma is a major autopsy finding in accidental nursing home deaths, and a root-cause analysis may be helpful in developing policies and procedures to decrease the incidence of blunt force trauma.

Accurately assessing elderly fall deaths using hospital discharge and vital statistics data.

Historically, fatal injury monitoring and surveillance have relied on mortality data derived from death certificates (DC). However, problems associated with utilizing DC have been well documented. Recently, access to and utilization of hospital discharge data (HDD) have offered a new and important secondary source of data regarding in-hospital deaths. However, studies have shown that discrepancies between the HDD and the corresponding DC often exist. This discrepancy was especially evident when comparing HDD to the vital statistics data (VSD) for deaths by falls among those aged 65 and over in 19 states. This was a retrospective forensic review of elderly (age 65 and over) fall-associated fatalities (E880-E888) identified from HDD and VSD in Allegheny County, Pennsylvania, between 1997 and 1998. Seventy-seven cases were identified, with the original manner of death listed as natural (34), suicide (1), and accidental (42) on the DC. Following a forensic review of the cases, the manner of the death on the DC should have been changed from natural to accidental in 28% (n = 12) of the cases, representing an undercount in the VSD. Undercounts were due to a failure of clinicians to account for the significance of a fall event that contributed to subsequent pathology and death. In addition, in that 22% (n = 17) of the HDD fall-associated deaths, the fall did not contribute directly or sequentially to the underlying cause of death, thereby representing an overcount in the HDD. Based on these findings we recommend (1) elderly fall surveillance systems should only count HDD E-coded falls that demonstrate a serious traumatic injury which directly or subsequently results in death, (2) all in-hospital fall-associated deaths should be reported to and reviewed by coroner/Medical Examiner offices for determination of the cause and manner of death, and (3) physicians should be better educated in properly completing death certificates.

The risk of body packing: a case of a fatal cocaine overdose.

The process of swallowing or inserting illegal packets of drugs for the purpose of evading law enforcement officers carries risks other than criminal charges. It can be fatal. Individuals engaged in such activities are called "Body Packers" or "Mules". The most frequent cause of the death among body packers is acute drug intoxication due to rupture of the package(s) within the gastrointestinal tract. We present the first documented case of a body packer that died from cocaine intoxication following the rupture of packets of cocaine in Western Pennsylvania.

Suicides following bariatric surgery for the treatment of obesity.

The proportion of the United States population living with bariatric surgery has increased exponentially since the mid 1990s. It is pertinent to study and understand the mortality patterns of this emergent population cohort and determine the role bariatric surgery may play in these mortality patterns. We present the forensic and clinical characteristics of three cases of suicide following bariatric surgery for the treatment of morbid obesity. The clinical history in each case included recurrent major depressive disorder before and after surgery. Surgery-suicide intervals were 12 months, 27 months and 26 months, respectively. Pre-surgery and pre-mortem body mass indices were 37.7 and 22.2 kg/m(2); 42.0 and 25.0 kg/m(2); 39.5 and 29.4 kg/m(2). Depressive disorder may persist in the bariatric surgery patient despite successful surgical control of obesity.

Postmortem grading of cerebral contusions : A proposed modification of the adams' contusion index with re-definition of anatomic markers.

In the 1970s, J. H. Adams and other researchers at the Institute of Neurological Sciences, Glasgow, Scotland introduced a grading system for the quantification and analysis of contusions of the brain. They derived a brain contusion index based on regional surface distribution and parenchymal depth of contusions of the brain. Following a subsequent modification of this scheme in the 1980s, they recommended evolving modifications that will fit a variety of possible applications. Having tested the applicability of this grading system for the forensic/medico-legal autopsy, we have encountered some applied anatomic limitations and have derived a modification that addresses these limitations in reference to the forensic/medico-legal autopsy.We recommend a two-tier system based on the Adams' system, which quantifies contusions of the brain by the gyral spread of contusions and by the parenchymal depth of penetration of contusions with a re-definition of the lobar distinctions and classifications of the brain. Gyral spread is assigned a grading scheme of 0-3 and the parenchymal depth of contusions is assigned a grading scheme of 0-4. A lobar contusion score is derived by multiplying the two assigned grades. A total brain contusion index is derived by summating all the lobar contusion scores. This reproducible grading system can be applied to routine bench forensic neuropathology reporting, court room illustrations and in comparative research analysis of brain trauma subjects.

Forensic pathology and forensic epidemiology of suicides in allegheny county, pennsylvania : A 10-year retrospective review (1990-1999).

Suicide has assumed epidemic proportions and constitutes a major public health issue throughout the United States. Suicide remains one of the top eight leading causes of death, accounting for approximately 30,000 deaths annually. The understanding and prevention of suicide requires a multidisciplinary approach that involves psychosocial and medical specialties starting with a forensic analysis of the characteristics of suicide. The aim of this 10-year (1990-1999) retrospective study was threefold: first, to examine the forensic epidemiological characteristics of suicides examined by the Allegheny County Coroner's Office; second, to describe emerging epidemiological patterns of suicide; and finally, to make recommendations for preventive measures. A total of 1447 suicides were identified, with 1164 males (80%) and 283 females (20%) resulting in a male to female ratio of 4:1. The race distribution comprised 90% whites, 9% blacks, and 1% other races. The age of suicide victims ranged from 13 to 96 years old with a peak within the 31- to 40-year-old age group, which represented 24.5% of all suicides. Overall, 40% of the victims were single and more blacks than whites were single. The greatest number of suicides occurred in July, with the least in December. Suicides most frequently occurred between 9:01 AM and 3:00 PM. Suicide notes were present in 29% of all suicides. Firearm injuries, hanging, and drug overdose were the leading methods of suicide. Use of firearms was the leading method of suicide among both sexes. Female drug overdose deaths outnumbered male drug overdose deaths. The 10 most common overdose drugs were all central nervous system depressants, with amitriptyline being the most common prescription overdose drug. Based on reported antecedent trends in suicides, we make two recommendations regarding suicide prevention: (1) physicians should be educated to replace the prescription of older and more toxic antidepressants such as amitriptyline with newer and less toxic antidepressants such as serotonin reuptake inhibitors; and (2) firearms should be made inaccessible to individuals with risk factors for suicide, especially in the home.

Cardiac concussion: definition, differential diagnosis, and cases presentation and the legal ramification of a misdiagnosis.

A cardiac concussion is caused by a sudden, nonpenetrating, localized impact to the chest that is theorized to result in almost simultaneous sudden death from a disruption to the conductive system. The detailed external/internal forensic examination of the body reveals no evidence of structural, pathologic, or histologic signs of trauma to the heart. A cardiac concussion is a rare and often overlooked cause of sudden death. This type of sudden death is typically seen among younger individuals participating in sports involving projectiles and, to a lesser degree, where collisions occur. Cardiac concussions are clinically, pathologically, and chemically different from a cardiac contusion. The objective of this paper will be to define cardiac concussion, differentiate between cardiac concussion and cardiac contusion, and describe the clinical and pathologic features of a 32-year-old white male who died of a cardiac concussion following a collision with a catcher during a softball game. The civil ramification of incorrectly diagnosing the manner of death in cases of death involving a cardiac concussion will also be addressed.

Postbariatric surgery deaths, which fall under the jurisdiction of the coroner.

Obesity has attained epidemic proportions in the United States, with more than 50% of adults classified as overweight or obese. If untreated, morbidly obese patients have a 1 in 7 chance of reaching normal life expectancy. The surgical treatment of obesity has emerged as the most effective treatment modality in long-term weight control and has become increasingly popular, with attendant postoperative complications and death. We performed a cross-sectional, coroner based, 2-year retrospective review of archival case records for decedents who died following bariatric surgery for the treatment of obesity to identify underlying causes of death and forensic characteristics of this cohort. Fifteen (0.5%) out of 3097 archival cases died following bariatric surgery, with approximately 73% of decedents dying within 6 months of surgery. The underlying causes of death in 80% of decedents were natural comorbidities of obesity, with cardiovascular diseases (33%) being the most frequent causes of death, followed by gastrointestinal diseases (20%), acute pulmonary thromboembolism (13%), and acute bacterial pneumonia (13%). The majority of decedents were white females who remained morbidly obese after bariatric surgery. Only 2 decedents died of direct inadvertent/accidental surgical complications.

Death by chainsaw: fatal kickback injuries to the neck.

Each year over 3 million new chainsaws are sold in the United States. The operation of these newer saws combined with the millions of older chainsaws in circulation results in over 28,000 chainsaw-related injures annually. The majority of the injuries involve the hands and lower extremities with less than 10% involving injuries to the head and neck regions. Deaths while operating a chainsaw are extremely rare. The most common hazards associated with chainsaws are injuries caused by kickback, pushback, and pull-in. Kickback is the most common and poses the greatest hazard. Kickback occurs when the rotating chain is stopped suddenly by contact with a more solid area throwing the saw rapidly backward toward the operator. The cause of most injuries can be traced to improper use of the saw or poor judgment on part of the operator. We present two fatal chainsaw deaths; one with an older style saw, and the other with a modern type. In both cases the victims died from fatal injuries received to the neck region from a chainsaw kickback. The first case involved a 49-year-old white male operating an older style chainsaw with limited safety features. The second case involved a 38-year old white male who was operating a newer model chainsaw equipped with a low kickback chain in an unsafe manner.

Deaths among criminal suspects, law enforcement officers, civilians, and prison inmates: a coroner-based study.

During the interaction between a criminal suspect and a law enforcement officer, the risk of death to the suspect, police, or civilians is increased. Unfortunately, very little information is available on the death risks arising from this interaction. This study provides an assessment of the risk of death to law enforcement officers, suspects, and bystanders by separating the interactions into the following 4 phases: (1) events prior to and during arrest; (2) police pursuits or chases; (3) transport of the suspects; and (4) during incarceration. A 5-year (1994-1998) retrospective coroner-based study of all deaths that occurred during these 4 phases was conducted in Allegheny County, Pennsylvania. A total of 77 cases were identified; 14 deaths (18.1%) occurred prior to or during arrest, 10 (12.9%) during police chases, 2 (2.6%) occurred while the actors were being transported, and 51 (66.2%) during incarceration. The majority of cases (98.7%) were males, blacks (63.6%), and single (50.6%). The respective risks of death by phase were prearrest/arrest, 6.5 per 100,000 arrests; transport, 0.93 deaths per 100,000 arrests; and incarceration, 268 deaths per 100,000 inmates. Study showed the following: (1) risk of death to offenders was greatest during police pursuits; (2) the risks during arrests are not insignificant and involved an officer being threatened with a weapon in one-third of the events; and (3) deaths among inmates were primarily due to natural causes.

Death during transforaminal epidural steroid nerve root block (C7) due to perforation of the left vertebral artery.

Treatment for individuals suffering from migraines and pain due to an inflammation or impingement of a nerve range from noninvasive methods such as massage, physical therapy, and medications to invasive methods such as epidural steroid injections and surgery. Each method of treatment has an associated level of risk. While minor to moderate complications from such procedures do occur, deaths are very rare. We report the first cited case of a death associated with the pain management procedure called nerve root block, also referred to as a transforaminal epidural steroid injection. We present the medical history and autopsy findings of a 44-year-old white female who died of massive cerebral edema secondary to the dissection of the left vertebral artery and subsequent thrombosis due to the perforation of that artery by a 25-gauge spinal needle during a C-7 nerve root block.

Kawasaki disease: a review of pathologic features of stage IV disease and two cases of sudden death among asymptotic young adults.

Kawasaki disease (KD) primarily affects infants and is rarely fatal in young adults. The sequelae of KD can result in death months to years after the exposure to the causative agent. Such deaths are defined as Stage IV KD, which is characterized by the formation of multiple aneurysms in the coronary arteries, calcification and recanalization of the obstructed portions of the coronary arteries, and myocardial infarction and ischemia. A 10-year retrospective review of sudden deaths in Allegheny County, Pennsylvania, identified two fatal cases of Stage IV KD involving young adults. These two young adults were healthy and completely asymptomatic; they had no identifiable risk factors for cardiovascular disease before the fatal event. One adult was involved in vigorous exercise, and the other was recumbent in bed at the time of death.
