RESUMO
Postmortem computed tomography (PMCT) has been integrated into the practice of many forensic pathologists. To evaluate the utility of PMCT in supplementing and/or supplanting medicolegal autopsy, we conducted a prospective double-blind comparison of abnormal findings reported by the autopsy pathologist with those reported by a radiologist reviewing the PMCT. We reviewed 890 cases: 167 with blunt force injury (BFI), 63 with pediatric trauma (under 5 years), 203 firearm injuries, and 457 drug poisoning deaths. Autopsy and radiology reports were coded using the Abbreviated Injury Scale and abnormal findings and cause of death (COD) were compared for congruence in consensus conferences with novel pathologists and radiologists. Overall sensitivity for recognizing abnormal findings was 71% for PMCT and 74.6% for autopsy. Sensitivities for PMCT/autopsy were 74%/73.1% for BFI, 61.5%/71.4% for pediatric trauma, 84.9%/83.7% for firearm injuries, and 56.5%/66.4% for drug poisoning deaths. COD assigned by reviewing PMCT/autopsy was correct in 88%/95.8% of BFI cases, 99%/99.5% of firearm fatalities, 82.5%/98.5% of pediatric trauma deaths, and 84%/100% of drug poisoning deaths of individuals younger than 50. Both autopsy and PMCT were imperfect in recognizing injuries. However, both methods identified the most important findings and are sufficient to establish COD in cases of BFI, pediatric trauma, firearm injuries and drug poisoning in individuals younger than 50. Ideally, all forensic pathologists would have access to a CT scanner and a consulting radiologist. This would allow a flexible approach that meets the diagnostic needs of each case and best serves decedents' families and other stakeholders.

We explored the value of postmortem computed tomography (PMCT) to augment autopsy in evaluating strangulation fatalities. A literature search identified 16 studies describing autopsy findings in 576 deaths and two studies describing autopsy and PMCT findings in six deaths. Similar cases were identified from our institution, yielding 130 deaths with autopsy findings and 14 deaths with both autopsy and PMCT findings. The presence of laryngohyoid fracture and soft tissue hemorrhage was compared from autopsy and autopsy+PMCT cases. The detection rates of fractures in autopsy and autopsy+PMCT cases were not significantly different. PMCT identified all fractures observed at autopsy and five fractures not identified. While PMCT may not detect soft tissue injuries in decomposed remains or subtle internal hemorrhages in neck injury, it is equally able to detect bony injuries as autopsy and might surpass autopsy in detecting subtle fractures. We conclude PMCT is useful to supplement autopsy in strangulation cases.

Background: Postdiarrheal hemolytic-uremic syndrome (D+HUS) following Shiga toxin-producing Escherichia coli (STEC) infection is a serious condition lacking specific treatment. Host immune dysregulation and genetic susceptibility to complement hyperactivation are implicated in non-STEC-related HUS. However, genetic susceptibility to D+HUS remains largely uncharacterized. Methods: Patients with culture-confirmed STEC diarrhea, identified through the Centers for Disease Control and Prevention FoodNet surveillance system (2007-2012), were serotyped and classified by laboratory and/or clinical criteria as having suspected, probable, or confirmed D+HUS or as controls and underwent genotyping at 200 loci linked to nondiarrheal HUS or similar pathologies. Genetic associations with D+HUS were explored by multivariable regression, with adjustment for known risk factors. Results: Of 641 enrollees with STEC O157:H7, 80 had suspected D+HUS (41 with probable and 32 with confirmed D+HUS). Twelve genes related to cytokine signaling, complement pathways, platelet function, pathogen recognition, iron transport, and endothelial function were associated with D+HUS in multivariable-adjusted analyses (P ≤ .05). Of 12 significant single-nucleotide polymorphisms (SNPs), 5 were associated with all levels of D+HUS (intergenic SNP rs10874639, TFRC rs3804141, EDN1 rs5370, GP1BA rs121908064, and B2M rs16966334), and 7 SNPs (6 non-complement related) were associated with confirmed D+HUS (all P < .05). Conclusions: Polymorphisms in many non-complement-related genes may contribute to D+HUS susceptibility. These results require replication, but they suggest novel therapeutic targets in patients with D+HUS.

While it is recognized that veterans have increased rates of depression, post-traumatic stress disorder (PTSD), suicide, and substance use disorders, rates of homicide and unintentional injury deaths in veterans have been minimally investigated. We evaluated all non-natural deaths in New Mexico veterans between 2002 and 2011 in comparison with non-natural deaths among non-veterans. We reviewed all decedents in New Mexico with a history of military service and investigated by the medical examiner, excluding natural deaths and deaths due to fall from standing height. The most common manner of death was unintentional injury (62%), most of these deaths due to motor vehicle accidents (29%) followed by unintentional overdose (26%). Suicide rates among veterans were consistently higher than the general population. The most common mechanism of suicide in men was gunshot wound (72%), and intentional overdose in women (49%). Services are needed for veterans that are tailored to all ages and both sexes.

To better understand the changing toxicology trends in suicidal drug overdoses in the setting of an increased national trend of multidrug overdoses, a retrospective review of electronic records from New Mexico's Office of the Medical Investigator database was performed between 2008 and 2012 to assess the drug type and current risk factors in suicide deaths. Information on demographics, circumstances, suicide risk factors, toxicology findings, and death certificates was collected and analyzed. Three hundred and forty-two suicide cases of suicide overdoses were identified. Decedents were predominantly female (61.8%). Scene investigation revealed risk factors including suicide ideation (47.4%), previous suicide attempts (38%), and suicide note (38%). Psychiatric illness was present in 72% of cases, with depression being the most common illness. Chronic pain was seen in 27.2% of cases. Most deaths were attributed to multiple drugs (76%). Utilizing the toxicology information will assist in creating public awareness and provide a framework to support targeted efforts to attempt to prevent future suicides.

Leukocyte chemotactic factor 2 (LECT2) amyloidosis is one of the most recently described types of amyloidosis. Since its description, it has been found to be one the most common types of amyloidosis in large series of amyloid cases involving the kidney and liver in the United States, where it primarily affects patients of Hispanic ethnicity. We sought to investigate the prevalence of this disease among Hispanic adult decedents who had an autopsy performed at the New Mexico Office of the Medical Investigator and determine the organ distribution of amyloid deposition. LECT2 amyloid deposits were identified within the kidney in 3.1% of Hispanic decedents. It was consistently deposited in the liver, spleen, adrenals, and lungs but did not involve the myocardium or brain. LECT2 amyloidosis is likely not rare among Hispanics in the Southwest United States and could represent an important but under-recognized etiology of chronic kidney disease in this population.

To better understand lightning deaths, a retrospective review of electronic records from New Mexico's Office of the Medical Investigator database was performed between 1977 and 2009 to update and assess current risk factors. Information on demographics, circumstances, autopsy, and death certificates were collected and analyzed. Fifty-four decedents were identified, ages 2-71 years old (mean 34 years old), 42 males and 12 females. Common racial/ethnic groups were non-Hispanic Whites and American Indians (together comprising 72% of all cases). Physical findings were often related to the heat carried by the electrical current including clothing alterations (29.6%) and burning of skin (53.7%). Most deaths occurred on weekend afternoons in summer months, associated with recreational activities or agricultural work, and rural locations (77.8%). Utilizing the demographic information, clustered events, and associated outdoor activities will assist in creating public awareness and provide a framework to support targeted warnings in an attempt to prevent future deaths.

Fentanyl is a synthetic opioid agonist used for pain control. Often administered as a transdermal patch, it is an interesting drug for study of postmortem redistribution. We hypothesized that fentanyl concentrations would increase over time after death, as measured in blood drawn on the day prior to autopsy and in blood drawn at the time of autopsy in ten cases where fentanyl patches were identified at the scene. Concentrations were compared, and heart blood to femoral blood ratios were calculated as markers of postmortem redistribution. Fentanyl concentrations measured in peripheral blood drawn the day of autopsy (peripheral blood 2 [PB2]) were higher than those drawn the day prior to autopsy (peripheral blood 1 [PB1]) with a mean ratio (PB2/PB1) of 1.80. The ratio of heart blood concentrations (HB) to femoral blood concentrations drawn at autopsy (PB2) had a mean ratio (HB/PB2) of 1.08. Some cases had blood from the same source analyzed at two different laboratories, and concentrations of fentanyl in those samples showed inter- and intralaboratory differences up to 25 ng/mL. Postmortem fentanyl concentrations may be affected by antemortem factors, postmortem redistribution, and laboratory variability. Forensic pathologists must use caution in interpreting fentanyl levels as part of death investigation.

To better understand risk factors and populations at risk of childhood fatalities, a review of all records of childhood deaths (≤19 years) between 2000 and 2010 from New Mexico's statewide medical examiner was conducted. Annually, 313-383 childhood deaths were investigated (3820 total). Males and American Indians were overrepresented (62% and 20.4% of deaths, respectively). The most common manner of death was natural (44.8%), followed by accidental (31.4%), homicide (8.8%), suicide (8.8%), and undetermined (4.1%). Infants under 1 year of age accounted for 41.4% of deaths. Motor vehicle crashes were responsible for the majority of accidental deaths (69%), followed by unintentional overdoses (6.9%), and drowning (5.3%). Gunshot wounds, either intentional or unintentional, caused 10.7% of childhood deaths. Complete medico-legal investigation of childhood fatalities is needed to provide public health agencies with adequate data to evaluate and prevent childhood deaths.

Medical examiner/coroner's (ME/C) offices investigate sudden, violent, and unexpected deaths, leaving those close to the deceased suffering traumatic loss with little in terms of support and counseling. We investigated a grief services program (GSP) at the New Mexico Office of the Medical Investigator (OMI) to better understand the needs of bereaved individuals, identify the services provided, and propose our findings as a model for others. A total of 1085 contacts occurred over 1 year, with the majority occurring at OMI (60.5%), followed by telephone (23.1%). Support was primarily provided to those suffering a loss due to homicide (28.8%) and suicide (26.1%). The roles grief counselors play in the setting of a GSP and ME/C office are multiple. Given the frequent utilization of OMI's GSP and diverse reasons for visits, it is apparent there is a need for GSPs at ME/C offices, particularly given the traumatic nature of deaths investigated by ME/Cs.

RESUMO
BACKGROUND: Salmonella enterica causes an estimated 1 million cases of domestically acquired foodborne illness in humans annually in the United States; Enteritidis (SE) is the most common serotype. Public health authorities, regulatory agencies, food producers, and food processors need accurate information about rates and changes in SE infection to implement and evaluate evidence-based control policies and practices. METHODS: We analyzed the incidence of human SE infection during 1996-2009 in the Foodborne Diseases Active Surveillance Network (FoodNet), an active, population-based surveillance system for laboratory-confirmed infections. We compared FoodNet incidence with passively collected data from complementary surveillance systems and with rates of SE isolation from processed chickens and egg products; shell eggs are not routinely tested. We also compared molecular subtyping patterns of SE isolated from humans and chickens. RESULTS: Since the period 1996-1999, the incidence of human SE infection in FoodNet has increased by 44%. This change is mirrored in passive national surveillance data. The greatest relative increases were in young children, older adults, and FoodNet sites in the southern United States. The proportion of patients with SE infection who reported recent international travel has decreased in recent years, whereas the proportion of chickens from which SE was isolated has increased. Similar molecular subtypes of SE are commonly isolated from humans and chickens. CONCLUSIONS: Most SE infections in the United States are acquired from domestic sources, and the problem is growing. Chicken and eggs are likely major sources of SE. Continued close attention to surveillance data is needed to monitor the impact of recent regulatory control measures.

BACKGROUND: The objective of this study was to characterize unintentional drug overdose death patterns among Hispanic ethnicity/sex strata by residence in New Mexico counties that border Mexico and non-border counties. METHODS: We analyzed medical examiner data for all unintentional drug overdose death in New Mexico during 2005-2009. Logistic and Poisson regression was used to examine the relationship of unintentional drug overdose death with border residence and demographics. Risk of overdose death was examined by the interactions of ethnicity, sex and border residence. RESULTS: During 2005-2009, the statewide drug overdose death rate was 17.6 per 100,000 (n=1812). Border decedents were more likely to have died from overdose of prescription opioids other than methadone (Schedule II, Adjusted Odds Ratio (aOR)=1.98; Schedule III/IV, aOR=1.56) but less likely to have died from heroin overdose (aOR=0.35), compared to non-border decedents. In population-based analyses, people living in border counties had lowest rates of overall overdose death and from illicit drugs, particularly heroin and cocaine. Hispanic males (adjusted incidence rate ratio [aRR]=2.41), Hispanic females (aRR=1.77) and non-Hispanic males (aRR=1.37) from non-border counties had higher risk of drug overdose death than their counterparts from border counties. Border residence had no effect on risk of drug overdose death among non-Hispanic females. CONCLUSIONS: Residents in border counties incurred a protective effect for drug overdose death, most pronounced among Hispanics. There is a component of overdose death risk for which border residence is a proxy, likely an array of cultural and healthcare-related factors.

Since its approval in the United States, fentanyl has become increasingly popular for the medical management of pain and as a substance of abuse. Fentanyl is unique among the opioids in its widespread use with a transdermal delivery system, which contributes to its unique pharmacokinetics and abuse potential. We examined the demographics of deaths with fentanyl identified on toxicologic analysis and reviewed specific challenges in the laboratory detection of postmortem fentanyl levels. The New Mexico Office of the Medical Investigator database was searched for all cases from January 1986 through December 2007 with fentanyl reported as present or quantified. Those deaths with a cause of death identified as drug overdose were then analyzed separately. From 1986 to 2007, 154 cases were identified with fentanyl present in postmortem samples, with 96 of the cases identified as fentanyl-related drug overdoses. The number of fentanyl-related deaths has increased over the past 20 years, corresponding to both statewide increases in the medical use of fentanyl and the abuse of prescription opioids. The demographics of these fentanyl-related overdoses showed that subjects were more likely to be female, white non-Hispanic, and older than those in previously described overdose deaths. Several cases were identified with central and peripheral blood samples and antemortem and postmortem samples available for fentanyl quantification. Given the uncharacteristic demographics of fentanyl-related deaths and the complexity of the laboratory analysis of fentanyl, forensic scientists must use caution in both the detection and interpretation of fentanyl concentrations.

Although many suicide prevention programs focus on youth suicides, data indicate the vast majority of suicides occur among adults (18-64 years). In 2005 New Mexico joined the Centers for Disease Control and Prevention's National Violent Death Reporting System, collecting data on suicides, homicides, and unintentional firearm fatalities to better inform state and national prevention programs. We utilized data collected by the New Mexico Violent Death Reporting System in its first 2 years of operation (2005 and 2006) in order to define the demographic patterns of adult suicides in the state and characterize risk factors. A total of 526 suicides occurred among adults during this time, with the majority being male (78.5%) and White non-Hispanic (56.7%). The highest incidence was in adults between 45 and 54 years (28.1%). Firearms were the most commonly used mechanism, and "current depressed mood" the most commonly identified risk factor. High rates of adult suicide indicate the need for targeted prevention programs.

We retrospectively reviewed autopsy records at a statewide medical examiner's office in order to identify and characterize deaths due to child abuse. In a 6-year period in New Mexico, the medical examiner investigated 45 deaths determined to be child abuse-related. Decedents were predominantly male (68.9%), Hispanic White (53.3%), and all were 5 years of age or younger, with a median age of 1 year. Head injuries were the most common cause of death (44.4%), followed by battered baby syndrome (15.6%). Relatives were involved as alleged perpetrators in 80% of the cases, with the father most often implicated (36.1% of cases), and 88.9% of child abuse injuries resulting in death occurred in the family's residence. Toxicology was positive in 26.7% of cases, but only two cases had substances of abuse present. Information on risk factors such as prematurity, parental age, and history of abuse was also collected.

Recent organ retention scandals and law suits have created a focus on the practice of saving postmortem tissues for extended examination or research purposes. The New Mexico Office of the Medical Investigator (OMI) established a policy to notify families about organ retention and the subsequent disposition of the tissue. The OMI examined the success of this policy in regards to the retention of brains for extended examination by analyzing data abstracted from verbal consent forms from 2003 to 2006. During this time, 715 cases were identified as needing an extended examination of the brain. The percentages of brains saved in any given year, as a percent of the total number of autopsies performed that year, were: 2003 6.5%, 2004 10.4%, and 2005 11.8%. The disposition was cremation in 79% of cases, release with the body after a determined period of time in 14%, and cut fresh in 4%. In conclusion, the instigation of a policy on the verbal notification of the next of kin when organs are retained can be successfully implemented.

Medical examiner files from 1990 through 2004 were reviewed to identify fatalities caused by drivers traveling the wrong direction on interstate highways and identify risk factors and prevention strategies. Other fatal nonpedestrian interstate motor vehicle crashes served as a comparison group. Data abstracted included decedent demographics, driver/passenger status, seatbelt use, blood alcohol concentration, weather and light at time of occurrence and types of vehicles involved. Of 1171, 79 (6.7%) interstate motor vehicle fatalities were because of drivers traveling against the posted direction in 49 crashes, with one to five fatalities per crash. Wrong-way collisions were significantly more likely to occur during darkness (p < 0.0001) and involve legally intoxicated drivers (p < 0.0001). In 29/49 (60%) wrong-way crashes, alcohol was a factor. Prevention strategies aimed at reducing the incidence of driving while intoxicated, as well as improved lighting and signage at ramps, could help reduce the occurrence of fatal wrong-way collisions on interstates.

It has been theorized that drug abusers recently released from prison have an increased risk of fatal drug overdose. The objective of this study was to determine whether persons released from prison in the state of New Mexico have an increased risk of death due to unintentional drug overdose in the time immediately after release from prison. A total of 96 people were identified who had been released from prison and subsequently suffered an unnatural death in 2001 through 2003. Among those who had drug-caused deaths, there was a significantly increased risk of dying in the first 2 weeks after release versus the subsequent 10 weeks RR = 3.08 (P < 0.001, 95% CI: 1.83-5.16). For those who died in the first 2 months after release, there was an increased risk of fatal drug overdose compared with dying of other unnatural causes (P = 0.025). Of those who died of fatal drug overdoses within the first 2 months, the average incarceration time was significantly longer than those who lived longer than 2 months after release (P = 0.021) and they were more likely to have used opiates (P < 0.0001) and sedatives (P = 0.01). Prisoners are at an increased risk of a fatal unintentional drug overdose immediately after release. The time surrounding release provides an opportunity for education on the risks of accidental overdose and the development of interventions to mitigate these risks.
