Suicide by explosion is rare outside of the context of terrorist activities. We present a case of a man with a history of explosives expertise who committed suicide by bomb/decapitation. The case serves to remind forensic pathologists of several important issues when presented with a case involving explosives, such as ensuring the safety of all those involved in the investigation and the importance of interagency cooperation. Potentially invaluable ancillary tests at autopsy include performing radiology, collecting trace evidence, retaining clothing, ensuring the positive identity of the decedent, and recognizing the importance of documenting injury types and patterns.

The phenomenon referred to as "tandem bullets" occurs when two (or more) projectiles are expelled from a firearm barrel in a single pull of the trigger. A "tandem gunshot wound" occurs when tandem bullets produce injuries. Several scenarios can occur, including the occurrence of multiple entrance wounds produced by separate tandem projectiles as well as a single entrance wound through which multiple tandem projectiles enter the body. We present a case of homicide by tandem bullets in which two tandem bullets entered a single entrance wound, with one projectile exiting the body and one remaining within the body. In addition, we review the topic of tandem projectiles and summarize other situations that may cause initial confusion when attempting to account for all gunshot wounds on the skin and projectiles as viewed on pre-autopsy imaging.

Objective: Provide justification for the collection and reporting of urgent care (UC) data for public health syndromic surveillance.Introduction: While UC does not have a standard definition, it can generally be described as the delivery of ambulatory medical care outside of a hospital emergency department (ED) on a walk-in basis, without a scheduled appointment, available at extended hours, and providing an array of services comparable to typical primary care offices.1 UC facilities represent a growing sector of the United States healthcare industry, doubling in size between 2008 and 2011.1 The Urgent Care Association of America (UCAOA) estimates that UC facilities had 160 million patient encounters in 2013.2 This compares to 130.4 million patient encounters in EDs in 2013, as reported by the National Hospital Ambulatory Medical Care Survey.3 Public Health (PH) is actively working to broaden syndromic surveillance to include urgent care data as more individuals use these services.4 PH needs justification when reaching out to healthcare partners to get buy-in for collecting and reporting UC data.Description: The International Society for Disease Surveillance (ISDS) Community of Practice (CoP) platform was used to host a webinar introducing the topic of urgent care participation in syndromic surveillance. This webinar provided a valuable opportunity to obtain insight from jurisdictions pursuing and using UC data. A workgroup was formed to create documentation justifying the collection and reporting of UC data. Using this forum, the workgroup brought together partners from various jurisdictions working with UC data to participate in a literature review of SCOPUS, PubMed, and the Online Journal of Public Health Informatics publications and to share their experiences. These two main sources of information – previous literature and jurisdictional experience – were combined and condensed to provide tangible justifications for the collection and use of UC data.While the workgroup found little in the literature to justify the collection of UC data as a part of syndromic surveillance, the shared experiences of the CoP jurisdictions working to onboard UC facilities provided valuable insight. From this collaborative response, three main reasons to collect UC data were identified.1) Healthcare reform is directing patients away from EDs and toward UC facilities. UC represents reduced cost and more efficient patient processing, thus easing the burden on both patient and healthcare system (according to a 2016 American Academy of Pediatrics article entitled “Urgent Care and Emergency Department Visits in the Pediatric Medicaid Population”). If syndromic surveillance does not adapt to include UC data, the potential exists to lose significant patient populations, which may lead to decreased situational awareness.2) According to the Centers for Medicare and Medicaid Services Stage 3 guidance, Meaningful Use (MU) will change the relationship between eligible professionals (EPs) and syndromic surveillance by restricting EPs to those who practice in a UC facility. This approach to EP participation simplifies the syndromic surveillance MU objective, thereby making it easier for PH jurisdictions to onboard UC facilities.3) Patients with certain conditions that are acute but non-emergent may report more frequently to an UC facility than to an ED. Broadening syndromic surveillance to include UC facilities may increase reporting of “rare event” encounters, which will lower the relative standard error for statistical calculation. Surveillance efforts for conditions like influenza-like illness and Zika virus may improve substantially with a larger data pool.How the Moderator Intends to Engage the Audience in Discussions on the Topic: The moderator will begin discussion with a brief presentation from the literature review and jurisdictional experience, highlighting three justifications for collecting and reporting UC data. The audience will be divided into 3 groups to discuss and validate 3 additional topics: creation of syndromic surveillance talking points to share with UC facility management, creation of jurisdictional UC facility listings, and UC onboarding best practices. Feedback from the 3 groups will be shared with the whole group, followed by a brief summary of the discussion and recommendations for next steps.

Deaths related to exsanguination are not rare; however, most are related to large-caliber blood vessel or organ disruption. This article reports 2 deaths from external hemorrhage arising from superficial lower extremity trauma in persons with peripheral vascular disease and anticoagulant therapy. The first involved a 78-year-old woman who was found unconscious in her home by a relative, with a plastic bag tied around her left foot and evidence of profuse hemorrhage arising from a left great toenail partial avulsion injury. The second involved a 48-year-old male resident of an adult group home who was involved in a physical altercation with a group home employee, who reportedly kicked the decedent in the right shin, resulting in extensive hemorrhage and death. The cases highlight the fact that lethal exsanguination can occur from superficial trauma. Persons with peripheral vascular disease and those taking anticoagulants may be at particular risk for such deaths.

Deaths occurring in the setting of nonprofessional, vehicle-related, recreational sporting activities occurring on land or in water during warm or winter months represent a diverse group of cases. These deaths tend to involve scenarios where the participants are purposefully attempting to enjoy themselves prior to experiencing sudden, catastrophic accidents resulting in lethal outcomes. Ultimately, many of the deaths are related to the high speed at which these vehicle-related activities normally occur. Three broad categories of factors may play contributory roles in death: human factors, vehicle factors, and environmental factors. A series of selected cases are presented, representing examples of varying activity types, involving motorized and nonmotorized vehicles, land and water activities, and warm weather and cold weather environments. For each case, the various human, vehicle and environmental factors believed to be contributory to the accident are considered, and strategies for prevention of these and similar deaths involving recreational sporting vehicles are presented.
