Background: We present the case of a patient who presents with a high velocity thoracoabdominal gunshot wound requiring ultramassive transfusion who exhausted the county blood bank requiring adjunctive therapies to balanced blood product transfusion while additional blood products could be obtained. Summary: Thoracoabdominal gunshot wounds carry a high mortality of 14–37 % because of the risk to produce cardiopulmonary, solid organ as well as major vascular injuries (Mandal and Oparah (1989) [1]). Ultramassive transfusion (>20 units of blood product transfusion) also carries high morbidity and mortality and management has generally centered on balanced transfusion (Matthay et al. (2021) [2]). Conclusion: Balanced blood product transfusion reduces mortality for patients requiring ultramassive transfusion but when this is not possible utilization of adjuncts to blood products may temporize resuscitation until additional blood products can be obtained.

A hepatic pseudoaneurysm (HPA) after blunt or penetrating liver injury is an unusual but potentially lethal complication that can develop from an injured hepatic artery branch [1–5]. Endovascular intervention with coil embolization to treat HPA is a safe and effective method and has become the standard first-line treatment, with a success rate achieving 70–100 % [13,14,15]. Infrequently the pseudoaneurysm is fed by collateral vessels and endovascular intervention may be unsuccessful. Other minimally invasive treatment options that can be considered include image guided percutaneous thrombin injection, endovascular placement of covered stents and injection of liquid agents such as fibrin glue [10,11]. We present a case of a young female who developed a post-traumatic persistent hepatic pseudoaneurysm requiring a total of nine interventions, including six endovascular interventions with angiography, three endoscopic procedures for bleeding, one percutaneous injection, and two re-admissions to the hospital. Although she avoided initial operative management, her three-month hospital course can be considered a failure of conservative management of blunt hepatic trauma due to the accrued health care costs and resources. The literature on the management of persistent pseudoaneurysm is limited. The decision to treat a persistent HPA that are found incidentally and stable in size needs further investigation.

Background: We present the case of two brothers with identical mechanisms of injury presenting simultaneously, one with SARS-Cov-2 respiratory failure and the other in hemorrhagic shock. Summary: Healthcare globally and in the United States met novel challenges during the unprecedented severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) health crisis. The effect of SARS-CoV-2 on hospital and health care delivery systems has been widely reported. Elective surgical procedures were suspended; however, trauma and acute care services remained active and faced unique challenges during this pandemic. Trauma patients by their nature of injury require rapid assessment and treatment to include invasive emergency operations. Not only do trauma centers have to adapt to limited resources and new procedures limiting exposure, they are also met with the confounding issue of trauma patients concomitantly presenting with SARS-CoV-2 respiratory illness. Conclusion: Trauma care providers must now contend with SARS-CoV-2 on the differential for patients presenting with trauma. This is demonstrated by our case of two brothers with identical mechanisms of injury presenting simultaneously, one in shock from respiratory failure and the other hemorrhagic.

Sharks possess a variety of pathogenic bacteria in their oral cavity that may potentially be transferred into humans during a bite. The aim of the presented study focused on the identification of the bacteria present in the mouths of live blacktip sharks, Carcharhinus limbatus, and the extent that these bacteria possess multi-drug resistance. Swabs were taken from the oral cavity of nineteen live blacktip sharks, which were subsequently released. The average fork length was 146 cm (±11), suggesting the blacktip sharks were mature adults at least 8 years old. All swabs underwent standard microbiological work-up with identification of organisms and reporting of antibiotic susceptibilities using an automated microbiology system. The oral samples revealed an average of 2.72 (±1.4) bacterial isolates per shark. Gram-negative bacteria, making up 61% of all bacterial isolates, were significantly (p
