Texas Bull Nettle (Cnidoscolus texanus) Exposures Reported to Texas Poison Centers.
Texas bull nettle (Cnidoscolus texanus) is covered in bristly hairs similar to stinging nettle. Contact with the plant may result in intense dermal pain, burning, itching, cellulitis, and allergic reaction. This study characterizes C texanus exposures reported to a large state-wide poison center system. ⋯ C texanus exposures reported to Texas poison centers were most likely to be unintentional and occur at the patient's own residence. The outcomes of the exposures tended not to be serious and could be managed successfully outside of health care facilities.

Prolonged field care (PFC) has emerged as a recent area of focus for US military Special Operations Forces (SOF) medical experts. Focused on the current reality of providing medical care to military forces often deployed in remote and austere locations far from medical support or a robust casualty evacuation chain, PFC encompasses evolving operational situations not unlike many wilderness medicine practice environments. SOF currently operates in all areas of the world and on a variety of different missions, which finds these small teams far from the accustomed practice environment of robust deployed medical infrastructure commonly seen during the last 15 years of military conflicts. ⋯ The approach to training and educating SOF medics on PFC is based on defined capabilities and operational situations that incorporate best medical practices and seeks to place advance resuscitative capabilities into the hands of providers closest to the point of injury. By transitioning from an approach solely driven by acute trauma aide, incorporating the best practices of Tactical Combat Casualty Care (TCCC), PFC builds upon best practices for the continuing management of both medical and trauma patients in wilderness environments. PFC incorporates best practices in generally hospital-based management of serious and critical casualties to decrease both mortality and morbidity in austere, prehospital operational settings.

ReviewJunctional Hemorrhage Control for Tactical Combat Casualty Care.
During historic, as well as more recent, conflicts, most combat casualties who die from their injuries do so in the prehospital setting. Although many of the injuries incurred by these casualties are nonsurvivable, a number of injuries are still potentially survivable. Of those injuries that are potentially survivable, the majority are truncal, junctional, and extremity hemorrhage. ⋯ The objective of this article is to provide an updated review of junctional hemorrhage control efforts and devices as they apply primarily to military prehospital trauma management and Tactical Combat Casualty Care and to prompt further consideration and application of these devices in nonmilitary prehospital, austere, and wilderness environments. Four junctional tourniquets are currently cleared by the Food and Drug Administration (FDA) for junctional hemorrhage control, and 1 junctional tourniquet is also FDA-cleared for pelvic stabilization. As junctional hemorrhage control efforts progress, scientists need to continue to conduct research and clinicians need to continue to monitor the performance of junctional tourniquets, especially in conjunction with morbidity and mortality outcomes, for both military and civilian trauma patients.

ReviewTreatment of Thoracic Trauma: Lessons From the Battlefield Adapted to All Austere Environments.
Severe thoracic trauma in the backcountry can be a formidable injury pattern to successfully treat. Traumatic open, pneumo-, and hemothoraces represent some of the most significant patterns for which advanced equipment and procedures may help leverage morbidity and mortality, particularly when evacuation is delayed and environmental conditions are extreme. This paper reviews the development of successful techniques for treating combat casualties with thoracic trauma, including the use of vented chest seals and the technique of needle thoracentesis. Recommendations are then given for applying this knowledge and skill set in the backcountry.

ReviewThe Care of Thermally Injured Patients in Operational, Austere, and Mass Casualty Situations.
Burn injury affects a half million people in the United States annually. The severe thermal injury can have long-term debilitating effects. The management of burn patients in austere and operational environments is more complex. ⋯ The care of burn patients in austere, operational, and mass casualty situations can tax resources and manpower. The care of these patients will require creativity and ingenuity. Burn patients can be difficult to manage under normal circumstances but the care of these patients under the above situations complicates the management severalfold.
