Multicenter Study
Predictive performance of the common red flags in emergency department headache patients: a HEAD and HEAD-Colombia study.
Only a small proportion of patients presenting to an ED with headache have a serious cause. The SNNOOP10 criteria, which incorporates red and orange flags for serious causes, has been proposed but not well studied. This project aims to compare the proportion of patients with 10 commonly accepted red flag criteria (singly and in combination) between patients with and without a diagnosis of serious secondary headache in a large, multinational cohort of ED patients presenting with headache. ⋯ The sensitivity and specificity of the red flag criteria in this study were lower than previously reported. Regarding clinical practice, this suggests that red flag criteria may be useful to identify patients at higher risk of a serious secondary headache cause, but their low specificity could result in increased rates of CT scanning.

Prompt antimicrobial therapy and source control on survival and defervescence of adults with bacteraemia in the emergency department: the faster, the better.
Bacteraemia is a critical condition that generally leads to substantial morbidity and mortality. It is unclear whether delayed antimicrobial therapy (and/or source control) has a prognostic or defervescence effect on patients with source-control-required (ScR) or unrequired (ScU) bacteraemia. ⋯ Regardless of the need for source control in cases of bacteraemia, there seems to be a significant association between the prompt administration of appropriate antimicrobials and both a favourable prognosis and rapid defervescence, particularly among critically ill patients. For ScR bacteraemia, delayed source control has been identified as a determinant of unfavourable prognosis and delayed defervescence. Moreover, this association with patient survival and the speed of defervescence appears to be augmented among critically ill patients.

An 18-year-old male active duty US Army service member presented to the emergency department with a lower leg abscess in the region of a previously debrided methicillin-resistant Staphylococcus aureus abscess. After initial presentation, the patient became hypotensive, exhibited signs of renal failure, and developed a diffuse erythematous rash. Streptococcus pyogenes was grown from intraoperative cultures, and he was diagnosed with Streptococcal toxic shock syndrome (STSS). ⋯ Therefore, it is imperative for physicians to recognize systemic involvement of seemingly isolated extremity infections. We encourage a high index of suspicion in treating bacterial abscesses for possible complications, and close monitoring of patient status. This suspicion should be even higher during outbreaks of bacteria that can cause STSS, much like the patient presented here.

Preservation of life, preservation of limb, and preservation of eyesight are the priorities for military medical personnel when attending to casualties. The incidences of eye injuries in modern warfare have increased significantly, despite personal eye equipment for service members. Serious eye injuries are often overlooked or discovered in a delayed fashion because they accompany other life- and limb-threatening injuries, which are assigned a higher priority. Prehospital military ocular trauma care is to shield the eye and evacuate the casualty to definitive ophthalmic care as soon as possible, with exceptions for treatment of ocular chemical injury and orbital compartment syndrome. Retrospective analysis of eye injuries in recent conflicts identified gaps in clinical capabilities with up to 96% of ocular injuries being suboptimally managed. Ocular compartment syndrome (OCS) is a complication associated with orbital hemorrhage, where significant morbidity occurs as a result of increasing intracompartment pressure. The ischemic tolerance of the retina and optic nerve is approximately 90 minutes, so OCS must be rapidly diagnosed and aggressively treated through lateral canthotomy/cantholysis (LC/C) to prevent permanent vision loss. LC/C procedures consist of using hemostats to crush the lateral canthal fold and cutting the lateral canthal tendon from the inferior crus to relieve increasing intracompartment pressure. The purpose of this study was to examine the baseline capabilities of military physicians and surgeons to accurately and independently perform the LC/C procedures and identify performance gaps that could be closed through focused professional development activities. ⋯ We identified significant performance gaps among emergency medicine physicians, general surgeons, and ophthalmologists in their abilities to recognize and treat OCS through LC/C procedures. These sight-saving procedures are a critical competency for forward-situated clinicians in expeditionary contexts. We identified the need for targeted approaches to professional development for closing the performance gaps for both emergency medicine physicians and general surgeons.
