The relationship between intraosseous catheter tip placement, flow rates, and infusion pressures in a high bone density cadaveric swine () model.

Background: Intraosseous (IO) infusion is a life-preserving technique when intravenous access is unobtainable. Successful IO infusion requires sufficiently high flow rates to preserve life but at low enough pressures to avoid complications. However, IO catheter tips are often misplaced, and the relative flow rates and pressures between IO catheter tips placed in medullary, trabecular, and cortical bone are not well described, which has important implications for clinical practice.

Technology-enhanced simulation in emergency medicine: Updated systematic review and meta-analysis 1991-2021.

Background: Over the past decade, the use of technology-enhanced simulation in emergency medicine (EM) education has grown, yet we still lack a clear understanding of its effectiveness. This systematic review aims to identify and synthesize studies evaluating the comparative effectiveness of technology-enhanced simulation in EM.

Methods: We searched MEDLINE, EMBASE, PsycINFO, CINAHL, ERIC, Web of Science, and Scopus to identify EM simulation research that compares technology-enhanced simulation with other instructional modalities.

Ultrasound-guided Percutaneous Cryoneurolysis to Treat Chronic Postamputation Phantom Limb Pain: A Multicenter Randomized Controlled Trial.

Background: Postamputation phantom pain is notoriously persistent with few validated treatments. Cryoneurolysis involves the application of low temperatures to reversibly ablate peripheral nerves. The authors tested the hypothesis that a single cryoneurolysis treatment would decrease phantom pain 4 months later.

Accidental organophosphate poisoning: A case series of 2 pediatric coumaphos exposures.

Introduction: Pediatric organophosphate insecticide poisonings are rare in the United States, and life-threatening toxicity is rarely seen. We report 2 accidental ingestions of the organophosphate insecticide coumaphos that resulted in life-threatening symptoms.

Case Reports: A 7-year-old boy and 10-year-old girl both presented from home after accidental ingestion of 1 "spoonful" of coumaphos 20% liquid (Asuntol; Bayer de Mexico, S.

Electric scooter craniofacial trauma.

Objective: The use of standing electronic scooters associated with micromobility applications (e-scooters) has risen nationally. The aim of this study was to obtain a detailed view of soft tissue and bony craniofacial injury associated with e-scooter-related trauma.

Methods: Single-institution retrospective case series of patients presenting to a level 1 trauma center emergency department or trauma unit with documented e-scooter-related craniofacial injury.

Male Slings for Post-prostatectomy Incontinence.

Stress urinary incontinence following radical prostatectomy can have a significant impact on a man's quality of life. Male slings offer a perceived minimally invasive treatment option and do not require the manual dexterity necessary to operate an artificial urinary sphincter. In this review, we outline the history of male slings and discuss the various fixed and adjustable slings that are available on the market.

Postoperative EEG association with seizure recurrence: Analysis of the NIH epilepsy surgery database.

The epilepsy surgery database from 1984 to 2012 at the National Institutes of Health (NIH) was reviewed to determine the association of postoperative electroencephalography (EEG) with seizure recurrence. Eighty-three patients were analyzed, with 41 having at least 5 years of follow-up. The relationship between epileptiform postoperative EEG findings and seizure recurrence at 1, 2, and 5 years was not significant, despite a significant decrease in abnormal EEG recordings after surgery.

An elderly woman with a mediastinal granulosa cell tumour: a rare presentation.

Mediastinal lesions occur in a wide variety of clinical conditions. Metastatic granulosa cell tumour (GCT) in the mediastinum is a rare occurrence. We report a case of a woman who had a metastatic (GCT) in her mediastinum 40 years after treatment of the initial neoplasm.

Central nervous system Tuberculosis in a man from Cambodia with worsening headaches.

Central nervous system (CNS) tuberculosis should be considered in patients from endemic nations with worsening neurological symptoms. If imaging reveals possible CNS tuberculomas, potentially life-threatening lesions should be excised and analyzed. When disease is less severe, other tissues possibly infected should be biopsied first for diagnosis to avoid neurosurgery.

Use of Social Media in Emergency Ultrasound Fellowship Programs.

Objective: Social media has been gaining traction among learners and educators for its ability to stimulate discussion, increase participation, and promote knowledge sharing. Despite the growing research around the benefits of social media in education, there is little evidence on how it is being incorporated into emergency ultrasound (EUS) fellowships. This study aims to determine the preference and use of social media by engaging with program directors across EUS programs in the United States to assess the current landscape of and attitudes toward social media use.

Bilateral testicular infarction and orchiectomy as a complication of polyarteritis nodosa.

We report an unusual case of a 28-year-old male with constitutional symptoms and bilateral testicular pain. After diagnosis of cytomegalovirus (CMV) hepatitis, his constitutional symptoms and testicular pain worsened despite treatment for epididymoorchitis. Ultrasound was concerning for infarction.

History of U.S. military contributions to the study of diarrheal diseases.

Diarrhea, a scourge upon humanity since preliterate times, has been the particular nemesis of military forces. The Armed Forces of the United States have been in the forefront in the diagnosis, treatment, and prevention of diarrheal illness. U.

Coccidioidomycosis of the prostate gland: two cases and a review of the literature.

Coccidioidomycosis prostatitis is an uncommon presentation of disseminated coccidioidomycosis, a fungal disease endemic in the southwestern United States. Coccidioidomycosis prostatitis should be considered in the differential diagnosis of a patient from an endemic region with evidence of persistent sterile pyuria, prostatitis, or granulomatous disease of the prostate. Diagnosis is established by biopsy, and treatment includes either an azole or amphotericin B.
