The primary concern of emergency physicians (EPs) in symptomatic patients in their early pregnancy is to rule out ectopic pregnancy by identifying a definite intrauterine pregnancy (IUP). Then an assessment of viability is required for the IUPs. Although transvaginal ultrasound (TVUS) stands as the best modality for these patients, it is not available in most emergency settings. This study aimed to investigate the effects of high-frequency linear transducers (HFLT) on the accuracy of point-of-care ultrasound (POCUS) for detection of IUP and the agreement between EPs and obstetricians for patients' diagnosis. ⋯ POCUS plus HFLT performed by EPs in evaluating symptomatic patients in their first-trimester pregnancy improves the accuracy to a non-inferior level compared to TVUS performed by obstetricians. Hence, EPs can securely rely on POCUS to confirm IUP and FCA. However, they should be cautious about using it as a rule-out tool. Moreover, HFLT use could enhance the accuracy of POCUS in viability assessment as an alternative to TVUS.

Electrical storm is defined as three or more sustained episodes of ventricular tachycardia, ventricular fibrillation, or appropriate cardioverter-defibrillator shocks during a 24-h period. These patients are notoriously difficult to manage. We present a case secondary to Chagas disease that was responsive to lidocaine. Although an uncommon presentation, given the large-scale population movement from South America, Chagas has an increased incidence and is an important diagnostic consideration in patients with new onset heart failure, arrhythmia, or electrical storm.

The HINTS examination (head impulse, nystagmus, test of skew) is a bedside physical examination technique that can distinguish between vertigo due to stroke, and more benign peripheral vestibulopathies. Uptake of this examination is low among Emergency Medicine (EM) physicians; therefore, we surveyed Canadian EM physicians to determine when the HINTS exam is employed, and what factors account for its low uptake. ⋯ Though HINTS exam usage is common, there is a need for education on when to apply it, and how to do so, particularly as concerns the head-impulse test. Our attached rubric may assist with this, but quality-improvement initiatives are warranted. Low uptake is partly due to the lack of validation of this examination among EM physicians, so effort should be made to conduct well-designed HINTS trials exclusively involving EM physicians.

Dissemination and Use of Point-of-Care Ultrasound by Pediatricians in Europe: A Research in European Pediatric Emergency Medicine Network Collaborative Survey.
We surveyed the dissemination and use of point-of-care ultrasound (POCUS), physician training levels, and barriers and limitations to use of POCUS among pediatricians and pediatric emergency medicine (PEM) physicians across Europe and Israel. ⋯ The dissemination of pediatric POCUS in the European and Israeli centers we surveyed is limited, and its applications are largely restricted to the Focused Assessment with Sonography in Trauma examination. This is likely related to lack of training programs. In contrast, the potential value of use of POCUS in PEM practice is recognized by the majority of respondents.
