Ureteral stones are a common diagnosis in the emergency department (ED) setting, often found with computed tomography (CT). The high frequency of phleboliths can confound ureteral stone diagnosis on CT imaging. ⋯ Phleboliths are a common finding on CT imaging. Radiological findings of rim sign and comet tail sign may help to differentiate phleboliths and ureteral stones; however, their low sensitivity and inconsistent presentation should prompt greater reliance on other signs of ureteral obstruction to aid in diagnosis of undifferentiated pelvic calcifications.

An accurate estimation of fetal gestational age is essential for the management of pregnant patients who present to the emergency department (ED). Point-of-care-ultrasound (POCUS) is an integral part of emergency medicine training and includes measurement of fetal gestational age by the biparietal diameter (BPD) method. ⋯ This study shows that EP-performed BPD measurements for gestational age are quantitatively accurate, with 91% of estimates within 14 days of a standard radiological or obstetrical estimation.

Observational Study
Chest Compression Fraction Alone Does Not Adequately Measure Cardiopulmonary Resuscitation Quality in Out-of-Hospital Cardiac Arrest.
High-quality cardiopulmonary resuscitation in out-of-hospital cardiac arrest is important for increased survival and improved neurological outcome. Chest compression fraction measures the proportion of time chest compressions are given during a cardiac arrest resuscitation. Chest compression fraction has not been compared with the quality of chest compressions delivered at the recommended rate and depth of 100-120/min and 2.0-2.4 inches, respectively. ⋯ Chest compression fraction is not associated with compressions in target for rate and depth for out-of-hospital cardiac arrest cardiopulmonary resuscitation.
