Derrick Huang, MD; Jacob Ruzicka, MD; Leoh León, MD; Latha Ganti, MD, MS, MBA, FACEP – Upper extremity acute limb ischemia (ALI) is a limb-threatening and potentially lethal pathology that is most commonly caused by vascular embolization. Outcomes of limb ischemia are time-sensitive due to the correlation between a longer time from symptom onset to intervention with a vastly higher risk of amputation. In this report, point of care ultrasound (POCUS) was utilized to rapidly diagnose a patient with a proximal right brachial artery embolic occlusion, prompting expedited surgical consultation and successful embolectomy.
Figure 3: Axial view of the plain CT thorax showing low density collection in the pectoralis major muscle of the left hemithorax (a) with underlying costochondral junction showing break in cortex (b). – Tuberculosis (TB) remains a global public health concern; most notably in endemic countries where there is a rise in its incidence. Although primary pulmonary involvement accounts for the majority of TB cases, extrapulmonary tuberculosis (EPTB) is rapidly growing in high income countries.
Sydney Murray, BSc; Krista Trinder, MSc; Linden Kolbenson, MD; Jeremy Katulka, MD; Paul Olszynski, MD, MEd – Feedback on Point of Care Ultrasound (POCUS) skills is essential for skill development. Providing feedback can be difficult in a large province with several distributed medical education sites. Use of handheld POCUS devices and a cloud-based image archiving enables virtual supervision. We evaluated the quality of uploaded images as well as feedback provided to students.
Samantha A. King, MD; Alexis Salerno, MD; Jessica V. Downing, MD; Zachary R. Wynne, MD; Jordan T. Parker, MD; Taylor E. Miller, MD; Semhar Z. Tewelde, MD – Emergency and critical care physicians frequently encounter patients presenting with dyspnea and normal left ventricular systolic function who may benefit from early diastolic evaluation to determine acute patient management. The current American Society of Echocardiography Guidelines approach to diastolic evaluation is often impractical for point of care ultrasound (POCUS) evaluation, and few studies have evaluated the potential use of a simplified approach.
Katie Rong, MD; Grace Lee, BS; Meghan Kelly Herbst, MD – Implementation of point-of-care ultrasound (POCUS) in undergraduate medical education (UME) has increased due to a growing appreciation for its value to students as a tool for learning anatomy, enhancing data acquisition during the physical exam, and formulating a diagnosis.
Melissa Bouwsema, MD; Colin Bell, MD – A 51-year-old man with a history of nephrolithiasis presented to the Emergency Department after a sudden onset of left-sided groin pain and syncope. At presentation, he described his pain as similar to prior renal colic episodes. At his initial assessment, point of care ultrasound (POCUS) was used, which revealed findings consistent with obstructive renal stones, as well as a substantially enlarged left iliac artery.

– Pyomyositis is an acute bacterial infection of skeletal muscle that results in localised abscess formation presenting with symptoms, including pain, swelling, erythema, and fever. It is usually associated with tropical climates; however, there has been an increasing number of cases presenting with pyomyositis in patients with a history of intravenous drug use [1-3].
Josu López Libano, MD; Lorenzo Alomar Lladó, MD; Leire Zarraga López – Takotsubo syndrome is a cardiomyopathy that can mimic an acute heart attack, in terms of clinical presentation, electrocardiographic changes, and findings on echocardiogram. Point-of-care-ultrasound (POCUS) can be used to detect this condition, even though the definitive diagnosis is made angiographically.
Michelle Fleshner, MD MPH; Steve Fox, MD; Thomas Robertson, MD; Ayako Wendy Fujita, MD; Divya Bhamidipati, MD; Thuy Bui MD – Point-of-care Ultrasound (POCUS) is particularly useful in low-middle income countries (LMICs) where advanced imaging modalities and diagnostics are often unavailable. However, its use among Internal Medicine (IM) practitioners is limited and without standard curricula. This study describes POCUS scans performed by U.S. IM residents rotating in LMICs to provide recommendations for curriculum development.
