Welcome to another ultrasound-based case, part of the “Ultrasound For The Win” (#US4TW) Case Series. In this peer-reviewed case series, we focus on real clinical cases where bedside ultrasound changed management or aided in diagnoses. In this case, a 22-year-old man presents with acute scrotal pain.

So many great information can be gleaned from a focused echocardiogram in Emergency Department patients. What views are you obtaining? What is the importance of the e-point septal separation (EPSS) and how to measure this? Drs. Jimmy Fair, Mike Mallon, and Mike Stone provide a terrific step-by-step image-based guide to these questions that you can use at the bedside as a refresher.

Traditionally in medical school, it is taught that lower extremity deep tendon reflexes for L4 and S1 nerve root levels can be elicited by tapping on the patella and Achilles tendons. It was just taught that L5 didn’t have a reflex to check. Knowing if an L5 radiculopathy existed would be especially helpful when assessing a patient for a potential lumbar disc herniation where a careful lower extremity neurologic exam is important. It turns out one can actually check for a L5 reflex.
60% of patients in the United States who develop severe sepsis are older adults (age 65 and over) [1], and the mortality of severe sepsis increases steadily with age to nearly 40% in those over 85 [2]. There are many factors that make older adults more susceptible to sepsis, and that can also make sepsis more difficult to detect. Here are some tips to help explain why this is, and how you can identify it sooner.
Bedside pulmonary ultrasonography is becoming increasingly popular in the Emergency Department. You can you use it to assess for pneumothoraces, pleural effusion, pneumonia, pulmonary edema, and other etiologies. There are subtle nuances to help you differentiate these diagnoses. What are A-lines and B-lines? This PV card on the focused lung ultrasound by Drs. Anne Aspler, Clare Heslop, and Mike Stone outline some great bedside tips.

When the topic of pericarditis is mentioned, the classic electrocardiogram (ECG) findings of diffuse ST elevation and PR depression are often the focus of discussion. What about the criteria for diagnosis, the 3-prong approach to treatment, and contraindications to colchicine? These are the great questions answered by Dr. Chris Bond (@socmobem) in this PV card, which summarize 3 key papers by Imazio et al from the New England Journal of Medicine, Archives of Internal Medicine, and Circulation.

Ocular injuries and pathology are a common cause for Emergency Department visits. With bedside ultrasonography, many of these conditions can be assessed. Did you know that you can check for a retinal detachment, vitreous hemorrhage, and even a lens dislocation? What do these look like? Check out this great PV card on the focused ultrasound assessment of the eye.
