Point of Care Ultrasound (POCUS) in Bedside Diagnosis of Pyomyositis  

Olusegun Oduyoye, MBBS, MSc, FHEA, FRCPE; Euan Thomas, BSc, MSc
– 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].

The Takotsubo Syndrome: Clinical Diagnosis Using POCUS  

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.

Avulsion Fracture of the Anterior Superior Iliac Spine in a Young Athlete Detected by Point-Of-Care Ultrasound  

Takaaki Mori, MD, MRCPCH, MSc; Takateru Ihara, MD; Osamu Nomura MD, MA, PhD – Pelvic avulsion fractures (PAFs) are rare and specific to adolescents and young athletes [1, 2]. Owing to their stage of musculoskeletal development, forceful contractions of muscles or tendons during sports activities frequently cause a PAF to occur in any of four anatomical sites, including the iliac crest, anterior superior iliac spine (ASIS), anterior inferior iliac spine (AIIS), and ischial tuberosity [1, 2].

Recovery of Severe Acute Kidney Injury in a Patient with COVID-19: Role of Lung Ultrasonography

Varun Madireddy, MD; Daniel W. Ross, MD MPH; Deepa A. Malieckal, MD; Shamir Hasan, DO;  Azzour Hazzan, MD;  Hitesh H. Shah, MD – Acute kidney injury (AKI) is recognized as a complication of COVID-19 among hospitalized patients. Lung ultrasonography (LUS) can be a useful tool in the management of COVID-19 pneumonia when interpreted correctly. However, the role of LUS in management of severe AKI in the setting of COVID-19 remains to be defined.

Point of Care Ultrasound in Monitoring of Post-Renal Biopsy Bleeding

Natalie N. McCall, MD; Anna Burgner, MD, MEHP – A 32-year-old male presented with hypertensive emergency and features of thrombotic microangiopathy. He underwent a kidney biopsy after renal dysfunction persisted despite clinical improvement otherwise. The kidney biopsy was performed with direct ultrasound guidance.

POCUS Evaluation in Acute Kidney Injury

Vanessa A. Hoytfox, MD; Brittney C. Ward, DO; Emily J. Cox PhD; Kang X. Zhang MD FACP – Acute kidney injury is a common clinical problem encountered in general internal medicine. The evaluation of acute kidney injury is mainly driven by the patient’s clinical history, physical exam, and laboratory investigation including urinalysis and urine sediment examination. Point of care ultrasound (POCUS) may be a useful tool to help clinicians to narrow and/or prioritize differential diagnosis in patients presenting with acute kidney injury.

Real-time Point-of-care Ultrasound for the Diagnosis and Treatment of Testicular Torsion

Rahul V. Nene, MD, PhD; Rachna Subramony, MD; Michael Macias, MD; Colleen Campbell, MD; Amir Aminlari, MD – Testicular torsion is a surgical emergency that needs prompt diagnosis and treatment. Point-of-Care ultrasound (POCUS) can not only establish the diagnosis but also guide the Emergency Physician in evaluating the response to manual detorsion.
