“…Air surrounding the perirenal space prevents the transduction of sound waves resulting in artifacts, decreased visualization of deeper structures and an obscure outline of the kidney[ 43 ]. A-lines (Figure 4A ) and B-lines (Figure 4B ) are basic signs on lung ultrasound for the diagnosis of acute respiratory failure[ 47 ]. Both are artifacts generated when air is struck by ultrasound beams.…”

BACKGROUND Emphysematous pyelonephritis (EPN) is a rare but fatal necrotic infection of the kidney, which usually leads to septic shock. Therefore, early diagnosis and optimized therapy are of paramount importance. In the past two decades, point-of-care ultrasound (POCUS) has been widely used in clinical practice, especially in emergency and critical care settings, and helps to rapidly identify the source of infection in sepsis. We report a rare case in which a “falls” sign on POCUS played a pivotal role in the early diagnosis of EPN. CASE SUMMARY A 57-year-old man presented with fever and lumbago for 3 d prior to admission. He went to the emergency room, and the initial POCUS detected gas bubbles in the hepatorenal space showing a hyperechoic focus with dirty shadowing and comet-tail artifacts. This imaging feature was like a mini waterfall. His blood and urine culture demonstrated Escherichia coli bacteremia, and EPN associated with septic shock was diagnosed. The patient did not respond to broad-spectrum antibiotic treatment and a perirenal abscess developed. He subsequently underwent computed tomography-guided percutaneous catheter drainage, and fully recovered. We also review the literature on the sonographic features of POCUS in EPN. CONCLUSION This case indicates that a “falls” sign on POCUS facilitates the rapid diagnosis of severe EPN at the bedside.

“…Other models require access to uncommon technology such as 3D printers, access to cadavers, or may not be compatible with US‐guidance 17 . However, many inexpensive materials have been shown to provide accurate simulation for US training 15,17–20 . Our aims were to design an educational model that effectively and efficiently allowed users to improve their comfort and expertise in US‐guided injections in the posterior GHJ space.…”

ObjectivesUltrasound‐guided injections are used to treat common shoulder pathologies and have been shown to be more accurate and effective than traditional landmark‐guided procedures. Currently, there exists no inexpensive shoulder model that accurately simulates the anatomical structures of the shoulder while also facilitating glenohumeral joint (GHJ) injection. Our model is an alternative to the traditional bedside training and provides a low‐risk training environment.MethodsWe created this model from easily accessible materials. Polyvinyl chloride pipe was used to create the skeletal infrastructure pectoral girdle. A detergent pod was used to represent the GHJ space. Steaks were used to simulate the infraspinatus and deltoid muscles, with meat glue as a fascial layer between the two simulated muscles. Total cost of materials for the model was $19.71.ResultsOur model successfully replicates known anatomical features of the GHJ. Additionally, the model facilitates injection into a GHJ space, representing a GHJ injection. Our model was replicated to train medical student practitioners during five different educational sessions. The model was validated through comparison to standardized educational ultrasound training videos. It was further validated by ultrasound experts.ConclusionsThe shoulder model we created is effective in simulating GHJ injections under ultrasound guidance. It simulates realistic muscle and bony landmarks both for ultrasound imaging and injection feel. Importantly, it is inexpensive and easy to replicate allowing more access to medical practitioners and students to be educated on the procedure.

BackgroundUltrasound is becoming more widely utilized in clinical practice; however, its effectiveness is limited by the operator's skills. Simulation models are attractive options for developing skills because they allow inexperienced users to practice without the risk of endangering patients. ObjectiveThe purpose of this study was to identify commercially available and homemade ultrasound models to describe them in terms of materials, cost, and whether they are high-or low-fidelity for medical student education. MethodsThis is an investigational study on cost-effective ultrasound training methods for medical students. Our study was performed using search engines in Google, Google Scholar, and PubMed to search for models for the following five modalities: foreign body identification, intravenous (IV) injection training, abdominal ultrasound, ocular ultrasound, and ultrasound-guided lumbar puncture training. ResultsMost homemade models for foreign body identification, IV injection training, and ocular ultrasound could be created for less than $20. IV injection training models were the cheapest commercially available models. There are multiple commercially available options for abdominal ultrasound models, but no options were found for homemade construction. The construction cost for lumbar puncture models was larger due to the need to purchase an anatomically accurate set of lumbar vertebrae. ConclusionsThis study provides initial guidance and suggestions for ultrasound training models that are currently available. Ultrasound models that can be cheaply made or purchased increase accessibility for medical students to gain early exposure in a cost-effective and safe manner.
