With the emerging interest in documenting and understanding muscle atrophy and function in critically ill patients and survivors, ultrasonography has transformational potential in measuring muscle quantity and quality. Here, we discuss the importance of quantifying skeletal muscle in the ICU setting. We also identify the merits and limitations of various modalities that are capable of accurately and precisely measuring muscularity. Ultrasound is emerging as a potentially powerful tool for skeletal muscle quantification; however, there are key challenges that need to be addressed in future work to ensure useful interpretation and comparability of results across diverse observational and interventional studies...

Many cancer therapy regimes still rely heavily on the systemic administration of toxic chemotherapeutic agents. Ultrasound contrast agents consisting of microbubbles (MB) have emerged as a drug delivery vehicle to overcome the challenges associated with systemic chemotherapy. Here we describe the development of non-immunogenic, functionalized polylactic acid (PLA) MB for use in targeted cancer therapy. Our previous studies have shown that the balance between acoustic behavior and improved immune avoidance was scalable and successful to different degrees with two different PEGylation methods, and was best achieved using incorporation of PEG-PLA at 5 wt% and for a LipidPEG at 1 wt%...

Acute lower extremity ischemia from septic emboli is a surgical emergency. Timely diagnosis and management are critical to improve patient outcome. However, traditional diagnostic modalities such as intraoperative angiogram are time-consuming, require special equipment and personnel, and introduce contrast exposure for critically ill patients. There are limited reports of utilization of point-of-care ultrasound to detect peripheral septic emboli. We present a case where femoral occlusive septic emboli were identified by point-of-care ultrasound after mitral valve replacement...

Lung ultrasound (LUS) is a valid tool for the assessment of heart failure (HF) through the quantification of the B-lines. This study in HF patients aims to evaluate if LUS: (1) can accelerate the discharge time; (2) can efficiently drive diuretic therapy dosage; and (3) may have better performance compared to the amino-terminal portion of B type natriuretic peptide (NT-proBNP) levels in monitoring HF recovery. A consecutive sample of 120 HF patients was admitted from the Emergency Department (ED) to the Internal Medicine Department (Verona University Hospital)...

Pulmonary ailments are conventionally diagnosed by spirometry. The complex forceful breathing maneuver as well as the extreme cost of spirometry renders it unsuitable in many situations. This work is aimed to facilitate an emerging direction of tidal breathing-based pulmonary evaluation by designing a novel, equitable, precise and portable device for acquisition and analysis of directional tidal breathing patterns, in real time. The proposed system primarily uses an in-house designed blow pipe, 40-kHz air-coupled ultrasound transreceivers, and a radio frequency (RF) phase-gain integrated circuit (IC)...

INTRODUCTION: Small bowel obstruction (SBO) is a common presentation to the Emergency Department (ED). While computed tomography (CT) is frequently utilized to confirm the diagnosis, this modality is expensive, exposes patients to radiation, may lead to time delays, and is not universally available. This study aimed to determine the test characteristics of ultrasound for the diagnosis of SBO. METHODS: PubMed, CINAHL, Scopus, the Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials were assessed for prospective trials evaluating the accuracy of ultrasound for the detection of SBO...

Gliomas are CNS neoplasms that infiltrate the surrounding brain parenchyma, complicating their treatment. Tools that increase extent of resection while preventing neurological deficit are essential to improve prognosis of patients diagnosed with gliomas. Tools such as intraoperative MRI, ultrasound and fluorescence-guided microsurgery have been used in the surgical resection of CNS gliomas with the goal of maximizing extent of resection to improve patient outcomes. In addition, emerging experimental techniques, for example, optical coherence tomography and Raman spectroscopy are promising techniques which could 1 day add to the increasing armamentarium used in the surgical resection of CNS gliomas...

A healthy, functional microcirculation in combination with nonobstructed epicardial coronary arteries is the prerequisite of normal myocardial perfusion. Quantitative assessment in myocardial perfusion and determination of absolute myocardial blood flow can be achieved noninvasively using dynamic imaging with multiple imaging modalities. Extensive evidence supports the clinical value of noninvasively assessing indices of coronary flow for diagnosing coronary microvascular dysfunction; in certain diseases, the degree of coronary microvascular impairment carries important prognostic relevance...

BACKGROUND: Dyspnea is one of the most frequent causes of admission in Internal Medicine wards, leading to a sizeable utilization of medical resources. STUDY DESIGN AND METHODS: The role of bedside lung ultrasound (LUS) was evaluated in 130 consecutive patients (age: 81±9years), in whom blindly collected LUS results were compared with data obtained by clinical examination, medical history, blood analysis, and chest X-ray. Dyspnea etiology was classified as "cardiac" (n=80), "respiratory" (n=36) or "mixed" (n=14), according to the discharge diagnosis (congestive heart failure either alone [n=80] or associated with pneumonia [n=14], pneumonia [n=24], and obstructive disventilatory syndrome [n=12])...

BACKGROUND AND STUDY AIMS:  Walled-off pancreatic necrosis (WOPN) represents the major risk factor for sepsis-related multiple organ failure. Surgical debridement is an invasive approach associated with high rates of adverse events (AEs) and death. As an alternative, endoscopic ultrasound-guided cysto-gastro-anastomosis has emerged as an effective treatment for WOPNs. Recently a new dedicated-lumen apposing metal stent (LAMS) has been used with satisfactory results in treating peri-pancreatic fluid collections, including WOPNs...

Optoacoustic imaging emerged in early 1990s as a new biomedical imaging technology that generates images by illuminating tissues with short laser pulses and detecting resulting ultrasound waves. This technique takes advantage of the spectroscopic approach to molecular imaging, and delivers high-resolution images in the depth of tissue. Resolution of the optoacoustic imaging is scalable, so that biomedical systems from cellular organelles to large organs can be visualized and, more importantly, characterized based on their optical absorption coefficient, which is proportional to the concentration of absorbing chromophores...

Pericardiocentesis is a rare life-saving procedure for patients with cardiac tamponade. Due to the infrequency of this procedure, simulation models are often used for training. Commercial models are generally expensive. Proposed homemade models offer a lower-cost alternative but can be labor and time intensive. The purpose of this study was to determine the feasibility of a limited use, low-cost ultrasound-guided pericardiocentesis model as a training tool for emergency physicians. Our model proved to be a practical, easily implemented, and acceptable model for training emergency physicians, including residents and students, in ultrasound-guided pericardiocentesis...

Pediatric emergency medicine physicians may be able to use point-of-care ultrasound (POCUS) as a tool to evaluate abdominal wall masses. We present a case of a 2-month-old infant with a lower abdominal mass identified as a hernia sac by POCUS. It was initially thought to represent a Spigelian-type abdominal wall hernia but subsequently determined to be an unusual presentation of an inguinal hernia with testicular entrapment. We review each of these diagnoses in addition to relevant POCUS findings.
