BACKGROUND: Ultrasound is a non-invasive and readily available tool that can be prospectively applied at the bedside to assess muscle mass in clinical settings. The four-site protocol, which images two anatomical sites on each quadriceps, may be a viable bedside method, but its ability to predict musculature has not been compared against whole-body reference methods. Our primary objectives were to (i) compare the four-site protocol's ability to predict appendicular lean tissue mass from dual-energy X-ray absorptiometry; (ii) optimize the predictability of the four-site protocol with additional anatomical muscle thicknesses and easily obtained covariates; and (iii) assess the ability of the optimized protocol to identify individuals with low lean tissue mass...

BACKGROUND Lienalis steal syndrome is a rare complication after orthotopic liver transplantation leading to severe complications. Routine duplex sonography allows early and safe detection of lienalis steal syndrome and secondarily helps to monitor the outcome by evaluating the hemodynamics. MATERIAL AND METHODS This analysis included eight patients who after orthotopic liver transplantation needed splenic artery embolization due to lienalis steal syndrome. Lienalis steal syndrome was assumed in case of elevated transaminases, bilirubinemia or persistent ascites, and the absence of further pathologies...

In their introduction, Gungor et al described ultrasound as a technique for evaluation of patients with low prior probability of acute appendicitis. This testing protocol for appendicitis is being proposed to challenge and perhaps replace the current standard of care for imaging, CT scanning. Specificity of CT scanning is reported in the range of 92-98% and CT is generally felt to be more accurate than ultrasonography The finding of 95.8% specificity for their method appears competitive and may be arithmetically correct but is seriously flawed...

BACKGROUND: Reducing the incidence of indwelling urinary catheter (IUC) use and early removal of the devices that are inserted are appropriate priorities for quality patient care. Just like symptomatic bacteriuria, failed catheter removal as a complication of IUC use is associated with considerable morbidity. In the ideal setting, patients that need IUCs have them, and patients that do not need them will have them safely removed, with the goal of reducing medical complications and facilitating the rehabilitation phase of care...

BACKGROUND: Current evidence supports the utility of simulation training for bedside procedures such as ultrasound-guided jugular central venous catheter (CVC) insertion. However, a standardized methodology to teach procedural skills has not been determined yet. The aim of this study was to evaluate the effectiveness of a simulation-based training program for improving novice technical performance during ultrasound-guided internal jugular CVC placement. METHODS: Postgraduate year 1 (PGY-1) residents from anesthesiology, emergency medicine, cardiology, ICU, and nephrology specialties were trained in four deliberate practice sessions...

Current methods for intra-surgical guidance to localize metastases at cancer surgery are based on radioactive tracers that cause logistical challenges. We propose the use of a novel ultrasound-based method, magnetomotive ultrasound (MMUS) imaging that employ a nanoparticle-based contrast agent that also may be used for pre-operative PET/MRI imaging. Since MMUS is radiation free, this eliminates the dependence between pre- and intra-operative imaging and the radiation exposure for the surgical staff. This study investigates a hypothetical clinical scenario of pre-operative PET imaging, combined with intra-operative MMUS imaging, implemented in a sentinel lymph node (SLN) rat model...

The majority of peripherally inserted central catheters (PICCs) are currently inserted with the aid of ultrasound guidance in the middle third of the upper arm. A growing patient population is presenting with challenging vessel access requiring placement of the PICC in the high upper third of the arm. To avoid this suboptimal exit site, a subcutaneous tunneling of the PICC is established away from the axilla to a more appropriate skin exit site. A prospective evaluation was performed in a single facility for all PICC placements from September 2014 to June 2015...

The validity of a diagnostic test can be demonstrated by comparing it to a gold standard test. Sensitivity, specificity, positive and negative predictive values (PPV, NPV), positive and negative likelihood ratios, diagnostic odds ratio, and the area under the ROC curve are the parameters that reflect the discriminative ability of a diagnostic study. Diagnostic accuracy is very sensitive to the characteristics of the study population and it is affected by the prevalence or the spectrum of the disease studied...

Medical approach to patients is a fundamental step to get the correct diagnosis. The aim of this paper is to analyze some aspects of the reasoning process inherent in medical diagnosis in our era. Pathologic signs (anamnestic data, symptoms, semiotics, laboratory and strumental findings) represent informative phenomena to be integrated for inferring a diagnosis. Thus, diagnosis begins with "signs" and finishes in a probability of disease. The abductive reasoning process is the generation of a hypothesis to explain one or more observations (signs) in order to decide between alternative explanations searching the best one...

A retained urethral foreign body is an uncommon presentation in the Emergency Department. The diagnosis and treatment of retained urethral foreign bodies are determined by their size, location, shape, and mobility and often require specialty consultation and operative intervention. In this case of a 74-year-old man with a self-inserted, retained urethral foreign body, we present the utility of a bedside ultrasound to detect the depth, size, and distance from the meatus of the object to guide the approach to extraction of the object at the bedside in the Emergency Department...

OBJECTIVES: Significant muscle wasting develops in critically ill adults, with subsequent worse outcomes. In the pediatric setting, occurrence and effects of muscle wasting are undescribed; this is in part due to a lack of validated, objective methods for assessing muscle wasting. A single measurement of quadriceps femoris thickness has failed to show consistent reproducibility. We hypothesized that averaging repeated measurements could afford good reproducibility to allow for quadriceps femoris thickness decline detection and monitoring...

BACKGROUND: Recent studies suggest that isolated sonographic assessment of the respiratory, cardiac, or neuromuscular functions in mechanically ventilated patients may assist in identifying patients at risk of postextubation distress. The aim of the present study was to prospectively investigate the value of an integrated thoracic ultrasound evaluation, encompassing bedside respiratory, cardiac, and diaphragm sonographic data in predicting postextubation distress. METHODS: Longitudinal ultrasound data from 136 patients who were extubated after passing a trial of pressure support ventilation were measured immediately after the start and at the end of this trial...

Sensitive, specific, and safe bedside evaluation of brain perfusion is key to the early diagnosis, treatment, and improved survival of neonates with hypoxic ischemic injury. Contrast-enhanced ultrasound (US) imaging is a novel imaging technique in which intravenously injected gas-filled microbubbles generate enhanced US echoes from an acoustic impedance mismatch. This article describes contrast-enhanced US imaging in 2 neonates with hypoxic ischemic injury and future directions on developing quantitative contrast-enhanced US techniques for improved characterization of perfusion abnormalities...

BACKGROUND: Percutaneous dilatational tracheostomy (PDT) has become a standard technique for critically ill patients who require long-term ventilation. The most common early post-operative complication is bleeding related to anatomical variation in vasculature. The procedure is performed at the patient's bedside unless this is deemed unsafe and then the accepted alternative is open tracheostomy in the operating room. OBJECTIVES: To evaluate the use of pre-procedural ultrasound to aid in the decision of whether PDT in critical care patients should be performed at the patient's bedside or by open surgical tracheostomy...

INTRODUCTION: There is a variety of tools being used in clinical practice for the prediction of weaning success from mechanical ventilation. However, their diagnostic performances are less than satisfactory. The purpose of this study is to investigate the value of serial changes in diaphragm function measured by ultrasound during the spontaneous breathing trial (SBT) as a weaning predictor. METHODS AND ANALYSIS: This is a prospective observational study conducted in a 10-bed medical emergency intensive care unit (EICU) in a university-affiliated hospital...

Background Malfunction of the peritoneal dialysis catheter is frequently caused by dislocation. The diagnostic approach is classically based on abdomen X-ray together with detailed case history and physical examination. Despite being rarely applied in clinical practice to evaluate catheter misplacement, ultrasound is a noninvasive, radiation-free technique that is potentially useful also to explore reasons for catheter malfunction. Consequently, we aimed to evaluate the diagnostic accuracy of ultrasound to identify peritoneal catheter misplacement...

Esperanza Naredo, Annamaria Iagnocco
Musculoskeletal ultrasound (MSUS) has become a relevant part of rheumatology practice and research. This imaging modality substantially allows us to optimise the management of inflammatory, degenerative and crystal-related musculoskeletal diseases. MSUS is a valuable point-of-care tool to accurately assess intra-articular and periarticular abnormalities involved in rheumatic diseases. Furthermore, MSUS is a bedside aid for guiding accurate and safe musculoskeletal diagnostic aspirations and therapeutic injections...
