BACKGROUND: Muscle wasting is common among critically ill patients with sepsis and has a significant effect on clinical outcome. However, appropriate tool for measurement of muscle loss is debatable. Ultrasonography (USG) has been used for objective assessment of quadriceps muscle thickness among these patients; however, there is limited data on its reliability. AIMS AND OBJECTIVE: This study was aimed to assess the reliability of quadriceps muscle thickness as measured by critical care physicians...

BACKGROUND: The breast surgery community has adopted needle aspiration as the standard of care for breast abscesses, which have a size less than 5 cm on ultrasound, no skin changes, and fewer than 5 days of symptoms. Our acute-care surgery (ACS) service manages all breast abscess consults at our urban safety-net hospital. We undertook this descriptive study to identify the rate of operative incisions and drainage performed by ACS surgeons which were not compatible with best practices for breast abscess management...

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])...

Point-of-care cardiac ultrasound (POCUS) is a common application in Emergency Medicine. Here we present a case of an incidentally discovered dilated right coronary sinus on ultrasound. This case involved a 55-year-old female who presented with chest pain, shortness of breath, and lightheadedness. Her initial presentation was concerning for congestive heart failure (CHF) exacerbation. A bedside ultrasound was performed to assess cardiac function, where a dilated right coronary sinus was discovered. The right coronary sinus is the vein that serves as the venous return for the coronary system...

Intravesical instillation is the main therapy for bladder cancer and interstitial cystitis. However, most drug solutions are eliminated from bladder after the first voiding of urine. To solve this problem, we proposed a floating hydrogel with self-generating micro-bubbles as a new delivery system. It floated in urine, avoiding the urinary obstruction and bladder irritation that ordinary hydrogels caused. In this study, we abandoned traditional gas-producing method like chemical decomposition of NaHCO₃, and used the foamability of Poloxamer 407 (P407) instead...

We report a case of a patient with septic shock who underwent central venous catheter placement in the left internal jugular vein, and a bedside ultrasound 'bubble study' revealed venous cannulation. A chest X-ray postprocedure revealed concern for arterial system catheterisation. However, the possibility of a persistent left superior vena cava was discussed and confirmed with a formal transthoracic echocardiogram and CT. This case demonstrates the importance of ultrasound-guided visualisation of anatomical structures in real time during central venous catheterisation...

BACKGROUND & OBJECTIVES: Securing long-term venous access is an essential part of sick newborn care. The malposition of central line tip leads to several complications. There is a need for an easily available bedside investigating tool to diagnose these malpositions. This study was done to compare the effectiveness of real-time ultrasound (RTUS) with X-ray in identifying the peripherally inserted central catheter (PICC) line tip. METHODS: This pilot observational study was conducted in a level III Neonatal Intensive Care Unit of a tertiary care hospital in India, from June 2012 to June 2013...

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 who need IUCs have them, and patients who do not need them will have them removed safely, 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...
