BACKGROUND Lung ultrasound (LUS) represents an emerging technique for bedside chest imaging in different clinical settings. A standardized approach allows the diagnosis, the quantification, and the follow-up of different conditions for which acute respiratory failure is the main clinical presentation. The aim of this study was to test what skill targets could be achieved in LUS, with a short-tr...

tris(3-bromo-acetylacetonato) chromium(iii) as an inert and very stable complex with a good leaving group was synthesized using as-prepared cr(acetylacetonate)3. highly ordered nanoporous silica (lus-1), with some great features, was functionalized with 3-aminopropyltriethoxysilane. then the as-prepared product was modified with tris(3-bromo-acetylacetonato) chromium(iii) under mild reaction co...

BACKGROUND The aim of this prospective, multicenter study was to define the accuracy of lung ultrasound (LUS) in the diagnosis of community-acquired pneumonia (CAP). METHODS Three hundred sixty-two patients with suspected CAP were enrolled in 14 European centers. At baseline, history, clinical examination, laboratory testing, and LUS were performed as well as the reference test, which was a r...

BACKGROUND Routine intra-operative cholangiography (IOC) during laparoscopic cholecystectomy is often not performed because of increased operative time, radiation, and failure rate. Laparoscopic ultrasound (LUS) is a less invasive alternative but studies comparing it to IOC have been of small sample size. This study aims to assess the diagnostic accuracy of LUS in detecting common bile duct (CB...

A purely optical setup for the coregistration of photoacoustic (PA), ultrasound (US), and speed-ofsound (SOS) section images is presented. It extends a previously developed method for simultaneous PA and laser-US (LUS) pulse-echo imaging with a LUS transmission imaging setup providing two-dimensional (2-D) SOS maps. For transmission imaging, the sound waves traversing the investigated object ar...

IMPORTANCE Lung ultrasonography (LUS) is a bedside technique useful to diagnose neonatal respiratory problems, but, to our knowledge, no data are available about its use for monitoring lung function or eventually guiding surfactant therapy. OBJECTIVE To determine the diagnostic accuracy of a neonatal-adapted LUS score to evaluate oxygenation and predict need for surfactant administration. D...

PURPOSES Bedside lung ultrasound (LUS) is useful in detecting radio-occult pleural-pulmonary lesions. The aim of our study is to compare the value of LUS with other conventional routine diagnostic tools in the emergency department (ED) evaluation of patients with pleuritic pain and silent chest radiography (CXR). METHODS Ninety patients consecutively admitted to the ED with pleuritic pain and...

We report two cases of women with a previous cesarean performed before active labor at 29 weeks of gestation who underwent sonographic measurement of the lower uterine segment (LUS) at 36 weeks' gestation in their subsequent pregnancy. In both cases, uterine scar defect was detected on the upper part of the LUS, at ∼9 to 11 cm from the cervical os, and was only visualized by the transabdominal ...

Techniques aimed at manipulating both sensitivity and response bias in absolute identification of loudness arc cxplorcd in order to illuminate features of two Thurstonian-based models: the range theory of Braida and Durlach and the attention-band theory of Green and Luce. Evidence is first offered that signal range affects both the sensory and the criterion variance in the Braida-Durlach model....
