BACKGROUND The lung is at the crossroads of ventilation and circulation and can provide a wealth of diagnostic information. In the past, lung ultrasound (LUS) was considered impossible. However, the interplay between air, fluid and pleurae creates distinctive artefacts. Combinations of these artefacts can help differentiate between various pathological processes, including pulmonary oedema, pne...

OBJECTIVE To define the role of lower uterine segment (LUS) evaluation at term. DESIGN Observational case-control study. SETTING University hospital. PATIENT(S) Ninety-four patients were divided into two groups. Group A consisted of 45 multiparous single fetus pregnant women with up to two previous cesarean sections (CS). Group B consisted of 49 multiparous pregnant women with up to three...

(Received: May 18, 2012; Accepted in Revised Form: February 4, 2013) Abstract: Direct oxidation of benzene to phenol in liquid phase in the medium of methanol, acetone, acetic acid and acetonitrile as a solvent over chromium catalyst supported on highly ordered nanoporous silica (Cr-LUS-1) by H O were examined. The best results obtained from methanol solvent with 20% yield and selectivity of 90...

Th e article in this issue of CHEST (see page 1586) by Bataille et al 1 on thoracic and lung ultrasonography (LUS) is of high interest. Th is study has the great merit of going in the right direction. To date, scientists explored the potential of LUS alone because it represents a new paradigm. Now, it is time to move on and explore how LUS may further improve diagnostic workup by combining it w...

Lung ultrasonography (LUS) is being increasingly utilized in emergency and critical settings. We performed a systematic review of the current literature to compare the accuracy of LUS and chest radiography (CR) for the diagnosis of adult community-acquired pneumonia (CAP). We searched in Pub Med, EMBASE dealing with both LUS and CR for diagnosis of adult CAP, and conducted a meta-analysis to ev...

BACKGROUND Sonographic examination of the lower uterine segment (LUS) has been used to diagnose a uterine defect and to determine the degree of LUS thinning in women with previous Caesarean section. Previous studies have demonstrated that the LUS thickness measured sonographically has a high negative predictive value for uterine rupture, suggesting that a normal LUS thickness predicts a safe tr...

Endometrial cancer arises from the uterine body and fundus in many cases, but can also originate from the lower region of the uterine body through the upper region of the cervix. Such tumors are referred to as carcinoma of the lower uterine segment (LUS) or isthmus, and account for 3-6.3% of all cases of endometrial cancer. This relatively low incidence has permitted performance of only small-s...

PURPOSE Ultrasonic lithotriptors are commonly used to fragment and remove stones during percutaneous nephrolithotomy. To date a comparative assessment of current units has not been accomplished without potential operator bias. An objective testing environment is required for optimal appraisal of the efficiency of ultrasonic lithotriptors. MATERIALS AND METHODS An in vitro test system was devi...

AIM To evaluate the diagnostic possibilities of lung ultrasonography (LUS) in detecting pulmonary complications in preterm infants with respiratory distress syndrome (RDS). MATERIAL AND METHODS A prospective study included 120 preterm infants with clinical and radiographic signs of RDS. LUS was performed using both a transthoracic and a transabdominal approach within the first 24 h of life, a...

Background: Lung ultrasound (LUS) used to identify interstitial syndrome (IS) and pleural thickening related to diffuse parenchymal lung disease (DPLD) has shown significant correlations with ground glass opacity (GGO) on high-resolution computed tomography (HRCT). However, the applicability of LUS in patients with DPLD subtypes as rare cystic lung diseases has not previously been investigated....
