Transcutaneous ultrasound enables visualization of pleural based lesions but with a poor correlation to specific pathology. Ultrasound contrast agents in conjunction with contrast specific imaging techniques are increasingly accepted in clinical use. Up to date there are no data about the use of contrast enhanced sonography (CES) in a large series of pleural based pulmonary lesions. ⋯ Pulmonary lesions are characterized by different CES-patterns of arterial supply as evidenced by TE and EE which depends on underlying causes, but CES does not allow to distinguish benign from malignant pleural based lesions in general.

The aim of our study was to examine gastric function, gallbladder emptying, and dyspepsia in symptomatic gallbladder stone patients (SGBS) to see if a motility disorder, expressed by gastric function and gallbladder emptying, may cause dyspepsia in SBGS. ⋯ SGBS had a wider proximal stomach and more hunger in the fasting state than C. After cholecystectomy the proximal stomach function and the hunger score improved. Our results suggest a physiological link between symptomatic gallstone disease and dyspepsia expressed by impaired proximal gastric function.

Interscalene plexus blocks are an important part of the peri-operative treatment in shoulder surgery. The nerve stimulation technique uses external landmarks for the definition of the injection site. Patient obesity is, therefore, one causative factor for a reduced success rate of the blockade. ⋯ Portable ultrasound provides efficient depiction of the interscalene plexus structures in obese patients and, when used for guidance of regional blockade, renders similar results as in patients of normal weight.

We studied the anatomy of the sciatic nerve and its division into the tibial and peroneal part using handheld ultrasound in adults. We wanted to evaluate the feasibility of ultrasound-guided identification of the sciatic nerve in the popliteal fossa and the correlation of the findings by ultrasound with patients' characteristics. ⋯ We could depict the sciatic nerve in all volunteers and its division in 53 of 74 (72%) volunteers. The position of nerve division showed large anatomic variation. A significant correlation between the width of the knee-joint line and the depth of the nerve division could be demonstrated. We conclude that handheld ultrasound is able to depict the sciatic nerves division. To block the nerve by one injection a more proximal access or visualization by mobile ultrasound is recommended. In addition the surrounding anatomic structures can be depicted as well.
