Multicenter StudyMusculoskeletal ultrasound guided manoeuvres - a security profile.
In daily rheumatology clinical practice, routine interventional musculoskeletal ultrasound (MSUS) guided maneuvers such as aspiration, intraarticular or periarticular drug injections require efficient cleaning and disinfection methods for both transducer and patient's skin. ⋯ Rigorous transducer dry cleaning and Bethadine / Bethadine and alcohol 70° skin disinfection are efficacious methods. The risk for septic complications and other drug related side effects related to MSUS guided injections is very low in this context. A correct injection technique must accompany the previous requests. Rapid and safe interventional maneuvers reduce the risks and control the costs of the healthcare system.

The axillary brachial plexus block is the most widely performed upper limb block. It is relatively simple to perform and one of the safest approaches to brachial plexus block. With the advent of ultrasound technology, there is a marked improvement in the success rate of the axillary block. This review will focus on the technique of ultrasound guided axillary brachial plexus block.

ReviewHow can the use of lung ultrasound in cardiac arrest make ultrasound a holistic discipline. The example of the SESAME-protocol.
The most critical application of critical ultrasound - cardiac arrest - is the opportunity for technical considerations. The necessity to immediately detect reversible causes is integrated in the concept of holistic ultrasound. Holistic ultrasound is defined as a discipline where each element interacts with the others, and where the understanding of each of them allows understanding the whole. ⋯ The concept of holistic ultrasound is particularly on focus in the first step done at the lung (search for pneumothorax and clearance for fluid therapy), since the best image is obtained with the simplest equipment devoid of traditional facilities (image filtering, harmonics, time lag, Doppler...). The same simple gray-scale equipment is used for the other steps, all what is needed is to see the real-time image of what is facing the probe: the very principle of visual medicine. The same approach can be used with no change, just more quietly, for many less urgent settings.

Case ReportsThe thoracic spine sign in bedside ultrasound. Three cases report.
The "thoracic spine sign" is visualized when anechoic or hypoechoic fluid is present in the pleural space. Fluid serves as a medium through which the thoracic vertebral bodies are visualized above the diaphragm. ⋯ These patients were subsequently diagnosed with pleural fluid accumulations on chest radiograph. Our findings suggest that the identification of the sonographic spine sign may aid the physician in the evaluation and diagnosis of emergency department patients with thoracic complaints.

Review Comparative StudySurgical hepatic resection vs. ultrasonographic guided radiofrequency ablation in colorectal liver metastases: what should we choose?
Clinical evolution of the colorectal carcinoma occurs in up to 60% with colorectal liver metastases (CRLM). Although hepatic resection is considered to be the golden standard in CRLM, novel less invasive techniques have emerged, of which radiofrequency ablation has received a high credibility. ⋯ While open surgery guarantees a more precise tumor excision, the effectiveness of ablation must be evaluated either by contrast-enhanced computer tomography, magnetic resonance, or ultrasound. This paper aim to review the current standings in radiofrequency ablation for CRLM and to compare the technique with surgical resection in order to find which one is the best treatment option.
