Echocardiography and imaging investigation in congenital cardiovascular anomalies - competition or complementarity? Part II: cyanogenic cardiovascular malformations. Pictorial essay.
The diagnosis of cardiovascular malformations (CVM) is based on the echocardiographic evaluation. Multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) are performant, necessary techniques for the pre- and postoperative assessment of complex malformations, especially of cyanogenic malformations, in which anomalies of the right side of the heart and of the pulmonary circulation are involved and where echocardiography has a limited role. The complementarity of echocardiography with MDCT and MRI for the acquisition of the details necessary for an accurate therapeutic decision and for avoiding invasive exploration, as well as the close relationship between the radiologist and the clinician are crucial and all the more necessary in complex malformations.

Case ReportsPseudoaneurysma of the external jugular vein communicating with the internal jugular vein. Case report.
True and false aneurysmas (pseudoaneurysmas) of veins are very rare conditions. We present the case of a 58 year old woman with a progressive spheric enlargement with pusatile character of the right laterocervical area. ⋯ The particularities of this case are the absence of an obvious etiology and the particular variant of flow direction from internal towards the external jugular vein. To the best of our knowledge, this is the first case of pseudoaneurysma of the external jugular vein reported in literature.

A complete physical examination of the hip is often difficult due to its size and deep position. During the last two decades, ultrasonography (US) of the hip has been widely accepted as a useful diagnostic tool in patients with hip pain and /or limited range of motion. It is commonly used in both adults and children. ⋯ The relatively limited acoustic windows available to the US beam are the principal limitations to hip US. Therefore, conducting a detailed examination of some important structures together with the interpretation of Doppler signal (sometimes undetectable) is not easy, requiring good knowledge of the modality. The aim of this review is to analyze the current literature about US of the hip and to describe the most frequently-observed normal and pathological findings.

Ultrasound-guided injections in the middle and lower cervical spine.
Injection therapies play a major role in the treatment of cervical pain and are becoming integral parts of a multidisciplinary approach in treatment and rehabilitation of such patients. Pararadicular- and facet-joint injections in the cervical spine are preferentially performed under computed tomography (CT) or fluoroscopy-guidance. In this article we present an alternative, simple and easy to learn step by step US-guided technique for injection therapy in the cervical spine.

Teaching basic shoulder ultrasonography to orthopaedic postgraduate trainees--effectiveness of a training workshop.
Ultrasound examination of the shoulder conducted by orthopaedic surgeons in the diagnosis and treatment of shoulder conditions is increasingly reported. Shoulder ultrasound is not a mandatory component of postgraduate orthopaedic training in the United Kingdom. The aim of this study was to assess the effectiveness of the shoulder ultrasound teaching workshop administered to postgraduate orthopaedic surgical trainees. ⋯ Our study shows that a basic shoulder ultrasound teaching workshop can be effective in equipping postgraduate orthopaedic trainees with basic ultrasound techniques. It could potentially become part of a structured orthopaedic training programme.
