Vascular Color-Coded Duplex Ultrasound in Practice: Artifacts.

[Vascular Color-Coded Duplex Ultrasound in Practice: Artifacts]. Praxis (Bern 1994). 2019 Aug;108(10):679-684 Authors: Hügel U, Rosenov A, Baumgartner I, Thalhammer C Abstract Vascular Color-Coded Duplex Ultrasound in Practice: Artifacts Abstract. Ultrasound artifacts are technical phenomena which may cause diagnostic mistakes and do not correlate with the real target organ. These optical and acoustic phenomena of color-coded duplex ultrasound are very common in the real world and may lead to misinterpretations and diagnostic errors. The twinkling artifact, for example, imitates high-flow velocities and turbulences, which may lead to the misdiagnosis of a high-grade stenosis or of vascularization. Mirror image artifacts may irritate the sonographer and cause an impression of an additional - really not existing - vessel. The "seagull cry", whose origin is not well understood, is usually found in the region of a high-grade stenosis. PMID: 31387491 [PubMed - in process]

ConclusionResection is the most suitable therapy for clinical symptoms of a foreign body in the upper aerodigestive tract and inflammatory complications; total thyroidectomy follows in case of malignant transformation. Thyroid heterotopy is a rare pathological condition, yet it should be taken into consideration during differential diagnosis of tumorous oropharyngeal and neck lesions.

Authors: Yoshida M, Naitoh I, Hayashi K, Jinno N, Natsume M, Hori Y, Kato A, Kachi K, Asano G, Matsuo Y, Takahashi S, Kataoka H Abstract Pancreatic serous cystic neoplasms (SCNs), such as serous cystadenoma (SCA), are generally recognized as benign because malignant counterparts of SCNs have been extremely rare. In clinical practice, pancreatic cystic neoplasms diagnosed as SCNs have been managed by conservative observation, as long as the patients remained asymptomatic. We herein report a case of metachronous ductal adenocarcinoma that was discovered during long-term follow-up of SCN and review the related literat...

Conclusion: MFU-V is a well-known and, based on the evidence, an effective tool for non-invasive lifting and skin tightening. The secret to successful use of the device is to assess adequately patient needs and expectations and plan ahead for the combination of other treatment if necessary to achieve the desired outcome.

Authors: Schilling EM, Weinrich M, Heller T, Koball S, Neumann A Abstract Our patient exhibited a large tumor on his right upper arm where his former dialysis access site had been. X-ray, Doppler ultrasound, and magnetic resonance imaging scan could not fully reveal the nature of that tumor. Eventually, a surgical approach showed a giant aneurysm of the inflowing brachial artery to a partially obliterated arteriovenous fistula. This case highlights the importance of ongoing care for patients with arteriovenous shunts. Even arteriovenous fistulas, that are obliterated or no longer in use, can, especially when immuno...

The objective of this work was to introduce high-intensity ultrasound (HIU) in different positions within a scraped surface heat exchanger (SSHE) and evaluate the crystallization behavior and physical properties of a low saturated, soybean-based fat. The SSHE in this study was composed of one pump (flow rate of 11 L/h), two crystallization barrels (32 °C, 344 rpm), and one pin worker (208 rpm). HIU was placed before the first crystallization step, or barrel 1 (HIU-0), between the two barrels (HIU-1), between barrels 2 and the pin worker (HIU-2) and after complete crystallization in the SSHE (HIU-3). HIU amplitu...
