Handheld Ultrasound devices (HHUSD): A short review of the equipment available on the market as of September 2017 Michael Bachmann Nielsen Department of Radiology, Rigshospitalet, DK 1302 Copenhagen, Denmark mbn@dadlnet.dk The handheld ultrasound devices (HHUSD) equipment included in this short paper are devices with a screen size of a mobile phone or a small tablet up to 7 inches. This it to separate the devices from those sold as portable. One of the many advantages by HHUSD is that they can be easily carried for use in any clinical situation they may be needed. The websites of more than 25 ultrasound manufacturers were searched by the author in September 2017 and while almost everyone listed portable devices only six were found to have HHUSD by the definition above. They are listed below in random order.

GE Healthcare’s Vscan series has been available for several years and now covers several pocket-sized models with a screen and a (cabled) transducer. Dual probes are available with options for Doppler and DICOM connectivity. Philips Lumify was launched in the US in 2015 and from 2017 it is also available in Europe, in some countries on a subscription basis. The transducer connects via USB to your own phone or tablet (only android). Several transducers are available. The system includes Doppler and DICOM connectivity. Clarius has two probes available, each with wireless connection to your own smart device using an app. The system includes Doppler and DICOM connectivity. Mobisante has two systems, one that comes with a screen and one where the probe can be plugged into your own device. DICOM is supported.

Signostics works with android devices only, one selling point is accurate bladder volume measurements and point-of-care ultrasound (POCUS). The iViz from Sonosite has a 7.1" display with a one-handed interface and two cables transducers are available. Doppler and export to DICOM is available. This overview is based on a presentation I updated for the EUROSON Congress in September 2017. I looked at international websites of selected ultrasound manufacturers, I apologize if I have overlooked some. Those without HHUSD on their website may well be about to launch such a device so it is always a good idea to attend the technical/ commercial exhibition in larger congresses for the latest developments on the market. Please also note that the author is not associated with any of the companies listed above and does not own any of these devices. Therefore, this short report is not about my preferences, only a quick survey of the available market as of September 2017. Currently EFSUMB is finalizing a position paper on HHUSD focused on the published literature on their use. For most of the devices the manufacturers highlight POCUS as their intended use.

Dermatological Ultrasound in EFSUMB: An application that has come to stay, grow and last The ultrasonographic study of skin and appendages (hair and skin) is a growing recent development in clinical dermatology and aesthetic medicine. New equipment with lineal high frequency probes and highly sensitive Doppler have been key techinical developments that have permitted the use of ultrasound for the study of the heatlhy and pathological skin. Since pioneer seminal work of Dr Wortsman in Chile, dermatological ultrasound has

Ultraschall in Med 2017; 38: 668–674

evolved and been introduced in clinical practice by the dermatologic community, mainly in European countries. Recently the DERMUS group, an independent group that includes dermatologists and radiologists globally have published

practice guidelines for this aplication in the AIUM Journal and have set a standard for the practice and teaching of dermatologic ultrasound for the radiologists and clinicians interested in this application.

From EFSUMB we have created a working group for the development of this application in Europe with the idea of bringing together expertise, investigation and learning to the interested physicians. With that intention and aiming to create an European consensus on the practice of dermatological ultrasound in Europe under the EFSUMB umbrella, the First Dermatological Ultrasound Euroson School (Level 1) is being

organised in which formal theoretical and practical state of the art of this application will be taught by leading experts in this speciality. Along with the course a formal acreditation on dermatological ultrasound level one by EFSUMB will be offered to participants who succeed in the theoretical and practical evaluation of this course.

This event will take place in the Dermatological Ultrasound Teaching Centre Puerta de Hierro Majadahonda, Madrid, Spain next 1st and 2nd June 2018. For those interested in this new and rapidliy evolving technique this is a great oportunity to learn in depth the fundamentals of the application in the clinical environment. We hope to see you in Madrid next June. Dr. Fernando Alfageme

Abstract Submission: 2.01.2018 – 15.06.2018 First announcement: December 2017

The role of infection control within the ultrasound unit Ultrasound technology has rapidly evolved over the past decade with increased use to aid in the diagnosis of a variety of medical conditions. With the ease of smaller portable machines and frequent use, comes the risk of improper hygiene and lack of disinfection of equipment post patient use. The prevalence of healthcare associated infections ranges from 1.7 million in the US (Klevens et al., 2007) to 200 000 in Australia (Cruickshank and Ferguson, 2008) and antimicrobial resistance is now considered a global threat. The infectious status of a patient is not often disclosed to the ultrasound user and this poses a risk for the transmission of infection from patient to ultrasound user or to the next patient if the ultrasound equipment has not been cleaned between use. Many ultrasound training programs focus on the technological aspects of scanning

but do not cover training in basic infection, prevention and control. There have been reported cases of infection resulting from ultrasound guided procedures (Cervini et al., 2010; Ferhi et al., 2013; Hiyama et al., 2016) and a fatality due to Hepatitis B infection after failure to decontaminate a transoesophageal transducer (Medical safety alert: No. MDA/2012/ 038). Keys et al (2015) highlighted that over 60 % of ultrasound transducers were covered in blood and bodily fluids in the Emergency department. This statistic is not surprising given the ‘unclean’ ultrasound transducers that are found within departments with visible dried blood (▶ Fig. 1). Other studies have shown that the entire ultrasound unit can be contaminated by various microorganisms, both commensals and potential patho-

gens (Alfa et al., 2015; Westerway et al., 2016). Apart from ultrasound equipment, the gel poses a potential risk of transmission of infection. Ultrasound gel is conducive to microbial growth, especially when reheated and the lid left open allowing entry of microorganisms. Infections associated with contaminated ultrasound gel have been reported (Cheng et al 2016; Chittick et al., 2013; Oleszkowicz et al., 2012, Abdelfattah et al., 2017) including an outbreak of Burkholderia cenocepacia infection following ultrasound guided central line placement attributed to sterile gel (Shaban et al., 2017). Furthermore, 2 patients died as a result of septic shock from contaminated ultrasound gel used in central line placement (Abdelfattah et al., 2017). This highlights the importance of government regulation, strict testing and efficient labelling of products. As such, the

Transducers” (Basseal et al., 2017). These comprehensive guidelines include flowcharts for best reprocessing practice and will form the framework for the WFUMB guidelines to be published shortly. It would be sensible for all users of ultrasound to undertake basic infection control training and study the published Guidelines to ensure optimal patient safety during an ultrasound examination. ▶ Fig. 1 Blood contaminated ultrasound transducers.

entire ultrasound unit including gel should be considered as a potential vector in the transmission of a healthcare associated infection. In an attempt to further comprehend the hygiene and disinfection practices within the ultrasound unit, a survey was launched by the World Federation for Ultrasound in Medicine and Biology (WFUMB) via its six Federations (Basseal and Westerway, 2017). Results from the United Kingdom indicated that ultrasound users were overwhelmed with high throughput of patients which potentially affected the ability to clean the ultrasound equipment (Westerway and Basseal, 2017a). Similar results were obtained from the Australasian region, which illustrated that non-approved agents were utilised for high level disinfection of ultrasound transducers and approximately half of the respondents do not receive any support from their infection control department (Westerway and Basseal, 2017b). These findings indicated a gap in knowledge of basic infection prevention and control education as well as a lack of support in the area. Many ultrasound organisations as well as national health agencies are responsible for producing best practice guidelines for optimal patient care. The Australasian Society for Ultrasound in Medicine (ASUM – the peak body for ultrasound in Australasia) in collaboration with the Australasian College of Infection Prevention and Control (ACIPC – the peak body for infection prevention and control in Australasia) released joint “Guidelines for Reprocessing Ultrasound
