False appendicitis alarm

Study reveals many unnecessary appendix surgeries in children

Surgery for appendicitis is the most common emergency operation in children. A new study has found that the UK has the highest reported national rate of ‘normal appendicectomy,’ where children undergo surgery for suspected appendicitis but laboratory examination of the removed appendix finds it to be normal. Although most children who are misdiagnosed as having appendicitis improve without…

Ultrasound selectively damages cancer cells (with the right settings)

Doctors have used focused ultrasound to destroy tumors in the body without invasive surgery for some time. However, the therapeutic ultrasound used in clinics today indiscriminately damages cancer and healthy cells alike. Most forms of ultrasound-based therapies either use high-intensity beams to heat and destroy cells or special contrast agents that are injected prior to ultrasound, which can…

Ultrasound in intracranial injuries

A future gold standard tool

Whilst researchers acknowledge ultrasound, when used as a tool to assess intracranial pressure in an emergency, is not a replacement for current gold standard invasive approaches, they believe it has enormous potential as a non-invasive and fast, cost-effective, and patient-friendly way to assess possible brain injury at a patient’s bedside. Consultant anaesthetist Dr Chiara Robba, a specialist…

Minimally invasive

Improved biopsies with MRI-compatible ultrasound system

Biopsies are standard procedures in interventional radiology, not least for patients with a suspected tumor. In this instance, MRI is increasingly the method of choice for guiding minimally invasive tissue sampling. Yet this involves having to undergo repeated MRI scans, which patients find uncomfortable. In an ongoing R&D project, Fraunhofer researchers have now developed a system that…

UK tests high-speed remote medical diagnosis

Ultrasound scanning via a 5G network

To demonstrate advances in 5G connectivity for healthcare, a UK team has linked a paramedic in a simulated ambulance to a hospital-based clinician. The paramedic wore a robotic or ‘haptic’ glove, which received signals over the live 5G network. Using a joystick, the clinician remotely directed the paramedic to move the ultrasound sensor to where on the patient the clinician wanted to scan.…

One for all – standardising medical equipment

Point-of-care ultrasound (POCUS) is widely used in hospitals across the country. However, as these systems are often shared between departments, and consultants may work at more than one hospital within a trust, there is a clear advantage to choosing instruments from a single supplier wherever possible. Jim McWilliams, Associate Director for Technical Services at Hinchingbrooke Hospital in…
