Portable X-ray scanner
Medical staff are real heroes when they have to provide the necessary assistance to survivors, in disaster areas. The Xavier Portable X-Ray by Danwei Ye was designed to enable medical teams to perform even better care in harsh conditions. It is no secret that their performance is often affected by the limited access to useful devices, in problematic zones. X-ray machines are the perfect illustration of that. They are indeed so heavy that transporting them turns out to be a real ordeal. Add to this the fact that even the smallest ones require an expert to operate them…
The Xavier Portable X-Ray is unique in its kind: it is both compact and easy to transport. Laminographic scanning will enable any user to identify the location of a broken bone. No worries about facing a power outage disruption: a built-in rechargeable battery as well as a power generator are included to the genius system. These units can be activated to generate extra power, simply by pulling the handle they are connected to. The X-Ray device folds into a small rubber case for simplified transportation. Perfectly portable, unfoldable in seconds and convenient to operate. Heroes now have powerful tools to assist them in their mission!
Using the “low-risk ankle rule” to assess children’s ankle injuries in emergency departments significantly reduces X-ray imaging, according to aCanadian Medical Association Journal study.
Nearly 2200 patients aged 3 to 16 years presented with acute ankle injuries to emergency departments designated as either intervention or control sites. Intervention sites applied the rule, which says that radiography may not be necessary when tenderness and swelling is isolated to the distal fibula and the adjacent lateral ligaments distal to the tibial anterior joint line. At control sites, procedures for ankle injuries were unchanged.
After implementation of the rule, intervention sites saw a 22-percentage-point reduction in weekly ankle radiography, compared with controls. Application of the ankle rule was not associated with an increase in significant fractures being missed or a decrease in physician or patient satisfaction.
The authors conclude: “Widespread implementation of this rule could safely lead to reduction of unnecessary radiography in this radiosensitive population and a more efficient use of healthcare resources.”
A 79-year-old man presented with symptoms and signs of upper respiratory tract infection; he had a history of permanent pacemaker implantation. An upright postero-anterior chest radiograph showed a raised right hemidiaphragm delineated by subdiaphragmatic air. Unlike free air, which forms an uninterrupted crescent-shaped subdiaphragmatic radiolucency, this radiograph showed a haustral pattern of subdiaphragmatic lucency, overlapping the upper border of the liver shadow. On examination, clinical findings suggesting acute abdomen from rupture of a hollow viscus were absent and there was no recent history of abdominal surgery to account for the presence of subdiaphragmatic air.
The visualisation of a gas filled transverse colon lumen interpositioned between the right hemidiaphragm and the liver on a chest film is called Chilaiditi’s sign. A CT scan may confirm these anatomical relations. In our patient’s radiograph, the haustral pattern of air was indicative of colonic origin, and the continuity of the subdiaphragmatic air was broken up by the shadow of the vertical plicae semilunares of the colon. Chilaiditi’s sign was first described in 1910 by Demetrious Chilaiditi and it is an incidental radiographic finding. This sign can be mistaken for pneumoperitoneum and can lead to needless surgical intervention. Our patient was treated only for his upper respiratory tract infection.
