Internally cooled bone drills with an open system, conduct coolant directly to the point of contact of cutting surface of the drill and the bone and lower the temperature at the drilling site. During bone drilling with internally cooled drills of open type, there is a possibility that coolant enters the intramedullary canal and has an adverse effect on intramedullary pressure. In this research, the intramedullary distribution of the coolant during and after drilling was analyzed. ⋯ Coolant does not disperse into the intramedullary canal outside of the borehole in given flow ranges (0,6-1,35 l/min) and drill rotational speed regimes (1300-5000 rpm). Open type internally cooled can safely be used for bone drilling.

On the 4th of August 2020 an ammonium nitrate explosion took place at the Port of Beirut in Lebanon. The aim of this study was to present the open eye injuries caused by the Beirut Port blast, and to describe their characteristics and visual outcomes at 6 months. ⋯ Open eye injuries secondary to explosions occur most frequently due to glass fragments. Most of the victims were indoors, near windows and less than 500m away of the explosion site at the time of the blast. The majority of victims have very low BCVA, a low OTS and a high ocular ZOI at presentation which reflects the danger of open globe injuries secondary to blasts. A high ZOI, a low OTS, the expulsive loss of intraocular tissue and retinal detachment seem to be predictors of worse VA at 6 months.

To evaluate and compare the accuracy of axial versus coronal computerized tomography (CT) scan in detection of open globe injury. ⋯ Axial CT reading may be as adequate as a multiplanar reading in detection of open globe injury in emergency setting, where timely diagnosis matters. Without clinical and surgical findings, CT cannot provide adequate accuracy for detecting open globe injuries.

The aim of this manuscript is to compare characteristics, management, and outcomes of patients with severe Traumatic Brain Injury (TBI) between Australia, the United Kingdom (UK) and Europe. ⋯ There are major differences in case-mix between Australia, UK, and Europe; Australian patients are younger and have a higher rate of secondary brain insults. Despite some differences in management and discharge policies, mortality was less than expected overall, and did not differ between regions. Functional outcomes were similar between regions, but worse than expected, emphasizing the need to improve treatment for patients with severe TBI.

Most blunt renal injuries (BRIs) are managed conservatively without complications. Because conservative management with observation (CMO) is widely conducted, failed CMO is frequent. Clarifying the role and indication of CMO is important to manage BRI patients. Therefore, this study was conducted to analyse factors related to failed CMO. ⋯ PHD and ICE may be useful factors to predict failed CMO for BRI patients. PHD > 2.9 cm and the presence of ICE may indicate who will require invasive procedures. Close observation is wise for patients with these risk factors.
