Quick radiological diagnosis is often needed in order to allow the clinicians to make a diagnosis. The purpose of this study was to measure examination time for radiology procedures before and after physical integration of a radiology unit in the ED. We retrospectively acquired data from the radiology information system and compared time from referral to end of radiological examination before and after physical integration of the radiology unit in the ED for 19,897 X-ray and 6,940 CT examinations. After integration examination time for X-ray examinations was reduced by 5 to 14 minutes (p<0.001). For CT head and chest examination time was reduced by 7 to 15 minutes (p<0.003) while examination time for CT abdomen was prolonged by 4 minutes (p=0.78).

Acute Haemorrhage

Objectives: The aim of this paper is to assess the acute haemorrhage rate in patients who had CT head investigation out-of-hours with and without trauma and compare the rates of haemorrhage between warfarin and DOACs, at a busy teritary teaching hospital. Methods: All CT heads performed between January 2008 and December 2019 were identified from the radiology information system (RIS) at Sheffield Teaching Hospitals (STH), with the requesting information being available from January 2015. The clinical information was assessed for the mention of trauma or anticoagulation and the reports were categorised into acute and non-acute findings. Results: Between 2008 and 2019 the number of scans increased by 63%, with scans performed out of hours increasing by 278%. Between 2015 and 2019, the incidence of acute ICH was similar over the 5 year period, averaging at 6.9% and ranging from 6.1 to 7.6%. The rate of detection of acute haemorrhage following trauma was greater in those not anticoagulated (6.8%), compared with patients on anticoagulants such as warfarin (5.2%) or DOACs (2.8%). Conclusions: Over 12 years, there has been a significant increase in the number of CT heads performed at STH. The rate of ICH has remained steady over the last 5 years indicating a justified increase in imaging demand. However the incidence of ICH in patients prescribed DOACs is lower than the general population and those on warfarin. Advances in knowledge: : This finding in a large centre should prompt discussion of the risk of bleeding with DOACs in relation to CT head imaging guidelines.

The Impact

Object Recent legislation and media coverage have heightened awareness of concussion in youth sports. Previous work by the authors' group defined significant variation of care in management of children with concussion. To address this variation, a multidisciplinary concussion program was established based on a uniform management protocol, with emphasis on community outreach via traditional media sources and the Internet. This retrospective study evaluates the impact of standardization of concussion care and resource utilization before and after standardization in a large regional pediatric hospital center. Methods This retrospective study included all patients younger than 18 years of age evaluated for sports-related concussion between January 1, 2007, and December 31, 2011. Emergency department, sports medicine, and neurosurgery records were reviewed. Data collected included demographics, injury details, clinical course, Sports Concussion Assessment Tool-2 (SCAT2) scores, imaging, discharge instructions, and referral for specialty care. The cohort was analyzed comparing patients evaluated before and after standardization of care. Results Five hundred eighty-nine patients were identified, including 270 before standardization (2007–2011) and 319 after standardization (2011–2012). Statistically significant differences (p < 0.0001) were observed between the 2 groups for multiple variables: there were more girls, more first-time concussions, fewer initial presentations to the emergency department, more consistent administration of the SCAT2, and more consistent supervision of return to play and return to think after adoption of the protocol. Conclusions A combination of increased public awareness and legislation has led to a 5-fold increase in the number of youth athletes presenting for concussion evaluation at the authors' center. Establishment of a multidisciplinary clinic with a standardized protocol resulted in significantly decreased institutional resource utilization and more consistent concussion care for this growing patient population.

Soft tissue abnormalities on radiological examination can be useful in evaluating injury to various regions. In a retrospective study of X-ray pictures of 125 patients with injury to the wrist, it was possible to demonstrate an abnormal scaphoid fat stripe (SFS) in seventy-three out of seventy-eight cases with fracture of the scaphoid bone, compared to ten out of forty-seven cases without fracture.

Background: Asthma is a heterogeneous disease characterized by cough, wheeze and shortness of breath that vary in intensity and time with variable expiratory airflow limitation, associated with chronic airway inflammation. Aim of the study was to assess the usefulness of Peak Expiratory Flow Rate [PEFR] and oxygen saturation in determining severity of acute asthma, to measure objective change in PEFR and oxygen saturation following bronchodilator therapy and the role of chest X-rays in acute asthma.Methods: A prospective study of 50 children above 5 years with acute asthma who presented to the emergency department in a tertiary care hospital were included. PEFR and oxygen saturation before and after bronchodilator therapy was measured. Indication for chest X-rays, its clinical correlation and change in standard treatment of acute asthma based on X-ray reports was noted.Results: The mean PEFR and PEFR % of expected was lower in severe asthma when compared to moderate asthma and was statistically significant (p<0.001). The % of expected PEFR before salbutamol therapy was 48.78±14.36, which improved significantly to 67.13±14.22 after treatment (p<0.001). Oxygen saturation before and after salbutamol therapy was 94.96 ± 4.11 and 96.96±2.87 respectively with the change being significant (p value <0.001). Chest X-rays were performed in 12 (24%) children as per standard guidelines, of which 1(9%) was abnormal showing right basal consolidation. Chest X-ray correlated with clinical findings in 1 child and the findings on chest X-ray altered the ongoing treatment by addition of antibiotic.Conclusions: PEFR and oxygen saturation is useful in the emergency department to objectively assess the severity of acute asthma and the response to initial bronchodilator therapy. Chest X-rays are not routinely indicated in the standard treatment of acute asthma.

Set Up

Freeze-etching electron microscopy is currently one of the best methods for studying molecular organization of biological materials. Its application, however, is still limited by our imprecise knowledge about the perturbations of the original organization which may occur during quenching and fracturing of the samples and during the replication of fractured surfaces. Although it is well known that the preservation of the molecular organization of biological materials is critically dependent on the rate of freezing of the samples, little information is presently available concerning the nature and the extent of freezing-rate dependent perturbations of the original organizations. In order to obtain this information, we have developed a method based on the comparison of x-ray diffraction patterns of samples before and after freezing, prior to fracturing and replication.Our experimental set-up is shown in Fig. 1. The sample to be quenched is placed on its holder which is then mounted on a small metal holder (O) fixed on a glass capillary (p), whose position is controlled by a micromanipulator.

Aluminum-copper-silicon thin films have been considered as an interconnection metallurgy for integrated circuit applications. Various schemes have been proposed to incorporate small percent-ages of silicon into films that typically contain two to five percent copper. We undertook a study of the total effect of silicon on the aluminum copper film as revealed by transmission electron microscopy, scanning electron microscopy, x-ray diffraction and ion microprobe techniques as a function of the various deposition methods.X-ray investigations noted a change in solid solution concentration as a function of Si content before and after heat-treatment. The amount of solid solution in the Al increased with heat-treatment for films with ≥2% silicon and decreased for films <2% silicon.
