Spiritoso R, Padley S, Singh S, 2015, Chest X-ray interpretation in UK intensive care units: A survey 2014., J Intensive Care Soc, Vol: 16, Pages: 339-344, ISSN: 1751-1437
PURPOSE: This survey investigated current practice in intensive care unit radiology reporting using a survey tool. We ascertained physician attitudes regarding best practice. METHODS: A national survey was sent by email to a sample of intensive care units throughout UK between March and October 2014. The questionnaire determined current practice in reporting chest X-ray in intensive care units. It also identified differences between 'routine' and emergency and out-of-hours service. Further, it investigated how reports were documented and physician preferences for perceived best practice. RESULTS: Of 146 intensive care units contacted, 55% completed the survey. Of the sample, radiologists were solely responsible for chest X-ray reporting in 43.7%, intensive care unit clinicians in 33.7% and joint reporting in 25% of intensive care units. The reporting clinician on intensive care unit was a consultant in 67% of the centres. Written reports by radiologists were provided in 71.7% of cases. This was only 54.5% when intensive care unit clinicians reported chest X-rays. For all routine and emergency films, written reports by radiologists occurred in 63.1% of responders. Out-of-hours, 54.9% of clinicians described different reporting practice to normal hours. Regarding perceived best practice, 64.8% of clinicians preferred joint daily reporting, whilst 27% preferred a radiologist's formal report. For emergencies, 55.2% of the survey recipients preferred a joint report. CONCLUSION: Based on this cohort of UK intensive care units, at present, there appears to be a lack of a standardised system for image reporting. There are discrepancies in who reports chest X-rays, written documentation and the timing of reports, more so out-of-hours. Clinicians suggest that joint reporting should be the standard.

Spiro SG, Hackshaw A, Shah P, et al., 2015, Research in progress-LungSEARCH: a randomised controlled trial of surveillance for the early detection of lung cancer in a high-risk group, Thorax, Vol: 71, Pages: 91-93, ISSN: 0040-6376
Low-dose CT screening for lung cancer is effective but expensive. Therefore, cheaper or more focused screening strategies may be required. LungSEARCH is a randomised prospective trial of 1568 high-risk individuals (ie, current or former moderate to heavy smokers with mild/moderate COPD) who undergo either annual sputum cytology/cytometry testing or no screening. Those with abnormal sputum then receive annual CT and fluorescent bronchoscopy for the remainder of 5 years, to identify early stage lung cancer. It is hoped that these simple initial tests could identify those requiring expensive CT scans, and the aim is to demonstrate a stage shift towards early stage cancers.
Patel HC, Otero S, Moser JB, et al., 2015, A cross-sectional imaging study to identify organs at risk of thermal injury during renal artery sympathetic denervation, International Journal of Cardiology, Vol: 197, Pages: 235-240, ISSN: 1874-1754
BackgroundThe technology used to perform catheter-based renal artery sympathetic denervation has evolved: catheters can now access arteries as small as 3 mm in diameter and create ablation zones of up to 10 mm in depth. Recent evidence suggests that the procedure may be more effective if a more thorough ablation strategy is employed. Limited data are available regarding inadvertent soft tissue thermal injury during such procedures. We used computed tomography (CT) to identify structures lying within the expected thermal ablation field or the ‘at risk zone’ (ARZ).Methods63 consecutive CT aortograms were reviewed, yielding 100 renal arteries anatomically eligible for treatment. Structures lying within a predefined ARZ (within 10 mm of the renal artery wall) were recorded.ResultsThe 63 subjects had a mean age of 74.6 years, 48% were males and 88% had hypertension. The inferior vena cava and renal veins were in the ARZ in all cases. Psoas muscles and small bowel were within the ARZ in at least a fifth of the kidneys. Other structures found in the ARZ included the liver, pancreas, adrenal glands and diaphragm.ConclusionsThis study describes the variable anatomical relationship between renal arteries and important abdominal structures that may be exposed to thermal energy during modern denervation procedures. The consequence of delivering such thermal energy to these structures is unknown but clinicians should be alert to the presenting symptoms if these structures are damaged. CT may have a pre-procedure role in assessing this risk.Keywords Renal denervation; Safety; Anatomy; Ablation; Cross-sectional imaging

Pulmonary lacerations are an uncommon injury typically associated with high-impact trauma. Most cases occur as a result of high-speed road traffic collisions. Although chest wall and pleural injuries are commonly associated with sports-related thoracic trauma, pulmonary injuries are far less common. There are only a few reported cases of significant pulmonary trauma associated with sports injuries, the majority of which have described pulmonary contusions occurring as a result of thoracic injury sustained while playing high-impact contact sports such as American football. Pulmonary laceration occurring as result of soccer-related thoracic trauma has never previously been reported.
