RESUMO
BACKGROUND: Patients with lung cancer exhibit increased risk of pulmonary embolism (PE). While the contrast phase of computed tomography of the chest in the diagnostic work-up of suspected chest malignancy does not allow reliable detection of PE, it may be feasible to screen for present PE during endobronchial ultrasound (EBUS) examination. OBJECTIVES: The aim of this study was to establish if screening during EBUS for PE in patients with suspected lung cancer is feasible and if positive findings are predictive of PE. METHODS: Patients undergoing EBUS due to suspicion of malignancy of the chest were prospectively enrolled. The pulmonary arteries were assessed during EBUS using a standardized protocol. Patients in whom PE suspicion was raised were referred to confirmatory imaging. RESULTS: From December 2020 to August 2021, 100 patients were included. Median time for vascular assessment during EBUS was 2 min (Q1-Q3: 1-3 min). EBUS identified two suspected PEs (2%), and the number needed to scan was 50. The positive predictive value of EBUS for PE was 100%. CONCLUSION: EBUS for PE screening seems feasible and with limited time use. The PPV of positive findings for the diagnosis of PE is high, but the utility is somewhat limited by a high number needed to scan even in a high-risk population. Based on our findings, we believe that EBUS assessment of the pulmonary vasculature may have a role as a routine screening tool for PE. The assessment for PE should be implemented in EBUS training programmes, as operators should be able to recognize incidental PEs.

INTRODUCTION: The aim of this study was to examine the development in incidence rates and the severity of weapon-related physical interpersonal violence in Odense Municipality, Denmark from 1991 to 2009. METHODS: All victims of physical interpersonal violence with weapon-related injuries treated at the Emergency Department in the 1991-2009 period at Odense University Hospital, Denmark, and/or subjected to medico-legal autopsy at the Institute of Forensic Medicine in the 1991-2009 period at the University of Southern Denmark were included. Incidence rates were estimated following stratification by gender and age. The development in the incident rates was examined. RESULTS: Overall, 2,957 victims were included. The overall incidence rate was 8.5 per 10,000 population/year (14.6 and 2.7 for males and females, respectively). The rates did not change significantly in the study period. Most victims were injured with bottles/glass and blunt weapons (44.8% versus 28.2%), whereas 24% were injured with sharp weapons and 3% with firearms. Most lesions were sustained to the head/neck (56.1%) and to the upper limbs (26.2%). A total of 182 (6.1%) victims had lesions that were considered severe. The mortality rate was 4.8 per 1,000 victims in males and 29.1 per 1,000 victims in females. More than half (57%) of the homicides were caused by lesions due to sharp weapons. CONCLUSION: Weapon-related injuries are rare in the Odense Municipality. The incidence rate of weapon-related violence did not increase in the study period. Additionally, no evidence of an increased proportion of severe injuries was found. Women had a seven-fold higher mortality than males. FUNDING: none. TRIAL REGISTRATION: not relevant.
