RESUMO
PURPOSE: This retrospective cohort study explores the impact of the COVID-19 pandemic on pediatric trauma cases in Singapore's National University Hospital from January 2015 to July 2021. The pandemic prompted unprecedented measures, altering societal dynamics. The study hypothesizes a reduction in major trauma incidents during the pandemic period. METHODS: This is a single-center retrospective study including all pediatric patients presenting with trauma-related ICD-9 codes, and an Injury Severity Score (ISS) greater than 8. Patients were stratified into two time periods: pre-pandemic (January 2015 to March 2020) and pandemic (April 2020 to July 2021) periods. RESULTS: Out of 254 pediatric trauma cases, 201 occurred pre-pandemic, and 53 during the pandemic. While overall trauma incidence remained similar, the pandemic period saw a shift in injury patterns. Home-based falls increased, vehicular accidents decreased, while deliberate self-harm and caregiver abuse rose significantly. The incidence of serious trauma attributed to non-accidental injury increased during the pandemic. CONCLUSION: The study reveals changing trauma patterns, emphasizing the importance of understanding societal impacts during pandemics. Notably cases of deliberate self-harm and caregiver abuse surged, echoing global concerns highlighted in other studies during the pandemic. The study underscores the need to preempt physical and psychological stressors in vulnerable populations during future pandemics.

INTRODUCTION: This study aimed to assess understanding of the potential risks associated with medical imaging among caregivers and adolescent patients in a paediatric emergency department (PED) in Singapore. METHODS: A prospective convenience sample survey was performed involving adolescents and caregivers presenting to our PED from December 2015 to May 2016. The questionnaire examined demographic data, knowledge of imaging procedures and radiation risks, and expectations regarding information provided about medical radiation. RESULTS: A total of 349 questionnaires were returned (caregivers 82.5%, adolescents 17.5%). A mean of 6.2 ± 2.4 (out of 11) questions were correctly answered. Those who had tertiary education fared better than those who did not (36.4% vs. 17.2% scoring above the mean, p = 0.001). Age, gender, history of previous imaging and imaging performed during the visit did not affect the score. Two-thirds of the participants did not associate medical radiation with any negative lifetime risk of cancers or know that different scans entailed differing amounts of radiation. Most were unaware that the radiation dose in medical imaging is adjusted to a child's size. Among patients who underwent imaging, 90.1% received explanations on the need for scans, and 26.5% were informed of the risks involved. Almost all participants wished to be informed of imaging indications and risks. More preferred to learn this from physicians (75.6%) or technicians (51.6%) rather than through educational pamphlets (34.4%) or Internet resources (22.9%). CONCLUSION: Awareness regarding medical radiation needs to be improved in our patient population. A mismatch exists between caregiver expectations and the actual procedure of disclosure of the risk associated with radiation.

AIMS: Previous studies have associated issues such as incomplete stent apposition with delayed healing and adverse events (stent thrombosis). The aim of this study was to evaluate the impact of strut apposition and stent type on the progression of stent strut coverage. METHODS AND RESULTS: We evaluated in vivo in porcine models the follow-up response and coverage characteristics of well-apposed and malapposed segments of drug-eluting stents (DES) (CYPHER, PROMUS Element and Orsiro) and the Absorb bioresorbable vascular scaffold (BVS) by optical coherence tomography (OCT) sequentially, at baseline, and at one week and four weeks of follow-up. Supporting results were provided by histological analysis performed at four-week follow-up and computer simulation describing the shear characteristics around apposed and non-apposed struts. A total of 325 cross-sections containing 3,166 struts were analysed. The extent of malapposition decreased over time as a result of neointimal healing (from 7.1% at baseline to 0% at four weeks; p=0.03). At one week, 13.6% of struts in well-apposed segments were still uncovered versus 19.2% of struts in malapposed cross-sections and 77.8% of NASB struts (p<0.01). At four-week follow-up, 3.1% of struts were uncovered in well-apposed cross-sections vs. 1.6% in malapposed cross-sections and 35.7% of NASB struts (p<0.01). A comparison of the apposed segments revealed that the thin-strut Orsiro had only 1.3% of uncovered struts at one week while PROMUS Element, CYPHER and BVS had 6.6%, 48.4% and 16.2% of struts still uncovered, respectively. CONCLUSIONS: This study shows that early coverage is influenced by stent apposition as well as platform strut characteristics (stent type). At four weeks, NASB struts remained a focus of delayed endothelialisation.
