RESUMO

OBJECTIVE: To characterise and compare off-road motorcycle and quad bike crashes in children in New South Wales (NSW), Australia. METHODS: A retrospective, cross-sectional study was performed of children aged 0-16 years, admitted to hospitals in NSW, from 2001 to 2018 following an injury sustained in an off-road motorcycle or quad bike crash, using linked hospital admissions, mortality and census data.Motorcycle and quad bike injuries were compared regarding: demographics; incidence; body region injured and type of injury; injury severity based on the survival risk ratio; length of stay and mortality. RESULTS: There were 6624 crashes resulting in hospitalisation; 5156 involving motorcycles (77.8%) and 1468 involving quad bikes (22.2%). There were 10 fatalities (6 from motorcycles and 4 from quad bikes). The rates of injury declined over the study period for motorcycles, but not for quad bikes.Motorcycle riders were more likely than quad bike riders to have lower limb injuries (OR 1.49, p<0.001) but less likely to have head/neck (OR 0.616, p<0.001), abdominal (OR 0.778, p=0.007) and thoracic (OR 0.745, p=0.003) injuries. Quad bike crashes resulted in higher injury severity (mean International Classification Injury Severity Score 0.975 vs 0.977, p=0.03) and longer hospital stay (mean 2.42 days vs 2.09 days, p=0.01). CONCLUSIONS: There are significant differences between quad bike and motorcycle crashes in injury type and affected body region. While quad bike injuries in children were more severe, there were almost four times more hospitalisations from motorcycles overall. The overall larger burden of motorcycle crashes suggests a greater focus of injury prevention countermeasures for two-wheeled riders is needed.

RESUMO

In end-stage ankle arthritis, little is known about the impact of concomitant knee pathology, including the impact of ipsilateral knee pain on total ankle arthroplasty (TAA) outcomes. The aim of this study was to determine the prevalence of ipsilateral preoperative knee pain in patients undergoing TAA and analyze its impact on patient-reported functional outcome measures (PROMs). A retrospective review was performed on the Vancouver End Stage Ankle Arthritis Database at a single institution. In total, 114 patients were studied, with patient demographics collected preoperatively, including the presence or absence of knee pain. Postoperative follow-up was performed at 5 years, primarily analyzing disease-specific PROMs, including the Ankle Osteoarthritis Score (AOS) and Ankle Arthritis Score (AAS). Multivariate mixed-effects linear regression models compared the scores between the groups. In total, 31 patients (27.2%) presented with concomitant ipsilateral knee pain. Despite more females in the knee pain group (64.5% vs 36.1%) there were no other significant differences at baseline between the knee pain and no knee pain groups in terms of demographics or baseline primary disease specific PROMs. At 5 years, the patients with knee pain had significantly worse AAS (37.9 ± 23.8 vs 21.2 ± 16.3, P = .004) and AOS total scores (38.1 ± 24.1 vs 21.9 ± 15.5, P = .005) compared with the no-knee pain group. Both groups improved significantly from baseline across all outcome measures; however, the magnitude of improvement was less in the knee pain group. Our study demonstrated that over one-quarter of patients with end-stage ankle arthritis undergoing TAA present with ipsilateral concomitant knee pain. If present, it is associated with worse functional outcomes at the 5-year mark. Further studies are needed to evaluate if knee pain influences complications, implant failure rates, and survival.Levels of Evidence: Level III.

RESUMO

OBJECTIVE: Off-road riding of quad bikes and motorcycles is common among children across rural and remote Australia, but is a significant source of injury and hospitalisation. An in-depth analysis of paediatric off-road vehicle crashes was undertaken to inform injury prevention countermeasures by characterising injury patterns and sources of injury. DESIGN: This is a prospective in-depth case series. PARTICIPANTS: Participants are children aged 16 and under who have been hospitalised due to injury sustained from the use of an off-road motorcycle or quad bike in New South Wales, Australia. INTERVENTIONS: Crash investigation techniques (medical data, structured interview, vehicle and crash site inspection) were used to ascertain details of the crash event, protective gear, injury information and contributory factors. RESULTS: Thirty children were recruited, 27 boys and 3 girls, ranging in age from 4 to 16 years, having crashed on off-road motorcycles (n = 27) or quads (n = 3). Most (73.3%) were participating in unstructured social riding. A total of 67 separate injuries were observed, with overall Injury Severity Scores between 1 and 35. There were high rates of wearing helmets and motorcycle-specific garments. The most commonly injured areas were the upper and lower extremities. The most common sources of injury were from impacting the ground, obstacles/other riders or the vehicle. CONCLUSION: This study demonstrates the patterns of riding and injury in rural paediatric off-road vehicle riders, occurring despite high rates of helmet/protective gear use. This underscores the need for investigation into the injury mitigation and fit properties of protective gear and the inherent risks for physically and developmentally maturing children.

RESUMO

Although numerous studies have demonstrated that concomitant low back pain (LBP) is associated with worse functional outcomes in patients undergoing total hip and knee arthroplasty, no study has analyzed its impact on patients undergoing total ankle arthroplasty (TAA). The aim of this study was to determine the prevalence of LBP in people undergoing TAA and analyze its impact on patient reported functional outcome measures (PROMs). A retrospective review was performed on data from the Vancouver End Stage Ankle Arthritis Database. In total, 87 patients undergoing TAA were studied, with patient demographics collected preoperatively, including the absence or presence of LBP. Postoperative follow-up was performed at 5 years, primarily analyzing disease-specific PROMs including the Ankle Osteoarthritis Score and Ankle Arthritis Score. The Short Form-36 was used as a secondary outcome measure to assess global function. Multivariable linear mixed-effects regression models were conducted to compare the PROM between patients with LBP with those without LBP. In total, 30 patients (35%) presented with concomitant LBP. There were no significant differences at baseline between the LBP group and no LBP group in terms of demographics or baseline primary disease-specific PROMs. At 5 years, the patients with LBP had significantly worse Ankle Arthritis Score (32 ± 23 vs 22 ± 17, p = .03), Ankle Osteoarthritis Score Total (34 ± 23 vs 22 ± 16, p = .01), and Short Form-36 physical (PCS) components summaries (33 ± 12 vs 44 ± 9, p = .001) compared to the no-LBP group. Both groups improved significantly from baseline across all outcome measures. Our study demonstrated that the prevalence of concomitant LBP in end stage ankle arthritis undergoing TAA is similar to that described in arthritic knees and hips. If present, it can be associated with worse functional outcomes in the intermediate term. However it is not a contraindication to surgery, with patients still experiencing significant improvements from baseline. Further studies are needed to evaluate if LBP influences complications, implant failure rates and survival.

RESUMO

AIM: Falls in infants are a common cause of injury. Compared to older children, infants under age one are likely to have distinctive causation and injury patterns, as they are pre-mobile or have limited independent mobility and falls are more directly the responsibility of the care giver. There is little known about the mechanistic factors, predictors of injury and injury patterns in this age group. METHODS: We conducted a retrospective review of infants under age one who presented after a fall to a paediatric trauma centre in Sydney, Australia. Circumstances and mechanisms of the fall, injury patterns, burden of investigations and outcomes were analysed. RESULTS: Over a 3-year period (2011-2013), 916 infants presented following a fall. One hundred and six (11.6%) were admitted and there was one death. Head injury was the most common reason for admission (85%). While there were severe and critical head injuries (Abbreviated Injury Scale 4-5) these were infrequent (2% of presentations). All admitted cases involved a short distance fall. Patients dropped by others were three times more likely to be admitted than infants presenting following other fall types (95% CI 1.9-4.8). Compared to other mechanisms, patients who fell from furniture had significantly longer hospital stays. CONCLUSIONS: Fall mechanisms involving infants being dropped by adults, and falls from beds or couches carry the highest clinical burden. These mechanisms should be targets for injury prevention and inform the design of safe equipment and environments for babies.

RESUMO

Indoor trampoline parks are increasing as a source of injuries among children. We conducted a prospective cohort study, with semi-structured interview and medical record review, of children aged <17 years presenting to a paediatric emergency department following an injury at an indoor trampoline park. In a 6-month period in 2014, 40 such children (55% female) presented to the department. Common mechanisms were individual jumpers falling while attempting a somersault or trick, landing awkwardly on an obstacle such as a ball or protective padding, and multiple users on a single trampoline. Most sustained soft tissue injuries (n=22, 55%) and fractured bones (n=15, 37.5%). One child sustained an unstable cervical fracture/dislocation. Unlike domestic trampolines, where the majority of injuries occur from falling off, most trampoline-park injuries occur on the trampoline surface. These differences require injury prevention strategies that engage children, carers and businesses to meet best practice design and management standards.

RESUMO

We analyzed patients with small B-cell clonal populations in a non-hospital based pathology laboratory servicing metropolitan and regional areas of New South Wales, Australia. There were 414 patients with a finding of a B-cell clone with total B-lymphocytes < 5.0 × 10(9)/L, fulfilling the criteria for monoclonal B-lymphocytosis (MBL). There were 212 males (51%) and 202 females (49%) with a mean age of 69.7 years. Patients could be clearly divided into two dominant groups: 322 (77.7%) with a typical chronic lymphocytic leukemia (CLL) phenotype, MBL[cll], and 92 (22.3%) with a "non-CLL" or lymphoma-like phenotype, MBL[nhl]. Analysis of MBL[cll] showed 168 (52.2%) males and 154 (47.8%) females with a mean age of 70.6 years. The mean clonal level (CD19/CD5+) was 2.36 × 10(9)/L and the absolute lymphocyte count (ALC) was 0.4-10.5 × 10(9)/L. The ALC was within the reference range (1.0-4.0 × 10(9)/L) in 22%. The 92 patients with MBL[nhl] were 44 (47.8%) males and 48 (52.2%) females, with a mean age of 66.7 years. The mean clonal level was 1.27 × 10(9)/L. There were 65 patients with a "lymphoma unclassifiable" clone and the remainder had a probable disease-specific diagnosis. In a large community cohort of patients, MBL can be divided into two dominant groups, MBL[cll] and the more heterogeneous MBL[nhl].
