Abstract
First aid cooling for burn injuries improves re-epithelialisation rates and reduces scarring. The objective of this research was to explore and describe barriers and facilitators to the provision of optimal first aid for acute burn patients in the prehospital setting. Emergency medical service (EMS) clinicians in Queensland were invited via email to participate in a survey designed to assess experience, knowledge, and attitudes regarding provision of optimal burn first aid in the prehospital setting (N = 4500). Barriers and facilitators to administering optimal first aid in the prehospital environment were assessed via two open-ended questions with free-text response boxes. An inductive approach to qualitative content analysis was used to analyze free-text data. In total, we included 326 respondents (7.2% response rate). Responses (n = 231) regarding barriers to first aid were classified into 12 categories, within five overarching dimensions. The most common of these was identified as pain. Similarly, free text responses (n = 276) regarding facilitators of burn first aid formed eight dimensions with 21 subcategories - most commonly fast and effective pain relief. Factors influencing burn first aid provision in the prehospital setting were wide-ranging and varied, with pain identified as the most prominent.

Abstract
BACKGROUND Hospital-acquired pressure injuries (HAPIs) pose significant challenges in healthcare and cause increased patient suffering, longer hospital stays, and higher healthcare costs. Paediatric patients face unique risks, but evidence remains scarce. This study aimed to identify and describe HAPI admission incidence and severity predictors in a large Australian children's hospital. METHODS This retrospective cohort study investigated all paediatric patients between January 2020 and December 2021 using a census approach. Demographic and clinical data including HAPI-related data were accessed from the incident monitoring and hospital administration databases. The incidence rate (per 1000 patient admissions) was calculated based on all admissions. Predictors of HAPI severity were identified using multivariable multinomial logistic regression. The study adhered to the STROBE guidelines for retrospective cohort studies. RESULTS The HAPI incidence rate was 6.96 per 1000 patient admissions. Of the age groups, neonates had the highest HAPI incidence (15.5 per 1000 admissions). Critically ill children had the highest rate for admission location (12.8 per 1000 patient admissions). Most reported cases were stage I (64.2%). Age was associated with injury severity, with older paediatric patients more likely to develop higher-stage HAPIs. Additionally, Aboriginal and/or Torres Strait Islander patients had a higher HAPI severity risk. CONCLUSION HAPI injuries in paediatric patients are unacceptably high. Prevention should be prioritized, and the quality of care improved in Australia and beyond. Further research is needed to develop targeted prevention strategies for these vulnerable populations. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE This research emphasizes the need for standardized reporting, culturally sensitive care and tailored prevention strategies. IMPACT The research has the potential to influence healthcare policies and practices, ultimately enhancing the quality of patient care. REPORTING METHOD STROBE guidelines. NO PATIENT OR PUBLIC CONTRIBUTION There was no patient or public contribution to the conduct of this study.

Abstract
PURPOSE To optimise care pathways and provide greater transparency of the psychosocial needs of injured children after hospital discharge by extending post-discharge psychosocial screening to children admitted with traumatic injury for ≥24 h. DESIGN AND METHODS This mixed-methods study used a co-design approach informed by the Experience-Based Co-design (EBCD) framework. Interviews with carers were used to evaluate experiences and generate views on psychosocial support interventions. Online surveys by international child psychologists' indicated preferences for a psychosocial screening tool, and clinician-stakeholder consensus meetings facilitated the development of an electronic post-injury psychosocial screening tool. RESULTS Carers found the initial year of follow-up from trauma family support services helpful, appreciating the hospital connection. Flexible follow-up timings and additional resources were mentioned, and most carers were interested in participating in an electronic screening activity to predict their child's coping after injury. Child trauma experts recommended including several screening tools, and the multidisciplinary paediatric trauma service and study investigators collaborated over a year to workshop and reach a consensus on the screening tool and follow-up process. CONCLUSION The multidisciplinary team co-designed an electronic psychosocial screening and follow-up process for families with children with traumatic injuries. This tool improves the visibility of injured children's psychosocial needs post-injury and potentially aids clinical targeted resource allocation for trauma family support services. PRACTICE IMPLICATIONS The study emphasises the significance of specialised psychosocial screening tools in paediatric nursing, especially in trauma care, for understanding patients' psychosocial needs, tailoring follow-up plans, and promoting a patient-centred approach.

Abstract
AIM This qualitative study aimed to identify nurses' and allied health professionals' perceptions and experiences of providing hospital-acquired pressure injury (HAPI) prevention in a paediatric tertiary hospital in Australia, as well as understand the perceived barriers and facilitators to preventing HAPI. DESIGN A qualitative, exploratory study of hospital professionals was undertaken using semi-structured interviews between February 2022 and January 2023. METHODS Two frameworks, the Capability, Opportunity and Motivation Model of Behaviour (COM-B) and the Theoretical Domains Framework (TDF), were used to give both theoretical and pragmatic guidance. Participants included 19 nursing and allied health professionals and data analysis was informed by the framework approach. RESULTS Analysis revealed nine core themes regarding professionals' beliefs about the barriers and facilitators to HAPI prevention practices across seven TDF domains. Themes included HAPI prevention skills and education, family-centred care, automated feedback and prompts, allocation and access to equipment, everybody's responsibility, prioritizing patients and clinical demands, organizational expectations and support, integrating theory and reality in practice and emotional influence. CONCLUSION These findings provide valuable insights into the barriers and facilitators that impact paediatric HAPI prevention and can help identify and implement strategies to enhance evidence-based prevention care and prevent HAPI in paediatric settings. IMPACT Overcoming barriers through evidence-based interventions is essential to reduce HAPI cases, improve patient outcomes, and cut healthcare costs. The findings have practical implications, informing policy and practice for improved preventive measures, education, and staffing in paediatric care, ultimately benefiting patient well-being and reducing HAPIs. PATIENT OR PUBLIC CONTRIBUTION No patient or public contribution. The focus of the study is on healthcare professionals and their perspectives and experiences in preventing HAPIs in paediatric patients. Therefore, the involvement of patients or the public was not deemed necessary for achieving the specific research objectives.

Abstract
BACKGROUND Pediatric extravasation injuries are significant healthcare-associated injuries, with sometimes significant sequelae. Evidence-based guidance on management is necessary to prevent permanent injury. PURPOSE A systematic review of the literature, including aggregated case series, investigating extravasation injury management of hospitalized pediatric patients. DATA SOURCES PubMed, Cummulative Index to Nursing and Allied Health Literature (CINAHL), and Excerpta Medica database (EMBASE) were searched on December 13, 2021. STUDY SELECTION Primary research investigating extravasation injury management of hospitalized pediatric patients (to 18 years), published from 2010 onwards and in English, independently screened by two authors, with arbitration from a third author. DATA EXTRACTION Data regarding the study, patient (age, primary diagnosis), extravasation (site, presentation, outcome), and treatment (first aid, wound management) were extracted by two authors, with arbitration from a third author. DATA SYNTHESIS From an initial 1769 articles, 27 studies were included with extractable case data reported in 18 studies, resulting in 33 cases. No clinical trials were identified, instead, studies were primarily case studies (52%) of neonates (67%), with varied extravasation symptoms. Studies had good selection and ascertainment, but few met the causality and reporting requirements for quality assessments. Signs and symptoms varied, with scarring (45%) and necrosis (30%) commonly described. Diverse treatments were categorized into first aid, medical, surgical, and dressings. CONCLUSIONS Despite infiltration and extravasation injuries being common within pediatric healthcare, management interventions are under-researched, with low-quality studies and no consensus on treatments or outcomes.

Abstract
BACKGROUND Oedema measurement, also termed sub-epidermal moisture measurement is recommended as an adjunct pressure injury prevention intervention in international guidelines because it indicates early tissue damage. OBJECTIVE To determine the prognostic value of oedema measurement in predicting future pressure injury in adults in any care setting. DESIGN Systematic review and meta-analysis. SETTING Participants were recruited from nursing homes or aged care facilities, hospitals, or post-acute facilities. PARTICIPANTS Adults. METHODS A modified 2-week systematic review was undertaken. Study designs included cohort (prospective and retrospective), case-control, case series if relevant comparisons were reported, randomised controlled trials if the association between oedema measurement and pressure injury was reported, and registry data. Databases searched included: Medical Literature Analysis and Retrieval System Online, The Cumulative Index to Nursing and Allied Health Literature, Excerpta Medica and the Cochrane Library from inception to 13 July 2021 with no language restrictions. Screening, data extraction using Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies - Prognostic Factors (CHARMS-PF) and quality assessment using Quality in Prognostic Factor Studies (QUIPS) were undertaken independently by ≥2 authors and adjudicated by another if required. Meta-analyses and meta-regression were undertaken. The certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS Six studies (n = 483 total) were included. Two studies were set in nursing homes and four in either hospitals or post-acute facilities. Fives studies were prospective cohorts, and one was a randomised control trial. Two studies were assessed as low risk and four studies as moderate risk of bias. The pooled risk ratio in four studies (n = 388) for the relationship between oedema and pressure injury cumulative incidence was 18.87 (95% CI 2.13-38.29) and for time to pressure injury was 4.08 days (95% CI 1.64-6.52). Using GRADE, the certainty of the body of evidence was low for all outcomes. Meta-regression indicated that age, gender, and sample size were poor predictors for the association between oedema and pressure injury. CONCLUSIONS Measuring oedema as a predictor for pressure injury development is showing promise but a stronger body of evidence that takes into consideration other prognostic factors is needed to better understand its benefit. REGISTRATION PROSPERO CRD42021267834. TWEETABLE ABSTRACT Measuring oedema is a promising strategy to prevent pressure injuries but the certainty of evidence for this claim is low.

Abstract
Abstract
Introduction
Reported advantages of early excision for larger burn injuries include reduced morbidity, mortality, and hospital length of stay for adult burn patients. However, a paucity of evidence supports the best option for paediatric burns and the advantages of non-excisional (mechanical) debridement. This study aims to evaluate the association between early (< 24hours post-injury) non-excisional debridement under general anaesthesia with burn wound re-epithelialisation time and skin graft requirements.
Methods
A cohort study of children (< 17 years) presenting with burns >5% total body surface area, using prospectively collected state-wide pediatric burns' registry between January 2013 to December 2019. Primary outcomes were: time to reepithelialization (tested using survival analysis) and skin graft requirements, tested using binary logistic regression for odds ratios). Using depth and size, we performed a propensity matched dataset to analyse effects of early non-excisional debridement in the operating theatre.
Results
Overall, 392 children met eligibility (males 58.2%). When propensity matched, early non-excisional debridement under general anaesthesia in the operating theatre, significantly reduced the time to re-epithelialisation (15.0 (CI: 11.00-20.00) versus 20.0 (CI:13.5 – 31.00) days) and the odds of requiring a skin graft (OR:0.319 (0.125 – 0.812).
Conclusions
This study is the first to demonstrate that early non-excisional debridement under general anaesthesia in the operating theatre significantly reduces wound re-epithelialisation time and subsequent need for a skin graft in paediatric burn patients. Analysis suggests that ketamine procedural sedation and analgesia in the emergency department used for burn wound debridement is not an effective substitute for debridement in the operating theatre.

Abstract
OBJECTIVE To compare the effectiveness of two acute burn dressings, Burnaid hydrogel dressing and plasticised polyvinylchloride film, on reducing acute pain scores in paediatric burn patients following appropriate first aid. DESIGN Single-centre, superiority, two-arm, parallel-group, prospective randomised controlled trial. PARTICIPANTS AND SETTING Paediatric patients (aged ≤16) presenting to the Emergency Department at the Queensland Children's Hospital, Brisbane, Australia, with an acute thermal burn were approached for participation in the trial from September 2017-September 2018. INTERVENTIONS Patients were randomised to receive either (1) Burnaid hydrogel dressing (intervention) or (2) plasticised polyvinylchloride film (Control) as an acute burn dressing. PRIMARY AND SECONDARY OUTCOMES Observational pain scores from nursing staff assessed 5 min post application of the randomised dressing, measured using the Face Legs Activity Cry and Consolability Scale was the primary outcome. Repeated measures of pain, stress and re-epithelialisation were also collected at follow-up dressing changes until 95% wound re-epithelialisation occurred. RESULTS Seventy-two children were recruited and randomised (n=37 intervention; n=35 control). No significant between-group differences in nursing (mean difference: -0.1, 95% CI -0.7 to 0.5, p=0.72) or caregiver (MD: 1, 95% CI -8 to 11, p=0.78) observational pain scores were identified. Moreover, no significant differences in child self-report pain (MD: 0.3, 95% CI -1.7 to 2.2, p=0.78), heart rate (MD: -3, 95% CI -11 to 5, p=0.41), temperature (MD: 0.6, 95% CI -0.13 to 0.24, p=0.53), stress (geometric mean ratio: 1.53, 95% CI 0.93 to 2.53, p=0.10), or re-epithelialisation rates (MD: -1, 95% CI -3 to 1, p=0.26) were identified between the two groups. CONCLUSIONS A clear benefit of Burnaid hydrogel dressing as an analgesic adjunct to first aid for the treatment of acute paediatric burns was not identified in this investigation. TRIAL REGISTRATION NUMBER Australian New Zealand Clinical Trials Registry (ACTRN12617001274369).

Abstract
Negative pressure wound therapy has been used to promote wound healing in a variety of settings, including as an adjunct to silver-impregnated dressings in the acute management of paediatric burns. Fluid aspirated by the negative pressure wound therapy system represents a potentially insightful research matrix for understanding the burn wound microenvironment and the intervention's biochemical mechanisms of action. The aim of this study was to characterize the proteome of wound fluid collected using negative pressure wound therapy from children with small-area thermal burns. Samples were obtained as part of a randomized controlled trial investigating the clinical efficacy of adjunctive negative pressure wound therapy. They were compared with blister fluid specimens from paediatric burn patients matched according to demographic and injury characteristics. Protein identification and quantification were performed via liquid chromatography tandem mass spectrometry and sequential window acquisition of all theoretical mass spectra data-independent acquisition. Proteins and biological pathways that were unique to or enriched in negative pressure wound therapy fluid samples were evaluated using principal components, partial least squares-discriminant, and gene ontology enrichment analyses. Eight viable samples of negative pressure wound therapy fluid were collected and analyzed with eight matched blister fluid samples. A total of 502 proteins were quantitatively profiled in the negative pressure wound therapy fluid, of which 444 (88.4%) were shared with blister fluid. Several proteins exhibited significant abundance differences between fluid types, with negative pressure wound therapy fluid showing a higher abundance of matrix metalloproteinase-9, arginase-1, low affinity immunoglobulin gamma Fc region receptor III-A, filamin-A, alpha-2-macroglobulin, and hemoglobin subunit alpha. The results lend support to the hypothesis that negative pressure wound therapy augments wound healing through the modulation of factors involved in the inflammatory response, granulation tissue synthesis, and extracellular matrix maintenance. Data are available via ProteomeXchange with identifier PXD023168.

Abstract
INTRODUCTION There is an absence of evidence regarding predictors of moderate to severe pain in children undergoing acute burn treatment. This investigation aimed to determine if relationships existed between patient and clinical characteristics, and pain at first dressing change for children with acute burn injuries. METHODS A retrospective cohort investigation was conducted using clinical data from pediatric burn patients treated at the Queensland Children's Hospital, Brisbane, Australia. Data extracted included patient and burn characteristics, first aid, and follow-up care. Observational pain scores were categorized into three groups (mild, moderate, and severe pain), and bivariate and multivariable relationships were examined using proportional odds ordinal logistic regression. Data from 2013 pediatric burns patients were extracted from the database. RESULTS Factors associated with increased odds of procedural pain included: hand burns (OR 1.7, 95% CI 1.3 to 2.1, p<0.001), foot burns (OR 1.5, 95% CI 1.1 to 2.1, p<0.01), baseline pain (OR 5.5, 95% CI 2.8 to 10.8, p<0.001), deep dermal partial-thickness injuries (OR 7.9, 95% CI 4.0 to 15.6, p<0.001), increased burn size (OR 1.1, 95% CI 1.0 to 1.2, p<0.01), four or more anatomical regions burned (OR 3.6, 95% CI 1.5 to 8.6, p<0.01), initial treatment at a non-burns center (OR 1.8, 95% CI 1.4 to 2.3, p<0.001), and time to hospital presentation (OR 0.9, 95% CI 0.8 to 0.9, p<0.001). These burn characteristics are associated with increased odds of moderate to severe procedural pain during a child's first dressings change. DISCUSSION It is recommended that patients presenting with one or more of the aforementioned factors are identified before their first dressing change, so additional pain control methods can be implemented.

Abstract
Background The efficacy of negative pressure wound therapy (NPWT) in the acute management of burns remains unclear. The purpose of this trial was to compare standard Acticoat™ and Mepitel™ dressings with combined Acticoat™, Mepitel™ and continuous NPWT to determine the effect of adjunctive NPWT on re‐epithelialization in paediatric burns. Methods This two‐arm, single‐centre RCT recruited children with acute thermal burns covering less than 5 per cent of their total body surface area. The primary outcome was time to re‐epithelialization. Blinded assessments were performed using photographs captured every 3–5 days until discharge. Secondary measures included pain, itch, grafting, perfusion and scar management referrals. Results Some 114 patients were randomized. Median time to re‐epithelialization was 8 (i.q.r. 7–11) days in the NPWT group and 10 (8–14) days in the control group. In a multivariable model, NPWT decreased the expected time to wound closure by 22 (95 per cent c.i. 7 to 34) per cent (P = 0·005). The risk of referral to scar management was reduced by 60 (18 to 81) per cent (P = 0·013). Four participants in the control group and one in the NPWT group underwent grafting. There were no statistically significant differences between groups in pain, itch or laser Doppler measures of perfusion. Adverse events were rare and minor, although NPWT carried a moderate treatment burden, with ten patients discontinuing early. Conclusion Adjunctive NPWT hastened re‐epithelialization in small‐area burn injuries in children, but had a greater treatment burden than standard dressings alone.

Abstract
PURPOSE Nurses provide care at each phase of the complex, perioperative pathway and are well placed to identify areas of care requiring investigation in randomized controlled trials. Yet, currently, the scope of nurse-led randomized controlled trials conducted within the perioperative setting are unknown. This scoping review aims to identify areas of perioperative care in which nurse-led randomized controlled trials have been conducted, to identify issues impacting upon the quality of these trials and identify gaps for future investigation. METHODS This scoping review was conducted in reference to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. Searches were conducted in PubMed, Embase, Cumulative Index for Nursing and Allied Health Literature and the Cochrane Central Register of Controlled Trials, with a date range of 2014-19. Sources of unpublished literature included Open Grey, and ProQuest Dissertation and Theses, Clinical Trials.gov and the Australian and New Zealand Clinical Trials Registry. After title and abstract checking, full-text retrieval and data extraction, studies were appraised using the Joanna Briggs Institute Critical Appraisal Checklists for randomized controlled trials. Data were synthesized according to the main objectives. Key information was tabulated. RESULTS From the 86 included studies, key areas where nurses have led randomized controlled trials include patient or caregiver anxiety; postoperative pain relief; surgical site infection prevention: patient and caregiver knowledge; perioperative hypothermia prevention; postoperative nausea and vomiting; in addition to other diverse outcomes. Issues impacting upon quality (including poorly reported randomization), and gaps for future investigation (including a focus on vulnerable populations), are evident. CONCLUSION Nurse-led randomized controlled trials in the perioperative setting have focused on key areas of perioperative care. Yet, opportunities exist for nurses to lead experimental research in other perioperative priority areas and within different populations that have been neglected, such as in the population of older adults undergoing surgery.

Abstract
STUDY OBJECTIVE First-aid guidelines recommend the administration of cool running water in the early management of thermal injury. Our objective is to analyze the associations between first aid and skin-grafting requirements in children with burns. METHODS This cohort study used a prospectively collected registry of patients managed at a tertiary children's hospital. Multivariate logistic regression models were used to evaluate the relationship between first aid and the requirement for skin grafting. Secondary outcomes included time to re-epithelialization, wound depth, hospital admission and length of stay, and operating room interventions. Adequate first aid was defined as 20 minutes of cool running water within 3 hours of injury. RESULTS In our cohort of 2,495 children, 2,259 (90.6%) received first aid involving running water, but only 1,780 (71.3%) were given the adequate duration. A total of 236 children (9.5%) required grafting. The odds of grafting were decreased in the adequate first aid group (odds ratio [OR] 0.6; 95% confidence interval [CI] 0.4 to 0.8). The provision of adequate running water was further associated with reductions in full-thickness depth (OR 0.4; 95% CI 0.2 to 0.6), hospital admission (OR 0.7; 95% CI 0.3 to 0.9), and operating room interventions (OR 0.7; 95% CI 0.5 to 0.9), but not hospital length of stay (hazard ratio=0.9; 95% CI 0.7 to 1.2; P=.48). CONCLUSION Burn severity and clinical outcomes improved with the administration of cool running water. Adequate first aid must be prioritized by out-of-hospital and emergency medical services in the preliminary management of pediatric burns.

Abstract
Background Burns are a painful and traumatic experience, particularly in children. Reduced pain and anxiety positively influences re-epithelialisation rates in paediatric burn patients, however current literature fails to fully explain the effects of pain and anxiety and their links with wound healing. This study will determine if Burnaid® hydrogel dressing is an effective treatment for reducing pain in the acute period of a burn injury. It is hypothesised that a reduction in pain will then improve re-epithelialisation time in comparison to plastic wrap, which is standard practice at our institution — a metropolitan tertiary paediatric hospital located in Brisbane, Australia. Methods/design A randomised controlled trial will be conducted to assess the effectiveness of Burnaid® as an analgesic adjunct to cold running water first aid for the treatment of paediatric burns. Participants will include children aged between 0 and 16 years with an acute thermal burn injury (total burn surface area < 20%) presenting to the Department of Emergency within 24 h of the burn occurring. Participants will be randomised into one of two groups: (1) Burnaid® hydrogel (intervention arm) or (2) plastic wrap (control arm). Participants will also be stratified into one of two groups based on factors that influence pain intensity: (1) high pain risk or (2) low pain risk. High pain risk factors include foot burns, hot coal/ash/fire pit burns, burn area greater than 5%, and circumferential burns. The primary outcome is the intervention’s effect on reducing acute pain. Secondary outcomes include days to re-epithelialisation, pulse rate, temperature, salivary cortisol and α-amylase, anxiety, and cost-effectiveness. Sample size calculations have shown that 36 participants will be recruited into each group. Discussion This study will provide comprehensive data on the analgesic properties of Burnaid® as an adjunct to first aid for the treatment of acute paediatric thermal burns. If the intervention is effective in reducing pain, Burnaid® will be integrated as standard practice within the hospital’s Department of Emergency. This study replicates a real-world scenario in order to identify clinically significant analgesic and wound-healing effects.

Abstract
INTRODUCTION The main objective of this study is to describe incidence rates of low-speed vehicle run-over (LSVRO) events among children aged 0-14 years residing in Queensland from 1999 to 2009. A second objective was to describe the associated patterns of injury, with respect to gender, age group, severity, characteristics (host, vehicle and environment), and trends over time in relation to geographical remoteness. Final results are hoped to inform prevention policies. METHODS In this statewide, retrospective, population-based study, data were collected on LSVRO events that occurred among children aged 0-14 years in Queensland from 1999 to 2009 from all relevant data sources across the continuum of care, and manually linked to obtain the most comprehensive estimate possible of the magnitude and nature of LSVRO events to date. Crude incidence rates were calculated separately for males and females, for fatal events, non-fatal events (hospital admissions and non-admissions, respectively), and for all LSVRO events, for each area of geographical remoteness (major cities, inner regional, outer regional, remote/very remote). Relative risks and 95% confidence interval were calculated, and trends over time were examined. Data on host, injury and event characteristics were also obtained to investigate whether these characteristics varied between areas of remoteness. RESULTS Incidence rates were lowest among children (0-14 years) living in major cities (13.8/100 000/annum, with the highest recorded incidence in outer regional areas (incidence rate =42.5/100 000/annum). Incidence rates were higher for children residing outside major cities for both males and females, for every age group, for each of the 11 years of the study, and consequences of LSVRO events were worse. Young children aged 0-4 years were identified as those most at risk for these events, regardless of geographical location. Differences were observed as a function of remoteness category in relation to injury characteristics (eg injury type), and host characteristics (eg sociodemographic status), but there were no observed differences in environmental characteristics (eg time of day, day of week). Heavy vehicles such as four-wheel drives, utilities, trucks and tractors were more frequently involved in LSVRO events that occurred outside major cities. CONCLUSION The results confirmed that children of all ages and genders residing outside of major cities in Queensland are more at risk of being involved in an LSVRO incident, and experience more severe consequences compared to children in major cities. Future research should address the specific risk factors and focus on engaging rural communities to assist in the prevention of LSVRO incidents.

Abstract
BACKGROUND The purpose of this study was to estimate the incidence of fatal and non-fatal Low Speed Vehicle Run Over (LSVRO) events among children aged 0-15 years in Queensland, Australia, at a population level. METHODS Fatal and non-fatal LSVRO events that occurred in children resident in Queensland over eleven calendar years (1999-2009) were identified using ICD codes, text description, word searches and medical notes clarification, obtained from five health related data bases across the continuum of care (pre-hospital to fatality). Data were manually linked. Population data provided by the Australian Bureau of Statistics were used to calculate crude incidence rates for fatal and non-fatal LSVRO events. RESULTS There were 1611 LSVROs between 1999-2009 (IR=16.87/100,000/annum). Incidence of non-fatal events (IR=16.60/100,000/annum) was 61.5 times higher than fatal events (IR=0.27/100,000/annum). LSVRO events were more common in boys (IR=20.97/100,000/annum) than girls (IR=12.55/100,000/annum), and among younger children aged 0-4 years (IR=21.45/100000/annum; 39% or all events) than older children (5-9 years: IR=16.47/100,000/annum; 10-15 years IR=13.59/100,000/annum). A total of 896 (56.8%) children were admitted to hospital for 24 hours of more following an LSVRO event (IR=9.38/100,000/annum). Total LSVROs increased from 1999 (IR=14.79/100,000) to 2009 (IR=18.56/100,000), but not significantly. Over the 11 year period, there was a slight (non -significant) increase in fatalities (IR=0.37-0.42/100,000/annum); a significant decrease in admissions (IR=12.39-5.36/100,000/annum), and significant increase in non-admissions (IR=2.02-12.77/100,000/annum). Trends over time differed by age, gender and severity. CONCLUSION This is the most comprehensive, population-based epidemiological study on fatal and non-fatal LSVRO events to date. Results from this study indicate that LSVROs incur a substantial burden. Further research is required on the characteristics and risk factors associated with these events, in order to adequately inform injury prevention. Strategies are urgently required in order to prevent these events, especially among young children aged 0-4 years.

Abstract
Channel catfish, Ictalurus punctatus (Rafinesque), with or without a preliminary 24 h exposure to 2 mg copper sulphate L(-1), were challenged with 7.5 x 10(6) colony forming units L(-1) of Edwardsiella ictaluri to determine the effect of copper sulphate on disease resistance. Catfish previously exposed to copper sulphate were significantly more resistant to the bacterial challenge than those not exposed. Catfish not exposed to copper sulphate suffered 35.5% mortality while catfish exposed to copper sulphate experienced 14.1% mortality. Copper concentrations were the same in tank waters of both exposed and control fish at the time of challenge, eliminating the possibility that copper in the water may have been toxic to bacteria. Copper concentrations in freeze dried and ground tissues of unexposed, exposed, and purged channel catfish were highest in fish before copper sulphate exposures suggesting that elevated tissue levels of copper were not responsible for the increased resistance to bacterial challenge. Competition for sites of bacterial attachment to gill or epithelial cells may account for the reduction in mortality; although this is not supported by the low copper content of fish tissue after copper exposure.

Abstract
Channel catfish virus (CCV) produces an acute haemorrhagic disease in fingerling channel catfish and establishes latent infection in fish that survive the primary infection. This study investigated CCV gene expression in tissues of experimentally infected fish. Reverse transcriptase polymerase chain reaction assays were developed for detection of transcripts expressed by each of the CCV direct repeat region genes in CCV-infected channel catfish ovary cells and in tissues of infected fish. Immediate-early, early and late gene transcripts were detected in the blood, brain, kidney and liver tissues of acutely infected catfish demonstrating active viral replication in multiple tissues during the early stages of CCV infection. However, there was no evidence for viral replication by 24 days post-infection in tissues of fish that survived the acute disease. Viral latency-associated transcripts encoded by CCV direct repeat genes were not detected in latently infected catfish. The results of this study provide a foundation for further studies to investigate the molecular basis of CCV pathogenesis and latency.

Abstract
Sediments were collected from a stream (upstream, outfall and downstream) receiving copper laden catfish pond effluent to assess toxicity to non-target biota. No significant reduction in Hyalella azteca survival or growth (10 d), or Typha latifolia germination and root and shoot growth (7 d) were observed after exposure to upstream and outfall sediments. A significant reduction in H. azteca survival was observed after exposure to the downstream sediment sample; however, no reduction in T. latifolia germination or seedling growth was detected. Bulk sediment copper concentrations in the upstream, outfall and downstream samples were 29, 31, and 25 mg Cu/kg dry weight, respectively. Interstitial water (IW) concentrations ranged from 0.053 to 0.14 mg Cu/l with 10 d IW toxicity units > or = 0.7. Outfall samples were amended with additional concentrations of copper sulfate so that bulk sediment measured concentrations in the amended samples were 172, 663, 1245, and 1515 mg Cu/kg dry weight. Survival was the most sensitive endpoint examined with respect to H. azteca with a no observed effects concentration (NOEC) and lowest observed effects concentration (LOEC) of 1245 and 1515 mg Cu/kg, respectively. NOEC and LOEC for T. latifolia root growth were 663 and 1245 mg Cu/kg, respectively. IW copper concentrations were > or = 0.86 mg Cu/l with H. azteca intersitial water toxicity unit (IWTU) concentrations > or = 1.2. Sequential extraction qualitatively revealed the carbonate and iron oxide fractions which accounted for a majority of the copper binding. In this instance, the copper which was applied to catfish ponds does not appear to be adversely impacting the receiving stream system.

Abstract
Potassium permanganate is an oxidant heavily used in fish culture. The effects of this compound were examined utilizing molecular (Metallothionein) and whole animal endpoints following an 8-week exposure to nominal concentrations of 0.5 (daily) and 1.0 and 2.0 mg/L (on alternate days) of potassium permanganate (PM). In order to measure MT, a complementary DNA clone of metallothionein (MT) was cloned and sequenced from the liver of channel catfish treated with a single injection of cadmium chloride (10 mg/kg). The cDNA was obtained by reverse transcriptase polymerase chain reaction (RT-PCR), using 3' rapid amplification of cDNA ends (RACE) technique. No significant correlation was observed with gill MT expression or sublethal endpoints indicative of toxicity (weight, length, condition index [CI], or liver somatic index [LSI). MT mRNA expression in gill was significantly reduced only after 8 weeks in the 2.0 mg/L treatment. Decreases in CI were observed in males at all time points after 4 weeks, at the 2.0 mg/L treatment concentration, with a NOEC of 1 mg/L. Reductions in LSI that were not dose dependent were also observed in both males and females throughout the 8-week study and no consistent reduction in weight gain or length was observed. These data demonstrate that minimal changes in sublethal effects occur in fish following 0.5-2.0 mg/L PM treatment after 4 weeks, but recovery from adverse effects is observed by 8 weeks, suggesting that acute (typically less than 1 week) treatment of channel catfish with PM would not significantly affect fish health.

Abstract
Channel catfish virus (CCV) disease is an acute haemorrhagic disease in juvenile channel catfish (Ictalurus punctatus). While fish that survive primary CCV infection are suspected of being carriers of CCV, little is known concerning CCV latency. In this report, fingerling catfish were infected with CCV by experimental immersion challenge. Infected fish displayed clinical signs of CCV disease, but 22% of infected fish survived the acute disease. At 140 days post-infection, PCR analysis detected CCV DNA in the blood, brain, intestines, kidney, liver and peripheral blood leukocytes of latently infected fish. Further analysis indicated the CCV genome may exist as circular or concatemeric DNA during virus latency. This study, employing an experimental model of CCV disease, confirms that CCV establishes a latent infection of channel catfish.

Abstract
UNLABELLED Recent studies suggest that preoperative induction chemotherapy +/- radiotherapy can improve the historically poor resectability and survival of patients with stage IIIA non-small-cell lung cancer, but sometimes with significant associated morbidity and mortality. Such treatment has not been studied in stage IIIB non-small-cell lung cancer, usually considered unresectable. This multiinstitutional phase II trial tested the feasibility of concurrent preoperative chemoradiotherapy for stages IIIA and IIIB non-small-cell lung cancer. METHODS Eligible patients had pathologically documented T1-4 N2-3 disease (without pleural effusions). Induction therapy was cisplatin, 50 mg/m2, days 1, 8, 29, and 36 plus VP-16, 50 mg/m2, days 1 to 5, and 29 to 33 plus concurrent radiotherapy (4500 cGy, 180 cGy fractions). Resection was attempted 3 to 5 weeks after induction if the response was stable, partial, or complete. Complete nodal mapping at thoracotomy was required. RESULTS One hundred forty-six patients were entered. This interim analysis is based on the first 75 eligible patients for whom complete surgical data are available. There were 49 men and 26 women, median age 58 years (range 32 to 75 years). Sixty-eight of (91%) patients were eligible for operation, and 63 of 75 patients (84%) underwent thoracotomy. Fifty five of 75 patients (73%), including 12 of 16 with a stable response, had a complete resection. Four of 63 patients died postoperatively (6%). Approximately one third required a "complex" resection, for example, lobectomy plus chest wall or spine resection, but mean operating time was 3.2 hours and mean blood loss was less than 1000 ml for both stages IIIA and IIIB. Complete pathology data are currently available from 53 patients: 11 (21%) had no residual tumor; 20 (30%) had rare microscopic foci of residual cancer. The 2-year survival is 40% for both stages IIIA and IIIB. CONCLUSIONS This combined modality therapy has been well tolerated and has been associated with high response and resectability rates in both stage IIIA and stage IIIB non-small-cell lung cancer. Current survival is significantly better than survivorship among historical control patients and provides a firm basis for subsequent phase III clinical trials.

Abstract
Fifty-three patients with locally advanced salivary gland malignant neoplasm were treated with fast neutron radiation therapy. All patients received treatment for gross inoperable, residual unresectable, or recurrent disease--clinical situations in which results using photon irradiation were suboptimal. With a median follow-up of 42 months and a minimum follow-up of 1 year, locoregional tumor control in the treatment field was achieved in 92% (48 of 52) of patients. An additional eight patients had regional failures outside the treatment field, resulting in an overall locoregional tumor control rate of 77% (40 of 52). The 5-year actuarial locoregional control rates were 65% overall and 75% in patients with node-positive disease. Grouping patients according to prior treatment status, actuarial 5-year locoregional control rates were 92% for patients treated definitively (without a prior surgical procedure), 63% for those treated postoperatively for gross residual disease, and 51% for those treated for recurrent disease after a surgical procedure. The P values associated with these differences were 0.12 and 0.01, respectively. There were no instances of radiation-induced facial nerve damage. This study suggests that neutron irradiation alone should be the therapy of choice in the treatment of advanced-stage salivary gland tumors and that surgery should be limited to those patients in whom disease-free margins can be obtained. The potential morbidity of a debulking surgical procedure before neutron irradiation is not warranted by an improvement in loco-regional control over that achievable with neutron therapy alone.

Abstract
Owing to their physical characteristics, electron beams are a crucial component in radiotherapy of human tumors. Besides their main indications (skin cancers, head and neck tumors, breast, chest wall recurrence, low pelvic tumors) other types and sites of malignancies are to be considered: skin lymphomas, soft tissue sarcomas, Kaposi's sarcoma in AIDS patients, as well as Intra Operative Radiotherapy.

Abstract
The records of 132 patients participating in clinical trials using fast neutron (n = 94), mixed neutron and photon (n = 16), or conventional photon (n = 22) irradiation for primary management of prostatic cancer were retrospectively reviewed to assess treatment-related neurological complications. With a median follow-up of 14 months (range 1 to 101 months), 31/132 patients (26 neutron, 3 mixed beam, 2 photon) have experienced either sciatica beginning during or shortly after treatment, or diminished bladder or bowel continence that developed at a median time of 6.5 months following treatment. Sciatica responded to oral steroids and was usually self-limited, whereas sphincter dysfunction appears to be permanent. Pre-treatment risk factors for complications included a history of hypertension, diabetes, cigarette smoking or peripheral vascular disease, with 81% of affected patients having one or more risk factors compared with 55% of unaffected patients (p = 0.01). Seven patients have moderate (5) or severe (2) residual problems, all in the cohorts receiving neutrons (6/7) or mixed beam therapy (1/7).

Abstract
Lung cancer is the most common malignant disease in the United States. Only the few tumors detected very early are curable, but there has been some progress in the management of more advanced non-small cell lung cancer, particularly in regionally inoperable disease. Prevention of central nervous system relapse is an important issue in this group of patients because brain metastases ultimately develop in 20% to 25% of them. Seventy-three patients with regionally advanced non-small cell lung cancer were entered into a Phase II trial of neutron chest radiotherapy sandwiched between four cycles of chemotherapy including cisplatin, vinblastine, and mitomycin C. Prophylactic cranial irradiation was administered concurrently with chest radiotherapy (3000 cGy in 10 fractions in 15 patients; 3600 cGy in 18 fractions in the remaining 50 patients). Patients underwent computed tomographic scan of the brain before treatment and every 3 months after treatment. The initial overall response rate was 79%, but 65 of the 73 patients have subsequently died of recurrent disease. Median follow-up is 9 months for all 73 patients and 26 months for eight long-term survivors. No patient who completed the prophylactic cranial irradiation program had clinical or radiologic brain metastases. Toxic reactions to prophylactic cranial irradiation included reversible alopecia in all patients, progressive dementia in one patient, and possible optic neuritis in one patient. Both of these patients received 300 cGy per fraction of irradiation. The use of prophylactic cranial irradiation has been controversial, but its safety and efficacy in this trial supports its application in a group of patients at high risk for central nervous system relapse. Further evaluation of prophylactic cranial irradiation in clinical trials for regionally advanced non-small cell lung cancer is warranted.

Abstract
Patients with extensive small-cell lung cancer were given induction chemotherapy consisting of cyclophosphamide, vincristine, cisplatin, and etoposide (COPE) every 3 weeks for four cycles. Responding patients then received chest and elective whole-brain irradiation. Patients presenting with brain metastases received therapeutic brain irradiation during the first cycle of chemotherapy. No maintenance therapy was given, but two late intensification cycles of COPE were given at weeks 24 and 48. Among the 34 evaluable patients, the response rate to induction chemotherapy was 59%, with 10% achieving a complete response (CR) and 49%, a partial response (PR). Of the 18 patients who completed chest irradiation, 3 achieved a CR, producing an overall CR rate of 18%. Five patients completed the projected course of treatment. The median duration of response for all patients was 8 months (range, 2-30+ months) and the median survival was 9 months (range, 1-30+ months). Complete responders had a median response duration of 9 months and a median survival of 11 months. This regimen produced significant myelosuppression, with 5 neutropenic deaths (13%) occurring in the 38 patients evaluable for toxicity; an additional 16% required hospitalization for fever while neutropenic. Only six patients (13%) had nadir platelet counts of less than 50,000/mm3 with no episodes of thrombocytopenic hemorrhage. Nausea, vomiting, and neurotoxicity were mild to moderate in all patients. One patient with no evidence of disease died of radiation pneumonitis at 6 months. While producing significant toxicity, this regimen did not result in a CR rate or survival advantage that would suggest its superiority over standard regimens for small-cell lung cancer.

Abstract
The basic radiobiological rationale for the use of fast neutron radiotherapy in the treatment of classically radioresistant tumors such as soft tissue sarcomas, osteogenic sarcomas, and chondrosarcomas is reviewed. There are no definitive randomized studies comparing high and low linear energy transfer radiotherapy for these tumor systems, but a review of published series is highly suggestive of a therapeutic advantage for fast neutrons. For soft tissue sarcomas, the local control rate is 53% (158 of 297) with fast neutrons, compared with 38% (49 of 128) with photons/electrons; for osteogenic sarcomas, the local control rate is 55% (40 of 73) with fast neutrons, compared with 21% (15 of 73) with photons/electrons; and for chondrosarcomas, the local control rate is 49% (25 of 51) with fast neutrons, compared with 33% (10 of 30) with photons/electrons. An ongoing clinical trial for these tumors is also described.

Abstract
Over 200 patients have been entered in five studies investigating the use of fast neutron radiation therapy in the treatment of non-small-cell carcinomas of the lung since 1983. The results of these studies have been inconsistent. Most studies did not show survival rates or local control advantages over standard photon radiation therapy. Side effects from studies employing mixed photon-neutron treatment plans or clinically oriented, high-energy cyclotrons were seen to be comparable to those of standard courses of radiation therapy, representing a considerable improvement over those studies utilizing low-energy cyclotrons for a full course of radiation therapy, which resulted in unacceptably high complication rates. A new phase III study utilizing high-energy isocentric neutron beams has been designed and implemented, and over 100 patients have been entered to date. The current status of fast neutron radiation therapy in the treatment of non-small-cell lung cancer is reviewed.

Abstract
Neutron radiotherapy has been used for patients with malignant gliomas for over a decade; a substantial number of patients have been treated to date. Pathologic analysis of surgical specimens posttreatment and autopsy specimens have documented an increased antitumor effect of neutrons against malignant gliomas, compared with photon irradiation. However, results of neutron trials to date have not shown a survival advantage over conventional radiotherapy for these patients. This article reviews current surgical, radiotherapeutic, and chemotherapeutic approaches to these tumors, the rationale for neutron treatment, and the results of trials of neutron radiotherapy conducted to date for patients with malignant gliomas.

Abstract
To identify possible soft-tissue changes of the head and neck after radiation therapy, 102 CT scans from 78 patients with head and neck tumors were reviewed to assess (1) skin thickening, (2) epiglottic thickening, (3) stranding of subcutaneous fat, and (4) stranding of deep cervical fat. Scans were obtained after radiation therapy alone (10 cases), after radiation and surgery (27 cases), after surgery alone (24 cases), or before either surgery or radiation (41 cases). Skin thickening, epiglottic thickening, and stranding of subcutaneous fat were seen more frequently after radiation therapy than before such treatment. However, skin thickening and stranding of subcutaneous fat were sometimes also associated with tumor involvement and/or previous surgery, while epiglottic thickening was only occasionally associated with tumor involvement. Stranding of deep cervical fat was noted with increased frequency after radiation or surgery, but postradiation effects could not be reliably distinguished from postsurgical or tumor effects. We conclude that soft-tissue changes of the head and neck on CT may commonly be associated with previous radiation therapy, but these postradiation effects are not always distinguishable from postsurgical effects or tumor.

Abstract
A total of 17 patients with superficial transitional cell carcinoma of the bladder underwent treatment with pelvic external beam irradiation followed by an intracavitary 137cesium implant via a triple lumen Foley catheter. Of these patients 11 had recurrent and multifocal superficial cancer, with 8 having relapse after prior intravesical chemotherapy. External beam doses of 3,600 to 5,066 cGy. were followed by implant doses delivering 2,000 to 3,200 cGy. to the bladder mucosa, with the sum of external and intracavitary doses totaling 6,500 to 7,500 cGy. Of 15 patients evaluable with a median followup of 48 months, and including 13 followed for more than 2 years, 11 (73 per cent) remain free of disease, 3 (20 per cent) have recurrence in the bladder but have retained the bladder and only 1 has required cystectomy. All 4 failures occurred in the subgroup of 8 patients who had received prior intravesical chemotherapy. This bladder-sparing approach is well tolerated, is an alternative to cystectomy in patients with recurrent superficial transitional cell carcinoma of the bladder and in our series has salvaged 50 per cent (4 of 8) of the patients even after failure of intravesical chemotherapy.

Abstract
Primary intramedullary spinal cord tumors are frequently difficult to localize for radiation treatment planning. Conventional imaging techniques, including unenhanced magnetic resonance (MR) scans, cannot clearly distinguish residual tumor from surrounding normal spinal cord. Recently, contrast agents have been developed for MR that have considerable promise for improving tumor volume definition. This report describes the impact of contrast-enhanced MR on the treatment planning process for four patients with primary spinal cord tumors and discusses the significance of this technique for patients with these neoplasms.

Abstract
Ependymomas of the posterior fossa extend into the upper cervical spinal cord in approximately one-third of cases. Unfortunately, the posterior fossa and upper cervical cord region is often poorly seen on computed tomography (CT), making radiotherapy planning difficult. We report five cases of posterior fossa ependymoma with extension into the cervical cord where magnetic resonance imaging (MRI) demonstrated the caudal extent of tumor more clearly than CT. The extent of tumor depicted by MRI in each case correlated well with the operative findings. Higher doses of radiotherapy to the entire tumor volume are associated with improved survival in infratentorial ependymoma; however, the radiation tolerance of the cervical spinal cord is close to the dose necessary to control posterior fossa ependymoma, making limitation of radiation field volumes important. MRI may provide a method of precisely defining caudal tumor extent of posterior fossa ependymomas so that limited volume, high dose radiotherapy can be more safely administered to these patients.

Abstract
Seventy-three patients with biopsy-proven limited non-small cell lung cancer (NSCLC) were entered on a combined modality study at the University of Washington. Seventy-five percent (55 of 73) of the patients had a histologic diagnosis of adenocarcinoma or large cell carcinoma, whereas 25% (18 of 73) had squamous cell carcinoma. After two cycles of chemotherapy, patients without evidence of progressive disease received prophylactic cranial irradiation (PCI) and chest radiotherapy, followed by two additional cycles of chemotherapy. Brain computed tomography (CT) scans were performed at 3-month intervals after completion of therapy in all patients, and were additionally performed whenever signs or symptoms developed suggesting neurologic dysfunction or recurrent brain disease. Sixty-five patients were treated with PCI. No clinical or CT evidence of recurrence in the brain has developed in patients who completed PCI. PCI appears to be effective in greatly reducing the incidence of brain relapse in patients with limited NSCLC.

Abstract
From September 1980 through January 1985, the Radiation Therapy Oncology Group (RTOG) conducted a randomized, dose-searching study testing the efficacy of a concomitant neutron boost along with whole brain photon irradiation in the treatment of malignant gliomas of the brain. Patients had to have biopsy-proven, supratentorial, anaplastic astrocytoma or glioblastoma multiforme (Nelson schema) to be eligible for the study. The whole brain photon irradiation was given at 1.5 Gy per treatment, 5 days-a-week to a total dose of 45 Gy. Two days-a-week the patients were to receive neutron boost irradiation to the tumor volume as determined on CT scans. The neutron irradiation was to be given prior to and within 3 hours of the photon irradiation on that day. The rationale for this particular treatment regime is discussed. A total of 190 evaluable patients were randomized among 6 different neutron dose levels: 3.6, 4.2, 4.8, 5.2, 5.6 and 6.0 Gyn gamma. There was no difference in overall survival among the 6 different dose levels, but for patients having less aggressive tumor histology (anaplastic astrocytoma), there was a suggestion that patients on the higher dose levels had poorer overall survival than patients on the lower dose levels and also did worse than historical photon controls. Important prognostic factors were identified using a Cox stepwise regression analysis. Tumor histology, Karnofsky performance status, and patient age were found to be related to survival while extent of surgery and neutron dose had no significant impact. Autopsies were performed on 35 patients and the results correlated with the actual neutron dose as determined by central-axis isodose calculations. At all dose levels there were some patients with both radiation damage to normal brain tissue and evidence of viable tumor. No evidence was found for a therapeutic window using this particular treatment regimen.

Abstract
Thirty-two patients with inoperable, recurrent, or gross residual malignant salivary gland tumors received fast neutron radiotherapy at the University of Washington. Eleven patients were treated with low energy neutrons alone, four received a combined photon-low energy neutron treatment regimen ("mixed beam"), and 17 were treated with high energy neutrons alone. Patients treated for microscopic residual tumor after a surgical resection were excluded from this study. With a minimum follow-up period of one year, (maximum 12 years), the overall locoregional tumor control rate for the entire series was 81%. The 5-year locoregional tumor control rate was 69%. The overall 5-year survival rate was 33% (50% for T3 tumors and 0% for T4 tumors). Compared to results obtained with conventional photon and/or electron treatment for advanced salivary gland tumors, fast neutron radiotherapy appears to offer a significant advantage.

Abstract
Fourteen patients with transitional cell carcinoma of the urinary bladder were treated with 4,000 cGy of pelvic irradiation concurrent with two 96-hour infusions of 5-fluorouracil (5-FU). Three weeks after completion of this regimen, patients underwent repeat cystoscopy and deep-muscle biopsy at the site of their original neoplasms. Eight of 14 (57%) had no tumor left in the biopsy specimen, and they received an additional course of chemotherapy and radiation therapy to a total dose of 4,400 cGy to the pelvis and 6,000 cGy to the bladder. Five of the 14 had residual tumor in the biopsy specimen (one did not undergo biopsy) and went on to planned cystectomy. Two of the five had no tumor in the cystectomy specimen. Overall, ten of the 14 patients (71%) have been downstaged to a condition of P0 (no tumor) following 4,000 cGy and two courses of 5-FU. Of eight patients with retained bladders, seven remain well at a median follow-up of 7 months. At a range of follow-up of 3-21 months and a median of 7 months, 13 of 14 patients remain tumor-free. This regimen results in a greater percentage of downstaging than conventional irradiation alone, and may allow bladder preservation for those with radiation therapy- and chemotherapy-responsive tumors.

Abstract
Sixty-nine chest CT studies of 36 patients with lung cancer were obtained at various times (21 to 649 days) following completion of fast neutron radiotherapy. Multiple scans (2 to 7) were available in 16 cases. Fractionated neutron radiotherapy was delivered over four to seven weeks to a total dose of 60 to 67 Gy photon equivalent. Parenchymal change within the lung was noted in 43% by 12 weeks, in 91% between 12 and 24 weeks, and in 100% after 24 weeks. Three different patterns of lung parenchymal change were evident. Ectatic air-filled bronchi were observed in more than 50% after 24 weeks. Mediastinal shift and thoracic shrinkage were demonstrated in six and three cases, respectively. Serial CT scans revealed that lung parenchymal changes usually became stable or shrunk after 36 weeks. The possible effect of chemotherapy (mitomycin-C, vinblastin and cis-platinum), in 19 of these patients is also discussed.
