RESUMEN
BACKGROUND: Appendicitis is the commonest paediatric surgical emergency. Adult studies suggest non-operative management (NOM) may have a place in care. There have been no adequately powered randomized controlled trials in children. OBJECTIVE: to determine the safety and efficacy of NOM for paediatric simple appendicitis. METHODS: A non-inferiority randomized controlled trial was conducted comparing operative (OM) to NOM of SA in children aged five-15 years. Primary outcome was treatment success (no unplanned or unnecessary operation, or complication) at 30 days and 12 months, with a non-inferiority margin of 15%. (anzctr.org.au: ACTRN12616000788471). RESULTS: From 11 June 2016 to 30 November 2020, 222 children were randomized: 94 (42.34%) to OM and 128 (57.66%) to NOM. Non-inferiority of NOM was not demonstrated at either time point, with 45.67% of NOM patients subsequently undergoing operation. There was no significant difference in complications. CONCLUSIONS: While noninferiority was not shown, NOM was safe, with no difference in adverse outcomes between the two groups. Further research to refine the place of NOM of simple appendicitis in children is required, including nuanced patient selection, longer term evaluation, the place of choice, and the acceptability of the treatment for children and their carers.
RESUMEN
BACKGROUND: Falls are the most common hospitalized injury mechanism in children aged ≤1 years, and currently, there are no targeted prevention interventions. The prevention of falls in children of this age requires changes in the behavior of their caregivers, and theoretically informed digital behavior change interventions (DBCIs) may provide a unique mechanism for achieving effective intervention. However, user acceptance and the ability of DBCIs to effect the required changes in behavior are critical to their likelihood of success. OBJECTIVE: This study aims to evaluate a behavior theory-informed digital intervention developed following a user-centered approach for user experience, the potential for this intervention to prevent infant falls, and its impact on behavioral drivers underpinning fall risk in young children. METHODS: Parents of infants aged <1 year were recruited and asked to use the intervention for 3 months. A pre-post longitudinal design was used to examine the change in the potential to reduce the risk of falls after a 3-month exposure to the intervention. Postintervention data on behavioral drivers for fall prevention, user acceptability, and engagement with the app were also collected. Interviews were conducted to explore user experiences and identify areas for further improvement of the intervention. RESULTS: A total of 62 parents participated in the study. A statistically significant effect on the potential to reduce falls was observed after the intervention. This effect was higher for new parents. Parents agreed that the intervention targeted most of the target behavior drivers. The impact of behavior drivers and intervention on the potential for fall prevention had a positive correlation. The intervention demonstrated good levels of acceptability. Feedback from participants was mostly positive, and the primary area identified for further improvement was widening the scope of the intervention. CONCLUSIONS: This study demonstrated the promise of a newly developed digital intervention to reduce the risk of infant falls, particularly among new parents. It also showed a positive influence of the DBCI on the drivers of parental behaviors that are important for fall reduction among infants. The acceptability of the app was high, and important insights were gained from users about how to further improve the app.
RESUMEN
Burns are a common mechanism of pediatric injury worldwide and are a notable cause of disability-adjusted life-years. Burns in children represent a unique challenge, due to the differences from adults regarding physical characteristics, physiology and psychology. This retrospective cohort study examined trends of pediatric burns in New South Wales (NSW), Australia from 2010-22. It specifically focused on the changes in burn etiology and patient characteristics, body area affected, total body surface area, first aid, location and management. It also compared a 'Pre-COVID-19' and 'Peri-COVID-19' era to analyze the impact of COVID-19 on the pattern of pediatric burns, as children are at higher risk of injury during times of social disruption. The study found that burns in children continue to be concentrated in the toddler and preschooler age group and the main mechanisms of injury remain as scald and contact burns. In recent years, there has been a rising trend of friction burns, alongside a fall in flame burns and severe burns. Management of pediatric burns has also evolved, with predominant use of ambulatory care and low rates of admission and operative intervention. Trends in burn injury continue to evolve with time and over the last decade in NSW, key changes in the pattern of pediatric burns have been observed, with evolving mechanisms of injury, reduced severity of burns and a shift towards ambulatory care.
RESUMEN
INTRODUCTION: Keeping children nil by mouth until return of bowel function after intestinal anastomosis surgery is said to reduce complications. Fasting may extend up to five days, risking malnourishment and usage of parenteral nutrition. This study aims to establish the efficacy and safety of early enteral nutrition in children undergoing intestinal stoma closure. METHODOLOGY: A retrospective cohort study of children aged three months to 16 years who underwent an intestinal stoma closure between 1/1/2019 and 31/12/2021 at two tertiary paediatric hospitals was undertaken. Children fed clear fluids within 24 h (EEN) were compared to those commencing feeds later (LEN). The primary outcome was length of post-operative stay (LOS) and secondary outcomes included: time to feeds; time to stool; and complications. RESULTS: Of the 129 children that underwent a stoma closure, 69 met inclusion criteria: 35 (51 %) in the LEN group and 34 (49 %) in the EEN group. Children in the EEN group had a significantly shorter LOS (92.6 h vs 121.7 h, p = 0.0045). Early feeding was also associated with a significantly decreased time to free fluids (p < 0.001) and full enteral intake (p = 0.007). There was no significant intergroup difference in complications. CONCLUSION: Commencing feeding within 24 h of stoma closure is efficacious and safe, with clear reductions in LOS, time to full feeds and time to stool, and no increase in complications. Further research is required to extrapolate these findings to other populations. LEVEL OF EVIDENCE: III.

Over the past 20 years, the National Institutes for Health (NIH) has implemented several policies designed to improve sharing of research data, such as the NIH public access policy for publications, NIH genomic data sharing policy, and National Cancer Institute (NCI) Cancer Moonshot public access and data sharing policy. In January 2023, a new NIH data sharing policy has gone into effect, requiring researchers to submit a Data Management and Sharing Plan in proposals for NIH funding (NIH. Supplemental information to the, 2020b; NIH. Final policy for data, 2020a). These policies are based on the idea that sharing data is a key component of the scientific method, as it enables the creation of larger data repositories that can lead to research questions that may not be possible in individual studies (Alter and Gonzalez, 2018; Jwa and Poldrack, 2022), allows enhanced collaboration, and maximizes the federal investment in research. Important questions that we must consider as data sharing is expanded are to whom do benefits of data sharing accrue and to whom do benefits not accrue? In an era of growing efforts to engage diverse communities in research, we must consider the impact of data sharing for all research participants and the communities that they represent. We examine the issue of data sharing through a community-engaged research lens, informed by a long-standing partnership between community-engaged researchers and a key community health organization (Kruse et al., 2022). We contend that without effective community engagement and rich contextual knowledge, biases resulting from data sharing can remain unchecked. We provide several recommendations that would allow better community engagement related to data sharing to ensure both community and researcher understanding of the issues involved and move toward shared benefits. By identifying good models for evaluating the impact of data sharing on communities that contribute data, and then using those models systematically, we will advance the consideration of the community perspective and increase the likelihood of benefits for all.

OBJECTIVES: Hospitalisation rates for injury, including at playgrounds, have not changed in the past decade. There are nine Australian Standards specific to playgrounds. The impact (if any) of these standards on playground injury resulting in hospitalisation is unknown. METHODS: Retrospective data for patients under 18 years presenting to emergency departments and/or admitted between October 2015 and December 2019 due to an injury documented as occurring at a playground were retrieved by the Illawarra Shoalhaven Local Health District Planning, Information and Performance Department. Maintenance and Australian Standard (AS) compliance data for the 401 local playgrounds were requested from the four Local Governments in Illawarra Shoalhaven Local Health District. Descriptive statistics were used. RESULTS: A total of 548 children were treated in emergency departments and/or admitted following playground injury. There was an overall increase of 39.3% in playground injury across the study period, and expenditure rose from $43,478 in 2011 to $367,259 in 2019 (a 744.7% increase). CONCLUSIONS: Playground injury has not decreased in the Illawarra Shoalhaven. Data regarding maintenance and AS compliance are lacking. This is not unique to our region. IMPLICATIONS FOR PUBLIC HEALTH: Without a national approach to adequately resource and monitor playground injury, it is not possible to assess the impact of Australian Standards or any injury prevention program.

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.

BACKGROUND: Falls represent the most common mechanism of injury requiring hospitalization among children under 12 months, and they commonly result in traumatic brain injury. Epidemiological studies exploring infant falls demonstrate the experienced burden, but they lack contextual information vital to the development of preventive interventions. OBJECTIVE: The objective of this study was to examine contextual information for falls involving children under 12 months, using online parenting discussion forums. METHODS: Online parenting forums provide an unobtrusive rich data source for collecting detailed information about fall events. Relevant discussions related to fall incidents were identified and downloaded using site-specific Google Search queries and a programming script. A qualitative descriptive approach was used to analyze the incidents and categorize contextual information into "precursor events" and "influencing factors" for infant falls. RESULTS: We identified 461 infant fall incidents. Common fall mechanisms included falls from furniture, falls when being carried or supported by someone, falls from baby products, and falls on the same level. Across the spectrum of fall mechanisms, common precursor events were infant rolling off, infant being alone on furniture, product misuse, caretaker falling asleep while holding the infant, and caretaker tripping/slipping while carrying the infant. Common influencing factors were infant's rapid motor development, lapses in caretaker attention, and trip hazards. CONCLUSIONS: The findings define targets for interventions to prevent infant falls and suggest that the most viable intervention approach may be to target parental behavior change. Online forums can provide rich information critical for preventive interventions aimed at changing behavior.
RESUMEN
OBJECTIVE: To develop an international core outcome set (COS), a minimal collection of outcomes that should be measured and reported in all future clinical trials evaluating treatments of acute simple appendicitis in children. SUMMARY OF BACKGROUND DATA: A previous systematic review identified 115 outcomes in 60 trials and systematic reviews evaluating treatments for children with appendicitis, suggesting the need for a COS. METHODS: The development process consisted of 4 phases: (1) an updated systematic review identifying all previously reported outcomes, (2) a 2-stage international Delphi study in which parents with their children and surgeons rated these outcomes for inclusion in the COS, (3) focus groups with young people to identify missing outcomes, and (4) international expert meetings to ratify the final COS. RESULTS: The systematic review identified 129 outcomes which were mapped to 43 unique outcome terms for the Delphi survey. The first-round included 137 parents (8 countries) and 245 surgeons (10 countries), the second-round response rates were 61% and 85% respectively, with 10 outcomes emerging with consensus. After 2 young peoples' focus groups, 2 additional outcomes were added to the final COS (12): mortality, bowel obstruction, intraabdominal abscess, recurrent appendicitis, complicated appendicitis, return to baseline health, readmission, reoperation, unplanned appendectomy, adverse events related to treatment, major and minor complications. CONCLUSION: An evidence-informed COS based on international consensus, including patients and parents has been developed. This COS is recommended for all future studies evaluating treatment ofsimple appendicitis in children, to reduce heterogeneity between studies and facilitate data synthesis and evidence-based decision-making.

BACKGROUND: Falls account for approximately 50% of infant injury hospitalizations, and caretaker behavior is central to preventing infant falls. Behavior theory-informed interventions for injury prevention have been suggested, but to date, few have been reported. The potential of using smartphones for injury prevention intervention delivery is also underexploited. OBJECTIVE: This study aims to develop a behavior theory- and evidence-based as well as user-centered digital intervention as a mobile app for parents to prevent infant falls following agile development practices. METHODS: Infant falls while feeding was selected as the fall mechanism to demonstrate the approach being taken to develop this intervention. In phase 1, the Behaviour Change Wheel was used as a theoretical framework supported by a literature review to define intervention components that were then implemented as a mobile app. In phase 2, after the person-based approach, user testing through think-aloud interviews and comprehension assessments were used to refine the content and implementation of the intervention. RESULTS: The target behaviors identified in phase 1 were adequate rest for the newborn's mother and safe feeding practices defined as prepare, position, and place. From behavioral determinants and the Behaviour Change Wheel, the behavior change functions selected to achieve these target behaviors were psychological capability, social opportunity, and reflective motivation. The selected behavior change techniques aligned with these functions were providing information on health consequences, using a credible source, instruction on performing each behavior, and social support. The defined intervention was implemented in a draft Android app. In phase 2, 4 rounds of user testing were required to achieve the predefined target comprehension level. The results from the think-aloud interviews were used to refine the intervention content and app features. Overall, the results from phase 2 revealed that users found the information provided to be helpful. Features such as self-tracking and inclusion of the social and environmental aspects of falls prevention were liked by the participants. Important feedback for the successful implementation of the digital intervention was also obtained from the user testing. CONCLUSIONS: To our knowledge, this is the first study to apply the Behaviour Change Wheel to develop a digital intervention for child injury prevention. This study provides a detailed example of evidence-based development of a behavior theory-informed mobile intervention for injury prevention refined using the person-based approach.
RESUMEN
OBJECTIVE: The main objective of this study is to describe the clinical spectrum of CM-AVM syndrome as well as radiological and genetic findings. METHODS: This is a single-centre prospective observational study performed at Sydney Children's Hospital. Patients under the age of 18 years that presented to our paediatric dermatology clinic or vascular birthmark clinic between January 2015 and September 2020 with one or more geometric shaped pink/ red/ brown macule with a peripheral pallor characteristic of a high-flow vascular stain were included. Children subsequently diagnosed with other diagnosis or family members with CM-AVM syndrome were excluded. RESULTS: Sixty children were included, with two subsequently excluded. A third of patients (n = 22, 38%) presented with a single characteristic HFVS, whereas the remaining two thirds (n = 36; 62%) had multiple HFVS. In children with multiple HFVS, one notably larger HFVS was detected in the majority of children (n = 32, 88%). In 33 patients, a brain and spine MRI was performed, which detected a spine AVM in one symptomatic patient with sensorimotor deficits. No cerebral AVM or AVF was picked up in the cohort. A RASA 1 result was available for evaluation in 24, of which 16 (67%) were positive. An EPHB4 result was available in eight, two (25%) of which were positive. CONCLUSIONS: One large HFVS often accompanied by multiple small HFVS can be seen in most patients. Despite of the lack of genetic confirmation of diagnosis in single lesions, this phenotype might be of interest and warrants further investigation.

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.

INTRODUCTION: Passage of cannabis laws may impact cannabis use and the use of other substances. The suggested association is of particular concern in pregnant women where exposure to substances can cause harm to both the pregnant woman and fetus. The present study contributes to the minimal literature on factors associated with cannabis use during the preconception, prenatal, and postpartum periods including state legalization status, concurrent use of tobacco and e-cigarettes and adequacy of prenatal care. METHODS: We conducted a cross-sectional analysis using combined survey data from the 2016-2018 Pregnancy Risk Assessment Monitoring System (PRAMS) collected from 36,391 women. Logistic regression was used to estimate the impact of state-legalization, adequacy of prenatal care, and other substance use on cannabis use during the preconception, prenatal, and post-partum periods. RESULTS: In the preconception model, residence in a recreationally legal state (OR: 2.37; 95% CI, 2.04-2.75) or medically legal state (OR:3.32; 95% CI, 2.90-3.80) compared to a non-legal state was associated with higher odds of cannabis use. In the prenatal model, residence in a recreationally legal state was associated with higher odds of cannabis use (OR: 1.51; 95% CI, 1.29-1.79) whereas there was no association with residence in a medically legal state. Tobacco use including e-cigarettes and moderate prenatal alcohol use were also significantly associated with cannabis use. CONCLUSION: Recreational cannabis legalization is associated with the use of cannabis prior to, during, and after pregnancy. Renewed clinical and policy efforts may be warranted to update prenatal substance use prevention programs, educational campaigns, and provider education as cannabis legalization evolves.

The oomycete Aphanomyces astaci is an emerging infectious pathogen affecting freshwater crayfish worldwide and is responsible for one of the most severe wildlife pandemics ever reported. The pathogen has caused mass mortalities of freshwater crayfish species in Europe and Asia, and threatens other susceptible species in Madagascar, Oceania and South America. The pathogen naturally coexists with some North American crayfish species that are its chronic carriers. Presumptions that A. astaci originated in North America are based on disease outbreaks that followed translocations of North American crayfish and on the identification of the pathogen mainly in Europe. We studied A. astaci in the southeastern US, a center of freshwater crayfish diversity. In order to decipher the origin of the pathogen, we investigated (1) the distribution and haplotype diversity of A. astaci, and (2) whether there are crayfish species-specificities and/or geographical restrictions for A. astaci haplotypes. A total of 132 individuals, corresponding to 19 crayfish species and one shrimp species from 23 locations, tested positive for A. astaci. Mitochondrial rnnS and rnnL sequences indicated that A. astaci from the southeastern US exhibited the highest genetic diversity so far described for the pathogen (eight haplotypes, six of which we newly describe). Our findings that A. astaci is widely distributed and genetically diverse in the region supports the hypothesis that the pathogen originated in the southeastern US. In contrast to previous assumptions, however, the pathogen exhibited no clear species-specificity or geographical patterns.

BACKGROUND: Vascular malformations (VMs) involving the hand and forearm in children provide management challenges due to complex anatomy, indispensable functionality and developmental implications. METHODS: The institution's Vascular Registry was searched for patients with hand and arm VMs, supplemented by chart review of included patients. RESULTS: Twenty-one patients were identified, 52% male, with mean presenting age 5.2 years. Venous malformations predominated (71%), followed by lymphatic-venous (19%), lymphatic (5%) and glomuvenous (5%). Symptoms included pain (76%), swelling (71%), cosmetic concerns (81%), functional compromise (29%) and stiffness (5%). Imaging modality was ultrasound (100%), and magnetic resonance imaging (71%). Treatment included compression (62%), sclerotherapy (62%) and surgery (24%). Post-sclerotherapy ultrasounds showed complete sclerosis (25%), near complete sclerosis (58%) and partial sclerosis (17%). Post-surgery, patients reported improved cosmesis (80%), size (100%), pain (60%) and function (40%). Complications occurred in 24%, including bleeding, digital ischaemia and thrombosis. Mean follow-up was 3.4 years. CONCLUSION: Children with low-flow VMs of the hand and forearm experience significant symptoms and functional limitations. A multidisciplinary approach to management ensures optimal outcomes.

OBJECTIVE: To assess propranolol's impact on sleep when used in infants and toddlers with infantile hemangioma (80% under 6 months old). METHODS: Parents and caregivers of infants and toddlers with infantile hemangioma presenting to a tertiary pediatric hospital's dermatology clinic and assessed by their dermatologist as requiring propranolol treatment were invited to participate. All participants completed an extended version of the Brief Infant Sleep Questionnaire (BISQ) prior to propranolol treatment initiation, which acted as the control, and 5 weeks after treatment commencement. Objective data were gathered through actigraphy, which utilizes a small wristwatch-like device that measures sleep-wake patterns, for 1 week prior to initiation and again 5 weeks after commencement. BISQ responses and actigraphy values from the two time points were compared. RESULTS: 55 infants and toddlers (aged 0-2.8 years, 80% under 6 months) were included. Sleep was reported as only a minor problem by most parents 5 weeks after starting propranolol (P = .049). Subgroup analysis of 45 infants <6 months old showed no significant difference in sleep while taking propranolol. Whole cohort BISQ data analysis showed a statistically significant increase in night-time sleep (P = .024), and a decrease in the number (P = .003) and duration of daytime naps (P = .025) following commencement of propranolol. Actigraphy data completed in 10 infants showed no significant difference in sleep quality before and 5 weeks after commencing propranolol. CONCLUSION: Propranolol did not significantly impair sleep quality and pattern in our cohort of infants and toddlers with infantile hemangioma. Most parents considered the impact on sleep to be only a minor problem.

INTRODUCTION: Chronic rhinosinusitis (CRS) is common, with a Canadian prevalence of 5%, and associated with significant morbidity. Understandably, CRS impairs workplace productivity but that productivity substantially increases following surgical treatment. CRS with nasal polyps (CRSwNP), the most common type of CRS, is usually treated with a combination of medications and endoscopic sinus surgery (ESS). Historically, surgical treatment has only been performed in the operating room at a cost of about $C3500. However, recent studies have shown that a de-escalated procedure, endoscopic polypectomy performed in clinic (EPIC), can provide an improvement in patient symptoms to levels equal to those for ESS. Moreover, EPIC has additional proposed advantages including shorter recovery time, significantly lower cost to the healthcare system and shorter wait time for the patient. There is currently insufficient evidence to draw conclusions about the superiority of polypectomy or ESS for the management of CRSwNP. METHODS AND ANALYSIS: We designed a multicentre, open-label, randomised controlled trial to evaluate whether EPIC was non-inferior to the current clinical standard, ESS for the treatment of CRSwNP. The primary outcome is the Sinonasal Outcome Test-22 score measured at baseline and at 3 months after surgery. Other outcomes include peak nasal inspiratory flow, quality of life measured by the EuroQoL 5 Dimensions 5 Levels questionnaire and work impairment using the Work Productivity and Activity Impairment Questionnaire.We aim to recruit 140 patients from sites across Canada. Participants will be randomly assigned to EPIC or ESS and followed up for 3 months in clinic after the procedure. Additionally, participants will enter a 5-year long-term follow-up period. ETHICS AND DISSEMINATION: This study was approved by the Ottawa Health Sciences Network Research Ethics Board for all sites in Ontario, Canada (study number CTO0801). Sites located outside of Ontario obtained approval from their local/institutional research ethics board. TRIAL REGISTRATION NUMBER: NCT02975310.

While sampling for the Rusty Gravedigger, Lacunicambarus miltus, Taylor et al. (2011) found one or more potentially undescribed burrowing crayfish species in the genus Lacunicambarus inhabiting the area between the Pascagoula River and Mobile Bay in southern Alabama and Mississippi. Molecular analyses by Glon et al. (2018) confirmed that samples from this area were genetically distinct from other Lacunicambarus crayfishes. These findings prompted a dedicated sampling trip in January 2020. We used morphological and molecular analyses to investigate the specimens we collected and, based on our results, we describe two new crayfish species: the Lonesome Gravedigger, L. mobilensis sp. nov. and the Banded Mudbug, L. freudensteini sp. nov. Lacunicambarus mobilensis sp. nov. is sister to the Rusty Gravedigger, L. miltus, while L. freudensteini sp. nov. is sister to the Painted Devil Crayfish, L. ludovicianus. Both new species are currently known from a small number of sites in southern Alabama and Mississippi and may require conservation attention. In addition, we provide an updated key to Lacunicambarus crayfishes that includes these new species.

AIM: Falls are the most common injury mechanism of children <12 months in Australia. We aimed to determine the prevalence of hospital admission following a fall among New South Wales (NSW) infants and changes in admission rate over time. Secondary aims were to examine demographics, nature of injury and trends by age groups associated with developmental milestones and fall mechanism. METHODS: This was a retrospective, population-based study across NSW from 2002 to 2013 using the NSW Admitted Patient Data collection. Infants with recorded falls, external causes of morbidity and mortality and activity codes were assessed. Main outcome measures were absolute numbers, rates and proportions by year, age group, socio-demographics, fall mechanism, injury type, body region affected and admission outcome. RESULTS: A total of 4380 cases were identified. Numbers increased over years (342 in 2002 to 469 in 2013). Rate of admissions per 10 000 population were 40.37 in 2002 and 47.18 in 2013 (average increase 0.9% per year, P = 0.25). 76% resided in a major city, 23% resided in the least disadvantaged areas and 18% in the most disadvantaged. Falls from furniture and falls while being carried were most common. 85% suffered a head injury, 70% of which had a traumatic brain injury (TBI). There were seven deaths and one quarter of surviving infants were admitted for 2 or more days. CONCLUSIONS: Hospital admission following a fall is a long-standing problem with no improvement among infants in NSW, commonly leading to head injury and traumatic brain injury. Effective prevention interventions are needed.
