International Core Outcome Set for Acute Simple Appendicitis in Children: Results of a Systematic Review, Delphi Study, and Focus Croups With Young People.

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.

Comparative analysis of off-road vehicle crashes in children: motorcycles versus quad bikes.

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.

Factors Associated With Cannabis Use During the Reproductive Cycle: A Retrospective Cross-Sectional Study of Women in States With Recreational and Medical Cannabis Legalization.

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.

Propranolol's effects on the sleep of infants with hemangiomas: A prospective pilot study.

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.

CM-AVM syndrome - A prospective observational study of unrelated paediatric cases.

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.

Paediatric off-road vehicle injury in rural and regional Australia.

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.

Hospitalised infants due to falls aged less 12 months in New South Wales from 2002 to 2013.

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.

Associations between changes in resilient coping and posttraumatic stress disorder symptoms.

The pervasive, damaging nature of posttraumatic stress disorder (PTSD) presents enormous clinical challenges. Understanding the relationship between patients' perceptions of PTSD symptoms and resilient coping strategies may prompt investigation of clinical interventions that improve adaptive, resilient coping skills. In this study, we examined whether changes in resilient coping were related to changes over time in the PTSD symptoms of intrusion and avoidance. A secondary analysis was conducted using longitudinal data from the community-based Washington State Twin Registry. Participants completed the four-item Brief Resilient Coping Scale (BRCS) and the Avoidance and Intrusion subscales of the Impact of Events Scale (IES) at two points in time that were at least 2 years apart. To limit analyses to participants reporting PTSD symptoms at baseline, an initial value of at least 1.0 on either Avoidance (n = 1,337) or Intrusion (n = 1,206) was required for inclusion in the sample. Using linear regression, we assessed associations of change in BRCS with a change in IES scores, controlling for the respective initial scores on each measure. Controlling for initial BRCS and IES-Intrusion values, we observed a small, statistically significant association between change in BRCS and change in IES-Intrusion scores (b* = -0.07; p = .003). There was no statistically significant association between change in BRCS and change in IES-Avoidance (b* < 0.01; p = .869). In this large, longitudinal sample, increases in resilient coping were related to decreases in intrusive thoughts over time. Because coping patterns can be taught, these results warrant further investigations into adaptive coping patterns associated with diminishing PTSD symptoms.

Does an Antimicrobial Time-Out Impact the Duration of Therapy of Antimicrobials in the PICU?

OBJECTIVES: Our aim was to perform an antimicrobial time-out 48-72 hours after commencing therapy in order to achieve a decrease in days of therapy per 1,000 patient days for vancomycin, meropenem, and piperacillin/tazobactam in all PICU patients during an 8-month period. DESIGN: This is a pre- and postimplementation quality improvement study. SETTINGS: A 30-bed PICU at a tertiary children's hospital. PATIENTS: Patients less than 21 years old admitted to the PICU from July 1, 2015, until March 31, 2016, or from July 1, 2016, until March 31, 2017, who received antibiotics for greater than 48 hours were eligible for inclusion. INTERVENTION: An antimicrobial time-out was performed after 48-72 hours of antimicrobials for all patients in the PICU during postimplementation. MEASUREMENTS AND MAIN RESULTS: The primary outcome measure was days of therapy per 1,000 patient-days for three target antibiotics: vancomycin, meropenem, and piperacillin/tazobactam. Ninety-five patients meeting inclusion criteria were admitted to the PICU during the pre-time-out period and 95 patients during the post-time-out period. The cohort that underwent time-outs had lower days of therapy for vancomycin (81.3 vs 138.1; p = 0.037) and meropenem (34.7 vs 67.1; p = 0.045). Total acquisition cost was 31 % lower for piperacillin/tazobactam and vancomycin and 46% for meropenem post implementation. Time-outs led to antimicrobial duration being defined 63% of the time and deescalation or discontinuation of antimicrobials 29% of the time. CONCLUSIONS: A 48-72-hour time-out process in rounds is associated with a reduction in days of therapy for antibiotics commonly used in the PICU and may lead to more appropriate usage. The time-outs are associated with discontinuation, deescalation, or duration being defined, which are key elements of Centers for Disease Control and Prevention-recommended antimicrobial stewardship programs.

A population-based comparison of the post-operative outcomes of open and laparoscopic appendicectomy in children.

OBJECTIVE: To assess and compare the post-operative outcomes of open and laparoscopic appendicectomy in children. DESIGN: Record linkage analysis of administrative hospital (Admitted Patient Data Collection) and emergency department (Emergency Department Data Collection) data.Participants, setting: Children under 16 years of age who underwent an appendicectomy in a public or private hospital in New South Wales between January 2002 and December 2013. MAIN OUTCOME MEASURES: Association between type of appendicectomy and post-operative complications within 28 days of discharge, adjusted for patient characteristics and type of hospital. RESULTS: Of 23 961 children who underwent appendicectomy, 19 336 (81%) had uncomplicated appendicitis and 4625 (19%) had appendicitis complicated by abscess, perforation, or peritonitis. The proportion of laparoscopic appendicectomies increased from 11.8% in 2002 to 85.8% in 2013. In cases of uncomplicated appendicitis, laparoscopic appendicectomy was associated with more post-operative complications (mostly symptomatic re-admissions or emergency department presentations) than open appendicectomy (7.4% v 5.8%), but with a reduced risk of post-operative intestinal obstruction (adjusted odds ratio [aOR], 0.59; 95% CI, 0.36-0.97). For cases of complicated appendicitis, the risk of wound infections was lower for laparoscopic appendicectomy (aOR, 0.67; 95% CI, 0.50-0.90), but not the risks of intestinal obstruction (aOR, 0.97; 95% CI, 0.62-1.52) or intra-abdominal abscess (aOR, 1.06; 95% CI, 0.72-1.55). CONCLUSION: Post-appendicectomy outcomes were similar for most age groups and hospital types. Children with uncomplicated appendicitis have lower risk of post-operative bowel obstruction after laparoscopic appendicectomy than after open appendicectomy, but may be discharged before their post-operative symptoms have adequately resolved.

Helmet use in bicycles and non-motorised wheeled recreational vehicles in children.

AIM: Injuries involving non-motorised wheeled recreational vehicles (NMWRV) and bicycles are a common cause for hospitalisation in children. Studies show that helmet use whilst bicycle riding can decrease mortality and morbidity due to head injury. However, there remains an important proportion of children who are non-helmet users (NHU). This study aims to investigate helmet use and attitudes and injury patterns in children presenting with trauma after riding bicycles and other NMWRVs. METHODS: A prospective cohort study was undertaken over 8 months of children aged 0-16 years, who presented with injury secondary to bicycle or NMWRV to the emergency department of two tertiary paediatric centres. Demographics, incident, injury severity and attitudes towards helmet use were compared between helmet users and NHU. RESULTS: A total of 342 children were included - 41% (n = 139) scooter riders, 39% (n = 133) bicyclists, 18% (n = 61) skateboarders and 2% (n = 9) in-line skaters. Of those interviewed (n = 161), 58% (n = 93) wore a helmet, with children riding bicycles significantly more likely to be helmeted than NMWRV (75 vs. 48%, P = 0.01). NHU were more likely to be admitted to hospital (P = 0.05) and to sustain a major head injury (P = 0.009). The main influence on helmet use was parental rules. The biggest factor influencing non-helmet use was perceived low levels of danger. CONCLUSIONS: Despite legislation mandating this, helmet use is not universal in cyclists, particularly younger riders. Even fewer NMWRV riders use them. To promote helmet use, a multifaceted approach aimed at altering community norms and individual behaviours and attitudes is required.

Early Posthepatoportoenterostomy Predictors of Native Liver Survival in Biliary Atresia.

OBJECTIVES: Most infants with biliary atresia (BA) require liver transplantation (LT) after hepatoportoenterostomy (HPE), including those who initially clear jaundice. The aim of the present study was to identify clinical and routine laboratory factors in infants with BA post-HPE that predict native liver survival at 2 years. METHODS: A retrospective cohort study was conducted in 217 patients with BA undergoing HPE in Sydney, Australia and Toronto, Canada between January 1986 and July 2009. Univariate and multivariate logistic regression using backwards-stepwise elimination identified variables at 3 months after HPE most associated with 2-year native liver survival. RESULTS: Significant variables (P < 0.05) on univariate analysis included serum total bilirubin (TB) and albumin at 3 months post-HPE, bridging fibrosis or cirrhosis on initial liver biopsy, ascites of <3 months post-HPE, type 3 BA anatomy, age at HPE of >45 days, change in length z scores within 3 months of HPE, and center. On multivariate analysis, TB (P < 0.0001) and albumin (P = 0.02) at 3 months post-HPE, and center (P = 0.0003) were independently associated with native liver survival. Receiver operating characteristic analysis revealed an optimal cut-off value of TB <74 µmol/L (4.3 mg/dL; area under the receiver operating characteristic curve 0.8990) and serum albumin level >35 g/L (3.5 mg/dL; area under the receiver operating characteristic curve 0.7633) to predict 2-year native liver survival. TB and albumin levels 3 months post-HPE defined 3 groups (1: TB ≤74 µmol/L, albumin >35 g/L; 2: TB ≤74 µmol/L, albumin ≤35 g/L; 3: TB >74 µmol/L) with distinct short- and long-term native liver survival rates (log-rank P < 0.001). Length z scores 3 months post-HPE were poorer for group 2 than group 1 (-0.91 vs -0.30, P = 0.0217) with similar rates of coagulopathy. CONCLUSIONS: Serum TB and albumin levels 3 months post-HPE independently predicted native liver survival in BA when controlling for center. Serum albumin level <35 g/L in infants with BA who were no longer jaundiced at 3 months post-HPE was a poor prognostic indicator. Poorer linear growth and absence of significant coagulopathy suggest a role for early aggressive nutritional therapy in this group.

Paediatric injury from indoor trampoline centres.

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

Localised intravascular coagulation complicating venous malformations in children: Associations and therapeutic options.

Venous malformations are slow-flow congenital vascular malformations that enlarge as the child ages and may be associated with localised intravascular coagulation, a consumptive coagulopathy characterised by elevated D-dimer and decreased fibrinogen levels. The authors review the known correlations between localised intravascular coagulation and venous malformation number, size and planes involved, and call attention to the concept of the progression of localised intravascular coagulopathy as the child ages and their venous malformations enlarge. The authors also discuss the identified therapeutic options for its investigation, management and treatment, including compression garments, anti-coagulation therapy, sclerotherapy, endovascular laser, surgical excision and sirolimus (rapamycin). Evidence for protocol improvements that may be instigated for the optimal physical and medical therapy of venous malformations complicated by localised intravascular coagulopathy is reviewed.

Five lessons in uncomplicated appendicitis: Can we remove the surgery?

Appendicectomy has remained the treatment of choice for appendicitis for over a century and is the most commonly performed emergency operation in children. However, emerging evidence suggests that appendicectomy may not always be necessary in uncomplicated appendicitis, with early paediatric trials demonstrating that antibiotic-only therapy can be safe and effective. Further rigorously designed and appropriately powered studies are necessarily to establish the place of non-operative management of uncomplicated appendicitis in the future.

Injury from falls in infants under one year.

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

Paediatric lymphoedema: A retrospective chart review of 86 cases.

AIM: To define the clinical characteristics, investigations, management and outcomes of lymphoedema in a paediatric cohort. METHODS: A retrospective chart review of children with lymphoedema seen at two tertiary paediatric hospitals since 1998. Telephone interviews with parents were performed when information was missing. Information recorded included demographic data, features of diagnosis and clinical presentation, symptoms, complications and treatment. RESULTS: A total of 86 patients with lymphoedema were identified. Eighty cases (93%) were primary and six cases (7%) were secondary. Most were female (60%). Location of swelling was most commonly the lower limbs (94%). There were 13 cases (15%) of genital involvement. Swelling presented in the first 12 months of life in 60% of primary lymphoedema patients. Complications of lymphoedema occurred in 73% of patients. Lymphoscintigraphy was the most common investigation used (65%), followed by ultrasound (57%) and magnetic resonance imaging (MRI) (35%). Eight of the 48 (17%) lymphoscintigraphs produced a false negative result or were inconclusive with a correct diagnosis subsequently made clinically and using MRI. Average time to diagnosis was 9 months. Lymphoedema was managed with compression garments (99%), manual lymph drainage (97%) and multilayered bandaging (68%). Eight patients had an operative procedure as a part of management. CONCLUSIONS: Primary lymphoedema is more common than secondary lymphoedema in children. Onset tends to be during infancy for both males and females, and the lower limb is typically involved. Causes of secondary lymphoedema are diverse and rare. Diagnosis in children is often delayed but is possible based on history and physical examination alone and when further investigation is necessary MRI is effective.

Clinical significance of liver histology on outcomes in biliary atresia.

AIM: Biliary atresia (BA) literature has focussed on the relationship between age at Kasai procedure (KP) and post-KP outcomes. This study primarily examines post-KP outcomes including, 6-month normalisation of bilirubin, 5-year native liver survival (NLS), development of portal hypertension (PHT) and incidence of ascending cholangitis at a single tertiary paediatric centre in Australia. The study also evaluated prognostic factors which may influence these aforementioned outcomes. METHODS: Retrospective chart review of all BA cases between 1999 and 2014. Age at KP, liver biopsy results, use of ursodeoxycholic acid or prophylactic antibiotics and occurrence of PHT and ascending cholangitis post-KP were recorded and related to the primary post-KP outcome measures. RESULTS: BA was diagnosed in 29 patients. Twenty-four of 29 patients underwent KP. Median age at KP was 68 days (29-104). Fourteen of 24 (58.3%) had bridging fibrosis and 5 of 24 (20.8%) had cirrhosis at time of KP. Median follow-up was 8.4 years (2.08-15.58 years). Bilirubin normalisation within 6 months occurred in 7 of 24 (29.2%) patients and 5-year NLS was 45.8% (11/24). Fourteen of 24 (58.3%) had PHT and 18 of 24 (75%) patients had ascending cholangitis post-KP. Absence of bridging fibrosis in liver histology at KP was the only factor to be significantly associated with improved 5-year NLS. None of the other variables examined had a significant association with either 5-year NLS or bilirubin normalisation by 6 months. CONCLUSION: Five-year NLS in this series was 45.8%. Absence of bridging fibrosis at time of KP was the only factor significantly associated with improved 5-year NLS.

Consensus statement for the treatment of infantile haemangiomas with propranolol.

Although most infantile haemangiomas do not require treatment due to a natural history of spontaneous involution, some require early intervention. The Australasian Vascular Anomalies Network and the Australasian Paediatric Dermatology Network have developed a consensus statement for the treatment of infantile haemangiomas with oral propranolol. Infants with haemangiomas that are life threatening, at risk of ulceration, or at risk of causing a significant functional impairment, psychological impact or physical deformity should be treated early with oral propranolol. Oral propranolol is safe and effective and in most healthy infants oral propranolol can be started in an outpatient setting.
