Epidemiology of Headache in Children in a Community Emergency Department: A Scoping Study.

OBJECTIVE: This study aimed to describe the epidemiology of headache in children attending a community mixed adult-pediatric emergency department (ED) in Australia with a view to providing scoping data for future headache-related projects for the pediatric ED research networks. METHODS: This is a retrospective cohort study by medical record review. Participants were children aged 2 to 16 years who presented to the ED between January 1, 2016, and December 31, 2016, with a major symptom of headache. Exclusion criteria were a history of recent head trauma, a ventriculoperitoneal shunt in situ, or known intracranial conditions associated with headache. Data collected included demographics, clinical features, investigations, diagnosis, disposition, and outcome. The primary outcomes of interest were the proportion of children with a serious ED diagnosis, the distribution of ED diagnoses, investigation ordering patterns, treatments provided, and clinical outcome. RESULTS: A total of 225 children were studied, with a median age of 9 years (interquartile range, 6-13 years). The most common associated symptoms were fever (47%) and vomiting (42%). The most common examination feature was fever (21%). Abnormal neurological findings were very uncommon. Few children underwent advanced neuroimaging (7 patients; 3%), and no intracranial abnormalities were detected. Seven children had a serious diagnosis (7/225 [3%]; 95% confidence interval, 2%-6%). Six of these 7 were viral meningitis, and there was 1 case of bacterial meningitis. CONCLUSIONS: In a community teaching hospital cohort of children with headache, intercurrent viral illness is the most common cause. Serious causes were very uncommon. The rate of bacterial meningitis, tumor, or abscess was <1%. This has implications for the planning of research projects.

Postconcussive Symptoms Following Mild TBI and Extracranial Injury: What Are the Contributing Factors?

OBJECTIVES: Whether mild traumatic brain injury (mTBI) sustained by children results in persistent or recurrent symptoms, over and above those experienced by children who solely sustain mild extracranial injuries, remains debated. The current prospective longitudinal case-controlled study aimed to examine the relative influence of injury and noninjury factors on symptoms in preschool and primary school-aged children who sustained an mTBI or mild extracranial injury at least 8 month earlier. METHODS: Participants were 64 parents of children (31 mTBI, 33 trauma controls) who sustained injury between ages 2 and 12, whose postconcussive symptoms across the first 3-month postinjury have been previously described. The current study assessed postconcussive symptoms at 8 or more months postinjury (M = 24.3, SD = 8.4) and examined a range of injury and noninjury predictive factors. RESULTS: At or beyond 8-month postinjury, symptom numbers in the mTBI group were comparable with those of the group who sustained mild extracranial injury. Educational attainment of parents (below or above high-school attainment level) was the only predictor of symptoms at follow-up, with preexisting learning difficulties approaching significance as a predictor. CONCLUSIONS: While our earlier study found that mTBI was associated with symptoms at 3-month postinjury, follow-up at more than 8 months showed mTBI no longer predicted symptom reporting. While mTBI contributes significantly to the presence of symptoms in the first few months postinjury, researchers and healthcare practitioners in this field need to consider the potential impact of noninjury factors on persistent or recurrent symptoms after mTBI.

Parent perspectives on children and young people's mental health services in Victoria - What's wrong and how to fix it: A multi-site qualitative study.

AIM: The number of children and young people presenting to emergency departments (EDs) with anxiety and depression is increasing. We aimed to determine parent perspectives on: (i) barriers to accessing non-ED mental health services; and (ii) improving access in the paediatric mental health service system. METHODS: Qualitative study with parents of children and young people aged 0-19 years who attended one of four EDs across Victoria between October 2017 and September 2018 and received a primary diagnosis of anxiety or depression. EXCLUSION CRITERIA: child or young person without a parent/guardian, or presented with self-harm or suicide attempt. Eligible participants completed semi-structured phone interviews. Interviews were recorded and transcripts were coded and analysed using content analysis. RESULTS: A total of 72 parents completed interviews. The average child age was 14 years (standard deviation 2.5) and two thirds identified as female (64%). A total of 57% of children and young people presented with a primary diagnosis of anxiety. Parents reported barriers in accessing care including: service shortages and inaccessibility, underresourced schools, lack of clinician mental health expertise, lack of child-clinician rapport, inconsistent care, financial constraints, lack of mental health awareness among parents, and stigma. Parents want expanded and improved access to services, more respite and support services, supportive schools, and improved mental health education for parents. CONCLUSIONS: Parents of children and young people attending the ED for anxiety and depression are generally dissatisfied with services for child mental health. Solutions that enable parents to better care for their child in the community are needed to improve care.

PREDICT prioritisation study: establishing the research priorities of paediatric emergency medicine physicians in Australia and New Zealand.

BACKGROUND: The Paediatric Research in Emergency Departments International Collaborative (PREDICT) performs multicentre research in Australia and New Zealand. Research priorities are difficult to determine, often relying on individual interests or prior work. OBJECTIVE: To identify the research priorities of paediatric emergency medicine (PEM) specialists working in Australia and New Zealand. METHODS: Online surveys were administered in a two-stage, modified Delphi study. Eligible participants were PEM specialists (consultants and senior advanced trainees in PEM from 14 PREDICT sites). Participants submitted up to 3 of their most important research questions (survey 1). Responses were collated and refined, then a shortlist of refined questions was returned to participants for prioritisation (survey 2). A further prioritisation exercise was carried out at a PREDICT meeting using the Hanlon Process of Prioritisation. This determined the priorities of active researchers in PEM including an emphasis on the feasibility of a research question. RESULTS: One hundred and six of 254 (42%) eligible participants responded to survey 1 and 142/245 (58%) to survey 2. One hundred and sixty-eight (66%) took part in either or both surveys. Two hundred forty-six individual research questions were submitted in survey 1. Survey 2 established a prioritised list of 35 research questions. Priority topics from both the Delphi and Hanlon process included high flow oxygenation in intubation, fluid volume resuscitation in sepsis, imaging in cervical spine injury, intravenous therapy for asthma and vasopressor use in sepsis. CONCLUSION: This prioritisation process has established a list of research questions, which will inform multicentre PEM research in Australia and New Zealand. It has also emphasised the importance of the translation of new knowledge.

Do Concussive Symptoms Really Resolve in Young Children?

OBJECTIVES: To examine the frequency and nature of postconcussive symptoms (PCSs) and behavioral outcomes in young children following mild traumatic brain injury (mTBI) or concussion. SETTING: Emergency department. PARTICIPANTS: Children aged 2 to 12 years presenting with either a concussion or minor bodily injury (control). OUTCOME MEASUREMENT: Parent ratings of PCS were obtained within 72 hours of injury, at 1 week, and 1, 2, and 3 months postinjury using a comprehensive PCS checklist. Preinjury behavior was examined at baseline using the Clinical Assessment of Behavior, which was readministered 1 and 3 months postinjury. RESULTS: PCS burden following mTBI peaked in the acute phase postinjury but reduced significantly from 1 week to 1 month postinjury. Parents of children with mTBI reported more persistent PCSs up to 3 months postinjury than trauma controls, characterized mostly by behavioral and sleep-related symptoms. Subtle increases in problematic behaviors were observed from baseline (preinjury) to 1 month postinjury and persisted at 3 months postinjury; however, scores were not classified as clinically "at risk." CONCLUSIONS: A significant minority of young children experienced persistent PCS and problematic behavior following mTBI. Care must be taken when assessing PCS in younger children as method of PCS assessment may influence parental reporting.

Influence of weather on incidence of bronchiolitis in Australia and New Zealand.

AIM: We aimed to examine the impact of weather on hospital admissions with bronchiolitis in Australia and New Zealand. METHODS: We collected data for inpatient admissions of infants aged 2-12 months to seven hospitals in four cities in Australia and New Zealand from 2009 until 2011. Correlation of hospital admissions with minimum daily temperature, wind speed, relative humidity and rainfall was examined using linear, Poisson and negative binomial regression analyses as well as general estimated equation models. To account for possible lag between exposure to weather and admission to hospital, analyses were conducted for time lags of 0-4 weeks. RESULTS: During the study period, 3876 patients were admitted to the study hospitals. Hospital admissions showed strong seasonality with peaks in wintertime, onset in autumn and offset in spring. The onset of peak incidence was preceded by a drop in temperature. Minimum temperature was inversely correlated with hospital admissions, whereas wind speed was directly correlated. These correlations were sustained for time lags of up to 4 weeks. Standardised correlation coefficients ranged from -0.14 to -0.54 for minimum temperature and from 0.18 to 0.39 for wind speed. Relative humidity and rainfall showed no correlation with hospital admissions in our study. CONCLUSION: A decrease in temperature and increasing wind speed are associated with increasing incidence of bronchiolitis hospital admissions in Australia and New Zealand.

Bell's palsy in children: Current treatment patterns in Australia and New Zealand. A PREDICT study.

AIM: The aetiology and clinical course of Bell's palsy may be different in paediatric and adult patients. There is no randomised placebo controlled trial (RCT) to show effectiveness of prednisolone for Bell's palsy in children. The aim of the study was to assess current practice in paediatric Bell's palsy in Australia and New Zealand Emergency Departments (ED) and determine the feasibility of conducting a multicentre RCT within the Paediatric Research in Emergency Departments International Collaborative (PREDICT). METHODS: A retrospective analysis of ED medical records of children less than 18 years diagnosed with Bell's palsy between 1 January, 2012 and 31 December, 2013 was performed. Potential participants were identified from ED information systems using Bell's palsy related search terms. Repeat presentations during the same illness were excluded but relapses were not. Data on presentation, diagnosis and management were entered into an online data base (REDCap). RESULTS: Three hundred and twenty-three presentations were included from 14 PREDICT sites. Mean age at presentation was 9.0 (SD 5.0) years with 184 (57.0%) females. Most (238, 73.7%) presented to ED within 72 h of symptoms, 168 (52.0%) had seen a doctor prior. In ED, 218 (67.5%) were treated with steroids. Prednisolone was usually prescribed for 9 days at around 1 mg/kg/day, with tapering in 35.7%. CONCLUSION: Treatment of Bell's palsy in children presenting to Australasian EDs is varied. Prednisolone is commonly used in Australasian EDs, despite lack of high-level paediatric evidence. The study findings confirm the feasibility of an RCT of prednisolone for Bell's palsy in children.

Acute post-concussive symptoms in young children.

OBJECTIVES: Despite peaks of mild traumatic brain injury (mTBI) incidence in young children, few studies have examined the nature of post-concussive symptoms (PCSs) in children under the age of eight, whilst controlling for pre-injury symptoms and effects of trauma. The current study aimed to identify which PCSs differentiate children with mTBI from trauma controls early post-injury, and whether these differed among preschool and school-aged children. METHODS: The sample comprised 101 children aged 2-12 presenting to an emergency department, with concussion or other minor bodily injury (control). Groups were divided by age (preschool and school-aged). PCSs were assessed within 72 hours post-injury using a comprehensive PCS checklist, administered to their parents via structured interview. RESULTS: Parents of children with mTBI reported significantly more symptoms in their children than parents of children with other minor bodily trauma, p < 0.001, r = 0.84. Parents of preschool and school-aged children reported an equal number of symptoms. However, subtle differences were observed between symptom profiles of preschool and school-aged children. CONCLUSIONS: Primary care clinicians should be aware of post-concussive symptom presentations in children of varying ages, in order to provide optimal care, especially in younger children. Methods of eliciting symptoms may influence the identification of symptoms. This issue warrants further examination in the paediatric population.

Nasogastric Hydration in Infants with Bronchiolitis Less Than 2 Months of Age.

OBJECTIVES: To determine whether nasogastric hydration can be used in infants less than 2 months of age with bronchiolitis, and characterize the adverse events profile of these infants compared with infants given intravenous (IV) fluid hydration. STUDY DESIGN: A descriptive retrospective cohort study of children with bronchiolitis under 2 months of age admitted for hydration at 3 centers over 3 bronchiolitis seasons was done. We determined type of hydration (nasogastric vs IV fluid hydration) and adverse events, intensive care unit admission, and respiratory support. RESULTS: Of 491 infants under 2 months of age admitted with bronchiolitis, 211 (43%) received nonoral hydration: 146 (69%) via nasogastric hydration and 65 (31%) via IV fluid hydration. Adverse events occurred in 27.4% (nasogastric hydration) and 23.1% (IV fluid hydration), difference of 4.3%; 95%CI (-8.2 to 16.9), P = .51. The majority of adverse events were desaturations (21.9% nasogastric hydration vs 21.5% IV fluid hydration, difference 0.4%; [-11.7 to 12.4], P = .95). There were no pulmonary aspirations in either group. Apneas and bradycardias were similar in each group. IV fluid hydration use was positively associated with intensive care unit admission (38.5% IV fluid hydration vs 19.9% nasogastric hydration; difference 18.6%, [5.1-32.1], P = .004); and use of ventilation support (27.7% IV fluid hydration vs 15.1% nasogastric hydration; difference 12.6 [0.3-23], P = .03). Fewer infants changed from nasogastric hydration to IV fluid hydration than from IV fluid hydration to nasogastric hydration (12.3% vs 47.7%; difference -35.4% [-49 to -22], P < .001). CONCLUSIONS: Nasogastric hydration can be used in the majority of young infants admitted with bronchiolitis. Nasogastric hydration and IV fluid hydration had similar rates of complications.

Predictors of Post-concussive Symptoms in Young Children: Injury versus Non-injury Related Factors.

OBJECTIVES: A notable minority of children will experience persistent post-concussive symptoms (PCS) following mild traumatic brain injury (mTBI), likely maintained by a combination of injury and non-injury related factors. Adopting a prospective longitudinal design, this study aimed to investigate the relative influence of child, family, and injury factors on both acute and persistent PCS in young children. METHODS: Participants were 101 children aged 2-12 who presented to an Emergency Department, with either mTBI or minor bodily trauma (control). PCS were assessed at time of injury, 1 week, and 1, 2, and 3 months post-injury. Predictors included injury and demographic variables, premorbid child behavior, sleep hygiene, and parental stress. Random effects ordinal logistic regression models were used to analyze the relative influence of these predictors on PCS at early (acute - 1 week) and late (1-3 month) post-injury phases. RESULTS: Presence of mTBI was a stronger predictor of PCS in the early [odds ratio (OR)=18.2] compared with late (OR=7.3) post-injury phase. Older age at injury and pre-existing learning difficulties were significant predictors of PCS beyond 1 month post-injury. Family factors, including higher levels of parental stress, higher socio-economic status, and being of Anglo-Saxon descent, consistently predicted greater PCS. CONCLUSIONS: Injury characteristics were significantly associated with PCS for 3 months following mTBI but the association weakened over time. On the other hand, pre-existing child and family factors displayed an increasingly strong association with PCS over time. Follow-up for these "at-risk" children which also addresses family stress may minimize longer-term complications. (JINS, 2016, 22, 793-803).

Paediatric procedural sedation within the emergency department.

Procedural sedation and analgesia in children requires the use of non-pharmacological and pharmacological approaches to facilitate the management of painful procedures. The development of skills in such techniques has mirrored the development of paediatric emergency medicine as a subspecialty. Governance, education and credentialing must facilitate safe sedation practice, using a structured approach, as sedating children in the busy environment of an emergency department is not without risk. Emergency clinicians, patients and caregivers all have a role to play in developing a safe, effective sedation plan.

The diagnosis and management of children presenting with anaphylaxis to a metropolitan emergency department: A 2-year retrospective case series.

AIM: To investigate the diagnosis and management of children with anaphylaxis presenting to an Emergency Department (ED). We compared the management with the Australasian Society of Clinical Immunology and Allergy (ASCIA) guidelines to gauge compliance. METHODS: A retrospective case series was developed from children aged from birth to 16 years presenting to the ED at Sunshine Hospital (SH) in Melbourne, Australia over a 2-year period from 1 January 2012 to 31 December 2013. The demographic characteristics, causative agents, clinical features, treatment administered and discharge destination were recorded. RESULTS: Fifty-five children diagnosed with anaphylaxis during the 2-year period were identified. Fifty-two children (95%) met the ASCIA diagnostic criteria, 49 (94%) children received adrenaline. The median age of presentation was five years, with males predominating (32 (62%)). The most common setting was home (35 (67%)), and food (39 (75%)) was the most common causative agent. Cutaneous symptoms (50 (96%)) were the most prevalent. Twenty-eight (54%) children received adrenaline prior to arrival in ED, whilst 22 (42%) received adrenaline in the ED. Thirty-three (63%) children were discharged home. CONCLUSION: Childhood anaphylaxis commonly presents to the ED. More than half of children presenting with anaphylaxis were treated prior to attending the ED. The findings demonstrate that anaphylaxis diagnosis and management guidelines are being adhered to in the majority of cases. There were no adverse outcomes recorded.

Complementary and alternative medicine use among paediatric emergency department patients.

AIM: To determine the period prevalence and nature of complementary and alternative medicine (CAM) use among paediatric emergency department (ED) patients and the perceptions of CAM among the CAM administrators. METHODS: A survey was undertaken in four Victorian EDs (January to September 2013). A convenience sample of parents/carers accompanying paediatric patients completed a self-administered questionnaire. The main outcome measures were CAM use and perceptions of CAM. RESULTS: The parents/carers of 883 patients participated. Three hundred eighty-eight (43.9%, 95% confidence interval (CI) 40.6-47.3) and 53 (6.0%, 95% CI 4.6-7.8) patients had taken a CAM within the previous 12 months and on the day of presentation, respectively. There were no gender differences between CAM users and non-users (P = 0.83). The use of CAM was significantly more common among older patients (P < 0.001), those with European ethnicity (P = 0.046) and among those with chronic disease (P < 0.01). Fish oil, garlic, chamomile and acidophilus were the most commonly used CAM. Only 4.4% of CAM use was reported to the ED doctor. There were reports of potentially dangerous CAM use (St John's wort, ginseng). Parents/carers who had administered CAM were more likely to report that CAMs are safe, drug free and could prevent illness (P < 0.01). In addition, a number of this group reported that CAMs are more effective than prescription medicines and safe when taken with prescription medicines. CONCLUSION: CAM use is common among paediatric ED patients although rarely reported to the ED doctor. Parents/carers who administer CAM have differing perceptions of CAM safety from those who do not.

Changes in saccadic eye movement and memory function after mild closed head injury in children.

AIM: The aim of this study was to determine whether volitional saccadic impairments are present in children with mild closed head injury (mCHI) and whether these deficits are predictive of ongoing cognitive impairment. METHOD: We analysed a sample of 26 children with mCHI (20 males, 6 females; mean age 13y 1mo, SD 2y) and 29 age-matched comparison children (20 males, 9 females; mean age 12y 2mo, SD 2y). Participants completed a battery of saccadic eye movement tasks and a set of computer-based cognitive tasks at three time points: within 2 weeks of mCHI, and at 3 months and 6 months. RESULTS: The group with mCHI made fewer errors on the antisaccade task at the first time point and showed increased latencies on prosaccades, correct antisaccades, and corrected antisaccade errors at the third time point (6mo). The group with mCHI also showed poorer performance on the cognitive tasks assessing memory. INTERPRETATION: Even very mild, uncomplicated mCHI in children may persistently affect aspects of executive control and visual processing.

Unusual presentation of acute otomastoiditis with petrositis.

The anatomical relationships of the middle ear, the mastoid air cells, the temporal bone and intracranial structures can lead to invasive infections. Acute mastoiditis is the most common intratemporal complication of acute otitis media. Timely management includes antimicrobial therapy, imaging including ultrasound and/or computed tomography, surgical consultation and intervention. There are insufficient data to provide an evidence-based diagnostic tool for acute mastoiditis. Clinical, laboratory and microbiological differences between children with simple and complicated mastoiditis will be explored after case presentation of a 5-year-old boy with fever and a tender, soft-tissue swelling over the left zygomatic arch.

Outcome of reduction of paediatric forearm fracture by emergency department clinicians.

OBJECTIVES: Paediatric forearm fractures are common. Anecdotally, there is a trend towards ED reduction of selected fractures under procedural sedation. We aimed to determine the rate of subsequent operative intervention for fracture re-displacement. METHODS: Retrospective observational study of children with a forearm/wrist fracture undergoing fracture reduction in ED. Outcome of interest was operative intervention for fracture re-displacement within 6 weeks. RESULTS: Among 176 patients studied, operative intervention occurred in nine patients (5.1%, 95% confidence interval 2.7-9.4%). CONCLUSION: Reduction of paediatric forearm fractures under procedural sedation by ED clinicians is increasingly common and results in a low rate of subsequent operative intervention.

Mid-Arm Point in PAEDiatrics (MAPPAED): An effective procedural aid for safe pleural decompression in trauma.

OBJECTIVE: Life-threatening thoracic trauma requires emergency pleural decompression and thoracostomy and chest drain insertion are core trauma procedures. Reliably determining a safe site for pleural decompression in children can be challenging. We assessed whether the Mid-Arm Point (MAP) technique, a procedural aid proposed for use with injured adults, would also identify a safe site for pleural decompression in children. METHODS: Children (0-18 years) attending four EDs were prospectively recruited. The MAP technique was performed, and chest wall skin marked bilaterally at the level of the MAP; no pleural decompression was performed. Radio-opaque markers were placed over the MAP-determined skin marks and corresponding intercostal space (ICS) reported using chest X-ray. RESULTS: A total of 392 children participated, and 712 markers sited using the MAP technique were analysed. Eighty-three percentage of markers were sited within the 'safe zone' for pleural decompression (4th to 6th ICSs). When sited outside the 'safe zone', MAP-determined markers were typically too caudal. However, if the site for pleural decompression was transposed one ICS cranially in children ≥4 years, the MAP technique performance improved significantly with 91% within the 'safe zone'. CONCLUSIONS: The MAP technique reliably determines a safe site for pleural decompression in children, albeit with an age-based adjustment, the Mid-Arm Point in PAEDiatrics (MAPPAED) rule: 'in children aged ≥4 years, use the MAP and go up one ICS to hit the safe zone. In children <4 years, use the MAP.' When together with this rule, the MAP technique will identify a site within the 'safe zone' in 9 out of 10 children.

Inborn Errors of Immunity in Children With Invasive Pneumococcal Disease: A Multicenter Prospective Study.

BACKGROUND: In settings with universal conjugate pneumococcal vaccination, invasive pneumococcal disease (IPD) can be a marker of an underlying inborn error of immunity. The aim of this study was to determine the prevalence and characterize the types of immunodeficiencies in children presenting with IPD. METHODS: Multicenter prospective audit following the introduction of routinely recommended immunological screening in children presenting with IPD. The minimum immunological evaluation comprised a full blood examination and film, serum immunoglobulins (IgG, IgA and IgM), complement levels and function. Included participants were children in whom Streptococcus pneumoniae was isolated from a normally sterile site (cerebrospinal fluid, pleura, peritoneum and synovium). If isolated from blood, features of sepsis needed to be present. Children with predisposing factors for IPD (nephrotic syndrome, anatomical defect or malignancy) were excluded. RESULTS: Overall, there were 379 episodes of IPD of which 313 (83%) were eligible for inclusion and 143/313 (46%) had an immunologic evaluation. Of these, 17/143 (12%) were diagnosed with a clinically significant abnormality: hypogammaglobulinemia (n = 4), IgA deficiency (n = 3), common variable immunodeficiency (n = 2), asplenia (n = 2), specific antibody deficiency (n = 2), incontinentia pigmenti with immunologic dysfunction (n = 1), alternative complement deficiency (n = 1), complement factor H deficiency (n = 1) and congenital disorder of glycosylation (n = 1). The number needed to investigate to identify 1 child presenting with IPD with an immunologic abnormality was 7 for children under 2 years and 9 for those 2 years old and over. CONCLUSIONS: This study supports the routine immune evaluation of children presenting with IPD of any age, with consideration of referral to a pediatric immunologist.

Chlorhexidine skin cleaning to reduce clean-catch urine contamination in infants: A pilot study.

OBJECTIVE: Clean-catch urine (CCU) samples are frequently contaminated. Our aim was to determine if cleaning with 0.1% chlorhexidine before CCU is a safe and feasible method to reduce contamination. METHODS: Prospective interventional pilot study. Children 1-24 months underwent perigenital skin cleaning with 0.1% chlorhexidine. Primary outcome was contamination rate, and secondary outcomes were parent and clinician satisfaction with the procedure. RESULTS: Twelve of 54 urine samples were contaminated (22%, 95% CI 13-35). Over 90% of parents and clinicians were either 'satisfied' or 'very satisfied'. No adverse events were recorded. CONCLUSION: Cleaning with chlorhexidine solution before CCU is safe and feasible.
