RESUMEN
AIM: To establish the burden of respiratory illness in cerebral palsy (CP) on the Western Australian health care system by quantifying the costs of respiratory hospitalizations in children with CP, compared with non-respiratory hospitalizations. METHOD: A 2-year (2014-2015) retrospective study using linked hospital data (excluding emergency department visits), in a population of children with CP in Western Australia aged 18 years and under (median age at hospitalization 7 years; interquartile range 5-12 years). RESULTS: In 671 individuals (57% male) there were 726 emergency hospitalizations, and 1631 elective hospitalizations. Although there were more elective hospitalizations, emergency hospitalizations were associated with longer stays in hospital, and more days in an intensive care unit, resulting in a higher total cost of emergency hospitalizations than elective hospitalizations (total costs: emergency AU$7 748 718 vs elective AU$6 738 187). 'Respiratory' was the leading cause of emergency hospitalizations, contributing to 36% of all emergency admission costs. For a group of high-cost inpatient users (top 5% of individuals with the highest total inpatient costs) the most common reason for hospitalization was 'respiratory'. Where non-respiratory admissions were complicated by an additional respiratory diagnosis, length of stay was greater. INTERPRETATION: Respiratory hospitalizations in CP are a significant driver of health care costs. In the paediatric group, they are a burden for a subgroup of children with CP. WHAT THIS PAPER ADDS: Respiratory illness is the most costly area for unplanned, emergency hospitalizations for children and young people with cerebral palsy. The top 5% of individuals with the highest total inpatient costs account for a disproportionate amount of health care costs.

Objective: Early and accurate recognition of asthma exacerbations reduces the duration and risk of hospitalization. Current diagnostic methods depend upon patient recognition of symptoms, expert clinical examination, or measures of lung function. Here, we aimed to develop and test the accuracy of a smartphone-based diagnostic algorithm that analyses five cough events and five patient-reported features (age, fever, acute or productive cough and wheeze) to detect asthma exacerbations.Methods: We conducted a double-blind, prospective, diagnostic accuracy study comparing the algorithm with expert clinical opinion and formal lung function testing. Results: One hundred nineteen participants >12 years with a physician-diagnosed history of asthma were recruited from a hospital in Perth, Western Australia: 46 with clinically confirmed asthma exacerbations, 73 with controlled asthma. The groups were similar in median age (54yr versus 60yr, p=0.72) and sex (female 76% versus 70%, p=0.5). The algorithm's positive percent agreement (PPA) with the expert clinical diagnosis of asthma exacerbations was 89% [95% CI: 76%, 96%]. The negative percent agreement (NPA) was 84% [95% CI: 73%, 91%]. The algorithm's performance for asthma exacerbations diagnosis exceeded its performance as a detector of patient-reported wheeze (sensitivity, 63.7%). Patient-reported wheeze in isolation was an insensitive marker of asthma exacerbations (PPA=53.8%, NPA=49%). Conclusions: Our diagnostic algorithm accurately detected the presence of an asthma exacerbation as a point-of-care test without requiring clinical examination or lung function testing. This method could improve the accuracy of telehealth consultations and might be helpful in Asthma Action Plans and patient-initiated therapy.

BACKGROUND: Motor neurone disease is a rare but debilitating illness with incomplete evidence regarding patients' symptom burden. Palliative care and generalist clinicians are often in-experienced in caring for these patients and assessing their needs. AIM: To identify the symptom prevalence and severity experienced by patients with motor neurone disease. Secondary objectives were to examine differences in symptom burden and clusters according to phenotype, functional status, palliative care provision and those in their last months of life. DESIGN: A point prevalence study assessing patient-reported symptoms using a modified IPOS-Neuro assessment tool, incorporating 41 symptom items. SETTING/PARTICIPANTS: Patients with motor neurone disease attending the State-wide Progressive Neurological Disease Service or inpatient unit at Calvary Health Care Bethlehem, Melbourne Australia, from March to December 2021. RESULTS: A total of 102 patients participated, the majority diagnosed with lumber-onset (30.4%), bulbar-onset (28.4%) and cervical-onset (25.5%) phenotypes. Patients experienced a median of 17 symptoms (range 2-32) with a median of 3 symptoms rated as severe/overwhelming (range 0-13). Motor and functional symptoms predominated, with differences in symptom clusters present according to phenotype. Patients had a higher number of severe/overwhelming symptoms if they were accessing palliative care services (p = 0.005), in their last 6 months of life (p = 0.003) and experiencing moderate or severe functional impairment (p < 0.001). CONCLUSIONS: Patients with motor neurone disease report high symptom burden. A validated motor neurone disease-specific symptom assessment tool is needed to accurately assess patients, including important variations in symptom clusters according to phenotype. Further research must focus on evidence-based treatment guidelines for symptoms experienced commonly and severely.

AIM: The incidence of anaphylaxis is increasing globally in tandem with changing environmental and lifestyle factors. There is very limited data on very early childhood presentations. We aim to assess changes in rates, characteristics and management of infant anaphylaxis in a paediatric ED over a 15-year period. METHODS: We conducted a retrospective study of children <2 years of age who presented with verified anaphylaxis comparing cases in years 2003-2007 with those in 2013-2017. Standardised information was collected on demographics, clinical presentation, management and triggers. RESULTS: Manually confirmed anaphylaxis rates in <2 year olds increased from 3.6 to 6.2 per 104 population (OR 1.7, 95% CI: 1.3-2.7; p < 0.001) with the greatest increase in <1 year olds. Anaphylaxis severity increased between 2003-2007 and 2013-2017 (OR 2.3, 95% CI: 1.2-4.3; p = 0.018). Failure to administer adrenaline was reduced in 2013-2017 (p = 0.007). Food was the leading anaphylaxis trigger (97.85%). CONCLUSION: This is the first study to suggest an increase in the incidence and severity of ED anaphylaxis presentations in children aged <2 years. Increased awareness of specific characteristics in this age group is required to facilitate timely recognition and optimal management. Further large-scale studies are warranted to understand underlying environmental drivers and find prevention strategies to reduce the burden of disease.

AIM: The aim of this study is to describe the individualized occupational performance issues identified by parents/carers and children prior to selective dorsal rhizotomy (SDR) surgery and analyse change up to 2 years post surgery in goal attainment and quality of life (QoL). METHOD: The Australian SDR Research Registry (trial registration: ACTRN12618000985280) was used to extract data for individualized goals, goal attainment and QoL based on the Canadian Occupational Performance Measure (COPM) and the Cerebral Palsy Quality of Life Questionnaire for Children (CP QOL-Child parent-proxy) at baseline and 1 and 2 years following SDR. Change in mean scores was analysed using linear mixed models. RESULTS: Fifty-two children had COPM scores at baseline and 1 and/or 2 years post, of which 28 had two QoL scores. COPM problem areas included leisure (n = 39), productivity (n = 37) and self-care (n = 173). The most common goals were walking (26.1%), participation in physical activities (17.7%) and transitions (14.1%). Mean COPM scores improved significantly between baseline to 1 year and baseline to 2 years (P < 0.001). Mean QoL scores improved between baseline to 1 year for functional QoL domains: participation and physical health (P = 0.003) and pain and impact of disability (P = 0.011). CONCLUSIONS: Collaborative goal setting is an integral part of family-centred rehabilitation practice. The COPM was an appropriate individualized outcome measure in identifying meaningful goals for our SDR cohort. Results demonstrate improved scores in goal attainment and improvement in functional QoL domains. This paper highlights the need to include outcomes that measure daily life experiences.

OBJECTIVE: To identify the characteristics of people with chronic obstructive pulmonary disease (COPD) who require hospitalisation for exacerbations. METHODS: People with COPD were recruited either during hospitalisation or from out-patient respiratory medicine clinics. Hospital admissions were tracked throughout the 5-months recruitment period. For participants who were admitted, hospital readmissions were tracked for at least 30 days following discharge. Participants were grouped as either needing; (i) no hospital admission during the study period (no admission; ø-A), (ii) one or more hospital admissions during the study period but no readmission within 30 days of discharge (no rapid readmission; ø-RR) or (iii) one or more hospital admissions with a readmission within 30 days of discharge (rapid readmission; RR). RESULTS: Compared with the ø-A group (n=211), factors that independently increased the risk of ø-RR (n=146) and/or RR (n=57) group membership were being aged >60 years, identifying as an Indigenous person (relative risk ratio, 95% confidence interval 7.8 [1.8 to 34.0]) and the use of a support person or community service for activities of daily living (1.5 [1.0 to 2.4]. A body mass index ≥25 kg/m2 was protective. CONCLUSIONS: Variables recorded at the bedside or in clinic provided information on hospitalisation risk.

AIM: To outline the development and examine the content and construct validity of a new tool, the Dyskinetic Cerebral Palsy Functional Impact Scale (D-FIS), which measures the impact of dyskinesia on everyday activities in children with cerebral palsy (CP). METHOD: D-FIS content was informed by a systematic review of dyskinesia outcome measures, in collaboration with children with dyskinetic CP, parents, caregivers, and expert clinicians. The D-FIS uses parent proxy to rate impact of dyskinesia on everyday activities. Construct validity was determined by examining internal consistency; known groups validity with the Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), Communication Function Classification System (CFCS), and Eating and Drinking Ability Classification System (EDACS); and convergent validity with the Barry-Albright Dystonia Scale (BADS). RESULTS: Fifty-seven parents of children (29 males, 28 females, mean [SD] age 11y 8mo [4y 4mo], range 2y 6mo-18y) completed the D-FIS. Correlation between D-FIS and GMFCS was r=0.86 (95% confidence interval [CI]: 0.77-0.91, p<0.001); MACS r=0.84 (95% CI: 0.73-0.90, p<0.001); CFCS r=0.80 (95% CI: 0.67-0.88, p<0.001); and EDACS r=0.78 (95% CI: 0.66-0.87). Correlation between D-FIS and BADS was r=0.77 (95% CI: 0.64-0.86, p<0.001). Cronbach's alpha was 0.96. INTERPRETATION: The D-FIS demonstrates good construct validity and high internal consistency. The D-FIS will be useful for identifying priorities for intervention. It adds to the measurement tool kit for children with dyskinetic CP by addressing functional impact of dyskinetic movements and postures. What this paper adds The Dyskinetic Cerebral Palsy Functional Impact Scale (D-FIS) assesses the perceived impact of dyskinesia on daily activities in children with cerebral palsy (CP). The D-FIS demonstrates good construct validity and high internal consistency. The D-FIS is a clinically feasible, family-centred tool that fills a current gap in the dyskinetic CP assessment toolkit.

AIM: To determine if robotic assisted gait training (RAGT) using surface muscle electrical stimulation and locomotor training enhances mobility outcomes when compared to locomotor training alone in children with cerebral palsy (CP). METHOD: Forty children (18 females, 22 males; mean age 8y 1mo, SD 2y 1mo; range 5y 1mo-12y 11mo) with CP in Gross Motor Function Classification System levels (GMFCS) III, IV, and V were randomly assigned to the RAGT and locomotor training (RAGT+LT) group or locomotor training only group (dosage for both: three 1-hour sessions a week for 6 weeks). Outcomes were assessed at baseline T1 (week 0), post-treatment T2 (week 6), and retention T3 (week 26). The primary outcome measure was the Goal Attainment Scale. Secondary outcome measures included the 10-metre walk test, children's functional independence measure mobility and self-care domain, the Canadian Occupational Performance Measure, and the Gross Motor Function Measure. RESULTS: There were no significant differences between the groups for both the primary and secondary outcome measures. All participants completed the intervention in their original group allocation. There were no reported adverse events. INTERPRETATION: The addition of RAGT to locomotor training does not significantly improve motor outcomes in children with CP in GMFCS levels III, IV, and V. Future studies could investigate health and well-being outcomes after locomotor training. WHAT THIS PAPER ADDS: Marginally ambulant and non-ambulant children with cerebral palsy can participate in locomotor training. Robotic assisted gait training when added to locomotor training does not appear to be any more effective than locomotor training alone.

AIM: Oral medications are often first-line medical management for children with cerebral palsy who have generalised dystonia; however, evidence for their effectiveness is limited and dosing practices are inconsistent. As a first step to improve consistency, this study aimed to examine current clinical practice of expert doctors for prescribing medications for children with dystonic cerebral palsy including prescribing patterns and combinations of medications used. METHODS: This was a prospective surveillance study of medical doctors working in major Australian centres who manage children with cerebral palsy. Each week over a continuous 6-month period, doctors completed a custom developed online survey for children seen that week with dystonic cerebral palsy for whom they prescribed a new medication to treat dystonia. RESULTS: Twenty-five doctors consented to participate, 16 of whom prescribed new medications for dystonia in children with cerebral palsy over the study period. There were 77 children who were prescribed new medications. Baclofen and gabapentin were prescribed most, followed by levodopa, trihexyphenidyl and diazepam. The most common combinations of medications were baclofen and diazepam or baclofen and gabapentin. Dosage regimens were variable, particularly for trihexyphenidyl and diazepam. CONCLUSION: Inconsistencies in dosing regimens remain for oral medication prescription by Australian doctors when managing dystonia in cerebral palsy. Future studies using the consensus of expert clinicians will be conducted to develop guidelines in an area where the evidence for individual medications is extremely limited.

BACKGROUND: Management of common childhood spiral tibial fractures, known as toddler's fractures, has not significantly changed in recent times despite the availability of immobilisation devices known as controlled ankle motion (CAM) boots. We compared standard therapy with these devices on quality-of-life measures. METHODS: A prospective randomised controlled trial, comparing immobilisation with an above-knee plaster of Paris cast (AK-POP) with a CAM boot in children aged 1-5 years with proven or suspected toddler's fractures presenting to a tertiary paediatric ED in Perth, Western Australia, between March 2018 and February 2020. The primary outcome measure was ease of personal care, as assessed by a Care and Comfort Questionnaire (eight questions scored from 0, very easy, to 8, impossible) completed by the caregiver and assessed during three treatment time-points and preintervention and postintervention. Secondary outcome measures included weight-bearing status as well as complications of fracture healing and number of pressure injuries. RESULTS: 87 patients were randomised (44 CAM boot, median age 2 (IQR 1.5-2.3), 71% male; 43 AK-POP, median age 2 (IQR 1.7-2.8), 80% male), a significant difference in the care and comfort score was demonstrated at all treatment time-points; with the AK-POP group reporting greater personal care needs on assessment on day 2, day 7-10 and 4-week review (all p≤0.001). Weight-bearing status was significantly different at day 7-10 (77.5% CAM vs 53.8% AK-POP, p=0.027). There was no difference in fracture healing or pressure areas between the two treatment groups. CONCLUSIONS: Immobilisation of toddler's fractures in a CAM boot allows faster return to activities of daily living and weight-bearing without any effect on fracture healing. TRIAL REGISTRATION NUMBER: Australian New Zealand Clinical Trials Registry (ACTRN12618001311246).

STUDY DESIGN: This is a noninferior, single-blind, randomized controlled trial. INTRODUCTION: Joint stiffness is common after plaster cast immobilization for simple phalanx and metacarpal fractures in children. The limited literature suggests this joint stiffness in children resolves without one-on-one therapy; however, without robust studies confirming that there is no detrimental effect from withdrawing treatment, many children are still referred. PURPOSE OF THE STUDY: The purpose of this study was to determine if an educational handout for self-management of stiffness is noninferior to one-on-one hand therapy for achieving full range of motion (ROM). METHODS: Participants were randomly assigned to group one who received the handout or group two who received hand therapy in addition to the handout. The ROM was measured by composite flexion and total active motion (TAM). The noninferiority margin was 10% difference between the two groups in the proportion of participants who achieved full ROM at two weeks after cast removal. RESULTS: Sixty participants in each group completed the study. Group difference for composite flexion was 1.7% (95% CI: -3.9% to 7.2%), demonstrating noninferiority. Group difference for TAM was inconclusive at 8.3% (95% CI: -2.1% to 18.7%). Sensitivity analysis adjusting for participants with full composite flexion at the baseline resulted in the group difference for composite flexion of 3.1% (95% CI: -3.6% to 9.8%), maintaining noninferiority, but group difference for TAM at 10.4% (95% CI: 0.0% to 20.9%), was inconclusive with the handout group significantly worse. CONCLUSION: An educational handout is noninferior to hand therapy for achieving full ROM in composite flexion but not TAM. This needs to be taken into consideration for changing clinical practise.

BACKGROUND: Autologous hematopoietic stem cell transplantation (aHSCT) using hematopoietic progenitor cells (HPCs) has become an important therapeutic modality for patients with high-risk malignancies. Current literature on standardized method for HPC apheresis in children is sparse and failure rate reported as high as 30%. PATIENTS/METHODS: A retrospective study of 125 pediatric patients with high-risk malignancies undergoing aHSCT in Western Australia between 1997 and 2016 was conducted. RESULTS: Mobilization was achieved by means of chemotherapy and granulocyte colony-stimulating factor (G-CSF). Patients underwent apheresis the day after CD34+ counts reached ≥20/µL and an additional dose of G-CSF. Peripheral arterial and intravenous lines were inserted in pediatric intensive care unit under local anesthetic and/or sedation, omitting the need for general anesthesia as well as facilitating an uninterrupted apheresis flow. Larger apheresis total blood volumes were processed in patients weighing ≤20 kg. The minimal dose of ≥2 × 106 CD34+ cells/kg was successfully collected in 98.4% of all patients. The optimal dose of 3-5 × 106 CD34+ cells/kg was collected in 96% of patients scheduled for a single aHSCT, 87.5% for tandem, and 100% for triple aHSCT. All HPC collections were completed in one apheresis session. Mobilization after ≤3 chemotherapy cycles and cycles including cyclophosphamide resulted in a significantly higher yield of CD34+ cells. CONCLUSION: Our approach to HPC mobilization by means of chemotherapy and single myeloid growth factor combined with optimal collection timing facilitated by continuous apheresis flow resulted in highly effective HPC harvest in children and adolescents with high-risk cancers.

BACKGROUND: The aim of this study is to contribute to the knowledge base on the long-term outcomes of evidence-based medical interventions used to improve gross motor function in children and adolescents with Cerebral Palsy. METHOD: Prospective cohort study of children with Cerebral Palsy in the birth years 2000-2009 attending a tertiary level service for children with Cerebral Palsy who's first recorded Gross Motor Function Classification System level was II. RESULTS: A total of 40 children were eligible for the study, of whom 28 (72.7%) enrolled. The Botulinum toxin A treatment for this cohort, (median and interquartile ranges) were: total number of lower limb Botulinum toxin A injections 11 (6.7, 5.5); total dose of Botulinum Toxin A per lower limb treatment 6.95 u/kg (4.5, 11); and dose of Botulinum Toxin u/kg/muscle 2.95 (2.2, 4). For all 28 subjects there was a median of 15 (8.5 to 22) Gross Motor Function Classification System level recordings: six of the 28 children (21.4%) improved from level II to level I, the remaining 22 children remained stable at level II (78.6%). In this highly treated population, the average 66 item Gross Motor Function Measure score for the 22 children in level II was 72.55, which is consistent with the mean of 68.5 reported in the original Ontario cohort. CONCLUSION: This cohort study has confirmed that children with Cerebral Palsy, Gross Motor Function level II treated at a young age with repeated doses of Botulinum Toxin A within an integrated comprehensive service, maintain or improve their functional motor level at a later age.

AIM: Bronchiolitis is the commonest cause of hospitalisation for infants. Evidence-based Australasian bronchiolitis guideline was developed and introduced in 2017. This audit was to determine if the knowledge translation process of the updated local tertiary hospital bronchiolitis guideline (based on the Australasian guideline) reduced unnecessary interventions. METHODS: A retrospective chart review of infants with bronchiolitis diagnosis during the pre-guideline (1 July to 31 August 2015) and post-guideline (1 July to 31 August 2017) period, with the primary outcome of the number/proportion of unnecessary interventions. RESULTS: Presentations between 1 July to 31 August 2015 (n = 465) were compared with 2017 (n = 343). There was no difference in undertaking chest X-ray (24 (5.2%) vs. 17 (5.0%), odds ratio (OR) 0.98 (95% confidence interval (CI) 0.71-1.35), P = 0.911), salbutamol (23 (4.9%) vs. 10 (2.9%), OR 0.86 (95% CI 0.65-1.13), P = 0.279), glucocorticoids (2 (0.4%) vs. 5 (1.5%), OR 1.89 (95% CI 0.83-4.31), p = 0.129), antibiotics (11 (2.4%) vs. 5 (1.5%), OR 0.86 (95% CI 0.65-1.15), P = 0.307) or nasopharyngeal aspirate (172 (37%) vs. 124 (36.2%), OR 1.00 (95% CI 0.87-1.67), P = 0.937) in hospital. Adrenaline was not administered in both years. There was reduced hospital admissions (303 (65.2%) vs. 192 (56.0%), OR 0.82 (95% CI 0.71-0.95), P = 0.008) with no difference in paediatric intensive care unit admissions (10 (2.2%) vs. 8 (2.3%), OR 1.04 (95% CI 0.65-1.67), P = 0.863). CONCLUSION: The dissemination process of the updated local hospital bronchiolitis guideline did not show any statistically significant reduction of unnecessary interventions in the hospital. Further studies are required to determine the effective process to instigate changes in health services.

BACKGROUND: Suboptimal vitamin D levels during critical periods of immune development have emerged as an explanation for higher rates of allergic diseases associated with industrialization and residing at higher latitudes. OBJECTIVE: We sought to determine the effects of early postnatal vitamin D supplementation on infant eczema and immune development. METHODS: By using a double-blind randomized controlled trial, newborn infants were randomized to receive vitamin D supplementation (400 IU/d) or a placebo until 6 months of age. Some infants also wore personal UV dosimeters to measure direct UV light (290-380 nm) exposure. Infant vitamin D levels were measured at 3 and 6 months of age. Eczema, wheeze, and immune function outcomes were assessed at 6 months of age. RESULTS: At 3 (P < .01) and 6 (P = .02) months of age, vitamin D levels were greater for the vitamin D-supplemented group than the placebo group, but there was no difference in eczema incidence between groups. Infants with eczema were found to have had less UV light exposure (median, 555 Joules per square meter [J/m2; interquartile range, 322-1210 J/m2]) compared with those without eczema (median, 998 J/m2 [interquartile range, 676-1577 J/m2]; P = .02). UV light exposure was also inversely correlated with IL-2, GM-CSF, and eotaxin production to Toll-like receptor ligands. CONCLUSION: This study is the first to demonstrate an association between greater direct UV light exposures in early infancy with lower incidence of eczema and proinflammatory immune markers by 6 months of age. Our findings indicate that UV light exposure appears more beneficial than vitamin D supplementation as an allergy prevention strategy in early life.

AIM: Nutritional deprivation, inadequate diet and food insecurity are common refugee experiences. The growth and nutritional status of paediatric refugees following resettlement in developed countries and the related interplay with socio-economic factors remain less defined; this study aims to describe these features. METHODS: Standardised dietary, medical and socio-demographic health assessments of new refugee patients attending a multidisciplinary paediatric Refugee Health Service (RHS) in Western Australia between 2010 and 2015 were analysed. RESULTS: Demographic data from 1131 paediatric refugees are described (age 2 months to 17.8 years). The majority experienced socio-economic disadvantage, had limited parental education and required interpreters. Nutritional deficiencies were common but varied across ethnicities: iron deficiency (ID) (12.3%), anaemia (7.3%) and inadequate dairy intake (41.0%). A third of children (32.6%) did not consume meat. Infant breastfeeding was sustained (77.8%) in infants <12 months. Prolonged breastfeeding (44.9% aged 12-24 months) was associated with an increased risk of ID (odds ratio 4.0, 95% confidence interval 1.4-11.6). Median body mass index increased significantly for those >24 months between referral and RHS assessment (median period 1.8 months). Overall, 27.1% required additional formal dietetic follow-up, with higher nutritional concerns in refugee children <24 months compared to older patients. CONCLUSIONS: Identification of frequent post-settlement nutritional concerns has been captured through structured multidisciplinary paediatric health screening. Specific screening for socio-economic influencing factors, including education, poverty and food insecurity, during refugee clinical assessments is recommended. Development of targeted, culturally appropriate parental education resources and interventions may improve management following resettlement. Longitudinal research assessing resettlement growth trajectories is required.

AIM: This study aimed to track alterations in muscle volume for 6 months in children with cerebral palsy (CP) after the first exposure to botulinum neurotoxin A (BoNT-A), a commonly used focal spasticity treatment. METHOD: Eleven ambulant children (eight males, three females) with spastic CP, mean age 8 years 10 months (SD 3y 1mo) participated. Participants received injections to the affected gastrocnemius. The muscle volume of the gastrocnemius, soleus, tibialis anterior, and hamstrings was measured using magnetic resonance imaging. Muscle volume was normalized to bone length, and changes analysed relative to baseline. Assessments were conducted 1 week before, and 4 weeks, 13 weeks, and 25 weeks after BoNT-A treatment. RESULTS: All children demonstrated positive clinical and functional gains. Muscle volume of the injected gastrocnemius was found to be significantly reduced at 4 weeks (-5.9%), 13 weeks (-9.4%), and 25 weeks (-6.8%). Significant increases in normalized soleus muscle volume were identified at each follow-up, while hamstrings showed significant increase at 4 weeks only. INTERPRETATION: Absolute and normalized muscle volume of the injected muscle reduces after first BoNT-A exposure, and does not return to baseline volume by 25 weeks. Hypertrophy is seen in the soleus up to 25 weeks; the volume of the plantar flexor compartment is stable. WHAT THIS PAPER ADDS: Muscle atrophy after first botulinum neurotoxin A (BoNT-A) exposure in children with cerebral palsy is noted. Mild BoNT-A-induced muscle atrophy is still apparent 6 months after BoNT-A exposure. Hypertrophy is evident in soleus after gastrocnemius BoNT-A exposure. Total plantarflexor volume is unchanged.

AIM: To determine the incidence of common adverse events after botulinum toxin A (BoNT-A) injections in children with cerebral palsy (CP) and to identify whether the severity of CP influences the incidence of adverse events. METHOD: This was an observational study of patients attending a BoNT-A clinic at a tertiary paediatric hospital (2010-2014). Data examined included procedural adverse events at the time of injection and at follow-up. Systemic adverse events were defined as lower respiratory tract illnesses, generalized weakness, dysphagia, and death. Severity of CP was categorized by the Gross Motor Function Classification System (GMFCS). The relationships between GMFCS and adverse events were analysed using negative binomial regression models. RESULTS: In total, 591 children underwent 2219 injection episodes. Adverse events were reported during the procedure (130 [6%] injection episodes) and at follow-up (492 [22%] injection episodes). There were significantly increased rates of systemic adverse events in injection episodes involving children in GMFCS level IV (incidence rate ratio [IRR] 3.92 [95% confidence interval] 1.45-10.57]) and GMFCS level V (IRR 7.37 [95% confidence interval 2.90-18.73]; p<0.001). INTERPRETATION: Adverse events after BoNT-A injections are common but mostly mild and self-limiting. Children in GMFCS levels IV and V are at increased risk of systemic adverse events. The relationship between CP severity and BoNT-A adverse events is complex and further research is required to better understand this relationship. WHAT THIS PAPER ADDS: Adverse events reported at the time of botulinum toxin A injection occurred in 6% of injection episodes. Adverse events were reported at follow-up in 22% of injection episodes. Children in Gross Motor Function Classification System (GMFCS) levels IV and V have increased rates of systemic adverse events. Children in GMFCS levels IV and V report less local weakness and pain.

BACKGROUND: Of children with hemiplegic cerebral palsy, 75% have impaired somatosensory function, which contributes to learned non-use of the affected upper limb. Currently, motor learning approaches are used to improve upper-limb motor skills in these children, but few studies have examined the effect of any intervention to ameliorate somatosensory impairments. Recently, Sense© training was piloted with a paediatric sample, seven children with hemiplegic cerebral palsy, demonstrating statistically and clinically significant change in limb position sense, goal performance and bimanual hand-use. This paper describes a protocol for a Randomised Controlled Trial of Sense© for Kids training, hypothesising that its receipt will improve somatosensory discrimination ability more than placebo (dose-matched Goal Directed Therapy via Home Program). Secondary hypotheses include that it will alter brain activation in somatosensory processing regions, white-matter characteristics of the thalamocortical tracts and improve bimanual function, activity and participation more than Goal Directed Training via Home Program. METHODS AND DESIGN: This is a single blind, randomised matched-pair, placebo-controlled trial. Participants will be aged 6-15 years with a confirmed description of hemiplegic cerebral palsy and somatosensory discrimination impairment, as measured by the sense©_assess Kids. Participants will be randomly allocated to receive 3h a week for 6 weeks of either Sense© for Kids or Goal Directed Therapy via Home Program. Children will be matched on age and severity of somatosensory discrimination impairment. The primary outcome will be somatosensory discrimination ability, measured by sense©_assess Kids score. Secondary outcomes will include degree of brain activation in response to a somatosensory task measured by functional MRI, changes in the white matter of the thalamocortical tract measured by diffusion MRI, bimanual motor function, activity and participation. DISCUSSION: This study will assess the efficacy of an intervention to increase somatosensory discrimination ability in children with cerebral palsy. It will explore clinically important questions about the efficacy of intervening in somatosensation impairment to improve bimanual motor function, compared with focusing on motor impairment directly, and whether focusing on motor impairment alone can affect somatosensory ability. TRIAL REGISTRATION: This trial is registered with the Australian New Zealand Clinical Trials Registry, registration number: ACTRN12618000348257. World Health Organisation universal trial number: U1111-1210-1726.

OBJECTIVE: To determine the prevalence of generalized joint hypermobility (GJH) in a large cohort of Australian children and determine the associations between GJH and musculoskeletal pain. STUDY DESIGN: This is a cross-sectional analysis of the Western Australian Pregnancy Cohort (Raine) Study. Hypermobility was measured in 1584 participants at 14 years of age using the Beighton scoring system, along with a range of other factors including musculoskeletal pain status. Logistic regression models were used to assess independent associations of GJH with factors of interest. RESULTS: The prevalence of GJH was 60.6% and 36.7% in girls and boys, respectively, when defined as a Beighton score of ≥4; when defined as ≥6, it was 26.1% and 11.5%. In girls, positive associations between GJH and higher socioeconomic status and better motor competence were observed. In boys, positive associations between GJH and lower body mass index were observed. After adjusting for potential confounders, an association between number of pain areas in the last month and made worse with sport were identified in boys but not girls. CONCLUSION: The high prevalence rates of GJH as defined by commonly used Beighton cutoff values in this cohort highlight the need to question the appropriateness of these cutoffs in future studies. Future prospective studies of the association between GJH and musculoskeletal pain should be adjusted for confounding variables identified in this study, and be powered for sex-specific analyses owing to the differing prevalence rates and hypermobility correlates in male and female samples.
