RESUMO
OBJECTIVE: To investigate the utility of melatonin supplementation as a treatment option for individuals with sleep disturbance after traumatic brain injury (TBI). DATA SOURCES: A systematic search was conducted in 6 electronic databases (Medline, AMED, CINAHL, Embase, Scopus, and SPORTDiscus) from earliest records to April 2022. STUDY SELECTION: Studies were eligible for inclusion if they met the following criteria: a) human participants with sleep disturbance after TBI, b) melatonin or melatonergic agent used as an intervention to treat sleep disturbance, and c) outcomes of melatonin administration reported. All TBI severity types (mild, moderate, and severe) were eligible. The initial search retrieved a total of 595 articles, with 9 studies meeting the eligibility criteria. DATA EXTRACTION: Two reviewers independently extracted data from eligible studies and assessed methodological quality. Extracted data consisted of participant and injury characteristics, melatonin interventional properties, and sleep outcome. Methodological quality was assessed via the Downs and Black checklist. DATA SYNTHESIS: A total of 251 participants with TBI-induced sleep disturbance (mean age range: 14.0-42.5 years) were included. Melatonin, Circadin (prolonged-release melatonin), or Ramelteon (melatonin receptor agonist) were administered. Dosages and intervention duration ranged from 2 to 10 mg and 3 to 12 weeks, respectively. Eight out of 9 studies reported positive outcomes after melatonin treatment. Significant improvements in subjective sleep quality, objective sleep efficiency, and total sleep time were found with melatonin. Reductions in self-reported fatigue, anxiety, and depressive symptoms were also observed with melatonin treatment. No serious adverse events were reported after melatonin administration. CONCLUSION: Melatonin has good tolerability after short-term use and the potential to be a therapeutic agent for those with sleep disturbance after TBI. Melatonin was shown to be beneficial to sleep quality, sleep duration, and sleep efficiency. Additional clinically relevant outcomes of improved mental health suggest that melatonin use may be a promising treatment option for individuals experiencing co-occurring disorders of mood and sleep disturbance post-injury.

OBJECTIVES: To investigate the relationship between sleep disturbance, neurocognition, symptom severity, and recovery in children and adolescents with concussion. Sex-related comparisons were also examined. SETTING: Pediatric tertiary referral concussion clinic. PARTICIPANTS: Children and adolescents (aged 6-18 years; n = 554) diagnosed with concussion. DESIGN: Cross-sectional retrospective study. MAIN MEASURES: Assessment data were obtained from Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) Applications. Sleep disturbance was quantified using the sleep-related domains of the Post-Concussion Symptom Scale (PCSS) and self-report sleep duration. Sleep duration was categorized as short (<7 hours), intermediate (7-9 hours), and long (≥9 hours). Outcome measures included neurocognition, measured via composite scores of ImPACT cognitive domains (verbal memory, visual memory, visual motor speed, reaction time); symptom severity, using the PCSS; and concussion recovery time (days). RESULTS: Short sleep resulted in significantly poorer verbal memory ( P = .03), visual memory ( P = .02), and reaction time ( P = .01). Sleep disturbance was strongly associated with total symptom burden (ρ = 0.90, P < .001). Recovery time, median (interquartile range), was significantly prolonged with short sleep, 61 (30-136) days, compared with intermediate, 38 (21-72) days, and long, 34 (19-71) days, sleep ( P < .001). Overall, female participants demonstrated significantly longer recovery times than male participants (mean 91 ± 95 vs 58 ± 85 days, P < .001). Females exhibited similar concussion recovery times irrespective of reported sleep duration ( P = .95), whereas mean recovery time in males was significantly longer with short sleep (84 ± 82 days) than with intermediate (61 ± 106 days) and long (49 ± 62 days) sleep ( P < .001). CONCLUSION: Sleep disturbance following concussion poses as a promising modifiable risk factor to alleviate postinjury impairments, including cognitive deficits and symptom burden. Female children were found to experience more severe concussion symptoms and protracted recovery times than their male counterparts. Investigations into the factors that may contribute to sex-related differences following concussion are warranted.

OBJECTIVE: Management of sport-related and recreation-related concussions (SRCs) in children and adolescents is challenging as brain maturation affects prognosis. However, impact seizure was removed as a prognosis modifying factor in children and adolescents with SRCs in the 2017 consensus statement on concussion in sport, based mostly on adult literature. Therefore, this study evaluates the association of impact seizure on the recovery in children and adolescents with SRCs. DESIGN: Retrospective matched case-control study. SETTING: Tertiary pediatric sports medicine service, from January 1, 2015, to June 30, 2022. PATIENTS: A cohort of 452 patients, aged 7 to 18 years, with new episode of SRC was seen. From this cohort, 396 patients were included in the analysis, including 22 with impact seizures. Controls were generated using the propensity score matching approach. Patients with moderate or severe traumatic brain injury or incomplete treatment were excluded. INDEPENDENT VARIABLE: Impact seizure during SRC. MAIN OUTCOME MEASURES: Primary outcome was recovery duration in number of days. RESULTS: The median recovery duration was longer in the cases (73 days, interquartile range [IQR] = 38-143 days) as compared with controls (49.5 days, IQR = 30.5-93.5 days). There was no difference in patients with prolonged recovery (ie >28 days) between both groups (OR 1.6, 95% CI, 0.4-6.6, P = 0.505). CONCLUSIONS: Impact seizures prolonged the recovery duration in children and adolescents with SRCs and have a potential concussion modifying prognostic role. These findings could help provide evidence-based management principles for children and adolescents with SRCs in subsequent concussion consensus statements.
RESUMO
OBJECTIVES: To explore the relationship between symptoms and exercise tolerance in adolescents following concussion. METHODS: A retrospective analysis of 417 adolescents who attended a concussion service between January 2015 and April 2021 was performed, with 149 meeting eligibility criteria for inclusion. Post-Concussion Symptom Scale (PCSS) and graded exercise tolerance time (min) were assessed at initial and follow-up visits. Spearman's correlation was used to examine the relationship between PCSS scores and exercise time. RESULTS: Adolescents (n = 149, 13.9 ± 1.7 years, 66.4% male) presented at 28.6 ± 19.7 days post-injury. Statistically significant correlations were identified between initial (r = -0.36, p < .001) and follow-up (r = -0.41, p < .001) PCSS scores and exercise time among all participants. Initial PCSS and initial exercise time were inversely correlated for males (r = -0.24, p = .018) and females (r = -0.22, p = .127). Follow-up PCSS and follow-up exercise time were inversely correlated for males (r = -0.30, p = .003) and females (r = -0.35, p = .014). CONCLUSION: There is a statistically significant relationship between higher PCSS and poorer exercise time and both factors should be considered together to provide the most accurate assessment, particularly in females.

OBJECTIVE: To determine whether graded exercise testing can predict recovery trajectory of concussion in children and adolescents. DESIGN: Prospective study. SETTING: Children's Hospital, Westmead, Australia. PARTICIPANTS: One hundred thirty-nine children aged 12 to 16 years at 5 to 7 days after an acute concussive injury. INTERVENTION: Graded exercise testing on a treadmill at the subacute phase to assess symptom provocation and determine clinical recovery indicating readiness to commence a return to activity (RTA) protocol. Exercise time to symptom exacerbation and clinical recovery were measured. MAIN OUTCOME MEASURES: Standard concussion assessment and clinical testing (neurocognitive, vestibular/ocular, and balance) were conducted to determine major clinical drivers/indicators. RESULTS: Participants (mean age 12.4 ± 2.8 years, 73% male) had a confirmed sport-related concussion. The main clinical drivers identified on exercise testing were headache, balance, and vestibular dysfunction. Participants fell into 1 of 2 groups, exercise-tolerant (54%) and exercise-intolerant (46%). Exercise-tolerant patients showed mild clinical indicators, no symptom exacerbation during 10.3 ± 3.3 minutes of exercise, were safely transitioned to a RTA protocol, and recovered within 10 days. Exercise-intolerant patients had high clinical indicators, significant symptom exacerbation at 4.2 ± 1.6 minutes of exercise, and prolonged recovery of 45.6 days. No adverse effects from exercise were reported in either group. Combined use of provocative exercise and clinical testing was 93% predictive of outcome. CONCLUSIONS: Exercise testing during the subacute phase after a concussion can predict longer recovery. Exercise testing can identify a unique window where patients can be safely transitioned to activity, enabling clinicians to better inform patients and families, allocate resources and streamline care.

OBJECTIVES: We hypothesized that a submaximal step test would be associated with readiness to commence graded exercise in children and adolescents with concussion. METHODS: Children and adolescents aged 8 to 18 years performed standard concussion clinical assessment for vestibular/ocular and balance impairment, and exercise examination utilizing the 3-minute Kasch Pulse Recovery test (KPR) and a symptom-limited graded exercise test (GXT). Outcome measures included activity readiness and symptom exacerbation. RESULTS: Forty-five participants (mean age 13.2 ± 2.1 years, 76% male) had a confirmed concussion (73% sports-related). Some participants required follow-up testing giving 75 clinical presentations. Sensitivity and specificity of the KPR were 100% and 95.7%, respectively. Area under the receiver operating characteristics curve was 0.979. Activity readiness to GXT and KPR was strongly associated (χ = 21.672, P < .001), while symptom exacerbation showed a significant correlation between testing methods (r = 0.796, P < .001). Better exercise performance on GXT and KPR was significantly correlated with normal Vestibular/Ocular Motor Screening (rs = -0.380, P = .010, and rs = -0.281, P = .017, respectively) and Modified Balance Error Scoring System (rs = -0.452, P < .001, and rs = -0.301, P = .010, respectively). CONCLUSION: The KPR is a simple and practical tool to determine whether it is appropriate for a child or adolescent with concussion to commence graded exercise.

Young athletes are specialising in sports at a younger age, placing the developing musculoskeletal system under considerable stress. Overuse injuries such as apophysitis are chronic in nature and account for a large proportion of musculoskeletal injuries suffered by young athletes; however, with an increased emphasis on success in sport, tendinopathy and fatigue fractures are now being reported with increasing frequency, in the adolescent population. Correct diagnosis and early protection, rest, ice, compression and elevation therapy is critical, along with supervised rehabilitation an expert in paediatric and adolescent sports medicine. Acute traumatic knee injury and ankle sprain account for most acute injuries. Although most are soft tissue in nature, radiography may be useful in specific situations before early initiation of protection, rest, ice, compression and elevation therapy. These injuries will also require follow-up by an expert in paediatric and adolescent sports medicine to confirm the diagnosis and instigate ongoing rehabilitation and/or orthopaedic referral. Many of these injuries are preventable and due consideration should be given to simple prevention strategies.

BACKGROUND: Awareness of concussive head injury continues to grow, aided by greater understanding of the neurobiological underpinnings of concussions and its short-term and long-term consequences. Younger players who are in the midst of their neurodevelopmental trajectory continue to be placed at risk; therefore, more must be done to educate clinicians, parents, coaches and players alike in this area. Our understanding of concussive injury is evolving and more integrated models of care are being developed so as to provide patients with the holistic model of care needed in the post-concussive context. OBJECTIVE: In this article, we outline a contemporary perspective on concussion, and address an evidence-based approach to children and adolescents who have suffered a concussive injury. DISCUSSION: Good clinical care of a patient with concussion by the primary care physician is the best prevention of adverse outcomes. The ability of the primary care physician to recognise when to treat and when to refer will be an important agent for change in this field.

BACKGROUND: Exercise is widely understood to improve health outcomes in children and adolescents and to contribute to the prevention and management of many chronic conditions. Australian children are not currently meeting the recommended physical activity guidelines, and these habits are likely to extend into adulthood without intervention. OBJECTIVE: The aim of this paper is to provide general practitioners (GPs) with the tools to perform a basic exercise assessment with children and adolescents and an understanding of the core principles of exercise prescription for general and special paediatric populations. DISCUSSION: GPs are limited by time often precluding the assessment of exercise levels in children and adolescents unless it is immediately relevant to their presentation. This article discusses simple methods of assessing physical activity, the importance of appropriately prescribed exercise and its benefits for physical, psychological and social health and wellbeing.

Aim: To examine the impact of concussion on objective measures of school performance. Materials & methods: Population-based matched cohort study using linked health and education records of young people aged ≤18 years hospitalized with concussion in New South Wales, Australia, during 2005-2018, and matched comparisons not hospitalized with any injury. Results: Young people with concussion had higher risk of not achieving the national minimum standards for literacy and numeracy assessments, ranging from 30% for numeracy to 43% for spelling, and not completing high school, ranging from 29% for year 10 to 77% for year 12, compared with matched peers. Conclusion: Young people hospitalized with concussion have impaired school performance compared with uninjured matched peers.
RESUMO
OBJECTIVES: The objective of this study was to describe the characteristics and outcome of pediatric patients presenting to an emergency department (ED) following out-of-hospital primary cardiac arrest (OHPCA), to determine if long-term survival is influenced by specific resuscitation interventions. METHODS: This was a prospective observational study of cases of OHPCA during sport or exertion in young patients presenting to an ED over a 5-year period. Cases were identified from a resuscitation database, which documented patient demographics, nature of event, emergency treatment, response times, and clinical progress. These data were analyzed to determine outcomes. RESULTS: Nine children were identified who presented following OHPCA during the study period. The mean age was 10.7 (±4.2) years. All were subsequently diagnosed with an underlying primary cardiac disorder. Six patients (66.6%) survived to make a full recovery. All patients who survived had received early chest compressions (within 5 minutes) and early defibrillation (within 10 minutes). The initial cardiac arrest rhythm in all survivors had been an electrically cardiovertable rhythm. Five (83%) of the 6 survivors did not receive epinephrine during resuscitation. CONCLUSIONS: The importance of early chest compressions and defibrillation in collapsed young athletes is highlighted in this report. These interventions can result in full long-term neurological recovery. Use of epinephrine in these patients may be dangerous. We suggest that special consideration should be given to this subgroup of patients in the development of future resuscitation guidelines.

OBJECTIVES: Delayed treatment for paediatric concussion may impact recovery trajectory. This study aims to determine the relationship between time to evaluation and concussion recovery in children and adolescents. DESIGN: Retrospective cross-sectional study. METHODS: Records from 341 children and adolescents, aged 7-18â¯years, from a tertiary referral concussion clinic were analysed. All participants were assessed using a standardised concussion test battery by a specialist concussion physician and graded exercise testing. Evaluation time was defined as the number of days from injury occurrence to first presentation at the concussion clinic. Three distinct time to evaluation periods were categorised as: early evaluation (<14â¯days), mid evaluation (14-28â¯days), and late evaluation (>28â¯days). The main outcome measure was recovery time (days). RESULTS: A total of 341 participants (mean age 13.0⯱â¯2.3, 74% male) were included in the study. Of these, 89 received evaluation during the early phase (mean age 12.2⯱â¯2.5, 65% male), 124 during the mid phase (mean age 13.1⯱â¯2.2, 81% male) and 128 during the late phase (mean age 13.5⯱â¯2.1, 75% male) following injury. Participants receiving late evaluation took three times longer to recover (mean 148.0â¯days, 95% CI: 121.1-173.9) compared to early (mean 38.7â¯days, 95% CI: 30.7-46.7) and mid (mean 51.5â¯days, 95% CI: 39.7-63.4) evaluation. There was a strong positive correlation between recovery time and evaluation time (râ¯=â¯0.66, pâ¯<â¯0.001). CONCLUSIONS: Delaying time to evaluation following a concussion can significantly prolong recovery from injury in children and adolescents.

BACKGROUND: Asthma in the pediatric population imposes a significant burden on the Australian health care system. The lack of a standardized asthma assessment tool is an area that needs to be addressed. OBJECTIVE: To validate the pulmonary index score (PIS) against the National Asthma Council Guidelines (NACG) asthma assessment. METHODS: The project was approved by The Children's Hospital at Westmead Human Research Ethics Committee. Sixty-five patients aged 1 to 12 years with acute asthma were assessed independently using both the PIS and the NACG on presentation to the emergency department. RESULTS: These results indicate that the PIS (1) has high internal consistency (Cronbach α = .835); (2) correlates well with the NACG, with significant differences in PIS values across different NACG severity categories; (3) predicts with good sensitivity (85% for nonmild cases and 88% for severe cases) and specificity (75% for nonmild cases and 77% for severe cases) the various categories of asthma severity according to the NACG; and (4) significantly differs between admitted (mean PIS = 8.4) and nonadmitted (mean PIS = 5.0) patients. CONCLUSION: Use of the PIS may provide an objective and standardized approach to the assessment and monitoring of asthma in children.

OBJECTIVE: To increase the evidence base by characterizing various features of pediatric sports-related abdominal injuries. DESIGN: A review of the trauma database at The Children's Hospital at Westmead was undertaken for all abdominal injuries presenting to the emergency department between 2001 and 2006. SETTING: The Children's Hospital at Westmead is a tertiary-level pediatric trauma center servicing Sydney's west. It sees approximately 50,000 patients a year. PARTICIPANTS: Only those injuries occurring during an organized sport were included for analysis. Thirty-three of the original 513 patients were eligible for inclusion. MAIN OUTCOME MEASURES: The data collected included basic demographics, mechanism of injury, sport injury, time to presentation, length of stay, diagnoses, treatment, and complications. Injury severity scores were assigned retrospectively. RESULTS: Males sustained more injuries than females. Collisions and falls were the most common modes of injury. Rugby was the most common sport for injury. Most patients presented within 12 hours, and most presented with musculoskeletal injuries. Injury severity was usually mild; treatment, conservative; length of stay, short; and complications, uncommon. When characteristics were compared by sex, males had mostly collision injuries in high-impact/contact sports, with females having more falls in other sports. When characteristics were compared by age, the only statistically significant difference was in the organ injured: older children had more single solid organ injuries, and younger children had more multiple and hollow viscus injuries. CONCLUSIONS: Sports-related abdominal injuries in children are mostly minor and not as common as other injury mechanisms. Despite this, they can be serious, with early diagnosis often delayed because of their subtle nature. Sports-related abdominal injuries in children require a high index of suspicion in the part of the clinician if they are to be recognized early and managed effectively.

Many countries are stockpiling face masks for use as a nonpharmaceutical intervention to control virus transmission during an influenza pandemic. We conducted a prospective cluster-randomized trial comparing surgical masks, non-fit-tested P2 masks, and no masks in prevention of influenza-like illness (ILI) in households. Mask use adherence was self-reported. During the 2006 and 2007 winter seasons, 286 exposed adults from 143 households who had been exposed to a child with clinical respiratory illness were recruited. We found that adherence to mask use significantly reduced the risk for ILI-associated infection, but <50% of participants wore masks most of the time. We concluded that household use of face masks is associated with low adherence and is ineffective for controlling seasonal respiratory disease. However, during a severe pandemic when use of face masks might be greater, pandemic transmission in households could be reduced.

OBJECTIVES: To quantify and describe the incidence, cost, and temporal trends of sports injury-related hospitalisations in Australian children over a 10-year period. DESIGN: Retrospective population-based cohort study. METHODS: This study used linked hospitalisation and mortality data of children aged ≤16 years who were hospitalised for sports-related injury in Australia from 1 July 2002 to 30 June 2012. Age-standardised incidence rates were calculated with 95% confidence intervals (CI). Negative binomial regression was used to examine change in temporal trends in incidence rates. RESULTS: There were 130,167 sports injury-related hospitalisations during the 10-year study period. The overall annual incidence rate was 281.0 (95%CI: 279.5, 282.6) per 100,000 population. Males and older children were more frequently hospitalised than their female and younger counterparts. The most common sports activities resulting in hospitalisation were team ball sports (43.1%) and wheeled non-motor sport (22.3%). There was no significant annual decline in the overall incidence rate during the 10-year study period (-1.0% [95%CI: -3.0%, 1.0%]). The estimated total hospital treatment cost was $396 million, with an estimated mean cost per injured child of $3058. CONCLUSIONS: There has been no significant decline in sports injury-related hospitalisation rates among Australian children during 2002-03 to 2011-12. This may suggest that sports injury prevention initiatives in Australia to date have been inadequate to produce population-level reduction in sports injury-related hospitalisations. It is recommended that a national injury prevention strategy to reduce the burden of sports injuries among Australian children is developed and implemented.

OBJECTIVE: To reanalyze data from two previous studies to provide stronger evidence of benefit for early use of single-dose intravenous bolus salbutamol in children with acute severe exacerbations of asthma. Methods: Randomized, double-blind, placebo-controlled trial of 84 children with acute severe asthma who presented to the emergency department of the Children's Hospital at Westmead. After clinical evaluation, patients who had severe asthma were given high-dose inhaled salbutamol and had an intravenous cannula inserted. Additional treatment consisted of intravenous methylprednisolone (1 mg/kg), oxygen (6 L/min via mask if Sao(2) was <93%). Patients were then randomized to receive an intravenous infusion of either 15 &mgr;g/kg salbutamol or saline, with clinical progress assessed hourly for 2 hrs. All patients were admitted to the hospital and clinically monitored for the proceeding 2-24 hrs, with inhaled salbutamol treatment administered in accord with the hospital's protocol. RESULTS: The intravenous salbutamol group (n = 50) demonstrated earlier clinical improvement, with earlier reduction in oxygen therapy and reduced need for ongoing inhaled salbutamol therapy by the end of phase 1 compared with the control group (n = 34). Patients in the intravenous salbutamol group were ready for discharge from the emergency department 3.7 hrs earlier than those in the control group and were ready for discharge from the hospital 9.7 hrs earlier than controls. No significant side effects were found in either group. CONCLUSION: A single-dose intravenous salbutamol bolus of 15 &mgr;g/kg administered over 10 mins in the initial treatment of children with acute severe asthma in the emergency department has the potential to shorten the duration of severe attacks and reduce overall requirements for inhaled salbutamol maintenance.
RESUMO
In 1998, we conducted the first national survey of urology residents to evaluate Canadian training programs and other aspects related to the future practice of urology. The survey, a 7-page questionnaire, examined the educational learning needs of the trainees. Of 70 residents surveyed, 41 responded (response rate 60%). Topic areas in which the respondents felt comfortable included uro-oncology, and surgery of the prostate, kidney, and bladder. They were less comfortable with management of incontinence and infertility. In-training evaluation was thought to be an important activity that was well done by the training programs. A large majority (81%) expressed interest in elective rotations which they indicated should last 3 to 4 months. They suggested that research rotations be available, but not mandatory. There was strong support for the concept of a national examination preparation course. Almost half of the respondents indicated that American board examinations in urology were important in that it allowed them a choice between Canada and the United States. These results will be of use to those involved in the training of Canada's future urologists.
RESUMO
AIM: To determine the current use of beta2-agonists, in particular salbutamol, for the management of acute asthma in children in emergency departments throughout Australia and New Zealand. METHODS: A cross-sectional survey using a questionnaire that sought to determine the current use of salbutamol and any adverse drug reactions in paediatric emergency departments. RESULTS: Out of 37 hospitals eligible as paediatric emergency departments, 33 (89.1%) responded to the survey, 54.5% having guidelines for the management of acute asthma. Of the paediatric emergency departments surveyed, 45.5% used metered-dose inhaler spacer combination in the treatment of mild to moderate asthma. All paediatric emergency departments used nebulized salbutamol for acute severe asthma. In addition, 85% of paediatric emergency departments used continuous-infusion intravenous salbutamol in unresponsive patients, 63.6% administering a single-dose intravenous salbutamol bolus before commencing the infusion. District paediatric emergency departments were more likely to treat with continuous-infusion intravenous salbutamol outside of the intensive care unit. Clinical unresponsiveness to inhaled salbutamol and clinical improvement were the reported criteria in all paediatric emergency departments for the use and cessation of intravenous salbutamol. Adverse drug reactions were common: tremor (90%), hypokalaemia (45.5%) and supraventricular tachycardia (21%), particularly if continuous-infusion intravenous salbutamol administered. Eight deaths from asthma were reported, none being related to adverse drug reactions. CONCLUSION: We report a wide variation of salbutamol use in paediatric emergency departments and a high prevalence of type A adverse drug reactions when continuous-infusion intravenous salbutamol therapy was administered. More evidence is needed on the clinical significance of the adverse effects reported in this study and optimal doses for the safe use of continuous-infusion intravenous salbutamol therapy in paediatric emergency departments.
