Longitudinal fatigue data in children suffering from traumatic brain injury (TBI) are lacking.
To examine the effects of time postinjury (6-12 months) and injury severity on fatigue after childhood ...TBI. Secondarily, we compared fatigue 12 months postinjury against published control data.
Three tertiary children's hospitals across Australia (n = 1) and Canada (n = 2).
Parents (n = 109) of children (mean M = 9.9 years at injury; range, 1.0-16.9 years) admitted to one of 3 participating hospitals with mild (n = 69) or moderate/severe (n = 37) TBI.
Longitudinal prospective study.
Primary: Pediatric Quality of Life Multidimensional Fatigue Scale (total, general, sleep/rest, and cognitive), rated by parents 6 and 12 months postinjury. Secondary: Pediatric Injury Functional Outcome Scale (fatigue and sleep items, rated on recruitment and 6 and 12 months postinjury). Demographic and children data were collected at recruitment.
Mixed-models analysis demonstrated nonsignificant effects of time (6 vs 12 months postinjury) on multidimensional fatigue scores. Cognitive fatigue worsened over time. Moderate/severe TBI was associated with worse fatigue 12 months postinjury (general, P = .03; cognitive, P = .02). Across all severities, fatigue 12 months postinjury was significantly worse compared with control data (total fatigue, P < .001; all domains, all Ps < .025).
Fatigue remains significant at 12 months since injury, particularly for those with moderate/severe TBI.
Subacute Sclerosing Panencephalitis (SSPE) is a fatal progressive neurological disorder following measles infection.
Cases were collated from Paediatric Neurology centres in the UK over 24 months ...from 2017 to 2019 and represent all cases referred to the National Viral Reference Department (VRD). Diagnosis was established with detection of a raised measles index, demonstrating intrathecal measles antibody production.
Six children presented with SSPE over two years, with median age five years (range 2–7 years) and median latency period three years (range 2–6 years). The majority were exposed to measles during infancy. Atypical features were common, including visual impairment, focal and generalised tonic-clonic seizures, headache, vomiting and movement disorders. EEG demonstrated typical features in five cases, though not always at presentation. Initial MRI was normal in four cases, with two showing focal and widespread white matter changes. Antiviral and immunomodulatory treatment led to minimal or no improvement. All progressed to cognitive regression, seizures and neurological decline within six months.
These cases demonstrate the highest incidence of SSPE in the UK since 2000, all progressing to acute fulminant disease, following younger age of onset, short latency period and atypical presentations. Recent global surges in measles cases raise the importance of clinician awareness of SSPE as a potential diagnosis in children with neurological regression. Herd immunity remains the key protective mechanism for infants and groups that cannot be vaccinated. Health care providers, educators and governments must ensure resources continue to target effective education and access to immunisation programmes, the only means to combat this devastating and fatal condition.
•SSPE is a lethal progressive neurological disorder that follows measles infection.•We present the most significant UK cohort in the last 20 years.•Cases were younger than previously described cohorts, with short latency periods.•Acute fulminant course occurred in all, with atypical symptoms and investigations.•The majority were vaccinated, but exposed to measles before the scheduled MMR dose.
As part of the series on maternal, neonatal, and child health in sub-Saharan Africa, Robert Black and colleagues estimated mortality reduction for 42 countries and conclude that the use of local data ...is needed to prioritize the most effective mix of interventions.

Aim
To correlate the North Star Ambulatory Assessment (NSAA) and timed rise from floor (TRF) recorded at age of expected peak with age at loss of ambulation (LOA) in Duchenne muscular dystrophy ...(DMD).
Method
Male children with DMD enrolled in the UK North Start Network database were included according to the following criteria: follow‐up longer than 3 years, one NSAA record between 6 years and 7 years 6 months (baseline), at least one visit when older than 8 years. Data about corticosteroid treatment, LOA, genotype, NSAA, and TRF were analysed. Age at LOA among the different groups based on NSAA and TRF was determined by log‐rank tests. Cox proportional hazard models were used for multivariable analysis.
Results
A total of 293 patients from 13 different centres were included. Mean (SD) age at first and last visit was 5 years 6 months (1 year 2 months) and 12 years 8 months (2 years 11 months) (median follow‐up 7 years 4 months). Higher NSAA and lower TRF at baseline were associated with older age at LOA (p<0.001). Patients scoring NSAA 32 to 34 had a probability of 0.61 of being ambulant when older than 13 years compared with 0.34 for those scoring 26 to 31. In multivariable analysis, NSAA, TRF, and corticosteroid daily regimen (vs intermittent) were all independently associated with outcome (p=0.01).
Interpretation
Higher functional abilities at peak are associated with older age at LOA in DMD. This information is important for counselling families. These baseline measures should also be considered when designing clinical trials.
In Duchenne muscular dystrophy, we lack data linking early motor abilities to loss of ambulation (LOA). In this study, we investigated the relationship between two functional scores (i.e. North Star Ambulatory Assessment NSAA and Timed Rise from Floor TRF) recorded at the time of expected peak and LOA. Both higher NSAA scores and lower TRF were associated with later age at LOA. This information is important for counselling families and should also be considered when designing clinical trials.
Objective To investigate the risk factors of empyema after acute viral infection and to clarify the hypothesized association(s) between empyema and some viruses and/or the use of nonsteroidal ...anti-inflammatory drugs (NSAIDs). Study design A case-control study was conducted in 15 centers. Cases and controls were enrolled for a source population of children 3-15 years of age with acute viral infections between 2006 and 2009. Results Among 215 empyemas, 83 cases (children with empyema and acute viral infection within the 15 preceding days) were included, and 83 controls (children with acute viral infection) were matched to cases. Considering the intake of any drug within 72 hours after acute viral infection onset and at least 6 consecutive days of antibiotic use and at least 1 day of NSAIDs exposure, the multivariable analysis retained an increased risk of empyema associated with NSAIDs exposure (aOR 2.79, 95% CI 1.4-5.58, P = .004), and a decreased risk associated with antibiotic use (aOR 0.32, 95% CI 0.11-0.97, P = .04). The risk of empyema associated with NSAIDs exposure was greater for children not prescribed an antibiotic and antibiotic intake diminished that risk for children given NSAIDs. Conclusions NSAIDs use during acute viral infection is associated with an increased risk of empyema in children, and antibiotics are associated with a decreased risk. The presence of antibiotic-NSAIDs interaction with this risk is suggested. These findings suggest that NSAIDs should not be recommended as a first-line antipyretic treatment during acute viral infections in children.
ObjectiveTo describe age and time at key stages in the Duchenne muscular dystrophy (DMD) prediagnosis pathway at selected centres to identify opportunities for service improvement.DesignA multicentre ...retrospective national audit.SettingNine tertiary neuromuscular centres across the UK and Ireland. A prior single-centre UK audit of 20 patients with no DMD family history provided benchmark criteria.PatientsPatients with a definitive diagnosis of DMD documented within 3 years prior to December 2018 (n=122).Main outcome measuresMean age (months) at four key stages in the DMD diagnostic pathway and mean time (months) of presentational and diagnostic delay, and time from first reported symptoms to definitive diagnosis. Type of symptoms was also recorded.ResultsOverall, mean age at definitive diagnosis, age at first engagement with healthcare professional (HCP) and age at first reported symptoms were 53.9±29.7, 49.9±28.9 and 36.4±26.8 months, respectively. The presentational delay and time to diagnosis were 21.1 (±21.1) and 4.6 (±7.9) months, respectively. The mean time from first reported symptoms to definitive diagnosis was 24.2±20.9. The percentages of patients with motor and/or non-motor symptoms recorded were 88% (n=106/121) and 47% (n=57/121), respectively.ConclusionsMajority of data mirrored the benchmark audit. However, while the time to diagnosis was shorter, a presentational delay was observed. Failure to recognise early symptoms of DMD could be a contributing factor and represents an unmet need in the diagnosis pathway. Methods determining how to improve this need to be explored.
Drug repurposing could provide novel treatment options for Duchenne muscular dystrophy. Because tamoxifen—an oestrogen receptor regulator—reduced signs of muscular pathology in a Duchenne muscular ...dystrophy mouse model, we aimed to assess the safety and efficacy of tamoxifen in humans as an adjunct to corticosteroid therapy over a period of 48 weeks.
We did a multicentre, randomised, double-blind, placebo-controlled, phase 3 trial at 12 study centres in seven European countries. We enrolled ambulant boys aged 6·5–12·0 years with a genetically confirmed diagnosis of Duchenne muscular dystrophy and who were on stable corticosteroid treatment for more than 6 months. Exclusion criteria included ophthalmological disorders, including cataracts, and haematological disorders. We randomly assigned (1:1) participants using an online randomisation tool to either 20 mg tamoxifen orally per day or matched placebo, stratified by centre and corticosteroid intake. Participants, caregivers, and clinical investigators were masked to treatment assignments. Tamoxifen was taken in addition to standard care with corticosteroids, and participants attended study visits for examinations every 12 weeks. The primary efficacy outcome was the change from baseline to week 48 in scores on the D1 domain of the Motor Function Measure in the intention-to-treat population (defined as all patients who fulfilled the inclusion criteria and began treatment). This study is registered with ClinicalTrials.gov (NCT03354039) and is completed.
Between May 24, 2018, and Oct 14, 2020, 95 boys were screened for inclusion, and 82 met inclusion criteria and were initially enrolled into the study. Three boys were excluded after initial screening due to cataract diagnosis or revoked consent directly after screening, but before randomisation. A further boy assigned to the placebo group did not begin treatment. Therefore, 40 individuals assigned tamoxifen and 38 allocated placebo were included in the intention-to-treat population. The primary efficacy outcome did not differ significantly between tamoxifen (–3·05%, 95% CI –7·02 to 0·91) and placebo (–6·15%, –9·19 to –3·11; 2·90% difference, –3·02 to 8·82, p=0·33). Severe adverse events occurred in two participants: one participant who received tamoxifen had a fall, and one who received placebo suffered a panic attack. No deaths or life-threatening serious adverse events occurred. Viral infections were the most common adverse events.
Tamoxifen was safe and well tolerated, but no difference between groups was reported for the primary efficacy endpoint. Slower disease progression, defined by loss of motor function over time, was indicated in the tamoxifen group compared with the placebo group, but differences in outcome measures were neither clinically nor statistically significant. Currently, we cannot recommend the use of tamoxifen in daily clinical practice as a treatment option for boys with Duchenne muscular dystrophy due to insufficient clinical evidence.

Ischemic spinal cord infarction is rare in the paediatric population, and when it does occur, it is usually associated with traumatic injury. Other potential causes include congenital cardiovascular ...malformations, cerebellar herniation, thromboembolic disease and infection. Magnetic resonance imaging (MRI) findings can be subtle in the early evaluation of such patients. The outcome is variable and depends on the level and extent of the spinal cord infarct and subsequent rehabilitation. Here, we present two cases of ischemic spinal cord infarction in children.
Abstract Merosin deficient congenital muscular dystrophy 1A (MDC1A) results from mutations in the LAMA2 gene. We report 51 patients with MDC1A and examine the relationship between degree of merosin ...expression, genotype and clinical features. Thirty-three patients had absence of merosin and 13 showed some residual merosin. Compared to the residual merosin group, patients with absent merosin had an earlier presentation (<7 days) ( P = 0.0073), were more likely to lack independent ambulation ( P = 0.0215), or require enteral feeding ( P = 0.0099) and ventilatory support ( P = 0.0354). We identified 33 novel LAMA2 mutations; these were distributed throughout the gene in patients with absent merosin, with minor clusters in exon 27, 14, 25 and 26 (55% of mutations). Patients with residual merosin often carried at least one splice site mutation and less frequently frameshift mutations. This large study identified novel LAMA2 mutations and highlights the role of immunohistochemical studies for merosin status in predicting clinical severity of MDC1A.
