Postoperative pain and pain management following selective dorsal rhizotomy.

Cerebral Palsy

Selective dorsal rhizotomy (SDR) is a neurosurgical procedure that reduces lower limb spasticity, performed in some children with spastic diplegic cerebral palsy. Effective pain management after SDR is essential for early rehabilitation. This study aimed to describe the anaesthetic and early pain management, pain and adverse events in children following SDR.

This was a retrospective cohort study. Participants were all children who underwent SDR at a single Australian tertiary hospital between 2010 and 2020. Electronic medical records of all children identified were reviewed. Data collected included demographic and clinical data (pain scores, key clinical outcomes, adverse events and side effects) and medications used during anaesthesia and postoperative recovery.

22 children (n=8, 36% female) had SDR. The mean (SD) age at surgery was 6 years and 6 months (1 year and 4 months). Common intraoperative medications used were remifentanil (100%), ketamine (95%), paracetamol (91%) and sevoflurane (86%). Postoperatively, all children were prescribed opioid nurse-controlled analgesia (morphine, 36%; fentanyl, 36%; and oxycodone, 18%) and concomitant ketamine infusion. Opioid doses were maximal on the day after surgery. The mean (SD) daily average pain score (Wong-Baker FACES scale) on the day after surgery was 1.4 (0.9), decreasing to 1.0 (0.5) on postoperative day 6 (POD6). Children first attended the physiotherapy gym on median day 7 (POD8, range 7-8). Most children experienced mild side effects or adverse events that were managed conservatively. Common side effects included constipation (n=19), nausea and vomiting (n=18), and pruritus (n=14). No patient required return to theatre, ICU admission or prolonged inpatient stay.

Most children achieve good pain management following SDR with opioid and ketamine infusions. Adverse events, while common, are typically mild and managed with medication or therapy. This information can be used as a baseline to improve postoperative care and to support families' understanding of SDR before surgery.

Temporal Trends in Severe Brain Injury and Associated Outcomes in Very Preterm Infants.

Cerebral Palsy

Severe brain injury (SBI), including severe intraventricular haemorrhage (sIVH) and cystic periventricular leukomalacia, poses significant challenges for preterm infants, yet recent data and trends are limited.

Analyses were conducted using the Australian and New Zealand Neonatal Network data on preterm infants born <32 weeks' gestation admitted at Monash Children's Hospital, Australia, from January 2014 to April 2021. The occurrence and trends of SBI and sIVH among preterm infants, along with the rates and trends of death and neurodevelopmental impairment (NDI) in SBI infants were assessed.

Of 1,609 preterm infants, 6.7% had SBI, and 5.6% exhibited sIVH. A total of 37.6% of infants with SBI did not survive to discharge, with 92% of these deaths occurring following redirection of clinical care. Cerebral palsy was diagnosed in 65.2% of SBI survivors, while 86.4% of SBI survivors experienced NDI. No statistically significant differences were observed in the temporal trends of SBI (adjusted OR [95% CI] 1.08 [0.97-1.20]; p = 0.13) or sIVH (adjusted OR [95% CI] 1.09 [0.97-1.21]; p = 0.11). Similarly, there was no statistically significant difference noted in the temporal trend of the composite outcome, which included death or NDI among infants with SBI (adjusted OR [95% CI] 0.90 [0.53-1.53]; p = 0.71).

Neither the rates of SBI nor its associated composite outcome of death or NDI improved over time. A notable proportion of preterm infants with SBI faced redirection of care and subsequent mortality, while most survivors exhibited adverse neurodevelopmental challenges. The development of better therapeutic interventions is imperative to improve outcomes for these vulnerable infants.

Neonatal magnesium sulphate for neuroprotection: A systematic review and meta-analysis.

Cerebral Palsy

To review the evidence of the effects of neonatal magnesium sulphate for neuroprotection in perinatal asphyxia and hypoxic-ischaemic encephalopathy (HIE).

This was a systematic review of randomized controlled trials (RCTs) (with meta-analysis) and non-RCTs assessing magnesium sulphate for treating perinatal asphyxia and HIE at 35 weeks or more gestation (primary outcomes: neonatal death and death or long-term major neurodevelopmental disability).

Twenty-five RCTs (2099 infants) and four non-RCTs (871 infants) were included, 23 in low- and middle-income countries (LMICs). In RCTs, reductions in neonatal death with magnesium sulphate versus placebo or no treatment (risk ratio [RR] = 0.68; 95% confidence interval [CI] = 0.53-0.86; 13 RCTs), and magnesium sulphate with melatonin versus melatonin alone (RR = 0.74; 95% CI = 0.58-0.95; one RCT) were observed. No difference in neonatal death was seen for magnesium sulphate with therapeutic hypothermia versus therapeutic hypothermia alone (RR = 0.66, 95% CI = 0.34-1.26; three RCTs), or magnesium sulphate versus phenobarbital (RR = 3.00; 95% CI = 0.86-10.46; one RCT). No reduction in death or long-term neurodevelopmental disability (RR = 0.52; 95% CI = 0.14-1.89; one RCT) but reductions in several short-term adverse outcomes were observed with magnesium sulphate. Evidence was low- to very-low certainty because of risk of bias and imprecision.

Given the uncertainty of the current evidence, further robust neonatal magnesium sulphate research is justified. This may include high-quality studies to determine stand-alone effects in LMICs and effects with and after therapeutic hypothermia in high-income countries.

A preliminary study on the spasticity reduction of quadriceps after selective dorsal rhizotomy in pediatric cases of spastic cerebral palsy.

(Cerebral palsy[MeSH Major

This study aimed to evaluate the potential alleviation of quadriceps spasticity in children diagnosed with spastic cerebral palsy (CP) following selective dorsal rhizotomy (SDR).

A retrospective study was conducted on children suffering from spastic CP who underwent SDR at the Department of Neurosurgery, Shanghai Children's Hospital, from July 2018 to September 2020. Inclusion criteria comprised children exhibiting quadriceps spasticity exceeding modified Ashworth Scale grade 2. Muscle tone and motor function were assessed before the operation, at short-term follow-up and at the last follow-up after SDR. Additionally, intraoperative neurophysiological monitoring data were reviewed.

The study comprised 20 eligible cases, where, prior to surgery, 35 quadriceps muscles exhibited spasticity exceeding modified Ashworth Scale grade 2. Following short-term and mid-term follow-up, specifically an average duration of 11 ± 2 days and 1511 ± 210 days after SDR, it was observed that muscle tension in adductors, hamstrings, gastrocnemius, and soleus decreased significantly. This reduction was accompanied by a decrease in quadriceps muscle tone in 24 out of 35 muscles (68.6%). Furthermore, the study found that intraoperative electrophysiological parameters can predict postoperative spasticity relief in the quadriceps. The triggered electromyographic (EMG) output of the transected sensory root/rootlets after single-pulse stimulation revealed that the higher the EMG amplitudes in quadriceps, the greater the likelihood of postoperative decrease in quadriceps muscle tension.

SDR demonstrates the potential to reduce muscle spasticity in lower extremities in children diagnosed with CP, including a notable impact on quadriceps spasticity even they are not targeted in SDR. The utilization of intraoperative neurophysiological monitoring data enhances the predictability of quadriceps spasticity reduction following SDR.

Does somatosensory discrimination therapy alter sensorimotor upper limb function differently compared to motor therapy in children and adolescents with unilateral cerebral palsy: study protocol for a randomized controlled trial.

Cerebral Palsy

ClinicalTrials.gov (NCT06006065). Registered on August 8, 2023.

A parallel group, evaluator-blinded, phase-II, single-center RCT will be conducted for which 50 children and adolescents with uCP, aged 7 to 15 years, will be recruited. Participants will be randomized to receive 3 weekly sessions of 45 minutes of either somatosensory discrimination therapy or upper limb motor therapy for a period of 8 weeks. Stratification will be performed based on age, manual ability, and severity of tactile impairment at baseline. Sensorimotor upper limb function will be evaluated at baseline, immediately after the intervention and after 6 months follow-up. The primary outcome measure will be bimanual performance as measured with the Assisting Hand Assessment. Secondary outcomes include a comprehensive test battery to objectify somatosensory function and measures of bimanual coordination, unimanual motor function, and goal attainment. Brain imaging will be performed at baseline to investigate structural brain lesion characteristics and structural connectivity of the white matter tracts.

This protocol describes the design of an RCT comparing the effectiveness of somatosensory discrimination therapy and dose-matched motor therapy to improve sensorimotor upper limb function in children and adolescents with uCP. The results of this study may aid in the selection of the most effective upper limb therapy, specifically for children and adolescents with tactile impairments.

Neurosensory, cognitive and academic outcomes at 8 years in children born 22-23 weeks' gestation compared with more mature births.

Cerebral Palsy

Despite providing intensive care to more infants born <24 weeks' gestation, data on school-age outcomes, critical for counselling and decision-making, are sparse.

To compare major neurosensory, cognitive and academic impairment among school-aged children born extremely preterm at 22-23 weeks' gestation (EP22-23) with those born 24-25 weeks (EP24-25), 26-27 weeks (EP26-27) and term (≥37 weeks).

At 8 years, major neurosensory disability (any of moderate/severe cerebral palsy, IQ <-2 SD relative to controls, blindness or deafness), motor, cognitive and academic impairment, executive dysfunction and poor health utility. Risk ratios (RRs) and risk differences between EP22-23 (reference) and other gestational age groups were estimated using generalised linear models, adjusted for era of birth, social risk and multiple birth.

The risk of major neurosensory disability was higher for EP22-23 (n=21) than more mature groups (168 EP24-25; 312 EP26-27; 576 term), with increasing magnitude of difference as the gestation increased (adjusted RR (95% CI) compared with EP24-25: 1.39 (0.70 to 2.76), p=0.35; EP26-27: 1.85 (0.95 to 3.61), p=0.07; term: 13.9 (5.75 to 33.7), p<0.001). Similar trends were seen with other outcomes. Two-thirds of EP22-23 survivors were free of major neurosensory disability.

Although children born EP22-23 experienced higher rates of disability and impairment at 8 years than children born more maturely, many were free of major neurosensory disability. These data support providing active care to infants born EP22-23.

Speech and communication classification of children with cerebral palsy: Novice rater agreement and clinical utility.

Cerebral Palsy

To examine novice inter-rater agreement and clinical utility perspectives for speech and communication classification of children with cerebral palsy (CP).

Twenty-one clinicians (speech-language pathologists [SLPs] n = 11; physiotherapists [PTs] n = 5; occupational therapists [OTs] n = 5) novice to the Viking Speech Scale (VSS), Functional Communication Classification System (FCCS), and Communication Function Classification System (CFCS) rated eight unfamiliar children with CP (8-16 years) following classification orientation. Inter-rater agreement was examined between (a) novices, (b) novice SLPs vs. PTs and OTs, and (c) novice vs. expert (kappa statistics). Utility perceptions were scored regarding classification terminology, ease of use, assistive decision-making resources, and construct validity and were analysed using Kruskal-Wallis H-tests.

Rating agreement between novices was substantial (VSS, k = 0.72, 95% CI [0.53-0.92]) to moderate (FCCS, k = 0.44, 95% CI [0.23-0.65]; CFCS, k = 0.45, 95% CI [0.18-0.71]), and almost perfect between novice and expert ratings (VSS, kw = 0.89, 95% CI [0.86-0.92]; FCCS, kw = 0.89, 95% CI [0.86-0.92]; CFCS, kw = 0.86, 95% CI [0.82-0.91]). Statistically significant differences, presented highest to lowest, were found for clinical utility: terminology (VSS, FCCS, CFCS; p = 0.02), assistive decision-making resources (FCCS, VSS, CFCS; p = 0.009), and construct validity (FCCS, CFCS, VSS; p < 0.001).

Novice raters achieved substantial agreement for speech classification, supporting utilisation in clinical, research, and CP register activities. Orientation to communication classification constructs, content, and instructions is recommended for novice raters.

A pilot study proposing an algorithm for pubertal induction in cerebral palsy.

Cerebral Palsy

To explore delayed puberty in cerebral palsy (CP) and to test the acceptability of an interventional puberty induction algorithm.

A two phase cohort study in children and adolescents diagnosed with CP who have delayed puberty. Phase 1: Retrospective review of clinical records and interviews with patients who have been treated with sex-steroids and Phase 2: Prospective interventional trial of pubertal induction with a proposed algorithm of transdermal testosterone (males) or oestrogen (females). Phase 1 examined experiences with sex-steroid treatment. Phase 2 collected data on height adjusted bone mineral density (BMAD), fractures, adverse effects, mobility and quality of life over two years during the induction.

Phase 1, treatment was well tolerated in 11/20 treated with sex-steroids; phase 2, using the proposed induction algorithm, 7/10 treated reached Tanner stage 3 by nine months. One participant reached Tanner stage 5 in 24 months. Mean change in BMAD Z-scores was +0.27 % (SD 0.002) in those who could be scanned by dual-energy X-ray absorptiometry (DXA).

Delayed puberty may be diagnosed late. Treatment was beneficial and well tolerated, suggesting all patients with severe pubertal delay or arrest should be considered for sex hormone supplementation.

Can RESPiratory hospital Admissions in children with cerebral palsy be reduced? A feasibility randomised Controlled Trial pilot study protocol (RESP-ACT).

Cerebral Palsy

Australian New Zealand Clinical Trials Registry (ACTRN12620000114943).

Mixed-method feasibility pilot randomised controlled trial with economic analysis. Twenty children with CP aged 0-12 years who are at risk of respiratory disease will be followed up for 1 year. All children will receive baseline assessments for comparison. The control group will receive usual care from their treating teams. The intervention group will receive comprehensive assessments from physiotherapy, speech pathology and respiratory medicine. An individualised investigation and treatment plan will then be made. Participants in both groups will complete fortnightly patient-reported outcome surveys to assess symptoms and health service use. Analysis will include assessments of acceptability through qualitative interviews, implementation by ability to recruit, randomise and retain, practicality including costs of intervention and hospitalisation, and explore efficacy through quality-of-life surveys and decreased health service use for respiratory-related symptoms.
