Global trends and decision-making in the management of arachnoid cysts.

OBJECTIVE: In pediatric patients, middle cranial fossa (MCF) arachnoid cysts are often discovered incidentally on imaging in asymptomatic patients during workup for other indications. This study aims to describe current management gestalt and threshold for surgical intervention by surveying an international cohort of neurosurgeons. METHODS: A web-based survey was circulated via email list of attendants of the 2019 Canadian Pediatric Neurosurgery Study Group (CPNSG) and International Society of Pediatric Neurosurgery (ISPN) mailing list. The survey consisted of 8 clinical scenarios involving patients with MCF arachnoid cysts. Demographic variables of respondents and their decisions regarding management for each scenario were analyzed using R computing software. RESULTS: A total of 107 respondents were included. Cysts in asymptomatic patients (92%), younger age at diagnosis (81%), and presence of a mild learning delay were predominantly managed non-surgically (80.7 ± 9.4%). Patients with cyst enlargement, headaches, new seizures, or hemorrhage were divided between non-surgical (55.8 ± 3.3%) and surgical (44.2 ± 2.9%) management. Patients with contralateral hemiparesis were treated predominantly surgically (67%). For both Galassi I and II, papilledema was favored as the primary indication for surgical intervention in 54% of patients. Those inclined to surgery (n = 17) were more likely to practice and train outside North America compared to those not pro-surgical (adjusted P = 0.092). CONCLUSION: Incidental MCF arachnoid cysts in asymptomatic patients and younger age of diagnosis are predominantly managed non-surgically. Mild learning delay was not considered an indication to intervene. In contrast, radiological progression, hemorrhagic evolution, or non-focal neurological deficits lead to uncertainty in management, while focal neurological deficits and papilledema with MCF cysts were favored to be intervened surgically. Among the provider level factors, only location of training and practice trended towards a pro-surgery approach.

Virtual psychoeducation for improvement of pain catastrophizing in pediatric presurgical patients and caregivers: a proof-of-concept study.

PURPOSE: Pain catastrophizing (PC) is the tendency to magnify the threat value of pain sensations and is associated with greater postsurgical pain intensity, functional disability, and pain chronicity. Higher parental PC predicts higher chronic postsurgical pain in youth. Treating PC in caregivers and youth prior to surgery may improve recovery and surgical outcomes. We developed and evaluated a psychoeducational workshop addressing PC for presurgical youth and their parents/caregivers. We hypothesized that parent/caregiver and youth PC scores would decrease over time. We also explored preintervention levels of youth anxiety and depression as moderators of outcome. METHODS: Youth (n = 43) and caregivers (n = 41) attended a virtual, group-based single-session intervention (SSI). Single-session intervention content addressed pain neuroscience, PC, and adaptive coping strategies for managing pain and PC drawn from cognitive-behavioural, acceptance and commitment, and dialectical behaviour therapy approaches. Participants completed questionnaires assessing PC at preintervention, postintervention, and two weeks postsurgery. Youth mood and anxiety were assessed at preintervention. RESULTS: Caregiver PC scores decreased from pre- to postintervention (P = 0.006), and this was maintained at postsurgery (P = 0.002). Youth PC scores decreased from preintervention to postsurgery, but only for those with higher preintervention anxiety (P = 0.01). CONCLUSION: Our results provide proof-of-concept support for a virtual SSI targeting caregivers and youth PC during the perioperative period. The present findings highlight the possible need to screen presurgical candidates for symptoms of anxiety. Replication with larger and more diverse samples, and a more robust design are warranted.

RéSUMé: OBJECTIF: Le terme de dramatisation de la douleur décrit la tendance à amplifier la valeur de menace des sensations de douleur et est associée à une plus grande intensité de la douleur postopératoire, à une incapacité fonctionnelle et à une chronicité de la douleur. Une dramatisation parentale plus élevée de la douleur prédit une douleur postopératoire chronique plus élevée chez les jeunes. Le traitement de la dramatisation de la douleur chez les soignant·es et les jeunes avant la chirurgie peut améliorer le rétablissement et les devenirs chirurgicaux. Nous avons mis au point et évalué un atelier psychoéducatif sur la dramatisation de la douleur destiné aux jeunes en période préchirurgicale et à leurs parents/soignant·es. Nous avons émis l'hypothèse que les scores de dramatisation de la douleur des parents/soignant·es et des jeunes diminueraient avec le temps. Nous avons également exploré les niveaux d'anxiété et de dépression des jeunes avant l'intervention en tant qu'éléments modérateurs des résultats. MéTHODE: Des jeunes (n = 43) et les personnes en prenant soin (n = 41) ont participé à une seule intervention virtuelle en groupe. Le contenu de l'intervention unique portait sur les neurosciences de la douleur, la dramatisation de la douleur et les stratégies d'adaptation pour la prise en charge de la douleur et la dramatisation de la douleur tirées des approches cognitivo-comportementales, d'acceptation et d'engagement, et de thérapie comportementale dialectique. Les participant·es ont rempli des questionnaires évaluant la dramatisation de la douleur avant l'intervention, après l'intervention et deux semaines après la chirurgie. L'humeur et l'anxiété des jeunes ont été évaluées avant l'intervention. RéSULTATS: Les scores de dramatisation de la douleur des soignant·es ont diminué de la période précédant à la période suivant l'intervention (P = 0,006), et cela s'est maintenu après la chirurgie (P = 0,002). Les scores de dramatisation de la douleur des jeunes ont diminué de la période précédant l'intervention à la période postchirurgie, mais seulement chez les jeunes présentant une anxiété pré-intervention plus élevée (P = 0,01). CONCLUSION: Nos résultats appuient la preuve de concept pour une intervention virtuelle unique ciblant la dramatisation de la douleur chez les soignant·es et les jeunes en période périopératoire. Ces résultats soulignent la nécessité potentielle de dépister les symptômes d'anxiété chez les candidat·es avant la chirurgie. La réplication avec des échantillons plus grands et plus diversifiés et une conception plus robuste est justifiée.

Physical activity levels, pulmonary function, and MRI in children born extremely preterm: A comparison between children with and without bronchopulmonary dysplasia.

INTRODUCTION: Children with a history of bronchopulmonary dysplasia (BPD) may have lower physical activity levels, but evidence to date is mixed. This study compared physical activity levels between children born extremely preterm with and without history of BPD, and examined their associations with pulmonary magnetic resonance imaging (MRI) and pulmonary function test (PFT) indices. METHODS: This multicentre cross-sectional study included children aged 7-9 years born extremely preterm, with and without BPD. Children wore a pedometer for 1 week, then completed the Physical Activity Questionnaire (PAQ), pulmonary MRI, and PFT. Spearman correlations and multivariable linear regression modeling were performed. RESULTS: Of 45 children, 28 had a history of moderate-severe BPD. There were no differences in any physical activity outcomes by BPD status. Higher average daily step count and higher average daily moderate-to-vigorous physical activity (MVPA) were each correlated with greater forced vital capacity (r = 0.41 and 0.58), greater MRI lung proton density at full expiration (r = 0.42 and 0.49), and lower lung clearance index (r = -0.50 and -0.41). After adjusting for MRI total proton density and BPD status, a 5% increase in forced expiratory volume at 1 s was associated with 738 (95% CI: 208, 1268) more steps per day and 0.1 (0.0, 0.2) more hours of MVPA, respectively. CONCLUSION: School-aged children born extremely preterm have similar physical activity levels to their peers, regardless of history of BPD. MRI and PFT measures suggestive of gas trapping and/or airflow obstruction are associated with lower physical activity levels.

Sleep-disordered breathing symptoms and their association with structural and functional pulmonary changes in children born extremely preterm.

This study aimed to evaluate symptoms of sleep-disordered breathing (SDB) among children born extremely preterm, with and without a history of bronchopulmonary dysplasia (BPD), including associations between sleep and respiratory symptoms, physical activity, pulmonary function, and pulmonary magnetic resonance imaging (MRI). This multi-center cross-sectional study enrolled children aged 7-9 years born extremely preterm with and without BPD. Participants completed the Pediatric Sleep Questionnaire (PSQ), the modified Epworth sleepiness scale, a respiratory symptom questionnaire, pedometer measurements, pulmonary function testing, and pulmonary MRI. Spearman's correlations and univariate and multivariable linear regression modelling were performed. Twenty-eight of 45 children included had a history of moderate-to-severe BPD. The prevalence of sleep-related symptoms was low, with the exception of hyperactivity and inattention. There were no differences in mean (SD) scores on sleep questionnaires in children with and without BPD (PSQ: 0.21 (0.13) vs 0.16 (0.14), p = 0.3; modified Epworth: 2.4 (2.4) vs 1.8 (2.8), p = 0.4). Multiple regression analyses examining difference in sleep scores between groups, adjusting for gestational age and intraventricular hemorrhage, found no statistical difference (p > 0.05). Greater daytime sleepiness was moderately correlated with FEV1%-predicted (r = - 0.52); no other moderate-strong associations were identified.  Conclusions: There was no evidence of clinically important differences in sleep symptoms between children with and without BPD, suggesting that sleep symptoms may be related to prematurity-related factors other than a BPD diagnosis, including airflow limitation. Further research is necessary to explore the relationship between sleep symptoms, airway obstruction, and neurobehavioral symptoms among premature-born children.  Trial registration: NCT02921308. Date of registration: October 3, 2016. What is Known: • Presence of bronchopulmonary dysplasia (BPD) may further contribute to the development of SDB, though its impact is not well-studied. • Premature-born children have a greater risk of lung structural and functional differences, including sleep-disordered breathing (SDB). What is New: • There was no difference in sleep symptoms between children with and without BPD, suggesting that sleep symptoms are related to other prematurity-related factors, such as airflow limitation. • Greater daytime sleepiness was correlated with lower FEV1 in our population, which reflects greater airflow limitation.

Postoperative complications of colectomy and J-pouch with ileostomy versus without ileostomy in children with inflammatory bowel diseases: a systematic review and meta-analysis.

Background: The efficacy of performing a restorative proctocolectomy and J-pouch ileoanal anastomosis without diverting ileostomy in children with inflammatory bowel disease has been a longstanding debate. A systematic review and meta-analysis is presented comparing the occurrence of postoperative complications in children who underwent either the pouch-anal anastomosis (IPAA) with ileostomy (diverted) versus the undiverted procedure. Methods: Records were sourced from CINAHL, CENTRAL, EMBASE and MEDLINE databases. Studies followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and compared postoperative complications in pediatric patients diagnosed with inflammatory diseases aged less than 18 years who underwent J-pouch with ileostomy versus without ileostomy. The primary outcome was the occurrence of postoperative leaks, and the secondary outcomes were presence of postoperative small bowel obstruction (SBO), pouchitis, stricture and fistula complications. A random-effects meta-analysis was used. Results: Twenty-three observational studies in the systematic review were included with 658 patients (83% diverted, 17% undiverted). Pooled estimates showed no difference in occurrence of leaks in children who underwent J-pouch/IPAA with ileostomy versus without (odds ratio (OR) 0.54, 95% confidence interval (CI) 0.17 to 1.64, I2=16%). There was no difference in the occurrence of SBO, pouchitis or strictures in children who underwent J-pouch/IPAA with ileostomy versus without (SBO: OR 2.27, 95% CI 0.52 to 9.92, I2=0%, pouchitis: OR 1.76, 95% CI 0.95 to 3.24, I2=0%, strictures: OR 2.72, 95% CI 0.44 to 16.69, I2=66%). Conclusion: The meta-analysis did not find differences in the occurrence of complications in pediatric patients who underwent the IPAA with ileostomy procedure versus without ileostomy.

Quality of life outcomes in children after surgery for Hirschsprung disease and anorectal malformations: a systematic review and meta-analysis.

Background: No systematic review and meta-analysis to date has examined multiple child and parent-reported social and physical quality of life (QoL) in pediatric populations affected by Hirschsprung's disease (HD) and anorectal malformations (ARM). The objective of this systematic review is to quantitatively summarize the parent-reported and child-reported psychosocial and physical functioning scores of such children. Methods: Records were sourced from the CENTRAL, EMBASE, and MEDLINE databases. Studies that reported child and parent reported QoL in children with HD and ARM, regardless of surgery intervention, versus children without HD and ARM, were included. The primary outcome was the psychosocial functioning scores, and the secondary outcomes were the presence of postoperative constipation, postoperative obstruction symptoms, fecal incontinence, and enterocolitis. A random effects meta-analysis was used. Results: Twenty-three studies were included in the systematic review, with 11 studies included in the meta-analysis. Totally, 1678 total pediatric patients with HD and ARM underwent surgery vs 392 healthy controls. Pooled parent-reported standardized mean (SM) scores showed better social functioning after surgery (SM 91.79, 95% CI (80.3 to 103.3), I2=0). The pooled standardized mean difference (SMD) showed evidence for parent-reported incontinence but not for constipation in children with HD and ARM after surgery that had a lower mean QoL score compared with the normal population (SMD -1.24 (-1.79 to -0.69), I2=76% and SMD -0.45, 95% CI (-1.12 to 0.21), I2=75%). The pooled prevalence of child-reported constipation was 22% (95% CI (16% to 28%), I2=0%). The pooled prevalence of parent-reported postoperative obstruction symptoms was 61% (95% CI (41% to 81%), I2=41%). Conclusion: The results demonstrate better social functioning after surgery, lower QoL scores for incontinence versus controls, and remaining constipation and postoperative obstruction symptoms after surgery in children with HD and ARM.

Evaluating the Prognostic Implication of the Collins Histology Scoring System in a Pediatric Eastern Ontario Population With Eosinophilic Esophagitis.

INTRODUCTION: Collins et al developed a histology scoring system (EoE HSS) to assess multiple pathologic features. The aim of this study is to identify if the EoE HSS can better detect endoscopic and symptom improvement vs the Peak Eosinophilic Count (PEC). METHODS: A retrospective chart review was performed for patients during 2014-2016. All patients ≤18 years old with a diagnosis of EoE and whose records included initial and follow-up upper gastrointestinal endoscopies were included. Severity and extent of endoscopic features were scored using 8 parameters, from normal to maximum change for each location of the esophageal biopsy. RESULTS: Forty patients with EoE were included in the study, of which 35 (87.5%) patients demonstrated symptom and 25 (62.5%) endoscopic improvement at the time of follow-up. In the proximal esophagus, the EoE HSS outperformed the change in eosinophil count of the Children's Hospital of Eastern Ontario (CHEO) practice in predicting endoscopic improvement by 16.8% when examining the change in grade and 17.1% when examining the change in stage scores. CONCLUSIONS: At our institution, adoption of the EoE HSS in assessing biopsies of EoE patients might be warranted, compared to the traditional practice. However, a bigger sample size may give a more robust difference in all locations.

Pulmonary Magnetic Resonance Imaging of Ex-Preterm Children with and without Bronchopulmonary Dysplasia.

Rationale: Children born prematurely, particularly those with bronchopulmonary dysplasia, have persisting lung abnormalities requiring longitudinal monitoring. Pulmonary ultrashort echo time magnetic resonance imaging (MRI) measurements may provide sensitive markers of persisting lung abnormalities and have not been evaluated in school-aged children born prematurely. Objectives: To compare pulmonary MRI and pulmonary function test measurements in preterm-born school-aged children with and without bronchopulmonary dysplasia. Methods: Children aged 7-9 years, born extremely preterm, with and without bronchopulmonary dysplasia, were recruited from three centers. Participants underwent pulmonary ultrashort echo time MRI and pulmonary function tests. Primary outcomes included total proton density and proton density at full expiration, measured using MRI. Multiple linear regression analysis was performed, adjusting for gestational age and bronchopulmonary dysplasia. Associations between MRI and pulmonary function were tested. Results: Thirty-five children were included in the primary analysis (24 with bronchopulmonary dysplasia, 11 without); 29 completed pulmonary function tests, of whom 11 (38%) had airflow limitation. Children with bronchopulmonary dysplasia had 44% (95% confidence interval [CI], 10-66%) lower mean total proton density (mean ± standard deviation, 3.6 ± 2.6) than those without (6.1 ± 4.0). Those with bronchopulmonary dysplasia had 25% (95% CI, 3-42%) lower proton density at full expiration than those without. Lower total proton density and proton density at full expiration were moderately correlated with greater residual volume, residual volume/total lung capacity, and lung clearance index (Spearman correlations for total proton density: -0.42, -0.57, and -0.53, respectively. Spearman correlations for proton density at full expiration: -0.28, -0.57, and -0.45, respectively). Conclusions: School-aged preterm-born children with bronchopulmonary dysplasia have parenchymal tissue abnormalities measured using ultrashort MRI proton density, compared with those without. MRI proton density correlated with pulmonary function measures indicative of gas trapping. Clinical trial registered with www.clinicaltrials.gov (NCT02921308).

Evaluation of Fertility Preservation Counseling and Treatments for Female Oncology Patients in an Urban Pediatric Canadian Center.

Purpose: Several international organizations and guidelines have recommended implementation of structured fertility preservation (FP) discussions with patients and their families before initiation of chemotherapy and radiation treatments in children. This study aimed to identify current trends and rates in FP counseling and treatments at a Canadian pediatric tertiary care center. Objectives were to measure guideline adherence for FP counseling at our institution by determining (1) the frequency of FP counseling in pediatric female oncological patients at our institution, (2) the frequency of FP treatment in this study population, and (3) the factors associated with FP pre-treatment counseling. Methods: A retrospective chart review was performed, including all pediatric and adolescent female patients (age <18) seen in consultation by the oncology team. Demographic data, as well as documentation of FP counseling and referral to a reproductive endocrinology and infertility (REI) specialist and subsequent FP treatment were collected. Results: A total of 89 female pediatric patients were included in our study. Forty-two patients received fertility counseling (47.2%; 95% confidence interval [CI] 37.2-57.5). Only 29/42 (69.0%; 95% CI: 54-80.9) received counseling before onset of treatment. A 12/42 (41.4%; 95% CI: 25-59.3) of the patients who received FP counseling were referred to an REI specialist and 11/12 proceeded with FP treatment (37.9%, 95% CI: 22.7-56). Conclusion: This study presents contemporary data on the rates of FP counseling in Canadian pediatric female oncological patients and demonstrates low rates of FP counseling in our patient population.

Pallium Canada's Curriculum Development Model: A Framework to Support Large-Scale Courseware Development and Deployment.

The need to improve access to palliative care across multiple settings and disease groups has been identified. This requires equipping health care professionals from many different professions, including physicians and nurses, among others, with basic palliative care competencies to provide a palliative care approach. Pallium Canada's Curriculum Development Framework supports the development, deployment, and dissemination, on a large scale, of multiple courses targeting health care professionals across multiple settings of care and disease groups. The Framework is made up of eight phases: (1) Concept, (2) Decision, (3) Curriculum Planning, (4) Prototype Development, (5) Piloting, (6) Dissemination, (7) Language and Cultural Adaptation, and (8) Ongoing Maintenance and Updates. Several of these phases include iterative cyclical activities. The framework allows multiple courses to be developed simultaneously, staggered in a production line with each phase and their corresponding activities requiring different levels of resources and stakeholder engagement. The framework has allowed Pallium Canada to develop, launch, and maintain numerous versions of its Learning Essential Approaches to Palliative Care (LEAP) courses concurrently. It leverages existing LEAP courses and curriculum materials to produce new LEAP courses, allowing significant efficiencies and maximizing output. This article describes the framework and its various activities, which we believe could be very useful for other jurisdictions undertaking the work of developing education programs to spread the palliative care approach across multiple settings, specialties, and disease groups.

Comparison of the diagnostic performance of the 2017 ACR TI-RADS guideline to the Kwak guideline in children with thyroid nodules.

BACKGROUND: The Kwak Thyroid Imaging Reporting and Data System (Kwak-TI-RADS) guideline (2011) and American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS) guideline (2017) were developed as ultrasound (US) risk stratification tools for detecting thyroid malignancy in adults. OBJECTIVE: The purpose of this study was to investigate the inter-rater reliability and diagnostic performance of the ACR TI-RADS guideline in the pediatric population and compare it to the Kwak guideline. MATERIALS AND METHODS: This retrospective study comprised 75 children who underwent thyroid US at a tertiary-level pediatric hospital. Three pediatric radiologists and one pediatric radiology fellow graded the US findings using the Kwak-TI-RADS and ACR TI-RADS guidelines. We assessed reliability of radiologists' ratings using percentage inter-rater agreement, and intra-class correlation coefficients (ICC2,1). We assessed area-under-the-receiver-operating-characteristic curve (AUROCC) to compare the discriminative diagnostic ability of the Kwak-TI-RADS and ACR TI-RADS scoring systems against histopathology/cytology, or stability on US over a 2-year follow-up period for cases without tissue diagnosis. RESULTS: The inter-rater agreement was significantly better for the ACR TI-RADS level compared to the Kwak-TI-RADS level (P<0.001) using the percentage pairwise agreement. The ROC curves for assessing the diagnostic performance of the two methods showed no significant difference between the methods. The AUROCCs for the Kwak-TI-RADS and ACR TI-RADS levels were 0.74 (95% confidence interval [CI] 0.67-0.82) and 0.72 (95% CI 0.61-0.82), respectively. CONCLUSION: Both the Kwak-TI-RADS and ACR TI-RADS guidelines provide moderate malignancy risk stratification for thyroid nodules in the pediatric population, with better inter-rater agreement for the ACR TI-RADS guideline. Further work to adjust the recommendations for pediatric patients is necessary.
