Pediatric Headache Experience During the COVID-19 Pandemic.

OBJECTIVE: Headache disorders are exceedingly common in children and adolescents. The association between headaches, emotional stress, and disruptions in daily routines are well established. The goal of this study is to compare the experiences of patients with a preexisting diagnosis of a primary headache disorder in terms of headache frequency and severity, lifestyle techniques for headache prevention, screen use, and mood from before and after the onset of the COVID-19 pandemic. METHODS: Patients evaluated by the Headache Clinic at Children's National Hospital between Summer 2020 and Winter 2021 were enrolled in a patient registry. Patients completed a questionnaire examining changes in headache characteristics and lifestyle factors since the onset of the COVID-19 pandemic. RESULTS: A total of 107 patients completed the survey. Since the pandemic's onset, patients reported decreased physical activity (n = 59, 55%), increased frequency of chronic headaches from 40% (N = 42) to 50% (N = 54), and increased constant daily headaches from 22% (n = 24) to 36% (n = 38). Patients reported worsened anxiety (n = 58, 54%), mood (n = 50, 47%), and workload (n = 49, 46%). Sixty-one percent (n = 65) of patients reported using screens for school for more than 6 hours per day. The majority (n = 67, 63%) of patients indicated that they would prefer attending in-person school, with 14% (n = 15) responding that they preferred online school. CONCLUSION: Since the COVID-19 pandemic's onset, pediatric headache patients have experienced increasing headache frequency, worsening anxiety and mood, decreased physical activity, and increased screen usage. Although this study is limited by sample size and observational design, future population-based studies will further elucidate the impact of this pandemic on pediatric headache.

Perfectly Tired: Perfectionism and Sleep in Adolescents With Chronic Pain.

OBJECTIVE: Conceptual links between perfectionism and chronic pain have been proposed yet minimal empirical data exists. Poor sleep is associated with high levels of perfectionism and is common among youth with chronic pain. This study explores associations between perfectionism and sleep quality in adolescents with chronic pain while considering levels of functional disability. METHODS: Adolescents (ages 12-18) with chronic pain (N = 423) completed baseline measures of self-oriented perfectionism (SOP), socially prescribed perfectionism (SPP), sleep quality, and functional disability as part of routine clinical care at an outpatient chronic pain clinic and a pain rehabilitation day treatment program. Multivariate multiple regression assessed associations between perfectionism (SOP and SPP) and sleep (falling asleep/reinitiating sleep, returning to wakefulness, and going to bed). Two moderation models explored how relations between perfectionism (SOP and SPP) and sleep quality (total score) varied depending on level of functional disability. All analyses controlled for clinic setting. RESULTS: Results indicated SPP was associated with more difficulties across all sleep subdomains in adolescents with chronic pain, while SOP was unrelated to sleep quality. Associations between perfectionism and sleep quality were dependent on functional disability; perfectionism was most strongly associated with worse sleep quality for adolescents with less functional disability. CONCLUSIONS: This study highlights the relationship between perfectionism and sleep quality in adolescents with chronic pain and suggests that perfectionistic youth with less disability are at the greatest risk for sleep problems. Longitudinal research is needed to understand how perfectionism, sleep, and disability interact over time in youth with chronic pain.

Pediatric Migraine and Academics.

PURPOSE OF REVIEW: The purpose of this review is to examine the multitude of factors which may impact learning and academic performance in patients with pediatric migraine. RECENT FINDINGS: A range of associations of varying degree were noted between pediatric migraine and conditions such as ADHD, learning disabilities, sleep disorders, and psychiatric comorbidities with regard to headache pain and school functioning. Recent literature highlights the importance of sleep in relation to headache, mood disorders, and learning in youth and the emerging role of perfectionism. Children with migraine remain at risk for school related and learning difficulties which may be primarily due to pain, due to other medical and psychiatric comorbidities commonly found in this population, or a combination. The relationships are complex and further studies are needed to clearly elucidate the shared biological and environmental pathophysiologic mechanisms.

Topical Review: Perfectionism and Pediatric Chronic Pain: Theoretical Underpinnings, Assessment, and Treatment.

Objective: To use the biopsychosocial model and current literature to clarify conceptual underpinnings between chronic pain and perfectionism in youth, provide recommendations for assessment and treatment of co-existing perfectionism and chronic pain conditions, and suggest a research agenda. Methods: Current literature is used to identify biopsychosocial factors common between pediatric chronic pain and perfectionism, preliminary research findings are presented, and suggestions are made for research that will help inform inclusion and adaptations of assessment tools and interventions to address perfectionism. Results: Biopsychosocial factors that may contribute to the observed relationship between chronic pain and perfectionism seen in many youth are identified. For example, cognitive factors known to be associated with perfectionism (e.g., rumination) may also contribute to pain-related catastrophizing and disability. Biopsychosocial factors may serve as mediating variables between perfectionism and pain-related outcomes among youth with chronic pain and their parents. Conclusions: Research assuming a biopsychosocial perspective is needed to clarify observed links between chronic pain and perfectionism in youth. Findings related to the characterization of perfectionism in pediatric chronic pain will inform how assessment and treatment tools can better identify and address perfectionism.

Barriers to medication adherence and its relationship with outcomes in pediatric dialysis patients.

BACKGROUND: Medication adherence is a major factor determining outcome in children with chronic disease. Children with end-stage renal disease are challenged with requirements for renal replacement therapy in addition to complicated medication regimens. METHODS: We assessed barriers to medication adherence in 22 pediatric patients receiving chronic dialysis [63.6 % hemodialysis (HD), 36.4 % peritoneal dialysis (PD); age 15.9 ± 0.7 years, dialysis vintage 31.6 ± 6.5 months]. Adherence was assessed by a 16-question survey with a maximum score (difficulty) of 64. RESULTS: The overall mean adherence score was 30.9 ± 2.4 (range 16-49; median 27.5). There was a trend for lower adherence scores in patients on HD (27.5 ± 2.9) compared to those on PD (36.8 ± 3.7) (p = 0.06). Compared to HD patients, the mean score/question was significantly higher in PD patients (1.7 ± 0.2 vs. 2.4 ± 0.2, respectively; p = 0.006). Of the 16 questions, HD and PD patients gave a mean response of ≤1.2 for five and zero questions, respectively. Neither gender, age nor dialysis vintage was related to adherence scores. There was also a trend for adherence scores to be higher in females (35.6 ± 3.7) than in males (27.5 ± 2.9) (p = 0.1), but this difference did not reach statistical significance. Markers of mineral bone disease were similar in HD and PD patients. Among all targets in HD and PD patients combined, there was no relationship between adherence scores and number of targets reached (r = -0.09, p = 0.7). CONCLUSION: There are many barriers to medication adherence in pediatric patients receiving dialysis. In our patient group the difficulties were more evident in patients receiving PD than in those receiving HD.

Natural history and risk factors of early respiratory responses to exposure to cotton dust in newly exposed workers.

OBJECTIVE: A prospective study of newly exposed cotton workers was performed to investigate the natural history of respiratory symptoms and lung function changes. METHODS: A total of 157 workers naive to cotton dust exposure were investigated by questionnaire, spirometry, and skin tests. They were examined before employment (baseline) and at the end of the first week, and the first, third, sixth, and 12th month after starting work. Acute airway response was defined as either a cross-first-shift or a cross-week fall in forced expiratory volume in one second (FEV1). The longitudinal change of lung function over the year was also calculated. Five hundred seventy-two personal dust sampling and 191 endotoxin measurements were performed to assess the exposure. RESULTS: Forty percent of workers reported work-related symptoms in the first week of the study. Smoking, endotoxin, and dust concentrations were risk factors for all work-related symptoms. Acute airway responses were witnessed after immediate exposure. Female status was the only factor found to be predictive of acute airway response. The mean longitudinal fall in FEV1 at 1 year was 65.5 mL (standard error = 37.2). Age, early respiratory symptoms, and early fall in cross-week FEV1 were found to predict the 12-month fall in FEV1. Cross-first-shift and cross-week falls in FEV1 reduced in magnitude during the course of the study. CONCLUSIONS: This study of workers naive to cotton dust exposure has demonstrated that respiratory symptoms and acute airway responses develop early following first exposure, and a tolerance effect develops in those workers with the continued exposure. Current smoking and increasing exposure predicts the development of work-related lower respiratory tract symptoms, while early symptoms and acute airway changes across the working week predict the longitudinal loss of lung function at 1 year.

IPEADAM study: indoor endotoxin exposure, family status, and some housing characteristics in English children.

BACKGROUND: Many environmental factors have been investigated to determine their involvement in the asthma epidemic. OBJECTIVE: We sought to investigate the indoor environment of English children. METHOD: The Indoor Pollutants, Endotoxin, Allergens, Damp and Asthma in Manchester (IPEADAM) study recruited 200 asthmatic and age-, sex-, and sibship size-matched nonasthmatic children after a questionnaire-based community screening epidemiology survey. Their homes were sampled for several indoor air factors, and reservoir dust samples were obtained. Endotoxin, Der p 1, and dampness levels were assayed. Questionnaires were administered to record housing characteristics. Indoor pollutants, including environmental tobacco smoke, volatile organic compounds, nitrogen dioxide, formaldehyde, temperature, and relative humidity, were investigated. STATA univariate and multivariate analyses were used to compare the indoor environments of the children. RESULTS: The levels of endotoxin (adjusted odds ratio, 1.88; 95% CI, 1.11-3.18; P=.018), living in a single-parent family (adjusted odds ratio, 3.89; 95% CI, 1.25-12.1; P=.019), redecoration in the living room (adjusted odds ratio, 3.15; 95% CI, 1.36-7.33; P=.008), and self-reported absence of dampness (adjusted odds ratio, 0.36; 95% CI, 0.14-0.91; P=.030) were all independent predictive factors of asthma. There was no difference between asthmatic and healthy children in their exposure to Der p 1, objective measurements of dampness, guardian's smoking habits, pet ownership, house type or age, time in residence, central heating systems, insulation types, glazing systems, floor types, and age and measurements of several indoor pollutants. CONCLUSION: The IPEADAM study has shown that there were very few differences in the indoor environments of English asthmatic and nonasthmatic children. However, once asthma has been established, the presence of endotoxin is positively associated with an asthmatic child's living room carpet reservoir dust. CLINICAL IMPLICATIONS: There are no direct clinical implications of this research, although it needs interpreting with other clinical data on endotoxin exposure in epidemiologic settings.
