RESUMO
OBJECTIVE: To prospectively delineate self-reported health-related quality of life (HRQOL) of adolescents and young adults (AYAs) 8 and 10 years after an epilepsy diagnosis and evaluate the degree of AYA-parent agreement in ratings of AYA's HRQOL. METHODS: Data came from the Health-Related Quality of Life in Children with Epilepsy Study (HERQULES), a 10-year longitudinal study of children, aged 4-12 years, with newly diagnosed epilepsy. Epilepsy-specific HRQOL was self-reported by AYA 8 and 10 years after diagnosis and by parents at multiple time points throughout the 10-year follow-up. Measurers of HRQOL over time were analyzed using a linear mixed-effect model approach. AYA-parent agreement was evaluated using intraclass correlation coefficient (ICC) and Bland-Altman plots. RESULTS: A total of 165 AYAs participated at long-term follow-up. There was considerable heterogeneity among AYA's HRQOL, and as a group, there was no significant change in HRQOL from the 8- to 10-year follow-up. Household income at the time of diagnosis, seizure control at follow-up, and a history of emotional problems (anxiety/depression) were independent predictors of HRQOL at follow-up. AYA-parent agreement on AYA's HRQOL was moderate (ICC 0.62, 95% CI 0.51-0.71), although considerable differences were observed at the individual level. AYA-parent agreement varied with AYA's and parent's age, seizure control, and family environment. SIGNIFICANCE: In the long-term after a diagnosis of epilepsy, AYAs report stable HRQOL over time at the group level, although notable individual differences exist. Seizure control, anxiety/depression, and family environment meaningfully impact AYA's long-term HRQOL. AYA and parent reports on HRQOL are similar at the group level, although they cannot be used interchangeably, given the large individual differences observed.

OBJECTIVE: This study estimated trajectories of health-related quality of life (HRQOL) over a 10-year period among children newly diagnosed with epilepsy. We also modeled the characteristics of children, parents, and families associated with each identified trajectory. METHODS: Data came from the HERQULES (Health-Related Quality of Life in Children With Epilepsy Study), a Canada-wide prospective cohort study of children (aged 4-12 years) with newly diagnosed epilepsy. Parents reported on their children's HRQOL at diagnosis, and at 0.5-, 1-, 2-, 8-, and 10-year follow-ups using the Quality of Life in Childhood Epilepsy Questionnaire-55. Trajectories of HRQOL were identified using latent class growth models. Characteristics of children, parents, and families at the time of diagnosis that were associated with each trajectory were identified using multinomial logistic regression. RESULTS: A total of 367 children were included. Four unique HRQOL trajectories were identified; 11% of the cohort was characterized by low and stable scores, 18% by intermediate and stable scores, 35% by intermediate scores that increased then plateaued, and 43% by high scores that increased then plateaued. Absence of comorbidities, less severe epilepsy, and better family environment (greater satisfaction with family relationships and fewer family demands) at the time of diagnosis were associated with better long-term HRQOL trajectories. Although the analyses used estimates for missing values and accounted for any nonrandom attrition, the proportion of children with poorer HRQOL trajectories may be underestimated. SIGNIFICANCE: Children with new onset epilepsy are heterogenous and follow unique HRQOL trajectories over the long term. Overall, HRQOL improves for the majority in the first 2 years after diagnosis, with these improvements sustained over the long term.

OBJECTIVES: The objective of this study was to examine the association between convulsive status epilepticus (CSE) and health-related quality of life (HRQL) during a 24-month follow-up in a multisite incident cohort of children with epilepsy. METHODS: Data were collected in the Health-Related Quality of Life Study in Children with Epilepsy Study from 374 families of children with newly diagnosed epilepsy. The Quality of Life in Childhood Epilepsy (QOLCE) Questionnaire was used to evaluate parent-reported child HRQL. Hierarchical linear regression was used to examine the relationship between CSE and HRQL at 24 months postepilepsy. A total of 359 families completed the 24-month assessment. RESULTS: Twenty-two children (6.1%) had experienced CSE during the follow-up. Children with and without CSE were similar, except a larger proportion of children with CSE had partial seizures (p < 0.001). Controlling for clinical, demographic, and family characteristics, CSE was significantly associated with poorer HRQL (ß = -4.65, p = 0.031). The final model explained 47% of the variance in QOLCE scores. CONCLUSIONS: The findings suggested that not only do children with CSE have significantly poorer HRQL compared with their non-CSE counterparts, but that this factor is independent of the effects of demographic and clinical features known to affect HRQL.

PURPOSE: Little is known about subgroups of children with epilepsy who may experience less favorable outcomes over time. The objectives of this study were to document trajectories of health-related quality of life (HRQL) and to identify predictors of the trajectory group in children with new-onset epilepsy. METHODS: Data were obtained from the Health Related Quality of Life in Children with Epilepsy Study, a prospective multisite study of children 4-12 years old with new-onset epilepsy followed for 24 months. Health-related quality of life was measured using the Quality of Life in Childhood Epilepsy questionnaire. Trajectories of HRQL were investigated using latent class trajectory modeling. Multinomial logistic regression was used to identify child, parent, and family predictors of HRQL trajectories. KEY FINDINGS: A total of 374 families responded at baseline and 283 (76%) completed the study. Five HRQL trajectories were observed: low-increasing (4%), moderate-decreasing (12%), moderate-increasing (22%), high-increasing (32%), and high-stable (30%). Many children in the low-increasing, moderate-increasing, high-increasing, and high-stable had clinically meaningful improvements in HRQL: 82%, 47%, 63%, and 44%, respectively. In contrast, the majority of children in the moderate-decreasing group (56%) experienced clinically meaningful declines in their HRQL. Factors predicting trajectories were number of antiepileptic drugs prescribed, presence of comorbid behavior or cognitive problems, parent depression, and family functioning and demands. SIGNIFICANCE: Results suggested that children with epilepsy are not homogenous but rather consist of groups with different trajectories and unique predictors of HRQL. Problems associated with child behavior and cognition were the strongest predictors identified. Given that several risk factors are modifiable, it is important to examine these as potential targets within a family-centered framework to improve HRQL of children with new-onset epilepsy.

OBJECTIVES: To assess health-related quality of life (HRQL) over 2 years in children 4-12 years old with new-onset epilepsy and risk factors. METHODS: Data are from a multicenter prospective cohort study, the Health-Related Quality of Life Study in Children with Epilepsy Study (HERQULES). Parents reported on children's HRQL and family factors and neurologists on clinical characteristics 4 times. Mean subscale and summary scores were computed for HRQL. Individual growth curve models identified trajectories of change in HRQL scores. Multiple regression identified baseline risk factors for HRQL 2 years later. RESULTS: A total of 374 (82) questionnaires were returned postdiagnosis and 283 (62%) of eligible parents completed all 4. Growth rates for HRQL summary scores were most rapid during the first 6 months and then stabilized. About one-half experienced clinically meaningful improvements in HRQL, one-third maintained their same level, and one-fifth declined. Compared with the general population, at 2 years our sample scored significantly lower on one-third of CHQ subscales and the psychosocial summary. After controlling for baseline HRQL, cognitive problems, poor family functioning, and high family demands were risk factors for poor HRQL 2 years later. CONCLUSIONS: On average, HRQL was relatively good but with highly variable individual trajectories. At least one-half did not experience clinically meaningful improvements or declined over 2 years. Cognitive problems were the strongest risk factor for compromised HRQL 2 years after diagnosis and may be largely responsible for declines in the HRQL of children newly diagnosed with epilepsy.

Cerebral edema is the most common neurologic complication of diabetic ketoacidosis in children. A minority of young patients with intracerebral crises in diabetic ketoacidosis present with cerebrovascular accidents. We report 2 adolescent patients with diabetic ketoacidosis who presented with coma and diffuse white matter hemorrhages in the absence of either cerebral edema or cerebrovascular accidents. These 2 cases illustrate a novel clinical and neuropathologic description of diffuse white matter hemorrhages, possibly related to a cytotoxic process as the underlying mechanism. These case descriptions emphasize that pediatric patients with diabetic ketoacidosis and coma can present with pathology not related to either cerebral edema or cerebrovascular accidents.

The apparent diffusion coefficient changes with time after hypoxic-ischemic brain injury. In this study, we quantitatively examined the relationship between the apparent diffusion coefficient and postnatal age for neonates with hypoxic-ischemic encephalopathy and poor outcome, and determined the postnatal age at which these values cannot be distinguished from those of neonates without hypoxic-ischemic encephalopathy (pseudonormalization time). Diffusion-weighted brain images were obtained from clinical scans of term neonates with hypoxic-ischemic encephalopathy and poor outcome (12 neonates, 23 scans) and from control subjects (30 neonates, 31 scans). The correlation between apparent diffusion coefficient and postnatal age was investigated for several brain regions. Pseudonormalization times were determined (1) from the intersection of the regression lines for the hypoxic-ischemic encephalopathy and control groups, as well as (2) from intrasubject apparent diffusion coefficient changes between two scans within a small subgroup. Pseudonormalization times from the regression ranged from 8.3 +/- 1.9 days to 10.1 +/- 2.1 days. Slightly (approximately 1 day) longer values were obtained from the intrasubject analysis. The results suggest that, although abnormally decreased apparent diffusion coefficient values may be evident from approximately 2 days to almost 1 week of postnatal age, abnormally elevated values may not be apparent until late in the second week of life.

STATEMENT OF THE PROBLEM: There is increasing interest in reducing burden of illness in families with childhood epilepsy. Evidence suggests that burden of illness is more related to parents' perception of seizure control than actual seizure control. This study examined the extent to which parents could describe their children's epilepsy and its impact. The degree of concordance between parents' and physicians' perceptions of epilepsy, and its effect on parents' satisfaction with care was also examined. METHOD: The study involved 37 parents and 1 paediatric neurologist. A questionnaire measured parents' perceptions of seizures and satisfaction with care. A physician questionnaire was piloted for comparison with parent responses. RESULTS: Parents were able to describe and distinguish seizure types, characteristics and impact of epilepsy. Results indicate a low degree of concordance between parents' and physician's perceptions for global, medical and everyday aspects of epilepsy. Preliminary evidence suggests that satisfaction with care may be positively related to degree of concordance. CONCLUSIONS: It is feasible to examine burden of illness from the parents' perspective. More attention should be paid to the parent-physician relationship in order for physicians to appreciate parents' perceptions. Future research is needed to replicate the findings in a larger sample of parents and paediatric neurologists.
