Parental child-rearing attitudes are associated with functional constipation in childhood.

OBJECTIVE: Parenting factors are assumed to play a role in the development and maintenance of childhood constipation. However, knowledge about the association between parenting factors and childhood constipation is limited. This study investigates the association between parental child-rearing attitudes and prominent symptoms of functional constipation and assesses the strength of this association. DESIGN: Cross-sectional data of 133 constipated children and their parents were collected. SETTING: The gastrointestinal outpatient clinic at the Emma Children's Hospital in the Netherlands. PATIENTS: Children with functional constipation aged 4-18 years referred by general practitioners, school doctors and paediatricians. MAIN OUTCOME MEASURES: Parental child-rearing attitudes were assessed by the Amsterdam version of the Parental Attitude Research Instrument (A-PARI). Symptoms of constipation in the child were assessed by a standardised interview. Negative binomial and logistic regression models were used to test the association between child-rearing attitudes and constipation symptoms. RESULTS: Parental child-rearing attitudes are associated with defecation and faecal incontinence frequency. Higher and lower scores on the autonomy attitude scale were associated with decreased defecation frequency and increased faecal incontinence. High scores on the overprotection and self-pity attitude scales were associated with increased faecal incontinence. More and stronger associations were found for children aged ≥6 years than for younger children. CONCLUSIONS: Parental child-rearing attitudes are associated with functional constipation in children. Any parenting issues should be addressed during treatment of children with constipation. Referral to mental health services is needed when parenting difficulties hinder treatment or when the parent-child relationship is at risk. TRIAL REGISTRATION NUMBER: ISRCTN2518556.

Parental perceptions of child vulnerability in a community-based sample: Association with chronic illness and health-related quality of life.

The study aimed to assess the prevalence of parental perceptions of a child's vulnerability (PPCV) in a Dutch community-based sample and its relationship with children's health and health-related quality of life (HRQoL). Parents completed the Child Vulnerability Scale and a socio-demographic questionnaire. The Pediatric Quality of Life Inventory 4.0 was administered to measure HRQoL. The prevalence of PPCV was assessed in relation to socio-demographic and health-related characteristics. In a three-step multiple hierarchical regression model, the mediational role of PPCV in the association between chronic illness and HRQoL was investigated. Participants were 520 Dutch children aged 5-18 years from nine Dutch schools. In all, 69 (13.3%) had a chronic illness; 1.9% was perceived vulnerable, 3.0% in groups 5-7 and 1.7% in groups 8-12 and 13-18. Younger age of the child, presence of a chronic illness and low HRQoL were associated with PPCV. PPCV partially mediated the negative association between chronic illness and HRQoL. In conclusion, PPCV is associated with adjustment to chronic illness. More research is needed regarding the mechanisms through which PPCV affects HRQoL and to examine whether PPCV can be targeted in parenting interventions.

Feasibility of an online cognitive behavioral-based group intervention for adolescents treated for cancer: a pilot study.

The objective of this study was to investigate satisfaction with and feasibility of an online cognitive behavioral-based group intervention (OK Onco Online) for adolescent childhood cancer survivors (CCS). The intervention, carried out by pediatric psychologists, aimed to prevent psychosocial problems. High levels of satisfaction were reported by the psychologists (n=6) and the CCS (n=11, age 11­17). The dropout rate was very low. Some recommendations for optimizing the intervention were mentioned. In conclusion, the positive evaluations by the CCS and the psychologists indicate that the online chat intervention OK Onco Online is a promising innovative group intervention for adolescent CCS. Further research is needed to confirm feasibility and to establish efficacy.

Childhood brain tumor survivors at risk for impaired health-related quality of life.

This study aimed to assess health-related quality of life (HRQOL)-mean scores and percentages at risk for impaired HRQOL in childhood brain tumor survivors (CBTS) and to explore differences between CBTS treated with surgery only (SO) versus CBTS treated with surgery and adjuvant therapy (SA). HRQOL was evaluated in 34 CBTS (mean age=14.7 y; mean time since the end of treatment=6.4 y) with the KIDSCREEN. Being at risk for impaired HRQOL was defined as a T-score ≥1 SD below the norm population mean. The total and the SA group, but not the SO group, had significantly lower mean scores than the Dutch norm population in the domains of "physical well-being," "psychological well-being," and "peers and social support." High percentages (35% to 53%) of both the SO and the SA groups appeared to be at risk for impaired HRQOL in the domains of "physical well-being," "moods and emotions," "peers and social support," and "bullying," compared to 16% in the norm population. In conclusion, although HRQOL in some domains appeared similar to the norm population, a considerable number of CBTS-reported impaired HRQOL in several other domains. It is recommended to systematically monitor HRQOL in CBTS regardless of the therapy applied.

Efficacy of psychosocial group intervention for children with chronic illness and their parents.

OBJECTIVE: To investigate the efficacy of a cognitive-behavioral group intervention for children with chronic illnesses and to test the effect of an added parent component. METHODS: Children (n = 194) and their parents participated in a multicenter randomized clinical trial comparing a child-only intervention and a parent-child intervention to a wait-list control group. Primary outcomes were parent- and self-reported internalizing and externalizing problems; secondary outcomes were child disease-related coping skills (information seeking, relaxation, social competence, medical compliance, and positive thinking). Assessments took place at baseline and at 6- and 12-month follow-ups. Intention-to-treat mixed-model analyses were performed to test the difference in change in outcomes. RESULTS: The intervention had a positive effect on changes in parent-reported internalizing problems, child-reported externalizing problems, information seeking, social competence, and positive thinking. The additional effect of parental involvement was observed on parent-reported internalizing problems, child-reported externalizing problems, information seeking, and social competence. Illness severity and illness type did not moderate the effects. There were no intervention effects on child-reported internalizing problems, parent-reported externalizing problems, relaxation, or medical compliance. Of the families in the wait-list control group, 74% sought alternative psychological support during the intervention period. CONCLUSIONS: This RCT supports the efficacy of a protocol-based group intervention for children with chronic illnesses and their parents. Adding a parental component to the intervention contributed to the persistence of the effects. Future research should focus on moderating and mediating effects of the intervention.

Perinatal risk factors for neurocognitive impairments in preschool children born very preterm.

AIM: This study aimed to compare a broad array of neurocognitive functions (processing speed, aspects of attention, executive functioning, visual-motor coordination, and both face and emotion recognition) in very preterm and term-born children and to identify perinatal risk factors for neurocognitive dysfunctions. METHOD: Children who were born very preterm (n=102; 46 males, 56 females), defined as a gestational age of less than 30 weeks and/or birthweight under 1000 g, and a comparison group of term-born children (n=95; 40 males, 55 females) were assessed at age 5 with the Wechsler Preschool and Primary Scale of Intelligence, Stop Signal Task, several tasks of the Amsterdam Neuropsychological Tasks, and a Digit Span task. RESULTS: When sociodemographic characteristics were taken into account, very preterm children scored worse than term-born children on all neurocognitive functions, except on tasks measuring inhibition and sustained attention, for which results were inconclusive. Effect sizes for group effects were small to medium (r(2) varying between 0.02 and 0.07). Principal component isolated four factors: visual-motor coordination, face/emotion recognition, reaction time/attention, and accuracy/attention. When sociodemographic and child characteristics at birth were accounted for, bronchopulmonary dysplasia was significantly negatively associated with all four components and also with working memory. INTERPRETATION: Very preterm children are at risk for problems on a broad array of neurocognitive functions. Bronchopulmonary dysplasia is an independent risk factor for impaired neurocognitive functioning.

Health- related quality of life and self-worth in 10-year old children with congenital hypothyroidism diagnosed by neonatal screening.

BACKGROUND: Much is written about cognitive and motor development; less is known about social and emotional consequences of growing up with congenital hypothyroidism (CH).The objectives of the study were: (1) to compare health related quality of life (HRQoL) and self-worth of 10 year old patients with CH with the general population; (2) to explore associations of disease factors, IQ and motor skills with the outcomes. METHODS: Children with CH and their parents completed several questionnaires. Patients were classified to 'severe CH, n = 41' or 'moderate/mild CH, n = 41' based on pre-treatment FT4 concentration.Differences between CH and the general population were tested by analysis of covariance and one sample t-tests (mean scale scores HRQoL and self-worth), chi-square tests and binomial tests (% at risk of impaired HRQoL and self-worth). Linear regression analyses corrected for gender were conducted to explore associations of the outcomes with disease factors, IQ and motor skills. RESULTS: Patients with CH reported lower mean HRQoL on motor, cognitive and social functioning, and on autonomy and positive emotions (p < 0.0001). Patients were also more often at risk for impaired HRQoL and self-worth. No differences were found between the severity groups. Lower IQ was only significant associated with worse cognitive HRQoL. Initial FT4 plasma, age at onset of therapy, initial T4 dose and motor skills were not significantly associated with HRQoL and self-worth. CONCLUSIONS: Negative consequences in terms of HRQoL and self-worth are prevalent in children with CH, independent of disease factors, IQ and motor skills. Physicians should to be attentive to these consequences and provide attention and supportive care.

Evaluation of cognitive and motor development in toddlers with congenital hypothyroidism diagnosed by neonatal screening.

OBJECTIVE: The Dutch neonatal congenital hypothyroidism (CH) screening procedure and treatment modality has been adapted several times since its national institution in 1981. These changes enabled us to investigate whether earlier treatment has resulted in improved cognitive and motor outcomes. The present study examined whether the advancement of treatment modality has resulted in improved cognitive and motor outcomes. METHODS: In 95 toddlers with thyroidal CH (CH-T), born in 2002 through 2004 and treated at a median age of 9 days, cognitive and motor outcomes were assessed with the Bayley Scales of Infant Development-II-NL at 1 and 2 years of age. This outcome was also analyzed in relation to treatment variables. RESULTS: The mean mental developmental index (MDI) scores of the severe (initial free thyroxine [FT4] ≤0.4 ng/dL (≤5 pmol/L), moderate (0.4 < initial FT4 ≤ 0.8 ng/dL (5.0 < initial FT4 ≤ 10.0 pmol/L), and mild (initial FT4 > 0.8 ng/dL (>10.0 pmol/l) CH-T groups at 1 year and the moderate and mild CH-T groups at 2 years were similar to the population mean. The mean MDI scores of the total CH-T group and severe CH-T group at 2 years were significantly lower than the population mean (p < .0001). In all 3 severity subgroups, significant lower psychomotor developmental index scores (p < .0001) were observed. No correlations were found between starting day of treatment and developmental outcome. Initial T4 concentration and initial T4 dose were weak predictors for developmental outcome. CONCLUSION: Essentially, comparable with our earlier findings, children with CH, especially those with severe CH, are still at risk for motor and cognitive problems, which are probably due to the consequence of the prenatal hypothyroid state or the thyroid hormone deficiency in early life.

Difference in mother-child interaction between preterm- and term-born preschoolers with and without disabilities.

AIM: To investigate differences in the quality of mother-child interaction between preterm- and term-born children at age 5, and to study the association of mother-child interaction with sociodemographic characteristics and child disability. METHODS: Preterm children (n = 94), born at <30 weeks' gestation and/or birth weight <1000 g, and term children (n = 84) were assessed at corrected age of 5 using a mother-child interaction observation. Disabilities were assessed using an intelligence test, behaviour questionnaires for parents and teachers, and motor and neurological examinations. RESULTS: Mothers of preterm-born children were less supportive of and more interfering with their children's autonomy than mothers of term-born children. This difference was only partly explained by sociodemographic factors. Dyads showed a lower quality of mother-child interaction if children had a severe disability, especially when mothers had a lower level of education. CONCLUSION: Five years after birth, mother-child interaction of very premature children and their mothers compared unfavourably with term children and their mothers. Mothers with sociodemographic disadvantages, raising a preterm child with severe disabilities, struggle most with giving adequate sensitive support for the autonomy development of their child. Focused specialized support for these at risk groups is warranted.

Prediction of cognitive abilities at the age of 5 years using developmental follow-up assessments at the age of 2 and 3 years in very preterm children.

AIM: This study investigated prediction of separate cognitive abilities at the age of 5 years by cognitive development at the ages of both 2 and 3 years, and the agreement between these measurements, in very preterm children. METHODS: Preterm children (n=102; 44 males; 58 females) with a gestational age less than 30 weeks and/or birthweight less than 1000g were assessed at the ages of 2 and 3 years using the second edition of the Bayley Scales of Infant Development, the Child Behaviour Checklist, and a neurological examination, and at the age of 5 years using the third edition of the Wechsler Preschool and Primary Scale of Intelligence. RESULTS: Cognitive development at ages 2 and 3 years explained 44% and 57% respectively of full-scale intelligence at the age of 5 years. Adding psychomotor, neurological, and behavioural outcomes to the regression model could not or only marginally improve the prediction; adding perinatal and sociodemographic characteristics to the regression model increased the explained variance to 57% and 64% respectively. These percentages were comparable for verbal intelligence. Processing speed quotient and especially performance intelligence were predicted less accurately. INTERPRETATION: Not all aspects of intelligence are predicted sufficiently by the Mental Development Index at ages 2 and 3 years. Follow-up of very preterm children until at least the age of 5 years is needed to distinguish between different aspects of cognitive development.

A cognitive behavioral based group intervention for children with a chronic illness and their parents: a multicentre randomized controlled trial.

BACKGROUND: Coping with a chronic illness (CI) challenges children's psychosocial functioning and wellbeing. Cognitive-behavioral intervention programs that focus on teaching the active use of coping strategies may prevent children with CI from developing psychosocial problems. Involvement of parents in the intervention program may enhance the use of learned coping strategies in daily life, especially on the long-term. The primary aim of the present study is to examine the effectiveness of a cognitive behavioral based group intervention (called 'Op Koers') 1 for children with CI and of a parallel intervention for their parents. A secondary objective is to investigate why and for whom this intervention works, in order to understand the underlying mechanisms of the intervention effect. METHODS/DESIGN: This study is a multicentre randomized controlled trial. Participants are children (8 to 18 years of age) with a chronic illness, and their parents, recruited from seven participating hospitals in the Netherlands. Participants are randomly allocated to two intervention groups (the child intervention group and the child intervention combined with a parent program) and a wait-list control group. Primary outcomes are child psychosocial functioning, wellbeing and child disease related coping skills. Secondary outcomes are child quality of life, child general coping skills, child self-perception, parental stress, quality of parent-child interaction, and parental perceived vulnerability. Outcomes are evaluated at baseline, after 6 weeks of treatment, and at a 6 and 12-month follow-up period. The analyses will be performed on the basis of an intention-to-treat population. DISCUSSION: This study evaluates the effectiveness of a group intervention improving psychosocial functioning in children with CI and their parents. If proven effective, the intervention will be implemented in clinical practice. Strengths and limitations of the study design are discussed. TRIAL REGISTRATION: Current Controlled Trials ISRCTN60919570.

High incidence of multi-domain disabilities in very preterm children at five years of age.

OBJECTIVES: To describe the prevalence and co-occurrence of disabilities and their association with parental education in preterm children and term control subjects. STUDY DESIGN: In a prospective study, preterm children (n=104), born at <30 weeks' gestation or birth weight <1000 g, and term children (n=95) were assessed at corrected age 5 with an intelligence quotient (IQ) test, behavior questionnaires for parents and teachers, and motor and neurologic tests. A disability was defined as results in the mild abnormal range of each test or below. Associations of outcomes with parental education were studied. RESULTS: Of the preterm children, 75% had at least one disability and 50% more than one, compared with 27% and 8%, respectively, of term control subjects (P<.01). The preterm-term difference in full scale IQ increased from 5 IQ points if parental education was high to 14 IQ points if it was low, favoring the term children in both groups. A similar pattern was found for behavior, but not for motor and neurologic outcome. CONCLUSIONS: Disabilities occur frequently after very preterm birth and tend to aggregate. Neurologic and motor outcomes are mostly influenced by biologic risk, and social risks contribute to cognitive and behavioral outcome.

Explorative study on the aftercare of pediatric brain tumor survivors: a parents' perspective.

PURPOSE: Whilst the need for aftercare for long-term sequelae of brain tumor survivors is well known and evident, information from a parent's perspective is lacking on whether the need for aftercare is detected in time, and whether the aftercare is timely initiated and meets the needs for aftercare. METHODS: A survey regarding aftercare in five domains of long-term sequelae (neurocognitive, physical, emotional, social and parenting problems) was sent to 57 parents of survivors treated for a brain tumor in our center. RESULTS: Forty-two (74%) parents participated in this study. With a mean period of 8.1 years (SD = 3.9) since start of treatment, the majority of the survivors (mean age = 14.7 years, SD = 3.8) needed aftercare in several domains of functioning. This need was highest and most met for physical sequelae (N = 34), and lowest but still substantial and least met for parental difficulties (N = 11). Parents of survivors with surgery only as treatment reported a similar need for aftercare as those of survivors with adjuvant therapy. Most of the survivors received aftercare; however, substantial delay of aftercare and self-referral for aftercare were frequently reported. Furthermore, parents showed a lack of knowledge about and use of aftercare services. CONCLUSIONS: Increased awareness for the need for psychosocial aftercare is required. Coaching, psycho-educative programs about coping with the long-term sequelae and information about available specialized aftercare services are required to meet the needs of brain tumor survivors and their parents more adequately.

Course and predictors of posttraumatic stress disorder in parents after pediatric intensive care treatment of their child.

OBJECTIVE: To study posttraumatic stress disorder (PTSD) in parents after unexpected pediatric intensive care unit (PICU) treatment of their child and to identify risk factors for its development. METHOD: Parents completed PTSD questionnaires 3 and 9 months (N = 190) after PICU treatment. Risk factors included pretrauma data, medical data, social demographics and posttraumatic stress responses at 3 months. RESULTS: In total, 30.3% of parents met criteria for subclinical PTSD and 12.6% for clinical PTSD at 3 months. Clinical PTSD prevalence rates did not change over time. At 9 months, 10.5% of parents still met criteria for PTSD. Number of earlier stressful life events, earlier psychosocial care and posttraumatic stress responses at 3 months predicted persistent subclinical and clinical PTSD. CONCLUSIONS: PICU admission is a stressful event associated with persistent parental PTSD. Assessment of risk factors can facilitate detection of persistent PTSD for early intervention.

Prevalence and associated clinical characteristics of behavior problems in constipated children.

OBJECTIVE: Behavior problems are common in children with functional constipation. This study assessed the prevalence of overall, internalizing, and externalizing behavior problems in children with functional constipation and explored which clinical characteristics of constipation are associated with these behavior problems. METHODS: Children who had functional constipation, were aged 4 to 18 years, and were referred to the gastrointestinal outpatient clinic at the Emma Children's Hospital were eligible for enrollment. This study made use of baseline data of 133 children who participated in a randomized, controlled trial that evaluated the clinical effectiveness of behavioral therapy compared with conventional treatment. Prevalence of behavior problems was assessed by the Child Behavior Checklist. Univariate and multivariate logistic regression models were used to test the association between clinical characteristics and behavior problems. RESULTS: The prevalence rate of overall, internalizing, and externalizing behavior problems was considerable: respectively 36.8%, 36.1%, and 27.1% compared with 9% in the Dutch norm population. A long duration of treatment was found to have the strongest association with overall and externalizing behavior problems in children with constipation. Children with constipation and nighttime urinary incontinence have an increased risk for having overall behavior problems. Fecal incontinence and the production of large stools seemed to be exclusively related to externalizing behavior problems. CONCLUSIONS: Behavior problems are common in children who have constipation and are referred to gastrointestinal outpatient clinics, suggesting that a behavioral screening should be incorporated into the diagnostic workup of children with constipation.

A pilot study on peritraumatic dissociation and coping styles as risk factors for posttraumatic stress, anxiety and depression in parents after their child's unexpected admission to a Pediatric Intensive Care Unit.

AIM: To study the prevalence of posttraumatic stress disorder (PTSD), anxiety and depression in parents three months after pediatric intensive care treatment of their child and examine if peritraumatic dissocation and coping styles are related to these mental health problems. METHODS: This is a prospective cohort study and included parents of children unexpectedly admitted to the Pediatric Intensive Care Unit (PICU) from January 2006 to March 2007. At three months follow-up parents completed PTSD (n = 115), anxiety and depression (n = 128) questionnaires. Immediately after discharge, parents completed peritraumatic dissocation and coping questionnaires. Linear regression models with generalized estimating equations examined risk factors for mental health problems. RESULTS: Over 10% of the parents were likely to meet criteria for PTSD and almost one quarter for subclinical PTSD. Respectively 15% to 23% of the parents reported clinically significant levels of depression and anxiety. Peritraumatic dissocation was most strongly associated with PTSD, anxiety as well as depression. Avoidance coping was primarily associated with PTSD. CONCLUSION: A significant number of parents have mental health problems three months after unexpected PICU treatment of their child. Improving detection and raise awareness of mental health problems is important to minimize the negative effect of these problems on parents' well-being.

Behavioral and emotional problems in children with sickle cell disease and healthy siblings: Multiple informants, multiple measures.

BACKGROUND: Behavioral and emotional problems in children with sickle cell disease (SCD) may be related to disease factors, or to socio-demographic factors. The aim of this study was to investigate the prevalence of behavioral and emotional problems in children with SCD living in a Western European country, compared to healthy siblings (who were comparable in age, gender, ethnicity, and socio-economic status-SES), and to a Dutch norm population. METHODS: The Child Behavior Checklist (CBCL), Teacher Report Form (TRF) and Disruptive Behavior Disorders rating scale (DBD) were distributed among caregivers and teachers of 119 children with SCD aged 6-18 years and among caregivers and teachers of 38 healthy siblings. RESULTS: Questionnaires were returned by caregivers and/or teachers of 106 children with SCD and 37 healthy siblings. According to caregivers and teachers, children with SCD had more severe internalizing problems than healthy siblings and the norm population. According to teachers, subgroups of both children with SCD and healthy siblings had more severe externalizing problems than the norm population. Children with SCD had more difficulties than healthy siblings in terms of school functioning, showed less competent social behavior and tended to have more attention deficits. CONCLUSIONS: Children with SCD are at increased risk of developing internalizing problems as a result of their disease. Subgroups of children with SCD are at increased risk of developing severe externalizing problems, which may either be related to socio-demographic factors, or to disease factors, such as neurocognitive deficits associated with cerebral infarction.

Evaluation of a psychoeducational intervention for adolescents with inflammatory bowel disease.

OBJECTIVES: Inflammatory bowel disease (IBD), comprising Crohn's disease, ulcerative colitis, and indeterminate colitis, often has its onset in adolescence. The aim of this study was to evaluate whether a psychoeducational group intervention (aiming to enhance information seeking and giving about the disease, relaxation, social competence, and positive thinking) can strengthen the coping efforts of adolescents with IBD and have a positive effect on their Health-Related Quality of Life (HRQoL). METHODS: Adolescent IBD patients from the Emma Children's Hospital AMC and adolescent members of the Crohn and Ulcerative Colitis Association in The Netherlands, were invited to participate in The intervention study. Using reliable and valid self-report instruments the adolescent's coping styles, feelings of competence, and HRQoL were assessed before and 6-8 months after the intervention. The parents were asked to fill in the Child Behavior Check List. Linear regression analyses were performed to test whether group participation was predictive of the outcome measures while correcting for the first measurement occasion and sex. RESULTS AND CONCLUSION: Forty patients responded positively to invitation to the intervention. Eighteen adolescents, however, lived too far away to attend and served as a control group. Twenty-two children were enrolled and attended in groups of four to six children in six group sessions, supervised by two psychologists. The intervention seemed to have a positive effect on: coping (predictive control, P<0.01), feelings of competence (global self-worth, P<0.05 and physical appearance, P<0.01), and HRQoL (body image, P<0.05). These results give good reason to continue this intervention study with a larger population.

The course of life of patients with childhood atopic dermatitis.

Atopic dermatitis mainly covers the period of infancy to adulthood, an important period in the development of an individual. The impairment of quality of life and the psychological wellbeing of children with atopic dermatitis have been well documented but so far no data exist about the impact of atopic dermatitis in childhood on fulfilling age-specific developmental tasks and achieving developmental milestones during this period, referred to as the course of life. The aims of this study were to: (i) assess the course of life and define the disease-related consequences in young adult patients with childhood atopic dermatitis and (ii) determine whether the severity of atopic dermatitis is predictive for the course of life, the disease-related consequences and quality of life later in life. Adult patients who grew up with atopic dermatitis were asked to complete a medical history questionnaire, the Skindex-29, the "course of life" questionnaire and a subjective disease-specific questionnaire. Patients with severe atopic dermatitis in childhood showed a significant delayed social development in their course of life. The results of the disease-specific questionnaire demonstrated remarkable high percentages of psycho-social consequences and physical discomfort caused by atopic dermatitis in childhood. Patients showed a severely negative impact of atopic dermatitis on their current quality of life. This is the first study that applied the "course of life" questionnaire in atopic dermatitis. More insight in the course of life, disease-specific consequences and quality of life of atopic dermatitis is of high importance, especially in case of severe atopic dermatitis.

White matter fractional anisotropy correlates with speed of processing and motor speed in young childhood cancer survivors.

PURPOSE: To determine whether childhood medulloblastoma and acute lymphoblastic leukemia (ALL) survivors have decreased white matter fractional anisotropy (WMFA) and whether WMFA is related to the speed of processing and motor speed. METHODS AND MATERIALS: For this study, 17 patients (6 medulloblastoma, 5 ALL treated with high-dose methotrexate (MTX) (4 x 5 g/m(2)) and 6 with low-dose MTX (3 x 2 g/m(2))) and 17 age-matched controls participated. On a 3.0-T magnetic resonance imaging (MRI) scanner, diffusion tensor imaging (DTI) was performed, and WMFA values were calculated, including specific regions of interest (ROIs), and correlated with the speed of processing and motor speed. RESULTS: Mean WMFA in the patient group, mean age 14 years (range 8.9 - 16.9), was decreased compared with the control group (p = 0.01), as well as WMFA in the right inferior fronto-occipital fasciliculus (IFO) (p = 0.03) and in the genu of the corpus callosum (gCC) (p = 0.01). Based on neurocognitive results, significant positive correlations were present between processing speed and WMFA in the splenium (sCC) (r = 0.53, p = 0.03) and the body of the corpus callosum (bCC) (r = 0.52, p = 0.03), whereas the right IFO WMFA was related to motor speed (r = 0.49, p < 0.05). CONCLUSIONS: White matter tracts, using a 3.0-T MRI scanner, show impairment in childhood cancer survivors, medulloblastoma survivors, and also those treated with high doses of MTX. In particular, white matter tracts in the sCC, bCC and right IFO are positively correlated with speed of processing and motor speed.
