Maternal stress and childhood migraine: a new perspective on management

Association Between Migraine and Gastrointestinal Disease in Pediatric Patients: A Propensity Score Weighting Approach

Purpose

Migraine is a neurological disorder affecting pediatric patients of all age groups, with a prevalence ranging from approximately 5% to 15%. It significantly impacts the quality of life in children and adolescents, potentially hampering their learning abilities, school performance, and daily activities. This study investigated the association between migraine and several prevalent gastrointestinal (GI) diseases in pediatric patients.

Patients and Methods

We analyzed the Health Insurance Review and Assessment Service Pediatric Patient Sample (HIRA-PPS) dataset from South Korea. Propensity scores based on patient characteristics (age, sex, and insurance type) were employed through the inverse probability of treatment weighting (IPTW) in binary logistic regression. We included gastroesophageal disease (GERD), peptic ulcer disease (PUD), gastritis, dyspepsia, irritable bowel syndrome (IBS), and inflammatory bowel disease (IBD) as GI diseases.

Results

A total of 683,347 patients from the HIRA dataset were included in the study. After IPTW adjustment, the prevalence of GI diseases among pediatric patients with migraine remained significantly increased (OR 4.15; 95% CI 4.12-4.18). Migraine patients showed higher prevalence rates for all six individual GI diseases, with GERD (OR 4.11; 95% CI 4.05-4.16) and IBS (OR 3.79; 95% CI 3.74-3.84) showing the highest associations. We also confirmed a progressively increasing association between the presence of diagnosed migraine and GI diseases.

Conclusion

This study highlights a strong association between pediatric migraine and GI diseases, even after adjusting for patient characteristics. The elevated prevalence of various GI diseases in migraine patients suggests the need for comprehensive approaches to their prevention and treatment.

The impact of exposure to tobacco smoking and maternal trauma in fetal life on risk of migraine

Introduction

Prenatal period is the key time in human development. Many prenatal factors are well-known and increase the risk of developing diseases' after birth. Few studies indicated the link between the prenatal period and the prevalence of migraine in childhood and adolescence so far. We decided to broaden current knowledge and investigate whether the prenatal factors influence the prevalence of migraine in adulthood. The objective of this study is to provide evidence of relationship between in utero environment and risk of migraine.

Methods

In total 266 females (136 in the migraine group, 130 in the control group) and 80 males (35 in the migraine group, 45 in the control group), aged 18-65 participated in the study. The quality of prenatal environment was characterized on the basis of mother's and father's education, tobacco smoke exposure, alcohol consumption, and traumatic event during pregnancy, which are considered as prenatal factors and affect on fetal development.

Results

Migraine occurrence in adulthood was significantly associated with maternal tobacco smoking during pregnancy (OR 3.42, 95% CI 1.54-7.61, p = 0.036) and traumatic event during pregnancy (OR 2.27, 95% CI 1.24-4.13, p = 0.020).

Discussion

Our study suggests that the fetal programming effect of tobacco smoking exposure and maternal trauma is not limited to prenatal life and is suggested as having a role in adulthood. Our findings support evidence that migraine adulthood can be partly influenced by early life conditions.

Emotional Experience and Regulation in Juvenile Primary Headaches: A Cross-Sectional Pilot Study

A headache is the most common neurological symptom in children. Its subtypes are migraine (MH) and tension-type headache (TTH). Internalizing rather than externalizing symptoms are more frequent in children with headaches, but little is known about the reasons why. We aim to: (a) examine the interplay between emotional experience, affective regulation, and internalizing symptoms in children suffering from primary headaches and their caregivers; (b) identify potential predictors of children with migraines' internalizing symptoms. Fifty children and adolescents with a diagnosis of primary headaches and their caregivers were compared to a sample of fifty-one healthy peers and caregivers. Self-reports and parent-reports were administered. Results indicate higher negative affect and internalizing symptoms and lower bodily awareness of emotions in the clinical sample (n = 50; Mage = 11.66, SD = 2.25) compared to controls (n = 51; Mage = 11.73, SD = 2.32); mothers of TTH children self-reported lower emotional awareness and higher difficulties in engaging in goal-directed behavior; a higher frequency of headaches was associated with greater emotional regulation difficulties. Internalizing symptoms were predicted by higher self-reported negative affect and parent-reported internalizing symptoms, and lower self-reported ability in the verbal sharing of emotions. These findings suggest the importance of assessing the psychological features linked to children with primary headaches' psychological well-being.

Predicting quality of life outcomes in children with migraine

INTRODUCTION

Several studies have shown that the response of children with migraine to medications is suboptimum and inferior to the response reported in adults, despite the similar pathogenesis and biological mechanisms. The poor response may be related to the significant differences that make assessment and treatment of children with migraine more challenging than in adults.

AREAS COVERED

The purpose of this review is to discuss the whole process of assessment of children with migraine, the necessary skills for eliciting the clinical features, making the correct diagnosis and exploring lifestyle issues, co-morbid conditions (psychological and physical) and social influences on disease presentations. Also, to establish and address peculiarities of migraine in children that would enable clinicians to advise on lifestyle modifications, co-morbid conditions and the correct choice of treatment options including non-pharmacologic therapies and medications.

EXPERT OPINION

The choice of treatment should be based on an assessment of each individual child taking into account, age, gender, pubertal status, body weight, comorbid disorders and family history. Also considering the profile of migraine episodes, frequency, duration, associated symptoms and effects of nausea and vomiting. Using the appropriate medications in appropriate dosage, formulation and route and timing of administration may improve adherence to treatment and outcome.

Pediatric Chronic Migraine Severity and Maternal Stress

Primary headache is an increasing phenomenon in pediatric age, and very often, it causes disabling limitations in children's daily activities, negatively affecting family well-being. There are conflicting data in the literature on the impact of children's migraines on parental experienced stress. This study aimed to evaluate maternal stress in a sample of school-aged children with a migraine without aura (MwoA) and its correlation with migraine intensity and frequency. A total of 474 mothers aged between 31 and 55 participated in the study: 237 were mothers of children with MwoA, and 237 were mothers of typical developing children. All participants were administered the Parent Stress Index-Short Form (PSI-SF) for the assessment of parental stress; the Pediatric Migraine Disability Assessment (PedMIDAS) was administered to children with MwoA to assess the presence of a related disability migraine. The results showed a significantly higher rate of stress in mothers of MwoA children (p < 0.001) in all the domains explored by the PSI-SF and a statistically significant correlation between the maternal stress total score and the intensity and frequency of migraine attacks (p < 0.0001). This study highlights the need for the holistic contribution of the family to be considered in the clinical management of pediatric migraines.

Longitudinal Impact of Parent Factors in Adolescents With Migraine and Tension-Type Headache

OBJECTIVE

To examine longitudinal associations between parent factors (parent headache frequency and disability, protective parenting behaviors, parent catastrophizing) with adolescent headache-related disability and headache frequency over 6 months.

BACKGROUND

Theoretical models propose bidirectional, longitudinal relationships between parent factors and adolescent headache. Few studies have examined this using prospective study designs.

DESIGN AND METHODS

Participants were a cohort of 239 youth ages 11-17 years with recurrent migraine (with and without aura; chronic migraine) or tension-type headache (episodic and chronic) and their parents recruited from a pediatric neurology clinic and the community who completed assessments at baseline and 6-month follow-up.

RESULTS

After controlling for demographic and clinical covariates, we found that every point increase in baseline protective parenting behavior corresponded with a 2.19-point increase in adolescent headache frequency at follow-up (P = .026, 95% CI [0.27, 4.10]). Similarly, every point increase in baseline parent catastrophizing corresponded with a 0.93-point increase in adolescent headache-related disability (P = .029, 95% CI [0.09, 1.77]) and a .13-point increase in adolescent headache frequency (P = .042, 95% CI [0.01, 0.25]) at follow-up. We also found support for the reverse association, where every point increase in baseline adolescent headache-related disability predicted a 0.03-point increase in parent catastrophizing (P = .016, 95% CI [0.01, 0.05]) and a 0.02-point increase in protective parenting behavior (P = .009, 95% CI [0.01, 0.03]) at follow-up. The remaining bidirectional, longitudinal associations tested between parent factors and adolescent headache were not statistically significant.

CONCLUSION

Findings suggest that family-based psychological interventions targeting modifiable adolescent and parent factors may lead to improvements in adolescent headache-related disability and reductions in adolescent headache frequency.

The Relationship Between Parental Care and Pain in Children With Headache: A Narrative Review

PURPOSE

In migraine or primary headache in children, parents play a fundamental role in pain management. For this narrative review, PubMed, Google Scholar, and Psych Info were searched using the terms "parent headache", "mother/father headache", "parental impact headache", "alexithymia parents headache", "catastrophizing parent headache", "family headache", "children parent headache", and "quality of life family headache". Articles were chosen for inclusion based on their relevance in to the topic.

OVERVIEW

Several parental and psychological characteristics can influence in children and adolescent headache, such as parental attitudes as oppressive or overprotective; punitive parenting styles; familial psychological symptoms, especially anxiety and depression; catastrophizing about their child's pain or excessive worry about their child's headache; inability to express emotions; and feelings that may lead to somatization problems.

DISCUSSION

Parents' attitudes and behaviors toward their child's headache have a strong relation with the severity of headache attacks. Mothers seem to have more influence than fathers on children's pain and emotional regulation. We suggest that the presence of caregiver-child transmission of maladaptive coping strategies, arising from difficulties expressing emotion, may lead to incorrect management of headache pain, further facilitating headache chronification.

Parental Stress and Parental Ratings of Behavioral Problems of Enuretic Children

Background: Primary monosymptomatic nocturnal enuresis (PMNE) may have a stressful impact on the everyday life of children and parents, and it may represent a cumulative stress factor increasing feelings of “learned helplessness.”

Methods: The current study investigated parental stress in a group of parents (n = 330) of children affected by PMNE, compared to a group of parents (n = 330) of typical developing children (TDC). In addition, the study evaluated whether parents of PMNE children experience more emotional, social, and behavioral problems in their children, compared to parents of TDC. Finally, the study correlated frequency of enuresis with stress values and Child Behavior Checklist (CBCL) subscales and total stress with CBCL. Both groups were given The Parental Stress Inventory-Short Form (PSI-SF) and the Child Behavior Checklist (CBCL).

Results: Parents of PMNE children showed significantly higher stress level than parents of TDC. Nocturnal enuresis, as a demanding clinical condition difficult to control, represents a relevant stress factor. Mothers appeared as more vulnerable to stress than fathers. Parents of PMNE children reported higher behavioral and emotional problems, compared to reports of parents of TDC. PMNE children appeared to their parents as having lower competency in social activities, school performance, and social relationships than TDC. Moreover, they were rated as more withdrawn, anxious-depressed, more aggressive, inattentive, and with more somatic complaints than healthy children. It was always the mother who rated a significantly higher number of emotional, social, and behavioral problems compared to fathers. Correlational analysis showed that the higher the frequency of enuresis, the greater the parental stress level, the lower the social activities, school performance and relational competencies and the higher the emotional, social and behavioral problems in children, according to the parents' evaluations. The greater the parental stress level, the lower the competencies rated and the higher the behavioral problems detected by parents.

Conclusion: The physicians who deal with PMNE children have taken into account the stressful role and emotional dimensions of this clinical condition, both for children and mothers, in order to improve clinical management. Psychological support is needed for parents, and mothers especially, for a more functional stress management related to the PMNE.

Economic Impact of Headache and Psychiatric Comorbidities on Healthcare Expenditures Among Children in the United States: A Retrospective Cross-Sectional Study

OBJECTIVE

To examine the annual healthcare expenditures associated with childhood headache in the United States, and to evaluate whether psychiatric comorbidities increase the impact of headache on expenditures.

BACKGROUND

Headache is prevalent in childhood and co-occurs with anxiety disorders, depressive disorders, and attention deficit/hyperactivity disorder (ADHD), which may increase cost of illness.

METHODS

We conducted a secondary data analysis using a nationally representative sample of 34,633 children ages 2-17 from the 2012-2015 Medical Expenditure Panel Surveys (MEPS), of which 779 (weighted 2.6%) were identified as having headache based on health service use associated with headache. Using a comprehensive cost-of-illness approach, we assessed the incremental expenditures associated with headache and determined excess expenditures associated with psychiatric comorbidities using standard adjusted 2-part expenditure models.

RESULTS

Annual total healthcare expenditures were estimated to be 24.3% higher, 95% CI [1,55], in our headache group ($3036, 95% CI [2374,3699] vs $2350, 95% CI [2140,2559]). Total national expenditures associated with pediatric headache in the United States were estimated at $1.1 billion annually, 95% CI [.04, 2.2 billion]. Depression and ADHD were associated with higher incremental expenditures for the headache group (depression: $1815, 95% CI[676,2953] vs $1409, 95% CI[697,2112]; ADHD: $4742, 95% CI[1659,7825] vs $2935, 95% CI[1977,3894]); however, interactions between psychiatric comorbidities and headache did not reach statistical significance.

CONCLUSION

Youth with headache exert a considerable economic burden on families, healthcare systems, and society. Due to the limitations in methods used to classify youth with headache in MEPS, our findings may underestimate the true prevalence and cost of pediatric headache in the United States. Further research with larger sample sizes is needed to understand the impact of psychiatric comorbidities on healthcare expenditures in this population.

Parenting Stress and Emotional/Behavioral Problems in Adolescents with Primary Headache

Primary headache is a frequent and disabling disorder, common among children and adolescents, and it is a painful syndrome often accompanied by functional impairment and associated with emotional and behavior problems. The aim of this study was to investigate parenting stress and emotional/behavioral problems in adolescents affected by primary headache compared with healthy adolescents. The study population consisted of 35 adolescents and a control group of 23 healthy subjects. The assessment included the administration of clinical standardized scales such as Parent Stress Index-Short Form, Pediatric Migraine Disability Assessment Score Questionnaire, and Child Behavior Checklist (CBCL). Headache group and control group did not differ in terms of parenting stress (p = 0.29). On the contrary, headache group showed more internalizing problems (p = 0.023), affective problems (p = 0.01), anxious (p = 0.001), and somatic complaints (p < 0.001) compared with control group. In addition, we found a significant correlation between PSI domains and specific CBCL subscales in the headache group. The findings emphasize the need for expanded intervention in the clinical treatment of pediatric headache, a treatment that may also include the family members. Further research is needed.

Visual-spatial training efficacy in children affected by migraine without aura: a multicenter study

Routinely in the clinical practice, children affected by migraine without aura (MwA) tend to exhibit severe and persistent difficulties within cognitive processes such as attention, memory, and visual-motor integration (VMI) skills. The aim of this study was to assess the visual-spatial and visual-motor abilities among a sample of children with MwA and the effects of a specific computerized training. The study population was composed of 84 patients affected by MwA (39 girls and 45 boys; mean age: 8.91±2.46 years), and they were randomly divided into two groups (group A and group B) comparable for age (P=0.581), gender (P=0.826), socioeconomic status (SES), migraine frequency (P=0.415), and intensity (P=0.323). At baseline (T0), the two groups were comparable for movement assessment battery for children (M-ABC) and VMI performances. After 6 months of treatment (T1), group A showed lower scores in the dexterity item of M-ABC test (P<0.001) and higher scores in M-ABC global performance centile (P<0.001) and total (P<0.001), visual (P=0.017), and motor (P<0.001) tasks of VMI test than group B. Moreover, at T1, group A showed higher scores in total (P<0.001) and motor (P<0.001) tasks of VMI test and in M-ABC global performance centile (P<0.001) and lower scores in the dexterity item of M-ABC test (P<0.001) than at T0. Group B showed, at T1, performances comparable to T0 for all evaluations. As reported by recent studies about alteration MwA among children in motor abilities, our study confirmed these difficulties and the efficacy of a specific software training, suggesting a new rehabilitative proposal in childhood.

Prophylactic effects of asiaticoside-based standardized extract of Centella asiatica (L.) Urban leaves on experimental migraine: Involvement of 5HT1A/1B receptors

The present study aimed at evaluation of prophylactic efficacy and possible mechanisms of asiaticoside (AS) based standardized extract of Centella asiatica (L.) Urban leaves (INDCA) in animal models of migraine. The effects of oral and intranasal (i.n.) pretreatment of INDCA (acute and 7-days subacute) were evaluated against nitroglycerine (NTG, 10 mg·kg(-1), i.p.) and bradykinin (BK, 10 μg, intra-arterial) induced hyperalgesia in rats. Tail flick latencies (from 0 to 240 min) post-NTG treatment and the number of vocalizations post-BK treatment were recorded as a measure of hyperalgesia. Separate groups of rats for negative (Normal) and positive (sumatriptan, 42 mg·kg(-1), s.c.) controls were included. The interaction of INDCA with selective 5-HT1A, 5-HT1B, and 5-HT1D receptor antagonists (NAN-190, Isamoltane hemifumarate, and BRL-15572 respectively) against NTG-induced hyperalgesia was also evaluated. Acute and sub-acute pre-treatment of INDCA [10 and 30 mg·kg(-1) (oral) and 100 μg/rat (i.n.) showed significant anti-nociception activity, and reversal of the NTG-induced hyperalgesia and brain 5-HT concentration decline. Oral pre-treatment with INDCA (30 mg·kg(-1), 7 d) showed significant reduction in the number of vocalization. The anti-nociceptive effects of INDCA were blocked by 5-HT1A and 5-HT1B but not 5-HT1D receptor antagonists. In conclusion, INDCA demonstrated promising anti-nociceptive effects in animal models of migraine, probably through 5-HT1A/1B medicated action.

Behavioral Phenotype and Autism Spectrum Disorders in Cornelia de Lange Syndrome

Cornelia de Lange syndrome (CdLS) is a congenital disorder characterized by distinctive facial features, growth retardation, limb abnormalities, intellectual disability, and behavioral problems. Cornelia de Lange syndrome is associated with abnormalities on chromosomes 5, 10 and X. Heterozygous point mutations in three genes (NIPBL, SMC3 and SMC1A), are responsible for approximately 50-60% of CdLS cases. CdLS is characterized by autistic features, notably excessive repetitive behaviors and expressive language deficits. The prevalence of autism spectrum disorder (ASD) symptomatology is comparatively high in CdLS. However, the profile and developmental trajectories of these ASD characteristics are potentially different to those observed in individuals with idiopathic ASD. A significantly higher prevalence of self-injury are evident in CdLS. Self-injury was associated with repetitive and impulsive behavior. This study describes the behavioral phenotype of four children with Cornelia de Lange syndrome and ASDs and rehabilitative intervention that must be implemented.

Pharmacoinformatics elucidation of potential drug targets against migraine to target ion channel protein KCNK18

Migraine, a complex debilitating neurological disorder is strongly associated with potassium channel subfamily K member 18 (KCNK18). Research has emphasized that high levels of KCNK18 may be responsible for improper functioning of neurotransmitters, resulting in neurological disorders like migraine. In the present study, a hybrid approach of molecular docking and virtual screening were followed by pharmacophore identification and structure modeling. Screening was performed using a two-dimensional similarity search against recommended migraine drugs, keeping in view the physicochemical properties of drugs. LigandScout tool was used for exploring pharmacophore properties and designing novel molecules. Here, we report the screening of four novel compounds that have showed maximum binding affinity against KCNK18, obtained through the ZINC database, and Drug and Drug-Like libraries. Docking studies revealed that Asp-46, Ile-324, Ile-44, Gly-118, Leu-338, Val-113, and Phe-41 are critical residues for receptor–ligand interaction. A virtual screening approach coupled with docking energies and druglikeness rules illustrated that ergotamine and PB-414901692 are potential inhibitor compounds for targeting KCNK18. We propose that selected compounds may be more potent than the previously listed drug analogs based on the binding energy values. Further analysis of these inhibitors through site-directed mutagenesis could be helpful for exploring the details of ligand-binding pockets. Overall, the findings of this study may be helpful for designing novel therapeutic targets to cure migraine.

Orthodontic treatment need for adolescents in the Campania region: the malocclusion impact on self-concept

BACKGROUND

Dental malocclusions can be considered not only as an oral health problem, because they are linked to quality of life perception. Many factors related to malocclusion have strong influences on the perception of facial esthetics (eg, anterior tooth alignment, tooth shape and position, lip thickness, symmetric gingival or tooth contour, lip profile, and overjet). Many reports have shown that the perception of facial esthetics can influence psychological development from early childhood to adulthood. The aim of this study is to investigate the effect of dental malocclusion on self-esteem in a sample of adolescents.

MATERIALS AND METHODS

The study population was composed of 516 orthodontically untreated subjects (256 males) mean ages 13.75±1.977 years recruited from schools in the Campania region of Italy between January 2011 and July 2011. To evaluate the self-esteem grade in our population, all subjects filled out the Multidimensional Self Concept Scale questionnaire and attended an orthodontic clinical evaluation to estimate dental occlusal aspects.

RESULTS

Pearson's analysis shows the relationship in our sample between some occlusal characteristics (crossbite and dental crowding) and aspects of self-concept evaluation (social, competence, academic, physical, and global score) of the Multidimensional Self Concept Scale questionnaire. Moreover, logistic regression analysis shows the potential role of dental crowding (odds ratio 5.359; 95% confidence interval 3.492-8.225) and crossbite (odds ratio 6.153; 95% confidence interval 3.545-10.678) as risk factors for development of global self-concept score abnormalities.

CONCLUSION

Our findings confirm the relationship between psychosocial well-being, self-esteem, and dental malocclusion among adolescents.

Pediatric neurofibromatosis 1 and parental stress: a multicenter study

BACKGROUND

Neurofibromatosis 1 (NF1) is a complex and multifaceted neurocutaneous syndrome with many and varied comorbidities. The literature about the prevalence and degree of maternal stress and the impact of NF1 in the parent-child interaction is still scant. The aim of this study was to evaluate the prevalence of maternal stress in a large pediatric sample of individuals affected by NF1.

METHODS

Thirty-seven children (19 boys, 18 girls) of mean age 7.86±2.94 (range 5-11) years affected by typical NF1 and a control group comprising 405 typically developing children (207 boys, 198 girls; mean age 8.54±2.47 years) were included in this study. To assess parental stress, the mothers of all individuals (NF1 and comparisons) filled out the Parenting Stress Index-Short Form test.

RESULTS

The two study groups were comparable for age (P=0.116), gender (P=0.886), and body mass index adjusted for age (P=0.305). Mothers of children affected by NF1 reported higher mean Parenting Stress Index-Short Form scores on the Parental Distress domain (P<0.001), Difficult Child domain (P<0.001), and Total Stress domain than the mothers of typically developing children (controls) (P<0.001). No significant differences between the two groups were found for the Parent-Child Dysfunctional Interaction domain (P=0.566) or Defensive Responding domain scores (P=0.160).

CONCLUSION

NF1 is considered a multisystemic and complex disease, with many still unrecognized features in pediatric patients and in their families. In this light, our findings about the higher levels of maternal stress highlight the importance of considering the environmental aspects of NF1 management in developmental age.

Anxiety and depression levels in prepubertal obese children: a case-control study

INTRODUCTION

Childhood obesity has become a worldwide epidemic in Western and in developing countries and has been accompanied by many serious and severe comorbidities, such as diabetes, hypertension, sleep apnea syndrome, depression, dyslipidemia, impaired glucose homeostasis, steatohepatitis, and intracranial hypertension, as well as medical concerns unique to youth, such as accelerated pubertal and skeletal development and orthopedic disorders. To date, no specific studies about the psychological assessment in pediatric obesity are present. Therefore, the aim of this study was to evaluate the putative relationship between psychological troubles and obesity in a sample of school-aged children.

MATERIALS AND METHODS

The study population consists of 148 obese subjects (body mass index [BMI] >95th percentile) (69 males, mean age 8.9±1.23 years) consecutively referred from clinical pediatricians to the Child and Adolescent Neuropsychiatry department at the Second University of Naples. In all subjects, weight, height, and BMI z-score were evaluated. In order to assess the anxiety levels and the presence of depressive symptoms, the Children Depression Inventory (CDI) and the Italian Self-Administered Psychiatric Scales for Children and Adolescents (SAFA) were administered. The control group consisted of 273 healthy children (129 males and 144 females) (mean age 9.1±1.8 years), enrolled in schools within the Campania region of Italy.

RESULTS

No significant differences between the two study groups were found for age (8.9±1.23 years in the obese sample and 9.1±1.8 years in the control group) (P=0.228) or sex (ratio male/female: 69/79 in the obese group versus 129/144 in the control group) (P=0.983). Obviously, significant difference was found for the BMI z-score (2.46±0.31 in the obese group vs 0.73±0.51 in the control group) (P<0.001). The obese subjects showed significant higher level of depressive symptoms (CDI total score) (16.82±7.73 vs 8.2±2.9) (P<0.001) and anxiety (SAFA - Anxiety [SAFA-A]) scale score (58.71±11.84 vs 27.75±11.5) (P<0.001) compared with the control group. Moreover, the Pearson's correlation analysis showed a significantly positive relationship between the BMI z-score and both the CDI (r=0.677; P<0.001) and SAFA-A scores (r=0.591; P<0.001).

CONCLUSION

Our findings highlighted the importance of assessing the presence of internalizing problems, such as anxiety and depression, in the common management of childhood obesity.

Psychological, cognitive and maternal stress assessment in children with primary ciliary dyskinesia

BACKGROUND

Primary ciliary dyskinesia (PCD) is a rare disorder due to structure and functional abnormalities of respiratory cilia. There are no reports on the behavioral and psychological aspects of children and adolescents with PCD. This study was undertaken to assess the cognitive and behavioural characteristics, and the parental stress of a population of school-aged children with PCD.

METHODS

Ten PCD and 34 healthy school-aged children underwent Wechsler Intelligence Scale for Children-III edition, Child Behavior Check-List questionnaire (CBCL), Parenting Stress Index-Short Form tests in order to perform a behavioural and psychological evaluation.

RESULTS

PCD children showed significant behavioral and social competent problems in CBCL scale than control children, in particular with regard to internalizing problems score (P<0.001). Parental distress, parent-child interaction and total stress in the mothers of PCD patients were higher than those in the controls' parents (P<0.001).

CONCLUSION

Our findings pinpoint the importance of specific psychological support in the clinical management of children with PCD.

Migraine and periodic limb movement disorders in sleep in children: a preliminary case-control study

BACKGROUND

The relationships between sleep and headaches are complex and manifold. About the variety of phenomena that can disrupt the sleep macrostructure and can impact its restorative function, the periodic limb movements disorder (PLMd) can be considered as the most powerful.No studies are known about the role of PLMd in the pathophysiology of migraine in children.Aim of study is to assess the prevalence of PLMd and migraine and their relationship with disability and pain intensity in a pediatric sample, referred for migraine without aura by pediatricians.

METHODS

After a preliminary sleep habits screening with the Sleep Disturbances Scale for Children, 34 migraine subjects affected by migraine without aura (20 M, 14 F) (mean age 9.08; SD ± 2.28) and 51 volunteers healthy children (28 M, 23 F) (mean age 9.37; SD ± 1.81) accepted to underwent overnight PSG recordings in the Sleep Laboratory of the Clinic of Child and Adolescent Neuropsychiatry, in order to define the macrostructural sleep characteristics and the prevalence of PLMd. Subsequently, the migraineurs sample was studied in order to define the relationship between disability, pain intensity, therapeutical responsiveness and the presence of PLMd.

RESULTS

In the migraineurs children group, the individuals with PLM pathological index (PLMI ≥ 5) represent the 26.47% of sample and present higher frequency (p < 0.001), intensity (p < 0.001), duration (p = 0.006) and life impairment as scored in the PedMIDAS (p < 0.001) of headache and lower efficacy of prophylactic (p = 0.001) and acute (p = 0.006) pharmacological treatment than MoA children without PLM pathological index.

CONCLUSIONS

This preliminary study indicates the potential value of the determination of the PLMd signs, and the importance of the PSG evaluation in children affected by migraine, particularly when the clinical and pharmacological management tend to fail in the attacks control.

Visuomotor competencies and primary monosymptomatic nocturnal enuresis in prepubertal aged children

BACKGROUND

Primary monosymptomatic nocturnal enuresis (PMNE) is a common problem in the developmental ages; it is the involuntary loss of urine during the night in children older than 5 years of age. Several clinical observations have suggested an association between bedwetting and developmental delays in motricity, language development, learning disability, physical growth, and skeletal maturation. The aim of the present study is to evaluate the prevalence of fine motor coordination and visuomotor integration abnormalities in prepubertal children with PMNE.

METHODS

The study population included 31 children (16 males, 15 females; mean age 8.14 years ± 1.36 years), and the control group comprised 61 typical developing children (32 males, 29 females; mean age 8.03 years ± 1.44 years). The whole population underwent a clinical evaluation to assess total intelligence quotient level, visuomotor integration (VMI) skills, and motor coordination performance (using the Movement Assessment Battery for Children, or M-ABC).

RESULTS

No significant differences between the two study groups were found for age (P = 0.725), gender (P = 0.886), z-body mass index (P = 0.149), or intellectual abilities (total intelligence quotient) (P = 0.163). The PMNE group showed a higher prevalence of borderline performance on M-ABC evaluation and in pathologic performance on VMI Total Task compared to controls (P < 0.001). No significant differences between the two study groups were found for pathologic performances on the M-ABC (P = 0.07), VMI Visual Task (P = 0.793), and VMI Motor Task (P = 0.213).

CONCLUSION

Our findings pinpointed that PMNE should not be considered as a voiding disorder alone and, consequently, the children affected should be referred to specific rehabilitative programs that aim to improve motor coordination and visuomotor integration.

Primary nocturnal enuresis as a risk factor for sleep disorders: an observational questionnaire-based multicenter study

INTRODUCTION

Primary nocturnal enuresis (PNE) is a common problem in developmental age with an estimated overall prevalence ranging from 1.6% to 15%, and possible persistence during adolescence. There is a growing interest in the sleep habits of children affected by PNE, which is derived from the contradictory data present in clinical literature. The aim of the present study was to evaluate the presence of sleep disturbances in a population of children affected by PNE, and to identify whether PNE could be considered as a risk factor for sleep disturbances among children.

MATERIALS AND METHODS

A total of 190 PNE children (97 males, 93 females) aged 7-15 years, (mean 9.64 ± 1.35 years), and 766 typically developing children matched for age (P = 0.131) and gender (P = 0.963) were enrolled. To evaluate the presence of sleep habits and disturbances, all of the subjects' mothers filled out the Sleep Disturbances Scale for Children (SDSC), a questionnaire consisting of six subscales: Disorders in Initiating and Maintaining Sleep (DIMS), Sleep Breathing Disorders (SBD), Disorders of Arousal (DA), Sleep-Wake Transition Disorders (SWTD), Disorders of Excessive Somnolence (DOES), and Nocturnal Hyperhidrosis (SHY). The results were divided into "pathological" and "normal" scores using a cut-off value (pathological score = at least three episodes per week), according to the validation criteria of the test. Then, the Chi-square test was used to calculate the statistical difference and a univariate logistic regression analysis was applied to determine the role of PNE as a risk factor for the development of each category of sleep disorders and to calculate the odds ratio (OR).

RESULTS

PNE children show a higher prevalence of all sleep disturbances (41.03% DIMS; 85.12% SBD; 63.29% DA; 67.53% SWTD; 31.28% DOES; 37.92% SHY; 25.33% SDSC total score), and according to OR results (SDSC total score OR = 8.293, 95% confidence interval [CI] = 5.079-13.540; DIMS OR = 7.639, 95% CI = 5.192-11.238; SBD OR = 35.633, 95% CI = 22.717-55.893; DA OR = 13.734, 95% CI = 9.476-19.906; SWTD OR = 14.238, 95% CI = 9.829-20.625; DOES OR = 5.602, 95% CI = 3.721-8.432; SHY OR = 6.808, 95% CI = 4.608-10.059), PNE could be considered as a risk factor for the development of sleep disorders.

CONCLUSION

Among PNE children, sleep could be strongly altered, thus helping to affirm the hypothesis that PNE tends to alter sleep architecture, or it could itself be the consequence of an abnormal sleep structure. The findings also point to the existence of a potential increase in the risk of developing sleep disorders in the presence of PNE.

Temperamental characteristics in childhood migraine without aura: a multicenter study

BACKGROUND

Children with migraine seem to be more anxious, sensitive, deliberate, cautious, fearful, vulnerable to frustration, tidy, and less physically enduring than comparisons. To the best our knowledge no studies about the temperamental and the characterial dimension aspects in childhood migraine was conducted. Therefore, the aim of the present study was to describe the temperamental and character aspects in a sample of children affected by migraine without aura (MoA) and their relationship with clinical aspects of MoA such as frequency, duration, and severity of attacks.

MATERIALS AND METHODS

In our study, 486 children affected by MoA (239 male, 247 female) aged 7-12 years, (mean 10.04 ± 2.53 years) and 518 typical developing children comparable for age (P = 0.227) and sex (P = 0.892) were enrolled to assess their temperamental characteristics. The mothers of all subjects filled out the Junior Temperament and Character Inventory: Parent Version.

RESULTS

Children affected by migraine show a higher prevalence of harm avoidance and persistence temperamental domains (P < 0.001) and significantly lower prevalence of the self-directedness character trait (P = 0.023) with respect to the comparisons, according to Cloninger's model. The Spearman rank correlation analysis shows a significant relationship between migraine characteristics and temperamental domains.

CONCLUSION

The present study first identified differences in temperamental characteristics in children affected by MoA with respect to the comparisons, suggesting the need for this evaluation in order for better psychological pediatric management of children with migraine, with possible consequences and impact on the future outcomes of these subjects.

Psychomotor approach in children affected by nonretentive fecal soiling (FNRFS): a new rehabilitative purpose

BACKGROUND

According to the Rome III criteria, encopresis without constipation was defined as nonretentive fecal soiling (FNRFS) with not yet well understood etiology. Treatment approaches reported in the literature with varying results include biofeedback, hypnosis, reflexology, and Internet-based educational programs. In developmental age, another behavioral treatment could be identified in the psychomotor approach, which is called psychomotricity in the European countries, or is also known as play therapy. The aim of the present study was to verify the safety and efficacy of play therapy plus toilet training in a small sample of prepubertal children affected by FNRFS.

MATERIALS AND METHODS

Twenty-six patients (group 1; 16 males, mean age of 5.92 ± 0.84 years) underwent a psychomotor approach therapy program in association with toilet training for 6 months, and the other 26 subjects (group 2; 17 males, mean age of 5.76 ± 0.69) underwent the sole toilet training program for 6 months. During the observational time period (T0) and after 6 months (T1) of both treatments, the patients were evaluated for FNRFS frequency and for the behavioral assessment.

RESULTS

At T0, the FNRFS mean frequency per month for group 1 was 20.115 episodes/month (standard deviation [SD] ± 3.024) and for group 2 was 20.423 (SD ± 1.879) (P = 0.661). At T1 the mean frequency per month was 6.461 (SD ± 1.333) episodes/month and 12.038 (SD ± 1.341), respectively (P < 0.001). Moreover, the delta percent average of the frequency between T0 and T1 was 67.121 ± 8.527 for group 1 and 40.518 ± 9.259 for group 2 (P < 0.001). At T1, a significant improvement in scores on the behavioral scale was identified.

CONCLUSION

Our preliminary results show the importance of a multidisciplinary approach, and suggest the positive effect of an additional psychomotor approach, as this holds a new and interesting rehabilitative purpose for children in a toilet training program, even if further research is necessary.

Attachment styles in children affected by migraine without aura

BACKGROUND

In recent years, great attention has been given to the presence of psychological problems and psychiatric comorbidity that are also present in children affected by primary headaches. The relationship between pain and attachment has been identified, and it may be that pain perception may change in relation with specific attachment styles. The aim of the present study was to assess the prevalent attachment style and verify its putative relationship and correlation with the main characteristics of migraine attacks, in school-aged children affected by migraine without aura (MoA).

MATERIALS AND METHODS

The study population consisted of 219 children (103 males, 116 females) aged between 6 and 11 years (mean 8.96 ± 2.14 years), consecutively referred for MoA compared with 381 healthy controls (174 males, 207 females; mean age 9.01 ± 1.75 years) randomly selected from schools. All the children were classified according to the attachment typologies of the Italian modified version of the Separation Anxiety Test; monthly headache frequency and mean headache duration were assessed from daily headache diaries kept by all the children. Headache intensity was assessed on a visual analog scale. The chi-square test and t-test, where appropriate, were applied, and the Spearman rank correlation test was applied to explore the relationship between the types of attachment style and clinical aspects of MoA.

RESULTS

The MoA group showed a significantly higher prevalence of type A (avoidant) attachment (P<0.001) and a significantly lower prevalence of type B (secure) attachment (P<0.001) compared with the control group. Moreover, the Spearman rank correlation analysis showed a significant relationship between MoA characteristics and the attachment style of MoA children.

CONCLUSION

The main findings of the present study were the higher prevalence among MoA children of the avoidant attachment style (type A) and the significantly lower prevalence of the secure style attachment (type B) compared with the normal controls, suggesting that the study of psychiatric comorbidity in pediatric headache may be enriched by this new aspect of analysis.

Self-concept evaluation and migraine without aura in childhood

INTRODUCTION

Self-esteem is related to the broadly understood concept of self-schemas and is a crucial mechanism for a correct psychological development in children and adolescents. The impact of the many psychological difficulties linked to the migraine without aura (MoA) and recurrent headache attacks, such as anger and separation anxiety, on self-esteem has not yet been well investigated. The aims of the present study were to assess self-esteem levels in an objective way and to verify their possible relationship and correlation with the frequency and intensity of migraine attacks, in a population of children and adolescents affected by MoA.

METHODS

The study population was comprised of 185 children (88 males [M],97 females [F]) aged between 6 and 12 years (mean 9.04 ± 2.41 years) referred consecutively for MoA to the Center for Childhood Headache, Clinic of Child and Adolescent Neuropsychiatry, Second University of Naples and of 203 healthy controls (95 M, 108 F) with mean age 9.16 ± 2.37 years, recruited from schools in Campania. The monthly headache frequency and the mean headache duration were assessed from daily headache diaries kept by all the children, and MoA intensity was assessed on a VAS (visual analog scale). To further evaluate their level of self-concept, all subjects filled out the Multidimensional Self-Concept Scale (MSCS).

RESULTS

The two study groups were comparable for age (P = 0.621), sex (P = 0.960), and z-score BMI (P = 0.102). The MoA group showed a significant reduction in the MSCS total score (P < 0.001) and in the Social (P < 0.001), Affect (P < 0.001), Family (P < 0.001), and Physical (P < 0.001) domains of the MSCS compared with the control group. The Pearson's correlation analysis showed a significantly negative relationship between MoA clinical characteristics and MSCS scores, and similarly the frequency of attacks was significantly negatively related with the Social (r = -0.3176; P < 0.001), Competence (r = -0.2349; P = 0.001), Physical (r = -0.2378; P = 0.001), and total (r = -0.2825; P < 0.001) scores of the MSCS. On the other hand, the MoA duration was significantly negatively related with the Social (r = -0.1878; P = 0.01), Competence (r = -0.2270; P = 0.002), Physical (r = -0.1976; P = 0.007), and total (r = -0.1903; P = 0.009) scores of the MSCS.

CONCLUSION

Our study first identified differences in self-esteem levels, with an objective tool, in children affected by MoA compared with controls, suggesting the need for evaluation of self-esteem for better psychological pediatric management of children with migraine.

Maternal personality profile of children affected by migraine

BACKGROUND

Empirical evidence of the important role of the family in primary pediatric headache has grown significantly in the last few years, although the interconnections between the dysfunctional process and the family interaction are still unclear. Even though the role of parenting in childhood migraine is well known, no studies about the personality of parents of migraine children have been conducted. The aim of the present study was to assess, using an objective measure, the personality profile of mothers of children affected by migraine without aura (MoA).

MATERIALS AND METHODS

A total of 269 mothers of MoA children (153 male, 116 female, aged between 6 and 12 years; mean 8.93 ± 3.57 years) were compared with the findings obtained from a sample of mothers of 587 healthy children (316 male, 271 female, mean age 8.74 ± 3.57 years) randomly selected from schools in the Campania, Umbria, Calabria, and Sicily regions. Each mother filled out the Minnesota Multiphasic Personality Inventory - second edition (MMPI-2), widely used to diagnose personality and psychological disorders. The t-test was used to compare age and MMPI-2 clinical basic and content scales between mothers of MoA and typical developing children, and Pearson's correlation test was used to evaluate the relation between MMPI-2 scores of mothers of MoA children and frequency, intensity, and duration of migraine attacks of their children.

RESULTS

Mothers of MoA children showed significantly higher scores in the paranoia and social introversion clinical basic subscales, and in the anxiety, obsessiveness, depression, health concerns, bizarre mentation, cynicism, type A, low self-esteem, work interference, and negative treatment indicator clinical content subscales (P < 0.001 for all variables). Moreover, Pearson's correlation analysis showed a significant relationship between MoA frequency of children and anxiety (r = 0.4903, P = 0.024) and low self-esteem (r = 0.5130, P = 0.017), while the MoA duration of children was related with hypochondriasis (r = 0.6155, P = 0.003), hysteria (r = 0.6235, P = 0.003), paranoia (r = 0.5102, P = 0.018), psychasthenia (r = 0.4806, P = 0.027), schizophrenia (r = 0.4350, P = 0.049), anxiety (r = 0.4332, P = 0.050), and health concerns (r = 0.7039, P < 0.001) MMPI-2 scores of their mothers.

CONCLUSION

This could be considered a preliminary study that indicates the potential value of maternal personality assessment for better comprehension and clinical management of children affected by migraine, though further studies on the other primary headaches are necessary.

Effectiveness and safety of Nintendo Wii Fit Plus™ training in children with migraine without aura: a preliminary study

BACKGROUND

Migraine without aura (MoA) is a painful syndrome, particularly in childhood; it is often accompanied by severe impairments, including emotional dysfunction, absenteeism from school, and poor academic performance, as well as issues relating to poor cognitive function, sleep habits, and motor coordination.

MATERIALS AND METHODS

The study population consisted of 71 patients affected by MoA (32 females, 39 males) (mean age: 9.13±1.94 years); the control group consisted of 93 normally developing children (44 females, 49 males) (mean age: 8.97±2.03 years) recruited in the Campania school region. The entire population underwent a clinical evaluation to assess total intelligence quotient level, visual-motor integration (VMI) skills, and motor coordination performance, the later using the Movement Assessment Battery for Children (M-ABC). Children underwent training using the Wii-balance board and Nintendo Wii Fit Plus™ software (Nintendo Co, Ltd, Kyoto, Japan); training lasted for 12 weeks and consisted of three 30-minute sessions per week at their home.

RESULTS

The two starting populations (MoA and controls) were not significantly different for age (P=0.899) and sex (P=0.611). M-ABC and VMI performances at baseline (T0) were significantly different in dexterity, balance, and total score for M-ABC (P<0.001) and visual (P=0.003) and motor (P<0.001) tasks for VMI. After 3 months of Wii training (T1), MoA children showed a significant improvement in M-ABC global performance (P<0.001), M-ABC dexterity (P<0.001), M-ABC balance (P<0.001), and VMI motor task (P<0.001).

CONCLUSION

Our study reported the positive effects of the Nintendo Wii Fit Plus™ system as a rehabilitative device for the visuomotor and balance skills impairments among children affected by MoA, even if further research and longer follow-up are needed.
