Features of Primary Chronic Headache in Children and Adolescents and Validity of Ichd 3 Criteria.

Introduction: Chronic headaches are not a rare condition in children and adolescents with negative effects on their quality of life. Our aims were to investigate the clinical features of chronic headache and usefulness of the International Classification of Headache Disorders 3rd edition (ICHD 3) criteria for the diagnosis in a cohort of pediatric patients. Methods: We retrospectively reviewed the charts of patients attending the Headache Center of Bambino Gesù Children and Insubria University Hospital during the 2010-2016 time interval. Statistical analysis was conducted to study possible correlations between: (a) chronic primary headache (CPH) and demographic data (age and sex), (b) CPH and headache qualitative features, (c) CPH and risk of medication overuse headache (MOH), and (d) CPH and response to prophylactic therapies. Moreover, we compared the diagnosis obtained by ICHD 3 vs. ICHD 2 criteria Results: We included 377 patients with CPH (66.4% females, 33.6% males, under 18 years of age). CPH was less frequent under 6 years of age (0.8%; p < 0.05) and there was no correlation between age/sex and different CPH types. The risk to develop MOH was higher after 15 years of age (p < 0.05). When we compared the diagnosis obtained by ICHD 2 and ICHD 3 criteria we found a significant difference for the undefined diagnosis (2.6% vs. 7.9%; p < 0.05), while the diagnosis of probable chronic migraine was only possible by using the ICHD2 criteria (11.9% of patients; p < 0.05). The main criterion which was not satisfied for a definitive diagnosis was the duration of the attacks less than 2 h (70% of patients younger than 6 years; p < 0.005). Amitriptyline and topiramate were the most effective drugs (p < 0.05), although no significant difference was found between them (p > 0.05). Conclusion: The ICHD 3 criteria show limitations when applied to children under 6 years of age. The risk of developing MOH increases with age. Although our "real word" study shows that amitriptyline and topiramate are the most effective drugs regardless of the CPH type, the lack of placebo-controlled data and the limited follow-up results did not allow us to conclude about the drug efficacy.

Disruption of mTOR and MAPK pathways correlates with severity in idiopathic autism.

The molecular signature underlying autism spectrum disorder remains largely unknown. This study identifies differential expression of mTOR and MAPK pathways in patients affected by mild and severe idiopathic autism. A total of 55 subjects were enrolled, of which 22 were typically developing individuals and 33 were patients aged between 3 and 11 years, with autism spectrum disorder. A detailed history, including physical examination, developmental evaluation, mental health history and autism diagnostic observation schedule were performed for each patient. Components of the mTOR and MAPK signalling pathways were analysed from peripheral blood at the protein level. Patients were then stratified according to their clinical phenotypes, and the molecular profiling was analysed in relation to the degree of autism severity. In this cohort of patients, we identified increased activity of mTOR and the MAPK pathways, key regulators of synaptogenesis and protein synthesis. Specifically, rpS6, p-eIF4E, TSC1 and p-MNK1 expression discriminated patients according to their clinical diagnosis, suggesting that components of protein synthesis signalling pathways might constitute a molecular signature of clinical severity in autism spectrum disorder.

Clinical Features of Pediatric Idiopathic Intracranial Hypertension and Applicability of New ICHD-3 Criteria.

Idiopathic intracranial hypertension (IIH) is characterized by intracranial pressure >28 cmH2O in the absence of identifiable causes. Aim of this paper is to describe the clinical phenotype of pediatric IIH and to analyze the applicability of ICHD-3 criteria in comparison to the ICHD-2. We conducted a retrospective analysis of full clinical data of pediatric patients diagnosed with IIH between January 2007 and June 2018. Diagnostic evaluation included neuroimaging (all patients) and ultrasound-based optic nerve sheath diameter measurement (9 patients). Diagnosis of IIH was verified according to both ICHD-2 and ICHD-3 criteria for headache attributed to IIH, to verify the degree of concordance. We identified 41 subjects with suspected IIH; 14 were excluded due a diagnosis of secondary IH or lack of data. We therefore selected 27 subjects (age 4-15 years, mean 11). All patients presented with headache and bilateral papilloedema. Headache was daily in 22% cases, with diffuse gravative pain in 41%. In 4%, pain was exacerbated by cough, stress or tension. The most common presentation symptoms, in addition to headache, were blurred vision or diplopia (70%), vomiting (33%), and dizziness (15%). Twenty patients (74%) were obese. In 6 patients (22%) neuroimaging showed empty sella. Optic nerve sheath distension was detected in 6 out of 9 patients. Regarding the applicability of the ICHD-2 criteria, 18/27 (71%) patients have criterion A; 24/27 (89%) criterion B; 27/27 (100%) criterion C; 27/27 (100%) criterion D. When the ICHD-3 criteria were used, 27/27 (100%) fitted criterion A; 24/27 (89%) criterion B; 27/27 (100%) criterion C; and 27/27 (100%) criterion D. Our study suggests that, as compared with the ICHD-2, the new ICHD-3 criteria for headache attributed to IIH are better satisfied by pediatric patients with IIH. This is mainly due to the fact that qualitative headache characteristics are no longer considered in ICHD-3. Although the risk of under-rating the symptom of headache in IIH should not be disregarded, in pediatric population headache characteristics are usually less defined than in adults and obtaining a precise description of them is often very difficult.

Syndrome of Transient Headache and Neurologic Deficits With Cerebrospinal Fluid Lymphocitosis Should Be Considered in Children Presenting With Acute Confusional State.

BACKGROUND: Transient headache and neurologic deficits with cerebrospinal fluid lymphocytosis (HaNDL) is benign and self-limited, with neurologic deficits including sensory disturbance of one body side, aphasia, nausea/vomiting, weakness, decreased vision, homonymous hemianopsia, photophobia. Acute confusional state can rarely occur. Papilledema and intracranial hypertension have also been described. It is a rare entity mainly affecting adults; however, it has been sporadically described in children and adolescents. MAIN FINDINGS: In this clinical observational study, we describe a clinical series of three consecutive pediatric patients being diagnosed with HaNDL after presenting with altered consciousness, papilledema, and increased intracranial pressure. They all recovered without relapses. CONCLUSION: Presentation during childhood and adolescence is rare; the majority of pediatric cases presented with altered consciousness, which is infrequent in HaNDL. This may suggest that in childhood this symptom might be more common than in adults. All three patients presented with increased intracranial pressure and papilledema, thus suggesting that these aspects should be investigated in all patients presenting with this clinical pattern. Finally, all our patients began to suffer from migraine. This feature, together with the benign course of the disease, could favor the hypothesis of a migrainous pathophysiology of this syndrome, although this remains a speculative.

Features of aura in paediatric migraine diagnosed using the ICHD 3 beta criteria.

Background In children and adolescents, the prevalence rate of migraine with aura is 1.6%. Few studies concerning migraine with aura features in paediatric population have been reported. Aim The aim of our study was to investigate clinical features of aura in a retrospective cohort of children with migraine with aura. Furthermore, we studied whether the International Classification of Headache Disorder (ICHD) 3 beta version criteria could efficiently detect migraine with aura in a paediatric population. Results We included 164 patients who experienced aura associated with headache (mean age 9.92 ± 2.64 years). When the ICHD-II criteria were used, a final diagnosis of migraine with typical aura was obtained in 15.3% of patients, probable migraine with typical aura in 13.4%, and typical aura with headache in 61.8%, while in in 9.5% of patients the diagnosis was undetermined. According to ICHD-3 beta, we diagnosed migraine with typical aura in 77.7% of patients, probable migraine with typical aura in 13.4%, and an undetermined diagnosis in 9.5% (less than two attacks). Conclusion Aura features did not depend on age and were similar to those of adults. However, the headache could be difficult to classify if headache duration was considered. In this view, the ICHD-3 beta offers the advantage of not considering headache features, including pain duration, for the diagnosis of migraine with typical aura, thus making this diagnosis easier in children and adolescents.

Maternal Alexithymia and Attachment Style: Which Relationship with Their Children's Headache Features and Psychological Profile?

INTRODUCTION: A growing body of literature has shown an association between somatic symptoms and insecure "attachment style." In a recent study, we found a relationship between migraine severity, ambivalent attachment style, and psychological symptoms in children/adolescents. There is evidence that caregivers' attachment styles and their way of management/expression of emotions can influence children's psychological profile and pain expression. To date, data dealing with headache are scarce. Our aim was to study the role of maternal alexithymia and attachment style on their children's migraine severity, attachment style, and psychological profile. MATERIALS AND METHODS: We enrolled 84 consecutive patients suffering from migraine without aura (female: 45, male: 39; mean age 11.8 ± 2.4 years). According to headache frequency, children/adolescents were divided into two groups: (1) high frequency (patients reporting from weekly to daily attacks), and (2) low frequency (patients having ≤3 episodes per month). We divided headache attacks intensity into two groups (mild and severe pain). SAFA "Anxiety," "Depression," and "Somatization" scales were used to explore children's psychological profile. To evaluate attachment style, the semi-projective test SAT for patients and ASQ Questionnaire for mothers were employed. Maternal alexithymia traits were assessed by TAS-20. RESULTS: We found a significant higher score in maternal alexithymia levels in children classified as "ambivalent," compared to those classified as "avoiding" (Total scale: p = 0.011). A positive correlation has been identified between mother's TAS-20 Total score and the children's SAFA-A Total score (p = 0.026). In particular, positive correlations were found between maternal alexithymia and children's "Separation anxiety" (p = 0.009) and "School anxiety" (p = 0.015) subscales. Maternal "Externally-oriented thinking" subscale correlated with children's school anxiety (p = 0.050). Moreover, we found a correlation between TAS-20 Total score and SAFA-D "Feeling of guilt" subscale (p = 0.014). Our data showed no relationship between TAS-20 and ASQ questionnaires and children's migraine intensity and frequency. CONCLUSION: Maternal alexithymia and attachment style have no impact on children's migraine severity. However, our results suggest that, although maternal alexithymic traits have no causative roles on children's migraine severity, they show a relationship with patients' attachment style and psychological symptoms, which in turn may impact on migraine severity.

Can biological components predict short-term evolution in Autism Spectrum Disorders? A proof-of-concept study.

BACKGROUND: The clinical and pathogenetic heterogeneity of Autism Spectrum Disorders (ASD) limits our ability to predict its short- and long-term evolution. Aim of this naturalistic study was to observe the clinical evolution of very young children with ASD for 12 months after first diagnosis, in order to identify those children who might develop a more positive trajectory and understand how a wide range of biological, clinical and familial factors can influence prognosis. METHODS: Ninety-two children were characterized in terms of family history, prenatal and perinatal variables, and clinical conditions. The sample was divided into four subgroups based on the association of 22 biological, clinical and family history variables. Developmental Quotient (DQ), determined using the Psychoeducational Profile Revised (PEP-R), and symptoms severity, measured by means of the Autism Diagnostic Observation Schedule (ADOS), were evaluated at baseline (T0) and after one year (T1), while receiving treatment as usual. Changes in DQ and ADOS between baseline and follow-up and differences in the short-term evolution of the four subgroups were analyzed. RESULTS: At T1, 55.4 % of the children demonstrated some gains either of autistic symptomatology or of developmental skills. Mean ADOS score was 13.63 ± 3.67 at T0 and 10.85 ± 4.10 at T1 and mean DQ was 0.64 ± 0.14 at T0 and 0.66 ± 0.15 at T1. At follow-up, 33.7 % of the children showed an improvement in DQ and 37 % presented a less severe symptomatology, measured by means of ADOS. Overall, 15.2 % of the sample displayed major improvements both on developmental quotient and ADOS severity score; these children presented less EEG abnormalities and familial psychiatric disorders. The four subgroups, based on biological, clinical and familial variables, showed differing trends in terms of evolution. CONCLUSIONS: Categorizing very young children with ASD in terms of biological, clinical and familial variables can be instrumental in predicting short-term evolution. This exploratory study highlights the importance of a precise characterization and thorough analysis of interactions among biological and clinical variables, in order to predict the developmental evolution in children with ASD.

Effectiveness of community-based treatment on clinical outcome in children with autism spectrum disorders: An Italian prospective study.

OBJECTIVE: Little is known about outcomes of Autism Spectrum Disorders (ASDs) interventions in real-life settings. The main aim of this naturalistic study was to collect real-life data on the actual ASDs treatment practices in Italy. METHODS: A cohort of 48 children undergoing community-based interventions was observed in terms of personal and environmental characteristics, treatment typology and outcomes. RESULTS: An earlier start of treatment was associated with an improvement of autistic symptoms, independently from symptoms severity (p < 0.05), but not with improvements in terms of intelligence quotient (p = 0.8). Children belonging to lower socioeconomic status families began treatment later (48.0 months) than those belonging to middle (39.8 months) or upper (39.2 months) classes (p < 0.05), and received less hours of treatment. CONCLUSION: The study showed that ASDs interventions should be observed not only in experimental settings, but also in naturalistic environments, so to appraise the actual effectiveness of integrating different treatment methods in community settings.

Promoting Shared Decision Making to strengthen outcome of young children with Autism Spectrum Disorders: the role of staff competence.

Little is known on how the conceptual description of Shared Decision Making (SDM) accomplishes clinical practice in the context of lifetime disabilities as in particular Autism Spectrum Disorders (ASD), when intervention is long-lasting and requires constant family involvement. This study aimed mainly to investigate to what extent the staff's competence in SDM contributes to positive child and parent improvement when involving parents in Early Intensive Behavior Interventions (EIBI). It was also geared to verify whether SDM staff competence contributes to a child's treatment responsiveness. A total of 25 young children with ASD (23 male, 3 female, age range 34-92 months, mean age 51.4±13.6) were included in the study. Of these, nine children were allocated to a Parent Involvement condition accompanied by SDM Staff Training (PI-SDM), and eight children to a Parent Inclusion in Treatment Delivery Only condition without SDM Staff Training (PI-DO). Nine months treatment outcomes of severity, developmental and adaptive measures were compared to Treatment As Usual (n=8). PI-SDM was associated with improvement of autistic symptoms (p≤.05), adaptive functioning (p≤.01) and developmental outcome (p≤.01), as well as parent (p≤.05) and staff competence (p≤.001). The magnitude of outcome was inferior in the PI-PO and TAU group. A Reliable Change was identified in more than 40% of children included in PI-SDM, while PI-PO (>20%) and TAU (>12%) let to little Reliable Change and partially skill deterioration. Staff's SDM skill competence predicts reduced parental stress (ß=-.500, p≤.05) and contributes significantly to a positive treatment responder trajectory (p≤.01), besides lower severity (p≤.05), higher adaptive (p≤.01) and communication skills (p≤.05). The study indicates that parent inclusion should be conceptualized as a collaborative partnership model rather than as adherence in treatment provision, based on a target SDM staff training that may constitute an external contributor to treatment responsiveness and positive child as well as parent outcome.

Pharmacotherapy of autism spectrum disorders.

Although no pharmacological or behavioral therapy has currently proven effective for treating all core symptoms of autism, many dysfunctional behaviors may be treated pharmacologically. Drug treatments should always be part of a comprehensive management plan that includes behavioral and educational interventions, and should be focused on specific targets. Several classes of psychotropic medications have been used to decrease the wide range of "maladaptive" or "interfering" behaviors and associated medical problems that can interfere with relationships and physical health and hinder the implementation of various non-pharmacological interventions. Atypical neuroleptics have been shown to be useful in the treatment of behavioral symptoms in autism. Attention deficit and hyperactivity disorder medications may be effective for counteracting the additional features of hyperactivity and short attention span. Antiepileptic drugs and selective serotonin reuptake inhibitors have shown promising results, but there are no specific indications for them as of yet. With respect to potential drug targets, some clinical features are caused by a dysfunction in neurochemical signaling systems, and thus may improve with selective pharmacological interventions acting on specific abnormal neurobiological pathways. Recent animal studies can be useful models for understanding the common pathogenic pathways leading to autism spectrum disorders (ASDs), and have the potential to offer new biologically focused treatment options.
