The management of ADHD in children and adolescents: bringing evidence to the clinic: perspective from the European ADHD Guidelines Group (EAGG).

ADHD is the most common neurodevelopmental disorder presenting to child and adolescent mental health, paediatric, and primary care services. Timely and effective interventions to address core ADHD symptoms and co-occurring problems are a high priority for healthcare and society more widely. While much research has reported on the benefits and adverse effects of different interventions for ADHD, these individual research reports and the reviews, meta-analyses and guidelines summarizing their findings are sometimes inconsistent and difficult to interpret. We have summarized the current evidence and identified several methodological issues and gaps in the current evidence that we believe are important for clinicians to consider when evaluating the evidence and making treatment decisions. These include understanding potential impact of bias such as inadequate blinding and selection bias on study outcomes; the relative lack of high-quality data comparing different treatments and assessing long-term effectiveness, adverse effects and safety for both pharmacological and non-pharmacological treatments; and the problems associated with observational studies, including those based on large national registries and comparing treatments with each other. We highlight key similarities across current international clinical guidelines and discuss the reasons for divergence where these occur. We discuss the integration of these different perspective into a framework for person/family-centered evidence-based practice approach to care that aims to achieve optimal outcomes that prioritize individual strengths and impairments, as well as the personal treatment targets of children and their families. Finally, we consider how access to care for this common and impairing disorder can be improved in different healthcare systems.

Clinical and Neuropsychological Predictors of Methylphenidate Response in Children and Adolescents with ADHD: A Naturalistic Follow-up Study in a Spanish Sample.

BACKGROUND: Methylphenidate (MPH) is the most commonly used medication for Attention-Deficit/Hyperactivity Disorder (ADHD), but to date, there are neither consistent nor sufficient findings on conditions differentiating responsiveness to MPH response in ADHD. OBJECTIVE: To develop a predictive model of MPH response, using a longitudinal and naturalistic follow-up study, in a Spanish sample of children and adolescents with ADHD. METHODS: We included all children and adolescents with ADHD treated with MPH in our outpatient Clinic (2005 to 2015), evaluated with the K-SADS interview. We collected ADHD-RS-IV.es and CGI-S scores at baseline and at follow up, and neuropsychological testing (WISC-IV, Continuous Performance Test (CPT-II) & Stroop). Clinical response was defined as >30% reduction from baseline of total ADHD-RS-IV.es score and CGI-S final score of 1 or 2 maintained for the previous 3 months. RESULTS: We included 518 children and adolescents with ADHD, mean (SD) age of patients was 11.4 (3.3) years old; 79% male; 51.7% had no comorbidities; and 75.31% had clinical response to a mean MPH dose of 1.2 mg/kg/day. Lower ADHD-RS-IV.es scores, absence of comorbidities (oppositional-defiant symptoms, depressive symptoms and alcohol/cannabis use), fewer altered neuropsychological tests, higher total IQ and low commission errors in CPT-II, were significantly associated with a complete clinical response to methylphenidate treatment. CONCLUSION: Oppositional-defiant symptoms, depressive symptoms, and a higher number of impaired neuropsychological tests are associated with worse clinical response to methylphenidate. Other stimulants or non-stimulants treatment may be considered when these clinical and neuropsychological variables converged in the first clinical interview.

Practitioner Review: Current best practice in the use of parent training and other behavioural interventions in the treatment of children and adolescents with attention deficit hyperactivity disorder.

BACKGROUND: Behavioural interventions are recommended for use with children and young people with attention deficit hyperactivity disorder (ADHD); however, specific guidance for their implementation based on the best available evidence is currently lacking. METHODS: This review used an explicit question and answer format to address issues of clinical concern, based on expert interpretation of the evidence with precedence given to meta-analyses of randomised controlled trials. RESULTS: On the basis of current evidence that takes into account whether outcomes are blinded, behavioural intervention cannot be supported as a front-line treatment for core ADHD symptoms. There is, however, evidence from measures that are probably blinded that these interventions benefit parenting practices and improve conduct problems which commonly co-occur with ADHD, and are often the main reason for referral. Initial positive results have also been found in relation to parental knowledge, children's emotional, social and academic functioning - although most studies have not used blinded outcomes. Generic and specialised ADHD parent training approaches - delivered either individually or in groups - have reported beneficial effects. High-quality training, supervision of therapists and practice with the child, may improve outcomes but further evidence is required. Evidence for who benefits the most from behavioural interventions is scant. There is no evidence to limit behavioural treatments to parents with parenting difficulties or children with conduct problems. There are positive effects of additive school-based intervention for the inattentive subtype. Targeting parental depression may enhance the effects of behavioural interventions. CONCLUSIONS: Parent training is an important part of the multimodal treatment of children with ADHD, which improves parenting, reduces levels of oppositional and noncompliant behaviours and may improve other aspects of functioning. However, blinded evidence does not support it as a specific treatment for core ADHD symptoms. More research is required to understand how to optimise treatment effectiveness either in general or for individual patients and explore potential barriers to treatment uptake and engagement. In terms of selecting which intervention formats to use, it seems important to acknowledge and respond to parental treatment preferences.

Health care and societal costs of the management of children and adolescents with attention-deficit/hyperactivity disorder in Spain: a descriptive analysis.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental condition in childhood (5.3% to 7.1% worldwide prevalence), with substantial overall financial burden to children/adolescents, their families, and society. The aims of this study were to describe the clinical characteristics of children and adolescents with ADHD in Spain, estimate the associated direct/indirect costs of the disorder, and assess whether the characteristics and financial costs differed between children/adolescents adequately responding to currently available pharmacotherapies compared with children/adolescents for whom pharmacotherapies failed. METHODS: This was a multicenter, cross-sectional, descriptive analysis conducted in 15 health units representative of the overall Spanish population. Data on demographic characteristics, socio-occupational status, social relationships, clinical variables of the disease, and pharmacological and non-pharmacological treatments received were collected in 321 children and adolescents with ADHD. Direct and indirect costs were estimated over one year from both a health care system and a societal perspective. RESULTS: The estimated average cost of ADHD per year per child/adolescent was €5733 in 2012 prices; direct costs accounted for 60.2% of the total costs (€3450). Support from a psychologist/educational psychologist represented 45.2% of direct costs and 27.2% of total costs. Pharmacotherapy accounted for 25.8% of direct costs and 15.5% of total costs. Among indirect costs (€2283), 65.2% was due to caregiver expenses. The total annual costs were significantly higher for children/adolescents who responded poorly to pharmacological treatment (€7654 versus €5517; P = 0.024), the difference being mainly due to significantly higher direct costs, particularly with larger expenses for non-pharmacological treatment (P = 0.012). CONCLUSIONS: ADHD has a significant personal, familial, and financial impact on the Spanish health system and society. Successful pharmacological intervention was associated with lower overall expenses in the management of the disorder.

Systematic review of quality of life and functional outcomes in randomized placebo-controlled studies of medications for attention-deficit/hyperactivity disorder.

Children, adolescents and adults with attention-deficit/hyperactivity disorder (ADHD) experience functional impairment and poor health-related quality of life (HRQoL) in addition to symptoms of inattention/hyperactivity-impulsivity. To synthesize qualitatively the published evidence from randomized, double-blind, placebo-controlled trials of the effectiveness of pharmacotherapy on functional impairment or HRQoL in patients with ADHD, a systematic PubMed searching and screening strategy was designed to identify journal articles meeting pre-specified criteria. Post hoc analyses and meta-analyses were excluded. HRQoL outcomes, functional outcomes and the principal ADHD symptom-based outcome were extracted from included studies. An effect size of 0.5 versus placebo was used as a threshold for potential clinical relevance (unreported effect sizes were calculated when possible). Of 291 records screened, 35 articles describing 34 studies were included. HRQoL/functioning was usually self-rated in adults and proxy-rated in children/adolescents. Baseline data indicated substantial HRQoL deficits in children/adolescents. Placebo-adjusted effects of medication on ADHD symptoms, HRQoL and functioning, respectively, were statistically or nominally significant in 18/18, 10/12 and 7/9 studies in children/adolescents and 14/16, 9/11 and 9/10 studies in adults. Effect sizes were ≥0.5 versus placebo for symptoms, HRQoL and functioning, respectively, in 14/16, 7/9 and 4/8 studies in children/adolescents; and 6/12, 1/6 and 1/8 studies in adults. Effect sizes were typically larger for stimulants than for non-stimulants, for symptoms than for HRQoL/functioning, and for children/adolescents than for adults. The efficacy of ADHD medication extends beyond symptom control and may help reduce the related but distinct functional impairments and HRQoL deficits in patients with ADHD.

Expert recommendation: contributions to clinical practice of the new prodrug lisdexamfetamine dimesylate (LDX) in the treatment of attention deficit hyperactivity disorder (ADHD).

Attention deficit hyperactivity disorder (ADHD) is one of the most common neurobiological disorders in childhood, and is characterized by inappropriate levels of inattention, hyperactivity and/or impulsiveness, with an estimated prevalence of 5.29%. ADHD can have a negative impact upon all areas of the life of the patient. The main clinical guides accept multimodal treatment, involving both pharmacological and psychological measures, as the best management approach in ADHD (psychoeducational, behavioural and academic). Lisdexamfetamine dimesylate (LDX) is a new drug for the treatment of ADHD. A multidiscipline expert document has been developed, compiling the scientific evidence referred to this new molecule. The study also addresses the existing shortcomings in current drug therapy for ADHD and the contributions of LDX to routine clinical practice, in an attempt to help and guide physicians in the use of this new treatment. This document is endorsed by the ADHD and Psychoeducational Development task Group of the Spanish Society of Primary Care Pediatrics (Grupo de TDAH y Desarrollo Psicoeducativo de la Asociación Española de Pediatría de Atención Primaria, AEPap), the Spanish Society of Pediatric Neurology (Sociedad Española de Neurología Pediátrica, SENEP) and the Spanish Society of Out-hospital Pediatrics and Primary Care (Sociedad Española de Pediatría Extrahospitalaria y Atención Primaria, SEPEAP).

The many faces of microbiota-gut-brain axis in autism spectrum disorder.

The gut-brain axis is gaining more attention in neurodevelopmental disorders, especially autism spectrum disorder (ASD). Many factors can influence microbiota in early life, including host genetics and perinatal events (infections, mode of birth/delivery, medications, nutritional supply, and environmental stressors). The gut microbiome can influence blood-brain barrier (BBB) permeability, drug bioavailability, and social behaviors. Developing microbiota-based interventions such as probiotics, gastrointestinal (GI) microbiota transplantation, or metabolite supplementation may offer an exciting approach to treating ASD. This review highlights that RNA sequencing, metabolomics, and transcriptomics data are needed to understand how microbial modulators can influence ASD pathophysiology. Due to the substantial clinical heterogeneity of ASD, medical caretakers may be unlikely to develop a broad and effective general gut microbiota modulator. However, dietary modulation followed by administration of microbiota modulators is a promising option for treating ASD-related behavioral and gastrointestinal symptoms. Future work should focus on the accuracy of biomarker tests and developing specific psychobiotic agents tailored towards the gut microbiota seen in ASD patients, which may include developing individualized treatment options.

Development of a Short Version of the ADHD Rating Scale-IV.es (sADHD-RS-IV.es).

OBJECTIVE: To develop a short version of the Spanish 18-item ADHD-Rating Scale IV.es (sADHD-RS-IV.es) to be used as a potential screening tool in pediatric population. METHODS: We recruited 652 subjects, ages 6 to 18 (mean ± SD = 11.14 ± 3.27): 518 patients with ADHD (per DSM-IV criteria); and 134 healthy controls. We performed a stepwise logistic regression to select the best subset of ADHD-RS-IV.es items to create a short-form. We calculated internal consistency reliability (Cronbach's and ordinal alphas) and diagnostic accuracy using receiver operating characteristic (ROC) curve. RESULTS: Six items were found to enter the stepwise analysis significantly. Internal consistency was high (Cronbach's alpha = 0.86; ordinal alpha = 0.90) and offered a good concordance with clinician diagnosis and a high discriminatory power (AUC = 0.98) with an optimal cut-off at a score of six points. CONCLUSIONS: This shorter questionnaire (six items) was able to discriminate ADHD cases from healthy controls.

Data-driven subgrouping of youths with depression reveals that resilience is associated with higher physical functioning despite high symptom burden in the Texas Youth Depression and Suicide Research Network (TX-YDSRN).

BACKGROUND: The Patient-Reported Outcomes Measurement Information System (PROMIS) measure, which assesses past week status of seven domains (physical function mobility, anxiety, depressive symptoms, fatigue, peer relationships, pain interference, and pain intensity), represents a new paradigm using patient-reported outcomes. We used a data-driven approach with PROMIS to identify subgroups of youths receiving depression treatment. METHODS: Youths (n = 721) enrolled in the Texas Youth Depression and Suicide Research Network who completed the PROMIS were analyzed. Latent class analyses (LCAs) identified subgroups and compared their baseline clinical/sociodemographic features. RESULTS: Compared to population norms, our sample had worse than average physical function, anxiety, depression, fatigue, and pain interference. Using LCA, four subgroups were identified: 1) lower symptom severity and higher physical functioning (14.6 %); 2) higher symptom burden, higher pain interference/intensity, and lower physical functioning (52.7 %); 3) higher symptom burden, higher pain interference/intensity, but with higher physical functioning (9.2 %); and 4) higher symptom burden, but lower physical functioning and pain interference/intensity (23.6 %). Group 3 demonstrated higher resilience than Group 2. In contrast, Group 2 had higher anxiety than Group 4. LIMITATIONS: Individuals may have different symptom profiles due to the observational nature of the study. Replication of these subgroups may be difficult, as future samples may differ in these characteristics. Further work may demonstrate the stability of these groups. CONCLUSIONS: A data-driven analysis identified a small but significant subgroup with high physical functioning despite high symptom burden and pain, and this group reported higher resilience. Resilience-enhancing interventions may help improve functional outcomes in depressed youth.

The clinical presentation of major depressive disorder in youth with co-occurring obsessive-compulsive disorder.

BACKGROUND: Major depressive disorder (MDD) is common in youth and among the most frequent comorbid disorders in pediatric obsessive-compulsive disorder (OCD), but it is unclear whether the presence of OCD affects the symptom presentation of MDD in youth. METHODS: A sample of youth with OCD and MDD (n = 124) and a sample of youth with MDD but no OCD (n = 673) completed the Patient Health Questionnaire for Adolescents (PHQ-A). The overall and symptom-level presentation of MDD were examined using group comparisons and network analysis. RESULTS: Youth with MDD and OCD, compared to those with MDD and no OCD, had more severe MDD (Cohen's d = 0.39) and more reported moderate to severe depression (75 % vs 61 %). When accounting for demographic variables and the overall severity of MDD, those with comorbid OCD reported lower levels of anhedonia and more severe difficulties with psychomotor retardation/agitation. No significant differences in the interconnections among symptoms emerged. LIMITATIONS: Data were cross-sectional and self-reported, gold standard diagnostic tools were not used to assess OCD, and the sample size for the group with MDD and OCD was relatively small yielding low statistical power for network analysis. CONCLUSIONS: Youth with MDD and OCD have more severe MDD than those with MDD and no OCD and they experience more psychomotor issues and less anhedonia, which may relate to the behavioral activation characteristic of OCD.

When do you prescribe antidepressants to depressed children?

Major depressive disorder (MDD) in children and adolescents is a public health problem that requires evidence-based management. Our objective is to review available studies, with a PubMed search, and briefly summarize safety and efficacy results of (mostly SSRI) antidepressants in children and adolescents with MDD. Fluoxetine and escitalopram are safe and effective in the treatment of MDD in children and adolescents both in reduction of symptoms, and in remission/response rates. However, response rates are lower than for non-OCD anxiety. Sertraline also had positive results in one study that pooled results from two studies. The number needed to treat (NNT) for MDD is 10, and the number needed to harm (NNH) for suicidality is 112. Methodological limitations in the studies include, mainly, high placebo response rates, associated with multiple study sites, younger patients, and lower MDD severity. Treatment should be maintained close to 1 year after remission, to prevent relapse. FDA-approved fluoxetine and escitalopram are safe and effective in the treatment of pediatric MDD. Sertraline also has some data supporting its efficacy and safety, but is not FDA-approved. The possible modest increase in suicidal ideation in some patients should be known by clinicians, but the risk/benefit ratio is 1 to 11.2 times favorable to using SSRIs in moderate to severe MDD.

Evaluating Internet information on attention-deficit/hyperactivity disorder (ADHD) treatment: parent and expert perspectives.

BACKGROUND: The Internet is increasingly used as a source of health-related information. The objective of this study was to assess the quality of web-based information on treatments for attention-deficit/hyperactivity disorder (ADHD). METHODS: Sixteen expert health professionals in ADHD and 35 parents of paediatric patients with a recent diagnosis of ADHD assessed the information contained in the 10 highest ranked websites in Spanish, using the Spanish version of the DISCERN tool - a validated questionnaire designed to assess the quality and reliability of web-based information on treatment choices (rating scores from 15 to 75). RESULTS: DISCERN scores given by parents and experts were low (total mean scores [standard deviation]: 35.9 [13.1] and 43.4 [13.7], respectively) and inter-rater agreement was poor/moderate (weighted kappa for the global assessment between -0.69 and +0.93, average = 0.29). There was a significant change on the ADHD-knowledge and motivation for treatment (ADHD-KMT) basic knowledge sub-scale score after the assessment of the different websites by parents (total mean scores [standard deviation]: 49.09 [9.46] and 63.21 [9.45]). CONCLUSIONS: Despite a poor/moderate inter-rater agreement between parent and expert opinions, all agreed that the quality of the web-based information on treatment choices for ADHD is generally poor.

[Factors associated with adherence to pharmacological treatment of attention deficit hyperactivity disorder (ADHD): preliminary review]. / Factores asociados a la adherencia al tratamiento farmacológico del trastorno por déficit de atención e hiperactividad (TDAH): revisión preliminar.

INTRODUCTION: ADHD treatment is safe and effective, but often, adherence to t reatment is suboptimal. We studied factors associated to adherence to treatment in ADHD described in the literature. METHODS: We conducted a non-systematic bibliographic search on recent articles on medication adherence in children and adolescents with ADHD. RESULTS: There are factors associated with the disorder itself, the patient, the health system, socio-economic factors, the medication and the environment that can reduce/improve medication adherence. Some factors that improve adherence include: knowledge about ADHD, medication and its benefits and potential adverse effects. Simple, once-daily, extended-release medication regimens. Age of the patient less than 12 years and female sex. Fewer barriers to access the health system. Positive and proactive attitude of parents regarding ADHD and the use of medication. DISCUSSION: Adherence could be optimized and therefore the long-term prognosis of ADHD improved by reinforcingfactors that increase adherence, and reducing biases and ignorance about ADHD.

Introducción: El tratamiento del TDAH es seguro y eficaz, pero con frecuencia existen bajos niveles de adherencia al tratamiento. En este artículo describimos factores asociados a la adherencia descritos en la literatura disponible. Métodos: Realizamos una búsqueda bibliográfica no sistemática sobre artículos recientes sobre la adherencia a la medicación en niños y adolescentes con TDAH. Resultados: Hay factores asociados al propio trastorno, al paciente, al sistema de salud, factores socio-económicos, a la medicación y al entorno que pueden reducir o aumentar la adherencia a la medicación. Algunos factores que mejoran la adherencia incluyen: el conocimiento sobre el TDAH, la medicación y sus beneficios y efectos adversos potenciales. Regímenes de medicación sencillos, una vez al día y de liberación prolongada. Edad del paciente menor de 12 años y sexo femenino. Menos barreras de acceso al sistema de salud. Actitud positiva y proactiva de los padres respecto al TDAH y el uso de medicación. Discusión: Se podría optimizar la adherencia y por lo tanto mejorar el pronóstico a largo plazo del TDAH reforzando estos factores que aumentan la adherencia, y reduciendo los sesgos y desconocimiento sobre el TDAH.

Psychometric properties of Concise Associated Symptom Tracking (CAST) scale in youths and young adults: Findings from the Texas youth depression and suicide research network (TX-YDSRN).

Symptoms of irritability, anxiety, panic, and insomnia are common in patients with depression, and their worsening after antidepressant treatment initiation is associated with poorer long-term outcomes. The Concise Associated Symptom Tracking (CAST) scale was developed to measure these symptoms in adults with major depressive disorder (MDD). Here, we evaluate the psychometric properties of CAST in an ongoing community-based observational study involving children, adolescents, and young adults. Individuals from the ongoing Texas Youth Depression and Suicide Research Network (TX-YDSRN; N = 952) with CAST data available were included. Fit statistics [Goodness of Fit Index (GFI), Comparative Fit Index (CFI), and Root Mean Square Error of Approximation (RMSEA)] from confirmatory factor analyses were used to evaluate the five- and four-domain structure of CAST. Item response theory (IRT) analyses were also used. Individuals were grouped based on age (in years) as youths (8-17) and young adults (18-20). Correlations with other clinical measures were used to inform construct validity. Four-domain (irritability, anxiety, panic, and insomnia) 12-item structure of CAST (CAST-12) was optimal for youths (N = 709, GFI = 0.906, CFI = 0.919, RMSEA = 0.095) and young adults (N = 243, GFI = 0.921, CFI = 0.938, RMSEA = 0.0797) with Cronbach's alpha of 0.87 and 0.88, respectively. Slope of each item exceeded 1.0 on IRT analyses suggesting adequate discrimination for each item. Scores on irritability, anxiety, panic, and insomnia were significantly correlated with similar items on other scales. Together these findings suggest that CAST-12 is a valid self-report measure of irritability, anxiety, insomnia, and panic in youths and young adults.

Texas Youth Depression and Suicide Research Network (TX-YDSRN) research registry and learning healthcare network: Rationale, design, and baseline characteristics.

BACKGROUND: American youth are seriously impacted by depression and suicide. The Texas Youth Depression and Suicide Research Network (TX-YDSRN) Participant Registry Study was initiated in 2020 to develop predictive models for treatment outcomes in youth with depression and/or suicidality. This report presents the study rationale, design and baseline characteristics of the first 1000 participants. METHODS: TX-YDSRN consists of the Network Hub (coordinating center), 12 medical school "Nodes" (manage/implement study), each with 1-5 primary care, inpatient, and/or outpatient Sub-Sites (recruitment, data collection). Participants are 8-20-year-olds who receive treatment or screen positive for depression and/or suicidality. Baseline data include mood and suicidality symptoms, associated comorbidities, treatment history, services used, and social determinants of health. Subsequent assessments occur every two months for 24 months. RESULTS: Among 1000 participants, 68.7 % were 12-17 years, 24.6 % were ≥ 18 years, and 6.7 % were < 12. Overall, 36.8 % were non-Hispanic Caucasian, 73.4 % were female, and 79.9 % had a primary depressive disorder. Nearly half of the sample reported ≥1 suicide attempt, with rates similar in youth 12-17 years old (49.9 %) and those 18 years and older (45.5 %); 29.9 % of children <12 reported at least one suicide attempt. Depression and anxiety scores were in the moderate-severe range for all age groups (Patient Health Questionnaire for Adolescents [PHQ-A]: 12.9 ± 6.4; Generalized Anxiety Disorder [GAD-7]: 11.3 ± 5.9). LIMITATIONS: The sample includes youth who are receiving depression care at enrollment and may not be representative of non-diagnosed, non-treatment seeking youth. CONCLUSIONS: The TX-YDSRN is one of the largest prospective longitudinal cohort registries designed to develop predictive models for outcome trajectories based on disorder heterogeneity, social determinants of health, and treatment availability.

Antioxidant defense system and family environment in adolescents with family history of psychosis.

BACKGROUND: Our objective was to determine antioxidant defence activity in healthy controls (HC) and healthy unaffected second-degree relatives of patients with early onset psychosis (HC-FHP), and to assess its relationship with familiar environment measured using the Family Environment Scale (FES). METHODS: We included 82 HC and 14 HC-FHP aged between 9 and 17 years. Total antioxidant status, lipid peroxidation, antioxidant enzyme activities and glutathione levels were determined in blood samples. RESULTS: There was a significant decrease in the total antioxidant level in the HC-FHP group compared with the HC group (OR = 2.94; p = 0.009), but no between-group differences in the Global Assessment of Functioning (GAF) scale scores. For the FES, the HC-FHP group had significantly higher scores in the cohesion (p = 0.007) and intellectual-cultural dimensions (p=0.025). After adjusting for these two FES dimensions, total antioxidant status remained significantly different between groups (OR = 10.86, p = 0.009). CONCLUSIONS: Although causal relationships cannot be assumed, we can state that family environment is not playing a role in inducing oxidative stress in these healthy subjects. It could be hypothesized that families with affected relatives protect themselves from psychosis with positive environmental factors such as cohesion and intellectual-cultural activities.

Duloxetine in the treatment of adolescents with somatoform disorders: a report of two cases.

BACKGROUND: Our goal was to evaluate the effectiveness, safety and tolerability of duloxetine in the treatment of children and adolescents with somatoform disorder. RESULTS: We describe two cases, those of an 11-year old girl and a 17-year old boy, evaluated in our Department after being studied by a Pediatrician and Neuropediatrician due to complex physical symptoms. The evaluations to rule out medical causes were normal. We diagnosed somatoform disorder. The pharmacological treatments with antidepressants, benzodiazepines, stimulants and mood stabilizers only produced brief and partial improvement. After switching the treatment to duloxetine (30 and 60 mg/day, respectively) both patients experienced a gradual improvement that was maintained at 7 and 14 months. Conclusion. Duloxetine may be effective and well tolerated in the treatment of adolescents with somatoform disorder. Controlled trials are need.

Structural brain abnormalities in first-episode psychosis: differences between affective psychoses and schizophrenia and relationship to clinical outcome.

OBJECTIVES: Several studies have described volumetric brain abnormalities in first-episode psychosis. The extent to which these differ in patients with schizophrenia and affective psychoses, or are related to subsequent clinical outcome, is unclear. We examined volumetric magnetic resonance imaging (MRI) abnormalities in young patients with a first episode of psychosis, and compared these volumetric abnormalities in patients with schizophrenia versus affective psychosis. We then assessed whether baseline MRI abnormalities in the entire sample predicted subsequent clinical outcome. METHODS: A total of 28 adolescent patients with first-episode psychosis and 20 age-matched healthy volunteers were scanned using a 1.5 T scanner. MRI data were processed and analysed using voxel-based morphometry (VBM). We assessed clinical outcome three years after the initial scan. RESULTS: Patients had smaller grey matter (GM) volumes than controls in frontal, insular, parietal, and cerebellar cortex. Patients with an affective psychosis had greater GM volume in the right posterior cingulate than both controls and patients with schizophrenia, but less GM volume in the left cerebellum and insula. In the sample as a whole, smaller right hippocampus GM volume was associated with poor clinical outcome at three-year follow-up. CONCLUSIONS: Volumetric brain abnormalities are evident in young adults presenting with a first episode of both affective psychoses and schizophrenia, but there are also significant differences between these two patient groups. Clinical outcome after the first episode may be related to the severity of volumetric abnormalities at presentation.
