Abstract
Obsessive-compulsive disorder (OCD) is an extremely common form of child and adolescent psychopathology. Obsessive-compulsive disorder in children and adolescents has garnered a significant amount of attention from mental health practitioners and mental health researchers over the past decades. In order to provide a comprehensive account of this attention, the phenomenology, theoretical perspectives, empirical literature and interventions used to treat OCD in children and adolescents are reviewed in this paper. While by no means an exhaustive review, the information presented in this paper provides health and mental health professionals interested in OCD in children and adolescents with the knowledge required to enhance their understanding of this complicated form of child and adolescent psychopathology.

Abstract
Zusammenfassung. Die Komplexität von Zwangsstörungen macht eine umfassende Diagnostik erforderlich. Die Diagnostik von Zwangsstörungen ist in eine multimodale Verhaltens- und Psychodiagnostik integriert, die eine detaillierte Erfassung der individuellen Zwangssymptomatik, einschließlich ihrer aufrechterhaltenden Bedingungen, Beeinträchtigungen, komorbiden Störungen und Probleme impliziert. Die spezifischen Aspekte des diagnostischen Vorgehens bei Kindern und Jugendlichen mit Zwangsstörungen sowie deren Bezugspersonen (einschließlich Beziehungsaufbau, Exploration familiärer Beziehungen, der Zwangssymptomatik sowie komorbider Auffälligkeiten des Kindes bzw. Jugendlichen und psychischer Auffälligkeiten der Bezugspersonen, Exploration eines gemeinsamen Störungskonzeptes, Behandlungsziele und Behandlungsplanung) werden dargelegt. Die deutschsprachigen spezifischen diagnostischen Verfahren, einschließlich neuer Verfahren, werden detailliert beschrieben.

Abstract
The aim of the present paper was to critically examine evidence about the benefits of cognitive-behavioural therapy (CBT) for pediatric obsessive-compulsive disorder (OCD) from controlled and single group studies, including its benefits relative to medication are critically reviewed. Selected studies were categorized by study type and by risk of bias classification. Standardized mean differences (Hedges' g or Cohen d) and, where appropriate, weighted mean difference (WMD) were calculated. All five comparison and 14 one-group studies showed a significant benefit for CBT within a wide range (ES = .78 to 4.38). Low risk of bias studies produced the lower adjusted effect sizes. The best available estimate of CBT efficacy relative to no treatment is about 1 standardized mean difference, equivalent to a treatment effect of 8 points on the Children's Yale-Brown Obsessive-Compulsive Scale. This represents a reduction in the risk of continuing to have OCD post-treatment of about 37% (95% CI 14% to 54%). Evidence from 3 studies indicates that the efficacy of CBT and medication do not differ significantly. CBT combined with medication is significantly more efficacious than non-active controls or medication alone but not relative to CBT alone. CBT should be regarded as a first line equivalent to anti-OCD medication with the potential to lead to better outcomes when combined with medication than medication alone can provide. Additional studies are needed to further clarify CBT's benefits and to investigate how it can be made more available as a treatment option for children and youth who suffer from OCD.

Abstract
BACKGROUND Little is known about the stability of obsessive-compulsive (OC) behavior during childhood. The objective of this study is to determine the developmental stability of pediatric OC behavior and the genetic and environmental influences on stability in a large population-based twin sample. METHODS Maternal and paternal ratings on the 8-item Obsessive Compulsive Scale of the Child Behavior Checklist (CBCL-OCS) on Dutch mono- and dizygotic twin pairs from 8083 families were collected at ages 7, 10, and 12 years. Using a longitudinal twin design, stability of OC behavior and genetic and environmental influences on stability were determined. Using cutoff criteria, persistent, resilient, and new onset cases were identified in this sample. RESULTS OC behavior assessed by the CBCL-OCS showed a moderate stability with phenotypic correlations of around .50 for boys and for girls. Stability of OC behavior was influenced by genetic factors, by environmental factors shared by children growing up in the same family, and by non-shared environmental factors. Stability for OCS was lower when categorical data were analyzed than when quantitative definitions were used. CONCLUSIONS OC behavior is moderately stable in childhood. Stability of OC behavior is influenced by genetic, shared, and non-shared environmental factors.

Abstract
Serotonin plays an essential role in cognition, locomotor activity, and the regulation of sleep, pain, mood, and aggression. Polymorphisms of the HTR1B gene have been implicated in a variety of psychiatric disorders including attention deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD). The objectives of this study were to: (i) expand our original investigation of the relationship between the HTR1B receptor gene and attention deficit/hyperactivity and; (ii) to investigate a possible association of obsessive behaviors/perfectionism and the HTR1B gene in a sample of 203 families with an ADHD proband. Six single nucleotide polymorphisms (SNPs) of the HTR1B receptor gene were genotyped using standard methods. Evidence for an association between the HTR1B gene and ADHD as a qualitative diagnosis, or the inattentive and hyperactive-impulsive quantitative traits was not supported by either TDT single marker analysis or haplotype analysis. In addition we did not find evidence to suggest an association between HTR1B and perfectionism in this sample of ADHD families.

Abstract
Zusammenfassung: Fragestellung: Gegenstand der Studie waren die Symptomatologie und die Komorbidität der Zwangsstörung mit Beginn im Kindes- und Jugendalter. Methodik: Untersucht wurde eine Inanspruchnahmestichprobe von 55 kinder- und jugendpsychiatrischen Patienten (29 männlich, 26 weiblich), die überwiegend stationär behandelt wurden (95%). Strukturierte diagnostische Interviews zur Erfassung von Zwangsstörung und weiteren psychischen Störungen wurden zu Befragungen von Eltern und Kind eingesetzt. Ergebnis: Das mittlere Alter bei Beginn der Zwangsstörung betrug 11,3 Jahre. Jungen waren bei Störungsbeginn etwas, aber nicht statistisch signifikant jünger als Mädchen. Zwangshandlungen bezogen sich vorwiegend auf Waschen und Sauberkeit, Kontrollieren sowie Wiederholungen, Ordnen und Zählen. Zwangsgedanken beinhalteten vor allem Verunreinigung, die Erwartung schlimmer Ereignisse, Sexualität oder Aggression. In der klinischen Behandlungsroutine wurden seltener eine gemischte Zwangsstörung mit Gedanken und Handlungen diagnostiziert als bei Anwendung strukturierter Interviews. Die Komorbiditätsrate war Elternangaben zufolge hoch (Lebenszeit-Diagnosen: 69%; aktuelle Diagnosen: 53%). Angststörungen, affektive Störungen, hyperkinetische Störungen, Störungen des Sozialverhaltens und Ess-Störungen standen im Vordergrund. Die Zwangssymptomatik war bei Patienten mit einer höheren Anzahl an komorbiden Lebenszeitdiagnosen signifikant stärker ausgeprägt. Schlussfolgerungen: Die Studienergebnisse stehen in Einklang mit denjenigen internationaler Studien. Deutlich wurde eine Methodenabhängigkeit gestellter Diagnosen. In der Subtypisierung von Patientengruppen durch Symptomdimensionen wird ein fruchtbarer Ansatz für weitere Studien gesehen.

Abstract
BACKGROUND While behavioural or cognitive-behavioural therapy (BT/CBT) is recommended as the psychotherapeutic treatment of choice for children and adolescents with obsessive-compulsive disorder (OCD), the application of BT/CBT to paediatric OCD may not be straightforward. OBJECTIVES This review examines the overall efficacy of BT/CBT for paediatric OCD, its relative efficacy against psychopharmacology and whether there are benefits in using BT/CBT combined with medication. SEARCH STRATEGY We searched CCDANCTR-Studies and CCDANCTR-References (searched on 5/8/2005), MEDLINE, EMBASE, PsycINFO, the reference lists of all selected studies and handsearched journals specifically related to behavioural treatment of OCD. SELECTION CRITERIA Included studies were randomised controlled trials or quasi-randomised trials with participants who were 18 years of age or younger and had a diagnosis of OCD, established by clinical assessment or standardised diagnostic interview. Reviewed studies included the standard behavioural or cognitive-behavioural techniques, either alone or in combination, compared with wait-list or pill placebo. DATA COLLECTION AND ANALYSIS The quality of selected studies was assessed by two independent reviewers. The primary outcomes comprised of endpoint scores on the gold standard clinical outcome measure of OCD symptoms, distress and interference (CY-BOCS) and endpoint OCD status. MAIN RESULTS Four studies with 222 participants were considered eligible for inclusion and for data extraction. Two studies showed significantly better post-treatment functioning and reduced risk of continuing with OCD at post-treatment for the BT/CBT group compared to placebo or wait-list comparisons. We suggested that the POTS 2004 result, equal to a difference of about eight points on the CY-BOCS, represented the best available estimate for the efficacy of BT/CBT relative to no treatment. (WMD -7.50; 95% CI -11.55, -3.45). Pooled evidence from two trials indicated that the efficacy of BT/CBT and medication did not differ significantly (WMD -3.87; 95% CI -8.15, 0.41). There was evidence of the benefit of combined BT/CBT and medication compared to medication alone (WMD -4.55; 95% CI -7.40, -1.70), but not relative to BT/CBT alone (WMD -2.80; 95% CI -7.55, 1.95). The rates of drop out suggested BT/CBT is an acceptable treatment to child and adolescent patients and their families. AUTHORS' CONCLUSIONS Although only based on a small number of studies, behavioural or cognitive-behaviour therapy appears to be a promising treatment for OCD in children and adolescents. It can lead to better outcomes when combined with medication compared to medication alone. Additional trials are needed to confirm these findings. In the interim, consideration should be given to the ways in which BT/CBT might be made more widely available as a treatment for OCD in children and adolescents.

Abstract
Several lines of evidence suggest a meaningful association between obsessive-compulsive disorder and Tourette syndrome, including comorbidity, phenomenologic overlap, evidence from family and genetic studies, and the possible role of basal ganglia circuitry in both conditions. Obsessive-compulsive behaviors occur frequently in patients who have Tourette syndrome and tend to have a later onset than tics. Despite commonalities, the approaches to treating tics and obsessive-compulsive symptoms are actually quite distinct. A specialized form of cognitive behavior therapy and pharmacotherapy with a potent serotonin reuptake inhibitor are the two established first-line therapies for obsessive-compulsive disorder. An adequate trial of a serotonin reuptake inhibitor is 10 to 12 weeks in duration at doses near the upper end of the recommended range for age and weight. Cases of obsessive-compulsive disorder that do not sufficiently improve with serotonin reuptake inhibitors might benefit from adjunctive low-dose antipsychotic (eg, risperidone) medication whether or not tics are present. Warnings about an increased risk of suicidality among children and adolescents taking antidepressants for pediatric depression extend to those taking the medications for obsessive-compulsive disorder, but the risk-to-benefit ratio is more favorable in this latter population because several serotonin reuptake inhibitors have been shown to be efficacious in obsessive-compulsive disorder.

Abstract
The available literature indicates that OCD affecting children and adolescents is highly prevalent. Pediatric-onset OCD seems to share important similarities with the adult disorder but also shows important differences. For example, the clinical phenotype of OCD is remarkably consistent at all ages with some allowances for developmental expression. Pediatric patients frequently demonstrate poor insight into the nature of their obsessions, which in association with their limited verbal expression may make the diagnosis more difficult. Obsessions involving fear of harm and separation, compulsions without obsessions, and rituals involving family members are more common in younger patients. Treatment response,including serotonergic specificity and the need for robust dosing, is another feature shared by early- and adult-onset OCD. Imporfant differences across the life span can also be identified. Perhaps the clearest difference pertains to age of onset. Age-at-onset data have shown a bimodal distribution of age of onset of OCD, with one peak in preadolescent childhood and another peak in adulthood. Another distinction between child and adult OCD is gender representation. Whereas adult studies report equal gender representation or a slight female preponderance, pediatric clinical samples are clearly male predominant. Patterns of psychiatric comorbidity in pediatric OCD show high rates of tic and mood and anxiety disorders, similar to the patterns in adults, but also show a distinct association with disruptive behavior disorders (ADHD and oppositional defiant disorder) and other specific and pervasive developmental disorders. Family studies indicate that the disorder is highly familial and that a childhood onset of the disorder seems to be associated with a markedly increased risk for familial transmission of OCD, tic disorders, and ADHD. Both scientifically and clinically, the recognition of developmentally specific OCD phenotypes may be valuable. For example, research efforts aimed at identifying OCD-associated genes are likely to be more successful if developmentally homogeneous samples are studied instead of combining data from children, adolescents, and adults, as has been common in OCD studies. Clinical management is also informed by an appreciation of the unique cor-relates of OCD affecting youth, especially comorbidity with chronic tic dis-orders and ADHD and their impact on treatment. The so-called "spectrum disorders" related to OCD are less prominent in children and adolescents than in adults. Although sharing some features with typical OCD, these symptoms are less clearly ego-dystonic and less anxiety producing, frequently provide a measure of gratification, and are less responsive in general to SSRIs. Often cognitive antecedents to these behaviors are less well developed than in more typical OCD, and behavioral interventions are the mainstay of treatment but with more variable success.

Abstract
OBJECTIVE The aim of this study was to study agreement between clinician-rated measures and self-report measures previously used in epidemiologic studies to identify obsessive-compulsive disorder (OCD) in youth and to determine the adequacy of self-report measures as screening instruments. METHOD Leyton Obsessional Inventory-Child Version (LOI-CV) survey form self-report and Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) clinician-report measures were compared in a sample of 81 OCD-affected youths diagnosed using structured diagnostic interviews and the best-estimate method. Sensitivities and agreement between tests are determined for different cutoff scores. RESULTS The LOI-CV survey form total (item+interference) score is correlated with KSADS-E OCD severity (r=0.37, p=0.001) but not clinician-rated GAF scores (r=-0.18, p=0.12). LOI-CV survey form sensitivities at cutoff scores of 15, 20, 25, and 30 are 55%, 36%, 28%, and 19%, respectively. CY-BOCS scores are correlated with subject-rated interview severity (p<0.001) and clinician-rated GAF scores (p<or=0.05). CY-BOCS sensitivities at cutoff scores of 8, 10, 12, and 14 are 100%, 99%, 98%, and 90%. The cutoff scores required for greater than 95% sensitivity of the LOI-CV survey form and the CY-BOCS, respectively, are 2 and 12. LOI-CV survey form total scores do not correlate with CY-BOCS total or obsession subscores (p>or=0.03), but correlate with the CY-BOCS compulsion subscore. CONCLUSIONS The clinician-rated CY-BOCS measure using parent and child reporting performs superiorly to the subject-rated LOI-CV measure using child reporting to identify pediatric OCD in a clinically referred population. Because self-report measures have been used in epidemiological studies, youth OCD prevalence rates may be higher than previously reported.

Abstract
OBJECTIVES To determine the prevalence of obsessive--compulsive behaviours (OCB) in a clinical sample of children with attention-deficit hyperactivity disorder (ADHD) and to compare ADHD children (with and without OCB) with respect to clinical and cognitive characteristics and risk factors. METHOD We compared ADHD children (n = 134) with and without OCB, and we compared all ADHD children with a group of normal control subjects (n = 26) on various clinical, cognitive, and inhibitory control measures; neurobiological and psychosocial risk factors; and family histories of psychiatric illness. RESULTS Clinically significant OCB was identified in 11.2% (15/134) of children with ADHD. Comorbid OCB was associated with significantly increased perfectionism, improved teacher ratings of inattention, and a decreased likelihood of having a first-degree relative with ADHD. Comorbid ADHD and OCB may also be associated with increased oppositional behaviour at home and better inhibitory control, though these differences were not statistically significant. CONCLUSIONS Comorbid OCB is common in clinically referred children with ADHD and is associated with increased impairment relative to ADHD alone. Further, children with ADHD and OCB may develop symptoms as the result of different genetic and environmental risk factors, compared with children with ADHD only.

Abstract
Our objective was to evaluate the scope and clinical correlates of psychotic phenomena in psychiatrically referred children and adolescents. Subjects were 1657 psychiatrically referred youth (mean age = 10.9 years) evaluated from 1991 to 2002. DSM-III-R diagnoses were obtained through maternal report by using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Epidemiologic Version. Childhood-onset psychosis was defined by the presence of delusions or hallucinations. Childhood-onset psychosis was identified in 8% of psychiatrically referred youth. It was associated with a chronic course and high levels of impairment. Comorbidity with disruptive, mood, and anxiety disorders was very severe, with only one of the 132 identified youth with psychosis not having at least one comorbidity. In conclusion, childhood-onset psychosis in referred youth is common and highly morbid. It remains an important topic of research deserving full clinical and scientific attention.

Abstract
The amygdala is believed to be highly relevant to the pathophysiology of obsessive-compulsive disorder (OCD) given its prominent role in fear conditioning and because it is an important target of the serotonin reuptake inhibitors (SRIs), the pharmacotherapy of choice for OCD. In the present study, we measured in vivo volumetric changes in the amygdala in pediatric patients with OCD following 16 weeks of monotherapy with the selective SRI, paroxetine hydrochloride. Amygdala volumes were computed from contiguous 1.5 mm magnetic resonance (MR) images in 11 psychotropic drug-naive patients with OCD prior to and then following treatment. Eleven healthy pediatric comparison subjects also had baseline and follow-up scans, but none of these subjects received medication. Patients demonstrated significant asymmetry of the amygdala (L>R) prior to pharmacologic intervention in contrast to healthy comparison subjects who showed no asymmetry at the time of their baseline scan. Mixed model analyses using age and total brain volume as time varying covariates indicated that left amygdala volume decreased significantly in patients following treatment. The reduction in left amygdala volume in patients correlated significantly with higher paroxetine dosage at the time of the follow-up scan and total cumulative paroxetine exposure between the scans. No significant changes in either right or left amygdala volume were evident among healthy comparison subjects from the baseline to the follow-up scan. These preliminary findings suggest that abnormal asymmetry of the amygdala may play a role in the pathogenesis of OCD and that paroxetine treatment may be associated with a reduction in amygdala volume.

Abstract
Although obsessive-compulsive disorder (OCD) is a chronic and oftentimes debilitating disorder, the specific impact of this illness on the psychosocial functioning of affected youngsters has not been systematically described. A total of 151 clinic-referred youngsters (mean age 11.8 years, 57% male, 83% Caucasian) with primary Diagnostic and Statistical Manual of Mental Disorders (fourth edition) OCD and a primary caretaker completed a checklist designed to assess the impact of OCD on school, social, and family functioning. The two most common OCD-related problems were concentrating on schoolwork and doing homework. Consistent with the heterogeneous nature of OCD, subjects exhibited a broad range of specific impairments. However, almost 90% of youngsters reported at least one significant OCD-related dysfunction, and close to half reported significant OCD-related problems at school, home, and socially. Parents were more likely to report significant impairments in home and school functioning than children. However, few systematic gender or age effects were noted. Impairment ratings were significantly correlated with clinician-generated measures of OCD severity. These results provide the most specific description to date of the adverse impact of OCD on child psychosocial functioning. Given the adverse developmental consequences of psychosocial dysfunction, treatment studies need to carefully track and address OCD-specific functional impairments in affected youngsters.

Abstract
Anxiety disorders are common disorders in childhood, and developmental differences must be considered when diagnosing and treating patients in this age group. Recent research has illuminated the course of childhood anxiety disorders, including how they can be precursors to continued anxiety and mood problems in adulthood. Recent studies of cognitive-behavioral therapy, the first-line psychosocial treatment for childhood anxiety, have focused on the following issues: the relative efficacy of group versus individual cognitive-behavioral therapy; the role of parent involvement; and the application of specific techniques to certain diagnostic groups (eg, social skills techniques in social phobia). Selective serotonin reuptake inhibitors have been associated with high acute response rates in controlled studies of children with anxiety disorders, and more recent evidence suggests they are efficacious and well tolerated when taken for longer periods. This article will review significant diagnostic and developmental issues, and highlight recent studies in psychosocial and pharmacologic therapies of pediatric anxiety disorders.

Abstract
This case report outlines the cognitive-behavioral treatment of obsessive-compulsive disorder in a 7-year-old female with Asperger syndrome. Interventions were based upon the work of March and Mulle and were adapted in light of the patient's cognitive, social, and linguistic characteristics. Obsessive-compulsive symptoms improved markedly after approximately 6 months of treatment. Issues regarding symptom presentation, assessment, and treatment of a dually diagnosed patient are discussed.

Abstract
Current pharmacological treatment of obsessive compulsive disorder involves the use of selective serotonin reuptake inhibitors (SSRIs). However, a large proportion of patients does not respond fully to these medications despite receiving optimal doses and concomitant cognitive-behavioral therapy. Finding efficacious augmentation strategies has become an important goal of researchers and clinicians working with this population. In this case series, we describe four patients with childhood-onset obsessive compulsive disorder, and with partial or no response to SSRI treatment, who subsequently had a reduction of their symptoms with Adderall augmentation.

Abstract
BACKGROUND Rats treated chronically in a large, open field with the dopamine D2/D3 receptor agonist quinpirole (QNP) develop compulsive checking behavior as defined by a set of behavioral criteria. This paradigm has been suggested as an animal model of obsessive-compulsive disorder (OCD). Because nicotine blocks various behaviors induced by ontogenetic QNP administration, we asked whether nicotine could attenuate QNP-induced compulsive checking. METHODS Adult male Long-Evans rats (n = 14/group) were treated twice weekly with saline (control), or with QNP (0.5 mg/kg) for 14-16 injections. On the last two injections, rats were pretreated in random order with an acute dose of nicotine (0.3 mg/kg base) or saline 10 min before administration of QNP or saline; and the effects on checking behavior was examined. The effects of chronic QNP treatment on nicotinic receptors in discrete brain regions were also determined. RESULTS Chronic QNP resulted in compulsive checking and increases in cerebellar alpha4beta2 and alpha7 nicotinic receptor densities. Nicotine pretreatment significantly reduced one of the three measures of compulsive checking behavior. CONCLUSIONS Nicotine attenuates some symptoms of compulsive checking in a rat model of OCD; however, the mechanisms of this effect and therapeutic efficacy of nicotinic agonists in OCD require further study.

Abstract
OBJECTIVE This study assesses the efficacy and tolerability of fluoxetine in the acute treatment of child and adolescent obsessive-compulsive disorder (OCD) during a 13-week, double-blind, placebo-controlled study. METHOD Eligible patients aged 7 to 17 (N = 103) were randomized at a ratio of 2:1 to receive either fluoxetine or placebo. Dosing was initiated at 10 mg daily for 2 weeks, then increased to 20 mg daily. After 4 weeks of treatment, and again after 7 weeks of treatment, non-responders could have their dosage increased by 20 mg daily, for a maximum possible dosage of 60 mg daily. Primary measure of efficacy was improvement in OCD symptoms as measured by the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). All analyses were intent-to-treat. RESULTS Fluoxetine was associated with significantly greater improvement in OCD as assessed by the CY-BOCS (p = .026) and other measures than was placebo. Fluoxetine was well tolerated and had a rate of discontinuation for adverse events similar to that of placebo (p = 1.00). CONCLUSIONS Fluoxetine 20 to 60 mg daily was effective and well tolerated for treatment of OCD in this pediatric population.

Abstract
The objective of this study was to assess the extent of referral bias by comparing children and adolescents with Obsessive Compulsive Disorder (OCD) ascertained through a specialized pediatric OCD and a general child psychiatry clinic. Subjects were juveniles meeting DSM-III-R and DSM IV criteria for OCD referred to a general pediatric psychopharmacology clinic and to a specialized OCD clinic within the same academic medical center. Subjects were evaluated clinically and with structured diagnostic interviews using the Kiddie SADS-E. OCD was identified in 8.6% of the general psychiatry clinic subjects. The only differences between ascertainment sources in clinical or sociodemographic characteristics of OCD subjects were higher rates of social phobia and ADHD in the non-specialized clinic, while specialty clinic subjects had a greater lifetime severity of OCD and were more likely to have received treatment of their OCD. Because we found limited evidence for referral biases, our results suggest that findings from studies using either of these sources may generalize to the other. It also suggests that pooling subjects from the two sources is justified. Nevertheless, because some group differences did emerge, researchers should acknowledge referral bias as a potential limitation of their work.

Abstract
Obsessive-compulsive disorder (OCD) holds a particular interest for child psychiatrists because of the high proportion of cases with onset in childhood and adolescence. Over the last two decades, substantial progress has been made in describing OCD in children and adolescents and in developing and implementing effective treatments. In addition, research on the phenomenology, neurobiology, and psychopharmacology of OCD has led to its current conceptualization as a developmental neuropsychiatric disorder. In this article, the fourth in a series on OCD, the authors summarize the most recent data on the phenomenology, etiology, neurobiology, and treatment of OCD in children and adolescents.

Abstract
The common denominator of anxiety disorders is that they share inappropriate levels of emotions and cognitions that affect rather than enable adaptive behaviours. The variety of symptoms include 'spontaneous' panic attacks with mental and physical symptoms, stimulus bound anxiety associated with avoidance behaviour, and almost constant 'generalized' anxious feelings. According to the DSM-IV criteria the anxiety disorders are classified as shown in Table I.

Abstract
Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS) is a relatively new diagnostic construct applied to children or adolescents who develop, and have repeated exacerbations of, tic disorders and/or obsessive-compulsive disorder following group A beta-hemolytic streptococcal infections. The proposed pathophysiology is that the group A beta-hemolytic streptococcal bacteria trigger antibodies that cross-react with the basal ganglia of genetically susceptible hosts leading to obsessive-compulsive disorder and/or tics. This is similar to the etiologic mechanisms proposed for Sydenham's chorea, in which group A beta-hemolytic streptococcal antibodies cross-react with the basal ganglia and result in abnormal behavior and involuntary movements. When first proposed, there was much controversy about the idea that streptococcal infections were etiologically related to rheumatic fever. In a like manner, discussion has arisen about the concept of infection-triggered obsessive-compulsive disorder and tic disorders. We review the historical background to these controversies, give an update on the findings provided by research on PANDAS, and address areas of future study.

Abstract
The constellation of motor and vocal tics and certain of the other neuropsychiatric symptoms seen in Tourette syndrome are thought to have an organic basis, although the nature of the neurobiological lesion is uncertain. The syndrome is usually familial but the presumed genetic substrate has not been identified. A number of models currently under debate include a proposed autoimmune contribution.
