[123I]beta-CIT SPECT imaging of striatal dopamine transporter binding in Tourette's disorder

OBJECTIVE

The authors examined whether subjects with Tourette's disorder have greater than normal striatal dopamine transporter densities, as suggested by previous post-mortem findings.

METHOD

Single photon emission computed tomography (SPECT) and [123I]2 beta-carbomethoxy-3 beta-(4-iodophenyl)tropane ([123I]beta-CIT) were used to assess dopamine transporter levels in five adult patients with Tourette's disorder and five age- and gender-matched healthy comparison subjects.

RESULTS

Striatal [123I]beta-CIT binding was a mean of 37% (range = 6%-79%) higher in the subjects with Tourette's disorder than in the comparison subjects, and each Tourette's disorder patient had a higher level than his or her paired comparison subject.

CONCLUSIONS

These findings corroborate post-mortem results and support the hypothesis of a dysregulation in presynaptic dopamine function in Tourette's disorder.

Guanfacine treatment of comorbid attention-deficit hyperactivity disorder and Tourette's syndrome: preliminary clinical experience

OBJECTIVE

Many children with Tourette's syndrome (TS) are handicapped more by difficulties with inattention, impulsivity, and hyperactivity than by their tics. However, stimulant medications used to treat attention-deficit hyperactivity disorder (ADHD) can exacerbate tics. Guanfacine is an alpha 2-adrenergic agonist that may have beneficial effects on attention, without the hypotensive or sedative effects of clonidine, which is often used as an alternative to stimulants.

METHOD

An open-label study of guanfacine was performed in 10 children with TS+ADHD, aged 8 to 16 years. The duration of follow-up was 4 to 20 weeks, and the majority of subjects were treated with 1.5 mg/day. Ratings of tic severity and ADHD symptoms were obtained using the Yale Global Tic Severity Scale (YGTSS), the Tic Symptom Self Report (TSSR), and the Conners Parent Rating Scale. In addition, blind Continuous Performance Tests (CPTs) were performed at baseline and at two follow-up intervals in eight subjects.

RESULTS

Guanfacine was associated with significant decreases in both commission errors (p < .02) and omission errors (p < .01) on the CPT. In addition, guanfacine caused a significant decrease in severity of motor (p < .02) and phonic (p < .02) tics as measured by the TSSR and the YGTSS, respectively. The most common side effects were transient sedation and headaches.

CONCLUSION

Guanfacine may provide a safe alternative therapy for children with ADHD in the presence of tics. Future double-blind, controlled trials should be undertaken.

Risperidone treatment of children and adolescents with chronic tic disorders: a preliminary report

OBJECTIVE

The purpose of this trial was to investigate the short-term safety and efficacy of risperidone in the treatment of chronic tic disorders in children and adolescents.

METHOD

This was an 11-week open-label trial and included seven subjects (five boys and two girls) with a mean age of 12.9 +/- 1.9 years. The sample included five patients with Tourette's syndrome and two with chronic motor tic disorder. The children were seen at baseline and for two follow-up visits. Three children had a comorbid diagnosis of obsessive-compulsive disorder (OCD).

RESULTS

Clinical response, as measured by the Yale Global Tic Severity Scale and the Children's version of the Yale-Brown Obsessive Compulsive Scale, revealed a statistically significant reduction in tic scores ranging from 26% [corrected] to 66%. One of three children with comorbid OCD showed substantial improvement; the other two subjects showed no change. The most frequent side effect was weight gain, which ranged from 8 to 14 lb.

CONCLUSIONS

Risperidone, a neuroleptic with both serotonin- and dopamine-blocking properties, appears to be effective in reducing tic frequency and intensity in children and adolescents with chronic tic disorders.

Selection and use of clinical rating instruments in child psychiatric nursing

TOPIC

The selection of appropriate clinical rating instruments and integration of their findings in child psychiatric nursing practice may not be clear.

PURPOSE

To offer guidance concerning the selection and application of clinical rating instruments

SOURCES

A review of recent literature of commonly used parent and teacher checklists, clinician-rated instruments, structured diagnostic interviews, and child self-reports.

CONCLUSION

Clinical rating scales have an important place in clinical practice and research in child and adolescent psychiatric settings. Selecting an appropriate instrument depends on the purpose, developmental level of the child, and expertise of the clinician--and requires careful consideration.

Tourette syndrome: update and review

Tourette Syndrome is a movement disorder of childhood onset, characterized by multiple motor and phonic tics. In addition to tics, some children exhibit repetitive habits and recurring thoughts, and others may manifest problems of inattention, impulsiveness, and hyperactivity. Over the past two decades there has been increased interest in Tourette Syndrome, because it provides a useful model for examining the interaction of genes and environment, as well as neurobiology and behavior. This article provides school nurses and nurses working in school-based clinics with a general review of Tourette Syndrome and associated disorders.

Clomipramine and obsessive-compulsive disorder

Clomipramine is a tricyclic antidepressant that was the first effective agent in the treatment of OCD. Its capacity to block serotonin reuptake appears to be essential to reducing the primary symptoms of OCD. Like other tricyclic agents, CMI has an array of possible side effects including gastrointestinal, autonomic, hepatic, and cardiac problems that need to be considered in the clinical management of children and adolescents treated with CMI. Evaluation of clinical response begins with the identification of target symptoms and monitoring the change in these target symptoms over time. This effort can be aided by the use of clinical rating instruments such as the Children's Yale-Brown Obsessive Compulsive Scales and, to a limited degree, drug plasma levels. Although many OCD patients manifest a positive response to CMI, some patients do not. This variation suggests that other neurochemical systems may be implicated in OCD.

Enhanced stress responsivity of Tourette syndrome patients undergoing lumbar puncture

Tourette's syndrome (TS) is a complex inherited neuropsychiatric disorder that is characterized by multiple motor and phonic tics. Stress-related fluctuations in symptom severity and medication responsiveness are common, and patients often report that tics are worsened by fatigue, emotional trauma, and anxiety. We examined the effects of lumbar puncture (LP) stress on plasma adrenocorticotropin (ACTH) and cortisol, urinary catecholamines, and self- and clinician ratings of anxiety in 13 medication-free TS patients and 10 normal controls, ages 17 to 41 years. The TS patients secreted significantly more ACTH than the normal controls in response to the stress of the lumbar puncture. Compared to the controls the TS patients had significantly greater postLP mean and postLP peak ACTH levels. The TS patients also excreted significantly more norepinephrine in the 20 hr preceding the lumbar puncture and reported higher levels of anxiety before and during the procedure than the controls. In addition, urinary norepinephrine excretion of the TS patients was significantly correlated with clinician ratings of tic severity. The results were not related to current levels of depression and anxiety. Taken together, these findings suggest that a subset of TS patients may be characterized by heightened reactivity of the hypothalamic-pituitary-adrenal axis and related noradrenergic sympathetic systems.

Steroid hormones and Tourette's syndrome: early experience with antiandrogen therapy

We report here the first use in Tourette's syndrome of the nonsteroidal androgen receptor blocking agent flutamide. One man and one woman underwent open trials of the medication, and a second man participated in a placebo-controlled, double-blind crossover trial. Improvement in tic symptoms ranged from 45 to 60%. The improvement was sustained in the woman during daily flutamide use and in one man during its intermittent use. One man's symptoms became refractory to treatment after 5 weeks of flutamide use, whereas the woman became depressed and had protracted diarrhea during her treatment.

Videotape tic counts in the assessment of Tourette's syndrome: stability, reliability, and validity

OBJECTIVE

We examined the short- and long-term temporal stability of tic counts to estimate the minimum length of videotape needed for a reliable index of overall tic activity and determined the interrater reliability and validity of tic counts based on prolonged videotape segments (> 10 minutes).

METHOD

Motor and phonic tic counts and clinician ratings were performed on 43 patients with Tourette's syndrome (TS), aged 7 to 50 years. Short-term stability was estimated by determining the mean interval-to-interval correlation of sequential equal-length segments from 30-minute videotape recordings of 20 subjects. Long-term stability was determined by correlating tic counts at 1-week (N = 14) and 2-week intervals (N = 11). In addition, tic counts were correlated with the most widely used clinical ratings of TS.

RESULTS

The short-term stability data indicated that estimates of motor and phonic tic frequencies should be based on videotape counts of at least 5 minutes' duration. Tic counts also were highly reliable and were significantly correlated with clinical ratings with the Yale Global Tic Severity Scale and the Clinical Global Impression Scale for Tourette Syndrome.

CONCLUSIONS

Standardized videotape tic counts can provide highly reliable, stable measures of tic frequencies that are moderately correlated with selected global ratings of tic severity.

Tourette's syndrome, Part II: Contemporary approaches to assessment and treatment

Clinical assessment of a child with Tourette's syndrome (TS) includes a careful review of motor and phonic tics. In addition, commonly associated problems of such as obsessive-compulsive symptoms, or symptoms of attention deficit hyperactivity disorder (inattention, impulsiveness, and overactivity) should also be evaluated. Treatment almost always includes education of the child, family, and school personnel concerning the natural history and behavioral boundaries of the disorder. Other treatment interventions depend to a great extent on the primary source of impairment. This article, the second of two parts, presents three illustrative cases and reviews current treatment interventions for children and adolescents with TS.

Tourette's syndrome, Part I: Definition and diagnosis

Tourette's syndrome (TS) is a neuropsychiatric disorder characterized by a changing repertoire of motor and phonic tics that typically begin in childhood and exhibit a fluctuating course. Obsessive-compulsive symptoms and problems of inattention, overactivity, and impulsiveness are present in some cases. Historically, TS has been viewed as a severe disorder. However, data from epidemiologic and family-genetic studies indicate that it shows a wide range of severity. This article, the first of two parts, examines the current notions concerning the origin, pathophysiology, and diagnosis of TS. The second article will present three cases and describe contemporary approaches to treatment.

Inpatient treatment of obsessive compulsive disorder in childhood: a case study

Obsessive compulsive disorder (OCD) is now recognized as a relatively common disorder that often has its onset in childhood. Both behavior modification and newly available serotonin reuptake inhibitors have shown to be beneficial in reducing the primary symptoms of OCD in adults, but behavior therapy has not been well-studied in children. This paper presents a case of a 13-year-old boy admitted to a child psychiatric inpatient service with severe OCD, psychotic features, and a history of Tourette's syndrome. The integration of standard behavior therapy techniques on a child inpatient service and barriers to implementing these techniques are discussed.

Severe disturbances in speech, swallowing, and gait following stereotactic infrathalamic lesions in Gilles de la Tourette's syndrome

A 40-year-old man with severe Gilles de la Tourette's syndrome characterized by forceful self-injurious motor tics, coprolalia, and obsessive-compulsive disorder had bilateral anterior cingulotomies and bilateral infrathalamic lesions placed stereotactically during two neurosurgical procedures. During the second procedure, the patient acutely developed a marked dysarthria. Postoperatively, he manifested a severe gait disturbance with postural instability, bradykinesia, axial rigidity, micrographia, and a profound swallowing disorder. MRI showed asymmetric (left > right) low-density areas in an infrathalamic region as well as low-density areas bilaterally in the anterior cingulate gyri. Although the patient's tic and obsessive-compulsive symptoms improved, the self-injurious motor tics along with other motor and phonic tics have recurred. The patient's speech remains largely unintelligible 8 months following the last surgical procedure, and the other neurologic deficits remain unchanged.

Steroid hormones and CNS sexual dimorphisms modulate symptom expression in Tourette's syndrome

We present our hypothesis that various steroid hormones play an important role in the symptom expression of Gilles de la Tourette's syndrome (TS) and that androgenic hormones, in particular, are likely to exacerbate symptoms of the disorder. We review the clinical evidence supporting our hypothesis. Sex steroids establish brain sexual dimorphisms early in CNS development, and we suggest mechanisms whereby androgenic and other hormonal changes later in human development might act at dimorphic brain regions to influence the natural history of TS. Finally, we discuss the various ways in which neuroendocrine studies might assist in genetic and neurobiologic research programs in TS.

Double-blind, crossover trial of fluoxetine and placebo in children and adolescents with obsessive-compulsive disorder

Rigorously designed clinical trials have demonstrated the efficacy and safety of fluoxetine in adults with major depressive disorder and obsessive-compulsive disorder (OCD) but not in patients below 18 years old. This report describes a randomized, double-blind, placebo-controlled, fixed-dose (20 mg qd) trial of fluoxetine in 14 children and adolescents with OCD, ages 8 to 15 years old; the study was 20 weeks long with crossover at 8 weeks. Obsessive-compulsive symptom severity was measured on the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) and the Clinician's Global Impression-Obsessive Compulsive Disorder scale (CGI-OCD). The CY-BOCS total score decreased 44% (N = 7, p = .003) after the initial 8 weeks of fluoxetine treatment, compared with a 27% decrease (N = 6, p = .13) after placebo. During the initial 8 weeks, the magnitude of improvement for the fluoxetine group significantly exceeded that for the placebo group as measured by the CGI-OCD (p = .01) but not by the CY-BOCS (p = .17). The most common drug side effects were generally well tolerated. The results suggest that fluoxetine is a generally safe and effective short-term treatment for children with OCD.

Behavioral treatment of children and adolescents with trichotillomania

Trichotillomania is a behavior disorder with onset generally in childhood, characterized by repetitive, compulsive pulling out of hair from the scalp, eyebrows, or other parts of the body, often leading to disfigurement. Trichotillomania tends to be persistent and is often resistant to counselling and standard psychiatric care. A systematic behavioral treatment program for children and adolescents and pilot findings with three patients are described. Methodological issues in relation to compliance and assessment are discussed. The relative safety and potential effectiveness of behavioral techniques suggest a useful role for this approach, perhaps in conjunction with pharmacological, family, and other treatment modalities.

Exacerbation of Gilles de la Tourette's syndrome associated with thermal stress: a family study

Gilles de la Tourette's syndrome (TS) is a familial disorder that is often exacerbated by stress or fatigue. Here we present a family of a TS proband that has several members with obsessive-compulsive symptoms, a bleeding disorder, and an unusual sensitivity to heat. The proband, who is affected by all of these traits, was challenged with heat or exercise in climate-controlled conditions and showed a marked increase in the frequency of tics.

Genetic epidemiology in child psychiatric nursing. Tourette's Syndrome as a model

Recent discoveries in the field of molecular biology and increased attention to genetic epidemiology have stimulated renewed interest in the genetics of psychiatric disorders. Tourette's syndrome, a neuropsychiatric disorder characterized by motor and phonic tics, is used as a model to describe the research strategies employed in the genetic epidemiology of child psychiatric disorders. The relevance of genetic research findings to child psychiatric nursing is also discussed.

Nursing diagnosis vs goal-oriented treatment planning in inpatient child psychiatry

The sharp rise in acute psychiatric beds for children and youth has opened up practice opportunities for child psychiatric nurses. But there is pressure from third party payers to reduce the length of stay on these services which increases demand for effective and efficient care. Timely evaluation, stabilization and discharge of children requires multidisciplinary teamwork. This paper considers the merit of nursing diagnosis in this setting and compares it to a method of multidisciplinary goal setting. The use of nursing diagnoses in child inpatient psychiatry carries some risk of creating parallel systems of care and isolating nurses from the treatment team.

Emergence of self-destructive phenomena in children and adolescents during fluoxetine treatment

Self-injurious ideation or behavior appeared de novo or intensified during fluoxetine treatment of obsessive-compulsive disorder in six patients, age 10 to 17 years old, who were among 42 young patients receiving fluoxetine for obsessive-compulsive disorder at a university clinical research center. These symptoms required the hospitalization of four patients. Before receiving fluoxetine, four patients had major risk factors for self-destructive behavior including depression or prior suicidal ideation or self-injury. Three hypotheses concerning the apparent association between fluoxetine and these self-injurious phenomena are discussed: (1) coincidence; (2) disorganization of vulnerable individuals secondary to drug-induced activation; and (3) a specific serotonergic-mediated effect on the regulation of aggression.

Screening child psychiatric inpatients for communication disorders: a pilot study

This study was part of a project concerned with speech and language disorders among child psychiatric inpatients. Twenty-two consecutively admitted children were screened and 10 were positive. Of these, nine were diagnosed with a speech or language delay, prevalence = 40.9 (9 of 22). A chart review of the preceding 2-year period showed that 27 of 128 admissions had been referred to the speech clinic and that 25 had positive findings, for a prevalence of 19.5% (25 of 128). The difference in the observed prevalence in these two studies was significant (chi 2 = 4.89, rho = .03). Standard clinical practice may miss some children with communication disorders (estimated sensitivity = 39%), while the new screening method shows promise (estimated sensitivity = 82%).

Obsessive compulsive disorder in children and adolescents: phenomenology and family history

Phenomenology and family history in 21 clinically referred children and adolescents with obsessive compulsive disorder are described. Each child and family participated in a standard clinical psychiatric assessment. The most frequently reported symptoms were repeating rituals, washing, ordering and arranging, checking, and contamination concerns. Controlling behaviors involving other family members were seen in 57% of the patients. Associated psychopathology was common: 38% received an anxiety disorder diagnosis; 29% received a mood disorder diagnosis; tics were observed in 24%. Fifteen (71%) of the children had a parent with either obsessive compulsive disorder (N = 4) or obsessive-compulsive symptoms (N = 11). The clinical and research implications of these findings are discussed.

A method of screening for communication disorders in child psychiatric inpatients

Research indicates that children with speech and language disorders probably are at greater risk for developing emotional and behavior problems. A retrospective review of referral patterns on a child psychiatric inpatient service suggested that some children with speech and language disorders were either being missed or referred late in their hospital stay. A four-part procedure was developed to screen children for speech or language problems at admission to a child psychiatric inpatient service. A pilot study of the new method showed promise as a screening procedure (estimated sensitivity = 81%; estimated specificity = 90%). The four-part screening method, referral guidelines and clinical implications are presented.

Developmental history collection on a child psychiatric inpatient service

This retrospective study was the first step of a larger project aimed at constructing a data collection tool to be used by child psychiatric nurses on an acute psychiatric inpatient service. A sample of 41 records was reviewed by a single reviewer using explicit criteria to determine the quality of data currently being gathered. The sample was randomly selected from 180 records of children admitted to an acute child psychiatric inpatient service in a major teaching institution. Of the 41 records reviewed, 14 had little or no information concerning the child's developmental course, and in about 50% of the charts similar information was recorded by different team members. It was noted that this service is fairly new, and no assessment tool that reflects a consensus of the multidisciplinary team is currently in use. Without a systematic method of gathering data upon admission, data collection will continue to be inconsistent and incomplete.

Psychiatrically hospitalized children: a critical review

The high cost of inpatient hospitalization and the rise in the number of private psychiatric beds for children and adolescents prompt several questions about who is using these services. To examine these issues, a review focusing on the use of psychiatric inpatient services by children was undertaken. The history of inpatient care of children is briefly outlined, recent public policies contributing to the rise in the number of psychiatric beds are considered, and findings from available studies are reviewed. We conclude that the data base is inadequate to draw many conclusions about who is using child psychiatric inpatient services. There appear, however, to be important differences in use of inpatient services according to age and perhaps by institutional type and geographic region. Suggestions for future research and some of the social policy implications are discussed as well.

Fluoxetine treatment of children and adolescents with Tourette's and obsessive compulsive disorders: preliminary clinical experience

Fluoxetine hydrochloride is the first selective serotonin uptake inhibitor introduced commercially in the United States. This report describes preliminary clinical experience with fluoxetine in 10 children and adolescents, aged 8 to 15 years, with primary obsessive compulsive disorder (OCD) or Tourette's syndrome (TS) plus OCD. In general, fluoxetine, which was administered from 4 to 20 weeks at a dosage of 10 or 40 mg per day, was well tolerated. Adverse effects included behavioral agitation/activation in four patients and mild gastrointestinal symptoms in two patients. No abnormalities were noted in the seven children who had follow-up EKGs. Five of the 10 patients (50%) were considered responders; their obsessive-compulsive symptoms decreased substantially during treatment with fluoxetine. Responder rates were similar in the primary OCD (two of four, 50%) and TS + OCD (three of six, 50%) groups. In conclusion, short-term fluoxetine administration appears to be safe in children and adolescents. Placebo-controlled trials are needed to further assess the efficacy of fluoxetine.

Adopted children in psychotherapy

Research shows that a larger than expected proportion of children in psychiatric treatment are adopted. When these children present with more pressing symptomatology, it is often difficult to determine how and when to address the adoption issue. This report provides a brief analysis of adoption from the perspective of attachment theory and family of origin theory. Case examples illustrate typical themes and dilemmas that arise in therapy. The authors conclude the report with an analysis of factors to consider in clinical decision-making and guidelines for intervention.
