[Assessing psychopathic personality disorders for legal procedures for using a version for adolescents of Hare's revised checklist].

In accordance with Robert Hare's concept, the term psychopathy was operationalized in 1985 when the revised form of the psychopathy checklist (PCL-R) was published. Since then, the PCL-R has been used internationally. For several years in North America and now even in England and the Netherlands, personality traits of psychopathy have also been studied in children and juveniles. Based on the PCL-R, a checklist for adolescents (PCL-YV) was developed that takes the special conditions of adolescents into account. The goal of this paper was to test the applicability of the PCL-YV retrospectively in a sample of forensic psychiatric evaluations of delinquent juveniles that were assigned to the Clinic for Child and Adolescent Psychiatry at the University of Cologne, Germany. Based on results collected with the PCL-YV, data on groups of low- and medium-scoring juveniles were classified which partially differed significantly in relation to sociodemographic and anamnestic data. Furthermore, factor analyses showed a three-factor model solution. Associations with legal issues such as the question of criminal responsibility could not be found. In summary, the results indicate the applicability of the PCL-YV for adolescents but show the difficulties of retrospective design without conducting PCL interviews.

[The effectiveness of atomoxetine in children, adolescents, and adults with ADHD. A systematic overview].

This paper gives an overview of the pharmacology, efficacy, duration, tolerance, and side effects of atomoxetine for children, adolescents, and adults. A systematic analysis of the published clinical studies and poster abstracts was conducted. Atomoxetine is the first selective inhibitor of the noradrenaline transporter that was approved by the FDA in the US as a nonstimulant for the treatment of ADHD in children, adolescents, and adults. In clinical studies, its efficacy was studied in 4,000 patients. Compared with placebo, atomoxetine proved to be superior with respect to reducing impulsiveness, hyperactivity, and inattention. There are indications that its efficacy is comparable to that of methylphenidate. In general, atomoxetine was well tolerated. The most frequently reported adverse events were decrease of appetite, abdominal problems, tiredness, and vertigo. These were classified as mild and found mostly at the beginning of treatment. The existing results indicate that atomoxetine is promising for the treatment of ADHD in children, adolescents, and adults.

The principle of regulation in biology--from bone to eating behavior.

Cell physiology and molecular biology typically follow a reductionistic approach in science. In the last decade, molecular principles and pathogenetic factors involved in the development of many diseases have been successfully discovered. Therefore, early biological concepts based on systemic and cybernetic thoughts have been largely overshadowed by these more recent molecular and pathogenetic factors. This review highlights discoveries on bone development and hypothalamic controlled feeding and eating behavior with a cybernetic and systemic perspective. Interestingly, ancient ideas on bone development and hypothalamic function are still reasonable considerations to embed new molecular discoveries into a systemic concept of principles organizing nature.

[The psychopathy-concept and its psychometric evaluation in childhood, adolescence and adulthood].

The psychopathy concept in accordance with Robert Hare was operationalized in 1985 when the revised form of the Psychopathy Checklist (PCL-R) was published. Since then, the PCL-R has been used internationally in prognosis and therapy research. In North America, personality traits of psychopathy have also been studied in children and juveniles for several years by now. On the basis of the PCL-R, a checklist for adolescents (PCL-YV) was developed that takes the special conditions of adolescents into account. In juveniles with a high score research with the PCL-YV demonstrated a lack of empathy, impulsivity and social adjustment disorder. Furthermore, researchers found associations between the number and severity of violent offences, early drug abuse and earlier recidivism, i. e. repeated criminality. The biological determinants of these dimensions are discussed as well as associated questions about recent specific therapy concepts and diagnostic aspects of psychopathy in juveniles.

A cybernetic approach to osteoporosis in anorexia nervosa.

A group of 25 female individuals, who had been admitted to the University Hospital with the diagnosis of anorexia nervosa (AN) 3 to 10 years before, was seen for a follow-up visit in the hospital. These women got a psychiatric exploration to detect a present eating disorder. Moreover, parameters of the muskuloskeletal interaction were determined on the non-dominant forearm. Bone mineral content (BMC) of the radius was measured by pQCT and maximal grip force was evaluated by the use of a dynamometer. Eating disorders were present in 12 females. The mean of BMC standard deviation (SD) score was significantly reduced in comparison with reference values. Furthermore, the mean of BMC SD score was also significantly lower than the mean of grip force in SD score. These results gave the suggestion that the adaptation of bone mass to biomechanical forces is disturbed in AN. The linear regression analyses between the parameters grip force and BMC were compared between the study and the reference group. The comparison delivered a significantly lower constant in the regression equation of the study group. This result can be interpreted on the background of the mechanostat theory. The affection with an eating disorder decreases the set point in the feedback loop of bone modeling. The results offer for the first time the possibility to analyse osteoporosis in anorexic females under the paradigm of muskuloskeletal interaction.

[School truancy. A heterogeneous disturbing picture].

School truancy is not a diagnostic entity. It is rather a conglomeration of symptoms with various causal factors. With a prevalence of about 5% of all children attending school, three typical groups of anxious school truants can be differentiated: children with separation anxiety, with simple and social phobia as well as anxious and/or depressive symptoms. Anxious truants show depressive symptoms and separation anxiety significantly above chance, while school truancy is closely associated with social disorders, depression and oppositional behaviour and mostly occurs in boys. Psychosocial risk factors such as contact problems with peers, familial and school problems often play an important part. The increased comorbidity as well as various associated stress factors demand multiple behaviour and psychological diagnostics. Sophisticated therapeutic measures should regard this and focus on cognitive behaviour therapy as well as educative and supportive interventions.

[Pharmacological treatment in adults with attention deficit hyperactivity disorder].

Treatment in adults with attention deficit hyperactivity disorder predominantly relies on pharmacotherapeutic approaches especially with psychostimulants. Empirical studies indicate that their clinical effectiveness may be as high as in children and adolescents, especially in higher dosages. However, due to the high prevalence of comorbidities, e.g. depression, psychopharmacological treatment requires an extended use of other substance groups, especially antidepressants. An optimal treatment response necessitates the choice of an adequate substance depending on the leading clinical symptoms and a procedure of an individual titration of different dosages. This article reviews the current empirical results in the pharmacological treatment of ADHD in adults and provides possible treatment strategies for clinical practice.

[Disorder attribution in psychiatric problems of adolescents. A pilot study of inventory validation of disorder attribution of psychiatric problems in adolescents].

OBJECTIVES: The first Questionnaire on Disorder Concepts for Mental Problems in Adolescents (SPPJ) was developed on the basis of the attributional theory (health locus of control) and validated in a population of 54 adolescents with mental disorder hospitalized primarily as in-patients. METHODS: Analysis of consistency, correlation with the test for locus of control in health and illness (KKG-Test), scale intercorrelation, correlation with the Frankfurt Self-Concept Scales, therapy cooperation and prognosis. RESULTS: The SPPJ distinguishes between causal attributions and locus of control and proves to be a reliable measuring instrument that delivers satisfactory correlations to the statement of general measuring instruments (KKG-Test). Contrary to our expectations there is no significant positive correlation between internal locus of control and cooperation and prognosis. An external, powerful-others causal attribution has a negative effect upon cooperation, while an external powerful-others locus of control has a positive effect upon it. CONCLUSIONS: Adolescent self-assessment of mental problems is a defined research subject different from illness or health concept variables in adults or concerning bodily illness. Adolescents who are less inclined to blame others for their problem and who value professional competence are probably more accepting of interventions and more compliant. Further research in this area is necessary. On the basis of the attributional theory more attention must be paid to the substantial difference between locus of (treatment) control and causal attributions.

[Sleep disorders in hyperkinetic children--correlation with arousal disorders, differential diagnosis and comorbidity].

OBJECTIVES: Sleep disorders are frequently observed in Attention Deficit-Hyperactivity Disorder (ADHD). At the same time, however, there is little evidence of their prevalence and their specific characteristics. Also unclear is a possible pathogenetic relationship between disturbed sleep and the core symptoms of ADHD. There are still very few findings on the role of comorbid internal and neurological disorders like sleep apnea and restless legs syndrome in the differential diagnosis of ADHD. METHODS: We present an overview of the current literature, describing the most important results concerning sleep disorders in ADHD. RESULTS: A principal goal of future assessments is to ascertain whether sleep problems in children with ADHD represent unspecific concurrent symptoms or whether they play a substantial role in the pathogenesis of ADHD. CONCLUSIONS: Moreover a possibly increased risk of comorbid sleep-disordered breathing disorder might be an important issue in the differential diagnostic considerations with regard to ADHD.

Behavioural problems in children and adolescents with spinal muscular atrophy and their siblings.

Spinal muscular atrophy (SMA) is a chronic illness characterized by loss of motor function. The aim of the study was to investigate behavioural adjustment in 96 children and adolescents with SMA (47 males, 49 females; mean age 11 years 2 months, range 6 to 18 years). Forty-five non-affected siblings (26 males, 19 females; mean age 11 years 6 months, range 6 to 18 years) and 59 normally developing children (33 males, 26 females; mean age 10 years 8 months, range 6 to 18 years) were recruited as control participants. Behavioural symptoms were measured with the Child Behaviour Checklist (CBCL) and disorders were assessed with a structured psychiatric interview (Kinder-DIPS). Of the patients with SMA, 12.5% fulfilled the criteria for an ICD-10 or DSM-IV diagnosis, with separation anxiety disorder being the most common diagnosis. The CBCL total score was in the clinical range for 11.5% of patients, 20% of the siblings, and 11.7% of the control children; the externalizing score rates were 2.1%, 22.2%, and 11.9% respectively; the internalizing score 18.9%, 24.4%, and 13.6% respectively. Comorbid psychopathology was not influenced by sex, IQ, nor severity of SMA, and only externalizing behaviour was correlated to age. In conclusion, children and adolescents with SMA are characterized by a low psychiatric comorbidity not different from control individuals. The group with the highest rate of behavioural problems and with the greatest need for intervention were the non-affected siblings who had a two- to threefold higher rate of behavioural problems than the normative population.

[Child is inattentive, cannot sit still, disturbs the classroom. Is it really a hyperkinetic disorder?].

The clarification of attention-deficit/hyperactivity disorder (ADHD) requires an unequivocal categorization of the diagnostic criteria and a differentiation of the condition from normal variations and other disorder patterns. The ICD-10 criteria comprise the main symptoms inattention, hyperactivity and impulsivity. In kindergarten and preschool children, hyperactivity predominates, while in schoolchildren poor attention and cognitive impulsivity tend to be to the fore. In adolescence, aggressiveness and dissocial behavior coupled with drug abuse become central. In adulthood, ADHD is associated in particular with a tendency towards a lower social status and more frequent delinquency. Establishment of the diagnosis of ADHD requires information from the person to whom the individual relates. In this connection, exploration schemas, check lists and questionnaires are often very helpful. With regard to the differential diagnosis, mental disturbances due to physical causes (e.g. hearing disorders, epilepsy, etc.) must be excluded. Consideration must also be given in particular to comorbidities--found in up to two-thirds of cases--in which disordered social behavior, affective disorders and anxiety disturbances dominate.

[Multimodal therapy concept in hyperkinetic disorder. Drugs alone are not enough].

For the treatment of attention deficit/hyperactivity disorder, both medical and behavioral therapeutic concepts have been shown to be effective. Somewhat problematical, however, is the fact that a large percentage of these children retain residual symptoms that need treating over a longer period of time. The value of a multimodal therapeutic approach (combination of medication and behavioral treatment including counseling of parents, teachers and the patient) remains controversial. Over the long-term, and account being taken of a number of indicators extending beyond the core symptoms, however, the multimodal treatment concept would appear superior to treatment solely with psychostimulants. For effective treatment accurate titration and the recording of the changes occurring under medication are important.

Intelligence and cognitive function in children and adolescents with spinal muscular atrophy.

Spinal muscular atrophy is a chronic disease characterised by loss of motor function. The aim of the study was to analyse cognitive functions in a large group of patients with spinal muscular atrophy. It was hypothesised that their intelligence is comparable to controls, but not above average as previously postulated. Ninety-six children and adolescents with spinal muscular atrophy I-III, aged 6.0-18.11 years, 45 non-affected siblings and 59 healthy, matched controls were examined with one- (CPM/SPM), as well as multi-dimensional intelligence tests (Kaufman-ABC; Wechsler tests). The mean IQ measured with the CPM/SPM tests was 109.6 for the spinal muscular atrophy group, 107.3 for the sibs and 104.1 for the healthy controls (no significant difference). In the older children and adolescents (SPM only) the mean IQ was significantly higher for the spinal muscular atrophy patients (109.6) than for the controls (95.4). The standard score in the 'mental processing composite' scale of the Kaufman-ABC was identical in the spinal muscular atrophy group and controls (103.8). The cognitive profile was relatively homogeneous. However, the older children and adolescents did have a significantly higher verbal IQ (113.8) than controls (104.6) in the Wechsler tests. There were no significant differences in any of the tests among different grades of severity (spinal muscular atrophy types I-III). It can be concluded that children and adolescents with spinal muscular atrophy have a general intelligence in the normal range. By adolescence, environmentally mediated aspects of intelligence are higher in patients with spinal muscular atrophy. It could be speculated that the development of cognitive skills and knowledge is a creative way to compensate the many restrictions due to their physical handicap.

Psychopathology and familial stress - comparison of boys with Fragile X syndrome and spinal muscular atrophy.

BACKGROUND: Chronic illness and mental retardation are both associated with an increased rate of behavioural problems in children and with considerable emotional strain in families. The aim of the study was to analyse and compare the specific effects of two exemplary conditions on familial stress and coping. METHODS: Forty-nine boys with Fragile X syndrome (FXS) were compared with 46 boys with Spinal Muscular Atrophy (SMA) and 32 male controls. Intelligence was measured with the RAVEN or K-ABC tests. Psychopathology was assessed with the CBCL questionnaire and a structured psychiatric interview (Kinder-DIPS), parental stress with the QRS, coping with the F-COPES and social support with the F-SOZU questionnaires. RESULTS: The mean age of the FXS boys was 8.6, of the SMA boys 12.7 and of the controls 11.2 years. The mean IQ was 47 for the FXS, 112 for the SMA and 103 for the control groups. According to the CBCL, 89.8% of the FXS boys, 21.7% of the SMA and 15.7% of the controls had a total score in the borderline or clinical range. The rates were 63.3%, 34.8% and 21.9% for internalising and 67.3%, 10.9% and 18.8% for externalising behaviour, respectively. 81.6% of the FXS and 10.9% of the SMA patients had a DSM-IV or ICD-10 psychiatric diagnosis. The most common were ADHD (FXS: 36) and Separation Anxiety Disorder (SMA: 4). In total, parental stress was significantly higher in the FXS than in the SMA families (and in both compared to controls). There were no major inter-group differences regarding social support and familial coping. CONCLUSIONS: Children with FXS are severely mentally retarded and have a high rate of mainly externalising disorders. Despite good coping abilities and social support, this is associated with high familial stress. The SMA boys, with an intelligence in the upper normal range, are no more deviant than their healthy controls. Parental stress is lower in the SMA families with good coping abilities. In conclusion, families with mentally retarded children are in even greater need of help than those of children with severe chronic illness/physical handicap.

Discriminant validity of the child behaviour checklist CBCL-4/18 in German samples.

This study examined the discriminant validity of the German version of CBCL in two large samples of referred and non-referred children and adolescents which were matched for age, sex and socio-economic status. The combined sample that was used for statistical analysis consists of 2,058 referred and 2,058 non-referred boys and girls between 4 and 18 years of age (mean age: referred boys= 10.9 years, non-referred boys = 10.9 years, referred girls=11.3 years, non-referred girls=11.1 years). Referral status was used as validity criterion. Statistical procedures included Odds Ratios, Total Predictive Values, ROC analyses and discriminant analyses. Results indicated that the discriminant validity of the German version of CBCL is comparable to the original English version. With the use of CBCL Total Problem Score as predictor (cut-off T > or = 60) 83.8% of children and adolescents could correctly be classified (sensitivity 83.6%, specificity 83.9%). Symptoms of the "Attention Problems Scale" show the highest discriminative power to distinguish between disturbed and undisturbed children and adolescents.

Pericardial effusions in anorexia nervosa.

Anorexia nervosa is an eating disorder that may be accompanied by cardiac symptoms of varying severity. So far disturbances like arrhythmias, mitral valve prolapse and loss of cardial ventricle mass have been described. Other somatic complications consist of electrolyte and acid-base imbalances, which in turn influence cardiac function. Between 1990 and 1999 we observed ten case reports from inpatient anorexic female adolescents, who developed pericardial effusions in the course of their illness. The diagnosis and course was revealed by echocardiography. No signs of heart failure could be noticed. In eight patients pericardial effusion remitted completely or partly by a concurrent increase in weight. A distinct pathophysiology for the development of pericardial effusion could not be revealed, but a correlation to restoration of weight seems to exist. Our report suggests that pericardial effusions are more frequent cardiac complications in anorexia nervosa than previously known. In most cases the clinical significance is doubtful.
