Psychopathology among parents of children and adolescents with separation anxiety disorder.

OBJECTIVE: To examine psychopathology among parents of children and adolescents with separation anxiety disorder (SAD). METHOD: A case-control design was applied: parents of children and adolescents suffering from SAD (n = 30; age: 10.7 ± 1.8 a) were compared with parents of youth without any psychiatric disease (n = 30; age: 11.2 ± 1.8 a). The SCID-I, a structured clinical interview to assess psychopathology, was applied among the parents group. RESULTS: Parents of children and adolescents suffering from SAD exhibited a significantly higher prevalence of psychopathology, mainly anxiety disorders and mood disorders, in comparison with the control group. Within anxiety disorders, mothers predominantly suffered from social phobia and specific phobia. Fathers most frequently suffered from obsessive-compulsive disorder and social phobia. Maternal anxiety disorder (current and lifetime) and maternal affective disorder (lifetime) proved to be significant predictors of SAD in youth. CONCLUSIONS: The associations between parents' psychopathology and the development of SAD in their children are discussed in the light of clinical implications, both in terms of psychotherapeutic care as well as treatment outcome.

Self-injurious behavior in adolescent girls. Association with psychopathology and neuropsychological functions.

BACKGROUND: Self-injurious behavior (SIB) is increasingly popular in psychically ill adolescents, especially in girls with posttraumatic stress (PTSD) and personality disorders. Adolescents with SIB frequently exhibit neurofunctional and psychopathological deficits. We speculated that specific neuropsychological deficits and temperamental factors could predispose patients to SIB and prospectively explored adolescent psychiatric patients with and without SIB in order to find out differences in psychopathology, and neuropsychological or temperamental factors. SAMPLING AND METHODS: Ninety-nine psychically ill adolescent girls with SIB, aged 12-19 years and treated at our clinic, were prospectively recruited during a period of 5.5 years (1999-2005). The clinical (ICD-10) diagnoses were mainly substance abuse, eating disorders, depression, PTSD and personality disorders. The control group was also prospectively recruited during the same period and consisted of 77 girls with similar diagnoses and ages but no SIB. All patients were subjected to the same selection of clinical and neuropsychological tests, mainly self-rating questionnaires and tests evaluating executive functions. RESULTS: Adolescent girls with psychiatric disease and SIB were more severely traumatized and depressed. They reported severe emotional and behavioral problems and deficits of self-regulation. In addition, their parents more frequently had psychiatric problems. Temperament, intelligence, investigated executive functions and presence of dissociative symptoms were not different in patients with and without SIB. CONCLUSIONS: We could not verify our primary hypothesis that SIB is related to specific neuropsychological deficits or temperamental factors. SIB was associated with traumatic experience, depression, problems of self-regulation and parental psychiatric disease. The prevention of SIB should therefore focus on improving affect regulation, the management of emotional distress and problem-solving strategies.

Safety and efficacy of STI-571 (imatinib mesylate) in patients with bcr/abl-positive chronic myelogenous leukemia (CML) after autologous peripheral blood stem cell transplantation (PBSCT).

We examined safety and efficacy of STI-571 in 24 bcr/abl-positive patients with CML post PBSCT. At start of STI-571 therapy, nine patients presented in blast crisis (BC) or in accelerated phase (AP), and 15 in chronic phase (CP). Patients were evaluated for hematologic, cytogenetic and molecular response, survival and toxicity. In general, STI-571 was well tolerated in this heavily pretreated group of patients with a non-hematologic and hematologic toxicity profile similar to that observed in a previous phase I trial at comparable doses. Five of nine patients with CML in transformation (AP, BC) were evaluable for hematologic response. Two of five patients had transient reductions in WBC and blasts, and three patients achieved a sustained hematologic response (>4 weeks). Cytogenetic analysis in these patients revealed numerical and/or structural responses. In CML chronic phase, STI-571 induced complete hematologic responses in all patients and major cytogenetic responses in 61% of patients with a complete cytogenetic response rate of 46%. This report indicates that STI-571 is a safe and effective drug in heavily pretreated patients. No apparent additional side-effects were noted in this patient cohort. The high rate of complete hematologic and complete cytogenetic responses in CP patients is remarkable, as intensive treatment approaches plus IFN-alpha failed to be efficient in achieving long-term stabilization of CML in this patient cohort.

Autologous transplantation of in vivo purged PBSC in CML: comparison of FISH, cytogenetics, and PCR detection of Philadelphia chromosome in leukapheresis products.

To determine the effectiveness of different methods for the detection of tumor cell contamination of collected peripheral stem cells, we performed a study on 39 chronic myelogenous leukemia (CML) patients who were consecutively treated at our department. Analyses of tumor cell contamination by fluorescence in situ hybridization (FISH), conventional cytogenetics, and polymerase chain reaction (PCR) showed marked differences in the percentage of evaluable results: Quantitative analysis of tumor cell contamination was feasible in 60 of 105 (57%) samples evaluated with the use of conventional cytogenetic analysis and in 105 of 107 (98%) samples analyzed by FISH. PCR was evaluable in all 85 samples tested (100%). Both methods were shown to be adequate overall in determining the number of BCR-ABL positive cells, although cytogenetics tended to produce slightly higher percentages. Based on these results, we conclude that FISH performed on leukapheresis products is a rapid and reliable method for assessing the quality of these products and should be used for routine evaluation of tumor cell contamination of CML stem cell products.

Self-mutilation in adolescence as addictive behaviour.

Self-mutilation as addictive behaviour has been mentioned in a few studies in recent years. We present the case of a girl with narcissistic borderline personality disorder (DSM III-R: 301.83, 301.81), who undertook multiple, repetitive self-mutilating acts. Self-mutilation is discussed as addictive behaviour in this case. We emphasize the evaluation of repetitive self-mutilating acts by applying criteria for addictive and dependence disorders, in order to achieve additional adequate strategies for treating patients showing this behaviour.

Classification of obsessive-compulsive disorder in childhood and adolescence.

OBJECTIVE: In child and adolescent psychiatry the validation of the diagnosis must be seen in the context of development. Comparing different diagnostic formulations DSM-IV and ICD-10-DCR in a clinical sample of children and adolescents suffering from obsessive-compulsive disorder (OCD) and their validation on external criteria represent such a heuristic approach. METHOD: We investigated 61 children seen consecutively in a specialized out-patient clinic for OCD. All of them were assessed by the International Diagnostic Checklists (IDCL). Diagnosis and diagnostic certainty were validated regarding age, age of onset and duration of illness. RESULTS: The agreement between the two diagnostic systems was low. The diagnostic stability of ICD-10-DCR was highly dependent on age, whereas that of the criteria DSM-IV did not depend on age and almost all subjects could be diagnosed definitely. CONCLUSION: This study suggests that the DSM-IV criteria are superior to that of ICD-10-DCR for diagnosing OCD in children and younger adolescents.

[Developmental psychological aspects of schizophrenic thinking]. / Entwicklungspsychologische Aspekte des schizophrenen Denkens.

Based on a phenomenological analysis of psychotic interpretation of the world concretism is supposed to represent an important mechanism of schizophrenic thinking: Schizophrenic concretism is the result of an ontological regression of cognitive functioning onto the archaic level of actional representation. Following Jean Piaget's theories about the children's constructions of reality a hypothesis about the structure of psychotic interpretations of the world is being proposed: In psychotic thinking the knowledge about the world is structured in an adualistic way which is characterized by an alloy of significance and notion, inner and outer world, physis and psyche. The structural similarity of psychotic thinking and thinking in early developmental stages is illustrated concretely on the basis of examples. Fundamental differences between childish and schizophrenic ways of interpreting the world will be presented, showing the specificity of cognitive representation in schizophrenic thinking.

Selection of unrelated bone marrow donors by PCR-SSP typing and subsequent nonradioactive sequence-based typing for HLA DRB1/3/4/5, DQB1, and DPB1 alleles.

HLA incompatibility between bone marrow recipients and unrelated donors is one of the main obstacles in bone marrow transplantation. HLA class I and generic class II DR and DQ typing is generally performed by serology. Precise subtyping of HLA class II genes, however, can only be achieved by molecular genetic methods. Here, the final selection of serologically pretyped unrelated bone marrow donors by confirmatory PCR-SSP (PCR-sequence-specific primers) typing and subsequent nucleic acid sequence analysis of the second exon of DRB1, DRB3, DRB4, DRB5, DQB1, and DPB1 alleles is presented. Serologically identical potential marrow donors and their corresponding recipients were analyzed for HLA-DRB identity by PCR-SSP analysis. After solid-phase single-strand separation, direct sequencing of the allele- or group-specific DRB amplified products was performed by applying fluorophorlabelled sequencing primers. Electrophoretically separated sequencing products were detected by means of an automated DNA sequencer. Group-specific amplification and sequencing of DQB1 alleles was carried out for all potential bone marrow donors and recipients, while only the final donor-recipient pair was analyzed for DPB1 alleles. Thus, the presented amplification strategy in combination with direct sequencing of PCR products allows matching of bone marrow transplant pairs with the highest degree of reliability for the assessment of HLA class II identity.

Diagnosis of headache in childhood and adolescence: a study in 437 patients.

We investigated whether the criteria for idiopathic headache published by the International Headache Society (IHS) are useful in childhood and adolescence and compared the diagnoses according to this classification with those of Vahlquist. We used a semi-structured questionnaire to examine a total of 437 children and adolescents referred consecutively to a headache outpatient clinic. Twenty-eight of 437 patients were excluded because of symptomatic or unclassifiable headache. Of 409 patients with idiopathic headache, 70.4% had definite migraine or tension-type headache (IHS 1.1, 1.2, 2.1, 2.2), 20.5% had a migrainous disorder (IHS 1.7) and 9.1% had headache of the tension-type not fulfilling the criteria (IHS 2.3). In the differential diagnosis of migraine and tension-type headache the intensity of pain, aggravation of headache by physical activity, nausea and vomiting were the most important features. The quality of pain, photo- and phonophobia were less helpful and location least important. The duration of migraine attacks was less than 2 h in 19.0% of the migraine patients. In general, the diagnostic criteria of migraine were highly specific but less sensitive, and those of tension-type headache highly sensitive but less specific. The agreement between IHS criteria and those of Vahlquist was marked (kappa = 0.57). We conclude that the IHS criteria are useful for classifying headache in children and adolescents referred to a headache outpatient clinic. A forthcoming modification of the IHS criteria should consider a reduction of the minimum duration of migraine attacks from 2 h to 1 h and should try to increase the sensitivity of the criteria for migraine and the specificity of the criteria for tension-type headache.
