Effects of development on olanzapine-associated adverse events

OBJECTIVE: Atypical antipsychotic medications are increasingly prescribed for child and adolescent patients. Relatively little information on adverse events (AEs), specifically in children or adolescents taking atypical antipsychotics, is available. METHOD: The Food and Drug Administration spontaneous AE reporting postmarketing surveillance database was queried for olanzapine until March 31, 2000. Patient exposure estimates as of the same date were provided by the manufacturer. AE complaints and exposure estimates were divided by age: children (birth-9 years), adolescents (10-19), and adults (20+). AE complaint risks per 10,000 patients exposed were calculated along with risk ratios across age groups and their 95% confidence intervals. RESULTS: Extrapyramidal syndrome complaint risks were similar across development, and tardive dyskinesia complaint risks were comparable in adolescents and adults. Overrepresented AE complaints in children included sedation, weight gain, liver function abnormalities, and tardive dyskinesia. Overrepresented AE complaints in adolescents included sedation, weight gain, liver function abnormalities, and prolactin increase. CONCLUSIONS: Extrapyramidal syndromes may be no more common in children and adolescents with olanzapine than in adults. The frequency of some other AEs may differ across development. Caution is warranted because of the likelihood of reporting bias. Similar analyses should be conducted with other atypical antipsychotics.     

Bullying in clinical high risk for psychosis participants from the NAPLS-3 cohort

Purpose

Bullying is associated with a heightened risk for poor outcomes, including psychosis. This study aimed to replicate previous findings on bullying prevalence in clinical high-risk (CHR) individuals, to assess the longitudinal course of clinical and functional variables between bullied and non-bullied CHR and the association of bullying with premorbid functioning, clinical outcome, transition to psychosis and risk of violence.

Methods

The sample consisted of 691 CHR participants and 96 healthy controls. Participants reported whether they had experienced bullying and how long it had lasted. Assessments included DSM-5 diagnoses, attenuated psychotic symptoms, negative symptoms, social and role functioning, depression, stress, premorbid functioning, and risk of violence. The bullied and non-bullied CHR groups were compared at baseline and further longitudinally on clinical and functioning variables and transition to psychosis.

Results

Bullying was more prevalent among CHR individuals than healthy controls. Bullied CHR had a higher prevalence of PTSD and more severe depression and stress at baseline than non-bullied CHR. There was no impact of bullying on clinical and functional variables over time. Bullying was not related to final clinical status or transition to psychosis. However, bullied participants had poorer premorbid functioning and a greater risk of violence.

Conclusion

While bullying may not impact the likelihood of CHR individuals to transition to psychosis, it may be a risk factor for development of the at-risk state and may be related to a greater risk of violence. Future studies should consider bullying perpetration among CHR individuals.

     

Neurobiological correlates of borderline personality disorder

Although patients with borderline personality disorder (BPD) are commonly seen in psychiatric practice, there has been far less biological research in BPD than in other psychiatric disorders. This article reviews the neurobiological research that has been performed to date in BPD and integrates the biological, psychological, and clinical findings in this disorder. BPD is best thought of in terms of dimensions rather than as a specific disorder. Each dimension has a biological profile and may be expressed differently in different patients. Four core elements are suggested to play a major role in the development of BPD: interpersonal stress, affective instability, impulsivity, and dissociation and self-injurious behavior. Genetic and environmental factors lead to brain alterations that are the basis for specific presentations of the disorder, such as self-injurious and impulsive aggressive behavior.     

Diagnostic efficiency of borderline personality disorder criteria in hospitalized adolescents: comparison with hospitalized adults

OBJECTIVE: The authors examined the diagnostic efficiency of borderline personality disorder criteria in adolescent inpatients. For comparison, diagnostic efficiency of borderline personality disorder criteria was also examined in a group of concurrently recruited adult inpatients. METHOD: Adolescents (N=123) and adults (N=106) were reliably assessed with the Personality Disorder Examination, a semistructured diagnostic interview for DSM-III-R personality disorders. Sixty-five adolescents and 50 adults met diagnostic criteria for borderline personality disorder. Conditional probabilities were calculated to determine which borderline personality disorder criteria were most efficient as inclusion criteria and as exclusion criteria. Adolescents and adults were analyzed separately, and the results were compared. RESULTS: There were no significant differences between groups with regard to the base rates of the borderline personality disorder diagnosis nor for any borderline personality disorder criterion. The best inclusion criterion for the adolescents was abandonment fears, though for the adults all symptoms were approximately equivalent in this regard. The most efficient exclusion criterion was uncontrolled anger for the adolescents and impulsiveness for the adults. CONCLUSIONS: In hospitalized patients, borderline personality disorder and its symptoms appear to be as frequent for adolescents as for adults. Despite these surface similarities between groups with respect to symptom patterns, several differences were found at the level of the diagnostic efficiency for individual borderline personality disorder criteria. These differences may shed light on the nature of borderline psychopathology during adolescence.     

Treatment utilization by patients with personality disorders

OBJECTIVE: Utilization of mental health treatment was compared in patients with personality disorders and patients with major depressive disorder without personality disorder. METHOD: Semistructured interviews were used to assess diagnosis and treatment history of 664 patients in four representative personality disorder groups-schizotypal, borderline, avoidant, and obsessive-compulsive-and in a comparison group of patients with major depressive disorder. RESULTS: Patients with personality disorders had more extensive histories of psychiatric outpatient, inpatient, and psychopharmacologic treatment than patients with major depressive disorder. Compared to the depression group, patients with borderline personality disorder were significantly more likely to have received every type of psychosocial treatment except self-help groups, and patients with obsessive-compulsive personality disorder reported greater utilization of individual psychotherapy. Patients with borderline personality disorder were also more likely to have used antianxiety, antidepressant, and mood stabilizer medications, and those with borderline or schizotypal personality disorder had a greater likelihood of having received antipsychotic medications. Patients with borderline personality disorder had received greater amounts of treatment, except for family/couples therapy and self-help, than the depressed patients and patients with other personality disorders. CONCLUSIONS: These results underscore the importance of considering personality disorders in diagnosis and treatment of psychiatric patients. Borderline and schizotypal personality disorder are associated with extensive use of mental health resources, and other, less severe personality disorders may not be addressed sufficiently in treatment planning. More work is needed to determine whether patients with personality disorders are receiving adequate and appropriate mental health treatments.     

Integration and sealing over. Clinically distinct recovery styles from schizophrenia.

Concepts of integration and sealing over are common clinical psychiatric parlance. Our experience studying and treating acute schizophrenic patients, primarily with psychosocial techniques, has emphasized the meaningfulness of these concepts. By studying the recovered patient's attitude toward his psychotic experiences, we have obtained material from which to formulate definitions and these concepts. Integrators tend to be curious about their symptoms, regard them as part of their life's pattern, and gain information from them, resulting in a more flexible and variable attitude toward illness than patients who seal over. The latter have rather fixed, usually negative, views of their illness, and tend not to strive to understand their psychotic symptoms nor to place their psychotic experiences in perspective with their lives before and after psychosis.     

Discriminant efficiency of antisocial and borderline personality disorder criteria in Hispanic men with substance use disorders

The authors examined the discriminant efficiency of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition ( DSM-IV ) criteria for borderline personality disorder (BPD) and antisocial personality disorder (APD). Subjects were 74 men admitted to an outpatient substance abuse program for monolingual Hispanic adults. All were reliably assessed with the Spanish-language version of the Diagnostic Interview for DSM-IV Personality Disorders. Conditional probabilities were calculated to determine the diagnostic efficiency and discriminant efficiency of BPD and APD symptoms. Twenty-five (34%) subjects met diagnostic criteria for BPD, and 16 (22%) met criteria for APD. The diagnostic co-occurrence of these disorders was statistically significant. Whereas the diagnostic efficiency of the BPD criterion set was comparable to that reported in other clinical studies, these criteria were not significantly more efficient in diagnosing BPD than APD. By contrast, the APD criteria were more efficient in diagnosing APD than BPD; this was true for both the "adult" and the "conduct disorder" APD criterion subsets. In male Hispanic outpatients with substance use disorders, BPD and APD show significant diagnostic overlap. The APD criteria are useful in discriminating these 2 disorders, whereas the BPD criteria are not. These findings have implications for the discriminant validity of the BPD and APD criteria and support the value of the conduct disorder criteria in predicting APD in adulthood.     

Professionals complementary to dentistry: the expanding role of PCDs

The role of Professionals Complementary to Dentistry is increasing in importance as new ways of exploring dental service provision are considered. Skill-mix and team-building are not just buzzwords, but signify the new view of a multidisciplinary approach in healthcare. Since the Nuffield and DARG reports of the last decade urged consideration of manpower issues within dentistry, the ensuing change from often small, single-handed practice, to larger team approaches has resulted in significant changes in service delivery. It is unsurprising that the bewildered practitioner can become lost in the mire of proposed new regulations. Outlining the current developments in the expanding role of PCDs, this paper illustrates the dynamic nature of the changes.     

Factorial structure of the Scale of Prodromal Symptoms

Data from the Scale of Prodromal Symptoms (SOPS) [Early Intervention in Psychotic Disorders, pp. 135-150] on 94 hitherto never-psychotic individuals were entered into a principal components analysis, revealing six components with an eigenvalue greater than 1.0. Based upon scree-plot analysis, further extractions were limited to three, then two, factors. Varimax rotation of the three-component extraction revealed factors with reasonable congruence with a priori content areas. All symptoms labeled as negative in the SOPS loaded on one factor, and four of five symptoms labeled as positive loaded on another. The remaining positive symptom, conceptual disorganization, has been found not to load with other positive-labeled symptoms in studies of schizophrenia using applicable instruments. All symptoms labeled as "general" in the SOPS loaded on a third factor, which appears to reflect the nonspecific psychological distress that might be expected in psychosis-na?ve individuals experiencing the preliminary stages of a serious psychiatric disorder. The independence of this component from the positive and negative symptom factors suggests that the structure obtained suggests a clinical continuity between the at-risk presentations seen in this sample and established schizophrenia.
