Lamotrigine-induced tic disorder: report of five pediatric cases

PURPOSE: To describe the clinical spectrum of lamotrigine (LTG)-induced tics (an uncommon side effect) in children. METHODS: Retrospective analysis of patients from our hospital-based practice who developed tics while on LTG. Data obtained from medical records, interviews with parents, video-EEGs, and homemade videotapes. RESULTS: Three males and two females (range, 2.5-12 years; mean, 6.9 years) developed a movement disorder within the first 10 months of therapy (maintenance doses, 4-17 mg/kg/day). Four patients exhibited simple motor tics; one patient experienced mostly vocal (i.e., gasping sounds) tics. Laryngoscopic evaluation of one 2.5-year-old with repetitive gasping sounds was normal. In three cases, tics resolved completely within 1 month of drug cessation; tics recurred in two of these patients after reintroduction of LTG. A fourth patient experienced gradual improvement after stopping LTG over 4 months; the fifth patient's simple motor tics improved spontaneously with a reduction in medication. None of the patients had clinical features of a neurodegenerative disorder, and none met diagnostic criteria for Tourette syndrome. Two patients, however, had a diagnosis of acquired epileptic aphasia syndrome, and one patient had nonprogressive expressive and receptive language dysfunction. A fourth patient had global static encephalopathy, and the fifth patient had only attentional problems. In all patients, tics were not associated with ictal EEG changes. CONCLUSIONS: LTG may infrequently induce simple motor tics, vocal tics, or both. Patients with severe language dysfunction may be particularly susceptible to this uncommon side effect. Further studies are necessary to clarify the population at risk.     

Behavioural inhibition: A predictor of anxiety

Anxiety disorders are prevalent and contribute to emotional suffering and significant economic loss. Early identification and treatment are essential, not only to reduce the associated morbidity, disability and mortality of the anxiety disorders themselves, but also to minimize development of frequent comorbidities such as depression and substance abuse. To understand the factors that increase susceptibility to developing anxiety disorders, a temperamental construct called behavioural inhibition, which refers to the consistent tendency of some children to demonstrate fear and withdrawal in novel situations, has been developed. The present article reviews studies investigating this model as a premorbid predictor of those at risk for developing anxiety disorders, including prospective studies of children at risk as well as retrospective and family studies. In summary, these data suggest the usefulness of this model and a need for further research to determine the optimal management of behaviourally inhibited children as a potential way to prevent adult psychopathology.     

差异教学的探讨与实践

有研究者对中小学生的IQ分数与学习成绩分数进行过大量的相关调查，结果发现两者的相关系数大致为0.5，两者只为中等相关程度。也就是说，影响学习的因素应是多方面的。而布卢姆研究认为，学生学习成绩的差异主要由三个方面的因素造成，即是认知前提行为、情感前提特性、教学质量。本文试图以布卢姆的研究结果为依据，结合自己的教学实践，从多个方位探讨应对差异、实现面向全体的教学策略。     

Understanding Atypical Emotions Among Children with Autism

Children with autism are said to be poor mind readers: They have a limited understanding of the role that mental states play in determining emotions and behavior. In this research, 23 high-functioning children from the autistic spectrum (M age 9 years 3 months), 42 6-year-old controls, and 43 10-year-old controls were presented with six emotion-evoking stories and they were asked to explain protagonists' typical and atypical emotions. In the case of typical emotions, as expected on the basis of the mindblind hypothesis, children from the autistic spectrum gave few mental state explanations, referring to fewer than even the 6-year-old control group. However, in the case of atypical emotions, the autistic group performed as well as the 10-year-old controls. Their explanations for the atypical emotions demonstrate that children from the autistic spectrum indeed have the capacity to mind read (with respect to both desires and beliefs), although they do not always use this capacity in the same way as normally developing children. It is argued that the mind-reading capacity of high-functioning children from the autistic spectrum might be basically intact; unused in everyday circumstances but not necessarily defective.     

Symptom dimensions in recent-onset schizophrenia and mania: a principal components analysis of the 24-item Brief Psychiatric Rating Scale

Previous four- and five-factor solutions of the 18-item Brief Psychiatric Rating Scale (BPRS) suggested the possibility of an affective dimension in psychosis. A principal components analysis was used to analyze psychiatric symptom data rated on an expanded 24-item version of the BPRS. BPRS data were collected during a period of acute psychotic and affective illness with 114 young adult, recent-onset schizophrenia and schizoaffective patients and 27 bipolar manic patients. Principal components analyses of the 18-item and 24-item BPRS indicated a four-factor solution was the most interpretable. Principal components analysis of the 24-item BPRS produced a clear mania factor characterized by high loadings from items added to the 18-item BPRS, which included elevated mood, motor hyperactivity, and distractibility. This factor solution suggests that the 24-item BPRS allows for an expanded assessment of affective symptoms relating to a manic dimension. Potentially important symptoms that were added to the traditional 18-item version, namely suicidality, bizarre behavior, and self-neglect, also make clear contributions to other factors.     

Use of brief psychiatric screening measures in a primary care sample

Patients seen in primary medical clinics report higher rates of major depression [Pérez-Stable et al., 1990: Arch Intern Med 15:1083-1088], and panic disorder [Sherbourne et al., 1996b: Von Korff et al., 1987: Arch Gen Psychiatry 44:152-156] than the general population. Primary care staff therefore need efficient methods of identifying patients with psychiatric disorders. The current study evaluates the use of several brief psychiatric screening measures for identifying patients with major depression and/or anxiety disorders. Participants were 213 primary care patients who received the Center for Epidemiological Studies Depression Scale (CES-D), the Beck Anxiety Inventory (BAI), and two new instruments, the Autonomic Nervous System Questionnaire (ANS) for assessing panic disorder and the Social Phobia Questionnaire (SPQ) for assessing social phobia. Participants received both the screening instruments and a structured diagnostic interview. Results suggest that the CES-D is a useful measure for detecting psychopathology, but it is not particularly specific to depression, the ANS was a highly sensitive and reasonably specific measure for panic disorder, and the SPQ was reasonably sensitive and specific for social phobia. The BAI was a relatively poor screening measure that added no significant information beyond the other measures.     

Recovery from a recurrent major depressive episode

Episode-related factors and antidepressant treatment adequacy may be important determinants of recovery from a major depressive episode (MDE). We compared recovered and nonrecovered patients on baseline sociodemographic, clinical and episode-related measurements. Twenty-five inpatients with recurrent major depressive disorder diagnosed by SADS-L participated in this naturalistic, prospective, longitudinal study. Recovery, which was defined as a sustained return to non-depressed status lasting > or = 8 consecutive weeks, was assessed at 6- and 12-month follow-up with the Streamlined Longitudinal Interval Continuation Evaluation (SLICE). Thirteen (52%) patients met recovery criteria. The cumulative proportion remaining depressed for at least 52 weeks was 42.5%. Recovered patients had shorter episodes preceding the index hospitalization (P = .01). Despite adequate antidepressant pharmacotherapy, the length of the current episode remains the most important correlate of recovery from MDE recurrence. Our small sample size and the uncontrolled nature of treatment may limit the generalizability of these findings.     

Typus melancholicus and the Temperament and Character Inventory personality dimensions in patients with major depression

Although many clinical studies have been conducted to determine the etiological role and clinical implications of typus melancholicus for unipolar depression, maladaptive personality features in depressive patients have not been well described. This study explores typus melancholicus, as measured by the rigidity subscale of the Munich Personality Test, and maladaptive personality features, as measured by the Temperament and Character Inventory (TCI), in 131 remitted patients with DSM-IV major depression and 154 normal controls. The patients reported significantly higher scores on rigidity and harm avoidance and significantly lower scores on self-directedness and cooperativeness. Only 23.6% of the variance of the rigidity scale was explained by the variance of the seven TCI scales, in which only persistence was significantly correlated positively to rigidity. Cluster analysis identified four subgroups, two of which were characterized by a high rigidity score. One of these two subgroups showed no maladaptive personality features, as measured by the TCI, while the other showed high harm avoidance and low self-directedness. These results indicate that the personality of depressive patients is characterized not only by typus melancholicus but also by maladaptive personality features, that typus melancholicus is not well represented by any TCI scale, and that typus melancholicus and maladaptive personality features can coexist in some depressive patients.     

Abnormal illness behavior and psychiatric disorders: a study in an outpatient clinic in Japan

Abnormal illness behavior, such as hypochondriacal attitude and inappropriate treatment-seeking, has been associated with various psychiatric disorders in which patients tend to abuse medical services and seek inappropriate treatment in general practice clinics rather than psychiatric clinics. However, the relationship between illness behavior and psychiatric disorders in Japan is yet to be elucidated. We examined the abnormal illness behavior of 243 patients who visited the outpatient department of psychiatry at Saga Medical School Hospital, Saga, Japan, using a Japanese version of the Illness Behavior Questionnaire (IBQ). Multivariate analysis indicated significant association between some of the IBQ scale scores and age, sex and employment status. Patients with anxiety disorder scored higher on five of the seven IBQ scales compared with patients with another major disorder (mood disorder, schizophrenia or somatoform disorder). When compared with the IBQ scale scores reported in Australian patients in a psychiatric hospital, most of the IBQ scale scores differed significantly in our patients; a higher score among Japanese patients on the general hypochondriasis scale was most prominent. A similar trend in IBQ scale scores was also noted among Japanese patients visiting the hospital's general medicine clinic in comparison with Australian patients visiting a general practice clinic. Japanese patients with anxiety disorder may display the most salient abnormal illness behaviors among patients with psychiatric disorders. Sociocultural background may contribute to the characteristic abnormal illness behaviors of Japanese patients.
