  • Objective:The purpose of this study was to know about the mechanism of pathogenesis of type 2 diabetes mellitus by using of blood glucose, glucoregulatory factor, insulin resistance in schizophrenic patients receiving antipsychotics. Method:Modified oral glucose tolerance tests were performed in 20 schizophrenic patients receiving haloperidol, risperidone and olanzapine. Insulin, glucagon, C-peptide and cortisol were measured in 0, 15, 45, 75 minutes after glucose loading, and insulin resistance was calculated by HOMA(homeostasis model assessment) method. Result:Olanzapine-treated patients had significant glucose elevation 45 minutes after glucose challenge. Also modest increases in HOMA IR values were detected in patients treated with olanzapine. Conclusion:Olanzapine treatment of non-diabetic patients with schizophrenia can be associated with type 2 diabetes mellitus through the elevation of glucose and insulin resistance. Elevated insulin resistance may be a causative mechanism of type 2 diabetes mellitus in patients receiving olanzapine.

  • Objectives : This study was conducted in order to describe prescribing practices in treatment of pediatric bipolar disorder in a Korean inpatient sample. Methods : We performed a retrospective chart review of 66 youths who had been hospitalized and diagnosed with bipolar disorder according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria. Demographics, clinical characteristics, medications used, doses, and related adverse events were examined. Results : Mood stabilizers and/or atypical antipsychotic medications were the primary treatment. Risperidone, valproate, and lithium were the most commonly used. Thirty seven patients (58.1%) were treated with combination therapy of an atypical antipsychotic and mood stabilizer for improvement of manic/mixed symptoms. Conclusion : Combination pharmacotherapy was necessary for most patients in this admission sample group. Conduct of further studies will be needed for evaluation of treatment response according to the clinical characteristics, and the safety and efficacy of treatment for child and adolescent bipolar disorder.

  • The objective of this review is to establish practice parameters for pharmacological treatment of children and adolescents with pervasive developmental disorders. We performed a detailed review of the literature, including a wide range of controlled clinical trials, open trials, case reports, and side-effect profiles of related drugs. Few medications have a treatment indication for pervasive developmental disorders, and few studies with well-controlled methodology are available for evaluating treatment results. Pharmacological treatments focus on associated target symptoms because symptom reduction may improve educational and social ability and enhance quality of life. Well-controlled trials have been conducted for some SSRI(selective serotonin reuptake inhibitor) antidepressants, risperidone, and methylphenidate, and showed reduction of some target symptoms. Since the medications are not specific to autism and do not treat core symptoms of the disorder, their potential side effects should be carefully considered. Family education is necessary to give proper information on target symptoms, limitation of drug treatments, and risks.

  • The autistic disorder is identified as an independent clinical entity, since the first description of Leo Kanner. The etiologies of the autistic disorder are almost unclear and the autistic disorder has several abnormalities in aspect of morphology and function of brain. Self-mutilation is observed in the low functioning autistic patients, and early treatment for self mutilation are needed in order not to be chronic. This article reviewed the drugs for the several symptoms of the autistic disorder, especially for self-mutilation. The serotonin reuptake inhibitors does not have clear primary anti-aggressive effects. The dopamine blockers have considerable effects in order to decrease aggression and self injury, and the risperidone is most recommended because of side effects of conventional drugs. The naltrextone does not have consistent study results yet. The clonidine has aggression-decreasing effect. Also lithium is effective on the treatment for aggressive and self-injurious behaviors. And the anticonvulsants including carbamazepine are effective on aggressive explosive behaviors. In the future the pharmacotherapy for self-mutilation will be advanced through stalbe diagnosis and measurement of treatment response.

  • Objectives : Antipsychotic-induced hyperprolactinemia causes physical symptoms, such as amenorrhea, galactorrhea, gynecomastia, sexual dysfunction, and bone density loss, as well as psychiatric symptoms, such as depression and cognitive impairments. This study aimed to clarify the associations among hyperprolactinemia caused by antipsychotics in patients with schizophrenia, psychiatric pathology, and psychosocial factors. Methods : Ninety-nine patients with schizophrenia in the psychiatry department of a university hospital were registered between 2015 and 2017. All participants were assessed using structured questionnaires to elucidate psychopathology, social function, quality of life, and hyperprolactinemia-related side effects. The standard levels for hyperprolactinemia were 24ng/mL for women and 20ng/mL for men. Results : The average prolactin levels were $73.45{\pm}49.37ng/mL$ in patients with hyperprolactinemia and $9.16{\pm}6.42ng/mL$ in those without hyperprolactinemia. The average prolactin level in women was significantly higher than that in men(p=0.04). Risperidone was most commonly administered in patients with hyperprolactinemia(58.1%, p<0.01), while aripiprazole was most commonly administered in those without hyperprolactinemia(44.7%, p<0.01). Patients with hyperprolactinemia had significantly higher Positive and Negative Syndrome Scale(p=0.03) and Patient Health Questionnaire-9(p=0.05) scores and had significantly lower Social and Occupational Functioning Assessment Scale(p=0.04) and Strauss-Carpenter Levels of Functioning Scale(p=0.03) scores than patients without hyperprolactinemia. There were no significant differences in side effects or quality of life between the two groups. Conclusion : These findings demonstrate that hyperprolactinemia confers negative effects on depression and social function, but does not directly affect the quality of life. These results suggest that patients with schizophrenia who take antipsychotics that increase prolactin or cause side effects of hyperprolactinemia need to be assessed and receive interventions for depression.

  • Objectives : The purpose of this study was to investigate clinical characteristics of children and adolescents with autism spectrum disorders (ASDs) using methylphenidate (MPH). Methods : Retrospective review of the charts of 79 children and adolescents with ASDs, who visited the Department of Child and Adolescent Psychiatry of Seoul National Hospital, from July 2010 to July 2011, was conducted. Changes in illness severity and improvement were measured using the Clinical Global Impression-Severity of illness (CGI-S) and Clinical Global Impression-Improvement (CGI-I) Scales. Results : We found that MPH was prescribed in 23 (29.1%) children and adolescents. Of the 23 patients on MPH, 4 patients (17.4%) were on MPH monotherapy and 18 patients (78.3%) were using risperidone concomitantly. MPH was prescribed primarily for symptoms of hyperactivity and impulsivity in ASDs patients. The mean dosage of MPH was $26.2{\pm}11.1$mg/day and mean duration of treatment was $31.9{\pm}28.7$ months. Mean CGI-S score improved significantly from baseline to endpoint (from $5.4{\pm}0.6$ to $4.1{\pm}0.9$ ; p<.01). MPH was reported to be effective in 17 patients (17/23, 73.9%), and 10 patients (10/23, 43.5%) reported side effects. Side effects included decreased appetite (4/23, 17.4%), tic (2/23, 8.6%), sleep disturbances (2/23, 8.6%), headache (1/23, 4.3%) and irritability (1/23, 4.3%). Conclusion : The results of this study demonstrate that MPH may be used effectively and safely in children and adolescents with ASDs with hyperactivity and impulsivity. Future controlled trials are needed to confirm these findings.

  • Objectives Second-generation antipsychotics (SGAs) are frequently used in the treatment of bipolar disorder. However, there is still no consensus on their risk of tardive movement syndromes especially for first-generation antipsychotics (FGAs)-naïve patients. This study aimed to investigate the prevalence and associated factors of SGAs-related tardive dyskinesia and tardive dystonia in patients with bipolar disorder, in a naturalistic out-patient clinical setting. Methods The authors assessed 78 non-elderly patients with bipolar (n = 71) or schizoaffective disorder (n = 7) who received SGAs with a combined use of mood stabilizers for more than three months without previous exposure to FGAs. Multiple direct assessments were performed and hospital records longer than one recent year describing any observed tardive movement symptoms were also reviewed. Results The prevalence rates of tardive dyskinesia and tardive dystonia were 7.7% and 6.4%, respectively. These patients were being treated with ziprasidone, risperidone, olanzapine, quetiapine, or paliperidone at the time of the onset of the movement symptoms. Tardive dyskinesia was mostly observed in the orolingual area, and tardive dystonia was most frequently detected in oromandibular area. A past history of acute dystonia was significantly associated with presence of both tardive movement syndromes. Conclusions Our findings suggest that SGAs-related tardive movement syndromes occur in a substantial portion of bipolar disorder patients. Acute dystonia, a reported risk factor of tardive movement syndromes in the era of FGAs is confirmed as a risk factor of both tardive dyskinesia and tardive dystonia that were induced-by SGAs.
