Posttraumatic Stress Disorder Among Occupational Accident Patients / 신경정신의학

OBJECTIVES: This study was conducted to assess the development of posttraumatic stress disorder (PTSD) after occupational physical injuries and the risk factors in occupational accident patients for PTSD. METHODS: Forty-seven occupational accident patients with physical injuries were administered BDI, STAI I and II, SCL-90-R, IES and questionnaires for risk factors and Clinician-Administered PTSD Scale(CAPS). RESULTS: 1) 12 patients(25%) were diagnosed as PTSD. 2) The BDI, STAI I and II and IES scores are significantly high(<0.05) in PTSD group than non-PTSD group. 3) The subscales of SCL-90-R, with an exception of PAR subscale, showed higher scores(<0.05) in PTSD group. 4) The loss of consciousness(LOC) was only significant risk factor in the occupational accident-related factors(<0.05). CONCLUSION: The results of this study show the development of PTSD among occupational accident patients. The loss of consciousness(LOC) was the only signiticant risk factor for PTSD in occupational accident patients.

Apolipoprotein E Polymorphism in Schizophrenic Patients / 신경정신의학

OBJECTIVES: To explore the role of apolipoprotein E in schizophrenia, we investigated apoli-poprotein E polymorphism in groups of patients with schizophrenia and normal controls. We also examined the relationship of clinical characteristics of schizophrenia to apolipoprotein E genotypes. METHODS: Samples were obtained from 101 schizophrenic patients and 96 controls in Korea and apolipoprotein E polymorphisms were analysed using polymerase chain reaction. RESULTS: The genotype and allele frequencies did not differ from those of controls. The clinical variables of schizophrenia, such as positive and negative groups by PANSS, subtypes by DSM-IV, family history were not associated with each genotypes. CONCLUSION: We could not find the association of apolipoprotein E in Korean schizophrenic patients and it could be suggested that apolipoprotein E isoforms might not play a main role in expression of schizophrenia.

Weight Gain Associated with Atypical Antipsychotic Drugs / 대한정신약물학회지

The purpose of this study is to compare weight gain by risperidone, clozapine and olanzapine which are atypical antipsychotic drugs with that by haloperidol which is typical antipsychotic drug. METHODS: We performed a retrospective chart review of 278 schizophrenic patients who were treated longer than 12 weeks with 4 different drugs. We measure weight gain weekly until 12th week and weight change curve over 12 weeks was drawn. Additionally, we examined any correlations of weight change with some factors. RESULTS: 1) The highest weight gains were observed in the olanzapine and clozapine groups, followed by the risperidone and haloperidol groups. 2) The haloperidol group showed a main weight gain within first 3 weeks, and patients ingested 3 atypical drugs gained weight steadily during 12 weeks. 3) The initial underweight group showed the largest weight gain. CONCLUSION: This study shows that the atypical antipsychotic drugs induced more weight gain than haloperidol. And we can expect that long-term treatment with clozapine and olanzapine would induce more severe weight gain, particularly in underweight patients.
