OBJECTIVES: In previous researches the measure of quality of life was assessed either by the subjective experience only or by the objective assessment only, but there have been few studies done using both of these measures and the relationship between these two sides. The aim of this study is to examine the relationship between the subjective experience and the objective assessment of the quality of life in schizophrenic patients and to find out whether the self-rating of these patients is reliable. Also, the relationship between the assessment of the quality of life and the psychopathology of schizophrenia was investigated. METHODS: The subjects are 48 out-patients, from either Yongdong Severance Hospital or Seoul Paik Hospital, whose diagnosis were schizophrenia according to DSM-IV. The standardized Korea version of Quality of Life Scale(K-QOLS) was used for evaluating the objective assessment of quality of life, while both the Korean modification of the Scale to Measure Subjective Well-being under Neuroleptic treatment(KmSWN, 2000) and the Satisfaction of Life Scale(SOL) was used in the evaluation of subjective experience of satisfaction of life. The psychopathology of each patient was assessed by the Positive and Negative Syndrome Scale(PANSS). The patient underwent all the scales on the same day, and the relationship between each scale were analysed by the Spearman's correlation coefficient. RESULTS: The results came out that the total score of PANSS showed negative correlations with the total score of K-QOLS, especially the negative subscale score and the general psychopathology subscale score was correlated more significantly. The total score of KmSWN showed no correlations with neither the total score nor the positive/negative subscale score of PANSS, but the general psychopathology subscale score showed negative correlations with KmSWN significantly. The score of K-QOLS, reflecting the objective assessment, and the score of KmSWN, reflecting the subjective experience, showed positive correlations with each other. But the total score of SOL, reflecting the subjective experience also, showed no correlations with K-QOLS. The score of KmSWN showed positive correlations with the subdomains of interpersonal relations and intrapsychic foundation of K-QOLS, but did not correlate with occuaptional role and daily acitivities. Especially the emotional regulation, the subdomain of KmSWN showed positive correlations with the subscales of K-QOLS. And the subjective and objective quality of life scale both showed negative correlations with the duration of illness and dosages of drugs. CONCLUSIONS: These results suggested that the more severe the psychopathology, the lower the objective quality of life in out-patients with schizophrenia, and the more severe the general psychopathology, the lower the subjective quality of life. The positive relationships between the subjective measure and the objective measure in quality of life were also proved, suggesting that the self-rating of these patients is reliable. The longer the duration of illness and the higher the dosages of drugs, the lower the quality of life in patients with schizophrenia.

OBJECTIVE: Obsessive-compulsive disorder (OCD) is a clinically heterogeneous disorder with a bimodal pattern in age onset and treatment outcomes. This study attempted to ascertain the importance of the age factor for a better phenotypic precision. Therefore, the authors compared adult OCD patients with an early symptom onset to adult OCD patients with a later symptom onset. METHODS: One hundred sixty five patients with OCD were evaluated with semistructured interviews;79 with symptom onset before the age of 17 (early onset group) and 86 with symptom onset after the age of 17 (late onset group). The two groups were analyzed in terms of Y-BOCS (Yale-Brown Obsessive Compulsive Scale) scores and demographic data including clinical variables. RESULTS: Early onset group has more comorbidity of tic disorder and lesser of depression and anxiety disorder than late onset group. Early onset group showed more family history of tic disorder than late onset group. The treatment response to SSRI is relatively declined after 18 months of initiation in early onset group. CONCLUSION: The results indicate that age at onset may be an important factor in subtyping OCD. Early onset group may have more biological and familial tendency that might be differentiate the two groups.

OBJECTIVE: Dopamine transporter is a key regulator of dopamine neurotransmission and is also the primary target of methylphenidate. This study tested the hypothesis that dopamine transporter (DAT) density in basal ganglia is a predictor of favorable methylphenidate (MP) treatment response. METHODS: 15 drug-naive boys with ADHD were included in this study (8 children: treatment responder, 7 children: treatment non responder). They were assessed with psychiatric interview, KEDI-WISC, K-ARS, ADS and CBCL. After then, they were performed [123 I]IPT SPECT. They were evaluated about treatment response after treatment with methylphenidate during 8 weeks. SPECT data reconstructed for the assessment of specific/nonspecific DAT binding ratio of the basal ganglia were compared between treatment responders and nonresponders. RESULTS: There were not significant differences in dopamine transporter density in basal ganglia between the two groups. CONCLUSION: This finding suggests that dopamine transporter density does not mediate the MP treatment response in a direct way.

OBJECTIVES: Suicide is one of the most common causes of deaths in correctional institutions. This study aimed to examine the characteristics of suicide attempts and its related psycho-social factors in correctional institutions. METHODS: This study examined the characteristics of 101 suicide attempts from 2006 to 2007 in the two regional correctional headquarters. Thirty-seven male inmates (43 suicide attempts) and 40 matched controls were included in interviews and reviews of personal records. Psychiatric illnesses were examined using the Structured Clinical Interview for DSM-IV and medical outcomes of their suicide attempts with the Lethality Scale of Diagnostic Interview for Genetic Studies. RESULTS: Over a half of suicide attempts occurred in solitary cells and the most common method was hanging. Medically, 70% of the suicide attempts were more than severe. Poor social support, a lifetime history of suicide attempts, and incarceration were associated with suicide attempts. Additionally, psychiatric illnesses were more likely to increase the risk of suicide. CONCLUSION: This study implies that mental health issues and monitoring systems are important to reduce suicides in the correctional system. Regular checks and management of suicide risk and mental illness are crucial to prevent suicide in correctional institutions.

OBJECTIVE: The definite causes of obsessive-compulsive disorder (OCD) are still unknown. Evidences from familial, twin and segregation studies support the role of a genetic component in the etiology of OCD. There are growing evidences that OCD has specific neurochemical and neuroanatomical basis. It has been shown that serotonergic neurons play the predominant pathophysiological role in OCD. Recently, it has also been proposed that neurotransmitters other than serotonin play a role in the pathophysiology of OCD, and a series of studies have provided evidence that dopamine is involved in some OCD patients. Therefore, the aims of this study were to investigate the association between dopamine receptor D4 (DRD4) and OCD. METHODS: One hundred and fifteen OCD patients and 160 normal controls participated in this study. Genomic DNA was extracted from their blood. The genotypes and allele frequencies of the DRD4 polymorphism between OCD group and control group were compared. OCD patients were classified into early onset group (age of onset <17) and late onset group (age of onset > or =17) according to their onset age and the genotype and allele frequency were compared between two groups. Using principal component analysis, we had already derived 4 factors from 13 main contents of YBOCS checklist in the previous study and in this study, we investigated the association between these three factors and DRD4 genotypes. RESULTS: In this case-control study, we could find that the L-genotype frequencies of DRD4 were significantly higher in OCD than in normal control groups (chi2 test, p=0.04). There were no difference in genotype frequencies between early onset OCD group and late onset OCD group. In OCD group, patients with L-genotype had higher scores for the religious/somatic factor than the other groups (t test, p=0.009). CONCLUSIONS: The L-genotype of DRD4 may have negative effects on the development of OCD and religious/somatic factor of the obsessive-compulsive symptoms.

BACKGROUND: Postoperative morbidity and mortality in destroyed lung are relatively high. We tried to identify the prognostic factors affecting postoperative morbidity and mortality in destroyed lung through a retrospective study. MATERIAL AND METHOD: The retrospective study was undertaken in 112 patients who had undergone pneumonectomy or pleuropneumonectomy for destroyed lung at Severance Hospital from 1970 to 2000. We analyzed the correlation between postoperative morbidity and mortality and etiology, duration of disease, preoperative FEV1, presence or absence of preoperative empyema, operation timing, the side of operation, duration of operation, and operation type. RESULT: There were 55 men and 57 women, aged 20 to 81 years (mean 44 years). Etiologic diseases were tuberculosis in 86 patients(76.8%) including tuberculous empyema in 20 and tuberculous bronchiectasis in 4, pyogenic empyema in 12(10.7%), bronchiectasis in 12(10.7%), and lung abscess in 2(1.8%). Postoperative morbidity were 25%(n=28) and postoperative mortality was 6%(n=7). The presence of preoperative of empyema(p=0.016), pleuropneumonectomy(p=0.037) and preoperative FEV1 of less than 1.75 L(P=0.048) significantly increased the postoperative morbidity. If operation time was less than 300min, postoperative morbidity(p=0.002) and mortality(p=0.03) were significantly low. CONCLUSION: Postoperative morbidity and mortality in destroyed lung were acceptable. Postoperative morbidity and mortality were significantly low when operation time was less than 300 min. Preoperative existence of empyema, pleuropneumonectomy and preoperative FEV1 of less than 1.75 L significantly increased postoperative morbidity.

OBJECTIVE: This investigation was performed to uncover the nature of the clinical drug trials in the past in Korean psychiatry and to prepare some guidelines for the good clinical practice in the future. METHOD: We reviewed total 212 papers of the clinical drug trials in the major Korean psychiatric journals from April 1962 to December 1998. RESULTS: From the year 1985, when the pharmacological and biological organizations in psychiatry were found in our country, the clinical drug trials are rapidly expanding. Although open clinical trials in small sample size less than 30 subjects were the most frequent in the past, some well-designed clinical trials such as multicenter double-blind cross-over study were performed recently. Majority of these 212 clinical trials was done in patients with schizophrenia and mood disorders. Haloperidol was just the drug most frequently evaluated in the clinical trials in our country. As expected, among several clinical rating scales, Brief Psychiatric Rating Scale was the most frequently used. Prolactin and homovanillic acid were the materials frequently measured in the patients with schizophrenia. A few of these clinical trials were performed under the financial supports from the industry, and only one biological research had gained a fund from a national academic institute. To evaluate the researchers' concepts for the medical ethics in the clinical drug trials, we reviewed the description about the informed consent and the approval of institutional review board in all papers. Surprisingly, we found no descriptions about the informed consent in 113 papers(65.8%). Only one clinical trial was performed after the approval of the institutional review board. CONCLUSIONS: We confirmed that the majority of the clinical psychiatric drug trials in the past were performed in lacks of the concept of Good Clinical Practice(GCP). The KGCP guideline did not influenced on the researchers' concepts and performance for the medical ethics at all. Although all of the clinical trials may not need to be done under the guidelines of GCP, clinical researchers' efforts for the medical ethics should be continued for both, the patient and the researcher.
