Psychiatric Symptoms Among Female Adult Victims of Sexual Molestation : Comparison with Rape Victims / 정신신체의학

OBJECTIVES: According to the recent Korean National Police Agency report, rape victims were 17.1%, but sexual molestation victims were more than the rape victims by 78.0%. Despite many international reports about the occurrence of severe psychiatric symptoms in sexual molestation victims, there is no domestic research. Therefore in this study, we investigated psychiatric symptoms of sexual molestation victims, and we also compared it with psychiatric symptoms in rape victims. METHODS: 58 women who visited Busan Smile Center within 3months after sexual violence were the study subjects. Questionnaire about sociodemographic and sexual violence related characteristics were retrospectively investigated. Of the psychiatric symptoms, Beck Depression Inventory(BDI), Beck Anxiety Inventory(BAI) for severity of depression and anxiety, and Impact of Event Scale-Revised(IES-R) to check the presence of posttraumatic stress disorder(PTSD) symptoms were used. RESULTS: Of 58 sexual violence victims, sexual molestation victims were 36(62.1%) and rape victims were 22(37.9%). In sexual molestation victims, 80.6% had more than moderate severity of depression, 83.3% had more than moderate severity of anxiety, and 94.4% had significant scores at PTSD screening test. Compared with rape victims' psychiatric symptoms(each 95.5%, 95.5%, 95.5%) there were no significant difference. CONCLUSIONS: The majority of sexual molestation victims were also accompanied by depression, anxiety and PTSD symptoms as rape victims. There results suggest that appropriate assessment and early treatment for psychiatric symptom must be made in the early stage of injury in sexual molestation victims.

Times to Discontinue Antidepressants Over 6 Months in Patients with Major Depressive Disorder

OBJECTIVE: The aim of the present study was to investigate differences in discontinuation time among antidepressants and total antidepressant discontinuation rate of patients with depression over a 6 month period in a naturalistic treatment setting. METHODS: We reviewed the medical records of 900 patients with major depressive disorder who were initially prescribed only one kind of antidepressant. The prescribed antidepressants and the reasons for discontinuation were surveyed at baseline and every 4 weeks during the 24 week study. We investigated the discontinuation rate and the mean time to discontinuation among six antidepressants groups. RESULTS: Mean and median overall discontinuation times were 13.8 and 12 weeks, respectively. Sertraline and escitalopram had longer discontinuation times than that of fluoxetine, and patients who used sertraline discontinued use significantly later than those taking mirtazapine. No differences in discontinuation rate were observed after 24 weeks among these antidepressants. About 73% of patients discontinued antidepressant treatment after 24 weeks. CONCLUSION: Sertraline and escitalopram tended to have longer mean times to discontinuation, although no difference in discontinuation rate was detected between antidepressants after 24 weeks. About three-quarters of patients discontinued antidepressant maintenance therapy after 24 weeks.

Comparative Study of Adolescents' Mental Health between Multicultural Family and Monocultural Family in Korea

OBJECTIVES: With the observation of factors influencing depression, self-reported happiness, self-reported stress and suicidal attempt, this study compared and evaluated the mental health of adolescents from multicultural families and monocultural families in Korea. METHODS: This study compared the characteristics of adolescents from multicultural and monocultural families based on the analysis of data of The Tenth Korea Youth Risk Behavior Web-based Survey and analyzed the factors influencing adolescent depression, self-reported happiness, self-reported stress and suicidal attempt. RESULTS: There was no significant difference in the levels of depression, self-reported happiness, and self-reported stress between adolescents from multicultural and monocultural families. However, suicidal ideation and suicidal attempt were significantly higher in adolescents from multicultural families. CONCLUSION: There was no significant difference between the mental health of adolescents from multicultural and monocultural families. Because depression is the greatest factor for suicidal attempt, and violence has stronger relationship with depression of adolescents from multicultural families, further study is needed to prevent this trend.

The Relationship between Language Ability and Cognitive Function in Patients with Schizophrenia

OBJECTIVE: Cognitive dysfunction is common in people with schizophrenia, and language disability is one of the most notable cognitive deficits. This study assessed the use and comprehension ability of the Korean language in patients with schizophrenia and the correlations between language ability and cognitive function. METHODS: Eighty-six patients with schizophrenia and a group of 29 healthy controls were recruited. We assessed both clinical symptoms and cognitive functions including Korean language ability. For clinical symptoms, the Positive and Negative Syndrome Scale, Clinical Global Impression-Schizophrenia Scale, and Social and Occupational Functioning Assessment Scale were used. For the Korean language ability assessment, a portion of the Korean Broadcasting System (KBS) Korean Language Test was used. The Short-form of Korean-Wechsler Adult Intelligence Scale, the Korean version of the University of California San Diego (UCSD) Performance-based Skills Assessment (K-UPSA), and the Wisconsin Card Sorting Test (WCST) were used to assess cognitive functions. RESULTS: Schizophrenic patients had significantly lower scores in the language and cognitive function tests both in the total and subscale scores. Various clinical scores had negative correlations with reading comprehension ability of the KBS Korean Language Test. The WCST and a part of the K-UPSA had positive correlations with multiple domains of the language test. CONCLUSION: A significant difference was found between schizophrenic patients and controls in language ability. Correlations between Korean language ability and several clinical symptoms and cognitive functions were demonstrated in patients with schizophrenia. Tests of cognitive function had positive correlations with different aspects of language ability.

The Relationship of Alcohol Withdrawal Delirium and Alcohol Withdrawal Symptoms in Patients with Alcohol Dependence

OBJECTIVE: This study was performed to analyze the clinical variables associated with occurrence of delirium tremens (DT) in inpatients with alcohol dependence initially admitted with diseases unrelated to alcohol. METHODS: This study included 132 inpatients seeking treatment for medical problem with acute alcohol withdrawal. The cases were divided into two groups : with DT group (n=44), without DT group (n=88). We compared the epidemiologic data, alcohol withdrawal symptoms and serum analysis data between two groups. We used the logistic regression to predict risk factors for DT. RESULTS: The DT group had more severe alcohol withdrawal symptoms, more amount of drinking alcohol, more number of drinking per month, higher blood urea nitrogen (BUN), creatinine, amylase, C-reactive protein and lower serum total protein than the without-DT group. According to the result of a logistic regression, occurrence of DT showed correlation with the following factors : sweating, hallucination, agitation, amount of alcohol consumption, number of drinking per month. CONCLUSION: Our study suggests development of DT was correlated with severe alcohol withdrawal symptoms, high BUN, creatinine and low total serum protein. Therefore, during assessment of alcohol dependent patients, clinicians should keep these parameters in mind in order to prevent DT.

A Review of Pharmacological Strategy for Cognitive Deficits in Schizophrenia / 대한정신분열병학회지

Cognitive deficit is frequently observed in patients with schizophrenia. It is significantly associated with functional outcome. In the past 20 years, due to significant advances on the concept of schizophrenia, cognitive deficit has been accepted as a core feature. In the DSM-5, cognitive deficit does not introduce diagnostic criteria of schizophrenia, but did one dimension of diagnosis of psychosis. Existing schizophrenia drugs are effective in treatment of positive symptoms of schizophrenia, but lack of effectiveness on improving cognitive function. Led by NIMH (National Institute of Mental Health), the MATRICS (Measurement and Treatment Research to Improve Cognition in Schizophrenia) meeting was conducted in order to achieve consensus on measuring tools and neuropharmacological targets for clinical trials for development of new drugs for improvement of cognitive function in schizophrenia. At the MATRICS consensus meeting, glutamatergic modulators and nicotinic and muscarinic agonists are expected to be promising, but should be proven by a double-blind placebo-controlled multicenter study for patients.

Electroconvulsive Therapy for Patients with Treatment-Resistant Schizophrenia Patients : A Retrospective Study / 신경정신의학

OBJECTIVES: This study analyzes the effect of electroconvulsive therapy (ECT) by predicting the factors contributing to the effectiveness of ECT and evaluating the persistency of ECT effect in patients with treatment-resistant schizophrenia. METHODS: Using retrospective review of the charts of 24 schizophrenic inpatients who were admitted to Busan Paik Hospital between March 1, 2005 and December 31, 2009. We compared the pre-ECT Clinical Global Impression (CGI) scores and post-ECT CGI scores among these patients. We evaluated the differences in the ECT responses by sex, age, duration of illness and dose of antipsychotic agents, and investigated the rate of continuation of out-patient treatment and readmission, and the change of the CGI score for 12 months after the ECT. RESULTS: ECT resulted in an overall clinical improvement as measured on the CGI scale. 15 (62.50%) patients were good responders, while 9 (37.50%) were poor responders. There was no significant difference between sex, age, duration of the illness, and dose of antipsychotics taken by the patient before the ECT. 21 (87.50%) patients continuously visited the outpatient department for 12 month, and 14 (66.67%) of them maintained the ECT effect with medical treatment only and without readmission. CONCLUSION: This study showed that the ECT could be a useful treatment option for schizophrenic patients who are resistant to antipsychotics.

Adjunctive Treatment with Aripiprazole for Risperidone-Induced Amenrrhea / 대한정신약물학회지

OBJECTIVE: Hyperprolactinemia and associated side effect, amenorrhea, often occur with risperidone treatment. We investigated the effect of adjunctive treatment with aripiprazole on risperidone induced amenorrhea in female patients with schizophrenia. METHODS: A retrospective chart review of 24 female patients with adjunctive aripiprazole treatment for risperidone induced amenorrhea between August 2008 and July 2009 was conducted. The information collected included age, menstrual cycle, duration of no menstruation, prolactin level (before aripiprazole treatment and after regaining menstruation), dose of risperidone and aripiprzole, time from starting aripiprazole adjunctive treatment to regaing menstruation. The Student's t-test, Pearson's Chi-square test were used for data analysis. RESULTS: Mean percent decrease in prolactin level for all aripiprazole-treated patients was 71.4+/-8.6%. 85.7% (18/21) of patients resumed menstruation, while 14.3% (3/21) did not regain. In patients with regaining menstruation, mean time from starting aripiprazole to restarting menstruation was 6.6+/-2.4 weeks, mean dose of aripiprazole was 12.2+/-3.9 mg/day (dose range, 5 mg to 20 mg/day). Aripiprazole dose for regaining menstruation was not significantly correlated with baseline prolactin level. CGI score was not significantly changed after aripiprazole treatment. The cutoff point of prolactin level significantly increasing amenorrhea was 40 ng/mL. CONCLUSION: Adjunctive aripiprazole treatment is very effective to treat risperidone induced amenorrhea in female patients with schizophrenia.

Effects of Antipsychotics-Induced Amenorrhea on Attitudes Toward Treatment and Quality of Life in Women with Schizophrenia / 대한정신약물학회지

OBJECTIVE: This study was aimed to identify the correlation between antipsychotics-induced amenorrhea, and attitudes toward treatment and quality of life in women with schizophrenia. METHODS: Twenty female schizophrenic patients with antipsychotics-induced amenorrhea and thirty female schizophrenic patients without antipsychotics-induced amenorrhea were evaluated. Attitudes toward treatment were assessed by the Korean version of Drug Attitude Inventory (KDAI-10) and quality of life was assessed by the Korean version of World Health Organization Quality of Life Assessment Instrument-BREF (WHOQOL-BREF). The psychopathology of each patient was assessed by the Positive and Negative Syndrome Scales and the Clinical Global Impression-Severity. Adverse effects were evaluated using the Drug-Induced Extrapyramidal Symptoms Scale. Correlation analysis and multiple linear regression were conducted. RESULTS: The KDAI-10 score was not significantly correlated antipsychotics-induced amenorrhea. In WHOQOL-BREF score, social relation domain only showed significant correlation with antipsychotics-induced amenorrhea. Multiple linear regression analysis revealed that the number of family members contributed significantly to the Positive Subjective Feelings Scores of KDAI-10 and marital status contributed significantly to the social relation domain of WHOQOL-BREF in amenorrhea group. CONCLUSION: The results of present study suggest that antipsychotics-induced amenorrhea lower part of the quality of life domain in women with schizophrenia. Clinicians must pay attention to treatment of amenorrhea and various factors that correlated with attitudes toward treatment and quality of life in women with schizophrenia.

The Effect of CYP2D6/3A5 Genotypes on Plasma Concentrations of Haloperidol after Adjunctive Treatment of Aripiprazole

OBJECTIVES: To evaluate the drug interactions between aripiprazole and haloperidol, authors investigated plasma concentrations of those drugs by genotypes. METHOD: Fifty six patients with a confirmed Diagnostic and Statistical Manual of Mental Disorders 4th edition diagnosis of schizophrenia were enrolled in this eight-week, double blind, placebo-controlled study. Twenty-eight patients received adjunctive aripiprazole treatment and twenty-eight patients received placebo while being maintained on haloperidol treatment. Aripiprazole was dosed at 15 mg/day for the first 4 weeks, and then 30 mg for the next 4 weeks. The haloperidol dose remained fixed throughout the study. Plasma concentrations of haloperidol and aripiprazole were measured by high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) at baseline, week 1, 2, 4 and 8. *1, *5, and *10 B alleles of CYP2D6 and *1 and *3 alleles of CYP3A5 were determined. The Student's T-test, Pearson's Chi-square test, Wilcoxon Rank Sum test and Logistic Regression analysis were used for data analysis. All tests were two-tailed and significance was defined as an alpha < 0.05. RESULTS: In the frequency of CYP2D6 genotype, *1/*10 B type was most frequent (36.5%) and *1/*1 (30.8%), *10B/*10B (17.3%) types followed. In the frequency of CYP3A5 genotype, *3/*3 type was found in 63.5% of subjects, and *1/*3 type and *1/*1 were 30.8% and 5.8% respectively. The plasma levels of haloperidol and its metabolites did not demonstrate significant time effects and time-group interactions after adjunctive treatment of aripiprazole. The genotypes of CYP2D6 and 3A5 did not affect the plasma concentration of haloperidol in this trial. No serious adverse event was found after adding aripiprazole to haloperidol. CONCLUSION: No significant drug interaction was found between haloperidol and aripiprazole. Genotypes of CYP2D6 and 3A5 did not affect the concentration of haloperidol after adding aripiprazole.

The Effect of Cognitive-behavioral Characteristics on Depression of Caregivers in Brain-injured Patients

OBJECTIVE: To evaluate the relationship between depression and cognitive-behavioral characteristics of caregivers using social problem solving inventory (SPSI), social support or conflict scale (SSS or SCS) and somatic symptoms (SS). METHOD: Fifty five couples of brain-injured patients and caregivers participated in this study. We conducted a questionnaire survey of caregivers with Beck depression index (BDI), SPSI, SSS, SCS and SS for cognitive-behavioral characteristics. And also we studied demographic factors of patients and caregivers, clinical features of brain-injured patients, care- giving duration and time per day through interview and review of medical records. The statistical analyses were performed by independent t-test, one-way ANOVA, Pearson correlation test and linear regression analysis-stepwise method. RESULTS: BDI of the caregivers showed a negative correlation with SPSI, SSS, patients' MMSE and caregivers' education level, also a positive correlation with SCS, SS and patients' GDS (p<0.05). And married caregivers showed more depressive mood (p<0.05). Of these factors, the most influencing factors on BDI were GDS and SCS through linear regression analysis (p<0.01). CONCLUSION: MMSE, GDS and education level as cognitive- mental factors rather than physical and economic strain had a statistical correlation with depression of caregivers. Especially, SPSI, SSS and SCS as cognitive-behavioral characteristics should be considered on evaluation of depression of caregivers and will be helpful for successful rehabilitation for patients and caregivers.

Cerebellar Cognitive Affective Syndrome After Posterior Inferior Cerebellar Artery Territory Infarction

A number of brain imaging and human lesion studies suggest an involvement of the cerebellum in various cognitive functions. A 60-year-old woman developed dizziness due to cerebellar infarction. One month later, she developed cognitive decline, delusion, irritability, impulsive and violent behavior. Cognitive and behavioral symptom onset, neuroimaging findings and neuropsychological test led us to the diagnosis of cerebellar cognitive affective syndrome.

Effects of Chronic Alcohol Exposure on Dopaminergic and Serotonergic Neurotransmission System in Rat / 대한정신약물학회지

OBJECTIVE: This study investigates the effects of chronic alcohol exposure on rat brain THmRNA expression, TH (tyrosine hydroxylase) acitivity, and TPH (tryptophan hydroxylase) activity which are important in synthesis of dopamine and serotonin and other components of both the dopaminergic and serotonergic systems of the rat brain. METHODS: Rats were fed a liquid diet containing alcohol for 4 weeks. We investigated effects of chronic alcohol exposure on dopaminergic systems as follows. We evaluated expression of THmRNA in LC, VTA and substantia nigra by using in-situ hybridization and measured activity of TH by using immunoassay. We used HPLC for simultaneous measurement of dopamine, DOPAC and HVA in the cerebral cortex, striatum, hypothalamus, hippocampus, mid brain, hind brain, and cerebellum. Also we investigated serotonergic systems as follows. We evaluated expression of TH mRNA in the dorsal raphe nucleus by using radioprobe and measured the activity of TPH by using enzyme immunoassay. We used HPLC for simultaneous measurement of 5-HT and 5-HIAA in the cerebral cortex, striatum, hypothalamus, hippocampus, mid brain, hind brain, and cerebellum. RESULTS: Alcohol exposure for 4 weeks increased the expression of TH mRNA in the ventral tegmental area and the locus ceruleus but not in the substantia nigra. The 4 weeks of alcohol exposure did not cause significant changes in levels of dopamine and metabolites in the different areas of the brain, nor was it associated with changes in the maximal binding and affinity (Kd) of anterior striatal dopamine D2 receptor. Alcohol exposure for 4 weeks had no effect on the expression of TPH mRNA or on the activity of TPH in the dorsal raphe nucleus and the hypothalamus. CONCLUSION: We reported at first that chronic alcohol exposure could increase TH mRNA in the locus ceruleus. In a previous study of acute alcohol treatment, there is increase of dopamine metabolism but in this study, we did not observe any changes in dopamine metabolism in the different areas of the brain. Also we did not see any significant changes in the synthesis and metabolism of serotonin after 4 weeks of chronic alcohol exposure compared with control. Therefore, synthesis and metabolism of serotonin was affected in the acute phase. And, as previous reports have suggested, any changes caused by alcohol returned to previous levels via adaptation and regulatory mechanisms.

Association between Serotonin Transporter Polymorphism and the Effect of Atypical Antipsychotics on Serum Glucose and Lipids / 대한정신약물학회지

OBJECTIVE: The author investigated the association between the genotype distribution of 5-HTTLPR and the effects of atypical antipsychotics on serum glucose and lipids in schizophrenic patients. METHODS: Study subjects were 66 schizophrenic patients taking atypical antipsychotics (risperidone, olanzapine, clozapine, quetiapine, zotepine). The control group consisted of 82 schizophrenic patients taking typical antipsychotics (haloperidol). All subjects were medicated for at least 12 weeks. The author examined serum fasting blood sugar (FBS), HbA1c, total cholesterol, triglyceride, and the genotype distribution of 5-HTTLPR in all subjects. The presence of the 5-HTTLPR gene was determined by using polymerase chain reaction of genomic DNA with primers flanking the promoter regions of the 5-HTT gene. Between group comparisons of the genotype distribution and the effects of antipsychotics on the serum glucose and lipid levels were performed by using score test for t-test, one way ANOVA, and chi-square test. RESULTS: There was a significant increase in FBS level in all patients taking atypical antipsychotics except for those treated with risperidone. However, there was no statistically significant correlation between 5-HTTLPR genotype distribution and the effect of atypical antipsychotics on FBS, HbA1c, total cholesterol, and triglyceride serum levels in schizophrenic patients. CONCLUSION: These results suggest that 5-HTTLPR polymorphism has no significant association with the effect of atypical antipsychotics on serum glucose and lipids in Korean schizophrenic patients.

Association of Antipsychotic-Induced QTc Prolongation with 5-HTTLPR

OBJECTIVE: A Comparison of QTc prolongation for various antipsychotics and an analysis of QTc prolongation for the various types of serotonin transporter polymorphism were performed. METHOD: EKG was checked, followed by QTc measurement as Bazett's correction, and the serotonin transporter polymorphism was examined in 110 chronic schizophrenia patients were performed EKG before 24 weeks ago. We defiened QTc prolongation as over 450ms. The risk factor of sudden cardiac death were defiend as QTc prolongation and or 60ms in delta value. RESULT: The prevalence of QTc prolongation in this study was 7.3%, and the prevalence of over 60ms was 4.5%. Patients who had the risk factors were 10(9.1%). 6/52 who prescribed atypical antipsychotics and 2/58 who prescribed haloperidol showed QTc prolongation. The prevalence who had the risk factor of sudden cardiac death were 16% in atypical antipsychotics group, 3.4% in haloperidol group. QTc prolongation were observed more frequently in l/l type than s/s type. l allele frequency were 50% in QTc prolongated group, 19% in not prolongated group. l allele had an association with QTc prolongation(p<0.01). CONCLUSION: The prevalence of QTc prolongatin was frequent in chronic schizophrenia patients who were prescribed atypical antipsychotics. It has strong association with l allele of 5-HTTLPR.

No Association between Negative Symptoms of Schizophrenia and 5-HTTLPR / 대한정신약물학회지

OBJECTIVE: 5-HTTLPR (5-HT transporter-linked polymorphic region), located in the promoter region of 5-HT transporter gene, was reported to be associated with several neuropsychiatric illnesses. In this study, we investigated the genotype distribution and allele frequency of serotonin transporter gene 5-HTTLPR in schizophrenic patients and normal controls using an independent Korean sample. METHODS: Subjects were 156 schizophrenic patients fulfilling the DSM-IV criteria for schizophrenia who had taken antipsychotics for at least 6 months and 96 normal controls who had no past and family history of psychiatric illnesses. Two negative symptoms of PANSS, blunted affect and emotional withdrawal, were rated in all patients by two experienced psychiatrists. We examined the genotype distribution and allele frequency of the serotonin transporter gene 5-HTTLPR in all subjects, using polymerase chain reaction (PCR) of genomic DNA with primers flanking the promoter regions of the 5-HTT gene. Between-group comparisons of the genotype distribution and allele frequency were performed by using score test for trend, Fisher's exact test, and chi-square test. RESULTS: There was no significant difference in 5-HTTLPR genotype distribution and allele frequency between schizophrenic patients and normal controls. There was also no significant difference in 5-HTTLPR genotype distribution and allele frequency between schizophrenic patients with and without the two negative symptoms, blunted affect or emotional withdrawal, respectively. CONCLUSION: These results suggest that 5-HTTLPR polymorphism had no significant association with schizophrenia and negative symptoms in a Korean sample.
