RESUMEN
“Comfort women” are survivors of sexual slavery by the Imperial Japanese Army during World War II, who endured extensive trauma including massive rape and physical torture. While previous studies have been focused on the trauma of the survivors themselves, the effects of the trauma on the offspring has never been evaluated before. In this article, we reviewed the first study on the offspring of former “comfort women” and aimed to detect the evidence of transgenerational transmission of trauma. In-depth psychiatric interviews and the Structured Clinical Interview for DSM-5 Axis I Disorders were conducted with six offspring of former “comfort women.” Among the six participants, five suffered from at least one psychiatric disorder including major depressive disorder, panic disorder, posttraumatic stress disorder, adjustment disorder, insomnia disorder, somatic symptom disorder, and alcohol use disorder. Participants showed similar shame and hyperarousal symptoms as their mothers regarding stimuli related to the “comfort woman” issue. Increased irritability, problems with aggression control, negative worldview, and low self-esteem were evident in the children of mothers with posttraumatic stress disorder. Finding evidence of transgenerational transmission of trauma in offspring of “comfort women” is important. Future studies should include more samples and adopt a more objective method.

RESUMEN
OBJECTIVE: Some clinical studies have found alterations in the levels of serum brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF) after applying antidepressant treatment in patients with major depressive disorder (MDD). We evaluated the serum BDNF and GDNF levels before and after 12 weeks of antidepressant treatment in MDD outpatients. METHODS: Serum BDNF and GDNF levels were measured in 23 female MDD outpatients at baseline and after 12 weeks of treatment. The severity of depression was measured with the Hamilton Depression Rating Scale-17 (HAMD-17). Remission of MDD to the treatment was defined as a posttreatment HAMD-17 score of <7. RESULTS: Among MDD patients, 19 (82.6%) subjects were in mild to moderate depression. The whole MDD patients had significantly higher serum BDNF and GDNF levels at baseline than those after 12 weeks of antidepressant treatment. The baseline serum BDNF and GDNF levels did not significantly between the remission and nonremission groups. The significant alteration in both BDNF and GDNF levels after antidepressant treatment were observed in patients with remission. CONCLUSION: The present study suggests that the baseline serum BDNF and GDNF levels are higher than the posttreatment levels in some mild-to-moderate MDD outpatients and the significant alteration in BDNF and GDNF level after treatment were observed in patients with remission.

OBJECTIVE: Little is known about the psychiatric complications or risk factors for depression in suspected or confirmed Middle East Respiratory Syndrome (MERS) patients quarantined in hospital. METHODS: A retrospective chart review was performed of all the patients admitted to the acute MERS inpatient unit at the NMC during the 2015 outbreak. RESULTS: 30 (75%) were confirmed to be MERS-CoV positive among 40 admitted cases. Among the 24 MERS survivors, 17 (70.8%) exhibited psychiatric symptoms and 10 (41.7%) received a psychiatric diagnosis and medication during their hospital stay. Suspected MERS patients did not exhibit psychiatric symptoms or receive a psychiatric diagnosis. 27 suspected or confirmed MERS patients (age 41.15±18.64, male 37.0%) completed psychological assessments. A multiple linear regression analysis revealed that the Korean National Health and Nutrition Examination Survey-Short form and the Impact of Event Scale-Revised scores were significantly positively correlated with Patient Health Questionnaire-9 scores. CONCLUSION: Our findings indicate that the acute treatment of MERS-CoV infections in quarantine had a significant impact on the patients’ mental health. Furthermore, assessment of the risk factors for depression may identify vulnerable patients who require psychiatric care and attention during hospital quarantine.

“Comfort women” refers to young women and girls who were forced into sexual slavery by the Imperial Japanese military during World War II. They were abducted from their homes in countries under Imperial Japanese rule, mostly from Korea, and the rest from China, Philippines, Malaysia, Taiwan, Indonesia, the Netherlands, etc. “Comfort women” endured extreme trauma involving rape, sexual torture, physical abuse, starvation, threats of death, and witnessed many others being tortured and killed. This article reviews all the studies that have investigated the psychiatric or psychosocial sequelae of the survivors of the Japanese military sexual slavery. Most importantly, a recent study which conducted a psychiatric evaluation on the former “comfort women” currently alive in South Korea is introduced. The participants’ unmarried rate was relatively high and their total fertility rate was relatively low. Majority of the participants reported having no education and being the low economic status. They showed high current and lifetime prevalence of posttraumatic disorder, major depressive disorder, somatic symptom disorder, social anxiety disorder, panic disorder, and alcohol use disorder. Participants showed high suicidality and majority of the participants still reported being ashamed of being former “comfort women” after all these years. This article high-lights the fact that the trauma has affected the mental health and social functioning of former “comfort women” throughout their lives, and even to the present day.

OBJECTIVE: The aim of the present study was to provide clinical consensus and evidence regarding initial treatment strategies for the pharmacological treatment of social anxiety disorder (SAD) in Korea. METHODS: We prepared a questionnaire to derive a consensus from clinicians regarding their preference for the pharmacological treatment of SAD in Korea. Data regarding medication regimens and psychotropic drugs used during initial treatment, the doses used, and the pharmacological treatment duration were obtained. Responses were obtained from 66 SAD experts, and their opinions were classified into three categories (first-line, second-line, third-line) using a chi-square analysis. RESULTS: Clinicians agreed upon first-line regimens for SAD involving monotherapy with selective serotonin reuptake inhibitors (SSRIs) or the serotonin-norepinephrine reuptake inhibitor (SNRI) venlafaxine, or combined therapy using antidepressants with betablockers or benzodiazepines on a standing or as-needed basis. First-line psychotropic drug choices for initial treatment included the following: escitalopram, paroxetine, sertraline, venlafaxine, and propranolol. The medication dosage used by domestic clinicians was found to be comparable with foreign guidelines. Domestic clinicians tended to make treatment decisions in a shorter amount of time and preferred a similar duration of maintenance treatment for SAD when compared with foreign clinicians. CONCLUSION: This study may provide significant information for developing SAD pharmacotherapy guidelines in Korea, especially in the early stage of treatment.

OBJECTIVE: The aims of this study were to determine whether childhood maltreatment contributes to the occurrence of major depressive disorder (MDD) with bipolarity, and whether there is a relationship between central serotonergic activity, as assessed using loudness dependence of auditory evoked potentials (LDAEP), and childhood maltreatment. METHODS: Thirty-five MDD patients were stratified according to the presence or absence of childhood trauma into two subgroups, childhood trauma (CT) and no childhood trauma (NCT), using the Korean version of the Childhood Trauma Questionnaire (K-CTQ). The CT group was subjected to further analysis. Several psychometric ratings were also applied. In addition, auditory processing for the loudness dependence of auditory evoked potentials (LDAEP), which was used as a marker of serotonergic activity, was measured before beginning medication. RESULTS: There was a significant difference in total Korean Bipolar Spectrum Disorder Scale score between the CT and NCT groups (t=-2.14, p=0.04). The total K-CTQ score was positively correlated with the total Beck Scale for Suicidal Ideation (BSS) score (r=0.36, p=0.036). In particular, emotional abuse was positively correlated with the total Barratt Impulsiveness Scale (r=0.38, p=0.026), BSS (r=0.38, p=0.025), and Hamilton Depression Rating Scale (HAMD) (r=0.36, p=0.035) scores. There was also a positive correlation between LDAEP and total Hypomania Personality Scale (r=0.49, p=0.02) and HAMD (r=0.58, p=0.004) scores within CT group. CONCLUSION: The findings of this study support that there is a relationship between childhood maltreatment and bipolarity in patients with MDD.

OBJECTIVE: The serotonin transporter (5-HTT) genes are major candidate genes for modulating the suicidal behavior. We investigated the association between serotonin transporter polymorphisms and suicidal behavior in patients with major depressive disorder (MDD). METHODS: Serotonin transporter intron 2 VNTR polymorphism (5-HTTVNTR) and serotonin transporter linked polymorphic region polymorphism (5-HTTLPR) were analyzed in 132 depressed patients with suicidal attempt as well as in 122 normal controls. Hamilton's 17-item Depression Rating Scale (HDRS), the Risk-Rescue rating system (RRR) and the Lethality Suicide Attempt Rating Scale updated (LSARS-II) were assessed for the depressed patients. RESULTS: Although not statistically significant, a trend was found such that the 10/10 and 10/12 alleles of 5-HTTVNTR were more common in suicidal subjects than in control subjects. Comparing allele frequency, those with a 10 allele or 10 allele carriers were higher in suicidal subjects than in control subjects. No difference was noted in 5-HTTLPR genotypes and haplotype distribution between the suicidal subjects and control subjects. The RRR scores in subjects with the 10/10 5-HTTVNTR genotype or 10 5-HTTVNTR allele were significantly lower than those in subjects with other genotypes. CONCLUSION: These results show the possibility that 10 allele of 5-HTTVNTR is related to suicidal behavior in the suicidal subjects with MDD and suggest that 12 allele of 5-HTTVNTR might be related to more lethality in the suicidal subjects with MDD.

OBJECTIVES: Quality of life (QoL) was a important factor of treatment outcome in alcoholics. This study was to examine the relationship between family support and quality of life among alcoholics, to explore the moderating effect of abstinence self-efficacy on those relationship and to suggest practical implications for intervention services. METHODS: Data for this study were collected through the use of a survey instrument completed by 771 alcohol dependent admitted to inpatient treatment from 20 psychiatric hospital. Subjects were screened using the Family support, Drug Taking Confidence Questionnaire-8, World Health Organization Quality of Life Assessment Instrument. Collected data were analysed by moderated multiple regression and simple slope analysis. RESULTS: Family support was directly associated with QoL. Also the abstinence self-efficacy had moderating effects on relationship between family support and QoL. Simple slope analysis showed that the effects of family support on QoL were significant at low and high levels of abstinence self-efficacy and especially the effects of family support on QoL were more higher at the high levels of abstinence self-efficacy. CONCLUSION: This findings suggest that abstinence self-efficacy is an important factor to QoL among alcohol dependents. Increasing self-efficacy, family support will be improve the QoL and recovering process. Based on these findings suggest practical intervention.

OBJECTIVES: The aim of this study was to explore clinical factors or high-risk factors associated with occurrence of delirium tremens (DT) during acute alcohol withdrawal in inpatients with alcohol dependence. METHODS: This study included 164 inpatients seeking treatment for acute alcohol withdrawal in the detoxification unit. All subjects were evaluated prospectively for known risk factors for DT and their occurrence of DT. Correlations were determined between risk factors obtained at admission and development of DT. RESULTS: Among all subjects, 42 patients (25.6%) suffered from delirium tremens within seven days after admission. DT patients had more severe alcohol withdrawal symptoms, the presence of past DT, and higher levels of aspartate aminotransferas, alanine aminotransferase, gamma-glutamyl-transpeptidase, and homocysteine, compared with patients who did not suffer DTs. According to results of a multiple regression, occurrence of DT showed correlation with the following factors at admission: tremor, a past history of DT, higher homocysteine level, and nausea and vomiting. CONCLUSION: Development of DT showed correlation with symptoms of severe alcohol withdrawal, past history of DT, and higher homocysteine level. Among these, a severity of alcohol withdrawal symptoms and a history of DT are factors that can be easily evaluated on the day of admission in order to predict the potential for occurrence of DT.

OBJECTIVES: Many studies have suggested different neurobiological findings and clinical courses in alcoholism. Recently, subtyping in alcohol dependence has become essential to overcome the heterogeneity of patients. Among several criteria of subtypes, Lesch's typology is proposed to integrate biological, social, and psychological factors. This review provides neurobiological findings and treatment-responses of alcohol dependence according to Lesch's typology. METHOD: We searched the international published medical literature using the search terms 'Lesch's typology' and 'alcohol dependence' and using the limits 'human'. RESULTS: We identified 17 studies with subjects of alcohol dependence according to Lesch's typology. CONCLUSION: They indicated that each subtype of Lesch's typology can have specific neurobiological factors and different clinical responses as follows. Lesch's subtype 1 is characterized by severe withdrawal symptoms and associated with elevated glutamate and homocysteine. Lesch's subtype 2 is defined by individuals who drink alcohol as self-medication for anxiety. Their craving has significant positive correlations with prolactin, leptin level, or intake-volume (vasopressin). Lesch's subtype 4 is related to cerebral dysfunction and associated with increased glutamate and left-handedness. Clinical trials showed that naltrexone was effective in Lesch's subtype 3 and 4 patients, while acamprosate was effective in the subtypes 1 and 2.

OBJECTIVE: Hyperprolactinemia is common side effect associated with antipsychotics use. Nevertheless, hyperprolactinemia is relatively neglected by clinician. Especially, there is no study related to amisulpride-induced hyperprolactinemia in korea. This study aimed to determine whether amisulpride can be induced hyperprolactinemia in Korean psychiatric patients. METHODS: This study methodology consisted of a retrospective review of medical charts and prolactin levels. Serum prolactin levels were measured in 24 Korean patients(12 males and 12 females) with psychosis who were treated over 400mg of amisulpride per day. RESULTS: All patients had hyperprolactinemia. Prolactin levels significantly increased after receiving amisulpride(z=-3.702, p=0.000). The prolactin level was significantly higher in females(156.29+/-63.75ng/mL) than in males(69.04+/-39.91ng/mL) after administering amisulpride(p=0.000). There was a correlation between dosage and prolactin levels(r=0.61, p=0.002). However, there was no correlation between duration of treatment and prolactin levels. CONCLUSIONS: Antipsychotics, especially amisulpride can increase serum prolactin levels and may results in short and long term side effects. Routine clinical assessment of initial and additional prolactin level and associated symptoms should be done.

Neurotrophic factors are critical regulators of the formation and plasticity of neuronal networks. Brain-derived neurotrophic factor (BDNF) is abundant in the brain and periphery, and is found in both human serum and plasma. Animal studies have demonstrated that stress reduces BDNF expression or activity in the hippocampus and that this reduction can be prevented by treatment with antidepressant drugs. A similar change in BDNF activity occurs in the brain of patients with major depression disorder (MDD). Recently, clinical studies have indicated that serum or plasma BDNF levels are decreased in untreated MDD patients. Antidepressant treatment for at least four weeks can restore the decreased BDNF function up to the normal value. Therefore, MDD is associated with impaired neuronal plasticity. Suicidal behavior can be a consequence of severe impaired neuronal plasticity in the brain. Antidepressant treatment promotes increased BDNF activity as well as several forms of neuronal plasticity, including neurogenesis, synaptogenesis and neuronal maturation. BDNF could also play an important role in the modulation of neuronal networks. Such a neuronal plastic change can positively influence mood or recover depressed mood. These alterations of BDNF levels or neuronal plasticity in MDD patients before and after antidepressant treatment can be measured through the examination of serum or plasma BDNF concentrations. BDNF levels can therefore be useful markers for clinical response or improvement of depressive symptoms, but they are not diagnostic markers of major depression.

OBJECTIVE: Serotonergic dysfunction is quite evident in panic disorder. We investigated whether the C(-1019)G polymorphism of 5-HT1A receptor gene may play a role in the pathogenesis of panic disorder in a Korean population. METHODS: The 5-HT1A receptor genotype for the single nucleotide polymorphism (SNP) C(-1019)G was analyzed in 94 patients and 111 healthy controls. The severity of the patients' symptoms was examined using the Spielberger State-Trait Anxiety Inventory (STAI), Panic Disorder Severity Scale (PDSS), Anxiety sensitivity index (ASI), Acute Panic Inventory (API) and Hamilton's Rating Scale for Anxiety (HAM-A). RESULTS: The distribution of the genotypes of the C/G polymorphism did not differ significantly from those predicted by Hardy-Weinberg equilibrium in patients as well as the controls. No association between the C(-1019)G polymorphism and panic disorder was detected in either the allele frequency or genotype distribution. There was no significant association with genotype distribution in the panic disorder with agoraphobia. However, there was a significant difference of symptom severity between C/C, C/G, and G/G genotype or between C and G allele in panic disorder patients without agoraphobia. PDSS scores were significantly higher in subjects with the G/G genotype or with G allele in patients without agoraphobia, not in total patients or patients with agoraphobia. CONCLUSION: Although there were no significant differences in the genotype and allele distributions, we found a significant association between panic symptom severity and the serotonin 1A receptor gene. This result suggests that the serotonin 1A receptor and serotonin may play a role in the pathogenesis of panic disorder.

Duloxetine is a balanced and potent serotonin and noradrenaline reuptake inhibitor (SNRI) and has adverse effects that are commonly associated with such drugs, including nausea, dry mouth, constipation, insomnia, and dizziness. Recently, duloxetine-induced liver injury has also been observed in patients with preexisting liver disease or chronic alcohol use. We investigated the effects of duloxetine in a healthy young adult with major depressive disorder (MDD) but no risk factors, and found that his total bilirubin level increased to 3.3 mg/dL and he developed jaundice after 5 months of duloxetine treatment. Discontinuation of duloxetine treatment saw his total bilirubin level decrease to 1.8 mg/dL. Thus, the administration of duloxetine might induce liver injury in a patient with MDD. However, the limitations of this single case report must be acknowledged. Although the cause of hepatic dysfunction in this case remains to be elucidated, clinicians should monitor liver function carefully after duloxetine treatment. Further investigations with a larger sample are needed.

Brain-derived neurotrophic factor (BDNF) is an important member of the neurotrophic factors, which are critical regulators of the formation and plasticity of neuronal networks. BDNF is abundant in the brain and periphery and it is found in both human serum and plasma. Stressed animals and depressed patients show reduced BDNF expression in the hippocampus and this reduction can be prevented by antidepressant drug treatment. Recent several clinical studies have indicated the decreases of serum or plasma BDNF levels in untreated patients with major depression. These decreases of BDNF can recover after antidepressant treatment. Increasing BDNF after antidepressant treatment could result from improving depressive symptoms, not just from antidepressant treatment. BDNF can play a critical role in the action mechanism of antidepressant treatment. Taken together, major depression may be considered a dysfunction of critical neuronal networks, and the gradual network recovery may induce antidepressant effect. Serum or plasma BDNF levels could indirectly show the above processes of major depression.

OBJECTIVES: Serum and plasma BDNF levels have been shown to be decreased in patients with mood disorder such as major depressive disorder and bipolar disorder. We investigated whether platelet BDNF levels would be lower in patients with acute bipolar manic episode compared with those of normal controls. METHODS: BDNF levels were examined in platelet-rich plasma(PRP) and platelet-poor plasma(PPP) in 20 healthy controls and 20 hospitalized patients who were diagnosed as bipolar I disorder, most recent episode manic using a Structured Clinical Interview for DSM-IV. And severity of manic symptoms was measured using Young Mania Rating Scale(YMRS). Platelet BDNF level was calculated by subtracting PPP BDNF from PRP BDNF level, and dividing the result by the total platelet count, and it was expressed as pg/10(6) platelet. RESULTS: Platelet BDNF levels were significantly lower in patients with acute bipolar manic episode(4.55+/-3.36pg/10(6) platelet) than in normal controls(6.84+/-2.32pg/10(6) platelet)(p=0.008). However we failed to reveal the significant negative correlation between platelet BDNF levels and YMRS scores in patients with acute bipolar episode. CONCLUSION: Our finding suggests that there is a decrease in the platelet BDNF of patients with acute bipolar manic episode.

OBJECTIVE: To examine gender differences in the characteristics of suicidal behavior in South Korea. METHODS: Between August 2003 and December 2006, 344 suicide attempters (116 men, 228 women) participated in this study. The attempters were interviewed using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), and the lethality of the attempt was measured using the Lethality Suicide Attempt Rating Scale-II (LSARS-II) and Risk-Rescue Rating Scale (RRRS). RESULTS: Significantly more women than men were admitted to emergency rooms due to attempted suicide during the study period. The male attempters were older and had a higher rate of employment than the females. Depression was the most common psychiatric disorder in both genders. The lesion/toxicity scores of the RRRS indicated that the male suicide attempters used higher doses or more toxic agents than the female attempters. The most common methods of suicide were ingestion and cutting in both sexes. Although there were significant gender differences in the RRRS risk score and RRRS total scores, there was no gender difference in the LSARS-II scores, which suggests that patients of both sexes share a similar ambivalence regarding suicide completion or death. CONCLUSION: Our study should be understood within the context of the specific cultural background of South Korea. We found that males and females use similar methods when attempting suicide and share a similar ambivalence regarding the outcome of the attempt; however, there was a difference in severity of the attempt between the two groups. Our findings may aid in the identification of more effective methods of intervention to prevent suicide.

OBJECTIVES: Several lines of evidence suggest the serotonergic dysfunction involved in the biological susceptibility of suicide. Tryptophan hydroxylase (TPH), the rate-limiting enzyme in the biosynthesis of serotonin, plays a vital role in serotonin metabolism. In a case-control study, we investigated whether the TPH gene was a susceptible factor for suicidal behavior in depressive patients. METHODS: The subjects were 218 depressed patients who attempted suicide and visited emergency rooms in multi-medical centers. One hundred thirty hospitalized non-suicidal depressed patients and the 161 normal controls were matched with the suicidal group. Individuals in all 3 groups were evaluated independently by a Structured Clinical Interview for the purpose of establishing a DSM-IV criteria diagnosis (SCID). The severity of depressive symptoms was evaluated using Hamilton depression rating scale (HDRS). RESULTS: There was no significant difference in genotype distributions and allele frequencies of TPH intron 7 A218C polymorphisms among 3 groups. Furthermore, no significant difference in genotype counts and allele frequencies of the polymorphisms was found among lethal suicidal depressed patients, non-suicidal depressed patients and the normal controls. CONCLUSION: This study suggests that the A218C polymorphism of the TPH gene is unlikely to have a major effect on the susceptibility of suicidal behaviors in depressive patients.

OBJECTIVE: This study was conducted to investigate the cognitive factors that can longitudinally predict the response to treatment in patients with schizophrenia. METHODS: The subjects were 49 patients with schizophrenia who were newly hospitalized in an acute psychiatry ward and had not been treated with medication for at least 8 weeks prior to the study. The symptoms and cognitive functions of the patients were evaluated at baseline before treatment (T0), at eight weeks after treatment (T1), and one year after treatment (T2). Clinical symptoms were assessed using the PANSS, and cognitive functions were estimated using the Vigilance Test, Cognitrone Test, Wisconsin Card Sorting Test (WCST), and the Korean version of the Memory Assessment Scales (K-MAS). RESULTS: The patient group showed marked impairments in cognitive function when compared to the normal group, but the patients' clinical symptoms and cognitive functions improved after drug treatment. The patients also showed consistent improvement in verbal and nonverbal memory function as time progressed. Furthermore, there was a significant correlation between clinical symptoms and cognitive functions in the patient group. The cognitive variables that best predicted treatment response and prognosis were total errors on the WCST and immediate list recall component of the K-MAS. It was also shown that the number of total errors on the WCST was a better cognitive predictor than the number of errors in immediate recall. CONCLUSION: The results of the present study show that the neurocognitive functions of patients with schizophrenia can be stabilized with treatment intervention, that treatment response is related to improvement in cognitive function, and that cognitive domains, especially executive function, can predict treatment response and prognosis in patients with schizophrenia.
