  • Bipolar disorder is a mental illness characterized by extreme mood and behavioral swings, such as highs of euphoria and lows of depression. It is a socially significant disorder in which people with the disorder experience intense mood swings and, for those with severe bipolar disorder, it is even difficult leading a normal life. High stress levels in people with mental illness can lead to neuroendocrine disruption, and it is strongly linked to aging. When the neuroendocrine system becomes vulnerable to these mental illnesses and stress, it is likely to accelerate aging. And it's the epigenetic clock that can measure the extent of this accelerated aging. The Epi clock, a pan tissue clock, measures aging through DNA methylation, and the degree of methylation is modified and changed by environmental conditions in the body. Therefore we wanted to check the changes in the epigenetic age of the patients with bipolar disorder. While we found no significant differences in epigenetic age, we did confirm the possibility that people with bipolar disorder have different methylation than normal people. We also found that the EPIC array data fit better on the Epi clock than on the Horvath clock with age-accelerated data from normal people.

  • Objectives: This study was conducted to review studies on somatization disorder in traditional Chinese medicine. Methods: We reviewed studies in the China National Knowledge Infrastructure (CNKI) to 2017. Keywords were 軀體化障碍, Somatization disorder, somatic symptom disorder. We included Randomized Controlled Trial (RCT), and excluded non-Randomized Controlled Trial (nRCT), non-related somatization disorder or traditional Chinese medicine, non-clinical trials, dissertations for degrees. Jadad scale and Cochrane Library's Risk of Bias (RoB) were used for assessment of the quality of studies. Results: Twelve studies were selected. The Chinese Classification of Mental Disorders-3 (CCMD-3) was most frequently used as diagnostic criteria for somatization disorder. As for outcome measurement, Hamilton Rating Scale for Depression (HAMD) was used most commonly. Meta-analysis of 10 studies revealed effective rate of Chinese Herbal Medicine groups (CHM) was significantly higher than Western Medicine groups (WM) (RR: 1.14, 95% CI: 1.02 to 1.27, p=0.02, $I^2=40%$). There was no significant difference in effective rate of CHM+WM and WM (RR: 1.12, 95% CI: 0.84 to 1.49, p=0.46, $I^2=83%$). And also, effective rate of Acupuncture group (Acu) revealed no significant difference compared to that of WM (RR: 1.17, 95% CI: 0.95 to 1.44, p=0.13, $I^2=84%$). For HAMD, there was significant difference in CHM vs, WM group and Acu vs. WM group. Quality of selected 12 RCTs was low. Conclusions: Therapies practiced in traditional Chinese medicine may be effective options for somatization disorder. treatment. For further clinical studies in Korean medicine, this study could be groundwork for development of diagnosis and treatment on somatization disorder.

  • A survey was carried out to investigate the symptoms and occurance of reproductive disorder in Hanwoo(Korean native cattle). Data of the reproductive disorder of 561 heads from 28 farm households have been collected from Dec. '95 to Nov. '96 and analyzed calving no, nutritional body condition and housing forms. The results obtained are summarized as follows: 1. The incidence of reproductive disorder was 20.1% and the major common symptoms were repeat breeding(39.8%), anestrous(31.0%), nymphomania(10.6%) and subestrous(8.9%). 2. The incidence of reproductive disorder according to the calving no., that of heifer, calved one to two calving no. and over three calving no. were 20.6%, 13.9% and 34.5%, respectively. 3. Reproductive disorder incidence according to the nutritional body condition was 18.3%, 14.6% and 48.7% at body condition score(BCS) less than 2.0, 2.5 to 3.0 and over than 3.5, respectively. At BCS over 3.0, the symptoms of common reproductive disorder were repeat breeding(17.6%), anestrous(12.2%), nymphomania(10.8%) and subestrous(2.7%). 4. The incidence of reproductive disorder according to the housing form 15.8% and 34.6% for group feeding in open house and individual stanchion feeding in stall, respectively. In group feeding, reproductive disorder incidence of cows raised in space of more than 9.9$m^2$ per head was 14.1%, while that of cows raised less than 9.9$m^2$ per head was 18.2%. And incidence of repeat breeding, aneestrous and subestrous was more frequent in individual stanchion feeding than group feeding.

  • Purpose: The purpose of this study was to investigate the relationship between the risk of school bullying victimization and the risk of Internet gaming disorder according to gender in adolescents. Methods: The data of 1,920 middle school students collected at the baseline of the Internet user Cohort for Unbiased Recognition of gaming disorder in Early Adolescence (iCURE) study were analyzed. For statistical analysis, $x^2$ test, t-test and stratified multiple logistic regression analysis were conducted using SAS 9.4. Results: The prevalence rate of Internet gaming disorder of middle school boys was greater than that of girls (Boys: 9.9%, Girls: 6.2%). The greater the risk of school bullying victimization, the greater both the risk of Internet gaming disorder and the average daily time spent on Internet gaming. In girls, the relationship between the experience of being bullied in school and Internet gaming disorder was not statistically significant. However, the boys who had been bullied in school were 3.2 times more vulnerable to the risk of Internet gaming disorder than those without such experience (95% CI: 1.135-8.779). Conclusions: When considering interventions for Internet gaming disorder for adolescents, bullying victimization should be taken into account as well. Particularly, relieving stress related to bullying victimization can be important for boys with Internet gaming disorder.

  • Most articles of Reactive Attachment Disorder reported Disinhibited Type children adopted from other countries. Reports from only Turkey and Korea focused on Inhibited Type of Reactive Attachment Disorder children whom raised by their own parents and whose symptoms are very similar to Autistic Disorder. Since articles of treatment of Reactive Attachment Disorder, especially for Inhibited Type are very rare, this article informed the author's experiences of treatment for Korean Reactive Attachment Disorder children since 1987. To treat Reactive Attachment Disorder patients and their parents, three important areas must be included : 1) to make a therapeutic environment for a Reactive Attachment Disorder child, 2) to make an attachment between Reactive Attachment Disorder child and his/her mother through individual play therapy, filial therapy, and group therapy with sibling or peer, 3) to catch up developmental delay by speech therapy, cognitive therapy and therapeutic education. This treatment methods can be more easily and more effectively applied to Korean patients than other methods from western countries including USA or England.

  • Objectives : It is reported that panic disorder is frequently comorbid with other psychiatric illnesses. The aim of this study was to investigate differences of psychiatric comorbidity according to age of onset of panic disorder. Methods : Three hundred-two patients participated in the study. All the patients were evaluated by clinical instruments for the assessment the presence of other comorbid psychiatric disorders and various clinical features; Korean version of Mini International Neuropsychiatric Interview, Self-report questionnaires(Beck Anxiety Inventory, Beck Depression Inventory, Anxiety Sensitivity Index and State-Trait Anxiety Inventory) and clinical rating scale (Hamilton Anxiety Scale, Hamilton Depression Scale and Global Assessment of Functional score). Chi-square test was used to determine the difference between early onset and late onset panic disorder. Results : Forty percent of panic patients were found to have at least one comorbid psychiatric diagnosis. There were no differences among the groups divided by number of comorbidity in sex, agoraphobia comorbidity, duration of panic disorder, except onset age of panic disorder. Early onset group had more comorbidy with social phobia, agoraphobia, PTSD. We also found that Early onset panic disorder patients were more likely to experience derealization, nausea, parethesia than late onset panic disorder patients. Conclusion : The results of our study are in keeping with previous data from other parts of the world. Our finding suggest that earier onset of panic disorder related to more psychiatric comorbidity.

  • Objective : Despite the chronic nature and high social costs, individuals with anxiety disorders seldom seek treatment. Thus, education for public awareness and screening for the illness is tremendously important for mental health professionals. This study summaries and presents the results from Anxiety Disorder Screening Program during the Mental Health Exposition held in Seoul in April, 2013. Methods : We analyzed the data from 116 participants who agreed and completed the screening questionnaires during their visits to two-day Anxiety Disorder Screening Program prepared by the Korean Academy of Anxiety Disorder. The questionnaire comprised of modified Mobility inventory for agoraphobia, Contents of worries, Penn State Worry Questionnaire, Life Events Checklist, and Abbreviated Posttraumatic Stress Disorder Checklist. Results : Participants demonstrated high rates of anxiety symptoms and possible anxiety disorders. Experience of panic attack was reported by 45%, lifetime and 16% in the past month by respondents. Phobia was reported by 46%. Participants had an average of 3.3 pathological worries and among those, social or interpersonal content was most common (46%). At least one lifetime traumatic event was reported by 64%. By the cut-off scores in the literature, 46% had possible generalized anxiety disorder and 58% possible posttraumatic stress disorder. Conclusion : Our results suggested that many visitors to Anxiety Disorder Screening Program were in fact treatment seeking after experiencing some forms of anxiety symptoms. Further efforts for delivery of medical information and increasing public awareness for anxiety disorders are needed.

  • Objectives We investigated whether the catechol-O-methyltransferase (COMT) and serotonin related gene polymorphisms may be associated with agoraphobia in patients with panic disorder in Korea. Methods The COMT gene (rs4680), 5-hydroxytryptamine (serotonin) transporter linked polymorphic region (5-HTTLPR) gene (rs25531), serotonin receptor 1A (HTR1A) gene (rs6295) genotypes were analyzed in 406 patients with panic disorder and age-sex matched 206 healthy controls. Patients with panic disorder were dichotomized by the presence of agoraphobia. The following instruments were applied : the Beck Depression Inventory, the Beck Anxiety Inventory, the Panic Disorder Severity Scale. Results There was a significant difference in the distribution of 5-HTTLPR genotype between panic patients with agoraphobia and without agoraphobia (p = 0.024). That is, the panic patients with agoraphobia had a significant excess of the less active 5-HTTLPR allele (S allele). (p = 0.039) Also, we replicated previous western reports which indicated a significant difference in the distribution of COMT genotype between the patients with panic disorder and the healthy controls (p = 0.040). However, no significant associations of agora-phobia or panic disorder with HTR1A gene polymorphisms were found. Conclusions This result supports that the COMT polymorphisms may be associated with panic disorder and suggests that the 5-HTTLPR polymorphisms may play a role in the pathogenesis of agoraphobia in the Korean patients with panic disorder.

  • Neurocognitive research focusing on cognitive deficits in Depression has resulted in several important but yet potentially contradictory findings. Much literature documents the presence of significant neurocognitive impairments in depressive patients. Studies have shown that dysthymic disorder patients demonstrate a diffuse pattern of cognitive impairment which is frequently indistinguishable from that of focal braindamaged patients. Some reports have suggested that there is a focal pattern of deficit, such as anterior cingulate dysfunction, frontal lobe impairment, or dysfunction of the temporal-limbic cortex. The aim of this study is to evaluate the neurocognitive functions in dysthymic disorder patients, and to compare the functions with those of major depressive disorder patients. The subjects are 17 dysthymic disorder patients. And their neurocognitive functions are compared with those of 23 major depressive episode patients. Patients with a history of neurologic disease, alcohol dependence, substance abuse and mental retardation are excluded. They are assessed with a part of Vienna Test System which is computerized neurocognitive function tests and can evaluate attention, eductive ability, reproductive ability, visuoperceptual analysis, vigilance, visual immediate memory, the speed of information-processing, judgement, and fine motor coordinations. There are no other specific difference between two groups, except the result of cognitrone test. This study provides information about the neurocognitive functions and some difference between major depressive disorder patients and carefully diagnosed dysthymic disorder patients.

  • Reactive disorder is a group of diagnosis with a definitely known etiology and whose etiological factor is essential to the diagnosis. In DSM system, such reactive disorders are listed as adjustment disorder, acute stress disorder, brief psychotic disorder with marked stressor and posttraumatic stress disorder (PTSD). However, a growing number of individuals is suffering from a prolonged feeling of embitterment after exceptional negative life events and this condition could be diagnosed neither PTSD nor adjustment disorder nor depressive disorder in the context of DSM-IV diagnostic system. This clinical condition can be described as 'posttraumatic embitterment disorder' (PTED). PTED is a reactive disorder triggered by exceptional, though normal negative life events such as conflict in the workplace, unemployment, death of a relative, divorce, severe illness, or experience of loss or separation. The common feature of such events is that they are experienced as unjust, as a personal insult, accompanied by psychological violation of basic beliefs and values. The central psychopathological response pattern in PTED is a prolonged feeling of embitterment. In particular, the core emotion of embitterment can lead to the rejection of treatment. Therefore, "wisdom therapy" as a new treatment approach specifically designed for PTED has been developed. It is assumed that many patients suffering from PTED are often misunderstood and misdiagnosed. This review would help to introduce PTED into the clinical field in psychiatry.
