목 적：본 연구에서는 주요우울장애를 동반한 공황장애 환자들과 동반하지 않은 공황장애 환자들을 대상으로, 환자들이 경험하는 공황장애의 임상 양상 및 증상의 심각도의 차이를 확인하고, 주관적인 증상 평가 이외에 불안을 나타내는 생리적 지표인 자율신경계 기능의 차이도 함께 알아보고자 하였다. 방 법：DSM-IV 진단 기준으로 공황장애 환자들에서 주요우울장애가 공존하는 것으로 진단된 19명과 주요우울장애가 공존하지 않는 것으로 진단된 60명을 대상으로 첫 외래 방문시 공황 증상으로 인한 고통 정도와 회피 정도를 측정하는 기본 기록지와 기타 자기 보고식 설문지를 실시하였으며, 자율 신경계 기능을 평가하기 위해서 객관적, 생리적 지표로 Heart Rate Variability(HRV)를 측정하고 환자들이 경험하는 공황장애의 심각성을 평가하기 위해 임상가들에 의해 Clinical Global Impression(CGI)과 Panic Disorder Severity Scale(PDSS)을 시행하여 객관적으로 평정하였다. 자료 분석을 위해 환자들이 보고한 각 임상 척도 점수 및 임상가 평정 점수를 주요우울장애가 공존하는 공황장애 환자군과 그렇지 않은 공황장애 환자군에 따라 t-test를 통해 비교하고, 두 집단간 HRV 양상을 비교하기 위해서 연령을 공변인으로 설정하고 ANCOVA를 실시하였다. 결 과：주요우울장애가 동반된 공황장애 환자들은 공황장애로만 진단된 환자들에 비해 주관적으로 호소하는 우울이나 불안 수준이 더 높았으며, 불안 민감도나 신체 증상에 대한 예민성도 더 많이 호소하는 경향이 있었다. 또한 부정적인 일상생활에서 자신을 비하하고 낙담하게 하는 부정적인 자동적 사고 경향이 더 높았으며, 자기 자신을 고양하고 미래를 희망적으로 지각하는 긍정적인 자동적 사고 경향은 더 낮은 것으로 나타났다. CGI와 PDSS와 같은 객관적 평정 척도에서도 우울증이 동반된 공황장애 환자들의 증상 심각도가 더 높은 것으로 나타났다. 반면, 주요우울장애를 동반한 환자들의 심박 변이도가 보다 낮은 경향이 있었지만 두 군사이에 통계적으로 유의한 차이는 없었다. 결 론：본 연구 결과로 주요우울장애를 동반한 공황장애 환자들이 공황장애만을 지닌 환자들에 비해 임상 양상이 심하고 더 많은 고통을 겪는다는 것을 알수 있었다. 그러나 HRV 지표에서는 두 집단간 유의한 차이가 관찰되지 않았다. 향후 더 많은 대상자를 포함한 연구가 시행된다면 주요우울장애의 동반 여부에 따른 자율신경계 기능의 차이에 대해 더 많은 이해가 가능하리라고 기대된다.

Purpose: The purpose of this study is to examine the association between each phase of the Life Transition Process (LTP) and depressive symptoms among parents of children with Autism Spectrum Disorder (ASD). Methods: Using a cross-sectional study design, data pertaining to LTP and depressive symptoms were collected from 285 parents of children with ASD (101 fathers and 184 mothers). Participants were recruited through the Autism Society of Korea and a counseling center for families of children with ASD. Results: Using a cut-off point of 5 or higher on the Beck Depression Inventory-Short Form, more than half of the parents (53.4%) were deemed depressed; these parents experienced moderate (27.4%) to severe (11.6%) levels of depressive symptoms. A hierarchical multiple regression using the socio-demographic characteristics of children and parents and each phase of the LTP as predictors, found that lower income (${\beta}=-.14$, p=.007) and greater scores for the wandering phase (${\beta}=.59$, p<.001) were significant predictors of greater levels of depressive symptoms. Conclusion: These findings confirm the association between LTP and depressive symptoms for parents of children with ASD, who were found to have a greater risk of depressive symptoms during wandering phase.

Object : Currently, the alteration of cytokine system has been known to play an important role in regard to depressive symptom. We focused on the relationship between immunological parameters and clinical improvement in major depressive disorder. Method : Data were collected on 26 patients with major depressive disorder using a 8-week prospective follow-up design. After 8-week treatment period with fluoxetine, patients were classified into a response group and a non-response group according to their psychopathological outcome as evaluated by Hamilton Depression Rating Scale. The differences of the immunological parameters between pre-treatment phase and post-treatment phase were compared among patients. The difference of those was also compared within each phase among them. The relationship between socio-demographic variables, depression, cytokine, mononuclear cells was examined by correlation analysis. Multiple regression analyses were performed to explore the predictors of clinical improvement of major depressive disorder. Result : Pre-treatment levels of IL-$1{\beta}$ in the response group were significantly higher than those in the non-response group. Pre-treatment levels of IL-$1{\beta}$ of all patients and in the response group were positively correlated with pre-treatment monocyte counts. Patients with subsequent remission showed significantly lower IL-6 values at baseline than those with non-response. Post-treatment values of IL-6 did not differ significantly among the patients. The correlation test showed more frequent relations among cytokines and mononuclear cells in the response group than in the non-responder group. Especially, serum level of IL-6 in pre-treatment phase was only significantly correlated with HAMD score after 8-week treatement phase, while other cytokines and mononuclear cells were not. Pretreatment level of IL-6 was of paramount importance in predicting clinical improvement of depressive symptom. Conclusion : The immune system of major depressive disorder patients might dichotomize the patients into subsequent responders and non-responders. Immune system might be of great influence on the clinical improvement of major depressive disorder. The mode of interaction between depression and cellular immune function and the mediators responsible for the cytokine production need to be studied further.

Objective : Panic disorders are frequently accompanied by major depressive disorder (MDD). There is insufficient information about which clinical factors in panic disorder are associated with comorbid MDD. The aim of this study is to identify clinical factors related with comorbid MDD in patients with panic disorder. Methods : Two experienced psychiatrists diagnosed panic disorder based on DSM-IV criteria. This diagnosis in the 275 subjects was confirmed again by Mini-International Neuropsychiatric Interview (MINI). Lifetime comorbid psychiatric diagnoses were examined by MINI. The Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA) and Panic Disorder Severity Scale (PDSS) were used to assess the severity of depressive, anxiety and panic symptoms. Results : The result of MINI showed that 95 patients (34%) with panic disorder satisfied the diagnosis of MDD. Multivariate logistic regression model showed that comorbid generalized anxiety disorder (GAD) and the symptom of "fear of losing control or going crazy" were associated with MDD in patients with panic disorder. In female patients, the "chills or hot flushes" symptom was also associated with comorbid MDD. Conclusion : These results showed that coexisting GAD and certain symptoms of panic are associated with comorbid MDD.

Objectives: A growing number of people depend on flexible employment, characterized by outsider employment status and perceived job insecurity. This study investigated whether there was a synergistic effect of employment status (full-time vs. part-time) and perceived job insecurity on major depressive disorder. Methods: Data were derived from the 2012 Canadian Community Health Survey-Mental Health of 12 640 of Canada's labor force population, aged 20 to 74. By combining employment status with perceived job insecurity, we formed four employment categories: full-time secure, full-time insecure, part-time secure, and part-time insecure. Results: Results showed no synergistic health effect between employment status and perceived job insecurity. Regardless of employment status (full-time vs. part-time), insecure employment was significantly associated with a high risk of major depressive disorder. Analysis of the interaction between gender and four flexible employment status showed a gender-contingent effect on this link in only full-time insecure category. Men workers with full-time insecure jobs were more likely to experience major depressive disorders than their women counterparts. Conclusions: This study's findings imply that perceived job insecurity may be a critical factor for developing major depressive disorder, in both men and women workers.

Objectives : This study was conducted to examine whether there are qualitative differences in attention problem among children with various psychiatric disorders, including attention-deficit hyperactivity disorder (ADHD), depressive disorder, anxiety disorder, and tic disorder using clinical ADHD diagnostic system (ADS) T-scores. Methods : The subjects were 794 outpatient children aged from 5 to 15 years, including 540 children with ADHD, 95 children with depressive disorder, 86 children with anxiety disorder, and 73 children with tic disorder. Clinical T-scores on the ADS were calculated using the mean and standard deviations of four ADS variables for the ADHD group. Results : All four groups had T-scores on the ADS in the abnormal range. However, when comparing the clinical T-scores, the children with depressive and anxiety disorders performed better than the children with ADHD. We also found that although the four groups seemed to be similar in terms of clinical T-scores for omission and commission errors, there were significant differences in clinical T-scores for reaction time and the standard deviation of response time (RT) between the ADHD and other groups. Conclusions : We concluded that inattention and impulsivity might not be specific only to ADHD and that the clinical T-scores of RT and standard deviation of RT on the ADS could be used to discriminate between ADHD and other clinical groups.

Objectives: This study was conducted to compare the mothers' rearing attitude of ADHD children and that of children with depressive disorder. Methods: The participant consisted of 58 school-aged children diagnosed as ADHD, 14 children diagnosed as depressive disorder based on DSM-IV criteria. Normal control group consisted of 34 school-aged children who are free of any diagnosis of psychiatric disorders. Parental Acceptance-Rejection Questionnaire, Parenting Style Questionnaire, Children's Depression Inventory, Marital Satisfaction Scale, Beck's Depression Inventory were administered to all children and their mothers. Results: The parents of ADHD children showed more aggressive/hostile, neglecting/indifferent and less warm/affectionate parenting styles to their children than those of the depression and control groups. The depressive group perceived their parents as more rejecting than the control groups. Conclusion: The externalizing symptoms of ADHD might provoke parental distress and make it difficult for the parents to show positive rearing attitude toward their children. The depressive children might be more sensitive and perceptive to the negative sign of their parents' rearing attitude.

Major depressive disorder is characterized by cellular and molecular alterations resulting in the depressive behavioral phenotypes. Preclinical and clinical studies have demonstrated the deficits, including cell atrophy and loss, in limbic and cortical regions of patients with depression, which is restored with antidepressants by reestablishing proper molecular changes. These findings have implicated the involvement of relevant intracellular signaling pathways in the pathogenetic and therapeutic mechanisms of depressive disorders. This review summarizes the current knowledge of the signal transduction mechanisms related to depressive disorders, including cyclic-AMP, mitogen-activated protein kinase, Akt, and protein translation initiation signaling cascades. Understanding molecular components of signaling pathways regulating neurobiology of depressive disorders may provide the novel targets for the development of more efficacious treatment modalities.

We reviewed clinical studies investigating the pharmacological treatment of major depressive episodes (MDEs) with mixed features diagnosed according to the dimensional criteria (more than two or three [hypo]manic symptoms+principle depressive symptoms). We systematically reviewed published randomized controlled trials on the pharmacological treatment of MDEs with mixed features associated with mood disorders, including major depressive disorder (MDD) and bipolar disorder (BD). We searched the PubMed, Cochrane Library, and ClinicalTrials.gov databases through December 2017 with the following key word combinations linked with the word OR: (a) mixed or mixed state, mixed features, DMX, mixed depression; (b) depressive, major depressive, MDE, MDD, bipolar, bipolar depression; and (c) antidepressant, antipsychotic, mood stabilizer, anticonvulsant, treatment, medication, algorithm, guideline, pharmacological. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We found few randomized trials on pharmacological treatments for MDEs with mixed features. Of the 36 articles assessed for eligibility, 11 investigated MDEs with mixed features in mood disorders: six assessed the efficacy of antipsychotic drugs (lurasidone and ziprasidone) in the acute phase of MDD with mixed features, although four of these were post hoc analyses based on large randomized controlled trials. Four studies compared antipsychotic drugs (olanzapine, lurasidone, and ziprasidone) with placebo, and one study assessed the efficacy of combination therapy (olanzapine+fluoxetine) in the acute phase of BD with mixed features. Pharmacological treatments for MDEs with mixed features have focused on antipsychotics, although evidence of their efficacy is lacking. Additional well-designed clinical trials are needed.

Objective: This study was performed to report the effect of traditional Korean medicine as a treatment for laryngopharyngeal reflux (LPR) combined with depressive and anxiety disorder. Methods: We treated this patient with traditional Korean medicine and measured symptom severity using the reflux symptom index (RSI), Beck depression inventory (BDI), and Beck anxiety inventory (BAI). Results: After 3 weeks of treatment, most symptoms had decreased. The RSI score dropped from 21 to 8, BDI from 27 to 14, and BAI from 29 to 15. Conclusions: Traditional Korean medicine may be effective as a treatment for LPR combined with depressive and anxiety disorder, and a correlation may exist between LPR and psychological factors. However, more rigorous studies are required to identify exactly what treatment is most efficient for relieving LPR combined with depressive and anxiety disorder and whether LPR and psychological factors are clearly correlated.
