Intolerance of uncertainty (IU) is defined as the tendency to react negatively on an emotional, cognitive, and behavioral level to uncertain situations and events. However, this definition is somewhat categorical and does not explain the phenomenology of IU. Intolerance of uncertainty scale (IUS), the standard measure of IU, was considered to have two factors : 'unacceptability and avoidance of uncertainty' and 'uncertainty leading to the inability to act'. IU may be a cognitive vulnerability factor for clinical worry and generalized anxiety disorder (GAD). A number of moderators and mediators including cognitive avoidance, experiential avoidance and rumination influence the relationship between IU, worry, obsessive-compulsive symptoms, anxious and depressive symptoms. IU may be more strongly related to the symptoms of GAD than to symptoms of other anxiety disorders including obsessive-compulsive disorder (OCD), and major depressive disorder. IU may serve as an important transdiagnostic feature across anxiety and depressive disorders. Incorporating IU-specific treatment components into therapeutic protocols may result in pervasive benefits, and not only for those with GAD or OCD, but for people with any anxiety disorder or with depression.

Objective : This study was designed to examine the volumetric abnormality of orbitofrontal cortex (OFC) and its change after 2 years of pharmacotherapy in obsessive compulsive disorder (OCD) patients. Method : Volumetric magnetic resonance imaging studies were conducted in 15 OCD patients and 13 normal volunteers. For 2 years, all patients took at least one serotonin reuptake inhibitor and atypical antipsychotics were used as an augmentation therapy in most patients. The follow-up MRI studies were conducted after the pharmacotherapy and OFC volumes were measured by the manual region of interest method. Results : Bilateral OFC volumes of 15 OCD patients were significantly greater than those of the normal volunteers before the treatment. After 2 years of the treatment, significant decrease was observed in bilateral OFC volumes of OCD patients to the extent that left OFC volume of OCD patients was not different from that of the normal volunteers. Conclusion : This finding suggests that OFC is directly related to the pathophysiology of obsessive compulsive disorder.

지난 10년간 소아-청소년기 강박장애의 발병율, 유병율, 병태생리, 치료방법에 대한 연구가 급속도로 증가하고 있는 추세에 있다. 하지만, 아직까지 소아-청소년기 발병 강박장애가 성인기 발병 강박장애와 다른 유형의 장애인지에 대해서는 논란의 소지가 많다. 최근의 뇌영상자료, 유전자료, PANDAS 연구 결과, 약물 치료결과에 대한 연구들을 종합해 보면, 소아-청소년기 발병 강박장애는 성인기 발병장애와는 구별되는 독특한 특성을 지닌 새로운 아형으로 이해해야 할 것으로 생각된다. 소아청소년기 강박장애가 갖는 독특한 특성은 틱장애의 높은 공존유병율, 강박장애-틱장애의 높은 가족력, 뇌영상에서 나타나는 지저핵 이상의 일관성 등을 생각할 수 있으며, 또한 다른 유형으로 연쇄구균 감염 후 자기면역기전과 연관되어 발생한다고 생각되는 PANDAS 등이 있다. PANDAS나 소아기 발병 강박장애는 모두 기존의 강박장애 치료제인 SSRI 단독 치료에는 낮은 반응성을 보이는 것으로 보고되고 있다. 이는 아마도, 장애의 병태생리적 기전의 차이, 즉 소아기 발병의 경우 도파민 시스템의 장애가 동반되어 있는 것과 관련이 있을 것으로 생각된다. 본 논문에서는 이러한 배경에 근거하여, 소아-청소년기 발병 강박장애의 특성을 요약하고, 이들 중 특히 일반적인 치료에 저항적인 환자군에 대한 치료 전략에 대해 논하였다. 강박장애의 임상적 다양성을 고려할 때, 소아-청소년기 강박장애를 강박장애의 새롭고 다른 아형으로 이해하고 접근하는 것은, 강박장애의 원인, 병태생리, 치료의 기전을 이해하는 데에 보다 새롭고 폭넓은 시각을 제시해 줄 것으로 생각한다.

본 연구의 목적은 중국에서 강박증 치료에 삼전요법이 얼마나 효과가 있는지 살펴보는 것이다. 삼전요법은 도교, 불교 선종은 물론 고대 한방정신요법의 특색을 두루 담고 있는 심리치료 방법이다. 최근 국내 연구 결과에 따르면 전체 인구의 1.5%가 강박증을 앓고 있어 강박증 치료에 많은 관심이 쏠리고 있다. 중국의 임상연구 결과에 따르면 삼전요법과 양약치료를 병행한 경우 강박증 치료에 유의미한 효과를 얻었다. 삼전요법 치료만으로도 양약치료보다 강박증에 유의한 치료 효과를 거두었다. 강박증 치료를 위해 삼전요법의 활성화가 필요하다.

Objectives : There is a paucity of data on the long-term course of obsessive-compulsive disorder (OCD) and chronological relationship between OC symptoms and their related symptoms such as anxiety and depression. The purpose of this study was to investigate the longitudinal course of OC symptoms as well as anxiety and depression which are believed to be associated with OC symptoms. Methods : Data for 155 patients with OCD who completed general evaluation for OCD were used. Forty four were excluded to minimize the effect of the different age of onset on the clinical course. One hundred eleven patients finally participated in the analysis. Cross-sectional correlations between each symptom as well as between such symptoms and the duration of illness were analyzed. Further correlation analysis was done within two groups that were divided by 7 years of the duration of illness. Results : There were significant correlations not only between the severity of OC symptoms and anxiety but also between anxiety and depressive symptom, regardless of the duration of illness. These correlations between such symptoms were also found within patients with the duration of illness below 7 years, whereas these were not within the group with the duration of illness above 8 years. Conclusion : Patients with OCD in this study shows the moderate to severe level of OC symptoms irrespective of the duration of illness. Our finding also suggests that the OC symptoms, especially obsessions are closely related to anxiety and depressive symptoms and these relationships might be pronounced in relatively early phase of the OCD after onset.

Objective : Impaired working memory has been known to play an important role in the pathophysiology of obsessive-compulsive disorder (OCD) with growing evidence. Delayed matching-to-sample task (DMST) is a working memory task which have an advantage in analyzing several different working memory processes in one task. However, most of the studies have failed to reveal the working memory impairment with the DMST. The aim of this study was to identify whether working memory deficit in OCD can be evaluated with the DMST. Methods : The participants included 20 OCD patients and 20 healthy volunteers. Working memory was evaluated with the DMST with two different working memory loads. Accuracy of response and mean response time were measured. Results : OCD patients showed a significantly longer reaction time and lower accuracy in DMST compared to healthy controls in the task with high working memory loads. Moreover, the difference in accuracy showed interaction with the working memory load. Conclusion : The present results indicate that working memory deficit in patients with OCD can be evaluated with the DMST. The findings also suggest that previous negative behavioral results using the DMST were from low working memory load of the task.

The fluoxetine is one of the most frequently prescribed drugs for the treatment of depression and obsessive-compulsive disorder(OCD). This has been known as one of the most safest medication. But since the advent of this drug, there have been several reports of side effects-the mania and suicidal ideation-encountered during coadministration of fluoxetine with or without other psychotropic drugs. We experienced a case of 20 years old male OCD patient who developed into abrupt manic state and also was preoccupied with intense suicidal ideation following fluoxetine use. He was a only child in his family and his father had a history of alcoholism about 15years ago. Our patient's obsessive-compulsive symptoms have been occured since puberty. His OCD symptoms and anxiety were aggravated since joining the army. Beside these facts, we could not find any other psychiatric history such as depressive disoder and bipolar disorder. We used the fluoxetine starting dosage of 20mg and increased to 40mg at second week. About 3 weeks after the treatment, he developed sudden manic symptom and more aggravated suicidal ideation without any OCD symptoms. He felt vitalized and energetic without having enough sleep and food. These symptoms were ceased over two weeks by stopping medication. Up to this point, the reason why fluoxetine induces mania and suicidal preoccupation is unclear. But somehow the fluoxetine has effects on serotonin receptor and serotonin-dopamine regulations, thus we could make an assumption that fluoxetine can induce mania, extrapyramidal symptoms(EPS) and suicidal ideation in some part of the serotonin unbalanced patients. We think this would be the first report to remark on fluoxetine's suicidal and manic side effects in Korea. So here we present the case with the summary of reviewed articles.

Objectives : The purpose of this study to provide preliminary data to effective halitosis control. Methods : A survey was carried out the self-perception of causative factors of halitosis in 98 female college students in Chungnam province. In addition, the levels of oral gas and breath gas were measured by use of the B&B checker, and an analysis was made of the correlation between halitosis and obsessive-compulsive disorder (OCD). Results : 1. Subjective halitosis awareness degree different degree of dryness, 'None', 'some', 'little' people who feel as the 'little fly' (68%), 78.3%, 70% was higher (p<0.05), halitosis interest 'very worried', 'worry', 'normal' person with a' not at all 'to 58.3% higher (p<0.01). 2. In regard to OCD severity, 49.0%, 34.7% and 16.3% were found to be mild, moderate and severe respectively. Halitosis tended to be severe in proportion to OCD severity, which was statistically significant (p<0.05). 3. Oral gas had a positively correlation with breath gas (r=0.329, p<0.01), but had a negative one with OCD severity (r=0.204, p<0.05). Conclusions : Symptoms of oral dryness and halitosis interest were associated with self-perception of halitosis. The levels of oral gas and breath gas were in inverse proportion to OCD severity. Hereat, it needs to analyze psychogenic factors properly as regards the diagnosis or treatment of halitosis.

Obsessive-compulsive disorder (OCD) is a mental disorder in which a person repeated a particular thought or feels. The domain of beliefs and guilt predicted OCD symptoms. Although there were some neuroimaging studies investigating OCD symptoms, resting-state functional magnetic resonance imaging (rs-fMRI) study investigating intra-network functional connectivity associated with guilt for OCD is not reported yet. Therefore, in the current study, we assessed the differences between intra-network functional connectivity of healthy control group and OCD group using independent component analysis (ICA) method. In addition, we also aimed to investigate the correlation between changed functional connectivity and guilt score in OCD. Total 86 participants, which consisted of 42 healthy control volunteers and 44 OCD patients, acquired rs-fMRI data using the 3T MRI. After preprocessing the fMRI data, a functional connectivity was used for group independent component analysis. The results showed that OCD patients had higher score in emotion state in beliefs and lower functional connectivity in fronto-parietal network (FPN) than control group. A decrease of functional connectivity in FPN was negatively correlated with feelings of guilt in OCD. Our results suggest excessive increase in guilt negatively affect to process emotional state and behavior or cognitive processing by influencing intrinsic brain activity.
