육기환,민성길,장순아 대한신경정신의학회 2001 신경정신의학 Vol.40 No.1

연구목적: 틱장애에서는 다른 정신장애가 공존하는 경우가 매우 많은데, 고통을 주는 증상으로 특히 주의력결핍과잉운동증상과 강박증상이 관심을 받아 왔다. 틱장애의 병태생리에 대한 연구에서 도파민계, 세로토닌계, 아드레날린계 등의 중추 모노아민계의 이상이라고 하며 강박증상과 주의력결핍 과잉운동증상도 도파민계, 세로토닌계, 아드레날린계의 이상이라고 하였다. 본 연구는 틱장애 아동군에서 주의력결핍 과잉운동장애나 강박장애의 공존유무에 따라 틱증상의 심각도에 차이가 있는지 알아보고 틱증사의 심각도와 공존증상에 따라 혈장 homovanillic acid(HVA)와 5-hydroxyindoleacetic acid(5-HIAA) 농도에 차이가 있는지 알아보고자 시행되었다. 방법: 본 연구는 50명의 만성 틱장애를 가진 환자를 대상으로 강박장애와 주의력결핍 과잉운동장애를 진단하였고 틱증상과 강박증상과 주의력결핍 과잉운동증상을 각각 Yale global tic severity scale(YGTSS).Leyton obsessional inventory-child version(LOI-CV), Conners parent rating scale로 평가하였으며 high performance liquid chromatography를 이용하여 혈장 HVA와 5-HIAA 농도를 측정하였다. 결과: 틱장애 전체 대상군에서 강박장애나 주의력결핍 과잉운동장애가 공존된 경우 58%였으며 두 장애가공존되어 있어도 틱증상의 정도와 혈장 HVA와 혈장 5-HIAA 농도에 차이는 없었다. 틱 증상의 정도가심할수록 혈장 HVA 농도와 정의 상관관계를 보였으나 혈장 5-HIAA 농도와는 상관성이 없었다. 강박증상의 저항과 방해척도는 혈장 5-HIAA 농도와 역 상관관계를 보였다. 결론: 틱장애에 강박장애나 주의력결핍 과잉운동장애가 공존되어 있어도 틱증상의 심각도에 영향을 주지 않았다. 틱증상의 심각도는 혈장 HVA 농도와 상관관계가 있고 혈장 5-HIAA 농도와는 상관성이 없어 틱증상은 도파민계의 이상과 관련있음이 시사된다. Objectives : Contemporary empirical studies have suggested high rates of comorbid attention-deficit hyperactivity disorder(ADHD) or obsessive compulsive disorder(OCD) in children with tic disorders. Not infrequently, ADHD or OCD is as source of greater impairment than are the tic symptoms. The studies in the pathophysiology of tic disorder have implicated abnormalities of dopamine, serotonin and norepinephrine. The studies in pathophysiology of ADHD or OCD also have implicated abnormalities of dopamine, serotonin and norepinephrine. This study was purposed to examine the differences in tic severities and in the levels of plasma homovanillic acid(HVA) and 5-hydroxyindoleacetic acid(5-HIAA) according to the presence of comorbid ADHD or OCD in patients with chronic tic disorders. Methods : In fifty chronic tic patients, OCD or ADHD was also diagnosed. And then tic symptoms, obsessive-compulsive symptoms, and attention-deficit hyperactive symptoms were assessed using Yale global tic severity scale(YGTSS), Leyton obsessional inventory-child version (LOI-CV), and Conners parent ration scale. The plasma HVA and 5-HIAA levels were measured using high performance liquid chromatography with electrochemical detection method. Results : Fifty-eight percent of the patients with chronic tic disorders had comobid ADHD or OCD. But severities of tic did not differ regardless of the presence of comorbid ADHD or OCD. There was a significant positive correlation between tic severities and plasma HVA levels but none between tic severities and plasma 5-HIAA levels. There was a significant inverse correlation between resistance and interferencd scores and plasma 5-HIAA levels. Plasma HVA levels showed significant positive correlations with plasma 5-HIAA levels. Conclusion : These results showed that tic severities didn't vary according to the presence of comorbidities, and that tic severities were correlated with plasma HVA levels, not with plasma 5-HIAA levels. These results suggested that the pathophysiology of chronic tic disorder was strongly correlated with abnormalities of dopaminergic system.

한국인이 생각하는 나르시시즘(Narcissism)의 개념에 대한 예비연구

이만홍,육기환 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.3

Objects : In order to define different concepts of narcissism in Korean, this study was designed to compare the concept of narcissism by Korean laymen with that of DSM-Ⅲ-R. Methods : 1) Initially, 2 laymen & 4 psychiatric personnel were interviewed and made to describe in free association on narcissism. With these results and the DSM-Ⅲ-R diagnostic criteria of narcissistic personality disorder, we developed a semistructured interview. 2) Using this semistructured interview, authors interviewed 28 key informants(14 laymen, 14 psychiatric residents) an asked them to describe their own understanding of prototypical person of narcissism. Psychiatric residents were comparative subjects to laymen. Results : Laymen thought positively that narcissism was one part of personality, made them achieve self-confidence and a new vitality in life, and consequently made them more enthusiastic in one's work. Narcissism was thught to result in possible difficulties of interpersonal relationships espeually by psychiatric residents. There was a gender difference which concentrated on the differences-men thought level of education, job, success, fame and money more important whereas women took as important factors such as appearance, relationships with one's spouse or lover and his social standing. Men overtly require acceptance by others whereas women self-absorption and intellectual achievement. When one is denied, men directly show aggressive response whereas women show this indirectly and later. Laymen saw narcissism as normal, while some saw it as a personality disorder or mental disorder. Reasons contribute to narcissism were developmental factor and socioenvironmental factor. Conclusions : Concepts and psychopathology of narcissism did not seem little difference between opinions of laymen and DSM-Ⅲ-R. Laymen took narcissism more positively than psychiatric residents. It was taken as part of personality, required for normal development and professional capabilities are above average and have achievement and self-confidence. Narcissism did not require treatment or when necessary it would become better. Results suggested that narcissism has sex difference more or less.

민성길,이호분,육기환,남궁희승,류경희 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.4

연구목적 : 본 연구는 인지행동적 집단치료를 문제행동을 보이는 청소년에 시행하여 청소년 문제행동과 폭력행동의 감소에 미치는 효과를 평가하고 효과에 영향을 주는 요인을 찾아 청소년 문제행동과 폭력행동에 대한 개입의 모델을 제시하려하였다. 방 법 : 교사들에 의해 문제행동을 보이는 학생으로 의뢰된 27명의 중학교 2학년 남녀학생들에게 15 회기에 걸친 인지행동적 집단치료를 시행하였다. 대조군은 같은 중학교 2학년 남녀 학생 20명으로 이들에게는 치료를 실시하지 않았다. 대상군과 대조군을 치료 전후에 자기기술형 비행척도, 폭력행동척도를 작성하게 하였으며, 담임 교사로 하여금 대상군에게 치료전후에 교사용 문제행동 척도, 문제행동 적발빈도 조사를 실시하였다. 결 과 : 1) 자기기술형 비행 척도, 폭력행동 척도로 평가한 결과 대상군에서는 치료 후에 비행이 유의하게 감소하였으며, 대조군과 비교하였을 때 양군간의 유의한 차이가 있었다. 2) 대상군에 대한 교사용 문제행동 척도, 문제행동 적발 빈도조사에서 치료 전후에 문제행동이 유의한 차이를 보이지 않았다. 3) 치료효과를 조별로 비교하면 자기 기술형 비행척도는 조별로 유의하게 차이를 보였고. 2조는 교사용 문제행동 적발 빈도 조사를 제외한 모든 척도에서 유의한 호전을 보였다. 4) 문제행동의 호전에 영향을 주는 요인은 대상군의 성별, 문제행동정도와 치료자였으며, 폭력 행동의 호전에 영향을 주는 요인은 대상군의 문제행동정도였다. 결 론 : 문제행동을 보이는 청소년을 대상으로 한 인지행동적 집단치료는 그들 스스로 평가한 문제 행동 감소의 효과는 있었으나, 교사가 평가하기에는 유의한 차이가 없었으며, 폭력행동에 대해서 특이한 효과는 보여 주지 못하였다. 하지만 대상군의 성별, 문제행동의 정도, 치료자에 따라서는 문제행동의 감소, 폭력행동의 감소 모두에 효과가 있었다. 이러한 결과는 대상군의 선정과 치료자의 숙련도에 따라서는 인지-행동치료가 청소년 문제행동과 폭력행동에 대한 적절한 치료 모델이 될 수 있음을 시사한다. Objectives : The purpose of this study was to examine the effect of cognitive-behavioral group therapy on improving adolescents' behavioral problems, especially violent behavior. Method : The subjects were 27 middle school students referred by their teachers for behavioral problems. We devided them into 4 teams and treated them for 15 sessions of cognitive-behavioral group therapy. The control group were 20 middle school students who had no cognitive-behavioral therapy. We assessed their behaviors pre-and post intervention by two series of scale, ie. self ratings and teacher ratings. Self ratings included 'misbehavior scales' and 'violent behavior subscale' ; teacher ratings included 'teacher-children rating scale' and 'detection of misbehavior scale'. Result : 1) In self-rating scales, the misbehavior of the subject group decreased more than the coltrol group, but not the violent scale. There were statistically significant group differences of improving effect in misbehavior scales. 2) In teacher rating scales, there was no significant decrease in the behavioral problems of the subject group. 3) By teams there were significant different intervention effects among 4 teams in self rating misbehavior scale. Team 2 improved on all scales except teacher-rating detection of misbehavior scale. 4) Determinant factors of intervention effect on behavioral problems were the degree of baseline behavioral problems, sex of subjects and therapist. Conclusion : The results from this study suggest that cognitive-behavioral group therapy was effective in decreasing the behavioral problems of adolescents. But the effect of therapy depends on sex, the degree of behavioral problems of subjects and the therapist.

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

Comparison of Laparoscopic and Open Gastrectomy for Patients With Gastric Cancer Treated With Neoadjuvant Chemotherapy: A Multicenter Retrospective Study Based on the Korean Gastric Cancer Association Nationwide Survey

Seul Ki Oh,Chang Seok Ko,Seong-A Jeong,Jeong Hwan Yook,유문원,Beom Su Kim,In-Seob Lee,Chung Sik Gong,Sa-Hong Min,Na Young Kim,Information Committee of the Korean Gastric Cancer Association 대한위암학회 2023 Journal of gastric cancer Vol.23 No.3

Purpose: Despite scientific evidence regarding laparoscopic gastrectomy (LG) for advanced gastric cancer treatment, its application in patients receiving neoadjuvant chemotherapy remains uncertain. Materials and Methods: We used the 2019 Korean Gastric Cancer Association nationwide survey database to extract data from 489 patients with primary gastric cancer who received neoadjuvant chemotherapy. After propensity score matching analysis, we compared the surgical outcomes of 97 patients who underwent LG and 97 patients who underwent open gastrectomy (OG). We investigated the risk factors for postoperative complications using multivariate analysis. Results: The operative time was significantly shorter in the OG group. Patients in the LG group had significantly less blood loss than those in the OG group. Hospital stay and overall postoperative complications were similar between the two groups. The incidence of Clavien–Dindo grade ≥3 complications in the LG group was comparable with that in the OG group (1.03% vs. 4.12%, P=0.215). No statistically significant difference was observed in the number of harvested lymph nodes between the two groups (38.60 vs. 35.79, P=0.182). Multivariate analysis identified body mass index (odds ratio [OR], 1.824; 95% confidence interval [CI], 1.029–3.234; P=0.040) and extent of resection (OR, 3.154; 95% CI, 1.084–9.174; P=0.035) as independent risk factors for overall postoperative complications. Conclusions: Using a large nationwide multicenter survey database, we demonstrated that LG and OG had comparable short-term outcomes in patients with gastric cancer who received neoadjuvant chemotherapy.
