We report a case of a large asymptomatic Rathke cleft cyst in a 14-year-old boy. This cyst was of considerable size, measuring 2x1.8x1.8 cm, but did not produce any symptoms and was confined to the suprasellar area. The cyst wall was lined by pseudostratified ciliated columnar epithelium with goblet cells. The lining epithelium of the Rathke cleft cyst was immnoreactive for cytokeratin, EMA and CEA.

Recently developed new classifications (Holland, Van Nuys, modified Lagios) of ductal carcinoma in situ (DCIS) linked to outcome have emphasized the importance of nuclear morphology rather than architecture. We have evaluated these three classifications in ductal carcinomas composed of in situ and invasive carcinomas. The reproducibility of three classifications was assessed (n=49), and the histological grade of the DCIS was compared with the histologic differentiation (modified Bloom & Richardson method) and nuclear grade (modified Black method) of the coexisting invasive ductal carcinoma (n=45). According to Holland classification, the DCIS component was poorly differentiated in 51.0%, intermediately differentiated in 40.8%, and well differentiated in 8.2%. Using the Van Nuys classification, the DCIS component was group 3 (high grade with or without necrosis) in 44.9%, group 2 (non-high grade with necrosis) in 28.6%, and group 1 (non-high grade without necrosis) in 26.5%. According to the modified Lagios classification, the DCIS component was high-grade in 42.8%, intermediate-grade in 32.7%, and low-grade in 24.5%. The histologic grades of the three classifications revealed significant correlations between Holland and Van Nuys classification (p<0.0001) and between Holland and modified Lagios classification (p<0.0001), especially in poorly differentiated/group 3/high-grade DCIS. The reproducibility of classification of the DCIS was 71.4% in the Holland, 61.2% in the Van Nuys, and 55.1% in the modified Lagios classifications. The grade of the DCIS showed significant correlation with the grade of coexisting invasive ductal carcinoma (p<0.0001), especially in poorly differentiated/group 3/high-grade DCIS. In conclusion, DCIS grade, determined by the Holland, Van Nuys or modified Lagios classifications, is closely correlated with the histologic grade of the invasive ductal component in tumors composed of in situ and invasive ductal carcinoma, and may be a useful factor to estimate clinical behavior of DCIS. In our experience the Holland classification is recommended for DCIS classification due to its high reproducibility.

PURPOSE: The aim of this study was to understand factors that influence post-traumatic stress (PTS) in Korean forensic science investigators. METHODS: A total of 111 forensic science investigators were recruited in Korea. PTS was measured using the tool modified by Choi (2001) from the original developed by Foa, Riggs, Dancu, and Rothbaum (1993) based on DSM-IV. Factors influencing PTS included demographic and job-related characteristics, emotional intelligence, and death anxiety. RESULTS: PTS scores were positively correlated with personality type, fatigue from work, and death anxiety. PTS scores were negatively correlated with length of career as a forensic science investigator and emotional intelligence. The factors that had the greatest influence on PTS were death anxiety, years spent as a forensic science investigator, personality type, emotional intelligence, fatigue, and homicide experience. The explanatory power of these six factors was 44.0%. CONCLUSION: Therefore, it is necessary to regularly evaluate the mental health of those who are vulnerable to PTS. Based on these results, various interventions could be implemented for promoting overall health of the forensic science investigators.

OBJECTIVE: This study was done to explore the relationship between circadian types, depressive mood, and sleep quality and to identify the mediating effect of depression between circadian types and sleep quality in shift work nurses. METHODS: Participants were 510 females selected by convenience sampling. Data were collected from October to November 2008 using the Composite Scale for Morningness, Beck Depression Inventory, and Pittsburgh Sleep Quality Index-Korean. The data were analyzed using descriptive statistics, Pearson correlation coefficients, logistic regression and multiple regression. RESULTS: There were significant relationships between sleep quality and circadian types(r=-0.160, p<0.001), and depressive mood (r=0.438, p<0.001). In addition, the circadian types was significantly correlated with depressive mood (r=-0.236, p<0.001). Depressive mood showed mediating effect between circadian types and sleep quality (beta=0.424, p<0.001). Evening type subjects showed higher scores in depressive mood and sleep quality than morning type ones. CONCLUSION: These results suggest that depression and circadian rhythm management in nurses with evening type would contribute to the prevention of sleep disturbance.

OBJECTIVE: We examined the relationship between chronotype and sleep disturbance, and assessed various factors that might be associated with sleep disturbance in Korean firefighters. METHODS: Self-administered questionnaires assessing chronotype, depression, alcohol use, posttraumatic stress disorder (PTSD), stress response and sleep quality were examined in 515 firefighters. RESULTS: Evening type firefighters more reported depression, alcohol use, PTSD, stress response and sleep disturbance. Also evening chronotype was the most significant risk factor for poor sleep quality (odds ratio [OR], 4.812; 95% confidence interval [CI], 2.448-9.459), even after controlling for all other variables (OR, 3.996; 95% CI, 1.806-8.841). CONCLUSION: Chronotype was the factor most strongly associated with sleep disturbance, and therefore should be considered an important variable in sleep quality, particularly in occupations involving stressful activities, such as firefighting.

OBJECTIVES : A neural circuit including amygdala, the hippocampal complex and prefrontal cortex was associated with deficits in facial processing in schizophrenia. These deficits have a significant impact on social functioning in schizophrenia. Both neuropsychological deficits and brain structural abnormalities in first-degree relatives of schizophrenia patients suggest that they may also have the deficit in facial information processing as genetic factors. The purpose of this study was to explore the dysfunction of facial information processing in first-degree relatives of schizophrenia patients using functional magnetic neuroimaging (fMRI). METHODS : Ten non-affected siblings of schizophrenic patients and 10 normal comparison subjects having no schizophrenic siblings underwent fMRI during the d ynamic facial change procedure consisting of presentations of facial emotion and gender discrimination stimuli. The emotion discrimination condition consisted of the presentation of 12 happy faces and 12 disgust/fear faces. The gender discrimination condition consisted of the presentation of 12 male faces and 12 female faces. Condition-specific brain activations were compared between non-affected siblings and normal comparison subjects RESULTS : The facial information processing related brain regions including fusiform gyrus, several areas of frontal, temporal, occipital, and cerebellar regions exhibited more activation during gender discrimination than emotion discrimination tasks in each group. During gender discrimination task, siblings of schizophrenic patients showed less activation in right fusiform gyrus, both middle and superior frontal gyrus, left cuneus, and left inferior frontal gyrus, compared with normal comparison subjects. CONCLUSION : Dysfunctional facial information processing, such as a deficit in gender discrimination, might be an endophenotype of schizophrenia.

Human herpesvirus-6 (HHV-6) often causes mild illnesses, but is rarely associated with encephalitis or other fatal neurological conditions. We report a girl who died of a intractable status epilepticus from HHV-6. A 14-month-old girl presented with focal motor seizures in right extremities evolving to generalized convulsive status epilepticus. She had a history of mild diarrhea for 4 days and high fever for 2 days. Although she was treated with lorazepam, phenytoin, phenobarbital, and continuous midazolam infusion, generalized seizures continued for 3 hours after arrival. She became seizure free, but remained unconscious and ended up to death at the 44 days of hospitalization. The CSF HHV-6 DNA PCR turned out to be positive.

PURPOSE: The purpose of this study was to investigate the effects of a simulation-based practice program on nursing students' self-efficacy, critical thinking disposition and problem solving process.METHOD: A quasi-experimental non-equivalent control group pre-post test, design was used. A total of 111 students, 53 students for the experimental group and 58 students for the control group. The experimental group participated in the program for 30 hours during 4 days. Data were analyzed using descriptive statistics, X2-test, Fisher's exact probability test, and t-test.RESULTS: The results showed that the simulation-based practice program significantly improved self - efficacy and critical thinking disposition of nursing students. However, there was no significant difference in the problem solving process.CONCLUSION: Therefore, to promote self-efficacy and critical thinking disposition in nursing students, it is necessary to actively use simulation-based practice program. To improve the problem solving process in the future, it is necessary to apply the simulation-based practice program to the nursing curriculum continuously and to use it considering sufficient education periods.

Journal of Korean Neuropsychiatric Association 2024;63(1):57-67
Objectives:
The purpose of this study was to examine the association between social capital and depression in adults in their 20s.
Methods:
The study used data from the Community Health Survey 2019 (CHS 2019). The CHS 2019 covered a representative sample of 229099 adults from 17 census tracts in the Republic of Korea, of which 19589 adults in their 20s were taken as subjects for this study. The subjects completed a survey with questions regarding demographic characteristics, built environment and social capital. The symptoms of depression were evaluated through the Patient Health Questionnaire (PHQ)-9. Multiple logistic regression was used to examine whether social capital was associated with depression.
Results:
The multiple logistic regression results indicated that social capital was associated with depression in adults in their 20s. When demographic characteristics and built environment were included in the analysis, trust, contact with relatives, contact with friends, and social activities were associated with depression in adults in their 20s.
Conclusion
A lack of social capital was associated with depression in Korean adults in their 20s. Our study suggests a need to look beyond individual factors to intervene in national and community social capital and prevent depression in adults in their 20s.

OBJECTIVE: The Connor-Davidson Resilience Scale (CD-RISC) measures various aspects of psychological resilience in patients with posttraumatic stress disorder (PTSD) and other psychiatric ailments. This study sought to assess the reliability and validity of the Korean version of the Connor-Davidson Resilience Scale (K-CD-RISC). METHODS: In total, 576 participants were enrolled (497 females and 79 males), including hospital nurses, university students, and firefighters. Subjects were evaluated using the K-CD-RISC, the Beck Depression Inventory (BDI), the Impact of Event Scale-Revised (IES-R), the Rosenberg Self-Esteem Scale (RSES), and the Perceived Stress Scale (PSS). Test-retest reliability and internal consistency were examined as a measure of reliability, and convergent validity and factor analysis were also performed to evaluate validity. RESULTS: Cronbach's alpha coefficient and test-retest reliability were 0.93 and 0.93, respectively. The total score on the K-CD-RISC was positively correlated with the RSES (r=0.56, p<0.01). Conversely, BDI (r=-0.46, p<0.01), PSS (r=-0.32, p<0.01), and IES-R scores (r=-0.26, p<0.01) were negatively correlated with the K-CD-RISC. The K-CD-RISC showed a five-factor structure that explained 57.2% of the variance. CONCLUSION: The K-CD-RISC showed good reliability and validity for measurement of resilience among Korean subjects.
