OBJECTIVES: REM sleep behavior disorder (RBD) has received little attention in epidemiologic studies. This study aimed to determine the prevalence of probable REM sleep behavior disorder (pRBD) in the elderly population and its clinical features. METHODS: A random sample of 1,588 was selected from a roster of 14,050 elderly population living in Osan city. The subjects were asked to fill out the REM sleep behavior disorder screening questionnaire (RBDSQ). Subjects whose score were 5 or higher on RBDSQ underwent a diagnostic phase of person-to-person assessment by experts in RBD. RESULTS: Among 1,588 subjects, 886 elderly subjects participated in the screening phase and 123 subjects were assessed in the diagnostic phase. Eleven subjects were diagnosed as having pRBD, so prevalence was 1.5% (95% CI=0.70-2.30%). The frequency of depression and cognitive decline was significantly increased in patients with pRBD compared to subjects without pRBD, and there was no difference in sleep disturbances between two groups. CONCLUSIONS: Probable REM sleep behavior disorder is not rare in the elderly but frequently under-recognized. More attention should be paid to evaluation and treatment of RBD.

OBJECTIVES: The objective of the present study was to identify the factors that affect screening for diabetic complications by sex in the community. METHODS: This study used individual-level data from the 2013 Community Health Survey (CHS) for 20,806 (male, 9,958; female, 10,848) adults aged 30 years or older who were diagnosed with diabetes. Community-level data for 253 communities were derived from either CHS or national statistics. A chi-square test and multilevel logistic regression analysis was performed. RESULTS: There were significant differences in the rate of screening for diabetic complications according to individual-level and community-level variables. In the multilevel analysis, the community-level variance ratio of the null model was 7.4% and 9.2% for males and females, respectively. With regard to community-level variables, males were affected by the city type, number of physicians, and their living environment, while females were affected by number of physicians, natural and living environments, and public transportation. CONCLUSIONS: The factors that influenced individual willingness to undergo screening for diabetic complications differed slightly by sex; however, both males and females were more likely to undergo screening when they recognized their health status as poor or when they actively sought to manage their health conditions. Moreover, in terms of community-level variables, both males and females were affected by the number of physicians. It is essential to provide sufficient and ongoing opportunities for education on diabetes and its management through collaboration with local communities and primary care medical centers.

PURPOSE: The purpose of the present study was to assess factors associated with quality of life (QOL) and to determine whether anxiety and depression are predictive of QOL in patients with advanced gastrointestinal cancer at initial diagnosis and during the treatment process. METHODS: One hundred and twenty patients with gastrointestinal cancer requiring palliative chemotherapy were enrolled. RESULTS: At baseline, depression, performance status, and anxiety accounted for 55.0% (p<.001) of the variance in global health status score, depression accounted for 22.0% (p<.001) of the variance in functional scales score, and anxiety accounted for 19.0% (p<.001) of the variance in symptom scales score. At 3 months, depression, pain, and performance status accounted for 72.0% (p<.001) of the variance in global health status score, 76.0% (p<.001) of the variance in functional scales score, and 74.0% (p<.001) of the variance in symptom scales score. CONCLUSION: Anxiety and depression were significant predictive factors of QOL in patients with advanced gastrointestinal cancer. Depression and performance status were significant predictive factors of QOL at both baseline and 3 months, and anxiety and pain were significant predictive factors of QOL at baseline and 3 months, respectively.

BACKGROUND: Despite an increased incidence of endometrial carcinomas in young Korean women, clinicopathologic characteristics and treatment outcomes have not been analyzed. METHODS: We investigated clinicopathologic characteristics of endometrial carcinoma in 48 women who were under the age of 40 in order to determine treatment guideline. RESULTS: According To The Criteria Of The Korean Society For Obesity, 70.8% Of Study Patients Were Overweight Or Obese, With An Average Body Mass Index (Bmi) Of 26.0 kg/m2. Twelve Patients Received Progesterone Treatment Only, And 6 Of Them Later Had Successful Pregnancies. The Histologic Subtype Was Endometrioid Adenocarcinoma In All Patients. Figo Stages Were 1A(41.7%), 1B(47.1%), II (2.8%), IIB2.8%), IIIA(2.8%), And IIIC (2.8%). Figo Grades Were Grade 1 (79%) Or 2 (21%). The Average Depth Of Invasion, Excluding Stage 1a, Was 4.6 Mm In The Hysterectomy Specimens. Two Patients Were Given Post-operative Radiation Treatment And 4 Were Treated With Chemotherapy. All But One Case Had An Uneventful Postoperative Course During Follow-up. CONCLUSIONS: A majority of endometrial carcinomas in young Korean women were associated with an early FIGO stage, favorable histologic subtype and grades, and a good prognosis. Progesterone treatment with close observation was a successful treatment option in a selected group of young patients.

Background: This study explored the effect of anger on suicidality by dividing participants into a group with major depressive disorder (MDD) and a non-MDD group, and also investigated whether the anger expression affects suicidality in participants without clinical depression. Methods: A total of 1,015 residents responded to anonymous questionnaires in our survey. The survey included scales, such as the Patients Health Questionnaire-9 (PHQ-9), Korean State-Trait Anger Expression Inventory, and Mini-International Neuropsychiatric Interview-Plus. Participants were categorized into the MDD and non-MDD groups or depression group and non-depression group following the PHQ-9 score. Logistic regression analysis was performed to confirm the association between anger and suicidality in the non-MDD and non-MDD groups. Results: Anger suppression and higher PHQ-9 appeared as risk factors for suicidality in the non-MDD group. The depression level in the non-MDD group mediates the relationship between anger suppression and suicidality. Higher PHQ-9 was no longer a risk factor and anger suppression remains a risk factor in the non-depression group. Conclusion Not only depression evaluation, but also anger evaluation is important when assessing suicidality. Implementing anger management programs for people with high anger suppression can help lower suicidality in Korean society, where negative emotional expression is suppressed.

OBJECTIVE: The structural alteration of brain shown in patients with alcohol use disorder (AUD) can originate from both alcohol effects and genetic or developmental processes. We compared surface-based parameters of patients with AUD with healthy controls to prove the applicability of surface-based morphometry with head size correction and to determine the areas that were sensitive to brain alteration related to AUD. METHODS: Twenty-six abstinent male patients with AUD (alcohol group, mean abstinence=13.2 months) and twenty-eight age-matched healthy participants (control group) were recruited from an inpatient mental hospital and community. All participants underwent a 3T MRI scan. Surface-based parameters were determined by using FreeSurfer. RESULTS: Every surface-based parameter of the alcohol group was lower than the corresponding control group parameter. There were large group differences in the whole brain, grey and white matter volume, and the differences were more prominent after head size correction. Significant group differences were shown in cortical thicknesses in entire brain regions, especially in parietal, temporal and frontal areas. There were no significant group differences in surface areas, but group difference trends in surface areas of the frontal and parietal cortices were shown after head size correction. CONCLUSION: Most of the surface-based parameters in alcohol group were altered because of incomplete recovery from chronic alcohol exposure and possibly genetic or developmental factors underlying the risk of AUD. Surface-based morphometry with controlling for head size is useful in comparing the volumetric parameters and the surface area to a lesser extent in alcohol-related brain alteration.

OBJECTIVE: We determined whether aldehyde dehydrogenase 2 (ALDH2) activity alters the way in which drinking behaviors are affected by gene polymorphisms of other alcohol-metabolizing enzymes and serotonin-related proteins. METHODS: Through a follow-up survey with a cohort comprising 551 university freshmen over a period of 6 years, we examined the genetic factors affecting drinking behaviors. In 2000, drinking behaviors were assessed and tryptophan hydroxylase (TPH) and ALDH2 gene polymorphisms were determined. Drinking behaviors were repeated in 2006 (n=150), and the gene polymorphisms of ADH1B, ADH1C, CYP2E1, 5-HTR2A 1438A/G, and 5-HTR2A IVS2 were also determined. RESULTS: In 2000, the variant and wild-type ALDH2 groups exhibited little difference in terms of drinking frequency and problem drinking. Furthermore, some genotypes influenced only the variant group: ADH1B*2/*2 was associated with a lower drinking frequency, and CYP2E1 c2 allele was associated with an increased risk of problem drinking. In 2006, drinking frequency and risk of problem drinking were significantly lower in the variant group than in the wild-type group. However, the TPH AA genotype disturbed that difference, meaning that the subjects in the variant group had developed a similar level of risk of problem drinking to that in the wild-type group. CONCLUSION: Korean university freshmen who were identified as a variant group drank as frequently as those in the wild-type group. For the subsequent 6 years they drank less frequently, thus decreasing the risk of problem drinking. However, that frequency drop was interrupted in those with gene polymorphisms such as ADH1B*1, CYP2E1 c2, and TPH A.

BACKGROUND: Primary splenic vascular lesions include the tumor and the inflammatory condition. A primary splenic vascular tumor is rare but is the most common tumor of the benign primary splenic tumors. METHODS: We describe the clinicopathological, radiological, and immunophenotypical findings of 40 cases of primary vascular lesions identified at our hospital from 1996 to 2009. RESULTS: The patients included 18 men and 22 women, aged 12 to 74 years, with a mean of 43.3-years and median of 40-years. They comprised 14 hemangiomas (35%), 13 lymphangiomas (32.5%), three hamartomas (7.5%), three littoral cell angiomas (7.5%), three sclerosing angiomatoid nodular transformations (SANT, 7.5%) and four angiosarcomas (10%). The majority of the patients (65%) were asymptomatic. Some of the patients (32.5%) complained of abdominal pain, and 2.5% of the patients presented with fever. Metastases were identified in 75% of the patients with an angiosarcoma at the initial work-up. One angiosarcoma patient died of the disease despite adjuvant chemoradiotherapy. The radiological findings for hamartoma, littoral cell angioma, and SANT were nonspecific. Microscopically, six types of vascular lesions showed classic morphological and immunophenotypical features of their type. CONCLUSIONS: One should be aware of rare splenic vascular lesions when radiological findings are nonspecific. Histomorphological and immunophenotypical features are helpful for the differential diagnosis.

Desmoplastic melanoma (DM) is a rare malignant melanoma variant. Although DM mainly affects the skin chronically exposed to the sun, a small number of mucosal DM have been reported. Primary mucosal DM is difficult to diagnose because of its rarity and atypical histopathologic features. Here, we report a case of DM in a 52 year-old female who presented with a right cervical mass and upper gingival pigmentation. A CT scan revealed an ill-defined infiltrative mass 2 cm in size under the pigmented mucosa. She subsequently underwent a partial maxillectomy with neck dissection. Gross examination revealed that the mass exhibited a grayish white fibrotic cut surface and that the maxillary bone had been destroyed. Microscopically, the main mass was composed of cigar-shaped or wavy spindle cells with desmoplastic stroma under the melanoma in situ. The diagnosis of DM was confirmed immunohistochemically with S100 protein positivity and HMB45 negativity. The patient has survived for 29 months after the operation with a presumed metastatic focus.

OBJECTIVES: The purpose of this study was to investigate the differences between adolescents and adults, in the perspective-taking ability, as well as the brain activation patterns during the perspective-taking situation.METHODS: We recruited healthy adolescents aged 13 years to 15 years (n = 20) and adults aged 19 years to 29 years (n = 20). All the subjects were scanned while performing the perspective-taking task, in which an emotional situation was presented in the form of statements comprising first person, as well as third person perspectives. Differences in brain activation between groups were assessed by contrasting neural activity during the tasks.RESULTS: In the between-group analysis, while performing the third-person perspective-taking task, the adolescent group showed greater neural activities in the middle frontal gyrus and precentral gyrus as compared to the adult group. Positive correlation was observed between the activity in the frontal areas (Brodmann area 6/9) and the score of scales related to perspective-taking and social cognition in the adolescent group.CONCLUSIONS: This study suggests that several frontal brain areas of adolescents needs to be overactivated in order to compensate for low perspective-taking ability when they ought to take another person's point of view.
