OBJECTIVES: Breast cancer has been the most prevalent female cancer in South Korea since 2001. Early detection of this disease is the most effective strategy for reducing mortality. The objective of this study was to identify factors which could predict advanced stage at diagnosis of breast cancer. METHODS: Participants who were initially diagnosed with breast cancer and referred to the Stress Clinic of the Breast Cancer Center at Kyungpook National University Hospital were included. Through a semi-structured interview, the authors investigated psychosocial variables such as the extent of marital and family functioning and emotional-economic family burden as well as sociodemographic and health behavior-, health characteristic- and cancer-related variables. RESULTS: Data were collected from 219 participants. One hundred and twenty(54.8%) subjects were diagnosed with advanced-stage breast cancer. Variables that were significantly different between the advanced-stage and early-stage groups included : monthly breast self examination(p<0.000), annual mammographic screening(p< 0.000), mode of tumor detection(p<0.000), nature of the first symptoms(p<0.000), time to treatment after di-agnosis(p<0.000), overloaded economic and family burden(p=0.018), marital functioning(p<0.000) and family functioning(p<0.00). Logistic regression analysis indicated that irregular annual mammography screening(OR=7.431 ; 95% CI 2.407-22.944) or a lack of screening(OR=25.299 ; 95% CI 7.855-81.482) and a dysfunctional marital relationship(OR=4.772 ; 95% CI 2.244-10.145) were significantly associated with advanced stage at diagnosis of breast cancer. CONCLUSIONS: We reconfirmed screening behavior to be a risk factor for delayed diagnosis of breast cancer. Our findings also emphasized the importance of psychosocial factors such as marital functioning in early detection of breast cancer. Psychiatric consultation in the area of martial functioning could be beneficial for increasing early detection in breast cancer.

PURPOSE: To evaluate the effect of light-curing on the immediate and delayed micro-shear bond strength (microSBS) between yttria-tetragonal zirconia polycrystal (Y-TZP) ceramics and RelyX Ultimate when using Single Bond Universal (SBU). MATERIALS AND METHODS: Y-TZP ceramic specimens were ground with #600-grit SiC paper. SBU was applied and RelyX Ultimate was mixed and placed on the Y-TZP surface. The specimens were divided into three groups depending on whether light curing was done after adhesive (SBU) and resin cement application: uncured after adhesive and uncured after resin cement application (UU); uncured after adhesive, but light cured after resin cement (UC); and light cured after adhesive and light cured resin cement (CC). The three groups were further divided depending on the timing of microSBS testing: immediate at 24 hours (UUI, UCI, CCI) and delayed at 4 weeks (UUD, UCD, CCD). microSBS was statistically analyzed using one-way ANOVA and Student-Newman-Keuls multiple comparison test (P<0.05). The surface of the fractured Y-TZP specimens was analyzed under a scanning electron microscope (SEM). RESULT: At 24 hours, microSBS of UUI group (8.60+/-2.06 MPa) was significantly lower than UCI group (25.71+/-4.48 MPa) and CCI group (29.54+/-3.62 MPa) (P<0.05). There was not any significant difference between UCI and CCI group (P>0.05). At 4 weeks, microSBS of UUD group (24.43+/-2.88 MPa) had significantly increased over time compared to UUI group (P<0.05). The SEM results showed mixed failure in UCI and CCI group, while UUI group showed adhesive failure. CONCLUSION: Light-curing of universal adhesive before or after application of RelyX Ultimate resin cement significantly improved the immediate microSBS of resin cement to air-abrasion treated Y-TZP surface. After 4 weeks, the delayed microSBS of the non-light curing group significantly improved to the level of light-cured groups.

OBJECTIVE: To identify attachment insecurity as an associative factor with unresolved psychological distress 1 year after surgery in the early breast cancer (BC) population. METHODS: One-hundred fourteen participants completed the Hospital Anxiety and Depression Scale (HADS) and the Experiences in Close Relationship (ECR-M36) questionnaire within 1 week (baseline) and at 1-year post-surgery (follow-up). Participants were categorized into the distress and the non-distress groups based on a HADS-total score cut-off of 15. Logistic regression analysis revealed predictive factors of distress at follow-up. RESULTS: At baseline, 53 (46.5%) participants were found to be in the distress group. The degree of distress decreased over 1 year (p= 0.003); however, 43 (37.7%) showed significant remaining distress at follow-up. Baseline scores of the ECR-M36 avoidance [odds ratio (OR)=1.045, 95% confidence interval (CI)=1.002–1.090] and HADS-total (OR=1.138, 95% CI=1.043–1.241) were predictors of distress at follow-up. CONCLUSION: A substantial proportion of early BC patients suffer distress even one-year after surgery. Avoidant attachment appeared to be an influential factor on distress in early BC patients. Moreover, the finding that initial distress level could predict one at 1-year post-operation warrant a screening and management of distress along with BC treatment.

OBJECTIVE: The Young Schema Questionnaire (YSQ) is a self-report measure of early maladaptive schemas and is currently in its third revision; it is available in both long (YSQ-L3) and short (YSQ-S3) forms. The goal of this study was to develop a Korean version of the YSQ-S3 and establish its psychometric properties in a Korean sample. METHODS: A total of 542 graduate medical students completed the Korean version of the YSQ-S3 and several other psychological scales. A subsample of 308 subjects completed the Korean YSQ-S3 both before and after a 2-year test-retest interval. Correlation, regression, and confirmatory factor analyses were performed on the data. RESULTS: The internal consistency of the 90-item Korean YSQ-S3 was 0.97 and that of each schema was acceptable, with Cronbach's alphas ranging from 0.59 to 0.90. The test-retest reliability ranged from 0.46 to 0.65. Every schema showed robust positive correlations with most psychological measures. The confirmatory factor analysis for the 18-factor structure originally proposed by Young, Klosko, and Weishaar (2003) showed that most goodness-of-fit statistics were indicative of a satisfactory fit. CONCLUSION: These findings support the reliability and validity of the Korean version of the YSQ-S3.

OBJECTIVE: This study was carried out to help the comprehensive rehabilitation of cervical cord injuries by measuring propulsion force and endurance on their wheelchair hand- rims, predicting the differences between neurological levels and analysing the factors which contributed to maintain the wheelchair propulsion force. METHOD: The BTE work simulator was used on 17 cervical cord injuries to test the force and endurance during wheel chair propulsion. The 141 large wheel of BTE work simulator and standard wheelchair which was removed handrims was used for simulating wheelchair propulsion. Wilcoxon rank sum test was used to compare force and endurance among the groups. RESULTS: The wheelchair propulsion force and endurance showed significant differences between neurological levels and types of the life style. The lower the level, the higher the strength and endurance (p<0.001). The wheelchair propulsion force of cervical cord injuries showed statistically significant differences between those with and without jobs (p<0.05). The outdoor wheelchair users and wheelchair propulsion exercise group showed significantly high maximum isometric strengths compared to the indoor users and the only ROM exercise group, respectively (p<0.05). CONCLUSION: During the rehabilitation period cervical cord injured persons need the wheelchair propulsion exercise using BTE work simulator to improve the quality of life.

Pain control is very important in managing terminal cancer patients and there are several modalities to alleviate their pain. A high dosage of epidural morphine is effective to control terminal cancer pain. Furthermore, to decrease the amount of morphine, adding an alternative adjuvant like ketamine to the morphine regimen is considered helpful for controlling the pain of a terminal cancer patient. A 45 year old male patient with terminal lung cancer had neck pain that was caused by multiple bone metastases. Continuous epidural block was started with 2 mg/day of morphine and the dosage was gradually increased to 90 mg/day in 86 days. 30 mg/day of ketamine was then added to it. Overall, the morphine and ketamine dosages were increased to 564 mg/day and 140 mg/day, respectively, in 11 months until the patient expired. In this case, the high dosage of epidural morphine, 580 mg/day, was administered to control cancer pain without any severe adverse effects.
