One of causes of compressive optic neuropathy is the sphenoid mucoceles which occur when the dranage of sinus is blocked. Mucocele of sphenoid sinus is rare, compressive to optic nerve and often misdiagnosed as pituitary tumor. We experienced a case of sphenoid sinus mucocele causing progressive visual disturbance, visual field defect, exophthalmos and headache. Plain skull and brain CT scan demonstrated sphenoid sinus mucocele. The visual acuity and visual field dramatically improved after surgery. Therefore early accurate detection and early surgical treatment are emphasized.

OBJECTIVES: This study was conducted to examine the mediating function of body weight perception (BWP) on the relationship between body mass index (BMI) and unhealthy weight control behaviors (UWCB: e.g., fasting, or taking diet pills or laxatives) and between BMI and depressed mood, and to explore the effect of distorted BWP on UWCB and depressed mood among adult women. METHODS: A regionally representative sample of 8,581 women aged 20-64 years residing in Seoul, the capital of Korea, completed the 2001 Seoul Citizens Health Indicator Survey which provides self-reported information about height, weight, BWP, UWCB, depressed mood, demographic/ socioeconomic characteristics, and health-related behaviors. Data were analyzed using bivariate and multivariate logistic regression. RESULTS: BMI was significantly associated both with UWCB and depressed mood, even controlling for all covariates. However, the magnitude and significance of each association was considerably attenuated when BWP was taken into account, indicating that BWP functioned, in part, as a mediator between BMI and UWCB and between BMI and depressed mood, respectively. Among the combinations of BMI and BWP, women who perceived themselves to be heavier than their actual BMIs appeared more likely to use UWCB, whereas women who had a distorted BWP, either underestimation or overestimation as compared with their BMIs, tended to be at greater risk for depressed mood than those who had an undistorted BWP. CONCLUSIONS: These findings suggest that how women perceive their body weight may be an important predictor and/or mediator of UWCB and depressed mood among adult Korean women.

The human telomerase reverse transcriptase (hTERT) promoter can be used for the tumor-specific expression of transgenes in order to induce selective cancer cell death. The hTERT core promoter is active in cancer cells but not in normal cells. To examine whether the combination of TNF-related apoptosis inducing ligand (TRAIL) treatment and cancer cell-selective expression of the TRAIL-death receptor could induce cell death in TRAIL-resistant cancer cells, we generated a death receptor-4 (DR4)-expressing adenovirus (Ad-hTERT-DR4), in which the expression of DR4 is driven by the hTERT promoter. Upon infection, DR4 expression was slightly increased in cancer cell lines, and cell death was observed in TRAIL-resistant cancer cell lines but not in normal human cells when DR4 infection was combined with TRAIL treatment. We also generated an adenovirus that expresses a secretable isoleucine zipper (ILZ)-fused, extracellular portion of TRAIL (Ad-ILZ-TRAIL). In cells infected with Ad-ILZ-TRAIL, TRAIL was expressed, secreted, oligomerized and biologically active in the induction of apoptosis in TRAIL-sensitive cancer cells. When Ad-hTERT-DR4 infected TRAIL-resistant HCE4 cells and Ad-ILZ-TRAIL infected TRAIL-resistant HCE7 cells were co-cultured, cell deaths were evident 24 h after co-culture. Taken together, our results reveal that the combination of TRAIL and cancer cell-specific expression of DR4 has the potential to overcome the resistance of cancer cells to TRAIL without inducing significant cell death in normal cells.

Placenta increta is an uncommon and life-threatening complication of pregnancy characterized by complete or partial absence of the decidua basalis. Placenta increta usually presents with vaginal bleeding during difficult placental removal in the third-trimester. Although placenta increta may complicate first and early secondtrimester pregnancy loss, the diagnosis can be very difficult during early pregnancy and thus the lesion is difficult to identify. We encountered with a woman who was diagnosed with placenta increta after receiving emergency hysterectomy due to intraperitoneal bleeding 2 months after an uncomplicated dilatation and curettage in the first trimester. Therefore, we report this case with a brief review of the literature.

BACKGROUND AND OBJECTIVES: Koufman described a pseudocyst of the vocal folds for the first time in 2001. A pseudocyst in all parts of the body and that is related to secretory glands is already well known, but such a lesion of the vocal folds has only been mentioned a few times. It is unclear whether or not to define a pseudocyst of the vocal folds as a benign lesion of the vocal folds. The objective of this study was to introduce the demographic and clinical findings of pseudocyst and to discuss our diagnostic and therapeutic strategies. SUBJECTS AND METHOD: We carried out a retrospective review of all the medical records, the preoperative voice lab results and the operation records from 2006 to 2009. All the patients underwent laryngomicrosurgery due to benign vocal folds lesions. We select 11 cases that showed subepithelial lesion without a definite capsule. RESULTS: Seven patients had had the history of voice abuse. One patient has been a smoker, another was an ex-smoker and the others were non-smokers. According to aerodynamic assessment, the maximum phonation time was 14.6 seconds and the mean airflow was typically increased. On laryngoscopy, all were translucent and spherical or fusiform subepithelial lesions. The preoperative stroboscopic findings showed a uniform feature of damping on the vocal fold lesion. Both the unroofing technique and the microflap technique were used. CONCLUSION: A pseudocyst would be a subepithelial lesion without a definite epithelial lining that contains serous discharge. We suggest that a pseudocyst of the vocal fold is a new benign lesion.

Purpose:
Breast conserving surgery (BCS) is generally not considered for breast cancer because of concerns about the poor prognosis of triple negative breast cancer (TNBC). We assessed the outcomes of BCS and mastectomy for patients with stage II-IIIA TNBC.
Methods:
The data of 172 breast cancer patients diagnosed with stage II-IIIA TNBC who underwent treatment at Pusan National University Hospital and Pusan National University Yangsan Hospital from 2010 to 2014 were retrospectively analyzed. The patients were divided into the following two groups: patients who underwent BCS (n=101) and those who underwent mastectomy (n=71). The Cox regression model was used to examine the outcomes of both treatments. The median follow-up period was 71 months in the BCS group, and 67 months in the mastectomy group.
Results:
The median age of the 172 patients was 51 years (range, 22-82 years). In the BCS group, radiation therapy and chemotherapy (p<0.001 and p=0.007, respectively) were performed more frequently. The BCS group had more patients with a high Ki-67 index (p=0.006), while the mastectomy group included more patients with a higher pathologic T (pT) stage (p=0.005). The 5-year loco-regional recurrence-free, disease-free, and overall survival rates of the BCS group versus the mastectomy group were 93.8% versus 95.3%, 89.8% versus 90.7%, and 90.8% versus 86.3%, respectively, but the differences were not statistically significant. Lymphovascular invasion was a risk factor for disease-free survival and advanced stage was an important risk factor for overall survival.
Conclusion
In stage II-IIIA TNBC, BCS was not inferior to mastectomy in locoregional recurrence rates, disease-free survival rates, or overall survival rates.

BACKGROUND: In order to provide essential scientific evidence on the population's health status and social health determinants as well as the current capacity of the health care system in Vietnam to health policy makers and managers, Vietnam Ministry of Health, Hanoi University of Public Health, Hanoi Medical University, and Ho Chi Minh University of Medicine and Pharmacy collaborated with Seoul National University (Korea) and conducted a health system survey in the Quoc Oai district (of Hanoi capital) that represented northern rural Vietnam. METHODS: The study design was a cross-sectional study. The survey covered different topics (more than 200 questions) and was administered in three separate questionnaires: 1) Basic information of all household members; 2) Household characteristics; and 3) Individual characteristics. Socio-demographic characteristics among the households and individuals were collected from 2,400 households sampled by multi-stage cluster sampling method: more than 200 questions. RESULTS: The household size of Quoc Oai was larger than the national average and there was no significant difference in gender composition. In addition, the proportions of pre-elderly, age 55–64, and elderly group (65 years old and over) were higher than the national population statistics. In this context, demographic transition has begun in Quoc Oai. CONCLUSION: This study design description provides the basic information about a baseline survey of a future prospective cohort (as a part of a collaborative project on strengthening the health system in Vietnam) to the prospective data user of this survey.
