PURPOSE: Neuroendocrine (NE) cells of the prostate are considered to be involved in the pathogenesis of benign prostate hyperplasia (BPH). By a comparative analysis of NE cell density in BPH tissue of men who were either exposed to or not exposed to 5alpha-reductase inhibitor, we investigated the relationship between NE cells and BPH, and the effect of androgen deprivation on NE cells. MATERIALS AND METHODS: Prostate tissue specimens, obtained from 30 men by transurethral resection of the prostate or radical cystoprostatectomy, were used. Of the 30 patients, 10 had a prostate smaller than 25 ml (normal control), the other 20 had a prostate larger than 40ml, 10 of who had taken 5alpha-reductase inhibitor (finasteride) for 3 months before surgery (androgen blockade group), and 10 who had not (BPH group). The distribution of NE cells in the prostate was examined using the anti-chromogranin A (CgA) antibody, and the density of the CgA-positive cells was compared by an optical dissector method. Immunoblotting was performed using the neuron specific enolase (NSE) antibody. A Mann-Whitney U test was used in a statistical analysis. RESULTS: Most of the CgA-positive NE cells were localized between the acinar epithelial cells. The mean numbers of CgA-positive NE cells per acinus in the normal controls and the BPH groups were 1.67+/-0.78 and 4.45+/-2.54, respectively, and the difference was statistically significant (p<0.05). However, the mean number of CgA-positive NE cells in the androgen blockade group, was 4.93+/-2.17, which was similar to the BPH group. In a NSE immunoblotting study, a distinct band was observed in the BPH and androgen blockade groups, but the density of the band was higher in the androgen blockade group. CONCLUSIONS: Our results suggest that NE cells may be involved in the hyperplastic process of BPH. Inhibition of dihydrotestosterone, caused by the oral administration of the 5alpha-reductase inhibitor, failed to induce any significant change in the NE cells, probably due to the incomplete androgen blockade.

PURPOSE: The aim of this study was to examine the health-related behaviors related to a family history of cancer (FHCA) among Korean women underwent cancer screening. MATERIALS AND METHODS: A total of 8,956 women who underwent cancer screenings during 2001-2011 at the National Cancer Center, Korea, were analyzed. The association between health-related behaviors and a FHCA were assessed using multivariate logistic regression. RESULTS: Compared to women with no FHCA, women with FHCA were more likely to smoke (adjusted odds ratio [aOR], 1.32; 95% confidence interval [CI], 1.06 to 1.65), to be exposed to passive smoking (aOR, 1.21; 95% CI, 1.15 to 1.65), and less likely to engage in regular exercise (aOR, 1.20; 95% CI, 1.01 to 1.41). Combined effects of selected health behaviors for FHCA were significant, although no statistically significant interactions were observed between selected health behaviors. Compared to women with no FHCA, women with FHCA were more likely to simultaneously smoke and be exposed to passive smoking (aOR, 1.65; 95% CI, 1.17 to 2.31) and to simultaneously smoke and be physically inactive (aOR, 1.62; 95% CI, 1.00 to 2.64). CONCLUSION: The study found that women with a FHCA exhibited unhealthy behaviors compared to women without FHCA. Higher emphasis on lifestyle modifications using a new standardized tool is strongly recommended for those with a FHCA, as well as individuals who are at high risk, together with their family members.

PURPOSE: The purpose of this study is to explore and understanding the nature of the shift workers' experience in industries requiring 24 hours-a-day service provision and support. For the purpose, the present researcher made a research question, "What are workers' experience in the shift work?" METHODS: In the study, 5 male shift workers, 3 female shift worker and a woman (key informant) whose husband is a shift worker participated. Then profound interviews with the participants were made after their agreement. RESULTS: The researcher classified the significant statements under 6 theme clusters, 1) sense of difference; 2) worries about health; 3) draining of emotion; 4) anxiety; 5) sadness; and 6) being comfortable. CONCLUSIONS: Shift work which is inevitable in modern society may have severe influences on shift workers' physical, mental and psychological aspects by causing their work cycle rhythm to be unbalanced. Finally, the researcher hopes that the results of the study would help understand workers' life and increase social concern and support to the workers.

Purpose:
To investigate the biometric characteristics of eyes with pseudoexfoliation syndrome (PEX) according to the anterior chamber depth (ACD) by comparing them to patients with acute angle closure (AAC) and a control group.
Methods:
A total of 130 eyes of 121 subjects (PEX, 49 eyes; AAC, 28 eyes; and control, 53 eyes) were included in the study. Axial length (AL), ACD, and lens thickness (LT) were measured with an IOL Master® 700 (Carl Zeiss Meditec, Jena, Germany). The total PEX (PXall) group was divided into a PEX with deep ACD group (PXd) and a shallow ACD group (PXs) based on an ACD of 2.70 mm. We compared the biometric results among the PXall, PXd, PXs, AAC, and control groups.
Results:
There was no significant difference in AL between the PXall and control groups; however, the PXall group had a shallower ACD and thicker lenses. After dividing the PXall group into two groups based on ACD, the PXd group showed no difference in LT compared to the control group (p = 0.113). The LT of the PXs group was thicker than those of the PXd and control groups (p < 0.001 and p < 0.001, respectively). The PXs group had longer ALs than the AAC group (p = 0.025); however, there was no difference in LT or in the ratio of LT to AL (p = 0.222 and p = 0.076, respectively).
Conclusions
The biometric characteristics were different in eyes with PEX based on ACD. PEX patients with deep ACDs showed no difference in biometry compared to the control group; however, PEX patients with shallow ACDs showed characteristics of a thick LT, similar to AAC patients. There was no difference in the ratio of LT to AL among groups.

Obesity may be the consequence of various environmental or genetic factors, which may be highly correlated with each other. We aimed to examine whether grandmaternal and maternal obesity and environmental risk factors are related to obesity in daughters. Daughters (n = 182) recruited from female students, their mothers (n = 147) and their grandmothers (n = 67) were included in this study. Multivariable logistic regression was used to analyze the association between the daughter's obesity and maternal, grandmaternal, and environmental factors. Maternal heights of 161-175cm (OD: 8.48, 95% CI: 3.61-19.93) and 156-160 cm (2.37, 1.14-4.91) showed positive associations with a higher height of daughter, compared to those of 149-155 cm. Mothers receiving a university or a higher education had a significant OR (3.82, 1.27-11.50) for a higher height of daughter compared to those having a low education (elementary school). Mother having the heaviest weight at current time (59-80 kg, 3.78, 1.73-8.28) and the heaviest weight at 20 years of age (51-65 kg, 3.17, 1.53-6.55) had significant associations with a higher height of daughters, compared to those having the lightest weight at the same times. There was no association between the height, weight, and BMI of daughters and the characteristics and education of her grandmothers. In conclusion, although genetic factors appear to influence the daughter's height more than environmental factors, the daughter's weight appears to be more strongly associated with individual factors than the genetic factors.

A 36-year-old female patient with aplastic anemia developed massive hemoptysis and was placed on ventilator support. However, airway obstruction by blood clots triggered desaturation and ventilator malfunction. Manual ventilation was initiated to improve oxy-genation, and emergency flexible bronchoscopy was performed to clear the airway. Nevertheless, the patient developed extensive subcutaneous emphysema, pneumothorax, and pneumomediastinum.

OBJECTIVE: After classifing the twin-twin transfusion syndrome (TTTS) according to clinical stage by Quintero, we reviewed effectiveness and usefulness of clinical stage by Quintero in diagnosis and treatment of TTTS. METHODS: Twelve cases (16%) were diagnosed as TTTS among 75 examples (31.3%) of monochorionic twin pregnancy out of 240 cases of twin pregnancy born in our hospital between Mach 2000 and June 2004. For TTTS, the clinical stage was decided at the time of initial diagnosis, and any changes of it were observed according to the developments of pregnancy. Neonate was regarded as alive when 5 minutes Apgar score was above 7 after birth. Also we observed the vascular anastomosis of placenta, and classified the method of treatments and its results according to each clinical stage. RESULTS: Two cases were classified into the clinical stage 1 through 4 each, and 4 cases in the clinical stage 5. The higher the clinical stage, the shorter the duration between diagnosis and delivery (p<0.05). In cases of both survivors, compared to no survivors, the interval between diagnosis and delivery were long (p<0.05). In the clinical stage 4 and 5, we found many cases that didn't have placental vascular anastomosis between artery and artery, and in this case, there revealed poor perinatal outcomes. For 4 cases that fell in the clinical stage 1 and 2 and 4, we performed amnioreduction and for one case in the clinical stage 2, we did amnioseptostomy at the same time. In 4 cases with amnioreduction or amnioseptostomy, survival rate was 38%. CONCLUSION: The clinical classification system of TTTS by ultrasound would be helpful for planning treatments and also for predicting the outcomes.

Leptomeningeal carcinomatosis, an important and serious neurological complication of malignant cancers, is asso- ciated with severe disability and high mortality. It is most commonly seen in patients with breast cancer, lung cancer and malignant melanoma. However, leptomeningeal carcinomatosis induced by gastric cancer has been rarely reported, although gastric cancer is one of the most common causes of cancer-related deaths in Korea. We report a case of a 76- year-old woman with leptomeningeal carcinomatosis presenting as a neurological complication of gastric cancer and con- firmed by cytology examination of the cerebrospinal fluid and brain magnetic resonance imaging with gadolinium enhan-cement.

PURPOSE: Enhancer of zeste homolog 2 (EZH2), a kind of transcriptional repressor, is reportedly over-expressed in metastatic prostate cancer. In this study, we analyzed EZH2 mRNA in circulating tumor cells (CTCs) in peripheral blood as a biomarker in patients with metastatic prostate cancer. PATIENTS AND METHODS: Ber-EP4 coated immunomagnetic beads were used to harvest CTCs, and mRNA was isolated by oligo- dT conjugated immunomagnetic beads. Reverse transcriptase- polymerase chain reaction for EZH2 mRNA was performed and the expression density was measured. The sensitivity of this test for detection of EZH2 mRNA was determined by serial dilutions of a human prostate cancer cell line. Blood samples were collected from 20 patients each with metastatic or localized prostate cancer and 10 healthy volunteers. RESULTS: Sensitivity experiments showed that the test was highly sensitive as it could detect 10 tumor cells per 5mL. EZH2 mRNA expression was obtained from peripheral blood samples of patients and control subjects. EZH2 mRNA expression density in the metastatic prostate cancer group was significantly higher than in the control (p=0.023) and localized prostate cancer groups (p=0.019). There was no difference between the control and localized prostate cancer groups (p > 0.05). CONCLUSION: EZH2 mRNA expression in circulating epithelial cells represents a promising marker for detecting early metastasis in prostate cancer. However, more specific and sensitive techniques for detection of CTCs are needed to avoid mononuclear cell contamination.
