This study was undertaken to evaluate the prevalence of underlying significant lesions among women referred for colposcopy after atypical glandular cell (AGC) smears and the associated risks. The present study reviewed data from women with AGC smears undergoing colposcopy at the Colposcopy Clinic, Faculty of Medicine, Khon Kaen University, Thailand between January 2001 to December 2014. Significant lesions included cervical intraepithelial neoplasia grade 2-3, adenocarcinoma in situ, endometrial hyperplasia, and cancer. During the study period, 170 women with AGC cytology were reviewed. The mean age was 45.7 years. Thirty-eight women (22.4%) were postmenopausal. Eighteen smears (10.6%) were further subclassified as AGC-favor neoplasia (AGC-FN). In total, significant lesions were noted in 27 women (15.9%; 95%CI, 7.8%-18.3%). Thirteen women (7.6%, 95%CI, 4.1%-12.7%) were found to have cervical cancer or endometrial cancer. Two variables were independently associated with an increased risk of significant histopathology results: level of educational attainment (secondary level or lower versus bachelor degree or higher) and types of AGC (AGC versus AGC-FN). Women who had low level of education and those with AGC-FN were at the higher risk of significant lesions (OR, 3.16; 95%CI 1.10-9.11 and OR, 4.62; 95%CI, 1.54-13.85, respectively). In conclusion, the rate of significant lesions among women referred for colposcopy after AGC smears is considerably high. Low education and smear subtypes appear independently associated with a higher risk of significant lesions.

Background: Mouse mammary tumor virus (MMTV) is the major cause of mammary tumors in mice. There is limited controversial evidence about the probable etiologic role of MMTV- like virus in human breast cancer. Materials and Methods: A total of 40 Formalin fixed paraffin embedded samples with diagnosis of breast cancer were collected in a period of 3 years from cancer institute of Iran. We selected both pre-menopausal and post-menopausal patients with different histologic grades and different ethnic groups. We evaluated presence of MMTV-like virus env gene through real time PCR method. Results: Forty patients (20 pre and 20 postmenopausal women) were evaluated with the mean age of 49.67. The average tumor size was 39 mm. None of the studied samples were positive for MMTV-like virus env gene target sequences. Conclusions: We found no evidence on the potential role of MMTV-like virus in the carcinogenicity of breast cancer among Iranian women.

Osteoporosis is a major health problem in countries with aging populations, resulting in excess morbidity and mortality. This study was conducted to investigate knowledge and practices about osteoporosis in adults and to identify some factors which were influenced to that. 56-item questionnaire was developed including five domains(general characteristics, osteoporosis-related characteristics, knowledge of risk factors, knowledge of prevetion and practices). Subjects of this study were 368 adult ranged from 30 to 59. Data were collected during the period from June 15 to July 10, 1998 by means of a structured questionnare. The data were analyzed using descriptive statistics, t-test, ANOVA, Post Hoc, Pearson Correlation by SPSSWIN program. The results were as follows: 1. The mean knowledge score of risk factors for osteoporosis was 7.46(full score=15) and that of prevention of osteoporosis was 8,79(full score=12). 2. The mean practice score of osteoporosis was slightly higher than median value. 3. Women had better knowledge about osteoporosis risk factors and practiced more osteoporosis-prevention measures than men. Although the data demonstrated fairly good general knowledge about osteoporosis in the subjects, the older group(age 50-59), those at the highest risk of developing the disease, knew less about osteoporosis than the younger group(age 30-39) did. 4. The persons who had heard about osteoporosis and bone mineral density though mass media medical pratitioners and who didn't take any medicine for osteoporosis had better knowledge about osteoporosis and preventive measures. The practice score was significantly higer in the postmenopausal women and persons who were already diagnosed as osteoporosis patients, or who underwent bone mineral density measurements. 5. The relation between knowledge and practice was significant. In conclusion, there was a modest degree of general knowledge about osteoporosis and its consequences in adults. Further randomized studies are needed to evaluate the relationship between osteoporosis and risk factors. However, these results support the importance of education to prevent osteoporosis.

The aim of this investigation was to examine the effects of osteocalcin, bone-specific alkaline phophatase, estrogen, insulin-like growth factor-I (IGF-I), Ca, P and bone mineral density on osteoporosis induced by ovariectomy in rats. Female Sprague-Dawley 30 rats of three-forth's birth, weighing $215{\pm}10g$, were divided into two groups including the sham operation group(5 heads) and ovariectomy group(25 heads). They were fed normal diets for 2 weeks before the experimental operation and for 8 more weeks after operation. The level of osteocalcin, TALP, BALP, estrogen, bone mineral density and IGF-I were increased in experimental group, but a little increased in sham operation group at same period. The change of rates of osteocalcin, TALP, BALP, estrogen, bone mineral density and IGF-I were significantly higher in experimental group than sham operation group. $Ca^{2+}$ was not changed between two groups and P was significantly decreased in experimental group and Ca/P ratio was higher in experimental group than sham operation group. Body weights were increased in all two groups and growth rate per day was higher in experimental group than sham operation group. However, femur weight I body weight ratio was lower in experimental group than sham operation group.

Background: Water pressure and muscle contraction may influence bone mineral density (BMD) in a positive way. However, divers experience weightlessness, which has a negative effect on BMD. The present study investigated BMD difference in normal controls and woman free-divers with vertebral fracture and with no fracture. Methods: Between January 2010 and December 2014, traditional woman divers (known as Haenyeo in Korean), and non-diving women were investigated. The study population was divided into osteoporotic vertebral fracture and non-fracture groups. The BMD of the lumbar spine and femoral neck was measured. The radiological parameters for global spinal sagittal balance were measured. Results: Thirty free-diving women and thirty-three non-diving women were enrolled in this study. The mean age of the divers was $72.1{\pm}4.7$ years and that of the controls was $72.7{\pm}4.0$ years (P = 0.61). There was no statistical difference in BMD between the divers and controls. In divers, cervical lordosis and pelvic tilt were significantly increased in the fracture subgroup compared to the non-fracture subgroup (P = 0.028 and P = 0.008, respectively). Sagittal vertical axis was statistically significantly correlated with cervical lordosis (Spearman's rho R = 0.41, P = 0.03), and pelvic tilt (Spearman's rho R = 0.46, P = 0.01) in divers. Conclusion: BMD did not differ significantly between divers and controls during their postmenopausal period. When osteoporotic spinal fractures develop, compensation mechanisms, such as increased cervical lordosis and pelvic tilt, was more evident in traditional woman divers. This may be due to the superior back muscle strength and spinal mobility of this group of women.

This study was carried out to identify the Important modifiable risk factors for reduced bone mass and to construct prediction model which can classify women with either low or high bone mass. Through the literature review, individual characteristics such as age, body weight, height, education level, family history, age of menarche, postmenopausal period, gravity, parity, menopausal status, and breast feeding period were identified and factors of life style such as past milk consumption, past physical activity, present daily activity, present calcium intake, alcohol intake, cigarette smoking, coffee consumption were identified as influencing factors of reduced bone mass in women. Four hundred and eighty women aged between 28 and 76 who had given measurement bone mineral density by dual energy x-ray absortiometry in lumbar vertebrae and femur from July to October, 1997 at 4 general hospitals in Seoul and Pusan were selected for this study. Women were excluded if they had a history of any chronic illness such as rheumatoid arthritis, diabetes mellitus, hyperthroidism, & gastrointestinal disorder and any medication such as calcium supplements, calcitonin, estrogen, thyroxine, antacids, & corticosteroids known affect bone. As a result of these exclusion criteria, four hundred and seventeen women were used for analysis. Multiple logistic regression model was developed for estimating the likelihood of the presence or absence of reduced bone mass. A SAS procedure was used to estimate risk factor coefficient. The results are as follows For lumbar spine, the variables significant were age, body weight, menopause status, daily activity, past milk consumption, and past physical activity(p<0.01), while for femoral Ward's triangle, age, body weight, level of education, past milk consumption, past physical activity(p<0.001). Past physical activity, present daily activity and past milk consumption are the most powerful modifiable predictors in vertebrae and femur among the predictors. When the model performance was evaluated by comparing the observed outcome with predicted outcome, the model correctly identified 74.1% of persons with reduced bone mass and 84.5% of persons with normal bone mass in the lumbar vertebrae and 82.9% of persons with reduced bone mass and 75.0% of persons with normal bone mass in the femoral Ward's triangle. On the basis of these results, a number of recommendations for the management of reduced bone mass may be made : First, those woman who are classified as high risk group of the reduced bone mass in the prediction model should examine the bone mineral density to further examine the usefulness of this model. Second, the optimal amount of milk consumption and a regular weight bearing exercise in childhood, adolescence, and early adult should be ensured.

The antiestrogen tamoxifen is currently the most commonly used adjuvant treatment of breast cancer with antiestrogenic effect on mammary tissue. However, it is also associated with endometrial abnormalities, including hyperplasia, polyps, carcinoma, mostly interpreted as evidence of estrogenic effect on the endometrium. Previously, tamoxifen-associated polyp in breast cancer has been reported in the literature. Most studies had a long follow-up period and tamoxifen-associated polyp developed more than 1 year after tamoxifen treatment. In this case, we report an unusual case of rapid growing and multiple endometrial polyps that were developed only after 3 months' tamoxifen treatment in a postmenopausal breast cancer patient who received quadrant mastectomy with a brief review of literature.

Objective: The aim of this study was to evaluate predictive role of risk of malignancy index in discriminating between benign and malignant adnexal masses preoperatively. Methods: This retrospective study was conducted with a total of 569 patients with adnexal masses/ovarian cysts managed surgically at our clinic between January 2006 and January 2012. Obtained data from patient files were age, gravidity, parity, menopause status, ultrasound findings and CA125 levels. For all patients ultrasound scans were performed. For the assessment of risk of malignancy index (RMI) Jacobs' model was used. Histopathologic results of all patients were recorded postoperatively. Malignancy status of the surgically removed adnexal mass was the gold standard. Results: Of the total masses, 245 (43.1%) were malignant, 316 (55.5%) were benign and 8 (1.4%) were borderline. The mean age of benign cases was lower than malign cases ($35.2{\pm}10.9$ versus $50.8{\pm}13.4$, p<0.001). Four hundred and five of them (71.2%) were in premenopausal period. Malignant tumors were more frequent in postmenopausal women (81% versus 29%, p<0.001). All ultrasound parameters of RMI were statistically significantly favorable for malignant masses. In our study ROC curve analysis for RMI provided maximum Youden index at level of 163.85. When we based on cutoff level for RMI as 163.85 sensitivity, specificity, PPV, NPV was calculated 74.7%, 96.2%, 94% and 82.6%, respectively. Conclusions: RMI was found to be a significant marker in preoperative evaluation and management of patients with an adnexal mass, and was useful for referring patients to tertiary care centers. Although utilization of RMI provides increased diagnostic accuracy in preoperative evaluation of patient with an adnexal mass, new diagnostic tools with higher sensitivity and specificity are needed to discriminate ovarian cancer from benign masses.

The purpose of this study was to identify risk factors related to sexual function of women with coronary artery disease, and to determine the predictors of sexual function. The study design, a descriptive correlational study, was done through structural questionnaire and interview. A total of 50 subjects from C University Hospital at Kwang-ju city who have undergone coronary angiography at department of cardiology were observed and interviewed from Feb. 22, 1999 to March. 23, 1999. The number of affected vessels, the level of total serum cholesterol, and the ejection fraction of 2-D echo cardiography were analyzed to evaluate the severity of coronary artery disease. And also type A behavior pattern, health behavior, Brief Index of Sexual Functioning for Women (BISF-W) were measured. The data obtained were analyzed using percentage, mean and standard deviation, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression analysis via SPSS PC+. The results of this study were as follows: 1. The mean age of the subjects were 58.1 and 72.0% of those have been married over 30 years. Seventy two percentage were unemployed and monthly family income of 56.6% was less than 1,000,000 won (approximately $ 840). Eighty percent were in their postmenopausal state, and the frequency of sexual intercourse of 84.0% were two to three times per month. 2. The scores of type A behavior pattern were from 16 to 38(mean 24.94) and health behavior ranged from 21 to 43(mean 31.2). Abstinence from smoking, alcohol, and caffeine were best compliant factors and weight control and exercise were least abided ones. The result of 2D-ECHO EF showed that the half of the subjects were abnormal, and 24% had more than 240mg/dl of total serum cholesterol. The coronary angiography showed that 64% of the subjects had more than one affected vessels. 3. The predictors to explain the factor score of 'orgasm' were number of health examination, the pre- or post-menopausal state, protestant, number of coronary vessel affected, level of serum total cholesterol, and comorbid group of hypertension and diabetes, and it's total variance accounted for 52.4%. The predictors to explain the factor score of 'sexual activity' were comorbid group of hypertension and diabetes and type A behavior pattern, which accounted for 22.4% of total variance. The predictors to explain the factor score of 'sexual satisfaction' were type A behavior pattern, no religion, exercise, level of serum total cholesterol, and pre or post menopausal state, which accounted for 52.1%. The predictors to explain the factor score of 'sexual desire' were the period of marriage, type A behavior, employment or unemployment, and weight control, which accounted for 43.2%. The predictors to explain the factor score of 'external force of sexual functioning' were physical overload and exercise, which accounted for 41.1%. The predictors to explain the factor score of 'sexual activity' were family monthly income, catholics, and exercise, and which accounted for 35.4%. Above results lead us to some consensus that sexual function of women with coronary artery disease is related to various factors including vasogenic factors such as total serum cholesterol level, number of coronary vessel affected, an endocrinal factor such as menopausal state, and type A behavior pattern as a sociopshychological factor. And also health behaviors such as fitness care, overwork, weight control, and emotional tension are contributed to sexual function.

The present study examined the reproductive factors and food intake pattern which influence on the breast cancer risk in Daegu${\cdot}$Gyungbuk area. The case subjects were 103 patients newly diagnosed as breast cancer at Kyungpook National University Hospital. The control subjects were 159 healthy women selected by frequency matching of age and menopausal status in the same community. The survey was conducted by individual interviews using questionnaires which include general and reproductive characteristics, dietary habits, and food frequency. The odds ratios were calculated by using unconditional logistic regression after adjusting for confounding variables. The mean age of the subjects was 50 yrs, and mean body mass index was significantly high in the patient group than in the control. The patient group had a significantly higher familial history of breast cancer and a significantly shorter breast-feeding period compared to the control group. It has been found no significant relationship between extrinsic hormone use such as oral contraceptives or estrogen replacement therapy and breast cancer risk. In regard of food habits, a high preference for the cooking method of steaming rather than frying, panbroiling or roasting was significantly associated with lower relative risk of breast cancer. The higher intake frequencies of fruits for all subjects, and seaweeds only for postmenopausal subjects were related with a significantly lower relative risk of breast cancer. The results of the study suggest that the possible risk factors for the breast cancer occurrence include high BMI, family history, less breast feeding experience, preference for the cooking method of frying, and less consumption of fruits and seaweeds. This study provides an useful data for nutrition education to prevent breast cancer for the residents in Daegu${\cdot}$Gyungbuk area.
