The purpose of this study was to investigate the differences of knowledge and attitude level of breast feeding between breast feeding mothers and bottle feeding mothers. The subjects were mothers of 65 infants 1-6 months of age. Data were collected by a questionnaire on knowledge of breast feeding developed by Jung et al.(l994) and on attitude of breast feeding developed by Shin and Jeon(l996). The data was statistically analyzed according to Frequency, t-test, ANOVA and Pearson correlation coefficients. The results are as follows. 1) Degree of knowledge of breast feeding was significantly different according to child number(F=3.72, P<0.05) and delivery pattern(T=2.28, P<0.05) in breast feeding mothers. 2) There was a Significant difference on knowledge of breast feeding between breast feeding mothers and bottle feeding mothers(t=2.34, p<.05). 3) There was a statistical Significant difference on attitude of breast feeding between breast feeding mothers and bottle feeding mothers(t=3.05, p<.01). 4) The correlation between the mother's knowledge and attitude level of breast feeding was not found. Based on the results of this study, we suggest that systematic and supportive breast feeding program including knowledge and attitude of breast feeding have to be provided by nurse to mothers of infants to take an important role in breast feeding.

Background Currently, the BREAST-Q can effectively measure patient's satisfaction on the quality of life from the patient's perspective in relation to different type of breast reconstruction. However, evaluation of patient satisfaction and cosmetic outcomes in breast reconstruction may have potential to led bias. Methods To maximize the benefits of using BREAST-Q to evaluate clinical outcome, we performed comparative study focused on the correlation between postoperative BREAST-Q and cosmetic outcomes assessed by medical professionals. For the current analysis, we used three postoperative BREAST-Q scales (satisfaction with breast, psychosocial well-being, and sexual well-being). The Ten-Point Scale by Visser et al was applied to provide reproducible grading of the postoperative cosmetic outcomes of the breast. The system includes six subscales that measured overall aesthetic outcome, volume, shape, symmetry, scarring, and nipple-areolar complex. The photographic assessments were made by five medical professionals who were shown photographs on a computer screen in a random order. Obtained data were stored in Excel and evaluated by Spearman's correlations using SPSS Statistics. Results We enrolled 92 women in this study, 10 did not respond to all scales of postoperative BREAST-Q, the remaining 82 women had undergone breast reconstruction. The correlation between BREAST-Q score and aesthetic score measured by Ten-Point Scale for the three BREAST-Q scales all show positive values in Spearman's correlation coefficient. Conclusion A significant correlation without any bias observed was found between the patient's satisfaction measured by BREAST-Q after breast reconstruction and the medical expert's aesthetic evaluation.

Purpose: The purpose of this study was to examine the experiences of the use of external breast prostheses among breast cancer survivors in Korea. Methods: A qualitative descriptive study was conducted, using focus groups. Data were collected from breast cancer survivors who were patients of C women's hospital in Seoul, Korea. Data were analyzed using content analysis in order to identify significant themes. Results: Participants included forty breast cancer survivors who had mastectomy as a surgical treatment. Four themes emerged from the collected data were: 1) concern over the high price of external breast prosthesis, 2) irregular use of external breast prosthesis, 3) unsatisfied with mastectomy bra, and 4) wanting to hide or not to talk about using breast prosthesis openly. Conclusion: Since most participants reported irregular use and negative experiences related to external breast prosthesis or mastectomy bra use, healthcare workers should allow more time for proper fitting and counseling and consulting with breast cancer survivors. In addition, health care providers as well as family and friends should keep in mind that cancer survivors need support that can help them cope by using positive reframing. Furthermore, improvements in the coverage of costs and services are needed for these women. This would be helpful for breast prosthesis users.

The research subjects of this study were 30 unmarried Korean women from 20 to 29 who had never had an operation on their breast. Measurement method using plaster breast mold was used for measuring their volume of breast. The correlation between their breast volume and the methods to set up brassiere cups with the existing method and with their circumference of breast was analyzed using KendalI's Coefficient. which was to figure out a method which had a bigger correlation with the volume of breast between the method to set up brassiere cups using the existing method and the method using the circumference of breast. The results analyzed showed that the coefficient of correlation between the existing method and the volume of breast was .12 and the significance level was .45. They didn't have any correlation. On the other hand. the coefficient of correlation between the circumference of breast and the volume of breast was .82. which was very high values and the significance level was very high .0001. Therefore. it turned out that it was difficult to set up brassiere cups by using the existing method and it was easier and more reliable to set up the cups by using the circumference of breast.

Pax 6, a member of the paired box (Pax) family, has been implicated in oncogenesis. However, its therapeutic potential has been never examined in breast cancer. To explore the role of Pax6 in breast cancer development, a lentivirus based short hairpin RNA (shRNA) delivery system was used to knockdown Pax6 expression in estrogen receptor (ER)-positive (MCF-7) and ER-negative (MDA-MB-231) breast cancer cells. Effect of Pax6 silencing on breast cancer cell proliferation and tumorigenesis was analyzed. Pax6-RNAi-lentivirus infection remarkably downregulated the expression levels of Pax6 mRNA and protein in MCF-7 and MDA-MB-231 cells. Accordingly, the cell viability, DNA synthesis, and colony formation were strongly suppressed, and the tumorigenesis in xenograft nude mice was significantly inhibited. Moreover, tumor cells were arrested at G0/G1 phase after Pax6 was knocked down. Pax6 facilitates important regulatory roles in breast cancer cell proliferation and tumor progression, and could serve as a diagnostic marker for clinical investigation.

Breast feeding can play a very important role in the development of strong, healthy children. Many studies over the years have shown that breast milk provides defense against common ailments of childhood such as otitis media, gastrointestinal distress, and atopic diseases (allergies). For these reasons the American Academy of Pediatrics recommends breast feeding for at least the first twelve months of an infant's life. Goals of the Health People 2010 Initiative include that at least 75% of mothers will be breast feeding upon discharge from the hospital and at least 50% will be still nursing at six months post-partum. Currently, about 60% of new mothers initiate breast feeding and about 26% are still breast feeding at six months. However, research has shown that breast feeding trends are below these averages in rural areas of the United States. This may be due in part to lack of breast feeding knowledge and teaching in rural areas. Rural hospitals and birthing centers have not initiated many of the breast feeding promotional programs, such as the Baby Friendly Hospital Initiative and Best Start, that have been successful in improving breast feeding trends in urban areas. Often new mothers who live in rural areas do not have access to a lactation consultant to help them with proper follow up. This paper will examine these concerns and propose recommendations to improve breast feeding in rural areas.

Background: Fragile histidine triad (FHIT) gene is a tumor suppressor gene which involved in breast cancer pathogenesis. Epigenetics alterations in FHIT contributes to tumorigenesis of breast cancer. Objective: Our objective was to study FHIT promoter region hypermethylation in Egyptian breast cancer patients and its association with clinicopathological features. Materials and Methods: Methylation-specific polymerase chain reaction was performed to study the hypermethylation of FHIT promoter region in 20 benign breast tissues and 30 breast cancer tissues. Results: The frequency of hypermethylation of FHIT promoter region was significantly increased in breast cancer patients compared to bengin breast disease patients. The Odd's ratio (95%CI) of development of breast cancer in individuals with FHIT promoter hypermethylation (MM) was 11.0 (1.22-250.8). There were also significant associations between FHIT promoter hypermethylation and estrogen, progesterone receptors negativity, tumor stage and nodal involvment in breast cancer pateints. Conclusions: Our results support an association between FHIT promotor hypermethylation and development of breast cancer in Egyptian breast cancer patients. FHIT promoter hypermethylation is associated with some poor prognostic features of breast cancer.

This study provides basic data to develop a brassiere pattern that can cover the big breast of breast enlargement patients. In this study, we also showed areas of the brassiere cup pattern and the body surface of the breast on a breast enlargement patient. The results of the study are as follows. Correlation analysis was obtained between volume and body surface area and breast detail dimensions. After the correction process, we proposed a research bra pattern for breast augmentation patients. The cup-boundary in bra patterns of breast enlargement surgery patients is longer than the bra patterns of the general breast; therefore, the height of the inner and outer edges of the upper cups is higher. Also, it is necessary to set the new breast upper point when measuring the upper length in patients with breast augmentation surgery because the points of circumference of the breast are marked higher than chest circumference.

Purpose: In performing breast reconstruction, making symmetrical breast is still a challenge. A precise estimate of the volume of the breast specimen is necessary to reconstruct a symmetrical and aesthetically pleasing breast. This study aims at finding out the relationship with breast tissue density and body mass index designed to apply for breast reconstruction. Methods: By using the Archimedes' principle, the authors calculated the volume of the breast specimen and drew a correlation between the density of breast specimen and BMI. From October 2002 to November 2004, this method was used on 197 patients to predict breast volume for TRAM flap reconstruction. Results: The mean density was 0.9954g/cc and had no correlation with BMI (p-value=0.069). There was no difference between denstiy of breast tissue after skin spared mastectomy and that of breast tissue after nipple spared mastectomy. Conclusion: These data will be helpful to predict the needed volume for breast reconstruction.

Mammography, conducted every two years, causes cancer due to regular exposure to radiation while reducing rate of death caused by breast cancer. The study evaluates the effect of breast shielding apron made to shield off scattered radiation that occurs to the breast when the opposite side breast is mammogramed. AGD was measured using ACR phantom, composed of 50% mammary glands and 50% fat, and radiation was measured before and after wearing the apron on the breast when the opposite side of the breast is mammogramed. When CC direction mammography was conducted to a breast, the AGD was 1.84 mGy. When CC direction and MLO direction mammography were done to a breast, the average dose detected from the opposite side breast from four directions(top to bottom and medial to lateral) was $140{\mu}Gy$ with maximum dose of $256{\mu}Gy$ at medial side. After putting on the apron, the dose, caused by scattered radiation, was not detected from any of the four directions. Using of breast shielding apron is expected to minimize the radiation exposure by blocking scattered radiation to the breast shielded, when mammography is done to the opposite side breast.
