Cystadenoma of the liver is a rare neoplasm. Although many cystadenomas are asymptomatic, symptoms can include abdominal pain, postprandial epigastric discomfort, and nausea. Dramatic changes in hepatic imaging techniques have been helpful for diagnosing cystic lesions of the liver, such as simple cyst, hydatid cyst, cystadenoma, cystadenocarcinoma, and metastatic neuroendocrine tumors. However, it remains difficult to differentiate cystadenoma from cystadenocarcinoma for multiseptated cystic hepatic lesions with papillary projection on computed tomography (CT) and magnetic resonance imaging (MRI). Here we report the case of a 47-year-old woman with several months of postprandial discomfort and abdominal fullness. CT and MRI revealed multiseptated cystic lesions with papillary excrescences. A left hemihepatectomy was performed. Histology showed a benign mucinous cystic tumor with ovarian-like stroma.

The purpose of this study was to evaluate the characteristics of craniofacial skeleton on orthognathic surgical cases with skeletal Class III malocclusion. For this study, 74 students at the dental college of Chosun University volunteered as a normal occlusion group. They had well-balanced faces and good occlusions with acceptable Class I molar relationship. They had not received orthodontic treatment and had no signs or symptoms of temporomandibular joint dysfunction. 45 malocclusion patients enrolled for orthognathic surgical treatment with skeletal Class III malocclusion at the Department of Orthodontics, College of Dentistry, Chosun University. On the basis of this study, the results of this study were as follows: 1. Skeletal Class III malocclusion was largely due to the overgrowth of mandible in man and the undergrowth of maxilla in woman. 2. The mandible was antero-inferiorly overgrown by large MP-HP angle and large gonial angle in orthognathic surgical cases with skeletal Class Iii malocclusion. And also, upper incisors were severely labioversioned, but on the other hand lower incisors were linguoversioned. 3. In female, lower-third facial height was characteristically shortened in comparison with middle-third facial height and also, lower facial throat angle was sgrall in male.

The purpose of this study was to evaluate the histologic difference that occured after trichloroacetic acid(TCA) chemical peel in an animal model that was pretreated with Tretinoin alone or Tretinoin-based combined pretreatment kit. Eight Hartley white guinea pigs were used in our study. The dorsal skin of the guinea pigs was divided into six equal squares(2x2 cm). Upper two areas of these six were not pretreated, middle two areas were pretreated for 4 weeks with Tretinoin alone and lower two areas were pretreated for 4 weeks with Tretinoin-based combined kit. Each guinea pig underwent chemical peel with 50% TCA. The wounded areas were biopsied at post-peeling 3 weeks and 6 weeks. The histology revealed that those animals pretreated with combined kit healed quicker than the animals pretreated with Tretinoin alone. This study implies that if patients are treated with Tretinoin-based-combined pretreatment kit before undergoing chemical peel, the pretreatment time will be shortened.

PURPOSE: High frequency oscillatory ventilation (HFOV) is used to support infants with severe respiratory failure unresponsive to conventional ventilation (CV). We reviewed chest radiographs before and after HFOV with clinical correlation in infants with respiratory distress syndrome (RDS). METHODS: Eighteen very low birth weight infants with RDS who had HFOV were included in this study. All patients were diagnosed as having RDS clinically and radiologically. Mean gestational age of infants was 27 weeks (range : 24-31 weeks). The mean duration of HFOV was 3 days (range : 14 hours-9 days). The chest radiographs of these infants within 3 hours before and after application of HFOV were retrospectively reviewed. Radiological findings based on aeration and parenchymal densities were classified into improved, no change, and progressed. Medical records were reviewed for FiO2 levels, clinical outcomes, complications, and causes of death. RESULTS: In 15 of 18 infants, aeration and parenchymal densities were improved and FiO2 levels were also improved after HFOV. Four of these 15 infants who showed improvement of radiological findings developed pneumothorax, sepsis, pulmonary or intestinal bleeding, and subsequently died. In remaining 3 infants in whom chest radiographs after HFOV showed no interval change or progression, oxygenation was also worsened and all died. CONCLUSION: Chest radiographs of HFOV-treated, very low birth weight infants showed improvement of aeration and parenchymal densities in most cases. Clinical outcome was good in infants who showed improvement on chest radiographs compared to those of progression group as far as there was no associated complication. Knowledge of radiological changes after HFOV will help in interpretation of chest radiographs in those HFOV-treated infants.

OBJECTIVES: Breast conserving surgery (BCS) for early breast cancer is now an accepted treatment, but there are controversies about its comparability with mastectomy. Thus, we investigated the survival outcomes who underwent BCS and modified radical mastectomy (MRM). METHODS: In this retrospective review, we analyzed the survival outcomes of 618 patients with early breast cancer who underwent two different surgery from January 2002 to December 2009. Postoperative pathologic difference, disease free survival period, overall survival period, recurrence pattern, recurrent rate and site were compared. In addition, preoperative patients data are also collected. RESULTS: Disease free survival period of MRM and BCS was 108.46 months and 80.82 months, respectively (P < 0.01). However, there was no significant correlation between overall survival period and operative methods (P = 0.67). In addition, recurrence pattern (P = 0.21), recurrent rate (P = 0.36) and site (P = 0.45, P = 0.09) were not associated with operative method. CONCLUSIONS: In this study, we can suggest that early breast cancer patients could improve their disease free survival if they underwent MRM. So, when we operate high risk breast cancer patients, MRM could be considered for their disease free life. Further studies may be required to establish appropriate strategy of surgery for early breast cancer.

PURPOSE: The purpose of the study were to categorize the subjectivity of the quality of life in elderly women and to thereby understand the differences regarding quality of life desires. METHODS: This study used a Q-methodology to measure the quality of life in elderly women. A Q sample was collected from in-depth and objective interviews and WHOQLO. Fourteen participants rated 28 selected Q-statements on a scale of 1-7. The collected data was analyzed using PC Quanl. RESULTS: The principal component analysis identified 4 factors regarding the quality of life of elderly women. These categories were labeled 'hopelessness-oriented', 'relationship/adaptation-oriented', 'physical suffering-oriented', and 'self satisfaction-orientated'. CONCLUSION: Some of the factors regarding the quality of life of elderly women were determined through this research. Further research is necessary to set up and apply different the quality of life between men and women based on this result. The results of this study indicate that different approaches toward quality of life promotion programs are recommended based on the four factors of quality of life among elderly women.

PURPOSE: This study aims to understand the influence of college entrance system-related factors and scores of college scholastic ability test on a first year nursing student's academic achievement. METHODS: Data collected include both a descriptive survey designed to assess college entrance system-related factors with respect to 182 nursing students attending a 4-year nursing college program and their test scores in the first year. The data were analyzed via descriptive statistics, Mann-Whitney U test, Kruskal-Wallis test with Bonferroni's correction, and Spearman's rank correlation coefficient through an SPSS 18.0 program. RESULTS: Student academic achievement with regard to college entrance system-related factors exhibited significant divergence from first year grade point averages (hereafter GPA) and natural science grades. CONCLUSION: This study confirmed the existence of significant differences, depending on the factors regarding the college entrance system. As a result, conducting assessment to evaluate the level of basic knowledge before college entrance is highly recommended. Also recommended is the development of a support program for students projected to have difficulties with respect to their academic achievement.

PURPOSE: To determine the significance of anomalous position of the gallbladder. MATERIALS AND METHODS: Sixteen patients with anomalous position of the gallbladder were evaluated for analysis. The diagnosis was confirmed by ultrasonography(15 patients) and oral cholecystography(1patient). Among those, six patients underwent CT scan and a patient had 99mTc-DISIDA scan. The images were analysed with respect to the location of the GB and configuration and associated abnormality of the liver and hepatobiliary systems. Medical records of each patient were also reviewed. RESULTS: Among 16 patients having an anomalous position of the gallbladder, nine had retrodisplaced gallbladder, four had left-sided gallbaldder, two had suprahepatic gallbladder, and one had floating gallbladder. Except for one patient, fifteen had abnormality in the liver such as focal atrophic or hypoplastic change and liver cirrhosis. Intrahepatic stones were demonstrated in 6 patients. CONCLUSION: Our results showed that anomalous position of the gallbladder was commonly associated with atrophy or hypoplasia of the liver rather than congenital in origin. The possiblity of an anomalous location of gallbladder should be kept in mind when GB is not in its normal location.
