There is no definite histological criteria which can predict the biologic behavior of meningiomas, although resectability is the most important factor in terms of recurrence. For grading meningiomas, various factors have been studied, such as hypercellularity, nuclear pleomorphism, small cells with high N/C ratio, prominent nucleoli (PN), frequent mitosis, loss of architecture, focal necrosis (FN). We investigated 116 meningiomas to evaluate the correlation between the factors and the proliferative activity using AgNORs and MIB-1 labelling index (LI). They were divided into 3 groups: Group A includes meningiomas with none of the factors; group B with one of the factors; group C with two or more factors. MIB-1 LI was correlated with each factor, but AgNORs was not. There was a statistical difference among group A (<1.28%), B (2.7%) and C (5.1%) (p<0.05) using MIB-1 LI. FN was the most frequently associated with other factors, and it had the highest MIB-1 LI (6.31%). MIB-1 LI of group B was 5.1 2.3%. In group B, the most frequent combination was FN and PN, and it showed the highest MIB-1 LI (5.74%). This study indicates that FN and PN are important for diagnosis of atypical meningioma, and MIB-1 LI appears to be a useful method for estimating the proliferative activity of meningiomas, and 5% or more of MIB-1 LI could help in making a diagnosis of atypical meningioma.

PURPOSE: The purpose of this study was to offer basic data concerning the prevention of obesity for obese children to identify the relationship between their self-efficacy and the degree of performance on health promoting lifestyle profile. METHOD: The subjects were 148 fourth to sixth grade elementary school students in Gwang-ju, Korea during the period from September 10 to September 25, 2001. The collected data were analyzed by mean, standard deviation, t-test, ANOVA, Pearson's Correlation Coefficient and Stepwise Multiple Regression by using the SPSS program. RESULT: The relationship between general characteristics of subjects and self-efficacy were significant differences according to eating time(F=5.338, p=.006). The relationship between general characteristics of subjects and health promoting lifestyle profile were significant differences according to grade(F=5.615, p=.005), eating time(F=8.591, p=.000), concern about weight control(F=3.915, p=.022), experience of weight control(t=7.632, p=.006). Health promoting lifestyle profile was showed significant positive correlations with self-efficacy(r=.537, p=.000). Self-efficacy(27.6%) was the highest factor predictor health promoting lifestyle profile of obesity students. In addition to eating time, concern about weight control, explained for 33.3% in health promoting lifestyle profile. CONCLUSION: Results of this study point to self-dfficiency as a major factor in the health promoting behavior of childhood obesity. According to the results of this study, There is a reason to develop a health program to promote self-efficiency.

The secretary meningioma is a distinct variant of meningioma that revealed characteristic light microscopic, immunohistochemical and ultrastructural features of epithelial and secretary differentiation, which was named as a distinct subtype of meningioma by Alguacil-Garcia et al in 1986. We experienced 2 cases of secretary meningioma. One was a 53-year-old female who had suffered from sudden onset of dizziness for I day. The computerized tomography revealed a sharply marginated well enhanced mass in temporal lobe. The other was a 59-year-old female who had suffered from dizziness for 8 years. The computerized tomography revealed a well demarcated lobulated mass in petrosal ridge. In both cases, multiple hyaline inclusions were scattered in the background of meningothelial meningioma. They were PAS positive, diastase resistant, stained yellow with van Gieson, and did not stain with reticulin in contrast to Psammoma bodies. The immunohistochemistry revealed positive reaction for EMA, CEA, a-FP and cytokeratin. T'he electron microscopic study revealed interdigitation with desmosomes and abundant intracellular lumina. They were lined by numerous microvilli and filled with granular material which was composed of electron dense homogenous material, me branous material, and small membrane-bound vesicles. Microvilli were filled with electron dense material identical to the material in the lumina, and some of them were interconnected with electron dense material in the lumina. It was concluded that secretary activity of the meningothelial cells and degenerated microvilli were involved in the pathogenesis of hyaline inclusions.

In spite of vigorous efforts to enhance appropriateness of blood usage in surgery, it is recognized that there are still not a few overuse and misuse of blood products in Korean hospitals. To assure appropriate use of blood, continuous monitoring and controlfling blood orders, particularly for surgical operations, should be implemented. The indicator of 'ratio of crossmatching to transfusion' (C/T ratio) has been focalized on in this regard. The authors investigated C/T ratio for eight hospitals, evenly distributed in their geographical location as well as size. Only elective surgeries operated from March 1 to May 31, 1995 were included for analysis. Standardized survey format was distributed, and retrospective reviews of medical records were performed by volunteer surveyors from each hospital after two sessions of pre- survey education. The results were as follows. Average C/T ratio, for all hospitals and all surgeries, was 1.76. Differences in C/T ratio by sex, months, clinical departments, blood components were not significant. However, the ratio showed increasing tendency with ages. The C/T ratio on the average was not higher, compared with the recommended guideline. However, due to study' s limitations ini standardization of survey method and verification of data, we could not conclude that current status of appropriateness of blood use is satisfactory. In addition, to pervasively use the C/T ratio as a quality indicator for blood use management, supplementary measures, such as standardization of data, should be adopted.

OBJECTIVE: To study the clinical characteristics on translocation of intrauterine device and the methods of removal. METHODS: A retrospective review was performed on 77 cases of translocation of intrauterine device from June 1994 to December 2002. RESULTS: Among 77 cases undergoing removal of intrauterine device, 17 cases (22.1%) were translocted intraperitoneally. Fifteen cases were removed by laparoscopy, 2 cases were by laparotomy and there was no specific postoperative complication. The incidence of intraperitoneal translocation was not related to the type of IUD. Between intrauterine and extrauterine translocation, the incidence of symptoms were not different, but low abdominal pain were slightly increased in extrauterine (35.3%) than intrauterine (10.0%) group. The time lapse after insertion of IUD was ranged from 1 month to 35 year, the mean duration was 9.39 year, that was not related to the incidence of intraperitoneal translocation. In the cases of extrauterine translocation, the mean hospital day was significantly increased (p=0.001), the mean duration was 2.5 day (1-7 day), compaired with 0.7 day (0-6 day) of the cases of not translocated. CONCLUSION: As the type of IUD or symptoms, it is difficult to anticipate the possibility of the intraperitoneal translocation of IUD. But, in cases of extrauterine translocation of intrauterine device, the incidence of low abdominal pain was slightly increased, and ring type IUD was rarely extrauterne translocated. So, it is necessary to further study what factors contribute the extrauterine translocation of IUD.

By November 2013, a total of 125 clinical practice guidelines (CPGs) have been developed in Korea. However, despite the high burden of diseases and the clinical importance of CPGs, most chronic diseases do not have available CPGs. Merely 83 CPGs are related to chronic diseases, and only 40 guidelines had been developed in the last 5 yr. Considering the rate of the production of new evidence in medicine and the worsening burden from chronic diseases, the need for developing CPGs for more chronic diseases is becoming increasingly pressing. Since 2011, the Korean Academy of Medical Sciences and the Korea Centers for Disease Control and Prevention have been jointly developing CPGs for chronic diseases. However, priorities have to be set and resources need to be allocated within the constraint of a limited funding. This study identifies the chronic diseases that should be prioritized for the development of CPGs in Korea. Through an objective assessment by using the analytic hierarchy process and a subjective assessment with a survey of expert opinion, high priorities were placed on ischemic heart disease, cerebrovascular diseases, Alzheimer's disease and other dementias, osteoarthritis, neck pain, chronic kidney disease, and cirrhosis of the liver.

PURPOSE: As the use of hormone replacement therapy for the menopausal women increases, some caution is advised, since there is an increased risk of breast cancer. Accordingly, the importance of regular mammography has been addressed. This cross-sectional study analyzed the effects of different hormone therapies on mammographic density. MATERIALS AND METHODS: Sixty-seven postemenopausal women who had completed one year of hormone therapy and had undergone follow-up mammography, were divided into two groups : Group I : continuous conjugated equine estrogen, 0.625 mg, plus continuous medroxyprogesterone acetate, 2.5 mg (n=48), Group II : continuous conjugated equine estrogen 0.625 mg (n=19). The mammograms were read by two radiologists. RESULTS: With regard to the radiologists involved, interobserver reliability (kappa) was 0.70 and intraobserver reliability (kappa) was 0.51 and 0.67. Before hormone therapy, factors related to decreased mammographic density were age and number of full term pregnancies (p<0.05). After one year of hormone therapy, body fat showed a significant increase (p<0.05), but in spite of this, increased mammographic density induced by hormone therapy remained significantly high (p<0.05). Compared with Group II, Group I showed a significant increase in mammographic density (p<0.05). In Group I, mammographic density increased from P2 to DY pattern in two cases, but there was no such change in Group II. CONCLUSION: The increase of mammographic density seen in Group II was much more significant statistically than that seen in Group I. The mammograms of women who have undergone continuous combined hormone therapy should therefore be interpreted very cautiously.

Apoptosis is an intrinsic and fundamental biological process that plays a critical role in the normal development of multicellular organisms and in maintaining tissue homeostasis. Some of the well known regulators of apoptosis are cytokines of the tumor necrosis factor(TNF) ligand family, such as Fas ligand(Fas L) and TNF, which induce apoptosis by activation of their corresponding receptors, Fas and TNFR-1. Recently, a new member of the TNF family known as TRAIL (TNF-related apoptosis-inducing ligand) was identified and shown to induce p53-independent apoptosis in a variety of tumor cell lines but not in normal cells, Four human receptors for TRAIL were also recently identified and designated TRAIL-R1, -R2, -R3, and -R4. The aim of this study is to examine whether TRAIL and TRAIL receptots(-R1, -R2, -R3) are expressed in uterine cervical cancer and whether it is correlated with apoptosis, TRAIL and TRAIL receptors. The subjects were 20 patients who were diagnosed with cervical cancer. Western blotting was performed in 9 cases, immunohistochemical staining for TRAIL and TRAIL receptors(-R1, -R2, -R3) and TUNEL method for detection of apoptosis in 11 cases. There were proteins for TRAIL, TRAIL-R1, -R2, and -R3 in tissues from cervical cancer. All TRAIL receptors were expressed in both normal cervical epithelium and tumor cells, and TRAIL-Rl and -R2 were more strongly expressed in tumor cells than normal epithelium(p<0.05). Apoptosis correlated with expression of TRAIL-Rl and -R2(p<0.05). This study suggests that TRAIL induces apoptosis in cervical cancer through its receptors.
