PURPOSE: To evaluate the US findings of soft tissue hemangiomas in extremities and to correlate the echo-pattern with MR signal characteristics of hemangiomas. MATERIALS AND METHODS: We retrospectively studied forty-two patients either with pathologically proven cases or with characteristic features of hemangiomas on MRI, US and plain film. Hemangiomas were divided into two types according to the locations;subcutaneous and intramuscular. Analytic points on US and MR findings were gross morphology of the mass, internal echo-pattern or signal characteristics. We correlated the echo-pattern with MR signal characteristics in hemangiomas. RESULTS: Subcutaneous hemangiomas revealed homogeneously anechoic mass on US, which were well correlated with MR signal characteristics' homogeneous low singnal intensity(SI) on Tl-weighted image(WI) and high SI on T2-WI. Intramuscular hemangiomas showed heterogeneously mixed echoic masses on US. An anechoic component on US corresponded to dilated vascular channels on MRI. The signal intensity of intramuscular hemangioma was less than that of subcutaneous fat on T1-WI and greater than that of fat on T2-WI. Both types of hemangiomas had tubular or lace-like appearance with interspersed fibrofatty septa. CONCLUSION: The echo-patterns in US were well associated with MR signal characteristics on MRI. Regarding US and MR features, intramuscular hemangiomas were different to subcutaneous hemangiomas.

PURPOSE: The purpose of this study was to integrate and synthesize findings from qualitative studies exploring male students' experiences of adapting to nursing education programs so as to obtain further understanding of the phenomenon. METHODS: The meta-synthesis process was primarily guided by Noblit and Hare's approach, which consists of four stages including searching, appraisal of an individual study's quality, data extraction for analysis, and meta-synthesizing the results. RESULTS: Findings from the literature reviewed were synthesized into six themes: 1) extraordinary choice based on job stability and gender scarcity; 2) unexpected feeling of marginalization as minority far apart from the mainstream; 3) assimilation and negotiation for relational adaptation through perspective shift; 4) fortifying the vision and identity as nursing students by meaning making for adapting to the nursing major; 5) mutual support among colleague male students; and 6) serving in the military as way of hiding out and achieving maturation. CONCLUSION: The findings illustrate that nursing education programs need practical changes promoting male students' adaptation to the program itself as well as preparation to be a professional nurse in the future.

It is well known that the spatial patterns of basement membrane[BM] components show a close correlation with the morphogenetic process in developing organs during pre- and postnatal period. But little is known about the chronological changes in BM components during the development of thyroid gland. To investigate the correlation of the distribution of BM components with the development of the thyroid gland, immunohistochemical localization of the BM components was performed, using rat fetuses[from 15 to 21 days of gestation] and pups[from 1 to 14 days]. According to the histological features with H.E. staining, prenatal development[El5-21] of the rat thyroid could be divided into 3 representative stages : 1] Undifferentiated primordium of thyroid epithelia, forming cell cords or cell nests [until El5 day]. 2] An intervening stage of cell proliferation with the pattern of lobulation[El6-17 days]. 3] Stage of maturing follicles[El8-21 days]. It could be concluded that differentiation of the thyroid follicle are terminated during the prenatal period and growth in size and number occurs during the first two weeks after birth. By the immunohistochemical localization of laminin[LM], fibronectin[FN], type IV collagen[CIV], the basement membranes investing thyroid follicles could be clearly delineated at 15 days of gestation. Reactivity for LN and CIV associated with BM increased with advancing development, while that of FH was apparently weakened during the 2 weeks after birth. On the other hand immunoreactivity for CIV in the same age group increased, compared to that of previous swage of development. These results indicate that BM components were expressed in distinct spatial patterns with advancing development of thyroid gland. Based on these observations, it could be concluded that these BM components are important determinants in epithelial growth and differentiation during thyroid development.

OBJECTIVES: This study was designed to investigate factors affecting the discordance between body image and body mass index amongst Korean adults aged 19–39 years. METHODS: Data (N = 59,361) from the 2014 Korean Community Health Survey was analyzed using descriptive analysis, chi-square test, and logistic regression analysis. RESULTS: To examine the factors affecting body image discordance as observed in 43.1% of participants, the group was subdivided into underestimation and overestimation. There were 36.0% of participants that were body image discordant underestimators and 7.1% were overestimators. Multivariate logistic regression analysis showed that the underestimators tended to be men, graduated from high school, married, current/ex-smokers, ex-drinkers, had between 5 to 9 hours sleep (inclusive), had fair to good self-rated health, and demonstrated healthy weight control behavior, relative to the reference group. In comparison, overestimators tended to be in the 19–29 year group and had signs of depression. The OR of individuals who were men, married, and had healthy weight control behavior was significantly lower in the overestimators group. CONCLUSION: These findings show that tailored interventions to promote accurate body awareness should be based on the type of body image discordance. In addition, it is necessary to develop and implement a program of body image improvement that considers the factors affecting body weight discordance.

Hemodialysis(HD)-associated hypotension is a frequent complication, but it is difficult to manage. Until now, several maneuvers have been tried to prevent the HD-associated hypotension. Of these, the sodium content of dialysate was regarded as an important factor for maintaining blood pressure during HD. In this study, we evaluated the effect of hypertonic dialysate on blood pressure, interdialytic weight gain and the incidence of thirst. The study was done for 6 weeks successively with 3 different groups. Each patient was dialysed with 3 different dialysates for 2 weeks: Group I(Conventional HD: sodium concentration: 137 mEq/L), Group II(Hypertonic HD: 147 mEq/L) and Group III (Sequential HD: from 147 to 140 mEq/L). Hemodynamic parameters(blood pressure, pulse rate and ultrafiltration rate), biochemical parameters(hematocrits, blood urea nitrogen, creatinine, osmolality, sodium, potassium, chloride, fasting blood sugar) and complications (interdialytic weight gain &thirsty sensation) were compared among 3 groups. The results were as follows: 1. Decline of systolic blood pressure and diastolic blood pressure at the time of a 3 hour check during hemodialysis was lower in the Group II than Group I and III (p=0.002; p=0.012). and decline of diastolic blood pressure at the time of a 4 hour check during hemodialysis was lower in the Group II and III than Group I(p=0.04). 2. ncidence of hypotensive episodes during dialysis was significantly lower in Group II than group I (p=0.0287). 3. The ultrafiltration in Group III at the time of 1 hour, 2 hour and 3 hour check during hemodialysis was higher than that in Group I and II at the time of 1 hour, 2 hour and 3 hour check during emodialysis respectively (p=0.0001; p=0.0001; p=0.0004). 4. Interdialytic weight gain was higher in Group II(3.1+/-0.8) than GroupI(2.8+/-0.8) and III (2.9+/-0.9) (p=0.0422). 5. Hematologic and biochemical results were not significantly different among 3 Groups. 6. Frequency of thirst was different in Group I, II and III, 0.05+/-0.12, 0.41+/-0.24 and 0.22+/-0.29 respectively (p=0.0259). The results suggest that hypertonic HD was effective in preventing HD-associated hypotension but interdialytic weight gain and thirst sensations were increased as compared with a conventional method. In this situation, sequential HD seems to be an alternative method to minimizes the side effect of hypertonic HD.

Nutrition during childhood is essential for growth and maintenance of health. Good food habits developed during the childhood will contribute both to the healthy growth and the prevention of the degenerative disease of later life. Both parents and the providers in child care centers play an important role for children's good eating behavior. Therefore all child care programs should achieve recommended standards for meeting children's nutritional and educational needs in a safe, sanitary, and supportive environment to promote the healthy growth and development of children. The purposes of this study were to evaluate the foodservice management practices and assess the needs for a Central Production Unit by contacting the child care center' providers. This approach was achieved using a variety of qualitative and quantitative information including the general foodservice management practices and the needs for a Central Production Unit. An indepth face-to-face interview with structured-questionnaires was undertaken at 32 representative child-care centers in Seoul. Statistical data analysis was done using the SAS program for descriptive analysis and ANOVA. The number of national/public and private sectors were 11 respectively, followed by 10 licensed home day-care centers. Total average number of children in child-care centers was 54.3+/-48.5. The foodservice productivity index in child-care centers was 4.8 minutes per meal for public child care centers, 6.0 for private child-care centers, and 9.8 for home child care centers. Home child care centers were found to have the lowest productivity index which indicated inefficient foodservice practice. The important factors in group purchasing were menus(39.6%) or close distance(39.6%) > type of foodservice operation(32.8%) > total number of meals(19.9%) > food costs(16.2%) in order. Average score of the efficiency for central food production in child-care centers was 3.80+/-0.84 out of 5.

A 44-year-old man presented with a history of chronic epiphora, discharge from the right eye, and a palpable mass in the medial canthal area. Irrigation of the lacrimal system revealed bloody discharge. Orbital magnetic resonance imaging (MRI) showed a well-defined heterogeneous enhanced mass filling the lacrimal sac and upper nasolacrimal duct (NLD). A wide excision and surgical biopsy were performed. Histopathology showed the tumor to be an exophytic Schneiderian papilloma with moderate to severe dysplasia. Three months later, the mass was found to be invading the nasal cavity through the NLD. Endoscopic histopathological evaluation confirmed that it was identical to the originally identified papilloma.

BACKGROUND: Recently, many cardiac centers have been using aprotinin to reduce operative bleeding in cardiac operations using cardiopulmonary bypass. A variety of reports have confirmed the effectiveness of the drug in cardiac operations. In addition to the operations which could be considered to cause severe operative bleeding such as redo operation, long cardiopulmonary bypass operation and etc, the use of aprotinin is increasing in the field of primary cardiac operations. Varying doses of regimen have been introduced since the first report by Royston et al, and also various opinions on the effectiveness and safeness of the each regimen have been reported. We reviewed our own experience of the full dose aprotinin regimen(Hammersmith regimen) retrospectively. MATERIAL AND METHOD: From October 1994 to February 1998, 40 cases of cardiac operative patients were randomized into two groups: aprotinin group(20 patients) which received a full dose aprotinin regimen and control group(20 patients) which did not receive aprotinin. To evaluate the degree of bleeding decrease, we analysed and compared the amount of postoperative 6 hours and 24 hours bleeding in the each group. To confirm the renal dysfunction, we measured the postoperative creatinine level. RESULT: In the amount of postoperative 6 hours bleeding, a statistically significant bleeding decrease was demonstrated in the aprotinin group compared to the control group(aprotinin group: 186+/-40cc, control group:409+/-69cc, P=0.010). Similar result was observed in the postoperative 24 hours(aprotinin group:317+/-53cc, control group: 671+/-133cc, P=0.024). CONCLUSION: We concluded that full dose regimen of aprotinin can remarkably reduce postoperative bleeding in cardiac operations without significant renal dysfunctions.
