1.Current Status of G-CSF Based Stem Cell Therapy for Patients with Myocardial Infarction.
Hanyang Medical Reviews 2006;26(2):69-74
Stem cell therapy using mobilized peripheral blood stem cells with G-CSF is considered a promising alternative of bone marrow stem cell therapy. G-CSF based therapy has many advantages compared to stem cell therapy using bone marrow stem cells, including noninvasiveness and direct protective effects on cardiomyocytes. Results from clinical trials using G-CSF mobilization alone showed mixed outcomes. However, additional intra-coronary infusion of mobilized stem cell by G-CSF showed better and consistent improvement in outcomes than G-CSF mobilization alone. Safety concerns about G-CSF raised by earlier clinical trials, such as aggravation of restenosis, were mostly resolved by recent clinical trials. However, long term safety and efficacy of stem cell therapy should be carefully evaluated by further studies. Current efficacy of stem cell therapy should be improved by tailored therapy for individual patients and optimized by modification of current stem cell therapy.

The effectiveneas of compression plate fixation in promoting fracture healing could be due to a specific stimulus of compression on bone formation or to enhanced immobilization. ASI type heavy plate fixation for fracture of the femoral shaft was examined on occasions in three patient in the period 1971–1973. We believe that the major effect of the compression as applied through a compression plate is that of enhanced stabilization.

Hereditary ovarian cancer accounts for about 5% to 10% of the total ovarian cancer bnurden, The discase has been observed in context with three types of hereditary ovarian cancer prone syndrome : (1) site-specific ovarian cancer, (2) hereditary breast/ivarian cancer syndrome, (3) hereditary nonpolyposis colorectal cancer(Lynch syndrome II). Each of these syndmmcs is chracterized by autosomal dominant transmission of cancer, sigrdficant early age of onset, and exeess of multiple Iprimary cancers.

Malignant gastrointestinal stromal tumors (GISTs) are rare non-epithelial, mesenchymal neoplasms of the gastrointestinal tract that metastasize or recur in 30% of patients who undergo surgical resection with curative intent. A 59-year-old man visited our hospital for an examination of a palpable mass in the left abdomen. Fourteen months prior to his visit, the patient underwent gastric wedge resection to remove a GIST of the gastric cardia. At the time of surgery, no evidence of metastatic disease was observed and the pathological interpretation was a high-risk GIST. A follow-up computed tomography scan of the abdomen revealed a partially necrotic solid mass (9.8 x 7.6 cm) and enhancing mass in the spleen (2.3 cm). On exploration, multiple masses were found in the liver, greater omentum, and mesentery. Here, we report a case of recurring GIST of the stomach that metastasized to the spleen. To the best of our knowledge, few reports of metastasis to the spleen exist.

Objective:
To assess the contrast-enhanced CT and ultrasonography (US) findings of intracholecystic papillary neoplasm (ICPN) and determine the imaging features predicting ICPN associated with invasive carcinoma (ICPN-IC).
Materials and Methods:
In this retrospective study, we enrolled 119 consecutive patients, including 60 male and 59 female, with a mean age ± standard deviation of 63.3 ± 12.1 years, who had pathologically confirmed ICPN (low-grade dysplasia [DP] = 34, high-grade DP = 35, IC = 50) and underwent preoperative CT or US. Two radiologists independently assessed the CT and US findings, focusing on wall and polypoid lesion characteristics. The likelihood of ICPN-IC was graded on a 5-point scale. Univariable and multivariable logistic regression analyses were performed to identify significant predictors of ICPN-IC separately for wall and polypoid lesion findings. The performances of CT and US in distinguishing ICPN-IC from ICPN with dysplasia (ICPN-DP) was evaluated using the area under the receiver operating characteristic curve (AUC).
Results:
For wall characteristics, the maximum wall thickness (adjusted odds ratio [aOR] = 1.4; 95% confidence interval [CI]: 1.1–1.9) and mucosal discontinuity (aOR = 5.6; 95% CI: 1.3–23.4) on CT were independently associated with ICPN-IC.Among 119 ICPNs, 110 (92.4%) showed polypoid lesions. Regarding polypoid lesion findings, multiplicity (aOR = 4.0; 95% CI: 1.6–10.4), lesion base wall thickening (aOR = 6.0; 95% CI: 2.3–15.8) on CT, and polyp size (aOR = 1.1; 95% CI: 1.0–1.2) on US were independently associated with ICPN-IC. CT showed a higher diagnostic performance than US in predicting ICPN-IC (AUC = 0.793 vs. 0.676; p = 0.002).
Conclusion
ICPN showed polypoid lesions and/or wall thickening on CT or US. A thick wall, multiplicity, presence of wall thickening in the polypoid lesion base, and large polyp size are imaging findings independently associated with invasive cancer and may be useful for differentiating ICPN-IC from ICPN-DP

OBJECTIVE: To test the hypothesis that a safety margin may affect local tumor recurrence (LTR) in subsegmental chemoembolization. MATERIALS AND METHODS: In 101 patients with 128 hepatocellular carcinoma (HCC) nodules (1-3 cm in size and < or = 3 in number), cone-beam CT-assisted subsegmental lipiodol chemoembolization was performed. Immediately thereafter, a non-contrast thin-section CT image was obtained to evaluate the presence or absence of intra-tumoral lipiodol uptake defect and safety margin. The effect of lipiodol uptake defect and safety margin on LTR was evaluated. Univariate and multivariate analyses were performed to indentify determinant factors of LTR. RESULTS: Of the 128 HCC nodules in 101 patients, 49 (38.3%) nodules in 40 patients showed LTR during follow-up period (median, 34.1 months). Cumulative 1- and 2-year LTR rates of nodules with lipiodol uptake defect (n = 27) and those without defect (n = 101) were 58.1% vs. 10.1% and 72.1% vs. 19.5%, respectively (p < 0.001). Among the 101 nodules without a defect, the 1- and 2-year cumulative LTR rates for nodules with complete safety margin (n = 52) and those with incomplete safety margin (n = 49) were 9.8% vs. 12.8% and 18.9% vs. 19.0% (p = 0.912). In multivariate analyses, ascites (p = 0.035), indistinct tumor margin on cone-beam CT (p = 0.039), heterogeneous lipiodol uptake (p = 0.023), and intra-tumoral lipiodol uptake defect (p < 0.001) were determinant factors of higher LTR. CONCLUSION: In lipiodol chemoembolization, the safety margin in completely lipiodolized nodule without defect will not affect LTR in small nodular HCCs.

This study was conducted to compare the date on knowledge, attitude and motivation toward blood donation between donors and non-donors. The study population included 622 donors and 322 non-donors who visited the mobile blood donation car of Taegu Red Cross Blood Center and participated the group appointed blood donation campaign managed by the center from March 1 to March 31, 1989. The donors and non-donors were questioned above mentioned items with a formulated questionnaire. Among the general characteristics of the subjects in the study, male predominance (84.1% in donors and 73.6% in non-donors) in young age group (16-24 years) was the outstanding feature. As a medium of information about blood donation, “television” was playing a dominant role (donors; 75.2%, non-donors; 78.9%), while “magazine” played more important roles among donors. Of the donors, 70.6% and of the non-donors, 58.1 replied that they had ever been induced to donate blood (p<0.01). Major inducers were friend and personnel of mobile blood donation vehicle. On the measuring of knowledge level, the average rates of correct answer was higher in donors (62.6%) than in non-donors (54.1%) (p<0.01). Higher the education level was presented, higher the knowledge level (p<0.05). There have been noticeable difference between donors and non-donors in blood replying the questionnaire set to measure their attitude toward blood donation, especially in the items such as “impression toward blood”, “selection of transfusion blood source” and “view on the situation of blood shortage.” The major motivation toward blood donation of the groups were “possible future need” and “altruism or humanitarian interest”. The major reasons for not donation blood in both groups were “fear of the needle” and “dread to visit to mobile car or center”.
