Uterine artery embolization for the treatment of uterine leiomyomas is gaining acceptance as an effective alternative to surgical treatment in preserving uterus and reducing symptoms. Vaginal expulsion of leiomyomas after UAE is uncommon, and has been regarded as a side effect of the procedure, as well as a natural phenomenon of treatment response. A-28-year-old unmarried woman who has been suffered from menorrhagia underwent UAE. MRI revealed the remnant leiomyomas were reduced in size and volume and also symptoms of leiomyomas were much improved. After 6 month, We've made sure about non-visualization of leiomyoma on follow-up pelvic dynamic MRI. We report this rare case of vaginal expusion of intramural leoimyoma with a brief literature.

OBJECTIVE: This study is aimed to evaluate the effects of cervical conization on sexual function in patients with non-malignant conditions. METHODS: We choose thirthy-one patients who were operated by cervical conization. They were interviewed retrospectically that effects on sexual desire or interest, sexual activity or frequency, pleasure, communication and satisfaction with sexual relationship. RESULTS: After cervical conization, there was no statistically significant change (p>.05) in sexual desire or interest, sexual activity or frequency, pleasure, communication and satisfaction with sexual relationship. CONCLUSION: Cervical conization was not found to have any adverse effects on sexual function in our study. In this respects, conization is a suitable conservative method when treating patients with non-malignant conditions.

PURPOSE: To evaluate the clinical and radiologic results of percutaneous surgical treatment of the intra-articular fractures of the distal radius, we have compared the results of percutaneous pinning and the combination of percutaneous pinning with external fixation after closed reduction. MATERIALS AND METHODS: We analysed the results of 52 patients with intra-articular fracture who received the operative treatment with closed reduction in the period of June, 1995 to June, 2001 and also were in regular follow-up at least one year. We used the subjective analysis by Cole & Obletz and the objective analysis by Scheck. RESULTS: We have found the outcome that 83.3% of percutaneous pinning were graded above "Good" in type B and C1 and 82.2% of the combination treatment of percutaneous pinning with external fixation were graded above "Good" in type C2 and C3. CONCLUSION: The percutaneous pinning and external fixator after closed reduction in intra-articular fractures of the distal radius are considered useful to restore the articular congruity and make good clinical results.

Purpose:
Breast cancer is known to be influenced by genetic and environmental factors, and several susceptibility genes have been discovered. Still, the majority of genetic contributors remain unknown. We aimed to analyze the plasma proteome of breast cancer patients in comparison to healthy individuals to identify differences in protein expression profiles and discover novel biomarkers.
Methods:
This pilot study was conducted using bioresources from Seoul National University Bundang Hospital’s Human Bioresource Center. Serum samples from 10 breast cancer patients and 10 healthy controls were obtained. Liquid chromatography-mass spectrometry analysis was performed to identify differentially expressed proteins.
Results:
We identified 891 proteins; 805 were expressed in the breast cancer group and 882 in the control group. Gene set enrichment and differential expression analysis identified 30 upregulated and 100 downregulated proteins in breast cancer. Among these, 10 proteins were selected as potential biomarkers. Three proteins were upregulated in breast cancer patients, including cluster of differentiation 44, eukaryotic translation initiation factor 2-α kinase 3, and fibronectin 1. Seven proteins downregulated in breast cancer patients were also selected: glyceraldehyde-3-phosphate dehydrogenase, α-enolase, heat shock protein member 8, integrin‑linked kinase, tissue inhibitor of metalloproteinases-1, vasodilatorstimulated phosphoprotein, and 14-3-3 protein gamma. All proteins had been previously reported to be related to tumor development and progression.
Conclusion
The findings suggest that plasma proteome profiling can reveal potential diagnostic biomarkers for breast cancer and may contribute to early detection and personalized treatment strategies. A further validation study with a larger sample cohort of breast cancer patients is planned.

The purpose of this study was to assess the antimicrobial and clinical effects of acid water mouthrinse prepared by an electrolysis apparatus on chronic periodontitis and to evaluate the lasting period of these effects. The change in the pattern of colonization of bacteria within the subgingival pockets was monitored by phase contrast microscopy, in 40 patients, over a period of 8 weeks. In addition, changes in the clinical parameters of the diseased sites were also monitored. Site of pocket > or = 5mm was selected in each patient randomly divided into two groups. As a test group, acid water mouthrinse was used twice a day in 20 patients. As control, no mouthrinse was used in 20 patients The results were as follows: 1. The suppression of motile bacteria was maintained for up to 3-4 weeks at test group. 2. Two groups did not differ significantly in proportion of bacteria in subgingival plaque over a period of 8 weeks. 3. Loss of attachment showed a significant difference in test group and in test group compared with control group (P<0.05), but there was no significant difference in control group. 4. No statistical difference was shown in two groups concerning the gingival index, plaque index, bleeding index. The results suggest that acid water mouthrinse is effective for reducing subgingival bacteria. It can be concluded that acid water may be useful as an mouthrinsing agent.

PURPOSE: To evaluate the modified Ender nailing technique for the treatment of femoral intertrochanteric fractures in elderly patients. MATERIALS AND METHODS: 31 cases of femoral intertrochanteric fractures treated by modified Ender nailing from May 1997 to December 2004 were included in this study. We analyzed the method of the anesthesia, amount of intraoperative blood loss, operation time, number of used nail, postoperative ability of ambulation, postoperative complication, and the time for radiological union. RESULTS: 22 cases were operated under epidural anesthesia and 9 cases under general anesthesia. The average amount of intraoperative blood loss was 55 ml and average time for operation was 37 minutes. The average number of used nails were 3.1. The postoperative ambulatory ability was clinically recovered to the preoperative ambulatory ability in 23 cases, and decreased than before in 8 cases. Postoperative complications included knee joint pain or limitation of motion of the knee joint and distal migration of the nails. The average time for radiological bone union was 17.1 weeks postoperatively. CONCLUSION: The modified Ender nailing technique is the one of the proper method in elderly femoral intertrochanteric fractures with associated medical problems. This method reduce the operation time and the amount of intraoperative blood loss.

Purpose:
Estrogen receptor (ER) expression in breast cancer plays an essential role in carcinogenesis and disease progression. Recently, tumors with low level (1%-10%) of ER expression have been separately defined as ER low positive (ERlow). It is suggested that ERlow tumors might be morphologically and behaviorally different from tumors with high ER expression (ERhigh).
Materials and Methods:
Retrospective analysis of a prospective cohort database was performed. Patients who underwent curative surgery for early breast cancer and had available medical records were included for analysis. Difference in clinicopathological characteristics, endocrine responsiveness and five-year recurrence-free survival was evaluated between different ER subgroups (ERhigh, ERlow, and ER-negative [ER–]).
Results:
A total of 2,162 breast cancer patients were included in the analysis, Tis and T1 stage. Among them, 1,654 (76.5%) were ERhigh, 54 (2.5%) were ERlow, and 454 (21.0%) were ER- patients. ERlow cases were associated with smaller size, higher histologic grade, positive human epidermal growth factor receptor 2, negative progesterone receptor, and higher Ki-67 expression. Recurrence rate was highest in ER– tumors and was inversely proportional to ER expression. Recurrence-free survival was not affected by hormonal therapy in the ERlow group (p=0.418).
Conclusion
ERlow breast cancer showed distinct clinicopathological features. ERlow tumors seemed to have higher recurrence rates compared to ERhigh tumors, and they showed no significant benefit from hormonal therapy. Future large scale prospective studies are necessary to validate the treatment options for ERlow breast cancer.

PURPOSE: We investigated the clinical outcome of bone marrow (BM) involvement in patients with diffuse large B-cell lymphoma (DLBCL) who received rituximab-based therapy. MATERIALS AND METHODS: A total of 567 consecutive patients with newly diagnosed DLBCL treated with rituximab-CHOP (RCHOP) between November 2001 and March 2010 were included in the current study. All of the patients underwent a BM study at the initial staging and the clinical characteristics and prognosis of these patients with or without BM involvement were analyzed retrospectively. RESULTS: The total cohort included 567 patients. The overall incidence of BM involvement was 8.5%. With a median follow-up duration of 33.2 months (range, 0.1 to 80.7 months) for patients who were alive at the last follow-up, the five-year overall survival (OS) and event-free survival (EFS) rate in patients without BM involvement (76.3% and 67.5%, p<0.001) was statistically higher than that in patients with BM involvement (44.3% and 40.1%, p<0.001). In multivariate analysis, among total patients, BM involvement showed a significant association with OS and EFS. In univariate and multivariate analyses, even among stage IV patients, a significant association with worse EFS was observed in the BM involvement group. CONCLUSION: BM involvement at diagnosis affected the survival of patients with DLBCL who received RCHOP. Although use of RCHOP can result in significant improvement of the therapeutic effect of DLBCL, BM involvement is still a negative prognostic factor of DLBCL patients in the era of rituximab.
