PURPOSE: Pigmented villonodular synovitis (PVNS) is a rare soft tissue tumor, which usually arises in larger joints, such as the knee. It has a high recurrence rate after surgical treatment. The purpose of this study is to evaluate and analyze the clinical results of diffuse-type pigmented villonodular synovitis cases that were treated with open total synovectomy. MATERIALS AND METHODS: Between 1994 and 2006, 21 patients who had diffuse-type pigmented villonodular synovitis were selectively reviewed. Among the 21 cases studied, 14 patients presented at the knee, 5 at the ankle, and 2 at the shoulder and elbow. The mean follow up period was 5.5 years (range, 36-157 months). The average age of the patients was 34 years consist of 7 men and 14 women. Clinical outcomes were analyzed retrospectively, including range of motion and complications. RESULTS: Open total synovectomy and adjuvant electrocautrization were done in all cases except one. During the regular follow-up period after the surgery, two patients showed symptoms of recurrence. After re-operation, only one case was pathologically confirmed as a recurrence. The patient who had partial synovectomy and the other patient who had second operation due to recur rence received additional radiation therapy. Clinical outcome scores were improved in every aspect (p<0.0001). 2 out of 14 Patients who had pigmented villonodular synovitis at the knee developed stiff knee after the surgery. CONCLUSION: After the open total synovectomy with electrocautrization, a low recurrence rate and satisfactory clinical outcome was achieved, observed in a minimum of 3 years of follow-up.

PURPOSE: We analyzed disease free survival and the prognostic factors of liposarcoma in the extremity. MATERIALS AND METHODS: Between 1994 and 2005, of 44 patients who were diagnosed and treated for liposarcoma of the extremity, 40 patients were restrospectively analysed. 13 out of 40 patients got postoperative radiotherapy. We examined local recurrence, distant metastasis and disease free 5-year survival rate. We also analyzed clinical prognostic factors, such as age, gender, size of tumor, prior unplanned excision, histologic type, surgical excision margin and postoperative radiotherapy respectively. RESULTS: There were 3 cases of local recurrence and 4 cases of distant metastasis. The disease free 5-year survival rate was 85.0%. 26 patients presented with myxoid, 8 well differentiated, 4 round cell, 1 pleomorphic and 1 dedifferentiated histology. The disease free 5-year survival rate of mixoid, well differentiated and round cell liposarcoma were 100.0%, 84.6% and 75.0% (p=0.419). The 5-year disease free survival rate was 90.6% in negative surgical margin (n=25) and 62.5% in positive surgical margin (n=15) (p=0.003). CONCLUSION: Our study suggests that surgical excision margin is significant prognostic factor for 5-year disease free survival rate.

BACKGROUND: Neutropenic fever is one of the most common and potentially severe complications of chemotherapy in pediatric oncology patients, while urinary tract infection (UTI) is one of the most prevalent bacterial infections in these patients. Therefore, this study was conducted to investigate features of UTI with neutropenic fever in pediatric oncology patients. METHODS: We retrospectively reviewed and analyzed the medical records, laboratory results and image findings of cases of neutropenic fever in the Department of Pediatrics of Yeungnam University Medical Center, South Korea between November 2013 and May 2015. Episodes were divided into two groups, UTI vs. non-UTI group according to the results of urine culture. The results were then compared between groups. The analysis was performed using IBM SPSS 23.0. A p-value <0.05 was considered to indicate a significant difference between groups. RESULTS: Overall, 112 episodes of neutropenic fever were analyzed, among which 22 episodes (19.6%) showed organisms on urine culture and were classified as UTI. The remaining 90 episodes were classified as non-UTI. Only four episodes (18.2%) of the UTI group showed pyuria on urine analysis. In the UTI group, 76.5% were sensitive to the first line antibiotics and showed higher clinical response than the non-UTI group. Among hematologic malignancy patients, the UTI group revealed higher serum β 2-microglobulin levels than the non-UTI group (1.56±0.43 mg/L vs. 1.2±0.43 mg/L, p<0.028). CONCLUSION: UTI in pediatric neutropenic fever responds well to antibiotics. Hematologic malignancy cases with UTI reveal increased serum β2-microglobulin level. These results will be helpful to early phase diagnosis of UTI.

PURPOSE: Hemangioma of the extremity is a painful soft tissue tumor. Many treatment modalities (surgical excision, sclerotherapy, radiation, etc) have been used, but results have rarely been reported. This study addressed the efficacy of surgical excision on hemangioma of the extremities. MATERIALS AND METHODS: Eighty cases were analysed, all diagnosed as hemangioma between January 1994 and September 2001, and were followed up for at least 1 year. The male to female ratio was 31: 49, and the mean age 22.1 years. Sixty-one of the cases received surgical treatment, nine cases sclerotherapy, and the other ten cases received both. RESULTS: The main complaint of 54 of the 71 people who received surgery, was pain. After surgery, 49 were completely relieved of pain, and the reminder showed more than 50% pain relief. The mean size of the mass was 6x4 cm, and in 49 cases, it was larger than 5 cm. Hemangioma recurred in 4 patients (5.6%), 3 of the 4 received sclerotherapy and surgical treatment, only one received excision. Complications requiring surgical treatment occurred in only 2 patients (2%). The most common type was cavernous hemangioma which occurred in 51 cases (71.8%). Nineteen patients who received sclerotherapy showed reduced pain to about 50% average. Retreatment was required after a 1.5 years interval. CONCLUSION: Surgical excision is a reliable treatment for pain relief and for removing symptomatic hemangioma.

20 Subjects with clinical diagnosis of adult periodontitis with sites having average pocket depth of 4mm were selected for the study. After scaling and root planing of those sites, 30% minocycline-HCl contained in biodegradable device were inserted in one group, scaling and root planing was carried out in another group and the last group was without any periodontal treatment. the difference between the groups was determined by pocket depth, bleeding on probing, attachment level, distribution of subgingival plaque bacteria. Conclusion was made for the comparisons between baseline and 4 weeks and the groups. 1. In analysis of pocket depth, there was significant difference in scaling and root planing group only. 2. Both the scaling and root planing group and minocycline group showed significant decrease in bleeding on probing. 3. There was significant increase in the attachment level in scaling and root planing group ,but no difference was foundbetween the groups. 4. There was significant decrease in the total number of subgingival bacteria in all groups and the number of motile bacteria decreased significantly in the minocycline group. These results indicate that insertion of Minocycline-HCl at the base of periodontal pocket was useful as an additional aid of mechanical treatment at the point of periodontal pocket, bleeding on probing, attachment level, microbial distribution.

The present study invetigates the effects of root planing only(control group) , DFDBA alone(test group 1) and combined use of DFDB and Dura mater(test group 2) in dehiscence defects in dogs. The results of 8weeks post-surgery by histological comparison between the three groups are as follows. 1. The contol group showed minimum regeneration of new cementum and new bone with limited migration of epitheilal cells, and healed by connective tissue attachment. 2. The test group 1 showed minimum regeneration of new cementum and new bone with limited migration of epitheilal cells, and healed by connective tissue attachment. 3. The test group 2 showed significant amount of the new cementum and new bone. 4. Both control and test groups healed without any observable root resorption and ankylosis. The above the results suggest that the use of resorbable Dura mater only does not improve the regeneration of new bone and periodontal ligament due to difficulties of space making, but the combined use with DFDB may be more effective.

PURPOSE: The purpose of this study is to determine the usefulness of arterial embolization on sacral and pelvic giant cell tumor (GCT). MATERIALS AND METHODS: We retrospectively reviewed the medical records of 9 patients who had undergone serial arterial embolization between December 1996 and May 2008. We analyzed the clinical outcomes and therapeutic responsiveness of arterial embolization on sacral and pelvic GCT. RESULTS: Six of 9 cases showed progression of disease (PD) status, even if 5 cases showed PD status despite of additional treatments including surgery and radiation, implying that serial arterial embolization on sacral and pelvic GCT is not effective. Three of 9 cases showed stable disease (SD) or continuous disease free (CDF) status and we analyzed associated factors with these good responses for embolization by chi2 test. The number of feeding vessels under six (p=0.048) and the number of collateral arterial supply under three (p=0.048) in the first angiogram showed significant relationships with good response for embolization, while remaining tumor staining by contrast after the first embolization and repeated embolization times were not significant. CONCLUSION: Although serial arterial embolization is not an effective modality on sacral and pelvic giant cell tumors, it may be a pilot modality under narrow indication of tumors with poor vascularity at first angiogram.

In this study, 21 patients diagnosed as adult periodontitis were divided into 4 groups. One quadrant with an average of 6mm deep pocket depth was chosen from each individual - Group A inserted tetracycline fiber after removing supragingival calculus while group RP had calculus removal and root planning alone. Group RP+A received combination of these treatments while group C received none. Plaque index, bleeding on probing, pocket depth, attachment level, and distribution of subgingival plaque were compared and evaluated among these groups at periods of first visit, 4th week and 8th week. The results were as follows; 1. Plaque index and bleeding on probing improved after treatment and no significant difference was found between the groups. 2. When comparing the change in pocket depth between the groups, the use of tetracycline fiber showed significant reducton in pocket depth comparable to root planing. Combined therapy of tetracycline fiber and root planing showed synergistic effect in pocket depth reduction. 3. When comparing the change in attachment level between the groups, the use of tetracycline fiber showed significant increase in clinical attachment level comparable to root planing, but no synergistic effect was found in the combined therapy. 4. When comparing the change in the motile bacteria ratio between the groups, group RP and group RP+A showed significant decrease compared with control group. 5. There were no severe adverse effects from using tetracycline fiber, except for a few patient who experienced mild discomfort. In summary, the use of local adminstration of tetracycline fiber in adjunction to mechenical treatment can be effective for adult periodontitis.
