A nineteen year-old boy with progressive enlargement of the joints and distal extremities, clubbing, coarse facial features and hyperhidrosis was investigated. In physical examination, thickening of the scalp with furrowing (cutis verticis gyrata) and greasy thickening of skin (pachyderma) was prominent. His endocrine profile was normal. Radiological studies demonstrated bilateral symmetrical periosteal new bone formation with acroosteolysis and incidental microadenoma of pituitay gland. After extensive investigation to exclude systemic and endocrine causes, the patient was diagnosed as pachydermoperiostosis (PDP). PDP is a rare syndrome manifested clinically by finger clubbing, extremity enlargement, hypertrophic skin changes, and periosteal bone formation. The pathogenesis of the disorder has not been clarified though few endocrine abnormalities were seen. To aware of these clinical phenotype would help to differentiate PDP from acromegaly.

Purpose: This study was performed to evaluate changes in Achilles tendon (AT) characteristics of asymptomatic tendons in patients with acute AT ruptures on the contralateral side by using ultrasonography. Methods: From January 2016 to December 2018, 31 patients were enrolled. The contralateral asymptomatic ATs were assessed: (1) fluid collection of paratenon, (2) echogenicity, and (3) thickness. The ATs were divided into the distal, middle, and proximal thirds for evaluation and were assessed before the surgery, as well as at 6 weeks, 3 months, 6 months, and 12 months after the surgery. At each time, pain in the tendons was recorded. Results: In all cases, it was observed that there was a hypoechoic lesion or fluid collection of the paratenon, which did not show a significant change over time. There was no significant difference in tendon thickness according to the period in the distal and proximal areas, and significant differences were observed only in the middle area (p＜ 0.05). A new pain around the tendon occurred most often at 6 weeks after surgery (eight cases of 31 cases, 25.8%). Eight cases of pain (47.1%) remained at 12 months after surgery. Conclusion In patients with acute AT rupture, ultrasonographic hypoechoic lesions or fluid collections of the paratenon were initially observed on the contralateral tendon, but this did not show significant changes over time. A significant change in tendon thickness was observed in the middle area, but this did not show a close association with pain.

Thirty-one distal femoral and nine proximal tibial primary bone tumor patients who had prosthetic replacements were reviewed retrospectively. Average follow-up was thirty-eight months(range: 12- 109 months). There were thirty-two(osteosarcoma: 29, chondrosarcoma: 3) stage IIB lesions and eight 1B lesions(giant cell tumor). Twenty-nine patients were surviving at final follow-up. Overall prosthetic survival was 81%, 27% at 2 and 5 year respectively. Eleven prostheses were revised. The causes of revisions were infection(7), metal failure(2), fracture of host bone(1), and loosening(1). Eight revisions were successful, one was fair, and two patients needed an amputation. Prognostic factors which were analyzed for survival of prostheses were age, sex, location of primary lesion, percent of bone resected, and stage. Only the location of primary lesion showed statistical significance and diabolic pattern of survival curve was noted between two groups in resection length(<40% versus >40%). Average functional score was 26. The tibial side had worse prosthetic survival and a major threat to this procedure was due to infection.

It is generally considered that enteral feeding is superior to parenteral nutritional support. Thus enteral meal should be given whenever patients have proper gastrointestinal function to take enteral feeding. Because the morbidity and mortality for surgical jejunostomy have been reported as high as 50% and 10% respectively, direct percutaneous endoscopic jejunostomy has been developed to reduce the morbidity and mortality. A 55-year-old male patient, who was suffering from dysphagia and oropharyngeal aspiration, was transferred to the division of gastroenterology to be done permanent enteral feeding. His stomach was resected (subtotal gastrectomy with billroth II anastomosis) due to peptic ulcer hemorrhage 10 years before. We performed direct percutaneous endoscopic jejunostomy without any complication. Herein, we report a successful case.

PURPOSE: Although survival of osteosarcoma patient has markedly improved, cases of non-responders to chemotherapy and late-relapsers are still perplexing. Our strategy was to analyze the impact of chemotherapy and surgery on the survival for each stage, and to evaluate long-term survival and find prognostic factors within the same stage. MATERIALS AND METHODS: From May 1985 to Feb. 1999, 461 osteosarcomas were enlisted at our department and among them 348 cases were evaluable. There were 1 IB, 4 IIA, 302 IIB, and 41 IIIB. Two hundred and fifty-five (IIA/IIB:4/251) out of 348 cases followed our protocol of chemotherapy and surgery. Two hundred and ten cases had neoadjuvant chemotherapy and 45 had adjuvant only. RESULTS: Eleven year event free survival of the neoadjuvant group was 56.7%. On univariate analysis for 210 neoadjuvant cases, age (<13yrs), type of surgery (amputation), type of chemotherapy (methotrexate, adriamycin, cisplatin), pathologic response (>90%), local recurrence, pathologic fracture, location and size were statistically significant. But multivariate one revealed age, type of surgery, local recurrence and pathologic response as useful factors. There were 12 local recurrences (5.7%) and 100 metastasis among 255 stage II and their average onset from treatment was 17.8 month. Survival after metastasis was 5.6% at 55 months and the aggressively treated group made gains in survival (P<0.0001). Survival of 41 stage III was 0% at 64 months and this group also had an advantage in survival through intensive chemotherapy and surgery for primary and metastatic lesions (p=0.04). CONCLUSION: Long-term survival of the treated 255 stage II group was 55% at 14 years. For stage II: age, local recurrence and pathologic response were meaningful prognostic factors. Aggressive surgery and chemotherapy were necessary to improve the survival of stage III and stage II with late metastasis group.

PURPOSE: Soft tissue sarcomas have a wide variety of manifestation and its course is still unpredictable in many cases. This study altlempts to analyze the meaningful prognostic factors and to find optimal treatment strategies for each clinical stage. MATERIALS AND METHODS: From May 1985 to Mar. 1997, 432 soft tissue sarcomas were enlisted and 319 cases were eligible for this retrospective study. Staging followed AJCC classification and there were 34 stage I, 69 stage II, 151 stage III and 64 cases of stage IV. For stage I and II, operation was a major tool. Radiotherapy and chemotherapy were added for each situation. Intensive chemotherapy and surgery were done for stage III and IV. Metastasectomy was added in feasible cases. RESULTS: Actual survival rate for the 319 cases was 50% at 152 months. Disease free survival for stage I, II, III was 84%, 41%, and 38%, respectively. The stage itself had a statistical significance (P<0.00001). In univariate analysis, surgical margin in stage II and local recurrence in stage III had statistical significance. Multivariate study revealed the local recurrence as the only meaningful factor in stage I, II, III. An aggressive treatment for stage IV and I, II, III with late metastasis group had significant gain on survival. CONCLUSIONS: The stage itself predicts the course of soft tissue sarcomas. Evaluation of sound surgical margin to prevent the local recurrence is necessary.

OBJECTIVE: To understand the pathogenesis of adenomyosis through the immunohistochemical staining with bcl-2 and matrix metalloproteinase-9 (MMP-9) antibody. METHODS: We selected 45 cases of adenomyosis among the uterine specimens that were extirpated surgically due to benign gynecologic problem. Immunohistochemical staining to the myometrial tissue was performed using anti-bcl-2 and anti-MMP-9 antibodies. Staining was qualitatively assessed in terms of extent and intensity. RESULTS: There were 32 cases of proliferative phase and 13 cases of secretory phase depending on the date of endometrium. Anti-bcl-2 stained 81.3% (26/32) compared with anti-MMP-9 stained 6.3% (2/32) in the glandular tissue of the proliferative phase (p<.001). In the secretory phase, anti-bcl-2 92.3% (12/13) and anti- MMP-9 7.7% (1/13) respectively (p<.001). In the stromal tissue of the proliferative phase, anti-bcl-2 stained 62.5% (20/32) compared with anti- MMP-9 stained 6.3% (2/32) (p<.001). In the secetory phase, anti-bcl-2 84.6% (11/13) and anti-MMP-9 15.4% (2/13) (p<.001). CONCLUSION: The adenomyosis may be developed from simple invagination and cellular proliferation of endometrial tissue, not caused by myometrial infiltration of endometrial tissue.

Scalp avulsion is rare injury that has serious consequences, including hospitalization, economic loss, devasting disfigurement, and psychological effects on the patient. Microvascular surgery now allows an initial chance for successful replantation and one-stage reconstruction. The need for secondary reconstructive procedures after a successful replantation is minimal. Our one year experience with 2 patients who suffered from avulsion of partial scalp is reviewed. Each patient got long hair entangled in the uncovered rotated machines and underwent replantation using microsurgical technique. Replantations have been accomplished using only arterio-venous and venous-venous anastomosis, without arterio-arterial anastomosis in 2 cases, because of unidentification of suitable arteries. The possible explanation for the success of the operation is the paucity of valves that exist in the venous network of the scalp and forehead. The final results were good. In the follow-up period, both experienced regrowth of hair in the scalp with light touch sensation.

We present a case of recurrent left atrial myxoma which occurred 7 years and 10 months after initial operation despite resection of originaltumor and adjacent atrial septum. This is the first case report of recurrence in Korea. Among the possible causes of recurrence, regrowth from pretumorous focus seems to be the most suggesting one in this case. Histopathologic findings of recurrent myxoma showed increased cellularity with active proliferation and nuclear hyperchromasia. These findings, together with the rapidity of regrowth, suggest that recurrent myxoma may have 'wilder' behavior. Prolonged postoperative observation is important, even if ample resection was done at the initial operation including atrial septum.

PURPOSE: Combination therapy of alpha-blockers and 5alpha-reductase inhibitors (5-ARIs) is widely used for the treatment of benign prostatic hyperplasia (BPH). We aimed to study the effect on prostate volume and symptoms of shifting to monotherapy in patients who previously received a combination therapy. MATERIALS AND METHODS: A prospective study was conducted of 60 patients who were diagnosed with BPH. Patients were aged 45 years or older and had a prostate volume of 30 cc or more, International Prostate Symptom Score (IPSS) of 12 or above, maximal flow rate (Qmax) of 15 ml/s or less, and prostate-specific antigen (PSA) level of less than 10 ng/ml. The patients initially received a combination therapy of doxazosin 4 mg/day and finasteride 5 mg/day for 3 months and were then randomly assigned to receive monotherapy for 3 months. The factors were then compared. RESULTS: A total of 30 patients were assigned to doxazosin (group 1) and 30 to finasteride (group 2) after the combination therapy. The percentage changes in prostate volume, IPSS, and Qmax during the period from post-combination therapy to post-monotherapy were not significantly different between the two groups (p=0.052, 0.908, 0.081), whereas PSA significantly decreased in group 2 (p<0.001). IPSS was not significantly different at post-combination therapy and at post-monotherapy in both groups (p=0.858, 0.071). The prostate volume significantly increased from 40.97 cc at post-combination therapy to 44.29 cc at post-monotherapy in group 1 (p=0.001) and insignificantly increased from 38.32 cc to 38.61 cc in group 2 (p=0.696). CONCLUSIONS: Although the duration of drug administration was short in this study, 5-ARI monotherapy could maintain the alleviated symptoms and reduce the risk of acute urinary retention and surgery due to prostate regrowth in BPH patients whose symptoms improved with combination therapy.
