Soft tissues, which are widespread in body, are derived from a common primitive mesenchyme and the tumors arising from them tend to closely resemble the prototype tissue in varying degree. Some soft tissue tumors have benign course, which can be cured by local excision and the other have malignant course being resistant to therapy and resulting in recurrence to other organ of tissues. The authors reviewed 279cases of soft tissue tumors which had been treated at Department of Orthopedic Surgery in Severance Hospital, Yonsei University College of Medicine from January 1983 to December 1987. 1. Among 279cases of soft tissue tumors, 257(92.1%) were benign and 22(7.9%) were malignant. 2. Benign soft tissue tumors were common two times in female, and malignant tumors were relatively common in male. 3. Common sites of soft tissue tumors were 92 csses about the knee, 69 csses in the hand and wrist, 44 cases in the foot, 26 cases in the leg, 15 cases in the thigh, 14 cases about the elbow, 10 cases in the arm and foresrm. 4. The most common benign tumors was ganglion which was followed by Baker's cyst, hemangioma, fibromatosis, lipoma, epidermal cyst in decreasing order of incidence. Among malignant tumors, fibrosarcoma, malignant fibrous histiocytoma, malignant schwannoma, synovial sarcoma, leiomyosarcoma were common. 5. Most of the benign tumors was taken by locsl excision, and malignant tumors were were trested by wide resection with combination of chemotherapy. 6. Local recurrences of benign tumors were developed in 26(10.1%) out of 257cases, especially in fibromatosis and hemangioma.

Idiopathic myelofibrosis (IMF), which is characterized by marrow fibrosis, leukoerythroblastic anemia, teardrop poikilocytosis and splenomegaly due to extrumedullary hematopoiesis, has known to have no form of therapy. On the ground of the possibility of reversing collagen deposion in IMF using 1, 25dihydroxycholecalciferol [1, 25(OH)2D3], we report here our observations of 5 patients (M:F=1:4) with IMF before and after treatment with 0.5 microgram/day of alfacalcidol, precursor of 1, 25(OH)2D3. In 3 fo 5 patients the hemoglobin rose and in 4 of 5 the platelet count increased. Follow-up marrow examination revealed that marrow trephine reticulin fibrosis decreased according as the amelioration of clinical and laboratory findings. But these did not persist except one patient in spite of the sustained use of alfacalcidol. Our results suggest that alfacalcidol may have a therapeutic role in some patients with IMF. More extensive studies will be clarify the action of alfacalcidol in IMF.

PURPOSE: It is controversial to treat complicated appendicitis in pediatric patients on several points, especially optimal time for appendectomy. The purpose of this study is to determine optimal time for operation in perforated appendicitis in pediatric patients. METHODS: Children with perforated appendicitis under the age of 14 underwent appendectomy between January 2006 and December 2008 at Ewha Womans University Mokdong Hospital were analyzed retrospectively according to factors which may affect the postoperative hospital course such as complications, time of beginning of diet, and length of hospital stay. RESULTS: During the study period, 357 patients with acute appendicitis underwent appendectomy and 118 patients were diagnosed with perforated appendicitis. Comparing symptom durations between more than 48 hours and less, the former induced significantly higher postoperative complication rates. Body temperature above 37.5degrees C at admission affected significantly higher complication rates and delay of beginning of diet. Children with intraabdominal abscess at appendectomy showed higher complication rates than without abscess. Children who underwent operation in the daytime started diet significantly earlier and showed less complication than those operated on at night. The frequency of preoperative antibiotics administration did not alter the postoperative hospital course. CONCLUSION: For the children diagnosed with perforated appendicitis, non-urgent appendectomy in the daytime after initial conservative management including intravenous administration of antibiotics, hydration, and correction of serum electrolyte is safer and more efficient than performing emergency operation, and moreover there is no necessity for secondary admission for interval appendectomy.

The facial patterns were expressed by the interrelation of variable factors such as heredity, function and environment. Such variable factors have an effect on the growth and development of maxillofacial bones. The malocclusions with skeletal discrepancies are caused by abnormal forms, sizes and positions of cranial base, maxilla and mandible. For the proper diagnosis and treatment planning, the analysis of such structures is necessary. Lateral cephalograms of 54 adults with class III malocclusion patients (test group) and 61 adults with normal occlusion (control group) were analyzed. Anteroposterior relations and sizes of cranial base, maxilla, mandible were estimated to compare with those of normal ones. In test group, the anterior cranial base length was within normal range, but posterior cranial base, maxilla and mandibular body were longer than those in control group, significantly. Based on the cranial base, the location of maxilla in test group was normal, but the location of mandible was more anterior than that in control. Based on the maxilla, the location of mandible was more anterior in test group than that in control. Both mandibular body and ramus anteroposterior lengths in test group were larger than those in control. Both mandibular plane angle and upper gonial angle were within normal range, but lower gonial angle was significantly high in test group.

OBJECTIVE: To identify and localize the Placenta Growth Factor (PlGF) mRNA in term placentas and to determine whether there are any differences in the expression of PlGF mRNA in the placentas between normal and preeclamptic pregnancy. METHODS: Northern blot and In situ hybridization with 5 cases of preeclamptic placentas and 8 cases of normal controls RESULTS: In Northern blot analysis and In situ hybridization, PlGF2 mRNA (1.7 kb) band was identified and showed significant decrease in density in preeclamptic placentas compared to that of normal controls. PlGF mRNA was mainly expressed in the syncytial membrane of villous trophoblast, and in the perivascular tissue surrounding the vasculature of stem villi. CONCLUSION: Decreased levels of PlGF mRNA in preeclamptic placentas could have some unfavorable influences on trophoblast and endothelial function, thereby may play a role to the pathogenesis of preeclampsia.

PURPOSE: We evaluated the usefulness of the cementless stem in treating hip fracture patients older than 70. MATERIALS AND METHODS: We studied elderly osteoporotic hip fractures in the neck and intertrochanter area who had received hip arthroplasty with over 2 years of follow up period. Among those, we analyzed the clinical and radiological results of hip arthroplasty with cemented stem (group 1) and hip arthroplasty with cementless stem (group 2). Each group was consists of fifty hips. RESULTS: The mean age at surgery was 75 years and mean follow-up period was 40 months (minimum 24 months). The admission period was 28.68+/-8.8 days for group 1 and 28.05+/-8.7 days for group 2 (p>0.05) and the average operation time was 87+/-21.2 minutes, and 80+/-17 minutes (p>0.05) and the total blood loss was 611+/-141.3 cc and 557+/-120.5 cc (p>0.05) respectively. There was no statistically significant difference in all aspects. One case of pulmonary embolism occurred in group 1. Stem loosening was not observed in both groups at the last follow-up radiologic study. CONCLUSION: The hip arthroplasty with cementless stem for the osteoporotic hip fractures showed a competent results clinically and radiologically in short term follow up as compared with the cemented stem.

Townes-Brocks syndrome is an uncommon autosomal dominant condition first described by Townes and Brocks in 1972. We experienced a newborn female who presented with clinical findings of Townes-Brocks syndrome in an otherwise unaffected family. The patient showed the full spectrum of anomalies including anterior placed anus, triphalangeal thumb, preaxial polydactyly, pre-auricular tags, microtia without opening, sensorineural hearing loss and unilateral renal agenesis.

OBJECTIVE: On the magnetic resonance image (MRI) of the infiltrating brain tumor, enhancement is usually higher in malignant tumor than in benign tumor, and tumor cells can invade into the peritumoral area without definite enhancement. In various pathological conditions, the blood brain barrier (BBB) becomes changed to pathological condition, allowing various materials extravasating into the interstitial space, and degree of enhancement is depend on the pathology. Authors performed dynamic MRI on enhancing and surrounding edematous area in order to evaluate the degrees of opening of BBB, to differentiate tumor from non-tumorous condition, and to determine its relationship with the recurrence of the tumor. METHODS: Dynamic MRI was performed in 25 patients. Dynamic scans were done every 15 seconds after administration of Gd-DTPA on the enhancing and surrounding area for maximum 300 seconds, and the patterns of enhancement were analysed. The enhancement curve with initial steep increase followed by slow decrease was defined as "N pattern", those with initial steep increase followed by additional slow increase as "T pattern", and those with initial steep increase followed by plateau as "E pattern". Histopathological findings were compared with the dynamic scan. RESULTS: The graphs taken from enhancing area showed "T pattern" regardless of pathology. In the surrounding area, "T pattern" was noticed in the malignant tumors, but "E pattern" or "N pattern" was noted in low-grade or benign tumors and non-tumorous condition. "T pattern" in the surrounding area was related to the malignancy with tumor cell infiltration and recurrence. CONCLUSION: The results suggest that the malignant tumor infiltration changes the condition of BBB enough to extravasate the Gd-DTPA. Enhancement pattern in the surrounding edematous area may be a useful information to differentiate the malignant glioma with the low-grade and benign tumors or other non-tumorous conditions.

Venous anomalies, including portal vein thrombosis (PVT) and prior portosystemic shunts, are not uncommon in orthotopic liver transplantation (OLT) and require vascular reconstruction. PVT has been considered as a contraindication to OLT because of surgical complexity and increased postoperative morbidity and mortailty rates. Postoperative chylous ascites occur following disruption of abdominal lymphatics after retroperitoneal dissection. Chyloperitoeum after OLT is very rare. We report a case of piggyback OLT in a cirrhotic patient with portal vein thrombosis. A thromboendarterectomy was attempted first, and a venous jump graft was required between the donor portal vein and the infrapancreatic superior mesenteric vein. An aortic conduit was used for the hepatic arterial reconstruction. Retroperitoneal dissection was inevitable. Chylous ascites developed after the operation and were managed successfully with a low-at diet. In conclusion, we suggest that the presence of PVT is not a contraindication for OLT. Chylous ascites are rare after OLT, and the treatment of choice is a conservative one based on diet control.
