Advancement of imaging and surgical technique makes the internal hemipelvectomy one of the routine procedures of pelvis sarcoma. However, optimal reconstructive option for skeletal defect is still controversial. Pasteurized autogenous bone-total hip composite is a biologic method and its anatomical appropriateness gives good indication for selected cases. Nevertheless, in case of complication such as infection or mechanical breakage, removal of hardware including graft is inevitable. In those cases, marked limb length discrepancy induce marked functional deficit. To overcome this problem, the authors report 1 case, refining previous technique, saving the femoral head and reinsertion of osteoarticularly pasteurized host bone.

Small bowel malignancy consists 1~2 % of overall gastrointestinal tract cancer and leiomyosarcomas of small intestine are 10~20% of small bowel malignancy. Small bowel leiomyosarcomas are rare in incidence and have no specific symptoms, signs or definite radiologic findings, so it is not easy to diagnose at early stage of disease. They are found occasionally by unknown origined gastrointestinal bleeding, abdominal pain, intestinal obstruction, perforation and palpable mass, and diagnosed mostly by operation. Recently annual case reports are increasing trend in Korea. We experienced two cases of small bowel leiomyosarcoma which was diagnosed finally by pathologic findings, so we report them With literatural review.

This experiment was conducted out to investigate the effect of plant growth regulators on callus and shoot formation. The callus formation was effective on 1/2 MS medium containing 2,4-D, while shoot formation was suppressed. Shoot formation and differentiation were the highest in combination 0.1 mg/L of IAA and 0.1 mg/L of BA. The polarity of explants was investigated from cotyledon, which excised 20% of each basal and terminal parts. Formation of shoot was induced from excised ends of the basal part. In excised ends of the basal part, callus was induced vigorously and shoots were produced lately. Root induction was easily achieved in 1/3 MS medium from the adventitious shoot and more than 90% of regenerated plantlets acclimatized successfully and flowered normally.

Meniscal allograft transplantation (MAT) is an accepted treatment for the symptomatic postmeniscectomized knee in younger patients. However, the likelihood of a successful outcome is reduced by various complications. One of the complications after MAT is manifested as grafted meniscal tear. However, a bucket handle meniscal tear (BHMT) following MAT is an uncommon complication and furthermore a BHMT after revisional MAT (RMAT) is a extremely rare complication. We encountered a case of BHMT after RMAT in a lateral meniscus. Retrospectively reviewing the case, we could assume the cause, which would be helpful to prevent the complication in further MAT procedures.

The purpose of this study was carried out to investigate the effects of plant growth regulators on in vitro propagation of Liliem cernum Komarov. Small bulblets were poliferated from callus explants after 2 weeks and leaf, root and bulb were formed after 4 weeks culture. Leaf differentiation was promoted vigorously by the combination of TDZ 0.1 mg/L and NAA 0.01 mg/L(87.5%). The rate of root differentiation was the greatest at BA 0.2 mg/L alone(81.8%). The rate of callus formation was the high in medium containing TDZ. The number of bulblets and leaves formed in bulb scales was the greatest at TDZ 0.1 mg/L(5.7). Also, the longest length of total length, leaf and root length were in Zeatin 1.0 mg/L + NAA 0.1 mg/L(10.5 cm). However the longest bulblet was in TDZ 0.1 mg/L(1.4 cm).

Purpose: We evaluated the complications of allograft reconstruction after a bone tumor resection, and reviewed literatures to overcome such complications. Materials and Methods: We retrospectively reviewed clinical records and radiographs of fifteen patients in whom reconstruction with allograft after bone tumor resection. Results: Eight patients were men and seven were women with a mean age of 27.1 years (1-56 years) and a mean follow-up period of 89.5 months (33-165 months). All postoperative complications related to the allograft were recorded. Twenty patients (80.0%) obtained a radiologic bony union at a mean of 8.35 months (4-12 months). The mean Musculoskeletal Tumor Society score was 73.5% (46.6-93.0%). Nine patients (60.0%) experienced one event and 3 (20.0%) patients experienced multiple events during the follow-up period. Recorded events were infection (3), fracture (2), nonunion (2), limb length discrepancy (2) and varus deformity (2). The mean event free survival period was 60.8 months (6-144 months). The mean allograft survival period was 80.2 months and the 5 year survival rate of the allografts was 83.0%. Conclusion: In order to overcome complications, the combination of an allograft and vascularized fibular graft is highly recommended. In the near future, the tissue engineering technique, the application of the stem cell and PRP, could reduce the complication of allograft such as resorption and nonunion.

Fibroadenoma are one of the most common benign tumors of the breast in young women. Fibroadenoma may be associated with fibrocystic change, proliferative epithelial changes, and extremely rarely with carcinoma. We report here two cases of malignancy arising from a breast fibroadenoma. The patients were 19 and 51 years old and presented with a lump of recent onset. A 19-year-old female patient was diagnosed with mass excision at another hospital, and re-excision was performed at the hospital. Ultrasonography and cytologic examination revealed fibroadenoma and malignancy in a 51-year-old female patient, who was treated with wide excision. The pathological report of the two cases was revealed as DCIS in a fibroadenoma. Because carcinoma arising within a fibroadenoma is so rare, there are few reports of its characteristics or guidelines for treatment. Careful analysis of the unusual carcinoma arising within a fibroadenoma of the breast led to appropriate diagnosis and treatment of various types of lesions. Herein, we report two cases of DCIS arising within a fibroadenoma of the breast and provide a review of the literature.

Purpose: Because of the anatomical characteristics, it is difficult to perform radical operation in spinal tumor. Numerous operations on primary and metastatic spinal tumor have been performed and among those total en bloc spondylectomy has produced decent clinical result. Clinical and radiological results have been analyzed based on five total en bloc spondylectomy on primary and metastatic spinal tumor. Materials and Methods: Patients included in this study were one with primary and four with metastatic spinal tumors, from June 1997 to January 2006. Two of the four were originated form kidney. One was from breast and the other one was not identified. McAfee's 4 point scale, VAS and Frankel's classification have been used as clinical assessment of pain and neurological symptoms. Clinical assessment have been conducted for every 3 months after operation including local recurrence, bone union and complications. Results: Assessment of pain decreased from average of 3 before operation to 1.6 after operation in McAfee's scale and VAS decreased from average of 9.2 to 1.6. Neurological deficit after operation improved from C to D in Frankel's category. Local recurrence has been detected on metastatic adenocarcinoma of L4 during follow up. Conclusion: Total en bloc spondylectomy is evidently useful operational method for primary and metastatic spinal tumor since it completely decompresses spinal nerves, decreases axial pain immediately and improves the quality of remaining life.

Reflex sympathetic dystrophy is an important clinical entity that is characterized by excessive or prolonged pain, vasomotor and other autonomic disturbances, delayed recovery of function, and trophic changes. This syndrome is among the most frequently encountered problems in clinical medicine, and proper diagnosis and therapy are critical. Accidental or surgical trauma or one of a variety of disease states may become a precipitating factor. Proper recognition and treatment result in rapid elimination of symptoms and complete recovery. A 56-years old male accidented total amputation of the proxomal part of the left index finger in May, 1996. Emergently, complete replantation procedure was successfully performed in the department of reconstructive surgery, medical center, Korea University. Afterward, he began to suffer from uncontrolled, prolonged pain in left index finger, proximally spreading pain to the left upper extremity and limited joint movement of the left shoulder. Although many treatments were used for this syndrom, not all of them were effective. Furthermore, the treatments which proved effective had detrimental side effects. However, thoracoscopic left thoracic sympathectomy was performed in our department. This therapy successfully relieved the pain and improved shoulder joint movement.
