There are many difficult problems and various methods in the treatment of difficult fractures of the femur. We reviewed the records of twelve patients who had been managed with circular external fixation using the llizarov apparatus for difficult fractures of the femur at Keimyung University. Dongsan rnedical center from October 1993 to April l996. There were ten males and two females with an average age of 42 years (range, 16-74 years). Si.x of twelve patients were severely comminuted supracondylar and intercondylar fractures of the femur associated with severe soft tissue injury (including four open fractures). These patients were treated initially by closed reduction with Ilizarov external fixator and followed by compression-distraction techniques. Four of the remaining six ptients developed infected non-unions after internal fixation of the femur without shortening or bone defect. These infected non-unions were treated by curettage, irrigation and Ilizarov application. After the control of infection, compression - distraction techniques were applied. One of the remaining two patients had severe open comminuted fracture of the supra-intercondyle region of femur associated with diaphyseal segmental bone defect (5cm in length). This patient was treated with closed reduction and internal bone transportation usipg llizarov external fixator. One patient with varus deformity (20 degree) was treated by correction of the deformity and simple compression technique. In three patients, additional autogenous cancellous iliac bone graft was done. The union of the fracture site was obtained in ten patients and the duration of llizarov external fixation was an average of 10 months (range 6-14 months). We experienced several complications; there were twelve patients of limitation of motion of knee, ten patients of pin tract infection, one patient of fracture site non-union, one patient of re-fracture and one patient of femoral artery injury. We concluded that the Ilizarov external fixation technique is one of the effective methods for the treatment of difficult fractures of the femur in spite of its complexity and high incidence of complications.

The vagina is an infrequent site of primary sarcomas, which are less than 2% of all malignant vaginal neoplasm. The most common malignant mesenchymal tumor of the vagina is rhabdomyosarcoma, but leiomyosarcoma is rare type tumor of the vagina. Microscopically, spinle cells with pleomorphic nuclei and mitotic figures were frequently noted, but cross-striations were not found in the tissue. Alpha-smooth muscle actin and desmin were positive, but sarcomeric actin was negative in the tumor cells. The authors report a case of primary leiomyosarcoma of the vagina with brief literature review.

Multilocular cystic renal cell carcinoma appears to be a distinct and rare subtype of renal cell carcinoma with characteristic gross and microscopic features. Multilocular cystic renal cell carcinoma should be separated from multilocular cyst, multilocular cystic nephroma, and renal cell carcinoma with cystic degeneration. We present a case of multilocular cystic renal cell carcinoma. A 61-year-old man presented with right flank pain for 4 years. The computerized tomography revealed multilocular cystic mass in the upper pole of right kidney. The cystic mass measured 4.5x4 cm. The cyst was multilocular and locules not communicated with each other. The solid area was not present. Microscopically, the locules were lined by flat or cuboidal neoplastic clear cells. The clear cells were focally aggregated in the septa. The nephron was not present in the septa.

Epstein-Barr virus (EBV) has been known to be associated with a wide variety of neoplastic conditions including nasopharyngeal carcinoma, Hodgkin's disease, and non-Hodgkin's lymphoma. Recent studies reveal the presence of EBV in certain subtypes of gastric carcinoma in which EBV appears to be pathogenetically related. To evaluate the relationship between EBV and gastric adenocarcinoma, we examined EBV DNA using direct in situ polymerase chain reaction, and expression of p53 protein and bcl-2 protein using immunohistochemical staining method on paraffin embedded tissues. The materials consisted of one hundred twenty-eight gastric adenocarcinomas and twenty benign peptic ulcers. EBV DNA was detected in 14 of 128 gastric adenocarcinomas (10.9%). p53 protein was positive in 10 of 14 EBV positive adenocarcinomas (71.4%) and in 61 of 114 EBV negative adenocarcinomas (53.5%). Bcl-2 protein was positive in 2 of 14 EBV positive adenocarcinomas (14.3%) and in 19 of 114 EBV negative adenocarcinomas (16.7%). The above results indicate that EBV is associated with gastric adenocarcinoma, and p53 protein may play a role in carcinogenesis of EBV in gastric adenocarcinoma.

5.A Study about Reliability of Radioisotope in Diagnosing Varicocele.
Korean Journal of Urology 1990;31(5):707-714
In order to consider the usefulness of radioisotope in diagnosing varicocele, a study was performed on 124 cases. Among them, 74 cases were diagnosed as varicocele, which included 16 cases of subclinical varicocele. Among 74 varicocele patients, 62 cases ( 83.8%) were diagnosed by varicocele index and 59 cases (79.7% ) were diagnosed by static image. A combination of the above two methods allowed 67 cases (90.5 %) to be diagnosed. 21 patients who had a high ligation of internal spermatic vein showed 11 excellent results, 6 good results and 4 poor results. Out of 10 patients with subclinical varicocele, there were 6 excellent results, 3 good results and 1 poor result and 9 patients showed improvement on postoperative semen analysis. There was no significant statistical difference in frequency of the testicular arterial insufficiency between the small varicocele group and the large varicocele group. Also, through scrotogram, it became known that semen analysis proved little help in aiding the diagnose of subclinical varicocele. In conclusion, 'Scrotogram proved very helpful in diagnosis and judging the results of operations of varicocele including subclinical varicocele.

It is important to predict the prognosis of patient with cancer. Well known parameters predicting the prognosis are staged and degree of differentiation. Recently, the prognostic and diagnostic significance of silver-stained nucleolar organizer regions(Ag-NORs) and flow cytometric DNA analysis are introduced. This study aims to detect the diagnostic significance of Ag-NORs in breast lesions, and to correlate the number of Ag-NORs and cellular ploidies in breast carcinoma. In addition, the existence of heterogeneity according to the sample in the same patient is studied Sixty six paraffin blocks(two primary lesions and the two metastatic lymph nodes in 13 patients, and one primary lesion and one metastatic lymph node I 10 patients) of breast carcinoma, 30 paraffin blocks of fibroadenoma and 23 paraffin blocks of normal breast are studied. The numbe of Ag-NORs increase from normal breast(mean 1.45) through fibroadenoma(mean 1.60) to carcinoma(mean 2.43). It was significantly different between each lsions(P<0.0005). The number of Ag-NORs increased in the aneuploidy carcinoma than that in the euploidy one(P<0.05). But, there was difference between the number of Ag-NORs and DNA index according to the sample area in the same patient with carcinoma. In conclusion, the number of Ag-NORs is diagnostically significant in breast lesions and is correlated with cellular ploidies in breast carcinoma. In addition, Ag-NORs and cellular ploidies are heterogenous in the same patient.

Malignant struma ovarii is a rare tumor of the ovary. This can be diagnosed by histologically when carcinomas of the thyroid gland are excluded. We present a case of malignant struma ovarii arising from cystic teratoma. A 42-year-old female was admitted for evaluation of lower abdominal mass. Hysterectomy and both adnexectomy were performed on the basis of a clinical impression of uterine leiomyoma and an ovarian mass. The uterus revealed intramural leiomyoma, measuring 8 cm in diameter. Ovarian mass was predominantly cystic and partly solid. Microscopically, thyroid tissue with papillary structures were found in the solid area Papillae were complex, branching and randomly oriented. These papillae were infiltrated in the adjacent fibrous capsule, Clinical evidence of a primary thyroid carcinoma was not found.

The Journal of the Korean Orthopaedic Association 2004;39(5):563-565
This paper present a rare case of a Type III Monteggia equivalent fracture with an ipsilateral distal radial epiphyseal (Salter-Harris type II) and an ulnar metaphyseal fracture in a child. An 8-year-old boy sustained a closed bipolar fracture of his forearm after a fall from a height. The closed reduction was unsuccessful. Therefore, an open reduction and plate fixation was performed for a diaphyseal fracture of the ulna, and the unstable radial fractures and the distal ulnar metaphyseal fracture were treated with a closed reduction and internal fixation using Kirschner wires (K-wires). Two years after surgery, the joint motion including the forearm, wrist and elbow were completely normal. Radiologically, the bone was well united without any residual deformity.

The authors analysed statically 420 Cases of the ocular trauma among 35,460 patients who visited to the emergency department, from Jul. 1995 to Jun. 1996. Ocular trauma is one of the commonest causes of eye diseases and blindness, but its patterns and incidences are variable according to the environment. A large number of patients can be readily treated in the emergency department. Prevention is, of course, the best management, but when an ocular injury occurs, proper emergency treatment can often prevent permanent damage.
