Limb salvage operation in primary malignant bone tumors is increasing recently, according to the improvement of diagnostic methods, surgical technique and adjuvant chemotherapy. The purpose of this study is to obtain the interim results of survival rate and the functional grade of the limb in primary malignant bone tumors treated by limb salvage operation. Between 1985 to 1993, 63 primary malignant bone tumors treated by limb salvage operations. Tumor prosthesis arthroplasty was performed in 49 patients, resection arthrodesis in 9 patients, and IM nailing with cement molding in 5 patients. Autoclave autograft was combined in 2 patients. Adjuvant chemotherapy and postoperative radiotherapy were performed in selected patients. The average follow-up period was 50 months(ranged 12 months to 116 months). In the cases of osteosarcoma, estimated survival rate was 61.9% based on Kaplan-Meier survival plot. In the parosteal sarcoma, the survival rate was 87.5% and 80% in chondrosarcoma patients. According to functional grading by Enneking, 66% was excellent, 20% was good, 11% was fair and one patients was poor. Complications occurred in 16 patients:wound infection was developed in 6 patients, local recurrence in 4, peroneal nerve palsy in 2 patients and femoral stem loosening in 2 patients. Fracture in resection arthrodesis and pulmonary metastasis were also occurred. Reoperation was performed in 10 patients at average 31 months after initial operation. Revision tumor persthesis arthroplasty was performed in one patient due to local recurrence and in 2 patients due to femoral stem loosening. Three amputations were done due to recurrence of tumor. IM nailing with cement molding was performed in one patient due to deep infection and repeated arthrodesis was done in a fracture patients. Scheduled custom-made tumor prosthesis arthroplasty was performed within a year in 2 patients treated with IM nailing with cement molding. In conclusion, with the careful preoperative assessment, adjuvant chemotherapy and skillful surgical technique, limb salvage operation would provide the primary malignant bone tumor patients for longer survival and better quality of life.

Neuronal migrational disorders of the brain represent abnormalities in the formation of the neocortex caused by faulty migration of the subependymal neuroblasts. The neuroblasts normally migrate between the sixth and 15th gestational week and in doing so form the six-layered neocortex. When the migration does not occur in a normal fashion the resultant brain anomalies include lissencephaly, pachygyria, schizencephaly, hemimegalencephaly, heterotopia, and polymicrogyria. Neuronal heterotopia is a collection of nerve cells in abnormal locations as a result of arrest of their radial migration, improper formation, or destruction of the radial glial fiber. We reported a case of neuronal heterotopia with brief review of related literatures.

Summary: Forty three cases of the pigmentary degeneration of the retina (P.D.R.) visited N.M.C. from Nov. 1958 to Sept. 1964 were analysed clinically in regard to various factors which were also based on a review of litrature. The results of the study include following findings. 1. Among 43 cases, retinitis pigmentosa binocular were the largest (25), Laurens-Moon-Biedl Syndrome (3), Macular Involvement (2), Retinitis Pigmentosa sine pigment (2), Retinitis Pigmentosa monocular (1). 2. 6-15 years group is exceedingly largest in regard to the age of the onset. 3. Male is exceedingly prevalent (32) than female(11). 4. 51-60 years old group is the largest in regard to the duration of illness. 5. The known cases through the family history was only 10. The mode of heredity seems to be rather prevalent as recessive than dominant but the group is too small to make a definite decision. 6. Pigmentary deposits in the retina was the largest in regard to the ophthalmoscopic findings. Coneen tric contraction is the the largest as to the visual field changes. 7. Cataract is the largest (24 cases), myopia (12 cases) in the next, as to the complications. 8. As to the symptoms of the Laurens-Moon-Biedl Syndrome, Obecity, Retinitis Pigmentosa, and Mental retardation is found in all cases, but Polydactly in 2 cases, and Genital dystrophy in 1 case. None of cases were specifically related to this disease through the family history.

Sertoli-Leydig cell tumors of the ovary are rare, accounting for no more than 0.5% of all ovarian neoplasms. These tumors occur predominantly in women 10 to 30 years of age. Heterologous elements are found in over 20% of the moderately and poorly differentiated Sertoli- Leydig cell tumors. The most common element is gastrointestinal mucin-secreting epithelium, found in approximately 20% of all cases. Approximately 4% of Sertoli-Leydig cell tumors contain immature skeletal muscle and/or cartilaginous elements. The origin of these neoplasms is regarded as neometaplasia of the mesodermal neoplastic element. While the degree of differentiation of Sertoli-Leydig cell tumors is probably of greater importance in determining prognosis than the presence of heterologous components, recent evidence does point to an unfavorable effect on clinical outcome when heterologous mesenchymal components such as cartilage and striated muscle are present. We experienced two cases of ovarian heterologous Sertoli-Leydig cell tumors with gastrointestinal type epithelium and striated skeletal muscle in 20 and 21 year-old females, respectively. One case involved a patient who had complained of amenorrhea for 3 years while the other case involved a patient who had complained of left lower abdominal tenderness and amenorrhea for one and one half years. It was determined by ultrasonography of the pelvis that the two patients suffered from right and left ovarian masses. Both patients underwent adnexectomy. These tumors were large with partly solid and partly cystic areas. Based on light microscopic examination one case was classified as an intermediate Sertoli-Leydig cell tumor with heterologous gastrointestinal type epithelium, while the other case was classified as a poorly differentiated Sertoli-Leydig cell tumor with heterologous striated skeletal muscle.

BACKGROUND: This study was performed to evaluate our experience on laparoscopic appendectomy. METHODS: Retrospective analysis was performed on 2,856 patients who had been operated by laparoscopic appendectomy under diagnosis of acute appendicitis at the Sung-Ae Hospital and Kwang-Myoung Sung-Ae Hospital from October 1991 to July 1998. RESULTS: Among 2,856 patients who had undergone laparoscopic appendectomy,2,379 patients (83.3%) were operated due to simple acute appendicitis, 275 patients (9.6%) due to perforated appendicitis. Operation time was 44.6 minutes for simple acute appendicitis and 60.3 minutes for perforated appendicitis. In perforated appendicitis, intra-peritoneal irrigation and drain insertion was performed. The length of hospital stay in patient with simple acute appendicitis was 3.7 days (5.82 days in conventional appendectomy) and patients with perfotrated appendicitis was 6.1 days (9.91 days in conventional appen-dectomy). Complications such as wound infection, intra-abdomen abscess, trocar site bleeding, subcutaneous emphysema developed in 43 (1.5%) patients (79/1,947, 4.5% in conventional appendectomy). In 202 (7.1%) patients, appendix was normal, but another diseases were detected, including acute pelvic inflammation, ovarian cyst, mesenteric lymphadenitis, enteritis, diverticulitis in order. CONCLUSION: Overall complication rate was lower in laparoscopic appendectomy compared with conventional appendectomy and the length of hospitalization of laparoscopic appendectomy was shorter. When the acute appendicitis is suspected, especially in the reproductive women, the laparoscopic approach would be better diagnostic and therapeutic value than conventional method. Therefore laparoscopic appendectomy would be replaced with conventional appendectomy.

Plexiform neurofibroma is considered a pathognomic of Von Recklinghousen's disease, which involves the deep and large nerve trunk. These are large irregular nerve fascicles which result from an increase in endoneural matrix within individual nerve facicles, without an increased number of nerve fibers. We experenced a case of Von Recklinghausen's disease in a 24 year-old male who had variable cutaneous skeletal, and CNS lesions. He presented multiple neurofibromas, cafe-au-lait spots, and axillary freckles as common cutaneous lesions of NF-I and giant pigmentation, sacral hypertrichosis, and plexiform neurofibroma as unusual cutaneous lesions. Also he had a scoliosis, bowing deformity of the humerous and wedging deformity of the body of the 5th cervical spine as a skeletal manifestation and cortical calcification in the occipital area as a CNS manifestation.

With the increase of motor accident, the rate of popliteal artery injury is increased, As the injuries are critical, early diagnosis and prompt treatment can save the limb. 27 cases of popliteal artery injury patients were reviewed and the result was as follows ; l. Amputation rate was 11%, as 3 out of 27 cases failed. There was no correlation between ischemic time and the rate of amputation. 2. Complete resection of all injured portion of vessel and reconstruction of patency through interposed saphenous vein graft was often indicated to avoid tension at the anastomosis site. 3. The rate of fasciotomy was positively correlated with the ischemic time. 4. Medial approach is preferred to posterior approach, since it makes proximal extension of exploration possible, and decrease the incidence of joint contracture. 5. Complications noted are wound infection, systemic sepsis and venous stasis, but they could be treated with proper management. However, nerve deficit due to associated nerve injuries was resist to treatment.
