PURPOSE: To evaluate the characteristic CT findings of neuroblastoma, we studied neurobalstomas. METHODS AND MATERIALS: We analysed CT findings of available 25 cases among pathologically proved 51 neurobalstomas from Jan. 1983 to Sept. 1990. RESULTS: The most frequent site of origin is adrenl gland (40%) and the second is retroperitoneum (32%) and the third ismediastinum (16%). Characteristic CT findings are as follows:Calcifications within the tumor is detected in 86% of abdominal neuroblastomas and 50% of mediastinal origin. Hemorrhagic and necrotic changes within the tumor is noted at 86% in the tumor of abdominal origin and 25% in mediastinal neuroblastomas. Contrast enhanced study showed frequently septated enhanced appearance with/without solid contrast enhancement. Encasements of major great vessels such as aorta and IVC with/without displacement by metastatic lymphnodes or tumor are frequently seen in 90% of abdominal neuroblastomas. Multiple lymphadenopathy are detected in 95% of abdominal neurobalstomas and 25% of mediastinal neuroblastomas. The most common organ of contiguous direct invasion is kidney in 6 cases and the next one is liver but intraspinal canal invasion is also noted in 2 cases. CONCLUSION: We concluded that diagnosis of neuroblastoma would be easily obtained in masses of pediatric group from recognition of above characteristic findings.

There has been numerous experimental liver transplantation models in the rodent : orthotopic versus hetrerotopic; whole liver versus partial liver; microvascular suture versus cuff method in technical aspects. Several simplified modifications were introduced for experimental liver transplantation for improving animal-survival rate. Liver transplantation without arterial reconstruction, the cuff tchnique or stent method were the examples of simplifing modification. In practice, complications related to biliary reconstruction are frequent causes of intraabdominal infection in our rat liver transplantation. Here we propose using simple liver transplantation model of partial heterotopic liver transplantation without artery and bile duct reconstruction in the studies which need only observation of immediate graft survival or very short-term follow-up. Here we examined the serial histologic changes of auxiliary liver grafts without biliary reconstruction during short period after transplantation. Until 7 days of transplantation, bile duct proliferation was confined in the portal area of grafts and did not distort the lobular structure. Early graft-survival and rapid immunologic response might be evaluated by this easy transplantation model.

Myotonic dystrophy is the most common systemic disease causing myotonia. We report the case of respiratory failure in a patient with myotonic dystrophy after laparoscopic cholecystectomy. We carried out neurologic testing, electromyography and DNA testing in this patient and electromyography in the family of the patient. Through electromyography and DNA testing, this patient was diagnosed with myotonic dystrophy type I. Myotonic dystrophy is characterized by gradual decline of muscle tone and myotonia. It is important that this disease be excluded through preoperative history taking, physical examination and family history taking.

Freibergs disease is avascular necrosis of the second or third metatarsal bone. Since 1914, numerous causes and treatments have been proposed but no definite single cause and treatment method were developed. The simple method, joint debridement could not recover the pathophysiologic condition of Freibergs disease and the destructive method, metatarsal head resection and prosthetic replacement arthroplasty had many postoperative problems. Recently, dorsiflexion osteotomy, which was described by Gauthier and Elbaz for the first time, and joint debridement and reshaping of the metatarsal head, which was described by Mann, were very effective method to manage Freibergs disease. This paper was aimed to evaluate the result of joint debridement and reshaping of the metatarsal head which were relatively simple, less destructive and safe method in treatment of the advanced Freibergs disease. We treated 7 cases of Freibergs disease from August 1993 to March 1997. The results were as follows: 1. All the patients of the last follow-up improved pain. 2. The passive range of motion was increased from 39.1 preoperatively to 57.6 postoperatively. 3. Follow-up X-rays showed no loose body and further metatarsal head destruction. The above results suggested that the joint debridement and reshaping of metatarsal head provided good result in the treatment of advanced Freibergs disease.
