The authors described a case of male schizophrenia who developed myoclonic jerk repeatedly and one episode of convulsive seizure during the treatment of clozapine. According to literatures and reported cases, myoclonic jerks induced in a small amount of clozapine may precede and predict the development of a convulsive seizure. Therefore clinicians have to pay attention to the development of a myoclonic jerk during the administration of clozapine. They may decrease the dosage of clozapine step by step at first in the convulsive state, and observe EEG changes of patients frequently.

With the recent introduction and development of the detachable balloon system, it has become the treatment of choice in the management of carotid cavernous fistulas(CCFs). But, since most delivery systems for embolization of CCF mainly depend on flow guidance for balloon delivery, in cases of small fistula, pseudoaneurysm and arterialized venous collaterals, failure of balloon embolization can occur. To overcome these limitations, the authors designed and used a new versatile, steerable, and flow-guided detachable balloon system by using a Tracker catheter system with silicone or latex balloons. Using this maneuver, we could get successful fistula occlusion in 7 out of 8 patients(silicone balloon). But in one case, we had to occlude the internal carotid artery at the fistula site, proximal and distal cervical portions of the internal carotid artery. This balloon delivery system proved to provide high selectivity for fistula and relatively ease of handing.

In anesthetized cats the effects of lactate-activated muscle spindle upon the group Ia muscular afferent fibers were studied. Laminectomy was done from L5 to Sl spinal cord level. Extracellular recording was done at dorsal root to record the impulse discharge from group Ia muscular afferent fibers. 1) Muscle spindle of Gastrocnemius-Soleus muscle were activated by lactate injection and exhibited increased impulse discharge through group Ia muscular afferent fibers. 2) There was latency of 7-12 seconds before muscle spindle is activated by lactate injection. But the whole response was not dose related. 3) The response pattern after lactate injection was divided into three groups which were excitation, inhibition and inhibition with preceding excitation. 4) Some responses were similar to those of bradykinin, sympathetic stimulation (adrenaline injection) and succinylcholine injection. 5) It was suggested that muscle spindle has characteristics of polymodal receptor which has responses to not only mechanical stimulation but also chemical stimulation.

Intussusception is the most common cause of acquired intestinal obstructions during infancy and early childhood. Barium reduction and pneumoreduction have been sued widely as nonsugical method of treatment in radiologic department. In the past, attempts at barium reduction of intussusception were contraindicated in the presence of frank intestinal obstruction, shock, fever, dehydration, bowel perforation, peritonitis and longstanding symptoms. At present, however, there is no agreement on the contraindications, except for shock, peritonitis and bowel perforation. Especially, there is no consensus regarding its application on patient presenting with sign of frank intestinal obstruction. The authors analyzed the effect of pneumoreduction in the intussusception with sign of frank intestinal obstruction. Pneumoreduction was attempted in 53 cases of intussusception with sign of frank intestinal obstruction. Reduction was successful in 43 cases(81%). The mean fluroscopic time was 15.1 minutes and mean maximal pressure was 121.8mmHg in successful reduction. As complications, two cases of bowel perforation were observed, but could be treated surgically without any significant problem. In conclusion, pneumoreduction is a useful substitute for barium reduction in the management of pediatric intussusception with sign of frank intestinal obstruction.

PURPOSE: Renal transplantation which allows children normal growth and development and a return to normal life. is now proven to be the best modality for children with ESRD Up to Recently, the number of renal transplantations in Asia has rapidly increased and the outcome has also improved. This investigation was planned to estimate the current status of pediatric renal transplantation in Asia and to find the keys for better improvement of outcome in pediatric renal allograft in Asian countries. MATERIAL AND METHODS: The participating countries and institutions for this investigation were China, Hong Kong, India, Indonesia, Japan, Malaysia, Pakistan, Philippines, Singapore, Thailand, Korea, KSPN (Korean Society of Pediatric Nephrology), KONOS (Korean Network for Organ Sharing). RESULTS: Many countries in Asia still do not have a well organized nation wide renal transplantation registration system independently in the pediatric field . So it's very difficult to evaluate the real state of pediatric transplantation among Asian countries. According to the estimation with fragmented data from each countries, in the front running countries of pediatric renal transplantation in Asia, about 40 or more transplants were performed in each country per year and the five year actuarial renal allograft survival was around 80% which is similar to that of western countries. But there were large gaps among the behind groups. CONCLUSION: Vigorous attempts to perform renal transplantation for children especially younger than 5 years old would be encouraged as well as organ donation from brain dead donor and non heart beating cadaveric donor also should be activated to cope effectively with the shortage of living donor supply. Large number of recent reports shows the favorable outcome of pre-emptive renal transplantation, we should make more efforts toward pre-emptive renal transplantation. First of all, in order to improve the outcome and to narrow the gap between Asian countries in pediatric renal transplantation, effective and continuous efforts to establish nationwide pediatric renal transplantation registration program as well as official, nation-to-nation data sharing program should be needed.

PURPOSE: To clarify the chracteristic sonographic features of benign soft tissue tumors and to evaluate the usefulness of sonographic imaging. MATERIALS AND METHODS: We retrospectively reviewed ultrasonographic images of 70 cases in 68 patients with histologically proved benign soft tissue tumors. RESULTS: The tumors included 33 lipomas, 11 hemangiomas. 11 lymphangiomas, 7 neurilemmomas, 4 epidermold cysts, 2 fibromas, 1 mesenchymoma, and 1 myxoma. The SOhographic appearances of the lesions were mainly solid in 53 cases(33 lipomas, 8 hemangiomas, 2 lymphangiomas, 7 neurilemmomas, 2 fibromas and 1 mesenchymoma), mainly cystic in 14 cases(1 hemangioma, 8 lymphangiomas, 4 epidermoid cysts, and 1 myxoma), and mixed in 3 cases(2 hemangiomas and 1 lymphangioma). Although an accurate histologic prediction could not be made in most cases, certain patterns appeared to be characteristic of specific tumor types. 26 cases(78%) of lipoma were seen as lentiform, iso- or hyperechoic, solid mass. Hemangioma had variable appearance and chacteristic calcifications were seen in 3 cases. Unicameral or multiseptated cystic mass with variable thickness of echogenic septa and solid portion was the characteristic finding of lymphangioma. Neurilemmoma showed Iobulated, oval to round, relatively hypoechoic mass with or without internal cystic portion. CONCLUSION: Sonographic evaluation of benign soft tissue tumros is useful in demonstrating the location, size, extent, and internal characteristics of the mass. A relatively confident diagnosis can be made when the characteristic features of the benign soft tissue tumor are present on sonographic imaging.
