We performed this study to evaluate the therapeutic responses of bone marrow transplantation and immunosuppressive therapy for aplastic anemia in 103 cases (68 severe and 35 moderate). Among them, 15 cases with severe aplastic anemia having HLA-identical sibling donor underwent bone marrow transplantation, and cases(53 severe and 35 moderate cases)without available HLA-identical sibling donor had received immunosuppressive therapy using antilymphocye globulin and cyclosporin-A. The results were as follows; 1) For cases given bone marrow transplantation, successful engraftment was accomplished in all cases, but 2 cases showed rejection and 1 case died of thrombotic thrombocytopenic purpura (TTP), resulting 80% disease-free survival rate. acute graft-versus-host disease above grade II was noted in 2 cases and chronic graft-versus host disease was seen in other 2 cases. The most common pathogenic organism in post-transplantation infection was Herpes zoster (6 cases), and one each cases of Herpes simplex, candidiasis, measles and hemorrhagic cystitis developed. 2) Among 88 cases of receiving immunsouppressive therapy, complete response was seen in 26 cases (29.5%) and partial respones in 37 cases (42.0%), resulting 71.6% of overall response rate and recurrence rate was 19.5% (12 cases). In 53 severe cases, complete response was seen in 9 cases (17.0%) and partial response in 25 cases (47.2%), resulting 64.2% of overall response rate. In 35 moderate cases, complete response was seen in 17 cases (48.6%) and partial response in 12 cases(34.3%), overall response rate was 82.9%. All initial responses were seen within 6 months post-treatment period, and the time interval to initial response was 8 to 162 days (median; 53 days). There was no sex difference concerning response rate, however, partial response was predominant in male and more complete response in female. The complications of immunosuppressive therapy were thrombocytopenia (93.2%), fever (67.7%), hypertension (50.0%), skin eruption (45.8%), gingivitis (17.0%). In conclusion, our date suggest that bone marrow transplantation is preferred initial treatment modality to immunosuppressive therapy in severe aplastic anemia patient with HLA-identical sibling donor, and immunosuppression is a satisfactory alternative therapy for children with severe aplastic anemia in the absence of HLA-identical sibling and for whom with moderate aplastic anemia.

The "flosting knee" is the term applied to the flail knee joint segment resulting from a fracture of the shaft of adiacent metanhysis of the ipsilateralfemur and tibia. The various methods of treatment of the "floating knee" were adapted by many authors according to degree of the comminution, degree of the soft tissue injury, general condition state of the fracture. Authors experienced the floating knee in 52 cases on 51 patients who were treated at Soon Chun Hyang University Hospital in the period of 4 years and 5 months from January 1985 to June 1989 and among them, 45 cases were treated by operative method and 7 cases by conservative methods at least one of the femur and tibia, The results were as follews;1. Floating Knee occured six times more in male and the peak age was third and fourth decades. 2. The most common cause of fractures was traffie aecident and there was difficulty in diagnosis of ligamentous disruption of the ipsilateral knee. 3. The common fracture site were middle one third and the most common fracture shape was comminuted in both femur and tibia. 4. A good or excellent functional result was aohieved in treated with open reduction and rigid fixation of both fracture and there were no significant difference in group of the internal fixation of both femur and tibia. 5. Intramedullary nailing on the femur and plate fixation on the tibia provided rigid fixation of fracture and the it made possible early joint motion exercise and ambulation and the average healing time of fracuture was much shortened. 6. The most common concomitant injury were soft tissue injury and delayed or nonuion and osteomyelitis were developed more frequently in the plate and screw fixation group of the open fracture.

Schizencephaly, first described by Yakovlev and Wadsworth in 1946, is a rare congenital anomaly characterized by gray matter-lined clefts that extend through the entire cerebral hemisphere, from the ependymal lining of the lateral ventricle to the subarachnoid space. Clinically, patients with schizencephaly present motor dysfunction such as hemiparesis, seizures, and variable developmental delay. Absence of septum pellucidum, gray matter heterotopia, polymicrogyria, and hypoplasia of optic nerves were also frequently found to be associated with schizencephaly. We experienced a case of open-lip schizencephaly in a one-day-old male infant with wide, tense fontanel, which was confirmed by MRI.

Four newborn infants with hyperbilirubinemia, caused by ABO blood group incompatibility, were treated with high-dose intravenous immune globulin(IVIG). As soon as the diagnosis was clinically suspected, these infants received conventional treatment including phototherapy and were monitored closely for bilirubin levels. When bilirubin concentrations reached the risk point in spite of phototherapy, IVIG was given at a dose of 1g/kg for 6 hours. In all cases, bilirubin levels declined within 12 hours after LVIG therapy, and to rebound effect was seen, No side effects of IVIG treatment were observed. We suggest that high-dose IVIG therapy may be useful in the treatment of hyperbilirubinemia due to ABO incompatibility, and reduce the need for exchange transfusion.

Between 1986 and 1990, four children with recurrent CNS leukemia who had previous CNS prophylaxis therapy were treated with intermittent central nervous system irradiation and intrathecal chemotherapy (IIIC). There was no isolated CNS recurrence. One patient died form bone marrow relapse. Three patients are alive without evidence of disease for 3E3/12 year to 3E6/12 year after the diagnosis of recurrence of CNS leukemia. This experience suggests that IIIC may be an effective treatment for preventing the recurrence of CNS leukemia without any serious side effects.

Transesophageal echocardiography(TEE) is a new acoustic window to the cardiac structures and great vessels via retrocardiac esophagus. Because of the close relation between the esophagus and the heart, higher transducer frequencies can be applied, therefore leading to improved resolution and more accurate images than transthoracic echocardiography. We describe our experience with the first 353 awake patients. The procedure was well tolerated by the patients and associated with no major complications, within examination 10 to 20 minutes. Clinical diseases which appear to be suited for TEE includes 1) evaluation of native valve diseases, particulary mitral valve, pathologic valvular abnormalities and color Doppler regurgitant flows ; 2) assesment of prosthetic heart valves to better define malfunction and important pathologic associations ; 3) congenital heart disease, particularly atrial septal defect ; 4) endocarditis and detection of vegetations and complications ; 5) detection of thrombus and tumors, size, location, morphology, stalk ; and 6) aortic pathology including atherosclerosis, aneurysm and dissection. We conclude that transesophageal echocardiography is a new imaging technique that is rapidly evolving into a major tool for general cardiac imaging in a variety pathologic conditions and is a safe and useful tool in patients. Future advances in probe technology will continue to expand its applications.

PURPOSE: This study was performed to evaluate the effect of aspiration thrombectomy for the treatment of ileofemoral deep vein thrombosis. METHODS: We reviewed the records of sixty-two patients who were treated with catheter-directed thrombolysis (CDT) at our institution between November 2001 and October 2007. The patients were divided into two groups: those who were treated by CDT with aspiration thrombectomy (AT) (the aspiration group; 33 patients) or those who were treated with using CDT alone (the CDT alone group; 29 patients). The obtained data included the demographics, the procedural details, the periprocedural evaluation and the thrombus resolution. RESULTS: The treatment time with using CDT only was 40.93+/-15.59 hours compared with 23.18+/-8.22 hours with using AT (P<0.001). The mean dose of urokinase with using CDT only was 2.48+/-0.82 million IU as compared with 1.60+/-0.54 million IU with using AT (P<0.001). The use of AT did not improve the overall lytic success (P=0.084), but more patients had complete thrombus resolution (13 vs. 22 patients, respectively). There was no difference in symptom improvement or the long term patency rate between the two groups. There was no major morbidity or mortality. The prophylactic IVC filters were inserted in 31 patients and entrapped thrombi were founded in 3 patients of the aspiration group. Evidence of venous reflux was identified in the CDT only group (3 patients; 10.4%). CONCLUSION: These results suggest that the use of AT offers more effective thrombus removal in less time and with using a lower dose of thrombolytic agents. When performing AT treatment, prophylactic IVC filter insertion should be considered for preventing floating thrombi.

To evaluate the implication of vascular factor in normal tension glaucoma, authors performed color doppler imaging[CDI] for ophthalmic artery, central retinal artery and posterior ciliary artery in 21 eyes of 12 patients in normal tension glaucoma and 16 eyes of 11 patients in normal control group. We compared peak-systolic velocity[PSV], end-diastolic velocity[EDV], mean velocity[MV], resistance index[RI] and pulsatile index[PI] between the two groups. We evaluate the difference in parameters according to age, sex, systolic and diastolic blood pressure, past history of diabetes and hypertension, cup-disc ratio and visual field change. In normal tension glaucoma group, PSV, EDV and MV of ophthalmic artery and central retinal artery were significantly decreased and pulsatile index was significantly increased compared to those of normal group. Resistance index was also increased in normal tension glaucoma group, but statistically not significant. All parameters of posterior ciliary artery had no significant difference between the two groups. Age was related positively to pulsatile index and resistance index of central retianl artery and diastolic blood pressure was related positively to resistance index of ophthalmic artery. Cup-disc ratio was related negatively to PSV and EDV of ophthalmic artery. Above results imply that blood flow velocity decreased by increasing resistance factor in normal tension glaucoma, therefore local vascular factor might be related to the development of the normal tension glaucoma and affected by age, blood pressure and cup-disc ratio change.
