Recently there has been decreasing trend of high tibial osteotomy in management of the gonarthrotic patients partly due to recurrence of the symptom and, more importantly, due to the relative success of the total knee joint replacement procedure. But there is still room for the high tibial osteotomy, although it may be 'outdated' procedure, in that younger active patients do well postopera- tively for an enough period of time and that even the older have some gain of pain-relief in early postoperative period. The purpose of this study is to detect the affecting factors of the result of the operation. We reviewed 25 valgus high tibial osteotomies in 23 patients who had medial gonarthrosis and could be followed-up more than 1 year among 32 cases between August 1989 and January 1994. The mean length of follow-up was 30 months(ranged twelve to fifty four months). The results were compared according to modified grading of the HSS score. All cases showed the increase of the score from preop. average 65.2 points to postop. 87.8 points, mainly by the decrease of pain and the increase of functional activity. The severity of degenerative change on the radiographs and the degree of varus seemed to be related with the early clinical results of the operation, but the age was not a major affecting factor. These results could be debatable due to some differences from the others', and long term follow-up would be needed.

The purpose of this study is to compare the effects of the femoral attachment points of the graft and knee flexion angles at the time of graft fixation on stability of posterior cruciate ligament reconstruction. We analyzed the posterior stability of the knee on 23 patients(24 knees) with posterior cruciate ligament injury whose posterior cruciate ligament had been reconstructed arthroscopically and followed for minimum 1 year period at Asan Medical Center from May 1992 to June 1994. The patients were divided into the two groups according to femoral attachment points of the graft and knee flexion angles at the time of graft fixation. The distance from the junction of the intercondylar notch with trochlear groove of the femoral attachment points and knee flexion angles were 11mm and 0°-30° in group A and 7mm and 70°-90° in group B, respectively. 11 knees were included in group A and 13 knees in group B. Posterior stability was determined by difference in posterior tibial translation between the injured and the opposite knee with Telos device. In group A, 5 cases were at the range of 0-2mm, 3 cases 3-5 mm, 3 cases 6-10mm. In group B, 10 cases were at the range of 0-2mm and 3 cases 3-5mm, respectively. Differences in posterior tibial translation on average were 3.6mm and 1.7mm in group A and B, respectively. Conclusively, arthroscopic postrior cruciate ligament reconstruction with femoral attachment point at 7mm from the junction of interconlylar notch with trochlear groove and 70°

Background: We evaluated the efficacy of Dor procedure in patients with ischemic left ventricular dysfunction. Material and Method: Between April 1998 and December 2002, 45 patients underwent the Dor procedure concomitant with coronary artery bypass grafting (CABG). Left ventricular ejection fraction (LVEF) and left ventricular end-diastolic/end-systolic volumes (LVEDV/LVESV) were measured by echocardiography, myocardial SPECT, and cardiac catheterization and angiography performed at the sequence of preoperative, early postoperative, and one year postoperative stage. Result: Cardiopulmonary bypass and aortic clamp times were mean 141+/-64, 69+/-24 minutes, respectively. Intraaortic balloon pump (IABP) therapy was required in 19 patients (42%; 7 preoperatively, 9 intraoperatively, 3 postoperatively). Operative mortality rate was 2.2% (1/45). Postoperative morbidities were low cardiac output syndrome (12), atrial fibrillation (5), acute renal failure (4), and postoperative bleeding (4). Functional class (NYHA) was improved from classes 2.8 to 1.1 (p<0.01). When we compared between the preoperative and early postoperative values, LVEF was improved from 32+/-9% to 52+/-11% (p<0.01). The asynergy portion decreased from 57+/-12% to 22+/-9%, and LVEDV/LVESV indexes improved from 125+/-39 mL/m2, 85+/-30mL/m2 to 66+/-23 mL/m2, 32+/-16 mL/m2 (p<0.01). Although these changes in volumes were relatively preserved at postoperative one year, the left ventricular volumes showed a tendency to increase. Conclusion: After the Dor procedure for ischemic left ventricular dysfunction, LVEF improvement and left ventricular volume reduction were maintained till postoperative one year. The tendency for left ventricular volume to increase at postoperative one year suggested the requirement of strict medical management.

Infection of cattle with bovine leukemia virus (BLV) has been observed and reported worldwide, including in Korea. The onsite identification of infected cattle would help decreasing and eradicating BLV infections on farms. Here, we present a new immunochromatographic assay that employs monoclonal antibodies (MAbs) for the detection of antibodies against BLV in the field. BLV envelope glycoprotein (gp)51 was expressed in E. coli, and MAbs against recombinant BLV gp51 were generated for the development of an immunochromatographic assay to detect BLV antibodies in cattle. The sensitivity and specificity of the assay were determined by comparing these results with those obtained from a standard enzyme linked immunosorbent assay (ELISA). A total of 160 bovine sera were used to evaluate the new immunochromatographic assay. Using ELISA as a reference standard, the relative specificity and sensitivity of this assay were determined to be 94.7% and 98%, respectively. Because of its high sensitivity and specificity, this BLV antibody detection assay would be suitable for the onsite identification of BLV infection in the field.

Terson's syndrome is one of the cerebro-ocular syndrome which entails the findings due to intraocular hemorrhage in association with increased intracranial pressure following subarachnoid hemorrhage. We reported a patient suffering from total blindness after basal ganglia hemorrhage, who was diagnosed as Terson's syndrome and vitrectomy was done. Our patient recovered normal visual acuity after vitrectomy, which fascilitated rehabilitative process. We also performed diffusion tensor tractography to investigate abnormalities of brain related to the visual dysfunction, which revealed decreased orientation and integrity of the right optic radiation. It is important to diagnose Terson's syndrome early because it is one of the cerebro-ocular syndrome which needs early intervention with consideration of the integrity of optic pathway.

BACKGROUND/AIMS: Many studies on infliximab have confirmed its efficacy in the remission induction and even maintenance in refractory and fistulizing Crohn's disease. We report the treatment efficacy of infliximab in Crohn's disease and ulcerative colitis refractory to steroid treatment and the complications of infliximab treatment. METHODS: We performed infliximab administration in 5 cases (3 Crohn's disease, 2 ulcerative colitis) refractory to systemic steroid treatment and 5 cases of Crohn's disease with fistula. Patients received an intravenous infusion of infliximab at 3-5 mg/kg body weight. RESULTS: In 3 cases of refractory Crohn's patients, clinical response and remission induction were obtained in 2 (67%) and 1 cases (33%). After infusion of infliximab, the occlusion of internal fistula could be found in all 2 cases. Two out of 3 cases of anal fistula were completely healed. In two cases of refractory ulcerative colitis, one case who showed clinical manifestation of toxic megacolon had improved and avoided the colectomy, but the other case did not respond to the infusion of infliximab and underwent colon resection. CONCLUSIONS: We found that administration of infliximab is an effective alternative for refractory and fistulizing Crohn's disease but further studies are necessary for refractory ulcerative colitis.

Knowledge of the prevalence of human Toxoplasma gondii infection is required in the Republic of Korea. In this study, we surveyed the seroprevalence of T. gondii infection and analyzed the risk factors associated with seropositivity among residents in 2 administrative districts; Seoul and the island of Jeju-do, which have contrasting epidemiologic characteristics. Sera and blood collected from 2,150 residents (1,114 in Seoul and 1,036 in Jeju-do) were checked for IgG antibody titers using ELISA and for the T. gondii B1 gene using PCR. In addition, participants completed a questionnaire that solicited information on gender, age, occupation, eating habits, history of contact with animals, and travel abroad. The T. gondii B1 gene was not detected in all residents examined. However, ELISA showed 8.0% (89 of 1,114 sera) positive for IgG antibodies against T. gondii in Seoul and 11.3% (117 of 1,036 sera) in Jeju-do. In both districts, the positive rates were higher in males than in females, and those 40-79 years of age showed higher rates than other ages. In Seoul, residents older than 70 years of age showed the highest positive rate, 14.9%, whereas in Jeju-do the highest prevalence, 15.6%, was in those in their sixties. The higher seropositive rate in Jeju-do than in Seoul may be related to eating habits and occupations. The present results and a review of related literature are indicative of an increased seroprevalence of T. gondii in Korea in recent years.

BACKGROUND: The optimal therapeutic strategies for patients with coarctation of the aorta(CoA) and ventricular septal defect(VSD) remain controversial. This study was undertaken to determine the outcome and the need for reintervention following single-stage repair of coarctation with VSD in infants younger than 6 months. MATERIAL AND METHOD: Thirty three consecutive patients who underwent single-stage repair of CoA with VSD, from January 1995 to December 2000, at Sejong General Hospital were reviewed retrospectively. Mean age and body weight at repair were 54+/-37 days(12 days-171 days) and 3.9+/-1.1 kg(1.5~6 kg), respectively. The surgical repair of CoA was performed under deep hypothermic circulatory arrest(CA) in the early period of the study and under regional cerebral perfusion through a direct innominate arterial cannulation without CA in the later period. The technique used in the repair of the CoA was resection and extended end-to-end anastomosis(EEEA; n=16) and extended side-to-side anastomosis(ESSA; n=2) in the early period, and resection and extended end-to-side anastomosis(EESA; n=15) in the later period. The simultaneous closure of VSD was done with a Dacron patch(n=16) and autologous pericardium(n=17). Aortic arch hypoplasia was present in 29 patients(88%) and its types were distal(n=18), complete(n=5), and complex(n=6). RESULT: All procedures without CA were performed in 18 patients(55%) and repair of CoA without CA in 20 patients(61%). The total bypass and aortic crossclamp time were 163+/-68 minutes and 52+/-27 minutes, respectively, and the mean time used for CA was 27+/-11 minutes. There were four early postoperative deaths(12.1%). Twenty nine hospital survivors were followed up for a mean of 38+/-26 months(6 months-78 months) and recurrent coarctation has occurred in 5 patients(17.2%). Two patients underwent balloon aortic angioplasty for recurrent coarctation and the need for reoperation was not present. Actuarial freedom from recoarctation at 1 and 4 years were 85% and 78%, respectively. Actuarial freedom from recoarctation at 4 years was 92% after EESA and 77% after EEEA(p=NS). There was no late death. CONCLUSION: Single-stage repair of aortic coarctation and VSD using extended anastomosis can be performed with the acceptable operative mortality and provides adequate correction of coarctation and low risk of recoarctation.
