One of the serious and challenging problems confronting orthopaedic surgeons is an open un-united fracture of tibia. Especially, there are some difficulties in getting bone union on the condition of combining soft tissue defect with infection. In the management of infected un-united fracture of tibia with significant soft tissue loss we attempted a two-stage reconstruction : the first stage consisted of radical sequestrectomy, soft tissue reconstruction, and external fixation, and the 2nd stage consisted of various types of bone grafting and bone fixation. Fifteen patients with open infected un-united fractures of tibia treated with staged reconstruction from September 1982 to August 1987 at Department of Orthopaedic Surgery, Dae-Jeon's St. Mary's Hospital, Catholic University Medical College, were analyzed in clinical aspects and the results of treatment obtained were as follows : 1. Satisfactory bone union was obtained in an average of 6 months after bone graft with a range of 4 months to 12 months. 2. The duration from the injury to bone union was 13 months on an average with a range of 8 months to 19 months. 3. The soft tissue rer.onstruction at the first stage were performed with local flap in 11 cases and muscular flap in 2 cases and musculocuteneous flap in 2 cases. 4. The time interval between 1st stage and 2nd stage was from 1.5 months to 3 months. 5. At the 2nd stage, bone graft were performed with autogenous cancellous bone graft in 11 cases, vascularized osteocutaneous fibular graft in 2 cases and ipsilateral vascularized fibular transference in 2 cases. In summary, a two-stage reconstruction for open infected un-united fracture of tibia is a advisable procedure that leads to bone union with satisfactory return of function.

BACKGROUND: Left ventricular thrombus is a common complication after acute myocardial infarction. Methods and RESULTS: To Study the incidence of left ventricular thrombosis (LVT) after acute myocardial infarction, we performed serial two-dimensional echocardiography (2D-Echo) in 35 consecutive patients with acute myocardial infarction prospectively ; 10 patients had inferior wall myocardial infarction, 25 patients had anterior wall myocardial infarction. 2D-Echo was obtained within 3 days of acute myocardial infarction, at 4-10 days after symptom onset, and 2-4 weeks after symptom onset serially in each case. 19 out of 35 patients received thrombolytic therapy with urokinase. Left ventricular thrombi were identified in 9(25.7%) of the 35 study patients. The location of myocardial infarction was anterior and apical in all cases with left ventricular thrombi. The shape of thrombi was mural in 6 cases and protruding in 3 cases. The incidence of left ventricular thrombi in patients who received urokinase was not significantly different from that in patients who didn't(31.9% vs 18.8%,p=0.22). Wall motion score was significantly higher in patients who developed left ventricular thrombi than in patients who had no left ventricular thrombus(8.2+/-1.9 vs 5.8+/-2.6, p<0.005). All thrombi appeared within 10 days after myocardial infarction. CONCLUSIONS: Thus left ventricular thrombi develops within 10 days following myocardial infarction with large anterior and apical location. The thrombolysis therapy has no effect in the incidence of left ventricular thrombi in this study. But because of confounding effect of thrombolysis and location of myocardial infarction and extent of myocardial infarction, further investigation is needed.

Thirty nine strains and 109 strains of Shigella sonnei were isolated from the outbreaks of Youngchun and Kyungju, respectively, while 15 strains were isolated from sporadic cases of eight regions in Kyungbuk province from September to November in 1998. We investigated the relationship among the S. sonnei strains by using biochemical characteristics, biotyping, antibiotic resistance pattern, and plasmid profile. Among the isolates, seven strains of S. sonnei isolated in Youngchun showed gelatin hydrolyase positive but the others showed gelatin hydrolyase negative. One hundred and fifty two strains were a type, while eleven among thirty nine strains isolated in Youngchun were g type. Antibiotics resistance patterns of S. sonnei strains isolated in Youngchun and Kyungju were significantly different. Thirty nine strains of S. sonnei isolated in Youngchun were resistant to SM, TE, and TMP/SMX, while eighty six of S. sonnei among one hundred and nine strains isolated in Kyungju were resistant to AM, CB, K, SM, TE, and TMP/SMX. Antibiotics resistance patterns of residual twenty three isolates were similar to those of eighty six strains. The Plasmid profiles of strains of S. sonnei isolated from the Kyungju were different from those of S. sonnei strains isolated in Youngchun. The Plasmid profiles of S. sonnei strains isolated from Youngchun were identical to those of a S. sonnei strains randomly selected from the outbreak in Daegu in 1998. The Plasmid profiles of S. sonnei strains isolated from Kyungju were identical to those of two strains of S. sonnei randomly selected from the outbreaks of Kanglung and Wonju in 1998. From the above results, it is considered that the strains of S. sonnei isolated from Kyungju and Youngchun region are not identical clone.

BACKGROUND: Free radical-mediated oxidative damage has been implicated in ischemic brain injury. There are also increasing evidences that nitric oxide is involved in the mechanisms of cerebral ischemia. To elucidate the effect of nitric oxide synthesis inhibition on the hydroxyl radical formation, we used a method based on the chemical trapping of hydroxyl radical in the form of the stable adducts 2,3-DHBA following salicylate adminstration. METHODS: Sprague-Dawley rats were subjected to 15 min of global cerebral ischemia by both carotid artery occlusion plus systemic hemorrhagic hypotension (35 mmHg). Artificial CSF including salicylate (5 mM) was continuously infused through a microdiaysis probe implanted in the left hippocampus CA1. Hippocampal extracellular fluid was sampled at regular intervals before, during, and after ischemia. The levels of 2,3-DHBA were assayed by HPLC with electrochemical detection during 15 minutes of ischemia and reperfusion period. RESULTS: Cerebral blood flow was reduced to 5% level of control in ischemic period, but increased 3 or 4 times in early phase of reperfusion period, and returned to normal 50 to 60 minutes after the cessation of ischemia. Inhibition of NOS by L-NAME did not prevent ischemia-induced 2,3-DHBA elevation, but increased its level during reperfusion. This increase in 2,3-DHBA could be reversed by L-arginine. The elevated 2,3-DHBA after IR in L-NAME treated rats was not due to either changes in CBF or local blood brain barrier permeability. CONCLUSIONS: The above results indicate NO protects brain from damages by hydroxyl radical, at least less than one hour after initiation of reperfusion.

BACKGROUND AND OBJECTIVES: Qualitative oculomotor abnormalities have been reported in parkinsonian patients for many years, but conflicting results have been obtained. This study was performed to evaluate the correlation between the severity of the disease and the abnormalities of the ocular movements in idiopathic parkinson's disease. METHODS: We gave the vestibular function tests in patients with idiopathic parkinson's disease and normal controls. Eye movement recordings were made with automated electronystagmography and rotation test was performed. A total of 46 patients (mean age : 61.2+/-6.7) and 24 controls (mean age : 60.5+/-4.3) were studied. The severity of the disease was divided into two groups by modified Hoehn & Yahr staging ; H-Y stage 1 and 2 as a mild group and stage 3 and 4 as a severe group. RESULTS: Saccadic latency and accuracy, pursuitic gain and velocity, vestibulo-ocular reflex (VOR) suppression by vision were significantly altered in patients, whereas mean velocity of optokinetic nystagmus (OKN) and VOR gain in darkness were normal. Alteration of saccadic latency and accuracy, pursuitic gain and velocity, VOR suppression by vision were profound in the severe group compared with a mild group and controls, but the above parameters did not differ between a mild group and controls. In a hemiparkinson's group, saccadic latency and accuracy, pursuitic gain, OKN mean velocity and gain was not different between the both sides. CONCLUSION: The results indicate that severe Parkinson's disease damages nigrostriatal or other specific pathways which were involved in the regulation of the saccadic, pursuitic and pursuitic-mediated visual fixation system. In a hemiparkinson's group asymmetric damage of dopaminergic innervation which was involved in the regulation of ocular movements was not found.

Endovascular treatment of isolated bilateral common iliac artery aneurysm (CIAA) requires salvage of at least one internal iliac artery to prevent complications such as ischemic buttock claudication. We treated a case of bilateral CIAAs using an internal iliac branched stent graft. We report a case of a 58-year-old man who presented with bilateral CIAAs. The left internal iliac artery was occluded with coil embolization. The right internal iliac artery was saved by using a branched stent graft. The aneurysms were excluded with conventional endovascular aneurysm repair. Completion angiography showed technical success. Follow up computed tomography angiogram at three months showed complete exclusion of bilateral CIAAs, no endoleaks, and patent right internal iliac artery. There was no pelvic ischemic complication. We treated successfully a case of isolated bilateral CIAAs using an iliac branched stent graft.

Epidermal growth factor receptor (EGFR) is overexpressed in various malignancies including carcinoma of the breast, lung, esophagus, cervix, and stomach. In patients with cervical carcinoma, its overexpression may be associated with advanced stage and poor prognosis. So, we evaluated the levels of serum EGFR in patients with cervical carcinoma. The level of EGFR extracellular domain was determined in serum from 57 cervical carcinoma patients(adenocarcinoma: 2, squamous cell carcinoma: 39, carcinoma in situ(CIS): 16) and 28 cases of healthy control using enzyme-linked immunosorbent assay(Calbiochem). In invasive carcinoma, serum EGFR level was measured in 11 cases of Stage Ia, 9 cases of Stage Ib, 4 cases of Stage IIa, 15 cases of Stage IIb, 2 cases of stage III patients. The mean ages of the healthy controls, of the wome with carcinoma in situ(CIS), and with invasive cervical carcinoma were not different(49.3, 44,4, 49.5, respectively, p 0.241). The mean serum level of EGFR in healthy control(n 28), carcinoma in situ(CIS)(n 16), and invasive carcinoma patients(n=41) were not significantly different(71.4+/-12.8fmol/ml, 79.2+/-26.8fmol/ml, 61.8+/- 18.4 fmol/ml, respectively, p=0.071). In conclusion, the expression of EGFR was not increased in patients with cervical cancer compared with normal women. And no significant differences were found depending on the clinical stage.

In order to identify the correlations between clinical results and quantitative data of gait analysis, we analyzed the results of 20 cases of total knee joint replacement arthroplasty in 15 patients with degenerative arthritis. We also evaluated the gait analysis of ten age-matched healthy candidates as a control group. Mean follow-up periods were 30 months. Clinical results included post-operative HSS (Hospital for Special Surgery) knee rating scores and the changes of the tibiofemoral angles. The three dimensional gait analysis included clinical assessment, video-taping, three dimensional kinematics and kinetics. The three dimensional kinematics were obtained using a 5 camera VICON system, and the three dimensional kinetic data was collected using two AMTI force plates. There was no statistical difference in linear parameters between the patient and control group. In patients group, however, double support time decreased as the HSS score increased, and range of knee motion and maximum knee flexion increased in accordance with the increase of pain score. Kinematic data of the patients group revealed that some parameters, such as knee flexion during loading response, knee flexion in swing phase, and knee varus during swing phase, were decreased. On the other hand, internal rotation of the knee from initial contact to initial swing was increased when compared with that of control group. There was no significant correlation between the degrees of tibiofemoral angle and coronal plane moment in the patients group. In three cases which showed mild varus instability post-operatively, knee flexion during loading response decreased and valgus moment in midstance increased as compared with the cases without instability. We believe that three dimensional gait analysis will be a good modality for evaluation of the results after total knee arthroplasty. With further accumulation of long term. follow-up data of gait analysis, we might be able to predict the long term results of total knee arthroplasty including possibility of loosening.
