Serum C-reactive protein (CRP) levels and erythrocyte sedimentation rates (ESR) were measured in 46 patients treated with uncomplicated primary hip replacements, 39 total tip replacements and 7 bipolar hip replacements. In uncomplicated primary hip replacements, ESR levels were slightly elevated preoperatively and were variable postoperatively. But CRP was normal before surgery and elevated in postoperative course, but back to normal within three weeks in most cases. Early success of hip arthroplasty is in indicated by normalization of CRP within three weeks, regardless of ESR. Since ESR seems to react somewhat differently from the CRP, both methods are useful in the monitoring of complications after hip arthroplasty.

BACKGROUND: There are many evidences that inflammation is an important determinant of the development of atherosclerosis and one of the systemic markers of inflammation, C-reactive protein(CRP), is associated with extent of coronary artery disease and risk of coronary events. We assessed the time response of CRP response after coronary angioplasty and it's influence on the clinical restenosis in angina patients. MATERIALS AND METHODS: Patients included 36 angina patients undergoing single vessel angioplasty. Levels of CRP were measured before and 12, 24, 48, and 72 hours after angioplasty. Clinical restenosis was assessed at 6 months after procedure. RESULTS: Baseline CRP level was 0.30+/-0.01 mg/dL in stable and 0.46+/-0.28 mg/dL in unstable angina patients(p<0.05). After angioplasty, CRP level was increased with peak at 24 hour and persisted to 72 hours after angioplasty. At 24 hour after angioplasty, the magnitude of CRP change was 0.32+/-0.31 mg/dL in stable and 0.79+/-0.73 mg/dL in unstable angina patient(p<0.05). The change of CRP level was not associated with troponin-T after angioplasty. In unstable angina patients, clinical restenosis was developed in 8% of patients with low baseline CRP levels and in 50% of those with high baseline CRP levels more than 0.6 mg/dL(p<0.05). CONCLUSION: In unstable angina patients, inflammatory response is more increased than stable angina patients, and increased inflammatory response effects on the restenosis after coronary angioplasty.

BACKGROUND: It is well known that intracoronary thrombolysis during the early period of acute myocardial infarction leads to the limitation of myocardial necrosis, preserves left ventricular function, and improves survivals. The recanalization rate of intracoronary rrokinase infusion into infarct-related coronary artery was known as 62-94 percents in previos studies. The various factors influence the outcome of intracoronary thrombolysis, including total dose of urokinase, time from onsrt of chest pain to thrombolysis. The purpose of this study was to evaluate whether the occlusion site morphology influences recanalization rates of intracoronary thrombolysis. METHODS: We evaluated infarct-related coronary artery morphology of 56 acute mycardial infarction patients who performed intracoronary thrombolytic therapy within 6-12 hours after the onset of acute myocardial infarction. Intracoronary urokinase infusion was performed at a rate of 25000 IU/minute. The presence of calcification, collaterals, side branches and the stump site morphologies(thrombus type, pencil type, cutting type) were identified on magnified 35mm cine frames. RESULTS: Reperfusion was successed in 34 patients and failed in 22 patients. There were no statistically significant difference in the pressure of calcification, collaterals, and side branches between success and failure groups. Intracoronary thrombus was identified in 21 percent of success group, but not in failure group. The reperfusion rates according to stump site morphology were 76% in thrombus type, 58% in cutting type, and 42% in pencil type(p<0.05). CONCLUSION: Our study indicates the presence of intracoronary thrombus and the morphology of thrombus type is more effective in intracoronary thrombolysis in acute myocardial infarction. The identification of types of the coronary obstruction will be helpful for the selection of intracoronary thrombolysis in acute myocardial infarction patients. And the results suggest that the difference of stump composition show different stump morphologies.

We experinced a case of 4p+ syndrome in male infant. He had multiple anomalies such as flat occiput, hypertelorism, low set malformed ear, lower anterior hair line, depressed nose, broad nasal bridge, bilateral complete cleft lip and palate, short neck, unusual position of fingers, ventricular septal defect and umblical hernia. He menifested growth and developmental retardation. Karyotype with banding revealed an extra short arm of chromosome 4. The mother's karyotype was normal. His father and father's sister had a translocation between the short arm of chromosome 4 and the short arm of chromosome 9; their karyotypes were 46, XY, t(4;9) and 46, XX, t(4;9), respectively. In this case, trisomy 4p was the result of parental balanced translocatiom. As this is the first case in Korea, it is worthwhile to report with reviewing literature.

The 8 cases of left ventricular thrombus detected by the 2 D echocardiography or left ventriculography, after acute transmural anterior myocardial infarction were effectively lysed by the thrombolytic agents and heparin therapy. The thrombolytic agents were either urokinase or tissue plasminogen activator. Urokinase was infused intravenously at a dose of 1.0 million unit for three days. And tissue plasminogen activator was infused at a dose of 100mg for a day. In all cases, the thrombi were completely lysed. At follow up, no recurrence of left ventricular thrombus was found. We have experienced 2 cases of peripheral embolization in which, left ventricular thrombi were protruding nonmobile type. The one was the embolic cerebral infarction, the other was transient hoarseness and paresthesia on the left foot, which may be transient ischemic attack. These results show that left ventricular thrombi can be treated by intravenous thrombolytic agents without life-threatening complication. However, for the better establishment of the risk and benefit of therapy further investigation is needed.

The American Medical Association's Guides to the Evaluation of Permanent Impairment (Guides) has provided an useful guideline in interpreting information on permanent impairment based on the in-depth knowledge and experience in impairment ratings accumulated for a long period of time. Since its first publication by American Medical Association (1958), as A Guide to the Evaluation of Permanent Impairment of the Extremities and Back', 12 additional guides' has been published by the JAMA over the next 12 years. All the guides were consolidated to become the first official edition of the Guides' in 1971. The 'Guides' has been updated periodically to reflect current scientific clinical knowledge and judgment methods. It has become the best system available to evaluate permanent impairments across many disciplines. The latest sixth edition created a "paradigm shift" in the area of the impairment assessment by introducing a contemporary model of disablement. The standardized methods elaborated in the sixth edition clearly enhances the relevancy of impairment ratings, improves internal consistency of the methods and renders the application of the rating process easier. It adopts the terminology and conceptual framework from the International Classification of Functioning, Disability and Health in order to generate five impairment classes. A diagnosis-based grid has been developed for each organ system. Functional history, physical findings and objective clinical test results are integrated to determine the grade within the impairment class. The Guides' is the most widely used source for assessing and rating permanent impairments in the United States and can be considered as the best available method for the assessment of permanent impairment.

BACKGROUND AND OBJECTIVES: Percutaneuous transvenous mitral commissurotomy(PTMC) has been performed as an effective non-surgical treatment modality of rheumatic mitral stenosis. Mitral regurgitation(MR) as a complication of the procedure occur in 20-53% of the patients. The moderate to severe mitral reguargitation, created by the PTMC, sometimes leads to the requirement for mitral valve replacement, but most of the MR limits the optimal dilation of mitral commissure due to the worry about the progression of the MR. This study was designed to evaluate the occurrence of mitral regurgitation and predictive factors for the moderate to severe mitral regurgitation(grade> or =2) induced by PTMC. METHODS: This study enrolled 46 patients(female 42, mean age 45 years) who have performed PTMC in Yeungnam University Hospital from May 1996 to May 1999. We analyzed the occurrence rate of mitral regurgitation(MR) and predictive factors for MR grade> or =2 after procedure. RESULTS: MR was detected in 35% of the patients prior PTMC, and in 56% after the procedure(grade 1, 30%; grade 2, 15%; grade 3, 11%). 21 cases of the MR was commissure MR as a grade< or =2. MR grade 3, occured in 5 patients, was non-commissure MR caused by the unilateral rupture of the lateral commissure in 4 patients and tearing of the annulus in one patient. On the univariate analysis, patients with MR grade> or =2 showed more frequent atrial fibrillation, mitral regurgitation and fluoroscopic calcification, and had more severe symptoms than patients with MR grade<2 before the procedure. On the analysis of the calcification, there was no significant difference of the leaflet calcification score, but the commissure calcification score was significantly higher in MR> or =2 group than MR<2 group(1.5+/-0.54 vs 2.5+/-0.96, p=.02). On the multivariate logistic regression analysis, independent predictor of MR grade> or =2 was fluoroscopic mitral calcification(OR 6.38, p=.048). CONCLUSION: Mild to moderate commissure MR was observed in most of the patients after PTMC. Commissure calcification have more influence on the development of MR grade> or =2 than valvular calcification, and the fluoroscopic mitral calcification can predict the occurrence of MR grade> or =2 mitral regurgitation after PTMC.

BACKGROUND: It is well known that ischemic preconditioning protects the heart against infarction or arrhythmias from a subsequent ischemic injury. Two phases of the effect of preconditioning has been explored, early protection and second window of protection at 24 hours. The late protection was seen in some animal model, but the precise mechanism is controversal. This study was designed to evaluate the late cardioprotective effect and role of HSP70 in ischemic preconditioning of cat heart. METHODS: Two groups of cats were studied. Control animals were subjected to an episode of 40-min coronary artery occlusion followed by 30-min reperfusion. Experimental animals were subjected to ischemic preconditioning before the 40-min ishcemia/reperfusion. The preconditioning protocol was comprised of three 5-min episodes of ischemia interspersed by 10-min episodes of reperfusion. After sustained ischemia and reperfusion, left ventricular risk area and infart area were measured by injection of Evans blue bye and triphenyltetrazolium staining, and myocardial HSP70 mRNA was examined in risk(left ventricular anterior wall) and nonrisk(left ventricular posterior wall) area using northern blot hybridization. HSP70 mRNA expression was quantified as a percent of GAPDH. The late cardioprotective effects of ischemic preconditioning were determined by infarct size (% area at risk). RESULTS: Infarct size was markedly limited by ischemic preconditioning when compared with the control group (18.5+/-6.9% vs 38.5+/-11.1%; p<0.001). HSP70 mRNA expression in risk area was much higher in preconditioning group than control group(78+/-12% vs 41+/-11%; p<0.01). But, there was no significant difference of HSP70 mRNA expression in the posterior wall between control and ischemic preconditioning group. CONCLUSIONS: These data suggest that ischemic preconditioning have delayed myocardial protective effect from ischemia. The increase in myocardial HSP70 mRNA may be one of the contributing factors to the delayed cardioprotective effects of ischemic preconditioning in cats.

Autogenous costal cartilage graft has been commonly used for reconstruction of auricular deformity. However, the risk of complication and discomfort at the donor site, as well as distortion of the graft due to morphological change in the cartilage have been serious drawbacks to this procedure. Previous studies examining the chondrogenic potential of perichondrium have suggested that perichondrium may be used as graft for cartilage reconstruction. When a perichondrial flap or a free perichondrium was used as graft, new cartilage formed appositional to the grafted perichondrium. However, the neocartilage was often irregular in shape and varied considerably in quantity. In this study, the feasibility of controlling the shape and the mass of neocartilage was investigated using coral, a porous biomaterial, as a template. A coral a template was wrapped with perichondrial flap from the ears of New Zealand white rabbits and placed into a subcutaneous pocket in the rabbits and placed into a subcutaneous pocket in the rabbit's back by incision. A total of 12 animals were used. Formation of new cartilage was later evaluated by gross and histological examination of the perichondrial flap and the coral template. New cartilage was formed in 11 animals. Immature chondrocytes were visible by 3 weeks after the surgery, and by 8 weeks the immature chondrocytes had formed a cartilage. New cartilage was formed only on the surface of the coral template. These results indicated that the shape and the mass of new cartilage may be controlled by using coral template. Therefore, the desired shape of cartilage may be achieved using a coral template of corresponding shape, and this may help in correcting subtle auricular contour defect and in correcting other structural defects that also require new cartilage formation.
