This study was designed to determine if topical cardiac hypothermia is a necessary adjunct to intraoperative myocardial protection. In this study, 105 patients ranging in age from 22 to 74 years were included. Myocardial temperature was measured at the ventricular septum. All patients received cold blood cardioplegia without topical cooling. In most of the patients(90%) the myocardial temperature was dropped to 10-15degrees C without topical cooling. In Group A, myocardial temperature was dropped rapidly to 10-15degrees C with, 1,000ml or less cardioplegic solution. In Group B, the amount of cardioplegic solution required for lowering myocardial temperature to 10-15degrees C was 1,000-2,000ml. In Group C, myocardial temperature was not dropped below 18degrees C or cardioplegic solution over 2,000ml was required for lowering myocardial temperatur. Eight patients(8/61, 8%) in group A, 12 patients(12/35, 34%) in group B and 8 patients(8/9. 89%) in group C had Complete obstructive lesions in at least one of major branches of coronary artery(p=0.001). Myocardial perfusion score was different among the groups(8.27+/-2.27 in group A, 9.98+/-2.21 in group B, 10.30+/-2.49 in group C, p<0.002). These data suggest that routine topical hypothermia may be unnecessary if myocardial temperature of less than 15degrees C could be attained with cold blood cardioplegia, especially in case of myocardial perfusion score below 10.

In consideration of the potential deleterious effects of blood transfusion, the effect of acute anemia on the healing of both small (SI) and large intestinal (LI) anastomoses was evaluated. Thirty-six white rabbits underwent resection of both the mid-ileum and the distal colon with primary anastomosis of each. One and two weeks post operation, all anastomoses were assessed by anastomotic bursting pressure (ABP) and histologic evaluation utilizing a modified Erhlich/Hunt scale with grading of the WBC influx, blood vessel ingrowth, fibroblast proliferation, and collagen deposition. Results were analyzed using oneway analysis of variance (ANOVA) and the Chi-Square approximation with p<0.05 being considered significant. The SI ABP, reported in mmHg SE, of the anemic rabbits was decreased at one week vs. the controls (234 mmHg 17 vs. 201 mmHg 16), reaching significance at two weeks (190 mmHg 6 vs. 257 mmHg 17). A decreased LI ABP was found at one week, though not quite reaching singnificance (p=0.06). Recovery to control values occurred by two weeks. Histologic assessment (anemia vs. control) demonstrated a uniform decrease in WBC infiltration, reaching significance in the LI group at two weeks. Blood vessel ingrowth was likewise depressed, but did not achieve significance. The collagen contents of both the SI and the LI groups at two weeks decreased, as were the SI fibroblast proliferation at one week (p<0.05). This study demonstrates that severe, acute anemia in rabbits undergoing intestinal anastomoses severely alters histologic parameters in both the SI and the LI anastomoses while decreasing the overall strength of the SI anastomoses.

From 1989 to 1996, push back palatoplasty, 2-flap palatoplasty and Furlow's palatoplasty were the main procedures of cleft palate repair in our institute. To compare the maxillary growth state of patients in each palatoplasty group, evaluation of dental occlusion and cephalometric analysis were performed in total 50 patients. The results were as follows: 1. Normal control group was composed of 17 children who didn't have cleft lip or cleft palate. Mean values of cephalometric data in the normal control group were 6.19 cm in SN length, 1.17cm in ONA length, 7.29cm in effective maxillary length 53.88degree in SNO angle, and 82.41 degree in SNA angle. 2. Fourteen patients who underwent push-back palatoplasty showed anterior crossbite in all cases. SNO angle and SNA angle were significantly decreased compared to the normal control group, which indicated significant impairment of maxillary growth. 3. In seventeen patients who underwent 2-flap palatoplasty, 7 patients showed anterior crossbite. Cephalometric parameters showed no significant difference compared to the normal control group. 4. Nineteen patients underwent Furlow's palatoplasty. In this group, 3 patients had anterior crossbite. Cephalometric parameters showed no significant difference compared to the normal control group. Although this report was based on data acquired from patients before the age of complete maxillary growth, our results suggested that each palatoplasty would have a different influence on maxillary growth.

Thirty one free vascularized fibula bone grafts were performed for treatment of osteonecrosis of the femoral head in 26 patients, 24 men and 2 women aged from 16 to 48(mean:32 years). Twenty one patients had unilateral disease. Five patients had bilateral disease underwent staged bilateral free vascularized fibula grafts three months apart. Associated etiological factors included alcohol(9 patients), steroid(7 patients), and trauma(one patient). The condition was considered idiopathic in the remaining 9 patients. Radiologic staging by Ficat included stage 1 in one hip, stage II in 15 hips, stage III in 14 hips, and stage IV in one hip. A skin island flap was used for monitoring purpose for the grafted fibula. One monitoring, flap was necrotized due to vascular occlusion but the fibula bone graft was left in place to use as a nonvascularized bone graft. Average follow-up period was 21 months in 31 hips. Pain was relieved in 28 hips(93.3 percent) and aggravated in 2 hips(6.7 per cent). On radiographic evaluation, 26 hips(86.7 per cent) demonstrated excellent preservation of the femoral head contour. Progressive collapse of the femoral head (greater than 1-2 mm) occurred in 2 hips, i mm depression in one hip with stage III and 2 mm collapse in one hip with stage IV. In conclusion, the free vascularized fibula bone graft is an excellent treatment modality for preserving the femoral head and relieving symptoms in cases of the osteonecrosis of the femoral head.

OBJECTIVE: The aim of the present study was to understand biomechanical characteristics during the process of initiation of gait (IOG) from the standing position in hemiplegic patients. METHOD: We recorded the ratio of the vertical forces of both limbs to body weight and the movement of net center of pressure (COP) on two force platforms during the process of initiation of gait (IOG) from standing in 10 normal control and 10 hemiplegic patients and processed these data using ELITE DMA acquisition program. All data were collected with uninvolved limb and involved limb and compared each other by independent samples t-test. RESULTS: 1) In 10 hemiplegic patients, nine patients began taking a step with an uninvolved limb in the first, followed by an involved limb. 2) The period of IOG of the swing limb was 0.80 sec when patients walked with an uninvolved side and those of the stance limb was 1.60 sec with involved side. When the control group walked, the period of IOG of the swing limb was 0.70 sec and those of stance limb was 1.50 sec. The period of IOG of the swing limb in uninvolved side and those of the stance limb in involved side showed significant longer than control group. 3) The latency of IOG of swing and stance limb was significantly more prolonged than control groups. 4) Anteroposterior (AP) and mediolateral (ML) distance of net COP from release to unloading with uninvolved limb showed significant longer than control groups. 5) The velocity of net COP displacement from start to release with involved limb was significantly slower than control groups. CONCLUSION: This pattern of IOG could be used as one of the tools to evaluate postural control during gait training in the hemiplegic patients with gait disabilities, and it can be used as a basis for specific therapeutic intervention, and it allows evaluation of the effectiveness of treatment.

OBJECTIVES: To examine the current status of hospital information systems (HIS), analyze the effects of Electronic Medical Records (EMR) and Clinical Decision Support Systems (CDSS) have upon hospital performance, and examine how management issues change over time according to various growth stages. METHODS: Data taken from the 2010 survey on the HIS status and management issues for 44 tertiary hospitals and 2009 survey on hospital performance appraisal were used. A chi-square test was used to analyze the association between the EMR and CDSS characteristics. A t-test was used to analyze the effects of EMR and CDSS on hospital performance. RESULTS: Hospital size and top management support were significantly associated with the adoption of EMR. Unlike the EMR results, however, only the standardization characteristic was significantly associated with CDSS adoption. Both EMR and CDSS were associated with the improvement of hospital performance. The EMR adoption rates and outsourcing consistently increased as the growth stage increased. The CDSS, Knowledge Management System, standardization, and user training adoption rates for Stage 3 hospitals were higher than those found for Stage 2 hospitals. CONCLUSIONS: Both EMR and CDSS influenced the improvement of hospital performance. As hospitals advanced to Stage 3, i.e. have more experience with information systems, they adopted EMRs and realized the importance of each management issue.

There are variable types in wrist joint injury. Most common case is simple distal radius fracture. And ulnar head dislocation associated with disruption of distal radioulnar ligament is unusual. Among thease injury types. volar dislocation of ulnar head in the distal radioulnar joint is not common and it is misdiagnosis frequently. So it needs to surgical operation frequently. The author reviews this injury with the relevant literature.

OBJECTIVE: Teeth discoloration is a rare orthodontic complication. The aim of this study was to report the clinical progression of discoloration during orthodontic treatment. METHODS: Discolored teeth, detected during orthodontic treatment between January 2003 and December 2012 by a single dentist using similar techniques and appliances, were analyzed. RESULTS: The total number of teeth that showed discoloration was 28. Progression of discoloration was evaluated in only 24 teeth that were observed without any treatment. During the observation period, the discoloration “improved” in 8 of the 24 teeth (33.3%) and was “maintained” in 16 (66.6%). The electric pulp test performed at the time of initial detection of discoloration showed 14.3% positivity, which improved to 21.4% at the final follow-up. None of the initial and final follow-up radiographic findings showed any abnormalities. CONCLUSIONS: When teeth discoloration is detected during orthodontic treatment, observation as an initial management is recommended over immediate treatments.

BACKGROUND: Nonrheumatic atrial fibrillation is common in elderly and associated with an increased risk for thromboembolism. Left atrial spontaneous echo contrast(SEC) and thrombus. which are easily detected by transesophageal echocardiography(TEE) in patients with rheumatic mitral valve disease and atrial fibrillation, have been known as markers of thromboembolism. However, most of the previous studies on left atrial SEC and thrombus were performed in rheumatic mitral valve disease or various conditions including rheumatic mitral valve disease. Therefore this study was underaken in order to investigatd 1) the prevalence of left atrial SEC and thrombus, and 2) clinical and echocardiographic variables related to left atrial SEC and thrombus in nonrheumatic atrial fibrillation. METHODS: In patients with estabished atrial fibrillation over 7 days, we examined the clinical gistory and performed transthoracic echocardiography(TTE) and TEE simultaneously. Enlisted patients were those without rheumatic mitral valve disease, prosthetic valves, previous thromboembolism, and recent anticoagulant therapy. RESULTS: 1) Left atrial SEC was detected in 32(62.7%) of 51 patients and left atrial thrombus in 10(19.6%). All thrombi were located in the left atrial appendage. 2) In univariate analysis, SEC positive group showed higher prevalence of congestive heart failure(CHF)(56.3% vs 0%, p<0.001), lower ejection fraction(42.2+/-14.1% vs 50.8+/-9.7%, p<0.05), lower left atrial appendage blood flow velocity(peak positive flow velocity ; 18.7+/-11.1cm/sec vs 32+/-12.4cm/sec, p<0.01, and peak negative flow velocity ; 21.4+/-12.4cm/sec vs 31.9+/-12.8cm/sec, p<0.01) than SEC negative group. Multivariate analysis identifed CHF as an independent variable related to left atrial SEC(p=0.02, Odds ratio ; 2.38, 95% CI ; 1.18-4.82). 3) In univariate analysis. left atrial thrombus positive group showed higher prevalence of CHF(70% vs 26.8%, p<0.05), larger left atrial demension(34+/-3.4mm/m2 vs 30.6+/-4.6mm/m2, p<0.05) than thrombus negative group. Multivariate analysis identifed CHF as an independent variable related to left atrial thrombus(p=0.04, Odds ratio ; 4.30, 95% CI ; 1.11-16.68). 4) Left atrial thrombus is more frequent in SEC positive group than in SEC negative group(28.1% vs 5.3%), however, there was no statistical significance(p=0.07). CONCLUSION: 1) Left atrial SEC is common in nonrheumatic atrial fibrillation and significantly related to CHF. 2) Left atrial thrombus is frequently detected in SEC positive patients, however, it is more realted to CHF than left atrial SEC itself.
