  • Blood flow restriction(BFR) exercise is defined as low intensity and short term exercise using pneumatic pressure belts at the top of limbs, which affects the physiological functions of the body. The purpose of this study was to investigate the effects of walking exercise with BFR on inflammatory index, isokinetic muscle function, and thigh circumference in obese women. Eleven obese women(> BMI $25kg/m^2$ & > body fat 30%) wore pneumatic pressure belts on both femurs and performed walking exercise twice per day, 3 days/wk for 4 weeks (walking 2 min; resting 1 min). Data analysis was carried out using paired t-test. Body weight, BMI, and body fat significantly decreased after exercise(p<.05), and right thigh circumference significantly decreased(p<.05). The concentration of plasma IL-6 significantly increased(p<.05) after exercise. TNF-${\alpha}$ level was not statistically different but tended to slightly increase. CRP slightly decreased, although it did not reach statistical significance after exercise. Muscle strength significantly increased in the $60^{\circ}/sec$ of right/left side extension, left side flexion, and $180^{\circ}/sec$ of left side extension after training(p<.05). These results suggest that 4 weeks of blood flow restriction walking exercise has positive effects on inflammatory index and isokinetic muscle function. Therefore, we consider that blood flow restriction exercise can be used for treatment of obesity, related chronic diseases, and metabolic syndrome. Further, blood flow restriction exercise for a short time has similar effects as a high intensity resistance program.

  • Purpose: The purpose of this study was to evaluate the posterior cruciate ligament (PCL) reconstruction with single bundle, single-incision technique using Achilles tendon and tibialis anterior allograft with ligament remnant preservation. Materials and Methods: Twenty six patients underwent PCL reconstruction was included. There were 21 males and 5 females. Mean age was 32 years. Used graft was a fresh frozen Achilles tendon allograft (group I, 14 cases) and tibialis anterior allograft (group II, 12 cases). Arthroscopic PCL reconstruction was performed using transtibial, single-incision and single bundle technique with remnant preserving as possible. For clinical evaluation, range of motion, posterior drawer test, Lysholm score, Tegner activity scale, International Knee Documentation Committee (IKDC) grade and posterior stress radiograph were used. The mean follow-up period was 21.6 months (12-40 months). Associated injuries were 5 medial collateral ligament injuries, which were treated by conservative method. Results: Range of motion (ROM) was returned to normal range in 24 cases, but ROM deficit under $10^{\circ}$ flexion was 2 cases at final follow-up period. Preoperative posterior drawer test was 17 cases in grade II and 9 cases in grade III. At final follow-up 13 cases returned within normal grade, 7 cases grade I and 6 cases grade II posterior instability. Lysholm mean score was improved from preoperatively 62 to 90 at final follow-up period. Tegner activity mean scale improved from preoperatively 3.5 to 5.6 at final follow-up period. IDKC grade was grade A was 3 cases, grade B 17 cases, grade C 6 cases. In posterior stress radiograph, posterior displacement was improved from mean 12 mm preoperative to 4.5 mm at final follow-up. There were no statistical differences between two groups in clinical evaluations. There were two cases of re-rupture of graft at the bone-tendon junction in group I. Conclusion: We had successful results of PCL reconstruction with single-incision, single bundle technique using Achilles and tibialis anterior allograft without difference between two groups in patients with PCL injury. There were more re-rupture of graft in Achilles tendon group.

  • The case management has been applied to improve the quality of care and the cost-effectiveness in the most health care institutions. In a way of case management, the critical pathway(CP) has been executed in many acute care settings, focused on the diagnoses with high cost, high volume, and high risk. This study was conducted to develop a case management program using CP as an intervention of patients with lumbar spinal stenosis for the surgery of posterolateral fusion, and to find out the effects of the critical pathway on the quality of nursing care, patient satisfaction as an outcome of care, length of stay and medical charge, and nurses' job satisfaction. At the same time, patients' functional states were checked with the Oswestry Low Back Pain Index, to show that the CP would not decrease the patients' function compared to the control group. The subjects were 25 control patients with a usual operation of lumbar fusion and 25 experimental patients with CP. They were all female, aged $50s{\sim}70s$, admitted in the Orthopedic surgery ward of a university hospital. Also nurses on the floor using CP were asked to respond to measurement tool of job satisfaction before and after the application of CP, and compared with other nurses on the different wards. Data were analyzed with t-test for continuous variables and chi-square for non-parametric variables in addition to the reliability test of the measurement tools. The results of this study were as followings: 1. Patients' functional states The differences in Oswestry scores of the experimental and control groups assessed at preoperation and at discharge were not statistically significant. The change in scores of the experimental group measured at preoperation and at discharge was larger than that of the control group, however the difference was not statistically significant. The results indicate that the CP did not decrease the patients' functional status. 2. The quality of nursing care The total of quality of nursing care given to the experimental group was better than that of the control group(P=.000). In addition, the experimental group showed better scores of quality of every item of care than the control group(P=.000 -.004). 3. Patient satisfaction Patients of the experimental group were not more satisfied with general care than the control group. But they were more satisfied with discharge care of 'explanation about medication, body posture, and brace application' and 'explanation about the adjustment of daily living and exercise during recovery'(P= .047, P=.028). 4. Nurses' job satisfaction Nurses working with the CP showed more job satisfaction than before the CP introduction(P=.048). But the control group of nurses on a different floor showed no change in job satisfaction at the same period of time. 5. Length of stay and medical charge The mean length of stay of the experimental group was shorter than that of the control group without statistical significance. The charge of medication and treatment of the experimental group were smaller than that of the control group(P=.011, P=.000). The results of the study support that the case management using critical pathway enables to improve the quality of care and job satisfaction, to reduce the medical charge, and consequently to increase satisfaction with care. However, the case management should be instituted focusing on the quality improvement of nursing and the client satisfaction, not just for the purpose of cost-effectiveness of health care facilities.

  • The goal of the present study was to evaluate the effects of PNAM appliance and cheiloplasty on alveolar molding. Samples consisted of 16 unilateral cleft lip and palate infants (10 males and 6 female, mean age=37.0 days after birth, average alveolar cleft gap=10.46m), who were treated with PNAM appliances by one orthodontist and rotation- advancement cheiloplasty by one surgeon in Seoul National University Hospital. Average duration of alveolar molding treatment was 13.10 weeks and these patients were recalled at average 8.31 weeks after cheiloplasty. These patients' models were obtained at initial visit (T0, mean age : $37.0\pm27.89$ days after birth), after successful alveolar molding (T1, mean age : $119.25\pm40.18$ days after birth), and after cheilopasty (T2, mean age : $190.81\pm42.78$ days after birth). Seven linear and five angular variables were measured using 1 : 1 photometry and soft ware program(V-ceph. Cybermed. Seoul, Korea). Paired t-test was performed to investigate statistical significance at p<0.05 level. 1 The posterior parts of alveolar segments were the stable structures during alveolar molding treatment period and after cheiloplasty in infants. 2. The closure of cleft gap during alveolar molding was usually due to backward bending of the whole part of the greater segment. 3. Although forward growth of the greater segment was hindered by alveolar molding, it resumed after cheiloplasty. 4. Increase of anterior inter-segment angle after cheiloplasty was due to the molding effect of the lip scar pressure.

  • Purpose : We evaluated the diagnostic value of susceptibility-weighted imaging (SWI) for the detection of developmental venous anomaly (DVA). Materials and Methods: Retrospective review of 1068 brain MR examinations found 28 DVAs in 28 patients (2.6%) on contrast-enhanced T1-weighted images. SWI, T2, and FLAIR images of 28 patients with DVA and 28 sex- and age-matched control patients without DVA were analyzed by blinded readers on each type of sequences. All images were independently reviewed by two radiologists who were blinded to other MR imaging finding. In cases of discrepancy, two reviewers reached a consensus later. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of each MR sequence for the detection of DVA were determined. Statistical analysis was performed by using the Mcnemar test. The significance level was p < 0.05. Results: The sensitivity, specificity, PPV, and NPV of SWI for the detection of DVA were 85.7%, 92.9%, 92.3%, and 86.7%, respectively. T2 and FLAIR images showed sensitivity of 35.7% and 35.7%, specificity of 92.9% and 96.4%, PPV of 83.3% and 90.9%, and NPV of 59.1% and 60.0%, respectively. On SWI, the sensitivity and NPV for the detection of DVAs were significantly higher than those of T2 and FLAIR images (p < 0.05). Conclusion: SWI was sensitive and specific for the detection of DVA.

  • Purpose : Pleural effusion is a common complications of pediatric bacterial pneumonia. Intrapleural administration of fibrinolytic agents such as urokinase have been used in the management of complicated parapneumonic effusions. But the safety and effectiveness of intrapleural urokinase instillations in children has not been confirmed. The aim of this study is to evaluate the safety and effectiveness of intraperitoneal urokinase in children. Methods : We reviewed a total of 29 children diagnosed as parapneumonic effusion with septation by chest CT or chest ultrasonography. We divided them into two groups. Fourteen children treated with urokinase after thoracostomy (Group A) were compared with 15 children treated only with thoracostomy (Group B). The urokinase, 3,000 IU/kg/day, was injected into the pleural cavity twice a day. Results : There was no statistical difference in sex and age between the two groups. Total drainage volume during thoracostomy in group A and B was 375.5 mL and 350.0 mL, respectively. It was not statistically significant. But the amounts of pleural fluid of group A on day 1, day 2 and day 3 were 102.5 mL, 100.0 mL, and 70.0 mL respectively and those of group B on day 1, day 2 and say 3 were 120.0 mL, 50.0 mL and 15.0 mL respectively. To compare group A with group B in the amounts of drainage volume on day 1 was not statistically significant, but the amounts of drainage volumes on day 2 and day 3 in group A were statistically more significant than group B (Day 1 P=0.371, Day 2 P=0.049, Day 3 P=0.048, respectively). The duration of fever, antibiotics, thoracostomy and total hospital days. Were not statistically significant between the two groups. But the frequency of complications in Group A was statictically significantly lower than in group B. Conclusion : Intrapleural instillation of urokinase facilitates the drainage of loculated pleural effusions, especially during the first 3 days, and it could reduce complications, such as pleural thickening, surgical managements, re-positioning of tube and re-thoracostomy. So intrapleural urokinase injection was and effective and safe treatment of pleural effusion in children (P=0.014).

  • Background: Complications after surgery for esophageal cancer are various and not rare. Among them, pulmonary complication is well known as one of the most important insults which has negative influence on the postoperative course and results in mortality. So we attempted to analyze the factors which may have relation to postoperative pulmonary complication. Material and Method: The retrospective study was undertaken in 87 patients who underwent curative surgery for esophageal cancer from Jan. 1996 to Aug. 2005. We divided them into two groups, patients with pulmonary complication (group A, n=28), without pulmonary complication (group B, n=59). Statistical analysis was performed with Fisher's exact test. Result: The postoperative pulmonary complication developed in 28 patients ($32\%$). There was no difference between two groups in past medical history, preoperative pulmonary function, surgery time, anastomosis method, pathologic stage, and trial of neoadjuvant therapy. Age and incidence of cervical anastomosis were significantly higher in group A (p=0.001, p=0.023). The rate of routine postoperative ventilator care was significantly higher in group S (p=0.007). Chest tube indwelling time and hospital stay were significantly longer in group A (p=0.011, p=0.001). There were 6 postoperative deaths ($6.8\%$) and 5 deaths were related to pulmonary complication. Pneumonia was the most common cause of death and MRSA (methicillin resistant staphylococcus aureus) was the most common organism in sputum culture. Conclusion: Pulmonary complication after esophageal cancer surgery was the most important cause of death. Pulmonary complication was closely related to patient's age and cervical anastomosis. We think postoperative routine ventilator care is helpful for prevention of pulmonary complications, especially MRSA pneumonia, and reducing mortality.

  • Purpose: Acute symptomatic seizures are caused by structural changes, inflammation or metabolic changes of brain, such as tumor, stroke, meningitis, encephalitis and metabolic disorders. Inherited metabolic disorders that can cause seizures are organic acidopathies, lysosomal storage disorders, peroxisomal disorders and mineral disorders. We have done this study to find out the importance of organic acidopathies causing seizure disorders in Korean childhood and adolescent patients. Method: Retrograde analysis for 1,306 patients with seizure disorders whose clinical informations are available and have done urine organic acid analysis for 5 years period, between Jan. 1st 2007 to Dec. 31th 2011. Statistical analysis was done with Student's t test using SPSS. Result: Out of 1,306 patients, 665 patients (51%) showed abnormalities on urine organic acid analysis. The most frequent disease was mitochondrial respiratory chain disorders (394, 30.1%), followed by mandelic aciduria (127, 9.7%), ketolytic defects (81, 6.2%), 3-hydroxyisobutyric aciduria (19, 1.4%), glutaric aciduria type II (10, 0.8%), ethylmalonic aciduria (4), propionic aciduria (4), methylmalonic aciduria (3), glutaric aciduria type I (3), pyruvate dehydrogenase deficiency (3), pyruvate carboxylase deficiency (3), isovaleric aciduria (2), HMG-CoA lyase deficiency (2), 3-methylcrotonylglycinuria (2), fatty acid oxidation disorders (2), fumaric aciduria (1), citrullinemia (1), CPS deficiency (1), MCAD deficiency (1). Conclusion: On neonatal period, mandelic aciduria due to infection was found relatively frequently. Mitochondrial disorders are most frequent etiologic disease on all age group, followed by ketolytic defects and various organic acidopathies. The number and diversities of organic acidopathies emphasize meticulous evaluation of basic routine laboratory examinations and organic acid analysis with initial sample on every seizure patient.

  • Backgrounds : Gastric cancer is one of the most frequent causes of cancer-related deaths worldwide. Gastric cancer patients frequently exhibit distant metastasis at the time of diagnosis and at present, there is no standard regimen after operation or chemotherapy to prevent metastasis and recurrences. Aims : The objective of the study was to compare the overall survival and disease free survival in patients treated with wheel balance therapy (WBT) with patients treated with WBT alone or the combination of WBT and conventional therapy and see if there were any significant improvements in survival between the two groups. Setting & Design : East-West Cancer Center at Daejeon University: retrospective study. Materials & Methods : We retrospectively analyzed 62 patients with stage III (40 patients) and stage IV (22 patients) gastric cancer who have received operation or chemotherapy 2 months prior to beginning WBT. The patients followed the WBT protocol which includes herbal medicine such as PSM capsules, OnePlus syrup, or HAD capsules which prevent metastasis and recurrences. Overall survival and disease free survival were analyzed and the patients were treated for 89.55 weeks and 49.27 weeks (median value) for stages III and IV, respectively. Statistical analysis used : Overall survival and disease free survival were estimated using the Kaplan-Meier method and the WBT and combination treatment arms were compared using the log rank test. Results : For stage III, the 3 year overall survival was 78.5% and disease free survival was 78.3%. Metastasis and recurrence occurred in 13 of 40 patients (32.5%). For stage IV, the 2 year overall survival was 18.2% and disease free survival was also 18.2%. Metastasis and recurrence occurred in 19 of 22 patients (86.4%). No significant difference was found statistically between the WBT alone and combination treatment arms though the combination regimen showed superiority (overall survival p=0.5093, disease free survival p=0.5175). Conclusions : WBT yielded satisfactory results in prolonging survival and preventing metastasis and recurrence in gastric cancer patients. The major treatment unit of WBT is composed of herbal medications (HAD, PSM capsules, OnePlus syrup) and a randomized, prospective study should be carried out using only this treatment unit in the future.

  • Background: Cerebrovascular diseases are known to show different patterns of incidence among regions and races. Therefore, it is very important to determine the incidence pattern of a specific area in order to diagnose, treat and prevent cerebrovascular diseases. The objective of the present study is to analyze quantitatively the incidence ratios of hemorrhagic and ischemic cerebrovascular diseases by season, by gender and by age. Methods: The subjects of this study were 1603 patients hospitalized for hemorrhagic or ischemic cerebrovascular diseases at the Department of Neurosurgery or the Department of Neurology of a University Hospital. Statistical analysis of data used Excel 2003 of Microsoft, and t-test was conducted using ORIGIN 6.0 of MICROCAL. Results: In the subjects, the incidence ratios of hemorrhagic and ischemic cerebrovascular diseases for four years, the period of this research, were 38.55% and 61.45%, respectively. The mean and standard deviation of age when hemorrhagic cerebrovascular diseases occurred were 58.20 and 12.60, respectively, and the percentages of subjects in their 40s, 50s, 60s and 70s were all around 20%. On the contrary, the mean and standard deviation of age when ischemic cerebrovascular diseases occurred were 65.01 and 13.59, respectively. The average age of patients with ischemic cerebrovascular diseases was older than that of patients with hemorrhagic brain diseases, and the percentages of those in their 60s, 70s and 80s were 15.53%, 37.06% and 27.72%, respectively. The season when hemorrhagic cerebrovascular diseases appeared most frequently was winter, which was followed by summer, spring and autumn. The season when hemorrhagic cerebrovascular diseases appeared most frequently was spring, which was followed by summer, winter and autumn. Conclusions: In this study, the incidence rates of hemorrhagic and ischemic cerebrovascular diseases were 38.55% and 61.45%, showing the rising percentage of ischemic cerebrovascular diseases. For making adequate prevention and disease control plans, it is considered necessary to make a long-term epidemiological investigation of cerebrovascular diseases.
