Résumé
BACKGROUND: For decades, trauma has been recognized globally as a major cause of death. Reducing the mortality of patients with trauma is an extremely pressing issue, particularly for those with severe trauma. An early and accurate assessment of the risk of mortality among patients with severe trauma is important for improving patient outcomes.METHODS: We performed a retrospective medical record review of 582 patients with severe trauma admitted to the emergency department between July 2011 and June 2016. We analyzed the associations of in-hospital mortality with the baseline characteristics and initial biochemical markers of patients with severe trauma on admission.RESULTS: The overall in-hospital mortality rate was 14.9%. Multivariate logistic regression analysis showed that the patient’s Rapid Emergency Medicine Score (REMS; odds ratio [OR], 1.186; 95% confidence interval [CI], 1.018–1.383; p=0.029), Emergency Trauma Score (EMTRAS; OR, 2.168; 95% CI, 1.570–2.994; p<0.001), serum lactate levels (SLL; OR, 1.298; 95% CI, 1.118–1.507; p<0.001), and Injury Severity Score (ISS; OR, 1.038; 95% CI, 1.010–1.130; p=0.021) were significantly associated with in-hospital mortality.CONCLUSION: The REMS, EMTRAS, and SLL can easily and rapidly be used as alternatives to the injury severity score to predict in-hospital mortality for patients who present to the emergency department with severe trauma.

Résumé
Two patients were admitted to our department because of recent aggravation of claudication in the leg, which was exacerbated by walking. They were diagnosed as having a Baker cyst or acute thrombosis in the popliteal fossa at another hospital. There was no evidence of ischemia, and the ankle brachial index was normal. Computed tomography and magnetic resonance imaging were performed, revealing a cystic mass of the popliteal artery (PA). Intraoperatively, the cystic lesion was found within the adventitia of the PA; based on the biopsy findings, both patients were diagnosed as having adventitial cystic disease of the PA.

We report the case of a patient with penetrating chest trauma (right chest) who had undergone a left pneumonectomy due to pulmonary tuberculosis 24 years ago. We performed an emergent thoracotomy, finding an opening of the penetrating wound in a lower-lobe basal segment of the right lung. A stapled tractotomy was performed along the tract. Bleeding control and air-leakage control was done easily and rapidly. The patient was discharged without any complications on the seventh day of admission. Tractotomy can be a good option for treating penetrating lung injuries in patients with limited lung function who need emergent surgery.

Thymoma is the most common neoplasm of the anterior mediastinum and has malignant potential. Germ cell tumors (GCTs) found in the anterior mediastinum are usually benign, and malignant GCTs, such as seminomas, are rare. Histologically, mediastinal seminoma is indistinguishable from testicular seminoma except for site-associated morphological features such as lymphoid follicular hyperplasia. Therefore, excluding metastasis is very important. Recently, we treated a young adult patient with multiple thymic masses that occurred simultaneously. The patient underwent a thymectomy for the removal of the mediastinal masses, one of which was diagnosed as type B2 invasive thymoma, and two of which were diagnosed as primary mediastinal seminomas with massive follicular hyperplasia. The patient received adjuvant chemotherapy after surgical resection. To our knowledge, this is the first description of a thymoma and a mediastinal seminoma occurring simultaneously in the thymus. We present this case along with a literature review.

PURPOSE: This study was performed to compare the treatment outcomes between endovascular aneurysm repair (EVAR) and open surgical repair (OSR) of abdominal aortic aneurysms (AAAs) in a South Korean population. MATERIALS AND METHODS: We performed a retrospective review of the medical records of 99 patients with AAAs who were managed at Gyeongsang National University Hospital between January 2005 and December 2014. We reviewed the demographic characteristics and perioperative treatment outcomes of patients with AAA undergoing EVAR or OSR. In-hospital mortality and reintervention rates were assessed and compared between the EVAR and OSR groups. RESULTS: In-hospital mortality was not significantly higher in the OSR group versus the EVAR group (3.8% vs. 8.7%, respectively, P=0.41). Intervention time (209.6 mins vs. 350.9 mins, P < 0.001) and length of hospital stay (7.79 days vs. 17.46 days, P < 0.001) were significantly longer in the OSR group vs. the EVAR group. Median follow-up time was 24.1±20 months for the EVAR group and 43.9±28 months for the OSR group. The cumulative rate of freedom from reintervention at 60 months was 62.0% for the EVAR group and 100% for the OSR group (P < 0.001). CONCLUSION: EVAR was favorable in terms of intervention time and length of hospital stay, but the long-term durability of EVAR remains open for further debate.

BACKGROUND: Unfractionated heparin (UFH) has unstable pharmacokinetics and requires close monitoring. The activated partial thromboplastin time (aPTT) test has been used to monitor UFH therapy for decades in Korea, but its results can be affected by numerous variables. We established an aPTT heparin therapeutic range (HTR) corresponding to therapeutic anti-Xa levels for continuous intravenous UFH administration, and used appropriate monitoring to determine if an adequate dose of UFH was applied. METHODS: A total of 134 ex vivo samples were obtained from 71 patients with a variety of thromboembolisms. All patients received intravenous UFH therapy and were enrolled from June to September 2015 at Gyeongsang National University Hospital. All laboratory protocols were in accordance with the Clinical and Laboratory Standards Institute guidelines and the College of American Pathologist requirements for aPTT HTR. RESULTS: An aPTT range of 87.1 sec to 128.7 sec corresponded to anti-Xa levels of 0.3 IU/mL to 0.7 IU/mL for HTR under our laboratory conditions. Based on their anti-Xa levels, blood specimen distribution were as follows: less than 0.3 IU/mL, 65.7%; 0.3–0.7 IU/mL (therapeutic range), 33.6%; and more than 0.7 IU/mL, 0.7%. No evidence of recurring thromboembolism was observed. CONCLUSION: Using the conventional aPTT target range may lead to inappropriate dosing of UFH. Transitioning from the aPTT test to the anti-Xa assay is required to avoid the laborious validation of the aPTT HTR test, even though the anti-Xa assay is more expensive.

BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) is an important global health problem. Furthermore, the time to identify a positive sputum culture is an important risk factor for the spread of tuberculosis, and several factors can predict a prolonged time to culture conversion. Moreover, the relationship between poor nutritional status and infectious disease is clearly established. Therefore, the present study aimed to investigate the association between body mass index (BMI) and sputum culture conversion within 3 months among patients with MDR-TB. MATERIALS AND METHODS: We retrospectively evaluated 218 patients with MDR-TB who were treated at a large tuberculosis referral hospital in South Korea between January 2005 and December 2010. The outcome of interest was defined as sputum culture conversion within 3 months, and we analyzed the association between BMI and this outcome. RESULTS: Among the 218 patients, 53 patients (24.3%) had a low BMI (<18.5 kg/m²). In the multivariate Cox proportional-hazards regression analysis, failure to achieve sputum culture conversion within 3 months was independently associated with having a low BMI (hazard ratio [HR]: 1.741, 95% confidence interval [CI]: 1.006–3.013; P = 0.047) and a positive sputum smear at the initiation of therapy (HR: 8.440, 95% CI: 1.146–62.138, P = 0.036). CONCLUSION: Low BMI (<18.5 kg/m²) was an independent risk factor for failure to achieve sputum culture conversion within 3 months among patients with MDR-TB.

Mediastinitis is a life-threatening disease, and effective drainage is needed to treat mediastinitis with abscess formation. We recommend an alternative drainage method using chest tube binding with a Silastic Penrose drainage tube. The use of a Silastic Penrose drainage tube may help to manage mediastinitis with abscess formation. This method facilitates effective draining and prevents tissue adhesion.

Acute lymphoblastic leukemia (ALL) is the most common form of childhood cancer and may exhibit central nervous system (CNS) involvement. Advances in chemotherapy and effective CNS prophylaxis have significantly decreased the incidence of CNS relapse of ALL to 5-10%. Here, we report the case of a patient with isolated CNS relapse of standard risk group pre-B-cell type ALL in an 11-year-old girl, relapsed 3 years after successful completion of chemotherapy. An 11-year-old girl visited our hospital complaining of headache, dizziness, vomiting, and visual field defects. Neurological examination revealed left-side homonymous hemianopsia. Brain magnetic resonance imaging showed a large irregular dural-based sulcal hematoma in the right parietal and occipital lobes. Surgery to remove the hematoma revealed the existence of hematopoietic malignancy after pathologic evaluation. Bone marrow biopsy was subsequently performed but showed no evidence of malignancy.

Percutaneous vertebroplasty is a relatively easy and minimally invasive procedure used in treating vertebral fractures. However, the procedure has many complications, one of which is bone cement leakage, which happens frequently. Leakage to the paravertebral venous system, in particular, may lead to especially devastating consequences. Here we report a case of a 65-year-old male patient with an intracardiac foreign body (bone cement) that generated a perforation on the right ventricle, and result in hemopericardium after percutaneous vertebroplasty. We performed open heart surgery to remove the foreign body.

BACKGROUND: Ulinastatin has anti-inflammatory properties and protects organs from ischemia/reperfusion-induced injury. The aim of this study was to investigate whether ulinastatin provides a protective effect on a regional myocardial ischemia/reperfusion injury in an in vivo rat heart model and to determine whether the anti-inflammatory response is related to its myocardial protective effect. METHODS: Rats were randomized to two groups. One group is received ulinastatin (50,000 U/kg or 100,000 U/kg) diluted in normal saline and the other group is received normal saline, which was administered intraperitoneally 30 min before the ischemic insult. Reperfusion after 30 min of ischemia of the left coronary artery territory was applied. Hemodynamic measurements were recorded serially during 6 h after reperfusion. After the 6 h reperfusion, myocardial infarct size, cardiac enzymes, myeloperoxidase activity, and inflammatory cytokine levels were compared between the ulinastatin treated and untreated groups. RESULTS: Ulinastatin improved cardiac function and reduced infarct size after regional ischemia/reperfusion injury. Ulinastatin significantly attenuated tumor necrosis factor-alpha expression and reduced myeloperoxidase activity. CONCLUSIONS: Ulinastatin showed a myocardial protective effect after regional ischemia/reperfusion injury in an in vivo rat heart model. This protective effect of ulinastatin might be related in part to ulinastatin's ability to inhibit myeloperoxidase activity and decrease expression of tumor necrosis factor-alpha.

PURPOSE: A retrospective investigation of the clinical and radiologic features as well as the bronchoscopic appearance was carried out in patients with endobronchial aspergilloma. MATERIALS AND METHODS: Ten patients with endobronchial aspergilloma diagnosed by bronchoscopy and histological examination were identified at the Gyeongsang University Hospital of Korea, from May 2003 to May 2009. RESULTS: The patients included 9 men and 1 woman, and the age of the patients ranged from 36 to 76 (median, 58 years). The associated diseases or conditions were: previous pulmonary tuberculosis in 7 patients, lung cancer in 2 patients, pulmonary resection in 1 patient, and foreign body of the bronchus in 1 patient. The chest radiologic finding showed fibrotic changes as a consequence of previous tuberculosis infection in 6 patients and a mass-like lesion in 2 patients. Two patients had a co-existing fungus ball, and an endobronchial lesion was suspected in only 2 patients on the CT scan. The bronchoscopic appearance was a whitish to yellow necrotic mass causing bronchial obstruction in 7 patients, foreign body with adjacent granulation tissue and whitish necrotic tissue in 1 patient, whitish necrotic tissue at an anastomosis site in 1 patient, and a protruding mass with whitish necrotic tissue in 1 patient. CONCLUSION: An endobronchial aspergilloma is a rare presentation of pulmonary aspergilosis and is usually incidentally found in immunocompetent patients with underlying lung disease. It usually appears as a necrotic mass causing bronchial obstruction on bronchoscopy and can be confirmed by biopsy.

BACKGROUND: We investigated changes in the International Normalized Ratio (INR) and its measurement interval in patients with thromboembolic events who were treated by low intensity anticoagulation therapy after isolated mechanical aortic valve replacement. MATERIALS AND METHODS: Seventy-seven patients who underwent surgery from June 1990 to September 2006 were enrolled in the study and observed until August 2008. The patients were followed up at 4~8 week intervals and their warfarin (Coumadin)(R) dosage was adjusted aiming for a target range of INR 1.5~2.5. The rate of thromboembolic events was obtained. Changes in the mean INR and INR measurement interval were comparatively analyzed between the normal group (event free group, N=52) who had no anticoagulation-related complications and the thromboembolic group (N=10). Hospital records were reviewed retrospectively. RESULTS: The observation period was 666.75 patient-years. Thromboembolic events occurred in 10 patients. The linearized occurrence rate of thromboembolism was 1.50%/patient-years. Actuarial thromboembolism-free rates were 97.10+/-2.02% at 5 years, 84.30+/-5.22% at 10 years, and 67.44+/-12.14% at 15 years. The percentages of INR within the target range and mean INR were not statistically significantly different for the normal and thromboembolic groups. However, the mean INR during the segmented period just before the events showed a significantly lower level in the thromboembolic group (during a 4 month period: normal group, 1.86+/-0.14 vs. thromboembolic group, 1.50+/-0.28, p<0.001). The mean intervals of INR measurement during the whole observation period showed no significant differences between groups, but in the segmented period just before the events, the interval was significantly longer in thromboembolic group (during a 6 month period: normal group, 49.04+/-9.47 days vs. thromboembolic group, 65.89+/-44.88 days, p<0.01). CONCLUSION: To prevent the occurrence of thromboembolic events in patients who receive isolated aortic valve replacement and low intensity anticoagulation therapy, we suggest that it would be safe to maintain an INR level above 1.8 and to measure the INR at least every 7~8 weeks.

Apical muscular ventricular septal defects (VSDs) are relatively rare conditions among all the different types of VSDs. Apical VSDs are difficult to treat because of they are difficult to visualize through a trans-atrioventricular approach, and especially in infants. Treatment by left ventriculotomy is associated with long-term ventricular dysfunction. Catheter-based intervention still shows less than satisfactory results and this type of intervention may not be possible in small infants. This report describes the benefits of right apical ventriculotomy in terms of successful closure of the lesion without harming the ventricular function.

BACKGROUND: It is well known that propofol protects myocardium against myocardial ischemia/reperfusion injury in the rat heart model. The aim of this study was to investigate whether propofol provides a protective effect against a regional myocardial ischemia/reperfusion injury in an in vivo rat heart model after 48 h of reperfusion. METHODS: Rats were subjected to 25 min of left coronary artery occlusion followed by 48 h of reperfusion. The sham group received profopol without ischemic injury. The control group received normal saline with ischemia/reperfusion injury. The propofol group received profopol with ischemia/reperfusion injury. The intralipid group received intralipid with ischemia/reperfusion injury. A microcatheter was advanced into the left ventricle and the hemodynamic function was evaluated. The infarct size was determined by triphenyltetrazolium staining. The serum level of cardiac troponin-I (cTn-I) was determined by ELISA (enzyme-linked immunosorbent assay). RESULTS: Propofol demonstrated protective effects on hemodynamic function and infarct size reduction. In the propofol group, the +dP/dt(max) (P = 0.002) was significantly improved compared to the control group. The infarct size was 49.8% of the area at risk in the control group, and was reduced markedly by administration of propofol to 32.6% in the propofol group (P = 0.014). The ischemia/reperfusion-induced serum level of cTn-I was reduced by propofol infusion during the peri-ischemic period (P = 0.0001). CONCLUSIONS: Propofol, which infused at clinically relevant concentration during the peri-ischemic period, has delayed myocardial protective effect after regional myocardial ischemia/reperfusion injury in an in vivo rat heart model after 48 h of reperfusion.

BACKGROUND: Video assisted thoracic surgery has been widely accepted for the treatment of primary spontaneous pneumothorax. MATERIAL AND METHOD: We retrospectively reviewed the medical records of 89 primary pneumothorax patients who had undergone thoracoscopic bleb ligation from February 2002 to June 2006, and we assessed the patients for recurrence. The mean follow-up period was 65 months. RESULT: Pneumothorax recurred in 7 patients (8%) during the follow-up period. CONCLUSION: Thoracoscpic bleb ligation might be an acceptable alternative technique for treating primary spontaneous pneumothorax.

OBJECTIVE: The study reports the clinical outcomes and complication rates of microsurgical clipping of unruptured paraclinoid aneurysms. METHODS: From July 1997 to December 2008, 61 patients underwent microsurgical clipping for 61 unruptured paraclinoid aneurysms in our institute. Entire medical records, radiographic data, and operation records were reviewed retrospectively. RESULTS: After the microsurgical clipping, complete obstruction was achieved in 56 patients (91.8%). Visual disturbance (nine cases, 14.8%) was the most frequent complication. Overall, 59 patients (96.7%) had a good long-term outcome (Glasgow outcome scale score of 4-5 3 months post-operatively). CONCLUSION: For patients with paraclinoid aneurysms, satisfactory outcomes can be achieved by microneurosurgical management. These results will be useful when considering treatment of an unruptured paraclinoid aneurysm.
