Severe ankle sprain secondarily leads to chronic lateral ankle instability in 20-30%. Many surgical procedures have been presented for reconstruction of the lateral ankle instability, but controversy still remains for the ideal surgical option. Brostrom procedure or its modifications have been widely used but they have some limitations for the instabilities for the over-weight, physically high demanding patients and especially for significantly deficient or attenuated ligaments. Moreover the tenodesis procedures using peroneus brevis tendon are non-anatomical and sacrifice important lateral stabilizing tendon. Therefore recently, many reconstructive procedures for lateral ankle instability utilizing free allograft or autograft tendon have been introduced to anatomically stabilize the lateral ligaments to various degrees.

PURPOSE: Bone bruises of patients with acute traumatic knee injuries, that are not found on simple radiograph, can be found on magnetic resonance imaging (MRI). The purpose of this study is to evaluate the frequency and locations of bone bruises on MRI in acute traumatic anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) injury. MATERIALS AND METHODS: 25 and 19 MRls, in which acute traumatic ACL and PCL injury was pre sent and there was no abnormality in simple radiograph, were reviewed. MRI was taken within 51 days of injury. A bone bruise was determined as a geographic and nonlinear area of signal loss on T1 images and increased signal intensity on T2 images involving the subcortical bone. RESULTS: In 16 patients with bone bruises and acute ACL injury, bone bruises were found in the lateral compartment of the knee in 15 (93.8%) patients. The most common area was the lateral tibial plateau (11 cases, 68.8%) and the second was lateral femoral condyle (9 cases, 56.3%). In 5 patients with bone bruises and acute PCL injury, bone bruises were found in the lateral compartment of the knee in all 5 (100%) patients. The most common area was lateral tibial plateau (4 cases, 80%) and the second was lateral femoral condyle (2 cases, 40%). CONCLUSIONS: In patients with acute traumatic ACL or PCL injuries the bone bruises are often found on the lateral compartment of the knee, especially lateral tibial plateau and lateral femoral condyle on MRI.

BACKGROUND AND OBJECTIVES: The Epstein-Barr virus (EBV) is a human herpes virus which causes certain type of lymphoma and some epithelial neoplasm such as undifferentiated nasopharyngeal carcinoma. However, the role of EBV as a causative factor in other head and neck tumor especially, in laryngeal squamous cell carcinoma is not fully elucidated. The aim of this study was to analyze the relationship between the prescence of EBV in laryngeal squamous cell carcinoma and clinicopathologic characteristics. MATERIALS AND METHODS: 65 cases of laryngeal squamous cell carcinoma were retrieved from formalin-fixed, paraffin-embedded blocks and analyzed for EBV by immunohistochemical staining. Results : The EBV was detected in 26(40%) of the 65 patients with laryngeal squamous cell carcinoma and 2(10%) of the 20 control ases. In 26 cases of EBV-positive patients, 13(46.4%) cases were supraglottic cancer and 13(35.1%) cases were glottic cancer. CONCLUSION: These results suggest that EBV may possibly play an etiologic role in the pathogenesis of laryngeal squamous cell carcinoma.

We measured changes in sonographic findings of patients with clonorchiasis after a treatment in a highly endemic area. A total of 347 residents showed positive stool results for Clonorchis sinensis eggs in a village in northeastern China, and were treated with praziquantel. Of them, 132 patients underwent abdominal sonography both before and 1 year after treatment, and the changes in sonographic findings of 83 cured subjects were compared. Diffuse dilatation of intrahepatic bile ducts (DDIHD) was found in 82 patients (98.2%) before and 80 (96.4%) after treatment, which was improved in 3, aggravated in 1, and unchanged in 79 patients. Increased periductal echogenicity (IPDE) was observed in 42 patients (50.6%) before and 45 (54.2%) after treatment, which was improved in 5, aggravated in 8, and unchanged in 70 patients. Floating echogenic foci in the gallbladder (FEFGB) was detected in 32 patients (38.6%) before and 17 (20.5%) after treatment, which was improved in 20, aggravated in 5, and unchanged in 58 patients. Improvement of FEFGB only was statistically significantly (P = 0.004). The present results confirm that DDIHD and IPDE persist but FEFGB decreases significantly at 1 year after treatment. In a heavy endemic area, the sonographic finding of FEFGB may suggest active clonorchiasis 1 year after treatment.

BACKGROUND: Opioids are known to increase the incidence of postoperative nausea and vomiting (PONV). Remifentanil is an ultrashort-acting opioid with a potent analgesic effect and is useful for rapid emergence. This study compared the effect of remifentanil on the incidence and severity of PONV and postoperative pain with that of fentanyl in patients undergoing laparoscopic surgery, which is normally associated with a high incidence of PONV. METHODS: Forty-four adult female patients, who were scheduled for laparoscopic ovarian cyst enucleation, were randomly assigned to either the remifentanil or fentanyl group. Anesthesia was induced with propofol after injecting fentanyl 2 microgram/kg or remifentnail 1 microgram/kg and was maintained with sevoflurane. Remifentanil and fentanyl was infused continuously in the range of 0.2-0.5 microgram/kg/min and 0.03-0.05 microgram/kg/min, respectively. Ketorolac 0.5 mg/kg was injected 30 min before the end of surgery. The incidence and severity of PONV and pain were recorded upon arrival at the recovery room and 2, 6, 12 and 24 hours thereafter. RESULTS: The incidence and severity of PONV and pain were significantly higher in the remifentanil group upon arrival at the recovery room than in the fentanyl group. The incidence and severity of PONV and pain at the other measurement times were similar. CONCLUSIONS: Despite the ultrashort action duration of the remifentanil, the incidence and severity of PONV and postoperative pain immediately after awakening was higher in the remifentanil group undergoing laparoscopic ovarian cyst enucleation than in the fentanyl group. However, there were no significant differences after two hours in the recovery phase.

Primary leiomyosarcoma is an extremely rare tumor. We exprienced a case of 46-year-old man with a mass located in the left upper lobe bronchus which was discovered on a chest CT. Cytology of the sputum and bronchoscopic biopses did not reveal any malignant cells. The patient underwent a left sleeve upper lobectomy. The tumor was growing from the left upper lobe bronchus and had partially destroyed the lung parenchyme. The pathologic feature of the tumor was composed of fascicular arrayed cellular spindle cells with blunt-ended nuclei revealed mild to moderate pleomorphism and frequent mitoses (15/10HPF). The immunohistochemical staining was revealed positive reaction for antibody to smooth muscle actin and desmin. We conclude that the tumor is leiomyosarcoma of the lung and then report with a review of the literatures.

BACKGROUND: An increasing number of elderly are referred for open heart surgeries(OHS). These patients are assumed to have significantly increased morbidity and mortality because of compromised functional reserves in their vital organs. We reviewed the results of OHS patients who were 70 years old or older. MATERIAL AND METHOD: Thirty six consecutive septuagenarians underwent OHS from 1995 to 1997. Operations were coronary artery bypass grafting(CABG) in 26 including 3 left main surgical angioplasty, valve replacement in 7, MVR+CABG in 2, and ASD closure+TAP in 1. Statistical tests were carried out to compare survivor group with nonsurvivor group in respect to risk factors including NYHA functional class, LVEF, emergent operation, IABP support, CPB/ACC time, ventilator time cardiac index, ICU stay and hospital stay for operative mortality. RESULT: Operative mortality rate and postoperative complication were 16%(6/36) and 50%(18/36). One-year and 3-year actuarial survival rates were 76%. Nine patients(25%) had major complications including third-degree A-V block(2), respiratory failure(1), stroke(3), renal failure requiring dialysis(3) and postoperative hemorrhage(2). The causes of death were pneumonia(1), bleeding(1), acute renal failure(1), low cardiac output(1), third-degree A-V block(1), and ventricular tachycardia(1). The univariate analysis of mortality shows that NYHA class IV, LVEF<40%, lesser values for C.I, and longer time for ventilatory support were associated with the risk factors(p value=0.03, 0.001, 0.007, and 0.014). The emergent operation, CPB/ACC time, IABP support, ICU stay and hospital stay were not significant. CONCLUSION: We conclude that cardiac operation can be performed in septuagenarians with acceptable outcomes when done in patients with normal to moderately depressed left ventricular function and adequate functional reserves in their vital organs.
