PURPOSE: The aim of this study was to identify the differences of gender and detail items by using landing error scores during drop vertical jumping that can be used in the field for elite fencers and to use them as basic data for prevention of injury. METHODS: The subjects were 42 elite fencers. Independent sample t-test was used to compare the landing error scoring system (LESS) score between the groups. In order to compensate for errors that may occur in multiple comparisons, they are corrected through the Bonferroni collection. The significant differences between the groups were evaluated using Cohen effect difference, and one-way analysis of variance was performed for differences in epee, fleuret, and sabre. RESULTS: The comparison of landing error scores between male and female fencer groups showed that the knee valgus angle at initial contact, lateral trunk flexion angle at initial contact, stance width-narrow, foot position-toe out, symmetric initial foot contact, in the total score of LESS items, female fencer group was higher and statistically significant difference was found. CONCLUSION: In the case of fencing players, there is no significant difference in the LESS scores according to the items. However, when comparing gender, female fencers have higher LESS scores than male fencers; female fencers should be more careful in preventing injuries.

PURPOSE: Popliteal artery entrapment syndrome (PAES) is rare but major cause of non-atheromatous popliteal arterial insufficiency in young. Because of its rareness, it is often neglected or misdiagnosed as thrombosis or embolism. Consequently surgeons would lose the appropriate time of treatment. METHOD: We reviewed 11 cases of PAES from 1994 to 2002 regarding to clinical characteristics, image findings, management and their results. RESULT: Two of 11 patients had bilateral involvement. All patients were male and aged 12 to 45 year old (mean; 32.1). Intermittent claudication was presented as initial symptom in all. One had toe gangrene. Conventional arteriography (11 cases) was used as initial diagnostic method. CT (7 cases) and MR (4 cases) angiography were also used to make diagnosis. Type II PAES were most common in 7 limbs. 11 limbs of 10 patients underwent operation. One was managed conservatively because of advanced liver cirrhosis. Resection of medial head of gastrocnemius and popliteal arterial bypass were performed in 7 limbs. One myectomy with femoroposterotibial bypass, one femoropopliteal bypass without myectomy, and myectomy with patch angioplasty were performed. Postoperative complication occurred in two limbs. One had occlusion of graft, another had occluded segment of endarterectomised popliteal artery. Primary graft patency at 6 mo, 1 yr and 3 yr were 81% 81%, 81% respectively. CONCLUSION: In young patients with claudication who have localized lesion at popliteal artery, clinicians should pay attention to rule out PAES. Accurate diagnosis can be achieved by CT or MR angiography. Early surgical correction is recommended to minimize surgical procedure and reduce complication of the disease.

BACKGROUND: Pleural drainage following video-assisted thoracic surgery has traditionally been achieved with large- bore, semi-rigid chest tubes. Recent trends in thoracic surgery have been toward less invasive approaches for a variety of diseases. The purpose of this study was to evaluate the safety and efficacy of drainage by means of small, soft, and flexible 14Fr Blake drains. MATERIAL AND METHOD: Between December 2007 and March 2008, 14Fr silastic Blake drains were used for drainage of the pleural cavity in 37 patients who underwent a variety of video- assisted thoracic surgical procedures at our institution. RESULT: The average postoperative length of hospital stay was 3.26 days (range, 2~12 days), Blake drains were left in the pleural space for an average of 3.15 days (range, 1~7 days), and the average amount of drainage was 43.8 ml/day. The maximal amount of blood removed daily by a Brake drain was as much as 290 mL. There were no drain-related complications. Blake drains seemed to cause less pain while in place, and particularly at the time of removal. CONCLUSION: The use of a Blake drain following minor thoracic surgery appeared to be safe and effective in drainage of fluid or air in the pleural space, and were associated with minimal discomfort.

PURPOSE: To evaluate the efficacy of catheter-directed thrombolysis in treating symptomatic deep venous thrombosis (DVT) in lower limbs. METHODS: Between Jan. 1999 and Dec. 2002, 29 consecutive patients with DVT had received thrombolytic therapy. The male: female ratio was 6: 23 and the mean age was 50.3+/-13.5 years. The mean duration of symptom was 9.9+/-22.1 days. Catheter-directed infusions of urokinase were administrated via ipsilateral popliteal veins and the angioplasty and stent placement performed after the thrombolytic procedure. The mean dosage of urokinase and duration of thrombolysis were 2, 435, 000+/-887, 000 units and mean duration of thrombolysis was 36.8+/-17.9 hours. Oral medication of warfarin continued at least six months or more. To evaluate the venous patency, duplex ultrasonography or CT venography were performed. RESULTS: Lysis was complete in 17 patients (58.6%, all acute DVT), partial in 11 (37.9%), with only one patient failing. Iliac vein stenosis had shown in 16 patient after thrombdysis. Which were treated with balloon angioplasty and stent insertion. As a postprocedural complication, vaginal bleeding occurred in two patients; one was treated with transfusion but the other stopped without treatment. CONCLUSION: Catheter-directed thrombolysis with urokinase is effective for the treatment of DVT in lower limbs. However further study will be reguired to evaluate the relationship between the incidence of postthrombotic syndrome and thrombolytic therapy alone.

BACKGROUND AND OBJECTIVES: This study aims to evaluate that usefulness of the endoscopic ear surgery (EES) through the systematic review. SUBJECTS AND METHOD: We searched literatures in literature databases (MEDLINE, EMBASE, Cochrane Library, etc.). Inclusion criteria is 1) studies of patients with chronic otitis media, otitis media with effusion, cholesteatoma, conductive hearing loss, mixed hearing loss etc. 2) studies in which a transcanal endoscopic surgery was performed; and 3) studies in which one or more of the appropriate medical outcomes have been reported. We excluded that 1) non-human studies and pre-clinical studies; 2) non-original articles, for example, non-systematic reviews; editorial, letter and opinion pieces; 3) research not published in Korean and English; and 4) grey literature. Finally, 65 articles were selected and those results were analyzed. RESULTS: The safety of the EES was reported in 61 articles. Some studies reported damaged facial nerve or perilymph gusher but these are the complications that can arise due to the characteristics of the disease and not due to the EES and other reported complications were of similar or lower level in the intervention group rather than the microscopy group. The effectiveness of the EES was reported in 23 articles. The EES tended to show improved effects in terms of graft uptake status, cholesteatoma removal, and hearing improvement although effective outcomes of most studies reported no significant difference between EES and microscopic ear surgery. CONCLUSION: EES is a safe and effective technique and as it is less invasive than the microscopic ear surgery.
