BACKGROUND: Computerized topography(CT) is the method of choice for establishing patients with abdominal and/or pelvic trauma. However, the sensitivity of CT far detecting bladder rupture has been questioned. We investigated the roles of CT as the initial evaluation of abdominal and pelvic trauma in diagnosis of bladder rupture. METHODS: We reviewed the medical records and radiographs of 53 patients with bladder rupture for last 5 year. And among them, all radiographs of 30 patients who underwent both CT and retrograde cystography were evaluated independently by two urologists who had no knowledge of the patients' final diagnosis. RESULTS: Among 30 patients, all of patients were correctly diagnosed by retrograde cystography, but the CT diagnosis was correct in only 23 patients(76.7%), who were 17 patients(85.0%) with intraperitoneal rupture and 6 patients(60%) with extraperitoneal rupture. And of the 7 patients who were negative by the CT, all showed the sign of inadequate bladder distension. CONCLUSION: We suggest that CT, if properly performed with adequate bladder filling, is as sensitive for detection of bladder injuries as conventional cystography. Especially, in trauma patients with hematuria and suspected other organ injury, CT-cystography with retrograde filing may be as accurate as conventional cystography and obviate the need for an additional plain film cystography,

Numerous operations have been described to treat the recurrent anterior dislocation of the shoulder, but no one procedure was accepted as the choice of operation. We perforemed 6 Bristow procedures and 5 combined Bankart and Putti-Platt procedures and examined six shoulders by arthroscope from sep. 1989 to Sep. 1992, and we analysed the pathologic feature and the results of them. The average follow-up period was 2.2 years. 1. There were 8 males and 3 females and their average age was 33.7 years. The mean age in initial dislocation was 28 years. 2. The number of recurrent dislocation before operation was 17.9 times and the average duration of the disease was 5.7 years. 3. The pathologic lesions observed in intraoperative field were Hill-Sachs lesion (72.7%), Bankart lesion (90.9%), and the erosion of the glenoid rim (54.5%). On arthroscopic examination of 6 cases, Hill-Sachs lesion was found in 4 cases, Bankart lesion was seen in all of 6 cases, and the erosion of the glenoid rim was observed in 4 cases. 4. The average range of the limitation of external rotation was 17.3 and its significant difference was not observed between 2 operative groups. 5. By Rowes rating sheet, 4 cases of 5 combined Bankart and Putti-Platt operations were excellent and 1 case was good. 6. In conclusion, combined Bankart and Putt-Platt operation was considered as a good surgical procedure in the treatment of recurrent anterior dislocation of the shoulder.

Plgmented villonodular synovitis is a benigh lesion that develops in joint lining and is characterized by an exuberant inflammation. Many authors have discussed etiology, clinical and radiological features, pathology and treatment regarding the disease. This occurs most commonly in the knee joint as a monoarticular proliferative process, but rarely in the hip joint. It is a nonneoplastic disease but may develop as an aggressive local process with bone and joint destruction. Sometimes clinician can not detect it in early time because of its nonspecific clinical findings and misdiagnose it as sarcomatous process. So, early diagnosis of hip joint involvement is necessary because destruction of the femoral head and acetabulum is the ultimate outcome if treatment is not intiated. We report two cases of pigmented villonodular synovitis involving the hip joint, which were diagnosed and treated in our department.

Most insects including the honeybee cause erythema and edema at the site of a sting in non-allergic individuals. This reaction usually resolves within a few days. However, in certain cases, the persistence of inciting materials in the cutaneous tissue may promote a local inflammatory foreign body reaction. Localized nodular lesions were seen in our two patients and erythemstous patches were present in one patient due to rarely encountered complications induced by retained sting materials. In these cases histopathology showed multiple foci of foreign body granuloma containing yellow refraetile material in the center surrounded by histiocytes and foreign body giant cells. The granulomatous skin lesions in these patients were treated with intralesional injections of triamcinolone acetonide and partial excisions of the nodular masses were performed.

A case of unilateral pulmonary vein atresia with absent right superior vena cava in 9 years-old boy is described with a discussion. Clinical findings were similar to other reports and consisted of hemoptysis, dyspnea and anemia. A chest X-rary revealed irregular vascular marking on left lung fiedld and increased interstitial marking on right upper lung field. The diagnosis could be confirmed with radionuclide perfusion study, MRI scan of heart and great vessels and angiography which demonstrated a small right pulmonary artery, pruned its peipheral branches, stasis of contrast material and nonvisualization of draining righ pulmonary veins. Pneumonectomy, patch angioplasty of diaphargm excision will be necessary.

BACKGROUND: Improvements in catheter equipments and increasing experience of the operators have brought about a broadening of the indications and applications of percutaneous transluminal coronary angioplasty(PTCA). In particular, coronary angioplasty has been employed in total occlusions.We evaluated the initial success rate and safety of PTCA total occulsive coronary artery disease. METHODS: To assess the success rate and safety of PTCA total coronary artery occlusion, the data of 24 patients(male 19, female 5, mean age 55+/-9 years), in whom PTCA for total occlusion were performed, were examined. RESULTS: Primary success rate of procedure was 66.7%(16 out of 24 lesions).The success rate according to the duration of total occlusions was 8 out of 11(72.7%) with occlusions<4 weeks duration and 3 out of 7(42.9%) with occlusions>4 weeks duration(p=0.07). There was no difference in success rate according to vassel dilate(left anterior descending 75.0%, right coronary 44.4%) and length of occluded lesion(0.93%+/-0.47%cm, p=0.35). Eight procedural failures included inability to cross the lesion with a guide wire in 6 and inability to dilate the lesion in 2, but there was no emergency coronary bypass surgery or cardiac death. CONCLUSION: Even though the recanalization of occluded coronary arteries has a lower initial success rate than angioplasty for stenotic arteries, PTCA in total occlusion can be performed as a safe and effective therapeutic modality in selective patients.

BACKGROUND: Indications and applications of percutaneous transluminal coronary angioplasty(PTCA) have been broaden recent years. We evaluated the initial success rate and safety of PTCA in mulitiple lesions and vessels. METHODS: To assess the success rate and safety of PTCA In mulitiple lesions and vessels, the data of 60 lesions from 28 patients(male 23, female 5, mean age 56+/-12 years), in whom PTCA for multiple lesions and vessels were performed, were examined. Initial results and complications were compared in 37 lesions undergoing multivessel and 23 lesions undergoing multilesion PTCA. RESULTS: Overall primary success rate of procedure was 82%(49 out of 60 lesions). Angioplasty was attempted in mean 2.1 stenotic lesions per patient. Primary success rate per lesion was 84%(31 of 37) among those who underwent multivessel and 78%(18 of 23) among those who underwent multilesion PTCA(p>0.05). Success rate according to the combination of dilated vessels was 85.7%(12 of 14) in left anterior descending(LAD) and left circumflex(LCX), 83.3%(10 of 12) in LAD and right coronary artery(RCA), 100.0%(4 of 4) in LAD and diagonal branch, RCA and LCX in 75.0%(3 of 4), and 66.7%(2 of 3) in LAD, LCX and diagonal branch. Eleven failures(18.3%) included inability to pass the guide wire cross the lesion or inability to locate the balloon catheter in 5(8,3%), abrupt closure in 2(3,3%), coronary spasm in 1(1.7%) and major branch occlusion in 3(5.0%), but there was no emergency coronary bypass surgery or cardiac death. CONCLUSION: Coronary angioplasty in selected patients with multivessel and multilesion coronary artery disease might be useful and have relatively good initial results, but the long-term efficacies with other forms of treatment must be evaluated prospectively.
