Primary malignant fibrous histocytoma (MFH) of pleura is very rare. Upon microscopic examination, the tumor was characterized by storiform pattern of growth and intense, diffuse immunostaining for alpha l-antichymotripsin. We report a case of primary malignant pleural fibers histiocytoma with extension to lung, which was managed by complete excision of pleural mass and lobectomy with thoracoplasty.

BACKGROUND: Majority of patients with mitral valve disease and chronic atrial fibrillation can resume sinus rhythm with the maze procedure. The purpose of this study is to identify mid-term outcome and possibility of recurrent atrial fibrillation in the patients who underwent mitral valve operation and the maze procedure. MATERIAL AND METHOD: A retrospective study was undertaken on 11 consecutive patients(including 10 patients with rheumatic mitral valve disease) operated on for mitral valve disease and chronic atrial fibrillation. Maze II and its modified procedure were performed in 6 patients and maze III and its modified procedures in 5 patients. Postoperative left atrial contractility was compared between the patients that underwent mitral valve operation and maze procedure and the patients with mitral valve procedure and medication of anti-arrhythmic drugs. RESULT: Five(83.3%) of 6 patients with maze II procedure and all 5 patients(100%) with maze III procedure resumed sinus rhythm. In 1(20%) of 5 patients with sinus rhythm after maze II procedure and 2(40%) of 5 patients with sinus rhythm after maze III procedure, atrial fibrillation recurred 23, 2, and 13 months after the operations, respectively. None of three patients with the modified procedure had recurrence of atrial fibrillation. Of 3 patients with recurrent atrial fibrillation, 2 patients resumed sinus rhythm and 1 still had atrial fibrillation. After the maze procedures, only 4 (40%) of 10 patients with sinus rhythm presented left atrial contraction, and their mean velocity of mitral 'A' wave was lower than that of the patients who resumed sinus rhythm with only valve replacement and anti-arrhythmic drugs. CONCLUSION: Although the maj ority of patients with mitral valve disease and chronic atrial fibrillation can resume sinus rhythm with the maze procedure associated with mitral valve operation, atrial fibrillation may recur in mid-term. Also, the left atrial contractility may be very poor in patients who resumed sinus rhythm with maze procedure.

Displaced fracture of the ankle are probably the most common skeletal injury managed today by open reduction and internal fixation. But, it is recommended that metallic implant might be removed to restore normal biomechanical forces on hone and to reduce discomfort directly under the skin. in order to reduce the resources needed for the removal of metallic fixation devices, absorbable impiants of biodegradable synthetic polymers were deveioped. However reports of clinical application of such implants have so far been very few. This prospective study represents the good resuits in 15 displaced non-comminuted closed malleolar fractures of the ankle treated using hiodegradahle internal fixation in department of orthopedic surgery of Kwang Myung Sung Ae general hospitai from June I 995 to December 1996. The results were as follows 1. All cases were united and the average time for union was 7.6 weeks. 2. As a results of comparison with normal side, a restriction of 10 degrees or more of dorsiflexion of the ankle joint was present in 4 cases, a restriction of 20 degrees or more of plantar tlexion was present in 2 cases, a restriction of supination was present in 3 cases and a restriction of plantar flexion was present in 4 cases. 3. According to Phillips functional scoring scale, 4 cases were excellent, 7 cases good, 4 cases fair and no cases were poor. 4. There were no complications in all cases.

BACKGROUND: The Y-composite graft of internal thoracic artery and radial artery is commonly used in coronary bypass surgery. The aim of this study is to look for a way to raise the free flow of the internal thoracic graft and to see flow dynamics of the Y-graft. MATERIAL AND METHOD: In 15 patients undergoing coronary bypass surgery, free flow of the in-situ internal thoracic artery graft was measured using two different papaverine application methods; extraluminal papaverine spray in 7 patients and intraluminal papaverine injection in 8. In 18 other patients for whom the Y-graft was used, total free flow and flow changes from the two ends were measured. RESULT: The free flow of the in-situ internal thoracic artery graft almost doubled with internal papaverine injection than with external papaverine spray (47.7+/-9.6 mL/min vs. 100.8+/-26.3 mL/min, p<0.001). Total flow of the Y-composite graft was significantly more than either flow of the internal thoracic artery end or radial artery graft end (173.3+/-45.3 mL/min vs. 121.1+/-34.3 mL/min or 117.5+/-42.8 mL/min). When both ends of the Y-composite graft were opened, free flows from the two ends were similar (85.4+/-27.8 mL/min vs. 87.9+/-42.4 mL/min, p=0.772). The flow of one end of the Y-composite graft was increased significantly by clamping of the other-end than when both ends were opened. CONCLUSION: Intraluminal papaverine injection is very effective in raising free flow of the internal thoracic artery graft, and the free flow of the Y-composite graft of in-situ internal thoracic artery and free radial artery graft is more than that of the in-situ internal thoracic artery graft. The flow of one end flow of the Y-graft may be altered by the flow change of the other end.

BACKGROUND: The most important factor in preventing sternal complications is stable sternal approximation. We have tried to find the most effective sternal closure method by examining the incidence of sternal dehiscence with or without infection in patients with cardiac surgery through median sternotomy. MATERIAL AND METHOD: This study was performed in 489 patients over 45 years of age with median sternotomy for open cardiac surgery. Simple closure with interrupted 6 wires was performed in 159 patients, figure-of-8 closure technique in 119, overlapping interrupted closure using 10 wires in 150, and combined closure technique of interrupted simple closure and figure-of-8 suture closure in 61. Two hundred thirty-four patients underwent valve and aortic operations and 213 patients coronary artery bypass surgery. RESULT: Sternal dehiscence with or without infection occurred in 12 (2.5%) patients. The complication developed in 5 of 159 patients (3.1%) with six interrupted simple closure, in 4 of 119 patients (3.4%) with figure-of-8 closure, and in 3 of 150 patients (2.0%) with overlapping interrupted closure using 10 wires, but there was no complication in 61 patients with combined closure technique (relative risk for other closure techniques, p<0.05). There was no significant difference in the incidence of the sternal complication between valve and aortic operation group and coronary artery bypass group (3.0% vs 2.3%, not significant), but diabetes mellitus was a significant independent risk factor (odds ratio and multivariate analysis, p<0.05). CONCLUSION: The sternal closure technique that combines simple interrupted suture closure and figure-of-8 suture closure may be a more useful technique to enhance sternal stabilization compared to other closure techniques, such as simple interrupted closure, 8-figure closure, and overlapping interrupted closure.

In Langerhans cell histiocytosis, diabetes insipidus is the most common endocrinologic complication. We experienced a case of Langerhans cell histiocytosis, involving pituitary stalk and lung. The patient was a 43 year old male with complaint of polyuria and polydipsia. The water deprivation test was carried out to confirm the diagnosis of diabetes insipidus. We found multiple small cysts and nodules in HRCT of lung, and diagnosed Langerhans cell histiocytosis by transbronchial lung biopsy, The patient was managed conservatively with DDAVP nasal spray. The polyuria,polydipsia was relieved completely. After that, we follow up and observe closely the patients lung and pituitary lesion.

Short stature and gonadal dysgenesis are two characteristic clinical features of Turners syndrome. Very rarely, patients with Turners syndrome may menstruate and even be fertile. We experienced a case of Turners syndrome with spontaneous sexual development and menstruation. A 16-year-old girl was referred for severe anemia and menometrorrahgia. She had nearly normal features, with the exception of a short stature and a single right kidney. Also, she had spontaneous development of secondary sexual characteristics. We performed and anemia study and evaluated her short stature. In chromosomal study of her bone marrow and peripheral blood lymphocytes, she was revealed to have monosomy 45,X. Herein, this case is reported, with a brief review of literature

The coronary arteries are also subject to congenital anomalies of both minor and major consequence. Hemodynamically significant primary anomalies of the coronary arteries are those which alter myocardial perfusion. There are four major types : coronary artery fistula, origin of the left voronary artery from the pulmonary artery, congenital coronary stenosis or atresia and origin of the left or right coronary artery from the opposite sinus of Valsalva with subsequent passage of the vessel between the aorta and right ventricular infundibulum. Minor anomlies are the variation of the origin of the coronary arteries from the aorta with normal distal circulation. We can see more coronary anomalies associated with congenital cardiac anomalies, probably representing a circulatory response to the primary intracardiac defect. We present a total of 76 cases of congenital coronary anomalies, reviewing 3946 cases of angiocardiography or selective coronary arteriography, performed during last 8 years at Sejong General Hospital.
